Ambulatory surgery in proctology: retrospective analysis of 1 031 cases

Introduction: The number of ambulatory surgeries accomplished in hospitals, as in private clinics, grows each day, with this increase having been observed principally in the last two decades. In many countries, such as France, ambulatory surgeries have predominated in relation to those in hospitals. Objective: To evaluate retrospectively 1 031 cases of patients operated on in the Ambulatory Surgery Service of CH. in the School of Medicine at Botucatu. Material and method: Retrospectively, 1 031 clinical cases of orificial pathologies operated on in the service were studied, analyzing the distribution by age group, sex, pathologies and postoperative complications. Result: We note predominance of patients aged less than 45 years (56.6%), discrete prevalence of males (51.2%), with hemorrhoidal disease (60%) being the principal affliction, with pain and bleeding being the most frequent complications (3.2%). Conclusions: The results obtained demonstrate that ambulatory procedures in proctology can be accomplished in a safe and systematic manner at low cost with advantages and fewer complications in relation to procedures completed in a hospitalization regime.

Preoperative and Postoperative Nutritional Evaluation in Patients with Non-advanced Megaesophagus

Megaesophagus, an affection characterized by aperistalses of the esophageal body and deficient relaxation of lower esophageal sphincter, has disphagia as main symptom. The aim of this study was to evaluate the nutritional status of patients with non advanced megaesophagus in pre and post-operative periods of cardiomyotomy. Ten patients were evaluated at 5 moments (pre-operative - M 1 and post-operative - 1, 3, 6 ant 12 months after surgery). The anthropometric, hematimetric and biochemical parameters were studied in the 5 moments. Conclusions: 1. Most 017 the patients with non-advanced megaesophagus are eutrophic; 2. Surgical treatment determines an improvement in nutritional status and an increase in HDL cholesterol values.

Cirurgia ambulatorial em proctologia: análise retrospectiva de 437 casos

RACIONAL: O número de cirurgias ambulatoriais realizadas em hospitais, como em clínicas particulares, cresce a cada dia. Hoje, em alguns países, como a França, há predomínio das cirurgias ambulatoriais em relação às hospitalares. OBJETIVO: Avaliar retrospectivamente os pacientes operados no Serviço de Cirurgia Ambulatorial do Hospital das Clínicas da Faculdade de Medicina de Botucatu, SP. CASUÍSTICA E MÉTODO: Foram estudados retrospectivamente 437 casos clínicos de patologias orificiais, analisando a distribuição por faixa etária, por sexo, por patologias e as complicações pós-operatórias. RESULTADOS: Notou-se predomínio de pacientes com idade inferior a 45 anos (62,8%), prevalência do sexo feminino (56%), sendo a doença hemorroidária (45,1%) a principal patologia e a dor e sangramento as complicações mais freqüentes (9,8% e 7,3%). CONCLUSÕES: Os resultados satisfatórios observados demonstram a possibilidade de realização, em ambulatório, de diversos procedimentos simples em patologias anorretais freqüentes, a baixo custo e poucas complicações, sendo estas não superiores às observadas em cirurgia hospitalar.

Comparison between actual and predicted postoperative stair-climbing test, walk test and spirometric values in patients undergoing lung resection

OBJETIVO: Verificar se os testes: Volume Expiratório Forçado no 1º segundo (VEF1), Teste de Caminhada de 6 minutos (TC6) e Teste de Escada (TE) se alteram proporcionalmente ao pulmão funcionante ressecado. MÉTODOS: Foram incluídos pacientes candidatos a toracotomia para ressecção pulmonar. No pré-operatório (pré) e no mínimo três meses após a cirurgia (pós), realizaram espirometria, TC6 e TE. O TE foi realizado em escada com 12,16m de altura. O tempo para subir todos os degraus o mais rápido possível foi chamado tempo de escada (tTE). Os cálculos dos valores dos testes preditos para o pós-operatório (ppo) foram realizados conforme o número de segmentos funcionantes perdidos. Os valores pré, ppo e pós foram comparados entre si para cada teste. Estatística: foi utilizada a análise de variância para medidas repetidas (ANOVA), com significância de 5%. RESULTADOS: Foram estudados 40 pacientes. A ressecção pulmonar variou desde o ganho de dois segmentos funcionantes até a perda de 9. Os valores pré, ppo e pós foram respectivamente: VEF1 -pré = 2,6±0,8L, ppo = 2,3±0,8L, pós = 2,3±0,8L (VEF1pré > VEF1ppo = VEF1pós), TC6-pré = 604±63m, ppo = 529±103m, pós = 599±74m (TC6pré = TC6pós > TC6ppo), tTE-pré = 32,9±7,6s, ppo = 37,8±12,1s, pós = 33,7±8,5s (tTEpré = tTEpós < tTEppo). CONCLUSÃO: Nas ressecções pulmonares, este grupo de pacientes perdeu função pulmonar medida através da espirometria, mas não perdeu a capacidade de exercício, medida através dos testes de escada e caminhada.

Avaliação radiográfica de cães com displasia coxofemoral tratados pela sinfisiodese púbica

Avaliou-se a progressão dos sinais radiográficos de cães com displasia coxofemoral ou potencialmente displásicos tratados pela técnica da sinfisiodese púbica. Foram utilizados 14 cães, seis machos e oito fêmeas, com idades entre quatro e seis meses. Após exame físico, procedeu-se ao exame radiográfico para avaliação da articulação coxofemoral, segundo padrão estabelecido pelo Colégio Brasileiro de Radiologia Veterinária. Três deles foram também avaliados pelo método PennHIP. Pelo histórico clínico, nove (64%) animais foram trazidos por manifestarem sinais de dificuldade locomotora com os membros pélvicos, manifestada especialmente por claudicação unilateral ou bilateral e dificuldade de se levantar. Cinco (36%) cães não tinham qualquer sinal clínico, e em quatro (29%) realizou-se o exame radiográfico como prevenção. O sinal físico mais evidente foi dor à palpação da articulação coxofemoral, e dois (14%) cães apresentaram sinal de Ortolani positivo. Com exceção de um cão que apresentou infecção nos pontos cutâneos, todos os demais evoluíram sem complicações no período pós-operatório. Radiograficamente houve progressão das lesões articulares em seis (43%) animais e oito (57%) mantiveram a classificação inicial. Concluiu-se que cães tratados pela sinfisiodese púbica não apresentam melhora dos sinais radiográficos iniciais.

Analgesic efficacy of perioperative use of vedaprofen, tramadol or their combination in cats undergoing ovariohysterectomy

The analgesic efficacy of tramadol and/or vedaprofen was evaluated in cats submitted for elective ovariohysterectomy, using a randomised double blind placebo controlled design. Forty adult female cats (3.0 +/- 0.32 kg; 1.8 +/- 0.7 years) were distributed into four groups. Vedaprofen PO (0.5 mg/kg), tramadol SC (2 mg/kg), both, or placebo was administered 1 h before surgery and every 24 and 8 h, respectively, for 72 h after surgery. Pain score evaluated by interactive visual analogue and composite pain score and hyperalgesia by the von Frey filament test were recorded at 1, 2, 4, 6, 8, 12, 24, 28, 32, 48, 52, 56, 72, 96 h and on the 7th day after surgery. Animals treated with combined vedaprofen and tramadol treatment did not need rescue analgesia, did not develop hyperalgesia, and their serum cortisol concentrations and pain scores were lower than placebo until 24 and 72 h after surgery, respectively. Combined vedaprofen and tramadol treatment provided more effective postoperative analgesia and prevented hyperalgesia than when used on their own. Multimodal technique is a superior method of treating pain after feline ovariohysterectomy. This work also provides evidence for the benefits of analgesia for up to 3 days following ovariohysterectomy. (C) 2008 ESFM and AAFP. Published by Elsevier Ltd. All rights reserved.

Correction of a Mucogingival Defect Using an Implant-Retained Postoperative Stent in a Severely Resorbed Mandible: Case Report

This case report describes a technique that uses a palatal mucosal graft and an acrylic resin postoperative stent in an attempt to increase the layer of keratinized tissue around osseointegrated implants in an atrophic mandible. During second-stage surgery a split-thickness labial flap is reflected and apically repositioned by being sutured onto the periosteum and connective tissue. A palatal mucosal graft is then sutured onto the recipient site. The stent is worn for at least 4 weeks following surgery. This procedure helps to eliminate mobility of the mucosa in the area, deepen the vestibule, and prevent muscle reinsertion. (Int J Periodontics Restorative Dent 2008;28:617-623.)

A modified approach for vestibuloplasty in severely resorbed mandible using an implant-retained postoperative stent: a case report

Background. Severely resorbed mandibles often present a short band of keratinized tissue associated with a shallow vestibule. As a result, prominent muscle insertions are present, especially in the mental region of the mandible. This case report describes the deepening of the vestibular sulcus in an atrophic mandible by combining free gingival grafts harvested from the palate and a postoperative acrylic resin stent screwed on osseointegrated implants placed at the anterior region of the mandible.Study design. During the second-stage surgery, a split-thickness labial flap was reflected and apically sutured onto the periosteum. Two free gingival grafts were obtained and then sutured at this recipient site. A previously custom-made acrylic stent was then screwed onto the most distally positioned implants. To document the procedure's stability over time, a metal ball was placed in the most apical part of the vestibule and standardized cephalometric radiographs were taken before and 6 months after the procedure. Linear measurements of vestibular depths over the observation time were realized using specific software for radiographic analysis.Results. The proposed technique augmented the band of attached masticatory mucosa, deepened the vestibule and prevented the muscle reinsertion. The difference between the 2 measurements of vestibular depths was 9.39 mm (initial 20.88 mm, final 11.49 mm) after a 6-month postoperative period.Conclusion. The technique, in combination with palatal mucosal graft and use of a postoperative stent, decreased the pull of mentalis muscle and provided a peri-implantally stable soft tissue around implants.

Clinical assessment of postoperative sensitivity in posterior composite restorations

This incidence of postoperative sensitivity was evaluated in resin-based posterior restorations. Two hundred and ninety-two direct restorations were evaluated in premolars and molars. A total of 143 Class I and 149 Class 11 restorations (MO/OD and MOD) were placed in patients ranging in age from 30 to 50 years. After the cavity preparations were completed, a rubber dam was placed, and the preparations were restored using a total-etch system (Prime & Bond NT) and a resin-based restorative material (TPH Spectrum). The patients were contacted after 24 hours and 7, 30 and 90 days postoperatively and questioned regarding the presence of sensitivity and the stimuli that triggered that sensitivity. The Chi-square and Fisher's Exact Test were used for statistical analysis. Evaluation at 24 hours after restorative treatment revealed statistically significant differences among the types of cavity preparations restored and the occurrence of postoperative sensitivity (p=0.0003), with a higher frequency of sensitivity in Class H MOD restorations (26%), followed by Class II MO/DO (15%) and Class I restorations (5%). At 7, 30 and 90 days after restorative treatment, there was a decrease in the occurrence of sensitivity for all groups. The percentage of sensitivity among the groups was not significantly different. This study shows that the occurrence of sensitivity is correlated with the complexity of the restoration.

Maxillo-mandibular counter-clockwise rotation and mandibular advancement with TMJ Concepts (R) total joint prostheses Part III - Pain and dysfunction outcomes

47 end-stage TMJ patients with high occlusal plane angulation, treated with TMJ custom-fitted total joint prostheses and simultaneous maxillo-mandibular counter-clockwise rotation were evaluated for pain and dysfunction presurgery (T1) and at the longest follow-up (T2). Patients subjectively rated their facial pain/headache, TMJ pain, jaw function, diet and disability. Objective functional changes were determined by measuring maximum interincisal opening (MIO) and laterotrusive movements. Patients were divided according to the number of previous failed TMJ surgeries: Group 1 (0-1), Group 2 (2 or more). Significant subjective pain and dysfunction improvements (37-52%) were observed (<0.001). MIO increased 14% but lateral excursion decreased 60%. The groups presented similar absolute changes, but Group 2 showed more dysfunction at T1 and T2. For patients who did not receive fat grafts around the prostheses and had previous failure of proplast/teflon and or silastic TMJ implants, more than half required surgery for TMJ debridement and removal of foreign body giant cell reaction and heterotopic bone formation. End-stage TMJ patients can be treated in one operation with TMJ custom-made total joint prostheses and maxillo-mandibular counter-clockwise rotation, for correction of dentofacial deformity and improvement in pain and TMJ dysfunction; Group 1 patients had better results than Group 2 patients.

Therapeutic Effects of Low-Level Laser Therapy After Premolar Extraction in Adolescents: A Randomized Double-Blind Clinical Trial

Objective: The purpose of this study was to evaluate the effect of low-level laser therapy (LLLT) on wound healing process and pain levels after premolar extraction in adolescents. Background data: The advantage of using LLLT in oral surgeries is the reduction of inflammation and postoperative discomfort; however, the optimal dosing parameters and treatment effects in surgical procedures are inconclusive. Methods: A double-blind, randomized, controlled clinical trial was conducted with 14 patients who were to undergo surgical removal of premolars. Patients were randomly allocated to the LLLT (test) group and placebo (control) group. Patients in the test group received 5.1 J (60 J/cm(2)) of energy density of a gallium-aluminum-arsenide (GaAlAs) diode laser (wavelength, 830 nm; output power, 0.1 W) at three different points intraorally, 1 cm from the target tissue immediately and at 48 and 72 h after the surgical procedure. For patients in the placebo group, the laser device was applied to the same points without activating the hand piece. The wound healing process was evaluated by an independent examiner by visual inspection with the support of digital photographs at baseline and 2, 7, and 15 days postoperatively. Patients recorded the degree of pain using the visual analogue scale (VAS). Results: Compared with the placebo group, the test group showed a lower intensity of pain, but this difference was not statistically significant at any time point. The wound healing process was similar in both groups. Conclusions: Within the limitations of this study, the LLLT parameters used neither increased the wound healing process nor significantly decreased pain intensity after premolar extraction in adolescents.

Medical conditions and body pain in patients presenting orofacial pain

OBJETIVO: Verificar a frequência de problemas médicos autorrelatados e a frequência de áreas de dor no corpo em pacientes com dor orofacial, comparando-os a pacientes submetidos a tratamento odontológico de rotina. MÉTODOS: Os dados foram coletados dos arquivos da Clínica de Dor Orofacial (Grupo A, n=319) e de clínicas de tratamento odontológico rotineiro (Grupo B, n=84) da Faculdade de Odontologia de Araraquara, São Paulo, Brasil. Os indivíduos responderam a questionários e preencheram um mapa corporal indicando os locais de dor. RESULTADOS: O teste de Mann-Whitney demonstrou que o Grupo A apresentou uma média de relatos de problemas médicos superior ao Grupo B (p=0,004). Para ambos os grupos, o teste de correlação de Pearson demonstrou correlação positiva entre os problemas médicos e a frequência de áreas dolorosas (respectivamente, 0,478, p=0,001 e 0,246, p=0,000). CONCLUSÕES: O Grupo A relatou maior número de problemas médicos e houve correlação positiva entre a frequência desses problemas e a de áreas de dor para ambos os grupos.
