What paradigm shifts occurred in the management of acute diverticulitis during the COVID-19 pandemic? A scoping review

Impact of the first wave of COVID-19 epidemy on the surgical management of sigmoid diverticular disease in France: National French retrospective study

OBJECTIVE

To analyze the surgical management of sigmoid diverticular disease (SDD) before, during, and after the first containment rules (CR) for the first wave of COVID-19.

METHODS

From the French Surgical Association multicenter series, this study included all patients operated on between January 2018 and September 2021. Three groups were compared: A (before CR period: 01/01/18-03/16/20), B (CR period: 03/17/20-05/03/20), and C (post CR period: 05/04/20-09/30/21).

RESULTS

A total of 1965 patients (A n = 1517, B n = 52, C n = 396) were included. The A group had significantly more previous SDD compared to the two other groups (p = 0.007), especially complicated (p = 0.0004). The rate of peritonitis was significantly higher in the B (46.1%) and C (38.4%) groups compared to the A group (31.7%) (p = 0.034 and p = 0.014). As regards surgical treatment, Hartmann's procedure was more often performed in the B group (44.2%, vs A 25.5% and C 26.8%, p = 0.01). Mortality at 90 days was significantly higher in the B group (9.6%, vs A 4% and C 6.3%, p = 0.034). This difference was also significant between the A and B groups (p = 0.048), as well as between the A and C groups (p = 0.05). There was no significant difference between the three groups in terms of postoperative morbidity.

CONCLUSION

This study shows that the management of SDD was impacted by COVID-19 at CR, but also after and until September 2021, both on the initial clinical presentation and on postoperative mortality.

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.

The Consequences of COVID-19 Disruption on Sustainable Economy in the Top 30 High-Tech Innovative Countries

This study aims to investigate the effects of the COVID-19 pandemic on the innovation index, Gross Domestic Product (GDP), high technology exports, and human development (HDI) in the world's leading 30 high-tech innovative countries. Using grey relational analysis models, the association between COVID-19 and other economic development indices was investigated. The model selects the country least affected by the pandemic from the top 30 innovative countries through a conservative (maximin) method based on grey association values. Data was collected from World Bank databases and analyzed to compare pre- and post-COVID-19 periods (2019, 2020). The outcomes of this study provide essential recommendations for industries and decision-makers with suitable action plans to preserve economic systems from further harm caused by the global COVID-19 outbreak. The ultimate goal is to boost the innovation index, GDP, high-tech exports, and HDI of high-tech economies and pave the way for a sustainable economy. To the author's knowledge, this is the first study to develop a multidimensional framework to assess COVID-19's impact on the sustainable economy of top 30 high-tech innovative countries, and to conduct a comparative analysis to identify the strong and weak effects of COVID-19 on sustainable economic growth.
