Another report from a large hernia centre in the US showed that in the first 300 transabdominal preperitoneal (TAPP) repairs 2 bowel injuries (and one bladder injury) were observed. Indeed, when these investigators changed the technique to a TEP repair they also observed 2 bowel injuries (and one bladder injury) in the first 300 TEP repairs. (www.ncbi.nlm.nih.gov/pubmed/11178763) Therefore bowel and vascular injuries during laparoscopic surgery are real but they are often under reported.
