Evaluation of the Risk Factors for the Incisional Hernia Occurrence After Robot-Assisted Laparoscopic Radical Prostatectomy.

Objective: Our aim was to evaluate patient-related factors and compare the techniques used for surgical specimen removal [trocar extension (TE) and Pfannenstiel incision (PF)] in terms of incisional hernia (IH) occurrence in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALRP). Materials and Methods: The records of 219 patients who underwent RALRP in our clinic between November 2017 and March 2021 were analyzed retrospectively. Postoperative complication data and functional (continence and potency status) and oncological outcomes were recorded. Hernia type, location, and treatments applied were also noted. Results: After exclusion, complete data were available on 192 patients undergoing RALRP between the specified dates. The TE technique for removing the surgical specimen was performed in 135 patients, and the lower abdominal transverse incision technique (PF) in 57 patients. Preoperative patient- and tumor-related characteristics (age, body mass index [BMI], American Society of Anesthesiologists (ASA) score, T stage, and prostate size) were similar in both surgical groups. IH was detected in 16 patients (14 in the TE group and 2 in the PF group) (P = .156). Thirteen patients underwent surgery for IH, and three were followed up clinically. Conclusion: In our study, no statistically significant demographic or surgical technique-related factors were found to explain the occurrence of IH in patients who underwent RALRP for prostate cancer. It was observed that IH occurred more frequently in the cases where the surgical specimen was removed with the TE technique compared with the PF incision, but this result was not statistically significant. There was also no statistically significant difference between these two groups regarding oncological and functional outcomes in the early postoperative period.
