RESULTSOf the nine patients who presented with ED, nearly two-thirds were infants (age range 3 months-5 years). Seven (77.8%) were male and two (22.2%) were female. The presenting symptoms were varied, with the most common being abdominal mass and bleeding per rectum. Descriptions of the patients' age and gender, clinical features, main investigations, types and sites of cysts, surgical procedures performed and complications observed are RESULTS A total of nine patients were managed during the study period. The patients' ages ranged from three months to five years. Four out of nine EDs were rectal duplications. Three EDs were of the cystic type, five were of the tubular type and one was a complex mixed anomaly. Patients presented with varied symptoms, with the two most common being the presence of an abdominal mass and bleeding per rectum. Diagnosis was mainly achieved based on magnetic resonance imaging and computed tomography, although Meckel's scan provided accurate diagnosis in three of the nine patients. All the cysts were resected without any major complications, and patients were event-free during the five-year follow-up. Table I. A total of four out of nine patients had rectal duplications, and a perineal mass was noted in one (11.1%) patient. One patient had infected wound discharge following drainage of a perineal abscess, while penoscrotal hypospadias was present in another. (2) Although ED may present at any age, a majority are also why EDs may pose as a diagnostic challenge. In the present study, none of the patients were diagnosed antenatally.
CONCLUSIONSome patients, however, had unusual symptoms -one patient presented with a nonhealing wound in the perineum that had previously been incised and drained due to suspicions of it being a perineal abscess, although a closer look at the surface would have revealed the presence of mucosa in the deeper part of the wound. Only one patient in our series had associated penoscrotal hypospadias. Such anomalies have been reported in up to 50% of patients, with vertebral defects being the most common.(1)EDs may be cystic, tubular or mixed (cystic and/or tubular).Although EDs usually communicate with adjacent parts of the gut, instances of completely isolated duplication cysts have also been reported. (6) We found various types of duplication cysts in our patients, including the cystic, tubular and complex mixed varieties. According to the literature, the ileum is the most common site of ED, whereas gastric and colonic duplications are rare, (4) and thoracoabdominal duplications are the most challenging. (7)(8)(9) In our series, the ileum was the most commonly involved site (n = 5), presenting as either an isolated lesion or a combination. However, contrary to the literature, which does not describe a high incidence of rectal involvement, (7,9,10) our series saw four cases (out of a total of nine) of rectal involvement. Also, there was a higher incidence of tubular ED (n = 5) in our study. Interestingly, one patient had a rare, complex duplication cyst that s...
