Abstract
An extremely rare case of multiple ileal mucosal diaphragms in a 63-year-old man is reported. Previously hehad undergone surgery for rectal cancer in our hospital in March 1989. Prior to that, there was no past history ofintestinal obstruction. He was readmitted due to postoperative ileus in September 1989, and underwentrelaparotomy. During adhesiolysis, multiple mucosal diaphragms were incidentally found in the proximal ileum.Each diaphragm had one orifice whose diameter ranged from pin-hole like to 10 mm. The majority of thediaphragms were removed by resection of 50 cm of the ileum with end-to-end anastomosis. Using tubes ofjejunostomy and cecostomy, smooth passage through the lumen of the residual small intestine was confirmedbefore anastomosis. Histologically the mucosal diaphragm contained hypertrophied muscularis mucosae. Con-genital jejuno-ileal stenosis in anadult is extremely rare, and as far as we investigated, only six cases have beenreported in the world.
