Laparoscopic parenchyma-sparing pancreatectomy.

In recent years laparoscopic pancreatic procedures have developed rapidly, and reports of laparoscopic resection including laparoscopic distal pancreatectomy and laparoscopic pancreaticoduodenectomy have increased in number. On the other hand, many benign and low-grade malignant pancreatic lesions have recently been detected by the improved diagnostic modalities. Parenchyma-sparing pancreatectomy is a preferred surgical procedure for such benign and low-malignancy pancreatic lesions, because parenchyma-sparing pancreatectomy can avoid the unnecessary resection of the normal pancreatic parenchyma, thereby preserving the endocrine and exocrine functions of the pancreas. Simultaneously, laparoscopic surgery has contributed to minimally invasive approaches for various pancreatic surgical procedures. The combination of laparoscopic surgery and parenchyma-sparing pancreatectomy is an ideal surgical procedure for benign and low-grade malignant pancreatic lesions. For laparoscopic parenchyma-sparing pancreatectomy to become more widely known and its indications clarified, it is necessary to demonstrate the clinical benefits, technical feasibility, and safety of this complex and difficult surgical procedure.
