Increased Risk of Meconium-Related Ileus in Extremely Premature Infants Exposed to Antenatal Magnesium Sulfate

Introduction: We experienced an increased incidence of meconium-related ileus (MRI) in extremely premature infants (EPIs) while adopting the antenatal magnesium sulfate (MgSO4) protocol for fetal neuroprotection in our neonatal intensive care unit. This study aimed to test whether antenatal MgSO4 use was associated with increased risk of MRI in EPIs. Methods: The incidences of complicated MRI requiring aggressive enema or surgical intervention and other intestinal complications were compared among period 1 (January 2012–December 2013, n = 79), before adoption of the antenatal MgSO4 protocol for fetal neuroprotection; period 2 (January 2014–March 2016, n = 72), when the protocol was adopted; and period 3 (April 2016–September 2018, n = 75), when the protocol was temporarily withdrawn due to concern regarding intestinal complications in EPIs. Results: Despite similar baseline clinical characteristics among infants across the study periods, the MRI and MRI with surgical treatment incidences were higher in period 2 than those in periods 1 and 3 (13% vs. 8% and 6%, p = 0.391, and 11% vs. 0% and 1%, p = 0.001, respectively). In multivariable analysis, exposure to antenatal MgSO4 independently increased the risk of MRI (adjusted odds ratio, 3.8; 95% confidence interval, 1.4, 10.6). Conclusion: Antenatal MgSO4 may increase the risk of MRI, frequently requiring surgical intervention, in EPIs with a gestational age of 25 weeks or less.

External iliac artery extension causes greater aneurysm sac regression than the bell-bottom technique or iliac branch endoprosthesis for repair of concomitant infrarenal aortic and iliac artery aneurysm

ObjectiveAneurysmal extension of abdominal aortic aneurysms (AAAs) to the common iliac artery (CIA) presents a technical challenge to successful endovascular abdominal aortic aneurysm repair (EVAR). In the present study, we compared sac shrinkage and perioperative outcomes after the bell-bottom technique (BBT), internal iliac artery embolization and external iliac artery extension (EIE), and iliac branch endoprosthesis (IBE). MethodsUsing the Vascular Quality Initiative database, a retrospective analysis was conducted for patients who had undergone EVAR from 2013 to 2019. The demographic, anatomic, and perioperative data were analyzed. All patients with a proximal aortic neck length <10 mm and aortic graft diameter >32 mm were excluded from the analysis. The patients were subdivided into four groups according to the distal limb strategy: group 1, control group with a bilateral common iliac artery limb <20 mm; group 2, BBT with either a unilateral or bilateral limb >20 mm; group 3, EIE technique; and group 4, IBE. The primary endpoint was the maximal change in the aortic diameter during follow-up. The secondary endpoints included postoperative complications and the rate of endoleak. ResultsThe records for 14,455 patients who had undergone EVAR were queried and 5788 met the anatomic criteria. The average age was 73 years, and 86.3% were men. The maximal change in the aortic diameter in the control, BBT, IBE, and EIE groups was −7.2 mm, −6.1 mm, −4.6 mm, and −6.8 mm, respectively (P = .06). The differences were not statistically significant on univariate analysis at an average follow-up of 405 days. However, on multivariable analysis (P = .01), compared with the control group, the BBT and IBE groups were 18.4% (odds ratio [OR], 0.816; 95% confidence interval [CI], 0.68-0.98) and 48.0% (OR, 0.52; 95% CI, 0.33-0.82) less likely to experience aneurysmal shrinkage, respectively. In contrast, the EIE group showed no significant difference in shrinkage compared with that in the control group. Multivariable analysis of the groups also revealed that compared directly with the BBT group, the EIE group was 69.5% more likely to have experienced shrinkage in the aortic aneurysmal diameter (OR, 1.70; 95% CI, 1.05-2.75). The BBT and IBE groups had a significantly higher rate of type II endoleaks (17.63% and 16.95%, respectively; P = .03). The EIE group had a higher rate of type Ib endoleaks (1.9%) compared with the BBT (1.1%), IBE (1.7%), and control (0.3%) groups (P = .01). No differences were found between the groups in terms of postoperative myocardial infarction (P = .47) or respiratory (P = .61) or intestinal (P = .71) complications. However, the rates of limb complications and reoperation were higher in the EIE group. ConclusionsThe present study revealed that the EIE technique was more likely to demonstrate shrinkage in the aortic aneurysmal diameter than were the BBT and IBE groups compared with the control group on multivariable analysis. The EIE technique was also more likely to result in aneurysmal sac shrinkage than was the BBT group, albeit with greater rates of limb-related complications.

Role of Vitamin K in Intestinal Health.

Intestinal diseases, such as inflammatory bowel diseases (IBDs) and colorectal cancer (CRC) generally characterized by clinical symptoms, including malabsorption, intestinal dysfunction, injury, and microbiome imbalance, as well as certain secondary intestinal disease complications, continue to be serious public health problems worldwide. The role of vitamin K (VK) on intestinal health has drawn growing interest in recent years. In addition to its role in blood coagulation and bone health, several investigations continue to explore the role of VK as an emerging novel biological compound with the potential function of improving intestinal health. This study aims to present a thorough review on the bacterial sources, intestinal absorption, uptake of VK, and VK deficiency in patients with intestinal diseases, with emphasis on the effect of VK supplementation on immunity, anti-inflammation, intestinal microbes and its metabolites, antioxidation, and coagulation, and promoting epithelial development. Besides, VK-dependent proteins (VKDPs) are another crucial mechanism for VK to exert a gastroprotection role for their functions of anti-inflammation, immunomodulation, and anti-tumorigenesis. In summary, published studies preliminarily show that VK presents a beneficial effect on intestinal health and may be used as a therapeutic drug to prevent/treat intestinal diseases, but the specific mechanism of VK in intestinal health has yet to be elucidated.

Incidence of late severe intestinal complications after bowel atresia/stenosis.

To determine the incidence and risk factors for late severe intestinal complications after surgical repair for intra-abdominal congenital intestinal atresia/stenosis. We included 51 patients who underwent surgical repair for congenital intestinal atresia/stenosis. Late severe intestinal complications included adhesive ileus, incisional hernia, or volvulus. Whether surgical intervention was urgent or not was recorded. The location of the atresia/stenosis was classified into two groups: atresia/stenosis located at the oral or anal side from the Treitz ligament. The type of atresia/stenosis was classified as low-risk types (type I, mucosal web/II, fibrous cord/IIIa, mesenteric gap defect) and high-risk types (IIIb, apple peel/IV, multiple atresia). We compared the incidence of late intestinal complications between the location of intestinal atresia/stenosis at the oral and anal side of Treitz ligament, and between low- and high-risk types of atresia/stenosis using Fisher's exact test. Eight (15.7%) had late intestinal complications, all of which occurred in patients with intestinal atresia/stenosis located on the anal side of the ligament of Treitz. Urgent surgical intervention was needed in four cases. There was a significant difference in the location of atresia/stenosis (with vs. without late intestinal complications at oral/anal side of the Treitz ligament: 0/8 vs. 24/19; P = 0.005) and the type of intestinal atresia/stenosis (with vs. without that accompanying low-/high-risk type: 5/3 vs. 41/2; P = 0.023). Physicians should consider the presence of intestinal complications that require surgical intervention in patients undergoing surgical reconstruction for jejunal and ileal atresia/stenosis with abdominal symptoms.

Pancreas Transplantation with Duodeno-Duodenal Anastomosis: A Single-Center Experience

Introduction: Techniques such as retroperitoneal graft placement have further improved the ability to reproduce the physiology of the “native” pancreas. We herein present our experience of a technique for pancreatic transplant, with the organ placed into a fully retroperitoneal position with systemic venous and enteric drainage of the graft by duodenoduodenostomy. Methods: All pancreas transplantations performed between May 2016 and July 2021 were prospectively entered into our transplant database and retrospectively analyzed. Results: A total of 81 transplants were performed using the duodenoduodenostomy (43 men: median age of 42 years [IQR 36-50]). Median cold ischemia times was 9 hours [IQR 7-10.4]. The preservation solution used was Celsior (n=19), IGL-1 (n=49), and UW (n=13). Regarding morbidity, 43.2% of patients presented pancreas related complications: abdominal hemorrhage (n=8, 9.9%); graft pancreatitis (n=5, 6.2%); fluid collections (n=9, 11.1%); and vascular thrombosis (n=20, 24.7%). Intestinal complications (n=7, 8.6%) were: intestinal obstruction (n=2); paralytic ileus (n=2); dehiscence in duodenum after pancreas transplantectomy (n=1); dehiscence of duodeno-duodenostomy (n=2). Of these, four cases required relaparotomy: adhesiolysis (n=2); transplantectomy (n=1); primary leak closure (n=1). According to the Clavien-Dindo classification, pancreas complications were: Grade I: 3.7 %, Grade-II: 13.6 %, and Grade IIIa:4.9%, Grade IIIb: 21%. The median hospital stay was 13.5 days. After a median follow-up of 30.7 months [IQR 18.1-44], the 1 and 3-year graft survival was 89.5%, respectively, with no patient mortality. Conclusions: Retroperitoneal graft placement with duodenoduodenostomy is safe and feasible, with a low rate of intra-abdominal complications, providing competitive results in terms of graft/patient survival.

Prevalence of Salmonella typhi in among febrile patients in a tertiary care hospital of South West Rajasthan.

ABSTRACTBackground:Salmonella enterica, serotype typhi, remains the predominant Salmonella species causing enteric fever in India. The mode of Salmonella typhi transmission is considered to be predominantly vehicle-borne through contaminated water or food. In India, the incidence of Salmonella typhi occurs between the months of April and June (dry season) followed by July and September (monsoon season). Typhoid fever may be difficult to distinguish clinically from other febrile illnesses and if left untreated, intestinal, neuropsychiatric, and other complications develop in some patients.Objective:The aim of this study was to determine the prevalence of S. typhi in bloodstream infections and its antimicrobial susceptibility pattern among patients with febrile illness.Methodology:Febrile patients admitted in the hospital who were prescribed blood culture tests and whose samples were sent to microbiology laboratory were included in the study. All blood samples (average 5 mL for adults and 2–3 mL for pediatric age group) were immediately inoculated into Bac-T ALERT aerobic blood culture bottles containing sodium polyethanol sulfonate as an anticoagulant (0.025%). If growth was isolated, isolated colony characteristics of growth and Gram stain were assessed. On Gram staining, typical nonlactose fermenting Gram negative bacilli were further subjected to species identification and detection of antimicrobial susceptibility pattern on the VITEK2.Results:In this study period, a total of 511 blood culture (paired) samples were processed, out of which 47 isolates of Salmonella were obtained. Among these isolates, 33 (70.23%) were from males, and 14 (29.77%) were from females. Amongst these, 35 (74.4%) patients were from rural, 8 (17%) were from subrural, and 4 (8.5%) were from urban areas. Out of the total 47 isolates of Salmonella, 42 (89.36%) were Salmonella typhi, 2 (4.25%) were Salmonella paratyphi A and B each, and 1 (2.12%) was Salmonella enterica. Antimicrobial susceptibility pattern of Salmonella isolates revealed that all the isolates of Salmonella species were highly susceptible (95%–100%) to third generation cephalosporins (ceftazidime, ceftriaxone, cefepime, cefoperazone-sulbactam) and other higher antibiotics such as betalactamase inhibitors – piperacillin tazobactam (95%–100%) and Ticarcillin–clavulanic acid (100%). They were also highly susceptible (100%) to carbapenams (imipenem, merpenem, doripenem, and ertapenem) but showed a fairly decreased susceptibility was towards nalidixic acid with 15% for Salmonella typhi and 50% for other Salmonella isolates.Conclusion:Surging drug-resistant Salmonella enterica cases, the level of resistance was not as high as predicted in our study population. Multidrug-resistant (MDR) trends may vary; therefore, drug susceptibility testing side-by-side to empirical therapy is mandatory, especially in developing countries where there is a practice of self-medication.

Cerebrovascular Events in Pediatric Inflammatory Bowel Disease: A Review of Published Cases.

Pediatric inflammatory bowel disease (PIBD) is a multisystem disorder characterized by intestinal and extraintestinal manifestations and complications. Cerebrovascular events (CVE) are rare extraintestinal complications in patients with PIBD. Statistics show that 3.3% patients with PIBD and 1.3–6.4% adult patients with inflammatory bowel disease (IBD) experience CVE during the course of the disease. Therefore, this study aimed to review the records of children with IBD who developed CVE during the course of the disease. We retrospectively reviewed 62 cases of PIBD complicated by CVE. The mean patient age at the time of thrombotic events was 12.48±4.13 years. The incidence of ulcerative colitis was significantly higher than that of Crohn’s disease (43 [70.5%] vs. 13 [21.3%] patients). Most patients (87.93%) were in the active phase of IBD at the time of CVE. The mean time interval between the onset of IBD and CVE was 20.84 weeks. Overall, 11 (26.83%) patients showed neurological symptoms of CVE at disease onset. The most frequent symptom on admission was persistent and severe headaches (67.85%). The most common site of cerebral venous thrombosis was the transverse sinuses (n=23, 53.48%). The right middle cerebral artery (n=3, 33.34%) was the predominant site of cerebral arterial infarction. Overall, 41 (69.49%) patients who were mostly administered unfractionated heparin or low-molecular-weight heparin (56.09%) recovered completely. Patients with IBD are at a risk of thromboembolism. CVE may be the most common type of thromboembolism. Based on these findings, the most common risk factor for CVE is IBD flares. In patients with CVE, anticoagulant therapy with heparin, followed by warfarin, is necessary.

Transabdominal Ultrasound and Magnetic Resonance Enterography in Inflammatory Bowel Disease: Results of an Observational Retrospective Single-Center Study.

Purpose Transabdominal ultrasound (US) and magnetic resonance enterography (MRE) are used to assess disease activity and extent in IBD, but their impact on therapeutic decisions is unclear. Therefore, our study has two goals: to compare the usefulness of US and MRE in assessing disease extent and activity in the small and large bowel, and to determine the relevance for clinical decisions in IBD. Materials and Methods We included 54 IBD patients who had undergone both MRE and US within three months. We used the construct reference standard model to compare MRE and US for detecting inflammation and examined the impact on clinical decisions in IBD patients. Results In 54 IBD patients (44 patients Crohn’s disease (CD), 5 ulcerative colitis (UC), 5 indeterminate colitis (IC)), 42 patients (77.8%) showed inflammation either in the small or large bowel. Small bowel disease was present in 34 patients (77.3%). Complications were found in 19 patients (35.2%). MRE and US both showed high sensitivity (90.5 and 88.1%) and moderate specificity (50% in MRE and US) for detecting inflammation. MRE revealed higher sensitivity than US for detecting conglomerate tumors without statistical significance (85.7 vs. 71.4%, p=1.0) and equal specificity (97.9 vs 97.7, p=1.0). Therapeutic decisions included steroids in 20 patients (47.6%) and surgery/percutaneous drainage in six patients (14.3%), these decisions were triggered by results of US or MRE in equal distribution. Conclusion US and MRE have comparable sensitivity and specificity for detecting intestinal inflammation and complications in IBD patients. Therefore, both methods are sufficient for making clinical decisions.

新型コロナウイルス感染症（COVID–19）に伴う難治性大量下痢症の1例(A case of refractory massive diarrhea in a patient with COVID–19)

ABSTRACTThe new coronavirus disease (COVID–19) causes gastrointestinal symptoms as well as respiratory symptoms. We report a case of massive refractory diarrhea from the perspective of gut microbiota. A 60–year–old man was transferred with dyspnea. He was diagnosed as having COVID–19 and was intubated on mechanical ventilation with extracorporeal membrane oxygenation. He was administered anti–viral drug therapy and antibiotics. He suffered from diarrhea from day 12 and produced a maximum of about 6,384mL/day of watery diarrhea on day 21. He required massive transfusion and catecholamines for circulatory support. Adsorbents, pectin–containing oligomeric formulas and synbiotics were administered, which decreased the amounts of diarrhea. After day 30, the amount of diarrhea decreased to less than 1,000mL/day. Fecal metagenomic analysis showed the proportions of Enterococcus and Staphylococcus in the phylum Firmicutes were the most dominate at the genus level. The proportion of Bacteroidetes was less than 1%, and the gut microbiota had dramatically changed. Thereafter, his diarrhea decreased to occasional instances, and he was transferred to another ward on day 104. Therapy for intestinal complications might be important in treating COVID–19. Intestinal therapy such as adsorbents might be effective in patients with massive diarrhea.

Terminal Ileal Bleed as Intestinal Complication of Enteric Fever – Symptomatic Management

Terminal Ileal Bleed as Intestinal Complication of Enteric Fever – Symptomatic Management

Intestinal complications are common in patients with acquired diaphragmatic hernia after pediatric living donor liver transplantation

Acquired diaphragmatic hernia (DH) following liver transplantation (LT) is usually considered a surgical emergency. Interplay of contributing elements determines its occurrence but, in children, LT with partial liver grafts seems to be the most important causative factor. This retrospective study describes the clinical scenario and outcomes of 11 patients with acquired DH following LDLT. During the study period, 1109 primary pediatric LDLT were performed (0.8% DH). The median age and BW of the recipients with DH at transplantation were 17months and 11.1kg, respectively; 63.7% of the cases had a weight/age Z-score of less than -2 at transplantation. The median interval between transplantation and diagnosis of DH was 114days (32-538days). A total of 6 (54.5%) of the patients had bowel obstruction due to bowel migration into the hemithorax. Ten defects were right-sided. Three patients required enterectomy and enterorrhaphy. Two patients required a new bilioenteric anastomosis, and one of them had complete necrosis of the Roux-in-Y limb. The patient with left-side DH presented gastroesophageal perforation. Most defects necessitate primary closure as the first treatment, and recurrence is rare. The associated problems encountered, especially related to intestinal complications, can determine increased morbidity following DH repair. Early diagnosis and intervention are required for achieving better outcomes.

Current Topics of the Mechanism of Intestinal Fibrosis in Crohn’s Disease

Intestinal fibrosis is one of the most common intestinal complications observed in inflammatory bowel disease, especially Crohn’s disease (CD). Intestinal fibrosis in CD is associated with chronic inflammation resulting from immunologic abnormalities and occurs as a form of tissue repair during the anti-inflammatory process. Various types of immune cells and mesenchymal cells, including myofibroblasts, are intricately involved in causing intestinal fibrosis. It is often difficult to treat intestinal fibrosis as intestinal stricture may develop despite treatment aimed at controlling inflammation. Detailed analysis of the pathogenesis of intestinal fibrosis is critical towards advancing the development of future therapeutic applications.

Nonalcoholic fatty liver disease is associated with worse intestinal complications in patients hospitalized for Clostridioides difficile infection.

BACKGROUNDNonalcoholic fatty liver disease (NAFLD) has become the leading cause of chronic liver disease with increasing prevalence worldwide. Clostridioides difficile infection (CDI) remains the most common cause of nosocomial diarrhea in developed countries. AIMTo assess the impact of NAFLD on the outcomes of hospitalized patients with CDI.METHODSThis study was a retrospective cohort study. The Nationwide Inpatient Sample database was used to identify a total of 7239 adults admitted as inpatients with a primary diagnosis of CDI and coexisting NAFLD diagnosis from 2010 to 2014 using ICD-9 codes. Patients with CDI and coexisting NAFLD were compared to those with CDI and coexisting alcoholic liver disease (ALD) and viral liver disease (VLD), individually. Primary outcomes included mortality, length of stay, and total hospitalization charges. Secondary outcomes were in-hospital complications. Multivariate regression was used for outcome analysis after adjusting for possible confounders. RESULTSCDI with NAFLD was independently associated with lower rates of acute respiratory failure (2.7% vs 4.2%, P < 0.01; 2.7% vs 4.2%, P < 0.05), shorter length of stay (days) (5.75 ± 0.16 vs 6.77 ± 0.15, P < 0.001; 5.75 ± 0.16 vs 6.84 ± 0.23, P <0.001), and lower hospitalization charges (dollars) (38150.34 ± 1757.01 vs 46326.72 ± 1809.82, P < 0.001; 38150.34 ± 1757.01 vs 44641.74 ± 1660.66, P < 0.001) when compared to CDI with VLD and CDI with ALD, respectively. CDI with NAFLD was associated with a lower rate of acute kidney injury (13.0% vs 17.2%, P < 0.01), but a higher rate of intestinal perforation (P < 0.01) when compared to VLD. A lower rate of mortality (0.8% vs 2.7%, P < 0.05) but a higher rate of intestinal obstruction (4.6% vs 2.2%, P = 0.001) was also observed when comparing CDI with NAFLD to ALD.CONCLUSIONHospitalized CDI patients with NAFLD had more intestinal complications compared to CDI patients with VLD and ALD. Gut microbiota dysbiosis may contribute to the pathogenesis of intestinal complications.

Intestinal Complication With Myxomatous Mitral Valve Diseases in Chihuahuas.

The effects of cardiac disease on the intestine have been reported in humans but not in dogs. We investigated the effects of myxomatous mitral valve disease (MMVD), which is capable of causing congestion and tissue hypoperfusion, on the intestine in Chihuahuas, a breed frequently encountered in clinical practice as the preferred breed for MMVD. In this study, 69 Chihuahuas were divided into four groups based on echocardiography and chest radiography: 19 healthy Chihuahuas (H) and 50 Chihuahuas with MMVD classified according to the ACVIM consensus (stage B1, B2, C/D). In all the cases, serum intestinal fatty acid-binding protein (I-FABP) and D/L-lactate concentrations, markers of intestinal mucosal injury, were measured. I-FABP was significantly higher in stage C/D Chihuahuas than in other groups (p < 0.05), and stage B2 was significantly higher than H (p < 0.05). D-lactate was significantly increased in stages B2 and C/D compared to H and stage B1 (p < 0.05). L-lactate was significantly higher in stage C/D Chihuahuas than in any other group (p < 0.05), and stage B2 was significantly higher than that in H and stage B1 (p < 0.05). Intestinal mucosal injury risk was significantly higher in Chihuahuas with heart failure due to MMVD, suggesting that the risk could increase with worsening heart disease. This is the first study to investigate the intestinal complications of MMVD, and further investigations a needed in the future.

Comparative study of CT relative enhancement value and subjective visual evaluation for intestinal ischemia in patients with closed loop obstruction

Objective: To compare and evaluate the diagnostic performance of visual evaluation and CT maximal density relative enhancement value in the diagnosis of intestinal ischemia complication in patients with closed loop obstruction and to explore the feasibility of CT maximal density relative enhancement value in quantifying the degrees of intestinal ischemia. Methods: The clinical and CT imaging data of 82 patients, 46 males and 36 females, aged from 19 to 78(52±18) years, with closed loop obstruction were retrospectively analyzed in the First Affiliated Hospital of Zhengzhou University from July 2017 to July 2019. All patients were classified into three groups: necrosis group (28 cases), ischemia group (22 cases), non-ischemia group(32 cases) using clinicopathologic results as reference standard. CT visual evaluation was performed by two experienced radiologists. The sensitivity, specificity, positive and negative predictive values and accuracy of the two observers were calculated respectively. The inter-observer agreement was analyzed by kappa analysis. Maximal density relative enhancement value was defined as the difference CT value of an ROI at dilated obstructed loops between contrast-enhanced and unenhanced CT images. The differences among groups were compared by one-way analysis of variance. Diagnostic performances were evaluated by receiver operating characteristic (ROC) curve analysis. Results: The sensitivity, specificity, positive and negative predictive values and accuracy of observer1 were 62.0%, 87.5%, 88.6%, 59.6%, 72.0%, and 58.0%, 93.8%, 93.5%, 58.8%, 72.0%for observer2, respectively. The kappa value of inter-observer agreement was 0.747. The unenhanced CT value of necrosis group, ischemia group and non-ischemia group was (53.7±9.7), (45.7±7.2) and (44.7±7.0) HU, enhanced CT value was (60.5±10.1), (65.0±11.6) and (87.0±15.8) HU, relative enhancement value was(6.8±8.4), (19.2±12.4) and(44.7±16.2)HU, respectively. All had a statistical difference among three groups (all P<0.05). The unenhanced CT value of necrosis group was higher than that of ischemia group and un-ischemia group (both P<0.05). The enhanced CT value of non-ischemia group was higher than that of ischemia group and necrosis (both P<0.05). The relative enhancement value all had a significant difference between groups (all P<0.05). Taking maximal density relative enhancement value below 19.5 HU as diagnosis threshold, the sensitivity, specificity and area under curve(AUC) were 96.9%, 74.0% and 0.947, respectively. Taking enhanced CT value below 66.5 HU as diagnosis threshold, the sensitivity, specificity and AUC were 93.8%, 60.0% and 0.903, respectively; the sensitivity was higher than that of objective visual evaluation. Conclusion: Maximal density relative enhancement value can quantize the bowel wall enhancement, and is a more reliable way in the diagnosis of intestinal ischemia than visual evaluation.

Ultrasound Markers for Complex Gastroschisis: A Systematic Review and Meta-Analysis.

Although gastroschisis is often diagnosed by prenatal ultrasound, there is still a gap in the literature about which prenatal ultrasound markers can predict complex gastroschisis. This systematic review and meta-analysis aimed to investigate the ultrasound markers that characterize complex gastroschisis. A systematic review of the literature was conducted according to the guidelines of PRISMA. The protocol was registered (PROSPERO ID CRD42020211685). Meta-analysis was displayed graphically on Forest plots, which estimate prevalence rates and risk ratios, with 95% confidence intervals, using STATA version 15.0. The combined prevalence of intestinal complications in fetuses with complex gastroschisis was 27.0%, with a higher prevalence of atresia (about 48%), followed by necrosis (about 25%). The prevalence of deaths in newborns with complex gastroschisis was 15.0%. The predictive ultrasound markers for complex gastroschisis were intraabdominal bowel dilatation (IABD) (RR 3.01, 95% CI 2.22 to 4.07; I2 = 15.7%), extra-abdominal bowel dilatation (EABD) (RR 1.55, 95% CI 1.01 to 2.39; I2 = 77.1%), and polyhydramnios (RR 3.81, 95% CI 2.09 to 6.95; I2 = 0.0%). This review identified that IABD, EABD, and polyhydramnios were considered predictive ultrasound markers for complex gastroschisis. However, evidence regarding gestational age at the time of diagnosis is needed.

Serum Interleukin (IL)-23 and IL-17 Profile in Inflammatory Bowel Disease (IBD) Patients Could Differentiate between Severe and Non-Severe Disease

Interleukin (IL)-17 and IL-23 are crucial for mediating gut mucosal inflammation in inflammatory bowel disease (IBD), which has led to new therapeutic strategies. We assessed the relevancy of IL-17 and IL-23 serum levels as potential biomarkers towards severe IBD discrimination and disease-related complications. Sixty-two patients diagnosed with Crohn’s disease (CD) and ulcerative colitis (UC) were included. Serum IL-17 and IL-23 were measured by sandwich enzyme-linked immunosorbent assays (ELISA). IL-23 and fecal calprotectin (FCal) were significantly higher in severe CD (p < 0.001) and UC (p < 0.001 and p = 0.001, respectively), compared to mild or moderate. Elevated C-reactive protein (CRP) was correlated with severe disease only in CD (p = 0.008), whereas for UC, disease severity was associated with increased IL-17 values (p < 0.001). Diagnostic role of IL-23 was superior to FCal in discriminating between severe and mild to moderate CD (p < 0.001). IL-23 levels were also significantly higher in CD patients with intestinal complications (p = 0.04). Both IL-17 and IL-23 correlate with IBD severity, and IL-23 might be a promising novel biomarker for severe CD. Identifying the dominant IL pathway involved in IBD severity could serve as guidance for clinical decision-making on biologic therapy.

LAPROSCOPIC COMMON BILE DUCT EXPLORATION: STENT DRAINAGE VERSUS T- TUBE DRAINAGE

Introduction: One of the safe &amp; feasible methods for the management of extra-hepatic bile duct calculi is laparoscopic bile duct exploration. Around 10-15% of the subjects who have surgery due to gallstone disease have choledocholithiasis associated with it. A standard procedure to prevent bile escape from the choledochotomy site is conventionally postoperative T-tube drainage following common bile duct exploration. &#x0D; Aims &amp; Objectives: Comparative study of laproscopic common bile duct exploration using stent drainage versus t- tube drainage.&#x0D; Material &amp; Methods: The study involved a total of 46 subjects with choledocholithiasis, who were categoryed in 2 categorys. Category I as a drainage category of stents and Category 2 as a drainage category of T-tubes. The subjects in both classes underwent LCBDE surgery. Of the 46 subjects operated, 23 were in category I (stent drainage category) and 23 were in category 2 (T-tube drainage category). &#x0D; Results: 23 subjects were categoryed in the stent drainage and T-tube drainage categories, respectively. In both classes, no perioperative or postoperative mortality was reported. Subjects had hypertension in stent drainage category 4 (17.39 percent) and 5 (21.73 percent) suffered from diabetes as a comorbid disease, while 2 (8.69 percent) subjects had jaundice. Four (17.39 percent) subjects with diabetes and three (13.04 percent) subjects with jaundice were found in T-tube drainage category 3 (13.04 percent) with hypertension. In both classes, no statistically significant difference was found. In terms of organisational results and outcomes, statistically significant variations were found in both categorys (Table 3). Mean operating time was 103± 22.4 in category I while 127±32.7 (P value &lt; 0.005) in category II. In the Stent Drainage Category, blood loss during procedure was 22±3.7 ml, while in the T-tube drainage category it was 38±5.1 (P value &lt; 0.005).&#x0D; Conclusion. After laparoscopic choledochotomy, primary closure of the bile duct with spontaneously reversible biliary stent placement is a viable and practicable process. With spontaneously removable biliary stents, less surgery time, less bleeding and less intestinal complications have been observed.&#x0D; Keywords: stent drainage, T- tube drainage, choledochotomy

Ultrasound Elastography in the Assessment of the Intestinal Changes in Inflammatory Bowel Disease-Systematic Review.

Inflammatory bowel disease (IBD) is a chronic condition affecting primarily the gastrointestinal tract and characterized by growing incidence worldwide. Complex diagnostic process of IBD as well as evaluation of disease activity and intestinal complications that are crucial for the therapeutic decisions, require repetitive, invasive, expensive, time-consuming and poorly tolerated tests. In contrast to endoscopy and computed tomography, ultrasound elastography (UE) is non-invasive, non-radiating and non-contrasting dependent tool which might be utilized in IBD patients for the assessment of the intestinal changes. Therefore, we performed the systematic review to evaluate the possible application of the ultrasound elastography for assessment of the intestinal changes in IBD. After the search of three databases: PubMed, World of Knowledge and Scopus, we identified 12 papers which were included in the final analysis. The majority of the studies were focused on the evaluation of the symptomatic ileal/ileocolonic strictures in Crohn’s disease patients that required surgical resection. Only one study concerned ulcerative colitis. The authors evaluated different UE techniques: strain elastography (SE), acoustic radiation force impulse (ARFI) and shear wave elastography (SWE). Results were expressed with semi-quantitative color mapping and strain measurement. Histological scores of inflammation and fibrosis in Crohn’s disease were used as a reference test in the majority of studies. Ultrasound elastography seems to be a promising novel imaging technique supporting evaluation of the intestinal strictures in Crohn’s disease patients in respect to fibrosis detection as well as differentiation between fibrosis and inflammation. However, further research is needed to establish the position of ultrasound elastography in IBD management.

Elaboration and Validation of Flowchart for the Prevention and Treatment of Intestinal Peristomal Skin Complications

Abstract Objective To build and validate a flowchart for the prevention and treatment of intestinal peristomal skin complications. Method For the construction of the algorithms, a systematic review was carried out in health sciences databases comprising the last 10 years. The evaluation of the algorithms was carried out by 38 nurses. For the validation of the algorithms, the Delphi technique was used. The statistical analysis used was the content validity index and the Cronbach alpha coefficient. The questionnaire was sent by e-mail and in person after approval by the Ethics and Research Committee. Results In the first evaluation of the algorithms, there was no agreement among the experts. However, after making the corrections suggested by the evaluators, the algorithms were resent, with a 100% consensus among the evaluators. The questions used to validate the algorithms contributed favourably to the internal consistency and content validation of the instrument, since the respective Cronbach alpha was 0.9062 and the global content validity index (g-CVI) was 0.91 in the first validation and 1.0 in the second validation. Conclusion After an integrative literature review, the flowcharts were built and validated by a professional with experience in the area, showing 100% agreement among the experts in the second evaluation.
