Laparoscopic gastric banding comprises the systematic section of the pars flaccida and condensa of the lesser omentum. @entity99 ( @entity99 ) originating from the left gastric artery are located in the pars condensa of the lesser omentum. The aim of the present work was to study aberrant left hepatic artery rate in a prospective series of @entity1 operated on for morbid @entity28 using laparoscopic gastric banding. Between October 2001 and December 2003, a monocentric prospective study of 300 consecutive @entity1 operated on for morbid @entity28 was carried out. There were 245 @entity1 and 55 @entity1 with a mean age of 39+/-11 years. Preoperative weight was 123+/-18 kg, mean size was 166+/-9 cm and preoperative mean BMI was 44.5+/-5.6 kg m(-2) . Data were collected intraoperatively using a questionnaire submitted to the surgeon with @entity1 and @entity99 characteristics. The @entity99 were detected in 102 @entity1 (34%): one @entity99 in 100 cases (98%) and two @entity99 in two cases (2%). The @entity99 diameter was estimated by comparison using laparoscopic instruments. The median @entity99 diameter was 2 mm (0.5-13). A diameter >or=3 mm was observed in 47 @entity1 (16%) and <or=1 mm in 23 @entity1 (8%). The @entity99 presence and/or size were not correlated with @entity1 age, BMI or clinical characteristics. Using laparoscopic detection, @entity99 rate (34%) was higher than in the main previously reported series. This higher @entity99 rate was not related to the @entity1 age, weight or BMI but seems to be due to the great sensitivity of this approach.
