Value of Fecal Calprotectin Measurement During the Initial Period of Therapeutic Anti-Tubercular Trial: Hyeong Ho Jo, Eun Young Kim, Jin Tae Jung, Joong Goo Kwon, Eun Soo Kim, Hyun Seok Lee, Yoo Jin Lee, Kyeong Ok Kim, Byung Ik Jang, the Crohn’s and Colitis Association in Daegu-Gyeongbuk; Clin Endosc 2022;55(2):256-262. Published online November 5, 2021; DOI: https://doi.org/10.5946/ce.2021.061

Background
/Aims: The diagnosis of intestinal tuberculosis (ITB) is often challenging. Therapeutic anti-tubercular trial (TATT) is sometimes used for the diagnosis of ITB. We aimed to evaluate the changing pattern of fecal calprotectin (FC) levels during TATT in patients with ITB.
Methods
A retrospective review was performed on the data of 39 patients who underwent TATT between September 2015 and November 2018 in five university hospitals in Daegu, South Korea. The analysis was performed for 33 patients with serial FC measurement reports.
Results
The mean age of the participants was 48.8 years. The final diagnosis of ITB was confirmed in 30 patients based on complete mucosal healing on follow-up colonoscopy performed after 2 months of TATT. Before starting TATT, the mean FC level of the ITB patients was 170.2 μg/g (range, 11.5-646.5). It dropped to 25.4 μg/g (range, 11.5-75.3) and then 23.3 μg/g (range, 11.5-172.2) after one and two months of TATT, respectively. The difference in mean FC before and one month after TATT was statistically significant (p<0.001), and FC levels decreased to below 100 μg/g in all patients after one month of TATT.
Conclusions
All ITB patients showed FC decline after only 1 month of TATT, and this finding correlated with complete mucosal healing in the follow-up colonoscopy after 2 months of TATT.

Background
/Aims: Capsule endoscopy (CE) is recommended as the primary method for the evaluation of unexplained anemia. This study aimed to assess the diagnostic yield of CE in patients with unexplained iron deficiency anemia (IDA) without overt bleeding, and to evaluate their long-term outcomes and related clinical factors.
Methods
Data of patients who underwent CE for the evaluation of IDA were reviewed from a CE registry in Korea. Additional clinical data were collected by the involved investigators of each hospital through a review of medical records.
Results
Among a total of 144 patients, the diagnostic yield of CE was 34%. Gastrointestinal (GI) bleeding was found in 6.3% (n=9) of the patients (occult bleeding in four patients and overt bleeding in five patients) during a mean follow-up of 17.8 months. Patients with a positive fecal occult blood test (FOBT) result at the initial diagnosis had a higher rate of GI bleeding after CE (p=0.004). In addition, a positive FOBT result was the only independent predictive factor for GI bleeding (hazard ratio, 5.30; 95% confidence interval, 1.41–19.85; p=0.013).
Conclusions
Positive FOBT is a predictive factor for GI bleeding during follow-up after CE in patients with unexplained IDA without overt bleeding. Thus, patients with positive FOBT need to be more closely followed up.

Focused Review Series: Updates on Capsule Endoscopy from Esophagus to Colon

Evaluation of Gastric Disease with Capsule Endoscopy: Seung-Joo Nam, Hyun Seok Lee, Yun Jeong Lim; Clin Endosc 2018;51(4):323-328. Published online July 31, 2018; DOI: https://doi.org/10.5946/ce.2018.092

Abstract PDF PubReader ePub

The clinical indication for capsule endoscopy has expanded from small bowel evaluation to include esophagus or colon evaluation.Nevertheless, the role of capsule endoscopy in evaluation of the stomach is very limited because of the large volume and surface.However, efforts to develop an active locomotion system for capsule manipulation in detailed gastric evaluation are ongoing, becausethe technique is non-invasive, convenient, and safe, and requires no sedation. Studies have successfully reported gastric evaluation usinga magnetic-controlled capsule endoscopy system. Advances in technology suggest that capsule endoscopy will have a major role notonly in the evaluation of gastric disorders but also in the pathologic diagnosis, intervention, and treatment of any gastrointestinal tractdisorder.

Case Report

Primary Colonic Follicular Lymphoma Presenting as Four Diminutive Sessile Polyps Found Incidentally During Colonoscopy: Sun Jin, Hyun Seok Lee, Ji Yun Jeong, Young Wook Jo; Clin Endosc 2018;51(4):388-392. Published online April 18, 2018; DOI: https://doi.org/10.5946/ce.2017.114

Abstract PDF PubReader ePub

Follicular lymphomas, which typically arise in the lymph nodes with spleen, liver, and bone marrow involvement, have generally low occurrence rates in Asian countries as compared with Western countries. Follicular lymphomas of the gastrointestinal tract are rare, and primary colonic follicular lymphomas are particularly rare compared with others found in the small intestine and duodenum. Colonoscopic imaging of colonic lymphomas, including follicular lymphoma, may reveal mucosal ulcerations, erosions, indurations, polypoid mass-like lesions, and diffuse mucosal nodularity. Herein, we report a unique case of a follicular lymphoma of the transverse colon characterized by four sessile diminutive polyps located intermittently with multiple lymph node involvement in a 62-year-old man.

Abstract PDF Supplementary Material PubReader ePub

Capsule endoscopy (CE) enables evaluation of the entire mucosal surface of the small bowel (SB), which is one of the most important steps for evaluating obscure gastrointestinal bleeding. Although the diagnostic yield of SB CE depends on many clinical factors, there are no reports on quality indicators. Thus, the Korean Gut Image Study Group (KGISG) publishes an article titled, “Quality Indicators for Small Bowel Capsule Endoscopy” under approval from the Korean Society of Gastrointestinal Endoscopy (KSGE). Herein, we initially identified process quality indicators, while the structural and outcome indicators are reserved until sufficient clinical data are accumulated. We believe that outcomes of SB CE can be improved by trying to meet our proposed quality indicators.

Case Report

Megaduodenum with Duodenal Diospyrobezoars: Hyun Woo Park, Hyun Seok Lee; Clin Endosc 2015;48(5):436-439. Published online September 30, 2015; DOI: https://doi.org/10.5946/ce.2015.48.5.436

Abstract PDF PubReader ePub

Bezoars are retained masses of ingested materials accumulating within the gastrointestinal track. While gastric bezoars are often observed, duodenal bezoars are rarely reported. A 77-year-old man who had frequently consumed persimmons and had never undergone gastric surgery had symptoms of epigastric pain and early satiety for 10 days. Esophagogastroduodenoscopy showed many diospyrobezoars in a severely distended duodenal bulb, otherwise known as megaduodenum. The patient's treatment consisted of repeated endoscopic removal of the bezoars by using a retrieval net.

Clinical Outcomes of Argon Plasma Coagulation Therapy for Early Gastric Neoplasms: Kyu Young Kim, Seong Woo Jeon, Hea Min Yang, Yu Rim Lee, Eun Jeong Kang, Hyun Seok Lee, Sung Kook Kim; Clin Endosc 2015;48(2):147-151. Published online March 27, 2015; DOI: https://doi.org/10.5946/ce.2015.48.2.147

Abstract PDF PubReader ePub

Background/Aims

Argon plasma coagulation (APC) has some merits in the treatment of gastric neoplasms including a shorter operative time and fewer complications compared with endoscopic mucosal resection or endoscopic submucosal dissection. However, there are few reports on the outcomes of gastric neoplasms treated using APC. The aim of this study was to evaluate APC in the treatment of early gastric neoplasms in terms of clinical efficacy, safety, and local recurrence.

Methods

We enrolled 28 patients who received APC therapy at the Kyungpook National University Hospital between May 2007 and April 2013. Clinical outcomes were analyzed.

Results

The median follow-up period was 24.8 months (range, 2 to 78). Among the 28 lesions treated using the APC procedure, tumor recurrence was encountered in seven lesions (25.0%). Recurrence was found in 50% (5/10) of single APC cases and 11% (2/18) of rescue APC cases. The mean time to recurrence was 16.1 months (range, 2 to 78). There were no serious APC-related complications such as perforation, bleeding, or infection.

Conclusions

APC therapy can be a useful treatment with a favorable safety profile for patients with early gastric neoplasms. However, further studies are necessary to determine the long-term prognosis of patients undergoing this treatment.

Barrett Esophagus in Asia: Same Disease with Different Pattern: Hyun Seok Lee, Seong Woo Jeon; Clin Endosc 2014;47(1):15-22. Published online January 24, 2014; DOI: https://doi.org/10.5946/ce.2014.47.1.15

Abstract PDF PubReader ePub

Barrett esophagus (BE) is considered to develop as a result of chronic gastroesophageal reflux disease (GERD) and to predispose to esophageal adenocarcinoma (EAC). However, the disease pattern of BE in Asia differs from that observed in the West. For example, in the West, the prevalence rates of BE and EAC have progressively increased, whereas although the prevalence rate of GERD is increasing in Asia, the prevalence rates of BE and EAC have remained low in most Asian countries. GERD, hiatal hernia, old age, male sex, abdominal obesity (visceral obesity), smoking, alcohol consumption, and kyphosis are known risk factors for BE in Asia, and most Asian patients have short-segment BE. Helicobacter pylori infection is more prevalent in Asia than in the West. We suggest larger studies with a prospective design be conducted to elaborate further the different patterns of BE in Asia.
