Complications associated with ultra-low anastomosis after robotic intersphincteric resection for low rectal cancer
To investigate the complications associated with ultra-low anastomosis in robotic intersphincteric resection for rectal cancer and analyze their clinical characteristics for their prevention and treatment.
Methods
2
We retrospectively analyzed the clinical data of 43 patients undergoing robotic intersphincteric resection for low rectal cancer in our hospital between January
2015 and March
2019. The patients were followed up after the surgeries
via
outpatient visit and by telephone to assess the occurrence of anal stenosis
edematous hemorrhoids
partial intestinal obstruction
rectovaginal fistula
anastomotic leakage
and rectal mucosal prolapse. The surgical and perioperative data including intraoperative blood loss
operative time
defecation time
time to normal diet
postoperative hospital stay
postoperative pathology
the number of lymph nodes involved
and distal resection margin were also analyzed for the patients.
Results
2
All the patients underwent robotic intersphincteric resection and prophylactic ileostomy. Postoperative anal stenosis (mainly membranous stenosis) was found in 19 patients (44.2%) after the surgery
and was relieved by regular anal expansion. Postoperative edematous hemorrhoids were found in 14 patients (32.6%) and remitted at a median of 33 d (range 16-64 d) after the operation. Among the 10 patients with partial intestinal obstruction
1 patient underwent closure of ileostomy 35 d after operation
which was before the scheduled time; and in the remaining patients
ileostomy was closed by elective surgery after conservative treatment. Two patients experienced anastomotic leakage and 1 patient had rectovaginal fistula after the surgery (delayed fistula). No rectal prolapse occurred in these patients. Univariate logistic regression analysis showed that the male gender was an independent risk factor for anal stenosis (
P
=0.002)
and the incidence of edematous hemorrhoids was correlated with the operation time (
P
=0.005).
Conclusion
2
Anal stenosis
edematous hemorrhoids
and partial intestinal obstruction are the most common complications associated with ultra-low anastomosis after robotic intersphincteric resection surgery for rectal cancer
and early preventive measures and active interventions can achieve favorable outcomes.
