End Sigmoid Colostomy Reconstruction Using Purse-string Subcutaneous Suture via Extraperitoneal Route at the Site of a Previous Transperitoneal Loop Stoma.

We previously experienced two cases of end sigmoid colostomy reconstruction via the extraperitoneal route at the same site as the transperitoneal loop stoma. For an anterior rectus fascia, the transperitoneal route used closed intraperitoneal interrupted sutures and continuous sutures with barbed sutures. A new extraperitoneal route was established through the sutured anterior rectus sheath. Before reconstructing the end stoma, a subcutaneous purse-string with monofilament absorbable sutures tied to create an approximately 2.5 cm diameter was used. There were no early complications associated with the stoma. One year after surgery, a parastomal hernia was not defined. Using the presented technique, two cases were successfully recreated extraperitoneally at the same site's end stoma.
