RESUMO
OBJECTIVE: To evaluate the adoption and clinical impact of endoscopic resection (ER) in early esophageal cancer. BACKGROUND: Staging for early esophageal cancer is largely inaccurate. Assessment of the impact of ER on staging accuracy is unknown, as is the implementation of ER. METHODS: We retrospectively reviewed 2608 patients captured in the Society of Thoracic Surgeons General Thoracic Surgery Database between 2015 and 2020. Patients with clinical T1 and T2 esophageal cancer without nodal involvement (N0) who were treated with upfront esophagectomy were included. Staging accuracy was assessed by clinical-pathologic concordance among patients staged with and without ER. We also sought to measure adherence to National Comprehensive Cancer Network staging guidelines for esophageal cancer staging, specifically the implementation of ER. RESULTS: For early esophageal cancer, computed tomography/positron emission tomography/endoscopic ultrasound (CT/PET/EUS) accurately predicts the pathologic tumor (T) stage 58.5% of the time. The addition of ER to staging was related to a decrease in upstaging from 17.6% to 10.8% ( P =0.01). Adherence to staging guidelines with CT/PET/EUS improved from 58.2% between 2012 and 2014 to 77.9% between 2015 and 2020. However, when ER was added as a staging criterion, adherence decreased to 23.3%. Increased volume of esophagectomies within an institution was associated with increased staging adherence with ER ( P =0.008). CONCLUSIONS: The use of CT/PET/EUS for the staging of early esophageal cancer is accurate in only 56.3% of patients. ER may increase staging accuracy as it is related to a decrease in upstaging. ER is poorly utilized in staging of early esophageal cancer. Barriers to the implementation of ER as a staging modality should be identified and corrected.

Context: Patients with pancreatic cancer (PC) at a late stage often suffer from severe abdominal pain due to the invasion of celiac plexus, and the analgesics they receive often have intolerable side effects. Endoscopic, ultrasound-guided, celiac plexus neurolysis (EUS-guided CPN) can have a good therapeutic effect. Objective: The study intended to evaluate the ability of two nursing cooperation patterns to reduce patients' pain, decrease operation times, increase operational efficiency, and increase nurses' satisfaction, for patients with advanced PC and abdominal pain who received EUS-guided CPN. Design: The research team designed a retrospective controlled study. Setting: The study took place at the Shenzhen People's Hospital of the Second Clinical Medical College of Jinan University in Shenzhen, China, and at the Changhai Hospital of the Second Military Medical University in Shanghai, China. Participants: Participants were 40 patients with advanced PC who received EUS-guided CPN at one of the two hospitals between January 2019 and January 2020. Intervention: Twenty participants at Changhai Hospital received the traditional nursing cooperation pattern and became the control group, and 20 participants at the Shenzhen People's Hospital received the new nursing cooperation pattern and became the intervention group. Outcome Measures: The study measured clinical data, nursing measures, diagnostic significance, and key points for the two patterns as well as compared the effects of the new nursing cooperation method to that of traditional nursing. If the measurement data met the requirements for normality, the team used the two independent sample t-test for the intergroup comparisons. If normality wasn't satisfied, the team used medians and interquartile ranges (IQRs) for expression and the rank sum test for the intergroup comparisons. Counting data were expressed using the constituent ratio, and team used the chi-square test for comparisons between groups. P < .05 was considered to be statistically significant. Results: The operations were successful, and no complications occurred. No significant difference existed in the pain scores between the control group and the intervention group (P > .05), while a significant difference occurred in the nurses' operation times and satisfaction. Not only were the scores for operation times for the control group (97) and the intervention group (59) significantly different, but also the nurses' satisfaction was significantly higher for the intervention group postintervention, at 83.35 ± 5.25, than for the control group, at 62.25 ± 8.18 (P < .001). Such a new nursing cooperation method could assist in patient's rehabilitation and increase nurses' satisfaction. Conclusions: The new nursing cooperation method for patients with advanced PC and abdominal pain undergoing EUS-guided CPN can reduce operation time and improve nurses' satisfaction.

ABSTRACT: The etiology of distal common bile duct (CBD) dilatation is complex. Linear-array endoscopic ultrasonography (EUS) can not only visualize the distal and surrounding structures of the bile duct closely but also obtain pathological specimens by fine-needle aspiration, which provides an important basis for the diagnosis and differential diagnosis. The purpose of this study was to evaluate the diagnostic value of linear-array EUS in the etiology of distal CBD dilatation. Patients with distal CBD dilatation underwent linear-array EUS in the endoscopic center of The Second Affiliated Hospital of Soochow University and Traditional Chinese Medicine Hospital of Kunshan were collected from January 2015 to June 2019. The pathology results after surgery, endoscopic pathology, computed tomography (CT), and magnetic resonance imaging (MRI) results were retrospectively analyzed. The diagnostic accuracy of linear-array EUS and CT or MRI was compared. For the diagnosis of choledocholithiasis, the diagnostic accuracy of linear-array EUS was 97.5%, which was significantly higher than that of MRI (86.36%) and CT (89.74) (P < 0.001 and 0.006, respectively). The diagnostic accuracy of linear-array EUS for periampullary tumors was 93.75%, which was higher than MRI and CT with an accuracy of 82.73% and 80.34% (P = 0.004 and 0.001, respectively). Linear EUS was effective for the etiological diagnosis of distal CBD dilatation.

BACKGROUND AND STUDY AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for the treatment of biliary obstruction of any etiology. However, cannulation failure of the common bile duct (CBD) by ERCP occurs in 5-10%. Alternatives after a failed ERCP are re-ERCP by an expert endoscopist, percutaneous transhepatic cholangio drainage (PTCD), (balloon) enteroscopy-assisted ERCP, or surgery. Endoscopic ultrasonography-guided drainage of the bile ducts (EUS-BD) is becoming the standard of care in tertiary referral centers for cases of failed ERCP in patients with malignant obstruction of the CBD. In expert hands, EUS-guided biliary drainage has excellent technical/clinical success rates and lower complication rates compared to PTCD. Despite the successful performance of EUS-BD in malignant cases, its use in benign cases is limited. The aim of this study (design, systematic prospective clinical observational study on quality assurance in daily clinical practice) was to evaluate the efficacy and safety of EUS-BD in benign indications. PATIENTS AND METHODS: Patients with cholestasis and failed ERCP were recruited from a prospective EUS-BD registry (2004-2020). One hundred and three patients with EUS-BD and benign cholestasis were extracted from the registry (nTotal = 474). Indications of EUS-BDs included surgically altered anatomy (n = 65), atypical bile duct percutaneous transhepatic cholangio orifice at the duodenal junction from the longitudinal to the horizontal segment (n = 1), papilla of Vater not reached due to the gastric outlet/duodenal stenoses (n = 6), papilla that cannot be catheterized (n = 24), and proximal bile duct stenosis (n = 7). The primary endpoint was technical and clinical success. Secondary endpoints were procedure-related complications during the hospital stay. RESULTS: 103 patients with EUS-BD and benign cholestasis were extracted from the registry (nTotal=474). Different transluminal access routes were used to reach the bile ducts: transgastric (n = 72/103); -duodenal (n = 16/103); -jejunal (n = 14/103); combined -duodenal and -gastric (n = 1/103). The technical success rate was 96 % (n = 99) for cholangiography. Drainage was not required in 2 patients; balloon dilatation including stone extraction was sufficient in 17 cases (16.5 %; no additional or prophylactic insertion of a drain). Transluminal drainage was achieved in n = 68/103 (66 %; even higher in patients with drain indication only) by placement of a plastic stent (n = 29), conventional biliary metal stents (n = 24), HotAXIOS stents (n = 5; Boston Scientific, Ratingen, Germany), Hanaro stents (n = 6; Olympus, Hamburg, Germany), HotAXIOS stents and plastic stents (n = 1), HotAXIOS stents and metal stents (n = 1) and metal stents and plastic stents (n = 2). Techniques for stone extraction alone (nSuccessful=17) or stent insertion (nTotal = 85; nSuccessful=85 - rate, 100 %) and final EUS-BD access pathway included: Rendezvous technique (n = 14/85; 16.5 %), antegrade internal drainage (n = 20/85; 23.5 %), choledochointestinostomy (n = 7/85; 8.2 %), antegrade internal and hepaticointestinostomy (n = 22/85; 25.9 %), hepaticointestinostomy (n = 21/85; 24.7 %), choledochointestinostomy and hepaticointestinostomy (n = 1/85; 1.2 %).The complication rate was 25 % (n = 26) - the spectrum comprised stent dislocation (n = 11), perforation (n = 1), pain (n = 2), hemorrhage (n = 6), biliary ascites/leakage (n = 3) and bilioma/liver abscess (n = 3; major complication rate, n = 12/68 - 17.6 %). Re-interventions were required in 19 patients (24 interventions in total). DISCUSSION: EUS-BD can be considered an elegant and safe alternative to PTCD or reoperation for failed ERCP to achieve the necessary drainage of the biliary system even in underlying benign diseases. An interventional EUS-based internal procedure can resolve cholestasis, avoid PTCD or reoperation, and thus improve quality of life. Due to the often complex (pathological and/or postoperative) anatomy, EUS-BD should only be performed in centers with interventional endoscopy/EUS experience including adequate abdominal surgery and interventional radiology expertise in the background. This enables adequately adapted therapeutic management in the event of challenging complications. It seems appropriate to conduct further studies with larger numbers of cases to systematize the approach and peri-interventional management and to successively develop specific equipment.

BACKGROUND AND AIMS: Image-guided radiation therapy (IGRT) often relies on EUS-guided fiducial markers. Previously used manually backloaded fiducial needles have multiple potential limitations including safety and efficiency concerns. Our aim was to evaluate the efficacy, feasibility, and safety of EUS-guided placement of gold fiducials using a novel preloaded 22-gauge needle compared with a traditional, backloaded 19-gauge needle. METHODS: This was a single-center comparative cohort study. Patients with pancreatic and hepatobiliary malignancy who underwent EUS-guided fiducial placement (EUS-FP) between October 2014 and February 2018 were included. The main outcome was the technical success of fiducial placement. Secondary outcomes were mean procedure time, fiducial visibility during IGRT, technical success of IGRT delivery, and adverse events. RESULTS: One hundred fourteen patients underwent EUS-FP during the study period. Of these, 111 patients had successful placement of a minimum of 2 fiducials. Fifty-six patients underwent placement using a backloaded 19-gauge needle and 58 patients underwent placement using a 22-gauge preloaded needle. The mean number of fiducials placed successfully at the target site was significantly higher in the 22-gauge group compared with the 19-gauge group (3.53 ± .96 vs 3.11 ± .61, respectively; P = .006). In the 22-gauge group, the clinical goal of placing 4 fiducials was achieved in 78%, compared with 23% in the 19-gauge group (P < .001). In univariate analyses, gender, age, procedure time, tumor size, and location did not influence the number of successfully placed fiducials. Technical success of IGRT with fiducial tracking was high in both the 19-gauge (51/56, 91%) and the 22-gauge group (47/58, 81%; P = .12). CONCLUSIONS: EUS-FP using a preloaded 22-gauge needle is feasible, effective, and safe and allows for a higher number of fiducials placed when compared with the traditional backloaded 19-gauge needle.

PURPOSE: The aim of this study was to assess the post biopsy infection rate, feasibility and prostate cancer (PCa) detection rate (CDR) by performing transperineal MRI-TRUS fusion biopsy of the prostate (TPBx) under local anesthesia (LA) without antibiotic prophylaxis (AP). METHODS: We prospectively screened 766 men with suspicious lesions on mpMRI, an elevated PSA level or a suspect digital examination undergoing MRI-TRUS-TPBx in LA, from May 2019 to July 2020. Patients with the need for antibiotic prophylaxis or without a PI-RADS target lesion were excluded from final analyses. We reported CDR, perioperative pain (0-10) and postoperative complications. PCa with an ISUP grade ≥ 2 was classified as clinically significant PCa (csPCa). RESULTS: We included 621 patients with a median age of 68 years (IQR 62-74), a PSA of 6.43 ng/mL (IQR 4.72-9.91) and a prostate volume of 45 cc (IQR 32-64). In median, 4 targeted (TB) (IQR 3-4) and 6 (IQR 5-7) systematic biopsies (SB) detected in combination overall 416 (67%) PCa and 324 (52%) csPCa. Overall CDR of TB for PI-RADS 3, 4 and 5 was 26%, 65% and 84%, respectively. Patients reported a median perioperative pain level of 2 (IQR 1-3). Four patients (0.6%) developed a post biopsy infection, one experienced urosepsis. CONCLUSION: Our results demonstrate that transperineal MRI-TRUS fusion-guided prostate biopsy under LA without AP is feasible, safe and well tolerated.

Double-contrast barium enema (DCBE), transrectal endoscopic ultrasonography (REU), multidetector computerized tomography enema (MDCT-e), and computed tomography colonoscopy (CTC) have been successfully used for the diagnosis of bowel endometriosis. DCBE provides a complete overview of the entire colon and allows detecting cecal nodules. The accuracy of DCBE is operator dependent and, thus, it may have low specificity. It does not allow identifying the cause of the mass effect. DCBE requires the administration of barium and exposure to radiation. REU precisely estimates the distance between the rectosigmoid nodule and the anal verge. However, it allows investigating only the distal part of rectosigmoid, it misses anterior pelvic lesions, and it has poor sensitivity for the diagnosis of endometriomas. MDCT-e is accurate and reproducible in diagnosing intestinal endometriosis and in assessing its characteristics: the largest diameter of the nodule, the distance between the distal part of the nodule and the anal verge, and depth of infiltration of endometriosis in the intestinal wall. MDCT-e requires the administration of iodinated contrast medium (CM) and the exposure to radiations. CTC has good performance in the diagnosis of rectosigmoid endometriosis. It allows estimating the degree of intestinal stenosis CTC, and the distance between the intestinal endometriotic nodule and the anal verge. It requires exposure to radiations, and it may require the administration of an iodinated CM.

Current conventional endoscopes have restricted the accuracy of treatment delivery and monitoring. Over the past decade, there have been major developments in nanotechnology and light triggered therapy, potentially allowing a better detection of challenging lesions and targeted treatment of malignancies in the gastrointestinal tract. Theranostics is a developing form of personalized medicine because it combines diagnosis and targeted treatment delivered in one step using advances in nanotechnology. This review describes the light-triggered therapies (including photodynamic, photothermal, and photoimmunotherapies), nanotechnological advances with nanopowder, nanostent, nanogels, and nanoparticles, enhancements brought to endoscopic ultrasound, in addition to experimental endoscopic techniques, combining both enhanced diagnoses and therapies, including a developed prototype of a "smart" multifunctional endoscope for localized colorectal cancer, near-infrared laser endoscope targeting the gastrointestinal stromal tumors, the concept of endocapsule for obscure gastrointestinal bleed, and a proof-of-concept therapeutic capsule using ultrasound-mediated targeted drug delivery. Hence, the following term has been proposed encompassing these technologies: "Theranostic gastrointestinal endoscopy." Future efforts for integration of these technologies into clinical practice would be directed toward translational and clinical trials translating into a more personalized and interdisciplinary diagnosis and treatment, shorter procedural time, higher precision, higher cost-effectiveness, and less need for repetitive procedures.

INTRODUCTION: Pediatric chronic pancreatitis is increasingly diagnosed. Endoscopic methods [endoscopic ultrasound (EUS), endoscopic retrograde cholangiopancreatography (ERCP)] are useful tools to diagnose and manage chronic pancreatitis. Pediatric knowledge and use of these modalities is limited and warrants dissemination. METHODS: Literature review of publications relating to use of ERCP and EUS for diagnosis and/or management of chronic pancreatitis with special attention to studies involving 0--18 years old subjects was conducted with summaries generated. Recommendations were developed and voted upon by authors. RESULTS: Both EUS and ERCP can be used even in small children to assist in diagnosis of chronic pancreatitis in cases where cross-sectional imaging is not sufficient to diagnose or characterize the disease. Children under 15âkg for EUS and 10âkg for ERCP can be technically challenging. These procedures should be done optimally by appropriately trained endoscopists and adult gastroenterology providers with appropriate experience treating children. EUS and ERCP-related risks both include perforation, bleeding and pancreatitis. EUS is the preferred diagnostic modality over ERCP because of lower complication rates overall. Both modalities can be used for management of chronic pancreatitis -related fluid collections. ERCP has successfully been used to manage pancreatic duct stones. CONCLUSION: EUS and ERCP can be safely used to diagnose chronic pancreatitis in pediatric patients and assist in management of chronic pancreatitis-related complications. Procedure-related risks are similar to those seen in adults, with EUS having a safer risk profile overall. The recent increase in pediatric-trained specialists will improve access of these modalities for children.

OBJECTIVES: To evaluate the effect of intensified treatment parameters on safety, functional outcomes, and PSA after MR-Guided Transurethral Ultrasound Ablation (TULSA) of prostatic tissue. PATIENTS AND METHODS: Baseline and 6-month follow-up data were collected for a single-center cohort of the multicenter Phase I (n = 14/30 at 3 sites) and Pivotal (n = 15/115 at 13 sites) trials of TULSA in men with localized prostate cancer. The Pivotal study used intensified treatment parameters (increased temperature and spatial extent of ablation coverage). The reporting site recruited the most patients to both trials, minimizing the influence of physician experience on this comparison of adverse events, urinary symptoms, continence, and erectile function between subgroups of both studies. RESULTS: For Phase I and TACT patients, median age was 71.0 and 67.0 years, prostate volume 41.0 and 44.5 ml, and PSA 6.7 and 6.7 ng/ml, respectively. All 14 Phase I patients had low-risk prostate cancer, whereas 7 of 15 TACT patients had intermediate-risk disease. Baseline IIEF, IPSS, quality of life, and pad use were similar between groups. Pad use at 1 month and quality of life at 3 months favored Phase I patients. At 6 months, there were no significant differences in functional outcomes or adverse events. CONCLUSION: TULSA demonstrated acceptable clinical safety in Phase I trial. Intensified treatment parameters in the TACT Pivotal trial increased ablation coverage from 90 to 98% of the prostate without affecting 6-month adverse events or functional outcomes. Long-term follow-up and 12-month biopsies are needed to evaluate oncological safety.

Individuals at high risk for pancreatic cancer are recommended surveillance and healthy lifestyle behaviours and patient experience with recommendations are understudied. To describe engagement and experience with surveillance, tobacco and alcohol use, health beliefs and motivation (Champion Health Belief Measure) and the relationship with personal, psychosocial (Impact of Event Scale), and familial characteristics. Interest in integrative therapies (complementary therapies) are described. A multi-site cross-sectional survey including individuals at high risk for pancreatic cancer with no diagnosis of pancreatic cancer who have been evaluated at a comprehensive cancer center. Descriptive statistics and Wilcoxon rank sum test and Fisher's exact test were used to assess univariate associations. Of the 132 respondents (72% response rate), 92 (70%) reported undergoing surveillance which was associated with older age (p = 0.001). Of which, 36% and 51% report that magnetic resonance imaging (MRI) or endoscopic ultrasound (EUS), respectively, were uncomfortable; 22% and 30% dread the next MRI or EUS, respectively. Of those who reported alcohol consumption (n = 88); 15% consumed 1 or more drinks daily and no alcohol consumption was associated with higher Impact of Event scale scores (p = 0.024). A total of six participants were currently smoking every day or some days. Participants reported high motivation to engage in heathy behaviours and 92% were interested in integrative therapies. In these select participants, most were engaging in pancreatic cancer surveillance, alcohol intake was moderate, and tobacco intake was minimal. Modifiable factors, such as experience and comfort with surveillance could be addressed. The sample is motivated to engage in behavioural health intervention.

Preoperative clinical staging is critical to select those patients whose disease is localized and may benefit from surgery with curative intent. Ideally, such staging should predict tumor invasion, lymphatic involvement and distant metastases. With the cTNM, we are able to select patients who could benefit from endoscopic resection, radical surgery or less radical treatment in patients with distant metastasis. The initial diagnosis of adenocarcinomas of the esophagogastric junction requires endoscopy with biopsies. For clinical staging, thoracoabdominal-pelvic CT scan, endoscopic ultrasound and PET or PET/CT are used. Other useful explorations are: barium swallow, endoscopic mucosal resection or endoscopic submucosal dissection (for assessment in initial stages) and staging laparoscopy. Once the resectability of the tumor has been established, the operability of the tumor should be assessed according to the patient's condition.

PURPOSE: Biofeedback therapy (BT) is a simple and effective technique for managing outlet constipation and fecal incontinence. Several clinical factors are known to predict BT response, but a 50% failure rate persists. Better selection of BT responsive patients is required. We aimed to determine whether the defecation disorder type per high-resolution manometry (HRM) was predictive of BT response. METHODS: We analyzed clinical, manometric, and ultrasound endoscopic data from patients who underwent BT in our department between January 2015 and January 2016. Patients were classified into four groups per the following defecation disorder classification criteria: rectal pressure > 40 mmHg and anal paradoxical contraction (type I); rectal pressure < 40 mmHg and anal paradoxical contraction (type II); rectal pressure > 40 mmHg and incomplete anal relaxation (type III); and rectal pressure < 40 mmHg and incomplete anal relaxation (type IV). An experienced single operator conducted ten weekly 20-min sessions. Efficacy was evaluated with the visual analog scale. RESULTS: Of 92 patients, 47 (50.5%) responded to BT. Type IV and type II defecation disorders were predictive of success (p = 0.03) (OR = 5.03 [1.02; 24.92]) and failure (p = 0.05) (OR = 0.41 [0.17; 0.99]), respectively. The KESS score severity before BT (p = 0.03) (OR = 0.9 [0.81; 0.99]) was also predictive of failure. CONCLUSION: The manometry types identified according to the defecation disorder classification criteria were predictive of BT response. Our data confirm the role of three-dimensional HRM in the therapeutic management of anorectal functional disorders.

BACKGROUND: One of the most feared complications with the use of cyanoacrylate for treatment of gastric varices is the occurrence of potentially life-threatening systemic embolism. Thus, endoscopists are turning towards new techniques, including endoscopic coiling, as a potentially safer and more effective treatment option. However, no studies have been performed comparing the two techniques. OBJECTIVE: This study aims to compare the safety and efficacy of endoscopic ultrasound guided coil and cyanoacrylate injection versus the conventional technique of injection of cyanoacrylate alone. DESIGN: A pilot randomized controlled trial. METHODS: Patients randomized into group I were treated with coil and cyanoacrylate, and those in group II with cyanoacrylate alone. Flow within the varix was evaluated immediately after the treatment session and one month following initial treatment. If thrombosis was confirmed, additional follow-up was performed 4 and 10 months following initial treatment. All patients underwent a thoracic computerized tomography scan after the procedure. RESULTS: A total of 32 patients, 16 in each group, were followed for an average of 9.9 months (range 1-26 months). Immediately after the procedure, 6 (37.5%) group-I patients and 8 (50%) group-II patients presented total flow reduction in the treated vessel (P=0.476). After 30 days, 11 (73.3%) group-I patients and 12 (75%) group-II patients were found to have varix thrombosis. In both groups, the majority of patients required only one single session for varix obliteration (73.3% in group I versus 80% in group II). Asymptomatic pulmonary embolism occurred in 4 (25%) group-I patients and 8 (50%) group-II patients (P=0.144). No significant difference between the groups was observed. CONCLUSION: There is no statistical difference between endoscopic ultrasound guided coils plus cyanoacrylate versus conventional cyanoacrylate technique in relation to the incidence of embolism. However, a greater tendency towards embolism was observed in the group treated using the conventional technique. Both techniques have similar efficacy in the obliteration of varices. Given the small sample size of our pilot data, our results are insufficient to prove the clinical benefit of the combined technique, and do not yet justify its use, especially in light of higher cost. Further studies with larger sample size are warranted.

ABSTRACT BACKGROUND: The gastroesophageal reflux disease (GERD) is the most common esophageal disease in medical practice, and it is suspected according to patients' symptoms. GERD can be classified in erosive esophagitis (EE) according to the presence of upper gastrointestinal endoscopy findings. OBJECTIVE: To evaluate endoscopic findings in patients with symptoms suggestive of GERD comparing epicemiological and risk factors. METHODS: Upper endoscopy reports were examined retrospectively from patients with symptoms of GERD such as heartburn, regurgitation, cough, throat clearing, globus and chest pain. EE was determined based on Los Angeles classification. Comparisons between risk factors in EE and non-EE groups were done with statistical analysis. RESULTS: A total of 984 endoscopic reports were examined and 676 selected for analysis (281 with EE and 395 with non-EE form). Most were female 381 (56.36%) with a mean age of 44.01±15.40 years. Hiatal hernia was present in 47(6.96%) and smoking in 41(6.07%). Univariate logistic regression showed that male (OR=2.24, CI 95%, 1.63-3.06) and hiatal hernia (OR=4.52, CI 95%, 2.30-8.89) were independent predictors of erosions in the EE group. The presence of hiatal hernia (OR=12.04, CI 95%, 3.57-40.62), smoking (OR=8.46, CI 95%, 3.28-31.32) and aged patients (OR=8.01, CI 95%, 2.42-26.49) were also indicated as a risk factor for severe EE (grades C and D of Los Angeles). CONCLUSION Male gender and hiatal hernia were associated with EE. Aged patients, smoking and hiatal hernia were related to severe EE. It is suggested that the risk factors for EE and non-EE types are different. Cohort studies are necessary to identify the exact mechanisms involved in each disease form.
RESUMO CONTEXTO: A doença do refluxo gastroesofágico (DRGE) é uma das doenças digestivas mais comuns na prática médica e deve ser suspeitada de acordo com os seus sintomas clínicos, podendo ser classificada em esofagite erosiva (EE) de acordo com os achados de endoscopia. OBJETIVO: Avaliar os achados endoscópicos em pacientes com sintomas sugestivos de DGRE comparando fatores de risco e epidemiológicos. MÉTODOS: Resultados de endoscopias digestiva foram examinados retrospectivamente de pacientes com sintomas relacionados com DRGE como pirose, regurgitação, tosse, pigarro, globus e dor torácica. EE foi determinada de acordo com a classificação de Los Angeles. Comparação de fatores de risco entre os grupos EE e não-EE foram feitos com análise estatística. RESULTADOS: Um total de 984 endoscopias foram examinadas e 676 endoscopias selecionadas para análise (281 com EE e 395 sem EE). A maioria dos pacientes era do sexo feminino 381 (56,36%) com uma idade média de 44,01±15,40 anos. Hérnia hiatal esteve presente em 47 (6,96%) e tabagismo em 41 (6,07%). Regressão logística uni variada mostrou que sexo masculino (OR=2,24 - IC 95%: 1,63-3,06) e hérnia hiatal (OR=4,52 - CI 95%: 2,30-8,89) foram fatores de risco independentes de EE. A presença de hérnia hiatal (OR=12,04 - CI 95%: 3,57-40,62), tabagismo (OR=8,46 - CI 95%: 3,28-31,32) e pacientes idosos (OR=8,01 - CI 95%, 2,42-26,49) foram fatores de risco no grupo de EE grave (classes C e D de Los Angeles). CONCLUSÃO: Sexo masculino e hérnia hiatal foram associados com EE. Idade avançada, tabagismo e hérnia hiatal foram relacionados à forma grave de EE. É sugerido que os fatores de risco de pacientes com e sem EE sejam diferentes. Estudos de coorte são necessários para identificar os mecanismos exatos envolvidos em cada forma da doença.

ABSTRACT BACKGROUND: One of the most feared complications with the use of cyanoacrylate for treatment of gastric varices is the occurrence of potentially life-threatening systemic embolism. Thus, endoscopists are turning towards new techniques, including endoscopic coiling, as a potentially safer and more effective treatment option. However, no studies have been performed comparing the two techniques. OBJECTIVE: This study aims to compare the safety and efficacy of endoscopic ultrasound guided coil and cyanoacrylate injection versus the conventional technique of injection of cyanoacrylate alone. DESIGN: A pilot randomized controlled trial. METHODS: Patients randomized into group I were treated with coil and cyanoacrylate, and those in group II with cyanoacrylate alone. Flow within the varix was evaluated immediately after the treatment session and one month following initial treatment. If thrombosis was confirmed, additional follow-up was performed 4 and 10 months following initial treatment. All patients underwent a thoracic computerized tomography scan after the procedure. RESULTS: A total of 32 patients, 16 in each group, were followed for an average of 9.9 months (range 1-26 months). Immediately after the procedure, 6 (37.5%) group-I patients and 8 (50%) group-II patients presented total flow reduction in the treated vessel (P=0.476). After 30 days, 11 (73.3%) group-I patients and 12 (75%) group-II patients were found to have varix thrombosis. In both groups, the majority of patients required only one single session for varix obliteration (73.3% in group I versus 80% in group II). Asymptomatic pulmonary embolism occurred in 4 (25%) group-I patients and 8 (50%) group-II patients (P=0.144). No significant difference between the groups was observed. CONCLUSION: There is no statistical difference between endoscopic ultrasound guided coils plus cyanoacrylate versus conventional cyanoacrylate technique in relation to the incidence of embolism. However, a greater tendency towards embolism was observed in the group treated using the conventional technique. Both techniques have similar efficacy in the obliteration of varices. Given the small sample size of our pilot data, our results are insufficient to prove the clinical benefit of the combined technique, and do not yet justify its use, especially in light of higher cost. Further studies with larger sample size are warranted.
RESUMO CONTEXTO: Uma das complicações mais temidas com o uso de cianoacrilato para tratamento de varizes gástricas é a ocorrência de embolia sistêmica potencialmente fatal. Assim, os endoscopistas estão se aprimorando com novas técnicas, incluindo o uso de coils endoscópico, como uma opção de tratamento potencialmente mais segura e eficaz. No entanto, nenhum estudo foi realizado comparando as duas técnicas. OBJETIVO: Este estudo tem como objetivo comparar a segurança e eficácia da injeção de coil com cianoacrilato guiados por ultrassom endoscópico versus a técnica convencional de injeção de cianoacrilato. DESIGN: Um ensaio piloto controlado aleatoriamente. MÉTODOS: Os pacientes randomizados para o grupo I foram tratados com coil + cianoacrilato e os do grupo II apenas com cianoacrilato. O fluxo dentro da variz foi avaliado imediatamente após a sessão de tratamento e um mês após o tratamento inicial. Se a trombose foi confirmada, o acompanhamento adicional era realizado em 4 e 10 meses após o tratamento inicial. Todos os pacientes foram submetidos a uma tomografia computadorizada torácica após o procedimento. RESULTADOS: Um total de 32 pacientes, 16 em cada grupo, foram acompanhados por uma média de 9,9 meses (variação de 1-26 meses). Imediatamente após o procedimento, 6 (37,5%) pacientes do grupo I e 8 (50%) pacientes do grupo II apresentaram redução total do fluxo no vaso tratado (P=0,476). Após 30 dias, 11 (73,3%) pacientes do grupo I e 12 (75%) pacientes do grupo II apresentaram trombose da variz. Em ambos os grupos, a maioria dos pacientes necessitou de apenas uma única sessão para obliteração da variz (73,3% no grupo I versus 80% no grupo II). Embolia pulmonar assintomática ocorreu em 4 (25%) pacientes do grupo I e em 8 (50%) pacientes no grupo II (P=0,144). Nenhuma diferença significativa entre os grupos foi observada. CONCLUSÃO Apesar de não haver diferença estatística entre os dois grupos em relação à incidência de embolia neste estudo piloto, observou-se maior tendência de embolia no grupo tratado pela técnica convencional.

BACKGROUND: Bilateral thoracoscopic stellectomy has antiarrhythmic effects, but the procedure is invasive with associated morbidity. Sympathetic nerves from both stellate ganglia form the deep cardiac plexus (CP) in the aortopulmonary window, anterior to the trachea. OBJECTIVE: The purpose of this study was to demonstrate a novel and minimally invasive transtracheal approach to block the CP in porcine models. METHODS: In 12 Yorkshire pigs, right (RSG) and left (LSG) stellate ganglia were electrically stimulated and sympathetic baseline response recorded (hemodynamic parameters and T-wave pattern). Aortopulmonary window was accessed transtracheally with endobronchial ultrasound guidance, and local stimulation of CP confirmed the location. Injection of 1% lidocaine (n = 10) or saline solution (n = 2) was performed, and RSG and LSG responses were re-evaluated and compared with baseline. RESULTS: Transtracheal lidocaine injection into the CP successfully blocked bilateral sympathetic induced changes (%) in T-wave amplitude (282.8% ± 152.2% vs 20.1% ± 16.5%; P <.001 [LSG]; 338.9% ± 189.8% vs 28% ± 18.3%; P <.001 [RSG]), Tp-Te interval (87.9% ± 37.2% vs 6.9% ± 6.7%; P <.001 [LSG]; 32.6% ± 27.4% vs 6.9% ± 4.7%; P <.035 [RSG]), and left ventricular dP/dTmax (148.3% ± 108.5% vs 16.5% ± 13.4%; P <.001 [LSG]; 243.1% ± 105.2% vs 19.0% ± 12.4%; P <.001 [RSG]). RSG-induced elevations of systemic, left ventricular, and pulmonary arterial pressures were blocked by lidocaine injection into CP (P <.005 for all comparisons). Stellate ganglia response was not affected in sham studies. No complications were observed during the procedures. CONCLUSION: Minimally invasive transtracheal injection of lidocaine into the CP blocked the sympathetic response of either RSG and LSG. Transtracheal assessment of CP may allow for minimally invasive and selective ablation of cardiac innervation, extending the cardiac sympathectomy denervation benefits to those not suitable for surgery.

RATIONALE: Ultrasonography-guided gastrojejunostomy (EUS-GJ) might be a safe, innovative and minimally invasive interventional treatment for patients with gastric outlet obstruction (GOO) as an alternative to the surgical approach. To date, few cases have been reported in the literature. PATIENT CONCERNS: A case of pancreatic head carcinoma with obstructive jaundice occurred in a 78-year-old man with a prior history of pancreatic head cancer. Biliary stent placement was conducted 1 year earlier. DIAGNOSES: The patient was diagnosed with pancreatic cancer, pulmonary infection, pyloric obstruction, and biliary stent implantation. INTERVENTIONS: EUS-GJ was performed. The wire and a double-balloon catheter reached the position of stenosis, then a double mushroom head bracket was released under EUS. The position was confirmed via X-ray. OUTCOMES: The symptoms of obstruction were alleviated. No recurrence of obstruction, bleeding, perforation, and other complications occurred for the following 1.5 months while he died because of whole body spread of pancreatic cancer. LESSONS: EUS-GJ may be reliable and effective for patients with GOO.
