Abstract
INTRODUCTION: Laparoscopic resections of the pancreatic head are increasingly performed. Several studies show that they are comparable to open operations in terms of postoperative morbidity. However, since a substantial proportion of pancreatic head resections are necessary for pancreatic adenocarcinoma the oncologic safety and outcome of minimally invasive operations is of interest. In this study we evaluated oncologic outcome and survival after laparoscopically assisted pancreatic head resection for ductal adenocarcinoma. METHODS: Perioperative and oncological outcome of sixty-two laparoscopically assisted pancreatic head resections for pancreatic ductal adenocarcinoma performed between 2010 and 2016 was compared to outcome of 278 open resections between 2001 and 2016 in a retrospective study. Data was continuously collected in a prospectively maintained database. RESULTS: Operation time was significantly longer in the laparoscopic group (477 vs. 428 min. p < 0.001). Tumor size, lymph node yield and lymph node state and need of portal vein resection were comparable. There was a higher rate of free resection margins in the laparoscopic group (87% vs. 71%, p < 0.01). There was no difference in postoperative mortality and morbidity. Patients with laparoscopic resection stayed in hospital significantly shorter (median 14 vs. 16 days, p < 0.003). Postoperative survival after 5 years was not different in both groups. CONCLUSION: Laparoscopically assisted resection of adenocarcinoma of the pancreatic head is equal to open resection concerning oncologic outcome and actuarial survival. However, minimally invasive resection shortened the hospital stay. However, further evaluations with a longer follow up time are needed.
