Background: Although various anastomotic techniques and suture materials have been used in esophageal anastomosis, anastomotic leakage and stenosis are still somewhat frequent and serious complications when compared to other intestinal anastomoses. We have used interrupted single-layer suture technique using monofilament polypropylene suture in various esophageal anastomoses, including repair of the esophageal atresia, since 1990. Methods and method: We retrospectively evaluated the efficacy of this technique on postoperative leakage and stenosis in several esophageal reconstructions. The esophageal reconstructions using this technique were performed in 90 patients at Dong-A University Hospital from April 1990 through December 1996. Results: Anastomotic leakage occurred in 5 patients(5.6%) with one operative death. Stenosis at the anastomotic site occurred in 15 patients(n=86, 17.4%), which was most common in esophagogastrostomy(22%) and least common in esophagocolostomy (5%). This result was comparable to other methods including the autosuture technique. Conclusions: We concluded that this suture technique in esophageal anastomosis can be used with reasonable results in various esophageal reconstructions including correction of the esophageal atresia.

The results of hepatic portojejunostomy in 34 patients with biliary atresia operated upon by one surgeon between May 1989 and December 1997 were analyzed. Eleven (32.3 %) patients were 60 days or younger, 14 patient (41.2 %) were between 60 and 90 days, and 9 (26.5 %) were over 90 days of age. Jaundice cleared in 20 cases (58.8 %). Three patients died of liver insufficiency, 2 were anicteric but died from esophageal variceal bleeding. Three patients died as a result of sepsis, heart failure and left kidney agenesis. Five patients were lost to follow-up. The five-year survival rate was 73.8 %. Two patients over 90 days of age, survived more than 5 years. Survival rates were not significantly related to the age at operation. We conclude that hepatic portojejunostomy should be considered as a primary surgical modality for biliary atresia, even at age 90 days or more. Early detection of esophageal varices and sclerotherapy may be necessary. Liver transplantation is necessary if hepatic failure develops.

This study reviews 14 years' experience treating esophageal atresia with special emphasis on the clinical profile and outcome. From May 1989 to February 2003, 65 cases of esophageal atresia (EA) were treated at Asan Medical Center. Boys outnumbered girls 2.4 to 1. Prematutity and low birth weight were 27.7% and 38.5%. Esophageal atresia with distal tracheoesophageal fistula (TEF) was the most common type (87.7%), followed by pure EA and H type fistula. Forty-six patients (70.8%) had one or more associated anomalies, cardiac malformations were the most common. Duodenal atresia was found in 7 cases. There were 6 patients (9.2 %) with VATER cluster. VACTERL cluster was present in 18 patients (27.7%), one of who fulfilled the complete syndrome. Waterston group A, B and C made up 21.5%, 40.0% and 38.5% of the total group. Surgical treatment was attempted in 63 patients and deferred in 2 who had severe associated malformations. For EA with distal TEF, primary esophago esophagostomy was carried out in 51 cases, and division of TEF and gastrostomy in 4 cases and no operation in 2 cases. For pure EA, colonic graft was done in 2 after gastrostomy and esophagostomy, and esophago esophagostomy was performed in 2 after gastrostomy. Two patients with pure EA are waiting for the second operation after gastrostomy. Division of TEF was carried out in 2 cases with H type TEF. The overall survival rate was 76.9%, and survival by Waterston classification was 100% in group A, 80.8% in B and 60.0% in C. Thorough workup for associated anomalies, interdepartmental approach and more careful surgical decision and technique are required to improve the outcome of EA.

Eleven children with gastroesophageal reflux disease underwent fundoplication. Eight had neurological impairment, two had hiatal hernias and one had a history of esophageal repair for esophageal atresia. The most common and significant symptom was vomiting(81.8 %), followed by recurrent respiratory infections(72.7 %) and failure to thrive(72.7 %). The most common diagnostic tool was 24 hour esophageal pH study, which showed pH less than 4 for more than 10 % of the total recorded time in 6 of 9 patients. Nissen fundoplication was performed in 10 patients. Thal fundoplication was carried out in one patient with esophageal atresia. Stamm gastrostomy was added for nutritional and/or swallowing problem in all 8 patients with neurological impairment. The median follow up period was 13 months. There was one late death of unrelated cause and one recurrence. The quality of life after antireflux surgery was greatly improved. Antireflux surgery should be done if indicated, and a simultaneous gastrostomy considered in a patient with neurological impairment.
