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 = 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" suggests that PGBD + LC could be used than upfront LC to reduce the rate of post-operative complications.
