Therapeutic push enteroscopy (TPE) is useful when bleeding from small bowel lesions
occurs and endoscopic access is difficult. We have reported previously that push enteroscopy
is useful in diagnosis of Crohn9s disease (CD) without macroscopic lesions in the
colon and upper digestive tract, because macroscopic and microscopic findings [1]. Complications in the proximal small bowel are rare, but in some cases surgery in
duodenal and jejunal stenosis requires intestinal derivation and changes in their
medical approach. Endoscopic dilation of stenosis in CD is a good treatment in the
colon and upper digestive tract. We report an alternative technique by TPE in the
jejunum.
A 37-year-old man with CD suffered from vomiting and gastric pain without inflammatory
disease activity. The findings of upper endoscopy as far as the Treitz angle were
normal, but there was food retention. Enteroclysis revealed multiple stenoses in the
jejunum and upper digestive subobstruction. Colonoscopy with ileoscopy showed normal
findings. The patient underwent TPE (Fuji video enteroscope 200 WM) and multiple fibrous
stenoses in the proximal jejunum were confirmed 10 - 40 cm below the Treitz angle
(Figures [1], [2]). We then used a special long (3500 mm) balloon dilator (Olympus, Medical Europa,
Barcelona, Spain) with filled contrast over a 0.035-inch guide wire to make successive
dilations of all the strictures (Figure [3]). The balloon was inflated up to 2 cm over 2 minutes. Finally, the enteroscope was
passed through the distal jejunum. The jejunal biopsies taken after dilation revealed
CD without malignancy. After 3 weeks, we carried out another dilation, and 18 months
later, the patient was in an optimal state of health.
In the upper digestive tract repeated dilations are successful in CD in continuing
to prevent the need for surgery if the dilation reaches up to 2 cm in order to prevent
recurrence [2]. The use of combined radiology [3] is important for the evaluation of morphological aspects before and after dilation.
The edema or fibrous component of the stricture is the main factor to explain recurrences
and in some cases two or more sessions are needed. The dilation procedure with TPE
in small-bowel stenosis is quick, relatively simple, and within reach of most endoscopists;
moreover, its tolerance is acceptable. The possibility of associated malignancy is
also evaluated. To our knowledge, this is the first report which describes the usefulness
of TPE in the dilation of jejunal CD.
