Open Access Method

The open or Hasson technique is a safe method of access, and is recommended in patients with previous abdominal surgery, if there is difficulty in the establishment of pneumoperitoneum with Veress needle, or for children and very thin patients.

However, just as with Veress needle access, bowel and vascular injuries have been described (7,8,16). Penfield reported an incidence of 0.2% complication rate among 10,840 open laparoscopies, including a 0.06% incidence of bowel injury (17). There are fewer reports of bowel injuries using Hasson's method of access than with the Veress needle technique. It is however useful for the laparoscopic surgeon to be proficient with both techniques.
