Introduction
!
Since the first descriptions of endoscopic colorec-
tal stenting [1, 2], the procedure has become com-
mon in clinical practice [3, 4]. Anastomotic com-
plications after colorectal resection represent a
challenging problem. In the past 13 years, 170 pa-
tients with colorectal obstruction underwent
placement of a self-expanding metal stent
(SEMS) in our Endoscopy Section. Among those
patients, 16 patients underwent SEMS placement
to treat anastomotic stricture after anterior rectal
resection. In nine of the patients the stricture was
associated with anastomotic fistula. Results from
these 16 patients are presented in this case series.
Patients and methods
!
All patients who underwent placement of SEMS
for anastomotic stricture with or without fistula
were included in this study. No patient was ex-
cluded. During an 8-year period (2005 – 2012),
16 consecutive patients underwent SEMS place-
ment for anastomotic stricture after anterior rec-
tal resection. The study was approved by the Hos-
pital Ethics Committee and all patients were fully
informed and gave informed consent for the pro-
cedure.
Therapeutic strategy in patients with
simple anastomotic stricture
Seven patients had only a stricture without fistu-
la. In four patients, previous balloon dilation had
failed. Three patients had previously undergone
a diverting proximal stoma procedure to treat an
episode of acute obstruction. Patients were ad-
mitted to the hospital and the day before the pro-
cedure they received a light rectal enema, which
was repeated just before the procedure. The stent
was placed with the patient under conscious se-
dation with benzodiazepine, according to body
weight. At 3 months after stent placement, cov-
ered stents were removed from patients; uncov-
ered stents remained in place. If there was no evi-
dence of residual obstruction, the stoma, if pres-
ent, was closed.
Therapeutic strategy in patients with
anastomotic stricture and fistula
Nine patients had a fistula associated with the
anastomotic stricture. Patients were admitted to
the hospital. A diverting proximal stoma was per-
formed before insertion of the stent in six pa-
tients (ileostomy in five patients and colostomy
in one patient); the three other patients did not
have a stoma. The stent was placed with the pa-
tient under conscious sedation with benzodiaze-
pine, according to body weight. A barium control
enema 4 months later was performed to check for
anastomotic leakage. If no leak was observed the
stoma was closed and 2 weeks later the stent was
removed endoscopically, unless it had been pre-

Self-expanding metal stents (SEMS) can be used
to treat patients with symptomatic anastomotic
complications after colorectal resection. In the
present case series, 16 patients with symptomatic
anastomotic stricture after colorectal resection
were treated with endoscopic placement of
SEMS. Seven patients had a “simple” anastomotic
stricture and nine patients had a fistula associat-
ed with the stricture. The anastomotic fistula
healed without evidence of residual stricture or
major fecal incontinence in seven of the nine pa-
tients. Overall the anastomotic stricture was re-
solved in 10 of the 16 patients. SEMS placement
represents a valid adjunctive to treatment in pa-
tients with symptomatic anastomotic complica-
tions after colorectal resection for cancer.
