Balloon probe for the colonoscopic small intestinal enema (CE).

The colonoscopic small intestinal enema (CE) permits the radiological examination of a large portion of the distal small intestine during colonoscopy. The colon (endoscopically) and the small intestine (radiologically) can thus be examined in one session. With a new balloon probe that can be passed through the instrumentation channel of the endoscope, it is no longer necessary to prepare the colonoscope by fitting a circular balloon as previously described, before introducing it into the patient. With the balloon probe, CE can be carried out at any time if an unexpected finding such as inflammation of the ileo-cecal valve makes the examination of the ileum desirable.

Angiodysplasia in the colon and rectum. Endoscopic morphology, localisation and frequency.

In a prospective study, the occurrence of angiodysplasia was investigated by total colonoscopy in 1938 patients. Angiodysplasia was found in 59 patients, i.e. 3%. 12 out of 59 patients were admitted for acute or chronic peranal hemorrhage or anemia. 47 out of 59 patients were asymptomatic. The site of the lesions was as follows: cecum 37%, ascending colon 17%, transverse colon 7%, descending colon 7%, sigmoid colon 18% and rectum 14%. Histological confirmation was obtained in 15 out of 37 biopsies. The endoscopic appearance was variable, most of the vascular dilatations being smaller than 5 mm (n = 47), with a homogeneous (n = 35) or inhomogeneous (n = 24) structure and a regular (n = 34) or irregular (n = 25) border. The lesions were single (n = 34) as well as multiple (n = 25), they were usually flat (n = 54), seldom slightly prominent (n = 5). Concomitant pathological findings in the bowel were diagnosed in 33 out of 59 patients: diverticula in 32%, adenomas in 24% and carcinomas in 8.5%. Right hemicolectomy for bleeding angiodysplasia is indicated only if endoscopic therapy has failed and other colorectal sources of bleeding, and especially angiodysplasia in the left colon and rectum have been excluded by endoscopy or angiography.

[Colorectal angiodysplasias (vascular ectasias). Endoscopic morphology, localization and incidence].

In a prospective study, angiodysplasias were looked for in 824 patients during total coloscopy. Such angiodysplasias were discovered in 30 patients (3.6%). The endoscopic morphology varied, most of the angiodysplasias being smaller than 5 mm (23 patients), with a homogeneous structure in 19, spider-like extensions in only 11 patients. In 13 patients there were multiple angiodysplasias. Two or more segments of the colon were affected in 7 patients. Site of lesions was as follows: in 19 patients in the caecum and/or ascending colon; descending colon, sigmoid and/or rectum in 16; transverse colon in 3 patients. Histological confirmation was obtained in 9 of 20 patients who had a biopsy. Right-sided colectomy for bleeding angiodysplasias (resulting in anaemia) is indicated only if endoscopic coagulation has failed and other colorectal sources of bleeding (neoplasm, diverticulum or polyp) and especially angiodysplasias in the left colon or rectum have been excluded by endoscopy or angiography.

[Endoscopic extraction of gallbladder calculi].

Endoscopic extraction of gallbladder stones were performed, as far as we know for the first time, in three patients with combined choledochocystolithiasis. Following endoscopic papillotomy (EPT) and subsequent mechanical lithotripsy of multiple choledochal concrements measuring up to 3 cm the gallbladder stones were successfully extracted with a Dormia basket through the cystic duct. The patients have remained free of complications after the endoscopic intervention.

[Coloscopic small intestinal enema].

Coloscopic small bowel enema, a new diagnostic method, permits small and large intestinal investigation in one session. A coloscope is required equipped with a circular mounted balloon at the distal end. The endoscope is placed into coecum using the conventional technique (coloscopy). After intubation of the ileocoecal valve the balloon is inflated in the terminal ileum. This prevents reflux of the contrast medium and methyl-cellulose solution which are instilled into the small bowel through the endoscope instrumentation bore. Double-contrast investigation of the small bowel is particularly suitable for diagnosis of inflammatory diseases (e.g. Crohn's disease), Meckel's diverticulum and polypoid lesions such as carcinoid tumours.

[Stenosis endoscope. A new instrument for the diagnosis and therapy of stenoses in the gastrointestinal tract].

A new type of endoscope combines the advantages of the narrow-calibre paediatric endoscopes and the stable-shaft regular endoscopes. This is achieved by reduction of the distal diameter from 13 mm to 9,5 mm with a conical transition between both parts. These characteristics make the instrument particularly suitable for the diagnosis of gastrointestinal stenoses (stenosis endoscope). At the same time the stenosis endoscope dilates as well as a metal olive or a rubber bougie. Thus dilatation of gastrointestinal stenoses is now possible beyond the reach of instruments used as bougie or for dilatation until now. The stenosis endoscope opens new possibilities of therapeutic endoscopy.

Short-channel duodenoscope: innovations in selective biliography.

The selective cannulation of the intrahepatic branches of the biliary system is made possible by the use of torsion-stabilized angiographic catheters passed via short-channel duodenoscopes. Other feasible applications are the endoscopic selective positioning of biliary endoprosthesis, and the cannulation of the gall bladder using a cysto-nasal catheter through which a litholytic fluid can be installed directly into the gall bladder.
