    Asian J Surg, 2017 Sep;40(5):407-414.
    PMID: 26922628 DOI: 10.1016/j.asjsur.2015.12.001
    OBJECTIVE: Intraluminal gastric gastrointestinal stromal tumors (GISTs) located at the posterior wall and near the gastroesophageal junction represent a surgical challenge. We present our experience of laparoscopic transgastric resection for gastric GISTs of such location.

    METHODS: Data of seven patients undergoing laparoscopic transgastric resection were identified and retrospectively reviewed with regard to procedural steps and patient outcomes.

    RESULTS: Seven patients (4 men; mean age 64.1 ± 14.6 years) with gastric GISTs underwent laparoscopic transgastric resection from January 2010 to May 2015. Three of the seven GISTs were located near the gastroesophageal junction and the rest were found in the posterior wall of the stomach. All seven patients underwent successful laparoscopic resection without any conversions. There were no mortalities and no significant postoperative complications. Intraoperative endoscopy was performed for all patients. The mean operative time was 164.0 ± 59.1 minutes. Regular diet was resumed within 3 days on average and mean postoperative stay was 3.6 ± 1.3 days. All patients achieved complete R0 resection with a mean tumor size of 5.5 ± 1.1 cm. At a mean follow-up of 48.0 ± 13.4 months, all patients were recurrence free.

    CONCLUSIONS: GISTs of the posterior wall and in close proximity to the gastroesophageal junction can be safely resected laparoscopically using such an approach. Standard technique is required to achieve good oncological outcomes.

  2. The efficacy of blueberry and grape seed extract combination on triple therapy for Helicobacter pylori eradication: a randomised controlled trial
    Chua CS, Yang KC, Chen JH, Liu YH, Hsu YH, Lee HC, et al.
    Int J Food Sci Nutr, 2016 Mar;67(2):177-83.

    Helicobacter pylori is a major risk factor for gastritis, gastric ulcers and gastric cancer. Traditional therapy with proton pump inhibitor and antibiotics is regarded as optimal for H. pylori eradication whereas, the eradication rate is unsatisfactory. Studies have reported that cranberry may inhibit H. pylori adhesion to the human gastric mucus but lack of other berry extracts have been evaluated in clinical study. Thus, a 9-week add-on randomised controlled trial was conducted to explore the impact of blueberry and grape seed extract (BGE) combinations traditional therapy for H. pylori eradication. In results, we found that there was no significant difference of eradication rate between the berry extract group and placebo group in the intention-to-treat analysis and in the per-protocol analysis (94.64% versus 84.62%, p = 0.085). Diarrhoea, constipation and epigastric pain were observed increasing during ingestion of the berry extract in some cases. In conclusion, this study indicated that no significant difference existed between the BGE extract group and placebo group in eradication rate under triple therapy.

  4. Bochdalek diaphragmatic hernia presenting with acute gastric dilatation
    Quah BS, Hashim I, Simpson H
    J Pediatr Surg, 1999 Mar;34(3):512-4.
    PMID: 10211672
    Congenital diaphragmatic hernia through the foramen of Bochdalek may present after infancy. A 21/2-year-old Malay girl presented with acute respiratory distress. Chest examination showed reduced chest expansion and decreased breath sounds on the left side. Chest radiograph showed a large "cyst" in the left chest, which was thought to be a lung cyst under tension. Tube thoracostomy resulted in clinical improvement. Results of a barium study showed that the cyst perforated by the thoracostomy tube was the stomach, which had herniated through a Bochdalek diaphragmatic defect. Surgical repair of the diaphragmatic defect and closure of the perforated stomach was performed successfully. Congenital diaphragmatic hernia should be included in the differential diagnosis of respiratory distress in young children. Nasogastric tube placement must be considered as an early diagnostic or therapeutic intervention when the diagnosis is suspected.

  5. Fulltext Perforated malignant gastric ulcer in a pregnant young adult: a case report
    Jasmi AY, Normala B, al-Amin MD
    Med J Malaysia, 2000 Mar;55(1):135-7.
    PMID: 11072499
    Gastric cancer in the young adult is rare and has been said to be more aggressive than gastric cancers of the older age group. Its unique association with pregnancy is even rarer. However, they have similar complications of haemorrhage, obstruction and perforation. We report a 27 year old lady at 16 weeks gestation who presented with a perforated malignant gastric ulcer and carcinomatosis peritonei. Reviewing the literature, we realised that such complication of a gastric cancer occurring in a pregnant young adult has not been previously documented.

    PMID: 9322300
    Strongyloides stercoralis infection is of low prevalence in Malaysia. We report an unusual case presenting primarily with gastric symptoms. The patient was a 72 years old Chinese male admitted for progressive weight loss and abdominal bloating. Gastroscopic examination revealed mucosal prepyloric elevations in the gastric mucosa. Gastric strongyloidiasis was confirmed by the presence of adult forms, as well as ova and larval rhabditiform stages of the worm in the gastric mucosal crypts. We believe that this is the first histologically documented case of gastric strongyloidiasis in Malaysia.

  7. Fulltext Twice daily cimetidine in the initial treatment of chronic gastric ulcer--a double-blind placebo-controlled trial
    Tay HH, Yap I, Guan R, Koh PS, LaBrooy SJ, Kang JY
    Med J Malaysia, 1988 Jun;43(2):181-5.
    PMID: 3070309
    Thirty-one patients with endoscopically proven chronic gastric ulcer completed a randomised double-blind trial comparing the effects of cimetidine and placebo on ulcer healing. Seventeen patients received cimetidine 400 mg bid and 14 patients received placebo. Repeat endoscopy at six weeks showed that the ulcer had healed in 12 patients (71%) receiving cimetidine and in four patients (29%) receiving placebo (p=O.032). Non-smokers healed their ulcers better than smokers (83% vs 35%, p=O.023). The use of cimetidine was not associated with any adverse effects.

  8. Omeprazole in acute and long-term treatment of Asian patients with peptic ulcer refractory to H2-antagonists
    Chelvam P, Wong EC
    J Gastroenterol Hepatol, 1989;4 Suppl 2:75-81.
    PMID: 2577478
    Twenty-seven patients with peptic ulcer (19 with duodenal ulcer (DU) and eight with gastric ulcer (GU] refractory to H2-antagonists were treated with 40 mg of omeprazole once daily for 4-8 weeks, depending on the rate of ulcer healing. Clinical assessment, endoscopy and laboratory tests were performed at entry, after 2 and after 4 weeks, and if unhealed, also after 8 weeks' treatment. Ten healed patients were given a maintenance therapy of omeprazole 20 mg daily for up to 12 months during which the patients returned for endoscopy, gastric biopsy and laboratory tests at 3-monthly intervals. The initial treatment healed 15 of 19 (79%) DU patients in 2 weeks and all DU patients by 4 weeks. Seven of eight (87%) GU patients healed in 4 weeks and only one required 8 weeks' treatment. Symptom relief was rapid, with most patients being symptom-free within the first day of treatment. Six patients received 12 months' continuous maintenance therapy, one patient 9 months and three patients 6 months' treatment. All patients remained in remission whilst on omeprazole therapy. No adverse events were reported throughout the study. There were no clinically significant changes in haematology or blood chemistry after healing or during the long-term treatment. Biopsy samples revealed no histological changes in the gastric mucosa at any stage. Omeprazole 40 mg therefore was found to produce rapid healing and symptom relief in Asian patients with H2-antagonist-resistant peptic ulcers. Maintenance therapy with omeprazole 20 mg daily was shown to be safe and effective in preventing recurrence of peptic ulceration.

    PMID: 1025748
    The recovery of six adult Gnathostoma spinigerum Owen, 1936 from a civet cat, Prionodon linsang Hardwick, constitutes the second reported record of this parasite and the first authenticated case of adult worms found in a wild animal from Malaysia. The food habits of the infected P. linsang as an important link in the transmission of G. spinigerum in the intermediate and definitive hosts together with the probable distribution of this parasite are discussed.

    Teng YS, Jehan S, Lie-Injo LE
    Hum Genet, 1979;53(1):87-90.
    PMID: 395099
    Human alcohol dehydrogenase ADH2 and ADH3 were investigated in liver and stomach specimens of Chinese and Indians from West Malaysia. Eight-nine percent of the Chinese carry the atypical ADH2 type, a proportion very similar to that reported in Japanese. However, among 43 Indian specimens there was not a single case of atypical ADH2. In Indians, the gene frequency of ADH13 is 0.64 and of ADH23 0.36, similar to the frequencies in Caucasians, whereas in Chinese, the gene frequency for ADH13 and ADH23 is 0.91 and 0.09, respectively. We also report some unusual enzymatic characteristics in the course of our study.

    PMID: 32918440
    Gastric leiomyoma of the antrum intussuscepted into first part of the duodenum is a rare complication. We report here an 80-year-old woman who presented at the Sarawak General Hospital, Kuching, Sarawak, Malaysia with early satiety and epigastric fullness for 3 months. She had no prior medical or surgical history other than an uneventful open cholecystectomy. Upper endoscopy showed a large submucosal mass in the first part of duodenum with pyloric converging gastric folds. Computed tomography scan of the abdomen showed a gastroduodenal intussusception with a 4x6cm mass at the junction between the first and second part of duodenum. Laparoscopic transgastric resection was performed. Histopathological examination of the resected specimen confirmed leiomyoma. She remained well at 43 months follow-up.

    Int J Med Mushrooms, 2016;18(12):1093-1104.
    PMID: 28094747 DOI: 10.1615/IntJMedMushrooms.v18.i12.40
    The aim of this study was to determine the antiulcer activity of Lignosus rhinocerotis in rats. A total of 48 Sprague-Dawley rats were used in ethanol-induced, aspirin-induced, and water immersion-restraint stress-induced ulcer models. Rats were equally divided into 4 groups for each model and orally administered 5 mL/kg distilled water, 20 mg/kg omeprazole, as well as 250 and 500 mg/kg of L. rhinocerotis powder. L. rhinocerotis powder at both 250 and 500 mg/kg doses demonstrated significant (P < 0.05) protection against gastric ulceration in all the induced ulcer models. Histological studies revealed severe damage and hemorrhage of gastric mucosa in the negative control group for all ulcer-induced models. The study suggests that L. rhinocerotis powder possesses dose-dependent antiulcer activity in the gastric mucosa, as ascertained grossly and histologically, compared with the negative control groups.

  16. Safety and efficacy of endoscopic submucosal dissection of large (≥3 cm) subepithelial tumors located in the cardia
    Li J, Tang J, Lua GW, Chen J, Shi X, Liu F, et al.
    Surg Endosc, 2017 12;31(12):5183-5191.
    PMID: 28597288 DOI: 10.1007/s00464-017-5585-y
    BACKGROUND: Upper gastrointestinal subepithelial tumors (SETs) may harbor potential malignancy. Although it is well recognized that large SETs should be resected, the treatment strategy remains controversial. Compared to surgical resection, endoscopic resection has many advantages such as less invasive, shorter hospital stay, lower costs, and better quality of life. However, Endoscopic resection of large SETs in the cardia is challenging. The purpose of this study was to evaluate the safety and efficacy of endoscopic submucosal dissection (ESD) in the treatment of such SETs.

    METHODS: A total of 41 patients with large SETs (≥3 cm in diameter) located in the cardia were involved in the study. All patients underwent ESD. Data on therapeutic outcomes and follow-up were collected, for analysis of risk factors of complication rates.

    RESULTS: The average tumor size was 4.7 ± 1.7 cm. The average procedure time was 69.3 ± 32.7 min and the average postoperative hospital stay was 3.5 ± 1.1 days. A total of 41 tumors were removed successfully, in which 35 were leiomyomas, three were gastrointestinal stromal tumors, two were lipomas, and one was gastritis cystica profunda. The en bloc resection rate was 90.2%, and was significantly higher for tumors with a round or oval shape (100%) than for those with an irregular shape (75.0%) (P

  17. Greater gastric interoception is associated with more positive body image: Evidence from adults in Malaysia and the United Kingdom
    Todd J, Aspell JE, Barron D, Toh EKL, Zahari HS, Mohd Khatib NA, et al.
    Body Image, 2020 Sep;34:101-111.
    PMID: 32512525 DOI: 10.1016/j.bodyim.2020.05.011
    Gastric interoception refers to the processing of sensory stimuli originating in the gut. Previous research has found that gastric interoception (measured using a water load task) is associated with drive for thinness in young Western women. However, associations with broader facets of body image and in diverse national groups have not been previously investigated. To address these issues, we asked samples of adults in the United Kingdom (UK; N = 91, women n = 54) and Malaysia (N = 100, women n = 50) to complete a 2-stage water load task (WLT) and measures of positive body image (i.e., body appreciation, functionality appreciation). The results indicated that a greater change in the intensity of self-reported WLT-related sensations was associated with significantly higher body appreciation and functionality appreciation after accounting for gender identity, body mass index, and national group. Behavioural performance on the WLT was significantly associated with body appreciation and functionality appreciation for the Malaysian sample, but not the UK adults, after accounting for gender identity and body mass index. These findings extend previous research by demonstrating that there are significant associations between facets of gastric interoception and previously unexplored facets of body image in both Western and non-Western settings.

  18. Association of IGF-1 and IGFBP-3 levels with gastric cancer: A systematic review and meta-analysis
    Liu H, Gu H, Kutbi EH, Tan SC, Low TY, Zhang C
    Int J Clin Pract, 2021 Nov;75(11):e14764.
    PMID: 34469629 DOI: 10.1111/ijcp.14764
    PURPOSE: Many studies have investigated the association between serum IGF-1 and IGFBP levels with gastric cancer (GC), but the results remained inconclusive. In this work, we performed a systematic review and meta-analysis to examine the precise association of serum levels of IGF-1 and IGFBP with GC.

    METHODS: A comprehensive systematic search was carried out in PubMed/MEDLINE, SCOPUS, Web of Science, and EMBASE databases for (nested) case-control studies that reported the levels of IGF-1 and IGFBP in GC cases and healthy controls, from inception until October 2020. Weighted mean difference (WMD) was calculated for estimating combined effect size. Subgroup analysis was performed to identify the source of heterogeneity among studies.

    RESULTS: We found eight and five eligible studies (with 1541 participants) which provided data for IGF-1 and IGFBP, respectively. All studies on IGFBP reported the IGFBP-3 isoform. The pooled results indicate that GC patients had significantly lower serum IGF-1 [WMD = -26.21 ng/mL (95% CI, -45.58 to -6.85; P = .008)] and IGFBP-3 [WMD = -0.41 ng/mL (95% CI, -0.80 to -0.01; P = .04; I2  = 89.9%; P

  19. Fulltext Apparent diet digestibility of captive colobines in relation to stomach types with special reference to fibre digestion
    Hoshino S, Seino S, Funahashi T, Hoshino T, Clauss M, Matsuda I, et al.
    PLoS One, 2021;16(9):e0256548.
    PMID: 34543310 DOI: 10.1371/journal.pone.0256548
    Colobine monkeys are known for the anatomical complexity of their stomachs, making them distinct within the primate order. Amongst foregut fermenters, they appear peculiar because of the occurrence of two different stomach types, having either three ('tripartite') or four ('quadripartite', adding the praesaccus) chambers. The functional differences between tri and quadripartite stomachs largely remain to be explained. In this study, we aim to compare the apparent digestibility (aD) in tripartite and quadripartite colobines. Hence, we measured the aD in two colobine species, Nasalis larvatus (quadripartite) and Trachypithecus cristatus (tripartite), in two zoos. We also included existing colobine literature data on the aD and analysed whether the aD of fibre components is different between the stomach types to test the hypothesis of whether quadripartite colobines show higher aD of fibre components than tripartite colobines did. Our captive N. larvatus specimen had a more distinctively varying nutrient intake across seasons with a larger seasonal variation in aD than that of a pair of T. cristatus, which mostly consumed commercial foods with a lower proportion of browse and less seasonal variation. We observed higher aD of dry matter (DM), neutral detergent fibre (NDF) and acid detergent fibre (ADF) in the N. larvatus specimen, suggesting a higher gut capacity of N. larvatus provided by the additional praesaccus forestomach chamber. Based on the analysis of literature data for aD, we also found that quadripartite species achieved higher fibre digestibility at similar dietary fibre levels compared with tripartite species, supporting the hypothesis that the additional gut capacity offered by the praesaccus facilitates a longer retention and hence more thorough microbial fermentation of plant fibre.

  20. Fulltext Dysbiosis of the microbiome in gastric carcinogenesis
    Castaño-Rodríguez N, Goh KL, Fock KM, Mitchell HM, Kaakoush NO
    Sci Rep, 2017 11 21;7(1):15957.
    PMID: 29162924 DOI: 10.1038/s41598-017-16289-2
    The gastric microbiome has been proposed as an etiological factor in gastric carcinogenesis. We compared the gastric microbiota in subjects presenting with gastric cancer (GC, n = 12) and controls (functional dyspepsia (FD), n = 20) from a high GC risk population in Singapore and Malaysia. cDNA from 16S rRNA transcripts were amplified (515F-806R) and sequenced using Illumina MiSeq 2 × 250 bp chemistry. Increased richness and phylogenetic diversity but not Shannon's diversity was found in GC as compared to controls. nMDS clustered GC and FD subjects separately, with PERMANOVA confirming a significant difference between the groups. H. pylori serological status had a significant impact on gastric microbiome α-diversity and composition. Several bacterial taxa were enriched in GC, including Lactococcus, Veilonella, and Fusobacteriaceae (Fusobacterium and Leptotrichia). Prediction of bacterial metabolic contribution indicated that serological status had a significant impact on metabolic function, while carbohydrate digestion and pathways were enriched in GC. Our findings highlight three mechanisms of interest in GC, including enrichment of pro-inflammatory oral bacterial species, increased abundance of lactic acid producing bacteria, and enrichment of short chain fatty acid production pathways.
