Aim
Laparoscopic and endoscopic cooperative surgery for early non-ampullary duodenum tumors (D-LECS) is now noted because of its safety and lower invasiveness. Here, we introduce two distinct approaches (antecolic and retrocolic) according to the tumor location during D-LECS.
Methods
From October 2018 to March 2022, 24 patients (25 lesions) underwent D-LECS. Two (8%), two (8%), 16 (64%), and five (20%) lesions were located in the first portion, in the second portion to Vater’s papilla, around the inferior duodenum flexure, and in the third portion of the duodenum, respectively. The median preoperative tumor diameter was 22.5 mm.
Results
Antecolic and retrocolic approaches were employed in 16 (67%) and 8 (33%) cases, respectively. LECS procedures, such as two-layer suturing after full-thickness dissection and laparoscopic reinforcement by seromuscular suturing after endoscopic submucosal dissection (ESD), were performed in five and 19 cases, respectively. Median operative time and blood loss were 303 min and 5 g, respectively. Intraoperative duodenal perforations occurred in three of 19 cases during ESD; however, they were successfully laparoscopically repaired. Median times until start diet and postoperative hospital stay were 4.5 and 8 days, respectively. Histological examination of the tumors revealed nine adenomas, 12 adenocarcinomas, and four GISTs. Curative resection (R0) was achieved in 21 cases (87.5%). In a comparison of the surgical short outcomes between antecolic and retrocolic approaches, there was no significant difference.
Conclusion
D-LECS can be a safe and minimally invasive treatment option for non-ampullary early duodenal tumors, and two distinct approaches according to the tumor location are feasible.
