Laparoscopic Versus Conventional Open Congenital Duodenal Obstruction Repair: A Systematic Review and Meta-analysis.

BACKGROUND: We conducted a systematic review and meta-analysis to evaluate the safety and effectiveness of laparoscopic surgery (LS) compared to open surgery (OS) for congenital duodenal obstruction (CDO). METHODS: We conducted a literature review to find studies comparing LS and OS in neonates with CDO. A meta-analysis was conducted to systematically compile and compare factors, including surgical duration, time of feeding initiation, hospital length of stay (LOS), and postoperative complications. RESULTS: Eleven studies with 1615 patients (LS: 338, OS: 1277) met inclusion criteria. Operative time was observed to be much shorter in the OS group (I2 = 97%); weighted mean difference (WMD) 60.29; 95% confidence interval (CI): 30.29 to 90.28; p < 0.0001). The LS group had a significantly shorter time to initiate feeding (I2 = 0%; WMD -3.38, 95% CI: -4.35 to -2.41; p < 0.00001), shorter time to full feeding (I2 = 0%; WMD -3.64, 95% CI: -5.06 to -2.22; p < 0.00001), and shorter LOS (I2 = 52%; WMD -3.42, 95% CI: -5.75 to -1.08; p = 0.004). There were no significantly differences in the rates of anastomotic leak (I2 = 24%; OR 0.76, 95% CI: 0.12 to 4.67; p = 0.76), anastomotic stricture (I2 = 0%; OR 1.12, 95% CI: 0.39 to 3.20; p = 0.83), postoperative ileus (I2 = 0%; OR 0.60, 95% CI: 0.21 to 1.74; p = 0.34), and overall complications between the groups (I2 = 59%; OR 0.86, 95% CI: 0.42 to 1.74; p = 0.68). The LS group, however, had a significantly decreased frequency of wound infection (I2 = 0%; OR 0.26, 95% CI: 0.08 to 0.82; p = 0.02). CONCLUSION: Despite certain limitations in our analysis, the laparoscopic approach was associated with comparable postoperative outcomes. LEVELS OF EVIDENCE: 2a. TYPE OF THE STUDY: Meta analysis.

Shehata technique versus Fowler-Stephens orchidopexy in intra-abdominal testis: A meta-analysis.

INTRODUCTION: The management of intra-abdominal testis (IAT) represents a significant clinical challenge, necessitating the transposition of the testis from the abdominal cavity to the scrotum. This procedure is rendered complex by the abbreviated length of the testicular vessels. OBJECTIVE: Our purpose in this study was to conduct a systematic review and meta-analysis comparing Shehata technique (ST) versus Fowler Stephens technique (FST) in treating patients with IAT. STUDY DESIGN: We conducted a comprehensive literature search using several databases, including Ovid Medline, Cochrane, PubMed, Google Scholar, Web of Sciences, EMBASE, and SCOPUS until February 2024. This study included research that compared ST and FST for managing intra-abdominal testis. We evaluated the rates of atrophy and retraction, as well as the overall success rates, for both techniques. RESULTS: Six studies were identified as appropriate for meta-analysis, comparing orchidopexy performed using the ST with 169 patients, against the FST involving 162 patients. The comparison showed no statistically significant age difference at the time of surgery between the groups (I2 = 0%) (WMD 0.05, 95% CI - 1.24 to 1.34; p = 0.94). Operative time in first the stage was lower in the FST group than ST group (I2 = 95%) (WMD 10.90, 95% CI 1.94 to 19.87; p = 0.02). Operative time in the second stage was lower in the ST group than FST group (I2 = 83%) (WMD - 6.15, 95% CI - 12.21 to -0.10; p = 0.05). Our analysis showed that ST had a similar atrophy rate (I2 = 0%) (OR: 0.45, 95% CI: 0.20 to 1.01; p = 0.05). No difference was found between techniques in terms of retraction rate (I2 = 0%) (OR: 0.64, 95% CI: 0.17 to 2.47; p = 0.52). The ST demonstrated a notably higher overall success rate compared to FST (I2 = 1%) (RR: 1.14, 95% CI: 1.03 to 1.27; p = 0.009). Overall success rate in ST and FST were 87% and 74%, respectively. Overall atrophy rate in ST and FST were 5% and 12%, respectively. Overall retraction rate in ST and FST were 5% and 10%, respectively. DISCUSSION: The ST, renowned for its pioneering two-stage laparoscopic approach that leverages mechanical traction to lengthen the testicular vessels, is gaining popularity due to its recognized safety and efficacy. Conversely, the Fowler-Stephens technique, a traditional method that relies on collateral blood supply for testicular mobilization, has come under examination for its potential link to an increased risk of testicular atrophy. CONCLUSION: This meta-analysis reveals that the Shehata technique has similar or better outcomes compared to the Fowler-Stephens technique in IAT management. Further prospective multicentric randomized controlled trials are warranted.

Respiratory symptoms and pulmonary function impairment among textile industry workers in Alexandria, Egypt.

Occupational exposure to cotton dust is still an important cause of respiratory problems in textile workers particularly in less developed countries like Egypt. Evaluate respiratory symptoms and diseases, and pulmonary function pattern among Egyptian textile workers. Cross sectional comparative study was conducted from December 2019 to September 2020 in a textile factory in Egypt; 364 male workers (184 cotton dust exposed workers, and 180 unexposed workers) were included. Participants were subjected to an interviewing questionnaire, British Medical Research Council questionnaire, anthropometric measurements, pulmonary function tests, and byssinosis grading format. Descriptive and analytic statistics were conducted. Chronic cough, phlegm production, and shortness of breath grade I, II and III were more reported in cotton dust exposed workers than unexposed workers (P#x003C;0.01, P#x003C;0.01, and P=0.02, respectively). Prevalence of chronic bronchitis was significantly higher among cotton dust exposed workers (12%) than unexposed workers (3.9%) (P#x003C;0.01). The mean percent predicted values of lung function indices reflecting large-1irway function (VC, FVC, FEV1, FEV1%, PEFR, and FEF75) were significantly lower in cotton dust exposed workers (P#x003C;0.01). Prevalence of byssinosis was 22.8%. Workers with byssinosis had significantly higher prevalence of respiratory symptoms, chronic bronchitis, cross-shift reduction in PEFR and significant decrease in mean percent predicted values of FVC, FEV1, PEFR, FEF75, and FEF50 than workers without byssinosis. This study revealed a substantial association between cotton dust exposure at work and respiratory symptoms and morbidity. Regular measurement of cross shift change in PEFR is recommended among exposed workers for early diagnosis of byssinosis.

Management strategy and outcomes of sacrococcygeal teratoma - an Egyptian multicenter experience.

OBJECTIVES: Nationwide criteria regarding patients with sacrococcygeal teratoma (SCT) are still lacking in Egypt. We aimed to present a multicenter study regarding the management and outcomes of this tumor to evaluate our national treatment strategy. METHODS: A retrospective analysis including all patients with SCT who were managed at four major Egyptian centers between 2013 and 2023. Clinical data, surgical approaches, and short- and long-term outcomes were discussed. RESULTS: The study included 95 patients (74 were females). Antenatal diagnosis was reported in 25% of patients. Seventy-one patients (74.7%) were classified as Altman type I/II. Surgery was performed via a perineal approach in 75 patients, whereas the remaining 20 underwent a combined abdominoperineal approach. Vertical elliptical incision with midline closure was conducted in 51.5% of patients, followed by classic or modified chevron incisions. Benign mature teratoma was detected in 82% of patients. At a median follow-up of 57 months, eight patients (8.5%) had relapsed. The 5-year overall survival (OS) and event-free survival (EFS) of all patients were 94% and 91%, respectively. In the after-care monitoring, 19 patients (20%) had urinary or bowel dysfunctions. Nine of them were managed using medications. Clean intermittent catheterization was practiced in another five patients. The remaining five underwent further surgical interventions. CONCLUSION: Favorable outcomes were achieved in our country during the last decade. Diverse perineal incisions were performed for resection, and vertical elliptical with midline closure was the commonest. During follow-up, 20% of patients developed urological or bowel dysfunctions that required medical and surgical treatment modalities to improve their quality of life.

Transanal recto-anal anastomosis for treatment of rectal atresia: a review of 4 cases.

INTRODUCTION: Rectal atresia is a rare subtype of anorectal malformations in which the patients are born with a normal anal canal but have complete atresia located few centimeters proximal to the dentate line. We present the transanal end-to-end rectoanal anastomosis as a surgical technique for the management of these patients, highlight the outcomes, and emphasize on some clinical tips. METHODS: Four patients were diagnosed as having rectal atresia on clinical and radiological basis. All of them underwent single loop low sigmoid colostomy in the first 24 h. After 6 months, transanal end-to-end rectoanal anastomosis was performed followed by closure of the stoma 3 months later. RESULTS: The 2 cases that are older than 3 years demonstrated normal continence and are clean between bowel movements, while the other two showed good anal tone and passing stools between 1-3 times daily, being dry in between. CONCLUSION: Transanal recto-anal anastomosis allows a safer route of anatomical reconstruction of the anorectum, therefore avoiding the potential complications associated with the other more invasive approaches.

Congenital aflatoxicosis, mal-detoxification genomics & ontogeny trigger immune-mediated Kotb disease biliary atresia variant: SANRA compliant review.

Biliary atresia (BA) is the most common indication for pediatric liver transplantation. We describe The BA variant: Kotb disease. Liver tissue in the Kotb disease BA is massively damaged by congenital aflatoxicosis resulting in inflammation, adhesions, fibrosis, bile duct proliferation, scarring, cholestasis, focal syncytial giant cell transformation, and typical immune response involving infiltration by CD4+, CD8+, CD68+, CD14+, neutrophil infiltration, neutrophil elastase spill, heavy loads of aflatoxin B1, accelerated cirrhosis, disruption of p53 and GSTPi, and have null glutathione S transferase M1 (GSTM1). All their mothers are heterozygous for GSTM1. This inability to detoxify aflatoxicosis results in progressive inflammatory adhesions and obliterative cholangiopathy early in life. The typical disruption of both p53 and GSTPi causes loss of fidelity of hepatic regeneration. Hence, regeneration in Kotb disease BA typically promotes accelerated cirrhosis. The immune response in Kotb disease BA is for damage control and initiation of regeneration, yet, this friendly fire incurs massive structural collateral damage. The Kotb disease BA is about actual ongoing hepatic entrapment of aflatoxins with lack of ability of safe disposal due to child detoxification-genomics disarray. The Kotb disease BA is a product of the interaction of persistent congenital aflatoxicosis, genetic lack of GSTM1 detoxification, ontogenically impaired activity of other hepatic detoxification, massive neutrophil-elastase, immune-induced damage, and disturbed regeneration. Ante-natal and neonatal screening for aflatoxicosis, avoiding cord milking, and stringent control of aflatoxicosis content of human, poultry and live-stock feeds might prove effective for prevention, prompt diagnosis and management based on our recent understanding of its patho-genomics.

Are online discussion forums useful platforms for paediatric surgeons to seek advice regarding patient management? A review of the queries posted on the world federation of association of pediatric surgeons facebook group (The Pediatric Surgeon's Lounge).

Background: Social media platforms are popular places for discussing difficult cases amongst the surgeons. Paediatric Surgeon's Lounge (PSL) is a closed Facebook group for the interaction of paediatric surgeons from different parts of the world. We aim to assess the safety and utility of the responses given by the members of the PSL group to the queries about the management of paediatric surgical cases. Methods: All posts on PSL between January and July 2021 were retrospectively screened to select the patient management-related queries. For each included query, all the responses were scrutinised for their utility and safety. The utility was categorised as helpful or not helpful, and the safety of these responses was categorised as safe or unsafe. A note was also made whether any unsafe response was rectified in the subsequent responses or not. The proportion of each response category was calculated. Results: Twenty-two queries with a total of 353 responses were assessed. The median (range) number of responses per query was 10 (2-45). The proportion of helpful, safe and rectified unsafe responses was 91.5% (307/353), 96.8% (342/353) and 36% (4/11), respectively. Conclusions: PSL is a safe and helpful platform for taking advice regarding the management of paediatric surgical cases.

The Management of Intraabdominal Testis: A Survey of the World Federation of Associations of Pediatric Surgeons (WOFAPS) Practices.

Background and Objective: The optimal treatment protocol of intraabdominal testis is still a matter of debate and until now there are a lot of areas of controversy as regards this challenging subtype. The aim of this report is to document current practice patterns among surgeons from different continents through an online Redcap survey supervised the World Federation of the Association of Pediatric Surgeons (WOFAPS). Methods: A 16-question-survey related to the management of intraabdominal testis was created and administered via RedCap. The WOFAPS headquarters sent an email to all members inviting voluntary survey participation. Data were entered using Microsoft EXCEL spreadsheet and analyzed. Descriptive statistics were performed for each survey item. Results: There were 436 WOFAPS members who participated in this study with a response rate of 29%, and the vast majority were pediatric surgeons. Only 13% tried to use hormone therapy aiming to induce testicular descent or to improve future fertility. The choices of various surgical techniques were noted. During laparoscopy, if vessels and cord structure were seen entering the ipsilateral internal inguinal ring, most respondents chose to explore the groin. On the other hand, should there was an absent or atrophic testis, the respondents were split on whether to perform a contralateral orchiopexy. Conclusion: This survey describes the current practices of a sample of pediatric surgeons and urologists in the management of intraabdominal testis. The use of hormonal treatment, timing of fixation and management in case of passing through vas and vessels through DIR were undisputable. However, management of low-lying and peeing testis together with the management of contralateral testis were still debatable.

Needlescopic Disconnection and Peritoneal Closure for Pediatric Inguinal Hernia Repair: A Novel Technique.

BACKGROUND: There are many laparoscopic techniques for pediatric congenital inguinal hernia repair. Needlescopic surgery was introduced recently in pediatric patients aiming at getting excellent cosmetic outcomes. PURPOSE: The aim of this study was to describe a novel technique for needlescopic inguinal hernia repair in children. PATIENTS AND METHODS: Needlescopic division of the hernial sac was carried out on 369 children in 6 pediatric tertiary centers during the period from August 2016 to May 2019. All hernias were repaired by a novel needlescopic procedure that replicates all the steps of the open herniotomy. RESULTS: A total of 369 patients with 410 hernias were included in this study. They were 232 (62.9%) males and 137 (37.1%) females, with a mean age of 3.58±1.26 (range=2 to 8 y) and mean internal inguinal ring diameter was 13.65±3.85 mm (range=8 to 20 mm). The mean operative time was 23.36±4.67 minutes for bilateral and 14.28±2.98 minutes for unilateral cases. All cases were completed without conversion to conventional laparoscopy. All cases were followed up for a mean of 19.6±3.2 months. None of our patients developed recurrence or testicular atrophy and the scars were nearly invisible 3 months postoperatively. CONCLUSIONS: Needlescopic pediatric inguinal hernia repair using disconnection of the hernia sac at internal inguinal ring with purse-string suture closure of peritoneum is feasible and safe with no recurrence and with outstanding cosmetic results.

Thoracoscopic Repair of Neonatal Congenital Diaphragmatic Hernia: Minimizing Open Repair in a Low-Income Country.

Aim: To assess the severity of persistent pulmonary hypertension (PPH) in congenital diaphragmatic hernia (CDH) neonates solely using oxygenation index (OI). Study Design: A prospective study was carried out from April 2016 to March 2019, where all confirmed CDH neonates were evaluated for the possibility repair through thoracoscopic approach. The severity of PPH was assessed using OI. It is calculated using the equation: mean airway pressure (MAP) × FiO2 × 100 ÷ PaO2. Neonates having OI <5 were considered to have a mild degree of pulmonary hypertension; hence, thoracoscopic repair was offered for them. Results: Thirty-nine CDH cases met the selection criteria; therefore, they underwent thoracoscopic repair. Primary diaphragmatic repair was successfully accomplished thoracoscopically in all neonates without any perioperative complications. Conversion from thoracoscopy to open method occurred in five cases. The causes were due to difficulties encountered during repair and none was due to a pure anesthetic problem or general deterioration during thoracoscopy. Recurrence had occurred in two cases only. Conclusion: OI is a reliable subjective parameter that could be used as an adjuvant to the usually used cardiovascular and pulmonary parameters for thoracoscopic repair decision. With increasing surgical experience, a wider range of neonates may be considered for thoracoscopic CDH repair.
