Background and Aims . There is no consensus so far regarding the optimal endoscopic method for treatment of small rectal neuroendocrine tumor (NET). The aim this study was to compare efficacy, safety, procedure time between submucosal resection with band ligation (ESMR-L) dissection (ESD). Methods We conducted a prospective patients who visited Inha University Hospital NET (≦10 mm). Pathological complete rate, time, complications were evaluated. Results A total 77 treated by ESMR-L...
The gastroprotective effects of BST-104 (a water extract Lonicera japonica) and the mechanisms involved were investigated in murine models gastritis peptic ulcer. its active components evaluated rat HCl/ethanol-induced acetic acid-induced gastric After orally administering BST-104, chlorogenic acid, rebamipide (positive control), or vehicle to each animal model, lesion sizes, mucus statuses, proinflammatory cytokine levels, oxidative stress measured. Superoxide dismutase (SOD), catalase,...
Risk Factors for Long-term Outcomes after Initial Treatment in HepatolithiasisHepatobiliary complications, such as stone recurrence, recurrent cholangitis, liver abscess, secondary biliary cirrhosis, and cholangiocarcinoma may occur treatment hepatolithiasis.However, few previous studies have addressed the risk factors longterm outcomes initial treatment.Eighty-five patients with newly diagnosed hepatolithiasis, actively treated constituted cohort of this retrospective study.Patients were by...
Background and Aim Transpapillary stent insertion is the standard treatment for palliating malignant biliary obstruction. However, luminal occlusion often occurs due to sludge formation, tumor ingrowth, or overgrowth. Currently, influx of duodenal contents by duodenobiliary reflux considered a mechanism The aim present study was evaluate efficacy safety metal with an anti‐reflux valve in distal Methods Thirty‐two patients diagnosed unresectable obstruction were enrolled. This trial conducted...
Esophageal fibrovascular polyps are rare, benign, submucosal tumors of the upper digestive tract that usually have an indolent course until lesion attains a very large size. The most frequent complaints associated with these include dysphagia and foreign body sensation. However, long pedunculated polyp can regurgitate into pharynx or oral cavity cause asphyxia sudden death if larynx is occluded. We describe case 51-year-old man who experienced snoring occasional during sleep. Upper endoscopy...
Large-cell neuroendocrine carcinoma of the colon is a rare entity with prognosis that usually poor due to high likelihood early metastasis.A 61-year-old man had surgery for cancer transverse and cecum.Microscopic examination tumor showed location was proximal colon, small nests containing rosettes palisading patterns large cells faintly granular cytoplasm.The immunohistochemistry positive synaptophysin chromogranins.The tumors were diagnosed as large-cell colon.In addition, cecum microscopic...
Background/Aims Fecal microbiota transplantation (FMT) is a highly effective therapy for refractory and recurrent Clostridium difficile infection (CDI). Despite its excellent efficacy recent widespread use, FMT has not been widely used in South Korea thus far. We describe our experience with to treat refractory/recurrent CDI. Methods conducted chart review of patients who underwent CDI at Inha University Hospital, between March 2014 June 2016. The demographic information, treatment data,...
Increasing clarithromycin resistance has led to the need for an alternative first-line therapy eradication of Helicobacter pylori (H. pylori) in Korea, and bismuth containing quadruple (BQT) tailored (TT) have been proposed as regimens. The aim this study was compare rates BQT TT H. therapies.H. infection diagnosed using rapid urease test or dual-priming oligonucleotide-based multiplex polymerase chain reaction (DPO-PCR) during endoscopy. Patients positive were divided into two groups; those...
We prospectively evaluated the usefulness of MDCT using a curved planar reformation technique for noninvasive assessment causes biliary stent occlusion in patients with malignant obstruction.Between December 2004 and January 2009, 173 unresectable obstruction underwent insertion. Among them, 26 suspected 29 sessions ERCP within 2 weeks after was performed. Curved images were obtained along pathway stent. interpreted tissue growth or clogging by comparing attenuation values inside between...
Laparoscopic Heller myotomy with antireflux procedure is considered to be a standard treatment for achalasia. Recently, peroral endoscopic (POEM) was developed and performed on patients However, there no report POEM use in South Korea. The aim of this study evaluate the technical feasibility porcine model.POEM two mini pigs. We upper endoscopy under general anesthesia. A submucosal tunnel created circular muscle layer incised using several knives. mucosal entry closed resolution clips....
Pseudomembranous colitis (PMC) is a nosocomial and opportunistic infection caused by Clostridium difficile. PMC related to the use of antibiotics leading intestinal dysbiosis an overgrowth C. Metronidazole or vancomycin considered be standard therapy for management PMC. However, has 15%-30% recurrence rate can refractory treatments, resulting in morbidity mortality. Here we describe patient who experienced was treated with fecal microbiota transplantation. A 69-year-old woman admitted...
Background/Aims Endoscopic papillary balloon dilation (EPBD) is a safe and effective method for the treatment of choledocholithiasis, but previous studies have rarely reported appropriate ballooning time (BT). We prospectively evaluated safety efficacy EPBD according to BT in patients undergoing bile duct stone removal. Methods Seventy consecutive with stones were randomly assigned receive either conventional (n = 35, 60 seconds) or short 20 BT. Results alone achieved complete clearance 67...
Colonoscopic examination is a safe procedure, however, unexpected complications can sometimes occur. Bleeding and perforation of the colon have been reported as most common complications. Hemoperitoneum after colonoscopy an unusual complication, but it may be catastrophic. We report on 20-year-old man who experienced left low quadrant pain undergoing colonoscopy. was diagnosed using abdominal CT. A laparoscopic exploration urgently performed, revealing lacerated mesocolon descending colon....
Ileal Dieulafoy lesion is an unusual vascular abnormality that can cause gastrointestinal bleeding. It be associated with massive, life-threatening hemorrhage and requires urgent angiographic intervention or surgery. hard to recognize due inaccessibility normal-appearing mucosa. With advances in endoscopy, aggressive diagnostic therapeutic approaches including enteroscopy have recently been performed for small bowel We report two cases of massive ileal bleeding diagnosed treated successfully...
A 69-year-old man underwent upper endoscopy at our hospital to evaluate gastric discomfort. He had undergone a subtotal gastrectomy for advanced cancer 2 years earlier, but been lost follow-up. An endoscopic examination revealed numerous (> 100) sessile polypoid mucosal nodularities. Their mucosa characteristic verrucous appearance similar papillomatous skin warts extending from the piriform sinus esophago-gastric junction (Fig. 1). size ranged 1 10 mm. Histologically, biopsies taken...
Background/Aims In Korea, there are no available multicenter data concerning the prevalence of or diagnostic approaches for non-responsive gastroesophageal reflux disease (GERD) which does not respond to practical dose proton pump inhibitor (PPI) in Korea. The purpose this study is evaluate and symptom pattern GERD. Methods A total 12 hospitals who were members a Korean GERD research group joined study. We used composite score (CS) as scale standardized questionnaire based on frequency...
