METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, 3apan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis. RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3 out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm. CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel.展开更多

The Patency capsule is a new non-endoscopic dissolvable capsule which has as an objective of checking the patency of digestive tract, in a non-invasive manner. The available clinical trials have demonstrated that the Patency capsule is a good tool for assessment of the functional patency of the small bowel, and it allows identification of those patients who can safely undergo a capsule endoscopy, despite clinical and radiographic evidence of small-bowel obstruction. Some cases of intestinal occlusion have been reported with the Patency capsule, four of them needed surgery. So, a new capsule with two timer plugs (Agile capsule) has been recently developed in order to minimize the risk of occlusion. This new device stars its dissolution process earlier (30 h after ingestion) and its two timer plugs have been designed to begin the disintegration even when the device is blocked in a tight stricture.展开更多

The “ patency capsule" is a self- dissolving capsule that is the same size as the video capsule. It contains a radiofrequency identification (RFID) tag that allows it to be detected by a scanning device placed on the abdominal wall. When its passage is blocked by a stenosis, the patency capsule dissolves in 40- 80 hours after ingestion. The aim of this study was to evaluate the usefulness of this system in patients with suspected intestinal stenosis but also requiring VCE. Patients and methods: 22 patients (16 men; 46 ± 18 years; 15 with diagnosed or suspected Crohn’ s disease, two with suspected intestinal tumor, and two on nonsteroidal anti- inflammatory drugs) were first investigated with an abdominal CT plus enteroclysis (entero- CT, n = 15) or a small- bowel follow- through (SBFT, n = 7). The patency capsule was then administered at around 09.00 to fasting patients. The presence of the patency capsule in the digestive tract was assessed 30 hours later using the hand- held scanner. When the patency capsule was detected, a plain abdominal film was obtained, and this was repeated every 24 hours until capsule expulsion. Results: At 30 hours after ingestion, the patency capsule was detected in 17 patients (72.3% ): in the area of the small intestine (n = 6) and in the colon (n = 11). In all the patients in whom the capsule was blocked in the small intestine, the stenosis had been suspected on CT or SBFT. In three patients, the delay in progression of the patency capsule led to cancellation of the VCE procedure. In three patients, the patency capsule induced a symptomatic intestinal occlusion, which resolved spontaneously in one and required emergency surgery in two. Although these two patients would have been obliged to undergo operation for their primary disease in any case, the procedure had to be brought forward. In one patient, the capsule passed through the sten展开更多

Intraluminal strictures are an uncommon cause of SBO. This report describes our findings in a unique case of sequential, stenotic intraluminal strictures of the small intestine, discusses the differential diagnosis of intraluminal intestinal strictures, and reviews the literature regarding intraluminal pathology.展开更多

In addition, we evaluated the software of automatic detection of red zones (SBI, Given Imaging). Patients and methods -From June 2002 to June 2003, thirty-five patients with OGIB underwent capsule endoscopy after negative upper and lower digestive endoscopy. Capsule endoscopy was performed following a 12-hour fasting period and some received 2 L of PEG the night before for bowel preparation. Results -CE was performed for occult (N = 18) or overt (N = 17) OGIB. Potentially bleeding lesions were found in 16/35 patients (45.7%). Lesions were angiodysplasias (N = 8), ulcerations (N = 4), tumors (N = 2) and active bleeding without visible lesion (N = 2). Lesions were located in gastric antrum (N = 1), duodenum (N = 2) and jejuno-ileum (N = 13). Endoscopic (N = 10), surgical (N = 2) or medical (N = 1) treatments were performed in 13/35 (37%). SBI was retrospectively evaluated in 24 patients with sensitivity, specificity, positive and negative predictive value of respectively 45%, 73%, 50%and 69%. CE retention during 10 days occurred in a patient with a small bowel NSAID-inducea stricture. Conclusion -CE is a safe and effective procedure in the management of OGIB and had a therapeutic impact in more than one third of patients.展开更多
