title: Meckel diverticulum: ten-year experience in adults.
abstract: OBJECTIVE
  Meckel diverticulum, a congenital gastrointestinal anomaly, is well studied in pediatrics, but less so in the adult population. At the Charleston Area Medical Center (CAMC), in addition to the removal of Meckel diverticula in symptomatic patients, diverticula are commonly removed when found incidentally during other procedures. We present our experience over the past ten years with this condition, unusual in the adult population.
  
  
  METHODS
  From 1992 to 2002 at the Charleston Area Medical Center, Meckel diverticula were removed from 47 patients older than 18 years of age. We reviewed the age, sex, indication for removal, pathologic findings, and perioperative complications of these cases.
  
  
  RESULTS
  Diverticula were removed most often from female patients (31 female, 66%; 16 male, 34%). The removal of the diverticulum was incidental in 35 patients (74.5%) and symptomatic in 12 (25.5% percent). Symptomatic patients presented with: obstruction (n = 4), acute bleeding (n = 1) and diverticulitis (n = 7). Female patients were significantly less likely than male patients to be symptomatic (4 of 31, 13% among females, and 8 of 16, 50% among males; P < 0.05). Heterotopic mucosa was identified in six patients, two of whom were symptomatic at the time of removal. Gastric mucosa was found in all six of the diverticula with ectopic mucosa, although one of the six had a mixed gastric and pancreatic cell population. One asymptomatic patient had a malignancy identified as a 1.5 cm carcinoid with no evidence of metastatic disease. An adenomyoma was found incidentally in one patient upon pathologic evaluation. Hospital complications that could possibly be attributed to removal of diverticula included two wound infections and two anastomotic leaks requiring exploration (8.5% morbidity). Complications were experienced by two asymptomatic females, one asymptomatic male, and a symptomatic male. There were no mortalities.
  
  
  CONCLUSIONS
  Meckel diverticulum is found infrequently in the adult population. Adults rarely become symptomatic, but symptoms that do arise are associated with significant morbidity. Complications directly attributable to diverticulum removal are uncommon; however, those that do occur are often life threatening. Therefore, incidental removal of asymptomatic diverticula, particularly in women, is not recommended.
