Sigmoid perforation post laser ablation of fistula in ano. International Journal of Research in Medical Sciences. 2015 June; 3(6): 1551-1553.2320-60712320-6012http://imsear.searo.who.int/handle/123456789/166284Laser ablation of fistula tract is a safe, effective, sphincter-preserving therapy that can be successfully performed by surgeons. Various studies and papers have been published advocating the use of lasers. However clinical experience and technical expertise is necessary for the use of lasers. Here we present a case of a 45 year old male presenting with acute abdomen following laser ablation of fistula in ano. The patients X-Ray abdomen showed free gas under the diaphragm and was explored. The exploration revealed a pyoperitoneum and a sigmoid perforation for which closure of perforation and a diverting colostomy was done. The patient was further operated for fistula excision and Seton suturing and is planned for colostomy closure.enLaser ablationPerforationSigmoid perforationGas under diaphragmArticle
