Objective To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.
甲状腺可发生多种疾病，治疗方法各异，其中，适宜外科治疗者主要是甲状腺肿瘤，尤其是恶性肿瘤，甲状腺功能亢进症虽然有些也采用外科治疗，但并非该病的唯一治疗方法。甲状腺肿瘤外科治疗所采用的术式及病例选择等，至今国内、外仍存在一些不同见解。现就甲状腺肿瘤的外科治疗现状进行重点讨论，并就今后发展略抒己见。
Objective\ To analyze the experiences of emergent or urgent coronary artery bypass grafting(CABG) for patients with acute myocardial infarction(AMI). Methods\ From May, 1996 through December, 1999, 9 patients with AMI underwent emergent CABG including eight males and one female, with mean age 61 years, and year range 44 70. The localization of the AMI was anterior in 4 and inferior in 5. The interval between the onset of AMI and CABG was within 24 hours in 7 cases, 10 days in 1 case and 14 days in 1 case....
Objective To investigate the diagnosis and treatment of congenital choledochal cysts(CCC) in children. MethodsThe manifestation, auxiliary examination, mode of operation and effect of 42 patients with CCC in children from Jan., 1980 to June, 1999 were analyzed retrospectively.Results The patients with the triad of jaundice, an abdominal mass, and pain was 38.1% among the 42 patients. B-ultrasonic diagnosis was made with a correct diagnostic rate of 95.2%. The effective rate of internal drainage was significantly lower than that of resection of the cyst(χ2=19.36, P＜0.001) while the reoperation rate and incidence of carcinoma of internal drainage were higher than those of resection of the cyst(χ2=11.59, P＜0.001 and χ2=4.97, P＜0.05). Conclusion B-ultrasonic diagnosis is recommended as the first examination method. Internal drainage should be abandoned. Resection of the cyst with Roux-Y hepaticojejunostomy is recommended as the treatment of choice on extrahepatic cholangiectasis. Liver transplantation is a reasonable choice to treat the diffuse intrahepatic cholangiectasis.
这个题目，讨论的文章已经很多，现只就几个问题谈一些个人看法。1我国多见的肝胆管结石病有许多特点1.1西方国家极少见原因何在？除感染因素早已确定外，可能有代谢因素和基因等其它问题。1.2病变部位可在肝内各处，较多见于左外叶。可能由于肝内胆管与其下游胆管间的交角较锐，胆流相对迂滞，固形物如结晶颗粒，或异物如蛔虫尸皮等，较易停留。除左肝外，右肝后叶或某些其它部位胆管支也有相似情况。我们还发现畸形发育的右后叶肝管开口于左肝管者，其右后叶中存积结石。1.3胆道蛔虫病仍是主因结石绝大多数是含菌的，这与胆道寄生虫感染有关。除广东、香港等地人们多吃鱼生致中华肝蛭病外，大陆多数地区是由肠蛔虫引致的胆道蛔虫病，都是肠属菌脓性胆管炎。我们还发现，人蛔虫与猪蛔虫不但形态无区别，它们的组织液成分也无区别，故可能交叉感染。我国各地特别是农村几乎家家养猪，这给预防带来很大困难。1.4胆管炎很难净化结石中含菌，有残石即不断感染。结石清除后，管壁的炎性反应伴腺体中残留的细菌将长期存在，以大肠杆菌为主，据文献报道可持续半年以上，很难清除。1.5病灶长期持续慢性炎症与急性发作反复交替，管壁增厚，管腔因结石存在而扩张，管口则常狭窄。受害区的肝组织逐渐萎缩，纤维化，成为一个包括结石、病变胆管和肝组织为一体的病灶。未病的邻近胆管和肝组织常为正常。病灶可能多数，甚至全肝多处分散存在。病灶较常位于肝内亚段胆管，可能的解释是蛔虫上入肝内时，纂到最细处，不能退出，死于其中。其后虫尸腐烂断落，大部可随胆汁流出，而在亚段中的虫尸未被排出者，日后便形成病灶。
Fifty three patients with acute necrotizing pancreatitis were performed operation, treated surgically, including incision of the pancreatic capsule to release the pancreatic presure, removal of necrotic tissue, and placement of drainage tube around pancreas. Twenty two patients (41.5%) developed postoperative peripancreatic abscess. The average hospitalized days (83.3±25.1 days) of the patients with peripancreatic abscess was longer than those without (22.7±14.7 days) peripancreatic abscess (Ｐ＜0.01). Six cases of 28 (21.4%) patients who had localized or scattered pancreatic necrosis developed peripancreatic abscess, 16 cases of 25 (64.0%) patients who had subtotal or total pancreatic necrosis developed peripancreatic abscess which showed significant difference between two groups (Ｐ＜0.01). Among 21 patients in whom 2 to 4 doublelumened tubes for negative presure drainage were placed,5 cases (23.8%) had peripancreatic abscess but 32 patients with only one tube placed, 17 patients (53.1%) had peripancreatic abscess, the difference between two groups were significant (Ｐ＜0.05). At least 6 patients whose drainage tubes worked badly produced postoperative peripancreatic abscess. These results indicate that the peripancreatic abscess is closely related with the severity of the disease, surgical treatment, and proper postoperative care of the drainage tubes.
From 1987 to 1993, 12 cases of primary gastric malignant lymphoma (PGML) were hospitalized. The incidence of PGML was 1.9% of gastric malignancies during the same period. There were 5 cases in stage Ⅰ, 4 in stage Ⅱ, 1 in stage Ⅲ, and 2 in stage Ⅳ. The preoperative diagnosis of PGML was difficult because the incidence of PGML is low, the symptoms are nonspecific, and the radiologic and fibrogastroscopic character were very similar to those of gastric carcinoma and peptic ulcer disease. The surgical treatment of PGML is disccused.
