Comparison of oblique versus hockey-stick surgical incision for kidney transplantation.
The hockey-stick surgical incision is becoming more popular than the oblique incision for kidney transplantations. Both incisions are convenient and comfortable. Both have some drawbacks, such as muscle denervation for the former, or section of lateral muscles for the latter. In this retrospective study, we compared these incisions with regard to the incidence of long-term complications, such as postincisional hernia, relaxation of the abdominal wall, and a poor cosmetic result. One hundred patients (50 of each type) were evaluated at an average of 4.5 years after transplantation (3 months-15 years). Occurrence of incisional hernia was 16% in the former (8 cases) versus 4% in the latter (2 cases: X(2) = 4; P < .05). A major relaxation of the abdominal wall was found in 24% of the former (12 cases) versus 8% of the latter (4 cases) (X(2) = 4.76; P < .05). These complications were not correlated with age, sex, weight, side of transplant, or immunosuppressive drugs. In the former patients with hockey-stick incisions, the overall cosmetic results were poor, because in most cases the incision had been prolonged upward, above the transverse umbilical line, even as high as the costal arch. In 20% of the former patients with hockey-stick incisions, the scar had widened, particularly in the upper vertical branch of the J incision. We conclude that the final outcome of the oblique surgical incision was better than the hockey-stick incision because of the lower incidence of hernia and abdominal wall relaxation and the more favorable cosmetic results.
