Abstract:
To avoid bowel perforation during deep pelvic biopsy, the authors describe a technique in which the iliacus muscle is distended by injecting it with a solution of lidocaine and saline. This muscle distention causes sufficient bowel displacement to allow safe advancement of biopsy needles as large as 14 gauge through the distended muscle belly to the region of interest.
