The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

Short-and long-term outcomes of coronavirus disease 2019 patients presenting with diarrhea

Gastrointestinal (GI) manifestations of the coronavirus disease 2019 (COVID-19) pandemic are frequently observed in SARS-CoV-2-infected individuals at distinct time intervals after the initial diagnosis. Psychological distress in the form of anxiety, burnout, and depression is regarded as a common complication of COVID-19, but also as a risk factor for the development and exacerbation of irritable bowel syndrome (IBS), which is highly prevalent among COVID-19 patients and the general population. The pathophysiological mechanisms culminating in the diagnosis of IBS are yet to be fully understood, however, factors including gut–brain interaction, COVID-19-related intestinal damage, and other external influences might play a role in this process. While long-term GI complications of COVID-19 such as IBS are speculated to develop as a result of a multifaceted interaction between the virus itself with the host, in addition to the effects of psychological distress, further research on this topic is warranted. The purpose of this study was to explore possible factors correlating with the development of IBS and depression during the follow-up period post-COVID-19 infection
