Modified Closed Reduction and Percutaneous Kirschner Wires Internal Fixation for Treatment of Supracondylar Humerus Fractures in Children.

Supracondylar humerus fractures are the most frequent fractures of the paediatric elbow. The present study introduced a modified surgical procedure for treatment of supracondylar humerus fractures in children. From February 2015 to August 2019, 73 patients with Gartland's type II and III supracondylar fractures were treated with this modified method. Totally, 68 of all patients were followed up for 3-12 months (mean 8.25 months). The evaluation results included fracture nonunion, ulnar nerve injury, pin track infection, carrying angle and elbow joint Flynn score. The results showed that bone union was observed in all children, one case had an iatrogenic ulnar nerve injury, and the symptoms were completely relieved in 4 months after removing of the medial-side pin. All children had no cubitus varus deformity and no pin track infection, and the rate of satisfactory results according to Flynn's criteria score was 100%. The modified closed reduction and Kirschner wires internal fixation could effectively reduce the rate of open reduction, the risk of iatrogenic ulnar nerve injury, and the incidence of cubitus varus deformity in treatment of supracondylar humerus fractures in children.

Surgical Treatment of Benign Retrorectal Masses in Adults: A Retrospective Study

Background: Tumors that occur in the retrorectal space are called retrorectal tumors. These tumors arise from various tissues. Late symptoms may therefore outweigh diagnosis and treatment. Therefore, the surgery becomes difficult.
 Aims and Objectives: Our study aims to reveal the difficulties in the diagnosis of retrorectal tumors, radiological diagnostic methods, and safe surgical excision surgical techniques.
 Materials and Methods: Twelve patients operated for retrorectal tömür between 2014 and 2020 were included in the retrospective study. Demographic features, clinical findings, diagnostic methods, surgical treatment procedures, evaluations of preoperative/postoperative complications, pathological classifications, length of hospital stay, and duration of surgery were studied.
 Results: Twelve patients [9 females, 3 males; the mean age was 39.3 ± 11.8 (22-56)] due to retrorectal tumors. All lesions were evaluated preoperatively using magnetic resonance imaging (MRI). According to the preoperative examination and radiological findings; Surgical resection was performed with an anterior approach to 3 patients, a posterior approach to 4 patients, and a combined approach to 5 patients. The mean tumor size was 8 ± 2.24 cm. Immature teratoma and epidermoid cyst (n = 6) were the most common tumors. We did not have any patients with features of malignancy on final histopathology.
 Conclusion: Although retrorectal tumors are difficult to diagnose, it is important to suspect clinically. A good evaluation of the patients with radiological imaging facilitates the resection of the tumor surgically. Surgery of the patient in centers specialized in these tumors increases surgical success.

Bipolar TURP decreases post-operative morbidity – A prospective study in a tertiary care hospital from north India

Background: Transurethral resection of prostate is considered as gold standard surgical procedure for treatment of benign enlargement of prostate. It can be performed in two forms- monopolar transurethral resection and bipolar transurethral resection.
 Aims and Objective: This study was conducted to know which energy source among monopolar and bipolar energy leads to more post-operative morbidity after performing transurethral resection of prostate.
 Materials and Methods: In this study, total eighty (80) cases were included. They were suffering from lower urinary tract symptoms which were diagnosed to be due to benign enlargement of prostate after careful clinical and radiological examination. In forty cases, transurethral resection of prostate was performed by using monopolar energy source and in another forty cases, resection of prostate by transurethral route was done using bipolar energy source.
 Results: In our study, we found that development of TURP syndrome was more in monopolar TURP group in which pre-operative weight of prostate was more than 50 grams in comparison to bipolar TURP group in which there was no incidence of development of TURP syndrome in same class. Further, post-operative hospital stay and post-operative urethral catheter in situ was less in bipolar TURP group in terms of days as compared to monopolar TURP group.
 Conclusion: Our study concludes that Bipolar TURP is better in terms of development of less post-operative morbidity as compared to monopolar TURP. Bipolar TURP must be used extensively in teaching hospitals where students take more time than a seasoned surgeon to perform a surgical procedure and bipolar TURP will come handy in that situation.

External and internal oblique abdominis muscle release (eimr) for complex incisional hernia repair: Modification of partition surgical technique

Incisional hernia is the name given to hernias that form in the incision site after abdominal operations. The only treatment option for incisional hernias is surgery and the repair of incisional hernias is still a serious issue for surgeons. The aim of this study is to present an alternative surgical treatment procedure for the treatment of incisional hernias. The study included patients who were diagnosed with complex incisional hernia and underwent surgery between November 2016 and December 2017. In addition to demographic data such as age and gender, the operative and postoperative morbidity and mortality rates were documented. The patients who underwent additional surgical procedure other than herniography were excluded from the study. The study included 16 patients who met the inclusion criteria. Of 16 patients, nine (56.25%) were male and seven (43.75%) were female. The mean age of the patients was 51.25 years and the mean body mass index was 25.3 kg/m2. The hernia size measured in the computed tomography was 11.01 cm on average in men and 11.56 cm on average in women. The intravesical pressure measured intraoperatively before the surgery was 3.4 mmHg on average. While the mean intravesical pressure was found as 12.25 mmHg after the abdomen was closed, the mean intravesical pressure was measured as 6.43 mmHg after the relaxation incision and graft installment. The duration of the surgery was 48 minutes on average. In the postoperative period, paralytic ileus responsive to treatment was observed in two patients and skin necrosis was observed in one patient. No pulmonary embolism, respiratory problems and compartment syndrome that may cause mortality developed in patients. No recurrence was observed in patients in the control one year after the surgery. The golden standard surgical method for the incisional hernia surgery has yet to be determined. There is still a need for prospective randomized studies. We believe that our technique can be an alternative to other techniques in the incisional hernia surgery due to its easy applicability and low rate of complications.

Reporting Templates for MRI and Water-Soluble Contrast Enema in Patients With Ileal Pouch-Anal Anastomosis: Experience From a Large Referral Center.

Ileal pouch-anal anastomosis (IPAA) surgery is the reference standard surgical procedure for treatment of ulcerative colitis and most patients with familial adenomatous polyposis. This procedure allows preservation of fecal continence and gastrointestinal continuity. However, it is associated with a wide variety of complications, which often have nonspecific and overlapping clinical presentations, making imaging an important part of workup for pouch dysfunction. The purpose of this article is to propose structured reporting templates for MRI and water-soluble contrast enema (WSCE), based on our referral pouch center's experience, in patients who have undergone IPAA surgery. We review salient surgical technique, pouch anatomy, and imaging protocols, with an emphasis on a systematic search pattern for evaluation of ileal pouch complications using proposed structured reporting templates for MRI and WSCE.

P656 Epidemiology and outcomes associated with local surgical and intersphincteric ligation procedures for complex cryptoglandular fistulas: A systematic literature review

Abstract Background Studies suggest that complex cryptoglandular fistulas (CCF) are difficult to treat, resulting in higher intervention failure rates and functional disability. This systematic literature review (SLR) assessed the epidemiology of cryptoglandular fistula and outcomes associated with local, surgical and intersphincteric ligation procedures for treatment of CCF. Methods PubMed and Embase were searched to identify articles published in the past 5 years (2015–2020) relating to incidence or prevalence of cryptoglandular fistula and outcomes of surgical interventions for CCF (PROSPERO registration number CRD42020177732). Outcomes of interest included fistula closure/healing, recurrence, surgery failure, post-operative pain and faecal incontinence. The interventions included anal flap procedures, fistulectomy, fistulotomy, primary sphincteroplasty, modified Park’s technique, LIFT or BIOLIFT, and TROPIS. Two trained reviewers used pre-specified eligibility criteria to identify studies for inclusion and evaluate risk of bias using the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool for observational studies. Data were extracted for a range of variables, including study type and design, population, outcomes and limitations. Results In total, 148 studies were identified that met a priori eligibility criteria for all cryptoglandular fistulas and all intervention types. Of these, two reported incidence or prevalence of cryptoglandular fistulas and 18 reported outcomes for the interventions of interest in CCF. Prevalence of cryptoglandular fistulas was reported as 1.35 per 10 000 patients without Crohn’s disease, and 52.6% of patients without IBD were found to progress from anorectal abscess to fistula over 12 months. Studies examining the clinical outcomes reported primary healing rates of 57.4–100.0%, recurrence rates of 4.9–61.0% and failure rates of 2.8–18.0% of patients. Only five studies reported post-operative pain as a clinical outcome. Overall, these studies suggest patients experience no or minimal longer-term post-operative pain. In studies reporting post-operative faecal incontinence following anal mucosal flap procedures, observed incontinence rates were low, as measured using Wexner or Miller scoring. None of the studies involving fistulectomy measured faecal incontinence. Conclusion This SLR provides a summary of outcomes from a selected group of surgical interventions for CCF. Healing rates vary according to surgery type; however, differences in study design and heterogenous definitions prevent direct comparison. Overall, the published literature indicates low to modest rates of CCF recurrence and limited data on faecal incontinence and longer-term post-operative pain.

Periprosthetic Fungal Infections in Severe Endoprosthetic Infections of the Hip and Knee Joint-A Retrospective Analysis of a Certified Arthroplasty Centre of Excellence.

The treatment of periprosthetic joint infections (PJI), and especially of re-infections, poses a highly complex problem in orthopaedic surgery. While fungal infections are rare, they present a special challenge. The therapy is often protracted and based on limited evidence. A total of 510 hip and knee revision surgeries were analysed for the occurrence of bacterial and fungal PJI. In patients with PJI, the duration of the hospital stay and the incidence of disarticulation of the infected joint were recorded. Out of the analysed revision arthroplasties, 43.5% were due to PJI. Monomicrobial infection occurred in 55.2%, dual microbial infection in 21.4%, and polymicrobial (≥3 different bacterial or fungal species) infection in 17.2% of the cases. Overall, Candida species were detected in 12.4% cases. Candida albicans was the main fungal pathogen. In 6.9% of cases, disarticulation of the joint was the only option to control PJI. The detection of polymicrobial infection more than doubled in follow-up revisions and there was a strong association between detection of Candida infection and disarticulation (OR 9.39). The majority of fungal infections were mixed infections of bacteria and Candida albicans. The choice of a biofilm penetrating antimycotic, e.g., caspofungin, together with a sufficient standard procedure for detection and surgical treatment can help to control the infection situation. Fungal infection often proves to be more difficult to treat than anticipated and is more frequent than expected.

Management of Recalcitrant Cubital Tunnel Syndrome.

Cubital tunnel syndrome is a common upper extremity compressive neuropathy. Recalcitrant cubital tunnel syndrome poses diagnostic and treatment challenges. Potential etiologies of persistent or recurrent symptoms after surgical treatment include an inaccurate preoperative diagnosis, incomplete nerve decompression, iatrogenic injury, postsurgical perineural adhesions, irreversible nerve pathology, or conditions associated with secondary nerve compression. Confirmation of recalcitrant ulnar nerve pathology relies on a thorough history to consider symptoms and chronology, careful examination to quantify nerve function and to assess for focal nerve provocation, and objective testing to highlight a possible nerve lesion such as ultrasonography and electrodiagnostic testing. Conservative treatment may provide symptomatic relief; however, surgical management such as revision neuroplasty, neurolysis, nerve reconstruction, and/or anterior transposition may be indicated. Optimizing the biology of the local nerve environment is critical. No surgical treatment procedure has shown superiority over another; however, individualized treatment is emphasized to improve symptoms and maximize nerve recovery potential.

Endoscopically Assisted Marginal Mandibulectomy Using an Intraoral Approach Alone for Squamous Cell Carcinoma of the Posterior Mandibular Gingiva: A Technical Note.

Technical note. Marginal mandibulectomy is a surgical procedure for treatment of mandibular gingival tumors. The intraoral approach to the posterior region of the mandible for marginal mandibulectomy is difficult due to limited access and operating field visibility; the conventional surgical procedure may require some skin incisions. This report discusses the effectiveness of endoscopic assistance in marginal mandibulectomy. This article describes endoscopically assisted marginal mandibulectomy using an intraoral approach alone for squamous cell carcinoma of the posterior mandibular gingiva. The advantages of this surgical method are twofold: (1) superior visibility to the lower edge of the mandible without any skin incision; and (2) safe surgical confirmation of important anatomy on the buccolingual side (e.g., mental foramen, lingual nerve, mandibular foramen, and neurovascular bundle). This minimally invasive approach without any skin incision, as well as the superior visibility of the operating field, are important advantages of endoscopically assisted marginal mandibulectomy that cannot be obtained by other surgical methods. Endoscopically assisted marginal mandibulectomy using an intraoral approach alone may be useful because it avoids damage to facial skin and improves safety by employing an enlarged bright field.

Health-related quality of life after curative resection for gastric adenocarcinoma.

BACKGROUNDWith improved survival in gastric cancer patients, health-related quality of life has become an important clinical endpoint alongside primary oncological outcomes.AIMTo investigate health-related quality of life after various surgical procedures for gastric cancer treatment.METHODSThe validated Slovenian version of the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (QLQ-C30) and its gastric cancer-specific module (QLQ STO-22) was sent for self-completion to patients that underwent curative resection for gastric adenocarcinoma between January 2014 and December 2018 at our centre. In total, 116 patients responded. Scores were compared between patients after subtotal distal vs total gastrectomy and patients after subtotal distal gastrectomy with Billroth II vs Roux-en-Y reconstruction.RESULTSInterestingly, the extent of resection did not influence daily functioning; however, more dysphagia and eating restrictions were reported in patients after total gastrectomy when compared to patients after subtotal distal gastrectomy. Moreover, patients with Billroth II reconstruction after subtotal distal resection experienced worse physical and role functioning and reported more pain, fatigue and reflux compared to Roux-en-Y reconstruction.CONCLUSIONBased on our results, Roux-en-Y reconstruction after subtotal distal gastrectomy should be preferred over Billroth II reconstruction. The data obtained from this study will help surgeons when preoperatively informing their patients about expected functional outcomes after gastrectomy and enable them to ensure proper supportive care of their patients in the postoperative period.

Stigmatic Impact of COVID-19 Pandemic on Head & Neck Cancers Survivors.

Social stigma is the spoilation of the social image of an individual, which leads to the social disapproval of the individual by the community. Patients of many diseases like HIV, deafness, and reproductive disorders often face social disproval. Head & neck cancer survivors perceived stigma due to the mutilation that occurred after surgical treatment procedures. The novel coronavirus is a recently emerged zoonotic viral agent that affects the respiratory system of humans. Following its outbreak from the Wuhan city of China, the COVID-19 spreaded fiercely around the globe, forming a pandemic. Since COVID-19 is a contagious disease with no available treatment, social distancing is considered as the best strategy to prevent the geometric spread of infection. With the social distancing model, the head & neck cancer survivors along with the various other stakeholders perceived stigma being a high-risk group for COVID-19 infection. As the pool of caregivers is diminished due to pandemic, head & neck cancer survivors face increased social isolation and perceived stigma in asking for help from relatives. At the time of the pandemic, social support is critical to fighting against the disease. Social distancing should be maintained along with communication with the patients through calls, text, and online social platforms. It is not wise to stigmatize disease as, in that case, patients who are infected with the disease will try to hide it and avoid seeking medical care. With the promotion of social distancing, it is crucial to convey awareness regarding not to stigmatize the disease.

Comparative study between great saphenous vein endovenous laser ablation and modified hemodynamic correction (conservative hemodynamic correction of venous insufficiency) as a treatment for varicose veins

Background Varicose veins could be a complicated condition, which may lead to limb swelling, pain, and venous ulcer. Conservative hemodynamic correction of venous insufficiency (CHIVA) has been developed through the past two decades and is currently the second most common surgical procedure for the operative treatment of varicose veins. Endovenous laser treatment of great saphenous vein was approved by FDA in 2002 and short saphenous vein (SSV) was approved in 2003. Endovenous laser ablation (EVLA) is a clinically safe, feasible, and well-tolerated technique without scar and allows people to return to their normal daily activities rapidly. Patients and methods In a prospective comparative study between January 2018 and January 2020, 40 patients complaining of varicose veins were assessed according to the Clinical-Etiological-Anatomical-Pathophysiological (CEAP) classification and ultrasonic duplex and arranged into group I (CHIVA) and group II (EVLA). Both CHIVA operation and EVLA were performed under local anesthesia. Follow-up for 6 months was done. Results Recurrence occurred in 2/20 and 0/20 patients in CHIVA and EVLA groups, respectively. Regarding the aesthetic satisfaction of the patient, EVLA was better, with two unsatisfied patients in EVLA in contrast to five unsatisfied patients in CHIVA. The wound infection rate was 1/20 and 0/20 in CHIVA and EVLA, respectively. CHIVA is favored over EVLA considering the rest of the complications. Bruises, thrombosis, and nerve damage are found to be 5/20, 0/20, and 0/20, respectively, in CHIVA group when compared with the results of EVLA group, which were 9/20, 1/20, and 2/20, respectively. Conclusion CHIVA is safe, effective, and less invasive. EVLA is now considered as one of the top technologies to be used in the management of varicose veins with good functional outcome. EVLA can be done as an outpatient procedure. Each type of these interventions should be tailored according to each patient’s variables such as degree of reflux in great saphenous vein, presence of incompetent perforators, and aesthetic requirements of the patient.

Factors affecting functional outcome after anterior cervical discectomy and fusion

Background:Although anterior cervical discectomy and fusion (ACDF) represents a standardized procedure for surgical treatment of a cervical herniated disc, several variables could affect patients' clinical and radiological outcome. We evaluated the impact of sex, age, body mass index (BMI), myelopathy, one- or two-level ACDF, and the use of postoperative collars on functional and radiological outcomes in a large series of patients operated for ACDF.Materials and Methods:Databases of three institutions were searched, resulting in the enrollment of 234 patients submitted to one- or two-level ACDF from January 2013 to December 2017 and followed as outpatients at 6- and 12-month follow-up. The impact of variables on functional and radiological outcomes was evaluated using univariate and multivariate logistic regression analysis.Results:At univariate analysis, female sex, higher BMI, two-level ACDF, and postoperative collar correlated with a significantly worse early and late Neck Disability Index (NDI). Multivariate analysis showed that male patients had a lower risk of worse early (P = 0.01) and late NDIs (P = 0.009). Patients with myelopathy showed better early NDI (P = 0.004). Cervical collar negatively influenced both early and late NDIs (P < 0.0001), with a higher risk of early nonfusion (P = 0.001) but a lower risk of late nonfusion (P = 0.01). Patients operated for two-level ACDF have a worse early NDI (P = 0.005), a worse late NDI (P = 0.01), and a higher risk of early nonfusion (P = 0.048). BMI and age did not influence outcome.Conclusions:Female sex, two-level surgery, and the use of postoperative collars significantly correlate with worse functional outcomes after one- or two-level ACDF.

German Registry for Cardiac Operations and Interventions in Patients with Congenital Heart Disease: Report 2020-Comprehensive Data from 6 Years of Experience.

Background Based on a quality assurance initiative of the German Society for Thoracic and Cardiovascular Surgery (DGTHG) and the German Society for Pediatric Cardiology and Congenital Heart Defects (DGPK), a voluntary registry was founded for assessment of treatment and outcomes of patients with congenital heart disease in Germany. This evaluation by the German Registry for cardiac operations and interventions in patients with congenital heart disease reports the data and the outcome over a 6-year period in patients undergoing invasive treatment. Methods This real-world database collects clinical characteristics, in-hospital complications, and medium-term outcome of patients who underwent cardiac surgical and interventional procedures within the prospective, all-comers registry. Patients were followed-up for up to 90 days. Results In the period from 2013 to 2018, a total of 35,730 patients, 39,875 cases, respectively 46,700 procedures were included at up to 31 German institutions. The cases could be subcategorized according to the treatment intention into 21,027 (52.7%) isolated operations, 17,259 (43.3%) isolated interventions, and 1,589 (4.0%) with multiple procedures. Of these, 4,708 (11.8%) were performed in neonates, 10,047 (25.2%) in infants, 19,351 (48.5%) in children of 1 to 18 years, and 5,769 (14.5%) in adults. Also, 15,845 (33.9%) cases could be allocated to so-called index procedures which underwent a more detailed evaluation to enable meaningful comparability. The mean unadjusted in-hospital mortality of all cases in our registry ranged from 0.3% in patients with isolated interventions and 2.0% in patients with surgical procedures up to 9.1% in patients undergoing multiple procedures. Conclusion This annually updated registry of both scientific societies represents voluntary public reporting by accumulating actual information for surgical and interventional procedures in patients with congenital heart disease (CHD) in Germany. It describes advancements in cardiac medicine and is a basis for internal and external quality assurance for all participating institutions. In addition, the registry demonstrates that in Germany, both interventional and surgical procedures for treatment of CHD are offered with high medical quality.

Surgical Procedure in the Treatment of Organized Chronic Subdural Hematoma: A Single-Center Experience.

Organized chronic subdural hematoma (CSDH) is a special type of CSDH. However, the optimal surgical procedure has not been established. We present our experience here to discuss the surgical procedure in treatment of organized CSDH. Thirty-three patients with organized CSDH were admitted between January 1, 2008 and January 1, 2018. Age, gender, clinical symptoms, imaging data, type of surgical procedure, Barthel index (BI), and postoperative complications were collected and retrospectively analyzed. The BI was assessed both pre and postoperatively (1 week and 1 month after surgery). Overall, 14 patients underwent large craniotomy and 19 patients underwent small craniotomy. No significant differences in gender, age, initial clinical symptoms, and preoperative BI were found between the groups (p > 0.05). Among the 14 patients who underwent large craniotomy, 2 patients developed epilepsy after the operation, while 1 patient had postoperative aphasia. None of the patients had recurrence in 6 months postoperatively. Among the 19 patients who underwent small craniotomy, 1 patient developed an acute subdural hematoma and 1 patient developed aphasia. No obvious complications were found in the remaining 18 patients and none of the 19 patients had recurrence in 6 months postoperatively. BI scores of the small craniotomy group were significantly better than those of the large craniotomy group at 1 week postoperatively (p < 0.05). However, there was no significant difference in the 1-month results (p > 0.05). According to our single-center experience, a small craniotomy for treating organized CSDH can be considered as an alternative to a larger craniotomy.

Sciatic vessels – a case report

Description of the case. We present the case of a 75-year-old patient with symptoms of acute right lower limb ischemia. The patient was discharged home in good condition, and remains in outpatient control to this day. Conclusion. The popliteal artery proved to be available, but much deeper than usual.

Transforaminal lumbar interbody fusion in degenerative spondylolisthesis

Introduction Spinal fusion surgery is a common technique used to treat degenerative lumbar pathologies including disc herniation with instability, spinal stenosis, and degenerative spondylolisthesis (DS). Minimally invasive transforaminal lumbar interbody fusion (TLIF) is a common surgical procedure for treatment of DS. Aim We aimed to assess the outcomes of TLIF in DS. Patients and methods This study was conducted on 15 patients treated for DS treated with TLIF. A written informed consent was taken from all participants after proper explanation of the study. The study assessed perioperative results related to the operative procedure such as blood loss, operation time, hospital stay, and complications. Oswestry Disability Index (ODI) questionnaire was filled for functional evaluation, and the visual analog scale was used to assess pain preoperatively and postoperatively. Result A total of 15 cases were included. The mean age of the included cases was 53.67 years, the mean BMI was 26.73, 53.3% of cases were female, and 33.3% of patients were smokers. There was a significant decrease in visual analog scale ODI after operation. Regarding complications, 73.3% had no early complications but 13.3% had wound infection and 6.7% had positioning neuropathy and postoperative hematoma. Late complications were founded in 33.3% in the form of adjacent segment disease in 13.3%, arthrodesis in 13.3%, and fusion failure in 6.7%. Conclusion This study shows that TLIF is an effective procedure in surgical management of DS. The TLIF gives better results regarding reduction of low back pain and leg pain, as well as reduction in ODI score in early follow-ups and similar results in late follow-ups.

Surgical Correction of Hirschsprung's Disease in Children Using the Soave-Boley Technique with Manual Colorectal Anastomosis

Introduction. Current trends in surgical treatment of Hirschsprung's disease are aimed at minimally invasive interventions. However, the experience of using Soave-Boley procedure in surgical treatment of Hirschsprung's disease in children of different ages is valuable in the arsenal of differentiated approach to the treatment of this pathology.&#x0D; The objective of the research was to evaluate the results of surgical correction of Hirschsprung's disease in children using the Soave-Boley technique with manual colorectal anastomosis.&#x0D; Materials and Methods. The analysis of surgical treatment of 1,187 children with different forms of Hirschsprung’s disease aged from birth to 18 years over the period 1980-2020 was conducted in the National Children's Specialized Hospital“ Okhmatdyt”. Surgical correction of Hirschsprung's disease using the Soave-Boley technique was performed in 597 children. Before surgery, 156 patients underwent the first stage of treatment that consisted in the creation of a protective colostomy; in 441 cases, this intervention was performed without an intestinal stoma; the benefits of the Soave-Boley technique were evaluated.&#x0D; Results. All the patients survived. In 15 (2.51%) out of 597 children, in the early postoperative period, there were observed: retrocolic hematoma (n = 2), retrocolic abscess (n = 7), anastomotic leak (n = 2), adhesive intestinal obstruction (n = 3), intussusception (n = 1). Fourteen (2.36%) patients developed surgical complications in the long-term period: residual aganglionosis (n = 9), anastomotic stenosis (n = 4) and coloptosis. Repeated Soave-Boley operation with manual colorectal anastomosis was successfully performed in 26 (4.362%) patients after primary correction of Hirschsprung's disease using different methods. Periodic episodes of fecal smearing in the remote period in 45 (7.53%) children were eliminated by conservative treatment. The success of this technique is confirmed by a much lower number of early (2.51%) and late (2.36%) postoperative surgical complications, as compared to those after using other methods of open surgical correction - 17.52% and 16.35%, respectively.&#x0D; Conclusions. Surgical correction of Hirschsprung's disease in children using the Soave-Boley technique with manual colorectal anastomosis allows better control over applying each suture, anatomical joining the edges of the bowel, and reducing trauma to the rectal mucosa, which ensures the high reliability of colorectal anastomosis; it is the most effective way of radical correcting Hirschsprung' s disease in children in an open way in one-stage or two-stage interventions, and this technique is the operation of choice for secondary surgical correction of Hirschsprung's disease.

Transanal vs laparoscopic total mesorectal excision for rectal cancer: a multicenter randomized phase III clinical trial (TaLaR trial) protocol.

BackgroundTotal mesorectum excision (TME) is considered the standard surgical procedure for rectal-cancer treatment. Transanal TME (taTME) is a new procedure to treat low rectal cancer. Some published studies have proven that taTME can provide a better-quality resected specimen in low-rectal-cancer patients in comparison to the transabdominal procedure, yet long-term outcomes must be investigated. We designed this non-inferiority trial (TaLaR trial) to compare short-term and long-term outcomes between taTME and laparoscopic TME (lapTME) for rectal cancer.MethodsThe TaLaR trial is a phase III open-labeled multicenter randomized–controlled trial. Patients who are diagnosed with rectal cancer with no more than T3N2 stage, and with the tumor location below the peritoneal reflection by magnetic resonance imaging scan, digital rectal examination, or colonoscopy, qualify for this study. After calculating, a total of 1,114 patients (557 per group) will be randomly allocated to either the taTME or the lapTME group. Primary endpoints are the 3-year disease-free survival (DFS) rate and the 5-year overall survival (OS) rate. Secondary endpoints include specimen quality, perioperative results, pelvic and anal function, and quality of life.DiscussionThe TaLaR trial is expected to clarify whether taTME can achieve comparable oncological outcomes, as well as improve specimen quality and recovery conditions in rectal-cancer patients compared with lapTME.

Bifunctional, Copper-Doped, Mesoporous Silica Nanosphere-Modified, Bioceramic Scaffolds for Bone Tumor Therapy

In the traditional surgical intervention procedure, residual tumor cells may potentially cause tumor recurrence. In addition, large bone defects caused by surgery are difficult to self-repair. Thus, it is necessary to design a bioactive scaffold that can not only kill residual tumor cells but also promote bone defect regeneration simultaneously. Here, we successfully developed Cu-containing mesoporous silica nanosphere-modified β-tricalcium phosphate (Cu-MSN-TCP) scaffolds, with uniform and dense nanolayers with spherical morphology via 3D printing and spin coating. The scaffolds exhibited coating time- and laser power density-dependent photothermal performance, which favored the effective killing of tumor cells under near-infrared laser irradiation. Furthermore, the prepared scaffolds favored the proliferation and attachment of rabbit bone marrow-derived mesenchymal stem cells and stimulated the gene expression of osteogenic markers. Overall, Cu-MSN-TCP scaffolds can be considered for complete eradication of residual bone tumor cells and simultaneous healing of large bone defects, which may provide a novel and effective strategy for bone tumor therapy. In the future, such Cu-MSN-TCP scaffolds may function as carriers of anti-cancer drugs or immune checkpoint inhibitors in chemo-/photothermal or immune-/photothermal therapy of bone tumors, favoring for effective treatment.
