Factors predicting postoperative morbidity in biliary calculi.

Statistical analysis of a group of 1,114 patients operated for biliary lithiasis shows that the gravity of the disease, the nature of the complications that accompany it, the need to approach the common bile ducts (CBD) and age, stand at the origin of postoperative complications. To reduce postoperative morbidity elective surgery should be performed in cases of biliary lithiasis with paucity of symptoms during periods free of an attack and before the patient ages.
