Healing of Stoma Orifices: Multicenter, Prospective, Randomized Study Comparing Calcium Alginate Mesh and Polyvidone Iodine Mesh

The aim of this multicenter, randomized, prospective study was to reveal a difference in terms of a guided healing period in the case of stoma orifices after reestablishing digestive continuity by comparing an alginate mesh with a polyvidone iodine mesh. Between April 2004 and September 2005, a total of 73 patients were randomized into two groups: A (alginate mesh) and M (polyvidone iodine mesh). The groups were comparable for demographic data, indications for and the type of stoma, and perioperative data. The main evaluation criterion was percentage healing at the 28th postoperative day (D28); and the secondary criteria were healing time, rate of infectious complications, and number of dressing changes applied. The mean percentage healing at D28 was 91% in group A and 87% in group M (p = 0.49). The mean healing time was 31 days in group A and 32 days in group M (p = 0.80). One parietal abscess (3%) occurred in group A (p = 0.37). The mean number of meshes used was 13 +/- A 5 in group A and 18 +/- A 8 in group M (p < 0.005). The use of an alginate mesh for guided healing of stoma orifices after reestablishing digestive continuity allows effective healing within a normal period of time with a lower number of meshes.
