[Invaginated esophageal anastomosis]

Area of Science:

• Gastroenterology
• Surgical Oncology
• Surgical Innovation

Context:

• Gastric cancer surgery frequently requires total or subtotal stomach removal (extirpation).
• Post-gastrectomy reconstruction presents challenges, including anastomosis integrity and functional recovery.
• Invaginated esophageal-intestinal anastomosis is a specific surgical technique for reconstruction.

Purpose:

• To present the surgical technique of invaginated esophageal-intestinal anastomosis.
• To demonstrate the advantages of this technique in gastric cancer surgery.
• To evaluate the outcomes and complication rates associated with this method.

Summary:

• A total of 562 gastric cancer surgeries utilized an invaginated esophageal-intestinal anastomosis.
• The technique's main benefits include improved postoperative physiological function and reduced suture insufficiency.
• Complication rates after extirpation and proximal resection were 17.6%, with a 5.9% mortality rate. Anastomotic suture insufficiency occurred in 14% of cases, leading to 0.7% mortality.

Impact:

• The invaginated anastomosis technique offers a potentially safer and more functional reconstruction method after gastric cancer surgery.
• Reduced rates of anastomotic complications can lead to better patient outcomes and lower morbidity.
• This surgical approach may become a valuable option for gastric cancer surgeons aiming to optimize patient recovery.
