Scintigraphy with 99mTc-labeled anti-granulocyte antibodies (AGAb) was performed in 50 patients with suspected appendicitis. Sequential and static imaging as well as SPECT of the pelvis and abdomen was performed 2 h p.i. In all patients the diagnosis was confirmed either histologically or by long-term follow-up. 13 patients had histologically proven acute appendicitis. In 11 patients the appendix scan had been positive and in 2 patients the scan had shown no significant tracer uptake in the right lower abdomen. The remaining 37 patients turned out not to have acute appendicitis. 29 out of these patients had negative and 3 had positive scan findings. In 5 patients the scan was equivocal. Out of these patients 2 had pathologic findings on the left side of the abdomen which turned out to be acute diverticulitis in one patient and acute peritonitis in the other. The remaining 3 patients with unclear scintigraphic findings had no acute appendicitis. Scintigraphy with AGAb is fast and easy to perform and thus superior to cell labeling methods for diagnosing acute appendicitis. Sensitivity for the diagnosis of acute appendicitis was 85% with a specificity of 91%. Chronic or scarred non-granulocytic appendicitis--in which there is often no definite indication for surgery--was negative in our study except for two cases.

The activity of alpha-amylase was measured in isolated granulocytes, serum and urine of 35 patients with acute appendicitis. The measurements were performed before operation and on the 7th day after operation. Slightly increased activity of alpha-amylase was found in the serum and urine of 15 patients. On the 7th day after operation the activity of this enzyme reached normal value. The activity of granulocyte alpha-amylase was elevated in 22 patients. In 2 of them the increased activity still maintained on the 7th day after operation. Positive correlation between the serum and granulocyte alpha-amylase activities was found. These observations allow to conclude that granulocytes are the source of increased alpha-amylase activity in the serum of patients with acute appendicitis.

Scintigraphy with Tc-99m labeled antigranulocyte antibodies (BW 250/183 MoABs) was performed in 32 patients with suspected appendicitis. Abdominal imaging (planar/SPECT) was performed 2 hours after injection of the tracer. All patients also had surgery and a histologic examination of the resected tissue. Of the patients, 17 suffered from "acute appendicitis" and 12 had right positive scans (sensitivity = 70.6%). In 15 patients, acute appendicitis could have been ruled out, and in 11 of these cases the scan was true negative (specificity = 73.3%). The overall accuracy was 71.8% (23/32 cases). The use of Tc-99m antigranulocyte MoABs may overcome the problems associated with the Tc-99m HMPAO granulocyte and In-111 oxine approaches, which include nonspecific intestinal activity or the lack of timeliness. The use of Tc-99m labeled antigranulocyte antibodies is suitable as an emergency procedure and may play a role in the management of patients with suspected appendicitis.

We report here on the clinical courses of three cases of acute appendicitis during a period of myelosuppression after chemotherapy for acute leukemia. The patients were two boys and one girl with a mean age 11 years (range, 10-12). Two of the patients had acute myeloid leukemia (AML) in subtypes M1 and M2, while the third had acute lymphoblostic leukemia of subtype L1 (FAB classification). All patients had clinical features of fever, abdominal pain, and elevations of C-reactive protein. However, the typical peritoneal signs were blunted and developed transiently in two cases. All patients were diagnosed as having appendicitis with abdominal computed tomography scan (CT), and proceeded to appendectomy. With perioperative support utilizing antibiotics, antifungal agents, blood components, and granulocyte-colony stimulating factor, surgical intervention was successfully performed, and all patients were able to undergo chemotherapy courses shortly after surgery. Histological examinations of the appendectomy specimens showed infiltration of most of the lymphoid cells and a few neutrophils in the wall of the appendix. Enhanced CT was useful in diagnosing appendicitis, which needs to be considered in cases presenting with clinical symptoms such as described here. Because of a high mortality rate after appendix perforation, immediate surgical intervention with sufficient perioperative support should be performed.
