Port-site non-tuberculous mycobacterial infection after laparoscopic cholecystectomy: a case series study

ABSTRACT

Port-site infection by mycobacterial organism is an unusual complication. This article aims to report the occurrence of port-site mycobacterial infection after laparoscopic cholecystectomy and to describe the diagnostic and therapeutic tools of this unusual complication. This case series study included 7 cases presented by port-site unhealed sinuses after laparoscopic cholecystectomy in Al-Azhar University hospital, Cairo, Egypt. Two methods were used to confirm the diagnosis; the bacteriological diagnosis by culture of pus collected from the port-site and histopathological examination of specimens after resection of port-site unhealed sinuses. Bacteriological and histopathological examinations showed the presence of mycobacterial infection in 4 cases [57,1%]. There was a special characteristic picture on sinogram and during surgical excision of the sinuses. All cases cured by meticulous surgery followed by anti-mycobacterial medications. Mycobacterial infection may be one of the causes of port-site delayed wound healing and the treatment should mainly depend on good meticulous surgical excision
