BACKGROUND: Uncinate process dissection is a key step in minimally invasive pancreaticoduodenectomy (MIPD), including laparoscopic and robotic procedures, which increase the intraoperative blood loss and operative time and decrease the R0 resection rate if improperly handled. However, few studies have reported the operative skills in detail.
METHODS: We performed uncinate process dissection using a combination of the anterior superior mesenteric vein (SMV)-first approach and the right posterior superior mesenteric artery (SMA)-first approach in MIPD for 138 patients with periampullary tumors between March 2017 and October 2019. The demographic and perioperative data of all the patients were collected to evaluate the efficacy of this method.
RESULTS: All patients underwent an uneventful operation. An assistant incision was performed to separate extensive adhesion between the tumor and the SMV in 3 patients. The combined approach had a notably shorter operation time and resection time, less intraoperative blood loss and a shorter postoperative hospital stay than the traditional approach (P<0.05). There were no significant differences in conversion rate, numbers of harvested lymph node or postoperative complications, including postoperative pancreatic fistula, bile leakage, delayed gastric emptying, postoperative bleeding and reoperation between the two groups (P>0.05). There were no deaths during the perioperative period.
CONCLUSIONS: The combination of the anterior SMV-first approach and the right posterior SMA-first approach is a safe and feasible technique for uncinate process dissection in MIPD.
