Both the Swenson and the Soave procedures have been adapted as transanal approaches. Our purpose is to compare the outcomes and complications between transanal Swenson and Soave procedures.This clinical analysis involved a retrospective series of 148 pediatric patients with HD from Dec, 2001, to Dec, 2015. Perioperative/operative characteristics, postoperative complications, and outcomes between the 2 groups were analyzed. Students’ t-test and chi-squared analysis were performed.In total 148 patients (Soave 69, Swenson 79) were included in our study. Mean follow-up was 3.5 years. There are no significant differences in overall hospital stay and bowel function. We noted significant differences regarding mean operating time, blood loss, and overall complications. We noted significant differences in mean operating time, blood loss, and overall complications in favor of the Swenson group when compared to the Soave group (P < 0.05).According to our results, although transanal pullthrough Swenson cannot reduce overall hospital stay and improve bowel function compared with the Soave procedure, it results in less blood loss, shorter operation time, and a lower complication rate.

The third-generation semiconductor silicon carbide (SiC) has the characteristics of the wide band gap, high electric breakdown voltage, large saturated drift velocity, and high thermal conductivity, which are favorable for power devices under high-voltage, high temperature, and high-frequency scenarios [1,2] . Automotive applications are expected to remain a primary market for SiC power segments since they are one of the main drivers of the total power electronics market. The overall market for SiC devices is expected to exceed US$2.5 billion by 2025, with a compound annual
