Longitudinal analysis of retroperitoneoscopic adrenalectomy regarding cosmesis outcomes: comparison of lateral transperitoneal and reduced port laparoscopic adrenalectomy

The aim of this study is to compare patient-reported cosmesis and satisfaction outcomes between lateral retroperitoneoscopic adrenalectomy (LRA), laparoendoscopic single site and reduced port adrenalectomy (LESS/RP-A) and lateral transperitoneal laparoscopic adrenalectomy (LTA). A total of 26, 86 and 50 patients who underwent LRA, LESS/RP-A and LTA were included in the study. All LESS/RP-A cases were performed taking the transumbilical approach. We mailed a questionnaire to all patients 1, 3, 6, 9 and 12 months after operation. Questionnaires inquiring about cosmesis (0: very ugly, 10: very beautiful) on the basis of a visual analogue scale were administered. The mean scores of cosmesis at postoperative months 1, 3, 6, 9 and 12 were 7.11, 7.00, 6.57, 5.25 and 5.46 for the LRA group, 8.43, 8.86, 8.95, 8.46 and 9.09 for the LESS/RP-A group and 7.18, 7.74, 7.58, 7.44 and 8.09 for the LTA group. The difference in cosmesis score between the LRA and LESS/RP-A groups gradually increased after surgery, and the cosmesis score for the LRA group was significantly lower at every postoperative point. The difference in cosmesis score between the LRA and LTA groups gradually increased after surgery, and the cosmesis score for the LRA group was significantly lower at postoperative months 9 (p = 0.015) and 12 (p = 0.002). This study is the first comprehensive longitudinal analysis of patient-reported cosmesis outcomes between LRA, LESS/RP-A and LTA. LRA was the surgical procedure that resulted in lower cosmesis scores when compared with those following the LESS/RP-A and LTA procedures.
