Application of artificial intelligence to endoscopy on common gastrointestinal benign diseases

Artificial intelligence(AI)has been widely involved in every aspect of healthcare in the preclinical stage.In the digestive system,AI has been trained to assist auxiliary examinations including histopathology,endoscopy,ultrasonography,computerized tomography,and magnetic resonance imaging in detection,diagnosis,classification,differentiation,prognosis,and quality control.In the field of endoscopy,the application of AI,such as automatic detection,diagnosis,classification,and invasion depth,in early gastrointestinal(GI)cancers has received wide attention.There is a paucity of studies of AI application on common GI benign diseases based on endoscopy.In the review,we provide an overview of AI applications to endoscopy on common GI benign diseases including in the esophagus,stomach,intestine,and colon.It indicates that AI will gradually become an indispensable part of normal endoscopic detection and diagnosis of common GI benign diseases as clinical data,algorithms,and other related work are constantly repeated and improved.

Review of oral and pharyngolaryngeal benign lesions detected during esophagogastroduodenoscopy

Recent advancements in endoscopy equipment have facilitated endoscopists’detection of neoplasms in the oral cavity and pharyngolaryngeal regions.In particular,image-enhanced endoscopy using narrow band imaging or blue laser imaging play an integral role in the endoscopic diagnosis of oral and pharyngolaryngeal cancers.Despite these advancements,limited studies have focused on benign lesions that can be observed during esophagogastroduodenoscopy in the oral and pharyngolaryngeal regions.Therefore,this mini-review aimed to provide essential information on such benign lesions,along with representative endoscopic images of dental caries,cleft palate,palatal torus,bifid uvula,compression by cervical osteophytes,tonsil hyperplasia,black hairy tongue,oral candidiasis,oral and pharyngolaryngeal ulcers,pharyngeal melanosis,oral tattoos associated with dental alloys,retention cysts,papilloma,radiation-induced changes,skin flaps,vocal cord paresis,and vocal fold leukoplakia.Whilst it is imperative to seek consultation from otolaryngologists or dentists in instances where the diagnosis cannot be definitively ascertained by endoscopists,the merits of attaining foundational expertise pertaining to oral and pharyngolaryngeal lesions are unequivocal.This article will be a valuable resource for endoscopists seeking to enhance their understanding of oral and pharyngolaryngeal lesions.

Downregulation of serum mi R-17 and mi R-106b levels in gastric cancer and benign gastric diseases

Altered micro RNA（mi RNA） associated with gastric cancer（GC） development and mi R-17 and mi R-106 b were differentially expressed in GC tissues. This study detected serum levels of mi R-17 and mi R-106 b expression in GC, benign gastric disease（BGD） and healthy controls to assess them as tumor markers for GC. Serum samples from 40 GC, 32 BGD（10 gastric ulcer, 14 gastric polyps, and 8 gastric ulcer with polyps） and 36 healthy individuals were subjected to quantitative reverse transcription polymerase chain reaction（q RT-PCR） analysis of mi R-17 and mi R-106 b expression. The data showed that the serum levels of mi R-17 and mi R-106 b were significantly reduced in healthy individuals and BGD patients compared to GC patients. There was a significant association of mi R-17 and mi R-106 b expression with age, but not with other clinicopathological features, such as gender, tumor differentiation, stage and lymphatic metastasis. Further analysis showed that, in discriminating GC patients from healthy controls, mi R-17 could yield a receiver-operating characteristic（ROC） area under the curve（AUC） of 0.879 with 80.6% sensitivity and 87.5% specificity and mi R-106 b could yield an AUC of 0.856 with 75.0% sensitivity and 92.5% specificity. The combined AUC of mi R-17 and mi R-106 b was 0.913 with 83.3% sensitivity and 87.5% specificity. Collectively, these data suggest that detection of serum mi R-17 and mi R-106 b levels should be further evaluated as novel non-invasive biomarkers in early GC detection and surveillance of disease progression.

Expression and Clinical Significance of Vascular Endothelial Growth Factor in Benign and Malignant Tissues of Breast

Objective： To detect the expression of vascular endothelial growth factor （VEGF） and microvessel density （MVD） count in breast benign affection, breast atypical hyperplasia and breast carcinoma in situ, and to clarify the relationship between VEGF expression, MVD and the clinicopathological features of these diseases. Methods： The expression of VEGF and MVD count in 115 cases breast benign diseases （including 40 breast fibroid tumor, 40 breast cystic hyperplasia and 35 intraductal papilloma, 19 breast atypical hyperplasias and 32 breast carcinomas in situ were examined by immunohistochemistry staining （SP-method）. Results： The positive rate of VEGF in breast benign diseases, breast atypical hyperplasia and breast carcinoma in situ were 21.74%（25/115）, 31.58.% （6/19）and 53.13%（17/32） respectively. It was the lowest in breast benign affection group, and was the highest breast carcinoma in situ group. The expression of VEGF increased gradually in the three groups （P〈0.05）. The MVD count of the three groups were 14.41 ± 2.59, 18.89± 4.47 and 21.13 ± 4.12 respectively, It was the lowest in breast benign affection group, and was the highest breast carcinoma in situ group. The MVD count of the three groups increased gradually （P〈0.05）. In VEGF positive group, MVD count was 19.41 ±4.78; In VEGF negative group, MVD count was 14.91±3.15. The MVD count was higher in VEGF positive group than that in VEGF negative group （P〈0.05）. Conclusion： The results of this study suggested that VEGF could promote microvessel growth in breast tumors. The occurrence and progression of breast cancer might be related with the expression of VEGF.

Comparison of the short-term and long-term outcomes of laparoscopic hysterectomies and of abdominal hysterectomies： a case study of 4,895 patients in the Guangxi Zhuang Autonomous Region, China

Background： To evaluate the short-term and long-term outcomes after laparoscopic hysterectomy （LH） compared with abdominal hysterectomy （AH） in case of benign gynecological disease. Methods： A multi-center cohort retrospective comparative study of population among 4,895 hysterectomies （3,539 LH vs.1,356 AH） between 2007 and 2013 was involved. Operative time （OT）, estimated blood loss （EBL）, intra-operative and post-operative complications, passing flatus; days with indwelling catheter, questionnaires covering pelvic floor functions and sexual functions were assessed. Results： The EBL （174.1±157.4 vs. 263.1±183.2 cc, LH and AH groups, respectively）, passing flatus （38.7±14.1 vs. 48.1±13.2 hours）, days with indwelling catheter （1.5±0.6 vs. 2.2±0.8 days）, use of analgesics （6.5% vs. 73.1%）, intra-operative complication rate （2.4% vs. 4.1%）, post-operative complication rate （2.3 % vs. 5.7%）, post-operative constipation （12.1% vs. 24.6%）, mild and serious stress urinary incontinence （SUI） post-operative （P〈0.001; P=0.014）, and proportion of Female Sexual Functioning Index （FSFI） total score 〈26.55 post-operative （P〈0.001） of the LH group were significantly less than those of AH group. There were no significant differences in OT （106.5±34.5 vs. 106.2±40.3 min） between the two groups. Conclusions： LH is a safe and efficient operation for improving patients＇ long-term quality of life （QoL）, and LH is a cost-effectiveness procedure for treating benign gynecological disease. LH is superior to AH due to reduced EBL, reduced post-operative pain and earlier passing flatus.

Health-related quality of life after liver transplantation: the experience from a single Chinese center

BACKGROUND: Few studies have been performed to assess health-related quality of life (HRQOL) in liver transplantation (LT) patients in the mainland of China. This study aimed to investigate the HRQOL of post-LT patients in a single center. METHODS: HRQOL was evaluated by the SF-36 (Chinese version) questionnaire in 60 patients (LT group) who had received LT for benign end-stage liver disease (BELD). Fifty-five patients with BELD (BELD group) and 50 healthy volunteers from the general population (GP group) were also evaluated, and the results were compared among the three groups. RESULTS: There was a significant difference among the three groups in terms of the scores of eight domains in the SF-36 (P<0.01). Patients in the BELD group had lower scores in each domain of the SF-36 in comparison with those in the GP group (P<0.025). The LT group had mental health scores equivalent to those of the BELD group (P>0.025), but higher scores for the remaining seven domains (P<0.025). Compared with the GP group, the LT group scored equivalently for role physical, body pain, vitality, social function and role emotion (P>0.025), but had lower scores for the remaining three domains (P<0.025). Lower family income was found to be associated with reduced physical function and mental health scores (P<0.05). Better education was associated with increased mental health scores (P<0.05). CONCLUSIONS: LT patients generally have a good HRQOL although some respects of their HRQOL remains to be improved. Lower family income and poor education are important factors relating to the poor HRQOL of LT patients.
