Background: The validity of laparoscopic distal pancreatectomy in left-sided pancreatic adenocarcinoma (PDAC) is still unclear. However, a meticulous surgical dissection through a “no-touch” technique might allow a radical oncological resection with minimal risk of tumor dissemination and seeding. This study aims to evaluate the oncological outcomes of the laparoscopic “no touch” technique versus the “touch” technique Methods: From 2001 to 2020, we analyzed retrospectively 45 patients undergoing LDP (laparoscopic distal pancreatectomy) for PDAC from two centers. Factors associated with overall (OS), disease-free (DFS) survival and Time to recurrence (TTR) were identified. Results. The OS rates in the ‘no-touch’ and ‘touch’ groups were 95% vs 78% (1-year OS); 50% vs 50% (3-year OS), respectively (p=0.60). The DFS rates in the ‘no-touch’ and ‘touch’ groups were 72 % vs 57 % (1-year DFS); 32% vs 28 % (3-year DFS), respectively (p=0.11). The TTR rates in the ‘no-touch’ and ‘touch’ groups were 77 % vs 61 % (1-year TTR); 54% vs 30 % (3-year TTR); 46% vs 11 % (5-year TTR); respectively (p=0.02) In multivariate analysis the only factors were Touch technique (OR= 2.62, p= 0.02) and lymphovascular emboli (OR= 4.8; p=0.002). Conclusion. We advise the ‘no-touch’ technique in patients with resectable PDAC in the pancreatic body and tail. Although this study does not provide definitive proof of superiority, no apparent downsides are present for the ‘no-touch’ technique in this setting although there could be oncological benefits. |
