RESUMO
BACKGROUND: Flexible bronchoscopy (FB) often involves sedation, with the choice left to the bronchoscopist's discretion. Prior research on sedation in gastroscopic endoscopies yields conflicting information regarding the preferred method for FB. This study compares patient comfort levels during bronchoscopy with mindful sedation using fentanyl, nalbuphine, and midazolam versus monitored anesthesia care (MAC) using propofol, midazolam, and ketamine. METHODS: This prospective observational study assessed 83 patients undergoing bronchoscopy under either conscious sedation (CS) (n=40) or MAC (n=43). Patient comfort, sedation levels, emotional state, recovery time, safety, and the impact of smoking history and comorbidities were evaluated. Data collection included direct patient questioning and observation using the Modified Observed Assessment of Alertness and Sedation (MOAA/S) form. RESULTS: Comfort levels were similar between groups, with mean scores of 3.6±0.89 for CS and 3.3±0.54 for MAC. MAC induced deeper sedation (mean scores: 4.37±0.66 vs. 3.8±0.98). Recovery time and complications were comparable. Emotional states and medical history did not significantly differ between groups. CONCLUSION: CS is not inferior to MAC for bronchoscopy, providing comparable comfort and safety with less intense sedation and lower cost. These findings support the use of CS for bronchoscopy procedures, offering a cost-effective alternative without compromising patient comfort or safety.
RESUMO
Evaluating educational climate (EC) is imperative for ensuring postgraduate trainees' competencies and quality in residency training programs. This study assessed the EC experiences of pathology postgraduate residents (PGRs) during their postgraduate training in pathology residency programs-a cross-sectional study design assigned EC scores in the pathology residency program at a prestigious institution in Islamabad, which were measured using the Dutch Residency Educational Climate Test (D-RECT) questionnaire. Scores from the D-RECT were employed to conduct descriptive statistics and comparison of means across groups to evaluate EC scores by years of training and compared to assess where the differences were located. Among FCPS-II pathology residents, most of whom were females (94.4%), the mean age was 28.11±2.91 years. A mean positive score was observed among all pathology residents (M≥3.6) for all D-RECT subscales except for the feedback subscale: the average score for feedback was below the average mean score of 3.6 (M = 3.19). A significant difference p = 0.016 was observed in EC scores across different groups through the Analysis of Variances (ANOVA) test. The most significant difference was between less than two and greater than two groups p = 0.027, followed by the difference between equal to two groups and greater than two groups p = 0.052. Overall, positive scores for EC in the pathology residency program were observed. Thus, targeted interventions are needed to increase feedback scores and address observed differences in EC scores by years of training.

Background and objectives: Acute-on-chronic liver failure (ACLF) is associated with high short-term mortality without liver transplantation (LT). The selection criteria for LT in these patients are not well defined. The objective of this study was to determine factors associated with post-transplant survival in ACLF. Methods: This was a single-center retrospective study of patients who underwent living donor liver transplantation (LDLT) for ACLF between 2012 and 2022. Out of 1093 transplants, 110 patients had underlying ACLF, based on the European Association for the Study of the Liver-Chronic Liver Failure Consortium (EASL-CLIF) criteria. We looked at factors associated with 1-year posttransplant survival. Results: The median model for end-stage liver disease (MELD) score was 33.5 (31-38), and the 1-year posttransplant survival was 72%. Six risk factors were associated with posttransplant survival, namely, body mass index > 30 kg/m2 [HR, 4.4; 95% CI, 1.8-10.7], platelet count < 66,000/µl [HR, 2.91; CI,1.2-6.6], poor response to medical treatment [HR, 2.6; CI, 1.1-5.7], drug-resistant bacterial or fungal cultures [HR, 4.2; CI, 1.4-12.4], serum creatinine > 2.5 mg/dl [HR, 3.4; CI, 1.5-7.7], and graft-to-recipient weight ratio < 0.7 [HR, 4.8; CI, 1.4-16.3]. The 1-year post-transplant survival was 84% in patients with 0-2 risk factors (n = 89) and was 6% with 3 risk factors (n = 15) (P < 0.001). For 1-year posttransplant survival, the area under curve (AUC) for the current model was 0.8 (0.69-0.9). The AUC for CLIF-ACLF, Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA), and EASL-CLIF ACLF grades was < 0.5. Conclusion: In LT for ACLF, acceptable survival can be achieved when less than three high-risk factors are present.
RESUMO
BACKGROUNDS/AIMS: Metastatic lesions of the pancreas (PMET) account for 1%-5% of all malignant solid pancreatic lesions (SPL). In this study we evaluated the utility of endoscopic ultrasonography with fine needle aspiration (EUS-FNA) in diagnosing PMET. METHODS: Patients who underwent EUS-FNA at a community referral center between 2011-2017 for SPL were identified. Clinical, radiologic, and EUS-FNA features of those with PMET were compared to those with primary solid tumors of the pancreas: pancreatic adenocarcinoma (PDAC) and neuroendocrine tumors (PNET). RESULTS: A total of 191 patients were diagnosed with solid pancreatic malignancy using EUS-FNA: 156 PDAC, 27 PNET, and eight (4.2%) had PMET. Patients with PMET were less likely to have abdominal pain (25.0% vs. 76.3% vs. 48.2%; p < 0.01) or obstructive jaundice (37.5% vs. 58.3% vs. 0%; p < 0.01) compared to PDAC and PNET. Those with PMET were more likely to have mass lesions with/without biliary or pancreatic ductal dilatations (100% vs. 86.5% vs. 85.2%; p < 0.01) and lower CA19-9 (82.5 ± 43.21 U/mL vs. 4,639.30 ± 11,489.68 U/mL vs. 10.50 ± 10.89 U/mL; p < 0.01) compared to PDAC and PNET. Endosonographic features were similar among all groups. Seven (87.5%) patients with PMET had a personal history of malignancy prior to PMET diagnosis. The primary malignancy was renal cell carcinoma in five PMET. CONCLUSIONS: PMET are exceedingly rare, comprising less than 5% of SLP. Patients with PMET are less likely to present with symptoms and mostly identified by surveillance imaging for the primary malignancy.
RESUMO
Granular cell tumors (GCT) are benign, submucosal tumors derived from neural or Schwann cells. They are commonly found in the oral cavity, skin, breast and tongue. Less commonly, they can also occur in the gastrointestinal tract, usually in the esophagus. We describe two cases of esophageal GCT which were discovered by upper endoscopy (EGD). Case one underwent endoscopic ultrasound (EUS) guided fine needle aspiration and biopsy and case two underwent biopsy of a submucosal nodule. Both biopsies were histologically diagnosed as GCT with supportive S100 positive immunostaining. GCTs are an important diagnosis for physicians to consider in their differential of esophageal nodule or lesion. Though benign, they may rarely show malignant transformation. Therefore, it is essential to have surveillance with EGD/EUS every two to three years if they are not surgically resected.

BACKGROUND: We aimed to study the effect of socioeconomic differences and molecular characteristics on survival in patients with young-onset pancreatic neuroendocrine tumors (YOPNET) and typical-onset PNET (TOPNET). METHODS: We identified the patients with YOPNET (<50 years) and TOPNET (≥50 years) who underwent definitive surgery diagnosed between 2004 and 2016 using the National Cancer Database. We evaluated overall survival (OS) using the Kaplan-Meier and Cox regression methods before and after propensity score matching. A publicly available genomic dataset was used to compare mutation frequencies among the two groups. RESULTS: A total of 6259 patients with PNET were included, of which 27% were YOPNET. Patients with YOPNET were more likely to be Black, Hispanic, female, and have private insurance versus patients with TOPNET (all p < 0.001). Patients with YOPNET had a lower comorbidity score, but higher stage and tumor size (all p < 0.001). YOPNET was associated with a greater improved OS than TOPNET before and after propensity score matching (p < 0.001). On multivariable analysis, this survival difference persisted for YOPNET as an independent prognostic factor (unmatched p = 0.008; matched p = 0.01). For genomic analysis, patients with YOPNET had a lower rate of multiple endocrine neoplasia type-1 (MEN-1) mutation than patients with TOPNET (26% vs. 56%, p < 0.001). CONCLUSIONS: YOPNET represents a disease with distinct clinical features. Patients with YOPNET who underwent definitive surgery had better OS than patients with TOPNET despite having higher stage and tumor size. YOPNET also had lower rate of MEN-1 mutation.
RESUMO
Extramedullary myeloid sarcomas are extramedullary tumors of immature myeloid cells, often associated with acute myeloid leukemia (AML), chronic myeloid leukemia (CML), or other myeloproliferative diseases. They are usually found in connective/soft tissues, skin, breast and gastrointestinal system. Pancreas is an uncommon site to be involved. We present a case of pancreatic myeloid sarcoma presenting with symptoms of acute pancreatitis including epigastric pain associated with nausea and vomiting, with imaging findings (abdominal CT) suggestive of pancreatic carcinoma, both presenting as hypoattenuating mass. It is important to consider myeloid sarcoma as a differential for pancreatic mass, especially given the history of AML as in our patient, which would lead to timely diagnosis and initiation of chemotherapy.

BACKGROUND: The mainstay for the definitive diagnosis of pancreatic lesions is endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). However, there is evidence that EUS-FNA has low sensitivity in the setting of chronic pancreatitis (CP). This single-center retrospective study aimed to compare and analyze the diagnostic yield of EUS-FNA for solid pancreatic lesions in the presence and absence of CP, and to further investigate strategies for overcoming the low diagnostic yield in the setting of CP. METHODS: This study identified patients who underwent EUS-FNA at Sanford USD Medical Center (SD, USA) for a solid pancreatic lesion between July 15, 2011, and November 30, 2017. Data on demographics, clinical features, cross-sectional imaging findings, EUS findings, cytology/pathology, and clinical follow up were collected. RESULTS: The final diagnosis was adenocarcinoma in 156 patients (67%), neuroendocrine tumor in 27 (12%), lymphoma in 6 (3%), metastatic malignancy in 8 (4%), and benign etiologies in 35 (15%). CP was identified in 44/234 (19%) patients. The overall diagnostic sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for EUS-FNA were 92.9%, 97.1%, 99.5%, 70.8%, and 93.5%, respectively. The sensitivity (80% vs. 95%, P=0.020) and accuracy (86% vs. 95%, P=0.043) were significantly lower in patients with CP compared to those without CP. CONCLUSION: CP can significantly affect the EUS-FNA diagnostic yield of solid pancreatic neoplasms. A high index of clinical suspicion is required in these cases to make a definitive diagnosis.

A 43-year-old woman, with an unremarkable past medical history, presented with a three-week history of generalized itching, jaundice, and abdominal pain. Initial workup showed amorphous, regionally invasive, and obstructing soft tissue mass in the region of the hepatic hilum. The middle third of the main bile duct was subsequently found to harbor a polypoid mass on endoscopic retrograde cholangiopancreatograph. Biopsy revealed nests of neoplastic cells that was subsequently identified as well-differentiated neuroendocrine tumor. A search for a possible primary neuroendocrine tumor was performed and included imaging of the chest, abdomen, and pelvis, a colonoscopy, capsule endoscopy, and an octreotide scan; however, no primary tumor outside of the liver was identified. Surgical debulking was performed, during which intraoperative exploration and ultrasound failed to reveal any extra-hepatic tumor sanctuaries. A few months later, patient underwent endoscopic ultrasound (EUS) for evaluation of recurrent abdominal pain which revealed a small lesion in the pancreas. It was unclear, however, whether it was primary or a metastatic lesion. This case represents a diagnostic challenge and emphasizes the potential utility of EUS in the preoperative work up for any presumable primary hepatobiliary neuroendocrine tumor.

BACKGROUND: Pancreatic cancer is the fourth leading cause of cancer-related mortality in the United States. Descriptive epidemiology of pancreatic cancer in South Dakota has not been studied before. MATERIALS AND METHODS: All cases of pancreatic cancer reported to the SD Cancer Registry between January 2005 and December 2014 were included in the study. Variables collected included demographics, geographical location including county of residence and zip codes, date of diagnosis, date of last contact or follow-up, size and location of the tumor, grade of the tumor, diagnostic modality as well as therapeutic interventions. Log rank test was used to compare survival curves. Kaplan-Meier product limit estimates were provided. Data was analyzed using SAS 9.1.4 software. RESULTS: One thousand sixty-four cases of pancreatic cancer were reported. Median age was 73 years. Cumulative age-adjusted incidence rate for pancreatic cancer for 2005-2014 was 11.1. Cumulative age-adjusted mortality rate for pancreatic cancer for 2005-2014 was 10.2. Almost half of these patients had distant metastasis at the time of presentation (n = 536; 50.4%). Overall, median survival was 5 months. Median survival for patients under the age of 60 years was 9.5 months as opposed to median survival for patients 60 years or older which was 3.9 months. Median survival of patients with well-differentiated, moderately differentiated, and poorly differentiated tumors, was 20.8 months, 8.2 months and 6.3 months respectively (p value = 0.0017). CONCLUSION: Incidence of pancreatic cancer in South Dakota is similar to the national trends in the United States. Age at presentation, location of tumor in pancreas, and biological behavior of tumor were all predictors of survival in patients with pancreatic cancer.

Many cases of appendicitis can be associated with appendicoliths. These may sometimes be lost during appendectomies and may be lodged in the body. Most of these cases lead to recurrent abscess formation, and these appendicoliths invariably need removal. Typically, this used to be done as an open surgery or laparoscopically. Here we describe the case of a transcutaneous removal of an appendicolith that was lodged between the liver and diaphragm that led to recurrent perihepatic abscess formation in a 24-year-old otherwise healthy man. The patient made a successful recovery without any recurrence. A transcutaneous approach to remove a retained appendicolith may be a feasible, a safe and an easy method to extract appendicoliths that are accessible for transcutaneous removal.

BACKGROUND: To review all the reported literature on acute esophageal necrosis. RESEARCH METHODS: Databases were searched using the special Medical Subject Heading (MeSH) terms. All the available reported cases of acute esophageal necrosis were analyzed. RESULTS: A total of 154 cases were identified and 130 cases were analyzed. The mean age of presentation was 61 years, and 70% of cases were males. The most common presenting symptoms were hematemesis in 66%, shock in 36%, melena in 33%, abdominal or substernal pain in 28%. The most common comorbidities reported were diabetes in 38%, hypertension in 37%, alcohol abuse in 25%, and chronic kidney disease in 16%. On upper endoscopy, 51% had a distal disease, 36% had pan esophageal, and only 2% had a proximal disease. 84% of patients were treated with IV Proton Pump Inhibitors, 22% received transfusions, 23% got antibiotics for underlying sepsis, 14% also received sucralfate, and 4% required surgery for treatment. The mortality rate was 32%, while perforation was reported in 5% and stricture formation reported in 9% of patients. CONCLUSIONS: Patients with acute esophageal necrosis can have a favorable outcome if treated appropriately.

Cystic pancreatic neuroendocrine tumors represent around 13% of all neuroendocrine tumors (Hurtado-Pardo 2017). There has been an increase in the incidence of cases due to improvement in imaging modalities. This is a case of a 68-year-old male with the incidental finding of a pancreatic cyst on CT. Initial Endoscopic Ultrasound with Fine Needle Aspiration (EUS-FNA) showed sonographic and cytology features suggestive of a pancreatic pseudocyst. However the cyst persisted with no change in size after aspiration leading to a follow-up EUS- FNA, which was combined with needle based confocal laser endomicroscopy (nCLE). The nCLE features were consistent with a cystic pancreatic neuroendocrine tumor, which was later confirmed on histology after surgical resection.
RESUMO
BACKGROUND AND STUDY AIMS: Boerhaave's syndrome (BS) is a life-threatening condition with morbidity and mortality rates as high as 50â% in some reports. Until recently, surgical intervention has been the mainstay of management plans. With advances in therapeutic endoscopy, however, there has been increasing interest in non-surgical options including endoscopic esophageal stenting. PATIENTS AND METHODS: We reviewed the medical records of all patients diagnosed with BS and managed with endoscopic interventions between November 2011 and November 2016. The following variables were collected: patient demographics, clinical presentations, locations of esophageal perforation, primary interventions, complications, and outcomes. RESULTS: Six patients were found to be diagnosed with BS during the study period. The median age at presentation was 55. There were 4 males and 2 females. The most common site of perforation was in the distal esophagus. The most common presenting symptom was chest pain (67â%) following an episode of vomiting or retching. Four patients (66.7â%) developed septic shock. Endoscopic treatment with a fully covered esophageal stent was the primary intervention in all patients (100â%). Interventional radiology was consulted in all cases for fluid drainage and chest tube placements. Clinical resolution of the BS was achieved in all patients (100â%) without any subsequent surgical interventions. There were no deaths within the study group, and the average follow-up duration was 2 years. CONCLUSION: Endoscopic treatment seems to be an effective management strategy in patients with BS. We also noted satisfactory results in patients presenting with sepsis, presumably due to urgent, interventional radiology-guided fluid drainage.
RESUMO
INTRODUCTION: Pre-operative evaluation of biliary strictures remains challenging. The dilemma that exists is how to balance the risk of failing to detect malignancy and the potential morbidity caused by unnecessary surgery in patients with benign etiologies. With emerging novel diagnostic modalities, this study aims to assess the efficacy of diagnostic techniques and facilitate a clinical approach to indeterminate biliary strictures. Areas covered: Conventional imaging modalities are crucial in identifying the location of a stricture and are helpful for choosing further diagnostic modalities. Utilization of endoscopic techniques, including endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS), is key in establishing a diagnosis. The emergence of novel diagnostic modalities, such as fluorescence in-situ hybridization (FISH), peroral cholangioscopy (POC), intraductal endoscopic ultrasound (IDUS) and confocal laser endomicroscopy (CLE), enhance the diagnostic yield in the evaluation of indeterminate biliary strictures. Expert commentary: More reliable and validated visual criteria for differentiating malignancy from benign biliary conditions, utilizing advanced imaging modalities such as POC and CLE, need to be established. It is of significance to further evaluate these novel diagnostic modalities through ongoing trials and to develop a diagnostic algorithm that reconciles cost-effectiveness with diagnostic accuracy.

Oriental cholangiohepatitis (OCH) is a disease characterized by intrabiliary pigment stone formation, resulting in recurrent bouts of cholangitis. OCH is found mostly in Southeast Asia but it is occasionally recognized in Western societies. OCH etiology is largely unknown. We report our experience with a patient who presented with acute cholecystitis. Following laparoscopic cholecystectomy, she developed acute cholangitis due to multiple biliary tree stones. She underwent ERCP to clear the stones from common bile duct. For the intrahepatic stones, she underwent novel hybrid percutaneous endoscopic technique. The procedure resulted in complete clearance of biliary tree stones and resolution of her symptoms. The aim of this case is to increase awareness of this disease when patients from endemic areas present with biliary stones.
