The role of different imaging modalities: is MRI a conditio sine qua non for ETV?

Objective To describe the different imaging modalities used for the diagnosis and classification of hydrocephalus, their role in defining the optimal treatment of hydrocephalus and to define the optimal preoperative diagnostics for endoscopic third ventriculocisternostomy (ETV). Methods An overview on available imaging modalities for hydrocephalus will be given and their pros and cons discussed. In addition, different aspects of the treatment of hydrocephalus by shunts and by ETV will be highlighted. Discussion The role of the technical aspects of performing an ETV, the role of the surgeon’s philosophy, the role of the urgency of the procedure, and the role of informed consent on the requirements for the imaging of the hydrocephalus will be discussed. Conclusion The authors conclude that MRI is a conditio sine qua non for ETV in elective surgical cases.     

Symptoms, diagnosis and endoscopic management of common bile duct stones

Symptomatic BDS commonly cause significant morbidity and attempt at stone removal should be attempted if possible. Complications of CBDS include biliary colic, jaundice, cholangitis and pancreatitis. Investigations aimed to predict the presence of stones within the bile duct include serum bilirubin, AST, ALP, common bile duct diameter and age as independent predictors of choledocholithiasis. TUS is a sensitive test in detecting bile duct dilatation but the sensitivity is reduced in its ability to detect choledocholithiasis. A NIH consensus statement found that ERC, MRC and EUS were comparable in their sensitivities, specificities and accuracy rates for detection of choledocholithiasis. ERC and stone removal using a balloon or basket is often performed following EST. EBD may be performed if patients have uncorrected coagulopathies but the risk of pancreatitis is higher than for EST (although the risk of bleeding complications is lower for EBD). ML is often required in difficult to remove CBDS and using this device, CBDS can be removed in 90–95% of cases. Other forms of lithotripsy including laser lithotripsy and EHL are confined to specialised centres and the evidence for their use is based on small studies. ESWL may clear stones from the bile duct in up to 93% of patients but frequently ERC and stone fragment removal is required post ESWL. The role of medical therapy in difficult to remove CBDS (or in CBDS in patients with severe co-morbid illness preventing ERC + stone removal) is still currently uncertain due to a lack of large randomised control trials.     

Carcinoma of the papilla of vater: Are endoscopic appearance and endoscopic biopsy discordant?

Carcinoma of the papilla of Vater is classified as periampullary cancer representing 5% of all gastrointestinal tract malignancies. Early and accurate diagnosis is important for those patients with a tumor of the papilla, as the prognosis is more favorable than in other periampullary neoplasms. Endoscopically obtained biopsies from suspicious papillae can detect an early tumor, although even for skilled pathologists it is often difficult to differentiate carcinomas from noninvasive lesions on the basis of forceps biopsies. The purpose of this study was to assess the preoperative diagnostic accuracy of duodenoscopy appearance and biopsy in all cases with suspicion of tumor. Thirty patients with suspicion of carcinoma of the papilla of Vater and with final diagnosis established by pancreatoduodenectomy were included in this retrospective study. In each case, a comparison was made between endoscopic biopsy and duodenoscopic appearance. Duodenoscopic appearance sensitivity and accuracy for malignancy were 86% and 83%, respectively, whereas endoscopic biopsy sensitivity and accuracy were 65% and 67%, respectively. Although preoperative diagnosis of carcinoma of the papilla of Vater is useful for making therapeutic decisions, the diagnostic value of the endoscopic appearance was superior to endoscopic biopsy in this series.

胃肠道脂肪瘤的诊断与治疗

目的总结胃肠道脂肪瘤的诊断与治疗经验。方法回顾性分析1993年至2007年间收治的34例胃肠道脂肪瘤的临床资料。结果胃肠道脂肪瘤的临床表现无特异性,可并发肠套叠或肠梗阻,超声内镜的诊断准确率为93.8%。本组有12例行内镜下脂肪瘤切除术,22例行开腹手术（局部切除术及胃或肠部分切除吻合术）,手术过程顺利,未出现并发症。28例（82.4%）获1-168个月随访,1例胃底多发的脂肪肉瘤于术后2年死于肿瘤转移,其余27例均无复发或转移,存活至今。结论超声内镜是诊断胃肠道脂肪瘤的有效方法,手术是治疗胃肠道脂肪瘤的常规手段,内镜下切除胃肠道脂肪瘤可行。     

内镜黏膜下剥离术治疗直肠类癌

目的探讨内镜黏膜下剥离术（ESD）治疗直肠类癌的应用价值。方法肠镜发现直肠黏膜下肿块后进行微探头超声检查，对诊断为类癌者应用头端弯曲的针形切开刀进行内镜黏膜下剥离术治疗：（1）黏膜下注射生理盐水抬高病灶，使病灶与肌层分离；（2）预切开病灶周围黏膜；（3）剥离病变下方黏膜下层结缔组织，完整切除病灶。结果5例直肠类癌患者，肿瘤直径0.4～1.2（平均1．1）cm，均成功完成ESD治疗。ESD手术时间（自黏膜下注射至完整剥离病变）20-45（平均35）min；术中创面少量出血，均经电凝、氩离子血浆凝固和止血夹成功止血。不需再次肠镜下止血。1例剥离深至肌层，出现皮下气肿，保守治疗好转。术后全部经病理确诊。基底和切缘未见病变累及。1个月后肠镜复查，创面基本愈合。结论ESD是治疗直肠类癌的新方法．以往需要外科手术切除的肿瘤通过ESD可以达到同样的治疗效果。
