RESUMO

BACKGROUND & AIMS: The use of computer-aided detection (CAD) increases the adenoma detection rates (ADRs) during colorectal cancer (CRC) screening/surveillance. This study aimed to evaluate the requirements for CAD to be cost-effective and the impact of CAD on adenoma detection by endoscopists with different ADRs. METHODS: We developed a semi-Markov microsimulation model to compare the effectiveness of traditional colonoscopy (mean ADR, 26%) to colonoscopy with CAD (mean ADR, 37%). CAD was modeled as having a $75 per-procedure cost. Extensive 1-way sensitivity and threshold analysis were performed to vary cost and ADR of CAD. Multiple scenarios evaluated the potential effect of CAD on endoscopists' ADRs. Outcome measures were reported in incremental cost-effectiveness ratios, with a willingness-to-pay threshold of $100,000/quality-adjusted life year. RESULTS: When modeling CAD improved ADR for all endoscopists, the CAD cohort had 79 and 34 fewer lifetime CRC cases and deaths, respectively, per 10,000 persons. This scenario was dominant with a cost savings of $143 and incremental effectiveness of 0.01 quality-adjusted life years. Threshold analysis demonstrated that CAD would be cost-effective up to an additional cost of $579 per colonoscopy, or if it increases ADR from 26% to at least 30%. CAD reduced CRC incidence and mortality when limited to improving ADRs for low-ADR endoscopists (ADR <25%), with 67 fewer CRC cases and 28 CRC deaths per 10,000 persons compared with traditional colonoscopy. CONCLUSIONS: As CAD is implemented clinically, it needs to improve mean ADR from 26% to at least 30% or cost less than $579 per colonoscopy to be cost-effective when compared with traditional colonoscopy. Further studies are needed to understand the impact of CAD when used in community practice.

RESUMO

PURPOSE OF REVIEW: The burdens of pancreatic ductal adenocarcinoma (PDAC) and acute pancreatitis are increasing globally. We reviewed current literature on whether acute pancreatitis is a causal factor for PDAC and examined clinical manifestations of PDAC-associated acute pancreatitis. RECENT FINDINGS: Recent findings detail the timing of acute pancreatitis before and after PDAC occurrence, further solidifying the evidence for PDAC-associated acute pancreatitis and for acute pancreatitis as a causal risk factor for PDAC. The risk of PDAC remains elevated above the general population in patients with distant history of acute pancreatitis. PDAC risk also increases with recurrent acute pancreatitis episodes, independent of smoking and alcohol. Mechanisms linking acute pancreatitis to PDAC include inflammation and neutrophil infiltration, which can be attenuated by suppressing inflammation and/or epigenetic modulation, thus slowing the progression of acinar-to-ductal metaplasia. Clinical presentation and management of acute pancreatitis in the context of PDAC are discussed, including challenges acute pancreatitis poses in the diagnosis and treatment of PDAC, and novel interventions for PDAC-associated acute pancreatitis. SUMMARY: PDAC risk may be reduced with improved acute pancreatitis prevention and treatment, such as antiinflammatories or epigenetic modulators. Increased acute pancreatitis and PDAC burden warrant more research on better diagnosis and management of PDAC-associated acute pancreatitis.

RESUMO

BACKGROUND AND AIMS: Complete closure after endoscopic resection of large nonpedunculated colorectal lesions (LNPCLs) can reduce delayed bleeding but is challenging with conventional through-the-scope (TTS) clips alone. The novel dual-action tissue (DAT) clip has clip arms that open and close independently of each other, facilitating tissue approximation. We aimed to evaluate the rate of complete closure and delayed bleeding with the DAT clip after endoscopic resection of LNPCLs. METHODS: This was a multicenter prospective cohort study of all patients who underwent defect closure with the DAT clip after EMR or endoscopic submucosal dissection (ESD) of LNPCLs ≥20 mm from July 2022 to May 2023. Delayed bleeding was defined as a bleeding event requiring hospitalization, blood transfusion, or any intervention within 30 days after the procedure. Complete closure was defined as apposition of mucosal defect margins without visible submucosal areas <3 mm along the closure line. RESULTS: One hundred seven patients (median age, 64 years; 42.5% women) underwent EMR (n = 63) or ESD (n = 44) of LNPCLs (median size, 40 mm; 74.8% right-sided colon) followed by defect closure. Complete closure was achieved in 96.3% (n = 103) with a mean of 1.4 ± .6 DAT clips and 2.9 ± 1.8 TTS clips. Delayed bleeding occurred in 1 patient (.9%) without requiring additional interventions. CONCLUSIONS: The use of the DAT clip in conjunction with TTS clips achieved high complete defect closure after endoscopic resection of large LNPCLs and was associated with a .9% delayed bleeding rate. Future comparative trials and formal cost-analyses are needed to validate these findings. (Clinical trial registration number: NCT05852457.).

RESUMO

BACKGROUND AND AIMS: Despite the significant morbidity associated with gastric variceal bleeding, there is a paucity of high-quality data regarding optimal management. EUS-guided coil injection therapy (EUS-COIL) has recently emerged as a promising endoscopic modality for the treatment of gastric varices (GV), particularly compared with traditional direct endoscopic glue injection. Although there are data on the feasibility and safety of EUS-COIL in the management of GV, these have been limited to select centers with particular expertise. The aim of this study was to report the first U.S. multicenter experience of EUS-COIL for the management of GV. METHODS: This retrospective analysis included patients with bleeding GV or GV at risk of bleeding who underwent EUS-COIL at 10 U.S. tertiary care centers between 2018 and 2022. Baseline patient and procedure-related information was obtained. EUS-COIL entailed the injection of .018 inch or .035 inch hemostatic coils using a 22-gauge or 19-gauge FNA needle. Primary outcomes were technical success (defined as successful deployment of coil into varix under EUS guidance with diminution of Doppler flow), clinical success (defined as cessation of bleeding if present and/or absence of bleeding at 30 days' postintervention), and intraprocedural and postprocedural adverse events. RESULTS: A total of 106 patients were included (mean age 60.4 ± 12.8 years; 41.5% female). The most common etiology of GV was cirrhosis (71.7%), with alcohol being the most common cause (43.4%). Overall, 71.7% presented with acute GV bleeding requiring intensive care unit stay and/or blood transfusion. The most common GV encountered were isolated GV type 1 (60.4%). A mean of 3.8 ± 3 coils were injected with a total mean length of 44.7 ± 46.1 cm. Adjunctive glue or absorbable gelatin sponge was injected in 82% of patients. Technical success and clinical success were 100% and 88.7%, respectively. Intraprocedural adverse events (pulmonary embolism and GV bleeding from FNA needle access) occurred in 2 patients (1.8%), and postprocedural adverse events occurred in 5 (4.7%), of which 3 were mild. Recurrent bleeding was observed in 15 patients (14.1%) at a mean of 32 days. Eighty percent of patients with recurrent bleeding were successfully re-treated with repeat EUS-COIL. No significant differences were observed in outcomes between high-volume (>15 cases) and low-volume (<7 cases) centers. CONCLUSIONS: This U.S. multicenter experience on EUS-COIL for GV confirms high technical and clinical success with low adverse events. No significant differences were seen between high- and low-volume centers. Repeat EUS-COIL seems to be an effective rescue option for patients with recurrent bleeding GV. Further prospective studies should compare this modality versus other interventions commonly used for GV.

RESUMO

OBJECTIVES: No study has explored whether availability of endoscopic retrograde cholangiopancreatography (ERCP) is adequate and equitable across US children's hospitals. We hypothesized that ERCP availability and utilization differs by geography and patient factors. METHODS: Healthcare encounter data from 2009 to 2019 on children with pancreatic and biliary diseases from the Pediatric Health Information System were analyzed. ERCP availability was defined as treatment at a hospital that performed pediatric ERCP during the year of service. RESULTS: From 2009 to 2019, 37,946 children (88,420 encounters) had a potential pancreatic or biliary indication for ERCP; 7066 ERCPs were performed. The commonest pancreatic diagnoses leading to ERCP were chronic (47.2%) and acute pancreatitis (43.2%); biliary diagnoses were calculus (68.3%) and obstruction (14.8%). No ERCP was available for 25.0% of pancreatic encounters and 8.1% of biliary encounters. In multivariable analysis, children with public insurance, rural residence, or of Black race were less likely to have pancreatic ERCP availability; those with rural residence or Asian race were less likely to have biliary ERCP availability. Black children or those with public insurance were less likely to undergo pancreatic ERCP where available. Among encounters for calculus or obstruction, those of Black race or admitted to hospitals in the West were less likely to undergo ERCP when available. CONCLUSIONS: One-in-four children with pancreatic disorders and one-in-12 with biliary disorders may have limited access to ERCP. We identified racial and geographic disparities in availability and utilization of ERCP. Further studies are needed to understand these differences to ensure equitable care.

RESUMO

BACKGROUND: Adult patients with biliary acute pancreatitis (BAP) or choledocholithiasis who do not undergo cholecystectomy on index admission have worse outcomes. Given the paucity of data on the impact of cholecystectomy during index hospitalization in children, we examined readmission rates among pediatric patients with BAP or choledocholithiasis who underwent index cholecystectomy versus those who did not. METHODS: Retrospective study of children (< 18 years old) admitted with BAP, without infection or necrosis (ICD-10 K85.10), or choledocholithiasis (K80.3x-K80.7x) using the 2018 National Readmission Database (NRD). Exclusion criteria were necrotizing pancreatitis with or without infected necrosis and death during index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmission. RESULTS: In 2018, 1122 children were admitted for index BAP (n = 377, 33.6%) or choledocholithiasis (n = 745, 66.4%). Mean age at admission was 13 (SD 4.2) years; most patients were female (n = 792, 70.6%). Index cholecystectomy was performed in 663 (59.1%) of cases. Thirty-day readmission rate was 10.9% in patients who underwent cholecystectomy during that index admission and 48.8% in those who did not (p < 0.001). In multivariable analysis, patients who underwent index cholecystectomy had lower odds of 30-day readmission than those who did not (OR 0.16, 95% CI 0.11-0.24, p < 0.001). CONCLUSIONS: Index cholecystectomy was performed in only 59% of pediatric patients admitted with BAP or choledocholithiasis but was associated with 84% decreased odds of readmission within 30 days. Current guidelines should be updated to reflect these findings, and future studies should evaluate barriers to index cholecystectomy.

RESUMO

BACKGROUND: Adult patients with cholecystitis who do not undergo cholecystectomy on index admission have worse outcomes, however, there is a paucity of data of the role of cholecystectomy during index hospitalization in the pediatric population. Our aim was to determine outcomes and readmission rates among pediatric patients with cholecystitis who underwent index cholecystectomy versus those who did not. METHODS: We performed a retrospective study of pediatric (< 18 years old) admitted with acute cholecystitis (AC) requiring hospitalization using the 2018 National Readmission Database (NRD). Exclusion criteria included age ≥ 18 years and death on index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmissions. RESULTS: We identified 550 unique index acute cholecystitis admissions. Mean age was 14.6 ± 3.0 years. Majority of patients were female (n = 372, 67.6%). Index cholecystectomy was performed in (n = 435, 79.1%) of cases. Thirty-day readmission rate was 2.8% in patients who underwent index cholecystectomy and 22.6% in those who did not (p < 0.001). On multivariable analysis, patients who did not undergo index cholecystectomy had higher odds of 30-day readmission than those who did not (OR 10.66, 95% CI 5.06-22.45, p < 0.001). Female patients also had higher odds of 30-day readmission compared to males (OR 3.37, 95% CI 1.31-8.69). CONCLUSIONS: Patients who did not undergo index cholecystectomy had over tenfold increase in odds of 30-day readmission. Further research is required to understand the barriers to index cholecystectomy despite society recommendations and clear clinical benefit.

RESUMO

Background: Studies suggest that telemedicine worsens health care disparities in certain groups, partly owing to a lack of access to appropriate technology or poor technological literacy. Our aim was to use clinic no-show data to determine the impact of telemedicine on patient access to care in the ambulatory gastroenterology setting. Methods: Single-center retrospective study of ambulatory in-person and telemedicine clinic appointments comparing the 15-month prepandemic (PP) with the first 15 months during the pandemic (DTP) using an administrative database. Statistical analysis was performed using univariate and multivariable logistic regression. Results: About 9,746 and 12,808 patient-encounters were scheduled PP and DTP respectively. The no-show rate decreased from 9.8% to 6.9% DTP (p < 0.001). The no-show rate decreased for Black (p = 0.02) and non-Hispanic White patients (p = 0.018). The no-show rate increased for LatinX (p < 0.001) and Asian (p = 0.007) patients. In multivariate analysis, older patients and patients identifying as Black, Asian, or LatinX all had higher odds of no-show DTP (p < 0.05 for all). Patients from high-income counties were 43% less likely to no-show than those in the lowest income counties. Conclusions: The transition to telemedicine improves health care access by decreasing the overall no-show rate. Some groups have been negatively affected, including the older, lower income, LatinX, and Asian populations. Future studies should aim to identify the risk factors within these populations that can be modified to increase health care participation, including targeted application of in-person visits, and improved technology to drive engagement.

RESUMO

BACKGROUND & AIMS: The Cotton Consensus (CC) criteria for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) may not capture post-ERCP morbidity. PAN-PROMISE, a patient-reported outcome measure (PROM), was developed to quantify acute pancreatitis-related morbidity. This study aims to determine the value of PAN-PROMISE in independently defining ERCP-related morbidity. METHODS: We conducted a prospective cohort study of patients undergoing ERCP at 2 academic centers from September 2021 to August 2022. We administered PAN-PROMISE and assessed quality of life and work productivity at baseline, 48 to 72 hours, 7 days, and 30 days following ERCP. PEP was defined by a 3-physician committee using the CC criteria. We defined high morbidity following ERCP (elevated PROM) by an increase of PAN-PROMISE score of >7 at 7 days post-procedure. The McNemar test assessed discordance between PEP and elevated-PROM. RESULTS: A total of 679 patients were enrolled. Choledocholithiasis (30%) and malignant biliary obstruction (29%) were the main indications for ERCP. Thirty-two patients (4.7%) developed PEP. One hundred forty-seven patients (21.6%) had an elevated PROM, whereas only 20 of them (13.4%) had PEP by the CC criteria (P < .001 for discordance). An elevated PROM strongly correlated with lower physical quality of life and increased direct and indirect health care costs ($80 and $25 per point increase in PAN-PROMISE, respectively). Patients with pancreatic cancer (odds ratio, 4.52; 95% confidence interval, 1.68-10.74) and primary sclerosing cholangitis (odds ratio, 1.79; 95% confidence interval, 1.29-2.45) had the highest odds of elevated PROM. CONCLUSIONS: A substantial number of patients experience significant morbidity after ERCP despite not developing PEP or other adverse events. Future studies are needed to characterize better the reasons behind this increase in symptoms and potential interventions to reduce the symptom burden post-ERCP. CLINICALTRIALS: gov number, NCT05310409.

RESUMO

BACKGROUND AND AIMS: Rapid on-site-evaluation (ROSE) with an in-room cytopathologist (ROSE-P) has been shown to improve the diagnostic yield of specimens obtained from patients undergoing EUS-guided FNA or fine-needle biopsy sampling (EUS-FNAB) of pancreatic lesions. Recently, there has been an increased interest and use of ROSE using telecytology (ROSE-T) to optimize clinical workflows and to address social distancing mandates created during the coronavirus disease 2019 pandemic. The purpose of this study was to compare diagnostic outcomes of ROSE-P and ROSE-T. METHODS: A single-center cohort study of patients who underwent EUS-FNAB of solid pancreatic lesions with ROSE was conducted. The primary outcome was overall diagnostic yield of cancer. All patients who underwent EUS-FNAB were entered into a prospectively maintained database. Statistical analyses were performed using descriptive statistics and univariate analysis. RESULTS: There were 165 patients in each arm. There was no difference in diagnostic yield between ROSE-P and ROSE-T (96.4% vs 94.5%, P = .428). ROSE-T was associated with an increased use of 22-gauge needles (P = .006) and more needle passes (P < .001). No significant differences were found in age, gender, lesion size, needle type, procedure times, or adverse events between the 2 groups (P < .05 for all). More pancreatic tail lesions were sampled in the ROSE-P group (P < .001). CONCLUSIONS: ROSE-T was not associated with any difference in final histologic diagnosis for EUS-FNAB of solid pancreatic masses. This has important implications for optimizing clinical workflows.

RESUMO

BACKGROUND AND AIMS: Palliation of malignant gastric outlet obstruction (mGOO) allows resumption of peroral intake. Although surgical gastrojejunostomy (SGJ) provides durable relief, it may be associated with a higher morbidity, interfere with chemotherapy, and require an optimum nutritional status. EUS-guided gastroenterostomy (EUS-GE) has emerged as a minimally invasive alternative. We aimed to conduct the largest comparative series to date between EUS-GE and SGJ for mGOO. METHODS: This multicenter retrospective study included consecutive patients undergoing SGJ or EUS-GE at 6 centers. Primary outcomes included time to resumption of oral intake, length of stay (LOS), and mortality. Secondary outcomes included technical and clinical success, reintervention rates, adverse events (AEs), and resumption of chemotherapy. RESULTS: A total of 310 patients were included (EUS-GE, n = 187; SGJ, n = 123). EUS-GE exhibited significantly lower time to resumption of oral intake (1.40 vs 4.06 days, P < .001), at lower albumin levels (2.95 vs 3.33 g/dL, P < .001), and a shorter LOS (5.31 vs 8.54 days, P < .001) compared with SGJ; there was no difference in mortality (48.1% vs 50.4%, P = .78). Technical (97.9% and 100%) and clinical (94.1% vs 94.3%) success was similar in the EUS-GE and SGJ groups, respectively. EUS-GE had lower rates of AEs (13.4% vs 33.3%, P < .001) but higher reintervention rates (15.5% vs 1.63%, P < .001). EUS-GE patients exhibited significantly lower interval time to resumption of chemotherapy (16.6 vs 37.8 days, P < .001). Outcomes between the EUS-GE and laparoscopic (n = 46) surgical approach showed that EUS-GE had shorter interval time to initiation/resumption of oral intake (3.49 vs 1.46 days, P < .001), decreased LOS (9 vs 5.31 days, P < .001), and a lower rate of AEs (11.9% vs 17.9%, P = .003). CONCLUSIONS: This is the largest study to date showing that EUS-GE can be performed among nutritionally deficient patients without affecting the technical and clinical success compared with SGJ. EUS-GE is associated with fewer AEs while allowing earlier resumption of diet and chemotherapy.

RESUMO

Deep sedation without tracheal intubation (monitored anaesthesia care) and general anaesthesia with tracheal intubation are commonly used anaesthesia techniques for endoscopic retrograde cholangiopancreatography (ERCP). There are distinct pathophysiological differences between monitored anaesthesia care and general anaesthesia that need to be considered depending on the nature and severity of the patient's underlying disease, comorbidities, and procedural risks. An international group of expert anaesthesiologists and gastroenterologists created clinically relevant questions regarding the merits and risks of monitored anaesthesia care vs general anaesthesia in specific clinical scenarios for planning optimal anaesthetic approaches for ERCP. Using a modified Delphi approach, the group created practical recommendations for anaesthesiologists, with the aim of reducing the incidence of perioperative adverse outcomes while maximising healthcare resource utilisation. In the majority of clinical scenarios analysed, our expert recommendations favour monitored anaesthesia care over general anaesthesia. Patients with increased risk of pulmonary aspiration and those undergoing prolonged procedures of high complexity were thought to benefit from general anaesthesia with tracheal intubation. Patient age and ASA physical status were not considered to be factors for choosing between monitored anaesthesia care and general anaesthesia. Monitored anaesthesia care is the favoured anaesthesia plan for ERCP. An individual risk-benefit analysis that takes into account provider and institutional experience, patient comorbidities, and procedural risks is also needed.

RESUMO

The evolution of endoscopic ultrasound (EUS) from a diagnostic to a therapeutic procedure has resulted in a paradigm shift toward endoscopic management of disease states that previously required percutaneous or surgical approaches. The past few years have seen additional techniques and devices that have enabled endoscopists to expand its diagnostic and therapeutic capabilities. Some of these techniques initially were reported more than a decade ago; however, with further device development and refinement in techniques there is potential for expanding the application of these techniques and new technologies to a broader group of interventional gastroenterologists. Lack of formalized training, devices, and prospective data regarding their use in addition to a scarcity of guidelines on implementation of these technologies into clinical practice are contributing factors impeding the growth of the field of interventional EUS. In April 2019, the American Gastroenterological Association's Center for Gastrointestinal Innovation and Technology conducted its annual Tech Summit and a key session focused on interventional EUS. This article is a White Paper generated from the conference, discusses the published literature pertaining to the topic of interventional EUS, and outlines a proposed framework for the implementation of interventional EUS techniques into clinical practice. Three primary areas of interventional EUS are addressed: (1) EUS-guided access; (2) EUS-guided tumor ablation; and (3) endohepatology. There was general agreement among participants on several key components. The introduction of these novel interventions requires better tools, more data on safety/outcomes, and improved training for endoscopists. Participants also agreed that widespread implementation and use of these techniques will require support from Gastrointestinal Societies and other key stakeholders including payers. Continued work by the Gastrointestinal Societies and manufacturers to provide training programs, appropriate equipment/work environments, and policies that motivate endoscopists to adopt new techniques is essential for growing the field of interventional EUS.

RESUMO

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Colon Cancer focuses on systemic therapy options for the treatment of metastatic colorectal cancer (mCRC), because important updates have recently been made to this section. These updates include recommendations for first-line use of checkpoint inhibitors for mCRC, that is deficient mismatch repair/microsatellite instability-high, recommendations related to the use of biosimilars, and expanded recommendations for biomarker testing. The systemic therapy recommendations now include targeted therapy options for patients with mCRC that is HER2-amplified, or BRAF V600E mutation-positive. Treatment and management of nonmetastatic or resectable/ablatable metastatic disease are discussed in the complete version of the NCCN Guidelines for Colon Cancer available at NCCN.org. Additional topics covered in the complete version include risk assessment, staging, pathology, posttreatment surveillance, and survivorship.

RESUMO

BACKGROUND AND AIMS: The American Society for Gastrointestinal Endoscopy recommends prophylactic pancreatic duct stent placement (PPS) and rectal nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce the incidence and severity of post-ERCP pancreatitis (PEP) in high-risk individuals and suggests that rectal indomethacin may decrease the risk and severity of PEP in average-risk individuals. The European Society for Gastrointestinal Endoscopy recommends rectal indomethacin for all patients undergoing ERCP. Previous surveys of European endoscopists revealed low adoption of PPS or rectal NSAIDs to prevent PEP. We sought to capture current practice in the prevention of PEP among endoscopists in the United States involved in advanced endoscopy fellowship programs. METHODS: An anonymous online 16-item survey was e-mailed to 233 advanced endoscopists involved in advanced endoscopy fellowship programs. RESULTS: Of the 233 endoscopists who were invited to participate, 62 responded (26.7%). Most respondents reported working in tertiary referral centers (57; 95.0%) and performing ERCP for greater than 5 years (44; 74.6%). All respondents (60; 100.0%) reported working with fellows. Most PPS users (41; 72.0%) reported use of PPS in high-risk patients only and using PPS for PEP in ≤25% of ERCPs (38; 64.4%). Most respondents reported using rectal NSAIDs for high-risk patients only (34; 59.7%) compared with respondents (23; 40.1%) who reported using rectal NSAIDs for prevention of PEP in average-risk patients undergoing ERCP. Most respondents (49; 83.0%) also reported using rapid intravenous fluids to prevent PEP. CONCLUSIONS: Among endoscopists involved in advanced endoscopy fellowships in the United States, rectal NSAIDs are used more frequently than PPS in the prevention of PEP. Despite mounting evidence supporting the use of rectal NSAIDs to prevent PEP in average-risk patients, less than half of the respondents in this survey reported such practice.

RESUMO

The NCCN Guidelines for Rectal Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up of patients with rectal cancer. These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines. These updates include clarifying the definition of rectum and differentiating the rectum from the sigmoid colon; the total neoadjuvant therapy approach for localized rectal cancer; and biomarker-targeted therapy for metastatic colorectal cancer, with a focus on new treatment options for patients with BRAF V600E- or HER2 amplification-positive disease.

RESUMO

Sclerosing angiomatoid nodular transformation of spleen is a rare, benign vascular lesion with an uncertain pathogenesis. It has been described as a separate entity through specific histopathological characters. It is usually asymptomatic, occurring commonly in adult females. Only a few cases of paediatric cases have been reported which have been commonly symptomatic. This disease has excellent prognosis after splenectomy, which is the only treatment. We report the case of an eight-year-old girl who presented with distended abdomen and history of bleeding from the nose following a road traffic accident. Examination revealed stunted height, decreased weight, tachypnoea, tachycardia, anaemia and a firm, massive spleen. Lab investigations further revealed microcytic anaemia, thrombocytopenia, deranged platelet profile and low vitamin B12 and folate levels. Computed tomography confirmed enlarged spleen. Therefore, a diagnostic biopsy was planned which confirmed sclerosing angiomatoid nodular transformation of spleen. Splenectomy was successfully performed soon after and the child is now healthy with no remissions of previous symptoms.

RESUMO

BACKGROUND: Ampullary stenosis following Roux-en-Y gastric bypass (RYGB) is increasingly encountered. We describe cases of biliary obstruction from ampullary stenosis and choledocholithiasis to illustrate the associated diagnostic and interventional challenges with this condition. METHODS: We reviewed medical records of patients with prior RYGB who underwent a biliary access procedure or surgery for non-malignant disease from January 2012-December 2018. RESULTS: We identified 15 patients (4 male, 11 female; mean age 53.7 years) who had RYGB on average 11.7 years (range 1-32) years before diagnosis of biliary obstruction. Fourteen patients reported abdominal pain, 5 had nausea/emesis, 12 had elevated liver function tests, and 6 had ascending cholangitis. Mean common bile duct (CBD) diameter at presentation was 16.9 mm (range 4.0-25.0 mm). Operations included 3 transduodenal ampullectomies (2 with biliary bypass), 2 CBD explorations with stone extraction, 1 laparoscopic cholecystectomy alone, 1 Whipple procedure, 1 balloon enteroscopy with sphincterotomy, and 7 transgastric endoscopic retrograde cholangiopancreatography. All ampulla pathology was benign in patients who underwent resection. At follow-up (mean 15.4 months; range 0.23-44.5 months), 12/15 (80%) reported symptom resolution or improvement. DISCUSSION: Ampullary stenosis after RYGB presents challenges for diagnostic evaluation and intervention, often requiring multi-disciplinary expertise. The underlying pathology remains to be elucidated.

RESUMO

Small bowel adenocarcinoma (SBA) is a rare malignancy of the gastrointestinal tract that has increased in incidence across recent years. Often diagnosed at an advanced stage, outcomes for SBA are worse on average than for other related malignancies, including colorectal cancer. Due to the rarity of this disease, few studies have been done to direct optimal treatment, although recent data have shown that SBA responds to treatment differently than colorectal cancer, necessitating a separate approach to treatment. The NCCN Guidelines for Small Bowel Adenocarcinoma were created to establish an evidence-based standard of care for patients with SBA. These guidelines provide recommendations on the workup of suspected SBA, primary treatment options, adjuvant treatment, surveillance, and systemic therapy for metastatic disease. Additionally, principles of imaging and endoscopy, pathologic review, surgery, radiation therapy, and survivorship are described.

RESUMO

BACKGROUND: Percutaneous cholecystostomy tube (PTGBD), endoscopic retrograde cholangiopancreatography with transpapillary gallbladder drainage (TP), and endoscopic ultrasound-guided transmural gallbladder drainage (EGBD) using lumen-apposing metal stents (LAMS) have been offered for gallbladder decompression for acute cholecystitis in high-risk surgical patients. Yet, there are limited data comparing these therapies. Our aim was to compare the safety and efficacy of EGBD to TP and PTGBD for gallbladder drainage. METHODS: We retrospectively collected high-risk surgical patients from six centers with acute cholecystitis who underwent gallbladder drainage by EGBD, TP, or PTGBD. Data included technical success (gallbladder drainage), clinical success (acute cholecystitis resolution), adverse events (AE), and follow-up. RESULTS: From 2010 to 2016, 372 patients underwent gallbladder drainage, with 146 by PTGBD, 124 by TP, and 102 drained by EGBD. Technical (98% vs. 88% vs. 94%; p = 0.004) and Clinical (97% vs. 90% vs. 80%; p < 0.001) success rates were significantly higher with PTGBD and EGBD compared to TP. PTGBD group had statistically significantly higher number of complications as compared to EGBD and TP groups (2 0% vs. 2% vs. 5%; p = 0.01). Mean hospital stay in the EGBD group was significantly less than TP and PTGBD (16 vs. 18 vs. 19 days; p = 0.01), while additional surgical intervention was significantly higher in the PTGBD group compared to the EGBD and TP groups (49% vs. 4% vs. 11%; p < 0.0001). CONCLUSIONS: EGBD with LAMS is an effective and safer alternative to TP and PTGBD for treatment of patients with acute cholecystitis who cannot undergo surgery. EGBD with LAMS has significantly lower overall AEs, hospital stay, and unplanned admissions compared to PTGBD. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01522573.
