食管中段、下段癌根治术常采用胃食管弓上吻合.由于较大的胸胃,占据左侧胸腔,而造成患者术后一系列的不适.作者通过44例行食管胃主动脉弓上吻合者,采用随机分组对照的方法,分别进行了胃与食管的左胸和食管床途径行食管胃弓上吻合.通过术前和术后的动脉血气分析以了解二种术式对动脉血气的影响.结果表明:PO_2两组术前和术后相比,均有下降(P<0.01);但术后二组相比,食管床组优于左胸内组(P<0.05);而 PCO_2两组术前、术后的下降值,均无显著差异.
The esophageal mid- and lower-stage cancer radical operations often use gastroesophageal anastomosis. Due to the larger thoracic stomach, it occupies the left thoracic cavity and causes a series of discomforts after operation. The author adopted 44 cases of esophagogastric aortic arch anastomosis. In a randomized controlled trial, gastric and esophageal left breast and esophageal beds were used for esophageal and gastric bowel anastomosis. Preoperative and postoperative arterial blood gas analysis was performed to understand the effects of the two surgical procedures on arterial blood gas. : PO2 decreased in both groups before and after surgery (P<0.01), but compared with the two groups after surgery, the esophagus bed group was superior to the left intrathoracic group (P<0.05); There was no significant difference between the postoperative and postoperative decline values.
