Famlial Adenomateous Polyposis(FAP) is composed of hundreds of polyps lays
down the entire colon. Totally proctocolectomy has been standard treatment
modality due to 100% of malignity potential. There is no consensus for
rectoanal mucosectomy. Here we present our laparoscopic approach in FAP.
A fourteen-year-old girl admitted to gastroenterology clinic with the complaint of rectal bleeding and pain. Her aunt and mother were demised owing to malignity(FAP). Upper and lower endoscopy indicated that fundus, duodenum and colon have many adenomatous polyps with low to moderate dysplasia.
A median single incision, including the
umbilicus with three 5 mm ports, was performed. In order to be scar less other two
working ports was placed through the sides of planning to leave a penrose drain
and ileostomy. The dissection of cecum, colon, sigmoid and rectum were performed
with ligasure. Following adequate release and perineal sub-mucosal dissection, ileoanal
pull-through without pouch was performed. A penrose drain and ileostomy was placed as if
planned before. She began feeding postoperative 4th day, the drain
was taken out on postoperative 6th day. The histopathology was
revealed similar to preoperative, besides high-grade dysplasia in few specimens.
Surgical margin was intact. Control endoscopy was performed postoperative 1st
month. As histopathology was benign and no stricture was detected, ileostomy
was taken off. Although she is on Lopermid-HCl, defecation frequency is already
high (6-8/day) without soiling, with nighttime defecating. During follow up of
6 months she did well and happy with her incisions.
As a result, penrose drain and stoma localized working port assisted, single incision totally proctocolectomy, ileoanal pull-through, rectoanal mucosectomy and loop ileostomy in FAP is a safe and feasible technic. On the other hand, as our patients are around the adolescent age, to minimize the aesthetical anxiety of them, laparoscopy should be the choice of preference
