Summary

This study compared two ways to manage pain during and after colorectal surgery: a TAP block (an injection into the abdominal wall) versus epidural anesthesia (an injection near the spine). About 200 adults having elective colon or rectal surgery for cancer or diverticulitis took part. The goal was to see which method provided better pain control and patient satisfaction.
