Nylon Suture Loop for Tagging Lymphatic Channels during Lymphaticovenular Anastomosis.

Background Lymphaticovenular anastomosis (LVA) requires special supermicrosurgery techniques designed for vessels less than 0.8 mm in size. While preparing the field for LVA, it is often difficult to handle the lymphatic vessel directly without injuring it or fracturing it entirely. Method We propose a novel technique, which is used in LVA for tagging of lymphatic vessels, with the use of a nylon 6-0 suture and micro-ligaclip. Results We have successfully performed 78 LVAs in 26 cases with this method. The average lymphatic vessel size was 0.3 mm (0.15-0.8 mm). Conclusion This novel technique to implement the use of a nylon suture with a micro-ligaclip to use as a vessel loop for lymphatics has not been previously described in the literature. It is a useful technique that we find beneficial to lymphatic identification through tagging of the lymphatic channels, contributing to greater success in each anastomosis.

Dynamic Reconstruction of Anal Sphincter with Camera Shutter Style Double-Opposing Gracilis Flaps.

Fournier's gangrene is a life-threatening infection which requires prompt recognition, early surgical debridement of unhealthy tissue, and initiation of broad-spectrum antibiotics. Relook debridement are usually performed until all the devitalized tissue has been removed. Involvement of the anal sphincter may result in significant morbidity such as permanent incontinence. Dynamic reconstruction of the anal sphincter has always been one of the holy grails in the field of pelvic reconstruction. We demonstrate a new method of camera shutter style double-opposing gracilis muscle flaps that allows dynamic sphincteric function without the need for electrostimulation. The bilateral gracilis muscles are inset in a fashion that allows orthograde contraction of the muscle to narrow and collapse the neoanal opening. With biofeedback training, the patient is able to regain dynamic continence and return to function without a stoma. There was also no need for neurotization or microsurgery techniques to restore sphincteric function to the anus. The patient was able to reverse his stoma 14 months after the initial insult and reconstruction with biofeedback training without the use of electrostimulation.

Use of the extended pectoralis major myocutaneous flap as a wrap-around for mediastinal tracheal repair.

Persistent tracheoesophageal fistulas requiring flap repair of the trachea in the mediastinum are uncommon. A 44-year-old man developed a 5 cm x 2 cm persistent posterior tracheal defect after failed tracheo-esophageal fistula repair. The defect was patch repaired using the de-epithelialized skin paddle of an extended pectoralis major flap tunneled into the mediastinum. The use of cross-field ventilation, second rib removal and an anterior tracheostomy slit were crucial for posterior tracheal repair. No major complication occurred. The patch repair with the de-epithelialized skin paddle of pectoralis major flap mucosalized in 2 weeks and the patient was discharged one month postoperatively. The extended skin paddle of the pectoralis major flap was a useful method for tracheal wrap-around reconstruction.
