From mild to gangrenous cholecystitis, laparoscopic cholecystectomy is safe 24 hours a day.

OBJECTIVES: Laparoscopic cholecystectomy (LC) at night remains controversial. Prior studies have not controlled for disease severity. We analyzed outcomes of LC performed day vs. night while controlling for the Parkland Grading Scale for Cholecystitis (PGS). METHODS: Analysis of the AAST multicenter evaluation of cholecystitis database was performed. Exclusion criteria included non-operative cases, open operations, and missing PGS. Cases were divided based on operation start time. PGS was used to control for disease severity. Outcomes included operative time, use of bailout techniques and complications. RESULTS: Of 759 procedures identified, 16% were nighttime LC. No differences in demographics, comorbidities, physiologic variables and PGS were noted. Operative time (108.6 min vs 105.6), bailout techniques (8.3% vs 7.4%) and complications (9.9% vs 11.3%) were similar between groups. CONCLUSION: Regardless of severity, laparoscopic cholecystectomy is safe 24-h a day. Operations performed at night have a similar complication profile to those performed during the day.

Non-operative management of acute cholecystitis in the elderly.

BACKGROUND: Although cholecystectomy is the standard therapy for acute cholecystitis (AC), operative morbidity in the elderly may be high owing to medical co-morbidities and decreased physiological reserve. Outcomes of AC in the elderly have not been fully defined with regard to operative and long-term non-operative management. METHODS: Patients aged 65 years or over admitted to a tertiary care centre with a diagnosis of AC between January 2000 and December 2009 were reviewed retrospectively. Patient data, operative and postoperative details were obtained. To determine cholecystectomy rates in the non-operative group, medical records were reviewed, and patients and families were interviewed. RESULTS: A total of 290 patients underwent cholecystectomy during the index admission, of whom 59 (20·3 per cent) required conversion to open operation. Fifty-eight of these patients experienced 98 complications, including acute respiratory failure (27), pneumonia (18), myocardial infarction (16) and sepsis (15). Some 185 patients had non-operative treatment, of whom 67 underwent percutaneous cholecystostomy. Forty-four patients subsequently had elective cholecystectomy, with a complication rate of 23 per cent. One hundred and twenty-six patients were discharged without a plan for cholecystectomy; the rate of recurrent AC was 4 per cent among the two-thirds of patients followed to within 15 months of death. No deaths or major complications occurred among those with recurrent AC. CONCLUSION: Despite selection of the best elderly candidates for cholecystectomy, postoperative morbidity was significant. Medical management, with interval cholecystectomy only for recurrent AC, may be appropriate in selected patients.
