Objective: To review the results of parastomal hernia repair with a simplified technique of translocation of the stoma with no need for a midline incision.
Methods: A total of 405 radical cystectomies with creation of an ileal conduit were reviewed at our institution. The primary goal of the review was to determine the incidence of parastomal hernias in a large series of cystectomies and their management at our institution. Surgical correction of parastomal hernia was indicated in case of pain, discomfort, risk of bowel obstruction, and/or distortion of the abdominal wall. The simplified technique includes an elliptical incision around the stoma and dissection of the hernia's sac down to the level of the fascia. The sac is incised and the peritoneum is entered. The ileal conduit is thereafter mobilized to guarantee sufficient length. This is crucial to be able to transpose the conduit 5-10 cm superiorly and to obtain a tension-free ileostomy.
Results: Sixty-three patients (16%) presented during the follow-up after ileal conduit a palpable defect or bulge adjacent to the stoma. The review highlighted 19 patients (4.69%) who developed a parastomal hernia and underwent surgical repair. Four cases (21%) recurred at a median follow-up of 55 months. Recurrence was not found to be related to gender, age, body mass index, protein level, radiotherapy, adjuvant chemotherapy, or previous abdominal surgery on univariate analysis. Postoperative complications included one wound infection (5.2%) and one stomal necrosis (5.2%).
Conclusions: The technique herein proposed simplifies the management of parastomal hernia repair by avoiding a midline incision, which implies a reduction in surgical trauma with acceptable recurrence and postoperative complication rate.
