Uncut Roux-en-Y reconstruction after distal gastrectomy for gastric cancer.

BACKGROUND: Choosing an optimal reconstruction method is pivotal for patients with gastric cancer undergoing distal gastrectomy. The uncut Roux-en-Y reconstruction, a variant of the conventional Roux-en-Y approach (or variant of the Billroth II reconstruction), employs uncut devices to occlude the afferent loop of the jejunum. This modification is designed to mitigate postgastrectomy syndrome and enhance long-term functional outcomes. However, the comparative benefits and potential harms of this approach compared to other reconstruction techniques remain a topic of debate. OBJECTIVES: To assess the benefits and harms of uncut Roux-en-Y reconstruction after distal gastrectomy in patients with gastric cancer. SEARCH METHODS: We searched CENTRAL, PubMed, Embase, WanFang Data, China National Knowledge Infrastructure, and clinical trial registries for published and unpublished trials up to November 2023. We also manually reviewed references from relevant systematic reviews identified by our search. We did not impose any language restrictions. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs comparing uncut Roux-en-Y reconstruction versus other reconstructions after distal gastrectomy for gastric cancer. The comparison groups encompassed other reconstructions such as Billroth I, Billroth II (with or without Braun anastomosis), and Roux-en-Y reconstruction. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures. The critical outcomes included health-related quality of life at least six months after surgery, major postoperative complications within 30 days after surgery according to the Clavien-Dindo Classification (grades III to V), anastomotic leakage within 30 days, changes in body weight (kg) at least six months after surgery, and incidence of bile reflux, remnant gastritis, and oesophagitis at least six months after surgery. We used the GRADE approach to evaluate the certainty of the evidence. MAIN RESULTS: We identified eight trials, including 1167 participants, which contributed data to our meta-analyses. These trials were exclusively conducted in East Asian countries, predominantly in China. The studies varied in the types of uncut devices used, ranging from 2- to 6-row linear staplers to suture lines. The follow-up periods for long-term outcomes spanned from 3 months to 42 months, with most studies focusing on a 6- to 12-month range. We rated the certainty of evidence from low to very low. Uncut Roux-en-Y reconstruction versus Billroth II reconstruction In the realm of surgical complications, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Billroth II reconstruction may make little to no difference to major postoperative complications (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.24 to 4.05; I² = 0%; risk difference (RD) 0.00, 95% CI -0.04 to 0.04; I² = 0%; 2 studies, 282 participants; very low-certainty evidence) and incidence of anastomotic leakage (RR 0.64, 95% CI 0.29 to 1.44; I² not applicable; RD -0.00, 95% CI -0.03 to 0.02; I² = 32%; 3 studies, 615 participants; very low-certainty evidence). We are very uncertain about these results. Focusing on long-term outcomes, low- to very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Billroth II reconstruction may make little to no difference to changes in body weight (mean difference (MD) 0.04 kg, 95% CI -0.84 to 0.92 kg; I² = 0%; 2 studies, 233 participants; low-certainty evidence), may reduce the incidence of bile reflux into the remnant stomach (RR 0.67, 95% CI 0.55 to 0.83; RD -0.29, 95% CI -0.43 to -0.16; number needed to treat for an additional beneficial outcome (NNTB) 4, 95% CI 3 to 7; 1 study, 141 participants; low-certainty evidence), and may have little or no effect on the incidence of remnant gastritis (RR 0.27, 95% CI 0.01 to 5.06; I2 = 78%; RD -0.15, 95% CI -0.23 to -0.07; I2 = 0%; NNTB 7, 95% CI 5 to 15; 2 studies, 265 participants; very low-certainty evidence). No studies reported on quality of life or the incidence of oesophagitis. Uncut Roux-en-Y reconstruction versus Roux-en-Y reconstruction In the realm of surgical complications, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Roux-en-Y reconstruction may make little to no difference to major postoperative complications (RR 4.74, 95% CI 0.23 to 97.08; I² not applicable; RD 0.01, 95% CI -0.02 to 0.04; I² = 0%; 2 studies, 256 participants; very low-certainty evidence) and incidence of anastomotic leakage (RR 0.34, 95% CI 0.05 to 2.08; I² = 0%; RD -0.02, 95% CI -0.06 to 0.02; I² = 0%; 2 studies, 213 participants; very low-certainty evidence). We are very uncertain about these results. Focusing on long-term outcomes, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Roux-en-Y reconstruction may increase the incidence of bile reflux into the remnant stomach (RR 10.74, 95% CI 3.52 to 32.76; RD 0.57, 95% CI 0.43 to 0.71; NNT for an additional harmful outcome (NNTH) 2, 95% CI 2 to 3; 1 study, 108 participants; very low-certainty evidence) and may make little to no difference to the incidence of remnant gastritis (RR 1.18, 95% CI 0.69 to 2.01; I² = 60%; RD 0.03, 95% CI -0.03 to 0.08; I² = 0%; 3 studies, 361 participants; very low-certainty evidence) and incidence of oesophagitis (RR 0.82, 95% CI 0.53 to 1.26; I² = 0%; RD -0.02, 95% CI -0.07 to 0.03; I² = 0%; 3 studies, 361 participants; very low-certainty evidence). We are very uncertain about these results. Data were insufficient to assess the impact on quality of life and changes in body weight. AUTHORS' CONCLUSIONS: Given the predominance of low- to very low-certainty evidence, this Cochrane review faces challenges in providing definitive clinical guidance. We found the majority of critical outcomes may be comparable between the uncut Roux-en-Y reconstruction and other methods, but we are very uncertain about most of these results. Nevertheless, it indicates that uncut Roux-en-Y reconstruction may reduce the incidence of bile reflux compared to Billroth-II reconstruction, albeit with low certainty. In contrast, compared to Roux-en-Y reconstruction, uncut Roux-en-Y may increase bile reflux incidence, based on very low-certainty evidence. To strengthen the evidence base, further rigorous and long-term trials are needed. Additionally, these studies should explore variations in surgical procedures, particularly regarding uncut devices and methods to prevent recanalisation. Future research may potentially alter the conclusions of this review.

[Epstein-Barr virus-associated gastritis with perigastric lymphadenopathy accompanied by infectious mononucleosis:a case report].

A 28-year-old female patient with no particular medical history had a sore throat seven days before admission. Subsequently, she developed malaise, right abdominal pain, and a fever of 38°C and visited our hospital. A blood test revealed a mild inflammatory response and elevated liver enzymes, and she was admitted to the hospital for detailed examination and acute liver injury treatment. Various viral tests and autoantibody measurements revealed elevated Epstein-Barr virus (EBV) immunoglobulin M and negative EB nuclear antigen antibodies. Therefore, she was diagnosed with primary infectious mononucleosis-associated EB viral hepatitis. Abdominal computed tomography upon admission revealed swollen lymph nodes around the stomach;thus, esophagogastroduodenoscopy (EGD) was performed. A histopathological examination revealed severe lymphocytic infiltration, and EB encoding region in situ hybridization demonstrated that 10-20% of the lymphocytes were EBV-infected. Drip and rest treatment improved the patient's liver enzymes, and her symptoms resolved. Repeat EGD after two months revealed improved gastric erosions. Here, we report a case of EBV-associated gastritis that was discovered due to perigastric lymphadenopathy accompanied by infectious mononucleosis. This report includes a review of the literature because a few studies reported EBV-associated gastritis.

Gastritis Cystica Profunda: A Rare Disease, a Challenging Diagnosis, and an Uncertain Malignant Potential: A Case Report and Review of the Literature.

Gastritis cystica profunda (GCP) has been defined as a rare submucosal benign gastric lesion with cystic gland growth. Due to its unclear etiopathogenesis, this lesion is often misdiagnosed and mistaken for other gastric masses. Currently, a standardized treatment for GCP lesions is still missing. Here, we illustrate a case of a patient admitted to our general surgery department for melena and general discomfort. No history of peptic ulcer or gastric surgery was present. Upper GI endoscopy was performed, showing a distal gastric lesion with a small ulceration on the top. CT-scan and endoscopic ultrasound confirmed the presence of the lesion, compatible with a gastric stromal tumor, without showing any eventual metastasis. Surgical gastric resection was performed. Histological findings were diagnostic for GCP, with cistically ectasic submucosal glands, chronic inflammation, eosinophilic infiltration and foveal hyperplasia. GCP is a very exceptional cause of upper-GI bleeding with specific histological features. Its diagnosis as well as its therapy are challenging, resulting in several pitfalls. Even though it is a rare entity, GCP should always be considered in the differential diagnosis of gastric submucosal lesions.

Helicobacter pylori Found Incidentally During Upper Endoscopy Performed for Diagnosis of Common Pediatric Gastrointestinal Diseases.

BACKGROUND: Helicobacter pylori ( H. pylori ) gastritis may be an incidental finding during upper endoscopy performed to diagnose celiac disease (CeD), inflammatory bowel disease (IBD) and eosinophilic esophagitis (EoE). We aimed to describe the incidence of H. pylori in children undergoing endoscopy for CeD, IBD and EoE and determine the indications for treatment. METHODS: A retrospective, single-center study based on the review of endoscopy reports of pediatric patients, diagnosed with CeD, IBD and EoE, between January 2017 and December 2021. Data collected included; age, gender, hematologic parameters, endoscopic, histologic and H. pylori culture results, and information on eradication treatment. RESULTS: H. pylori gastritis was diagnosed in 120 of 558 (21.5%) children [72 (60%) female, mean age 10.6 years] during gastroscopy performed for the diagnosis of other GI diseases. H. pylori was present in 87 of 404 (21.5%) CeD, 27 of 113 (23.9%) IBD and 6 of 41 (14.6%) EOE patients ( P = 0.46). The main indication for treatment was the presence of ulcers, in 4 of 120 (3.3%), and erosions in 17 of 120 (14.2%). Eradication treatment was recommended in 22 of 120 (18.3%) patients, 8 of 87 (9.2%) CeD, 10 of 27 (37%) IBD and 4 of 6 (66.7%) EoE patients, P < 0.001. Four independent positive treatment predictors were identified; age above 10 years {odds ratio (OR) = 10.57 [95% confidence interval (CI) 1.88-59.36], P = 0.007} the presence of nodular gastritis (OR = 5.03 [95% CI 1.09-23.15], P = 0.38), erosions [OR = 49.21 (95% CI 8.19-295.83), P < 0.000] and ulcers [OR = 22.69 (95% CI 1.25-410.22), P = 0.035]. CeD was a strong negative predictor for treatment [OR = 0.23 (95% CI 0.002-0.241), P = 0.002]. CONCLUSIONS: H. pylori gastritis is a common incidental finding during endoscopy. The indications for treatment are not well defined and should be further investigated.

Measurement of gastric wall thickness after laparoscopic sleeve gastrectomy: obesity comorbidities and gastric wall in Chinese patients with obesity.

Leakage of the sleeve remains constant after laparoscopic sleeve gastrectomy (LSG). This complication may be due to a mismatch between the staple height and gastric wall thickness (GWT). Our aim was to measure the GWT in Chinese patients with obesity and investigate the relationship between GWT and gender, body mass index (BMI), body weight, and obesity-related comorbidities. The GWT of 210 resected specimens after LSG was measured using a tissue measuring device, at a compression pressure of 8 g/mm2 at three predetermined locations: antrum, midbody, and fundus. Two hundred ten patients (171 female/39 male). The gastric wall was thickest at the antrum followed by the midbody and thinnest at the fundus (3.02 mm, 2.22 mm, and 1.6 mm, respectively). Patients with gastritis and those with reflux esophagitis had thicker GWT at the antrum; male had thicker GWT at the antrum and fundus; patients with body weight > 100 kg, and those with BMI > 40 kg/m2 had thicker GWT at the fundus. Linear regression analysis revealed a significant association between GWT with body weight and BMI at the antrum and fundus; Furthermore, hypertension associated with the GWT at the fundus (P < 0.01, P < 0.01, P < 0.02, P < 0.01; and P < 0.04, respectively). This study showed that the anatomical location of the gastric wall is a major predicting factor of GWT. Furthermore, gastritis, reflux esophagitis, male gender, BMI > 40 kg/m2, body weight > 100 kg, and hypertension may increase the GWT at the antrum and fundus in Chinese patients with obesity.

Critical influence of cytokines and immune cells in autoimmune gastritis.

Gastric cancer (GC) is a type of the most common cancers. Autoimmune gastritis (AIG) and infection with Helicobacter pylori (HP) are the risk factors of triggering GC. With the emphasis on the treatment of HP, the incidence and prevalence of HP infection in population is decreasing. However, AIG lacks accurate diagnosis and treatment methods, which occupies high cancer risk factors. AIG is controlled by the immune environment of the stomach, including immune cells, inflammatory cells, and infiltrating intercellular material. Various immune cells or cytokines play a central role in the process of regulating gastric parietal cells. Abnormal expression levels of cytokines involved in immunity are bound to face the risk of tumorigenesis. Therefore, it is particularly important for preventing or treating AIG and avoiding the risk of gastric cancer to clarify the confirmed action mode of immune cells and cytokines in the gastric system. Herein, we briefly reviewed the role of the immune environment under AIG, focussing on describing these double-edged effects between immune cells and cytokines, and pointing out potential research challenges.

Endoscopic and histopathological assessment of individuals undergoing one anastomosis gastric bypass: a 2-year follow-up.

BACKGROUND: There is much debate over the occurrence of biliary reflux to the gastric pouch after one anastomosis gastric bypass (OAGB) and its potential risks. OBJECTIVE: To assess endoscopic and histopathological findings following a standardized protocol of biopsy collection two years after OAGB. METHODS: A historical cohort study was conducted, based on a prospectively collected database, which involved 39 participants who underwent OAGB. Participants underwent clinical evaluation and esophagogastroduodenoscopy at the time of surgery and 24 months afterward. Post-operatively, biopsy specimens in esophagogastric junction, pouch, and anastomosis were systematically collected. RESULTS: 92.3% of the participants were female and the mean age was 37 ± 8.5 years. The mean body mass index (BMI) significantly decreased from 37.6 ± 5.7 kg/m2 to 27 ± 4.1 kg/m2 after 2 years (p < 0.001). The mean %TWL was 27.2 ± 10.5%. The prevalence of non-erosive gastritis significantly increased from 25.6 to 51.3% (p = 0.02). Erosive gastritis significantly decreased from 28.2 to 10.3% (p = 0.04). Four cases of marginal ulcers were identified (10.3%). The commonest histopathological finding was mild inflammation in 74.3% (esophagogastric junction), 58.9% (pouch), and 71.8% (anastomosis). There was one case of focal intestinal metaplasia in each site of interest and no cases of dysplasia or severe inflammation. CONCLUSIONS: Using a standardized protocol of post-operative biopsy collection, low rates of severe endoscopic and histopathological abnormalities were observed two years after OAGB. Nevertheless, as most patients have histologically proven inflammation, bile in the gastric pouch, and endoscopic gastritis, long-term surveillance is essential because of the uncertain risk of these abnormalities.

Clinical course and treatment of radiation-induced hemorrhagic gastritis: a case series study.

Radiation-induced hemorrhagic gastritis is a relatively uncommon complication of irradiation that can be severe. However, appropriate treatment guidelines have not yet been established because of the small number of known cases. At our hospital, we encountered nine cases of radiation-induced hemorrhagic gastritis between July 2005 and July 2018. All patients initially underwent argon plasma coagulation (APC) for hemostasis. The treatment was highly effective, and hemostasis was successfully achieved in eight of the cases. Hemostasis could not be achieved in one case treated with APC; therefore, surgical resection was required. This patient had risk factors, such as liver cirrhosis and a history of abdominal surgery. Our case series suggests that APC is an effective hemostatic method that should be considered as the initial treatment option for radiation-induced hemorrhagic gastritis; however, surgical resection may be considered when the patient is at high risk for rebleeding.

Prevalence and Clinical Impact of Abnormal Findings in Routine Upper Digestive Endoscopy Before Bariatric Surgery.

Background: The role of preoperative upper digestive endoscopy has been discussed with controversy in bariatric surgery. This study aims to evaluate the prevalence of endoscopic findings in obese patients undergoing bariatric surgery and their clinical impact. Methods: A retrospective observational study of all patients who performed upper endoscopy before bariatric surgery between January 2019 and December 2021 was performed. A total of 612 patients were identified, mostly females (79.2%), with a mean age of 43.9 years. Abnormal endoscopic findings were identified in 474 (77.5%) patients, including erythematous gastropathy (59.2%), reflux esophagitis (13.6%), erosive gastritis (10.6%), and hiatal hernia (8.0%). Importantly, Barrettâ??s esophagus was also identified in four patients and gastric adenocarcinoma in one. All performed gastric biopsies that revealed H. pylori gastritis in 368 (60.1%). Taken together, abnormal endoscopic and histological findings influenced perioperative management of 403 (65.8%) patients, including preoperative medical therapy in 378 (61.8%), endoscopic treatment of mucosal lesions in 47 (7.7%), direct influence in surgical strategy in 27 (7.8%) and contraindication to bariatric surgery in 1 (0.2%). Conclusion: Preoperative upper endoscopy identifies a wide range of abnormal findings in obese patients, which often influence peri-operative management. Therefore, it must be considered in all patients prior to bariatric surgery.

Gastric emphysema after percutaneous endoscopic gastrostomy placement.

Emphysematous gastritis and gastric emphysema are different diseases. Sometimes, we treat the diseases without distinguishing them clearly because both are rare, and the mortality rate of emphysematous gastritis cases is high (55%). Gastric emphysema is more well known than is emphysematous gastritis after percutaneous endoscopic gastrostomy (PEG) placement (80%). Particularly, it is a self-healing disease, and treatment with antibiotics is not required. CT is commonly used to diagnose emphysematous gastritis and gastric emphysema. The amount of radiation exposure is a concern for performing multiple CTs following air disappearance in the gastric wall. Here, we report the case of a 92-year-old man with gastric emphysema after PEG. It was useful to follow-up the patient by performing radiographic examination, and the disease was managed conservatively without antibiotic administration. We report that distinguishing gastric emphysema from emphysematous gastritis was necessary. Moreover, performance excessive tests and treatments should be avoided.

Do obesity and diabetes increase the frequency and risk of bile reflux gastritis post-cholecystectomy?

<br><b>Introduction:</b> Biliary gastropathy is a disease characterized by upper abdominal pain, frequent heartburn, nausea, and vomiting of bile. It is caused by the backward flow of duodenal fluid into the stomach and esophagus.</br> <br><b>Aim:</b> A retrospective cohort study was performed to estimate the prevalence and risk factors of bile reflux gastritis secondary to cholecystectomy and to evaluate the endoscopic and histopathologic changes in gastric mucosa caused by bile reflux gastritis.</br> <br><b>Materials and methods:</b> The study involved 64 patients with epigastric pain and/or dyspeptic symptoms during the period from January 2018 to December 2020 who presented to Zagazig University Hospitals. The subjects were divided into two groups: the control group (CG), with 30 subjects who had never undergone any biliary interventions, and the post-cholecystectomy group (PCG), consisting of 34 patients who had undergone cholecystectomy.</br> <br><b>Results:</b> The prevalence of bile reflux gastritis was 16.7% in the CG and 61.8% in the PCG. In both groups, diabetes, obesity, increased gastric bilirubin, and increased gastric pH were risk factors for bile reflux gastritis (r = 0.28, 0.48, 0.78, and 0.57, respectively). However, there were no correlations between age, sex, epigastric pain, heartburn, vomiting, and the presence of bile reflux gastritis.</br> <br><b>Discussion:</b> Bile reflux gastritis is a common complication following cholecystectomy and is more common among obese and diabetic patients.</br>.

Oesophageal pneumatosis: computed tomographic characteristics in three dogs (2018-2021).

BACKGROUND: Oesophageal pneumatosis (OP) is defined as the presence of gas within the oesophageal wall. The description of this condition in veterinary medicine is currently lacking. The pathogenesis of alimentary tract pneumatosis remains unclear. Current literature describes that access of gas into the oesophageal wall may occur by one or a combination of the following mechanisms: mucosal disruption, increased intra or extra-luminal pressure or dissection of gas from an extra-oesophageal source. OBJECTIVES: The aim of this multi-centric case series was to describe the computed tomography (CT) findings of OP in dogs. METHODS: Three adult dogs were included. One dog presented with gastrointestinal signs and general malaise while the other two presented with spontaneous facial and cervical subcutaneous emphysema. RESULTS: CT revealed different degrees of intramural gas along the oesophageal wall in all cases. The first dog was diagnosed with emphysematous gastritis based on the presence of gastric pneumatosis paired with compatible clinicopathological and endoscopic findings. This dog was successfully treated with antibiotics. The remaining two dogs were diagnosed with spontaneous pneumomediastinum and required no surgical or medical treatment. CONCLUSIONS: In all cases with OP, there was concurrent gastric pneumatosis. Gas extensively and circumferentially distributed with a banded shape along the oesophageal wall was present in patients with presumed mural gas dissection because of pneumomediastinum. Conversely, a focal and mild amount of mural gas with a tubular shape was identified in the distal segment of the oesophagus in the patient with emphysematous gastritis.

6'-O-Galloylpaeoniflorin attenuates Helicobacter pylori-associated gastritis via modulating Nrf2 pathway.

As a common disease of the digestive system, chronic gastritis is inflammation of the gastric mucosa caused by various factors. Helicobacter pylori (H. pylori) is one of the main causes of chronic gastritis, which can lead to gastric mucosal damage and gland atrophy, thereby promoting gastrocarcinogenesis. Oxidative stress and the inflammatory response are important mechanisms of H. pylori-induced gastritis. 6'-O-Galloylpaeoniflorin (GPF) is a substance isolated from peony root with antioxidant and anti-inflammatory activities. However, its role and mechanism in the pathogenesis of H. pylori-induced chronic gastritis remain unclear. This study explored the effects of GPF on H. pylori-induced gastric mucosal oxidative stress and inflammation using flow cytometry, western blotting, real-time quantitative PCR, and immunohistochemistry. We found that H. pylori infection increased oxidative stress and expression of inflammatory cytokines in vitro and in vivo and that these outcomes were inhibited by GPF. Furthermore, GPF activated nuclear factor erythroid-related factor-2 (Nrf2) and its downstream target genes in H. pylori-infected GES-1 cells and mice. The anti-inflammatory and antioxidant effects of GPF on H. pylori-infected cells were attenuated by an Nrf2 inhibitor. Taken together, these data suggest that GPF reduces H. pylori-induced gastric mucosa injury by activating Nrf2 signaling and that GPF is a potential candidate for the treatment of H. pylori-associated gastritis.

Clinical Characteristics and Outcomes of Gastritis Associated With Immune Checkpoint Inhibitors: Scoping Review.

Among immune-related adverse events associated with immune checkpoint inhibitors, immune-mediated gastritis (IMG) has been rarely described in the literature and has not yet been well characterized. This scoping review aimed to characterize IMG in terms of precipitating agents, clinical presentations, and prognosis. After the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews, we searched MEDLINE and EMBASE for all peer-reviewed articles using keywords including "gastritis," "immune checkpoint inhibitor," and "immune-related adverse event" from their inception to December 28, 2021. Twenty-two articles, including 5 observational studies and 17 case reports and case series, were included. Nivolumab, pembrolizumab, and combination therapy with those and cytotoxic T-lymphocyte-associated antigen-4 inhibitor (ipilimumab) were commonly used in those with IMG. 59.8% had epigastric pain, and 50% had erosive gastritis. 87.5% had Common Terminology Criteria for Adverse Events (CTCAE) grade 3 gastritis, and 91.2% received corticosteroids. Recurrence was noted in 16.7%, and only 1 expiration was noted. 4.3% had positive helicobacter pylori and cytomegalovirus from the gastric specimen. Similar to immune-related colitis, patients with IMG may have a favorable prognosis with a better response to immune checkpoint inhibitors if treated appropriately. The diagnosis of IMG is made by exclusion, and a thorough workup is necessary to rule out concurrent helicobacter pylori and cytomegalovirus involvement. Further studies are critical for a better understanding of this complication.

Comparison of gastrointestinal symptoms and findings in renal replacement therapy modalities.

OBJECTIVE: Chronic kidney disease (CKD) affects gastrointestinal system (GIS) and causes histological, functional and mucosal changes. There are scarce data investigating GIS symptoms and findings in patients with CKD stage III-V, receiving hemodialysis (HD) and peritoneal dialysis (PD). In this study, we aimed to evaluate the frequency of gastrointestinal symptoms and findings and compare between renal replacement therapies. METHOD: A total of 290 patients (97 in CKD stage III-V, 92 PD, 101 HD) were included in this study. Gastrointestinal complaints, diseases, background characteristics of patients and drugs they used were questioned by interviews, forms were filled and examinations of patients were performed. Results of upper GIS endoscopy, colonoscopy, abdominal ultrasonography and tomography of patients were evaluated. RESULTS: The most common signs were dyspepsia (50%), nausea (45%) and epigastric pain (44%) among all patients, generally. Gastrointestinal disorders like gastritis (62%) and gastroesophageal reflux (39%) were frequent in patients. Prevalence of patients with weight loss was 20% in predialysis and 8% in PD and the ratio was higher in predialysis group statistically significantly (p = 0,016). The prevalence of gastritis was 70% in PD, 55% in HD and the prevalence of hemorrhoids was 24% in PD and 12% in HD. The prevalence of gastritis and hemorrhoids was higher in the PD group than in the HD group statistically significantly (p = 0.043, p = 0.028), otherwise, there wasn't a difference between the PD and predialysis groups, statistically significantly. CONCLUSION: This study showed that; gastrointestinal symptoms and disorders were very common in CKD, besides this; while gastritis and hemorrhoids were more frequent in the PD, esophagitis and hiatal hernia were more frequent in the HD.

Pattern-based approach to gastritis and gastropathy.

Histological investigation of non-neoplastic endoscopic biopsies of gastric mucosa is one of the most common tasks most pathologists have to face on daily basis. Although the most common clinical question is still being whether Helicobacter organisms are found, pathologists have to bear in mind the whole spectrum of causes and associated morphological patterns of gastritides and gastropathies, governed by characteristic combinations of various types of inflammatory infiltrate, alterative and reactive changes of epithelial component, vascular response, and variability of stromal composition. The association of histopathologic pattern with supposed etiology can be sometimes proved by direct detection of the cause of morphologic changes in the investigated endoscopic sample.

Optimal Reconstruction After Laparoscopic Distal Gastrectomy: A Single-Center Retrospective Study.

OBJECTIVES: Although laparoscopic distal gastrectomy has been widely used for distal gastric cancer, the best functional reconstruction type has not yet been established. Based on previous experience, we propose a modified uncut Roux-en-Y anastomosis. This study aimed to compare the outcomes of different intracorporeal anastomoses after laparoscopic distal gastrectomy. METHODS: From April 2015 to August 2020, the data of 215 patients who underwent laparoscopic distal gastrectomy was collected. The patients were divided into 4 groups according to the digestive tract reconstruction method, Billroth-I, Billroth-II, Roux-en-Y, and the modified uncut Roux-en-Y. Clinicopathologic characteristics, surgery details, short-term outcomes, and postoperative nutritional status were analyzed. RESULTS: The operation time of Billroth-I anastomosis was significantly shorter (216.2 ± 25.8 min, P < .001) than that of other methods. There was no difference in postoperative complications and OS among the 4 reconstruction methods. The incidences of esophagitis, gastritis, and bile reflux were significantly lower in the Roux-en-Y and uncut Roux-en-Y group (P < .001) 1 year after surgery. And the postoperative albumin and PNI levels in uncut Roux-en-Y group were higher than those in other groups(P < .05). On multivariate analysis, age and reconstruction type were independently related to esophagitis, gastritis, and bile reflux. Serum albumin and the prognostic nutritional index were significantly higher in the uncut Roux-en-Y group than other groups (P < .05). CONCLUSIONS: All 4 reconstruction techniques are feasible and safe. The Roux-en-Y and uncut Roux-en-Y are superior to Billroth-Ⅰ and Billroth-Ⅱ+Braun in terms of reflux esophagitis, gastritis, and bile reflux. Uncut Roux-en-Y may result in better PNI than the others.

Clinical Presentation of Cases with Upper Gastro - Intestinal Bleeding.

Acute upper gastrointestinal bleeding (UGIB) is a common emergency and can be a serious condition that requires hospitalization, rapid evaluation and management. The usual presentation is hematemesis (vomiting of blood or coffee ground-like material) and/or melena (black, tarry stools) 1. UGIB occurs more commonly in men and older subjects. PUD is the most common cause of UGIB in the US accounting for about 50% of the cases, whereas in tropical country like India, esophageal varices attribute to half the cases. Esophago-Gastro-Duodenoscopy [EGD] is a primary diagnostic and therapeutic modality in the setting of UGIB. MATERIAL: Prospective study. Forty patients who have presented with frank blood or coffee ground color vomitus and/or melena were considered for this study. All patients greater than 18 years of age were included. Their clinical presentation, hemogram and endoscopic findings were analyzed. Descriptive statistical analysis has been applied. OBSERVATION: In our study, the age distribution was between 23 and 87 years. There is a male preponderance with 65 % males and 35%females. Among 40 patients,42.5%had varices, 17.5% had Peptic Ulcer Disease and12.5% had Erosive Gastritis. The other causes of UGIB include Pangastritis(10%), Mallory Weiss Tear(7.5%), Polyp(5%), Esophagitis(2.5%), Coagulopathy induced bleed(2.5%) and Carcinoma stomach(2.5%). Of the 40 cases admitted, only 3 patients (7.5%) had massive Upper GI Bleed.10 patients (25%) had moderate bleed and 27 patients (67.5%) had mild bleed. Amongst the patients with massive bleed, an important cause is esophageal varices(66.7%). A total of 21 (52.5%) patients have recovered. There was one death(2.5%) amongst the cases which was not attributed to UGIB. 14 patients(45%) has residual disease of which 42.5% were of variceal bleed. Patients with variceal bleed have undergone banding and have been asked to regularly follow up for check endoscopy and banding till their eradication. There was 1 patient of residual disease with Carcinoma stomach(2.5%) who has been initiated on chemotherapy. CONCLUSION: Hematemesis is much commoner than melena in the presentation of upper GI bleed. EGD has a diagnostic as well as therapeutic role in UGIB .In this study endoscopy provided diagnosis in 97.5% of patients. In this cross sectional study, the most common cause of upper GI bleed was esophageal varices, with alcoholic cirrhosis being the main cause of portal hypertension. Varices remain to be the most common cause of UGIB in both males and females, however, the percentage is more in males as compared to females. Varices are an important cause of massive variceal bleed.

Unusual Presentation of Helicobacter pylori Infection as PSMA-Avid Gastric Mass.

ABSTRACT: 68 Ga-PSMA PET/CT is one of the most common imaging uses for prostate cancer imaging. Although initially thought to be specific for prostate cancer, there are many evidences that are coming of its concentration in many other neoplastic and nonneoplastic pathologies. Helicobacter pylori is the most common bacteria causing gastric inflammation and usually presents with gastroduodenal ulcer. Here we present one unusual case of benign gastric mass formation caused by H. pylori infection with PSMA concentration.
