¿Cúan segura es la dermatología quirúrgica?. Trabajo de investigación prospectivo sobre sus complicaciones realizado en una sala de procedimientos / How safe is dermatologic surgery? Prospective reserach work on complications in dermatologic surgery located in an office-based setting

Antecedentes: Aunque las complicaciones globales en la dermatología quirúrgica referidas en la bibliografía mundial son bajas (1,64- 4,58%), las publicaciones regionales con datos prospectivos sobre ellas son escasas y, a nivel nacional, inexistentes. Objetivos: Estimar la incidencia de complicaciones intraquirúrgicas (CI) y posquirúrgicas (CP) en los procedimientos de cirugía dermatológica y caracterizarlas en el ámbito de una sala de procedimientos de un hospital de referencia de la Ciudad Autónoma de Buenos Aires. Diseño: Trabajo de investigación descriptivo, prospectivo, observacional y longitudinal. Materiales y métodos: Se recolectó información demográfica del paciente y operativa en el momento del procedimiento quirúrgico. Se clasificaron las complicaciones quirúrgicas que se presentaron hasta un mes posterior al procedimiento en los pacientes intervenidos en la sección de Dermatología Quirúrgica del Hospital F. J. Muñiz, en el período comprendido entre febrero de 2015 y marzo de 2018. Resultados: Se halló una incidencia de 0% (IC 95%: 0 a 0,4) para las CI y de 4,4% (IC 95%: 3,2 a 5,9) para las CP en una serie de 765 pacientes (937 procedimientos). La CP más frecuente fue dehiscencia (68%), seguida de infección (16%), variantes de sangrado (9%) y necrosis (7%). Ninguna fue grave ni incluyó muerte, hospitalización o secuelas permanentes. Conclusiones: La dermatología quirúrgica en el ámbito de una sala de procedimientos es segura y el porcentaje de complicaciones es bajo comparable con lo publicado en la bibliografía internacional.

Background: Although the global complications in surgical dermatology referred to in the worldwide literature are low (1.64- 4.58%), regional publications with prospective data on them are scarce and nationally non-existent. Objectives: Estimate the incidence of intra-surgical complications (IC) and post-surgical complications (PC) in dermatological surgery procedures and characterize them within the scope of a reference hospital in the Autonomous City of Buenos Aires. Design: Descriptive, prospective, observational and longitudinal research work. Materials and methods: Demographic information of the patient and operative data were collected at the time of the surgical procedure. Surgical complications that occurred up to one month after the procedure on patients undergoing surgery in the surgical dermatology section of the F. J. Muñiz Hospital between February 2015 to March 2018 were classified. Results: The incidence found was 0% (95% CI 0-0.4) for IC and 4.4% (95% CI 3.2-5.9) for PC in a series of 765 patients (937 procedures). The most frequent PC was dehiscence (68%), followed by infection (16%), bleeding variants (9%) and necrosis (7%). Neither the PC were severe, not included death, hospitalization or permanent sequelae. Conclusions: Office based dermatologic surgery is safe and the percentage of complications is low, comparable to that published in the international literature. (AU)

Effect of short-term ischemia on microcirculation and wound healing of adipocutaneous flaps in the rat

Abstract Purpose Composite flaps used in reconstructive surgery may intra- and postoperatively suffer from hypoperfusion and/or ischemia-reperfusion influencing wound healing. We aimed to follow-up the effect of ischemia on adipocutaneous flaps' wound healing and microcirculation. Methods In anesthetized rats groin flaps were formed bilaterally. In Control group the flaps were repositioned and sutured back. In Ischemia-Reperfusion (I/R) group before repositioning and suturing the flap pedicles were clamped for 60 minutes. Laser Doppler (LD) fluxmetry and temperature probes were applied on the cranial, central and caudal flap regions before/after preparation and ischemia, re-suturing, and on the 1st-3rd-5th-7th-14th postoperative days, before the final examinations and biopsies for histology. Results Flaps' skin temperature quickly recovered after repositioning. LD values were lower in the I/R group, reaching a significant level by the 3rd postoperative day, and remained lowered till the 14th day. The magnitude of alterations differed in the flap regions. Histologically normal wound healing process was seen, except for some I/R flaps, where hypertrophized mammary glands were found. Conclusions Short-term ischemia could influence flap microcirculation and wound healing, and may result in hypertrophized mammary glands. Laser Doppler could be used to evaluate intra- and postoperative microcirculatory changes and may have significance in predicting complications.

Complicaciones y manejo de procedimientos dermatoestéticos: una actualización para el dermatólogo / Complications associated with cutaneous aesthetic procedures: an update for the dermatologist

En las últimas décadas se han desarrollado nuevas técnicas e indicaciones de los procedimientos estéticos mínimamente invasivos, presentando cada vez mejores resultados con un alto nivel de seguridad, sin embargo, estos no se encuentran exentos de complicaciones, las que pueden ser transitorias o permanentes. El conocimiento, abordaje, tratamiento y prevención de las distintas complicaciones son esenciales para los dermatólogos y cirujanos plásticos. Los procedimientos más utilizados son: administración de rellenos, peeling químicos, láser, luz pulsada intensa y ultrasonido de alta frecuencia. La siguiente revisión tiene como objetivo reconocer las principales complicaciones de estos procedimientos y su manejo.

In recent decades, new techniques and indications of minimally invasive aesthetic procedures have been developed, presenting increasingly better results with a high level of safety, however these are not exempt from complications, which may be transient or permanent. The knowledge, approach, treatment and prevention of the different complications are essential for the dermatologist and plastic surgeons. The most used procedures are the administration of fillers, chemical peels, lasers, intense pulsed light and high frequency ultrasound. The following review aims to recognize the main complications of these procedures and their management.

Técnicas para retirada de enxertos primários de retalhos traumáticos em áreas de desenluvamento / Techniques for removal of primary grafts from traumatic skin flaps in areas with degloving injuries

No tratamento dos pacientes vítimas de desenluvamento atendidos de maneira correta e precoce, a enxertia primária, com utilização da pele proveniente dos retalhos traumáticos é fundamental. Podem ser utilizados enxertos em ambas as espessuras, parcial ou total, não existindo na literatura uma definição em relação à melhor opção. Esta pele, também, pode ser utilizada de maneira imediata ou após conservação em banco de tecidos. Descrevemos neste artigo as principais técnicas para retirada de enxertos dos retalhos traumáticos.

Primary grafting using skin from traumatic flaps is essential in the correct and early treatment of patients with degloving injuries. Split- or full-thickness grafts can be used; however, the literature does not yet provide any indication of the best option. Moreover, this skin also can also be used immediately or after tissue bank storage. This report describes the main techniques for graft removal from traumatic flaps.

Uso de espumas em áreas doadoras de enxertos / Use of polyurethane foam dressings on skin graft donor sites

Introdução: O sucesso de um enxerto de pele é avaliado não apenas pela integração do enxerto em si, mas também pela qualidade da recuperação da área doadora. A despeito de as áreas doadoras de enxertos representarem o melhor local para estudo de cicatrização de feridas, regimes de tratamento, de áreas doadoras, tem sido incompletamente estudados. Objetivo: Avaliação da eficácia de espumas de poliuretano como curativo de áreas doadoras de enxertos. Método: Estudo prospectivo no qual áreas doadoras de enxertos foram tratadas com espumas de poliuretano como alternativa a filmes de acetato de celulose. Resultados: Foram tratados 11 pacientes e catorze áreas doadoras de enxerto. Aderência prolongada (73%) e odor desagradável (45%) foram os problemas encontrados. Os resultados foram considerados insatisfatórios na grande maioria dos casos (73%). Conclusões: O uso de espumas de poliuretano mostrou-se ineficaz, nesse grupo de pacientes, devido à ocorrência de alto índice de complicações.

Introduction: The success of a skin graft is evaluated by not only the integration of the graft itself, but also the quality of the recovery of the donor site. Despite the fact that graft donor sites represent the best place to study wound healing, treatment regimens for donor sites have not been studied extensively. Method: To evaluate the efficiency of polyurethane foam as a dressing for graft donor sites. Methods: We conducted a prospective study in which graft donor sites were treated with polyurethane foam dressing, as an alternative to a cellulose acetate film. Results: We treated 11 patients and 14 donor graft sites. Problems associated with the use of polyurethane foam included prolonged adherence (73%) and an unpleasant odor (45%). The majority of patients reported that they found the dressing to be unsatisfactory (73%). Conclusions: The use of a polyurethane foam was shown to be ineffective as a graft donor site dressing, due to the high rate of associated complications.
