[Free bowel perforation as the onset and as a complication in the evolution of crohn's disease].
Free bowel perforation is a relatively infrequent complication of Crohn's disease. It may present during the evolution of the disease or, occasionally, in the onset of the same and may involve the small intestine or colon. We herein present 4 cases, three of ileal localization and one of colonic localization. In one of the 3 former cases and the latter case perforation took place prior to diagnosis of the disease. Review of the literature was performed with respect to the frequency, pathogenesis and characteristics of this complication and the importance of determined diagnostic techniques such as echography and CAT in addition to the most adequate treatment are commented upon.

[Significance of the determination of antineutrophil cytoplasmic antibodies (ANCA) in ulcerative colitis and Crohn's disease].
We have studied prospectively 126 consecutive patients recruited with a known diagnosis of ulcerative colitis (UC; n = 78) and Crohn's disease (CD; n = 48) for anti-neutrophil cytoplasmatic antibodies (ANCA) by indirect immunofluorescence (IFI). Forty-six percent of UC and 18% of CD patients were found positive. The sensitivity and specificity for UC diagnosis were 0.46 and 0.81, respectively. We evaluated the pattern of IFI exhibited (perinuclear: pANCA and cytoplasmatic: cANCA). cANCA was found in 77% of CD and in only 30% of UC patients (p = 0.01). Sera from all CD patients were positive at a 1:20 dilution (and not at higher dilution) and it occurred in only in 14 UC patients (30%). Positive sera were also tested to characterize the antigen specificity by enzyme-linked immunosorbent assay (ELISA) but the antigenic nature of ANCA could not be identified in most cases. No differences were found between ANCA positive and ANCA negative patients regarding colonic extension (UC) or colonic involvement (CD), activity and colectomy. We conclude that ANCA may be a helpful diagnostic test in UC patients but it not seems to be important as a marker of activity. ANCA positivity can reflect disease heterogeneity in UC patients, perhaps discriminating those with immunologic disturbances.

[Study of gastric emptying by dual isotopes. Corrections due to contamination].
The evaluation of gastric emptying by the double isotope technique involves some methodologic conditioning. Among them contamination correction or interference in the energy windows of the activity of the two isotopes used in the marking of the solids and fluids of the test food are important. The results of an experiment in which a phantom was used to evaluate the contamination between indio 111 (DTPA-Ca111In) and technecium 99m (colloid99mTc). Three test studies were posteriorly performed in healthy volunteers and 27 studies in a control group (13 males, mean age of 33 years, mean body mass index 39.02 kg/m). In these studies the contamination was corrected with the acquisition, following an initial swallow of juice marked with 111In, of activity in the windows of both isotopes. The contamination of 111In (isotope of greatest radiation energy) in the window of 99mTc was 24% in the phantom and 20%, 23% and 26% in the three initial study tests. The mean contamination in the control group was of 22% with limits of 19% to 29% and a standard deviation of 3%. Despite the comparable results, the usefulness of the individualized contamination calculation in the studies of gastric emptying with dual isotope to minimize the methodologic errors of this technique is discussed.

Relationship between smoking and colonic involvement in inflammatory bowel disease.
UNLABELLED: The effects of smoking on the onset and clinical course of inflammatory bowel disease (IBD) have been widely debated. Although smoking appears to have a clearly unfavorable effect on the course in Crohn's Disease (CD), the relationship between smoking and localization of the disease is less clear. AIM: To evaluate, in our group of patients, the relationship between smoking and the development of ulcerative colitis (UC) or CD, and between smoking and the localization of CD in the large bowel or in other sites. PATIENTS AND METHODS: The smoking habits of 171 patients at the time of diagnosis were assessed with a questionnaire. Subjects were classified into three subgroups as smokers, nonsmokers and ex-smokers. Current smokers were grouped according to their level of consumption as those who smoked fewer than or more than 10 cigarettes per day. A total of 161 patients were studied (UC n = 69, CD n = 92). Patients with CD were divided into those with colonic disease and those with no colonic involvement. We evaluated the relationship between smoking and the form of IBD, localization (colonic or noncolonic) and the presence of perianal disease (PAD) in CD. The results were analyzed with the chi-squared test. RESULTS: Smoking was more frequent in patients with CD than in those with UC (72.8% vs 31.9%). Among patients with CD, more patients without colonic involvement were smokers (84.6% vs 64.2%). However, among patients with CD involving the colon, smoking was significantly more common (64.2%) than among patients who had UC (31.9%). CONCLUSIONS: Our findings confirm a relationship between smoking and CD. Smoking seems to be associated with some degree of protection of the colonic mucosa, especially in heavy smokers.

[Familial prevalence in chronic intestinal inflammatory disease. Differences among groups of patients with and without a familial history].
OBJECTIVE: To assess the prevalence of familial occurrence in patients with inflammatory bowel disease and to evaluate the differences among groups of patients with and without familial history. PATIENTS AND METHODS: Complete information about sex, age of onset of inflammatory bowel disease, initial location, extracolonic manifestations and perianal disease (in Crohn's disease) was obtained from 187 patients, 99 with Crohn's disease, and 88 with ulcerative colitis. RESULTS: In 9 patients (9%) with Crohn's disease and 11 (12.5%) with ulcerative colitis, at least one first-degree relative also had inflammatory bowel disease. Three relatives of patients with Crohn's disease had ulcerative colitis and no relative of patients with ulcerative colitis had Crohn's disease. As compared with the group of patients with ulcerative colitis and no familial history, patients with familial history had more frequently distal location and extra-colonic manifestations. No differences were observed among patients with Crohn's disease and familial or non familial history. CONCLUSIONS: Prevalence of inflammatory bowel disease in relatives of patients with Crohn's disease or ulcerative colitis is increased. In ulcerative colitis, it is possible to segregate two different groups according to familial history.

[Sigmoid stenosis as a complication of severe acute pancreatitis].
We report a case of severe acute pancreatitis, of biliary etiology, complicated with a pancreatic pseudocyst and colonic stenosis localized in the sigmoid, that we interpret as secondary to the lesion produced by pancreatic enzymes spread. The treatment was surgical. Possible colonic complications in the context of an acute pancreatitis and their possible etiopathogenic mechanisms are commented. The incidence of these complications is rare and much more so the stenosis localized in the sigmoid colon.

Endoscopic sclerotherapy versus oesophageal transection in the prevention of variceal rebleeding.
OBJECTIVE: To compare sclerotherapy with oesophageal transection in the prevention of rebleeding in patients with oesophageal varices. DESIGN: A prospective trial. PATIENTS: Forty-one patients with cirrhosis and variceal bleeding. METHODS: After recovering from an acute episode of oesophageal variceal bleeding patients were randomized into two groups. One patient was excluded. Twenty-two patients were treated with sclerotherapy (group 1) and 18 underwent an oesophageal transection (group 2), with a shorter elapsed time from randomization to treatment in group 1. Both groups were similar with regard to clinical and biochemical features and variceal size. Failure, defined in group 1 as rebleeding or incomplete eradication after four sclerotherapy sessions, occurred in five (22.7%) patients; in group 2, rebleeding occurred in two (11.1%) patients (no statistically significant difference). CONCLUSION: Although the survival rate was similar in both groups, sclerotherapy is preferable to oesophageal transection because it requires a shorter duration of hospitalization and has fewer complications.

[Efficacy of 6-mercaptopurine in the treatment of inflammatory bowel disease].
OBJECTIVE: To assess the efficacy of 6-mercaptopurine in I.B.D. treatment. PATIENTS: 21 patients with chronic active disease (8 patients with ulcerative colitis and 13 with Crohn's disease) and mean follow-up 5 years for both diseases (range ulcerative colitis 1-11 and Crohn's disease 1-14 years, respectively). The indications of inmunosuppressor treatment were: corticosteroid dependence (3 ulcerative colitis; 6 Crohn's disease), refractory disease (5 ulcerative colitis; 4 Crohn's disease), fistulae (5 Crohn's disease) and perianal disease (4 Crohn's disease). All patients received a mean dose of 30 mg/day of prednisone. Complete, partial and clinical remission, of failure of treatment are defined. RESULTS: The mean dose of 6-mercaptopurine was 90 mg/day with a response mean time of 3.4 months and 12 months of duration (range 1-36). Complete or partial clinical remission was achieved in 77.7% of all the patients (steroid dependent 88.8%, refractory disease 77.7%, fistulae 40%, perianal disease 100% of all the patients (steroid dependent 88.8%, refractory disease 77.7%, fistulae 40%, perianal disease 100%), in 87% of ulcerative colitis patients (steroid dependent 100%, refractory 80%) and in 61.5% of Crohn's disease patients (steroid dependent 83.7%, refractory disease 75%). Secondary effects were observed in two patients. CONCLUSIONS: Our results suggest that 6-mercaptopurine is an effective and safe drug in the treatment of patients with ulcerative colitis and Crohn's disease in corticosteroid dependent, refractory and perianal disease, its efficacy being less in fistulae.

[Results of endoscopic dilatation treatment of benign esophageal stenosis].
The management of benign esophageal stenoses is based on endoscopic dilatation of the tight segment for the remission of dysphagia. Five hundred and twenty sessions of dilatation with Savary-Guilliard bougies have been performed in one hundred and twenty-nine patients with benign esophageal stenoses. Patients with peptic stenoses (n = 59) needed a lesser number of sessions (mean: 2.47) than patients with postsurgical (n = 44; mean: 4.86) or caustic (n = 18; mean: 7.77) stenoses. The treatment failed in 4 patients (3.2%) and severe complications were observed in 3 patients (2.4%). These results support the efficacy and safety of this technique.

[Endoscopic prosthesis insertion in the palliative treatment of malignant esophageal stenosis. (Endoscopic esophageal prosthesis)].
We report our experience with endoscopic esophageal prosthesis in the treatment of 82 patients with advanced malignant oesophageal stenosis. The cause of the stenosis was an esophageal or esophagogastric cancer in 75 cases and a bronchogenic cancer in 7 patients. In 18 cases a tracheobronchial fistula was also present. A silicone tube (Atkinson) was used in 58 patients, a polyvinyl tube (Wilson-Cook) in 22 cases and a self-expanding tube in the remaining 2 patients. There was no technical failure in the insertion of the prosthesis. A normal feeding was possible in 71 of the 82 patients (86%) within 48 after the intubation. Major complications occurred in 8 cases (9.7%), 4 patients with esophageal perforation and 4 cases with aspiration bronchopneumonia. Postoperative mortality rate was 7.3%, one patient with perforation, 3 cases with aspiration bronchopneumonia and 2 patients with sepsis. The prosthesis partially displaced in 9 cases, but could be endoscopically replaced in all of them. The displacement of the prosthesis was complete in 3 patients, one of which needed a surgical procedure to remove the tube. The prosthesis was bunged up by a solid meal bolus in 4 cases, but an endoscopic procedure was successful in removing the bolus. Therapy with laser was necessary in two cases with self-expanding prosthesis obstructed by tumoral growth. We conclude that, in malignant esophageal stenosis, the endoscopic implantation of esophageal endoprosthesis is an effective, cheap and relatively safe palliative therapeutic alternative with a low postoperative mortality rate.

[Esophageal pseudoachalasia related to a neoplasm].
Differential diagnosis between idiopathic achalasia and esophageal pseudoachalasia is difficult to perform. One hundred and forty-four consecutive patients with a clinical diagnosis of primary esophageal motor disorder have been evaluated for pneumatic dilatation of the cardias. Of them, 6 (4.1%) have been finally diagnosed of esophageal pseudoachalasia with carcinoma of the cardias, although in four cases more than one biopsy procedure was needed to establish the diagnosis. The clinical data--higher age, shorter clinical history and higher weight loss--, the higher pressure of the lower esophageal sphincter and the failure of the dilatation suggested the diagnosis, but were uncertain findings. Esophageal biopsy is the only objective method to obtain a definitive diagnosis and should be performed in every patient with an esophageal motor disorder evaluated for dilatation of the cardias and, if negative, it should be repeated when malignancy is suggested by available data.

[Isolated mesenteric tuberculosis as the first manifestation of AIDS].
We report a case of mesenteric tuberculosis. Two painful abdominal masses and fever were the first manifestation of disease. Diagnosis was obtained by aspirative punction of a mesenteric adenopathy guided by ultrasonography. AIDS risk factors were not recognized by anamnesis but serum HIV antibodies were detected. Thus, extrapulmonary tuberculosis and the finding of HIV-Ab confirmed the diagnosis of AIDS in our patient. It is necessary to assay for HIV-Ab in extrapulmonary tuberculosis, especially when mesenteric tuberculosis is present.

[Calcification of the portal vein associated with hepatocarcinoma].
We report a patient with alcoholic cirrhosis presenting with ascites, jaundice and malaise. Linear calcifications on the portal area were seen in the plain film of the abdomen. Computed tomography confirmed the presence of calcification of the portal vein wall and discovered lesions highly suggestive of diffuse multinodular hepatocarcinoma. We emphasize the rarity of portal vein calcification in patients with portal hypertension secondary to hepatic cirrhosis and hepatocarcinoma.

[Adult celiac disease and hepatopathy].
A retrospective study was performed in order to evaluate the prevalence of significant hepatic disease in patients with coeliac disease and its outcome after a gluten-free diet. Out of 46 patients with coeliac disease, 28 (60.87%) presented abnormal liver function test. These tests were normal after a gluten-free diet in 20 patients; one patient presented an acute B-virus hepatitis and in the remaining 7 patients a chronic liver disease was diagnosed (2 chronic persistent hepatitis, 1 chronic active hepatitis, 1 steatosis, 2 cirrhosis and 1 primary biliary cirrhosis). In conclusion, the high prevalence of significant hepatic disease in our patients with coeliac disease (15%) suggests an association between both disorders. Gluten-free diet does not modify the course of hepatic disease.

[Focal nodular hyperplasia of the liver: benign lesion with often surgical treatment. Magnetic resonance and laparoscopic findings].
The diagnosis of benign hepatic tumor lesions is every day more frequent. Three cases of focal nodular hyperplasia (FNH) accidently detected during the performance of echography and/or CAT for other reasons are presented. The difficulty or diagnostic doubts which the different imaging techniques may present before these findings, together with the relatively young age of these patients may lead to the adoption of a surgical attitude in lesions of a clearly benign character. The role of magnetic resonance (MR) as a non invasive diagnostic technique in this type of disease is of note.
