Painful irritable bowel syndrome and sigmoid contractions.

Fifteen patients with abdominal pain compatible with the irritable bowel syndrome (IBS) were examined by barium enema and pressure recording. Strong circular contractions of the sigmoid colon and pressure recordings correlated with the characteristic pain in 13 of the 15 patients. In 15 control patients no pain occurred. It is concluded that pain and high pressure are caused by strong circular sigmoidal contractions. Such findings enable the radiologist to contribute to the diagnosis of IBS.

[Motility of the sigmoid in irritable bowel syndrome and colonic diverticulosis].

The results of pressure recording in patients with irritable bowel syndrome, diverticulosis and diverticulosis with pain were compared with the results in control subjects. The motility showed variable higher values in patients with irritable bowel syndrome. The motility was clearly higher in patients with diverticulosis and in patients with diverticulosis with pain. The patients with irritable bowel syndrome were younger than the patients in the two groups with diverticulosis. These findings are consistent with the hypothesis that the irritable bowel syndrome is an aetiologic factor in diverticulosis.

Total talar dislocation.

Five patients with the very rare injury of a total dislocation of the talus were retrospectively studied. Rapid open reduction had successfully been performed in all patients. The mean followup was 4.5 years. Two cases developed an avascular necrosis of the talus. No talectomy was performed. The clinical results were good in three and fair in two patients. It is concluded that the choice of treatment is a rapid open reduction. In case of an avascular necrosis of the talus, weight bearing must be postponed. A talectomy must be avoided.

Cholecystokinetic cholecystography.

A prospective clinical trial of 100 patients receiving either intramuscular ceruletide or a fatty meal to contract the gallbladder after oral cholecystography is described. The percentage reduction of the gallbladder area after 30 min of stimulation was not significantly greater with ceruletide (49%) than with a fatty meal (44%) (t-test: p greater than 0.3). Ceruletide caused significantly more adverse reactions than a fatty meal (Fisher test, p less than 0.01). The diagnostic value of routine cholecystokinetic stimulation is doubtful, since the diagnosis changed after the contraction in only 1 patient.
