Abstract:
Objective To investigate the efficacy and safety of SB( stag beetle) knife in peroral en?doscopic myotomy( POEM) for achalasia( AC) . Methods A total of 58 cases of AC treated with POEM at department of gastroenterology of the People′s Hospital of Wuhan University from January 2013 to December 2014 were randomly divided into two groups,SB knife group and Dual knife group by using random number table, 29 patients in each group. The complications and therapeutic effects were analyzed. Results All 58 patients with achalasia successfully completed POEM. There were no significant complications in SB knife group such as subcutaneous emphysema, perforation or bleeding.But there were 4 cases of subcutaneous em?physema and 4 cases of bleeding occurred in Dual knife group.The overall incidence of complications was sig?nificantly lower in SB group than that in Dual knife group[0 VS 27?6%(8/29), P<0?05]. The operation time of SB group was(36?32±5?87)mins, which was significant less than that in Dual knife group(56?20± 14?41)mins(P<0?05). The symptom scores significantly increased(P<0?05) and the sphincter resting pressure decreased significantly( P<0?05) after POEM treatment compared with before in the two groups, and there was no statistical significance between the two groups(P>0?05). Conclusion SB knife is safe and effective for achalasia with POEM, which can effectively shorten the operation time and reduce the inci?dence of complications.
