BACKGROUND Capsule endoscopy enables noninvasive diagnostic examination of the entire small intestine. However, sensitivity and specificity of capsule endoscopy have not been adequately defined. We, therefore, compared capsule endoscopy by using intraoperative enteroscopy as a criterion standard in patients with obscure GI bleeding. METHODS Forty-seven(More)
GOALS The aim of this study was to evaluate our results of laparoscopic treatment of perforated gastroduodenal ulcers during a 5-year period and to compare the outcome of open and laparoscopic surgery. BACKGROUND The value of laparoscopic treatment of gastroduodenal ulcers is still controversially debated because its superiority to conventional open(More)
In a 25-year-old woman who was operated for superficial spreading malignant melanoma two years ago a slowly growing tumor in the gallbladder was detected sonographically. Since further screening for metastatic disease was negative the gallbladder was removed laparoscopically. To our knowledge this is the first laparoscopic cholecystectomy for a metastasis(More)
The number of foreign bodies remaining in the patient after a surgical procedure is presumably higher than mentioned in the literature. According to US insurance statistics, the incidence amounts to 1 in 1,500 surgical procedures. As a basic principle--also from the legal aspect--it is necessary to determine whether a foreign body was left in situ(More)
In the Surgical Clinic of the University of Münster Billroth II resection with Roux-en-Y gastroenterostomy was introduced 1974--with a specific modification-- and has now been performed in every case where primary or additional resections of the stomach were indicated. The main advantage is seen in the tensionless gastroenteral anastomosis even in cases(More)
The impact of quantitative parameters on the differentiation of primary colorectal tumours from normal colon tissue was assessed. Dynamic PET data (DPET) were acquired, and compartment and non-compartment modelling applied. The discriminant power of single parameters and the combination of PET parameters was assessed. All lesions were confirmed by(More)
A traumatic diaphragmatic hernia is a well-known complication following blunt abdominal or penetrating thoracic trauma. Although the majority of cases are diagnosed immediately, some patients may present later with a diaphragmatic hernia. A tension fecopneumothorax, however, is a rarity. We report on a patient who, 2 years after being treated for a stab(More)
BACKGROUND At present, long-term results after conservative treatment of morbid obesity (body mass index > 40) are not satisfying, given a relapse rate > 95%. In comparison, surgical treatment is about 10 times more efficient and, thus, more cost-effective. SURGICAL TECHNIQUES Currently performed surgical interventions to induce weight loss are dominated(More)
PURPOSE To report a case of successful endovascular treatment of an infected abdominal aortic aneurysm (AAA) following Salmonella septicemia. CASE REPORT A 60-year-old man was admitted for rapid onset of urinary frequency, fever, and suprapubic pain extending to the flanks. Blood cultures were positive for Salmonella enteritidis, and appropriate(More)
The growing popularity of laparoscopic cholecystectomy (LC) has made extensive series comparing laparoscopic and conventional cholecystectomy in a prospective, randomized way nearly impossible. To evaluate LC we compared retrospectively 800 laparoscopic with 748 conventional cholecystectomies (CC). Of the 800 LC, 10 (1.2%) were converted to laparotomy. 6(More)
