[Diagnosis and treatment of rectal injury during laparoscopic radical prostatectomy: Analysis of 7 cases].

Objective: To explore the risk factors and management principles of rectal injury during laparoscopic radical prostatectomy (LRP).

Methods: We retrospectively analyzed the clinical data on 7 cases of LRP complicated with rectal injury and treated in Huzhou Central Hospital from January 2010 to June 2021. Four of the 7 PCa patients were found with complete rectal rupture during LRP, of whom 2 were treated by laparoscopic rectal repair (LRR) and the other 2 by LRR + colostomy during surgery. Another case of rectal muscle injury also underwent LRR. Two cases of delayed rectal rupture were observed postoperatively and treated by colostomy + transrectal repair in the second-stage operation.

Results: The rectal injuries were found in the apex of the prostate in all the 7 cases, pathologically staged as pT2b��pT3b and with Gleason scores of 7��10. Postoperative follow-up lasted 2 to 18 months, during which the 5 cases of intraoperative rectal repair recovered well without complications, and of the 2 cases of postoperative rectal repair, 1 made a good recovery and the other 1 developed rectourethral fistula.

Conclusion: Rectal injury during radical prostatectomy tends to occur in the apex of the prostate and can be effectively managed by laparoscopic repair. Meanwhile, attention should be paid to the postoperative complication of rectourethral fistula.
