[DOI: 10.12998/wjcc.v12.i27.6105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 06/21/2024] [Accepted: 07/10/2024] [Indexed: 07/29/2024] Open
Abstract
BACKGROUND The coexistence of esophageal variceal bleeding and superficial esophageal cancer (SEC) is relatively rare in clinical practice. Moreover, there have been few reports of SEC overlying esophageal varices (EVs). Herein, we report our successful use of endoscopic submucosal dissection (ESD), esophageal solitary venous dilatation (ESVD), and endoscopic injection sclerotherapy (EIS) to treat a 75-year-old man who was diagnosed with SEC coexisting with esophageal variceal bleeding.
CASE SUMMARY A 75-year-old man was admitted to the hospital due to black stool for 4 days. The patient had a history of liver cancer, cirrhosis, and portal hypertension. Endoscopic examination revealed esophageal and gastric varicose veins, as well as esophageal carcinoma in situ. We first treated esophageal variceal bleeding by ESVD and EIS. One week later, ESD treatment was done, and the complete resection of early esophageal cancer was successfully completed via endoscopy. There were no postoperative complications, such as bleeding, infection, or perforation.
CONCLUSION The sequential treatment of ESVD, EIS, and ESD is an effective method for treating EVs with early esophageal cancer.

Quantitative Magnetic Resonance Cholangiopancreatography Scoring and Its Predictive Value for Outcomes in Adults with Primary Sclerosing Cholangitis. J Clin Med 2024; 13:4548. [PMID: 39124814 PMCID: PMC11312640 DOI: 10.3390/jcm13154548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2024] [Revised: 07/13/2024] [Accepted: 08/01/2024] [Indexed: 08/12/2024] Open
Abstract
Background: Primary sclerosing cholangitis (PSC) is an immune-mediated disease that has an unfavorable prognosis and needs a liver transplant (LT). The aim of this paper was to show the usefulness of the Majoie classification on magnetic resonance cholangiopancreatography (MRCP) images in assessing the prognosis in adult patients with PSC. Methods: Our work presents a retrospective monocentric study performed on 64 adult patients with PSC of the large bile ducts. Two radiologists evaluated the MRCP of diagnosis and calculated MRCP scores using the Majoie classification. Liver-related outcome (LT or liver-related death) was marked as a primary endpoint. Results: Univariate analysis showed that patients with more severe lesions (sum score of intrahepatic and extrahepatic ducts > 3) had a lower age at diagnosis, of 37.2 years, complicated with liver cirrhosis (53.1% of patients) and recurrent cholangitis (28.1%) p < 0.05, without significant differences in mortality, association with IBD or LT. Concordance analysis between MRCP prognostic scores and progression to a PSC-related event showed a moderate relationship (c-statistic 0.662), and a good AUROC was observed for the UKPSC score (0.893) and the MRS (0.936). Conclusions: In the study, we observed a good correlation between the imaging scores based on the Majoie classification and the evolution of the patients. These scores were outperformed by the UKPSC, MRS, and PREsTo clinical models. Their utility was best in predicting recurrent cholangitis.

Abstract
The various forms of Percutaneous Endoscopic Gastrostomy (PEG) are highly relevant in neurology, as pump-administered intrajejunal levodopa application is one of the indispensable forms of therapy in advanced Parkinson's disease. Optimal PEG placement and follow-up are therefore significant for the success of the therapy. However, the standard intrajejunal administration of levodopa gel via a JET-PEG, i. e. a PEG with an internal catheter inserted into the jejunum, is not without problems for various reasons. In particular, the considerable cumulative complication rates demand a reconsideration of the situation. The very limited absorption area of the drug in the region of the flexura duodenojejunalis must also be taken into account. Causes of complications are predominantly a non-optimal application technique of PEG and internal catheter as well as the frequent lack of an adequate follow-up. In this paper, the details of a modified and optimized application technique compared to the conventional techniques are presented. These new methods have proved their usefulness in clinical applications for years, and additionally a new application form, the Hybrid-PEG, is presented. However, many of the details derived from anatomical/physiological, surgical and endoscopic aspects must be strictly observed during the application in order to reduce or avoid minor and major complications. In particular, problems are caused by local infections in the area of the insertion point of the PEG including peritonitis, leaks and buried bumper syndrome (BBS). The relatively frequent dislocations of the internal catheter also prove to be particularly troublesome. These can ultimately be avoided by clip fixation of the catheter tip down in the jejunum. In particular, the use of the newly developed Hybrid-PEG, a combination of endoscopically controlled gastropexy with three sutures and subsequent central thread-pull-through of the PEG tube, can significantly reduce the complication rate and thus achieve a decisive improvement for patients. The aspects discussed here are highly relevant for all those involved in the therapy of advanced Parkinson's disease. Trustful interdisciplinary collaboration between neurology and endoscopy/surgery/gastroenterology is a prerequisite for good clinical outcomes.

Abstract
INTRODUCTION Primary sclerosing cholangitis (PSC) is a bile duct disorder characterized by ductular reaction, hepatic inflammation, and liver fibrosis. The pathogenesis of PSC is still undefined, and treatment options for patients are limited. Previous clinical trials evaluated drug candidates targeting various cellular functions and pathways, such as bile acid signaling and absorption, gut bacteria and permeability, and lipid metabolisms. However, most of phase III clinical trials for PSC were disappointing, except vancomycin therapy, and there are still no established medications for PSC with efficacy and safety confirmed by phase IV clinical trials. AREAS COVERED This review summarizes the currently ongoing or completed clinical studies for PSC, which are phase II or further, and discusses therapeutic targets and strategies, limitations, and future directions and possibilities of PSC treatments. A literature search was conducted in PubMed and ClinicalTrials.gov utilizing the combination of the searched term 'primary sclerosing cholangitis' with other keywords, such as 'clinical trials,' 'antibiotics,' or drug names. Clinical trials at phase II or further were included for consideration. EXPERT OPINION Only vancomycin demonstrated promising therapeutic effects in the phase III clinical trial. Other drug candidates showed futility or inconsistent results, and the search for novel PSC treatments is still ongoing.

Abstract
In the 21st century, the development of medical science has entered the era of big data, and machine learning has become an essential tool for mining medical big data. The establishment of the SEER database has provided a wealth of epidemiological data for cancer clinical research, and the number of studies based on SEER and machine learning has been growing in recent years. This article reviews recent research based on SEER and machine learning and finds that the current focus of such studies is primarily on the development and validation of models using machine learning algorithms, with the main directions being lymph node metastasis prediction, distant metastasis prediction, and prognosis-related research. Compared to traditional models, machine learning algorithms have the advantage of stronger adaptability, but also suffer from disadvantages such as overfitting and poor interpretability, which need to be weighed in practical applications. At present, machine learning algorithms, as the foundation of artificial intelligence, have just begun to emerge in the field of cancer clinical research. The future development of oncology will enter a more precise era of cancer research, characterized by larger data, higher dimensions, and more frequent information exchange. Machine learning is bound to shine brightly in this field.

Abstract
Spinal endoscopy has evolved significantly since its inception, offering minimally invasive solutions for various spinal pathologies. This study introduces a promising innovation in spinal endoscopy-a single-use digital endoscope designed to overcome the drawbacks of traditional optic endoscopes. Traditional endoscopes, despite their utility, present challenges such as fragility, complex disinfection processes, weight issues, and susceptibility to mechanical malfunctions. The digital endoscope, with its disposable nature, lighter weight, and improved image quality, aims to enhance surgical procedures and patient safety. The digital endoscope system comprises a 30-degree 1000 × 1000 pixel resolution camera sensor with a 4.3 mm working channel, and LED light sources replacing optical fibers. The all-in-one touch screen tablet serves as the host computer, providing portability and simplified operation. Image comparisons between the digital and optic endoscopes revealed advantages in the form of increased field of view, lesser distortion, greater close-range resolution, and enhanced luminance. The single-use digital endoscope demonstrates great potential for revolutionizing spine endoscopic surgeries, offering convenience, safety, and superior imaging capabilities compared to traditional optic endoscopes.

Abstract
Gastrointestinal (GI) endoscopy is among the highest waste generator in healthcare facilities. The major reasons include production of large-volume non-renewable waste, use of single-use devices, and reprocessing or decontamination processes. Single-use endoscopic accessories have gradually replaced reusable devices over last two decades contributing to the rising impact of GI endoscopy on ecosystem. Several reports of infection outbreaks with reusable duodenoscopes raised concerns regarding the efficacy and adherence to standard disinfection protocols. Even the enhanced reprocessing techniques like double high-level disinfection have not been found to be the perfect ways for decontamination of duodenoscopes and therefore, paved the way for the development of single-use duodenoscopes. However, the use of single-use endoscopes is likely to amplify the net waste generated and carbon footprint of any endoscopy unit. Moreover, single-use devices challenge one of the major pillars of sustainability, that is, "reuse." In the era of climate change, a balanced approach is required taking into consideration patient safety as well as financial and environmental implications. The possible solutions to provide optimum care while addressing the impact on climate include selective use of disposable duodenoscopes and careful selection of accessories during a case. Other options include use of disposable endcaps and development of effective high-level disinfection techniques. The collaboration between the healthcare professionals and the manufacturers is paramount for the development of environmental friendly devices with low carbon footprint.

Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide and responsible for approximately 1 million deaths annually. Early screening is essential to increase the chances of survival, and it can also reduce the cost of treatments for healthcare centres. Colonoscopy is the gold standard for CRC screening and treatment, but it has several drawbacks, including difficulty in manoeuvring the device, patient discomfort, and high cost. Soft endorobots, small and compliant devices thatcan reduce the force exerted on the colonic wall, offer a potential solution to these issues. However, controlling these soft robots is challenging due to their deformable materials and the limitations of mathematical models. In this Review, we discuss model-free and model-based approaches for controlling soft robots that can potentially be applied to endorobots for colonoscopy. We highlight the importance of selecting appropriate control methods based on various parameters, such as sensor and actuator solutions. This review aims to contribute to the development of smart control strategies for soft endorobots that can enhance the effectiveness and safety of robotics in colonoscopy. These strategies can be defined based on the available information about the robot and surrounding environment, control demands, mechanical design impact and characterization data based on calibration.

Pump-guided intrajejunal levodopa administration is one of the indispensable forms of therapy in advanced Parkinson's syndrome, along with deep brain stimulation and subcutaneous apomorphine injection. The standard application of levodopa gel via a JET-PEG, i.e. a percutaneous endoscopic gastrostomy (PEG) with an inserted internal catheter into the jejunum, has not been unproblematic due to the restricted absorption area of the drug in the region of the flexura duodenojejunalis and especially due to the sometimes considerable accumulated complication rates of a JET-PEG. Causes of complications are mainly a non-optimal application technique of PEG and internal catheter as well as the often missing adequate follow-up care.

However, many details derived from anatomical, physiological, surgical and endoscopic aspects must be strictly observed during the application to reduce or avoid minor and major complications. Local infections and buried bumper syndrome cause particular problems. The relatively frequent dislocations of the internal catheter (which can ultimately be avoided by clip-fixing the catheter tip) also prove to be particularly troublesome. Finally, using the Hybrid technique, a new combination of an endoscopically controlled gastropexy with 3 sutures and subsequent central thread pull-through (TPT) of the PEG tube, the complication rate can be dramatically reduced and thus a decisive improvement achieved for patients. The aspects discussed here are highly relevant for all those involved in the therapy of advanced Parkinson's syndrome.

Abstract
BACKGROUND Esophageal cancer has high incidence globally and is often diagnosed at an advanced stage. With the widespread application of endoscopic technologies, the need for early detection and diagnosis of esophageal cancer has gradually been realized. Endoscopic submucosal dissection (ESD) has become the standard of care for managing early tumors of the esophagus, stomach, and colon. However, due to the steep learning curve, difficult operation, and technically demanding nature of the procedure, ESD has currently been committed to the development of various assistive technologies. AIM To explore the feasibility and applicability of magnetic anchor technique (MAT)-assisted ESD for early esophageal cancer. METHODS Isolated pig esophagi were used as the experimental model, and the magnetic anchor device was designed by us. The esophagi used were divided into two groups, namely the operational and control groups, and 10 endoscopists completed the procedure. The two groups were evaluated for the following aspects: The total operative time, perforation rate, rate of whole mucosal resection, diameter of the peering mucosa, and scores of endoscopists' feelings with the procedure, including the convenience, mucosal surface exposure degree, and tissue tension. In addition, in the operational group, the soft tissue clip and the target magnet (TM) were connected by a thin wire through a small hole at the tail end of the TM. Under gastroscopic guidance, the soft tissue clip was clamped to the edge of the lesioned mucosa, which was marked in advance. By changing the position of the anchor magnet (AM) outside the esophagus, the pulling force and pulling direction of the TM could be changed, thus exposing the mucosal peeling surface and assisting the ESD. RESULTS Herein, each of the two groups comprised 10 isolated esophageal putative mucosal lesions. The diameter of the peering mucosa did not significantly differ between the two groups (2.13 ± 0.06 vs 2.15 ± 0.06, P = 0.882). The total operative time was shorter in the operational group than in the control group (17.04 ± 0.22 min vs 21.94 ± 0.23 min, P < 0.001). During the entire experiment, the TM remained firmly connected with the soft tissue clip and did not affect the opening, closing, and release of the soft tissue clip. The interaction between the TM and AM could provide sufficient tissue tension and completely expose the mucosa, which greatly assists the surgeon with the operation. There was no avulsion of the mucosa, and mucosal lesions were intact when peeled. Therefore, the scores of endoscopists' feelings were higher in the operational group than in the control group in terms of the convenience (9.22 ± 0.19 vs 8.34 ± 0.15, P = 0.002), mucosal surface exposure degree (9.11 ± 0.15 vs 8.25 ± 0.12, P < 0.001), and tissue tension (9.35 ± 0.13 vs 8.02 ± 0.17, P < 0.001). The two groups did not significantly differ in the perforation rate and rate of whole mucosal resection. CONCLUSION We found MAT-assisted ESD safe and feasible for early esophageal cancer. It could greatly improve the endoscopic operation experience and showed good clinical application prospects.

Abstract
BACKGROUND Greenhouse gases (GHGs) are significant contributors to climate change, and CO2 equivalent (CO2-e) is measured to compare emissions from GHGs. The healthcare sector contributes 4.4% of global CO2-e emissions, mainly with energy consumption and, in lesser extent, waste production. In this regard, bronchoscopy procedures produce a large amount of waste and are responsible for a significant consumption of energy. OBJECTIVE We aimed at quantifying the impact on waste mass production, energy consumption, and recyclability of bronchoscopic procedures. METHODS We conducted a prospective single-centre observational study; for each type of procedure (performed with either reusable or single-use instruments), the number of items used, their weight, and recyclability were evaluated, as well as the material of which recyclable waste was made of. We then calculated the total amount of waste produced, its recyclability, energy consumption, and CO2-e produced over 10 days of activity in our Interventional Pulmonology Unit. RESULTS Sixty procedures generated 61,928 g of waste, of which only 15.8% was potentially recyclable. Single-use instruments generated nearly twofold more recyclable waste than reusable ones, 80% during the procedure phase. Reusable instruments generated 45% of waste during the reprocessing phase, of which 50% was recyclable. The recyclable material was totally composed of paper and plastic. During 10 days of activity, we consumed 64 kWh and produced more than 67 kg of CO2-e due to non-recyclable waste and energy consumption. CONCLUSIONS Our results confirm the compelling need to recycle as many materials as possible, even if the amount of recyclable waste is limited. In this respect, official documents issued by international societies are urgently needed to align our activity with climate requirements and improve the sustainability of our work.

Abstract
This document from the American Society for Gastrointestinal Endoscopy (ASGE) provides a full description of the methodology used in the review of the evidence used to inform the final guidance outlined in the accompanying Summary and Recommendations document regarding the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. This guideline used the Grading of Recommendations, Assessment, Development and Evaluation framework and specifically addresses the role of ESD versus EMR and/or surgery, where applicable, for the management of early esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric adenocarcinoma (GAC) and their corresponding precursor lesions. For ESCC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer >15 mm, whereas in patients with similar lesions ≤15 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for such patients with ESCC, whenever possible. For EAC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer >20 mm, whereas in patients with similar lesions measuring ≤20 mm, the ASGE suggests either ESD or EMR. For GAC, the ASGE suggests ESD over EMR for patients with early-stage, well or moderately differentiated, nonulcerated intestinal type cancer measuring 20 to 30 mm, whereas for patients with similar lesions <20 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for patients with such lesions measuring ≤30 mm, whereas for lesions that are poorly differentiated, regardless of size, the ASGE suggests surgical evaluation over endosic approaches.

Abstract
BACKGROUND Liver cirrhosis and esophageal cancer share several risk factors, such as alcohol intake and excess weight. Endoscopic resection is the gold standard treatment for superficial tumors. Portal hypertension and coagulopathy may increase the bleeding risk in these patients. This study aimed to assess the safety and efficacy of endoscopic resection for early esophageal neoplasia in patients with cirrhosis or portal hypertension. METHODS This retrospective multicenter international study included consecutive patients with cirrhosis or portal hypertension who underwent endoscopic resection in the esophagus from January 2005 to March 2021. RESULTS 134 lesions in 112 patients were treated, including by endoscopic submucosal dissection in 101 cases (75 %). Most lesions (128/134, 96 %) were in patients with liver cirrhosis, with esophageal varices in 71 procedures. To prevent bleeding, 7 patients received a transjugular intrahepatic portosystemic shunt, 8 underwent endoscopic band ligation (EBL) before resection, 15 received vasoactive drugs, 8 received platelet transfusion, and 9 underwent EBL during the resection procedure. Rates of complete macroscopic resection, en bloc resection, and curative resection were 92 %, 86 %, and 63 %, respectively. Adverse events included 3 perforations, 8 delayed bleedings, 8 sepsis, 6 cirrhosis decompensations within 30 days, and 22 esophageal strictures; none required surgery. In univariate analysis, cap-assisted endoscopic mucosal resection was associated with delayed bleeding (P = 0.01). CONCLUSIONS In patients with liver cirrhosis or portal hypertension, endoscopic resection of early esophageal neoplasia appeared to be effective and should be considered in expert centers with choice of resection technique, following European Society of Gastrointestinal Endoscopy guidelines to avoid undertreatment.

Abstract
Early diagnosis and treatment of diseases in the gastrointestinal (GI) tract including colorectal cancers (CRC) via natural orifices have led to a significant increase in patient survival rates. Most screening procedures utilize image-guided techniques via a conventional endoscope. The cost of conventional endoscopes is substantial, ranging in the tens of thousands of USD or more. This presents significant burden for developing countries, which are disproportionally affected by gastroenterological diseases. Conventional endoscopes also require sterilization between use. This increases the chance of cross-infection between patients. To address these problems, this paper introduces a soft endoscope with a disposable insertion tube that can be articulated. This prototype device is hydraulically actuated, capable of a 10 mm bend radius and 180-degree bend angle. The camera system provides 110 degrees field-of-view. The component parts of this disposable endoscope costs less than 200 USD.Clinical relevance-Our low-cost, single-use endoscope eliminates the sterilization step required by conventional systems, thereby reducing the risks of infection and lowering the operating costs. There is also significant scope for our device to be used beyond the human GI track, such as screening for lung or bladder cancers. Given the compact footprint, the minimal cost of the disposable parts, the proposed platform can widen cancer screening programs with quantifiable economic benefit for many patients, particularly those in developing countries.

Abstract
Objective: Quantitatively compare the ergonomics of traditional tonsillectomy versus an endoscopic-assisted tonsillectomy. Methods: The physical positioning of the senior author was studied during a simulation of two different operative approaches to tonsillectomy: one using an endoscope and one using direct visualization without the aid of an endoscope. Whole-body postural data was collected and analyzed using the validated Rapid Upper Limb Assessments (RULA) tool to calculate the risk of musculoskeletal injuries. Results: Severe neck and trunk flexion are high-risk postures unique to the traditional approach. The RULA score for the traditional, non-endoscopic approach was 5, with a Neck, Trunk, and Leg Score of 6 and a Wrist/Arm score of 1. The RULA score for the endoscopic-assisted approach was 3, with a Neck, Trunk, and Leg score of 4 and a Wrist/Arm score of 1. The difference between the two approaches narrowed down to the effect on neck positioning (angle decreased from > 20 degrees with traditional to nearly 0 degrees with endoscopic) and trunk positioning (angle decreased from 20 to 60 degrees with traditional to 0 degrees with endoscopic). Conclusion: An endoscopic-assisted approach to tonsillectomy allowed for a lower RULA score compared to the traditional tonsillectomy. This study suggests that an endoscopic approach may decrease the potential for musculoskeletal strain and reduce occupational-related pain and injury seen in practicing otolaryngologists.

Abstract
BACKGROUND Lugol chromoendoscopy (LCE) has served as a standard screening technique in high-risk patients with esophageal cancer. Nevertheless, LCE is not suitable for general population screening given its side effects. Linked color imaging (LCI) is a novel image-enhanced endoscopic technique that can distinguish subtle diff-erences in mucosal color.
AIM To compare the diagnostic performance of LCI with LCE in detecting esophageal squamous cell cancer and precancerous lesions and to evaluate whether LCE can be replaced by LCI in detecting esophageal neoplastic lesions.
METHODS In this prospective study, we enrolled 543 patients who underwent white light imaging (WLI), LCI and LCE successively. We compared the sensitivity and specificity of LCI and LCE in the detection of esophageal neoplastic lesions. Clinicopathological features and color analysis of lesions were assessed.
RESULTS In total, 43 patients (45 neoplastic lesions) were analyzed. Among them, 36 patients (38 neoplastic lesions) were diagnosed with LCI, and 39 patients (41 neoplastic lesions) were diagnosed with LCE. The sensitivity of LCI was similar to that of LCE (83.7% vs 90.7%, P = 0.520), whereas the specificity of LCI was greater than that of LCE (92.4% vs 87.0%, P = 0.007). The LCI procedure time in the esophageal examination was significantly shorter than that of LCE [42 (34, 50) s vs 160 (130, 189) s, P < 0.001]. The color difference between the lesion and surrounding mucosa in LCI was significantly greater than that observed with WLI. However, the color difference in LCI was similar in different pathological types of esophageal squamous cell cancer.
CONCLUSION LCI offers greater specificity than LCE in the detection of esophageal squamous cell cancer and precancerous lesions, and LCI represents a promising screening strategy for general populations.

Abstract
Abstract
Background Screening for gastric cancer is known to be associated with reduced mortality in populations with high prevalence. However, many countries with high prevalence do not screen, with high costs being a significant reason for this.
Aims To describe, develop, and assess the potential for a low-cost gastroscope for early cancer screening and patient risk stratification.
Methods Our interdisciplinary team used both off-the-shelf and fabricated components to create multiple gastroscope prototypes (GP) in iterative fashion based off clinician feedback. Clinician endoscopists were surveyed using Likert scales regarding device potential, video quality, and handling when testing on a GI training device. Video quality comparison to clinically standard high-definition white light endoscopy (HD-WLE) was done using the absolute categorical ratings (ACR) method.
Results A candidate cost-effective GP with clinical potential was developed. Although initial versions were scored as inferior via ACR on all views tested when compared to HD-WLE (p < 0.001), participants agreed the concept may be beneficial (M = 4.52/5, SD = 0.72). In testing improved versions, participants agreed the device had the ability to identify discrete (M = 4.62/5, SD = 0.51) and subtle lesions (M = 4/5, SD = 0.7) but most felt video quality, although improved, was still less than HD-WLE. Sufficiency of maneuverability of device to visualize gastric views was rated as equivocal (M = 2.69/5, SD = 1.25). Conclusion The presented low-cost gastroscopic devices have potential for clinical application. With further device development and refinement including the possible addition of technologies in telemedicine and artificial intelligence, we hope the GP can help expand gastric cancer screening for populations in need.

[PMID: 37035346 PMCID: PMC10078984 DOI: 10.3389/fmed.2023.1039979] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Accepted: 02/28/2023] [Indexed: 04/11/2023] Open
Abstract
Background Esophagogastroduodenoscopy (EGD) screening is vital for the early diagnosis of esophageal squamous cell cancer (ESCC). However, improvement in the detection rate of precancerous lesions and early ESCC with anesthesia assistance (AA) has not yet been investigated. This retrospective study aimed to evaluate the effect of AA on the detection rate of precancerous lesions and early ESCC in patients undergoing EGD screening and identify risk factors affecting the detection rate. Methods We reviewed patients' electronic medical records who underwent EGD screening between May 2019 and August 2020. Patients were divided into two groups based on whether they received AA: those in Group A underwent EGD screening with AA, and patients in Group O underwent EGD screening without AA. Propensity score matching (PSM) was used to account for differences in baseline characteristics. Detection rates of precancerous lesions and early ESCC were compared between the two groups following PSM. Binary logistic regression was used to identify risk factors affecting the detection rate. Results The final analysis included 21,835 patients (Group A = 13,319, Group O = 8,516) from 28,985 patients who underwent EGD screening during the study period. Following PSM, 6009 patients remained in each group for analysis. There was no significant difference in the detection rate of precancerous lesions and early ESCC between Groups A and O (1.1% vs. 0.8%, p > 0.05). Binary logistic regression showed that age (50-59 years, 60-69 years and 70-79 years), higher endoscopist seniority, high-definition (HD) endoscopy, narrow-band imaging (NBI), and number of endoscopic images were all independent risk factors that affected the detection rate of precancerous lesions and early ESCC. Conclusion There was no statistically significant difference in the detection rate of precancerous lesions and early ESCC between patients who underwent EGD screening with and without AA. All independent risk factors that affected the detection rate of precancerous lesions and early ESCC included the following: age (50-59 years, 60-69 years and 70-79 years), higher endoscopist seniority, HD endoscopy, NBI, and number of endoscopic images. Endoscopists should consider all these factors as much as possible when performing EGD screening.

Abstract
Esophageal squamous cell carcinoma (ESCC) is a common cancer in many developing countries in Asia and Africa, with a 5-year survival rate of approximately 20%. Most cases are diagnosed at an advanced age when there is no effective treatment strategy. Esophageal precancerous conditions have a much better prognosis, with a 5-year survival rate of over 90% by endoscopic diagnosis and treatment. Nevertheless, limitations, contraindications, and lymph node metastasis incompetency of endoscopy. Thus, the diagnosis and treatment of esophageal precancerous lesions remain a significant challenge. Biomarker investigations provide opportunities for target detection and therapy. Additionally, drug development is ongoing. Changes in lifestyle habits, such as diet balance, smoking and alcohol cessation, are beneficial for the prognosis of esophageal precancerous lesions. Collectively, multiple and sequential diagnoses and treatments are essential for curing esophageal precancerous lesions and reducing the incidence and mortality of ESCC.

Abstract
BACKGROUND Magnetically controlled capsule endoscopy (MCCE) has recently increasingly been used for gastric examination. However, the image quality and esophageal observation is suboptimal. We developed a novel wired transmission magnetically controlled capsule endoscopy (WT-MCCE) system and evaluated its feasibility through in vitro and in vivo experiments. METHODS A plastic stomach model and a pathological upper gastrointestinal model were used to evaluate the performance of WT-MCCE in vitro experiments. Twice of examination in the two in vitro models by WT-MCCE were performed by 5 endoscopists who were experienced in performing wireless capsule endoscopy. The examination of traditional gastroscopy (Olympus, GIF-HQ290) in the pathological upper gastrointestinal model was set as the control. In vivo experiments were performed in a live canine model by 3 endoscopists, in which WT-MCCE was inserted with the assistance of gastroscopy. Measurements included maneuverability, examination time, visualization of gastric mucosa, image quality and diagnostic accuracy. RESULTS WT-MCCE showed good performance in both in vitro and in vivo experiments with excellent visualization of mucosa (75-100%). The mean operation time is 17.6 ± 2.7 min, 22.3 ± 1.9 min and 29.3 ± 3.4 min in three models, respectively. In pathological upper gastrointestinal model, all lesions, including esophageal varices, one polyp, one foreign body, two gastric ulcers and one duodenal ulcer, were detected by both WT-MCCE and traditional gastroscopy by all endoscopists. For the observation of esophagus and stomach in the canine model, WT-MCCE also showed excellent maneuverability and good image quality. CONCLUSIONS The novel WT-MCCE system performed well in evaluating upper gastrointestinal landmarks and lesions in two in vitro models, and showed good performance in a canine model. WT-MCCE may be potentially useful for diagnosis of esophageal and gastric diseases.

Abstract
PURPOSE Given the association of inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC), we aimed to investigate the clinical relevance of abnormal hepatobiliary findings on magnetic resonance enterography (MRE) of IBD patients considering the risk of over- or underestimation of PSC at MRE. MATERIAL AND METHODS Using the MRE dataset of patients referring to a tertiary hospital and the National Registry of Crohn's and Colitis, 69 MREs, including 23 IBD-PSC, 23 IBD-without PSC, and 23 healthy controls (HC), were retrospectively reviewed by 2 experienced radiologists blinded to the clinical data, to evaluate hepatobiliary abnormalities. Sensitivity, specificity, and likelihood ratios were calculated. RESULTS Bile duct irregularities were the most common finding in the IBD-PSC group, with a frequency of 91%. Intra- and extrahepatic bile duct (IHBD and EHBD) irregularities were observed in 87% and 78% of PSC patients, respectively. Higher frequency of IHBD and EHBD wall thickening, bile duct dilation, EHBD stricture, and periportal oedema were observed in the IBD-PSC group. Peribiliary T2-weighted hyperintensities and contrast-enhancement were significantly more common in the IBD-PSC group than in the IBD and HC groups (48% and 35%, respectively) (p < 0.001). Detection of biliary irregularities on MRE had a specificity of 94% (95% CI: 82-99%), a sensitivity of 91% (95% CI: 72-99%), and a positive likelihood ratio of 14.0 (95% CI: 4.7-42.1) for the diagnosis of PSC. CONCLUSIONS This study emphasizes the importance of assessing and reporting hepatobiliary abnormalities visible in the MRE of patients with IBD to avoid a delayed diagnosis of PSC.

Abstract
Human papillomavirus (HPV) is thought to be sexually transmitted; however, there have been a few studies investigating a possible iatrogenic source of infection. Therefore, it is important to assess the cleaning methods of reusable medical devices. This study assessed whether cleaning methods of flexible endoscopes in an otolaryngology clinic are effective against HPV. There were 24 patients with a history of head and neck cancer in the study; however, two outliers were excluded. Nine patients were confirmed to have HPV-associated cancer. PCR was used to measure and quantify the viral genomes of samples collected before and after cleaning. After cleaning, few HPV+ samples had endoscopes with less DNA than before cleaning. Additionally, for several patients with non-HPV-associated head and neck cancer, PCR showed more DNA after cleaning than before cleaning, suggesting residual HPV DNA within the cleaning solution. There was no significant difference (p > 0.05) between pre- and post-cleaning in both cohorts. Current cleaning methods of reusable endoscopes may not be effective in completely removing viral DNA.

Abstract
Climate change and the destruction of ecosystems by human activities are among the greatest challenges of the 21st century and require urgent action. Health care activities significantly contribute to the emission of greenhouse gases and waste production, with gastrointestinal (GI) endoscopy being one of the largest contributors. This Position Statement aims to raise awareness of the ecological footprint of GI endoscopy and provides guidance to reduce its environmental impact. The European Society of Gastrointestinal Endoscopy (ESGE) and the European Society of Gastroenterology and Endoscopy Nurses and Associates (ESGENA) outline suggestions and recommendations for health care providers, patients, governments, and industry. MAIN STATEMENTS 1: GI endoscopy is a resource-intensive activity with a significant yet poorly assessed environmental impact. 2: ESGE-ESGENA recommend adopting immediate actions to reduce the environmental impact of GI endoscopy. 3: ESGE-ESGENA recommend adherence to guidelines and implementation of audit strategies on the appropriateness of GI endoscopy to avoid the environmental impact of unnecessary procedures. 4: ESGE-ESGENA recommend the embedding of reduce, reuse, and recycle programs in the GI endoscopy unit. 5: ESGE-ESGENA suggest that there is an urgent need to reassess and reduce the environmental and economic impact of single-use GI endoscopic devices. 6: ESGE-ESGENA suggest against routine use of single-use GI endoscopes. However, their use could be considered in highly selected patients on a case-by-case basis. 7: ESGE-ESGENA recommend inclusion of sustainability in the training curricula of GI endoscopy and as a quality domain. 8: ESGE-ESGENA recommend conducting high quality research to quantify and minimize the environmental impact of GI endoscopy. 9: ESGE-ESGENA recommend that GI endoscopy companies assess, disclose, and audit the environmental impact of their value chain. 10: ESGE-ESGENA recommend that GI endoscopy should become a net-zero greenhouse gas emissions practice by 2050.

Abstract
OBJECTIVE Procedure-intense specialties, such as surgery or endoscopy, are a major contributor to the impact of the healthcare sector on the environment. We aimed to measure the amount of waste generated during endoscopic procedures and to understand the impact on waste of changing from reusable to single use endoscopes in the USA. DESIGN We conducted a 5-day audit (cross-sectional study) of all endoscopies performed at two US academic medical centres with low and a high endoscopy volume (2000 and 13 000 procedures annually, respectively). We calculated the average disposable waste (excluding waste from reprocessing) generated during one endoscopic procedure to estimate waste of all endoscopic procedures generated in the USA annually (18 million). We further estimated the impact of changing from reusable to single-use endoscopes taking reprocessing waste into account. RESULTS 278 endoscopies were performed for 243 patients. Each endoscopy generated 2.1 kg of disposable waste (46 L volume). 64% of waste was going to the landfill, 28% represented biohazard waste and 9% was recycled. The estimated total waste generated during all endoscopic procedures performed in the USA annually would weigh 38 000 metric tons (equivalent of 25 000 passenger cars) and cover 117 soccer fields to 1 m depth. If all endoscopic procedures were performed with single-use endoscopes and accounting for reprocessing, the net waste mass would increase by 40%. Excluding waste from ancillary supplies, net waste generated from reprocessing and endoscope disposal would quadruple with only using single-use endoscopes. CONCLUSION This quantitative assessment of the environmental impact of endoscopic procedures highlights that a large amount of waste is generated from disposable instruments. Transitioning to single-use endoscopes may reduce reprocessing waste but would increase net waste.

Abstract
OBJECTIVES Salvage endoscopic resection is recommended when the local recurrence at primary site after chemoradiotherapy for esophageal squamous cell carcinoma is localized and superficial. This retrospective study aimed to comparatively analyse the short-term outcomes and local control of salvage endoscopic submucosal dissection versus salvage endoscopic mucosal resection for local recurrence after chemoradiotherapy or radiotherapy. METHODS A total of 96 patients who underwent initial salvage endoscopic resection for cT1N0M0 local recurrence after chemoradiotherapy or radiotherapy for esophageal squamous cell carcinoma between December 1998 and August 2019 patients were assigned to either the salvage endoscopic submucosal dissection (40 patients; 40 lesions) or salvage endoscopic mucosal resection (56 patients; 56 lesions) group. We evaluated the en bloc and R0 resection rates, severe adverse events and local failure rate after salvage endoscopic resection. Multivariate analysis was conducted to identify risk factors of local failure after salvage endoscopic resection. RESULTS The en bloc resection rate was significantly higher in the salvage endoscopic submucosal dissection group than in the salvage endoscopic mucosal resection group (95% versus 63%; P < 0.001). There were no differences in R0 resection rate between the two groups (73% versus 52%, P = 0.057). One patient (3%) in the salvage endoscopic submucosal dissection group had perforation. The 3-year cumulative local failure rate of salvage endoscopic mucosal resection was significantly higher than that of salvage endoscopic submucosal dissection (27% versus 5%, P = 0.032). In multivariate analysis, salvage endoscopic mucosal resection (hazard ratio: 2.7, P = 0.044) was the only independent risk factor of local failure after salvage endoscopic resection. CONCLUSIONS Salvage endoscopic submucosal dissection is the effective treatment for local recurrence based on the short-term outcomes and local efficacy.

This nationwide cohort study collected claims data from the Taiwanese Bureau of National Health Insurance from 2004 to 2013. The primary outcome, i.e., the risk of incident asthma, was assessed by estimating hazard ratios (HRs) and 95% confidence intervals (CIs). The adjusted HR of asthma development was estimated using the Cox regression model. Sensitivity and subgroup analyses were also conducted. A total of 8894 PPI users and 12,684 H2-receptor antagonist (H2RA) users were included in patients with CAD. Compared with H2RA use, an increased risk of incident asthma was found between PPI use and the risk of incident asthma in patients with CAD after adjusting for sex, age, urbanization, and low income (HR: 1.41; 95% CI: 1.04–1.89). The sensitivity analysis results were consistent with the main analysis results. However, the subgroup analysis revealed no association of incident asthma in patients with diabetes mellitus, hyperlipidemia, stroke, allergic rhinitis, pneumonia, cancer, or depression in the PPI group compared with those in the H2RA group. In conclusion, PPI use increased the risk of asthma development in patients with CAD.

New endoscopic capsule vs upper gastrointestinal endoscopy in preoperative work-up of obese candidate for bariatric surgery: Relevance of a pilot study in the COVID-19 era. Endosc Int Open 2022; 10:E183-E191. [PMID: 35178336 PMCID: PMC8847058 DOI: 10.1055/a-1723-3109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Accepted: 10/19/2021] [Indexed: 11/25/2022] Open
Abstract
Background and study aims Obesity represents a major health concern; bariatric surgery is the most effective treatment reducing and maintaining weight loss. The role of a routine esophagogastroduodenoscopy (EGD) prior bariatric surgery is still debated. Moreover, in this scenario of COVID-19 pandemic, EGD is even more questionable due to the procedural risk of viral transmission. A new model of video-endoscopic capsule (VEC) recently has been introduced as a good alternative to the EGD. The aim of this study was to determine if this new capsule is an adequate diagnostic alternative to EGD in the work-up of patients selected for bariatric surgery, particularly in the setting of COVID-19. Patients and methods From January to November 2020, 27 patients selected for bariatric surgery were enrolled in this pilot study to assess for noninferiority of VEC compared to EGD in detection of upper gastrointestinal disease. Results VEC had sensitivity, specificity, and positive and negative predictive values in identification of significant lesions of 91.3 %, 83.33 %, 98.01 %, and 51.57 %, respectively, compared with EGD as the standard criterion. The accuracy was 90.51 % (95 % CI, 73.75 %-98.18 %) and the chi-square statistic is 0.1153 ( P = 0.73). Conclusions Our report confirms the diagnostic noninferiority of VEC in preoperative work-up of patients selected for bariatric surgery, compared to EGD. This is very important, particularly during the COVID-19 pandemic, given the high risk of contamination with EGD. Larger multicenter studies are required to confirm our preliminary results.

Abstract
BACKGROUND AND AIM Diagnosis of esophageal squamous cell carcinoma (ESCC) is complicated and requires substantial expertise and experience. This study aimed to develop an artificial intelligence (AI) system for detecting superficial ESCC under multiple endoscopic imaging modalities. METHODS Endoscopic images were retrospectively collected from West China Hospital, Sichuan University as a training dataset and an independent internal validation dataset. Images from other four hospitals were used as an external validation dataset. The AI system was compared with 11 experienced endoscopists. Furthermore, videos were collected to assess the performance of the AI system. RESULTS A total of 53 933 images from 2621 patients and 142 videos from 19 patients were used to develop and validate the AI system. In the internal and external validation datasets, the performance of the AI system under all or different endoscopic imaging modalities was satisfactory, with sensitivity of 92.5-99.7%, specificity of 78.5-89.0%, and area under the receiver operating characteristic curves of 0.906-0.989. The AI system achieved comparable performance with experienced endoscopists. Regarding superficial ESCC confined to the epithelium, the AI system was more sensitive than experienced endoscopists on white-light imaging (90.8% vs 82.5%, P = 0.022). Moreover, the AI system exhibited good performance in videos, with sensitivity of 89.5-100% and specificity of 73.7-89.5%. CONCLUSIONS We developed an AI system that showed comparable performance with experienced endoscopists in detecting superficial ESCC under multiple endoscopic imaging modalities and might provide valuable support for inexperienced endoscopists, despite requiring further evaluation.

Single-Use Versus Reusable Endoscopes for Percutaneous Biliary Endoscopy with Lithotripsy: Technical Metrics, Clinical Outcomes, and Cost Comparison. J Vasc Interv Radiol 2021; 33:420-426. [PMID: 34958859 DOI: 10.1016/j.jvir.2021.12.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 12/06/2021] [Accepted: 12/16/2021] [Indexed: 11/22/2022] Open
Abstract
PURPOSE To compare procedure and fluoroscopy time, technical and clinical success, and costs between single-use and reusable endoscopes in patients undergoing percutaneous biliary endoscopy (PBE) with lithotripsy. MATERIAL AND METHODS In this retrospective study, we included 34 patients (67 procedures) treated with PBE for gallstone removal from October 24, 2014, through February 12, 2020, using reusable (28 procedures) or single-use (39 procedures) endoscopes. We compared 1) procedure time, 2) fluoroscopy time, 3) technical success rate (accessing the biliary system and locating the gallstone), 4) clinical success rate (at least partial gallstone removal), 5) complication rate, and 6) cost of use. Alpha = 0.05. RESULTS Mean (± standard deviation) procedure time was not significantly different between single-use (136 ± 45 minutes) and reusable endoscopes (136 ± 51 minutes) (p = 0.47). Mean fluoroscopy time was significantly shorter for single-use endoscopes (11 ± 8.4 minutes) than for reusable endoscopes (18 ± 12 minutes) (p = 0.01). When comparing single-use vs. reusable endoscopes, rates were not significantly different for technical success (N=37, 95% vs. N=26, 93%) or clinical success (N=35, 90% vs. N=21, 75%) (both, p>0.05). Only 1 complication was noted in the reusable endoscope group (p=0.42). Cost per case was lower for single-use ($1500) than for reusable ($3987) endoscope procedures, primarily due to differences in capital costs and costs due to repair. CONCLUSION Single-use endoscopes offer the potential for less radiation exposure to the patient and lower cost per case, which may reduce financial barriers to offering PBE in interventional radiology practices. Clinical and technical success rates did not differ by endoscope type.

Abstract
Choledochoscopy, or cholangioscopy, is an endoscopic procedure for direct visualization within the biliary tract for diagnostic or therapeutic purposes. Since its conception in 1879, many variations and improvements are made to ensure relevance in diagnosing and managing a range of intrahepatic and extrahepatic biliary pathologies. This ranges from improved visual impression and optical guided biopsies of indeterminate biliary strictures and clinically indistinguishable pathologies to therapeutic uses in stone fragmentation and other ablative therapies. Furthermore, with the evolving understanding of biliary disorders, there are significant innovative ideas and techniques to fill this void, such as nuanced instances of biliary stenting and retrieving migrated ductal stents. With this in mind, we present a review of the current advancements in choledo-choscopy with new supporting evidence that further delineates the role of choledochoscopy in various diagnostic and therapeutic interventions, complications, limitations and put forth areas for further study.

Abstract
Endoscopic submucosal dissection was introduced in Japan for the mini-invasive treatment of early gastric cancer, as part of national screening program considering high prevalence of disease in these latitudes. This technique allows en-bloc curative oncological excision and to obtain in a single step R0-resection, characterization, histological staging and potential cure of the tumor with a very high cost-benefit balance. Over the years, Western endoscopists have adopted endoscopic submucosal dissection, achieving good rates of efficacy, long-term improved outcomes and safety, with low risk of local recurrence comparable to those obtained in Asian institutes. However, according to some authors, the excellent outcomes from East country could not be representative of the Western experience. Despite epidemiological differences of early gastric cancer, scant volume data and limitations in training opportunities between Western and Eastern countries, European Society of Gastrointestinal Endoscopy have adopted Japanese guidelines and developed a European core curriculum for endoscopic submucosal dissection training. Endoscopists should be able to estimate the probability of performing a curative resection by considering the benefit/risk relationship case-by-case in order to implement a correct decision-making process.

Abstract
Liver cirrhosis tends to increase the risk in the management of gastrointestinal tumors. Patients with gastrointestinal cancers and liver cirrhosis often have serious postoperative complications and poor prognosis after surgery. Multiple studies have shown that the stage of gastrointestinal cancers and the grade of cirrhosis can influence surgical options and postoperative complications. The higher the stage of cancer and the poorer the degree of cirrhosis, the less the surgical options and the higher the risk of postoperative complications. Therefore, in the treatment of patients with gastrointestinal cancer and liver cirrhosis, clinicians should comprehensively consider the cancer stage, cirrhosis grade, and possible postoperative complications. This review summarizes the treatment methods of patients with different gastrointestinal cancer complicated with liver cirrhosis.

Abstract
Medical societies and public health agencies rigorously emphasize the importance of adequate disinfection of flexible endoscopes. The aim of this work was to propose a novel opto-chemical disinfection treatment against Staphylococcus aureus grown in mature biofilm on Teflon-based endoscope channel models. Laser irradiation using near-infrared and blue wavelengths combined with a low concentration of chemical disinfectant induced both irreversible thermal denaturation and intercellular oxidative stress as a combined mechanism for an augmented antimicrobial effect. The opto-chemical method yielded a 6.7-log10 reduction of the mature Staphylococcus aureus biofilms (i.e., approximately 1.0-log10 higher than current requirement of standard treatment). The proposed technique may be a feasible disinfection method for mitigating the risk associated with infection transmission.

Abstract
Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are biliary tract pathologies with increased risk of HCC, although HCC is more commonly associated with viral hepatitis and steatohepatitis. HCC risk stratification in PBC/PSC populations may help select patients for surveillance. We hypothesized that metabolic syndrome associated diagnoses and co-morbid nonalcoholic fatty liver disease (NAFLD) may be risk factors for HCC in patients with PBC and PSC. We undertook a multi-institutional case control study of PSC (19 cases, 38 controls) and PBC (39 cases and controls) patients with advanced fibrosis, matched for known HCC risk factors of age and sex, who had native liver explant or resection specimens. In the PSC population, HCC risk was significantly associated with multiple metabolic syndrome associated diagnoses (OR 13, p = 0.02), hyperlipidemia (OR 29, p = 0.03), and obesity (OR 6.8, p = 0.01). In the PBC cohort, only type 2 diabetes was a risk factor for HCC (OR 4.7, p = 0.03). In the PSC cohort, thick fibrous septae were associated with HCC risk (OR 3.4, p = 0.04). No other pathologic features of the nonneoplastic liver were significantly associated with HCC, including features of NAFLD such as macrovesicular steatosis, pericellular fibrosis, and steatohepatitis. Metabolic syndrome associated diagnoses, specifically type 2 diabetes among PBC patients, is associated with HCC risk in patients with biliary type cirrhosis. However, we found no evidence that HCC risk is related to co-morbid NAFLD, indicating a likely distinct mechanism of metabolic syndrome-associated carcinogenesis in these populations.

Abstract
Colorectal cancer (CRC) is the second most common cause of cancer death worldwide, after lung cancer (Sung et al., 2021). Early stage detection is key to increase the survival rate. Colonoscopy remains to be the gold standard procedure due to its dual capability to optically inspect the entire colonic mucosa and to perform interventional procedures at the same time. However, this causes pain and discomfort, whereby it requires sedation or anaesthesia of the patient. It is a difficult procedure to perform that can cause damage to the colonic wall in some cases. Development of new technologies aims to overcome the current limitations on colonoscopy by using advancements in endorobotics research. The design of these advanced medical devices is challenging because of the limited space of the lumen, the contorted shape, and the long tract of the large bowel. The force applied to the colonic wall needs to be controlled to avoid collateral effects such as injuries to the colonic mucosa and pain during the procedure. This article discusses the current challenges in the colonoscopy procedure, the available locomotion technologies for endorobots used in colonoscopy at a prototype level and the commercial products available.

Abstract
Primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC) are immune-mediated chronic liver diseases. PSC is a rare disorder characterized by multi-focal bile duct strictures and progressive liver diseases that ultimately results in the need for liver transplantation in most patients. Imaging studies, such as MRCP, have an essential role in the diagnosis of most cases of PSC. PSC is usually accompanied by inflammatory bowel disease, and there is a high risk of cholangiocarcinoma and colorectal cancer in PSC. No medical therapies have been proven to delay the progression of PSC. Endoscopic intervention for tissue diagnosis or biliary drainage is frequently required in cases of PSC with a dominant stricture, acute cholangitis, or clinically suspected cholangiocarcinoma. PBC is a chronic inflammatory autoimmune cholestatic liver disease, which, when untreated, will culminate in end-stage biliary cirrhosis requiring liver transplantation. A diagnosis is usually based on the presence of serum liver tests indicative of cholestatic hepatitis in association with circulating antimitochondrial antibodies. Patient presentation and course can be diverse in PBC, and risk stratification is important for ensuring that all patients receive a personalized approach to their care. Medical therapy using ursodeoxycholic acid or obeticholic acid has an important role in reducing the progression to end-stage liver disease in PBC.

Abstract
With advancing endoscopic technology and screening protocols for Barrett disease, more patients are being diagnosed with early-stage esophageal cancer. These early-stage patients may be amendable to endoscopic therapies, such as endomucosal resection and ablation. These therapies may minimize morbidity, but the elevated risk of recurrence cannot be overlooked. This article reports outcomes and recommendations for surveillance and management of recurrent esophageal cancer following endoscopic therapies.

Influence of Sedation on the Detection Rate of Early Cancer and Precancerous Lesions During Diagnostic Upper Gastrointestinal Endoscopies: A Multicenter Retrospective Study. Am J Gastroenterol 2021; 116:1230-1237. [PMID: 34074827 DOI: 10.14309/ajg.0000000000001201] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Accepted: 01/22/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION The influence of sedation on the endoscopic detection rate of upper gastrointestinal (UGI) early cancer (EC) and precancerous lesions, including high-grade intraepithelial neoplasia (HGIN) and low-grade intraepithelial neoplasia, has not been assessed. The aim of this research is to assess whether the use of sedation can help improve the detection rate of UGI EC and precancerous lesions. The second objective is to evaluate its potential influencing factors. METHODS The study includes 432,202 patients from a multicenter database from January 2012 to July 2019. Information on endoscopic findings and histology biopsies was obtained from endoscopy quality-control system. Associations of sedation with the detection rate of EC and precancerous lesions were assessed. RESULTS The sedation group has a higher detection rate of UGI EC and HGIN compared with the no-sedation group, whereas the detection rate of low-grade intraepithelial neoplasia was similar between the 2 groups. There were more cases examined by using staining, image enhancement, or magnifying techniques in the sedation group (P < 0.001). And, the mean observation time was also longer in the sedation group (P < 0.001). The type 0-IIb esophageal HGIN and EC cases were significantly increased in the sedation group. No significant difference was detected on lesion subtypes for gastric HGIN and EC according to the Paris classification. More gastric HGIN and EC were detected at gastric body in the sedation group (P = 0.001). DISCUSSION Sedation may improve the endoscopic detection rate of EC and HGIN in the UGI tract probably through enhancing the use of accessary endoscopic techniques, prolonging observation time, and taking more biopsies in different locations (see Visual Abstract, Supplementary Digital Content 2, http://links.lww.com/AJG/B926).

Abstract
Portal vein thrombosis (PVT) is a frequent complication in cirrhotic patients, but it may also exist as a basic vascular condition even without any liver damage. Local and systemic factors play a significant role in the pathogenesis of PVT; yet, in practice, more than one factor may be identified. PVT can be considered a result of liver fibrosis and hepatic insufficiency. The JAK2 mutation has been accepted as a factor producing PVT. In general, the anticoagulants are recommended but this therapy should be used carefully in treating patients that associate coagulopathy or thrombocytopenia and esophageal varices. Acute PVT without bowel infarction has a good prognosis. In liver cirrhosis, the mortality due to hemorrhage is higher than in chronic PVT. Therefore, for the patients with PVT, the survival rate is decreased by 55% in two years, due to hepatic insufficiency. Regarding the treatment, LMWH (low molecular weight heparine) is the most utilized in patients with cirrhosis, non-malignancies, infections, or those who are awaiting a liver transplant. DOACs (direct-acting oral anticoagulants) may be used in the rest of the medical conditions, being safe and equal to LMWH.

Abstract
OBJECTIVES To describe the prevalence of modifiable risk factors for upper digestive tract cancer (UDTC) and its coprevalence, and investigate relevant influencing factors of modifiable UDTC risk factors coprevalence among residents aged 40-69 years in Yangzhong city, China. DESIGN Cross-sectional study. PARTICIPANTS A total of 21 175 participants aged 40-69 years were enrolled in the study. 1962 subjects were excluded due to missing age, marital status or some other selected information. Eventually, 19 213 participants were available for the present analysis. MAIN OUTCOMES MEASURES Prevalence and coprevalence of eight modifiable UDTC risk factors (overweight or obesity, current smoking, excessive alcohol consumption, insufficient vegetables intake, insufficient fruit intake and the consumption of pickled, fried and hot food) were analysed. RESULTS The prevalence of overweight/obesity, current smoking, excessive alcohol consumption, insufficient vegetables intake, insufficient fruit intake and the consumption of pickled, fried and hot food in this study was 45.3%, 24.1%, 16.2%, 66.1%, 94.5%, 68.1%, 36.0% and 88.4%, respectively. Nearly all (99.9%) participants showed one or more UDTC risk factors, 98.6% of the participants showed at least two risk factors, 92.2% of the participants had at least three risk factors and 69.7% of the participants had four or more risk factors. Multivariate logistic regression analysis revealed that men, younger age, single, higher education, higher annual family income and smaller household size were more likely to present modifiable UDTC risk factors coprevalence. CONCLUSIONS The prevalence and coprevalence of modifiable UDTC risk factors are high among participants in Yangzhong city. Extra attention must be paid to these groups who are susceptible to risk factors coprevalence during screening progress. Relative departments also need to make significant public health programmes that aim to decrease modifiable UDTC risk factors coprevalence among residents aged 40-69 years from high-risk areas of UDTC.

Abstract
An aberrant activity of growth factor receptors followed by excessive cell proliferation plays a significant role in pathogenesis of cholangitis. Therefore, inhibition of these processes could be a fruitful therapeutic strategy. The effects of multi-kinase inhibitor 1-(4-Cl-benzyl)-3-chloro-4-(CF3-phenylamino)-1H-pyrrole-2,5-dione (MI-1) on the hepatic and systemic manifestations of acute and chronic cholangitis in rats were addressed. MI-1 (2.7 mg/kg per day) was applied to male rats that experienced α-naphthylisothiocyanate-induced acute (3 days) or chronic (28 days) cholangitis. Liver autopsy samples, blood serum markers, and leukograms were studied. MI-1 localization in liver cells and its impact on viability of HepG2 (human hepatoma), HL60 (human leukemia), and NIH3T3 (normal murine fibroblasts) cell lines and lymphocytes of human peripheral blood (MTT, DNA fragmentation, DNA comet assays, Propidium Iodide staining) were assessed. Under both acute and chronic cholangitis, MI-1 substantially reduced liver injury, fibrosis, and inflammatory scores (by 46-86%) and normalized blood serum markers and leukograms. Moreover, these effects were preserved after a 28-day recovery period (without any treatment). MI-1 inhibited the HL60, HepG2 cells, and human lymphocytes viability (IC50 0.6, 9.5 and 8.3 µg/ml, respectively), while NIH3T3 cells were resistant to that. Additionally, HepG2 cells and lymphocytes being incubated with MI-1 demonstrated insignificant pro-apoptotic and pro-necrotic changes and DNA single-strand breaks, suggesting that MI-1 effects in liver might be partly caused by its cytotoxic action towards liver cells and lymphocytes. In conclusion, MI-1 attenuated the systemic inflammation and signs of acute and chronic cholangitis partly through cytotoxicity towards cells of hepatic and leukocytic origin.

Abstract
BACKGROUND Wireless magnetically controlled capsule endoscopy (WMCCE) was feasible, well tolerated, highly acceptable, and had high consistency in diagnosis of gastric diseases with esophagogastroduodenoscopy (EGD). But WMCCE is not suitable for inspection of the esophagus. We developed detachable string magnetically controlled capsule endoscopy (DS-MCCE) to observe gastroesophageal diseases. METHODS A total of 60 volunteers were enrolled. Thirty participants underwent DS-MCCE, and the other 30 underwent WMCCE. The primary outcome measures included swallowing time, esophageal transit time, the whole examination time, grade of air-bubble interference on esophageal, gastric preparation, visualization of Z-line and gastric mucosa, and discomfort scores. RESULTS The esophageal time (222.53 ± 107.53 s vs. 49.50 ± 34.90 s, P < 0.001) and the whole examination time (26.53 ± 6.33 min vs. 15.97±4.90 min, P < 0.001) in DS-MCCE group were longer than in WMCCE group. DS-MCCE had a significantly better visualization of Z-line visualization. Visualization of the gastric mucosa was assessed as good in 24 (80%) participants for DS-MCCE and 26 (86.6%) for WMCCE, moderate in 6 (20%) with DS-MCCE as compared with 4 (13.3%) with WMCCE. The visualization of gastric cardia for DS-MCCE was better than for WMCCE (100 vs 80%, P = 0.024). The visualization of gastric angle, antrum, and pylorus in DS-MCCE group was not as good as in WMCCE group (80 vs. 100%, 80 vs. 100%, 83.3 vs. 100%, P = 0.024). CONCLUSIONS DS-MCCE is feasible and well tolerated in the diagnosis of gastroesophageal diseases. For people who cannot stand conventional EGD or with contraindication of EGD, DS-MCCE may be an excellent alternative screening modality.

Abstract
Cholestatic liver diseases (CLDs) are a group of diseases characterized by jaundice and cholestasis as the main presentation with different complications, which have considerable impact on the liver and can lead to end-stage liver disease, cirrhosis, and liver-related complications. In the last few years, tremendous progress has been made in understanding the pathophysiology, diagnosis, and treatment of patients with these conditions. However, several aspects related to the management of CLDs remain deficient and unclear. Due to the lack of recommendations that can help in the management, treatment of those conditions, the Saudi Association for the Study of Liver diseases and Transplantation (SASLT) has created a task force group to develop guidelines related to CLDs management in order to provide a standard of care for patients in need. These guidelines provide general guidance for health care professionals to optimize medical care for patients with CLDs for both adult and pediatric populations, in association with clinical judgments to be considered on a case-by-case basis. These guidelines describe common CLDs in Saudi Arabia, with recommendations on the best approach for diagnosis and management of different diseases based on the Grading of Recommendation Assessment (GRADE), combined with a level of evidence available in the literature.

Abstract
BACKGROUND Endoscopic mucosal resection (EMR) is used for the treatment of early esophageal cancer (EEC). METHODS This a retrospective study aimed to study the efficacy, safety, and the recurrence rate of EEC following EMR. RESULTS Seventy-nine patients who had undergone EMR for early EEC (T1a andT1b lesions) from 2006 to 2015 were included. EMR alone was considered curative in 51 patients who had T1a lesion. Complete remission was achieved in 50 (98%) patients. Mean number of sessions of EMR was 1.14. Cancer recurred locally in 6 (12%) of 50 patients at a median follow-up of 48 (18-72) months. Endoscopic treatment alone achieved complete remission at last follow up in 47 of 50 patients (94%) who had initial EMR with complete remission, or in 47 of all 51 patients (92%) in whom EMR was considered curative for EC. The Kaplan-Meier cancer-free survival following complete remission with EMR was 94.2% at 1 year and 88.4% at 5 years. Patients with complete eradication of Barrett's had lower risk of recurrence of adenocarcinoma (AC) compared with patients who had persistent Barrett's (p = 0.01). EMR alone was not considered curative in 19 patients, 16 with T1b AC and 3 with T1a squamous cell carcinoma (SCC) invading the muscularis mucosa (m3). Two major adverse events were noted: delayed bleeding requiring hospitalization, and perforation that was closed endoscopically. CONCLUSION EMR is effective and safe for the management of early EC. The risk of cancer recurrence, albeit small, warrants surveillance. Complete eradication of Barrett's should be attempted in all patients after EMR of AC.

Abstract
Background Endoscopes are widely used for visualizing the respiratory tract, urinary tract, uterus, and gastrointestinal tracts. Despite high demand, people in underdeveloped and developing countries cannot obtain proper access to endoscopy. Moreover, commercially available endoscopes are mostly nonarticulable as well as not actively controlled, limiting their use. Articulating endoscopes are required for some diagnosis procedures, due to their ability to image wide areas of internal organs. Furthermore, actively controlled articulating endoscopes are less likely to harm the lumen than rigid endoscopes because they can avoid contact with endothelial tissues. Objective The study aimed to demonstrate the feasibility and acceptability of smartphone-based wide-field articulable endoscope system for minimally invasive clinical applications in developing and less developed countries. Methods A thin articulable endoscope system that can be attached to and actively controlled by a smartphone was designed and constructed. The system consists of a flexible endoscopic probe with a continuum mechanism, 4 motor modules for articulation, a microprocessor for controlling the motor with a smartphone, and a homebuilt app for streaming, capturing, adjusting images and video, and controlling the motor module with a joystick-like user interface. The smartphone and motor module are connected via an integrated C-type On-The-Go (OTG) USB hub. Results We tested the device in several human-organ phantoms to evaluate the usability and utility of the smartphone-based articulating endoscope system. The resolution (960 × 720 pixels) of the device was found to be acceptable for medical diagnosis. The maximum bending angle of 110° was designed. The distance from the base of the articulating module to the tip of the endoscope was 45 mm. The angle of the virtual arc was 40.0°, for a curvature of 0.013. The finest articulation resolution was 8.9°. The articulating module succeeded in imaging all 8 octants of a spherical target, as well as all 4 quadrants of the indices marked in human phantoms. Conclusions The portable wide-field endoscope was successfully controlled using a smartphone, yielding clear images with a resolution of 960 × 720 pixels at realistic focal distances. Actively and precisely controlled articulating movements have resulted in minimally invasive monitoring in the narrow space of internal organs providing a wide-area view. We found our smartphone-based active articulated endoscope to be suitable for point-of-care applications in developing and less developed countries.

Abstract
Abstract Esophageal cancer is still one of the most common cancers in the world. We review the appropriate treatments at different stages of esophageal cancer and also analyze the advantages and disadvantages of these treatments. The prognosis and recovery of different treatment regimens are further discussed. In particular, post-operative complications are the major causes of high mortality derived from the esophageal cancer. Therefore, we particularly discuss the main complications resulting in high mortality after surgery of esophageal cancer, and summarize their risk factors and treatment options. Background As the common cancer, the complications of esophageal cancer after surgery have been not obtained systematic treatment strategy, focusing on treatment regimens based on the different stages of esophageal cancers. Methods and overview This paper systematically summarizes the appropriate treatment strategies for different stages of esophageal cancers, and their advantages and disadvantages. We particularly focus on the postoperative survival rate of patients and postoperative complications, and discuss the causes of high mortality risk factors after surgery. The risk factors of death and corresponding treatment methods are further summarized in this study. Conclusion Postoperative complications is the main cause responsible for the hard cure of esophageal cancers. The existing literatures indicate that postoperative anastomotic fistula is one of the most important complications leading to death, while it has not received much attention yet. We suggest that anastomotic fistula should be detected and dealt with early by summarizing these literatures. It is, therefore, necessary to develop a set of methods to predict or check anastomotic fistula in advance.
