Laser Welding - Suitable for Vascular Anastomosis?
1994
Carotid arteries of 21 piglets were transsected and reanastomosed either by laser welding (Neodym:YAG laser) or by conventional suture anastomosis. Histological specimens of the anastomoses obtained 2 to 32 days after the operation showed less foreign body reaction and intimal hyperplasia after laser welding than after suturing. There was, however, no significant difference when comparing occurrence of thrombosis, patency rate, or growth of the anastomosis in growing animals. Neither our study nor a review of the literature of laser-assisted vascular anastomosis in microvessels and large arteries up to 5 mm diameter could establish a definite clinical application for laser welding in vascul…
Techniques and outcomes of pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension.
2006
Cardiopulmonary function in patients with chronic thromboembolic pulmonary hypertension can almost be normalized by pulmonary endarterectomy. The procedure involves the removal of organized and incorporated fibrous obstructive tissue from the pulmonary arteries during circulatory arrest under deep hypothermia. Mortality rates reported for patients who have undergone pulmonary endarterectomy range from 4 to 24%. The operation is not an embolectomy but a true endarterectomy. After proximal intrapericardial pulmonary artery incision, the correct endarterectomy plane is established and circumferentially followed down to the lobar, segmental, and sometimes subsegmental pulmonary artery branches …
Randomized controlled trial of postoperative exercise rehabilitation program after lumbar spine fusion: study protocol
2012
Abstract Background Lumbar spine fusion (LSF) effectively decreases pain and disability in specific spinal disorders; however, the disability rate following surgery remains high. This, combined with the fact that in Western countries the number of LSF surgeries is increasing rapidly it is important to develop rehabilitation interventions that improve outcomes. Methods/design In the present RCT-study we aim to assess the effectiveness of a combined back-specific and aerobic exercise intervention for patients after LSF surgery. One hundred patients will be randomly allocated to a 12-month exercise intervention arm or a usual care arm. The exercise intervention will start three months after su…
Outcome of Bleb Revision With Autologous Conjunctival Graft Alone or Combined With Donor Scleral Graft for Late-onset Bleb Leakage With Hypotony Afte…
2020
Prcis Treatment of leakage with ocular hypotony after trabeculectomy with mitomycin C (MMC) can be safely achieved through conjunctival patch alone or combined with donor scleral graft in cases of melted underlying sclera. Purpose To report outcomes of 2 surgical approaches for treating ocular hypotony in eyes with blebs with late-onset leakage after standard trabeculectomy with MMC. Methods Thirty consecutive cases with bleb leakage and hypotony underwent bleb revision surgery between 2009 and 2014 by the same surgeon (J.W.) at the Department of Ophthalmology of the Mainz University Medical Center, Germany. In 18 patients, an autologous conjunctival patch graft was applied. In 12 patients,…
Laparoscopic Treatment of Endoscopic Sigmoid Colon Perforation
2006
Perforation of the colon after colonoscopy is a rare but potentially lethal complication. It usually occurs when endoscopy is performed for therapeutic purposes. In these cases the election of the best treatment is difficult and still controversial. Laparoscopy is a new approach for diagnosis and treatment of this condition. We report a case of a patient who was initially treated laparoscopically after a colonoscopic perforation. A postoperative leak was detected and the patient underwent open surgery. Possible therapeutic approaches and a literature review are discussed.
Surgeon volume and hospital volume in endocrine neck surgery: how many procedures are needed for reaching a safety level and acceptable costs? A syst…
2018
The relationship between quality of care and provider's experience is well known in all fields of surgery. Even in thyroidectomies and parathyroidectomies, the emphasis on positive volume-outcome relationships is believed. It led us to an evaluation of volume activity's impact in terms of quality of care. A systematic narrative review was performed. According to the PRISMA criteria, we selected 87 paper and, after the study selection was performed, 22 studies were finally included in this review. All articles included were unanimous in attributing to activity volume of surgeons as well as centers a substantial importance. Some differences in outcomes between these investigated categories ha…
[Current developments and perspectives on the diagnosis and treatment of urinary incontinence and genital prolapse in women].
2012
As a key area of gynaecology, urogynaecology has undergone impressive changes in the past few years. Together with the high prevalence of functional pelvic floor disorders, modern anaesthesia procedures and the introduction of new, innovative minimally invasive operation techniques have led to a dramatic increase in the number of operations for incontinence and prolapses. The increasingly subtle diagnostic options, such as, e. g., 2D and 3D sonography of the pelvic floor provide unambiguous findings and facilitate decision making. Tension-free vaginal slings in retro-pubic, trans-obturator or single-incision techniques show a high success rate with few complications and have almost complete…
Imperative and Elective Indications for Nephron-Sparing Surgery for Renal Tumors: Long-Term Oncological Follow-Up
2010
INTRODUCTION: Nephron-sparing surgery (NSS) is mandatory for patients with renal tumors in both kidneys or in a solitary kidney in order to preserve renal function (imperative indication). NSS has also become the gold standard (elective indication) for small unilateral renal tumors (< 4 cm) with a normal contralateral kidney. We report the oncological long-term follow-up of NSS of our own series and discuss the results of the current literature. PATIENTS AND METHODS: From 1979 until 2006, a total of 851 patients was treated at our institu-tion by NSS. The mean tumor diameter was 3 cm (0.5-11 cm) for elective cases and 4.2 cm (1.2-11 cm) for imperative cases. The median follow-up for electiv…
Pediatric Urinary Diversion: Review and Own Experience
1992
New insights into the diseases of childhood, profound improvements and new developments in surgical techniques as well as the knowledge gained from long-term follow-up have altered the strategies and indications for urinary diversion in childhood. Continent urinary diversion is generally the method of choice. We are able to construct high capacity, low pressure reservoirs to protect the upper urinary tract and achieve continence. Nowadays, there is hardly any indication for permanent cutaneous urinary diversion. Temporary and intermediate cutaneous diversion are used only when serious conditions such as renal function deterioration occur. The possibility to convert any incontinent form of u…
Mechanisms of Disease: molecular insights into aseptic loosening of orthopedic implants
2007
Despite the success of treating rheumatic disorders with biologic therapies, joint replacement surgery still remains the final treatment option in many cases. Approximately 1.5 million joint arthroplastic operations are performed annually worldwide. Implant failure due to massive bone loss and aseptic loosening of prostheses, however, is a major complication of joint replacement, which can lead to high socioeconomic burdens both for the individual patient and for health-care systems. To date, there is no approved drug therapy to prevent or inhibit periprosthetic osteolysis, and aseptic loosening of prostheses can only be overcome by surgical revision. Research during the past decade, howeve…
