Three thousand, five hundred and seventy-two laparoscopic procedures were analysed retrospectively from a single institution between 1996 and 2003. Operations were classified into four groups as diagnostic laparoscopy (386, 10.8%), minor (1092, 30.5%), major (1866, 52.4%) and advanced (228, 6.5%) laparoscopic procedures. Overall, 67 (1.88%) complications occurred. The complication rates were 1.81%, 1.37%, 1.82% and 4.82% in the respective groups. One death (0.03%) occurred due to aortic injury during insertion of the principal intraumbilical trocar. Complications during insertion of the Verres needle, principal and accessory trocars were noted in 25 cases (38.2%) and were comparable among the four groups. Intraoperative complications occurred in 32 patients (47.8%) encountered mainly in the major and advanced groups. Overall, acute postoperative complications occurred in 10 (14.9%) patients. Despite advanced technology and experience, complications during the installation phase of laparoscopy remain a major cause of significant morbidity and most operative complications occurred in advanced operative procedures. Complications associated with all types of laparoscopic procedures should not be underestimated.

Tenoxicam 20 mg i.v. was found to be ineffective whereas bupivacaine was superior to other groups in reducing pain and analgesic requirements. Bupivacaine also increased time to first analgesics and obtained better recovery characteristics, underlining its value in prophylactic pain management compared to the other two agents.
