    Repair of superior labral tears anterior to posterior (SLAP) lesions has become an increasingly common procedure, despite the low incidence rates reported in the literature. As the incidence of these procedures increases, the surgeons will be increasingly confronted with patients with painful shoulders after SLAP repair. Persistent pain after SLAP repair is multifactorial; careful preoperative workup is necessary to elucidate the cause of pain. Simple failure of the prior SLAP repair will rarely be the cause of persistent pain. Use of tacks is especially worrisome, and suture anchor repair is preferable. Articular cartilage injuries because of either bioabsorbable or metal hardware will often create significant residual disability. Recent literature suggests that older patients may be better served by primary biceps tenodesis rather than SLAP repair.

    A region of tracheal collapse was identified by endoscopy after surgical repair of a traumatic injury to the neck in an ostrich. During periods of excitation, the ostrich would become dyspneic and collapse. A tracheal split-ring prosthesis was placed surgically to support the collapsing trachea. This technique, which is frequently used in dogs, is applicable for use in birds with collapsing trachea.

    PURPOSE OF THE STUDY To present the results of surgical repair of ruptures of the distal tendon of the biceps brachii muscle and thus show the adequacy of this treatment. MATERIAL Between 1987 and 2006, 19 patients had surgery for distal biceps tendon rupture. Only one side was affected in each patient. All patients were men between 28 and 69 years (average age, 47.5 years) at the time of injury (surgery). When the patients were evaluated at the end of 2007, 18 patients were included, because one died a year after surgery. METHODS The surgical repair always included a single-incision anatomical reattachment into the radial tuberosity. In 11 patients, a modified Mac Reynolds method with screw and washer fixation was used; in seven patients the insertion was fixed with Mitek anchors and, in one, it was sutured to the adjacent soft tissues. The average follow-up was 7 years (range, 1 to 20.5 years). The patients were evaluated for the cause of injury, their physical activity, age, dominance of the injured arm, surgical procedure and complications. RESULTS In 18 patients surgical repair was done early and, in one, at 16 days after injury. In all of them the tendon was detached from its site of insertion, but never torn. The intra-operative complications included, in one patient, bleeding owing to iatrogenic damage to a branch of the brachial artery, and difficult separation of the tendon due to its previous healed injury in another patient. Early post-operative complications included superficial skin necrosis in one patient and transient neurological deficit of the dorsal brand of the radial nerve and of the lateral cutaneous nerve of the forearm in two and one patient, respectively. The late complications were heterotropic ossification in three patients and screw migration in the one treated by the Mac Reynolds method. Excellent results were recorded in 11 patients (61 %), and good outcomes with a slight restriction of motion or muscle strength not limiting the

    Full Text Available Abstract Background Emergency repair of incarcerated incisional hernia with associated bowel obstruction in potentially or contaminated field is technically challenging due to edematous, inflamed and friable tissues with occasional need for concurrent bowel resection and carries high rates of post-operative infectious complications. The aim of this study was to retrospectively assess the wound related morbidity of use of permanent prosthetic mesh in emergency repair of incarcerated incisional hernia with associated bowel obstruction. We also describe a new technique of leaving the mesh exposed to heal by secondary intention with granulation tissue. Methods Between 2000 and 2010 a total of 60 patients underwent emergency surgery for incarcerated incisional hernia with associated bowel obstruction with placement of permanent prosthetic mesh. The wound was closed after hernia repair in 55 patients while it was left open to granulate in 5 patients. Results In the group of patients with primary wound closure, 11 patients developed superficial surgical site infection, 5 developed deep wound infection and one patient had cellulitis. These patients were treated with wound debridement and antibiotics. Mesh removal was required in one patient. There were no infections in the group of patients who had their surgical wounds left open. One patient in this group died on the fifth postoperative day from septicemia. Conclusion Use of permanent prosthetic mesh in emergency repair of incarcerated incisional hernia with associated bowel obstruction. in contaminated field is associated with high risk of wound infection.

    ABSTRACT Aim We present a novel surgical technique for repair of persistent and symptomatic cyclodialysis clefts refractory to conservative or minimally invasive treatment. Background Numerous surgical techniques have been described to close cyclodialysis clefts. The current standard approach involves intraocular repair of cyclodialysis clefts underneath a full-thickness scleral flap. Technique Our technique employs intraoperative use of a direct gonioscope to guide a nonpenetrating surgical repair. Subsequently, a significantly less invasive, nonpenetrating technique utilizing a partial-thickness scleral flap can be performed that reduces potential risks associated with intraocular surgery. The direct gonioscope is also used for confirmation of adequate surgical closure of the cyclodialysis cleft prior to completion of surgery. This technique has been successfully carried out to repair traumatic chronic cyclodialysis clefts associated with hypotony in two patients. There were no significant adverse events as a result of using this technique. Conclusion The novel technique described increases the likelihood of successful and permanent repair of cyclodialysis clefts with resolution of symptoms associated with hypotony, through direct intraoperative visualization of the cleft. Clinical significance Gonioscopically guided nonpenetrating cyclodialysis cleft repair offers significant benefits over previously described techniques. Advantages of our technique include gonioscopic cleft visualization, enabling accurate localization of the area requiring repair, and subsequent confirmation of adequate closure of the cleft. Using a partial-thickness scleral flap is also less invasive and reduces risks associated with treatment of this potentially challenging complication of ocular trauma.

    The aim of the study was to assess the clinical outcomes of surgical repair of uterine cesarean scar defects with sonography (US). Seven nonpregnant women with history of cesarean section and a large uterine scar defect were enrolled. The surgical repair was performed by minilaparotomy. The US assessment of the uterine scar was performed using a standardized approach at baseline, then at a first visit 2-3 days following the surgical intervention (V1) and at a follow-up visit 3 months later (V2). Residual myometrial thickness (RMT), width, and depth of the scar defect were measured. The mean RMT increased significantly from 1.9 mm at baseline to 8.8 mm at V1 and 8.0 mm at V2. No intraoperative complications were observed. Postmenstrual spotting and abdominal pain reported preoperatively resolved after the operation. A surgical repair procedure for an incompletely healed uterine cesarean scar is effective in increasing RMT thickness, decreasing the depth of the scar, and reducing symptoms related to the cesarean section scar defect. Further studies on post-repair pregnancy outcomes are required to evaluate whether the procedure affects the rate of cesarean scar pregnancy, morbidly adherent placenta, and/or uterine scar dehiscence and rupture. The repair of a cesarean scar defect is recommended only for symptomatic women. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:455-460, 2017. © 2017 Wiley Periodicals, Inc.

    We describe a forme frustrée of hammock valve involving only the posterior mitral leaflet. Three adult patients were referred to surgery with the diagnosis of severe mitral regurgitation due to fibrosis of the posterior mitral leaflet. The final diagnosis was done intraoperatively. In all of them the posterior leaflet was attached to some accessory papillary muscles arranged en palisade, with three to four fused muscle heads producing restrictive leaflet motion in systole. Repair consisted in division of the papillary muscles, patch augmentation, and ring annuloplasty. This previously unreported lesion is congenital but manifests itself in adulthood.

    Full Text Available Purpose: To report visual and anatomic outcomes of chronic macular hole surgery, with analysis of pre-operative OCT-based hole size and post-operative closure type. Settings and Design: An IRB-approved, retrospective case series of 26 eyes of 24 patients who underwent surgery for stage 3 or 4 idiopathic chronic macular holes at a tertiary care referral center. Statistical Analysis: Student′s t-test. Results: Nineteen of 26 eyes (73% had visual improvement after surgery on most recent exam. Twenty-one of 26 eyes (81% achieved anatomic closure; 16 of 26 eyes (62% achieved type 1, and five of 26 eyes (19% achieved type 2 closure. Post-operative LogMAR VA for type 1 closure holes (0.49 was significantly greater than for type 2 closure and open holes (1.26, P < 0.003 and 1.10, P < 0.005, respectively, despite similar pre-operative VA (P = 0.51 and 0.68, respectively. Mean pre-operative hole diameter for eyes with type 1 closure, type 2 closure, and holes that remained open were 554, 929, and 1205 microns, respectively. Mean pre-operative hole diameter was significantly larger in eyes that remained open as compared to eyes with type 1 closure (P = 0.015. Conclusion: Vitrectomy to repair chronic macular holes can improve vision and achieve long-term closure. Holes of greater than 3.4 years duration were associated with a greater incidence of remaining open and type 2 closure. Larger holes (mean diameter of 1205 microns were more likely to remain open after repair.

    Goals for treating congenital heart defects are becoming increasingly focused on the long-term, targeting solutions that last into adulthood. Although this shift has motivated the modification of many current surgical procedures, there remains a great deal of room for improvement. We present a new methodological component for tetralogy of Fallot (TOF) repair that aims to improve long-term outcomes. The current gold standard for TOF repair involves the use of echocardiography (ECHO) for measuring the pulmonary valve (PV) diameter. This is then used, along with other factors, to formulate a Z-score that drives surgical preparation. Unfortunately this process can be inaccurate and requires a mid-operative confirmation that the pressure gradient across the PV is not excessive. Ideally, surgeons prefer not to manipulate the PV as this can lead to valve insufficiency. However, an excessive pressure gradient across the valve necessitates surgical action. We propose the use of computational fluid dynamics (CFD) to improve preparation for TOF repair. In our study, pre-operative CT data were segmented and reconstructed, and a virtual surgical operation was then performed to simulate post-operative conditions. The modified anatomy was used to drive CFD simulation. The pressure gradient across the pulmonary valve was calculated to be 9.24mmHg, which is within the normal range. This finding indicates that CFD may be a viable tool for predicting post-operative pressure gradients for TOF repair. Our proposed methodology would remove the need for mid-operative measurements that can be both unreliable and detrimental to the patient.

    Full Text Available Abstract Background Cerebrospinal fluid leaks (CSF result from an abnormal communication between the subarachnoid space and the extracranial space. Approximately 90% of CSF leak at the anterior skull base manifests as rhinorrhea and can become life-threatening condition. Endoscopic sinus surgery (ESS has become a common otolaryngologist procedure. The aim of this article is to consider our experience and to evaluate the outcomes in patients who underwent a purely endoscopic repair of CSF leaks of the anterior skull base. Findings Retrospective chart review was performed of all patients surgically treated for CSF leaks presenting to the Section of Nasal and Sinus Disorders at the Service of ENT–Head and Neck Surgery, University Hospital Complex of Santiago de Compostela (CHUS, between 2004 and 2010. A total of 30 patients who underwent repair CSF leak by ESS. The success rate was 93.4% at the first attempt; only two patients (6.6% required a second surgical procedure, and none of it was necessary to use a craniotomy for closure. Follow-up periods ranged from 4 months to 6 years. Conclusion Identifying the size, site, and etiology of the CSF leak remains the most important factor in the surgical success. It is generally accepted that the ESS have made procedures minimally invasive, and CSF leak is now one of its well-established indications with low morbidity and high success rate, with one restriction for fistulas of the posterior wall of the frontal sinus should be repaired in conjunction with open techniques.

    Open repair is still considered the reference standard for long-term repair of abdominal aortic aneurysms (AAA). In contrast to endovascular aneurysm repair (EVAR), patients with open surgical repair of AAA are not routinely followed up with imaging. Although complications following EVAR are widely recognized and routinely identified on follow-up imaging, complications also do occur following open surgical repair. With frequent use of multi-slice computed tomography (CT) angiography (CTA) in vascular patients, there is now improved recognition of the potential complications following open surgical repair. Many of these complications are increasingly being managed using endovascular techniques. The aim of this review is to illustrate a variety of potential complications that may occur following open surgical repair and to demonstrate their management using both surgical and endovascular techniques.

    Full Text Available Purpose: To report the outcomes of two different surgical techniques for the repair of late onset bleb leakage following trabeculectomy. Methods: This retrospective study includes 21 eyes of 20 patients with prior trabeculectomy and late-onset bleb leaks; 14 eyes underwent excision of the filtering bleb together with conjunctival advancement while in the other 7 eyes the bleb was retained but de-epithelialized before conjunctival advancement. Success was defined as resolution of leakage with no need for additional glaucoma surgery together with intraocular pressure (IOP of 5-21 mmHg. Complete and qualified success was considered when the above mentioned was achieved without or with glaucoma medications, respectively. Results: Mean duration of follow-up was 20.3΁14.4 months. No significant difference was observed between the two groups in terms of complete, qualified and overall success rates (P>0.05, however more antiglaucoma medications were necessary in the bleb excision group (P=0.02. Conclusions: Both surgical techniques of bleb repair were comparably effective, however the bleb de-epithelialization technique was associated with less need for glaucoma medications after the procedure.

    Despite limited data, the necessity for immediate surgical intervention in octogenarians with acute type A aortic dissection (AAD) has recently been questioned because the surgical risk may outweigh its potential benefits. At the same time, evolving stent graft technologies are pushing in the market for pathology within the ascending aorta, even for treatment of AAD. Against this background, we analyzed our institutional experience in this patient cohort during the last 8 years. Between October 2005 and October 2013, 39 patients aged older than 80 years (82 ± 2 years) underwent surgical repair for AAD, of which 29 patients (74%) were men. Owing to patient age and comorbidities, we aimed to limit the operation to supracoronary hemiarch replacement whenever possible. Clinical data were prospectively entered into our institutional database. Late follow-up was 3.6 ± 2.8 years and was 100% complete. Hemiarch replacement was performed in 32 patients (82%), and full arch replacement was necessary in the remaining 7. In 31 patients (79%), the aortic root could be glued and reconstructed or remained untouched. The remaining 8 patients (21%) underwent the bio-Bentall procedure. Mean ventilation time was 46 ± 23 hours, and the intensive care unit stay was 5 ± 9 days. We observed new postoperative permanent neurologic deficits in 2 patients (5%) and transient neurologic deficits in 3 (8%). The 30-day mortality was 26% (n = 10). Kaplan-Meier estimates for late survival were 46% ± 16% at 5 years. Given the guidelines regarding the predicted risk of death in patients with untreated AAD, current data suggest a survival benefit with immediate open surgical intervention even in octogenarians. Similarly to the early days of transcatheter-based aortic valve implantation, open surgical reference data are warranted to set the bar for upcoming endovascular treatment of AAD in octogenarians.

  1. Cartilage repair and joint preservation: medical and surgical treatment options.

    Articular cartilage defects are most often caused by trauma and osteoarthritis and less commonly by metabolic disorders of the subchondral bone, such as osteonecrosis and osteochondritis dissecans. Such defects do not heal spontaneously in adults and can lead to secondary osteoarthritis. Medications are indicated for symptomatic relief. Slow-acting drugs in osteoarthritis (SADOA), such as glucosamine and chondroitin, are thought to prevent cartilage degeneration. Reconstructive surgical treatment strategies aim to form a repair tissue or to unload compartments of the joint with articular cartilage damage. In this article, we selectively review the pertinent literature, focusing on original publications of the past 5 years and older standard texts. Particular attention is paid to guidelines and clinical studies with a high level of evidence, along with review articles, clinical trials, and book chapters. There have been only a few randomized trials of medical versus surgical treatments. Pharmacological therapies are now available that are intended to treat the cartilage defect per se, rather than the associated symptoms, yet none of them has yet been shown to slow or reverse the progression of cartilage destruction. Surgical débridement of cartilage does not prevent the progression of osteoarthritis and is thus not recommended as the sole treatment. Marrow-stimulating procedures and osteochondral grafts are indicated for small focal articular cartilage defects, while autologous chondrocyte implantationis mainly indicated for larger cartilage defects. These surgical reconstructive techniques play a lesser role in the treatment of osteoarthritis. Osteotomy near the knee joint is indicated for axial realignment when unilateral osteoarthritis of the knee causes axis deviation. Surgical reconstructive techniques can improve joint function and thereby postpone the need for replacement of the articular surface with an artificial joint.

    Lateral sided hip pain frequently presents to the orthopaedic clinic. The most common cause of this pain is trochanteric bursitis. This usually improves with conservative treatment. In a few cases it doesn't settle and warrants further investigation and treatment. We present a series of 28 patients who underwent MRI scanning for such pain, 16 were found to have a tear of their abductors. All 16 underwent surgical repair using multiple soft tissue anchors inserted into the greater trochanter of the hip to reattach the abductors. There were 15 females and 1 male. All patients completed a self-administered questionnaire pre-operatively and 1 year post-operatively. Data collected included: A visual analogue score for hip pain, Charnley modification of the Merle D'Aubigne and Postel hip score, Oxford hip score, Kuhfuss score of Trendelenburg and SF36 scores.Of the 16 patients who underwent surgery 5 had a failure of surgical treatment. There were 4 re ruptures, 3 of which were revised and 1 deep infection which required debridement. In the remaining 11 patients there were statistically significant improvements in hip symptoms. The mean change in visual analogue score was 5 out of 10 (p=0.0024) The mean change of Oxford hip score was 20.5 (p=0.00085). The mean improvement in SF-36 PCS was 8.5 (P=0.0020) and MCS 13.7 (P=0.134). 6 patients who had a Trendelenburg gait pre-surgery had normal gait 1 year following surgery.We conclude that hip abductor mechanism tear is a frequent cause of recalcitrant trochanteric pain that should be further investigated with MRI scanning. Surgical repair is a successful operation for reduction of pain and improvement of function. However there is a relatively high failure rate.

    Lumbar hernia is the protrusion of intraperitoneal or extraperitoneal contents through a defect of the posterolateral abdominal wall. Barbette was the first, in 1672, to suggest the existence of lumbar hernias. The first case was reported by Garangeot in 1731. Petit and Grynfeltt delineated the boundaries of the inferior and superior lumbar triangles in 1783 and 1866, respectively. These two anatomical sites account for about 95 per cent of lumbar hernias. Approximately 20 per cent of lumbar hernias are congenital. The rest are either primarily or secondarily acquired. The most common cause of primarily acquired lumbar hernias is increased intra-abdominal pressure. Secondarily acquired lumbar hernias are associated with prior surgical incisions, trauma, and abscess formation. During embryologic development, weakening of the area of the aponeuroses of the layered abdominal muscles that derive from somitic mesoderm, which invades the somatopleure, may potentially lead to lumbar hernias. Repair of lumbar hernias should be performed as early as possible to avoid incarceration and strangulation. The classic repair technique uses the open approach, where closure of the defect is performed either directly or using prosthetic mesh. The laparoscopic approach, either transabdominal or extraperitoneal, is an alternative.

    Separation of the levator ani muscles from pubic bone is a common major levator trauma that may occur in vaginal delivery and is associated with pelvic floor dysfunctions. We describe a novel ultrasound-guided technique to repair these muscles. A 33-year-old woman presented with a history of difficult vaginal delivery and complaint of numbness and weakness of the vagina. In evaluation, bilateral levator defects were diagnosed by physical examination, three-dimensional endovaginal ultrasound, and magnetic resonance imaging. With ultrasound guidance the detached ends of muscles were tagged and sutured to their insertion points at the pubic bone. The patient's normal anatomy was restored with the return to normal pelvic floor tone. A follow-up ultrasound showed restored levator anatomy at 3 months.

    Spigelian hernia (1-2% of all hernias) is the protrusion of preperitoneal fat, peritoneal sac, or organ(s) through a congenital or acquired defect in the spigelian aponeurosis (i.e., the aponeurosis of the transverse abdominal muscle limited by the linea semilunaris laterally and the lateral edge of the rectus muscle medially). Mostly, these hernias lie in the "spigelian hernia belt," a transverse 6-cm-wide zone above the interspinal plane; lower hernias are rare and should be differentiated from direct inguinal or supravescical hernias. Although named after Adriaan van der Spieghel, he only described the semilunar line (linea Spigeli) in 1645. Josef Klinkosch in 1764 first defined the spigelian hernia as a defect in the semilunar line. Defects in the aponeurosis of transverse abdominal muscle (mainly under the arcuate line and more often in obese individuals) have been considered as the principal etiologic factor. Pediatric cases, especially neonates and infants, are mostly congenital. Embryologically, spigelian hernias may represent the clinical outcome of weak areas in the continuation of aponeuroses of layered abdominal muscles as they develop separately in the mesenchyme of the somatopleura, originating from the invading and fusing myotomes. Traditionally, repair consists of open anterior herniorraphy, using direct muscle approximation, mesh, and prostheses. Laparoscopy, preferably a totally extraperitoneal procedure, or intraperitoneal when other surgical repairs are planned within the same procedure, is currently employed as an adjunct to diagnosis and treatment of spigelian hernias. Care must be taken not to create iatrogenic spigelian hernias when using laparoscopy trocars or classic drains in the spigelian aponeurosis.

    We present the long-term results of surgical repair of a traumatic rupture of the quadriceps tendon in a group of 24 patients with a mean age of 58 years. There were 21 male and 3 female patients. Fifteen patients were seen for clinical control after a mean follow-up of 75 months and they all presented with some quadriceps muscle atrophy. Twelve patients had normal knee mobility, three had a flexion deformity of 10 degrees and two had less than 120 degrees of knee flexion. Active knee extension was normal in all patients. Three patients experienced some decrease in stability of their knee joint. Subjectively all patients were satisfied with the result. Nine patients underwent a Cybex-test for evaluation of the isokinetic force of knee flexion and extension, with a comparison between the injured and the uninjured side. For concentric force there was a mean deficit at low speed of 36.1% for the quadriceps muscle; at high speed it was 28.2%. For the knee flexors, the deficits were 30.7% and 27.2% respectively. Regarding eccentric force, the mean deficit for knee extensors was 13.8% and 0.25% respectively and for knee flexors 6.5% and 5.5% respectively.

    Perineal hernia is the protrusion into the perineum of intraperitoneal or extraperitoneal contents through a congenital or acquired defect of the pelvic diaphragm. The first case was reported by de Garangeot in 1743. Perineal hernias may occur anteriorly or posteriorly to the superficial transverse perineal muscles. Congenital perineal hernia is a rare entity. Failure of regression of the peritoneal cul de sac of the embryo is considered a predisposing factor for hernia formation. Acquired perineal hernias are primary or secondary. Primarily acquired perineal hernias are caused by factors associated with increased intra-abdominal pressure. They are more common in females as a result of the broader female pelvis and the attenuation of the pelvic floor during pregnancy and childbirth. Secondarily acquired perineal hernias are incisional hernias associated with extensive pelvic operations such as abdominoperineal resection of the anorectum and pelvic exenteration. Pain in the perineal area, intestinal obstruction, topical skin erosion, and difficulty with urination necessitate the surgical repair of a perineal hernia. This can be accomplished through transabdominal, perineal, or combined abdominoperineal approaches. The defect in the muscles of the pelvic diaphragm may be closed either with direct suturing or by using autogenous tissues or synthetic mesh.

    Aortic valve reconstruction using leaflet grafts made from autologous pericardium is an effective surgical treatment for some forms of aortic regurgitation. Despite favorable outcomes in the hands of skilled surgeons, the procedure is underutilized because of the difficulty of sizing grafts to effectively seal with the native leaflets. Difficulty is largely due to the complex geometry and function of the valve and the lower distensibility of the graft material relative to native leaflet tissue. We used a structural finite element model to explore how a pericardial leaflet graft of various sizes interacts with two native leaflets when the valve is closed and loaded. Native leaflets and pericardium are described by anisotropic, hyperelastic constitutive laws, and we model all three leaflets explicitly and resolve leaflet contact in order to simulate repair strategies that are asymmetrical with respect to valve geometry and leaflet properties. We ran simulations with pericardial leaflet grafts of various widths (increase of 0%, 7%, 14%, 21% and 27%) and heights (increase of 0%, 13%, 27% and 40%) relative to the native leaflets. Effectiveness of valve closure was quantified based on the overlap between coapting leaflets. Results showed that graft width and height must both be increased to achieve proper valve closure, and that a graft 21% wider and 27% higher than the native leaflet creates a seal similar to a valve with three normal leaflets. Experimental validation in excised porcine aortas (n=9) corroborates the results of simulations. PMID:22341628

    It is challenging to establish one-lung ventilation in difficult airway patients. Surgical pneumothorax under spontaneous breathing to obtain well-collapsed lung is a feasible method for thoracic surgery. A 76-year-old man with right empyema was scheduled for decortication. The patient had limited mouth opening due to facial cellulitis extending from the left cheek to neck. Generally, lung isolation is achieved by double-lumen endotracheal tube or bronchial blocker. Double-lumen tube insertion is difficult for patients with limited mouth opening and right-side placement of bronchial blocker usually causes insufficient deflation. We introduce an alternative lung isolation technique by surgical pneumothorax under spontaneous breathing simply with an endotracheal tube placement. This technique has never been applied into the management of difficult one-lung ventilation. By this method, we provide an ideal surgical condition with safer, less time-consuming, and less skill-demanding anesthesia. It would be an alternative choice for management of one-lung ventilation in the difficult lung isolation patient.

    Rectovaginal fistulas can occur from both obstetric and nonobstetric (eg, inflammatory bowel disease, iatrogenic, or traumatic) etiologies. Current data on factors contributing to rectovaginal repair success or failure are limited, making adequate patient counseling difficult. Our objective was to compare outcomes of transperineal rectovaginal fistula repair performed in a single referral center on women with obstetric and nonobstetric causes. We performed a retrospective cohort study of women who had a transperineal rectovaginal fistula repair performed by a urogynecologist at the University of Michigan from 2005 to 2015. Data were obtained by chart review and included demographics, medical comorbidities, fistula etiology, history of a prior fistula repair, failure of current repair, time to failure, and operative details. Repair failure was defined as fistula symptoms with presence of recurrent fistula on exam or imaging in the postoperative follow-up period. Comparisons between the obstetric and nonobstetric cohorts were performed using χ, Fisher exact, and Wilcoxon rank sum tests. Relative risks were calculated to identify predictors of failure. Eighty-eight women were included-53 obstetric and 35 nonobstetric fistulas. The overall fistula repair failure rate was 22.7% (n = 20). Median follow-up was 157.0 days (range, 47.5-402.0). Of all the factors, only nonobstetric etiology was significantly associated with an increased risk of repair failure (relative risk, 3.53 [range, 1.50-8.32]; P = 0.004. Nonobstetric rectovaginal fistulas have a nearly 4-fold increased risk of repair failure compared with obstetric fistulas. Our results will help surgeons adequately counsel patients on potential outcomes of surgical repair of obstetric versus nonobstetric rectovaginal fistulas.

    Complex iliac anatomy including extreme tortuosity constitutes a relative contraindication for endovascular abdominal aortic aneurysm repair with additional risk of limb-graft occlusion. The Gore Excluder limb-graft is a flexible stent-graft, which adapts easily to iliac tortuosity. Nevertheless, the presence of the stiff guide wire does not always allow for an ideal apposition of the stent graft to the angulated common iliac artery vessel wall. We describe herein a modified technique for Gore Excluder limb-graft deployment with partial removal of the stiff wire in cases with difficult tortuous or narrow iliac arteries during endovascular abdominal aortic aneurysm repair. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available Background: Measurement of treatment outcome is important in estimating the success of cleft management. The aim of this study was to assess the surgical outcome of cleft lip and palate surgery. Patients and Methods: The surgical outcome of 131 consecutive patients with cleft lip and palate surgeries between October 2008 and December 2010 were prospectively evaluated at least 4 weeks postoperatively. Data collected included information about the age, sex, type of cleft defects, and type of surgery performed as well as postoperative complications. For cleft lip repair, the Pennsylvania lip and nose (PLAN score was used to assess the surgical outcome, while the integrity of the closure was used for cleft palate repair. Results: A total of 92 patients had cleft lip repair and 64 had palate repair. Overall, 68.8% cases of cleft lip and palate repair had good outcomes; 67.9% of lip repairs had good lip and nose scores, while 70.2% of palatal repair had a good surgical outcome. Oro-fistula was observed in 29.8% of cleft palate repairs Inter-rater reliability coefficient was substantially significant. Conclusions: The fact that 25.7% of those treated were aged >1 year suggests a continued need to enlighten the public on the availability of cleft lip and palate expertise and treatment. Although an overall good treatment outcome was demonstrated in this study, the nasal score was poorer than the lip score. Complication rate of about 14% following surgical repair is consistent with previous reports in the literature.

  16. Entrapment of Common Peroneal Nerve by Surgical Suture following Distal Biceps Femoris Tendon Repair

    Directory of Open Access Journals (Sweden)

    Aki Fukuda

    2016-01-01

    Full Text Available We describe entrapment of the common peroneal nerve by a suture after surgical repair of the distal biceps femoris tendon. Complete rupture of the distal biceps femoris tendon of a 16-year-old male athlete was surgically repaired. Postoperative common peroneal nerve palsy was evident, but conservative treatment did not cause any neurological improvement. Reexploration revealed that the common peroneal nerve was entrapped by the surgical suture. Complete removal of the suture and external neurolysis significantly improved the palsy. The common peroneal nerve is prone to damage as a result of its close proximity to the biceps femoris tendon and it should be identified during surgical repair of a ruptured distal biceps femoris tendon.

    2017-03-01

    Two machine-learning methods were evaluated to help automate the quality control process for mitigating damage sites on laser optics. The mitigation is a cone-like structure etched into locations on large optics that have been chipped by the high fluence (energy per unit area) laser light. Sometimes the repair leaves a difficult to detect remnant of the damage that needs to be addressed before the optic can be placed back on the beam line. We would like to be able to automatically detect these remnants. We try Deep Learning (convolutional neural networks using features autogenerated from large stores of labeled data, like ImageNet) and find it outperforms ensembles of decision trees (using custom-built features) in finding these subtle, rare, incomplete repairs of damage. We also implemented an unsupervised method for helping operators visualize where the network has spotted problems. This is done by projecting the credit for the result backwards onto the input image. This shows regions in an image most responsible for the networks decision. This can also be used to help understand the black box decisions the network is making and potentially improve the training process.

    A new lighting device for open surgery of difficult access wounds was designed: the Extender add-on. The performance of the Extender is evaluated and compared with the conventional solutions used in the operating room (OR) on illumination quality. A cylindrical setup was built to measure the distribution of light in a simulated pelvic wound. The light was provided by a head-mounted light, an OR light, and a pair of Extender prototypes. The results showed that the Extender prototypes provided 12.2 lumens inside the wound, whereas the head-mounted light gave 5.7 lumens. The Extenders provided smoothly angular distributed light from 0° to 180°, whereas the head-mounted light and OR light only provided light from 115° to 180°. The Extender prototypes had a promising performance in terms of light distribution. It is expected that a more accurately produced Extender will increase performance in terms of illumination quantity and illumination distribution smoothness even further.

  19. Semitendinosus and gracilis free muscle-tendon graft for repair of massive rotator cuff tears: surgical technique.

    Gigante, Antonio; Bottegoni, Carlo; Milano, Giuseppe; Riccio, Michele; Dei Giudici, Luca

    2016-01-01

    Massive rotator cuff tears are difficult to treat surgically due to retraction, degeneration and fraying of the ends of torn tendons, severe fatty infiltration and atrophy of the respective muscles. Procedures developed to close the gap between the rotator cuff and the greater tuberosity of the humerus, such as soft tissue release may be inadequate for large tears. Human or porcine dermal allografts still have uncertain benefits, and tendon transfers seem to be associated with poor outcomes, donor site morbidity and altered mechanics. Reverse total shoulder arthroplasty has limited durability and is not indicated in young patients with high functional demands. We developed a new technique for repairing massive rotator cuff tears by semitendinosus and gracilis myotendinous grafting. This novel therapeutic option allows massive rotator cuff tears to be repaired using autologous material that is adequate and adaptable, making it possible to cover any width of defect. The technique is low-invasive and not technically demanding, with minimal donor site morbidity.

    2015-01-01

    Advanced hip imaging and surgical findings have demonstrated that a common cause of greater trochanteric pain syndrome (GTPS) is gluteal tendon tears. Conservative measures are initially employed to treat GTPS and manage gluteal tears, though patients frequently undergo multiple courses of non-operative treatment with only temporary pain relief. Therefore, a number of surgical treatment options for recalcitrant GTPS associated with gluteal tears have been reported. These have included open trans-osseous or bone anchored suture techniques, endoscopic methods and the use of tendon augmentation for repair reinforcement. This review describes the anatomy, pathophysiology and clinical presentation of gluteal tendon tears. Surgical techniques and patient reported outcomes are presented. This review demonstrates that surgical repair can result in improved patient outcomes, irrespective of tear aetiology, and suggests that the patient with "trochanteric bursitis" should be carefully assessed as newer surgical techniques show promise for a condition that historically has been managed conservatively.

    The research objective of the current systematic literature review is to classify the laparoscopic niche repair according to the IDEAL framework of 'innovation stages' and to recommend the required research setting to facilitate safe and properly timed implementation of the technique. In doing so, we are also able to evaluate the practical applicability of the IDEAL framework. A systematic search of the available literature on laparoscopic niche repair was performed in PubMed, Embase, and the Wiley/Cochrane library. Articles were classified according to the IDEAL framework and recommendations were given on additional required research before the technique can be safely implemented. Practical applicability of the IDEAL framework was also evaluated. Introduction of laparoscopic niche repair matches Idea (1) and Development (2a), according to the stages of IDEAL framework, although most studies are retrospective and complications have not been registered structurally in a considerable number of the articles. As feasibility and safety have been more or less established and surgery has been further developed we enter stage 2b (Exploration) and need prospective trials preferably comparing the effectiveness of laparoscopic niche repair to expectant management, the current standard care. Available studies were classified with the use of the IDEAL framework, achieving an overall IDEAL stage to be 2a Development. As clinical outcomes, though poorly registered, have been substantially improved, laparoscopic niche repair needs to be carried forward by more advanced study designs. Copyright © 2017 Elsevier B.V.

    2015-01-01

    Background Surgical repair of a torn rotator cuff is based on the belief that repairing the tear is necessary to restore normal glenohumeral joint (GHJ) mechanics and achieve a satisfactory clinical outcome. Hypothesis Dynamic joint function is not completely restored by rotator cuff repair, thus compromising shoulder function and potentially leading to long-term disability. Study Design Controlled laboratory study and Case series; Level of evidence, 4. Methods Twenty-one rotator cuff patients and 35 control participants enrolled in the study. Biplane radiographic images were acquired bilaterally from each patient during coronal-plane abduction. Rotator cuff patients were tested at 3, 12, and 24 months after repair of a supraspinatus tendon tear. Control participants were tested once. Glenohumeral joint kinematics and joint contact patterns were accurately determined from the biplane radiographic images. Isometric shoulder strength and patient-reported outcomes were measured at each time point. Ultrasound imaging assessed rotator cuff integrity at 24 months after surgery. Results Twenty of 21 rotator cuff repairs appeared intact at 24 months after surgery. The humerus of the patients’ repaired shoulder was positioned more superiorly on the glenoid than both the patients’ contralateral shoulder and the dominant shoulder of control participants. Patient-reported outcomes improved significantly over time. Shoulder strength also increased over time, although strength deficits persisted at 24 months for most patients. Changes over time in GHJ mechanics were not detected for either the rotator cuff patients’ repaired or contralateral shoulders. Clinical outcome was associated with shoulder strength but not GHJ mechanics. Conclusion Surgical repair of an isolated supraspinatus tear may be sufficient to keep the torn rotator cuff intact and achieve satisfactory patient-reported outcomes, but GHJ mechanics and shoulder strength are not fully restored with current

    Aortic coarctation is a frequent congenital defect requiring early surgical treatment. Late complications of these surgical procedures can be fatal as in the case of a ruptured anastomotic pseudoaneurysm. We present a case of a 49-year-old man presenting with hemorrhagic shock due to this complication who was successfully treated by endovascular techniques with implantation of two stent grafts. This case illustrates the fact that endovascular aortic repair is feasible, certainly less invasive and very efficient for this type of complication when used in an experienced center.

    2011-09-01

    Full Text Available Background: Coarctation of the aorta is a discrete stenosis of the proximal thoracic aorta. The common clinical pattern is congestive heart failure in infancy. Treatment methods include balloon angioplasty and surgical repair in this age group. Percutaneous balloon angioplasty is a less invasive method for the repair of discrete coarctation but remains controversial as a primary treatment strategy for a native coarctation. This study aimed to compare the effectiveness and outcome of balloon angioplasty and surgical repair in coarctation infants younger than 1 year old.Methods: This retrospective study evaluated the results of the two methods in 167 patients younger than one year old admitted into a tertiary heart center pediatric ward with the diagnosis of coarctation of the aorta: Balloon angioplasty was done for 55 and surgical repair for 112 infants. Patients with previous interventions were not included in this study. Results: Primary results revealed no significant difference in the effectiveness of the two methods (p value = 0.0601. While the rate of recurrent coarctation was significantly lower in the surgery group [19 (17% vs. 11 (20%, p value = 0.0470], the mortality rate was lower in the balloon angioplasty method [5 (5.5% vs. 13 (11.6%, p value = 0.039]. Our multivariate logistic regression model, however, showed no statistically significant difference (p value = 0.120.Conclusion: Because of the incidence of re-coarctation, balloon angioplasty compared with surgical repair did not confer an improved outcome for our infants’ coarctation.

    Transcatheter aortic valve implantation, as well as interventional mitral valve repair, offer reasonable therapeutic options for high-risk surgical patients. We report a rare case of early post-interventional aortic valve prosthesis migration to the left ventricular outflow tract, with paravalvular leakage and causing severe mitral valve regurgitation. Initial successful interventional mitral valve repair using a clipped edge-to-edge technique revealed, in a subsequent procedure, the recurrence of mitral valve regurgitation leading to progressive heart failure and necessitating subsequent surgical aortic and mitral valve replacement.

    2010-12-01

    We report on a 29-year-old woman with severe hemolytic anemia following mitral valve annuloplasty. Although hemolysis due to mechanical prosthetic mitral valve is well recognized, hemolytic anemia associated with mitral valve repair is an uncommon condition. Reoperation may be considered if the patient has serious and persistent anemia. Although valve replacement is suggested to be a unique intervention, it may not be the solution every time because of mechanical effects. Various mechanisms of hemolysis related to mitral valve repair were suggested, but sufficient and precise data is not available. In this case, we tried to emphasize whether all hemolytic anemias that occur after mitral valve repair require surgical treatment.

    Full Text Available Historically, the surgical treatment of flexor tendon injuries has always been associated with controversy. It was not until 1967, when the paper entitled Primary repair of flexor tendons in no man’s land was presented at the American Society of Hand Surgery, which reported excellent results and catalyzed the implementation of this technique into world-wide practice. We present an up to date literature review using PubMed and Google Scholar where the terms flexor tendon, repair and rehabilitation were used. Topics covered included functional anatomy, nutrition, biomechanics, suture repair, repair site gapping, and rehabilitation. This article aims to provide a comprehensive and complete overview of flexor tendon repairs.

    The objectives were (1) to compare the morbidity and mortality of patients with hip fractures surgically repaired within and after 48 hours of the occurrence of fracture and (2) to establish whether timing of repair alone had a major role in determining how the patients fared after the surgical repair or whether comorbidities also affected outcomes. The study involved the medical records of 49 patients (aged 51 to 99 years) admitted to Coney Island Hospital between January 2003 and January 2004 with a primary diagnosis of hip fracture who underwent surgical repair. Analysis of data was done by retrospective chart review of patients admitted with the diagnosis of hip fracture to an acute care hospital setting. Follow-up continued until the patients were transferred to a rehabilitation facility for physical or occupational therapy after surgery. The preoperative health status of each patient was assessed by cardiopulmonary risk index score, based on comorbid conditions, and postoperative outcome was determined by complications (such as bed sores, pneumonia, urinary tract infection, deep vein thrombosis, or pulmonary embolism) or death. Patients who underwent early surgical repair (within 48 hours) had fewer postoperative complications (14.7%, as compared with 33.3% in the group undergoing surgery >48 hours after fracture). CPRI scores in the early and delayed surgery groups were also compared with regard to postoperative mortality and morbidity. It appeared that there was a higher statistical correlation between CPRI scores and complications among patients in the early surgery group (P=0.39) and an insignificant correlation among patients in the delayed surgery group (P=0.07). Surgical repair of hip fractures within the first 48 hours was associated with better health outcomes in a nationally representative sample, as observed in an acute care facility, irrespective of comorbid conditions.

    Full Text Available We present the case of a 54-year-old woman in which a diffuse congenital supravalvular aortic stenosis (SVAS was associated with a severe aortic valve incompetence and heavy calcification of the aortic annulus. Repair consisted in resection of the ascending aorta, patch augmentation of the hypoplastic aortic root and annulus, placement of a 20 mm Dacron tubular graft (Vascutek, Renfrewshire, UK and aortic valve replacement with a mechanical prosthesis (Sorin, Turin, Italy. Follow-up echocardiography demonstrated normal prosthetic valve function and a postoperative three-dimensional computed tomographic scan showed a normal shape of the reconstructed ascending aorta.

    2009-06-01

    All cases of lateral epicondylitis surgically treated in Dr. Pruzansky's office practice between October 1986 and December 2005 yielded 24 elbows for this study. Patients were treated with surgical débridement and direct repair to bone through bone tunnels (18 elbows), repair with suture anchors (3 elbows), or augmentation with autologous tendon graft and reattachment to bone via suture anchors (3 elbows). This series represents the earliest reattachment cases to be reported, and with the longest follow-up. Mean follow-up (both telephone and office interviews) was 64.7 months. All patients reported satisfaction and graded their outcomes as good or excellent. Mean time to full painless preinjury level of use of the elbow was 4.3 months for patients who underwent simple repair and 2.75 months for patients repaired with a graft. Surgical reattachment of the débrided extensor tendon of origin of the elbow to bone, either directly or with autologous tendon graft, provided pain relief and return to preinjury level of function in a predictable manner. Both primary repair and tendon graft procedures can be used in primary and salvage surgeries in tennis elbow cases in which conservative treatment fails.

    Rotator cuff tears are the most common musculoskeletal injury occurring in the shoulder. Current surgical repair fails to heal in 20% to 95% of patients, depending on age, size of the tear, smoking, time of repair, tendon quality, muscle quality, healing response, and surgical treatments. These problems are worsened by the limited healing potential of injured tendons attributed to the presence of degenerative changes and relatively poor vascularity of the cuff tendons. Development of new techniques to treat rotator cuff tears requires testing in animal models to assess safety and efficacy before clinical testing. Hence, it is important to evaluate appropriate animal models for rotator cuff research with degeneration of tendons, muscular atrophy, and fatty infiltration similar to humans. This report reviews current clinical treatments and preclinical approaches for rotator cuff tear repair. The review will focus on current clinical surgical treatments, new repair strategies under clinical and preclinical development, and will also describe different animal models available for rotator cuff research. These findings and future directions for rotator cuff tear repair will be discussed. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

    Full Text Available Extracorporeal membrane oxygenation (ECMO has been used successfully in critically ill patients with traumatic lung injury and offers an additional treatment modality. ECMO is mainly used as a bridge treatment to delayed surgical management; however, only a few case reports have presented the successful application of ECMO as intraoperative support during the surgical repair of traumatic bronchial injury. A 38-year-old man visited our hospital after a blunt chest trauma. His chest imaging showed hemopneumothorax in the left hemithorax and a finding suspicious for left main bronchus rupture. Bronchoscopy was performed and confirmed a tear in the left main bronchus and a congenital tracheal bronchus. We decided to provide venovenous ECMO support during surgery for bronchial repair. We successfully performed main bronchial repair in this traumatic patient with a congenital tracheal bronchus. We suggest that venovenous ECMO offers a good option for the treatment of bronchial rupture when adequate ventilation is not possible.

    Full Text Available Context - Uterine scar defects or scar niche are relatively common after cesarean delivery. An association has been observed between the severity of scar defect, also known as isthmocele, some gynecologic symptoms, and the risk of uterine scar dehiscence at the next delivery. It has been suggested that surgical repair of scar defect could improve the gynecological symptoms, but it remains unclear whether such surgery mends the uterine scar itself. Case Report - We report the case of a woman with uterine scar defect in whom laparoscopic repair significantly improved the gynecological symptoms without affecting the uterine scar, evaluated by hysterosonography. Conclusion - This case highlights the significant dearth of knowledge surrounding the diagnosis, consequences, and benefits of surgical repair of uterine scar defect after cesarean.

    Richter hernia (partial enterocele) is the protrusion and/or strangulation of only part of the circumference of the intestine's antimesenteric border through a rigid small defect of the abdominal wall. The first case was reported in 1606 by Fabricius Hildanus. The first definition of partial enterocele was given by August Gottlieb Richter in 1785. Sir Frederick Treves discriminated it from Littre hernia (hernia of the Meckel diverticulum). More often these hernias are diagnosed in the sixth and seventh decades of life. They comprise 10 per cent of strangulated hernias. Their common sites are the femoral ring, inguinal ring, and at incisional trauma. The most-often entrapped part of the bowel is the distal ileum, but any part of the intestinal tube may be incarcerated. These hernias progress more rapidly to gangrene than other strangulated hernias, and obstruction is less frequent. The gold standard technique for repair is the preperitoneal approach, followed by laparotomy and resection if perforation is suspected.

    Acute Achilles tendon ruptures is one of the commonest tendon injury of the foot and ankle. The management of this problem is still controversial. Treatment can be classified into non-surgical and surgical types. Surgical management can be subdivided into open repair, percutaneous with or without adjunct of arthroscopy. In compare with non-surgical management, surgical management will decrease the tendon re-rupture rate. However, the possible surgical complications including wound breakdown and sural nerve injury are still quite significant. Percutaneous repair technique has the advantage of less chance of wound breakdown, but the rate of tendon re-rupture is higher than that after open tendon repair, because the repair is usually weaker than that achieved in open repair. Lui have described an endoscopic assisted repair with the Krackow locking suture. However, the technique is complicated and six portal wounds are needed. A simpler way of applying the Krackow suture through the portal wound has been described for reattachment of Achilles tendon insertion after endoscopic calcaneoplasty. We describe a mini-open approach of Achilles tendon repair with the Krackow locking suture. By means of release of the medial edge of the investing fascia, the Achilles tendon can be mobilized easily and the Krackow locking suture can be applied through a 1.5cm medial wound. Hopefully, this can improve the strength of repair and maintaining the advantage of minimally invasive tendon repair.

    Full Text Available Retrospective analysis was performed on 30 patients of skull defect who underwent surgical repair. Intraoperative and postoperative curative effect was evaluated on those patients, and the results showed that the incidence rate of intraoperative dura mater defect (P = 0.001, early postoperative complications [new epilepsy (P = 0.035 and effusion (P = 0.021] and late postoperative complications [foreign body sensation (P = 0.035 and dizziness and headache (P = 0.050] in long-term skull defect group were all higher than those in control group. In conclusion, surgical repair of long-term skull defect incurring high risk and various complications will not be an ideal management. Therefore, early surgical treatment for skull defect is suggested. DOI: 10.3969/j.issn.1672-6731.2015.12.016

    To investigate whether operative factors are associated with risk of surgical site infection (SSI) after hernia repair. Retrospective cohort study. Patients Commercially insured enrollees aged 6 months-64 years with International Classification of Diseases, Ninth Revision, Clinical Modification procedure or Current Procedural Terminology, fourth edition, codes for inguinal/femoral, umbilical, and incisional/ventral hernia repair procedures from January 1, 2004, through December 31, 2010. SSIs within 90 days after hernia repair were identified by diagnosis codes. The χ2 and Fisher exact tests were used to compare SSI incidence by operative factors. A total of 119,973 hernia repair procedures were analyzed. The incidence of SSI differed significantly by anatomic site, with rates of 0.45% (352/77,666) for inguinal/femoral, 1.16% (288/24,917) for umbilical, and 4.11% (715/17,390) for incisional/ventral hernia repair. Within anatomic sites, the incidence of SSI was significantly higher for open versus laparoscopic inguinal/femoral (0.48% [295/61,142] vs 0.34% [57/16,524], P=.020) and incisional/ventral (4.20% [701/16,699] vs 2.03% [14/691], P=.005) hernia repairs. The rate of SSI was higher following procedures with bowel obstruction/necrosis than procedures without obstruction/necrosis for open inguinal/femoral (0.89% [48/5,422] vs 0.44% [247/55,720], P<.001) and umbilical (1.57% [131/8,355] vs 0.95% [157/16,562], P<.001), but not incisional/ventral hernia repair (4.01% [224/5,585] vs 4.16% [491/11,805], P=.645). The incidence of SSI was highest after open procedures, incisional/ventral repairs, and hernia repairs with bowel obstruction/necrosis. Stratification of hernia repair SSI rates by some operative factors may facilitate accurate comparison of SSI rates between facilities.

    Background The role of laparoscopic repair of ventral hernias remains incompletely defined. We hypothesize that laparoscopy, compared to open repair with mesh, decreases surgical site infection (SSI) for all ventral hernia types. Methods MEDLINE, EMBASE, and Cochrane databases were reviewed to identify studies evaluating outcomes of laparoscopic versus open repair with mesh of ventral hernias and divided into groups (primary or incisional). Studies with high risk of bias were excluded. Primary outcomes of interest were recurrence and SSI. Fixed effects model was used unless significant heterogeneity, assessed with the Higgins I-square (I2), was encountered. Results There were five and fifteen studies for primary and incisional cohorts. No difference was seen in recurrence between laparoscopic and open repair in the two hernia groups. SSI was more common with open repair in both hernia groups: primary (OR 4.17, 95%CI [2.03–8.55]) and incisional (OR 5.16, 95%CI [2.79–9.57]). Conclusions Laparoscopic repair, compared to open repair with mesh, decreases rates of SSI in all types of ventral hernias with no difference in recurrence. This data suggests that laparoscopic approach may be the treatment of choice for all types of ventral hernias. PMID:25294541

    Isolated tricuspid valve (ITV) operations are infrequent and the decision to operate is controversial. We report a series of ITV operations to outline the current disease status requiring this uncommon procedure with an emphasis on the results of tricuspid valve repair (TVr) versus replacement (TVR). Using our prospective cardiac surgery database, 57 patients who underwent ITV operations between 01/02-03/14 were identified. Median follow up time was 3.5 years [interquartile range (IQR), 0.8-6.7 years]. Fifty-seven patients underwent ITV surgery with a mean age of 54.4±14.9 yrs and 61% were women. Baseline characteristics were similar between patients who underwent TVr (n=18) or TVR (n=39). The etiologies of TV dysfunction were: ITV endocarditis 14/57 (25%), persistent TV regurgitation after left-sided valve surgery in 12/57 (21%), traumatic biopsies and iatrogenic injury from pacing leads in 11/57 (19%), orthotopic heart transplant 9/57 (16%), carcinoid syndrome 3/57 (5%), congenital 2/57 (5%) and idiopathic 5/57 (9%). Overall, 32/57 (56%) patients had prior heart surgery; of which 10/32 (31%) were TV procedures. Bioprosthetic prostheses were used in 34/39 (87%) patients. Of those who had repair, 11/18 (61%) had ring annuloplasty, 3/18 (17%) bicuspidization, and 3/18 (17%) De Vega annuloplasty and one had vegetectomy. Operative mortality was 5.1% (n=2) and 16.7% (n=3) for TVR and TVr groups, respectively (P=0.32), with an overall mortality rate of 8.6%. Postoperative complications included new onset renal failure in 6/39 (15%) of TVr and 2/18 (11%) of TVR (P=0.71) and there were no strokes. Overall survival rates and degree of residual RV dysfunction were similar for the two groups (both P=0.3). Five-year survival was 77% and 84% for TVr and TVR respectively (P=0.52). There was no difference in rates of recurrent tricuspid regurgitation for TVr and TVR (35.7% vs. 23.5%, respectively, P=0.4). ITV surgery is associated with improved but still relatively high

    Littre hernia is the protrusion of a Meckel diverticulum through a potential abdominal opening. Alexis de Littre (1700) reported ileal diverticula and attributed them to traction. August Gottlieb Richter (1785) defined them as preformed, and Johann Friedrich Meckel (1809) postulated their embryologic origin. Sir Frederic Treves (1897) distinguished between Littre and Richter hernia (partial enterocele). Embryologically, Meckel diverticulum is the persistent intestinal part of the omphaloenteric duct through which the midgut communicates with the umbilical vesicle until the fifth week. It is found at the antimesenteric border of the ileum, usually located 30 to 90 cm from the ileocecal valve, measuring 3 to 6 cm in length and 2 cm in diameter. Usual sites of Littre hernia are: inguinal (50%), umbilical (20%), and femoral (20%). Meckel diverticulum may be accompanied in the sac by the ileal loop to which it is attached; rarely, it may undergo incarceration or strangulation, necrosis, and perforation. In children, it is mostly found in umbilical hernias, and the diverticulum is more prone to adhere to the sac. Repair of Littre hernia consists of resection of the diverticulum and herniorraphy; in perforated cases, care must be taken to not contaminate the hernia field.

    Abdominal wall hernias are often diagnosed on clinical examination or encountered intraoperatively during an abdominoplasty. Traditional surgical techniques for abdominoplasty and umbilical hernia repair, when performed simultaneously, can potentially compromise the vascular supply to the umbilicus. The authors describe a simplified surgical technique for the correction of umbilical hernias in conjunction with abdominoplasty. This procedure avoids any fascial incisions immediately adjacent to the umbilicus, thereby maintaining a maximal blood supply to the umbilical stalk. Over a six-year period, 17 patients underwent the described procedure. None have had a recurrence of their hernia or umbilical necrosis, and the aesthetics of the umbilicus have been improved.

    Full Text Available Background: The purpose of this study was to investigate outcomes of surgical repair of esophageal atresia (EA or tracheoesophageal fistula (TEF in newborns, with respect to incidence of death and other complications in early or late operations. Methods: Charts of all 80 infants with EA/TEF, operated in Alzahra hospital (A tertiary hospital of Isfahan University of Medical Sciences from 2002 to 2004 were reviewed. Patients were designed in two groups as, primary and delayed repair groups. Patients demographics, frequency of associated anomalies, and details of management and outcomes were studied. Results: There were 48 male and 32 female patients with a frequency of 28(35% preterm infant and mean birth weight of 2473±595 g. Overall survival rate was 71.2%. Mortality rate in delayed repair group was significantly higher than the other one (22.5% vs. 6.3% but with matching, according to full term/preterm proportion, the significant differences were failed. Female sex and being preterm were the most powerful predictors of death (nearly odds ratio=7 for both. Conclusion: in this study mortality and complications rates are higher in delayed repair than early one, although our data proposed that in absence of sever life threatening anomalies the most important factor for death is gestational age and female sex, and primary repair is opposed to it. Although mortality rate and complications are equal in two strategies, with matching cases for being preterm, but primary repair stays the better choice due to economic considerations.

    Achilles tendon rupture is a serious injury for which the best treatment is still controversial. Its primary goal should be to restore normal length and tension, thus obtaining an optimal function. Tendon elongation correlates significantly with clinical outcome; lengthening is an important cause of morbidity and may produce permanent functional impairment. In this article, we review all factors that may influence the repair, including the type of surgical technique, suture material, and rehabilitation program, among many others. PMID:21966048

    Lumbar hernias are rare clinical entities that often pose a challenge for repair. Because of the surrounding anatomy, adequate surgical herniorraphy is often difficult. Minimally invasive surgery has become an option for these hernias. Herein, we describe two patients with lumbar hernias (one with a recurrent traumatic hernia and one with an incisional hernia). Both of these hernias were successfully repaired laparoscopically.

    The late outcome in 226 patients who survived surgical repair of aortic coarctation was assessed 15-30 years after operation. Twenty six patients died during the follow up mainly from causes related to surgical repair or to associated cardiovascular anomalies. The survival rates of patients operated on between the ages of four and 20 years are 97%, 97%, 92% at 10, 20, and 30 years after operation. For patients operated on after the age of 20 the corresponding rates are 93%, 85%, and 68%. This difference is statistically significant from the fifteenth year of follow up onwards. The survival of patients operated on before the age of 20 is not significantly different from that of a comparable general Italian population. Recoarctation occurred in only 8% of patients who had end to end anastomosis, whereas it occurred in 35% of those who had other types of operation. Two thirds of the patients were hypertensive at the last visit. The actuarial curve shows that blood pressure was normal in most patients 5-10 years after operation, but 30 years after coarctation repair only 32% of patients are expected to be normotensive. Thus early repair of aortic coarctation appears to improve long term survival. Intervention in older patients and when blood pressure is high seem to be the most important predictors of late hypertension. PMID:3593616

    Full Text Available BACKGROUND: In some patients, local surgery-related complications are diagnosed many years after surgery for aortic coarctation. The purposes of this study were: (1 to systematically evaluate asymptomatic adults after Dacron patch repair in childhood, (2 to estimate the formation rate of secondary thoracic aortic aneurysms (TAAs and (3 to assess outcomes after intravascular treatment for TAAs. METHODS: This study involved 37 asymptomatic patients (26 female and 11 male who underwent surgical repair of aortic coarctation in the childhood. After they had reached adolescence, patients with secondary TAAs were referred to endovascular repair. RESULTS: Follow-up studies revealed TAA in seven cases (19% (including six with the gothic type of the aortic arch and mild recoarctation in other six (16%. Six of the TAA patients were treated with stentgrafts, but one refused to undergo an endovascular procedure. In three cases, stengrafts covered the left subclavian artery (LSA, in another the graft was implanted distally to the LSA. In two individuals, elective hybrid procedures were performed with surgical bypass to the supraaortic arteries followed by stengraft implantation. All subjects survived the secondary procedures. One patient developed type Ia endoleak after stentgraft implantation that was eventually treated with a debranching procedure. CONCLUSIONS: The long-term course of clinically asymptomatic patients after coarctation patch repair is not uncommonly complicated by formation of TAAs (particularly in individuals with the gothic pattern of the aortic arch that can be treated effectively with stentgrafts. However, in some patients hybrid procedures may be necessary.

    Umbilical hernias present commonly during pregnancy secondary to increased intra-abdominal pressure. As a result, umbilical hernia incarceration or strangulation may affect pregnant females. The purpose of this study is to detail the operative management and 30-day outcomes of umbilical hernias in pregnant patients using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). All female patients undergoing umbilical hernia repair during pregnancy were identified within the ACS-NSQIP. Preoperative patient variables, intraoperative variables, and 30-day patient morbidity and mortality outcomes were investigated using a variety of statistical tests. A total of 126 pregnant patients underwent umbilical hernia repair from 2005 to 2014; 73 (58%) had incarceration or strangulation at the time of surgical intervention. The majority of patients (95%) underwent open umbilical hernia repair. Superficial surgical site infection was the most common morbidity in patients undergoing open umbilical hernia repair. Based on review of the ACS-NSQIP database, the incidence of umbilical hernia repair during pregnancy is very low; however, the majority of patients required repair for incarceration of strangulation. When symptoms develop, these hernias can be repaired with minimal 30-day morbidity to the mother. Additional studies are needed to determine the long-term recurrence rate of umbilical hernia repairs performed in pregnant patients and the effects of surgical intervention and approach on the fetus.

    Damage to the peripheral nervous system is surprisingly common and occurs primarily from trauma or a complication of surgery. Although recovery of nerve function occurs in many mild injuries, outcomes are often unsatisfactory following severe trauma. Nerve repair and regeneration presents unique clinical challenges and opportunities, and substantial contributions can be made through the informed application of biomedical engineering strategies. This article reviews the clinical presentations and classification of nerve injuries, in addition to the state of the art for surgical decision-making and repair strategies. This discussion presents specific challenges that must be addressed to realistically improve the treatment of nerve injuries and promote widespread recovery. In particular, nerve defects a few centimeters in length use a sensory nerve autograft as the standard technique; however, this approach is limited by the availability of donor nerve and comorbidity associated with additional surgery. Moreover, we currently have an inadequate ability to noninvasively assess the degree of nerve injury and to track axonal regeneration. As a result, wait-and-see surgical decisions can lead to undesirable and less successful "delayed" repair procedures. In this fight for time, degeneration of the distal nerve support structure and target progresses, ultimately blunting complete functional recovery. Thus, the most pressing challenges in peripheral nerve repair include the development of tissue-engineered nerve grafts that match or exceed the performance of autografts, the ability to noninvasively assess nerve damage and track axonal regeneration, and approaches to maintain the efficacy of the distal pathway and targets during the regenerative process. Biomedical engineering strategies can address these issues to substantially contribute at both the basic and applied levels, improving surgical management and functional recovery following severe peripheral nerve injury.

    2015-10-01

    Motor innervation of the face depends on the facial nerve for the mobility of the face, on the mandibular nerve, third branch of the trigeminal nerve, which gives the motor innervation of the masticator muscles, and the hypoglossal nerve for the tongue. In case of facial paralysis, the most common palliative surgical techniques are the lengthening temporalis myoplasty (the temporal is innervated by the mandibular nerve) and the hypoglossal-facial anastomosis. The aim of this work is to describe the surgical anatomy of these three nerves and the radiologic anatomy of the facial nerve inside the temporal bone. Then the facial nerve penetrates inside the parotid gland giving a plexus. Four branches of the facial nerve leave the parotid gland: they are called temporal, zygomatic, buccal and marginal which give innervation to the cutaneous muscles of the face. Mandibular nerve gives three branches to the temporal muscles: the anterior, intermediate and posterior deep temporal nerves which penetrate inside the deep aspect of the temporal muscle in front of the infratemporal line. The hypoglossal nerve is only the motor nerve to the tongue. The ansa cervicalis, which is coming from the superficial cervical plexus and joins the hypoglossal nerve in the submandibular area is giving the motor innervation to subhyoid muscles and to the geniohyoid muscle.

    Background Atrophy of rotator cuff muscles has been considered an irreversible phenomenon. The purpose of this study is to evaluate whether atrophy is truly irreversible after rotator cuff repair. Methods We measured supraspinatus muscle atrophy of 191 patients with full-thickness rotator cuff tears on preoperative magnetic resonance imaging and postoperative multidetector computed tomography images, taken at least 1 year after operation. The occupation ratio was calculated using Photoshop CS3 software. We compared the change between pre- and postoperative occupation ratios after modifying the preoperative occupation ratio. In addition, possible relationship between various clinical factors and the change of atrophy, and between the change of atrophy and cuff integrity after surgical repair were evaluated. Results The mean occupation ratio was significantly increased postoperatively from 0.44 ± 0.17 to 0.52 ± 0.17 (p atrophy (more than a 10% increase in occupation ratio) and 33 (17.3%) worsening (more than a 10% decrease). Various clinical factors such as age tear size, or initial degree of atrophy did not affect the change of atrophy. However, the change of atrophy was related to repair integrity: cuff healing failure rate of 48.5% (16 of 33) in worsened atrophy; and 22.2% (18 of 81) in improved atrophy (p = 0.007). Conclusions The supraspinatus muscle atrophy as measured by occupation ratio could be improved postoperatively in case of successful cuff repair. PMID:23467404

    Acute ruptures of the Achilles tendon affect the tendon's structural and mechanical properties. The long-term effects of surgical repair on these properties remain unclear. To evaluate effects of early mobilization versus traditional immobilization rehabilitation programs 2 years after surgical Achilles tendon repair, by comparing force-elongation and stress-strain relationships of the injured tendon to those of the uninjured tendon. A group of males with previous Achilles tendon rupture (n=18) and a group of healthy male controls (n=9) participated. Achilles tendon rupture group consisted of patients that had received early mobilization (n=9) and patients that had received traditional immobilization with a plaster cast (n=9). Comparisons of tendon structural and mechanical properties were made between Achilles tendon rupture and healthy control groups, and between the uninjured and injured sides of the two rehabilitation groups in Achilles tendon rupture group. Ultrasound was used to determine bilaterally tendon cross-sectional area, tendon resting length, and tendon elongation as a function of torque during maximal voluntary plantar flexion. From these data, Achilles tendon force-elongation and stress-strain relationships were determined. The Achilles tendon rupture group uninjured side was not different from healthy control group. Structural and mechanical parameters of the injured side were not different between the Achilles tendon rupture early mobilization and the immobilization groups. Compared to the uninjured side, the injured side showed a reduction in stress at maximal voluntary force, in Young's modulus and in stiffness. Two years post-surgical repair, the Achilles tendon mechanical properties had not returned to the uninjured contralateral tendon values. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Complete rupture of the hamstring tendons in the adult is a rare injury. This report discusses complete rupture of the hamstring tendons in nine patients treated by late operative repair. All patients were referred from outside centers for a second opinion after failed nonoperative treatment. The diagnosis was made quite easily on clinical grounds and was confirmed at surgery. Surgical treatment in all cases consisted of reattachment of the hamstring tendons to the origin on the ischium, and in all cases it was necessary to perform neurolysis of the sciatic nerve. Good results were achieved in all cases, at follow-up all patients were satisfied with the surgery.

    Trisomy 8 mosaicism is a relatively rare chromosomal abnormality and has extremely variable phenotype with a wide range of clinical manifestations. Although no well-defined criteria for cardiac surgical indications are available for patients with mosaic trisomy 8, we present a case of hypoplastic left heart syndrome with total anomalous pulmonary venous connection (TAPVC) in a neonate with mosaic trisomy 8. Although primary sutureless repair of TAPVC with concomitant bilateral pulmonary artery banding was performed successfully in this case, the indications for cardiac surgery in patients with mosaic trisomy 8 should be carefully individualized. The entire dialog with parents and family, including the process of informed consent, is of great importance.

  20. Surgical risk factors for recurrence in inguinal hernia repair – a review of the literature

    2017-04-01

    Full Text Available Despite all the progress made in inguinal hernia surgery driven by the development of meshes and laparoendoscopic operative techniques, the proportion of recurrent inguinal hernias is still from 12% to 13%. Recurrences can present very soon after primary inguinal hernia repair generally because of technical failure. However, they can also develop much later after the primary operation probably due to patient-specific factors. Supported by evidence-based data, this review presents the surgical risk factors for recurrent inguinal hernia after the primary operation. The following factors are implicated here: choice of operative technique and mesh, mesh fixation technique, mesh size, management of medial and lateral hernia sac, sliding hernia, lipoma in the inguinal canal, operating time, type of anesthesia, participation in a register database, femoral hernia, postoperative complications, as well as the center and surgeon volume. If these surgical risk factors are taken into account when performing primary inguinal hernia repair, a good outcome can be expected for the patient. Therefore, they should definitely be observed.

    Aortic coarctation is a common congenital cardiovascular defect, which can be diagnosed over a wide range of ages and with varying degrees of severity. Surgery has proven to be an effective treatment for the management of native aortic coarctation, and remains the treatment of choice in neonates. Balloon angioplasty with or without stenting has evolved rapidly over the past decade. Balloon angioplasty is the treatment of choice in children with re-coarctation, and currently available immediate results in native coarctation are similar with regards to gradient reduction as compared with surgery. However, both treatment options carry the risk of restenosis and aortic wall complications, especially after balloon angioplasty without stenting in native coarctation. On the other hand, stent implantation has shown excellent short-term results in both children beyond infancy and in adults with native coarctation. In patients with recurrent coarctation who are at high surgical risk, balloon angioplasty and stent repair offer a less invasive and equally effective method. Stent repair is preferred over balloon angioplasty in adults and outgrown children with a recurrent coarctation, as the risk for re-coarctation and aneurysm formation seems to be lower. Data with regard to long-term outcome after percutaneous treatment strategies are scarce. This review summarizes the current insights in the efficacy and safety of both surgical and transcatheter treatment options for aortic coarctation.

    Full Text Available Aim: To evaluate the outcome of definitive repair of anogenital injuries (AGI in child victims of acute sexual assault. settings and Design: It is a prospective study of emergency care provided to child victims of acute sexual assault at a tertiary care Pediatric Surgical Unit in Maharashtra, India. Material and Methods : Out of 25 children, who presented during January 2009-December 2010 with suspected sexual assault, five children (one male and four female, between 4-9 years of age, had incurred major AGI. These children underwent definitive repair and a diverting colostomy. Perineal pull-through was performed in the male child with major avulsion of rectum. One 4-year-old girl with intraperitoneal vaginal injury required exploratory laparotomy in addition. Results : The postoperative period and follow-up was uneventful in all our patients. Four out of five patients have excellent cosmetic and functional outcome with a follow-up of 2-4 years. Our continence results are 100%. Conclusion : Children with acute sexual assault need emergency care. To optimally restore the distorted anatomy, all major AGI in such children should be primarily repaired by an expert, conversant with a child′s local genital and perineal anatomy. Along with provision of comprehensive and compassionate medical care, prevention of secondary injuries should be the ultimate goal.

    Full Text Available Background Ventricular septal defects (VSD is one of the most frequent congenital cardiac malformations and cardiac conduction disorders are still one of the serious postoperative complications in this surgery. Objectives This study aimed to compare the incidence of conduction disorders with the use of continuous compared to interrupted suturing techniques in VSD surgical repair. Patients and Methods Previously recorded data of 231 patients who underwent surgical closure of VSD between January 2009 and January 2012 at the Rajaie cardiovascular medical and research center were retrospectively reviewed. VSD surgical repair was performed using continues suturing technique in group A patients (n = 163, 70.6% and interrupted suturing technique in group B patients (n = 68, 29.4%. Results The most common concomitant congenital anomaly was Tetralogy of Fallot (27.3%. Twenty-four (10.4% patients had intraoperative cardiac arrhythmia, including 19 (8.2% transient and 5 (2.2 % permanent arrhythmia. During their ICU stay, ventricular arrhythmia and complete heart block were observed in 34 (14.7% and 5 patients (2.2%, respectively. At the time of the last follow-up, incomplete right bundle branch block (RBBB, complete RBBB, RBBB with left anterior hemi-block, and complete heart block were identified in 84 (36.4%, 42 (18.2%, 29 (12.6%, and 5 patients (2.2%, respectively. The results revealed that group A patients were most likely to have had cardiac arrhythmias during their ICU stay and at the time of last follow-up (P < 0.001, while the intraoperative incidence of cardiac arrhythmia during surgery was not statistically significant between the two groups (P = 0.06. Conclusions In the absence of any statistical differences in the other risk factors between the two groups, the difference in the incidence of conduction disorders can be attributed to the type of suturing used during the procedure.

    Patients undergoing coronary artery bypass graft (CABG) procedures have higher incidence of difficult laryngoscopy and intubation than general surgery population. Accurate prediction of difficult laryngoscopy in CABG patients is desirable to reduce the hemodynamic response and myocardial oxygen requirements. Recently, thyromental height test (TMHT) has been proposed as one of the highly sensitive and specific bedside tests to predict difficult airway. We, in our prospective observational study, evaluated the accuracy of the TMHT in predicting difficult laryngoscopy. A total of 345 patients undergoing CABG of either sex, in the age group of 35-80 years, American Society of Anesthesiologists 111, undergoing CABG, were studied. Airway assessment was performed with modified Mallampati test with the addition of thyromental distance, sternomental distance, and TMHT. Intraoperatively, direct laryngoscopy was done in accordance with Cormack and Lehane grade of laryngoscopy. The preoperative data and laryngoscopic findings were used together to evaluate the accuracy of TMHT. The sensitivity, specificity, positive and negative predictive values of other three tests were calculated according to standard formula. A total of 345 patients were in the group with mean age of study population at 56.7 (standard deviation 9.1) years (35-80 years). This study showed that almost all tests had good specificity, but sensitivity was poor. However, sensitivity of TMHT was 75% with accuracy of 95%. Receiver operating characteristic curve analysis of TMHT-derived cutoff was 52.17 which increased sensitivity to 81.25% and specificity to 92.3%. TMHT had a higher sensitivity compared to other tests along with good positive and negative predictive value and a very high specificity.

    Mitral valve geometry is significantly altered secondary to left ventricular remodeling in non-ischemic and ischemic dilated cardiomyopathies. Since the extent of remodeling and asymmetry of dilatation of the ventricle differ significantly between individual patients, the valve geometry and tethering also differ. The study aim was to determine if mitral valve geometry has an impact on the efficacy of surgical repairs to eliminate regurgitation and restore valve closure in a validated experimental model. Porcine mitral valves (n = 8) were studied in a pulsatile heart simulator, in which the mitral valve geometry can be precisely altered and controlled throughout the experiment. Baseline hemodynamics for each valve were measured (Control), and the valves were tethered in two distinct ways: annular dilatation with 7 mm apical papillary muscle (PM) displacement (Tether 1, symmetric), and annular dilatation with 7 mm apical, 7 mm posterior and 7 mm lateral PM displacement (Tether 2, asymmetric). Mitral annuloplasty was performed on each valve (Annular Repair), succeeded by anterior leaflet secondary chordal cutting (Sub-annular Repair). The efficacy of each repair in the setting of a given valve geometry was quantified by measuring the changes in mitral regurgitation (MR), leaflet coaptation length, tethering height and area. At baseline, none of the valves was regurgitant. Significant leaflet tethering was measured in Tether 2 over Tether 1, but both groups were significantly higher compared to baseline (60.9 +/- 31 mm2 for Control versus 129.7 +/- 28.4 mm2 for Tether 1 versus 186.4 +/- 36.3 mm2 for Tether 2). Consequently, the MR fraction was higher in Tether 2 group (23.0 +/- 5.7%) than in Tether 1 (10.5 +/- 5.5%). Mitral annuloplasty reduced MR in both groups, but remnant regurgitation after the repair was higher in Tether 2. After chordal cutting a similar trend was observed with trace regurgitation in Tether 1 group at 3.6 +/- 2.8%, in comparison to 18.6 +/- 4

    We aimed to compare the effectiveness of experimental middle hernia defect repair in regard to the transverse and longitudinal positioning of anisotropic lightweight surgical mesh. The mechanical properties of fascial layers and surgical mesh DynaMesh(®)-PP Light were determined in two perpendicular directions under uniaxial tension. In 12 male Wistar rats, middle hernia defect was repaired by the sublay technique. In six animals, the mesh was positioned across (DLH group) and in the other six along (DLV group) the midline. At 6 months after implantation, mesh deformation, structural rearrangement, and repaired abdominal wall biomechanics were evaluated. Histological sections were stained with van Giesen and Mallory's trichrome. The anisotropic mechanical properties of the mesh and fascial layers coincided in the DLH group, but did not correspond to each other in the DLV group. In the DLV group, meshes were stretched in width by 11.4% and reduced in length by 12.7%. In all animals, the lower edge of the mesh was shifted to a defect area with margin hernia formation in two rats. Constant shear stress caused disproportional connective tissue formation. Repaired abdominal wall lost its natural elasticity. In the DLH group, the mesh deformation was minimal. Formed connective tissue was tightly associated with the anterior layer and did not differ from it in composition. The mechanical properties of repaired abdominal wall were close to those of the anterior layer. In prosthetic hernia repair, the mechanical properties of surgical mesh should correspond with those of the fascia being repaired. A mismatch of mechanical properties may result in implant deformation, abdominal wall biomechanics impairment, and recurrent herniation at the edges of the meshes.

    This report describes a case of cortical blindness that followed successful surgical repair of two stab wounds in the heart in a 29-year old Libyan man. The patient presented in a state of pre cardiac arrest (shock and low cardiac output status), following multiple chest stab wounds. Chest tube was immediately inserted. Surgery was urgently performed suturing the two wounds; in the root of the aorta and in the left ventricle, and haemostasis was secured. Cardiac arrest was successfully prevented. The patient recovered smoothly, but 24 hours later he declared total blindness. Ophtalmic and neurological examinations and investigations that included fundoscopy, Electroencephalograms (EEGs) and Computed Tomography Scans revealed no abnormalities, apart from absence of alpha waves in the EEGs. We diagnosed the case as cortical blindness and continued caring for the patient conservatively. Three days later, the patient regained his vision gradually and was discharged on the 7(th) postoperative day without any remarks.

    Background Monocusp reconstruction with a transannular patch (TAP) results in early improvement because it relieves residual volume hypertension during the immediate postoperative period. However, few reports have assessed the long-term surgical outcomes of this procedure. The purpose of the present study was to evaluate the mid-term surgical outcomes of tetralogy of Fallot (TOF) repair using monocusp reconstruction with a TAP. Methods Between March 2000 and March 2009, 36 patients with a TOF received a TAP. A TAP with monocusp reconstruction (group I) was used in 25 patients and a TAP without monocusp reconstruction (group II) was used in 11 patients. We evaluated hemodynamic parameters using echocardiography during the follow-up period in both groups. Results At the most recent follow-up echocardiography (mean follow-up, 8.2 years), the mean pulmonary valve velocities of the patients in group I and group II were 2.1±1.0 m/sec and 0.9±0.9 m/sec, respectively (p=0.001). Although the incidence of grade 3–4 pulmonary regurgitation (PR) was not significantly different between the two groups (group I: 16 patients, 64.0%; group II: 7 patients, 70.0%; p=0.735) during the follow-up period, the interval between the treatment and the incidence of PR aggravation was longer in group I than in group II (group I: 6.5±3.4 years; group II: 3.8±2.2 years; p=0.037). Conclusion Monocusp reconstruction with a TAP prolonged the interval between the initial treatment and grade 3–4 PR aggravation. Patients who received a TAP with monocusp reconstruction to repair TOF were not to progress to pulmonary stenosis during the follow-up period as those who received a TAP without monocusp reconstruction.

    Background Current inguinal hernia operations are generally based on anatomical considerations. Failures of such operations are due to lack of consideration of physiological aspects. Many patients with inguinal hernia are cured as a result of current techniques of operation, though factors that are said to prevent hernia formation are not restored. Therefore, the surgical physiology of inguinal canal needs to be reconsidered. Methods A retrospective study is describer of 200 patients operated on for inguinal hernia under local anaesthesia by the author's technique of inguinal hernia repair. Results The posterior wall of the inguinal canal was weak and without dynamic movement in all patients. Strong aponeurotic extensions were absent in the posterior wall. The muscle arch movement was lost or diminished in all patients. The movement of the muscle arch improved after it was sutured to the upper border of a strip of the external oblique aponeurosis (EOA). The newly formed posterior wall was kept physiologically dynamic by the additional muscle strength provided by external oblique muscle to the weakened muscles of the muscle arch. Conclusions A physiologically dynamic and strong posterior inguinal wall, and the shielding and compression action of the muscles and aponeuroses around the inguinal canal are important factors that prevent hernia formation or hernia recurrence after repair. In addition, the squeezing and plugging action of the cremasteric muscle and binding effect of the strong cremasteric fascia, also play an important role in the prevention of hernia. PMID:12697071

    2016-02-01

    Postoperative impairment of right ventricular (RV) systolic function can appear after surgical repair of complex congenital heart defects, such as tetralogy of Fallot; it is caused by chronic volume and/or pressure overload due to pulmonary regurgitation and/or stenosis. RV dysfunction is strongly associated with prognosis in these patients. Cardiac magnetic resonance imaging is the gold standard for quantification of RV volumes and ejection fraction in patients with congenital heart diseases; however, it is costly and is not widely available. Echocardiography is the imaging modality that is most available and most frequently used to assess RV systolic function. However, RV ejection fraction cannot be measured accurately by standard two-dimensional echocardiography because of its pyramidal shape. Surrogate parameters of RV systolic function are mostly used in routine practice. New techniques of two-dimensional strain and three-dimensional quantification of RV volumes and ejection fraction have been developed in recent years. The aim of this article is to show the pertinence of each variable of RV systolic function measured by echocardiography in patients with repaired congenital heart disease and residual chronic RV overload.

    The objective structured clinical examination (OSCE) can be used to evaluate the Accreditation Council for Graduate Medical Education Core Competencies of Professionalism and Interpersonal and Communication Skills. The aim of this study was to describe general surgery resident performance on a "difficult conversation" OSCE. In this prospective study, junior and senior residents participated in a 2-station OSCE. Junior stations involved discussing operative risks and benefits and breaking bad news. Senior stations involved discussing goals of care and discussing transition to comfort measures only status. Residents completed post-OSCE checklist and Likert-based self-evaluations of experience, comfort, and confidence. Trained standardized patients (SPs) evaluated residents using communication skill-based checklists and Likert-based assessments. Pearson correlation coefficients were determined between self-assessment and SP assessment. Mann-Whitney U tests were conducted between junior and senior resident variables, using α = 0.05. There were 27 junior residents (age 28.1 ± 1.9 years [29.6% female]) and 27 senior residents (age 32.1 ± 2.5 years [26.9% female]). The correlation of self-assessment and SP assessment of overall communication skills by junior residents was -0.32 on the risks and benefits case and 0.07 on the breaking bad news case. The correlation of self-assessment and SP assessment of overall communication skills by senior residents was 0.30 on the goals of care case and 0.26 on the comfort measures only case. SP assessments showed that junior residents had higher overall communication skills than senior residents (p = 0.03). Senior residents perceived that having difficult conversations was more level appropriate (p skills are correlated, and that skills-based training is needed across all residency levels. This well-received method may be used to observe, document, and provide resident feedback for these important skills. © 2014 Published by

    An in vitro study was conducted to determine the feasibility of using a new range of light-activated surgical adhesives for incision repair in a wide range of tissue types. Biodegradable polymer membranes of controlled porosity were fabricated with poly(L-lactic-co-glycolic acid) (PLGA) and salt particles using a solvent-casting and particulate- leaching technique. The porous membranes were doped with protein solder composed of 50%(w/v) bovine serum albumin solder and 0.5 mg/ml indocyanine green (ICG) dye mixed in deionized water. Tissue incisions were repaired using the surgical adhesive in conjunction with an 805-nm diode laser. Nine organs were tested ranging from skin to liver to the small intestine, as well as the coronary, pulmonary, carotid, femoral and splenetic arteries. Acute breaking strengths were measured and the data were analyzed by Student's T-test. Repairs formed on the small intestine were most successful followed by spleen, atrium, kidney, muscle and skin. The strongest vascular repairs were achieved in the carotid artery and femoral artery. The new surgical adhesive could possibly be used as a simple and effective method to stop bleeding and repair tissue quickly in an emergency situation, or as a substitute to mechanical staples or sutures in many clinical applications.

    Pectus excavatum is relatively common congenital chest deformity that is often accompanied by physical and psychological impairment. The surgical methods for pectus excavatum repair are the subject of some controversy. We review our experience using a procedure in which the introduction of exogenous material is unnecessary. From July 1993 to March 2008, 113 patients underwent surgical repair of pectus excavatum. Sterno-costal elevation was adopted for 102 patients, including all of the paediatric patients and most of the adults. Sternal turnover was employed for 11 adult patients with severe asymmetric deformities. In sterno-costal elevation, a section of the third or fourth to the seventh costal cartilages as well as the lower tip of the sternum below the sixth cartilage junction are resected, and all of the cartilage stumps are re-sutured to the sternum. The secured ribs generate 0.5-10 kg of tension, pulling the sternum bilaterally, such that the resultant force causes the sternum to rise anteriorly. These forces are sufficient to correct the deformities and to prevent flail chest. In sternal turnover, the sternum is cut at the third intercostal space. The lower part of the sternum is turned over and fixed to the upper sternum with an overlap of 1cm. Sections of the third to the seventh rib cartilages are resected and affixed in the same fashion as in sterno-costal elevation. There were no operative deaths, and in all cases the deformities were corrected satisfactorily. Ninety-nine patients (88%) were graded as Excellent, and the remaining 14 (12%) were graded Good. None of the patients developed any life-threatening complications. No patient reported residual pain. No re-operations were required for any reasons. The patients resumed daily activities of all types, including contact sports, within 3 months after surgery. We believe that morbidity is one of the most important factors to be considered in operative invasions. Our technique represents a less

    Full Text Available One of the causes of non-healing periapical pathosis in endodontically treated tooth is root perforation. This can occur pathologically by resorption and caries, iatrogenically during endodontic therapy (zip, strip, furcal perforations. Root perforation results in bacterial contamination, periradicular tissue injury, inflammation, and bone resorption. The purpose of this case report is to describe endodontic retreatment and surgical management of a longstanding periapical lesion on maxillary lateral incisor, associated with perforation and osseous defects using mineral trioxide aggregate (MTA. Although the majority of bone support and root dentin was damaged, an attempt was made to repair the defect and restore the tooth. After the surgical intervention and root canal treatment, the perforation was subsequently sealed with MTA. Later, the root was reinforced with composites and the tooth was restored with direct veneer. Conclusion: Four-and-a-half year (54 months recall examination showed no evidence of periodontal breakdown, no symptoms of further deterioration, and complete healing of periradicular lesions when examined by radiography. This case report presents a treatment strategy that could improve the healing process and beneficial outcomes for patients with perforation and osseous defect.

    Full Text Available Many multiparous women complain of protruded and pendulous abdomens and vaginal outlet relaxation which affect their sexual relationships with their male partners. This study included 47 patients who had these complaints. Some of these patients were working outside the homes and all were mothers of 2-5 children. Due of their home and job responsibilities, they did not have enough time or money for multiple surgeries in more than one session. Material and Methods: The age of these patients was 26-54 years and all patients had poor skin elasticity, pendulous excess subcutaneous fat and skin below the level of the anterior vulvar commissure, and a lax musculoaponeurotic anterior abdominal wall. Also, all patients had a relaxed vaginal outlet and 32 patients had rectocele. Careful perioperative assessment and management was done for each patient to ensure fitness for the long operation and to avoid complications. The combined surgical session consisted of two steps: abdominoplasty and posterior vaginal repair. All the patients were kept in the hospital for two days and they returned to their usual routines in the third week after surgery, and they resumed their sexual relationships with their male partners in the sixth week after surgery. Results: There were no serious complications and this approach was convenient for the patients and their families. The recovery time of the combined surgical session was the same as that of just abdominoplasty, and significantly less than the sum of the recovery periods if the two surgeries had been performed in two sessions. The cost of the combined surgical session was significantly less than doing the surgeries in two sessions. All the patients had significant improvement in their sexual relationships

    Objective This study aimed to report our experiences with surgical repair in patients of all ages with persistent truncus arteriosus. Methods From July 2004 to July 2014, 50 consecutive patients with persistent truncus arteriosus who underwent anatomical repair were included in the retrospective review. Median follow-up time was 3.4 years (range, 3 months to 10 years). Results Fifty patients underwent anatomical repair at a median age of 19.6 months (range, 20 days to 19.1 years). Thirty patients (60%) were older than one year. The preoperative pulmonary vascular resistance and mean pulmonary artery pressure were 4.1±2.1 (range, 0.1 to 8.9) units.m2 and 64.3±17.9 (range, 38 to 101) mmHg, respectively. Significant truncal valve regurgitation was presented in 14 (28%) patients. Hospital death occurred in 3 patients, two due to pulmonary hypertensive crisis and the other due to pneumonia. Three late deaths occurred at 3, 4 and 11 months after surgery. The actuarial survival rates were 87.7% and 87.7% at 1 year and 5 years, respectively. Multivariate analysis identified significant preoperative truncal valve regurgitation was a risk factor for overall mortality (odds ratio, 7.584; 95%CI: 1.335–43.092; p = 0.022). Two patients required reoperation of truncal valve replacement. One patient underwent reintervention for conduit replacement. Freedom from reoperation at 5 years was 92.9%. At latest examination, there was one patient with moderate-to-severe truncal valve regurgitation and four with moderate. Three patients had residual pulmonary artery hypertension. All survivors were in New York Heart Association class I-II. Conclusions Complete repair of persistent truncus arteriosus can be achieved with a relatively low mortality and acceptable early- and mid-term results, even in cases with late presentation. Significant preoperative truncal valve regurgitation remains a risk factor for overall mortality. The long-term outcomes warrant further follow-up. PMID:26752522

    OBJECTIVES. Cleft lip palate is congenital growth disease with unknown etiology, probably linked to both genetically and external causes. The aim of this work consists in presenting the effects of these diseases on cranio facial growth and the surgical protocols described in literature. MATERIALS AND METHODS. The literature review articles conducted by Medline ranged from 1998 to 2011 have been selected. The key words of the research were "cleft lip palate", "cleft lip palate facial growth", "cleft lip palate surgery". The inclusion criteria were articles that analyzed surgical protocols and the growth of unilateral lip and palate clefts, the timing repair of lip, palate and alveolus. We excluded case reports, studies without control group in the sample and the other types of publication as thesis or conference presentation. 60 articles had the selection criteria of the research. RESULTS. The cleft lip and palate is one of the most common birth defects that needs long rehabilitation between birth and adulthood. Several authors have presented surgical protocols and timing. The effects of these diseases on cranio facial growth and the importance of the early intervention have been described. CONCLUSIONS. The review describes the main surgical protocols and treatment strategies of the unilateral lip and palate clefts. The review discusses how surgery effects the midfacial skeletal growth. Studies agree that the palate repair is the main cause of the maxilla growth disturbances. About the timing of palate repair in the unilateral clefts it can be concluded that most studies found no difference between one or two stages palate repair techniques for the midfacial growth. Also from the research, studies agree that delayed hard palate repair has more positive effects on maxillary growth than that of early hard palate repair. Nevertheless good results, delayed hard palate repair technique is abandoned by many hospital centres because of worse speech outcome. The best

    The surgical benefit of minimally invasive tendo Achilles repair (n = 25) with early weight-bearing mobilisation after rupture of the tendo Achilles was compared with operative treatment using an open technique (n = 34) with full weight-bearing after 8 weeks of surgical repair. The minimally invasive technique provided no evidence of wound problems and a functional benefit from early weight-bearing mobilisation. However, we noted that increased post-operative morbidity in terms of wound infection (n = 7) leading to delayed wound healing and wound pain requiring opiate-based analgesia post-operatively in the open repair group may have an additional impact on the patients and health care providers. This study showed that the mini-invasive open surgical repair of the Achilles tendon with the Achillon instrument and early weight-bearing mobilisation in an orthosis for the accelerated rehabilitation may offer cost-effectiveness and less financial burden on the health care provider in terms of associated nursing and physiotherapy costs.

    Introduction Due to late complications associated with the use of conventional prosthetic heart valves, several centers have advocated aortic valve repair and/or valve sparing aortic root replacement for patients with aortic valve insufficiency, in order to enhance late survival and minimize adverse postoperative events. Methods From March/2012 thru March 2015, 37 patients consecutively underwent conservative operations of the aortic valve and/or aortic root. Mean age was 48±16 years and 81% were males. The aortic valve was bicuspid in 54% and tricuspid in the remaining. All were operated with the aid of intraoperative transesophageal echocardiography. Surgical techniques consisted of replacing the aortic root with a Dacron graft whenever it was dilated or aneurysmatic, using either the remodeling or the reimplantation technique, besides correcting leaflet prolapse when present. Patients were sequentially evaluated with clinical and echocardiographic studies and mean follow-up time was 16±5 months. Results Thirty-day mortality was 2.7%. In addition there were two late deaths, with late survival being 85% (CI 95% - 68%-95%) at two years. Two patients were reoperated due to primary structural valve failure. Freedom from reoperation or from primary structural valve failure was 90% (CI 95% - 66%-97%) and 91% (CI 95% - 69%-97%) at 2 years, respectively. During clinical follow-up up to 3 years, there were no cases of thromboembolism, hemorrhage or endocarditis. Conclusions Although this represents an initial series, these data demonstrates that aortic valve repair and/or valve sparing aortic root surgery can be performed with satisfactory immediate and short-term results.

    Purpose: To evaluate and compare MR and US findings in an unselected group of patients with 1-3 year-old surgically repaired complete ruptures of the Achilles tendon. Material and Methods: Thirteen patients with complete Achilles tendon rupture underwent clinical, MR and US examinations. The average time interval from rupture to postoperative imaging was 18 months. Results: The cross-sectional area of a postoperative tendon was 4.2 times that of the unaffected side. The shape of the operated tendon was more rounded than the unaffected side and it had irregular margins both in MR imaging and in US examination. In 4 of 13 cases an intratendinous area of intermediate to high signal intensity on proton density- and T2-weighted images was seen on MR. The size of this area varied from 4 to 18% of the cross-sectional tendon area. Two patients with the largest intratendinous area had poor clinical outcome. On US the tendon had mixed echogenicity in all cases and the tendon bands were thinner and shorter than normal. Comparison of dimension between MR and US revealed that in a.p. dimension the correlation was good (r=0.87, p=0.001), but in transversal width there was no significant correlation (r=0.58, p=0.06). Conclusion: The increased size and round irregular area of the operated Achilles tendon rupture was well detected by both MR and US, but intratendinous lesions were seen only by MR. (orig.).

    Surgical-site infections (SSIs) are associated with an increased duration of hospital stay, poorer quality of life, and an marked increase in cost to the hospital. Lapses in compliance with aseptic principles are a substantial risk factor for SSI, which may be attributable to distractions such as noise during the operation. The aims of this study were to assess whether noise levels in the operating room are associated with the development of SSI and to elucidate the extent to which these levels affect the financial burden of surgery. Prospective data collection from elective, day-case male patients undergoing elective hernia repairs was undertaken. Patients were included if they were fit and at low risk for SSI. Sound levels during procedures was measured via a decibel meter and correlated with the incidence of SSI. Data analysis was performed with IBM SPSS (IBM, Armonk, NY). Noise levels were substantially greater in patients with SSI from time point of 50 minutes onwards, which correlated to when wound closure was occurring. Additional hospital costs for these patients were £243 per patient based on the National Health Service 2013 reference costing. Decreasing ambient noise levels in the operating room may aid in reducing the incidence of SSIs, particularly during closure, and decrease the associated financial costs of this complication.

  8. Delayed peripheral nerve repair: methods, including surgical ′cross-bridging′ to promote nerve regeneration

    Full Text Available Despite the capacity of Schwann cells to support peripheral nerve regeneration, functional recovery after nerve injuries is frequently poor, especially for proximal injuries that require regenerating axons to grow over long distances to reinnervate distal targets. Nerve transfers, where small fascicles from an adjacent intact nerve are coapted to the nerve stump of a nearby denervated muscle, allow for functional return but at the expense of reduced numbers of innervating nerves. A 1-hour period of 20 Hz electrical nerve stimulation via electrodes proximal to an injury site accelerates axon outgrowth to hasten target reinnervation in rats and humans, even after delayed surgery. A novel strategy of enticing donor axons from an otherwise intact nerve to grow through small nerve grafts (cross-bridges into a denervated nerve stump, promotes improved axon regeneration after delayed nerve repair. The efficacy of this technique has been demonstrated in a rat model and is now in clinical use in patients undergoing cross-face nerve grafting for facial paralysis. In conclusion, brief electrical stimulation, combined with the surgical technique of promoting the regeneration of some donor axons to ′protect′ chronically denervated Schwann cells, improves nerve regeneration and, in turn, functional outcomes in the management of peripheral nerve injuries.

    Full Text Available Introduction: At the initial consultation, the speech-language pathologist and audiologist may consider possible diagnostic hypotheses based on the child's history and the parents' complaint. Aim: To investigate the association of hearing complaints with the findings obtained in the conventional audiologic assessment in children with cleft lip and palate. Retrospective study. Methods: We analyzed medical charts of 1000 patients with cleft lip and palate who underwent surgical repair between 1988 and 1995 at a mean age of 6 years 8 months. We excluded charts with records of inconsistent audiological responses and charts with missing data for any of the audiologic evaluations considered. Thus, the sample consisted of 393 records. Results: Two hundred thirty-nine patients presented hearing loss in one or both ears, but only 3.8% reported hearing complaints. The most frequent were otorrhea followed by otalgia. There was no statistical significance between the complaint and gender (p = 0.26 nor between the complaint and hearing loss (p = 0.83. Conclusion: This study showed no association between the hearing complaint and the conventional audiologic assessment.

    Background Long-term follow-up data concerning isolated tricuspid valve pathology after replacement or reconstruction is limited. Current American Heart Association guidelines equally recommend repair and replacement when surgical intervention is indicated. Our aim was to investigate and compare operative mortality and long-term survival in patients undergoing isolated tricuspid valve repair surgery versus replacement. Material/Methods Between 1995 and 2011, 109 consecutive patients underwent surgical correction of tricuspid valve pathology at our institution for varying structural pathologies. A total of 41 (37.6%) patients underwent tricuspid annuloplasty/repair (TAP) with or without ring implantation, while 68 (62.3%) patients received tricuspid valve replacement (TVR) of whom 36 (53%) were mechanical and 32 (47%) were biological prostheses. Results Early survival at 30 days after surgery was 97.6% in the TAP group and 91.1% in the TVR group. After 6 months, 89.1% in the TAP group and 87.8% in the TVR group were alive. In terms of long-term survival, there was no further mortality observed after one year post surgery in both groups (Log Rank p=0.919, Breslow p=0.834, Tarone-Ware p=0.880) in the Kaplan-Meier Survival analysis. The 1-, 5-, and 8-year survival rates were 85.8% for TAP and 87.8% for TVR group. Conclusions Surgical repair of the tricuspid valve does not show survival benefit when compared to replacement. Hence valve replacement should be considered generously in patients with reasonable suspicion that regurgitation after repair will reoccur. PMID:28236633

    The purpose of this study is to describe our technique of central slip repair using the Mitek bone anchor and to evaluate the treatment outcome. Eight digits in eight patients were reconstructed using the bone anchor: three little fingers, two middle fingers, two index fingers and one ring finger. There were two immediate and six delayed repairs (range from one day to eight months). Four patients had pre-operative intensive splinting and physiotherapy to restore passive extension of the proximal interphalangeal joint prior to central slip reconstruction. All patients have made good progress since surgery. No patient requires a second procedure and none of the bone anchors have dislodged or loosened. We conclude that the Mitek bone anchor is a reliable technique to achieve soft tissue to bone fixation in central slip avulsion injuries. We recommend that this technique be considered as a treatment option for patients requiring surgical repair.

    Full Text Available Anastomotic stricture (AS and recurrent tracheoesophageal fistula (TEF are two complications of surgical repair of esophageal atresia (EA. Therapeutic endoscopic modalities include stenting, tissue glue, and clipping for TEF and endoscopic balloon dilation bougienage and stenting for esophageal strictures. We report herein a two-month infant with both EA and TEF who benefited from a surgical repair for EA, at the third day of life. Two months later he experienced deglutition disorders and recurrent chest infections. The esophagogram showed an AS and a TEF confirmed with blue methylene test at bronchoscopy. A partially covered self-expanding metal type biliary was endoscopically placed. Ten weeks later the stent was removed. This allows for easy passage of the endoscope in the gastric cavity but a persistent recurrent fistula was noted. Instillation of contrast demonstrated a fully dilated stricture but with a persistent TEF. Then we proceeded to placement of several endoclips at the fistula site. The esophagogram confirmed the TEF was obliterated. At 12 months of follow-up, he was asymptomatic. Stenting was effective to alleviate the stricture but failed to treat the TEF. At our knowledge this is the second case of successful use of endoclips placement to obliterate recurrent TEF after surgical repair of EA in children.

    Full Text Available ABSTRACT Introduction Treatment of hydrocephalus is accomplished primarily through a ventricular-peritoneal shunt (VPS. This study aims to describe the application of retrograde ventricle-sinus shunt (RVSS in patients with hydrocephalus after surgical treatment of myelomeningocele. Method A prospective, randomized and controlled pilot study. We consecutively enrolled 9 patients with hydrocephalus after surgical repair of myelomeningocele from January 2010 to January 2012. These patients underwent elective RVSS or VPS. Five underwent RVSS and 4 underwent VPS. Patients were followed for one year with quarterly evaluations and application of transcranial Doppler. Results RVSS group showed outcomes similar to those of VPS group. Doppler revealed significant improvement when comparing preoperative to postoperative period. RVSS group had significantly higher cephalic perimeter than VPS group. Neuropsychomotor development, complications and subjective outcomes did not differ between groups. Conclusion RVSS shunt is viable; it is an alternative option for the treatment of hydrocephalus.

    Andrew Y Lee

    Full Text Available PURPOSE: To evaluate the efficacy of percutaneous balloon dilation of biliary-enteric anastomotic strictures resulting from surgical repair of laparoscopic cholecystectomy-related bile duct injuries. MATERIAL AND METHODS: A total of 61 patients were referred to our institution from 1995 to 2010 for treatment of obstruction at the biliary-enteric anastomosis following surgical repair of laparoscopic cholecystectomy-related bile duct injuries. Of these 61 patients, 27 underwent surgical revision upon stricture diagnosis, and 34 patients were managed using balloon dilation. Of these 34 patients, 2 were lost to follow up, leaving 32 patients for analysis. The primary study objective was to determine the clinical success rate of balloon dilation of biliary-enteric anastomotic strictures. Secondary study objectives included determining anastomosis patency, rates of stricture recurrence following treatment, and morbidity. RESULTS: Balloon dilation of biliary-enteric anastomotic strictures was clinically successful in 21 of 32 patients (66%. Anastomotic stricture recurred in one of 21 patients (5% after an average of 13.1 years of follow-up. Patients who were unsuccessfully managed with balloon dilation required significantly more invasive procedures (6.8 v. 3.4; p = 0.02 and were left with an indwelling biliary catheter for a significantly longer period of time (8.8 v. 2.0 months; p = 0.02 than patients whose strictures could be resolved by balloon dilation. No significant differences in the number of balloon dilations performed (p = 0.17 or in the maximum balloon diameter used (p = 0.99 were demonstrated for patients with successful or unsuccessful balloon dilation outcomes. CONCLUSION: Percutaneous balloon dilation of anastomotic biliary strictures following surgical repair of laparoscopic cholecystectomy-related injuries may result in lasting patency of the biliary-enteric anastomosis.

    To understand perspectives of local health providers on the social reintegration of patients who have undergone fistula repair in the eastern Democratic Republic of Congo. In a qualitative study, semi-structured individual interviews were conducted with patient-care professionals working with women with fistula at HEAL Africa Hospital (Goma) and Panzi Hospital (Bukavu) between June and August 2011. The interviews were transcribed and themes elicited through manual coding. Overall, 41 interviews were conducted. Successful surgical repair was reported to be the most important factor contributing to patients' ability to lead a normal life by all providers. Family acceptance-especially from the husband-was deemed crucial for reintegration by 39 (95%) providers, and 29 (71%) believed this acceptance was more important than the ability to work. Forty (98%) providers felt that, on the basis of African values, future childbearing was key for family acceptance. Because of poor access and the high cost of cesarean deliveries, 28 (68%) providers were concerned about fistula recurrence. Providers view postsurgical childbearing as crucial for social reintegration after fistula repair. However, cesarean deliveries are costly and often inaccessible. More work is needed to improve reproductive health access for women after fistula repair. Copyright © 2015 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

    To investigate the impacts of delayed repairs of a supraspinatus tendon tear on the supraspinatus muscle, we used an animal model data from two previously published studies in which one supraspinatus (SSP) tendon was detached. In one cohort, the rabbits were killed in groups of 10 at 4, 8, and 12 weeks. In the other cohort, a repair was done at these time points, 12 rabbits each, and the animals killed were 12 weeks later. SSP fossa volume (Muscle belly plus extramuscular fat [e-fat] volume), percentage of intramuscular fat (i-fat), and muscle tissue volume (muscle belly volume minus i-fat), as well as CT determination of e-fat and i-fat of both cohorts, were compared. Fossa volume increased (p Muscle belly and muscle tissue volumes did not increase after repair (p > 0.05), but early repair prevented further volume losses, a fact not seen after 8 and 12 weeks delay of repair. No reversal of e-fat or of i-fat occurred, in fact i-fat almost doubled after 4 weeks delay of repair (p fat results. We conclude that early repair prevented loss of muscle belly and muscle tissue volumes, but that it has no positive influence on fat accumulation. © 2014 Orthopaedic Research Society.

    Full Text Available Aim. To evaluate in-hospital and long-term results of surgical treatment of patients with infective endocarditis of the tricuspid valve, to compare the effectiveness of valve repair and valve replacement techniques, and to identify risk factors of mortality and reoperations. Materials and methods. 31 surgical patients with tricuspid valve infective endocarditis were evaluated. Patients were divided into 2 groups. In Group 1 (n = 14 repairs of the tricuspid valve were performed, in Group 2 (n = 17 patients had undergone tricuspid valve replacements. Epidemiological, clinical, microbiological and echocardiographic data were studied. Methods of comparative analysis, the Kaplan–Meier method, and Cox risk models were applied. Results. The most common complication of in-hospital stay was atrioventricular block (17.7% of cases in Group 2. In Group 1, this type of complication was not found. Hospital mortality was 7.14% in Group 1, and 0% in Group 2. Long-term results have shown the significant reduction of heart failure in general cohort and in both groups. In Group 1 the severity of heart failure in the long term was less than in Group 2. No significant differences in the severity of tricuspid regurgitation were found between the groups. In 7-year follow up no cases of death were registered in Group 1. Cumulative survival rate in Group 2 within 60 months was 67.3 ± 16.2%. No reoperations were performed in patients from Group 1. In Group 2, the freedom from reoperation within 60 months was 70.9 ± 15.3%. Combined intervention was found as predictor of postoperative mortality. Prosthetic valve endocarditis was identified as risk factor for reoperation. Conclusion. Valve repair and valve replacement techniques of surgical treatment of tricuspid valve endocarditis can provide satisfactory hospital and long-term results. Tricuspid valve repair techniques allowed reducing the incidence of postoperative atrioventricular block. In the long-term, patients

    Rhegmatogenous retinal detachments are associated with cytomegalovirus (CMV) retinitis and the use of the ganciclovir intraocular device. Pars plana vitrectomy with silicone oil tamponade is the preferred technique to repair such detachments. The authors describe the use of pneumatic retinopexy as part of a treatment strategy in the management of multiple retinal detachments in a patient with CMV retinitis treated with ganciclovir implants. Pneumatic retinopexy may benefit patients when the causative retinal break is superior and is located in an area of retina uninvolved with CMV infection, because it can be used to delay surgical intervention.

  6. Predictive factors for difficult mask ventilation in the obese surgical population [v1; ref status: indexed, http://f1000r.es/4i9

    2014-10-01

    Full Text Available Background Difficult Mask Ventilation (DMV, is a situation in which it is impossible for an unassisted anesthesiologist to maintain oxygen saturation >90% using 100% oxygen and positive pressure ventilation to prevent or reverse signs of inadequate ventilation during mask ventilation.  The incidence varies from 0.08 – 15%. Patient-related anatomical features are by far the most significant cause.  We analyzed data from an obese surgical population (BMI> 30 kg/m2 to identify specific risk and predictive factors for DMV. Methods Five hundred and fifty seven obese patients were identified from a database of 1399 cases associated with preoperative airway examinations where mask ventilation was attempted. Assessment of mask ventilation in this group was stratified by a severity score (0-3, and a step-wise selection method was used to identify independent predictors.  The area under the curve of the receiver-operating-characteristic was then used to evaluate the model’s predictive value. Adjusted odds ratios and their 95% confidence intervals were also calculated. Results DMV was observed in 80/557 (14% patients. Three independent predictive factors for DMV in obese patients were identified: age 49 years, short neck, and neck circumference  43 cm. In the current study th sensitivity for one factor is 0.90 with a specificity 0.35. However, the specificity increased to 0.80 with inclusion of more than one factor. Conclusion According to the current investigation, the three predictive factors are strongly associated with DMV in obese patients. Each independent risk factor alone provides a good screening for DMV and two factors substantially improve specificity. Based on our analysis, we speculate that the absence of at least 2 of the factors we identified might have a significant negative predictive value and can reasonably exclude DMV, with a negative likelihood ratio 0.81.

    We present our surgical technique and clinical outcome of the surgical repair of pectus excavatum using the DualMesh 2-mm Gore-Tex, in 21 young adults. The main symptom was the exercise limitation in 15 patients. There were no postoperative complications and excellent cosmetic results were achieved. We can confirm that DualMesh seems to be the ideal material to support the sternum in its corrected position. Its advantages are the strength to stabilize well the chest wall, the quality to be detached easily from the pericardial surface even in the case of urgent median sternotomy due to its particular surfaces, the resistance to infection and the ability to be left in place permanently.

    Full Text Available Articular cartilage damage in the young adult knee, if left untreated, it may proceed to degenerative osteoarthritis and is a serious cause of disability and loss of function. Surgical cartilage repair of an osteochondral defect can give the patient significant relief from symptoms and preserve the functional life of the joint. Several techniques including bone marrow stimulation, cartilage tissue based therapy, cartilage cell seeded therapies and osteotomies have been described in the literature with varying results. Established techniques rely mainly on the formation of fibro-cartilage, which has been shown to degenerate over time due to shear forces. The implantation of autologous cultured chondrocytes into an osteochondral defect, may replace damaged cartilage with hyaline or hyaline-like cartilage. This clinical review assesses current surgical techniques and makes recommendations on the most appropriate method of cartilage repair when managing symptomatic osteochondral defects of the knee. We also discuss the experience with the technique of autologous chondrocyte implantation at our institution over the past 11 years.

    Full Text Available Obiective: To assess the degree of satisfaction of women undergoing surgical repair of prolapse, compared with the clinical and urodynamic findings. Materials and Methods: 72 women hospitalized for pelvic organ prolapse (POP were enrolled in this prospective study. Patients underwent clinical evaluation and urodynamic study before and 4 months after POP repair. Women were assessed for urinary symptoms by micturition diary and patient perception of intensity of urgency scale. Women were also questioned about defecation and sexual life. POP repair was performed in all cases without the use of a mesh. Subjective evaluation was performed by patient global impression of improvement questionnaire. Results: 56 women were evaluable. Improvements were found in all micturition symptoms and in particular in voiding symptoms. Feeling of vaginal bulging disappeared in all patients. A slight improvement was found in constipation; 62% of patients had a normal sexual life but 27% refrained from sexual activity. Judgement of patients was between “much improved” and “very much improved”. Conclusions: Disappearance of the feeling of vaginal bulging was by far the best result. Improvements were found in most of the symptoms particularly in voiding symptoms and urodynamic findings.

    Cranial cruciate ligament (CCL) disease is one of the most common causes of lameness in dogs. Surgical treatment is recommended to stabilize the stifle joint, alleviate pain, and delay the progression of osteoarthritis (OA). A variety of surgical techniques has been introduced and can be broken down into the more traditional intracapsular ligament replacement and extracapsular suture techniques and the newer neutralizing dynamic osteotomy techniques. Although an enormous amount of literature ...

    Aneurysms of the splenic artery are the most common splanchnic aneurysms. Aneurysms of a splenic artery with an anomalous origin from the superior mesenteric artery are however rare, with eight previously reported cases. Their indications for treatment are superposable to those of aneurysms affecting an orthotopic artery. Methods of treatment of this condition include endovascular, minimally invasive techniques and surgical resection. We report one more case of aneurysm of an aberrant splenic artery, treated with surgical resection, and preservation of the spleen.

    The effect of hospital specialization on the risk of hernia recurrence after inguinal hernia repair is not well described. We studied Ontario residents who had primary elective inguinal hernia repair at an Ontario hospital between 1993 and 2007 using population-based, administrative health data. We compared patients from a large hernia specialty hospital (Shouldice Hospital) with those from general hospitals to determine the risk of recurrence. We studied 235 192 patients, 27.7% of whom had surgery at Shouldice hospital. The age-standardized proportion of patients who had a recurrence ranged from 5.21% (95% confidence interval [CI] 4.94%-5.49%) among patients who had surgery at the lowest volume general hospitals to 4.79% (95% CI 4.54%-5.04%) who had surgery at the highest volume general hospitals. In contrast, patients who had surgery at the Shouldice Hospital had an age-standardized recurrence risk of 1.15% (95% CI 1.05%-1.25%). Compared with patients who had surgery at the lowest volume hospitals, hernia recurrence among those treated at the Shouldice Hospital was significantly lower after adjustment for the effects of age, sex, comorbidity and income level (adjusted hazard ratio 0.21, 95% CI 0.19-0.23, p hernia repair at Shouldice Hospital was associated with a significantly lower risk of subsequent surgery for recurrence than repair at a general hospital. While specialty hospitals may have better outcomes for treatment of common surgical conditions than general hospitals, these benefits must be weighed against potential negative impacts on clinical care and the financial sustainability of general hospitals.

    2010-03-01

    We determined the relevance of the biomechanical properties of freshly harvested vaginal tissue during large cystocele repair on clinical outcome at a minimum 1-year followup. With institutional review board approval we prospectively studied the biomechanical properties of full thickness vaginal wall tissue from postmenopausal women with symptomatic Baden-Walker prolapse undergoing anterior vaginal wall suspension with cystocele repair from 2002 to 2005. A standardized biomechanical protocol was applied with stress-strain curves for Young's modulus obtained by blinded investigators. Failed repair was defined as recurrence on examination or reoperation for recurrent anterior prolapse. A total of 32 patients (median age 72 years) had a median followup of 34 months (range 12 to 62). Median Young's modulus was statistically different in tissue samples transported in immersed vs moistened media (median 3.8 vs 7.6, p = 0.008). Associations between Young's modulus and clinical variables were described. On followup 7 patients experienced failure of the repair. After controlling for tissue transport protocol no association was seen between Young's modulus and failures (HR 1.1, p = 0.34). This study found no association between Young's modulus and clinical results at long-term followup. This finding suggests that retropubic scarring and pelvic floor muscle properties may be more important for a successful reparative outcome than the intrinsic properties of the vaginal wall. 2010 American Urological Association Education and Research, Inc.

    Routine hernia repair surgery involves the implant of synthetic mesh. However, this type of procedure may give rise to pain and bowel incarceration and strangulation, causing considerable patient disability. The purpose of this study was to compare the long-term behaviour of three commercial meshes used to repair the partially herniated abdomen in New Zealand White rabbits: the heavyweight (HW) mesh, Surgipro(®) and lightweight (LW) mesh, Optilene(®), both made of polypropylene (PP), and a mediumweight (MW) mesh, Infinit(®), made of polytetrafluoroethylene (PTFE). The implanted meshes were mechanical and histological assessed at 14, 90 and 180 days post-implant. This behaviour was compared to the anisotropic mechanical behaviour of the unrepaired abdominal wall in control non-operated rabbits. Both uniaxial mechanical tests conducted in craneo-caudal and perpendicular directions and histological findings revealed substantial collagen growth over the repaired hernial defects causing stiffness in the repair zone, and thus a change in the original properties of the meshes. The mechanical behaviour of the healthy tissue in the craneo-caudal direction was not reproduced by any of the implanted meshes after 14 days or 90 days of implant, whereas in the perpendicular direction, SUR and OPT achieved similar behaviour. From a mechanical standpoint, the anisotropic PP-lightweight meshes may be considered a good choice in the long run, which correlates with the structure of the regenerated tissue.

    Medical records of wild bird admissions to the Australian Wildlife Health Centre at Healesville Sanctuary were analyzed for cases of unilateral coracoid fractures with known final outcomes. Forty-seven birds, comprising 13 species, fit these criteria. Of those birds, 18 were treated conservatively with analgesia and cage rest without coaptation bandaging, and 29 were treated with surgical correction of the fracture. Of the conservatively managed birds, 89% (16 of 18) were released back into the wild. Conversely, 34% (10 of 29) of the surgically managed birds were released. Treatment success for release differed significantly between treatment groups (P birds were not released. Given the high risks associated with surgical treatment and the high success rate of conservative management, cage rest without surgery appears prudent when managing coracoid injuries in birds.

    2016-10-01

    Endovascular aneurysm repair (EVAR) has become the preferred approach for the treatment of infrarenal abdominal aortic aneurysm (IRAAA) in detriment of open surgical repair (OSR). EVAR results in lower mortality rates within 30 days, but rates tend to be the same after longer periods. Moreover, reduced use of hospital resources with EVAR does not necessarily offset the costs of the endoprosthesis. We aimed, in this study, to estimate hospital expenses after OSR or EVAR, including early and late readmissions. Retrospective analysis of hospital expenses (2005-2012) with elective IRAAA surgeries performed in a tertiary hospital, including 127 patients divided into 2 groups, EVAR (n = 102) and OSR (n = 25). One perioperative death occurred in each group. EVAR interventions lasted 145 vs. 210 min of OSR (P hospitalization time differed significantly for EVAR (4 days) and OSR (8 days; P expenses with EVAR were US $53,080.95 and US $56,289.49, respectively. The median and mean expenses with OSR were US $37,116.04 and US $68,788.54, respectively. Early readmissions reached 11.2%. None of the OSR patients required late reinterventions, but 10 (9.9%) EVAR patients did, one of whom died. EVAR resulted in higher expenses with the exclusion of one outlier. Late reinterventions, with elevated costs, were only required by EVAR patients. Thus, when patients are eligible to undergo either intervention, OSR seems to have lower costs and better long-term results. Copyright © 2016 Elsevier Inc. All rights reserved.

No statistically significant correlation was found between percent change in clinical outcome and percent biopsies showing ICRS Excellent scores (R(2)=0.05, p=0.38). Percent change in clinical outcome and percent of biopsies showing only hyaline cartilage were significantly associated (R(2)=0.24, p=0.024). Mean lesion size and histological outcome were not correlated based either on percent ICRS Excellent (R(2)=0.03, p=0.50) or percent hyaline cartilage only (R(2)=0.01, p=0.67). Most common lesion location and histological outcome were not correlated based either on percent ICRS Excellent (R(2)=0.03, p=0.50) or percent hyaline cartilage only (R(2)=0.01, p=0.67). Microfracture has poorer histologic outcomes than other cartilage repair techniques. OATS repairs primarily are comprised of hyaline cartilage, followed closely by cell-based techniques, but no significant difference was found cartilage quality using ICRS grading criteria among OATS, ACI-C, MACI, and ACI-P.

    We report a rare case of severe hemolytic anemia accompanied by moderate renal insufficiency after mitral valve repair. Although the degree of the residual mitral regurgitation was less than 1+ during the first three weeks after the operation, the maximum lactate dehydrogenase (LDH) was up to 7,430 U/l and the minimum hemoglobin was 4.9 g/dl. The mitral valve replacement successfully resolved the hemolysis, but the renal function did not completely recover.

    Full Text Available Background. To analyze the effects of factors other than the ocular trauma score parameters on visual outcomes in open globe injuries. Methods. Open globe injuries primarily repaired in our hospital were reviewed. The number of surgeries, performance of pars plana vitrectomy (PPV, lens status, affected tissues (corneal, scleral, or corneoscleral, intravitreal hemorrhage, intraocular foreign body, glaucoma, anterior segment inflammation, loss of iris tissue, cutting of any prolapsed vitreous in the primary surgery, penetrating injury, and the time interval between the trauma and repair were the thirteen variables evaluated using linear regression analysis. Results. In total, 131 eyes with a mean follow-up of 16.1±4.7 (12–36 months and a mean age of 33.8±22.2 (4–88 years were included. The regression coefficients were 0.502, 0.960, 0.831, −0.385, and −0.506 for the performance of PPV, aphakia after the initial trauma, loss of iris tissue, penetrating injury, and cutting of any prolapsed vitreous in the primary surgery, respectively (P<0.05 for these variables. Conclusions. The performance of PPV, aphakia after the initial trauma, and loss of iris tissue were associated with poor visual outcomes, whereas cutting any prolapsed vitreous in the primary repair and penetrating-type injury were associated with better visual outcomes.

    Full Text Available Significant advances in corneal repair have been made in the past. Tissue graft has been used to repair full-thickness defects of the cornea and sclera. Equine pericardium preserved in glycerol was used to repair full-thickness corneal lesions after limbal melanoma excision and corneal wound with iris prolapse. A six-year old male, German Shepherd, with 1 cm of diameter, dark-pigmented mass at the temporal limbus of the right eye, with two months of evolution, and a four month old female mixed breed dog, with a corneal wound and iris prolapse, in the left eye, secondary to a cat scratch 5 days earlier. In both cases a piece of pericardium was sutured close to the corneal defects. An antibiotic ointment and atropine 1% eye drops were used. The intraocular pressure was low in the following days, but arose to normal values. All other structures were normal. A granulation tissue initially grew near the patch, and the opacity of the pericardium remained. Dexamethasone eye drops and ointment were used, and the granulation tissue disappeared two months after surgery. Eighteen months follow-up showed the eyes in good condition, although opaqueness was still present.

    Full Text Available Cleft lip and palate (CLP is the most common congenital craniofacial anomaly. Rehabilitation of CLP generally requires a team approach. Alveolar and nasal reconstruction for these patients is a challenge for the reconstructive surgeon. Various procedures have been attempted to reduce the cleft gap, so as to obtain esthetic results postsurgically. The presurgical nasoalveolar molding (PNAM technique, developed by Grayson, is a new approach to presurgical infant orthopedics. PNAM reduces the severity of the initial cleft alveolar and nasal deformity. Thus, it enables the surgeon and the patient to enjoy the benefits associated with repair of a cleft deformity that is minimal in severity. This article presents a brief insight into PNAM with a case series of three different cases (one unilateral and two bilateral which underwent PNAM treatment and gave an excellent surgical prognosis.

    Previous work demonstrated that prior MRSA infection [MRSA(+)] is associated with 30-day surgical site infection (SSI) following ventral hernia repair (VHR). We aimed to determine the impact of MRSA(+) on long-term wound outcomes after VHR. A retrospective cohort study was performed at a tertiary center between July 11, 2005, and May 18, 2012, of patients undergoing elective VHR with class I wounds. Patients with documented preoperative MRSA infection at any site (urinary, bloodstream, SSI, etc.) were considered MRSA(+). Primary outcome was 2-year surgical site occurrence (SSO), defined as SSI, cellulitis, necrosis, nonhealing wound, seroma, hematoma, dehiscence, or fistula. SSOs were subdivided into those that required procedural intervention (SSOPI) and those that did not. Among 632 patients, 46 % were female with average age 53 ± 13 years. There were 368 SSOs in 193 patients (31 %); an SSOPI occurred in 9.8 % (n = 62). The most common SSOs were cellulitis (91/632), seroma (91/632), and serous drainage (58/632). The rate of 2-year SSO was higher with MRSA(+) compared to those without (46 vs. 29 %, p = 0.023), attributed to increased soft tissue necrosis, purulent drainage, serous drainage, cellulitis, and fistula. In multivariable analysis, MRSA(+) was not associated with 2-year SSO (HR 1.5, 95 % CI 0.91-2.55, p = 0.113); factors associated with SSO included obesity, immunosuppression, mesh repair, and operative times. This study is the first to evaluate long-term SSOs and SSOPIs after VHR, highlighting the importance of long-term follow-up. Though not independently associated with SSOs, MRSA(+) may be a marker of hernia complexity.

    Abstract To evaluate whether patients aged 80 and older have higher risk of hospital mortality after repair of type A acute aortic dissection (TAAAD). Emergency surgery for TAAAD in patients aged 80 and older remains a controversial issue because of its high surgical risk. Data from patients who underwent surgical repair of TAAAD between April 2011 and March 2013 were retrospectively extracted from the Japanese Diagnosis Procedure Combination database. The effect of age on hospital mortality was evaluated using multivariate logistic regression analysis. A total of 5175 patients were enrolled. The mean age of patients was 67.1 ± 13.0 years, and the male:female ratio was 51:49. Patients aged 80 and older more frequently received tracheostomy than their younger counterparts (9.5% vs 5.4%, P <0.001). Intensive care unit and hospital stays were significantly longer in the elderly cohort versus the younger cohort (7.6 vs 6.7 days, P <0.001, and 42.2 vs 35.8 days, P <0.001, respectively). Logistic regression analysis showed that age ≥80 years was significantly associated with a higher risk of hospital mortality (adjusted odds ratio, 1.62; 95% confidence interval, 1.28–2.06; P <0.001). In linear regression analysis, age ≥80 years was also significantly associated with longer hospital stay (P = 0.007). In a large, nationwide, Japanese database, patients aged 80 and older were at increased risk of hospital mortality and length of hospital stay. PMID:27495057

    PurposeTo investigate the causes and results of late open surgical conversion (LOSC) after failed abdominal aortic aneurysm repair (EVAR) and to summarize our 17 years’ experience with 13 various endografts.MethodsRetrospective data from August 1994 to January 2011 were analyzed at our center. The various devices’ implant time, the types of devices, the rates and causes of LOSC, and the procedures and results of LOSC were analyzed and evaluated.ResultsA total of 1729 endovascular aneurysm repairs were performed in our single center (Nuremberg South Hospital) with 13 various devices within 17 years. The median follow-up period was 51 months (range 9–119 months). Among them, 77 patients with infrarenal abdominal aortic aneurysms received LOSC. The LOSC rate was 4.5 % (77 of 1729). The LOSC rates were significantly different before and after January 2002 (p < 0.001). The reasons of LOSC were mainly large type I endoleaks (n = 51) that were hard to repair by endovascular techniques. For the LOSC procedure, 71 cases were elective and 6 were emergent. The perioperative mortality was 5.2 % (4 of 77): 1 was elective (due to septic shock) and 3 were urgent (due to hemorrhagic shock).ConclusionLarge type I endoleaks were the main reasons for LOSC. The improvement of devices and operators’ experience may decrease the LOSC rate. Urgent LOSC resulted in a high mortality rate, while selective LOSC was relatively safe with significantly lower mortality rate. Early intervention, full preparation, and timely LOSC are important for patients who require LOSC.

    Our hypothesis was that the Achilles tendon healing process after surgical treatment would be promoted by PRP with a faster return to sports activities. Thirty patients with Achilles tendon rupture and surgically treated with a combined mini-open and percutaneous technique were prospectively enroled in the study. Patients were alternately case-by-case assigned to Group A (control group; 15 patients) or Group B (study group; 15 patients). In Group B, PRP was locally infiltrated both during surgery and 14 days after surgery. Patients in both groups were followed up at 1, 3, 6 and 24 months post-operatively via physical examination, VAS, FAOS and VISA-A scales; ultrasonography (US) and MRI were also conducted at one and 6 months; at the 6-month follow-up, isokinetic and jumping capacity tests were also performed. The VAS, FAOS and VISA-A scale showed no difference between the two groups at 1, 3, 6 and 24 months post-operatively. Isokinetic evaluation showed no differences at both angular speeds. Jumping evaluation showed no difference at 6 months. Also US evaluation showed no differences. MRI data analysis before administration of gadolinium did not reveal significant differences between the two groups. Moreover, after intravenous injection of gadolinium, patients in Group B showed signal enhancement in 30 % of patients compared to 80 % in Group A at 6 months, as indirect evidence of better tendon remodelling (P Achilles tendon ruptures surgically treated with and without addition of PRP is shown by present study. Clinical results, morphological features and jumping capability were similar in both groups. The addition of PRP to the surgical treatment of Achilles tendon rupture does not appear to offer superior clinical and functional results. IV.

    Full Text Available Background/Aim. Prolapse of genital organs with or without urinary stress incontinention is the most often health problem in the elderly female population tending to increase with ageing. The aim of this study was to assess the perioperative complications and short-term outcomes of prolaps repair using transvaginal polypropylene mesh (Prolift system, Gynecare, Ethicon, USA. Methods. A retrospective study was conducted evaluating 96 women from September 2006 to January 2010 who undewent vaginal repair with implatation of a soft mesh manufactured by Gynecare, Ethicon, USA. Results. All the patients had a stage 3 or stage 4 prolapse according to the POP-Q system of ICS. Total mesh was used in 12 (13% patients isolated anterior mesh in 52 (54% patients and isolated posterior mesh in 32 (33% patients. We reported one intra-operative bladder injury and no other serious complications. At 3 months, all 96 patients were available for follow-up. Vaginal erosion occured in 9 (9.3% patients, shrinkage of mesh in 6 (6.2% patients and de novo urinary incontinence in 5 (5.2% patients. Failure rate was 6.25% (recurrent prolapse stage 3 or 4 even asymptomatic. Conclusion. Our study suggests that transvaginal polypropylene mesh applied with a tensionfree technique is a safe and effective method with low intraoperative complications and low morbidity rates. However, some complications are serious and require highly specialised management.

    Five New World camelids were admitted to the Western College of Veterinary Medicine between 1996 and 2003 for evaluation of femoral fractures. There were three alpacas and two llamas. Four of the animals were female and three were less than 3 months of age. Fracture configurations consisted of distal physeal fractures (three), a comminuted diaphyseal/metaphyseal fracture, and a transverse diaphyseal fracture. Fractures were diagnosed with a combination of physical examination and radiographs in all cases. All five fractures were repaired with internal fixation and three animals were discharged from the hospital with fractures that healed. One cria underwent successful internal fixation but died from pulmonary oedema during recovery from anaesthesia. Postoperative complications were rare and limited to inadequate fracture stability in one alpaca and prolonged recovery to weight bearing in another. One llama with a comminuted metaphyseal fracture, repaired with a 4.5 mm dynamic compression plate, subsequently had catastrophic failure of the bone 17 days after surgery. Overall the clients were pleased with the outcome of discharged animals. Although femoral fractures are considered rare, they pose a unique opportunity for the large animal veterinarian to successfully achieve fracture union with the aid of internal fixation.

    Full Text Available Background: There are few predictors of difficult mask ventilation and a simple, objective, predictive system to identify patients at risk of difficult mask ventilation does not currently exist. We present a retrospective - subgroup analysis aimed at identifying predictive factors for difficult mask ventilation (DMV in patients undergoing pre-operative airway assessment before elective surgery at a major teaching hospital. Methods: Data for this retrospective analysis were derived from a database of airway assessments, management plans, and outcomes that were collected prospectively from August 2008 to May 2010 at a Level 1 academic trauma center. Patients were stratified into two groups based on the difficulty of mask ventilation and the cohorts were analyzed using univariate analysis and stepwise selection method. Results: A total of 1399 pre-operative assessments were completed with documentation stating that mask ventilation was attempted. Of those 1399, 124 (8.9% patients were found to be difficult to mask ventilate. A comparison of patients with and without difficult mask ventilation identified seven risk factors for DMV: age, body mass index (BMI, neck circumference, history of difficult intubation, presence of facial hair, perceived short neck and obstructive sleep apnea. Although seven risk factors were identified, no individual subject had more than four risk factors. Conclusion: The results of this study confirm that in a real world clinical setting, the incidence of DMV is not negligible and suggest the use of a simple bedside predictive score to improve the accuracy of DMV prediction, thereby improving patient safety. Further prospective studies to validate this score would be useful.

    BACKGROUND There has been no published report assessing the mechanical properties of a repaired Achilles tendon after surgery using shear wave elastography (SWE). The aim of this study was to investigate the changes in mechanical properties of the healing Achilles tendon after surgical repair of a tendon rupture using ultrasound SWE and how these changes correlate with tendon function. MATERIAL AND METHODS Twenty-six patients who underwent surgical repair for Achilles tendon rupture were examined with ultrasound SWE coupled with a linear array transducer (4-15 MHz). The elasticity values of the repaired Achilles tendon in a longitudinal view were measured at 12, 24, and 48 weeks postoperatively. Functional outcomes were assessed with the American Orthopedic Foot and Ankle Society (AOFAS) rating system at 12, 24, and 48 weeks postoperatively. General linear regression analysis and correlation coefficients were used to analyze the relationship between elasticity and the AOFAS score. RESULTS There were significant differences with respect to the mean elasticity values and functional scores of the repaired Achilles tendon at 12, 24, and 48 weeks postoperatively (all PTendon function was positively correlated with the elasticity of the repaired Achilles tendon (P=0.0003). CONCLUSIONS Our findings suggest that SWE can provide biomechanical information for evaluating the mechanical properties of healing Achilles tendon and predict Achilles tendon function.

    A 55-year-old woman with a background of vascular disease presented with signs of bilateral limb ischaemia. Following elective axillobifemoral bypass and hospital discharge, accidental axillary trauma causing a chest wall haematoma, the patient underwent an emergency graft repair. Postextubation, she reported with absent sensation in her legs. Spinal cord infarction was diagnosed through clinical assessment and exclusion of other causes. The aetiology of compromise to the spinal cord blood supply is unclear. Possibilities include intraoperative hypotension, inadvertent compromise to blood supply of thoracic radicular arteries, dislodged atherosclerotic emboli or a combination of these factors. Spinal cord infarction recognised early can be treated. Sedation to assist ventilation had obscured the problem early enough to consider treatment. Patients with vascular risk factors should be carefully managed intraoperatively to minimise hypotensive episodes and care should also be taken not to compromise blood flow of radicular arteries.

    Paintings and drawings by Lucas Moser, Leonardo da Vinci, Albrecht Dürer, and Jacob Cornelisz van Oostsanen suggest that they employed people who had had cleft lips operated on as models for their works of art. Created between 1431 and 1520, the portraits show diagnostic facial profiles with a curved nasal dorsum, short columella, maxillary retrusion, and pseudoprogenia. The first medical illustration of cleft lip surgery was published in 1564 by Ambroise Paré. It was therefore late Gothic and Renaissance artists who depicted the conspicuous signs of surgically treated patients with cleft lip more than 130 years before the surgeons.

    Full Text Available We report the case of a patient with a pseudoaneurysm of the ascending aortic clinically diagnosed 5 months after surgical replacement of the aortic valve. Diagnosis was confirmed with the aid of two-dimensional echocardiography and helicoidal angiotomography. The corrective surgery, which consisted of a reinforced suture of the communication with the ascending aorta after opening and aspiration of the cavity of the pseudoaneurysm, was successfully performed through a complete sternotomy using extracorporeal circulation, femorofemoral cannulation, and moderate hypothermia, with no aortic clamping.

    Full Text Available In the last thirty years, steady progress in the diagnostic tools and care of subjects affected by congenital heart diseases (CHD has resulted in a significant increase in their survival to adulthood, even for those affected by complex CHD. Based on these premises, a number of teenagers and adults affected by corrected (surgically or through interventional techniques CHD ask to be allowed to undertake sporting activities, both at a recreational and competitive level. The purpose of this review is to examine the mechanisms influencing the adaption at physical exercise of patients suffering from complex CHD. The conclusion is that even if there are some modest risks with exercise, they should be seen in perspective, and the life-long benefits of regular exercise on general health, mood, and well-being should be emphasized.

    Tissue reactions to titanium-nickelide and polypropylen and caprone implants used in surgical treatment of anterior aldomen wall hernias were studied in experiment. Digital density of leukocytes, fibroblasts, vessels, thickness of the capsule were studied. Pronounced inflammatory reaction was observed on day 3 which attenuated on day 14 in case of titanium nickelide and on day 30-60 in case of polypropylene and caprone. Fibroplastic processes start in the first group after 7 days while in the second group only after 30 days of the experiment. Thickness of the capsule around titanium-nickelide was 2-3 times less than around polypropylene and caprone. Thus, titanium-nickelide material is biologically more inert than caprone and polypropylen which are widely used in surgery of hernias.

    Full Text Available From a biological standpoint, the best material for reconstruction of bone defects is the autogenous bone graft. However, as tissue healing is affected under diabetic conditions, major changes might take place in the revascularization, incorporation, replacement and remodeling phases of the grafted area. The purpose of this study was to assess the bone healing process in surgical wounds prepared in tibiae of diabetic rats and filled with autogenous bone. Forty male rats (Rattus norvegicus albinus, Wistar were randomly assigned to receive an endovenous injection (penile vein of either citrate buffer solution (Group 1 - control; n=20 or streptozotocin dissolved in citrate buffer solution (35 mg/kg to induce diabetes (Group 2 - diabetic; n=20. After determination of glycemia, the animals were anesthetized and the anterolateral regions of the tibiae of both limbs were shaved, antisepsis was performed and longitudinal incisions were made in each limb. The tibiae were exposed and two 2mm-diameter surgical cavities were prepared: one in the right limb, filled with particulate autogenous bone and the other in the left limb, filled with blood clot. The animals were euthanized at 10 and 30 postoperative days. The anatomic pieces were obtained, submitted to laboratory processing and sections were stained by hematoxylin and eosin and Masson's Trichrome for histomorphologic and histometric analyses. In both groups, the wounds filled with autogenous bone graft showed better results than those filled with blood clot. The control group showed higher new bone formation in wounds filled with autogenous bone graft at 30 days than the diabetic group, but without statistical significance. It may be concluded that, in general, the new bone formation occurred with autogenous graft was quantitatively similar between control and diabetic groups and qualitatively better in the control group.

    Full Text Available The cytotoxicity and biosafety of poly-(3-hydroxybutyrate (P3HB and poly-(3-hydroxybutyrate-co-3-hydroxyvalerate (P3HBV films were investigated in vitro using 3T3 fibroblast cells and in vivo through subcutaneous implantation of the film in mice. The in vitro test revealed that endotoxin-free P3HB and P3HBV films allowed cell attachment and growth. Film-soaked conditional media showed no significant inhibitory or cytotoxic effects on cell proliferation. The in vivo absorption test showed that both the P3HB and P3HBV films slowly degraded and that P3HB had a slower degradation rate than that of P3HBV. Applying a P3HB film in hernia repair demonstrated a favorable outcome: the film was able to correct the abdominal ventral hernia by inducing connective tissue and fat ingrowth and exhibited an extremely slow rate of degradation. Furthermore, the P3HB film demonstrated the advantage of lower intestinal adhesion to the ventral hernia site compared with the P3HBV and PP commercial films.

    Lesions of articular cartilage have a large variety of causes among which traumatic damage, osteoarthritis and osteochondritis dissecans are the most frequent. Replacement of articular defects in joints has assumed greater importance in recent years. This interest results in large part because cartilage defects cannot adequately heal themselves. Many techniques have been suggested over the last 30 years, but none allows the regeneration of the damaged cartilage, i.e. its replacement by a strictly identical tissue. In the first generation of techniques, relief of pain was the main concern, which could be provided by techniques in which cartilage was replaced by fibrocartilage. Disappointing results led investigators to focus on more appropriate bioregenerative approaches using transplantation of autologous cells into the lesion. Unfortunately, none of these approaches has provided a perfect final solution to the problem. The latest generation of techniques, currently in the developmental or preclinical stages, involve biomaterials for the repair of chondral or osteochondral lesions. Many of these scaffolds are designed to be seeded with chondrocytes or progenitor cells. Among natural and synthetic polymers, collagen- and polysaccharide-based biomaterials have been extensively used. For both these supports, studies have shown that chondrocytes maintain their phenotype when cultured in three dimensions. In both types of culture, a glycosaminoglycan-rich deposit is formed on the surface and in the inner region of the cultured cartilage, and type II collagen synthesis is also observed. Dynamic conditions can also improve the composition of such three-dimensional constructs. Many improvements are still required, however, in a number of key aspects that so far have received only scant attention. These aspects include: adhesion/integration of the graft with the adjacent native cartilage, cell-seeding with genetically-modified cell populations, biomaterials that can be

    The objective of this study was to describe a comprehensive five-step surgical management approach for patients with penetrating liver trauma based on our collective institutional experience. A prospective consecutive study of all penetrating liver traumas from January 2003 to December 2011 at a regional Level I trauma center in Cali, Colombia, was conducted. A total of 538 patients with penetrating thoracoabdominal trauma were operated on at our institution. Of these, 146 had penetrating liver injuries that satisfied the inclusion criteria for surgical intervention to manage their hepatic and/or associated injuries. Eighty-eight patients (60%) had an American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS) of Grade III (54 patients, 37%), Grade IV (24 patients, 16%), and Grade V (10 patients, 7%). This group of patients required advanced "complex" techniques of hemostasis such as the Pringle maneuver (PM), perihepatic liver packing (PHLP), and/or hepatotomy with selective vessel ligation (SVL). The focus of our study was this subgroup of patients, which we further divided into two as follows: those who required only PM + PHLP (55 patients, 63%) to obtain control of their liver hemorrhage and those who required PM + PHLP + SVL (33 patients, 37%). Of the patients who required PM + PHLP + SVL, 10 (27%) required ligation of major intrahepatic branches, which included suprahepatic veins (n = 4), portal vein (n = 4), retrohepatic vena cava (n = 1), and hepatic artery (n = 1). The remaining 23 patients (73%) required direct vessel ligation of smaller intraparenchymal vessels. The overall mortality was 15.9% (14 of 88), with 71.4% (10 of 14) related to coagulopathy. Mortality rates for Grade III was 3.7% (2 of 54), for Grade IV was 20.8% (5 of 24), and for Grade V was 70% (7 of 10). The mortality in the PM + PHLP + SVL group was higher compared with the PM + PHLP group (12 [36.4%] vs. 2 [3.6%], p = 0.001]. For those patients who fail to respond to PM

    Odontogenic sinusitis accounts for 10-12% of maxillary sinusitis. It occurs due to an interruption of the mucoperiosteum in response to a series of conditions, most frequently the extraction of a superior tooth. Its treatment has two bases: treating the infection and managing the oroantral fistula that perpetuates the infection. Communications smaller than 5mm can resolve spontaneously; bigger ones must be closed by a flap. Bichat's fat pad flap was first used in 1977 to close an oroantral fistula. It is a pedicled flap that has been shown to be successful, with advantages that make it the best option in oroantral fistula treatment. Its location allows easy access, minimum dissection, great versatility, good mobility, good blood supply, low rate of complications, no morbidity in the donor site, low risk of infection, shortened surgical time and fast cover by epithelium, and it leaves no visible scar, amongst other benefits. That is why we encourage the use of this technique and choose it as the best option for management of our patients.

    Obturator hernia is the protrusion of intraperitoneal or extraperitoneal organs or tissues through the obturator canal. The first case was published by de Ronsil in 1724. Obturator hernia is more common in older malnourished women due to loss of supporting connective tissue and the wider female pelvis. The hernia sac usually contains small bowel, especially ileum. It may follow the anterior or posterior division of the obturator nerve. In most cases, obturator hernia presents with intestinal obstruction of unknown cause. It may present with obturator neuralgia, as a palpable mass or, in cases of bowel necrosis, as ecchymosis of the thigh. A correct diagnosis is made in 20 to 30 per cent of cases. CT scan is considered the gold standard for diagnosis, whereas ultrasonography, contrast studies, herniography and plain films are less specific. Surgery is the only treatment option for obturator hernia. Hesitancy to intervene surgically for chronically ill patients results in high mortality. Transabdominal approach is indicated in cases of complete bowel obstruction or suspected peritonitis. The extra-abdominal approach is used in preoperatively diagnosed cases and in absence of bowel strangulation. The laparoscopic approach is minimally invasive and effectively reduces morbidity. The defect is closed using sutures, tissue flaps, or prosthetic mesh.

    Trocar-site hernias are rare complications of laparoscopic surgery. Although trocar-site hernias occur more often at >10-mm sites, hernias can still develop at 5-mm sites after laparoscopy and can lead to serious complications. The primary objective of this review is to summarize the current medical literature pertaining to the clinical presentation and predisposing risk factors of trocar-site hernias at 5-mm sites after laparoscopy. A total of 295 publications were identified, 17 (5.76%) of which met the inclusion criteria. Twenty-seven patients with trocar-site hernias were identified after laparoscopic cases. The median age (interquartile range) for all adult patients with trocar-site hernias was 63 years (interquartile range, 39.5-66.5 years). Eight of the 18 patients (44.4%) undergoing gynecologic laparoscopy were parous although details of parity were not reported in most publications. Simple manual reduction or laparoscopic reduction with fascial closure (21 patients [84%]) was used more often compared with exploratory laparotomy (4 patients [16%], p manipulation can extend 5-mm fascial incisions, thereby increasing the risk of trocar-site hernias. Parous women older than 60 years may have unrecognized fascial defects, which confer a higher risk of trocar-site hernias after laparoscopic surgery, even in the absence of incision manipulation or prolonged surgical duration. Such patients may benefit from closure of 5-mm fascial incisions although prospective data are required to validate the overall generalizability of this management strategy.

    Abstract Objective: To evaluate 3D nasal morphology following primary reconstruction in children with unilateral cleft lip and palate relative to contemporaneous non-cleft data Design: Prospective, cross-sectional, controlled study. Setting: Glasgow Dental Hospital & School, Faculty of Medicine, Glasgow University Patients and Participants: Two groups of 3-year old children (21 with unilateral cleft lip and palate and 96 controls) with facial images taken using a 3D vision based capture technique. Methods: 3D images of the face were reflected so the cleft was on the left side to create a homogenous group for statistical analysis. Three-dimensional co-ordinates of anthropometric landmarks were extracted from facial images by a single operator. A set of linear measurements was utilised to compare cleft and control subjects on right and left sides, adjusting for sex differences Results: the mean nasal base width and the width of the nostril floor on right and left sides differed significantly between control and Unilateral Cleft Lip and Palate (UCLP) groups. The measurements were greater in UCLP children. The difference in the mean nasal height and mean nasal projection between the groups were not statistically significant. Mean columellar lengths were different between the left and right sides in UCLP cases. Conclusions: There were significant nasal deformities following the surgical repair of UCLP. Keywords: child, cleft lip and palate, three-dimensional imaging.

    Full Text Available Fast-track extubation is an established safe practice in pediatric congenital heart disease (CHD surgical patients. On table extubation (OTE in acyanotic CHD surgical patients is well established with validated safety profile. This practice is not yet reported in tetralogy of Fallot (TOF cardiac surgical repair patients in developing countries. Evidence suggests that TOF total correction patients should be extubated early, as positive pressure ventilation has a negative impact on right ventricular function and the overall increase in post-TOF repair complications such as low cardiac output state and arrhythmias. The objective of the case series was to determine the safety and feasibility of OTE in elective TOF total correction cardiac surgical patients with an integrated team approach. To the best of our knowledge, this is the first reported case series. A total of 8 elective male and female TOF patients were included. Standard anesthetic, surgical and perfusion techniques were used in these procedures. All patients were extubated in the operating room safely without any complications with the exception of one patient who continued to bleed for 3 h of postextubation at 2-3 ml/kg/h which was managed with transfusion of fresh frozen plasma at 15 mL/kg, packed red blood cells 10 mL/kg and bolus of transamine at 20 mg/kg. Apart from better surgical and bypass techniques, the most important factor leading to successful OTE was an excellent analgesia. On the basis of the case series, it is suggested to extubate selected TOF cardiac surgery repair patients on table safely with integrated multidisciplinary approach.

    Sudden death is a possible occurrence for newborns younger than 1 year with severe aortic coarctation (CoA) before surgical correction. In our previous study, we showed a significant increase of QTc-D and JTc-D in newborns with isolated severe aortic coarctation, electrocardiographic parameters that clinical and experimental studies have suggested could reflect the physiological variability of regional and ventricular repolarization and could provide a substrate for life-threatening ventricular arrhythmias. The aim of the current study was to evaluate the effect of surgical repair of CoA on QTc-d, JTc-d in severe aortic coarctation newborns with no associated congenital cardiac malformations. The study included 30 newborns (18M; 70+/-12 h old) affected by severe congenital aortic coarctation, without associated cardiac malformations. All newborns underwent to classic extended end-to-end repair. Echocardiographic and electrocardiographic measurements were performed in each patient 24 h before and 24 h after the interventional procedure and at the end of the follow-up period, 1 month after the surgical correction. All patients at baseline, 24 h and one month after CoA surgical repair did not significantly differ in terms of heart rate, weight, height, and echocardiographic parameters. There were no statistically significant differences in QTc-D (111.7+/-47.4 vs 111.9+/-63.8 ms vs 108.5+/-55.4 ms; P=0.4) and JTc-D (98.1+/-41.3 vs 111.4+/-47.5 vs 105.1+/-33.4 ms; P=0.3) before, 24 h and 1 month after CoA surgical correction. In conclusions, our study did not show a statistically significant decrease in QTc-D and JTc-D, suggesting the hypothesis that the acute left ventricular afterload reduction, related to successful CoA surgical correction, may not reduce the ventricular electrical instability in the short-term follow-up.

    Background Although it is generally acknowledged that patients with ruptured abdominal aortic aneurysm (rAAA)obtain the greatest benefit from endovascular repair (EVAR),convincing evidence on the medium-long term effect is lacking.The aim of this study was to compare and summarize published results of rAAA that underwent EVAR with open surgical repair (OSR).Methods A search of publicly published literature was performed.Based on an inclusion and exclusion criteria,a systematic meta-analysis was undertaken to compare patient characteristics,complications,short term mortality and medium-long term outcomes.A random-effects model was used to pool the data and calculate pooled odds ratios and weighted mean differences.A quantitative method was used to analyze the differences between these two methods.Results A search of the published literature showed that fourteen English language papers comprising totally 1213 patients with rAAA (435 EVAR and 778 OSR) would be suitable for this study.Furthermore,13 Chinese studies were included,including 267 patients with rAAA totally,among which 238 patients received operation.The endovascular method was associated with more respiratory diseases before treatment (OR=1.81,P=0.01),while there are more patients with hemodynamic instability before treatment in OSR group (OR=1.53,P=0.031).Mean blood transfusion was 1328 ml for EVAR and 2809 ml for OSR (weighted mean difference (WMD) 1500 ml,P=0.014).The endovascular method was associated with a shorter stay in intensive care (WMD 2.34 days,P <0.001) and a shorter total postoperative stay (WMD 6.27 days,P <0.001).The pooled post-operative complication rate of respiratory system and visceral ischemia seldom occurred in the EVAR group (OR=0.48,P <0.001 and OR=0.28,P=0.043,respectively).The pooled 30-day mortality was 25.7% for EVAR and 39.6% for OSR,and the odds ratio was 0.53 (95% confidence interval (CI) 0.41-0.70,P <0.001).There was not,however,any significant reduction in

    Full Text Available BACKGROUND: Chronic hydrocele is the most common manifestation of bancroftian filariasis, an endemic disease in 80 countries. In a prospective study, we evaluated the occurrence of intrascrotal lymphangiectasia, gross appearance/consistency of the testis, and the efficacy of complete excision of hydrocele sac in patients living in a bancroftian filariasis endemic area who underwent hydrocelectomy at the Center for Teaching, Research and Tertiary Referral for Bancroftian Filariasis (NEPAF. METHODOLOGY/PRINCIPAL FINDINGS: A total of 968 patients with uni- or bilateral filarial hydrocele (Group-1 and a Comparison Group (CG of 218 patients from the same area who already had undergone hydrocele-sac-sparing hydrocelectomy elsewhere were enrolled at NEPAF. Twenty-eight patients from the Comparison Group with hydrocele recurrence were re-operated on at NEPAF and constitute Group-2. In Group-1 a total of 1,128 hydrocelectomies were performed (mean patient age of 30.3 yr and mean follow-up of 8.6 yr [range 5.3-12]. The hydrocele recurrence rates in Group-1 and in the Comparison Group (mean age of 31.5 yr were 0.3%, and 19.3%, respectively (p<0,001. There was no hydrocele recurrence in Group-2 (mean patient age of 25.1 yr and mean follow-up of 6 yr [range 5-6.9]. Per surgically leaking or leak-prone dilated lymphatic vessels were seen in the inner or outer surface of the hydrocele sac wall or in surrounding tissue, particularly in the retrotesticular area, in 30.9% and in 46.3% of patients in Group-1 and Group-2, respectively (p = 0.081. The testicles were abnormal in shape, volume, and consistency in 203/1,128 (18% and 10/28 (35.7% of patients from Group-1 and Group-2, respectively (p = 0,025. CONCLUSIONS/SIGNIFICANCE: Lymph fluid from ruptured dilated lymphatic vessels is an important component of chronic filarial hydrocele fluid that threatens the integrity of the testis in an adult population living in bancroftian filariasis endemic areas.

    Conclusion: The outcome of rapid two-stage repair is comparable to that of one-stage repair. Rapid two-stage repair has the advantages of significantly shorter cardiopulmonary bypass duration and AXC time, and avoids deep hypothermic circulatory arrest. LVOTO remains an unresolved issue, and postoperative aortic arch restenosis can be dilated effectively by percutaneous balloon angioplasty.

    Goal. To demonstrate the Heidelberg results of the previous 2 years in patients referred for acute aortic dissection. Material and Methods. 93 patients referred for acute aortic dissection were treated by cardiac surgery, vascular surgery and interventional radiology according to a novel therapeutic algorithm including stent-grafts and combined open and interventional procedures and conservative medical therapy when no malperfusion syndrome was present or patients were considered prohibitive for even minor surgical procedures. Stent-graft placements were done assisted by short term cardiac arrest to facilitate correct device deployment. Results. 36 patients presented with type A and the other 57 with type B dissection. 32 of the A patients were operated and 20 of the B patients, respectively. 12 patients with B dissection were treated with stent-grafts. 3 required additional interventional therapy for organ malperfusion. The mortality was 0% in these 12 patients. The overall mortality rate in the A group was close to 40% mainly as a result of postoperative organ malperfusion while it was 15% in the B group. In both groups mortality was highest in the respective untreated patient subgroup (3/4 and 8/37, respectively). The main mortality factor was visceral (mesenteric or liver) ischemia. Paraplegic complications occured in neither group. In 4 patients a combined approach applying cardiac surgery of the ascending aorta and endluminal stent-graft placement for the residual B dissection was successfully performed. In one patient this was done simultaneously. Discussion. Acute aortic dissection of type A with or without valve involvement, coronary artery ischemia can be treated with high technical success rates. However, remaining distal aortic dissection associated with true lumen collapse and organ malperfusion is the main causative factor for clinical failures. Successful combination of open proximal aortic surgery with endoluminal treatment of residual B dissection

    The complementary role of mitral valve repair versus replacement is based on evidence of long-term results in open surgery. Transcatheter mitral valve repair and replacement are both under rapid development but subject to clinical feasibility and first in-human short- and midterm outcome studies. The present article aims to review mitral valve repair and replacement by both techniques and to elucidate similar and potentially different aspects among the open and interventional approach.

    We evaluated regional right ventricular wall motion during systole in patients with surgically repaired tetralogy of Fallot (TOF) using color kinesis imaging. Color kinesis images were obtained in a subcostal sagittal view from 19 patients with repaired TOF (TOF group), aged 3 to 5 years, and 20 age-matched normal subjects (control group). For regional wall motion analysis, the endocardial motion distance and the fractional area change (FAC) were calculated for 6 segments obtained from color kinesis images. The endocardial inward excursion distances and the FACs in the upper, middle, and lower posterior segments of the TOF group were significantly greater than those of the control group (p kinesis measurements was excellent (y = 1.14x - 1.30, r = 0.87 for the endocardial inward excursion, and y = 1.03x +/- 0.56, r = 0.91 for the FAC). In conclusion, color kinesis is a useful method for assessing regional right ventricular wall motion. Segmental analysis of color kinesis images provides accurate, automated, and quantitative diagnosis of regional right ventricular wall motion abnormalities in patients with surgically repaired TOF.

    Surgical mitral valve repair is the procedure of choice to treat mitral regurgitation of all etiologies. Whereas annuloplasty is the cornerstone of mitral valve repair, a variety of other surgical techniques are utilized to correct dysfunction of the leaflets and subvalvular apparatus; in most cases, surgical repair entails application of multiple repair techniques in each patient. Preclinical studies and early human experience have demonstrated that some of these surgical repair techniques can be performed using percutaneous approaches. Specifically, there has been great progress in the development of novel technology to facilitate percutaneous annuloplasty and percutaneous edge-to-edge repair. The objectives of this report were to (1) discuss the surgical foundations for these percutaneous approaches; (2) review device design and experimental and clinical results of percutaneous valve repair; and (3) address future directions, including the key challenges of patient selection and clinical trial design.

    An ex vivo study was conducted to determine the effect of the irregularity of the scaffold surface on the tensile strength of repairs formed using our Scaffold-Enhanced Biological Adhesive (SEBA). Two different scaffold materials were investigated: (i) a synthetic biodegradable material fabricated from poly(L-lactic-co-glycolic acid); and (ii) a biological material, small intestinal submucosa, manufactured by Cook BioTech. The scaffolds were doped with protein solder composed of 50%(w/v) bovine serum albumin solder and 0.5mg/ml indocyanine green dye mixed in deionized water, and activated with an 808-nm diode laser. The tensile strength of repairs performed on bovine thoracic aorta, liver, spleen, small intestine and lung, using the smooth and irregular surfaces of the above scaffold-enhanced materials were measured and the time-to-failure was recorded. The tensile strength of repairs formed using the irregular surfaces of the scaffolds were consistently higher than those formed using the smooth surfaces of the scaffolds. The largest difference was observed on repairs formed on the aorta and small intestine, where the repairs were, on average, 50% stronger using the irregular versus the smooth scaffold surfaces. In addition, the time-to-failure of repairs formed using the irregular surfaces of the scaffolds were between 50% and 100% longer than that achieved using the smooth surfaces of the scaffolds. It has previously been shown that distributing or dispersing the adhesive forces over the increased surface area of the scaffold, either smooth or irregular, produces stronger repairs than albumin solder alone. The increase in the absolute strength and longevity of repairs seen in this new study when the irregular surfaces of the scaffolds are used is thought to be due to the distribution of forces between the many independent micro-adhesions provided by the irregular surfaces.

    Objective: The aim of the study was to evaluate biosynthetic absorbable mesh in single-staged contaminated (Centers for Disease Control class II and III) ventral hernia (CVH) repair over 24 months. Background: CVH has an increased risk of postoperative infection. CVH repair with synthetic or biologic meshes has reported chronic biomaterial infections and high hernia recurrence rates. Methods: Patients with a contaminated or clean-contaminated operative field and a hernia defect at least 9 cm2 had a biosynthetic mesh (open, sublay, retrorectus, or intraperitoneal) repair with fascial closure (n = 104). Endpoints included overall Kaplan-Meier estimates for hernia recurrence and postoperative wound infection rates at 24 months, and the EQ-5D and Short Form 12 Health Survey (SF-12). Analyses were conducted on the intent-to-treat population, and health outcome measures evaluated using paired t tests. Results: Patients had a mean age of 58 years, body mass index of 28 kg/m2, 77% had contaminated wounds, and 84% completed 24-months follow-up. Concomitant procedures included fistula takedown (n = 24) or removal of infected previously placed mesh (n = 29). Hernia recurrence rate was 17% (n = 16). At the time of CVH repair, intraperitoneal placement of the biosynthetic mesh significantly increased the risk of recurrences (P ≤ 0.04). Surgical site infections (19/104) led to higher risk of recurrence (P < 0.01). Mean 24-month EQ-5D (index and visual analogue) and SF-12 physical component and mental scores improved from baseline (P < 0.05). Conclusions: In this prospective longitudinal study, biosynthetic absorbable mesh showed efficacy in terms of long-term recurrence and quality of life for CVH repair patients and offers an alternative to biologic and permanent synthetic meshes in these complex situations.

    This article summarizes the detailed cost-effectiveness analysis of delirium prevention interventions in people undergoing surgical repair of hip fracture. We compared a multi-component delirium prevention intervention with usual care using a model based on a decision tree analysis. The model was used to estimate the incremental net monetary benefit (INMB). The robustness of the cost-effectiveness result was explored using deterministic and probabilistic sensitivity analyses. The multi-component prevention intervention was cost-effective when compared to usual care. It was associated with an INMB of £8,180 using a cost-effectiveness threshold of £20,000 per QALY. It remained cost-effective in the majority of the deterministic sensitivity analyses and was cost-effective in 96.4 % of the simulations carried out in the probabilistic sensitivity analysis. We have demonstrated the cost-effectiveness of a multi-component delirium prevention intervention that targets modifiable risk factors for delirium in older people undergoing surgical repair of hip fracture. It is an attractive intervention for practitioners and health care policy makers as they address the double burden of hip fracture and delirium.

  11. A non-invasive technique for standing surgical repair of urinary bladder rupture in a post-partum mare: a case report

    2009-11-01

    Full Text Available Abstract An 11-year-old mare presented 36 hours after foaling with a ruptured bladder. Uroperitoneum was diagnosed on ultrasound and from the creatinine concentration of the peritoneal fluid. Bladder endoscopy demonstrated tissue necrosis and a rent in the dorsocranial aspect of the bladder. Following stabilisation, including abdominal drainage and lavage, the mare was taken to standing surgery. Under continuous sedation and epidural anaesthesia, and after surgical preparation, a Balfour retractor was placed in the vagina. Using sterile lubricant and moderate force, it was possible to insert a hand into the bladder. The tear was easily palpable on the dorsal portion of the bladder. Two fingers were inserted through the tear and used to provide traction to evert the bladder completely into the vagina where it could grasped with the surgeons other hand to prevent further trauma. A second surgeon could then visualise the entire tear and repaired this using a single layer of size zero PDS suture in a single continuous pattern. As soon as the bladder was repaired, it was replaced via the urethra. The mare did well after surgery and was discharged after 48 hours, apparently normal. This report is the first describing repair of the bladder without an abdominal incision or incision into the urethral sphincter. This greatly reduces the chance of possible complications such as urine pooling after surgery with the previously described standing technique or bladder trauma due to traction with abdominal surgery.

    we sought to determine whether patients with functional mitral regurgitation (FMR) would benefit from ventricular reshaping by the Coapsys device (Myocor, Inc., Maple Grove, Minnesota). FMR occurs when ventricular remodeling impairs valve function. Coapsys is a ventricular shape change device placed without cardiopulmonary bypass to reduce FMR. It compresses the mitral annulus and reshapes the ventricle. We hypothesized that Coapsys for FMR would improve clinical outcomes compared with standard therapies. RESTOR-MV (Randomized Evaluation of a Surgical Treatment for Off-Pump Repair of the Mitral Valve) was a randomized, prospective, multicenter study of patients with FMR and coronary disease with core laboratory analysis. After enrollment, patients were stratified to the standard indicated surgery: either coronary artery bypass graft alone or coronary artery bypass graft with mitral valve repair. In each stratum, randomization was to either control (indicated surgery) or treatment (coronary artery bypass graft with Coapsys ventricular reshaping). the study was terminated when the sponsor failed to secure ongoing funding; 165 patients were randomized. Control and Coapsys both produced decreases in left ventricular (LV) end-diastolic dimension and MR at 2 years (p stroke, myocardial infarction, and valve reoperation) was significantly greater with Coapsys at 2 years (85% vs. 71%) (hazard ratio: 0.372; 95% confidence interval: 0.185 to 0.749; adjusted log-rank test; p = 0.019). analysis of RESTOR-MV indicates that patients with FMR requiring revascularization treated with ventricular reshaping rather than standard surgery had improved survival and a significant decrease in major adverse outcomes. This trial validates the concept of the ventricular reshaping strategy in this subset of patients with heart failure.

    Transversus abdominis plane (TAP) and ilioinguinal/iliohypogastric (II/IH) nerve blocks have been described as analgesic adjuncts for inguinal hernia repair, but the efficacy of these techniques in providing intraoperative anesthesia, either individually or together, is not known. We designed this retrospective cohort study to test the hypothesis that combining TAP and II/IH nerve blocks ("double TAP" technique) results in greater accordance between the preoperative anesthetic plan and actual anesthetic technique provided when compared to TAP alone. Based on this study, double TAP may be preferred for patients undergoing open inguinal hernia repair who wish to avoid general anesthesia.

    This is a case report of an adolescent male who underwent surgical ligation for a left-sided varicocele that recurred 2 years later. Standard retrograde embolization via the left renal vein was not possible, because there was no connection from the renal vein to the gonadal vein following surgical ligation. The patient was treated via antegrade access of the spermatic vein at the inguinal level with subsequent coil embolization.

    Patients who have had an Achilles tendon (AT) rupture repaired are potentially at higher risk for re-rupture than those without previous rupture. Little attention has been given to the neuromechanical modulation of muscle-tendon interaction and muscle activation profiles during human dynamic movements after AT rupture repair. The purpose of this study was to examine muscle-tendon behavior and muscle activation during bilateral hopping. We enrolled nine subjects who had undergone surgical repair of unilateral AT rupture within the past 1-2 years. Subjects performed bilateral hopping while we took ultrasound, kinematic, and electromyogram recordings and measurements. AT behaviors were also recorded. We then compared responses between values obtained from the ruptured AT leg (LEGATR) and non-ruptured AT leg (LEGNOR). During hopping, the AT stretching amplitudes were greater in the LEGATR than in the LEGNOR, although the peak AT force and stiffness were smaller in the LEGATR than in the LEGNOR. The AT negative mechanical work did not show any significant differences between both legs. However, positive works were significantly lower in the LEGATR than in the LEGNOR. Electromyogram patterns in both soleus and tibialis anterior muscles clearly differed after ground contact for the LEGATR and the LEGNOR. These results suggest that the repaired ruptured AT can be compliant and have insufficient Young's modulus, which can influence mechanical responses in muscle activities. The modulation of agonist-antagonist muscle activities corresponding to the different levels of stiffness between the LEGATR and the LEGNOR may not be fully functioning during the pre-activation phase.

    Extensor tendon ruptures in the rheumatoid wrist are usually restored by extensor tendon reconstruction surgery. However, the factors significantly correlated with the outcomes of extensor tendon reconstruction have not been defined. We examined factors showing a statistically significant correlation with postoperative active motion after tendon reconstruction. Spontaneous extensor tendon ruptures of 66 wrists in patients (mean age, 52.6 yrs) with rheumatoid arthritis (RA) were evaluated. All patients underwent tendon reconstruction surgery with wrist arthroplasty or arthrodesis. Active ranges of motion of the affected fingers were evaluated at 12 weeks postsurgery. Statistical significance was determined using multiple and single regression analyses. Forty-six (69.6%) wrists had "good" results, while 13 (19.7%) and 7 (10.6%) wrists had "fair" and "poor" results, respectively. In multiple regression analysis, an increased number of ruptured tendons and the age at operation were independent variables significantly correlated with the postoperative active motion of reconstructed tendons (p = 0.009). Single regression analysis also showed a significant association between the number of ruptured tendons and surgical delay (p = 0.02). The number of ruptured extensor tendons was significantly correlated with the results of tendon reconstruction, and the number of ruptured tendons was significantly correlated with preoperative surgical delay. Our results indicate that, in patients presenting with possible finger extensor tendon rupture, rheumatologists should consult with hand surgeons promptly to preserve hand function.

    2012-01-01

    Since its first description in the 1950s, the pathophysiology of hypertrophic cardiomyopathy has been clarified by advanced echocardiographic technologies. Improved pharmacotherapy now successfully treats most afflicted individuals. Along with these advances, surgical management has also evolved, as the role of the mitral valve and the subvalvular structures in causing obstruction has been identified. Over the last 2 decades, a variety of options to surgically manage the complex patient with obstruction have been described. Successful surgical management is dependent on the complete evaluation of the causes of obstruction in the specific individual, as the heterogeneity of the anatomy may confound the direction of therapy. Mitral valve replacement may no longer be necessary in individuals who have a relatively thin septum and instead obstruct from an elongated mitral anterior leaflet or the presence of accessory papillary muscles and chords. Techniques for mitral valve plication have been successfully used with mid- to long-term success. A systematic strategy for the evaluation of obstruction in hypertrophic cardiomyopathy and the various surgical options are summarized in a procedure termed RPR for resection (extended myectomy), plication (mitral valve shortening), and release (papillary muscle manipulation).

    Full Text Available Abstract Background Coarctation of the aorta in the adulthood is sometimes associated with additional cardiovascular pathologies that require intervention. Ideal approach in such patients is uncertain. Anatomic left-sided short aortic bypass from the arcus aorta to descending aorta via median sternotomy allows simultaneuos repair of both complex aortic coarctation and concomitant cardiac operation. Materials Four adult patients were underwent Anatomic left-sided short aortic bypass operation for complex aortic coarctation through median sternotomy using deep hypothermic circulatory arrest. Concomitant cardiac operations were Bentall procedure for annuloaortic ectasia in one patient, coronary artery bypass grafting for three vessel disease in two patient, and patch closure of ventricular septal defect in one patient. Results All patients survived the operation and were alive with patent bypass at a mean follow-up of 36 months. No graft-related complications occurred, and there were no instances of stroke or paraplegia. Conclusion We conclude that single-stage repair of adult aortic coarctation with concomitant cardiovascular lesions can be performed safely using this newest technique.

    Study Design Case report. Background Acute traumatic avulsion of the rectus abdominis and adductor longus is rare. Chronic groin injuries, often falling under the athletic pubalgia spectrum, have been reported to be more common. There is limited evidence detailing the comprehensive rehabilitation and return to sport of an athlete following surgical or conservative treatment of avulsion injuries of the pubis or other sports-related groin pathologies. Case Description A 29-year-old National Basketball Association player sustained a contact injury during a professional basketball game. This case report describes a unique clinical situation specific to professional sport, in which a surgical repair of an avulsed rectus abdominis and adductor longus was combined with a multimodal impairment- and outcomes-based rehabilitation program. Outcomes The patient returned to in-season competition at 5 weeks postoperation. Objective measures were tracked throughout rehabilitation and compared to baseline assessments. Measures such as the Copenhagen Hip and Groin Outcome Score and numeric pain-rating scale revealed progress beyond the minimal important difference. Discussion This case report details the clinical reasoning and evidence-informed interventions involved in the return to elite sport. Detailed programming and objective assessment may assist in achieving desired outcomes ahead of previously established timelines. Level of Evidence Therapy, level 4.

    Mesh placement during repair of acutely incarcerated ventral and groin hernias is associated with high rates of surgical site infection (SSI). The utility of preoperative computed tomography (CT) in this setting is unclear. We hypothesized that CT evidence of bowel wall compromise would predict SSI while accounting for physiologic parameters. We performed a 4-year retrospective cohort analysis of 50 consecutive patients who underwent mesh repair of acutely incarcerated ventral or groin hernias. We analyzed chronic disease burden, acute illness severity, CT findings, operative management, and herniorrhaphy-specific outcomes within 180 days. The primary outcome was SSI by the Centers for Disease Control and Prevention criteria. Multiple logistic regression was performed to identify independent predictors of SSI. Eighty-four percent of all patients were American Society of Anesthesiologists class III or IV, 28% were active smokers, and mean body mass index (BMI) was 35 kg/m. Fifty-four percent had ventral hernias, 40% had inguinal hernias, and 6% had femoral or combined inguinal/ femoral hernias. Seventy percent of preoperative CT scans had features suggesting bowel compromise, abdominal free fluid, or fluid in the hernia sac. Surgical site infection occurred in 32% of all patients (8% superficial, 24% deep or organ/space). The strongest predictors of SSI were CT evidence of fluid in the hernia sac (odds ratio [OR], 8.3; 95% confidence interval [CI], 1.7-41), initial heart rate 90 beats/min or greater (OR, 6.3; 95% CI, 1.1-34), and BMI 35 kg/m or greater (OR, 5.8; 95% CI, 1.2-28). Surgical site infection rates were significantly higher among patients who had CT evidence of fluid in the hernia sac (56% vs. 19%, p = 0.012). More than half of all patients with CT scan evidence of fluid in the hernia sac developed an SSI. Computed tomography evidence of fluid in the hernia sac was the strongest predictor of SSI, followed by heart rate and BMI. Together, these parameters

    Full Text Available Primitive neuroectodermal tumor in the zygomaticoorbital region is a rare neoplasm of the head and neck. Due to the necessity for wide radical excision of a primary tumor, there may be serious functional and cosmetic disorders that substantially affect quality of life in patients. Restoration of this region is one of the challenges of reconstructive surgery because of the specific features of the relief of bone structures. The paper describes a clinical case of the site of primitive neuroectodermal tumor in the zygomaticoorbital complex and a method for repairing postresectional defect and completely recovering the function of the organ of vision and aesthetic parameters of the face.

    We report the successful repair of impending rupture of a pseudoaneurysm of the brachiocephalic artery (BCA) in a 70-year-old man. He had undergone a mediastinal tumor resection through a median sternotomy in 1995. Pathological examination revealed non-Hodgkin's lymphoma. Two years later, he underwent radiation therapy of 65 Gray for metastasis to the supraclavicular lymph nodes. On January 18, 2000, plastic surgeons planned to perform a pectoralis major musculocutaneous flap to repair a radiation skin ulcer. During the operation, the BCA was lacerated, possibly in an area of radiation tissue damage. We performed a prosthetic graft (10-mm Gelseal) replacement of the BCA. The right subclavian artery had to be ligated. Postoperative digital subtraction angiography (DSA) showed excellent reconstruction of the artery. Magnetic resonance angiography of the brain showed a deficit in the anterior communicating artery and stenosis of the posterior communicating artery, which indicated that the reconstruction procedure was reasonable. Seven months later, on August 18, 2000, the patient was transferred to our hospital because of swelling of the right neck and oozing from the previous cutaneous wound. CT scan and DSA demonstrated the presence of a pseudoaneurysm of the proximal anastomosis site, which required emergency surgery. Before this third sternotomy, a saphenous vein graft was interposed between both external carotid arteries. Removal of the prosthetic graft and resection of the pseudoaneurysm were performed under mild hypothermia and cardiopulmonary bypass with left common carotid arterial perfusion. Then, the wound was closed completely using a left pectoralis major musculocutaneous flap. The postoperative course was uneventful and DSA showed good patency of the graft and intracranial arteries. The patient was discharged without neurological complications. We conclude that prior reconstruction of the carotid artery is a safe and effective procedure for patients

  13. Mesenchymal stem cell therapy regenerates the native bone-tendon junction after surgical repair in a degenerative rat model.

    Full Text Available BACKGROUND: The enthesis, which attaches the tendon to the bone, naturally disappears with aging, thus limiting joint mobility. Surgery is frequently needed but the clinical outcome is often poor due to the decreased natural healing capacity of the elderly. This study explored the benefits of a treatment based on injecting chondrocyte and mesenchymal stem cells (MSC in a new rat model of degenerative enthesis repair. METHODOLOGY: The Achilles' tendon was cut and the enthesis destroyed. The damage was repaired by classical surgery without cell injection (group G1, n = 52 and with chondrocyte (group G2, n = 51 or MSC injection (group G3, n = 39. The healing rate was determined macroscopically 15, 30 and 45 days later. The production and organization of a new enthesis was assessed by histological scoring of collagen II immunostaining, glycoaminoglycan production and the presence of columnar chondrocytes. The biomechanical load required to rupture the bone-tendon junction was determined. PRINCIPAL FINDINGS: The spontaneous healing rate in the G1 control group was 40%, close to those observed in humans. Cell injection significantly improved healing (69%, p = 0.0028 for G2 and p = 0.006 for G3 and the load-to-failure after 45 days (p<0.05 over controls. A new enthesis was clearly produced in cell-injected G2 and G3 rats, but not in the controls. Only the MSC-injected G3 rats had an organized enthesis with columnar chondrocytes as in a native enthesis 45 days after surgery. CONCLUSIONS: Cell therapy is an efficient procedure for reconstructing degenerative entheses. MSC treatment produced better organ regeneration than chondrocyte treatment. The morphological and biomechanical properties were similar to those of a native enthesis.

    Abstract Objective: To evaluate 3D lip morphology, following primary reconstruction in children with unilateral cleft lip and palate (UCLP) relative to contemporaneous non-cleft data Design: Prospective, cross-sectional, controlled study Setting: Glasgow Dental Hospital & School, University of Glasgow, The UK. Patients and Participants: Two groups of 3-year old children (21 with unilateral cleft lip and palate and 96 controls) with facial images taken using a 3D vision based capture technique. Methods: 3D images of the face were reflected so the cleft was on the left side to create a homogenous group for statistical analysis. Three-dimensional co-ordinates of anthropometric landmarks were extracted from facial images. 3D generalised Procustes superimposition was employed and a set of linear measurements were utilised to compare between cleft and control subjects for right and left sides, adjusting for sex differences. Results: Christa philteri on both the cleft and non-cleft sides were displaced laterally and posteriorly; there was also a statistically significant increase in philtrum width. No significant differences between cleft and control regarding the cutaneous height of the upper lip. The lip in the cleft cases was flatter than in the non-cleft cases with less prominence of labialis superioris. Conclusions: Stereophotogrammetry allows detection of residual dysmorphology following cleft repair. There was significant increase of the philtrum width. The lip appeared flatter and more posterior displaced in Unilateral Cleft Lip and Palate (UCLP) cases compared with control. Keywords: child, cleft lip and palate, lip repair, three-dimensional imaging.

    Mitral regurgitation (MR) is a common heart-valve lesion after myocardial infarction in humans. Because it is considered a risk factor for accelerated heart failure and death, various surgical approaches and catheter-based devices to correct it are in development. Lack of a reproducible animal model of MR after myocardial infarction and reliable techniques to perform open-heart surgery in these diseased models led to the use of healthy animals to test new devices. Thus, most devices that are deemed safe in healthy animals have shown poor results in human efficacy studies, hampering progress in this area of research. Here we report our experience with a swine model of postinfarction MR, describe techniques to induce regurgitation and perform open-heart surgery in these diseased animals, and discuss our outcomes, complications, and solutions.

    A 2.5-month-old female patient presented for closure of a ventricular septal defect (VSD). Transthoracic echocardiography showed a large muscular ventricular septal defect. After perventricular closure of the defect was performed with an Amplatzer muscular VSD occluder, peroperative transesophageal echocardiography revealed that the device had been implanted in the wrong area of the ventricular septum. The device was retrieved and a large mid-muscular defect with extension to the outlet septum was closed with a patch of Dacron which was secured with 5-0 sutures. A perforation in the ventricular septum due to attempted perventricular device delivery was seen, and it was repaired primarily. In the eighth month of follow-up, transthoracic echocardiography revealed an aneurysm in the posterior wall of the left ventricle. The patient's electrocardiogram showed pathological Q waves and ST-segment elevation in leads DII, DIII, and aVF consistent with subacute inferior myocardial infarction. At subsequent surgery, this was found to be a true aneurysm, located in area of distribution of the obtuse marginal branch of the left circumflex coronary artery in the posterior wall of the left ventricle. The aneurysm was closed off using a Dacron patch, and the sac was resected. Development of a true aneurysm is a rare but important complication of attempted perventricular VSD closure.

    2007-02-01

    Full Text Available Background:The cosmetic result of the surgical scar has long been considered by surgeons as an important factor for patient satisfaction.On the other hand,there has been an old teaching that perfect closure of contaminated wounds increases the rate of infection. We decided to look into this matter and see if this is a fact or a myth. Methods: In this prospective randomized study conducted on 200 patients with suppurative or gangrenous appendicitis,we closed the wounds with a cosmetic subcuticular suture of 4/0 nylon in 100 patients and in the other 100 patients the wound was approximated loosely with a few stitches of 3/0 nylon in vertical mattress fashion during a 14-month period.Results:There was no significant difference in the rate of wound infection between these two groups.Conclusions:This study shows that perfect closure of the wound with subcuticular closure,which gives a very good cosmetic result in comparison with traditional loose closure, does not increase the rate of wound infection.

    2012-06-01

    Case report. The Achilles tendon is the most frequently ruptured tendon, and the incidence of Achilles tendon rupture has increased in the last decade. The rupture generally occurs without any preceding warning signs, and therefore preinjury data are seldom available. This case represents a unique opportunity to compare preinjury running mechanics with postinjury evaluation in a patient with an Achilles tendon rupture. A 23-year-old female sustained a right complete Achilles tendon rupture while playing soccer. Running mechanics data were collected preinjury, as she was a healthy participant in a study on running analysis. In addition, patient-reported symptoms, physical activity level, strength, ankle range of motion, heel-rise ability, Achilles tendon length, and running kinetics were evaluated 1 year after surgical repair. During running, greater ankle dorsiflexion and eversion and rearfoot abduction were noted on the involved side postinjury when compared to preinjury data. In addition, postinjury, the magnitude of all kinetics data was lower on the involved limb when compared to the uninvolved limb. The involved side displayed differences in strength, ankle range of motion, heel rise, and tendon length when compared to the uninvolved side 1 year after injury. Despite a return to normal running routine and reports of only minor limitations with running, considerable changes were noted in running biomechanics 1 year after injury. Calf muscle weakness and Achilles tendon elongation were also found when comparing the involved and uninvolved sides.

    Fecal incontinence after the surgical repair of Hirschsprung disease is a potentially preventable complication that carries a negative impact on patient's quality of life. Patients that were previously operated for Hirschsprung disease and presented to our bowel management clinic with the complaint of fecal incontinence were retrospectively reviewed. All patients underwent a rectal examination under anesthesia looking for anatomic explanations for their incontinence. One hundred three patients were identified. 54 patients had a damaged anal canal. 22 patients also had a patulous anus. The operative reports mentioned the pectinate line in 32 patients, in 12 it was not mentioned, and in 10 patients the operative report was not available. All patients with a damaged anal canal suffered from true fecal incontinence; 45 of them are on daily enemas (41 are clean and 4 are still having "accidents"), 7 are not doing bowel management due to noncompliance and 2 patients have a permanent ileostomy. 49 patients did not have a damaged anal canal, 25 of those responded to changes in diet and medication and are having voluntary bowel movements. Fecal incontinence may occur after an operation for Hirschsprung disease. When the anal canal is damaged, incontinence is always present, severe, and probably permanent. The preservation of the anal canal may avoid this complication. Copyright © 2017. Published by Elsevier Inc.

    We describe a novel non surgical technique to maintain oxygenation and ventilation in a case of difficult intubation and difficult ventilation, which works especially well with poor mask fit. Can not intubate, can not ventilate" (CICV) is a potentially life threatening situation. In this video we present a simulation of the technique we used in a case of CICV where oxygenation and ventilation were maintained by inserting an endotracheal tube (ETT) nasally down to the level of the naso-pharynx while sealing the mouth and nares for successful positive pressure ventilation. A 13 year old patient was taken to the operating room for incision and drainage of a neck abscess and direct laryngobronchoscopy. After preoxygenation, anesthesia was induced intravenously. Mask ventilation was found to be extremely difficult because of the swelling of the soft tissue. The face mask could not fit properly on the face due to significant facial swelling as well. A direct laryngoscopy was attempted with no visualization of the larynx. Oxygen saturation was difficult to maintain, with saturations falling to 80%. In order to oxygenate and ventilate the patient, an endotracheal tube was then inserted nasally after nasal spray with nasal decongestant and lubricant. The tube was pushed gently and blindly into the hypopharynx. The mouth and nose of the patient were sealed by hand and positive pressure ventilation was possible with 100% O2 with good oxygen saturation during that period of time. Once the patient was stable and well sedated, a rigid bronchoscope was introduced by the otolaryngologist showing extensive subglottic and epiglottic edema, and a mass effect from the abscess, contributing to the airway compromise. The airway was secured with an ETT tube by the otolaryngologist.This video will show a simulation of the technique on a patient undergoing general anesthesia for dental restorations.

    2007-06-01

    Full Text Available Abstract Background Lung transplantation (LTx is widely accepted as a therapeutic option for end-stage respiratory failure in cystic fibrosis. However, airway complications remain a major cause of morbidity and mortality in these patients, serious airway complications like bronchopleural fistula (BPF are rare, and their management is very difficult. Case presentation A 47-year-old man with end-stage respiratory failure due to cystic fibrosis underwent bilateral sequential lung transplantation. Severe post-operative bleeding occurred due to dense intrapleural adhesions of the native lungs. He was re-explored and packed leading to satisfactory haemostasis. He developed a bronchopleural fistula on the 14th post-operative day. The fistula was successfully repaired using pericardial and intercostal vascular flaps with veno-venous extracorporeal membrane oxygenator (VV-ECMO support. Subsequently his recovery was uneventful. Conclusion The combination of pedicled intercostal and pericardial flaps provide adequate vascular tissue for sealing a large BPF following LTx. Veno-venous ECMO allows a feasible bridge to recovery.

    Peripheral nerve injuries with large gaps and long nerve regrowth paths are difficult to repair using existing surgical techniques, due to nerve degeneration and muscle atrophy. This paper proposes a Bionic Neural Link (BNL) as an alternative way for peripheral nerve repair. The concept of the BNL is described, along with the hypothetical benefits. A prototype monolithic single channel BNL has been developed, which consists of 16 neural recording channels and one stimulation channel, and is implemented in a 0.35-µm CMOS technology. The BNL has been tested in in-vivo animal experiments. Full function of the BNL chip has been demonstrated.

    2014-11-15

    Rectovaginal fistula is a disastrous complication of Crohn's disease (CD) that is exceedingly difficult to treat. It is a disabling condition that negatively impacts a women's quality of life. Successful management is possible only after accurate and complete assessment of the entire gastrointestinal tract has been performed. Current treatment algorithms range from observation to medical management to the need for surgical intervention. A wide variety of success rates have been reported for all management options. The choice of surgical repair methods depends on various fistula and patient characteristics. Before treatment is undertaken, establishing reasonable goals and expectations of therapy is essential for both the patient and surgeon. This article aims to highlight the various surgical techniques and their outcomes for repair of CD associated rectovaginal fistula.

    Determining safe surgical access to the orbit can be difficult given the complex anatomy and delicacy of the orbital structures. When considering biopsy or removal of an orbital tumor or repair of orbital fractures, careful planning is required to determine the ideal approach. Traditionally, this has at times necessitated invasive procedures with large incisions and extensive bone removal. The purpose of this review was to present newly techniques and devices in orbital surgery that have been reported over the past decade, with aims to provide better exposure and/or minimally invasive approaches and to improve morbidity and/or mortality.

  7. Presentation and Surgical Management of Duodenal Duplication in Adults

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Duodenal duplications in adults are exceedingly rare and their diagnosis remains difficult as symptoms are largely nonspecific. Clinical presentations include pancreatitis, biliary obstruction, gastrointestinal bleeding from ectopic gastric mucosa, and malignancy. A case of duodenal duplication in a 59-year-old female is presented, and her treatment course is reviewed with description of combined surgical and endoscopic approach to repair, along with a review of historic and current recommendations for management. Traditionally, gastrointestinal duplications have been treated with surgical resection; however, for duodenal duplications, the anatomic proximity to the biliopancreatic ampulla makes surgical management challenging. Recently, advances in endoscopy have improved the clinical success of cystic intraluminal duodenal duplications. Despite these advances, surgical resection is still recommended for extraluminal tubular duplications although combined techniques may be necessary for long tubular duplications. For duodenal duplications, a combined approach of partial excision combined with mucosal stripping may offer advantage.

Methods Our center had performed 125 cases of the bilateral cleft lip repair from Sep 2007 to Sep 2011. Eighteen cases found with asymmetrical bilateral cleft lip were chosen, of which 6 were accompanied by recessive cleft lip. Among the 6 cases, 3 cases were repaired in only one operation, using the technique of unilateral cleft lip repair to fix both sides of the clefts respectively. First the greater side was repaired and then the contralateral side with the recessive cleft lip was repaired. Two cases were repaired by using the technique of bilateral complete cleft lip repair, and one case was repaired only on the greater side and left the recessive side undone. Results The 3 cases achieved satisfactory results by showing good postoperative appearances of the vermillion and philtrum after one to three months' follow-up. The 2 cases showed a tight upper lip with an obvious scar formation on the labial region and a

    2017-06-01

    Abdominal intercostal hernia is an uncommon phenomenon, reported in few case reports and small case series. If left untreated, it can lead to strangulation and visceral ischemia. Prompt diagnosis and appropriate surgical intervention are thus critical to prevent resulting morbidity. We present a 50-year-old woman with a large abdominal intercostal hernia after an open nephrectomy. She underwent a successful robotic repair of the hernia with mesh placement. Through the presentation, we would like to raise awareness of intercostal hernia as a complication of open nephrectomy and significance of early diagnosis in avoiding potential morbidity. We also performed a review of literature especially focusing on acquired abdominal intercostal hernia secondary to prior surgery. Although intercostal hernias can be difficult to repair secondary to the size and location, adequate visualization and surgical planning are critical to successful repair.

    The treatment of bone loss due to different etiologic factors is difficult and many techniques aim to improve repair, including a wide range of biomaterials and, recently, phototherapies. This work assessed, by Raman spectroscopy and histology, the mineralization of bone defects. Forty rats divided into 4 groups each subdivided into 2 subgroups according to the time of sacrifice were used. Bone defects were made on the femur of each animal with a trephine drill. On animals of group Clot the defect was filled only by blood clot, on group Laser the defect filled with the clot was further irradiated. On animals of groups Biomaterial and Laser + Biomaterial the defect was filled by biomaterial and the last one was further irradiated (λ780 nm, 70 mW, Φ ~ 0.4 cm2, 20 J/cm2-session, 140 J/cm2-treatment). At both 15th and 30th days following sacrifice, samples were taken and analyzed by Raman spectroscopy and light microscopy. Raman peaks of inorganic and organic contents and a more advanced stage of repair were seen on group Laser + Biomaterial. It is concluded that the use of Laser phototherapy associated to biomaterial was effective to improve the repair of bone defects.

    Objective: Describe the local morphological response of the articular–epiphyseal cartilage complex to surgical stab incision in the distal femur of foals, with emphasis on the relationship between growth cartilage injury, enchondral ossification, and repair. Design: Nine foals were induced into general anesthesia at the age of 13 to 15 days. Four full-thickness stab incision defects were created in the cartilage on the lateral aspect of the lateral trochlear ridge of the left distal femur. Follow-up examination was carried out from 1 to 49 days postoperatively, including examination of intact bones, sawed slabs, and histological sections. Results: Incision defects filled with cells displaying fibroblast-, chondrocyte-, and osteoblast-like characteristics, potentially validating the rationale behind the drilling of stable juvenile osteochondritis dissecans lesions in children. Incisions induced necrosis within the cartilage on the margins at all depths of the defects. Sharp dissection may therefore be contraindicated in cartilage repair in young individuals. Incisions caused a focal delay in enchondral ossification in 2 foals, apparently related to the orientation of the incision defect relative to the direction of ossification. Defects became progressively surrounded by subchondral bone, in which granulation tissue containing clasts and foci of osteoblast-like cells was observed. Continued enchondral ossification was therefore likely to result in healing of uncomplicated defects to morphologically normal bone. Conclusions: Epiphyseal growth cartilage injury had the potential to exert a negative effect on enchondral ossification. Enchondral ossification exerted a beneficial effect on repair. This relationship warrants consideration in future studies of cartilage injury and repair within the articular–epiphyseal cartilage complex of all species. PMID:26069670

    Various techniques have been described for unilateral cleft lip repair. These may be broadly classified into three types of procedure/concept: the straight-line method (SL; Rose-Thompson effect); rotation-advancement (RA; upper-lip Z-plasty); and the triangular flap method (TA; lower-lip Z-plasty). Based on these procedures, cleft lip repair has evolved in recent decades. The cleft lip repair method in our institution has also undergone several changes. However, we have found that further modifications are needed for Asian patients who have wider philtral dimples and columns than Caucasians, while following the principles of the original techniques mentioned above. Here, we have incorporated the advantages of each procedure and propose a refined hybrid operating technique, seeking a more appropriate procedure for Asian patients. To evaluate our new technique, a comparison study was performed to evaluate RA, SL, and our technique. We have used our new technique to treat 137 consecutive cleft lip cases of all types and degrees of severity, with or without a cleft palate, since 2009. In the time since we adopted the hybrid technique, we have observed improved esthetics of the repaired lip. Our technique demonstrated higher glance impression average scores than RA/SL.

    2014-01-01

    Full Text Available Background. When implementing a new surgical technique, the best method for didactic learning has not been settled. There are basically two scenarios: the trainee goes to the teacher’s clinic and learns the new technique hands-on, or the teacher goes to the trainee’s clinic and performs the teaching there. Methods. An informal literature review was conducted to provide a basis for discussing pros and cons. We also wanted to discuss how many surgeons can be trained in a day and the importance of the demand for a new surgical procedure to ensure a high adoption rate and finally to apply these issues on a discussion of barriers for adoption of the new ONSTEP technique for inguinal hernia repair after initial training. Results and Conclusions. The optimal training method would include moving the teacher to the trainee’s department to obtain team-training effects simultaneous with surgical technical training of the trainee surgeon. The training should also include a theoretical presentation and discussion along with the practical training. Importantly, the training visit should probably be followed by a scheduled visit to clear misunderstandings and fine-tune the technique after an initial self-learning period.

    Objective The technique of endovascular repair for type B aortic dissection has been widely used because of its advantage of low invasiveness and safety.But the complication of Stanford A dissection during and after this operation owing to retrograde tearing should be highly noticed because of its high mortality despite rarely happened.The present study retrospectively analyzed 11 cases of retrograde type A aortic dissection after endovascular repair for type B aortic dissection.The characteristics and surgical intervention for these cases were summarized.Methods From April 2005 to March 2008,eleven cases of retrograde type A aortic dissection after endovascular repair for type B aortic dissection were treated.Among diem,7 cases occurred within 3 months after endovascular repair,the intimal tear of the dissection all happened near ihe proximal end of the stent graft and the distal end of the vascular prosthesis was all anastomosed with the stent graft.The other 4 cases happened longer than 3 months after endovascular repair.Neither did the intimal tear of the dissection nor the distal end of the vascular prosthesis correlate with the stent graft.All the patients received median stemotomy incision.Selective cerebral perfusion through right axillary artery under deep hypothenm'c circulation arrest were used when operating on aortic arch.Results All the cases recovered and were alive after following 7 to 40 months.No serious complications such as stroke,paraplegia or renal failure were found.Conclusion Retrograde type A aortic dissection happened shortly (within 3 months) after endovascular repair may be correlated with stent insertion.The vascular prosthesis can be directly anastomosed with the stent graft.It remains to be further studied whether retrograde type A aortic dissection happened longer after endovascular repair is related with the operation.Favorable effect can be achieved for this kind of patients by surgical treatment.Satisfied cerebral protection and

    Surgical cleft repair aims to restore function of the oro-nasal sphincter and oro-nasal soft tissues and re-establish the complex relationship between perioral and perinasal muscle rings without compromising subsequent mid-facial growth and development. Here we review the surgical anatomy of this region, optimal timing for surgical repair and current thinking on the use of surgical adjuncts. In addition, an overview of current surgical techniques available for the repair of cleft lip, cleft palate and velopharyngeal insufficiency is presented. Finally, we briefly discuss nasal revision surgery and the use of osteotomy, including distraction osteogenesis in the cleft patient.

  19. Compartment Syndrome following Open Femoral Fracture with an Isolated Femoral Vein Injury Treated with Acute Repair

    Directory of Open Access Journals (Sweden)

    David Walmsley

    2014-01-01

    Full Text Available Acute compartment syndrome is a surgical emergency and its diagnosis is more difficult in obtunded or insensate patients. We present the case of a 34-year-old woman who sustained a Gustilo-Anderson grade III open midshaft femur fracture with an isolated femoral vein injury treated with direct repair. She developed lower leg compartment syndrome at 48 hours postoperatively, necessitating fasciotomies. She was subsequently found to have a DVT in her femoral vein at the level of the repair and was started on therapeutic anticoagulation. This case highlights the importance of recognition of isolated venous injuries in a trauma setting as a risk factor for developing compartment syndrome.

    Esophageal perforation due to blunt trauma is a rare clinical condition, and the diagnosis is often difficult because patients have few specific symptoms. Delayed diagnosis may result in a fatal clinical course due to mediastinitis and subsequent sepsis. In this article, we describe a 26-year-old man with esophageal perforation due to blunt chest trauma resulting from a motor vehicle accident. Because a severe disturbance of consciousness masked the patient's trauma-induced thoracic symptoms, we required 11h to diagnose the esophageal perforation. Therefore, the patient developed septic shock due to mediastinitis. However, his subsequent clinical course was good because of prompt combined therapy involving surgical repair and medical treatment after the diagnosis. Copyright © 2017 Elsevier Inc.

    2012-09-01

    Patients with repaired tetralogy of Fallot are monitored for pulmonary regurgitation (PR) and right ventricular (RV) function. We sought to compare measures of PR and RV function on echocardiogram to those on cardiac magnetic resonance (CMR) and to develop a new tool for assessing PR by echocardiogram. Patients with repaired tetralogy of Fallot (n=143; 12.5±3.2 years) had an echocardiogram and CMR within 3 months of each other. On echocardiogram, RV function was assessed by (1) Doppler tissue imaging of the RV free wall and (2) myocardial performance index. The ratio of diastolic and systolic time-velocity integrals measured by Doppler of the main pulmonary artery was calculated. CMR variables included RV ejection fraction, RV volumes, and pulmonary regurgitant fraction (RF). Pulmonary regurgitation was graded as mild (RF40%). On CMR, RF was 34+17% and RV ejection fraction was 61+8%. Echocardiography had good sensitivity identifying cases with RF>20% (sensitivity 97%; 95% CI: 92-99%) but overestimated the amount of PR when RFPR in patients with repaired tetralogy of Fallot and warrants further investigation. However, echocardiography continues to have a limited ability to quantify PR and RV function as compared with CMR.

    To compare 256-slice cardiac computed tomography (CCT) with cardiac magnetic resonance (CMR) imaging to assess right ventricular (RV) function and pulmonary regurgitant fraction (PRF) in patients with repaired tetralogy of Fallot (TOF). Thirty-three consecutive patients with repaired TOF underwent retrospective ECG-gated CCT and 3-Tesla CMR. RV and left ventricular (LV) end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and ejection fraction (EF) were measured using CCT and CMR. PRF-CCT (%) was defined as (RVSV - LVSV)/RVSV. PRF-CMR (%) was measured by the phase-contrast method. Repeated measurements were performed to determine intra- and interobserver variability. CCT measurements, including PRF, correlated highly with the CMR reference (r = 0.71-0.96). CCT overestimated RVEDV (mean difference, 17.1 ± 2.9 ml), RVESV (12.9 ± 2.1 ml) and RVSV (4.2 ± 2.0 ml), and underestimated RVEF (-2.6 ± 1.0 %) and PRF (-9.1 ± 2.0 %) compared with CMR. The limits of agreement between CCT and CMR were in a good range for all measurements. The variability in CCT measurements was lower than those in CMR. The estimated effective radiation dose was 7.6 ± 2.6 mSv. 256-slice CCT can assess RV function and PRF with relatively low dose radiation exposure in patients with repaired TOF, but overestimates RV volume and underestimates PRF.

    Clefts of the sternum have always attracted attention whether for pathological and physiological features or for research of surgical correction. Two cases of sternal cleft, one with partial ectopia cordis, the other with Cantrell's pentalogy, are presented. Embryology, strategies and several surgical techniques are discussed on the grounds of personal experience. The pediatric surgeon can make a choice among a lot of surgical techniques, because the ectopia cordis and Cantrell's pentalogy are very uncommon and the surgical treatment has a difficult codification. The knowledge of several methods of surgical correction is necessary to reduce high mortality of ectopia cordis and Cantrell's pentalogy. Primary repair in the neonatal period is the best type of management for these rare conditions, because simple closure of the sternal defect during the first month of life avoids the more complex reconstruction necessary in older children.

    Rectovaginal fistula is a disastrous complication of Crohn’s disease(CD) that is exceedingly difficult to treat. It is a disabling condition that negatively impacts a women’s quality of life. Successful management is possible only after accurate and complete assessment of the entire gastrointestinal tract has been performed. Current treatment algorithms range from observation to medical management to the need for surgical intervention. A wide variety of success rates have been reported for all management options. The choice of surgical repair methods depends on various fistula and patient characteristics. Before treatment is undertaken, establishing reasonable goals and expectations of therapy is essential for both the patient and surgeon. This article aims to highlight the various surgical techniques and their outcomes for repair of CD associated rectovaginal fistula.

    The purpose was to evaluate the relative glycosaminoglycan (GAG) content of repair tissue in patients after microfracturing (MFX) and matrix-associated autologous chondrocyte transplantation (MACT) of the knee joint with a dGEMRIC technique based on a newly developed short 3D-GRE sequence with two flip angle excitation pulses. Twenty patients treated with MFX or MACT (ten in each group) were enrolled. For comparability, patients from each group were matched by age (MFX: 37.1 {+-} 16.3 years; MACT: 37.4 {+-} 8.2 years) and postoperative interval (MFX: 33.0 {+-} 17.3 months; MACT: 32.0 {+-} 17.2 months). The {delta} relaxation rate ({delta}R1) for repair tissue and normal hyaline cartilage and the relative {delta}R1 were calculated, and mean values were compared between both groups using an analysis of variance. The mean {delta}R1 for MFX was 1.07 {+-} 0.34 versus 0.32 {+-} 0.20 at the intact control site, and for MACT, 1.90 {+-} 0.49 compared to 0.87 {+-} 0.44, which resulted in a relative {delta}R1 of 3.39 for MFX and 2.18 for MACT. The difference between the cartilage repair groups was statistically significant. The new dGEMRIC technique based on dual flip angle excitation pulses showed higher GAG content in patients after MACT compared to MFX at the same postoperative interval and allowed reducing the data acquisition time to 4 min.

    Full Text Available Ebstein′s anomaly (EA is the most common cause of congenital tricuspid regurgitation. The associated anomalies commonly seen are atrial septal defect or patent foramen ovale and accessory conduction pathways. Its association with coexisting mitral stenosis (MS has uncommonly been described. The hemodynamic consequences and anesthetic implications, of a combination of EA and rheumatic MS, have not so far been discussed in the literature. We report successful anesthetic management of a repair of EA and mitral valve replacement in a patient with coexisting Wolff-Parkinson-White (WPW syndrome.

    2014-09-01

    In general, favorable outcomes have been achieved with arthroscopic repair of superior labral anterior-posterior (SLAP) tears. However, some patients remain dissatisfied or suffer further injury after SLAP repair and may seek additional treatment to alleviate their symptoms. The cause of persistent pain or recurrent symptoms after repair is likely multifactorial; therefore, careful preoperative workup is required to elucidate the cause of pain. Review of the details of previous surgical procedures is crucial because certain fixation methods are prone to failure or can cause additional injury. Failed SLAP repair can be managed with nonsurgical or surgical options. Nonsurgical modalities include physical therapy and strengthening programs, anti-inflammatory agents, and activity modification. Surgical options include revision SLAP repair and biceps tenotomy or tenodesis with or without revision SLAP repair. Outcomes after surgical management of failed SLAP repair are inferior to those of primary repair. Select patients may be better served by primary biceps tenodesis rather than SLAP repair.

    The effectiveness of new therapies to treat tendon injuries is difficult to determine and is often based on semi-quantitative methods, such as grey level analysis of ultrasonographic images or subjective pain scores. The alternatives are costly and long-lasting end-stage studies using experimental animals. In this study, a method of ultrasonographic tissue characterisation (UTC), using mathematical analysis of contiguous transverse ultrasonographic images, was used for intra-vital monitoring of the healing trajectory of standardised tendon lesions treated with platelet rich plasma (PRP) or placebo. Using UTC it was possible to detect significant differences between the groups in the various phases of repair. At end stage, over 80% of pixels showed correct alignment in the PRP group, compared with just over 60% in the placebo group (Ptendon lesions in horses.

    Full Text Available Several factors increase the risk of insicional hernias post-kidney transplantation and different surgical techniques exist for solving this problem. A retrospective study analyzing the risk factors for developing an insicional hernia and eventroplasties made in the kidney transplants performed between 2006-2013 was performed. The incidence of hernias was 12.7%. All elements studied were statistically independent of the appearance of hernias, probably by influence when combined together and not each separately. Consistent with the literature in which patients did not mesh was used or an absorbable mesh used had a recurrence of 100%. It should be more study of the risk factors that influence the development of post-transplant hernias because of the contradictions that arise from the literature. Post-transplant renal ventral hernia repair is safe and effective provided it is carried out for non-resorbable mesh. The risk of post-surgical infections does not appear to be affected by the use of mesh when the necessary precautions are taken, and if it does not change the prognosis.

    the definitive repair is indicated to improve the disease's natural history. However many factors are responsible for a still high surgical mortality in this condition. In the present study the surgical experience in the correction of CAVSD is reviewed in order to identify potential statistically important risk factors for operative death. Between January 1974 and December 1990,52 patients with complete atrioventricular septal defects underwent definitive surgical repair at The Royal Brompton and National Heart and Lung Institute. They were retrospectively studied and the following variables analysed: age, weight, sex, year of the operation, Down's syndrome, atrioventricular valve regurgitation, previous pulmonary artery banding, associated anomalies, systolic pulmonary artery pressure, double "mitral" valve orifice, Rastelli's classification, circulatory arrest, and the surgical technique (1 x 2 patches. All this variables were studied by the univariate analysis and, to determine which factors were independently responsible for the operative risk, multivariate analysis with logistic regression was applied. Multivariate analysis showed that the low weight at operation an 1 patch technique significantly increased surgical mortality.

    2008-01-01

    Surgical repair of postlaryngectomy pharyngocutaneous fistula (PCF) can be challenging. Although several studies describe separate reconstruction methods, only few address the variability in defect characteristics and hence flap selection. The current clinical study presents a retrospective review of 19 patients who underwent surgical repair of persistent PCFs, over a 4-year period in a tertiary referral institute by a single primary surgeon. All but one patient were men with a mean age of 61 +/- 10 years. Nine patients had previous unsuccessful attempts for surgical closure. Previous neck irradiation was the most common comorbid condition encountered (52.6%), followed by low hemoglobin level (47.4%), hepatic disease (36.8%) and diabetes mellitus (31.6%). According to defect characteristics, six patients received a local cervical skin procedure, ten patients had reconstructions using the pectoralis major musculocutaneous flap and three patients required a radial forearm free flap repair. All PCFs were eventually successfully closed with no major complications. Patients were followed-up for an average of 19.7 months (range, 5-38 months). Acceptable oral swallowing results were achieved in all but one patient. In conclusion, successful results are achievable in difficult persistent PCF cases with a defect based reconstruction approach kept in mind.

    A strong interest and need exist in the workplace today to master the skills of conducting difficult conversations. Theories and strategies abound, yet none seem to have found the magic formula with universal appeal and success. If it is such an uncomfortable skill to master is it better to avoid or initiate such conversations with employees? Best practices and evidence-based management guide us to the decision that quality improvement dictates effective communication, even when difficult. This brief paper will offer some suggestions for strategies to manage difficult conversations with employees. Mastering the skills of conducting difficult conversations is clearly important to keeping lines of communication open and productive. Successful communication skills may actually help to avert confrontation through employee engagement, commitment and appropriate corresponding behavior

    Blunt trauma to the thoracic aorta is life-threatening, with instant fatality in at least 75% of victims. If left untreated, nearly half of those who survive the initial injury will die within the first 24 hours. Surgical repair has been the standard treatment of blunt aortic injury, but immediate operative intervention is frequently difficult due to concomitant injuries. Although endovascular treatment of traumatic aortic disruption is less invasive than conventional repair via thoracotomy, this strategy remains controversial in young patients due to anatomical considerations and device limitations. This article reviews the likely advantages of endovascular interventions for blunt thoracic aortic injuries. Potential limitations and clinical outcomes of this minimally invasive technique are also discussed.

Methods 25 patients with reperforation after repair of perforated gastroduodenal ulcer in three hospitals in the past ten years were analyzed retrospectively;and 25 patients without perforation were randomly selected. The influencing factors of reperforation were compared and then analyzed statistically using the Spss 13.0. P<0.05 had significant differences. Results The high-risk factors for influencing reperforation were people aged 60 or older;coexiting diseases including diabetes mellitus,cirrhosis,cor pulmonale,and hypertension;prolonged perforation (equal to or longer than 24 hours);larger perforation (diameter equal to or longer than one centimeter);and obvious scars around the perforated area. Conclusions For the high-risk patients,surgical procedures should be improved to prevent reperforation. If the patient conditions are allowed,subtotal gastrectomy can be performed. The patients generally can be cured by palliative treatment after the occurrence of reperforation.

    To evaluate automated segmentation and the effects of different manual adjustments regarding left ventricular parameter quantification in cardiac magnetic resonance (MR) data on children and adolescents who have undergone surgical repair of right-sided congenital heart disease (CHD). Dedicated software (syngo.via, Siemens AG) was used to automatically segment and/or manually adjust the end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), myocardial mass (MM) and ejection fraction (EF) before/after manual apex/base adjustment (ADJ-step 1) and after manual apex/base/myocardial contour adjustment (ADJ-step 2; reference standard). MR data of 40 patients (13.1 ± 3.1y, 4-17y) with repaired CHD with decreased pulmonary blood flow (CHD-DPBF) were evaluated. Intra- and inter-rater reliability was determined for 10 randomly selected patients. The software correctly detected the left ventricle in 38/40 (95 %) patients. EDV after automated segmentation: 119.1 ± 44.0ml; after ADJ-step 1: 115.8 ± 39.5 ml; after ADJ-step 2: 116.2 ± 39.4 ml. The corresponding results for ESV were 52.0 ± 18.5/49.6 ± 16.9/49.7 ± 16.4 ml; for SV 67.1 ± 28.5/66.2 ± 25.4/66.5 ± 25.5 ml; for EF 55.5 ± 7.3/56.7 ± 6.6/56.7 ± 6.3%; for MM 83.7 ± 35.9/76.2 ± 28.3/74.6 ± 27.2 g. Significant differences were found for ESV/MM/EF comparing the automated segmentation results with these after ADJ-step 1 and ADJ-step 2. No significant differences were found when comparing all results of ADJ-step 1 and ADJ-step 2 or when comparing EDV/SV results. Intra- and inter-rater reliability was excellent. The mean time effort was 63.4 ± 6.9 s for the automated segmentation, 74.2 ± 8.9 s for ADJ-step 1 and 269.5 ± 39.4 s for ADJ-step 2. Automated left ventricular volumes and function analysis in children and adolescents with surgically treated CHD proved to be feasible with excellent intra- and inter-rater reliability. Automated segmentation with manual apex/base adjustment provided

    The two broad categories of fiber-reinforced composite liner repair and deposited weld metal repair technologies were reviewed and evaluated for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Principal conclusions from a survey of natural gas transmission industry pipeline operators can be summarized in terms of the following performance requirements for internal repair: (1) Use of internal repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling when a new bore must be created to solve a leak or other problem. (3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) The most common size range for 80% to 90% of operators surveyed is 508 mm (20 in.) to 762 mm (30 in.), with 95% using 558.8 mm (22 in.) pipe. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without

    To evaluate the efficacy of bovine pericardium (BP) graft in the treatment of deep melting corneal ulcers in three dogs and corneal sequestra in three cats. Three dogs with keratomalacia affecting the deep third of the stroma and three cats with corneal sequestrum were evaluated and underwent surgery. Following keratectomy, BP material was placed into the keratectomy bed and sutured to the recipient cornea with 9/0 polyglactin suture material. Postoperative treatment with topical and systemic antibiotics, systemic nonsteroidal anti-inflammatory agents, and topical atropine was prescribed. Follow-up examinations were carried out 1, 2 weeks, 1 and 2 months after the surgery and consisted of a complete ophthalmic examination. Optical coherence tomography (OCT) was performed 1 and 2 months after the surgery in one dog and in one cat. At 1 week, corneal neovascularization was present around the BP graft in all cases. Four weeks after the BP graft, in two dogs and in all cats, the vascularization was regressing and the graft was integrated into the cornea, which was regaining transparency. Topical treatment with anti-inflammatory agents was then prescribed for 2 weeks. Two months after the surgery, 5 of 6 corneas in two dogs and three cats had healed with focal corneal scarring. The remaining dog had progression of the keratomalacia involving the deep BP graft that required additional surgery, but became blind. Bovine pericardium graft offers a promising option for surgical reconstruction of the cornea following keratectomy for the management of corneal ulcers and sequestra. © 2013 American College of Veterinary Ophthalmologists.

    Rotator cuff tears are a very common condition that is often incapacitating. Whether non-surgical or surgical, successful management of rotator cuff disease is dependent on appropriate rehabilitation. If conservative management is insufficient, surgical repair is often indicated. Postsurgical outcomes for patients having had rotator cuff repair can be quite good. A successful outcome is much dependent on surgical technique as it is on rehabilitation. Numerous rehabilitation protocols for the management of rotator cuff disease are based primarily on clinical experience and expert opinion. This article describes the different rehabilitation protocols that aim to protect the repair in the immediate postoperative period, minimize postoperative stiffness and muscle atrophy. A review of currently available literature on rehabilitation after arthroscopic rotator cuff tear repair was performed to illustrate the available evidence behind various postoperative treatment modalities. There were no statistically significant differences between a conservative and an accelerated rehabilitation protocol . Early passive range of motion (ROM) following arthroscopic cuff repair is thought to decrease postoperative stiffness and improve functionality. However, early aggressive rehabilitation may compromise repair integrity. The currently available literature did not identify any significant differences in functional outcomes and relative risks of re-tears between delayed and early motion in patients undergoing arthroscopic rotator cuff repairs. A gentle rehabilitation protocol with limits in range of motion and exercise times after arthroscopic rotator cuff repair would be better for tendon healing without taking any substantial risks. A close communication between the surgeon, the patient and the physical therapy team is important and should continue throughout the whole recovery process.

  19. Apical vault repair, the cornerstone or pelvic vault reconstruction.

    1997-01-01

    Pelvic organ prolapse remains a difficult problem for pelvic reconstructive surgery. Before new surgical procedures can be developed a good understanding of pelvic anatomy is necessary. It is widely held that the etiology of pelvic organ prolapse is secondary to stretch neuropathy following childbirth and chronic cough or constipation. Several transvaginal and transabdominal procedures have been developed over the years. With the increasing use of laparoscopy, a new variation on existing culdeplasty techniques has been developed. Following anatomical principles, the apical vault repair reestablishes the pericervical ring at the vaginal apex. The incorporation of pubocervical fascia, uterosacral-cardinal ligament and the rectovaginal fascia provides a strong anchor for the vaginal apex. In addition, the repair should help prevent future transverse cystocele, rectocele, enterocele and apical vault prolapse. Early outcome studies suggest that the apical vault repair should be used routinely with laparoscopic urethropexy, laparoscopic hysterectomy and the repair of pelvic organ prolapse. Good apical vault support is considered the cornerstone of pelvic reconstruction.

    Difficult to control severe asthma is characterized by the persistence of inacceptable symptoms of asthma despite a continuous treatment with at least high doses of inhaled steroids and long acting bronchodilators. The diagnosis is done after a period of observation and some investigations that will allow confirm the diagnosis of asthma, eliminate alternative diagnosis and etiological forms that would be difficult to treat intrinsically (allergic broncho-pulmonary aspergillosis, Churg and Strauss disease, chronic eosinophilic pneumonia, occupational asthma). At the end of this period devoted to diagnosis a systematic approach is set up to take care of these patients. Therapeutic education includes action plans and measures for triggering factors avoidance in order to prevent exacerbations. Comorbidities such as rhinitis, nasal polyposis, gastro-oesophageal reflux and obesity are taken into account. Lastly, the treatment must be adapted according to the patient's preferences and aims, and to the asthma severity. Ultimately in steroid-dependent asthma, the lowest efficient dose is tracked continuously. For these patients, new molecules are needed.

    We treated a selected group of children attending a difficult asthma clinic with intramuscular triamcinolone acetonide. This study retrospectively reviews markers of asthma severity in those who received one or more monthly doses for three periods: 1) 3 months preceding the first injection (pretreatment), 2) from the first injection to 1 month after the last injection (treatment period), and 3) 3 months after the treatment period (follow-up period). Severity markers during the treatment and follow-up periods were compared with the pretreatment period by paired t-test. Five children (5-13 years old) received a single dose, and 8 children (12-15 years old) received multiple doses. Multiple doses of triamcinolone (n = 3-5) were associated with a fall in the number of asthma exacerbations (P < 0.01) and hospital admissions (P < 0.01) in both the treatment and follow-up periods. A single dose reduced exacerbations (P < 0.05, treatment vs. pretreatment) but not hospital admissions. We conclude that intramuscular triamcinolone is a useful short-term therapy in difficult asthma. Whether its efficacy is due to improved compliance, or an improved anti-inflammatory profile compared with oral steroids, remains unclear. Copyright 2005 Wiley-Liss, Inc

    Abdominal wall or parastomal hernias following major genitourinary or abdominal surgery are a significant surgical problem. Open surgical repair is difficult because of adhesion formation and poor definition of the hernia fascial edges. Laparoscopic intervention has allowed effective correction of these abdominal wall hernias. From November 1997 to June 2000, 14 male and 3 female patients underwent laparoscopic abdominal wall herniorrhaphy at our institution. Of these, 13 patients received incisional and 4 parastomal hernia repair. All hernia defects were repaired using a measured piece of Gore-Tex DualMesh. A retrospective review of each patient's history and operative characteristics was undertaken. All repairs were successful. No patient required conversion to an open procedure, and there were no intraoperative complications. The average operative time was 4 (range 2.5-6.5) and 4.3 (range 3.75-5.5) hours in the incisional and parastomal group, respectively. The average hospital stay was 4.9 days (range 2-12) for the incisional group and 3.8 (range 3-4) days for the parastomal group. To date, two patients experienced a recurrence of incisional hernias, at 5 and 8 months postoperatively. No recurrences have developed in the parastomal hernia repairs at 2 to 33 months. Laparoscopic repair of abdominal wall incisional or parastomal hernias provides an excellent anatomic correction of such defects. Adhesions are lysed under magnified laparoscopic vision, and the true limits of the fascial defects are clearly identified. The DualMesh is easy to work with and has yielded excellent results. A comparison with open repair with respect to perioperative factors and long-term success is currently under way.

  8. The surgical treatment of cloaca.

    Bischoff, Andrea

    2016-04-01

    Similar to other anorectal malformations, cloaca also represents a spectrum of defects that goes from "benign" cloaca with a good functional prognosis that can be repaired with a relatively simple surgical technique, to very complex malformations with many anatomic variations that require different surgical maneuvers to be able to successfully reconstruct those patients. The group of patients born with a "benign" type of cloaca will have bowel and urinary control, will become sexually active and may get pregnant and deliver by cesarean section. All this is possible, provided the malformation is repaired with a meticulous and delicate technique. Fortunately this represents more than 50% of all cloacas. Our belief is that the surgical technique to repair this group of defects is reproducible and can be taught to pediatric surgical trainees. On the other hand, complex cloaca with a common channel longer than 3 cm should be repaired by surgeons fully dedicated to repair these malformations. The experience reported in this paper is based on 570 patients with cloaca operated by Dr. Alberto Peña and the author in the last 8 years. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND: Scientific approach of the bone reaction after surgical procedures provides valuable information on methods and techniques. The purpose of this study was to follow this process using a radioisotope marker of bone remodelling. MATERIAL AND METHODS: Two bone cavities were created (one for every tibia in adult Wistar male rats using a 0.5 mm spherical burr; left tibial cavities were filled with bovine freeze-dried bone; the right ones were left unfilled for control. Scintigrams were done with sodium methylene diphosphonate (MDP labelled with radioactive pertechnetate (99mTcO4- to evaluate the inflammatory response and the local osteoblastic activity. The evolution of bone repair was additionally evaluated by light microscopy. RESULTS: Our results have shown that the highest bone activity was recorded between the 7th and the 14th day after surgery. The morphological analysis confirmed the results obtained with radioisotope analysis and did not reveal significant differences regarding the evolution of bone repair between the filled and the unfilled defects. CONCLUSION: We confirmed that 99mTc -MDP is a valuable tool to study bone repair, as it was able to show subtle alterations of bone activity even in lesions as small as those created herein (0.5 mm wide, 0.5 mm deep.Este trabalho objetivou estudar a evolução temporal do processo de reparo ósseo em tíbia de rato, após trauma cirúrgico padronizado.

    The two broad categories of deposited weld metal repair and fiber-reinforced composite liner repair technologies were reviewed for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Preliminary test programs were developed for both deposited weld metal repair and for fiber-reinforced composite liner repair. Evaluation trials have been conducted using a modified fiber-reinforced composite liner provided by RolaTube and pipe sections without liners. All pipe section specimens failed in areas of simulated damage. Pipe sections containing fiber-reinforced composite liners failed at pressures marginally greater than the pipe sections without liners. The next step is to evaluate a liner material with a modulus of elasticity approximately 95% of the modulus of elasticity for steel. Preliminary welding parameters were developed for deposited weld metal repair in preparation of the receipt of Pacific Gas & Electric's internal pipeline welding repair system (that was designed specifically for 559 mm (22 in.) diameter pipe) and the receipt of 559 mm (22 in.) pipe sections from Panhandle Eastern. The next steps are to transfer welding parameters to the PG&E system and to pressure test repaired pipe sections to failure. A survey of pipeline operators was conducted to better understand the needs and performance requirements of the natural gas transmission industry regarding internal repair. Completed surveys contained the following principal conclusions: (1) Use of internal weld repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling (HDD) when a new bore must be created

    Introduction: Mucopolysaccharidoses (MPSs) are a group of heredity storage diseases, transmitted in an autosomal recessive manner, associated with the accumulation of glycosaminoglycans (GAGs) in various tissues and organs. The concerned patients have multiple concomitant hereditary anomalies. Considering the craniofacial abnormality in these patients, airway management may be difficult for anesthesiologists. In these patients, preanesthetic assessment is necessary and performed with the accurate assessment of airways, consisting of the physical exam and radiography, MRI or CT of head and neck. An anesthesiologist should set up a “difficult intubation set” with a flexible fiber-optic bronchoscope and also, it may be necessary to discuss with an ear-nose and throat (ENT) specialist if required, for unpredicted emergency situations. Case Presentation: In this case-report we presented a 2-year-old boy with known MPSs with psychomotor retardation, bilateral corneal opacities, impaired hearing and vision, inguinal hernia, severe mitral regurgitation, micrognathia, coarse facial feature, stiff and short neck and restricted mouth opening. He scheduled for left inguinal hernia repair surgery. Discussion: The patient’s difficult airway was managed successfully and the anesthesia of his surgical procedure had an uneventful course.

    Repair for a small (≤2 cm) umbilical and epigastric hernia is a minor surgical procedure. The most common surgical repair techniques are a sutured repair or a repair with mesh reinforcement. However, the optimal repair technique with regard to risk of reoperation for recurrence is not well...... documented. The aim of the present study was in a nationwide setup to investigate the reoperation rate for recurrence after small open umbilical and epigastric hernia repairs using either sutured or mesh repair....

    Full Text Available The anesthesiologist plays a unique role in the health care of all patients who will undergo a surgical procedure. In this sense, he is a key factor in the appropriate and timely management of the airway. There are special situations that condition a difficult airway and can have a profound impact on anesthetic morbidity and mortality. These risks increases in the case of children, that is why the case of a pediatric patient with a difficult airway caused by limitation of mouth opening, scheduled for elective surgery in order to treat this condition in the Pediatric University Hospital ¨Paquito González Cueto " in Cienfuegos, is presented.

    Full Text Available Laryngectomy is always a challenging surgery both from surgical and anaesthesiologist′s perspective. The situation can get worse when such patients present with advanced laryngeal cancerrequire a definite surgical intervention along with thyroid gland removal. Apart from anesthetic difficulties in managing the deranged anatomy and pathophysiology, management of difficult airway during peri-operative period can be a huge challenging task. We are reporting a case of laryngeal carcinoma that was posted for laryngectomy and thyroidectomy as the thyroid gland was also invaded to a small extent. A difficult airway situation was anticipated as during indirect laryngoscopy it was observed that the glottic covering was occluded to a large extent by a soft tissue growth.

    (i) To assess whether mentors had a positive or negative attitude towards their role; and (ii) to discover what aspects of the role they found easy or difficult. The fact that mentorship is an important element in nurse training was recognized by Sir Leonard Peach, the United Kingdom Central Council for Nursing, Midwifery and Health Visiting and the Nursing and Midwifery Council which has recently published new standards to support learning and assessment in practice, which include standards for the preparation of Mentors, to be implemented by September 2007. There are many anecdotal reports of the problems which face mentors, but little firm evidence. This paper reports a study of those problems. It used a Thurstone scale to assess role satisfaction among mentors (n = 86, response rate 89%) and two Likert scales to assess where problems, if any, lay. Unlike anecdotal reports, the Thurstone scale found that, overall, mentors regarded the role positively. In addition, a principal components analysis of responses to the Likert scales showed that there were two clearly delineated factors. The first (interpersonal/organisational factors) had been widely discussed in the literature. The second (cognitive/intellectual factors) has been rarely discussed and could with profit be more strongly stressed in mentor training. (i) Mentors had a positive attitude towards their role and enjoyed it. (ii) When looking at what caused mentors difficulty, in addition to the commonly discussed dimensions of organisational constraints (workload, skill mix) and interpersonal factors, there was clearly an additional cognitive one. Knowledge, not just personality, mattered. Mentors and those who train them could with profit pay more attention to cognitive components of the role, even if that meant laying a lesser stress on the interpersonal ones.

  18. Salvage of a failed open gastrocutaneous fistula repair with an endoscopic over-the-scope clip

    2016-05-01

    Full Text Available Once enteral access via gastrostomy tube (G-tube is no longer indicated, the tube is typically removed in clinic with a high probability of spontaneous closure. When spontaneous closure is not achieved, the formation of a gastrocutaneous fistula (GCF is possible. The incidence of GCF is directly related with the length of time the tube has been placed. When conservative management fails, surgical intervention is the standard treatment. Endoscopic techniques have been described for primary closure of GCF in adults including banding and cauterizing of the fistula tract with placement of a standard endoscopic clip. Over-the-scope clips (OTSC have recently been reported in primary GCF closure in children (Wright et al., 2015. In patients with skin irritation surrounding a GCF making surgical repair difficult, endoscopic OTSC closure provides particular benefit. It is our belief that this is the first case report of endoscopically salvaging a leak from a failed open GCF repair.

    Insertional Achilles tendon injuries can be difficult to treat when minimal tendon tissue remains for anastomosis. Moreover, in the chronic case with tendon shortening, operative repair can be more difficult than acute rupture. It is particularly desirable to reinforce the tendons, in addition to performing primary repair, in patients with renal or systemic diseases because of the accelerated collagen degeneration. Many techniques have been described for the surgical management of Achilles tendon rupture; however, none has shown clear superiority. We report the case of a 50-year-old renal transplant patient with a spontaneous distal Achilles tendon injury that we repaired using the pull-out technique reinforced with an autologous semitendinosus graft. At 2 years postoperatively, the ankle-hindfoot scale score was 92 points, and the postoperative course was without complication. We believe that the free hamstring tendon autograft is advantageous for this repair, because it is easy to handle, has limited donor site morbidity, and preserves the structures around the ankle.

    2015-03-01

    Full Text Available Inguinal hernia is one of the most surgical common diseases in clinical practice. The history of inguinal hernia repair originated in the ancient times and the treatment has evolved, developed and changed since. [1] The most recent one is the concept of tension - free repair which remains popular among surgeons today. It is interesting to note, though, that numerous literatures have been published on this disease in the small anatomical space despite its simplicity. In the past couple of years, most publications focused on laparoscopic surgery and the different types of prosthetic mesh. Giant inguinal hernia, however, is more unusual and significantly challenging in terms of surgical management. It is defined as an ingu inal hernia that extends below the midpoint of inner thigh when the patient is in standing position. [2] No treatment has been adopted as standard procedure for this uncommon disease and several repair techniques are suggested by published articles and case reports. Further, the absence of large scale comparative study is expected to continue due to the relatively low number of cases. As a result, choosing a surgical procedure is made difficult and the decision must be made intraoperatively. A 55 - year - old ma le patient presented with Left Giant inguinal hernia and compromised quality of life due to pain and sexual discomfort. Lichtenstein’s polypropylene mesh repair was done after reducing the sac contents (omentum and ileum with partial omentectomy. There wa s no loss of intra - abdominal domain. Postoperative period was uneventful. In literature many techniques are available to increase the intra - abdominal cavity (a Creating progressive preoperative pneumoperitoneum (b Creation of ventral wall defect (c surg ical debulking of hernia contents.

    Full Text Available We describe an effective surgical technique in primary repair of the spinal dura during minimally invasive spine surgery (MISS. Objective. Minimally invasive spine surgery includes the treatment of intradural lesions, and proper closure of the dura is necessary. However, primary dural closure can be difficult due to the restricted space of MIS retractors and the availability of appropriate surgical instrumentation. Methods. We describe the use of a needle already used in the pediatric neurosurgical arena that can facilitate easier and safer closure of spinal dura through MISS retractors in two illustrative intradural cases. Results and Discussion. The primary dural closure technique is described and patient demographics are included. The instruments specifically used for the intradural closure through MIS retractor systems include (1 4-0 Surgilon braided nylon (Covidien, Dublin, Ireland with a CV-20 taper 1/2 circle, 10 mm diameter needle; (2 Scanlan (Saint Paul, MN, USA dura closure set. Conclusion. Successful primary dural repair can be performed on primary and incidental durotomies during minimally invasive spinal surgery. We describe the novel use of a 10 mm diameter needle to help surgeons safely and efficiently close the dura with more ease than previously described.

  6. Are valve repairs associated with better outcomes than replacements in patients with native active valve endocarditis?

    Zhao, Dong; Zhang, Benqing

    2014-12-01

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether valve replacement was associated with higher morbidity and mortality rates than valve repair in patients with native active valve endocarditis. Altogether 662 papers were found using the reported search, of which 7 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Traditionally, valve replacement has been the standard therapy for valve endocarditis when surgical treatment is indicated. But now valve repair is increasingly used as an alternative, which may avoid disadvantages of anticoagulation, lower the risk of prosthetic infection and improve postoperative survival. To compare outcomes of these two treatments between studies can be difficult because most of related papers contain raw data on prosthetic valve endocarditis or healed endocarditis, which were excluded from our manuscript. Studies only analysing the outcomes of either of these treatments without the comparison of valve repair and replacement were also excluded. Finally, seven papers were identified. The American Heart Association/American College of Cardiology 2006 valvular guidelines recommended that mitral valve repair should be performed instead of replacement when at all possible. In three of the seven studies, there were significant differences between valve repair and replacement in long-term survival. One study found that aortic valve repair offered better outcomes in freedom from reoperation at 5 years (P = 0.021) and in survival at 4 years (repair vs replacement 88 vs 65%; P = 0.047). One study reported that there was improved event-free survival at 10 years in the mitral valve repair group (P = 0.015), although there was more previous septic embolization in this group. In one study, early and late mortality

    Quadriceps tendon rupture is an incapacitating injury that usually requires surgical repair. Traditional repair methods involve transpatellar suture tunnels, but recent reports have introduced the idea of using suture anchors to repair the ruptured tendon. We present 5 cases of our technique of using suture anchors to repair the ruptured quadriceps tendon.

    Obesity may be the most predominant risk factor for recurrence following ventral hernia repair. This is secondary to significantly increased intra-abdominal pressures, higher rates of wound complications, and the technical difficulties encountered due to obesity. Medically managed weight loss prior to surgery is difficult. One potential strategy is to provide a surgical means to correct patient weight prior to hernia repair. After institutional review board approval, we reviewed the medical records of all patients who underwent gastric bypass surgery prior to the definitive repair of a complex ventral hernia at our medical center. Twenty-seven morbidly obese patients with an average of 3.7 (range 1-10) failed ventral hernia repairs underwent gastric bypass prior to definitive ventral hernia repair. Twenty-two of the gastric bypasses were open operations and five were laparoscopic. The patients' average pre-bypass body mass index (BMI) was 51 kg/m2 (range 39-69 kg/m2), which decreased to an average of 33 kg/m2 (range 25-37 kg/m2) at the time of hernia repair at a mean of 1.3 years (range 0.9-3.1 years) after gastric bypass. Seven patients had hernia repair at the same time as their gastric bypass (four sutured, three biologic mesh), all of which recurred. Of the 27 patients, 19 had an open hernia repair and eight had a laparoscopic repair. Panniculectomy was performed concurrently in 15 patients who had an open repair. Prior to formal hernia repair, one patient required an urgent operation to repair a hernia incarceration and a small-bowel obstruction 11 months after gastric bypass. The average hernia and mesh size was 203 cm2 (range 24-1,350 cm2) and 1,040 cm2 (range 400-2,700 cm2), respectively. There have been no recurrences at an average follow-up of 20 months (range 2 months-5 years). Gastric bypass prior to staged ventral hernia repair in morbidly obese patients with complex ventral hernias is a safe and definitive method to effect weight loss and facilitate a

    2007-02-01

    Information regarding the quality of autologous chondrocyte implantation repair is needed to determine whether the current autologous chondrocyte implantation surgical technology and the subsequent biologic repair processes are capable of reliably forming durable hyaline or hyaline-like cartilage in vivo. We report and analyze the properties and qualities of autologous chondrocyte implantation repairs. We evaluated 66 autologous chondrocyte implantation repairs in 57 patients, 55 of whom had histology, indentometry, and International Cartilage Repair Society repair scoring at reoperation for mechanical symptoms or pain. International Knee Documentation Committee scores were used to address clinical outcome. Maximum stiffness, normalized stiffness, and International Cartilage Repair Society repair scoring were higher for hyaline articular cartilage repairs compared with fibrocartilage, with no difference in clinical outcome. Reoperations revealed 32 macroscopically abnormal repairs (Group B) and 23 knees with normal-looking repairs in which symptoms leading to arthroscopy were accounted for by other joint disorders (Group A). In Group A, 65% of repairs were either hyaline or hyaline-like cartilage compared with 28% in Group B. Autologous chondrocyte repairs composed of fibrocartilage showed more morphologic abnormalities and became symptomatic earlier than hyaline or hyaline-like cartilage repairs. The hyaline articular cartilage repairs had biomechanical properties comparable to surrounding cartilage and superior to those associated with fibrocartilage repairs.

    Numerous bone and soft tissue grafting techniques are followed to repair cleft of lip and palate (CLP) defects. In addition to the gold standard surgical interventions involving the use of autogenous grafts, various allogenic and xenogenic graft materials are available for bone regeneration. In an attempt to discover minimally invasive and cost effective treatments for cleft repair, an exceptional growth in synthetic biomedical graft materials have occurred. This study gives an overview of the use of dental materials to repair cleft of lip and palate (CLP). The eligibility criteria for this review were case studies, clinical trials and retrospective studies on the use of various types of dental materials in surgical repair of cleft palate defects. Any data available on the surgical interventions to repair alveolar or palatal cleft, with natural or synthetic graft materials was included in this review. Those datasets with long term clinical follow-up results were referred to as particularly relevant. The results provide encouraging evidence in favor of dental and other related biomedical materials to fill the gaps in clefts of lip and palate. The review presents the various bones and soft tissue replacement strategies currently used, tested or explored for the repair of cleft defects. There was little available data on the use of synthetic materials in cleft repair which was a limitation of this study. In conclusion although clinical trials on the use of synthetic materials are currently underway the uses of autologous implants are the preferred treatment methods to date.

    Extensive ureteric lesions raise difficult problems of surgical repair. This is also the case for upper ureteric lesions that often require replacement of the damaged segment or even autologous transplantation. The authors report a case of iatrogenic ureteric lesion resulting in a large defect in a patient operated 6 months previously for an L4-L5 disk hernia, which was treated successfully by interposition of an appendicular graft between the two ureteric stumps. In the light of this case, the authors discuss the various appearances of iatrogenic ureteric lesions with particular emphasis on the value of appendicular ureteroplasty due to its simplicity and low morbidity, while waiting for progress in the field of biocompatible substitutes.

  14. Surgical ethics: surgical virtue and more.

    Science.gov (United States)

    Vercler, Christian J

    2015-01-01

    The encounter between a patient and her surgeon is unique for several reasons. The surgeon inflicts pain upon a patient for the patient's own good. An operative intervention is irreducibly personal, such that the decisions about and performance of operations are inseparable from the idiosyncrasies of the individual surgeon. Furthermore, there is a chasm of knowledge between the patient and surgeon that is difficult to cross. Hence, training in the discipline of surgery includes the inculcation of certain virtues and practices to safeguard against abuses of this relationship and to make sure that the best interests of the patient are prioritized. The stories in this issue are evidence that in contemporary practice this is not quite enough, as surgeons reflect on instances they felt were ethically challenging. Common themes include the difficulty in communicating surgical uncertainty, patient-surgeon relationships, ethical issues in surgical training, and the impact of the technological imperative on caring for dying patients.

    Background Surgical reconstructive planning following Mohs surgery can be a difficult subject for dermatology residents to master. Prior research demonstrates that active learning is preferred and more effective compared to passive learning models and that dermatology residents desire greater complexity and volume in surgical training. We present a novel, active, problem-based learning tool for the education of Mohs reconstruction with the goal of improving residents’ ability to plan surgical reconstructions. Materials and methods The Mohs Surgical Reconstruction Educational Activity is an active, problem-based learning activity in which residents designed repairs for planned Mohs defects prior to surgery on an iPad application or on a printed photograph. The attending Mohs surgeon reviewed the reconstructive designs, provided feedback, guided discussion, and facilitated insight into additional issues requiring further review. Residents performed or observed the Mohs and reconstructive surgical procedures for respective repairs. Surveys were administered to participants before and after participating in the Mohs Surgical Reconstruction Educational Activity to assess the educational value of the activity. Survey responses were recorded on a 5-point Likert scale. Results Mean participant-reported confidence in flap and graft knowledge, flap and graft planning, and flap and graft performance increased 1.50–2.50 Likert scale points upon completion of the Mohs surgery rotation by residents participating in the educational activity. The observed trend was larger in the dermatology resident subset, with increases of 2.00–3.50 Likert scale points reported for these questions. Mean participant-reported likelihoods of performing flaps and grafts in the future increased 0.25–0.50 Likert scale points among all residents participating in the educational activity and 0.50–1.00 Likert scale points in the dermatology resident subset.

    1993-01-01

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    2015-04-01

    Full Text Available Background: Historically all paraesophageal hernias were repaired surgically, today intervention is reserved for symptomatic paraesophageal hernias. In this review, we describe the indications for repair and explore the controversies in paraesophageal hernia repair, which include a comparison of open to laparoscopic paraesophageal hernia repair, the necessity of complete sac excision, the routine performance of fundoplication, and the use of mesh for hernia repair.Methods: We searched Pubmed for papers published between 1980 and 2015 using the following keywords: hiatal hernias, paraesophageal hernias, regurgitation, dysphagia, gastroesophageal reflux disease, aspiration, GERD, endoscopy, manometry, pH monitoring, proton pump inhibitors, anemia, iron deficiency anemia, Nissen fundoplication, sac excision, mesh, mesh repair. Results: Indications for paraesophageal hernia repair have changed, and currently symptomatic paraesophageal hernias are recommended for repair. In addition, it is important not to overlook iron-deficiency anemia and pulmonary complaints, which tend to improve with repair. Current practice favors a laparoscopic approach, complete sac excision, primary crural repair with or without use of mesh, and a routine fundoplication.

    A turbine repair process, a repaired coating, and a repaired turbine component are disclosed. The turbine repair process includes providing a turbine component having a higher-pressure region and a lower-pressure region, introducing particles into the higher-pressure region, and at least partially repairing an opening between the higher-pressure region and the lower-pressure region with at least one of the particles to form a repaired turbine component. The repaired coating includes a silicon material, a ceramic matrix composite material, and a repaired region having the silicon material deposited on and surrounded by the ceramic matrix composite material. The repaired turbine component a ceramic matrix composite layer and a repaired region having silicon material deposited on and surrounded by the ceramic matrix composite material.

    The repair of umbilical and epigastric hernias still represents a challenge to surgeons. Although a common and relatively simple procedure, there is no exact protocol today on how the repair should be done. The Mayo technique and its alterations could not stand the test of time: a recurrence rate of 20% and higher is not acceptable for any surgical procedure. Although there is no consensus opinion, one thing is clear: the importance of an anatomic repair without tension and without an artificial enlargement of the defect. In 1987 Lichtenstein reported on 6321 cases of herniorraphy with a tension free repair, and in 1994 Stuart reemphasized that special importance in his editorial in the Lancet. A newer study from Brancato and coworkers in Italy also states the advantage of a tension-free prosthetic repair in 16 patients with epigastric hernia. We have gone even further and recommend a tailored-to-the-patient repair using a customized polypropylene mesh and a one-layer running suture. The advantages should be obvious: no artificial creation of an even bigger than original defect, a completely tension-free repair, and little to no recurrence of the hernia. Our results clearly prove that assumption. Moreover, the procedure is extremely safe and complications are very rare and minor. We conclude that using a mesh plug in a customized tension-free repair of umbilical and epigastric hernia shows many advantages over the commonly used methods. And we finally conclude with the words of Albert Einstein: "The only source of knowledge is experience."

    Groin hernias are very common, and surgical treatment is usually recommended. In fact, hernia repair is the most common surgical procedure performed worldwide. In countries such as the USA, China, and India, there may easily be over 1 million repairs every year. The need for this surgery has become an important socioeconomic problem and may affect health-care providers, especially in aging societies. Surgical repair using mesh is recommended and widely employed in Western countries, but in many developing countries, tissue-to-tissue repair is still the preferred surgical procedure due to economic constraints. For these reason, the development and implementation of guidelines, consensus, or recommendations may aim to clarify issues related to best practices in inguinal hernia repair in Asia. A group of Asian experts in hernia repair gathered together to debate inguinal hernia treatments in Asia in an attempt to reach some consensus or develop recommendations on best practices in the region. The need for recommendations or guidelines was unanimously confirmed to help overcome the discrepancy in clinical practice between countries; the experts decided to focus mainly on the technical aspects of open repair, which is the most common surgery for hernia in our region. After the identification of 12 main topics for discussion (indication, age, and sex; symptomatic and asymptomatic hernia: type of hernia; type of treatment; hospital admission; preoperative care; anesthesia; surgical technique; perioperative care; postoperative care; early complications; and long-term complications), a search of the literature was carried out according to the five levels of the Oxford Classification of Evidence and the four grades of recommendation.

  8. Transvesicoscopic Repair of Vesicovaginal Fistula

    2010-01-01

    Full Text Available Introduction. Vesicovaginal fistula has been a social and surgical problem for centuries. Many surgical techniques have been developed to correct this abnormality, including transabdominal, transvaginal, and endoscopic approaches. The best approach is probably the one with which the surgeon feels most experienced and comfortable. Laparoscopy has become increasingly popular in urology, reducing the invasiveness of treatment and shortening the period of convalescence. We report our results of transvesicoscopic approach for VVF repair. Materials and Methods. Patients with VVF were offered repair using the transvesicoscopic route. With the patient under general anaesthesia and in modified lithotomy position cystoscopy was performed with gas insufflation. Under cystoscopic guidance the bladder was fixed to anterior abdominal wall and ports inserted into the bladder. The fistula was repaired under endoscopic vision. Results. Four women, who had VVF following abdominal hysterectomy, underwent this procedure. The operating time ranged from 175 to 235 minutes. There was minimal bleeding. Post operative complications included ileus in one and fever in another. No recurrence of VVF was noted in any patient. Conclusions. Transvesicoscopic repair of VVF is feasible, safe, and results in lower morbidity and quicker recovery time.

    2006-04-01

    Complete rupture of the quadriceps tendon is a well-described injury. There is a scarcity of literature relating to the outcome of patients with this injury after surgery. We undertook a retrospective analysis of patients who had surgical repair of their quadriceps tendon at our institution over a 13-year period, totalling 21 patients. Males were more commonly affected, with a male/female ratio of 4:1. The peak incidence was in the sixth decade of life. Assessment consisted of the completion of a functional knee questionnaire and a clinical examination. Symptomatic outcome following surgical repair was good with a mean symptom score generated of 19.16 out of a maximum of 25 using the Rougraff et al scoring system. Most of the patients returned to their pre-injury level of activity. Five degrees deficit and extension lag was present in three patients; these patients had the quadriceps repaired using transosseous sutures. Patients who had direct repair of the tendon using the Bunnell technique had lower Rougraff scores than the rest.

  10. Cortical Button Fixation: A Better Patellar Tendon Repair?

    Patellar tendon ruptures require surgical repair to optimize outcomes, but no consensus exists regarding the ideal repair technique. Cortical button fixation is a secure method for tendon repair that has not been studied in patellar tendons. Cortical button repair is biomechanically superior to the standard transpatellar repair and biomechanically equivalent to suture anchor repair. Controlled laboratory study. Twenty-three fresh-frozen cadaveric knees were used to compare 3 techniques of patellar tendon repair after a simulated rupture at the inferior pole of the patella. Repairs were performed at 45° of flexion using a standard transpatellar suture repair (n = 7), polyetheretherketone (PEEK) suture anchor repair (n = 8), or cortical button repair (n = 8). All specimens were tested on a custom apparatus to simulate cyclic open kinetic chain quadriceps contraction from extension to 90(o) of flexion. Outcomes of gap formation up to 250 cycles, maximum load to failure, and mode of failure were evaluated. Cortical button repair had significantly less gap formation than anchor repair after 1 cycle (P button repair sustained significantly higher loads to failure than anchor repair and suture repair (P button repairs either failed through the suture (n = 5), secondary failure of the patellar tendon (n = 2), or subsidence of the button through the anterior cortex of the patella (n = 1). Patellar tendon repair using cortical button fixation demonstrated mechanical advantages over suture repair and anchor repair in cadaveric specimens. Cortical button fixation showed less cyclic gap formation and withstood at least twice the load to failure of the construct. The biomechanical superiority of cortical button fixation may impart clinical advantages in accelerating postoperative rehabilitation. © 2016 The Author(s).

    Quadriceps tendon rupture is an uncommon injury. This disabling condition is the result of direct or indirect trauma. It requires surgical repair to avoid poor outcomes in cases of neglected or chronic rupture. In most acute cases, simple tendon suture or reinsertion is suitable for an extensor mechanism reconstruction of the knee joint. However, chronic lesions often require a tendon graft or flap reconstruction. We report a case of a 15-year-old male who was diagnosed with a chronic quadriceps rupture with a patellar superior pole fracture. We performed quadriceps reconstruction using tibialis anterior allograft tendon and additional screw fixation to reconstruct the extensor mechanism and recover knee joint range of motion to prevent a high-level functional restriction. The treatment was difficult and limited due to neglect for 9-months that led to ankylosis accompanied with nonunion of tibial fracture. Our surgical treatment using allograft tendon resulted in a very good outcome after 30 months of follow-up.

    2013-10-01

    Umbilical and epigastric hernias are primary midline defects that are present in up to 50% of the population. In the United States, only about 1% of the population carries this specific diagnosis, and only about 11% of these are repaired. Repair is aimed at symptoms relief or prevention, and the patient's goals and expectations should be explicitly identified and aligned with the health care team. This article details some relevant and interesting anatomic issues, reviews existing data, and highlights some common and important surgical techniques. Emphasis is placed on a patient-centered approach to the repair of umbilical and epigastric hernias.

    2004-10-01

    Full Text Available Many skilled eye surgeons in remote hospitals face the frustration that a simple instrument, once in good working order, is now bent or broken. Many eye units have a box containing instruments needing repair, hidden away in a stock room cupboard, in the hope that someone, someday, will be able to redeem them. This article gives guidelines on: 1 How to assess instruments and identify those that can be repaired locally, those that should be sent to a professional repair service and those that cannot be repaired at all. 2 How to make adjustments and carry out basic maintenance and repairs of surgical instruments. The article will refer primarily to instruments in an extracapsular cataract extraction set.

    2013-01-01

    PURPOSE: Inguinal hernia repair is a common surgical procedure, and the majority of operations worldwide are performed ad modum Lichtenstein (open tension-free mesh repair). Until now, no suitable surgical training model has been available for this procedure. We propose an experimental surgical...... training model for Lichtenstein's procedure on the male and female pig. METHODS: In the pig, an incision is made 1 cm cranially to the inguinal sulcus where a string of subcutaneous lymph nodes is located and extends toward the pubic tubercle. The spermatic cord is located in a narrow sulcus in the pig...... pigs, and a total of 55 surgeons have been educated to perform Lichtenstein's hernia repair in these animals. CONCLUSIONS: This new experimental surgical model for training Lichtenstein's hernia repair mimics the human inguinal anatomy enough to make it suitable as a training model. The operation...

  16. Dorsal variant blister aneurysm repair.

    Couldwell, William T; Chamoun, Roukoz

    2012-01-01

    Dorsal variant proximal carotid blister aneurysms are treacherous lesions to manage. It is important to recognize this variant on preoperative angiographic imaging, in anticipation of surgical strategies for their treatment. Strategies include trapping the involved segment and revascularization if necessary. Other options include repair of the aneurysm rupture site directly. Given that these are not true berry aneurysms, repair of the rupture site involves wrapping or clip-grafting techniques. The case presented here was a young woman with a subarachnoid hemorrhage from a ruptured dorsal variant blister aneurysm. The technique used is demonstrated in the video and is a modified clip-wrap technique using woven polyester graft material. The patient was given aspirin preoperatively as preparation for the clip-wrap technique. It is the authors' current protocol to attempt a direct repair with clip-wrapping and leaving artery sacrifice with or without bypass as a salvage therapy if direct repair is not possible. Assessment of vessel patency after repair is performed by intraoperative Doppler and indocyanine green angiography. Intraoperative somatosensory and motor evoked potential monitoring is performed in all cases. The video can be found here: http://youtu.be/crUreWGQdGo.

    Aortic coarctation can be repaired surgically or percutaneously. The decision should be made according to the anatomy and location of the coarctation, age of the patient, presence of other cardiac lesions, and other anatomic determinants (extensive collaterals or aortic calcification). This article reviews the different therapeutic options available, explaining the differences between children and adults, describing different approaches to the same disease, exemplified by three cases of nonclassic surgical approach and one percutaneous treatment.

    Long, Aidan A; Fanta, Christopher H

    2012-01-01

    A minority of asthma patients have disease that proves difficult to control with usual medications and experience ongoing symptoms, poor quality of life, and limitations in activity and/or frequent asthma exacerbations. This group of patients accounts for much of the expense associated with asthma care and is the focus of national and international collaborative study groups. Distinguishing between "difficult-to-manage asthma" and truly "therapy-resistant asthma" is helpful and promotes a systematic consideration of contributory factors. Critical evaluation of factors contributing to difficult-to-manage asthma including adverse environment, comorbidities, nonadherence, and incorrect diagnosis is recommended in a systematic fashion in Part 1 of this contribution.

    A caecal appendix within an inguinal hernia, with or without appendicitis, is defined as Amyand's hernia. In 1% of inguinal hernias an appendix without inflammation can be found, however, the prevalence of appendicitis in a hernia sac is only 0.08-0.13%. Male of 43 years old, began two days before admission with pain in the right inguinal region. He was scheduled for surgery due to a complication of a right inguinal hernia. The surgical findings were Amyand's hernia, necrotic spermatic cord, and perforated appendix. Surgical repair was performed with a favourable outcome, and he was discharged on the fourth postoperative day. Most of Amyand's hernia exhibit characteristics of incarcerated or strangulated inguinal hernia. Even acute appendicitis or perforated appendix within the hernia sac does not reflect specific symptoms or signs, therefore, a preoperative clinical diagnosis of Amyand's hernia is difficult to achieve. In our case, the patient had perforated appendicitis, developing necrosis of the spermatic cord. Orchiectomy, appendectomy, and inguinal hernia repair was performed without placing mesh. Due to the controversy on the use of mesh in contaminated abdominal wall defects, it was not indicated here, due to the high risk of wound infection and appendicular fistula. An extremely rare condition is presented, with a surgical choice that led to a favourable outcome. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A.

    Full Text Available Brett Williams,1 Christine King,1 Tanya Edlington,21Department of Community Emergency Health and Paramedic Practice, Monash University, Franskton, VIC, 2The Conversation Clinic Pty Ltd, Melbourne, VIC, Australia Background: Clinical supervisors are responsible for managing many facets of clinical learning and face a range of challenges when the need for "difficult" conversations arises, including the need to manage conflict and relationships. Methods: Spotlight on Conversations Workshop was developed to improve the capacity of clinical supervisors to engage in difficult conversations. They were designed to challenge the mindset of clinical supervisors about difficult conversations with students, the consequences of avoiding difficult conversations, and to offer activities for practicing difficult conversations. Preworkshop, postworkshop, and 4-month follow-up evaluations assessed improvements in knowledge, intent to improve, and confidence along with workshop satisfaction. Results: Nine workshops were delivered in a range of locations across Victoria, Australia, involving a total of 117 clinical supervisors. Preworkshop evaluations illustrated that more than half of the participants had avoided up to two difficult conversations in the last month in their workplace. Postworkshop evaluation at 4 months showed very high levels of satisfaction with the workshop's relevancy, content, and training, as well as participants' intention to apply knowledge and skills. Also shown were significant changes in participants' confidence to have difficult conversations not only with students but also with other peers and colleagues. In follow-up in-depth interviews with 20 of the 117 participants, 75% said they had made definite changes in their practice because of what they learned in the workshop and another 10% said they would make changes to their practice, but had not had the opportunity yet to do so. Conclusion: We conclude that the Spotlight on

    2015-06-01

    Full Text Available When we mention about surgical treatment of any tumor residing on the skin independent of its benign or malignant nature, the first method we recall is excision. Elliptical excision is the mainstay of the dermatologic surgery. Each excision ends with a defect for which we are responsible to repair functionally and cosmetically. The diameter of the tumor we excised and the safety margin used for excision determine the diameter of the final defect. After achieving tumor free lateral and deep margins with the appropriate surgical method, we decide between the repair options of second intention healing, primary repair, flaps, full or split thickness grafts, considering the diameter and the anatomic localization of the defect, for the best functional and cosmetic result for that specific defect. This review overviews not only the most common dermatologic surgical methods, but also Mohs surgery which is a method rarely used in our country, although it is the treatment of choice for the treatment of high risk basal cell carcinoma (BCC and squamous cell carcinoma (SCC.

  4. Current Trends in the Management of Difficult Urinary Catheterizations

    Directory of Open Access Journals (Sweden)

    Paul A Willette

    2012-12-01

    Full Text Available Routine urinary catheter placement may cause trauma and poses a risk of infection. Male catheterization, in particular, can be difficult, especially in patients with enlarged prostate glands or other potentially obstructive conditions in the lower urinary tract. Solutions to problematic urinary catheterization are not well known and when difficult catheterization occurs, the risk of failed catheterization and concomitant complications increase. Repeated and unsuccessful attempts at urinary catheterization induce stress and pain for the patient, injury to the urethra, potential urethral stricture requiring surgical reconstruction, and problematic subsequent catheterization. Improper insertion of catheters also can significantly increase healthcare costs due to added days of hospitalization, increased interventions, and increased complexity of follow-up evaluations. Improved techniques for catheter placement are essential for all healthcare personnel involved in the management of the patient with acute urinary retention, including attending emergency physicians who often are the first physicians to encounter such patients. Best practice methods for blind catheter placement are summarized in this review. In addition, for progressive clinical practice, an algorithm for the management of difficult urinary catheterizations that incorporates technology enabling direct visualization of the urethra during catheter insertion is presented. This algorithm will aid healthcare personnel in decision making and has the potential to improve quality of care of patients.

  5. The UCLA surgical approach to sphincteric incontinence in women.

    Rovner, E S; Ginsberg, D A; Raz, S

    1997-01-01

    Stress urinary incontinence (SUI) in the female may be treated by a variety of non-surgical and surgical therapies. However, once the patient has chosen to undergo operative repair the ideal procedure is based on three considerations: the degree of anterior vaginal wall prolapse, the degree of incontinence and associated anatomic abnormalities requiring surgical repair. In the vast majority of cases vaginal wall sling is our procedure of choice for the surgical treatment of SUI in the female. Vaginal wall sling is based on sound anatomic principles, may be performed as an outpatient procedure and is equally efficacious for the treatment of SUI due to anatomic incontinence (urethral hypermobility) and intrinsic sphincter deficiency. Since vaginal wall sling is performed through a transvaginal approach, other associated manifestations of pelvic floor prolapse such as rectocele can be addressed and repaired simultaneously. When necessary the vaginal wall sling can be easily modified to repair large grade cystoceles.

    Surgical treatment for traumatic shoulder instability has progressed in tandem with the evolution of the current understanding of the anatomy and biomechanics of the shoulder. Proponents of incorporating the middle glenohumeral ligament (MGHL) in Bankart repair believe this technique could increase repair strength. The purpose of this biomechanical study was to compare the range of motion and humeral head kinematic changes that result from including the MGHL in a Bankart repair in an effort to identify possible changes in shoulder biomechanics as a result of this addition in surgical repair.Six cadaveric shoulders were tested in 4 conditions: intact, Bankart lesion, repair excluding the MGHL, and repair including the MGHL. Each condition was tested for range of motion, glenohumeral translation, and humeral head apex position. Standard Bankart repair and repair with MGHL inclusion resulted in decreased range of motion, but no statistically significant difference was found between the 2 repair types (P=.846). Anterior translation was significantly reduced with both the Bankart repair (4.8 ± .9; P=.049) and included MGHL repair (4.6 ± 0.9; P=.029). No statistically significant difference was found between both repairs (P=.993). Although both repairs showed posterior displacement of the humeral head apex when in external rotation, this trend only reached statistical significance when compared with the Bankart lesion in 90° of external rotation (P=.0456); however, no significant difference was found between the 2 repairs (P=.999). Inclusion or exclusion of the MGHL in a Bankart repair does not significantly affect the range of motion, translation, or kinematics of the glenohumeral joint. Copyright 2013, SLACK Incorporated.

    Rotator cuff tears are often surgically repaired, generally with good results. However, repairs not infrequently retear, and how important repair integrity is with respect to early functional outcomes after rotator cuff repair is unclear. Thus, the purpose of this study was to determine the effect of a retear on overhead activities in a large cohort of patients after rotator cuff repair. This was a retrospective cohort study of prospectively collected data from 1600 consecutive rotator cuff repairs. Outcomes were based on patient responses to the L'Insalata Shoulder Questionnaire and findings on examination preoperatively and at 6 months of follow-up. Repair integrity was determined by ultrasound imaging at the 6-month follow-up visit. The 1600 patients (885 men, 715 women) were a mean age of 58 years. Postoperative ultrasound imaging found 13% (211 of 1600) of repairs had retorn. Significant improvements were seen irrespective of rotator cuff integrity in pain levels with overhead activity (P rotation strength (P rotator cuff repair integrity on shoulder function. Patients who had an arthroscopic rotator cuff repair reported significant improvements in overhead pain levels irrespective of the repair integrity at 6 months. Repair integrity influenced supraspinatus and external rotation power, where patients with intact repairs were stronger than those with a retear.

    Jakob Burcharth

    Full Text Available INTRODUCTION: Groin hernia repair is a commonly performed surgical procedure in the western world but large-scaled epidemiologic data are sparse. Large-scale data on the occurrence of groin hernia repair may provide further understanding to the pathophysiology of groin hernia development. This study was undertaken to investigate the age and gender dependent prevalence of groin hernia repair. METHODS: In a nationwide register-based study, using data from the Civil Registration System covering all Danish citizens, we established a population-based cohort of all people living in Denmark on December 31(st, 2010. Within this population all groin hernia repairs during the past 5 years were identified using data from the ICD 10(th edition in the Danish National Hospital Register. RESULTS: The study population covered n = 5,639,885 persons. During the five years study period 46,717 groin hernia repairs were performed (88.6% males, 11.4% females. Inguinal hernias comprised 97% of groin hernia repairs (90.2% males, 9.8% females and femoral hernias 3% of groin hernia repairs (29.8% males, 70.2% females. Patients between 0-5 years and 75-80 years constituted the two dominant groups for inguinal hernia repair. In contrast, the age-specific prevalence of femoral hernia repair increased steadily throughout life peaking at age 80-90 years in both men and women. CONCLUSION: The age distribution of inguinal hernia repair is bimodal peaking at early childhood and old age, whereas the prevalence of femoral hernia repair increased steadily throughout life. This information can be used to formulate new hypotheses regarding disease etiology with regard to age and gender specifications.

    Diagnosis and management of severe asthma implies the definition of different entities, that is, difficult asthma and refractory severe asthma, but also the different phenotypes included in the term refractory severe asthma. A complete evaluation by a physician expert in asthma is necessary, adapted for each child. Identification of mechanisms involved in different phenotypes in refractory severe asthma may improve the therapeutic approach. The quality of care and monitoring of children with severe asthma is as important as the prescription drug, and is also crucial for differentiating between severe asthma and difficult asthma, whereby expertise is required.

    2009-03-01

    The management of facial paralysis is one of the most complex areas of reconstructive surgery. Given the wide variety of functional and cosmetic deficits in the facial paralysis patient, the reconstructive surgeon requires a thorough understanding of the surgical techniques available to treat this condition. This review article will focus on surgical management of facial paralysis and the treatment options available for acute facial paralysis (facial paralysis (3 weeks to 2 yr) and chronic facial paralysis (>2 yr). For acute facial paralysis, the main surgical therapies are facial nerve decompression and facial nerve repair. For facial paralysis of intermediate duration, nerve transfer procedures are appropriate. For chronic facial paralysis, treatment typically requires regional or free muscle transfer. Static techniques of facial reanimation can be used for acute, intermediate, or chronic facial paralysis as these techniques are often important adjuncts to the overall management strategy.

    Endovascular aneurysm repair has considerable potential advantages over the surgical approach as a treatment for thoracic aortic rupture, in part because open surgical repair of ruptured thoracic aortic aneurysms is associated with high mortality and morbidity rates. We describe the successful endovascular deployment of stent-grafts to repair a contained rupture of a descending thoracic aortic aneurysm in an 86-year-old man whose comorbidities prohibited surgery. Two months after the procedure, magnetic resonance angiography showed a patent stent-graft, a patent left subclavian artery, and complete exclusion of the aneurysm. PMID:16878637

    It's shown by literature and confirmed by Author's experience that, on account of the excellent results, prosthetic repair of inguinal hernia is more effective than "conventional" (Bassini, Mc Vay, Shouldice). Between January 1993 and December 2000 were observed 875 patients with inguinal hernia (814 monolateral, 61 bilateral); all patients underwent a Lichtenstein repair both in the primary version and in its variations (internal ring plastic, trasversalis plicate, plug repair). The patients were discharged from hospital within 24 hours after surgery in 90% of cases. No important intraoperative complications were observed; the patients restarting work varied from 3 to 15 days after the discharging in relation to patient anxiety, onset of complications and to the type of work. The complications observed were: urine retention (1.6%), superficial haematoma (1.3%), superficial infection (1%), wound suppuration (0.5%), serous effusion (0.7%), postsurgery pain (2.1%), scrotal edema (1.7%), persistent inguinal neuralgia (0.6), local hypoesthesia (4.3%), ischemical orchitis (0.1%), recurrence (0.2%). In conclusion Authors assert that "tension free" repair allows optimal results both for the surgery point (easiness of the technique, repeatability, less invasivity, scanty incident of recurrences, low frequency of postoperative complications) and in economic terms, allowing an early mobilization of the patients. A further improvement would be obtained with more care in surgical and patient management, with more excellent results.

    2005-06-01

    Full Text Available Abstract Background Tracheal malignancies are usual victim of delay in diagnosis by virtue of their symptoms resembling asthma. Sometimes delayed diagnosis may lead to almost total airway obstruction. For difficult airways, not leaving any possibility of manipulation into neck region or endoscopic intervention, femorofemoral cardiopulmonary bypass can be a promising approach. Case Presentation We are presenting a case of tracheal adenoid cystic carcinoma (cylindroma occupying about 90% of the tracheal lumen. It was successfully managed by surgical excision of mass by sternotomy and tracheotomy under femorofemoral cardiopulmonary bypass (CPB. Conclusion Any patient with recurrent respiratory symptoms should be evaluated by radiological and endoscopic means earlier to avoid delay in diagnosis of such conditions. Femorofemoral cardiopulmonary bypass is a relatively safe way of managing certain airway obstructions.

    Full Text Available For some patients with impotence and concomitant severe tunical/corporeal tissue fibrosis, insertion of a penile prosthesis is the only option to restore erectile function. Closing the tunica over an inflatable penile prosthesis in these patients can be challenging. We review our previous study which included 15 patients with severe corporeal or tunical fibrosis who underwent corporeal reconstruction with autologous rectus fascia to allow placement of an inflatable penile prosthesis. At a mean follow-up of 18 months (range 12 to 64, all patients had a prosthesis that was functioning properly without evidence of separation, herniation, or erosion of the graft. Sexual activity resumed at a mean time of 9 weeks (range 8 to 10. There were no adverse events related to the graft or its harvest. Use of rectus fascia graft for coverage of a tunical defect during a difficult penile prosthesis placement is surgically feasible, safe, and efficacious.

    Ethically difficult situations are frequently encountered by healthcare professionals. Moral case deliberation is one form of clinical ethics support, which has the goal to support staff to manage ethical difficulties. However, little is known which difficult situations healthcare teams need to discuss. To explore which kinds of ethically difficult situations interprofessional healthcare teams raise during moral case deliberation. A series of 70 moral case deliberation sessions were audio-recorded in 10 Swedish workplaces. A descriptive, qualitative approach was applied, using thematic content analysis. Ethical considerations: An advisory statement specifying no objections to the study was provided from an Ethical Review Board, and consent to be recorded was assumed by virtue of participation in the moral case deliberation. Three themes emerged: powerlessness over managing difficult interactions with patients and next-of-kin, unease over unsafe and unequal care, and uncertainty over who should have power over care decisions. The powerlessness comprised feelings of insufficiency, difficulties to respond or manage patient's/next-of-kin's emotional needs or emotional outbursts and discouragement over motivating patients not taking responsibility for themselves. They could be uncertain over the patient's autonomy, who should have power over life and death, disclosing the truth or how much power next-of-kin should have. The findings suggest that the nature of the ethically difficult situations brought to moral case deliberations contained more relational-oriented ethics than principle-based ethics, were permeated by emotions and the uncertainties were pervaded by power aspects between stakeholders. MCD can be useful in understanding the connection between ethical issues and emotions from a team perspective.

    Gallstone ileus (GSI) is a rare cause of mechanical small bowel obstruction. It occurs when a fistula between the gallbladder and the small bowel facilitates the migration of gallstone(s) into the small bowel. The commonest site of impaction is in the terminal ileum. We report the case of a 71-year-old female presenting with GSI diagnosed on CT scan. She was surgically explored and gallstones extracted by a simple enterotomy leading to full recovery of the patient.

    2000-01-01

    Management of inflammatory bowel disease includes not only drug, endoscopic and surgical therapy but alsopsychosocial support, dietary and specific nutritional measures: a multidisciplinary medical, surgical, nursingand dietetic approach is essential for all patients, particularly those with complex or refractory disease. Inthis paper, current treatment of acute severe ulcerative colitis and steroid-refractory or -dependent Crohn'sdisease is reviewed. Adjunctive intravenous cyclosporin is an alternative to urgent colectomy in steroid-refractory patients with acute severe ulcerative colitis, while the place of intravenous heparin for thisindication awaits clarification. Azathioprine or 6-mercaptopurine are useful options in chronically active,steroid-refractory or -dependent Crohn's disease, but may take up to 4 months to work. Methotrexate is amore recent immunomodulatory alternative. Of new therapies selectively aimed at specific pathophysiologicaltargets, the first to reach clinical application is anti-TNF-alpha antibody (infliximab) for refractory Crohn'sdisease: its benefits are promising, but experience with it is limited to date, its cost is high and there areuncertainties about long-term safety. In view of the increasing variety and complexity of management optionsin inflammatory bowel disease, whether apparently responsive or difficult to treat, patients must participatein decisions about which therapies they are to be given.

    Resection of carotid body tumors can be difficult to perform because of its site, vascularity, arterial adherence and local cranial nerve involvement. Advances in vascular surgical technique have reduced the risks of perioperative complications such as carotid injury, stroke and death. From January 1980 to May 1994 20 patients (22 carotid body tumors) were examined. All patients except one were evaluated with a preoperative angiography. No preoperative embolization was performed. Thirteen patients underwent ultrasonography, nine a CT scan of the neck, 5 magnetic resonance scanning and two magnetic resonance angiography. One old patient refused operation. The authors report their experience on 21 carotid body tumor resections (14 Shamblin group I and 7 group II paragangliomas). Surgical technique is based on subadventitial resection (18 excisions) and 3 resections were performed from the medial surface of the carotid bifurcation which had been partially absorbed into the mass. In the last 15 operations intraoperative Somatosensorial Evoked Potential (SEP) monitoring has been used. Only two patient required arterial repair because intimal dissection and another patient needed vagus nerve section. The ligation of external carotid artery and internal carotid resection with graft replacement were never necessary in these patients. No early or late deaths occurred and no recurrences were detected at follow-up.

  8. Complication following primary repair of a penetrating bull horn injury to the trachea

    Full Text Available A 22-year-old male patient was admitted to the casualty with a bull horn injury in the lower zone of the neck in the midline. The patient was conscious and distressed but hemodynamically stable. Local examination revealed a lacerated wound. He underwent emergency primary repair of the wound under halothane anesthesia; intubation was done keeping in readiness all preparations for difficult airway management. Postoperatively, elective controlled ventilation was performed with continuous infusion of muscle relaxant. After approximately 8 hours of controlled ventilation, the syringe pump failed; this initially went unnoticed and made the patient cough and buck on the tube. Infusion was restarted after a bolus dose of vecuronium bromide intravenously but, meanwhile, the patient developed subcutaneous emphysema in the neck. He was immediately transferred to the operating room, where exploration of the surgical site revealed dehiscence of the tracheal wound; this had led to the subcutaneous emphysema. Repair of the tracheal wound dehiscence was not possible due to both lack of space and lack of tissue for apposition. Hence, a tracheostomy tube was inserted through the tracheal wound and the patient was transferred to the intensive care unit for elective controlled ventilation. The patient was weaned off the ventilator within 24 h and transferred to the surgical ward on spontaneous ventilation with the tracheostomy tube in situ. The size of the patient′s tracheostomy tube was reduced gradually by the serial exchange method. The wound ultimately healed with minimal scarring.

    This study aimed to determine the accuracy of commonly used preoperative difficult airway indices as predictors of difficult mask ventilation (DMV) in obese patients (BMI >30 kg/m2). In 309 consecutive obese patients undergoing general surgery, the modified Mallampati test, patient's Height/Thyromental distance ratio, Inter-Incisor Distance, Protruding Mandible (PM), history of Obstructive Sleep Apnea and Neck Circumference (NC) were recorded preoperatively. DMV was defined as Grade 3 mask ventilation (MV) by the Han's scale (MV inadequate, unstable or requiring two practitioners). Data are shown as means±SD or number and proportions. Independent DMV predictors were identified by multivariate analysis. The discriminating capacity of the model (ROC curve area) and adjusted weights for the risk factors (odds ratios) were also determined. BMI averaged 42.5±8.3 kg/m2. DMV was reported in 27 out of 309 patients (8.8%; 95%CI 5.6-11.9%). The multivariate analysis retained NC (OR 1.17; P2 associated factors as the best discriminating point for DMV. Obese patients show increased incidence of DMV with respect to the undifferentiated surgical population. Limited PM, Mallampati test and NC are important DMV predictors.

    Introduction Population screening for abdominal aortic aneurysms (AAA) halves the associated mortality and has led to the establishment of national screening programmes. Prediction of aneurysm growth and rupture is challenging and currently relies on serial diameter measurements with ultrasound. Recently, a novel MRI-based technique using ultrasmall superparamagnetic particles of iron oxide (USPIO) has demonstrated considerable promise as a method of identifying aneurysm inflammation and expansion. Methods and analysis The MA3RS study is a prospective observational multicentre cohort study of 350 patients with AAA in three centres across Scotland. All participants will undergo MRI with USPIO and aneurysm expansion will be measured over 2 years with CT in addition to standard clinical ultrasound surveillance. The relationship between mural USPIO uptake and subsequent clinical outcomes, including expansion, rupture and repair, will be evaluated and used to determine whether the technique augments standard risk prediction markers. To ensure adequate sensitivity to answer the primary question, we need to observe 130 events (composite of rupture or repair) with an estimated event rate of 41% over 2 years of follow-up. The MA3RS study is currently recruiting and expects to report in 2017. Discussion This is the first study to evaluate the use of USPIO-enhanced MRI to provide additional information to aid risk prediction models in patients with AAA. If successful, this study will lay the foundation for a large randomised controlled trial targeted at applying this technique to determine clinical management.

    Congenital mitral valve (MV) dysplasia is a relatively rare and highly complex cardiac disease. We present our results and illustrate the techniques used to repair these valves. Between 1972 and 2014, 100 consecutive patients underwent surgical repair of congenital MV dysplasia at our institution. Predominant MV regurgitation was present in 53 patients (53%) whereas mitral stenosis was prevalent in 47 (47%). There were five early (5%) and eight late deaths (9%). Actuarial survival was 95%, 94%, and 93% at 5, 10, and 20 years, respectively. Sixteen patients (18%) required reintervention due to subsequent MV dysfunction. Actuarial freedom from reintervention for MV dysfunction was 95%, 92%, and 89% at 5, 10, and 20 years, respectively. The mechanism underlying the valve dysfunction in congenital mitral valve dysplasia is multifactorial and requires the application of a variety of surgical techniques for repair. doi: 10.1111/jocs.12743 (J Card Surg 2016;31:352-356). © 2016 Wiley Periodicals, Inc.

    Full Text Available Recently, although some studies of open repair of the tendon of the quadriceps femoris have been published, there have been no reports in the literature on primary arthroscopic repair. In our present study, we present two cases of quadriceps tendon injury arthroscopically repaired with excellent results. Case 1 involved a 68-year-old man who was injured while shifting his weight to prevent a fall. MRI showed complete rupture at the insertion of the patella of the quadriceps tendon. The rupture was arthroscopically repaired using both suture anchor and pull-out suture fixation methods via bone tunnels (hereafter, pull-out fixation. Two years after surgery, retearing was not observed on MRI and both Japan Orthopedic Association (JOA Knee and Lysholm scores had recovered to 100. Case 2 involved a 50-year-old man who was also injured when shifting his weight to prevent a fall. MRI showed incomplete superficial rupture at the insertion of the patella of the quadriceps tendon. The rupture was arthroscopically repaired using pull-out fixation of six strand sutures. One year after surgery, MRI revealed a healed tendon and his JOA and Lysholm scores were 95 and 100, respectively. Thus, arthroscopic repair may be a useful surgical method for repairing quadriceps tendon injury.

There are different types of difficult patients who should be precisely identified for their management. These patients seek appropriate medical care which is not always provided. However, some may have unrecognized pathological illnesses, especially personality or psychiatry disorders. Clinical communications may be altered by professional and situational factors. In some circumstances, clinical symptoms are medically unexplainable or poorly defined as part of a disease or syndrome. Organic disease should be ruled out before patients are classified as having a somatoform disorder. Diagnosis may be delayed when symptoms are not properly evaluated therefore causing serious health consequences. Clinical competence, empathy, and high quality communication is required to succeed in difficult clinical encounters.Keywords: physician–patient communication, barriers to communication, expert patient

  17. Louis Pasteur surgical revolution.

    Toledo-Pereyra, Luis H

    2009-01-01

    Louis Pasteur (1822-1895) is considered the most notable medical scientist of his time and perhaps one of the most distinguished of all times in the history of medicine. From Dole in France to Paris, from a student of crystals to "living ferments," and from chemistry to biology and medicine, Pasteur changed the world for the benefit of humanity. The genius of Pasteur dealt with the most pressing issues of his time, basing the germ theory on the effects that microorganisms had on fermentation and putrefaction of organic matter, which gave birth to the science of bacteriology. Many other difficult problems in medicine and biology were tackled by Pasteur, culminating in the spectacular results seen with the treatment of rabies. Surgery was no exception to the scientific conquests of Pasteur. The transformation of the surgical world arose from the antiseptic concepts of Lister that were based on the germ theory of the disease, which had been derived from the germ theory of fermentation and putrefaction discovered by Pasteur. The acceptance of these principles represented the surgical revolution brought on by the science of Pasteur, a revolution that is now accepted in our daily care of surgical patients.

  20. Hand function after nerve repair.

    Lundborg, G; Rosén, B

    2007-02-01

    Treatment of injuries to major nerve trunks in the hand and upper extremity remains a major and challenging reconstructive problem. Such injuries may cause long-lasting disabilities in terms of lost fine sensory and motor functions. Nowadays there is no surgical repair technique that can ensure recovery of tactile discrimination in the hand of an adult patient following nerve repair while very young individuals usually regain a complete recovery of functional sensibility. Post-traumatic nerve regeneration is a complex biological process where the outcome depends on multiple biological and environmental factors such as survival of nerve cells, axonal regeneration rate, extent of axonal misdirection, type of injury, type of nerve, level of the lesion, age of the patient and compliance to training. A major problem is the cortical functional reorganization of hand representation which occurs as a result of axonal misdirection. Although protective sensibility usually occurs following nerve repair, tactile discriminative functions seldom recover--a direct result of cortical remapping. Sensory re-education programmes are routinely applied to facilitate understanding of the new sensory patterns provided by the hand. New trends in hand rehabilitation focus on modulation of central nervous processes rather than peripheral factors. Principles are being evolved to maintain the cortical hand representation by using the brain capacity for visuo-tactile and audio-tactile interaction for the initial phase following nerve injury and repair (phase 1). After the start of the re-innervation of the hand (phase 2), selective de-afferentation, such as cutaneous anaesthesia of the forearm of the injured hand, allows expansion of the nerve-injured cortical hand representation, thereby enhancing the effects of sensory relearning. Recent data support the view that training protocols specifically addressing the relearning process substantially increase the possibilities for improved

    2009-01-01

    Nephrology in Rome began in the 1960s with the arrival of Ernico Fiaschi in the wake of Cataldo Cassano at the Institute of Medical Pathology (later on Clinica Medica II). A group of doctors interested in nephrology was set up, with among them Giulio A. Cinotti, who was to become full professor of nephrology at the University of Rome ''La Sapienza'' in 1980. By the end of the 1960s, the renal transplant activity had become an important asset at the Institute of Surgical Pathology (later on Clinica Chirurgica II) thanks to Paride Stefanini. A chair of surgical nephrology was instituted at the Urology Clinics of Ulrico Bracci; the chair was first held by Nicola Cerulli, who developed an intensive hemodialysis program. Around the same time, the Center for the Research and Treatment of Arterial Hypertension and Kidney Diseases became operational at the hospitals of Rome (under the responsibility of Vito Cagli at the Policlinico Umberto I), while a nephrology and dialysis unit, directed by Giancarlo Ruggieri, was set up at the San Giacomo Hospital. Many nephrology-related ''cultural'' activities started to be undertaken thanks to the ''Gruppo Laziale di Nefrologia Medica e Chirurgica'' founded by Drs Cagli, Cerulli, and Cinotti. Two national congresses were organized by Giulio Cinotti in 1979 (Fiuggi) and 1992 (Rome).

    Schwannomas are benign tumours arising from Schwann cells of the peripheral nerve sheath. They are relatively frequent in the head and neck region (25-45%) but rarely involve in the sinonasal tract (4%). The authors outline the diagnostic difficulties and the problems in choosing the best surgical approach in two atypical cases of sinonasal Schwannomas. In the first case reported clinical data, sex and age of the patient, nasal endoscopy and angio-MRI led us to suspect an angiofibroma; therefore, we approached the case without a biopsy performing a preoperative selective embolization followed by an endoscopic resection. In the second case, due to initial visual symptoms and to the ethmoid-orbital compartment involvement, we performed a sinonasal endoscopy and collected a biopsy which resulted to be fundamental in the diagnostic assessment. Tumour excision was then obtained throughout an intracranial/endonasal approach. The two presented cases revealed the presence of cystic Schwannomas. In the first case, diagnosis was made only post-operatively after histological examination. Patients underwent complete surgical excision by means of an endoscopic sinonasal approach, in the second case associated to a left frontal craniotomy. The patients showed no signs of recurrence at a 9 months follow-up. Nasal endoscopy was extremely important in making the diagnosis, allowing an accurate assessment of the tumour extension and a biopsy. The diagnosis of sinonasal Schwannomas remains challenging; sometimes, clinical behaviour and modern imaging may be misleading. The diagnostic and therapeutic importance of sinonasal endoscopy is emphasised in the two presented cases.

    Krueger, Heidi; David, Shannon

    2016-12-01

    Clinical Scenario: There are 2 approaches available for surgical repair of the Achilles tendon: open or percutaneous. However, there is controversy over which repair is superior. Focused Clinical Question: Which type of surgery is better in providing the best overall patient outcome, open or percutaneous repair, in physically active men and women with acute Achilles tendon ruptures? Summary of Search, "Best Evidence" Appraised, and Key Findings: The literature was searched for studies of level 3 evidence or higher that investigated the effectiveness of open repair versus percutaneous repair on acute Achilles tendon ruptures in physically active men and women. The literature search resulted in 3 studies for possible inclusion. All 3 good-quality studies were included. Clinical Bottom Line: There is supporting evidence to indicate that percutaneous repair is the best option for Achilles tendon surgery when it comes to the physically active population. Percutaneous repair has faster surgery times, less risk of complications, and faster recovery times over having an open repair, although it is acknowledged that every patient has a different situation and best individual option may vary patient to patient.

    The adolescents in great distress, because of ruptures in the course of their lives and of their chaotic family environment, need educational and social actions. The consensual point of view is that responding to the needs of the so called "difficult adolescents" implies the involvement of educational, therapeutic and judicial services. Nevertheless, the usual tendency to categorize the users with the idea it will permit to guide them to the appropriate skill field and the transgressive characteristic of these adolescents' behaviours lead all these services to reject them and send them to the two other services.

    Prisoners, on remand or convicted, can be placed for a variable amount of time in a unit for difficult patients if their pathological mental state so requires. For the most part, their therapeutic care does not depend on their status as prisoner. The treatments provided are those indicated for their psychological pathologies and their potential or known dangerousness. However, some administrative measures make a distinction between their treatment and that of non-prisoner patients placed in these secure psychiatric units. Copyright © 2016.

    2010-01-01

    The present analyses of different surgical training systems show that training of surgical residents significantly contributes to hospital costs. These are predominantly caused by prolonged operation times of residents with increased work load for other staff members in the operating room. In addition, the productivity of surgical residents is less compared to experienced surgeons. On the other hand, hospital managements save money by the lower standard wages paid to the residents. The amount of educational costs is difficult to determine because surgical training takes place as on the job training. Therefore, from an economic point of view, the two products patient care and surgical training are difficult to separate. There are no reliable cost analyses available for the German training system. At present surgical training is indirectly financed by the DRG (diagnosis-related groups) flat rates of the health insurance. Possible options of financing the surgical training are additional funding from the health department or redistribution with supplemental payment for those surgical departments which contribute significantly more to the residents' training. Statements of medical associations, health departments and health insurances demonstrate the difficulty to come to an agreement concerning the finances of the training system. Despite this controversial discussion it should be taken into consideration that there is no alternative to a high quality surgical training as this is the basis for an effective health system.

    Schleich, Florence; Demarche, Sophie; Louis, Renaud

    2016-01-01

    Difficult asthma is a heterogeneous disease of the airways including various types of bronchial inflammation and various degrees of airway remodeling. Therapeutic response of severe asthmatics can be predicted by the use of biomarkers of Type2-high or Type2-low inflammation. Based on sputum cell analysis, four inflammatory phenotypes have been described. As induced sputum is timeconsuming and expensive technique, surrogate biomarkers are useful in clinical practice. Eosinophilic phenotype is likely to reflect ongoing adaptive immunity in response to allergen. Several biomarkers of eosinophilic asthma are easily available in clinical practice (blood eosinophils, serum IgE, exhaled nitric oxyde, serum periostin). Neutrophilic asthma is thought to reflect innate immune system activation in response to pollutants or infectious agents while paucigranulocytic asthma is thought to be not inflammatory and characterized by smooth muscle dysfunction. We currently lack of user-friendly biomarkers of neutrophilic asthma and airway remodeling. In this review, we summarize the biomarkers available for the management of difficult asthma.

  16. Honey bees selectively avoid difficult choices.

    2013-11-19

    Human decision-making strategies are strongly influenced by an awareness of certainty or uncertainty (a form of metacognition) to increase the chances of making a right choice. Humans seek more information and defer choosing when they realize they have insufficient information to make an accurate decision, but whether animals are aware of uncertainty is currently highly contentious. To explore this issue, we examined how honey bees (Apis mellifera) responded to a visual discrimination task that varied in difficulty between trials. Free-flying bees were rewarded for a correct choice, punished for an incorrect choice, or could avoid choosing by exiting the trial (opting out). Bees opted out more often on difficult trials, and opting out improved their proportion of successful trials. Bees could also transfer the concept of opting out to a novel task. Our data show that bees selectively avoid difficult tasks they lack the information to solve. This finding has been considered as evidence that nonhuman animals can assess the certainty of a predicted outcome, and bees' performance was comparable to that of primates in a similar paradigm. We discuss whether these behavioral results prove bees react to uncertainty or whether associative mechanisms can explain such findings. To better frame metacognition as an issue for neurobiological investigation, we propose a neurobiological hypothesis of uncertainty monitoring based on the known circuitry of the honey bee brain.

    In conclusion, from our own experience of laparoscopic surgery in DRC, we strongly believe that there is no reason to develop inguinal laparoscopic repair in developing countries. Laparoscopic repairs are more expensive and more difficult to perform and to learn. The next step of abdominal wall repairs in the developing world should focus on teaching the surgeons to use either commercial or low-cost mosquito meshes in open repairs and assessing the results of these procedures in such challeng...

    Full Text Available Diaphragmatic injuries are relatively rare and result from either blunt or penetrating trauma. Regardless of the mechanism, diagnosis is often missed and high index of suspicion is vital. The clinical signs associated with a diaphragmatic hernia can range from no outward signs to immediately life-threatening respiratory compromise. Establishing the clinical diagnosis of diaphragmatic injuries (DI can be challenging as it is often clinically occult. Accurate diagnosis is critical since missed DI may result in grave sequelae due to herniation and strangulation of displaced intra-abdominal organs. We present a case of polytrauma with rib fracture and delayed appearance of diaphragmatic hernia manifesting as difficult weaning from ventilatory support.

  3. Effective Climate Communication with Difficult Audiences

    2015-12-01

    Climate communication is often fraught with ideological baggage ("noise") that makes it very difficult to connect to audiences. In these cases, it is helpful to use "best practices" known from other fields of communication. Engaging audiences with authenticity, using plain language, respecting cultural and political differences, and a sprinkling of humor can go a long way toward establishing a connection. It's important to avoid common but polarizing tropes from popular media, and often quite helpful to frame climate issues in novel or unexpected ways that cut across entrenched political discourse. Emerging social science research Beyond ideology, climate change is Simple, Serious, and Solvable. Effective communication of these three key ideas can succeed when the science argument is carefully framed to avoid attack of the audience's ethical identity. Simple arguments from common sense and everyday experience are more successful than data. Serious consequences to values that resonate with the audience can be avoided by solutions that don't threaten those values.

    Full Text Available It is important to assess patients of difficult/therapy resistant asthma carefully in order to identify whether there are any correctable factors that may contribute to their poor control. It is critical to make a diagnosis of asthma and to exclude other airway diseases. A 65-years-old lady presented with repeated acute episodes of dyspnoea and wheezing. She was on regular medication for bronchial asthma for 18 years. There was no history of foreign body aspiration or loss of consciousness. Her chest radiograph was normal. She showed poor response to corticosteroids and bronchodilators. Fibreoptic bronchoscopy (FOB showed intracordal cyst of the left vocal cord and 1cm size irregular piece of betel nut in right main bronchus, which was removed endoscopically with the help of dormia basket, following which her condition improved and asthma was controlled on inhaled bronchodilators.

    Dedicated computing resources are expensive to develop, maintain, and administrate. Frequently, research groups require bursts of computing power, during which progress is still limited by available computing resources. One way to alleviate this bottleneck would be to use additional computing resources. Today, many computing devices remain idle most of the time. Passive volunteer computing exploits this unemployed reserve of computing power by allowing device-owners to donate computing time on their own devices. Another complementary way to alleviate bottlenecks in computing resources is to use more efficient algorithms. Engaging volunteer computing employs human intuition to help solve challenging problems for which efficient algorithms are difficult to develop or unavailable. Designing engaging volunteer computing projects is challenging but can result in high-quality solutions. Here, we highlight four examples. © 2017 The Protein Society.

    2014-01-01

    Difficulties with airway management are often caused by anatomic abnormalities due to previous oral surgery. We performed general anesthesia for a patient who had undergone several operations such as hemisection of the mandible and reconstructive surgery with a deltopectoralis flap, resulting in severe maxillofacial deformation. This made it impossible to ventilate with a face mask and to intubate in the normal way. An attempt at oral awake intubation using fiberoptic bronchoscopy was unsuccessful because of severe anatomical abnormality of the neck. We therefore decided to perform retrograde intubation and selected the cuffed oropharyngeal airway (COPA) for airway management. We inserted the COPA, not through the patient's mouth but through the abnormal oropharyngeal space. Retrograde nasal intubation was accomplished with controlled ventilation through the COPA, which proved to be very useful for this difficult airway management during tracheal intubation even though the method was unusual.

Hayatabad Medical Complex Peshawar, Pakistan, from January 2007 to December 2011. Material and Methods. All male patients presenting with hypospadias irrespective of their ages were included in the study. The data were acquired from the hospital’s database and analyzed with Statistical Package for Social Sciences (SPSS. Results. A total of 428 patients with mean age of 8.12 ± 5.04 SD presented for hypospadias repair. Midpenile hypospadias were the most common. Chordee, meatal abnormalities, cryptorchidism, and inguinal hernias were observed in 74.3%, 9.6%, 2.8%, and 2.1% cases, respectively. Two-stage (Bracka and TIP (tubularized incised urethral plate repairs were performed in 76.2% and 20.8% of cases, respectively. The most common complications were edema and urethrocutaneous fistula (UCF. The complications were significantly lower in the hands of specialists than residents (P-value = 0.0086. The two-stage hypospadias repair resulted in higher complications frequency than single-stage repair (P value = 0.0001. Conclusion. Hypospadias surgery has a long learning curve because it requires a great deal of temperament, surgical skill and acquaintance with magnifications. Single-stage repair should be encouraged wherever applicable due to its lower postoperative complications.

  8. Schwann cells for spinal cord repair

    Directory of Open Access Journals (Sweden)

    Oudega M.

    2005-01-01

    Full Text Available The complex nature of spinal cord injury appears to demand a multifactorial repair strategy. One of the components that will likely be included is an implant that will fill the area of lost nervous tissue and provide a growth substrate for injured axons. Here we will discuss the role of Schwann cells (SCs in cell-based, surgical repair strategies of the injured adult spinal cord. We will review key studies that showed that intraspinal SC grafts limit injury-induced tissue loss and promote axonal regeneration and myelination, and that this response can be improved by adding neurotrophic factors or anti-inflammatory agents. These results will be compared with several other approaches to the repair of the spinal cord. A general concern with repair strategies is the limited functional recovery, which is in large part due to the failure of axons to grow across the scar tissue at the distal graft-spinal cord interface. Consequently, new synaptic connections with spinal neurons involved in motor function are not formed. We will highlight repair approaches that did result in growth across the scar and discuss the necessity for more studies involving larger, clinically relevant types of injuries, addressing this specific issue. Finally, this review will reflect on the prospect of SCs for repair strategies in the clinic.

    Chronic rotator cuff tears present a clinical challenge, often with poor outcomes after surgical repair. Degenerative changes to the muscle, tendon, and bone are thought to hinder healing after surgical repair; additionally, the ability to overcome degenerative changes after surgical repair remains unclear. The purpose of this study was to evaluate healing outcomes of muscle, tendon, and bone after tendon repair in a model of chronic rotator cuff disease and to compare these outcomes to those of acute rotator cuff injuries and repair. The hypothesis was that degenerative rotator cuff changes associated with chronic multitendon tears and muscle unloading would lead to poor structural and mechanical outcomes after repair compared with acute injuries and repair. Controlled laboratory study. Chronic rotator cuff injuries, induced via detachment of the supraspinatus (SS) and infraspinatus (IS) tendons and injection of botulinum toxin A into the SS and IS muscle bellies, were created in the shoulders of rats. After 8 weeks of injury, tendons were surgically reattached to the humeral head, and an acute, dual-tendon injury and repair was performed on the contralateral side. After 8 weeks of healing, muscles were examined histologically, and tendon-to-bone samples were examined microscopically, histologically, and biomechanically and via micro-computed tomography. All repairs were intact at the time of dissection, with no evidence of gapping or ruptures. Tendon-to-bone healing after repair in our chronic injury model led to reduced bone quality and morphological disorganization at the repair site compared with acute injuries and repair. SS and IS muscles were atrophic at 8 weeks after repair of chronic injuries, indicating incomplete recovery after repair, whereas SS and IS muscles exhibited less atrophy and degeneration in the acute injury group at 8 weeks after repair. After chronic injuries and repair, humeral heads had decreased total mineral density and an altered

    We report a case of a primary parahiatal hernia that was repaired laparoscopically with a composite mesh. A 51-year-old woman presented with vomiting and epigastric pain. CT scan showed a giant paraesophageal hernia with intrathoracic gastric volvulus. Intraoperatively, a diaphragmatic muscular defect was found lateral to an attenuated left crus of the diaphragm, distinct from the normal esophageal hiatus. The defect ring was fibrotic, making a tension-free primary repair difficult. A laparoscopic mesh repair was performed with a composite mesh, which was covered with the hernia sac to prevent potential erosion into the esophagus or stomach. Recovery was uneventful and the patient was discharged on the 5 days postoperatively. She remained asymptomatic at subsequent follow-up. Laparoscopic repair of parahiatal hernia can be safely performed. In circumstances where a large or fibrotic defect prevents a tension-free primary repair, the use of a composite mesh can provide effective repair of the hernia.

    2009-03-01

    Congenital hyperinsulinism is a functional disorder of insulin secretion. In its diffuse severe form, it is traditionally treated with over 95% pancreatectomy. However, even after this procedure normoglycemia is not always achieved. Non-surgical therapy with frequent or continuous feeding, medication and close monitoring is another alternative. In this review we compare the two approaches to this condition focusing on early complications, diabetes, neurological outcome and home management issues. Early complications of pancreatectomy include mechanical, metabolic and infectious complications. Non-surgical interventions can be complicated by unwarranted effects of medications and of invasive procedures. Diabetes occurs with both approaches but much less frequently and years later with non-surgical treatment. Regarding neurodevelopmental outcome, most data come from heterogeneous groups. Nevertheless, it appears that outcome is not adversely affected by avoiding surgery. Home management is far more difficult for the non-surgical form. When the non-surgical approach is successful in achieving normoglycemia and parents are highly motivated, this mode of therapy should be considered.

    Asthma continues to be one of the greatest burdens to healthcare resources throughout the developed world. In most cases, good symptom control can be achieved with low-dose inhaled corticosteroids, and can be cared for in the primary and secondary healthcare systems. However, there is a group in whom control is not achieved despite high-dose inhaled corticosteroids and maximal add-on therapies; these are children with problematic severe asthma that should be referred to a specialist team for further investigation and management. In this review we aimed to provide an evidence-based guide for pediatricians providing care for children with asthma in secondary healthcare settings. The review focuses on a proposed investigation and management strategy for children aged between 6 and 16 years with problematic severe asthma, and is supported as far as possible by evidence from the literature. We first address recent advances in nomenclature and then discuss our proposed course of investigation and management of these children. Distinction of children with true, severe, therapy-resistant asthma from those with asthma that is difficult to treat because of unaddressed underlying modifiable factors is critical and is discussed in detail.

    This paper describes a method of advanced torpedoing a roof difficult to break down at the Polysaevskaya coal mine. It consists in placing explosive charges in the roof ahead of the coal face. Three schemes were tested: boreholes were drilled parallel to the face, perpendicular or inclined at an angle to the face. Boreholes were 112 mm in diameter and their length ranged from 30 to 100 m, distance between the boreholes amounted to 20 m. 6ZhV ammonite explosive, 90 mm in diameter and 500 mm long, were used. Torpedos were 2 m long, and separated by 3 to 4 m long air pockets. When a roof characterized by a high compressive strength coefficient (about 10 on the Protod'yakonov scale) was torpedoed, 250 kg of ammonite were used for a borehole 80 m long, and 160 kg for a borehole 50 m long. When borehole length was reduced to 40 m explosive consumption decreased to 117 kg. In the case of rocks with compressive strength coefficient of 6, explosive amount was two times lower. In a coal mine in which an OKP-70 face system was used applying advanced torpedoing increased labor productivity of the face by 30% and reduced cost of mining by 42%. Number of work accidents was reduced 13 times. (In Russian)

  20. Why behavior change is difficult to sustain.

    Bouton, Mark E

    2014-11-01

    Unhealthy behavior is responsible for much human disease, and a common goal of contemporary preventive medicine is therefore to encourage behavior change. However, while behavior change often seems easy in the short run, it can be difficult to sustain. This article provides a selective review of research from the basic learning and behavior laboratory that provides some insight into why. The research suggests that methods used to create behavior change (including extinction, counterconditioning, punishment, reinforcement of alternative behavior, and abstinence reinforcement) tend to inhibit, rather than erase, the original behavior. Importantly, the inhibition, and thus behavior change more generally, is often specific to the "context" in which it is learned. In support of this view, the article discusses a number of lapse and relapse phenomena that occur after behavior has been changed (renewal, spontaneous recovery, reinstatement, rapid reacquisition, and resurgence). The findings suggest that changing a behavior can be an inherently unstable and unsteady process; frequent lapses should be expected. In the long run, behavior-change therapies might benefit from paying attention to the context in which behavior change occurs.

There has been little exploration of the decisions physicians face when providing care across language barriers. The authors offer a conceptual framework to aid physicians in thinking through difficult choices about language services and provide responses to common questions encountered in the care of patients with limited English proficiency. Specifically, they describe 4 factors that should inform the decision to call an interpreter (the clinical situation, degree of language gap, available resources, and patient preference), discuss who may be an appropriate interpreter, and offer strategies for when a professional interpreter is not available. The authors use a hypothetical case to illustrate how decisions about language services may evolve over the course of an interaction. This conceptual and practical approach can help clinicians to improve the quality of care provided to patients with limited English proficiency.

  2. Definitions of Complexity are Notoriously Difficult

    Schuster, Peter

    Definitions of complexity are notoriously difficult if not impossible at all. A good working hypothesis might be: Everything is complex that is not simple. This is precisely the way in which we define nonlinear behavior. Things appear complex for different reasons: i) Complexity may result from lack of insight, ii) complexity may result from lack of methods, and (iii) complexity may be inherent to the system. The best known example for i) is celestial mechanics: The highly complex Pythagorean epicycles become obsolete by the introduction of Newton's law of universal gravitation. To give an example for ii), pattern formation and deterministic chaos became not really understandable before extensive computer simulations became possible. Cellular metabolism may serve as an example for iii) and is caused by the enormous complexity of biochemical reaction networks with up to one hundred individual reaction fluxes. Nevertheless, only few fluxes are dominant in the sense that using Pareto optimal values for them provides near optimal values for all the others...

    Full Text Available Repair of the mitral valve is the treatment of choice for mitral valve regurgitation when the anatomy is favorable. It is well known that mitral valve repair enjoys better clinical and functional results than any other type of valve substitute. This fact is beyond doubt regardless of the etiology of the valve lesion and is of particular importance in degenerative diseases.This review analyzes the most important advances in the knowledge of the anatomy, pathophysiology, and chordal function of the mitral valve as well as the different alternatives in the surgical repair and clinical results of the most prevalent diseases of the mitral valve. An attempt has been made to organize the acquired information available in a practical way.

    Visceral artery aneurysm (VAA) is a rare entity but increased use of abdominal imaging has led to an increased prevalence. Rupture is related to a high mortality rate. Open repair, endovascular treatment and laparoscopic techniques have been described as treatment options. In this systematic review we describe the surgical options for treating VAA. A literature search identified articles focussing on the key issues of visceral artery aneurysms and surgical options using the Pubmed and Cochrane databases. Case reports dominate the literature about VAA. Twenty-seven small case series and ten review articles have been published in the last 20 years concerning the surgical options for VAA. The evidence does not exceed level 3. Surgical treatment is dictated by both patient and aneurysm characteristics. Whether VAA should be treated largely depends upon age, gender, presence of hypertension (e.g. in renal aneurysm), aneurysm size and presentation. Aneurysm size and characteristics, anatomical location and presence of collateral circulation dictate the surgical option to be chosen. The mortality and morbidity rates after elective open repair are low. Literature about surgical options for treating VAA remains scarce. Only a few clinical trials have shown the possibilities and results of open surgical repair. In general, there is no consensus on the surgical treatment of VAA and the highest level of evidence is based upon expert opinions.

    Hypospadias is an embryological disorder that results in an abnormal ventral positioning of the urethral meatus. Among multiple surgical techniques described to correct this anomaly, the use of buccal mucosa grafts has gained popularity among pediatric urologists, pediatric surgeons and plastic surgeons. Buccal mucosa grafts have shown favorable histological changes that result in an excellent scaffold for urethral reconstructive surgery. This review describes the evolution of the use of buccal mucosa grafts in hypospadias repair.

    2013-12-01

    Full Text Available Introduction. Esophageal atresia encompasses a group of congenital anomalies comprising of an interruption of the esophageal continuity with or without a persistent communication with the trachea. Esophageal atresia with tracheoesophageal fistula (type C accounts for 85% of all esophageal atresia. Minimally invasive approach to correct esophageal atresia with distal fistula is becoming more generally accepted. The outcome of these technique are critically analyzed and compared with results from open repair. We present one case of type IIIB esophageal atresia treated by a thoracoscopic approach. Case Report. The patient was a 2-days-old infant male, weight 3 kg with esophageal atresia and distal tracheoesophageal fistula without other associated disease. A polidramanios was detected in prenatal age by a prenatal ultrasound evaluation. He underwent to a thoracoscopic repair of the defect. The operation was approached through the right chest using a three-trocar technique (three 5-mm with the patient placed in a three-quarter prone position. The azygos vein was ligated by Ligature device. The fistula was ligated by two resorbable stiches suture and dissected, the proximal esophagus was opened and an anastomosis was made over a 6 Ch nasogastric tube with interrupted and resorbable stiches suture. On the postoperative day 7, gastrografin swallow was performed and oral feeding was started. The patient’s six month upper Gastrointestinal barium studies was normal. Discussion and conclusion. Thoracoscopic repair of esophageal atresia is considered to be one of the more advanced and most difficult pediatric surgical procedures and it undoubtely has necessary an elevated learning curve. The minimally invasive approach was larged accepted in the last ten years also for the well documented sequelae of traditional open repair of esophageal atresia. More experience is needed to determine the exact place of this approach.

    2014-01-01

    Full Text Available Introduction: Despite the improved techniques of repair of cleft palate, fistula occurrence is still a possibility either due to an error in the surgical technique or due to the poor tissue quality of the patient. Though commonly the fistula closure is established by use of local flaps but at times the site and the size of the fistula make use of local flaps for its repair a remote possibility. The use of tongue flaps because of the central position in the floor of the mouth, mobility and the diversity of positioning the flaps make it a method of choice for closure of anterior palatal fistulae than any other tissues. The aim of this study was to analyse the utility of tongue flap in anterior palatal fistula repair. Materials and Methods: We had 41 patients admitted to our hospital during the period 2006-2012 for repair of palatal fistula and were enrolled into the study. In the entire 41 cases, fistula was placed anteriorly. The size of the fistulae varied from 2 cm × 1.5 cm to 5.5 cm × 3 cm. The flaps were divided after 3-week and final inset of the flap was done. Observation and Result: None of the patients developed flap necrosis, in one case there was the dehiscence of the flap, which was reinset and in one patient there was bleeding. None of our patients developed functional deformity of the tongue. Speech was improved in 75% cases. Conclusion: Leaving apart its only drawback of two-staged procedure and transient patient discomfort, tongue flap remains the flap of choice for managing very difficult and challenging anterior palatal fistulae.

    Intramedullary Ependymomas are uncommon tumors that can occur within the medullary substance of the spinal cord. Despite this difficult location, they are typically benign tumors that can most often be removed completely with an acceptable surgical risk. Therefore, the recommended management approach is usually surgical excision. This review will consider the historical context in which surgeons began treating these tumors and then review the more recent literature that guides their current management.

    Difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. Mediastinal masses are not common findings, but are important variables. Bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. We present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchogenic cyst was detected in this patient. The patient had history of asthma since she was eight months old. She had a history of several asthma attacks which had partly responded to asthma management. During the last episodes of asthma attacks, she was hospitalized in Pediatric Intensive Care Unit. Imaging studies showed a 4x3 cm mass in the posterior part of the thoracic cavity that had led to tracheal narrowing was found for which the patient underwent thoracotomy and in surgical exploration a cyst that had compressed the thoracic trachea. Pathological examination of the cyst revealed a bronchogenic cyst. Bronchogenic cyst is an uncommon developmental abnormality but in a patient with obstructive pattern of airways it should be considered in differential diagnosis of asthma, especially if the asthma management is not successful.

    Hospital malnutrition is an insidious problem which is responsible for many complications. Critically ill patients are frequently hypermetabolic with increased nutritional requirements, and are exposed to the risk of underfeeding. The case report presents the case of a patient which stayed 22 days in the intensive care unit (ICU), and whose nutritional support failed: he ultimately died of surgical and infectious complications. An optimal support includes a early metabolic support provided as glucose-insulin-potassium infusion and antioxidant micronutrients, with an enteral nutrition initiated on days 3 or 4. It is frequently difficult to reach energy targets with exclusive enteral nutrition: if the latter is not reached after 5-6 days of enteral feeding, combination with parenteral nutrition enables worsening of the energy deficit. Transition to oral feeding is another critical event which may expose the patient to underfeeding: prescription of oral supplements and/or maintenance of overnight enteral feeding providing 50-75% of energy requirements helps overcome this period. The case illustrates the importance of monitoring daily and cumulated energy balance.

    Objectives To investigate outcomes after surgical repair of distal biceps tendon rupture and the influence of arm dominance on isokinetic flexion and supination results. Background/Purpose While relatively uncommon, rupture of the distal biceps tendon can result in significant strength deficits, for which surgical repair is recommended. The purpose of this study was to assess patient reported functional outcomes and muscle performance following surgery. Methods A sample of 23 participants (22 males, 1 female), who had previously undergone surgical repair of the distal biceps tendon, were re-examined at a minimum of one year after surgery. Biodex isokinetic elbow flexion and supination testing was performed to assess strength (as measured by peak torque) and endurance (as measured by total work and work fatigue). The Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Mayo Elbow Performance Scale (MEPS) were used to assess participants' subjectively reported functional recovery. Results At a mean of 7.6 years after surgical repair, there were no differences between the repaired and uninvolved elbows in peak torque (p = 0.47) or total work (p = 0.60) for flexion or supination. There was also no difference in elbow flexion work fatigue (p = 0.22). However, there was significantly less work fatigue in supination, which was likely influenced by arm dominance, as most repairs were to the dominant arm, F(1,22)=5.67, p = 0.03. Conclusion The long-term strength of the repaired elbow was similar to the uninvolved elbow after surgery to the distal biceps tendon. Endurance of the repaired elbow was similar in flexion but greater in supination, probably influenced by arm dominance. Study design Retrospective case series Level of Evidence Level 4 PMID:27904798

    Objective To investigate the feasibility of restoring erectile function by repairing abla-ted cavernous nerve with neural stem cell grafts. Methods Forty-two male Sprague-Dawley rats (3-4 months old, weighing 300-400 g) were randomly divided into three groups: sham-operated controls (n = 14 ) subject to pelvic exploration without transection of the cavernous nerve; nerve ablation group (n = 14) having a 3 nun segment of cavernous nerve excised bilaterally; graft group (n = 14) having a 3 mm segment of cavernous nerve excised bilaterally, followed by immediate neural stem cell grafting. Two and 4 months postoperatively the rats of each group were electrostimulated to the cavernousal nerves to determine potency. Corpora cavernosa were harvested and nNOS-positive nerve fibers were examined by using immunohisto-chemistry. Results At the 2nd month postoperatively, electrical stimulation produced no erections in the nerve ablation or the graft group and 100 % erections in the sham-operated group. There was no significant difference in the nNOS-positive nerve fibers between the nerve ablation group and the graft group. At the 4th month postoperatively, 57. 14% of the grafted nerves produced erections upon electrical stimulation, significantly different from that in the nerve ablation group (7. 19% ). The nNOS-positive nerve fibers in the graft group (86. 0 ± 13.4) significantly differed from those in the nerve ablation group (26. 5±4. 3), and approximated the level of the sham-operated group (95.1 ± 7.7). Conclusion Neural stem cell graft-ing can be an effective method in restoring potency after injury.%目的 观察神经干细胞移植修复损伤的海绵体神经从而恢复勃起功能的可行性.方法 42只雄性SD大鼠(3~4个月龄和体质量300~400 g)随机分为假手术组、神经干细胞移植组和神经损伤组,每组14只.2、4个月后,海绵体神经电刺激检测大鼠阴茎勃起功能,免疫组织化学法检测海绵体内一氧化氮

  17. Large myelomeningocele repair

    2011-01-01

    Full Text Available Background: Wound closure is accomplished in most cases of myelomeningocele (MMC by undermining of the skin edges surrounding the defect. However, large defects cannot be closed reliably by this simple technique. Due to the technical challenge associated with large MMC, surgeons have devised different methods for repairing large defects. In this paper, we report our experience of managing large defects, which we believe bears a direct relationship to decrease the incidence of wound complications. Materials and Methods: Forty children with large MMCs underwent surgical repair and represent our experience. We recommend using all hairy skin around the defect as a way to decrease the tension on the edges of the wound and the possible subsequent necrosis. It is our experience that vertical incision on one or two flanks parallel to the midline can decrease the tension of the wound. Moreover, ventriculo-peritoneal shunting for children who developed hydrocephalus was performed simultaneously, which constitutes another recommendation for preventing fluid collection and build up of pressure on the wound. Results: Patients in this study were in the age range of 2 days to 8 years. The most common location of MMC was in the thoracolumbar area. All but four patients had severe weakness in lower extremities. We used as much hairy skin around the MMC sac as possible in all cases. Vertical incisions on one or both flanks and simultaneous shunt procedure were performed in 36 patients. We treated children with large MMC defects with acceptable tension-free closure. Nonetheless, three patients developed superficial skin infection and partial wound dehiscence, and they were managed conservatively. Conclusions: We recommend using all hairy skin around the MMC defect for closure of large defects. In cases that were expected to be at a higher risk to develop dehiscence release incisions on one or two flanks towards the fascia were found to be useful. Simultaneous

    Full Text Available Aim: precut sphincterotomy refers to a variety of endoscopic techniques that are used in order to access the bile duct when conventional methods of cannulation have failed. There are not significant data (such as efficacy, safety about the use of different techniques of precutting at the same session. We have described our experience with combined precut sphincterotomy (CPS and we have compared our results to the use of an isolated precut. Patients and methods: we have performed 247 precuts of a total of 2.390 ERCPs. Patients were distributed according to the type of precut practiced: Needle-knife, transpancreatic and combined precut sphincterotomies. "Combined precut" consisted in performing first a transpancreatic sphincterotomy and, if the access was not achieved, then performing a needle-knife sphincterotomy in the same session. The data about safety and efficacy were prospectively collected. The complications were defined according to the consensus criteria. Results: we performed precutting techniques in 247 patients. Needle-knife, transpancreatic, and combined precuts were performed in 125 (6.9%, 74 (4.1% and 48 (2.6% patients, respectively. Bile duct cannulation was successful in 48 patients (100% in the group of combined precut, 121 patients (96.8% in the transpancreatic group, and 67 patients (90.5% in the needle-knife group (p = 0.03. There were not differences in complications rates between the three groups. There was no pancreatitis in the combined precut group. The complications were successfully managed with conservative treatment. Conclusions: combined precut sphincterotomy seems to be a safe and successful technique in those cases of difficult bile duct cannulation.

    Our novel technique of pen torch transillumination (PTI) uses a cheap and easily available instrument (Penlite-LP212(®), Energizer(®), Missouri, USA) to visualize superficial veins invisible to the naked eye. We evaluate the efficacy of PTI in improving venepuncture success rate (SR) for patients with poor venous access. This prospective randomized controlled trial looked at adult patients (n = 69) aged 21-90 with difficult venous access (history of ≥3 consecutive attempts required for successful cannulation during the current admission) requiring non-emergent venepuncture. Patients underwent venepuncture over the upper-limb using one of the following: conventional venepuncture (control); Veinlite(®) EMS (TransLite(®), Texas, USA), a commercial transillumination device; PTI. Outcome measures were: successful cannulation within 2 attempts and total duration of venepuncture. Fisher's exact and Kruskal-Wallis tests were performed. A significantly larger number of patients had successful venepuncture within 2 attempts using PTI (22/23, 95.7%) and Veinlite (23/23, 100%), compared to the controls (7/23, 30.4%) (p < 0.05). The total duration required for successful venepuncture was significantly shorter for Veinlite (mean 3.7 min, 1.0-5.3 min) and PTI (mean 8.5 min, range 1.08-27 min) compared to the controls (mean 23.2 min, range 1.88-46.5 min) (p < 0.05). PTI allows users to visualize veins invisible to the naked eye. Thrombosed/tortuous veins, branch points and valves, are easily identified and avoided. It has comparable efficacy to Veinlite(®) and is cheaper (Veinlite(®)-USD 227 vs. Penlite-LP212(®)-USD 7.00) and more easily available. PTI improves patient care, especially in developing regions where costs are a concern.

  1. COMPARATIVE STUDY OF LICHTENSTEIN VERSUS DESARDA REPAIR FOR INGUINAL HERNIA

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available BACKGROUND Inguinal hernia repair is the most frequently performed operation in any general surgical unit. The Bassini’s, Shouldice and other tissue-based techniques are still being acceptable for primary inguinal hernia repair. Desarda’s technique is originally a tissue based hernia repair using an undetached strip of external oblique aponeurosis to strengthen the posterior wall of the inguinal canal. The aim of the present study was to compare Lichtenstein hernia repair and Desarda herniorrhaphy. METHODS A total of 40 patients with primary unilateral inguinal hernia were subjected either to Desarda herniorrhaphy or Lichtenstein hernioplasty. The patients were followed in terms of recurrence rate, post-operative complications, convalescence, chronic pain and cost effectiveness. RESULTS During the followup all patients had either mild or moderate pain, but the pain intensity was more in Lichtenstein repair compared to Desarda repair in the immediate postoperative period. In Lichenstein repair patients had chronic groin pain even at the end of one year, but none of the patients in Desarda repair had chronic groin pain. Complications such as seroma and wound infection were less in Desarda repair. Time taken to resume normal activities was significantly less in case of Desarda herniorrhaphy; however, there was no recurrence observed in both the groups during the followup period. Average cost incurred for Desarda repair was significantly less than Lichtenstein repair. CONCLUSION Lichtenstein method of hernia repair is simple and safe. But the mesh prosthesis has its drawbacks. Desarda hernia repair is based on physiological principles and the results are good with less convalescence period and fewer recurrences and no chronic groin pain. It is more cost effective.

    Gunshot wound injury to the external genitalia is relatively uncommon. However, if a testis isaffected in such a case, early surgical exploration should be carried out. A 16-year-old boy presented with right testicular rupture. Tunica albugineal defect could not be closed primarily. We used a Tutoplast® processed bovine pericardium to repair the defect of tunica albuginea. At his 3-month follow-up visit, there was no complication. Doppler blood flow of testis was normal. In this case, preservation of testis tissue was obtained with early exploration and repair of the big tunica albugineal defect with Tutoplast® processed pericardium.

    Full Text Available Vitiligo is a hypomelanotic disorder often difficult to treat. Different medicinal treatments such as PUNA, steroids and adjunct theraples give partial or complete repigmentation in about 60-90% cases. Moreover, vitiligo patches which are refractory to most medical therapies are acrofacial, mucosal and segmental. At the backdrop of these medicinal shortcomings, various surgical procedures and their modifications have gradually evolved. To decide why, where and when surgical interference is required, is of utmost importance. In this review different surgical modes, including some of the latest, and their future prospects are discussed.

The study has been carried out on 44 patients submitted to surgical extraction of the impacted 8th (19 upper and 25 lower) teeth. Clinical and histological controls have demonstrated the usefulness of this suture procedure, since it gives a good histological reaction and in easy and safe. Histological and clinical results have confirmed the usefulness of silk suture, presenting however the inconvenience of stitches removal and bacterial plaque on the surgical wound.

    Surgical repair of Morgagni hernias is recommended given their historically high risk of incarceration. Traditionally, such repair has been undertaken via laparotomy or thoracotomy or more recently, thoracoscopically or laparoscopically using mesh. Here, we describe a laparoscopic approach to the management of Morgagni hernias achieving a primary tissue repair without mesh implantation. This technique allows for the general benefits of minimally invasive surgery, such as less postoperative pain, reduced wound complications, decreased duration of the hospital stay, as well as offering an alternative to mesh implantation and its associated potential complications.

    Full Text Available Abstract Background This study was designed to determine the role of primary repair and to investigate the possibility of expanding indications for primary repair of colon injuries using nonselective approach. Methods Two groups of patients were analyzed. Retrospective (RS group included 30 patients managed by primary repair or two stage surgical procedure according to criteria published by Stone (S/F and Flint (Fl. In this group 18 patients were managed by primary repair. Prospective (PR group included 33 patients with primary repair as a first choice procedure. In this group, primary repair was performed in 30 cases. Results Groups were comparable regarding age, sex, and indexes of trauma severity. Time between injury and surgery was shorter in PR group, (1.3 vs. 3.1 hours. Stab wounds were more frequent in PR group (9:2, and iatrogenic lesions in RS group (6:2. Associated injuries were similar, as well as segmental distribution of colon injuries. S/F criteria and Flint grading were similar. In RS group 15 primary repairs were successful, while in two cases relaparotomy and colostomy was performed due to anastomotic leakage. One patient died. In PR group, 25 primary repairs were successful, with 2 immediate and 3 postoperative (7-10 days deaths, with no evidence of anastomotic leakage. Conclusions Results of this study justify more liberal use of primary repair in early management of colon injuries. Trial registration Current Controlled Trials ISRCTN94682396

    Echocardiographic imaging of the mitral valve before and immediately after repair is crucial to the immediate and long-term outcome. Prior to mitral valve repair, echocardiographic imaging helps determine the feasibility and method of repair. After the repair, echocardiographic imaging displays the new baseline anatomy, assesses function, and determines whether or not further management is necessary. Three-dimensional imaging has improved the assessment of the mitral valve and facilitates communication with the surgeon by providing the surgeon with an image that he/she might see upon opening up the atrium. Further advancements in imaging will continue to improve the understanding of the function and dysfunction of the mitral valve both before and after repair. This information will improve treatment options, timing of invasive therapies, and advancements of repair techniques to yield better short- and long-term patient outcomes. The purpose of this review was to connect the echocardiographic evaluation with the surgical procedure. Bridging the pre- and post-CPB imaging with the surgical procedure allows a greater understanding of mitral valve repair.

    There is a lack of consensus about the surgical management of umbilical hernias. The aim of this study is to analyze the medium-term results of 934 umbilical hernia repairs. In this study, 934 patients with an umbilical hernia underwent surgery between 2004 and 2010, 599 (64.1%) of which were evaluated at least one year after the surgery. Complications, recurrence, and the reoperation rate were analyzed. Complications were observed in 5.7 per cent of the patients. With a mean follow-up time of 35.5 months, recurrence and reoperation rates were 3.8 per cent and 4.7 per cent, respectively. A higher percentage of female patients (60.9 % vs 29 %, P = 0.001) and a longer follow-up time (47.4 vs 35 months, P = 0.037) were observed in patients who developed a recurrence. No significant differences were observed between complications and the reoperation rate in patients who underwent Ventralex(®) preperitoneal mesh reinforcement and suture repair; however, a trend toward a higher recurrence rate was observed in patients with suture repair (6.5 % vs 3.2 %, P = 0.082). Suture repair had lower recurrence and reoperation rates in patients with umbilical hernias less than 1 cm. Suture repair is an appropriate procedure for small umbilical hernias; however, for larger umbilical hernias, mesh reinforcement should be considered.

    The retromuscular or sublay repair of ventral hernias, popularized by Rives and Stoppa, requires that a layer of tissue be reapproximated dorsal to the mesh to separate the bowel from the prosthetic. This is the first report of two patients who developed bowel obstruction resulting from interparietal incarceration between the posterior rectus sheath and the prosthetic graft through a defect in this dorsal layer. Both patients underwent open retromuscular hernia repair, one with lightweight polypropylene mesh, the other with human acellular dermal matrix. Postoperatively (day 3 and day 42, respectively), the patients developed signs of bowel obstruction. Computed tomography demonstrated the herniation of the small bowel into the potential space between the prosthesis and the posterior rectus sheath. The first patient underwent successful laparoscopic repair, while the second patient had an open operation to reduce the incarcerated bowel and repair the defect. In the patient convalescing from an uneventful retromuscular hernia repair who develops signs and symptoms of a bowel obstruction, there should be a high index of suspicion that an interparietal hernia may have formed, with the small bowel herniated into the surgically created space between the prosthetic and the posterior rectus sheath.

    The management of paraesophageal hernia (PEH) can be challenging due to the lack of consensus regarding indications and principles of operative treatment. In addition, data about the pathophysiology of the hernias are scant. Therefore, the goal of this review is to shed light and describe the classification, pathophysiology, clinical presentation, and indications for treatment of PEHs, and provide an overview of the surgical management and a description of the technical principles of the repair.

    @@ Abdominal aortic aneurysm (AAA) has a high propensity to rupture. Repair of AAA by conventional surgical replacement with a graft has been the standard of treatment since the mid 1960s.Because of advances in surgical, anaesthetic and intensive care techniques, the outcome of elective open AAA repair has improved constantly. However,with the improvement of endovascular techniques,the role of open repair is being challenged.1 More and more stents are being deployed in patients because of their less invasive characteristics.2 We reviewed our ten years of experience with elective open AAA repair and recent papers about endoluminal and open repair for AAA to discuss status and future of open repair for AAA in China.

    Full Text Available A vesicovaginal fistula is one of the complications that a gynaecologist is bound to face after oncological operations, especially in postmenopausal women. Over the years there have been introduced many techniques of surgical treatment of this entity, including transabdominal and transvaginal approaches.We present a case of a 46-year-old patient who suffered from urinary leakage via the vagina due to the presence of a vesicovaginal fistula that developed after radical abdominal hysterectomy and subsequent radiotherapy. The decision was made to repair it laparoscopically due to retracted, fibrous and scarred tissue in the vaginal apex that precluded a transvaginal approach. A small cystotomy followed by an excision of fistula borders was performed. After six-month follow-up no recurrence of the disease has been noted.We conclude that laparoscopy is an interesting alternative to traditional approaches that provides comparable results.

    DNA within cells is subject to damage from various sources. Organisms have evolved a number of mechanisms to repair DNA damage. The activity of repair enzymes carries its own risk, however, because the repair of two nearby lesions may lead to the breakup of DNA and result in cell death. We propose a mathematical theory of the damage and repair process in the important scenario where lesions are caused in bursts. We use this model to show that there is an optimum level of repair enzymes within cells which optimises the cell's response to damage. This optimal level is explained as the best trade-off between fast repair and a low probability of causing double-stranded breaks. We derive our results analytically and test them using stochastic simulations, and compare our predictions with current biological knowledge.

    . Discussion: Laparoscopy has advantages over open surgery in that it is associated with less pain, shorter length of hospital stay, better cosmesis, quicker recovery, and equal efficacy. Although cases of VUF are rarely noted, the laparoscopic skill obtained through other urological procedures suggest, that laparoscopic repair may be the procedure of choice for such cases (2. The reported operative time for the laparoscopic repair of VUF in the literature varies between 140 and 220 min (3. However, laparoscopic techniques should be considered as a mode of abdominal access and should not influence the method of surgical repair. Surgical success should depend on the adherence to good technique rather than the approach. Hence, this method appears to be a viable alternative for surgeons experienced with laparoscopic suturing techniques. Conclusion: Laparoscopic repair appears to be a viable alternative for surgeons experienced with laparoscopic suturing techniques.
