The aim of this study was to determine short-term outcomes of SPLND in obese patients (pts) with gynaecological cancer in the low-volume cancer center.Methodology The analyses were done on a retrospective consecutive series of 109 obese pts with gynaecological cancer treated from January 2015 to December 2018. All pts underwent different kind of hysterectomy with SPLND. Pts were divided into two groups. The first group consisted of 61 pts with a BMI over 30,0, the second group consisted of 48 pts with a BMI less than 30.Results Postoperative mortality was not in both groups. Morbidity was 26.2±5.6% in the first group and 8.3±4.0% in the second. The duration of the operation was 201.0±14.1 min in the first group and 218.2±16.7 min in the second. Duration of the operation in pts with Class III obesity was 233.3±56.9 min. The duration of the operation after previously performed gynecological operations was 214.0±25.4 min in the first group and 235.0±34.2 min in the second. The number of lymph nodes removed was 21.5±2.1 in the first group and 23.1±2.9 in the second. In pts with Class III obesity, the number of lymph nodes removed was 19.0±3.6, while in pts with Class I obesity - 22.2±3.0. The duration of hospital stay did not differ in pts of the first and second groups generally, but was significantly higher (by 9 days) in pts with Class III obesity.Conclusion Obesity leads to an increase in postoperative morbidity, duration of the operation and an increase in hospital stay in pts underwent different kind of hysterectomy with SPLND.Disclosure Nothing to disclose.
