Diverting Loop Ileostomy: With or Without Rod

2014-08-27 03:20:01 | BioPortfolio


Diverting ileostomies are created to protect a rectal anastomosis or in situations with a risk of intestinal perforation. Currently, the application of a rod to hinder slippage of the loop is an established technique to perform a diverting loop ileostomy. However, various "rod-less" techniques have been described and are performed with similar success. The aim of this study is to determine, whether a modification (without rod) of the current standard method of protective loop ileostomy formation (with rod) could improve ileostomy specific morbidity. Secondary endpoints include stoma care, determinants of quality of life and stoma function.



For rectal anastomoses within 6 cm of the anal verge, leakage rates are up to 15%. Here liberal use of protective stomas is widely accepted. Fecal diversion by loop ostomy may also be performed after extended adhesiolysis with serosal lesions and risk of intestinal perforation, in patients with obstructing rectal tumours requiring neoadjuvant radio-chemotherapy or in patients with complex anorectal injuries or fistulas. Generally, diverting loop ileostomies are secured at skin level by means of a supporting device in order to prevent retraction of the loop ileostomy into the abdomen. Nevertheless, due to the supporting rod, difficulties may occur in applying a stoma bag correctly and leakage of feces onto the skin may occur even with correct eversion of the afferent limb. Despite easier application of stoma bags and therefore reduced risk of skin irritation, none of these alternative techniques are established. In various non-randomized studies rodless loop ileostomies were described with an overall morbidity between 3 and 39%. However definition of morbidity varies significantly in these studies and randomised controlled trials are missing so far.


The aim of this study is to determine, whether a modification (without rod) of the current standard method of protective loop ileostomy formation (with rod) could improve ileostomy specific morbidity. Secondary endpoints include stoma care, determinants of quality of life and stoma function.


The study is designed as multi-institutional, randomized controlled, two-armed study. Patients scheduled for a protective loop ileostomy and meeting the eligibility criteria will be randomized to creation of a loop ileostomy with or without sustaining rod.

Medical and Biotech [MESH] Definitions

Surgical creation of an external opening into the ILEUM for fecal diversion or drainage. This replacement for the RECTUM is usually created in patients with severe INFLAMMATORY BOWEL DISEASES. Loop (continent) or tube (incontinent) procedures are most often employed.

A subfamily of ligand-gated ion channel receptors that share a characteristic loop which is formed by a disulfide bond between two CYSTEINE residues. These receptors typically contain five subunits with the cysteine-loop occurring near an N-terminal extracellular domain.

CIRCULAR DNA that is interlaced together as links in a chain. It is used as an assay for the activity of DNA TOPOISOMERASES. Catenated DNA is attached loop to loop in contrast to CONCATENATED DNA which is attached end to end.

Na-K-Cl transporter in the ASCENDING LIMB OF LOOP OF HENLE. It mediates active reabsorption of sodium chloride and is inhibited by LOOP DIURETICS such as FUROSEMIDE; and BUMETANIDE. Mutations in the gene encoding SLC12A1 are associated with a BARTTER SYNDROME.

Head to tail array of covalently joined DNA sequences generated by concatenation. Concatenated DNA is attached end to end in contrast to CATENATED DNA which is attached loop to loop.
