Abstract PDF PubReader ePub: Background
/Aims: Few studies have compared the performances of endoscopic knives. This study aimed to compare the therapeutic outcomes of a novel core knife and the conventional IT knife 2 for endoscopic submucosal dissection (ESD) of gastric mucosal lesions.
Methods
This prospective, non-inferiority trial included patients diagnosed with gastric adenoma or early-stage adenocarcinoma at Keimyung University Dongsan Hospital between June and November 2020. The patients were randomly assigned to either the core knife or the IT knife 2 group. The operators and assistants scored the knives’ grip convenience and cutting abilities.
Results
A total of 39 patients were enrolled (core knife group, 20 patients; IT knife 2 group, 19 patients). There were no significant between-group differences in operator-assessed grip convenience (9.600 vs. 9.526, p=0.753), cutting ability (9.600 vs. 9.105, p=0.158), or assistant-assessed grip convenience (9.500 vs. 9.368, p=0.574).
Conclusions
The core knife achieved therapeutic outcomes that were comparable to those of the IT knife 2 for ESD of gastric mucosal lesions.

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.

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.

Special Review: Korean Society of Gastrointestinal Endoscopy “Accreditation of Qualified Endoscopy Unit” Guideline: Update 2019

Updates on the Sedation for Gastrointestinal Endoscopy: Jun Kyu Lee, Yoo Jin Lee, Jun Hyung Cho, Jong Pil Im, Chang-Hwan Park, Jae-Young Jang, Byung Ik Jang, the Quality Management Committee and the Disinfection Management/Conscious Sedation Committee of Korean Society of Gastrointestinal Endoscopy (KSGE); Clin Endosc 2019;52(5):451-457. Published online September 30, 2019; DOI: https://doi.org/10.5946/ce.2019.172

Abstract PDF Supplementary Material PubReader ePub

Sedation, defined as the depressed level of consciousness, induced by drug administration, is widely used for gastrointestinal endoscopy to relieve a patient’s anxiety and discomfort. In addition, successful procedure is anticipated with control of unintended movements. Endoscopic sedation, however, cannot be free from the risk of serious adverse events, e.g., cardiopulmonary compromise. Therefore, principles on personnel, facility and equipment, as well as performance itself, should be followed to prevent unfavorable incidents. In this article, sedation guidelines for the Accreditation of Qualified Endoscopy Units, issued by the Korean Society of Gastrointestinal Endoscopy, are presented.

Characteristics of Synchronous and Metachronous Multiple Gastric Tumors after Endoscopic Submucosal Dissection of Early Gastric Neoplasm: Hyun Jik Lee, Yoo Jin Lee, Ju Yup Lee, Eun Soo Kim, Woo Jin Chung, Byoung Kuk Jang, Kyung Sik Park, Jae Seok Hwang, Kwang Bum Cho; Clin Endosc 2018;51(3):266-273.

Background
/Aims: Endoscopic submucosal dissection (ESD) has been widely accepted as a method of treatment of early gastric tumor. This study aimed to identify the incidence and characteristics of multiple gastric tumors after ESD.
Methods
Patients with early gastric tumors who were treated by ESD from January 2004 to June 2012 and followed up with endoscopic examination periodically for at least 1 year were enrolled. All multiple gastric lesions were subsequently treated with ESD and the medical records of the patients were retrospectively reviewed.
Results
In total, 643 patients were included. The mean duration of endoscopic follow-up was 45.27±27.59 (range, 12–148) months. Overall, 144 patients (22.4%) showed multiple gastric tumors during the follow-up period (44 synchronous [6.8%] and 100 metachronous [15.5%]). The cumulative incidence rate steadily increased during the follow-up period. More than 50% of the tumors that developed at the same longitudinal location of the stomach were of the same macroscopic and histological type as the primary lesions.
Conclusions
Because synchronous and/or metachronous gastric tumors are common, considerable attention should be paid to detect multiple gastric lesions after ESD of early gastric neoplasm.
