RESUMO
Objective:To summarize the experience and the clinical data of patients with primary hyperparathyroidism undergoing endoscopic parathyroidectomy.Methods:A total of 24 patients who underwent endoscopic parathyroidectomy for primary hyperparathyroidism in Peking Union Medical College Hospital during Feb. 2021 to May. 2022 were concluded in this study (20 cases of parathyroidectomy via axillary approach and 4 cases of parathyroidectomy via thoracic and breast approach) . The operation time, postoperative drainage, length of stay, level of parathyroid hormone and serum calcium of those patients were collected. Postoperative complications and recurrence of hyperparathyroidism were also observed.Results:The postoperative levels of serum parathyroid hormone and serum calcium were significantly reduced (over 50%) compared with preoperative level ( P<0.05) . The average operation time was (96±22) min (64-157 min) . The mean postoperative drainage volume was (47±16) ml on day 1, (46±11) ml on day 2, and (30±9) ml on day 3, respectively. The average length of postoperative hospital stay was (2.8±1.1) days (2-6 days) . In one case of parathyroidectomy via axillary approach, the operation was converted to open surgery because of the low position of lesion. Other cases completed endoscopic surgery and obtained satisfactory cosmetic results. There were no postoperative complications such as bleeding, permanent hoarseness, coughing while drinking water, or surgical site infection. The mean follow-up time was (7.4±4.2) months (1-16 months) . There was no obvious discomfort and no recurrence during follow-up. Conclusion:Endoscopic parathyroidectomy is safe and effective in the treatment of primary hyperparathyroidism, which can be used as a surgical option for patients with cosmetic requirements.
RESUMO
<p><b>BACKGROUND</b>Pancreatic cancer is a lethal disease that is often diagnosed at an advanced stage. There is a lack of information to predict the prognosis of pancreatic cancer. Krüppel-like factor (KLF) 8 has been found to be deregulated in multiple cancers, and its high expression was correlated with poor prognosis. However, so far, no information was reported about the expression of KLF8 in pancreatic cancer. In the present study, we investigated, possibly for the first time, the expression of KLF8 in pancreatic cancer samples and analyzed its correlation with clinical parameters and overall survival (OS) rate.</p><p><b>METHODS</b>We used immunohistochemical staining to detect KLF8 in 68 samples from patients who underwent surgery and its correlation with the clinicopathological characteristics. We used Kaplan-Meier curve to analyze the relationship between KLF8 expression and the OS time. Univariate analysis was performed in addition to multivariate hazard models with clinicopathological features to assess KLF8 as an independent prognostic factor.</p><p><b>RESULTS</b>KLF8 was present in the cytoplasm of pancreatic cancer cells and 52.9% of the 68 cases had positive expression. KLF8 expression was not associated with sex, age, tumor location, lymph node stage, and metastasis stage, but was associated with tumor stage (P = 0.04). Kaplan-Meier method demonstrated that patients with negative expression of KLF8 had a better prognosis. In univariate and multivariate models, KLF8 was a significant predictor of OS in pancreatic cancer.</p><p><b>CONCLUSION</b>Our results revealed that KLF8 may be a potential prognostic factor for pancreatic cancer.</p>
