小儿美克尔憩室及其合并症

经手术及病理证实小儿美克尔憩室７２例。出血、穿孔、腹膜炎、肠梗阻是美克尔憩室的常见并发症。憩室内迷走组织和憩室的形态特点是美克尔憩室的主要发病机制。强调应用９９ｍｍＴｃＯ－４同位素检查对本病的诊断价值；及时手术，采用包括憩室在内的肠段切除，端端吻合术为宜

Meckel''''s diverticulum and its complications in children

Seventy two cases of Meckel's diverticulum were treated surgically in recent four years. There were 61 boys and 11 girls with a mean age of 5.2 years. Of the 65 symptomatic patients, 31(43%) had rectal bleeding, 16(23%) suffered from bowel obstruction and 17(24%) peritonitis. Patients with diverticulitis(8 cases) had acute abdominal pain in the periumbilical region or in the right lower quadrant compatible with appendicitis. Ectopic mucosa was found in 47 cases(65.3%). Gastric(36 cases) and pancreatic(11 cases) were the most common ectopic tissues. A nuclear medicine Meckel scan was positive in 26 of 31 patients(84%). It is emphasized that 99mm TcO - 4 scintiphoto is more specific in diagnosis of the Meckel's diverticulum. The best choice of the surgery is resection of the diverticulum and end to end intestinal anastomosis.
