However, postoperative outcomes based on surgical subspecialty have not been well established. This study aimed to compare surgical outcomes of laparoscopic appendectomy across different surgical subspecialties using risk-adjusted cumulative summation (RA-CUSUM) analysis.Methods: A retrospective analysis was conducted on 631 patients undergoing laparoscopic appendectomy between July 2020 and December 2022. Surgeons were categorized into gastrointestinal (GI) or non-GI groups and senior or young groups. Surgical failure was defined as operation time exceeding the mean plus 2 standard deviations, presence of postoperative complications, or readmission within 30 days after surgery. RA-CUSUM analysis was employed to evaluate surgical failure within each group.Results: The GI group performed more partial cecectomies (P = 0.017) and had longer operation times (P = 0.019) than the non-GI group. The senior group exhibited shorter operation time (P < 0.001), reduced length of stay (P = 0.011), and a higher complication rate (P < 0.001) than the young group. RA-CUSUM analysis indicated a decrease in surgical failure as accumulation progressed in both senior and young groups, as well as in the GI and non-GI groups.Conclusion: Outcomes of laparoscopic appendectomy varied by subspecialty and length of experience. However, each surgeon showed trends of decreasing surgical failure over time. These results suggest that the surgeon's subspecialty minimally affects the outcomes of laparoscopic appendectomy, reflecting its fundamental nature within general surgery.","PeriodicalId":8071,"journal":{"name":"Annals of Surgical Treatment and Research","volume":"109 3","pages":"207-214"},"PeriodicalIF":1.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12457793/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TACE's impact on survival and prognostic factors, including microvascular invasion (MVI) and satellite nodules (SNs), was analyzed.Results: The preoperative TACE group (n = 33) had a lower incidence of MVI (P = 0.009) and higher postoperative morbidity (P = 0.001), particularly pleural effusion (P = 0.004) and Clavien-Dindo class III-IV complications (P = 0.033), compared with the upfront hepatectomy group (n = 402).

Local regional therapy for intrahepatic recurrences and surgical resection for extrahepatic recurrences were associated with better OS. MVI, SN, and hepatic vein tumor thrombosis were identified as significant risk factors for poorer RFS and OS. In patients without SN, preoperative TACE improved RFS (P = 0.039) but not OS.Conclusion: Preoperative TACE for huge HCC was associated with reduced MVI but did not improve RFS and OS.

This study aimed to determine whether the expression of glycolytic enzymes is associated with aggressiveness in the presence or absence of chronic lymphocytic thyroiditis (CLT).Methods: The expression of hexokinase 2, lactate dehydrogenase A (LDHA), pyruvate kinase isoform M2 (PKM2), glucose transporter 1 (GLUT1), and monocarboxylate transporter 4 (MCT4) was examined in 233 papillary thyroid carcinoma (PTC) specimens by immunohistochemistry. We evaluated whether the expression of these glycolytic enzymes correlates with lymph node metastasis, extrathyroidal extension (ETE), and recurrence rate, both with and without CLT. In addition, we analyzed the correlation between glycolytic enzyme messenger RNA expression and risk factors in PTC using The Cancer Genome Atlas.Results: All glycolytic enzymes and transporter proteins were overexpressed in PTC compared with normal tissue. PKM2 expression was most highly correlated with the other glycolytic enzymes. High PKM2 expression was significantly linked to increased recurrence risk in patients without CLT (hazard ratio, 1.76; 95% confidence interval, 1.01-3.06; P = 0.046), but this association was not observed in those with CLT.Conclusion: Overexpression of LDHA, PKM2, GLUT1, and MCT4 is associated with PTC. CLT is significantly associated with an increased incidence of gross ETE and, paradoxically, with a reduced recurrence rate in PTC. LDHA expression was lower in the presence of CLT, whereas PKM2 remained consistently linked to a higher recurrence rate in its absence. Among the evaluated glycolytic enzymes, PKM2 may serve as a biomarker for recurrence in PTC.","PeriodicalId":8071,"journal":{"name":"Annals of Surgical Treatment and Research","volume":"109 3","pages":"169-184"},"PeriodicalIF":1.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12457791/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Turkish doctors experience excessive patient overload, contributing to high stress and feelings of overwork. They also showed lower job satisfaction than in Korea. The common reasons for the low preference for general surgery residencies include intense training, excessive workload, and high risk in both countries.Conclusion: This study identified the key challenges in medical and surgical training in Korea and Türkiye. In Korea, shortages can be addressed by reforms in general surgery residency, the development of a balanced residency selection system, and the provision of work opportunities for non-Korean professionals.
