WITHDRAWN: Research and application of laparoscopic precision pancreatic cancer surgery based on three-dimensional reconstruction

Abstract

Abstract Objective To evaluate the clinical value of image studies using three-dimensional reconstruction techniques in preparation for laparoscopic pancreatic tumor resections. Methods We retrospectively collected the clinical data of patients with pancreatic tumors from January 2017 to November 2018. A total of 204 patients were randomly divided into a study group or control group. The patients in study group performed preoperative three-dimensional reconstruction and patients in control group did not. The operation time, intraoperative blood loss, number of lymph nodes retrieved, and R0 resection rate were recorded. Results In patients undergoing laparoscopic pancreaticoduodenectomy, patients in study group had higher R0 resection rate (96.72% vs. 83.93%, p = 0.031), larger number of dissected lymph nodes (10.71 ± 7.20 vs. 4.98 ± 2.56, p = 0.010), shorter operation time (273.4 ± 91.3 min vs. 371.7 ± 102.4 min, p Conclusion Preoperative three-dimensional reconstruction is helpful for tumor localization in laparoscopic pancreatic tumor resection. This preoperative method can shorten the operation time, reduce intraoperative bleeding, and improve the cure rate of pancreatic tumors during laparoscopic pancreaticoduodenectomy.
