ObjectiveTo analyze the surgical procedures and clinical effects of surgical treatment for patients with hypertrophic obstructive cardiomyopathy (HOCM). MethodsWe retrospectively analyzed the clinical data of sixty-five consecutive patients with HOCM who underwent modified Morrow procedure in Wuhan Asia Heart Hospital between June 2010 and December 2013. There were 40 males and 25 females with mean age of 48.4±11.5 years (ranged 18-70 years). ResultsThere was no in-hospital mortality. There was no valve injury or ventricular septal perforation occurred during operation. Postoperative LVOT gradient, interventricular septum (IVS), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) and mitral regurgitation (MR) were significantly lower than preoperative values (P<0.05). Complete atrioventricular block occurred in 3 patients, complete left bundle branch block occurred in 7 patients, and left anterior division block occurred in 3 patients. All patients were followed up for 6-35 months. During the following-up time, the clinical symptoms diminished in 55 patients and ameliorated significantly in other 10 patients. All patients had a NewYork Heart Association functional class Ⅰ/Ⅱ during the follow-up. ConclusionSurgical septal myectomy can eliminate obstruction of left ventricular outflow tract and relief symptoms obviously. The early and mid-term outcomes are satisfactory.
ObjectiveTo systematically review the effects of enteral feeding pump and intermittent bolus nasogastric feeding on gastric retention, diarrhea, regurgitation, and other complications of patients who received enteral nutrition treatment. MethodsWe electronically searched databases including PubMed (1980-2013.9), Wiley Online Library (1990-2013.9), Elsevier (1990-2013.9), CNKI (1990-2013.9), VIP (1989-2013.9) and WanFang Data (1990-2013.9), to collect randomized controlled trials (RCTs) about enteral feeding pump and intermittent bolus nasogastric feeding. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality of the included studies, and then meta-analysis was performed using RevMan 5.2.6 software. ResultsA total of 16 trials involving 1 263 patients were finally included. The results of meta-analysis indicated that enteral feeding pump was better than intermittent bolus nasogastric feeding in the incidences of gastric retention (OR=0.27, 95%CI 0.16 to 0.45, P < 0.000 01), diarrhea (OR=0.24, 95%CI 0.16 to 0.34, P < 0.000 01), regurgitation (OR=0.26, 95%CI 0.11 to 0.65, P=0.004), aspiration (OR=0.19, 95%CI 0.11 to 0.32, P < 0.000 01), aspiration pneumonia (OR=0.40, 95%CI 0.23 to 0.68, P=0.000 7), and abdominal distension (OR=0.24, 95%CI 0.10 to 0.57, P=0.001), with significant differences. However, they were alike in the incidence of tub obstruction (OR=0.43, 95%CI 0.14 to 1.29, P=0.13). ConclusionAccording to existing relevant RCTs, enteral feeding pump is better than intermittent bolus nasogastric feeding in reducing enteral nutrition complications to some extent. However, due to the low methodological quality of the included studies, more large-scale, multicentre high quality RCTs are still needed to verify the aforementioned conclusion.
