Article Synopsis
  • * A review of nine randomized controlled trials (RCTs) involving 529 patients indicated no significant differences in mortality, anastomosis leakage, respiratory issues, or vomiting, though results regarding gastric emptying time (GET) presented mixed findings.
  • * The study suggests that pyloric drainage is not essential in these operations, but emphasizes the need for further research, especially in European contexts, to draw more definitive conclusions.

Efficacy of gastric stimulator as an adjunct to pyloroplasty for gastroparesis: characterizing patients suitable for single procedure vs dual procedure approach.

J Gastrointest Surg

Electronic address:

Background: Pyloroplasty is an effective surgery for gastroparesis. However, some patients fail to improve after pyloric drainage and may require subsequent gastric electric stimulation. There is a paucity of data on the efficacy of gastric stimulator as an adjunct to failed pyloroplasty.

Background: Intraoperative pyloric drainage in esophagectomy may reduce delayed gastric emptying (DGE) but is associated with risk of biliary reflux and other complications. Existing evidence is heterogenous. Hence, this meta-analysis aims to compare outcomes of intraoperative pyloric drainage versus no intervention in patients undergoing esophagectomy.

Purpose: Surgical pyloroplasty or pyloromyotomy are often performed during esophagectomy with a view of improving gastric conduit drainage. However, the clinical importance of this is not clear, and some centers opt to omit this step. The aim of this meta-analysis is to compare the rates of pulmonary complications, anastomotic leak, mortality, delayed gastric emptying, and the need for further pyloric intervention, in patients undergoing esophagectomy with and without a drainage procedure.

Nasogastric tube drainage and pyloric intervention after oesophageal resection: UK practice variation and effect on outcomes.

Eur J Surg Oncol

May 2022

Department of General Surgery, Guy's and St Thomas' NHS Trust, London, UK; School of Cancer and Pharmaceutical Sciences, King's College London, London, UK; Department of Molecular Medicine and Surgery, Karolinska Institutet, Stockholm, Sweden. Electronic address:

Background: Over 1500 patients with oesophageal cancer undergo a resection in the UK each year. At surgery, patients commonly have a nasogastric tube (NGT) placed and may undergo a pyloric intervention. There is conflicting evidence on the use of both NGTs and pyloric interventions during oesophageal resections.
