Doxorubicin as Risk Factor for Fascial Dehiscence After CRS-HIPEC for Peritoneal Metastases.

BACKGROUND/AIM: Among postoperative complications, fascial dehiscence (FD) is registered in up to 10% of patients after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). This study aimed to evaluate the risk factors related to FD after CRS-HIPEC.

PATIENTS AND

METHODS

A retrospective analysis of a prospectively maintained database of consecutive patients who underwent CRS-HIPEC between 2015 and 2023 was performed. For each patient, risk factors for postoperative fascial dehiscence were identified using multivariate analysis.

RESULTS

During the study period (2018-2023), 217 patients were treated with CRS-HIPEC. The incidence of FD was observed in seven cases (3.2%), which were reoperated with direct fascial closure. In three cases, FD was associated with other grade III-IV complications. Body mass index, (BMI; p=0.024), doxorubicin-based HIPEC (p=0.005), and open technique (p=0.004) were identified as risk factors for FD in univariate analysis. Systemic chemotherapy, prior surgical score, and peritoneal cancer index (PCI) were not associated with an increased risk of FD. In multivariable regression analysis, doxorubicin-based HIPEC and open technique were confirmed as risk factors for FD.

CONCLUSION

Although FD is a relatively rare event after CRS-HIPEC, open technique and doxorubicin-based HIPEC were significant predictors of this complication. Specific fascial closure techniques and proper wound care should be considered in high-risk patients.
