Laparoscopic versus open pancreaticoduodenectomy: Long-term outcome from a tertiary care centre

Abstract

Abstract Introduction: Laparoscopic Whipple’s pancreaticoduodenectomy (WPD) is one of the most advanced minimally invasive procedures. In recent years, with advancements in minimally invasive surgery, laparoscopic WPD has been increasingly adopted as a safe and feasible technique. This study aims to compare the short-term and long-term outcomes of laparoscopic WPD to open WPD in resectable ampullary, periampullary and head of pancreas malignancies. Patients and Methods: A retrospective analysis of a prospectively maintained database of patients who underwent WPD from January 2015 to January 2021 at the department of surgical gastroenterology in a tertiary care medical college hospital was conducted. Patient demographics and pre-operative details, intraoperative parameters (operating time and blood loss), post-operative length of hospital stay, median intensive care unit (ICU) stay, time to resume oral diet, post-operative complications, interventional procedures, mortality, 3-year survival, 3 year recurrence-free survival and overall survival were analysed. Results: Forty-two patients underwent WPD during our study period; 14 patients underwent laparoscopic WPD and 28 patients underwent open WPD. None required conversion. The majority of the patients had periampullary carcinoma in both the groups. Laparoscopic WPD showed a trend towards shorter ICU stays, hospital stays and surgical site infections (SSIs) compared to open WPD. The median operating time was significantly longer in the laparoscopic WPD group (380 min) compared to the open group (285 min). However, median blood loss was significantly lower in the laparoscopic group (250 mL vs. 300 mL). The pancreas-specific post-operative complications like delayed gastric emptying, post-operative pancreatic fistula or post-operative pancreatic haemorrhage did not differ significantly between the groups. All patients had R0 resection and the mean lymph node yield was comparable between the two groups (14.92 vs. 13.42). The reoperation rate or mortality rate did not show any statistical significance between the two groups. The overall survival was 46 months in the open group and 48 months in the laparoscopic group. Three-year survival was 74.1% in the open WPD group and 69.2% in the laparoscopic group. Three-year recurrence-free survival was 55.5% in the open group and 69.23% in the laparoscopic group. Conclusion: Laparoscopic WPD appears to be safe and feasible, with similar short-term and long-term survival outcomes. With a trend favouring laparoscopic WPD in terms of blood loss, hospital and ICU stay and post-operative SSIs, it should be offered to selected patients when the expertise is available.
