Situs inversus totalis (SIT) is a rare congenital anomaly that refers to a completely reversed location of the abdominal and thoracic organs. We report the case of 50-year-old man with gastric cancer and SIT who was diagnosed during a screening esophagogastroduodenoscopy. A chest X-ray, abdominopelvic computed tomography, and (18)F-fluoro2-deoxyglucose-D-glucose-positron emission tomography scans revealed SIT. We performed a radical subtotal gastrectomy with D2 lymph node dissection. Advanced surgical skill is required to perform a precise lymphadenectomy in a patient with SIT by visualizing the exact mirror image of the anatomy during the operation...

Although it has been reported that endoscopic double stenting using a self-expandable metallic stent (SEMS) for gastroduodenal and biliary obstruction is useful [1-2], the efficacy and safety of performing double stenting using balloon enteroscopy is uncertain in patients with surgically altered anatomy. We describe a patient who had undergone gastrectomy and then underwent endoscopic double stenting for gastrojejunostomy anastomotic and biliary obstruction. A man in his 50s with a history of having undergone distal gastrectomy with Roux-en-Y reconstruction because of gastric cancer developed gastrojejunostomy anastomotic obstruction due to local anastomotic recurrence and peritoneal dissemination (Fig...

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and one of the major reasons for performing percutaneous endovascular procedures or liver surgery. Hepatic arterial anatomy is of major importance in performing these procedures on the liver. The aim of our study was to estimate the prevalence of various hepatic arterial variants in HCC patients. 78 patients were included in the study. Abdominal multiphase Computed Tomography scans of all patients have been assessed for presence of the hepatic arterial supply anatomical variations...

Oesophageal anastomotic leak and fistula are major and life-threatening complications of oesophagectomy with resultant increased mortality. Non-operative approach of such cases should be the initial strategy. Re-operative surgery and/or stent insertion are considered if conservative measures failed. Although oesophageal stenting is a safe option for the leaks, stent migration and failure to completely cover large anastomotic leaks are the main complications and pitfalls of the procedure. These can be overcome by using multiple or larger stents...

PURPOSE: To evaluate the feasibility of real-time, real-anatomy tracking and gating for gastric lymphoma patients treated with magnetic resonance image-guided radiation therapy (MR-IGRT) METHODS: Over the last 2 years, 8 patients with gastric lymphoma were treated with 0.3-T, Co-60 MR-IGRT. Post-treatment analysis of real-time cine imaging in the sagittal plane during each patient's treatment revealed significant motion of the stomach. While this motion was accounted for with generous PTV margins, the system's capability for real-time, real-anatomy tracking could be used to reduce treatment margins by gating...

PURPOSE: Radiotherapy for gastric and gastroesophageal junction (GEJ) tumors commonly requires large margins due to deformation, motion and variable changes of the stomach anatomy, at the risk of increased normal tissue toxicities. This work quantifies the interfraction variation of stomach deformation from daily MRI-guided radiotherapy to allow for a more targeted determination of margin expansion in the treatment of gastric and GEJ tumors. METHODS: Five patients treated for gastric (n=3) and gastroesophageal junction (n=2) cancers with conventionally fractionated radiotherapy underwent daily MR imaging on a clinical MR-IGRT system...

By virtue of their cardiovascular anatomy, reptiles and amphibians can shunt blood away from the pulmonary or systemic circuits, but the functional role of this characteristic trait remains unclear. It has been suggested that right-to-left (R-L) shunt (recirculation of systemic blood within the body) fuels the gastric mucosa with acidified and CO2-rich blood to facilitate gastric acid secretion during digestion. However, in addition to elevating PCO2, R-L shunt also reduces arterial O2 levels and would compromise O2 delivery during the increased metabolic state of digestion...

OBJECTIVE: To determine the diagnostic efficiency of oral contrast-enhanced gastric ultrasonography in the evaluation of gastric lesions, based on large-scale multicenter study. METHODS: The study enrolled 383,945 patients with suspect gastric lesions who underwent complete oral contrast-enhanced gastric ultrasonography and endoscopic evaluation. Two operators, unaware of the results of other diagnostic procedures, performed each examination independently. The accuracies of conventional ultrasonography, oral contrast-enhanced gastric ultrasonography, and upper gastrointestinal endoscopy were determined...

Gastric variceal bleeding is a major complication of portal hypertension and is associated with high morbidity and mortality. While esophageal varices are more common, gastric varices are often more challenging to treat. Balloon-Occluded Retrograde Transvenous Obliteration is an interventional procedure whereby the portosystemic gastrorenal shunt is accessed via the left renal vein and the gastric varix outflow tract obliterated using direct sclerotherapy. Herein, we present a case of a 68-year-old female patient with cirrhosis who presented with bleeding gastric varices and successfully treated...

BACKGROUND: Morbid obesity remains one of society's significant medical dilemmas. It is rapidly worsening and expected to affect 35% of the US population by the year 2020. Common current bariatric procedures exist and include, but not limited to, the adjustable gastric band, gastric bypass, and the sleeve gastrectomy. Although beneficial to morbidly obese patients, they also alter the patient's anatomy and involve resections, or require maintenance. The goal of the trial is to show a new minimally invasive vertical gastric clip technique that produces significant weight loss but requires no resection, no change in anatomy, and is reversible...

BACKGROUND: Roux-en-Y gastric bypass surgery is widely applied to ameliorate morbid obesity, including diabetes in people with type 2 diabetes. The latter vanish a few days after surgery for many, but not in all patients before any weight reduction has occurred. The explanation for this change in metabolic status is poorly understood, but the observation may suggest that the fate obesity and diabetes is only partly linked after surgery. METHODS: The trajectories of weight reduction measured as reduced body mass index (BMI) in 741obese subjects with and without diabetes were evaluated...

Comparative efforts to understand the body plan evolution of stalked jellyfishes are scarce. Most characters, and particularly internal anatomy, have neither been explored for the class Staurozoa, nor broadly applied in its taxonomy and classification. Recently, a molecular phylogenetic hypothesis was derived for Staurozoa, allowing for the first broad histological comparative study of staurozoan taxa. This study uses comparative histology to describe the body plans of nine staurozoan species, inferring functional and evolutionary aspects of internal morphology based on the current phylogeny of Staurozoa...

Bariatric surgery (e.g. Roux-en-Y gastric bypass (RYGB)) has proven the most effective way of achieving sustainable weight losses and remission of type 2 diabetes (T2D). Studies indicate that the effectiveness of RYGB is mediated by an altered gastrointestinal tract anatomy, which in particular favours release of the gut incretin hormone glucagon-like peptide-1 (GLP-1). The EndoBarrier gastrointestinal liner or duodenal-jejunal bypass sleeve (DJBS) is an endoscopic deployable minimally invasive and fully reversible technique designed to mimic the bypass component of the RYGB...

BACKGROUND: The anatomical and physiological changes after Roux-en-Y gastric bypass for morbid obesity can lead to severe hyperinsulinemic hypoglycemia with neuroglycopenia in a small percentage of patients. The exact physiologic mechanism is not completely understood. Surgical reversal to the original anatomy and distal or total pancreatectomy are current therapeutic options to reverse the hypoglycemic effect, with substantial associated morbidity. Our group reports a pilot clinical series of a novel surgical technique using one-anastomosis jejunal interposition with gastric remnant resection (Branco-Zorron Switch)...

Background and study aims: Endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD) is potentially complicated by bile leak and stent migration. The aim of this study was to evaluate the safety and effectiveness of a long (≥ 10 cm), partially covered metal stent (LP-CMS) for EUS-guided hepaticogastrostomy (EUS-HGS) for malignant biliary obstruction. Both the stent length and the uncovered portion at the proximal end of the LP-CMS are designed to prevent stent migration. Patients and methods: A total of 33 patients undergoing EUS-HGS using an LP-CMS in four centers were retrospectively studied...

REVIEW
Brian Badgwell
Surgical resection is the primary method of obtaining a potential cure for patients with gastric adenocarcinoma. However, chemotherapy or chemoradiotherapy offer significant improvement in survival over surgery alone. Much of the difficulty in deciding the optimal treatment strategy is choosing between perioperative chemotherapy or adjuvant chemoradiotherapy. Adding to the complexity is the potential for incorporating treatment strategies based on clinical trials performed in Asia. There is likely a difference in tumor biology between Eastern and Western patients with gastric adenocarcinoma, in addition to the clear differences in screening, pathologic assessment, and surgical technique...

Background: Roux-en-Y gastric bypass (RYGB) is a standard therapy in bariatric surgery. Sleeve gastrectomy and gastric banding, although with good results in the literature, are showing higher rates of treatment failure to reduce obesity-associated morbidity and body weight. Other problems after bariatric may occur, as band erosion, gastroesophageal reflux disease and might be refractory to medication. Therefore, a laparoscopic conversion to a RYGB can be an effective alternative, as long as specific indications for revision are fulfilled...
