Introduction: In locally-treatable gastrointestinal tumors, laparoscopic endoscopic cooperative surgery (LECS) is a minimally-invasive technique that can avoid excessive resection of the gastrointestinal tract.
Objective: To share our therapeutic guidelines and surgical technique of LECS for gastroduodenal tumors.
Subjects: Nineteen patients who underwent LECS for gastroduodenal tumors (10 patients with gastric tumor and 9 patients with duodenal tumor). [Results]1)Gastric tumors (9 GIST, 1 glomus):1.Site of lesion was U (4 patients), M (3), or L (2), 2.Operative procedure was acquired in a stepwise manner from classical LECS (4 patients) to inverted LECS (2) to non-exposed endoscopic wall-inversion surgery: NEWS(4). 3.Operative outcome revealed no postoperative complications. 2) Duodenal tumors (6 adenoma, 2 M cancer, 1 ectopic pancreas):1.Site of lesion was bulbus duodeni (1 patient), superior part (2), or descending part (6); 2.Operative procedure was ESD followed by laparoscopic continuous suture in a single seromuscular layer for patients with preoperatively confirmed or suspected cancer, or full-thickness resection followed by Albert-Lembert suture along the short axis for patients unable to undergo ESD. In all cases, C-tube was placed to prevent bleeding and perforation at the site of resection due to exposure to bile; 3.Operative outcome included successful endoscopic hemostasis upon bleeding from exposed vessel on postoperative day 4 in 1 patient and anastomotic leak in 1 patient. The event of anastomotic leak resolved after 14 days of bile drainage through C-tube and conservative therapy. Compared with 26 patients who underwent ESD alone, those who underwent LECS had significantly larger diameters of resected specimens and tumors (p < 0.05) but no significant difference in the incidence of postoperative bleeding and delayed perforation.
Conclusion: For gastroduodenal tumors, LECS is a minimally-invasive and safe therapeutic option as it combines advantages of both laparoscopy and endoscopy. In particular, C-tube placement for bile drainage was effective in reducing exposure of the suture site to bile as well as supporting drainage after anastomotic leak.
