Laparoscopic procedures have advanced to represent the new gold standard in many surgical fields. Although application in pancreatic surgery is hampered by the friable nature of the gland and the difficulty of its exposure, advanced technology and surgeons' experience are leading to an expansion of minimally invasive pancreatic surgery. Addressing the whole range of main operative procedures, this review analyzes the literature data so far to give an overview about the current status of minimally invasive pancreatic surgery, its indications and limitations. In acute pancreatitis, a step-up approach from percutaneous drainage to retroperitoneoscopic necrosectomy seems beneficial. Transgastric necrosectomy also preserves the retroperitoneal compartment in contrast to the laparoscopic approach, which has widely been abandoned. In tumor pathology, laparoscopic access is adequate for small benign lesions in the pancreatic tail and body. Oncological outcome shows to be at least equal to the open procedure. Concerning laparoscopic pancreaticoduodenectomy, there is no evidence for a patients' benefit currently although several studies prove that it can be done.
Standardization of the surgical technique, "bloodless" surgery, standardization of intraoperative monitoring, and the use of board-certified anesthesiologists for high-risk cases, emergency procedures, and patients with high ASA stages are able to reduce postoperative morbidity.
Based on our prospective data (grade of evidence II), we consider laparoscopic sigmoid resection with primary anastomosis (in continuity) in Hinchey stages I and II without prior interventional drainage and colon preparation to be justified.
Factors such as overweight, ASA classification or urgency cannot be changed. Surgical factors such as a standardisation of the operation technique with reduction of the operating time and careful staunching of bleeding can help to reduce postoperative complications. Anesthesiologists can also help by avoiding a change of the anesthesiologist as well as by preference of specialists in patients with higher ASA stages and in emergency cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
