Etiologic diagnosis of small bowel ulcer with double balloon enteroscopy / 中华全科医师杂志

Objective To assess the value of double balloon enteroscopy (DBE) in etiological diagnosis of small bowel ulcer.Methods The clinical and endoscopic data of patients undergoing DBE at the Department of Gastroenterology, Renmin Hospital of Wuhan University from January 2010 to January 2016 were reviewed.For patients with small bowel ulcer revealed by DBE, the etiologic diagnosis was retrospectively analyzed.Results One hundred and three patients with small bowel ulcer were included in the analysis.The initial diagnosis based on morphology of ulcer was Crohn's disease (58.3%, 60/103), intestinal tuberculosis (18.4%,19/103), etiology unknown (24.3%, 25/103).The final diagnosis comprehensively based on pathology, clinical data and disease outcome was Crohn's disease (44.7%,46/103), intestinal tuberculosis (18.4%,19/103), lymphoma (3.8%,4/103), eosinophils enteritis (1.9%,2/103), non-steroidal anti-inflammatory drug enteritis (1.9%,2/103), adenocarcinoma (1.0%,1/103), stroma tumor (1.0%,1/103),ischemic enteritis (1.0%,1/103), vascular malformation (1.0%,1/103), Henoch-Schonlein purpura (1.0%,1/103), etiology unknown (24.3,25/103).The accurate diagnosis rate and misdiagnosis rate for Crohn's disease by DBE were 73.3%(44/60)and 10.0%(6/60).The accurate diagnosis rate and misdiagnosis rate for intestinal tuberculosis by DBE were 14/18 and 2/18.Conclusion There are diversity and complexity in etiologic diagnosis of small bowel ulcer.The diagnosis should be based on the comprehensive analysis of morphology of ulcer, endoscopic and surgical pathology and clinical data.Follow up of small bowel ulcer by DBE may provide important information for etiologic diagnosis.

The role of capsule endoscopy in etiological diagnosis and management of obscure gastrointestinal bleeding

BACKGROUND/AIMS: To investigate the various etiologies, yields, and effects of capsule endoscopy (CE) on management and complications, along with follow up of patients with obscure gastrointestinal (GI) bleeding. METHODS: The study group of patients included those having obscure, overt, or occult GI bleeding. The findings were categorized as (A) obvious/definitive, (B) equivocal, or (C) negative. Any significant alteration in patient management post CE in the form of drug or surgical intervention was noted. RESULTS: Total patients included in the study were 68 (48 males and 20 females). The ratio of male:female was 2.4:1. The age ranged between 16 years to 77 years. Mean age for males was 62+/-14 years, for females 58+/-16 years. The total yield of CE with definitive lesions was in 44/68 (65.0%) of patients. In descending order (A) angiodysplasia 16/68 (23.53%), (B) Crohn's disease 10/68 (14.70%), (C) non-steroidal anti-inflammatory drug enteropathy 8/68 (11.76%), (D) small bowel ulcers 4/68 (5.88%), (E) jejunal and ileal polyps 2/68 (2.94%), (F) intestinal lymphangiectasis 2/68 (2.94%), and (G) ileal hemangiomas 2/68 (2.94%) were followed. Equivocal findings 12/68 (17.65%) and negative study 12/68 (17.65%) was found. Complications in the form of capsule retention in the distal ileum were noted in 2/68 (2.94%) subjects. Statistically, there was a higher probability of finding the etiology if the CE was done during an episode of bleeding. CONCLUSIONS: CE plays an important role in diagnosing etiologies of obscure GI bleeding. Its role in influencing the management outcome is vital.

Small Bowel Obstruction and Capsule Retention by a Small Bowel Ulcer That Was Not Found on Capsule Endoscopy / 대한소화기내시경학회지

Capsule endoscopy (CE) is a valuable modality for directly examining the small bowel in a relatively noninvasive and safe manner. CE is being increasingly used for obscure gastrointestinal bleeding, Crohn's disease, drug induced ulcer and small bowel tumor. Although capsule retention is a relatively infrequent complication, small bowel obstruction and strictures have been considered contraindications to CE. But some authors have reported that capsule endoscopy can be safely used to help identify the etiology and site of small bowel obstruction, and the retention of the capsule indicates the presence of a lesion requiring surgery. We report here on a case of small bowel obstruction and capsule retention by a small bowel ulcer, and the small bowel ulcer was not found when performing capsule endoscopy.

Perforation of idiopathic small bowel ulceration after blunt abdominal trauma in a child: a Case Report

Idiopathic small bowel ulceration occurring beyond the duodenum is rare, and less than 5% of all the reported cases have occurred in children. In most of the cases, single ulcer of unknown cause is observed in jejunum or ileum. The diagnosis is difficult and usually made at the time of surgical exploration for the complications, such as perforation, hemorrhage or obstruction. We experienced a case of perforation of idiopathic ileal ulceration due to blunt abdominal trauma in a 11-year-old boy. The ileal segment including the lesion was resected and the pathologic findings were compatible with idiopathic small bowel ulceration. The clinical and pathological aspects are discussed, and the literatures were reviewed.
