[Invagination caused by angiolipoma of the small intestine--a rare cause of occult gastrointestinal hemorrhage].

We present the case of a 71-year-old woman who was hospitalized because of a severe hip contusion. She had no symptoms or clinical signs of abdominal disease. Routine blood testing showed anemia, presumably owing to occult bleeding. Ultrasonographic abdominal screening revealed ileo-ileal intussusception with a central hyperechoic tumor suggestive of a lipoma as lead point. This diagnosis was confirmed at surgery, where a small bowel resection was performed. Histologic examination disclosed a benign angiolipoma of the ileum with a superficial shallow ulceration which obviously was the source of the occult blood loss. Diagnostic and therapeutic procedures and a literature review are discussed.

[Diagnosis in suspected appendicitis. Can ultrasonography rule out acute appendicitis?].

INTRODUCTION: Acute appendicitis is often difficult to confirm and even harder to rule out by physical examination. In order to assess the diagnostic reliability of sonography we compared the results of physical (p) and sonographic (s) examination. METHOD: One hundred and fifty consecutive patients presenting with right lower quadrant abdominal pain were evaluated in a prospective study. Based on the respective findings patients were classified into three groups: I: appendicitis confirmed; II: appendicitis ruled out; III: equivocal findings. The results were compared with the discharge diagnoses established by histologic examination or clinical observation. RESULTS: Ultrasonography showed significantly higher sensitivity (group I s vs group I p: 95% vs 45%) and specificity (group I s vs group I p: 100% vs 75%) in confirming as well as in ruling out acute appendicitis (group II s vs group II p: sensitivity 73% vs 53%; specificity 100% vs 81%) than physical examination alone. Owing to additional sonographic findings the group with indeterminate abdominal pain was much smaller after ultrasound examination (group III s vs group III p: 35 vs 69 patients). CONCLUSIONS: After discussing the literature and sonomorphologic criteria that distinguish an inflamed from a normal appendix, we conclude that ultrasonography is a valuable tool in confirming as well as in ruling out acute appendicitis.

Cryophlebectomy, a more recent technique in varicose veins surgery, was evaluated in comparision with conventional techniques. Group IA: Microphlebectomy, invaginative stripping of the long saphenous vein, tourniquet, n = 90; group IB: only microphlebektomie and tourniquet, n = 72. Group IIA: Cryostripping of the long saphenous vein in combination with cryosurgical distal avulsion of varicosities and microphlebectomy, n = 112; gr. IIB: only cryosurgical distal avulsion of varicosities and microphlebectomy. Data were compared regarding duration of operation and hospitalisation and cosmetic outcome. Hospital stay (gr. IA: 9.1 +/- 5.1 d vs. gr. IIA: 6.1 +/- 2.1 d, gr. IB: 5.5 +/- 2.3 d vs. gr. IIB: 4.8 +/- 2.5 d) and duration of operation (gr. IA: 113.6 +/- 35 min vs. gr. IIA: 67 +/- 21.3 min, gr. IB: 74.4 +/- 35.3 min vs. gr. IIB: 53.3 +/- 15.5 min) were found to be significantly shorter and cosmetic result and postoperative discomforts improved in the cryophlebectomy-group. We conclude that the use of this combination of methods reduces invasivity, rises the patient's well-being and helps in cost-reduction.

[Ultrasound criteria of gallstone ileus].

During a 4-year period we treated four patients with gallstone ileus by enterotomy and extraction of the impacted concrement. Diagnosis was quickly established by abdominal ultrasound examination in all cases. Lacking visibility of the gallbladder in the clinical setting of ileus and subileus proved to be a sonographic clue of gallstone ileus and prompted a thorough search for the obturating gallstone which could definitely be demonstrated as an intraluminal semicircular reflex with strong echos and a sonic shadow in all patients. Thus, due to early diagnosis and timely surgical intervention, even in the absence of full-blown ileus, all of our elderly patients and those with a multitude of diseases still had a favorable outcome.
