ABSTRACT
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. Demographics, waiting time to surgery, intra-operative details and outcome data were compared between the two cohorts. Indications for surgery were grouped as inflammatory (acute cholecystitis, gallstone pancreatitis, CBD stone with cholangitis) or non-inflammatory (biliary colic, gallbladder polyps, CBD stone without cholangitis). A p value of <0.05 was used for statistical significance. Out of the 159 patients included, 106 were operated pre-pandemic and 53 during the pandemic recovery phase. Both groups had similar age, gender, ASA-grades and BMI. In the pre-pandemic group, 68 (64.2%) were operated for a non-inflammatory pathology compared to 19 (35.8%) from the recovery phase cohort (p < 0.001). The waiting time to surgery was significantly higher amongst patients operated during the recovery phase (p = 0000.1). Less patients had complete cholecystectomy during the pandemic recovery phase (p = 0.04). There were no differences in intraoperative times and patient outcomes. These results demonstrate the impact of COVID-19 related delays to our cohort, however due to the retrospective nature of this study, the current results need to be backed up by higher evidence in order for strong recommendations to be made.
ABSTRACT
Background The coronavirus pandemic has caused global disruption to all aspects of life. This disturbance has been most notable in the medical world. Political, societal, medical, and behavioral alterations have forced emergency surgical practices to adapt. This study investigated the impact of coronavirus 2019 (COVID-19) at a busy surgical center. Methodology This is a retrospective observational study. Three study periods were analyzed: pre-COVID, first wave, and second wave. Data were collected on referrals, diagnoses, investigations, management pathways, outcomes, patient behavior, and consultant practice. A one-way analysis of variance (ANOVA test) was used for the analysis of parametric data and the Mann-Whitney U test for non-parametric data. Results Declining numbers of patients presented across the three periods. There was a severe disruption in performing emergency general surgeries during the first wave, propagated by alterations in clinical decision-making, as well as fluctuations in societal and patient behavior. Despite the effects of the second wave being significantly more profound in terms of hospitalization and COVID-related mortality, a paradoxical, gradual return to the norm was noted, which was seen in referral pathways, imaging decisions, and management strategies. Conclusion Our data is suggestive of society, both within and outside the medical sphere, adjusting to life with COVID-19.
ABSTRACT
Background COVID-19 has a significant impact on elective surgery for benign disease. When routine services resumed in April 2021, surgeons were faced with higher number of complicated cases. The aim of this study is to examine the effect of COVID-19 related delays on the outcomes of patients undergoing elective laparoscopic cholecystectomy (LC) in an upper gastrointestinal unit in the UK. Methods Data were collected retrospectively on consecutive patients undergoing elective LC between 1/3/19 to 1/5/19 (Pre-COVID) and 1/4/21 to 11/6/21 (resumption of elective operating following COVID). The indications for surgery, intraoperative details, postoperative complications, length of stay (LoS) and 30- day readmission were compared between the two cohorts. We divided indications for surgery as inflammatory (acute cholecystitis, gallstone pancreatitis, CBD stone with cholangitis) vs non-inflammatory (biliary colic, gallbladder polyps, CBD stone without cholangitis). Data were analysed using the Mann-Whitney U-test and Chi-square or Fisher’s exact test. A p value of < 0.05 was used for statistical significance. Results 159 patients were analysed, 106 in Pre-COVID vs 53 in Post-COVID. Both cohorts had similar age, gender, ASA-grade, BMI. 68 (64.2%) of the pre-COVID cohort were operated for a non-inflammatory pathology compared to 19(35.8%) of the post-COVID cohort (p < 0.001). Less patients had total cholecystectomy (subtotal and failed surgery) in the post-COVID cohort [49(92.5%) vs 159 (100%) p = 0.01]. There was no difference in the operating time, conversion to open surgery, the need for drains, and no difference in the Clavien-Dindo grade complications. Two patients in pre- COVID cohort (1.8%) required re-operation for bile-leak and bowel injury and two in the post COVID cohort (3.7%) for bleeding and CBD-injury. There was no difference in day case discharge or 30-day readmission rate. Conclusions Surgery in the post-COVID cohort was associated with a higher incidence of inflammatory biliary disease, subtotal cholecystectomy and procedure abandoned. Although the numbers in our study are small they highlight the need for enhanced preoperative assessment in elective biliary surgery as the NHS emerges from the acute phase of the pandemic.
