title: Lower limb acute compartment syndrome after colorectal surgery in prolonged lithotomy position.
abstract: OBJECTIVE
  Acute compartment syndrome in patients undergoing prolonged colorectal procedures is uncommon but can have catastrophic consequences for the patient with the development of metabolic acidosis, myoglobinuric renal failure, Volkmann's contracture, limb loss, and death. The potential to produce long-term disability in a patient has important medicolegal implications, particularly if the complication is avoidable. Why only some patients develop acute compartment syndrome is not fully understood. The purpose of this study was to highlight current knowledge and suggested prevention strategies.
  
  
  METHODS
  A review of the relevant English language articles was performed on the basis of a MEDLINE search of the keywords: acute compartment syndrome, lithotomy position, reperfusion injury, and fasciotomy.
  
  
  RESULTS
  Different factors play a role: lithotomy position with or without head down, ankle and knee position, external compression for deep vein thrombosis prophylaxis, method of leg support, duration of surgery, and physiologic factors, such as gender, age, and body mass index. All efforts should be directed to prevent the establishment of acute compartment syndrome and there are accepted suggestions, such as limiting the time of leg elevation, positioning the leg below the atrium level, and monitoring postoperatively patients at risk. There is still debate on the intraoperative use of pulse oximetry to detect hypoperfusion and the appropriate use of sequential compression devices and antithromboembolic stockings.
  
  
  CONCLUSIONS
  Acute compartment syndrome is uncommon but cases have been reported after prolonged pelvic procedures in the lithotomy position and it is a preventable condition. More research is required to set clear guidelines on patient positioning during surgery.
