Oesophagogastrectomy with an anastomosis using linear staplers

Area of Science:

• Gastroenterology
• Surgical Oncology
• Surgical Innovation

Background:

• Oesophagogastrectomy often leads to dysphagia due to fibrous stricture formation at the anastomosis.
• This complication occurs in up to one-third of patients, diminishing the palliative benefits of surgery.
• Alternative techniques are needed to prevent strictures and improve swallowing function post-surgery.

Purpose of the Study:

• To evaluate a novel oesophagogastric anastomosis technique using linear staplers.
• To determine if this technique can eliminate postoperative fibrous stricture formation.
• To compare the outcomes of linear stapled anastomosis with traditional circular stapled or sutured methods.

Main Methods:

• Retrospective analysis of 111 patients undergoing oesophagogastrectomy between 1980 and 1991.
• Utilized linear staplers for oesophagogastric anastomosis in all patients.
• Compared cadaveric models of linear stapled anastomoses with circular stapled anastomoses.

Main Results:

• The linear stapler technique resulted in no cases of benign stricture formation.
• Reported leak rate was 2.7%, with 30-day and hospital mortality rates of 5.4% and 8.1%, respectively.
• Cadaveric models showed larger cross-sectional areas for linear stapled anastomoses, indicating reduced stricture risk.

Conclusions:

• Linear stapler anastomosis is a safe and effective technique for oesophagogastrectomy.
• This method significantly reduces or eliminates the risk of benign fibrous stricture formation.
• Linear stapler anastomosis should be considered the preferred technique for oesophagogastric reconstruction.
