Thoracoscopic esophagoesophagostomy for a refractory stricture in a patient with esophageal atresia.

Anastomosis stricture is a well-known complication after esophageal atresia repair. Endoscopic dilatation is the gold standard treatment for esophageal stenosis. However, surgical interventions are indicated for refractory cases. We present a 2-year-old girl with esophageal stricture refractory to regular endoscopic dilatation after esophageal atresia repair that underwent thoracoscopic stricture resection and reanastomosis. Although thoracoscopic approach is widely used for esophageal atresia repair, this approach has not been used before for the treatment of anastomosis stricture.

Thoracoscopic approach for complications after esophageal atresia repair: initial experience.

INTRODUCTION: Improvements in technology and health care have helped reduce morbidity and mortality in patients with esophageal atresia. However, postoperative complications such as dehiscences, strictures, and recurrent fistulas still occur in a large percentage of patients. Here, we present our initial experience using the thoracoscopic approach for complications after esophageal atresia repair. METHODS: We retrospectively analyzed the medical records of patients who developed complications after esophageal atresia repair and underwent thoracoscopic reoperation at two centers. Anastomotic leakage, anastomotic stricture, and recurrent tracheoesophageal fistula were assessed as complications after esophageal atresia repair. RESULTS: We reoperated on four patients (range of age 3 days - 2 years) by thoracoscopy. Two patients who had undergone thoracoscopic atresia repair presented with anastomotic dehiscence. The anastomoses were thoracoscopically reconstructed without tension. One patient had undergone thoracoscopic atresia repair presented with esophageal stricture refractory to endoscopic dilatations. Thoracoscopic esophagoesophagostomy was performed in this 2-year-old patient. One patient who had undergone esophageal atresia repair and tracheoesophageal fistula closure by thoracotomy presented with a recurrent fistula at 1 year of age. The patient underwent thoracoscopic fistula closure with a 5-mm endostapler. All patients remain asymptomatic after reoperation. CONCLUSIONS: Reoperation after esophageal atresia repair is challenging and carries a relatively high risk of developing complications. Compared to conventional surgery, the thoracoscopic approach in experienced hands offers better visualization and more accurate dissection and drainage of the thoracic cavity. Therefore, we want to encourage the use of thoracoscopy in the treatment of complications after esophageal atresia repair.

The Accuracy of Silk Glove Sign Compared with Inguinal Bulge in the Diagnosis of Indirect Inguinal Hernia in Children.

Introduction: The diagnosis of indirect inguinal hernia is usually based on clinical grounds. Physical examination generally showed an inguinal bulge. However, when no bulge is seen, the silk glove sign (SGS) or palpating the processus vaginalis over the pubic tubercle can be useful. The aim of our study is to compare the accuracy of the presence of inguinal bulge with the presence of SGS. Materials and Methods: We conducted a retrospective of all patients undergoing laparoscopic inguinal hernia repair between January 2002 and November 2015. Preoperative diagnosis was obtained by physical examination. The presence of an inguinal bulge or SGS was considered diagnostic of indirect inguinal hernia. Intraoperative diagnosis was made to laparoscopic findings. The sample was divided into two groups: group 1 including the patient with inguinal bulge and group 2 including those with SGS. Results: A total of 1024 inguinal canals were evaluated. Inguinal bulge was observed in 379 inguinal canals (group 1), whereas SGS was detected in 196 (group 2). There were statistically significant differences between both groups regarding gestational age, birth weight, surgical age, and surgical weight. Prematurity and previous episodes of incarceration were statistically more common in group 1 (P < .001). The positive predictive value in group 1 was 98.7%, whereas in group 2 was 86.73% (P < .001). Conclusions: Although we have found that the success rate for accurate diagnosis is higher in patients with inguinal bulge, SGS can be useful in detecting indirect inguinal hernia.

Thoracoscopic recurrent tracheo-oesophageal fistula repair with mini endostapler: promising solution.

Recurrent tracheo-oesophageal fistula (TOF) is a common complication in children who underwent oesophageal atresia repair. The traditional surgical approach performed either by thoracotomy or cervicotomy is associated with a high rate of morbidity, mortality and new recurrence. In the last decades, endoscopic techniques have emerged as the minimally invasive alternative. However, it seems that the optimal treatment is still unknown. We present a patient with a recurrent TOF who underwent thoracoscopic closure using a 5.8 mm endostapler. The patient was extubated at the end of the procedure, and he started feeding the day after surgery. At 15 months of follow-up, he is asymptomatic. Thoracoscopic closure of TOF using endostaplers seems to be a safe alternative with some possible benefits compared with traditional and endoscopic approach.

Association between gallbladder agenesis and choledochal cyst: cause or coincidence?

This case report describes an extremely rare association between gallbladder agenesis and choledochal cyst (CC). A 9-year-old girl presented with recurrent abdominal pain in the right upper quadrant. Radiological studies revealed a CC type IVa and an agenesis of gallbladder and cystic duct. Due to the possibility of biliary neoplasm, the patient underwent cyst resection and hepaticoduodenostomy. Histopathological findings showed inflamed fibrous tissue covered by biliary epithelium with no evidence of malignancy.

Is the Laparoscopic Approach Safe for Inguinal Hernia Repair in Preterms?

Introduction: Although laparoscopic inguinal hernia repair in children has gained popularity in the last decades, this approach remains uncommon in preterm infants. The aim of this study was to compare the characteristics and the outcomes of indirect inguinal hernias in term and preterm infants. Material and Methods: From January 2002 to November 2015, all charts of the pediatric patients who underwent laparoscopic indirect inguinal hernia repair in one single institution within the first 6 months of life were revised. The data of 156 patients were analyzed retrospectively. Patients were divided in two groups: group I, including the preterm patients, and group II, including the term patients. Results: A total of 90 preterm infants and 66 term infants were included. In the group I, preoperative diagnosis was right-sided inguinal hernia in 20% of patients, left sided in 22.2%, and bilateral in 57.5%; while in the group II, preoperative diagnosis was right-sided inguinal hernia in 42.4% of infants, left sided in 15.2%, and bilateral in 42.4% (P = .01). In group I intraoperative diagnosis was right-sided inguinal hernia in 10% of patients, left sided in 16.7%, and bilateral in 73.3%; while in the group II, intraoperative diagnosis was right-sided inguinal hernia in 25.8% of infants, left sided in 12.1%, bilateral in 60.6%, and there was no hernia in one patient (P = .02). However, there was no statistically significant difference in the correct intraoperative diagnosis between both groups (P = .59). No statistical significance was observed between the two groups regarding postoperative complications. Conclusions: Bilateral inguinal hernia is more frequent in preterm infants compared to term infants, whereas the incidence of right-sided inguinal hernia is higher in term patients. Laparoscopic inguinal hernia repair in preterm infants seems to be safe and effective.

Wilkie's syndrome in monozygotic twins treated by 3-D laparoscopic duodenojejunostomy.

Superior mesenteric artery syndrome, also known as Wilkie's syndrome, is a rare cause of proximal duodenum obstruction in children. Here, we describe the first pediatric case of superior mesenteric artery syndrome in monozygotic twin brothers. Both patients underwent 3-D laparoscopic duodenojejunostomy at the same age with an uneventful recovery.

Is the laparoscopic approach appropriate for pediatric subhepatic appendicitis?

INTRODUCTION: Subhepatic appendicitis in children is an unusual condition that can be challenging for the pediatric surgeons to treat. The aim of our study was to compare the outcomes of laparoscopic appendectomies based on the position of the appendix. METHODS: The data of 1736 patients who had undergone laparoscopic appendectomy in our tertiary center were retrospectively reviewed. We compared two groups: subhepatic location (n = 56) and non-subhepatic location (n = 1680). A P-value of less than 0.05 was considered statistically significant. RESULTS: There was no statistically significant difference between the demographic variables of the groups. More than half of the subhepatic appendicitises were gangrenous (44.6%) or perforated (16.1%), whereas most of the non-subhepatic appendicitises were phlegmonous (56.9%). Extracorporeal ligation of the appendix was the preferred technique in both the subhepatic and non-subhepatic groups (69.6% and 89.8%, respectively). The subhepatic group had a statistically significant higher incidence of technical difficulties (1.6%) and abdominal drain (18.6%) than the non-subhepatic group, as well as a longer operative time and hospital stay. However, intraoperative and postoperative complications were similar in both groups. CONCLUSION: Laparoscopic subhepatic appendectomy is safe and does not lead to increased complications. However, the technique is made difficult by the fact that the appendix is an atypical location, and the rate of complicated appendicitis is higher.

Laparoendoscopic single-site nephrectomy in children: Is it a good alternative to conventional laparoscopic approach?

BACKGROUND: Minimally invasive surgery is considered to be the gold standard treatment for nephrectomy in children. In recent decades it has been proposed that laparoendoscopic single-site (LESS) surgery is a feasible alternative to perform laparoscopic nephrectomies. OBJECTIVE: The aim of our study was to compare the safety and efficacy of LESS against conventional laparoscopic (CL) nephrectomy. STUDY DESIGN: From March 2010 to November 2012 charts of pediatric patients who underwent laparoscopic nephrectomy at our tertiary center were revised. The data from 23 nephrectomies performed by either LESS or conventional laparoscopic approach were analyzed retrospectively. A transperitoneal approach was selected for both modalities. Indications for surgery included multicystic dysplastic kidneys (MCDK), hydronephrosis, vesicoureteral reflux (VUR), and renal dysplasia. Malignancy and previous abdominal interventions were exclusion criteria. Differences with a p value less than 0.05 were considered to be statistically significant. RESULTS: Twenty-three laparoscopic nephrectomies were performed, 13 by CL (53.5%) and 10 by LESS (46.5%). The mean age of patients was 3.29 ± 3.5 years. There were no significant differences in age, gender, laterality of pathology, size of the kidneys, and surgical indications between the groups (p = 0.067, 0.431, 0.94, 0.644, and 0.078, respectively). The mean operative times were 120 min for LESS and 132.7 min for CL (p = 0.334). No procedures required conversion to open surgery or to standard laparoscopy. There was one intraoperative complication in each group (p = 0.845). The mean length of stay (LOS), narcotic usages, and postoperative complications were similar in both groups. DISCUSSION: To overcome technical difficulties of the LESS approach, articulated tools have been developed. However, they may be not suitable for use with younger children. Although we performed LESS nephrectomies with conventional laparoscopic instruments, in our study, LESS and CL approach were comparable in terms of operative time, analgesic therapy, LOS, and complications. CONCLUSIONS: LESS nephrectomy for benign kidney diseases performed by skilled laparoscopic surgeons is safe and comparable with CL technique in pediatric patients. However, although minimally invasive development pushes towards "a scar-free surgery" (see Figure), these approaches have been performed in only a few centers in the world. Prospective studies comparing both approaches are necessary to verify the advantages of LESS nephrectomy in children.

Pediatric femoral hernia in the laparoscopic era.

INTRODUCTION: Femoral hernia is a rare and often misdiagnosed condition in childhood. The aim of our study was to demonstrate that the laparoscopic approach improves diagnostic accuracy and offers a safe and effective treatment. METHODS: A retrospective study of 687 pediatric patients who underwent laparoscopic inguinal hernia repair from January 2000 to December 2015 was performed. RESULTS: Femoral hernias were identified in 16 patients (2.3%). The right side was affected in 10 cases (62.5%), the left side in 5 (31.2%), and 1 case was bilateral (6.2%). The mean age of patients was 8.00 ± 3.81 years, and there was a male predominance. Preoperative diagnosis was femoral hernia in eight cases (50%) and indirect inguinal hernia in the remaining eight (50%). Seven children (43.8%) presented with hernia recurrence after having undergone an open ipsilateral indirect hernia repair. A modified laparoscopic McVay technique was performed in 12 cases (70.6%). An epigastric artery injury by trocar occurred in one patient. All operations were completed laparoscopically. The mean surgical time was 45.6 ± 22.9 min for unilateral cases and 110 ± 10.0 min for bilateral cases. No immediate postoperative complications were noted. The mean postoperative hospital stay was 0.6 ± 0.4 days. No recurrence was observed after a median follow-up of 11 years (range, 4-16 years). CONCLUSION: Femoral hernia is a rare pathology in pediatric patients that is often difficult to diagnose. The laparoscopic approach is effective in the diagnosing and treating these hernias, and it allows for the simultaneous repair of multiple groin defects.
