Efficacy of transoral incisionless fundoplication (TIF) for the treatment of GERD: a systematic review with meta-analysis.

BACKGROUND: The efficacy of transoral incisionless fundoplication (TIF) performed with the EsophyX device (Redmond, Washington, USA) and its long-term outcomes in gastresophageal reflux disease (GERD) are debated. We, therefore, performed a systematic review with meta-analysis of studies evaluating the role of TIF in GERD. METHODS: A systematic search of EMBASE, SCOPUS, PubMed, and the Cochrane Library Central was performed. All original studies reporting outcomes in GERD patients who underwent TIF were identified. Only randomized controlled trials (RCTs) evaluating the efficacy of TIF, and prospective observational studies reporting outcomes after TIF were included. RESULTS: A total of 18 studies (963 patients) published between 2007 and 2015 were identified, including five RCTs and 13 prospective observational studies. The pooled relative risk of response rate to TIF versus PPIs/sham was 2.44 (95 % CI 1.25-4.79, p = 0.0009) in RCTs in the intention-to-treat analysis. The total number of refluxes was reduced after TIF compared with the PPIs/sham group. The esophageal acid exposure time and acid reflux episodes after TIF were not significantly improved. Proton-pump inhibitors (PPIs) usage increased with time and most of the patients resumed PPIs treatment at reduced dosage during the long-term follow-up. The total satisfaction rate after TIF was about 69.15 % in 6 months. The incidence of severe adverse events consisting of gastrointestinal perforation and bleeding was 2.4 %. CONCLUSIONS: TIF is an alternative intervention in controlling GERD-related symptoms with comparable short-term patient satisfaction. Long-term results showed decreased efficacy with time. Patients often resume PPIs at reduced doses in the near future.

Comparative effectiveness of warfarin in cirrhotic patients with non-symptomatic portal vein thrombosis: a multicenter, randomized controlled trial.

The effectiveness and risks of anticoagulant therapy in cirrhotic patients with non-symptomatic portal vein thrombosis (PVT) remain unclear. We conducted a multicenter, Zelen-designed randomized controlled trial to determine the effectiveness of warfarin in cirrhotic patients with non-symptomatic PVT during a one-year follow-up. In brief, 64 patients were 1:1 randomly divided into the anticoagulation group or the untreated group. The probability of recanalization was significantly higher in the anticoagulation group than those untreated in both ITT analysis (71.9% vs 34.4%, p = 0.004) and PP analysis (76.7% vs 32.4%, p < 0.001). Anticoagulation treatment was the independent predictor of recanalization (HR 2.776, 95%CI 1.307-5.893, p = 0.008). The risk of bleeding events and mortality were not significantly different. A significantly higher incidence of ascites aggravation was observed in the untreated group (3.3% vs 26.5%, p = 0.015). In conclusion, warfarin was proved to be an effective and safe as an anticoagulation therapy for treating non-symptomatic PVT in cirrhotic patients.

[Active Crohn's disease treated with acupuncture and moxibustion:a randomized controlled trial].

OBJECTIVE: To observe the effects and safety of clinical common symptoms of active Crohn's disease at the mild and moderate stages treated with acupuncture and moxibustion. METHODS: One hundred and two patients were randomly divided into an observation group and a control group, 51 cases in each one. Herb-partition moxibustion and acupuncture were used in the observation group. Herbal cakes with Huanglian (coptis chinensis), Fuzi (radix aconiti carmichaeli), Rougui (cinnamomum cassia), Muxiang (radices saussureae), Honghua (carthamus tinctorious), Danshen (the root of red-rooted salvia) and Danggui (angelica sinensis) as the main ingredients were used on Tianshu (ST 25), Qihai (CV 6) and Zhongwan (CV 12); acupuncture was used at Zusanli (ST 36), Shangjuxu (ST 37), Sanyinjiao (SP 6), Taixi (KI 3), Gongsun (SP 4) and Taichong (LR 3). Bran-partition moxibustion and shallow acupuncture were applied in the control group. Wheat bran-partition moxibustion in the shape of cake was implemented on the same acupoints as the observation group; shallow acupuncture was used 1~2 cm next to the acupoints. Treatment was given three times a week for 12 weeks, 36 times totally. Clinical effects of eight symptoms were evaluated by TCM symptom score, and the symptoms included abdominal pain (degree, frequency, time), diarrhoea (number, shape and frequency), fatigue, anorexia, borborygmus andflatus, fear of cold, soreness and weakness of waist and knees, tenesmus. RESULTS: After 12-week treatment, the eight symptoms were improved apparently (all P<0.05), with the scores of abdominal pain (degree, frequency, time), diarrhoea (shape and frequency), fatigue and anorexia in the observation group decreasing more obviously (all P<0.01). There was no statistical significance about the other symptom scores between the two groups (all P>0.05). CONCLUSIONS: Herb-partition moxibustion combined with acupuncture achieve safety and efficacy for mild and moderate Crohn's disease, and can improve the clinical common symptoms. Furthermore, their effects on abdominal pain (degree, frequency, time), diarrhoea (shape and frequency), fatigue and anorexia are better than those of bran-partition moxibustion and shallow acupuncture.
