目的探讨壶腹部肿瘤术前活检的诊断价值。方法回顾性分析2000年1月至2009年11月本院收治的53例壶腹部肿瘤患者的十二指肠镜检及活检资料。结果所有患者术前均行十二指肠镜检查并活检。术前活检病理结果 :腺癌20例(37.7%),高级别上皮内瘤变19例(35.8%),低级别上皮内瘤变13例(24.5%),炎性息肉1例(1.9%)。53例患者中47例(88.7%)行胰十二指肠切除术,6例(11.3%)行肿瘤局部切除术。术后病理结果为:腺癌46例(86.8%),类癌1例(1.9%),腺瘤恶变3例(5.7%),腺瘤伴上皮内瘤变3例(5.7%)。结论多数壶腹部癌分化程度高,肿瘤表层活检难以做出正确诊断,肿瘤定性需结合病变形态、大小,必要时行切除活检。 相似文献

腹腔镜超声在胰腺壶腹部肿瘤分期诊断和治疗中的价值 总被引:4,自引:0,他引:4
目的 评价腹腔镜超声技术(LapUS)在胰腺和壶腹部癌肿分期诊断和治疗中的临床应用价值。方法 自1996年12月~1999年12月连续对46例怀疑胰腺和壶腹部肿瘤病人进行腹腔镜和腹腔镜超声分期诊断。并与术前影像学检查、手术中发现及术后标本病理学检查进行前瞻对比研究。着重检查肿瘤范围、周围血管侵犯、周围淋巴结转移、浆膜浸润和肝、邻近脏器转移;对可疑病变和肿大的淋巴结进行腹腔镜超声引导下穿刺活检。判断肿瘤切除性。结果 46例病人中。LapUS发现肿块性病灶44例,2例阻塞性黄疸确诊为壶腹部结石嵌顿排除肿瘤。44例肿块性病变中41例为恶性肿瘤,3例为炎性病变,肿瘤诊断正确率为93.2%。本组未发生腹腔镜和腹腔镜超声检查有关并发症。结论腹腔镜和腹腔镜超声检查应列为重要的分期诊断工具,剖腹探查前常规应用可明显提高诊断正确率、完善肿瘤分期诊断和可切除性判断。可避免不必要的剖腹探查术。在微创外科诊治中具有重要的临床应用价值。 相似文献

超声内镜与CT对胰腺及壶腹部周围肿瘤的术前诊断价值 总被引:3,自引:0,他引:3
目的评估超声内镜(endoscopic ultrasonography,EUS)和CT对胰腺及壶腹部周围肿瘤的术前诊断价值。方法回顾性分析33例胰腺及壶腹部肿瘤患者术前EUS、CT资料,与手术探查及术后病理结果对照,从肿瘤大小、部位等角度筛选出影响EUS准确性的因素。结果 EUS在判断胰周脂肪浸润、胆管扩张、胰周脏器侵犯、血管侵犯等方面敏感性、特异性与CT的差异无统计学意义(P>0.05);EUS在胰管扩张及淋巴结转移方面的诊断价值优于CT(P=0.039和P=0.004); EUS判断胰周脂肪浸润和胰周脏器侵及的准确性与肿瘤大小有关(P=0.015和P=0.022),判断胰管扩张的准确性与肿瘤部位有关(P<0.001)。结论 EUS对胰腺及壶腹部周围肿瘤诊断的临床价值很高,结合CT检查有助于加强对患者术前评价的认识。 相似文献

壶腹部癌的发病率高于胆管下端癌,但远低于胰头癌。据统计,其发病率仅为胰头癌的1/12。近年,随着消化内镜的普及,壶腹部癌的发现率逐渐增加。与胆管下端癌及胰头癌比较,壶腹部癌的预后相对较好,手术切除率高,术后5年生存率为30%-70%,诊断和治疗有其独自的特点。 相似文献

壶腹部癌的诊断和治疗 总被引:2,自引:0,他引:2
Ampullary cancer is a relatively uncommon cancer,which is often considered to have a best prognosis among periampullary cancers.Preoperative endoscopic uhrasonography and transpapillary intraductal ultrasonography Call provide useful information not only for tumor staging but also for making therapeutic decisions,especially in patients who are appropriate for endoscopic papillectomy.Whipple resection and pylrus preserring panereaticoduodenectomy are considered to be the standard treatment for ampullary cancer.Although transduedenal ampullectomy is regarded as a less-invasive treatment compared with Whipple resection,it has a high morbidity and hish rate of cancer-cell remnant at the resected margin.Endoscopic papiilectomy may be the treatment of choice for selected cases of ampullary cancer. As to unresectable ampullary cancer,the performance of a biliary-enteric bypass is considered routine to solve obstructive ianndice.The decision as to whether to perform gastrojejunostomy in patients without obvious gastroduodenal obstruction secondary to the tumor remains controversial.We believe that prophylactic gastrojejunostomy should be performed routinely when a patient is undergoing surgical palliation for unresectable ampullary cancer. 相似文献

Staging and treatment for patients with pancreatic cancer. How small is an early pancreatic cancer? 总被引:11,自引:0,他引:11
Tsukasa Tsunoda Yasuhisa Yamamoto Masatoshi Kimoto Hiroyuki Imai Sueharu Iwamoto Seiji Kawasaki Kunihiro Kawashima Yoshiyuki Tadaoka Toshimitsu Majima Eishi Onuma Katsumichi Iki Tadahiko Kubozoe Toshifumi Eto 《Journal of Hepato-Biliary-Pancreatic Surgery》1998,5(2):128-132
To determine the tumor size that constitutes early pancreatic cancer, we reviewed and analyzed the English-language and Japanese
literature (a total of 25 publications) on small pancreatic cancers less than 2 cm in diameter and/or stage 1 cancers. Reports
on in situ carcinoma and intraductal carcinoma of the pancreas were also evaluated. The results were: (1) A total of 302 cases
of small pancreatic cancer less than 2 cm in diameter reported at separate institutions were pooled from 15 reports. The rates
for patients in stage I and those with no lymph node metastasis averaged 41.7% and 57.9%, respectively. The 5-year postoperative
cumulative survival rate (5Y-PCR) was less than 50% in almost all these reports. Similar data were shown in the 7 collective
reviews. (2) Another 33 cases of small pancreatic cancer of 1 cm or less in diameter were collected from three reports. The
rates for stage I tumor and 5Y-PCR at one institution with two reports were 100% and 100% and the rates in the other report
were 85% and 78%, respectively. (3) Twelve cases of in situ carcinoma and intraductal carcinoma of the pancreas were collected
from four reports. All of the patients were stage I and were alive with no evidence of tumor recurrence for periods ranging
from 6 to 78 months. Small pancreatic cancer less than 1 cm in diameter is better viewed as an early pancreatic cancer, and
in situ carcinoma and intraductal carcinoma of the pancreas with minimal invasion to the pancreatic parenchyma may be defined
as early pancreatic cancer, regardless of size.

Sixty-three patients who had undergone pancreatoduodenectomy for carcinoma of the ampulla of Vater were analyzed with respect
to tumor extent and prognosis. The postoperative mortality rate was 3% and overall survival rates 3 and 5 years after surgery
were 55% and 46%, respectively. pTNM stage did not reflect prognosis after resection in patients at stages 2 and 3, while
pancreatic invasion and regional lymph node metastasis clearly reflected prognosis after resection. Of the 26 patients who
had no pancreatic invasion, regional lymph node metastasis was seen in only 19%, whereas of the 37 patients with pancreatic
invasion, 62% exhibited lymph node metastasis. These factors were significantly correlated (P<0.001). Pancreatic invasion appeared to be an indirect indicator of regional lymph node metastasis. We conclude that, to
improve prognosis for patients with pancreatic invasion, extended resection including extended lymphadenectomy, is a preferable
additional procedure. 相似文献
