Background/Aims
Despite of the coronavirus disease 2019 (COVID-19) pandemic, there is little data regarding its impact on colorectal cancer (CRC)-related clinical practice. This study aimed to assess the changes in its impact during the COVID-19 pandemic.
Methods
This was a retrospective national population-based study using the Health Insurance Review and Assessment database from January 2019 to December 2021. The number of patients in 2020 and 2021 was compared with those in 2019 for the diagnostic and therapeutic colonoscopy, CRC-related operation, and any treatment for CRC.
Results
The annual number of patients undergoing diagnostic colonoscopies decreased by 6.9% in 2020 but increased 8.1% in 2021, compared to those in 2019; number of patients undergoing therapeutic colonoscopies increased by 6.0% and 37.7% in 2020 and 2021, respectively; number of patients operated for CRC decreased by 4.2% in 2020 and increased by 2.3% in 2021. The number of patients treated for CRC decreased by 2.8% in 2020 and increased by 4.4% in 2021. Diagnostic and therapeutic colonoscopies and any CRC-related treatment decreased by 43.8%, 37.5%, and 11.3% in March 2020, during the first surge of COVID-19, but increased by 26.0%, 58.1%, and 9.5% in June 2021, respectively. CRC-related operations decreased by 24.1% in April 2020 and increased by 12.6% in August 2021.
Conclusions
Negative impact of the COVID-19 pandemic on clinical practices related to CRC completely recovered within second year. It could be considered for the development of an optimal strategy on CRC management in response to the pandemic-driven crisis.

Colorectal neoplasia

The elderly population are more vulnerable for the management of colorectal cancer during the COVID-19 pandemic: a nationwide, population-based study: Hong Sun Kang, Seung Hoon Jeon, Su Bee Park, Jin Young Youn, Min Seob Kwak, Jae Myung Cha; Intest Res 2023;21(4):500-509.

Background/Aims
The impact of coronavirus disease 2019 (COVID-19) on the management of colorectal cancer (CRC) may worse in elderly population, as almost all COVID-19 deaths occurred in the elderly patients. This study aimed to evaluate the impact of COVID-19 on CRC management in the elderly population.
Methods
The numbers of patients who underwent colonoscopy, who visited hospitals or operated for CRC in 2020 and 2021 (COVID-19 era) were compared with those in 2019, according to 3 age groups (≥70 years, 50–69 years, and ≤49 years), based on the nationwide, population-based database (2019–2021) in South Korea.
Results
The annual volumes of colonoscopy and hospital visits for CRC in 2020 were more significantly declined in the old age group than in the young age group (both P<0.001). In addition, the annual volume of patients operated for CRC numerically more declined in old age group than in young age group. During the first surge of COVID-19 (March and April 2020), old age patients showed statistically significant declines for the monthly number of colonoscopies (–46.5% vs. –39.3%, P<0.001), hospital visits (–15.4% vs. –7.9%, P<0.001), CRC operations (–33.8% vs. –0.7%, P<0.05), and colonoscopic polypectomies (–41.8% vs. –38.0%, P<0.001) than young age patients, compared with those of same months in 2019.
Conclusions
Elderly population are more vulnerable for the management of CRC during the COVID-19 pandemic. Therefore, the elderly population are more carefully cared for in the management of CRC during the next pandemic.

Association of Gallbladder Polyp with the Risk of Colorectal Adenoma: Jung Won Jeun, Jae Myung Cha, Joung Il Lee, Kwang Ro Joo, Hyun Phil Shin, Jun Uk Lim; Intest Res 2014;12(1):48-52. Published online January 28, 2014; DOI: https://doi.org/10.5217/ir.2014.12.1.48

<b>Background/Aims</b><br/>

Gallbladder polyps and colorectal adenomas share many common risk factors; however, their association has never been studied. The aim of this study was to investigate this association in asymptomatic healthy subjects.

Methods

Consecutive asymptomatic subjects who underwent both screening colonoscopy and abdominal ultrasonography at Kyung Hee University Hospital in Gang Dong between July 2010 and April 2011 were prospectively enrolled. The prevalence of colorectal adenoma was compared between subjects with or without gallbladder polyps. Furthermore, a logistic regression analysis was performed to determine the independent risk factors for colorectal adenoma in these subjects.

Results

Of the 581 participants, 55 presented with gallbladder polyps and 526 did not have gallbladder polyps. Participants with gallbladder polyps showed a trend toward a higher prevalence of colorectal adenoma than those without gallbladder polyps (52.7% vs. 39.2%, P=0.051). Although the result was not statistically significant, gallbladder polyps were found to be a possible risk factor for colorectal adenoma (odds ratio=1.796, 95% confidence interval=0.986-3.269, P=0.055), even after adjusting for potential confounding factors. There was no difference observed in colorectal adenoma characteristics between the two groups.

Conclusions

Our results suggest a possible association between gallbladder polyps and colorectal adenomas. Future studies with larger cohorts are warranted to further investigate this matter.
