[Value of sonography in diagnosis of uncertain lesions of the abdominal wall and inguinal region].

In a prospective trial we investigated the value of ultrasound in 134 patients with clinical doubtful findings of the abdominal wall and inguinal region. Ultrasound diagnosis was made by predefined criteria. In 105 patients a definite diagnosis was made by means of operative findings, CT, NMR, or puncture. In 40 patients a hernia was found. The sensitivity of ultrasound was 85%, the specifity 93.8%, the positive predictive value as 89.5% and the negative predictive value was 91%. Separating the findings to localisation of the hernia results in highest sensitivity for epigastric hernia (100%) and lowest for crural hernia (72.7%). The specifity for all hernias was more than 96%. Liquid tumors (hematom, serom, abscess) could be differentiated from solid tumors (lymphom, metastatic nodule, lipom). The most frequent course of wrong diagnosis was mixing the different liquid or solid tumors among themselves because of similar sonomorphologic properties. The sensitivity for hematom, serom, abscess, lymphom and metastatic nodule was 87.5%, 100%, 66.6%, 77% and 85.7% respectively. The corresponding specifity was 97.8%, 97.8%, 100%, 96.7% and 98%. Ultrasound was found to be of value for the diagnosis of clinical indeterminal findings of the abdominal wall and inguinal region.

[Results of treatment in esophageal cancer].

204 patients were treated for esophageal cancer from 1.1.1986 until 1.6.1992 (carcinoma of the hypopharynx: n = 12, adenocarcinoma of the endobrachyesophagus: n = 82, primary esophageal cancer: n = 110). Out of the primary esophageal cancers 84 tumors (76%) were resected and 24% had palliative endoscopic and/or irradiation therapy. The stage distribution of the resected patients was: stage I: 7.1%, stage IIa: 35.7%, stage IIb: 11.9%, stage III: 33.3%, stage IV: 11.9%. The total morbidity of the resected patients amounted to 32.1%, the 30 days mortality to 7.1%, and the in hospital mortality to 9%. These data show no significant difference to the results of palliative endoscopic procedures (morbidity: 42.3%, mortality: 7.7%). None of the conservatively treated patients survived longer than 12 months whereas resected individuals had a 5-year-survival rate of 20%. The most predictive factors for prognosis were: Depth of tumor invasion (p less than 0.01), R-classification (p less than 0.05), and the lymphonodular status (p less than 0.05). A perioperative irradiation was effective in T3- and T4-tumors.

[Jejunal diverticulosis--a rare cause of gastrointestinal hemorrhage].

We report a case of gastro-intestinal bleeding caused by jejunal diverticulosis, in which preoperative diagnosis could be achieved by selective angiography. Even though the small bowel is a rare localisation of bleeding (1% of all cases), this part of intestine should be included into diagnostic considerations. Jejunal diverticulosis only requires operative treatment after occurrence of complications, small bowel resection is regarded as treatment of choice in these cases.

[The value of sonography in the diagnosis of appendicitis. A prospective study of 100 patients].

Between October 1988 and July 1989 100 consecutive patients with suspected appendicitis were seen at the surgical clinic, University Hospital of Aachen. All patients underwent ultrasonographic examination corresponding to a prospective study protocol in order to determine the value of ultrasound for the diagnosis of acute appendicitis. The sonographic findings were correlated with the histologic diagnosis or the clinical course, respectively. We found a sensitivity of 100% for appendiceal mass, of 88% for phlegmonous appendicitis and of 25% for catarrhal appendicitis. The overall sensitivity was 49% and the overall specificity rate was 97%. The overall accuracy rate was 64%. The predictive value of a positive test was 97% and the predictive value of a negative finding was 46%. The morphologic changes during the progress of inflammation of the appendix and their sonographic visualisation were discussed. A differentiated concept was developed to integrate the sonographic findings in the therapeutic decision.
