В Новой Зеландии хирурги впервые официально задокументировали феномен «анастомотического фырканья»

Ten days after surgeons removed part of his colon, a 90-year-old man in New Zealand spiked a fever. A chest X-ray, ordered because his doctors suspected pneumonia, came back showing a massive volume of free air trapped inside his abdomen. In almost any other circumstance, that image sends a patient straight back to the operating room. His team at Nelson Hospital did nothing of the sort. They watched him instead, and he went home two weeks later to live independently, as he had before. The reason they held off has now been written into the medical literature under a heading no journal had printed before. The case appears in the Journal of Surgical Case Reports under the title "Anastomotic fart." The X-ray That Normally Means the Bowel Has Given Way The patient had been dealing with recurrent sigmoid volvulus, a twisting of the lower colon, for about six months. Each episode had been untwisted endoscopically. As the episodes grew more frequent, he agreed, after talking it over with his family and the surgical team, to have the redundant loop removed. Surgeons resected roughly 30 centimeters of bowel through a muscle-splitting incision and hand-sewed a two-layer end-to-end join, known as an anastomosis. An endoscopic check during the operation showed the connection intact, with a negative leak test. Free air is not automatically abnormal after abdominal surgery. It usually clears within a week, though published imaging work has documented it lingering for 10 to 24 days. What changes the interpretation is the direction of travel. Air that is shrinking is healing. Air that appears out of nowhere on day 10 is something else. Recovery went slowly. By day seven he was still nauseated and vomiting, and a CT scan with rectal contrast showed a stalled bowel and a six-centimeter thickened, inflamed segment at the join. Crucially, the contrast passed beyond that segment without spilling anywhere, and there was no free air at all. He was started on intravenous nutrition while the inflammation settled. Three days later, everything changed on the imaging. The chest X-ray showed new right lower lobe consolidation and, alongside it, a large volume of free gas in the abdomen that had not been there 72 hours earlier. A repeat CT confirmed it, and again found no contrast escaping at the anastomosis. Why the Surgical Team Chose to Watch Instead of Operate New or expanding free air after a bowel resection is, in the authors' framing, almost always the signature of an anastomotic leak, and leaks of that kind usually get an operation. His numbers looked concerning: a temperature of 38.1 degrees Celsius, a white cell count of 15.3, and a C-reactive protein of 136 milligrams per liter. But the clinical picture did not match the scan. His blood pressure and heart rate stayed normal. His abdomen was distended yet soft, with no signs of peritonitis on examination. His inflammatory markers were already falling, down from 201 the day before. And on two contrast studies, nothing was leaking out of the bowel except air. After a discussion with the patient and his family, he declined further surgery. He was treated with a seven-day course of intravenous antibiotics and kept on intravenous nutrition. Over the following two weeks, his vital signs held, his abdomen stayed benign on repeated examination, his nasogastric output dropped, and his bowel movements returned. A repeat X-ray on day 17 of his admission showed the free air receding. He was discharged 24 days after the original operation. The Slang Term That Had Never Appeared in a Journal The phrase "anastomotic fart" is, according to the authors, in everyday use in general surgical departments to describe gas escaping through a fresh bowel join with little or no fecal spillage into the abdominal cavity. Surgeons have used it informally for decades, they write, but it appears nowhere in the published literature. Residents learn it by ear. That gap is the point of the paper. Phoebe Bardoul, Stephen French and Tom Burton argue that naming the phenomenon may help teams distinguish a transient gas leak from a full anastomotic disruption. They write that "Recognition of this phenomenon is essential to avoid unnecessary re-laparotomy in clinically stable patients." Their reasoning in this case rested on the absence of gross contamination combined with steady clinical improvement, which pointed to gas passing through rather than the join coming apart. The paper is indexed in the medical literature with the slang phrase as a formal keyword. What One Patient Can and Cannot Establish This is a single case report, the weakest tier of clinical evidence, and it cannot show how often conservative management works or which patients are safe candidates. The authors are explicit that management of anastomotic leaks remains inconsistent partly because definitions and terminology vary, and that the presence or absence of a diverting stoma changes the calculation. They point to newer work evaluating conservative management in selected patients as the basis for their proposal. They also draw a hard line. Leaks with actual fecal contamination still demand urgent intervention, and any conservative approach requires close serial examination and multidisciplinary input. Their proposal is narrower than it might sound: clinically stable patients whose leak appears to be gas only may reasonably be watched, even when the volume of free air looks alarming. For patients and families, the practical takeaway is not that free air is harmless. It is that surgeons weigh how a person looks against what a scan shows, and that a frank conversation about whether to reoperate is a legitimate part of care, particularly in the very old. Anyone recovering from bowel surgery who develops fever, worsening abdominal pain or vomiting should be assessed urgently. Key Questions Answered What actually happened to the patient? Ten days after a sigmoid colon resection, he developed a large volume of free air in his abdomen. His surgeons concluded that gas was escaping through the healing bowel junction without significant stool spillage, treated him with antibiotics and nutrition support, and avoided a second operation. What is an anastomotic fart? It is informal surgical slang for gas leaking through a bowel connection into the abdominal cavity with minimal or no fecal contamination. According to the authors, this case report is the first time the term has been described in published literature. Why is free air after bowel surgery usually an emergency? Some free air is expected after abdominal surgery and can linger for days. New or increasing free air after a bowel resection typically signals that the join has failed, which often requires a return to the operating room. Does this mean surgeons should stop reoperating for suspected leaks? No. The authors stress that leaks involving fecal contamination still require urgent intervention, and that conservative management demands repeated examination and team input. How strong is this evidence? It is a single patient case report. It illustrates a possibility and names a phenomenon, but it does not establish how safe or how widely applicable conservative management is. Who was involved and where? The case was reported by Phoebe Bardoul, Stephen French, and Tom Burton of the Department of General Surgery at Nelson Hospital in Nelson, New Zealand. Published by Medicaldaily.com
