Gut microbiota predicts severity and reveals novel metabolic signatures in acute pancreatitis

Washed microbiota transplantation via colonic transendoscopic enteral tube rescues severe acute pancreatitis: A case series

Background

Gut microbiota dysbiosis plays a significant role in the development of acute pancreatitis (AP). However, a recent randomized trial reported negative findings regarding the use of fecal microbiota transplantation (FMT) via the mid-gut tube in severe AP. The case series presents the feasibility of washed microbiota transplantation (WMT) as a new methodology of FMT and its delivery via colonic transendoscopic enteral tubing (TET) for severe AP.

Case series

We presented two cases of severe AP rapidly rescued using WMT via colonic TET. Symptoms related to severe AP and the acute physiology and chronic health evaluation-II score improved soon after WMT. In Case 1, bilirubin and infection indexes continuously decreased after the initial WMT and the patient was successfully weaned off the ventilator and recovered from multiple organ system failures (MSOF) within ten days. In Case 2, the patient's consciousness rapidly improved within one day after WMT, with normal bowel sounds and stable blood pressure without vasoactive drug maintenance. Both Case 1 and Case 2 completed follow-ups of seven months and twenty-two months, respectively, with no reports of new-onset diabetes.

Conclusion

WMT via colonic TET played a critical therapeutic role in rescuing severe AP cases. This is the first report providing direct evidence for the clinical value of targeting microbiota through colonic TET in rescuing severe AP.
