Laparoscopic treatment of pancreatic insulinoma

Laparoscopy and laparoscopic ultrasonography (LUS) have been proposed for the diagnosis and treatment of pancreatic insulinoma. We present for cases of pancreatic insulinoma approached by laparoscopy guided by LUS. In three cases, insulinomas were in the pancreatic body and in one case in the pancreatic head. All lesions were detected preoperatively by abdominal US and confirmed by computed tomography. Laparoscopy was performed under general anesthesia. LUS was performed using a 10-mm flexible probe. In two cases the adenoma was enucleated using scissors and electrocoagulation, major vessels were controlled using clips, and enucleation was completed using a 30-mm endo-GIA. In one case a laparoscopic distal pancreatectomy with spleen preservation was performed. In one case the adenoma was deep in the pancreatic head; minilaparotomy was performed and the adenoma enucleated. Patients were discharged in good health 5–7 days after surgery. The postoperative course was complicated in one case of enucleation by peripancreatic fluid collection that was treated percutaneously. Our experience confirms that accurate localization followed by excision of tumors via the laparoscopic approach constitute a significant advance in the management of insulinoma.

Laparoscopic left hemicolectomy in a patient with cirrhosis scheduled for liver transplantation

Hepatic cirrhosis is a negative prognostic factor for major abdominal surgery, with a greater risk of bleeding, infection, and ascites. The case of a 54-year-man with adenocarcinoma of the sigma affected by hepatitis B virus and hepatitis C virus hepatopathy as well as micro- and macrconodular cirrhosis (Child’s B7 stage) waiting for liver transplantation is reported. After a consultation with the liver transplantation our hospital, and considering the the patient’s age laparoscopy was determined to be the procedure of choice because it would give him the possibility of a transplantation in the future. A typical left hemicolectomy with left flexure mobilization and mechanic colorectal T-T-anastomosis was therefore performed. All surgical maneuvers in the right hypochondrium were avoided. Mobilization was performed using an ultrasonic scalpel to reduce the risk of bleeding, and the anatomic stump was pulled out by means of a midline minilaparotomy, sparing the anastomotic circles of the abdominal wall. Follow-up evaluation was uneventful. At an 8-month follow-up visit, the patient was in good general condition. In this case, laparoscopic surgery allowed an oncologically suitable colonic resection without complication and poor surgical stress. Moreover, open surgery would have reduced the possibility of a transplantation in the future.
