Contrasting Sleeve Gastrectomy with Lifestyle Modification Therapy in the Treatment of Polycystic Ovary Syndrome.

AIMS
To explore the feasibility of sleeve gastrectomy (SG) as a treatment for polycystic ovary syndrome (PCOS) and its potential to improve clinical efficacy in PCOS patients with symptoms of oligomenorrhea.


PATIENTS AND METHODS
Twenty-four obese patients with PCOS underwent laparoscopic SG. Simultaneously, 24 obese patients with PCOS received lifestyle modification therapy (LMT). Follow-ups were conducted at 3-6 months. Weight loss, menstruation, and improvements in hirsutism and metabolic symptoms were compared.


RESULTS
In the SG group, 20 patients were restored to normal menstrual cycles and ovulation at 3-6 months after surgery. Their average androgen levels decreased significantly following surgery (P=.012). Conversely, only 6 patients in the LMT group were restored to normal menstrual cycles and ovulation after receiving 3 months of treatment. Their average preoperative and postoperative androgen levels showed a nonstatistically significant decrease (P>.05). Compared with the LMT group, the SG group showed more pronounced improvements in menstruation. Additionally, body mass and body mass index were significantly reduced in patients in the SG group 3 months after the surgeries, with maximum weight loss observed at approximately 6 months after surgery. Patients who received LMT showed a gradual weight reduction such that body mass decreased significantly after 3 months (P<. 001). Compared with patients in the LMT group, patients in the SG group showed greater weight loss results (P<.0001).


CONCLUSIONS
In patients with PCOS, SG resulted in more marked weight loss and better improvements in clinical symptoms compared with LMT.
