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.
OBJECTIVE: To investigate the therapeutic effect of subfascial endoscopic perforator vein surgery (SEPS) in treatment of varicose of the lower limb. METHODS: From 1999. 11 to 2000. 12, 108 patients with varicose of the lower limb underwent venous surgery and 34 of them were treated by SEPS. There were 16 males and 18 females aged 20-79(averaged 51.4 years). Thirty limbs (26 cases) had open ulcers and the diameter of ulcer was 1.5-12.0 cm. Eleven limbs (8 cases) had severe pigmentation and the skin changes had been presented for 1 month to 15 years. According to the severity of illness, flush saphenofemoral ligation, great saphenous vein stripping, percutaneous continuous venous circum suture, external femoral vein valve repair and SEPS were performed separately or simultaneously. RESULTS: Active ulcers healed in 19 limbs after 1 month, in 7 limbs after 3 months, and in the other 4 ulcers after skin transplantation. There was no ulcer recurrence during follow-up (ranged 9-22 months). CONCLUSION: SEPS can accelerate the healing of venous ulcers, and it is one of important methods in the treatment of chronic venous insufficiency.
Objective To compare the therapeutic effects between endoscopic thyroidectomy by anterior chest approach and modified Miccoli thyroidectomy. Methods Sixty patients with thyroid goiter were performed endoscopic thyroidectomy by anterior chest approach (endoscopic thyroidectomy by anterior chest approach group, n=30) and modified Miccoli thyroidectomy (modified Miccoli group, n=30) respectively. The operative time, the drainage volume, cosmetic benefit, the postoperative hospitalization time, the expenses of hospitalization and postoperative complications of two groups were compared. Results The operative time and the drainage volume after operation of endoscopic thyoidectomy by anterior chest approach group were significantly more than modified Miccoli group 〔(99.9±23.4) min vs. (74.0±29.6) min; (68.6±8.7) ml vs. (40.9±6.1) ml, respectively〕, Plt;0.05. The cosmetic benefit score of endoscopic thyoidectomy by anterior chest approach group was higher than that of modified Miccoli group 〔(4.7±0.2) points vs. (3.7±0.1) points〕, Plt;0.05. The postoperative hospitalization time and expenses of hospitalization were no significant differences between the two groups 〔(6.5±1.7) d vs. (5.5±0.9) d; (9 328.3±1 107.1) yuan vs. (8 568.2±1 032.3) yuan, respectively〕, Pgt;0.05. One case had transient hoarseness in 2 groups respectively, no other complications happened. Conclusions Modified Miccoli operation is both minimally invasive and cosmetic, but endoscopic thyroidectomy by anterior chest approach has better cosmetic benefit, which can release patients’ psychological trauma. The patients with specific cosmetic demand may choose endoscopic thyroidectomy by anterior chest approach.
The incidence, mortality, and disability rate of spontaneous intracerebral hemorrhage (SICH) are high, and its surgical and medical treatment is still controversial. With the development of micro-neurosurgical technology, minimally invasive surgery (MIS) has made great progress in the treatment of SICH. It can remove intracerebral hematoma in the early stage after SICH and minimize or eliminate secondary brain injury, which is of great significance to reducing the mortality and disability rate. For many years, due to its continuous progress, MIS has been more and more widely used in the treatment of SICH. This article mainly reviews the progress of MIS in SICH and related clinical research at home and abroad, and briefly describes several innovative techniques related to MIS, which aims to promote the exchange of clinical experience in MIS of SICH.
Objective To study the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) and early endoscopic management for acute biliary pancreatitis. Methods Ninety-one patients with acute biliary pancreatitis were divided into ERCP group (46 cases) and control group (45 cases) according to the therapy methods. All patients were given positive conventional treatment, the patients of the ERCP group accepted endoscopic therapy within 48 h after hospitalization. The curative effects of two groups were observed, and the related indexes, such as time of abdominal pain relief, temperature to normal, leukocytes to normal, liver function to normal, average time in hospital, and mortality were compared between two groups. Results Among 46 patients by ERCP diagnosis, there were 27 cases of common duct stone (CDS), 6 cases of cholecystolithiasis, 3 cases of great diverticulum at duodenal papilla side, 4 cases of suppurative cholangitis, 3 cases of stenosis in bile common duct inferior segment and 3 cases of no abnormality. Among 27 cases of CDS, 20 patients had endoscopic sphincterotomy (EST), 4 had duodenal papilla artifistulation, 20 had calculus removed by once basket and aerocyst, and 7 patients with suppurative cholangitis and great stone saccepted EST or macadam after stabilization. The cases of great diverticulum at duodenal papilla side and cases of stenosis in bile common duct inferior segment accepted EST, the cases of suppurative cholangitis accepted endoscopic nasobiliary drainage (ENBD), and all accepted ENBD. The time of abdominal pain relief, temperature to normal, leukocytes to normal, liver function to normal, and the average time in hospital in the ERCP group were significantly shorter than those in the control group (Plt;0.05). The blood amylase to normal time and mortality had no significant differences between two groups (Pgt;0.05). Conclusion The early endoscopic management for patients with acute biliary pancreatitis can clear etiology, reduce the time in hospital and be minimally invasive, safe, and effective.
Objective
To explore the feasibility and effectiveness of spinal pedicle screw internal fixation through endoscope-assisted posterior approach for the treatment of traumatic atlantoaxial instability.
Methods
Between September 2008 and September 2010, 44 patients with traumatic atlantoaxial instability received spinal pedicle screw internal fixation through endoscope-assisted posterior operation (micro-invasive surgical therapy group, n=22) or traditional surgical therapy (control group, n=22). There was no significant difference in gender, age, type of injury, disease duration, and preoperative Japanese Orthopedic Association (JOA) score between 2 groups (P gt; 0.05). The blood loss, operation time, length of the incision, improvement rate of JOA, and graft fusion rates were compared between 2 groups to assess the clinical outcomes.
Results
The blood loss, operation time, and length of the incision in the micro-invasive surgical therapy group were better than those in control group (P lt; 0.05). All incisions were primary healing. Of 88 pedicle screws, 7 pedicle screws penetrated into the interior walls of cervical transverse foramen in the micro-invasive surgical therapy group and 8 in the control group, but there was no syndrome of vertebral artery injury. All patients of the 2 groups were followed up 12 to 37 months (mean, 26 months). Bony fusion was achieved in all cases within 3 to 12 months (mean, 5.3 months). No loosening or breakage of screw occurred. At 6 months to 1 year after operation, the internal fixator was removed in 6 cases and the function of head and neck rotary movement were almost renewed. The JOA score was significantly improved at last follow-up when compared with preoperative score (P lt; 0.05), and no significant difference in JOA score and improvement rate between the 2 groups at last follow-up (P gt; 0.05).
Conclusion
The micro-invasive surgical therapy can acquire the same effectiveness to the traditional surgical therapy in immediate recovery of stability, high graft fusion rate, and less complication. Moreover, it can significantly reduce the operation time, blood loss, and soft tissue injury, so this approach may be an ideal way of internal fixation to treat traumatic atlantoaxial instability.
ObjectiveTo evaluate the safety and efficacy of endoscopic techniques for diagnosis and treatment of breast diseases. MethodsRelated literatures of recent years were reviewed. ResultsA minimally invasive endoscopic technique can be performed through small incisions. This can contribute greatly to reducing postoperative pain, shortening recovery time, and achieving a good cosmetic outcome. Under endoscopy, meticulous dissection and hemostasis can be achieved. Endoscopeassisted subcutaneous mastectomy, immediate mammary reconstruction, sentinel lymph node biopsy and axillary lymph node dissection, for breast cancer can be performed safely. Endoscopic surgery can also be applied for the diagnosis and treatment of benign breast tumor and transaxillary removal of glandular tissue in gynecomastia. In addition, fiberoptic ductoscopy can be used to diagnose patients with nipple discharge. Endoscopic surgery for patients with breast diseases can offer an excellent cosmetic outcome and maintain normal physiologic functions without a noticeable scar. It helps to give the patients confidence and improve the quality of life. ConclusionBreast surgery is a good candidate for endoscopic techniques.
ObjectiveTo analyze and explore the thyroid defunctionalization method for preoperative preparation of hyperthyroidism patients in endoscopic thyroid surgery.
MethodsThe clinical data of 45 cases of hyperthyroidism treated with endoscopic surgery in this hospital from June 2009 to June 2014 were analyzed retrospectively. These patients were divided into study group (n=20) and control group (n=25) according to the preoperative preparation method, the study group was prepared with thyroid defunctionalization method, the control group was prepared with antithyroid drugs and iodine. The intraoperative blood loss, conversion to open surgery, and postoperative complications were compared in these two groups.
ResultsThe intraoperative blood loss and the operation time of the study group were significantly less than those of the control group﹝intraoperative blood loss: (120.32±50.26) mL versus (200.63±60.95) mL, P < 0.05; operation time: (120.43±40.56) min versus (180.76±50.92) min, P < 0.05﹞. There was no case of conversion to open surgery in the study group, there were three cases of conversion to open surgery in the control group. The incidence of postoperative complications of the study group was significantly lower than that of the control group﹝10% (2/20) versus 24% (6/25), P < 0.05﹞.
ConclusionThyroid defunctionalization method is more suitable as compared with the traditional method for the preoperative preparation of hyperthyroidism in endoscopic thyroid surgery.
ObjectiveTo compare the disinfection effect of peracetic acid versus glutaraldehyde in disinfection of flexible endoscope, and provide suggestions for choosing endoscopic disinfectant.MethodsWe searched literatures in PubMed, Embase, Cochrane Central Library, China National Knowledge Infrastructure, Wanfang database and VIP database, with the retrieval time from the establishment of each database to July 2017, screening and comparing the disinfection qualification rate of peroxyacetic acid versus glutaraldehyde in immersion disinfection of flexible endoscope. The number of flexible endoscopies after disinfection was the main effect index, and a fixed effect model analysis was performed.ResultsSix comparative studies were enrolled in this Meta-analysis, with a total of 786 flexible endoscopes. The result of Meta-analysis showed that the qualification rate of disinfection of peracetic acid was higher than that of glutaraldehyde with the same disinfection time [relative risk=1.09, 95% confidence interval (1.06, 1.13), P<0.000 01].ConclusionThe disinfection effect of peroxyacetic acid immersion method is better than that of glutaraldehyde.
ObjectiveTo explore the safety, effectiveness, and cosmetic advantage of endoscopic thyroidectomy for differentiated thyroid cancer in the cT1N0 stage.
MethodsThe clinical data of 148 patients underwent thyroidectomy for the cT1N0 differentiated thyroid cancer in the First Affiliated Hospital of PLA General Hospital and the PLA General Hospital from September 2010 to September 2013 were analyzed retrospectively, including 36 patients by total endoscopic thyroidectomy (TET group), 41 patients by endoscopic-assisted thyroidectomy (EAT group), and 71 patients by open thyroidectomy (OT group). The intraoperative status, early complications, late complications, and cosmetic result were compared among these three groups.
ResultsAll the procedures were accomplished successfully.①In the intraoperative status: The operation time of the TET group was significantly longer than that of the EAT group(P < 0.05)or OT group (P < 0.05), drainage on the first day after operation in the TET group was significantly more than that in the EAT(P < 0.05)or OT group (P < 0.05), the intraoperative bleeding of the TET group or EAT group was significantly less than that of the OT group (P < 0.05), there were no statistical significances in the total number of lymph nodes dissection and number of positive lymph nodes among three groups (P > 0.05).②In the early complications: The postoperative pain score of the TET group was significantly lower than that of the EAT group (P < 0.05)or OT group (P < 0.05), there were no statistical significances in the postoperative bleeding, seroma, infection, transient recurrent laryngeal nerve paralysis, or transient hypoparathyroidism among three groups (P > 0.05).③In the late complications: there was no statistical significance in the perpetual recurrent laryngeal nerve paralysis, perpetual hypoparathyroidism, or thyroid cancer relapse among three groups (P > 0.05).④The best cosmetic result was obtained by the patients underwent TET as compared with the patients underwent EAT(P < 0.05)or OT (P < 0.05).
ConclusionsEndoscopic procedure has the same effectiveness and safety with open procedure for differentiated thyroid cancer in the cT1N0 stage, but endoscopic procedure has a better cosmetic result than that open procedure. Compared with EAT, TET has more advantages in the cosmetic result.
