To determine the safety and effectiveness of gastroenterostomy performed using minimally invasive techniques.

Retrospective analysis of treatment results of all patients with symptoms of high gastrointestinal obstruction who underwent laparoscopic or endoscopic (EUS-guided) gastrointestinal anastomosis in the years 2020–2025 at the Department of General, Gastroenterological and Oncological Surgery, Collegium Medicum Nicolaus Copernicus University in Toruń, Poland.

In 64 patients (51 men, 13 women; mean age 61.72 [39-91] years) with symptoms of high gastrointestinal obstruction, gastrointestinal anastomosis using minimally invasive techniques was performed. Laparoscopic surgery was performed in 34/64 (53.13%) patients, and endoscopic surgery in the remaining 30/64 (46.87%) patients. Gastrointestinal malignancy was the cause of obstruction in 57/64 (89.06%) patients. Technical success was achieved in 59/64 (92.19%) patients. Complications of surgical treatment were observed in 14/64 (21.88%) patients. Clinical success of gastrointestinal anastomosis using minimally invasive techniques was achieved in 55/64 (85.94%) patients. During a mean follow-up period of 412 (155-1211) days, 2/64 (3.13%) patients required endoscopic re-intervention due to gastrointestinal anastomosis stricture.

Gastroenterostomy using minimally invasive techniques is a safe and effective treatment method for patients with high gastrointestinal obstruction
