Chronic refractory constipation (CRC) is an uncommon type of constipation. These children have persistent symptoms even after treatment with high dose laxatives, which may cause abdominal distension, vomiting, cramping and bloating. We conducted this study to assess the diagnostic and therapeutic role of anorectal myomectomy in children with CRC.

Materials and Methods:

This study includes 107 patients who fit the criteria of CRC. Complete bowel preparation with polyethylene glycol solution, enemas and antibiotics was carried out before surgery in all patients. The anorectal myomectomy was carried out under general anaesthesia with the patient in the high lithotomy position. The patients were followed up from 6 months to 13 years postoperatively. The success of myomectomy was based on the daily and complete passage of stools without the need for medication or enemas.


A total of 99 patients were included in the study, of which, 86 (86.86%) patients showed a good response to anorectal myomectomy. Of these, 32 patients had normal histology, 14 had histology suggestive of Hirschsprung's disease, 8 had hypoganglionosis, 10 had ultra-short segment Hirschsprung's disease and 22 had hypertrophic nerves with immature ganglia. Poor response was seen in 13 (13.13%) patients of whom 5 had normal histology, 5 had Hirschsprung's disease, 2 had hypoganglionosis and 1 had ultra-short segment Hirschsprung's disease.


Anorectal myomectomy is an effective and technically simple procedure in selected patients with CRC for both diagnostic and therapeutic purposes.
