Esophageal dysfunction in scleroderma: relationship with disease subsets.

OBJECTIVE: To investigate the relationship between esophageal function and the extent of disease in a nonselected group of scleroderma patients, and to study gastric and small bowel motility in a group of scleroderma patients with more severe clinical manifestations. METHODS: Esophageal function in 125 scleroderma patients was investigated by radiologic, endoscopic, manometric, and pH-metric techniques. Ten patients also underwent gastrointestinal (GI) manometric recording, both during fasting and after a standard meal. RESULTS: Radiologic abnormalities of the esophagus were found in 55 of 81 patients (68%) and esophagitis in 45 of 125 (36%). No significant relationship was disclosed between GI symptoms, radiologic abnormalities, esophagitis grade, and the various disease subsets. However, the overall incidence of endoscopic esophagitis (irrespective of the degree) was significantly (P < 0.05) correlated with the patient subgroups, with 100% incidence of esophagitis in those having the more severe cutaneous involvement (type III). Manometric abnormalities were documented in 80% of patients, and pathologic reflux in 78%. The severity of esophageal abnormalities on manometry significantly correlated with the severity of the disease, whereas no correlations were found with pH-metric data. Ninety percent of the 10 female patients undergoing antroduodenal manometry displayed abnormal findings; of these, 60% showed neuropathic, and 30% myopathic, patterns. The latter were recorded in patients with a more severe stage of the disease (type III). CONCLUSION: A direct relationship was observed between scleroderma subsets and the severity of esophageal (and, probably, more distal gut) motor involvement. Since no correlation was found between esophageal symptoms and the severity of manometric abnormalities, manometry should be considered the single most important GI test to document the severity of the "esophageal" disease. Gastric and small bowel manometry may also offer evidence of widespread gut involvement, and provide a rationale for a more targeted therapeutic approach.

[Gallbladder carcinoma. Our experience].

The authors report their experience of 18 patients with primary cancer of the gallbladder. On 10 patients at stage IV, 9 had a preoperative diagnosis, while at stage 0-1 and 2 the diagnosis was intraoperative or histologic. Every patient had a cholelithiasis at the same time. The authors discuss prophylactic cholecystectomy, even without specific symptoms, and emphasize the need for a better morphological and radiomorphological classification. In the light of the new microinvasive surgical techniques, they briefly discuss laparoscopic cholecystectomy and histologic diagnosis of carcinoma of the gallbladder.

Surgery of the incidentally discovered mass of the adrenal gland (incidentaloma).

The authors present their experience about surgery in adrenal gland incidentaloma, during a period of 12 years (1982-1993), at the VI Division of General Surgery, University of Turin. In 17 patients, of 70 who underwent adrenalectomy, the adrenal neoplasm was located thanks to a diagnostic investigation (ECI or CT) executed for other reasons. In ten cases was diagnosed adenoma, in five cases carcinoma, in two cases cysts. In the diagnostic approach to adrenal incidentaloma we did not search for possible hormonal activity, since the patients had been previously selected from specialized endocrinological centres. At present, biological markers not being certain or absolute radiological significance so as to detect benignant from malignant forms. In accordance with international Literature the size of the neoplasm is the discriminant element for adrenalectomy. We have removed the incidentaloma in all cases, be it clinically or subclinically functional and the silent forms > 4 cm as we have observed a statistically significant difference (p < 0.0002) between the benign and malignant lesions, particularly those measuring more than 4 cm in diameter. We suggest a screening with CT scan every three months in lesions < 4 cm, silent and those > 4 cm in patients over sixty years with a morphological aspect of the bening form.

Primary hyperaldosteronism. Analysis of risk factors associated with persistent postoperative hypertension.

Between 1983 and 1992, 24 patients with primary hyperaldosteronism were operated at our division. Among these, 21 had adrenal adenoma and constituted the subjects of our study. The aim of this retrospective study was to determine risk factors that could potentially lead to persistent arterial hypertension (5 cases or 23.9%). The variables of the univariate and the multivariate analyses were: sex, age, diameter of the neoplasm, preoperative duration of the hypertension, and familial hypertension. The analysis demonstrated no statistically significant difference between the resolution of hypertension and the variables. Though not statistically significant, the only variable that approached statistical significance (p < 0.11) was familial hypertension.
