Objective To summarize the experience of emergency coronary artery bypass grafting （CABG） after failed percutaneous coronary intervention. Methods From January 1998 to December 2002, 9 patients underwent emergency CABG after failed percutaneous coronary intervention. The indications of emergency CABG were coronary artery dissection （5 cases）or perforation （2 cases） and acute arterial occlusion （2 cases）. The time averaged 2 hours from onset of ischernia to revascularization. The CABG was performed under off-pump bypass in 3 cases and under CPB in 6 cases. The mean graft number was 3. Results There were no hospital death. The mean follow-up was 17 months. No death and angina occurred. The function of New York Heart Association class Ⅰ-Ⅱ were in 8 patients, class Ⅲ in 1 patient. Conclusion Emergency CABG is an effective management for failed percutaneous coronary intervention if the indication is right.
ObjectiveTo evaluate the role of surgical resection on synchronous multiple pulmonary nodules identified difficultly in clinics.MethodsThe clinical data of 97 patients with synchronous multiple pulmonary nodules who received surgical resection between 2012 and 2019 in Hunan Cancer Hospital were retrospectively analyzed. There were 72 males and 25 females, aged 58.1±9.0 years. Among these patients, there were 78 patients with ipsilateral and 19 patients with bilateral pulmonary nodules. Clinicopathological parameters between main nodules and secondary nodules were evaluated. Perioperative morbidity was also assessed.ResultsThe operation was successfully completed on all patients for the ipsilateral and bilateral lesions. Totally, 71.1% of mian lesions was mostly removed by lobectomy, and the completion rate of video-assisted thoracoscopic surgery (VATS) was 69.1% (67/97); 80.4% of secondary lesions were mostly removed by wedge resection, and the completion rate of VATS was 71.1% (69/97). The incidence of grade 3 or higher complications after unilateral or bilateral surgery was 12.8% and 5.3%, respectively. Postoperative pathology confirmed that the main lesions were malignant in 65 patients (67.0%), mainly adenocarcinoma (63.1%), of which 43.1% were in the stage Ⅰ; 32 patients were benign, mainly tuberculoma (56.3%). There were 29 patients of malignant secondary lesions, 67 benign, and 1 both benign and malignant; the pathological agreement rate of primary and secondary lesions was 54.6% (lung cancer metastases in the lung and all the benign). When the primary lesion was malignant with its diameters of <3 cm, 3-<5 cm, 5-7 cm, >7 cm, the metastatic rate of secondary lesions was 42.5%, 15.8%, 20.0%, 0, respectively. When the primary lesion was malignant with lymph node metastasis, the probability of the secondary lesion being a metastatic tumor was higher than that without lymph node metastasis (46.7% vs. 30.0%, P>0.05). When the primary lesion was malignant and the primary and secondary lesions were located in the same lobe, the secondary lesions were more likely to metastasize (54.5%), while when they were located on different lobes on the same side or different sides, the secondary lesions were more likely to be benign (58.1%, 72.7%), and the possibility of metastasis was small ( 32.6%, 9.1%). When the primary lesion was benign and clinical differential diagnosis was difficult, the secondary lesion was benign.ConclusionFor synchronous multiple pulmonary nodules, the diameter of the primary lesion is large, the metastatic rate of secondary lesions tends to decrease. In ipsilateral synchronous multiple pulmonary nodules, especially with node metastasis, the risk of metastatic nodule increases. Bilateral surgical resection does not significantly increase the perioperative morbidity.
Objective To study the effectiveness of substitute valve at the popliteal vein in treatment of deep venous valve insufficiency of lower extremities. Methods From January 1996 to August 2002, 27 patients were diagnosed having deep venous valve insufficiency of lower extremities by color Doppler and radiography with an average disease course of 17.4 years.All 27 patients had varicose vein, 25 pain, 22 swelling,25 pigmentation in ankle area and 19 chronic ulcerations.Two cases had been treated with great saphenous vein ligation and striping.Averagevein pressure in resting position was (11.00±0.73)kPa,and the ambulatory venous pressure was (9.14±0.68)kPa.All patients were treated with substitute valve at the popliteal vein,and great saphenous vein ligation and stripping, some were treated with subfascial endoscopic perforating veins ablation. Results The average ambulatory venous pressure after operation was (5.94±0.82)kPa,were significantly different from that before operation(P＜0.01). The curative results were satisfactory,and all symptom and physical sign disappeared.After a mean follow-up period of2-6 years,21 cases had satifactory results. Conclusion Substitute valve at the popliteal vein have the value of widespread application.
ObjectiveTo evaluate the clinical experiences and treatment effectiveness of chronic venous insufficiency with venous ulcer in lower limb. MethodsSeventy-eight patients (88 limbs) suffering lower limb chronic venous insufficiency with venous ulcer from May 2004 to April 2011 in this hospital were analyzed retrospectively. All the patients had undergone high ligation for great saphenous vein plus endovenous laser treatment plus subfascial endoscopic perforator vein surgery (SEPS). ResultsPostoperative complications included 3 cases of subfascial haematoma; 2 cases of pneumohypoderma; 3 cases of numbness in anterior tibial and ankle areas. All the ulcers healed between 4 to 6 weeks. Follow up period was between 6 months to 5 years. There was only one recurrence due to residual varicose from ankle area. The mean operation time was 20 min (15－30 min) in SEPS, the average blood loss was 2 ml (1－5 ml), and the mean duration of postoperative hospitalization was 5 d (2－8 d). ConclusionsSEPS is a first treatment choice for CVI with venous ulcer. It has less invasiveness, lower chances for bleeding, shorter operation time, quicker recovery, and fewer complications.
The technique of laparoscopic radical right hemicolectomy is becoming mature, but there are still controversies on some key steps, including the extent of lymph node dissection, the scope of bowel resection, the choice of surgical access and anastomosis. The new function-preserving surgery and natural-orifice transluminal endoscopic surgery (NOTES) have further enhanced the minimally invasive nature of surgery. The author’s have reviewed the latest domestic and international literature, combined with the experience of the author’s center, and elaborated on the current focus issues of laparoscopic radical surgery for right-sided colon cancer.
Objective\ To investigate the clinical significance of measuring central venous pressure in patients after cardiac surgery.\ Methods\ Twenty four patients in postoperative cardiac surgery were randomly chosen, and investigated under three fettles:(1) The patients were sent into intensive care unit on mechanical ventilation; (2) They were all conscious and on mechanical ventilation 8 hours after operation; (3) 24 hours after operation, the patients were conscious with normal breathing.
Objective To compare the difference of effect while using homograft pericardium patch and Gore- tex patch in staged repair of tetralogy of Fallot（TOF） to enlarge the right ventricular outflow tract （RVOT）. Methods Twenty-eight patients with TOF who underwent the staged complete repair were divided into 2 groups according to the date of surgery. Gore-rex group, 13 cases, their RVOT were enlarged with Gore-tex patches. Cryopreserved homograft pericardium patch group, 15 cases, their RVOT were enlarged with cryopreserved homograft pericardium patches. Clinical results and follow-up results were compared. Results There were 1 operative death in Gore-tex patch group （7. 7%）, and 1 early postoperative death in cryopreserved homograft pericardium patch group （6. 7%）. Hemostasia time, the pericardial cavity drainage volume in cryopreserved homograft pericardium patch group were less than those in Gore-tex patch group （P〈0. 01）. All patients were followed-up for 0.8-4.5years. The residual obstruction rate at RVOT level in Gore-tex patch group was higher than that in cryopreserved homograft pericardium patch group by echocardiography （P〈0.01）. No calcification shadow was found on the chest X-ray. Conclusion Homograft pericardium is the tissue with high density and intensity, its elasticity and compliance are good. Using homograft pericardium patch may be helpful to decrease the residual obstruction of RVOT after operation. It can be adapted as a repairing material in heart surgery.
ObjectiveTo evaluate the safety and necessity of recurrent laryngeal lymph node resection by comparing the complications and prognosis of patients with recurrent laryngeal nerve injury receiving different recurrent laryngeal lymph node resections.MethodsWe reviewed the clinical data of 153 patients with stage T1N0M0 esophageal squamous cell carcinoma who underwent radical esophageal cancer surgery at the Department of Thoracic Surgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from June 2014 to May 2016. Among them, 125 were male and 28 were female, at an average age of 62 years. All patients underwent bilateral recurrent laryngeal nodes sampling. They were divided into 3 groups according to the dissection situation: patients with only one recurrent laryngeal lymph node resection on both sides during the operation were treated as a sampling group (n=49); patients with only one recurrent laryngeal lymph node resection on one side and more than one recurrent laryngeal lymph nodes resection on the other side were treated as a unilateral dissection group (n=49); patients with more than one recurrent laryngeal lymph nodes resection on both sides were treated as a bilateral dissection group (n=55). Follow-up was performed to compare the prognostic differences among the three groups. Seven days after the operation, the vocal cords of the patients were examined with an electronic laryngoscope and classified using the Clavien-Dindo system. The differences in complications related to recurrent laryngeal nerve injury among the three groups were compared.ResultsThe 5-year overall survival (OS) rate of the patients in the sampling group, unilateral dissection group and bilateral dissection group was 66.8%, 88.5%, 93.8%, respectively. There was statistical difference between the sampling group and the unilateral dissection group or the bilateral dissection group (P<0.05), and no statistical difference between the unilateral dissection group and the bilateral dissection group (P>0.05). The incidence of complications among the three groups was not statistically different (P>0.05).ConclusionFor patients with esophageal squamous cell carcinoma of stage T1N0M0, the lymph nodes of the bilateral recurrent laryngeal nerves should be removed during the operation as many as possible, which will help improve the 5-year survival rate of the patients.
Patients with brain metastases are more prone to developing life-threatening neurological symptoms. Initial therapies include surgery, whole brain radiotherapy (WBRT), and stereotactic radiotherapy. With the progress of stereotactic radiotherapy, the indication of stereotactic radiosurgery (SRS) is gradually expanding, and the indications for surgery and WBRT gradually narrowed. The existing studies have shown that SRS can significantly benefit patients who are <50 years old with single brain metastasis, but the specific scope of the application with SRS is still controversial, and a large number of the phase Ⅲ randomized multicenter trials designed around the controversies are also developing. This review summarizes the results of clinical research and came to the conclusion. Firstly, postoperative adjuvant SRS in the treatment of brain metastases is superior to postoperative adjuvant WBRT. Secondly, using SRS in the elderly patients with multiple brain metastases are safe and effective. Thirdly, the use of targeted therapy in patients with brain metastases thereby delaying SRS may lead to poor prognosis. The focus of future research include selection of optimal timing for adjuvant targeted therapy after SRS and the appropriate patient population, as well as prevention of recurrence and metastasis after lacal treatment.
ObjectiveTo systematically review the safety of propofol versus sevoflurane for pediatric surgery. MethodsEMbase, PubMed, The Cochrane Library, CSCD, CNKI, WanFang Data were searched to collect randomized controlled trials (RCTs) about propofol versus sevoflurane for pediatric surgery from inception to January 2015. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then metaanalysis was performed by using RevMan 5.3 software. ResultsFifteen RCTs involving 1 065 children were included finally. Meta-analysis results showed that, compared with the sevoflurane group, the propofol group could reduce the incidence of emergence agitation (OR=0.23, 95%CI 0.16 to 0.34, P<0.000 01) and the incidence of postoperative vomiting (OR=0.32, 95%CI 0.20 to 0.51, P<0.000 01). There were no significant differences between the two groups in extubation time (MD=0.98, 95%CI -0.26 to 2.21, P=0.12), eye-opening time (MD=3.32, 95%CI -2.65 to 9.29, P=0.28) and postoperative analgesic requirements (OR=0.60, 95%CI 0.30 to 1.23, P=0.16). ConclusionIn reducing the incidence of emergence agitation and postoperative vomiting, propofol is superior to sevoflurane, so propofol is safer than sevoflurane for children's surgery.
