RESUMO

The aim of our study is to evaluate the value of Argon Plasma Coagulation in the treatment of gastrointestinal vascular abnormalities. Patients and methods: This is a descriptive and analytical retrospective study, from January 2009 to September 2020. 198 patients who have benefited from treatment with Argon Plasma Coagulation for vascular anomalies of the digestive tract divided into 2 groups: -Group A: Patients with radial rectitis lesions (n = 107). -Group B: Patients with lesions of digestive angiodysplasia (n = 91). Results: The mean age of our patients was 64.95 ± 9.88 years [43 - 83] in group A, while in group B the mean age was 65.19 ± 14.29 years [40 - 91] with a clear male predominance in 72.5%. The majority of patients in group A were followed for prostate cancer in 33,8%, and 26.3% of patients in group B had chronic renal failure, followed by stomach cancer in 15.8%, and esophageal cancer in 10.5%. Clinical symptomatology was dominated by rectories in 40.2% in group A versus 46.8% in group B. Rectal involvement was dominated in group A in 98.1%, whereas in group B the lesions were mainly located in the stomach in 60.5%. The endoscopic evolution was favorable in all our patients with a clear improvement of rectal lesions and digestive angiodysplasia lesions. The total complication rate in our series was nil. Conclusion: Plasma Argon coagulation is a very effective method in the endoscopic treatment of digestive haemorrhages with good tolerability and a low complication rate. (AU)

RESUMO

BACKGROUND: This study performed a meta-analysis to compare the safety and efficacy of argon plasma coagulation (APC) concerning suture (SUT) and surgery (SUR). METHODS: The One-Way tests were applied, with p <0.05 significant. The value of R2 was analyzed (heterogeneity), and the risk of bias of articles was evaluated. RESULTS: A total of 34 studies were found, eight about APC, twenty about SUT, and six about SUR. For the percentage of Weight Loss Regained (%WLR), the means for APC, SUT, and SUR were 19.39 ± 10.94, 26.06 ± 16.71, and 17.05 ± 9.85, and for success rate (%SR), the means were 89.75 ± 16.75, 86.80 ± 11.44, and 76.00 ± 21.57, respectively with p >0.05, with R2 ≥ 50%. CONCLUSION: The APC proved to be efficient and safe like the other techniques.

RESUMO

Abstract Objective Extended curettage with adjuvants of giant cell tumors of bone is associated with a lower rate of recurrence of the tumor while preserving the adjacent joint. The present study was conducted to estimate the recurrence rate and functional outcome after using argon beam as an adjuvant for extended curettage. Methods We selected 50 patients with giant cell tumors, meeting all the inclusion criteria, who underwent extended curettage using high speed burr and argon beam photocoagulation between July 2016 to January 2019. On their follow-up visit, they were assessed for any complaints of pain and signs like tenderness, locally raised temperature, and decreased range of motion of the adjacent joint. Radiologically, the patients were assessed for any increased lucency around the cement mantle and uptake of the subarticular graft. Musculoskeletal Tumor Society Score (MSTS) was administered to the patients, and range of motion of the adjacent joint was compared with the contralateral joint. Results Recurrence was found in 4 patients, that is, an 8% recurrence rate. Twenty-six out of 28 patients with a tumor in the lower limb had a grade-5 weight bearing status 6 months from the surgery, and their range of motion was comparable to contralateral healthy joint with an average MSTS score of 27 (18-30). Conclusion Extended curettage of giant cell tumors using argon beam coagulation is associated with low recurrence rates of the tumor and is an effective modality in the treatment of these tumors besides having a functional outcome comparable to the healthy limb.


Resumo Objetivo A curetagem estendida com adjuvantes de tumores de células gigantes do osso está associada a uma menor taxa de recidiva da neoplasia e à preservação da articulação adjacente. Este estudo foi feito para estimar a taxa de recidiva e o resultado funcional após o uso de plasma de argônio como adjuvante à curetagem estendida. Métodos Cinquenta pacientes com tumores de células gigantes que atendiam a todos os critérios de inclusão foram selecionados para o estudo e submetidos à curetagem estendida com broca de alta velocidade e fotocoagulação com plasma de argônio entre julho de 2016 e janeiro de 2019. À consulta de acompanhamento, os pacientes foram avaliados quanto a quaisquer queixas de dor e sinais como sensibilidade, aumento local da temperatura e diminuição da amplitude de movimento da articulação adjacente. Radiologicamente, os pacientes foram avaliados quanto à presença de qualquer aumento de radiotransparência ao redor do manto de cimento e incorporação do enxerto subarticular. O questionário Musculoskeletal Tumor Society Score (MSTS) foi administrado aos pacientes e a amplitude de movimentação da articulação adjacente foi comparada à articulação contralateral. Resultados Quatro pacientes apresentaram recidiva, o que corresponde a uma taxa de 8%. Seis meses após a cirurgia, 26 de 28 pacientes com tumor no membro inferior tinham capacidade de sustentação de peso de grau 5 e amplitude de movimento comparável à articulação saudável contralateral, com pontuação MSTS média de 27 (intervalo de 18 a 30). Conclusão A curetagem estendida de tumores de células gigantes com coagulação por plasma de argônio está associada a baixas taxas de recidiva da neoplasia; é uma modalidade eficaz no tratamento desses tumores e o resultado funcional é comparável ao do membro saudável.

RESUMO

RESUMEN Introducción: El esófago de Barrett es una condición esofágica adquirida, que puede evolucionar a un adenocarcinoma. Con el paso de los años, la terapia endoscópica ha remplazado la cirugía en el tratamiento de esta afección. Objetivos: Mostrar los resultados de la aplicación de la técnica de resección endoscópica de la mucosa y la ablación con Hibrid-APC en pacientes portadores de esófago de Barrett con displasia de bajo o alto grado. Métodos: Se realizó un estudio descriptivo y retrospectivo en 29 pacientes entre los años 2014-2019, en el Servicio de endoscopias del Centro Nacional de Cirugía de Mínimo Acceso. Se estudiaron variables sociodemográficas, se estableció la clasificación endoscópica del esófago de Barrett, se describieron las características de la lesión, el diagnóstico histológico, la terapéutica endoscópica, la presencia de complicaciones, la resección incompleta y recidiva. Se aplicaron técnicas de estadística descriptiva y métodos no paramétricos. Resultados: Predominó el sexo masculino (58,62 %) y el grupo de 41-60 años (58,62 %). El segmento corto con lesiones planas y el largo con lesiones elevadas fueron más frecuentes (37,93 %). Se realizaron 15 resecciones y 14 ablaciones con Hibrid-APC; se observó una estenosis como complicación de la resección endoscópica de la mucosa y recidivas con ambas técnicas (5 pacientes, 17 %), tres relacionadas con la resección y dos con el Hibrid-APC. El Hibrid-APC alcanzó una efectividad terapéutica del 85,71 % y la resección del 80 %. Conclusiones: El tratamiento endoscópico con displasia de bajo y alto grado, mostró ser un procedimiento efectivo y seguro, con bajo porciento de complicaciones y recidivas.


ABSTRACT Introduction: Barrett's esophagus is an acquired esophageal condition that can evolve into an adenocarcinoma. Over the years, endoscopic therapy has replaced surgery in the treatment of this condition. Objectives: to show the results of the application of the endoscopic mucosal resection and Hybrid-APC ablation technique in patients with Barrett's esophagus with low-grade or high-grade dysplasia. Methods: a descriptive and retrospective study was carried out in 29 patients between 2014 and 2019, in the Endoscopy service of the National Center for Minimal Access Surgery. Social and demographic variables were studied; endoscopic classification of Barrett's esophagus was established, as well as the characteristics of the lesion, histological diagnosis, endoscopic therapy, the presence of complications, incomplete resection and recurrence were described. Descriptive statistics techniques and non-parametric methods were applied. Results: male gender (58.62%) and the group aged 41-60 years (58.62%) predominated. The short segment with flat lesions and the long segment with raised lesions were more frequent (37.93%). A number of 15 resections and 14 ablations were performed with Hybrid-APC; one stricture was observed as a complication of endoscopic mucosal resection and recurrences with both techniques (5 patients, 17%), three related to resection and two to Hybrid-APC. The Hybrid-APC achieved a therapeutic effectiveness of 85.71% and the resection one of 80%. Conclusions: endoscopic treatment with low- and high-grade dysplasia proved to be an effective and safe procedure, with a low percentage of complications and recurrences.

RESUMO

Abstract Background Argon plasma coagulation (APC) is a non-tactile ablative therapy that helps to stop rectal bleeding in patients who have developed actinic proctitis after exposure to radiotherapy. This approach seems to be more effective than medications or surgical procedures. Objective To review the literature to verify the effectiveness of APC in the treatment of patients with actinic proctitis induced by radiation therapies. Methods A systematic search was conducted on the following databases: MEDLINE/PubMed, LILACS, SCIELO, and the Cochrane Central Register of Controlled Trials. We identified 81 studies, and 5 of them fulfilled the inclusion criteria. Results In the articles included, a total of 236 patients were evaluated. Most of them were men (67.7%) with a mean age of 66.6 years. Prostate cancer was the main cause of actinic proctitis (67.3%), and control of the bleeding was achieved in 83.3% of the cases, after a mean of 1.67 session of APC. Moreover, 66 patients had complications with the treatment, and rectal pain was the most referred. Conclusions Argon plasma coagulation is a well-tolerated and effective treatment to control rectal bleeding in patients who underwent radiotherapy, and the number of sessions varies from 1 to 2, according to the case.

Introduction: Chronic hemorrhagic radiation proctitis (CHRP) appears secondary to pelvic radiotherapy. Argon plasma coagulation (APC) is an effective, safe, easy-to-use, and relatively inexpensive therapy. Objective: To describe the short- and long-term therapeutic response of APC in patients with CHRP, as well as to evaluate the quality of life before and after the intervention. Material and Methods: Observational, prospective case series study of 46 patients with CHRP, treated at the National Center for Minimally Access Surgery between 2017 and 2020. Summary measures and comparison of means (paired Student's t-test) were used for baseline and final hemoglobin, as well as for the quality of life scores applied before and after the intervention. The Kaplan-Meier method was used to determine the recurrence free time. A level of significance less than 0.05 was estimated for a 95 por ciento confidence interval. Results: A mean of 3,6 ± 2,394 APC sessions was required. The mean hemoglobin increased 1,9 g / L. Short-term therapeutic response was observed in 100 % of patients, and long-term in 91,3 por ciento. The mean score for quality of life decreased by 12,065 points (p˂ 0,00). The perceived global perception increased by a mean of 7,326 points (p˂ 0,00). Conclusions: APC has a good therapeutic response in the short and long term with few sessions and a low number of complications, with an improvement in the quality of life of the patients(AU)

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

This study sought to identify the Social Representations of Obesity among 15 individuals who underwent bariatric surgery through the Roux-en-Y Gastric Bypass (RYGB) method and were subjected to Argon Plasma Coagulation (APC) due to weight relapse. Data were collected through interviews and analyzed via Descending Hierarchical Classification. Obesity was associated with physical limitations and difficulties in social relationships. Prejudice and difficulty in changing habits are associated with the choice to undergo surgical treatment and to weight relapse. The suffering that goes along with obesity and the difficulty in changing habits seem to be associated with the search for surgical help.


Este estudo procurou identificar as representações sociais da obesidade entre 15 indivíduos submetidos à cirurgia bariátrica pelo método Bypass Gástrico em Y de Roux (RYGB) e submetidos à Coagulação por Plasma de Argônio (APC) devido à recidiva de peso. Os dados foram coletados através de entrevistas e analisados por meio da Classificação Hierárquica Descendente. A obesidade foi associada a limitações físicas e dificuldades nas relações sociais. Preconceito e dificuldades na mudança de hábitos estão associados à escolha de se submeter a tratamento cirúrgico e à recidiva de peso. O sofrimento que acompanha a obesidade e a dificuldade de mudar hábitos parecem estar associados à busca de ajuda cirúrgica.


Este estudio buscó identificar las representaciones sociales de la obesidad entre 15 individuos que se sometieron a cirugía bariátrica utilizando el método de bypass gástrico Roux-en-Y (RYGB) y que se sometieron a coagulación con plasma de argón (APC) debido a una recaída en el peso. Los datos fueron recolectados a través de entrevistas y analizados utilizando la Clasificación Jerárquica Descendente. La obesidad se asoció con limitaciones físicas y dificultades en las relaciones sociales. Los prejuicios y las dificultades para cambiar los hábitos están asociados con la opción de someterse a un tratamiento quirúrgico y una recaída del peso. El sufrimiento que acompaña a la obesidad y la dificultad para cambiar los hábitos parecen estar asociados con la búsqueda de ayuda quirúrgica.

RESUMO

BACKGROUND AND AIMS: Radiotherapy may cause hemorrhagic radiation proctopathy (HRP). For conservative treatment of refractory HRP, argon plasma coagulation (APC) is the first-choice therapy. Endorectal formalin instillation (EFI), in turn, is an attractive treatment option because of its satisfactory results, great availability, and low cost. Nevertheless, comparative studies between these procedures are rather scarce. This study aims to make a prospective and randomized comparison of the outcomes in 2 HRP patient groups treated with either APC or EFI. METHODS: Twenty-seven patients (11 women), with a mean age of 67 years (range, 36-83), were randomized to receive either APC (n = 14) or EFI (n = 13). On completion of the treatment, comparisons were made in relation to the baseline for each patient and between groups for endoscopic findings according to the Vienna score and the telangiectasia distribution pattern score (TDP); the impact of radiation proctitis on patients' lives was made according to the modified radiation toxicity score (MRTS) and hemoglobin levels. Number of sessions, duration of therapy, and adverse events were also compared between groups. The endoscopic therapeutic success (ETS) was defined by the absence or only few residual telangiectasias (TDP ≤1) on conclusion. RESULTS: An ETS of 92.8% was achieved in patients treated with APC and 92.3% for those treated with EFI (P > .05); there was an MRTS improvement of 85.7% in APC patients and 69.2% in EFI patients (P > .05). Mild adverse events occurred, respectively, in 23% and 28.5% in the EFI and APC groups (P > .05). CONCLUSIONS: The study showed that APC and EFI have similar efficacy and a high safety profile for HRP treatment. (Clinical trial registration number: 3.120.353.).

RESUMO

BACKGROUND: The Argon Beam Coagulator (ABC) achieves hemostasis but has potential complications in the form of argon gas embolisms. Risk factors for embolisms have been identified and ABC manufacturers have developed guidelines for usage of the device to prevent embolism development. CASE REPORT: A 49 year-old male with history of recurrent cholangiocarcinoma status post resection presented for resection of a cutaneous biliary fistula. Shortly after initial use of the ABC, the patient underwent cardiac arrest. After resuscitation, air bubbles were observed in the left ventricle via Transesophageal Echo (TEE). CONCLUSION: Although argon embolisms have been described more commonly during laparoscopies, this patient most likely experienced an argon gas embolism during an open resection of a cutaneous biliary fistula via the biliary tract or vein with possible transpulmonary passage of the embolism. Consequently, a high degree of suspicion should be maintained for an argon gas embolism during ABC use in laparoscopic, open, and cutaneous surgeries.

Resumo Introdução: A Coagulação por Feixe de Argônio (CFA) promove hemostasia, mas pode levar a complicações na forma de embolia por gás argônio. Os fatores de risco para embolias foram identificados e os fabricantes de aparelhos de CFA desenvolveram diretrizes para o uso do dispositivo para impedir a ocorrência de embolia. Relato de caso: Paciente masculino de 49 anos com história de colangiocarcinoma recorrente pós-ressecção foi submetido à ressecção de fístula cutâneo-biliar. Logo após o início do uso do aparelho de CFA, o paciente apresentou parada cardíaca. Após o retorno da atividade cardíaca, a Eecocardiografia Transesofágica (ETE) detectou bolhas de ar no ventrículo esquerdo. Conclusões: Embora a embolia associada ao argônio seja mais frequentemente descrita durante laparoscopia, este paciente mais provavelmente apresentou embolia provocada pelo argônio durante cirurgia aberta para ressecção de fístula cutâneo-biliar, após o argônio ganhar acesso à circulação sanguínea através das vias biliares ou da veia biliar e possível passagem do êmbolo pela circulação pulmonar. Desta maneira, deve-se suspeitar de embolia por argônio, de forma judiciosa, durante o uso de CFA em procedimento cirúrgico laparoscópico, aberto ou cutâneo.

RESUMO

BACKGROUND AND AIMS: A significant number of patients regain weight after Roux-en-Y gastric bypass. Ablation with argon plasma coagulation (APC) plus endoscopic full-thickness suturing (FTS-APC) and ablation alone have been reported for treating weight regain when associated with gastrojejunostomy (GJ) dilation. However, comparative controlled data are still lacking. METHODS: This was a pilot single-center open-label randomized trial comparing the effectiveness and safety of APC alone versus FTS-APC for transoral outlet reduction. Patients with at least 20% weight regain from the nadir, and GJ ≥15 mm were considered eligible. The primary outcome was percentage total weight loss (%TWL) at 12 months. Secondary outcomes were the incidence of adverse events, amelioration of metabolic laboratory parameters, and improvement in quality of life and eating behavior. RESULTS: Forty patients meeting the eligibility criteria were enrolled from October 2017 to July 2018. Technical and clinical success rates were similar between the groups. At 12 months, the mean %TWL was 8.3% ± 5.5% in the APC alone group versus 7.5% ± 7.7% in the FTS-APC group (P = .71). The pre-revisional % solid gastric retention at 1 hour positively correlated with the probability of achieving ≥10% TWL at 12 months. Both groups experienced significant reductions in low-density lipoprotein and triglyceride levels at 12 months, and improvement in eating behavior and quality of life at 3 months. There were 2 cases of stenoses (1 from each group), which were successfully treated with endoscopic balloon dilation. CONCLUSION: APC alone is similar to FTS-APC in terms of technical and clinical outcomes within 1 year of follow-up. (Clinical trial registration number: NCT03094936.).

RESUMO

BACKGROUND: Roux-en-Y gastric bypass is one of the most widely performed bariatric surgeries. However, the relapse of obesity occurs in approximately 20% of patients and enlargement of the anastomosis is one of the factors associated with this relapse. Endoscopic treatment of the anastomosis has been proposed to assist in renewed weight loss. One endoscopic technique is the narrowing of the anastomosis argon plasma coagulation (APC). OBJECTIVE: Evaluate the effectiveness and safety of the endoscopic treatment of an enlarged anastomosis with APC. METHODS: A randomized controlled study was conducted comparing APC to exclusive multidisciplinary management after weight regain. RESULTS: Forty-two patients were divided into two groups: APC (n = 22) and control (n = 20). After 14 months of follow-up with a crossover at 6 months, significant improvement in satiety and greater weight loss were found in the APC group and after crossover. APC was associated with significant weight loss [9.73 (7.46, 12) vs. + 1.38 (- 1.39, 2.15)], a reduction in the anastomosis diameter [p < 0.001], early satiation [0.77 (0.44, 1.11) vs. - 0.59 (- 0.95, - 0.23), p < 0.001], and increased quality of life measured using the EQ5D index [p = 0.04] and EQ5D VAS scale [p = 0.04]. Considering total mean weight loss throughout the entire follow-up, weight loss was similar in both groups (13.02 kg in the APC and 11.52 kg in the control). CONCLUSION: Treatment of the gastrojejunal anastomosis with APC was effective and safe, with significant weight loss, the return of early satiation, and an improvement in quality of life.

RESUMO

BACKGROUND: The successful performance of ostomies for the treatment of different diseases has been described since 1706. We report herein the first case of successful ostomy utilizing a synthetic stoma created in a patient with peritoneal carcinomatosis. CLINICAL CASE: A 40-year-old woman presented with abdominal carcinomatosis due to psammomatous papillotubular adenocarcinoma consistent with primary ovarian carcinoma. The patient had negative estrogen and progesterone receptors and Ki-67 proliferative activity was 83%. She was initially treated with cytoreduction therapy, chemotherapy, and hyperthermic intraperitoneal chemotherapy. Because the patient presented with enteric perforations and the extensive tumor invasion and adhesions in all the intestinal segments made it impossible to create autologous decompression stomas, a synthetic stoma was constructed. CONCLUSIONS: Synthetic stomas can be a good treatment option when autologous stomas can not be created.


INTRODUCCIÓN: Desde el año 1706 se han descrito ostomías realizadas con éxito para el tratamiento de diferentes enfermedades; los autores describen el primer caso de éxito en una ostomía sintética en la carcinomatosis peritoneal. CASO CLÍNICO: Mujer de 40 años de edad con carcinomatosis abdominal por adenocarcinoma papilar tubulopapilar psamomatoso más consistente con cáncer primario de ovario, negativo a receptores de estrógenos y progesterona, con marcador Ki-67 al 83% de actividad. De modo inicial se trató con cirugía de citorreducción, quimioterapia, quimioterapia intraperitoneal hipertérmica y por último realización de estomas sintéticos debido a perforaciones entéricas e imposibilidad de realizar estomas descompresivos autólogos por la invasión tumoral extensa y adherencias de todas las asas intestinales. CONCLUSIONES: Los estomas sintéticos pueden ser una buena opción terapéutica cuando es imposible realizar estomas autólogos.
