[Duodenal diverticula].

Duodenal diverticula occur in 0.016 to 5.19% of patients undergoing roentgenographic investigation of the upper gastrointestinal tract. They are classified into extraluminal and intraluminal types and are usually found near the papilla of Vater. The majority of these cases are asymptomatic. These diverticula occasionally result in the obstruction of the biliary and/or pancreatic ducts, haemorrhage or perforation. Symptomatic cases may require endoscopic or surgical intervention. The management should be individualized to the kind of complication, type, and location of the diverticulum. Surgical procedures in this area may be technically difficult and associated with high mortality and morbidity. Elective treatment of uncomplicated duodenal diverticula is usually not justified. The difficulties in identifying these lesions as the source of symptoms are emphasized.

[Disease classification--how are bladder tumors registered? A questionnaire].

Sixty-one surgical departments in Denmark were asked how they used the three possible diagnoses: carcinoma in situ vesicae urinariae (D09.0), neoplasma benignum vesicae urinariae (D30.3) and neoplasma malignum vesicae urinariae (C67.9) for bladder tumours with specific reference to different stages and grades of the tumour. The answers from 59 departments demonstrated great variation in the classification of the same bladder tumour. This variation results in a registration of data which is not valid for a statistical outcome of the real incidence of benign and malignant bladder tumours in Denmark. A consensus from the Danish Bladder Cancer Committee, which will be published in 1996, concerning the criteria for the use of the different diagnoses for bladder tumours, should however in the future make it possible for all departments to make a uniform classification.

[Extracorporeal shockwave lithotripsy in the treatment of common bile duct calculi].

Fifteen patients with stones in the common bile duct, in whom treatment with endoscopic papillotomy and stone-extraction had been unsuccessful were treated with extracorporeal shockwave lithotripsy. Nine patients were stone-free after one or two sessions, and two patients after further endoscopic treatment. One patient achieved partial clearance and palliation. One patient had a choledochoduodenostomy performed due to ineffectiveness of the shockwave lithotripsy. Two patients, who were thought to have a stone, turned out to have neoplasma in the common bile duct. Complications were frequent but temporary and needed no treatment. We conclude that extracorporeal shockwave lithotripsy is a valuable and safe alternative in those cases where conventional endoscopic treatment has failed, and should be considered before operation, especially to old for high-risk patients.
