Outcome comparison in patients undergoing laparoscopic cholecystectomy using low pressure and standard pressure pneumoperitoneum

Background: laparoscopic cholecystectomy is now an established form of treatment for patients with symptomatic gall stones. although thought to result in less postoperative pain,recent studies have shown that patients may experience considerable pain after laparoscopic cholecystectomy. surgeons used different ways to reduce the intensity of post-operative pain. the low pressure pneumoperitoneum during laparoscopic cholecystectomy proved to be very effective in this aspect. aim: to compare outcome in patients undergoing laparoscopic cholecystectomy using low pressure and standard pressure pneumoperitoneum. methods: 180 patients were selected for study and equally divided in two equal groups. both groups underwent laparoscopic cholecystectomy using standard pressure pneumoperitoneum in group a and low pressure pneumoperitoneum in group b. operative time (min),postoperative pain (vas) and frequency of shoulder tip pain was noted in both groups results: the mean age in splc and lplc groups was 38.71±8.84 years and 40.41±12.50 years respectively. there were 19(21.21%) males in splc and 13(14.44%) in lplc while there were 71(78.89%) females in splc and 77(85.56%) in lplc. the mean operative time in splc and lplc groups was 35.4±8.95 and 37.4±7.89 minutes respectively,the mean operative time in both groups was statistically same,p-value > 0.05. the mean pain on visual analogue scale in splc and lplc groups was 3.46±0.74 and 2.84±0.75 respectively; the mean pain in lplc was statistically less as compare to splc,p-value < 0.05. shoulder tip pain in splc and lplc was observed in 67(74.44%) and 84(93.33%) respectively,p-value < 0.05. conclusion: laparoscopic cholecystectomy using low pressure pneumoperitoneum has significant advantages in terms of less post-operative pain and reduced frequency of shoulder tip pain.
