Anastomotic leakage following surgery is one of the most significant causes of morbidity and mortality. Therefore, prevention of anastomotic leakage is crucial for safe rectal surgery. The aim of this study is to determine the effect of Mallecot(R) insertion on the prevention of anastomotic leakage after low rectal anastomosis.
From January 2002 to December 2006, 264 rectal cancer surgeries were performed in one center and by one surgeon. Among them, 110 cases whose anastomosis was located below 6 cm from the anal verge were collected and reviewed retrospectively. We made a diverting stoma on 6 out of 20 patients with high risk of anastomotic leakage, and inserted Mallecot(R) on the remaining 14 patients transanally. Removal of Mallecot(R) was done at the 7th postoperative day after a digital rectal examination to identify the completeness of anastomosis had been performed.
Totally, anastomotic leakage occurred in 8 of 110 patients (73%). Among the 90 patients without any preventive measures, 7 incidents of anastomotic leakage were observed; on the other hand, 1 of 14 patients with Mallecot(R) insertion suffered anastomotic leakage. In two of the patients with leakage, including 1 in the Mallecot(R) group, the leakage was resolved via percutaneous drainage; in the other 6 patients were reoperated.
The importance of preventing an anastomotic leakage after low rectal surgery cannot be overemphasized to reduce morbidity and to improve the prognosis. In addition, Mallecot(R) insertion may be an alternative method for diverting stoma formation.
