Cases Presented
Video Summary of Cases Presented
The January 2026 International Colorectal Web Meeting featured focused on complex cases of anorectal malformations and bladder duplications. Dr. Ahmed Mai from Qatar presented a case of an anechoic duplication colon in an 8-month-old girl, while Dr. Rosa Fonseca from Spain discussed a challenging re-operation for a patient with a complicated anorectal malformation. Dr. Bruno Martinez from Mexico City shared a rare case of bladder duplication with a stone, and Dr. Karen Castaneda from Mexico City presented a successful treatment of rectal atresia in a 1-year-old male. The meeting discussions highlighted the importance of thorough preoperative imaging, careful surgical planning, and close postoperative follow-up for these complex cases. Surgeons attending from various countries shared their experiences and recommendations, emphasizing the need for collaboration and continuous learning in global pediatric surgery.
Case 1. Cloaca with Duplication Colon
Ahmed Mai, M.D.; Sidra Medicine, Qatar
A complex case of an 8-month-old girl with anorectal malformation, duplication of the colon, and a solitary kidney was presented. The patient underwent a laparotomy, cystoscopy, and vaginoscopy, resulting in a diverting stoma. The moderators suggested a prone approach for the perineal procedure and advised against laparoscopy, emphasizing the importance of a perfect lateral position for the distal colostogram. They recommended resecting the thin, duplicated rectum and leaving the urethra intact, unless catheterization becomes problematic. The decision on whether to join the two colon segments or use them for future vaginal reconstruction was left open for discussion.
Case 2. Complicated Anorectal Malformation with Long-term Nonfunctional Colon
Rosa Fonseca Martín, M.D.; Hospital General de Castellón, Castellón, Spain
This complex case involved a patient with a cloaca, emphasizing the need for precise anatomical definition through imaging studies, including a clear X-ray of the sacrum, a detailed colostogram, and a cystogram to assess for reflux. The treatment recommendation was against transverse colostomies, advocating instead for a descending colostomy to allow for effective irrigation and a cleaner distal bowel. The importance of monitoring the patient for signs of puberty and potential hemiuteri was highlighted, along with the need for follow-up with a nephrologist because of tetrachordia and single kidney. The team also addressed the role of MRI in predicting future continence, noting that while it can provide anatomical details, it does not determine functional outcomes.
Case 3. Anorectal Malformation with an Infrequently Associated Urinary Tract Malformation
Bruno Martínez, M.D.; High Specialty Surgery Division, Pediatrics Hospital, SXXI, National Medical Center, IMSS, Mexico City, Mexico
This was a rare case of bladder duplication with a stone, which was successfully treated without removing the duplicated bladder.
Case 4. Male Patient, 1 Year Old, Referred as a Rectal Atresia Case
Karen Castañeda, M.D.; Hospital Infantil de Mexico, Federico Gómez, Mexico City, Mexico
A case of rectal atresia treated via a transanal approach, which was successfully managed with dilation. The conversation ended with a discussion of surgical techniques and the importance of considering urinary malformations in patients with anorectal malformations. Participants from multiple countries shared their experiences and insights, highlighting the global nature of the discussion.
