A benign anastomotic stricture is a common complication of upper gastrointestinal (UGI) surgery and is difficult to manage conservatively. Fluoroscopically guided balloon dilation has a number of advantages and is a safe and effective procedure for the treatment of various benign anastomotic strictures in the UGI tract.

BACKGROUND/AIMS: Endoscopic papillary balloon dilation (EPBD) is a safe and effective method for the treatment of choledocholithiasis, but previous studies have rarely reported the appropriate ballooning time (BT). We prospectively evaluated the safety and efficacy of EPBD according to BT in patients undergoing bile duct stone removal. METHODS: Seventy consecutive patients with bile duct stones were randomly assigned to receive EPBD with either conventional (n = 35, 60 seconds) or short (n = 35, 20 seconds) BT. RESULTS: EPBD alone achieved complete bile duct clearance in 67 patients (long BT, n = 33, 94.3%; short BT, n = 34, 97.1%; p = 0.808). We also found no significant difference in the rate of complete duct clearance, including procedures that used mechanical lithotripsy, between the long and short BT groups (97.1% vs. 100%; p = 0.811). Mild pancreatitis was noted in four (11.4%) patients in the long BT group and two (5.7%) patients in the short BT group, but this incidence was not significantly different. CONCLUSIONS: The study showed that EPBD using both 20-sec and 60-sec BTs is safe and effective for the treatment of bile duct stones. Short and long BTs produced comparable outcomes.

OBJECTIVE: We wanted to evaluate the therapeutic efficacy of the percutaneous balloon dilatation and large profile catheter maintenance method for the management of patients with anastomotic biliary strictures following liver transplant. MATERIALS AND METHODS: From May 1999 to June 2003, 12 patients with symptomatic benign biliary stricture complicated by liver transplantation were treated with the percutaneous balloon dilatation and large profile catheter maintenance method (1-6 months). The patients were eight males and four females, and their ages ranged from 20 to 62 years (mean age: 44 years). Ten patients underwent living donor liver transplantation and two underwent cadaveric liver transplantation. Postoperative biliary strictures occurred from two to 21 months (mean age: 18 months) after liver transplantation. RESULTS: The initial technical success rate was 92%. Patency of the bile duct was preserved for eight to 40 months (mean period: 19 months) in 10 of 12 (84%) patients. When reviewing two patients (17%), secondary balloon dilatations were needed for treating the delayed recurrence of biliary stricture. In one patient, no recurrent stenosis was seen during the further 10 months follow-up after secondary balloon dilatation. Another patient did not response to secondary balloon dilatation, and he was treated by surgery. Eleven of 12 patients (92%) showed good biliary patency for 8-40 months (mean period: 19 months) of follow-up. CONCLUSION: The percutaneous balloon dilatation and large profile catheter maintenance method is an effective therapeutic alternative for the treatment of most biliary strictures that complicate liver transplantation. It has a high success rate and it should be considered before surgery.

PURPOSE: We report herein major determinants and long- term outcomes of balloon dilatation (BD) for 27 pediatric patients with isolated native valvular pulmonary stenosis (VPS). MATERIALS AND METHODS: From May 1997 to May 2003, 27 pediatric patients with VPS (pressure gradients> or =40mmHg) were enrolled in this retrospective study. Single-balloon maneuver was applied in 26 patients, and double- balloon maneuver in 1. After BD, the pressure gradients were documented simultaneously by pullback maneuver by cardiac catheterization and echocardiography within 24 hours, at 1- month, 3-month, 1-year, and 4-to-10-year follow-ups. RESULTS: Before BD, the echocardiographic gradients ranged from 40 to 101mmHg (61+/-19, 55), and from 40 to 144mmHg (69+/-32, 60) by pressure recordings. After BD, the gradients ranged from 12 to 70mmHg (29+/-13, 27) by pressure recording (p<0.001), and from 11 to 64mmHg (27+/-12, 26) by echocardiography within 24 hrs (p<0.001). The ratios of the systolic pressure of the right ventricle to those of the left ventricle were 55 to 157% (89+/-28, 79%) before BD, and 30 to 79% (47+/-13, 42%) after BD p<0.001). Follow-up (7.7+/-5.7, 4.5 years) echocardiographic gradients ranged from 11 to 61mmHg (25+/-11, 24). Two patients did not have immediate success owing to infundibular spasm. Improved right ventricular compliance could be accounted for the ultimate success in these 2 patients. The ultimate successful rate was 100%. CONCLUSION: BD can achieve excellent long-term outcomes in the pediatric patients with isolated native VPS.
