[目的]观察康复新联合奥曲肽治疗消化道肿瘤介入治疗后黏膜损伤的疗效。[方法]采用康复新联合奥曲肽和单纯奥曲肽分别用于2组消化道肿瘤化疗患者,比较2组黏膜损害的发生率及程度。[结果]康复新联合奥曲肽较单纯奥曲肽治疗黏膜损害发生率低(P<0.05),程度也较轻。[结论]康复新可增加或协同常规黏膜保护的作用,价廉,有临床应用价值。 [Objective] To observe the curative effect of rehabilitation combined with octreotide on mucosal injury after interventional treatment of gastrointestinal tumors. [Methods] Rehabilitation combined with octreotide and octreotide alone were used in two groups of patients with gastrointestinal cancer chemotherapy, the incidence and extent of mucosal damage in the two groups were compared. [Result] The incidence of mucosal injury of rehabilitation combined with octreotide was lower than that of pure octreotide alone (P <0.05). [Conclusion] Rehabilitation can increase or cooperate with the role of conventional mucosal protection, low cost and clinical value.
