    Notes: Abstract We studied the motility of the sphincter of Oddi in 12 patients with suspected sphincter of Oddi dysfunction, in four patients with cystic dilatation of the bile ducts (two Caroli's cases and two fusiform choledochal cyst cases), and in 33 patients with retained common duct stones. In these last 33 patients, the motor activity of the sphincter of Oddi was similar to that recorded in nine control subjects without pancreatic or biliary diseases. In the suspected Oddi dysfunction cases, both the basal sphincteric pressure and the frequency of the phasic contractions were significantly elevated (P〈0.001). Patients with biliary cystic dilatation showed an increased basal pressure, but the frequency of the contractions was elevated in only those with choledochal cysts and the amplitude in only one of the two patients with Caroli's disease. Motor disorders of the sphincter of Oddi provide a basis for an alternative etiopathogenesis of cystic disease of the biliary system and a possible explanation for pain and dilatation of the bile duct in patients with suspected sphincter of Oddi dysfunction.

    Notes: Abstract In patients with achalasia, it has beensuggested that pneumatic dilatation could makecardiomyotomy more difficult to perform, diminishing itsefficacy and safety. Our aim was to evaluate theefficacy and safety of elective cardiomyotomy afterfailure of pneumatic dilatation in achalasia. During 14years, 32 of 276 consecutive patients with achalasiahave been operated on because of failure of dilatation therapy. Twenty patients have been followed-upfor at least one year after surgery. After failure ofdilatation, Heller's cardiomyotomy and 180 anteriorfundoplication were performed. Clinical status was evaluated before and after surgery. Loweresophageal sphincter pressure and esophageal body basalpressure were measured by manometry, esophageal diameterby barium meal, and gastroesophageal reflux by endoscopy and 24-hr esophageal pH monitoring.No technical difficulties were found during operation.Postoperative morbidity was infrequent and mortality wasabsent. Cardiomyotomy improved clinical status in 19 of 20 patients. The results of surgerywere considered excellent or good in 16 patients (80%;CI: 56-94%). The pressure of the lower esophagealsphincter was significantly reduced, falling in most patients to under 10 mm Hg. Gastroesophagealreflux appeared after surgery in eight patients, four ofthem with endoscopic esophagitis, but it was controlledin all patients with medical therapy. In conclusion, cardiomyotomy is a safe and effective therapyin achalasia after failed pneumaticdilatation.

    Notes: Abstract In this study we investigated the effect of selective (M1) and non-selective (M1 and M2) pharmacologic blockade of muscarinic receptors on cholecystokinin-induced gallbladder emptying. After validating the method of study, the gallbladder function was evaluated in 15 normal volunteers by quantitative biliary scintigraphy, and the effect of intravenous atropine (0.15 mg/10 kg) and pirenzepine (10 mg) was analyzed in each subject. Atropine significantly reduced the ejection period and the ejection fraction of gallbladder evacuation. Pirenzepine reduced the ejection period, but the ejection fraction remained unchanged. We conclude that the effect of cholecystokinin on gallbladder motility is mediated through muscarinic receptors. Our results suggest that M2 receptors, but not M1 receptors, are involved in this response.

    Notes: Abstract During nine years, 157 consecutive patients with achalasia have been dilated in our unit. First, the long-term effect of dilation on clinical status was evaluated. The probability of being in clinical remission eight years after first dilation was 51%. The pressure of the LES measured after dilation was highly predictive of the long-term clinical evolution. Second, a predictive model of the individual response to pneumatic dilation was developed and simplified. Therapy was effective in 80% of the patients, after one to four dilations. Younger age was the only factor significantly associated with ineffective therapy. Depending on the prognosis of the outcome calculated with the predictive model, patients were classified in groups of risk that showed a different rate of ineffective therapy. In the simplified model, age ≤20 years, male gender, esophageal body diameter ≤3 cm, esophageal body basal pressure 〉15 mm Hg, and pressure of the lower esophageal sphincter 〉30 mm Hg were predictors of a poor response to dilation. We conclude that pneumatic dilation is an effective therapy for achalasia. A predictive model was useful to classify the patients in groups with a different risk for ineffective dilation. A simplification of this model could be used to predict the response to dilation.

    Notes: Background.  Distinct human leukocyte antigen (HLA)-DQ genes have been associated with an increased or reduced risk for gastric cancer, but its association with Helicobacter pylori status is controversial. In the present study we evaluated the influence of host HLA DQA1 and DQB1 loci, H. pylori genotype, and socio-economic factors on predicting H. pylori-associated distal gastric cancer in a southern European population.Material and methods.  In a prospective case–control (1 : 2) study, 42 patients with H. pylori-associated distal gastric cancer were matched by age (±5 years) and gender to 84 patients with H. pylori-associated benign gastroduodenal disease (controls). The level of education received, smoking status, alcohol consumption, origin and familial history of gastric cancer were registered at inclusion. HLA DQA1 and DQB1 typing and H. pylori genotyping were determined from endoscopic gastric mucosal biopsies.Results.  Compared with control patients, a positive association with cagA+ strains (p 〈 .002) and a negative association with vacA-s2 strains (p 〈 .02) was found in patients with distal gastric cancer. At the DQB1 locus, the *0602 allele was more frequent in distal gastric cancer than in controls (26.2% vs. 4.8%; p 〈 .005). After correction for multiple comparisons (exact multiple regression analysis) the cagA+ status and the DQB1*0602 allele were associated with an increased distal gastric cancer risk (OR 3.7; 95% CI = 1.33–12.26 and OR 4.82; 95% CI = 1.24–19.83, respectively) whereas the vacA-s2 status was associated with a decreased risk (OR 0.33; 95% CI = 0.10–0.94).Conclusion.  Our findings suggest that in the H. pylori-infected southern European population, the cagA genotype and the HLA-DQB1*0602 gene confer an increased risk for distal gastric cancer.
