Initial Experience in the Use of Chimney Mesh for the Repair of Parastomal Eventrations in Our Hospital

Aim Parastomal hernias are one of the most common stoma complications. Although they are frequent, few are operated due to the low percentage of complications. Material and Methods This is a descriptive and retrospective study of the parastomal eventroplasties performed during 2023 using the chimney mesh by the Abdominal Wall Unit. The patients were evaluated after follow-up of their stomas by the General Surgery and Urology Service. Results 5 patients were operated, 4 men and 1 woman, mean age of 72 years (range: 65–78). The Body Mass Index was 28.016 (range: 23.46–32.37). Two patients had urostomies for bladder tumors, two patients had terminal colostomies for one rectal neoplasm and another for complicated diverticulitis, and one patient had both for bladder neoplasm with rectal infiltration that required Miles surgery. The surgery time for eventroplasty was recorded in 3/5 patients with a mean time of 160 min (range 165–180). In 2 patients laparoscopic cholecystectomy was performed for symptomatic cholelithiasis in the same surgical time. No intraoperative incidences were recorded during the procedures. In the postoperative period one patient required parenteral nutrition due to prolonged ileus that improved with conservative treatment (Clavien Dindo II). There were no major complications. The mean hospitalization time was 8.4 days (range 4–19) and during the outpatient follow-up we have not registered hernia recurrences. Conclusion The initial use of chimney meshes is giving good results in the selected patients, although the initial sample is small and the follow-up time is quite short to reach definitive conclusions.
