ABSTRACT
Introduction: The need for standardised education on tracheostomy care is well recognised.1 Staff frequently report a lack of confidence in caring for those with tracheostomies, as well as the management of adverse events as they occur.2 Over the past decade, healthcare providers have developed strategies to educate staff, however, the covid-19 pandemic has severely hampered the ability to provide this necessary training due to restrictions on access to training rooms, the need for social distancing and the significant clinical demands placed on both trainers and trainees.3 The potential for immersive technologies to augment healthcare training is gaining interest exponentially.4 However, its effectiveness is yet to be clearly understood and as such it is not yet common within healthcare education.5 Based on the above, we aimed to explore the potential of these immersive technologies to overcome the current challenges of tracheostomy education, and to develop future strategies to use immersive technology in healthcare education. Method(s): We received a 400,000 grant from Cardiff Capital Region (CCR) to undertake a rapid innovation project overseen by the SBRI centre of excellence. The project consisted of 3 main phases: 1) feasibility;2) development;and 3) testing. The project was officially launched in April 2021 and lasted 12 months. Project governance was provided via the SBRI for clinical excellence, a project board with representation from Welsh Government, Cardiff University and Cardiff and Vale UHB, and a project team with clinical expertise in both the delivery of tracheostomy education and the provision of simulation training in healthcare. Result(s): Phase 1: During phase one 4 industries were successful and received up to 30,000 to explore the feasibility of immersive technology to support tracheostomy education. The industries were Rescape, TruCorp, Aspire2Be and Nudge Reality. During the feasibility phase all industries focused on the emergency management process utilising existing NHS Wales tracheostomy education resources and the national tracheostomy safety programme. Phase 2: For phase 2, Rescape and Nudge Reality were chosen to develop the technology. These industries continued to work in conjunction with the project team to capture the core elements of tracheostomy care, including multi-user emergency management scenarios. Additional content was also added for bronchoscopy and insertion of intercostal drains. Phase 3: Testing of both solutions was undertaken over an 8-week period, across 6 Health Boards in NHS Wales. The results of the testing will be analysed and available for presentation in due course. Provision findings demonstrate good face and content validity with high levels of user satisfaction. Discussion / Conclusion(s): The provision of essential tracheostomy education has been severely affected by the covid-19 pandemic. Evolving immersive technologies have the potential to overcome these challenges and improve the effectiveness and efficiency of education packages in tracheostomy care and wider. Through this CCR grant, in conjunction with industry, we have developed two solutions with the potential for widescale procurement and future research on the use of immersive technologies within healthcare.
ABSTRACT
We retrospectively report a case of rapid exchange of a percutaneous radiologic gastrostomy tube (balloon-occluded type catheter) via off-label use of a pigtail catheter for nutrition supply during a very early episode of coronavirus disease 2019 (COVID-19) in an outpatient clinic. This case demonstrates that minimally invasive percutaneous procedures might be provided safely and effectively under appropriate precautions for preventing COVID-19 transmission during the pandemic.Copyright © 2023, Society of Gastrointestinal Intervention.
ABSTRACT
Introduction: Spontaneous pneumothorax is a rare complication of coronavirus disease 2019 (COVID-19), primarily reported in adults. Pediatric cases with bilateral pneumothorax are much less reported. Case Presentation: We presented the case of a five-year-old previously healthy boy who developed persistent fever, abdominal pain, generalized maculopapular rash, and dyspnea before admission. His chest computed tomography (CT) showed a viral involvement pattern of pneumonia suggestive of COVID-19. Subsequently, he was confirmed with multisystem inflammatory syndrome in children (MIS-C). While he responded well to the therapies, on the fifth day of admission, he developed respiratory distress again. A chest roentgenogram showed bilateral spontaneous pneumothorax. Bilateral chest tubes were inserted, and his condition improved sig-nificantly after five days of admission to the intensive care unit. Two weeks later, he was discharged in good condition. Conclusion(s): Children with MIS-C associated with COVID-19 may develop primary spontaneous pneumothorax. Owing to the clinical picture overlapping with MIS-C associated with COVID-19, the timely diagnosis of pneumothorax may be challenging in such patients.Copyright © 2022, Author(s).
ABSTRACT
Introduction: The COVID-19 pandemic necessitated proliferation of telesimulation. This pedagogy may be useful in rural areas to increase procedural adoption and reduce healthcare disparities. Our aim was to determine the current status of surgical simulation education to retool rural practicing Urologists. Method(s): Literature search was performed with a trained librarian for PubMed, EMBASE and Web of Science. Title/ screening were performed to include all studies of surgical simulation involving rural surgical learners to identify simulation education opportunities for practicing rural Urologists. Data was then extracted: simulation event, skills focus, MERSQI score, type/number of learners, learner assessment and event evaluation. Result(s): Seven manuscripts met inclusion criteria. Most were published 2019-2020 and were cross sectional (5/7, 71%). Mean adjusted MERSQI score was 13 (range 6-15.5). A wide range of surgical skills were taught (incl. laparoscopy, cricothyroidotomy, chest tube insertion, damage control laparotomy), but no Urological surgical skills. Two articles described mobile simulation units for rural areas. A total of 232 learners were identified including 69 medical students. One fifth of rural learners were non-medical or non-physicians. Only one study involved faculty, who were general surgeons. Conclusion(s): Telesimulation education for practicing Urologists in rural areas is lacking. Current in-operating room telementoring for rural Urologists requires surgeons to travel and perform their first cases utilizing this new technique on patients. Telesimulation to teach Urological skills in rural areas of the US may increase dissemination of techniques with no patient risk and has significant potential to redress current healthcare disparities.
ABSTRACT
Objective: Acute respiratory tract infections are one of the leading causes of morbidity and mortality in children. Although human bocavirus (HBoV) infections are not as common as other seasonal respiratory viruses, children who are infected with HBoV are more likely to suffer from a variety of respiratory conditions, including the common cold, acute otitis media, asthma exacerbations, bronchiolitis pneumonia, some of the affected children require pediatric intensive care unit stay. Here, we aimed to evaluate pediatric bocavirus (HBoV) cases presenting with severe respiratory tract symptoms during the coronavirus disease 2019 (COVID-19) pandemic. Method(s): This retrospective study evaluated the medical records of children diagnosed with respiratory infections, followed up at the Faculty of Medicine, Eskisehir Osmangazi University between September 2021 and March 2022. In this study, patients with HBoV identified using nasopharyngeal polymerase chain reaction (PCR) were considered positive. Cases were analyzed retrospectively for their clinical characteristics. Result(s): This study included 54 children (29 girls and 25 boys) with HBoV in nasopharyngeal PCR samples. The cases ranged in age from 1 month to 72 months (median 25 months). At the time of presentation, cough, fever, and respiratory distress were the most prevalent symptoms. Hyperinflation (48%), pneumonic consolidation (42%), and pneumothorax-pneumomediastinum (7%) were observed on the chest X-ray;54% of the children required intensive care unit stay. The median length of hospitalization was 6 days. Bacterial coinfection was detected in 7 (17%) children, while HBoV and other viruses were present in 20 (37%) children;57% of children received supplemental oxygen by mask, 24% high-flow nasal oxygen, 7% continuous positive airway pressure, and 9% invasive mechanical ventilation support. Antibiotics were given to 34 (63%) cases, and systemic steroid treatment was given to 41 (76%) cases. Chest tubes were inserted in three out of the four cases with pneumothorax-pneumomediastinum. All patients were recovered and were discharged from the hospital. Conclusion(s): The COVID-19 pandemic changed the epidemiology of seasonal respiratory viruses and the clinical course of the diseases. Although it usually causes mild symptoms, severe respiratory symptoms can lead to life-threatening illnesses requiring intensive care admission.Copyright © 2023. The Author(s).
ABSTRACT
Objectives: Reviewing current literature and case reports of patients placed on Venous-Venous ECMO support for HIV and AIDS, with confection with Pneumocystis pneumonia and covid-19 pneumonia. The use of extracorporeal membrane oxygenation (ECMO) in patients who have acute respiratory distress syndrome has been shown to have very good outcomes. However, there is limited data to support the initiation of ECMO in patients who have human immunodeficiency virus infection with or without acquired immune deficiency syndrome. Method(s): We present a unique and challenging case of a 30 year old male, with no known past medical history, unvaccinated against covid-19, who presented with one week of progressive shortness of breath. On admission he was found with moderate bilateral infiltrates and was diagnosed with covid-19 pneumonia. Despite appropriate medical therapy, patient developed worsening hypoxic respiratory failure. Found to have elevated (1- 3)-7beta;-d-glucan and tested positive for HIV. CD4 count 11, HIV viral load 70,000. The patient remained severely hypoxemic despite mechanical ventilation, sedation, paralytics and proning. Venous venous extracorporeal membrane oxygenation was initiated. Considering his non improvement with variety of antivirals and antibiotics and with elevated (1-3)-7beta;-d-glucan in the setting of AIDS he was treated for presumed Pneumocystis pneumonia. The patient tolerated proning while on VV ECMO and his course was complicated with bilateral pneumothorax necessitating chest tube placement. Result(s): The patient successfully completed 64 days on VV ECMO, where he was treated for PCP pneumonia, covid pneumonia, CMV viremia and tolerated initiation of anti-retroviral therapy. Patient was successfully decannulated, and ultimately discharged from the hospital. Conclusion(s): VV-ECMO can be a beneficial intervention with successful outcomes in severely immunocomprimised patients with AIDS. This case highlights the importance of minimizing sedation and early mobilization on ECMO support. (Figure Presented).
ABSTRACT
As part of Mumbai Coastal Road Project-the connection between Nariman Point and Bandra Worli, a total length of 10.58 km-Package IV (MCRP4) includes submarine twin tube tunnels. Current Package's total length is 4,480 m, of which 2,008 m are excavated by means of one slurry shield and supported/lined by precast segments. Each tube will accommodate a three-lane carriageway, for an internal diameter of 11 m and an excavation diameter 12.19 m. To enable the launching and receiving of the TBM, two shafts were constructed at North end and South end of the package. The reception shaft is 42m long and 30m wide with a depth of 26m below the ground formation level at +3.0 msl. The intention was to disassemble the TBM after the first drive to reassemble and relaunch it from the original shaft – the "launch-ing shaft”. However, due to logistical constraints, given the project location in a dense urban setting, and due to time delays, because of stoppage of works during Covid lockdown, the Contractor of the project decided to relaunch the TBM from the reception shaft itself by rotating the TBM and save approx. 60-75 days. Due to this dynamic need of the project, reception shaft was repurposed for relaunching with additional ancillary structures (like Heavy weight modular gantry crane foundations, TBM reaction frame, Slurry treatment plant on surface etc.,) in and around the shaft which weren't foreseen during the excavation of shaft. This paper discusses design aspects with special focus on challenges which were needed for this repurposing of shaft. © 2023 The Author(s).
ABSTRACT
COVID-19 causes acute respiratory failure syndrome (SIRA), leading patients to require intubation in the intensive care unit (ICU). A common complication of this ventilatory support is dysphagia, which has a prevalence of up to 30%.This work aims to describe rehabilitation methods in patients with coronavirus infection based on levels of evidence according to the GRADE System, so a systematic review of the literature was carried out. The selected articles were divided into the following subtopics: diagnosis of dysphagia and rehabilitation in COVID patients. The gold standard for the diagnosis of dysphagia is the videofluoroscopic swallowing study (VFS). Fiberoptic Evaluation of Swallowing Assessment (FEES) has high sensitivity and specificity, although they have the disjunction of an aerosol-generating procedure (AGP);however, in a pandemic situation, the study of choice in the literature is VF. Once the diagnosis is made, it is necessary to initiate rehabilitation as soon as possible, even from hospitalization in patients who have hemodynamic stability to prevent long-term effects and promote normal swallowing even before discharge. In patients with COVID-19 infection dysphagia, the risk-benefit of assessment tools and therapy used for diagnosis should be decided to help to maintain social distancing. It becomes imperative to carry out clinical studies with high levels of evidence that allow us to generate Clinical Practice Guides for the benefit of our patients.Copyright © 2021 Sociedad Medica del Hospital General de Mexico.

ABSTRACT
Background: Improving basic infection control (IC) practices, diagnostics and anti-microbial stewardship (AMS) are key tools to handle antimicrobial resistance (AMR). Material(s) and Method(s): This is a retrospective study done over 6 years (2016-2021) in an oncology centre in North India with many on-going interventions to improve IC practices, diagnostics and AMS. This study looked into AMR patterns from clinical isolates, rates of hospital acquired infections (HAI) and clinical outcomes. Result(s): Over all, 98,915 samples were sent for culture from 158,191 admitted patients. Most commonly isolated organism was E. coli (n = 6951;30.1%) followed by Klebsiella pneumoniae (n = 5801;25.1%) and Pseudomonas aeroginosa (n = 3041;13.1%). VRE (Vancomycin resistant Enterococcus) rates fell down from 43.5% in Jan-June 2016 to 12.2% in July-Dec 2021, same was seen in CR (carbapenem resistant) Pseudomonas (23.0%-20.6%, CR Acinetobacter (66.6%-17.02%) and CR E. coli (21.6%-19.4%) over the same study period. Rate of isolation of Candida spp. from non-sterile sites also showed reduction (1.68 per 100 patients to 0.65 per 100 patients). Incidence of health care associated infections also fell from 2.3 to 1.19 per 1000 line days for CLABSI, 2.28 to 1.88 per 1000 catheter days for CAUTI. There was no change in overall mortality rates across the study period. Conclusion(s): This study emphasizes the point that improving compliance to standard IC recommendations and improving diagnostics can help in reducing the burden of antimicrobial resistance.Copyright © 2023 Indian Association of Medical Microbiologists
ABSTRACT
The debate on folic acid fortification of food to prevent neural tube defects in babies, for example, hasn't progressed in more than two decades (doi:10.1136/bmj.p1158).8 The worrying rise in perinatal suicides requires better funded services and support for women and young families to prevent deaths (doi:10.1136/bmj-2023-075414).9 And are the mandatory school inspections that harm the mental health of teaching staff even necessary (doi:10.1136/bmj.p1147)?10 The same applies to overzealous and discriminatory processes implemented by medical regulatory bodies such as the General Medical Council, despite claims of improvement by its chief executive (doi:10.1136/bmj.p1295 doi:10.1136/bmj.p1252).1112 The prevention principle would urge us to support a ban on vaping (doi:10.1136/bmj.p1266) and consider new options for reducing the number of days people experience migraines (doi:10.1136/bmj.p1249).1314 It would also induce bewilderment at the decision to wind down the UK's world leading covid surveillance network when covid-19 is still with us and future pandemics are inevitable (doi:10.1136/bmj.p1157).15 It would not, however, lend support to a non-evidence based screening programme for haemochromatosis (doi:10.1136/bmj.p1264).16 The first steps of an "avoid, reduce, reuse, recycle, research, rethink” framework (doi:10.1136/bmj-2021-069044) focus on better clinical practice that avoids low value care and inappropriate admissions and minimises blood tests and other interventions.17 This latest article in our series on achieving net zero and environmental sustainability in clinical practice examines critical care. The challenge isn't entirely a clinical one, because achieving net zero will depend on commitment across healthcare professions, engineering, waste management, hospital leadership, and beyond. A research paper assessing the value of routine monitoring of people being treated with methotrexate finds that frequency of monitoring should be adjusted according to risk, reducing the burden of work on clinical staff and making life more manageable for patients (doi:10.1136/bmj-2022-074678 doi:10.1136/bmj.p1120).1819 The difficulty here is one of getting research into practice, a timescale of 17 years by some estimates.
ABSTRACT
Introduction: Immune mediated necrotizing myopathy (IMNM) is a rare, but progressive disease that accounts for about 19% of all inflammatory myopathies. Dysphagia occurs in 20-30% of IMNM patients. It often follows proximal muscle weakness and ensues in the later stages of the disease. We report a rare case of IMNM, presenting with dysphagia as the initial symptom, followed by proximal muscle weakness. Case Description/Methods: A 74-year-old male with a past medical history of coronary artery disease, hypertension, and hyperlipidemia presented to the ED with 2-3 weeks of intractable nausea, vomiting, and dysphagia for solids and liquids. Vital signs were stable, and initial labs displayed an AST of 188 U/L and ALT of 64 U/L with a normal bilirubin. Computed tomogram of the chest, abdomen, and pelvis were negative. An esophagram showed moderate to severe tertiary contraction, no mass or stricture, and a 13 mm barium tablet passed without difficulty. Esophagogastroduodenoscopy exhibited a spastic lower esophageal sphincter. Botox injections provided no significant relief. He then developed symmetrical proximal motor weakness and repeat labs demonstrated an elevated creatine kinase (CK) level of 6,357 U/L and aldolase of 43.4 U/L. Serology revealed positive PL-7 autoxantibodies, but negative JO-1, PL-12, KU, MI-2, EJ, SRP, anti-smooth muscle, and anti-mitochondrial antibodies. Muscle biopsy did not unveil endomysial inflammation or MHC-1 sarcolemmal upregulation. The diagnosis of IMNM was suspected. A percutaneous endoscopic gastrostomy feeding tube was placed as a mean of an alternative route of nutrition. He was started on steroids and recommended to follow up with outpatient rheumatology. He expired a month later after complications from an unrelated COVID-19 infection. Discussion(s): The typical presentation of IMNM includes painful proximal muscle weakness, elevated CK, presence of myositis-associated autoantibodies, and necrotic muscle fibers without mononuclear cell infiltrates on histology. Dysphagia occurs due to immune-mediated inflammation occurring in the skeletal muscle of the esophagus, resulting in incoordination of swallowing. Immunotherapy and intravenous immunoglobulin are often the mainstay of treatment. Our patient was unique in presentation with dysphagia as an initial presenting symptom of IMNM, as well as elevated enzymes from muscle breakdown. It is critical as clinicians to have a high degree of suspicion for IMNM due to the aggressive nature of the disease and refractoriness to treatment.
ABSTRACT
Introduction: Lactulose is a non-absorbable disaccharide which acts in the large bowel, and is commonly used in the treatment of hepatic encephalopathy. We present an interesting case of altered mental status due to hepatic encephalopathy successfully managed with lactulose in a patient with history of total colectomy. Case Description/Methods: A 67-year-old male with non-alcoholic cirrhosis and inflammatory bowel disease (IBD) post total proctocolectomy with a continent ileostomy known as a Kock-pouch (K-pouch) presented to the hospital with flu like symptoms and altered mental status. He was subsequently found to be positive for COVID-19. At the time of initial evaluation, the patient was obtunded with an elevated ammonia level of 91 umol/L. Colorectal surgery was consulted as the patient was not able to empty his K-pouch. Recently, he complained of inability to catheterize and with bleeding from the stoma. Initial catheterization with a Water's tube yielded 400 cc of effluent. Nasogastric tube was placed through which he was receiving lactulose 30 mg q8 hours. The patient's mental status improved within 24 hours. The patient ultimately underwent flexible pouchoscopy with endoscopic dilation and placement of a 22 French mushroom catheter for decompression of the K-pouch. Discussion(s): Lactulose is a non-absorbable disaccharide composed of galactose and fructose. The small intestine does not have the enzymes required to breakdown lactulose so it reaches the large bowel in its original form. In the large bowel, it is metabolized by colonic bacteria into monosaccharides and then to volatile fatty acids, hydrogen and methane. Lactulose decreases both the production and absorption of ammonia mainly through the presence of gut bacteria. The question arises as to how lactulose decreased ammonia levels in this patient without a large bowel. One proposed mechanism is the translocation of bacteria normally found in the large bowel to the small intestine. Small Intestinal Bacterial Overgrowth (SIBO), is a condition causing an increased number of bacteria in the small intestine. Patients with IBD and structural abnormalities are at increased risk of developing SIBO. Lactulose is commonly used in the diagnosis through the administration of lactulose and subsequent measurements of hydrogen and methane gas in expired air. This condition, in our patient with history of ulcerative colitis and colectomy, is a proposed mechanism of the efficacy of lactulose in the treatment of hepatic encephalopathy.
ABSTRACT
Introduction: Enteral feeding is a physiologic process of providing adequate nutrition and has been shown to improve both mortality and quality of life in patients with inadequate oral intake. Improved critical care medicine and recent wave of Coronavirus Disease 2019 (COVID-19) has left us with a large proportion of patients needing alternative enteral nutrition. Although rare, intussusception is an important differential for patients presenting with acute abdominal pain post makeshift percutaneous endoscopic gastrostomy (PEG) tube placement. Case Description/Methods: A 58-year-old male was admitted to the hospital for coffee ground emesis over three days accompanied with epigastric pain. He had right sided hemiparesis secondary to cerebrovascular accident with PEG tube for enteral nutrition. Examination was significant for epigastric tenderness with normal bowel sounds. PEG tube aspiration revealed bile-tinged fluid. Significant labs included white blood cell count of 11,600 /mm3, hemoglobin 10.2 g/dL, and lactic acid of 2.3 mmol/L. A computerized tomography of the abdomen with IV contrast showed a small segment duodeno-duodenal intussusception at the horizontal segment around the distal end of the tube was noted (Figure A). An urgent esophagogastroduodenoscopy (EGD) revealed a Foley catheter acting as a makeshift PEG tube extending across the pylorus into the duodenum. The distal tip of the Foley catheter was visualized with an inflated balloon seen in the third portion of the duodenum (Figure B) The inflated catheter balloon acted as a lead point causing intussusception in a ball-valve effect. The balloon was deflated, and the catheter was replaced (Figure C) with a 20 Fr PEG tube. Discussion(s): Gastric outlet obstruction is an uncommon complication reported in few cases caused by migration of the gastrostomy tube. Rarely this migrating gastrostomy tube can invaginate the duodenum or the jejunum causing intussusception. Only handful of cases have been reported in the literature. Patients usually present with epigastric pain, vomiting or rarely hematemesis. CT scan of the abdomen is the investigation of choice. Amidst the pandemic and supply shortage, Foley catheters have been deemed as a viable alternative to gastrostomy tubes and are being used more often. It is important to recognize this rare complication and use of balloon catheter should raise further suspicion. Timely endoscopic intervention can help avoid bowel necrosis and surgical intervention.
ABSTRACT
Introduction: Patients with COVID pneumonia who require intubation and prolonged mechanical ventilation are at risk for complications such as recurrent infection, tracheomalacia, tracheal stenosis, and the development of tracheoesophageal fistula (TEF). TEF is a devastating complication where the trachea and esophagus develop an abnormal connection in the lower airway that dramatically increases the mortality of critically ill patients by recurrent aspiration and pneumonias. Though commonly associated with neoplasms another risk is pressure induced ischemia of the common wall between the trachea and esophagus. This can occur due to overinflation of the endotracheal (ET) cuff, especially with concomitant use of a nasogastric tube (NGT). Definitive management requires surgical repair. Case Description/Methods: A 69-year-old male patient presented with acute hypoxemic respiratory failure secondary to COVID pneumonia requiring intubation and insertion of an NGT. On day 29 the patient underwent percutaneous enterogastrostomy (PEG) placement and tracheostomy;it was noted intraoperatively that the tracheal mucosa was inflamed and friable. On day 36 bronchoscopy was performed through the tracheostomy tube due to concerns for mucus plugging. Friable mucosa with granulation tissue was seen at the distal end of the tube, so an extra-long tracheostomy tube was exchanged to bypass the granulation tissue. Later that night the ventilator measured a 50% discrepancy between the delivered and exhaled tidal volumes, triggering an alarm. Exam noted distension of the PEG-bag with a fluid meniscus in the tubing moving in sync with each respiration. TEF was considered and bronchoscopic evaluation confirmed a 1-centimeter TEF. The patient underwent successful TEF repair and is slowly recovering (Figure). Discussion(s): Critically ill patients who require prolonged support are at high risk of complications and device related injury. With each device-day there is an increased risk of complications, such as infection, dislodgement, and pressure-related injuries. This case highlights the importance of serial physical examinations as well as understanding possible device related complications. An unexpected finding, such as a persistent air leak, air in a PEG bag, or a fluctuating meniscus should raise suspicion for the development of a serious complication and would warrant prompt confirmatory testing. Our literature review revealed no reports of a PEG tube abnormalities as a presenting finding for TEF.
ABSTRACT
Introduction: The mortality rate of patients hospitalized with a lower gastrointestinal bleed has been reported at 1.1% in the United States from 2005 to 2014. Pseudoaneurysms, typically associated with pancreatitis, have been described in case reports as a rare condition with a small subset presenting as gastrointestinal bleeding. Our study describes a rare case of recurrent lower gastrointestinal bleeding diagnosed as a pseudoaneurysm by endoscopy and angiography. Case Description/Methods: A 38-year-old male presented to our facility from a long-term care facility with hematochezia and blood clots per gastrostomy-jejunostomy. He had recently been hospitalized for severe coronavirus disease 2019 with a complicated hospital course in the intensive care unit including necrotizing pancreatitis with an abdominal drain, multiple secondary infections, tracheostomy, and percutaneous endoscopic gastrostomy-jejunostomy. On previous hospitalization, he was found to have a small pseudoaneurysm of the gastroduodenal artery and received embolization of the gastroduodenal and gastroepiploic arteries at that time. During transport to our hospital, he was noted to have tachycardia, hypotension requiring norepinephrine, and was transfused one unit of red blood cells. Hemoglobin at this time was 7.5 g/dl after transfusion. Esophagogastroduodenoscopy was completed and showed a gastrojejunostomy tube in the expected location but was noted to be tight to the mucosa, which was pale in appearance. Flexible sigmoidoscopy revealed localized areas of edematous and erythematous mucosa with some associated oozing throughout the sigmoid colon. Repeat evaluation was completed one week later due to recurrent hematochezia. Colonoscopy was performed with identification of an apparent fistulous tract in the sigmoid colon located at 35 cm. Computed tomography angiography localized a pseudoaneurysm arising from the marginal artery of Drummond just proximal to its anastomosis with the ascending branch of the left colic artery and was successfully embolized. Discussion(s): Pseudoaneurysms, such as the one described in this case, have been shown to be associated with pancreatitis and can result if a pseudocyst involves adjacent vasculature. Gastrointestinal bleeding is a rare presentation of this condition. However, this case highlights the importance of repeat colonoscopy and angiography in the setting of a lower gastrointestinal bleed of unknown etiology.

ABSTRACT
Introduction: Orogastric tube insertion is a routine procedure in medical care. However, misplacement of the tube can cause a variety of complications, which can be life threatening in some instances. Case Description/Methods: 71-year-old male presented with dyspnea, fever, chills, cough, and myalgia for 2 weeks. He had tachycardia, tachypnea, and was hypoxic to 66% in room air. He was found to have acute hypoxic respiratory failure secondary to COVID-19 Pneumonia and was admitted to ICU. But, he continued to be hypoxic and was started on BiPAP. He eventually became altered, and was intubated. Post intubation orogastric tube (OGT) placement was unsuccessful on the first attempt due to resistance. On the second attempt, the nurse was able to advance partially (Figure). But, a chest XR showed OGT in the mediastinum, and OGT was removed. CT of neck and chest revealed pneumomediastinum with possible mid-thoracic esophageal perforation. The patient was started on broad-spectrum antibiotics and thoracic surgery was consulted. Given his mechanical ventilation requirement, surgery deemed him unfit to tolerate thoracotomy and the endoscopic procedure was not available in the hospital. So, recommendation was to manage conservatively. His hospital course was complicated by hypotension requiring vasopressors and metabolic acidosis in setting of acute renal failure requiring CRRT. Code status was changed by the family to Do Not Resuscitate due to his deteriorating condition. Eventually, he had a PEA arrest and was expired. Discussion(s): OGT intubation is performed at hospitals for feeding, medication administration or gastric decompression. Although it is considered a safe procedure, complications can arise due to OGT misplacement or trauma caused by the OGT itself or the intubation process. OGT misplacement is typically endotracheal or intracranial. Misplacement within the upper GI lumen is usually detected by a kink in the oropharynx or esophagus. The subsequent complications are identified by the structure that is perforated (e.g., mediastinitis or pneumothorax). Regardless of whether counteraction is perceived, the physician must be careful not to apply excessive force. The location of the OGT tip should be determined by a chest radiograph;visualization of the tip below the diaphragm verifies appropriate placement. Complications of OGT insertion are uncommon;however, the consequences are potentially serious, and the anatomy of the upper GI tract should be understood by all who are involved in the care.
ABSTRACT
Introduction: Biliary fistulas are a rare complication of gallstones. Fistula formation can occur in a number of adjacent sites;even more rare complication is the formation of a cholecystocolonic fistula. Case Description/Methods: A 74-year-old man who had recently undergone an extensive hospitalization secondary to inflammatory demyelinating polyneuropathy (IDP) and COVID-19 infection. During his hospitalization, he required ICU admission and mechanical ventilation with subsequent PEG tube placement. He was discharged to an inpatient rehabilitation facility when he developed worsening respiratory distress. Laboratory examinations were pertinent for ALT of 252, AST of 140 and ALP of 401 without hyperbilirubinemia. Blood cultures revealed Escherichia coli bacteremia. Given transaminitis and bacteremia, an MRCP was performed which demonstrated evidence absent space between gallbladder and hepatic flexure of the colon suggesting a CCF (Figure A). An ERCP with sphincterotomy was performed which showed extravasation of contrast from the gallbladder into the colon at the hepatic flexure (Figure B). He underwent cholecystectomy and fistula repair without any complications and gradual improvement in liver function test. He was discharged to a rehabilitation facility. Discussion(s): Complications of gallstones are well established, which include the common bile duct obstruction, but also include the rare occurrences of acute cholangitis, malignancy, and fistula formation. CCF is a rare complication of gallstones which can occur in the stomach, duodenum, or colon with a variable clinical presentation. Complications from an undiagnosed fistula can be life threatening including colon perforation and fecal peritonitis. This case highlights the diagnostic challenge and the high degree of clinical suspicion involved in establishing the diagnosis of CCF in patient without abdominal symptoms suggestive of gallbladder disease. We hypothesize that stone formation resulting in the development of the fistula may be secondary to the underlying history of IDP and subsequent immobility. Although rare, CCF should be considered in patients presenting with unexplained pneumobilia and bacteremia. A timely diagnosis should be made to proceed with immediate treatment including cholecystectomy and fistula closure to prevent fatal complications.
