Transverse colon duplication with chronic constipation in adult

Duplication of the transverse colon in adults: a case report and literature review

Background

Duplication of the transverse colon is a rare gastrointestinal malformation. Its pathogenesis is still unclear, and it is extremely rare in adults. Patients often present with symptoms of tumor compression such as abdominal mass, abdominal pain, and constipation as the first manifestation.

Methods and result

A patient with a duplication of the transverse colon was admitted to the Department of General Surgery of our hospital. Laparoscopic exploration found a mass at the rear of the transverse colon near the splenic flexure, and the root was connected to the middle portion of the transverse colon.

Conclusion

Surgery is a radical treatment and reduces the possibility of perforation, bleeding, obstruction, and cancer.

Complete colonic duplication presenting as hip fistula in an adult with pelvic malformation: A case report

BACKGROUND

Alimentary tract duplication (ATD) is a rare congenital anomaly. Thus, a case of ATD with a complete colonic duplication isolated in the abdominal cavity with a fistula and multiple malformations is very distinctive. These characteristics show the variability of this disease and explain why it tends to be challenging to diagnose and treat.

CASE SUMMARY

A 25-year-old woman with a history of a fistula opening in her right hip since birth presented with the irregular discharge of foul fluid from the fistula and intermittent abdominal pain. Contrast-enhanced computed tomography and magnetic resonance imaging findings revealed a duplicated tube isolated in her abdominal pelvic cavity along with a pelvic malformation and double ureter. Right foot radiographic examination showed pes cavus. During surgery, the tube appeared to be an almost complete colonic structure and was verified to be connected to the fistula. All of the involved tissue and fistula were removed, and the defect in the pelvic floor was closed by suturing after surgery. After 8 mo, the postoperative follow-up has been uneventful.

CONCLUSION

ATD may be a differential diagnosis in sinus tract cases. Laparoscopy combined with open surgery is a viable treatment option.

Successful management of tubular colonic duplication using a laparoscopic approach: A case report and review of the literature

BACKGROUND

Alimentary duplication is a rare congenital disease with a reported incidence of 1 per 4500 persons, although the exact incidence has been difficult to ascertain. According to previous reports, the most common site of duplication is the ileum, and colonic duplication is rare. Due to different types and locations of the duplication, the manifestations are varied, which makes establishing an accurate diagnosis before surgery a challenge.

CASE SUMMARY

A 17-year-old female patient sought evaluation in our department with constipation and chronic abdominal pain for 12 years; she had difficulty defecating and had dry stools since she was a child. An abdominal computed tomography revealed two extremely enlarged loops of bowel full of stool-like intestinal contents in the left lower abdomen, which led us to consider the possibility of colonic duplication. A laparoscopic exploration was performed, which revealed a tubular duplicated colon that shared a common opening with the transverse colon. A left hemi-colectomy was performed with a side-to-side anastomosis. The pathologic results confirmed the diagnosis. At the 6-mo follow-up, the patient was doing well without constipation or abdominal pain.

CONCLUSION

Colonic duplication is a rare alimentary abnormality in adults. Due to the non-specific manifestations and low incidence, it is usually difficult to make an accurate diagnosis pre-operatively. Surgery is the mainstay of treatment, even though some patients are asymptomatic.
