Type II Gallbladder Perforation: A Management Conundrum or a Surgical Indecision?

Area of Science:

• Gastroenterology
• Surgical Innovation
• Medical Imaging

Background:

• Gallbladder perforation (GBP) is a rare but serious complication of acute cholecystitis.
• Niemeier Type II, with localized perforation and abscess, is the most common subtype.
• Standardized management guidelines for Type II GBP are lacking.

Purpose of the Study:

• To evaluate clinical, radiologic, and comorbidity factors influencing treatment selection for Type II GBP.
• To assess outcomes associated with different management strategies.

Main Methods:

• Retrospective review of 91 radiologically diagnosed GBP cases (2014-2022).
• Classification by Niemeier system; Type II cases analyzed by management: cholecystectomy, cholecystostomy, IR drainage, or antibiotics.
• Data included demographics, Charlson Comorbidity Index (CCI), CT findings, length of stay, reintervention, readmissions, and mortality.

Main Results:

• 72 cases were Type II GBP. Management varied: cholecystectomy (13%), cholecystostomy (17%), IR drainage (24%), antibiotics alone (46%).
• Surgery patients had lower CCI; conservative strategies were used in older, higher comorbidity patients.
• Gallbladder distension predicted cholecystostomy; loculated collections predicted IR drainage. CCI > 5.5 excluded patients from cholecystectomy. No significant differences in mortality, LOS, or reintervention rates between groups.

Conclusions:

• Comorbidity burden, age, and CT morphology dictate management of Type II GBP.
• Individualized nonoperative strategies yield comparable short- to intermediate-term outcomes in high-risk patients.
• Larger multicenter studies are needed to establish evidence-based guidelines.
