Needle and trocar injuries in diagnostic laparoscopy under local anesthesia: What is the true incidence of these complications?

Laparoscopy is a relatively safe invasive procedure, but complications can occur, mainly related to Veress needle and trocar insertion. The rate of these complications is generally reported to be low, but the true incidence may be higher because of underreporting. We retrospectively studied the records of 2650 consecutive diagnostic laparoscopies performed by the same operator with the aim of assessing the true incidence and nature of these complications. Major complications occurred in 0.41% of cases and included bladder injury, bowel perforation, hemoperitoneum, and abdominal wall hematoma. Minor complications, including omental and subcutaneous emphysema, occurred in 1.58% of cases. Some of these resolved spontaneously, whereas others required surgical or medical treatment. We believe that all laparoscopic complications should be reported to a registry so that their potential risk can be quantified. Simply reporting complications as major or minor on the basis of the follow-up does not allow laparoscopists to understand their true incidence completely.
