术前减轻黄疸对壶腹部癌行Whipple手术治疗效果的影响

目的:探讨术前减轻黄疸对壶腹部癌患者行Whipple手术治疗效果的影响。方法:回顾性分析2012年1月—2018年7月45例在Whipple手术术前行减轻黄疸治疗的壶腹部癌患者(减轻黄疸组)的临床资料,与同期34例行Whipple手术术前未行减轻黄疸治疗的壶腹部癌患者(未减轻黄疸组)的临床资料进行比较。比较两组患者术前、术中情况(手术时间、出血量、输血量)和术后并发症的差异。结果:减轻黄疸组患者治疗后总胆红素(TBil)、结合胆红素(DBil)、谷丙转氨酶(ALT)与治疗前比较差异有统计学意义(P<0.05)。两组R 0切除率比较差异无统计学意义(P>0.05)。减轻黄疸组手术时间、术中出血量、术中输血量优于未减轻黄疸组,差异均有统计学意义(P<0.05)。减轻黄疸组术后并发症发生率、胰漏发生率和胆漏发生率少于未减轻黄疸组,差异均有统计学意义(P<0.05)。结论:壶腹部癌患者行Whipple手术术前彻底减轻黄疸,可以缩短手术时间,减少术中出血量和术后并发症的发生。     

腹腔镜下经腹部和后矢状路联合修补术后复发性直肠尿道瘘和直肠阴道瘘

目的介绍腹腔镜下经腹部和后矢状路联合手术治疗直肠肛门手术后复发性直肠尿道瘘和直肠阴道瘘。方法5例术后多次复发性直肠尿道瘘或直肠阴道瘘患儿，男3例，女2例，年龄3～13岁。腹部在腹腔镜下游离结肠，远端尽可能从骶前向盆腔分离肠管，近端肠管游离保证正常结肠能无张力拖至肛门处吻合。低位盆腔肠管分离通过后矢状位切口（肛缘后上1cm），正中切开直肠后壁，直肠内剥离黏膜至齿状线，直视下修补瘘口，近端切断结肠，将正常结肠拖出与肛门吻合。结果所有患儿排便功能良好，仅1例有轻度污粪，未见瘘管复发。结论腹腔镜下经腹部和后矢状路游离结肠、直肠，创伤小，视野清晰，避开了粘连紧密的瘘管分离，完整结肠拖出避免了瘘管的复发，后矢状路直肠切开能直视下显示并修补瘘管。     

胰腺假性囊肿的诊治体会

目的 总结胰腺假性囊肿的诊治体会。方法 回顾性分析46例胰腺假性囊肿患者的临床资料，7例保守治疗，行内引流术12例，外引流术9例，序贯式内外引流术5例，胰腺部分切除术13例。结果 保守治疗者均痊愈，无复发；行内引流术者中有1例发生肠瘘，其余11例恢复良好无复发；行外引流术1例出现胰瘘，2例复发；行胰腺部分切除术者有1例出现胰瘘，其余恢复良好。结论 根据病情和病程选择合适的术式是治疗胰腺假性囊肿的关键。     

Does monthly native arteriovenous fistula blood-flow surveillance detect significant stenosis--a randomized controlled trial.

BACKGROUND: Clinical practice guidelines recommend that the preferred method of surveillance for arteriovenous fistula (AVF) is the measurement of AVF blood flow (Qa). As these recommendations are based on observational studies, we conducted a randomized, prospective, double-blind, controlled trial to assess whether Qa surveillance results in an increased detection of AVF stenosis. METHODS: A total of 137 patients were randomly assigned to receive either continuing AVF surveillance using current clinical criteria (control, usual treatment) or usual treatment plus AVF blood-flow surveillance by ultrasound dilution (Qa surveillance group). The primary outcome measure was the detection of a significant (>50%) AVF stenosis. RESULTS: There were 67 and 68 patients assigned to the control and Qa surveillance groups, respectively. Patients in the Qa surveillance group were twice as likely to have a stenosis detected compared with the control hazard ratio (HR) confidence interval (CI) group (2.27, 95% 0.85-5.98, P = 0.09), with a trend for a significant stenosis to be detected earlier in the Qa surveillance group (P = 0.09, log rank test). However, using the Qa results alone prior to angiography, the area under the receiver operating characteristic curve demonstrated, at best, a moderate prediction of (>50%) AVF stenosis (0.78, 95% CI 0.63-0.94, P = 0.006). CONCLUSION: This study demonstrates that the addition of AVF Qa monitoring to clinical screening for AVF stenosis resulted in a non-significant doubling in the detection of angiographically significant AVF stenosis. Further, large multi-centre randomized trials are feasible and will be necessary to confirm whether Qa surveillance and the correction of detected AVF stenosis will lead to a reduction in AVF thrombosis and increased AVF survival.     

Dural arteriovenous malformations at the base of the anterior cranial fossa: report of nine cases

Nine men with dural arteriovenous malformations (DAVM) at the base of the anterior cranial fossa are described. Four patients had intracerebral haemorrhage and four had seizures, associated with haemorrhage in two. In three cases the fistula was an incidental finding. In five cases the diagnosis could be made before angiography, on the basis of CT findings. Angiographically, venous drainage was always seen into ascending cortical veins. Five cases demonstrated drainage via the olfactory vein into the basal vein of Rosenthal; in four this way was the principal route of drainage. Five patients underwent surgery, the therapy of choice. One fistula closed spontaneously after angiography. Two patients refused treatment and one was not treated because of his poor general condition. Because arterial supply was usually bilateral, from small branches of the ophthalmic artery, embolisation seemed to be more dangerous. Compared to dural fistulae in other locations the DAVM of the anterior cranial fossa have a higher risk of complications and should be treated even if asymptomatic at the time of diagnosis.     

肠瘘患者腔静脉导管感染的回顾性分析

目的了解肠瘘患者腔静脉导管感染的发生率、细菌菌谱及药敏情况。方法对1998年1月至2001年4月收治的使用腔静脉导管进行全肠外营养(TPN)的肠瘘患者进行回顾性分析。结果216例肠瘘患者,共进行了358次腔静脉置管,腔静脉导管尖端培养阳性的有88次(24.6%),腔静脉导管平均使用时间为(16.9±13.0)d。88次腔静脉导管感染的尖端共培养出95株细菌,其中革兰阴性菌54株,占56.8%;其次为革兰阳性菌35株,占36.8%;真菌6株,占6.4%。根据药物敏感试验结果及临床表现,有16例患者更换了抗生素,4例改用抗真菌药物,所有患者均治愈。结论对于肠瘘患者,腔静脉感染仍是实施静脉营养的主要并发症之一,革兰阴性细菌感染最常见。

Ventricular septal fistula formation due to infectious endocarditis in a hemodialysis patient with aortic valve replacement

We report a case of infectious endocarditis in a 77-year-old woman who was undergoing maintenance hemodialysis therapy, and who was also having a prosthetic aortic valve replacement. The disease resulted from a local skin infection at the needle puncture site of the arteriovenous fistula. Ampicillin-resistant Staphylococcus aureus was the causal organism. Surgical treatment could not be performed because of associated intracranial hemorrhage due to septic embolism. In spite of intensive treatment with several antibiotics, a ventricular septal abscess just beneath the prosthetic aortic valve progressed to form a ventricular septal fistula. The resultant intracardiac left-to-right shunt led to refractory congestive heart failure. The patient finally died of heart failure. The formation of a ventricular septal fistula is considered to be a rare and extraordinary complication of infectious endocarditis in a hemodialysis patient with aortic valve replacement.

An Unusual Complication of Vesical Stones

The author reports a complicated recurrence of genital tract fistula. The initial vesicovaginal fistula resulted from obstructed labor, which was subsequently surgically managed without success. The patient had a recurrent vesicovaginal fistula that was formed by the erosion of vesical stones through the anterior endopelvic fascia into the vagina. The stones eventually eroded into the rectum, resulting in the formation of a complex vesicovaginal and rectovaginal fistula.
