The success of a repair is assessed by two essential criteria: The functional character of the lip (restoration of continence allowing feeding) and the aesthetic quality of the repair. However, for many patients from countries whose medical infrastructure does not allow them to undertake complex reconstructions locally, medical transfers represent their only chance of treatment. The aim of this article is to share with you an extreme clinical case of labial reconstruction, the management of which was a real challenge, using two major flaps: the free ante-brachial flap and the DUFOURMENTEL-type bi-pediculated scalp flap.展开更多

Many surgical models emphasize learning the technical and manual dexterity skills necessary to be a surgeon, yet few focus on obtaining the theoretical and abstract skills needed for planning complex cutaneous surgical repairs with flaps and grafts. We developed and evaluated a novel surgical flaps and grafts workshop for residents through the Department of Dermatology. Methods: Participants received a 60 minute PowerPoint lecture focusing on the basic principles of cutaneous repair with flaps and grafts, with examples and explanation of each of the four main types of flaps and grafts. The participants then received nine photocopies of Mohs micrographic surgery defects with instructions to design three repairs, focusing on functional and aesthetic outcome. Hypothetical and actual repair designs were then discussed in an open forum format. Anonymous surveys administered to 11 dermatology residents assessed their knowledge level, confidence level, and likelihood of using flaps and grafts pre- and post-workshop using Likert scales. Overall experience was also assessed. A paired sample Wilcoxon Signed Rank Test was used for analysis, since the data was non-parametrically distributed. Results: There was a statistically significant increase in confidence performing flaps post workshop (p = 0.0469). There was also an increase in knowledge of flaps and grafts, confidence in planning flaps and grafts, and confidence in performing grafts post workshop, but these findings did not reach statistical significance. The workshop had no effect on expected future use of flaps and grafts. Conclusions: The surgical workshop is a novel simulation teaching tool for learning basic principles and design of flaps and grafts in cutaneous surgery.展开更多

Anal stenosis represents a technical challenge in terms of surgical management. A Medline search of studies relevant to the management of anal stenosis was undertaken. The etiology, pathophysiology and classification of anal stenosis were reviewed. An overview of surgical and non-surgical therapeutic options was developed. Ninety percent of anal stenosis is caused by overzealous hemorrhoidectomy. Treatment, both medical and surgical, should be modulated based on stenosis severity. Mild stenosis can be managed conservatively with stool softeners or fiber supplements. Sphincterotomy may be quite adequate for a patient with a mild degree of narrowing. For more severe stenosis, a formal anoplasty should be performed to treat the loss of anal canal tissue. Anal stenosis may be anatomic or functional. Anal stricture is most often a preventable complication. Many techniques have been used for the treatment of anal stenosis with variable healing rates. It is extremely difficult to interpret the results of the various anoplastic procedures described in the literature as prospective trials have not been performed. However, almost any approach will at least improve patient symptoms.展开更多
