Introduction

This study aims to compare the patient demographics and management of acute manifestations of gallstone disease during the COVID-19 pandemic with an equivalent period in 2019 and assess the differences in recurrence patterns throughout the first and second waves of the pandemic in the UK.

Methods

A retrospective cohort study of all adult patients aged >16 years presenting to the emergency department at a large District General Hospital with symptoms related to gallstones. Data were obtained from electronic patient records. The primary outcomes were incidence and management of gallstone disease, while secondary outcomes studied included length of stay, readmission rate, and recurrence. Data were tabulated and analyzed using Excel (Microsoft, 2016 version). Chi-square and t-test were used as appropriate. One way ANOVA test was used to compare data of three groups.

Results

Fifty-one patients presented during the period of first-wave and 105 patients during the second wave as compared to 71 patients in the study period in 2019. The median age of patients during the first wave of COVID was significantly higher than pre-COVID in the second wave. During both the waves of the pandemic, there was no significant difference in patients presenting with cholecystitis compared with 2019 (47 and 94 in the first and second wave, respectively, versus 60 in 2019; p-value 0.39). There was no significant increase in the use of cholecystostomy, and the use of radiological investigations was comparable. There was no significant difference in recurrence and readmissions. The majority of the patients still await surgery.

Conclusion

During the pandemic, older patients with higher co-morbidity presented with acute gallstone disease. Conservative management was effective in the management of these patients.

COVID-19 has transformed surgical care, yet little is known regarding implications for bariatric surgery.

We sought to characterize the effect of COVID-19 on bariatric surgery delivery and outcomes.

The Metabolic and Bariatric Accreditation and Quality Improvement Program (MBSAQIP) collects data from 885 centers in North America.

The MBSAQIP database was evaluated with 2 cohorts described: the COVID-19 and the pre–COVID-19, with patients receiving surgery in 2020 and 2015–2019, respectively. Yearly operative trends were characterized, and bivariate analysis compared demographics and postoperative outcomes. Multivariable modeling evaluated 30-day readmission, reintervention, and reoperation rates and factors associated with undergoing Roux-en-Y gastric bypass.

We evaluated 834,647 patients, with 155,830 undergoing bariatric surgery during the 2020 pandemic year. A 12.1% reduction in total cases (177,208 in 2019 versus 155,830 in 2020; P < .001) and 13.8% reduction in cases per center occurred (204.2 cases per center in 2019 versus 176.1 cases per center in 2020; P < .001). Patients receiving bariatric surgery during the pandemic were younger and had fewer co-morbidities. Use of sleeve gastrectomy increased (74.5% versus 72.5%; P < .001), and surgery during COVID-19 was associated with reduced Roux-en-Y gastric bypass procedure selection (odds ratio = .83; 95% CI: .82–.84; P < .001). Length of stay decreased significantly (1.4 ± 1.4 days versus 1.6 ± 1.4 days; P < .001), yet postoperative outcomes were similar. After adjusting for co-morbidities, patients during COVID-19 had decreased 30-day odds of readmission and reintervention and a small increase in odds of reoperation.

The COVID-19 pandemic dramatically changed bariatric surgery delivery. Further studies evaluating the long-term effects of these changes are warranted.

Purpose

It has been noted in international literature that acute surgical admissions and number of operations reduced as a result of coronavirus disease2019 (COVID-19). This study assesses the impact of the COVID-19 pandemic on the number of acute surgical admissions, operations, and length of stay (LoS) at the Sunshine Coast University Hospital (SCUH), Queensland, Australia.

Methodology

A retrospective study was conducted on patients admitted to the Acute Surgical Unit (ASU) during March and April for the years 2018, 2019, and 2020. Admission data for ASU patients in 2018 and 2019 were combined (pre-COVID) and compared with 2020 (COVID) to determine impact of the pandemic on presentations and procedures.

Results

ASU admissions reduced in 2020 (461 patients) compared with pre-COVID years (mean: 545 patients per year). There was an increase in the number (%) of operations performed in 2020, 175 patients (38%) compared with pre-COVID years, mean 158 patients (29%), p = 0.001. There was a significant decrease in the number (%) of functional presentations in 2020, 29 patients (6.3%) compared with pre-COVID years, mean 105 patients (9.6%), p = 0.04. LoS was not significantly different (52 hours vs. 54 hours, p = 0.11).

Conclusion

COVID-19 has reduced the absolute number of acute surgical admissions at SCUH. This effectively reduced triage workload. Contrary to the literature, this study did not demonstrate a reduction in the number of operations or change in LoS. These data could be used by health administrators to help with resource allocation during future pandemics.

The ongoing coronavirus disease 2019 (COVID-19) pandemic has significantly disrupted both elective and acute medical care. Data from the early months suggest that acute care patient populations deferred presenting to the emergency department (ED), portending more severe disease at the time of presentation. Additionally, care for this patient population trended towards initial non-operative management.

To examine the presentation, management, and outcomes of patients who developed gallbladder disease or appendicitis during the pandemic.

A retrospective chart review of patients diagnosed with acute cholecystitis, symptomatic cholelithiasis, or appendicitis in two EDs affiliated with a single tertiary academic medical center in Northern California between March and June, 2020 and in the same months of 2019. Patients were selected through a research repository using international classification of diseases (ICD)-9 and ICD-10 codes. Across both years, 313 patients were identified with either type of gallbladder disease, while 361 patients were identified with acute appendicitis. The primary outcome was overall incidence of disease. Secondary outcomes included presentation, management, complications, and 30-d re-presentation rates. Relationships between different variables were explored using Pearson’s r correlation coefficient. Variables were compared using the Welch’s t-Test, Chi-squared tests, and Fisher’s exact test as appropriate.

Patients with gallbladder disease and appendicitis both had more severe presentations in 2020. With respect to gallbladder disease, more patients in the COVID-19 cohort presented with acute cholecystitis compared to the control cohort [50% (80) vs 35% (53); P = 0.01]. Patients also presented with more severe cholecystitis in 2020 as indicated by higher mean Tokyo Criteria Scores [mean (SD) 1.39 (0.56) vs 1.16 (0.44); P = 0.02]. With respect to appendicitis, more patients were diagnosed with a perforated appendix at presentation in 2020 [20% (36) vs 16% (29); P = 0.02] and a greater percentage were classified as emergent cases using the emergency severity index [63% (112) vs 13% (23); P < 0.001]. While a greater percentage of patients were admitted to the hospital for gallbladder disease in 2020 [65% (104) vs 50% (76); P = 0.02], no significant differences were observed in hospital admissions for patients with appendicitis. No significant differences were observed in length of hospital stay or operative rate for either group. However, for patients with appendicitis, 30-d re-presentation rates were significantly higher in 2020 [13% (23) vs 4% (8); P = 0.01].

During the COVID-19 pandemic, patients presented with more severe gallbladder disease and appendicitis. These findings suggest that the pandemic has affected patients with acute surgical conditions.

Acute cholecystitis is a common reason for emergency general surgery admission. The declaration of the COVID-19 pandemic may have resulted in treatment delays and corresponding increases in severity of disease. This study compared cholecystitis admissions and disease severity pre- and postdeclaration of pandemic.

Retrospective review of adult acute cholecystitis admissions (January 1,2020-May 31, 2020). Corresponding time periods in 2018 and 2019 comprised the historical control. Difference-in-differences analysis compared biweekly cholecystitis admissions pre- and postdeclaration in 2020 to the historical control. Odds of increased severity of disease presentation were assessed using multivariable logistic regression.

Cholecystitis admissions decreased 48.7% from 5.2 to 2.67 cases (RR 0.51 [0.28,0.96], P = 0.04) following pandemic declaration when comparing 2020 to historical control (P = 0.02). After stratifying by severity, only Tokyo I admissions declined significantly postdeclaration (RR 0.42 [0.18,0.97]), when compared to historical control (P = 0.02). There was no change in odds of presenting with severe disease after the pandemic declaration (aOR 1.00 [95% CI 0.30, 3.38] P < 0.99) despite significantly longer lengths of symptoms reported in mild cases.

Postpandemic declaration we experienced a significant decrease in cholecystitis admissions without corresponding increases in disease severity. The pandemic impacted healthcare-seeking behaviors, with fewer mild presentations. Given that the pandemic did not increase odds of presenting with increased severity of disease, our data suggests that not all mild cases of cholecystitis progress to worsening disease and some may resolve without medical or surgical intervention.

The New Zealand government instituted escalating public health interventions to prevent the spread of COVID‐19. There was concern this would affect health seeking behaviour leading to delayed presentation and worse outcomes. The aim of this study was to examine the effects of these interventions on rate and severity of acute general surgical admissions in Northland, New Zealand.

A retrospective comparative cohort study was performed. Two cohorts were identified: 28 February to 8 June 2020 and same period in 2019. Data for surgical admissions and operations and emergency department (ED) presentation were obtained from the hospital data warehouse. Three index diagnoses were assessed for severity.

There were 650 acute general surgical admissions in 2019 and 627 in 2020 (P 0.353). Operations were performed in 226 and 224 patients respectively (P 0.829). ED presentations decreased from 11 398 to 8743 (P < 0.001). No difference in severity of acute appendicitis (P 0.970), acute diverticulitis (P 0.333) or acute pancreatitis (P 0.803) was detected. Median length‐of‐stay, 30‐day mortality and admission diagnosis were comparable.

Despite a significant reduction in ED presentations, interventions for COVID‐19 did not result in a difference in the rate or severity of acute general surgical admissions.
