Abstract
AIMS: This study aimed at comparing the pre-, intra-, and early postoperative outcomes, between patients who underwent PVB vs general anesthesia (GA) during LSG. Follow-up of weight loss at least 1 year postoperatively was also evaluated. METHODS: A cohort study was conducted by selecting all patients who underwent LSG under PVB and GA at Makassed General Hospital between 2010 and 2016. Demographic, social, pre-op health status, body mass index (BMI), operative time, postoperative pain and pain medication consumption, postoperative complications and length of hospital stay, all were studied. Follow-up weight loss was collected up to 5 years postoperatively. Data entry, management, and descriptive and inferential statistics were performed using SPSS. RESULTS: A total of 210 participants were included in this study of which 48 constituted the PVB group and 162 patients composed the GA group. Both groups were similar in baseline demographic factors, with patients in PVB suffering from higher number and advanced stage of comorbidities than the GA group. Mean operative time was similar in between the two groups with 80 ± 20 min for PVB and 82 ± 18 min for GA group. Intraoperative complications were scarce among both study groups. GA group requested a second dose of analgesia earlier than PVB group. After at least 1 year postoperatively, the mean percentage of excess weight loss was 81.35 ± 15.5% and 77.89 ± 14.3% for the PVB and GA groups, respectively, P value 0.45. CONCLUSION: Outcomes of LSG under both types of anesthesia (PVB alone and GA alone) were found to be comparable. However, the need for analgesia was significantly less in the PVB group compared to GA group.
