Abstract

Background: In laparoscopic distal pancreatectomy (LapDP), the pancreas is accessed in a greater curvature approach (GCA). The lesser curvature approach (LCA) has been proposed in underweight patients. The study investigated the feasibility of LCA irrespective of the body mass index (BMI).

Methods: This retrospective study included consecutive patients scheduled to undergo LapDP with the LCA. A matched cohort (1:1) underwent GCA. Spleen preservation was performed using the Warshaw technique. Splenic perfusion was intraoperatively assessed by indocyanine green (ICG) angiography.

Results: The LCA with LapDP was successful in 12/15 patients. In 2 cases, LCA had to be converted to GCA and in 1 patient to open surgery. The cohorts were well matched in sex (P = 1.0), age (P = .67), indication (P = 1.0), and median BMI (23.4 kg/m2 vs 24.8 kg/m2, P = .41). Splenic preservation was achieved in 14/15 patients with LCA and 4/15 patients with GCA (P = .33). In all LCA cases, ICG angiography indicated sufficient spleen perfusion. The groups had similar morbidity (P = 1.0) and hospital stay (P = .74).

Conclusions: LCA was feasible in 80% irrespective of BMI and provided an excellent field of exposure. ICG angiography was feasible in the Warshaw technique. Its reliability should be evaluated in prospective studies.
