Abstract:

Introduction: Gastroparesis presents a significant challenge in pregnancy, affecting maternal and foetal health. This paper examines the safety and efficacy of Gastric Electrical Stimulation (GES) as a therapeutic modality in pregnant patients with gastroparesis.
Materials & Methods: A retrospective analysis was conducted on pregnant patients with in-situ GES identified from our gastroparesis patient database. We evaluated the safety and efficacy of GES during pregnancy, focusing on Quality of Life (QoL) improvements and symptom control. Key metrics included QoL SF36 scores, and the severity of nausea, vomiting, pain, satiety, and bloating. Hospital stay lengths, admission frequency, and the need for feeding support were also assessed both pre- and post-operatively
Results: The study included twelve pregnant women with in-situ GES. The median age at surgery was 29 years (Interquartile Range [IQR]: 26-31 years), with 58% of the patients having diabetes-induced gastroparesis. Robotic GES insertion was performed in 75% of cases. Postoperatively, significant improvements were observed in nausea score (reduced from 4 to 1), vomiting score (from 4 to 0), pain score (from 4 to 1), satiety score (from 4 to 0), and bloating score (from 4 to 0). SF36 scores improved significantly, increasing from a median pre-operative score of 261 (IQR: 178-65) to 1,783 (IQR: 765-3,527, p<0.001). Additionally, 58% of patients transitioned from assisted to independent feeding.
Conclusion: Gastric Electrical Stimulation appears to be a safe and effective treatment modality for gastroparesis in pregnant patients, significantly improving symptoms and QoL. Further extensive research is warranted to validate these findings and explore the broader implications of GES in the management of pregnancy-associated gastroparesis.
