Most surgeons think of psoas abscesses as a very rare condition related to tuberculosis of the spine, but in contemporary surgical practice they are more usually a complication of gastrointestinal disease. A case note study was undertaken on all patients treated for psoas abscess at two large hospitals in the mid-Trent region over a 2-year period. All seven patients presented with pyrexia, psoas spasm, a tender mass and leucocytosis. The diagnosis was made on abdominal radiographs in one patient, CT scan in three, MRI in two, and ultrasound in one. Aetiological factors included Crohn's disease in three, appendicitis in two, and sigmoid diverticulitis and metastatic colorectal carcinoma in one each. Six patients underwent transabdominal resection of the diseased bowel, retroperitoneal debridement and external drainage of the abscess cavity. Percutaneous drainage was performed in one. Two patients had more than one surgical exploration for complications. There were no deaths and the hospital stay ranged from 8-152 days. Psoas abscess can be a difficult and protracted problem. Bowel resection, thorough debridement, external drainage and concomitant antibiotics are essential for psoas abscesses complicating gastrointestinal disease. Defunctioning stomas may be necessary. However, in some cases a multidisciplinary approach may be required, as psoas abscesses can involve bone and joints.

Psoas abscess (PA) is an infrequent clinical entity and presents diagnostic and therapeutic challenges. Six cases are reported concerning diagnostic and therapeutic considerations. Clinical diagnosis is difficult because of non-specific symptoms. The primary psoas abscess has no definite etiology and is spread by hematogeneous route from a distant occult site. The PA can also be secondary to gastrointestinal pathology through direct infection of adjacent structures. The most common causes are Crohn's disease, appendicitis, diverticulitis and carcinoma. Routine laboratory evaluation is seldom useful for localizing the disease process. Conventional radiological techniques are often unhelpful. Modern imaging diagnosis techniques such as ultrasound and computerized tomography have allowed for a refinement in both the etiologic diagnosis and the treatment by means of CT-guided or ultrasound-guided percutaneous drainage of the abscess, thus avoiding surgical drainage in many cases. Immediately on diagnosis of PA prompt treatment is necessary. Percutaneous drainage should be performed whenever possible and in case of failure, surgical drainage should be practiced as well as intestinal resection, whenever indicated.
