误诊为麻痹性肠梗阻的老年重症急性胰腺炎18例分析

目的 通过分析老年重症急性胰腺炎(SAP)的特点及病情转归.加强对老年SAP的认识.方法 收集2005年6月至2007年10月住院的18例误诊为麻痹性肠梗阻的老年SAP患者资料,并与同期住院的58例老年SAP进行比较.结果 误诊组首发症状分别为肠梗阻5例,腹胀纳差4例,恶心呕吐3例,慢性便秘3例,腹痛2例,腹泻1例;对照组分别为2例、3l例、9例、3例、11例、1例,其他1例.误诊组通过CT检查确诊13例,腹部超声及血清淀粉酶确诊分别为3例和2例;对照组通过CT检查确诊32例,腹部超声及血清淀粉酶确诊分别为15例和11例,两组相差显著(P<0.05).误诊组病死4例,其中男性2例,女性2例;对照组病死13例,其中男性3例,女性10例.结论 老年麻痹性肠梗阻患者应当注意SAP的可能,确诊有赖于腹部CT检查.

Clinical features of elderly patients with severe acute pancreatitis with misdiagnosis as having paralytic ileus

Objective The clinical features of elderly patients with severe acute pancreatitis (SAP) were atypical and these patients were often misdiagnosed as having paralytic ileus. The clinical presentations of elderly patients with SAP whose first diagnosis as paralytic ileus were analyzed. Methods 18 patients of elderly SAP who were misdiagnosed as having paralytic ileus were included and the clinical data were compared with 58 elderly patients with SAP. Results Among the misdiagnosis group, the first symptom onset were fleus, abdominal distension, vomiting, constipation, abdominal pain, diarrhea for 5, 4, 3, 3, 2, 1 case, respectively. Among SAP group, the first symptoms onset were 2, 31, 9, 3, 11, 2 cases, respectively. For misdiagnosis group, 13 cases were correctly diagnosed by CT scan, 3 cases by ultrasound and 2 cases by serum amylase test. For SAP group, 32, 15, 11 cases were diagnosed by CT scan, ultrasound and serum amylase, respectively (P < 0.05). 4 and 13 patients died in misdiagnosis and SAP group, respectively; among these 13 patients, 10 were female and 3 were male. Conclusions The elderly patients with paralytic ileus should consider the possibility of SAP, and CT scan was valuable for correct diagnosis.
