Fundoplication is a common surgical procedure for gastroesophageal reflux Disease (GERD). Recently the procedure has been performed with increased frequency laparoscopically. The aim of this study is to compare laparoscopic Nissen fundoplication (LNF) and open Nissen fundoplication (ONF) for GERD in children. We studied retrospectively the 88 pediatric patients who underwent the Nissen fundoplication for GERD as primary antireflux surgery from 1994 and 2009. ONF was performed in 34 cases and LNF was in 54 cases. 58 patients have neurologic impairment. Time to initial food intake after the surgery were reduced in the LNF group (p = 0.032).Recurrent GERD symptom occurred in one patient in LNF group and four patients in ONF group within 1 year after the surgery (p = 0.012). There were no statistically significant differences in post operative morbidity and mortality between both groups. In conclusion, our practice of Nissen fundoplication indicates that LNF takes priority in most pediatric patients.

Colonic atresia (CA) is the rare cause of intestinal obstruction, and diagnosis of CA is difficult. But only few research has been performed, so little information has been available. The purposes of this study was to analyze the clinical findings of CA so that help physicians make decision properly. Children with CA who were treated at the division of pediatric surgery at Asan Medical Center in the period from January 1989 to December 2011 were evaluated retrospectively. A total of 6 children were treated with CA. These accounted for 2.7% of all gastrointestinal atresias managed in Asan Medical Center. Only one child was premature and low birth weight, the others were fullterm neonates and showed normal birth weight. Vomiting and abdominal distension were common symptoms and simple X-ray and barium study were used for diagnose of CA. But only 66.7% of the babies were diagnosed as CA pre-operatively. And 2 children out of 6 underwent re-operation due to missed CA at the time of the first operation. In aspect of types of atresia, the type IIIa were two, type IV were two, type I was one case, and one child showed rectal stenosis due to rectal web. Various operations were done according to individual findings and associated diseases. The 50% (n=3) of children underwent the primary anastomosis and the others (n=3) underwent colostomy first and staged operation later for missed CA or associated disease. All of them were recovered any significant complications. Therefore, the prognosis of CA is satisfactory if diagnosis and surgical management could be made properly. But because of the low incidence of CA, delay of diagnosis and treatment may occur. To prevent delay of diagnosis, we suggest prompt evaluation of doubtful infant and careful inspection of distal patency of bowel including whole colon and rectum when operating patients with intestinal atresia at any level.

In one-stage transanal endorectal pull-through operation (TERPT) for Hirschsprung disease, preoperative evaluation by contrast enema (CE) is important tool in aspect of planning of surgical procedure as well as diagnosis. This study was to evaluate the significance of CE for identifying the extent of aganglionic bowel. A retrospective analysis was performed in 40 patients who underwent TERPT between 2003 and 2011. The authors reviewed the CE studies and their correlation with pathologic extent of aganglionosis. Total 66 contrast enemas were performed in 40 patients. Twenty patients underwent single CE, but 20 patients required multiple CEs. In single CE group, 17 had clear radiographic transition zone, but 3 had less definite transition zone. In multiple CE group, 17 patients who had equivocal finding in first or second CE had definite radiographic transition zone, but 3 patients of this group had less definite radiographic transition zones. Overall, 34 patients (85%) had clear radiographic transition zone by single or repeated CE. One (2.9%) out of 34 patients with clear radiographic transition zone had discordance between radiographic and pathologic transition zone. In contrast 4 (66.7%) out of 6 patients with equivocal radiographic transition zone had discordance between radiographic and pathologic transition zone. Observation of clear radiographic transition zone is important in preparation of TERPT, and repeated CE is helpful to reduce the discordance between radiographic and pathologic transition zone. Awareness of the possibility of discordance is also important if radiographic transitional zone is not clear.

Acute appendicitis is very rare in premature neonates. Preoperative diagnosis of this condition is difficult, and then it leads to high morbidity and mortality. We report 9-day-old premature male with ruptured acute appendicitis presented with pneumoperitoneum on plain films of the abdomen. Awareness of this rare condition and possible differential diagnosis in this age group is also discussed.
