Scarless laparoscopic repair of epigastric hernia in children.

BACKGROUND: Despite the small size of the incision, the scar left by open repair of epigastric hernia in children is unaesthetic. Few laparoscopic approaches to epigastric hernia repair have been previously proposed, but none has gain wide acceptance from pediatric surgeons. In this study, we present our experience with a scarless laparoscopic approach using a percutaneous suturing technique for epigastric hernia repair in children. METHODS: Ten consecutive patients presenting with epigastric hernia 15 mm or further from the umbilicus were submitted to laparoscopic hernia repair. A 5-mm 30º-angle laparoscope is introduced through a umbilical trocar and a 3-mm laparoscopic dissector is introduced through a stab incision in the right flank. After opening and dissecting the parietal peritoneum, the fascial defect is identified and closed using 2-0 polyglactin thread through a percutaneous suturing technique. Intraoperative and postoperative clinical data were collected. RESULTS: All patients were successfully submitted to laparoscopic epigastric hernia repair. Median age at surgery was 79 months old and the median distance from the umbilicus to the epigastric defect was 4 cm. Operative time ranged from 35 to 75 min. Every hernia was successfully closed without any incidents. Follow-up period ranges from 2 to 12 months. No postoperative complications or recurrence was registered. No scar was visible in these patients. CONCLUSION: This scarless laparoscopic technique for epigastric hernia repair is safe and reliable. We believe this technique might become gold standard of care in the near future.

Transesophageal pulmonary lobectomy with single transthoracic port assistance: study with survival assessment in a porcine model.

BACKGROUND AND STUDY AIMS: Thoracoscopic pulmonary lobectomy is being performed in an increasing number of patients. The aims of the current study were to assess natural orifice transluminal endoscopic surgery (NOTES) as an alternative to transthoracic endoscopic surgery, and to test the feasibility of peroral transesophageal right upper pulmonary lobectomy with the assistance of a single transthoracic trocar. METHODS: In 10 acute and 4 survival pigs, right upper pulmonary lobectomy was performed using a forward-viewing double-channel gastroscope and an operative thoracoscope with a 5-mm working channel inserted through a single transthoracic 12-mm) port. Time, safety, and feasibility of the following steps were recorded in all animals: esophagotomy, hilar dissection, individual ligation of the hilum elements, pulmonary lobectomy, and specimen retrieval. In the survival experiments, esophagotomy was closed using a reticulated laparoscopy suture device and an esophageal stent was placed. These animals were kept alive and monitored for 2 weeks. RESULTS: Esophagotomy was performed safely in all animals (mean procedure duration 5.4 ± 1.7 minutes). Dissection of the right upper lobe hilum elements (bronchus, arteries, and veins) was carried out without adverse events. Individual ligation of the hilum elements was performed in all but two cases (time for dissection and ligation 44.2 ± 14.8 minutes). Lobectomy and specimen retrieval were completed in all animals (9.5 ± 3.1 minutes). Esophagotomy closure and stent placement were carried out in 20.0 ± 2.8 minutes in the survival animals. These animals fed normally and gained weight postoperatively without signs of disease. Endoscopic examination before necropsy revealed a pseudo-diverticulum in one animal, and wound dehiscence with confined collection/recess in the remaining animals. CONCLUSIONS: Transesophageal right upper pulmonary lobectomy using single transthoracic trocar assistance is feasible and may represent a step towards scar-free pulmonary lobectomy.

9 Years after the first laparoscopic adjusted gastric banding (LAGB) in adolescents: the Portuguese experience.

INTRODUCTION: Children all over the world are increasingly becoming overweight and obese. The experience with adults has demonstrated that surgery is the only effective way of achieving sustained weight loss in obese patients. Simultaneously, it has been proposed that bariatric surgery in the adolescent period would be a more effective treatment for childhood-onset extreme obesity rather than delaying surgery for extremely obese youth until adulthood. Nevertheless, the optimal surgical option for both adults and adolescents has yet to be established. The aim of our study was to evaluate the results of 9 years of laparoscopic adjusted gastric banding (LAGB) performed in our hospital for obesity-associated comorbidities (OAC), weight loss and surgical morbidity. METHODS: A prospective study of all patients who underwent LAGB at our hospital between July 2001 and May 2010 was carried out. Patient selection was by a multidisciplinary team and based on the "IPEG Guideline for the Surgical Treatment of Extremely Obese Adolescents". Data were reviewed retrospectively. RESULTS: 14 patients underwent LAGB (10♀; 4♂; average age: 16 years). Preoperative BMI ranged between 41.4 and 54.6 kg/m (2). Prior to surgery, 8 different OACs were identified. 6 months later, 4 types of OAC had resolved completely and the other 4 had improved, and the improvement was maintained over time. The average excess weight (EW) loss increased from 25.7 to 48.2% at 6 and 36 months of follow-up, respectively (10 patients). At 60 and 106 months of follow-up it was 41.5% (5 patients) and 31.8% (1 patient), respectively. There were no complications arising from the surgery itself. Long-term complications were few and easily managed. CONCLUSIONS: LAGB seems to be a good option to treat obese adolescents, as it is a minimally invasive procedure that does not radically change the patient's anatomy and is associated with minimal morbidity. It leads to a sustained improvement/resolution of OAC, and although weight loss is not continuous, it is maintained over time.

Bilateral submandibulectomy for the treatment of drooling in children with neurological disability.

AIM OF THE STUDY: Drooling is common in children with neurological disabilities (ND), and constitutes an additional burden with many medical complications in an already socially disadvantaged patient. This study aims to evaluate the effectiveness of bilateral submandibulectomy (BS) to treat drooling with regard to the parental satisfaction grade, complications and recurrence of drooling in children with ND. PATIENTS/MATERIAL AND METHODS: A retrospective study was performed of all children with ND and drooling who underwent BS in our Department between January 1996 and November 2008. Data were taken from surgical records and patient files. Parental satisfaction was graded into four classes: A: 75-100% satisfaction (infrequent drooling, small amounts; absence of drooling); B: 50-75% satisfaction (occasional drooling, on and off all day; infrequent drooling, small amounts); C: 25-50% satisfaction (frequent drooling, but not profusely; occasional drooling, on and off all day); D: 0-25% satisfaction (constant drooling, always wet; frequent drooling, but not profusely). RESULTS: BS was performed in 85 patients (38% male; 62% female; median age, 9 years). 35 patients had to be excluded from our study because their medical records were unavailable. Only 3 out of the remaining 50 patients had recurrence. Parental satisfaction grade (PSG) was A in 26 cases (55.3%); B in 15 (31.9%); C in 3 (6.4%) and D in 3 (6.4%). The first follow-up was usually 1 week after surgery (median, 2 weeks). The incidence of post-surgery complications was 4% and all complications were minor. DISCUSSION/CONCLUSIONS: Assessment of the results achieved was subjective as it was not possible to quantify the amount of drooling precisely before/after surgery. Nevertheless, BS was found to be an easy and safe procedure as the low rate of complications demonstrates. It was also found to be an effective procedure; there were only 3 recurrences, and PSG in 87.2% of cases was either A or B, indicating a minimum improvement in drooling of 50%.
