Single incision laparoscopic right hemicolectomy: different approaches / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Single incision laparoscopic colectomy has been performed in recent years, and has been shown to be feasible and safe. This study was to assess the feasibility of single incision laparoscopic right hemicolectomy and to compare the differences in different approaches.</p><p><b>METHODS</b>This retrospective study included eighteen patients with carcinoma of caecum and ascending colon, undergoing single incision laparoscopic right hemicolectomy. This study also compared single incision laparoscopic right hemicolectomy using different approaches: (1) single incision multiport, (2) single access port and (3) glove port.</p><p><b>RESULTS</b>There was no statistical difference in surgical outcomes. Concerning the surgeon's satisfaction toward three methods, overcrowding and durability were similar but the single incision multiport was associated with the highest gas-leak and the "glove" port was associated with poor durability. However, the method of single incision multiport has the lowest average cost of the special trocar or port in each operation. The operative time and blood loss of the operations in this study were comparable to previous publications.</p><p><b>CONCLUSION</b>There was no significant difference between different approaches of single incision laparoscopic right hemicolectomy for colonic cancer in right side colon.</p>

Efficacy and safety of on demand tadalafil in the treatment of East and Southeast Asian men with erectile dysfunction: a randomized double-blind, parallel, placebo-controlled clinical study / 亚洲男科学杂志(英文版)

<p><b>AIM</b>To assess the efficacy and safety of tadalafil in comparison to a placebo, when taken on demand for 12 weeks by East/Southeast Asian men with erectile dysfunction (ED).</p><p><b>METHODS</b>This multicenter, randomized, double-blind, parallel group, placebo-controlled study was conducted at 17 centers across East and Southeast Asia between August 2002 and February 2003. Men more than 18 years of age with mild to severe ED of various etiologies were randomized to receive a placebo or 20 mg of tadalafil taken as needed (maximum once daily). Efficacy assessments included the International Index of Erectile Function, the Sexual Encounter Profile diary and Global Assessment Questions.</p><p><b>RESULTS</b>Tadalafil significantly improved erectile function as compared to the placebo (P < 0.001). At the endpoint, the patients receiving 20 mg of tadalafil reported a greater mean per patient percentage of successful intercourse attempts (Sexual Encounter Profile question 3: 70.9% compared to 33.5% in the placebo) and a greater proportion of improved erections (Global Assessment Question: 86.2% compared to 30.1%). Most (= or < 3%) treatment emergent adverse events were mild or moderate. The most common treatment emergent adverse events were headache, back pain, dizziness and dyspepsia.</p><p><b>CONCLUSION</b>Tadalafil was an effective and well-tolerated treatment for ED in East and Southeast Asian men.</p>
