Objective To observe the transformation features of children with complete atrioventricular block(CAVB), and to improve the diagnosis and treatment of this disease.Methods Seventeen children with primary diagnosis of CAVB were reviewed by retrospective and follow-up study and the clinical characteristics, treatment schemes and prognosis were evaluated.Results Four cases of congenital CAVB lived normally without obvious symptoms in the tracing period from 6 months to 9 years;1 case had the onset of Adams-Stokes syndrome induced by diarrhea;3 cases of the CAVB caused by virus myocarditis turned into sinus rhythm after comprehensive therapy;2 cases persistently presented with the CAVB Complicated with enlarged heart;1 case gave up treatment after deterioration, and one case died.Three cases of temporary CAVB after the open heart operation turned to sinus rhythm in transitory time, while other two cases presented with permanent CAVB and treated with epicardium pacemaker,among whom one had the pacemaker replaced for one time in the 8-year follow-up,and the follow-up of other cases were intermitted.Conclusions The congenital CAVB in the study group with normal QRS interphase and no obvious symptom might not require treatment but follow-up is needed. While infants with heart malformation and wide QRS wave could not endure the low ventricular rhythm are in high risk. Virus myocarditis induced CAVB children tend to present the Adams-Stokes syndrome, and require effective treatments. Partial cases of the CAVB caused by open heart operation may turn to normal sinus rhythm in 2-4 weeks after surgery. cases has persistent CAVB for over 4 weeks, or Adams-Stokes syndrome onset after the surgery demand epicardium pacemaker treatment.

Iatrogenic gastrointestinal perforation is one of the severe adverse events of endoscopic therapeutic procedure. For acute iatrogenic perforation,management by endoscopic techniques is a simple and rapid modality to close the perforation with minimal invasiveness and avoiding the traditional surgical trauma. Endoclips,suture with special instruments,covered stents,degradable sheets combined with tissue adhesive,and combined endoscopic techniques such as snares combined with endoclips,are the major endoscopic therapeutic modalities for closure of iatrogenic gastrointestinal perforation. In this article,the current status and progress of endoscopic management for acute iatrogenic gastrointestinal perforation were reviewed.
