Non-coated versus coated mesh for retrorectus ventral hernia repair: a propensity score-matched analysis of the Americas Hernia Society Quality Collaborative (AHSQC)

Hernia Mesh Complications: Management of Mesh Infections and Enteroprosthetic Fistula

The potential consequences of mesh infection mandate careful consideration of surgical approach, mesh selection, and preoperative patient optimization when planning for ventral hernia repair. Intraperitoneal mesh, microporous or laminar mesh, and multifilament mesh typically require explantation, whereas macroporous, monofilament mesh in an extraperitoneal position is often salvageable. Delayed presentation of mesh infection should raise the suspicion for enteroprosthetic fistula when intraperitoneal mesh is present. When mesh excision is necessary, the surgeon must carefully consider both the risk of recurrent infection as well as hernia recurrence when deciding on single-stage definitive reconstruction versus primary closure with delayed reconstruction.

Short-term outcomes of robotic inguinal hernia repair during robotic prostatectomy - An analysis of the Abdominal Core Health Quality Collaborative

BACKGROUND

Concomitant robotic-assisted laparoscopic prostatectomy (RALP) and robotic inguinal hernia repair (RIHR) has been reported. Nevertheless, data on its safety is lacking and some surgeons avoid performing both operations concurrently due to the potential risk of mesh related complications in the setting of a fresh vesicourethral anastomosis. We aimed to investigate differences in 30-day outcomes between patients undergoing RALP+RIHR and those undergoing RIHR alone.

METHODS

Patients who have undergone concomitant RALP and RIHR with 30-day follow-up available were identified within the Abdominal Core Health Quality Collaborative. Using a propensity score algorithm, they were matched with a cohort of patients undergoing RIHR alone based on confounders such as body mass index, age, ASA class, smoking, hernia size and recurrent status and prior pelvic operation. The groups were compared for 30-day rates of surgical site infection (SSI), surgical site occurrences (SSO), surgical site occurrences requiring operative intervention (SSOPI) and hernia recurrence.

RESULTS

24 patients underwent RALP + RIHR and were matched to 72 patients who underwent RIHR alone (3:1). Median age was 64 years, 33% were obese and 17% smokers. No significant differences were found on 30-day rates of overall complications (21% RALP + RIHR vs. 15% RIHR, p = 0.53) and surgical site occurrences (12% RALP + RIHR vs.11% RIHR, p = 0.85). No patient in the RALP + RIHR group had a 30-day SSI, SSOPI or early recurrence.

CONCLUSION

RALP+RIHR appears not to result in increased rates of wound complications, overall complications or early recurrence when compared to patient undergoing RIHR alone. Prospective, controlled studies with larger number of patients are needed to confirm our findings.

Are perioperative outcomes in cancer-related ventral incisional hernia repair worse than in the general population? An Abdominal Core Health Quality Collaborative (ACHQC) database study

PURPOSE

Patients with a history of cancer-related abdominal surgery undergoing incisional hernia repair (IHR) are highly heterogenous and increasingly prevalent. We explored whether cancer surgery should be considered an independent risk factor for worse IHR perioperative outcomes.

METHODS

Patients undergoing IHR between 2018 and 2020 were identified within the Abdominal Core Health Quality Collaborative (ACHQC). Regression models were used to assess associations between cancer operation history and 30 d surgical site occurrences-exclusive of infection (SSO-EIs), surgical site infections (SSIs), reoperations, time to recurrence, and quality of life (QoL) scores. Cancer cohort subgroup analysis was performed for operative approach and mesh location.

RESULTS

8019 patients who underwent IHR were identified in the ACHQC, 1321 of which had a history of cancer operation. Cancer cohort patients were more likely to be older, males with a higher ASA status and lower BMI, and have longer and wider hernias (p < 0.001). After adjusting for confounding, the cancer cohort was less likely to experience SSO-EIs (OR 0.74, 95% CI 0.59-0.94 p = 0.0092) and showed lower odds of SSIs, reoperations, and recurrence (SSI OR 0.7, 95% CI 0.47-1.05, p = 0.0542; reoperation OR 0.66, 95% CI 0.37-1.17, p = 0.1002; recurrence OR 0.8, 95% CI 0.63-1.02, p = 0.08). There was no difference in postoperative QoL scores between cohorts. There were also no differences in perioperative or QoL outcomes within the cancer cohort based on operative approach or mesh location.

CONCLUSION

These data show no evidence that history of cancer operation predisposes patients to worse incisional hernia repair perioperative or quality of life outcomes.
