ABSTRACT
Objective To investigate the clinical characteristics and analyze the influencing factors of colorectal polyp recurrence after polypectomy.Methods The clinical data of colorectal polyps patients,who underwent colonoscopic polypectomy in our hospital and received a follow-up colonoscopy within 2 years [mean interval (18.8 ± 8.42) months] were collected between January 2012 and August 2015 (n =194).The polyps size,number,location,and pathology were detected.The polyps recurrence rate and influencing factors were analyzed.Results The polyps recurrence rate was 71.6％ (139/194) in 2 years.The patients,who aged ≥60 years,with adenoma number≥3,located in the left hemicolon and rectum,were easier to recurrence (P ＜ 0.05).Logistic regression analysis revealed that age and number of adenomas were independent factors of polyps recurrence whereas the sex,size,location,and pathology were not (P ＜ 0.05)during the surveillance interval.However,19.4％ nonneoplastic-polyp group and 15.5％ low-risk group turn into bad side.Conclusions The outcomes indicate that age and number of adenomas ≥3 were independent factors of polyps recurrence,whereas the size and pathological type were limited in risk stratification for patients after polypectomy.Two year may be the appropriate interval for endoscopic rescreening.
ABSTRACT
Objective To research early pathological morphology and clinical significance of perforated duodenal ulcer (PDU) closed after non-surgical treatment. Methods Observed morphological changes of duodenal ulcer (DU) lesion with gastroscopy for 302 patients of PDU with non-surgical treatment in early period,when the perforation closed and measured up the clinical indicators during this hospitalization.Results There were 255 patients to be diagnosed with DU caused the perforation. These lesions were characteristic and shown the PDU closed at the bottom and the deep concave ulcers, except for 1 case which complicated by duodenal fistula. These ulcer types were diverse according to the time difference after treatment. No case of re-perforated ulcers or recurrence of peritonitis caused by gastroscopy. Conclusions Deep concave ulcer with A1 phase mainly is an early pathological manifestations of the DU after treated the PDU with non-surgical method characteristically. The wall of the closure of the serosal side is an original form closed perforated ulcer by non-surgical treatment. The risk of perforation associated with the following factors:( 1 )A single DU is located in the anterior wall region. (2)The shape of two kissing DU. (3)The diameter of DU ≥ 1.1 cm. In this case,early diagnosis by using endoscopy is a safe way.
ABSTRACT
OBJECTIVE To discuss the related factors of toxigenic Helicobacter pylori(Hp) infection among adult population in Futian District,Shenzhen.METHODS A total of 1164 adults who had health examination in community centers were investigated through questionnaire and detected Hp antibodies.RESULTS The Hp and toxigenic Hp infection rates among them were 45.5% and 14.2%.Among them 46.3% and 14.8% were in males,and 44.7% and 13.4% in females.People less than 60 years old had higher incidence of Hp and toxigenic Hp,but decrease in people rnore than 60 years old.Hp and toxigenic Hp infection rate in married people were higher than those of unmarried.In workers,farmers and doctors were higher than staff and other occupations.The incidence were higher in drinking raw water than those drinking boiling water.in taking antibiotics before serologic examination were lower than no taking antibiotics;in peptic ulcer disease were higher than in no peptic ulcer disease;in per capita housing area over 6 m2 were higher than less 6 m2.CONCLUSIONS The infection rates of Hp and toxigenic Hp among our adult population are low,and positively correlated with age but gender.The social environment such as living condition,economic income,culture level and residential density maybe influence the infection of Hp.The route of transmission of Hp is unknown yet,water perhaps is an important dissemination medium.
ABSTRACT
Objective To explore the value of gastroendoscopy check-up early after non-surgical treatment of patients with gastroduodenal perfolation.Methods The patients suspected of perforated gastroduodenal ulcer on hospital admission underwent non-surgical treatment were enrolled.After cured clinically,performed gastroendoscopy at different time periods.Results Among 133 patients underwent gastrointestinal endoscopy,129 cases(97.0%)were diagnosed gastroduodenal ulcer,3 cases(2.3%)were diagnosed gastric carcinoma,1 case (0.8%)Was confirmed duodenal diverticulum,no compilcations occurred due to endoscopy.The 6 cases that had surgical indications had be implemented the early surgical treatment. Conclusions After non-surgical treatment of patient with gastroduodenal perforation,timely gsstroendoscopy can truly show pathologic changes with gastroduodenal perforation.So endoscopy is beneficial under condition appropriate time seleetion for confirmed the eliology of PGD,treatment promptly targeted etiology and understanding the mechanism healing the perforation as non-surgical treatment.
