Original Article



Lateral lymph node dissection (LLND) is performed for advanced lower rectal cancer (ALRC) in Japan. The LLND in laparotomy is performed via the extraperitoneal approach, which is similar to radical retropubic prostatectomy (RRP). Inguinal hernias (IHs) appearing after RRP are common. However, there are few reports about IHs appearing after LLND.


In part A, we retrospectively investigated 108 patients who underwent LLND for ALRC between January 2004 and December 2014. In part B, we compared 13 patients who underwent IH repair after LLND and 57 patients who underwent IH repair after RRP in the same period.


In part A, the incidence of IHs after LLND was 7% (8/108). All eight patients who developed IHs were male, and their median age was 60 years. More than 80% of IHs observed were the unilateral lateral type. In part B, the interval between the previous operation and IH occurrence was 4.9 years on average. Furthermore, 2 out of the 13 patients developed additional IHs occurring on the opposite side within 2 years.


The characteristics associated with developing IHs after LLND were similar to those after RRP. Any pelvic operation via the extraperitoneal approach has a risk of IHs, and surgeons should pay attention to IHs after surgery.
