Anastomotic leak (AL) after low anterior resection (LAR) can be a highly morbid complication. The incidence of AL ranges from 5% to 20% depending on patient characteristics and the distance of the anastomosis from the anal verge. Low anastomoses and leaks pose technical challenges for endoscopic treatment. The aim of this report was to describe the use of a commercially available laparoscopic energy device through a transanal minimally invasive surgery (TAMIS) port for the management of a symptomatic leak not requiring relaparotomy (grade B) after a LAR with diverting loop ileostomy.
A TAMIS GelPOINT Path port was inserted into the anus to access the distal rectum. Pneumorectum was achieved with AirSeal insufflation and a 30 degree laparoscope was introduced through a trocar. A LigaSureTM Retractable L-Hook device was then used to perform a septotomy of the chronic sinus tract identified posterior to the coloproctostomy. The procedure was then repeated twice in three weeks intervals with ultimate resolution of the chronic leak cavity. Several months after serial TAMIS septotomies, barium enema demonstrated a patent anastomosis with no evidence of persistent leak or stricture. The patient subsequently underwent ileostomy reversal and has had no significant post-operative issues.
TAMIS septotomy with the LigaSureTM Retractable L-Hook is a feasible and effective, minimally invasive salvage technique for the treatment of grade B ALs. Larger studies are needed to assess the generalizability and long-term results of this technique.
Core tip: Anastomotic leaks (ALs) after low anterior resection for the treatment of rectal cancer are highly morbid complications and often pose a technical challenge for its treatment. We report a case of a transanal minimally invasive septotomy of a chronic sinus secondary to an AL, with the use of the Ligasure retractable L-Hook device. This safe and effective technique may help avoid re-operations which are associated with higher mortality and higher permanent stoma rates.
