ABSTRACT

Background/Aims@#The coronavirus disease 2019 (COVID-19) outbreak caused numerous social and cultural changes, but few studies focused on their effects on gastroenterology (GI) fellowship training. This study evaluated the impact of COVID-19 on GI fellowship training. @*Methods@#A web-based questionnaire was sent out to GI fellows in Korea between 15 February and 15 March 2021. The questionnaire included questions regarding the characteristics of GI fellows, perception of COVID-19 outbreak, impact of COVID-19 outbreak, and telemedicine on the education of a GI fellowship. @*Results@#Among 111 answers, 94 respondents were analyzed. The GI fellows were provided with sufficient information about the COVID-19 outbreak (74.7%), well educated, and provided with personal protective equipment use (74.7% and 83.9%, respectively).On the other hand, outpatient schedule and volume decreased in 25.5% and 37.8% of respondents, respectively. Moreover, endoscopy sessions and volume decreased in 51.1% and 65.6% of respondents, respectively. As a result, 78.9% of respondents were concerned that the COVID-19 outbreak adversely affected their education. Telemedicine utilization was introduced during the COVID-19 outbreak, but only 20.0% and 10.6% of respondents agreed that telemedicine has benefits from the patient’s and doctor’s perspectives, respectively. In addition, only 25.9% of respondents were willing to continue telemedicine if adequately reimbursed, and 68.2% of respondents were concerned that it adversely affected their education. @*Conclusions@#The COVID-19 outbreak has adversely affected GI fellowship training in Korea for outpatient clinics, gastrointestinal endoscopy, educational conferences, and telemedicine. This study highlights that GI fellowship training needs more attention in the COVID-19 outbreak.

ABSTRACT

The area of endoscopic application has been continuously expanded since its introduction in the last century and the frequency of its use also increased stiffly in the last decades. Because gastrointestinal endoscopy is naturally exposed to diseased internal organs and contact with pathogenic materials, endoscopy mediated infection or disease transmission becomes a major concern in this field. Gastrointestinal endoscopy is not for single use and the proper reprocessing process is a critical factor for safe and reliable endoscopy procedures. What needed in these circumstances is a practical guideline for reprocessing the endoscope and its accessories which is feasible in the real clinical field to guarantee acceptable prevention of pathogen transmission. This guideline contains principles and instructions of the reprocessing procedure according to the step by step. And it newly includes general information and updated knowledge about endoscopy-mediated infection and disinfection. Multiple societies and working groups participated to revise; Korean Association for the Study of the Liver, the Korean Society of Infectious Diseases, Korean College of Helicobacter and Upper Gastrointestinal Research, the Korean Society of Gastroenterology, Korean Society of Gastrointestinal Cancer, Korean Association for the Study of Intestinal Diseases, Korean Pancreatobiliary Association, the Korean Society of Gastrointestinal Endoscopy Nurses and Associates and Korean Society of Gastrointestinal Endoscopy. Through this cooperation, we enhanced communication and established a better concordance. We still need more researches in this field and fill up the unproven area. And our guidelines will be renewed accordingly.

ABSTRACT

BACKGROUND/AIMS: Little is known for the capacity and quality of colonoscopy, and adherence to colonoscopy surveillance guidelines in Korea. This study aimed to investigate the present and potential colonoscopic capacity, colonoscopic quality, and adherence to colonoscopy surveillance guidelines in Korea. METHODS: We surveyed representative endoscopists of 72 endoscopy units from June to August 2015, using a 36-item questionnaire regarding colonoscopic capacity, quality, and adherence to colonoscopy surveillance guidelines of each hospitals. RESULTS: Among the 62 respondents who answered the questionnaire, 51 respondents were analyzed after exclusion of 11 incomplete answers. Only 1 of 3 of endoscopy units can afford to perform additional colonoscopies in addition to current practice, and the potential maximum number of colonoscopies per week was only 42. The quality of colonoscopy was variable as reporting of quality indicators of colonoscopy were considerably variable (29.4%–94.1%) between endoscopy units. Furthermore, there are substantial gaps in the adherence to colonoscopy surveillance guidelines, as concordance rate for guideline recommendation was less than 50% in most scenarios. CONCLUSIONS: The potential capacity and quality of colonoscopy in Korea was suboptimal. Considering suboptimal reporting of colonoscopic quality indicators and low adherence rate for colonoscopy surveillance guidelines, quality improvement of colonoscopy should be underlined in Korea.

ABSTRACT

BACKGROUND/AIMS: Knowledge regarding the quality metrics of fecal immunochemical test (FIT)-based colorectal cancer screening programs is limited. The aim of this study was to investigate the performance and quality metrics of a FIT-based screening program. METHODS: In our screening program, asymptomatic subjects aged ≥50 years underwent an annual FIT, and subjects with positive FIT results underwent a subsequent colonoscopy. The performance of the FIT and colonoscopy was analyzed in individuals with a positive FIT who completed the program between 2009 and 2015 at a university hospital. RESULTS: Among the 51,439 screened participants, 75.1% completed the FIT. The positive rate was 1.1%, and the colonoscopy completion rate in these patients was 68.6%. The positive predictive values of cancer and advanced neoplasia were 5.5% and 19.1%, respectively. The adenoma detection rate in the patients who underwent colonoscopy after a positive FIT was 48.2% (60.0% for men and 33.6% for women). The group with the highest tertile quantitative FIT level showed a significantly higher detection rate of advanced neoplasia than the group with the lowest tertile (odds ratio, 2.6; 95% confidence interval, 1.4 to 5.1; p < 0.001). CONCLUSIONS: The quality metrics used in the United States and Europe may be directly introduced to other countries, including Korea. However, the optimal quality metrics should be established in each country.

ABSTRACT

BACKGROUND/AIMS: There is substantial evidence supporting a role of inflammation in the pathogenesis of colorectal cancer; however, little is known about the association between serum C-reactive protein (CRP) and the risk of colorectal adenoma. This study was conducted to investigate the association between serum CRP and colorectal adenoma risk. METHODS: A retrospective cross-sectional study was performed on first-time screening colonoscopies in asymptomatic subjects who also had their serum CRP level measured during a routine health check-up between September 2006 and September 2009 in Korea. Serum CRP level was compared between high-risk and low-risk adenoma groups and independent predictors of high-risk adenoma were analyzed using multivariate regression analysis. RESULTS: Among the 3,309 eligible patients, the high-risk adenoma group had higher serum CRP levels than the low-risk adenoma group (P=0.000). In addition, patients with a high-risk adenoma were more frequently included in the high CRP group than in the low CRP group (8.6% vs. 4.0%, P<0.001). The prevalence of high-risk adenoma was 3.5 times higher in the highest quartile of CRP level (P=0.000) compared with that in the lowest quartile. In logistic regression analysis, a higher quartile CRP level was found to be an independent risk factor for high-risk adenoma (odds ratio, 1.8; 95% confidence interval, 1.3–2.5; P=0.000). CONCLUSIONS: High CRP level is associated with high-risk adenoma in both men and women. Our data may support the association between chronic inflammation and colorectal neoplasia, which warrants further investigation.

ABSTRACT

BACKGROUND/AIMS: Treatment of chronic hepatitis C virus (HCV) infection in patients with chronic kidney disease (CKD) is essential. The availability of sofosbuvir (SOF) has dramatically improved overall HCV cure rates, however there is insufficient data regarding its use in patients with CKD. We evaluated SOF in patients with hepatitis C genotype 1 (G1) and moderately impaired renal function. METHODS: We retrospectively reviewed all patients treated with a SOF-based regimen from December 2013 through September 2015 at Virginia Mason Medical Center. Data was then collected for HCV G1 patients with stage 3 CKD. RESULTS: A total of 28 patients with HCV G1 and stage 3 CKD were treated with a SOF-based regimen. Twenty-one patients had stage 3A CKD (estimated glomerular filtration rate [eGFR] 45–60 mL/min/1.73m2) and 7 patients had stage 3B CKD (eGFR 30–45 mL/min/1.73m2). The overall rate of sustained virologic response (SVR) 12 weeks after completion of therapy (SVR12) was 85.7% (24/28). SVR12 in stage 3A CKD patients was 81.0% (17/21) and in stage 3B CKD patients, SVR12 was 100% (7/7). Based on the treatment regimen used, the SVR12 was 81.8% (9/11), 92.3% (12/13), and 75.0% (3/4) for SOF/ledipasvir (LDV), SOF/simeprevir (SIM), and SOF/pegylated interferon (PEG)/ribavirin (RBV), respectively. Greater than 30% reduction eGFR was observed in 4 out of 28 patients. CONCLUSIONS: SOF-based regimens resulted in high SVR12 rates in patients with moderately impaired renal function. During therapy, HCV patients with CKD should be carefully monitored for worsening renal function.

ABSTRACT

BACKGROUND/AIMS: The approval of sofosbuvir (SOF), a direct-acting antiviral, has revolutionized the treatment of chronic hepatitis C virus (HCV). METHODS: We assessed the sustained virological response (SVR) of SOF-based regimens in a real-world single-center setting for the treatment of chronic HCV genotype 1 (G1) patients. This was a retrospective review of chronic HCV G1 adult patients treated with a SOF-based regimen at Virginia Mason Medical Center between December 2013 and August 2015. RESULTS: The cohort comprised 343 patients. Patients received SOF+ledipasvir (LDV) (n=155), SOF+simeprevir (SIM) (n=154), or SOF+peginterferon (PEG)+ribavirin (RBV) (n=34). Of the patients, 50.1% (n=172) had cirrhosis. The SVR rate was 92.2% for SOF/LDV, 87.0% for SOF/SIM, and 82.4% for SOF/PEG/RBV. Compared with the cirrhotic patients, the patients without cirrhosis had a higher SVR (96.8% vs 85.5%, p=0.01, SOF/LDV; 98.2% vs 80.6%, p=0.002, SOF/SIM; 86.4% vs 75.0%, p=0.41, SOF/PEG/RBV). In this study, prior treatment experience adversely affected the response rate in subjects treated with SOF/PEG/RBV. CONCLUSIONS: In this single-center, real-world setting, the treatment of chronic HCV G1 resulted in a high rate of SVR, especially in patients without cirrhosis.

ABSTRACT

Small bowel obstruction is a clinical condition commonly caused by postoperative adhesion, volvulus, intussusceptions, and hernia. Small bowel obstruction due to bezoars is clinically uncommon, accounting for approximately 2-4% of all obstructions. Computed tomography (CT) is a useful method in diagnosing the cause of small bowel obstruction. However, small bowel obstruction caused by bezoars may not be detected by an abdominal CT examination. Herein, we report a rare case of small bowel obstruction by Aloe vera bezoars, which were undetected by an abdominal CT. Phytobezoars should be included in the differential diagnosis of small bowel obstruction in patients with predisposing factors, such as excessive consumption of high-fiber food and diabetes.

ABSTRACT

With an increased use of the press-through package (PTP) tablet, there has also been an increase in mis-swallowing cases, especially in elderly patients. We report a rare case of PTP-induced small bowel perforation and fistula formation with adjacent small bowel in a healthy elderly patient, who experienced persistent abdominal pain of unknown cause. A 62-year-old healthy man was admitted to our hospital with left abdominal pain that started one month ago. Neither abdominal tenderness nor rebound tenderness was present on physical examination. His vital signs and all other test results were within normal limits. However, a 2.5 cm curved radiopaque material within his thickened small intestine was incidentally detected on an abdominal computed tomography. He underwent laparoscopic small bowel resection, which revealed foreign body in the distal small intestine. Edema, perforation, and adhesions with the surrounding tissues were also noticed in the distal small intestine. Foreign body was turned out to be PTP, and this was considered to be responsible for the small bowel perforation and fistula formation. Precautions regarding PTP usage are necessary to prevent inadvertent PTP ingestion and its related complications, such as perforation, especially in the elderly population.

ABSTRACT

BACKGROUND/AIMS: Western surveillance strategies cannot be directly adapted to the Korean population. The aim of this study was to estimate the risk of metachronous neoplasia and the optimal surveillance interval in the Korean population. METHODS: Clinical and pathological data from index colonoscopy performed between June 2006 and July 2008 and who had surveillance colonoscopies up to May 2015 were compared between low- and high-risk adenoma (LRA and HRA) groups. The 3- and 5-year cumulative risk of metachronous colorectal neoplasia in both groups were compared. RESULTS: Among 895 eligible patients, surveillance colonoscopy was performed in 399 (44.6%). Most (83.3%) patients with LRA had a surveillance colonoscopy within 5 years and 70.2% of patients with HRA had a surveillance colonoscopy within 3 years. The cumulative risk of metachronous advanced adenoma was 3.2% within 5 years in the LRA group and only 1.7% within 3 years in the HRA group. The risk of metachronous neoplasia was similar between the surveillance interval of <5 and ≥5 years in the LRA group; however, it was slightly higher at surveillance interval of ≥3 than <3 years in the HRA group (9.4% vs. 2.4%). In multivariate analysis, age and the ≥3-year surveillance interval were significant independent risk factors for metachronous advanced adenoma (P=0.024 and P=0.030, respectively). CONCLUSIONS: Patients had a surveillance colonoscopy before the recommended guidelines despite a low risk of metachronous neoplasia. However, the risk of metachronous advanced adenoma was increased in elderly patients and those with a ≥3-year surveillance interval.

ABSTRACT

Patients with inflammatory bowel disease (IBD) have an elevated risk of venous thromboembolism compared with the general population. The most common sites of venous thromboembolism in IBD patients are the deep veins of the legs, the pulmonary system, and portal and mesenteric veins. However, cerebral venous thrombosis is rarely associated with IBD. This report describes a case of cerebral venous thrombosis in a patient with Crohn's disease. A 17-year-old girl, diagnosed 4 years earlier with Crohn's disease, presented with headache and vomiting. Magnetic resonance imaging of the brain with venography showed venous thrombosis in the cortical veins, superior sagittal sinus, right transverse sinus, and right internal jugular vein. The patient immediately started anticoagulation therapy with intravenous heparin infusion followed by daily oral rivaroxaban 10 mg. Follow-up imaging after 2 weeks showed resolution of the thrombosis, with recanalization of the cortical veins, superior sagittal sinus, right transverse sinus, and right internal jugular vein. She continued rivaroxaban therapy for 6 months, and remained well, without neurologic sequelae. A high level of concern for cerebral venous thrombosis may be important when treating active IBD patients, because anticoagulation treatment can prevent fatal complications.

ABSTRACT

The incidence of lower gastrointestinal bleeding (LGIB) is increasing; however, predictors of outcomes for patients with LGIB are not as well defined as those for patients with upper gastrointestinal bleeding (UGIB). The aim of this study was to identify the clinical outcomes and the predictors of poor outcomes for patients with LGIB, compared to outcomes for patients with UGIB. We identified patients with LGIB or UGIB who underwent endoscopic procedures between July 2006 and February 2013. Propensity score matching was used to improve comparability between LGIB and UGIB groups. The clinical outcomes and predictors of 30-day rebleeding and mortality rate were analyzed between the two groups. In total, 601 patients with UGIB (n = 500) or LGIB (n = 101) were included in the study, and 202 patients with UGIB and 101 patients with LGIB were analyzed after 2:1 propensity score matching. The 30-day rebleeding and mortality rates were 9.9% and 4.5% for the UGIB group, and 16.8% and 5.0% for LGIB group, respectively. After logistic regression analysis, the Rockall score (P = 0.013) and C-reactive protein (CRP; P = 0.047) levels were significant predictors of 30-day mortality in patients with LGIB; however, we could not identify any predictors of rebleeding in patients with LGIB. The clinical outcomes for patients with LGIB are not better than clinical outcomes for patients with UGIB. The clinical Rockall score and serum CRP levels may be used to predict 30-day mortality in patients with LGIB.

ABSTRACT

Vasculopathy is rarely reported in neurofibromatosis type 1, but when it occurs it primarily involves the aorta and its main branches. Among vasculopathies, aneurysmal dilatation is the most common form. Although several case reports concerning aneurysms or pseudoaneurysms of visceral arteries in neurofibromatosis type 1 patients have been reported, there are no reports describing gastroduodenal artery aneurysms associated with neurofibromatosis type 1. We experienced a case of life-threatening duodenal ulcer bleeding from a ruptured gastroduodenal artery aneurysm associated with neurofibromatosis type 1. We treated our patient by transarterial embolization after initial endoscopic hemostasis. To our knowledge, this is the first reported case of its type. High levels of suspicion and prompt diagnosis are required to select appropriate treatment options for patients with neurofibromatosis type 1 experiencing upper gastrointestinal bleeding. Embolization of the involved arteries should be considered an essential treatment over endoscopic hemostasis alone to achieve complete hemostasis and to prevent rebleeding.

ABSTRACT

Lymphangioma is a benign vascular lesion with characteristics of subepithelial tumor which can proliferate in the lymphatic system. Lymphangioma of the small-bowel mesentery is rare, having been reported in less than 2% of all lymphangiomas. Lymphangioma does not require any specific treatment because it is absolutely a benign tumor. However, surgical exploration is rarely required for cases with disease-related symptoms or complications, or for those misdiagnosed as a malignant lesion. We recently experienced a case of mesenteric cavernous lymphangomas in a 53-year-old female who was misdiagnosed as having a liposarcoma. The final diagnosis was confirmed by a pathologic examination of the specimen that was obtained via laparoscopic exploration. Herein, we report a very rare case of mesenteric cavernous lymphangioma along with a brief review of relevant literature.

ABSTRACT

Colonoscopy is the current standard method for evaluation of the colon. The diagnostic accuracy and therapeutic safety of colonoscopy depend on the quality of colonic cleansing and preparation. Generally, all these preparations have been demonstrated to be safe for use in healthy individuals without significant comorbid conditions. Based on safety and efficacy concerns, polyethylene glycol (PEG) is most commonly utilized as a bowel preparation solution for colonoscopy. Adverse events in patients receiving PEG are mostly clinically non-significant. However, fatal adverse events rarely have been shown to occur in the few individuals who experience vomiting or aspiration. Anaphylactic shock associated with ingestion of PEG electrolyte solution is an extremely rare fatal complication, and reported mainly in Western countries. Here, we report the first case of anaphylactic shock following the ingestion of PEG solution in Korea.

ABSTRACT

Primary duodenal carcinoma is rare. Duodenal mucinous adenocarcinoma (DMA) is even rarer, and its associated manifestations and typical endoscopic or imaging findings are not well characterized. Herein, we report a case of primary DMA in an asymptomatic 58-year-old man who visited our hospital for a regular health screening. Upper endoscopy revealed an approximately 4-cm lesion in the second portion of the duodenum, but the mass was not visualized on computed tomography. Biopsies revealed a tubular adenoma that was subsequently resected. Frozen biopsies demonstrated DMA with a background of low-grade tubular adenoma for which we performed Roux-en-Y duodenojejunostomy and jejunojejunostomy. To our knowledge, this is the first report of a patient with DMA in Korea.

ABSTRACT

We report a case of patient with acute toxic hepatitis induced by weight-loss herbal supplement. A patient took natural extract supplement containing Garcinia cambogia for only two days and visited Kyung Hee University Hospital at Gangdong complaining of abdominal discomfort and jaundice. Serum ceruloplasmin level was decreased and hepatic copper levels on liver biopsy specimen were increased. Although, those were mimicking Wilson's disease, pathological findings and clinical manifestations were consistent with drug-induced acute hepatitis. Genetic test was negative for Wilson's disease. After one month of hospitalization, the patient improved and was discharged home in good condition. She was followed up for four months and her symptoms and signs of hepatitis continued to improve steadily with normal liver function tests. Our case emphasizes the importance of taking a caution when taking herbal supplements for the purpose of weight loss. This case also demonstrates the importance of suspicion of medication-related adverse events, even though the duration of taking the materials seems to be too short to affect the patients.

ABSTRACT

BACKGROUND/AIMS: 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.

ABSTRACT

BACKGROUND/AIMS: Several factors affecting the severity and outcomes of diverticulitis have been reported, but there is little research on physician specialty related with this disease. Therefore, we evaluated the clinical characteristics and outcomes of diverticulitis depending on physician's specialty. METHODS: Medical records of 239 patients, who had been hospitalized with first-diagnosed acute colonic diverticulitis at Kyung Hee University Hospital in Gang Dong (Seoul, Korea) from June 2006 to December 2012, were retrospectively analyzed. The patients were classified according to whether they had been managed by gastroenterologists or not. Clinical characteristics and treatment outcomes were compared between two groups. RESULTS: Of these 239 patients, 38 (15.9%) patients were treated by a gastroenterologist and 201 (84.1%) patients by a non-gastroenterologist. Clinical characteristics such as age, gender, body mass index, comorbidity, medication, laboratory results, recurrence and complication were not significantly different between two groups. However, right-sided diverticulitis predominated in the non-gastroenterologist group (79% vs. 91%, P=0.028). From the sub-group analysis of uncomplicated diverticulitis, intravenous antibiotics was used for a shorter period of time by gastroenterologists than non-gastroenterologists (3.3+/-1.9 days vs. 4.4+/-2.8 days, P=0.032). Multivariate logistic regression analysis showed that the 3 day administration of intravenous antibiotics significantly depended on the physician's specialty (odds ratio 7.984, 95% confidence interval 1.990-32.043, P=0.003).
