BACKGROUND Laparoscopic pyloromyotomy is associated with an increased risk of incomplete myotomy compared with open myotomy. We hypothesized that utilizing ultrasound measured length to direct laparoscopic pyloromyotomy would reduce the risk of incomplete pyloromyotomy without a concomitant increase in the risk of mucosal perforation. METHODS Infants (n=43) with hypertrophic pyloric stenosis ...

BACKGROUND Undetected perforation during laparoscopic pyloromyotomy can be fatal. Detecting a perforation at the time of laparoscopic pyloromyotomy is difficult. The purpose of this study was to determine whether air insufflation of the stomach reliably detects perforation during laparoscopic pyloromyotomy. CASE REPORTS Between 2007 and 2008, 71 patients underwent laparoscopic pyloromyotomy a...

Background. Although open Ramstedt's pyloromyotomy is the gold standard for the surgical management of infantile hypertrophic pyloric stenosis, laparoscopic pyloromyotomy has been found highly successful. Various factors, however, can affect the outcomes of surgical interventions in these patients. We observed a relationship between the number of ports used and outcome in patients undergoing la...

The objective of this study was to evaluate and compare laparoscopic pyloromyotomy methods involving the laparoscopic scalpel and the harmonic scalpel in pigs. The experiment was conducted on 4 subgroups of 12 animals subjected to laparoscopic-assisted pyloromyotomy with a surgical scalpel and the harmonic scalpel, as well as laparoscopic pyloromyotomy with Berci's laparoscopic scalpel and the ...

INTRODUCTION Pyloromyotomy is a pyloric drainage procedure routinely done during transhiatal esophagectomy (THE) to prevent delayed gastric emptying (GE) resulting from truncal vagotomy. However, controversy still surrounds the need for pyloric drainage following esophageal substitution with gastric conduit after esophagectomy. The aim of this study was to determine the usefulness of pyloromyot...

OBJECTIVES To calculate incidence rates of pyloric stenosis (estimated by the rate of pyloromyotomy) among infants in Ontario and determine their association with population sociodemographic indicators. METHODS Pyloromyotomy rates were calculated from hospital discharge data from 1993 through 2000. Four-year data (1993-1996 and 1997-2000) were combined to ensure the stability of the rates. Sm...

Previous studies of the pathogenesis of congenital hypertrophic pyloric stenosis (CHPS) have implicated immunoreactive gastrin, although no consistent relationship has been demonstrated. In this study we have examined the effect which pyloromyotomy has on serum and luminal gastrin concentration after a mechanical and protein stimulus. Seventeen infants were examined preoperatively, and 1 week a...

BACKGROUND Atropine has been used as a successful primary medical treatment for hypertrophic pyloric stenosis. Several authors have reported a higher rate of incomplete pyloromyotomy with the laparoscopic approach compared to open. In this study, we evaluated the use of atropine as a medical treatment for infants with emesis persisting greater than 48 hours after a laparoscopic pyloromyotomy. ...

OBJECTIVE Hypertrophic pyloric stenosis is a common pediatric surgical condition. A Ramstedt pyloromyotomy is performed either via laparotomy or laparoscopy. We report our first 25 cases of laparoscopic pyloromyotomy at an academic children's hospital. METHODS From January 2002 through February 2003, we retrospectively reviewed our first 25 laparoscopic pyloromyotomies. All patients had docum...

BACKGROUND Because of increased pressure to shorten hospital stays, some advocate discharging patients with pyloric stenosis within four hours of pyloromyotomy. Because some patients have persistent emesis after pyloromyotomy and thus require prolonged hospitalization to prevent dehydration, it would be helpful to be able to predict in which patients this will occur. METHODS We conducted a re...
