Impact of different operative approaches for laparoscopic pancreaticoduodenectomy on short-term treatment outcomes / 中华肝胆外科杂志

ABSTRACT

Objective:To study the impact of traditional versus artery first approach in laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 58 patients who underwent laparoscopic pancreaticoduodenectomy using the two different approaches from February 2016 to August 2018 at the Xianyang Central Hospital affiliated to Xi'an Jiaotong University Medical Department were retrospectively analyzed.Results:All 58 patients successfully underwent the complete laparoscopic Whipple operation using the Child digestive tract reconstruction and anastomosis. There was no conversion to laparotomy. The average operation times for the conventional approach group (35 cases) was (302.0±20.0) min and the digestive tract reconstruction time was (36.0±15.0) min. The intraoperative blood loss was (365.0±150.0) ml. Negative pathological resection margins on intraoperative frozen section examination were achieved in 33 patients. Early postoperative complications happened in 6 patients which included grade A pancreatic fistula in 3 patients (1 patient complicated with biliary fistula and 1 patient complicated with gastric emptying disorder), and grade B pancreatic fistula in 2 patients who were complicated with abdominal hemorrhage, successfully treated by conservative treatment. Postoperative pathological examination showed that 32 patients (91.4%) had R 0 resection and 3 patients (8.6%) had R 1 resection. The number of lymph node dissection was (7.5±5.5). On the other hand, the average operation time of the artery first access group (23 cases) was (355.0±25.0) min, and the reconstruction time of digestive tract was (41.0±12.0) min. The amount of bleeding was (410.0±200.0) ml. During the operation, 22 patients had negative resection margins shown on pathological frozen sections. Early postoperative complications occurred in 3 patients, including 1 patient with grade A pancreatic fistula which was complicated with gastric emptying disorder, and 2 patients with grade B pancreatic fistulas which were complicated with abdominal hemorrhage. The patients were successfully managed by conservative treatment. Postoperative pathological examination showed that 22 patients (95.7%) had R 0 resection and 1 patient (4.3%) R 1 resection. The number of lymph node dissection was (6.8±4.2). Conclusion:The LPD surgical approach was selected according to the general conditions of patients, locations of tumors, relationship of tumors with blood vessels, and technical skills of surgeons with the aims to achieve adequate lesion clearance, organ protection, damage control, and safety and efficiency of minimally invasive surgery.
