Effect of a blend of magnesium oxide on Equine Squamous Gastric Disease in young trotter horses under training.

BACKGROUND: Equine squamous gastric disease (ESGD), as part of the equine gastric ulcer syndrome (EGUS), are common in racing horses. The use of buffering feed supplements to treat and/or prevent gastric ulcers is an option to control this condition. OBJECTIVE: The purpose of this study was to evaluate the effect of a 30-day supplementation with a blend of magnesium oxide (MgO) on ESGD scores in trotters under training. METHODS: Forty-two young trotters were submitted to a gastroscopic evaluation to assess their ESGD score and were randomly assigned in a group supplemented with MgO or in a control group. After 30 days, a second evaluation by gastroscopy was performed. The effect of the MgO supplementation was assessed by comparing the evolution of the ESGD score in supplemented and control groups between day 0 and day 30. RESULTS: The results confirm the high prevalence of EGUS in young Trotters. The supplementation significantly decreased the ESGD scoring in the supplemented group whereas the control group remain unchanged. CONCLUSION: The oral MgO supplementation was efficient to control ESGD in the population studied.

The T stage of esophageal cancer can be effectively predicted by muscularis propria thickness and muscularis propria + mucosa thickness under ultrasonic gastroscopy.

OBJECTIVES: The latest version of the National Comprehensive Cancer Network recommends neoadjuvant therapy followed by surgical treatment or radical chemoradiotherapy for patients with cT3N0M0. Neoadjuvant therapy can improve the prognosis of patients with locally advanced esophageal cancer. Therefore, the evaluation or prediction of T stage is particularly important because the treatment could differently affect the prognosis. Here, we establish a model to predict the T stage of patients with T2-3N0M0 to help choose the best treatment strategy. METHODS: From 1637 patents with esophageal cancer, we enrolled 48 patients and performed least absolute shrinkage and selection operator regression to screen for independent factors influencing pathological T stage. We, then, trained the decision tree to obtain the decision tree diagram and divided the T stages obtained by different methods into two categories, T2 and T3, for survival analysis. RESULTS: A total of 21 and 27 cases were predicted to be T2 and T3, respectively, under ultrasonic gastroscopy, 19 and 29 under magnetic resonance imaging, and 22 and 26 under pathological examination. Multivariate logistic regression analysis revealed that the muscularis propria thickness (MPT) (p = 0.0097) and the muscularis propria + mucosa thickness (MPMT) in the largest tumor cross-section (p = 0.0239) were independent influencing factors. We plotted a decision tree diagram with these two factors. MPT in the largest tumor cross-section >1.3 mm could be judged as pT3; if ≤1.3 mm, MPMT should be considered a thickness ≥1.7 mm could be judged as pT2 (otherwise pT3). Corresponding survival analysis was performed according to the T stage under different examination modalities. CONCLUSION: MPT in the largest tumor cross-section and MPMT in the largest tumor cross-section are independent predicting factors of pathological T stage.

Gastric Cancer Screening in First-Degree Relatives: A Pilot Study in a Diverse Integrated Healthcare System.

INTRODUCTION: Family history of gastric cancer has been shown as an independent risk factor of gastric cancer development and is associated with increased risk of progression to gastric cancer among patients with gastric intestinal metaplasia (GIM). METHODS: Between 2017 and 2020, we conducted a prospective pilot screening program of patients with a confirmed first-degree relative with gastric cancer to evaluate the feasibility of screening and prevalence of precursor lesions (e.g., GIM or dysplasia) on biopsy. RESULTS: A total of 61 patients completed screening by upper endoscopy with a mapping biopsy protocol: 27 (44%) were found to have GIM and 4 (7%) were found with low-grade dysplasia. DISCUSSION: Our pilot screening program identified a high prevalence of precursor lesions for gastric cancer among asymptomatic patients with a first-degree relative with gastric cancer. Careful endoscopic inspection and standardized biopsy protocols may aid in prompt identification of these precursor lesions in those at risk of gastric cancer.

Development and Characterization of A New Dimethicone Nanoemulsion and its Application for Electronic Gastroscopy Examination.

PURPOSE: Although the effective and safe medical defoamers, dimethicone (DM) and simethicone (SM) are widely used in electronic gastroscope examination (EGE), their preparations are presented in the form of suspensions or emulsions, these are untransparent or milk-like in appearance and can easily cause misdiagnosis as a result of an unclear field of vision if the doctor does not master the amount of defoamer or operates incorrectly. At the same time, it is also difficult to wash out the camera and pipeline, due to the large oil droplets of preparations. The purpose of this study was to develop a new clear and transparent oil in water (O/W) DM nanoemulsions (DMNs) and observe the effect of application in EGE. METHODS: The oil phase was chosen for its antifoaming activity and viscosity. The emulsifier and co-emulsifier were selected according to the solubility of the oil phase in them. The water titration method was used to make the pseudoternary phase diagrams of nanoemulsions and optimize the prescription composition. DM-in-water nanoemulsion was prepared by the low energy method and evaluated for appearance, antifoaming ability, droplet size, and stability. The effect of DMNs utilized in EGEs was also observed. RESULTS: The optimal formulation of DMNs contained CRH-40 as an emulsifier, PEG-400 as a co-emulsifier, DM as oil phase with the viscosity of 10 mPa.s, and their proportion was 4.5:4.5:1, respectively. DMNs obtained the average particle size of 67.98 nm with the polydispersity index (PDI) of 0.332, and 57.14% defoaming rate. The result of using an EGE showed that DMNs were superior in comparison to the emulsions with regard to the defoaming effect, visual clarity, and easy cleanup. CONCLUSION: DMNs were found to provide excellent visual clarity to its other preparations. The novel DMNs is a promising substitute for DM emulsions or suspensions in EGEs.

Association Between Lifestyle Factors, Vitamin and Garlic Supplementation, and Gastric Cancer Outcomes: A Secondary Analysis of a Randomized Clinical Trial.

Importance: The associations of lifestyle factors with gastric cancer (GC) are still underexplored in populations in China. Long-term nutritional supplementation may prevent GC in high-risk populations, but the possible effect modification by lifestyle factors remains unknown. Objective: To evaluate how lifestyle factors, including smoking, alcohol intake, and diet, may change the risk of GC incidence and mortality and whether the effects of vitamin and garlic supplementation on GC are associated with major lifestyle factors. Design, Setting, and Participants: This is a secondary analysis of the Shandong Intervention Trial, a masked, randomized, placebo-controlled trial that aimed to assess the effect of vitamin and garlic supplementations and Helicobacter pylori treatment on GC in a factorial design with 22.3 years of follow-up. The study took place in Linqu County, Shandong province, China, a high-risk area for GC. Data were collected from Jully 1995 to December 2017. Overall, 3365 participants aged 35 to 64 years identified in 13 randomly selected villages who agreed to undergo gastroscopy were invited to participate in the trial and were included in the analysis. Data analysis was conducted from March to May 2019. Interventions: Participants received vitamin and garlic supplementation for 7.3 years, H pylori treatment for 2 weeks (among participants with H pylori ), or placebo. Main Outcomes and Measures: The primary outcomes were GC incidence and GC mortality (1995-2017). We also examined the progression of gastric lesions (1995-2003) as a secondary outcome. Results: Of the 3365 participants (mean [SD] age, 47.1 [9.2] years; 1639 [48.7%] women), 1677 (49.8%) were randomized to receive active vitamin supplementation, with 1688 (50.2%) receiving placebo, and 1678 (49.9%) receiving active garlic supplementation, with 1687 (50.1%) receiving placebo. Overall, 151 GC cases (4.5%) and 94 GC deaths (2.8%) were identified. Smoking was associated with increased risk of GC incidence (odds ratio, 1.72; 95% CI, 1.003-2.93) and mortality (hazard ratio [HR], 2.01; 95% CI, 1.01-3.98). Smoking was not associated with changes to the effects of vitamin or garlic supplementation. The protective effect on GC mortality associated with garlic supplementation was observed only among those not drinking alcohol (never drank alcohol: HR, 0.33; 95% CI, 0.15-0.75; ever drank alcohol: HR, 0.92; 95% CI, 0.55-1.54; P for interaction = .03), and significant interactions were only seen among participants with H pylori (never drank alcohol: HR, 0.31; 95% CI, 0.12-0.78; ever drank alcohol: HR, 0.91; 95% CI, 0.52-1.60; P for interaction = .04). No significant interactions between vitamin supplementation and lifestyle factors were found. Conclusions and Relevance: In this secondary analysis of a randomized clinical trial, smoking was associated with an increased risk of GC incidence and mortality. Not drinking alcohol was associated with a stronger beneficial effect of garlic supplementation on GC prevention. Our findings provide new insights into lifestyle intervention for GC prevention, suggesting that mass GC prevention strategies may need to be tailored to specific population subgroups to maximize the potential beneficial effect.

Effects of audio and visual distraction on patients' vital signs and tolerance during esophagogastroduodenoscopy: a randomized controlled trial.

BACKGROUND: Esophagogastroduodenoscopy (EGD) provides an indispensable and unambiguous inspection allowing the discovery upper gastrointestinal lesions. However, many patients are anxious about undergoing EGD. Few studies have investigated the influence on patients' vital signs and tolerance during EGD using subjective and objective assessments. This study was a prospective randomized controlled study that investigated the influence of audio and visual distraction on EGD. METHODS: We randomly divided 289 subjects who underwent EGD into 4 groups (control group, audio group, visual group, combination group) and examined their vital signs, heart rate variability (HRV), psychological items, and acceptance of distraction. RESULTS: Pulse rate (PR) at post-distraction and post-EGD in the 3 distraction groups were significantly lower than those of control group (p <  0.001 and p <  0.01, respectively). Blood pressure (BP) during and post-EGD was significantly higher than that at pre-EGD in control group (p <  0.05), but no significant elevation of BP was observed during the latter half of EGD and post-EGD in the 3 distraction groups. BP at post-distraction improved significantly compared to pre-distraction in the 3 distraction groups (p <  0.05). There was a significant difference in the low-frequency (LF) power/ high-frequency (HF) power at post-distraction and post-EGD among the 4 groups (p <  0.001 and p <  0.001, respectively). The LF power/HF power at post-distraction and post-EGD in the 3 distraction groups was significantly lower than that in control group (p <  0.05). Several items of profile of mood states (POMS) and the impression of EGD at post-distraction improved significantly compared to those at pre-distraction among the 3 distraction groups (p <  0.05). Visual analog scale (VAS) of willingness for the next use of distraction in the 3 distraction groups was excellent because VAS was more than 70. CONCLUSIONS: Distractions effectively improved psychological factors, vital signs and some of HRV at pre and post-EGD. Distractions may suppress BP elevation during the latter half of EGD and lead to stability of HRV on EGD. TRIAL REGISTRATION: This prospective trial was registered in the University Hospital Medical Information Network (UMIN) Clinical Trials Registry as UMIN000029637. Registered on 20 October 2017.

The recurrent bleeding risk of a Forrest IIc lesion at the second-look endoscopy can be indicated by high Rockall scores ≥ 6.

BACKGROUND: The Forrest classification is widely applied to guide endoscopic hemostasis for peptic ulcer bleeding. Accordingly, practice guidelines suggest medical treatment only for ulcer with a Forrest IIc lesion because it has low rebleeding risk even without endoscopic therapy, ranging from 0 to 13%. However, the risk ranges widely and it is unclear who is at risk of rebleeding with such a lesion. This study assessed whether the Rockall score, which evaluates patients holistically, could indicate the risk of recurrent bleeding among patients with a Forrest IIc lesion at the second-look endoscopy. METHODS: Patients who had peptic ulcer bleeding with Ia-IIb lesions received endoscopic hemostasis at the primary endoscopy, and they were enrolled if their Ia-IIb lesions had been fading to IIc at the second-look endoscopy after 48- to 72-h intravenous proton pump inhibitor (PPI) infusion. Primary outcomes were rebleeding during the 4th-14th day and 4th-28th day after the first bleeding episode. RESULTS: The prospective cohort study enrolled 140 patients, who were divided into a Rockall scores ≥ 6 group or a Rockall scores < 6 group. The rebleeding rates in the Rockall scores ≥ 6 group and the Rockall scores < 6 group during the 4th-14th day and the 4th-28th day were 13/70 (18.6%) versus 2/70 (2.9%), p = 0.003 and 17/70 (24.3%) versus 3/70 (4.3%), p = 0.001, respectively, based on an intention-to-treat analysis and 5/62 (8.1%) versus 0/68 (0%), p = 0.023 and 6/59 (10.2%) versus 0/67 (0%), p = 0.009, respectively, based on a per-protocol analysis. The Kaplan-Meier curves showed that the Rockall scores ≥ 6 group had a significantly lower cumulative rebleeding-free proportion than the Rockall scores < 6 group (p = 0.01). CONCLUSIONS: Combined Rockall scores ≥ 6 on arrival with a Forrest IIc lesion at the second-look endoscopy can identify patients at risk of recurrent peptic ulcer bleeding following initial endoscopic and intravenous PPI treatment.

Updated evaluation of endoscopic submucosal dissection versus surgery for early gastric cancer: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Endoscopic resection (ER) has been a standard treatment modality for early gastric cancer with ignorable risks of lymph node metastasis. As for EGCs within expanded indications, endoscopic submucosal dissection (ESD) has considerable advantages over endoscopic mucosal resection (EMR) regarding higher rate of en bloc resection, complete resection, but lower risk of local recurrence. Previous meta-analyses comparing ESD with surgery for EGC are scarce and not robust to reach definitive conclusions. METHODS: We searched PubMed, Web of Science, EMBASE, Cochrane Library Databases and Google Scholar through July 2019 to identify studies evaluating ESD vs surgery for EGC. Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of enrolled studies. Patient baseline characteristics, procedure-related and prognosis outcomes, and adverse event data were extracted and pooled for analyses by the Review Manager 5.3 software. Grading of Recommendations Assessment, Development and Evaluation guidelines (GRADE) were used to assess the quality of evidence. Trial Sequential Analysis (TSA) was conducted to weaken random error and enhance the reliability of evidence. RESULTS: Totally 18 retrospective studies, involving 5993 patients, were included. ESD benefits were 128.38 min shorter operation duration [95%CI: (-204.68, -52.09), P = 0.001], 7.13 days shorter hospital stay [95%CI: (-7.98, -6.28), P < 0.00001], lower risk of procedure-related death [OR = 0.21, 95%CI: (0.07, 0.68), P = 0.009], lower risk of overall complication [OR = 0.47, 95%CI: (0.34, 0.63), P < 0.00001]. ESD was also associated with lower costs and better quality of life. However, ESD had lower rate of en bloc resection [OR = 0.07, 95%CI: (0.03, 0.21), P < 0.00001], histologically complete resection [OR = 0.07, 95%CI: (0.03, 0.14), P < 0.00001], curative resection [OR = 0.06, 95%CI: (0.01, 0.27), P = 0.002], and higher rate of local recurrence [OR = 5.42, 95%CI: (2.91, 10.11), P < 0.00001], metachronous cancer [OR = 10.84, 95%CI: (6.43, 18.26), P < 0.00001], synchronous cancer [OR = 6.59, 95%CI: (1.96, 22.1), P = 0.002]. ESD also led to lower disease-free survival [HR = 4.58, 95%CI: (2.79, 7.52), P < 0.00001] and recurrence-free survival [HR = 1.99, 95%CI: (1.38, 2.87), P = 0.0002]. No significant differences in overall survival (OS) and disease-specific survival (DSS) between ESD and surgery were observed. CONCLUSIONS: ESD offers a method of less expensive, less trauma, faster recovery and better quality of life compared to surgery for EGC. However, ESD is associated with higher risk of recurrence without compromising OS and DSS. Strict and careful surveillance after ESD is needed. Recurrent EGCs following ESD can usually be detected in early stage and successfully managed by repeated ESD. Accordingly, ESD technique provides an alternative to surgical resection for highly selected EGC patients.

Unsedated Outpatient Percutaneous Endoscopic Gastrostomy in Stroke Patients: Is It Feasible and Safe?

Percutaneous endoscopic gastrostomy (PEG) is an established practice for long-term nutrition in dysphagia-suffering stroke patients. This study sought to determine the feasibility and safety of outpatient, unsedated PEG implementation in stroke patients. This retrospective cohort study involved stroke victims who underwent unsedated outpatient PEG insertion from 2014 to 2017 at our Surgical Endoscopy Unit. Patients were given pharyngeal anesthesia with lidocaine 10% spray, while the PEG tube was placed under local anesthesia. The incidence of intraprocedural and postprocedural complications and 30-day mortality rate were recorded. Data from 127 cases were analyzed. The procedures were performed with minor, transient complications, which resolved after rescue maneuvers. No intraprocedural and postprocedural major complications or death were observed. During the 30-day follow-up, the most important complication involved a single case of accidental PEG removal that was successfully resolved surgically. Unsedated PEG insertion appears to be a feasible, well-tolerated, and safe option for stroke-related dysphagia.

Effects of Early Initiation of Solid Versus Liquid Diet after Endoscopic Submucosal Dissection on Quality of Life and Postoperative Outcomes: A Prospective Pilot Randomized Controlled Trial.

BACKGROUND/AIMS: Feeding recommendations after endoscopic submucosal dissection (ESD) for gastric neoplasms are not established and based on clinical experience. METHODS: This was a prospective pilot randomized controlled trial. Patients undergoing ESD for gastric neoplasms were randomly assigned to solid (n = 50) or liquid diet (n = 50) groups. Beginning the day after hemostasis confirmation until discharge, the solid diet group started on a diet of rice porridge, whereas the liquid diet group started on a liquid diet, with gradual transition to solid food. The primary endpoint was delayed bleeding rate. The secondary endpoints were quality of life (QOL), ulcer-stage, hospital fees, and post-ESD symptoms. RESULTS: Delayed bleeding occurred in the solid diet group (2%) but not in the liquid diet group. The QOL evaluation using European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-STO22 showed better score in the solid diet group. The patients who felt dietary restriction at discharge was of a larger number in the liquid diet group (p = 0.019). More patients experienced appetite loss (p = 0.038), constipation (p = 0.022), and dietary restriction (p = 0.037) in the liquid diet group during hospitalization. The other endpoints were equivalent between the groups. CONCLUSION: Early initiation of solid foods after ESD is feasible and associated with higher QOL, potentially rendering conventional liquid diets unnecessary, although additional studies are needed (Trial registration number: UMIN000013297).

A huge gastric bezoar treated by traditional Chinese medicine purgative: A case report.

RATIONALE: Currently, the mainstream treatment for gastric bezoars is endoscopic lithotripsy. This report describes traditional Chinese medicine (TCM) purgative cured a 62-year-old woman with a huge gastric bezoar accompanied by isolated esophageal venous aneurysms and multiple bleeding gastric ulcers. PATIENT CONCERNS: A 62-year-old woman with several symptoms, including epigastric pain, nausea, and vomiting, hiccups, heartburn, and dark, loose stools. The patient showed abdominal tenderness, positive Murphy sign, hyperactive bowel sounds, a pale tongue with scalloped edges, greasy moss, and pulse moisten. A complementary examination revealed the presence of occult blood in the vomit. DIAGNOSIS: The patient was diagnosed with isolated esophageal venous aneurysms, gastric bezoars, and multiple bleeding gastric ulcers. Gastroscopy revealed a 0.6 cm blue uplift, a smooth surface, and a regular and clearly defined dentate line. A large bezoar was observed in the stomach cavity with a dark red blood in the surface. The gastric angle showed multiple lesions, with their largest diameter being 2.5 cm, blood was oozing from these ulcers. INTERVENTIONS: The patient was prescribed a TCM purgative combined with omeprazole enteric-coated tablets. Three days after admission, the patient was diagnosed with isolated esophageal venous aneurysms, gastric bezoars, multiple bleeding gastric ulcers. A specific herbal formula was prescribed to eliminate the bezoar. In addition, conventional western medicine was used for the patient, such as pantoprazole sodium intravenous infusion to inhibit gastric acid and sodium bicarbonate solution orally to soften the gastric bezoar. OUTCOMES: After 5 days, the patient had complete relief from all remaining symptoms, including stomach pain and hiccups. Follow-up gastroscopy revealed that the venous aneurysm and gastric bezoar had disappeared, and the ulcer had reduced in size to approximately 0.6 to 0.8 cm. The patient was discharged after recovery and did not relapse for 3 years. LESSONS: TCM combined with conventional western medicine to treat huge gastric bezoars and its complications is effective and safe, and worth to be recommended as an alternative to endoscopic lithotripsy.

Surveillance for Gastric Cancer.

This article discusses the current National Comprehensive Cancer Network guidelines and other available Western and Eastern guidelines for the surveillance of gastric cancer following surgical resection. It reviews the literature assessing the utility of intensive surveillance strategies for gastric cancer, which fails to show an improvement in survival. The unique issues relating to follow-up of early gastric cancer and after endoscopic resection of early gastric cancer are discussed. This article also reviews the available modalities for follow-up. In addition, it briefly discusses the advancements in treatment of recurrent and metastatic disease and the implications for gastric cancer survival and surveillance strategies.

Cyanoacrylate therapy for the treatment of gastric varices: a new method.

OBJECTIVE: Cyanoacrylate (CYA) injection is recommended for bleeding gastric varices (GV) but with significant adverse effects. Transesophageal endoscopic ultrasound-guided therapy of large GV with a combined coil and CYA injection has shown promising results. However, it is expensive and requires technical expertise. In this study, we aimed to compare the safety and efficacy of a new method with UCYA [undiluated CYA (UCYA) followed by lipiodol-diluated CYA (DCYA)] in the management of large bleeding GV. METHODS: Fifteen consecutive patients with bleeding from large GV (>1 cm) were prospectively treated with DCYA and another 15 patients treated with UCYA retrospectively. All patients in the DCYA group underwent thoracic computed tomography scan to identify glue embolism. RESULTS: Baseline characteristics were similar between the two groups. Rates of GV obliteration and rebleeding were 100% vs 93.3% (P = 0.309) and 6.7% vs 33.3% (P = 0.06) in the DCYA and UCYA groups, respectively. One patient in the UCYA group had needle fixation which led to fatal bleeding after forceful needle extraction. In DCYA group none had glue embolism. CONCLUSIONS: Both UCYA and DCYA are effective in treating bleeding from large GV. DCYA has lower rebleeding rates and tends to have fewer adverse events than UCYA injection, although the differences are not statistically significant. Large-sample-sized prospective randomized trials are required.

Endoscopic treatment of gastroparesis.

Gastroparesis has traditionally been a largely medically managed disease with refractory symptoms typically falling under the umbrella of the surgical domain. Surgical options include, but are not limited to, gastrostomy, jejunostomy, pyloromyotomy, or pyloroplasty, and the Food and Drug Administration approved gastric electrical stimulation implantation. Endoscopic management of gastroparesis most commonly involves intrapyloric botulinum toxin injection; however, there exists a variety of endoscopic approaches on the horizon that have the potential to radically shift standard of care. Endoscopic management of gastroparesis seeks to treat delayed gastric emptying with a less invasive approach compared to the surgical approach. This review will serve to highlight such innovative and potentially transformative, endoscopic interventions available to gastroenterologists in the management of gastroparesis.

Diagnosis and treatment of unexplained anemia with iron deficiency without overt bleeding.

A general overview is given of the causes of anemia with iron deficiency as well as the pathogenesis of anemia and the para-clinical diagnosis of anemia. Anemia with iron deficiency but without overt GI bleeding is associated with a risk of malignant disease of the gastrointestinal tract; upper gastrointestinal cancer is 1/7 as common as colon cancer. Benign gastrointestinal causes of anemia are iron malabsorption (atrophic gastritis, celiac disease, chronic inflammation, and bariatric surgery) and chronic blood loss due to gastrointestinal ulcerations. The following diagnostic strategy is recommended for unexplained anemia with iron deficiency: conduct serological celiac disease screening with transglutaminase antibody (IgA type) and IgA testing and perform bidirectional endoscopy (gastroscopy and colonoscopy). Bidirectional endoscopy is not required in premenopausal women < 40 years of age. Small intestine investigation (capsule endoscopy, CT, or MRI enterography) is not recommended routinely after negative bidirectional endoscopy but should be conducted if there are red flags indicating malignant or inflammatory small bowel disease (e.g., involuntary weight loss, abdominal pain or increased CRP). Targeted treatment of any cause of anemia with iron deficiency found on diagnostic assessment should be initiated. In addition, iron supplementation should be administered, with the goal of normalizing hemoglobin levels and replenishing iron stores. Oral treatment with a 100-200 mg daily dose of elemental iron is recommended (lower dose if side effects), but 3-6 months of oral iron therapy is often required to achieve therapeutic goals. Intravenous iron therapy is used if oral treatment lacks efficacy or causes side effects or in the presence of intestinal malabsorption or prolonged inflammation. Three algorithms are given for the following conditions: a) the paraclinical diagnosis of anemia with iron deficiency; b) the diagnostic work-up for unexplained anemia with iron deficiency without overt bleeding; and c) how to proceed after negative bidirectional endoscopy of the gastrointestinal tract.

Treatment outcome for gastric mucosa-associated lymphoid tissue lymphoma according to Helicobacter pylori infection status: a single-center experience.

BACKGROUND/AIMS: Helicobacter pylori eradication therapy has been used as a first-line treatment for H. pylori-positive gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, the management strategy for H. pylori-negative MALT lymphoma remains controversial. Therefore, the aim of this study was to examine the success rate of each treatment option for H. pylori-positive and H. pylori-negative gastric MALT lymphomas. METHODS: In total, 57 patients with gastric MALT lymphoma diagnosed between December 2000 and June 2012 were enrolled in the study. The treatment responses were compared between H. pylori-positive and H. pylori-negative gastric MALT lymphomas. RESULTS: Of the 57 patients, 43 (75%) had H. pylori infection. Forty-eight patients received H. pylori eradication as a first-line treatment, and complete remission was achieved in 31 of the 39 patients (80%) with H. pylori-positive MALT lymphoma and in five (56%) of the nine patients with H. pylori-negative MALT lymphoma; no significant difference was observed between the groups (p=0.135). The other treatment modalities, including radiation therapy, chemotherapy, and surgery, were effective irrespective of H. pylori infection status, with no significant difference in the treatment response between H. pylori-positive and H. pylori-negative MALT lymphomas. CONCLUSIONS: H. pylori eradication therapy may be considered as a first-line treatment regardless of H. pylori infection status.

Safe intake of an oral supplement containing carbohydrates and whey protein shortly before sedation to gastroscopy; a double blind, randomized trial.

OBJECTIVE: To investigate the gastric emptying of an oral supplement containing carbohydrate plus whey protein drunk before sedation for gastroscopy. METHODS: This is a randomized double-blind trial including adult patients (ages 18-65) with a chief complaint of epigastric burning and who were candidates to elective gastroscopy. After overnight fast subjects were randomized to drink 200 mL of an oral nutritional supplement containing maltodextrine in addition to whey protein 150 to 210 min before the gastroscopy (intervention group, n = 12) or to undergo the endoscopic procedure with no supplement (control group, n = 12). The residual gastric volume (RGV) suctioned and measured during the exam was the main endpoint of the study. RESULTS: There were no complications during all exams. The median (range) fasting time was greater (P < 0.001) in control group (770 min, ranging from 660-917 min) than in the study group (175 min ranging from 150 to 210 min). The median (range) RGV was similar in between the two groups (control group: 25 (10-70) mL versus intervention group: 10 (0-100) mL; p = 0.32). CONCLUSION: Gastric emptying 150-210 min after the ingestion of an oral supplement containing carbohydrate plus whey protein is similar to an overnight fasting condition. Although limited by the number of cases, the sedation for endoscopic procedures is safe with this fasting protocol.

Objetivo: Investigar el vaciado gástrico de un suplemento oral que contiene hidratos de carbono, más proteínas de suero de leche tomado antes de la sedación para endoscopia. Método: Se trata de un estudio doble ciego aleatorizado, que incluyó pacientes adultos (18-65 años de edad) por presentar epigastralgia y que eran candidatos a gastroscopia electiva. Después de una noche de ayuno los pacientes fueron asignados aleatoriamente para tomar 200 ml de un suplemento nutricional oral que contiene maltodextrina y proteína de suero de leche, de 150 a 210 minutos antes de la sedación, para gastroscopia (grupo de intervención, n = 12) o continuar en ayuno para el procedimiento endoscópico (grupo control, n = 12). El volumen gástrico residual (RGV) aspirado y medido durante el examen fue la variable de evaluación principal del estudio. Resultados: No hubo complicaciones durante los exámenes. El tiempo medio de ayuno (rango) fue mayor (P.

[Efficacy of miniinvasive methods of diagnosis and treatment of gastric cancer, integrated in the endoscopic service organization].

The data, concerning the state of endoscopic service in Ukraine, were adduced. A modern approaches to the malignant tumors diagnosis, using high technologies, were depicted. There was summarized the experience of clinico-endoscopic peculiarities in studying of some malignant tumors forms and principles, constituting integral approach to treatment of such patients with participation of physicians-endoscopists and oncologists.

Approach to a child with upper gastrointestinal bleeding.

Upper gastrointestinal bleeding (UGIB) is a potentially life threatening medical emergency requiring an appropriate diagnostic and therapeutic approach. Therefore, the primary focus in a child with UGIB is resuscitation and stabilization followed by a diagnostic evaluation. The differential diagnosis of UGIB in children is determined by age and severity of bleed. In infants and toddlers mucosal bleed (gastritis and stress ulcers) is a common cause. In children above 2 y variceal bleeding due to Extra-Hepatic Portal Venous Obstruction (EHPVO) is the commonest cause of significant UGIB in developing countries as against peptic ulcer in the developed countries. Upper gastrointestinal endoscopy is the most accurate and useful diagnostic tool to evaluate UGIB in children. Parenteral vitamin K (infants, 1-2 mg/dose; children, 5-10 mg) and parenteral Proton Pump Inhibitors (PPI's), should be administered empirically in case of a major UGIB. Octreotide infusion is useful in control of significant UGIB due to variceal hemorrhage. A temporarily placed, Sengstaken-Blakemore tube can be life saving if pharmacologic/ endoscopic methods fail to control variceal bleeding. Therapy in patients having mucosal bleed is directed at neutralization and/or prevention of gastric acid release; High dose Proton Pump Inhibitors (PPIs, Pantoprazole) are more efficacious than H2 receptor antagonists for this purpose.
