Q43.4

Clinical Causes: Developmental abnormality during embryogenesis, leading to incomplete or abnormal formation of the intestinal tract. Genetic factors that influence fetal development, although specific genes are not well-defined. Associations with other congenital anomalies, such as vertebral, renal, or neural tube defects. Environmental factors during pregnancy, such as teratogenic exposures, may play a contributory role, although evidence is limited.

Key Symptoms: Abdominal pain or discomfort Palpable abdominal mass Vomiting, which may be bilious in some cases Abdominal distension or swelling Digestive disturbances like diarrhea or constipation Occasional bleeding if the duplicated segment causes ulceration or erosion In asymptomatic cases, the duplication may be discovered incidentally during imaging or surgery.

Diagnosis Path: Ultrasound: May reveal cystic or tubular structures adjacent to normal intestinal loops. Computed tomography (CT) scan: Provides detailed images, helping to delineate the duplication and its relation to surrounding tissues. Magnetic resonance imaging (MRI): Offers high-resolution images without radiation exposure, useful especially in children. Barium studies: Contrast enemas or upper GI series can outline abnormal pouch-like structures or duplicated segments. Endoscopy: In some cases, direct visualization and biopsy may aid diagnosis.

Treatment Protocols: Resection of the duplicated segment along with adjacent normal intestine, followed by the reconstruction of the gastrointestinal tract. Enucleation: Carefully removing the duplicated tissue while preserving healthy bowel when feasible. Anastomosis: Connecting the remaining healthy sections of the intestine after excision. In some cases, minimally invasive laparoscopic surgery may be performed, reducing recovery time. Postoperative care focuses on preventing complications such as infection, leakage, or stricture.
