ABSTRACT

Objective:To evaluate the long-term results of bipolar radiofrequency(BRF) ablation in restoring sinus rhythm in patients with permanent atrial fibrillation(AF) undergoing surgery for cardiac surgery.Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent cardiac operations concomitant BRF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events.Results:15 patients died in the early postoperative period, perioperative mortality rate was 5.5%. The rate of stable sinus rhythm(sSR)was 86.6%, 75.4%, 67.7%, 57.8% in 1, 2, 5, 8 years after operation. Multivariate analysis proved the size of the left atrium( HR=1.073, P<0.001) and duration of AF( HR=1.070, P=0.025) to be an independent predictor of the radiofrequency ablation outcome. Conclusion:Bipolar radiofrequency maze procedure can effectively eliminate AF, maintain long-term of sinus rhythm. Bipolar radiofrequency maze procedure is a safe, easy and effective surgical option for the treatment of AF, with satisfactory long-term results, is worthy of promotion.

ABSTRACT

Objective:To evaluate the long-term results of combined ganglion plexus ablation(GPA) during radiofrequency ablation(RF) with long-standing persistent atrial fibrillation(LSP-AF).Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent valve operations concomitant RF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events. Propensity score matching conducted by RF and RF+ GPA resulted in 102 patients per group.Results:Independent predictors for rhythm success at 1 year were combined GPA( OR=0.205, P=0.005), smaller left atrium size( OR=1.091, P=0.000); at 5-year and 8-year were a shorter history of AF( OR=1.069, P=0.023; OR=1.066, P=0.030), and smaller left atrium size( OR=1.091, P=0.000; OR=1.086, P=0.000). After matching, RF+ GPA group had significantly higher sinus rhythm(SR) without antiarrhythmic drugs(AADs) at 6 months(91.3% vs. 79.8%, P=0.026), 1-year(90.2% vs. 78.5%, P=0.028), but there were no difference between the two groups at 5-year(64.8% vs. 64.4%, P=0.956), and 8-year(53.3% vs. 50.6%, P=0.711). During the 6 postoperative months, fewer patients in the RF+ GPA group underwent follow-up cardioversions(2.0% vs. 8.8%, P=0.030). Actuarial survival curves did not differ significantly between the 2 groups( HR=1.327, 95% CI 0.4633-3.802, P=0.598). Conclusion:The combination of GPA can be effective at the early postoperative stage for SR restoration in Maze Ⅳ procedures for the treatment of LSP-AF in heart valve surgeries, particularly for lower AADs use and lower cardioversions. However, this effect will gradually diminish after one year.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the application of three-stitch preventive transverse colostomy in anterior resection of low rectal cancer.</p><p><b>METHOD</b>From May 2015 to March 2016, 70 consecutive low rectal cancer patients undergoing anterior resection and preventive transverse colostomy in our department were recruited in this prospective study. According to the random number table method, 70 patients were divided into three-stitch transverse colostomy group(observation group, n=35) and traditional transverse colostomy group(control group, n=35). Procedure of three-stitch preventive transverse colostomy was as follows: firstly, at the upper 1/3 incision 0.5-1.0 cm distance from the skin, 7# silk was used to suture from outside to inside, then the needle belt line went through the transverse edge of the mesangial avascular zone. At the lower 1/3 incision 0.5-1.0 cm distance from the skin, 7# silk was used to suture from inside to outside, then silk went through the transverse edge of the mesangial avascular zone again and was ligatured. Finally, in the upper and lower ends of the stoma, 7# silk was used to suture and fix transverse seromuscular layer and the skin. The operation time and morbidity of postoperative complications associated with colostomy were compared between two groups.</p><p><b>RESULTS</b>There were no significant differences in baseline data between the two groups(all P>0.05). The operative time of observation group was shorter than that of control group [(3.2±1.3) min vs. (15.5±3.4) min, P<0.05]. Incidences of colostomy skin-mucous separation, dermatitis, stoma rebound were significantly lower in observation group [5.7%(2/35) vs. 34.3%(12/35), P=0.007; 8.6%(3/35) vs. 31.4%(11/35), P=0.036; 0 vs. 17.1%(6/35), P=0.025, respectively], while incidences of parastomal hernia and stoma prolapse in two groups were similar (both P>0.05).</p><p><b>CONCLUSION</b>Compared with traditional transverse colostomy method, the three-stitch preventive transverse colostomy has more operating advantages and can reduce postoperative complications associated with colostomy.</p>
