A 57-year-old woman with history of hypercholesterolemia and situs inversus totalis presented a chief complaint epigastric pain poor appetite for 2 days. The was 7/10 in intensity no radiation. On physical examination, she had abdominal scars but there evidence hepatosplenomegaly tenderness on palpation, although Murphy's sign negative; bowel sounds were normal auscultation. results laboratory testing revealed aspartate transaminase (AST) alanine (ALT) levels, an elevated total bilirubin 1.3...
A 60-year-old woman with mitral valve prolapse, chronic low back pain, and a 30-pack year smoking history presented for second admission of poorly controlled mid-back pain 10 days after her first admission. She had concomitant epigastric sharp/burning in quality, radiating to the right side mid-back, not associated food nor improving medications. denied nausea, vomiting, diarrhea, constipation, dark stools, or blood per rectum. Our purpose was determine cause patient's pain. Physical...
Purpose: POEM is the first NOTES procedure that appears poised to replace its surgical counterpart, Heller myotomy. In 2009, we performed outside of Japan and worldwide by a gastroenterologist. This study reports outcomes from our 4-year prospective series with mean follow-up 12.5 months. largest single operator gastroenterologist worldwide, likely number post patients (pts) assessed objective tests for emptying reflux, large proportion challenging pts. Methods: Prospective IRB including...
Short bowel syndrome (SBS) is characterized by severely reduced functional intestinal length: <150–200 cm of post-duodenal small intestine.1 Due to diminished absorptive capacity from length, conventional diet does not always adequately provide nutrition for short patients. Consequently, many patients rely on total parenteral nutrition. These often experience failure (IF), which has been defined as “loss the inability maintain proper hydration or protein energy, electrolyte, micronutrient...
Roux-en-Y gastric bypass (RYGB) is a highly effective surgical approach for the treatment of morbid obesity [1]. Postsurgical bleeding leading to intraluminal blood clot formation causes outlet obstruction (GOO) at site anastomosis, and typically managed by laparotomy or revision [1] [2]. Gastrojejunal clots causing GOO following laparoscopic RYGB occur in 3 % – 27 patients Endoscopic dilation gastrojejunal provides an alternative revision, but symptomatic relief may require up three...
Small bowel transplantation (SBT) is a therapeutic option for those patients who suffer from short syndrome, intestinal failure, and life-threatening complications related to total parental nutrition (TPN). Post-small transplant rejection continues be major cause of morbidity mortality. Endoscopically, graft characterized by hemorrhage, blunting, sloughing the villi while histologically, it increased apoptotic bodies decreased mitotic per crypt. Teduglutide, glucagon-like peptide 2 analogue,...
Introduction: Most UGI SETs are GISTs, potentially malignant tumors. Many guidelines recommend surgery for suspected GISTs ≥2 cm and endoscopic surveillance of those <2 cm. This approach creates a large burden endoscopy small the majority which low-risk. situation motivated endoscopists, mostly from Asia, to use ESD “enucleate” muscularis propria (MP) based SETs. However, such enucleation may leave microscopic residual tumor within MP. Recently, pioneering Asian centers reported two...
Introduction: POEM represents a groundbreaking natural orifice transluminal endoscopic surgery (NOTES) approach to lower esophageal sphincter (LES) myotomy that combines the long-term benefits of surgical with advantages less invasive, intervention. In 2009, we performed first outside Japan and worldwide by gastroenterologist currently have largest single operator series worldwide. The aim this study is report outcomes achalasia patients treated in tertiary referral center. Methods: Between...
Introduction: An 89-year-old woman with GERD and hypothyroidism presented a 7-month history of dysphagia odynophagia to both solids liquids. She was admitted 1 month prior this admission for similar symptoms underwent an EGD, which revealed hiatal hernia. Despite compliance omeprazole 40 mg daily, she returned the emergency room worsening symptoms. denied abdominal pain, nausea, vomiting, diarrhea, constipation, dark stools, blood per rectum, or jaundice. Physical exam elongated face...

Purpose: A 60-year-old woman with past medical history of mitral valve prolapse, chronic low back pain and a 30 packs-a-year smoking presented for second admission poorlycontrolled mid-back 10 days after her first admission. She had concomitant epigastric pain, which was sharp/burning in quality, radiating to the right side not associated food, nor did it improve medications. denied nausea, vomiting, diarrhea, constipation, dark stools or blood per rectum. Physical examination revealed...
Purpose: One of the most frequent surgical modalities for treatment obesity is Roux-en-Y gastric bypass (RYGB). Previously described complications RYGB include stomal stenosis, staple line dehiscence, leaks, jejunal and wall necrosis, loculated fluid collections. Another reported complication post-operative intraluminal bleeding, which usually self-limiting. However, it uncommon to encounter early outlet obstruction secondary blood clots. Intraluminal clot formation causing post has been in...
Introduction: The following case report describes a patient with known medical history of AL Amyloidosis previously treated Autologous Stem Cell Transplant (ASCT) presenting chronic diarrhea, weakness and progressively worsening lower extremity swelling. Workup revealed protein losing enteropathy secondary to GI found via EGD duodenal biopsy. This is unique because most patients amyloid deposition in the tract present constipation, mechanical obstruction or intestinal whereas our presented...
Despite the fact that 15 - 25% of patients are colonized with Clostridium Difficile(CD) after a hospital admission or course antibiotics, CD bacteremia and extra-intestinal manifestations remain rare. Herein we present unique case large liver abscess related to in an otherwise healthy individual absence colitis. A 43-year-old Hispanic male no previous medical problems presented one week fevers right upper quadrant abdominal pain. The patient denies having diarrhea recent antibiotic use. On...
