BorrmannⅣ型胃癌的临床特征和外科治疗

目的探讨BorrmannⅣ型胃癌的临床特征和治疗方法。方法回顾性总结29例BorrmannⅣ型胃癌的临床资料,分析本型胃癌的临床表现、病理特点以及手术治疗的特殊性。结果全部患者均有上腹饱胀、隐痛不适、食欲不振,同时伴有明显的进行性消瘦,短期内体重明显减轻等临床症状。术前病理确诊为本型胃癌者24例。5例患者胃镜诊断为浅表型胃炎。获根治性切除22例,姑息性远侧胃切除者3例,放弃手术者4例。其1、2、3年生存率分别为38.9%、8.3%、0%。结论(1)BorrmannⅣ型胃癌是一种恶性程度极高的胃癌,其具有独特的生物学特性,治疗效果差,生存期短,预后不佳。(2)对BorrmannⅣ型胃癌应强调以根治性全胃切除和联合脏器切除为主的综合治疗方法。     

Retrospective review of the preoperative biliary and gastrointestinal evaluation for gastric bypass surgery

BACKGROUND: The purpose of this study was to analyze the frequency and results of preoperative biliary and gastrointestinal (GI) evaluation of patients undergoing Roux-en-Y gastric bypass (RYGB). METHODS: Retrospective review of the preoperative evaluation of 144 consecutive RYGB patients. RESULTS: Cholecystectomy had already been performed in 43 (30%) patients; 22% of those patients with an intact gallbladder had cholelithiasis. Ten patients (7%) had an upper GI x-ray (UGI), and 94 patients (65%) had an esophagogastroduodenoscopy (EGD). Abnormalities were found in 40% of the UGIs and 84% of the EGDs. A total of 96 patients (67%) were tested for Helicobacter pylori; 11% were positive. Twenty-one patients (15%) underwent preoperative colonoscopy; 48% were abnormal, but most of the abnormalities were not clinically significant. Three patients had barium enema x-ray, which was normal in all cases. CONCLUSIONS: The preoperative biliary and GI evaluation of bariatric surgery patients should include a routine ultrasound of the gallbladder. Routine preoperative EGD will detect a significant number of abnormalities that should be treated, but should rarely alter the bariatric surgical procedure or result in denial of bariatric surgery. Many abnormalities will be asymptomatic. Patients should be routinely screened for H. pylori and, if positive, treated before bariatric surgery. Lower GI evaluation should be performed selectively based on the patient's symptoms, physical findings, and guidelines for colorectal cancer and polyp screening.     

128例老年胃癌患者围手术期临床特点分析及护理对策

目的：提高对老年胃癌患者围术期护理的认识。方法：对128例≥65岁胃癌患者与同期〈65岁212例胃癌患者围术期各方面资料进行对比分析。结果：≥65岁组术前合并症多，全胃及联合脏器切除比例高、创伤大，术后非手术相关并发症多，患者文化水平较低，社会支持水平低。结论：对老年胃癌患者应重视术前的全面评估和充分准备，争取和利用患者的社会支持系统，采取灵活多样的形式进行健康教育，术后重视呼吸系统、心血管系统并发症及手术相关并发症（吻合口瘙、胃排空障碍、胰腺炎、胸腔积液或腹腔积液等）的预防和护理。     

ENDOSCOPIC MANAGEMENT OF A DIEULAFOY‐LIKE LESION IN A DUODENAL DIVERTICULUM

We present a 70‐year‐old man who had two episodes of melena during the preceding 8‐year period. He had a Dieulafoy‐like lesion in a diverticulum in the third portion of the duodenum. While emergency endoscopy revealed neither apparent blood nor clots around the diverticular orifice, there was a non‐bleeding vessel in the fundus of the diverticulum. The vessel ceased bleeding after argon plasma coagulation and, since then, the patient has not experienced bleeding. In cases of gastrointestinal bleeding of obscure origin, duodenal diverticulum should be considered as a possible source of bleeding, even when endoscopy discloses no apparent bleeding.     

胃癌全胃切除术后消化道重建方式的选择

目的：探讨全胃切除术后较理想的消化道重建方式。方法：对近6年来122例施行全胃切除术患者的临床资料进行回顾性分析。全胃切除后消化道重建分别采用全胃切除术后消化道重建Orr式Roux-en-Y食管空肠吻合术、P型空肠袢食管空肠Roux-en-Y吻合术和远端空肠反口贮袋的Roux-en-Y食管空肠吻合术。结果：3种术式在食后烧灼感、进食量、进食次数、体重下降、倾倒综合征、血红蛋白、白蛋白等指标的比较，无明显差异（均P>0.05）。P型空肠袢食管空肠Roux-en-Y吻合术组所用手术时间显著多于Orr组及反口组（P<0.05）。反口组的贮袋大小及半排空时间显著优于Orr组及P袢组（P<0.05）。结论：远端空肠反口贮袋的Roux-en-Y吻合术是一种值得推荐的新型全胃切除术后消化道重建方法。     

肝移植围手术期出凝血功能障碍的防治

目的　探讨肝移植围手术期出凝血功能障碍的防治。方法　回顾性分析我院 2 0 0 2年 6月～ 2 0 0 3年 12月施行的 6 1例肝移植病例。结果　 6 1例肝移植术前肝功能ChildC级 35例 (5 7 4 % ) ,ChildB级 2 6例 (4 2 6 % ) ,ChildC组的患者术中凝血指标 (INR)的变化程度大于ChildB组 (P <0 0 5 )。与凝血有关的并发症中大出血 5例 (8 2 % ) ,肾衰 6例 (9 8% ) ,肝动脉血栓形成 5例 (8 2 % ) ,手术开展两阶段对比 ,第二阶段主要因限制了大量凝血药及血制品的使用 ,并发症明显减少。结论　掌握好不同时期、不同患者出血和血栓形成的平衡是防治肝移植围手术期出凝血功能障碍的关键
