Objective To explore the significance of reserving the whole rectus muscle sheath and the technique of rotationally-striping the rectum mucous membrane in treatment of familial polyposis coli (FPC) for retaining the FPC patients’ urinating, defecating, and sexual functions to improve the life quality of the postoperative patients.Methods We reviewed the related operations performed by us for the FPC patients using the technique of rotationally-stripping the rectum mucous membrane to reserve the whole rectus muscle sheath in treatment of FPC. We evaluated the effectiveness of this kind of operation and the its effects on improving the patients’ life quality, especially on the young patients.Results After the rectum mucous membrane was completely stripped, the whole rectus muscle sheath had no residual membrane tissues left within the sheath; thus, the membrane secretion would not develop and the postoperative infection would not occur; therefore, the operation was successful. In addition, the long-term operative effect was good as proctopolypus and canceration would not take place. Conclusion The reservation of the whole rectus muscle sheath and the rotationally-striping method for the rectum mucous membrane in treatment of FPC can retain the postoperative FPC patient’s urinating, defecating, and sexual functions and can improve the patient’s life quality, especially the young patient’s life quality.

We evaluated the effectiveness of this kind of operation and the its effects on improving the patients’ life quality, especially on the young patients. Results after the rectum mucous membrane was completely stripped, the whole rectus muscle sheath had no residual membrane tissues left within the sheath; thus, the membrane bedding would not develop and the postoperative infection would not occur; therefore, the operation was successful. In add the long-term operative effect was good as proctopolypus and canceration would not take place. Conclusion The reservation of the whole rectus muscle sheath and the rotationally-striping method for the rectum mucous membrane in treatment of FPC can retain the postoperative FPC patient’s urinating , defecating, and sexual functions and can improve the patient’s life quality, especially the young patient’s life quality.
