    BACKGROUND: Standard polypectomy techniques may be contributing to ineffective eradication of colonic superficial neoplasia, an increasing number of which are nonpolypoid. We aimed to demonstrate the practicality and efficacy of the "inject and cut" endoscopic mucosal resection (EMR) technique in routine clinical practice.

    METHODS: Colonic EMRs performed for polypoid and nonpolypoid lesions at a tertiary institution were prospectively collected and analyzed for efficacy, and short and long-term complications.

    RESULTS: 224 colonic neoplasms (143 flat, 65 sessile and 16 subpedunculated) were excised by the standard inject-and-cut method, with standard accessories. The median size of all lesions was 10 mm (range 2-50 mm) and 110 (49.2%) lesions were located in the proximal colon. Histological completeness of resection was achieved in 87% of cases. Of the lesions 77.2% were dysplastic, with 5 cases of carcinoma in situ and 18 severely dysplastic adenomas. Complications included bleeding in five cases (2.2 %) and a single case of perforation (0.4%). All complications were managed endoscopically. Median follow up at 24 +/- 16 months (range 12-84 months) revealed a 7.2% local recurrence rate, all of which were subsequently eradicated by repeat EMR.

    CONCLUSIONS: Standard inject-and-cut colonic EMR is practical and effective in the eradication of superficial colonic neoplasia.

    Hemangiopericytoma is a very rare angiogenic tumor. In the nasal cavity, it can be considered malignant. It occurs in various parts of the body but those in the nasal cavity account for only 5% of total cases. Less than 200 cases have been reported worldwide involving the nose and paranasal sinuses. Due to its rarity a proper line of management has not been established to tackle this tumour. This article highlights two cases of hemangiopericytoma (HPC), one in an adult and the other in a child, presenting as an intranasal mass.

    Exophytic lesions involving the face present with an undesirable esthetic deformity and usually necessitate surgical excision. Conventional open excision techniques may lead to scar formation or pigmentation issues postoperatively. Minimally invasive endoscope-assisted surgery will be able to overcome these problems. However, this technique is not widely used because of the limited optical cavity working space, which hinders good visualization. We describe a technique to improve the optical cavity workspace to enable adequate endoscope-assisted surgical excision of forehead lesions in 2 cases. Foley's catheter and ribbon gauze were used in both cases to gain optical cavity workspace. The surgical technique is described in detail. One case had a frontal osteoma, whereas other was a nodular fasciitis of the forehead, confirmed by histology. Postoperative follow-up showed good outcomes at 1 year with no recurrences. Both patients were satisfied with the surgical and cosmetic outcomes. Endoscopic excision of a forehead lesion using the described technique is both safe and reliable. It is an excellent method for excising benign growths over the forehead while being cosmetically acceptable.

    OBJECTIVE: A global consensus meeting was held to review current evidence and knowledge gaps and propose collaborative studies on population-wide screening and eradication of Helicobacter pylori for prevention of gastric cancer (GC).

    METHODS: 28 experts from 11 countries reviewed the evidence and modified the statements using the Delphi method, with consensus level predefined as ≥80% of agreement on each statement. The Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach was followed.

    RESULTS: Consensus was reached in 26 statements. At an individual level, eradication of H. pylori reduces the risk of GC in asymptomatic subjects and is recommended unless there are competing considerations. In cohorts of vulnerable subjects (eg, first-degree relatives of patients with GC), a screen-and-treat strategy is also beneficial. H. pylori eradication in patients with early GC after curative endoscopic resection reduces the risk of metachronous cancer and calls for a re-examination on the hypothesis of 'the point of no return'. At the general population level, the strategy of screen-and-treat for H. pylori infection is most cost-effective in young adults in regions with a high incidence of GC and is recommended preferably before the development of atrophic gastritis and intestinal metaplasia. However, such a strategy may still be effective in people aged over 50, and may be integrated or included into national healthcare priorities, such as colorectal cancer screening programmes, to optimise the resources. Reliable locally effective regimens based on the principles of antibiotic stewardship are recommended. Subjects at higher risk of GC, such as those with advanced gastric atrophy or intestinal metaplasia, should receive surveillance endoscopy after eradication of H. pylori.

    CONCLUSION: Evidence supports the proposal that eradication therapy should be offered to all individuals infected with H. pylori. Vulnerable subjects should be tested, and treated if the test is positive. Mass screening and eradication of H. pylori should be considered in populations at higher risk of GC.

    Bacterial infections are common in cirrhotic patients with acute variceal bleeding, occurring in 20% within 48 h. Outcomes including early rebleeding and failure to control bleeding are strongly associated with bacterial infection. However, mortality from variceal bleeding is largely determined by the severity of liver disease. Besides a higher Child-Pugh score, patients with hepatocellular carcinoma are particularly susceptible to infections. Despite several hypotheses that include increased use of instruments, greater risk of aspiration pneumonia and higher bacterial translocation, it remains debatable whether variceal bleeding results in infection or vice versa but studies suggest that antibiotic prophylaxis prior to endoscopy and up to 8 h is useful in reducing bacteremia and spontaneous bacterial peritonitis. Aerobic gram negative bacilli of enteric origin are most commonly isolated from cultures, but more recently, gram positives and quinolone-resistant organisms are increasingly seen, even though their clinical significance is unclear. Fluoroquinolones (including ciprofloxacin and norfloxacin) used for short term (7 d) have the most robust evidence and are recommended in most expert guidelines. Short term intravenous cephalosporin (especially ceftriaxone), given in a hospital setting with prevalent quinolone-resistant organisms, has been shown in studies to be beneficial, particularly in high risk patients with advanced cirrhosis.

    Surgical robots have been appearing in operating rooms over the past decade, and neurosurgery has been one of the pioneers in this area. In neurosurgery, the clinical use of robots has been limited to stereotactic procedures and endoscopic manoeuvres, although the brain is a unique organ and well-suited for robotic application. The aim of this study was to assess the ability of our vision-guided robotic system to perform basic neurosurgical procedures.

    Mucoepidermoid carcinoma (MEC) is a rare tumour of the trachea accounting for up to 0.2% of reported primary lung malignancy. We report a case of a 54-year-old man, ex-smoker, whose presentation mimicked adult onset asthma with cough and wheezing, which did not respond to conventional treatment. He had occasional haemoptysis and weight loss in which CT scan performed for malignancy screening showed a protruding mass in the distal trachea causing endobronchial obstruction. Bronchoscopic intervention was performed to relieve the obstruction that resulted in resolution of asthmatic symptoms. Histological diagnosis confirmed MEC. This case emphasised the importance of a high index of suspicion in an unusual presentation of a common disease and the pivotal role of bronchoscopic intervention in malignant central airway obstruction.

    A total of 36 patients with suspected foreign body (FB) of the oesophagus who underwent rigid endoscopy under general anaesthesia (GA) from January 2005 to March 2007 were reviewed. The majority of the patients were working adults in the 3rd to 5th decade of life. There was no foreign body in 33.3% of the patients. Co-morbidities were present in 33.3%. Morbidity and mortality from the procedure included one aspiration pneumonia, one lateral pharyngeal wall tear and one death (8.3%). X-ray findings were negative or inconclusive in 11(45.8%) patients with a foreign body. The majority of patients, 85.7% required 2 to 3 days of admission of which 52.7% had no foreign bodies. The most common foreign body retrieved was fishbone accounting for 13 of the 24 foreign bodies detected.

    BACKGROUND A rectal foreign body (RFB) can be stigmatizing for patients and present a dilemma for the treating physician. Removal can be challenging owing to the variety of objects introduced. The goals of therapy are to safely remove the RFB and to minimize injury to the bowel. CASE REPORT A 22-year-old man was referred from a district hospital to our institution after being unable to remove a self-inflicted RFB after sexual gratification. He was hemodynamically stable with a soft and nontender abdomen. A mass was felt in the suprapubic region. Abdominal radiography revealed a well-defined radiolucent object in the pelvic region, which was consistent with a lubricant bottle. No sign of bowel obstruction or perforation was observed. The RFB was successfully retrieved by a combination of transrectal digital manipulation and directed gentle abdominal pressure, allowing for descent of the RFB and transanal traction at the bedside. Various approaches have been described for removal of a RFB, from simple bedside strategies to open surgery for complicated cases. Endoscopy and minimally invasive techniques have also demonstrated a role in formulating a tailored approach. CONCLUSIONS We describe a successful retrieval of an RFB at the bedside, avoiding unnecessary open surgery.

    The COVID-19 pandemic has had a profound impact on provision of endoscopy services globally as staff and real estate were repurposed. As we begin to recover from the pandemic, a cohesive international approach is needed, and guidance on how to resume endoscopy services safely to avoid unintended harm from diagnostic delays. The aim of these guidelines is to provide consensus recommendations that clinicians can use to facilitate the swift and safe resumption of endoscopy services. An evidence-based literature review was carried out on the various strategies used globally to manage endoscopy during the COVID-19 pandemic and control infection. A modified Delphi process involving international endoscopy experts was used to agree on the consensus statements. A threshold of 80% agreement was used to establish consensus for each statement. 27 of 30 statements achieved consensus after two rounds of voting by 34 experts. The statements were categorised as pre-endoscopy, during endoscopy and postendoscopy addressing relevant areas of practice, such as screening, personal protective equipment, appropriate environments for endoscopy and infection control precautions, particularly in areas of high disease prevalence. Recommendations for testing of patients and for healthcare workers, appropriate locations of donning and doffing areas and social distancing measures before endoscopy are unique and not dealt with by any other guidelines. This international consensus using a modified Delphi method to produce a series of best practice recommendations to aid the safe resumption of endoscopy services globally in the era of COVID-19.

    There is substantial progress in artificial intelligence (AI) algorithms and their medical sciences applications in the last two decades. AI-assisted programs have already been established for remotely health monitoring using sensors and smartphones. A variety of AI-based prediction models available for the gastrointestinal inflammatory, non-malignant diseases, and bowel bleeding using wireless capsule endoscopy, electronic medical records for hepatitis-associated fibrosis, pancreatic carcinoma using endoscopic ultrasounds. AI-based models may be of immense help for healthcare professionals in the identification, analysis, and decision support using endoscopic images to establish prognosis and risk assessment of patient's treatment using multiple factors. Although enough randomized clinical trials are warranted to establish the efficacy of AI-algorithms assisted and non-AI based treatments before approval of such techniques from medical regulatory authorities. In this article, available AI approaches and AI-based prediction models for detecting gastrointestinal, hepatic, and pancreatic diseases are reviewed. The limitation of AI techniques in such disease prognosis, risk assessment, and decision support are discussed.

    Many tests are available for the diagnosis of H. pylori infection. Broadly they can be divided into invasive- endoscopy biopsy based tests and non-invasive tests. Of the endoscopy biopsy based tests the rapid urease tests (RUT) have been found to be the most convenient, accurate and inexpensive tests and they have therefore been recommended by several consensus panels and working parties as the test of choice during endoscopy. Several RUTS are available; some are commercial: CLO test, Pyloritek, Helicobacter urease test, H. yylori test and others- "homemade". We strongly recommend the "homemade" 1 min rapid urease test using an unbuffered solution as originally described by Arvind et al. This test has been shown to be easy to prepare, inexpensive and accurate on field-testing. Several factors affect the accuracy of the RUT. The larger the size of biopsy samples, the quicker is the postive reaction time. With the CLO test, warming the tests to 37'C has also been shown to hasten the reaction time. The effect of blood on the RUT poses an important problem in testing. It is vitally important to determine the H. yylori status in patients with bleeding peptic ulcers as the recurrence of bleeding has been shown to be markedly reduced or virtually abolished with H. yylori eradication. While the results of studies have not been entirely consistent, it is likely that presence of blood does reduce the sensitivity of the RUT. It is therefore sensible that in patients with bleeding ulcers, the RUT should not be the sole endoscopy biopsy test used and that samples should also be taken for histological examination.

    The objective of this study was to determine the sensitivity, specificity, positive (PPV), and negative predictive values (NPV) of Diff-Quik-stained gastric imprint cytology smears in the detection of H. pylori compared with histology. Air-dried imprint smears of gastric biopsies from 150 patients were stained by the Diff-Quik method in the endoscopy suite and examined for H. pylori, providing results within minutes. The presence of inflammation and intestinal metaplasia were documented. The same biopsy was processed and stained with H&E and Warthin-Starry stains, and reviewed by a different pathologist blind to the imprint cytology results. Ninety-four of the 150 patients were male with a mean age of 50 years. Based on histology, the H. pylori prevalence was very low at 8%. The sensitivity and specificity of imprint cytology in the detection of H. pylori were 83.3% and 100%, respectively. The PPV and NPV were 100% and 98.6%, respectively. There were two false negatives and no false positives. A combination of imprint cytology and histology achieved 100% sensitivity. Imprint smears did not provide added value over histology with regards to inflammation and metaplasia. Gastric imprint smears stained with Diff-Quik method is a rapid, cheap, and reliable method for the detection of H. pylori and have their best results when complemented with histology.

    OBJECTIVE: To assess the quality of life (QoL) and recurrence of disease in patients with eosinophilic (ECRSwNP) and non-eosinophilic chronic rhinosinusitis with nasal polyposis (non-ECRSwNP) post endoscopic sinus surgery (ESS).

    METHODOLOGY: A cross-sectional comparative study was carried out in the Otorhinolaryngology - HNS Department, Universiti Kebangsaan Malaysia Medical Center (UKMMC). Subjective assessments of nasal symptoms and quality of life (QoL) using SNOT-22 and Visual Analogue Scale (VAS) and objective endoscopic assessment was undertaken using a modified Hadley endoscopic examination.

    RESULTS: There was no significant statistical difference in the quality of life between the ECRSwNP and non-ECRSwNP groups as evidenced by the SNOT-22 score and the VAS comparison (p>0.05). However, there was a significant difference in terms of recurrence of disease with the presence of nasal polyps on endoscopic examination. (p = 0.016) CONCLUSION: In conclusion, we found that there is no significant difference in QoL between ECRSwNP and non- ECRSwNP. There is higher frequency of recurrence of nasal polyps amongst ECRSwNP.

    BACKGROUND: Pyoderma gangrenosum (PG) is an uncommon, idiopathic, ulcerative neutrophilic dermatosis. In many cases, PG is associated with a wide variety of different disorders but SLE in association with PG is relatively uncommon. In this article we present the case of a middle aged patient with PG as the initial clinical presentation of SLE. We also provide a brief review of cobalamin deficiency which occurred in our patient and evidence-based management options.

    CASE PRESENTATION: A 35 years old man presented with a 5 month history of debilitating painful lower limb and scrotal ulcers. This was associated with polyarthralgia and morning stiffness involving both hands. He also complained of swallowing difficulties. He had unintentional weight loss of 10 kg and fatigue. Physical examination revealed alopecia, multiple cervical lymphadenopathies, bilateral parotid gland enlargement and atrophic glossitis. There was Raynaud's phenomenon noted over both hands and generalised hyper-pigmented fragile skin. Laboratory results disclosed anaemia, leukopenia, hyponatraemia and hypocortisolism. Detailed anaemic workup revealed low serum ferritin and cobalamin level. The autoimmune screen showed positive ANA, anti SmD1, anti SS-A/Ro 52, anti SSA/Ro 60, anti U1-snRNP with low complement levels. Upper gastrointestinal endoscopy with biopsies confirmed atrophic gastritis and duodenitis. Intrinsic factor antibodies and anti-tissue transglutaminase IgA were all negative. Punch biopsies of the leg ulcer showed neutrophilic dermatosis consistent with pyoderma gangrenosum. Based on the clinical findings and positive immunologic studies, he was diagnosed as systemic lupus erythematosus. His general condition improved substantially with commencement of corticosteroids, immunosuppressants and vitamin supplements.

    CONCLUSIONS: We report a case of PG as the first manifestation of SLE which was treated successfully with immunosuppressants and vitamin supplements. Our report highlighted the need to consider connective tissue diseases such as SLE in a patient presenting with PG in order for appropriate treatment to be instituted thereby achieving a good outcome.
