from the sample to have a more homogeneous group. The same physician did all of the gastric bypass procedures. Of the 64 packets given to the hand surgery patients, 25 were returned representing a 39% return, and 3 were dropped for incomplete data. The 22 remaining subjects included 12 patients who completed the McGill Questionnaire within 4 days of surgery, and 11 who were not recently postoperative but who were being treated at the hand rehabilitation clinic after their surgery for continued pain. Subjects The 55 volunteers who had either a gastric bypass procedure or hand surgery were divided into three groups. Group I consisted of the 32 morbidly obese patients who had gastric bypass. Group II comprised the 12 patients having hand surgery and completing the McGill within 4 days.
