Abstract

BACKGROUND: Patients undergoing active cancer therapy or with metastatic cancer are at increased risk for acute cholecystitis and often present to general surgeons for evaluation and management. There is a paucity of data regarding the treatment processes used in these patients and the clinical outcomes achieved. Optimal management of acute cholecystitis in patients with cancer requires understanding their unique risk profile and options for treatment.

METHODS: Emergency general surgery data were collected at 10 hospitals from July 1, 2019, to February 29, 2024. Patients presenting with acute cholecystitis were selected for analysis. Propensity score matching was used to create matched cohorts of patients by the presence or absence of an active malignancy. The primary outcome was 30-day mortality. Secondary outcomes included complications, length of stay, readmission, and discharge disposition. Processes investigated include treatment modality, time to operation, and surgical technique.

RESULTS: The analysis included 8,673 patients. Mean age was 53.2 ± 19 years, 61.4% were female, and 17.8% were non-White. In total, 3.3% of patients had an active malignancy. Risk-adjusted 30-day mortality was higher in the cancer cohort (odds ratio: 5.85, 95% confidence interval: 2.38-14.4, P < .001). Patients with cancer also had higher rates of infectious complications (odds ratio: 2.55, 95% confidence interval: 1.54-4.2, P < .001), including sepsis (odds ratio: 2.95, 95% confidence interval: 1.61-5.39, P < .001) and pneumonia (odds ratio: 6.67, 95% confidence interval: 1.75-25.3, P < .005). Patients with cancer were more likely to receive nonoperative management (odds ratio: 2.85, 95% confidence interval: 2.11-3.84, P < .001).

CONCLUSION: Patients with cancer presenting with acute cholecystitis experience worse clinical outcomes after controlling for other factors. Furthermore, there is variation in the treatment process with increased rates of nonoperative management. These results have implications for the management of this population, particularly in relation to the impact on concurrent oncologic treatment plans.
