title: Repair of mucosal perforation during pyloromyotomy: surgeon's choice.
abstract: Mucosal perforation during Fredet-Ramstedt pyloromyotomy traditionally has been repaired with muscular and mucosal reapproximation, pyloric rotation, and repeat myotomy. The purpose of this study was to determine whether simple mucosal closure is a safe alternative repair technique for such a perforation. The authors reviewed their experience of pyloromyotomies over a 21-year period and found a 1.67% incidence (15 of 896) of mucosal perforation. Four of these patients had repair with rotation and repeat myotomy, and 11 had repair with primary mucosal approximation. The patients were compared with respect to demographics, duration of operation, postoperative feeding intolerance, time from operation until discharge, and postoperative complications. No differences were noted between the two groups. Interestingly, when the perforation group (n = 15) was compared with the nonperforation group (n = 881), the mean age at time of pyloromyotomy was significantly higher for the group with perforation 48 days v 34 days; P = .0021, Student's t test). The authors conclude that those most likely to suffer mucosal perforation during pyloromyotomy are older patients with pyloric stenosis. Such mucosal perforation can be repaired with equal efficacy and safety using the traditional pyloric rotation approach or primary mucosal closure.
