Introduction and importance Primary adrenal leiomyosarcoma (PAL) is an extremely rare neoplasm that usually arises from the smooth muscle cells of the adrenal or adjacent vascular structures. The tumor is asymptomatic until it grows up and develops a mass effect in the retroperitoneal region. Although there are about 50 reported valid cases, surgical intervention is mandatory in the majority of patients. Case presentation Herein, we report the case of a 32-year-old healthy woman with a chief complaint of vague abdominal pain. After initial clinical and radiological examinations, we found a large retroperitoneal mass located around the right adrenal gland. Due to the patient's pain, a laparotomy was performed, and a large mass was resected with free margins. Immunohistochemical examination was positive for vimentin, smooth muscle actin (SMA), and desmin. Therefore, the diagnosis of PAL was confirmed. Conclusion Although PAL is an uncommon malignancy, its diagnostic and therapeutic approaches are almost straightforward. A computed tomography scan can show the characteristics of the tumor and direct the management. Surgical resection is the mainstay of treatment, and the effects of adjuvant therapies have not been apparent yet.

Introduction Post-operative nausea and vomiting (PONV) is a common problem after sleeve gastrectomy. In recent years, following the increase in the number of such operations, special attention has been paid to preventing PONV. Additionally, several prophylaxis methods have been developed, including enhanced recovery after surgery (ERAS) and preventive antiemetics. Nevertheless, PONV has not been completely eliminated, and the clinicians are trying to reduce the incidence of PONV yet. Methods After successful ERAS implementation, patients were divided into five groups, including control and experimental groups. Metoclopramide (MA), ondansetron (OA), granisetron (GA), and a combination of metoclopramide and ondansetron (MO) were used as antiemetics for each group. The frequency of PONV during the first and second days of admission was recorded using a subjective PONV scale. Results A total of 130 patients were enrolled in this study. The MO group showed a lower incidence of PONV (46.1%) compared to the control group (53.8%) and other groups. Furthermore, the MO group did not require rescue antiemetics, however, one-third of control cases used rescue antiemetics (0 vs. 34%). Conclusion Using the combination of metoclopramide and ondansetron is recommended as the antiemetic regimen for the reduction of PONV after sleeve gastrectomy. This combination is more helpful when implemented alongside ERAS protocols.
