Ileocecal valve-preservation ileocecostomy (IVPI) in infants with extremely short distal ileum after primary stoma.

Preserving the ileocecal valve (ICV) has shown significant benefits. We present our experience with 18 infants who underwent ileocecal valve-preservation ileocecostomy (IVPI) with an extremely short distal ileum after primary ileostomy. A retrospective analysis was conducted on IVPI cases between 2014 and 2020. Medical records were reviewed, including birth weight, age, primary diseases, length of ileus stump, surgical time and procedure, time to enteral feeding, postoperative hospital stay, and complications. Eighteen patients (male: female = 12:6, median birth weight 1305 (750-4000) g, median gestational age 29 + 5 (27 + 6-39 + 6) weeks) were included in the analysis. Causes of surgery included necrotizing enterocolitis (13), ileocecal intestinal atresia (1), ileum volvulus (2), meconium peritonitis (1), and secondary intestinal fistula (1). The median corrected age of ileostomy closure was 3.2months (2.0-8.0months). The distance from the distal ileal stoma to the ICV ranged from 0.5 to 2cm. The median length of the residual bowel was 90cm (50-130cm). ICV-plasty was performed in 3 cases due to secondary ICV occlusion or stenosis. All patients resumed feeding within 6 to 11days after surgery. The postoperative hospital stay ranged from 12 to 108days (median: 16.5days). Complications included incisional infections in 2 cases, anastomotic stricture and adhesive ileus in 1 case, nosocomial sepsis and septic shock in 1 case. All children showed normal growth and development during a 6-65month follow-up. IVPI is safe and feasible for infants with an extremely short distal ileal stump. ICV-plasty could be applicable for cases with ileocecal occlusion/stenosis.

Mesenteric and omental lymphatic malformations in children: seven-year surgical experience from two centers in China

PurposeTo compare the clinical characteristics, surgical management and prognosis of mesenteric lymphatic malformations (ML) and omental lymphatic malformations (OL) in children.MethodsThis retrospective study included 148 ML patients and 53 OL patients who underwent surgical treatment at two centers between January 2016 and December 2022. Details about the patients’ clinical characteristics, cyst characteristics, preoperative complications, surgical methods, and prognosis were retrieved and compared.ResultsNo significant differences in sex ratio, prenatal diagnosis, or age of diagnosis were noted between ML and OL patients. Vomiting was more common in ML patients than in OL patients (46.6% vs. 22.6%, P = 0.002), but OL patients were more likely to be misdiagnosed (35.8% vs. 18.9%, P = 0.012). The size of the cysts in OL patients was significantly larger than that in ML patients (14.0 [4.0–30.0] vs. 10.0 [2.0–50.0] cm, P<0.001), and cysts with turbid fluid were more common in OL patients (38.0% vs. 20.6%, P<0.001). More OL patients than ML patients had preoperative hemorrhage or infection of cysts (41.5% vs. 31.8%, P<0.016). Cyst excision was performed in 137 (92.6%) ML patients and 51 (96.2%) OL patients, and the incidence of postoperative complications was lower (12.6% vs. 4.2%, P = 0.165) among OL patients. The main postoperative complications included adhesive ileus and recurrence of cysts. Additionally, more OL patients than ML patients were treated with laparoscopic surgery (69.8% vs. 39.2%, P<0.001).ConclusionsThere were differences in clinical characteristics, cyst characteristics and preoperative complications between ML and OL patients. Cyst excision was the most common surgical method that was used to treat both ML and OL patients, and laparoscopic surgery could be a feasible surgical approach for treating OL patients with a good prognosis.Trial registrationRetrospectively registered.

Ileo-caecal doughnut bladder augmentation in children with exstrophy– epispadias complex- a study of 100 cases

The small bladder in failed exstrophy needs to be augmented and also accommodate bladder neck surgery, ureteric re-implantations and a catheterizable channel. We present a novel method of ileocecal bladder augmentation providing a non-implanted, un-detached appendicular channel, rendered non refluxing by an ileal "fundoplication". The colonic segment could receive ureteric reimplantation when bladder plate is unsuitable. Operative technique: Bilateral cephalo-trigonal reimplantation and bladder neck surgery is done. The ileocecal segment is isolated and arranged as a ring (doughnut) around the un-detached appendix which is made to pass behind the terminal ileum, through the ileal mesentery and then in front of the ileum as it exits as a catheterizable channel. The bowel segment is opened on the antimesenteric aspect except for the retro appendiceal ileal segment. The opened ileo-caecum is reconfigured as a de-tubularised augmentation pouch while the retro appendiceal ileal segment is wrapped around the appendix like a fundoplication. The colon segment may receive the ureteric reimplantation if required. 100 children (mean age 6.3 years) with failed exstrophy underwent doughnut augmentation (3 neobladders) in 2006-2021. Ninety eight were incontinent, with 30 open/dehisced bladder plate, 48 units were hydronephrotic (HUN), 105 ureters were refluxing (VUR) and eGFR was subnormal in 20 children. 79 children underwent YDL bladder neck plasty and 23 underwent bladder neck closure (primarily in 18). Three infants with HUN did not undergo bladder neck surgery. 126 ureters were reimplanted into the bladder, 44 into the colon segment while 30 were not reimplanted. 95 children are continent on CIC, which was gradually introduced starting with once or twice daily change of indwelling Mitrofanoff catheter leading to regular 3-4 hourly CIC as the child became confident. The appendicular channel was easily catheterizable without any leak in 95, had minor issues in 4 while one necrosed and replaced by a gastric tube. HUN recovered (25/48) or stabilized with a significant reduction in the grade of hydronephrosis (p=0.001). VUR resolved in 90% of bladder reimplants, 85% of colonic reimplants and 70% of non-reimplanted ureters. In the 20 children with compromised renal function eGFR improved (71-106 ml/m2/min) significantly (p=0.036) at follow up (mean 5 years). Urodynamics study (N=33) showed a mean capacity of 95% of expected bladder capacity (EBC) with end filling pressure less than 25cm of water (Mean end filling cystometric pressure=15cm of water). Complications included adhesive intestinal obstruction (N=16) and bladder calculi (N=12). The doughnut ileocecal augmentation provides a easily catheterizable, non-refluxing, appendicular channel, not requiring isolation of the appendix nor its reimplantation into the bladder. The colonic segment can provide a bed for ureteric reimplantation. Dryness with a good capacity bladder and preserved upper tract is achieved.

Duodenocolic fistula healing by pentadecapeptide BPC 157 in rats. A cytoprotection viewpoint.

Using duodenocolic fistula in rats, this study attempts to highlight the particular cytoprotection aspects of the healing of fistulas and therapy potential of the stable gastric pentadecapeptide BPC 157, a cytoprotection mediator (i.e. upgrading minor vessels to induce healing at both fistula's sides). Upon duodenocolic fistula creation (two 'perforated' lesions put together) (assessed at 3, 6, 9, 12, and 15 min), BPC 157, given locally at the fistula, or intragastrically (10 μg/kg, 10 ng/kg), rapidly induces vessel 'recruitment', 'running' toward the defect, simultaneously at duodenum and colon, providing numerous collaterals and branching. The mRNA expression studies done at that time provided strongly elevated (nitric oxide synthase 2) and decreased (cyclooxygenase-2, vascular endothelial growth factor A, nitric oxide synthase (NOS)-1, NOS-3, nuclear factor-kappa-B-activating protein) gene expression. As therapy, rats with duodenocolic fistulas, received BPC 157 10 μg/kg, 10 ng/kg, per-orally, in drinking water till sacrifice, or alternatively, intraperitoneally, first application at 30 min after surgery, last at 24 h before sacrifice, at day 1, 3, 7, 14, 21, and 28. Controls exhibited both defects persisting, continuous fistula leakage, diarrhea, continuous weight loss, advanced adhesion formation and intestinal obstruction. Contrary, all BPC 157-treated rats have closed both defects, duodenal and colonic, no fistula leakage (finally, maximal instilled volume corresponds to healthy rats), no cachexia, the same weight as before surgery, no diarrhea, markedly less adhesion formation and intestinal passage obstruction. Thus, BPC 157 regimens resolve the duodenal/colon lesions and duodenocolic fistulas in rats, and rapid vessels recovery appears as the essential point in the implementation of the cytoprotection concept in the fistula therapy.

Feasibility and safety of laparoscopy in acute non-traumatic emergency abdominal surgery: A prospective study

Introduction: The use of laparoscopy in emergency abdominal surgery is considered high-risk due to its elevated morbidity, requiring expertise in laparoscopic surgery. Objective: Assessing the feasibility, reproducibility, and safety of laparoscopy in non-traumatic acute abdominal surgery. Methods: Descriptive, prospective and evaluative study, conducted between February 2018 and October 2021. We have included in this study: acute appendicitis and its complications, lithiasis acute cholecystitis (LAC), peritonitis by perforation of peptic ulcer, adhesive acute intestinal obstruction, adnexal torsion, extra-uterine pregnancies, and non-specific acute abdominal pain. Results: We operated on 337 patients laparoscopically, with an average of 02 surgeries per medical shift. In 62.6%, surgeries were performed outside of regular working hours. We encountered temporary, material, and human difficulties in 10.8% of the cases. Average age of the patients is 38 years ±15 years. F/H sex ratio =1.29. Diagnostic accuracy of laparoscopy was 100 %. Intraoperative laparoscopic scanning corrected the preoperative diagnosis in 15.73% of cases. Average operative time was 52.09 min ± 24.14 min. One conversion recorded (0.3%). Rate of postoperative complications was 6.2%. These complications are classified at grade I according to the Clavien-Dindo classification in 85.71%. Only one patient (0.3%) required a second operation. Average length of overall hospitalization was 1.5 days. Conclusion: Our results suggest that emergency laparoscopy is feasible, safe, and reproducible. So it can claim to replace laparotomy in the management of acute, non-traumatic abdominal emergencies.

Unformed conglomerate debilitating jejunal fistulas and their two-stage surgical treatment via posterolateral laparotomy

To create a method of two-stage repair of high unformed conglomerate delimited debilitating jejunal fistulas via posterolateral laparotomy with low risk of surgical complications. Methodology and treatment outcomes were analyzed in 37 patients with unformed conglomerate high debilitating delimited jejunal fistulas. Of these, 22 patients underwent one-stage treatment through 2 converging incisions and/or two-stage treatment through anterolateral access. They made up a control group. Fifteen patients in the main group underwent two-stage treatment via posterolateral left-sided laparotomy with unilateral disconnection of jejunum with fistula. In most patients of both groups, fistulas complicated surgery for acute adhesive intestinal obstruction. Topography of adhesions that caused acute intestinal obstruction in both groups was studied in 172 other patients. Identical jejunal fistulas and two different surgical approaches made it possible to consider our groups representative. Two-stage treatment via posterolateral left-sided laparotomy reduced mortality from 63.6±10.2% to 20.0±10.3% (t=11.8; p<0.001). This approach simplified intraoperative diagnostics that became more informative. Posterolateral access increased the quality of anastomosis and safety of viscerolysis. A new two-stage approach with posterolateral left-sided laparotomy allowed atraumatic imposing of inter-intestinal anastomosis with proximal disconnection of jejunal fistula. This exclusion turns the fistula into analogue of the definitive Meidl's jejunostomy, unloads the intestinal anastomosis and increases the quality of suture. New strategy reduced the risk of complications and mortality.

Лікування та профілактика спайкової кишкової непрохідності в дітей

Despite the achievements of modern pediatric surgery, to date there is no single comprehensive approach to the treatment and prevention of adhesive intestinal obstruction (AIO), both primary (prevention of adhesions formation after primary surgery) and secondary (prevention of recurrence). Purpose - to study the clinical effectiveness of treatment, primary and secondary prevention of postoperative intestinal adhesive obstruction in children. Materials and methods. An examination and analysis of medical records of 119 children aged 5 months to 17 years who were treated at the Pediatric Surgery Clinic of Ivano-Frankivsk National Medical University over the past 10 years for post-operative AIO was carried out. In 35 (29.41%) children a positive effect was achieved from conservative treatment. The remaining 84 (70.59%) children were operated on. Two groups of patients were formed: the comparison group - 38 (45.24%) children, who received traditional treatment, and the main group - 46 (54.76%) children, who were intraoperatively applied anti-adhesive gel to prevent recurrence of postoperative AIO. Results. It was established that postoperative AIO occurred in only 1 (1.19%) child after laparoscopic intervention, in the rest of the children primary surgical interventions were performed by an open method. In the comparative assessment of the postoperative course in two groups of patients, we drew attention to a more favorable course in the children of the main group, which was manifested by a faster recovery of peristalsis, a decrease in the duration of gastric stasis, a faster appearance of independent defecation, and a shorter period of inpatient treatment. When comparing the results of treatment between groups of patients, it was established that the frequency of recurrences of AIO in the main group of patients was 5.44 times lower than in children of the comparison group, and the frequency of relaparotomy for recurrent AIO was 7.28 times lower than in patients of comparison group. We did not observe complications associated with the use of anti-adhesive gel. We did not notice a significant difference in the results of treatment between patients who were treated with anti-adhesive gel of different composition (based on carboxymethylcellulose and sodium hyaluronate). Conclusions. The most effective method of primary prevention of postoperative adhesive intestinal obstruction is the use of laparoscopic primary surgical interventions. Intraoperative application of anti-adhesive gel is a highly effective and safe recurrence prevention method of adhesive intestinal obstruction in children. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Перспективи внутрішньоутробного лікування запальних змін евентрованих органів при гастрошизисі у плодів (огляд літератури)

Gastroschisis (GS) - is one of the most severe defects of newborns, which is characterized by congenital eventration of the abdominal organs outside the anterior abdominal wall into the amniotic fluid, due to a through defect of the anterior abdominal wall. The defect is adjacent to the normal, unaltered umbilical cord, usually to the right of the umbilicus, the umbilical ring is split, the eventrated organs are not covered by embryonic membranes or their remains. The frequency of gastroschisis is 0.31-4.72 per 10,000 births. Although, with the development of modern surgical approaches over the past 15 years, the mortality of newborns with gastroschisisis dynamically decreasing, however, this pathology remains a significant problem in neonatal and pediatric surgery, as it requires early surgery, associated with a significant risk of disability in children due to short bowel syndrome, abdominal cancer and recurrent esophageal disease, adhesive intestinal obstruction, etc. Purpose - to analyze, according to the literature, the prospects for the use of cellular technologies for the in utero treatment of inflammatory changes in the enteric organs in fetal GS in experimental conditions. The main reason for the unsatisfactory results of GS treatment is the pathological changes of the eventrated organs and their consequences. Therefore one of the ways to reduce mortality in GS is intrauterine treatment and the prevention of inflammatory changes of the eventrated organs in the fetuses. Modern regenerative medicine offers several new approaches for the treatment of fetal malformations, including the use of cell technology. Stem cells, from various sources, are one of the alternative therapies that can inhibit inflammatory processes in tissues, activate endogenous reparative mechanisms, and, ultimately, together with the implementation of preventive measures, reduce perinatal mortality and disability. The availability of domestic cell drugs, the development of technologies for their transplantation, and methods of delivery of pregnant women with GS in the fetus, with proven clinical efficacy, will significantly improve the comprehensive treatment of patients with congenital malformations, which is significant social and economic importance. Therefore, the study of regenerative potential and assessment of the prospects for the use of stem cells in obstetrics and perinatal medicine from various sources is of great scientific and practical interest. No conflict of interests was declared by the authors.

Surgical treatment strategy of pulmonary artery sling: a series of 110 cases

Objective: To examine the effect of surgical treatment in children with pulmonary artery sling and the surgical treatment strategy. Methods: Relevant data of 110 children with pulmonary artery sling admitted to the Department of Cardiac Surgery, Children's Hospital Affiliated to Shandong University from February 2017 to July 2022 were retrospectively analyzed. There were 55 males and 55 females, aging (M(IQR)) 9.0 (10.6) months (range: 1 to 96 months). The weight was 7.8 (3.5) kg (range: 2.5 to 25.0 kg). Of the 110 patients, 108 had different degrees of tracheal stenosis and 2 had normal trachea. Left pulmonary artery transplantation and tracheoplasty were performed in 78 patients. Left pulmonary artery transplantation was performed in 30 patients (11 in our hospital and 19 in other hospitals) due to the lack of an early tracheoplasty technique, in which 24 patients needed stage Ⅱ tracheoplasty due to obvious respiratory symptoms and limited activity endurance, and 6 cases did not intervene. Two children with normal trachea only underwent left pulmonary artery transplantation. Results: Among the 78 children who underwent surgery in the same period, 70 cases recovered smoothly after surgery, of whom respiratory symptoms were significantly reduced or disappeared during the 1 to 65 months follow-up, with similar activity endurance to normal children of the same age. Eight cases died, including 4 cases of postoperative multi-drug resistant bacteria infection, died from tracheal anastomotic opening or septic shock, 1 cases with severe congenital heart disease died from postoperative low cardiac output syndrome difficult to correct, 1 case died from blood pressure could not be maintained due to the compressed left pulmonary artery after transplantation, 2 cases of postoperative digestive system diseases (adhesive intestinal obstruction, gastrointestinal bleeding, etc.). The 24 patients in the staging group were followed for 1 to 84 months. All patients needed stage Ⅱ tracheoplasty due to respiratory symptoms and decreased endurance to activity. Eight cases of the non-intervention tracheal group were successfully separated from the ventilator, cured and discharged in a short period of time. Conclusions: Most children with pulmonary artery sling have tracheal stenosis. Children with low degree of tracheal stenosis and inconspicuous respiratory symptoms can only undergo left pulmonary artery transplantation by lateral thoracotomy. For patients combined with severe tracheal stenosis or obvious respiratory symptoms, a simultaneous left pulmonary artery transplantat and tracheoplasty is recommended.

Is laparoscopic surgery safe and feasible in acute adhesive ileus?

Although the classical surgical treatment of adhesive ileus is performed using the open method, laparoscopic surgery has recently been performed in some centers. This study aimed to discuss the feasibility and role of laparoscopic surgery in the treatment of adhesive small bowel obstruction. In this retrospective study, the data of 830 patients who were operated for ileus in Başkent University Faculty of Medicine, Ankara Hospital, Department of General Surgery between January 2011 and September 2022 were analyzed. Missing data and intraabdominal cancer-related ileus were accepted as exclusion criteria and 648 patients were excluded from the study. The development of adhesion-related ileus and completeness of the data were accepted as inclusion criteria. Data were compared between the 2 groups [open group (OG; 152 cases) and laparoscopic group (LG; 30 cases]). When the patient characteristics were evaluated, it was found that the history of previous abdominal surgery (P < .001) and the number of previous abdominal surgery (P < .001) were statistically significantly higher in OG. Operation time was significantly longer in the LG (P = .022). There were no statistically significant differences between the groups in terms of intraoperative bowel injury (P = .216), bowel resection (P = .284), and stoma creation (P = .331). OG had a significantly higher rate of Clavien-Dindo grade ≥ 3 serious complications (P < .001) and mortality rate (P = .045). The first gas out occurred significantly earlier in the LG (P = .014). Oral intake was initiated earlier in the LG (P = .004). The length of hospital stay was significantly shorter in the LG (P < .001). There was no significant difference between the groups in terms of postoperative ileus, readmission, and reoperation. Laparoscopic surgery can be safely performed for the treatment of selected patients with adhesive small bowel obstruction. In addition, it is advantageous in terms of postoperative recovery.

The strategy of laparoscopic surgery for asymptomatic antenatally diagnosed choledochal cyst

BackgroundThe aim was to investigate the characteristics, surgical management, and outcomes of asymptomatic patients with antenatally diagnosed choledochal cysts (ADCCs) and to justify the strategy of laparoscopic surgery (LS) for them in our hospital.MethodsWe developed our LS strategy for asymptomatic ADCCs. Patients with asymptomatic ADCCs who underwent LS or open surgery (OS) during January 2010 and January 2020 were included. Patients with recorded symptomatic ADCCs were exclude. All data of group LS and group OS were statistically compared and analyzed.ResultsTwenty-five patients received LS and 18 patients received OS were included. There was no significant difference in baseline characteristics between the groups. A total of 65.1% of biliary sludge formation was detected preoperatively by ultrasonography (US) (72.0% in group LS, 55.6% in group OS, P = 0.26). Compared to the OS group, the LS group had a longer operative time (313.4 ± 27.2 vs. 154.0 ± 11.9 min, P = 0.02), shorter postoperative fasting period (3.1 ± 1.2 vs. 6.2 ± 2.3 days, P = 0.03), and shorter postoperative hospital stay (5.1 ± 1.9 vs. 9.2 ± 1.1 days, P = 0.03). The incidence of late complications, such as reflux cholangitis, adhesive intestinal obstruction, and biliary enteric anastomotic stricture with stone formation, was not significantly different between the two groups. The liver function and liver stiffness of all patients in the two groups were normal.ConclusionsBased on the strategy for asymptomatic ADCCs in our hospital, the perioperative safety and midterm follow-up results after LS were satisfactory and comparable to those after OS.

Mini-invasive technologies in the treatment of patients with acute adhesion small intestinal obstruction

Modern technologies in surgery lead to an increase in the number of surgical interventions, which in turn increases the number of patients with peritoneal adhesions disease. Patients with acute adhesive small intestinal obstruction make up to 70 %. Acute adhesion small intestinal obstruction takes the leading place among mechanical forms of intestinal obstruction and reaches 63–80 %, and the mortality rate is 5.1–8.4 %.&#x0D; The aim. Improvement of minimally invasive technologies in the treatment of patients with adhesive small intestinal obstruction.&#x0D; Materials and methods. The main group – 99 (58.6 %) patients with adhesions of the small intestine, who underwent minimally invasive treatment technologies. The comparison group included 70 (41.4 %) patients with acute adhesion small intestinal obstruction, who were treated with traditional methods.&#x0D; Results. Based on clinical laboratory and instrumental research results, 21 (12.4 %) patients out of 169 patients underwent emergency surgery: 7 (10.0 %) patients of the comparison group and 14 (14.1 %) patients of the main group. Minimally invasive surgical intervention was performed in 45 (45.5 %) patients of the main group with viscerolysis in 29 (29.3 %) patients and conversion was performed in 16 (16.2 %) patients. Median laparotomy was performed in 54 (54.5 %) patients of the main group and in 70 (100.0 %) patients of the comparison group.&#x0D; The complications of acute adhesive small intestinal obstruction and the complications of the postoperative period in the comparative analysis of the results of the treatment of patients were taken into account. The grading of postoperative complications was carried out in accordance with the classification of P. A. Clavien and D. Dindo (2009), according to which a statistically significant difference is noted in the studied groups: 14 (14.1 %) of the main group and 23 (32.8 %) of the comparison group, III, IV and V degrees of complications were preferred. Relaparotomy was performed in 5 (7.1 %) patients of the comparison group and in 2 (2.0 %) patients of the main group. Mortality decreased from 6 (8.5 %) in the comparison group to 2 (2.0 %) in the main group.&#x0D; Conclusions. The use of an improved approach in diagnostics and treatment of patients with acute adhesion small intestinal obstruction ensured improved results of surgical treatment. The use of mini-invasive technologies in diagnosis and treatment made it possible to reduce the frequency of postoperative complications from 32.8 % to 14.1 %, the mortality rate from 8.5 % to 2.0 %, which confirms the effectiveness of the use of mini-invasive technologies in the treatment of patients with acute adhesion small intestinal obstruction.

Outcomes after staged surgical treatment of children with ileocecal lesions and active extensive inflammation in Crohn’s disease

Introduction. Crohn’s disease is characterized with transmural lesion of the gastrointestinal tract which is frequently localized in the ileocecal region. Despite the achievements in medicamentous therapy, 15–45% of children have to be operated on within 5 years after the diagnosis is verified. Purpose. To substantiate the efficacy of two-stage surgical treatment of children with Crohn’s disease , ileocecal lesion and active extensive inflammation. Material and methods. A single-stage retrospective-prospective study included 43 children with ileocecal lesions and advanced colitis. Two-stage surgical treatment was performed. In the preoperative period, the following parameters were assessed: physical state, clinical activity, anemia and the level of hypoalbuminemia as well as inflammation markers, findings at endoscopy and MRI. Indications for surgical treatment were strictures in the ileocecal region, endoscopic and clinical activity and colon lesion and / or purulent-septic lesions in the perianal region. 39 (90.7 %) children had laparoscopically-assisted surgeries. 4 (9.3 %) children underwent conversions due to a pronounced infiltrative process in the abdominal cavity. Results. Lengths of hospitalization for children with stoma varied from 5 to 20 months (median 8 months). PCDAI index: in 25 (57.8 %) high activity, in 18 (41.2 %) moderate activity. After surgical intervention: 7 (16.2%) children had mild course, 36 children (p 0.05) SES-CD before surgery – all children had high endoscopic activity. In the postoperative period by Rutgeerts scale findings, there was a statistically significant positive dynamics (p = 0.011). Anthropometric parameters (HAZ p 0.05; BAZ p 0.001) and laboratory findings (p 0.001) were statistically significant for positive dynamics too.In the postoperative period: 5 (11.6 %) children developed ligature fistulas; 2 children (4.6 %) had narrowed intestinal anastomosis without passage disorders; 2 (4.6 %) children developed acute adhesive intestinal obstruction. In foreign and Russian publications, postoperative complications were reported in 6 % to 29 %. Conclusions. Crohn’s disease has led to chronic anemia, hypoalbuminemia, chronic bacterial inflammation, reduced physical growth and worsen quality of life. After the two-stage surgical treatment, the statistical analysis demonstrated a significant improvement in mass-growth, laboratory and endoscopic parameters.

Systematic Review of the Clinical Efficacy of Various Terms of Non-Surgical Treatment in Patients With Acute Adhesive Intestinal Obstruction

BACKGROUND The question of the duration and volume of conservative measures in patients with acute adhesive intestinal obstruction (AAIO) remains the subject of numerous discussions. Aim of study To evaluate the efficacy and safety of various periods of conservative therapy in patients with AAIO using a systematic review. MATERIAL AND METHODS Criteria for inclusion in the systematic review were cohort studies investigating various regimens and duration of conservative therapy in adult patients with AAIO. The search for primary sources was carried out in the CENTRAL, PubMed and eLibrary databases. The assessment of the safety of various terms of AAIO was carried out by comparing the immediate results of treatment. RESULTS The review included 19 papers with a total of 2,570 observations. At the first stage, the effectiveness of various conservative therapy regimens was evaluated by calculating the risk ratio for the success of non-surgical treatment. Taking into account the significant statistical heterogeneity of the participants, the calculation of the final risk ratio was carried out using a random effects model. The hazard ratio for nonoperative success was 1.91 (95% CI 1.2–3.1) in favor of gastrografin and 3.71 (95% CI 1.3–10.6) in favor of preoperative intestinal intubation. Taking into account the multidirectional pathogenetic action of the studied methods of conservative therapy, the obtained results suggested that the probability of success of non-surgical treatment correlates to a greater extent with the total duration of the AAIO episode than with the duration of conservative therapy, which was indirectly confirmed by constructing scattering graphs with approximation lines and calculating the coefficients determination, which amounted to 0.69 and 0.77 for the subgroups of standard therapy and undiluted gastrografin, respectively. Subsequently, the impact of different duration of an episode of AAIO on the immediate outcomes was assessed: mortality, frequency of resection interventions, complications, and total bed-day. There were no statistically significant differences in favor of early interventions (up to 48 hours) for all compared parameters; an increase in the total duration of AAIO up to 89 hours was not associated with worse results. CONCLUSION The total duration of the episode of acute adhesive intestinal obstruction, including both the pre-hospital duration and the duration of non-surgical treatment is prognostically significant. In other words, when calculating the allowable duration of conservative measures, one should proceed from the total duration of intestinal passage disturbance, which should not exceed 89 hours.

Evaluation of Role of Laparoscopy in Treatment of Acute Adhesive Intestinal Obstruction

Evaluation of Role of Laparoscopy in Treatment of Acute Adhesive Intestinal Obstruction

Peritoneal dialysis-related peritonitis with encapsulated ascites due to Mycobacterium abscessus subsp. massilience and subsp. bolletii: a case series and literature review

BackgroundAs there is no established standard of care for non-tuberculous mycobacterium (NTM) peritoneal dialysis (PD)-related peritonitis, its treatments have to be case-dependent, which is often difficult. Additionally, several reported cases were accompanied by encapsulated ascites, adhesive ileus, and encapsulating peritoneal sclerosis, suggesting treatment difficulties. We report two cases of PD-related peritonitis with encapsulated ascites due to Mycobacterium abscessus subsp. massilience and subsp. bolletii. To the best of our knowledge, this is the first case series to report PD-related peritonitis caused by Mycobacterium abscessus subsp. bolletii.Case presentationThe first case is that of a 74-year-old male patient who started PD six years ago for end-stage renal failure due to diabetic nephropathy. In February 2021, he presented with signs of infection at the exit-site and swelling of the tunnel. Mycobacterium abscessus subsp. massilience was detected in the culture of the exit-site exudate; thus, he was diagnosed with tunnel infection (caused by NTM). Subsequently, fever, abdominal pain, and increased cell counts in the PD drainage fluid were observed, and he was judged to have NTM peritonitis. His general condition improved after PD catheter removal in addition to antimicrobial treatment and encapsulated ascites drainage. The second case is that of a 52-year-old man who commenced PD for end-stage renal failure due to nephrosclerosis 12 years ago. In May 2022, he was diagnosed with PD-related peritonitis based on signs of infection at the exit-site, encapsulated ascites on computed tomography, and a cloudy PD drainage fluid. Mycobacterium abscessus subsp. bolletii was detected in the culture of the exit-site exudate, which led to the diagnosis of NTM peritonitis. In addition to antimicrobial treatment, PD catheter removal and encapsulated ascites drainage were performed. The patient also had adhesive bowel obstruction due to peritonitis and required decompression therapy with the insertion of a gastric tube.ConclusionsPD catheter removal and encapsulated ascites drainage might have improved inflammation and treatment outcomes. Additionally, Mycobacterium abscessus might be prone to forming encapsulated cavities and/or intestinal adhesions; however, further accumulation of cases clarifying “subspecies” of Mycobacterium abscessus is necessary to confirm this hypothesis.

Surgical disconnection of high delineated immature debilitating jejunal fistulas using posterolateral access

Objective. The aim of the study was to develop the safest technique for surgical disconnection of high, unformed jejunal fistulas, so as to avoid problems with detection the intestine leading to the fistula and to avoid complications of viscerolysis. Material and methods. The authors present their experience in surgical management of 35 patients with high delimited unformed debilitating jejunal fistulas. Of these, 22 patients were included in the comparison group; their fistulas were closed or disconnected with the known methods. Findings obtained from other 172 patients with adhesive intestinal obstruction after infectious complications of laparotomic wounds and topography of visceroparietal planar adhesions of the peritoneum were analyzed. After studying the nature and location of visceroparietal adhesions, the authors could develop a technique for proximal disconnection of high delimited unformed debilitating jejunal fistulas using posterolateral access which was applied in 13 patients from the studied group. Research results. The proposed technique of unilateral disconnection of high unformed jejunal fistulas reduces duration, damage and risk of prolonged bowel deserosing. As a result, a significant decrease in postoperative mortality from 59.1 ± 9.2% to 23.1 ± 11.2% (t=2.5; p&lt;0.05) was registered. Due to the preoperative endoscopic marking showing direction to the fistula of intestinal loop and duodenojejunal junction, intraoperative orientation was more accurate and took much less time than in the comparison group. The posterolateral surgical approach to the fistula in the jejunal loop reduced the risk of its damage, since there was no need for extensive enterolysis anymore. Therefore, postoperative period in patients of the studied group was better and with fewer complications than in the comparison group. Conclusion. The posterolateral access prevented extended viscerolysis and allowed to put a reliable and atraumatic interintestinal anastomosis so as to disconnect the fistula. The unilateral disconnection of the jejunal fistula at postoperative intestinal paresis unloaded the interintestinal anastomosis, similar to Meidl’s definitive jejunostomy. The abovementioned positive aspects of the proposed surgical intervention allowed to significantly decrease postoperative complications and mortality rate, if to compare with outcomes after known surgical interventions with a similar purpose.

ACUTE DESTRUCTIVE PANCREATITIS IN CHILDREN

Unlike adults, acute pancreatitis in children is a rare disease. The absence of unified standards for the diagnosis, treatment and rehabilitation of children with acute destructive pancreatitis, as well as high rates of complications and mortality, determined the relevance of our study.Materials and methods. Materials and methods. The results of treatment of 11 children with acute destructive pancreatitis were studied. The age of the patients ranged from 2 to 16 years. Laboratory examination in all patients included general and biochemical analyzes of blood, urine, peritoneal and thoracic exudate. All children underwent an ultrasound examination of the abdomen, chest cavity and mediastinum, and plain radiography of the chest and abdominal cavity. Computed tomography was performed in 6 patients (54.5%). Fibrogastroduodenoscopy (FGDS) was performed in 3 patients (27.3%). All patients underwent surgery. In 8 cases (72.7%), a median laparotomy was performed initially. In 3 observations (27.3%), surgical treatment began with video surgical revision of the abdominal organs, and then switched to conversion. Three patients (27.3%) subsequently underwent cystopancreatic jejunostomy. In one child, transcutaneous drainage of a false pancreatic cyst was performed under video surgical control. Synthetic somatostatin analogs and proteinase inhibitors were used as targeted therapy. All patients received long-term antibacterial therapy. Various methods of extracorporeal detoxification were used in 6 patients (54.5%).Statistical processing of the research results was carried out using standard methods with the calculation of relative values (absolute number of observations, % ratio).The approval of the scientific work was received from the Bioethical Commission of the Donetsk National Medical University (Ukraine).The work is a fragment of proactive research work of the Department of General and Children's Surgery of the Donetsk National Medical University (Ukraine). Results. Complications in the early postoperative period were noted in 8 children (72.7%). The group of the most severe complications included progressive enzymatic bacterial peritonitis, early adhesive intestinal obstruction, failure of cystopancreatic ileal anastomosis, profuse arrosive hemorrhage from the pancreas, cystopancreaticodigestive fistula and eventation. In the early postoperative period, 1 child aged 14 years (9.1%) died, and the rest of the patients were discharged in satisfactory condition. The average hospital stay for children was 23.1 days. In 7 patients (63.6%), complaints characterized by "enteric" discomfort occurred later.Conclusions. The principles of surgical and therapeutic tactics in children with acute destructive pancreatitis are based on a differentiated approach depending on the form of pancreatic necrosis and the development of purulent and destructive complications. Further study requires determination of situational surgical tactics, assessment of the effectiveness of combined therapy with somatostatin and proteinase inhibitors, selection of the optimal regimen of nutritional therapy and rehabilitation.

Morphofunctional changes in the small intestine in acute adhesive small bowel obstruction

Aim: To study the features of morpho-functional changes in the small intestine mucosa in acute adhesive small bowel obstruction.Material and methods. The results of a comprehensive study of morphological and functional changes in the small intestine’s mucous membrane in 20 patients out of 50 with acute adhesive small intestinal obstruction were analyzed. Patients underwent resection of the small intestine with a biopsy from the mucous membrane, followed by a pathomorphological and biochemical examination of biopsy specimens.Results. The study results show that more pronounced pathomorphological changes in the mucous membrane of the small intestine were observed in patients with acute adhesive small intestinal obstruction with widespread (multiple) adhesions compared with limited (single) adhesions. In the study of biochemical parameters in the small intestine mucosa in patients with acute adhesive small intestinal obstruction with the presence of multiple (widespread) adhesions, there was a significant and critical increase in lipid peroxidation and proinflammatory cytokines, a decrease in antioxidant protection compared to the patient group with the presence of single (limited) adhesions. There was also a decrease in the concentration of serotonin in the mucosa of the small intestine. In the presence of single (limited) adhesions in these patients, it decreases to 0,50±0,3 units, and in patients with multiple (common) adhesions - to 0,20±0,2 arb. units.Conclusion. The severity of morpho-functional changes in the mucosa of the small intestine directly correlates with the severity of the development of the adhesive process and acute adhesive small bowel obstruction.
