[Technical prerequisites for performing controlled studies with the goal: postoperative quality of life after...

A study of 78 cases of gastrectomy in which two reconstruction procedures Roux-en-Y + pouch and interposition + pouch were compared and which is still in progress, yielded the following results: 1. It is possible to use both methods only with staplers and have few complications in a time-saving procedure. 2. A Roux-en-Y + pouch takes mean = 50 min; an interposition + pouch requires mean = 90 min (net time of reconstruction). 3. It is sometimes impossible for anatomical reasons to use an interposition + pouch. 4. The more complex procedure--the interposition + pouch--does not have a higher rate of complications. 5. Technical development permits controlled studies investigating the long-term target: quality of life.
