The service of providing index admission laparoscopic cholecystectomy (IALC), as recommended by NIC guidelines, often falls short in nontertiary centres because of a combination of limited resources and financial constraints. This retrospective study in a single-centre District General Hospital included 50 patients, eligible to undergo IALC, and calculated potential savings from performing IALC on the day of admission by considering admission tariffs, bed, and operating costs. The IALC was provided in 19 patients (38%), with a mean delay from admission to operation of (median) 3days. Mean surplus tariff was £1421 and £1571 in IALC and non-IALC groups, respectively. Performing immediate IALC (on the day of admission) for acute cholecystitis (AC) is predicted to increase mean surplus tariff to £2132 per patient, raising total predicted annual surplus by £53000. Immediate IALC is also predicted to reduce waiting time for day-case LC by freeing up 53day-case slots, attracting additional £95600 annually, along with freeing up many inpatient bed days. This study demonstrates that reduction of preoperative stay in AC by expediting operations in every eligible patient promises significant surplus revenue. Additional advantages include reducing inpatient bed days and freeing up operating lists that are otherwise taken up by patients for interval cholecystectomy.
