Gallbladder disease in patients 20 years of age and under.

Cholecystitis is uncommon in individuals under 21 years of age and, when present, usually is associated with pregnancy, sepsis, metabolic defects, hemolytic anemia, or hereditary disorders. Over the past 4 1/2 years, 92 patients 20 years of age and younger have been admitted to our institution with gallbadder disease. Of these patients, 88 were female and 76 were of Mexican-American origin. Only two of these individuals had associated hemolytic anemia. Seventy-six of these females had been pregnant at least once, and 57 were more than 10 pound overweight. Cholecystectomy was done on 88 of these patients, and cholelithiasis was found in 86. There were 28 explorations of the common bile duct, 18 of which were positive. This series represents an earlier onset of cholelithiasis in this population.

A clinical experience with intraoperative autotransfusion.

Utilizing a disposable unit, intraoperative autotranfusion was employed during surgery in 53 patients admitted to the Bexar County Teaching Hospital at the University of Texas Health Science Center at San Antonio. During the two-year period of study, 26 patients underwent surgery for major traumatic injuries, 8 for ruptured ectopic pregnancy and 19 for miscellaneous emergency or elective conditions. The indication for intraoperative autotransfusion was an anticipated blood loss of 1,000 ml or more. Contraindications for its use were colon injury or localized infection. Over 325 units of blood were salvaged and returned directly to these patients during surgery. One death related to the use of the autotransfusor unit was due to massive air embolism. Twenty other deaths were associated with severe injuries and irreversible shock requiring greater than 3,600 ml of both autologous and homologous blood. Eight of these patients demonstrated severe pancoagulopathies. In the remaining patients, clotting factors and plasma or urine hemoglobin levels were transiently abnormal. However, there were no clinically apparent bleeding defects or renal problems detected. Postoperative blood cultures were consistently negative. It is concluded that intraoperative autotransfusion, when properly employed, is a safe, practical and technically feasible procedure.
