Disc resection is the first option in the management of rectal endometriosis for unifocal lesions with less than 3 centimeters of longitudinal diameter.

Rectosigmoid endometriosis is one of the most advanced forms of the disease affecting 3% to 37% of patients with endometriosis. Some patients are asymptomatic but others can develop severe symptoms such as abdominal and pelvic pain, diarrhea, constipation, and rectal bleeding. Transvaginal ultrasonography (USG-TV) with bowel preparation is the first-line investigation in patients with suspected bowel endometriosis and allows accurate determination of the presence of the disease. When endometriosis of rectosigmoid is diagnosed, the USG-TV helps the surgical team to define the appropriate therapeutic strategy, be it surgical or conservative. The surgical management of rectosigmoid endometriosis includes disc resection or segmental bowel resection. In recent years, disc resection has gained adherents; this approach allows the resection of macroscopic disease with fewer complications than segmental bowel resection. However, disc resection is only indicated when a lesion is unifocal, the size does not exceed 3 cm, and it does not involve more than 50% to 60% of circumference of the rectum or sigmoid wall. This article describes the laparoscopic disc resection surgical technique for intestinal deep endometriosis, its feasibility, and its current status.

LOGISTICS AND RESULTS OF A COLORECTAL CANCER SCREENING PROGRAM IN A MUNICIPALITY IN THE HINTERLAND OF ALAGOAS.

BACKGROUND: Colorectal cancer (CRC) has high mortality rates worldwide. In Brazil, it is the second most common cancer in both sexes. Delay in detecting premalignant lesions contributes to increased morbidity and mortality. In this scenario, the Piranhas project was created to track CRC in a low-income population in the hinterland of Alagoas. OBJECTIVE: The study aimed to establish the main strategies and verify the feasibility of implementing a CRC tracking program and demonstrate the results obtained in the CRC Prevention Campaign in Piranhas/AL. METHODS: The program took place in Piranhas, Alagoas, Brazil, through public-private partnerships. Individuals aged between 50 and 70 years of age were included for screening with a fecal occult blood test (FOBT) and colonoscopy in positive cases. Patient data were collected on standard forms. RESULTS: A total of 2152 patients, aged between 50 and 70 years, were screened, 130 of which underwent colonoscopy. Several preneoplastic lesions were detected in 58 patients. The adenoma detection rate (ADR) was 33.85%. CONCLUSION: The study proved to be effective and viable since 44.6% of the program participants, who underwent screening with FOBT, followed by colonoscopy in positive cases, had some type of preneoplastic lesion. In addition, the program generated a significant social impact on the population of Piranhas due to the opportunity to diagnose and treat CRC precursor lesions.

ANALYSIS OF THE TRACKING INITIATIVES OF COLORECTAL CANCER IN BRAZIL.

BACKGROUND: Colorectal cancer (CRC) is an important public health problem, as it represents the world's third most diagnosed neoplasm and the fourth cause of mortality. Its prevention can be divided into primary, secondary, demonstrated by tracking techniques, and tertiary, which consists of cancer diagnosis in symptomatic patients. Despite presenting a high incidence, the mortality rates decreased in the past two decades in developed countries, while the opposite happened in underdeveloped countries. That is attributed to the increase of colorectal cancer tracking programs in developed countries, which allows the precocious diagnosis and treatment of precancerous injuries and CRC. In that manner, the American Cancer Society divides the secondary tracking methods in exams based on feces samples and visual analysis of the colon and rectum, indicating its initiation starting at 45 years old in lower-risk patients. OBJECTIVE: Verify in an analytical way the actions of colorectal cancer tracking held in Brazil, as to evaluate the necessity of implementation of a national tracking program of CRC. METHODS: The methodology was based on a descriptive-quantitative secondary study that correlated the incidence of CRC, its morbidity and mortality, and the impact of the precocious tracking programs. It included activities not reported in medical literature through personal contacts with coordinators of regional programs to compare with the existent data in the literature. It was used as a variable for the tracking strategies the exams held, and their respective results. RESULTS: It described nine programs held in different regions in Brazil, using two screening methods for CRC: a noninvasive method that consists of the research of blood hidden in feces, being the majority through the FIT method, and an invasive method, having the colonoscopy as its representant. These initiatives were effective in the detection of early forms of this disease. CONCLUSION: Despite the existence of several private tracking programs and the broad divulgation of the importance of the tracking and the early diagnosis of colorectal cancer, it was demonstrated that Brazil lacks a national program that patronizes the tracking methods, which reflects in the major prevalence of late diagnosis in the population.

Implementation and results of a gastrointestinal cancer screening program in an Amazon rainforest village: A descriptive study.

Background and study aims Gastrointestinal cancer is an important cause of death worldwide. Remote populations are especially vulnerable to these conditions due to reduced access to screening and adequate treatment. In this context, the Belterra project was designed as a pilot taskforce to deliver gastrointestinal screening to an underserved Amazonian population and to spread knowledge and practice to local health workers. This study aimed to describe the implementation and present the results of the Belterra Project. Patients and methods The project took place between October 2014 and December 2017 in Belterra, Pará, Brazil. Public-private partnerships were obtained and were essential for funding. The project required complex logistic solutions to provide gastrointestinal screening to every inhabitant between 50 and 70 years of age, including medical equipment and personal transportation to a remote area. Subjects were asked about their medical history, and received a physical examination, endoscopic examinations, and stool tests. Results Over the course of 19 expeditions, we screened 2,022 inhabitants of Belterra, aged 50 to 70 years. Five colorectal and six gastric adenocarcinomas were diagnosed, as were several lower-stage lesions. Overall, 26 % of the participants undergoing colonoscopy showed some type of colonic lesion. Conclusions Notwithstanding the geographical, cultural, and financial barriers, this study suggests that the implementation of a gastrointestinal cancer screening program for remote Brazilian populations is feasible, reaching high adherence. Although logistics is very demanding, such campaigns may be a good strategy to provide mass gastrointestinal cancer screening for underserved populations.

SURGICAL TECHNIQUES FOR THE TREATMENT OF RECTAL ENDOMETRIOSIS: A SYSTEMATIC REVIEW OF RANDOMIZED CONTROLLED TRIALS AND OBSERVATIONAL STUDIES.

BACKGROUND: Endometriosis is a common disease in reproductive-age women and it is estimated to occur in up to 50% of those with infertility. Intestinal involvement is reported in up to a third of the cases. This condition is related to chronic pain and loss of quality of life, resulting in emotional, social and economic costs. Treatment consists of hormonal block and surgical resection, with variable side effects and efficacy. The best choice for surgical treatment for rectal endometriosis is a matter of discussion regarding the indication and the best technique to be employed. OBJECTIVE: To summarize data on indications, results and complications of surgical techniques for the treatment of rectal endometriosis. METHODS: This comprehensive systematic review is a compilation of the available literature and discussion, carried out by a team with experience in the surgical treatment of intestinal endometriosis. Data regarding indications, results and complications of conservative and radical techniques for the surgical treatment of rectal endometriosis was carefully reviewed. Searches of PubMed, EMBASE, and CENTRAL up to May 2021 were performed to identify randomized controlled trials (RCTs) and observational studies that compared at least two of the three surgical techniques of interest (i.e., shaving, discoid resection, segmental resection). RESULTS: One RCT and nine case series studies with a total of 3,327 patients met the eligibility criteria. Participants ages ranged from a mean of 30.0 to 37.9 years old. Mean follow-up ranged from 1.2 to 42.76 months. With regards the methodological quality, overall the included studies presented a low risk of bias in the majority of the domains. Surgical treatment of rectal endometriosis is indicated for patients with obstructive symptoms and those with pain scores above 7/10. Patients with disease involving beyond muscularis propria of the rectum, documented in magnetic resonance imaging or transvaginal pelvic ultrasound with intestinal preparation, are candidates for discoid or segmental resection. The presence of multifocal disease, extension greater than 3 cm and infiltration greater than 50% of the loop circumference favor the radical technique. The distance from the lesion to the anal verge, age, symptoms and reproductive desire are other factors that influence the choice of the technique to be employed. The risk of complications and unfavorable functional results seems to be directly related to the complexity of the procedure. CONCLUSION: The choice of surgical technique performed for the treatment of rectal endometriosis is a matter of discussion and depends not only on the preoperative staging, but also on the patient's expectations, risks and potential complications, recurrence rates and the expertise of the multidisciplinary team.

Transvaginal ultrasound for diagnosis of deeply infiltrating endometriosis.

Deeply infiltrating endometriosis is the clinical form of the disease that is generally associated with conditions of more intense pain and may require more complex surgical management, consequently resulting in greater risks to the patient. In recent years, various investigators have confirmed the usefulness of methods such as magnetic resonance imaging (MRI), transrectal ultrasound and transvaginal ultrasound (TVUS) for the diagnosis of deep endometriotic lesions. The objectives of the present study are to describe the method used to perform TVUS for the detection of deeply infiltrating endometriosis, and to discuss the clinical benefits that the data obtained may offer clinicians providing care for patients suspected of having this type of endometriosis.

ENDOSCOPIC BAND LIGATION FOR THE TREATMENT OF HEMORRHOIDAL DISEASE.

BACKGROUND: There are several therapeutic options for symptomatic hemorrhoids, from hygienic and dietary measures to conventional surgery. The best technique adopted for alternative and non-surgical treatment for intermediate grade (II and III) hemorrhoidal disease is rubber band ligation. More recently, the technique has been used with the aid of a gastroscope and a kit of elastic rubber bands for esophageal varices. This technique was called Endoscopic Rubber Band Ligation of hemorrhoids (ERBL). OBJECTIVE: The objective is Compare the results and the incidence of the immediate and late complications in patients undergoing ERBL. The satisfaction with the treatment of patients undergoing different number of rubber band ligatures were also analyzed. METHODS: This is a cohort study included patients undergoing ERBL from 2007 to 2014 at the hospital. The incidence of early and late complications and the satisfaction with the treatment of patients undergoing until two ligatures and patients undergoing three or more ligatures in the same procedure were compared. RESULTS: The study included 116 patients. The most frequently reported symptom was anal bleeding (n=72; 62.1%). The number of rubber band ligatures performed during the ERBL procedure varied from one to six; 84 (72,4%) patients had three or more rubber band ligatures performed during the procedure. No significant associations were observed between the incidence of early or late complications and satisfaction with ERBL among the group subjected until two rubber band ligatures or three or more rubber band ligatures. CONCLUSION: The endoscopic elastic ligation method proved to be a feasible, safe and efficient for the treatment of symptomatic hemorrhoidal disease grades II and III. The technique had moderate rates of immediate and late complications, but most of the complications are considered of low magnitude, easily resolved and without clinical repercussions, no matter how much ligations were performed in the same procedure.

Chronic colitis associated with HIV infection can be related to intraepithelial infiltration of the colon by CD8+ T lymphocytes.

Gastrointestinal complications in AIDS patients with diarrhoea are common clinical manifestations, frequently diagnosed by colonoscopy as non-specific colitis. We retrospectively study colon biopsies diagnosed as chronic colitis associated with HIV (CCH). Biopsies were sorted as patients with AIDS (serum CD4 <200 cell/mm3) but without any clear infectious process (n = 12) and patients without HIV infection (n = 24). There are low numbers of CD4+ T lymphocytes in lamina propria of AIDS patients, but CD8+ T populations in this area appear to be similar in all studied groups, regardless of HIV infection or laboratory evidence of a specific agent. We found the clear evidence of CD8+ T cells infiltration in colonic mucosa in HIV patients with microscopic colitis. An imbalance of lymphocyte subpopulations in the colon, both in the lamina propria and epithelium, could result in an intraepithelial CD8 infiltration, involved in the pathogenesis of CCH in AIDS patients.

RESUMO Contexto: O câncer colorretal (CCR) é um importante problema de saúde pública, uma vez que representa a terceira neoplasia mais diagnosticada no mundo e a quarta causa de mortalidade. Sua prevenção pode ser dividida em primária, secundária, demonstrada pelas técnicas de rastreamento e terciária, que consiste no diagnóstico de câncer em pacientes sintomáticos. Apesar de apresentar uma alta incidência, as taxas de mortalidade diminuíram nas últimas duas décadas nos países desenvolvidos, enquanto o contrário ocorreu em países subdesenvolvidos, o que atribui-se a elevação dos programas de rastreamento colorretal nesses países, de modo que permite o diagnóstico precoce e o tratamento de lesões pré-cancerosas e do CCR. Desse modo, a American Cancer Society divide os métodos de rastreio secundário em testes baseados em amostras de fezes e exames visuais do cólon e reto, indicando-se seu início a partir dos 45 anos de idade, em pacientes de baixo risco. Objetivo: Verificar de forma analítica as ações de rastreamento do câncer colorretal realizadas no Brasil, de modo a avaliar a necessidade da implementação de um programa nacional de rastreamento do CCR. Métodos: A metodologia baseou-se em um estudo secundário quantitativo descritivo que correlacionou a incidência do CCR e sua morbimortalidade e o impacto dos programas de rastreamento precoce. Foram incluídas atividades não relatadas na literatura médica através de contatos pessoais com coordenadores de programas regionais, de modo a comparar com os dados existentes na literatura. Utilizou-se como variáveis as estratégias de triagem, os exames realizados e seus respectivos resultados. Resultados: Foram descritos nove programas realizados em diversas regiões do Brasil utilizando dois métodos de rastreio para o CCR, um não invasivo que consiste na pesquisa de sangue oculto nas fezes, sendo a maioria pelo método FIT; e outro invasivo, tendo a colonoscopia como representante. Essas iniciativas foram efetivas na detecção de formas precoces desta doença. Conclusão: Apesar da existência de diversos programas de rastreamento de início privativo e a ampla divulgação da importância do rastreamento e diagnóstico precoce do CCR, foi demonstrado que o Brasil carece de um programa nacional que padronize as formas de rastreio, o que reflete na maior prevalência de diagnósticos tardios na população.

Cytomegaloviral colitis in HIV positive patients: endoscopic findings.

BACKGROUND: Diarrhea in seropositive human immunodeficiency virus patients is one of the most important and disabling symptoms, and often decreases their quality of life. Cytomegalovirus colitis is among the principal causes of this symptom and colonoscopy is the gold standard examination to diagnose it. AIM: To define the main endoscopic findings in seropositive human immunodeficiency virus patients with cytomegalovirus colitis. METHODS: Two hundred and forty-three colonoscopies were performed in 200 seropositive human immunodeficiency virus patients with diarrhea associated or not to abdominal pain or gastrointestinal bleeding, over 10-year period, whom 51 patients were diagnosed with cytomegalovirus colitis. Full length colonoscopy with ileum intubation was always tried and multiple biopsies of all segments examined, including endoscopically normal segments, were attempted. All diagnoses were confirmed by histologic and immunohistochemical studies. RESULTS: Total colonoscopy was possible in 98.03% and ileum intubation in 88.23% of these cytomegalovirus colitis patients. At colonoscopy, a heterogeneous ulcerative pattern was presented in 72.54%, an inflammatory process of the mucosa in 21.56% and 5.88% of the patients mucosa was endoscopically normal. CONCLUSION: Full length colonoscopy with ileum intubation and multiples biopsies of all segments, even when they are endoscopically normal, have always to be attempted in cases of seropositive human immunodeficiency virus patient with diarrhea.

[I Brazilian consensus of endoscopic ultrasonography]. / I Consenso Brasileiro de Ecoendoscopia.

BACKGROUND: In the last 20 years, several papers have focused on demonstrating the impact of endoscopic ultrasonography findings on the management of different clinical scenarios in digestive disease. This fact is an indirect evidence of the difficulty of popularization of the method. On other hand, the limited availability of endoscopic ultrasonography in Brazil is a direct evidence of this limitation. This was the rationale for the organization of a consensus meeting on endoscopic ultrasonography. It was aimed to identify the best evidence that support the use of endoscopic ultrasonography in gastroenterology. METHODS: A panel of experts on endoscopic ultrasonography was selected based on the files of the Gastroenterology and Endoscopy Societies and on the registries of endoscope manufacturers. Two members of the meeting selected the relevant topics that were transformed into questions. The topics and the questions were debated among the experts five months before the consensus meeting. The experts were asked to perform systematic reviews in order to answer the questions so it could be possible to grade the answers based on the strength of the evidence. During the two days of the meeting the answers were presented, debated and voted. Consensus was reached when a minimum of 70% of the voters were in agreement. The final consensus report was submitted to the experts' evaluation and approval. RESULTS: Seventy nine questions were debated by the experts at the pre-Consensus meeting. As the result of this debate 85 questions came out and were assigned to the members of the panel. During the Consensus meeting 22 experts debated and voted 85 answers. Consensus was reached for several clinical scenarios for which the impact of endoscopic ultrasonography findings were supported by level 1 evidences: differential diagnosis of subepithelial lesions and thickening of gastric folds, staging and diagnosis of unresectable esophageal cancer, indirect signs of peritoneal involvement of gastric cancer, MALT gastric lymphoma and rectal cancer staging, diagnosis of common bile duct and gallbladder stones, diagnosis of chronic pancreatitis and differential diagnosis of a solid mass in chronic pancreatitis, differential diagnosis of the pancreatic cyst, prediction of the results of the endoscopic treatment of esophageal varices and diagnosis and staging of non-small cell lung cancer. CONCLUSIONS: There are the highest levels of evidences that support the indication of endoscopic ultrasonography for several digestive diseases and even for non-small cell lung cancer.

Técnicas cirúrgicas para o tratamento da endometriose do reto: revisão sistemática de ensaios clínicos randomizados e estudos observacionais / Surgical techniques for the treatment of rectal endometriosis: a systematic review of randomized controlled trials and observational studies

RESUMO CONTEXTO: A endometriose é uma doença prevalente em mulheres em idade reprodutiva e estimada em até 50% daquelas com infertilidade. O acometimento intestinal é reportado em até um terço dos casos. A doença é relacionada a dor crônica e perda de qualidade de vida, implicando em custos emocionais, sociais e econômicos. O tratamento consiste em bloqueio hormonal e ressecção cirúrgica, com efeitos colaterais e eficácia variáveis. A abordagem cirúrgica da endometriose do reto, conservadora ou radical, é motivo de discussão no que tange a indicação e a melhor técnica a ser empregada. OBJETIVO: Resumir os dados da literatura sobre as indicações, resultados e complicações das técnicas cirúrgicas para o tratamento da endometriose do reto. MÉTODOS: Esta revisão sistemática abrangente é uma seleção de estudos da literatura e sua discussão, realizada por equipe com experiência no tratamento cirúrgico da endometriose intestinal, sobre as indicações, resultados e complicações das técnicas conservadoras, ressecção superficial e discoide, e radical para o tratamento cirúrgico da endometriose do reto. Foi realizada uma estratégia de busca nas bases de dados PubMed, EMBASE, e CENTRAL até maio de 2021 para identificar ensaios clínicos randomizados e estudos observacionais que compararam pelo menos duas das três técnicas cirúrgicas de interesse (i.e., shaving, ressecção discóide, ressecção segmental). RESULTADOS: Um ensaio clínico randomizado e nove séries de casos, com um total de 3.327 pacientes, preencheram os critérios de elegibilidade da revisão. A idade dos participantes variou de uma média de 30,0 a 37,9 anos. O seguimento médio variou de 1,2 a 42,76 meses. Referente à qualidade metodológica, no geral os estudos incluídos apresentaram baixo risco de viés na maioria dos domínios avaliados. O tratamento cirúrgico das pacientes com endometriose do reto está indicado para as pacientes com sintomas obstrutivos e naquelas com escores de dor acima de 7/10. As pacientes com doença além da camada muscular própria do reto, documentada por meio de ressonância magnética ou ultrassonografia pélvica transvaginal com preparo intestinal, são candidatas a ressecção discoide ou segmentar. A presença de doença multifocal, extensão maior de 3 cm e infiltração maior 50% da circunferência da alça favorecem a técnica radical. A altura da lesão em relação a borda anal, idade, sintomatologia e desejo reprodutivo são outros fatores que podem influenciar na escolha da técnica a ser empregada. O risco de complicações e resultados funcionais desfavoráveis parecem estar relacionados diretamente a complexidade do procedimento. CONCLUSÃO: A escolha da técnica cirúrgica, conservadora ou radical, realizada pela via laparoscópica, para o tratamento da endometriose do reto é motivo de discussão e depende não somente do estadiamento pré-operatório, mas também das expectativas da paciente, dos riscos e potenciais complicações, das taxas de recorrência e da expertise da equipe multidisciplinar.
