A Case of Gastritis Associated with Gastric Capillariasis

This report is about the case of gastritis associated with capillariasis. The patient was a 52-yr-old Korean woman who occasionally ate raw fish and chicken. She complained of mild abdominal pain and nausea, but not diarrhea. An endoscopic examination revealed an exudative flat erosive change on the gastric mucosa of the antrum. She was microscopically diagnosed as chronic gastritis with numerous eosinophil infiltrations. The sectioned worms and eggs in mucosa were morphologically regarded as belonging to the genus Capillaria. This is the first case of gastric capillariasis reported in the Republic of Korea.     

Totally laparoscopic pancreaticoduodenectomy for locally advanced gastric cancer

Background  In patients having locally advanced cancer of the stomach with suspected tumor infiltration to the pancreatic head or the duodenum, a concurrent pancreaticoduodenectomy with gastrectomy is occasionally prerequisite to achieve a microscopically tumor-free surgical margin. Materials and methods  We present the first series of successful totally laparoscopic pancreaticoduodenectomy (TLPD) for advanced gastric cancer with suspected infiltration to the pancreatic head. Results  TLPD was successfully performed without adverse events during surgery and resulted in favorable short-term outcomes of three patients with locally advanced gastric cancer with suspected invasion to the pancreas. Conclusions  Although TLPD for locally advanced gastric cancer is a technically difficult challenging operation that requires careful dissection along the major vessels, intracorporeal tie sutures, and the placement of an external drainage tube into a narrow pancreatic duct, this procedure is technically feasible and safe in the hands of experienced surgeons. Long-term follow-up is mandatory to validate oncological outcome.

胃癌神经旁浸润的临床特征与预后分析

Objective To investigate the association between perineural invasion (PNI) and clinicopathological factors and the effect of PNI on overall survival in patients with gastric carcinoma.Methods A total of 178 patients with gastric carcinoma from January 2004 to May 2008 were analyzed retrospectively. Paraffin sections of surgical specimens from all the patients who underwent gastric resection were stained with laminin. PNl-positive was defined as infiltration of carcinoma cells into the perineurium or neural fascicles. The association of PNI with clinicopathologic features and prognosis of gastric carcinoma was studied. Results PNI was positive in 78 of 178 patients (43.8%). The proportions of T stage, lymph node metastasis and TNM stage were significantly higher in PNI-positive group than those in PNl-negative group (all P＜0.01 ). The PNI positive rate was correlated with the depth of gastric mural invasion and clinical stage. The overall survival in PNI-positive group was significantly lower than that in PNI-negative group by univariate analysis (P＜0.01). The mean survival of PNI-positive patients (28.6 months) was significantly shorter than that of PNI-negative patients (44.3 months,P＜0.01), which was also influenced by pN stage, pT stage, and clinical stage(P＜0.0l ). By multivariable Cox proportional hazards model of overall survival, the positivity of PNI appeared to be an independent prognostic factor (hazards ratio=2.257,95% CI: 1.268-4.019, P=0.006).Conclusions PNI is associated with the degree of malignancy in gastric cancer. PNI can be a candidate of new prognostic factor.     

残胃癌的外科治疗及预后分析

胃间质瘤63例临床分析

目的总结胃间质瘤（胃GIST）的临床病理及免疫组织化学（免疫组化）特征,探讨胃GISTs诊断与治疗的方法及影响其预后的因素。方法总结1997年1月至2007年5月北京大学第一医院普通外科收治的63例经手术治疗的胃GISTs患者的临床资料,并进行Flecther侵袭危险性分级和预后分析。结果B超、CT及内镜超声（EUS）对本组患者的术前诊断准确率分别为72．2％、81．0％和94．3％。F=6．065,P〈0．05;差异有统计学意义。CD117阳性率88．9％,CD34阳性率95．1％。开腹或腹腔镜行胃部分切除38例,近端胃大部切除4例,远端胃大部切除8例;全胃切除13例,其中联合胆囊切除3例,联合胰体尾及脾切除7例;联合左肝外侧叶切除1例,行D：淋巴结清扫12例（均无淋巴结转移）。全组病例1、3、5年生存率分别为96．4％、84．7％和71．7％。单因素分析显示,侵袭危险性分级和肿瘤大小是影响患者生存的因素（P〈0．05）;而性别、年龄、核分裂像、免疫组化表达情况、是否联合脏器切除以及是否行淋巴结清扫与预后元关（P〉0．05）。多因素分析显示,侵袭危险性分级是胃GIST的独立预后因素（P=0．041）。结论术前EUS诊断准确率最高。建议用Fletcher侵袭危险性分级方法来判断胃GISTs的生物学行为及其预后。     

腹腔镜辅助与开腹胃癌根治术的配对设计队列研究

目的:评价腹腔镜辅助全胃切除术(laparoscopic-assisted total gastrectomy,LATG)及D2淋巴结清扫术的可行性、安全性、肿瘤根治性及术后早期疗效。方法:回顾分析为32例胃癌患者行腹腔镜辅助全胃根治术的临床资料,以性别、年龄、体重指数、ASA评分、术前总蛋白、白蛋白、血红蛋白、术前是否接受新辅助化疗、UICC(1997)分期、肿瘤部位、病理组织学类型及Bormann分型为指标,用逐一配对法选择同期32例传统开腹手术作为对照,比较两组的手术安全性、术后恢复及肿瘤的根治性。结果:32例均成功完成腹腔镜手术,无中转开腹。27例施行LATG(D2),1例行腹腔镜辅助全胃联合胰体尾切除术(D2),5例行腹腔镜辅助姑息全胃切除术。腹腔镜组平均手术时间(220.78±44.34)min,开腹组(178.44±29.06)min(P<0.05)。腹腔镜组平均切口长度、术后肛门排气时间及进食时间分别为(5.50±0.57)cm,(3.63±1.04)d,(3.94±0.84)d,显著低于开腹组。腹腔镜组术后第1天白细胞及中性粒细胞计数分别增加(6.61±2.92)×109/L,(7.32±3.01)×109/L,第3天白细胞及中性粒细胞分别增加(3.99±3.83)×109/L,(4.48±3.94)×109/L,显著低于开腹组。腹腔镜组淋巴结清扫总数、第1及第2站淋巴结数分别为(26.41±13.71)、(17.13±9.13)及(9.22±8.16)枚,与开腹组差异无统计学意义。腹腔镜组切口感染率低于开腹组,肺部感染率高于开腹组,但差异无统计学意义;两组其他并发症及总的并发症发生率差异亦无统计学意义。术后近期随访效果良好。结论:LATG比传统开腹手术时间长,但能达到与开腹根治性全胃切除术(D2)相同的淋巴结清扫范围,且具有患者创伤小、术后急性期反应轻、术后康复快等优势,LATG安全、可行、微创。     

高迁移率族蛋白B1 mRNA在脓毒症大鼠脾脏中的表达

目的：探讨高迁移率族蛋白B1（HMGB1）mRNA在脓毒症大鼠外周免疫器官脾脏的表达规律及其与血清肿瘤坏死因子-α（TNF-α）、白细胞介素-6（IL-6）的关系。方法：采用盲肠结扎穿孔（CLP）方法制备大鼠脓毒症模型。83只大鼠随机分为正常对照组（10只）、盲肠结扎穿孔组（38只）,盲肠结扎穿孔丙酮酸乙酯治疗组（35只）。分别于CLP术后4、12、24、48、72h或CLP术后丙酮酸乙酯治疗12、24、48、72h活杀动物,留取脾脏组织和血清标本,用半定量逆转录-聚合酶链式反应（RT-PCR）技术检测脾脏组织HMGB1mRNA的表达规律,用放射性免疫方法检测血清TNF-α和IL-6的浓度。结果：HMGB1mRNA在正常大鼠脾脏组织有轻度表达,CLP术后表达显著增强（P〈0.05）。CLP术后24h和72h分别出现两个高峰。丙酮酸乙酯液治疗可显著降低CLP术后大鼠脾脏组织HMGB1mRNA的表达（P〈0.05）。CLP术后大鼠血清TNF-α和IL-6浓度显著增高（P〈0.05）,丙酮酸乙酯治疗可显著降低CLP术后大鼠TNF-α和IL-6的浓度（P〈0.05）。结论：HMGB1在脓毒症大鼠外周免疫器官脾脏的表达显著增高,并与血清TNF-α和IL-6等炎症因子的增高有重要关系;HMGB1参与了失控性炎症反应的发展过程。

典型内镜下表现可以准确预测散发性胃底腺息肉：一项针对47771例内镜检查的回顾性研究

背景 散发性胃底腺息肉（FGPs）是目前最常见的胃息肉类型。本研究旨在调查基于典型内镜下表现预测散发性胃底腺息肉的可行性。 方法 回顾性分析我院胃镜检查发现胃息肉样病变的患者,记录年龄、性别以及内镜和病理表现。结合内镜表现和病理结果,计算胃底腺息肉的阳性预测值,并比较不同亚组间的差别。 结果 47771例胃镜检查中共发现1220例胃息肉样病变的患者。病理证实347例为胃底腺息肉,其中79%为女性,仅检出6例（1.7%）伴低级别异型增生,未发现合并高级别异型增生和癌变。1220例胃息肉样病变的患者中具备典型胃底腺息肉内镜表现的有383例,进而通过病理学证实的有344例（阳性预测值为89.8%）,其余未能准确预测的39例经病理证实均为良性病变。分层分析显示,女性和男性组阳性预测值分别为274/310 (88.4%)和274/310 (88.4%),P=0.057;老年患者和青年患者组分别为255/282 (90.4%)和89/101 (88.1%),P=0.511;单发息肉和多发息肉组分别为211/240 (87.9%)和133/143 (93.0%),P=0.111。 结论 本研究证实了散发性胃底腺息肉的良性特征,而且不管患者性别、年龄和息肉数量,胃底腺息肉均可以根据典型内镜下表现得以准确预测。
