Clinical Outcome After Close Rectal Ileo Pouch Anal Anastomosis for Colitis Ulcerosa(CU)

2014-08-27 03:14:07 | BioPortfolio


The purpose of this study is to investigate a new technique: Close Rectal Dissection (CRD) as restorative surgery for Ulcerative Colitis patients: the Close Rectal Ileo Pouch Anal Anastomosis (CR-IPAA). Clinical outcome and quality of life will be compared to the conventional Ileo Pouch Anal Anastomosis (C-IPAA) and the Ileo Neo Rectal Anastomosis (INRA).


Ulcerative colitis (UC) is characterized by recurring episodes of inflammation limited to the mucosal layer of the colon. The surgery rate after 10 years is 30%. After (sub)total colectomy with end ileostoma patients have a choice for restorative surgery. The conventional ileo pouch anal anastomosis (C-IPAA) is the gold standard of reconstructive surgery. This is al well established technique, but still carries a significant morbidity-rate. The recent studied ileo neo rectal anastomosis (INRA) has shown to reduce reservoir-related complications with a similar functional outcome, but is a very laborious technique. Therefore, we want to investigate an alternative technique: the Close Rectal Ileo Pouch Anal Anastomosis (CR-IPAA). The CR-IPAA is conducted in the nonanatomic perimuscular plane, resulting in a reduction of reservoir-related complications. After the close rectal dissection an ileo-anal pouch anastomosis will be constructed in a similar way. The close rectal dissection (CRD) is very laborious and has therefore never been developed extensively. But recent technical development of electrothermal bipolar vessel sealer (EBVS ) and ultrasound dissection have enhanced the CRD technique enormously. This brought along new interest in the CRD and justifies the research of its application.

Medical and Biotech [MESH] Definitions

Inflammation of the COLON that is predominantly confined to the MUCOSA. Its major symptoms include DIARRHEA, rectal BLEEDING, the passage of MUCUS, and ABDOMINAL PAIN.

Chronic, non-specific inflammation of the GASTROINTESTINAL TRACT. Etiology may be genetic or environmental. This term includes CROHN DISEASE and ULCERATIVE COLITIS.

Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.

An acute form of MEGACOLON, severe pathological dilatation of the COLON. It is associated with clinical conditions such as ULCERATIVE COLITIS; CROHN DISEASE; AMEBIC DYSENTERY; or CLOSTRIDIUM ENTEROCOLITIS.

A humanized monoclonal antibody that binds specifically to TNF-ALPHA and blocks its interaction with endogenous TNF RECEPTORS to modulate INFLAMMATION. It is used in the treatment of RHEUMATOID ARTHRITIS; PSORIATIC ARTHRITIS; CROHN'S DISEASE and ULCERATIVE COLITIS.
