RESUMO

Background and study aims A comparative study was conducted to evaluate the efficacy of argon plasma coagulation (APC) therapy in treating post Roux-en-Y gastric bypass (RYGB) weight regain and the incidence of complications related to this procedure, using a sham treatment group as a control. Patients and methods Forty-one patients with a minimum weight regain of 10 kg and a minimum postoperative time of 36 months were randomized into two groups. Results In the APC group (n = 21), the mean initial weight was 100.4 kg and the mean weight regain was 24.94 kg. In the sham group (n = 20), the mean initial weight was 103.65 kg, and the mean weight regain was 25.18 kg. Anastomotic stenosis occurred only after the first APC session. The results for the comparison of APC with the sham group showed a percentage weight regain loss of 63.95 compared to -.65, and weight loss of 15.02 and -0.57), percentage total weight loss of 14.46 and -0.62, excess weight loss of 54.32 % and -2.34 %), and BMI reduction of 5.38 and -0.21, with P  < 0.0001 for all the comparisons. In the APC group, there was a significant reduction in HbA1c (5.66 % to 4.96 %) and triglycerides (153.20 mg/dL to 132.20 mg/dL). Conclusions This study indicates that APC outlet pouch reduction outperforms sham treatment in terms of weight loss for patients presenting weight regain after RYGB.

RESUMO

INTRODUCTION: Argon plasma coagulation (APC) alone is effective and safe at treating weight regain following Roux-en-Y gastric bypass (RYGB). However, technical details of the treatment vary widely among studies. Therefore, we aimed to create good clinical practice guidelines through a modified Delphi consensus, including experts from the collaborative Bariatric Endoscopy Brazilian group. METHODS: Forty-one locally renowned experts were invited to the consensus by email. Experiences of > 150 APC-treated cases or authorship of relevant articles were the eligibility criteria. An initial questionnaire with short-answer questions was distributed to the experts. The organizing committee converted the responses into statements for an online 2-day voting webinar. Consensus was defined as more than 67% of positive answers. Three consecutive voting rounds were planned with discussion and statement refinements between rounds. RESULTS: Thirty-seven experts fulfilled eligibility criteria and attended the live webinar voting. The total number of patients treated by the panel was 12,349. By the third round, all 79 statements reached consensus. The recommendations include the definition of dilated gastrojejunal anastomosis as ≥ 15 mm, minimum regain of 20% of the lost weight to indicate the APC therapy, 6 to 8 weeks as the ideal interval between ablation sessions, and stopping treatment when the stoma reaches < 12 mm of breadth. CONCLUSIONS: This consensus provides several recommendations based on a highly experienced panel of endoscopists. Although it covers most aspects of the treatment, the level of evidence is low for the majority of the statements. Therefore, bariatric endoscopists should be constantly attentive to new evidence on APC treatment.

RESUMO

PURPOSE: Bariatric endoscopy is a less invasive approach for obesity management, with better efficacy than pharmacological treatment and low morbidity. Endoscopic sleeve gastroplasty (ESG) is the remodeling of the stomach using a suturing device showing technical feasibility, safety, and sustained weight loss. With growing numbers of procedures worldwide, there is a need to standardize the procedure. MATERIALS AND METHODS: A consensus meeting was held in São Caetano do Sul-SP, Brazil, in June 2019, bringing together 47 Brazilian endoscopists with experience in ESG from all regions of the country. Topics on indications and contraindications of the procedure, pre-procedure evaluation and multidisciplinary follow-up, technique and post-procedure follow-up, and training requirements were discussed. An electronic voting was carried, and a consensus was defined as ≥ 70% agreement. RESULTS: The panel's experience consisted of 1828 procedures, with a mean percentage total body weight loss (TBWL) of 18.2% in 1 year. Adverse events happened in 0.8% of the cases, the most common being hematemesis. The selected experts discussed and reached a consensus on several questions concerning patient selection, contraindications for the procedure, technical details such as patient preparation, procedure technique, and patient follow-up. CONCLUSIONS: This consensus establishes practical guidelines for performance of ESG. The experience of 1828 procedures shows the expertise of the selected specialists participating in this consensus statement. The group's experience has a satisfactory weight loss with low adverse events rate. The main points discussed in this paper may serve as a guide for endoscopists performing ESG. Practical recommendations and technique standardization are described.

RESUMO

BACKGROUND: To analyze the results regarding weight loss and complications related to the Spatz3® adjustable intragastric balloon (IGB) in Brazil. METHODS: This randomized prospective study covered patients who had undergone treatment using a Spatz3® adjustable IGB between October 2016 and June 2018 at a private clinic in Rio de Janeiro, Brazil. The patients had a minimum body mass index (BMI) of 27 kg/m2. The study examined complications of Spatz3® treatment and BMI reduction, percentage of total weight loss (%TWL), and % of excess weight loss (%EWL). RESULTS: One hundred eighty patients underwent a Spatz3® balloon implant in the period. The patients were randomly divided into one group in which the Spatz balloon was kept at the same volume (600 mL) throughout treatment (Control Group), and another adjustment group with 250 mL greater volume. The complication rate was 16.14%. No death or major complication occurred during the study. Mean BMI decreased from 39.51 to 32.84 kg/m2 (p < 0.0001), bodyweight from 111.87 to 90.28 kg (p < 0.0001), and excess weight from 41.55 to 22.99 kg (p < 0.0001). The adjustment resulted in greater mean weight loss of 4.35 kg (- 8 to 17.6 kg), and the average time of the procedure was 7.12 ± 1.63 months. The upward adjustment group did not present greater %TWL, %EWL, or BMI reduction when compared with the control group (p = 0.4413, p = 0,9245, p = 0.2729, respectively). CONCLUSION: This study shows that Spatz3® IGB treatment is an effective procedure for weight reduction, with no mortality but higher morbidity compared with traditional IGBs. This procedure also enabled the balloon to stay in place for longer. The efficacy of upward adjustment still requires further confirmation.

RESUMO

BACKGROUND: Endoscopic methods, especially the intragastric balloon (IGB), have been shown to be effective for the treatment of excess weight. This study aimed to assess the tolerance, complications, and efficacy of excess weight treatment with a non-adjustable IGB during 6 months. METHODS: A total of 5874 patients treated with a liquid-filled IGB (600-700 mL) and followed up by a multidisciplinary team were evaluated. Participants presented an initial body mass index (BMI) ≥ 25 kg/m2 and were stratified according to sex and degree of overweight (overweight and obesity grades I, II, and III). RESULTS: The incidence of complications was 7.32% (n = 430): 6.10% (n = 357) early IGB removal, 0.20% (n = 12) gas production inside the balloon, 0.54% (n = 32) leakage, 0.32% (n = 19) pregnancy, 0.07% (n = 4) gastric perforation, 0.05% (n = 3) upper digestive bleeding, 0.01% (n = 1) Wernicke-Korsakoff syndrome due to excessive vomiting, and 0.02% each (n = 1) pancreatitis and esophagus perforation. The 5444 remaining patients (4081 women, 38 ± 38 years) presented a weight loss of 19.13 ± 8.86 kg and a BMI decreased significantly (p < 0.0001) (36.94 ± 5.67 vs. 30.08 ± 5.06 kg/m2). The % total weight loss (%TWL) was 18.42 ± 7.25%, and the % excess weight loss (%EWL) was 65.66 ± 36.24%. The treatment success rate (%TWL ≥ 10%) was 85%. The %EWL was higher in the pre-obese group (122.19%), followed by obesity grades I (76.67%), II (56.01%), and III (45.45%), with p < 0.0001 for each group. %EWL was higher in women (69.71%) than in men (53.39), with p < 0.0001 for each group. There was also a statistical difference between the TWL and EWL groups, with p < 0.001 for all analyses. CONCLUSION: Endoscopic IGB treatment for excess weight is an excellent therapeutic option for patients with different degrees of overweight.

RESUMO

BACKGROUND: Sleeve gastrectomy is a well-standardized surgical treatment for obesity. However, rates of weight regain after sleeve gastrectomy in long-term follow-up are relatively high. This multicenter study is the first to evaluate the use of an endoscopic sleeve gastroplasty (ESG) technique for the management of this population. METHODS: This was a multicenter retrospective study, including patients with weight regain following sleeve gastrectomy who underwent ESG for weight loss. Primary outcomes included absolute weight loss, percent total weight loss (%TWL), change in body mass index (BMI), percent excess weight loss (%EWL) at 6 and 12 months, and safety profile. Clinical success was defined as achieving ≥ 25 % EWL at 1 year, ≤ 5 % serious adverse event (SAE) rate following society-recommended thresholds, and %TWL ≥ 10 %. RESULTS: 34 patients underwent ESG after sleeve gastrectomy. Technical success was 100 %. At 1 year, 82.4 % and 100 % of patients achieved ≥ 10 %TWL and ≥ 25 % EWL, respectively. Mean (SD) %TWL was 13.2 % (3.9) and 18.3 % (5.5), and %EWL was 51.9 % (19.1) and 69.9 % (29.9) at 6 months and 1 year, respectively. Mean (SD) %TWL was 14.2 % (12.5), 19.3 % (5.3), 17.5 % (5.2), and 20.4 % (3.3), and %EWL was 88.5 % (52.8), 84.4 % (22.4), 55.4 % (14.8), and 47.8 % (11.2) for BMI categories of overweight and obesity class I, II, and III, respectively, at 1 year. No predictors of success were identified in the multivariable regression analysis. No SAEs were reported. CONCLUSION: ESG appears to be safe and effective in the management of weight regain following sleeve gastrectomy.

RESUMO

BACKGROUND: The management of laparoscopic sleeve gastrectomy leaks remains a challenge. This can be treated with placement of self-expandable metal stents, which are most effective in the acute and early settings. However, migration is a frequent adverse event (AE). Novel, fully covered stents with a larger proximal flare to limit migration designed specifically to treat postsleeve leaks were recently introduced. OBJECTIVES: The aim of this study was to evaluate the safety and efficacy of a novel stent specifically designed for postsleeve leaks treatment. SETTING: Multicenter retrospective study. METHODS: This is a multicenter study, including patients with acute and early post laparoscopic sleeve gastrectomy leaks, treated with a large bariatric stent. The outcomes include technical success, clinical success, and safety profile. A multivariable regression was performed to assess predictors of success. RESULTS: Thirty-seven patients were included (10 acute and 27 early leaks), with 30 stents in the postpyloric (POST) and 7 in the prepyloric position. Technical success was 100%. Mean stent dwell time was 29.08 days. Clinical success was achieved in 78.37%. Leak duration, leak size, and stent dwell time did not correlate with clinical success. During follow-up, 8 patients had stent migration (21.62%) and all were in a POST position. AE poststent removal were also evaluated (prepyloric: 57.14% vs POST: 33.3%, P = .45). There was no difference between prepyloric and POST position in the severe AE analysis. CONCLUSIONS: This novel, large-caliber, fully covered stent specifically designed for sleeve leaks appears to be effective at treating acute and early leaks. However, the large flanges and long stent length do not appear to reduce migration rate and may be associated with higher overall severe AE rates. Avoiding placement in the POST position may help mitigate migration risk; however, owing to the risk profile this stent should be used with caution.

RESUMO

BACKGROUND AND AIMS: Obesity is a pandemic affecting approximately 700 million adults worldwide, with an additional 2 billion overweight. Endoscopic sleeve gastroplasty (ESG) is a minimally invasive endoscopic bariatric therapy that involves remodeling of the greater curvature in an effort to reduce gastric capacity and delay gastric emptying. A variety of ESG suture patterns has been reported. This study is the first to use a uniform "U" stitch pattern across all centers to simplify technical aspects of the procedure and limit cost. This also uniquely assessed outcomes in all body mass index (BMI) categories and changes in metabolic rate, lean body mass, and adipose tissue composition. METHODS: This is a multicenter analysis of prospectively collected data from 7 centers including patients with overweight and obesity who underwent ESG. Primary outcomes included absolute weight loss, percent total body weight loss (%TWL), change in BMI, and percent excess weight loss (%EWL) at 6 and 12 months in overweight and obese classes I, II, and III. Secondary outcomes included adipose tissue, lean body mass reduction, and metabolic rate analyzed by bioimpedance. Additionally, immediate or delayed adverse events (AEs) were analyzed. Clinical success was defined as achieving ≥25% EWL at 1 year with ≤5% serious AE (SAE) rate following the American Society for Gastrointestinal Endoscopy (ASGE)/American Society for Metabolic and Bariatric Surgery (ASMBS) threshold. RESULTS: A total of 193 patients underwent ESG during the study period. All groups had >10% TWL and >25% EWL at 6 months of follow-up. On average, %TWL was 14.25% ± 5.26% and 15.06% ± 5.22% and the %EWL 56.15% ± 22.93% and 59.41% ± 25.69% at 6 months and 1 year of follow-up, respectively. %TWL was 8.91% ± .3%, 13.92% ± 5.76%, 16.22% ± 7.69%, and 19.01% ± .95% and %EWL 56.21% ± 2.0%, 62.03% ± 27.63%, 54.13% ± 23.46%, and 46.78% ± 2.43% for overweight and obesity classes I, II, and III, respectively, at 1 year. Male sex, age <41 years, and higher BMI were predictors of achieving a TWL ≥10% at 1-year follow-up. There was a significant reduction in adipose tissue from baseline. SAEs occurred in 1.03%, including 2 perigastric collections needing surgery. CONCLUSIONS: ESG appears to be feasible, safe, and effective in the treatment of patients with overweight and obesity according to ASGE/ASMBS thresholds.

RESUMO

A reabilitação oclusal de pacientes parcialmente desdentados com redução da dimensão vertical de oclusão (DVO) representa um grande desafio para o cirurgião-dentista. Normalmente envolve procedimentos complexos, demorados e de elevado custo. A prótese parcial removível (PPR) do tipo overlay representa uma alternativa reabilitadora que pode ser utilizada para esta finalidade. Por meio do relato de um caso clínico, este trabalho teve por objetivo descrever a técnica de utilização da PPR overlay, bem como discutir a viabilidade clínica e efetividade desta modalidade de tratamento. No caso em questão, diagnosticada a redução da DVO, inicialmente a reabilitação oral foi feita de forma provisória, utilizando PPR overlay provisória no arco superior e PPR provisória convencional no arco inferior. O restabelecimento das posições mandibulares possibilitou a reconstrução dos dentes anteriores desgastados com resina composta e a confecção de PPR overlay com recobrimento metálico como tratamento "definitivo". As PPRs de recobrimento (overlays) representam uma excelente e eficiente alternativa no restabelecimento das relações maxilomandibulares. São procedimentos menos onerosos que os procedimentos fixos convencionais, normalmente utilizados na reabilitação de pacientes com diminuição da DVO, mais conservadores e bem indicados para pacientes que tiveram desgastes em função de hábitos parafuncionais.

The occlusal rehabilitation of partially edentulous patients with reduced vertical dimension of occlusion (VDO) represents a great challenge for the dentist. Normally, involving complex, time-consuming and expensive procedures. The removable partial denture (RPD) overlay type represents a rehabilitative alternative that can be used for this purpose. Through the report of a case, this study aimed to describe the use of the RPD overlay technique as well as discuss the clinical feasibility and effectiveness of this treatment modality. In this case, diagnosed the VDO reduction, initially, the oral rehabilitation was made provisionally, using provisory overlay RPD on the upper arch and conventional provisory RPD in the lower arch. The restoration of mandibular positions made possible the reconstruction of the worn anterior teeth with composite resin and the production of the overlay RPD with metallic covering as the "definitive" treatment. The covering RPDs (overlays) are an excellent and efficient alternative on the restoration of the maxillomandibular relations. They are less costly procedures than conventional fixed procedures, normally used in the rehabilitation of patients with decreased VDO, more conservative and well suited for patients who had wear due parafunctions habits.

RESUMO

BACKGROUND: About 90% of type 2 diabetic patients are obese or overweight. The obvious clinical improvement observed with surgeries, such as Roux-en-Y gastric bypass, has opened space for research by different factors than only weight loss, as responsible for the return to euglycemia and reduction of medication use. AIM: To evaluate the efficacy and safety of surgical treatment of diabetes in obese patients with BMI above 35 kg/m2 underwent to gastric bypass, for the control of diabetes, weight loss, improvement of laboratory findings and complications of diabetes. METHOD: The protocol was implemented in three stages: initial, after losing 10% of weight, and after a year. RESULTS: Seventeen patients who have lost weight in 10% were included in the surgical protocol. From the total, 11.8% continued needing medication (p <0.001). The time for weight loss was a month with significant reduction in fasting glucose, HOMA-IR index, insulin, HbA1c, hemoglobin, AST, urea and C-peptide and there was no variation in hematocrit, albumin, ALT and creatinine. With a year of monitoring, the surgical group showed a significant difference in weight, BMI, blood glucose, HbA1c, C-peptide, insulin and HOMA-IR. The percentage of patients with neuropathy (31.3%) was lower than the number of cases at baseline (52.9%) (p> 0.05). CONCLUSION: Gastric bypass with Roux-en-Y derivation is a safe procedure, with good results in control of diabetes type 2 in obese patients with BMI above 35 kg/m2.

RESUMO

BACKGROUND: Strictures of low colorectal anastomosis are increasing by use the anastomotic stapler. There are many kinds of treatments like dilation, transanal rectotomy, and resection with linear or circular stapler. Other methods includes endoscopic knifes, absorbable sutures and laparotomy. The Transanal Endoscopic Microsurgery (TEM) has been used to treat postoperative anastomotic stenosis. CASES REPORT: Three cases of anastomotic strictures after low colorectal anastomosis were treated with TEM with success in medium follow-up. They had a good postoperative evolution without recurrence of symptoms and stenosis. CONCLUSION: The new TEM surgical approach seems to be a safe choice for the treatment of the postoperative colorectal stenosis.

INTRODUÇÃO: Estenoses de anastomoses colônicas baixas estão sendo mais relatadas devido ao maior uso de anastomoses mecânicas. Existem vários processos de tratamento como dilatações, retotomia transanal e ressecções com re-anastomoses mecânicas. Outros métodos incluem secções endoscópicas, secções com anastomoses com suturas absorvíveis e laparotomia. A Microcirurgia Endoscópica Transanal (TEM) está sendo proposta para o tratamento das estenoses anastomóticas. RELATO DOS CASOS: Três casos de estenoses anastomóticas foram tratados pela TEM com bom resultado em relação ao seguimento a médio prazo sem recurrência de sintomas. CONCLUSÃO: A TEM parece ser boa opção para o tratamento das estenoses resultantes das anastomoses coloretais baixas.

RESUMO

RACIONAL: A Microcirurgia Endoscópica Transanal (TEM) corresponde a um dos mais recentes avanços no tratamento para lesões retais benignas e malignas. OBJETIVO: Determinar o custo da TEM no Hospital de Clínicas da Universidade Federal do Paraná, comparando-o ao da amputação abdômino-perineal do reto e da retossigmoidectomia anterior, estabelecendo parâmetros de custo-efetividade no âmbito do Sistema Único de Saúde. MÉTODOS: Estudo observacional, prospectivo e de coorte da avaliação dos custos dos três procedimentos cirúrgicos citados, enfocando gastos laboratoriais, com medicamentos e internação. Foram incluídos 74 pacientes, 27 submetidos à TEM, 29 à retossigmoidectomia anterior e 18 à amputação abdômino-perineal. RESULTADOS: Com relação à idade, não se observa diferença estatisticamente significativa entre os grupos. O grupo da TEM apresentou o menor tempo de internação (5,51 dias) comparado à retossigmoidectomia anterior (20,41) e à amputação abdômino-perineal (18,33). Quando se consideram os custos laboratoriais, de medicamentos e de diárias hospitalares, observam-se diferenças significantes entre os três procedimentos com custo muito inferior no grupo da TEM, cerca de 2,5 a 4 vezes menor na comparação global (R$ 1.326,71 vs R$ 5.427,16 vs R$ 4.310,20, respectivamente). CONLUSÃO: As vantagens da TEM se mostram evidentes no que tange a custos de internação e permanência hospitalar, com redução significativa quando comparado às técnicas convencionais.

BACKGROUND: Transanal Endoscopic Microsurgery (TEM) corresponds to one of the most recent advances in treating bening and malignant rectal lesions. AIM: To determine the cost of TEM at the Hospital de Clínicas of the Federal University of Paraná, and compare it to the cost of a perineal-abdominal amputation of the rectum and of an anterior rectosigmoidectomy, therefore establishing cost-effective parameters with regards to the "Sistema Único de Saúde”. METHODS: Observational and prospective study pertaining cost evaluation of the three surgical procedures pointed above, focusing on laboratory expenses with drugs and hospitalization. Seventy four patients were included in the study, and of these 27 were submitted to TEM, 29 to anterior rectosigmoidectomy and 18 to perineal-abdominal amputation of the rectum. RESULTS: With regards to age, no significant statistical difference was observed. The group who underwent TEM presented the lowest admission period (5,51 days) when compared to the anterior rectosigmoidectomy (20,41) and to the perineal-abdominal amputation of the rectum (18,33). With regards to laboratory expenses, drug and hospital daily rates, significant statistical differences were observed between the three surgical procedures. The TEM group had the lowest cost, approximately 2.5 to four times smaller in the overall comparison (R$ 1,326.71 vs R$ 5,427.16 vs R$ 4,310.20 respectively). CONCLUSION: TEM advantages are evident through admission and hospital stay costs, with significant reduction when compared to conventional techniques.

Ausência de dor pós-operatória foi observada em 82,5% e todos se mostraram capazes de deambular no 1º dia do pós-operatório. O retorno às atividades habituais deu-se em média sete dias após o procedimento. Somente cinco pacientes (14,70%) apresentaram incontinência fecal transitória, não maior que uma semana. Três pacientes (8,82%) necessitaram de re-internação, sendo dois por tumores residuais e outro por recidiva tumoral. Dois pacientes (5,88%) referiram modificação temporária na vida sexual após a cirurgia e 97,05% indicariam a TEM a um familiar ou amigo. O período médio de internação foi de três dias. CONCLUSÃO: Os pacientes apresentaram boa evolução, com pouca dor pós-operatória, curto período de internação e baixo índice de complicações, mostrando satisfação e adequada qualidade de vida com a TEM.

BACKGROUND: Transanal Endoscopic Microsurgery (TEM) is a minimal invasive procedure for the treatment of rectal tumors. Nowadays there has been an increasing medical interest regarding quantitative measurements pertaining quality of life. AIM: To evaluate life quality of patients submitted to TEM at Hospital de Clínicas of the Federal University of Paraná in the Department of Surgery of the Digestive Tract. METHODS: A prospective observational cohort study was done to evaluate the quality of life after TEM. Thirty-four patients answered a questionnaire composed of 14 questions concerning postoperative and labor issues. Questions concerned primarily about: informed consent; pain felt after surgery; patients capacity to walk during the postoperative state; period of return to normal activities; satisfaction regarding the absence of postoperative scars; postoperative incontinence, as well as the recommendation of this surgery to family members or friends. RESULTS: All thirty-four patients claimed to be adequately informed about the procedure. The absence of postoperative pain was observed in 82.5 %, and all demonstrated the capacity to walk in the first postoperative day. In average, returning to normal activities began after the seventh day of surgery. Only five patients (14.70%) experimented transitory fecal incontinence, enduring no longer than a week. Three patients (8.82%) were later readmitted to the hospital: two with residual tumors and the other for tumor recurrence. Two patients (5.88%) complained about temporary modification in his/her sexual life after the surgery, and 97.05% would indicate TEM for his/her family members or friends. The average time period of admission was of three days. CONCLUSION: Patients presented a good evolution, with little postoperative pain, and a low complication index, demonstrating satisfactory and adequate quality of life after TEM.

RESUMO

INTRODUCTION: The large use of plants in the prevention and treatment of different diseases is a milenar practice. In Brazil due to it's rich flora there is a huge material for research and use in popular medicine. The babassu (Orbignya phalerata) is a native tree from North of the Brazil and has a high concentration at the State of Maranhão. The powder of it's mesocarp is known as amid, and has been used as meal and medication due to the known activity against antiinflammatory reaction, pain, pyrexia and immunomodulation. PURPOSE: To analyze the effect of mesocarp of Orbignya phalerata (babassu) in gastric wound healing in rats under morphologic and tensiometric aspects. METHOD: Forty Wistar rats, male, adults were submitted to a longitudinal incision of 1 cm in the gastric body and sutured with separated stitches of polypropylene 6.0. After this common procedure the animals were allocated in the aleatory way in two groups Orbignya (GO) and Control (GC) with 20 animals each one. In the GO was used intraperitoneal doses of 50 mg/kh of Orbignya phalerata extract and in the GC water 1 ml/kg. Each group was divided in two subgroups of ten rats according to the period of death, at 3rd and 7th post-operative days. After the death, the abdominal cavity was evaluated and the stomach withdrawn. For the comparative analysis between the groups the macroscopic and histological parameters of wound healing were utilized. RESULTS: There were no abscess, fistulae and haematom in the animals of the study. Abdominal adhesions were observed in both groups of the animals at 3rd and 7th post-operative days. Dehiscence of the gastrography was identified in one 3rd day rat of subgroups GO. The resistance to air insufflation was higher in GO 3rd day (p=0.087). The analysis of histological parameters showed statistical difference related to wound coaptation in favor to subgroup GO 7th post-operative day. CONCLUSIONS: The extract of mesocarp of Orbignya phalerata in dose and path utilized positively interfered on the gastrography when compared with control group in animals at 7th post-operative day.

RESUMO

INTRODUÇÃO: A utilização de plantas na prevenção e no tratamento de doenças é prática milenar. O babaçu (Orbignya phalerata) é uma palmeira nativa do meio norte do Brasil, tendo sua maior concentração no Estdo do Maranhão. O pó do mesocarpo do coco babaçu é popularmente conhecido como amido e tem sido usado como alimento e como medicamento por apresentar atividade antiinflamatória, imunomoduladora, analgésica e antipirética. OBJETIVO: Avaliar o efeito do extrato aquoso do mesocarpo de Orbignya phalerata na cicatrização do estômago em ratos, sob aspectos morfológico e tensiométrico. MÉTODOS: Quarenta ratos da linhagem Wistar, adultos, machos foram submetidos à incisão longitudinal de 1cm no corpo gástrico e síntese em plano único com pontos separados de polipropilene 6-0. Após este procedimento comum, os animais foram distribuídos aleatoriamente em dois grupos, Orbignya (GO) e Controle (GC), contendo 20 animais cada. No GO utilizou-se dose única intra-peritoneal de extrato aquoso da planta na dose de 50mg/kg e no GC, água destilada, 1ml/kg de peso. Cada grupo foi dividido em dois subgrupos de 10, conforme o dia da morte dos animais, nos 3º e 7º dias do período pós-operatório. Após a morte, foi realizado o inventário da cavidade abdominal e procedeu-se a retirada do estômago, com posterior avaliação tensiométrica e análise miccccroscópica. Na análise comparativa entre os dois grupos utilizou parâmetros macroscópicos e microscópicos da cicatrização. RESULTADOS: Não foram detectados abscessos, fístulas ou hematomas em nenhum animal. Houve aderências abdominais nos animais dos 3º e 7º dias do período pós-operatório nos dois grupos. Houve deiscência da gastrorrafia em um rato do sub-grupo GO morto no 3º dia. A resistência à insuflação de ar atmosférico foi maior no GC de três dias (p=0,087). A análise dos parâmetros histológicos demonstrou diferença estatisticamente significativa apenas quanto à coaptação das bordas, favorecendo o sub-grupo GO de sete dias...(AU)

INTRODUCTION: The large use of plants in the prevention and treatment of different diseases is a milenar practice. In Brazil due to it's rich flora there is a huge material for research and use in popular medicine. The babassu (Orbignya phalerata) is a native tree from North of the Brazil and has a high concentration at the State of Maranhão. The powder of it's mesocarp is known as amid, and has been used as meal and medication due to the known activity against antiflammatory reaction, pain, pyrexia and immunomodulation. PURPOSE: To analyze the effect of mesocarp of Orbignya phalerata (babassu) in gastric wound healing in rats under morphologic and tensiometric aspects. METHOD: Forty Wistar rats, male, adults were submitted to a longitudinal incision of 1 cm in the gastric body and sutured with separated stitches of polypropilene 6.0. After this common procedure the animals were allocated in the aleatory way in two groups Orbignya (GO) and Control (GC) with 20 animals each one. In the GO was used intraperitoneal doses of 50mg/kh of Orbignya phalerata extract and in the GC water 1ml/Kg. Each group was divided in two subgroups of ten rats according to the period of death, at 3rd and 7th post-operative days. After the death, the abdominal cavity was evaluated and the stomach withdrawn. For the comparative analysis between the groups the macroscopic and histological parameters of wound healing were utilized. RESULTS: There were no abscess, fistulae and haematom in the animals of the study. Abdominal adhesions were observed in both groups of the animals at 3rd and 7th post-operative days. Dehiscence of the gastrorraphy was identified in one 3rd day rat of subgroups GO. The resistance to air insufflation was higher in GO 3rd day (p=0,087). The analysis of histological parameters showed statistical difference related to wound coaptation in favor to subgroup GO 7th post-operative day...(AU)

RESUMO

PURPOSE: The objective of the present study was to monitor the process of second intention skin wound healing in rats with jaundice. METHODS: The study was divided into two steps. In the first, obstructive jaundice was induced in 68 male rats to investigate the biochemical changes and to determine the ideal time for the study of healing In the second step, 54 rats were divided into two groups: control (normal) and experimental (jaundiced). Seventy-two hours after jaundice induction, a standardized wound was produced in the dorsum by removing the skin and the subcutaneous net, whose contraction was assessed on the 3rd, 7th, 10th and 14th day and monitored with a computer program. After sacrifice, the tissue was submitted to histopathologic analysis. RESULTS: The most marked biochemical changes were detected between the 3rd and 5th day. The reduction of he wound area was slower in the jaundice group at all 4 time points studied (p3=0.0366, p7=0.0054, p1o=0.0000. p,4=0.0000). Collagen concentration was lower in the wound of jaundiced animals (p3=0.0000. p7 0.0000. pI4 0.0000). CONCLUSION: Jaundice delays collagen deposition and maturation and wound contraction in wounds left to heal by second intention wound healing in rats.
