PURPOSE: Checking bowel viability is difficult but important during surgery for ischemic bowel disease or jejunal autotransplantation. We investigated the effectiveness of two-wavelength near-infrared spectroscopy (NIRS) to quantify tissue oxygen saturation (StO(2)), which can affect bowel viability during reconstruction of the cervical esophagus using a free jejunal graft. METHODS: Free jejunal autotransplantation was performed after resection of the hypopharynx, larynx, and cervical esophagus in 12 pigs. The arterial blood flow and StO(2) of the graft were measured before harvesting the graft and after reperfusion. We analyzed the measurement site of the graft and the anastomotic method as possible factors influencing StO(2). We also examined the relationship between the blood flow and StO(2) of the autograft. RESULTS: The StO(2) at the distal site of the graft was significantly lower than that at the midpoint of the graft (P < 0.05). There was a correlation between the blood flow of the graft artery, measured by the transonic volume flowmeter, and the StO(2) of the graft, measured by NIRS. CONCLUSIONS: Tissue oxygen saturation of the free jejunal graft can be safely and reliably measured with two-wavelength NIRS. Therefore, NIRS is a promising new method for evaluating the viability of the gastrointestinal tract. |
