    ABSTRACT: Biliary diseases known since ages constitute major portion of digestive tract disorders world over. Among these cholelithiasis being the fore runner causing general ill health, thereby requiring surgical intervention for total cure. The study was undertaken in an attempt to compare the hemodynamic changes in patient undergoing laparoscopic cholecystectomy using different intra-abdominal pressures created due to carbon dioxide insufflation. The patients were randomly allocated to one of the three groups in which different levels of intra-abdominal pressures (8–10 mmHg,11–13 mmHg and 14 mmHg and above) were maintained. The base line parameters monitored were heart rate, non invasive blood pressur(systolic and mean)and end tidal carbon dioxide. All the parameters were monitored at various intervals i.e. Immediately during insufflation, 5 min, 10 min, 20 min, 30 min after CO2 insufflation and after every 10 min if surgery exceeds 30 min, at exsufflation,10 min after CO2 exsufflation. Patients were ventilated with Pedius Drager Ventilator keeping tidal volume 8–10 ml/kg and respiratory rate 12–14 breaths/min. During surgery patients were placed in reverse Trendlenburg position (head up) at 15 °. The results obtained were evaluated statistically and analyzed. Baseline characteristics were found to be comparable. Hemodynamic variables were reported as mean and standard deviation. Statistical significance among groups was evaluated using Analysis of Variance and unpaired student t test (two tailed). Inter-group comparisons were made using Bonferroni test. A p-value of <0.05 was considered as statistically significant. In all the three groups the mean heart rate (baseline 84.08 ± 12.50, 87.96 ± 15.73 and 86.92 ± 17.00 respectively) increased during CO2 insufflation and the rise in heart rate continued till exsufflation after which it decreased and at 10 min after exsufflation the heart rates were comparable with the baseline. The inter-group comparison of mean heart rate between I & III was statistically significant at 10, 20, 30 min after CO2 insufflation which continued at exsufflation and 10 min after CO2 exsufflation [p < 0.05]. The inter-group comparison between I & III showed statistically significant difference in systolic blood pressure at 10, 20, 30 min after CO2 insufflation, at exsufflation and 10 min after exsufflation [p = 0.0001] and mean arterial pressure at 5, 10, 20, 30 min after CO2 insufflation, at exsufflation and 10 min after exsufflation [p = 0.0001]. Comparison between Group I and Group III & between Group II and Group III showed highly significant statistical difference in EtCO2 immediately after insufflation and the same trend was seen till the completion of surgery and even 10 min after exsufflation [p = 0.001]. The conclusion drawn from the study was that laparoscopic cholecystectomy induces significant hemodynamic changes intraoperatively, the majority of pathophysiological changes are related to cardiovascular system and are caused by CO2 insufflation .A high intra-abdominal pressure due to CO2 insufflation is associated with more fluctuations in hemodynamic parameters and increased peritoneal absorption of CO2 as compared to low intraabdominal pressure so low pressure pneumoperitoneum is feasible for laparoscopic cholecystectomy and minimizes the adverse hemodynamic effects of CO2 insufflation.

    ABSTRACT: Single-incision laparoscopic surgery also known as laparo-endoscopic single-site surgery for cholecystectomy is performed using a single umbilical skin incision through which a laparoscope and two instruments are introduced. It is virtually a “scarless” surgery. The present study was undertaken to evaluate the efficacy of single-incision laparoscopic cholecystectomy using conventional instruments and compare it with three-port laparoscopic cholecystectomy. Thirty patients who underwent single-incision cholecystectomy were compared to an equal number of patients who underwent three-port cholecystectomy. Both groups were assessed on the basis of operative time, intraoperative complications, postoperative pain, ambulation, hospital stay, and body image at first and third week. Single-incision cholecystectomy had the advantage of less postoperative pain, early ambulation, and better body image as compared to three-port cholecystectomy; the results being statistically significant. There was no statistically significant difference in operative time and hospital stay between the two groups. Single-incision laparoscopic cholecystectomy using conventional instruments is a safe and effective surgery. It gives better cosmetic results, almost scarless surgery, without increasing the cost of surgery.

    ABSTRACT: Insufflation of carbon dioxide during laparoscopic cholecystectomy leads to postoperative shoulder tip pain. The origin of shoulder pain is commonly assumed to be due to overstretching of the diaphragmatic muscle fibres owing to a high carbon dioxide pressure. To study the frequency and intensity of post operative shoulder tip pain in laparoscopic cholecystectomy and compare low and standard pressure pneumoperitoneum during laparoscopic cholecystectomy with respect to post operative shoulder tip pain. Patients admitted in the department of surgery for elective cholecystectomy were enrolled in the study. The patients were randomly allocated to two groups (group A and group B). In group A (n = 50), low pressure pneumoperitoneum (8 mm Hg) and in group B (n = 50), standard pressure pneumoperitoneum (14 mm Hg) was generated during laparoscopic cholecystectomy. Postoperative shoulder tip pain was assessed at 4, 8 and 24 h after operation by the Visual Analogue Scale of Pain. 14 patients (28%) in group B complained of post operative shoulder tip pain as compared to only 5 patients (10%) in group A. The mean intensity of post operative shoulder tip pain assessed by visual analogue scoring scale at 4, 8 and 24 h was less in group A as compared to group B, although statistical significance was seen only at 4 h. Analgesic requirements and the mean length of post operative stay in the hospital were also less in group A as compared to group B. Low pressure laparoscopic cholecystectomy (LPLC) significantly decreases the frequency and intensity of postoperative shoulder tip pain. LPLC decreases the demand for postoperative analgesics, decreases postoperative hospital stay and hence improves the quality of life in the early stage of postoperative rehabilitation.
