Hepatorenal syndrome (HRS), a serious complication of cirrhosis, is associated with high mortality without treatment. Terlipressin with albumin is effective in the reversal of HRS. Where terlipressin is not available, as in the United States, midodrine and octreotide with albumin are used as an alternative treatment of HRS. The aim was to compare the effectiveness of terlipressin plus albumin versus midodrine and octreotide plus albumin in the treatment of HRS in a randomized controlled trial. Twenty‐seven patients were randomized to receive terlipressin with albumin (TERLI group) and 22 to receive midodrine and octreotide plus albumin (MID/OCT group). The TERLI group received terlipressin by intravenous infusion, initially 3 mg/24 hours, progressively increased to 12 mg/24 hours if there was no response. The MID/OCT group received midodrine orally at an initial dose of 7.5 mg thrice daily, with the dose increased to a maximum of 12.5 mg thrice daily, together with octreotide subcutaneously: initial dose 100 μg thrice daily and up to 200 μg thrice daily. Both groups received albumin intravenously 1 g/kg of body weight on day 1 and 20‐40 g/day thereafter. There was a significantly higher rate of recovery of renal function in the TERLI group (19/27, 70.4%) compared to the MID/OCT group (6/21, 28.6%), P = 0.01. Improvement in renal function and lower baseline Model for End‐Stage Liver Disease score were associated with better survival. Conclusion: Terlipressin plus albumin is significantly more effective than midodrine and octreotide plus albumin in improving renal function in patients with HRS (Hepatology 2015;62:567–574

Background: Cold polypectomy techniques (without electrocautery) by means of biopsy forceps or snare are widely adopted for the removal of subcentimetric polyps. However, few data are available on the safety of this approach. The aim of this study was to assess the safety of cold polypectomy for subcentimetric polyps, as well as the rate of advanced neoplasia in these lesions. Patients and methods: In a prospective multicenter trial, consecutive patients with at least one < 10-mm polyp at colonoscopy were prospectively included. All of the < 10-mm polyps detected within the study period were removed by cold polypectomy. The rates of immediate or delayed bleeding and other complications were assessed at 7 and 30 days after cold polypectomy by telephone calls. The rate of advanced histology was also assessed. Predictive variables of postpolypectomy bleeding or advanced neoplasia were identified by multivariate analysis. Results: A total of 1015 < 10-mm polyps in 823 patients (15.5 % on antiplatelet agents) were removed. Of these, 822 (81 %) were ≤ 5 mm and 193 (19 %) were 6 – 9 mm. Immediate postpolypectomy bleeding occurred in 18 patients, corresponding to a per-patient and per-polyp bleeding rate of 2.2 % (95 % confidence interval [CI] 1.2 % – 3.2 %) and 1.8 % (95 %CI 1 % – 2.6 %), respectively. Therapy with antiplatelet agents (odds ratio [OR] 4; 95 %CI 1.5 – 10.6) and larger polyp size (OR 2; 95 %CI 1.1 – 6.9) were independent predictors of bleeding. Bleeding was successfully treated by endoscopic hemostasis in all cases and required no further medical intervention. Advanced neoplasia prevalence in polyps ≤ 5 mm was as high as 8.7 %. Conclusions: The results from this study showed the high safety of a cold polypectomy approach for subcentimetric polyps. This was due to the low rate of postpolypectomy bleeding and to the high efficacy of endoscopic hemostasis in its treatment. The high rate of advanced neoplasia in polyps ≤ 5 mm should prompt some caution on the management of these lesions following detection at computed tomography colonography or colon capsule endoscopy.

: Large spontaneous portal-systemic shunts have been occasionally described in patients with cirrhosis. This study was undertaken to assess the prevalence of portal-systemic shunts in patients with cirrhosis with recurrent or persistent hepatic encephalopathy (HE) as compared with patients with cirrhosis without HE. Fourteen patients with cirrhosis with recurrent or persistent HE (cases) and 14 patients with cirrhosis without previous or present signs of overt HE matching for age and degree of liver failure (controls) were studied. Each patient underwent neurological assessment and cerebral magnetic resonance (MR) imaging to exclude organic neurological pathological conditions. HE evaluation included psychometric performance (Trail-Making Test A), electroencephalogram (EEG), mental status examination and grading, arterial, venous, and partial pressure of ammonia determination. The presence of portal-systemic shunts was assessed by portal venous phase multidetector-row spiral computed tomography (CT). Large spontaneous portal-systemic shunts were detected in 10 patients with HE and in only 2 patients without HE (71% vs. 14%; chi square = 9.16; df = 1.0; P = .002). The patients with HE presented ascites ( P = .002) and medium/large esophageal varices ( P = .02) less frequently than the control group. In conclusion , our study suggests that large spontaneous shunts may often sustain the chronicity of HE; the presence of large shunts should be sought in patients with cirrhosis with recurrent or persistent HE.
