Objective To evaluate the use of the kite flap (als o known as subcutaneous pedicled V-Y advancement flap)for the repair of moderate -sized anterior lamellar skin defects of eyelid. Methods Since 1994, kite flaps have been used to repair anterior lamellar skin defects of eyelids in 14 patients. Six patients were male and eight female, with a mean age of 43 years (range 15-64 years). The diameter of the largest defect reache d 1/3 length of the eyelid. The flaps were designed adjacent to the defects and the incision line corresponding to natural winkle lines on the eyelid. We underm ined the flap under the orbicular muscle, and advanced the flap to cover the def ect. The incisions were closed with 7-0 suture. Results After operation, all flaps survived with primary healing. Follow-up for 3 to 12 months showed that all cases had achieved satisfactory cosmetic effects without secondary deformity. Conclusions It is a simple, safe, an d reliable method to use kite flap for the repair of moderate-sized anterior la mellar eyelid skin defects that are too large to achieve primary approximation. Because kite-flap covers the defect through a direct advancement way without ro tation and twist, there are no dog-ear deformitys present at the pedical area a nd the repaired area looks smoothly. Because of its widely based muscle pedicle which incorporates venous and lymphatic drainage over most of its length, the un desirable pigment deposition is avoided.

Objective:To investigate the prognosis of cT3 and the subgroups of low rectal cancer patients who underwent neoadju-vant chemoradiotherapy (CRT) and evaluate whether all patients with cT3 low rectal cancer should undergo CRT. Methods:A total of 223 patients with cT3 low rectal cancer treated in the Department of Colorectal Surgery of Fujian Medical University Union Hospital from January 2008 to December 2012 were divided into neoadjuvant chemoradiotherapy group (CRT group) (115 cases) and no neoad-juvant chemoradiotherapy group (nCRT group) (108 cases) according to whether the patients underwent CRT. Afterward, the patients were retrospectively divided into three subgroups (mrT3a, mrT3b, and mrT3c) according to the proposed criteria of the Radiologic Soci-ety of North America (RSNA) by measuring the depth of mesorectal invasion (DMI) (DMI<5, DMI=5-10, and DMI>10 mm). The prog-noses of the two groups and their subgroups were compared. Results:The CRT and nCRT groups revealed no significant differences in the 3-year disease-free survival rate and the local recurrence rate for all the mrT3 patients (78.2%vs. 71.9%, P=0.608;4.4%vs. 8.5%, P=0.120) and mrT3a patients (82.4%vs. 81.8%, P=0.837;5.8%vs. 5.9%, P=0.658). On the contrary, for the mrT3b patients, the CRT and nCRT groups revealed significant differences in the 3-year disease-free survival rate (84.4%vs. 42.4%, P=0.032) and local recurrence rate (0.0%vs. 18.2%, P=0.014). For the mrT3b,c patients, the CRT and nCRT groups revealed no significant difference in the 3-year dis-ease-free survival rate (72.8%vs. 42.4%, P=0.060) but revealed a significant difference in the local recurrence rate (2.4%vs. 18.2%, P=0.021). COX regression analysis was utilized for 3-year disease-free survival, DMI and circumferential resection margin (CRM) were significant in the univariate analysis. Additionally, the multivariate analysis indicated that CRM is an independent impact factor (OR=2.249, CI 1.067-4.742, P=0.033). Conclusion:CRT can improve the prognosis of patients with mrT3b,c low rectal cancer but may not significantly influence the prognosis of patients with mrT3a and CRM-negative low rectal cancer;surgical treatment can be performed in these patients without CRT.
