  A
  ) Invertogram showing that the dilator contacted the air column in the distal intestine and the air-fluid levels at 28 hours of age. (
  B
  ) Diverting sigmoid colostomy when the patient was 8 months old. (
  C
  ) Distal cologram showing the rectal atresia without any fistula with an ~1.5 cm atretic gap.

case_images: An upside-down invertogram was performed, and a Hegar dilator was passed through the anal opening, which revealed an air column in the distal intestine ( Fig. 1A ).  A diverting descending colostomy was performed on the second day of life ( Fig. 1B ). Before the operation, a distal colostogram revealed rectal atresia without any fistula, and the atretic gap length of the rectum was determined to be ~1.5 cm ( Fig. 1C ).
case_images: (
  A
  ) Intraoperative image showing the patient in a prone position with the pelvis elevated for the posterior sagittal approach. The patient exhibited normal perineum, genitalia, and a normally located anal opening. (
  B
  ) Exposure of the defect with a Hegar dilator in the distal pouch. (
  C
  ) The fibrous tissue separating the two rectal pouches (the incision asymmetry is due to the asymmetric position of the instrument). (
  D
  ) The upper pouch of the rectum is held with sutures and opened. (
  E
  ) A simple end-to-end circumferential anastomosis with interrupted long-term absorbable sutures.

case_images: The continuity of the rectum was established with circumferential anastomosis using interrupted absorbable sutures and a posterior sagittal approach ( Fig. 2A - E ).
