A case report: Common channel anomaly with vaginal agenesis and rectal stone after posterior sagittal anorectoplasty (PSARP)

Research output: Contribution to journalArticlepeer-review

Abstract

Introduction and importance: We reported a case of common channel anomaly complicated with vaginal agenesis and rectal stone, which is a long-term complication of PSARP, a combination of very rare conditions with high morbidity and especially difficult treatment. Presentation of case: A 15-year-old female presented with a chief complaint of cyclic abdominal pain. The patient had no history of menstruation before. Physical examination showed a common channel. The diameter of the common channel was approximately 1 cm and 0.3 cm in length. A sound (±2 mm thickness) was inserted to the small opening between the urethra and anal mucosa with the length of the canal 6 cm. At the end of the opening, a stone-like structure was felt. The management of this case was abdominal hysterectomy with right salpingectomy and stone evacuation. Discussion: Cloacal malformation is thought to be associated with vaginal agenesis since both malformations are considered to have a similar pathophysiologic background. Treatment can be performed using posterior sagittal combined with laparotomy approach. After surgery, patients will need a long-term follow-up since the conditions may be associated with many possible urologic and gynecologic comorbidities, including recurrent urinary tract infections, hematosalpinx, and vesicourethral reflux, including stone formation. Conclusion: Our case was considered one of the most complex common channel anomalies because it was complicated with a rare condition called vaginal agenesis and rectal stone after PSARP. A multidiscipline approach was necessary.
