Infantile hypertrophic pyloric stenosis: a comparative study of pyloric traumamyoplasty and Fredet-Ramstedt pyloromyotomy.

Purpose: The aim of this study was to compare the incidence of surgical complications (duodenal perforation, postoperative vomiting, wound infection or dehiscence, incisional hernia) between 2 different surgical techniques for the resolution of hypertrophic pyloric stenosis in children.

Methods: A clinically controlled, randomized study with follow-up from 24 to 36 months was conducted. One hundred children between 15 days and 2 months old, who underwent surgical resolution of hypertrophic pyloric stenosis, were put randomly into 2 groups: I, pyloric traumamyoplasty (n = 43); II, Fredet-Ramstedt pyloromyotomy (n = 57).

Intestinal anastomosis in children: a comparative study between two different techniques.

Purpose: The aim of this study was to compare the incidence of surgical complications between two different surgical techniques for intestinal anastomosis in children.

Methods: This was a clinically controlled, randomized study with blind follow-up from 18 to 36 months performed at the Reference Government Hospital in Mexico City. Eighty-six children required intestinal anastomosis, ages ranged between 1 month and 16 years, with emergency or elective surgery.
