Nearly one in ten individuals with asymptomatic gallbladder stones in the general population may be expected to develop symptoms or complications that require treatment within 5 years. Age may be inversely related to the incidence of complications.

Laparoscopic appendicectomy is as safe as open appendicectomy and has the advantage of allowing a quicker recovery.

A prospective study was performed to determine the frequency and type of bile duct abnormalities, and to determine whether routine use of intraoperative cholangiography during laparoscopic cholecystectomy might aid in the prevention of bile duct injuries. Overall, anatomical aberrations of the bile ducts were found in 98 (19 per cent) of 513 cholangiograms. The most common anomalies were at the hepatic confluence and constituted different types of right hepatic subsegmental ducts draining separately into the biliary tree (n = 43, 8.4 per cent), either close to the cystic duct or directly into the cystic duct. Three bile duct injuries (0.5 per cent) occurred during the study period. These results show that routine intraoperative cholangiography is feasible and provides valuable information about the anatomy of the biliary tract, thereby improving the safety of laparoscopic cholecystectomy. If an injury to the biliary tract occurs early during operation, the cholangiogram allows the surgeon to detect the injury, to make a prompt repair and thereby reduce the morbidity associated with a delayed diagnosis. Routine use of intraoperative cholangiography is strongly recommended.

The patterns of tumour histology, location and stage of gastric carcinoma have changed in the authors' region. These changes were paralleled by a significant improvement in survival and postoperative mortality rates.
