Diaphragm disease after use of nonsteroidal anti-inflammatory agents: first report of diagnosis with capsule endoscopy

Diaphragm disease of the small intestine is part of the spectrum of diseases associated with injury to the gastrointestinal tract induced by nonsteroidal anti-inflammatory drugs. Standard endoscopy or contrast studies of the small intestine rarely identify these lesions. The diagnosis usually is established at the time of surgery. We report the case of a 72-year-old woman with obscure gastrointestinal bleeding and intermittent obstruction of the small intestine who had had multiple hospitalizations and extensive testing. The patient had been treated with nonsteroidal anti-inflammatory drugs for osteoarthritis. A radiograph of the small intestine with barium contrast revealed no abnormalities, so capsule endoscopy was performed. Capsule endoscopy showed multiple small intestinal strictures beyond which the capsule could not pass. After the patient experienced continued symptoms suggestive of intermittent partial obstruction of the small intestine, computed tomography showed the capsule within a dilated loop of intestine adjacent to a stricture. After 9 days of conservative medical therapy and worsening symptoms, the patient required an exploratory laparotomy. The capsule was located in a 12-cm segment of intestine with 4 diaphragm-like lesions. Pathologic study found submucosal lesions with features identical to those of neuromuscular and vascular hamartoma (eg, mature, reactive tissue elements of smooth muscle, dense fibrous tissue, and nerve tissue bundles with scattered ganglion cells and vessels). No manifestations of Crohn disease were evident. This case represents the first diagnosis with capsule endoscopy of diaphragm disease of the small intestine with pathologic features of neuromuscular and vascular hamartoma.     

胶囊内镜对小肠疾病的诊断价值分析

目的 了解胶囊内镜检查在国人运用的临床特性，评价胶囊内镜对国人小肠疾病的诊断价值。方法 分析55例次胶囊内镜检查的临床资料。结果 (1)53例受检者进行了55次胶囊内镜检查，成功54次，成功率为98．2％。53例受检者均耐受了检查，未出现并发症。(2)胶囊内镜在胃内滞留平均时间为44min(6—135min)，小肠内滞留平均时间为334min(90—433mim)。在检查记录有效期间，胶囊内镜顺利通过回盲瓣42例，未通过12例。52例胶囊在检查结束后顺利排出体外，排出平均时间为24h(5h 10min～72h)。(3)检出了小肠癌、淋巴瘤、息肉、平滑肌瘤、黄色瘤、克罗恩病、非特异性炎症、蛔虫症、鞭虫症、异物及血管畸形等。结论 胶囊内镜检查操作简单、安全、有效，检查成功率高，对小肠黏膜、血管及黏膜下等病变的检出能力较小肠钡剂灌肠、血管造影为高，具有较好的诊断价值。胶囊内镜的最大缺点是观察不能重复，不能获得组织学诊断和较为准确的定位诊断。     

Morphological comparison of small nerve fibres in gastric mucosa in non‐diabetic and Type 2 diabetic subjects

Aim To determine changes in small nerve fibres in gastric mucosa in patients with Type 2 diabetes by morphological observation. Methods In twenty‐five non‐diabetic and 21 Type 2 diabetic participants, gastric mucosal biopsy under endoscopy was performed. Innervation in gastric mucosa was detected using immunohistochemical staining. Anti‐protein gene product (PGP) 9.5 positive nerves underwent morphological observation and quantitative analysis. Results Small nerve fibres in gastric mucosa were shortened in the diabetic subjects. The ratio of gastric mucosal protrusions maintaining nerve fibres between gastric pits to total observed protrusions was lower in patients with Type 2 diabetes compared with the non‐diabetic subjects (ratio of innervated protrusion/total protrusion: 0.49 ± 0.12 vs. 0.89 ± 0.06, P < 0.05). Conclusions This study sets the scene for further research to investigate the relationship between gastric mucosal nerves and autonomic neuropathy or diabetic peripheral neuropathy.

Obscure gastrointestinal bleeding: a complication of radiation enteritis diagnosed by wireless capsule endoscopy.

Obscure gastrointestinal bleeding is a common disorder and may account for as many as 5% of all gastrointestinal hemorrhages. It is often caused by lesions in the small intestine, which were very complicated to examine prior to the advent of wireless capsule endoscopy. Here we present the case of a 31-year-old woman with obscure gastrointestinal bleeding as a complication of radiation enteritis, which was diagnosed only after she underwent an examination with wireless capsule endoscopy. This technique has proven to be far superior to other radiographic and endoscopic methods in diagnosing obscure gastrointestinal bleeding and pathologies of the small intestine in general.     

Strictures from Crohn's disease diagnosed by video capsule endoscopy

Video capsule endoscopy is a new diagnostic modality that allows imaging of the entire small intestine. We report on a patient with a presumed but undocumented case of Crohn's disease who was found to have 9 ileal strictures by video capsule endoscopy. These strictures were undetected by small intestinal contrast studies and required surgical intervention. This case report suggests that small bowel radiographic studies may not be as sensitive for the detection of clinically significant luminal lesions as once thought.     

Investigation of the small bowel in gastrointestinal bleeding--enteroscopy and capsule endoscopy

The last frontier in luminal endoscopy has been conquered. Bleeding lesions in the small intestine can present a frustrating clinical problem, but recent advances have made investigating the small bowel easier and less invasive. Capsule endoscopy and double balloon enteroscopy are two new technologies that promise to lower the barrier to evaluation of the entire small intestine. Recent studies show that capsule endoscopy improves outcomes in patients who have OGIB. Although outcome studies regarding double balloon enteroscopy have not been performed, the opportunity to treat lesions throughout the small bowel without resorting to surgery is a tremendous advance. These improvements suggest that the corner may have been turned in the diagnosis and management of small bowel bleeding. Perhaps to the next generation of gastroenterologists, small bowel bleeding will not be obscure.     

Non-small-bowel lesions detected by capsule endoscopy in patients with obscure GI bleeding

BACKGROUND: Approximately two thirds of patients undergoing capsule endoscopy for obscure GI bleeding will have an abnormality found in the small intestine. This report describes 9 patients (4 men, 5 women) of 140 with obscure bleeding in whom a source of their blood loss was found in the stomach or the colon at capsule endoscopy. METHODS: A review was made of a prospective database of 140 consecutive patients undergoing capsule endoscopy for obscure GI bleeding at a single center. Patients with a definite or likely cause of bleeding within reach of conventional upper or lower GI endoscopy were identified. RESULTS: Three patients had gastric antral vascular ectasia and another an inflamed pyloric canal polyp. Two patients had actively bleeding cecal carcinoma, missed at previous colonoscopies. Two others had bleeding cecal angiodysplasia. The final patient had severe nonspecific cecal inflammation. The identification of these lesions was aided by the suspected blood indicator. All patients underwent endoscopic therapy or surgery for their non-small-bowel lesions. CONCLUSIONS: Like push enteroscopy, capsule endoscopy also can identify lesions within reach of conventional endoscopy and colonoscopy. These subsequently can be treated successfully. The reasons why these lesions have been missed are unclear.     

不明原因腹痛患者胶囊内镜检查的应用分析

目的探讨胶囊内镜在诊断不明原因腹痛的临床价值及安全性。方法将本院73例不明原因腹痛患者进行胶囊内镜检查,对检查结果进行分析。结果 73例患者中50例被检出小肠病变,检出率为68.49%。其中小肠克罗恩病6例、回肠多发性溃疡2例、小肠多发性毛细血管扩张1例、小肠息肉4例、小肠肿瘤1例、小肠寄生虫2例、小肠黏膜糜烂22例。12例分别为慢性浅表性胃炎、结肠炎、十二指肠溃疡。23例检查无异常。结论胶囊内镜操作简单、安全性高,对不明原因腹痛有较高的诊断价值。     

Capsule endoscopic features of Crohn's disease

Background: Crohn's disease (CD) is becoming increasingly recognized in Indian patients. As this disease often affects the small bowel, capsule endoscopy can help diagnose this disease and add valuable information regarding the extent of the disease. Our aim is to report our experience with the wireless capsule endoscope in patients with either known or suspected CD. Methods: Patients referred for capsule endoscopy with known or suspected CD were studied. All patients underwent precapsule endoscopy colonoscopy and small bowel series examination. After an overnight fast and bowel preparation, the capsule was ingested and the data were recorded for 8 h on the external recording device. A gastroenterologist experienced in reading capsule endoscopy interpreted images. Results: Eleven patients (mean age 42 years [range 14–70], 7 males) underwent capsule examination. Seven patients had symptoms suggestive of CD with no precapsule evidence of the disease, one had suspected small bowel pseudo‐obstruction and three had known CD. All patients had lesions in the small intestine consistent with CD. Two patients had strictures that led to a retained capsule, despite precapsule small bowel series. Conclusions: Capsule endoscopy is emerging as a small bowel imaging modality that can greatly assist in making the diagnosis of CD. Small bowel radiology is unreliable in excluding strictures that may cause capsule retention.
