[Correlation between hyperplastic and adenomatous polyps of the colon].

Problem: Although hyperplastic polyps are considered to be non-neoplastic, they nevertheless have a number of characteristics in common with adenomatous polyps.

Study Design: Since hyperplastic polyps and adenomas frequently occur together, the question arises as to whether hyperplastic polyps, found for example during sigmoidoscopy, might not be an indicator of possibly neoplastic polyps in the more proximal part of the bowel. In a retrospective analysis of first-time total colonoscopies in 685 patients, we investigated the relationship between hyperplastic and adenomatous polyps.

[Gallbladder motility in diabetic patients with and without cardiovascular neuropathy].

In 50 diabetic patients without gallstones, including 26 patients with cardiovascular autonomic dysfunction, and 60 normal volunteers the fasting volume and volume reduction of the gallbladder after a liquid fatty meal were determined ultrasonically in intervals of ten minutes up to one hour. Simultaneously the gastric emptying of the liquid meal was followed by ultrasound imaging. Despite an association of other complications of diabetic disease (peripheral neuropathy, retinopathy) with autonomic cardiovascular dysfunction, an altered gallbladder resting volume or impaired fat-induced volume reduction was not evident in this group of patients when compared the diabetics without cardiovascular dysfunction or controls.

[Splenic rupture following colonoscopy: an unusual complication].

A case of splenic rupture after an uneventful diagnostic colonoscopy in a 68-year old man is reported. Conservative management of this complication was successful. Splenic rupture is a unique and severe complication of colonoscopy, which can rarely be managed conservatively.

[Fasting volume and contractility of the gallbladder after total and subtotal gastrectomy with Y-Roux anastomosis. A prospective study].

Gallbladder volume and contraction after a fatty meal was determined in 14 patients with gastric cancer before and 3-4 months after gastrectomy (7 total and 7 subtotal gastrectomies) with Roux-en-Y anastomosis. All patients had an increased gallbladder resting volume (p less than 0.001) and 10 of 14 patients (6 after total gastrectomy and 4 after subtotal gastrectomy) had an increased minimal residual volume after fatty meal stimulation (p less than 0.

[Diagnostic value of ultrasonographic testing of the gallbladder function in cholelithiasis].

Decrease in gall-bladder volume after intake of a test meal was assessed by ultrasound in 30 patients (24 females, 6 males; mean age 55 [22-82] years) with indications for elective or early elective cholecystectomy for cholelithiasis. Patients were assigned to three groups, based on intraoperative and histological gall-bladder changes: group 1 (n = 17), without changes or with mild chronic cholecystitis; group 2 (n = 4), with severe chronic inflammatory changes; group 3 (n = 9), with acute cholecystitis or cystic duct occlusion. A volume decrease of at least 30% after the test meal excluded only acute wall inflammation (negative predictive value 95.
