Clinical analysis of delayed hemorrhage after colonoscopic treatment in 45 patients with colonic disease / 重庆医学

ABSTRACT

Objective To analyze the causes of delayed hemorrhage after colonoscopic treatment in colorectal diseases and the value of second colonoscopic treatment.Methods A retrospective study was conducted on 45 patients with colorectal protrusion lesions (polyps,adenoma,early carcinoma and lipoma) in the Daping hospital of the Third Military medical University from January 2010 to December 2016.The patients suffered from delayed hemorrhage after argon knife coagulation,submucosal resection,submucosal dissection or nylon snares colonoscopic treatment.The mode and clinical outcome of second colonoscopic treatment were summarized by aiming at the reasonsof delayed hemorrhage.Results The predilection sites of delayed hemorrhage were in turn rectum (28.89 ％),sigmoid colon (24.44 ％) and ascending colon (22.22 ％).Adenoma and intraepithelial neoplasia lesions were easier to occurr (88.89 ％).The types of delayed hemorrhage were mainly blood oozing at the lesion resection wound surface as well as blood gushing or ejection.The second colonoscopic treatment modes in these cases were mainly titanium clipping and ring clipping and suturing.Five cases were treated by submucosal injection of adrenaline (1 ∶ 10 000) combined with argon knife coagulation.Thirtyfive cases conducted argon knife coagulationcombined with titanium clipping,3 cases conducted titanium clipping and 2 cases adopted ring clipping hemostasis.Forty-two cases stopped bleeding by once colonoscopic treatment,while 3 cases suffered from re-bleeding,the colonoscopic treatment was performed again,1 case stopped bleeding after using titanium clipping and ring clipping hemostasis again,while other 2 cases were transfered to the surgery department for conducting colectomy.All 43 cases of delayed hemorrhage in this group were cured and discharged after successful hemostasis by colonoscopy.The firm wound treatment after colonoscopic treatment was very important for preventing delayed hemorrhage,and the underlying diseases and postoperative diet management were also the important factors of delayed hemorrhage.Conclusion Timely second colonoscopic examination and treatment can obtain satisfactory clinical effects in the patients sufferring from delayed hemorrhage after colonoscopic treatment.
