Gastric outlet obstruction caused by heterotopic pancreas in a patient with alcohol use disorder.

INTRODUCTION AND IMPORTANCE: Heterotopic Pancreas (HP) is defined by the presence of pancreatic tissue in an anatomically distinct location from the main pancreas. While often clinically silent, it may present symptomatically. If located in the gastric antrum, HP may cause gastric outlet obstruction (GOO). The objective of this paper is to present a rare case of HP in the gastric antrum causing GOO. CASE PRESENTATION: Herein, we report a 43-year-old man who presented with abdominal pain and non-bilious emesis in the setting of COVID-19 infection and alcohol consumption. During the initial workup, computed-tomography (CT) was non-specific but demonstrated GOO, concerning for cancer. Cold forceps biopsies taken during esophagogastroduodenoscopy (EGD) confirmed benign HP. Since the patient was symptomatic from gastric outlet compression, he underwent resection via laparoscopic distal gastrectomy and Billroth II gastrojejunostomy. At 1-month postoperative follow-up, the patient recovered uneventfully. We hypothesized that GOO by HP in this case may have been associated with cumulative effects of alcohol consumption and COVID-19 infection on the ectopic tissue. CLINICAL DISCUSSION: HP is rare and difficult to diagnose preoperatively. When located in gastric antrum, HP can cause GOO, mimicking gastric malignancy. Combination of EGD/EUS, biopsy/FNA, and surgical resection are necessary to definitively make the diagnosis. Finally, it is important to consider that heterotopic pancreatitis or structural changes in HP may occur due to classic pancreatic stressors like alcohol and viral infections. CONCLUSION: HP may cause GOO presenting with non-bilious emesis and abdominal pain, mistaken for malignancy on CT imaging.

Bronchoscopy-guided removal of intrabronchial coil migration after coil embolization of pulmonary arteriovenous malformation.

Pulmonary arteriovenous malformations develop in approximately 50% of hereditary hemorrhagic telangiectasia patients. Pulmonary arteriovenous malformations are often treated with coil embolization therapy. We report a case of a 45-year-old female with multiple pulmonary arteriovenous malformations due to underlying hereditary hemorrhagic telangiectasia who had undergone 14 coil embolization procedures over 16 years. She presented with sudden onset severe, unremitting, nonproductive cough from a foreign body sensation in the airway. Computed tomography of the chest demonstrated a metallic foreign body extending from the left lower lobe of the lung into the left mainstem bronchus and trachea. Bronchoscopy-guided removal of the foreign body revealed an intact embolization coil placed 8 years prior to presentation had partially migrated through the vessel and airway walls into the airway lumen, extending from the left lower lobe bronchus to the left mainstem bronchus. Coil migration is a rare, but potentially dangerous, complication of coil embolization therapy.

The Effect Modification of Ultrasound Risk Classification on Molecular Testing in Predicting the Risk of Malignancy in Cytologically Indeterminate Thyroid Nodules.

Background: Thyroid nodules with indeterminate cytology are increasingly subjected to molecular testing. We evaluated the diagnostic performances of Afirma Genomic Sequencing Classifier (GSC) and ThyroSeq v3 in thyroid nodules with high versus low/intermediate suspicion ultrasound classification. Methods: In this prospective cohort study, we analyzed all Bethesda III and IV thyroid nodules that underwent fine-needle aspiration biopsies in the University of California Los Angeles Health System from July 2017 to April 2020. All patients underwent molecular testing with Afirma GSC or ThyroSeq v3 as part of an institutional randomized trial (NCT02681328). Nodules were categorized according to the American Thyroid Association (ATA) ultrasound risk classification. The benign call rate and the positive predictive value of molecular testing were compared between ATA high suspicion versus all other categories. Results: A total of 343 patients with 375 indeterminate thyroid nodules were included. The malignancy rate in ATA high suspicion nodules was not significantly increased by a suspicious Afirma GSC result (77.8% for all ATA high suspicion nodules vs. 87.5% for nodules with ATA high suspicion and suspicious Afirma GSC results, positive likelihood ratio [LR] = 2.0, 95% confidence interval [CI 0.5-8.0], p = 1.0) or by a positive ThyroSeq v3 result (80.0% vs. 80.0%, positive LR = 1.0 [CI 1.0-1.0], p = 1.0). The rate of malignancy in ATA low/intermediate suspicion nodules increased from 21.0% to 56.3% with a suspicious Afirma GSC result (positive LR = 4.8 [CI 3.4-6.9], p < 0.0001) and decreased to 3.8% with a benign Afirma GSC result (negative LR = 0.1 [CI 0.07-0.3], p < 0.0001). Similarly, the rate of malignancy in ATA low/intermediate suspicion nodules increased from 24.3% to 66.7% with a positive ThyroSeq v3 result (positive LR = 6.2 [CI 4.0-9.7], p < 0.0001) and decreased to 2.1% with a negative ThyroSeq v3 result (negative LR = 0.07 [CI 0.02-0.3], p < 0.0001). Conclusions: Afirma GSC and ThyroSeq v3 performed well in ruling out malignancy in sonographically low/intermediate suspicion thyroid nodules but has limited diagnostic value in sonographically high suspicion nodules. Molecular testing can prognosticate more aggressive thyroid cancers, which can inform treatment decisions.

Patient-Centered Decision-making for Postoperative Narcotic-Free Endocrine Surgery: A Randomized Clinical Trial.

Importance: Historically, opioid pain medications have been overprescribed following thyroid and parathyroid surgery. Many narcotic prescriptions are incompletely consumed, creating waste and opportunities for abuse. Objective: To determine whether limiting opioid prescriptions after outpatient thyroid and parathyroid surgery to patients who opt in to narcotic treatment reduces opioid consumption without increasing postoperative pain compared with usual care (routine narcotic prescriptions). Design, Setting, and Participants: A randomized clinical trial of Postoperative Opt-In Narcotic Treatment (POINT) or routine narcotic prescription (control) was conducted at a single tertiary referral center from June 1 to December 30, 2020. A total of 180 adults undergoing ambulatory cervical endocrine surgery, excluding patients currently receiving opioids, were assessed for eligibility. POINT patients received perioperative pain management counseling and were prescribed opioids only on patient request. Patients reported pain scores (0-10) and medication use through 7 daily postoperative surveys. Logistic regression was used to determine factors associated with opioid consumption. Interventions: Patients in the POINT group were able to opt in or out of receiving prescriptions for opioid pain medication on discharge. Control patients received routine opioid prescriptions on discharge. Main Outcomes and Measures: Daily peak pain score through postoperative day 7 was the primary outcome. Noninferiority was defined as a difference less than 2 on an 11-point numeric rating scale from 0 to 10. Analysis was conducted on the evaluable population. Results: Of the 180 patients assessed for eligibility, the final study cohort comprised 102 patients: 48 randomized to POINT and 54 to control. Of these, 79 patients (77.5%) were women and median age was 52 (interquartile range, 43-62) years. A total of 550 opioid tablets were prescribed to the control group, and 230 tablets were prescribed to the POINT group, in which 23 patients (47.9%) opted in for an opioid prescription. None who opted out subsequently required rescue opioids. In the first postoperative week, 17 POINT patients (35.4% of survey responders in the POINT group) reported consuming opioids compared with 27 (50.0%) control patients (P = .16). Median peak outpatient pain scores were 6 (interquartile range, 4-8) in the control group vs 6 (interquartile range, 5-7) in the POINT group (P = .71). In multivariate analysis, patients with a history of narcotic use were 7.5 times more likely to opt in (95% CI, 1.61-50.11; P = .02) and 4.8 times more likely to consume opioids (95% CI, 1.04-1.52; P = .01). Higher body mass index (odds ratio, 1.11; 95% CI, 1.01-1.23; P = .03) and highest inpatient postoperative pain score (odds ratio, 1.24; 95% CI, 1.04-1.52; P = .02) were also associated with opioid consumption. Conclusions and Relevance: In this trial, an opt-in strategy for postoperative narcotics reduced opioid prescription without increasing pain after cervical endocrine surgery.
