Endorectal ileal pull-through for ulcerative colitis and polyposis in children

Role of surgery in pediatric ulcerative colitis

Pediatric ulcerative colitis (UC) has a more extensive and progressive clinical course than adult UC. Therefore, more aggressive initial therapies and more frequent surgical treatments are needed. The therapeutic goal is to gain clinical and laboratory control of the disease with minimal adverse effects while permitting the patient to function as normally as possible. Approximately 5-10 % of patients with UC require acute surgical intervention because of fulminant colitis refractory to medical therapy. Mucosal proctocolectomy with ileal J-pouch anal anastomosis is currently recommended as a standard curative surgical procedure for UC in both children and adults worldwide. This review will focus on the current issues regarding the surgical indications for pediatric UC, the technical details of procedures and results of most recent published series to take the most appropriate next step to improve the surgical outcomes and patients' quality of life.

History of and current issues affecting surgery for pediatric ulcerative colitis

Pediatric ulcerative colitis (UC) is reportedly more extensive and progressive in its clinical course than adult UC. Therefore, more aggressive initial therapies and more frequent colectomies are needed. When physicians treat pediatric UC, they must consider the therapeutic outcome as well as the child's physical and psychological development. Mucosal proctocolectomy with ileal J-pouch anal anastomosis is currently recommended as a standard curative surgical procedure for UC in both children and adults worldwide. This procedure was developed 100 years after the first surgical therapy, which treated UC by colon irrigation through a temporary inguinal colostomy. Predecessors in the colorectal and pediatric surgical fields have struggled against several postoperative complications and have long sought a surgical procedure that is optimal for children. We herein describe the history of the development of surgical procedures and the current issues regarding the surgical indications for pediatric UC. These issues differ from those in adults, including the definition of toxic megacolon on plain X-rays, the incidence of colon carcinoma, preoperative and postoperative steroid complications, and future growth. Surgeons treating children with UC should consider the historical experiences of pioneer surgeons to take the most appropriate next step to improve the surgical outcomes and patients' quality of life.

Sphincter-saving surgery for rectal and colorectal disorders

BACKGROUND

Restoration of intestinal continuity by anal anastomosis after sphincter-saving rectal excision is feasible from an oncological, technical and functional standpoint. We present our experience.

METHODS

The records of 223 patients with an anal anastomosis were reviewed. The anal anastomosis was performed hand-sutured transanally in 92 patients and double-stapled transabdominally in 131 patients. Coloanal anastomosis was performed in 39 patients and ileoanal pouch anastomosis in 184 patients.

RESULTS

Operation time, blood loss and admission times were considerably less after double-stapling anastomosis. Relevant complications occurred in 15% after coloanal anastomosis and in 35% after ileoanal pouch anastomosis, failure rate was similar (13%). Complication (7% vs 43%) and failure rate (2% vs 27%) were less after double-stapled anastomosis. Prednisone did not influence the failure rate whereas previous abdominal surgery did.

CONCLUSIONS

The double-stapling technique gives less complications and better results although effects of a learning curve are undoubtedly present in this series. The technique makes a temporary diverting ileostomy superfluous. The double-stapling technique is to be preferred for anal anastomoses.
