Selective and nonselective shunts for variceal bleeding. A prospective study of 103 patients

Based on the experience reported herein, the following conclusions have been made: (1) Although nonoperative means, including sclerotherapy, have an important role in the management of bleeding varices, they are not definitive means of treating recurrent variceal hemorrhage. (2) Because of the maintenance of hepatopetal flow and splanchnic venous hypertension, a selective shunt is associated with a lower incidence of encephalopathy and provides a better quality of life than does a nonselective shunt. Thus, an elective distal splenorenal shunt is the elective operation of choice for recurrent variceal hemorrhage. (3) Nonselective shunts can be performed with similar expectation of patient survival as selective shunts, but because of increased encephalopathy, should be reserved for emergency operations, in cases of unsuitable venous anatomy, and in those patients with intractable ascites. (4) A well-conceived elective shunt procedure can be performed with low operative mortality and long-term patency, results in significant survival, and is still considered the "gold standard" for treatment of variceal bleeding.     

功能性鼻窦内窥镜手术100例疗效观察

目的：功能性鼻窦内窥镜手术的长期疗效。方法：采用Messerklinger术式为100例患者手术;并以传统术式治疗100例作对照。结果：内窥镜组临床治愈率81％,总有效率95％,明显优于传统手术组（P＜0．05）,手术并发症发生率为6％,明显低于传统组（P＜0．05）。结论：内窥镜手术长期疗效可靠,并发症少,复发率低。     

The association of Hospital Medicare beneficiary payer-mix,national quality rankings and outcomes following hepatopancreatic surgery

IntroductionWe sought to determine the impact of payer-mix on post-operative outcomes among Medicare beneficiaries following hepatopancreatic surgery.MethodsMedicare beneficiaries who underwent hepatopancreatic surgery were identified. Hospital quality markers were obtained from the Hospital General Information dataset. Hospitals were dichotomized (low/average vs. high) based on Medicare patient days versus all patient days irrespective of payer type.ResultsHigh Medicare patient-mix hospitals were more likely to be ranked higher than the national average relative to safety of care (29.4% vs. 38.1%) and timeliness of care (15.4% vs. 26.3%) versus low burden Medicare hospitals (both p < 0.001). However, Medicare beneficiaries who had hepatopancreatic surgery at a high Medicare patient-mix hospital were at higher risk of a complication (OR = 1.13, 95%CI 1.04–1.22), and death within 30-days (OR = 1.37, 95%CI 1.23–1.53) following surgery.ConclusionWhile hospitals caring for higher numbers of Medicare beneficiaries generally performed better on CMS quality indicators, these rankings did not equate to improved post-operative outcomes.
