RESUMO
INTRODUCTION: Parastomal hernia repair is a real surgical challenge because of the high rate of recurrence. The Stapled Mesh Stoma Reinforcement Technique (SMART) is a keyhole-like technique in which the mesh is stapled to the fascia using a circular mechanical stapler. METHODS: A prospective study from January 2021 to February 2023 was conducted including all patients operated with the SMART technique. Primary endpoint was the recurrence rate during the follow-up. Secondary endpoints were reoperation, Surgical site Occurrence (SSO) and deep (mesh) surgical site infection (SSI) within 30 days postoperatively. RESULTS: Sixteen patients operated on SMART procedures were included. The mean follow-up was 11.3 ± 9.2 months. The SSO rate was 18.7% (n = 3). A seroma was drained radiologically (IIIa), one haematoma was evacuated surgically (IIIb) and one patient presented a postoperative lesion of a ureter after a parastomal Bricker's hernia repair. In addition, there was one death due to multiple organ failure (V). There was no SSI. The recurrence rate was 57.1% during the follow-up. CONCLUSION: This study shows disappointing results for this SMART technique, with a high recurrence rate.
RESUMO
INTRODUCTION: Surgical site occurrence (SSO) and surgical site infection (SSI) are common concerns with incisional hernia repair. Intraoperative drain placement is a common practice aiming to reduce SSO and SSI rates. However, literature on the matter is very poor. The aim of this study is to investigate the role of subcutaneous and periprosthetic drain placement on postoperative outcomes and SSO and SSI rates with incisional hernia repair. METHODS: A non-randomised pilot study was performed between January 2018 and December 2020 and included patients with elective midline or lateral incisional hernia repair with sublay mesh placement. Patients were prospectively included, followed for 1 month and divided into three groups: group 1 without drainage, group 2 with subcutaneous drainage, and group 3 with subcutaneous and periprosthetic drains. Drains were placed at surgeon's discretion. All patients were included in the enhanced recovery program. RESULTS: One hundred and four patients were included. Twenty-four patients (23.1%) did not have drains (group 1), 60 patients (57.7%) had a subcutaneous drain (group 2) and 20 patients (19.2%) had both a subcutaneous and a periprosthetic drains (group 3). SSO rates were significantly different between the 3 groups: 20.8% in group 1, 20.7% in group 2 and 50% in group 3 (p = 0.03). There was no significant difference in deep and superficial SSI rates between the 3 groups. Subgroup analysis revealed that adding a drain in direct contact with the mesh significantly increased SSO rate but did not influence SSI rate. Length of stay was also significantly increased by the presence of a drain, 3.1 ± 1.9 days for group 1; 5.9 ± 4.8 for group 2 and 5.9 ± 2.5 days for group 3 (p < 0.005). CONCLUSION: Drain placement in direct contact with the mesh might increase SSO rate. More studies are necessary to evaluate the actual benefits of drainage after incisional hernia repair.
