Purpose Hungry bone syndrome after parathyroidectomy is an important clinical problem in patients on maintenance hemodialysis. We examined the effect of an enhanced recovery after surgery (ERAS) program on the incidence of hungry bone syndrome after parathyroidectomy in this population. Methods This single-institution, retrospective study analyzed 108 patients on hemodialysis who underwent parathyroidectomy for secondary hyperparathyroidism. Patients were classified into the pre-ERAS (n = 52) and post-ERAS (n = 56) groups. The ERAS program identified high-risk patients and enforced aggressive measures to normalize calcium levels following parathyroidectomy. Results There was no significant difference in age, sex, body weight, presenting symptoms, preoperative calcium and alkaline phosphatase levels, postoperative intact parathyroid levels, postoperative calcium levels at 1 and 24 hours after parathyroidectomy, and 30-day readmission rates between the groups. The post-ERAS group had significantly higher levels of postoperative calcium at 48 and 72 hours after parathyroidectomy, but a lower incidence of hungry bone syndrome and shorter postoperative length of stay. Patients with hungry bone syndrome had higher preoperative levels of alkaline phosphatase and intact parathyroid, longer postoperative length of stay, and were less likely to have been part of the ERAS program. High preoperative alkaline phosphatase levels and absence of the ERAS program were independent risk factors for hungry bone syndrome after parathyroidectomy. Conclusion The ERAS program reduced the incidence of hungry bone syndrome and shortened the postoperative length of stay in patients on maintenance hemodialysis who underwent parathyroidectomy for secondary hyperparathyroidism.

Background Secondary hyperparathyroidism (SHPT) remains a common complication in many patients on maintenance hemodialysis. Kidney Disease Improve Global Outcomes (KDIGO) 2017 guidelines suggest that parathyroidectomy (PTX) should be performed in severe SHPT patients with chronic kidney disease stage 3a-stage 5D. In the present study, we observed the efficacy of ultrasonic scalpel for PTX in SHPT patients on maintenance hemodialysis. Methods A total of 74 patients on maintenance hemodialysis who underwent PTX (34 with traditional electrocautery and 40 with an ultrasonic scalpel) were observed between August 2020 and August 2021 at Xiangyang Central Hospital (Hubei University of Arts and Science). Baseline demographic and clinic characteristics were collected pre- and post-PTX. Moreover, the postoperative complications and operation time were assessed between the two groups. Results The univariate analysis showed that there was no statistical significance in weight, dialysis duration, serum potassium, serum calcium, serum magnesium, alkaline phosphate, triglyceride, and intact parathyroid hormone (iPTH) before and after PTX between the two groups (P > 0.05). The operation time in the ultrasonic scalpel group was significantly decreased compared with the traditional electrocautery group (P < 0.05). Compared with the traditional electrocautery group, the drainage amount was significantly reduced in the ultrasonic scalpel group, and the number of days with drain and postoperative hospital stay were also remarkably decreased (P < 0.05). Conclusions The use of ultrasonic scalpel significantly reduced the operation time and postoperative hospital stay in patients on maintenance hemodialysis undergoing PTX.
