胰腺实性假乳头状瘤的诊治

目的 探讨胰腺实性假乳头状瘤的临床诊治.方法 回顾性分析2005年10月至2008年12月间收治的10例胰腺实性假乳头状瘤患者的临床资料.结果 10例患者均为女性,年龄11～39岁,平均24岁.中上腹部不适或疼痛为主要症状,4例体检触及腹部包块.B超、CT及MRI检查显示胰腺实性或囊实性占位.术前实验室检查无明显异常,肿瘤标记物正常.所有病例均接受手术治疗,胰腺头颈部肿块6例,胰体尾部肿块4例.手术方式:肿块切除3例,胰体尾切除3例(2例保留脾脏,1例联合脾脏、远端胃及部分结肠切除),节段性胰腺切除3例,胰十二指肠切除1例.术后2例发生胰瘘,经非手术治疗治愈,无其他外科并发症.切除的肿块长径约5.9 cm.平均随访时间19.2个月(8～42个月),所有患者均存活,无肿瘤复发转移迹象.结论 胰腺实性假乳头状瘤是临床少见的低度恶性胰腺肿瘤,手术切除预后良好.

Solid pseudopapillary tumors of the pancreas: diagnosis and treatment

Objective To summarize the experience in the diagnosis and treatment of solid pseudopapillary tumors of the pancreas. Methods Ten consecutive patients who underwent surgery with pathologically confirmed solid pseudopapillary tumors of the pancreas between October 2005 and December 2008 were retrospectively reviewed. Results All of the 10 patients were female and the median age at diagnosis was 24 years (range, 11 -39 years). Abdominal discomfort or pain were the most common presenting symptoms. 4 patients had palpable abdominal mass at physical examination. The tumors appeared on ultrasonography and/or CT, MRI as solid or cystic masses. The preoperative serum biochemical parameters and tumor markers level were within the normal range. All the patients underwent surgical treatment. The tumors were located in the head/neck (n = 6) or the distal part (n = 4) of the pancreas. The surgical procedures included enucleation (n=3) , distal pancreatectomy (n=3 , two with preservation of the spleen, one combined with splenectomy, distal gastrectomy and partial colectomy) , segmental pancreatectomy with pancreaticojejunostomy (n=3) and pancreaticoduodenectomy (n = 1). Pancreatic fistula (n = 2) was observed postoperatively and resolved with conservative treatment. The median resected tumor size was 5. 9 cm. All patients were alive and remained recurrence and metastasis free after a median followk-up of 19. 2 months (range, 8～42 months). Conclusions Solid pseudopapillary tumor of the pancreas was rare neoplasm occurred predominantly in young women with low malignant potential. Aggressive resection should be attempted and could result in excellent prognosis.
