Abstract

トノメトリー法はトノメトリーカテーテルを用い,管腔臓器の二酸化炭素分圧(PiCO<sub>2</sub>)を計測する方法である。われわれは遊離空腸再建を行った16症例を対象に,自動測定器を用いたエアートノメトリー法で空腸内のPiCO<sub>2</sub>測定を行った。移植空腸のPiCO<sub>2</sub>値は空腸血流を良好に反映し,PiCO<sub>2</sub>値が持続的に上昇した症例で静脈血栓を認めた。本法は計数器がPiCO<sub>2</sub>を自動的に測定し,PiCO<sub>2</sub>値が数値で示されるため一貫性や客観性に優れている。またコメディカルスタッフによる経時的なチェックを行うことが可能であり,簡便性も備えた有効な血流評価方法と考えられた。

Since vascular trouble associated with free jejunum transplantation during the resection of hypopharyngeal cancer often induces severe complications, early detection and restoration of vascular disturbance is important. Various methods currently used for estimating blood flow are subjective or difficult to assess. We measured intramucosal carbon-dioxide partial pressure (PiCO<sub>2</sub>) of transferred jejunum continuously using an air tonometory method in 16 patients who underwent resection of hypopharyngeal cancer.<br>PiCO<sub>2</sub> of transferred jejunum almost paralleled arterial carbon-dioxide partial pressure (PaCO2). PiCO<sub>2</sub> elevation and its deviation from PaCO2 were observed with blood flow disorders such as vascular anastomosis. PiCO<sub>2</sub> evaluation is capable of quantitative and continuous assessment, and is an objective and effective method for early detection of vascular trouble of transferred jejunum.
