Laparoscopic cholecystectomy for acute cholecystitis: an analysis of early versus delayed cholecystectomy and predictive factors for conversion.

BACKGROUND: There is an increasing preference for early laparoscopic cholecystectomy (ELC) as compared to delayed LC (DLC) in the management of acute cholecystitis (AC). Conversion to open cholecystectomy (LOC) remains an important outcome. We aim to compare ELC and DLC outcomes and identify LOC predictors. METHODS: Retrospective analysis of 466 patients who underwent LC for AC from June 2010 to June 2015 was performed. Patients were divided into ELC and DLC groups, defined as LC performed within 7 days and between 4 to 24 weeks of symptom onset, respectively. Peri-operative outcomes and predictors for LOC were analyzed. RESULTS: Conversion rates were comparable [ELC, 8.6% vs. DLC, 8.0%] (P=0.867). While median operative time was longer in ELC (101.5 min [83.0-130.1]) than DLC (88.0 min [62.3-118.8]) (P<0.001), intraoperative (ELC, 1.9% vs. DLC, 3.0%; P=0.541) and postoperative morbidity (ELC, 13.5% vs. DLC, 12.5%; P=0.688) was comparable. Median total length of stay (LOS) was shorter in ELC (4 days [3-6]) than DLC (5 days [4-9]) (P<0.001). Univariate analysis showed increased age (LC, 57 [45-66] vs. LOC, 60 [56-72]; P=0.016), presence of comorbidities (LC, 69.0% vs. LOC, 87.8%; P=0.009), previous abdominal surgery (LC, 6.1% vs. LOC, 17.1%; P=0.014), fever (P=0.001), Murphy's sign (P=0.005) and lower albumin (LC, 42.0 [39.0-45.0] vs. LOC, 40.0 [36.0-43.0]; P=0.003) to be predictors for LOC. CONCLUSIONS: ELC provides shorter LOS and eliminates the risk of gallstone-related morbidity while awaiting surgery. It should be advocated for patients with AC. The presence of comorbidities, increased age, previous abdominal surgery and low albumin are predictors for conversion.

Delayed Presentation of Acute Cholecystitis: Comparative Outcomes of Same-Admission Versus Delayed Laparoscopic Cholecystectomy.

INTRODUCTION: Studies have shown that same-admission laparoscopic cholecystectomy (SALC) is superior to delayed laparoscopic cholecystectomy (DLC) for acute cholecystitis (AC). However, no studies have compared both modalities in patients with delayed presentation. The aim of the study was to compare outcomes between SALC and DLC in AC patients with more than 7-day symptom duration. METHODS: A retrospective analysis of 83 AC patients who underwent LC after presenting with >7 days of symptoms from June 2010 to June 2015 was performed. Patients were divided into L-SALC and L-DLC, defined as LC performed within the same admission and between 4 and 24 weeks after discharge, respectively. Peri-operative outcomes were evaluated. RESULTS: In L-SALC patients, the intra-operative severity was higher (p < 0.001) and median operative time was longer (L-SALC, 107 min (46-220) vs L-DLC, 95 mins (25-186)) (p = 0.048). Conversion rates were also higher in L-SALC than that in L-DLC (L-SALC, 21.4% vs L-DLC, 4.9%) (p = 0.048). While post-operative morbidity was similar, L-SALC was associated with a longer post-operative length of stay as compared to L-DLC (L-SALC, 2 (1-17) vs L-DLC, 1 (1-6)) (p < 0.001). CONCLUSION: DLC provides lower conversion rates and shorter length of stay in AC patients presenting beyond 7 days of symptoms. This group of patients should be offered DLC.

Same admission laparoscopic cholecystectomy for acute cholecystitis: is the "golden 72 hours" rule still relevant?

BACKGROUND: Studies have shown that same admission laparoscopic cholecystectomy (SALC) is superior to delayed laparoscopic cholecystectomy for acute cholecystitis (AC). While some proposed a"golden 72-hour" for SALC, the optimal timing remains controversial. The aim of the study was to compare the outcomes of SALC in AC patients with different time intervals from symptom onset. METHODS: A retrospective analysis of 311 patients who underwent SALC for AC from June 2010-June 2015 was performed. Patients were divided into three groups based on the time interval between symptom onset and surgery: <4 days (E-SALC), 4-7 days (M-SALC), >7 (L-SALC). RESULTS: The mean duration of symptoms was 2(1-3), 5(4-7) and 9 (8-13) days for E-SALC, M-SALC and L-SALC, respectively (p < 0.001). Conversion rates were higher in the L-SALC group [E-SALC, 8.2% vs M-SALC, 9.6% vs L-SALC, 21.4%] (p = 0.048). The total length of stay was longer in patients with longer symptom duration [E-SALC, 4 (2-33) vs M-SALC, 2 (2-23) vs L-SALC, 7 (2-49)] (p < 0.001). CONCLUSION: Patients with AC presenting beyond 7 days of symptoms have higher conversion rates and longer length of stay associated with SALC. However, patients with less than a week of symptoms should be offered SALC.
