Current Management of Laparoscopic and Endoscopic Cooperative Surgery for Duodenal Neoplasia: Suitable Endoscopic Resection Approaches.

Introduction: Duodenal laparoscopic and endoscopic cooperative surgery (D-LECS) is a promising hybrid approach to managing duodenal neoplasia, including superficial non-ampullary duodenal epithelial tumors (SNADETs) and subepithelial lesions (SELs). This approach aims to reduce adverse events (AEs), such as delayed perforation, often associated with endoscopic submucosal dissection (ESD). Combining laparoscopic techniques for duodenal stabilization with precise endoscopic resection, D-LECS may provide safer and more comprehensive treatment. However, few studies have compared the outcomes of D-LECS with those of ESD and full-thickness resection (FTR), and suitable endoscopic resection approaches for D-LECS remain unclear.

Methods: We retrospectively reviewed records of 80 patients who underwent D-LECS for duodenal neoplasia at our institution between 2011 and 2024. Fifty-six patients underwent D-LECS with ESD for SNADETs (ESD group), whereas 24 underwent D-LECS with FTR for 16 SELs and 8 SNADETs (FTR group). All patients underwent en bloc resection, showing an overall R0 resection rate of 92.5%.

Results: There was no significant difference in overall incidence of Clavien-Dindo grade II or higher AEs between the ESD and FTR groups. However, the ESD group tended to have fewer cases of delayed gastric emptying and higher inflammatory response (p = 0.087 and p = 0.063, respectively). One patient in the FTR group experienced delayed perforation and 2 patients in the ESD group experienced delayed bleeding. However, these events were not significant.

Conclusions: Both D-LECS with ESD and FTR were effective and safe. D-LECS with ESD may be a more suitable approach for SNADETs, whereas D-LECS with FTR is preferable for SELs.
