Endoscopic vacuum therapy for treatment of spontaneous and iatrogenic upper gastrointestinal defects.

BACKGROUND/AIMS: Endoscopic vacuum therapy (EVT) can heal a variety of defects within the gastrointestinal (GI) tract via applying negative pressure, which reduces the defect size, aspirates the infected fluid, and promotes granulation tissue. Here we present our experience with EVT as it relates to both spontaneous and iatrogenic upper GI tract perforations, leaks, and fistulas. METHODS: This retrospective study was conducted at four large hospital centers. All patients who underwent EVT between June 2018 and March 2021 were included. Data on multiple variables were collected, including demographics, defect size and location, number and intervals of EVT exchanges, technical success, and hospital length of stay. Student t-test and the chi-squared test were used to analyze the data. RESULTS: Twenty patients underwent EVT. The most common defect cause was spontaneous esophageal perforation (50%). The most common defect location was the distal esophagus (55%). The success rate was 80%. Seven patients were treated with EVT as the primary closure method. The mean number of exchanges was five with a mean interval of 4.3 days between exchanges. The mean length of hospital stay was 55.8 days. CONCLUSION: EVT is a safe and effective initial management option for esophageal leaks and perforations.

Esophageal Perforation Successfully Treated With EVT.

Esophageal perforation is rare and carries high morbidity and mortality. A high degree of suspicion is needed for timely diagnosis and treatment. A 54-year-old man presented with fever and confusion. Imaging revealed air in the hepatic inferior vena cava and concern for a fistula between the distal esophagus and the inferior vena cava. An upper endoscopic evaluation revealed a dental floss pick penetrating the distal esophagus. The foreign body was removed, and endoluminal vacuum therapy was used to close the perforation. Endoluminal vacuum therapy is an emerging therapy to treat full-thickness gastrointestinal injuries.

Nonvariceal upper GI hemorrhage after percutaneous coronary intervention for acute myocardial infarction: a national analysis over 11 months.

BACKGROUND AND AIMS: Nonvariceal upper GI hemorrhage (NVUGIH) is a feared adverse event after percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). We aimed to determine the incidence of NVUGIH after PCI for AMI and its impact on mortality, morbidity, and health care resource utilization over 11 months. METHODS: We used the Nationwide Readmission Database 2014. Inclusion criteria were (1) a principal diagnosis of ST or non-ST-elevation myocardial infarction, (2) in-hospital PCI, and (3) admission in January. Exclusion criteria were age less than 18 years and elective admission. The primary outcome was the 11-month incidence of NVUGIH. Secondary outcomes were 11-month mortality rate, prolonged mechanical ventilation, shock, upper endoscopy, length of stay, and total hospitalization costs and charges. Independent risk factors for NVUGIH were identified using multivariate logistic regression analysis. RESULTS: A total of 22,669 patients were included in the study. The mean age was 63.8 years (range, 63.4-64.1 years), and 31.7% of patients were female. The 11-month incidence of NVUGIH was 1.6%. The onset of NVUGIH was associated with an increase in the 11-month mortality rate (adjusted odds ratio, 1.94; 95% confidence interval, 1.01-3.72; P =.04). The upper endoscopy, shock, and prolonged mechanical ventilation rates were 72%, 6.2%, and 1.9%, respectively. In total, 26,532 days were associated with NVUGIH, with a total health care in-hospital economic burden of U.S.$17.6 million. Independent predictors of NVUGIH were female gender, Charlson comorbidity score, and length of stay. CONCLUSIONS: The 11-month incidence of NVUGIH among patients who undergo PCI for AMI is 1.6%. NVUGIH has a substantial impact on mortality, morbidity, and in-hospital health care resource utilization.

Serrated polyp detection rate and advanced adenoma detection rate from a US multicenter cohort.

BACKGROUND: Interval colorectal cancers may be associated with a low serrated polyp detection rate (SDR) and advanced adenoma detection rate (AADR). We aimed to determine the SDR and AADR for endoscopists in a United States multicenter cohort. METHODS: We included average-risk screening colonoscopies from five medical centers in the United States. Endoscopists with data on at least 100 average-risk screening colonoscopies were included. We calculated median SDR and AADR for endoscopists with adequate adenoma detection rates (ADRs) > 25 %. We analyzed the relationship between ADR and SDR, and between ADR and AADR using nonparametric Spearman correlation coefficients, scatter plots, and linear regression. RESULTS: We included 3513 screening colonoscopies performed by 26 gastroenterologists. The mean age of patients was 56.8 years (SD 7.4) and 1585 (45 %) were male. All but one endoscopist had an ADR above 25 %. There was a significant positive but modest correlation between ADR and SDR (rho = 0.67, P < 0.01), and between ADR and AADR (rho = 0.56, P < 0.01). For endoscopists with an adequate ADR, median (interquartile range) ADR was 43 % (32.0 % - 48.6 %), median SDR was 8.4 % (7.3 % - 11.4 %), and median AADR was 9.3 % (6.4 % - 12.6 %). CONCLUSION: A significant percentage of endoscopists have either a low SDR or low AADR despite an adequate ADR, justifying the need for separate SDR and AADR benchmarks. Based on our multicenter cohort, endoscopists with adequate ADRs had a median SDR and median AADR of about 8 % and 9 %, respectively.

Outcomes of delayed endoscopic management for esophageal soft food impactions.

BACKGROUND AND AIMS: Food impactions are a common reason for emergent upper endoscopy. Current guidelines call for urgent upper endoscopy (within 24 hours) for food impactions without complete esophageal obstruction and emergent endoscopy (within 6 hours) for those with complete esophageal obstruction. Multiple adverse events can arise from esophageal foreign bodies. Cases with longer delays from symptom onset to presentation have been associated with higher rates of surgical intervention. However, data on esophageal soft food impactions are scant. We set out to determine differences in outcomes for food impactions undergoing intervention within 12 hours versus over 12 hours of symptom onset. METHODS: A retrospective review of medical records was conducted to identify patients who presented to our hospital with an esophageal soft food impaction and underwent an EGD between January 2010 and January 2018. Patients were divided into 2 groups based on the timing from symptom onset to EGD. An EGD within 12 hours was considered an early intervention and over 12 hours was considered a delayed intervention. Patients who had ingested bones or hard objects were not included. Primary outcomes studied were rates of aspiration, admission, local esophageal adverse events, and 30-day all-cause mortality. RESULTS: We identified 110 patients with a soft food impaction who underwent an EGD. Forty- two patients had an early intervention and 68 a delayed intervention. There were no differences in basic demographics and comorbidities. Additionally, there were no differences in rates of local esophageal adverse events, aspiration, admission, or 30-day mortality. Multivariate analysis revealed endoscopic accessory use was associated with increased odds of local esophageal adverse events (odds ratio, 6.37; P = .01). CONCLUSIONS: The overall rates of serious adverse events in esophageal soft food impactions are low. Delayed intervention is not associated with increased adverse events or 30-day mortality compared with early intervention. However, accessory use is associated with higher adverse event rates.

Accuracy of endoscopic ultrasound in esophageal cancer staging.

Since its advent in the 1980s endoscopic ultrasound (EUS) has played an important role in the diagnosis, staging, and therapeutic management of various gastrointestinal malignancies. EUS has emerged as a vital tool in the evaluation of esophageal cancer as it provides a detailed view of the layers of the esophageal wall and surrounding tissues. This permits determination of tumor invasion depth and local lymph node metastases. It is the most sensitive and specific method available for locoregional staging of esophageal cancer. The information obtained via EUS is vital in determining the appropriate diagnosis, prognosis, and treatment options. Thus, this article aims to present a review of the accuracy and utilization of EUS in the staging of esophageal cancer.

Recurrence of hepatocellular carcinoma at the porta-hepatis following liver transplantation diagnosed on EUS-FNA.

Hepatocellular carcinoma (HCC) is a potentially fatal complication of chronic liver disease. Liver transplantation is now the preferred treatment due to good outcomes. We present a unique case of recurrence of HCC at the porta hepatis four years after orthotopic liver transplantation diagnosed via endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). Our report also highlights that intrahepatic recurrence of HCC can be surgically treated. However, further studies are needed to develop treatment algorithms for intra-hepatic recurrence of HCC post liver transplantation.

Evaluation and management of Non-variceal upper gastrointestinal bleeding.

Non-variceal upper gastrointestinal bleeding continues to be an important cause of morbidity and mortality. The most common causes include peptic ulcer disease, Mallory-Weiss syndrome, erosive gastritis, duodenitis, esophagitis, malignancy, angiodysplasias and Dieulafoy's lesion. Initial assessment and early aggressive resuscitation significantly improves outcomes. Upper gastrointestinal endoscopy continues to be the gold standard for diagnosis and treatment. We present a comprehensive review of literature for the evaluation and management of non-variceal upper gastrointestinal bleeding.

Evaluation and management of variceal bleeding.

Acute variceal bleeding is one of the most fatal complications of cirrhosis and is responsible for about one-third of cirrhosis-related deaths. Therefore, every effort should be made to emergently resuscitate the patients, start pharmacotherapy as soon as possible and do endoscopic therapy in a timely manner. Despite the recent advances in treatment, mortality rate is still high. We provide a comprehensive review of evaluation and management of variceal bleeding.
