Neuroendocrine tumours of the pancreas are rare but can be fatal due to excessive secretion of regulatory peptides. The localization of these small tumours can be difficult while open surgical treatment is associated with a relatively high morbidity. Two cases are presented where endocrine tumours of the pancreas were successfully removed by laparoscopy. In the surgical treatment of endocrine pancreatic tumours, the use of laparoscopic techniques can provide a valuable means for localizing the tumour while improving the patient's comfort and decreasing operative morbidity.

The use of laparoscopic surgery in peritonitis has increased rapidly. The present study examined the effects of pneumoperitoneum on bacterial clearance. Spraque-Dawley rats were divided into six groups of seven animals. ⋯ The quantitative bacteria was significantly higher in the E. coli injection with laparotomy group than in the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.05). This study demonstrates that pneumoperitoneum impairs the clearance of bacteria from the peritoneal cavity in an experimental model of peritonitis. However, we could not detect the deleterious effects of pneumoperitoneum compared with laparotomy.
