 We performed a prospective study to elucidate the efficacy and problems associated with the closed suction drainage system following posterior microendoscopic surgery. Drain placement was evaluated by plain radiography. Discomfort and pain around the puncture site for the drain tube, low back pain, and leg pain were assessed on a visual analogue scale (VAS) before and after drain removal. Inappropriate placement of the suction drain was observed in 12% of the patients in the microendscopic discectomy (MED) group, but not in any of the patients in the open surgery group. There was significant improvement in the VAS scores for wound pain, back discomfort, back pain, and leg pain after surgery. Placement of the suction drain caused some minor complications. Statistical analysis showed that the material from which the drain was made was unrelated to the occurrence of the minor postoperative complications.
