PURPOSE: Minimally invasive surgical technics have benefits such as decreased pain, reduced surgical trauma, and increased potential to perform as day case surgery, and cost benefit. The primary aim of this prospective, randomized, controlled study was to compare the effects of single incision laparoscopic cholecystectomy (SILC) and conventional laparoscopic cholecystectomy (CLC) procedures regarding postoperative pain. METHODS: Ninety adult patients undergoing elective laparoscopic cholecystectomy were included in the study. Patients were randomized to either SILC or CLC. Patient characteristics, postoperative abdominal and shoulder pain scores, rescue analgesic use, and intraoperative and early postoperative complications were recorded. RESULTS: A total of 83 patients completed the study. Patient characteristics, postoperative abdominal and shoulder pain scores and rescue analgesic requirement were similar between each group except with the lower abdominal pain score in CLC group at 30th minute (P = 0.04). Wound infection was seen in 1 patient in each group. Nausea occurred in 13 of 43 patients (30%) in the SILC group and 8 of 40 patients (20%) in the CLC group (P > 0.05). Despite ondansetron treatment, 6 patients in SILC group and 7 patients in CLC group vomited (P > 0.05). CONCLUSION: In conclusion, in patients undergoing laparoscopic surgery, SILC or CLC techniques does not influence the postoperative pain and analgesic medication requirements. Our results also suggest that all laparoscopy patients suffer moderate and/or severe abdominal pain and nearly half of these patients also suffer from some form of shoulder pain.

PURPOSE: The efficacy of octreotide in the treatment of acute pancreatitis is controversial. Octreotide treatment for acute pancreatitis often shows poor correlation between results obtained in experimental studies and results of clinical trials. In a clinical setting, there is always a delay between the onset of the disease and initiation of the octreotide treatment. The aim of this study is to investigate the relationship between the beginning of treatment and alteration in effectiveness of octreotide. METHODS: Acute pancreatitis was induced by pancreatic duct ligation in 50 rats. The rats were randomly divided into five groups. Octreotide was not used in group 1 (control group). Only single dose (4 microg/kg) octreotide was administered subcutaneously to rats in group 2, having induced pancreatitis. Octreotide treatment was begun at different times (8th, 24th, 48th hour) in three other groups and continued treatment at a dosage of 4 microg/kg t.i.d. The animals were sacrificed at the end of the 72nd hour and blood and tissue samples were collected. RESULTS: Leukocyte count and plasma amylase values were less in groups 2 and 3. Hemorrhagic focuses were encountered less at pancreas tissues in group 3. Pancreatic necrosis and alveolar capillary basal membrane damage were lower in groups 3 and 4. No difference was found in fasting blood glucose, calcium and hematocrit. CONCLUSION: Octreotide had benefical effects in acute pancreatitis when octreotide treatment was begun in the first 24 hours.

PURPOSE: The aim of the present study was to evaluate the predictive value of volume of the specimen/body mass index (VS/BMI) ratio for recurrence after surgical therapy of pilonidal disease. METHODS: Ninety-eight patients with primary pilonidal disease were enrolled in this study. The VS/BMI ratio was calculated for each patient. This ratio was defined as the specimen index (SI). VS, BMI and SI were evaluated to determine whether there is a relationship between these parameters and recurrence of pilonidal disease. In addition, the predictive ability of SI for recurrence was analyzed by receiver operating characteristic (ROC) curve. RESULTS: VS and SI were found to be higher in patients with recurrence. ROC curve analysis showed that VS and SI are predictive factors for recurrence in patients treated with primary closure, nevertheless our new index had higher sensitivity and specificity than VS (sensitivity 85.7% vs 71.4% and specificity 90.7% vs 85.1%, respectively). The cut-off level for the greatest sensitivity and specificity for SI was 1.29. CONCLUSION: Recurrence is higher in patients with high VS regardless of the operation method. SI may be a predictive value in patients treated with primary closure.
