Double-balloon enteroscopy: a descriptive study of 50 explorations.

AIM: To evaluate the utility of double-balloon enteroscopy for small-bowel disease. DESIGN: A prospective study of 50 consecutive enteroscopies performed from December 2004 to July 2005 to analyze diagnoses and treatments. PATIENTS: 44 patients (33 had undergone a previous capsule endoscopy) with indications for obscure digestive hemorrhage, angiodysplasia, Peutz-Jeghers syndrome, ulcer, suspected Crohn's disease, tumors, and refractory celiac disease. RESULTS: We carried out enteroscopy studies in 44 patients by the oral route and, in 6 additional patients, by both the oral and anal routes. We reached the ileon with the oral route in all cases but one (jejunal stenosis), and in 4 cases out of 7 with the anal route, with an average duration of 73 minutes. We found angiodysplasia in 19 cases, as well as NSAID-related enteropathy, Crohn's disease, diverticulosis, and Waldenström's disease. We performed biopsies in 31% of cases with diagnoses of adenocarcinoma, lymphangiectasia secondary to tumor in celiac disease, and Whipple's disease. We treated 19 patients with angiodysplasia (1 to 20 synchronous lesions) with argon, and 4 patients with polyps using polipectomy (sporadic polyps or Peutz-Jeghers syndrome). A retained capsule in one patient with stenosis was removed. CONCLUSIONS: Double-balloon enteroscopy is a useful and effective technique in the diagnosis and treatment of small intestine diseases, thus complementing capsule endoscopy. More studies are needed to analyze its impact on the management of this condition.

[Gastrointestinal alterations in a female patient with common variable immunodeficiency].

We present the case of a 33-year-old woman who complained of intermittent diarrhea over the previous 8 years and who was diagnosed with common variable immunodeficiency. The woman presented antral atrophic gastritis, partial atrophy of the duodenal villi, nodular lymphoid hyperplasia of the small intestine and lymphocytic colitis. We also review the literature.

[Brucella hepatic abscess. Report of a case and review of the literature].

Hepatic involvement in infections caused by Brucella organisms is common but the production of liver abscess is exceptional. Therefore, the most appropriate therapeutic approach is unclear. The use of antibiotics can be effective but in some cases abscess drainage is required. We report here a case of brucellar hepatic abscess and a review of fourteen cases reported in the literature. An emphasis is laid on the clinical, laboratory and radiological findings, treatment, and patient evolution. On the basis of the reported cases a therapeutic approach is proposed.

[McArdle disease: report of four brothers with myophosphorylase deficiency].

Myophosphorylase deficiency, or McArdle disease, is an uncommon entity. The gene for human myophosphorylase has been cloned and is located on chromosome 11, in keeping with the autosomal recessive nature of the disease and there is an excess of male patients. The diagnosis is established by documentation of elevated glycogen content and reduced phosphorylase activity in biopsied muscle tissue. We report four cases with McArdle disease which were 16, 15, 11 and 5 years old. They were brothers, and they came to the hospital because of pain, cramps and myoglobinuria after exercise or infection; in the first case, a male patient, myoglobinuria caused acute renal failure. Three of them showed reduced phosphorylase activity in biopsied muscle tissue. We discuss the different therapeutic possibilities.
