Ankyloglossia or tongue-tie is a congenital anomaly affecting the tongue, which is characterized by thick, short lingual frenulum. This condition causes many difficulties such as limited tongue protrusion, breastfeeding difficulties, speech impairment and lack of self-confidence. It is very rarely associated with any other congenital craniofacial disorders such as cleft lip, X-linked cleft palate, Van der Woude syndrome, Smith-Lemli-Opitz syndrome, Orofacial digital syndrome, Beckwith Weidman syndrome or Simpson-Golabi-Behmel syndrome. This article presents a rare case of ankyloglossia associated with cleft lip treated with diode laser in a 12-year-old Indian boy who had undergone surgical correction of associated cleft lip soon after birth. Correction of ankyloglossia at a young age would lead to enhanced phonetics, improved oral hygiene, and overall personality development. PMID:26941523

To determine cataract surgical coverage, and barriers to modern cataract surgery in Nigeria. Multistage stratified cluster random sampling was used to identify a nationally representative sample of 15,027 persons aged 40+ years. All underwent visual acuity testing, frequency doubling technology visual field testing, autorefraction, and measurement of best corrected vision if <6/12 in one or both eyes. An ophthalmologist examined the anterior segment and fundus through an undilated pupil for all participants. Participants were examined by a second ophthalmologist using a slit lamp and dilated fundus examination using a 90 diopter condensing lens if vision was <6/12 in one or both eyes, there were optic disc changes suggestive of glaucoma, and 1 in 7 participants regardless of findings. All those who had undergone cataract surgery were asked where and when this had taken place. Individuals who were severely visually impaired or blind from unoperated cataract were asked to explain why they had not undergone surgery. A total of 13,591 participants were examined (response rate 89.9%). Prevalence of cataract surgery was 1.6% (95% confidence interval 1.4-1.8), significantly higher among those aged ≥70 years. Cataract surgical coverage (persons) in Nigeria was 38.3%. Coverage was 1.7 times higher among males than females. Coverage was only 9.1% among women in the South-South geopolitical zone. Over one third of those who were cataract blind said they could not afford surgery (36%). Cataract surgical coverage in Nigeria was among the lowest in the world. Urgent initiatives are necessary to improve surgical output and access to surgery.

Spinopelvic alignment is crucial in assessing an energy-efficient posture in both normal and disease states, such as high-displacement developmental spondylolisthesis (HDDS). The overall effect in patients with HDDS who have undergone local surgical correction of lumbosacral imbalance for the global correction of spinal balance remains unclear. This paper reports the progressive spontaneous improvement of global sagittal balance following surgical correction of lumbosacral imbalance in patients with HDDS. The records of 15 patients with HDDS who underwent surgery between 2005 and 2010 were reviewed. The treatment consisted of L4-sacrum reduction and fusion via a posterior approach, resulting in complete correction of lumbosacral kyphosis. Preoperative, 6-month postoperative, and final follow-up postoperative angular measurements were taken from full-spine lateral radiographs obtained with the patient in a standard standing position. Radiographic measurements included pelvic incidence, sacral slope, lumbar lordosis, and thoracic kyphosis. The degree of lumbosacral kyphosis was evaluated by the lumbosacral angle. Because of the small number of patients, nonparametric tests were considered for data analysis. Preoperative lumbosacral kyphosis and L-5 anterior slip were corrected by instrumentation. Transient neurological complications were noted in 5 patients. Statistical analysis showed a significant increase of thoracic kyphosis on 6-month postoperative and final follow-up radiographs (p < 0.001). A statistically significant decrease of lumbar lordosis was noted between preoperative and 6-month control radiographs (p < 0.001) and between preoperative and final follow-up radiographs (p < 0.001). Based on the authors' observations, this technique resulted in an effective reduction of L-5 anterior slip and significant reduction of lumbosacral kyphosis (from 69.8° to 105.13°). Due to complete reduction of lumbosacral kyphosis and anterior trunk displacement associated with L-5 anterior slipping, lumbar lordosis progressively decreased and thoracic kyphosis progressively increased postoperatively. Adjusting the sagittal trunk balance produced not only pelvic anteversion, but also reciprocal adjustment of lumbar lordosis and thoracic kyphosis, creating a satisfactory level of compensated global sagittal balance.

Midline dorsal plication is an efficient and safe surgical technique to correct chordee. We investigated the efficacy of midline dorsal plication for recurrent chordee in complicated hypospadias reoperations. We retrospectively evaluated the charts of 25 boys who underwent reoperation between 1999 and 2004 due to complications of primary hypospadias repair other than meatal stenosis. A total of 15 cases were initially managed elsewhere for primary repair or complications. The etiology of recurrent chordee was defined at surgical correction. When recurrent chordee was noted a midline dorsal plication was performed. Of 25 patients 10 had previously undergone chordee repair. Nine of these patients were observed to have recurrent chordee and 1 had de novo chordee. A total of 10 patients had recurrent or delayed onset chordee. Mean patient age at primary repair was 6.28 years (range 1 to 33). Mean age at last operation for chordee was 15.9 years (range 4 to 66). Mean interval to recurrent chordee was 6 years (range 1 to 16), excluding a 66-year-old blind patient who did not know when recurrent chordee developed. Five patients had chordee recur before puberty at a mean interval of 2.6 years. Mean reoperation rate was 2.4 for recurrent chordee cases and 2.6 for chordee-free cases. Mean followup after midline dorsal plication for recurrent chordee repair was 22 months (range 8 to 56), while mean followup in pubertal and postpubertal cases was 20 months. No recurrence of chordee or surgery related morbidity was observed after recurrent chordee repair by midline dorsal plication. Chordee may recur during puberty following successful chordee repair. The midline dorsal plication technique is simple, efficient and safe even in patients who have undergone multiple surgeries for hypospadias and chordee repair.

Traditionally, surgical intervention for patients with a spinal deformity has been considered for cosmetic benefits, but surgical intervention can alter the lung physiology or volumes and in turn leads to increase in physical capacity and exercise tolerance. Therefore, we conducted this to determine whether a surgical correction would restore the lung physiology, physical capacity and exercise tolerance in patients with kyphoscoliosis. To evaluate the usage of six-minute walk test scores and modified Borg scores as tools/measures for exercise tolerance in patients with spinal deformity and to study the effects of surgical correction of spinal deformity on exercise tolerance with above parameters as the measures. Thirty patients with spinal deformity, who had undergone surgery for deformity correction, were evaluated. All patients were investigated pre-operatively with x-rays of the spine (anteroposterior and lateral views). Clinical tests like breath holding time (after full inspiration) in number of seconds, modified Borg scores, six-minute walk test scores (heart rate, respiratory rate, maximum distance walked); were recorded as measures of exercise tolerance. The patients were followed up on the first, third, sixth and twelfth month post-operatively and tested clinically for breath holding time, modified Borg scores, six-minute walk test scores (heart rate, respiratory rate, maximum distance walked) and x-rays of the spine (anteroposterior and lateral views). In our study, breath holding time (p-value = 0.001) and modified Borg scores (p-value = 0.012) showed a significant improvement at 12 months post-operatively. We noted similar findings with heart rate, respiratory rate and maximum distance walked after a six-minute walk test. Improvements were noted in all the parameters, especially in the group of patients with greater than 60 degrees of cobb angle. However, the differences between the two groups (pre-operative cobb angle less than 60 degrees and pre-operative cobb angle more than 60 degrees) were not significant. The results were analysed and tested for significance using Student's t-test (paired and unpaired as appropriate) and Wilcoxon signed rank test. Surgical correction in cases of spinal deformity improves the cosmetic appearance and balance in the patients. Favourable results of surgical intervention were found in exercise tolerance with improvements in modified Borg scores, six-minute walk test results and breath holding time. The above parameters appear to be good tools for the assessment of physical capacity and exercise tolerance in patients with spinal deformity.

Late complication of open inguinal hernia repair: small bowel obstruction caused by intraperitoneal mesh migration.

We describe a case of small bowel obstruction due to prosthetic mesh migration. A 67-year-old male, who had undergone prosthetic repair of inguinal hernia 3 years before, was admitted for a mechanical small bowel obstruction. Laparotomy revealed the penultimate ileal loop choked by an adhesion drawing it towards a polypropylene mesh, firmly attached to the parietal peritoneum of the inguinal region. The intestinal loop was released; the mesh was embedded deep with continuous whip suture after folding the parietal peritoneum. The patient was dismissed on the 11th postoperative day surgically healed. The "tension-free" technique is undoubtedly the gold standard for hernia repair. However, it is not free of complications, mostly due to technical errors, of which the surgeon must be aware, both when he is responsible for correcting defects in the wall, as well as when he has to face an occlusion in a patient who has undergone plastic surgery for inguinal hernia.

To evaluate and compare refractive outcomes of moderate- and high-astigmatism correction after wavefront-guided laser in situ keratomileusis (LASIK) and small-incision lenticule extraction (SMILE). This comparative study enrolled a total of 64 eyes that had undergone SMILE (42 eyes) and wavefront-guided LASIK (22 eyes). Preoperative cylindrical diopters were ≤-2.25 D in moderate- and >-2.25 D in high-astigmatism subgroups. The refractive results were analyzed based on the Alpins vector method that included target-induced astigmatism, surgically induced astigmatism, difference vector, correction index, index of success, magnitude of error, angle of error, and flattening index. All subjects completed the 3-month follow-up. No significant differences were found in the target-induced astigmatism, surgically induced astigmatism, and difference vector between SMILE and wavefront-guided LASIK. However, the average angle of error value was -1.00 ± 3.16 after wavefront-guided LASIK and 1.22 ± 3.85 after SMILE with statistical significance (P < 0.05). The absolute angle of error value was statistically correlated with difference vector and index of success after both procedures. In the moderate-astigmatism group, correction index was 1.04 ± 0.15 after wavefront-guided LASIK and 0.88 ± 0.15 after SMILE (P < 0.05). However, in the high-astigmatism group, correction index was 0.87 ± 0.13 after wavefront-guided LASIK and 0.88 ± 0.12 after SMILE (P = 0.889). Both procedures showed preferable outcomes in the correction of moderate and high astigmatism. However, high astigmatism was undercorrected after both procedures. Axial error of astigmatic correction may be one of the potential factors for the undercorrection.

We describe an innovative single-stage reduction and stabilization technique using modern cervical instrumentation. We hypothesis modern instrumentation has made more aggressive surgical corrections possible and has reduced the need for transoral resection of the odontoid and traction reduction in children with basilar invagination. Craniocervical junction abnormalities, including atlantoaxial instability and progressive basilar invagination, are relatively common phenomenon in Down's syndrome patients, and can lead to chronic progressive neurologic deficits, catastrophic injury, and death. This patient population also can be a difficult one in which to perform successful stabilization and fusion. We reviewed the records and films on 2 children with Down's syndrome and atlantoaxial instability who had undergone prior occipital-cervical fusion and then presented with symptomatic progressive basilar invagination due to atlantoaxial displacement. In both cases, the children had progressive symptoms of spinal cord and brain stem compression. Multiple approaches for surgical correction, including preoperative traction and transoral odontoid resection, were considered, but ultimately it was elected to perform a single stage posterior operation. In both patients, we performed fusion takedown, intraoperative realignment with reduction of the basilar invagination, and stabilization using modern occipito-cervical instrumentation. In both children, excellent cranio-cervical realignment was achieved; along with successful fusion and improvement in clinical symptoms. In this article we will discuss the clinical cases and review the background of craniocervical junction abnormalities in Down's syndrome patients. We hypothesis modern instrumentation has made more aggressive surgical corrections possible and has reduced the need for transoral resection of the odontoid and traction reduction in children with basilar invagination.

PURPOSE This study aims to investigate the degree of subjective pain and the satisfaction of patients who have undergone an implant treatment using a computer-guided template. MATERIALS AND METHODS A survey was conducted for 135 patients who have undergone implant surgery with and without the use of the computer-guided template during the period of 2012 and 2013 in university hospitals, dental hospitals and dental clinics that practiced implant surgery using the computer-guided template. Likert scale and VAS score were used in the survey questions, and the independent t-test and One-Way ANOVA were performed (α=.05). RESULTS The route that the subjects were introduced to the computer-guided implant surgery using a surgical template was mostly advices by dentists, and the most common reason for which they chose to undergo such surgery was that it was accurate and safe. Most of them gave an answer that they were willing to recommend it to others. The patients who have undergone the computer-guided implant surgery felt less pain during the operation and showed higher satisfaction than those who have undergone conventional implant surgery. Among the patients who have undergone computer-guided implant surgery, those who also had prior experience of surgery without a computer-guided template expressed higher satisfaction with the former (P<.05). CONCLUSION In this study, it could be seen that the patients who have undergone computer-guided implant surgery employing a surgical template felt less pain and had higher satisfaction than those with the conventional one, and the dentist's description could provide the confidence about the safety of surgery.

Complications of Laparoscopy in Connection with Entry Techniques

PubMed Central

2017-01-01

Abstract The anatomy of the human being has not changed. However, technical developments in operating materials and methods call for improvements in surgical procedures as well as the management of complications. A fundamental distinction between any operating method and laparoscopy is that, in the latter, the initial entry is usually performed in blind fashion. Blind entry may result in vessel or organ damage, especially in patients who have undergone previous surgery. One of the difficulties associated with the entry is that the damage may not be identified immediately and then necessitate major abdominal repair. Furthermore, the improvement of surgical instruments and techniques enables the surgeon to perform even major operations by the laparoscopic approach. This is associated with renewed learning curves and a high rate of complications due to vascular, bowel, uterine, or bladder damage. The improvement of surgical techniques must be accompanied by advancements in the management of complications. The aim of this review is to address the risks of laparoscopy as well as their correct and professional management. (J GYNECOL SURG 33:81) PMID:28663686

Draining cutaneous sinus tract in chin area may be caused by chronic periapical dental infections. Misdiagnosis of these lesions usually leads to destructive invasive treatment of the sinus tract that is not correct and curative. A 31-year-old male patient referred to us with a chronically draining lesion on his chin. The lesion previously was misdiagnosed by medical doctors and had undergone two times surgery with a focus on the skin lesion and had received antibiotic therapy for a prolonged period of time. After clinical and radiologic examination the dental origin of the lesion was evident and proper endodontic and surgical treatment was performed. Three months later, after the treatment, the lesion showed total healing and reoccurrence occurred. The key to successful treatment of cutaneous sinus tract of dental origin must be in appropriate communication between the dentist and the physician in order to achieve correct diagnosis and therapy in such cases.

This paper reports on our progress using an erodible mask to perform photorefractive keratectomy (PRK) for the correction of myopic astigmatism. We describe modifications to the mask, the mask eye cup and the surgical microscope aimed at simplifying the procedure and improving the ergonomics of the hardware. We report the clinical results of the post-op exam for 20 patients who have undergone PRK for myopic astigmatism under a Phase IIA study. The results compare favorably with an earlier Phase IIA study for performing PRK with a computer-controlled iris. Most important, the clinical data show the absence of any significant corneal haze and no significant decrease in spectacle corrected visual acuity. Although more long term follow-up is needed, the preliminary results support the safety and effectiveness of using an erodible mask to perform PRK for myopic astigmatism.

Intra-Ocular Pressure Measurement in a Patient with a Thin, Thick or Abnormal Cornea.

2016-01-01

Accurate measurement of intra-ocular pressure is a fundamental component of the ocular examination. The most common method of measuring IOP is by Goldmann applanation tonometry, the accuracy of which is influenced by the thickness and biomechanical properties of the cornea. Algorithms devised to correct for corneal thickness to estimate IOP oversimplify the effects of corneal biomechanics. The viscous and elastic properties of the cornea influence IOP measurements in unpredictable ways, a finding borne out in studies of patients with inherently abnormal and surgically altered corneal biomechanics. Dynamic contour tonometry, rebound tonometry and the ocular response analyzer provide useful alternatives to GAT in patients with abnormal corneas, such as those who have undergone laser vision correction or keratoplasty. This article reviews the various methods of intra-ocular pressure measurement available to the clinician and the ways in which their utility is influenced by variations in corneal thickness and biomechanics.

Background: Lung transplantation is associated with a high incidence of gastroesophageal reflux disease (GERD). The presence of GERD is considered a risk factor for the subsequent development of obliterative bronchiolitis (OB), and surgical correction of GERD by gastric fundoplication (GF) may be associated with increased freedom from OB. The mechanisms underlying a protective effect from OB remain elusive. The objective of this study was to analyze the flow cytometric properties of BAL cells in patients who have undergone GF early after transplant. Methods: In a single-center lung transplant center, eight patients with GERD who were in the first transplant year underwent GF. Prior to and immediately following GF, BAL cells were analyzed by polychromatic flow cytometry. Spirometry was performed before and after GF. Results: GF was associated with a significant reduction in the frequency of BAL CD8 lymphocytes expressing the intracellular effector marker granzyme B, compared with the pre-GF levels. Twenty-six percent of CD8 cells were granzyme Bhi pre-GF compared with 12% of CD8 cells post-GF (range 8%-50% pre-GF, 2%-24% post-GF, P = .01). In contrast, GF was associated with a significant interval increase in the frequency of CD8 cells with an exhausted phenotype (granzyme Blo, CD127lo, PD1hi) from 12% of CD8 cells pre-GF to 24% post-GF (range 1.7%-24% pre-GF and 11%-47% post-GF, P = .05). No significant changes in spirometry were observed during the study interval. Conclusions: Surgical correction of GF is associated with a decreased frequency of potentially injurious effector CD8 cells in the BAL of lung transplant recipients. PMID:20522573

Long-term results of treatment of 180 patients operated 5 years ago for benign thyroid nodular pathology have been analyzed in the present paper, the results being analyzed depending on the volume of surgical intervention. The rate of postoperative hypothyrodism is lower in patients who had undergone limited thyroid resection, recurrent cases are more frequent, but they are not clinically significant and seldom require reoperation. It should also be noted that those patients have fewer cardiac complaints as the dose of hormone replacement therapy preparations is small. Elder patients who had undergone functionally significant thyroidectomy and need to take great doses of Thyroxin (107-150 mcg/day) have cardiac complaints more often (43 %) comparing to those who had undergone limited resections (35 %).

Summary Prophylactic mastectomy (PM) offers 90% or greater reduction in risk of breast cancer to women at increased hereditary risk. Nonetheless, acceptance in North America has been low (0–36%). Most women report reduced cancer worry post-operatively, but up to 25–50% of women electing surgery also report psychological distress and/or difficulty adapting following PM. Psychological consultation to aid decision-making and improve post-surgical coping isn’t routinely offered. This retrospective, cross-sectional study explored, quantitatively and qualitatively, interest in and acceptability of psychological consultation for issues related to PM among 108 women who had undergone or were considering surgery. Of the 71 women who had undergone PM, more than half felt pre-surgical psychological consultation was advisable and nearly 2/3 felt post-surgical psychological consultation would be helpful. All 37 women (100%) currently considering PM believed psychological consultation would aid decision-making and preparation for surgery. Narratives from the interviews illustrate the nature and intensity of the need for psychological support and describe preferences for the role of the psychologist. Suggestions are offered for the integration of psychological services for women deciding about or adapting to PM. PMID:18636423

To evaluate patients presenting with Tetralogy of Fallot with absent pulmonary valve syndrome to a tertiary care hospital and their surgical management. The retrospective study was conducted at Congenital Cardiac Services, Aga Khan University Hospital, Karachi, Pakistan, and comprised data of Tetralogy of Fallot patients between April 2007 and June 2012. Data was analysed together with follow-up echocardiography. Variables assessed included demographics, imaging, operative technique, complications, post-operative recovery and follow-up echocardiography. SPSS 17 was used for statistical analysis. Of the 204 patients, 6 (3%) had undergone surgical correction for Tetralogy of Fallot with absent pulmonary valve syndrome. All 6(100%) patients underwent complete repair. Median age for surgery was 8.5 years (range: 0.5-29 years). Of the different surgical strategies used, Contegra and Bioprosthetic valve placement had satisfactory outcome with minimal gradient at Right Ventricular Outflow Tract, good ventricular function and mild valvular regurgitation. One (16.6%) patient with Trans Annular Patch developed post-operative Right Ventricle Outflow Tract gradient of 80mmHg with moderate pulmonary regurgitation. One (16.6%) patient with monocusp valve developed free pulmonary regurgitation at 6 months. The other 4(66.6%) patients are currently free from any complications or re-intervention. Early surgery is preferred in symptomatic patients. The repair depends upon achieving integrity of pulmonary circulation which is best achieved by using right ventricle to pulmonary artery conduit or inserting a pulmonary valve.

A sufficient decline in levels of parathyroid hormone measured intraoperatively (ioPTH) precludes early and late surgical failures. A case series of consecutive patients undergoing parathyroidectomy with ioPTH measurement. A university hospital. Two hundred sixty-nine consecutive patients with sporadic primary hyperparathyroidism who underwent first-time parathyroid surgery with ioPTH measurement were followed up for as long as 10 years after surgery. Data on all patients have been collected in a prospective database. Surgical failures up to 10 years after parathyroid surgery. With an average follow-up of 3.6 years (range, 6-120 months), the overall cure rate was 96%. The ioPTH level correctly predicted long-term outcome in 248 (92%) of 269 patients. Six patients had a false-positive ioPTH finding. Five of these patients were found to have germline mutations in the gene for multiple endocrine neoplasia. The remaining patient has not undergone genetic testing. The mutations have rarely (n = 1) or never (n = 4) been described before, to our knowledge. Intraoperative measurement of PTH level has a high overall accuracy with a mean follow-up of 3.6 years. However, among the late surgical failures with false-positive ioPTH findings, overlooked mutations in the multiple endocrine neoplasia gene should be suspected, and therefore genetic analyses in these patients are of great importance.

With the rapid development of vision correction techniques, increasing numbers of people have undergone laser vision corrective surgery in recent years. The use of a laser scalpel instead of a traditional surgical knife reduces the size of the wound and quickens recovery after surgery. The primary objective of this article is to examine corneal surgery for vision correction via multi-layer swim-ring-shaped wave circles of the technique through optical simulations with the use of Monte-Carlo ray tracing method. Presbyopia stems from the loss of flexibility of crystalline lens due to aging of the eyeball. Diopter adjustment of a normal crystalline lens could reach 5 D; in the case of presbyopia, the adjustment was approximately 1 D, which made patients unable to see objects clearly in near distance. Corneal laser surgery with multi-layer swim-ring-shaped wave circles was performed, which ablated multiple circles on the cornea to improve flexibility of the crystalline lens. Simulation results showed that the ability of the crystalline lens to adjust increased tremendously from 1 D to 4 D. The method was also used to compare the images displayed on the retina before and after the treatment. The results clearly indicated a significant improvement in presbyopia symptoms with the use of this technique.

Purpose To describe the relationship between binocular summation and stereoacuity after strabismus surgery. Design Prospective Case Series Methods Setting Stein Eye institute, University of California Los Angeles Patient Population Pediatric strabismic patients who underwent strabismus surgery between 2010 and 2015. Observation Procedures Early Treatment Diabetic Retinopathy Study visual acuity, Sloan low-contrast acuity (LCA, 2.5% and 1.25%) and Randot stereoacuity 2 months following surgical correction of strabismus. Main Outcome Measures The relationship between binocular summation, calculated as the difference between the binocular visual acuity score and that of the better eye, and stereoacuity. Results A total of 130 post-operative strabismic patients were studied. The relationship between binocular summation and stereoacuity was studied by Spearman correlation. There were significant correlations between BiS for 2.5% LCA with near and distance stereoacuity (p=0.006 and 0.009). BiS for 1.25% LCA was also significantly correlated with near stereoacuity (p=0.04). Near stereoacuity and BiS for 2.5% and 1.25% LCA were significantly dependent (Pearson Chi Squared, p=0.006 and p=0.026). Patients with stereoacuity demonstrated significantly more BiS in 2.5% LCA of 2.7 (p=0.022) and 3.1 (p=0.014) letters than did those without near or distance stereoacuity, respectively. Conclusions These findings demonstrate that stereopsis and binocular summation are significantly correlated in patients who have undergone surgical correction of strabismus. PMID:26921805

Our purpose was to assess the feasibility of orthotopic liver transplantation (OLT) in patients priorly having undergone transjugular intrahepatic portosystemic shunt (TIPS) with an expanded tetrafluoroethylene (e-PTFE)-covered endoprosthesis. In 48 patients an e- PTFE-covered endoprosthesis was inserted to treat severe complications of portal hypertension. In 36 patients the endoprosthesis was inserted during TIPS creation (de novo TIPS); in the other 12 patients the endoprosthesis was placed to repermeabilize the previously created, but occluded bare stent (revision TIPS). Eight of them (5 de novo and 3 revision cases) later underwent an OLT. The hospital records of these patients were reviewed frommore » initial admission, through TIPS, the pre-OLT period, and OLT to current postoperative status. Five de novo and 3 revision cases underwent OLT 4-279 days (mean delay: 80.8 days) after TIPS procedure. All OLT's were performed under veno-venous bypass surgery. De visu surgical inspection confirmed correct positioning of the fully patent stent graft, starting in the portal vein and ending at the junction of the hepatic vein to the inferior caval vein. No surgical difficulty was observed during proximal or distal clamping or during resection of the diseased liver. Correctly positioned e-PTFE-covered nitinol endoprostheses do not interfere with a later OLT and may not be considered as a contraindication in patients who need a TIPS as a bridge to OLT.« less

Diagnostic molecular testing is used in the workup of thyroid nodules. While these tests appear to be promising in more definitively assigning a risk of malignancy, their effect on surgical decision making has yet to be demonstrated. To investigate the effect of diagnostic molecular profiling of thyroid nodules on the surgical decision-making process. A surgical management algorithm was developed and published after peer review that incorporated individual Bethesda System for Reporting Thyroid Cytopathology classifications with clinical, laboratory, and radiological results. This algorithm was created to formalize the decision-making process selected herein in managing patients with thyroid nodules. Between April 1, 2014, and March 31, 2015, a prospective study of patients who had undergone diagnostic molecular testing of a thyroid nodule before being seen for surgical consultation was performed. The recommended management undertaken by the surgeon was then prospectively compared with the corresponding one in the algorithm. Patients with thyroid nodules who did not undergo molecular testing and were seen for surgical consultation during the same period served as a control group. All pertinent treatment options were presented to each patient, and any deviation from the algorithm was recorded prospectively. To evaluate the appropriateness of any change (deviation) in management, the surgical histopathology diagnosis was correlated with the surgery performed. The study cohort comprised 140 patients who underwent molecular testing. Their mean (SD) age was 50.3 (14.6) years, and 75.0% (105 of 140) were female. Over a 1-year period, 20.3% (140 of 688) had undergone diagnostic molecular testing before surgical consultation, and 79.7% (548 of 688) had not undergone molecular testing. The surgical management deviated from the treatment algorithm in 12.9% (18 of 140) with molecular testing and in 10.2% (56 of 548) without molecular testing (P = .37). In the group with molecular testing, the surgical management plan of only 7.9% (11 of 140) was altered as a result of the molecular test. All but 1 of those patients were found to be overtreated relative to the surgical histopathology analysis. Molecular testing did not significantly affect the surgical decision-making process in this study. Among patients whose treatment was altered based on these markers, there was evidence of overtreatment.

Controversies remain regarding the proper diagnostic studies and prediction of outcome in patients with normal pressure hydrocephalus (NPH), and their management remains controversial. We propose a preoperative assessment routine the aim of which is to correctly select NPH patients, and to differentiate between them in terms of surgical treatment, identifying probable endoscopic third ventriculostomy (ETV) responders. We prospectively considered a group of 44 patients with suspected NPH on the basis of clinical symptoms and neuroradiological evidence, who have undergone supplemental diagnostic testing (tap test, external lumbar drainage, cerebrospinal fluid outflow resistance [Rout] determination through lumbar and ventricular infusion test). All 44 of these patients were treated with either shunt procedures or ETV. To choose the kind of treatment (shunt or ETV), we evaluated the individual response during infusion tests. The efficacy of both surgical techniques was approximately 70%, with a significantly lower complication rate for ETV. We evaluated the correlation between the various tests and the postoperative outcomes both for shunting and for ETV. Rout proved useful for preoperative assessment and choice of treatment. In carefully selected patients, ETV had qualitative results similar to shunting, presenting significantly fewer complications.

The main focus of this study was to evaluate how preoperative simulation affects the surgical work flow, radiation exposure, and outcome of minimally invasive hybrid lumbar interbody fusion (MIS-HLIF). A total of 132 patients who underwent single-level MIS-HLIF were enrolled in a cohort study design. Dose area product was analyzed in addition to surgical data. Once preoperative simulation was established, 66 cases (SIM cohort) were compared with 66 patients who had previously undergone MIS-HLIF without preoperative simulation (NO-SIM cohort). Dose area product was reduced considerably in the SIM cohort (320 cGy·cm 2 NO-SIM cohort: 470 cGy·cm 2 ; P < 0.01). Surgical time was shorter for the SIM cohort (155 minutes; NO-SIM cohort, 182 minutes; P < 0.05). SIM cohort had a better outcome in Numeric Rating Scale back at 6 months follow-up compared with the NO-SIM cohort (P < 0.05). Preoperative simulation reduced radiation exposure and resulted in less back pain at the 6 months follow-up time point. Preoperative simulation provided guidance in determining the correct cage height. Outcome controls enabled the surgeon to improve the procedure and the software algorithm.

Our objective was to report the orthodontic and surgical retreatment of a patient who had undergone a prolonged orthodontic treatment with extractions, but who had unsatisfactory results and persistent side effects. The man, aged 25 years 3 months, sought treatment with major complaints of facial and smile asymmetries. The clinical examination showed a mandibular deviation to the right and a maxillary occlusal cant. A Class II Division 1 subdivision right was observed. Radiographic examination showed extensive root resorptions in the maxillary second premolars and absence of the 4 first premolars. The maxillary midline was deflected 2 mm to the left, and the mandibular midline was shifted 5 mm to the right. Aligning and leveling were performed with orthodontic fixed appliances, with a standard edgewise system (0.022 × 0.028 in), followed by LeFort I maxillary impaction and bilateral sagittal split osteotomy with asymmetrical advancement. Retreatment showed outstanding results that remained stable after 3 years of follow-up. Root resorption in the second premolars did not seem to increase. Orthodontic-surgical intervention is the main choice for correcting esthetic and functional problems in facial asymmetry, particularly in cases of retreatment.

The following study was a prospective radiographic and retrospective clinical data assessment of adolescent idiopathic scoliosis (AIS) patients who had undergone a key-vertebral screws strategy (KVSS) at a single institution, with a minimum of 2 years' follow-up. The aim of the study was to introduce the KVSS for the operative treatment of AIS of the main thoracic curve, and to address the role of the fulcrum-bending radiograph (FBR) in predicting the outcome of surgical management by this method. The application of multilevel pedicle screws for the main thoracic curve in AIS patients is popular in an effort to provide spinal stability, enhance fusion outcome, and provide optimal curve correction. However, with the application of pedicle screw also comes a potential risk for soft tissue and neural injury and increased health care costs. It remains unknown whether limited screw placement can provide proper curve correction without compromising patient outcome. A total of 17 consecutive patients with AIS extending to the main thoracic spine, who had undergone posterior fusion and fixation by the KVSS, a procedure in which screws are placed at important strategic points in the spine (ie, bilaterally at the upper and lower end segments of the fusion block, apical vertebra on the convex side, adjacent cephalad, and caudal screw placement on the concave side), at a single institution, with a minimum of 2 year' follow-up, were included. The assessment of preoperative standing posteroanterior and sagittal, FBR, and postoperative standing posteroanterior and sagittal plain radiographs were assessed in all patients. The flexibility of the curve as well as the fulcrum-bending correction index (FBCI) were calculated for all patients. Postoperatively, radiographs were assessed at the immediate (ie, 1 wk) and last follow-up. Clinical assessment entailed evaluation of patient demographics and the presence of any intraoperative or postoperative complications. The mean age at the time of surgery was 15.6 years. The mean follow-up was 39.8 months. The average FBR flexibility was 62.2%. The mean immediate curve correction was 71.2%, which did not differ in comparison with the last follow-up assessment (P>0.05). The mean immediate and last follow-up FBCIs were 119.3% and 112.5%, respectively (P=0.079). A significant negative correlation was found between immediate FBCI to that of the FBR curve flexibility (r=-0.706; P=0.002), which remained similar on the last follow-up (r=-0.681; P=0.003). Sagittal alignment did not significantly change from the immediate to last follow-up (P=0.163) Fusion was achieved in all patients. No instrumentation-related complications were noted. Key-vertebral screws strategy is a safe and cost-effective method for the surgical treatment of the main thoracic curve in AIS patients. Moreover, in the context of this strategy, the FBR may have some predictive utility in the correction of the main thoracic curve in AIS patients.

Comorbidities have considerable effects on survival outcomes. The primary objective of this retrospective study was to examine the association between age-adjusted Charlson comorbidity index (ACCI) score and postoperative in-hospital mortality in patients with digestive system cancer who have undergone surgical resection of their cancers. Using electronic hospitalization summary reports, we identified 315,464 patients who had undergone surgery for digestive system cancer in top-rank (Grade 3A) hospitals in China between 2013 and 2015. The Cox proportional hazard regression model was applied to evaluate the effect of ACCI score on postoperative mortality, with adjustments for sex, type of resection, anesthesia methods, and caseload of each healthcare institution. The postoperative in-hospital mortality rate in the study cohort was 1.2% (3,631/315,464). ACCI score had a positive graded association with the risk of postoperative in-hospital mortality for all cancer subtypes. The adjusted HRs for postoperative in-hospital mortality scores ≥ 6 for esophagus, stomach, colorectum, pancreas, and liver and gallbladder cancer were 2.05 (95% CI: 1.45-2.92), 2.00 (95% CI: 1.60-2.49), 2.54 (95% CI: 2.02-3.21), 2.58 (95% CI: 1.68-3.97), and 4.57 (95% CI: 3.37-6.20), respectively, compared to scores of 0-1. These findings suggested that a high ACCI score is an independent predictor of postoperative in-hospital mortality in Chinese patients with digestive system cancer who have undergone surgical resection.

To report the outcome of scleral buckling using a non-contact wide-angle viewing system with a 25-gauge chandelier endoilluminator. Retrospective analyses of medical records were performed for 17 eyes of 16 patients with primary rhegmatogenous retinal detachment (RRD) without proliferative vitreoretinopathy who had undergone conventional scleral buckling with cryoretinopexy using the combination of a non-contact wide-angle viewing system and chandelier endoillumination. The patients were eight males and five females with a mean age of 26.8 ± 10.2 (range, 11 to 47) years. The mean follow-up period was 7.3 ± 3.1 months. Baseline best-corrected visual acuity was 0.23 ± 0.28 logarithm of the minimum angle of resolution units. Best-corrected visual acuity at the final visit showed improvement (0.20 ± 0.25 logarithm of the minimum angle of resolution units), but the improvement was not statistically significant (p = 0.722). As a surgery-related complication, there was vitreous loss at the end of surgery in one eye. As a postoperative complication, increased intraocular pressure (four cases) and herpes simplex epithelial keratitis (one case) were controlled postoperatively with eye drops. One case of persistent RRD after primary surgery needed additional vitrectomy, and the retina was postoperatively attached. Scleral buckling with chandelier illumination as a surgical technique for RRD has the advantages of relieving the surgeon's neck pain from prolonged use of the indirect ophthalmoscope and sharing the surgical procedure with another surgical team member. In addition, fine retinal breaks that are hard to identify using an indirect ophthalmoscope can be easily found under the microscope by direct endoillumination. © 2017 The Korean Ophthalmological Society

Inferior sinus venosus defects: anatomic features and echocardiographic correlates.

Inferior sinus venosus defects (SVDs) are rare imperfections located in the inferior portion of the atrial septum, leading to an overriding inferior vena cava (IVC) and an interatrial connection. These defects have increased risk of anomalous pulmonary venous return (PAPVR) and often are confused with secundum atrial septal defects (ASDs) with inferior extension. The authors sought to review their experience with inferior SVDs and to establish at their institution an echocardiographic definition that differentiates inferior SVDs from secundum ASDs with inferior extension. The study identified 161 patients 1.5 to 32 years of age who had undergone repair of a secundum ASD with inferior extension or inferior SVD over the preceding 10 years. All surgical notes, preoperative transthoracic echocardiograms (TTEs), and preoperative transesophageal echocardiograms (TEEs) were reviewed. Based on the surgical notes, 147 patients were classified as having a secundum ASD (147/161, 91 %) and 14 patients (9 %) as having an inferior SVD. The study identified PAPVR in 7 % (1/14) of the patients with inferior SVDs and 3.5 % (5/14) of the patients with secundum ASDs. Surgical diagnosis and preoperative TTE correlated for 143 (89 %) of the 161 patients. Using a strict anatomic and echocardiographic definition with a blinded observer, the majority of the defects (14/18, 78 %) were reclassified correctly after review of their TTE images, and 100 % of the defects were correctly reclassified after TEE image review. Accurate diagnosis of inferior SVDs remains challenging. The data from this study demonstrate that use of a strict anatomic and echocardiographic definition (a defect that originates in the mouth of the IVC and continues into the inferoposterior border of the left atrium, leaving no residual atrial septal tissue at the inferior margin) allows for accurate differentiation between secundum ASDs with inferior extension and inferior SVDs. This differentiation is extremely important in planning for surgical versus device closure of these rare defects.

We evaluated whether intraoperative real-time TRUS navigation during LRP can decrease the incidence of positive surgical margins. Since March 2001, 294 patients with clinically organ confined prostate cancer undergoing LRP have been retrospectively divided into 2 groups, including group 1-217 who underwent LRP without TRUS from March 2001 to February 2003 and group 2-77 who have undergone LRP with TRUS since March 2003. Various baseline parameters were similar between the groups. Before March 2001 the senior surgeon had already performed more than 50 cases of LRP, thus, gaining reasonable familiarity with the technique. Compared to group 1, group 2 had a significantly decreased rate of positive surgical margins in patients with pT3 disease (57% vs 18%, p = 0.002). Positive margin rates also decreased in our overall experience (29% vs 9%, p = 0.0002). Intraoperative TRUS correctly predicted pT2 and pT3 disease in 85% and 86% of patients, respectively. Of the 54 TRUS visualized hypoechoic lesions at sites corresponding to biopsy proven cancer extracapsular extension was suspected in 31, leading to a real-time recommendation of calibrated wider, site specific dissection to achieve negative surgical margins. Intraoperative TRUS monitoring during LRP allows individualized, precise dissection tailored to the specific prostate contour anatomy, thus, compensating for the muted tactile feedback of laparoscopy. In what is to our knowledge the initial experience real-time TRUS guidance significantly decreased the incidence of positive surgical margins during LRP. In the future this concept of rectum based, intraoperative real-time navigation may facilitate a more sophisticated performance of radical prostatectomy.

Antifibrinolytics such as tranexamic acid reduce operative blood loss and blood product transfusion requirements in patients undergoing surgical correction of scoliosis. The factors involved in the unrelenting coagulopathy seen in scoliosis surgery are not well understood. One potential contributor is activation of the fibrinolytic system during a surgical procedure, likely related to clot dissolution and consumption of fibrinogen. The addition of tranexamic acid during a surgical procedure may mitigate the coagulopathy by impeding the derangement in D-dimer and fibrinogen kinetics. We retrospectively studied consecutive patients who had undergone surgical correction of adult spinal deformity between January 2010 and July 2016 at our institution. Intraoperative hemostatic data, surgical time, estimated blood loss, and transfusion records were analyzed for patients before and after the addition of tranexamic acid to our protocol. Each patient who received tranexamic acid and met inclusion criteria was cohort-matched with a patient who underwent a surgical procedure without tranexamic acid administration. There were 17 patients in the tranexamic acid cohort, with a mean age of 60.7 years, and 17 patients in the control cohort, with a mean age of 60.9 years. Estimated blood loss (932 ± 539 mL compared with 1,800 ± 1,029 mL; p = 0.005) and packed red blood-cell transfusions (1.5 ± 1.6 units compared with 4.0 ± 2.1 units; p = 0.001) were significantly lower in the tranexamic acid cohort. In all single-stage surgical procedures that met inclusion criteria, the rise of D-dimer was attenuated from 8.3 ± 5.0 μg/mL in the control cohort to 3.3 ± 3.2 μg/mL for the tranexamic acid cohort (p < 0.001). The consumption of fibrinogen was 98.4 ± 42.6 mg/dL in the control cohort but was reduced in the tranexamic acid cohort to 60.6 ± 35.1 mg/dL (p = 0.004). In patients undergoing spinal surgery, intravenous administration of tranexamic acid is effective at reducing intraoperative blood loss. Monitoring of D-dimer and fibrinogen during spinal surgery suggests that tranexamic acid impedes the fibrinolytic pathway by decreasing consumption of fibrinogen and clot dissolution as evidenced by the reduced formation of D-dimer.

To evaluate 3-dimensional (3-D) photogrammetry as a tool for assessing the postoperative head shape of patients who had undergone cranial vault remodeling for metopic synostosis. We prospectively analyzed images of patients with metopic craniosynostosis who had undergone anterior cranial vault remodeling and age-matched controls. To ensure standardized facial orientation, each 3-D image was positioned to "best fit" the preoperative face by aligning 6 soft tissue landmarks. Forehead measurements were taken from a standardized position behind the surface of the face to landmarks placed in a ray configuration across the forehead. Academic teaching hospital. Thirteen pediatric patients with metopic craniosynostosis who had undergone anterior cranial vault remodeling and age-matched controls. Images were taken preoperatively, immediately postoperatively, and over 1-year postoperatively. Forehead contours preoperatively and postoperatively, with statistics performed using a multivariate analysis of variance shape analysis. Mean postoperative follow-up was 1.8 (0.6) years. The average distance from the origin to forehead landmarks was 55.1 (3.4) mm preoperatively, 59.3 (0.7) mm immediate postoperatively, 59.1 (1.0) mm 1-year postoperatively, and 59.4 (0.6) mm in controls. Postoperative metopic forehead contours varied significantly from preoperative contours ( P < .01), while there was no statistical difference between the 2 postoperative time points ( P = .70). One-year postoperative patients were not significantly different from their age-matched controls ( P > .99). Preoperative metopic forehead contours varied significantly from postoperative contours. Cranial reconstructions approximated the foreheads of normal controls, and reconstructions were stable at more than 1-year follow-up.

Up to 77% of Down syndrome (DS) patients have associated structural or functional gastrointestinal abnormalities. Functional disturbances, such as processes affecting the enteric nervous system, can often affect the outcome of corrective surgical procedures. Recently, an association between DS and achalasia has been reported. In this report we present a 28-year-old male patient with a history of Down syndrome and achalasia, who presented with recurrent dysphagia, gastroesophageal reflux, and recurrent aspirations. The patient had previously undergone a laparoscopic Heller myotomy with Dor fundoplication. Unfortunately, despite this surgery, he continued to require multiple esophageal dilations, and intraesophageal administration of Botox therapy. Additionally, there were numerous subsequent hospital admissions for recurrent aspiration pneumonia. Evaluation revealed an incomplete myotomy and a revision long Heller myotomy was successfully performed intraabdominally and he is now symptom and aspiration free.

Crohns disease (CD) belongs to chronic diseases that highly affect the patient´s quality of life (QoL). The effect of the disease and impairment of QoL in CD patients is already known. The aim was to assess how surgical treatment influences the patients QoL and determine factors that can affect postoperative QoL. We compared the QoL before and after surgery in patients who had undergone a bowel resection at our department due to CD between 2010-2016. The patients filled in a standardized QLQ-CR29 questionnaire to assess QoL in the preoperative period and the postoperative period after a 2-month interval. The control groups were CD patients who had not undergone surgical treatment (bowel resection) and a healthy cohort. In the QoL evaluation, 132 patients with CD who had undergone surgery (bowel resection), 83 patients with CD without an operation and 104 healthy subjects were enrolled. 104 of the operated patients experienced a postoperative improvement of the overall QoL (78.8 %), 2 patients did not register any changes in QoL (1.5 %) and 26 patients (19.7 %) experienced a worsening of their postoperative QoL. The results were statistically significant (p < 0.001). We detected a significant improvement of the overall QoL after surgical resection in CD patients (measured 2 months after surgery). Gender was identified as the only statistically relevant factor with influence on postoperative QoL.Key words: bowel resection - Crohn´s disease - Czech cohort - inflammatory bowel disease - quality of life - surgical treatment.

Although the efficacy of Akin proximal phalanx closing wedge osteotomy as a sole procedure for correction of hallux valgus deformity is questionable, when used in combination with other osseous corrective procedures, the procedure has been believed to be efficacious. However, a limited number of comparative studies have confirmed the value of this additional procedure. We identified patients who had undergone osseous hallux valgus correction with first metatarsal osteotomy or first tarsometatarsal joint arthrodesis with (n = 73) and without (n = 81) Akin osteotomy and evaluated their radiographic measurements at 3 points (preoperatively, within 3 months after surgery, and ≥6 months after surgery). We found that those people who had undergone the Akin procedure tended to have a larger hallux abduction angle and a more laterally deviated tibial sesamoid position preoperatively. Although the radiographic correction of the deformity was promising immediately after corrective surgery with the Akin osteotomy, maintenance of the correction was questionable in our cohort. The value of additional Akin osteotomy for correction of hallux valgus deformity is uncertain. Published by Elsevier Inc.

Clinical study with pre- and postoperative back photographs and postoperative Scoliosis Research Society-22 survey in patients who had undergone surgery for idiopathic scoliosis. To determine the effect of showing patients their photographs before and after surgery for idiopathic scoliosis on postoperative patient satisfaction. After scoliosis surgery, patient satisfaction may be limited because the patients cannot directly see their back and may forget the preoperative appearance. In 60 patients who had undergone surgery for correction of idiopathic scoliosis (Lenke type 1), pre- and postoperative photographs were taken from the anterior, posterior, and right and left lateral views. After surgery, patients in group 1 (30 patients) were shown the preoperative and most recent follow-up photographs, and patients in group 2 (30 patients) had routine evaluation but were not shown their photographs. All patients completed the Scoliosis Research Society-22 survey. Patients in both groups had similar age, sex, distribution of Lenke type and Risser sign, follow-up, and pre- and postoperative Cobb angles and balance (coronal and sagittal). A significant difference was observed between the groups for survey question 10 (which was about self-image), question 18 (which was about function and activity), and question 21 (which was about satisfaction) (P ≤ 0.05). There were no differences between patients in groups 1 and 2 in Scoliosis Research Society-22 domain or total scores. By showing patients the pre- and postoperative clinical photographs, patient satisfaction may be greater, as measured with some SRS-22 scores. This method may enable clinicians to positively change the patients' self-image perception after surgery for correction of scoliosis. 4.

The effects of breast cancer surgical treatment on the professional singing voice are unknown. The purpose of this study was to discover whether there are self-perceived changes in the quality and/or process of singing experienced by professional female singers who have undergone surgical intervention for the treatment of diagnosed breast cancer-including any changes perceived from the use of radiation, chemotherapy, and other drug treatments related to those surgeries. A voluntary subject pool comprised female professional singers who have undergone surgery for breast cancer was recruited from professional singing networks. Participants underwent evaluation through an anonymous online survey, psychometrically vetted for content and instrument reliability/validity before administration. Valid participants (N=56) responded to 45 questions regarding surgical procedures, related therapies, and self-perceived vocal effects. Analysis of results produced a preliminary description of types of voice change, duration of changes, and qualitative self-perceptions. This initial report reveals that there are self-perceived singing voice changes experienced by professional singers treated for breast cancer. However, additional research is needed to determine the degree of vocal impact perceived to be attributable to individual surgical interventions and related therapies.

To report anatomic and visual outcomes following silicone oil removal in a cohort of patients with complex retinal detachment, to determine association between duration of tamponade and outcomes and to compare patients with oil removed and those with oil in situ in terms of demographic, surgical and visual factors. We reported a four years retrospective case series of 143 patients with complex retinal detachments who underwent intraocular silicone oil tamponade. Analysis between anatomic and visual outcomes, baseline demographics, duration of tamponade and number of surgical procedures were carried out using Fisher's exact test and unpaired two-tailed t -test. One hundred and six patients (76.2%) had undergone silicone oil removal at the time of review with 96 patients (90.6%) showing retinal reattachment following oil removal. Duration of tamponade was not associated with final reattachment rate or with a deterioration in best corrected visual acuity (BCVA). Patients with oil removed had a significantly better baseline and final BCVA compared to those under oil tamponade ( P =0.0001, <0.0001 respectively). Anatomic and visual outcomes in this cohort are in keeping with those reported in the literature. Favorable outcomes were seen with oil removal but duration of oil tamponade does not affect final attachment rate with modern surgical techniques and should be managed on a case by case basis.

Overall, 136 patients including 60 (44.1%) male and 76 (55.9%) female subjects with a mean age of 20 ± 13.8 years (range, 2 to 80 years) were evaluated, of whom 120 cases (88.2%) had congenital ptosis and the rest had acquired ptosis. The overall success rate after the first operation was 78.7%. The most common complication after the first operation was undercorrection in 26 cases (19.1%), which was more prevalent among young patients (p = 0.06). Lid fissure and margin reflex distance (MRD(1)) also increased after levator resection (p < 0.001). Age, sex, type of ptosis, amblyopia, levator function, MRD(1), lid fissure and spherical equivalent were not predictive of surgical outcomes of levator resection. Levator resection has a high rate of success and few complications in the surgical treatment of congenital and acquired upper lid ptosis with fair to good levator function. Reoperation can be effective in most cases in which levator resection has been performed.

The aim was to describe the clinical presentation and the surgical management of penile epispadias associated with a buried penis in five children. This is a 5-year retrospective review of patients presenting with a buried penis, a congenital defect of the penile skin shaft associated with an unretractable foreskin for whom a penile epispadias was found at the time of surgery. All had undergone surgery combining a Cantwell-Ransley procedure and refashioning of the penile skin following the authors' technique. Three children had a glanular epispadias and two had a midshaft epispadias. Four had a satisfactory outcome, and one required a complementary urethroplasty for glanular dehiscence. Buried penis and epispadias are usually isolated congenital anomalies, although they can be associated. It is therefore recommended to warn parents about the possibility of underlying penile anomaly in children with buried penises and unretractable foreskin. Careful palpation of the dorsum of the glans through the foreskin looking for a dorsal cleft could indicate an associated epispadiac urethra. Surgical correction of both anomalies can be done at the same time. Parents of boys with buried penises should be warned that underlying penile anomaly may exist.

Cedars, Ari M.

2015-01-01

Transposition of the great arteries encompasses a set of structural congenital cardiac lesions that has in common ventriculoarterial discordance. Primarily because of advances in medical and surgical care, an increasing number of children born with this anomaly are surviving into adulthood. Depending upon the subtype of lesion or the particular corrective surgery that the patient might have undergone, this group of adult congenital heart disease patients constitutes a relatively new population with unique medical sequelae. Among the more common and difficult to manage are cardiac arrhythmias and other sequelae that can lead to sudden cardiac death. To date, the question of whether implantable cardioverter-defibrillators should be placed in this cohort as a preventive measure to abort sudden death has largely gone unanswered. Therefore, we review the available literature surrounding this issue. PMID:26413012

Cardiac Embryology and Molecular Mechanisms of Congenital Heart Disease: A Primer for Anesthesiologists.

PubMed

Kloesel, Benjamin; DiNardo, James A; Body, Simon C

2016-09-01

Congenital heart disease is diagnosed in 0.4% to 5% of live births and presents unique challenges to the pediatric anesthesiologist. Furthermore, advances in surgical management have led to improved survival of those patients, and many adult anesthesiologists now frequently take care of adolescents and adults who have previously undergone surgery to correct or palliate congenital heart lesions. Knowledge of abnormal heart development on the molecular and genetic level extends and improves the anesthesiologist's understanding of congenital heart disease. In this article, we aim to review current knowledge pertaining to genetic alterations and their cellular effects that are involved in the formation of congenital heart defects. Given that congenital heart disease can currently only occasionally be traced to a single genetic mutation, we highlight some of the difficulties that researchers face when trying to identify specific steps in the pathogenetic development of heart lesions.

Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. Physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.

Surgical training has undergone many changes in the last decade. One outcome of these changes is the interest that has been generated in the possibility of training surgical skills outside the operating theatre. Simulation of surgical procedures and human tissue, if perfect, would allow complete transfer of techniques learnt in a skills laboratory directly to the operating theatre. Several techniques of simulation are available including artificial tissues, animal models and virtual reality computer simulation. Each is discussed in this article and their advantages and disadvantages considered. Images Figure 1 Figure 2 Figure 3 Figure 4 PMID:10743423

Secondary pancreaticoduodenectomy was performed in 2 patients, 1 who had undergone proximal gastrectomy for a gastric carcinoma and 1 who had undergone subtotal esophagectomy with stomach tube reconstruction for an inferior thoracic esophageal carcinoma. To prevent ischemia and congestion of the remnant stomach, the inflow and outflow pathways to the stomach, such as the right gastroepiploic artery and vein, were preserved. In this article, we describe the preservation procedures and discuss the problems of the secondary abdominal surgical procedure.

Achilles Tendon Open Surgical Treatment With Platelet-Rich Fibrin Matrix Augmentation: Biomechanical Evaluation.

Alviti, Federica; Gurzì, Michele; Santilli, Valter; Paoloni, Marco; Padua, Roberto; Bernetti, Andrea; Bernardi, Marco; Mangone, Massimiliano

The relationship between surgical technique and ankle biomechanical properties after surgery for acute rupture of the Achilles tendon (ATR) has not yet been fully investigated. Platelet-rich fibrin (PRF) matrices seem to play a central role in the complex processes of tendon healing. Our aim was to analyze the biomechanical characteristics, stiffness, and mechanical work of the ankle during walking in patients who had undergone surgery after ATR with and without PRF augmentation. We performed a retrospective review of all consecutive patients who had been treated with surgical repair after ATR. Of the 20 male subjects enrolled, 9 (45%) had undergone conventional open repair of the Achilles tendon using the Krackow technique (no-PRF) and 11 (55%) had undergone surgery with PRF augmentation. An additional 8 healthy subjects were included as a control group. A gait analysis evaluation was performed at 6 months after surgery. The percentage of the stance time of the operated leg, double-support time of the healthy leg, and net work of the ankle during the gait cycle showed statistically significant differences between the no-PRF and the healthy group (p < .005). No differences were found between the PRF and healthy groups. Treatment with suture and PRF augmentation could result in significant functional improvements in term of efficiency of motion.

To review 20 years of experience of the removal of intra-abdominal intrauterine devices (IUDs) and to compare the surgical methods used. In a retrospective study, charts dating from between September 1, 1992, and August 31, 2012, were reviewed. Patients were eligible for inclusion when they had an IUD surgically removed by minilaparotomy or laparoscopy at a tertiary referral center in Izmir, Turkey. Among the 36 eligible women, 18 (50%) had undergone laparoscopy and 18 (50%) had undergone minilaparotomy. Mean operation length was 55.3±6.3 minutes in the laparoscopy group and 29.1±4.2 minutes in the minilaparotomy group (P=0.008). Conversion to full laparotomy was necessary in 4 (22%) women in the laparoscopy group and 1 (6%) in the minilaparotomy group (P=0.02). Perioperative complications were observed in 5 (14%) women, with no difference in frequency between groups (P=0.09). Total cost of medical/surgical procedures was US$436.4±35.4 for the laparoscopy group and $323.4±21.3 for the minilaparotomy group (P=0.04). Minilaparotomy seems to be an important alternative to laparoscopy for the removal of intra-abdominal IUDs. This procedure should be an integral part of gynecologic surgical training.

The aim of this study was to describe changes over time in the indications and outcomes of cataract surgery and to discuss optimal timing for the surgery. Database study. Patients who had undergone cataract extraction in the Netherlands, Sweden, or Malaysia from 2008 through 2012. We analyzed preoperative, surgical, and postoperative data from 2 databases: the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) and the Malaysian National Cataract Registry. The EUREQUO contains complete data from the national cataract registries in the Netherlands and Sweden. Preoperative and postoperative corrected distance visual acuity, preoperative ocular comorbidity in the surgery eye, and capsule complications during surgery. There were substantial differences in indication for surgery between the 3 national data sets. The percentage of eyes with a preoperative best-corrected visual acuity of 20/200 or worse varied from 7.1% to 72%. In all 3 data sets, the visual thresholds for cataract surgery decreased over time by 6% to 28% of the baseline values. The frequency of capsule complications varied between the 3 data sets, from 1.1% to 3.7% in 2008 and from 0.6% to 2.7% in 2012. An increasing postoperative visual acuity was also seen for all 3 data sets. A high frequency of capsule complication was related significantly to poor preoperative visual acuity, and a high frequency of decreased visual acuity after surgery was related significantly to excellent preoperative visual acuity. The 5-year trend in all 3 national data sets showed decreasing visual thresholds for surgery, decreasing surgical complication rates, and increasing visual outcomes regardless of the initial preoperative visual level. Cataract surgery on eyes with poor preoperative visual acuity was related to surgical complications, and cataract surgery on eyes with excellent preoperative visual acuity was related to adverse visual results.

Xu, Yansong; Tang, Weizhong

2017-01-01

Since 2007, ligation of the intersphincteric fistula tract (LIFT) for the management of anal fistula was all introduced with initial success and excitement. It remains controversial which surgical procedure is suitable for transsphincteric fistula, especially to complex anal fistula. This retrospective study was designed to evaluate the results in patients with recurrent anal fistula by LIFT. A retrospective study of 55 complex fistula patients who underwent LIFT procedure in a single medical center was analyzed. Patients and fistula characteristics, complications, and recurrences were reviewed. All 55 patients underwent the procedure with a median follow-up of 16 months. Median operative time was 44 (range 23-88) minutes. Of the 55 patients, 33 (60%) healed completely and did not require any further surgical treatment at end of follow-up. Twenty-two (40%) recurrences and six complications were observed. Compared with patients who had undergone more than two surgical procedures, LIFT was more suitable for patients who had undergone one to two surgical procedures, and significant difference was observed in number of operations before LIFT ( p = 0.002). Clinicians can consider the use of LIFT for the treatment of recurrent anal fistulas. A larger number of patients and prospective study are needed to be performed.

2017-09-01

Rhinoplasty is one of the oldest known surgeries to the human kind. However, being a cosmetic of surgery of utmost importance, it has been an attractive and fascinating surgery for the otolaryngologists and plastic surgeons. Along with the evolution of improved techniques and better surgical modalities, this surgery has been growing in panorama including its indications, needs and techniques. We present our experience with rhinoplasty in a tertiary care center of north India. We have included all cases operated with septorhinoplasty from 2001 to 2014 by the senior author in the manuscript. We reviewed their presentations, investigations, preoperative counselling records, operative details and post-operative clinical records to audit our results and hence to document our experiences in septorhinoplasties. A total of 53 cases including 37 males and 16 females had undergone rhinoplasty surgeries. The most common reason of disfigurement was road traffic accident (58.5%). All these patients included different deformities and required varied corrections. There were no major post-operative complications except persistent edema with longest lasting for 23 weeks. Thermal splints gave a better patient satisfaction in post-op compared to POP splints. Results were completely and partially satisfying for 50 patients and not satisfying for three. Unrealistic expectations from the procedure might be the reason for non-satisfactory results in rhinoplasty. Rhinoplasty is a delicate procedure and has greater aesthetic implications in planning surgical techniques and approaches. For better satisfaction of patients, adequate preoperative counseling and realistic expectations are warranted. Skillful surgical techniques null chances of complications.

Fetus dose estimation in thyroid cancer post-surgical radioiodine therapy.

PubMed

Mianji, Fereidoun A; Diba, Jila Karimi; Babakhani, Asad

2015-01-01

Unrecognised pregnancy during radioisotope therapy of thyroid cancer results in hardly definable embryo/fetus exposures, particularly when the thyroid gland is already removed. Sources of such difficulty include uncertainty in data like pregnancy commencing time, amount and distribution of metastasized thyroid cells in body, effect of the thyroidectomy on the fetus dose coefficient etc. Despite all these uncertainties, estimation of the order of the fetus dose in most cases is enough for medical and legal decision-making purposes. A model for adapting the dose coefficients recommended by the well-known methods to the problem of fetus dose assessment in athyrotic patients is proposed. The model defines a correction factor for the problem and ensures that the fetus dose in athyrotic pregnant patients is less than the normal patients. A case of pregnant patient undergone post-surgical therapy by I-131 is then studied for quantitative comparison of the methods. The results draw a range for the fetus dose in athyrotic patients using the derived factor. This reduces the concerns on under- or over-estimation of the embryo/fetus dose and is helpful for personal and/or legal decision-making on abortion. © The Author 2014.

2014-12-01

This paper is a comparative photometric evaluation of soft tissue changes in patients with CLP associated with maxillary deficiency treated with conventional Le Fort I advancement osteotomy (ALO) and anterior maxillary distraction (AMD). Twenty patients with maxillary hypoplasia associated with cleft lip and palate who had undergone either LeFort I osteotomy or distraction osteogenesis with maxillary advancement were included in this study. Frontal and profile photographs were used to ascertain the changes post-surgically. Photographs were obtained before treatment and 1 year after surgical correction in both groups. Vertical as well as horizontal changes in pronasale was well observed in both groups. A substantial increase in nasal parameters was noted in case of AMD group in comparison to ALO group. Though maxillary advancement was quite evident in AMD and ALO groups, a significant and consistent change was observed in AMD group. Significant vertical and horizontal changes were seen with respect to subnasale and labrale superius in AMD group. The hard and soft tissue changes produced by AMD by intra oral distractors were being evaluated so far. The results of the above studies have proved the excellence of AMD over conventional osteotomies. The present study goes hand in hand with the research outcomes till date.

Primary care needs of patients who have undergone gender reassignment.

2005-04-01

The purpose of this article is to inform nurse practitioners (NPs) about the primary care needs of patients who have undergone gender reassignment, either by hormone therapy alone or in conjunction with surgery. Data sources used were mainly from a review of the literature about gender identity disorder and gender reassignment. Information was also gathered from several leading surgeons on gender reassignment surgical procedures and subsequent clinical considerations. There is very little written on the primary care clinical ramifications of transsexual patients and how clinicians can adapt their approaches to healthcare delivery to accommodate their special situations. Implications for practice include how an NP can adapt clinical practice approaches to provide for patients who have undergone gender reassignment. Changes that occur in the transsexual process may warrant noncustomary primary healthcare screening and examination.

The mainstay of surgical correction of hallux valgus is first metatarsal osteotomy, either proximally or distally. We present a technique of combining a distal chevron osteotomy with a proximal opening wedge osteotomy, for the correction of moderate to severe hallux valgus. We reviewed 45 patients (49 feet) who had undergone double osteotomy. Outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) and the Short Form (SF) -36 Health Survey scores. Radiological measurements were undertaken to assess the correction. The mean age of the patients was 60.8 years (44.2 to 75.3). The mean follow-up was 35.4 months (24 to 51). The mean AOFAS score improved from 54.7 to 92.3 (p < 0.001) and the mean SF-36 score from 59 to 86 (p < 0.001). The mean hallux valgus and intermetatarsal angles were improved from 41.6(o) to 12.8(o) (p < 0.001) and from 22.1(o) to 7.1(o), respectively (p < 0.001). The mean distal metatarsal articular angle improved from 23(o) to 9.7(o). The mean sesamoid position, as described by Hardy and Clapham, improved from 6.8 to 3.5. The mean length of the first metatarsal was unchanged. The overall rate of complications was 4.1% (two patients). These results suggest that a double osteotomy of the first metatarsal is a reliable, safe technique which, when compared with other metatarsal osteotomies, provides strong angular correction and excellent outcomes with a low rate of complications.

Cohort study examining long-term respiratory health, career duration and racing performance in racehorses that undergo left-sided prosthetic laryngoplasty and ventriculocordectomy surgery for treatment of left-sided laryngeal hemiplegia.

PubMed

The risk of respiratory conditions, such as inflammatory airway disease (IAD) and exercise-induced pulmonary haemorrhage (EIPH), are thought to be higher in racehorses that undergo prosthetic laryngoplasty with ventriculocordectomy (PLVC) surgery to treat left-sided laryngeal hemiplegia (LLH) than in racehorses with normal laryngeal function. However, this has not been investigated formally owing to the difficulty of obtaining reliable follow-up data. To determine the incidence of respiratory conditions (IAD and EIPH), duration of racing career, number of starts and number of starts for which stakes money was earned in racehorses that had undergone PLVC surgery to treat LLH, compared with racehorses that did not have LLH or undergo any laryngeal surgery. A retrospective cohort study design was used, with surgical, clinical and race data of Thoroughbred racehorses obtained from the time of importation until retirement. The surgical cohort consisted of racehorses that had undergone PLVC for LLH and met specific inclusion criteria. Every surgical case was matched, according to trainer, year of import into Hong Kong and pre-import international handicap rating, to 2 unexposed racehorses. Respiratory conditions, such as excessive tracheal mucus and epistaxis due to severe EIPH, were significantly increased in the surgical cohort, compared with the matched unexposed cohort (P values <0.001 and <0.004, respectively). Racing career duration in the surgical cohort was significantly shorter than in the unexposed cohort, which was primarily due to retirement because of epistaxis. The number of race starts was fewer in the surgical than in the unexposed cohort after surgery/matching, but the number of starts for which stakes money was earned was not significantly different. Owners and trainers should be advised that racehorses with LLH that undergo PLVC surgery are at an increased risk of respiratory conditions (IAD and severe EIPH), which is likely to shorten their racing career compared to racehorses with normal laryngeal function. Racing performance in terms of race starts was significantly less in racehorses that had undergone PLVC surgery; however, the number of starts for which stakes money was earned was similar to those racehorses that were unexposed. © 2012 EVJ Ltd.

Cardiovascular magnetic resonance (CMR) imaging can predict hemodynamically significant coarctation of the aorta (CoA) with a high degree of discrimination. However, the ability of CMR to predict important clinical outcomes in this patient population is unknown. Therefore, we sought to define the ability of CMR to predict the need for surgical or transcatheter intervention in patients with CoA. We retrospectively reviewed the data from 133 consecutive patients who had undergone CMR for the evaluation of known or suspected CoA. The characteristics of the CMR-derived variables predicting the need for surgical or transcatheter intervention for CoA within 1 year were determined through logistic regression analysis. Therapeutic aortic intervention was performed in 41 (31%) of the 133 patients during the study period. The indexed minimum aortic cross-sectional area was the strongest predictor of subsequent intervention (area under the receiver operating characteristic curve 0.975) followed by heart rate-corrected deceleration time in the descending aorta (area under the receiver operating characteristic curve 0.951), and the percentage of flow increase (area under the receiver operating characteristic curve 0.867). The combination of the indexed minimum aortic cross-sectional area and rate-corrected deceleration time in the descending aorta provided the best predictive model (area under the receiver operating characteristic curve 0.986). In conclusion, CMR findings can predict the need for subsequent intervention in CoA. These findings reinforce the "gate-keeper role" of CMR to cardiac catheterization by providing valuable diagnostic and powerful prognostic information and could guide additional treatment of patients with CoA with the final intent of reducing the number of diagnostic catheterizations in such patients.

To determine the optimal moment to carry out a tracheostomy in a patient requiring anterior cervical fixation. A retrospective observational study was carried out over an 18-year period on 56 patients who had been admitted to the ICU with acute spinal cord injury (SCI), and who underwent a tracheostomy and surgical fixation. The sample was divided into two groups: An at-risk group (31 patients, who had undergone a tracheostomy prior to the cervical surgery or <4 days after the procedure), and a not at-risk group (25 patients, who had undergone a tracheostomy >4 day following the fixation surgery). Both a descriptive and a comparative study were carried out. The overall trend of the collected data was analysed using cubic splines (graphic methods). The only infectious complications diagnosed as related to the surgical procedure were infection of the surgical wound in two patients of the not at-risk group (12%) and deep-tissue infection in one patient of the at-risk group (3.2%). During the study period, we identified a tendency towards the conduct of early tracheostomies. Our results suggest that the presence of a tracheostomy stoma prior to, or immediately after surgery, is associated with a low risk of infection of the cervical surgical wound in instrumented spinal fusion.

Fractures of the tibial plateau are among the most severe injuries of the knee joint and lead to advanced gonarthrosis if the reduction does not restore perfect joint congruency. Many different reduction techniques focusing on open surgical procedures have been described in the past. In this context we would like to introduce a novel technique which was first tested in a cadaver setup and has undergone its successful first clinical application. Since kyphoplasty demonstrated effective ways of anatomical correction in spine fractures, we adapted the inflatable instruments and used the balloon technique to reduce depressed fragments of the tibial plateau. The technique enabled us to restore a congruent cartilage surface and bone reduction. In this technique we see a useful new method to reduce depressed fractures of the tibial plateau with the advantages of low collateral damage as it is known from minimally invasive procedures.

One-stage posterior hemivertebral resection has been proven to be an effective, reliable surgical option for treating congenital scoliosis due to a single hemivertebra. To date, however, no studies of treating unbalanced multiple hemivertebrae have appeared. This study evaluated the efficacy and safety of one-stage posterior hemivertebral resection for unbalanced multiple hemivertebrae. Altogether, we studied 15 patients with unbalanced multiple hemivertebrae who had undergone hemivertebral resection using the one-stage posterior approach with at least 2 years of follow-up. Clinical outcomes were assessed radiographically and with the Scoliosis Research Society-22 (SRS-22) score. Related complications were also recorded. The mean Cobb angle of the main curve was 62.4° (46°-98°) before surgery and 18.2° (9°-33°) at the most recent follow-up (average correction 73.3%). The compensatory cranial curve was corrected from 28.5° (11°-52°) to 9.1° (0°-30°) (average correction 70.0%). The compensatory caudal curve was corrected from 31.6° (14°-54°) to 6.9°(0°-19°) (average correction 79.1%). The segmental kyphosis/lordosis was corrected from 41.1° (-40° to 98°) to 12.3° (-25° to 41°) (average correction 65.5%). The mean growth rate of the T1-S1 length in immature patients was 9.8mm/year during the follow-up period. Health-related quality of life (SRS-22 score) had significantly improved. Complications include one wound infection and one developing deformity.

To explore possible reasons for the incidence of a pituitary abscess following transsphenoidal surgery and determine the most effective treatment. A series of 12 patients who had undergone transsphenoidal surgery in other hospitals before being treated at Peking Union Medical College Hospital were reviewed. The presence of a pituitary abscess was confirmed when pus was intraoperatively observed within the sella turcica. All patients were treated with debridement of the abscess, nine among whom through a transsphenoidal approach and the other three via a craniotomy, followed by antibiotic treatment and hormone replacement therapy. The mean follow-up time was 27.0 months (range from 3.0 to 79.0 months). Headache (92%), panhypopituitarism (58%) and visual disturbance (50%) were the most common clinical indicators of a pituitary abscess. Imaging tests demonstrated a pituitary mass in all patients, with seven (58%) manifested with typical magnetic resonance features of an abscess. Ten patients (83%) were correctly diagnosed preoperatively. During surgical exploration, six presented with severe inflammation or an abscess within the sphenoidal sinus. Causative organisms were identified in five patients (42%). After surgical and antibiotic therapies, all patients fully recovered except for two presenting with severe visual impairment. Six patients (50%) required hormone replacement therapy. Retrograde infection from the sphenoid sinus may be a vital mechanism underlying the formation of a pituitary abscess following transsphenoidal surgery. Debridement of the abscess through surgical approaches combined with antibiotic treatment has been found to yield positive outcomes. Copyright © 2014 Elsevier B.V. All rights reserved.

Preoperative non-surgical over-correction of cleft lip nasal deformity.

Alar cartilage, which is elastic like auricular cartilage, is correctable in the early neonatal period. Taking advantage of this correctability, we have performed preoperative non-surgical over-correction for cleft lip nasal deformity of incomplete and complete cleft lips with a Simonart's band. The device for this correction was made by processing a nostril retainer into a nostril over-corrector which utilises a spring of silicone rubber, works like a tissue expander and is supported by the nostril floor. Twenty cases are reviewed whose follow-up lasted more than 19 months. The earlier the non-surgical over-correction began, the more satisfactory were the results that were obtained.

Robotic surgery (RS) technology has undergone rapid growth in the surgical field since its approval. In clinical practice, failure of robotic procedures mainly results from a surgeon's inability or to a device malfunction. We reviewed the literature to estimate the impact of this second circumstance in RS and its consequent legal implications. According to data from the literature, device malfunction is rare. We believe it is necessary to complement surgical training with a technical understanding of RS devices.

Carcinoma of the cervix and sexual function.

Forty-six patients were interviewed more than a year after treatment for carcinoma of the cervix to establish the effects of radiation therapy and of surgical therapy on sexual feelings and performance. Group 1 consisted of 22 patients who had undergone radiation therapy for stage I, II, or III cancer of the cervix. Group 2 consisted of 20 patients who had undergone hysterectomy with or without partial vaginectomy for carcinoma in situ. The irradiated patients experienced statistically significant decreases in sexual enjoyment, ability to attain orgasm, libido, frequency of intercourse, opportunity, and sexual dreams. The surgically treated group had no significant change in sexual function after treatment. Both groups experienced a change in self-image but did not feel that their partners or family viewed them differently. Myths about cancer and the actual effects of pelvic irradiation were found to have disrupted the sexual-marital relationships of many women. Therapeutic programs are discussed through which women can be helped through this difficult time in their lives.

Atrial fibrillation (AF) is the most common cardiac arrhythmia and a huge public health burden associated with significant morbidity and mortality. For decades an increasing number of patients have undergone surgical treatment of AF, mainly during concomitant cardiac surgery. This has sparked a drive for conducting further studies and researching this field. With the cornerstone Cox-Maze III “cut and sew” procedure being technically challenging, the focus in current literature has turned towards less invasive techniques. The introduction of ablative devices has revolutionised the surgical management of AF, moving away from the traditional surgical lesions. The hybrid procedure, a combination of catheter and surgical ablation is another promising new technique aiming to improve outcomes. Despite the increasing number of studies looking at various aspects of the surgical management of AF, the literature would benefit from more uniformly conducted randomised control trials.

This case report describes the use of real-time intraoperative ultrasonography to guide the removal of an airgun pellet embedded in the right cheek of a 20-year-old man. This patient had previously undergone two unsuccessful surgical attempts to have this pellet removed via blind exploration. Through the use of ultrasonography, the pellet's positional relationship throughout the procedure was accurately defined with respect to important soft and hard anatomical structures, as well as to the surgical instruments used, enabling its very efficient removal. This technique is safe, easy, cost effective and accurate, and thus minimizes post-operative morbidity and the risk of surgical complications.

Pectus excavatum is the most common congenital deformity of the anterior chest wall, in which several ribs and the sternum grow abnormally. Nowadays, the surgical correction is carried out in children and adults through Nuss technic. This technic has been shown to be safe with major drivers as cosmesis and the prevention of psychological problems and social stress. Nowadays, no application is known to predict the cosmetic outcome of the pectus excavatum surgical correction. Such tool could be used to help the surgeon and the patient in the moment of deciding the need for surgery correction. This work is a first step to predict postsurgical outcome in pectus excavatum surgery correction. Facing this goal, it was firstly determined a point cloud of the skin surface along the thoracic wall using Computed Tomography (before surgical correction) and the Polhemus FastSCAN (after the surgical correction). Then, a surface mesh was reconstructed from the two point clouds using a Radial Basis Function algorithm for further affine registration between the meshes. After registration, one studied the surgical correction influence area (SCIA) of the thoracic wall. This SCIA was used to train, test and validate artificial neural networks in order to predict the surgical outcome of pectus excavatum correction and to determine the degree of convergence of SCIA in different patients. Often, ANN did not converge to a satisfactory solution (each patient had its own deformity characteristics), thus invalidating the creation of a mathematical model capable of estimating, with satisfactory results, the postsurgical outcome.

Facial appearance and speech outcome may affect psychosocial functioning in girls and boys. Several studies reported dissatisfaction with facial appearance and more specifically the lip and mouth profile in children with cleft lip and palate (CLP). The purpose of this controlled study was to measure the tongue and lip strength and endurance in boys and girls with CLP. Twenty-five subjects (mean age: 10.6 years) with a unilateral CLP and a gender- and age- matched control group were selected. All subjects with an unilateral CLP consulted the same craniofacial team and had undergone an identical surgical procedure. Surgical procedure of the lip was performed using a modified Millard technique without primary nose correction at an average age of 5.5 months. The Iowa Oral Performance instrument was used to measure lip and tongue strength and tongue endurance. The results of the Iowa Oral Performance measurement showed no significant differences between the subjects with an unilateral cleft lip and palate and the age and gender matched control group without a cleft lip and palate. There is no significant differences regarding oral strength more specifically the lip and tongue strength and endurance between subjects with and without an unilateral cleft lip and palate. ENT specialists and speech pathologists must be aware of this aspect of the normal lip and tongue functions. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Double calcaneal osteotomy with percutaneous Steinmann pin fixation as part of treatment for flexible flatfoot deformity: a review of consecutive cases highlighting our experience with pin fixation.

PubMed

Boffeli, Troy J; Abben, Kyle W

2015-01-01

Surgical correction of flexible flatfoot deformity and posterior tibial tendon dysfunction has been extensively reported in published studies. When appropriate, calcaneal osteotomies for flatfoot correction have been a favorite of foot and ankle surgeons because of the corrective power achieved without the need to fuse any rearfoot joints. The medial displacement calcaneal osteotomy and Evans calcaneal osteotomy, together termed the double calcaneal osteotomy, have been reported several times by various investigators with a wide variety of fixation options. We undertook an institutional review board-approved retrospective review of 9 consecutive patients (11 feet), who had undergone double calcaneal osteotomy with 2 percutaneous Steinmann pin fixation for the correction of flexible flatfoot deformity, with or without posterior tibial tendon dysfunction. All patients had radiographic evidence of bone healing of the posterior calcaneal osteotomy and incorporation of the Evans osteotomy bone graft at 6 weeks and demonstrated clinical healing at 6 weeks. All patients had 2 percutaneous Steinmann pins placed through both osteotomies, and these were removed an average of 6 weeks postoperatively. No patient developed pin site complications. The only complication noted was sural neuritis, which was likely incision related. No patients had delayed union or nonunion, and we did not identify any graft shifting postoperatively. The present retrospective series highlights our experience with 2 percutaneous Steinmann pin fixation, demonstrating equal or better results than many previous published fixation methods for double calcaneal osteotomy. It is cost-effective and minimizes the potential risk of iatrogenic Achilles pathologic features associated with screw fixation. Copyright © 2015 American College of Foot and Ankle Surgeons.

2013-05-01

Lateral column lengthening (LCL) has been shown to radiographically restore the medial longitudinal arch. However, the impact of LCL on foot function during gait has not been reported using validated clinical outcomes and gait analysis. Thirteen patients with a stage II flatfoot who had undergone unilateral LCL surgery and 13 matched control subjects completed self-reported pain and functional scales as well as a clinical examination. A custom force transducer was used to establish the maximum passive range of motion of first metatarsal dorsiflexion at 40 N of force. Foot kinematic data were collected during gait using 3-dimensional motion analysis techniques. Radiographic correction of the flatfoot was achieved in all cases. Despite this, most patients continued to report pain and dysfunction postoperatively. Participants post LCL demonstrated similar passive and active movement of the medial column when we compared the operated and the nonoperated sides. However, participants post LCL demonstrated significantly greater first metatarsal passive range of motion and first metatarsal dorsiflexion during gait than did controls (P < .01 for all pairwise comparisons). Patients undergoing LCL for correction of stage II adult-acquired flatfoot deformity experience mixed outcomes and similar foot kinematics as the uninvolved limb despite radiographic correction of deformity. These patients maintain a low arch posture similar to their uninvolved limb. The consequence is that first metatarsal movement operates at the end range of dorsiflexion and patients do not obtain full hindfoot inversion at push-off. Longitudinal data are necessary to make a more valid comparison of the effects of surgical correction measured using radiographs and dynamic foot posture during gait. Level III, comparative series.

A case of thoracic splenosis in a post-splenectomy patient following abdominal trauma: Hello Howell-Jolly.

PubMed

Viviers, Petrus J

2014-08-01

Seeding of splenic tissue to extra-abdominal sites is a relatively infrequent consequence of open abdominal trauma. Immunological function of these small foci of ectopic splenic tissue is unknown and their use in determining the splenic function may be limited. In this case report, a patient is described who had previously undergone an emergency splenectomy. The absence of Howell-Jolly bodies on the blood smear in a patient who had previously undergone surgical splenectomy raised the suspicion of splenosis. The immunological features as well as non-invasive evaluation of these ill-defined splenic tissue sites are discussed.

In a previous report, we described a method of reconstruction using tumor-bearing autograft treated by liquid nitrogen for malignant bone tumor. Here we present the first case of bone deformity correction following a tumor-bearing frozen autograft via three-dimensional computerized reconstruction after multiple surgeries. A 16-year-old female student presented with pain in the left lower leg and was diagnosed with a low-grade central tibial osteosarcoma. Surgical bone reconstruction was performed using a tumor-bearing frozen autograft. Bone union was achieved at 7 months after the first surgical procedure. However, local tumor recurrence and lung metastases occurred 2 years later, at which time a second surgical procedure was performed. Five years later, the patient developed a 19° varus deformity and underwent a third surgical procedure, during which an osteotomy was performed using the Taylor Spatial Frame three-dimensional external fixation technique. A fourth corrective surgical procedure was performed in which internal fixation was achieved with a locking plate. Two years later, and 10 years after the initial diagnosis of tibial osteosarcoma, the bone deformity was completely corrected, and the patient's limb function was good. We present the first report in which a bone deformity due to a primary osteosarcoma was corrected using a tumor-bearing frozen autograft, followed by multiple corrective surgical procedures that included osteotomy, three-dimensional external fixation, and internal fixation.

Hepatic artery pseudoaneurysms (HAPs) are uncommon entities. With the development of interventional techniques, their management has evolved from conventional (surgical) to non-surgical minimally invasive image-guided interventional techniques. Fifteen cases of HAPs who had undergone non-surgical interventional management in our department were reviewed. All patients were comprehensively evaluated for demographic information, morphology of pseudoaneurysm, indication for intervention and means of intervention, approach (endovascular or percutaneous), follow up and complications. Trauma and iatrogenic injury were most common causes of HAPs. Most of the HAPs (9 out of 10 in whom long follow up was available) managed with image-guided interventional techniques had favorable outcome. Minimally invasive image-guided interventional management is the preferred modality for HAPs.

A qualitative identification of categories of patient participation in decision-making by health care professionals and patients during surgical treatment.

Heggland, Liv-Helen; Hausken, Kjell

2013-05-01

The aim of this article is to identify how health care professionals and patients experience patient participation in decision-making processes in hospitals. Eighteen semi-structured interviews with experts from different disciplines such as medicine and nursing in surgical departments as well as patients who have undergone surgical treatment constitute the data. By content analysis four categories of patient participation were identified: information dissemination, formulation of options, integration of information, and control. To meet the increasing demands of patient participation, this categorization with four identified critical areas for participation in decision-making has important implications in guiding information support for patients prior to surgery and during hospitalization.

Spinal kyphotic deformity occasionally results in gastroesophageal reflux disease (GERD). The effects of acid reflux on the esophagus in kyphotic patients are unclear, however, and it is unknown whether acid reflux, endoscopic GERD, and reflux-related symptoms improve following surgical spinal correction in these patients. Herein, we investigated the characteristics of GERD in kyphotic patients and the improvement in GERD following surgical correction. In 48 patients with severe kyphotic deformity scheduled for surgical spinal correction, we conducted esophagogastroduodenoscopy, 24-h pH monitoring and three questionnaire surveys, including the frequency scale for the symptoms of GERD (FSSG). We repeated these measurements after surgical correction and compared pre- and post-surgery values. Of 48 patients, 70.8% [95% CI: 55.9-83.0%, 34/48] had endoscopically evaluated esophageal mucosal injury. Regarding pH before surgery, 64.9% (CI: 47.5-79.8%, 24/37) had abnormal acid reflux (intraesophageal pH < 4 more than 5% of the time). FSSG score was significantly associated with the severity of GERD, and the positive rate was 52.6% (CI: 35.8-69.0%, 20/38). Following surgical correction, esophageal mucosal injury improved endoscopically in 90% of patients, and median total FSSG score significantly decreased from 8 (0-30) to 5 (0-19) (P = 0.005). Regarding pH after surgery, prevalence of abnormal acid reflux decreased from 66.7% (95% CI: 41.0-86.7%) to 33.3% (95% CI: 13.3-59.0%) (P = 0.045). Surgical spinal correction in kyphosis patients improves not only kyphotic deformity-related disorders but also esophageal mucosal injury, abnormal acid reflux, and reflux-related symptoms. © 2015 Japan Gastroenterological Endoscopy Society.

Idiopathic scoliosis: the tethered spine II: post-surgical pain.

PubMed

Whyte Ferguson, Lucy

2014-10-01

The treatment of severe chronic pain in young people following surgery for the correction of curvatures of idiopathic scoliosis (IS) is presented through two case histories. Effective treatment involved release of myofascial trigger points (TrPs) known to refer pain into the spine, and treatment of related fascia and joint dysfunction. The TrPs found to be contributing to spinal area pain were located in muscles at some distance from the spine rather than in the paraspinal muscles. Referred pain from these TrPs apparently accounted for pain throughout the base of the neck and thoracolumbar spine. Exploratory surgery was considered for one patient to address pain following rod placement but the second surgery became unnecessary when the pain was controlled with treatment of the myofascial pain and joint dysfunction. The other individual had both scoliosis and hyperkyphosis, had undergone primary scoliosis surgery, and subsequently underwent a second surgery to remove hardware in an attempt to address her persistent pain following the initial surgery (and because of dislodged screws). The second surgery did not, however, reduce her pain. In both cases these individuals, with severe chronic pain following scoliosis corrective surgery, experienced a marked decrease of pain after myofascial treatment. As will be discussed below, despite the fact that a significant minority of individuals who have scoliosis corrective surgery are thought to require a second surgery, and despite the fact that pain is the most common reason leading to such revision surgery, myofascial pain syndrome (MPS) had apparently not previously been considered as a possible factor in their pain.

Surgery in octogenarians with acute type A aortic dissection is commonly avoided or denied because of the high surgical morbidity and mortality reported in elderly patients. We sought to compare clinical and quality of life outcomes between octogenarians and those aged less than 80 years who underwent surgical repair at New York Medical College. A total of 101 cases of acute type A aortic dissection repair between July 2005 and December 2011 were retrospectively analyzed, comparing 21 octogenarians with 80 concurrent patients aged less than 80 years. All patients underwent corrective surgery (ascending/hemiarch replacement in 71; Bentall in 22; David procedure in 2; Wheat procedure in 4; total arch replacement in 2) using deep hypothermic circulatory arrest. During follow-up, the RAND 36-Item Short Form Health Survey Questionnaire was used to assess quality of life. Octogenarians (average, 85 years; range, 80-91 years) were compared with the younger group (average, 60 years; range, 30-79 years). The 2 groups had similar preoperative characteristics, but the younger group experienced more malperfusion (40% vs 9%, P = .002), were more likely to have undergone a Bentall procedure (26% vs 5%, P = .04), and had longer circulatory arrest times (20 ± 7 minutes vs 16 ± 9 minutes, P = .03). The overall hospital mortality was 9% (9/101). Among octogenarians, there were no hospital deaths, no late deaths during follow-up (mean, 17 months; range, 1-59 months), and emotional health scores were better than those of the younger patients (P = .04). Surgery for acute type A aortic dissection should be offered to octogenarians because excellent surgical and quality of life outcomes can be achieved even in this elderly population.

The present study was designed to evaluate the role of intraoperative ultrasound (IOUS) in intrahepatic staging and the impact on surgical strategy for patients with colorectal liver metastases (CRLM). The study included 515 patients who had undergone liver resection for CRLM at two tertiary care referral centers. Data from a prospectively collected database were retrospectively analysed. Early intrahepatic recurrence was assessed at 3 and 6 months after resection and was considered as residual disease undetected by IOUS. Performance of imaging modalities was compared by analysis of studies on individual patients. A total of 1,370 liver metastases were detected preoperatively with a median of 3 imaging modalities. MRI and PET were performed in 51 and 42 % of the patients, respectively. Median number of days between last imaging and surgery was 18. Contrast-enhanced IOUS was performed in 136 patients (26.4 %). Intraoperatively, 293 new nodules were found in 132 patients: on histology 280 were CRLM (17.6 %). Surgical strategy was changed in 140 patients (27.2 %). On multivariate analysis synchronous and bilobar metastases ≥ 3 in number, BMI ≥ 30, and time between last imaging and surgery longer than 18 days resulted in predictive factors indicating new nodules detected by IOUS. Early intrahepatic recurrences were 3.7 and 7.9 % at 3 and 6 months. Performance of CT, MRI, FDG-PET, and intraoperative staging was compared: sensitivity was 63.6, 68.8, 53.6, and 92 % and specificity was 91, 92.3, 95.8, and 97.8 %, respectively The use of IOUS continues to be mandatory for correct staging of patients with CRLM undergoing liver resection.

Results of arthroscopic joint debridement in different stages of chondromalacia of the knee joint.

PubMed

Krüger, T; Wohlrab, D; Birke, A; Hein, W

2000-01-01

A retrospective study was performed of 161 patients who had undergone arthroscopic operation for chondromalacia of the knee joint. After an average follow-up period of 40 (range 10-72) months, patients with severe articular cartilage lesions who had undergone articular lavage alone showed significantly poorer results (P < 0.001). With the same stage of chondromalacia and having undergone the same surgical procedure, younger patients showed better results than older patients. The more effective interruption of the circulus vitiosus during the development of degenerative joint diseases is the primary cause for better results achieved by mechanical debridement of the joint for patients suffering from grade 2 or higher. According to the literature, aggressive subchondral abrasion in severely degenerated knees does not show any benefits. Apparently, the success of the therapy depends to a great extent on the inferiority of the potential degenerative regenerate (lack of capacity of intrinsic regeneration of the hyaline cartilage) as well as on the grade and the progression of chondromalacia. Almost every second patient suffering from grade 4 chondromalacia complained of recurrent pain 1 year postoperatively. One of every 6 patients received a knee joint prosthesis within the 1st year. Therefore, the patients' preoperative expectations have to be clearly objectified. The surgical procedure as an operation with a low complication risk can also be justified as a temporary alternative to total knee arthroplasty in patients suffering from a high-grade degeneration of the joint.

Traditionally, maxillofacial deformities are corrected surgically after an initial orthodontic treatment phase. However in, this article, the authors emphasize the postsurgical therapeutic protocol which is extremely important for determining the final and permanent retention of the corrected occlusion. A 55 year old female with severe skeletal Class II malocclusion is presented. Combined surgical and orthodontic correction of the malocclusion was used. : The step-by-step procedure the authors followed for the postsurgical therapy is described. The goals of the postoperative therapy were to restore and rehabilitate neuromuscular function, obtain occlusal stabilization, grind teeth selectively, and final occlusion retention. The importance of a surgical occlusal splint for rehabilitating stomatognathic neuromuscular function postoperatively was demonstrated. Furthermore, the orthodontic-prosthodontic treatment ensured occlusion stability after the surgical correction. The long-term results confirmed the efficacy of the treatment protocol presented here from both functional and aesthetical perspectives. Postsurgical orthodontic treatment is an important step in the surgical and orthodontic therapy of maxillofacial deformities.

Computer-assisted versus non-computer-assisted preoperative planning of corrective osteotomy for extra-articular distal radius malunions: a randomized controlled trial.

Malunion is the most common complication of distal radius fracture. It has previously been demonstrated that there is a correlation between the quality of anatomical correction and overall wrist function. However, surgical correction can be difficult because of the often complex anatomy associated with this condition. Computer assisted surgical planning, combined with patient-specific surgical guides, has the potential to improve pre-operative understanding of patient anatomy as well as intra-operative accuracy. For patients with malunion of the distal radius fracture, this technology could significantly improve clinical outcomes that largely depend on the quality of restoration of normal anatomy. Therefore, the objective of this study is to compare patient outcomes after corrective osteotomy for distal radius malunion with and without preoperative computer-assisted planning and peri-operative patient-specific surgical guides. This study is a multi-center randomized controlled trial of conventional planning versus computer-assisted planning for surgical correction of distal radius malunion. Adult patients with extra-articular malunion of the distal radius will be invited to enroll in our study. After providing informed consent, subjects will be randomized to two groups: one group will receive corrective surgery with conventional preoperative planning, while the other will receive corrective surgery with computer-assisted pre-operative planning and peri-operative patient specific surgical guides. In the computer-assisted planning group, a CT scan of the affected forearm as well as the normal, contralateral forearm will be obtained. The images will be used to construct a 3D anatomical model of the defect and patient-specific surgical guides will be manufactured. Outcome will be measured by DASH and PRWE scores, grip strength, radiographic measurements, and patient satisfaction at 3, 6, and 12 months postoperatively. Computer-assisted surgical planning, combined with patient-specific surgical guides, is a powerful new technology that has the potential to improve the accuracy and consistency of orthopaedic surgery. To date, the role of this technology in upper extremity surgery has not been adequately investigated, and it is unclear whether its use provides any significant clinical benefit over traditional preoperative imaging protocols. Our study will represent the first randomized controlled trial investigating the use of computer assisted surgery in corrective osteotomy for distal radius malunions. NCT01193010.

To analyze early postoperative period in patients with diffuse pulmonary emphysema after palliative surgical correction of respiratory failure. The study included 196 patients who underwent bullectomy (n=111) and surgical reduction of pulmonary volume (n=85). Overall morbidity and mortality were 40.8% and 12.2% respectively. Among patients older than 60 years these values were significantly higher (58.0% and 22.6% respectively). It was shown that age over 60 years is associated with high risk of complications and mortality after excision of large and giant bulls. In patients <60 years morbidity is comparable after bullectomy and surgical reduction of pulmonary volume. Selection of patients for palliative surgical correction of respiratory failure is generally corresponded to that for lung transplantation. However, these methods should be considered complementary rather competing.

To report the long-term outcome, return to work and owner satisfaction, for working farm dogs in New Zealand following surgical repair of humeral condylar fractures. A retrospective study of working dogs that had undergone surgical repair of one or more condylar fractures of the humerus was undertaken by searching the medical records of two referral veterinary clinics. The inclusion criteria were working dogs that had undergone open surgical reduction and internal fixation of a fracture of one or both humeral condyles. The ability of the dog to work after surgery, persistence of lameness and the owners' degree of satisfaction with the outcome were assessed from answers to a questionnaire. Sixteen dogs met the inclusion criteria and had owner questionnaires completed at a median follow-up interval of 54 (min 3, max 121) months. Fifteen were working farm dogs (13 Heading dogs, including Border Collies, and two New Zealand Huntaways) and one dog was a cross-breed used for pig hunting. Four dogs had two fractures on separate occasions, of which three underwent surgery on both elbows at a median interval of 19 months. Of the 20 humeral fractures, 10 were lateral condylar, one was a medial condylar fracture and nine were dicondylar fractures. Of the 16 repairs with follow-up data, seven (44%) dogs could perform all expected duties following surgical repair, whilst a further eight (50%) could perform most duties although some allowances had to be made for some limitation of their performance. Of the 15 owners responding, 13 (87%) were satisfied or very satisfied with the outcome of surgery and felt the surgery was worth the expense. Post-operative complications requiring a second surgery occurred in 7/20 (35%) dogs, and all six dogs that received appropriate surgical revision returned to work. In this small case series, surgical repair of humeral condylar fractures in working dogs had a good prognosis with 15/16 of treated dogs returning to full or substantial levels of work. These data provide veterinarians with relevant information regarding the outcome and prognosis of surgery for clients whose working dogs have fractured a humeral condyle.

This study applies recent advances in 3D virtual imaging for application in the prediction planning of dentofacial deformities. Stereo-photogrammetry has been used to create virtual and physical models, which are creatively combined in planning the surgical correction of anterior open bite. The application of these novel methods is demonstrated through the surgical correction of a case.

This study reviewed the literature regarding the pros and cons of various surgical approaches (anterior, anterolateral, combined, and posterior) for correction of post-tubercular kyphosis. The anterior and anterolateral approaches are effective in improving neurological deficit but not in correcting kyphosis. The combined anterior and posterior approach and the posterior approach combined with 3-column osteotomy achieve good neurological improvement and kyphosis correction. The latter is superior when expertise and facilities are available.

Pathological (late) fracture of the mandibular angle after third molar surgery is very rare (0.005% of third molar removals). There are 94 cases reported in the literature; cases associated with osseous pathologies such as osteomyelitis or any local and systemic diseases that may compromise mandibular bone strength have not been included. We describe three new cases of pathological (late) fracture of the mandibular angle after third molar surgery. The first patient was a 27-year-old Caucasian man who had undergone surgical removal of a 3.8, mesioangular variety, class II-C third molar 20 days before admission to our clinic. The fracture of his left mandibular angle, complete and composed, occurred during chewing. The second patient was a 32-year-old Caucasian man. He had undergone surgical removal of a 3.8, mesioangular variety, class II-B third molar 22 days before his admission. The fracture, which occurred during mastication, was studied by computed tomography that showed reparative tissue in the fracture site. The third patient was a 36-year-old Caucasian man who had undergone surgical removal of a 3.8, vertical variety, class II-C third molar 25 days before the observation. In this case the fracture of his mandibular angle was oblique (unfavorable), complete and composed. The fracture had occurred during chewing. We studied the fracture by optical projection tomography and computed tomography.All of the surgical removals of the 3.8 third molars, performed by the patients' dentists who had more than 10 years of experience, were difficult. We treated the fractures with open surgical reduction, internal fixation by titanium miniplates and intermaxillary elastic fixation removed after 6 weeks. The literature indicates that the risk of pathological (late) fracture of the mandibular angle after third molar surgery for total inclusions (class II-III, type C) is twice that of partial inclusions due to the necessity of ostectomies more generous than those for partial inclusions. Other important factors are the anatomy of the teeth and the features of the teeth roots. These fractures predominantly occur in patients who are older than 25 years. The highest incidence (67.8% of cases) is found in the second and third week postsurgery. We emphasize that before the third molar surgery it is extremely important to always provide adequate instructions to the patient in order to avoid early masticatory loads and prevent this rare event.

To determine through the measurement of different angles the correction of lumbar hyperlordosis after bilateral femoral lengthening using the Icatme technique and to assess the absence of neurological symptomatology secondary to stenosis of the lumbar canal after femoral lengthening. Thirty-four patients with achondroplasia were studied. Mean age was 22.3 years. The patients underwent femoral lengthening using the Icatme technique. X rays of the lateral rachis taken before and after lengthening were used to measure a series of angles. The lumbar lordosis angle, Sez's angle and the L5S1 angle decreased while the lumbosacral angle, Jungham's angle and the sacrum angle increased, leading to correction of lumbar hyperlordosis, verticalization of the sacrum and improvement in thoracolumbar and lumbosacral inflection. Values were similar to the standard for individuals without achondroplasia. Femoral lengthening using the Icatme technique in achondroplastics modifies the statics of the lumbar spine, making them similar to those of nonachondroplastics. The procedure corrects lumbar hyperlordosis and prevents the appearance of neurological symptomatology due to stenosis of the lumbar canal. The incidence of neurological complications due to stenosis of the lumbar canal in achondroplastics who have undergone femoral lengthening is low compared with that of achondroplastics of the same age and sex who have not undergone this procedure.

Patients with anophthalmic or phthisis socket suffer from cosmetic problems. To resolve those problems, the authors present the surgical outcomes of deep superior sulcus (DSS) augmentation using acellular dermal matrix in patients with anophthalmic or phthisis socket. The authors retrospectively reviewed anophthalmic or phthisis patients who underwent surgery for DSS augmentation using acellular dermal matrix. To evaluate surgical outcomes, the authors focused on 3 aspects: the possibility of wearing contact prosthesis, the degree of correction of the DSS, and any surgical complications. The degree of correction of DSS was classified as excellent: restoration of superior sulcus enough to remove sunken sulcus shadow; fair: gain of correction effect but sunken shadow remained; or fail: no effect of correction at all. Ten eyes of 10 patients were included. There was a mean 21.3 ± 37.1-month period from evisceration or enucleation to the operation for DSS augmentation. All patients could wear contact prosthesis after the operation (100%). The degree of correction was excellent in 8 patients (80%) and fair in 2. Three of 10 (30%) showed complications: eyelid entropion, upper eyelid multiple creases, and spontaneous wound dehiscence followed by inflammation after stitch removal. Uneven skin surface and paresthesia in the forehead area of the affected eye may be observed after surgery. The overall surgical outcomes were favorable, showing an excellent degree of correction of DSS and low surgical complication rates. This procedure is effective for patients who have DSS in the absence or atrophy of the eyeball.

The published return-to-play (RTP) rates for athletes who have undergone surgical repair of superior labrum anterior-posterior (SLAP) tears vary widely and are generally accepted to be lower in the subset of competitive throwers. The efficacy of nonsurgical treatment for this group is unknown. Nonsurgical treatment of SLAP tears in professional baseball players leads to RTP before consideration of surgical treatment. Incorporating performance statistics and level of competition will result in lower calculated RTP rates than have been previously reported. Case series; Level of evidence, 4. A retrospective review of 119 consecutive patients in a single professional baseball organization with persistent shoulder pain that limited the ability to compete was performed. Sixty-eight patients had magnetic resonance imaging-documented SLAP lesions. All patients had failed 1 attempt at rehabilitation but had continued with supervised physical therapy. Treatment was according to an algorithm focusing on the correction of scapular dyskinesia and posterior capsular contracture with glenohumeral internal rotation deficit (GIRD), followed by pain-free return to throwing. Those who failed 2 cycles of nonsurgical treatment were treated surgically. Success was defined by 2 different standards: (1) RTP, in accordance with previous studies; and (2) a more stringent standard of return to the same level/quality of professional competition (A, AA, AAA, etc) with the incorporation of a return to preinjury individual performance statistics (earned run average, walks plus hits per inning pitched), termed "return to prior performance" (RPP). Sixty-eight athletes were identified with SLAP lesions. Twenty-one pitchers successfully completed the nonsurgical algorithm and attempted a return. Their RTP rate was 40%, and their RPP rate was 22%. The RTP rate for 27 pitchers who underwent 30 procedures was 48%, and the RPP rate was 7%. For 10 position players treated nonsurgically, the RTP rate was 39%, and the RPP rate was 26%. The RTP rate for 13 position players who underwent 15 procedures was 85%, with an RPP rate of 54%. Nonsurgical treatment correcting scapular dyskinesia and GIRD had a reasonable success rate in professional baseball players with painful shoulders and documented SLAP lesions. The rate of return after surgical treatment of SLAP lesions was low for pitchers. The RTP and RPP rates were higher for position players than for pitchers. Nonsurgical treatment should be considered for professional baseball players with documented SLAP lesions, as it can lead to acceptable RTP and RPP rates.

A Nurse-Initiated Perioperative Pressure Injury Risk Assessment and Prevention Protocol.

Pressure injuries negatively affect patients physically, emotionally, and economically. Studies report that pressure injuries occur in 69% of inpatients who have undergone a surgical procedure while hospitalized. In 2012, we created a nurse-initiated, perioperative pressure injury risk assessment measure for our midwestern, urban, adult teaching hospital. We retrospectively applied the risk assessment to a random sample of 350 surgical patients which validated the measure. The prospective use of the risk assessment and prevention measures in 350 surgical patients resulted in a 60% reduction in pressure injuries compared with the retrospective group. Our findings support the use of a multipronged approach for the prevention of health care-associated pressure injuries in the surgical population, which includes assessment of risk, implementation of evidence-based prevention interventions for at-risk patients, and continuation of prevention beyond the perioperative setting to the nursing care unit.

To explore the potential association between reduced corneal sensation and/or conjunctival bacterial colonization and postoperative trichiasis and eyelid contour abnormalities after corrective eyelid surgery among participants with a history of trachomatous trichiasis. As an ancillary study to the Partnership for Rapid Elimination of Trachoma (PRET) Surgery Trial in southern Tanzania, we collected data on 580 PRET participants who had undergone trichiasis surgery 1 year earlier and 200 age-group-matched individuals without trichiasis. Assessments included eyelid status evaluation (presence and severity of postoperative trichiasis and/or eyelid contour abnormality), corneal sensitivity by Cochet-Bonnet aesthesiometer, a questionnaire on symptoms of ocular irritation, and conjunctival microbiology. We divided PRET participants based on their eyelid status and compared results across PRET groups and versus normals. PRET participants had reduced corneal sensitivity compared with age-matched normals (mean sensitivity ranged from 2.8 to 3.8 cm in PRET participants vs. 5.9 cm in normals), and increasing severity of postoperative trichiasis was associated in a stepwise fashion with reduced corneal sensitivity (mean = 3.5 cm for mild and 2.6 cm for severe postoperative trichiasis). Conjunctival colonization with pathogenic bacteria was also associated with more severe postoperative trichiasis (Cochran-Armitage trend test P = 0.001) and with reduced corneal sensitivity (trend test P < 0.0001). Symptoms of ocular irritation were not associated with previous trichiasis surgery, postoperative trichiasis, or eyelid contour abnormality. These findings indicate that reduced corneal sensitivity accompanies trachomatous trichiasis and suggest that reduced corneal sensitivity may play an important role in the harboring of pathogenic bacteria on the ocular surface.

OBJECTIVE Anterior capsulotomy (AC) is sometimes used as a last resort for treatment-refractory obsessive-compulsive disorder (OCD). Previous studies assessing neuropsychological outcomes in patients with OCD have identified several forms of cognitive dysfunction that are associated with the disease, but few have focused on changes in cognitive function in OCD patients who have undergone surgery. In the present study, the authors investigated the effects of AC on the cognitive function of patients with treatment-refractory OCD. METHODS The authors selected 14 patients with treatment-refractory OCD who had undergone bilateral AC between 2007 and 2013, 14 nonsurgically treated OCD patients, and 14 healthy control subjects for this study. The 3 groups were matched for sex, age, and education. Several neuropsychological tests, including Similarities and Block Design, which are subsets of the Wechsler Abbreviated Scale of Intelligence; Immediate and Delayed Logical Memory and Immediate and Delayed Visual Reproduction, which are subsets of the Wechsler Memory Scale-Revised; and Corrects, Categories, Perseverative Errors, Nonperseverative Errors, and Errors, subtests of the Wisconsin Card Sorting Test, were conducted in all 42 subjects at baseline and after AC, after nonsurgical treatment, or at 6-month intervals, as appropriate. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to measure OCD symptoms in all 28 OCD patients. RESULTS The Y-BOCS scores decreased significantly in both OCD groups during the 12-month follow-up period. Surgical patients showed higher levels of improvement in verbal memory, visual memory, visuospatial skills, and executive function than the nonsurgically treated OCD patients. CONCLUSIONS The findings of this study suggest that AC not only reduces OCD symptoms but also attenuates moderate cognitive deficits.

Success of torsional correction surgery after failed surgeries for patellofemoral pain and instability.

Torsional deformities of the femur and/or tibia often go unrecognized in adolescents and adults who present with anterior knee pain, and patellar maltracking or instability. While open and arthroscopic surgical techniques have evolved to address these problems, unrecognized torsion may compromise the outcomes of these procedures. We collected a group of 16 consecutive patients (23 knees), with mean age of 17, who had undergone knee surgery before torsion was recognized and subsequently treated by means of rotational osteotomy of the tibia and/or femur. By follow-up questionnaire, we sought to determine the role of rotational correction at mean 59-month follow-up. We reasoned that, by correcting torsional alignment, we might be able to optimize long-term outcomes and avert repeated knee surgery. Knee pain was significantly improved after torsional treatment (mean 8.6 pre-op vs. 3.3 post-op, p < 0.001), while 70 % of patients did have some continued knee pain postoperatively. Only 43 % of patients had continued patellar instability, and 57 % could trust their knee after surgery. Activity level remained the same or increased in 78 % of patients after torsional treatment. Excluding planned rod removal, subsequent knee surgery for continued anterior knee pain was undertaken on only 3 knees in 2 patients. We believe that malrotation of the lower limb not only raises the propensity for anterior knee symptoms, but is also a under-recognized etiology in the failure of surgeries for anterior knee pain and patellar instability. Addressing rotational abnormalities in the index surgery yields better clinical outcomes than osteotomies performed after other prior knee surgeries.

To establish some guidelines for the definition, diagnosis, and treatment of failed posterior urethroplasty. We identified 20 successive patients who required a secondary endoscopic or surgical procedure after anastomotic repair of a postpelvic fracture urethral injury from 1979 to 2010. Of the 20 patients, 18 had undergone perineal repair and 2 a perineo-abdominal procedure. Their medical records were reviewed with a focus on 6 postoperative items: symptoms, onset of unsuccessful result, urethral calibration, urethrocystography, urethroscopy, and treatment. Follow-up ranged from 1 to 25 years (mean 14). Of the 20 patients, 11 (55%) presented shortly after removal of the urethral stent with failure to void (n = 9) or incontinence (n = 2), and 9 (45%) presented 1 month to 12 years after surgery with a weak stream. Early failures resulted from obstruction at the site of repair in 5 patients, retraction of the bulbar urethra in 3, wrong anastomosis to a false tract in 1, and an open bladder neck in 2. Correction was accomplished by salvage urethroplasty in 8 patients and bladder neck repair in 2. Late failures resulted from narrowing of the anastomosis and were corrected by direct visual internal urethrotomy in 7 patients and surgery in 2. Unsuccessful outcomes can be encountered shortly after removal of the urethral stent or delayed for several months or years after surgery. Early cases present by an inability to void or incontinence and usually require salvage urethroplasty or bladder neck repair. Late cases present by a weak urinary stream, are due to narrowing of the anastomosis, and are usually corrected by direct visual internal urethrotomy. Copyright © 2012 Elsevier Inc.

Surgical education is changing rapidly as several factors including budget constraints and medicolegal concerns limit opportunities for urological trainees. New methods of skills training such as low fidelity bench trainers and virtual reality simulators offer new avenues for surgical education. In addition, surgical simulation has the potential to allow practicing surgeons to develop new skills and maintain those they already possess. We provide a review of the background, current status and future directions of surgical simulators as they pertain to urology. We performed a literature review and an overview of surgical simulation in urology. Surgical simulators are in various stages of development and validation. Several simulators have undergone extensive validation studies and are in use in surgical curricula. While virtual reality simulators offer the potential to more closely mimic reality and present entire operations, low fidelity simulators remain useful in skills training, particularly for novices and junior trainees. Surgical simulation remains in its infancy. However, the potential to shorten learning curves for difficult techniques and practice surgery without risk to patients continues to drive the development of increasingly more advanced and realistic models. Surgical simulation is an exciting area of surgical education. The future is bright as advancements in computing and graphical capabilities offer new innovations in simulator technology. Simulators must continue to undergo rigorous validation studies to ensure that time spent by trainees on bench trainers and virtual reality simulators will translate into improved surgical skills in the operating room.

Aims To investigate the histological evolution in the development of pleuroparenchymal fibroelastosis (PPFE). Methods and results We examined four patients who had undergone surgical lung biopsy twice, or who had undergone surgical lung biopsy and had been autopsied, and in whom the histological diagnosis of the first biopsy was not PPFE, but the diagnosis of the second biopsy or of the autopsy was PPFE. The histological patterns of the first biopsy were cellular and fibrotic interstitial pneumonia, cellular interstitial pneumonia (CIP) with organizing pneumonia, CIP with granulomas and acute lung injury in cases 1, 2, 3, and 4, respectively. Septal elastosis was already present in the non-specific interstitial pneumonia-like histology of case 1, but a few additional years were necessary to reach consolidated subpleural fibroelastosis. In case 3, subpleural fibroelastosis was already present in the first biopsy, but only to a small extent. Twelve years later, it was replaced by a long band of fibroelastosis. The septal inflammation and fibrosis and airspace organization observed in the first biopsies were replaced by less cellular subpleural fibroelastosis within 3–12 years. Conclusions Interstitial inflammation or acute lung injury may be an initial step in the development of PPFE. PMID:25234959

The place of laparoscopic repair of perforated peptic ulcer followed by peritoneal toilet has been established, although it is not routinely practiced. This prospective study compared laparoscopic and open repair of perforated peptic ulcer disease. We evaluated whether the early results from laparoscopic repair resulted in improved patient outcome compared with conventional open repair. All patients who underwent repair of perforated peptic ulcer disease during a 12-month period in our unit were included in the study. The primary end points that were evaluated were total operative time, nasogastric tube utilisation, intravenous fluid requirement, total time of urinary catheter and abdominal drainage usage, time taken to return to normal diet, intravenous/intramuscular opiate use, time to full mobilization, and total in-patient hospital stay. Thirty-three patients underwent surgical repair of perforated peptic ulcer disease (19 laparoscopic repairs and 14 open repairs; mean age, 54.2 (range, 32-82) years). There was no increase in total operative time in patients who had undergone laparoscopic repair (mean: 61 minutes laparoscopic versus 57 minutes open). There was significantly less requirement for intravenous/intramuscular opiate analgesia in patients who had undergone laparoscopic repair (mean time to oral analgesia: 1.2 days laparoscopic versus 3.8 days open). In addition there was a significant decrease in the time that the nasogastric tube (mean: 2.1 days laparoscopic versus 3.1 days open), urinary catheter (mean: 2.3 days laparoscopic versus 3.7 days open) and abdominal drain (mean: 2.2 days laparoscopic versus 3.8 days open) were required during the postoperative period. Patients who had undergone laparoscopic repair required less intravenous fluids (mean: 1.4 days laparoscopic versus 3.1 days open) and returned to normal diet (mean: 2.3 days laparoscopic versus 4.8 days open) and full mobilization significantly earlier than those who had undergone open repair (mean: 2.3 days laparoscopic versus 3.3 days open). In addition, patients who had undergone laparoscopic repair required a shorter in-patient hospital stay (mean: 3.1 days laparoscopic versus 4.3 days open). Laparoscopic repair is a viable and safe surgical option for patients with perforated peptic ulcer disease and should be considered for all patients, providing that the necessary expertise is available.

Contemporary Medical and Surgical Management of X-linked Hypophosphatemic Rickets.

X-linked hypophosphatemia is an inheritable disorder of renal phosphate wasting that clinically manifests with rachitic bone pathology. X-linked hypophosphatemia is frequently misdiagnosed and mismanaged. Optimized medical therapy is the cornerstone of treatment. Even with ideal medical management, progressive bony deformity may develop in some children and adults. Medical treatment is paramount to the success of orthopaedic surgical procedures in both children and adults with X-linked hypophosphatemia. Successful correction of complex, multiapical bone deformities found in patients with X-linked hypophosphatemia is possible with careful surgical planning and exacting surgical technique. Multiple methods of deformity correction are used, including acute and gradual correction. Treatment of some pediatric bony deformity with guided growth techniques may be possible.

2016-01-01

To identify the anatomy and pathology of chest wall malformations presenting for consideration for corrective surgery or as a possible chest wall “mass”, and to review the common corrective surgical procedures. Congenital chest wall deformities are caused by anomalies of chest wall growth, leading to sternal depression or protrusion, or are related to failure of normal spine or rib development. Cross-sectional imaging allows appreciation not only of the involved structures but also assessment of the degree of displacement or deformity of adjacent but otherwise normal structures and differentiation between anatomical deformity and neoplasia. In some cases, CT is also useful for surgical planning. The use of three-dimensional reconstructions, utilizing a low-dose technique, provides important information for the surgeon to discuss the nature of anatomical abnormalities and planned corrections with the patient and often with their parents. In this pictorial essay, we discuss the radiological features of the commonest congenital chest wall deformities and illustrate pre- and post-surgical appearances for those undergoing surgical correction.

Although achalasia presents with typical symptoms such as dysphagia, regurgitation, weight loss, and atypical chest pain, the time until first diagnosis often takes years and is frustrating for patients and nevertheless associated with high costs for the healthcare system. A total of 563 patients were interviewed with confirmed diagnosis of achalasia regarding their symptoms leading to diagnosis along with past clinical examinations and treatments. Included were patients who had undergone their medical investigations in Germany. Overall, 527 study subjects were included (male 46%, female 54%, mean age at time of interview 51 ± 14.8 years). Dysphagia was present in 86.7%, regurgitation in 82.9%, atypical chest pain in 79%, and weight loss in 58% of patients before diagnosis. On average, it took 25 months (Interquartile Range (IQR) 9-65) until confirmation of correct diagnosis of achalasia. Though, diagnosis was confirmed significantly quicker (35 months IQR 9-89 vs. 20 months IQR 8-53; p < 0.01) in the past 15 years. The majority (72.1%) was transferred to three or more specialists. Almost each patient underwent at least one esophagogastroduodenoscopy (94.2%) and one radiological assessment (89.3%). However, esophageal manometry was performed in 70.4% of patients only. The severity of symptoms was independent with regard to duration until first diagnosis (Eckardt score 7.14 ± 2.64 within 12 months vs. 7.29 ± 2.61 longer than 12 months; P = 0.544). Fifty-five percent of the patients primarily underwent endoscopic dilatation and 37% a surgical myotomy. Endoscopic dilatation was realized significantly faster compared to esophageal myotomy (1 month IQR 0-4 vs. 3 months IQR 1-11; p < 0.001). Although diagnosis of achalasia was significantly faster in the past 15 years, it still takes almost 2 years until the correct diagnosis of achalasia is confirmed. Alarming is the fact that although esophageal manometry is known as the gold standard to differentiate primary motility disorders, only three out of four patients had undergone this diagnostic pathway during their diagnostic work-up. Better education of medical professionals and broader utilization of highly sensitive diagnostic tools, such as high-resolution manometry, are strictly necessary in order to correctly diagnose affected patients and to offer therapy faster. © The Authors 2017.

For aesthetic purposes, we performed intrastromal keratopigmentation surgery using ink for skin tattoos supplied in sterile single-dose vessels. No secondary effects or complications were observed. Keratopigmentation or corneal tattooing can now be used as a last resort in patients who are unable to tolerate cosmetic contact or intraocular lenses, or in whom corneal transplant is contraindicated.

Correction of the protruded lobule in otoplasty continues to represent an important challenge. The lack of skeletal elements within the lobule makes a controlled lobule repositioning less predictable. OBJECTIVE To present a new surgical technique for lobule correction in otoplasty. Human cadaver studies were performed for detailed anatomical analysis of lobule deformities. In addition, we evaluated a novel algorithmic approach to correction of the lobule in 12 consecutive patients. INTERVENTIONS/EXPOSURES: Otoplasty with surgical correction of lobule using the fillet technique. The surgical outcome in the 12 most recent consecutive patients with at least 3 months of follow-up was assessed retrospectively. The postsurgical results were independently reviewed by a panel of noninvolved experts. The 3 major anatomic components of lobular deformities are the axial angular protrusion, the coronal angular protrusion, and the inherent shape. The fillet technique described in the present report addressed all 3 aspects in an effective way. Clinical data analysis revealed no immediate or long-term complications associated with this new surgical method. The patients' subjective rating and the panel's objective rating revealed "good" to "very good" postoperative results. This newly described fillet technique represents a safe and efficient method to correct protruded ear lobules in otoplasty. It allows precise and predictable positioning of the lobule with an excellent safety profile. 4.

Although there is a growing body of evidence to document the safety and efficacy of operative treatment of carotid stenosis, surgical indications for elongation and kinking of the internal carotid artery remain controversial. The goal of this study was to evaluate the efficacy of surgical correction of internal carotid artery kinking in patients with persistent hemispheric symptoms despite antiplatelet therapy. A consecutive series of 81 patients (mean age, 64 years) underwent 83 surgical procedures to correct kinking of the internal carotid artery either by shortening and reimplanting the vessel on the common carotid artery, inserting a bypass graft, or transposing the vessel onto the external carotid artery. Mean follow-up was 56 months (range, 15-135 months). Study endpoints were 30-day mortality and any stroke occurring during follow-up. No postoperative death was observed. The postoperative stroke rate was 1%. Primary patency, freedom from neurologic symptoms, and late survival at 5 years (x +/- standard deviation) were 89 +/- 4.1%, 92 +/- 4%, and 71 +/- 6%, respectively. The findings of this study indicate that surgical correction for symptomatic stenotic kinking of the internal carotid artery is safe and effective in relieving symptoms and preventing stroke. Operative correction should be considered as the standard treatment for patients with symptomatic carotid kinking that does not respond to antiplatelet therapy.

Determine the occurrence of dysphagia symptoms in children with cleft lip and/or palate (CLP) pre- and post-surgical correction. Quantitative observational cross-sectional study. Existence of clef lip and/or palate without association with other syndromes was the study inclusion and/or exclusion criterion. Parents and/or legal guardians responded to a recall questionnaire on the identification of occurrence of coughing, choking, vomiting, and nasal escape pre- and postoperatively and whether these symptoms disappeared after surgical correction. The study was approved by the Research Ethics Committee of the aforementioned Institution under protocol no. 1573164. The sample comprised 23 children with mean age of 48 months, mostly male and with unilateral trans-foramen incisor clefts. Statistically significant difference was observed between the pre- and post-surgical periods regarding the presence of dysphagia symptoms. Surgical treatment of patients with cleft lip and/or palate proved to be a resource to prevent the occurrence of dysphagia symptoms when associated with adequate intervention chronology.

In total surgical correction of tetralogy of Fallot (TOF) with functioning Blalock Taussig shunts (BTS), shunt take down increased surgical time, bleeding, and might injure phrenic and recurrent laryngeal nerve and thoracic duct. A routine hybrid approach using transcatheter BTS closure immediately before total surgical correction of TOF in all patients might reduce these problems. We analyze the safety and feasibility of this approach. Transcatheter BTS closure was achieved using single or multiple stainless steel embolization coils, Amplatzer vascular plugs, or duct occluders. When coils were released without control by bioptome forceps, coil migration in larger shunts was prevented by proximal or distal balloon occlusion. This routine hybrid strategy was followed in 22 consecutive patients aged 1-13 years over 4-year-period and 21 procedures were successful. Among the 16 patients attempted with coils, 13 had successful closure, 2 needed Amplatzer duct occluder devices, and 1 sent for surgical shunt takedown due to acute angulation of the shunt. New Amplatzer vascular plugs were used in six patients. Bioptome was used in six patients and proximal or distal balloon occlusion of flow was used in three patients. Four patients had closure of associated aortopulmonary or chest wall collaterals. Hybrid approach using routine transcatheter closure of all BTS immediately before surgical correction of TOF shunts with coils/plugs/devices is safe, feasible, and reproducible.

Ankylosing tuberculosis is an infection caused by Mycobacterium tuberculosis in one or more components of the vertebrae; it is Pott disease or tuberculous spondylitis. It might become a potential cause of morbidity, including neurological deficits and permanent deformity of the spine. Management of TB Spondylitis, in general, is chemotherapy with antituberculosis drugs (ATG), immobilization, and spine surgical interventions. A retrospective study was conducted to analyze the patients of TB Spondylitis who had undergone surgery at Haji Adam Malik hospital from June 2015 to June 2017. The most common location is thoracal (10%), lumbal (3%), and thoracolumbal junction (3%). Decompression laminectomy with fusion (18%) is the most suitable option for surgical management. The majority, pre- operation ASIA scale is D (8%), and post operation is E (8%). It means that surgical plays an important role in themanagement of tuberculous spondylitis.

Surgeons may be unaware of the ability of plant toxins to cause corneal damage. Therefore, corneal damage following intraocular surgery due to plant toxins may be misdiagnosed as postoperative infection. A 74-year-old man presented with hyperemia and reduced visual acuity in both eyes 6 weeks after uneventful cataract surgery. We observed extensive hyperemia and corneal stromal edema with Descemet's folds in both eyes. After obtaining a detailed patient history, we diagnosed plant toxin-induced corneal edema due to Asclepias physocarpa, which can induce corneal edema by inhibiting the Na + /K + ATPase activity of the corneal endothelium. Antimicrobial and steroid eye drops and an oral steroid were prescribed accordingly. Symptons began to improve on day 3 and had almost completely resolved by day 6. At 1 month, the patient had fully recovered without any sequelae. The correct diagnosis was possible in the present case as symptoms were bilateral and the patient was able to report his potential exposure to plant toxins. However, if the symptoms had been unilateral and the patient had been unaware of these toxins, he may have undergone unnecessary surgical interventions to treat non-existent postoperative endophthalmitis.

A retrospective study of patients who underwent gastrocnemius recession, double calcaneal osteotomy (Evans osteotomy and percutaneous calcaneal displacement osteotomy), and medial column fusion for the treatment of posterior tibial tendon dysfunction was conducted. The senior author performed the procedures between November 2002 and January 2009 on 34 patients who displayed at least Johnson and Strom stage II deformity and had undergone 12 months of failed conservative treatment. The coauthors evaluated the patients' radiographs before and after the operation. At a mean of 14 (range 3 to 44) months after surgery, radiographic measurements demonstrated statistically significant changes in the structural alignment of the feet. Based on our experience with these patients, we believe that a double calcaneal osteotomy combined with a gastrocnemius recession and stabilization of the medial column for the treatment of posterior tibial tendon dysfunction provides satisfactory correction, stability, and realignment of the foot. Furthermore, we feel that the use of flexor digitorum longus transfer, as well as triple arthrodesis, can be avoided without compromising the outcome when surgically treating posterior tibial tendon dysfunction.

In 1987 the Swedish Dental Act was amended to allow Swedish dentists who have undergone a specific accreditation course to administer intra-venous sedation. Midazolam is a benzodiazepin derivate with express sedative and hypnotic qualities, powerful amnesia, a short half-life time and few secondary effects. From 1989-1994 midazolam intravenous conscious sedation (ICS) was administered in 372 cases in the Department of Oral and Maxillofacial Surgery, County Hospital, Falun. This study presents data on the 298 patients. Although surgical removal of impacted wisdom teeth predominated, implant surgery, reduction of fractures and correction of anomalies were also carried out. Supplementary sedative premedication was rarely used. Most patients were treated under local anaesthesia. The mean dosage was 10.45 mg (range 1.25-40 mg). Mean dosage/kg was 0.15 mg (range 0.03-0.50 mg). The average duration of anaesthesia was 50 minutes. The average recovery time was 94 minutes. Three hundred and sixty-nine of 372 planned treatments were completed. No serious complications occurred. The patients were co-operative during surgery and were satisfied with the treatment. Compared with full anaesthesia this method required less resources and is a valuable complement in management of anxious patients undergoing oral surgery.

Cryptotia is a congenital auricular deformity in which the upper third of the auricle is buried under the temporal skin. There is no standard surgical method to correct cryptotia. This study is aimed at devising a new surgical method to correct cryptotia with good auricular contour and inconspicuous scar. We retrospectively reviewed 8 patients diagnosed with cryptotia in West China Hospital between 2006 and 2009. All of them received this new surgical method to correct cryptotia. The follow-up period ranged from 6 months to 1 year. All patients possessed good auricular contour and sufficient skin for release of the upper part of the auricle without the need for a skin graft or local skin flap transferred. All patients possessed deep auriculotemporal sulci and inconspicuous scars. There were no complications, and cryptotia did not recur in any patient.

Mesenteric ischemia and ischemic colitis are uncommon but potentially life-threatening causes of acute abdominal pain. Portal venous phase computed tomography (CT) is routinely ordered in the emergency room setting for abdominal pain, but subsequent MR angiography may be requested for additional evaluation of the mesenteric vasculature. We compare the concordance of CT and magnetic resonance angiography (MRA) for acute bowel ischemia. Thirty-two patients who underwent contrast-enhanced MRA for bowel ischemia after having undergone CT evaluation within the preceding 2 weeks were identified. A retrospective review of imaging, treatment history, surgical, and pathology reports was conducted. Two radiologists each reviewed the imaging studies in a blinded fashion. Ten cases of bowel ischemia were confirmed by endoscopy and/or surgical pathology. CT correctly identified bowel findings in all cases. Intraobserver agreement between CT and MRA for all vessels was 0.68 and 0.63, highest for the superior mesenteric artery. Interobserver agreement was 0.74 for MRA and 0.78 for CT. Vascular findings were only directly mentioned in 10 of 32 CT reports (and 7 of 10 cases with confirmed bowel ischemia). MRA only detected two additional or alternative diagnoses. Portal venous phase CT and MRA demonstrate a high degree of concordance for vascular evaluation. Reviewed CT examinations were sufficient to assess the patency of the mesenteric vasculature, but vascular findings were not reported in most cases. A direct description within the report may have obviated the request for further MR imaging. MRA adds little value after portal venous CT in assessing bowel ischemia.

Since the creation of SynCardia's 50 cc Total Artificial Hearts (TAHs), patients with irreversible biventricular failure now have two sizing options. Herein, a case series of three patients who have undergone successful 50 and 70 cc TAH implantation with complete closure of the chest cavity utilizing preoperative "virtual implantation" of different sized devices for surgical planning are presented. Computed tomography (CT) images were used for preoperative planning prior to TAH implantation. Three-dimensional (3D) reconstructions of preoperative chest CT images were generated and both 50 and 70 cc TAHs were virtually implanted into patients' thoracic cavities. During the simulation, the TAHs were projected over the native hearts in a similar position to the actual implantation, and the relationship between the devices and the atria, ventricles, chest wall, and diaphragm were assessed. The 3D reconstructed images and virtual modeling were used to simulate and determine for each patient if the 50 or 70 cc TAH would have a higher likelihood of successful implantation without complications. Subsequently, all three patients received clinical implants of the properly sized TAH based on virtual modeling, and their chest cavities were fully closed. This virtual implantation increases our confidence that the selected TAH will better fit within the thoracic cavity allowing for improved surgical outcome. Clinical implantation of the TAHs showed that our virtual modeling was an effective method for determining the correct fit and sizing of 50 and 70 cc TAHs. © 2016 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

During 2013, the Maryland Department of Health and Mental Hygiene in Baltimore, MD, USA, received report of 2 Maryland residents whose surgical sites were infected with rapidly growing mycobacteria after cosmetic procedures at a clinic (clinic A) in the Dominican Republic. A multistate investigation was initiated; a probable case was defined as a surgical site infection unresponsive to therapy in a patient who had undergone cosmetic surgery in the Dominican Republic. We identified 21 case-patients in 6 states who had surgery in 1 of 5 Dominican Republic clinics; 13 (62%) had surgery at clinic A. Isolates from 12 (92%) of those patients were culture-positive for Mycobacterium abscessus complex. Of 9 clinic A case-patients with available data, all required therapeutic surgical intervention, 8 (92%) were hospitalized, and 7 (78%) required ≥3 months of antibacterial drug therapy. Healthcare providers should consider infection with rapidly growing mycobacteria in patients who have surgical site infections unresponsive to standard treatment. PMID:27434822

The literature discussing the impact of a single Le Fort I osteotomy on nasopharyngeal airways is limited. This study assessed the volumetric changes in the nasopharyngeal airway after a single Le Fort I osteotomy and explored the correlation between these changes and 3-dimensional surgical movements of the upper jaw. This retrospective study was conducted in 40 patients who had undergone a single Le Fort I (maxillary advancement with or without impaction) to correct Class III malocclusion with maxillary hypoplasia. Preoperative (T1) and 6-month postoperative (T2) cone-beam computed tomographic (CBCT) scans of these patients were used for analysis. Maxillary surgical movements and volumetric changes in the nasopharyngeal airway were measured. The reproducibility of the measurements was evaluated using paired t tests and intraclass correlation coefficients. The Wilcoxon test and Pearson correlation coefficient were applied to evaluate the volumetric changes in the nasopharyngeal airway space and assess the correlations of these changes to the maxillary surgical movements. Six patients were excluded from the study owing to major differences (>5°) in their head and neck posture between the T1 and T2 CBCT scans. The errors of the repeated measurements were insignificant (P > .05), with a high level of agreement (r = 0.99; P < .05) between the repeated digitization of the landmarks. There was a statistically significant impact of a Le Fort I osteotomy on the right maxillary sinus (decreased by 17.8%) and the lower retropalatal space (expanded by 17.3%; P < .05). The correlation between the change in airway volume and the magnitude of surgical maxillary movements was moderate (r = .4). Similarly, there was a moderate correlation between changes in the upper nasopharynx and those in the hypopharynx. The single Le Fort I osteotomy was found to increase the retroglossal airway volume. This could be important for the treatment of obstructive sleep apnea in patients with maxillary deficiency. A long-term follow-up assessment of a larger sample with a functional assessment of airway would be beneficial to confirm these findings.

The purpose of this article is to summarize the work and pioneering achievements in the field of orthopedic surgery of the German orthopedic surgeon Karl Ludloff. Ludloff had an impact in the diagnostics, physical examination, orthopedic imaging, and orthopedic surgical technique of his era. He was a pioneer in the surgical treatment of dysplastic hip, anterior cruciate ligament reconstruction, and hallux valgus. His surgical technique for the correction of hallux valgus, initially stabilized with plaster of Paris, remained unpopular among other orthopedic surgeons for decades. In the 1990s, the advent and use of improved orthopedic materials for fixation attracted the interest of numerous orthopedic surgeons in the Ludloff osteotomy for its ability to correct the deformity in all 3 dimensions, its anatomic outcomes, and its low recurrence rate and patient satisfaction.

In this study, we examined differences in inpatient costs, length of stay, and in-hospital mortality between hospitalizations for patients with and without sickle cell disease (SCD) undergoing high-volume surgical procedures. We used Clinical Classification Software (CCS) codes to identify discharges in the 2002–2005 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project for patients who had undergone either cholecystectomy or hip replacement. We limited the non-SCD cohort to hospitals where patients with SCD had undergone the same procedure. We compared inpatient outcomes using summary statistics and generalized linear regression analysis to adjust for patient, hospital, and procedural characteristics. Overall, the median age of surgical patients with SCD was more than 3 decades less than the median age of patients without SCD undergoing the same procedure. In recognition of the age disparity, we limited the analyses to patients aged 18 to 64 years. Nonetheless, patients with SCD undergoing cholecystectomy or hip replacement were 12.1 and 14.4 years younger, had inpatient stays that were 73% and 82% longer, and incurred costs that were 46% and 40% higher per discharge than patients without SCD, respectively. Inpatient mortality for these procedures was low, approximately 0.6% for cholecystectomy and 0.2% for hip replacement, and did not differ significantly between patients with and without SCD. Multivariable regression analyses revealed that higher inpatient costs among patients with SCD were primarily attributable to longer hospital stays. Patients with SCD who underwent cholecystectomy or hip replacement required more health care resources than patients without SCD. PMID:19787790

Are there residual deficits in balance, mobility, and gaze stability after surgical removal of vestibular schwannoma? Observational study. Twelve people with a mean age of 52 years who had undergone surgical removal of vestibular schwannoma at least three months previously and had not undergone vestibular rehabilitation. Twelve age- and gender-matched healthy people who acted as controls. Handicap due to dizziness, balance, mobility, and gaze stability was measured. Handicap due to dizziness was moderate for the clinical group. They swayed significantly more than the controls in comfortable stance: firm surface eyes open and visual conflict (p < 0.05); foam surface eyes closed (p < 0.05) and visual conflict (p < 0.05); and feet together: firm surface, eyes closed (p < 0.05), foam surface, eyes open (p < 0.05) and eyes closed (p < 0.01). They displayed a higher rate of failure for timed stance and gaze stability (p < 0.05) than the controls. Step Test (p < 0.01), Tandem Walk Test (p < 0.05) and Dynamic Gait Index (p < 0.01) scores were also significantly reduced compared with controls. There was a significant correlation between handicap due to dizziness and the inability to maintain balance in single limb and tandem stance (r = 0.68, p = 0.02) and the ability to maintain gaze stability during passive head movement (r = 0.78; p = 0.02). A prospective study is required to evaluate vestibular rehabilitation to ameliorate dizziness and to improve balance, mobility, and gaze stability for this clinical group.

The optimal type of surgical management for isolated sagittal synostosis remains a source of significant debate. There is a paucity of data regarding possible differences in long-term neuropsychological outcomes following treatment with whole-vault cranioplasty or endoscopic strip craniectomy. This study provides the first comparative analysis examining the effects of the two techniques related to long-term intellectual functioning. A total of 70 patients were enrolled in this multicenter study, 29 of whom had previously undergone endoscopic strip craniectomy and 41 of whom had previously undergone whole-vault cranioplasty. All patients completed a battery of neurodevelopmental tests (Beery-Buktenica Developmental Test of Visual-Motor Integration, Wechsler Abbreviated Scale of Intelligence, and Wechsler Fundamentals) to evaluate various domains of neuropsychological function. In a group comparison of those treated before 6 months of age, whole-vault patients obtained higher scores relative to endoscopic strip craniectomy patients on visuomotor integration, full-scale intelligence quotient, verbal intelligence quotient, word reading, and reading comprehension (p < 0.05 for all). When compared against strip craniectomy performed before 3 months of age, the whole-vault group still showed significantly higher scores in verbal intelligence quotient, reading comprehension, and word reading (p < 0.05 for all). The type of surgical intervention for isolated sagittal synostosis impacts long-term neuropsychological outcomes. Patients undergoing early whole-vault cranioplasty attained higher intelligence quotient and achievement scores relative to those undergoing strip craniectomy. Surgical management with whole-vault cranioplasty performed before 6 months of age provides the most favorable long-term intellectual outcomes in patients with isolated sagittal synostosis.

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Surgical correction of the congenital completely buried penis (CCBP) is a difficult challenge and there is no unanimous consensus about the surgical 'gold standard' and patient eligibility for surgery. In the present study, dysgenetic fundiform ligaments were found to be attached to the distal or middle shaft of the penis. This abnormality can be successfully corrected by releasing the fundiform ligament and mobilising the scrotal skin to cover the length of the penile shaft. The study shows that the paucity and traction of the penile skin and an abnormal fundiform ligament are important anatomical defects in CCBP. Dorsal curve and severe shortage of penile skin in erectile conditions are the main indications for surgical correction. To present our experience of anatomical findings for congenital completely buried penis (CCBP), which has no unanimous consensus regarding the 'gold standard' for surgical correction and patient eligibility, by providing our surgical technique and illustrations. Between February 2006 and February 2011, 22 children with a median (range) age of 4.2 (2.5-5.8) years, with CCBP underwent surgical correction by one surgeon. Toilet training and photographs of morning erections by parents were advised before surgery. The abnormal anatomical structure of buried penis during the operation was observed. The technique consisted of the release of the fundiform ligament, fixation of the subcutaneous penile skin at the base of the degloved penis, penoscrotal Z-plasty and mobilisation of the penile and scrotal skin to cover the penile shaft. In reflex erectile conditions, CCBP presents varying degrees of dorsal curve and shortage of penile skin. Dysgenetic fundiform ligaments were found to be attached to the distal or middle shaft of the penis in all patients. All wounds healed well and the cosmetic outcome was good at 6-month follow-up after the repair. The appearance of the dorsal curve in CCBP mainly results from the traction of penile dorsal skin and the abnormal attachment of the fundiform ligament to the shaft. This abnormality can be successfully corrected by releasing the abnormal fundiform ligament and mobilising scrotal skin to cover the length of the penile shaft. © 2013 BJU International.

Neck dissection is an important treatment for metastases from upper aerodigestive carcinoma; an event that markedly reduces survival. Since its inception, the philosophy of the procedure has undergone significant change from one of radicalism to the current conservative approach. Furthermore, nonsurgical modalities have been introduced, and, in many situations, have supplanted neck surgery. The refinements of imaging the neck based on the concept of neck level involvement has encouraged new philosophies to evolve that seem to benefit patient outcomes particularly as this relates to diminished morbidity. The purpose of this review was to highlight the new paradigms for surgical removal of neck metastases using an evidence-based approach. PMID:24623715

"Buried penis" is an increasing burden in our population with many possible etiologies. Although surgical correction of buried penis can be rewarding and successful for the surgeon, the psychological and functional impact of buried penis on the patient is less understood. The study's aim was to evaluate the sexual satisfaction and overall quality of life before and after buried penis surgery in a single-surgeon's patient population using a validated questionnaire (Changes in Sexual Functioning Questionnaire short-form). Using Likert scales generated from the questionnaire and 1-tailed paired t test analysis, we found that there was significantly improved sexual function after correction of a buried penis. Variables individually showed that there was significant improvement with sexual pleasure, urinating, and with genital hygiene postoperatively. There were no significant differences concerning frequency of pain with orgasms. Surgical correction of buried penis significantly improves the functional, sexual, and psychological aspects of patient's lives.

Surgical repair of pectus excavatum and carinatum.

The author discusses different forms of pectus deformities and presents appropriate surgical methods he developed for their correction. For pectus excavatum, the surgical technique includes conservative sub-perichondral resection of deformed costal cartilages and detachment of the xiphoid process. A transverse sternotomy is performed at the upper level of the deformed sternum, which is then bent forward. The corrected sternal position is secured by a "hammock" of synthetic mesh, spread behind the sternum, and attached to the respective cartilage remnants. The pectoralis muscles are then united presternally. The initial steps of pectus carinatum correction are similar to that of pectus excavatum. The sternum, however, is not freed of its environment. A length of 3-4 cm is resected from the distal sternum and the xiphoid process is reattached in the proper anatomical direction. Measures to correct different anatomical varieties, such as pouter pigeon breast, asymmetrical pectus excavatum, and carinatum, are discussed individually.

Surgical treatment of women due to gynaecological disorders is the cause of stress and may lead to psychological changes. Studies concerning human response to stress emphasize the importance of the effect of the level of the sense of coherence, anxiety, depression, dispositional optimism and skills of expressing emotions on the quality of feelings and experiences in difficult situations. The study covered 232 women who had undergone gynaecological surgery due to various causes. Permission to conduct the research was obtained from the Bioethical Commission at the Medical University in Lublin. The study was carried out with the use of the State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory, Courtauld Emotional Control Scale (CECS), and Life Orientation Test - Revised (LOT-R). The study showed that investigations of the sense of coherence, level of anxiety and depression, and personal resources allow determination of the characteristics of patients who should be covered with special psycho-prophylactic care during the peri-operative period. In addition, the results of own studies obtained may be used for the development of adequate principles of psycho-prophylactic management in the course of the diagnostic-treatment process with respect to women who had undergone surgical treatment due to gynaecological disorders.

Supportive psychotherapy, in individual or group settings, may help improve surgical outcomes for women and girls living with female genital mutilation (FGM). To assess whether supportive psychotherapy given alongside surgical procedures to correct complications of FGM improves clinical outcomes. We searched major databases including CENTRAL, Medline, African Index Medicus, SCOPUS, PsycINFO, and others. There were no language restrictions. We checked the reference lists of retrieved studies for additional reports of relevant studies. We included studies of girls and women living with any type of FGM who received supportive psychotherapy or client education sessions alongside any surgical procedure to correct health complications from FGM. Two team members independently screened studies for eligibility. There were no eligible studies identified. There is no direct evidence for the benefits or harms of supportive psychotherapy alongside surgical procedures for women and girls living with FGM. Research evidence is urgently needed to guide clinical practice. 42015024639. © 2017 International Federation of Gynecology and Obstetrics.

Kozar, Rosemary A; McNutt, Michelle K

2010-12-01

To review the nonoperative and operative management of blunt hepatic injury in the adult trauma population. Although liver injury scale does not predict need for surgical intervention, a high-grade complex liver injury should alert the physician to a patient at increased risk of hepatic complications following nonoperative management. Blunt hepatic injury remains a frequent intraabdominal injury in the adult trauma population. The management of blunt hepatic injury has undergone a major paradigm shift from mandatory operative exploration to nonoperative management. Hemodynamic instability with a positive focused abdominal sonography for trauma and peritonitis are indications for emergent operative intervention. Although surgical intervention for blunt hepatic trauma is not as common as in years past, it is imperative that the current trauma surgeon be familiar with the surgical skill set to manage complex hepatic injuries. This study represents a review of both nonoperative and operative management of blunt hepatic injury.

Mid-line sternotomy is the routine approach for surgical repair of congenital heart diseases. However, its noticeable scar is a constant reminder of having undergone heart surgery. Several alternative approaches have been developed for simple cardiac conditions to hide the scar. Our series, consisting of 26 patients with axillary closure of atrial septal defect, is presented. The median age was 5.45 years (range 3-13), and median weight was 19.84 Kg. (range 13-37). The defect was closed directly in 13 cases, and with an autologous pericardial patch in the other 13. The number of surgical steps and time taken were the same as in median sternotomy. Functional recovery, intensive care unit stay, and hospital discharge were also standard. The cosmetic result, assessed both by patients and relatives, was excellent. Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

Effect of early correction of nasal septal deformity in unilateral cleft lip and palate on inferior turbinate hypertrophy and nasal patency.

PubMed

2018-05-01

A relatively neglected aspect of cleft lip nasal deformity is the effect of septal deviation and inferior turbinate hypertrophy (ITH) on the functional airway. In particular, ITH in the noncleft side can be especially problematic, because it reduces the healthy nasal area, creating bilateral nasal obstruction that might affect the growth of the maxillofacial skeleton. Although these anatomic and functional changes are documented, few recommendations have been developed regarding the proper approach to ITH. The aim of the present study was to asses the ITH severity and determine the degree of nasal airway patency in patients who have undergone primary correction of the nasal septum during lip repair compared to patients operated on without primary septal correction. The study population included two groups. One group consisted of twenty unilateral cleft lip palate UCLP patients who have previously undergone primary rhinoseptoplasty as part of their treatment plan. The control group consisted of twenty UCLP patients operated on without rhinoseptal correction. The Nasal Obstructive Symptom Evaluation (NOSE) scale and nasal endoscopy were used to assess nasal obstruction. The overall untreated group reported severe symptoms across all NOSE scale dimensions more frequently than children who have undergone primary rhinoseptoplasty. The difference was statistically significant for each dimensions (p < 0.05). The mean NOSE score for group A and group B was 21.4 ± 9.4 and 70.8 ± 17.2 respectively (p < 0.0001). In group A turbinate size decreased significantly (p < 0.05) compared to pre-operative data. Comparing the two groups a statistically significant difference in turbinate size was observed (p < 0.0001). The results of the present study confirm that there is a significant degree of ITH and nasal airway dysfunction in patients with UCLP. Early septal repositioning during primary cleft lip repair results in a statistically significant reduction in IT size and improvement of nasal patency. Copyright © 2018 Elsevier B.V.

2012-10-01

To call attention to the wide variety of definitions for recurrence that have been employed in studies of different invasive procedures for the treatment of Dupuytren contracture and how this important limitation has contributed to the wide range of reported results. This study reviewed definitions and rates of contracture correction and recurrence in patients undergoing invasive treatment of Dupuytren contracture. A literature search was carried out in January 2011 using the terms "Dupuytren" AND ("fasciectomy" OR "fasciotomy" OR "dermofasciectomy" OR "aponeurotomy" OR "aponeurectomy") and limited to studies in English. The search returned 218 studies, of which 21 had definitions, quantitative results for contracture correction and recurrence, and a sample size of at least 20 patients. Definitions for correction of contracture and recurrence varied greatly among articles and were almost always qualitative. Percentages of patients who achieved correction of contracture (ie, responder rate) when evaluated at various times after completion of surgery ranged from 15% to 96% for fasciectomy/aponeurectomy. Responder rates were not reported for fasciotomy/aponeurotomy. Recurrence rates ranged from 12% to 73% for patients treated with fasciectomy/aponeurectomy and from 33% to 100% for fasciotomy/aponeurotomy. Review of these reports underscored the difficulty involved in comparing correction of contracture and recurrence rates for different surgical interventions because of differences in definition and duration of follow-up. Clearly defined objective definitions for correction of contracture and for recurrence are needed for more meaningful comparisons of results achieved with different surgical interventions. Recurrence after surgical intervention for Dupuytren contracture is common. This study, which evaluated reported rates of recurrence following surgical treatment of Dupuytren contracture, provides clinicians with practical information regarding expected long-term outcomes of surgical treatment choices.

Fernández-García, P; Marco-Doménech, S F; Lizán-Tudela, L; Ibáñez-Gual, M V; Navarro-Ballester, A; Casanovas-Feliu, E

To determine the cost effectiveness of breast biopsy by 9G vacuum-assisted guided by vertical stereotaxy or ultrasonography in comparison with breast biopsy by 14G core-needle biopsy and surgical biopsy. We analyzed a total of 997 biopsies (181 vacuum-assisted, 626 core, and 190 surgical biopsies). We calculated the total costs (indirect and direct) of the three types of biopsy. We did not calculate intangible costs. We measured the percentage of correct diagnoses obtained with each technique. To identify the most cost-effective option, we calculated the mean ratios for the three types of biopsies. Total costs were €225.09 for core biopsy, €638.90 for vacuum-assisted biopsy, and €1780.01 for surgical biopsy. The overall percentage of correct diagnoses was 91.81% for core biopsy, 94.03% for vacuum-assisted biopsy, and 100% for surgical biopsy; however, these differences did not reach statistical significance (p=0.3485). For microcalcifications, the percentage of correct diagnoses was 50% for core biopsy and 96.77% for vacuum-assisted biopsy (p<0.0001). For nodules, there were no significant differences among techniques. The mean cost-effectiveness ratio considering all lesions was 2.45 for core biopsy, 6.79 for vacuum-assisted biopsy, and 17.80 for surgical biopsy. Core biopsy was the dominant option for the diagnosis of suspicious breast lesions in general. However, in cases with microcalcifications, the low percentage of correct diagnoses achieved by core biopsy (50%) advises against its use in this context, where vacuum-assisted biopsy would be the technique of choice because it is more cost-effective than surgical biopsy, the other technique indicated for biopsying microcalcifications.

This study was undertaken to compare the clinical results of traditional surgery and a percutaneous procedure for secundum type atrial septal defect (ASD) combined with pulmonary valve stenosis (PS). A total of 78 consecutive patients were identified between March 2004 and July 2012 in our institution. Thirty-five patients (44.9%) underwent percutaneous correction and the remaining 43 patients (55.1%) were treated surgically. All patients had simultaneous complete correction in both groups and no serious complications occurred. The surgical group was significantly younger (13.9 ± 13.0 versus 31.0 ± 17.5 years, P < 0.001) and had a longer mean hospital stay (12.6 ± 4.7 versus 5.3 ± 1.5 days, P < 0.001). There were no significant differences in defect size (18.0 ± 7.9 versus 16.9 ± 8.4 mm, P = 0.553) and transvalvular gradient detected by transthoracic echocardiography (TTE) (74.7 ± 28.3 versus 87.6 ± 37.8 mmHg, P = 0.089) between the two groups. Significant tricuspid regurgitation (TR) decreased from 66% to 14% in the transcatheter group and from 40% to 9% in the surgical group. Mild pulmonary regurgitation was detected in 8 patients in the transcatheter cohort and in 6 patients in the surgical cohort after the procedure. At last follow-up, 83% and 93% of the patients in the transcatheter and surgical groups, respectively, were free of any symptoms, and a significant improvement from preprocedure was observed in the transcatheter group but not in the surgical group (P = 0.005 and P = 0.062). In conclusion, transcatheter correction is a valuable alternative to surgery and allows more patients to be effectively treated in China.

This report describes the clinical findings and diagnostic images of a traumatic intrathoracic tracheal avulsion with a tracheal diverticulum in a cat. Furthermore, a complete description of the tracheal resection and anastomosis using one-lung ventilation (OLV) with total and partial intravenous anesthesia is made. A 3-year-old neutered male domestic shorthair cat weighing 6.8 kg was presented to the University Teaching Hospital for evaluation of increased respiratory noise 3 months following unknown trauma. Approximately 12 weeks prior to presentation, the cat had been seen by the primary care veterinarian for respiratory distress. At that time, the cat had undergone a tracheal ballooning procedure for a distal tracheal stricture diagnosed by tracheoscopy. The tracheal ballooning had provided only temporary relief. At presentation to our institution, the cat had increased respiratory effort with harsh upper airway noise auscultated during thoracic examination. The remainder of the physical examination was normal. Diagnostics included a tracheoscopy and a thoracic computed tomographic examination. The cat was diagnosed with tracheal avulsion, pseudotrachea with a tracheal diverticulum, and stenosis of the avulsed tracheal ends. Surgical correction of the tracheal stricture via a thoracotomy was performed using OLV with total and partial intravenous anesthesia. The cat recovered uneventfully and at last follow-up was active and doing well. This case report describes OLV using standard anesthesia equipment that is available at most private practices. Furthermore, this case describes the computed tomographic images of the intrathoracic tracheal avulsion and offers a positive outcome for tracheal resection and anastomosis. © Veterinary Emergency and Critical Care Society 2015.

People with tetraplegia face substantial physical and financial hardships. Although upper extremity reconstruction has been advocated for people with tetraplegia, these procedures are markedly underused in the United States. Population-based preference evaluation of upper extremity reconstruction is important to quantify the value of these reconstructive procedures. This study sought to establish the preferences for 3 health states: tetraplegia, tetraplegia with corrected pinch function, and tetraplegia with corrected elbow extension function. A computer-based, time trade-off survey was administered to a cohort of 81 able-bodied second-year medical students who served as a surrogate for the general public. This survey instrument has undergone pilot testing and has established face validity to evaluate the 3 health states of interest. Utilities were calculated based on an estimated 20 years of remaining life. The mean utility for the tetraplegic health state was low. On average, respondents gave up 10.8 +/- 5.0 out of a hypothetical 20 years for perfect health, for a utility of tetraplegia equal to 0.46. For recovery of pinch function, respondents gave up an average of 6.5 +/- 4.3 years, with a corresponding health utility of 0.68. For recovery of elbow extension function, respondents gave up an average of 7.6 +/- 4.5 years, with a corresponding health utility of 0.74. This study established the preferences for 2 upper extremity surgical interventions: tetraplegia with pinch and tetraplegia with elbow extension. The findings from this study place a high value on upper-limb reconstructive procedures with tetraplegia.

The cervicothoracic junction (CTJ) is the transitional region between the cervical and thoracic sections of the spinal axis. Because it is a transitional zone between the mobile lordotic cervical and rigid kyphotic thoracic spines, the CTJ is a region of potential instability. This potential for instability may be exaggerated by surgical intervention. A retrospective review of all patients who underwent surgery involving the CTJ in the Department of Neurosurgery at the Cleveland Clinic Foundation during a 5-year period was performed. The CTJ was strictly defined as encompassing the C-7 vertebra and C7-T1 disc interspace. Patients were examined after surgery to determine if treatment had failed. Failure was defined as construct failure, deformity (progression or de novo), or instability. Variables possibly associated with treatment failure were analyzed. Statistical comparisons were performed using the Fisher exact test. Between January 1998 and November 2003, 593 CTJ operations were performed. Treatment failed in 14 patients. Of all variables studied, failure was statistically associated with laminectomy and multilevel ventral corpectomies with fusion across the CTJ. Other factors statistically associated with treatment failure included histories of cervical surgery, tobacco use, and surgery for the correction of deformity. The CTJ is a vulnerable region, and this vulnerability is exacerbated by surgery. Results of the present study indicate that laminectomy across the CTJ should be supplemented with instrumentation (and fusion). Multilevel ventral corpectomies across the CTJ should also be supplemented with dorsal instrumentation. Supplemental instrumentation should be considered for patients who have undergone prior cervical surgery, have a history of tobacco use, or are undergoing surgery for deformity correction.

Urethrocutaneous fistula (UCF) is the most prevalent complication after hypospadias repair surgery. Many methods have been developed for UCF correction, and the best technique for UCF repair is determined based on the size, location, and number of fistulas, as well as the status of the surrounding skin. In this study, we introduced and evaluated a simple method for UCF correction after tubularized incised plate (TIP) repair. This clinical study was conducted on children with UCFs ≤ 4 mm that developed after TIP surgery for hypospadias repair. The skin was incised around the fistula and the tract was released from the surrounding tissues and the dartos fascia, then ligated with 5 - 0 polydioxanone (PDS) sutures. The dartos fascia, as the second layer, was covered on the fistula tract with PDS thread (gauge 5 - 0) by the continuous suture method. The skin was closed with 6 - 0 Vicryl sutures. After six months of follow-up, surgical outcomes were evaluated based on fistula relapse and other complications. After six months, relapse occurred in only one patient, a six-year-old boy with a single 4-mm distal opening, who had undergone no previous fistula repairs. Therefore, in 97.5% of the cases, relapse was non-existent. Other complications, such as urethral stenosis, intraurethral obstruction, and epidermal inclusion cysts, were not seen in the other patients during the six-month follow-up period. This repair method, which is simple, rapid, and easily learned, is highly applicable, with a high success rate for the closure of UCFs measuring up to 4 mm in any location.

Ligation under vision (LUV) is a simple method for the surgical treatment of haemorrhoids. In this study, we evaluated the results of our initial experience with the procedure in terms of postoperative pain, patients' final satisfaction and complications. We reviewed a group of patients who had undergone suture ligation of symptomatic haemorrhoids of grade II and III. This was performed with the haemorrhoids under direct vision and without the use of any ancillary instrumentation such as a Doppler sensor. All interventions were performed in the day-care surgical unit using general or regional anaesthesia. Surgical outcome and degree of postoperative pain were determined from outpatient clinic follow-up and individual phone interviews. A total of 32 patients (19 men and 13 women) with a mean age of 59 years had undergone LUV. There were 23 patients (72%) with grade II and 9 patients (28%) with grade III haemorrhoids. The indication for the surgery was bleeding in 19 patients (59%), prolapse in 6 (19%) and both in 7 (22%). A previous rubber band ligation had been carried out in 17 patients (53%). On average, the surgery took 22 min. All patients were discharged on the same day. Four %patients (12%) suffered only mild postoperative pain, 14 (44%) suffered from moderate pain and another 14 (44%) had severe pain. At follow-up (median 21 months, range 9-33 months), 28 %patients (87.5%) were completely asymptomatic at the time of the phone interview. The final result was assessed as excellent by 19 patients (60%), successful by 10 (31%), and unsuccessful by 3 (9%). All patients had complete functional recovery and there were no major surgical complications. Our data show that LUV of symptomatic haemorrhoids is a simple and safe procedure. It can be performed as effective isolated surgery for symptomatic haemorrhoids and as an additional procedure in the treatment of complex perianal pathology.

In this study, we aimed to evaluate, the efficacy of surgical methods and the factors affecting the residual stone rate by scrutinizing retrospectively the patients who had undergone renal stone surgery. Records of 109 cases of kidney stones who had been surgically treated between January 2010, and July 2013 were reviewed. Patients were divided into three groups in terms of surgical treatment; open stone surgery, percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS). Patients' history, physical examination, biochemical and radiological images and operative and postoperative data were recorded. The patients had undergone PNL (n=74; 67.9%), RIRS (n=22;20.2%), and open renal surgery (n=13; 11.9%). The mean and median ages of the patients were 46±9, 41 (21-75) and, 42 (23-67) years, respectively. The mean stone burden was 2.6±0.7 cm(2) in the PNL, 1.4±0.1 cm(2) in the RIRS, and 3.1±0.9 cm(2) in the open surgery groups. The mean operative times were 126±24 min in the PNL group, 72±12 min in the RIRS group and 82±22 min in the open surgery group. The duration of hospitalisation was 3.1±0.2 days, 1.2±0.3 days and 3.4±1.1 days respectively. While the RIRS group did not need blood transfusion, in the PNL group blood transfusions were given in the PNL (n=18), and open surgery (n=2) groups. Residual stones were detected in the PNL (n=22), open surgery (n=2), and RIRS (n=5) groups. PNL and RIRS have been seen as safe and effective methods in our self application too. However, it should not be forgotten that as a basical method, open surgery may be needed in cases of necessity.

The published return-to-play (RTP) rates for Major League Baseball (MLB) pitchers who have undergone surgical repair of superior labrum anterior-posterior (SLAP) tears vary widely and are generally accepted to be lower in the subset of competitive throwers. The efficacy of surgical treatment for MLB players is largely unknown. To examine the RTP rate and performance of MLB pitchers who have undergone SLAP tear repair between 2003 and 2010. Descriptive epidemiological study. A retrospective review of MLB pitchers undergoing SLAP repair was performed using the MLB disabled list. Data collected included the following player statistics: earned run average (ERA), walks plus hits per inning pitched (WHIP), and innings pitched (IP). The mean values for performance variables both before and after surgery were compared. A definition of return to prior performance (RTPP) was established as an ERA within 2.00 and WHIP within 0.500 of preoperative values. Twenty-four MLB players met inclusion criteria, of which 62.5% were able to RTP at the MLB level after SLAP repair surgery. Of those able to RTP, 86.7% were able to RTPP. However, the overall rate of RTPP, including those unable to RTP, was 54.2%. Mean performance analysis of the RTP group revealed a statistically significant decrease in IP for MLB pitchers throwing a mean 101.8 innings before injury and 65.53 innings after injury ( P = .004). Of those pitchers able to RTP, chances of a full recovery were good (86.7%). Our results indicate the need for future research aimed at proper surgical selection of who will return to play, as they will likely achieve full recovery. We believe this information can help surgeons advise high-level overhead-throwing athletes about expected outcomes for surgical treatment of SLAP tears.

Cerebral palsy (CP) is a group of nonprogressive syndromes of posture and motor impairment associated with lesions of the immature brain. Spastic quadriplegia is the most severe form with a high incidence of scoliosis, back pain, respiratory compromise, pelvic obliquity, and poor sitting balance. Surgical stabilization of the spine is an effective technique for correcting deformity and restoring sitting posture. The decision to operate in this group of patients is challenging. The aim of this study is to determine the benefits of surgical correction of scoliosis in children with spastic quadriplegia, the adverse effects of this treatment, and what preoperative factors affect patient outcome after surgical correction. A systematic review was undertaken to identify studies describing benefits and adverse effects of surgery in spastic quadriplegia. Factors affecting patient outcome following surgical correction of scoliosis were assessed. Studies involving adults and nonspastic quadriplegia were excluded. A total of 10 case series and 1 prospective and 3 retrospective cohort studies met inclusion criteria. There was significant variation in the overall risk of complications (range, 10.9-70.9%), mortality (range, 2.8-19%), respiratory/pulmonary complications (range, 26.9-57.1%), and infection (range, 2.5-56.8%). Factors associated with a worse outcome were a significant degree of thoracic kyphosis, days in the intensive care unit, and poor nutritional status. Caregivers report a high degree of satisfaction with scoliosis surgery for children with spastic quadriplegia. There is limited evidence of preoperative factors that can predict patient outcome after scoliosis. There is a need for well-designed prospective studies of scoliosis surgery in spastic quadriplegia.

Correcting prominent ears with the island technique.

PubMed

DeMoura, L F

1977-01-01

A surgical procedure is described which corrects the ansiform ear by repositioning and reconstructing the anthelix and the anterior crus with the formation of the triangular fossa. This corrects the scaphoconchal angle and improves the cephaloauricular angle, overcoming the problem of prominent ears. Correction in early childhood is recommended in order to avoid personality problems that may result from the deformity, particularly in boys. The technique employed yields important advantages: (1) prolonged use of the helmet-type of surgical dressing is unnecessary; (2) scars are less conspicuous; (3) the outcome is attractive and normal; (4) bleeding and inflammatory complications are avoided; and (5) recurrence of the malformation is unlikely.

Spontaneous pneumothorax during pregnancy has potentially serious implications for the mother and fetus. When surgical correction is required, complex maternal physiologic alterations may significantly affect fetal well-being. A woman underwent thoracoscopic lung resection and pleurodesis at 29 weeks of gestation. At various points during the procedure, maternal hemodynamic and respiratory consequences of anesthetic and surgical management resulted in severe fetal heart rate (FHR) decelerations and bradycardia. In each instance, physiologic manipulations based on an understanding of the likely cause of fetal hypoxia allowed correction of the FHR abnormalities without delivery. Nonsurgical perinatal intervention based on FHR monitoring and analysis of the likely pathophysiologic abnormalities underlying fetal decelerations may allow the gravid woman to undergo complex procedures and continue the pregnancy.

Creating an aesthetically appealing result using thoracoplasty, especially when correcting extensive deformities, but only causing low morbidity, is challenging. The frequency of thoracoplasties in cases of pectus carinatum (PC) has increased due to improved experience and modified surgical techniques, resulting in low morbidity and low complication rates. The indications for surgical treatment are still controversial and, in most cases, remain aesthetic or psychological rather than physiological. However, whether cardiopulmonary function changes after surgical repair remains a matter of controversy. We sought to investigate and shed light on published knowledge regarding this question. We searched MEDLINE and PubMed databases, using various defined search phrases and inclusion criteria, to identify articles on pre- and postoperative cardiopulmonary evaluation and outcomes. Six studies met the inclusion criteria: 5 studies evaluated patients with PC for cardiopulmonary outcomes after chest wall surgery and 1 did so following conservative compression treatment. In these studies, surgical and conservative correction of PC did not reduce absolute lung volumes and spirometric measurements and consequently had no pathogenic effect on cardiopulmonary function. The results of this systematic review suggest that surgical correction of PC has no symptomatic pathogenic effect on cardiopulmonary function. The results, however, revealed both heterogeneity in the examinations used and inconsistent methods within each study. Further prospective trials with a stronger methodological design are necessary to objectively confirm that surgical correction of PC does not impair cardiopulmonary function. © The Author 2017.

The presence of two or more epileptogenic pathologies in patients with epilepsy is often observed, and the coexistence of focal cortical dysplasia (FCD) with hippocampal sclerosis (HS) is one of the most frequent clinical presentations. Although surgical resection has been an important treatment for patients with refractory epilepsy associated with FCD, there are few studies on the surgical treatment of FCD accompanied by HS, and treatment by resection of both neocortical dysplastic tissue and hippocampus is still controversial. We retrospectively recruited epilepsy patients who had undergone surgical treatment for refractory epilepsy with the pathologic diagnosis of FCD and the radiologic evidence of HS. We evaluated the prognostic roles of clinical factors, various diagnostic modalities, surgical procedures, and the severity of pathology. A total of 40 patients were included, and only 35.0% of patients became seizure free. Complete resection of the epileptogenic area (p = 0.02), and the presence of dysmorphic neurons or balloon cells on histopathology (p = 0.01) were associated with favorable surgical outcomes. Patients who underwent hippocampal resection were more likely to have a favorable surgical outcome (p = 0.02). We show that patients with complete resection of epileptogenic area, the presence of dysmorphic neurons or balloon cells on histopathology, or resection of hippocampus have a higher chance of a favorable surgical outcome. We believe that this observation is useful in planning of surgical procedures and predicting the prognoses of individual patients with FCD patients accompanied by HS.

2017-09-01

This descriptive study aimed to evaluate the information needs of breast cancer patients who have undergone surgery, and the level to which those information needs are met in the west of Turkey. It was conducted in 55 women who had undergone surgical intervention between March 2013 and March 2014 in a university hospital in the west of Turkey. A personal information form and the Patient Information Needs Scale were used to gather data. Descriptive statistics, the Chi-square test, and the Wilcoxon signed-rank test were used to analyze the data. It was found that the information need of the patients (3.9 +/- 0.6) was near the "very important" level, and that this need was "somewhat met" (2.4 +/- 0.9). When the information needs of the patients and the level to which those needs were fulfilled were compared, the level of fulfillment was statistically significantly lower (p < 0.001). Among the different subscales evaluated, information relating to medication was the most needed, and the information needs pertaining to this subscale were met to a greater degree (p < 0.05) than the remaining subscales. The results showed that the information needs, primarily the medication-related information needs, of the patients were high, but that the level of meeting these needs was low. It should be considered important for patients who have undergone breast cancer surgery to be kept informed and provided with information regarding their medication.

Surgery for epilepsy dates back to 1886 and has undergone significant developments. Today it is considered a key treatment modality in patients who are resistant to pharmacological intervention. It improves seizure control, cognition and quality of life. New technologies, advances in surgical technique and progress in scientific research underlie the expansion of surgery in epilepsy treatment. Effectiveness of surgical treatment depends on several factors including the type of epilepsy, the underlying pathology and the localisation of the epileptogenic zone. Timely referral to an experienced epilepsy surgery centre is important to allow the greatest chance of seizure control and to minimise associated morbidity and mortality. Following referral, patients undergo thorough presurgical investigation to evaluate their suitability for surgery. The commonest form of epilepsy treated by surgery is mesial temporal lobe sclerosis and there is Class I evidence for the medium-term efficacy of temporal lobe resection from two randomised control trials. Various other forms of epilepsy are now considered for resective and neuromodulatory surgical intervention due to favourable results. In this article, the authors review the current status of surgical treatment for epilepsy including the presurgical evaluation of patients, surgical techniques and the future directions in epilepsy surgery.

Several pancreatic diseases may require surgical treatment, with most of these procedures classified as resection or drainage. Resection procedures, which are usually performed to remove pancreatic tumors, include pancreatoduodenectomy, central pancreatectomy, distal pancreatectomy, and total pancreatectomy. Drainage procedures are usually performed to treat chronic pancreatitis after the failure of medical therapy and include the Puestow and Frey procedures. The type of surgery depends not only on the patient's symptoms and the location of the disease, but also on the expertise of the surgeon. Radiologists should become familiar with these surgical procedures to better understand postoperative changes in anatomic findings. Multidetector computed tomography is the modality of choice for identifying normal findings after surgery, postoperative complications, and tumor recurrence in patients who have undergone pancreatic surgery.

2008-01-01

Endoscopic skull base surgery has undergone rapid advancement in the past decade moving from pituitary surgery to suprasellar lesions and now to a myriad of lesions extending from the cribriform plate to C2 and laterally out to the infratemporal fossa and petrous apex. Evolution of several technological advances as well as advances in understanding of endoscopic anatomy and the development of surgical techniques both in resection and reconstruction have fostered this capability. Management of benign disease via endoscopic methods is largely accepted now but more data is needed before the controversy on the role of endoscopic management of malignant disease is decided. Continued advances in surgical technique, navigation systems, endoscopic imaging technology, and robotics assure continued brisk evolution in this expanding field. PMID:19434274

To elaborate a clinical and X-ray classification of osteonecrosis of the low jaw in people with desomorphine or pervitin addiction. Ninety-two patients with drug addiction who had undergone orthopantomography, direct frontal X-ray of the skull, and multislice computed tomography, followed by multiplanar and three-dimensional imaging reconstruction were examined. One hundred thirty four X-ray films and 74 computed tomographic images were analyzed. The authors proposed a clinical and X-ray classification of osteonecrosis of the low jaw in people with desomorphine or pervitin addiction and elaborated recommendations for surgical interventions on the basis of the developed classification. The developed clinical and X-ray classification and recommendations for surgical interventions may be used to treat osteonecroses of various etiology.

Neck dissection is an important treatment for metastases from upper aerodigestive carcinoma; an event that markedly reduces survival. Since its inception, the philosophy of the procedure has undergone significant change from one of radicalism to the current conservative approach. Furthermore, nonsurgical modalities have been introduced, and, in many situations, have supplanted neck surgery. The refinements of imaging the neck based on the concept of neck level involvement has encouraged new philosophies to evolve that seem to benefit patient outcomes particularly as this relates to diminished morbidity. The purpose of this review was to highlight the new paradigms for surgical removal of neck metastases using an evidence-based approach. © 2014 Wiley Periodicals, Inc.

Dilation of the ascending aorta and aortic dissections are often seen in Marfan syndrome; however, true aneurysms of the subclavian and axillary arteries rarely seem to develop in patients who have this disease. We present the case of a 58-year-old man with Marfan syndrome who had undergone a Bentall procedure and thoracoabdominal aortic repair for an aortic dissection and who later developed multiple aneurysmal dilations of his right subclavian and axillary arteries. The aneurysms were successfully repaired by means of a surgical bypass technique in which a Dacron graft was placed between the carotid and brachial arteries. We also discuss our strategy for determining the optimal surgical approach in these patients.

Minimally invasive surgery in the human was first identified in mid 900's. The procedure as is more commonly practiced now was first reported in 1912. There have been many advances and new techniques developed in the past 100 years. Equine laparoscopy, was first reported in the 1970's, and similarly has undergone much transformation in the last 40 years. It is now considered the standard of care in many surgical techniques such as cryptorchidectomy, ovariectomy, nephrosplenic space ablation, standing abdominal exploratory, and many other reproductive surgeries. This manuscript describes the history of minimally invasive surgery, and highlights many of the techniques that are currently performed in equine surgery. Special attention is given to instrumentation, ligating techniques, and the surgical principles of equine minimally invasive surgery. PMID:23762585

The management of benign papilloma (BP) without atypia identified on breast core needle biopsy (CNB) is controversial. We describe the clinicopathologic features of 80 patients with such lesions in our institution, with an upgrade rate to malignancy of 3.8%. A multidisciplinary approach to select patients for surgical excision is recommended. Background The management of benign papilloma (BP) without atypia identified on breast core needle biopsy (CNB) is controversial. In this study, we determined the upgrade rate to malignancy for BPs without atypia diagnosed on CNB and whether there are factors associated with upgrade. Methods Through our pathology database search, we studied 80 BPs without atypia identified on CNB from 80 patients from 1997 to 2010, including 30 lesions that had undergone excision and 50 lesions that had undergone ≥ 2 years of radiologic follow-up. Associations between surgery or upgrade to malignancy and clinical, radiologic, and pathologic features were analyzed. Results Mass lesions, lesions sampled by ultrasound-guided CNB, and palpable lesions were associated with surgical excision. All 3 upgraded cases were mass lesions sampled by ultrasound-guided CNB. None of the lesions with radiologic follow-up only were upgraded to malignancy. The overall upgrade rate was 3.8%. None of the clinical, radiologic, or histologic features were predictive of upgrade. Conclusion Because the majority of patients can be safely managed with radiologic surveillance, a selective approach for surgical excision is recommended. Our proposed criteria for excision include pathologic/radiologic discordance or sampling by ultrasound-guided CNB without vacuum assistance when the patient is symptomatic or lesion size is ≥ 1.5 cm.

To develop a specific rehabilitation protocol for patients who have undergone surgical repair of acute aneurysmal subarachnoid hemorrhage (aSAH), and to determine the time at which verticalization should be initiated after aSAH. Sixty-five patients who underwent acute-term surgery for aSAH and early rehabilitation were evaluated in groups: Group 1 (n=34) started verticalization on days 2-5 post-bleeding whereas Group 2 (n=31) started verticalization approximately day 12 post-bleeding. All patients were monitored for early complications, vasospasm and ischemia. Assessments of motor status, depression and anxiety (using Zung scales), and cognitive status (using the Mini-Mental State Examination (MMSE)) were conducted at discharge and at 1 and 3 months post-surgery. At discharge, Group 1 had a significantly higher proportion of patients with ischemia than Group 2 (p=0.004). Group 1 had a higher proportion of patients with hemiparesis than Group 2 three months post-surgery (p=0.015). Group 1 patients scored significantly higher on the Zung depression scale than Group 2 patients at 1 month (p=0.005) and 3 months post-surgery (p=0.001; the same applies to the Zung anxiety scale (p=0.006 and p=0.000, respectively). Group 2 patients scored significantly higher on the MMSE than those in Group 1 at discharge (p=0.040) and 1 month post-surgery (p=0.025). Early verticalization had no effect with respect to preventing early postoperative complications in this patient group. Once a patient has undergone acute surgical repair of aSAH, it is safe and preferred that rehabilitation be initiated immediately postsurgery. However, verticalization should not start prior to day 12 post-bleeding.

Colorectal cancer is the second most common cause of death in the USA. The need for screening colonoscopies, and thus adequately trained endoscopists, particularly in rural areas, is on the rise. Recent increases in required endoscopic cases for surgical resident graduation by the Surgery Residency Review Committee (RRC) further emphasize the need for more effective endoscopic training during residency to determine if a virtual reality colonoscopy simulator enhances surgical resident endoscopic education by detecting improvement in colonoscopy skills before and after 6 weeks of formal clinical endoscopic training. We conducted a retrospective review of prospectively collected surgery resident data on an endoscopy simulator. Residents performed four different clinical scenarios on the endoscopic simulator before and after a 6-week endoscopic training course. Data were collected over a 5-year period from 94 different residents performing a total of 795 colonoscopic simulation scenarios. Main outcome measures included time to cecal intubation, "red out" time, and severity of simulated patient discomfort (mild, moderate, severe, extreme) during colonoscopy scenarios. Average time to intubation of the cecum was 6.8 min for those residents who had not undergone endoscopic training versus 4.4 min for those who had undergone endoscopic training (p < 0.001). Residents who could be compared against themselves (pre vs. post-training), cecal intubation times decreased from 7.1 to 4.3 min (p < 0.001). Post-endoscopy rotation residents caused less severe discomfort during simulated colonoscopy than pre-endoscopy rotation residents (4 vs. 10%; p = 0.004). Virtual reality endoscopic simulation is an effective tool for both augmenting surgical resident endoscopy cancer education and measuring improvement in resident performance after formal clinical endoscopic training.

OBJECTIVE To assess hospital surgical-site infection (SSI) identification and reporting following colon surgery and abdominal hysterectomy via a statewide external validation METHODS Infection preventionists (IPs) from the California Department of Public Health (CDPH) performed on-site SSI validation for surgical procedures performed in hospitals that voluntarily participated. Validation involved chart review of SSI cases previously reported by hospitals plus review of patient records flagged for review by claims codes suggestive of SSI. We assessed the sensitivity of traditional surveillance and the added benefit of claims-based surveillance. We also evaluated the positive predictive value of claims-based surveillance (ie, workload efficiency). RESULTS Upon validation review, CDPH IPs identified 239 SSIs following colon surgery at 42 hospitals and 76 SSIs following abdominal hysterectomy at 34 hospitals. For colon surgery, traditional surveillance had a sensitivity of 50% (47% for deep incisional or organ/space [DI/OS] SSI), compared to 84% (88% for DI/OS SSI) for claims-based surveillance. For abdominal hysterectomy, traditional surveillance had a sensitivity of 68% (67% for DI/OS SSI) compared to 74% (78% for DI/OS SSI) for claims-based surveillance. Claims-based surveillance was also efficient, with 1 SSI identified for every 2 patients flagged for review who had undergone abdominal hysterectomy and for every 2.6 patients flagged for review who had undergone colon surgery. Overall, CDPH identified previously unreported SSIs in 74% of validation hospitals performing colon surgery and 35% of validation hospitals performing abdominal hysterectomy. CONCLUSIONS Claims-based surveillance is a standardized approach that hospitals can use to augment traditional surveillance methods and health departments can use for external validation.

This study evaluates hippocampal pathology through usage of ultra-high field 9.4T ex-vivo imaging of resected surgical specimens in patients who have undergone temporal lobe epilepsy surgery. This is a retrospective interpretation of prospectively acquired data. MRI scanning of resected surgical specimens from patients who have undergone temporal lobe epilepsy surgery was performed on a 9.4T small bore Varian MR magnet. Structural images employed a balanced steady-state free precession sequence (TrueFISP). Six patients (3 females; 3 males) were included in this study with an average age at surgery of 40.7 years (range 20Y_"60) (one was used as a control reference). Two neuroradiologists qualitatively reviewed the ex-vivo MRIs of resected specimens while blinded to the histopathology reports for the ability to identify abnormal features in hippocampal subfield structures. The hippocampal subfields were reliably identified on the 9.4T ex-vivo scans in the hippocampal head region and hippocampal body region by both neuroradiologists in all 6 patients. There was high concordance to pathology for abnormalities detected in the CA1, CA2, CA3 and CA4 subfields. Detection of abnormalities in the dentate gyrus was also high with detection in 4 of 5 cases. The Cohen's kappa between the two neuroradiologists was calculated at 0.734 SE=0.102. Ex-vivo 9.4T specimen imaging can detect abnormalities in CA1, CA2, CA3, CA4 and DG in both the hippocampal head and body. There was good concordance between qualitative findings and histopathological abnormalities for CA1, CA2, CA3, CA4 and DG. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Background. Being predictive of the entire nodal bed, sentinel lymph node biopsy (SLNB) is invaluable in the surgical management of melanoma. Although the concept is simple, sentinel lymph node (SLN) identification and removal can be technically challenging. Methods. A total of 102 consecutive patients have undergone SLNB in the Division of Plastic and Reconstructive Surgery of Soroka University Medical Center from 2009 to 2012. Patients have undergone SLNB using a radioactive tracer and blue stain in order to identify the SLN. Although SLNB usually precedes the wide excision of melanoma, primary lesions in close proximity (<10 cm) to the lymph basin require wide excision before beginning the SLN quest. Results. All pathology reports confirmed the excision of lymph nodes. Conclusions. When treating MM in close proximity to the lymph basin, changing the sequence of the SLNB procedure seems to increase the efficacy of the method. PMID:24660067

Surgically assisted rapid maxillary expansion (SARME) is usually considered the gold standard for maxillary transverse expansion in adults. However, a second surgical procedure is needed in cases of associated sagittal or vertical discrepancies. We describe the use of two new innovative devices for the correction of discrepancies in all dimensions during a single surgical procedure, thus reducing treatment duration. We report the case of a 21-year-old female patient, referred to our department for skeletal Class III malocclusion associated with right-side laterognathism and transverse maxillary deficiency. The patient underwent one-stage surgery, using sliding osteosynthesis plates and an adjustable bone-borne distractor. Pre-surgical orthodontics consisted in leveling and aligning the mandibular arch; maxillary leveling was initiated 3 months before surgery. Postoperative palatal distraction combined with orthodontic finishing enabled complete correction of dental and bony discrepancies after 3 months. In our experience, treatment of transverse, sagittal and vertical discrepancies has been possible in a single surgical procedure, using two innovative techniques: sliding osteosynthesis and an adjustable bone distractor. Two years post-surgery, the correction is stable in all dimensions. Copyright © 2015. Published by Elsevier Masson SAS.

Prevention of Surgical Fires: A Certification Course for Healthcare Providers.

Fisher, Marquessa

2015-08-01

An estimated 550 to 650 surgical fires occur annually in the United States. Surgical fires may have severe consequences, including burns, disfigurement, long-term medical care, or death. This article introduces a potential certification program for the prevention of surgical fires. A pilot study was conducted with a convenience sample of 10 anesthesia providers who participated in the education module. The overall objective was to educate surgical team members and to prepare them to become certified in surgical fire prevention. On completion of the education module, participants completed the 50-question certification examination. The mean pretest score was 66%; none of the participants had enough correct responses (85%) to be considered competent in surgical fire prevention. The mean post- test score was 92.80%, with all participants answering at least 85% of questions correct. A paired-samples t test showed a statistically significant increase in knowledge: t (df = 9) = 11.40; P = .001. Results of the pilot study indicate that this course can remediate gaps in knowledge of surgical fire prevention for providers. Their poor performance on the pretest suggests that many providers may not receive sufficient instruction in surgical fire prevention.

The Role of Serum Beta hCG in Early Diagnosis and Management Strategy of Ectopic Pregnancy.

The presentation of Ectopic Pregnancy (EP) can be highly variable and serum Beta hCG estimation plays an important role in early diagnosis. Aim of the study was to determine the trends of hCG levels in EP and to explore the role of hCG in decisions related to management and follow-up of EPs. A retrospective study of women who had EPs from January 2006 to December 2012 at an advanced tertiary care centre in southern India was carried out. These women had undergone treatment based on the hospital protocol. The study identified 337 women with EP. Thirty one surgically confirmed cases were diagnosed below the discriminatory zone of 1500 mIU/ml. Among women who had Beta hCG estimations 48 hours apart, plateauing was observed in 22.5% while decrease >15% was noted in 26.8%. Almost half (47.9%) of the cases had an increase >15% and a few (2.8%) demonstrated an initial fall followed by a rise in titres. In 23.9% of these women, there was a rise >53% similar to intrauterine pregnancy. The average pre-treatment Beta hCG was 429.8, 3866.2 and 12961.5 mIU/ml for those who received expectant, medical and direct surgical treatment respectively. 43 women with relative contraindications received medical management and 39 were lost to follow-up after medical and expectant management. Excluding them, the success rate of these two modalities was 76.6% and 85.0% respectively. No single level of Beta hCG is diagnostic of EP and serial levels can demonstrate atypical trends in some cases. Hence, interpretation of these results should be done in conjunction with clinical and sonographic findings to arrive at a correct diagnosis.

Audit of 117 otoplasties for prominent ear by one surgeon using a cartilage-cutting procedure.

The plethora of surgical procedures for prominent ear correction reflects lack of satisfaction with outcomes achieved. This paper describes a cartilage-cutting otoplasty procedure and reports an audit of its outcomes. Discharge coding was used to retrospectively identify patients who had undergone the otoplasty of interest at Middlemore Hospital, Auckland, during the 5 years from March 2010 to the end of February 2015. Hospital records were accessed. Demographic, procedure and patient satisfaction data were recorded and analysed (PASW/SPSS Statistics 18.0). Chi-square test and t-test were used to assess associations, with significance accepted at two-sided P < 0.05. Sixty-four patients underwent the specified otoplasty (54.7% females: mean age 9.5 years (standard deviation, SD: 4.2; range: 4-20)), of whom 93.8% had bilateral procedures with mean surgical time of 61 min (SD: 14; range: 34-94). This was significantly shorter (P < 0.001) than for bilateral surgeries by all other techniques and surgeons in the review period. None of the 117 procedures of interest subsequently had suture extrusion or revision surgery. Mean time from surgery to satisfaction determination was 993 days (SD: 521; range: 111-1850) for 43 (67.2%) patients. 23.3% believed that there had been aesthetically insignificant partial recurrence of prominence, typically of one ear only. This was insufficient for all but one patient to consider repeat otoplasty. Surgery outcome was rated 'very satisfactory' and 'satisfactory' by 90.7% and 9.3% of patients/parents, respectively. All would recommend the surgery to others. With infrequent complications and recurrence requiring revision, and without long-term reliance on sutures, the otoplasty reported is time-efficient, safe and generates high patient satisfaction. © 2018 Royal Australasian College of Surgeons.

In decades of technical developments after the first surgical corrections of spinal deformities, the set of devices, techniques, and tools available to the surgeons has widened dramatically. Nevertheless, the rate of complications due to mechanical failure of the fixation or the instrumentation remains rather high. Indeed, basic and clinical research about the principles of deformity correction and the optimal surgical strategies (i.e., the choice of the fusion length, the most appropriate instrumentation, and the degree of tolerable correction) did not progress as much as the implantable devices and the surgical techniques. In this work, a software approach for the biomechanical simulation of the correction of patient-specific spinal deformities aimed to the identification of its biomechanical principles is presented. The method is based on three-dimensional reconstructions of the spinal anatomy obtained from biplanar radiographic images. A user-friendly graphical user interface allows for the planning of the desired deformity correction and to simulate the implantation of pedicle screws. Robust meshing of the instrumented spine is provided by using consolidated computational geometry and meshing libraries. Based on a finite element simulation, the program is able to predict the loads and stresses acting in the instrumentation as well as those in the biological tissues. A simple test case (reduction of a low-grade spondylolisthesis at L3–L4) was simulated as a proof of concept, and showed plausible results. Despite the numerous limitations of this approach which will be addressed in future implementations, the preliminary outcome is promising and encourages a wide effort toward its refinement.

Traditional planning method for orthognathic surgery has limitations of cephalometric analysis, especially for patients with asymmetry. The aim of this study was to assess surgical plan modification after 3-demensional (3D) simulation. The procedures were to perform traditional surgical planning, construction of 3D model for the initial surgical plan (P1), 3D model of altered surgical plan after simulation (P2), comparison between P1 and P2 models, surgical execution, and postoperative validation using superimposition and root-mean-square difference (RMSD) between postoperative 3D image and P2 simulation model. Surgical plan was modified after 3D simulation in 93% of the cases. Absolute linear changes of landmarks in mediolateral direction (x-axis) were significant and between 1.11 to 1.62 mm. The pitch, yaw, and roll rotation as well as ramus inclination correction also showed significant changes after the 3D planning. Yaw rotation of the maxillomandibular complex (1.88 ± 0.32°) and change of ramus inclination (3.37 ± 3.21°) were most frequently performed for correction of the facial asymmetry. Errors between the postsurgical image and 3D simulation were acceptable, with RMSD 0.63 ± 0.25 mm for the maxilla and 0.85 ± 0.41 mm for the mandible. The information from this study could be used to augment the clinical planning and surgical execution when a conventional approach is applied. PMID:28071714

Presbyopia is a physiologic inevitability that causes gradual loss of accommodation during the fifth decade of life. The correction of presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. Different approaches on the cornea, the crystalline lens and the sclera are being pursued to achieve surgical correction of this disability. There are however, a number of limitations and considerations that have prevented widespread acceptance of surgical correction for presbyopia. The quality of vision, optical and visual distortions, regression of effect, complications such as corneal ectasia and haze, anisometropia after monovision correction, impaired distance vision and the invasive nature of the currently techniques have limited the utilization of presbyopia surgery. The purpose of this paper is to provide an update of current procedures available for presbyopia correction and their limitations. PMID:24669140

The accurate reduction of tibial plateau malunions can be challenging without guidance. In this work, we report on a novel technique that combines 3-dimensional computer-assisted planning with patient-specific surgical guides for improving reliability and accuracy of complex intraarticular corrective osteotomies. Preoperative planning based on 3-dimensional bone models was performed to simulate fragment mobilization and reduction in 3 cases. Surgical implementation of the preoperative plan using patient-specific cutting and reduction guides was evaluated; benefits and limitations of the approach were identified and discussed. The preliminary results are encouraging and show that complex, intraarticular corrective osteotomies can be accurately performed with this technique. For selective patients with complex malunions around the tibia plateau, this method might be an attractive option, with the potential to facilitate achieving the most accurate correction possible.

Refractive error is one of leading ophthalmic diseases for both genders all over the world. Laser refractive correction surgery, e.g., laser in-situ keratomileusis (LASIK), has been commonly used worldwide. The prediction of surgical parameters, e.g., corneal ablation depth, depends on the doctor’s experience, theoretical formula and surgery reference manual in the preoperative diagnosis. The error of prediction may present a potential surgical risk and complication. Being aware of the surgery parameters is important because these can be used to estimate a patient’s post-operative visual quality and help the surgeon plan a suitable treatment. Therefore, in this paper we discuss data mining techniques that can be utilized for the prediction of laser refractive correction surgery parameters. It can provide the surgeon with a reference for possible surgical parameters and outcomes of the patient before the laser refractive correction surgery.

To evaluate the safety and efficacy of excimer laser refractive surgery in correcting refractive error in eyes that have undergone previous penetrating keratoplasty (PK). Twenty-three keratorefractive procedures on 16 eyes from 16 consecutive subjects were evaluated between 2002 and 2008. Each patient presented a previous history of a PK with subsequent postoperative myopia and astigmatism. Keratometric value, manifest refraction, best-corrected visual acuity, uncorrected visual acuity, and complications were determined. There were a total of 14 photorefractive keratectomy (PRK) procedures performed on 11 eyes and 9 laser in situ keratomileusis (LASIK) procedures performed on 5 eyes. In the PRK group, the preoperative post-PK manifest refractive spherical equivalent and cylindrical error were -6.22 +/- 6.23 diopter and 5.23 +/- 2.26 D, respectively. The PRK postoperative manifest refractive spherical equivalent and cylindrical error were -3.61 +/- 4.23 D (P=0.25) and 3.21 +/- 1.78 D (P=0.02), respectively. In the LASIK group, the preoperative post-PK manifest refractive spherical equivalent and cylindrical error were -3.05 +/- 3.29 D and 4.11 +/- 2.38 D, respectively. The LASIK postoperative manifest refractive spherical equivalent and cylindrical error were -1.51 +/- 2.02 D (P=0.24) and 2.08 +/- 1.26 D (P=0.03), respectively. There was a 2-line or greater improvement of uncorrected visual acuity in 8 of the 14 PRK treatments and 5 of the 9 LASIK treatments. There were two episodes of acute graft rejection. One of the episodes resolved with topical and oral corticosteroids, and the other episode required a repeat corneal transplantation. PRK and LASIK are effective tools in reducing surgically induced astigmatism after penetrating corneal transplantation in most patients in this case series. The reduction of astigmatism may allow improved contact lens or spectacle fitting to achieve best-corrected binocular visual acuity.

Magnetic resonance imaging is an important noninvasive modality in characterizing cartilage morphology, biochemistry, and function. It serves as a valuable objective outcome measure in diagnosing pathology at the time of initial injury, guiding surgical planning, and evaluating postsurgical repair. This article reviews the current literature addressing the recent advances in qualitative and quantitative magnetic resonance imaging techniques in the preoperative setting, and in patients who have undergone cartilage repair techniques such as microfracture, autologous cartilage transplantation, or osteochondral transplantation.

Purpose To compare postoperative astigmatic correction between femtosecond lenticule extraction (FLEx) and small-incision lenticule extraction (SMILE) in eyes with myopic astigmatism. Methods We examined 26 eyes of 26 patients undergoing FLEx and 26 eyes of 26 patients undergoing SMILE to correct myopic astigmatism (manifest astigmatism of 1 diopter (D) or more). Visual acuity, cylindrical refraction, the predictability of the astigmatic correction, and the astigmatic vector components using Alpin’s method, were compared between the two groups 3 months postoperatively. Results We found no statistically significant difference in manifest cylindrical refraction (p=0.74) or in the percentage of eyes within ± 0.50 D of their refraction (p=0.47) after the two surgical procedures. Moreover, no statistically significant difference was detected between the groups in astigmatic vector components, namely, surgically induced astigmatism (0.80), target induced astigmatism (p=0.87), astigmatic correction index (p=0.77), angle of error (p=0.24), difference vector (p=0.76), index of success (p=0.91), flattening effect (p=0.79), and flattening index (p=0.84). Conclusions Both FLEx and SMILE procedures are essentially equivalent in correcting myopic astigmatism using vector analysis, suggesting that the lifting or non-lifting of the flap does not significantly affect astigmatic outcomes after these surgical procedures.

Female genital mutilation (FGM) is a violation of human rights; yet, more than 100 million females are estimated to have undergone the procedure worldwide. There is an increased need for physician education in treating FGM. Female pelvic surgeons have a unique opportunity to treat this population of patients. Here, we depict the classification of FGM and a general approach to FGM reversal. We specifically address the procedure of type III FGM reversal, or defibulation. In this video, we first highlight the importance of the problem of FGM. Next, we present the classification of FGM using an original, simple, schematic diagram highlighting they key anatomic structures involved in the four types of FGM. We then present a simple case of reversal of type III FGM, a procedure also known as defibulation. After depicting the surgical procedure, we discuss clinical results and summarize key principles of the defibulation procedure. Our patient was a 25-year-old woman who had undergone type III FGM as a child in Somalia. She desired restoration of vaginal function. We performed a reversal, and her postoperative course was uncomplicated. By 6 weeks postoperatively, she was able to engage in sexual intercourse without dyspareunia. FGM is a problem at the doorsteps of female pelvic medicine and reconstructive surgery. Our video demonstrates a basic surgical approach that can be applied to simple cases of type III FGM presenting to the female pelvic surgeon.

To compare morphological, power Doppler, and contrast-enhanced ultrasound (CEUS) features of the Achilles tendon between asymptomatic athletes and athletes who had undergone surgical repair of a previous rupture. Twenty-four athletes were divided in two groups (A and B). Group A included 14 patients with a median age of 32 years (range 27 to 47 years) who had undergone surgical repair for unilateral Achilles tendon rupture. Group B (control group) included 10 subjects with a median age of 34 years (range 27 to 40 years) with no previous or present history of tendinopathy. All patients were evaluated with ultrasound, power Doppler, and CEUS with second-generation contrast agent. We studied the uninjured Achilles tendon in athletes of group A and either the left or the right Achilles tendon of the athletes in group B. CEUS showed a significantly greater ability to detect a greater number of vascular spots within the uninjured tendon of group A compared to group B (<0.05). In athletes who had suffered a tear of an Achilles tendon, CEUS detected small vessels that were not identified by power Doppler ultrasound in the uninjured contralateral Achilles tendon. CEUS is useful to evaluate vascularity not detected by other imaging techniques. Vascularity in the uninjured tendon seems to be increased in patients who had a previous rupture.

If a skeletal anterior open bite malocclusion is treated by orthognathic surgery directed only at the mandible, the lower jaw is repositioned upward in a counter-clockwise rotation. However, this procedure has a high risk of relapse. In the present study, the key factors associated with post-surgical stability of corrected skeletal anterior open bite malocclusions were investigated. Eighteen orthognathic patients were subjected to cephalometric analysis to assess the dental and skeletal changes following mandibular surgery for the correction of an anterior open bite. The patients were divided into two groups, determined by an increase or decrease in nasion-menton (N-Me) distance as a consequence of surgery. Changes in overbite, the displacements of molars and positional changes in Menton were evaluated immediately before and after surgery and after a minimum of one year post-operatively. The group with a decreased N-Me distance exhibited a significantly greater backward positioning of the mandible. The group with an increased N-Me distance experienced significantly greater dentoalveolar extrusion of the lower molars. A sufficient mandibular backward repositioning is an effective technique in the prevention of open bite relapse. In addition, it is important not to induce molar extrusion during post-surgical orthodontic treatment to preserve stability of the surgical open bite correction.

Surgical Options for the Refractive Correction of Keratoconus: Myth or Reality

Zaldivar, R.; Aiello, F.; Madrid-Costa, D.

2017-01-01

Keratoconus provides a decrease of quality of life to the patients who suffer from it. The treatment used as well as the method to correct the refractive error of these patients may influence on the impact of the disease on their quality of life. The purpose of this review is to describe the evidence about the conservative surgical treatment for keratoconus aiming to therapeutic and refractive effect. The visual rehabilitation for keratoconic corneas requires addressing three concerns: halting the ectatic process, improving corneal shape, and minimizing the residual refractive error. Cross-linking can halt the disease progression, intrastromal corneal ring segments can improve the corneal shape and hence the visual quality and reduce the refractive error, PRK can correct mild-moderate refractive error, and intraocular lenses can correct from low to high refractive error associated with keratoconus. Any of these surgical options can be performed alone or combined with the other techniques depending on what the case requires. Although it could be considered that the surgical option for the refracto-therapeutic treatment of the keratoconus is a reality, controlled, randomized studies with larger cohorts and longer follow-up periods are needed to determine which refractive procedure and/or sequence are most suitable for each case.

Introduction. Congenital pelviureteric junction obstruction (PUJO) is one of the most common causes of hydronephrosis. Historically, open dismembered pyeloplasty has been considered the gold standard intervention for correcting PUJO. The aim of this study was to compare the surgical and functional outcomes of three different approaches, namely, open, conventional laparoscopy, and robotic pyeloplasty. Material and Methods. 60 patients underwent minimally invasive pyeloplasty (30 conventional laparoscopies and 30 robotics) for congenital PUJO at a tertiary health center in India. Demographic, perioperative, and postoperative data were prospectively collected and analyzed. The data of these patients were retrospectively compared with another cohort of 30 patients who had undergone open pyeloplasty. Results. There was significant difference in operative time, time to drain removal, hospital stay, pain score, and complications rate between open and minimally invasive pyeloplasty (P < 0.05). SFI was considerably lesser in robotic as compared to conventional laparoscopy. The success rate in OP, CLP, and RP was 93.33, 96.67, and 96.67%. Conclusion. Robotic pyeloplasty is safe, effective, and feasible. It is associated with significantly lesser operative time, lesser blood loss, less pain, shorter hospital stay, and fewer complications. It is also associated with considerably lesser surgeon fatigue as compared to conventional laparoscopy pyeloplasty. PMID:24624138

Lymphedema of the penis and scrotum, regardless of its etiology, is determined by reduced lymphatic flow with subsequent enlargement of the penis and scrotum. The clinical course of this condition is characterized by extreme discomfort for patients, with limitation of local hygiene, ambulation, sexual intercourse, and voiding in the standing position. The purpose of the present study is to present the experience and results of the treatment of lymphedema of the penis and scrotum by removing affected tissues and correcting the penoscrotal region. Seventeen patients with lymphedema of the penis and scrotum were treated with a modified Charles procedure, which consists of the excision of the affected skin followed by scrotoplasty and midline suture simulating the scrotal raphe. The penis is covered with a split-thickness skin graft by means of a zigzag suture on its ventral surface. Regression of symptoms and improvement of previous clinical conditions were verified in the follow-up which ranged from 6 months to 6 years. One patient who had undergone lymphadenectomy with radiation therapy due to penile cancer had recurrent scrotum lymphedema. The modified Charles procedure for the treatment of penoscrotal lymphedema is easily reproducible and allows better local hygiene, easier ambulation, voiding in the standing position, resuming sexual intercourse, and finally, better cosmetic results in the affected area with remarkable improvement in quality of life.

OBJECTIVE The objective of this study was to evaluate the clinical efficacy of posterior-only surgical correction of dystrophic scoliosis in patients with neurofibromatosis Type 1 (NF1) using a multiple anchor point method (MAPM). METHODS From 2005 to 2014, 31 patients (mean age 13.5 years old, range 10-22 years old) suffering from dystrophic scoliosis associated with NF1 underwent posterior-only surgical correction using a MAPM. The apex of the deformity was thoracic (n = 25), thoracolumbar (n = 4), and lumbar (n = 2). The mean preoperative coronal Cobb angle was 69.1° (range 48.9°-91.4°). The mean Cobb angle on the side-bending radiograph of the convex side was 58.2° (range 40°-79.8°). The mean flexibility and apical vertebral rotation (AVR) were 15.6% (range 8.3%-28.2%) and 2.5° (range 2°-3°), respectively. The mean angle of sagittal kyphosis was 58.3° (range 34.1°-79.6°). RESULTS The mean follow-up period was 53 months (range 12-96 months). The mean postoperative coronal Cobb angle was 27.4° (range 16.3°-46.7°). Postoperatively, the mean AVR and angle of sagittal kyphosis were 1.2° (range 1°-2°) and 22.4° (range 4.2°-36.3°), respectively. All patients showed good correction of all indices postoperatively. The mean postoperative correction rate was 58.7% (range 46.3%-74.1%). At the final follow-up evaluation, the corrective loss rate of the Cobb angle was only 2.3%. Only 1 patient required revision surgery. No severe complications such as spinal cord, neural, or large vascular injury occurred during the operation. CONCLUSIONS Posterior-only surgical correction of dystrophic scoliosis in patients with NF1 using a MAPM could yield satisfactory clinical efficacy of correction and fusion.

Purpose To analyze the utility of a quantitative uncertainty analysis approach for evaluation and comparison of various MRI findings for lateralization of epileptogenicity in mesial temporal lobe epilepsy (mTLE), including novel diffusion-based analyses. Methods We estimated the hemispheric variation uncertainty (HVU) of hippocampal T1 volumetry and FLAIR (Fluid Attenuated Inversion Recovery) intensity. Using diffusion tensor images of 23 nonepileptic subjects, we estimated the HVU levels of mean diffusivity (MD) in the hippocampus, and fractional anisotropy (FA) in the posteroinferior cingulum and crus of fornix. Imaging from a retrospective cohort of 20 TLE patients who had undergone surgical resection with Engel class I outcomes was analyzed to determine whether asymmetry of preoperative volumetrics, FLAIR intensities, and MD values in hippocampi, as well as FA values in posteroinferior cingula and fornix crura correctly predicted laterality of seizure onset. Ten of the cohort had pathologically proven mesial temporal sclerosis (MTS). Seven of these patients had undergone extra-operative electrocorticography (ECoG) for lateralization or to rule out extra-temporal foci. Results HVU was estimated to be 3.1 × 10−5 for hippocampal MD, 0.027 for FA in posteroinferior cingulum, 0.018 for FA in crus of fornix, 0.069 for hippocampal normalized volume, and 0.099 for hippocampal normalized FLAIR intensity. Using HVU analysis, a higher hippocampal MD value, lower FA within the posteroinferior cingulum and crus of fornix, shrinkage in hippocampal volume, and higher hippocampal FLAIR intensity were observed beyond uncertainty on the side ipsilateral to seizure onset for 10, 10, 9, 9, and 10 out of 10 pathology-proven MTS patients, respectively. Considering all 20 TLE patients, these numbers were 18, 15, 14, 13, and 16, respectively. However, consolidating lateralization results of HVU analysis on these quantities by majority voting detected the epileptogenic side for 19 out of 20 cases with no wrong lateralization. Conclusion The presence of MTS in TLE patients is associated with an elevated MD value in the ipsilateral hippocampus and a reduced FA value in the posteroinferior subregion of the ipsilateral cingulum and crus of ipsilateral fornix. When considering all TLE patients, among the mentioned biomarkers the hippocampal MD had the best performance with true detection rate of 90% without any wrong lateralization. The proposed uncertainty based analyses hold promise for improving decision-making for surgical resection. PMID:24857759

To compare nonsurgical and surgical procedures for creation of a neovagina in women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome in terms of sexual satisfaction. We report a cross-sectional study of 91 women with MRKH syndrome undergoing a neovagina creation procedure. They were members of the French National Association of Women with MRKH syndrome. We analyzed all answers to a questionnaire mailed to each woman. The questionnaire solicited short answers concerning the diagnosis and the neovagina procedure, and included the standardized FSFI (Female Sexual Function Index) questionnaire. All analyses were performed using the chi-squared test and Student's t-test. A p-value of <0.05 was considered statistically significant. Forty women answered the questionnaire. Twenty had been treated by Frank's method (non-surgical group) and 20 had undergone a surgical procedure, sigmoid vaginoplasty (12 cases) or Davidov's technique (8 cases) (surgical group). The mean time after neovagina creation was 7 years (range 1-44 years). The population characteristics did not differ significantly between the nonsurgical and surgical groups. The total FSFI score indicated good and similar functional results in the two groups (25.3±7.5 versus 25.3±8.0). Functional sexual outcomes after nonsurgical and surgical methods were similar. Therefore, the Frank's method should be proposed as first line therapy because it is less invasive than surgical procedures. In the case of failure of this technique or of refusal by the patient, surgical reconstruction may then be offered. Copyright © 2013. Published by Elsevier Ireland Ltd.

Application of a Compact High-Definition Exoscope for Illumination and Magnification in High-Precision Surgical Procedures.

Krishnan, Kartik G; Schöller, Karsten; Uhl, Eberhard

2017-01-01

The basic necessities for surgical procedures are illumination, exposure, and magnification. These have undergone transformation in par with technology. One of the recent developments is the compact magnifying exoscope system. In this report, we describe the application of this system for surgical operations and discuss its advantages and pitfalls. We used the ViTOM exoscope mounted on the mechanical holding arm. The following surgical procedures were conducted: lumbar and cervical spinal canal decompression (n = 5); laminotomy and removal of lumbar migrated disk herniations (n = 4); anterior cervical diskectomy and fusion (n = 1); removal of intraneural schwannomas (n = 2); removal of an acute cerebellar hemorrhage (n = 1); removal of a parafalcine atypical cerebral hematoma caused by a dural arteriovenous fistula (n = 1); and microsutures and anastomoses of a nerve (n = 1), an artery (n = 1), and veins (n = 2). The exoscope offered excellent, magnified, and brilliantly illuminated high-definition images of the surgical field. All surgical operations were successfully completed. The main disadvantage was the adjustment and refocusing using the mechanical holding arm. The time required for the surgical operation under the exoscope was slightly longer than the times required for a similar procedure performed using an operating microscope. The magnifying exoscope is an effective and nonbulky tool for surgical procedures. In visualization around the corners, the exoscope has better potential than a microscope. With technical and technologic modifications, the exoscope might become the next generation in illumination, visualization, exposure, and magnification for high-precision surgical procedures.

Forty-nine women with apparent Stage 1 and 2 ovarian carcinoma received intraperitoneal phosphate 32 as the only adjuvant therapy after primary surgery. In addition to bilateral salpingo-oophorectomy, 40 (82%) had analysis of peritoneal cytology, and 35 (71%) underwent omentectomy. Random peritoneal biopsies and retroperitoneal lymph node sampling were not done in any of these patients. The overall and disease-free survival rates were 86% and 75%, respectively, with no significant differences by stage, histologic grade, histologic type, or low-risk versus high-risk subsets recognized in patients who received comprehensive surgical staging. Seven (58%) of 12 patients had lymph node metastasis as themore » first site of recurrence, including two of three with late recurrences. Significant morbidity related to intraperitoneal chromic phosphate (32P) occurred in one (2%) woman. These results emphasize the need for comprehensive surgical staging of women with apparent early ovarian carcinoma to aid in the selection of appropriate initial adjuvant therapy.« less

Treatment options for trigeminal neuralgia (TN) must be customized for the individual patient, and physicians must be aware of the medical, surgical, and radiation treatment modalities to prescribe optimal treatment courses for specific patients. The following case illustrates the potential for gamma knife radiosurgery (GKRS) to be repeated multiple times for the purpose of achieving facial pain control in cases of TN that have been refractory to other medical and surgical options, as well as prior GKRS. The patient described failed to achieve pain control with initial GKRS, as well as medical and surgical treatments, but experienced significant pain relief for a period of time with a second GKRS procedure and later underwent a third procedure. Only a small subset of patients have reportedly undergone more than two GKRS for TN; thus, further research and long-term clinical followup will be valuable in determining its usefulness in specific clinical situations.

A number of surgery practice models have been developed to address general and trauma surgeon workforce shortages and on-call issues and to improve surgeon satisfaction. These include the creation of acute or urgent care surgery services and "surgical hospitalist" programs. To date, no practice models corresponding to those developed for general and trauma surgeons have been proposed to address these same issues among vascular surgeons or other surgical subspecialists. In 2003, our practice established a Vascular Surgery Hospitalist program. Since its inception nearly a decade ago, it has undergone several modifications. We reviewed hospital administrative databases and surveys of faculty, residents, and patients to evaluate the program's impact. Benefits of the Vascular Surgery Hospitalist program include improved surgeon satisfaction, resource utilization, timeliness of patient care, communication among referring physicians and ancillary staff, and resident teaching/supervision. Elements of this program may be applicable to a variety of surgical subspecialty settings. Copyright © 2013 Society for Vascular Surgery. Published by Mosby, Inc. All rights reserved.

Surgical Management of Stones: New Technology

PubMed Central

Matlaga, Brian R.; Lingeman, James E.

2011-01-01

In recent years, the surgical treatment of kidney stone disease has undergone tremendous advances, many of which were possible only as a result of improvements in surgical technology. Rigid intracorporeal lithotrites, the mainstay of percutaneous nephrolithotomy, are now available as combination ultrasonic and ballistic devices. These combination devices have been reported to clear a stone burden with much greater efficiency than devices that operate by either ultrasonic or ballistic energy alone. The laser is the most commonly used flexible lithotrite; advances in laser lithotripsy have led to improvements in the currently utilized Holmium laser platform, as well as the development of novel laser platforms such as Thulium and Erbium devices. Our understanding of shock wave lithotripsy (SWL)has been improved over recent years as a consequence of basic science investigations. It is now recognized that there are certain maneuvers with SWL that the treating physician can do that will increase the likelihood of a successful outcome while minimizing the likelihood of adverse treatment-related events.

2017-08-01

The surgical treatment of malunions after midshaft clavicle fractures is associated with a number of potential complications and the surgical procedure is challenging. However, with appropriate and meticulous preoperative surgical planning, the surgical correction yields satisfactory results. The purpose of this study was to provide a guideline and detailed overview for the computer-assisted planning and 3-dimensional (3D) correction of malunions of the clavicle. The 3D bone surface models of the pathologic and contralateral sides were created on the basis of computed tomography data. The computer-assisted assessment of the deformity, the preoperative plan, and the design of patient-specific guides enabling compression plating are described. We demonstrate the benefit and versatility of computer-assisted planning for corrective osteotomies of malunions of the midshaft clavicle. In combination with patient-specific guides and compression plating technique, the correction can be performed in a more standardized fashion. We describe the determination of the contact-optimized osteotomy plane. An osteotomy along this plane facilitates the correction and enlarges the contact between the fragments at once. We further developed a technique of a stepped osteotomy that is based on the calculation of the contact-optimized osteotomy plane. The stepped osteotomy enables the length to be restored without the need of structural bone graft. The application of the stepped osteotomy is presented for malunions of the clavicle with shortening and excessive callus formation. The 3D preoperative planning and patient-specific guides for corrective osteotomies of the clavicle may help reduce the number of potential complications and yield results that are more predictable.

Surgical correction of frontoethmoidal meningoencephalocele, although rare, is still challenging to neurosurgeons and plastic reconstructive surgeons. It is fundamental to establish reliable and safe surgical techniques. The twenty-first century has brought great advances in medical technology, and the 3D models can mimic the correct tridimensional anatomical relation of a tissue organ or body part. They allow both tactile and spatial understanding of the lesion and organ involved. The 3D printing technology allows the preparation for specific surgery ahead of time, planning the surgical approach and developing plans to deal with uncommon and high-risk intraoperative scenarios. The present report describes a case of frontoethmoidal encephalocele, (nasofrontal subtype) of a 19-month-old girl, whose surgical correction was planned using 3D printing modeling. The 3D model allowed a detailed discussion of the aspects of the surgical approach by having tissues of different consistencies and resistances, and also predicting with millimetric precision the bilateral orbitotomy measurements. Moreover, it was a fundamental and valuable factor in the multidisciplinary preoperative discussion. This approach allowed reducing the time of surgery, accurately planning the location of the osteotomies and precontouring the osteosynthesis material. 3D models can be very helpful tools in planning complex craniofacial operative procedures.

Valvular heart disease is the common cardiac manifestation of systemic lupus erythematosus (SLE) with a tendency for mitral valve regurgitation. In this study we report a case of mitral valve replacement for mitral stenosis caused by Libman-Sacks endocarditis in the setting of SLE. In addition, we provide a systematic review of the literature on mitral valve surgery in the presence of Libman-Sacks endocarditis because its challenge on surgical options continues. Surgical decision depends on structural involvement of mitral valve and presence of active lupus nephritis and antiphospholipid antibody syndrome. Review of the literature has also shown that outcome is good in most SLE patients who have undergone valvular surgery, but association of antiphospholipid antibody syndrome with SLE has negative impact on the outcome.

Oral potassium supplementation in surgical patients.

PubMed

Hainsworth, Alison J; Gatenby, Piers A

2008-08-01

Hospital inpatients are frequently hypokalaemic. Low plasma potassium levels may cause life threatening complications, such as cardiac arrhythmias. Potassium supplementation may be administered parenterally or enterally. Oral potassium supplements have been associated with oesophageal ulceration, strictures and gastritis. An alternative to potassium salt tablets or solution is dietary modification with potassium rich food stuffs, which has been proven to be a safe and effective method for potassium supplementation. The potassium content of one medium banana is equivalent to a 12 mmol potassium salt tablet. Potassium supplementation by dietary modification has been shown to be equally efficacious to oral potassium salt supplementation and is preferred by the majority of patients. Subsequently, it is our practice to replace potassium using dietary modification, particularly in surgical patients having undergone oesophagogastrectomy or in those with peptic ulcer disease.

To determine the accuracy of cytologic diagnosis, compared with histologic diagnosis, in determination of disease in ultrasound-guided fine-needle aspirates of splenic lesions. Retrospective study. Splenic specimens from 29 dogs and 3 cats. Records were searched for dogs and cats that had undergone ultrasound-guided splenic aspiration. Criteria for inclusion were ultrasonographic identification of splenic lesions and cytologic and histologic evaluation of tissue from the same lesion. Cytologic samples were obtained by fine-needle aspiration, and histologic specimens were obtained via surgical biopsy, ultrasound-guided biopsy, or necropsy. Cytologic diagnoses corresponded with histologic diagnoses in 19 of 31 (61.3%) cases and differed in 5 of 31(16.1%) cases, and 1 aspirate was inadequate for evaluation. In 7 of 31 (22.6%) cases, histologic evaluation of tissue architecture was required to distinguish between reactive and neoplastic conditions. On the basis of histologic diagnosis in 14 animals with nonneoplastic conditions, the cytologic diagnosis was correct in 11 cases, not definitive in 2 cases, and incorrect in 1 case. In 17 animals with malignant neoplastic diseases, the cytologic diagnosis was correct in 8 cases, not definitive but consistent with possible neoplasia in 5 cases, and incorrect in 4 cases. Multiple similar-appearing nodules were significantly associated with malignancy, whereas single lesions were more often benign. Ultrasound-guided aspiration of splenic lesions is a minimally invasive tool for obtaining specimens for cytologic evaluation. Although cytologic diagnoses often reflect histologic results, if missampling or incomplete sampling occurs or tissue architecture is required to distinguish between reactive and neoplastic conditions, accurate diagnosis with fine-needle aspiration may not be possible.

Laser in situ keratomileusis (LASIK) is the most common and popular procedure performed for the correction of refractive errors in the last two decades. We report a case of traumatic flap displacement with flap folding which occurred 3 years after LASIK was performed. Previous literature suggests that vision prognosis would be closely related to proper and prompt management of traumatic flap displacement with flap folding 3 years after LASIK. A 23-year-old female presented to our hospital who had undergone uneventful LASIK in both eyes 3 years prior. Unfortunately, she had suffered a blunt trauma in her right eye in a car accident. A late onset of corneal flap displacement was found with upper and lower portion of the flap being folded inside the corneal bed. Surgical intervention for debridement with subsequent reposition of corneal flap was performed as soon as possible in the operating room. A bandage contact lens was placed, and topical antibiotic and corticosteroids were given postoperatively. Two days after the operation, the displaced corneal flap was found to be well attached smoothly on the corneal bed without folds. The best-corrected visual acuity was 6/6 with refraction of -0.75 D to 1.0 D ×175° in her right eye 1 month later. We reviewed a total of 19 published cases of late-onset traumatic flap dislocations or displacements after LASIK with complete data from 2000 to 2014. Traumatic displacement of corneal flaps after LASIK may occur after blunt injury with specific direction of force to the flap margin, especially tangential one. According to the previous literature, late-onset traumatic flap displacement may happen at any time after LASIK and be caused by various types of injuries. Fortunately, good visual function could mostly be restored with immediate and proper management.

To investigate the short-term psychological function of opiate addicts who have undergone ablative stereotactic surgery targeting the nucleus accumbens (NAc) for alleviating opiate drug psychological dependence. The psychological functional status of 14 opiate addicts was assessed by standardized psychological tests both before and approximately 3 months after stereotactic surgery. Standardized tests included the Wechsler Adult Intelligence Scale-Revised Chinese (WAIS-RC), the Clinical Memory Scale of Chinese (CMS), the Eysenck Personality Questionnaire (EPQ) and the Symptom Checklist 90 (SCL-90). The evaluation of psychological dimensions included intelligence, memory, personality characteristics and mental health symptoms. Compared with the preoperative state, there was no statistically significant difference in full-scale intelligence quotient (IQ) postoperatively, but without Bonferroni correction a significant decline by 13.55% (p < 0.05) was observed in the Digit Symbol-Substitution subtest of WAIS-RC. The memory quotient (MQ) of CMS demonstrated a significant decline of 10.65% (p < 0.05) postoperatively. Concerning the participants' personality characteristics, a significant postoperative increase (p < 0.05) was detected in the Psychoticism (P) trait of EPQ. The mental healthy severity indexes of SCL-90 were decreased postoperatively. After Bonferroni correction, however, there was no statistical difference between pre- and postoperative results on all assessments. Although the patients' intelligence measures were not changed significantly, their short-term memory and attention appeared to decline postoperatively. In addition, there was a trend towards change in some personality characteristics postoperatively. The postoperative mental health levels of the patients increased, indicating a trend towards improvement. Stereotactic ablation of the NAc in opiate addicts may be associated with short-term negative psychological functions. Advisement regarding the safety of the new surgical modality and recommendations for further investigation are necessary. Copyright 2008 S. Karger AG, Basel.

The gram-negative bacillus Yokenella regensburgei (of the Enterobacteriaceae family) can be found in groundwater and foodstuffs, as well as the digestive tracts of insects and reptiles. Although it has been isolated from humans since its original description, it has rarely been reported as a cause of infection, and then, only in immunosuppressed patients. We report the first case of post-surgical secondary osteomyelitis due to Y. regensburgei in an immunocompetent woman who had undergone a craniotomy.

We assessed the reliability of implant placement after virtual planning of implant positions using cone-beam CT data and surgical guide templates. A total of 102 patients (250 implants, 55.4% mandibular; mean patient age, 40.4 years) who had undergone implant treatment therapy in an armed forces dental clinic (Cologne, Germany) between July 1, 2005 and December 1, 2005. They were treated with a system that allows transfer of virtual planning to surgical guide templates. Only in eight cases the surgical guides were not used because a delayed implant placement was necessary. In four posterior mandibular cases, handling was limited because of reduced interocclusal distance, requiring 50% shortening of the drill guides. The predictability of implant size was high: only one implant was changed to a smaller diameter (because of insufficient bone). In all cases, critical anatomical structures were protected and no complications were detected in postoperative panoramic radiographs. In 58.1% (147) of the 250 implants, a flapless surgery plan was realized. Implant placement after virtual planning of implant positions using cone beam CT data and surgical templates can be reliable for preoperative assessment of implant size, position, and anatomical complications. It is also indicative of cases amenable to flapless surgery.

Traumatic paralysis of the brachial plexus is an extremely disabling pathology. The type of trauma most frequently suffered by this group of patients is due to motorcycle injuries. It therefore affects a population of young patients. In the majority of cases, these patients receive compensation for permanent damage from insurance companies. Surgery of the brachial plexus enables various forms of functional recovery, depending on the number of roots of the brachial plexus involved in the injury. The aim of this study is to compare the functional deficit and the extent of the related compensation before and after surgical intervention, and to evaluate the saving in economic terms (understood as the cost of compensation paid by insurance companies) obtainable through surgical intervention. The authors analysed the functional recovery obtained through surgery in 134 patients divided into 4 groups on the basis of the number of injured roots. The levels of compensation payable to the patient before surgical intervention, and 3 years after, were then compared. The results showed that the saving obtainable through surgical treatment of brachial plexus injuries may exceed 65% of the economic value of the compensation that would have been attributable to the same patients if they had not undergone surgical treatment. © Georg Thieme Verlag KG Stuttgart · New York.

Ossified Intracranial Meningiomas: Description of the First Series of Cases and Review of the Literature.

2016-10-01

Metaplastic meningiomas are characterized by mesenchymal differentiation with formation of bone, cartilage, fat, or xanthomatous elements. However the presence of extensive areas of ossification is rare in meningiomas. In addition, intracranial location of ossified meningiomas is uncommon. Surgical management represents the optimal treatment for ossified meningiomas, but ossification may interfere with surgery and condition outcome. By reviewing patient records and contacting patients, families, and referring physicians, the following information was gathered: age, sex, tumor location, clinical presentation, preoperative and postoperative functional status, and surgical data. Each surgical specimen had been formalin-fixed, paraffin-embedded, and cut into parallel 4-μm-thick sections for histological evaluation. Our literature search identified 8 cases, all of whom had undergone surgical treatment. Histopathological analysis revealed the presence of disorganized bone spicules with solitary oval osteocytic nuclei and lined by osteoblasts, with clear evidence of bone tissue in at least 50% of tumor tissue. Here we present the largest series, to our knowledge, of surgically treated intracranial ossified meningiomas reported to date. The mechanism of ossification in these meningiomas remains unclear, and various hypotheses have been formulated. Complete lesion removal, or subtotal debulking in those cases characterized by tenacious adherences to vascular structures and/or critical areas, may represent the optimal treatment.

Intractable aspiration is a serious, often life-threatening condition due to its potential impact on pulmonary function. Aspiration requires therapeutic measures, starting with conservative management but often necessitating surgical treatment. The basic surgical principle is to separate the alimentary and respiratory tracts through a variety of procedures which, unfortunately, nearly all result in the loss of phonation, with the exception of total laryngectomy (TL) which includes the placement of an indwelling voice prosthesis. In this study, we present a modified laryngotracheal separation (LTS) technique that, we believe, offers multiple advantages compared to standard TL. After reviewing the medical records of 35 patients with intractable aspiration who have undergone LTS, we describe the surgical technique and present the postoperative result. In a second surgical procedure about two months following LTS, we aimed to achieve voice restoration by placement of an indwelling voice prosthesis. Intractable aspiration was successfully treated in all patients. Placement of an indwelling voice prosthesis during a second operation was successful in 15 patients, representing the largest reported cohort thus far. LTS is a reliable surgical technique to treat intractable aspiration, with restoration of oral intake, thereby improving the general condition and quality of life of these unfortunate patients. Furthermore, voice restoration can be achieved in selected patients, by placement of a voice prosthesis.

To our knowledge, few studies have compared complications and surgical outcomes of adolescent idiopathic scoliosis (AIS) between junior attending surgeons and senior attending surgeons. To compare surgical strategies, complications, and outcomes of posterior corrective surgery for AIS between junior attending surgeons and senior attending surgeons. According to experience level of operation surgeons, the patients were assigned to 2 groups. Group A was the "junior surgeon" group. Group B was the "senior surgeon" group. The following parameters were compared between the 2 groups: age, sex, diagnosis, hospital of record, surgeon experience level, type of instrumentation, type of screws, estimated blood loss, duration of surgery, length of fusion, correction techniques, main curve correction, and thoracic kyphosis correction. A total of 132 patients with AIS were included in group A, whereas 207 were in group B. The translational technique was used more often in group A (P < 0.05). whereas the derotation technique was used more often in group B (P < 0.05). Senior surgeons used more monoaxial screws than junior surgeons (P < 0.05). The junior group had significantly greater estimated blood loss than the senior group (P < 0.05). The senior group had significant better correction rates of severe main curve (>70°) and thoracic kyphosis than the junior group (P < 0.05). Senior attending surgeons outperformed junior surgeons in blood loss control, thoracic kyphosis correction, and correction of severe curves. Copyright © 2018 Elsevier Inc. All rights reserved.

Adults with CHD often exhibit complex cardiac abnormalities, whose management requires specific clinical and surgical expertise. To enable easier access of these patients to highly specialised care, we implemented a collaborative programme that incorporates medical and surgical specialists belonging to both paediatric and adult cardiovascular institutions. The objective of this study was to review the experience gained and to analyse the surgical outcome of major cardiac surgery. We retrospectively reviewed all consecutive patients admitted for major cardiac surgery using our network between January, 2010 and December, 2013. Analysis of surgical outcome was performed in patients selected for major cardiac surgery with cardiopulmonary bypass. Early and late outcomes were evaluated. Out of a total of 433 inward patients, 86 were selected for surgery. The median age was 25.5 years, -64 patients (74.4%) had previously undergone heart surgery, and -55 patients (64%) had been subjected to at least one sternotomy. Abnormalities of the left ventricular and right ventricular outflow tract were the most frequent (37.2% and 30.2%, respectively), and despite high-surgical complexity only one death occurred (in-hospital mortality 1.1%). On a median follow-up time of 4 years no deaths and no heart-failure events have occurred; one patient underwent further cardiac surgery programmed at the time of discharge. Low mortality and morbidity rates can be obtained in high-surgical complexity adults with CHD populations when paediatric and adult cardiac specialists operate in the same multidisciplinary environment.

Late revision or correction of facial trauma-related soft-tissue deformities.

Rieck, Kevin L; Fillmore, W Jonathan; Ettinger, Kyle S

2013-11-01

Surgical approaches used in accessing the facial skeleton for fracture repair are often the same as or similar to those used for cosmetic enhancement of the face. Rarely does facial trauma result in injuries that do not in some way affect the facial soft-tissue envelope either directly or as sequelae of the surgical repair. Knowledge of both skeletal and facial soft-tissue anatomy is paramount to successful clinical outcomes. Facial soft-tissue deformities can arise that require specific evaluation and management for correction. This article focuses on revision and correction of these soft-tissue-related injuries secondary to facial trauma. Copyright © 2013. Published by Elsevier Inc.

Repair of facial clefts implies wide tissue mobilization with multi-stage surgical treatment. Authors propose pre-surgical orthopedic correction for naso-oro-ocular clefts and a novel surgical option for Tessier No. 3 cleft. Two male infants, a Tessier No. 3 cleft (age 7 months) and another Tessier No. 4 (age 3 months), were treated with a modified orthopedic Latham device with additional septo-premaxillary molding and observed to age four years. Tessier No. 3 orthopedic measurements were obtained by image corrected cephalometric analysis. Subsequent repair included tissue expansion on Tessier No. 4 and naso-frontal Rieger flap combined with myocutaneous upper lid flap on Tessier No. 3. Orthopedic movements ranged from 18.5 mm in bi-planar to 33 mm in oblique analyses. Tissue margins became aligned with platform normalization. Tissue expansion on Tessier No. 4 improved distances from ala base-lower lid and subalar base-lip. The naso-frontal flap combined with myocutaneous upper lid flap on Tessier No. 3 had similar achievement, but also sufficiently lengthened ala base-canthal distance. Repairs were facilitated by pre-surgical orthopedic correction. The naso-frontal flap combined with an upper lid myocutaneous flap seems viable as a single-stage option to lengthen ala base-canthal distance to advance repair achievement in unilateral Tessier No. 3.

The purpose of this study was to assess the effects of surgical correction of pectus carinatum on health-related quality of life and self-esteem. Between May 2012 and May 2013, a prospective observational single-center cohort study was conducted on consecutive patients undergoing surgical correction of pectus carinatum at our institution. Patients filled in questionnaires on health-related quality of life and self-esteem before and six months after surgery. Disease-specific health-related quality of life was improved by 33% (95% CI: 23; 44%) according to responses to the Nuss Questionnaire modified for Adults. The improvement for generic mental health-related quality of life was 7% (95% CI: 3; 12%) in responses to the Short Form-36 Questionnaire. The improvement in self-esteem was 9% (95% CI: 2; 17%) as assessed with the Rosenberg Self-Esteem Scale. A Single Step Questionnaire supported the improvements in health-related quality of life and self-esteem six months postsurgery. This study confirms positive effects of surgical correction of pectus carinatum on health-related quality of life and self-esteem. Patients were to a greater extent self-satisfied about chest appearance following surgery, indicating this to be a step in the right direction toward improved body image, mental health and self-esteem.

To study the evolution of deformity of the proximal interphalangeal joint over 5 years after good surgical correction of Dupuytren-induced contracture. We assessed 63 patients (72 fingers; 69 hands) with Dupuytren disease for the degree of contracture, its correction after surgery, and the range of movement at the proximal interphalangeal joints at 3 and 6 months, and 1, 3, and 5 years after fasciectomy with or without the use of a firebreak graft. We investigated associations between the recurrence of contracture and preoperative patient and surgical factors. There were 4 patterns of evolution of contracture after surgical correction. A total of 31 patients (33 hands) showed good improvement that was maintained for 5 years (minimal recontracture group). Twenty patients (23 hands) showed good initial improvement, which mildly worsened (< 20°) but was then maintained over 5 years (mild early recontracture group). Four patients (5 hands) worsened in first 3 months after surgery (> 20°) but there was no further worsening (severe early recontracture group). Eight patients (8 hands) worsened progressively over 5 years (progressive recontracture group). Worsening of contracture more than 6° between 3 and 6 months after surgery predicted progressive recontracture at 5 years. Recurrence of contracture (not disease recurrence) could be predicted as early as 6 months after surgery for Dupuytren disease. Copyright © 2013 American Society for Surgery of the Hand.

We sought to combine parental and child reports in order to describe the behavior, self-perception, and emotional profile of children with a surgically corrected congenital heart disease (CHD). Forty-three children with a surgically corrected CHD were selected and compared to an age- and sex-matched healthy group. The parents of the CHD children completed a behavior rating scale, the Child Behavior Checklist. Children 8 years and older (n = 23) completed a self-report questionnaire concerning perceived competence, their anxiety level, and feelings of depression. Compared to parents of healthy children, those of CHD children report significantly lower school results (p < .01), more school problems in general (p < .01), and a higher percentage of their children repeated a school year (p < .01). They also reported more social (p < .01) and attention problems (p < .01) and more aggressive behavior (p < .05). On self-perception and state anxiety questionnaires, no significant differences were found between the patient group and the healthy group. On a depression scale, however, children with a surgically corrected CHD reported more depressive feelings than healthy controls (p < .01). Parents of children with CHD rate their child's school competence to be weaker than healthy peers, they report more attention and social problems and more aggressive behavior. Children themselves did not report differences on perceived competence or anxiety but they do indicate more depressive symptoms than healthy peers.

Computer-aided surgical planner for a new bone deformity correction device using axis-angle representation.

2014-11-01

Current external fixators for distraction osteogenesis (DO) are unable to correct all types of deformities in the lower limb and are difficult to use because of the lack of a pre-surgical planning system. We propose a DO system that consists of a surgical planner and a new, easy-to-setup unilateral fixator that not only corrects all lower limb deformity, but also generates the contralateral/predefined bone shape. Conventionally, bulky constructs with six or more joints (six degrees of freedom, 6DOF) are needed to correct a 3D deformity. By applying the axis-angle representation, we can achieve that with a compact construct with only two joints (2DOF). The proposed system makes use of computer-aided design software and computational methods to plan and simulate the planned procedure. Results of our stress analysis suggest that the stiffness of our proposed fixator is comparable to that of the Orthofix unilateral external fixator. We tested the surgical system on a model of an adult deformed tibia and the resulting bone trajectory deviates from the target bone trajectory by 1.8mm, which is below our defined threshold error of 2mm. We also extracted the transformation matrix that defines the deformity from the bone model and simulated the planned procedure. Copyright © 2014 IPEM. Published by Elsevier Ltd. All rights reserved.

To evaluate the basic principles of surgical correction of concealed penis. From Jan. 1999 to Dec. 2002, 63 cases of concealed penis, aged from 1 year and 6 months to 19 years with a mean age of 7 years and 2 months, were corrected with two different approaches: 37 cases of group A with obesity were corrected by anchoring micrus tissue onto the pubis at the base of the penis, and 26 cases of group B by fixing the subcutateous tissues at both sides of the penile shaft to the deep tunica albuginea at the penile root. Then prepuce plasty was carried out. Six-month postoperative follow-up found adequate exposure of the penis in all of group A, prepuce oedema in 7 cases, abdomen fat liquidization in 3 cases, unsatisfactory recovery of incision hollow in 3 cases and patchy numbness of the glans in 1 case. The 25 cases of group B had satisfactory exposure of the penis, with no obvious prepuce oedema, 1 case with retraction of the penis 7 days after operation. Various surgical procedures could be adopted for concealed penis, and the key to the satisfactory appearance is the restoration of penile tunicae and the fixation at the base of the penis. Further study is needed to determine the natural history of these disorders as well as which conditions and what age will benefit most from surgical intervention.

Retropupillary iris-claw intraocular lens for the surgical correction of aphakia in cases with microspherophakia.

This study aimed to evaluate the safety and efficacy of retropupillary fixation of an iris-claw intraocular lens (IOL; Verisyse polymethyl methacrylate IOL, Abbott Medical Optics [AMO], Netherlands) for the surgical correction of aphakia in microspherophakic eyes without sufficient capsular support. This was a prospective, interventional, noncomparative case series. This interventional case series comprised 17 eyes of 9 microspherophakic patients. Retropupillary fixation of the Verisyse iris-claw IOL (AMO) was performed in all cases. The surgical time was measured. Corrected distance visual acuity, astigmatism, intraocular pressure (IOP), tissue reaction, pigment dispersion, and stability of the IOL were studied 1 day, 3 days, 1 week, 2 weeks, 1 month, and 6 months postoperatively. Eight patients had familial microspherophakia and one patient had Marfan's syndrome. Eighty-two percent of the cases achieved a visual acuity of 0.3 or better. There was no significant postoperative inflammatory reaction. Transient elevation of IOP was recorded in two cases in the 1st week only. One IOL developed disengagement of one of the haptics from the iris and was successfully re-engaged. All the other IOLs were well centered and stable. The mean surgical time was 18.0 ± 4.5 min. Retropupillary fixation of an iris-claw IOL is a safe and effective procedure that provides early visual recovery. It is also a time-saving method for correcting aphakia in microspherophakic eyes without sufficient capsular support.

We studied all patients operated for partial anomalous pulmonary venous drainage and half-time follow-up. Twenty-eight patients with a mean age of 5 +/- 5 years (5 patients were less than 1 year old). There were sixteen male and twelve female patients. Thirteen patients were symptomatic (47%). The drainage was to the superior vena cava in thirteen cases, to the inferior vena cava in eight cases, to the right atrium in five cases, mixed (to the superior vena cava and to the inferior vena cava) in one case and to the innominate vein in one patient. The diagnosis was made through echocardiography and catheterization in 25 patients, whereas nuclear magnetic resonance was performed in the last five patients. All cases were corrected through medium thoracotomy, except for the single case in which the drainage was to the innominate vein). In 27 patients, the pulmonary veins were guided to the left atrium through an enlarged present atrial septal defect or through a created atrial septal defect. In one case a direct connection was performed from the veins to the left atrium. After the surgical correction, all patients underwent a color-coded Doppler echocardiography study and a nuclear magnetic resonance study was performed in five patients. Twenty-seven patients survived after surgical correction. The patient with a mixed drainage developed an obstruction of the superior vena cava, the pressure gradient was 9 mmHg. He required a second surgical procedure followed with angioplasty on two occasions during a six month period. Two patients showed an ectopic atrial rhythm at some late time. The patient who died was one month old and had an associated pulmonary parenchymal sequestration. Partial anomalous venous connection is a congenital heart disease which has an easy surgical correction. Complications may arise after the surgical correction, among them obstruction of the superior vena cava and arrythmias are most frequently found. Obstruction is present when 50% of the caval area is occupied by the patch. The arrythmias occur following all surgical techniques. In order to decrease the arrythmias it is necessary to perform a good hemosthasis at the site of the patch, to leave the sinus node free of compression and to perform the atrial incision at the posterior wall. The diagnosis and the follow-up can be performed with non-invasive procedures.

Non-surgical treatment for eyelid retraction in thyroid eye disease (TED).

PubMed

2017-08-09

Thyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of eyelid malposition in TED. The authors have focused on the use of hyaluronic acid, triamcinolone injections and botulinum toxin type A as non-surgical treatment alternatives, paying special attention to dosing, technique, efficacy and duration of effect. Non-surgical treatment modalities may represent viable in cases where surgical correction is not an option. Although temporary, these modalities appear to be beneficial for ocular exposure remediation, improving quality of life and broadening our therapeutic arsenal. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Surgical myotomy of the lower esophageal sphincter has a 5-year success rate of approximately 91 %. Peroral endoscopic myotomy can provide similar results for controlling dysphagia. Some patients experience either persistent or recurrent dysphagia after myotomy. We present here a retrospective analysis of our experience with redo myotomy for recurrent dysphagia in patients with achalasia. From March 1996 to February 2015, 234 myotomies for primary or recurrent achalasia were performed in our center. Fifteen patients (6.4 %) had had a previous myotomy and were undergoing surgical redo myotomy (n = 9) or endoscopic redo myotomy (n = 6) for recurrent symptoms. Patients presented at a median of 10.4 months after previous myotomy. Median preoperative Eckardt score was 6. Among the nine patients undergoing surgical myotomy, three esophageal perforations occurred intraoperatively (all repaired immediately). Surgery lasted 111 and 62 min on average (median) in the surgical and peroral endoscopic myotomy (POEM) groups, respectively. No postoperative complications occurred in either group. Median postoperative stay was 3 and 2.5 days in the surgical and POEM groups, respectively. In the surgical group, Eckardt score was <3 for seven out of nine patients after a mean follow-up of 19 months; it was <3 for all six patients in the POEM group after a mean follow-up of 5 months. A redo myotomy should be considered in patients who underwent myotomy for achalasia and presenting with recurrent dysphagia. Preliminary results using POEM indicate that the technique can be safely used in patients who have undergone previous surgical myotomy.

Surgical removal plays an important role in treating children's craniopharyngioma. For a safe and minimally invasive craniotomy, a reformed surgical modality was proposed in this paper by combining the insertion of an Ommaya reservoir system (ORS) by stereotactic puncture, aspiration of cystic fluid in 2-day interval for consecutive 7-10 days, and the delayed tumor resection. Eleven patients (aged from 5 to 9 years old) with giant cystic craniopharyngiomas who had undergone the reformed surgical modality during November 2014 and December 2015 were collected as group A. In contrast, seven patients (aged from 5 to 11 years old) who had undergone the traditional directed operation without any prior management from January 2014 to October 2014 were collected into group B. A retrospective analysis was performed for both groups at one institution. The preoperative and postoperative clinical presentations, neuroimaging, early postoperative outcome, and the surgery-related complications of both groups were reviewed. For group A, the mean value of the maximum tumor diameters shank from 52.36 to 23.82 mm after implementing aspiration of the cystic fluid in 1-day interval for consecutive 8.23 days. Eight patients (72.73%) in group A underwent a gross total resection (GTR), while two (28.57%) patients underwent GTR in group B. The postoperative electrolyte disturbance rate and endocrine disorder rate of group B were significantly higher than those of group A (42.86 vs 36.36%; 71.43 vs 45.45%). Postoperative long-term diabetes insipidus only occurred in one patient of group B, and postoperative visual deterioration occurred in two patients of group B. Besides, one patient of group B died of severe postoperative hypothalamus dysfunction. Patients with residual tumors were applied with additional adjuvant radiotherapy, and no recurrence was observed in follow-up examinations. A favorable outcome can be achieved by combining the insertion of an ORS by stereotactic puncture, aspiration of cystic fluid in 2-day interval for continuously 7-10 days, and the delayed tumor resection. This combined treatment modality maybe an effective method to treat children with giant cystic craniopharyngiomas.

Voice tuning with new instruments for type II thyroplasty in the treatment of adductor spasmodic dysphonia.

PubMed

2016-10-01

Adductor spasmodic dysphonia is a rare voice disorder characterized by strained and strangled voice quality with intermittent phonatory breaks and adductory vocal fold spasms. Type II thyroplasty differs from previous treatments in that this surgery does not involve any surgical intervention into the laryngeal muscle, nerve or vocal folds. Type II thyroplasty intervenes in the thyroid cartilage, which is unrelated to the lesion. This procedure, conducted with the aim of achieving lateralization of the vocal folds, requires utmost surgical caution due to the extreme delicacy of the surgical site, critically sensitive adjustment, and difficult procedures to maintain the incised cartilages at a correct position. During surgery, the correct separation of the incised cartilage edges with voice monitoring is the most important factor determining surgical success and patient satisfaction. We designed new surgical instruments: a thyroid cartilage elevator for undermining the thyroid cartilage, and spacer devices to gauge width while performing voice monitoring. These devices were designed to prevent surgical complications, and to aid in selecting the optimal size of titanium bridges while temporally maintaining a separation during voice monitoring. We designed new surgical instruments, including a thyroid cartilage elevator and spacer devices. Precise surgical procedures and performing voice tuning during surgery with the optimal separation width of the thyroid cartilage are key points for surgical success. We introduce the technique of voice tuning using these surgical tools in order to achieve a better outcome with minimal surgical complications. Copyright © 2016 Elsevier Ireland Ltd.

Surgical treatment for severe circumferentially fixed cervical kyphosis has been challenging. Both anterior and posterior releases are necessary to provide the cervical mobility necessary for fusion in a corrected position. In two case reports, we describe the circumferential osteotomy of anterior-posterior-anterior surgical sequence, and the efficacy of this technique when cervical pedicle screw fixation for severe fixed cervical kyphosis is used. Etiology of fixed cervical kyphosis was unknown in one patient and neurofibromatosis in one patient. Both patients had severe fixed cervical kyphosis as determined by cervical radiographs and underwent circumferential osteotomy and fixation via an anterior-posterior-anterior surgical sequence and correction of kyphosis by pedicle screw fixation. Severe fixed cervical kyphosis was treated successfully by the use of circumferential osteotomy and pedicle screw fixation. The surgical sequence described in this report is a reasonable approach for severe circumferentially fixed cervical kyphosis and short segment fixation can be achieved using pedicle screws.

2017-04-28

Pelvic organ prolapse affects approximately 8% of women, and the demand for pelvic organ prolapse surgery is expected to increase by nearly 50% over the next 40 years. The surgical techniques used to correct pelvic organ prolapse have evolved over the last 10 years, with multiple well-designed studies addressing the risks, outcomes, reoperation rates, and optimal surgical approaches. Here we review the most recent evidence on the route of access, concomitant procedures, and synthetic materials for augmenting the repair. Ultimately, this review highlights that there is no optimal method for correcting pelvic organ prolapse and that the risks, benefits, and approaches should be discussed in a patient-centered, goal-oriented approach to decision-making.

[Tetralogy of Fallot associated with left atrial isomerism].

Ferrín, L M; Atik, E; Aiello, V; Marcial, M B; Ebaid, M

1996-10-01

The association of tetralogy of Fallot with atrial isomerism has been rarely reported. Eight cases (five with left isomerism and three with right isomerism) are known. This paper reports two other cases of tetralogy of Fallot with left atrial isomerism. The syndrome's defects were disguised and without clinical expression because of the presence of the right ventricular outlet obstruction of tetralogy of Fallot. These diagnostic elements, not recognized in one of the patients previous to surgical correction of tetralogy of Fallot, were present: junctional rhythm, bronchial isomerism, partial anomalous pulmonary vein connection, agenesy of inferior vena cava and abdominal heterotaxy; their identification previous to surgical correction of tetralogy of Fallot, is necessary for an adequate surgical management.

Boston keratoprosthesis (KPro) type I is a technique to treat patients with corneal diseases that are not amenable to conventional keratoplasty. Correct assembly and central implantation of the prosthesis are crucial for postoperative visual recovery. This study investigates the potential benefit of intraoperative optical coherence tomography (OCT) to monitor KPro surgery. Retrospective case series are presented for two patients who underwent Boston KPro type I implantation. The surgery in both patients was monitored intraoperatively using a commercially available intraoperative OCT (iOCT) device mounted on a surgical microscope. Microscope-integrated intraoperative OCT was able to evaluate the correct assembly and implantation of the KPro. All parts of the prosthesis were visible, and interfaces between the corneal graft and titanium backplate or anterior optics were clearly depictable. Moreover, iOCT visualized a gap between the backplate and graft in one case, and in the other case, a gap between the anterior optic and graft. Neither gap was visible with a conventional surgical microscope. The gap between the anterior optic and the graft could easily be corrected. Microscope-integrated iOCT delivers enhanced information, adding to the normal surgical microscope view during KPro surgery. Correct assembly can be controlled as well as the correct placement of the Boston KPro into the anterior chamber.

Variation in practice: an analysis of Scottish Surgical Profiles ENT data.

Yeo, J C L; Ah-See, K W; Mackenzie, K

2013-02-01

Variation in otolaryngology intervention rates is reported in the Scottish Surgical Profiles Project. Tonsillectomy is one of the selected key indicator procedures. The variation in practice was discussed nationally at the Scottish Otolaryngology Society summer meetings in 2009 and 2010. NHS Grampian had a significantly higher tonsillectomy rate compared with other Scottish NHS boards. To determine the accuracy of NHS Grampian data reported by the Information Service Division (ISD) and to record the appropriateness of listing of patients for tonsillectomy with reference to the Scottish Intercollegiate Guidelines Network (SIGN). Retrospective review of case notes and surgical records of patients who had undergone tonsillectomy between March 2007 and March 2008 in NHS Grampian. Between March 2007 and March 2008, 509 tonsillectomy cases were performed in NHS Grampian. This corresponded to the data received from ISD. 87% of tonsillectomies performed were compliant with SIGN guidelines. The Scottish otolaryngology clinicians have found the reporting of the intervention rates stimulating and challenging. Discussion of the surgical profile project regularly at national specialty meetings resulted in a preliminary detailed targeted audit of those who were persistent outliers for tonsillectomy. This refuted the presumed reasons for this variation, namely inaccurate figures from ISD and inappropriate listings by clinicians.

To evaluate the surgical management of obstructive sleep apnea in children with cerebral palsy. Retrospective review of 27 children with cerebral palsy who underwent surgical treatment for obstructive sleep apnea. Charts were reviewed. Data gathered included primary complaint, coexisting illnesses, initial procedure performed, age at initial surgery, number of days the child was monitored postoperatively in the intensive care unit, notation of postoperative respiratory distress and management, and outcome. Nineteen children underwent adenotonsillectomy for initial treatment of obstructive sleep apnea. Three of these children also had a uvulectomy. Six children had an adenoidectomy alone as their initial procedure. Neither uvulopalatopharyngoplasty nor tracheostomy was performed as an initial procedure. Mean follow-up was 34 months. Seventy-six percent of these children have not required any further surgery. Of the six children who have undergone further surgery, one has required a revision adenoidectomy, and another underwent a tonsillectomy and uvulectomy 2 months after the initial adenoidectomy. Four children ultimately required a tracheotomy. Eighty-four percent of these children were successfully managed without a tracheotomy. We recommend tonsillectomy and/or adenoidectomy for initial surgical treatment of obstructive sleep apnea in children with cerebral palsy.

Surgery is an effective treatment in severe cases of supraglottic exercise-induced laryngeal obstruction (E-ILO). Conservatively treated subjects and subjects tested negative for E-ILO, who still experience breathing problems 1-3 years after diagnosis, tend to adjust their physical activity to a greater extent than surgically treated subjects. To investigate how symptoms and level of physical activity change over time in patients with E-ILO who have undergone surgery, patients with E-ILO treated conservatively and patients who tested negative for laryngeal obstruction at continuous laryngoscopy exercise-test (CLE-test). Patients referred for exercise-induced breathing difficulties answered questionnaires at diagnostic CLE-test and at follow-up. Questions regarded exercise-induced breathing problems, current physical activity level, and medical history of asthma and perennial allergy. Out of 84 invited subjects, 59 (70%) answered both questionnaires. Surgically treated subjects had less breathing problems at follow-up compared with conservatively treated subjects and subjects who tested negative (p < 0.001). None of the surgically treated subjects were less physically active or had changed sport due to exercise-induced dyspnoea, whereas 41.7% of the conservatively treated subjects had made such adjustments (p < 0.001).

To describe the outcomes of patients who have undergone well-conducted surgery and found to have Stage 1 serous uterine cancer. This retrospective cohort study includes women who have been treated for Stage 1 serous cancer of the uterus from 1985 to 2001. Cases were included from the regional cancer centers in Hamilton, London, Sunnybrook Toronto and Cancer Care Manitoba. Forty-three women met the inclusion criteria: Complete surgical staging (n = 27), surgery followed by pelvic radiation therapy (n = 4), surgery followed by whole abdominal radiation therapy (n = 6), surgery followed by adjuvant chemotherapy (n = 6). Patient age or depth of invasion did not influence survival. Progression free interval was 22 months (SD = 14.29). Recurrence rate was highest for adjuvant chemotherapy (66%). Survival was assessed by treatment modality and a statistically significant poorer survival was seen in the adjuvant chemotherapy group (OR 17.5; 95% CI 1.3-227.6). No comment can be made on a superior treatment regimen given the small numbers in each treatment strata. This study supports the findings of others in the literature. In a group of patients where surgical staging shows limited disease (i.e., surgically Stage 1 disease), then surgery alone appears to be adequate treatment.

Excimer and femtosecond lasers are widely used in ophthalmology to correct refraction. Laser systems for vision correction are based on versatile technical solutions and include multiple hard- and software components. Laser characteristics, properties of laser beam delivery system, algorithms for cornea treatment, and methods of pre-surgical diagnostics determine the surgical outcome. Here we describe the scientific and technological basis for laser systems for refractive surgery developed at the Physics Instrumentation Center (PIC) at the Prokhorov General Physics Institute (GPI), Russian Academy of Sciences.

Paredes, Alfredo A; Williams, J Kerwin; Elsahy, Nabil I

2002-04-01

The constricted ear may be described best as a pursestring closure of the ear. The deformity may include lidding of the upper pole with downward folding, protrusion of the concha, decreased vertical height, and low ear position relative to the face. The goals of surgical correction should include obtaining symmetry and correcting the intra-auricular anatomy. The degree of intervention is based on the severity of the deformity and may range from simple repositioning, soft tissue rearrangement, or manipulation of the cartilage. Multiple surgical techniques are described.

2012-01-01

Background and Objectives: Conversion to open surgery is an important problem, especially during the learning curve of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. Methods: Here, we discuss conversion to the Stoppa procedure during laparoscopic TEP inguinal hernia repair. Outcomes of patients who underwent conversion to an open approach during laparoscopic TEP inguinal hernia repair between September 2004 and May 2010 were evaluated. Results: In total, 259 consecutive patients with 281 inguinal hernias underwent laparoscopic TEP inguinal hernia repair. Thirty-one hernia repairs (11%) were converted to open conventional surgical procedures. Twenty-eight of 31 laparoscopic TEP hernia repairs were converted to modified Stoppa procedures, because of technical difficulties. Three of these patients underwent Lichtenstein hernia repairs, because they had undergone previous surgeries. Conclusion: Stoppa is an easy and successful procedure used to solve problems during TEP hernia repair. The Lichtenstein procedure may be a suitable option in patients who have undergone previous operations, such as a radical prostatectomy. PMID:23477173

2010-09-01

Hemangiopericytomatous pattern is characteristic of hemangiopericytoma/solitary fibrous tumor (HPC/SFT) and certain histological features might indicate a malignant potential, but the behavior of HPC/SFT is unpredictable. Endobronchial ultrasound (EBUS) is a useful diagnostic device in that the ultrasonographic image can be viewed and the EBUS-transbronchial needle aspiration can obtain a biopsied sample. We herein report a patient undergoing multiple surgical resections of recurrent HPC/SFT. A 74-year-old man had undergone right upper lobectomy for HPC/SFT 15 years ago. He received a partial resection of the left lung and a resection of the anterior mediastinal mass for its recurrences 13 years and six years ago, respectively. He had also undergone surgery for gastric carcinoma two years ago. He then presented with a tumor measuring 3 x 4 cm in the subcarinal area. Preoperative EBUS revealed a tumor with abundant thin-walled vessel-like structures, which was consistent with HPC/SFT. The tumor was completely resected and was finally diagnosed as low-grade malignant HPC/SFT.

Effectiveness of the surgical safety checklist in correcting errors: a literature review applying Reason's Swiss cheese model.

Collins, Susan J; Newhouse, Robin; Porter, Jody; Talsma, AkkeNeel

2014-07-01

Approximately 2,700 patients are harmed by wrong-site surgery each year. The World Health Organization created the surgical safety checklist to reduce the incidence of wrong-site surgery. A project team conducted a narrative review of the literature to determine the effectiveness of the surgical safety checklist in correcting and preventing errors in the OR. Team members used Swiss cheese model of error by Reason to analyze the findings. Analysis of results indicated the effectiveness of the surgical checklist in reducing the incidence of wrong-site surgeries and other medical errors; however, checklists alone will not prevent all errors. Successful implementation requires perioperative stakeholders to understand the nature of errors, recognize the complex dynamic between systems and individuals, and create a just culture that encourages a shared vision of patient safety.

In the surgical treatment of spinal dural arteriovenous fistulas (DAVFs), intraoperative definition of anatomic characteristics of the DAVF and identification of the fistulous point is mandatory to effectively exclude the DAVF. Intraoperative ultrasound and contrast-enhanced ultrasound integrated with color Doppler ultrasound was applied in the surgical setting for a cervical DAVF to identify the fistulous point and evaluate correct occlusion of the fistula. Integration of intraoperative ultrasound and contrast-enhanced ultrasound is a simple, cost-effective technique that provides an opportunity for real-time dynamic visualization of DAVF vascular patterns, identification of the fistulous point, and assessment of correct exclusion. Compared with other intraoperative tools, such as indocyanine green videoangiography, it allows the surgeon to visualize hidden anatomic and vascular structures, minimizing surgical manipulation and guiding the surgeon during resection.

2011-01-01

BACKGROUND: This study was carried out to analyze the relationship between clinical factors and velopharyngeal closure (VPC) in cleft palate patients. METHODS: Chi-square test was used to compare the postoperative velopharyngeal closure rate. Logistic regression model was used to analyze independent variables associated with velopharyngeal closure. RESULTS: Difference of postoperative VPC rate in different cleft types, operative ages and surgical techniques was significant (P=0.000). Results of logistic regression analysis suggested that when operative age was beyond deciduous dentition stage, or cleft palate type was complete, or just had undergone a simple palatoplasty without levator veli palatini retropositioning, patients would suffer a higher velopharyngeal insufficiency rate after primary palatal repair. CONCLUSIONS: Cleft type, operative age and surgical technique were the contributing factors influencing VPC rate after primary palatal repair of cleft palate patients. PMID:22279464

Two patients with penile carcinoma are presented after management at a district hospital in Kenya. Both had undergone ritual circumcision as teenagers and presented late. HR was a 73 year old who presented with a fungating penile mass for which a partial penectomy was performed after wedge biopsy confirmed malignancy. He thereafter declined to have the surgical specimen sent for histology and took the amputated stump for burial in his compound to avoid bad omen. GK was 25 years old and presented with a fungating mass and underwent partial penectomy after a histological diagnosis was made. He absconded from follow-up after being informed of the need for further surgery due to tumour infiltration of the surgical margins. The history and clinical images are presented and we discuss the difficulties of cancer management at a rural district hospital.

Current surgical training is still highly dependent on expensive operating room (OR) experience. Although there have been many attempts to transfer more training to the skills laboratory, little research is focused on which technical behaviors can lead to the highest profit when they are trained outside the OR. The Pareto principle states that in any population that contributes to a common effect, a few account for the bulk of the effect. This principle has been widely used in business management to increase company profits. This study uses the Pareto principle for establishing content criteria for more efficient surgical training. A retrospective study was conducted to assess verbal guidance provided by 9 supervising surgeons to 12 trainees performing 64 laparoscopic cholecystectomies in the OR. The verbal corrections were documented, tallied, and clustered according to the aimed change in novice behavior. The corrections were rank ordered, and a cumulative distribution curve was used to calculate which corrections accounted for 80% of the total number of verbal corrections. In total, 253 different verbal corrections were uttered 1587 times and were categorized into 40 different clusters of aimed changes in novice behaviors. The 35 highest-ranking verbal corrections (14%) and the 11 highest-ranking clusters (28%) accounted for 80% of the total number of given verbal corrections. Following the Pareto principle, we were able to identify the aspects of trainee behavior that account for most corrections given by supervisors during a laparoscopic cholecystectomy on humans. This strategy can be used for the development of new training programs to prepare the trainee in advance for the challenges encountered in the clinical setting in an OR.

Fisher, J C; Powers, W E; Tuerk, D B; Edgerton, M T

1975-03-01

A plastic surgical teaching service has been organized at a women's correctional institution to provide a previously unrecognized medical need and to serve a valuable educational function for our residents in training. A total of 177 surgical candidates demonstrating a wide range of reconstructive problems including tattoos, scars, keloids, neoplasms of the skin and hands, deformities of the face and breasts, and numerous disabilities of the hands were identified among 241 inmates requesting examination. Thus far, 116 operative procedures have been performed on 101 patients. Patient acceptance has been high, and the support of prison authorities has been enthusiastic. Persistent efforts to convince legislators of the wisdom of supporting this program financially have only been partially successful and will require further accumulation of sociologic data bearing on the rehabilitative potential of the detained patient with a correctable deformity. Meanwhile, residents in training gain maturity as they provide a very "private" type of service for what has traditionally been considered a very "public" population of patients.

A new technique for correction of simple congenital earlobe clefts: diametric hinge flaps method.

PubMed

Qing, Yong; Cen, Ying; Xu, Xuewen; Chen, Junjie

2013-06-01

The earlobe plays an important part in the aesthetic appearance of the auricle. Congenital cleft earlobe may vary considerably in severity from a simple notching to extensive tissue deficiency. Most patients with cleft earlobe require surgical correction because of abnormal appearance. In this article, a new surgical technique for correcting congenital simple cleft earlobe using diametric hinge flaps is introduced. We retrospectively reviewed 4 patients diagnosed with congenital cleft earlobe between 2008 and 2010. All of them received this new surgical method. The patients were followed up from 3 to 6 months. All patients attained relatively full bodied earlobes with smooth contours, inconspicuous scars, and found their reconstructed earlobes to be aesthetically satisfactory. One patient experienced hypoesthesia in the area operated on, but recovered 3 months later. No other complications were noted. This simple method not only makes full use of the surrounding tissues to reconstruct full bodied earlobes but also avoids small notch formation caused by the linear scar contraction sometimes seen when using more traditional methods.

Autonomic nervous system function, child behavior, and maternal sensitivity in three-year-old children with surgically corrected transposition.

Harrison, Tondi M

2013-01-01

Explore relationships among autonomic nervous system (ANS) function, child behavior, and maternal sensitivity in three-year-old children with surgically corrected transposition of the great arteries (TGA) and in children healthy at birth. Children surviving complex congenital heart defects are at risk for behavior problems. ANS function is associated with behavior and with maternal sensitivity. Child ANS function (heart rate variability) and maternal sensitivity (Parent-Child Early Relational Assessment) were measured during a challenging task. Mother completed the Child Behavior Checklist. Data were analyzed descriptively and graphically. Children with TGA had less responsive autonomic function and more behavior problems than healthy children. Autonomic function improved with more maternal sensitivity. Alterations in ANS function may continue years after surgical correction in children with TGA, potentially impacting behavioral regulation. Maternal sensitivity may be associated with ANS function in this population. Continued research on relationships among ANS function, child behavior, and maternal sensitivity is warranted.

Plication procedures—excisional and incisional corporoplasty and imbrication for Peyronie’s disease

PubMed Central

Chen, Roger; McCraw, Casey

2016-01-01

Plication procedures for the correction of Peyronie’s disease (PD) curvature are management options for PD patients. There are basically three types of procedures: excisional corporoplasty, incisional corporoplasty, and plication-only. This review is a compilation of English literature, peer-reviewed, published articles addressing these types of operations for Peyronie’s curvature correction, not congenital curvature. According to the urology literature, this surgical type was initially used for correction of curvature associated with hypospadias repair or congenital penile curvature. The procedures also, for the most part, historically became an alternative for plaque excision and graft repair, because of the difficulty with such repairs and the often-resultant erectile dysfunction (ED). A brief section traces some of the origins of these various repairs, followed by a brief section on the selection criteria for these types of surgery for the patient with PD penile curvature. We also review the significant articles in which the three types were presented with modifications. Finally, several articles that compare the various surgical repairs are summarized in the order that they appear in the literature. These types of surgery have become a mainstay for the surgical correction of penile curvature due to PD. PMID:27298779

Management of High-Grade Penile Curvature Associated With Hypospadias in Children

PubMed Central

Moscardi, Paulo R. M.; Gosalbez, Rafael; Castellan, Miguel Alfedo

2017-01-01

Penile curvature is a frequent feature associated with hypospadias with also a great variability of severity among each patient. While the low-grade curvature (<30°) can be relatively easily corrected by simple techniques like penile degloving and dorsal plication, severe cases often demand more complex maneuvers to manage it. A great number of surgical techniques have been developed to adequately correct curvatures greater than 30°; however, each one of them should be individualized to different patients and local conditions encountered. In this article, we will review the evaluation of the pediatric patient with penile curvature associated with hypospadias with a special attention to high-grade cases, their management, indications for surgical treatment, and several surgical options for their definitive treatment.

The authors' primary objective was to test the hypothesis that Cerebral State Index (CSI)-guided control of anesthetic depth might reduce the consumption of anesthetics and shorten the duration of ICU and hospital stays after surgical correction of combined valve disorders. Single center, randomized trial. City Hospital Number 1 of Arkhangelsk, Russian Federation. Fifty adult patients with combined valve disorders requiring surgical correction. The patients were randomized into 2 groups. In the CSI group, anesthetic depth was monitored, and the rate of infusion of propofol was titrated to maintain the depth of anesthesia corresponding to a CSI of 40-60. In the control group, the depth of anesthesia was monitored clinically, and the dosage of propofol was administered according to the recommendations of the manufacturer. All patients received standard perioperative monitoring. Consumption of anesthetics and length of ICU and hospital stays were recorded. Preoperative patient characteristics did not differ significantly between the groups. In the CSI group, average intraoperative doses of midazolam and propofol were reduced by 41% and 19%, respectively (p<0.01). Maintenance of anesthesia guided by CSI shortened the time until fit for ICU discharge by 50% and reduced the lengths of ICU and postoperative hospital stays by 35% and 25%, respectively (p< 0.05). Monitoring of anesthetic depth reduces the requirements for midazolam and propofol, resulting in a faster recovery and a shorter postoperative ICU and hospital stay after surgical correction of combined valve disorders.

Surgical limb lengthening is undertaken to correct pathological short stature. Among the possible complications related to this procedure, painful and retractile scars are a cause for both functional and cosmetic concern. Our team has already shown the efficacy of autologous fat grafting in the treatment of scars with varying aetiology, so we decided to apply this technique to scars related to surgical correction of dwarfism. A prospective study was conducted to evaluate the efficacy of autologous fat grafting in the treatment of post-surgical scars in patients with short-limb dwarfism using durometer measurements and a modified patient and observer scar assessment scale (POSAS), to which was added a parameter to evaluate movement impairment. Between January 2009 and September 2012, 36 children (28 female and 8 male) who presented retractile and painful post-surgical scars came to our unit and were treated with autologous fat grafting. Preoperative and postoperative mean durometer measurements were analysed using the analysis of variance (ANOVA) test and POSAS parameters were studied using the Wilcoxon rank sum test. There was a statistically significant reduction in all durometer measurements (p-value <0.05) and in all but one of the POSAS parameters (p-value <0.05) following treatment with autologous fat grafting. Surgical procedures to camouflage scars on lower limbs are not often used as a first approach and non-surgical treatments often lead to unsatisfactory results. In contrast, our autologous fat grafting technique in the treatment of post-surgical scars has been shown to be a valuable option in patients with short-limb dwarfism. There was a reduction of skin hardness and a clinical improvement of all POSAS parameters in all patients treated. Moreover, the newly introduced POSAS parameter appears to be reliable and we recommend that it is included to give a more complete evaluation of patient perception. Copyright © 2014 Elsevier Ltd.

To investigate the advantage of performing cesarean section using the Misgav-Ladach method and to justify its use in everyday practice. In a prospective study we analyzed over a two year period (2000-01) cesarean sections carried out using the Misgav-Ladach method at our clinic. We compared both 550 cases of Misgav-Ladach (ML) and 100 cases of Pfannenstiel (PH) cesarean section. In the group that had undergone the Misgav-Ladach method we sutured the uterus in one layer and left the peritoneum non-sutured, and in the group who had undergone Pfennenstiel we sutured the uterus in two layers and also sutured the visceral and parietal peritoneum. In every case we analyzed: maternal age, gestational age, duration of operation, consumption of suture material, duration of hospitalization, and surgical complications. Incidence of postoperative febrile morbidity was 5.45%, in the Misgav-Ladach group compared with 13.2% in the Pfannenstiel group (p < 0.05). Local infection of the wound in the Misgav-Ladach group was found in 4.54% and in the Pfannenstiel group in 9% (p < 0.05). Mean time of extraction of the newborn in the Misgav-Ladach group was 1.25 minutes, and in the Pfannenstiel group 4.10 minutes (P < 0.05). Mean duration of operation in the Misgav-Ladach group was 10.98 min, and in the Pfannenstiel group 25 min (p < 0.05). Mean duration of hospitalization in the Misgav-Ladach group was 4.75 days, and in the Pfannenstiel group 6.32 days (p > 0.05). Mean consumption of suture material in the group Misgav-Ladach was 3.10 sutures per operation, and in the Pfannenstiel group was 9.5 sutures. Our study shows that the Misgav-Ladach method of cesarean section enables fast recovery and shorter hospitalization, and reduces the length of the operation, the incidence of surgical complication and the consumption of surgical materials.

Tethered cord release: a long-term study in 114 patients.

All children born with a myelomeningocele at the authors' institution undergo aggressive treatment to maintain or improve functional outcome. Consequently, when any neurological, orthopedic, and/or urological changes are noted, a search for the cause is initiated. The most common cause of decline in a child born with a myelomeningocele is shunt malfunction. The second most common cause is tethering of the distal spinal cord at the site of the original back closure. In this report, the authors review the indicators of symptomatic spinal cord tethering and discuss the surgical interventions and outcomes in the children with myelomeningocele who underwent treatment at Children's Memorial Hospital from 1975 to 2008. Among the 502 children who underwent original closure at Children's Memorial Hospital, a symptomatic tethered spinal cord developed in 114 (23%). Eighty-one patients (71%) have undergone 1 untethering procedure, and 33 patients (29%) have undergone multiple untetherings, for a total of 163 total surgeries. The indicators of symptomatic spinal cord tethering include scoliosis, decline in lower-extremity (LE) motor strength, LE contractures, LE spasticity, gait change, urinary changes, and pain. Pain has shown the best response to surgical untethering, with 100% of children experiencing postoperative improvement. The results of long-term follow-up (average 12 years, range 1 month-23.3 years) in this cohort demonstrated scoliosis progression after surgical untethering in 52% of patients, with 28% requiring spinal fusion. On the 3-month postoperative manual muscle test, 70% of patients showed improved LE muscle strength compared to preoperatively. Gait was also similarly improved after untethering as evaluated by an orthopedic surgeon. Spasticity improved in two-thirds of the cohort, and as expected, LE contractures were stable (78%) postoperatively, as assessed by orthopedic and rehabilitation medicine specialists. Urologically, 64% of patients showed improvements on postoperative bladder evaluation. Although this is a clinical outcome study with no control group, the authors' experience has been that tethered cord release is beneficial in maintaining neurological, urological, and orthopedic functioning in children born with a myelomeningocele.

UPDATE The print version of this article has errors that have been corrected in the online version of this article. In the Materials and Methods section, the sentence that reads as "During the study period, our institution offered preoperative autologous blood donation to all patients who were scheduling for total joint arthroplasty with a hemoglobin level of no less than 11 mg/dL or a hematocrit level of at least 33%." in the print version now reads as "During the study period, our institution offered preoperative autologous blood donation to all patients who were scheduling for total joint arthroplasty with a hemoglobin level of no less than 11 g/dL or a hematocrit level of at least 33%." in the online version. In Table III, the footnote that reads as "The values are given as the estimate and the standard error in milligrams per deciliter." in the print version now reads as "The values are given as the estimate and the standard error in grams per deciliter." in the online version. Despite advances in surgical and anesthetic techniques, lower-extremity total joint arthroplasty is associated with considerable perioperative blood loss. As predictors of perioperative blood loss and allogenic blood transfusion have not yet been well defined, the purpose of this study was to identify clinical predictors for perioperative blood loss and allogenic blood transfusion in patients undergoing total joint arthroplasty. From 2000 to 2008, all patients undergoing unilateral primary total hip or knee arthroplasty who met the inclusion criteria were enrolled in the study. Perioperative blood loss was calculated with use of a previously validated formula. The predictors of perioperative blood loss and allogenic blood transfusion were identified in a multivariate analysis. Eleven thousand three hundred and seventy-three patients who underwent total joint arthroplasty, including 4769 patients who underwent total knee arthroplasty and 6604 patients who underwent total hip arthroplasty, were evaluated. Multivariate analysis indicated that an increase in blood loss was associated with being male (263.59 mL in male patients who had undergone total hip arthroplasty and 233.60 mL in male patients who had undergone total knee arthroplasty), a Charlson Comorbidity Index of >3 (293.99 mL in patients who had undergone total hip arthroplasty and 167.96 mL in patients who had undergone total knee arthroplasty), and preoperative autologous blood donation (593.51 mL in patients who had undergone total hip arthroplasty and 592.30 mL in patients who had undergone total knee arthroplasty). In patients who underwent total hip arthroplasty, regional anesthesia compared with general anesthesia reduced the amount of blood loss. The risk of allogenic blood transfusion increased with the amount of blood loss in the patients who underwent total hip arthroplasty (odds ratio, 1.43 [95% confidence interval, 1.40 to 1.46]) and the patients who underwent total knee arthroplasty (odds ratio, 1.47 [95% confidence interval, 1.42 to 1.51]), but the risk of blood transfusion increased with the Charlson Comorbidity Index only in patients who underwent total knee arthroplasty (odds ratio, 3.2 [95% confidence interval, 1.99 to 5.15]). The risk of allogenic blood transfusion decreased with preoperative autologous blood donation in patients who underwent total hip arthroplasty (odds ratio, 0.01 [95% confidence interval, 0.01 to 0.02]) and patients who underwent total knee arthroplasty (odds ratio, 0.02 [95% confidence interval, 0.01 to 0.03]). This study identified some clinical predictors for blood loss in patients undergoing total joint arthroplasty that we believe can be used for implementing more effective blood conservation strategies.

Gynecomastia is defined as the benign enlargement of the male breast. Most studies on surgical treatment of gynecomastia show only small series and lack histopathology results. The aim of this study was to analyze the surgical approach in the treatment of gynecomastia and the related outcome over a 10-year period. All patients undergoing surgical gynecomastia corrections in our department between 1996 and 2006 were included for retrospective evaluation. The data were analyzed for etiology, stage of gynecomastia, surgical technique, complications, risk factors, and histological results. A total of 100 patients with 160 operations were included. Techniques included subcutaneous mastectomy alone or with additional hand-assisted liposuction, isolated liposuction, and formal breast reduction. Atypical histological findings were found in 3% of the patients (spindle-cell hemangioendothelioma, papilloma). The surgical revision rate among all patients was 7%. Body mass index and a weight of the resected specimen higher than 40 g were identified as significant risk factors for complications (p < 0.05). The treatment of gynecomastia requires an individualized approach. Caution must be taken in performing large resections, which are associated with increased complication rates. Histological tissue analysis should be routinely performed in all true gynecomastia corrections, because histological results may reveal atypical cellular pathology.

A retrospective study. The aim of this study was to investigate the correlation between pelvic incidence (PI) and lumbar lordosis (LL) mismatch and knee flexion during standing in patients with lumbar degenerative diseases and to examine the effects of surgical correction of the PI-LL mismatch on knee flexion. Only several studies focused on knee flexion as a compensatory mechanism of the PI-LL mismatch. Little information is currently available on the effects of lumbar correction on knee flexion in patients with the PI-LL mismatch. A group of patients with lumbar degenerative diseases were divided into PI-LL match group (PI-LL ≤ 10°) and PI-LL mismatch group (PI-LL > 10°). A series of radiographic parameters and knee flexion angle (KFA) were compared between the two groups. The PI-LL mismatch group was further subdivided into operative and nonoperative group. The changes in KFA with PI-LL were examined. The PI-LL mismatch group exhibited significantly greater sagittal vertical axis (SVA), pelvic tilt (PT) and KFA, and smaller LL, thoracic kyphosis (TK), and sacral slope than the PI-LL match group. PI-LL, LL, PI, SVA, and PT were significantly correlated with KFA in the PI-LL mismatch group. From baseline to 6-month follow-up, all variables were significantly different in the operative group with the exception of PI, although there was no significant difference in any variable in the nonoperative group. The magnitude of surgical correction in the PI-LL mismatch was significantly correlated with the degree of spontaneous changes in KFA, PT, and TK. The PI-LL mismatch would contribute to compensatory knee flexion during standing in patients with lumbar degenerative disease. Surgical correction of the PI-LL mismatch could lead to a spontaneous improvement of compensatory knee flexion. The degree of improvement in knee flexion depends in part on the amount of correction in the PI-LL mismatch. 3.

Correction of gynecomastia in males is a frequently performed aesthetic procedure. Various surgical options involving the removal of excess skin, fat, or glandular tissue have been described. However, poor aesthetic outcomes, including a flat or depressed pectoral area, limit the success of these techniques. The authors sought to determine patient satisfaction with the results of upper chest augmentation by direct intrapectoral fat injection in conjunction with surgical correction of gynecomastia. In this prospective study, 26 patients underwent liposuction and glandular excision, glandular excision alone, or Benelli-type skin excision. All patients received intramuscular fat injections in predetermined zones of the pectoralis major (PM). The mean volume of fat injected was 160 mL (range, 80-220 mL per breast) bilaterally. Patients were monitored for an average of 16 months (range, 8-24 months). Hematoma formation and consequent infraareolar depression was noted in 1 patient and was corrected by secondary lipografting. Mean patient satisfaction was rated as 8.4 on a scale of 1 (unsatisfactory) to 10 (highly satisfactory). Autologous intrapectoral fat injection performed simultaneously with gynecomastia correction can produce a masculine appearance. The long-term viability of fat cells injected into the PM needs to be determined. 4 Therapeutic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: One was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

Two children who had undergone a transappendicular urinary diversion (type Mitrofanoff) developed bladder rupture, one following abdominal trauma, 4 months after the operation and the other following traumatic self-catheterization at 4 years. The clinical history and standard radiological examinations (ultrasonography, cystography) confirmed the diagnosis of urinary peritonitis. Emergency surgical repair was possible in both cases with an uneventful postoperative course. This serious and rare complication requires emergency surgery and justifies rigorous selection of children suitable for this type of diversion giving preference to increased bladder neck resistance over bladder neck closure.

To describe intra- and post-operative complications, as well as the evolution of the surgical technique in first 4years of work of a novice retina surgeon, and evaluate minimal learning time required to reduce its complications, deciding which pathologies should still be referred to higher level hospitals, until further experience may be achieved. A study was conducted on patients that had undergone vitreoretinal surgery by a novice surgeon in Tarragona between 23rd October 2007 and 31st December 2011. The primary diagnosis, surgeon learning time, surgical technique, intra-operative and post-operative complications were recorded. A total of 247 surgeries were studied. The percentage of use of 20G and 23G calibres during the time, marks a change towards trans-conjunctival surgery from the ninth trimester (98 surgeries). Surgical complications decreased towards twelfth trimester (130 surgeries) with an increase in the previous months. The shift towards 23G technique around 100 surgeries is interpreted as greater comfort and safety by the surgeon. Increased surgical complications during the following months until its decline around 130 surgeries can be interpreted as an 'overconfidence'. It is arguable that the learning curve is slower than what the surgeon believes. An individual analysis of the complications and surgical outcomes is recommended to ascertain the status of the learning curve. Copyright © 2016 Sociedad Española de Oftalmología.

Presurgical sensorimotor mapping with functional MR imaging is gaining acceptance in clinical practice; however, to our knowledge, its therapeutic efficacy has not been assessed in a sizable group of patients. Our goal was to identify how preoperative sensorimotor functional studies were used to guide the treatment of neuro-oncologic and epilepsy surgery patients. We retrospectively reviewed the medical records of 46 patients who had undergone preoperative sensorimotor functional MR imaging to document how often and in what ways the imaging studies had influenced their management. Clinical management decisions were grouped into three categories: for assessing the feasibility of surgical resection, for surgical planning, and for selecting patients for invasive functional mapping procedures. Functional MR imaging studies successfully identified the functional central sulcus ipsilateral to the abnormality in 32 of the 46 patients, and these 32 patients are the focus of this report. In epilepsy surgery candidates, the functional MR imaging results were used to determine in part the feasibility of a proposed surgical resection in 70% of patients, to aid in surgical planning in 43%, and to select patients for invasive surgical functional mapping in 52%. In tumor patients, the functional MR imaging results were used to determine in part the feasibility of surgical resection in 55%, to aid in surgical planning in 22%, and to select patients for invasive surgical functional mapping in 78%. Overall, functional MR imaging studies were used in one or more of the three clinical decision-making categories in 89% of tumor patients and 91% of epilepsy surgery patients. Preoperative functional MR imaging is useful to clinicians at three key stages in the preoperative clinical management paradigm of a substantial percentage of patients who are being considered for resective tumor or epilepsy surgery.

To evaluate and compare outcomes of Descemet's stripping endothelial keratoplasty (DSEK) with non-DSEK (nDSEK) in pseudophakic corneal oedema (PCE). The study was a prospective, non-consecutive, comparative, interventional case series. Twenty-six patients with PCE were randomised into two groups. Group 1 comprised of those cases that had undergone conventional DSEK, and group 2 consisted of those that had nDSEK for PCE between 2010 and 2012. The data on demographics and clinical characteristics were collected from all patients. Any intraoperative and early and late postoperative complications were also noted. The primary outcome measure was postoperative functional success. Graft survival and complications were analysed as secondary outcomes. The median best-corrected visual acuities at 6 months postoperatively in groups 1 and 2 were 0.18 (IQR 0.10-0.30) and 0.44 (IQR 0.18-0.51), respectively (p=0.11). Corneal oedema cleared in all patients. During the early postoperative period, a patient in group 2 had lenticule detachment managed by rebubbling. nDSEK has outcomes similar to DSEK in PCE with advantages of decreased surgical time and avoidance of inadvertent pull on the posterior stromal fibres that may occur during Descemet's stripping.

Advancements in the understanding of adult spinal deformity have led to a greater awareness of the role of the pelvis in maintaining sagittal balance and alignment. Pelvic incidence has emerged as a key radiographic measure and should closely match lumbar lordosis. As proper measurement of the pelvic incidence requires accurate identification of the S-1 endplate, lumbosacral transitional anatomy may lead to errors. The purpose of this study is to demonstrate how lumbosacral transitional anatomy may lead to errors in the measurement of pelvic parameters. The current case highlights one of the potential complications that can be avoided with awareness. The authors report the case of a 61-year-old man who had undergone prior lumbar surgeries and then presented with symptomatic lumbar stenosis and sagittal malalignment. Radiographs showed a lumbarized S-1. Prior numbering of the segments in previous surgical and radiology reports led to a pelvic incidence calculation of 61°. Corrected numbering of the segments using the lumbarized S-1 endplate led to a pelvic incidence calculation of 48°. Without recognition of the lumbosacral anatomy, overcorrection of the lumbar lordosis might have led to negative sagittal balance and the propensity to develop proximal junction failure. This case illustrates that improper identification of lumbosacral transitional anatomy may lead to errors that could affect clinical outcome. Awareness of this potential error may help improve patient outcomes.

To review the outcome of Z-plasty of the flexor hallucis longus (FHL) tendon at the tarsal tunnel for checkrein deformity in 8 patients. Records of 6 males and 2 females aged 14 to 67 (mean, 39.5) years who underwent Z-plasty (lengthening) of the FHL tendon at the tarsal tunnel for checkrein deformity in the first and second toes by a single surgeon were reviewed. All patients had undergone 3 months of conservative treatment. The mean time from injury to surgical treatment was 8.4 (range, 5-12) months. All patients had associated injuries including distal tibiofibular fracture (n=6), distal fibular fracture (n=1), and crush injury aroundthe ankle (n=1); they were treated with intramedullary nailing (n=6), long leg splinting (n=1), and short leg splinting (n=1). After a mean follow-up of 3.4 (range, 1-7) years, the FHL tendon was lengthened by a mean of 1.7 (range, 1.6-1.8) cm, and the mean American Orthopedic Foot and Ankle Society hallux score increased from 59 (range, 52-67) to 89 (range, 80-90). No patient had recurrence, nerve injury, or tarsal tunnel syndrome, although one patient had sensory disturbance of the posterior tibial nerve in the forefoot, which resolved spontaneously at week 2. Z-plasty of the FHL tendon at the tarsal tunnel is a viable option for correction of checkrein deformity.

Transverse mucoperiosteal flap inset by rotation for cleft palate repair: technique and outcomes.

PubMed

Black, Jonathan S; Gampper, Thomas J

2014-01-01

Cleft palate is a relatively common deformity with various techniques described for its repair. Most techniques address the hard palate portion of the cleft with bilateral mucoperiosteal flaps transposed to the midline. This results in superimposed, linear closure layers directly over the cleft and may predispose the repair to oronasal fistula formation. This report details an alternative technique of flap rotation with an outcome analysis. A retrospective chart analysis was performed of all patients having undergone primary palatoplasty for cleft palate. Demographics and cleft Veau type were recorded. Postoperative speech outcomes were assessed by standardized speech evaluation performed by 2 speech language pathologists. The presence and location of oronasal fistulae was assessed and recorded by the surgeon and speech language pathologists in follow-up evaluations. The study revealed an overall incidence of velopharyngeal insufficiency of 5.7% using this surgical technique. It also revealed a fistula rate of 8.6%. Secondary surgery has been successful in those patients in which it was indicated. Eleven (31%) patients were diagnosed with Robin sequence. This technique demonstrates excellent early outcomes in a difficult subset of cleft patients including a high proportion of those with Pierre Robin sequence. The technique addresses the inherent disadvantages to a linear closure over the bony cleft. The variability in its design provides the surgeon another option for correction of this deformity.

The implications of a diagnosis and consequent surgical treatment for breast cancer may be different for young women compared to older women. This study investigated the information requirements of young women to support their treatment decision making at diagnosis.
. A purposeful sample of 20 women diagnosed with breast cancer aged 40 years or younger who had undergone surgery and had participated in a large cohort study in the United Kingdom.
. Audio recordings of semistructured interviews were used to reveal information received at the time of surgical treatment.
. Themes identified were types of breast cancer, surgical treatments, nonsurgical treatments, fertility, and surgery and after surgery. Participants felt that information required throughout treatment was influenced by individual life circumstances, such as children or plans for children, relationships, and career intentions. Participants felt information was lacking on the effects of treatment on body image, reconstructive surgery, and genetic predisposition to breast cancer.
. Knowledge of the information requirements of young women diagnosed with breast cancer allows nursing staff to provide tailored support at times identified as most useful.

Current Trends in the Management of Abdominal Aortic Aneurysms

1987-01-01

The treatment of abdominal aortic aneurysm has undergone dramatic changes over the last three decades. More sophisticated diagnostic techniques have allowed early elective repair to be carried out. Improvement has resulted in both morbidity and mortality rates. Investigations such as ultrasound, computerized tomographic scanning and arteriography allow easy confirmation of the diagnosis of aortic aneurysms and permit a better assessment of the extent prior to surgical intervention. Improvement in the pre-operative management, particularly in relation to cardiac, renal, and pulmonary disease, has led to greatly improved results. The most important change in surgical technique has been repair of the aneurysm rather than resection. Combined with better post-operative intensive care units, this development has contributed to the improved morbidity and mortality rates. Although the complication rate of elective repair is low, the major cause of death remains myocardial infarction. As a result of all these improvements, indication for repair of abdominal aortic aneurysms has been extended to patients over the age of 80. Following surgical repair, most patients can be expected to return to normal lifestyles and lifespans. ImagesFigure 2Figure 3Figure 4 PMID:21263973

The effect of interleukin-2 on canine peripheral nerve sheath tumours after marginal surgical excision: a double-blind randomized study

PubMed Central

2013-01-01

Background The objective of this study was to evaluate the effect on outcomes of intraoperative recombinant human interleukin-2 injection after surgical resection of peripheral nerve sheath tumours. In this double-blind trial, 40 patients due to undergo surgical excision (<5 mm margins) of presumed peripheral nerve sheath tumours were randomized to receive intraoperative injection of interleukin-2 or placebo into the wound bed. Results There were no significant differences in any variable investigated or in median survival between the two groups. The median recurrence free interval was 874 days (range 48–2141 days), The recurrence-free interval and overall survival time were significantly longer in dogs that undergone the primary surgery by a specialist-certified surgeon compared to a referring veterinarian regardless of whether additional adjunct therapy was given. Conclusion Overall, marginal excision of peripheral nerve sheath tumours in dogs resulted in a long survival time, but adjuvant treatment with recombinant human interleukin-2 (rhIL-2) did not provide a survival advantage.

2013-01-01

Nutritional support of surgical and critically ill patients has undergone significant advances since 1936 when Studley demonstrated a direct relationship between pre-operative weight loss and operative mortality. The advent of total parenteral nutrition followed by the extraordinary progress in parenteral and enteral feedings, in addition to the increased knowledge of cellular biology and biochemistry, have allowed clinicians to treat malnutrition and improve surgical patient’s outcomes. We reviewed the literature for the current status of perioperative nutrition comparing parenteral nutrition with enteral nutrition. In a surgical patient with established malnutrition, nutritional support should begin at least 7–10 days prior to surgery. Those patients in whom eating is not anticipated beyond the first five days following surgery should receive the benefits of early enteral or parenteral feeding depending on whether the gut can be used. Compared to parenteral nutrition, enteral nutrition is associated with fewer complications, a decrease in the length of hospital stay, and a favorable cost-benefit analysis. In addition, many patients may benefit from newer enteral formulations such as Immunonutrition as well as disease-specific formulations. PMID:23429491

Cancellations have an important role in the effectiveness of the surgical schedule. Analyze the evolution of the cancellations during the years 1994-1997, after institution of several corrective measures. We started in 1994 together with the Quality Unit of the Hospital, a program to reduce surgical cancellations. It consisted in improvement of parents information, surgical schedule centralization, and increasing the awareness of the importance of constant improvement. Cancellations have been divided in: inevitables and inevitables, and analyzed for the entire Service and for each speciality. A significant reduction of cancellations have been obtain (from 12.38% in 1992 to 3.35% in 1997). The inevitable causes (no presentation, inadequate preparation and lack of time in the surgical room) have shown the most improvement. Although the inevitable causes (intercurrent disease) were also significantly improved, after obtaining prior information of the health of the child, by telephone call or parents advise. ENT is the speciality with greatest improvement by significant reduction of the non presentation and intercurrent disease. After corrective measures conjointly with a realistic surgical schedule, prior telephone call and improvement quality concept, have permitted a significant reduction of cancellations.

Appearance-change instruction effects on eyewitness lineup identification accuracy are not moderated by amount of appearance change.

2013-12-01

Instructing witnesses that a criminal may have changed appearance prior to showing them a lineup has been shown to increase false identifications without increasing correct identifications (S. D. Charman & G. L. Wells, 2007, Is the appearance-change instruction a good idea? Law and Human Behavior, Vol. 31, pp. 3-22). However, the generalizability of the effects of this appearance-change instruction (ACI) is unknown, and there are reasons to believe that the instruction's effects may be moderated by the amount of appearance change the criminal has actually undergone. The current study tested this hypothesis. Undergraduate students (N = 315) were exposed to a series of target faces and lineups, some of which contained the target and some of which did not, and made identification decisions. Half of the participants received a standard ACI prior to each lineup; the other half did not. The targets varied with respect to the amount to which their appearance had changed. Results indicated that the ACI inflated false identifications without inflating correct identifications, and that these effects did not depend on the amount of appearance change the target had undergone. Current recommendations to administer the ACI seem to be unfounded and may be harmful to the reliability of identification evidence. (c) 2013 APA, all rights reserved

A grossly displaced segmental zygomatic arch fracture with marked ventro-lateral deviation of the left globe was diagnosed in a 3-month-old male German Shepherd dog following a bite injury. The fracture was approached via a modified lateral orbitotomy and a fragment of the lacrimal bone removed. The rostral portion of the fracture was stabilized with a 5-hole 2.0 dynamic compression plate bone plate. The surgical correction achieved sufficient skeletal fixation for proper anatomical reduction of the globe and excellent cosmetic and functional outcomes.

Orthognathic surgery has become an acceptable treatment plan for patients with various maxillofacial deformities. The rehabilitation of severe class III adult patients requires a complex interdisciplinary orthodontic and orthognathic approach. This presentation aims to show a case of combination of camouflage and bilateral sagittal split osteotomy (BSSO).Camouflage in maxillary arch was accepted after analysing visual treatment objective (VTO) and pleasing soft tissue compensation which gave us the clue to go ahead for surgical correction of excess mandibular length to achieve best aesthetic outcome while maintaining nature's compensation in upper arch.

Prosthetic Correction of Postenucleation Socket Syndrome: A Case Report.

PubMed

Kamble, Vikas B

2014-12-01

Postenucleation socket syndrome is a frequent late complication of enucleation of eye globe. Several pathophysiological mechanisms have been proposed to account for the symptoms of postenucleation socket syndrome, which include lost orbital volume, superior sulcus deformity, upper eyelid ptosis, lower eyelid laxity, and backward tilt of the prosthesis. The goal of postenucleation socket syndrome treatment is to achieve the best possible functional and esthetic result. The treatment can be either conservative or surgical. For the patient interested in a non-surgical correction, the conservative treatment is simple and non invasive and can be done with prosthesis modification for good positioning, comfort, and mobility. This paper describes prosthetic correction of a patient with postenucleation socket syndrome by modified ocular prosthesis.

Correction factor for ablation algorithms used in corneal refractive surgery with gaussian-profile beams

We provide a correction factor to be added in ablation algorithms when a Gaussian beam is used in photorefractive laser surgery. This factor, which quantifies the effect of pulse overlapping, depends on beam radius and spot size. We also deduce the expected post-surgical corneal radius and asphericity when considering this factor. Data on 141 eyes operated on LASIK (laser in situ keratomileusis) with a Gaussian profile show that the discrepancy between experimental and expected data on corneal power is significantly lower when using the correction factor. For an effective improvement of post-surgical visual quality, this factor should be applied in ablation algorithms that do not consider the effects of pulse overlapping with a Gaussian beam.

This article aimed to present a case of 22 year-old Thai female with cleft lip and palate who had malocclusion developed from dental problems, skeletal disharmony and unrepaired alveolar cleft. The treatment was orthodontic combined with one-stage surgical correction which corrected skeletal discrepancy and alveolar cleft in single operation. After treatment, the patient had improved in facial esthetics, attaining good occlusal function and continuous maxillary dental arch. This procedure can reduce morbidity, preclude a second hospitalization and the cost of two-stage surgical correction. However this is only an alternative treatment for adult cleft patients who need late alveolar bone graft and orthognathic surgery.

To describe the surgical technique of complex distal femoral deformity correction with the aid of stereolithography apparatus (SLA) biomodels, stabilized with locking plate fixation. Full-size replica epoxy bone biomodels of the affected femurs (4 dogs/ 5 limbs) were used as templates for surgical planning. A rehearsal procedure was performed on the biomodels aided by a guide wire technique and stabilized with locking plate fixation. Surgery performed in all dogs was guided by the rehearsal procedure. All pre-contoured implants were subsequently used in the definitive surgical procedure with minimal modification. All dogs had markedly improved, with near normal functional outcomes; all but one had a mild persistent lameness at the final in-hospital follow-up examination (mean: 54.4 weeks; range: 24-113 weeks after surgery). All femurs healed without complications (mean: 34 weeks, median: 12 weeks; range: 8-12 weeks for closing osteotomies, and 26-113 weeks for opening wedge osteotomies). Long-term follow-up examination (mean: 28.6 months; range: 5-42 months) revealed all but one owner to be highly satisfied with the outcome. Complications were observed in two dogs: prolonged tibiotarsal joint decreased flexion that resolved with physical therapy. In one of these dogs, iatrogenic transection of the long digital extensor tendon was repaired, and the other had a peroneal nerve neurapraxia. Stereolithography apparatus biomodels and rehearsal surgery simplified the definitive surgical corrections of complex femoral malunions and resulted in good functional outcomes.

Hip dysplasia, pelvic obliquity, and scoliosis in cerebral palsy: a qualitative analysis using 3D CT reconstruction

Russ, Mark D.; Abel, Mark F.

1998-06-01

Five patients with cerebral palsy, hip dysplasia, pelvic obliquity, and scoliosis were evaluated retrospectively using three dimensional computed tomography (3DCT) scans of the proximal femur, pelvis, and lumbar spine to qualitatively evaluate their individual deformities by measuring a number of anatomical landmarks. Three dimensional reconstructions of the data were visualized, analyzed, and then manipulated interactively to perform simulated osteotomies of the proximal femur and pelvis to achieve surgical correction of the hip dysplasia. Severe deformity can occur in spastic cerebral palsy, with serious consequences for the quality of life of the affected individuals and their families. Controversy exists regarding the type, timing and efficacy of surgical intervention for correction of hip dysplasia in this population. Other authors have suggested 3DCT studies are required to accurately analyze acetabular deficiency, and that this data allows for more accurate planning of reconstructive surgery. It is suggested here that interactive manipulation of the data to simulate the proposed surgery is a clinically useful extension of the analysis process and should also be considered as an essential part of the pre-operative planning to assure that the appropriate procedure is chosen. The surgical simulation may reduce operative time and improve surgical correction of the deformity.

Keratoconus in Civil Aviation Pilots in a Report of Six Cases.

Keratoconus is a progressive noninflammatory ectatic corneal dystrophy, characterized by corneal thinning and increased curvature with central or paracentral tapered protrusion. Such changes in corneal morphology induce irregular astigmatism and myopia, resulting in visual acuity impairment. This report assesses cases in which keratoconus is not an absolute disabling condition for civil aviation pilots. Six cases of keratoconus in active pilots are presented. This report includes cases which were treated with crosslinking therapy and even corneal transplantation. In such cases, the civil aviation medical authority considered four aspects in the medical assessment: best corrected visual acuity, condition stability, risk of sudden incapacitation, and pilot category. Six civil pilots with ages between 19 and 45 yr of age presented with keratoconus in different stages. Using the Snellen scale, best corrected visual acuity (BCVA) was measured in 12 eyes, all of them having equal or better than 20/30 (20/20, N = 9; 20/25, N = 2; 20/30, N = 1). All of them are currently fit for aviation activity and have been given an aviation medical certificate with limitation of use of corrective lenses by the Brazilian Civil Aviation Authority (ANAC in Portuguese). Among these cases, there is a pilot who had undergone treatment with crosslinking therapy and another that had undergone corneal transplantation. These cases demonstrate that keratoconus is not always a disabling condition for civil aviation pilots. Nevertheless, it has to be analyzed on a case-by-case basis.Rebello A, Rodrigues B, Pereira M.

Evaluation of new Deflux administration techniques: intraureteric HIT and Double HIT for the endoscopic correction of vesicoureteral reflux.

PubMed

Kirsch, Andrew J; Arlen, Angela M

2014-09-01

Vesicoureteral reflux (VUR) is one of the most common urologic diagnoses affecting children, and optimal treatment requires an individualized approach that considers potential risks. Management options include observation with or without continuous antibiotic prophylaxis and surgical correction via endoscopic, open or laparoscopic/robotic approaches. Endoscopic correction of VUR is an outpatient procedure associated with decreased morbidity compared with ureteral reimplantation. The concept of ureteral hydrodistention and intraluminal submucosal injection (Hydrodistention Implantation Technique [HIT]) has led to improved success rates in eliminating VUR compared with the subureteral transurethral injection technique. Further modifications now include use of proximal and distal intraluminal injections (Double HIT) that result in coaptation of both the ureteral tunnel and orifice. Endoscopic injection of dextranomer/hyaluronic acid copolymer, via the HIT and Double HIT, has emerged as a highly successful, minimally invasive alternative to open surgical correction, with minimal associated morbidity.

We describe a new video-assisted operative technique for correction of pectus carinatum (PC) using a modified Nuss procedure. A new design of the steel bar was developed, so that it could be introduced and placed in a suitable position through very small skin incisions. Substantial modifications were introduced in the bar length and shape aimed at facilitating insertion and subsequent removal when required. All the surgical manoeuvres took place under direct vision using a 30° thoracoscope. Single unilateral fixation of the bar in a subpectoral pocket provided satisfactory stabilisation without the need for lateral stabilisers. Adequate correction of the deformity was achieved with minor postoperative scars. Our results support the view that minimally invasive surgical repair should be preferred over open surgery for correction of pectus carinatum in young adults and children.

2012-05-01

Scoliosis is defined as a spinal pathology characterized as a three-dimensional deformity of the spine combined with vertebral rotation. Treatment for severe scoliosis is achieved when the scoliotic spine is surgically corrected and fixed using implanted rods and screws. Several studies performed biomechanical modeling and corrective forces measurements of scoliosis correction. These studies were able to predict the clinical outcome and measured the corrective forces acting on screws, however, they were not able to measure the intraoperative three-dimensional geometry of the spinal rod. In effect, the results of biomechanical modeling might not be so realistic and the corrective forces during the surgical correction procedure were intra-operatively difficult to measure. Projective geometry has been shown to be successful in the reconstruction of a three-dimensional structure using a series of images obtained from different views. In this study, we propose a new method to measure the three-dimensional geometry of an implant rod using two cameras. The reconstruction method requires only a few parameters, the included angle θ between the two cameras, the actual length of the rod in mm, and the location of points for curve fitting. The implant rod utilized in spine surgery was used to evaluate the accuracy of the current method. The three-dimensional geometry of the rod was measured from the image obtained by a scanner and compared to the proposed method using two cameras. The mean error in the reconstruction measurements ranged from 0.32 to 0.45 mm. The method presented here demonstrated the possibility of intra-operatively measuring the three-dimensional geometry of spinal rod. The proposed method could be used in surgical procedures to better understand the biomechanics of scoliosis correction through real-time measurement of three-dimensional implant rod geometry in vivo.

Comprehensive Analysis of Mandibular Residual Asymmetry after Bilateral Sagittal Split Ramus Osteotomy Correction of Menton Point Deviation

2016-01-01

Purpose Facial asymmetry often persists even after mandibular deviation corrected by the bilateral sagittal split ramus osteotomy (BSSRO) operation, since the reference facial sagittal plane for the asymmetry analysis is usually set up before the mandibular menton (Me) point correction. Our aim is to develop a predictive and quantitative method to assess the true asymmetry of the mandible after a midline correction performed by a virtual BSSRO, and to verify its availability by evaluation of the post-surgical improvement. Patients and Methods A retrospective cohort study was conducted at the Hospital of Stomatology, Sun Yat-sen University (China) of patients with pure hemi-mandibular elongation (HE) from September 2010 through May 2014. Mandibular models were reconstructed from CBCT images of patients with pre-surgical orthodontic treatment. After mandibular de-rotation and midline alignment with virtual BSSRO, the elongation hemi-mandible was virtually mirrored along the facial sagittal plane. The residual asymmetry, defined as the superimposition and boolean operation of the mirrored elongation side on the normal side, was calculated, including the volumetric differences and the length of transversal and vertical asymmetry discrepancy. For more specific evaluation, both sides of the hemi-mandible were divided into the symphysis and parasymphysis (SP), mandibular body (MB), and mandibular angle (MA) regions. Other clinical variables include deviation of Me point, dental midline and molar relationship. The measurement of volumetric discrepancy between the two sides of post-surgical hemi-mandible were also calculated to verify the availability of virtual surgery. Paired t-tests were computed and the P value was set at .05. Results This study included 45 patients. The volume differences were 407.8±64.8 mm3, 2139.1±72.5 mm3, and 422.5±36.9 mm3; residual average transversal discrepancy, 1.9 mm, 1.0 mm, and 2.2 mm; average vertical discrepancy, 1.1 mm, 2.2 mm, and 2.2 mm (before virtual surgery). The post-surgical volumetric measurement showed no statistical differences between bilateral mandibular regions. Conclusions Mandibular asymmetry persists after Me point correction. A 3D quantification of mandibular residual asymmetry after Me point correction and mandible de-rotation with virtual BSSRO sets up a true reference mirror plane for comprehensive asymmetry assessment of bilateral mandibular structure, thereby providing an accurate guidance for orthognathic surgical planning.

Adolescent idiopathic scoliosis is a complex spinal pathology characterized as a three-dimensional spine deformity combined with vertebral rotation. Various surgical techniques for correction of severe scoliotic deformity have evolved and became more advanced in applying the corrective forces. The objective of this study was to investigate the relationship between corrective forces acting on deformed rods and degree of scoliosis correction. Implant rod geometries of six adolescent idiopathic scoliosis patients were measured before and after surgery. An elasto-plastic finite element model of the implant rod before surgery was reconstructed for each patient. An inverse method based on Finite Element Analysis was used to apply forces to the implant rod model such that it was deformed the same after surgery. Relationship between the magnitude of corrective forces and degree of correction expressed as change of Cobb angle was evaluated. The effects of screw configuration on the corrective forces were also investigated. Corrective forces acting on rods and degree of correction were not correlated. Increase in number of implant screws tended to decrease the magnitude of corrective forces but did not provide higher degree of correction. Although greater correction was achieved with higher screw density, the forces increased at some level. The biomechanics of scoliosis correction is not only dependent to the corrective forces acting on implant rods but also associated with various parameters such as screw placement configuration and spine stiffness. Considering the magnitude of forces, increasing screw density is not guaranteed as the safest surgical strategy. Copyright © 2012 Elsevier Ltd. All rights reserved.

Technical progress in the surgical operating room (OR) increases constantly, facilitating the development of intelligent OR systems functioning as "safety backup" in the background of surgery. Precondition is comprehensive data retrieval to identify imminent risky situations and inaugurate adequate security mechanisms. Radio-frequency-identification (RFID) technology may have the potential to meet these demands. We set up a pilot study investigating feasibility and appliance reliability of a stationary RFID system for real-time surgical sponge monitoring (passive tagged sponges, position monitoring: mayo-stand/abdominal situs/waste bucket) and OR team tracking (active transponders, position monitoring: right/left side of OR table). In vitro: 20/20 sponges (100%) were detected on the mayo-stand and within the OR-phantom, however, real-time detection accuracy declined to 7/20 (33%) when the tags were moved simultaneously. All retained sponges were detected correctly. In vivo (animal): 7-10/10 sterilized sponges (70%-100%) were detected correctly within the abdominal cavity. OR-team: detection accuracy within the OR (surveillance antenna) and on both sides of the OR table (sector antenna) was 100%. Mean detection time for position change (left to right side and contrariwise) was 30-60 s. No transponder failure was noted. This is the first combined RFID system that has been developed for stationary use in the surgical OR. Preclinical evaluation revealed a reliable sponge tracking and correct detection of retained textiles (passive RFID) but also demonstrated feasibility of comprehensive data acquisition of team motion (active RFID). However, detection accuracy needs to be further improved before implementation into the surgical OR. Copyright © 2012 Elsevier Inc. All rights reserved.

Iatrogenic flattening of lumbar lordosis in patients with adolescent idiopathic scoliosis (AIS) was a major downside of first generation instrumentation. Current instrumentation systems allow a three-dimensional scoliosis correction, but flattening of lumbar lordosis remains a significant problem which is associated with decreased health-related quality of life. This study sought to identify risk factors for loss of lumbar lordosis in patients who had surgical correction of AIS with the use of segmental instrumentation. Patients were included if they had surgical correction for AIS with segmental pedicle screw instrumentation Lenke type 1 or 2 and if they had a minimum follow-up of 24 months. Two groups were created, based on the average loss of lumbar lordosis. The two groups were then compared and multivariate analysis was performed to identify parameters that correlated to loss of lumbar lordosis. Four hundred and seventeen patients were analyzed for this study. The average loss of lumbar lordosis at 24 months follow-up was an increase of 10° lordosis for group 1 and a decrease of 15° for group 2. Risk factors for loss of lumbar lordosis included a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and the particular operating surgeon. The lowest instrumented vertebra or spinopelvic parameters were two of many parameters that did not seem to influence loss of lumbar lordosis. This study identified important risk factors for decrease of lumbar lordosis in patients who had surgical treatment for AIS with segmental pedicle screw instrumentation, including a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and factors attributable to a particular operating surgeon that were not quantified in this study.

1976-12-01

From Aug. 13, 1975, through May, 1976, nine patients underwent creation of a left ventricular "vent" for relief of severe left ventricular outflow tract obstruction. A Dacron fabric graft containing a heterograft valve was used to establish a conduit from the left ventricle to the abdominal aorta. There were five male and four female patients in this group; their ages ranged from 4 to 72 years. All had valvular, subvalvular, or supravalvular aortic stenosis, and all but two had undergone previous surgical procedures for relief of the stenosis. All patients survived the operation and none are receiving anticoagulant therapy. All are asymptomatic at present and follow-up is approaching one year. Postoperative cardiac catheterization studies revealed gradients across the aortic valve to be reduced by approximately 90% and mean ventricular systolic pressures by 45%. Although this concept is not new, it has not been used widely and we believe its effectiveness warrants further application.

A 31-year old female patient in the ninth week of pregnancy complained of chest pain and dyspnoea. The patient had experienced an episode of spontaneous pneumothorax on the left side at the age of 20 and had undergone chest tube drainage. Her medical history was unremarkable and she had no history of smoking. She had no family history of pulmonary disease. Thoracic radiography showed a pneumothorax on the right side. The patient underwent chest tube drainage in the thoracic space. When surgical intervention for continuous air leakage was unavoidable, we selected video-assisted thoracic surgery under local and epidural anaesthesia in consideration of her general condition. We conclude that awake surgical intervention is applicable in selected patients with pneumothorax in pregnancy and is particularly useful in those in whom general anaesthesia is best avoided.

A 21-year-old woman in the 16th week of pregnancy was admitted due to acute presentation of severe exertional dyspnea. She had undergone mitral valve replacement (MVR) with bioprosthetic valve for infective endocarditis 2 years ago. She developed congestive heart failure from mitral bioprosthetic valve stenosis due to early structural valve deterioration. She also had severe pulmonary hypertension and underwent a redo MVR using a mechanical valve prosthesis with good maternal outcome but fetal demise. This report brings up the debate about what type of valve should be used in women in reproductive age, and discusses the management of severe mitral stenosis and stenosis of a bioprosthetic valve during pregnancy. Surgical options can almost always be delayed until fetal maturity is achieved and a simultaneous cesarean section can be performed. However, under certain circumstances when the maternal welfare is in jeopardy the surgical intervention is mandatory even before the fetus reaches viability.

Cystic echinococcosis (CE) is a globally prevalent zoonotic disease. Demographic, clinical, laboratory, and follow-up data of patients between May 2009 and 2015 were retrospectively analyzed by screening data from a hospital automation system. A total of 238 (females, n=139 and males, n=99) patients with a mean age of 40.6±20.58 years were included. Less than half (40.8%) of the patients were living in the countryside. Hepatic involvement of CE was most frequently (72.2%) seen. A majority (75.6%) of the patients were symptomatic, but abdominal pain was the most frequently seen symptom. For diagnosis, in all patients, imaging modalities were used, while in 66% of the patients, serological methods were also employed. The patients received both medical and surgical treatments (78.5%, n=187), only surgical treatment (10.5%, n=25), or only medical treatment (8.8%, n=21). Surgical treatment was performed for patients with hepatic (n=139/176, 80.6%), pulmonary (n=78/94, 82.9%), splenic (n=7/9; 77.7%), and mesenteric (n=6/7, 85.1%) cysts, and patients cases with brain, bone, muscle, omentum, bladder, and adrenal cysts had undergone surgical intervention. Publication of regional data is important in terms of epidemiological considerations and may aid in the formulation of standard treatment approaches.

A method for assessing the accuracy of surgical technique in the correction of astigmatism.

Surgical results can be assessed as a function of what was aimed for, what was done, and what was achieved. One of the aims of refractive surgery is to reduce astigmatism; the smaller the postoperative astigmatism the better the result. Determination of what was done--that is, the surgical effect, can be calculated from the preoperative and postoperative astigmatism. A simplified formulation is described which facilitates the calculation (magnitude and direction) of this surgical effect. In addition, an expression for surgical accuracy is described, as a function of what was aimed for and what was achieved.

Class II treatment in adults: comparing camouflage orthodontics, dentofacial orthopedics and orthognathic surgery--a cephalometric study to evaluate various therapeutic effects.

It was the aim of this clinical study to compare the skeletal and dentoalveolar effects as well as those on the profile of three different treatment approaches in Class II patients (camouflage orthodontics, dentofacial orthopedics, and combined orthodontic and surgical treatment). Our study cohort consisted of 60 young adults presenting a skeletal Class II, Division 1 malocclusion: 20 patients whose overjet was reduced by camouflage following premolar extraction, 20 patients whose occlusions were corrected by placement of a fixed functional orthopedic appliance, and 20 who underwent orthognathic surgery (bilateral sagittal split osteotomy of the mandible without genioplasty). We documented the therapeutic progress using cephalometry. Each patient group achieved a reduction in overjet via their respective treatment. While no treatment-related changes in the maxillary area were assessable, the effects on the mandible differed. We observed advancement of the bony chin and an increase in mandibular length in the sagittal-diagonal dimension in the surgical and functional orthopedic groups. However, the extent of the treatment-related changes was significant only in the group of patients that had undergone orthognathic surgery. Only the surgical group presented changes in vertical relationships. Incisor repositioning as an outcome of the respective treatments differed fundamentally, with those in the surgical group revealing significant protrusion of the upper incisors. The maxillary incisors were retruded and mandibular incisors proclined in the functional orthopedic group, whereas the upper and lower incisors both retruded significantly in the extraction group. Soft-tissue remodeling bore no linear relationship to treatment-induced skeletal and dental effects. Still, orthognathic surgery led to the most marked profile changes. Treatment using fixed functional orthopedic appliances reduced the convexity of the soft-tissue profile at least moderately. Camouflage orthodontics, on the other hand, resulted in an increase in the nasolabial angle. In young adults fixed functional appliances are a treatment alternative to extraction therapy but to a lesser extent to orthognathic surgery. Because of their limited skeletal effects and minor changes in the profile they are indicated only in patients with a moderately severe Class II malocclusion. Pre-treatment proclined mandibular incisors limit the scope of indications for fixed functional appliances, as they can cause an increase in lower incisor proclination. Significant reductions in profile convexity are achievable only by combined orthodontic and surgical treatment of the malocclusion. When performing camouflage orthodontics in conjunction with maxillary premolar extractions in adults, an increase in the nasolabial angle, which is often esthetically undesirable, has to be discussed as a potential side effect and has to be taken into account when considering the different therapeutic approaches.

Paediatric obstructive sleep apnoea: is our operative management evidence-based?

Pabla, L; Duffin, J; Flood, L; Blackmore, K

2018-04-01

Despite the plethora of publications on the subject of paediatric obstructive sleep apnoea, there seems to be wide variability in the literature and in practice, regarding recourse to surgery, the operation chosen, the benefits gained and post-operative management. This may reflect a lack of high-level evidence. A systematic review of four significant controversies in paediatric ENT was conducted from the available literature: tonsillectomy versus tonsillotomy, focusing on the evidence base for each; anaesthetic considerations in paediatric obstructive sleep apnoea surgery; the objective evidence for the benefits of surgical treatment for obstructive sleep apnoea; and the medical treatment options for residual obstructive sleep apnoea after surgical treatment. There are many gaps in the evidence base for the surgical correction of obstructive sleep apnoea. There is emerging evidence favouring subtotal tonsillectomy. There is continuing uncertainty around the prediction of the level of post-operative care that any individual child might require. The long-term benefit of surgical correction is a particularly fertile ground for further research.

The aim of this study was to compare the visual outcomes, intraocular pressure (IOP), and endothelial cell loss caused by trabeculectomy (TRAB) and Ahmed glaucoma valve (AGV) implantation in patients who had previously undergone penetrating keratoplasty (PKP). The data from all patients who underwent surgical treatment of glaucoma after PKP were reviewed at the Cornea Department of Haydarpasa Numune Education and Research Hospital. Eighteen patients who had undergone surgical treatment of glaucoma after PKP were included in this retrospective study. Time between PKP and glaucoma surgeries, visual acuity results, IOP results, endothelial cell counts (ECC) before the surgery, at 1st, 6th, and 12th month of surgery were recorded. Differences between two groups were evaluated. Mean loss of ECC was 315 cells/mm(2) in the AGV group and 197 cells/mm(2) in TRAB group at 12th month of glaucoma surgery. The difference between endothelial cell loss at 12th month of surgery was statistically significant and higher in AGV group (p < 0.001). The decrease in IOP was 64.2 % in AGV group and 46.9 % in TRAB group at 12th month of surgery. Both differences were statistically significant between 2 groups (p = 0.001, 0.001). TRAB successfully decreased both the IOP and endothelial cell loss in patients with post-PKP glaucoma. Ahmed glaucoma valve had a significantly better IOP lowering but higher endothelial cell loss effect.

OBJECTIVE The object of this study was to assess the advantages and disadvantages of early nerve repair within 2 weeks following adult traumatic brachial plexus injury (ATBPI). METHODS From 2009 onwards, the authors have strived to repair as early as possible extended C-5 to C-8 or T-1 lesions or complete loss of C-5 to C-6 or C-7 function in patients in whom there was clinical and radiological suspicion of root avulsion. Among a group of 36 patients surgically treated in the period between 2009 and 2011, surgical findings in those who had undergone treatment within 2 weeks after trauma were retrospectively compared with results in those who had undergone delayed treatment. The result of biceps muscle reanimation was the primary outcome measure. RESULTS Five of the 36 patients were referred within 2 weeks after trauma and were eligible for early surgery. Nerve ruptures and/or avulsions were found in all early cases of surgery. The advantages of early surgery are as follows: no scar formation, easy anatomical identification, and gap length reduction. Disadvantages include less-clear demarcation of vital nerve tissue and unfamiliarity with the interpretation of frozen-section examination findings. All 5 early-treatment patients recovered a biceps force rated Medical Research Council grade 4. CONCLUSIONS Preliminary results of nerve repair within 2 weeks of ATBPI are encouraging, and the benefits outweigh the drawbacks. The authors propose a decision algorithm to select patients eligible for early surgery. Referral standards for patients with ATBPI must be adapted to enable early surgery.

Cataract surgery has undergone various advances since it was evolved from ancient couching to the modern phacoemulsification cataract surgery. Surgically induced astigmatism (SIA) remains one of the most common complications. The introduction of sutureless clear corneal incision has gained increasing popularity worldwide because it offers several advantages over the traditional sutured limbal incision and scleral tunnel. A clear corneal incision has the benefit of being bloodless and having an easy approach, but SIA is still a concern. In this study, we evaluated the SIA in clear corneal incisions with temporal approach and superior approach phacoemulsification. Comparisons between the two incisions were done using keratometric readings of preoperative and postoperative refractive status. It was a hospital-based prospective interventional comparative randomized control trial of 261 patients conducted in a rural-based tertiary care center from September 2012 to August 2014. The visual acuity and detailed anterior segment and posterior segment examinations were done and the cataract was graded according to Lens Opacification Classification System II. Patients were divided for phacoemulsification into two groups, group A and group B, who underwent temporal and superior clear corneal approach, respectively. The patients were followed up on day 1, 7, 30, and 90 postoperatively. The parameters recorded were uncorrected visual acuity, best-corrected visual acuity, slit lamp examination, and keratometry. The mean difference of SIA between 30th and 90th day was statistically evaluated using paired t -test, and all the analyses were performed using SPSS 18.0 (SPSS Inc.) software. The mean postoperative SIA in group A was 0.998 D on the 30th day, which reduced to 0.768 D after 90 days, and in group B the SIA after 30 days was 1.651 D, whereas it reduced to 1.293 D after 90 days. Temporal clear corneal incision is evidently better than superior clear corneal incision as far as SIA is concerned.

To define footwear outcomes following hallux valgus surgery, focusing on patient return to comfortable and heeled footwear and patterns of post-operative footwear selection. Surgical intervention is indicated for symptomatic cases of hallux valgus unresponsive to conservative methods, with favourable reported outcomes. The return to various types of footwear post-operatively is reflective of the degree of correction achieved, and corresponds to patient satisfaction. Patients are expected to return to comfortable footwear post-operatively without significant residual symptoms. Many female patients will additionally attempt to return to high-heeled, narrow toe box shoes. However, minimal evidence exists to guide their expectations. Sixty-five female hallux valgus patients that had undergone primary surgery between 2011 and 2013 were retrospectively identified using our hospital surgical database. Patients were reviewed using a footwear-specific outcome questionnaire at a mean 18.5 mo follow-up. Eighty-six percent of patients were able to return to comfortable footwear post-operatively with minimal discomfort. Of those intending to resume wearing heeled footwear, 62% were able to do so, with 77% of these patients wearing these as or more frequently than pre-operatively. No significant difference was observed between pre- and post-operative heel size. Mean time to return to heeled footwear was 21.4 wk post-operation. Cosmetic outcomes were very high and did not adversely impact footwear selection. We report high rates of return to both comfortable and heeled shoes in female patients following primary hallux valgus surgery. We observed an "all-or-none phenomenon" where patients rejected a return to heeled footwear unless able to tolerate them at the same frequency and heel size as pre-operatively. A minority of patients were unable to return to comfortable footwear post-operatively, which had adverse ramifications on their quality-of-life. We recommend that the importance of managing patient expectations through appropriate pre-operative counselling be emphasized in forefoot surgery.

Jaiswal, Rohit; Pu, Lee L Q

2012-04-01

Gynecomastia is a common disorder observed in male plastic surgery patients. Treatment options may include observation, surgical excision, or liposuction techniques. Congenital herniated nipple is a more rare condition, especially in male patients. We present the case of a 12-year-old boy with bilateral gynecomastia and herniated nipple-areolar complexes. A staged repair was undertaken in this patient with grade 2 gynecomastia. The first operation was ultrasonic liposuction bilaterally, yielding 200 mL of aspirate from the left and 400 mL on the right, to correct the gynecomastia. The second procedure, performed 6 months later, was a bilateral periareolar mastopexy to repair the herniated nipple-areolar complexes. The result of the first procedure was flattened and symmetrical breast tissue bilaterally, essentially a correction of the gynecomastia. The herniated nipples were still present, however. Bilateral periareolar mastopexies were then performed with resulting reduction of the herniations. There were no complications with either procedure, and a good cosmetic result was achieved. A staged surgical approach was successful in correcting both conditions with an excellent aesthetic result and the advantage of decreased risk for nipple complications.

Objective: To introduce a novel surgical technique for correction of adult congenital webbed penis. Methods: From March 2010 to December 2011, 12 patients (age range: 14–23 years old) were diagnosed as having a webbed penis and underwent a new surgical procedure designed by us. Results: All cases were treated successfully without severe complication. The operation time ranged from 20 min to 1 h. The average bleeding volume was less than 50 ml. All patients achieved satisfactory cosmetic results after surgery. The penile curvature disappeared in all cases and all patients remained well after 1 to 3 months of follow-up. Conclusions: Adult webbed penis with complaints of discomfort or psychological pressure due to a poor profile should be indicators for surgery. Good corrective surgery should expose the glans and coronal sulcus, match the penile skin length to the penile shaft length dorsally and ventrally, and provide a normal penoscrotal junction. Our new technique is a safe and effective method for the correction of adult webbed penis, which produces satisfactory results. PMID:22949367

Simplicity and treatment of the typical cleft hand.

Upton, J

2004-01-01

The typical cleft hand is now distinguished from symbrachydactyly. This review of the surgical treatment of 108 hands in 63 patients treated over a 28-year period concentrates upon the technical principles of surgical correction. The key to these reconstructions is a wide incision which extends from the ulnar side of the cleft around the malpositioned index finger to the thumb. This wide exposure provides clear identification of all anatomic structures within the palm. There are no tenuous flaps with narrow random pedicles. These difficult surgical corrections may often include index transposition, metacarpal and/or phalangeal osteotomies, joint releases, phalangeal ostectomies, preservation of the adductor pollicis muscle, first dorsal interosseous muscle release, syndactyly separation(s) and thumb duplication correction. Following reposition of all skeletal structures the dorsal and palmar full-thickness flaps are easily contoured to create a satisfactory first webspace. Outcomes data shows that although the pinch and grip remain weak, these hands are quite functional. It is important that the repositioned index ray not interfere with gripping and precision maneuvers between the mobile thumb and the ulnar two digits (ring and small) of the hand.

We evaluated our simulated major lung resection employing anatomically correct lung models as "off-the-job training" for video-assisted thoracic surgery trainees. A total of 76 surgeons voluntarily participated in our study. They performed video-assisted thoracic surgical lobectomy employing anatomically correct lung models, which are made of sponges so that vessels and bronchi can be cut using usual surgical techniques with typical forceps. After the simulation surgery, participants answered questionnaires on a visual analogue scale, in terms of their level of interest and the reality of our training method as off-the-job training for trainees. We considered that the closer a score was to 10, the more useful our method would be for training new surgeons. Regarding the appeal or level of interest in this simulation surgery, the mean score was 8.3 of 10, and regarding reality, it was 7.0. The participants could feel some of the real sensations of the surgery and seemed to be satisfied to perform the simulation lobectomy. Our training method is considered to be suitable as an appropriate type of surgical off-the-job training.

Surgical repair of total anomalous pulmonary venous connection (TAPVC) can be complicated by the development of pulmonary venous stenosis later on. In addition, the vertical vein, if left unligated, can remain patent and lead to hemodynamically significant left to right shunting. We report an infant who required transcatheter correction of both these problems after surgical repair of TAPVC.

[Update on upper eyelid blepharoplasty].

Klingenstein, A; Hintschich, C

2018-04-01

Upper eyelid blepharoplasty is among the most frequent oculoplastic surgical procedures. It is often performed as one of the first esthetic surgical interventions by surgeons of various disciplines. While there is a high probability of happy and satisfied patients postoperatively, there are important potential surgical complications that should be prevented. This requires a careful preoperative, perioperative and postoperative approach. This synopsis presents the basic considerations concerning upper eyelid blepharoplasty to serve as practical surgical guidelines. This is a compendium of important preoperative, perioperative and postoperative contemplations derived from the medical literature, expert opinions and the authors' personal experiences. Careful examination and documentation of eyelid and periorbital findings are required in order to identify additional pathologies to dermatochalasis and plan the surgical approach accordingly. There is a trend in the literature and in expert opinions away from large tissue resection and towards volume preserving and volume reconstructing surgical techniques. Correct placement of the skin fold as well as maintaining lid symmetry are crucial points in order to achieve a natural appearance and patient satisfaction. Careful and realistic patient information, state of the art surgery including cautious tissue resection and correct symmetrical formation of the skin fold as well as postoperative assistance and availability increase the likelihood of satisfied patients after blepharoplasty.

OBJECTIVE Infant hydrocephalus is estimated to affect more than 100,000 new infants each year in sub-Saharan Africa (SSA). Bugando Medical Centre (BMC), a government-funded and patient cost-shared referral center, serves over 13 million people in the Lake and Western regions of Tanzania. The goals of this study were to characterize the infant population affected by hydrocephalus who presented to BMC and were treated with a ventriculoperitoneal shunt (VPS) to determine the rate of early complications associated with this surgical procedure and to assess its potential risk factors. METHODS Data were prospectively collected from all patients less than 1 year of age who, over a period of 7 months, were diagnosed with hydrocephalus and admitted to BMC for insertion of a primary VPS. Demographic data, maternal history, preoperative studies, surgical procedure, and surgical complications developing by the time of the first follow-up visit were analyzed. Risk factors associated with the surgical complications were determined. RESULTS During the 7-month study period, 125 infants eligible for the study were included in the analysis. Overall, 75% were younger than 6 months of age, and 56% were males. Only 7% of mothers had a gestational ultrasound, 98% did not receive preconception folic acid, and 25% delivered their child at home. In most patients with hydrocephalus the etiology was uncertain (56%), and other patients had postinfectious (22.4%) or myelomeningocele-associated (16%) hydrocephalus. Patients' mean head circumference on admission was 51.4 ± 6.3 cm. Their median age at shunt surgery was 137 days, and 22.4% of the patients were operated on without having undergone radiological assessment. The majority of shunts were placed in a right parietooccipital location. Thirteen patients had undergone a previous intraventricular endoscopic procedure. Overall, at least one surgical complication was found in 33.6% of patients up to the first follow-up assessment (median follow-up time of 70 days); shunt infection was the most common complication. The postoperative mortality rate was 9%. The risk factors associated with early surgical complications were tumor-related etiology, larger head circumference, and postoperative hospital stays of greater duration. CONCLUSIONS In a region of the continent where most infant hydrocephalus cases had an uncertain etiology, most patients presented to the hospital in a late stage, with no prenatal diagnosis and with large head circumferences. Standard preoperative investigations were not uniformly performed, and the surgical complications, led by VPS infection, were disturbingly high. Younger patient age, previous endoscopic procedure, surgeon involved, and cranial location of the VPS had no statistical relation to the surgical complications. This study shows that the positive results previously reported by SSA mission hospitals, subspecialized in pediatric neurosurgery, are still not generalizable to every hospital in East Africa. To improve maternal and neonatal care in the Lake region of Tanzania, the development of a fluxogram to determine hydrocephalus etiology, a strict perioperative protocol for VPS insertion, and an increase in the number of endoscopic procedures are recommended to BMC.

Improving Functional and Aesthetic Outcomes in Syndromic Patients With Webbed Neck Deformity: Utilizing a Staged Endoscopic-Assisted Approach to Improve the Posterior Hairline and Decrease Scar Burden.

2017-06-01

Webbed neck deformity (WND) can have significant functional and psychosocial impact on the developing child. Surgical correction can be challenging depending on the extent of the deformity, and patients often also have low posterior hairlines requiring simultaneous correction. Current surgical techniques include various methods of single-stage radical excision that often result in visible scar burden and residual deformity. There is currently no general consensus of which technique provides the best outcomes. A modified approach to WND was designed by the senior author aimed to decrease scar burden. Endoscopic-assisted fasciectomy was performed with simultaneous posterior hairline reconstruction with local tissue rearrangement camouflaged within the hair-bearing scalp. Staged surgical correction was planned rather than correction in a single operation. A retrospective review was performed to evaluate all patients who underwent this approach over a 2-year period. Two patients underwent the modified approach, a 17-year-old female with Noonan syndrome and a 2-year-old female with Turner syndrome. Both patients showed postoperative improvement in range of motion, contour of the jaw and neckline, and posterior hairline definition. Patients were found to have decreased scar burden compared with traditional techniques. A staged, combination approach of endoscopic-assisted fasciectomy and strategic local tissue reconstruction of the posterior hairline to correct WND achieves good functional and aesthetic results and good patient satisfaction. This modification should be considered when managing WND.

Implementing AORN recommended practices for surgical attire.

Surgical attire is intended to protect both patients and perioperative personnel. AORN published the "Recommended practices for surgical attire" to guide perioperative RNs in establishing protocols for selecting, wearing, and laundering surgical attire. Perioperative RNs should work with vendors and managers to ensure appropriate surgical attire is available, model the correct practices for donning and wearing surgical attire, and teach team members about evidence-based practices. The recommendation that surgical attire not be home laundered is supported by evidence that perioperative nurses can share with their colleagues and managers to help support appropriate practices. Hospital and ambulatory surgery center scenarios have been included as examples of appropriate execution of these recommended practices. Copyright © 2012 AORN, Inc. Published by Elsevier Inc.

Gossypiboma is a term used to describe a mass that forms around a cotton sponge or abdominal compress accidentally left in a patient during surgery. Transmural migration of an intra-abdominal gossypiboma has been reported to occur in the digestive tract, bladder, vagina and diaphragm. Open surgery is the most common approach in the treatment of gossypiboma. However, gossypibomas can be extracted by endoscopy while migrating into the digestive tract. We report a case of intractable duodenal ulcer caused by transmural migration of gossypiboma successfully treated by duodenorrhaphy. A systemic literature review is provided and a scheme of the therapeutic approach is proposed. A 61-year-old Han Chinese man presented with intermittent epigastric pain for the last 10 months. He had undergone laparoscopic cholecystectomy conversion to open cholecystectomy for acute gangrenous cholecystitis 10 months ago at another hospital. Transmural migration of gossypiboma into the duodenum was found. Endoscopic intervention failed to remove the entire gauze, and duodenal ulcer caused by the gauze persisted. Surgical intervention was performed and the gauze was removed successfully. The penetrated ulcer was repaired with duodenorrhaphy. The postoperative period was uneventful.We systematically reviewed the literature on transmural migration of gossypiboma into duodenum and present an overview of published cases. Our PubMed search yielded seven reports of transmural migration of retained surgical sponge into the duodenum. Surgical interventions were necessary in two patients. Transmural migration of gossypiboma into the duodenum is a rare surgical complication. The treatment strategies include endoscopic extraction and surgical intervention. Prompt surgical intervention should be considered for emergent conditions such as active bleeding, gastrointestinal obstruction, or intra-abdominal sepsis. For non-emergent conditions, surgical intervention could be considered for intractable cases in which endoscopic extraction failed.

Although a rerupture after surgical clipping of ruptured intracranial aneurysms is rare, it is associated with high morbidity and mortality. The causes for retreatment and rupture after surgical clipping are not clearly defined. From a prospectively maintained database of 244 patients who had undergone surgical clipping of ruptured intracranial aneurysms, we selected patients who experienced retreatment or rerupture within 30 days after surgical clipping. Aneurysm occlusions were examined by microvascular Doppler ultrasonography and indocyanine green video-angiography. Indications for retreatment included rerupture and partial occlusion. We analyzed the characteristics and causes of early retreatment. Six patients (2.5%, 95% CI 0.9 to 5.3%) were retreated within 30 days after surgical clipping, including two patients (0.8%, 95% CI 0.1 to 2.9%) who experienced a rerupture. The retreated aneurysms were found in the anterior communicating artery (AcomA) (n = 5) and basilar artery (n = 1). Retreatment of the AcomA (7.5%) was performed significantly more frequently than that of other arteries (0.56%) (p < 0.01). A laterally projected AcomA aneurysm (17.4%) was more frequently retreated than were other aneurysm types (2.3%). Cases of laterally projecting AcomA aneurysms tended to result from an incomplete clip placed using a pterional approach from the opposite side of the aneurysm projection. Despite developments, the rates of retreatment and rerupture after surgical clipping remain similar to those reported previously. Retreatment of the AcomA was significantly more frequent than was retreatment of other arteries. Patients underwent retreatment more frequently when they were originally treated for lateral type aneurysms using a pterional approach from the opposite side of the aneurysm projection. The treatment method and evaluation modalities should be considered carefully for AcomA aneurysms in particular.

Infective endocarditis has been reported post Melody percutaneous pulmonary valve implant; the incidence and risk factors, however, remain poorly defined. We identified four cases of endocarditis from our first 25 Melody implants. Our aim was to examine these cases in the context of postulated risk factors and directly compare endocarditis rates with local surgical valves. We conducted a retrospective review of patients post Melody percutaneous pulmonary valve implant in New Zealand (October, 2009-May, 2015) and also reviewed the incidence of endocarditis in New Zealand among patients who have undergone surgical pulmonary valve implants. In total, 25 patients underwent Melody implantation at a median age of 18 years. At a median follow-up of 2.9 years, most were well with low valve gradient (median 27 mmHg) and only mild regurgitation. Two patients presented with life-threatening endocarditis and obstructive vegetations at 14 and 26 months post implant, respectively. Two additional patients presented with subacute endocarditis at 5.5 years post implant. From 2009 to May, 2015, 178 surgical pulmonic bioprostheses, largely Hancock valves and homografts, were used at our institution. At a median follow-up of 2.9 years, four patients (2%) had developed endocarditis in this group compared with 4/25 (16%) in the Melody group (p=0.0089). Three surgical valves have been replaced. The Melody valve offers a good alternative to surgical conduit replacement in selected patients. Many patients have excellent outcomes in the medium term. Endocarditis, however, can occur and if associated with obstruction can be life threatening. The risk for endocarditis in the Melody group was higher in comparison with that in a contemporaneous surgical pulmonary implant cohort.

General Surgery consultant recruitment poses considerable challenges in Model 3 Hospitals in Ireland. The aim of this paper is to examine General Surgery activity and consultant staffing in order to inform future manpower and service planning. General surgical activity in Model 3 Hospitals was examined using the validated 2014 Hospital Inpatient Enquiry (HIPE) dataset. Current consultant staffing was ascertained from hospital personnel departments and all trainees on the National Surgical Training Programme were asked to complete a questionnaire on their career intentions. Model 3 Hospitals accounted for 50% of all General Surgery discharges. In the elective setting, 51.5% of all procedures were endoscopic investigations and in the acute setting only 22% of patients underwent an operation. Most surgical procedures were of low acuity and included excision of minor lesions, appendicectomy, cholecystectomy and hernia repair. Of 76 General Surgeons who work in Model 3 Hospitals 25% were locums and 54% had not undergone formal training in Ireland. A further 22% of these surgeons will retire in the next five years. General Surgical trainees surveyed indicated an unwillingness to take up posts in Model 3 Hospitals, while 83% indicated that a post in a Model 4 Hospital is 'most desirable'. Lack of attractiveness related to issues regarding rotas, lack of ongoing skill enhancement, poor experience in the management of complex surgical conditions, limited research and academic opportunity, isolation from colleagues and poor trainee support. These data indicated that an impending General Surgery consultant manpower crisis can only be averted in Model 3 Hospitals by either major change in the emphasis of surgical training or a significant reorganisation of surgical services.

Different etiologies for recurrent pregnancy loss have been identified, among them are: anatomical, endocrine, genetic, chromosomal and thrombophilia pathologies. To assess medical and obstetric characteristics, and pregnancy outcomes, among women with uterine abnormalities and recurrent pregnancy loss (RPL). This study also aims to assess the impact of uterine anatomic surgical correction on pregnancy outcomes. A retrospective case control study of 313 patients with two or more consecutive pregnancy losses followed by a subsequent (index) pregnancy. Anatomic abnormalities were detected in 80 patients. All patients were evaluated and treated in the RPL clinic at Soroka University Medical Center. Out of 80 patients with uterine anatomic abnormalities, 19 underwent surgical correction, 32 did not and 29 had no clear record of surgical intervention, and thus were excluded from this study. Women with anatomic abnormalities had a higher rate of previous cesarean section (18.8% vs. 8.6%, P=0.022), tended to have a lower number of previous live births (1.05 vs. 1.37, P=0.07), and a higher rate of preterm delivery (22.9% vs. 10%, P=0.037). Using multivariate logistic regression analysis, anatomic abnormality was identified as an independent risk factor for RPL in patients with previous cesarean section after controlling for place of residence, positive genetic/autoimmune/endocrine workup, and fertility problems (OR 7.22; 95% CI 1.17-44.54, P=0.03). Women suffering from anatomic abnormalities tended to have a higher rate of pregnancy loss compared to those without anatomic abnormalities (40% vs. 30.9%, P=0.2). The difference in pregnancy loss rate among women who underwent surgical correction compared to those who did not was not statistically significant. In patients with previous cesarean section, uterine abnormality is an independent risk factor for pregnancy loss. Surgical correction of uterine abnormalities among RPL patients might have the potential to improve live birth rate.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign neoplasm that occurs almost exclusively in the nasopharynx of adolescent male individuals. We performed a retrospective study to determine the efficacy and safety of preoperative embolization and the surgical outcome in patients with JNA in a single-center institution. Fifteen cases undergoing embolization and surgical treatment between April 2003 and February 2013 were evaluated retrospectively. The demographic data, clinical presentation, and treatment were reviewed including the kind of preoperative embolization and different surgical approaches performed. The parameters investigated were the amount of blood loss, the tumor stage, and the rates of recurrence. Subsequently, a comparison was made between patients who had undergone Onyx ® embolization versus those who had been embolized with the standard approach. In these 15 patients (mean age, 15 years), a total of 27 surgical procedures were performed. One patient was at stage Ia, two were at stage Ib, two were at stage IIa, six were at stage IIb, one was at stage IIc, and three were at stage IIIa based on the Radkowsky classification. All patients underwent preoperative embolization and subsequent surgery. The surgical approach and the embolization technique varied and evolved during time. The embolization procedure decreased the intraoperative blood loss to a minimum of 250 ml, and with the advent of intratumoral embolization, the rate of recurrence diminished. Preoperative Onyx ® embolization facilitates the shift in the treatment to endoscopic excision in selected patients, which reduces recurrence rates and overall morbidity.

The aim of this study was to propose an appropriate surgical treatment for diabetic forefoot osteomyelitis (DFO) involving ischemia or moderate to severe soft tissue infection. The records of 28 patients with osteomyelitis from 2009 to 2015 were retrospectively studied. All patients had undergone surgery based on preoperative magnetic resonance imaging examinations and histopathological or culture analyses confirming the surgical bone margin. The appropriate surgical margin, crucial factors for early healing, and prognosis after complete resection of osteomyelitis were examined. After healing, patients were followed up to assess prognosis (range 32-1,910 days, median 546 days). The healing rate of nonischemic cases of DFO with negative surgical margins was 100% and that of ischemic cases was 84.6%; the ambulatory rates for both types of cases were 100%. No wound (and/or osteomyelitis) recurrence was observed. Nine new cases of DFO developed in six patients (21.4%; eight were due to vascular stenosis, and one was due to biomechanical changes in the foot. After complete resection of osteomyelitis, preoperative and postoperative C-reactive protein levels and the size of the ulcer were significant predictors of early healing (p < 0.05, 0.01, and 0.05, respectively). The appropriate surgical margin should be set in the area of bone marrow edema, based on magnetic resonance imaging examinations after revascularization. In cases with high preoperative or postoperative C-reactive protein levels, long-term antibiotic therapy is recommended, and surgery should be planned after the C-reactive protein levels decrease, except in emergencies. © 2016 by the Wound Healing Society.

This paper illustrates the results of surgical correction in 11 cases with orbital deformities such as periorbital deficiency after orbitotomy for retinoblastoma and orbital malposition after facial trauma. EH composite material, mixture of hydroxyapatite and epoxide acrylate maleic resin in constant proportion, was used as a good bone graft substitute in all 11 cases. This material was easier to be molded during surgery, safe to human body, had no toxic effects, no irritation and no implant-related complications. The early results obtained in these patients are encouraging.

Orthognathic surgery has become an acceptable treatment plan for patients with various maxillofacial deformities. The rehabilitation of severe class III adult patients requires a complex interdisciplinary orthodontic and orthognathic approach. This presentation aims to show a case of combination of camouflage and bilateral sagittal split osteotomy (BSSO).Camouflage in maxillary arch was accepted after analysing visual treatment objective (VTO) and pleasing soft tissue compensation which gave us the clue to go ahead for surgical correction of excess mandibular length to achieve best aesthetic outcome while maintaining nature’s compensation in upper arch.

Three dogs presented for evaluation of acute onset tachypnoea and dyspnoea following episodes of vomiting and/or regurgitation. Thoracic radiographs were suggestive of a gastro-oesophageal intussusception in all three dogs; one dog also showed evidence of aspiration pneumonia. All three dogs underwent surgical correction with a bilateral incisional gastropexy. All dogs recovered from anaesthesia uneventfully and were discharged from the hospital 3 days after presentation. Persistent megaoesophagus was evident in all three dogs, and they are being chronically managed with a strict feeding regime and pro-motility agents. © 2015 British Small Animal Veterinary Association.

The natural history of congenitally corrected transposition of the great arteries.

PubMed

Huhta, James

2011-01-01

The natural history of congenitally corrected transposition of the great arteries is of clinical/surgical importance once the fetus is born without heart block or signs of heart failure. Without significant tricuspid valve malformation, associated defects such as ventricular septal defect and left ventricular outflow obstruction can be repaired surgically. The mortality and long-term outcome appear to be linked strongly with the severity of tricuspid valve regurgitation. Some patients with an intact ventricular septum and no right ventricular dysfunction will live long lives without detection, and some women will successfully complete pregnancy.

Treating the Proximal Interphalangeal Joint in Swan Neck and Boutonniere Deformities.

PubMed

Fox, Paige M; Chang, James

2018-05-01

Swan neck and boutonniere deformities of the proximal interphalangeal (PIP) joint are challenging to treat. In a swan neck deformity, the PIP joint is hyperextended with flexion at the distal interphalangeal (DIP) joint. In a boutonniere deformity, there is flexion the PIP joint with hyperextension of the DIP joint. When the deformities are flexible, treatment begins with splinting. However, when the deformity is fixed, serial casting or surgery is often necessary to restore joint motion before surgical correction. Many surgical techniques have been described to treat both conditions. Unfortunately, incomplete correction and deformity recurrence are common. Published by Elsevier Inc.

The aim of this study was to analyze and compare the surgical data, clinical outcomes, and complications between three-column osteotomy (3-COS) and standard surgical management (SSM) for the treatment of adult spine deformity (ASD). A total of 112 patients who underwent consecutive 3-COS (n = 48) and SSM (n = 64) procedures for ASD correction at a single institution from 2001 to 2011 were reviewed in this study. The outcomes were assessed using the Scoliosis Research Society (SRS)-22 scores. The complications of patients with 3-COS and SSM were also compared. No significant differences were found in patient characteristics between SSM and 3-COS groups. Surgical data and radiographic parameters showed that the patients of the 3-COS group suffered more severe ASD than those of the SSM group. The distribution of surgical complications revealed that SSM group underwent more complications than 3-COS groups with no significant differences. At final follow-up, the total SRS-22 score of SSM was not significant between pre-operation and post-operation. However, the total SRS-22 score of 3-COS at final follow-up was significantly higher than pre-operation. For severe ASD patients with high grade pelvic incidence (PI), pelvic tilt (PT), and PI/lumbar lordosis (LL) mismatch and who have subjected to spine surgeries more than twice before, 3-COS might be more effective than SSM in improving the clinical outcomes. However, due to the higher reoperation rate of 3-COS, SSM may be more appropriate than SSM for correcting the not serious ASD patients.

One and a half ventricular repair as an alternative for hypoplastic right ventricle.

Maluf, Miguel Angel; Carvalho, Antonio Carlos; Carvalho, Werther Brunow

2010-01-01

Patients with complex congenital heart disease, characterized by right ventricle hypoplasia, had a palliative surgical option with one and a half ventricular repair. From July 2001 to March 2009, nine patients (mean age 5.2 years, range 3 to 9 years) with hypoplastic right ventricle, underwent correction with one and a half ventricle technique. Preoperative diagnoses included: pulmonary atresia with intact ventricular septum, in six and Ebstein's anomaly, in three cases. Six patients had bidirectional cavo-pulmonary shunt (Glenn operation) previously. The surgical approach was performed with cardiopulmonary bypass to correct intracardiac defects: atrial septal defect closure (nine cases); right ventricle outlet tract reconstruction with porcine pulmonary prosthesis (seven cases); tricuspid valvuloplasty (three cases). There was one (11.1%) hospital death. All the patients left the hospital in good clinical conditions. One patient presented pulmonary stenosis at distal prosthesis anastomosis and needed surgical correction. There was one (12.5%) late deaths after reoperation. At mean follow-up of 39.8 months (range 16 months to 8.4 years) seven patients are alive in functional class I (NYHA). Surgical treatment of congenital cardiac anomalies in the presence of a hypoplastic right ventricle by means of one and a half ventricle repair has the advantages of reducing the surgical risk of biventricular repair compared to the Fontan circulation; it maintains a low right atrium pressure, a pulsatile pulmonary blood flow and improves the systemic oxygen saturation with short and medium-term promising results. Longer follow-up is needed to prove the efficacy of such a repair in the long term.

Dupuytren's disease is one of the fibro-proliferative conditions affecting the palmar and digital fascia. This disease has been known to surgeons and treated by them for at least 200 years. Dupuytren's disease is very common in Northern Europe and also in countries inhabited by immigrants from Northern Europe. Dupuytren's contracture is stated to be uncommon in Indian subcontinent and very little has been written about this disease in India. The authors have however come across 30 patients with Dupuytren's contracture and they are the subject of this paper, with special emphasis on its surgical correction and complications of surgical treatment. Patients were categorized into stages I, II and III as per the severity of disease. Regional fasciectomy was performed in 90% of the patients and extensive fasciectomy in 10% of patients. Most of wounds were closed by primary closure with z-plasty. In rest of the patients free skin grafts were used to close the wound, when primary closure was not possible. The patients were followed up regularly for 5 years and the results of surgical treatment were categorized into excellent, good, fair and poor. The results were excellent in 23 patients (76.66%), good in six patients (20%) and fair in one patient (3.33%). Post operative edema and some stiffness was seen in two patients. Wound infection was seen in one patient and haematoma in one patient. The correct surgical technique and meticulous post operative care is needed to achieve higher rates of correction and to limit the complications and recurrence.

Recently, lower thrombin generation has been associated with excess bleeding post-cardiopulmonary bypass (CPB). Therefore, treatment to correct thrombin generation is a potentially important aspect of management of bleeding in this group of patients. The objective of the present study was to investigate the effects of fresh frozen plasma (FFP), recombinant factor VIIa (rFVIIa), prothrombin complex concentrate (PCC) and tissue factor pathway inhibitor (TFPI) inhibition on thrombin generation when added ex vivo to the plasma of patients who had undergone cardiac surgery requiring CPB. Patients undergoing elective cardiac surgery were recruited. Blood samples were collected before administration of heparin and 30 min after its reversal. Thrombin generation was measured in the presence and absence of different concentrations of FFP, rFVIIa, PCC and an anti-TFPI antibody. A total of 102 patients were recruited. Thrombin generation following CPB was lower compared with pre-CPB (median endogenous thrombin potential pre-CPB 339 nmol/l per min, post-CPB 155 nmol/l per min, P < 0.0001; median peak thrombin pre-CPB 35 nmol/l, post-CPB 11 nmol/l, P < 0.0001). Coagulation factors and anticoagulants decreased, apart from total TFPI, which increased (55-111 ng/ml, P < 0.0001), and VWF (144-170 IU/dl, P < 0.0001). Thrombin generation was corrected to pre-CPB levels by the equivalent of 15 ml/kg FFP, 45 μg/kg rFVIIa and 25 U/kg of PCC. Inhibition of TFPI resulted in an enhancement of thrombin generation significantly beyond pre-CPB levels. This study shows that FFP, rFVIIa, PCC and inhibition of TFPI correct thrombin generation in the plasma of patients who have undergone surgery requiring CPB. Inhibition of TFPI may be a further potential therapeutic strategy for managing bleeding in this group of patients.

The correct and timely referral of patients, from peripheral hospitals, without specialized surgical care, namely in hand surgery, like Plastic Surgery or Orthopedics is of crucial importance. The authors report the case of a patient that presents in the Plastic Surgery Department with a chronic infection of the hypothenar eminence of the right hand. The clinical history suggests the persistence of a foreign body, despite two previous surgical procedures for removal, performed in the residence hospital. Surgical exploration was performed and the foreign body was removed without complications. The intent of this presentation is to alert for the importance of the timely referral of patients that can benefit of specialized care, namely of plastic surgery, when this is no possible in the residence hospital, in view of better health care and better patient treatment.

Diagnosis, treatment and outcome of orbital neoplasia in dogs: a retrospective study of 44 cases.

Hendrix, D V; Gelatt, K N

2000-03-01

Forty-four dogs with confirmed orbital neoplasia were studied. Eighteen tumour types were represented and 95 per cent of the neoplasms were classified as malignant. The tumour types most commonly diagnosed were osteosarcoma, fibrosarcoma and nasal adenocarcinoma. Thirty-six per cent of the dogs had at least one clinical sign that was compatible with a diagnosis of orbital abscessation or cellulitis. Fifty-six per cent of the dogs, where follow-up information was available, were euthanased or had died within six months of diagnosis, while 19 per cent of the total were still alive after one year post-diagnosis. Cytological examination was diagnostic for orbital neoplasia in 49 per cent of the fine needle aspirates of the retrobulbar space. In contrast, 56 per cent of the non-surgical biopsies were diagnostic for orbital neoplasia. Of those dogs that had died or been euthanased within six months of diagnosis, only 22 per cent had undergone some form of therapy for orbital neoplasia. In comparison, 86 per cent of dogs surviving longer than six months post-diagnosis had undergone such therapy.

To describe the historical evolution of the role of lasers in effecting therapeutic changes in the four acellular membranes of the eye. Over the past 50 years, iterative developments have been instituted in lasers used for various forms of eye surgery predominately on the basis of data generated in early experiments in the 1960s to determine thresholds for damage and their incorporation in codes of practice for laser safety. The evolutionary steps are described. Excimer laser technology resulted in the generation of the new field of laser refractive surgery with over 40 million individuals now having undergone procedures such as photorefractive keratectomy and LASIK. Developments in lasers used for various forms of retinal surgery have undergone changes involving shorter and shorter pulse durations together with changes in beam energy distribution with implications for potential intervention in AMD prophylactically. Lasers have made a major impact on surgical treatment on all four acellular membranes of the eye but particularly Bowman's membrane in refractive surgery, where it has been demonstrated that it can be removed without significant consequences for eye health or vision.

To describe the preoperative and postoperative experience of children who have undergone heart-lung transplantation for cystic fibrosis. Retrospective descriptive study. Paediatric Surgical Unit, Harefield Hospital, Middlesex, Great Britain. Twelve children less than 15 years of age (mean age 11 years 10 months; range 7 to 14 years), six boys and six girls, who received heart-lung transplants between September 1987 and March 1991. All 12 children were alive and well 1 year after surgery, although one girl had undergone retransplantation in the eighth postoperative month. Actuarial survival rate was 66% at 2 years. Early results suggest that heart-lung transplantation is a successful therapeutic option for children with cystic fibrosis. Cystic fibrosis-related postoperative complications were malabsorption of immunosuppressive drugs, meconium ileus equivalent, and persisting infection in the upper respiratory tract. These and general complications of acute rejection and infection did not prevent 66% of the group from returning to their normal schooling within the first postoperative year. Obliterative bronchiolitis remains the most serious late complication after lung transplantation, and further research is needed into treatment and prevention.

Optimal surgical management of severe tricuspid regurgitation in cardiac transplant patients.

Severe tricuspid regurgitation (TR) with signs of right-sided heart failure is rare after orthotopic heart transplantation (OHT). In some instances, this condition will require surgical correction using reconstructive surgery or prosthetic valve replacement. Repair techniques of atrioventricular valves are now well described. However, the results of the different surgical procedures in this setting have not been widely reported and may depend on the type of valvular dysfunction and lesions present. Herein we report our experience in a group of patients requiring surgical correction of symptomatic severe TR after OHT. We reviewed our transplant experience during the period from July 1992 to July 1999 (n = 138 cardiac transplants). Eight patients (5.8%) developed symptomatic severe TR requiring surgical correction after a mean duration of 21 months after OHT. Patients were divided into 2 groups based on the mechanism of regurgitation using Carpentier's functional classification. In Group 1 (n = 4), the mechanism of tricuspid regurgitation was Carpentier's Type I, secondary to annular dilation. In Group 2 (n = 4) the mechanism of TR was leaflet prolapse (Type II), due to chordal rupture after biopsy injury. Initially, tricuspid valve integrity was surgically restored in all 8 patients with either valve repair (n = 6) or replacement (n = 2). In Group 1, 2 patients underwent valve repair using a ring annuloplasty and 2 patients underwent valve replacement with a bioprosthetic valve (n = 1) or pulmonary allograft (n = 1). In Group 2, all patients underwent valve repair using a variety of techniques in combination with tricuspid annuloplasty. During the follow-up period, 3 of the 6 (50%) primary repairs (1 patient in Group 1 and 2 in Group 2) failed and required replacement with a bioprosthesis at 8 days, 14 days and 4 years, respectively. The pulmonary allograft failed secondary to valvular stenosis and was replaced with a bioprosthesis after 10 months. Overall, no failures occurred in any of the 5 bioprosthetic valves placed at the primary operation (n = 1) or after failed tricuspid repair/pulmonary allograft (n = 4), after a mean follow-up of 55 months. TR requiring surgical correction after OHT is a rare condition and requires a tailored surgical strategy. This strategy should take into account the mechanism of valve dysfunction and specific valvular lesions. In patients with Type I dysfunction secondary to annular dilation, valve repair with a remodeling annuloplasty should be performed; however, in the presence of any residual TR on transesophageal echocardiography (TEE) at the completion of cardiopulmonary bypass (CPB), a valve replacement with a bioprosthesis is warranted during the same procedure. In patients with Type II dysfunction with leaflet prolapse and biopsy-induced chordal injury, a bioprosthetic valve replacement seems a reliable surgical option.

Individuals with rheumatoid arthritis are at higher risk for infection than the general population, and surgical site infection after spinal surgery in this population can result in clinically significant complications. The goal of this study was to identify risk factors for acute surgical site infection after spinal surgery in patients with rheumatoid arthritis who were treated with nonbiologic (conventional) disease-modifying antirheumatic drugs (DMARDs) alone or with biologic DMARDs. All patients treated with biologic agents were treated with nonbiologic agents as well. The authors performed a retrospective, single-center review of 47 consecutive patients with rheumatoid arthritis who underwent spinal surgery and had follow-up of 3 months or longer. The incidence of surgical site infection was examined, and multivariate logistic regression analysis was performed to test the association of surgical site infection with putative risk factors, including the use of biologic agents, methotrexate, and prednisolone, as well as the duration of rheumatoid arthritis, the presence of diabetes, patient age, length of surgery, and number of operative levels. After spinal surgery, 14.89% (7 of 47) of patients had surgical site infection. Use of methotrexate and/or prednisolone, patient age, diabetes, duration of rheumatoid arthritis, length of surgery, number of operative levels, and use of biologic DMARDs did not significantly increase the risk of infection associated with spinal surgery. All patients who had surgical site infection had undergone spinal surgery with instrumentation. The findings show that greater attention to preventing surgical site infection may be needed in patients with rheumatoid arthritis who undergo spinal surgery with instrumentation. To the authors' knowledge, this is the first study to show that the use of biologic agents did not increase the incidence of surgical site infection after spinal surgery in patients with rheumatoid arthritis.

Acute surgical patients are particularly vulnerable to human error. The Acute Physiological Support Team (APST) was created with the twin objectives of identifying high-risk acute surgical patients in the general wards and reducing both the incidence of error and impact of error on these patients. A number of error taxonomies were used to understand the causes of human error and a simple risk stratification system was adopted to identify patients who are particularly at risk of error. During the period November 2012-January 2013 a total of 101 surgical patients were cared for by the APST at Edendale Hospital. The average age was forty years. There were 36 females and 65 males. There were 66 general surgical patients and 35 trauma patients. Fifty-six patients were referred on the day of their admission. The average length of stay in the APST was four days. Eleven patients were haemo-dynamically unstable on presentation and twelve were clinically septic. The reasons for referral were sepsis,(4) respiratory distress,(3) acute kidney injury AKI (38), post-operative monitoring (39), pancreatitis,(3) ICU down-referral,(7) hypoxia,(5) low GCS,(1) coagulopathy.(1) The mortality rate was 13%. A total of thirty-six patients experienced 56 errors. A total of 143 interventions were initiated by the APST. These included institution or adjustment of intravenous fluids (101), blood transfusion,(12) antibiotics,(9) the management of neutropenic sepsis,(1) central line insertion,(3) optimization of oxygen therapy,(7) correction of electrolyte abnormality,(8) correction of coagulopathy.(2) CONCLUSION: Our intervention combined current taxonomies of error with a simple risk stratification system and is a variant of the defence in depth strategy of error reduction. We effectively identified and corrected a significant number of human errors in high-risk acute surgical patients. This audit has helped understand the common sources of error in the general surgical wards and will inform on-going error reduction initiatives. Copyright © 2013 Surgical Associates Ltd.

Paralleling the growth of bariatric surgery, the demand for post-bariatric body-contouring surgery is increasing and placing additional burdens on already strained health care systems. In Austria, medically necessary body contouring is covered by public health care. In a sample of 622 women, we assessed the proportion of patients that underwent post-bariatric surgery at least 2 years after gastric bypass. Former bariatric patients were asked whether they had undergone post-bariatric surgery or were planning to do so by structured telephone interviews. For patients who had undergone body contouring, the degree of satisfaction with the results was inquired. Costs for bariatric and post-bariatric procedures were assessed. Of 622 patients, 93 (14.9 %) had undergone body contouring and 68 (10.9 %) considered a procedure, while 454 (73 %) definitely stated that they did not want plastic surgery. Cost coverage was declined in 7 patients (1.1 %). Plastic procedures (n = 101) included 65 abdominoplasties, 25 lower body lifts without thigh lifts, 7 brachioplasties, and 4 minor procedures. Forty-nine patients were very satisfied with the results, 28 were fairly satisfied, and 16 were not satisfied. Body contouring added about 6 % to the costs of surgical treatment for morbid obesity. Fewer patients than in other studies expressed a desire for post-bariatric surgery, 15 % actually proceeded to this step. The low demand was neither due to denied coverage nor to unfavourable results of plastic surgery. Additional costs for body contouring were less than expected.

To investigate the attributes of service users associated with uptake of medical abortion (MA) versus manual vacuum aspiration (MVA) at public health facilities in Vietnam. Structured exit interviews were conducted among women who underwent termination at 62 public health facilities in Hanoi, Khanh Hoa, and Ho Chi Minh City (HCMC) between August and December 2011. Data on sociodemographic, abortion-related, and service-related factors were compared between women who underwent MVA versus MA. Overall, 1233 women completed the study survey: 541 (43.9%) from Hanoi; 163 (13.2%) from Khanh Hoa; and 529 (42.9%) from HCMC. Almost one-quarter of women (23.1%) had chosen MA. After controlling for sociodemographic factors, women living in Khanh Hoa (odds ratio [OR], 13.4; 95% confidence interval [CI], 5.3-33.8) and HCMC (OR, 5.8; 95% CI, 2.1-15.9) were more likely to have undergone MA than women in Hanoi. Older women were less likely to have undergone MA (P < 0.05), and those who had previously heard of MA were twice as likely to have undergone MA (P = 0.020). Uptake of MA was lower than that of MVA and varied by province. Women in Vietnam will make their own judgment about which method to choose if they have prior knowledge of both.

Thoracic-lumbar vertebral fracture is very common in clinic, and late post-traumatic kyphosis is the main cause closely related to the patients' life quality, which has evocated extensive concern for the surgical treatment of the disease. This study aimed to analyze the clinical outcomes and surgical strategies for late post-traumatic kyphosis after failed thoracolumbar fracture operation. All patients presented back pain with kyphotic apex vertebrae between T12 and L3. According to Frankel classification grading system, among them, 3 patients were classified as grade D, with the ability to live independently. A systematic review of 12 case series of post-traumatic kyphosis after failed thoracolumbar fracture operation was involved. Wedge osteotomy was performed as indicated-posterior closing osteotomy correction in 5 patients and anterior open-posterior close correction in 7 patients.Postoperatively, thoracolumbar x-rays were obtained to evaluate the correction of kyphotic deformity, visual analog scales (VAS) and Frankel grading system were used for access the clinical outcomes. All the patients were followed up, with the average period of 38.5 months (range 24-56 months). The Kyphotic Cobb angle was improved from preoperative (28.65 ± 11.41) to postoperative (1.14 ± 2.79), with the correction rate of 96.02%. There was 1 case of intraoperative dural tear, without complications such as death, neurological injury, and wound infection. According to Frankel grading system, no patient suffered deteriorated neurological symptoms after surgery, and 2 patients (2/3) experienced significant relief after surgery. The main VAS score of back pain was improved from preoperative (4.41 ± 1.08) to postoperative (1.5 ± 0.91) at final follow-up, with an improvement rate of 65.89%. Surgical treatment of late post-traumatic kyphosis after failed thoracolumbar fracture operation can obtain good radiologic and clinical outcomes by kyphosis correction, decompression, and posterior stability.

Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three-column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68-year-old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side. Resect the unilateral facet joint, and retain contralateral structure integrity. Protect the spinal cord, nerve root. Clear sequestrum, necrotic tissue, abscess of paravertebral and intervertebral space. Specially designed titanium mesh cages or bone blocks were implanted into interbody. Fix both side rods and compress both sides to make the mesh cages and bone blocks tight. Reconstruct posterior column structure with allogeneic bone and autologous bone. Using this technique, the procedures of debridement, spinal cord decompression, deformity correction, bone grafting, and internal fixation can be completed with only one incision and surgical position, and the deformity correction efficiency is higher than anterior surgery. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

Over the past two centuries the surgical profession has undergone a profound evolution in terms of efficiency and outcomes. Societal concerns in relation to quality assurance, patient safety and cost reduction have highlighted the issue of training expert surgeons. The core elements of a training model build on the basic foundations of gross and fine motor skills. In this paper we provide an analysis of the ergonomic principles involved and propose relevant training techniques. We have endeavored to provide both the trainer and trainee perspectives. This paper is structured into four sections: 1) Pre-operative preparation issues, 2) technical skills and instrument handling, 3) low fidelity simulation models and 4) discussion of current concepts in crew resource management, deliberate practice and assessment. Rehearsal, warm-up and motivation-enhancing techniques aid concentration and focus. Appropriate posture, comprehension of ergonomic principles in relation to surgical instruments and utilisation of the non-dominant hand are essential skills to master. Low fidelity models can be used to achieve significant progress through the early stages of the learning curve. Deliberate practice and innate ability are complementary to each other and may be considered useful adjuncts to surgical skills development. Safe medical care requires that complex patient interventions be performed by highly skilled operators supported by reliable teams. Surgical ergonomics lie at the heart of any training model that aims to produce professionals able to function as leaders of a patient safety oriented culture.

To compare pelvic limb joint kinematics and temporal gait characteristics during land-based and aquatic-based treadmill walking in dogs that have undergone surgical stabilisation for cranial cruciate ligament deficiency. Client-owned dogs with surgically stabilised stifles following cranial cruciate ligament deficiency performed three walking trials consisting of three consecutive gait cycles on an aquatic treadmill under four water levels. Hip, stifle and hock range of motion; peak extension; and peak flexion were assessed for the affected limb at each water level. Gait cycle time and stance phase percentage were also determined. Ten client-owned dogs of varying breeds were evaluated at a mean of 55·2 days postoperatively. Aquatic treadmill water level influenced pelvic limb kinematics and temporal gait outcomes. Increased stifle joint flexion was observed as treadmill water level increased, peaking when the water level was at the hip. Similarly, hip flexion increased at the hip water level. Stifle range of motion was greatest at stifle and hip water levels. Stance phase percentage was significantly decreased when water level was at the hip. Aquatic treadmill walking has become a common rehabilitation modality following surgical stabilisation of cranial cruciate ligament deficiency. However, evidence-based best practice guidelines to enhance stifle kinematics do not exist. Our findings suggest that rehabilitation utilising a water level at or above the stifle will achieve the best stifle kinematics following surgical stifle stabilisation. © 2017 British Small Animal Veterinary Association.

To evaluate the surgical outcomes of the implantation of an additional Ahmed glaucoma valve (AGV) into the eyes of patients with refractory glaucoma following previous AGV implantation. This study is a retrospective review of the clinical histories of 23 patients who had undergone a second AGV implantation after a failed initial implantation. Age, sex, prior surgery, glaucoma type, number of medications, intraocular pressure (IOP), visual acuity, and surgical complications were analyzed. Surgical success was defined as IOP maintained below 21 mm Hg, with at least a 20% overall reduction in IOP, regardless of the use of IOP-lowering medications. Following the implantation of a second AGV, the mean IOP decreased from 39.3 to 18.5 mm Hg (52.9% reduction, P<0.001). The mean number of postoperative IOP-lowering medications administered decreased from 2.8 to 1.7 after the second AGV implantation (P<0.001). The cumulative probability of success for the procedure was 87% after 1 year and 52% after 3 years. Three patients (13.0%) experienced bullous keratopathy after the second AGV implantation. None of the patients showed any evidence of diplopia or ocular movement limitation as a result of the presence of 2 AGVs in the same eye. Prior trabeculectomy was found to be a significant risk factor for failure (P=0.027). A second AGV implantation can be a good choice of surgical treatment when the first AGV has failed to control IOP.

The incidence of gram-negative multi-drug-resistant (MDR) infections is increasing worldwide. This study sought to determine the incidence, clinical profiles, risk factors, and mortality of these infections in general surgery patients. All general surgery patients with a clinical infection by gram-negative MDR bacteria were studied prospectively for a period of five years (2007-2011). Clinical, surgical, and microbiologic parameters were recorded, with a focus on the identification of risk factors for MDR infection and mortality. Incidence of MDR infections increased (5.6% to 15.2%) during the study period; 106 patients were included, 69.8% presented nosocomial infections. Mean age was 65 ± 15 years, 61% male. Extended-spectrum β-lactamases (ESBL) Escherichia coli was the most frequent MDR bacteria. Surgical site infections and abscesses were the most common culture locations. The patients presented multiple pre-admission risk factors and invasive measures during hospitalization. Mortality was 15%, and related to older age (odds ratio [OR] 1.07), malnutrition (OR 13.5), chronic digestive conditions (OR 4.7), chronic obstructive pulmonary disease (OR 3.9), and surgical re-intervention (OR 9.2). Multi-drug resistant infections in the surgical population are increasing. The most common clinical profile is a 65-year-old male, with previous comorbidities, who has undergone a surgical intervention, intensive care unit (ICU) admission, and invasive procedures and who has acquired the MDR infection in the nosocomial setting.

Recent data demonstrate that surgical lung biopsy in immunocompromised children, including oncology patients, alters therapy in only 50% of cases. We hypothesized that there are factors identifiable preoperatively which can predict the patients who will or will not benefit from surgical biopsy. We reviewed the medical records of all children with malignancy who underwent surgical lung biopsy between 2004 and 2013 at a single institution, excluding those children who had previously undergone a solid organ or bone marrow transplant. Eighty lung wedge biopsies were performed (median age 13 years, IQR 5.25-16; 63% male, n=50) 53 (66%) of which led to a change in patient management. The majority of biopsies were performed to diagnose a new mass or differentiate infection from metastases (mass group) (n=68, 85%), and 12 biopsies (15%) were performed to diagnose a known infection for antibiotic guidance (infection group). Children in the infection group were more likely to be febrile preoperatively, were more likely to be an inpatient preoperatively, and had a lower absolute neutrophil count at the time of biopsy. Patients in the infection group had higher postoperative mortality rates and higher rates of major complications. In pediatric oncology patients, surgical lung biopsy has a lower diagnostic yield and higher complication rate when performed for antibiotic guidance. Prior to proceeding with biopsy in this high-risk patient population, surgeons and oncologists should carefully weigh the potential risks and benefits. Copyright © 2015 Elsevier Inc.

2017-01-01

The authors present a systematic review of randomized and observational, retrospective and prospective studies to compare between robotic surgery as opposed to laparoscopic, abdominal, and vaginal surgery for the treatment of both benign and malignant gynecologic indications. The comparison focuses on operative times, surgical outcomes, and surgical complications associated with the various surgical techniques. PubMed was the main search engine utilized in search of study data. The review included studies of various designs that included at least 25 women who had undergone robotic gynecologic surgery. Fifty-five studies (42 comparative and 13 non-comparative) met eligibility criteria. After careful analysis, we found that robotic surgery was consistently connected to shorter post-surgical hospitalization when compared to open surgery, a difference less significant when compared to laparoscopic surgery. Also, it seems that robotic surgery is highly feasible in gynecology. There are quite a few inconsistencies regarding operative times and estimated blood loss between the different approaches, though in the majority of studies estimated blood loss was lower in the robotic surgery group. The high variance in operative times resulted from the difference in surgeon’s experience. The decision whether robotic surgery should become mainstream in gynecological surgery or remain another surgical technique in the gynecological surgeon’s toolbox requires quite a few more randomized controlled clinical trials. In any case, in order to bring robotic surgery down to the front row of surgery, training surgeons is by far the most important goal for the next few years. PMID:28467761

A computed tomographic study. To investigate the changed anatomic relationship between the superior mesenteric artery and the aorta in surgically treated ankylosing spondylitis (AS) patients with thoracolumbar kyphosis. Superior mesenteric artery syndrome in kyphosis patients after surgery has been reported. To date, the changed aortomesenteric angle and distance in AS patients undergoing surgical correction of kyphosis have not yet been addressed. Thirty-three AS patients with thoracolumbar kyphosis subjected to pedicle subtraction osteotomy were prospectively recruited. Radiographic measurements included global kyphosis (GK), thoracic kyphosis (TK), local kyphosis (LK), and lumbar lordosis. The aortomesenteric angle and distance were measured on both preoperative and postoperative computed tomography images. The height and weight of these patients were also recorded. The average height significantly increased from 159.7±5.1 cm before surgery to 167.2±5.3 cm after surgery (P<0.001), whereas the average weight changed from 59.3±6.8 kg to 59.5±6.9 kg (P>0.05). GK, TK, LK, and lumbar lordosis were corrected from 77.7, 40.2, 19.4, and 2.8 degrees before surgery to 37.1, 38.4, -21.9, and -32 degrees after surgery, respectively. All the changes of these parameters were found to be significantly different (P<0.001) except that of TK (P>0.05). With the correction of kyphosis, the aortomesenteric angle significantly decreased from 29.3 to 23.4 degrees (P<0.001), whereas the aortomesenteric distance significantly decreased from 25.7 to 20.4 mm (P<0.001). It is to be noted that the changes of GK, LK, and height were significantly correlated with the decrements of aortomesenteric angle and distance (P<0.05). The correlations of the surgical correction of kyphosis and the decreased aortomesenteric angle and distance in AS patients were quantitatively confirmed by our study. Spine surgeons should be aware of the potential risk for the development of superior mesenteric artery syndrome after kyphosis correction in AS patients.

Predictors of emotional functioning in youth after surgical correction of idiopathic scoliosis.

Patients with idiopathic scoliosis, although otherwise healthy, often have significant concerns about their self-image and appearance. In a group of juveniles and adolescents, this can impact adjustment in school, functioning in peer groups, and general sense of well-being. There are limited data to help physicians reliably and precisely identify those who are at higher risk of poor emotional adjustment even after spine deformity correction. The purpose of this study was to determine the predictors of emotional maladjustment in juvenile and adolescent patients after surgical correction of idiopathic scoliosis. A total of 233 juveniles, mean age 11.26 ± 1.02 (range, 8 to 12) years and 909 adolescents, mean age 14.91 ± 1.61 (range, 13 to 21) years, who underwent surgical correction for idiopathic scoliosis and who were participating in a prospective longitudinal multicenter database, were enrolled in the study. Participants completed the Scoliosis Research Society-22 (SRS-22) questionnaire before surgery and 2 years postoperatively. Radiographs were used to measure Cobb angle and surface measurements were used to determine decompensation and trunk shift. Adolescents reported poorer mental health preoperatively (P<0.05) and 2 years postoperatively (P<0.001) than juveniles; however, both groups reported improved mental health (P<0.001) and self-image (P<0.01) postoperatively. Mental health 2 years postoperatively was predicted by preoperative self-image (P<0.05), mental health (P<0.001), and main thoracic Cobb angle (P<0.05) in the juvenile group. Within the adolescent group, mental health 2 years postoperatively was predicted by preoperative mental health (P<0.001); self-image 2 years postoperatively was predicted by preoperative mental health (P<0.01) and self-image (P<0.001). Self-image and mental health are significantly improved after spine deformity correction in juveniles and adolescents with idiopathic scoliosis. However, consistent with normative development, adolescents are at higher risk for emotional maladjustment than juveniles. Surgical decision making in scoliosis correction should take the emotional status of the patient into consideration.

We report a surgical case of tension pyopneumothorax in a patient who was receiving chemotherapy for esophageal cancer. A 68-year-old man who had undergone total gastrectomy with splenectomy for gastric cancer and was receiving chemotherapy for esophageal cancer was presented to our hospital with dyspnea. Left tension pyopneumothorax was diagnosed, and he received left lower lobectomy after pleural drainage. His postoperative course was uneventful, and he is alive without any cancer recurrences 5 years after the lobectomy. Once tension pyopneumothorax has developed from lung abscess, emergent lobectomy may be a useful option to prevent lethal aspiration pneumonia.

Probe, Robert

2016-08-01

One of the most frequent complications after intraarticular fracture of the calcaneus is the development of posttraumatic arthritis of the subtalar joint. If conservative measures fail in the treatment of this condition, consideration of arthrodesis should be given. This video depicts the preoperative assessment and surgical technique applied to one such 54-year-old patient who had undergone internal fixation of a calcaneal fracture 9 years before. Shown within the video is exposure of the subtalar joint through a lateral incision, joint preparation, and the application of stable fixation. Subtleties of exposure, osteogenesis maximization, and postoperative management are covered.

Shoulder balance for adolescent idiopathic scoliosis (AIS) patients is associated with patient satisfaction and self-image. However, few validated systems exist for selecting the upper instrumented vertebra (UIV) post-surgical shoulder balance. The purpose is to examine the existing UIV selection criteria and correlate with post-surgical shoulder balance in AIS patients. Patients who underwent spinal fusion at age 10-18 years for AIS over a 6-year period were reviewed. All patients with a minimum of 1-year radiographic follow-up were included. Imbalance was determined to be radiographic shoulder height |RSH| ≥ 15 mm at latest follow-up. Three UIV selection methods were considered: Lenke, Ilharreborde, and Trobisch. A recommended UIV was determined using each method from pre-surgical radiographs. The recommended UIV for each method was compared to the actual UIV instrumented for all three methods; concordance between these levels was defined as "Correct" UIV selection, and discordance was defined as "Incorrect" selection. One hundred seventy-one patients were included with 2.3 ± 1.1 year follow-up. For all methods, "Correct" UIV selection resulted in more shoulder imbalance than "Incorrect" UIV selection. Overall shoulder imbalance incidence was improved from 31.0% (53/171) to 15.2% (26/171). New shoulder imbalance incidence for patients with previously level shoulders was 8.8%. We could not identify a set of UIV selection criteria that accurately predicted post-surgical shoulder balance. Further validated measures are needed in this area. The complexity of proximal thoracic curve correction is underscored in a case example, where shoulder imbalance occurred despite "Correct" UIV selection by all methods.

Macrolane (large particle biphasic hyaluronic acid) filler injection for correction of defect contour after liposuction.

PubMed

Cerqua, Sandro; Angelucci, Francesco

2013-08-01

In a minority of patients undergoing liposuction, superficial irregularities (or skin depression) in the operated area may occur. Macrolane is a gel composed of hyaluronic acid (HA), used for volume restoration of soft tissues. In this study, the authors investigated the effectiveness, maintenance, and safety of Macrolane as a "non-surgical" treatment to correct skin depression after liposuction. Twelve female patients were included. Macrolane was injected at a subdermal superficial plane using an intramuscular or spinal needle. In all patients, Macrolane was successful in correcting skin depression. No relevant side effects were observed. At 8 months post-injection, a persistence of correction of 60-70% was still present in 90% of the patients. In conclusion, Macrolane filler injections are a predictable, safe, and long-lasting non-surgical procedure to fill contour defects that arise after liposuction, and represent a good option for patients who refuse to undergo an additional surgery to fill the arisen skin depressions.

Face expressive lifting (FEL): an original surgical concept combined with bipolar radiofrequency.

2014-01-01

Aging can lead to changes in facial expressions, transforming the positive youth expression of happiness to negative expressions as sadness, tiredness, and disgust. Local skin distension is another consequence of aging, which can be difficult to treat with rejuvenation procedures. The "face expressive lifting" (FEL) is an original concept in facial rejuvenation surgery. On the one hand, FEL integrates established convergent surgical techniques aiming to correct the age-related negative facial expressions. On the other hand, FEL incorporates novel bipolar RF technology aiming to correct local skin distension. One hundred twenty-six patients underwent FEL procedure. Facial expression and local skin distension were assessed with 2 years follow-up. There was a correction of negative facial expression for 96 patients (76 %) and a tightening of local skin distension in 100 % of cases. FEL is an effective procedure taking into account and able to correct both age-related negative changes in facial expression and local skin distension using radiofrequency. Level of Evidence: Level IV, therapeutic study.

Assessment of technical dexterity is currently the weakest issue in surgical evaluation. It is imperative to develop an objective exam that allows us to correct training deficiencies and abilities and to objectively feedback education programs and hospitals. The purpose of this study was to perform a correlation between theoretical knowledge and surgical skills. We performed a national pilot study in in surgeons certifying by the Mexican Board of Surgery in 2010. This was a two-stage study: written exam (stage I) and oral exam (viva voce) to all surgeons approving the written exam (stage II). In stage II we utilized an objective structured assessment of technical skills (OSATS) whose results were correlated with those of the written and oral exams. The assessment involved seven skill stations and a global rating scale to indicate correctly performed or not and a fail/pass exam, respectively. Sixty-two surgeons approved the written exam in two places. We found no statistical difference among skills in open surgery (bowel anastomosis, liver and vascular suture), laparoscopic surgery (grape pilling, cutting a circle and intracorporeal knot tying) and instrument identification. There was a statistically significant difference (p <0.001) when median values were compared between laparoscopic surgery vs. open surgery and the identification of surgical instruments. There was a correlation between theoretical knowledge and surgical skills. When applying an OSATS, we found a positive correlation between theoretical knowledge and surgical skills. This assessment proves to to be valid and reliable for the evaluation of surgical dexterity.

This study evaluated the differences in surgical changes and post-surgical changes between bi-cortical and mono-cortical osteosynthesis (MCO) in the correction of skeletal Class III malocclusion with bilateral sagittal split osteotomies (BSSOs). Twenty-five patients had bi-cortical osteosynthesis (BCO), 32 patients had mono-cortical fixation. Lateral and postero-anterior cephalometric radiographs, taken at the time of surgery, before surgery, 1 month after surgery, and on completion of orthodontic treatment (mean 9.9 months after surgery), were obtained for evaluation. Cephalometric analysis and superimposition were used to investigate the surgical and post-surgical changes. Independent t-test was performed to compare the difference between the two groups. Pearson's correlations were tested to evaluate the factors related to the relapse of the mandible. The sagittal relapse rate was 20% in the bi-cortical and 25% in the mono-cortical group. The forward-upward rotation of the mandible in the post-surgical period contributed most of the sagittal relapse. There were no statistically significant differences in sagittal and vertical changes between the two groups during surgery and in the post-surgical period. No factors were found to correlate with post-surgical relapse, but the intergonial width increased more in the bi-cortical group. The study suggested that both methods of skeletal fixation had similar postoperative stability. Copyright © 2011 International Association of Oral and Maxillofacial Surgeons.

2017-08-01

To report a patient with cyclic esotropia with a high accommodative convergence to accommodation (AC/A) ratio after surgical correction of intermittent exotropia who was found to have bilateral anomalous medial rectus muscle insertion sites. A 5-year-old girl developed intermittent esotropia on alternating days after undergoing bilateral lateral rectus recessions for correction of intermittent exotropia. Alternate prism and cover measurement of ocular alignment and binocular function was assessed on consecutive days. Surgical correction was performed for the full amount measured on a "crossed" day. On "straight" days, her eyes were orthotropic with normal binocular vision. Examination on "crossed" days revealed a left esotropia of 75 prism diopters (PD) at near fixation and 40 PD at distance fixation in primary gaze without fusion or stereopsis. The patient underwent bilateral medial rectus recessions in conjunction with posterior fixation sutures (MRP). During surgery, the distance from the limbus to the medial rectus muscle insertion was 3.5 mm bilaterally. Postoperatively, the cycle was broken, and the esotropia disappeared with no recurrence at the latest follow-up at 12 months. MRP is an effective procedure for correction of cyclic esotropia with a high AC/A ratio. Strabismus surgeons should design surgical strategies based on preoperative measurement of deviations at all distances and the anatomy of muscle insertions in patients with cyclic esotropia.

Rehabilitation of Adolescents with Scoliosis During Growth - Preliminary Results Using a Novel Standardized Approach in Russia. (Methodology).

The aim of this study is to evaluate the effect of a Schroth Best Practice® program in an out-patient regimen on the signs of scoliosis in patients with adolescent idiopathic scoliosis (hereafter referred to as AIS). The second aim is to evaluate in-brace correction with the Gensingen Brace® in the first sample of patients with AIS. Both authors have undergone training in this special approach to scoliosis rehabilitation. The first author has undergone PT (physical therapy) and CAD-CAM (computer-aided design and manufacturing)bracing training, the second author PT training. 23 patients with AIS, 19 girls and 4 boys, with an average age of 13.6 years, average Risser sign of 2.52 and an average Cobb angle of 36.9 degrees (20-88 degrees), underwent an out-patient Schroth Best Practice® program with an intensity of two days a week of 2 x 60 min sessions/day. The angle of trunk rotation (ATR) was measured before and after the course. Eleven of the patients were fit with Gensingen Braces®. Braces were produced via CAD-CAM. In-brace correction was measured and compared with initial data. After an out-patient Schroth Best Practice® program ATR was reduced significantly from 9.58 degrees to 7.47 degrees in thoracic and from 8.9 to 6.6 degrees in lumbar. An average in-brace correction of 59% was achieved in CADCAM braces. The results achieved with out-patient rehabilitation in the investigations published previously are repeatable. The deformity of the trunk can be reduced significantly after out-patient rehabilitation according to Schroth Best Practice® standards. In-brace correction comparable with published results on CAD-CAM bracing can be achieved in braces according to Gensingen® standards after appropriate training. Out-patient rehabilitation following the Schroth Best Practice® standards seems to provide an improvement of signs of scoliosis patients in this study using a pre-/post prospective design. The results of the recent studies on Schroth Best Practice® program seem to be repeatable. Following appropriate training, the in-brace corrections achieved with the CAD / CAM technology can be compared to the in-brace corrections as published in recent literature. CAD / CAM allows for repeatable results globally.

Ergotamine-induced complex rectovaginal fistula. Report of a case.

This report stresses the importance of local complications caused by ergotamine abuse for the treatment of migraine headaches. We present an unusual case of a complex rectovaginal fistula (RVF) caused by long-term ergotamine suppository abuse. A 39-year-old female was referred after she had undergone a transverse colostomy for temporary fecal diversion. Evaluation, including proctoscopy, gastrograffin enema, vaginogram, and pelvic computerized tomography revealed a RVF 6 cm proximal to the dentate line with distal rectal stricture. Surgical intervention included take down of the transverse colostomy with reanastomosis, proctectomy with excision of the fistula, creation of a colonic "J-pouch" with a coloanal anastomosis, and construction of a temporary loop ileostomy. The patient had an uneventful recovery, and her ileostomy was closed three months later. Pathologic examination of the surgical specimen failed to reveal any specific etiology of the RVF. However, her ten-year use of up to five ergotamine suppositories per day for migraine treatment is associated with a local ischemic effect. Pathophysiology of this rare cause of RVF and the surgical procedure are discussed. If evidence of any side effects of ergotamine suppositories is seen, early discontinuation of the drug should be considered to avoid complications such as RVF and/or strictures.

We assessed the outcomes of gender-affirming surgery (GAS, or sex-reassignment surgery) 4 to 6 years after first clinical contact, and the associations between postoperative (dis)satisfaction and quality of life (QoL). Our multicenter, cross-sectional follow-up study involved persons diagnosed with gender dysphoria (DSM-IV-TR) who applied for medical interventions from 2007 until 2009. Of 546 eligible persons, 201 (37%) responded, of whom 136 had undergone GAS (genital, chest, facial, vocal cord and/or thyroid cartilage surgery). Main outcome measures were procedure performed, self-reported complications, and satisfaction with surgical outcomes (standardized questionnaires), QoL (Satisfaction With Life Scale, Subjective Happiness Scale, Cantril Ladder), gender dysphoria (Utrecht Gender Dysphoria Scale), and psychological symptoms (Symptom Checklist-90). Postoperative satisfaction was 94% to 100%, depending on the type of surgery performed. Eight (6%) of the participants reported dissatisfaction and/or regret, which was associated with preoperative psychological symptoms or self-reported surgical complications (OR = 6.07). Satisfied respondents' QoL scores were similar to reference values; dissatisfied or regretful respondents' scores were lower. Therefore, dissatisfaction after GAS may be viewed as indicator of unfavorable psychological and QoL outcomes.

Accelerated treatment protocols: full arch treatment with interim and definitive prostheses.

PubMed

Drago, Carl

2012-01-01

With the advent of titanium, root form implants and osseointegration, dental treatment has undergone a metamorphosis in recent years. These new techniques enable dentists to provide anchorage for various kinds of prostheses that improve masticatory function, esthetics, and comfort for patients. Implant treatment protocols have been improved relative to implant macro- and micro-geometries, surgical and prosthetic components, and treatment times. Over the past 20 years, immediate occlusal function (also known as loading) has been established as a predictable treatment modality, provided certain specific criteria are met. In many cases, edentulous patients, crippled by the loss of their teeth, can undergo outpatient surgical and prosthetic procedures and return to a masticatory function that is near normal--sometimes after only one day of surgical and prosthetic treatment. This treatment option is also available for patients with advanced, generalized periodontal disease. Computer-assisted design/Computer-assisted manufacturing (CAD/CAM) has transformed how dental prostheses are made, offering improved accuracy, longevity, and biocompatibility; along with reduced labor costs and fewer complications than casting technologies. This article reviews the principles associated with immediate occlusal loading and illustrates one specific accelerated prosthodontic treatment protocol used to treat edentulous and partially edentulous patients with interim and definitive prostheses.

Surgical transposition of the ovaries: imaging findings in 14 patients.

PubMed

Kier, R; Chambers, S K

1989-11-01

Pelvic radiation therapy for cervical or vaginal cancer often leads to ovarian failure. To remove the ovaries from the radiation portal and preserve their function, they can be transposed to the lateral abdomen. Serial imaging studies in 14 patients who had undergone ovarian transposition (five bilateral, nine unilateral) were reviewed. Images obtained included 32 CT scans, 20 sonograms, and one MR image. Most transposed ovaries were located along the paracolic gutters near the iliac crests, creating an extrinsic mass effect on adjacent bowel. Detection of surgical clips on the ovary on CT scans allowed confident recognition of all 19 transposed ovaries. Cysts in the transposed ovaries, noted on most imaging studies, did not correlate with complications of pain or hormonal dysfunction. In one case, a large physiologic cyst in a transposed ovary distorted the cecum and was mistaken for a mucocele of the appendix. In another case, a large ovarian cyst was thought to be tumor recurrence or a lymphocele. These findings indicate that although the transposed ovaries can be recognized on CT scans by the surgical clips attached to the ovaries, the appearance of the ovary does not predict reliably the development of complications.

A case report of bilateral pharyngoceles without a history of elevated intrapharyngeal pressures is used to support the hypothesis that pharyngoceles may be an adult manifestation of an internal branchial sinus anomaly. The development of a pharyngocele from a branchial sinus origin would suggest a predictable relationship to the hypoglossal, glossopharyngeal, and superior laryngeal nerves, which may influence the choice of surgical approach (open versus endoscopic) and the counseling of patients who are considering surgical correction.

Surgical management of cross-bites in orthognathic surgery: Surgically assisted rapid maxillary expansion (SARME) versus two-piece maxilla.

Seeberger, Robin; Gander, Evelyn; Hoffmann, Jürgen; Engel, Michael

2015-09-01

The surgical treatment of cross-bites includes surgically-assisted maxillary expansion (SARME) or maxillary-bipartition during bimaxillary surgery. This study evaluates and compares the changes in the teeth and lower nasal passage, as well as the stability of the expansion. The measurements were performed on the cone-beam computed tomography (CBCT) scans of 32 patients with transverse (width) deficiencies of the maxilla. To expand the maxilla, 12 patients underwent the two-piece maxilla method, while 20 patients received SARME. The mean distraction width for SARME was 6.8 mm (SD 3.7), while that for the two-piece maxilla was 4.1 mm (SD 1.6). The expansion with SARME was over the entire length of the maxilla, from anterior to posterior, whereas the expansion of the two-piece patient group was only in the posterior part of the maxilla. The segments of the maxilla opened nearly parallel in SARME, while they were reverse V-shaped in the two-piece maxilla, from anterior to posterior. A key point in the planning of combined orthodontic-orthognathic therapy with surgical correction of a cross-bite is the precise determination of the area where the width needs to be increased, and the amount of correction needed to treat the patient using minimal surgical procedures.

Tsai, Tsung-Han; Peng, Kai-Ling; Lin, Chien-Jen

2017-01-01

Background Laser in situ keratomileusis (LASIK) is the most common and popular procedure performed for the correction of refractive errors in the last two decades. We report a case of traumatic flap displacement with flap folding which occurred 3 years after LASIK was performed. Previous literature suggests that vision prognosis would be closely related to proper and prompt management of traumatic flap displacement with flap folding 3 years after LASIK. Case presentation A 23-year-old female presented to our hospital who had undergone uneventful LASIK in both eyes 3 years prior. Unfortunately, she had suffered a blunt trauma in her right eye in a car accident. A late onset of corneal flap displacement was found with upper and lower portion of the flap being folded inside the corneal bed. Surgical intervention for debridement with subsequent reposition of corneal flap was performed as soon as possible in the operating room. A bandage contact lens was placed, and topical antibiotic and corticosteroids were given postoperatively. Two days after the operation, the displaced corneal flap was found to be well attached smoothly on the corneal bed without folds. The best-corrected visual acuity was 6/6 with refraction of −0.75 D to 1.0 D ×175° in her right eye 1 month later. Literature review We reviewed a total of 19 published cases of late-onset traumatic flap dislocations or displacements after LASIK with complete data from 2000 to 2014. Conclusion Traumatic displacement of corneal flaps after LASIK may occur after blunt injury with specific direction of force to the flap margin, especially tangential one. According to the previous literature, late-onset traumatic flap displacement may happen at any time after LASIK and be caused by various types of injuries. Fortunately, good visual function could mostly be restored with immediate and proper management. PMID:28458585

This study presents a statistical review of corrective surgery for cleft palate, based on cases treated at the maxillo-facial surgery units of the Pediatrics Hospital of the Centro Médico Nacional and at Centro Médico La Raza of the National Institute of Social Security of Mexico, over a five-year period. Interdisciplinary management as performed at the Cleft-Palate Clinic, in an integrated approach involving specialists in maxillo-facial surgery, maxillar orthopedics, genetics, social work and mental hygiene, pursuing to reestablish the stomatological and psychological functions of children afflicted by cleft palate, is amply described. The frequency and classification of the various techniques practiced in that service are described, as well as surgical statistics for 188 patients, which include a total of 256 palate surgeries performed from March 1984 to March 1989, applying three different techniques and proposing a combination of them in a single surgical time, in order to avoid complementary surgery.

MANAGEMENT OF OMPHALOPHLEBITIS AND UMBILICAL HERNIA IN THREE NEONATAL GIRAFFE (GIRAFFA CAMELOPARDALIS).

2015-12-01

Umbilical disorders, including omphalophlebitis, omphaloarteritis, external umbilical abscesses, urachal abscesses, patent urachus, and umbilical hernias, represent a significant challenge to the health and well-being of a neonate. The three neonatal giraffe (Giraffa camelopardalis) in this report were evaluated for umbilical swellings. Two developed omphalophlebitis, and one had an uncomplicated umbilical hernia. Omphalophlebitis is an inflammation and/or infection of the umbilical vein. Giraffe calves with a failure of passive transfer may be predisposed and should be thoroughly evaluated for the condition. Umbilical hernias result from a failure of the umbilical ring to close after parturition or from malformation of the umbilical ring during embryogenesis. These problems were surgically corrected for all three individuals, although one died due to postsurgical complications. The risks involved include anesthetic complications, surgical dehiscence, and maternal rejection. Early detection and surgical intervention are recommended for the correction of omphalophlebitis and umbilical hernias in neonatal giraffe.

We describe a surgical technique for the correction of isolated congenital lenticular coloboma associated with high corneal astigmatism. Transscleral fixation of the capsular bag with a single eyelet Cionni capsular tension ring was followed by in-the-bag implantation of a toric intraocular lens (IOL). This lead to complete correction of the lenticular defect and perfect alignment of the toric lens. In this case, the child attained an unaided distance visual acuity of 20/30 following amblyopia therapy and a well-aligned toric IOL at 12 months of follow-up. This technique can be used in cases with concomitant lenticular coloboma and significant corneal astigmatism.

To restore sinus rhythm in the remaining heart chambers of six adult patients with atrial septal defect and chronic or paroxysmal atrial fibrillation, electrical, right atrial isolation associated with surgical correction of the defect was performed. All but one patient was free from atrial fibrillation without medication 2-25 months after operation. The isolated right atrial appendages showed intrinsic rhythmical activity in five patients and no electrical activity in one. Right atrial isolation is a safe and effective procedure that abolishes atrial fibrillation in patients with arrhythmia after surgical correction of atrial septal defect.

A comparison is made of the preoperative and postoperative speech evaluations of 15 selected subjects who had pharyngeal flap operations combined with palatal pushback. Postoperatively, 13 of the 15 patients (86 percent) showed no abnormal nasal emission and no evidence of significant hypernasality during word production. Gross substitution errors were also corrected by the surgical repair. While the number of patients is small, this study indicates equal effectiveness of the surgical technique described--regardless of the sex, the medical diagnosis, whether the procedure was primary or secondary, or the amount of postoperative time--providing there is good function of the muscles of the soft palate.

The present report describes a male patient with a unilateral cleft lip and palate who presented with midfacial anteroposterior and transverse deficiency. Correction involved a two-stage surgical-orthodontic approach: asymmetric anterior distraction of the segmented maxilla followed by two-jaw surgery (LeFort I and bilateral sagittal splitting ramus osteotomies). The present case demonstrates that the asymmetric elongation of the maxilla with anterior distraction is an effective way to correct a transversely distorted alveolar form and midfacial anteroposterior deficiency. Furthermore, successful tooth movement was demonstrated in the new bone created by distraction.

Varus deformity of the proximal humerus in children is a little known pathology due to its low incidence of presentation. Progress has been made in recent years in understanding the possible etiology and pathophysiological causes. Radiological criteria for diagnosis and functional impairment that occurs have also been defined. However, there are few reports in the literature about the surgical treatment of this deformity in children. In this paper we present a case of surgical treatment of this deformity by corrective osteotomy fixed with precontoured external maleolar plate osteosynthesis. Copyright © 2013 SECOT.

2016-10-01

To investigate surgical outcomes and complications of scoliosis associated with Marfan syndrome. Inclusion criteria were patients who were 10-20 years of age, had a diagnosis of Marfan syndrome by the Ghent nosology, had scoliosis and had undergone spinal fusion, and had at least 2 years of postoperative follow-up. The medical records of all patients were reviewed for age at the time of surgery, surgical procedures performed, instrumentation type, estimated blood loss (EBL) during surgery, operation time and complications related to surgery. Health-related quality-of-life measures (obtained with the SRS-22 Questionnaire before operation and at the last clinical follow-up) were also recorded. Patients were analyzed as two different groups, Group 1 and Group 2, according to the different approaches employed. Patients receiving combined anterior and posterior surgery were assigned to Group 1 and those who received posterior-only surgery to Group 2. Group 1 consisted of 30 patients (14 males, 16 females) with a mean age at surgery of 16.8 years (range: 10-20 years). Complications in Group 1 included two cases of instrumentation loosening with one removed, one case of instrumentation breakage and one case of chylothorax and hemothorax during video assisted thoracoscopic release. 66 patients (28 males, 38 females) with a mean age at surgery of years 16.4 years (range: 10-20 years) were included in Group 2. Complications in Group 2 included six cases of cerebro-spinal fluid leak, one case of deep wound infection secondary to cerebro-spinal fluid leak, one case of leg weakness and one case of pleural rupture cause by misplacement of pedicle screw. There is no difference of age at surgery, preoperative Cobb angles, and SRS-22 total scores (3.0 vs. 3.1) between the two groups (P > 0.05). Group 1 yielded larger correction rate than Group 2 for both thoracic (62.5 % vs. 56.2 %) and lumbar scoliosis (68.3 % vs. 62.7 %). Loss of correction was similar between the two groups for both thoracic (4.1° vs. 3.6°) and lumbar (4.2° vs. 4.6°) curves (P > 0.05). EBL (1972 ml vs. 1530) and operation time (669 min vs. 419 min) were significantly increased in Group 1 than in Group 2 (P < 0.05). No difference was noted for SRS-22 total scores in the last follow-up between the two groups (3.7 vs. 3.8, P > 0.05). In conclusion, as compared to anterior release combined with posterior spinal fusion, posterior-only spinal fusion could yield comparable clinical outcomes for scoliosis associated with Marfan syndrome with lower EBL, and operation time. However, longer follow-up is needed to verify these findings.

We investigated the outcome of posterior decompression and instrumented fusion (PDF) surgery for patients with K-line (-) ossification of the posterior longitudinal ligament (OPLL) of the cervical spine, who may have a poor surgical prognosis. We retrospectively analyzed the outcome of a series of 27 patients who underwent PDF without correction of cervical alignment for K-line (-) OPLL and were followed-up for at least 1 year after surgery. We had performed double-door laminoplasty followed by posterior instrumented fusion without excessive correction of cervical spine alignment. The preoperative Japanese Orthopedic Association (JOA) score for cervical myelopathy was 8.0 points and postoperative JOA score was 11.9 points on average. The mean JOA score recovery rate was 43.6%. The average C2-C7 angle was 2.2° preoperatively and 3.1° postoperatively. The average maximum occupation ratio of OPLL was 56.7%. In conclusion, PDF without correcting cervical alignment for patients with K-line (-) OPLL showed moderate neurological recovery, which was acceptable considering K-line (-) predicts poor surgical outcomes. Thus, PDF is a surgical option for such patients with OPLL. Copyright © 2016 Elsevier Ltd. All rights reserved.

To determine the role of night orthosis use after surgical correction of Dupuytren contracture. We searched MEDLINE, EMBASE, CINAHL, AMED, OTSeeker, and CENTRAL for articles published from inception of the databases to August 2015. Assessment was undertaken by 2 independent reviewers (O.A.S. and S.A.). Methodological quality of randomized controlled trials was assessed using the Cochrane risk of bias tool and the Newcastle-Ottawa instrument. Seven studies met the standard for inclusion in this review. A total of 659 patients across these 7 studies were included in the analysis, with follow-up ranging from 3 to 72 months. None of the included studies assessed recurrence. The analysis revealed no significant improvement in range of motion of hand joints for patients who received a static night orthosis after Dupuytren surgery compared with patients without an orthosis. Similarly, no differences were found in patient-reported functional status across the 2 groups. The current literature does not appear to support the use of static night orthosis in addition to hand therapy after surgical correction of Dupuytren contracture. Therapeutic IV.

Limb lengthening by distraction osteogenesis was first described in 1905. The technique did not gain wide acceptance until Gavril Ilizarov identified the physiologic and mechanical factors governing successful regeneration of bone formation. Distraction osteogenesis is a new variation of more traditional orthognathic surgical procedure for the correction of dentofacial deformities. It is most commonly used for the correction of more severe deformities and syndromes of both the maxilla and the mandible and can also be used in children at ages previously untreatable. The basic technique includes surgical fracture of deformed bone, insertion of device, 5-7 days rest, and gradual separation of bony segments by subsequent activation at the rate of 1 mm per day, followed by an 8-12 weeks consolidation phase. This allows surgeons, the lengthening and reshaping of deformed bone. The aim of this paper is to review the principle, technical considerations, applications and limitations of distraction osteogenesis. The application of osteodistraction offers novel solutions for surgical-orthodontic management of developmental anomalies of the craniofacial skeleton as bone may be molded into different shapes along with the soft tissue component gradually thereby resulting in less relapse.

ABSTRACT Objectives The purpose of this first part of a two-part series was to review the literature concerning the indications, contraindications, advantages, disadvantages and surgical techniques of the lateralization and transposition of the inferior alveolar nerve, followed by the placement of an implant in an edentulous atrophic posterior mandible. Material and Methods A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed and PMC database, academic sites and books. The articles were searched from January 1997 to July 2014 and comprised English-language articles that included adult patients between 18 and 80 years old with minimal residual bone above the mandibular canal who had undergone inferior alveolar nerve (IAN) repositioning with a minimum 6 months of follow-up. Results A total of 16 studies were included in this review. Nine were related to IAN transposition, 4 to IAN lateralization and 3 to both transposition and lateralization. Implant treatment results and complications were presented. Conclusions Inferior alveolar nerve lateralization and transposition in combination with the installation of dental implants is sometimes the only possible procedure to help patients to obtain a fixed prosthesis, in edentulous atrophic posterior mandibles. With careful pre-operative surgical and prosthetic planning, imaging, and extremely precise surgical technique, this procedure can be successfully used for implant placement in edentulous posterior mandibular segments.

Objectives: Update on clinical results obtained by the first worldwide facial transplantation teams as well as review of the literature concerning the main surgical, immunological, ethical, and follow-up aspects described on facial transplanted patients. Study design: MEDLINE search of articles published on “face transplantation” until March 2012. Results: Eighteen clinical cases were studied. The mean patient age was 37.5 years, with a higher prevalence of men. Main surgical indication was gunshot injuries (6 patients). All patients had previously undergone multiple conventional surgical reconstructive procedures which had failed. Altogether 8 transplant teams belonging to 4 countries participated. Thirteen partial face transplantations and 5 full face transplantations have been performed. Allografts are varied according to face anatomical components and the amount of skin, muscle, bone, and other tissues included, though all were grafted successfully and remained viable without significant postoperative surgical complications. The patient with the longest follow-up was 5 years. Two patients died 2 and 27 months after transplantation. Conclusions: Clinical experience has demonstrated the feasibility of facial transplantation as a valuable reconstructive option, but it still remains considered as an experimental procedure with unresolved issues to settle down. Results show that from a clinical, technical, and immunological standpoint, facial transplantation has achieved functional, aesthetic, and social rehabilitation in severely facial disfigured patients. Key words:Face transplantation, composite tissue transplantation, face allograft, facial reconstruction, outcomes and complications of face transplantation. PMID:23229268

A Robotic device is a powered, computer controlled manipulator with artificial sensing that can be reprogrammed to move and position tools to carry out a wide range of tasks. Robots and Telemanipulators were first developed by the National Aeronautics and Space Administration (NASA) for use in space exploration. Today's medical robotic systems were the brainchild of the United States Department of Defence's desire to decrease war casualties with the development of 'telerobotic surgery'. The 'master-slave' telemanipulator concept was developed for medical use in the early 1990s where the surgeon's (master) manual movements were transmitted to end-effector (slave) instruments at a remote site. Since then, the field of surgical robotics has undergone massive transformation and the future is even brighter. As expected, any new technique brings with it risks and the possibility of technical difficulties. The person who bears the brunt of complications or benefit from a new invention is the 'Patient'. Anaesthesiologists as always must do their part to be the patient's 'best man' in the perioperative period. We should be prepared for screening and selection of patients in a different perspective keeping in mind the steep learning curves of surgeons, long surgical hours, extreme patient positioning and other previously unknown anaesthetic challenges brought about by the surgical robot. In this article we have tried to track the development of surgical robots and consider the unique anaesthetic issues related to robot assisted surgeries.

The increased use of computed tomography has led to an increasing proportion of lung cancers that are identified when still less than 1 cm in diameter. However, there is no defined treatment strategy for such cases. The aim of this study was to investigate the surgical outcomes of small lung cancers. A total of 143 patients were retrospectively evaluated, who had undergone a complete surgical resection for lung cancer less than 1 cm in diameter between January 1995 and December 2011. The 143 study subjects included 62 male and 81 female patients. The mean age was 64.0 years (43-82 years). The mean tumour size was 0.8 cm (0.3-1.0 cm). Seventy-seven patients (53.8%) underwent lobectomy. Thirty-two patients (22.4%) underwent segmentectomy and 34 patients (23.8%) underwent wedge resection. The 3-, 5- and 10-year survival rates were 95.7, 92.2 and 85.7%, respectively, after resection for sub-centimetre lung cancer. There were no significant differences between sub-lobar resection and lobectomy. However, two patients (1.4%) had recurrent cancer and seven (4.9%) had lymph node metastasis. The selection of the surgical procedure is important and a long-term follow-up is mandatory, because lung cancer of only 1 cm or less can be associated with lymph node metastasis and distant metastatic recurrence.

An 8-year-old female captive reindeer (Rangifer tarandus) (1) was presented for evaluation of bilateral protrusion of the cheeks of 1-month duration. Several members of the herd displayed similar clinical signs. Examination revealed stretching and laxity of the cheek muscles and buccal food impaction. The defect of each cheek was surgically repaired in the field under heavy sedation and local anesthesia in staged procedures; no surgical complications were encountered. The patient recovered uneventfully and long-term prognosis is good. This report describes a surgical treatment for individual animals with cheek laxity and buccal food impaction. PMID:28588329

Prospective multicenter database. To identify factors associated with outcomes from adolescent idiopathic scoliosis (AIS) surgery outcomes and especially poor results. Because AIS is rarely symptomatic during adolescence, excellent surgical results are expected. However, some patients have poor outcomes. This study seeks to identify factors correlating with results and especially those making poor outcomes more likely. Demographic, surgical, and radiographic parameters were compared to 2-year postoperative Scoliosis Research Society (SRS) scores in 477 AIS surgical patients using stepwise linear regression to identify factors predictive of 2-year domain and total scores. Poor postoperative score patients (>2 SD below mean) were compared using t tests to those with better results. The SRS instrument exhibited a strong ceiling effect. Two-year scores showed more improvement with greater curve correction (self-image, pain, and total), and were worse with larger body mass index (pain, mental, total), larger preoperative trunk shift (mental and total), larger preoperative Cobb (self-image), and preoperative symptoms (function). Poor results were more common in those with Lenke 3 curve pattern (pain), less preoperative coronal imbalance, trunk shift and rib prominence (function), preoperative bracing (self-image), and anterior procedures (mental). Poor results also had slightly less average curve correction (50% vs. 60%) and larger curve residuals (31° vs. 23°). Complications, postoperative curve magnitude, and instrumentation type did not significantly contribute to postoperative scores, and no identifiable factors contributed to satisfaction. Curve correction improves patient's self-image whereas pain and poor function before surgery carry over after surgery. Patients with less spinal appearance issues (higher body mass index, Lenke 3 curves) are less happy with their results. Except in surgical patient selection, many of these factors are beyond physician control.

The McGill Pain Questionnaire (MPQ) provides a quantitative profile of 3 major psychologic dimensions of pain: sensory-discriminative, motivational-affective, and cognitive-evaluative. Although the MPQ is frequently used as a pain measurement tool, no studies to date have compared the characteristics of chronic post-surgical pain after different surgical procedures using a quantitative scoring method. Three separate questionnaire surveys were administered to patients who had undergone surgery at different time points between 1990 and 2000. Surgical procedures selected were mastectomy (n = 511 patients), inguinal hernia repair (n = 351 patients), and cardiac surgery via a central chest wound with or without saphenous vein harvesting (n = 1348 patients). A standard questionnaire format with the MPQ was used for each survey. The IASP definition of chronic pain, continuously or intermittently for longer than 3 months, was used with other criteria for pain location. The type of chronic pain was compared between the surgical populations using 3 different analytical methods: the Pain Rating Intensity score using scale values, (PRI-S); the Pain Rating Intensity using weighted rank values multiplied by scale value (PRI-R); and number of words chosen (NWC). The prevalence of chronic pain after mastectomy, inguinal herniorrhaphy, and median sternotomy with or without saphenectomy was 43%, 30%, and 39% respectively. Chronic pain most frequently reported was sensory-discriminative in quality with similar proportions across different surgical sites. Average PRI-S values after mastectomy, hernia repair, sternotomy (without postoperative anginal symptoms), and saphenectomy were 14.06, 13.00, 12.03, and 8.06 respectively. Analysis was conducted on cardiac patients who reported anginal symptoms with chronic post-surgical pain (PRI-S value 14.28). Patients with moderate and severe pain were more likely to choose more than 10 pain descriptors, regardless of the operative site (P < 0.05). The prevalence and characteristics of chronic pain was remarkably similar across different operative groups. This study is the first to quantitatively compare chronic post-surgical pain using similar methodologies in heterogeneous post-surgical populations.

To evaluate the outcome of modified Quad procedure in preteen and teen patients with brachial plexus birth palsy. We have previously demonstrated a significant improvement in shoulder abduction, resulting from the modified Quad procedure in children (mean age 2.5 years; range, 0.5-9 years) with obstetric brachial plexus injury. We describe in this report the outcome of 16 patients (6 girls and 10 boys; 7 preteen and 9 teen) who have undergone the modified Quad procedure for the correction of the shoulder function, specifically abduction. The patients underwent transfer of the latissimus dorsi and teres major muscles, release of contractures of subscapularis pectoralis major and minor, and axillary nerve decompression and neurolysis (the modified Quad procedure). Mean age of these patients at surgery was 13.5 years (range, 10.1-17.9 years). The mean preoperative total Mallet score was 14.8 (range, 10-20), and active abduction was 84° (range, 20°-140°). At a mean follow-up of 1.5 years, the mean postoperative total Mallet score increased to 19.7 (range, 13-25, P < .0001), and the mean active abduction improved to 132° (range, 40°-180°, P < .0003). The modified Quad procedure greatly improves not only the active abduction but also other shoulder functions in preteen and teen patients, as this outcome is the combined result of decompression and neurolysis of the axillary nerve and the release of the contracted internal rotators of the shoulder.

Vision loss in Sturge-Weber syndrome (SWS), a rare congenital disorder, is primarily due to glaucoma. We reviewed the data of all consecutive SWS-associated glaucoma cases in patients who had undergone combined trabeculotomy-trabeculectomy (CTT) at a tertiary glaucoma facility between January 1993 and December 2015. We analyzed the preoperative and postoperative intraocular pressure (IOP), corneal clarity, visual acuity, success rate, need for repeat surgery, and number of topical antiglaucoma medications needed at last follow-up. Twenty-six eyes of 20 patients with SWS (surgical age 0.7-96 months; mean 18.64 ± 29.74 months) had undergone primary CTT. The mean preoperative IOP was 32.76 ± 7.86 mm Hg (range 22-54 mm Hg) with medication (mean 3.11 ± 1.17; range 1-5). At the last follow-up (61-288 months); mean SD 134.73 ± 67.77 months), two eyes had IOP <6 mm Hg. Twenty-four eyes analyzed had an IOP of 13.63 ± 6.11 (mean ± SD; range 9-41) mm Hg. All these had an IOP <15 mm Hg at last follow-up except one, which had an IOP of 41 mm Hg. There was a mean reduction of 54.62% ± 31.33% in IOP from baseline. The antiglaucoma medication score at last follow-up visit was 0-3. No eye achieved predefined complete success or modified complete success. A total of 41.7% (10/24) of eyes attained both qualified and modified qualified success. Eleven eyes needed repeat surgeries. No intraoperative complications were noted. Visual acuity was below 6/60 in four eyes. Combined trabeculotomy-trabeculectomy showed promising results as a treatment for SWS-associated glaucoma in children. Long-term visual and surgical outcomes are encouraging.

Posterior decompression with instrumented fusion (PDF) surgery has been previously reported as a relatively safe surgical procedure for any type of thoracic ossification of the longitudinal ligament (OPLL). However, mid- to long-term outcomes are still unclear. The aim of the present study was to elucidate the mid- to long-term clinical outcome of PDF surgery for thoracic OPLL patients. The present study included 20 patients who had undergone PDF for thoracic OPLL and were followed for at least 5years. Increment change and recovery rate of the Japanese Orthopaedic Association (JOA) score were assessed. Revision surgery during the follow-up period was also recorded. Average JOA scores were 3.5 preoperatively and 7.1 at final follow-up. The average improvement in JOA score was 3.8 points and the average recovery rate was 47.0%. The JOA score showed gradual increase after surgery, and took 9months to reach peak recovery. As for neurological complications, two patients suffered postoperative paralysis, but both recovered without intervention. Six revision surgeries in four patients were related to OPLL. Additional anterior thoracic decompression for remaining ossification at the same level of PDF surgery was performed in one patient. Decompression surgery for deterioration of symptoms of pre-existing cervical OPLL was performed in three patients. One patient had undergone lumbar and cervical PDF surgery for de novo ossification foci of the lumbar and cervical spine. PDF surgery for thoracic OPLL is thus considered a relatively safe and stable surgical procedure considering the mid- to long-term outcomes. Copyright © 2015 Elsevier Ltd. All rights reserved.

The indications, operative findings, and outcomes of vestibular schwannoma microsurgery are controversial when it is performed after stereotactic radiosurgery. To address these issues, the authors reviewed the experience at two academic medical centers. During a 10-year interval, 452 patients with unilateral vestibular schwannomas underwent gamma knife radiosurgery. Thirteen patients (2.9%) underwent delayed microsurgery at a median of 27 months (range 7–72 months) after they had undergone radiosurgery. Six of the 13 patients had undergone one or more microsurgical procedures before they underwent radiosurgery. The indications for surgery were tumor enlargement with stable symptoms in five patients, tumor enlargement with new or increased symptoms in five patients, and increased symptoms without evidence of tumor growth in three patients. Gross-total resection was achieved in seven patients and near-gross-total resection in four patients. The surgery was described as more difficult than that typically performed for schwannoma in eight patients, no different in four patients, and easier in one patient. At the last follow-up evaluation, three patients had normal or near-normal facial function, three patients had moderate facial dysfunction, and seven had facial palsies. Three patients were incapable of caring for themselves, and one patient died of progression of a malignant triton tumor. Failed radiosurgery in cases of vestibular schwannoma was rare. No clear relationship was demonstrated between the use of radiosurgery and the subsequent ease or difficulty of delayed microsurgery. Because some patients have temporary enlargement of their tumor after radiosurgery, the need for surgical resection after radiosurgery should be reviewed with the neurosurgeon who performed the radiosurgery and should be delayed until sustained tumor growth is confirmed. A subtotal tumor resection should be considered for patients who require surgical resection of their tumor after vestibular schwannoma radiosurgery.

The purpose of the study was to evaluate possible differences between genders in amputation incidence, revascularization activity before and survival after amputation. This population-based study was carried out in a well-defined geographical area, where all vascular surgical consultations and reconstructions are performed in one university hospital. All amputations performed in the region during 1990 - 1999 were identified from the hospital central registers. According to patient's identity codes, the Cause of Death Registry of Statistics Finland provided death data. Amputation data were cross-linked with the local vascular registry using identity codes. Women were found to be 8 years older than men (p < 0.0001). Major amputations comprised 73.4% in males and 77.7% in females. The age-standardized amputation incidence among males was 338 and among females 226 (per 10(6) inhabitants/year) (p < 0.001). The most prominent difference was seen in amputations due to trauma, where the age-adjusted major amputation incidence was over three-fold among males compared to females. The proportion of patients who had undergone vascular procedure before amputation was 23% in both genders. Median survival after amputation was 943 days in men and 716 in women (p = 0.01). When the higher age of women was considered, there was no significant difference between the genders. Survival was poorer among diabetics in both genders and the difference was significant in males. The amputation incidence was found to be higher in men compared to women in all etiologic subgroups except malignant tumour. Almost one in 4 patients had undergone vascular surgical reconstruction before amputation in both genders. There was no significant difference between the genders in survival after amputation. Subjects with diabetes had a poorer survival after major amputation than those without diabetes.

Subtalar Coalitions: Does the Morphology of the Subtalar Joint Involvement Influence Outcomes After Coalition Excision?

PubMed

Mahan, Susan T; Prete, Victoria I; Spencer, Samantha A; Kasser, James R; Bixby, Sarah D

Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score). Blinded analysis of the preoperative CT scan findings determined the presence of a standard MF versus a PMST coalition. The perioperative factors and postoperative outcomes between the MF and PMST coalitions were compared. A total of 51 feet (36 patients) were included. The mean follow-up duration was 2.6 years after surgery. Of the 51 feet, 15 (29.4%) had a PMST coalition and 36 (70.6%) had an MF coalition. No difference was found in the UCLA activity score; however, the mean AOFAS scale score was higher for patients with PMST (95.7) than for those with MF (86.5; p = .018). Of the patients with a PMST, none had foot pain limiting their activities at the final clinical follow-up visit. However, in the group with an MF subtalar coalition, 10 (27.8%) had ongoing foot pain limiting activity at the final follow-up visit (p = .024). Compared with MF subtalar tarsal coalitions, patients with PMST coalitions showed significantly improved clinical outcomes after excision. Preoperative identification of the facet morphology can improve patient counseling and expectations after surgery. Copyright © 2017 American College of Foot and Ankle Surgeons.

2017-07-24

The aim of this study was to systematically evaluate the incidence of infective endocarditis (IE) in right ventricle-to-pulmonary artery conduits and valves, comparing bovine jugular vein (BJV) valves with all others. Recent evidence suggests that the incidence of IE is higher in patients with congenital heart disease who have undergone implantation of BJV valves in the pulmonary position compared with other valves. Systematic searches of published research were conducted using electronic databases (MEDLINE, Embase, and CINAHL) and citations cross-referenced current to April 2016. Included studies met the following criteria: patients had undergone right ventricle-to-pulmonary artery conduit or percutaneous pulmonary valve implantation, and investigators reported on the type of conduit or valve implanted, method of intervention (surgery or catheter based), IE incidence, and follow-up time. Fifty studies (Levels of Evidence: 2 to 4) were identified involving 7,063 patients. The median cumulative incidence of IE was higher for BJV compared with other valves (5.4% vs. 1.2%; p < 0.0001) during a median follow-up period of 24.0 and 35.5 months, respectively (p = 0.03). For patients with BJV valves, the incidence of IE was not different between surgical and catheter-based valve implantation (p = 0.83). There was a higher incidence of endocarditis with BJV valves than other types of right ventricle-to-pulmonary artery conduits. There was no difference in the incidence of endocarditis between catheter-based bovine valves and surgically implanted bovine valves, suggesting that the substrate for future infection is related to the tissue rather than the method of implantation.

Introduction: While the effects of increasing body mass index on prostate cancer epidemiology and surgical approach have recently been studied, its effects on surgical outcomes are less clear. We studied the perioperative outcomes of obese (BMI >= 30) men treated with daVinci-assisted laparoscopic radical prostatectomy (DLP) and compared them to those treated with open radical retropubic prostatectomy (RRP) in a contemporary time frame. Method: After Institutional Review Board approval, we used the Mayo Clinic Radical Prostatectomy database to identify patients who had undergone DLP by a single surgeon and those who had undergone open RRP by a single surgeon between December 2002 and March 2005. Baseline demographics, peri- and post-operative courses, and complications were collected by retrospective chart review, and variables from the two cohorts compared using chi-square method and least-squares method of linear regression where appropriate. Results: 59 patients who had DLP and 76 undergoing RRP were available for study. Baseline demographics were not statistically different between the two cohorts. Although DLP had a significantly lower clinical stage than RRP (p=0.02), pathological stage was not statistically different (p=0.10). Transfusion rates, hospital stay, overall complications, and pathological Gleason were also not significantly different, nor were PSA progression, positive margin rate, or continence at 1 year. After bilateral nerve-sparing, erections suitable for intercourse with or without therapy at 1 year was 88.5% (23/26) for DLP and 61.2% (30/49) for RRP (p=0.01). Follow-up time was similar. Conclusion: For obese patients, DLP appears to have similar perioperative, as well as short-term oncologic and functional outcomes when compared to open RRP.

Despite the well-documented safety and effectiveness of laparoscopic colorectal surgery in curative intention, the role of conversion and its impact on short- and long-term outcome after resection of a carcinoma are unclear and continue to give rise to controversial discussion. Within the framework of a prospective, multicenter observational study (Laparoscopic Colorectal Surgery Study Group), into which a total of 5,863 patients from 69 hospitals were recruited over a period of 10 years, a subgroup of all patients who had undergone curative resection was analyzed with regard to the effects of conversion. Of the 1409 patients who had undergone curative resection for colorectal carcinoma, conversion had to be performed in 80 (5.7%) cases for the most diverse reasons. The duration of surgery (median: 183 vs. 241 minutes; P<.001) was significantly longer in the conversion group. Perioperatively, significant disadvantages were noted in converted patients in terms of intraoperative blood loss (median: 243 vs. 573 mL, P<.001), need for perioperative blood transfusion (10.8% vs. 33.8%; P<.001), and resumption of bowel movement (median: after 3 vs. 4 days; P<.001). With regard to postoperative morbidity, significant disadvantages were observed in converted patients, in particular in terms of specific surgical complications, including a higher rate of anastomotic insufficiency (5.0% vs. 13.8%; P=.003) and a higher reoperation rate (4.9% vs. 15.0%; P=.001). In the long term, conversion was associated with lower overall survival, but not with poorer disease-free survival. Significantly higher postoperative morbidity was observed in patients after conversion, in particular in terms of specific surgical complications. In addition, conversion is associated with overall lower survival but not with poorer disease-free survival.

The surgical and non-surgical treatment of localised prostate cancer may be complicated by bladder neck contractures, prostatic urethral stenoses and bulbomembranous urethral strictures. In general, such complications following radical prostatectomy are less extensive, easier to treat and associated with a better outcome and more rapid recovery than the same complications following radiotherapy, high-intensity focussed ultrasound and cryotherapy. Treatment options range from minimally invasive endoscopic procedures to more complex and specialised open surgical reconstruction.In this chapter the surgical management of bladder neck contractures following the treatment of prostate cancer is described together with the management of prostatic urethral stenoses and bulbomembranous urethral strictures, given the difficulty in distinguishing them from one another clinically.

Mucopolysaccharidosis type II (MPS II) is the most frequently occurring MPS in Taiwan, with an incidence of 2.05 per 100,000 live male births, but little is known about clinical characteristics and surgical history in Taiwanese patients. Medical history, demographics, signs and symptoms, and surgical history were analysed in all patients from Taiwanese centres in the Hunter Outcome Survey (HOS; NCT 03292887), a global, multicentre registry that collects real-world data on patients with MPS II. As of January 2016, 61 male Taiwanese patients were enrolled; 49% (24/49) had received at least one infusion of idursulfase. Median (10th, 90th percentiles) ages at signs and symptom onset and at diagnosis were 2.5 (0.2, 5.5) years (n = 55) and 3.5 (1.2, 11.9) years (n = 56), respectively. Hernia, facial features consistent with MPS II and claw hands were the earliest presenting signs and symptoms (median ages of 3.2 [0.4, 12.0] years, 4.3 [1.1, 12.0] years and 4.7 [2.5, 12.2] years [n = 45, 53 and 50], respectively). More than 75% of patients had undergone a surgical procedure, most commonly hernia repair (57% of patients). Median age at first surgery for hernia repair was 4.2 (0.5, 9.8) years (n = 35). Almost one-third (31.1%) of patients had at least one surgical procedure before diagnosis, and of the 20 procedures before diagnosis, 16 were hernia repair. This information from patients in HOS highlights the importance of both medical and surgical history in diagnosing MPS II in Taiwanese patients.

To compare the predictive ability of primary and secondary Gleason pattern for positive surgical margins in patients with clinically localized prostate cancer and a preoperative Gleason score ≤ 6. A retrospective analysis of the medical records of patients undergone a radical prostatectomy between January 2005 and October 2010 was conducted. Patients' age, prostate volume, preoperative PSA, biopsy Gleason score, the 1st and 2nd Gleason pattern were entered a univariate and multivariate analysis. The 1st and 2nd pattern were tested for their ability to predict positive surgical margins using receiver operating characteristic curves. Positive surgical margins were noticed in 56 cases (38.1%) out of 147 studied patients. The 2nd pattern was significantly greater in those with positive surgical margins while the 1st pattern was not significantly different between the 2 groups of patients. ROC analysis revealed that area under the curve was 0.53 (p=0.538) for the 1st pattern and 0.60 (p=0.048) for the 2nd pattern. Concerning the cases with PSA <10 ng/ml, it was also found that only the 2nd pattern had a predictive ability (p=0.050). When multiple logistic regression analysis was conducted it was found that the 2nd pattern was the only independent predictor. The second Gleason pattern was found to be of higher value than the 1st one for the prediction of positive surgical margins in patients with preoperative Gleason score ≤ 6 and this should be considered especially when a neurovascular bundle sparing radical prostatectomy is planned, in order not to harm the oncological outcome.

Pelvic fractures requiring surgical fixation are rare injuries but present a great societal impact in terms of disability, as well as economic resources. In the literature, there is no description of these costs. Main aim of this study is to describe the direct and indirect costs of these fractures. Secondary aims were to test if the type of fracture (pelvic ring injury or acetabular fracture) influences these costs (hospitalization, consultation, medication, physiotherapy sessions, job absenteeism). We performed a retrospective study on patients with surgically treated acetabular fractures or pelvic ring injuries. Medical records were reviewed in terms of demographic data, follow-up, diagnosis (according to Letournel and Tile classifications for acetabular and pelvic fractures, respectively) and type of surgical treatment. Patients were interviewed about hospitalization length, consultations after discharge, medications, physiotherapy sessions and absenteeism. The study comprised 203 patients, with a mean age of 49.1 ± 15.6 years, who had undergone surgery for an acetabular fracture or pelvic ring injury. The median treatment costs were 29.425 Euros per patient. Sixty percent of the total costs were attributed to health-related work absence. Median costs (in Euros) were 2.767 for hospitalization from trauma to definitive surgery, 4.530 for surgery, 3.018 for hospitalization in the surgical unit, 1.693 for hospitalization in the rehabilitation unit, 1.920 for physiotherapy after discharge and 402 for consultations after discharge. Total costs for treating pelvic ring injuries were higher than for acetabular fractures, mainly due to the significant higher costs of pelvic injuries regarding hospitalization from trauma to definitive surgery (p < 0.001) and hospitalization in the surgical unit (p = 0.008). Pelvic fractures are associated with both high direct costs and substantial productivity loss.

Little is known about the perioperative complication rates of the surgical management of midshaft clavicle nonunions. The purpose of the current study was to report on the perioperative complication rates after surgical management of nonunions and to compare them with complication rates of acute fractures using a population cohort. The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify patients who had undergone open reduction-internal fixation of midshaft clavicle fractures between 2007 and 2013. Patients were stratified by operative indication: acute fracture or nonunion. Patient characteristics and 30-day complication rates were compared between the 2 groups using univariate and multivariate analyses. A total of 1215 patients were included in our analysis. Of these, 1006 (82.8%) were acute midshaft clavicle fractures and 209 (17.2%) were midshaft nonunions. Patients undergoing surgical fixation for nonunion had a higher rate of total complications compared with the acute fracture group (5.26% vs. 2.28%; P = .034). On multivariate analysis, patients with a nonunion were at a >2-fold increased risk of any postsurgical complication (odds ratio, 2.29 [95% confidence interval, 1.05-5.00]; P = .037) and >3-fold increased risk of a wound complication (odds ratio, 3.22 [95% confidence interval, 1.02-10.20]; P = .046) compared with acute fractures. On the basis of these findings, patients undergoing surgical fixation for a midshaft clavicle nonunion are at an increased risk of short-term complications compared with acute fractures. This study provides additional information to consider in making management decisions for these common injuries. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

2012-07-01

Study Type - Diagnostic (exploratory cohort) Level of Evidence 2b What's known on the subject? and What does the study add? The widespread use of serum PSA testing followed by TRUS-guided biopsy have resulted in profound prostate cancer stage migration with many patients presenting with focal rather than multifocal disease. There is increasing interest in the use of focal rather than whole-gland treatment. However, current biopsy schemes may still miss cancer or, even when cancer is identified, its extent or grade might not be accurately characterized. In order for focal therapy to be effective, the area of highest tumour volume and/or grade needs to localized accurately. The aim of this study was to assess how well biopsy, as currently performed, locates the focus of highest prostate cancer volume and/or grade. To evaluate the ability of transrectal ultrasonography (TRUS)-guided extended core biopsy to identify the dominant tumour accurately in men with early stage prostate cancer. Patients with early stage, low-risk prostate cancer who subsequently underwent radical prostatectomy (RP) and had complete surgical specimens were identified. Re-review was performed by a single uropathologist using ImageJ software to identify tumour location, dominant grade (DG) and dominant volume (DV). Pathology findings were then compared with biopsy results. A total of 51 men with early stage, low-risk prostate cancer, who had undergone RP, had complete specimens for review and a median of 15 biopsy cores taken for diagnosis and grading. Sixteen men had a single diagnostic biopsy, 21 had one repeat biopsy, and 14 had two or more repeat biopsies. Compared with surgical findings, biopsy correctly identified the sextant with the largest tumour volume in 55% (95% CI 0.5-0.6) of specimens and the highest grade in 37% (95 CI 0.3-0.5). No demographic or clinical factors were significantly associated with identification of DG. Interval between last biopsy and RP, total tissue length taken and total length of tumour identified were significantly associated with correct identification of DV. Our findings show that TRUS-guided biopsy detects and localizes DV better than it does DG. Even with an extended scheme, TRUS-guided biopsy does not reliably identify dominant cancer location in this low-risk cohort of men with early stage prostate cancer. TRUS-guided biopsy may perform better in similar men with low stage, but higher volume disease. © 2011 BJU INTERNATIONAL.

Determination of surgical variables for a brain shift correction pipeline using an Android application

Brain shift describes the deformation that the brain undergoes from mechanical and physiological effects typically during a neurosurgical or neurointerventional procedure. With respect to image guidance techniques, brain shift has been shown to compromise the fidelity of these approaches. In recent work, a computational pipeline has been developed to predict "brain shift" based on preoperatively determined surgical variables (such as head orientation), and subsequently correct preoperative images to more closely match the intraoperative state of the brain. However, a clinical workflow difficulty in the execution of this pipeline has been acquiring the surgical variables by the neurosurgeon prior to surgery. In order to simplify and expedite this process, an Android, Java-based application designed for tablets was developed to provide the neurosurgeon with the ability to orient 3D computer graphic models of the patient's head, determine expected location and size of the craniotomy, and provide the trajectory into the tumor. These variables are exported for use as inputs for the biomechanical models of the preoperative computing phase for the brain shift correction pipeline. The accuracy of the application's exported data was determined by comparing it to data acquired from the physical execution of the surgeon's plan on a phantom head. Results indicated good overlap of craniotomy predictions, craniotomy centroid locations, and estimates of patient's head orientation with respect to gravity. However, improvements in the app interface and mock surgical setup are needed to minimize error.

We present a novel approach using distributed source coding for image authentication. The key idea is to provide a Slepian-Wolf encoded quantized image projection as authentication data. This version can be correctly decoded with the help of an authentic image as side information. Distributed source coding provides the desired robustness against legitimate variations while detecting illegitimate modification. The decoder incorporating expectation maximization algorithms can authenticate images which have undergone contrast, brightness, and affine warping adjustments. Our authentication system also offers tampering localization by using the sum-product algorithm.

Kordahi, Anthony M; Hoppe, Ian C; Lee, Edward S

2015-01-01

Reduction mammoplasty is an often-performed procedure by plastic surgeons and increasingly by general surgeons. The question has been posed in both general surgical literature and plastic surgical literature as to whether this procedure should remain the domain of surgical specialists. Some general surgeons are trained in breast reductions, whereas all plastic surgeons receive training in this procedure. The National Surgical Quality Improvement Project provides a unique opportunity to compare the 2 surgical specialties in an unbiased manner in terms of preoperative comorbidities and 30-day postoperative complications. The National Surgical Quality Improvement Project database was queried for the years 2005-2012. Patients were identified as having undergone a reduction mammoplasty by Current Procedural Terminology codes. RESULTS were refined to include only females with an International Classification of Diseases, Ninth Revision, code of 611.1 (hypertrophy of breasts). Information was collected regarding age, surgical specialty performing procedure, body mass index, and other preoperative variables. The outcomes utilized were presence of superficial surgical site infection, presence of deep surgical site infection, presence of wound dehiscence, postoperative respiratory compromise, pulmonary embolism, deep vein thrombosis, perioperative transfusion, operative time, reintubation, reoperation, and length of hospital stay. During this time period, there were 6239 reduction mammaplasties performed within the National Surgical Quality Improvement Project database: 339 by general surgery and 5900 by plastic surgery. No statistical differences were detected between the 2 groups with regard to superficial wound infections, deep wound infections, organ space infections, or wound dehiscence. There were no significant differences noted between within groups with regard to systemic postoperative complications. Patients undergoing a procedure by general surgery were more likely to experience a failure of skin flaps, necessitating a return to the operative room (P < .05). Operative time was longer in procedures performed by general surgery (P < .05). Several important differences appear to exist between reduction mammaplasties performed by general surgery and plastic surgery. A focused training in reduction mammoplasty appears to be beneficial to the patient. The limitations of this study include a lack of long-term follow-up with regard to aesthetic outcome, nipple malposition, nipple sensation, and late wound sequelae.

OBJECTIVE Given the increasing prevalence of obesity, more patients with a high body mass index (BMI) will require surgical treatment for degenerative spinal disease. In previous investigations of lumbar spine pathology, obesity has been associated with worsened postoperative outcomes and increased costs. However, few studies have examined the association between BMI and postoperative outcomes following anterior cervical discectomy and fusion (ACDF) procedures. Thus, the purpose of this study was to compare surgical outcomes, postoperative narcotics consumption, complications, and hospital costs among BMI stratifications for patients who have undergone primary 1- to 2-level ACDF procedures. METHODS The authors retrospectively reviewed a prospectively maintained surgical database of patients who had undergone primary 1- to 2-level ACDF for degenerative spinal pathology between 2008 and 2015. Patients were stratified by BMI as follows: normal weight (< 25.0 kg/m 2 ), overweight (25.0-29.9 kg/m 2 ), obese I (30.0-34.9 kg/m 2 ), or obese II-III (≥ 35.0 kg/m 2 ). Differences in patient demographics and preoperative characteristics were compared across the BMI cohorts using 1-way ANOVA or chi-square analysis. Multivariate linear or Poisson regression with robust error variance was used to determine the presence of an association between BMI category and narcotics utilization, improvement in visual analog scale (VAS) scores, incidence of complications, arthrodesis rates, reoperation rates, and hospital costs. Regression analyses were controlled for preoperative demographic and procedural characteristics. RESULTS Two hundred seventy-seven patients were included in the analysis, of whom 20.9% (n = 58) were normal weight, 37.5% (n = 104) were overweight, 24.9% (n = 69) were obese I, and 16.6% (n = 46) were obese II-III. A higher BMI was associated with an older age (p = 0.049) and increased comorbidity burden (p = 0.001). No differences in sex, smoking status, insurance type, diagnosis, presence of neuropathy, or preoperative VAS pain scores were found among the BMI cohorts (p > 0.05). No significant differences were found among these cohorts as regards operative time, intraoperative blood loss, length of hospital stay, and number of operative levels (p > 0.05). Additionally, no significant differences in postoperative narcotics consumption, VAS score improvement, complication rates, arthrodesis rates, reoperation rates, or total direct costs existed across BMI stratifications (p > 0.05). CONCLUSIONS Patients with a higher BMI demonstrated surgical outcomes, narcotics consumption, and hospital costs comparable to those of patients with a lower BMI. Thus, ACDF procedures are both safe and effective for all patients across the entire BMI spectrum. Patients should be counseled to expect similar rates of postoperative complications and eventual clinical improvement regardless of their BMI.

To investigate the surgical results of an ear cartilage graft and supplemental procedures for correcting lower lid retraction combined with entropion in anophthalmic patients. We reviewed retrospectively the medical records of 7 anophthalmic patients with lower lid retraction and entropion, who received a posterior lamellar ear cartilage graft and one or both of lateral tarsal strip or eyelash-everting procedure between March 1998 and March 2003. Preoperative and postoperative lid and socket statuses were also investigated. Ear cartilage grafts were performed in all 7 patients, lateral tarsal strips in 6, and eyelash-everting procedures in 5. Postoperative follow-up durations ranged from 4 to 28 months (average 12.6 months). Retractions were corrected during follow-up in all patients. There were no cases of entropion immediately after surgery. However, the eyelashes of the lower lid returned to an upright position in 4 patients, but not so severe as to touch the ocular prosthesis, and thus did not require surgical correction during follow up. Lower lid retraction combined with entropion in anophthalmic patients can be corrected effectively using an ear cartilage graft with selective, supplemental procedures.

Pectus carinatum (PC) is a chest deformity caused by a disproportionate growth of the costal cartilages compared to the bony thoracic skeleton, pulling the sternum towards, which leads to its protrusion. There has been a growing interest on using the 'reversed Nuss' technique as a minimally invasive procedure for PC surgical correction. A corrective bar is introduced between the skin and the thoracic cage and positioned on top of the sternum highest protrusion area for continuous pressure. Then, it is fixed to the ribs and kept implanted for about 2-3 years. The purpose of this work was to (a) assess the stresses distribution on the thoracic cage that arise from the procedure, and (b) investigate the impact of different positioning of the corrective bar along the sternum. The higher stresses were generated on the 4th, 5th and 6th ribs backend, supporting the hypothesis of pectus deformities correction-induced scoliosis. The different bar positioning originated different stresses on the ribs' backend. The bar position that led to lower stresses generated on the ribs backend was the one that also led to the smallest sternum displacement. However, this may be preferred, as the risk of induced scoliosis is lowered.

To investigate the trends in refractive correction in Japanese Ground Self-Defense Forces' (JGSDF) soldiers. A questionnaire was distributed to 519 soldiers of the Camp Funaoka in the northeastern region. Five hundred and sixteen subjects (99.4%) responded. In total, 246 soldiers (47.7%) wore spectacles or contact lenses. Among the contact lens wearers, 52 had experienced problems previously and 35 reported problems that occurred during military exercises. With regard to military exercises, 66.9% and 63.5% of the spectacle or disposable soft contact lens-users reported inconvenience. Among contact lens users, 33.1% reported that they changed to new sterilized contact lenses only occasionally and 61.9% did not change their contact lenses at all during exercises. During disaster-relief work, subjects worried 'very' (21.5%) or 'somewhat' (46.9%) about problems associated with their spectacles or contact lenses. Twenty-four had undergone refractive surgery (4.9%). About one-half of the JGSDF soldiers surveyed required refractive correction. Attention to convenient and safe refractive correction in the military is warranted.

To discuss the pre-surgical orthodontic treatment of skeletal class II patients with gingiva smile corrected by AMSO. We analyzed the clinical features of 20 skeletal class II patients treated by AMSO combined with Orthodontic treatment and evaluated the effects of AMSO by means of cephalometric analysis. After the AMSO treatment, ANB angle, the height of anterior maxilla, the protrusion of the upper anterior teeth, and the of A point had reduced significantly (P < 0.05). After AMSO, the appearance of patients had been improved markedly. AMSO can correct the protrusion of the maxilla and gingival smie efficiently. The anchorage of molars should be controlled carefully. The anterior part of the upper arch should be expended orthodontically to make arch relationship. Extract the upper bicuspid half a year before the surgery was recommended. When necessary, genioplasty could be performed.

Surgical correction of pectus excavatum and carinatum.

1980-01-01

This paper contains an analysis of the long-term results in 85 patients who had pectus excavatum or carinatum deformities repaired at the North Middlesex Hospital between 1951 and 1977. Seventy-seven patients had operations for correction of pectus excavatum and eight for pectus carinatum. A variety of surgical techniques was used. In the excavatum deformities the best results were obtained by the extensive resection of all deformed cartilages, the correction of the sternal deformity by a simple transverse wedge osteotomy, and by stabilising the chest with a stainless steel plate. For pectus carinatum, the involved cartilages were resected and an osteotomy of the sternum was performed. We preferred in most cases to stabilise the chest wall with a metal strut in this deformity as well. The best cosmetic results were achieved by the use of a stainless steel plate passed beneath the sternum and left for not more than six months. PMID:7444843

2016-05-01

Development of dural arteriovenous fistula (dAVF) with cortical venous drainage at the site of previous craniotomy is a rare manifestation of nontraumatic subarachnoid hemorrhage (SAH). The authors present a case of postcraniotomy dAVF formation and discuss plausible underlying mechanisms of fistula formation and treatment options as well as review the literature. A 62-year-old man, who had undergone craniotomy 2 decades previously, presented with SAH. Workup revealed a low-flow dAVF with leptomeningeal venous drainage at the posterior margin of the craniotomy. Surgical resection of fistula was undertaken that resulted in cure. Spontaneous SAH in patients with a previous history of an intracranial procedure (e.g., craniotomy, ventriculostomy) should prompt detailed imaging evaluation. In the absence of vascular disease, meticulous review of the angiogram must be undertaken to rule out dAVF at the procedure site and it should be treated definitively. Copyright © 2016 Elsevier Inc.

Ethical challenges with awake craniotomy for tumor.

PubMed

Kirsch, Brandon; Bernstein, Mark

2012-01-01

Awake brain surgery is useful for the treatment of a number of conditions such as epilepsy and brain tumor, as well as in functional neurosurgery. Several studies have been published regarding clinical results and outcomes of patients who have undergone awake craniotomy but few have dealt with related ethical issues. The authors undertake to explore broadly the ethical issues surrounding awake brain surgery for tumor resection to encourage further consideration and discussion. Based on a review of the literature related to awake craniotomy and in part from the personal experience of the senior author, we conducted an assessment of the ethical issues associated with awake brain tumor surgery. The major ethical issues identified relate to: (1) lack of data; (2) utilization; (3) conflict of interest; (4) informed consent; (5) surgical innovation; and (6) surgical training. The authors respectfully suggest that the selection of patients for awake craniotomy needs to be monitored according to more consistent, objective standards in order to avoid conflicts of interest and potential harm to patients.

Background Nipple-sparing mastectomy (NSM), understood as an oncologically valid procedure, is relatively new, and is an evolution of traditional mastectomy, particularly in relation to breast-conserving surgery. The anterior perforating branches are responsible for the cutaneous vascularization of the breast skin, and their preservation is a fundamental step to avoid possible postoperative necrosis. Therefore, evaluating the potential complications of cancer-related reconstructive surgical procedures such as NSM, both the distance of the tumoral lesion from the skin and the surgical incision site should be carefully considered. The preferred site of incision corresponds to the inframammary fold or possibly the periareolar area. Methods We retrospectively reviewed 113 patients who underwent NSM from January 2005 to October 2012 to evaluate skin complications. The anatomical study was performed by magnetic resonance imaging of the breast. Results Only one of the 113 women who had undergone a NSM procedure had total necrosis (0.9%) and six patients had partial necrosis (5.8%) of the nipple-areola complex. PMID:26203275

Thoracic sympathectomy for hyperhidrosis: from surgical indications to clinical results

PubMed Central

Araújo, José Augusto

2017-01-01

Sympathectomy and its variations have been performed in thoracic surgery for more than 100 years. However, its indications have undergone profound modifications in this period. Likewise, since then the surgical technique has also evolved dramatically up to the minimally invasive techniques worldwide accessible in present days. Currently, primary hyperhidrosis is, by far, the main indication for thoracic sympathectomy and this procedure is usually carried out thoracoscopically with excellent results. However, until today, hyperhidrosis is a part of thoracic surgery still surrounded by controversy, persisting as an open field over which some confusion still resides regarding its pathophysiology, terms definitions and operative approaches. The aim of this article is to provide a wide but easily comprehensible review of the theme, discussing and clarifying the major concepts with respect to its clinical presentation, all the presently available treatment options and strategies with their potential benefits and risks, the adequate patient selection for sympathectomy, as well as the postoperative clinical results.

Lap-Protector, which is an abdominal wall sealing device, is usually used for wound protection from implantation of malignant cells or pyogenic fluid. A circular stapler is a common easy-to-use device for anastomosis of the digestive tract. We report the case of an infected pancreatic pseudocyst which was treated by surgical procedure using these useful devices. A 69-year-old man was followed up in our hospital after severe acute pancreatitis. He had undergone drainage surgeries twice for intractable pancreatic abscess followed by severe acute pancreatitis. He was admitted to our hospital complaining of loss of appetite, hiccups, and high fever. Computed tomography of the abdomen revealed an infected pancreatic pseudocyst which compressed the gastric wall. Internal drainage into the stomach was performed using Lap-Protector and circular stapler. The patient recovered uneventfully. Recently many endoscopic or laparoscopic procedures in cystogastrostomy are reported; however, a conventional open surgical approach is also important. This easy method may be useful for operative cystogastrostomy. PMID:20805947

Down's syndrome is associated with poor Eustachian tube function, and an increased incidence of cholesteatoma. The only previously published case series suggests that 'canal wall preserving' procedures are only rarely suitable for the management of cholesteatoma in this population. We conducted a retrospective review of the hospital's clinical records database to identify patients with Down's syndrome and cholesteatoma. These patients' notes were then reviewed. We identified nine patients with Down's syndrome who had undergone surgical management of cholesteatoma over a twelve year period. Three patients had bilateral disease, meaning twelve ears were treated. Seven ears were initially treated with 'canal wall down' procedures. Four out of five of the remaining ears were successfully treated using 'canal wall preservation' or 'canal wall reconstruction', with one ear requiring subsequent conversion to a 'canal wall down' approach. Canal wall preservation/reconstruction is feasible in patients with Down's syndrome, even when cholesteatoma extends into the mastoid. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Thoracic sympathectomy for hyperhidrosis: from surgical indications to clinical results.

PubMed

Vannucci, Fernando; Araújo, José Augusto

2017-04-01

Sympathectomy and its variations have been performed in thoracic surgery for more than 100 years. However, its indications have undergone profound modifications in this period. Likewise, since then the surgical technique has also evolved dramatically up to the minimally invasive techniques worldwide accessible in present days. Currently, primary hyperhidrosis is, by far, the main indication for thoracic sympathectomy and this procedure is usually carried out thoracoscopically with excellent results. However, until today, hyperhidrosis is a part of thoracic surgery still surrounded by controversy, persisting as an open field over which some confusion still resides regarding its pathophysiology, terms definitions and operative approaches. The aim of this article is to provide a wide but easily comprehensible review of the theme, discussing and clarifying the major concepts with respect to its clinical presentation, all the presently available treatment options and strategies with their potential benefits and risks, the adequate patient selection for sympathectomy, as well as the postoperative clinical results.

This article presents the results of endoscopic treatment for recurrent postcorrosive esophageal stenosis with a tube-stent developed at our institution. The tube-stent was implanted in 5 children with corrosive esophageal injury at the age of 2 to 8.5 years after 7 to 64 dilatation sessions during 5 to 118 months. In total, 13 tube-stents were implanted. One patient had undergone 9 procedures during 2.5 years and the tube-stent remained in place for 14 to 250 days. This patient was tube-stent-dependent due to the lack of any possibility of surgical reconstruction. Two patients had the tube-stent removed after 150 to 205 days and they remain free from esophageal restenosis. One patient did not tolerate the tube-stent, evacuated it after 1 day and was referred for surgical esophagus replacement. One patient is currently still being treated with the tube-stent. Tube-stent was well tolerated and it may be effective in children with recurrent critical postcorrosive esophageal stenosis.

A 74-year-old male had undergone laparoscopic abdominoperineal resection for lower rectal cancer in July 2009. The pathological diagnosis was T2, N0, M0, pStage I (TNM 7th). Because of pathological venous invasion, adjuvant chemotherapy with Tegafur-uracil(UFT)plus Leucovorin for a year was performed. A CT examination revealed slowly growing peripheral right internal iliaclymph node. PET-CT demonstrated a 20mm right lateral lymph node(LLN)metastasis without other distant metastases. On diagnosis of solitary LLN metastasis of rectal cancer, the patient underwent surgical lymph node resection in September 2014. The pathological diagnosis was lymph node metastasis from rectal cancer. Subsequently, the patient received mFOLFOX6 adjuvant chemotherapy for 6 months. The patient remains alive without any recurrence 31 months after the second surgical treatment. lt is important to consider that LLN metastasis of Stage I rectal cancer might still occur a long time after the curative operation.

Computer simulations to compare the correction capabilities of different pedicle screws in adolescent idiopathic scoliosis (AIS) instrumentations. To compare the correction and resulting bone-screw forces associated with different pedicle screws in scoliosis instrumentations. Pedicle screw fixation is widely used in surgical instrumentation for spinal deformity treatment. Screw design, correction philosophies, and surgical techniques are constantly evolving to achieve better control of the vertebrae and correction of the spinal deformity. Yet, there remains a lack of biomechanical studies that quantify the effects and advantages of different screw designs in terms of correction kinematics. The correction capabilities of fixed-angle, multiaxial, uniaxial, and saddle axial screws were kinematically analyzed, simulated, and compared. These simulations were based on the screw patterns and correction techniques proposed by 2 experienced surgeons for 2 AIS cases. Additional instrumentations were assessed to compare the correction and resulting bone-screw forces associated with each type of screw. The fixed-angle, uniaxial and saddle axial screws had similar kinematic behavior and performed better than multiaxial screws in the coronal and transverse planes (8% and 30% greater simulated corrections, respectively). Uniaxial and multiaxial screws were less effective than fixed-angle and saddle axial screws in transmitting compression/distraction to the anterior spine because of their sagittal plane mobility between the screw head and shank. Only the saddle axial screws allow vertebra angle in the sagittal plane to be independently adjusted. Pedicle screws of different designs performed differently for deformity corrections or for compensating screw placement variations in different anatomic planes. For a given AIS case, screw types should be determined based on the particular instrumentation objectives, the deformity's stiffness and characteristics so as to make the best of the screw designs.

Growth impairment in infants with unrestrictive ventricular septal defects (VSD) is common, and normalisation of growth has been reported after surgical correction. Literature is inconsistent about growth velocity after surgery in term and preterm infants. We aimed to establish the pattern of catch-up growth in term and preterm infants submitted to VSD surgical correction before 1 year of age. Fifty-two infants (41 term, 11 preterm) were studied. Anthropometric data at birth, surgery and 3, 6, 12 and 24 months after surgery were collected retrospectively. Statistic analyses were performed in SPSS® version 21. At the time of surgery, growth was severely impaired in term and preterm infants. Term infants underwent a period of fast growth within the first 6 months after surgery, achieving posteriorly a normal growth pattern, as both weight and height were not significantly different from the reference population at 24 months after surgery. Preterms caught-up later than term infants but with a significant weight gain within 3 months after surgery. Early surgical repair of VSD leads to a significant acceleration of growth within 3 to 6 months after surgery, for both groups. • Growth impairment in infants with unrestrictive ventricular septal defects is well documented in literature. • Surgical correction in the first months of life is the current option for most ventricular septal defects, leading to a more favourable growth pattern. • Rapid growth during infancy may be associated with the development of insulin resistance, metabolic syndrome, obesity and cardiovascular disease later in life. What is New: • Literature is inconsistent about catch-up growth velocities after ventricular correction for term infants. • Preterm infants have never been enrolled in previous studies that aimed to establish a pattern of growth after surgery. • This group of children, who underwent a rapid post-surgery catch-up growth that follows a period of failure to thrive, may be at a higher risk of insulin resistance, metabolic syndrome, obesity and cardiovascular disease.

The aim of this study was to review recent literature on mini-invasive surgical technique for the treatment of female stress urinary incontinence (SUI). Surgical aspects, intraoperative and perioperative complications and objective and subjective outcomes were analyzed and compared. The PubMed databank from 2000 to February 2007 was searched for original prospective and randomized studies in English, on surgical treatment of female SUI, which avoided a laparotomic access to the female pelvis. Studies had to investigate at least 40 women with a minimum follow-up of 12 months. A total of 38 prospective studies were found: 27 of them were on mid-urethral slings; 8 assessed urethral injections; and 3 radiofrequency treatment. Fifteen studies were randomized. Follow-ups ranged from 12 to 60 months, except for sexual function which had a 6-month follow-up. Ten out of 38 studies assessed patients who did not refer pelvic organ prolapse or detrusor overactivity and had not undergone any previous anti-incontinence procedure. Mid-urethral slings showed good outcomes and are safe and brief to perform and have a relatively short learning curve. Urethral injections showed discouraging results, as they have poor outcomes and repetitive treatments are frequently necessary. Injections can be used in women with contraindications to major surgical procedures, with intrinsic sphincter deficiency as the main cause of incontinence. Radiofrequency showed worse results than mid-urethral slings and is a valuable choice in women who refuse more invasive procedures. The development of studies with longer follow-ups on mini-invasive surgical techniques are encouraged.

Little, Andrew S.; Shetter, Andrew G.; Shetter, Mary E.

2009-06-01

Purpose: To evaluate the clinical outcome of patients with surgically refractory trigeminal neuralgia (TN) treated with rescue gamma knife radiosurgery (GKRS). Methods and Materials: Seventy-nine patients with typical TN received salvage GKRS between 1997 and 2002 at the Barrow Neurological Institute (BNI). All patients had recurrent pain following at least one prior surgical intervention. Prior surgical interventions included percutaneous destructive procedures, microvascular decompression (MVD), or GKRS. Thirty-one (39%) had undergone at least two prior procedures. The most common salvage dose was 80 Gy, although 40-50 Gy was typical in patients who had received prior radiosurgery. Pain outcome was assessed usingmore » the BNI Pain Intensity Score, and quality of life was assessed using the Brief Pain Inventory. Results: Median follow-up after salvage GKRS was 5.3 years. Actuarial analysis demonstrated that at 5 years, 20% of patients were pain-free and 50% had pain relief. Pain recurred in patients who had an initial response to GKRS at a median of 1.1 years. Twenty-eight (41%) required a subsequent surgical procedure for recurrence. A multivariate Cox proportional hazards model suggested that the strongest predictor of GKRS failure was a history of prior MVD (p=0.029). There were no instances of serious morbidity or mortality. Ten percent of patients developed worsening facial numbness and 8% described their numbness as 'very bothersome.' Conclusions: GKRS salvage for refractory TN is well tolerated and results in long-term pain relief in approximately half the patients treated. Clinicians may reconsider using GKRS to salvage patients who have failed prior MVD.« less

The purpose of this cross-sectional study is to examine the relationship between surgical treatments for sleep-disordered breathing (SDB) and composite measure of surgical complications in a nationally representative sample of hospital discharges among U.S. adults. We performed secondary analyses of 33,679 hospital discharges from the 2002-2012 Nationwide Inpatient Sample that corresponded to U.S. adults (≥18 years) who were free of head-and-neck neoplasms, were diagnosed with SDB and had undergone at least one of seven procedures. Multivariate logistic regression models were constructed to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI), controlling for age, sex, race/ethnicity, obstructive sleep apnea (OSA) and obesity diagnoses. Positive associations were found between composite measure of surgical complications and specific procedures: palatal procedure (aOR = 12.69, 95% CI: 11.91,13.53), nasal surgery (aOR = 6.47, 95% CI: 5.99,6.99), transoral robotic assist (aOR = 5.06, 95% CI: 4.34-5.88), tongue base/hypopharynx (aOR = 4.24, 95% CI: 3.88,4.62), maxillomandibular advancement (MMA) (aOR = 3.24, 95% CI: 2.74,3.84), supraglottoplasty (aOR = 2.75, 95% CI: 1.81,4.19). By contrast, a negative association was found between composite measures of surgical complications and tracheostomy (aOR = 0.033, 95% CI: 0.031,0.035). In conclusion, most procedures for SDB, except tracheostomy, were positively associated with complications, whereby palatal procedures exhibited the strongest and supraglottoplasty exhibited the weakest association.

Spinal instrumentation and fusion for the treatment of scoliosis is primarily a mechanical intervention to correct the deformity and halt further progression. While implant-related complications remain a concern, little is known about the magnitudes of the forces applied to the spine during surgery, which may affect post-surgical outcomes. In this study, the compressive forces applied to each spinal segment during anterior instrumentation were measured in a series of patients with Adolescent Idiopathic Scoliosis. A force transducer was designed and retrofit to a routinely used surgical tool, and compressive forces applied to each segment during surgery were measured for 15 scoliosis patients. Cobb angle correction achieved by each force was measured on intra-operative fluoroscope images. Relative changes in orientation of the screw within the vertebra were also measured to detect intra-operative screw plough. Intra-operative forces were measured for a total of 95 spinal segments. The mean applied compressive force was 540N (SD 230N, range 88N-1019N). There was a clear trend for higher forces to be applied at segments toward the apex of the scoliosis. Fluoroscopic evidence of screw plough was detected at 10 segments (10.5%). The magnitude of forces applied during anterior scoliosis correction vary over a broad range. These forces do reach magnitudes capable of causing intra-operative vertebral body screw plough. Surgeons should be aware there is a risk for tissue overload during correction, however the clinical implications of intra-operative screw plough remain unclear. The dataset presented here is valuable for providing realistic input parameters for in silico surgical simulations. Copyright © 2016 Elsevier Ltd. All rights reserved.

2017-06-01

Dynamic brace compression is a novel treatment for patients with pectus carinatum. The dynamic compression system contains a device to measure the flexibility of the thoracic wall and regulate the pressure of the brace. Patients referred to our pediatric surgical center were screened for treatment with the dynamic compression brace. Patients with a pressure of initial correction (PIC) of 10.0 pounds per square inch or less were offered treatment with the brace. Patients with a PIC above 10.0 pounds per square inch were offered surgical correction. Between March 2013 and April 2016, 286 patients were treated with the brace; 260 were male (91%) and 26 were female (9%). Their mean age was 14 years (range, 4 to 21 years). Seventy-eight patients completed brace treatment; the mean treatment time was 14 months. Twenty-seven patients abandoned treatment because of lack of motivation, loss to follow-up, persistent protrusion of the sternal bone or flaring that required surgical correction, failure of treatment because of a bifid rib, fear of locking the brace, and delayed correction. One hundred eighty-one patients are still wearing the brace, either in the active or in the retainer phase. Patients with a high PIC also showed improvement when they were compliant. Adverse events were minor and included skin lesions (n = 4, 1%) and vasovagal reactions at the start of therapy (n = 3, 1%). These data show that brace therapy can be considered a valuable treatment option to correct pectus carinatum in patients with a flexible thorax. Copyright © 2017 The Society of Thoracic Surgeons.

Liver transplantation is currently a standard therapy for patients with end-stage liver diseases and hepatocellular carcinoma. Given that liver transplantation has undergone a thriving development in these decades, the survival rates after liver transplantation have markedly improved as a result of the critical advancement in surgical techniques, immunosuppressive therapies, and postoperative care. However, infection remains a fatal complication after liver transplantation surgery. In particular, enterogenic infection represents a major complication in liver transplant recipients. This article gives an overview of infection cases after liver transplantation and focuses on the discussion of enterogenic infection in terms of its pathophysiology, risk factor, outcome, and treatment.

Functional neurosurgery has undergone rapid growth over the last few years fueled by advances in imaging technology and novel treatment modalities. These advances have led to new surgical treatments using minimally invasive and precise techniques for conditions such as Parkinson's disease, essential tremor, epilepsy, and psychiatric disorders. Understanding the goals and technological issues of these procedures is imperative for the anesthesiologist to ensure safe management of patients presenting for functional neurosurgical procedures. In this review, we discuss the advances in neurosurgical techniques for deep brain stimulation, focused ultrasound and minimally invasive laser-based treatment of refractory epilepsy and provide a guideline for anesthesiologists caring for patients undergoing these procedures.

The treatment option for cancers of the tongue is glossectomy, which may be partial, sub-total, or total, depending on the size of the tumour. Glossectomies result in speech deficits for these patients, and rehabilitative therapy involving communication modalities is highly recommended. Sign language is a possible therapeutic solution for post-glossectomy oral cancer patients. Patients with tongue cancers who have undergone total glossectomy as a surgical treatment can utilise sign language to replace their loss of speech production and maintain their engagement in life. This manuscript emphasises the importance of sign language in rehabilitation strategies in post-glossectomy patients. PMID:28947881

Bergese, Sergio D; Onel, Erol; Portillo, Juan

2011-11-01

SUMMARY An extended-release, multivesicular liposome-encapsulated form of the local anesthetic bupivacaine, DepoFoam(®) bupivacaine (proposed proprietary name EXPAREL™), is in development for use as part of a multimodal regimen for the treatment of postsurgical pain. Placebo- and active-controlled clinical trials in patients who have undergone either orthopedic or soft-tissue procedures indicate that a single local administration into the surgical site results in analgesic activity for up to 3-4 days and decreases the use of opioid rescue medication. The safety profile of DepoFoam bupivacaine appears to be similar to that of bupivacaine HCl, and adverse events are dose-related.

Veterinary medicine has undergone a rapid increase in specialization over the last three decades. Veterinarians now routinely perform joint replacement, neurosurgery, limb-sparing surgery, interventional radiology, radiation therapy, and other complex medical procedures. Many procedures involve advanced imaging and surgical planning. Evidence-based medicine has also become part of the modus operandi of veterinary clinicians. Modeling and additive manufacturing can provide individualized or customized therapeutic solutions to support the management of companion animals with complex medical problems. The use of metal additive manufacturing is increasing in veterinary orthopedic surgery. This review describes and discusses current and potential applications of metal additive manufacturing in veterinary orthopedic surgery.

This paper reports a case of a 57-year old female who had sustained a blunt ocular trauma resulting in anterior dislocation of the crystalline lens and acute painful visual loss in the left eye. The patient was managed with anterior chamber intracapsular phacoemulsification through a small anterior capsulotomy, pars plana vitrectomy, and surgical iridotomy. Aphakia was corrected by a contact lens. Two months after the surgery, the best corrected visual acuity was 0.9 in the left eye. The vision and retina remained stable in her follow-up examination 1 year later. Anterior dislocation of the crystalline lens can cause severe complications so that dislocated lens should be removed immediately.

The wound is a damage of tissue. The process of healing is influenced by many systemic and local factors. The most crucial and the most discussed local factor of wound healing is infection. Surgical site infection in the wound is caused by micro-organisms. This information is known for many years, however the conditions leading to an infection occurrence have not been sufficiently described yet. Correct sampling technique, correct storage, transportation, evaluation, and valid interpretation of these data are very important in clinical practice. There are many methods for microbiological sampling, but the best one has not been yet identified and validated. We aim to discuss the problem with the focus on the imprint technique.

Management of the constricted or obliterated vagina demands an understanding and recognition of the potential etiologies leading to this presentation. A thorough and comprehensive medical and surgical review is required to arrive at an accurate diagnosis, which then will guide medical or surgical intervention. It is paramount to recognize when underlying medical conditions are contributing to these conditions and to begin medical therapy; failure to do so will often yield suboptimal results. When these conditions arise after surgical interventions, compensatory surgical techniques that correct upper and lower vaginal strictures or obliteration include incision through the stricture, vaginal advancement, Z-plasty, skin grafts, perineal flaps, and abdominal flaps and grafts. Postoperative surveillance and dilation are critical to optimize long-term success.

We conducted the present study to determine the usefulness of routinely inserting a pediatric airway exchange catheter (PAEC) before tracheal extubation of adult patients who had undergone maxillofacial or major neck surgery and have risk factors for difficult reintubation. A prospective, observational and clinical study was performed in the 25-bed general intensive care unit of a university hospital. Thirty-six adult patients who underwent maxillofacial or major neck surgery and had risk factors for difficult reintubation were extubated after insertion of the PAEC. Four of 36 (11.1%) patients required emergency reintubation after 2, 4, 6 and 18 hours after tracheal extubation, respectively. Reintubation of these patients, which was thought to be nearly impossible by direct laryngoscopy, was easily achieved over the PAEC. The PAEC can be a life-saving device during reintubation of patients with risk factors for difficult reintubation such as laryngeo-pharyngeal oedema due to surgical manipulation or airway obstruction resulting from haematoma and anatomic changes. We therefore suggest the routine use of the PAEC in patients undergoing major maxillofacial or major neck surgery.

Transforaminal endoscopic discectomy and foraminotomy is a well-described minimally invasive technique for surgically treating lumbar radiculopathy caused by a herniated disc and foraminal narrowing. To describe the technique and feasibility of transforaminal foraminoplasty for the treatment of lumbar radiculopathy in patients who have already undergone instrumented spinal fusion. Retrospective study. Hospital and ambulatory surgery center After Institutional Review Board approval, charts from 18 consecutive patients with lumbar radiculopathy and instrumented spinal fusions who underwent endoscopic procedures between 2008 and 2013 were reviewed. The average pain relief one year postoperatively was reported to be 67.0%, good results as defined by MacNab. The average preoperative VAS score was 9.14, indicated in our questionnaire as severe and constant pain. The average one year postoperative VAS score was 3.00, indicated in our questionnaire as mild and intermittent pain. This is a retrospective study and only offers one year follow-up data for patients with instrumented fusions who have undergone endoscopic spine surgery. Transforaminal endoscopic discectomy and foraminotomy could be used as a safe, yet, minimally invasive and innovative technique for the treatment of lumbar radiculopathy in the setting of previous instrumented lumbar fusion.

Objectives. To determine in-hospital mortality and complications of cardiac surgery in pediatric patients and identify predictors of hospital mortality. Methods. Records of pediatric patients who had undergone cardiac surgery in 2005 were reviewed retrospectively. The risk adjustment for congenital heart surgery (RACHS-1) method, the Aristotle basic complexity score (ABC score), and the Society of Thoracic Surgeons and the European Association for Cardiothoracic Surgery Mortality score (STS-EACTS score) were used as measures. Potential predictors were analyzed by risk analysis. Results. 230 pediatric patients had undergone congenital cardiac surgery. Overall, the mortality discharge was 6.1%. From the ROC curve of the RACHS-1, the ABC level, and the STS-EACTS categories, the validities were determined to be 0.78, 0.74, and 0.67, respectively. Mortality risks were found at the high complexity levels of the three tools, bypass time >85 min, and cross clamp time >60 min. Common morbidities were postoperative pyrexia, bleeding, and pleural effusion. Conclusions. Overall mortality and morbidities were 6.1%. The RACHS-1 method, ABC score, and STS-EACTS score were helpful for risk stratification. PMID:21738856

Since the performance of the first laparoscopic cardiomyotomy for achalasia cardia in 1991, the popularity of the minimally invasive approach for this troublesome disease has been growing. We present our experience of 226 patients who underwent laparoscopic cardiomyotomy and discuss the relevant issues. A retrospective analysis was carried out of 226 patients who have undergone laparoscopic cardiomyotomy since 1993. The preoperative workup, surgical technique, and postoperative management are described. Patients included 146 males and 80 females; average age was 36.4 years (range, 6 to 85). Mean duration of symptoms was 1.4 years. Nearly half of the patients (112) had undergone prior pneumatic dilatation. In 20 patients, myotomy alone was done, 44 patients had a Dor's fundoplication, and 162 had Toupet's fundoplication. The average operating time was 96 minutes. Mean postoperative hospital stay was 2.2 days. Dysphagia was eliminated in 88.9% of the patients with an overall morbidity of 4.4% and nil mortality over a mean follow-up of 4.3 years. Laparoscopic cardiomyotomy with Toupet's fundoplication is a safe and effective treatment of achalasia cardia. Dor's fundoplication is done selectively, especially when suspicion is present of mucosal injury.

Methods: A retrospective analysis was carried out of 226 patients who have undergone laparoscopic cardiomyotomy since 1993. The preoperative workup, surgical technique, and postoperative management are described. Results: Patients included 146 males and 80 females; average age was 36.4 years (range, 6 to 85). Mean duration of symptoms was 1.4 years. Nearly half of the patients (112) had undergone prior pneumatic dilatation. In 20 patients, myotomy alone was done, 44 patients had a Dor's fundoplication, and 162 had Toupet's fundoplication. The average operating time was 96 minutes. Mean postoperative hospital stay was 2.2 days. Dysphagia was eliminated in 88.9% of the patients with an overall morbidity of 4.4% and nil mortality over a mean follow-up of 4.3 years. Conclusion: Laparoscopic cardiomyotomy with Toupet's fundoplication is a safe and effective treatment of achalasia cardia. Dor's fundoplication is done selectively, especially when suspicion is present of mucosal injury. PMID:17931518

A computed tomographic study. To investigate the change in abdominal morphology in surgically treated patients with ankylosing spondylitis (AS) and thoracolumbar kyphosis. Severe thoracolumbar kyphosis in patients with AS exerts pressure on the abdominal cavity and subsequently causes intra-abdominal complications. Several spinal osteotomy techniques have been widely used to correct AS-related thoracolumbar kyphosis. To date, the changed abdominal morphology in patients with AS undergoing surgical correction of thoracolumbar kyphosis has not been addressed. A total of 29 patients with AS undergoing lumbar pedicle subtraction osteotomy for correction of thoracolumbar kyphosis were retrospectively reviewed. Computed tomographic scans of the spine were used to measure the longitudinal, transverse, and anterior-posterior diameters of the abdominal cavity. Furthermore, the abdominal cavity was considered as an ellipsoid structure, thereby allowing calculation of its volume. Radiographical evaluations included global kyphosis (GK), thoracic kyphosis, lumbar lordosis (LL), and angle of fusion levels (AFL). The longitudinal diameter of abdominal cavity significantly increased (P < 0.01), whereas the transverse and anterior-posterior diameters of the abdominal cavity did not change, postoperatively (P > 0.05). Significant changes in GK, LL, and AFL were observed (P < 0.01). The abdominal cavity volume (ACV) increased by an average of 652  mL. The change in ACV was significantly correlated with the changes in GK (r = 0.453, P = 0.014), LL (r = 0.42, P = 0.023), and AFL (r = 0.388, P = 0.037). The increased ACV after correction of thoracolumbar kyphosis was quantitatively confirmed by this study. Thus, the improvement in digestive function after correction of thoracolumbar kyphosis secondary to AS, which has been previously documented, may be because of an increase in ACV. Moreover, spine surgeons should be aware of the potential risk for the development of abdominal complications caused by the lengthening of longitudinal diameter of the abdominal cavity. 3.

Surgical education has undergone radical changes in the past decade. The introductions of laparoscopic surgery and endovascular techniques have required program directors to alter surgical training. The 6 competencies are now in place. One issue that still needs to be addressed is the business aspect of surgical practice. Often residents complete their training with minimal or no knowledge on coding of charges or basic aspects on how to set up a practice. We present our program, which has been in place over the past 2 years and is designed to teach the residents practice management. The program begins with a series of 10 lectures given monthly beginning in August. Topics include an introduction to types of practices available, negotiating a contract, managed care, and marketing the practice. Both medical and surgical residents attend these conferences. In addition, the surgical residents meet monthly with the business office to discuss billing and coding issues. These are didactic sessions combined with in-house chart reviews of surgical coding. The third phase of the practice management plan has the coding team along with the program director attend the outpatient clinic to review in real time the evaluation and management coding of clinic visits. Resident evaluations were completed for each of the practice management lectures. The responses were recorded on a Likert scale. The scores ranged from 4.1 to 4.8 (average, 4.3). Highest scores were given to lectures concerning negotiating employee agreements, recruiting contracts, malpractice insurance, and risk management. The medical education department has tracked resident coding compliance over the past 2 years. Surgical coding compliance increased from 36% to 88% over a 12-month period. The program director who participated in the educational process increased his accuracy from 50% to 90% over the same time period. When residents finish their surgical training they need to be ready to enter the world of business. These needs will be present whether pursuing a career in academic medicine or the private sector. A program that focuses on the business aspect of surgery enables the residents to better navigate the future while helping to fulfill the systems-based practice competency.

Intractable duodenal ulcer caused by transmural migration of gossypiboma into the duodenum - a case report and literature review

PubMed Central

2014-01-01

Background Gossypiboma is a term used to describe a mass that forms around a cotton sponge or abdominal compress accidentally left in a patient during surgery. Transmural migration of an intra-abdominal gossypiboma has been reported to occur in the digestive tract, bladder, vagina and diaphragm. Open surgery is the most common approach in the treatment of gossypiboma. However, gossypibomas can be extracted by endoscopy while migrating into the digestive tract. We report a case of intractable duodenal ulcer caused by transmural migration of gossypiboma successfully treated by duodenorrhaphy. A systemic literature review is provided and a scheme of the therapeutic approach is proposed. Case presentation A 61-year-old Han Chinese man presented with intermittent epigastric pain for the last 10 months. He had undergone laparoscopic cholecystectomy conversion to open cholecystectomy for acute gangrenous cholecystitis 10 months ago at another hospital. Transmural migration of gossypiboma into the duodenum was found. Endoscopic intervention failed to remove the entire gauze, and duodenal ulcer caused by the gauze persisted. Surgical intervention was performed and the gauze was removed successfully. The penetrated ulcer was repaired with duodenorrhaphy. The postoperative period was uneventful. We systematically reviewed the literature on transmural migration of gossypiboma into duodenum and present an overview of published cases. Our PubMed search yielded seven reports of transmural migration of retained surgical sponge into the duodenum. Surgical interventions were necessary in two patients. Conclusion Transmural migration of gossypiboma into the duodenum is a rare surgical complication. The treatment strategies include endoscopic extraction and surgical intervention. Prompt surgical intervention should be considered for emergent conditions such as active bleeding, gastrointestinal obstruction, or intra-abdominal sepsis. For non-emergent conditions, surgical intervention could be considered for intractable cases in which endoscopic extraction failed. PMID:24917191

The purpose of this study was to evaluate the intermediate surgical results of Ahmed glaucoma valve (AGV) implantation in patients less than 7 years of age, with advanced primary congenital glaucoma who have failed previous surgeries. Consecutive patients with advanced primary congenital glaucoma that failed previous operations and had undergone subsequent AGV implantation were evaluated retrospectively. Surgical success was defined as 1) intraocular pressure (IOP) ≥6 and ≤21 mmHg; 2) IOP reduction of at least 30% relative to preoperative values; and 3) without the need for additional surgical intervention for IOP control, loss of light perception, or serious complications. Fourteen eyes of eleven patients were studied. Preoperatively, the average axial length was 27.71±1.52 (25.56-30.80) mm, corneal diameter was 14.71±1.07 (13.0-16.0) mm, cup-to-disc ratio was 0.95±0.04 (0.9-1.0), and IOP was 39.5±5.7 (30-55) mmHg. The mean follow-up time was 18.29±10.96 (5-44, median 18) months. There were significant reductions in IOPs and the number of glaucoma medications (P<0.001) postoperatively. The IOPs after operation were 11.3±3.4, 13.6±5.1, 16.3±2.7, and 16.1±2.6 mmHg at 1 month, 6 months, 12 months, and 18 months, respectively. Kaplan-Meier estimates of the cumulative probability of valve success were 85.7%, 71.4%, and 71.4% at 6, 12, and 18 months, respectively. Severe surgical complications, including erosion of tube, endophthalmitis, retinal detachment, choroidal detachment, and delayed suprachoroidal hemorrhage, occurred in 28.6% cases. AGV implantation remains a viable option for patients with advanced primary congenital glaucoma unresponsive to previous surgical intervention, despite a relatively high incidence of severe surgical complications.

Purpose Using a network meta-analysis approach, our study aims to develop a ranking of the six surgical procedures, that is, Plate, titanium elastic nail (TEN), tension band wire (TBW), hook plate (HP), reconstruction plate (RP) and Knowles pin, by comparing the post-surgery constant shoulder scores in patients with clavicular fracture (CF). Methods A comprehensive search of electronic scientific literature databases was performed to retrieve publications investigating surgical procedures in CF, with the stringent eligible criteria, and clinical experimental studies of high quality and relevance to our area of interest were selected for network meta-analysis. Statistical analyses were conducted using Stata 12.0. Results A total of 19 studies met our inclusion criteria were eventually enrolled into our network meta-analysis, representing 1164 patients who had undergone surgical procedures for CF (TEN group = 240; Plate group = 164; TBW group  =  180; RP group  =  168; HP group  =  245; Knowles pin group  =  167). The network meta-analysis results revealed that RP significantly improved constant shoulder score in patients with CF when compared with TEN, and the post-operative constant shoulder scores in patients with CF after Plate, TBW, HP, Knowles pin and TEN were similar with no statistically significant differences. The treatment relative ranking of predictive probabilities of constant shoulder scores in patients with CF after surgery revealed the surface under the cumulative ranking curves (SUCRA) value is the highest in RP. Conclusion The current network meta-analysis suggests that RP may be the optimum surgical treatment among six inventions for patients with CF, and it can improve the shoulder score of patients with CF. Implications for Rehabilitation RP improves shoulder joint function after surgical procedure. RP achieves stability with minimal complications after surgery. RP may be the optimum surgical treatment for rehabilitation of patients with CF.

The purpose of this retrospective study was to compare the outcome for dogs with surgically treated large versus small intestinal volvulus between October 2009 and February 2014. A total of 15 dogs met the inclusion criteria and underwent an abdominal exploratory. Nine dogs were diagnosed with large intestinal volvulus during the study period, and all nine had surgical correction for large intestinal volvulus. All dogs were discharged from the hospital. Of the seven dogs available for phone follow-up (74 to 955 days postoperatively), all seven were alive and doing well. Six dogs were diagnosed with small intestinal volvulus during the study period. One of the six survived to hospital discharge. Three of the six were euthanized at the time of surgery due to an extensive amount of necrotic bowel. Of the three who were not, one died postoperatively the same day, one died 3 days later, and one dog survived for greater than 730 days. Results concluded that the outcome in dogs with surgically corrected large intestinal volvulus is excellent, compared with a poor outcome in dogs with small intestinal volvulus. The overall survival to discharge for large intestinal volvulus was 100%, versus 16% for small intestinal volvulus.

Abstract. The fidelity of image-guided neurosurgical procedures is often compromised due to the mechanical deformations that occur during surgery. In recent work, a framework was developed to predict the extent of this brain shift in brain-tumor resection procedures. The approach uses preoperatively determined surgical variables to predict brain shift and then subsequently corrects the patient’s preoperative image volume to more closely match the intraoperative state of the patient’s brain. However, a clinical workflow difficulty with the execution of this framework is the preoperative acquisition of surgical variables. To simplify and expedite this process, an Android, Java-based application was developed for tablets to provide neurosurgeons with the ability to manipulate three-dimensional models of the patient’s neuroanatomy and determine an expected head orientation, craniotomy size and location, and trajectory to be taken into the tumor. These variables can then be exported for use as inputs to the biomechanical model associated with the correction framework. A multisurgeon, multicase mock trial was conducted to compare the accuracy of the virtual plan to that of a mock physical surgery. It was concluded that the Android application was an accurate, efficient, and timely method for planning surgical variables. PMID:28331887

The ultrasound imaging method was implemented to assess the spinal curve flexibility of scoliotic surgical candidates, or how much correction it can achieve while patients are bending or lying down. Fifteen participants were recruited. Pre-operative radiographs and ultrasound images in both standing and bending positions were acquired. The post-operative standing radiographs were obtained 1 wk after surgery. Two raters (RZ, EL) measured the ultrasound images twice, 1 wk apart. A curve correction index (C I ) was developed to estimate the curve flexibility. The C I from the pre-operative bending radiograph, ultrasound and post-operative radiograph were 0.51 ± 0.18; R1: 0.74 ± 0.08 vs R2: 0.72 ± 0.09 and 0.60 ± 0.10, respectively. The correlation of C I between ultrasound and post-operative radiography was slightly higher than the pre-operative bending and post-operative radiography. This pilot study demonstrated the bending ultrasound method is a promising supplemental tool to assess curve flexibility before surgical intervention for scoliotic surgical candidates.

In recent work, a framework was developed to predict the extent of this brain shift in brain-tumor resection procedures. The approach uses preoperatively determined surgical variables to predict brain shift and then subsequently corrects the patient's preoperative image volume to more closely match the intraoperative state of the patient's brain.

To examine the effect of pre-surgical orthodontics on the outcome of the secondary alveolar bone grafting in the patients with complete cleft lip and palate. Sixteen complete cleft lip and palate patients (9 males and 7 females) with collapsed upper arch or severe mal-positioned upper incisors were selected. The cleft was not easily grafted because of the poor access. The total cleft sites were 22 (10 patients with UCLP and 6 patients with BCLP). The age range of the patients was from 8 to 22 years. Pre-surgical orthodontic treatment was mainly to expand the collapsed upper arch and correct the mal-positioned upper incisors. After the secondary alveolar bone grafting, the patients were followed up and anterior occlusal radiograph/intraoral panograph were taken regularly. The observation period was from 6 months to 4 years. Bergland criteria were used to evaluate the interdental septal height. Upper arch expansion and the correction of the mal-positioned upper incisors done by the orthodontic treatment made the bone grafting procedure easier. The clinically successful rate reached 86%. The severe upper arch collapse and mal-positioned upper incisors in the patients with complete cleft lip and palate should be corrected orthodontically before the secondary alveolar bone grafting.

Spring-assisted cranioplasty is performed to correct the long and narrow head shape of children with sagittal synostosis. Such corrective surgery involves osteotomies and the placement of spring-like distractors, which gradually expand to widen the skull until removal about 4 months later. Due to its dynamic nature, associations between surgical parameters and post-operative 3D head shape features are difficult to comprehend. The current study aimed at applying population-based statistical shape modelling to gain insight into how the choice of surgical parameters such as craniotomy size and spring positioning affects post-surgical head shape. Twenty consecutive patients with sagittal synostosis who underwent spring-assisted cranioplasty at Great Ormond Street Hospital for Children (London, UK) were prospectively recruited. Using a nonparametric statistical modelling technique based on mathematical currents, a 3D head shape template was computed from surface head scans of sagittal patients after spring removal. Partial least squares (PLS) regression was employed to quantify and visualise trends of localised head shape changes associated with the surgical parameters recorded during spring insertion: anterior-posterior and lateral craniotomy dimensions, anterior spring position and distance between anterior and posterior springs. Bivariate correlations between surgical parameters and corresponding PLS shape vectors demonstrated that anterior-posterior (Pearson's [Formula: see text]) and lateral craniotomy dimensions (Spearman's [Formula: see text]), as well as the position of the anterior spring ([Formula: see text]) and the distance between both springs ([Formula: see text]) on average had significant effects on head shapes at the time of spring removal. Such effects were visualised on 3D models. Population-based analysis of 3D post-operative medical images via computational statistical modelling tools allowed for detection of novel associations between surgical parameters and head shape features achieved following spring-assisted cranioplasty. The techniques described here could be extended to other cranio-maxillofacial procedures in order to assess post-operative outcomes and ultimately facilitate surgical decision making.

Purpose: To describe the practical use of the extended No Action Level (eNAL) setup correction protocol for breast cancer patients with surgical clips and evaluate its impact on the setup accuracy of both tumor bed and whole breast during simultaneously integrated boost treatments. Methods and Materials: For 80 patients, two orthogonal planar kilovoltage images and one megavoltage image (for the mediolateral beam) were acquired per fraction throughout the radiotherapy course. For setup correction, the eNAL protocol was applied, based on registration of surgical clips in the lumpectomy cavity. Differences with respect to application of a No Action Level (NAL) protocolmore » or no protocol were quantified for tumor bed and whole breast. The correlation between clip migration during the fractionated treatment and either the method of surgery or the time elapsed from last surgery was investigated. Results: The distance of the clips to their center of mass (COM), averaged over all clips and patients, was reduced by 0.9 {+-} 1.2 mm (mean {+-} 1 SD). Clip migration was similar between the group of patients starting treatment within 100 days after surgery (median, 53 days) and the group starting afterward (median, 163 days) (p = 0.20). Clip migration after conventional breast surgery (closing the breast superficially) or after lumpectomy with partial breast reconstructive techniques (sutured cavity). was not significantly different either (p = 0.22). Application of eNAL on clips resulted in residual systematic errors for the clips' COM of less than 1 mm in each direction, whereas the setup of the breast was within about 2 mm of accuracy. Conclusions: Surgical clips can be safely used for high-accuracy position verification and correction. Given compensation for time trends in the clips' COM throughout the treatment course, eNAL resulted in better setup accuracies for both tumor bed and whole breast than NAL.« less

To discuss the skeletal and dentoalveolar characteristics of asymmetric mandibular excess malocclusions and to discuss the procedures of combined orthodontic-orthonganthic surgery treatments of asymmetric mandibular excess malocclusions. 25 cases treated by combined orthodontic-orthognathic surgery treatments were reviewed to find out the specialties of this kind of therapy. The asymmetric of mandible presents anterior and posterior teeth tipped both sagitally and horizontally, as well as upper and lower jaws incompatibility. The pre-surgical orthodontic treatments included decomposition of anterior and posterior teeth, leveling and aligning the teeth etc. The post-surgical orthodontic treatments were to detail the occlusions. The patients all got functional and aesthetic good results after the combined orthodontic-orthognathic surgery treatments. The asymmetric mandibular excess affects the harmony of the face badly, and the correction of it must be carried out by the combined orthodontic-orthognathic surgery treatments. The pre- and post-surgical orthodontic treatments are the key stages to make the skeletal corrections stable.

Congenital adrenal hyperplasia (CAH) is associated with a genital deformation that might cause a negative body image. The genital ambiguity is generally "corrected" surgically during early infancy. The advantage is a psychological benefit. The disadvantages are multiple surgical procedures and the loss of orgasm. A 22-year-old woman with CAH consulted for genital reconstructive surgery. She had a pseudopenis of 4 cm and could achieve an orgasm by masturbating. During surgery, the penis was dismantled and with the preserved glans penis and the corpora cavernosa, a clitoris and vestibules were constructed, respectively. On the basis of the anamneses during the follow-up, she had a functional vagina and could still achieve orgasms. Genital correction surgery for CAH at an older age was easier, could be done in 1 step, and enabled the preservation of orgasm.

Although surgical treatment protocols for cleft lip and palate patients have been established, many patients still have some soft tissue defects after complete healing from surgical interventions. These are excess soft tissue, high attached fraena and firmed tethering scares. These soft tissue defects resulted shallowing of vestibule, restricted tooth movement, compromised periodontal health and trended to limit the maxillary growth. The aim of this case report was to present a method of correcting soft tissue defects after conventional surgery in cleft lip and palate patient by using combined laser surgery and orthodontic appliance. A bilateral cleft lip and palate patient with a clinical problem of shallow upper anterior vestibule after alveolar bone graft received a vestibular extension by using CO 2 laser with ablation and vaporization techniques at 4 W and continuous wave. A customized orthodontic appliance, called a buccal shield, was placed immediately after surgery and retained for 1 month to 3 months until complete soft tissue healing. The procedures were performed 2 episodes. Both interventions used the same CO 2 laser procedure. The first treatment resulted in partial re-attachment of soft tissue at surgical area. The second laser operation with the proper design of buccal shield providing passive contact with more extended flange resulting in a favorable outcome from 1 year follow up. Then the corrective orthodontic treatment could be continued effectively. The CO 2 laser surgery was a proper treatment for correcting soft tissue defects and the design of buccal shield was a key for success in molding surgical soft tissue.

Temporary gynecomastia in the form of breast buds is a common finding in young male subjects. In adults, permanent gynecomastia is an aesthetic impairment that may result in interest in surgical correction. Gynecomastia in body builders creates an even greater distress for patients seeking surgical treatment because of the demands of professional competition. The authors present their experience with gynecomastia in body builders as the largest study of such a group in the literature. Between the years 1980 and 2013, 1574 body builders were treated surgically for gynecomastia. Of those, 1073 were followed up for a period of 1 to 5 years. Ages ranged from 18 to 51 years. Subtotal excision in the form of subcutaneous mastectomy with removal of at least 95 percent of the glandular tissue was used in virtually all cases. In cases where body fat was extremely low, liposuction was performed in fewer than 2 percent of the cases. Aesthetically pleasing results were achieved in 98 percent of the cases based on the authors' patient satisfaction survey. The overall rate of hematomas was 9 percent in the first 15 years of the series and 3 percent in the final 15 years. There were no infections, contour deformities, or recurrences. This study demonstrates the importance of direct excision of the glandular tissue over any other surgical technique when correcting gynecomastia deformities in body builders. The novice surgeon is advised to proceed with cases that are less challenging, primarily with patients that require excision of small to medium glandular tissue. Therapeutic, IV.

Investigate the prevalence and vision-related outcomes of cataract surgery in an area of high cataract surgical rate. Cluster sampling was used in randomly selecting individuals > or = 50 years of age in 2007. Participants were queried regarding year and place of previous cataract surgery. Cataract surgical procedures and evidence of surgical complications were recorded. The principal cause was identified for eyes presenting with visual acuity (VA) < or = 20/40. A total of 4,738 persons were examined and 834 (17.6%) had cataract surgery. Intra-ocular lenses (IOLs) were used in 84.1% of the 1,299 cataract-operated eyes, with more than half of these having manual small incision surgery. Surgical coverage among the cataract blind (visual acuity [VA] < 20/200) was estimated as 72.2%. Coverage was associated with older age, literacy, and urban residence; gender was not significant. Among cataract-operated eyes, 18.7% presented with VA > or = 20/32 and 18.0% were < 20/200. With best-corrected acuity, the corresponding percentages were 55.7% and 11.0%. Presenting and best-corrected VA > or = 20/63 were associated with young age, literacy, and IOL surgery; urban residence and surgery in non-governmental organizations (NGO)/private facilities were also significant for presenting VA; and recent surgery was significant for best-corrected VA. Refractive error was the main cause of vision impairment/blindness in cataract-operated eyes. Refractive error and posterior capsule opacification, easily treatable causes of visual impairment, are common among the operated. A greater emphasis on the quality of visual acuity outcomes along with sustained efforts to provide access to affordable surgery is needed.

Prospective case series. To study the safety, efficacy, and long-term outcomes of single-stage surgical intervention for congenital spinal deformity and intraspinal anomalies. Congenital spinal deformities associated with intraspinal anomalies are usually treated sequentially, first by treating the intraspinal anomalies followed by deformity correction after a period of 3-6 months. Recently, a single-stage approach has been reported to show better postoperative results and reduced complication rates. Thirty patients (23 females and seven males) were prospectively evaluated for the simultaneous surgical treatment of congenital spinal deformity with concurrent intraspinal anomalies from May 2006 to October 2016. The average age at presentation was 9.8±3.7 years, with the average follow-up duration being 49.06±8.6 months. Clinical records were evaluated for clinical, radiological, perioperative, and postoperative data. The average angle of deformity was 56.53°±25.22° preoperatively, 21.13°±14.34° postoperatively, and 23.93°±14.99° at the final follow-up. The average surgical time was 232.58±53.56 minutes (range, 100-330 minutes), with a mean blood loss of 1,587.09±439.09 mL (range, 100-2,300 mL). Single stage surgical intervention for intraspinal anomalies with congenital spinal deformity correction, including adequate intra-operative wake-up test, is a viable option in appropriately selected patients and has minimum complication rates.

Purpose The aim of this study was to categorize concealed penis and buried penis by preoperative physical examination including the manual prepubic compression test and to describe a simple surgical technique to correct buried penis that was based on surgical experience and comprehension of the anatomical components. Materials and Methods From March 2007 to November 2010, 17 patients were diagnosed with buried penis after differentiation of this condition from concealed penis. The described surgical technique consisted of a minimal incision and simple fixation of the penile shaft skin and superficial fascia to the prepubic deep fascia, without degloving the penile skin. Results The mean age of the patients was 10.2 years, ranging from 8 years to 15 years. The median follow-up was 19 months (range, 5 to 49 months). The mean penile lengths were 1.8 cm (range, 1.1 to 2.5 cm) preoperatively and 4.5 cm (range, 3.3 to 5.8 cm) postoperatively. The median difference between preoperative and postoperative penile lengths was 2.7 cm (range, 2.1 to 3.9 cm). There were no serious intra- or postoperative complications. Conclusions With the simple anchoring of the penopubic skin to the prepubic deep fascia, we obtained successful subjective and objective outcomes without complications. We suggest that this is a promising surgical method for selected patients with buried penis. PMID:22195270

Due to the increasing complexity of the surgical working environment, increasingly technical solutions must be found to help relieve the surgeon. This objective is supported by a structured storage concept for all relevant device data. In this work, we present a concept and prototype development of a storage system to address intraoperative medical data. The requirements of such a system are described, and solutions for data transfer, processing, and storage are presented. In a subsequent study, a prototype based on the presented concept is tested for correct and complete data transmission and storage and for the ability to record a complete neurosurgical intervention with low processing latencies. In the final section, several applications for the presented data recorder are shown. The developed system based on the presented concept is able to store the generated data correctly, completely, and quickly enough even if much more data than expected are sent during a surgical intervention. The Surgical Data Recorder supports automatic recognition of the interventional situation by providing a centralized data storage and access interface to the OR communication bus. In the future, further data acquisition technologies should be integrated. Therefore, additional interfaces must be developed. The data generated by these devices and technologies should also be stored in or referenced by the Surgical Data Recorder to support the analysis of the OR situation.

OBJECTIVE Adolescent idiopathic scoliosis (AIS) is the most common form of scoliosis. Limited literature exists defining risk factors associated with outcomes during initial hospitalization in these patients. In this study, the authors investigated patient demographics, clinical and hospital characteristics impacting short-term outcomes, and costs in adolescent patients undergoing surgical deformity correction for idiopathic scoliosis. Additionally, the authors elucidate the impact of hospital surgical volume on outcomes for these patients. METHODS Using the National Inpatient Sample database and appropriate International Classification of Diseases, 9th Revision codes, the authors identified adolescent patients (10-19 years of age) undergoing surgical deformity correction for idiopathic scoliosis during 2001-2014. For national estimates, appropriate weights provided by the Agency of Healthcare Research and Quality were used. Multivariable regression techniques were employed to assess the association of risk factors with discharge disposition, postsurgical neurological complications, length of hospital stay, and hospitalization costs. RESULTS Overall, 75,106 adolescent patients underwent surgical deformity correction. The rates of postsurgical complications were estimated at 0.9% for neurological issues, 2.8% for respiratory complications, 0.8% for cardiac complications, 0.4% for infections, 2.7% for gastrointestinal complications, 0.1% for venous thromboembolic events, and 0.1% for acute renal failure. Overall, patients stayed at the hospital for an average of 5.72 days (median 5 days) and on average incurred hospitalization costs estimated at $54,997 (median $47,909). As compared with patients at low-volume centers (≤ 50 operations/year), those undergoing surgical deformity correction at high-volume centers (> 50/year) had a significantly lower likelihood of an unfavorable discharge (discharge to rehabilitation) (OR 1.16, 95% CI 1.03-1.30, p = 0.016) and incurred lower costs (mean $33,462 vs $56,436, p < 0.001) but had a longer duration of stay (mean 6 vs 5.65 days, p = 0.002). In terms of neurological complications, no significant differences in the odds ratios were noted between high- and low-volume centers (OR 1.23, 95% CI 0.97-1.55, p = 0.091). CONCLUSIONS This study provides insight into the clinical characteristics of AIS patients and their postoperative outcomes following deformity correction as they relate to hospital volume. It provides information regarding independent risk factors for unfavorable discharge and neurological complications following surgery for AIS. The proposed estimates could be used as an adjunct to clinical judgment in presurgical planning, risk stratification, and cost containment.

To identify the characteristic features of pneumothorax patients treated surgically. The retrospective study was conducted at Gazi Yasargil Education and Research Hospital Thoracic Surgery Clinic, Diyarbakir, Turkey and comprised records of pneumothorax patients from January 2004 to December 2014. They were divided into two groups as spontaneous and traumatic. Patients who had not undergone any surgical intervention were excluded. Mean age, gender distribution, location of the disease, type of pneumothorax, and treatment method were noted. Among patients with spontaneous pneumothorax, age and months distribution, smoking habits, pneumothorax size, and treatment method were assessed. The effect of gender, location, comorbid disease, smoking, subgroup of disease, and pneumothorax size on surgical procedures were also investigated. The mean age of the 672 patients in the study was 34.5±6.17 years. There were 611(91%) men and 61(9%) women. Disease was on the right side in 360(53.6%) patients, on the left side in 308(45.8%), and bilateral in 4(0.59%). Besides, 523(77.8%) patients had spontaneous, and 149(22.7%) had traumatic pneumothorax. Overall, 561(83.5%) patients had been treated with tube thoracostomy, whereas 111(16.5%) were treated with thoracotomy/thoracoscopic surgery. The presence of comorbid diseases, being primary, and being total or subtotal according to partial were found to create predisposition to thoracotomy/ thoracoscopic surgery (p<0.05 each). In the case of pneumothorax being total, the presence of comorbid diseases, and the increase in pneumothorax size, thoracotomy or thoracoscopic surgery is preferred.

It is not uncommon to encounter patients who have undergone surgery for gynecomastia but who were not fully satisfied with the results. Although various approaches and techniques based on presurgical classification systems aimed at yielding the best possible surgical outcomes have been offered, standardized recommendation that is generally accepted by surgeons is lacking. The author reports on a new classification system and treatment protocol for the surgical treatment of gynecomastia. A system was developed that classifies patients into 3 types based on skin elasticity, presence of an inframammary fold (IMF), and mammary ptosis. Surgical excision of the breast mass was followed by a combination of destruction of the IMF, ultrasound-assisted lipoplasty (UAL) of the chest wall, ultrasound stimulation of the breast skin, and periareolar deepithelialization, depending on the gyneocomastia classification. This classification and the treatment protocol were applied to 30 patients, 13 to 60 years of age, between January 2005 and December 2007. Among these patients, 12 were classified as type 1, 6 as type 2, and 12 as type 3. Follow-up ranged from 3 to 18 months. Complications were common to all types of cases and techniques. They included 2 hematomas, 1 wound dehiscence, 5 cases of residual gynecomastia in those patients who underwent UAL alone, and 3 minor aesthetic problems near areolae. The proposed new classification and treatment protocol were found to help solve problems associated with surgical outcomes for all types of gynecomastia, although the issue of residual gynecomastia in patients undergoing UAL alone requires further study.

The tongue-lip adhesion has undergone several modifications in an attempt to reduce surgical complications and failure rates. Current techniques rely on the use of a button at the tongue base for suspension, which raises concerns about possible aspiration and interference with oral motor function and bottle-feeding. A new technique for tongue-lip adhesion is proposed that adds a tongue suspension to the standard surgical adhesion. A total of 22 patients with Pierre Robin sequence who received a tongue-lip adhesion via a tongue suspension technique were reviewed. The surgical technique differs from the standard surgical approach by the use of a suture weave across the base of the tongue instead of a standard button to suspend the tongue anteriorly. Average age at the time of tongue-lip adhesion was 13.9 days, with a mean operative time of 88.8 minutes. A marked improvement in postoperative oxygenation was seen in the majority of patients. One dehiscence occurred secondary to a traumatic postoperative extubation, eventually requiring a tracheostomy for subglottic stenosis. A technical innovation for performing a tongue-lip adhesion using a tongue suspension in conjunction with a standard transverse adhesion of the lip is described. The advantage of the tongue-lip adhesion with suspension includes immediate postoperative extubation, as well as removal of concerns regarding button aspiration and possible interference in early developmental oral motor function and bottle-feeding. This technique is reproducible, expanding the craniofacial surgeon's armamentarium for the management of difficult airways in Pierre Robin sequence.

To describe the indications for and approaches to vitreoretinal surgery in patients with osteo-odonto-keratoprosthesis (OOKP). Retrospective case series. This was a retrospective review of all patients who had undergone OOKP surgery between 2003 and 2012 at our center. OOKP procedures were performed for severe ocular surface disease according to the indications and techniques described in the patient demographics of the Rome-Vienna Protocol. Indications for retinal surgery, surgical outcomes, and intraoperative and postoperative complications were documented. Operative techniques were reviewed from the surgical records, and any subsequent surgeries were also recorded. Thirty-six patients underwent OOKP, and retinal surgery was indicated in 13 (36%). The indications for and approaches to surgery were retinal detachment repair using an Eckardt temporary keratoprosthesis; assessment of retina and optic nerve health prior to OOKP surgery, using either a temporary keratoprosthesis or an endoscope; endoscopic cyclophotocoagulation for intractable glaucoma; endoscopic trimming of a retroprosthetic membrane; or vitrectomy for endophthalmitis with visualization through the OOKP optic using the binocular indirect viewing system. In all cases, retinal surgical aims were achieved with a single procedure. Postoperative vitreous hemorrhage occurred in 16 patients (44%), but all resolved spontaneously. OOKPs represent the last hope for restoration of vision in severe ocular surface disease, and the retinal surgeon is frequently called upon in the assessment and management of these patients. Temporary keratoprostheses and endoscopic vitrectomies are valuable surgical tools in these challenging cases, improving functional outcomes without compromising OOKP success.

To present a novel modification of surgical technique to treat female urethral stricture (FUS) by a vaginal-sparing ventral buccal mucosal urethroplasty. Recurrent FUS represents an uncommon, though difficult clinical scenario to manage definitively. A variety of surgical techniques have been described to date, yet a lack of consensus on the optimal procedure persists. We present a 51-year-old female with urethral stricture involving the entire urethra. Suspected etiology was iatrogenic from cystoscopy 17 years prior. Since then, the patient had undergone at least 25 formal urethral dilations and periods of self-dilation. In lithotomy position, the urethra was dilated to accommodate forceps, and ventral urethrotomy carried out sharply, exposing a bed of periurethral tissue. Buccal mucosa was harvested, and a ventral inlay technique facilitated by a nasal speculum, was used to place the graft from the proximal urethra/bladder neck to urethral meatus without a vaginal incision. Graft was sutured into place, and urethral Foley catheter inserted. The vaginal-sparing ventral buccal mucosal graft urethroplasty was deemed successful as of last follow-up. Flexible cystoscopy demonstrated patency of the repair at 6 months. At 10 months of follow-up, the patient was voiding well, with no urinary incontinence. No further interventions have been required. This case describes a novel modification of surgical technique for performing buccal mucosal urethroplasty for FUS. By avoiding incision of the vaginal mucosa, benefits may include reduced: morbidity, urinary incontinence, and wound complications including urethro-vaginal fistula.

Surgical treatment is the first option for patients with obstructive multinodular goiter. The extent of the resection and the use of postoperative hormonal therapy are, on the other hand, still under debate. To analyze the results of surgical treatment in 101 patient with multinodular goiter seen from 1980 to 1995. The clinical/pathologic charts of all patients were reviewed with emphasis to the clinical diagnosis, extent of resection, final histology, type and number of complications, and long-term follow-up. The mean follow-up was three years (range 0.5-12). Ten males and 91 females with a mean age of 46 years were included. Surgery was recommended for a nodule suspicious of malignancy in 60 patients, for airway compression in 33, and for cosmetic reasons in eight. Unilateral lobectomy was performed in 30, bilateral subtotal thyroidectomy in 55 and total thyroidectomy in 16. Postoperative hormone therapy was administrated to 83 patients. Surgical complications occurred in six patients. Four developed permanent hypoparathyroidism and two vocal cord paralysis. There was no operative mortality. A final diagnosis of multinodular goiter was established in 89 whereas 12 had cancer. There were three asymptomatic recurrences in the group with benign lesions (they had undergone unilateral lobectomy followed by hormonal therapy). Bilateral subtotal thyroidectomy was the best treatment for multinodular goiter in our series. This procedure had few complications and there was no recurrence of the disease.

Stereotactic amygdalotomy has been utilized as a surgical treatment for severe aggressive behavioral disorders. Several clinical studies have been reported since the first description of the procedure. In the current study, the authors reviewed the literature and evaluated the surgical results, neuropsychological outcome, and complication rate in patients who had undergone stereotactic amygdalotomy for severe aggressive behavioral disorders. The PubMed database was searched using the following terms: "amygdalotomy," "amygdalectomy," "amygdaloidectomy," "psychosurgery," "aggressive disorder," and "behavioral disorder." Clinical series with more than 5 patients undergoing stereotactic amygdalotomy for aggressive or other behavioral disorders were included in this review. The surgical technique, anatomical target, improvement in psychiatric symptomatology, postoperative employment and social rehabilitation, postoperative neurocognitive function, procedure-related complications, and long-term follow-up were evaluated. Thirteen clinical studies met our inclusion criteria. Reported postoperative improvement in aggressive behavior varied between 33 and 100%. Procedure-related complication rates ranged from 0 to 42%, whereas the mortality rate was as high as 3.8%. In the majority of the reviewed clinical series, the performance of stereotactic amygdalotomy did not compromise a patient's learning, language, and intellectual capabilities. The long-term follow-up, although very limited, revealed that initially observed improvement was maintained in most cases. Stereotactic amygdalotomy can be considered a valid surgical treatment option for carefully selected patients with medically refractory aggressive behavioral disorders. Recent advances in imaging and stereotactic navigation can further improve outcome and minimize the complication rate associated with this psychosurgical procedure.

Ischemic necrosis of the tongue in surgical patients with septic shock: a case report.

PubMed

Cho, Jinbeom; Sung, Kiyoung; Lee, Dosang

2016-07-19

As the tongue is a well-vascularized organ, ischemic necrosis of the tongue is a rare disease entity. Critically ill patients with profound shock may experience end-organ hypoperfusion, which might result in tongue necrosis. However, to our best knowledge, there are no reports regarding ischemic necrosis of the tongue in surgical patients with septic shock. Two patients recently developed ischemic necrosis of the tongue in our surgical intensive care unit. Both patients had undergone emergent surgery for ischemic enteritis and developed postoperative septic shock. The first patient responded to critical treatment with a short period of circulatory shock, and the delivered dose of the vasopressor seemed to be acceptable. In contrast, the second patient developed postoperative refractory shock, and high-dose vasopressor treatment was required to maintain adequate tissue perfusion. Both patients developed ischemic necrosis of the tongue and died shortly after its emergence, despite vigorous resuscitation. We suggest that ischemic necrosis of the tongue is an under-reported manifestation of any type of circulatory shock, which may have a complex pathogenic mechanism. Clinicians should be aware of the possibility of ischemic necrosis of the tongue in patients with circulatory shock, even if the patient exhibits clinical improvement, as this awareness may facilitate estimation of their prognosis and preparation for clinical deterioration.

The prevalence and severity of dysphagia in people treated non-surgically for primary head and neck cancer (HNC) is well documented. However, few studies have looked beyond the physiological impairment to explore the lived experience of dysphagia in the post-treatment period of HNC. The current study adopted a person-centred, qualitative approach to describe the experiences of people living with dysphagia in the months and years following non-surgical treatment for HNC. Using maximum variation sampling, 24 participants who had undergone radiotherapy treatment for HNC were recruited. Individual interviews were conducted to explore the impact of dysphagia on participants' everyday lives. The themes identified included: (1) physical changes related to swallowing; (2) emotions evoked by living with dysphagia; (3) altered perceptions and changes in appreciation of food; and (4) personal and lifestyle impacts. The data revealed the breadth and significance of the impact of dysphagia on the lives of people treated curatively for HNC. Assessment and management in the post-treatment period must be sufficiently holistic to address both the changing physical states and the psychosocial needs of people with dysphagia following HNC. Rehabilitation services which focus only on impairment-based management will fail to fully meet the support needs of this clinical population.
