Obesity is a major public health issue that affects a significant proportion of patients with end-stage renal disease (ESRD). In patients undergoing peritoneal dialysis (PD), obesity complicates treatment by increasing the risk of mechanical complications and infections and reducing the effectiveness of peritoneal exchanges. Furthermore, obesity limits access to kidney transplantation, making weight loss a crucial goal. Bariatric surgery is emerging as an effective strategy for improving metabolic condition and promoting placement on a transplant waiting list. Sleeve gastrectomy (SG) is now the preferred technique for helping obese patients on ESRD lose weight, particularly due to its favorable safety profile, reduced operating time, and absence of intestinal bypass, thus limiting the risk of deficiencies. The available data, although limited to case series and isolated reports, suggest that SG can be performed in PD patients either with early resumption of PD or after a temporary transition to hemodialysis depending on clinical status. Optimized protocols include a gradual resumption of PD at low volumes, minimizing the risk of leakage or infection. Bariatric surgery therefore appears feasible and generally safe in PD patients, provided that a rigorous multidisciplinary assessment and close nutritional monitoring are carried out to prevent malnutrition and sarcopenia. It is a relevant therapeutic option for improving access to kidney transplantation and optimizing the prognosis of obese patients with ESRD. This article was written following a presentation at the Société Francophone de Néphrologie, Dialyse et Transplantation 2025 on the feasibility of bariatric surgery in PD.
