Symptoms of gallstone disease are the most common reason for cholecystectomy. Fenestration reduces the likelihood of severe inflammation or scarring after normal treatments are used, and it also enhances control over bile outflow. The goal of reconstituted cholecystectomy is to lessen symptoms like pain and jaundice without undergoing the high-risk procedures associated with more invasive procedures. The reconstituted and fenestrated procedures were assessed by a meta-analysis and systematic review. Of the five studies, 189 (34.2%) had a reconstituted subtotal cholecystectomy, and 363 (65.8%) had a fenestrated subtotal cholecystectomy, which had populations from the United States of America, the United Kingdom, Japan, and Turkey. Two individuals from three trials had bile duct injury, according to three studies. Whereas the fenestrated group reported no bile injury from 236 individuals (0%), the reconstituted group reported two bile duct injuries from 100 patients (2%). The incidence was found to be lower in the fenestrated group (OR 10.81; CI 95% 1.03-113.65; p = 0.39; I2 = 0%) than in the reconstituted group. Four studies revealed 92 cases of bile leaks: 19 out of 155 cases (12.3%) were reconstituted, and 73 out of 351 cases (20.8%) were fenestrated. Between the two groups, there was a significant difference in bile leakage (OR 0.72; CI 95% 0.23-2.32; p = 0.03; I2 = 66%). Two studies reported the establishment of fistulas following surgery in 58 patients in the reconstituted group (5.2%) and 120 patients in the fenestrated group (2.5%) (p = 0.56, I2 = 0%, and OR 0.65; CI 95% 0.12-3.38); however, there was no statistically significant difference between the groups. Following a fenestrated partial cholecystectomy, postoperative bile leakage, fistula development, wound infection, and retained stones are more prevalent. Additionally, we saw that the fenestrated method was being used more frequently for post-operative endoscopic retrograde cholangiopancreatography (ERCP). The subtotal cholecystectomy technique used should be chosen according to the surgeon's comfort level and experience with the various techniques and intraoperative findings, even if the reconstituted procedure could be preferred when feasible. To completely understand the role of each method in the general surgeon's toolkit for treating complex gallbladder (GB) patients, longer-term follow-up studies are still necessary.
