Pouch and Roux-en-Y reconstruction after gastrectomy

Area of Science:

• Gastroenterology
• Surgical Oncology
• Surgical Technology

Background:

• Total gastrectomy for gastric carcinoma necessitates complex upper gastrointestinal reconstruction.
• Traditional reconstruction methods can be time-consuming and have limitations based on patient age and tumor location.
• The Roux-en-Y technique with a Hunt-Lawrence-Rodino pouch is a common reconstruction method.

Purpose of the Study:

• To evaluate the efficacy and safety of exclusive surgical stapler use for upper gastrointestinal reconstruction after total gastrectomy.
• To assess the functional outcomes (reservoir function and reflux prevention) of stapler-based reconstruction.
• To compare operative times between stapler-based and manual reconstruction techniques.

Main Methods:

• A prospective study involving twenty patients with gastric carcinoma undergoing total gastrectomy and lymphadenectomy.
• Exclusive use of EEA (25), GIA, and TA (55 or 90) surgical staplers for all reconstruction steps, including duodenal closure, Roux-en-Y anastomosis, pouch construction, esophagojejunostomy, and pouch closure.
• Comparison of operative times with TNM-matched patients who underwent manual reconstruction.

Main Results:

• The stapler-only technique successfully achieved reservoir function and reflux prevention in Roux-en-Y reconstructions.
• A one-hour reduction in operative time was observed compared to manual reconstruction.
• Four patients experienced general complications, and two had clinically relevant suture deficiencies.

Conclusions:

• Exclusive use of EEA, GIA, and TA surgical staplers is a viable and effective method for upper gastrointestinal reconstruction after total gastrectomy.
• This stapler-based approach offers significant intraoperative time savings.
• The technique expands the applicability of total gastrectomy by reducing limitations related to patient age and tumor location.
