AIM: To evaluate the efficacy of resection and primary anastomosis (RPA) and RPA with modified blow-hole colostomy for sigmoid volvulus.METHODS: From March 2000 to September 2007,77 patients with acute sigmoid volvulus were treated.A total of 47 patients underwent RPA or RPA with modified blow-hole colostomy.Twenty-five patients received RPA (Group A),and the remaining 22 patients had RPA with modified blow-hole colostomy (Group B).The clinical course and postoperative complications of the two groups were compared.RESULTS: The mean hospital stay,wound infection and mortality did not differ significantly between the groups.Superficial wound infection rate was higher in group A (32% vs 9.1%).Anastomotic leakage was observed only in group A,with a rate of 6.3%.The difference was numerically impressive but was statistically not significant.CONCLUSION: RPA with modified blow-hole colostomy provides satisfactory results.It is easy to perform and may become a method of choice in patients with sigmoid volvulus.Further studies are required to further establish its role in the treatment of sigmoid volvulus.
