Clamp-crushing Pancreatic Transection in Minimally Invasive Distal Pancreatectomy.

Abstract

Minimally invasive distal pancreatectomy has become a widely accepted procedure for tumors located in the pancreatic body or tail. However, pancreatic transection by linear stapler is generally avoided for pancreatic body tumors located above the portal vein because the surgical margin width is narrowed after taking into account the cutting allowance for insertion of the stapling device. Herein, we report a parenchymal clamp-crushing procedure that provides a sufficient surgical margin in pancreatic transection. Two patients with suspected early pancreatic cancer underwent pancreatic transection using the clamp-crushing procedure. The planned pancreatic transection line was set just to the left of the gastroduodenal artery in both cases. Robotic and laparoscopic distal pancreatectomy were performed in 1 patient each. Patients were positioned supine with split legs. Parenchymal transection was performed with crushing by VIO 3 (ERBE Elektromedizin) operated in softCOAG Bipolar mode with Effect 2/modulation 50. After crushing, remnant tissue was cut in autoCUT Bipolar mode operated by VIO 3 with Effect 2/modulation 50, or cut after secured by clipping. The surgical duration was 253 and 212 minutes, and estimated blood loss was 0 and 50mL in the 2 patients, and both were discharged with uneventful courses. Pathologic examination confirmed a negative surgical margin in both patients. Clamp-crushing pancreatic transection for distal pancreatectomy might be a suitable treatment option for achieving sufficient surgical margin in pancreatic body tumors located close to the portal vein.
