Background: s/Aims: Postoperative pancreatic fistula (POPF) remains a significant complication following pancreatoduodenectomy (PD). It has been hypothesized that single loop (SL) reconstruction may increase the risk of POPF, leading to the proposal of double-loop (DL) reconstruction. In this approach, the pancreatic duct is connected to an isolated loop of bowel in a Roux-en-Y configuration. Methods: We conducted a retrospective multicenter study to compare various types of reconstruction after PD, analyzing data from 1,502 patients who underwent open, laparoscopic, or robotic PD across 28 centers worldwide. Propensity score matching (PSM) was applied to enhance comparability. Results: The overall rate of POPF was 34.89%, with a grade C POPF rate of 4.26%. The type of reconstruction (SL vs. DL) did not significantly impact the rates of POPF or grade C POPF, both before and after PSM. The rate of delayed gastric emptying (DGE) was 20.71%, and patients with DL reconstruction had a lower incidence of DGE both before and after PSM. Conclusions Our study found no significant differences in the risk of POPF between SL and DL reconstruction. However, DL reconstruction is associated with a reduced risk of DGE, suggesting it may be a preferable option following open PD.

Purpose: Laparoscopic complete mesocolic excision (CME) right colectomy is a technically demanding procedure infrequently employed in Western centers. This retrospective cohort study aims to analyze the safety of laparoscopic CME colectomy compared to standard colectomy for right-sided colon cancer in a Western series. Methods: Prospectively collected data from 60 patients who underwent laparoscopic CME right colectomy were compared to the ones of 55 patients who underwent laparoscopic standard right colectomy. Results: No differences in clinical characteristics were observed between the CME and standard right colectomy groups. No differences were demonstrated in terms of blood loss (P = 0.060), intraoperative complications (P = 1), conversion rate (P = 0.102), and operative time (P = 0.473). No deaths were observed in either group, while complication rate was 40.0% in the CME and 49.1% in the standard group (P = 0.353). Severe complications occurred in 10.0% vs. 9.1% (P = 0.842), redo surgery in 5.0% vs. 7.3% (P = 0.708), and unplanned readmission in 5.0% vs. 5.5% (P = 1) after CME and standard colectomy, respectively. A significant difference in favor of CME was observed in the total length of specimen (P < 0.001), proximal (P = 0.018), and distal margins (P = 0.037). The number of lymph nodes harvested was significantly higher in the CME group (27 vs. 22, P = 0.037). Conclusion In Western series, where patients have less favorable clinical characteristics, laparoscopic CME allows to obtain better quality surgical specimens and comparable short-term outcomes compared to standard right colectomy.
