本文就活检或手术后病理证实的20例类癌作了临床分析,见于胃肠道者16例,其他部位类癌4例。临床局部症状表现腹痛、肠梗阻、腹块及消化道出血。出现类癌综合征有4例。20例全部嗜银染色阳性。因临床诊断十分困难,可借助内窥镜检查,在术前确诊。 This article made a clinical analysis of 20 cases of carcinoid confirmed by biopsy or pathology after surgery. It was found in 16 cases of gastrointestinal tract and 4 cases of carcinoid in other parts. Clinical symptoms include abdominal pain, intestinal obstruction, abdominal mass and gastrointestinal bleeding. There were 4 cases of carcinoid syndrome.
