title: [Postoperative pain in laparoscopic surgery].
abstract: The occurrence of post-operative pain, although less severe and frequent than in open surgery, may affect length of hospital stay and early return to normal activity in some patients operated on with laparoscopic surgery. Although several pathogenetic factors have been indicated in the literature, the mechanism responsible for post-operative pain after laparoscopy; still remains unclear. In this study the Authors evaluated post-operative pain in 90 patients submitted to laparoscopic cholecystectomy and correlated it to the length of operation, endoabdominal CO2 pressure maintained during surgery, and use of local anesthesia instilled din the liver bed and in the sites of introduction of trocars. Measuring post-operative pain by means of a modified Scott-Huskisson Visual Analogue Scale, no difference in the severity of the pain was noted in the two subgroups of patients with a length of operation inferior or superior to 60 minutes, respectively. Conversely, a statistical significant difference (p = 0.04 and p = 0.049 according to Fisher exact test and Pearson test, respectively) was observed evaluating the use of local anesthesia and the level of CO2 endoabdominal pressure, with less pain in patients whose pressure was maintained under 10 mmHg and in patients treated with instillation of local anesthetic drugs in the liver bed and in the sites of introduction of trocars.
