The Management of Acute Colonic Diverticulitis in the COVID-19 Era: A Scoping Review

Surgical and non-operative treatment of acute complicated diverticulitis in a COVID hospital

Surgical treatment of acute abdomen during the SARS-CoV-2 pandemic was accompanied by an extremely high mortality rate, however, only a few studies have presented the results of acute inflammatory complications of diverticular disease (AICDD).AIM: analysis of treatment of AICDD in a COVID-19 hospital.PATIENTS AND METHODS: the retrospective study included 78 patients with acute diverticulitis (AD) from a COVID hospital, confirmed by CT or intraoperative revision. Assessment of COVID pneumonia, comorbidities, organ dysfunction, CT findings, peritonitis, treatment methods, and in-hospital mortality among patients was performed.RESULTS: organ dysfunction of ≥ 1 point on the qSOFA scale was detected in 59.0% of the patients. According to CT data, abdominal distant gas was detected in 48 (61.5%) patients, and pericolic gas in 14 (17.9%) patients. Segmental colon resection was performed in 60 (76.9%) patients, laparoscopic lavage (LL) of the abdominal cavity — in 3, non-operative treatment (NOT) with drainage of fluid collections — in 6, and only NOT in 10 patients. Most patients with distant or pericolic gas were operated on within an average time of 1 [0; 3.5] hours after admission. Diffuse peritonitis was detected during surgery in 45 (75%) of them. After resection, organ dysfunction of ≥ 2 points on the SOFA scale developed or progressed in 52 (86.7%) patients. The overall mortality rate was 48.7%, and the postoperative mortality was 63.3%. All patients (n = 38) died after segmental colon resection. Successful NOT was achieved in 4 patients with pericolic gas and 3 patients with distant gas.CONCLUSION: surgery for AICDD in patients with COVID-19 is associated with extremely high mortality, therefore, in the absence of obvious signs of diffuse peritonitis, initial non-operative treatment may be life-saving.

Inpatient treatment of acute diverticulitis between 2010 and 2021 - A German nationwide study about long-term trends and effects of the SARS-CoV-2 pandemic

AIM

The aims of this study were to analyse all hospitalizations for acute diverticulitis in Germany from 2010 to 2021 and to assess the effects of the first 2 years of the SARS-CoV-2 pandemic on hospitalizations for acute diverticulitis.

METHOD

Using data from the German Federal Statistical Office, we analysed fully anonymized healthcare data of hospitalizations and treatment regimens with acute diverticulitis as the main diagnosis between 2010 and 2021. Logistic regression analyses for in-hospital mortality were performed.

RESULTS

A total of 608,162 hospitalizations were included. While the number of hospitalizations constantly increased until 2019 (+52.4%), a relative decrease of 10.1% was observed between 2019 and 2020, followed by stable numbers of hospitalizations in 2021 (+1.1% compared with 2020). In-hospital mortality showed a relative decrease of 33.2% until 2019 and thereafter a relative increase of 26.9% in 2020 and of 7.5% in 2021. A 21.6% and a 19.3% drop in hospitalizations was observed during the first and second waves of the SARS-CoV-2 pandemic, mostly affecting hospitalizations for uncomplicated diverticulitis, with a corresponding 11.6% and 16.8% increase in admissions for complicated diverticulitis. Multivariable logistic regression analyses showed significantly higher in-hospital mortality for hospitalizations in which surgery (OR = 2.76) and CT (OR = 1.32) were given, as well as lower mortality for women (OR = 0.88), whereas percutaneous drainage was not associated with higher in-hospital mortality compared with conservative treatment (OR = 0.71).

CONCLUSION

This study points out the long-term trends in inpatient treatment for acute diverticulitis and the in-hospital mortality risk factors of patients hospitalized for acute diverticulitis in a large nationwide cohort, as well as changes in these trends and factors resulting from the SARS-CoV-2 pandemic. These changes might be attributable to delayed diagnosis and thus more severe stages of disease as a result of containment measures.

Small Bowel Diverticulosis and COVID-19: Awareness Is the Key: A Case Series and Review of the Literature

Small bowel non-Meckelian diverticulosis is a rare condition with only a few published cases despite being described over 200 years ago. In the midst of the COVID-19 pandemic, studies suggested that many patients may experience gastrointestinal manifestations. Intestinal symptoms could worsen the inflammation and infection associated with small bowel diverticulitis. Here we present three cases: one with inflammation and rupture in a COVID-19 patient and another as an asymptomatic detection. The third case involved recurrence after the first laparoscopic lavage approach. Furthermore, we provide a mini-review of the literature to emphasize the importance of considering this entity in the differential diagnosis of an acute abdomen. In the majority of cases involving small bowel diverticula, conservative management is the preferred approach. However, when complications arise, surgical intervention, including enteroctomy and primary anastomosis, may be necessary to achieve optimal outcomes.

Diverticulitis patient care during the Covid-19 pandemic in Germany-a retrospective nationwide population-based cohort study

PURPOSE

Coronavirus disease 2019 (COVID-19) impacted health care systems around the world. Despite a decrease in emergency admissions, an increased number of complicated forms of diverticulitis was reported. It was the aim of this study to analyze the pandemic impact on diverticulitis management in Germany.

METHODS

This is a retrospective population-wide analysis of hospital billing data (2012-2021) of diverticulitis in Germany. Patients were identified based on diagnosis (ICD10) and procedural codes to stratify by conservative and operative management. Primary outcome of interest was admission rates, secondary outcomes were rates of surgical vs conservative treatment and fraction of complicated clinical courses during the pandemic.

RESULTS

Of a total of 991,579 cases, 66,424 (6.7%) were admitted during pandemic lockdowns. Conservative treatment was the most common overall (66.9%) and higher during lockdowns (70.7%). Overall admissions and population adjusted rates of surgically treated patients decreased, the latter by 12.7% and 11.3%, corrected to estimated rates, in the two lockdowns. Surgery after emergency presentation decreased by 7.1% (p=0.053) and 11.1% (p=0.002) in the two lockdowns with a higher rate of ostomy and/or revision (+5.6%, p=0.219, and +10.2%, p=0.030). In-hospital mortality was increased in lockdown periods (1.64% vs 1.49%). In detail, mortality was identical in case of conservative treatment during lockdown periods (0.5%) but was higher in surgically treated patients (4.4% vs 3.6%).

CONCLUSION

During lockdowns, there was an overall decrease of admissions for diverticulitis, especially non-emergency admissions in Germany, and treatment was more likely to be conservative. In case of surgery, however, there was increased risk of a complicated course (ostomy, re-surgery), possibly due to patient selection.

How the COVID-19 pandemic affected the severity and clinical presentation of diverticulitis

BACKGROUND/AIMS

Single-institution studies showed that patients presented with more severe diverticulitis and underwent more emergency operations during the coronavirus disease 2019 (COVID-19) pandemic. Therefore, we studied this trend using nationwide data from the American College of Surgeons National Surgical Quality Improvement Program database.

METHODS

Patients (n = 23,383) who underwent a colectomy for diverticulitis in 2018 (control year) and 2020 (pandemic year) were selected. We compared these groups for differences in disease severity, comorbidities, perioperative factors, and complications.

RESULTS

During the pandemic, colonic operations for diverticulitis decreased by 13.14%, but the rates of emergency operations (17.31% vs. 20.04%, P< 0.001) and cases with a known abscess/perforation (50.11% vs. 54.55%, P< 0.001) increased. Likewise, the prevalence of comorbidities, such as congestive heart failure, acute renal failure, systemic inflammatory response syndrome, and septic shock, were higher during the pandemic (P< 0.05). During this same period, significantly more patients were classified under American Society of Anesthesiologists classes 3, 4, and 5, suggesting their preoperative health states were more severe and life-threatening. Correspondingly, the average operation time was longer (P< 0.001) and complications, such as organ space surgical site infection, wound disruption, pneumonia, acute renal failure, septic shock, and myocardial infarction, increased (P< 0.05) during the pandemic.

CONCLUSIONS

During the pandemic, surgical volume decreased, but the clinical presentation of diverticulitis became more severe. Due to resource reallocation and possibly patient fear of seeking medical attention, diverticulitis was likely underdiagnosed, and cases that would have been elective became emergent. This underscores the importance of monitoring patients at risk for diverticulitis and intervening when criteria for surgery are met.

Impact of the first COVID-19 surge on the outcomes of diverticulitis

Introduction

During the first surge of the COVID-19 pandemic, healthcare utilization changed. We sought to examine the impact of the first COVID-19 surge on the outcomes of patients whose elective surgeries for diverticulitis were postponed and those who underwent urgent surgery during the surge.

Materials and methods

This was a retrospective study from a single tertiary center in the Northeast of the US. Patients whose elective surgeries were delayed, or who underwent urgent surgery for diverticulitis during the first COVID-19 surge (3/16/2020 to 8/1/2020) were included. A cohort from 2019 was used for comparison. Variables were compared between groups including: procedure, death, length of stay, disposition, stoma rate, technique for surgery, and leak rate.

Results

Forty-five patients were included in the COVID-19 group and 44 patients in the 2019 group. Twenty-seven patients had elective surgeries delayed during the COVID-19 surge. Ten (37%) required more urgent surgery, 80% with complicated disease. Six (22%) were admitted to the hospital and 13 (48%) required additional antibiotics. Eight (30%) patients postponed their surgeries indefinitely and 7 (26%) had surgery once permitted. There were no observed differences between the two groups in the rate of complicated disease, leaks, technique for surgery or stoma rate.

Conclusions

During the first COVID-19 surge, over 1/3 of patients whose elective diverticulitis surgeries were postponed required urgent surgery, a majority of whom had complicated disease. There were no apparent differences in outcomes when compared to a pre-pandemic cohort, highlighting the importance of a triage system with the ability to escalate surgery in a timely manner.

Diagnosing Bacterial Infection in the era of Pandemic: A Case Report

In the coronavirus disease 2019 (COVID-19) pandemic era, physicians’ clinical decision-making is often distorted. A man in his 60s presented with an already-subsided cough and anxiety about COVID-19. The physician was influenced by the patient’s anxiety and stuck to exclusion of COVID-19. The patient was finally diagnosed with sepsis caused by obstructive pyelonephritis. The key point for diagnosis was physicians’ awareness that the patient took slow and heavy steps. To confront the challenge of making an appropriate diagnosis of bacterial infection in the era of COVID-19, physicians should be aware of diagnostic biases and watch patients’ general appearance closely.

Does the COVID-19 Pandemic Affect Morbidity and Mortality Rates of Emergency General Surgery? A Retrospective Study from a Single-Center Tertiary Greek Hospital

Background and Objectives: The outbreak of the COVID-19 pandemic had a major impact on all aspects of health care. Few up-to-date studies have actually assessed the impact of COVID-19 on emergency surgeries. The aim of this study was to provide an overview of the impact of the pandemic relating to the emergency surgery performed, as well as morbidity and mortality rates during the first year of the pandemic (March 2020–February 2021) and during the control period. In this period, the first propaedeutic surgery department and the third surgery department of the University General Hospital of Thessaloniki “AHEPA” in Greece provided continuous emergency general surgery services. Material and Methods: The study is in a retrospective cohort and included patients who were admitted to the Emergency Department and underwent emergency general surgery during the control period (n = 456), March 2019–February 2020 and during the first year of the pandemic (n = 223), March 2020–February 2021. Gender, age, type of surgical operation (morbidity), ICU need, the patient’s outcome, and days of hospitalization were compared. Results: A total of 679 emergency surgeries were included. Statistically significant differences emerged between the two time periods in the total number of emergency surgeries performed (p < 0.001). The most common type of surgery in the control period was associated with soft tissue infection while, during the pandemic period, the most common type of surgery was associated with the hepatobiliary system. In addition, the mortality rates nearly doubled during the pandemic period (2.2% vs. 4%). Finally, the mean age of our sample was 50.6 ± 17.5 and the majority of the participants in both time periods were males. Conclusions: The COVID-19 pandemic changed significantly the total number of emergency general surgeries performed. Mortality rates doubled and morbidity rates were affected between the control and pandemic periods. Finally, age, gender, length of hospitalization, intensive care unit hospitalization, and laparoscopy use in patients undergoing emergency surgery during the pandemic were stable.
