RESUMO
Background: Bariatric surgery is a surgical procedure for patients with extreme obesity. Enhanced Recovery after Surgery (ERAS) is a method that provides special peri- and post-operation care. Here, we aimed to compare the effects of ERAS and standard recovery cares. Materials and Methods: This is a randomized clinical trial that was performed in 2020-2021 in Isfahan on 108 candidates for mini gastric bypass. Patients were then randomly divided into two equal groups receiving ERAS and standard recovery protocols. Patients were examined and visited after one month regarding the average number of hospitalization days, the average days required to return to normal activity or work, occurrence of pulmonary thromboemboli (PTE) and the rate of readmission. Results: Patients that received ERAS had significantly lower frequencies of nausea and vomiting (P = 0.032). Patients that received ERAS had significantly lower hospitalization duration (P < 0.001) compared to controls. No other significant differences were observed between two groups regarding surgery complication, re-admission rate and occurrence of PTE (P > 0.99 for all). Conclusion: Patients that received ERAS protocol after gastric bypass had significantly lower hospitalization duration and lower incidence of nausea and vomiting. They also had similar post-operative outcomes compared to the standard protocol.
RESUMO
BACKGROUND: Some studies have shown that a preoperative high concentration of thyroglobulin (Tg) in wash out of fine-needle aspiration cytology of cervical lymph nodes mandate therapeutic lymph node dissection. However, there is disagreement about the minimum concentration of Tg which could have diagnostic value. Hence, according to our literature review, this study is the first one which designed to do intraoperatively. Therefore, this study was conducted and aimed to determine the clinical diagnostic value of Tg lymph nodes in the diagnosis of metastatic thyroid cancer. METHODS: In a cross-sectional study, 65 patients with papillary thyroid carcinoma (PTC) who were thyroidectomy candidates were chosen and during surgery, before the removal of lymph nodes in the neck, fine-needle sampling was performed and the level of Tg in the samples, nature of the sample sent for biopsy and Tg levels in affected and unaffected lymph nodes were determined. RESULTS: The mean levels of washout Tg in malignant and nonmalignant lymph nodes were 622.1 ± 66.2 and 1.38 ± 0.43 ng/ml, respectively, and the difference between the two groups was significant (P < 0.001). The Tg cut-off point for the detection of lymph node metastases was 0.7 ng/dl, and according to it, Tg washout sensitivity was 93.8%, specificity of 92.4%, false positives 7.76%, false negatives 6.3%, positive predictive value was 92.3%, and negative predictive value was 93.8% and accuracy was 93.1%. CONCLUSION: Based on the results, Tg level of cervical lymph nodes in patients with PTC is a suitable criterion for the diagnosis of lymph node which can be determined through fine-needle biopsy. Therefore, it is suggested that in patients with suspicion of lymph nodes involvement during surgery, fine-needle biopsy and determination of the Tg level performed.
