Minimally invasive step-up approach is both safe and effective, but sometimes requires multiple access sites.METHODS: A 62-year-old woman was admitted with diabetic ketoacidosis, and initial computed tomography(CT) revealed no evidence of acute pancreatitis. She was clinically improved with insulin therapy, fl uid administration, and electrolyte replacement. However, on the 14 th day of admission, she developed a high-grade fever, and CT demonstrated evidence of acute necrotizing pancreatitis with a large collection of peripancreatic fl uid. Percutaneous transgastric drainage was performed and a 14 French gauge(Fr) pigtail catheter was placed 1 week later, which drained copious pus. Because of persistent high-grade fever and poor clinical improvement, multiple 8 and 10 Fr pigtail catheters were placed via the initial drainage route, allowing the safe and effective drainage of the extensive necrotic tissue that was occupying the bilateral anterior pararenal space.RESULTS: After drainage, the patient recovered well and the last catheter was removed on day 123 of admission.CONCLUSIONS: Multiple percutaneous drainage requires both careful judgment and specialist skills. The perforation of the colon and small bowel as well as the injury of the kidney and major vessels can occur. The current technique appears to be safe and minimally invasive compared with other drainage methods in patients with extended, infected necrotic pancreatic pseudocysts.展开更多

The traditional surgical approaches for attempting a complete excision of these lesions frequently involve big incisions and tissue dissection with high risk of postop instability and cerebrospinal fluid leakage. Also, there is a risk of neurological worsening, sometimes irreversible. Methods: We present our experience in a patient series with spinal canal tumors and describe the surgical approach with minimally invasive techniques (MIS). All of them were performed by the Neurosurgery team of the Hospital Universitario San Ignacio during the period of 2011-2016. Results: We reviewed forty patients with spinal canal tumors surgically treated with MIS techniques. 15 patients (37.5%) had Meningioma diagnosis (complete resection in 11 (73.3%), subtotal in 3 (20%) and biopsy in one patient), 10 patients (25%) with Schwannomas reached complete resection in 70% and subtotal in 30%. 5 patients had spinal cord metastasis, with complete resection in 4 patients (80%) and subtotal in 1 (20%). Other included ependymoma, astrocytoma, and miscellaneous. No patient has had cerebrospinal fluid leakage and no postoperative fusion has been required. Conclusions: The minimally invasive approach allowed complete tumors removal in a high number of patients and good postoperative results. These findings are similar and in some cases, better than the reported with traditional techniques. This MIS technique provides encouraging results. It requires a wide learning curve and a high degree of surgical experience.展开更多

Surgical management of lumbar degenerative disease has historically been approached by way of open surgical procedures aimed at decompressing and/or stabilizing the lumbar spine. Advances in technology andsurgical instrumentation have led to minimally invasive surgical techniques being developed and increasingly used in the treatment of lumbar degenerative disease. Compared to the traditional open spine surgery, minimally invasive techniques require smaller incisions and decrease approach-related morbidity by avoiding muscle crush injury by self-retaining retractors, preventing the disruption of tendon attachment sites of important muscles at the spinous processes, using known anatomic neurovascular and muscle planes, and minimizing collateral soft-tissue injury by limiting the width of the surgical corridor. The theoretical benefits of minimally invasive surgery over traditional open surgery include reduced blood loss, decreased postoperative pain and narcotics use, shorter hospital length of stay, faster recover and quicker return to work and normal activity. This paper describes the different minimally invasive techniques that are currently available for the treatment of degenerative disease of the lumbar spine.展开更多

Although valve repair is preferred over replacement whenever possible, valve replacement may be required in certain patients. In situations where the mitral or tricuspid anatomy are unfavorable and exposure is difficult, seating a prosthetic valve in the annulus through a right mini-thoracotomy approach may be difficult, compared to conventional sternotomy approach. This is complicated by limited tactile feedback in the minimally invasive approach. Herein, we describe several simple maneuvers that facilitate proper prosthetic valve seating and visualization of the posterior annulus during minimally invasive valve operations via right mini-thoracotomy.展开更多

Intraventricular hematoma has always been a difficult problem for clinical treatment. Although minimally invasive endoscopic hematoma evacuation is widely used to treat this disease, the technique still has room for improvement. Equipment for the intra-neuroendoscopic technique（INET） consists of two of our patented inventions： a transparent sheath（Patent No. ZL 200820046232.0） and a hematoma aspirator（Patent No. ZL 201520248717.8）. This study explored the safety and efficacy of INET by comparing it with extraventricular drainage in combination with urokinase thrombolytic therapy. This trial recruited 65 patients with severe intraventricular hemorrhage, including 35（19 men and 16 women, aged 53.2 ± 8.7 years） in the INET group and 30（17 men and 13 women, aged 51.5 ± 7.9 years） in the control group（extraventricular drainage plus urokinase thrombolytic therapy）. Our results showed that compared with the control group, the INET group exhibited lower intraventricular hemorrhage volumes, shorter intensive care-unit monitoring and ventricular drainage-tube placement times, and fewer incidences of intracranial infection, secondary bleeding, and mortality. Thus, the prognosis of survivors had improved remarkably. These findings indicate that INET is a safe and efficient new method for treating severe intraventricular hematoma.

The aim of current analysis was to apply an explicitly defined sub-group analysis to confirm whether this hypothesis is true. Methods A computerized literature search was applied to find any data concerning MIS or mini-incision THAs. A multistage screening was then performed to identify randomized studies fulfilling the inclusive criteria for the analysis. The data were extracted, and sub-group analyses of MIS or mini-incision surgery for different kinds of outcomes were carried out. The P（sub） value for difference between MIS sub-group and mini-incision sub-group was also calculated. Results Eleven studies that fulfilling the inclusion criteria were included, with 472 cases in the study group （MIS or mini-incision） and 492 cases in the conventional group. The overall analysis showed the study group would achieve less surgical duration （P=0.037）, intraoperative blood （P 〈0.001） and incision length （P 〈0.001） than conventional group. The difference between sub-groups showed, the MIS would achieve shorter incision length （P（sub） 〈0.05） and bigger cup abduction angle （P（sub） 〈0.05）, and cause more blood loss （P （sub） 〈0.05） than mini-incision technique. Other indexes were comparable between the two sub-groups. Conclusions Though further high quality studies are still needed, the result of current analysis offered an initial conclusion that MIS THA failed to achieve a better clinical outcome than mini-incision technique. The exact definition of MIS still needs to be improved.展开更多

文摘BACKGROUND: In approximately 20% of patients, necrotizing pancreatitis is complicated with severe acute pancreatitis, with high morbidity and mortality rates. Minimally invasive step-up approach is both safe and effective, but sometimes requires multiple access sites.METHODS: A 62-year-old woman was admitted with diabetic ketoacidosis, and initial computed tomography(CT) revealed no evidence of acute pancreatitis. She was clinically improved with insulin therapy, fl uid administration, and electrolyte replacement. However, on the 14 th day of admission, she developed a high-grade fever, and CT demonstrated evidence of acute necrotizing pancreatitis with a large collection of peripancreatic fl uid. Percutaneous transgastric drainage was performed and a 14 French gauge(Fr) pigtail catheter was placed 1 week later, which drained copious pus. Because of persistent high-grade fever and poor clinical improvement, multiple 8 and 10 Fr pigtail catheters were placed via the initial drainage route, allowing the safe and effective drainage of the extensive necrotic tissue that was occupying the bilateral anterior pararenal space.RESULTS: After drainage, the patient recovered well and the last catheter was removed on day 123 of admission.CONCLUSIONS: Multiple percutaneous drainage requires both careful judgment and specialist skills. The perforation of the colon and small bowel as well as the injury of the kidney and major vessels can occur. The current technique appears to be safe and minimally invasive compared with other drainage methods in patients with extended, infected necrotic pancreatic pseudocysts.

文摘AIM To perform a systematic review and meta-analysis on minimally vs conventional invasive techniques for harvesting grafts for living donor liver transplantation.METHODS Pub Med,Web of Science,EMBASE,and the Cochrane Library were searched comprehensively for studies comparing MILDH with conventional living donor hepatectomy(CLDH).Intraoperative and postoperative outcomes(operative time,estimated blood loss,postoperative liver function,length of hospital stay,analgesia use,complications,and survival rate)were analyzed in donors and recipients.Articles were included if they:(1)compared the outcomes of MILDH and CLDH;and(2)reported at least some of the above outcomes.RESULTS Of 937 articles identified,13,containing 1592 patients,met our inclusion criteria and were included in the meta-analysis.For donors,operative time[weighted mean difference(WMD)=20.68,95%CI:-6.25-47.60, =0.13]and blood loss(WMD=-32.61,95%CI:-80.44-5.21, =0.18)were comparable in the two groups.In contrast,analgesia use(WMD=-7.79,9 5%C I:-1 4.0 6-1.8 7, =0.0 1),posto pera tive complications[odds ratio(OR)=0.62,95%CI:0.44-0.89, =0.009],and length of hospital stay(W M D):-1.2 5,9 5%C I:-2.3 5-0.1 4, =0.0 3)significantly favored MILDH.No differences were observed in recipient outcomes,including postoperative complications(OR=0.93,95%CI:0.66-1.31, =0.68)and survival rate(HR=0.96,95%CI:0.27-3.47, =0.95).Funnel plot and statistical methods showed a low probability of publication bias.CONCLUSION MILDH is safe,effective,and feasible for living donor liver resection with fewer donor postoperative complications,reduced length of hospital stay and analgesia requirement than CLDH.
文摘目的探讨行通道辅助微创修复系统缝合术修复急性闭合性跟腱断裂的临床疗效。方法将2017年3月至2021年9月收入成都体育学院附属体育医院的90例急性闭合性跟腱断裂患者进行回顾性分析。根据术前医患沟通结果,分为微创组(45例)和开放组(45例)。微创组采用微创跟腱断裂通道吻合器吻合术,开放组采用切开改良Kessler断端吻合术。比较两组患者的手术时间、切口长度、并发症;分别比较两组患者术后1、6、12个月的疼痛视觉模拟评分(visual analogue scale,VAS)、美国骨科足踝协会后足与踝评分(American Orthopaedic Foot and Ankle Society,AOFAS)和足跖屈-背伸活动度(range of motion,ROM)。结果微创组及开放组患者均获12~24个月的随访,平均为(18.4±5.6)个月。微创组的手术时间较开放组手术时间明显少,微创组手术切口长度较开放组手术切口长度明显短,两组比较差异有统计学意义(P<0.05)。微创组术中、术后并发症明显低于开放组,两组比较差异有统计学意义(P<0.05),微创组及开放组患者术后1个月的VAS评分,差异有统计学意义(P<0.05);术后6、12个月的VAS评分,差异无统计学意义(P>0.05)。两组患者术后1、6个月的AOFAS评分,差异有统计学意义(P<0.05);术后12个月AOFAS评分比及术后6、12个月的足跖屈-背伸活动度比较,差异无统计学意义(P>0.05)。结论采用微创跟腱断裂通道吻合器修复急性闭合性跟腱断裂,具有微创、并发症少、早期康复等优势。
