Laparoscopic distal pancreatectomy with preservation of the spleen.

We describe a case of chronic pancreatitis treated by laparoscopic distal pancreatectomy with conservation of the spleen involving the resection of the splenic vessels. A proximal ligation of the splenic artery and vein was performed, followed by transection of the body of the pancreas. Retroperitoneum was dissected to the left by mobilizing the stump of the transected pancreas. The entire distal pancreas was freed posteriorly. The distal splenic artery and vein were ligated and divided individually adjacent to the tail of the pancreas at the hilum of the spleen. The points of this operation were to ligate the splenic artery and vein at both sides of the resected pancreas and to save the spleen with the blood supply continuing through the short gastric vessels and the splenocolic ligament. This operation with splenic preservation is more suitable for a patient who is a candidate for laparoscopic distal pancreatectomy, which will minimize the operation time, preserve the useful immunologic role of the spleen, and obtain the intact resected specimen. Furthermore, this procedure is useful in chronic pancreatitis patients because it avoids the difficult dissection of the posterior pancreas off of the splenic vessels.
