Surgery for Crohn's disease: new developments

Abstract

Background/aims: Crohn's disease is a chronic relapsing inflammatory bowel disease requiring surgery in a large number of patients. This review describes new developments in surgical techniques for treating Crohn's disease.

Results: Single-incision laparoscopic surgery decreases abdominal wall trauma by reducing the number of abdominal incisions, possibly improving postoperative results in terms of pain and cosmetics. The resected specimen can be extracted through the single-incision site or the future stoma site. Another option is to use natural orifices for extraction (i.e. transcolonic/transanal), but actual benefits of these procedures have not yet been determined. In patients with extensive perianal disease or rectal involvement, transperineal completion proctectomy is often feasible, thereby avoiding relaparotomy. By using a close rectal intersphincteric resection, damage to the pelvic autonomic nerves is avoided. In addition, the risk of presacral abscess formation is reduced by leaving the mesorectal tissue behind.

Conclusion: Minimally invasive surgery and associated techniques have become standard clinical practice in surgical treatment of patients with Crohn's disease. New developments aim at further reducing the hospital stay and morbidity, and improving the cosmetic outcomes.
