BACKGROUND Lipid metabolism reprogramming is suspected to exist in pre-cancerous lesions,including colorectal adenoma.Screening colonoscopy frequently reveals chicken skin mucosa(CSM;white or yellow-white speckled mucosa)surrounding colo-rectal polyps,caused by macrophages engulfing and accumulating the lipids decomposed by colon cells or adjacent tumors.CSM-positive colorectal polyps are associated with various diseases;however,their prognosis varies greatly.Cold snare polypectomy is commonly used to resect lesions up to 10 to 15 mm in diameter without signs of submucosal invasion but is controversial for CSM-positive colorectal polyps.Improved imaging is required to diagnose and treat CSM-positive colorectal polyps.METHODS This retrospective cohort study included 177 patients with CSM-positive colorectal polyps diagnosed using endoscopy.All patient-related information was extracted from the Goldisc soft-clinic DICOM system or electronic medical record system.Based on the pathological results,patients were classified as non-neoplastic polyps(five juvenile polyps),neoplastic polyps,non-invasive high-grade neoplasia(NHGN),or submucosal invasive carcinoma(SM stage cancer).We analyzed and compared the clinical features,suspected risk factors for malignant transformation of neoplastic polyps,and early infiltration of sub-mucosal carcinoma.RESULTS The diameters of NHGN and SM polyps were much smaller than those of neoplastic polyps.Most NHGN polyps had a deeper red mucosal color.On logistic regression analyses,diameter and deeper red mucosal color were independent risk factors for malignant transformation of neoplastic polyps.Type 1 CSM was more common in high-grade intraepithelial neoplasia and SM;type 2 CSM was more common in neoplastic polyps.Logistic regression analyses revealed no significant differences in the malignant transformation of neoplastic polyps or early submucosal invasion of CSM-positive colorectal cancer.Changes in the CSM mucosa surrounding neoplastic polyps and submucosal invasion of colorectal cancer disappeared within 12 months.No tumor recurrence was found during either partial or complete endoscopic resection of the CSM.CONCLUSION CSM-positive colorectal polyps>1 cm in diameter or with deeper red mucosa may be related to NHGN.Resection of CSM surrounding colorectal adenomas did not affect tumor recurrence. 展开更多

BACKGROUND The metastatic tumors in the small intestine secondary to extra-abdominal/extrapelvic malignancy are extremely rare.However,the small intestine metastases are extremely prone to misdiagnosis and missed diagnosis due to the lack of specific clinical manifestations and examination methods,thus delaying its treatment.Therefore,in order to improve clinical diagnosis and treatment capabilities,it is necessary to summarize its clinical pathological characteristics and prognosis.AIM To summarize the clinicopathological characteristics of patients with small intestinal metastases from extra-abdominal/extra-pelvic malignancy,and to improve the clinical capability of diagnosis and treatment for rare metastatic tumors in the small intestine.METHODS The clinical data of patients with small intestinal metastases from extra-abdominal/extra-pelvic malignancy were retrieved and summarized,who admitted to and treated in the Air Force Medical Center,Chinese People’s Liberation Army.Then descriptive statistics were performed on the general conditions,primary tumors,secondary tumors in the small intestine,diagnosis and treatment processes,and prognosis.RESULTS Totally 11 patients(9 males and 2 females)were enrolled in this study,including 8 cases(72.3%)of primary lung cancer,1 case(9.1%)of malignant lymphoma of the thyroid,1 case(9.1%)of cutaneous malignant melanoma,and 1 case(9.1%)of testicular cancer.The median age at the diagnosis of primary tumors was 57.9 years old,the median age at the diagnosis of metastatic tumors in the small intestine was 58.81 years old,and the average duration from initial diagnosis of primary tumors to definite diagnosis of small intestinal metastases was 9 months(0-36 months).Moreover,small intestinal metastases was identified at the diagnosis of primary tumors in 4 cases.The small intestinal metastases were distributed in the jejunum and ileum,with such clinical manifestations as hematochezia(5,45.4%)and abdominal pain,vomiting and other obstruction(4,36.4%).In addition,2 patients had no obvious symptoms at the diagnosis of small intestinal metastases,and 5 patients underwent radical resection of small intestinal malignancies and recovered well after surgery.A total of 3 patients did not receive subsequent treatment due to advanced conditions.CONCLUSION Small intestinal metastases of extra-abdominal/extra-pelvic malignancy is rare with high malignancy and great difficulty in diagnosis and treatment.Clinically,patients with extra-abdominal/extra-pelvic malignancy should be alert to the occurrence of this disease,and their prognosis may be improved through active surgery combined with standard targeted therapy. 展开更多

BACKGROUND Genetic factors of chronic intestinal ulcers are increasingly garnering attention.We present a case of chronic intestinal ulcers and bleeding associated with mu-tations of the activin A receptor type II-like 1(ACVRL1)and phospholipase A2 group IVA(PLA2G4A)genes and review the available relevant literature.CASE SUMMARY A 20-year-old man was admitted to our center with a 6-year history of recurrent abdominal pain,diarrhea,and dark stools.At the onset 6 years ago,the patient had received treatment at a local hospital for abdominal pain persisting for 7 d,under the diagnosis of diffuse peritonitis,acute gangrenous appendicitis with perforation,adhesive intestinal obstruction,and pelvic abscess.The surgical treat-ment included exploratory laparotomy,appendectomy,intestinal adhesiolysis,and pelvic abscess removal.The patient’s condition improved and he was dis-charged.However,the recurrent episodes of abdominal pain and passage of black stools started again one year after discharge.On the basis of these features and results of subsequent colonoscopy,the clinical diagnosis was established as in-flammatory bowel disease(IBD).Accordingly,aminosalicylic acid,immunotherapy,and related symptomatic treatment were administered,but the symptoms of the patient did not improve significantly.Further investigations revealed mutations in the ACVRL1 and PLA2G4A genes.ACVRL1 and PLA2G4A are involved in angiogenesis and coagulation,respectively.This suggests that the chronic intestinal ulcers and bleeding in this case may be linked to mutations in the ACVRL1 and PLA2G4A genes.Oral Kangfuxin liquid was administered to promote healing of the intestinal mucosa and effectively manage clinical symptoms.CONCLUSION Mutations in the ACVRL1 and PLA2G4A genes may be one of the causes of chronic intestinal ulcers and bleeding in IBD.Orally administered Kangfuxin liquid may have therapeutic potential. 展开更多

BACKGROUND Gallbladder perforation is a serious complication of acute cholecystitis.Such perforation is a rare but life-threatening situation that can lead to the formation and rupture of liver hematomas.Here,we report a case of a ruptured intrahepatic hematoma caused by intrahepatic gallbladder perforation,and we present a literature review.CASE SUMMARY A 70-year-old male was admitted to the hospital with a complaint of right upper quadrant abdominal pain,flustering and dizziness.The preoperative diagnosis was a ruptured malignant liver tumor,and the patient’s medical images and increased level of carbohydrate antigen-199 suggested that the gallbladder had been invaded.However,the tumor was proven to be a liver hematoma secondary to gallbladder perforation after surgery.The patient was discharged uneventfully on the fifteenth postoperative day.CONCLUSION Intrahepatic gallbladder perforation is difficult to diagnose preoperatively.Radiological examinations play a crucial role in the diagnosis but only for partial cases.Early diagnosis and appropriate surgery are key to managing this rare condition. 展开更多

BACKGROUND Small bowel tumors(SBTs)are a heterogeneous group of difficult-to-diagnose tumors that account for 2%-5%of all gastrointestinal tumors.Single-balloon enteroscopy greatly enhances the diagnosis and treatment of SBTs.However,few epidemiological studies have been conducted in Taiwan to determine the clinical profile of SBTs.AIM To investigate the clinical characteristics,managements and prognosis of SBTs in a medical center in Taiwan.METHODS The study enrolled 51 patients aged 58.9±8.8 years(range,22-93)diagnosed with SBTs from November 2009 to July 2021.We retrospectively recorded clinical characteristics,indications,endoscopic findings,pathological results,management,and outcomes for further analysis.RESULTS A male preponderance was observed(56.8%).The most common indications were suspected small intestinal tumors(52.9%)and obscure gastrointestinal bleeding(39.2%).The most common tumor location was the ileum(41.2%).The performance of imaging studies(P=0.004)and the types of findings(P=0.005)differed significantly between malignant and benign SBTs.The most frequent imaging finding was a small intestinal mass(43.1%).The top three malignant tumor types were gastrointestinal stromal tumors(GISTs),adenocarcinomas,and lymphomas.Moreover,the proportions of benign and malignant tumors were 27.5%and 72.5%,respectively.The survival rates of patients with malignant tumors in the GIST and non-GIST groups differed significantly(P=0.015).Kaplan–Meier survival analysis showed a significant difference in survival between patients in the malignant and benign groups(P=0.04).All patients with lymphoma underwent chemotherapy(n=7/8,87.5%),whereas most patients with GISTs underwent surgery(n=13/14,92.8%).CONCLUSION Patients with GISTs have a significantly higher survival rate than those with other malignant SBTs.Therefore,a large-scale nationwide study is warranted to evaluate the population-based epidemiology of SBTs. 展开更多
