Percutaneous cholecystostomy as bridge to surgery vs surgery in unfit patients with acute calculous cholecystitis: A systematic review and meta-analysis

Background: Acute cholecystitis is one of the most common causes of acute abdomen. Early laparoscopic cholecystectomy is the gold standard treatment, still burdened by a risk of intraoperative biliary duct injury. An alternative strategy to manage patients with severe acute cholecystitis is the percutaneous gallbladder drainage (PGBD). Methods: The Italian Society of Emergency Surgery and Trauma performed a systematic review and meta-analysis with the aim to clarify controversies about the preoperative use of PGBD. We extracted 32 studies: 9 Randomized Control Trial Studies (RCTs) and 23 no RCTs. Results of critical outcomes: The incidence of post-operative complications was lower in the PGBD associated at LC than in the LC alone (RCTs: RR 0.28, 95% CI 0.14 to 0.56, I2 1/4 63%). The incidence of the post-operative biliary leakage was higher in late PGBD' group (RCTs: RR 0.18, 95% CI 0.04 to 0.80). Results of other outcomes: The incidence of intraabdominal abscess, blood loss, conversion to open, subtotal cholecystectomy, operative time and wound infection was lower in PGBD' group. The total hospital stay was the same. Conclusion: A strong recommendation is performed to the use of the PGBD + LC than upfront LC to reduce biliary leakage (recommendation "strong positive") in high risk acute cholecystitis especially in patients with higher perioperative risks or longstanding acute cholecystitis. For post-operative complications a recommendation "positive weak" sug-gests that PGBD + LC could be used than upfront LC to reduce the rate of post-operative complications. & COPY; 2022 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.
