Abstract
BACKGROUND: A rectoseminal vesicle fistula (RSVF) is a rare complication after anterior or low anterior proctectomy for rectal cancer mainly due to anastomotic leakage (AL). Limited literature documenting this rare complication is available. We report four such cases and review the literature to investigate the etiology, clinical manifestations, and the diagnostic and treatment methods of RSVF in order to provide greater insight into this disorder.
CASE SUMMARY: Four cases of RSVF were presented and summarized, and a further 12 cases selected from the literature were discussed. The main clinical symptoms in these patients were pneumaturia, fever, scrotal swelling and pain, anal pain, orchitis, diarrhea, dysuria, epididymitis and fecaluria. Imaging methods such as pelvic X-ray, computed tomography (CT), sinus radiography, barium enema and other techniques confirmed the diagnosis. CT was the imaging modality of choice. In cases presenting with reduced levels of AL, minimal surrounding inflammation, and controlled infection, the RSVF was conservatively treated by urethral catheterization, antibiotics administration and parenteral nutrition. In cases of severe RSVF, incision and drainage of the abscess or fistula and urinary or fecal diversion surgery successfully resolved the fistula.
CONCLUSION: This study provides an extensive analysis of RSVF, and outlines, summarizes and examines the causes, clinical manifestations, diagnostic procedures and treatment options, in order to prevent misdiagnosis and treatment errors.
