    (2020) OLIVEIRA, Joel Fernandez de; CORDERO, Martin Andres Coronel; LIMA, Gustavo Rosa de Almeida; PAULO, Gustavo Andrade de; LIMA, Marcelo Simas de; MARTINS, Bruno da Costa; JR, Ulysses Ribeiro; MALUF-FILHO, Fauze
    INTRODUCTION: EUS-guided gastroenterostomy (EUS-GE) is a novel procedure for palliation of malignant gastric outlet obstruction (GOO). Our aim was to evaluate the outcomes of this technique in our initial experience. METHODS: Patients with GOO from our institute were included. Technical success was defined as the successful creation of a gastroenterostomy. Clinical success was defined as the ability to tolerate a soft diet after the procedure. We assessed adverse events and diet tolerance 1 month after the procedure. RESULTS: Three patients were included. Technical and clinical success was achieved in all cases. There were no adverse events and good diet tolerance was observed 1 month after the procedure in the included patients. CONCLUSION: EUS-GE is a promising treatment for patients with GOO.

    Comparison of the pull and introducer percutaneous endoscopic gastrostomy techniques in patients with head and neck cancer
    (2017) RETES, Felipe A.; KAWAGUTI, Fabio S.; LIMA, Marcelo S. de; MARTINS, Bruno da Costa; UEMURA, Ricardo S.; PAULO, Gustavo A. de; PENNACCHI, Caterina M. P.; GUSMON, Carla; RIBEIRO, Adriana V. S.; BABA, Elisa R.; GEIGER, Sebastian N.; SORBELLO, Mauricio P.; KULCSAR, Marco A.; RIBEIRO JR., Ulysses; MALUF-FILHO, Fauze
    Background and study aims: Percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients is associated with higher complication and mortality rates when compared to a general patient population. The pull technique is still the preferred technique worldwide but it has some limitations. The aim of this study is to compare the pull and introducer PEG techniques in patients with HNC. Patients and methods: This study is based on a retrospective analysis of a prospectively collected database of 309 patients with HNC who underwent PEG in the Cancer Institute of SAo Paulo. Results: The procedure was performed with the standard endoscope in 205 patients and the introducer technique was used in 137 patients. There was one procedure-related mortality. Age, sex and albumin level were similar in both groups. However in the introducer technique group, patients had a higher tumor stage, a lower Karnofsky status, and presented more frequently with tracheostomy and trismus. Overall, major, minor, immediate and late complications and 30-day mortality rates were similar but the introducer technique group presented more minor bleeding and tube dysfunctions. Conclusion: The push and introducer PEG techniques seem to be both safe and effective but present different complication profiles. The choice of PEG technique in patients with HNC should be made individually.

    Long-term results of an endoscopic screening program for superficial esophageal cancer in patients with head and neck squamous cell carcinoma
    (2022) MOURA, Renata Nobre; KUBOKI, Yeda; BABA, Elisa Ryoka; SAFATLE-RIBEIRO, Adriana; MARTINS, Bruno; PAULO, Gustavo Andrade de; TOLENTINO, Luciano Lenz; LIMA, Marcelo Simas de; KULCSAR, Marco Aurelio; SALLUM, Rubens Antonio Aissar; JR, Ulysses Ribeiro; MALUF-FILHO, Fauze
    Background and study aims Patients with head and neck squamous cell carcinoma (HNSCC) are at risk of a second primary tumor in the gastrointestinal tract, most commonly in the esophagus. Screening these patients for esophageal carcinoma may help detect asymptomatic dysplasia and early cancer, thus allowing curative treatment and more prolonged survival, but the impact of endoscopic screening remains uncertain. Here we aimed to describe the long-term results of an esophageal SCC screening program in patients with head and neck cancer in terms of prevalence, associated risk factors, and survival. Patients and methods We performed an observational study of a prospectively collected database including patients with HNSCC who had undergone high-definition endoscopy with chromoscopy between 2010 and 2018 at a Brazilian tertiary academic center. Results The study included 1,888 patients. The esophageal SCC prevalence was 7.9 %, with the majority (77.8 %) being superficial lesions. Significant risk factors for esophageal high-grade dysplasia (HGD) and invasive cancer included tumors of the oral cavity and oropharynx and the presence of low-grade dysplasia (LGD). Overall survival (OS) was significantly shorter among patients in whom esophageal cancer was diagnosed at an advanced stage (P < .001). OS did not significantly differ between patients with HGD and early esophageal cancer versus those without esophageal cancer (P = .210) Conclusions Endoscopic screening for superficial esophageal neoplasia in patients with HNSCC improves esophageal cancer detection. Screening could potentially benefit patients with primary cancer located at the oropharynx or oral cavity. In addition, the detection of esophageal LGD indicates a need for endoscopic surveillance.

    Pancreatic Metastasis from Papillary Thyroid Carcinoma: A Case Report
    (2020) MACHADO, Andressa A.; LENZ, Luciano; DOMINGUES, Regina B.; LIMA, Gustavo R. A.; JOSINO, Iatagan R.; CORDERO, Martin A. C.; V, Adriana Safatle-Ribeiro; MARTINS, Bruno C.; PENNACCHI, Caterina M. P. S.; GUSMON, Carla C.; PAULO, Gustavo A.; LIMA, Marcelo S.; BABA, Elisa R.; KAWAGUTI, Fabio S.; UEMURA, Ricardo S.; MALUF-FILHO, Fauze
    Introduction differentiated thyroid carcinoma presents with distant metastasis in 4% of cases, usually occurring in the lungs, bones and thoracic lymph nodes. Pancreatic involvement is extremely rare, with few cases reported in the literature. Case report A 47-years-old female patient presented abdominal pain. She had a history of papillary thyroid carcinoma surgically resected in 2009. After 10 years, computed tomography revealed hepatic lesions suggestive of secondary involvement and a solid mass in the pancreatic head. Endoscopic ultrasound fine-needle aspiration was performed in a heterogeneous hypoechoic mass located at pancreatic head. Cell block with immunohistochemistry was positive for thyroglobulin, suggesting papillary thyroid carcinoma metastasis. The patient still survives at present, treating metastasis with Cabozantinib. Conclusion endoscopic ultrasound fine-needle aspiration is a minimally invasive and accurate method of sampling lesions of the pancreas. In combination with clinical history and immunohistochemistry, can confirm diagnosis and define management.

    Endoscopic Injection of Mitomycin C for the Treatment of Pharyngoesophageal Stenosis Refractory to Endoscopic Treatment with Dilatation in Patients Treated for Head and Neck Cancer
    (2018) GUSMON-OLIVEIRA, Carla Cristina; KUBOKI, Yeda Mayumi; PAULO, Gustavo Andrade de; LIMA, Marcelo Simas de; UEMURA, Ricardo Sato; MARTINS, Bruno Costa; TOLENTINO, Luciano Lenz; SAFATLE-RIBEIRO, Adriana Vaz; KULCSAR, Marco Aurelio; RIBEIRO JR., Ulysses; MALUF-FILHO, Fauze
    Background. Management of pharyngoesophageal stenosis (PES) in patients after head and neck cancer (HNC) treatment remains a challenge. It is not uncommon that PES is refractory to dilation sessions. This study aimed at evaluating the efficacy of Mitomycin C (MMC) endoscopic injection for the treatment of refractory pharyngoesophageal stenosis. Patients and methods. This is a prospective study in patients with dysphagia following head and neck cancer treatment, without evidence suggestive of tumor recurrence, and refractory to endoscopic treatment. These patients were submitted to endoscopic dilation of the stenotic segment with thermoplastic bougies, followed by injection of MMC. We repeated the endoscopic sessions every three weeks. Results. From January 2015 to May 2015, we treated 13 patients with PES. Three patients were initially enrolled in the study for refractory stricture. We observed adverse events in all of them, with intense neck pain and ulcer development, justifying the interruption of the trial. Conclusion. The repeated injection in the short interval of MMC in refractory PES is not recommended, because it resulted in serious adverse events.

    II Brazilian consensus statement on endoscopic ultrasonography
    (2017) MALUF-FILHO, Fauze; OLIVEIRA, Joel Fernandez de; MENDONCA, Ernesto Quaresma; CARBONARI, Augusto; MACIENTE, Bruno Antonio; SALOMAO, Bruno Chaves; MEDRADO, Bruno Frederico; DOTTI, Carlos Marcelo; LOPES, Cesar Vivian; BRAGA, Claudia Utsch; DUTRA, Daniel Alencar M.; RETES, Felipe; NAKAO, Frank; SOUSA, Giovana Biasia de; PAULO, Gustavo Andrade de; ARDENGH, Jose Celso; SANTOS, Juliana Bonfim dos; SAMPAIO, Luciana Moura; OKAWA, Luciano; ROSSINI, Lucio; CARDOSO, Manoel Carlos de Brito; CAMUNHA, Marco Antonio Ribeiro; CLARENCIO, Marcos; SANTOS, Marcos Eduardo Lera dos; FRANCO, Matheus; SCHNEIDER, Nutianne Camargo; MASCARENHAS, Ramiro; RODA, Rodrigo; MATUGUMA, Sergio; GUARALDI, Simone; FIGUEIREDO, Viviane
    Background and Objectives: At the time of its introduction in the early 80s, endoscopic ultrasonography (EUS) was indicated for diagnostic purposes. Recently, EUS has been employed to assist or to be the main platform of complex therapeutic interventions. Methods: From a series of relevant new topics in the literature and based on the need to complement the I Brazilian consensus on EUS, twenty experienced endosonographers identified and reviewed the pertinent literature in databases. The quality of evidence, strength of recommendations, and level of consensus were graded and voted on. Results: Consensus was reached for eight relevant topics: treatment of gastric varices, staging of nonsmall cell lung cancer, biliary drainage, tissue sampling of subepithelial lesions (SELs), treatment of pancreatic fluid collections, tissue sampling of pancreatic solid lesions, celiac neurolysis, and evaluation of the incidental pancreatic cysts. Conclusions: There is a high level of evidence for staging of nonsmall cell lung cancer; biopsy of SELs as the safest method; unilateral and bilateral injection techniques are equivalent for EUS-guided celiac neurolysis, and in patients with visible ganglia, celiac ganglia neurolysis appears to lead to better results. There is a moderate level of evidence for: yield of tissue sampling of pancreatic solid lesions is not influenced by the needle shape, gauge, or employed aspiration technique; EUS-guided and percutaneous biliary drainage present similar clinical success and adverse event rates; plastic and metallic stents are equivalent in the EUS-guided treatment of pancreatic pseudocyst. There is a low level of evidence in the routine use of EUS-guided treatment of gastric varices.

    Long-term outcomes of endoscopic submucosal dissection and transanal endoscopic microsurgery for the treatment of rectal tumors
    (2021) KIMURA, Cintia Mayumi Sakurai; KAWAGUTI, Fabio Shiguehissa; NAHAS, Caio Sergio Rizkallah; MARQUES, Carlos Frederico Sparapan; SEGATELLI, Vanderlei; MARTINS, Bruno Costa; PAULO, Gustavo Andrade de; CECCONELLO, Ivan; RIBEIRO-JUNIOR, Ulysses; NAHAS, Sergio Carlos; MALUF-FILHO, Fauze
    Background and Aim Endoscopic submucosal dissection and transanal endoscopic microsurgery are good options for the treatment of rectal adenomas and early rectal carcinomas, but whether long-term outcomes of these procedures are comparable is not known. The aim of this study was to address this question. Methods A retrospective single-center study evaluating 98 consecutive procedures between June 2008 and December 2017 was performed in a tertiary cancer center. Consecutive patients who had undergone either endoscopic submucosal resection or transanal endoscopic microsurgery for rectal adenomas and early rectal carcinomas were evaluated, and long-term recurrence and complication rates were compared. Results Both groups were similar regarding sex, age, preoperative surgical risk, and en bloc resection rate (95.7% in the endoscopic and 100% in the surgical group, P = 0.81). Mean follow-up period was 37.6 months. Lesions resected endoscopically were significantly larger (68.5 mm) than those resected by transanal resection (44.5 mm), P = 0.003. Curative resections occurred in 97.2% of endoscopic resections and 85.2% of the surgical ones (P = 0.04). Comparing resections that fulfilled histologic curative criteria, there were no recurrences in the endoscopic group (out of 69 cases) and two recurrences in the transanal group (8.3% of 24 cases), P = 0.06. Late complications occurred in 12.7% of endoscopic procedures and 25.9% of surgical procedures (P = 0.13). Conclusions In our experience, endoscopic submucosal resection seems to have advantages over transanal endoscopic microsurgery, with similar en bloc resection rate and lower rate of late complications and recurrences. Multicenter randomized controlled trials are needed to support our findings.

    Tube-in-tube endoscopic vacuum therapy for the closure o upper gastrointestinal fistulas, leaks, and perforations
    (2022) LIMA, Marcelo Simas de; UEMURA, Ricardo Sato; GUSMON-OLIVEIRA, Carla Cristina; POMBO, Amanda Aquino de Miranda; MARTINS, Bruno Costa; LENZ, Luciano; KAWAGUTI, Fabio Shiguehissa; PAULO, Gustavo Andrade De; BABA, Elisa Ryoka; V, Adriana Safatle-Ribeiro; RIBEIRO, Ulysses; MONKEMULLER, Klaus; MALUF-FILHO, Fauze
    Background Although endoscopic vacuum therapy (EVT) has been successfully used to treat postoperative upper gastrointestinal (UGI) wall defects, its use demands special materials and several endoscopic treatment sessions. Herein, we propose a technical modification of EVT using a double tube (tube-in-tube drain) without polyurethane sponges for the drainage element. The tube-in-tube drainage device enables irrigation and application of suction. A flowchart for standardizing the management of postoperative UGI wall defects with this device is presented. Methods An EVT modification was made to achieve frequent fistula cleansing, with 3% hydrogen peroxide rinsing, and the application of negative pressure. A tube-in-tube drain without polyurethane sponges can be inserted like a nasogastric tube or passed through a previously positioned surgical drain. This was a retrospective two-center observational study, with data collected from 30 consecutive patients. Technical success, clinical success, adverse events, time under therapy, interval time from procedure to fistula diagnosis and treatment start, size of transmural defect, volume of cavity, number of endoscopic treatment sessions, and mortality were reviewed. Results 30 patients with UGI wall defects were treated. The technical and clinical success rates were 100% and 86.7%, respectively. Three patients (10%) had adverse events and three patients (10%) died. The median time under therapy was of 19 days (range 1-70) and the median number of endoscopic sessions was 3 (range 1-9). Conclusions This standardized approach and EVT modification using a tube-in-tube drain, with frequent fistula cleansing, were successful and safe in a wide variety of UGI wall defects.

    Results of endoscopic biliary drainage in patients with malignant hilar stricture
    (2023) MARTINS, Bruno Costa; PEREZ, Caio A.; RUAS, Jennifer N.; BENTO, Luiza H.; MENDONCA, Ernesto Q.; PAULO, Gustavo A. de; UEMURA, Ricardo S.; GEIGER, Sebastian N.; LIMA, Marcelo Simas de; JUKEMURA, Jose; JR, Ulysses Ribeiro; MALUF-FILHO, Fauze
    In Malignant Hilar Biliary Stricture (MHBS) palliative biliary drainage is a frequent strategy, improving the qual-ity of life, reducing pruritus, loss of appetite and relieving cholangitis. The endoscopic approach is an effective, although challenging procedure. This study aimed to evaluate technical and clinical success rates of biliary drain-age by ERCP. This is a retrospective study including all patients with MHBS referred to Instituto do Cancer do Hos-pital de Sao Paulo (ICESP) submitted to biliary drainage by ERCP, between January 2010 and December 2017. Multivariable logistic regression was performed to evaluate predictors of clinical failure, as total bilirubin levels, Bismuth classification, number of hepatic sectors drained and presence of cholangitis. In total, 82 patients pre-senting unresectable MHBS were included in this study. 58.5% female and 41.5% male, with a mean age of 60 +/- 13 years. Bismuth classification grades II, IIIA, IIIB and IV were noted in 23.2%, 15.9%, 14.6% and 46.3%, respectively. Technical and clinical success was achieved in 92.7% and 53.7% respectively. At multivariable logis-tic-regression analyses, Bismuth IV strictures were related to higher clinical failure rates when compared to other strictures levels, with an Odds Ratio of 5.8 (95% CI 1.28-20.88). In conclusion, endoscopic biliary drainage for malignant hilar biliary stricture had a high technical success but suboptimal clinical success rate. Proximal stric-tures (Bismuth IV) were associated with poor drainage outcomes.

    UNDERWATER ENDOSCOPIC MUCOSAL RESECTION FOR NON-PEDUNCULATED COLORECTAL LESIONS. A PROSPECTIVE SINGLE-ARM STUDY
    (2020) LENZ, Luciano; MARTINS, Bruno; KAWAGUTI, Fabio Shiguehisa; TELLIAN, Alexandre; PENNACHI, Caterina Maria Pia Simoni; SORBELLO, Mauricio; GUSMON, Carla; PAULO, Gustavo Andrade de; UEMURA, Ricardo; GEIGER, Sebastian; LIMA, Marcelo Simas de; SAFATLE-RIBEIRO, Adriana; BABA, Elisa; HASHIMOTO, Claudio Lyoiti; MALUF-FILHO, Fauze; RIBEIRO JR, Ulysses
    ABSTRACT BACKGROUND: Underwater endoscopic mucosal resection (UEMR) has emerged as a revolutionary method allowing resection of colorectal lesions without submucosal injection. Brazilian literature about this technique is sparse. OBJECTIVE: The aim of this study was evaluate the efficacy and safety of UEMR technique for removing non-pedunculated colorectal lesions in two Brazilian tertiary centers. METHODS: This prospective study was conducted between June 2016 and May 2017. Naïve and non-pedunculated lesions without signs of submucosal invasion were resected using UEMR technique. RESULTS: A total of 55 patients with 65 lesions were included. All lesions, except one, were successfully and completely removed by UEMR (success rate 98.5%). During UEMR, two cases of bleeding were observed (3.0%). One patient had abdominal pain on the day after resection without pneumoperitoneum. There was no perforation or delayed bleeding. CONCLUSION: This study supports the existing data indicating acceptable rates of technical success, and low incidence of adverse events with UEMR. The results of this Brazilian study were consistent with previous abroad studies.
