Surgical treatment of pancreatic insulinomas in the era of laparoscopy

Background: Laparoscopic resection has been increasingly reported for pancreatic insulinomas. This report evaluates our experience with surgical treatment for pancreatic insulinomas in this era of laparoscopy and reviews the application, safety, and outcome of this surgical approach reported in the literature. Methods: In a consecutive series of 10 patients with pancreatic insulinomas, laparoscopic resection was performed for selected patients after routine preoperative localizations. The outcome of this operative strategy was reviewed together with reported cases involving laparoscopic resection of pancreatic insulinomas. Results: Laparoscopic distal pancreatectomy or enucleation was performed for four patients with tumors located at the body or tail of the pancreas, whereas open enucleation was performed for six patients with tumors located at the pancreatic head. Pancreatic leak developed in one laparoscopic and two open enucleations. A review of reported cases in the literature showed that 61 of 69 attempted laparoscopic pancreatic resections for insulinomas were performed successfully. All except two tumors were located at the body or tail of the pancreas. For 42 cases with detailed information, 41 tumors at the pancreas body or tail were removed successfully by enucleation (n = 24) or distal pancreatic resection (n = 17), and one tumor at the pancreatic head was enucleated successfully. Pancreatic fistula, the most frequent complication, occurred in 8 (19%) of 42 laparoscopic resections. Conclusions: Laparoscopic resection of pancreatic insulinomas is safe and feasible for tumors located at the body or tail of the pancreas. Its application for tumors located at the pancreatic head needs further evaluation.     

Laparoscopic Treatment of Benign Insulinomas Localized in the Body and Tail of the Pancreas: A Single-center Experience

Background The increasingly widespread use of minimally invasive surgery has allowed surgeons to exploit this approach for complex procedures, such as pancreatic resections, though its actual role outside simple operations remains debated. Methods This is a study of 12 consecutive patients, 5 men and 7 women, with pancreatic insulinoma who were treated at our institution from 2000 to September 2005. All patients presented with typical symptoms and laboratory findings of hyperinsulinism and were good candidates for laparoscopic surgery. Preoperative diagnostic work-up, operating time, postoperative complication rate, length of hospital stayd and clinical outcome were assessed. Results Successful laparoscopic resection was performed in 11 out of 12 patients: 4 had tumor enucleation, and 7 had distal pancreatectomy; among these latter 5 had spleen-preserving distal pancreatectomy. In 1 case conversion to open surgery was necessary. Mean operative time was 170 minutes. The median tumor size was 18 mm, and all the insulinomas were benign. Four complications were observed in this group, and the median hospital stay was 8 days. Conclusions The laparoscopic approach proved to be feasible and safe, although the average operative time was longer and demanded good surgical skills as well as precise localization of the tumor and definition of its nature. Tumors located in the body or tail of the pancreas that are benign in nature can better benefit of laparoscopic approach.

Laparoscopic ultrasonography for resection of insulinomas.

BACKGROUND: There have been few reports on the use of laparoscopic ultrasonography as an aid for the resection of insulinomas. In this study, we review our experience with laparoscopic ultrasonography for the intraoperative localization and resection of insulinomas. METHODS: We attempted laparoscopic resection of insulinomas in 7 patients (median age, 50 years) during a 4-year period. Preoperative imaging showed that 1 of the insulinomas was located in the head of the pancreas, 2 were located in the body, and 4 were located in the tail. RESULTS: We identified the insulinomas in all 7 patients with laparoscopic ultrasonography. In 6 of the patients, the insulinomas were laparoscopically resectable, either by enucleation (4 patients) or by resection of the pancreatic tail (2 patients). Conversion to laparotomy was necessary for the insulinomas in the head of the pancreas because they were close to the portal vein and the major pancreatic duct. All patients showed improvement in their hypoglycemia after the operations. Minor leakage of pancreatic juice occurred in 4 patients, and this was resolved with conservative treatment. CONCLUSIONS: Laparoscopic ultrasonography is useful for the intraoperative localization of insulinomas. Laparoscopy is a safe and feasible technique for resecting insulinomas located in the body or tail of the pancreas.

Laparoscopic detection and resection of insulinomas

BACKGROUND: Laparoscopic ultrasonography as a diagnostic tool for the localization of islet cell tumors has been described before, but few reports on laparoscopic resection of insulinomas exist. We retrospectively reviewed the results of our experience with laparoscopic detection and the resection of insulinomas to determine its feasibility. METHODS: Between February 1996 and February 1999, 10 patients underwent operation for organic hyperinsulinism at our institution. Patient and clinical characteristics were studied retrospectively. Laparoscopic ultrasonography was performed to localize the insulinoma and then laparoscopic resection was performed. RESULTS: Eight women and 2 men underwent operation for hyperinsulinism. In 6 patients the insulinoma could be resected laparoscopically, either by enucleation (5 patients) or by resection of the pancreatic tail (1 patient). Four procedures were converted to laparotomy for the proximate location of the insulinoma to the portal vein or pancreatic duct (3 procedures) and failure to identify the insulinoma (1 procedure). The overall success rate of preoperative localization of an insulinoma with the use of various imaging techniques was 60% (6/10 patients). Laparoscopic ultrasonography could identify an insulinoma in 90% of the patients (9/10 patients). The median hospital stay was 7 days. CONCLUSIONS: Laparoscopic ultrasonography followed by laparoscopic removal of the insulinoma in patients with clinically manifested hyperinsulinism is a feasible and safe technique with low morbidity and fast postoperative recovery. Preoperative localization studies appear of limited value.
