Post-operative lesions of the common bile-duct. A cholangiographic investigation.
Cholangiograms were reviewed of 190 patients with gall-bladder disease, who were consecutively operated upon with common bile-duct exploration during a 2.5-year period. Nine patients were excluded for various reasons. In 86 patients endoscopy of the duodenum was also performed after surgery. In 181 patients post-operative cholangiography revealed the following lesions, not found at the pre-explorative examinations: Fistula to the duodenum in 27, ulcers or sinus tracts in 11, ectasia and/or irregularities in another 11. In 17 patients retained calculi were found. The clinical significance of the iatrogenic lesions is probably low, but they must be recognized as such in order not to be radiologically misinterpreted.

Wheat fibre before radiography of the large bowel.
Constipation is today treated by adding non-absorbable fibres to a normal diet. The aim of this investigation was to study the influence of fibres on colon cleansing results in patients referred for double contrast examination of the colon. A series of 240 consecutive patients were separated into two groups, one treated with one day of starvation and the routine cleansing regimen, the other group with wheat fibres thrice daily for four days before the day of the regular cleansing program. No difference in cleanness between the two groups was seen.

Digitized intra-operative video-fluoroscopy cholangiography. An analysis of 100 cases.
Experience is reported of intra-operative fluoroscopy in 100 cholecystectomized patients using bilateral video- and tele-communicating systems between the surgeon and the conducting radiologist. The radiologist's guidance and the surgeon's realtime observation of the intra-operative study together with reduction in the mean operation time constitute the main advantages of this technique.

Radiographic findings in overlooked colon carcinomas. A retrospective analysis.
Double contrast barium enemas in 21 patients with primarily overlooked colon carcinomas were reviewed. The carcinomas were flat and measured less than 30 mm in 18 cases. These tumours constitute almost 1.4 per cent of the carcinomas diagnosed during a 12-year period. The retrospective analysis revealed the following signs of carcinoma: missing haustral folds, disharmony of interhaustral fold patterns; radiolucent filling defects; local contractions; residue-like masses and decrease of volume. In all cases, at least two secondary signs of carcinoma, range 1.7 to 3, were seen.

Bronchobiliary fistula in chronic pancreatitis. Case report.
Bronchobiliary fistulas are rare. One aetiological cause is biliary obstruction with secondary suppuration and subsequent hepatic and subphrenic abscesses. Only a few cases of bronchobiliary fistulas in patients with chronic pancreatitis have been reported and we record another case. A 47-year-old white male, with chronic alcohol-induced pancreatitis who had earlier undergone several laparotomies related to this disease, was admitted with a hepatic abscess. Drainage was not successful. The patient developed bilioptysis and a bronchobiliary fistula was diagnosed. The fistulous tract was demonstrated using PTC as well as bronchography. Laparotomy was performed and the fistulous tract was excised. The hepaticoduodenal ligament was completely obstructed by the inflamed pancreatic gland. An earlier but now obstructed cholecystojejunostomy was revised. This case was complicated by episodes of severe gastrointestinal bleeding probably caused by thrombosis of the portal vein and local varices around the gallbladder and common duct.
