MATERIALS AND METHODS: This is a prospective single centre randomised single blinded comparative study conducted in HUSM. The primary endpoints for this study are the overall complete stone clearance rate and complication rate, while the secondary outcome for this study are duration of procedure and rate of usage of adjunct methods. Objective data analysis is conducted using independent sample t-test and chi-squared test.
RESULTS: A total of 66 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis which is CBD stone. 34 patients were allocated to EST plus EPLBD arm (n=34), and 32 patients were in EST alone arm (n=32) using randomisation method. For intention to treat, patients from EST alone arm that unable to achieve complete stone clearance will be switched to EST plus EPLBD arm. The overall complete stone removal rate for both groups were comparable (EST plus EPLDB: 100% versus EST alone: 93.8%; p= 0.139). The two patients from EST alone group (6.2%) that unable to achieve complete stone clearance were converted to EST plus EPLBD group for intention to treat and able to achieve complete stone clearance by EST plus EPLBD. For procedural time, both arms are comparable as well (EST plus EPLDB: 15.8 minutes vs EST alone: 15.5 minutes; p= 0.860). Complications such as pancreatitis occurred in one patient in EST plus EPLBD arm (EST plus EPLDB: 2.9 % vs EST alone: 0 %; p= 0.328), and bleeding occurred in one patient in EST alone arm (EST plus EPLDB: 0 % vs EST alone: 3.1 %; p= 0.299) , but it is not statistically significant. No perforation or cholangitis complication occurred in both groups. No adjunct usage was observed in both groups.
CONCLUSION: In this study with limited sample size, both EST plus EPLBD and EST alone are effective and has comparable procedural time in removing CBD stone. Even though both methods are equally effective, EPLBD plus EST is an alternative solution if complete stone clearance is unable to achieve via EST alone.
MATERIAL AND METHODS: Sixty-two patients with symptomatic gallstones were recruited within a year. They were randomized into overnight stay and daycare groups. The outcomes and post-operative complications were analyzed.
RESULTS: Fifty-eight patients were eligible for analysis and four patients were excluded because of conversion to open cholecystectomy. All patients in daycare group reported no fever but two patients in the overnight stay group complaint of post-operative fever (p=0.150). The mean pain score using Visual Analogue Score (VAS) in daycare group was 2.93 but in the overnight stay was recorded as 3.59 (p=0.98). Five patients had post-operative nausea and vomiting (PONV) in daycare group compared to 2 patients in the overnight stay group (p=0.227). Patient's satisfaction were higher in the daycare group (p=0.160). All patients in daycare group were back at work within a week but in overnight stay, 11 patients had to stay off work for more than one week (p=0.01).
CONCLUSIONS: Daycare laparoscopic cholecystectomy is safe and feasible. The satisfaction of daycare surgery is higher than overnight stay group. Patients' selection is an important aspect of its success.
METHODS: Patients with mild to moderate ABP were prospectively randomized to either an early cholecystectomy versus a delayed cholecystectomy group. Recurrent biliary events, peri-operative complications, conversion rate, length of surgery and total hospital length of stay between the two groups were evaluated.
RESULTS: A total of 72 patients were enrolled at a single public hospital. Of them, 38 were randomized to the early group and 34 patients to the delayed group. There were no differences regarding peri-operative complications (7.78% vs 11.76%; p = 0.700), conversion rate to open surgery (10.53% vs 11.76%; p = 1.000) and duration of surgery performed (80 vs 85 minutes, p = 0.752). Nevertheless, a greater rate of recurrent biliary events was found in the delayed group (44.12% vs 0%; p ≤ 0.0001) and the hospital length of stay was longer in the delayed group (9 vs 8 days, p = 0.002).
CONCLUSION: In mild to moderate ABP, early laparoscopic cholecystectomy reduces the risk of recurrent biliary events without an increase in operative difficulty or perioperative morbidity.
