RESUMO
Background: Cholelithiasis is one of the most common surgical diseases. About 1-15% adult population have gallstones. The present study is done to compare the frequency and intensity of post-operative shoulder tip pain (VAS) score in standard pressure v/s low pressure cholecystectomy.Methods: The Comparative, Randomized and Prospective study is conducted on 100patients’ under-going Laparoscopic Cholecystectomy for Cholelithiasis with 50 patients in each group: Group A- Low pressure pneumoperitoneum at 7 to 10mm Hg, Group B- Standard pressure pneumoperitoneum at 12 to14mm Hg in the Department of General Surgery, Muzaffarnagar Medical College and hospital. Postoperative pain was measured at 6, 12, 24, 48 hours using a Visual Analogue Scale (VAS). Statistical analysis was carried out using the chi square and independent student t tests with the help of SPSS (statistical package for social sciences, version 17.0). A p value < 0.05 was taken as statistically significant. Results: Low insufflation pressure reduced pain frequency as well as pain intensity after laparoscopic cholecystectomy. Analgesic requirement is also less in low pressure.Conclusion: Low pressurepneumoperitoneum is ideal for laparoscopic cholecystectomy for decrease frequency and intensity of postoperative shoulder tip pain.
