Laparoscopic cholecystectomy.

Cholelithiasis is being recognized more frequently in the pediatric population. Although hemolytic diseases have an identifiable etiology, the origin of gallstones in approximately 80% of pediatric patients remains unknown. Infants with cholelithiasis can be managed expectantly unless symptoms develop because many of these stones will resolve spontaneously. The 2- to 12-year age group is more likely to present with chronic cholecystitis and will require cholecystectomy at some point, since there is little chance of spontaneous resolution of these gallstones. Teenagers tend to present in a similar manner to adults and are managed much the same way. Although plain radiographs are more useful in children than in adults, abdominal ultrasonography remains the most useful tool to document cholelithiasis. Safe access to the abdominal cavity is the first step to successful laparoscopic cholecystectomy, and the arrangement of secondary ports varies with the age and size of the patient. Choledocholithiasis can be managed laparoscopically in experienced hands, and endoscopic retrograde cholangiopancreatography plays a diagnostic as well as therapeutic role for this problem. Laparoscopic cholecystectomy has become the standard of care for all children in whom cholecystectomy is required.
