Abstract:
Objective To investigate the clinical value of a newly designed surgical therapy for familial polyposis coli by severing the superior mesenteric artery&vein in order to make a complete lysis of the mesentery and an ileum pouch and the anal anastomosis within the entire muscular sheath of the rectum.Methods Six patients with familial polyposis coli(5 males and 1 female,aged 24-36 years)were admitted and underwent the procedure which was consisted of:(1)An incision was made in the left middle and lower parts of the rectus abdominis;(2)The greater omentum was retained and the large intestine was removed;(3)At the juncture of the sigmoid colon and the rectum,the muscular sheath was dissociated 0.5cm,the mucous membrane of the rectum was stripped in a revolving manner,the nourishing artery and vein in the membrane were exposed,and clamped and cut in sequence up to the anocutaneoue line;(4)The rectal mucous membrane was completely removed;(5)Under the right colonic artery,the superior mesenteric artery and vein were severed;(6)An N-,J-or W-shaped pouch was made in the ileum accordingly:(7)An anastomosis of the ileum pouch and the anal canal was made within the entire muscular sheath of the rectum,and a drainage was placed;(8)The mesostenium was fixed on the fight posterior abdomen,the small intestines were spread out to the right side,and the mesostenium was covered on the coarse surface of the colon bed:(9)A tube was placed in the left lower abdomen for a vacuum aspiration for 2 days after operation,combined with the suction drainage,to eliminate the pelvic effusions;and(10)The abdomen was closed.Results Patients were able to discriminate stools and flatus 3-7 days after operation.and the formed stools occurred 7-10 days after operation.Five patients were followed-up for 3-17 years,with averagely one defecation a day,with no night defecation and seepage.Urination was normal;In another one patient who underwent the procedure 4 months ago the defecation was twice a day,with no night defecation.All the 6 patients had normal autonomic nerve function and sexual function as well as normal defecation and urination,with no recurrence of polyposis coli or infection.The small bowel functions well with no ischemia related symptoms.Conclusion Cutting the superior mesenteric artery and vein and then making anastomosis of the ileum pouch and the anal canal within the muscular sheath of the rectum is a new surgical approach to familial polyposis coli.It is safe and significantly improves the patients' life quality.
