Psoas abscesses complicating colonic disease: imaging and therapy.
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.
