Effect of surgical timing on outcomes after cholecystectomy for mild gallstone pancreatitis

Management of Gallstone Pancreatitis: A Review

Importance

Gallstone pancreatitis (GSP) is the leading cause of acute pancreatitis, accounting for approximately 50% of cases. Without appropriate and timely treatment, patients are at increased risk of disease progression and recurrence. While there is increasing consensus among guidelines for the management of mild GSP, adherence to these guidelines remains poor. In addition, there is minimal evidence to guide clinicians in the treatment of moderately severe and severe pancreatitis.

Observations

The management of GSP continues to evolve and is dependent on severity of acute pancreatitis and concomitant biliary diagnoses. Across the spectrum of severity, there is evidence that goal-directed, moderate fluid resuscitation decreases the risk of fluid overload and mortality compared with aggressive resuscitation. Patients with isolated, mild GSP should undergo same-admission cholecystectomy; early cholecystectomy within 48 hours of admission has been supported by several randomized clinical trials. Cholecystectomy should be delayed for patients with severe disease; for severe and moderately severe disease, the optimal timing remains unclear. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) is only useful for patients with suspected cholangitis or biliary obstruction, although the concomitance of these conditions in patients with GSP is rare. Modality of evaluation of the common bile duct to rule out concomitant choledocholithiasis varies and should be tailored to level of concern based on objective measures, such as laboratory results and imaging findings. Among these modalities, intraoperative cholangiography is associated with reduced length of stay and decreased use of ERCP. However, the benefit of routine intraoperative cholangiography remains in question.

Conclusions and Relevance

Treatment of GSP is dependent on disease severity, which can be difficult to assess. A comprehensive review of clinically relevant evidence and recommendations on GSP severity grading, fluid resuscitation, timing of cholecystectomy, need for ERCP, and evaluation and management of persistent choledocholithiasis can help guide clinicians in diagnosis and management.

Percutaneous cholecystostomy tube placement as a bridge to cholecystectomy for grade III acute cholecystitis: A national analysis

Introduction

Percutaneous cholecystostomy (PCT) is an alternative to cholecystectomy (CCY) in high-risk surgical candidates with severe acute cholecystitis. A subset of these patients ultimately undergo delayed CCY. We therefore compared outcomes of delayed CCY in patients with grade III acute cholecystitis who received a PCT on index admission, to those who did not.

Methods

Non-elective adult hospitalizations for grade III acute cholecystitis that underwent delayed CCY were identified in the 2016-2020 Nationwide Readmission Database. Patients who received a PCT during their index admission comprised the PCT group (others: Non-PCT). Outcomes were assessed for the CCY hospitalization. Entropy balancing was used to generate sample weights to adjust for differences in baseline characteristics. Regression models were created to evaluate the association between PCT and the outcomes of interest.

Results

Of an estimated 13,782 patients, 13.3 % comprised PCT. Compared to Non-PCT, PCT were older (71.1 ± 13.1 vs 67.4 ± 15.3 years) and more commonly in the highest income quartile (22.5 vs 16.1 %, both p < 0.001). After risk adjustment, PCT was associated with reduced odds of respiratory (AOR 0.67, CI 0.54-0.83) and infectious (AOR 0.77, CI 0.62-0.96) complications after eventual CCY. Finally, PCT had comparable pLOS (β +0.31, CI [-0.14, 0.77]) and operative hospitalization costs (β $800, CI [-2300, +600]).

Conclusion

In the present study, PCT was associated with decreased odds of perioperative complications and comparable resource utilization upon readmission CCY. Our findings suggest that PCT may be helpful in bridging patients with grade III acute cholecystitis to eventual CCY.
