Open surgery is an important part of vascular surgery. For vascular surgery diseases not suitable for endovascular therapy, adjuvant methods of endovascular therapy and the ultimate means of treatment after failure, vascular graft infection, open vascular trauma, various tumors involving blood vessels, vascular reconstruction and complications of organ transplantation, iatrogenic vascular injury, and so on, open surgical procedures still need to be provided for treatment and development. This paper lists the important role that open surgery plays in supporting the treatment of vascular related diseases and the development of the discipline in surgery and internal medicine, and emphasizes that open surgery is still a necessary quality for vascular surgeons, the basis and important guarantee for the development of the discipline, and the guarantee for the timely and effective treatment of various complex and difficult vascular surgical diseases.
Objective To summarize selection of therapeutic method for isolated iliac aneurysms and analyze its advantages and disadvantages. Method The clinical data of 21 patients with isolated iliac aneurysms from January 2006 to January 2017 in this hospital were analyzed retrospectively. Results Four patients were treated with an open surgery such as the unilateral iliac prosthetic graft interposition, aorto-biiliac or aorto-bifemoral arterial bypass graft, ligation of internal iliac artery, etc.. Seventeen patients were treated with an endovascular treatment such as the unilateral iliac stent-grafts, bifurcated aortic stent-grafts, or coil embolization alone, etc.. One patient with ruptured isolated iliac aneurysms died during the endovascular repair, and the rest patients were cured after the operation. The average operative time was 2.83 h and 1.58 h, the average hospital stay was 17.5 d and 7.7 d respectively for the patients with the open surgery and the endovascular treatment. Except 1 case of type Ⅰ and 1 case of type Ⅱ endoleaks were found in the patients with the endovascular treatment, no complications such as the ureteral and intestinal injuries, the gluteal muscle claudication, and the sigmoid ischemia were found in all the patients. Seventeen cases were followed-up. The following-up rate was 85%. The following-up time was 1–60 months with an average of 22 months. During the following-up period, the grafts and stent grafts were patent and the aneurysm sac diameter was unchanged. The abscess of the iliac fossa occurred in 1 patient with systemic lupus erythematosus and improved after the symptomatic treatment. Two patients died of other diseases during the following-up period, and the rest had no obvious clinical symptoms. Conclusions Preliminary results of limited cases in this study show that endovascular repair and open surgery in treatment of appropriately selected patients with isolated iliac artery aneurysms is safe and effective. But in special situation, technical controllability of open surgery might be better than endovascular repair, treatment should be selected according to patient’s general condition and anatomy of aneurysm.
ObjectivesTo systematically review the efficacy and safety of ultrasound-guided percutaneous microwave ablation versus traditional open surgical operation in the treatment of benign thyroid nodules.MethodsPubMed, The Cochrane Library, EMbase, CBM, CNKI and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on ultrasound-guided percutaneous microwave ablation versus traditional open surgery for benign thyroid nodules from inception to June 30th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was then performed by RevMan 5.3 software.ResultsA total of 38 RCTs involving 4 078 patients were included. The results of meta-analysis showed that: ultrasound-guided percutaneous microwave ablation might be more effective than traditional open surgery for the treatment of benign thyroid nodules (RR=1.09, 95% CI 1.00 to 1.19, P=0.04), and compared with traditional open surgery, ultrasound-guided percutaneous microwave ablation reduced the rate of postoperative complication (RR=0.26, 95%CI 0.21 to 0.31, P<0.000 01), shortened postoperative hospital stay (MD=–3.60, 95%CI –4.04 to –3.15, P<0.000 01) and the time consumed in operation (MD=–48.79, 95%CI –54.16 to –43.41, P<0.000 01), and reduced operative blood loss (MD=–22.02, 95%CI–23.87 to –20.17, P<0.000 01). Meanwhile, microwave ablation reduced the elevated levels of serum IL-6 content (MD=–10.34, 95%CI –10.70 to –9.97, P<0.000 01), serum CRP content (MD=–9.70, 95%CI –10.95 to –8.44, P<0.000 01) and serum TNF-α content (MD=–7.94, 95%CI –9.00 to –6.88, P<0.000 01).ConclusionsCurrent evidence shows that ultrasound-guided percutaneous microwave ablation may improve clinical efficacy and can reduce postoperative complications, bleeding volume, operation time, hospitalization days and postoperative inflammatory reaction. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo compare the differences of clinical effects between the bilateral endoscopic breast reconstruction and the open breast reconstruction. MethodsThe clinical data of 28 female patients who underwent bilateral breast graft reconstruction in the Department of Breast Surgery of West China Hospital from January 2017 to January 2021 were analyzed retrospectively. The patients were divided into two groups: an endoscopic group (n=12, aged 41.3±8.9 years) and an open group (n=16, aged 41.6±8.8 years). The clinical data of the two groups of patients were compared. Results There was no significant difference in demographic and oncological data between the two groups (P>0.05). There was a significant difference in the implants between the two groups (P=0.008). The operation time (298.2±108.6 min vs. 326.5±95.8 min, P=0.480) and anesthesia time (373.4±91.2 min vs. 400.3±97.1 min, P=0.463) were not significantly different. The total complications (P=0.035) and major complications (P=0.024) in the open group were more than those in the endoscopic group. For the comparison of breast satisfaction, psychosocial well-being and sexual well-being, the scores at six months and one year after surgery were higher in the endoscopic group than those in the open group (P<0.05). ConclusionThe endoscopic reconstruction is safe and effective, with high satisfaction rates regarding breast reconstruction and quality of life, and is superior to conventional open surgery.
Objective To compare microendoscopic discectomy (MED) with open discectomy (OD) for degenerative lumbar spinal stenosis in terms of cl inical outcomes, and provide experience and therapeutic evidence for cl inical appl ication.Methods From May 2002 to October 2007, 215 patients with lumbar spinal stenosis were randomized into two groups, and underwent either MED or OD. In group A, 105 patients underwent MED, including 56 males and 49 females aged 34 to 83 years old (average 45 years old); the duration of the disease ranged from 9 months to 26 years (average 50 months); the spinal stenosis involved one segment in 76 cases, two segments in 27 cases, and three segments in 2 cases. In group B, 110 patients received OD, including 57 males and 53 females aged 35 to 85 years old (average 47 years old); the duration of the disease ranged from 8 months to 25 years (average 48 months); the spinal stenosis involved one segment in 78 cases, two segments in 29 cases, and three segments in 3 cases. No significant difference was evident between two groups in terms of the general information(P gt; 0.05). Results Operation was successfully performed in all cases. Volume of intraoperative blood loss was (82.14 ± 6.18) mL in group A and (149.24 ± 11.17) mL in group B. Length of hospital stay was (7.0 ± 2.1) days in group A and (12.0 ± 2.6) days in group B. Significant difference was noted between two groups in terms of the above parameters (P lt; 0.01). All the wounds healed by first intention. The patients were followed up for 13-54 months (average 27 months) in group A and 12-55 months (average29 months) in group B. Four patients in each group suffered from spinal dural rupture during operation and recovered after corresponding treatment. Three patients in group B had lumbar instabil ity 3 years after operation and recovered using lumbar interbody fusion combined with general spine system internal fixation. No such compl ications as wrong orientation, nerve root injury, cauda equina injury and infection occurred in each group, and radiology exam showed no relapse. Therapeutic effect was evaluated by Nakai standard, 52 cases in group A were graded as excellent, 45 as good, 7 as fair, 1 as poor, and the excellent and good rate was 92.4%; 53 cases in group B were graded as excellent, 48 as good, 8 as fair, 1 as poor, and the excellent and good rate was 91.8%; there was no significant difference between two groups (P gt; 0.05). Conclusion Two methods have the similar therapeutic effect, but MED el iminates the shortcomings of traditional OD, so it is one of ideal minimally invasive operative approaches for degenerative lumbar spinal stenosis.
ObjectiveTo summary the standard treatment for early gastric cancer. MethodsThe current early gastric cancer treatment guidelines around the world were analyzed and the standardized treatment patterns for early gastric cancer were concluded. ResultsThe accurate preoperative evaluation for early gastric cancer is the basis of standardized treatment which can be divided into staging evaluation and histological evaluation.The staging evaluation is focused on the gastric wall invasion and lymph node involvement of the tumor while the histologic evaluation emphasize the histological type and grading of the tumor.According to the precise evaluation for early gastric cancer, endoscopic surgery, laparoscopic surgery, open surgery, and multimodal therapy can be applied individually to the patients.Different treatment methods have their indications, but the indications of the therapies in different guidelines are suggested with slight differences. ConclusionIn clinical practice, the choice of treatment should be made with comprehensive consideration of diagnosis and individual characteristics of patients to achieve the most benefit on prognosis.
ObjectiveTo evaluate the effectiveness of robot-guided percutaneous fixation and decompression via small incision in treatment of advanced thoracolumbar metastases. Methods A clinical data of 57 patients with advanced thoracolumbar metastases admitted between June 2017 and January 2021 and met the selection criteria was retrospectively analyzed. Among them, 26 cases were treated with robot-guided percutaneous fixation and decompression via small incision (robot-guided group) and 31 cases with traditional open surgery (traditional group). There was no significant difference in gender, age, body mass index, lesion segment, primary tumor site, and preoperative Tokuhashi score, Tomita score, Spinal Instability Neoplastic Score (SINS), visual analogue scale (VAS) score, Oswestry disability index (ODI), Karnofsky score, and Frankel grading between groups (P>0.05). The operation time, hospital stays, hospital expenses, intraoperative blood loss, postoperative drainage volume, duration of intensive care unit (ICU) stay, blood transfusion, complications, and survival time were compared. The pedicle screw placement accuracy was evaluated according to the Gertzbein-Robbins grading by CT within 4 days after operation. The pain, function, and quality of life were evaluated by VAS score, ODI, Karnofsky score, and Frankel grading. Results During operation, 257 and 316 screws were implanted in the robot-guided group and the traditional group, respectively; and there was no significant difference in pedicle screw placement accuracy between groups (P>0.05). Compared with the traditional group, the operation time, hospital stays, duration of ICU stay were significantly shorter, and intraoperative blood loss and postoperative drainage volume were significantly lesser in the robot-guided group (P<0.05). There was no significant difference in hospital expenses, blood transfusion rate, and complications between groups (P>0.05). All patients were followed up 8-32 months (mean, 14 months). There was no significant difference in VAS scores between groups at 7 days after operation (P>0.05), but the robot-guided group was superior to the traditional group at 1 and 3 months after operation (P<0.05). The postoperative ODI change was significantly better in the robot-guided group than in the traditional group (P<0.05), and there was no significant difference in the postoperative Karnofsky score change and Frankel grading change when compared to the traditional group (P>0.05). Median overall survival time was 13 months [95%CI (10.858, 15.142) months] in the robot-guided group and 15 months [95%CI (13.349, 16.651) months] in the traditional group, with no significant difference between groups (χ2=0.561, P=0.454) . Conclusion Compared with traditional open surgery, the robot-guided percutaneous fixation and decompression via small incision can reduce operation time, hospital stays, intraoperative blood loss, blood transfusion, and complications in treatment of advanced thoracolumbar metastases.
ObjectiveTo compare the surgical data, safety, cosmetic outcomes, and quality of life of patients underwent single axillary incision endoscopic nipple-sparing mastectomy and immediate breast reconstruction with endoscopic harvesting of latissimus dorsi muscle flap (abbreviation as the “endoscopic group”) and traditional open surgery of latissimus dorsi muscle flap harvesting for breast reconstruction after mastectomy (abbreviation as the “open group”). MethodsThe patients were collected, who underwent latissimus dorsi breast reconstruction at the West China Hospital of Sichuan University and the Fourth People’s Hospital of Sichuan Province from January 2021 to June 2024 from a prospective maintenance database, and then were assigned into an endoscopic group and open group according to the surgical method. Their basic information, information relevant operation, postoperative complications, and patient reported outcomes (BREAST-Q scale) score were compared between the two groups. ResultsA total of 73 patients were enrolled, including 23 patients in the endoscopic group and 50 patients in the open group. There were no statistically significant differences in the age, body mass index, breast sagging, tumor location, tumor N stage, pathological type, adjuvant therapy, etc. between the patients of two groups, except for a higher proportion of T4 stage patients in the open group as compared with the endoscopic group (P＜0.001). A longer size of latissimus dorsi muscle flap was harvested in the endoscopic group as compared with the open group (P=0.002). There were no statistically significant differences in the total surgical complications, major complications, minor complications, and implant-related complications between the patients of two groups (P>0.05). The most common complication in the patients of both groups was back seroma, 21.7% (5/23) in the endoscopic group and 22.0% (11/50) in the open group. The total length of incisions in the endoscopic group was significantly shorter than that in the open group (P<0.001), and the points of the breast satisfaction (P=0.045), back satisfaction (P<0.001), and sexual well-being (P=0.028) of the patients in the endoscopic group were significantly higher than those in the open group. The major complications did not happen in the endoscopic group, but happened in 2 cases in the open group (1 patient due to ischemic necrosis of the latissimus dorsi muscle and 1 patient due to breast infection resulting in implant removal). During the follow-up period, 3 (6.0%) patients had distant metastasis (all were lung metastasis) in the open group, and there was no local or regional recurrence, distant metastasis, and specific death of breast cancer in the endoscopic group. ConclusionsThe results of this study suggest that, for patients who have skin invasion but who desire breast reconstruction or have failed by prosthetic breast reconstruction (such as skin flap necrosis), traditional open surgery of latissimusdorsi flap harvesting for breast reconstruction is worth choosing. However, for breast cancer patients who do not need additional skin breast reconstruction, endoscopic latissimus dorsi breast reconstruction has greater advantages in cosmetic effect, and it is safe and effective.
