Isolation of Mycobacterium bolletii from human omentum after laparoscopic gastric banding.

Mycobacterium bolletii infection with band erosion complicating laparoscopic gastric banding is reported. A 33-year-old man developed right upper quadrant pain and an epigastric discharging lesion 4 weeks after revision of gastric banding for morbid obesity. Investigation revealed band erosion with infection of the omentum and the abdominal wall. The band was removed and M. bolletii was isolated and identified after DNA sequence analysis. To the best of our knowledge, this is the first case in which M. bolletii was isolated from a human omentum after complicated gastric banding surgery.
