| Abstract|| |
We present the case of an 82-year-old woman admitted in the intensive care unit with a septic shock caused by a liver abscess. She underwent an emergency laparotomy for abscess drainage and microbiological sampling. In the early postoperative period, she developed a massive subcutaneous emphysema (SE) extending from the abdomen to the head, without obvious cause. A surgical complication was suspected; thus, the patient underwent a second laparotomy which revealed a perforated peritonitis. SE is a rare presentation of perforated peritonitis, which should be known by critical care physicians in order to avoid a misdiagnosis of this life-threatening pathology.

| Introduction|| |
Subcutaneous emphysema (SE) is defined as the presence of extra-alveolar air in soft tissue, diffusing through fascial planes. The main causes of SE are dominated by soft-tissue infection, traumatic injuries with disruption of mucosal or cutaneous barriers, or alveolar rupture in case of brutal increase of the gradient pressure between alveoli and the surrounding interstitial tissue. In rare occasions, SE may occur after extraperitoneal colonic perforation following colonoscopy., However, this rare presentation of colonic perforation, particularly without suggestive medical history, may delayed the diagnosis of this life-threatening condition. Informed consent from the patient's family was obtained before writing this case report.
| Case Report|| |
An 82-year-old woman, with a body weight of 57 kg, with a medical history of treated arterial hypertension, was admitted to our intensive care unit (ICU) with the diagnosis of septic shock. First physical examination found a heart rate at 124/min and blood pressure at 80/45 mmHg without response after 1-L crystalloid fluid expansion. The patient had a polypnea at 28 cycles/min without other respiratory distress sign. The abdomen was tense and painful to the palpation. First laboratory blood test showed a hyperlactatemia-related metabolic acidosis with a pH at 7.21, a PCO2 at 24 mmHg, a bicarbonate level at 14 mmoL/L, and a lactate level at 9 mmoL/L. Abdomen and pelvis computed tomography (CT) scan with injection of contrast material showed a voluminous liver abscess [Figure 1, Panel A], consistent with the diagnosis of liver abscess-associated septic shock. Rapidly, the patient developed respiratory and hemodynamic failure with the need of mechanical ventilation, and continuous norepinephrine infusion up to 8 mg/h. An empiric broad-spectrum antimicrobial therapy consisting of piperacillin/tazobactam 4 g fourth a day and one injection of 8 mg/k of gentamicin (480 mg) was administrated for up to 3 weeks. The patient underwent an emergency laparotomy surgery for microbiological sampling and drainage of the liver abscess. In the early postoperative course, the patient demonstrated crepitation of the thoracic and cervical region consistent with the diagnosis of SE. A second CT scan confirmed the presence of massive SE extending from the abdomen to the head associated with a pneumoperitoneum [Figure 1, Panels B to D]. Of note, SE was found neither during the first physical examination at ICU admission nor on the first CT scan. There were no arguments, for upper airway injuries or pneumothorax. Because of the pneumoperitoneum, an early surgical complication was suspected; thus, the patient underwent a second emergency laparotomy which revealed a perforated lesion of the transverse colon. Five centimeters of colon was removed, and a colostomy was carried out. Unfortunately, despite surgery, the patient passed away few days later due to multiorgan failure.

| Discussion|| |
SE is caused by the passage of air beneath the soft tissue mostly after traumatic communication between close cavity containing air (sinuses, trachea, and alveoli) and underlying tissues. In a surgical context, SE may be an iatrogenic consequence of laparoscopy because of the diffusion of the insufflated CO2 gas through subcutaneous tissues. Few cases reported the presence of SE after colonic perforation complicating colonoscopy., Colonic perforation is a rare complication of colonoscopy with an incidence ranging from 0.04% to 0.7%. It can lead to SE only if the perforation involves the extraperitoneal colon. Accordingly, SE is exceptionally present in case of colonic perforation. Among mechanically ventilated and sedated patients, physical examination and interrogation is limited, thus identifying the origin of a SE is challenging for critical care clinicians. In our case, the cause of SE-related colonic perforation remained unknown. In ventilated patients, alveolar rupture due to mechanical ventilation-induced barotrauma must be ruled out. In our case, the CT scan did not reveal SE-associated pneumothorax or pneumomediastinum, arguing against this hypothesis. Our patient demonstrated SE within 12 h following the first laparotomy, consequently a surgical complication was suspected, but the surgeons did not report any difficulties during the first laparotomy surgery. Another explanation is that the perforation could result from colonic ischemia caused by the underlying septic shock. SE itself does not require specific treatment and its associated outcome mainly relies on the underlying etiology. Etiological diagnosis of SE remains the cornerstone of its management. In critically ill ventilated patients, alveolar rupture-related barotrauma is one of the main causes of SE, and its associated complications such as tense pneumothorax or pneumomediastinum must be ruled out. Exceptionally, SE is related to colonic perforation. This unusual presentation can mislead the clinician and delay initiation of the adequate treatment.
In conclusion, our case emphasizes that SE is an exceptional symptom of colonic perforation that should be suspected following recent laparoscopy or colonic procedure while ruling out more common causes such as alveolar rupture and barotrauma. Abdominal CT scan may facilitate diagnosis.
