Abstract
INTRODUCTION: Subcutaneous face and neck emphysema secondary to colonic perforation is a rare complication of colonoscopy. Presentation may be complicated by pneumothorax and/or respiratory distress. Evidence limited to case studies. Therefore, no management consensus of these rarely reported cases exists.
METHODS: All cases published on PubMed between January 1(st) 2000-November 1(st) 2016 reporting subcutaneous face and/or neck emphysema after colonoscopy are included. Management is discussed with trends identified. We report a case of a patient undergoing routine polypectomy who developed subcutaneous emphysema of the face, neck and thorax with a pneumothorax and pneumoretroperitoneum.
RESULTS: 37 cases were found (mean age = 64.1 +/- 15.09 years). The majority (n=24) were managed non-operatively. Conservative and operative management had mean inpatient stays of 7.6 +/- 4.65 and 19.5 +/- 21.62 days respectively. Sixteen cases had a concomitant pneumothorax with nine (56.3%) requiring decompression. No mortalities occurred.
CONCLUSION: An understanding of anatomy heightens awareness of the rare complication of face and/or neck surgical emphysema, secondary to pneumoretroperitoneum and pneumothorax, after perforation of the colon during endoscopy. Management remains controversial with expectant conservative bowel rest with antibiotics and operative intervention equally described. Conservative management had a shorter inpatient stay but was more common in younger patients.
