Background
Anastomotic leakage (AL) is one of the most dreadful postoperative complications because it can result in increased morbidity and mortality as well as poorer long-term prognosis. Although most studies of AL limited their investigation time to a period of 30 days postoperatively, only a few studies have shown that AL can occur after that period. Here, we report four patients of rectal cancer with delayed AL following laparoscopic intersphincteric resection (ISR) and conduct a literature review on delayed AL.
Case presentation
Case 1 was a 67-year-old male who underwent laparoscopic partial ISR in July 2009. Although the patient was asymptomatic, an anastomotic-urethral fistula was observed 57 months after ISR. Case 2 was a 44-year-old female who underwent laparoscopic partial ISR in July 2008. She presented with discharge of gas and feces from her vagina, and an anastomotic-vaginal fistula was observed 14 months after ISR. Case 3 was a 74-year-old man who underwent laparoscopic partial ISR in August 2007. He presented with pneumaturia and fecaluria, and an anastomotic-urethral fistula was observed 4 months after ISR. Case 4 was a 68-year-old woman who underwent laparoscopic subtotal ISR for rectal cancer in February 2013 and partial hepatic resection for liver metastases in March 2013. She presented with anal pain and purulent perineal discharge, and an anastomotic-perineal fistula was observed 9 months after ISR. All four cases presented with fistula formation and required reoperation (establishment of a diverting ileostomy).
Conclusions
Since delayed AL is not a rare postoperative complication, surgeons need to provide long-term follow-up and remain alert to the possible development of delayed AL.
