残胃癌是胃手术后较少见的一种并发病,是指良性疾病进行胃部分或次全切除后,在残胃内发生的癌。国内残胃癌至1984年报告158例,发病率为0.3—11%。本病可发生在残胃的任何部位,但以吻合口为最多见。Morgenstern报道1100例中,91%发生在胃肠吻合口部位。其次为贲门。大多数为进展期癌。其肉眼形态和组织学类型与胃癌基本相同。可见到肿块呈结节状、溃疡型、浸润型或仅见吻合口糜烂、粗糙不平或僵硬。其组织学类型以腺癌多见,其次为未分化癌。
Gastric stump cancer is a kind of concurrence that is rarely seen after gastric surgery. It refers to cancer that occurs in the residual stomach after partial or partial removal of the stomach. Domestic cadaveric cancer reported to 158 cases in 1984, the incidence rate was 0.3-11%. The disease can occur in any part of the residual stomach, but the most common is the anastomosis. Morgenstern reported that of the 1100 cases, 91% occurred in the area of anastomosis. Followed by tips. Most of them are advanced cancers. Its gross morphology and histological type are basically the same as gastric cancer. It can be seen that the mass is nodular, ulcerous, infiltrative, or can only see anastomotic erosion, rough unevenness or stiffness. Its histological type is more common with adenocarcinoma, followed by undifferentiated carcinoma.
