ABSTRACT

BACKGROUND: Peroral endoscopic myotomy (POEM) is increasingly used to treat esophageal achalasia, but is associated with a high rate of gastroesophageal reflux disease (GERD). The aim of our meta-analysis was to compare short and standard POEM in terms of clinical success and postoperative GERD. METHODS: We conducted a systematic review and meta-analysis of studies that compared POEM using short myotomy with standard myotomy. The primary outcome was clinical success. Secondary outcomes were postoperative GERD, perioperative complications, operation time, and length of hospital stay. A random-effects model was used to calculate the risk ratios (RR), mean differences (MD), and confidence intervals (CI). A P-value <0.05 was considered statistically significant. RESULTS: We included 5 studies involving 474 esophageal achalasia patients. Short and standard myotomies were similar in terms of clinical success (RR 1.02, 95%CI 0.97-1.09), perioperative complications (RR 0.68, 95%CI 0.26-1.75), and length of hospital stay (MD 0.25 days, 95%CI -0.14-0.63). Operation time was shorter for short myotomy (MD -15.01 mins, 95%CI -20.34 - -9.67). Although reflux symptoms were similar (RR 0.94, 95%CI 0.51-1.74), short myotomy had a lower risk of reflux esophagitis on endoscopy (RR 0.61, 95%CI 0.39-0.98), and pathologic acid exposure on pH monitoring (RR 0.58, 95%CI 0.36-0.94). CONCLUSIONS: POEM using a shorter myotomy is comparable with standard myotomy in terms of efficacy and safety in the short-term setting. A short myotomy requires a shorter operation time and might reduce the occurrence of postoperative GERD.

ABSTRACT

Dysphagia is a symptom with a broad differential diagnosis. Usually, the etiology of dysphagia is benign, but it is essential to rule out serious causes. It is also critical to think outside the box when the etiology is not obvious. Herein, we describe a case of multiple myeloma that initially presented with dysphagia. An 81-year-old male patient presented with dysphagia to solid food associated with anorexia and weight loss of 22 kg over the last 6 months. The patient looked chronically ill and cachectic. Upper endoscopy showed patchy erythema in the gastric antrum. Gastric biopsy was consistent with gastric amyloidosis. Although serum and urine protein electrophoresis did not show a monoclonal (M) band, immunofixation did show elevated free kappa light chains and elevated free Kappa/Lambda ratio. Bone marrow biopsy was consistent with multiple myeloma. Although gastrointestinal involvement is common in amyloidosis, it is unusual for amyloidosis to initially present in the gastrointestinal tract. Identification and treatment of the underlying condition, e.g., multiple myeloma, can lead to regression of gastrointestinal amyloidosis.

ABSTRACT

Esophagectomy is the mainstay surgical treatment for esophageal carcinoma. The operation can be complicated by an anastomotic stricture, anastomotic leak, recurrent laryngeal nerve injury, conduit ischemia, and chylothorax. Rarely, esophagectomy can be complicated by fistula formation between the gastrointestinal tract and the nearby structures. We describe a case of esophagopericardial fistula after esophagectomy. A 50-year-old man presented to the emergency room with a chest pain of two-week duration associated with sweating, chills, and poor appetite. He was diagnosed with stage III esophageal adenocarcinoma four months ago. He had received neoadjuvant chemotherapy followed by distal esophagectomy, partial gastrectomy, and placement of a jejunostomy tube one month before presentation. Cardiovascular examination was significant for jugular venous distention and distant heart sounds. Chest CT angiography showed pneumomediastinum concerning for anastomotic leak. Esophagram finally confirmed an esophagopericardial fistula. A drain was placed into the pericardial space followed by emergent esophageal stent placement. Eventually, he underwent a cervical esophagostomy and placement of a jejunostomy tube. The patient was later discharged home in a stable condition. In conclusion, esophagopericardial fistula is a rare adverse event of esophagectomy. Esophageal stenting could be useful as a temporary or definite treatment.

ABSTRACT

BACKGROUND: The differences in outcomes between acute biliary pancreatitis (ABP) and acute alcohol-induced pancreatitis (AAP) have not been well studied. We sought to examine the differences between ABP and AAP as regards to in-hospital outcomes and resource utilization, using a large nationwide database. METHODS: We queried the National Inpatient Sample databases 2016 and 2017 using the International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) coding system to identify the patients with a primary diagnosis of AAP and ABP. The primary outcome was all-cause in-hospital mortality. Secondary outcomes were hospital length of stay (LOS), hospitalization charge/cost, shock, acute kidney injury (AKI), intensive care unit (ICU) admission, and home discharge. Analysis was performed with STATA software. RESULTS: There was no significant difference in mortality between patients with AAP and ABP (0.42% vs. 0.82%, adjusted odds ratio [aOR] 0.95, 95% confidence interval [CI] 0.69-1.31; P=0.79). Patients with ABP had a significantly longer LOS (+0.48 days, P<0.001). Patients with ABP had significantly higher adjusted mean hospitalization charges ($+19,958, P<0.001) and costs ($+4,848, P<0.001). Patients with ABP had a significantly lower likelihood of shock (aOR 0.75, 95%CI 0.59-0.95; P=0.02), AKI (aOR 0.76, 95%CI 0.71-0.82; P<0.001) or ICU admission (aOR 0.74, 95%CI 0.62-0.88; P=0.001). They were more likely to be discharged home (aOR 1.26, 95%CI 1.18-1.34; P<0.001). CONCLUSION: Although there was no difference in all-cause mortality, patients with ABP had better hospitalization outcomes but greater resource utilization.

ABSTRACT

BACKGROUND: The role of anticoagulation in treating non-malignant portal vein (PV) thrombosis (PVT) in patients with liver cirrhosis remains unclear. In our meta-analysis, we aimed to evaluate the efficacy and safety of anticoagulation for the treatment of non-malignant PVT in these patients. METHODS: We conducted a meta-analysis to estimate the effects of anticoagulation on non-malignant PVT in patients with liver cirrhosis. We assessed the rates of PV recanalization, variceal bleeding, and any bleeding. RESULTS: We included 9 observational studies which involved 474 patients. The rate of PV recanalization was significantly higher in patients who received anticoagulation compared to those who did not: 65.2% vs. 25.2%; relative risk (RR) 2.31, 95% confidence interval (CI) 1.80-2.96; P<0.00001. Variceal bleeding was significantly lower in patients who received anticoagulation: 0.1% vs. 18.5%; RR 0.15, 95%CI 0.04-0.55; P=0.004. Any bleeding was similar between patients who received anticoagulation and those who did not: 10.3% vs. 22.7%; RR 0.43, 95%CI 0.09-1.99; P=0.28. CONCLUSIONS: Anticoagulation use increased the rate of PV recanalization in cirrhotic patients with non-malignant PVT. Anticoagulation decreased the rate of variceal bleeding and did not increase the rate of any bleeding.

ABSTRACT

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder that affects multiple systems throughout the body. Although there are multiple documented vasculopathies that can be seen in NF1, there are very few documented cases of coronary artery aneurysms with complete thrombosis of the ectatic vessel resulting in myocardial infarction. This case report describes a 28-year-old male with a past medical history of NF1 who presented with an anterolateral ST-segment elevation myocardial infarction. He underwent urgent cardiac catheterization, which was significant for severe thrombotic occlusion of the mid-left anterior descending artery (LAD) with thrombolysis in myocardial infarction (TIMI) flow 0. The LAD was noted to be severely ectatic. Percutaneous coronary intervention (PCI) with thrombectomy was attempted and was unsuccessful, with TIMI flow 0 after the intervention attempt. An echocardiogram was performed, which showed left ventricular ejection fraction (LVEF) of 30%-35%. This case report is presented to familiarize physicians with the rare vasculopathies that can occur in patients with NF1. Occlusive or aneurysmal disease can occur almost anywhere in the body in patients with NF1 due to the proliferation of fusiform endothelial cells in the blood vessels.

ABSTRACT

Ganglioneuromas are slow-growing hamartomatous tumors that are rarely found in the colon. There are three subtypes of ganglioneuromas: polypoid ganglioneuroma, ganglioneuromatous polyposis, and diffuse ganglioneuromatosis. They are differentiated depending on their endoscopic and histological characteristics. Patients with colonic ganglioneuroma may present with nonspecific symptoms; however, they are usually asymptomatic. We present a case of hematochezia, where an ascending colon ganglioneuroma was found incidentally on diagnostic colonoscopy. We will explain how to distinguish the three subtypes of ganglioneuroma on colonoscopy and will mention the genetic disorders associated with them. We will also discuss the treatment of ganglioneuromas.

ABSTRACT

Type 1 myotonic dystrophy (MD) is a rare inherited disease which presents with skeletal muscle weakness and myotonia. Involvement of smooth muscles is also common and mainly manifests in the gastrointestinal tract. We report a case of type 1 MD who presented with dysphagia and was found to have unique esophageal manometry findings. A 57-year-old male patient presented with dysphagia for the last few months. Past medical history was significant for type 1 myotonic muscular dystrophy, gastroesophageal reflux disease, diaphragmatic paralysis, and obstructive sleep apnea. Both his father and brother died in their 50s because of unclear respiratory problems. He was a former smoker and did not drink alcohol. Review of systems was unremarkable. His neurological examination was significant for bilateral facial muscle weakness and mild ptosis. He had atrophy and weakness of the distal upper and lower extremities. Deep tendon reflexes were absent. Upper endoscopy and 24-hour esophageal pH testing were non-diagnostic. Finally, esophageal manometry revealed elevated lower esophageal sphincter (LES) pressure, elevated upper esophageal sphincter (UES) pressure, and very week peristalsis of the esophageal body. Esophageal involvement is common in type 1 MD manifesting with dysfunction of UES, esophageal body, and LES. Manometry usually describes a reduced resting tone of the UES and LES. The patient had elevated LES pressure and week peristalsis of the esophageal body consistent with achalasia. He also had an elevated UES pressure consistent with cricopharyngeal achalasia. This is the opposite of what is expected in type 1 MD.

ABSTRACT

Acute pancreatitis is a sudden inflammatory condition of the pancreas, caused mainly by gallstones and alcohol abuse. A significant proportion of acute pancreatitis cases remain idiopathic. Recent reports have highlighted cannabis use as an etiology of acute pancreatitis. A few case reports are available that report the association of cannabis with acute pancreatitis. Considering the global use of cannabis medically and illicitly, it becomes imperative to explore this adverse effect of cannabis use especially in idiopathic cases of acute pancreatitis. Here, in this report, we present a case of acute pancreatitis with no obvious cause. The patient was a 48-year-old female with no history of alcohol use. She had a history of cholecystectomy with normal serum triglycerides and calcium levels. The patient was consuming marijuana (cannabis) daily for the last three years. The diagnosis of cannabis-induced acute pancreatitis was made in the patient after other causes were excluded. It is difficult to distinguish cannabis-induced pancreatitis as there are no clear and specific associated clinical features. The diagnosis of cannabis-induced pancreatitis becomes even more challenging due to the use of multiple drugs. It becomes difficult to point out the causative agent among the multitude of drugs. Hence, a detailed history of drug intake in cases of acute pancreatitis may help to identify the candidature of the drugs in the pathogenesis of the disease. In view of the increasing illicit and medical use of cannabis, it becomes quintessential for clinicians to consider pancreatitis as a possible adverse effect of cannabis.
