Introduction:
Intracorporeal pouch jejunojejunostomy (JJ) is a technically challenging procedure during totally laparoscopic gastrectomy (TLG).
Aim:
This study introduced a new method involving the construction of an intracorporeal bi-directional pouch JJ using an endoscopic linear stapler and analyzed the surgical outcomes of this method, including JJ complications.
Material And Methods:
We retrospectively reviewed the medical records of 168 patients who underwent laparoscopic gastrectomy with intracorporeal bi-directional pouch JJ between November 2017 and October 2018 at Asan Medical Center.
Results:
The construction of an intracorporeal bi-directional pouch JJ took an average of 10 min. No postoperative bleeding or anastomotic strictures related to JJ reconstruction occurred after this procedure. No mortality occurred during follow-up.
Conclusions:
Intracorporeal bi-directional pouch JJ using an endoscopic linear stapler is a safe and simple procedure. It is a feasible option to reduce JJ stricture after TLG in patients with gastric cancer.
