BACKGROUND: @entity490 ( @entity490 ) is an important cause of chronic @entity490 . History and physical examination are critical to the diagnosis of @entity490 . Trigger point injection (TPI) using either a @entity479 or a local anesthetic or a combination of both is often used to treat @entity490 . AIM: To determine the efficacy of ultrasound-guided TPI and to determine the predictors of a successful response. METHODS: @entity1 who received ultrasound-guided TPI between July 2010 and June 2011 were surveyed. The primary outcome was determined using the Treatment Efficacy Questionnaire (TEQ). Electronic medical records were reviewed to determine @entity1 , @entity158 and TPI characteristics. Linear regression was used to determine the predictors of a successful response on the TEQ. RESULTS: Right upper quadrant was the most common site of @entity490 , and the median @entity158 duration was 12  months. @entity158 was rated as >8 (1-10 scale) by 57  % and 30  % described it as an ache. Narcotic use was reported in 38  %, and 73  % had a history of at least one abdominal surgery. Forty-four of the 120 (37  %) @entity1 met the criteria for responder on the TEQ. Compared to before treatment, 36  % reported being "significantly better" and 22  % "slightly better." Multiple linear regression analysis showed that higher somatization negatively predicted response. None of the other historical, examination or TPI characteristics were associated with response to the TPI. CONCLUSION: TPI can provide significant, long-term symptom relief in a third of @entity1 with chronic @entity490 attributed to @entity490 . Somatization was inversely related to the treatment success.
