ABSTRACT
Background and Aims: Endoscopic sleeve gastroplasty (ESG) is a minimally invasive bariatric procedure to induce weight loss through restrictive physiology. This study was designed to evaluate the fluoroscopic measurement of gastric dimensions after ESG as a predictor of Total Body Weight Loss (TBWL) over time. Methods: Post-ESG patients were enrolled prospectively between August 2013 and August 2019. An upper gastrointestinal (GI) fluoroscopy was obtained within 7 days after the procedure. Two blinded, independent radiologists reviewed fluoroscopic images and measured the gastric lumen transverse diameter in three separate areas of the fundus, body, and antrum. The primary outcome was achieving a TBWL of ten percent or more after ESG. Results: In total, 162 patients were included in the analysis (65% female) and had a mean body mass index (BMI) of 39 ± 6 at baseline. Patients had a mean maximum TBWL of 16.5 ± 8.3%. Respectively, 92%, 75%, and 50% of patients achieved a TBWL of 5%, 10%, or 15% or more. The mean post-procedural UGI gastric fundus/antrum transverse measurement ratio was 1.2 ± 0.6. A higher fundus-to-antrum ratio was significantly associated with a TBWL of 10% or more during follow-up in the multivariable model (OR 2.49, 95% CI 1.31-4.71; p-value 0.005). The prediction score based on the fundus-to-antrum ratio hd an area under the ROC curve of 0.79 (95% CI 0.75-0.83) for predicting a TBWL of 10% or more during follow-up. Conclusions: Measuring gastric the fundus/antrum ratio within one week of endoscopic sleeve gastroplasty (ESG) is a consistent and independent predictive measure of sustained TBWL during long-term follow-up.
ABSTRACT
Syphilis is a sexually transmitted disease that impacts multiple organ systems and can mimic various diseases and is an extremely rare cause of proctitis in men who have sex with men and transgender females. We present a case of a 49-year-old transgender female with a medical history significant for diabetes mellitus and hyperlipidemia who presented to the emergency department with dull abdominal pain in the left upper and lower quadrants for two days. She had non-bloody, nonbilious emesis, 10-pound weight loss over 1 month, and constipation for 2 weeks. Laboratory results showed a cholestatic pattern. Computed tomography of the abdomen showed rectal wall thickening, multiple enlarged perirectal adenopathy, and mild inflammatory infiltration around the rectum suggesting superimposed proctitis. On colonoscopy, a possible rectal mass or severe proctitis with near complete obstruction was seen with initial pathology concerning for lymphoma or a rare type of colitis. The patient was empirically started on ceftriaxone and doxycycline leading to improvement in inflammation. Special stains requested were positive for Treponema pallidum confirming the diagnosis of syphilitic proctitis and highly suggestive syphilitic hepatitis. Few cases of syphilitic proctitis imitating rectal malignancy and syphilitic hepatitis have been reported. Syphilis requires exclusion as well as confirmation of spirochetes for high-risk populations with special staining. It is important to diagnose syphilis in special populations that are at high risk of contraction.
ABSTRACT
Periampullary diverticula are outpouches in the mucosa in the duodenum surrounding the ampulla of Vater. Most cases of periampullary diverticuli are asymptomatic, but complications can arise, increasing a patient's mortality. Diagnosis of periampullary diverticuli is often incidental during endoscopy or imaging studies for abdominal pain. When a patient with periampullary diverticuli is symptomatic, imaging modalities such as CT scan and MRI can help make the diagnosis, but a side-viewing endoscope provides direct visualization of the diverticuli and also allows for the potential treatment of the disease. Lemmel's syndrome is a complication of periampullary diverticuli where the diverticuli causes mechanical obstruction of the bile duct leading to obstructive jaundice without choledocholithiasis. These patients are at risk for further complications such as sepsis and perforation. Early diagnosis and treatment of these patients can help to prevent further complications from arising. We are presenting a case of Lemmel's syndrome with obstructive jaundice from a periampullary diverticuli, further complicated by cholangitis without dilation of the biliary tree.
ABSTRACT
Lymphoma in the gastrointestinal tract most commonly occurs in the stomach, small intestine and around the ileocecal region. Usually gastrointestinal lymphoma occurs secondary to widespread nodal disease and is rarely found to be the primary site. Of the different types of lymphoma, diffuse large B-cell non-Hodgkin's lymphoma makes up the majority of lymphomas in the gastrointestinal tract. Primary colorectal lymphoma is even less common and accounts for 3% of all gastrointestinal lymphomas and to our knowledge, gastrointestinal lymphoma involving 2 different regions in the GI tract has not been discussed in the literature. Herein, we are presenting a rare case of diffuse large B-cell lymphoma presenting as a malignant mass in both the duodenum and ascending colon.
ABSTRACT
Mantle cell lymphoma (MCL), a type of B-cell non-Hodgkin's lymphoma, is a rare and aggressive disease with a poor prognosis due to its advanced presentation at diagnosis. It is characterized by a translocation in the Bcl-1 gene, which results in overexpression of cyclin D1. MCL is frequently seen in the form of multiple lymphomatous polyposis (MLP) in which innumerable polyps are observed in the gastrointestinal (GI) tract. In rare instances, MCL presents a single mass. The most common presentation involves male patients in their sixties, with generalized lymphadenopathy, extranodal involvement, and B symptoms (night sweats, fever, and weight loss). Endoscopic findings of MLP include cerebroid folding of the gastric mucosa and innumerable polyps extending from the duodenum to the large intestine and are reported in approximately 9% of all GI lymphomas. Less commonly, only 2-4% of GI malignancies present as a primary GI MCL as a single mass, usually in the stomach and ileocecal region in the intestine. Radiologic findings include lymphadenopathy, splenomegaly, multiple polyposis, or wall thickening with ulceration or mass formation. In most instances, advanced disease is found at diagnosis, for which 5-year survival ranges only from 26 to 46%, even when appropriate treatment is initiated. High mitotic rate, or Ki-67 index, is of prognostic value and is associated with poor prognosis. Treatment involves conventional chemo-immunotherapy consisting of R CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) or RB (rituximab and bendamustine), with the latter being better tolerated and associated with longer progression-free survival. Surgical resection is usually limited to patients in which complications are seen such as bleeding, perforation, or bowel obstruction. We present a unique case of a 70-year-old male with nonbilious, nonbloody emesis, and symptomatic anemia who was found to have a cecal mass consistent with MCL.
ABSTRACT
Heterotopic pancreas (HP) is a congenital abnormality that represents ectopic pancreatic tissue that does not have anatomic, vascular, or ductal continuity. The prevalence of HP is 0.55% to 13.7% on autopsy, 0.2% to 0.5% of abdominal operations, and 0.9% of gastrectomies. It is commonly found in the stomach, duodenum, and proximal jejunum. Only 15 cases have been reported in the medical literature regarding involvement of the esophagus. Treatment depends on symptoms and location. In asymptomatic patients, simple observation may be sufficient; however, in those who are symptomatic, surgery may be warranted. We present a case of a 70-year-old male with heartburn, nausea, and abdominal bloating who underwent a diagnostic esophagogastroduodenoscopy (EGD) and was found to have HP on histology in the distal esophagus. In our case, symptoms were treated conservatively and successfully with a proton pump inhibitor (PPI).
ABSTRACT
Thyrotoxic periodic paralysis (TPP) is a potentially fatal complication of hyperthyroidism, characterized by recurrent muscle paralysis and hypokalemia. We present a case of a 32-year-old apparently healthy male patient, who presented with acute paraparesis associated with hypokalemia (K: 1.6 mmol/L), complicated by ventricular tachycardia (VT). Advanced cardiac life support was initiated with an amiodarone infusion, and eventually QRS complex narrowed and wide complex tachycardia resolved. Intravenous potassium chloride (KCl) 40 mEq over 2-3 h and oral KCL 40 mEq were administered to treat the electrolyte imbalance. Patient paralysis was quickly reversed; motor function was regained with movement of the lower extremities. This case highlights the importance of early recognition and prompt treatment of TPP as a differential diagnosis for muscle weakness, especially in the setting of severe hypokalemia. It is important to pay attention to the possibility of the development of lethal VT associated with hypokalemia in the setting of hyperthyroidism and thyrotoxic paralysis.
ABSTRACT
The present case is unique because it describes transcatheter mitral valve replacement with a valve-in-valve procedure in an emergent setting of pulmonary edema and cardiogenic shock. Although transcatheter mitral valve replacement is in its initial phase, it remains a viable option in an emergency. Further research is needed to evaluate the short term and long-term outcomes.
