Background: /Objective: We evaluated the risk of acute cholangitis and/or cholecystitis while waiting for cholecystectomy for gallstones.
Methods: We retrospectively enrolled 168 patients who underwent cholecystectomy for gallstones after conservative therapy. We compared clinical data of 20 patients who developed acute cholangitis and/or cholecystitis while waiting for cholecystectomy (group A) with 148 patients who did not develop (group B). We investigated surgical outcomes and risk factors for developing acute cholangitis and/or cholecystitis.
Results: Preoperatively, significant numbers of patients with previous history of acute grade II or III cholecystitis (55.0% vs 10.8%; p < 0.001) and biliary drainage (20.0% vs 2.0%; p = 0.004) were observed between groups A and B. White blood cell counts (13500/μL vs 8155/μL; p < 0.001) and C-reactive protein levels (12.6 vs 5.1 mg/dL; p < 0.001) were significantly higher in group A than in group B; albumin levels (3.2 vs 4.0 g/dL; p < 0.001) were significantly lower in group A. Gallbladder wall thickening (≥5 mm) (45.0% vs 18.9%; p = 0.018), incarcerated gallbladder neck stones (55.0% vs 22.3%; p = 0.005), and peri-gallbladder abscess (20.0% vs 1.4%; p = 0.002) were significantly more frequent in group A than in group B. A higher conversion rate to open surgery (20.0% vs 2.0%; p = 0.004), longer operation time (137 vs 102 min; p < 0.001), and higher incidence of intraoperative complications (10.0% vs 0%; p = 0.014) were observed in group A, compared with group B.
Conclusion: A history of severe cholecystitis may be a risk factor for acute cholangitis and/or cholecystitis in patients waiting for surgery; it may also contribute to increased surgical difficulty.
