Objectives: A lazy S-shaped postauricular incision with a modified double-flap technique has been used for cochlear implant surgery at our institution for the past 10 years. The postoperative surgical complications, morbidity, and outcome of this technique were evaluated.
Methods: A retrospective case review was conducted in a tertiary referral teaching center. A total of 342 patients with profound sensory hearing loss (173 female and 169 male subjects; age range, 11 months to 52 years) who underwent cochlear implantation using the double-flap postauricular transmastoid surgical approach during a 5-year period (2005 through 2009) with at least 5 years' follow-up were retrospectively evaluated. Postoperative wound complications were identified. Major complications included flap necrosis, wound infection requiring surgical intervention, and wound dehiscence with or without implant exposure. Swelling over the implant and superficial wound infections treated medically were considered minor complications. Other non-wound-related complications, surgical time, and number of electrodes inserted were also recorded.
Results: The surgical approach was accomplished in all the patients with four minor wound complications. The mean surgical time was 1.4 hours, and the mean time between surgery and the programming process was 2 weeks.
Conclusion: This modified double-flap technique was easy to perform and appeared to reduce the incidence of wound complications in cochlear implant surgery. It allowed programming of the implant after a shorter period of time.

Purpose: The double-flap technique (DFT) is an anti-reflux reconstruction procedure performed after proximal gastrectomy (PG), but its complexity and high incidence of anastomotic stenosis are problematic. We conducted this study to demonstrate the efficacy of robot-assisted DFT, with refinements, to address these issues.
Methods: Surgical outcomes were compared between the following procedures modified over time at our institution: conventional open DFT (group O, n = 16); early robotic DFT (group RE, n = 19), which follows the conventional open PG approach; and late robotic DFT (group RL, n = 21), which incorporates refinements to the early robotic DFT technique by exploiting more of the robotic capabilities available.

Objective: It is challenging to reconstruct defects resulting from surgical procedures in areas with high tension. We present modified kite flaps that allowed us to reconstruct the defect with high mechanical tension.
Methods: With the combination of advancement and rotation, the defect using bilateral modified kite flaps closes with significantly reduced tension.

Technique: Although the double flap technique effectively reduces the incidence of postoperative reflux esophagitis and anastomotic leakage after laparoscopic gastrectomy, its clinical application is restricted because the procedure is technical complex. We devised a modified esophagogastric reconstructive method which we termed the "arch-bridge-type" reconstruction. This reconstruction method was performed for a 71-year-old man, who was admitted to our hospital with the diagnosis of cT2N0 upper gastric cancer.

A colorimetric and photothermal dual readout biosensor for Flap endonuclease 1 (FEN1) quantification was developed on the basis of target-prevented gold nanoparticles (AuNPs) aggregation. The exposed 5'-flap of double-flap DNA substrate modified on SAMBs was firstly cleaved by FEN1. Large amount of cleaved 5'-flap remained in the supernatant after simple magnetic separation, which can adsorb on the surface of AuNPs and effectively prevent the dispersed AuNPs from aggregation under high ionic concentration, accompanied with the color changing of the system, which can be recognized by nake eyes easily.

Background: Due to its nutritional advantages over total gastrectomy, proximal gastrectomy (PG) with anti-reflux techniques has gained significant attention in East Asian countries in recent years. The double flap technique (DFT) and modified side overlap and fundoplication by Yamashita (mSOFY) are two promising anti-reflux interventions following PG. However, anastomotic stenosis after DFT and gastroesophageal reflux after mSOFY have been reported in several patients.
