<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of pylorus-preserving pancreatico-duodenectomy(PPPD) in the treatment of periampullary adenocarcinoma by using Meta-analysis.</p><p><b>METHODS</b>From January 1, 1980 to November 8, 2013, the articles of randomized controlled trials (RCTs) about PPPD versus PD in the treatment of periampullary adenocarcinoma were collected from Cochrane Libriary, Embase, PubMed, Ovid, Web of science and CBM etc. The methodological quality of the included studies was evaluated according to Cochrane system review valuator handbook of risk of bias standards. Meta-analysis was performed by RevMan 5.2 software.</p><p><b>RESULTS</b>Seven RCTs were enrolled in the meta-analysis. Compared to PD group, PPPD group was associated with significantly less intraoperative blood loss (MD=-200.10, 95% CI:-400.66 to 0.46, P=0.05), shorter operation time (MD=-46.55, 95% CI:-91.02 to -2.07, P=0.04), and less postoperative blood transfusion (MD=-0.89, 95% CI:-1.59 to -0.19, P=0.01). There were no significant differences between the PPPD and PD group in pancreatic fistula, biliary fistula, intestinal fistula, abdominal abscess, postoperative bleeding, wound infection, relaparotomy, mortality and survival rate(all P>0.05).</p><p><b>CONCLUSIONS</b>PPPD in the treatment of the periampullary adenocarcinoma is safe and effective with similar survival of PD surgery. PPPD can reduce operative time, intraoperative blood loss, transfusion and does not increase the surgery complications as compared to PD.</p>

OBJECTIVE@#To compare the effectiveness of vocal cord cyst excision with electronic laryngoscope (EL) and self-retaining laryngoscope (SRM).@*METHOD@#Nightly-two patients, diagnosed as vocal cord cyst with strobolaryngoscope or electronic laryngoscope, were randomly divided into two groups. One group was 48 cases treated with electronic laryngoscope and another group was 44 cases treated with self-retaining laryngoscope. Electronic laryngoscopy examination and voice function assessments were performed to all patients, preoperatively and postoperatively at one week, three months and six months.@*RESULT@#One failed cases under SRM, difficult exposure of glottic portion, were treated under EL. The recurrence rate of the two groups was of no statistical significance in three months after operation. Voice function assessment of the two groups was of no statistical significance at one week, three months and six months after operation.@*CONCLUSION@#The operation under electronic laryngoscope is a minimal invasive procedure to the laryngeal mucosa. Electronic laryngoscope had advantages such as clear view, accurate operation. Furthermore, it can be used for those that could not be treated under self-retaining laryngoscope.
