PurposeIn this retrospective study, we aimed to compare the clinical characteristics of inguinal hernia developed after radical retropubic surgery for prostate cancer to the hernia without previous radical prostatectomy.MethodsTwenty-three patients (group A) who had radical retropubic surgery for prostate cancer underwent laparoscopic or open tension-free inguinal hernia repair from March 2007 to February 2011. Nine hundred and forty patients (group B) without previous radical retropubic surgery received laparoscopic or tension-free open hernia operation.ResultsGroup A was older than group B (mean ± standard deviation, 69.6 ± 7.2 vs. 54.1 ± 16.1; P < 0.001). Right side (73.9%) and indirect type (91.3%) in group A were more prevalent than in group B (51.5% and 69.4%, respectively) with statistic significance (P = 0.020 and P = 0.023). The rate of laparoscopic surgery in group B (n = 862, 91.7%) was higher than in group A (n = 14, 64.3%, P < 0.001). In comparing perioperative variables between the two groups, operative time (49.4 ± 23.5 minutes) and hospital stay (1.9 ± 0.7 days) in group A were longer than in group B (38.9 ± 16.9, 1.1 ± 0.2; P = 0.046 and P < 0.001, respectively) and pain score at 7 days in group A was higher than in group B (3.1 ± 0.7 vs. 2.3 ± 1.0, P < 0.001). Postoperative recurrence rate was not significantly different between the two groups.ConclusionInguinal hernia following radical retropubic surgery for prostate cancer was predominantly right side and indirect type with statistic significance compared to hernias without previous radical prostatectomy.
Purpose:The five-year survival rates of patients with stage III colorectal cancer have been reported widely ranging from 22 to 69 percent. Hence, reliable substaging is important for the management of stage III colorectal cancer patients. Therefore, we tried to assess the substages and investigate the possibility of other discriminating numbers for nodal substaging.
Methods:The 381 patients with node-positive colorectal cancer who had undergone surgery, were retrospectively categorized by the number of positive nodes. The patients were grouped in five ways, and each grouping was divided into two subgroups according to the number of positive nodes. The subgroups of each grouping were as follows; in LN1 group, N1=1, N2>1; in LN2 group, N1=2, N2>2; in LN3 group, N1=3, N2>3; in LN4 group, N1=4, N2>4; in LN5 group, N1=5, N2>5. We compared the survival rate of each groups. Results: Node-positive patients had a five-year survival rate of 55.2 percent. The statistical differences between the N1 and N2 subgroups of each grouping were as follows: LN1 group (P=0.0128), LN2 group (P=0.0052), LN3 group (P=0.6268), LN4 group (P=0.1480), and LN5 group (P=0.6875). Conclusion: There were significant differences in the five-year survival rates between N1 and N2 in the LN1 group and LN2 group, but there were no differences between N1 and N2 in the other groupings. These data raise the possibility that a novel N1∼N2 substaging (N1: 1∼2; N2: >2) is superior to the current N1∼N2 substaging (N1: 1∼3; N2: >3). (J Korean Surg Soc 2010;78:171-176)
