The impact of the COVID-19 pandemic on elective laparoscopic cholecystectomy: A retrospective Cohort study.

The coronavirus disease 2019 (COVID-19) pandemic had a significant impact on elective surgery for benign disease. We examined the effects of COVID-19 related delays on the outcomes of patients undergoing elective laparoscopic cholecystectomy (LC) in an upper gastrointestinal surgery unit in the UK. We have analysed data retrospectively of patients undergoing elective LC between 01/03/2019 to 01/05/2019 and 01/04/2021 to 11/06/2021.

Effect of preoperative diet regimen on liver size before laparoscopic sleeve gastrectomy in morbidly obese patients.

Background: Low caloric diet can reduce liver volume; however, there is no consensus regarding preoperative weight reduction before bariatric surgery. This study evaluates the effect of preoperative very-lowcalorie diet (VLCD) in patients undergoing laparoscopic sleeve gastrectomy (LSG).

Methods: This prospective study included patients scheduled for LSG stratified into two groups, Diet Group (n = 183) who followed a preoperative VLCD regimen for three weeks and underwent assessment of the liver lobes span before and after regimen, and Control Group (n = 138) who underwent sonographic assessment once before surgery and were operated upon without diet.
