“…Repeated Tc-99m scans overcome the suboptimal technique and pretreatment of H2 blocker facilitating the sensitivity of Tc-99m scans have been shown [7,11,14,18]. In this study, we repeated Tc99m scans in three patients with initially negative but eventually positive results which further confirms the value of repeated examinations.…”

Meckel's diverticulum (MD) has varied clinical manifestations and is a diagnostic challenge for pediatricians. This study investigates the clinical and diagnostic characteristics of MD in children with different presentations. We retrospectively reviewed the medical records of pediatric patients diagnosed with MD from 1988 to 2008. The data including the age, sex, clinical features, laboratory data, sensitivity of diagnostic methods, and pathological finding were recorded. These patients were classified into three groups: diverticulitis, intestinal obstruction, and intestinal bleeding. A total of 47 children (35 boys and 12 girls) with a median age of 5.6 years were enrolled and categorized as follows: diverticulitis (n = 12), obstruction (n = 12), bleeding (n = 21), and two diagnosed incidentally. Patients with intestinal obstruction were significantly younger than those with bleeding (3.7, 95% CI, 1.6-5.7 vs. 6.6, 95% CI, 4.5-8.7, P = 0.04). In the obstruction group, intussusception was found in eight of 12 patients, of whom 62.5% were aged older than 3 years. Heterotopic tissues were found in 46.3% of surgical specimens and more frequently existed in patients with bleeding than those with diverticulitis (P = 0.02) and obstruction (P = 0.047). Tc-99m scans yielded a diagnostic sensitivity of about 65% in bleeding patients. Repeated Tc-99m scans and red blood cell (RBC) scans can be good supplementary tools in Tc-99m scan-negative bleeding patients. In conclusion, manifestations of childhood MD are variable and may depend on the presence of heterotopic tissues and the patients' age. Tc-99m scans supplemented with RBC scans are appropriate to diagnose childhood MD with bleeding.

“…The fact that the diverticulum was demonstrated on delayed, rather than on early, images -where the stom ach was observed -may have accounted for a false-nega tive study. The latter has been described in cases where only a small amount of ectopic mucosa has been encoun tered, or in cases of inadequate blood supply to the diver ticulum, washout of activity by bleeding or inflammation and necrosis of the diverticulum [15][16][17][18][19][20], Ectopic mucosa was documented in the diverticulum removed from our patient. The diverticulum was inflamed, contained multi ple abscesses and was covered with fibrin.…”

Meckel’s diverticulitis in a patient with acute gastrointestinal bleeding is rarely diagnosed before surgery. The diagnostic dilemma of inflammatory abdominal symptoms and acute gastrointestinal bleeding in an 11-year-old child was resolved by a pertechnetate abdominal scan which demonstrated a Meckel diverticulum on delayed views which was not detected on early images. The preoperative work-up and the pathophysiology of the delayed uptake of this radiotracer are discussed.
