Complete tubular duplication of colon in an adult: a rare cause of colovaginal fistula

Sigmoid colon duplication with ectopic immature renal tissue in an adult: A case report

BACKGROUND

Colonic duplication is a rare congenital anomaly. Many types of heterotopic tissue were identified within the wall of duplication. However, studies of ectopic immature renal tissue (EIRT) involving colon duplication in an adult have yet to be reported.

CASE SUMMARY

A 23-year-old woman visited our hospital with symptoms of recurrent abdominal pain and chronic constipation. Image analysis via abdomino-pelvic computed tomography, Gastrografin contrast study, and colonoscopy showed a blind and dilated bowel loop filled with fecal material located on the mesenteric side of the sigmoid colon. We established a diagnosis of sigmoid colon duplication and decided to perform a laparoscopic investigation. Segmental resection of the sigmoid colon with duplication was done. Microscopically, the duplicated segment showed all three layers of the bowel wall and EIRT in the wall of the duplication. The postoperative period was uneventful and the patient was discharged nine days after the surgery without complications. She has been doing well 12 mo after the follow-up period.

CONCLUSION

A comprehensive histopathologic examination for ectopic tissues or tumors is mandatory after resection of colon duplication.

Transverse colon duplication with chronic constipation in adult

Gastrointestinal duplications are extremely rare congenital abnormalities having definite difficulties to be diagnosed preoperatively. Most of them are presented at the oesophagus and ileum and only involve colon from 4% to 18%. We illustrate a case report of an 18-year-old female patient with transverse colon duplication. There were symptom manifestations such as chronic constipation with flatulence accompanied with abdominal pain. We demonstrate this case report due to non-specific clinical presentation and some difficulties to form preoperative diagnosis. The patient underwent surgery. Tubular transverse colon duplication communicated with normal bowel in the proximal part was revealed. We performed transverse colon resection with duplication. The postoperative period was uneventful.

Hindgut Duplication: A Unique Case of Six Perineal Openings

Complete hindgut duplication is a rare and intriguing entity, often coupled with genitourinary abnormalities and neural tube defects. The diagnosis demands a thorough clinical exam and radiological workup. Timely recognition and expeditious treatment of these patients can lead to a better quality of life. We present a case of a 10-month-old female with complete hindgut duplication and associated genitourinary duplication treated with surgical intervention.
