Correct measurement of the posterior wall size of adult male inguinal hernia used for herniorrhaphy / 中国组织工程研究

ABSTRACT

BACKGROUND:The mesh size used for herniorrhaphy mainly depends on clinicians' experience, which is less reliable. OBJECTIVE:To obtain the mesh size by measuring the posterior wall of inguinal hernia in Chinese adult men undergoing Rutkow surgery, and to assess the postoperative effect. METHODS:The posterior wall size of inguinal hernia in 180 Chinese adult male patients undergoing tension-free hernioplasty was measured, and then the optical mesh size was calculated. All patients were equivalently randomized into two groups, followed by subjected to Rutkow surgery according the calculated mesh size (experimental group) or subjective size (control group). Clinical indexes, the incidence of complications and recurrence rate were compared between groups. RESULTS AND CONCLUSION:The distance of pubic tubercle to internal oblique inguinal ligament starting point was (6.03±0.58) cm;the vertical distance of the highest point on the edge of the arcuate to inguinal ligament was (3.02±0.32) cm;therefore, the length of mesh should be larger than (13.04±0.74) cm, and width larger than (5.88±0.52) cm. The time of off-bed, dieting and hospitalization in the experimental group were significantly less than those in the control group (P0.05). The rates of postoperative complication and recurrence in the experimental group were significantly lower than those in the control group (P<0.01). These results suggest that after measuring the posterior wall size of inguinal hernia, the Rutkow used for inguinal hernia repair, obtains desired treatment outcomes with low incidence of complications and recurrence.
