Intraoperative Pyloric Interventions during Oesophagectomy: a Multicentre Study.

Area of Science:

• Gastroenterology
• Surgical Oncology
• Clinical Trials

Background:

• Delayed gastric emptying (DGE) is a common complication following oesophagectomy, primarily attributed to pyloric denervation.
• Previous research on pyloric management during oesophagectomy has yielded conflicting results.
• This multicenter study aimed to compare outcomes of different pyloric interventions.

Purpose of the Study:

• To evaluate the efficacy of intra-pyloric botulinum toxin injection and pyloroplasty compared to no pyloric treatment in managing DGE after oesophagectomy.
• To identify the optimal approach for pyloric management to improve patient outcomes.

Main Methods:

• A prospective database identified 90 patients undergoing oesophagectomy for malignancy.
• Patients were stratified into three groups: botulinum toxin injection, pyloroplasty, or no pyloric treatment.
• Key outcome measures included nasogastric tube duration, need for endoscopic intervention, hospital stay, mortality, and DGE symptoms.

Main Results:

• Postoperative nasogastric tube duration was significantly longer in the botulinum toxin group (p=0.001).
• Patients receiving botulinum toxin also required more endoscopic pyloric interventions (p=0.032 inpatient, p=0.003 outpatient).
• No significant differences were observed in other measured outcomes between the groups.

Conclusions:

• Surgical pyloroplasty and intra-pyloric botulinum toxin injection did not demonstrate superiority over no pyloric treatment for preventing DGE post-oesophagectomy.
• The findings suggest that no specific intervention on the pylorus may lead to the most favorable outcomes regarding DGE.
• Further research may be warranted to confirm these findings and explore underlying mechanisms.
