Pelvic reconstruction following abdominoperineal resection or pelvic exenteration is associated with signification surgical site morbidity. Immediate pelvic reconstruction with a muscle flap is now the gold standard, associated with reduced perineal morbidity compared to primary closure alone.2,3 The purpose of the present study was to directly com...

Reconstruction of the nipple–areolar complex usually marks the final stage of breast reconstruction in postmastectomy patients. There are many approaches to the nipple reconstruction using autologous, allogenic, and synthetic materials. However, different methods have their own pros and cons and there is no current consensus for the best technique....
Article
Neuronavigation, a ubiquitous tool used in neurosurgery, is rarely used in maxillofacial reconstructive surgery despite it offering many advantages without any disadvantage to the patient. The present report describes one patient with complex gun-shot wound facial injury and one patient with a rare malignant peripheral nerve sheath tumor involving...
Article
To review the clinical outcomes of treatment for adult wrist ganglions and to conduct a meta-analysis comparing the 2 most common options: open surgical excision and aspiration. The review methodology was registered with PROSPERO. We performed a systematic search of MEDLINE and EMBASE for articles published between 1990 and 2013. Included studies r...
Article
Background There is a strong body of evidence addressing short-term outcomes following wrist ganglion aspiration; however, few studies have investigated long-term outcomes and patient satisfaction. Objective To evaluate patient satisfaction and the long-term rate of recurrence following wrist ganglion aspiration. Methods Charts of all patients wi...

INTRODUCTION: There are many treatments for wrist ganglia. The objective of this study was to review the clinical outcomes of all ganglia treatment modalities and to generate a meta-analysis comparing the two most common options: open surgical excision and aspiration. MATERIALS & METHODS: Review methodology was registered with PROSPERO. A systemat...

Article
Background: The purpose of this study was to prospectively assess clinical outcomes in patients undergoing a new method of donor site management for radial forearm free flaps. Methods: 177 patients underwent reconstruction of ablative defects of the head and neck using a radial forearm free-flap. All patients had topical tissue expansion tapes a...
Article
The use of the DynaClose topical tissue expansion device for closure of radial forearm free flap (RFFF) donor sites has been demonstrated to significantly reduce healing time and postoperative pain compared to the traditional use of a split-thickness skin graft. However, long-term cosmetic and functional outcomes are not known. The objective of thi...
Article
The objective of this study is to test the hypothesis that using a non-invasive and inexpensive pre-operative tissue expansion device (DynaClose) for radial forearm free-flap donor sites will result in a significant reduction in the cost of both in-hospital and out-of-hospital wound care compared with that of unexpanded radial forearm free-flap don...
Article
Full-text available
Over 70% of Canadian carpal tunnel syndrome (CTS) operations are performed outside of the main operating room (OR) with field sterility and surgeon-administered pure local anesthesia [LeBlanc et al., Hand 2(4):173-8, 14]. Is main OR sterility necessary to avoid infection for this operation? This study evaluates the infection rate in carpal tunnel r...
Article
The objective of this study is to test the hypothesis that using a simple and inexpensive preoperative tissue expansion device for radial forearm free flap donor sites will result in a significant reduction in healing time and reduced postoperative pain compared to unexpanded radial forearm free flap donor site skin. Twenty-nine patients were enrol...
Conference Paper
Purpose: More than 70% of Canadian carpal tunnel operations are now performed outside of the main operating room with field sterility (1). Main OR sterility comes with a fourfold cost in money, and generates considerably more garbage (see figure 1). Is main OR sterility really necessary to avoid infection? This study evaluates the infection rate in...
Article
The objective of this study was to significantly reduce the donor site morbidity associated with use of the radial forearm free flap (RFFF). A pilot study to test the feasibility of topical tissue expanders to close the RFFF donor site. The setting was a tertiary care teaching hospital. This pilot study consisted of a series of 21 cases that used t...

In damage-control surgery, definitive abdominal closure may not be possible for several days or weeks after laparotomy until the patient has stabilized. We present 23 patients treated with the Canica ABRA dynamic wound closure system that re-approximated open abdomens with silicone elastomers placed transfascially across the wound. This study aimed...

Obesity is a major risk factor for type 2 diabetes and cardiovascular disease. However, current strategies to achieve sustained weight loss are often unsuccessful. Fat reaccumulation might be favored by enhanced adipose cell differentiation or survival in the postreduced state. We measured adipogenic and apoptotic protein expression in subcutaneous...
Article
We present a case of difficult esophageal reconstruction after total esophagectomy for iatrogenic perforation in a diseased esophagus. The stomach was used for esophageal reconstruction as a retrosternal microvascularly augmented flap; the vascular supply to the stomach had been interrupted during previous abdominal operations. The blood supply to...
Article
The radial forearm osteocutaneous free flap has become a standard method of mandible reconstruction. In order to improve the contour of the reconstructed jaw in large resections, especially the anterior defect, the radial forearm bone graft needs to be osteotomized. The bone graft is nourished by small branches of the radial artery via the fascial...
Article
A modified technique to assess integrity of the rat blood--brain barrier is described in which a poorly permeating radiotracer is injected intravenously and its net permeation across the cerebral vasculature in 30 min is related to its time-averaged level in the circulation. At the termination of experiments, direct carotid arterial perfusion clear...
