An 80-year-old woman presented with a 30-mm protruding lesion-like submucosal tumor with a central depression located at the anterior wall of the upper gastric body. The depressed area had a well-demarcated margin, while the other area was covered by a non-neoplastic mucosa. A biopsy specimen revealed neuroendocrine carcinoma. Endoscopic ultrasonography revealed a heterogeneous mass with a clearly distinguished border in the submucosal layer. The mass had two distinct areas adjacent to each other. In addition, a hypoechoic zone was observed on the margin of the mass. Distal gastrectomy was performed. The final diagnosis was a mixed neuroendocrine-non-neuroendocrine neoplasm arising from the heterotopic gastric gland.

Protein-losing gastroenteropathy is a rare syndrome of protein loss from the gastrointestinal system. It manifests with hypoproteinemic edema, which may be due to either lymphatic leakage due to increased interstitial pressure or leakage of protein-rich fluids due to intestinal disorders. Our case describes a 65-year-old female with life-threatening protein-losing enteropathy (PLE) requiring multiple transfers to intensive care unit for vasopressor support. In this rare instance, her extensive initial workup did not reveal any etiology for PLE, but she was later found to have underlying Crohn’s colitis. Protein-losing enteropathy is an underdiagnosed complication of inflammatory bowel disease and must be considered while treating patients with colitis.

BACKGROUND Predominance of blind feeding tube placement makes esophageal tube misplacement and aspiration risk commonplace. Accurate estimation of nose-to-stomach length could reduce this risk. Standards for estimating this length were audited against the length measured from guided tube placement. METHODS This prospective, single-center observational study used electromagnet-guided tube placement to measure the length from nose to gastric body flexure as part of routine care. This measurement was used to audit standard equations used to estimate this length from external measures: xiphisternum-ear-nose + 10 cm (XEN+10), nose-ear-xiphisternum (NEX), and Hanson_A and Hanson_B. RESULTS From April 23, 2015, to March 2, 2020, measurements were obtained from 200 primary tube placements. Median length to the gastric body flexure (61 cm) was significantly different from that to the pre-gastroesophageal junction flexure (48 cm) or lengths predicted by NEX (51 cm) or Hanson_A (50.5 cm) and Hanson_B (56.1 cm) (all P < .00001) but similar to XEN+10 (61 cm). Esophageal placement was a potential risk for all methods (NEX: 96.3%, Hanson_A: 99.5%, Hanson_B: 86.9%, XEN+10: 43.2%) and a definite risk for most (NEX and Hanson_A: 14.9%, Hanson_B: 1%, XEN+10: 0%). CONCLUSIONS NEX and Hanson methods of predicting the length from nose to gastric body flexure are too short and risk esophageal misplacement. XEN+10 reduces but does not eliminate this risk. External measurement predictions are clinically unsafe as a guide blind tube placement. Guided placement is recommended.

A foreign body can be intentionally or accidentally ingested. Timing of endoscopy relies on foreign body shape and size, location in gastrointestinal tract, patient's clinical conditions, occurrence of symptoms or onset of complications. In this short case, we present a middle age woman, who accidentally swallowed a portion of a nasopharyngeal swab half-broken during a diagnostic test for SARS-CoV-2. Upper gastrointestinal endoscopy was promptly performed to prevent the swab from crossing the pylorus leading to serious complications and, therefore, risk of surgical intervention. The broken nasopharyngeal swab was detected in the gastric body, and immediately removed with a foreign body forceps. Our hospital performs many nasopharyngeal swabs and to our knowledge, this is only the second reported swab ingestion during SARS-CoV-2 test. This article is protected by copyright.

A 61-year-old male was hospitalized in our department due to Intermittent melena for 4 days. Laboratory tests showed a reduced hemoglobin level (10.7 g/L). Abdominal computed tomography (CT) showed gastric wall thickening in the gastric body.

Background: Functional dyspepsia (FD) is associated with poor health-related quality of life. Recent evidence suggests that the main pathogenesis suspect is the gut mucosa-associated microbiota (MAM). However, little is known about the MAM in FD subjects. The aim of this study was to clarify the relationship between upper gastrointestinal symptoms in FD and the characteristics of the gastrointestinal MAM. Summary: Five mucosa samples from the upper gut (intraoral, mid-esophagus, gastric body, gastric antrum, and descending portion of the duodenum) were collected with a brush under endoscopic examination from FD and healthy control subjects. MAM profiles of each sample were analyzed by 16S-rRNA ­V3-V4 gene sequences. Questionnaire was used to assess gastrointestinal symptoms in FD. Between FD and healthy control subjects, although the comparison of MAM α-diversity showed no significant differences, the structure of MAM (β-diversity) was clearly different. Only the phylum Firmicutes was increased in FD compared to healthy control subjects in all sites of the upper gut. At the genus level, Streptococcus was significantly increased in all sites in the upper gut in FD. The relative abundance of Streptococcus was positively correlated with upper gastrointestinal symptoms in each upper gut group. Furthermore, the relative abundance of OTU 90 was positively correlated with upper gastrointestinal symptoms in all sites in the upper gut in FD. Key Messages: Streptococcus is a bacterium strongly correlated with upper gastrointestinal symptoms in FD.

The upper gastric body is of particular interest in relation to gastrectomy because this area includes a border; that is, both distal and proximal gastrectomy for early gastric cancer can involve this area. Laparoscopic subtotal gastrectomy (LsTG) is reported to be suitable procedure compared with laparoscopic proximal and total gastrectomy (LPG, LTG), regarding postoperative nutritional status and surgical safety. However, whether LsTG is an oncologically acceptable procedure for early gastric cancer in the upper gastric body is unclear. We analyzed 215 patients with cT1N0M0 gastric cancer limitedly located in the upper gastric body. The frequency of conversion from each intended procedure to an alternative procedure, the width of the pathological margin, the incidence of lymph node metastasis at each station and the 3-year overall survival (OS) and relapse-free survival (RFS) were evaluated. LsTG was planned for 65 patients, and LPG for 72 and LTG for 78, respectively. Conversion to other procedures was required in about 10% of patients for whom LsTG or LPG was planned. The width of the pathological margin in patients who underwent LsTG was significantly shorter than patients who underwent the others. No patients who underwent LsTG, LPG or LTG had metastases in station no. 2 or 4sa lymph node. The 3-year OS and RFS rates of patients for whom each procedure was planned were not different. LsTG could be an oncologically acceptable procedure for cT1N0M0 gastric cancer in the upper gastric body. LsTG could be one option for such disease.

Gastric mucosa has been widely studied during the pre/post-Helicobacter pylori (Hp) era. Excluding peptic ulcer disease (PUD), the duodenal mucosa has not been thoroughly analyzed, even less so in functional dyspepsia (FD). We would like to make some comments after studying 161 dyspeptic patients with samples taken from the gastric body, antrum, proximal and distal duodenum.

A 74-year-old male patient was admitted to our hospital, who complained of abdominal distension for 1 year with no previous history of disease. Esophagogastroduodenoscopy (EGD) revealed a submucosal tumor (SMT) in the gastric body.

In the past decade, laparoscopic sleeve gastrectomy (LSG) has gained significant popularity as a treatment for obesity. However there has been significant morbidity and mortality associated with post-operative anastomotic leaks. The reported incidence of LSG leaks range between 0.1 and 7% and can be higher in re-operative surgery (Deitel et al., Surg Obes Relat Dis 7(6):749–759, 2011; Kim et al., Surg Obes Relat Dis 11(4):739–748, 2015; Moszkowicz et al., Obes Surg 23(5):676–686 2013). Within the literature, the causes of a staple line leak are broadly grouped into either ischemic or mechanical causes. Leaks commonly occur in the proximal third of the anastomosis: large majority (>80%) at the angle of His or at the gastroesophageal junction (GEJ) and to a lesser degree the mid-aspect of the gastric body or distal third (Moszkowicz et al., Obes Surg 23(5):676–686 2013; Baker et al., Obes Surg 14(10):1290–1298 2004; Garofalo et al., Surg Obes Relat Dis 13(6):925–932, 2017).

La fibromatosis tipo desmoide es un tumor benigno de suma rareza con caracteristicas localmente agresivas. Se desarrolla en especial en tejidos blandos por su origen en los musculos y las aponeurosis. El diagnostico se establece por inmunohistoquimica con positividad para vimentina, B-catenina y en ocasiones para actina de musculo liso. El espectro clinico de presentacion es amplio, y segun este y la resecabilidad se ofrece el tratamiento. Presentamos el caso de una paciente con sintomas de obstruccion al vaciamiento gastrico secundaria a una lesion subepitelial en cuerpo con inmunohistoquimica concluyente para fibromatosis gastrica. Desmoid-type fibromatosis is an extremely rare benign tumor with locally aggressive features. It is predominantly developing in soft tissues due to its origin in muscles and aponeurosis. The diagnosis is established by immunohistochemistry with positivity for vimentin, B-catenin and sometimes for smooth muscle actin. The clinical spectrum of presentation is wide, based on this and resectability the treatment is offered. We present the case of a patient with symptoms of gastric outlet obstruction secondary to a subepithelial lesion in the gastric body with conclusive immunohistochemistry for gastric fibromatosis.

BACKGROUND: Endoscopic submucosal dissection (ESD) is a complex endoscopic procedure, with high rates of adverse events and technical difficulties. To overcome that problem, many training centers published the importance of animal models for skill acquirement in ESD. However, no study has used the submucosal dissection depth (DSUB) as a parameter to evaluate the learning curve in ESD, which might be a relevant factor since an optimal resection plane is important to achieve a curative resection and avoid intraoperative complications. OBJECTIVE: This study aimed to assess ESD skill acquirement after short-term training sessions by evaluating the submucosal dissection depth (DSUB) and the association with adverse events. METHODS: This experimental study included 25 experienced endoscopists in therapeuthic procedures (>5years) and 75 specimens resected by ESD (three resections / endoscopist). Learning parameters (resection time, size, en bloc resection rate, bleeding, perforation and submucosal dissection depth) were prospectively evaluated. The percentages of DSUB of all specimens resected were calculated. RESULTS: All specimens were resected from the gastric body (n=75). The mean size of the resected specimens was 23.97±7.2 mm. The number of adverse events, including bleeding, perforation, and death, were 17 (22.67%), 3 (4%), and 0 cases, respectively. The average mean time by the third dissection decreased from 28.44±9.73 to 18.72±8.81 min (P61% of the submucosal layer, the risk for bleeding during the procedure decreased (PPV, 0.97; 95% CI, 0.85-0.99). CONCLUSION: Improvement in the learning curve in ESD and a better cognitive ability were seen by the third dissection in these short term training courses. And a significant association between DSUB and the risk of bleeding.

The results of treatment of 112 patients of elderly and senile age patients with non-metastatic gastric cancer, complicated by bleeding were analyzed. Most often bleedings occurred for stomach cancer stage III−IV. The tumor was commonly located in the gastric body. The vast majority of patients had only one complication — bleeding. In the second (control) group, there was no unified diagnostic and treatment algorithm, patients were usually operated urgently upon admission or in case of recurrent bleeding. The differential diagnostic and treatment algorithm was developed for patients of group I (main) taking into account the condition of a patient and the severity of bleeding or repeated bleeding. In the control group, the indications for emergency surgery were continued bleeding and inefficiency of endoscopic hemostasis. In the main group, the risk of recurrent bleeding was considered as well, and in case of high risk emergency surgery was performed after a full preoperative preparation. In addition, the cardial part or 2/3 of the stomach were not resected by reason of the deliberate non-radical tactics. It is worth noting that in the I group argon plasma coagulation, complemented by the hemostatic system EndoClot was used for endoscopic hemostasis. Through the use of the developed algorithm we managed to reliably reduce the frequency of complications from 50 to 28.5% (p

Electromagnetic (EM)-guided tube placement has been successfully used to pre-empt lung misplacement, but undetected misplacements continue to occur. The authors conducted an audit to investigate whether official Cortrak or local guidance enabled differentiation of gastrointestinal (GI) from lung traces. X-ray, pH or an EM trace beyond the gastric body were used to independently confirm gastric position. The authors undertook 596 nasointestinal (NI) tube placements, of which 361 were primary GI placements and 41 lung misplacements. Official guidance that in GI traces a midline deviation is absent cannot differentiate GI from lung traces because deviation is common in both. However, when comparing a trace in the same patient, midline deviation during lung misplacement always occurred >18 cm above the horizontal line compared with only 33% of the subsequent GI deviation (p

Resumen La lesión de Dieulafoy representa aproximadamente el 2% de todos los casos de hemorragia gastrointestinal superior. En la mayoría de casos esta anomalía se ubica en el estómago, principalmente en la curvatura menor. Se presenta el caso de un adulto joven con hematemesis y signos de hipovolemia. Durante la esofagogastroduodenoscopia se evidenció un coágulo adherido en el cuerpo gástrico a nivel de la curvatura mayor, sugestivo de lesión de Dieulafoy. Inicialmente se realizó manejo médico sin mejoría significativa, por lo que se realizó laparotomía exploratoria con resección de la malformación vascular, finalmente con el informe histopatológico se confirmó el diagnóstico. A pesar de ser una causa infrecuente de hemorragia gastrointestinal superior, la lesión de Dieulafoy debe considerarse entre los diagnósticos diferenciales, especialmente si la hemorragia persiste aún con manejo médico. MÉD.UIS.2019;32(i):27-31. Abstract Dieulafoy's lesion represents approximately 2% of all causes of upper gastrointestinal bleeding. In most cases, this malformation is located in the stomach, mainly in the lesser curvature. We present the case of a young adult with hematemesis and signs of hypovolaemia. During the esophagogastroduodenoscopy, a clot adhering to the gastric body was seen at the level of the greater curvature, suggestive of Dieulafoy's lesion. Initially, medical management was performed without significant improvement, so an exploratory laparotomy was performed with resection of the vascular malformation, the histopathological report confirmed the diagnosis. Despite being an uncommon cause of upper gastrointestinal bleeding, the Dieulafoy lesion must be considered among the differential diagnoses, especially if the hemorrhage persists even with medical management. MÉD.UIS.2019;32(1):27-31.

Absztrakt: Az extrém kövérség kezelésére kifejlesztett eljárások közül az állítható gyomorgyűrű korábban igen elterjedt volt. Alkalmazását azonban számos késői panasz, illetve szövődmény kísérte, ezért egyre gyakrabban fordul elő, hogy eltávolításra kerülnek. Egy ilyen beavatkozás után fél évvel kialakult teljes gyomorkimeneti elzáródás klinikai képét előidéző belső kizáródás esetét mutatjuk be. A belső kizáródást az okozta, hogy a pylorusrégió becsúszott a gyűrű eltávolításakor készített plicatio és a gyomorcorpus fala közé. A beteg a műtéti megoldás után gyógyult. Hasonló okból kialakult gyomorelzáródás esetével az irodalom tanulmányozása során nem találkoztunk.

Foreign body (FB) ingestion is a common occurrence in the United States with a reported incidence of 120 per 1 million people, accounting for up to 1500 fatalities annually. The majority of FB ingestions will pass through the gastrointestinal tract spontaneously, while in 10% to 20% of patients, intervention will be necessary. A variety of endoscopic devices can be utilized to facilitate FB removal from the gastrointestinal tract, including snares, retrieval nets, and grasping forceps. We report the case of a 58-year-old female who required utilization of endoscopic scissors for FB removal in the setting of multiple failed attempts with traditional methods. This case highlights a novel approach to gastric FB removal utilizing endoscopic scissor forceps, which should be considered in select cases to further improve the efficacy of endoscopic FB removal and reduce the need for surgical intervention.

Aim. To evaluate the efficacy and safety of endoscopic submucosal tunnel dissection (ESTD) for resection of large superficial gastric lesions (SGLs). Methods. The clinicopathological records of patients performed with ESTD or endoscopic submucosal dissection (ESD) for SGLs between January 2012 and January 2014 were retrospectively reviewed. 7 cases undergoing ESTD were enrolled to form the ESTD group. The cases were individually matched at a 1 : 1 ratio to other patients performed with ESD according to lesion location, ulcer or scar findings, resected specimen area, operation time and operators, and the matched cases constituting the ESD group. The treatment outcomes were compared between the two groups. Results. The mean specimen size was 46 mm. 10 lesions were located in the cardia and 4 lesions in the lesser curvature of the lower gastric body. En bloc resection was achieved for all lesions. The mean ESTD resection time was 69 minutes as against 87.7 minutes for the ESD (P=0.01). The mean resection speed was faster for ESTD than for ESD (18.86 mm2/min versus 13.76 mm2/min, P=0.03). There were no significant differences regarding the safety and curability during the endoscopic follow-up (mean 27 months). Conclusions. ESTD is effective and safe for the removal of SGLs and appears to be an optimal option for patients with large SGLs at suitable sites.

Background and study aims: Endoscopic submucosal dissection (ESD) using insulation-tipped knives (IT knives) to treat gastric lesions located on the greater curvature of the gastric body remains technically challenging because of the associated bleeding, control of which can be difficult and time consuming. To eliminate these difficulties, we developed a novel strategy which we have called the “near-side approach method” and assessed its utility. Patients and methods: We reviewed patients who underwent ESD for solitary early gastric cancer located on the greater curvature of the gastric body from January 2003 to September 2014. The technical results of ESD were compared between the group treated with the novel near-side approach method and the group treated with the conventional method. Results: This study included 238 patients with 238 lesions, 118 of which were removed using the near-side approach method and 120 of which were removed using the conventional method. The median procedure time was 92 minutes for the near-side approach method and 120 minutes for the conventional method. The procedure time was significantly shorter in the near-side approach method arm. Although, the procedure time required by an experienced endoscopist was not significantly different between the two groups (100 vs. 110 minutes), the near-side approach group showed significantly shorter procedure time for a less-experienced endoscopist (90 vs. 120 minutes). Conclusions: The near-side approach method appears to require less time to complete gastric ESD than the conventional method using IT knives for technically challenging lesions located on the greater curvature of the gastric body, especially if the procedure is performed by less-experienced endoscopists.

to evaluate the thickness of the gastric wall at the time of intra gastric balloon (IGB) placement, at the time of its withdrawal and one month after withdrawal.: fifteen morbidly obese patients underwent the introduction of IGB under general anesthesia. In all patients, there was infusion of 500ml of distilled water in the balloon for the test. Measurements of the thickness of the gastric wall were made in the antrum, body and proximal body, using a radial echoendoscope with a frequency of 12MHz and maximum zoom, and its own balloon inflated with 5ml of distilled water.: the presence of IGB led to increased wall thickness of the gastric body by expanding the muscle layer. These changes were apparently transient, since 30 days after the balloon withdrawal there was a tendency to return of the wall thickness values ​​observed before the balloon insertion.: the use of intragastric balloon for the treatment of obesity determines transient increase in the wall thickness of the gastric body caused by expanded muscle layer.avaliar a espessura da parede gástrica no momento do posicionamento do balão intragástrico (BIG), no momento de sua retirada e um mês após a retirada.quinze pacientes obesos mórbidos foram submetidos à introdução de BIG sob anestesia geral.

Os procedimentos minimamente invasivos e principalmente aqueles que utilizam a tecnologia robótica permitiram o desenvolvimento de novas abordagens, incluindo o acesso retroauricular, que agora é usado rotineiramente, especialmente na Coréia do Sul. A presente nota irá ilustrar a técnica e a experiência inicial na América Latina, demonstrando que esta abordagem é viável, segura e eficaz oncologicamente, podendo ser utilizada em casos selecionados com um benefício estético evidente.

Gastric confirmation by pH is only achievable in approximately 50% of placements and X-rays are expensive and may be misinterpreted. Bedside electromagnetic (EM) guidance offers real-time confirmation. The authors determined the accuracy of guidance in predicting gastric body position from the EM trace using official Cortrak guidance (the EM trace reaches the bottom left quadrant of the anterior screen) compared with local guidance (detailed anterior-depth description of the GI flexures). X-ray, pH or an EM trace beyond the gastric body were used to independently confirm gastric position. Of 496 EM traces, 49% of tubes were in the oesophagus on entry to the lower left quadrant whereas 12% had already reached the gastric body in the upper left quadrant. Overall, predicting position by quadrant was 70% accurate whereas differentiating the pre-gastro-oesophageal junction (pre-GOJ) from the gastric body flexure was 100% accurate. Confirming gastric position by the anterior trace quadrant appears to be unsafe whereas expert differentiation of the pre-GOJ and gastric body flexures was reliable. The authors invite Corpak Medsystems (now owned by Halyard Health) to update its guidance in view of these findings.

We describe the case of a man with fundic gland polyposis associated with proton-pump inhibitor (PPI) use. Some investigators have reported an association between long-term PPI use and an increase in the risk of developing fundic gland polyps (FGPs). These FGPs are considered to be reversible on stopping PPI treatment. The current patient had used a PPI for 10 years, resulting in multiple FGPs in his gastric body. However, 6 months after cessation of the PPI, the FGPs had obvously regressed, even though a histamine-2 receptor antagonist had subsequently been prescribed. This case demonstrates a link between PPI treatment and FGPs. LEARNING POINTS Long-term proton-pump inhibitor (PPI) use can increase the risk of developing fundic gland polyps (FGPs). This phenomenon is thought to be reversible, and a few case reports have demonstrated spontaneous resolution of FGPs after cessation of PPI use. When fundic gland polyposis is detected, a family history of polyposis and a history of PPI use should both be sought.

Cystic Brunner’s gland hamartoma has been described under the various names including cystic hamartoma of Brunner’s glands, cystic Brunner’s gland heterotopia, Brunner’s gland cysts, Brunner’s gland cystadenoma, Brunner’s cyst, mucocele of Brunner’s glands, and cyst of Brunner’s glands. 1-4 Here, we report a rare case where a patient presented with an incidentally found, and long-standing pedunculated submucosal mass in the stomach body, which was diagnosed as a cystic Brunner’s gland hamartoma. To the best of our knowledge, no previous occurrence of cystic Brunner’s gland hamartoma in the

A 7-year-old spayed female domestic shorthair cat was referred for chronic intermittent vomiting. The frequency of vomiting increased recently, and the cat showed anorexia at presentation. There were no remarkable abnormalities on the blood analyses and diagnostic imaging. However, the endoscopic examination revealed focal erosions of the gastric body mucosa, and subsequent multiple biopsies were obtained. Histopathologic examination indicated mild to moderate lymphocytic gastritis. The vomiting was completely disappeared 7 days after the administration with prednisolone (PDS). However, because of side effects caused by the long-term PDS administration, cyclosporine was added on the prescription with tapered dose of PDS. The dog’s condition improved with continued cyclosporine treatment, and no further vomiting and anorexia episodes have been noted. This case describes the successful management with administration of cyclosporine in feline lymphocytic gastritis.

Background and Aim Effectiveness of capsule endoscopy (CE) for screening the small bowel in patients with portal hypertension (PHT) has been reported. However, few reports discuss CE detection of specific esophagogastric lesions related to PHT. Thus, we assessed whether CE is useful for detecting such lesions. Methods One hundred nineteen consecutive patients with PHT comprised the study group. All had undergone esophagogastroduodenoscopy (EGD) prior to CE. The diagnostic yield of CE for esophageal varices (EVs), gastric varices (GVs), and portal hypertensive gastropathy (PHG) was evaluated. In addition, diagnostic yield in relation to form, location of the varices, grade, and extent of PHG was evaluated. Results EVs were found by EGD in 71 patients. The overall diagnostic yield of CE for EVs was 72% (51/71). The diagnostic yield was significantly greater for F2/F3 EVs than for F1 EVs (87% vs 61%, P = 0.03). The diagnostic yield was significantly greater for Lm/Ls EVs than for Li EVs (85% vs 55%, P = 0.01). The diagnostic yield was significantly greater for locus superior/locus medialis EVs than for locus inferior EVs (85% vs 55%, P = 0.01). GVs were found by EGD in 29 patients. Only one case was detected by CE. PHG was found by EGD in 35 patients. The diagnostic yield of CE for PHG was 69% (24/35). There was no difference in diagnostic yield between cases of severe and mild PHG (82% vs 63%, P = 0.44). Diagnostic yield of CE for PHG in the gastric body was significantly greater than that in the fundus (100% vs 48%, P = 0.0009). Conclusion CE is reliable for diagnosis of F2/F3 and/or Lm/Ls EVs and of PHG in the gastric body.

Esophagogastroduodenoscopic examination shows diffuse redness of the mucosa of the gastric body, which can be identified as a deep reddish color. The present case underscores the importance of diffuse redness as a key endoscopic feature that enables prompt diagnosis of current Helicobacter pylori infection.

Closure of gastrotomy remains a major barrier to clinical application of NOTES. Full-thickness closure of gastrotomy using endoscopic suturing device is presumed to be safer than that by endoclips. We evaluated the safety and feasibility of closing gastrotomy by Eagle Claw VIII, endoclips, and surgical suturing. Fifty-one ex vivo porcine stomach models were included with 17 closures per arm. A 2-cm linear incision was created at the gastric body using scalpel externally. The time for gastrotomy closure, pneumatic bursting pressure, site of air leakage and number of suturing, or clips used were recorded. In addition, the technical difficulties of closure using Eagle Claw VIII and endoclips were assessed by a quantitative scale. All gastrotomies were successfully closed without leakage upon full gaseous distension. Closure time of Eagle Claw VIII was significantly longer than that of endoclips and surgical suturing. The median pneumatic bursting pressures were 56 (range 35–110) mmHg for Eagle Claw VIII, 19 (range 9–65) mmHg for endoclips, and 78 (range 63–110) mmHg for surgical suturing. The bursting pressures for surgical suturing and Eagle Claw VIII were significantly higher than that of endoclips (P

A 37-year-old female presented to our hospital with the complaint of abdominal distension for one month. A gastroscopy examination showed extensive chyme retention and varying erosion and ulceration of the gastric body. The pathology showed moderate chronic inflammation and erosion of the gastric body mucosa, with accompanying Helicobacter pylori infection. She accepted treatment for one month. The patient then accepted to undergo endoscopic ultrasonography, which showed that normal structure of the gastric body intumescence was discernible. The pathology showed chronic mild-moderate inflammation of the gastric body mucosa associated with interstitial amyloidosis, with accompanying Helicobacter pylori infection. She accepted treatment for the eradication of Helicobacter pylori, and the original ulcer healed.

Trichobezoars are hairballs or hair-like fibers formed by chewing and swallowing hair or any other indigestible materials. Trichobezoars usually form in the gastric body and are thus prepyloric. However, trichobezoars may rarely pass through the pylorus into the duodenum, jejunum, ileum, and even the colon, in a condition referred to as Rapunzel syndrome. Here, we present a case of a 13-year-old girl with this rare syndrome and discuss the diagnosis and treatment of the disease.

Gastric gastrointestinal stromal tumors (GIST) have a distinct surgical therapy compared to gastric adenocarcinoma. Large oncologic margins and lymphadenectomy are not necessary rendering local resections suitable to treat the disease and spare the stomach. That may be accomplished through a minimally invasive approach. We present a case of a 67-year-old woman with an endophytic 3.5 cm gastric GIST located in the posterior wall of the gastric body that underwent an endogastric resection. Operation was uneventful. The patient was discharged in the following day. Pathologic examination showed free margins and a low grade GIST. Endogastric resection is a feasible option in endophytic GISTs located in the posterior wall of the stomach.

Background After an acute attack of pancreatitis, walled-off pancreatic fluid collections (PFC) occur in approximately 10 % of cases. Drainage of the cavity is recommended when specific indications are met. Endoscopic drainage has been adopted as the main intervention for symptomatic walled-off PFC. Altered gastric anatomy in these patients poses an interesting challenge. We present the first case of a patient with sleeve gastrectomy who underwent successful endoscopic transduodenal necrosectomy (TDN). Case presentation Forty year old woman with history of morbid obesity status post sleeve gastrectomy in 2009 was found to have symptomatic gallstone disease complicated by severe necrotizing gallstone pancreatitis and further complicated by symptomatic walled off pancreatic necrosis (WOPN). Imaging significant for 10.8 × 7.6 cm fluid collection with necrotic debris in the body and tail of the pancreas and endoscopic necrosectomy was attempted. EGD showed tubular gastric body and antrum, with extrinsic compression in the antrum and duodenal bulb from the pancreatic cyst. Duodenal bulb was selected as the preferred fistula site due to sleeve gastrectomy. Patient underwent successful TDN in two sessions. Patient had symptomatic improvement at follow-up with resolution of WOPN. Conclusion To our knowledge, this is the first reported case of EUS-guided endoscopic necrosectomy in a patient with sleeve gastrectomy. The duodenal approach was used in our patient due to history of sleeve gastrectomy.

A case report in which endoscopic attempts at SEMS placement for a stenosing gastric body tumour was not possible using the Seldinger technique, due to difficulty manoeuvring it past an acute angle. A novel technique that was devised to overcome such difficulties is described in this paper.

A small depressed lesion is located on the posterior side of greater curvature of the gastric body.

Spontaneous regression (SR) of malignancy is a rare phenomenon, especially in patients with gastric cancer. A 77-year-old male, who was already diagnosed with gastric adenocarcinoma by endoscopic biopsy from a private clinic, was referred to our hospital. Despite our strong recommendation, the patient refused surgical therapy. A follow-up endoscopy was performed 3 months later, which revealed that the ulcer had changed into a white scar. Endoscopic biopsy revealed only chronic inflammation. Two and 6 years later, cancer recurred, and SR was confirmed both times, histologically, at the gastric body. The patient is still alive without any gastrointestinal symptoms after 13 years of follow-up. The cause of SR is yet uncertain and there are only a few suggestions of scientific mechanisms. We, herein, report this very rare case of repeated recurrence and SR of gastric cancer without clear cause.

Background and objective: the prevalence of gastric polyps in esophagogastroduodenoscopies (EGDs) ranges between 0.33 and 6.35%. The relative frequency of histological subspecies varies widely among published series. The objective is to describe the endoscopic and histological characteristics of the polypoid lesions, and to study possible associations. Material and methods: we retrospectively revised the EGDs done in our center in 2009. Demographic, endoscopic and histological data were gathered. We proceeded to a descriptive analysis and studied possible associations. Results: gastric polypoid lesions were found in 269 of the 6307 (4.2%) reviewed EGDs, 61% were found in women. Mean age was 64.93 years (SD: ±15.23). A single polyp was found in 186 patients (69.1%), over 10 lesions appeared in 31 (11.5%). An estimated size of ≤ 3 mm was found in 108 lesions (37.2%) and greater than 10 mm in 52 cases (17.9%). Most lesions were sessile (90.8%). The location of 34.8% was the gastric antrum, 39.3% were found in the gastric body and 25.9% were in the fundus. Chronic gastritis was confirmed in 53.5% of the patients and 46.5% had received protom pump inhibitors (PPIs). Histopathological diagnosis was: hyperplastic polyps 50.9%, fundic gland polyps 7.4%, adenomas 3%, adenocarcinomas 1.9% and normal mucosa 29.7%. We found no significant association between the histopathological type of lesions and the use of proton pump inhibitor. Conclusions: we found polypoid lesions in 4.2% of the EGDs. The most frequent histopathological findings were hyperplastic polyps (50.9%), followed by fundic gland polyps (7.4%), adenomas (3%), and adenocarcinomas (1.9%).

Calcifying fibrous pseudotumour (CFPT) is a rare lesion that has only recently been reported in the literature. Usually, the lesion develops in subcutaneous tissue, deep soft tissues or viscera. It appears as a uniform, hypocellular and well-circumscribed mass without a capsule. Only nine cases of gastric CFPT have been reported in the literature so far. Here, we report a new case of gastric CFPT, which was, surprisingly, associated with an ulcer. To our knowledge, a gastric CFPT with an ulcer has not been previously reported in the literature. The patient (a healthy 49-year-old man) had vomited approximately 300 g brown liquid and developed syncope once. CT scan and gastroscopy revealed a polypoid mass at the great curvature of the gastric body with a larger ulcer on its top. The mass was removed by surgery. During a follow-up of 5 months, the patient was asymptomatic with no recurrence. We discuss the imaging findings, as well as the clinicopathological features of this unusual case and review the related literature.

症例は2005年に左乳癌に対し胸筋温存乳房切除術を施行後，外来通院中の74歳女性．定期検査にて施行した胸部単純CT検査にて胃壁から胃壁外と思われる部位に線状異物を認めるも，検査時には異物の存在を指摘できず，症状がなかったため帰宅した．10日後の定期受診時に異物の存在に気付き，再度CT検査を施行した．前回と同部位に線状異物を認めたため，上部消化管内視鏡検査を施行するも異物は確認できず，胃体下部小弯後壁に不良肉芽を認めるのみであった．CT検査と合わせて異物による消化管穿通と診断し手術を施行した．術中所見では胃体下部小弯から前庭部後壁にかけて一度胃角を貫いた状態で再度胃壁へ穿通している50mmの魚骨を確認した．胃壁外は肉芽組織に覆われており腹腔内への露出は認めなかった．本症例のように異物が胃内から腹腔内へ穿通後，再度胃へ穿通した症例報告は存在せず，きわめてまれであり文献的考察を加え報告する．

The incidence of endocrine tumors of the stomach is increasing. Most gastric endocrine tumors are well-differentiated neoplasms of enterochromaffin-like cells, the major endocrine cell type of the gastric body and fundus. These gastric carcinoids (GCs) show relatively uniform cells with a l

The factors underlying the survival and maintenance of interstitial cells of Cajal (ICC) are not well understood. Loss of ICC is often associated with loss of neuronal nitric oxide synthase (nNOS) in humans, suggesting a possible link. The aim of this study was to determine the effect of neuronal NO on ICC in the mouse gastric body. The volumes of ICC were determined in nNOS(-/-) and control mice in the gastric body and in organotypic cultures using immunohistochemistry, laser scanning confocal microscopy and three-dimensional reconstruction. ICC numbers were determined in primary cell cultures after treatment with an NO donor or an NOS inhibitor. The volumes of myenteric c-Kit-immunoreactive networks of ICC from nNOS(-/-) mice were significantly reduced compared with control mice. No significant differences in the volumes of c-Kit-positive ICC were observed in the longitudinal muscle layers. ICC volumes were either decreased or unaltered in the circular muscle layer after normalization for the volume of circular smooth muscle. The number of ICC was increased after incubation with S-nitroso-N-acetylpenicillamine and decreased by N(G)-nitro-L-arginine. Neuronally derived NO modulates ICC numbers and network volume in the mouse gastric body. NO appears to be a survival factor for ICC. ispartof: Neurogastroenterology and motility vol:19 issue:7 pages:585-595 ispartof: location:England status: published

Undernutrition has been associated with gut mucosal atrophy, impaired absorption, and increased permeability. This study investigated the effect of severe undernutrition and subsequent refeeding on gastric and duodenal mucosal protein fractional syntheses (MPFS).MPFS was investigated in the gastric body, antrum, and duodenum of 23 severely undernourished patients by means of (14)C-leucine incorporation into tissue protein and repeated after a period of refeeding. Results were evaluated in comparison with a group of 22 healthy controls and presented as mean +/- standard error of the mean.The mean body index of the undernourished patients was 13.29 +/- 0.33 kg/m(2) versus 22.67 +/- 0.63 kg/m(2) in the controls (P0.001). MPFS in the controls and undernourished patients were similar (gastric body, 36.49 +/- 2.88 versus 33.41 +/- 3.08%/d; gastric antrum, 25.51 +/- 2.20 versus 24.95 +/- 2.32%/d; duodenum, 25.90 +/- 2.58 versus 25.49 +/- 1.99%/d). After refeeding, the body mass index of the undernourished patients increased to 15.87 +/- 0.44 kg/m(2) (P0.001). The MPFS increased significantly (gastric body, 51.80 +/- 8.12%/d, P0.05; gastric antrum, 33.44 +/- 3.66%/d, P0.05; duodenum, 46.27 +/- 8.02%/d, P0.01), with the MPFS of the duodenum significantly greater than the control values (P = 0.01).Despite severe undernutrition, MPFS of the gastric body, antrum, and duodenum remained similar to control values. Enteral feeding resulted in a significant increase in MPFS, indicating a trophic response.

The diagnosis of Helicobacter pylori (H. pylori) infection is usually based on the results of urease test and histology. The urease test known as a simple and cheap method does not need special skills to perform or to read the result. The time needed for the test to turn positive depends on the concentration of bacteria, and the accuracy is up to the density of H. pylori density in the biopsy sample, which is generally lower in children than adolescents and adults. Therefore, there are debates about the sensitivity of the urease test in children. The reason for lower sensitivity of the urease test in children was not identified, but might be related to the low density and patchy distribution of bacteria. In this review, we discuss the limitations of the urease test in children according to age, histology, number of biopsy samples, and biopsy site. In children under 5 years old, the differences in positivity rate when the urease test used one or three biopsy samples, and samples from the antrum or the gastric body, were larger than those in children aged 5-15 years. Thus, three or more biopsy samples from both the antrum and body would improve the sensitivity of H. pylori infection diagnosis in children under 5 years old.

Background/Aim: There are currently no data on the relative retention rates of the Instinct clip, Resolution clip, and QuickClip2Long. Also, it is unknown whether retention rate differs when clips are applied to ulcerated rather than normal mucosa. The aim of this study is to compare the retention rates of three commonly used endoscopic clips. Materials and Methods: Six pigs underwent upper endoscopy with placement of one of each of the three types of clips on normal mucosa in the gastric body. Three mucosal resections were also performed to create "ulcers." Each ulcer was closed with placement of one of the three different clips. Repeat endoscopy was performed weekly for up to 4 weeks. Results: Only the Instinct and Resolution clips remained attached for the duration of the study (4 weeks). At each time point, a greater proportion of Instinct clips were retained on normal mucosa, followed by Resolution clips. QuickClip2Long had the lowest retention rate on normal mucosa. Similar retention rates of Instinct clips and Resolution clips were seen on simulated ulcers, although both were superior to QuickClip2Long. However, the difference did not reach statistical significance. All QuickClip2Long clips were dislodged at 4 weeks in both the groups. Conclusions: The Resolution and Instinct clips have comparable retention rates and both appeared to be better than the QuickClip2Long on normal mucosa-simulated ulcers; however this did not reach statistical significance. Both the Resolution clip and the Instinct clip may be preferred in clinical situations when long-term clip attachment is required, including marking of tumors for radiotherapy and anchoring feeding tubes or stents. Either of the currently available clips may be suitable for closure of iatrogenic mucosal defects without features of chronicity.
