无功能胰岛细胞瘤罕见,发生率约占胰岛细胞瘤的15%,因无内分泌紊乱症状,早期难以发现,多数病人因腹部发现包块就诊。我院自1981年1月至1992年6月收治15例,首发症状:腹部包块5例,腹部不适与包块5例,腹部疼痛、恶心、呕吐类似急性胰腺炎者3例,腹部不适与黄疸者2例。多数病人虽然接受过B超、CT、ERP等检查,但由于该病少见,对其临床表现及影像学所见缺乏认识,15例中4例曾在外院接受手术治疗,术前仅1例考虑为本病,术中仍有2例误诊。另11例在我院经多项检查,术前仍有4例未能确诊。现就其中3例诊治经验与教训报告如下。例1.女,34岁。以腹部胀痛、上腹部包块4年、
Non-functioning islet cell tumors are rare and occur in approximately 15% of islet cell tumors. Because there are no symptoms of endocrine disorders, they are difficult to detect in the early stages, and most patients are found in the abdomen with masses. In our hospital from January 1981 to June 1992, 15 cases were treated. The first symptoms were abdominal mass in 5 cases, abdominal discomfort and mass in 5 cases. Abdominal pain, nausea, vomiting were similar to acute pancreatitis in 3 cases, abdominal discomfort and There are 2 cases of jaundice. Although most patients received B-ultrasonography, CT, ERP, etc., but due to the rare disease, lack of understanding of its clinical manifestations and imaging findings, 4 of 15 cases had received surgery in the external hospital, only 1 case was considered before surgery. There are still 2 cases of misdiagnosis during the operation. Another 11 cases were examined in our hospital through multiple examinations. There were still 4 cases that were not diagnosed before surgery. We report on the experiences and lessons learned from these three cases. Example 1. Female, 34 years old. Abdominal pain, upper abdominal mass for 4 years,
