RESUMO
BACKGROUND & AIMS: Understanding the burden of pancreatic cystic lesions (PCLs) in the general population is important for clinicians and policymakers. In this systematic review, we sought to estimate the global prevalence of PCLs using magnetic resonance imaging (MRI) and to investigate factors that contribute to its variation. METHODS: We searched MEDLINE, EMBASE, and Cochrane Central, from database inception through February 2023. We included full-text articles that reported the prevalence of PCLs using MRI in the general population. A proportional meta-analysis was performed, and the prevalence of PCLs was pooled using a random-effects model. RESULTS: Fifteen studies with 65,607 subjects were identified. The pooled prevalence of PCLs was 16% (95% confidence interval [CI], 13%-18%; I2 = 99%), most of which were under 10 mm. Age-specific prevalence of PCLs increased from 9% (95% CI, 7%-12%) at 50 to 59 years, to 18% (95% CI, 14%-22%) at 60 to 69 years, 26% (95% CI, 20%-33%) at 70 to 79 years, and 38% at 80 years and above (95% CI, 25%-52%). There was no difference in prevalence between sexes. Subgroup analysis showed higher PCL prevalence when imaging findings were confirmed by independent radiologist(s) (25%; 95% CI, 16%-33%) than when chart review alone was used (5%; 95% CI, 4%-7%; P < .01). There was no independent association of PCL prevalence with geographic location (Europe, North America, or Asia), MRI indication (screening vs evaluation of non-pancreatic pathology), enrollment period, sample size, magnet strength (1.5 vs 3 tesla), and MRI sequence (magnetic resonance cholangiopancreatography vs no magnetic resonance cholangiopancreatography). CONCLUSION: In this systematic review, the global prevalence of PCLs using a highly sensitive noninvasive imaging modality ranged between 13% and 18%.
RESUMO
BACKGROUND AND AIMS: The optimal number of passes to maximize the diagnostic ability of EUS fine-needle biopsy (FNB) of solid pancreatic masses (SPMs) is not well known. We conducted a systematic review to evaluate the impact of the incremental number of passes on diagnostic accuracy, tissue adequacy, and diagnostic yield for EUS-FNB of SPMs. METHODS: We searched MEDLINE, Embase, Scopus, and Cochrane Central for randomized controlled trials comparing per-pass diagnostic outcomes of FNB needles in patients with SPMs. Meta-analysis was conducted using random-effects models. A separate analysis was performed on studies that used contemporary Franseen and fork-tip needles. RESULTS: Overall, 19 randomized controlled trials (N = 3552) were identified. For EUS-FNB of SPMs, 3 passes with any FNB needle outperformed 2 passes for accuracy (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.20-2.09; I2 = 0%), adequacy (OR, 1.97; 95% CI, 1.30-2.83; I2 = 61%), and yield (OR, 2.12; 95% CI, 1.37-3.27; I2 = 14%). Adding a fourth or fifth pass resulted in no significant improvement in diagnostic parameters. When using contemporary FNB needles, adding a second to a single pass significantly improved accuracy (OR, 1.80; 95% CI, 1.23-2.63; I2 = 0%), adequacy (OR, 2.19; 95% CI, 1.65-2.90; I2 = 0%), and yield (OR, 2.72; 95% CI, 1.50-4.95; I2 = 0%). Adding a third pass to a second pass with contemporary needles improved adequacy (OR, 2.96; 95% CI, 1.97-4.46; I2 = 0%) but did not provide better diagnostic accuracy or yield. CONCLUSIONS: Two passes with Franseen or Fork-tip needles and 3 passes with any FNB needle suffice to provide optimal diagnostic performance for EUS-FNB of SPMs, without additional diagnostic benefits with more passes. Our results can inform future guidelines and quality benchmarks.
RESUMO
BACKGROUND: Pancreatic fluid collections (PFCs) may recur after resolution with endoscopic transmural drainage (ETD) and standard stent removal (SSR). Herein, we compared the efficacy and safety of leaving long-term indwelling plastic stents (LTIS) vs. standard stent removal after PFC resolution with ETD. METHODS: We performed a systematic review of MEDLINE, EMBASE, CINAHL, Scopus, and Cochrane databases from inception to September 2022. Full-text articles comparing long-term (> 6 months) outcomes of LTIS and SSR were eligible, as well as single-arm studies with ≥ 10 patients with LTIS. Two independent reviewers selected studies, extracted data, and assessed the risk of bias using the Newcastle-Ottawa Scale. Measured outcomes included the following: (A) PFC recurrence; (B) interventions for PFC recurrence; (C) technical success; and (D) adverse events (AEs). Meta-analysis was carried out using random-effects models. RESULTS: We included 16 studies, encompassing 1285 patients. Compared to SSR after PFC resolution with ETD, LTIS was associated with significantly lower risk of PFC recurrence (3% vs. 23%; OR 0.22 [95%CI 0.09-0.52]; I2 = 45%) and need for interventions (2% vs. 14%; OR 0.35 [95%CI 0.16-0.78]; I2 = 0%). The superiority of LTIS on reducing PFC recurrence was found with walled-off necrosis, with or without disconnected pancreatic duct, and with placement of ≥ 2 LTIS. When using LTIS, the pooled proportion of AEs was 8% (95%CI 4-11%) and technical success was 93% (95%CI 86-99%). CONCLUSIONS: Our results show that LTIS after PFC resolution with ETD is feasible, safe, and superior to SSR in reducing the risk of PFC recurrence and need for interventions.

BACKGROUND: Spontaneous hyperinflation is reported to the Food and Drug Administration as a complication of intragastric balloons. It is postulated that orogastric contamination of the intragastric balloon may cause this phenomenon. We sought to investigate the effects of intentional balloon contamination with gastric contents on intragastric balloon perimeter and contents, whether methylene blue plays a role in preventing spontaneous hyperinflation, and review the available literature on spontaneous hyperinflation. METHODS: Four pairs of balloons with different combinations of sterile saline, orogastric contaminants, and methylene blue were incubated in a 37 °C water bath for six months to simulate physiological conditions with serial measurements of balloon perimeter. Our findings were compared against a systematic review across multiple databases to summarize the available literature. RESULTS: Balloon mean perimeter decreased from 33.5 cm ± 0.53 cm to 28.5 cm ± 0.46 cm (p < 0.0001). No significant differences were seen with the methylene blue group. Only 11 cases were found reported in the literature. CONCLUSIONS: Despite contaminating intragastric balloons with gastric aspirates, hyperinflation did not occur, and other factors may be in play to account for this phenomenon, when observed. Rates of hyperinflation remain under-reported in the literature. Further controlled experiments are needed.

BACKGROUND: Coronavirus disease-2019 (COVID-19) is a global pandemic. Obesity has been associated with increased disease severity in COVID-19, and obesity is strongly associated with hepatic steatosis (HS). However, how HS alters the natural history of COVID-19 is not well characterized, especially in Western populations. AIMS: To characterize the impact of HS on disease severity and liver injury in COVID-19. METHODS: We examined the association between HS and disease severity in a single-center cohort study of hospitalized COVID-19 patients at Michigan Medicine. HS was defined by either hepatic steatosis index > 36 (for Asians) or > 39 (for non-Asians) or liver imaging demonstrating steatosis > 30 days before onset of COVID-19. The primary predictor was HS. The primary outcomes were severity of cardiopulmonary disease, transaminitis, jaundice, and portal hypertensive complications. RESULTS: In a cohort of 342 patients, metabolic disease was highly prevalent including nearly 90% overweight. HS was associated with increased transaminitis and need for intubation, dialysis, and vasopressors. There was no association between HS and jaundice or portal hypertensive complications. In a sensitivity analysis including only patients with liver imaging > 30 days before onset of COVID-19, imaging evidence of hepatic steatosis remained associated with disease severity and risk of transaminitis. CONCLUSIONS: HS was associated with increased disease severity and transaminitis in COVID-19. HS may be relevant in predicting risk of complications related to COVID-19.

The aim of this cross-sectional study was to assess the knowledge about epilepsy and the attitudes toward people with epilepsy (PWE) and their predictors among university students in Jordan. A self-administered questionnaire was distributed in three of the largest public universities in Jordan, and a total of 500 questionnaires were collected from each university. The number of students who reported that they had heard or read about epilepsy was 1165 (77.6%), and their data were analyzed. A significant proportion of students thought that epilepsy could be caused by the evil spirit (31.5%) and the evil eye (28.1%) or that it could be a punishment from God (25.9%). Epilepsy's most commonly reported treatment methods were the Holy Quran (71.4%), medications (71.3%), and herbs (29.3%). The most common negative attitudes toward PWE were that the students would refuse to marry someone with epilepsy (50.5%) and that children with epilepsy must join schools for persons with disabilities (44.4%). Male students, students of humanities, and students with a low socioeconomic status tended to have more negative attitudes toward PWE. In conclusion, many students have misconceptions about the causes, treatment, and nature of epilepsy, and students have moderate negative attitudes toward PWE. Universities should have health promotion programs to increase awareness of their students about major public health problems such as epilepsy.

RESUMO
A 67-year-old man with a history of alcohol and hepatitis C-associated cirrhosis is diagnosed with incidental metastatic liver cancer during hospitalization for hepatic encephalopathy. He had 2 LI-RADS-3 (indeterminant) lesions on liver magnetic resonance imaging 3 months prior but had no history of hepatocellular carcinoma and was listed for liver transplant. During inpatient paracentesis, the ascites fluid was bloody, so the abdominal and pelvic computed tomography was performed showing a lytic lesion in the left posterior inferior pubic rami. Alpha fetoprotein was within normal limits. His liver was imaged on several occasions without definite evidence of malignancy. Bone biopsy revealed metastatic hepatocellular carcinoma. On return to baseline mental status, patient endorsed no bony pain.
RESUMO
Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition characterized by inflammation and eosinophilic accumulation of the esophagus, resulting in dysphagia and food impaction. While the exact etiology of EoE remains unclear, it is believed to be triggered by food allergens and dynamic environmental factors, resulting in various clinical manifestations, from inflammation to fibrosis. Although clinical presentation varies with age, the number of eosinophils in esophagogastroduodenal endoscopy remains the diagnostic gold standard. While diet elimination, proton pump inhibitors (PPIs), topical corticosteroids, and biological therapy are promising treatment options for EoE, there are insufficient data to determine the optimal therapeutic treatment approach. Combination therapies - the use of dietary therapies in conjunction with other treatment modalities, such as PPIs, topical corticosteroids, or biologic agents - have also emerged as a potential management strategy for EoE. In this systematic review, we attempt to highlight the recent advances in EoE therapies and provide updated guidance to their management. From 2017 to 2022, we conducted a comprehensive electronic search of PubMed (MEDLINE) using specific keywords related to our objective and eventually included a total of 44 articles.
RESUMO
Viral-induced pancreatitis has been well-defined; however, there are limited data regarding COVID-19 and pancreatitis. Most cases are commonly in conjunction with severe COVID-19 as well as lipase elevation. We describe a unique case of mild SARS-CoV-2 infection resulting in acute pancreatitis in the absence of lipase elevation. A 39-year-old patient with no medical history, presented with epigastric pain. Vital signs were unremarkable. Patient was positive for COVID-19. Liver function panel, calcium, triglyceride and lipase levels were all unremarkable. CT of the abdomen demonstrated acute pancreatitis without gallstones. Our case may indicate that pancreatic injury in SARS-CoV-2 infection is due to a direct impact on the pancreas by the virus, given the absence of lipase elevation and mild presentation. This case highlights the importance of suspecting pancreatitis in mild COVID-19 that present with atypical symptoms such as epigastric pain, even without lipase elevation.

BACKGROUND: Abdominal pain is a debilitating symptom affecting â¼80% of pancreatic cancer (PC) patients. Pancreatic duct (PD) decompression has been reported to alleviate this pain, although this practice has not been widely adopted. We aimed to evaluate the role, efficacy, and safety of endoscopic PD decompression for palliation of PC post-prandial obstructive-type pain. METHODS: A systematic review until 7 October 2020 was performed. Two independent reviewers selected studies, extracted data, and assessed the methodological quality. RESULTS: We identified 12 publications with a total of 192 patients with PC presenting with abdominal pain, in whom PD decompression was attempted, and was successful in 167 patients (mean age 62.5 years, 58.7% males). The use of plastic stents was reported in 159 patients (95.2%). All included studies reported partial or complete improvement in pain levels after PD stenting, with an improvement rate of 93% (95% confidence interval, 79%-100%). The mean duration of pain improvement was 94 ± 16 days. Endoscopic retrograde cholangiopancreatography (ERCP)-related adverse events (AEs) were post-sphincterotomy bleeding (1.8%), post-ERCP pancreatitis (0.6%), and hemosuccus pancreaticus (0.6%). AEs were not reported in two patients who underwent endoscopic ultrasound-guided PD decompression. In the 167 patients with technical success, the stent-migration and stent-occlusion rates were 3.6% and 3.0%, respectively. No AE-related mortality was reported. The methodological quality assessment showed the majority of the studies having low or unclear quality. CONCLUSION: In this exploratory analysis, endoscopic PD drainage may be an effective and safe option in selected patients for the management of obstructive-type PC pain. However, a randomized-controlled trial is needed to delineate the role of this invasive practice.
RESUMO
Introduction Obesity-related gastrointestinal disorders including nonalcoholic fatty liver disease (NAFLD) and gastroesophageal reflux disease (GERD) are more frequent and usually present earlier than type 2 diabetes mellitus (T2DM) and cardiovascular disorders. This provides an opportunity for the gastroenterologist to intervene early with an effective weight-loss therapy. We evaluated the outcomes of a multifaceted, community-based gastroenterologist-supervised weight management program compared with patient-directed weight-loss efforts after physician advice. The program is aimed at achieving a 10% total body weight (TBW) loss at three months, a known determinant for NAFLD regression. Methods This is a retrospective pre- and post-intervention study of NAFLD patients, who participated in a medically supervised weight management program in the period between May 2017 and May 2019. The program is comprised of a very-low-calorie (800 kcal/day) meal replacement diet, a recommended medical fitness program, and weekly behavioral support groups. Patients are followed on monthly basis and slowly transitioned to a whole food plant-based or Mediterranean diet after three months of participation. Patients' weight trends driven by self-directed efforts to lose weight after physician advice were collected based on historical data up to two years prior to program participation. The primary outcome was defined as percentage TBW loss at three months under medical supervision (post-intervention) compared with patient-directed weight-loss efforts (pre-intervention). The secondary outcomes included percentage TBW loss in relation to behavioral support group attendance and improvement in GERD and T2DM disease status after program participation. Linear mixed and linear regression models were used to assess for a statistically significant difference in percentage TBW loss. Statistical significance was defined as p < 0.05. Results A total of 114 NAFLD patients (mean age 55 years, mean BMI 39 kg/m2, 77 females, and 37 males) completed at least three months of follow-up and were included in the study. Of those, 89 patients had a documented three-month office visit. At three months, 65% of patients had lost at least 10% of their TBW. Percentage TBW loss under medical supervision was noted to be significantly higher and occurred at a faster rate over three months when compared with patient-directed efforts after physician advice (p < 0.001). Patients who attended the behavioral support groups ≥ 50% of the time had a 3% higher TBW loss at three months compared with patients who attended <50% of the time (p = 0.006). Approximately, 52% of patients with GERD and 38% of patients with T2DM had symptoms improvement and/or medication reduction at their three-month follow-up visit. Conclusion A multifaceted, community-based, gastroenterologist supervised weight management program is effective in achieving a clinically significant TBW loss of at least 10% within three months of participation. This weight loss was greater and occurred at a faster rate when compared with patient-directed efforts. Additionally, improvement in GERD and T2DM disease status was noted in 52% and 38% of patients with these conditions, respectively. Further community-based studies of a larger scale are needed to determine the sustainability of this weight loss over one year.
RESUMO
Introduction Annually, 500,000 episodes of alcohol withdrawal syndrome (AWS) are severe enough to require clinical attention. A symptom-triggered lorazepam regimen remains the standard of care for the management of hospitalized AWS patients. However, phenobarbital has also been shown to be an effective adjunctive therapy for severe AWS, reducing benzodiazepine use in the emergency department (ED) and the intensive care unit (ICU). The purpose of this study is to compare hospital length of stay (LOS) for AWS patients using phenobarbital-based versus lorazepam-based treatment protocols as monotherapy for management of AWS on general medical units. Methods This is a retrospective cohort study over a two-year period (March, 2016 to March, 2018), conducted at three hospitals within the St. Joseph Mercy Health System. We included 606 patients with a primary diagnosis of AWS or alcohol intoxication who met our inclusion criteria (543 in the lorazepam cohort and 63 in the phenobarbital cohort). Adjusted comparisons were done using propensity scoring methods. Hospital LOS was set as the primary outcome. Secondary outcomes included all-cause 30-day readmission, alcohol-related 30-day readmission, 30-day ED visits after discharge, and need for ICU transfer during hospital stay. Results Patients who received phenobarbital had a statistically significant shorter hospital LOS as compared to patients who received lorazepam (2.8 versus 3.6 days, P < 0.001). Furthermore, the phenobarbital treatment group had statistically significant lower rates of all-cause 30-day readmission (11.11% versus 14.18%, P = 0.020) and 30-day ED visits after discharge (11.11% versus 18.6%, P = 0.015). No statistical significance was detected for alcohol-related 30-day readmission and the need for ICU transfer between the treatment groups. Conclusion This study suggests that phenobarbital may be a reasonable alternative to lorazepam in the management of AWS patients admitted to general medical units. Larger scale, well-executed, and adequately powered prospective studies and randomized controlled trials are needed to corroborate these findings.
RESUMO
Colorectal cancer (CRC) is the most common tumor type in both sexes combined in Western countries. Although screening programs, including the implementation of fecal occult blood test and colonoscopy, might reduce mortality by removing precursor lesions and making the diagnosis at an earlier stage. Unfortunately, ~25% to 40% will develop a tumor recurrence despite a curative operation. It is well-known that most recurrences occur within five years. There are a lot of solid guidelines for recurrence surveillance. We present a case of colon adenocarcinoma that underwent surgical resection of the descending colon with close recurrence surveillance follow-ups that showed normal carcinoembryonic antigen (CEA) for 12 years and then presented again with blood in stool and was found to have recurrent colon adenocarcinoma.
RESUMO
Adenomas or adenocarcinomas located within a colonic diverticulum are considered a rare phenomenon that has been described in the literature. These lesions are technically difficult to manage endoscopically and usually require surgical intervention for removal. There is also an increased risk of perforation upon endoscopic resection owing to the lack of a muscular layer within the diverticulum. We report a case and include a literature review to evaluate different endoscopic techniques and propose the most effective for management of adenomas within a diverticulum. This technique is potentially comprised of employing a combined approach using a suction banding device, an over-the-scope clip (OTSC; Ovesco Endoscopy AG, Tübingen, Germany) , and hyperthemic snare to successfully remove the polyp, ensure tissue retrieval, and reduce risk of iatrogenic colonic perforation.
RESUMO
Background and study aims Endoscopic resection is recommended as initial treatment for early-stage gastric and duodenal neuroendocrine tumors (G-NETs and D-NETs). However, it can cause serious adverse events. We aimed to evaluate the efficacy and safety of the band and slough (BAS) technique as a novel and less aggressive endoscopic therapy for management of such tumors. Four patients, three diagnosed with <â10-mm D-NET and one with 10-mm type I G-NET, were treated with the BAS technique without endoscopic resection. Initial follow-up endoscopy at 3 months was done to assess for residual tumor. Subsequent endoscopic surveillance was performed. After one session of banding, all patients achieved complete remission at 3-month follow-up. No tumor recurrence was detected on repeat biopsy at 12-month surveillance endoscopy. None of the patients developed any adverse events including bleeding or perforation. The BAS technique may prove to be a safe and effective endoscopic therapy for diminutive, non-metastatic type 1 G-NETs and D-NETs. Studies of larger scale and longer follow-up periods are needed to corroborate these findings.
