Natural orifice specimen extraction surgery in laparoscopic pancreaticoduodenectomy: A single-center case series.

Background: Laparoscopic pancreaticoduodenectomy is an appealing and minimally invasive method for pancreaticoduodenal tumors. However, an abdominal incision is still required to extract the specimen. We used the natural orifice specimen extraction technique in laparoscopic pancreaticoduodenectomy to accomplish specimen retraction in 8 female patients and summarized the clinical results. Materials and Methods: A total of 8 female patients with periampullary carcinoma or duodenal cancer who underwent laparoscopic pancreaticoduodenectomy were enrolled in our study between April 2018 and October 2019. A 4-cm transverse incision was made in the posterior vaginal wall, and the specimen was extracted via the vagina. Age, operative time, intraoperative hemorrhage, pathological data of the tumor, postoperative hospital stay, and postoperative complications were recorded and analyzed. All operations were performed laparoscopically, by the same team of surgeons. Results: The mean age of the patients was 67.5 ± 7.7 years. Mean BMI was 23.7 ± 1.7 kg/m2. The operative time ranged between 312 and 460 min. The intraoperative blood loss ranged from 100 to 600 ml. The average hospital stay of all patients was 9.9 ± 2.2 days; 5 out of 8 patients (62.5%) had postoperative complications, including postoperative pancreatic fistula, delayed gastric emptying, and postpancreatectomy hemorrhage. No patient developed short-term complications due to vaginal extraction of specimens. All patients underwent R0 resection. Conclusion: Transvaginal specimen extraction is a practicable method for laparoscopic pancreaticoduodenectomy. By adhering to correct operation specifications and selecting patients with appropriate indications for natural orifice specimen extraction, this technique was safe and beneficial to selected female patients with pancreaticoduodenal tumors.
