Pneumoperitoneum, pneumothorax, pneumomediastinum with massive subcutaneous emphysema: A rare presentation following transanal colonic barotrauma.

Iatrogenic colonic barotrauma is a well-documented entity, mostly due to endoscopic procedures. Compressed air pressure colorectal injury is less frequent, and the exact mechanism is not defined clearly to date. We present our experience of managing high transanal barotrauma to the colorectum in two similar cases presented with massive pneumoperitoneum, pneumothorax, and pneumomediastinum, a rare presentation in emergency departments, with an accident being the common etiology, where both the patients presented with massive abdominal distension and respiratory distress with diffuse subcutaneous emphysema. A huge amount of gas was noted in the peritoneal cavity on radiographs; the FAST examination was inconclusive and attributed to emphysema impeding the diagnosis. A big gush of air was noted during temporary pneumoperitoneum decompression and laparotomy. Multiple seromuscular tears with perforation in the transverse colon were identified and primarily repaired in the first patient, and the second one had perforation at the rectosigmoid junction, which was brought out as a stoma. The restoration of the stoma was done after ensuring adequate anal tone, with both patients doing well in the follow-up period.
