Despite single-incision laparoscopic surgery (SILS) being a standard procedure, its main shortcomings include narrow operating space and instrument collisions. Although the proposal of single-incision plus one-port laparoscopic surgery (SILS + 1) reduces the operational difficulty, laparoscopic pancreaticoduodenectomy (LPD) involves complex digestive tract resection and anastomosis. To reduce the number of incisions while ensuring the quality of LPD, we propose a single-incision plus two ports LPD (SILPD + 2) procedure wherein a surgeon uses two trocars with a traditional layout while the assistant and scope assistant conduct subumbilical incision. Retrospective analysis was performed of the perioperative data of 64 patients who underwent total LPD at our department from January to June 2023, including their age, gender, surgical operation time, estimated bleeding loss, and postoperative complications. Based on the number of inserted trocars, the patients were assigned to the conventional LPD (CLPD) group (n = 55) with five incisions and the new SILPD + 2 group (n = 9). A total of 64 patients were included in this study, including 55 in the CLPD group and 9 in the SILPD + 2 group. The SILPD + 2 group patients had lower age and body mass index when compared to the CLPD group patients, albeit there was no statistical significance. In both groups of patients, laparoscopic surgery was completed. Regarding the operation time, estimated blood loss, and intraoperative blood transfusion, the SILPD + 2 group showed no significant disadvantage. When compared to CLPD, SILPD + 2 reduced the surgical difficulty by reducing incisions, and there was no significant difference in the short-term prognosis outcomes.
