title: [Videolaparoscopic excision of insulinoma. A study of 5 cases].
abstract: OBJECTIVE
  Evaluation of the feasibility of the videolaparoscopic resection in pancreatic insulinomas, and reporting of five cases.
  
  
  METHODS
  From 1996 to 1998, a videolaparoscopic resection was attempted in five patients with sporadic, unique and benign insulinoma. The insulinoma was recognised and localised by preoperative ultrasonography in the pancreatic head (n = 1), body (n = 3) or tail (n = 1). For the videolaparoscopic procedure, three to five trocars were necessary. Cephalic and corporeal insulinomas were approached through an opening of the gastrocolic ligament and caudal insulinoma required mobilisation of the splenic flexure of the colon and dissection of the splenic pedicle. Peroperative ultrasonography was not used.
  
  
  RESULTS
  Four resections were exclusively performed with videolaparoscopy: three enucelations and one distal pancreatectomy with splenic preservation. The cephalic insulinoma could not be found by laparoscopic exploration and required a laparotomy to be recognised and enucleated; it was located further down than expected. There were no postoperative complications in four patients. One enucleation was complicated by a pancreatic fistula that required reoperation. All the patients were cured with a 6- to 16-month follow-up.
  
  
  CONCLUSIONS
  Selected insulinomas may be operated on with videolaparoscopy. Preoperative endoscopic ultrasonography is necessary for this selection. Videolaparoscopic approach is contraindicated in multiple insulinomas, in insulinomas located on the posterior wall or deeply located in the head of the pancreas, and in malignant tumors. Videolaparoscopic resection is mainly indicated in unique and benign insulinomas, superficially located on the anterior wall of the pancreas, to be resected by enucleation or distal pancreatectomy. Disadvantage of laparoscopic approach compared to conventional approach is the absence of palpation and difficulty to explore the whole pancreas; advantage is the lack of parietal incision and the good postoperative comfort.
