Objective: To identify the clinical characteristics of abdominal myofascial pain syndrome and assess the effect of the sonography-guided trigger point injection in patients with abdominal myofascial pain syndrome. Method: Data of 53 patients (22 men, 31 women, average age 52.2±15.6) who had received sonography-guided abdominal muscle injection was analyzed. Abdominal myofascial pain syndrome was diagnosed according to Greenbaum’s criteria. Sonography-guided injection was done in the abdominal muscles. We investigated the level of patient satisfaction and whether current pain exists. Level of satisfaction was categorized into 5 levels: very good, good, moderate, poor, very poor. Results: Injection was done once in 39 (73.6%), twice in 11 (20.8%) and more than three times in 3 patients (5.6%). Most frequently injected site was upper-middle abdomen (16.4%) and second was right-middle part (15.5%). Mean duration of pain before injection was 34.4±70.9 weeks. Thirty eight of 53 patients were connected by phone call. Mean time interval between last injection and phone call was 11.5±3.7 months. In 28 patients (73.7%) pain was relieved and the number of patients who remain pain was 10 (26.3%). Conclusion: Abdominal pain without intra-abdominal pathology can be provoked from abdominal myofascial pain syndrome. Most common pain area was upper middle abdomen. Sonography-guided abdominal muscle injection may be effective
