Abstract： Objective To compare the influence of different doses of low molecular weight heparin on blood coagulation system of patients who have received thoracic surgery. Methods Eightytwo patients (with lung cancer, esophageal cancer, thymoma, pleural endotheliomas or other diseases) who were treated in Tongji Hospital of Huazhong University of Science and Technology from January 2009 to March 2010 were divided into three groups, based on the time of hospitalization. In the control group, there were 24 patients including 10 females and 14 males with an average age of 43.5±21.3 years. No low molecular weight heparin was given after operation. There were 32 patients in group I, including 14 females and 18 males, with an average age of 45.2±18.6 years. An amount of 0.2 ml (2 125 U) low molecular weight heparin was subcutaneously injected daily during the first 7 days after operation. In group Ⅱ, there were 26 patients including 11 females and 15 males with an average age of 43.8±20.1 years. An amount of 0.4 ml (4 250 U)low molecular weight heparin was subcutaneously injected daily during the first 7 days after operation. The differences of preoperative and postoperative coagulation factors including prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), D dimer (D-D), platelet count (PLT) and anti-Ⅹa activity were observed. Results The preoperative average values of PT, APTT, Fib, D-D, PLT of all the three groups were in the normal range and showed no significant difference (Pgt;0.05). For all three groups, after operation, PT prolonged, APTT shortened, the amount of Fib, D-D increased, PLT reduced on the 3rd day and then increased on the 7th day and anti-Ⅹa activity increased, all of which showed a significant difference from preoperative values (Plt;0.05). The amount of Fib in group Ⅱ was significantly lower than that in group Ⅰ after operation (the 5th day after operation: 4.7±2.5 g/L vs. 7.0±3.3 g/L, Plt;0.05); the amount of D-D in group Ⅱ was significantly lower than that in the control group (the 5th day after operation: 891.3±891.3 μg/L vs. 1 583.2±984.7 μg/L, Plt;0.05) and group Ⅰ (the 5th day after operation: 891.3±891.3 μg/L vs. 1 452.6±1 052.9 μg/L,Plt;0.05); and the anti-Ⅹa activity of group Ⅱ was significantly higher than that in group Ⅰ (the 5th day after operation: 0.54±0.05 U/ml vs. 0.29±0.04 U/ml, Plt;0.05). Conclusion In a certain weight range, fixeddose (4 250 U) of low molecular weight heparin is able to improve postoperative hypercoagulable state and avoid the occurrence of venous thromboembolism without increasing risk of complications like bleeding.
Abstract: Objective To explore the protection of pulmonary function by shortening the thoracic opening time inesophagectomy of esophageal carcinoma. Methods A retrospective review of the postoperative pulmonary function of 54 patients with upper esophageal cancer undergoing esophagectomy with triple incisions in Tongji Hospital from January 2007 to April 2010 was conducted. The patients were divided into two groups. Twentyeight patients including 25 males and 3 females aged at 58.9±8.2 years were in in the classic procedure group, accepting classical esophagectomy with triple incision approach. Among them, there were 26 patients with squamous carcinoma and 2 with adenocarcinoma. Twentysix patients including 22 males and 4 females aged at 54.7±9.4 years were in the improved procedure group, accepting improved esophagectomy with triple incision approach. Among them, 25 patients had squamous carcinoma and 1 had adenocarcinoma. We analyzed the difference of the thoracic opening time, onelung ventilation time during the operation, arterial oxygen pressure (PaO2), arterial carbon dioxide differential pressure(PaCO2), pulse oximeter saturation (SpO2), postoperative mechanical ventilation time, intensive care unit (ICU) stay time, postoperative oxygen support days, postoperative inhospital days, and the incidence of pulmonary infection and respiratory failure between the two groups. Results There was a statistical difference between the two groups in thoracic opening time (4.7±1.2 hours versus 2.6±0.8 hours, t=7.51, Plt;0.05) and onelung ventilation time (3.7±15 hours versus 23±0.8 hours, t=4.23, Plt;0.05). The PaO2 and SpO2 on the 1st day and the 3rd day after operation were significantly lower than those before operation in both the classic procedure group (on the 1st day after [CM(159mm]operation, PaO2: F=516.03, Plt;0.05; SpO2: F=129.63, Plt;0.05; on the 3rdday after operation, PaO2: F=213.99, Plt;005; SpO2: F=61.84, Plt;0.05) and the improved procedure group (on the 1st day after operation, PaO2: F=423.56, Plt;0.05; SpO2: F=184.24, Plt;0.05; on the 3st day after operation, PaO2: F=136.78, Plt;0.05). On the 1st day after operation, PaO2 and SpO2 in the improved procedure group were significantly higher than those in the classic procedure group (F=36.20, Plt;0.05; F=93.42, Plt;0.05), while PaCO2 in the improved procedure group was significantly lower than that in the classic procedure group (F=155.49, Plt;0.05). On the 3rd day after operation, PaO2 in the improved procedure group was significantly higher than that in the classic procedure group (F=29.23, Plt;0.05). The postoperative mechanical ventilation time and ICU stay time in the improved procedure group were significantly shorter than those in the classic procedure group (t=3.81, P=0.00; t=4.65, Plt;0.05). Conclusion Improved esophagectomy of carcinoma with triple incision approach can significantly shorten the thoracic opening time and onelung ventilation time during operation, which plays a good role in protecting pulmonary function and lowering the incidence of pulmonary complications.
ObjectiveTo investigate the feasibility and clinical effect of controlled hypotension in 3 cm single-port video-assisted thoracoscopic surgery (VATS) for the lymph node group 7 dissection in the left lung resection. MethodsWe retrospectively analyzed the clinical data of 37 patients with lung cancer who underwent 3 cm single-port VATS from May 2015 to August 2015 in Tongji Hospital, and systolic blood pressure of 12 patients (7 males, 5 females, average age of 58.3 years, range 42-69 years) was controlled between 80-90 mm Hg by nitroglycerin or sodium nitroprusside while the pressure of 25 patients (14 males, 11 females, average age of 57.7 years, range 43-68 years) was not controlled when receiving lymph node group 7 dissection. ResultsControlled hypotension in lymphadenectomy achieved satisfactory results. The lymphadenectomy time of 12 patients with controlled hypotension (18.5±4.3 min on average, range 15.6-25.3 min) was shorter than that of 25 patients without controlled hypotension (24.3±5.1 min on average, range 18.2-29.8 min); the difference was statistically significant (P<0.05). ConclusionControlled hypotension is a simple and feasible method that increases the operating space, and reduces the difficulty of cleaning lymph nodes and the risk of bleeding.
Objective To investigate the effect of modular disscection of mediastinal lymphadenectomy in uniportal video-assisted thoracoscopic surgery (uniportal-VATS) for lung cancer radical resection and assess its safety and feasibility. Methods Data of 311 patients (171 males and 140 females, a mean age of 59.4±5.1 years) with non-small cell lung cancer (NSCLC) who received modular dissection of mediastinal lymphadenectomy in uniportal-VATS or three portal VATS (3P-VATS group) during March to December 2015 were retrospectively analyzed. There were 208 patients (110 males and 98 females, a mean age of 59.2±5.3 years) in the uniportal-VATS group and 103 patients (61 males and 42 femals, a mean age of 59.7±5.1 years) in the 3P-VATS group. The effects of lymph nodes (LNs) dissection and postoperative clinical data were compared between the two groups, especially for N2 LNs dissection. Results There were no perioperative death in two groups. The overall number of dissected stations and LNs in the uniportal-VATS group (7.3±1.0, 17.5±3.0) were similar with those in the 3P-VATS group (7.2±1.0, 17.7±2.7, P=0.208, P=0.596). The dissected stations (uniportal-VATS: 4.3±0.7, 3P-VATS: 4.3±0.6) and number (uniportal-VATS: 8.6±1.1, 3P-VATS: 8.5±1.1) of N2 LNs were both similar between the two groups (P=0.850, P=0.587). The chest tube duration and postoperative hospital stay of uniportal-VATS group (4.4±1.3 d and 9.2±0.9 d) were much shorter than those of 3P-VATS group (5.0±1.3 d and 9.8±2.0 d, both P<0.001). No significant difference was found in morbidity rate between the two groups (P>0.05). Conclusion Modular dissection of mediastinal lymphadenectomy could meet the requirment of radical resection and it is a safe and valid method which could be used during uniportal-VATS for radical resection of lung cancer.
Objective To investigate the feasibility and clinical outcomes of minimally invasive sternal depression by autologous force for the correction of pectus carinatum. Methods Between October 2011 and September 2015, 22 pectus carinatum patients underwent minimally invasive surgical correction of pectus carinatum in Tongji Hospital. Clinical data of 22 patients were retrospectively analyzed. There were 19 males and 3 females with a mean age of 12.00±2.87 years, ranging from 6 to 15 years. Among them, 17 patients were symmetric malformation, and the others were asymmetric. Preoperative chest CT scan was performed on 14 patients. Haller index was 1.65-2.23 (1.97±0.15). All the patients underwent the minimally invasive surgical correction of pectus carinatum with a NUSS bar via sternal depression by autologous force. Results All the operations were completed successfully. The mean operation time was 55-120 (83.73±16.62) min and blood loss volume was 10-50 (28.18±11.63) ml. The mean postoperative hospital stay was 3-6 (4.23±1.17) d. Postoperative complications included wound infection in 2 patients, minor pneumothorax in 3 patients, who were cured by conservative treatment. One patient suffering postoperative hydropneumothorax received drainage. All the patients were followed up for 6-48 months after discharge and very satisfied with the chest appearance following surgery. No patient complained of persistent pain. There was no displacement of the bar or the stabilizers. Nine patients underwent the removal of the NUSS bar without pectus carinatum recurrence. Conclusion Minimally invasive sternal depression by autologous force simplifies the procedure of correction of pectus carinatum with reliable and satisfactory outcomes.
