Parastomal hernia prevention with an intraperitoneal prophylactic 3D-funnel mesh: review of the technique and middle-term results.

Abstract

Parastomal hernia (PH) stands out as a prevalent complication following end colostomies, significantly affecting patients' quality of life. Various surgical strategies, predominantly involving prophylactic mesh deployment, have been explored with variable outcomes. This study details our experience and mid-term outcomes utilizing a funnel-shaped mesh. A single-center, prospective, non-randomized, observational study examined consecutive patients undergoing colorectal surgery with end colostomy, incorporating a 3D-funnel mesh from January 2019 to December 2021 (PM group). A historical cohort of patients with end colostomy without prophylactic mesh served as the comparison (C group). Postoperative morbidity within 30days was documented, and clinical examinations and radiological tests were employed for parastomal hernia diagnosis during follow-up. Seventy-two patients participated, with thirty-four in the PM group and thirty-eight in the C group. The PM group experienced 16 postoperative complications, unrelated to the mesh, while the C group recorded 20 complications (p = 0.672). Median follow-up was 22.06months for the PM group and 63.18months for the C group. The PM group exhibited a lower parastomal hernia incidence during follow-up (8.8%) compared to the C group(68.4%) (p < 0.001). Prophylactic use of a 3D-funnel mesh appears effective in reducing parastomal hernia incidence in the short and mid-term, without an associated increase in postoperative morbidity.
