    Notes: Abstract Background: Recent studies have documented the feasibility of ultrasonography (US) to diagnose acute colonic diverticulitis (ACD). This prospective observational trial determined the sonomorphology of ACD and evaluated the diagnostic accuracy of routine US performed on admission by surgeons in training. Methods: Fifty-seven consecutive patients with a confirmed episode of ACD were entered into this study, and the sonomorphology of the involved colon was assessed. US findings were compared to the results of the clinical evaluation and correlated to the clinicopathological outcome. Results: The sonomorphology of ACD was characterized by segmental inflammatory transformation of the colon averaging 9.9 ± 3.2 cm (range, 6–20) in length and visualized as target phenomena of a mean 3.5 ± 0.8 cm (range, 2.4–4.8) width. Targets were caused by hypoechogenic thickening of the colonic wall of an average 7.7 ± 2.6 mm (range, 4–18). In 40% of cases, a hyperechogenic halo representing peridiverticulitis (average width, 2.3 ± 0.6; range, 1.2–3 cm) was noted. Diverticula were seen in almost half of the cases. Of the 57 cases with confirmed ACD, the diagnosis was made by US in 48, for a global accuracy of 84.2%. US was false negative in nine patients, suggesting perforated appendicitis in five cases and acute appendicitis in one (the final diagnoses were perforated sigmoid diverticulitis in five cases and cecal diverticulitis in one case). In three patients, US was nondiagnostic. Conclusion: In the hands of sonographically trained surgeons, ultrasound is a useful modality to image acute colonic diverticulitis. US reveals diagnostic sonomorphology in most cases of ACD and therefore facilitates early confirmation of the diagnosis and assessment of severity.

    Description / Table of Contents: Zusammenfassung Die klinisch relevanten Daten von 126 Patienten, die sich zwischen dem 1.1.1987 und dem 31.12.1990 wegen eines Nebenschilddrüsenadenoms an der Klinik für Allgemeinchirurgie der Philipps-Universität Marburg einer Erstoperation unterzogen, wurden prospektiv dokumentiert. Bei 6 Patienten (4,8 %) wurden insgesamt 7 zystische Adenome gefunden. Bei gleicher Alters- and Geschlechtsverteilung wiesen Patienten mit zystischen Adenomen deutlich höhere Serumspiegel für Parathormon and alkalische Phosphatase auf als die mit soliden Adenomen. Der Serumkalziumspiegel in den beiden Gruppen war nicht unterschiedlich. Zystische Adenome waren deutlich schwerer als solide Adenome. Ein erheblicher Anteil der zystischen Adenome war in das hintere Mediastinum verlagert. Die Eigenschaft zystischer Nebenschilddrüsenadenome, häufig nicht an den normalen anatomischen Positionen zu liegen, kann bei ihrer intraoperativen Suche zu Schwierigkeiten führen.
    Notes: Summary Between 01. 01.1987 and 31.12.1990 a primary operation was performed on 126 patients in the Dept. of General Surgery, University of Marburg Hospital for primary hyperparathyroidism due to a parathyroid adenoma. Their clinically relevant data were prospectively documented. In 6 patients (4.8%) a total of 7 cystic parathyroid adenomas was found. While there was no difference in age- and sex-distribution, patients with cystic adenomas were found to have markedly higher serum parathormone and alkaline phosphatase levels than patients with solid adenomas. Calcium levels were similar in both groups. Cystic adenomas were much heavier than solid adenomas. A significant number of cystic adenomas was found to be displaced into the posterior mediastinum. The property of cystic parathyroid adenomas to be frequently located away from their usual anatomical position can make the intraoperative search for them difficult.
