Preliminary experience with a new robotic technique to facilitate distal pancreatectomy with spleen preservation: left lateral approach in right lateral decubitus position

Spleen-preserving distal pancreatectomy (SP-DP), for patients with benign or small low-grade malignant tumors of the body or tail of the pancreas, is the ideal procedure although it is technically demanding. The robotic da Vinci system has been introduced to overcome these technical challenges and reduce operative risks. We report our experience of a new variation in surgical technique: the left lateral approach robotic spleen-preserving distal pancreatectomy (RSP-DP) in right lateral decubitus position. We performed this new variant of SP-DP, in five patients, using the da Vinci Xi system. Technical and clinical feasibility are described. The mean age and body mass index were 53.4 years and 31.4 kg/m 2 , respectively. The mean total operative time was 323 min. The estimated mean blood loss was 240 ml. In all patients, the spleen could be preserved. In four patients, the splenic vessels were also preserved. One patient required a Warshaw technique due to significant fibrosis attached to the splenic vein. The postoperative period of all patients was uneventful except the presence of biochemical leak (BL) in two patients that only required maintenance of the drainage at home. The mean length of hospital stay was 6 days after surgery. The left lateral approach robotic SP-DP in right lateral decubitus position is a feasible and safe procedure for distal benign or small low-grade malignant tumors of the left pancreas. The right lateral decubitus position associated to robotic surgery can facilitate this complex procedure, especially when splenic vessels preservation is indicated, with a lower risk of conversion and shortening of the learning curve.
