Secondary hyperparathyroidism is a common acquired disorder seen in chronic renal failure. Its pathophysiology is mainly due to hyperphosphatemia and vitamin D deficiency and resistance. When medical treatment fails, subtotal and total parathyroidectomy with autotransplantation are the standard procedures, although both are associated with high recurrence rates. 4 patients experienced persistence and 9 relapse. The first 4 were subjected to reoperation after 6 months for the persistence of symptoms due to the finding of a supernumerary adenomatous gland while the remaining patients at the reoperation showed in 5 cases 2 more glands in over thymic position, and 4 an hyperplasia of the residual glandular tissue. A classic cervicotomy was sufficient to remove the residual parathyroid in patients with persistent hyperparathyroidism. For cases of recurrent hyperparathyroidism it was enough a medial approach and sometimes lateral for the complete excision of the hyperplastic tissue. The advent of the intraoperative technique of parathyroid hormone dosage allowed a better performance of the surgical technique for the last 3 patients undergoing reoperation. After reoperation all patients had immediate regression of clinical symptoms with normalization of serum calcium and PTH levels. On the basis of these considerations, diagnostic imaging has a not negligible role because during the first intervention helps to have an idea of the possible location of the glands and thus to avoid the risk of recurrence and relapse due to ectopic or supernumerary tissue.

Resective surgery is a safe and effective treatment of drug-resistant epilepsy. If surgery has failed reoperation after careful re-evaluation may be a reasonable option. This study was to summarise the risks and benefits of reoperation in patients with epilepsy. This is a retrospective single centre study comprising clinical data, long-term seizure outcome, neuropsychological outcome and postoperative complications of patients, who had undergone a second resective epilepsy surgery from 1989 to 2009. A total of 66 patients with median follow-up of 10.3 years were included into the study. Fifty-one patients (77%) had surgery for temporal lobe epilepsy, the remaining 15 cases for extra-temporal lobe epilepsies. The most frequent histological findings were tumours (n=33, 50%), followed by dysplasia, gliosis (n=11, each) and hippocampus sclerosis (n=9). The main reasons for seizure recurrence were incomplete resection (59.1%) of the putative epileptogenic lesion. After reoperation 46 patients (69.7%) were completely seizure-free International League Against Epilepsy 1 (ILAE 1) at the last available follow-up. The neuropsychological evaluation demonstrated that repeated losses in the same cognitive domain, that is, successive changes from better to worse performance categories, were rare and that those losses after first surgery were followed by improvement rather than decline. However, reoperations lead to an increased rate of permanent neurological deficits (9%), overall surgical complications (9%) and visual field deficits (67%). Reoperation after failed resective epilepsy surgery led to approximately 70% long-time seizure freedom and reasonable neuropsychological outcome. There is an increased risk of permanent postoperative neurological deficits, which should be taken into consideration when counselling for reoperation. Published by the BMJ Publishing Group Limited.

Mandible angle fractures can be repaired in a variety of ways, with no consensus on the outcomes of complications and reoperation rates. To analyze patient, injury, and surgical factors, including approach to the angle and plating technique, associated with postoperative complications, as well as the rate of reoperation with regard to mandible angle fractures. Retrospective cohort study analyzing the surgical outcomes of patients with mandible angle fractures between January 1, 2000, and December 31, 2015, who underwent open reduction and internal fixation. Patients were eligible if they were aged 18 years or older, had 3 or less mandible fractures with 1 involving the mandibular angle, and had adequate follow-up data. Patients with comminuted angle fractures, bilateral angle fractures, and multiple surgical approaches were excluded. A total of 135 patients were included in the study. All procedures were conducted at a single, large academic hospital located in an urban setting. Major complications and reoperation rates. Major complications included in this study were nonunion, malunion, severe malocclusion, severe infection, and exposed hardware. Of 135 patients 113 (83.7%) were men; median age was 29 years (range, 18-82 years). Eighty-seven patients (64.4%) underwent the transcervical approach and 48 patients (35.6%) received the transoral approach. Fifteen (17.2%) patients in the transcervical group and 9 (18.8%) patients in the transoral group experienced major complications (difference, 1%; 95% CI, -8% to 10%). Thirteen (14.9%) patients in the transcervical group and 8 (16.7%) patients in the transoral group underwent reoperations (difference, 2%; 95% CI, -13% to 17%). Active smoking had a significant effect on the rate of major complications (odds ratio, 4.04; 95% CI, 1.07 to 15.34; P = .04). During repair of noncomminuted mandibular angle fractures, both of the commonly used approaches-transcervical and transoral-can be used during treatment with equal

To describe the incidence and outcomes of reoperations for glaucoma in the Tube Versus Trabeculectomy (TVT) Study. Cohort study of patients in a multicenter randomized clinical trial. The TVT Study enrolled 212 patients with medically uncontrolled glaucoma who had previous cataract and/or glaucoma surgery. Randomization assigned 107 patients to surgery with a tube shunt (350 mm(2) Baerveldt glaucoma implant) and 105 patients to trabeculectomy with mitomycin C (0.4 mg/mL for 4 minutes). Data were analyzed from patients who failed their assigned treatment and had additional glaucoma surgery. Outcome measures included intraocular pressure (IOP), use of glaucoma medications, visual acuity, surgical complications, and failure (IOP >21 mm Hg or not reduced by 20%, IOP ≤5 mm Hg, additional glaucoma surgery, or loss of light perception vision). Additional glaucoma surgery was performed in 8 patients in the tube group and 18 patients in the trabeculectomy group in the TVT Study, and the 5-year cumulative reoperation rate was 9% in the tube group and 29% in the trabeculectomy group (P = .025). Follow-up (mean ± SD) after additional glaucoma surgery was 28.0 ± 16.0 months in the tube group and 30.5 ± 20.4 months in the trabeculectomy group (P = .76). At 2 years after a glaucoma reoperation, IOP (mean ± SD) was 15.0 ± 5.5 mm Hg in the tube group and 14.4 ± 6.6 mm Hg in the trabeculectomy group (P = .84). The number of glaucoma medications (mean ± SD) after 2 years of follow-up was 1.1 ± 1.3 in the tube group and 1.4 ± 1.4 in the trabeculectomy group (P = .71). The cumulative probability of failure at 1, 2, 3, and 4 years after additional glaucoma surgery was 0%, 43%, 43%, and 43%, respectively, in the tube group, and 0%, 9%, 20%, and 47% in the trabeculectomy group (P = .28). Reoperations to manage complications were required in 1 patient in the tube group and 5 patients in the trabeculectomy group (P = .63). The rate of reoperation for glaucoma was higher following

An acute infection after arthroscopic shoulder surgery is a rare but serious complication. Previous studies estimating the incidence of infections after arthroscopic surgery have been conducted, but the majority of these had either relatively small study groups or were not specific to shoulder arthroscopic surgery. To investigate the incidence of acute infections after arthroscopic shoulder surgery and compare infection rates by age group, sex, geographic region, and specific procedures. Case series; Level of evidence, 4. A retrospective review of a large insurance company database was performed for all shoulder arthroscopic surgeries performed in the United States between 2004 and 2009 that required additional surgery for infections within 30 days. The data were stratified by sex, age group, and region. Data were also stratified for specific procedures (capsulorrhaphy, treatment for superior labrum anterior-posterior tears, claviculectomy, decompression, and rotator cuff repair) and used to assess the variation in the incidence of infections across different arthroscopic shoulder procedures. Linear regression was used to determine the significance of differences in the data from year to year. χ(2) analysis was used to assess the statistical significance of variations among all groups. Poisson regression analysis with exposure was used to determine significant differences in a pairwise comparison between 2 groups. The total number of arthroscopic shoulder surgeries performed was 165,820, and the number of infections requiring additional surgery was 450, resulting in an overall infection rate of 0.27%. The incidence of infections varied significantly across age groups (P shoulder procedures was 0.27%. The incidence was highest in elderly patients, in the South, and for rotator cuff repair. The incidence was lowest in young patients, in the Midwest, and for capsulorrhaphy. In general, shoulder arthroscopic surgery in this study population had a low rate of

Purpose Perianal lesions are common in Crohn disease, but their clinical course is unpredictable. Nevertheless, predicting the clinical course after surgery for perianal Crohn disease (PCD) is important because repeated operations may decrease patient's quality of life. The aim of this study was to predict the risk of reoperation in patients with PCD. Methods From September 1994 to February 2010, 377 patients with PCD were recruited in twelve major tertiary university-affiliated hospitals and two specialized colorectal hospitals in Korea. Data on the patient's demographics, clinical features, and surgical outcomes were analyzed. Results Among 377 patients, 227 patients were ultimately included in the study. Among the 227 patients, 64 patients underwent at least one reoperation. The median period of reoperation following the first perianal surgery was 94 months. Overall 3-year, 5-year, and 10-year cumulative rates of reoperation-free individuals were 68.8%, 61.2%, and 50.5%, respectively. In multivariate analysis (Cox-regression hazard model), reoperation was significantly correlated with an age of onset less than 20 years (hazard ratio [HR], 1.93; 95% confidence interval [CI], 1.07-3.48; P = 0.03), history of abdominal surgery (HR, 1.99; 95% CI, 1.08-3.64; P = 0.03), and the type of surgery. Among types of surgery, fistulotomy or fistulectomy was associated with a decreased incidence of reoperation in comparison with incision and drainage (HR, 0.19; 95% CI, 0.09-0.42; P < 0.001). Conclusion Young age of onset and a history of abdominal surgery were associated with a high risk of reoperation for PCD, and the risk of reoperation were relatively low in fistulotomy or fistulectomy procedures.

Full Text Available Objectives. To describe reoperative thyroid surgeries in our department. Study Design. Retrospective cross-sectional and descriptive study at the Ouakam Military Hospital in Dakar (Senegal, over a period of eight and a half years. Methods. The study involved all records of patients who had a reoperative thyroidectomy regardless of the indication and time of the second surgery. Parameters evaluated for first and reoperative surgery were time interval between the two surgeries, operative indications, surgical procedures, intraoperative findings, pathological examination, and morbidity. Results. 30 records of patients were selected out of a total of 698 thyroidectomies (4.3%. Thyroid cancers diagnosed on first surgical specimens were the first indications of reoperations (46.67% followed by neck hematoma (20%. Completion thyroidectomy with a prophylactic central lymph nodes dissection was the most performed surgical procedure (43.33% followed by haemostasis (20%. During reoperation, we found active bleeding (20%, textiloma (6.67%, and fourth branchial cleft fistula (3.33%. The morbidity accounted for 10%: lymphorrhea, permanent hypocalcemia, and permanent recurrent nerve palsy, in one case, respectively. There were no statistically significant differences between the morbidity in patients reoperated on and the one for patients operated on once. Conclusion. We did not find an increased risk of postoperative morbidity after reintervention.

Reoperative aortic root replacement is a challenging procedure associated with significant mortality and morbidity. The purpose of this study was to investigate the outcomes of reoperative aortic root replacement when performed in a number of complex clinical settings and to identify risk factors for operative mortality and long-term survival. From 2006 to 2015, 280 consecutive patients at an academic center underwent reoperative aortic root replacement after a variety of previous aortic or cardiac operations. Logistic regression and extended Cox proportional hazards regression analyses were used to determine risk factors for operative mortality and long-term survival, respectively. The mean age of patients was 52.5 ± 14.1 years. Prior operations included proximal aortic replacement in 113 patients, valve surgery in 162 patients, and coronary artery bypass grafting in 46 patients. Concomitant procedures included arch replacement in 135 patients, coronary artery bypass grafting in 68 patients, and mitral valve repair/replacement in 18 patients. Operative mortality was 14.3%. Five-year survival was 74.0%. Univariable analysis did not find previous root replacement, prior proximal aortic surgery, and concomitant arch replacement to be risk factors for operative mortality. In the multivariable analysis, chronic lung disease, prior myocardial infarction, and concomitant mitral valve surgery were risk factors for operative mortality. Age, peripheral artery disease, emergency, and concomitant mitral valve surgery were risk factors for mortality in the late phase. Reoperative aortic root replacement represents complex procedures carrying significant morbidity and mortality. Chronic lung disease, prior myocardial infarction, and concomitant mitral valve surgery were risk factors for operative mortality. Age, peripheral artery disease, emergency, and concomitant mitral valve surgery were risk factors for long-term mortality. Copyright © 2017 The American Association for

To examine a case series of reoperations for deep brain stimulation (DBS) leads in which clinical scenarios revealed suboptimal outcome from a previous operation. Suboptimally placed DBS leads are one potential reason for unsatisfactory results after surgery for Parkinson's disease (PD), essential tremor (ET), or dystonia. In a previous study of patients who experienced suboptimal results, 19 of 41 patients had misplaced leads. Similarly, another report commented that lead placement beyond a 2- to 3-mm window resulted in inadequate clinical benefit, and, in 1 patient, revision improved outcome. The goal of the current study was to perform an unblinded retrospective chart review of DBS patients with unsatisfactory outcomes who presented for reoperation. Patients who had DBS lead replacements after reoperation were assessed with the use of a retrospective review of an institutional review board-approved movement disorders database. Cases of reoperation for suboptimal clinical benefit were included, and cases of replacement of DBS leads caused by infection or hardware malfunction were excluded. Data points studied included age, disease duration, diagnosis, motor outcomes (the Unified Parkinson Disease Rating Scale III in PD, the Tremor Rating Scale in ET, and the Unified Dystonia Rating Scale in dystonia), quality of life (Parkinson's Disease Questionnaire-39 in PD), and the Clinician Global Impression scale. The data from before and after reoperation were examined to determine the estimated impact of repeat surgery. There were 11 patients with PD, 7 with ET, and 4 with dystonia. The average age of the PD group was 52 years, the disease duration was 10 years, and the average vector distance of the location of the active DBS contact was adjusted 5.5 mm. Six patients (54%) with PD had preoperative off medication on DBS Unified Parkinson Disease Rating Scale scores that could be compared with postoperative off medication on DBS scores. The average improvement across this

The effects of chronic corticosteroid therapy on complications, readmission, and reoperation after posterior lumbar fusion (PLF) remain underinvestigated, and were examined to determine differences in outcomes. We analyzed patients undergoing PLF between 2006 and 2013 using the National Surgery Quality Improvement Program database (NSQIP). Patients taking steroids for a chronic condition were compared with those not taking steroids. Multivariable regression identified factors independently associated with complications, readmission, and reoperation. A risk score was calculated for predicting complications. A total of 8492 patients were identified, of whom 353 used steroids. The patients using steroids were older (mean age, 65.4 years vs. 61.0 years; P steroid group. On multivariable regression, steroids were independently associated with overall complications (odds ratio [OR], 1.38; P = 0.044) and infectious complications (OR, 1.65; P < 0.001), but not with medical complications, readmission, or reoperation. Patients with higher risk scores had higher complication rates. The use of corticosteroid therapy is associated with a moderately increased risk of overall complications, but no association was found with readmission or reoperation. Copyright © 2017.

Patients and Methods. Patients scheduled for CRRM with breast reconstruction between 1998 and 2010 completed questionnaires, comprised of SF-36, the Hospital Anxiety and Depression Scale, the Body Image Scale, and the Sexual Activity Questionnaire, preoperatively and two years after CRRM. Data on reoperations was collected from medical charts. Results. A total of 80 women participated, with a response rate of 61 (76% preoperatively and 57 (71% at the two-year follow-up. At the two-year assessment, 44 (55% patients had undergone ≥1 reoperation (reoperation group, whereas 36 (45% had not (no reoperation group. No statistically significant differences between the groups were found for HRQoL, sexuality, anxiety, or depression. A higher proportion of patients in the “reoperation group” reported being dissatisfied with their bodies (81% versus 48%, p=0.01. Conclusion. The results suggest associations between reoperation following CRRM with breast reconstruction and body image problems. Special attention should be paid to body image problems among women who are subject to reoperations after CRRM.

Crohn's disease (CD) is a chronic inflammatory bowel disease known to carry a high risk of disabling and many times requiring surgical interventions. This article describes a decision-tree based approach that defines the CD patients' risk or undergoing disabling events, surgical interventions and reoperations, based on clinical and demographic variables. This multicentric study involved 1547 CD patients retrospectively enrolled and divided into two cohorts: a derivation one (80%) and a validation one (20%). Decision trees were built upon applying the CHAIRT algorithm for the selection of variables. Three-level decision trees were built for the risk of disabling and reoperation, whereas the risk of surgery was described in a two-level one. A receiver operating characteristic (ROC) analysis was performed, and the area under the curves (AUC) Was higher than 70% for all outcomes. The defined risk cut-off values show usefulness for the assessed outcomes: risk levels above 75% for disabling had an odds test positivity of 4.06 [3.50-4.71], whereas risk levels below 34% and 19% excluded surgery and reoperation with an odds test negativity of 0.15 [0.09-0.25] and 0.50 [0.24-1.01], respectively. Overall, patients with B2 or B3 phenotype had a higher proportion of disabling disease and surgery, while patients with later introduction of pharmacological therapeutic (1 months after initial surgery) had a higher proportion of reoperation. The decision-tree based approach used in this study, with demographic and clinical variables, has shown to be a valid and useful approach to depict such risks of disabling, surgery and reoperation.

OBJECTIVE Although reoperation and readmission have been used as quality metrics, there are limited data evaluating the rate of, reasons for, and predictors of reoperation and readmission after microsurgical clipping of unruptured aneurysms. METHODS Adult patients who underwent craniotomy for clipping of an unruptured aneurysm electively were extracted from the prospective National Surgical Quality Improvement Program registry (2011-2014). Multivariable logistic regression and recursive partitioning analysis evaluated the independent predictors of nonroutine hospital discharge, unplanned 30-day reoperation, and readmission. Predictors screened included patient age, sex, comorbidities, American Society of Anesthesiologists (ASA) classification, functional status, aneurysm location, preoperative laboratory values, operative time, and postoperative complications. RESULTS Among the 460 patients evaluated, 4.2% underwent any reoperation at a median of 7 days (interquartile range [IQR] 2-17 days) postoperatively, and 1.1% required a cranial reoperation. The most common reoperation was ventricular shunt placement (23.5%); other reoperations were tracheostomy, craniotomy for hematoma evacuation, and decompressive hemicraniectomy. Independent predictors of any unplanned reoperation were age greater than 51 years and longer operative time (p ≤ 0.04). Readmission occurred in 6.3% of patients at a median of 6 days (IQR 5-13 days) after discharge from the surgical hospitalization; 59.1% of patients were readmitted within 1 week and 86.4% within 2 weeks of discharge. The most common reason for readmission was seizure (26.7%); other causes of readmission included hydrocephalus, cerebrovascular accidents, and headache. Unplanned readmission was independently associated with age greater than 65 years, Class II or III obesity (body mass index > 35 kg/m 2 ), preoperative hyponatremia, and preoperative anemia (p ≤ 0.04). Readmission was not associated with operative time

Epstein, Nancy E.

2018-01-01

Background: Utilizing the spine literature, we compared the complication and reoperation rates for laminectomy alone vs. instrumented fusions including minimally invasive (MI) transforaminal lumbar interbody fusion (TLIF) for the surgical management of multilevel degenerative lumbar disease with/without degenerative spondylolisthesis (DS). Methods: Epstein compared complication and reoperation rates over 2 years for 137 patients undergoing laminectomy alone undergoing 2-3 level (58 patients) and 4-6 level (79 patients) Procedures for lumbar stenosis with/without DS. Results showed no new postoperative neurological deficits, no infections, no surgery for adjacent segment disease (ASD), 4 patients (2.9%) who developed intraoperative cerebrospinal fluid (CSF) fistulas, no readmissions, and just 1 reopereation for a (postoperative day 7). These rates were compared to other literature for lumbar laminectomies vs. fusions (e.g. particularly MI TLIF) addressing pathology comparable to that listed above. Results: Some studies in the literature revealed an average 4.8% complication rate for laminectomy alone vs. 8.3% for decompressions/fusion; at 5 postoperative years, reoperation rates were 10.6% vs. 18.4%, respectively. Specifically, the MI TLIF literature complication rates ranged from 7.7% to 23.0% and included up to an 8.3% incidence of wound infections, 6.1% durotomies, 9.7% permanent neurological deficits, and 20.2% incidence of new sensory deficits. Reoperation rates (1.6–6%) for MI TLIF addressed instrumentation failure (2.3%), cage migration (1.26–2.4%), cage extrusions (0.8%), and misplaced screws (1.6%). The learning curve (e.g. number of cases required by a surgeon to become proficient) for MI TLIF was the first 33-44 cases. Furthermore, hospital costs for lumbar fusions were 2.6 fold greater than those for laminectomy alone, with overall neurosurgeon reimbursement quoted in one study as high as $142,075 per year. Conclusions: The spinal literature revealed

The aim of t his study was to r eview our institutional 2 0 -year experience of surgical reoperative valve replacement in patients with PVE. Methods: A retrospective study was performed on 84 patients (mean age, 54.8±12.7 years; 51 males who were diagnosed with PVE and underwent reoperative valve replacement from January 1995 to December 2016. Results: PVE was found in 1 valve in 61 cases (72.6%, and in 2 or more valves in 23 cases (27.4%. The median follow-up duration was 47.3 months (range, 0 to 250 months. Postoperative complications occurred in 39 patients (46.4%. Reinfection occurred in 6 cases, all within 1 year. The freedom from reinfection rate at 5 years was 91.0%±3.5%.

The authors' clinical experience is presented of non-structural valvular dysfunction of the prosthetic aortic valve caused by pannus ingrowth during the late postoperative period after previous heart valve surgery. Between January 1999 and April 2012, at the authors' institution, a total of 33 patients underwent reoperation for increased mean pressure gradient of the prosthetic aortic valve. All patients were shown to have pannus ingrowth. The mean interval from the previous operation was 16.7 +/- 4.3 years, and the most common etiology for the previous aortic valve replacement (AVR) was rheumatic valve disease. The mean effective orifice area index (EOAI) of the previous prosthetic valve was 0.97 +/- 0.11 cm2/m2, and the mean pressure gradient on the aortic prosthesis before reoperation was 39.1 +/- 10.7 mmHg. Two patients (6.1%) died in-hospital, and late death occurred in six patients (18.2%). At the first operation, 30 patients underwent mitral or tricuspid valve surgery as a concomitant procedure. Among these operations, mitral valve replacement (MVR) was combined in 24 of all 26 patients with rheumatic valve disease. Four patients underwent pannus removal only while the prosthetic aortic valve was left in place. The mean EOAI after reoperation was significantly increased to 1.16 +/- 0.16 cm2/m2 (p pannus ingrowth was shown in patients with a small EOAI of the prosthetic aortic valve and combined MVR for rheumatic disease. As reoperation for pannus overgrowth showed good clinical outcomes, an aggressive resection of pannus and repeated AVR should be considered in symptomatic patients to avoid the complications of other cardiac diseases.

Full Text Available Abstract Background Selective serotonin reuptake inhibitors (SSRI decrease platelet-function, which suggests that SSRI use may increase the risk of post-surgical bleeding. Few studies have investigated this potential association. Methods We conducted a population-based study of the risk of re-operation due to post-surgical bleeding within two weeks of primary surgery among Danish women with primary breast cancer. Patients were categorised according to their use of SSRI: never users, current users (SSRI prescription within 30 days of initial breast cancer surgery, and former users (SSRI prescription more than 30 days before initial breast cancer surgery. We calculated the risk of re-operation due to post-surgical bleeding within 14 days of initial surgery, and the relative risk (RR of re-operation comparing SSRI users with never users of SSRI adjusting for potential confounders. Results 389 of 14,464 women (2.7% were re-operated. 1592 (11% had a history of SSRI use. Risk of re-operation was 2.6% among never users, 7.0% among current SSRI users, and 2.7% among former users. Current users thus had an increased risk of re-operation due to post-operative bleeding (adjusted relative risk = 2.3; 95% confidence interval (CI = 1.4, 3.9 compared with never users. There was no increased risk of re-operation associated with former use of SSRI (RR = 0.93, 95% CI = 0.66, 1.3. Conclusions Current use of SSRI is associated with an increased risk of re-operation due to bleeding after surgery for breast cancer.

Diabetes mellitus confers an increased risk of hip fractures. There is a limited knowledge of how the outcome after a hip fracture in patients with diabetes affect Health Related Quality of Life (HRQoL). The primary aim of this study was to evaluate HRQoL. Secondary aims were reoperation rate, complications and functions in patients with diabetes followed for 2 years after a hip fracture. Out of 2133 patients diabetes was present in 234 patients (11%). Main outcome measurements were HRQoL evaluated with EuroQoL 5-Dindex score, reoperation rate, surgical and medical complications, function as walking ability, daily activities, living condition and pain. Preoperatively, patients with diabetes mellitus had more pain (p=0.044), co-morbidities, reduced health status (p=0.001) and more often used a walking frame (p=0.014) than patients without diabetes, whereas Katz ADL index, cognition and body mass index did not differ. There was no difference in fracture type, surgical method or reoperation between the two groups or between patients with insulin treated or oral treated diabetes. The EQ-5Dindex score decreased from 0.64 at admission to 0.45 at 4 months, 0.49 at 12 months and 0.51 at 24 months with similar results for patients with and without diabetes. During the first postoperative year there was not more medical complications among patients with diabetes, however cardiac (p=0.023) and renal failure (p=0.032) were more frequent in patients with diabetes at 24 months. Patients with diabetes more often had severe hip pain at 4 months (p=0.031). At 12 months more diabetic patients were living independently (p=0.034). There was no difference in walking ability, ADL and living condition between the groups at 24 months. The findings of this study indicate that patients with diabetes mellitus had more pain, co-morbidities, reduced health status preoperatively than patients without diabetes. Hip fracture patients with diabetes mellitus have more hip pain at 4 months. Cardiac

This study aims to describe laparoscopic reoperation (LSR) and compare its outcomes with transabdominal reoperation (TAR) for treating Hirschsprung's disease (HD). Eighteen patients with HD underwent reoperation for recurring constipation due to residual aganglionosis and transition zone pathology after an initial transanal procedure (LSR, n=10; TAR, n=8). Preoperative, operative and postoperative data were collected through patient follow-ups ranging from 13 to 75months to compare operative characteristics and postoperative outcomes between the two groups. Ten patients underwent laparoscopic reoperation in our institution without major complications. On average, blood loss was significantly lower in the LSR group (mean±standard deviation, 83±32.7mL) than in the TAR group (185±69mL) (P=0.001). The LSR group had a shorter hospitalization time (12±2days) than the TAR group (15±2.1days) (P=0.02). There was no statistically significant difference in incidence of postoperative complications between the two groups. LSR is safe and technically feasible in HD for recurring constipation due to residual aganglionosis and transition zone pathology, when initial transanal procedure fails. Although RA and TZP can be cured by reoperation, great efforts should be made to diminish the necessity of reoperation. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background The overall rate of operations after recurrent lumbar disc herniation has been shown to be 3–11%. However, little is known about the rate of residives. Thus the aim of this study was to explore the cumulative rates of re-operations and especially residive disc herniations at the same side and level as the primary disc herniation after first lumbar disc herniation surgery and the factors that influence the risk of re-operations over a five year follow-up study. Methods 166 virgin lumbar disc herniation patients (mean age 42 years, 57% males were studied. Data on patients' initial disc operations and type and timing of re-operations during the follow-up were collected from patient files. Back and leg pain on visual analog scale and employment status were collected by questionnaires. Results The cumulative rate of re-operations for lumbar disc herniation was 10.2% (95% Cl 6.0 to 15.1. The rate of residives at initial site was 7.4% (95% Cl 3.7 to 11.3 and rate of lumbar disc herniations at other sites was 3.1% (95% Cl 0.6 to 6.2. The occurrence of residive lumbar disc herniations was evenly distributed across the 5 years. Neither age, gender, preoperative symptoms, physical activity nor employment had effect on the probability of re-operation. Conclusion Seven percent of the lumbar disc patients had a residive lumbar disc operation within five years of their first operation. No specific factors influencing the risk for re-operation were found.

Aim: To investigate whether magnetic resonance imaging (MRI) changes the management of patients with screen-detected invasive lobular carcinoma (ILC). Materials and methods: A retrospective, controlled, single-centre analysis of 138 cases of screen-detected ILC was performed. All patients were assessed by a single multidisciplinary team as to whether preoperative MRI altered the initial management decision or reduced re-operation rates. Results: Forty-three percent of patients had preoperative MRI. MRI guided surgical management in 40.7% patients. Primary mastectomy rates were not significantly different between the MRI and non-MRI groups (32% and 30% respectively, p=0.71). The MRI group had a lower secondary surgery rate (6.8% versus 15.2%); however, the results did not reach statistical significance, and there were no unnecessary mastectomies. Conclusion: MRI can be used appropriately to guide primary surgery in screen-detected ILC cases and affects the initial management decision in 40.7% of patients. It does not significantly affect the overall mastectomy rate or re-operation rates, but reduces the likelihood of the latter. As a result of this review, the authors' local policy for the use of MRI in screen-detected ILC patients has been modified. For patients undergoing mastectomy for ILC, MRI is no longer performed routinely to search for contralateral malignancy as this has no proven added benefit. - Highlights: • Breast magnetic resonance imaging (MRI) allows more accurate tumour assessment and detects additional foci of disease in invasive lobular carcinoma (ILC). • Over the study's 3 year time frame, MRI guided surgical management of 40.7% screen-detected ILC patients scanned. • No statistically significant difference in mastectomy rates between MRI and non MRI groups. • Observed lower re-operation rate (6.8%-v-15.2%) in MRI group not statistically significant. • No MRI benefit for contralateral disease detection in ILC patients for

Tricuspid valve insufficiency (TI) following cardiovascular surgery causes right-side heart failure and hepatic failure, which affect patient prognosis. Moreover, the benefits of reoperation for severe tricuspid insufficiency remain unclear. We investigated the surgical outcomes of reoperation in TI. From the Japan Cardiovascular Surgery Database (JACVSD), we extracted cases who underwent surgery for TI following cardiac surgery between January 2006 and December 2011. We analysed the surgical outcomes, specifically comparing tricuspid valve replacement (TVR) and tricuspid valve plasty (TVP). Of the 167 722 surgical JACVSD registered cases, reoperative TI surgery occurred in 1771 cases, with 193 TVR cases and 1578 TVP cases. The age and sex distribution was 684 males and 1087 females, with an average age of 66.5 ± 10.8 years. The overall hospital mortality was 6.8% and was significantly higher in the TVR group than in the TVP group (14.5 vs 5.8%, respectively; P tricuspid surgery were unsatisfactory. Although TVR is a last resort for non-repairable tricuspid lesions, it carries a significant risk of surgical mortality. Improving the patient's preoperative status and opting for TVP over TVR is necessary to improve the results of reoperative tricuspid surgery. © The Author 2014.

Laparoscopic techniques can be used to treat patients whose antireflux surgery has failed. Case series. Two academic medical centers. Forty-six consecutive patients, of whom 21 were male and 25 were female (mean age, 55.6 years; range, 15-80 years). Previous antireflux procedures were laparoscopic (21 patients), laparotomy (21 patients), thoracotomy (3 patients), and thoracoscopy (1 patient). The cause of failure, operative and postoperative morbidity, and the level of follow-up satisfaction were determined for all patients. The causes of failure were hiatal herniation (31 patients [67%]), fundoplication breakdown (20 patients [43%]), fundoplication slippage (9 patients [20%]), tight fundoplication (5 patients [11%]), misdiagnosed achalasia (2 patients [4%]), and displaced Angelchik prosthesis (2 patients [4%]). Twenty-two patients (48%) had more than 1 cause. Laparoscopic reoperative procedures were Nissen fundoplication (n = 22), Toupet fundoplication (n = 13), paraesophageal hernia repair (n = 4), Dor procedure (n = 2), Angelchik prosthesis removal (n = 2), Heller myotomy (n = 2), and the takedown of a wrap (n = 1). In addition, 18 patients required crural repair and 13 required paraesophageal hernia repair. The mean +/- SEM duration of surgery was 3.5+/-1.1 hours. Operative complications were fundus tear (n = 8), significant bleeding (n = 4), bougie perforation (n = 1), small bowel enterotomy (n = 1), and tension pneumothorax (n = 1). The conversion rate (from laparoscopic to an open procedure) was 20% overall (9 patients) but 0% in the last 10 patients. Mortality was 0%. The mean +/- SEM hospital stay was 2.3+/-0.9 days for operations completed laparoscopically. Follow-up was possible in 35 patients (76%) at 17.2+/-11.8 months. The well-being score (1 best; 10, worst) was 8.6+/-2.1 before and 2.9+/-2.4 after surgery (Papproach may be used successfully to treat patients with failed antireflux operations.

High-performing health care organizations differentiate themselves by focusing on continuous process improvement initiatives aimed at enhancing patient outcomes. Reoperation for bleeding is an event associated with considerable morbidity risk. Hence, our primary objective was to develop and implement a formal operative checklist to reduce technical reasons for postoperative bleeding. From January 1, 2011, through June 30, 2012, 5812 cardiac surgical procedures were performed at Cleveland Clinic (Cleveland, OH). A multidisciplinary team developed a simple, easy-to-perform hemostasis checklist based on the most common sites of bleeding. An extensive educational in-service was performed before limited, then universal, checklist implementation. Geometric charts were used to track the number of cases between consecutive reoperations for bleeding. We compared these before (phase 0) and after the first limited implementation phase (phase 1) and the universal implementation phase (phase 2) of the checklist. The average number of cases between consecutive reoperations for bleeding increased from 32 in phase 0 to 53 in both phase 1 (P = .002) and phase 2 (P = .01). A substantial reduction in reoperation for bleeding cases followed implementation of a formalized hemostasis checklist. Our findings underscore the important influence of memory aids that focus attention on surgical techniques to improve patient outcomes in a complex, operative work environment.

Obesity has been associated with increased risk for postoperative CSF leak in patients with benign cranial nerve tumors. Other measures of postoperative morbidity associated with obesity have not been well characterized. Patients enrolled in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) from 2007 to 2013 with a diagnosis code of a benign neoplasm of a cranial nerve were included. The primary outcome of postoperative morbidity was analyzed as well as secondary outcomes of readmission and reoperation. The main covariate of interest was body mass index (BMI). A total of 561 patients underwent surgery for a benign cranial nerve neoplasm between 2007 and 2013. Readmission data, available for 2012-2013(n=353), revealed hydrocephalus, facial nerve injury, or CSF leak requiring readmission or reoperation occurred in 0.85%, 1.42%, and 3.12%, respectively. Composite morbidity included wound complications, infection, respiratory insufficiency, transfusion requirement, stroke, venous thromboembolism, coma and cardiac arrest. On multivariable analysis patients with class I (BMI 30-34.9) and II (BMI 35-39.9) obesity showed trends towards increasing return to operating room, though not significant, but there was no trend for composite complications in class I and II obesity patients. However, class III obesity, BMI≥40, was associated with increased odds of composite morbidity (OR 4.40, 95% CI 1.24-15.88) and return to the operating room (OR 5.97, 95% CI 1.20-29.6) relative to patients with a normal BMI, 18.5-25. Obesity is an independent and important risk factor for composite morbidity in resection of benign cranial nerve neoplasms, and as such, merits discussion during preoperative counseling.

Full Text Available ABSTRACT OBJECTIVE: To evaluate the prevalence of rotator cuff tears and describe the profile of reoperated patients, causes of repeated tendon tears, tear evolution and range of times between surgical procedures. METHOD: This was a cross-sectional study involving 604 surgical procedures performed at two regional referral hospitals between January 2006 and December 2012. After approval by the ethics committee, data describing the patients' epidemiological profile were gathered at a single time, using Cofield's classification to measure the extent of the tears, all of which underwent arthroscopic surgery. The data were entered into Epi Info 3.5.3 and were analyzed using SPSS version 18.0. RESULTS: Among the 604 surgical procedures, females were affected in more cases (351; 58.1%. When the dominant limb was the right limb, it was affected in 90% of the cases (p < 0.05. The supraspinatus tendon was affected in 574 cases (95% and the tears were of medium size in 300 cases (49.7%. Eighteen reoperations were performed (2.98% and the upper right limb was the most affected (66.6%. The cause was non-traumatic in 12 patients. The repeated tears were mostly smaller (44%, and the length of time between the two surgical procedures ranged from 6 to 298 weeks. CONCLUSION: Female gender, smaller extent in the second procedure and non-traumatic cause were found in most of the cases analyzed.

The optimal management of chronic subdural hematomas remains a challenge. Twist drill craniotomy or burr hole trephination are considered optimal initial treatments, but the reoperation rate for hematoma recurrence and other complications is still high. Therefore, evaluation of possible risk factors for initial treatment failure is crucial. In this context, we performed a study to define a possible subpopulation that may benefit from a more invasive initial treatment regime. We retrospectively reviewed the medical charts of 193 patients with 250 chronic subdural hematomas who had undergone burr hole trephination as first-line therapy in our institution between January 2005 and October 2012. To identify risk factors for reoperation, a multivariable logistic regression analysis was performed with reoperation as the dependent variable. Surgical complications, including acute rebleeding, infection and chronic hematoma recurrence, were analyzed separately using a logistic regression model. The mean age of the cohort was 71.4 years. The male/female ratio was 137:56. Reoperation was necessary in 56 cases (29%) for recurrent hematomas and surgical complications. Predictors for reoperation for surgical complications were midline shift (odds ratio [OR] (per mm) 1.16, 95% confidence interval [CI]: 1.05-1.29, p=0.006), arterial hypertension (OR 5.44, 95% CI: 1.45-20.41, p=0.012) and bilateral hematomas (OR 4.22, 95% CI: 1.22-14.58, p=0.023). There was a trend toward a higher risk of surgically-relevant hematoma recurrence in patients with prior treatment with vitamin K antagonists (OR 1.76, 95% CI: 0.75-4.13, p=0.191). Burr hole trephination is the therapy of choice in most chronic subdural hematomas, but the rate of recurrent hematomas is high. Every hematoma should be treated individually especially in relation to midline-shift and pre-existing conditions. Further prospective studies evaluating types of treatment and hematoma density are needed. Copyright © 2015 Elsevier B

Laparoscopic Heller myotomy with antireflux procedure seems the procedure of choice in the treatment of patients with esophageal achalasia. Persistent or recurrent symptoms occur in 10% to 20% of patients. Few reports on reoperation after failed Heller myotomy have been published. No author has reported the realization of a total fundoplication in these patient groups. The aim of this study is to evaluate the efficacy of laparoscopic reoperation with the realization of a total fundoplication after failed Heller myotomy for esophageal achalasia. From 1992 to December 2007, 5 out of a series of 242 patients (2.1%), along with 2 patients operated elsewhere, underwent laparoscopic reintervention for failed Heller myotomy. Symptoms leading to reoperation included persistent dysphagia in 3 patients, recurrent dysphagia in another 3, and heartburn in 1 patient. Mean time from the first to the second operation was 49.7 months (range, 4-180 months). Always, the intervention was completed via a laparoscopic approach and a Nissen-Rossetti fundoplication was realized or left in place after a complete Heller myotomy. Mean operative time was 160 minutes (range, 60-245 minutes). Mean postoperative hospital stay was 3.1 +/- 1.5 days. No major morbidity or mortality occurred. At a mean follow-up of 16.1 months, reoperation must be considered successful in 5 out of 7 patients (71.4%). The dysphagia DeMeester score fell from 2.71 +/- 0.22 to 0.91 +/- 0.38 postoperatively. The regurgitation score changed from 2.45 +/- 0.34 to 0.68 +/- 0.23. Laparoscopic reoperation for failed Heller myotomy with the realization of a total fundoplication is safe and is associated with good long-term results if performed by an experienced surgeon in a center with a long tradition of esophageal surgery.

Full Text Available Valvular and coronary artery disease are among the most important causes of disability and death in the world and Iran as well. Every year, half a million death because of these diseases is reported in United State. The incidence of degenerative and valvular diseases of heart is increasing. Considering the industrialization of our country, the incidence of these kind of problems are increasing as well. In this study, there is an attempt to recognize the causes of cardiac surgery. We conducted a retrospective study in 915 cardiac surgery patients (630 CABG and 285 valve replacement from 1374 to 1377. In CABG patients, there were 46 cases of reoperation (78.3 percent male 21.7 percent female. The most reoperations for bleeding was less than 24 hours in 90.3 percent. In valvular patients the causes of reoperation were: A Valvular complications (female/male=3/1, B Non valvular complications (female/male=1/3. The most common nonvalvular complication was bleeding (66.6 percent. The most common valvular complication was bioprosthetic valve degeneration. The meantime between two operation in valvular complications was 11.8 years. In all cases (915 the incidence of bleeding was 3.8 percent, mediastinitis 0.8 percent, cardiac tamponade 0.8 percent and GI bleeding 0.5 percent.

Radiation therapy is often advocated for residual or recurrent craniopharyngioma following surgical resection to prevent local recurrence. However, radiation therapy is not always effective and may render tumors more difficult to remove. If this is the case, patients may benefit more from reoperation if gross total resection can be achieved. Nevertheless, there is little data on the impact of radiation on reoperations for craniopharyngioma. In this study, we sought to analyze whether a history of previous radiation therapy (RT) affected extent of resection in patients with recurrent craniopharyngiomas subsequently treated with reoperation via endoscopic endonasal approach (EEA). The authors reviewed a prospectively acquired database of EEA reoperations of craniopharyngiomas over 13 years at Weill Cornell, NewYork-Presbyterian Hospital. All procedures were performed by the senior author. The operations were separated into two groups based on whether the patient had surgery alone (group A) or surgery and RT (group B) prior to recurrence. A total of 24 patients (16 male, 8 female) who underwent surgery for recurrent craniopharyngioma were identified. The average time to recurrence was 7.64 ± 4.34 months (range 3-16 months) for group A and 16.62 ± 12.1 months (range 6-45 months) for group B (p < 0.05). The average tumor size at recurrence was smaller in group A (1.85 ± 0.72 cm; range 0.5-3.2) than group B (2.59 ± 0.91 cm; range 1.5-4.6; p = 0.00017). Gross total resection (GTR) was achieved in 91% (10/11) of patients in group A and 54% (7/13) of patients in group B (p = 0.047). There was a near significant trend for higher average Karnofsky performance status (KPS) score at last follow-up for group A (83 ± 10.6) compared with group B (70 ± 16.3, p = 0.056). While RT for residual or recurrent craniopharyngioma may delay time to recurrence, ability to achieve GTR with additional surgery is reduced. In the case of

The aim of this study was to characterize mortality and aortic valve replacement after valve-sparing aortic root replacement (V-SARR) in a multicentre cohort. Between 1994 and 2014, 1015 patients had V-SARR with (n = 288, 28%) or without cusp/commissure repair (n = 727, 72%) at the centres of Lübeck (n = 343, 34%), Stuttgart (n = 346, 34%), Hamburg (n = 109, 11%) and Freiburg (n = 217, 21%), Germany. Comparative survival of an age- and gender-matched general population was calculated. Log-rank tests and multiple logistic regression were used to identify risk factors. The mean follow-up was 5.2 ± 3.9 years. Cumulative follow-up comprised 2933 patient-years. Early survival was 98%. NYHA status and aneurysm size were predictive of death during mid-term follow-up (P = 0.025). Freedom from aortic valve replacement was 90% at 8 years, with the type of V-SARR (root remodelling, David II) being a risk factor (P = 0.015). Bicuspid aortic valve (P = 0.26) and initial valve function (P = 0.4) did not impact reoperation. The need of additional valve repair (cusps/commissures) was not linked to reoperation: freedom from aortic valve replacement at 8 years was 84% if cusp repair was performed versus 90% if V-SARR alone was performed (P = 0.218). Marfan syndrome had no impact on survival or on aortic valve replacement. Mid-term survival of patients after V-SARR is comparable with that of a matched general population. The regurgitant bicuspid aortic valve is a favourable substrate for V-SARR. Prophylactic surgery should be performed before symptoms or large aneurysms are present to achieve optimal mid-term outcomes. © The Author 2015.

Due to the 2011 Great East Japan Earthquake, Japan Materials Testing Reactor (JMTR), as a light-water-moderated cooling type irradiation test reactor, had to conduct the soundness confirmation of the reactor facilities after earthquake (equipment inspection, and earthquake response analysis). JMTR has been working on soundness confirmation with the aim of reoperation in November 2011. However, in order to perform the detailed investigation on the equipment and machinery, such as the repair of partial deformation of the roof truss of reactor building block, change in operation plan was applied again. In the future, the authors will accurately judge the social situation after the Great East Japan Earthquake, and plan the reoperation under safe and stable state, aiming at the world top class operation rate. In addition, our efforts will be directed to the improvement of the facilities by use of external funds based on expanded utilization, and the continuous aggressive activities aiming for JMTR becoming the international hub.

The study aim was to determine the safety and benefits of minimally invasive mitral valve surgery without aortic cross-clamping for mitral valve surgery after previous cardiac surgery. Between January 2006 and August 2008, a total of 90 consecutive patients (38 females, 52 males; mean age 66 +/- 9 years) underwent minimally invasive mitral valve surgery after having undergone previous cardiac surgery. Of these patients, 80 (89%) underwent mitral valve replacement and 10 (11%) mitral valve repair utilizing a small (5 cm) right lateral thoracotomy along the 4th or 5th intercostal space under fibrillatory arrest (mean temperature 28 +/- 2 degrees C). The predicted mortality, calculated using the Society of Thoracic Surgeons (STS) algorithm, was compared to the observed mortality. The mean ejection fraction was 45 +/- 13%, mean NYHA class 3 +/- 1, while 66 patients (73%) had previous coronary artery bypass grafting and 37 (41%) had previous valve surgery. Twenty-six patients (29%) underwent non-elective surgery. Cardiopulmonary bypass was instituted through axillary (n = 19), femoral (n = 70) or direct use aortic (n = 1) cannulation. Operative mortality was 2% (2/90), lower than the STS-predicted mortality of 7%. Three patients (3%) developed acute renal failure postoperatively, one patient (1%) required new-onset hemodialysis, and one (1%) developed postoperative stroke. No patients developed postoperative myocardial infarction. The mean postoperative packed red blood cell transfusion requirement at 48 h was 2 +/- 3 units. Minimally invasive right thoracotomy without aortic cross-clamping is an excellent alternative to conventional redo-sternotomy for reoperative mitral valve surgery. The present study confirmed that this technique is safe and effective in reducing operative mortality in high-risk patients undergoing reoperative cardiac surgery.

Not long ago, laparoscopic adjustable gastric banding (LAGB) was considered a safe and effective treatment of morbid obesity; however, long-term outcomes revealed significant complication and failure rates. We hypothesized that LAGB has higher rates of weight loss failure, reoperation, and overall failure compared to laparoscopic gastric bypass (LRYGB) at long-term follow-up. A matched case-control study was performed. Patients who underwent primary LAGB or LRYGB at a university hospital between 2004 and 2011 were propensity matched for age, gender, race, body mass index (BMI), and weight-related co-morbidities. Outcomes included demographics, percent excess weight loss (% EWL) and reoperation, weight loss failure (failure (procedure-related reoperation and/or failure at 3 years (75 vs. 10.5%, P failure rates were higher after LAGB. The most common complication after LAGB was pouch/esophageal enlargement (9.7%) and after LRYGB was internal hernia (4.8%). LAGB patients had higher morbidity (19 vs. 12.7%, P = 0.04) but similar procedure-related mortality (0 vs. 0.4%). LAGB has significantly higher rates of weight loss failure compared to LRYGB with similar rates of procedure-related reoperation. Overall failure rates are higher after LAGB. These data suggest the long-term effectiveness of LAGB might be limited.

Recurrent symptoms of sciatica after previous surgical intervention is a relatively common and troublesome clinical problem. Percutaneous endoscopic lumbar decompression has been proved to be an effective method for recurrent lumbar disc herniation. However, the prognostic factors and outcomes of percutaneous endoscopic lumbar reoperation (PELR) for recurrent sciatica symptoms were still unknown. The purpose of this study was to evaluate the outcomes and prognostic factors of patients who underwent PELR for recurrent sciatica symptoms. From 2009 to 2015, 94 patients who underwent PELR for recurrent sciatica symptoms were enrolled. The primary surgeries include transforaminal lumbar interbody fusion (n = 16), microendoscopic discectomy (n = 31), percutaneous endoscopic lumbar decompression (PELD, n = 17), and open discectomy (n = 30). The mean follow-up period was 36 months, and 86 (91.5%) patients had obtained at least 24 months' follow-up. Of the 94 patients with adequate follow-up, 51 (54.3%) exhibited excellent improvement, 23 (24.5%) had good improvement, and 7 (7.4%) had fair improvement according to modified Macnab criteria. The average re-recurrence rate was 9.6%, with no difference among the different primary surgery groups (PELD, 3/17; microendoscopic discectomy, 2/31; open discectomy, 3/30; transforaminal lumbar interbody fusion, 1/16). There was a trend toward greater rates of symptom recurrence in the primary group of PELD who underwent percutaneous endoscopic lumbar reoperation compared with other groups, but this did not reach statistical significance (P > 0.05). Multivariate analysis suggested that age, body mass index, and surgeon level was independent prognostic factors. Obesity (hazard ratio 13.98, 95% confidence interval 3.394-57.57; P sciatica symptoms regardless of different primary operation type. Obesity, inferior surgeon level, and patient age older than 40 years were associated with a worse prognosis. Obesity was also a strong and

To describe procedure-specific types, rates, and risk factors for postdischarge (PD) complications occurring within 30 days after 21 groups of inpatient general surgery procedures. Retrospective cohort study. American College of Surgeons National Surgical Quality Improvement Program 2005 through 2010 Participant Use Data Files. A total of 551,510 adult patients who underwent one of 21 groups of general surgery procedures in the inpatient setting. Postdischarge complications, reoperation, and mortality. Of 551,510 patients (mean age, 54.6 years), 16.7% experienced a complication; 41.5% occurred PD. Of the PD complications, 75.0% occurred within 14 days PD. Proctectomy (14.5%), enteric fistula repair (12.6%), and pancreatic procedures (11.4%) had the highest PD complication rates. Breast, bariatric, and ventral hernia repair procedures had the highest proportions of complications that occurred PD (78.7%, 69.4%, and 62.0%, respectively). For all procedures, surgical site complications, infections, and thromboembolic events were the most common. Occurrence of an inpatient complication increased the likelihood of a PD complication (12.5% vs 6.2% without an inpatient complication; P surgery; those whose PD complication was preceded by an inpatient complication had the highest rates of reoperation (33.7%) and death (24.7%) (all P < .001). After adjustment, PD complications were associated with procedure type, American Society of Anesthesiologists class higher than 3, and steroid use. The PD complication rates vary by procedure, are commonly surgical site related, and are associated with mortality. Fastidious, procedure-specific patient triage at discharge as well as expedited patient follow-up could improve PD outcomes.

To compare radiographic failure and re-operation rates of anatomical coracoclavicular (CC) ligament reconstructional techniques with non-anatomical techniques after chronic high grade acromioclavicular (AC) joint injuries. We reviewed chronic AC joint reconstructions within a region-wide healthcare system to identify surgical technique, complications, radiographic failure and re-operations. Procedures fell into four categories: (1) modified Weaver-Dunn, (2) allograft fixed through coracoid and clavicular tunnels, (3) allograft loop coracoclavicular fixation, and (4) combined allograft loop and synthetic cortical button fixation. Among 167 patients (mean age 38.1 years, (standard deviation (sd) 14.7) treated at least a four week interval after injury, 154 had post-operative radiographs available for analysis. Radiographic failure occurred in 33/154 cases (21.4%), with the lowest rate in Technique 4 (2/42 4.8%, p = 0.001). Half the failures occurred by six weeks, and the Kaplan-Meier survivorship at 24 months was 94.4% (95% confidence interval (CI) 79.6 to 98.6) for Technique 4 and 69.9% (95% CI 59.4 to 78.3) for the other techniques when combined. In multivariable survival analysis, Technique 4 had better survival than other techniques (Hazard Ratio 0.162, 95% CI 0.039 to 0.068, p = 0.013). Among 155 patients with a minimum of six months post-operative insurance coverage, re-operation occurred in 9.7% (15 patients). However, in multivariable logistic regression, Technique 4 did not reach a statistically significant lower risk for re-operation (odds ratio 0.254, 95% CI 0.05 to 1.3, p = 0.11). In this retrospective series, anatomical CC ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure. Anatomical coracoclavicular ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure. ©2016 The British Editorial

A retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database, a national representative database in Japan. The aim of this study was to examine seasonal variations in the risk of reoperation for surgical site infection (SSI) following spinal fusion surgery. Although higher rates of infection in the summer than in other seasons were thought to be caused by increasing inexperience of new staff, high temperature, and high humidity, no studies have examined seasonal variations in the risk of SSI following spinal fusion surgery in the country where medical staff rotation timing is not in summer season. In Japan, medical staff rotation starts in April. We retrospectively extracted the data of patients who were admitted between July 2010 and March 2013 from the DPC database. Patients were included if they were aged 20 years or older and underwent elective spinal fusion surgery. The primary outcome was reoperation for SSI during hospitalization. We performed multivariate analysis to clarify the risk factors of primary outcome with adjustment for patient background characteristics. We identified 47,252 eligible patients (23,659 male, 23,593 female). The mean age of the patients was 65.4 years (range, 20-101 yrs). Overall, reoperation for SSI occurred in 0.93% of the patients during hospitalization. The risk of reoperation for SSI was significantly higher in April (vs. February; odds ratio, 1.93; 95% confidence interval, 1.09-3.43, P = 0.03) as well as other known risk factors. In subgroup analysis with stratification for type of hospital, month of surgery was identified as an independent risk factor of reoperation for SSI among cases in an academic hospital, although there was no seasonal variation among those in a nonacademic hospital. This study showed that month of surgery is a risk factor of reoperation for SSI following elective spinal fusion surgery, nevertheless, in the country where medical staff rotation timing is not in

Informed decision-making about optimal surgical repair of apical prolapse with vaginal native tissue (NT) versus transvaginal mesh (TVM) requires understanding the balance between the potential "harm" of mesh-related complications and the potential "benefit" of reducing prolapse recurrence. Synthesis of data from observational studies is required and the current literature shows that the average follow-up for NT repair is significantly longer than for TVM repair. We examined this harm/benefit balance. We hypothesized that using different methods of analysis to incorporate follow-up time would affect the balance of outcomes. We used a Markov state transition model to estimate the cumulative 24-month probabilities of reoperation for mesh exposure/erosion or for recurrent prolapse after either NT or TVM repair. We used four different analytic approaches to estimate probability distributions ranging from simple pooled proportions to a random effects meta-analysis using study-specific events per patient-time. As variability in follow-up time was accounted for better, the balance of outcomes became more uncertain. For TVM repair, the incremental ratio of number of operations for mesh exposure/erosion per single reoperation for recurrent prolapse prevented increased progressively from 1.4 to over 100 with more rigorous analysis methods. The most rigorous analysis showed a 70% probability that TVM would result in more operations for recurrent prolapse repair than NT. Based on the best available evidence, there is considerable uncertainty about the harm/benefit trade-off between NT and TVM for apical prolapse repair. Future studies should incorporate time-to-event analyses, with greater standardization of reporting, in order to better inform decision-making.

OBJECTIVE The aim of this paper was to use a prospective, longitudinal, multicenter outcome registry of patients undergoing surgery for lumbar degenerative disease in order to assess the incidence and factors associated with 30-day reoperation and 90-day readmission. METHODS Prospectively collected data from 9853 patients from the Quality and Outcomes Database (QOD; formerly known as the N 2 QOD [National Neurosurgery Quality and Outcomes Database]) lumbar spine registry were retrospectively analyzed. Multivariate binomial regression analysis was performed to identify factors associated with 30-day reoperation and 90-day readmission after surgery for lumbar degenerative disease. A subgroup analysis of Medicare patients stratified by age (readmission rate was 6.3%. Multivariate analysis demonstrated that higher ASA class (OR 1.46 per class, 95% CI 1.25-1.70) and history of depression (OR 1.27, 95% CI 1.04-1.54) were factors associated with 90-day readmission. Medicare beneficiaries had a higher rate of 90-day readmissions compared with those who had private insurance (OR 1.43, 95% CI 1.17-1.76). Medicare patients readmission included higher ASA class and a history of depression. The 90-day readmission rates were higher for Medicare beneficiaries than for those who had private insurance. Medicare patients < 65 years of age were more likely to undergo reoperation within 30 days and to be readmitted within 90 days after their index surgery.

2015-10-27

Due to the variations in anatomic location, the identification of parathyroid glands may be challenging. Although there have been advances in preoperative imaging modalities, there is still a need for an accurate intraoperative guidance. Indocyanine green (ICG) is a new agent that has been used for intraoperative fluorescence imaging in a number of general surgical procedures. Its utility for parathyroid localization in humans has not been reported in the literature. We report 3 patients who underwent reoperative neck surgery for primary hyperparathyroidism. Using a video-assisted technique with intraoperative ICG fluorescence imaging, the parathyroid glands were recognized and removed successfully in all cases. Surrounding soft tissue structures remained nonfluorescent, and could be distinguished from the parathyroid glands. This report suggests a potential utility of ICG imaging in intraoperative localization of parathyroid glands in reoperative neck surgery. Future work is necessary to assess its benefit for first-time parathyroid surgery. © The Author(s) 2015.

The optimal myocardial preservation strategy at re-operation for aortic valve replacement (AVR) after prior coronary artery bypass grafting (CABG) in the presence of a patent internal thoracic artery (ITA) remains undefined. Patients undergoing AVR after prior CABG at our institution between 1 January 1996 and 31 December 2007 were identified; operative notes and outcomes were reviewed. Of 628 patients with prior CABG undergoing AVR with or without concomitant procedures, 427 patients had a patent ITA. In 390, management of the ITA was detailed in the operative note, including 251 in whom it was clamped and 139 in whom it was left uncontrolled. Groups were demographically similar, although re-operative CABG was more frequent in the clamped group (42% vs 23%, poptimal perfusion temperature when the ITA was left uncontrolled. Efforts to control the patent ITA at re-operation for AVR after prior CABG increase risk of injury and may actually increase operative mortality rate compared with leaving this critical graft open and perfusing the heart.

Full Text Available Constructing reservoirs can make more efficient use of water resources for human society. However, the negative impacts of these projects on the environment are often ignored. Optimal reoperation of reservoirs, which considers not only in socio-economic values but also environmental benefits, is increasingly important. A model of optimal reoperation of multi-reservoirs for integrated watershed management with multiple benefits was proposed to alleviate the conflict between water use and environmental deterioration. The social, economic, water quality and ecological benefits were respectively taken into account as the scheduling objectives and quantified according to economic models. River minimum ecological flows and reservoir water levels based on flood control were taken as key constraint conditions. Feasible search discrete differential dynamic programming (FS-DDDP was used to run the model. The proposed model was used in the upstream of the Nanpan River, to quantitatively evaluate the difference between optimal reoperation and routine operation. The results indicated that the reoperation could significantly increase the water quality benefit and have a minor effect on the benefits of power generation and irrigation under different hydrological years. The model can be readily adapted to other multi-reservoir systems for water resources management.

Patients want information to search for destination of care for breast-conserving surgery (BCS). To inform patients wanting a lumpectomy, we aimed to develop a pilot project that communicated composite quality measure (QM) results using a '4-star' rating system. Two patient-centered QMs were included in the model-reoperation rate (ROR) and cosmetic outcome (COSM). A prospective database was reviewed for stage 0-3 patients undergoing initial lumpectomy by three surgeons from 2010 to 2015. Self-reported COSM was assessed by survey. Multivariate analyses were used to test for interactions between surgeon and other variables known to influence RORs and COSMs. Models of surgeon profiling were developed that summed the ROR and COSM performance scores, then reported results using a Centers for Medicare and Medicaid Services (CMS) star-type system. Functionality for a patient to 'weight' the importance of the ratio of ROR:COSM before profiling was introduced. The unadjusted ROR for stage 1-3 patients for three surgeons was 9.5, 13.0, and 16.3%, respectively (p = 0.179) [overall rate 10.4% (38/366)]. After risk adjustment, differences between surgeons were observed for RORs, but not COSMs. Overall, patients reported excellent, good, fair, and poor COSMs of 55, 30, 11 and 4%, respectively. Composite star scores reflected differences in performance by surgeon, which could increase, or even disappear, dependent on the patient's weighting of the ROR:COSM ratio. Composite measures of performance can be developed that allow patients to input their weighted preferences and values into surgeon profiling before they consider a destination of care for BCS.

Parathyroid carcinoma is a rare clinical entity, which represents one of the main reasons, why surgery should be performed in specialized centres. Preoperatively, it is very difficult to distinguish between benign and malignant hyperparathyroidism. During the years 1996-2016, we performed 2,220 operations in 2,075 patients with a diagnosis of primary hyperparathyroidism. Among these 2,220 operations, there were 16 operations for parathyroid carcinoma. These 16 operations, including reoperations, were performed in four patients. Two patients had no reoperation, but another 2 patients required 14 reoperations in total. Parathyroid carcinoma was described in 0.2% of all patients with a diagnosis of primary hyperparathyroidism. The number of operations was 0.73% of all operations of primary hyperparathyroidism in years 1996-2016. Prognosis of parathyroid carcinoma is quite favourable, patients evidence a long-term survival rate after the primary operation. However, every reoperation increases the number of possible complications, including recurrent laryngeal nerve injury. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Sentinel lymph node (SLN) biopsy is the standard of care for axillary staging in breast cancer, but many clinical scenarios questioning the validity of SLN biopsy remain. Here we describe our experience with reoperative-SLN (re-SLN) biopsy after previous mastectomy. Review of the SLN database from September 1996 to December 2007 yielded 20 procedures done in the setting of previous mastectomy. SLN biopsy was performed using radioisotope with or without blue dye injection superior to the mastectomy incision, in the skin flap in all patients. In 17 of 20 patients (85%), re-SLN biopsy was performed for local or regional recurrence after mastectomy. Re-SLN biopsy was successful in 13 of 20 patients (65%) after previous mastectomy. Of the 13 patients, 2 had positive re-SLN, and completion axillary dissection was performed, with 1 having additional positive nodes. In the 11 patients with negative re-SLN, 2 patients underwent completion axillary dissection demonstrating additional negative nodes. One patient with a negative re-SLN experienced chest wall recurrence combined with axillary recurrence 11 months after re-SLN biopsy. All others remained free of local or axillary recurrence. Re-SLN biopsy was unsuccessful in 7 of 20 patients (35%). In three of seven patients, axillary dissection was performed, yielding positive nodes in two of the three. The remaining four of seven patients all had previous modified radical mastectomy, so underwent no additional axillary surgery. In this small series, re-SLN was successful after previous mastectomy, and this procedure may play some role when axillary staging is warranted after mastectomy.

PURPOSE: To establish a quality indicator that could be used in optimizing treatment for rhegmatogenous retinal detachment (RRD). METHODS: The Danish National Patient Registry was used to identify surgery conducted in Denmark for RRD in the period 01 January 2001-31 December 2009. Cases were...... identified by diagnosis and surgical codes. RESULTS: A total of 6522 cases were operated for a primary RRD in the study period, and 22% (1434 patients) were reoperated for a redetachment. A Cox regression analysis showed that the risk of redetachment was equal to or less than detachment on the fellow eye 1...... year after primary surgery with techniques not using silicone oil. The same was true 1.5 years after surgery for techniques using silicone oil. Based on this, we established a quality indicator defining failure as the need for operation for redetachment within 1 year from initial surgery when using...

All patients with primary hyperparathyroidism should undergo localization studies before reoperation, but it is not known which method is most accurate. The purpose of this prospective study was to compare the performance of planar scintigraphy with (123)I/(99m)Tc-sestamibi, (99m)Tc-sestamibi SPECT (SPECT/CT), (11)C-methionine PET/CT, and selective venous sampling (SVS) in persistent primary hyperparathyroidism. Twenty-one patients referred for reoperation of persistent hyperparathyroidism were included and investigated with (123)I/(99m)Tc-sestamibi, SPECT/CT (n = 19), (11)C-methionine PET/CT, and SVS (n = 18) before reoperation. All patients had been operated on 1-2 times previously because of hyperparathyroidism. The results of the localization studies were compared with operative findings, histology, and biochemical cure. Eighteen (86%) of 21 patients were biochemically cured. Nineteen parathyroid glands (9 adenomas, 1 atypical adenoma, and 9 hyperplastic glands) were removed from 17 patients, and 1 patient who was biochemically cured had an unclear histology result. The accuracy for localizing a pathologic parathyroid gland to the correct side of the neck was 59% (95% confidence interval [CI], 36%-79%) for (123)I/(99m)Tc-sestamibi, 19% (95% CI, 5%-42%) for SPECT/CT, 65% (95% CI, 43%-84%) for (11)C-methionine PET/CT, and 40% (95% CI, 19%-65%) for SVS (P hyperparathyroidism and is recommended as first-line imaging before reoperation. (11)C-methionine PET/CT provides valuable additional information if (123)I/(99m)Tc-sestamibi scan results remain negative. (99m)Tc-sestamibi SPECT/CT and SVS provide no additional information, compared with the combined results of (123)I/(99m)Tc-sestamibi and (11)C-methionine PET/CT imaging.

Preoperative aspirin has been studied in patients undergoing isolated coronary artery bypass graft surgery. However, there is a paucity of clinical data available evaluating perioperative aspirin in other cardiac surgical procedures. This study was designed to investigate the effects of aspirin on bleeding and transfusion in patients undergoing non-emergent, isolated, heart valve repair or replacement. Retrospective, cohort study. Academic medical center. A total of 694 consecutive patients having non-emergent, isolated, valve repair or replacement surgery at an academic medical center were identified. Of the 488 patients who met inclusion criteria, 2 groups were defined based on their preoperative use of aspirin: those taking (n = 282), and those not taking (n = 206) aspirin within 5 days of surgery. Binary logistic regression was used to examine relationships among demographic and clinical variables. No significant difference was found between the aspirin and non-aspirin groups with respect to the percentage receiving red blood cell (RBC) transfusion, mean RBC units transfused in those who required transfusion, massive transfusion of RBC, or amounts of fresh frozen plasma, cryoprecipitate, or platelets. Aspirin was not associated with an increase in the rate of re-exploration for bleeding (5.3% v 6.3%, p = 0.478). Major adverse cardiocerebral events (MACE), 30-day mortality, and 30-day readmission rates were not statistically different between the aspirin-and non-aspirin-treated groups. Preoperative aspirin therapy in elective, isolated, valve surgery did not result in an increase in transfusion or reoperation for bleeding and was not associated with reduced readmission rate, MACE, or 30-day mortality.

statistically higher than that of the $48,822.76 after PLF (p=.042). The CER of interbody fusion to PLF after the first operation was -$46,699.40 per QALY; however, of the 27 patients requiring reoperation, the incident (reoperation) rate ratio was 7.89 times higher after PLF (2.91, 26.67). The CER after the first reoperation was -$24,429.04 per QALY (relative to PLF). Two patients in the PLF cohort required a second reoperation, whereas none required a second reoperation in the PLIF/TLIF cohort. Taken collectively, the total CER for the interbody fusion is $9,883.97 per QALY. The reoperation rate was statistically higher for PLF, whereas the negative CER for the initial operation and first reoperation favors PLF. However, when second reoperations were included, the CER for the interbody fusion became $9,883.97 per QALY, suggesting moderate long-term cost savings and better functional outcomes with the interbody fusion.

Preoperative localizing studies are essential for patients with persistent or recurrent hyperparathyroidism requiring reoperation, because of loss of normal tissue planes and because the hyperfunctioning parathyroid tissue that remains is more likely to be situated in an ectopic position. The value of noninvasive and invasive localizing techniques was evaluated in 59 consecutive patients undergoing reoperation for persistent (40 patients) or recurrent (19 patients) hyperparathyroidism. Magnetic resonance imaging was performed in 17 patients; 11 results (65%) were positive, 3 (18%) were negative, and 3 (18%) were false-positive. Ultrasonography was performed in 52 patients; 29 (56%) were positive, 16 (31%) were negative, and 7 (13%) were false-positive. Computed tomography was performed on 41 patients; 19 (46%) were positive, 16 (39%) were negative, and 6 (15%) were false-positive. Thallium chloride 201-technetium 99m pertechnetate scans were used in 39 patients; 19 (49%) were positive, 11 (28%) were negative, and 9 (13%) were false-positive. One or more of these noninvasive tests was positive in 78% of the cases. Highly selective venous catheterization with measurement of immunoreactive parathyroid hormone concentration localized the abnormal parathyroid gland in 20 of 28 patients (71%) overall and in 8 of the 14 patients (57%) whose tumors were not identified by the noninvasive techniques. Since false-positive results were common, a combination of localizing studies was helpful in identifying the abnormal gland. Fifty-three of the 59 patients (90%) were successfully treated at the initial reoperation and three were successfully treated at a second reoperation. Advances in parathyroid localization have contributed to the improved surgical results in patients with persistent or recurrent hyperparathyroidism

Some patients undergoing a 2-stage revision for a periprosthetic joint infection require a repeat spacer in the interim (removal of existing spacer with insertion of a new spacer or spacer exchange) due to persistent infection. The objectives of this study are to (1) determine the factors associated with patients who receive a repeat spacer and (2) compare the infection-free survival (overall and stratified by joint type) of reimplantation in patients who did or did not receive a repeat spacer. From 2001 to 2014, 347 hip or knee 2-stage revisions that finally underwent reimplantation and had a minimum 2-year follow-up were identified. An interim spacer exchange was performed in 59 (17%) patients (exchange cohort). Patient-related and organism-related factors were compared between the exchange and non-exchange cohorts. Kaplan-Meier survival curves were performed to assess the success (absence of signs of infection, reoperation for infection, periprosthetic joint infection-related mortality) of both cohorts. Patients in the exchange group had higher comorbidity score (P = .020), prolonged time to reimplantation (P exchange cohort, and 78% (knee 77%, hip 78%) in the non-exchange cohort (P = .020). Patients requiring an interim spacer exchange were found to have more comorbidities, prolonged treatment period, and were more likely to be infected with a resistant organism. About one-third of such patients became reinfected within 5 years compared to only one-fifth of the patients without an interim spacer exchange. Copyright © 2018 Elsevier Inc. All rights reserved.

OBJECTIVE Successful transsphenoidal surgery for adrenocorticotropin hormone (ACTH)-producing pituitary tumors is associated with subnormal postoperative serum cortisol levels, which may guide decisions regarding immediate reoperation. However, little is known about the detailed temporal course of changes in serum cortisol in the immediate postoperative period, and the relationship of postoperative cortisol dynamics to remission and late recurrence. METHODS A single-center retrospective cohort analysis was performed for all patients undergoing pituitary surgery from 2007 through 2015. Standardized diagnostic and treatment algorithms were applied to all patients with potential Cushing's disease (CD), including microsurgical transsphenoidal adenomectomy (TSA) by a single surgeon. All patients had serum cortisol levels drawn at 6-hour intervals for 72 hours after surgery, and were offered reoperation within 3 days for normal or supranormal postoperative cortisol levels. Primary outcomes were 6-month remission and late recurrence; secondary outcomes were persistent postoperative hypocortisolism and surgical morbidity. Discriminatory levels of postoperative serum cortisol for predicting remission were calculated at various intervals after surgery using receiver operating characteristic (ROC) curves. RESULTS Among 89 patients diagnosed with CD, 81 underwent initial TSA for a potentially curable lesion; 23 patients (25.8%) underwent an immediate second TSA. For the entire cohort, 6-month remission was achieved in 77.8% and late recurrences occurred in 9.5%, at a mean of 43.5 months. Compared with patients with a single surgery, those with an immediate second TSA had similar rates of remission (78.3% vs 77.6%) and late recurrence (5.6% vs 11.1%). The rate of hypocortisolism for patients with 2 surgeries (12/23, 52.2%) was significantly greater than that for patients with single surgeries (13/58, 22.4%; p surgery protocol.

Although a high incidence of strut fracture of the Björk-Shiley convexo-concave (C-C) valve prosthesis has been reported, it is still controversial whether the prosthesis functioning normally should be replaced electively. To clarify our policy for this issue, we reviewed 28 patients who had undergone mitral valve replacement with a C-C valve prosthesis, and evaluated long-term results according to STS guidelines. The incidence of valve-related complications expressed as % patient-year were; structural deterioration 0.30, nonstructural dysfunction 0.30, thromboembolism 1.20. There were no thrombosed valves, anticoagulant-related hemorrhage or prosthetic valve endocarditis. The actuarial free rate after valve replacement with the C-C at 10 years, constructed by the Kaplan-Meier method, were compared with those with St. Jude Medical (SJM) valve prosthesis. (1) Actuarial survival: 77.9 vs 87.3 (NS), (2) Reoperation-free: 91.6 vs 98.0 (p valve-related complications: 71.2 vs 77.7 (NS). The long-term results with the C-C were compatible to those with a SJM valve prosthesis. However, if a strut fracture occurs, it is very difficult to save the patient's life. The hospital mortality of re-replacement of valve prosthesis during the last 10 years, at our institute, was 2.6%, which is almost equal to the cumulative risk of strut fracture of the C-C valve after 10 years (3.0%).(ABSTRACT TRUNCATED AT 250 WORDS)

Reoperative parathyroidectomy (RPTX) for persistent or recurrent hyperparathyroidism is associated with a high rate of operative failure. The long-term effectiveness of RPTX using localization studies and intraoperative parathormone monitoring (IPM) was examined. Retrospective analysis of prospectively collected data from patients undergoing targeted RPTX with IPM for persistent or recurrent hyperparathyroidism was performed. Persistent hyperparathyroidism was defined as elevated calcium and parathormone (PTH) levels above normal range less than 6 months after parathyroidectomy. Recurrent hyperparathyroidism was defined as elevated calcium and PTH levels greater than 6 months after successful parathyroidectomy. Sensitivity and positive predictive value (PPV) for sestamibi, surgeon-performed ultrasound, intraoperative PTH dynamics, and surgical outcomes were evaluated. Of the 1,064 patients, 69 patients underwent 72 RPTXs with localizing studies and IPM. Sestamibi (n = 69) had a sensitivity of 74% and a PPV of 83%, whereas surgeon-performed ultrasound (n = 38) had a sensitivity of 55% and a PPV of 76%. IPM had a sensitivity of 100% and a PPV of 98%. An intraoperative PTH drop greater than or equal to 50% was predictive of operative success (P < .01). Overall, operative success and recurrence were 94% and 1.4%, with a mean patient follow-up of 59 ± 12.8 months. RPTX can be performed in a targeted approach using preoperative localization studies and IPM, leading to a low rate of complications and a high rate of long-term operative success.

Posterior urethral distraction injury following major pelvic trauma is a surgical challenge. Although rarely seen, cases of failure after formal urethral reconstruction are even more problematic. We adapted the concept of augmented free buccal mucosal grafts, which have been successful in anterior urethroplasty, for repairing the posterior urethra in these rare cases with the aim of reducing the likelihood of penile chordee postoperatively. During 2007-2009, four patients were candidates for the proposed procedure because they had received formal transperineal urethral reconstruction but were unable to urinate through the urethra. The urethra was approached transperineally and opened in the midline, rather than divided. Buccal mucosal grafts of an appropriate size were placed in the created urethral groove from 4- to 8 o'clock in the lithotomy view. After the procedure, the urethral catheter was kept for 3 weeks. All patients voided through the urethra after the procedure. The maximal postoperative urinary flow rates were between 12-15 ml/seconds in all cases for a follow-up period of 18-30 months. The recurrence rate was 50% (2/4). Recurrent strictures were minor, and they showed a web-like stricture ring near the suture line. Restricture within 6 months of surgery responded well to endoscopic internal urethrotomy plus dilatations. In conclusion, without further compromising urethral length, reoperative posterior urethroplasty with the inlay grafting technique can be considered in selective cases. Copyright © 2012.

Full Text Available Prosthetic valve re-operation has greater mortality and morbidity than primary valve replacement. By recognition of factors influencing on causes of redo operation and preoperative survival, one can select appropriate prosthesis at primary valve replacement and when operation performed at appropriate time, surgical risk can be reduced."nMethods and Materials: Two hundred patients that underwent prosthetic valve re-operation from October 1991 through November 2001 were included in this study. There were 68 men and 132 women with the mean age of 42:tl 1.8 years. Structural failure was the commonest cause of bio-prosthesis replacement (93%. Valve thrombosis was the common cause of mechanical valve replacement (32%. Age younger Than 50 (P= 0.01 and interval after the first implantation more than 10 years (P= 0.01 affected bio-prosthesis degeneration."nResults: Atrial fibrillation (P<0.01, Older age especially more than 40 (P<0.05 and mitral position (P<0.01 affected mechanical valve thrombosis. Cross clamp time (P= 0.005, Tricuspid insufficiency (P = 0.001, NYHA IV (P = 0.005 and emergent operation (P= 0.001 were independent determinants of hospital mortality."nConclusion: In conclusion, in patients with more than 10-years life expectancy and age younger than 50, mechanical valve can be selected for primary valve replacement. If operation performed before patients reach deteriorated condition, preoperative survival would be excellent.

Background The management of meniscus tears identified at the time of primary ACL reconstruction is highly variable and includes repair, meniscectomy, and non-treatment. Hypothesis/Purpose The purpose of this study is to determine the reoperation rate for meniscus tears left untreated at the time of ACL reconstruction with minimum follow-up of 6 years. We hypothesize that small, peripheral tears identified at the time of ACL reconstruction managed with “no treatment” will have successful clinical outcomes. Study Design Retrospective study of a prospective cohort; Level of Evidence, 3 Methods Patients with meniscus tears left untreated at the time of primary ACL reconstruction were identified from a multicenter study group with minimum 6-year follow-up. Patient, tear, and reoperation data were obtained for analysis. Need for reoperation was used as the primary endpoint, with analysis performed to determine patient and tear characteristics associated with reoperation. Results There were 194 patients with 208 meniscus tears (71 medial; 137 lateral) left in situ without treatment with complete follow-up for analysis. Of these, 97.8% of lateral and 94.4% of medial untreated tears required no reoperation. Sixteen tears (7.7%) left in situ without treatment underwent subsequent reoperation: 9 tears (4.3%) underwent reoperation in the setting of revision ACL reconstruction and 7 tears (3.4%) underwent reoperation for isolated meniscus pathology. Patient age was significantly lower in patients requiring reoperation, while tears measuring ≥ 10 mm more frequently required reoperation. Conclusions Lateral and medial meniscus tears left in situ at the time of ACL reconstruction did not require reoperation at minimum 6-year follow-up for 97.8% and 94.4% of tears, respectively. These findings reemphasize the low reoperation rate following non-treatment of small, peripheral lateral meniscus tears while noting less predictable results for medial meniscus tears left without

In patients with Marfan syndrome (MFS), valve reimplantation has been proposed as superior to root remodeling. In the present study, both forms of valve-preserving root repair were applied and mid-term results analyzed in MFS patients compared to a propensity score-matched cohort. Among 604 patients who underwent valve-preserving aortic root surgery between 1995 and 2011 at the authors' institution, 33 MFS patients (16 males, 17 females; mean age 31 +/- 12 years) underwent either remodeling (n=21) or reimplantation (n=12). All patients were followed up echocardiographically, and the outcome with regard to late aortic valve regurgitation (AR) grade EII and reoperation on the aortic valve was compared between MFS patients and the matched cohort (n=33). Baseline characteristics and operative data were similar between the groups. Actuarial freedom from AR > or = II at seven years was 86 +/- 8% in MFS patients and 90 +/- 10% in matched non-MFS patients (p = 0.94). Actuarial freedom from reoperation at seven years was 90 +/- 7% in MFS patients and 100% in non-MFS patients (p = 0.79). In Cox's proportional hazard's model, no independent risk factor, including MFS, was found for recurrent AR or reoperation. Within the MFS patients, remodeling and reimplantation provided an almost identical freedom from late AR > or = II and reoperation up to five years postoperatively (p = 0.55 and 0.99, respectively). The stability of valve-preserving aortic root repair was comparable between patients with or without MFS. Both forms of valve-preserving root repair can provide similar mid-term results for MFS patients, primarily according to their root geometry. However, additional long-term follow up data based on a larger number of patients are required to confirm the evidence obtained to date.

Although reoperation rates for upper lid retraction surgery for thyroid eye disease (TED) typically range between 8% and 23%, there is little literature describing the outcomes of these second operations. In this retrospective observational cohort study, all patients that underwent surgery for upper eyelid retraction over a 14-year period at a single institution were included. Cases were included if a second eyelid retraction surgery was performed during the study period. Success of surgery was defined as a marginal reflex distance (MRD1) of 2.5 to 4.5 mm in each eye and less than 1 mm difference in MRD1 between the eyes. Overcorrection and undercorrection were defined as above and below these bounds, respectively. 72 eyes in 49 patients were included in the study. The mean age was 56.6 (±11.5) years. By definition, all patients had at least 1 lid lengthening surgery for upper eyelid retraction, and at least 1 subsequent surgery. For this second surgery, 61 eyes (85%) underwent retraction surgery and 11 eyes (15%) underwent ptosis surgery. After this second operation, 31% were undercorrected and 33% were overcorrected. A third surgery was performed in 19 eyes (25%), 12 had surgery for residual retraction and 7 for ptosis. After the third operation 10% of eyes were under corrected and 11% were over corrected. Four patients underwent a fourth surgery: one for retraction and three for ptosis. Success was noted in 35% after the second surgery and 44% after the third. Surgical success in eyelid retraction surgery increases from a second to a third consecutive surgery, and residual asymmetry was roughly equally distributed between over- and undercorrection.

The overall incidence of re-operation and prosthetic valve endocarditis was low in the present series as mechanical prostheses were used predominantly. The prosthetic dysfunctions were less frequent following the primary implantation with Bjork Shiley prostheses, but high operative risk was associated with the clotted Bjork Shiley prostheses. We also had unusual experience of strut fracture and sticking of Bjork Shiley discs in the closed position in both aortic and mitral positions. The early deaths were nil since the use of cardioplegic protection. Intra-operative bleeding due to adhesions can be minimised by using synthetic or heterologous pericardium during the primary operation.

Post-traumatic arthritis (PTA) is characterized by the deterioration of articular cartilage temporally associated with an articular injury. With a paucity of literature comparing joint preservation techniques, we performed a systematic review of the literature intending to describe and summarize the results of ankle distraction arthroplasty as it compares with studies on tibio-talar microfracture, allograft, and autograft for ankle joint preservation in the post-traumatic population under 50 years of age. Research databases were searched and abstracts screened for relevance on our topic of interest. Abstracts meeting screening criteria with high interobserver reliability underwent full-manuscript review and coding for pertinent citation, study level, treatment, and outcome variables. Outcome variables for patient-reported pain scales, validated outcome measurement tools, radiographic progression, reoperation/re-treatment rates, and complication rates were recorded. Out of 105 unique citations, 10 publications were included. The distraction arthroplasty studies had 36 out of 181 patients requiring reoperation for complications (19.9%), while other joint-preserving procedures studies had 40 out of 177 patients requiring reoperations for complications (22.6%). Clinical outcome scores at mean follow-up time ranging from 2 to 10 years between studies were similar. Reported results for a variety of cartilage preservation procedures, including distraction arthroplasty, are satisfactory and reoperation rates for complication are similar. Limitations in available data and underlying study quality affect synthesis of the results therein. While distraction arthroplasty is an option for cartilage preservation in patients with PTA of the ankle, the technique is highly specialized which may affect the external validity. III.

The Florida sleeve (FS) procedure was developed as a simplified approach for repair of functional type I aortic insufficiency secondary to aortic root aneurysm. We evaluated postoperative aortic valve function, long-term survival, and freedom from reoperation in Marfan syndrome patients who underwent the FS procedure at our center. All Marfan syndrome patients undergoing FS procedure from May 2002 to December 2014 were included. Echocardiography assessment included left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), ejection fraction, and degree of aortic insufficiency (none = 0, minimal = 1, mild = 2, moderate = 3, severe = 4). Social Security Death Index and primary care physicians' report were used for long-term follow-up. Thirty-seven Marfan syndrome patients, 21 (56.8%) men and 16 (43%) women with mean age of 35.08 ± 13.45 years underwent FL repair at our center. There was no in-hospital or 30-day death or stroke. Two patients required reoperation due to bleeding. Patients' survival rate was 94% at 1 to 8 years. Freedom from reoperation was 100% at 8 years. Twenty-five patients had postoperative follow-up echocardiography at 1 week. Aortic insufficiency grade significantly decreased after the procedure (preoperative mean ± SD: 1.76 ± 1.2 versus 1-week postoperative mean ± SD: 0.48 ± 0.71, p Marfan syndrome patients with immediate improvement in aortic valve function. Long-term survival and freedom from reoperation rates are encouraging. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

From 1985 to 1996, 18 patients with Marfan's syndrome underwent the Bentall procedure at Mount Sinai Hospital. They are compared with 38 patients aged Marfan's syndrome who also underwent composite valve-graft replacement of the ascending aorta. The mean age of the non-Marfan group was 33 while that of the Marfan group was 29. Nearly three-quarters of each group were male. Aortic dissection was present in 33% of the Marfan group but only in 18% of the other group. Seventy-eight percent of the Marfan patients and 89% of the non-Marfan patients had aortic regurgitation. Twenty-one percent of the patients in the control group nevertheless had gross aortic pathology suggestive of Marfan's syndrome and may have had variants of the syndrome; 26% of the non-Marfan group had a bicuspid aortic valve. A modification of the Bentall procedure with implantation of coronary artery buttons was performed in the majority of the patients in both groups. Three patients, all in the group with Marfan's syndrome, required a concomitant mitral valve procedure. There was one death in each group. Two non-Marfan patients required reoperation; neither had dissection. Four patients with Marfan's syndrome underwent reoperation for distal disease in the aorta; they comprised one third of the Marfan patients who had aortic dissection. Three late complications occurred in the group with Marfan's syndrome: progressive cardiomyopathy; myocardial infarction; and late tamponade. There were also two late sudden deaths in the group with Marfan's syndrome, which may have been the consequence of aortic rupture. No difference in immediate operative mortality following the Bentall procedure was noted between patients with and without Marfan's syndrome, but young patients without Marfan's syndrome seem to have better event-free and long-term survival. In patients with Marfan's syndrome, the presence of acute dissection makes reoperation more likely, and sudden death from rupture still occurs despite careful

The use of the frozen elephant trunk (FET) technique for repair of type A aortic dissection (TAAD) in Marfan syndrome (MFS) is controversial. We seek to evaluate the efficacy of FET and total arch replacement (TAR) for TAAD in patients with MFS. The early and long-term outcomes were analyzed for 106 patients with MFS (mean age, 34.5 ± 9.7 years) undergoing FET + TAR for TAAD. Operative mortality was 6.6% (7 of 106). Spinal cord injury and stroke occurred in 1 patient each (0.9%), and reexploration for bleeding occurred in 6 patients (5.7%). Extra-anatomic bypass was the sole risk factor for operative mortality and morbidity (odds ratio [OR], 7.120; 95% confidence interval [CI], 1.018-49.790; P = .048). Follow-up was complete in 97.0% (96 of 99), averaging 6.3 ± 2.8 years. Late death occurred in 17 patients. Patients with acute TAAD were less prone to late death than those with chronic TAAD (OR, 0.112; 95% CI, 0.021-0.587; P = .048). Twelve patients required late reoperation, including thoracoabdominal aortic repair in 8, thoracic endovascular aortic repair for distal new entry in 3, and coronary anastomotic repair in 1. At 5 years, survival was 86.6% (95% CI, 77.9%-92.0%) and freedom from reoperation was 88.8% (95% CI, 80.1%-93.4%), and at 8 years, survival was 74.1% (95% CI, 61.9%-83.0%) and freedom from reoperation was 84.2% (95% CI, 72.4%-91.2%). In competing risks analysis, mortality was 4% at 5 years, 18% at 8 years, and 25% at 10 years; the respective rates of reoperation were 10%, 15%, and 15%; and the respective rates of survival without reoperation were 86%, 67%, and 60%. Survival was significantly higher in patients who underwent root procedures during FET + TAR (P = .047). Risk factors for reoperation were days from diagnosis to surgery (OR, 1.160; 95% CI, 1.043-1.289; P = .006) and Bentall procedure (OR, 12.012; 95% CI, 1.041-138.606; P = .046). The frozen elephant trunk and total arch replacement procedure can be safely performed

To evaluate the risk factors affecting unplanned reoperation (URO) after laparoscopic gastrectomy (LAG) for gastric cancer (GC) and establish a model to predict URO preoperatively. Between May 2007 and December 2014, we prospectively collected and retrospectively analyzed the data of 2608 GC patients who underwent LAG. Among them, 2580 patients not requiring an URO were defined as the Non-URO group, and 28 patients requiring an URO were defined as the URO group. Univariate, multivariate, and bootstrap analyses were performed to determine the independent predictors for URO, and a nomogram was constructed to preoperatively predict the rate of URO after LAG. Of the 2608 patients, the URO rate was 1.1% (28/2608) within the 30-day hospitalization. The mean URO time interval to first operation was 5.6 ± 5.5 (0.10-18.5) days. The main causes requiring URO were intraabdominal bleeding (57.1%), anastomotic bleeding (17.9%), anastomotic leakage (7.1%), and intraabdominal infection (7.1%). Compared to the Non-URO group, the URO group had a significantly longer hospital stay (p 70 years (odds ratio (OR) = 2.232, 95% confidence interval (CI) = 1.023-4.491, p = 0.028), male gender (OR = 32.983, 95% CI 1.405-25.343 × 10 6 , p = 0.027), and body mass index (BMI) > 25 kg/m 2 (OR = 2.550, 95% CI 1.017-5.398, p = 0.012) were independent risk factors for URO. A multivariable nomogram model for predicting URO exhibited a strong optimism-adjusted discrimination (concordance index, 0.687). No significant correlation was noted between the URO rate and operative period by Spearman analysis (r = 0.012, p = 0.548). Age > 70 years, Male, and BMI > 25 kg/m 2 were independent risk factors for URO. Based on the three risk factors, we developed a simple and practical nomogram to predict URO preoperatively, which might aid surgeons in reducing the URO rate when planning to perform LAG for GC.

Postoperative intra-abdominal massive bleeding is a rare and life-threatening complication associated with pancreaticoduodenectomy. Completion pancreatectomy (CP) was usually performed during reexploration for the complication. The management could decrease the complications, such as the pancreatic leakage or intraluminal infection after reexploration, but could increase mortality during the perioperative period. It also could result in loss of pancreatic function forever. This study evaluated an alternative surgical management for intra-abdominal massive hemorrhage to prevent pancreas function, simplify the surgical processes, and decrease the mortality of relaparotomy. Outcome after pancreaticojejunal bridge-anastomosis (PJBA) performed between January 2006 and June 2009 was compared with that after CP performed between February 1984 and December 2005. Between February 1984 and June 2009, 963 patients underwent the Whipple procedure (PD) or pylorus-preserving pancreaticoduodectomy (PPPD). Pancreatic leakage occurred in 103 patients (10.7%); 22 cases (21.4%) developed into intra-abdominal massive bleeding. Nonsurgical procedures of transarterial embolization (TAE) were performed in ten (45.45%) patients, of whom one died (10%). Twelve (54.55%) underwent reoperation. Five had CP with one death (20%). Pancreatic remnant was preserved by pancreaticojejunal bridge-anastomosis (PJBA) in seven patients with no deaths. The reexploration time was 340 +/- 48.2 min vs. 247.9 +/- 40.8 min (P endocrine insufficiency ("brittle" diabetes) and diarrhea (exocrine insufficiency). There were no evidences of exocrine and endocrine insufficiency in patients with PJBA. Pancreaticojejunal bridge-anastomosis is an easy, simple, and safe procedure for intra-abdominal massive hemorrhage associated with pancreaticoduodenectomy. It could decrease the mortality of reoperation and preserve the pancreatic function.

Left ventricular outflow tract obstruction (LVOTO) is the second most frequent reason for reoperation after atrioventricular canal (AVC) defect repair. Limited data are available on the mechanisms of LVOTO, their treatment, and outcomes. Between 1998 and 2010, 56 consecutive children with AVC underwent 68 LVOTO procedures. The AVC was partial in 4, transitional in 9, and complete in 43. The LVOTO procedure was required in 21 patients at the primary AVC repair, and the initial LVOTO procedure in 35 patients was a late reoperation after AVC repair. During a mean follow-up of 50±41 months, 5 patients (24%) with LVOTO repair at AVC repair required a reoperation for LVOTO, and 7 patients (20%) whose initial LVOTO repair was a reoperation required a second reoperation for LVOTO repair. Overall freedom from LVOTO reoperation was 98.5% at 1 year, 92.5% at 3 years, 81% at 5 years, 72.2% at 7 years, and 52.5% at 10 and 12 years. The freedom from reoperation was neither significantly different between partial, transitional, and complete AVC (p=0.78) nor between timing of the LVOT procedure (p=0.49). Modified single-patch AVC repair was associated with a higher LVOTO reoperation rate (p=0.04). Neither the mechanisms leading to LVOTO nor the surgical techniques used were independent predictors of reoperation. LVOTO in AVC is a complex and multifactorial disease. Aggressive surgical repair has improved late outcomes; however, risk factors for reoperation and the ideal approach for repair remain to be defined. Copyright © 2012 The Society of Thoracic Surgeons.

Pedicle screws are routinely used in contemporary spinal surgery. Screw misplacement may be asymptomatic but is also correlated with potential adverse events. Computer-assisted surgery (CAS) has been associated with improved screw placement accuracy rates. However, this technology has substantial acquisition and maintenance costs. Despite its increasing usage, no rigorous full economic evaluation comparing this technology to current standard of care has been reported. Medical costs are exploding in an unsustainable way. Health economic theory requires that medical equipment costs be compared with expected benefits. To answer this question for computer-assisted spinal surgery, we present an economic evaluation looking specifically at symptomatic misplaced screws leading to reoperation secondary to neurologic deficits or biomechanical concerns. The study design was an observational case-control study from prospectively collected data of consecutive patients treated with the aid of CAS (treatment group) compared with a matched historical cohort of patients treated with conventional fluoroscopy (control group). The patient sample consisted of consecutive patients treated surgically at a quaternary academic center. The primary effectiveness measure studied was the number of reoperations for misplaced screws within 1 year of the index surgery. Secondary outcome measures included were total adverse event rate and postoperative computed tomography usage for pedicle screw examination. A patient-level data cost-effectiveness analysis from the hospital perspective was conducted to determine the value of a navigation system coupled with intraoperative 3-D imaging (O-arm Imaging and the StealthStation S7 Navigation Systems, Medtronic, Louisville, CO, USA) in adult spinal surgery. The capital costs for both alternatives were reported as equivalent annual costs based on the annuitization of capital expenditures method using a 3% discount rate and a 7-year amortization period

estimations using the restricted maximum likelihood method. There was no difference in the proportion of Asian patients versus Western patients undergoing reoperation for any cause calculated as 100 component observed years (1.022 of 3152 Asian patients; 95% CI, 0.810-1.235 versus 1.300 of 5455 Western patients; 95% CI, 1.067-1.534; odds ratio, 0.7839; 95% CI, 0.5323-1.1545; p = 0.178). The mean reoperation rate attributable to bearing dislocation per 100 observed years was higher in Asian than in Western patients (0.525; 95% CI, 0.407-0.643 versus 0.141; 95% CI, 0.116-0.166; odds ratio, 3.7378; 95% CI, 1.694-8.248; p = 0.001) Conversely, the mean reoperation rate attributable to lateral knee OA per 100 observed years was lower in Asian than in Western patients (0.093; 95% CI, 0.070-0.115 versus 0.298; 95% CI, 0.217-0.379; odds ratio, 0.3114; 95% CI, 0.0986-0.9840; p bearing dislocation was more likely to occur in Asian than in Western patients, whereas reoperation for lateral knee OA progression was more likely to occur in Western than in Asian patients after Oxford Phase III UKA. Although possible explanations for these findings may be hypothesized, additional randomized, prospective comparative studies are needed. However, better survival outcomes after UKA may require consideration of ethnicity and lifestyle choices in addition to traditional surgical technique and perioperative care.

A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications. Copyright 2001 Academic Press.

To compare the recurrence rate and need for reoperation after epiretinal membrane surgery with and without removal of the internal limiting membrane. In this retrospective study, 125 patients operated for epiretinal membrane removal were evaluated, with a minimum 6-month follow-up. Removal of the epiretinal membrane (ERM) was performed in 78 patients, while 47 had removal of the epiretinal membrane associated with internal limiting membrane peeling (ERM + ILM). The mean age in the ERM group was 65.8 years old, ranging from 41 to 80 years old. In the ERM + ILM group, the mean age was 67.2 years old, ranging from 52 to 82 years old. The mean preoperative visual acuity in the ERM group was 20/80p, and in the ERM + ILM group, it was 20/80. The mean postoperative visual acuity in both groups was 20/30. The mean preoperative macular thickness in the ERM group was 467 µm ranging from 281 to 663 µm; in the ERM + ILM group, the preoperative macular thickness was 497 µm, ranging from 172 to 798 µm. After surgery, a reduction in macular thickness was observed in both groups. In the ERM group, the mean macular thickness reduction was 361 ± 101. µm, whereas in the ERM + ILM group, it was 367 ± 75.2 µm. Twenty-two patients presented with a recurrence of epiretinal membrane, of which 16 (20.5%) were from the ERM group and 6 (12.8%) were from the ERM + ILM group (p = 0.39); one patient (2%) was retreated in the ERM + ILM group, whereas 5 patients (6%) where retreated in the ERM group. We postulate that ILM peeling for the treatment of epiretinal membrane is not a relevant factor either for visual recovery or macular thickness reduction, but it may reduce the recurrence and reoperation rate.

Full Text Available OBJETIVOS: Avaliar o resultado do tratamento cirúrgico, por via aberta ou artroscópica, dos pacientes com recidiva sintomática da lesão do manguito rotador. MÉTODOS: Foram avaliados 30 pacientes entre dezembro de 1990 e julho de 2007 submetidos a um novo procedimento cirúrgico pelo Grupo de Cirurgia de Ombro e Cotovelo do Departamento de Ortopedia e Traumatologia da Santa Casa de São Paulo - Pavilhão Fernandinho Simonsen devido à deiscência da sutura do manguito rotador. Foram incluídos pacientes com recidivas sintomáticas da lesão e com tempo de seguimento mínimo pós-operatório de 24 meses. RESULTADOS: Pelos critérios de avaliação da UCLA, 21 (70% pacientes tiveram resultados excelentes e bons; nove (30% pacientes tiveram resultados regulares e ruins. CONCLUSÃO: O tratamento cirúrgico, por via aberta e artroscópica, das recidivas da lesão do manguito rotador tende a apresentar resultados piores que o reparo primário. Neste estudo, obtivemos 70% de resultados excelentes e bons. A presença de lesões extensas na segunda operação tende a evoluir com um maior número de resultados insatisfatórios. No nosso estudo, obtivemos melhores resultados com a cirurgia realizada por via artroscópica em comparação com a via aberta.OBJECTIVES: To assess the results from open or arthroscopic surgical treatment on patients with symptomatic recurrence of rotator cuff injuries. METHODS: Between December 1990 and July 2007, 30 patients were assessed and underwent reoperation performed by the Shoulder and Elbow Surgery Group of the Department of Orthopedics and Traumatology, Fernandinho Simonsen Wing, Santa Casa de São Paulo, because of dehiscence of the rotator cuff suture. The study included patients with symptomatic recurrence of the injury and with at least 24 months of postoperative follow- up. RESULTS: According to the UCLA evaluation criteria, 21 patients (70% showed excellent or good outcomes; and nine patients (30% showed fair

Many insurance companies require patient participation in a medically supervised weight management program (WMP) before offering approval for bariatric surgery. Clinical data surrounding benefits of participation are limited. To evaluate the relationship between preoperative insurance-mandated WMP participation and postoperative outcomes in bariatric surgery patients. Regional referral center and teaching hospital. A retrospective review of patients who underwent vertical sleeve gastrectomy or Roux-en-Y gastric bypass between January 2014 and January 2016 was performed. Patients (N = 354) were divided into 2 cohorts and analyzed according to presence (n = 266) or absence (n = 88) of an insurance-mandated WMP requirement. Primary endpoints included rate of follow-up and percent of excess weight loss (%EWL) at postoperative months 1, 3, 6, and 12. All patients, regardless of the insurance-mandated WMP requirement, followed a program-directed preoperative diet. The majority of patients with an insurance-mandated WMP requirement had private insurance (63.9%). Both patient groups experienced a similar proportion of readmissions and reoperations, rate of follow-up, and %EWL at 1, 3, 6, and 12 months (P = NS). Median operative duration and hospital length of stay were also similar between groups. Linear regression analysis revealed no significant improvement in %EWL at 12 months in the yes-WMP group. These data show that patients who participate in an insurance-mandated WMP in addition to completing a program-directed preoperative diet experience no significant benefit to rate of readmission, reoperation, follow-up, or %EWL up to 12 months postoperation. Our findings suggest that undergoing bariatric surgery without completing an insurance-mandated WMP is safe and effective. Copyright © 2018 American Society for Bariatric Surgery.

Risk Balancing of Cold Ischemic Time against Night Shift Surgery Possibly Reduces Rates of Reoperation and Perioperative Graft Loss

Directory of Open Access Journals (Sweden)

Full Text Available Background. This retrospective cohort study evaluates the advantages of risk balancing between prolonged cold ischemic time (CIT and late night surgery. Methods. 1262 deceased donor kidney transplantations were analyzed. Multivariable regression was used to determine odds ratios (ORs for reoperation, graft loss, delayed graft function (DGF, and discharge on dialysis. CIT was categorized according to a forward stepwise pattern ≤1h/>1h, ≤2h/>2h, ≤3h/>3h,…, ≤nh/>nh. ORs for DGF were plotted against CIT and a nonlinear regression function with best R2 was identified. First and second derivative were then implemented into the curvature formula k(x=f′′(x/(1+f′x23/2 to determine the point of highest CIT-mediated risk acceleration. Results. Surgery between 3 AM and 6 AM is an independent risk factor for reoperation and graft loss, whereas prolonged CIT is only relevant for DGF. CIT-mediated risk for DGF follows an exponential pattern fx=A·(1+k·eI·x with a cut-off for the highest risk increment at 23.5 hours. Conclusions. The risk of surgery at 3 AM–6 AM outweighs prolonged CIT when confined within 23.5 hours as determined by a new mathematical approach to calculate turning points of nonlinear time related risks. CIT is only relevant for the endpoint of DGF but had no impact on discharge on dialysis, reoperation, or graft loss.

BACKGROUND: Rehabilitation after hip fracture may be lengthy, with bed-day consumption accounting for up to 85% of the total cost of admission to hospital. Data suggest that surgical complications requiring reoperation may lead to an excessively long in-patient stays. However, the overall impact...... of surgical complications has not been examined in detail. METHODS: All 600 consecutive patients included were admitted with primary hip fracture and received primary surgical intervention with multimodal rehabilitation. Surgical complications were audited and classified as being due to a patient fall......, infection or suboptimal surgery, stratified into either requiring reoperation or not allowing mobilisation because of instability. RESULTS: Of the 600, 116 (19.3, 95% CI 16-22%) patients underwent reoperation or immobilisation; 27.1% of bed-day consumption resulted from surgical complications. The audit...

Treatment failure with recurrent dysphagia after Heller myotomy occurs in fewer than 10 % of patients, most of whom will seek repeat surgical intervention. These reoperations are technically challenging, and as such, there exist only limited reports of reoperation with esophageal preservation. We retrospectively reviewed the records of patients who sought operative intervention from March 1998 to December 2014 for obstructed swallowing after esophagogastric myotomy. All patients underwent a systematic approach, including complete hiatal dissection, takedown of prior fundoplication, and endoscopic assessment of myotomy. Patterns of failure were categorized as: fundoplication failure, inadequate myotomy, fibrosis, and mucosal stricture. A total of 58 patients underwent 65 elective reoperations. Four patients underwent esophagectomy as their initial reoperation, while three patients ultimately required esophagectomy. The remainder underwent reoperations with the goal of esophageal preservation. Of these 58, 46 were first-time reoperations; ten were second time; and two were third-time reoperations. Forty-one had prior operations via a trans-abdominal approach, 11 via thoracic approach, and 6 via combined approaches. All reoperations at our institution were performed laparoscopically (with two conversions to open). Inadequate myotomy was identified in 53 % of patients, fundoplication failure in 26 %, extensive fibrosis in 19 %, and mucosal stricture in 2 %. Intraoperative esophagogastric perforation occurred in 19 % of patients and was repaired. Our postoperative leak rate was 5 %. Esophageal preservation was possible in 55 of the 58 operations in which it was attempted. At median follow-up of 34 months, recurrent dysphagia after reoperation was seen in 63 % of those with a significant fibrosis versus 28 % with inadequate myotomy, 25 % with failed wrap, and 100 % with mucosal stricture (p = 0.10). Laparoscopic reoperation with esophageal preservation is

Aortic aneurysm formation leading eventually to aortic rupture or dissection in early adult life is a fatal outcome of Marfan syndrome (MFS). Advances in the treatment of the syndrome have improved prognosis, but the long-term reoperation rate is still high. It remains unknown which factors influence the long-term prognosis, including the reoperation and mortality rates, in surgically treated Chinese patients with MFS. The authors studied 125 such patients to investigate factors influencing prognosis after aortic surgery. A retrospective clinical investigation. An academic medical center. One hundred twenty-five Marfan patients who had undergone aortic surgery. None. The indications for aortic surgery were aortic aneurysm and/or dissection in the 125 Marfan patients. The most commonly performed procedure was the Bentall in 92 patients. Sixteen patients underwent total arch replacement combined with stented elephant trunk implantation. Ten patients underwent the David procedure. Overall in-hospital and 30-day mortality rate was 1.6%. The survival rate was 97.5%, 91.4%, and 74.2% at 1, 5, and 10 years after surgery, respectively. The reoperation rate was 2.5%, 12.9%, and 32.9% at 1, 5, and 10 years after surgery, respectively. Multivariate analysis revealed that increased systolic blood pressure (Sys BP) was the predictor of death (p < 0.05), and body mass index and smoking were significant predictors of reoperation (p < 0.05). The present findings report the factors influencing the prognosis of Chinese patients with MFS after aortic surgical procedures. Managing these risk factors may enable health care professionals to improve the prognosis of MFS patients after aortic surgical procedures. Copyright © 2011 Elsevier Inc. All rights reserved.

Pericardial or mediastinal hemorrhage requiring reoperation occurs in 2% to 5% of patients, usually early (0 to 48 hours), after open-heart surgery. This hemorrhage may be occult, and resulting cardiac tamponade may easily be misinterpreted as ventricular dysfunction, common early postoperatively. In such cases, appropriate and timely intervention may not occur. Of 50 patients evaluated by technetium-99m red blood cell gated equilibrium radionuclide ventriculography (RNV) because of early postoperative cardiogenic shock of uncertain etiology, 17 had unique scintigraphic images suggestive of intrathoracic hemorrhage. Of these 17, 5 had a generalized halo of abnormal radioactivity surrounding small hyperdynamic right and left ventricles, 11 had localized regions of intense blood pool activity outside the cardiac chambers (two with compression of single chambers), and one demonstrated marked radionuclide activity in the right hemithorax (2000 ml of blood at reoperation). Twelve patients had exploratory reoperation for control of hemorrhage as a direct result of the scintigraphic findings, three were successfully treated with fresh frozen plasma and platelet infusions along with medical interventions to optimize cardiac performance, and two patients died in cardiogenic shock (presumed tamponade) without reoperation. In the 12 reoperated patients, all were confirmed to have active pericardial bleeding. Scintigraphic localization of abnormal blood pools within the pericardium corresponded to the sites at which active bleeding was witnessed at reoperation. The abnormal bleeding was etiologically related to the tamponade state, with marked improvement in hemodynamics after reoperation. Nine additional patients were reoperated for presumed tamponade after RNV revealed an exaggerated halo of photon deficiency surrounding the cardiac chambers

Should patients with Björk-Shiley valves undergo prophylactic replacement?

1992-08-29

About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that

Amputation revision rates following major upper-extremity amputations have not been previously reported in a large cohort of patients. We hypothesized that the revision rates following major upper-extremity amputation were higher than the existing literature would suggest, and that surgical treatment of complications and persistent symptoms would lead to improved outcomes. We performed a retrospective analysis of a consecutive series of ninety-six combat-wounded personnel who had sustained a total of 100 major upper-extremity amputations in Operation Iraqi Freedom and Operation Enduring Freedom. Prerevision and postrevision outcome measures, including prosthesis use and type, the presence of phantom and residual limb pain, pain medication use, and return to active military duty, were identified for all patients. All amputations resulted from high-energy trauma, with 87% occurring secondary to a blast injury. Forty-two residual limbs (42%) underwent a total of 103 repeat surgical interventions. As compared with patients with all other levels of amputation, those with a transradial amputation were 4.7 (95% confidence interval [CI]: 1.75 to 12.46) times more likely to have phantom limb pain and 2.8 (95% CI: 1.04 to 7.39) times more likely to require neuropathic pain medications. In the group of patients who underwent revision surgery, regular prosthesis use increased from 19% before the revision to 87% after it (p < 0.0001). In our cohort, revision amputation to address surgical complications and persistently symptomatic residual limbs improved the patient's overall acceptance of the prosthesis and led to outcomes equivalent to those following amputations that did not require revision.

Patients with diabetes are at increased risk of wound complications after open reduction and internal fixation of unstable ankle fractures. A fibular nail avoids large surgical incisions and allows anatomical reduction of the mortise. We retrospectively reviewed the results of fluoroscopy-guided reduction and percutaneous fibular nail fixation for unstable Weber type B or C fractures in 24 adult patients with type 1 or type 2 diabetes. The re-operation rate for wound dehiscence or other indications such as amputation, mortality and functional outcomes was determined. Two patients developed lateral side wound infection, one of whom underwent wound debridement. Three other patients required re-operation for removal of symptomatic hardware. No patient required a below-knee amputation. Six patients died during the study period for unrelated reasons. At a median follow-up of 12 months (7 to 38) the mean Short Form-36 Mental Component Score and Physical Component Score were 53.2 (95% confidence intervals (CI) 48.1 to 58.4) and 39.3 (95% CI 32.1 to 46.4), respectively. The mean Visual Analogue Score for pain was 3.1 (95% 1.4 to 4.9). The mean Ankle Osteoarthritis Scale total score was 32.9 (95% CI 16.0 to 49.7). Fluoroscopy-guided reduction and fibular nail fixation of unstable ankle fractures in patients with diabetes was associated with a low incidence of wound and overall complications, while providing effective surgical fixation.

Risk of reoperation and loss of a second native valve are major drawbacks of the Ross operation. Rather than discarding the failed autograft, it can be placed back into the native pulmonary position by "Ross reversal." We review our early and mid-term results with this operation. From 2006 to 2017, 39 patients underwent reoperation for autograft dysfunction. The autograft was successfully rescued in 35 patients: by Ross reversal in 30, David procedure in 4, and autograft repair in 1. Medical records were reviewed for patient characteristics (mean age was 46 ± 13 years, range 18-67 years, and 23 were male), previous operations, indications for reoperation, hospital outcomes, and echocardiographic findings for the 30 patients undergoing successful Ross reversal. Follow-up was 4.1 ± 3.5 years (range 7 months-11 years). Median interval between the original Ross procedure and Ross reversal was 12 years (range 5-19 years). Eight patients also had absolute indications for replacement of the pulmonary allograft. There was no operative mortality. One patient required reoperation for bleeding. Another had an abdominal aorta injury from use of an endoballoon clamp. There was no other major postoperative morbidity, and median postoperative hospital stay was 7.2 days (range 4-41 days). No patient required reoperation during follow-up. Twenty-four patients had acceptable pulmonary valve function, and 6 had clinically well-tolerated moderate or severe pulmonary regurgitation. Ross reversal can be performed with low morbidity and acceptable pulmonary valve function, reducing patient risk of losing 2 native valves when the autograft fails in the aortic position.

Bariatric surgery, especially in the morbidly obese, can be associated with serious postoperative problems. Apart from surgical complications requiring reoperation, pre-existing disease can worsen during the postoperative period. Bariatric patients require particular therapeutic approaches such as adapted fluid and pain management, management of obstructive sleep apnoea-hypopnea, early ambulation and measures for preventing pressure ulcers. Another challenging issue is the early identification and management of postoperative intraabdominal sepsis (IAS) before the onset of organ dysfunction. Early and frequent ambulation is thought to reduce risk of pressure ulcers, deep vein thrombosis, resedation, pain, pneumonia and atelectasis. To prevent spine injury of health care workers it is necessary to provide appropriate support with special beds, lifting and transfer devices.

Controversy persists regarding the use of protamine during carotid endarterectomy (CEA) based on prior conflicting reports documenting both reduced bleeding as well as increased stroke risk. The purpose of this study was to determine the effect of protamine reversal of heparin anticoagulation on the outcome of CEA in a contemporary multistate registry. We reviewed a prospective regional registry of 4587 CEAs in 4311 patients performed by 66 surgeons from 11 centers in Northern New England from 2003-2008. Protamine use varied by surgeon (38% routine use, 44% rare use, 18% selective use). Endpoints were postoperative bleeding requiring reoperation as well as potential thrombotic complications, including stroke, death, and myocardial infarction (MI). Predictors of endpoints were determined by multivariate logistic regression after associated variables were identified by univariate analysis. Of the 4587 CEAs performed, 46% utilized protamine, while 54% did not. Fourteen patients (0.64%) in the protamine-treated group required reoperation for bleeding compared with 42 patients (1.66%) in the untreated cohort (P = .001). Protamine use did not affect the rate of MI (1.1% vs 0.91%, P = .51), stroke (0.78% vs 1.15%, P = .2), or death (0.23% vs 0.32%, P = .57) between treated and untreated patients, respectively. By multivariate analysis, protamine (odds ratio [OR] 0.32, 95% confidence interval [CI], 0.17-0.63; P = .001) and patch angioplasty (OR 0.46, 95% CI, 0.26-0.81; P = .007) were independently associated with diminished reoperation for bleeding. A single center was associated with a significantly higher rate of reoperation for bleeding (OR 6.47, 95% CI, 3.02-13.9; P < .001). Independent of protamine use, consequences of reoperation for bleeding were significant, with a four-fold increase in MI, a seven-fold increase in stroke, and a 30-fold increase in death. Protamine reduced serious bleeding requiring reoperation during CEA without increasing the risk of MI, stroke

Because mitral valve dysfunction in adults with Marfan syndrome is poorly characterized, this study compares mitral valve pathophysiology and morphology with that of myxomatous mitral disease, documents types of mitral valve operations, and assesses long-term survival and durability of mitral valve surgery in Marfan patients. From May 1975 to June 2000, 27 adults with Marfan syndrome underwent mitral valve surgery. Their valve pathophysiology and morphology was compared with that of 119 patients with myxomatous mitral disease undergoing surgery from September 1995 to March 1999. Survival and repair durability were assessed at follow-up. Compared with myxomatous disease patients, Marfan patients had less posterior leaflet prolapse (44% versus 70%, p = 0.01), more bileaflet (44% versus 28%, p = 0.09) and anterior leaflet prolapse (11% versus 3%, p = 0.07), and presented earlier for surgery (age 41 +/- 12 years versus 57 +/- 13, p Marfan patients had longer and thinner leaflets. Mitral valve repair was performed less frequently in Marfan (16 of 27, 59%) than myxomatous disease patients (112 of 119, 94%). There were no hospital deaths; at 10 years, survival was 80% and freedom from reoperation 96%, with only 1 reoperation among the 16 repairs. Mitral valve pathophysiology and morphology differ between Marfan and myxomatous mitral valve diseases. Valve repair in Marfan patients is durable and gives acceptable long-term results, even in adults who present with advanced mitral valve pathology. With increasing use of the modified David reimplantation operation and sparing of the aortic valve, mitral valve repair is a greater imperative, particularly since we have not had to reoperate on any Marfan patients with reimplantations.

Transcatheter valve-in-valve implantation is evolving as an alternative to reoperative valve replacement in high-risk patients with degenerated bioprostheses. Nevertheless, hemodynamic performance is limited by the previously implanted xenograft. We report our experience with patient-prosthesis mismatch (PPM) after valve-in-valve implantation in the aortic position. Eleven patients (aged 79.3 ± 6.1 years) received transapical implantation of a balloon-expandable pericardial heart valve into a degenerated bioprosthesis (size, 23.9 ± 1.6 mm; range, 21-27 mm) in the aortic position. All patients were considered high risk for surgical valve replacement (logistic European System for Cardiac Operative Risk Evaluation, 31.8% ± 24.1%). Severe PPM was defined as an indexed effective orifice area less than 0.65 cm(2)/m(2), determined by discharge echocardiography. Severe PPM was evident in 5 patients (group 1) and absent in 6 patients (group 2). Mean transvalvular gradients decreased from 29.2 ± 15.4 mm Hg before implantation to 21.2 ± 9.7 mm Hg at discharge (group 1) and from 28.2 ± 9.0 mm Hg before implantation to 15.2 ± 6.5 mm Hg at discharge (group 2). Indexed effective orifice area increased from 0.5 ± 0.1 cm(2)/m(2) to 0.6 ± 0.1 cm(2)/m(2) and from 0.6 ± 0.3 cm(2)/m(2) to 0.8 ± 0.3 cm(2)/m(2). Aortic regurgitation decreased from grade 2.0 ± 1.1 to 0.4 ± 0.5 overall. No differences in New York Heart Association class improvement or survival during follow-up were observed. One patient required reoperation for symptomatic PPM 426 days after implantation. Valve-in-valve implantation can be performed in high-risk surgical patients to avoid reoperation. However, PPM frequently occurs, making adequate patient selection crucial. Small bioprostheses (body surface area less than 1.8 m(2). Larger prostheses seem to carry a lower risk for PPM. Although no delay in clinical improvement was seen at short-term, 1 PPM-related surgical intervention raises concern regarding

Although the aortic-valve-sparing (AVS) reimplantation technique according to David has shown favorable durability results in mid-term and long-term studies, composite valve grafting (CVG) according to Bentall is still considered the standard procedure. Retrospectively, we evaluated the results of aortic root replacement of patients with Marfan syndrome (MFS) who underwent surgery between January 1995 and January 2010. MFS was diagnosed using the Ghent criteria. AVS was used in 58 patients and CVG in 30 patients with MFS. AVS was done for aortic-root aneurysm (n=48) or aortic dissection type A (n=10). CVG was used for aortic-root aneurysm in 14 patients or aortic dissection type A in 16 patients. The mean follow-up was 3.2 (95% CI: 2.4-4.2) years. In both groups, 30-day mortality was 0%. Three patients (10.0%) in the CVG group required resternotomy for postoperative bleeding versus two patients (3.4%) in the AVS group (p=0.3). At follow-up, mortality was 10% in the CVG group versus 3.4% in the AVS group (p=0.3). Re-operation was required in two patients (3.4%) after AVS and in three patients after CVG (10%) (p=0.3). Three patients (10.0%) who underwent CVG had endocarditis and two patients (6.7%) had a stroke during follow-up, whereas no endocarditis and stroke occurred after AVS. After 14 years, stratified event-free survival was better in the AVS group (event-free survival was 82.3% vs 58.6%, log-rank test p=0.086), especially after aneurysm (p=0.057). After 10 years, freedom from aortic regurgitation ≥II° in the AVS group was 80% for aneurysm and 50% after dissection (p=0.524). The reimplantation technique according to David was associated with excellent survival, good valve function and a low rate of re-operation, endocarditis, and stroke.

Complex fistulas of the duodenum and biliary tree are severe complications of gastric surgery. The association of duodenal and major biliary fistulas occurs rarely and is a major challenge for treatment. They may occur during virtually any kind of operation, but they are more frequent in cases complicated by the presence of difficult duodenal ulcers or cancer, with a mortality rate of up to 35%. Options for treatment are many and range from simple drainage to extended resections and difficult reconstructions. Conservative treatment is the choice for well-drained fistulas, but some cases require reoperation. Very little is known about reoperation techniques and technical selection of the right patients. We present the case of a complex iatrogenic duodenal and biliary fistula. A 42-year-old Caucasian man with a diagnosis of postoperative peritonitis had been operated on 3 days earlier; an antrectomy with a Roux-en-Y reconstruction for stenotic peptic disease was performed. Conservative treatment was attempted with mixed results. Two more operations were required to achieve a definitive resolution of the fistula and related local complications. The decision was made to perform a pancreatoduodenectomy with subsequent reconstruction on a double jejunal loop. The patient did well and was discharged on postoperative day 17. In our experience pancreaticoduodenectomy may be an effective treatment of refractory and complex iatrogenic fistulas involving both the duodenum and the biliary tree.

Little information exists on the use of continent urinary reservoirs in patients with previous pelvic irradiation. We report the use of the Indiana pouch urinary reservoir in ten women with a history of pelvic irradiation for cervical cancer, of whom eight underwent a total pelvic exenteration for recurrent pelvic tumor and two had diversion for radiation-induced vesicovaginal fistula. All ten women achieved daytime continence, with a median time between catheterizations of 4.5 hours and a median pouch capacity of 500 mL. There was no evidence of leakage from the reservoir or significant ureteral reflux or obstruction on postoperative radiographic evaluation. No patient has required reoperation or had significant postoperative complications with the technique described

Despite the positive clinical results of valve-sparing aortic root replacement, little is known about the causes of reoperations and the modes of failure. From October 1999 to June 2010, 101 patients underwent valve-sparing aortic root replacement using the David reimplantation technique. The definition of aortic root repair failure included the following: (1) intraoperative conversion to the Bentall procedure; (2) reoperation performed because of aortic regurgitation; and (3) aortic regurgitation equal to or greater than a moderate degree at the follow-up. Sixteen patients were considered to have repair failure. Three patients required intraoperative conversion to valve replacement, 3 required reoperation within 3 months, and another 8 required reoperation during postoperative follow-up. At initial surgery 5 patients had moderate to severe aortic regurgitation, 6 patients had acute aortic dissections, 3 had Marfan syndrome, 2 had status post Ross operations, 3 had bicuspid aortic valves, and 1 had aortitis. Five patients had undergone cusp repair, including Arantius plication in 3 and plication at the commissure in 2. The causes of early failure in 6 patients included cusp perforation (3), cusp prolapse (3), and severe hemolysis (1). The causes of late failure in 10 patients included cusp prolapse (4), commissure dehiscence (3), torn cusp (2), and cusp retraction (1). Patients had valve replacements at a mean of 23 ± 20.9 months after reimplantation and survived. Causes of early failure after valve-sparing root replacement included technical failure, cusp lesions, and steep learning curve. Late failure was caused by aortic root wall degeneration due to gelatin-resorcin-formalin glue, cusp degeneration, or progression of cusp prolapse. Copyright © 2011 The Society of Thoracic Surgeons.

Treatment of left-sided colorectal anastomotic leaks often requires fecal stream diversion for prevention of further septic complications. To manage anastomotic leak, it is unclear if diverting ileostomy provides similar outcomes to Hartmann resection with colostomy. We identified all patients who developed anastomotic leak following left-sided colorectal resections from 1/2012 through 12/2014 using the American College of Surgeons National Surgical Quality Improvement Program. Then, we examined the risk of mortality and abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection. There were 1745 patients who experienced an anastomotic leak in a cohort of 63,748 patients (3.7%). Two hundred thirty-five patients had a reoperation for anastomotic leak involving the formation of a diverting ileostomy (n = 77) or Hartmann resection (n = 158). There was no difference in mortality or abdominal reoperation in patients treated with diverting ileostomy (3.9, 7.8%) versus Hartmann resection (3.8, 6.3%) (p = 0.8). There was no difference in the outcomes of mortality or need for second abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection for left-sided colorectal anastomotic leak. Thus, select patients with left-sided colorectal anastomotic leaks may be safely managed with diverting ileostomy.

Results: There were 2 perioperative deaths (2%. One patient developed sternal dehiscence requiring rewiring. Median ICU and hospital stay was 1 and 7 days respectively. Postoperative echocardiography at 6 and 12 months showed excellent bioprosthetic valve performance, significant decrease in size of the right cardiac chambers and reduction of tricuspid regurgitation (TR in the majority of the patients. At mean follow-up of 3.6 ± 2 years, all surviving patients remain in excellent clinical condition. Conclusion: Probability of reoperation for pulmonary insufficiency in patients with surgically corrected TOF increases with time and timely PVR by preventing the development of right heart failure is crucial for long-term survival. Current bioprosthetic valve technology in combination with the beating heart technique provides excellent immediate and short-term results. Further follow-up is necessary to evaluate long-term outcome.

Full Text Available OBJECTIVE: For a cohort of patients with congenital mitral stenosis (CMS, to determine: patient outcomes, predictors of valve repairability and predictors of durability of valve repair. METHODS: From 1989 and 2002, 23 patients underwent surgical treatment of CMS, excluding those with common atrioventricular canal, and univentricular forms. The median age at operation was 15.5 months (range 2-204, and the median body weight was 11 Kg (range 4.5-51.6. Seventeen patients (73.9% had associated anomalies, including Shone's complex in nine (39.1% and pulmonary hypertension in 14 (60.9%. Mitral stenosis was severe in 14 patients (60.9% and moderate in the remaining (median trans-mitral gradient of 16 mmHg, range 8.5-32. Mitral valve repair was performed in 18 patients (78.3%, and valve replacement in five (21.7%. Repair techniques included papillary muscle splitting (n=10, excision of supravalvular ring (n=9 and commissurotomy (n=8. Twelve patients (52.2% required associated procedures. RESULTS: There were no early and late deaths at a mean follow-up of 58.5 ± 46.7 months (range 1-156. Mean hospital stay was 12.7 ± 8.2 days. There were no significant factors associated with unsuccessful valve repair. Actuarial freedom from reoperation at five years was 67.1% (CI 95%: 56.8% to 77.4%. The mitral valve repair group required reoperation in eight patients (44.4% (two early and six late, as opposed to one (20% in the replacement group. The presence of preoperative pulmonary hypertension was significantly related (p<0.005 to higher reoperation rates. All but two the followed patients are presently in functional class I and the echocardiography has shown less than 2+ mitral stenosis and/or regurgitation. CONCLUSION: Reoperations were the most important cause of morbidity at the medium-term follow-up of CMS. Preoperative pulmonary hypertension may predict the need for reoperation after mitral valve repair, which is the procedure of choice in CMS.

Background and purpose - The treatment of patients between 55 and 70 years with displaced intracapsular femoral neck fracture remains controversial. We compared internal fixation (IF), bipolar hemiarthroplasty (HA) and total hip arthroplasty (THA) in terms of mortality, reoperations and patient-reported outcome by using data from the Norwegian Hip Fracture Register. Patients and methods - We included 2,713 patients treated between 2005 and 2012. 1,111 patients were treated with IF, 1,030 with HA and 572 patients with THA. Major reoperations (defined as re-osteosynthesis, secondary arthroplasty, exchange, or removal of prosthesis components and Girdlestone procedure), patient-reported outcome measures (satisfaction, pain, and health-related quality of life (EQ5D) after 4 and 12 months), 1-year mortality, and change in treatment methods over the study period were investigated. Results - Major reoperations occurred in 27% after IF, 3.8% after HA and 2.8% after THA. 549 patients (20% of total study population) answered both questionnaires. Compared with IF, patients treated with THA were more satisfied after 4 and 12 months, reported less pain after 4 months and 12 months, had a higher EQ5D-index score after 4 months and 12 months, and EQ-VAS score after 4 months. Compared with IF, patients treated with HA were more satisfied and reported less pain after 4 months. EQ5D-index and EQ-VAS were similar. Patients treated with HA had higher 1-year mortality and had more comorbidities than both the THA and IF group. All these differences were statistically and clinically significant. Interpretation - This study showed high reoperation rate after IF and better patient-reported outcome after both THA and HA with medium follow-up. Patients selected for HA represented a frailer group than patients treated with THA or IF.

Background The long-term outcomes of aortic valve sparing (AVS) root replacement in Marfan syndrome (MFS) patients remain uncertain. We sought to determine the utilization and outcomes of AVS root replacement in MFS patients enrolled in the Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC). Methods At the time of this analysis, 788 patients with MFS were enrolled in the GenTAC Registry, of whom 288 have undergone aortic root replacement. Patients who have undergone AVS procedures were compared to those who have undergone aortic valve replacing (AVR) procedures. Results AVS root replacement was performed in 43.5% of MFS patients and the frequency of AVS increased over the past 5 years. AVS patients were younger at the time of surgery (31.0 vs. 36.3 years, p=0.006) and more likely to have had elective rather than emergency surgery compared to AVR patients. AVR patients were more likely to have had aortic valve dysfunction and aortic dissection as a primary indication for surgery. After mean follow-up of 6.2 (SD=3.6) years, none of the 87 AVS patients have required reoperation; in contrast, after mean follow up of 10.5 (SD=7.6) years, 11.5% of AVR patients have required aortic root reoperation. Aortic valve function has been durable with 95.8% of AVS patients with aortic insufficiency graded as mild or less. Conclusions AVS root replacement is performed commonly in the MFS population. The durability of the aortic repair and aortic valve function have been excellent to date. These results justify the continued use of the procedure in the elective setting. The GenTAC Registry will be a useful resource to assess the long-term durability of AVS root replacement in the future. PMID:25296451

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 %).

2018-01-01

During the management of critical illness, optimal nutritional support is an important key for achieving positive clinical outcomes. Compared to healthy people, critically ill patients have higher energy expenditure, thereby their energy requirements and risk of malnutrition being increased. Assessing individual nutritional requirement is essential for a successful nutritional support, including the adequate energy supply. Methods to assess energy requirements include indirect calorimetry (IC) which is considered as a reference method, and the predictive equations which are commonly used due to the difficulty of using IC in certain conditions. In this study, a literature review was conducted on the energy metabolic changes in critically ill patients, and the implications for the estimation of energy requirements in this population. In addition, the issue of optimal caloric goal during nutrition support is discussed, as well as the accuracy of selected resting energy expenditure predictive equations, commonly used in critically ill patients.

Because of its durability, the mechanical valve is typically chosen for young patients undergoing mitral valve replacement (MVR). However, a bioprosthetic valve might have the benefit of valve-in-valve transcatheter valve replacement when valve failure occurs. We examined the outcomes in patients who had undergone mechanical valve MVR (MVRm) versus bioprosthetic valve MVR (MVRb) in patients aged Security Death Index. The postoperative and long-term outcomes of interest included combined stroke and embolic events, reoperations, and mortality. Of 768 consecutive patients, 627 were in the MVRm and 141 in the MVRb group. Propensity score matching yielded a cohort of 125 MVRb (89%) and 125 control MVRm patients with similar etiology mixes. The groups were similar in age (MVRm, 53.2 ± 9.0 years; MVRb, 53.8 ± 10.6 years; P = .617) and other preoperative characteristics. The postoperative outcomes were also similar between the 2 groups, including reoperation for bleeding, stroke, deep sternal infection, sepsis, and length of hospital stay. The operative mortality was also similar (MVRm, 5.6%; MVRb, 8.0%; P = .617). However, Kaplan-Meier analysis showed the MVRb group had a greater reoperation rate (P = .001) and shorter estimated survival (11.3 vs 13.5 years, P = .004). The incidence of bleeding and stroke or embolic events between the 2 groups was similar. In the present report, MVRb for patients safety of mechanical valves in this group.

Few studies discuss causes and outcomes of peritonitis in low-income settings. This study describes epidemiology of patients with peritonitis at a Rwandan referral hospital. Identification of risk factors associated with mortality and unplanned reoperation could improve management of peritonitis. Data were collected on demographics, clinical presentation, operative findings, and outcomes for all patients with peritonitis. Multivariate regression analysis identified factors associated with in-hospital mortality and unplanned reoperation. A total of 280 patients presented with peritonitis over a 6-month period. Causes of peritonitis were complications of intestinal obstruction (39%) and appendicitis (17%). Thirty-six (13%) patients required unplanned reoperation, and in-hospital mortality was 17%. Factors associated with increased odds of in-hospital mortality were unplanned reoperation (adjusted odds ratio 34.12), vasopressor use (adjusted odds ratio 24.91), abnormal white blood cell count (adjusted odds ratio 12.6), intensive care unit admission (adjusted odds ratio 9.06), and American Society of Anesthesiologist score ≥3 (adjusted odds ratio 7.80). Factors associated with increased odds of unplanned reoperation included typhoid perforation (adjusted odds ratio 5.92) and hypoxia on admission (adjusted odds ratio 3.82). Peritonitis in Rwanda presents with high morbidity and mortality. Minimizing delays in care is important, as many patients with intestinal obstruction present with features of peritonitis. A better understanding of patient care and management prior to arrival at the referral hospital is needed to identify areas for improvement at the health center and district hospital.

This prospective study aimed to compare outcomes after laparoscopic peritoneal lavage (LPL) and sigmoid resection with primary colorectal anastomosis (RPA). From June 2010 to June 2015, 40 patients presenting with Hinchey III peritonitis from perforated diverticulitis underwent LPL or RPA. Patients with Hinchey II or IV peritonitis and patients who underwent an upfront Hartmann procedure were excluded. Primary endpoint was overall 30-day or in-hospital postoperative morbidity after surgical treatment of peritonitis. Twenty-five patients underwent RPA and 15 LPL. Overall postoperative morbidity and mortality rates were not significantly different after RPA and LPL (40 vs 67 %, p = 0.19; 4 vs 6.7 %, p = 1, respectively). Intra-abdominal morbidity and reoperation rates were significantly higher after LPL compared to RPA (53 vs 12 %, p < 0.01; 40 vs 4 %, p = 0.02, respectively). Multivariate analysis showed that LPL (p = 0.028, HR = 18.936, CI 95 % = 1.369-261.886) was associated with an increased risk of postoperative intra-abdominal septic morbidity. Among 6 patients who underwent reoperation after LPL, 4 had a Hartmann procedure. All surviving patients who had a procedure requiring stoma creation underwent stoma reversal after a median delay of 92 days after LPL and 72 days after RPA (p = 0.07). LPL for perforated diverticulitis is associated with a high risk of inadequate intra-abdominal sepsis control requiring a Hartmann procedure in up to 25 % of patients. RPA appears to be safer and more effective. It may represent the best option in this context.

A well-functioning rotator cuff is necessary for successful anatomic total shoulder arthroplasty (TSA). This study evaluated patients who underwent concomitant TSA and rotator cuff repair (RCR) for functional outcomes, revision rates, and predictors of poor results. Retrospective chart review was conducted to identify patients who underwent TSA and RCR. Demographic data, rotator cuff tear and RCR characteristics, range of motion, and radiographs were recorded. Minimum 2-year functional outcomes were obtained. Predictors of reoperation and/or poor clinical results were determined. Forty-five patients met inclusion criteria (22 high-grade partial-thickness and 23 full-thickness tears). Fourteen (31%) patients were labeled as having a poor result; 8 (18%) patients required reoperation. There was a significant difference between the acromiohumeral interval preoperatively and immediately postoperatively (P=.013). However, at maximum radiographic follow-up, the acromiohumeral interval was not significantly different from preoperative values (P=.86). Patients with a preoperative acromiohumeral interval of less than 8 mm had an increased rate of cuff-related reoperation (P=.003). Although concomitant TSA and RCR is a reasonable consideration, 31% of patients had a poor clinical result. An acromiohumeral interval of less than 8 mm was a predictor of cuff-related reoperation and may be an indication to consider reverse arthroplasty in the setting of joint arthrosis with a rotator cuff tear.

Intramedullary nailing is commonly recommended as the treatment of choice for transverse/reverse oblique trochanteric (AO/OTA type A3=intertrochanteric) and subtrochanteric fractures. However, only to a limited extent is this approach supported by superior results in well designed clinical trials, and the sliding hip screw (SHS) is still a frequently used implant for these fractures. The aim of the present study was to compare IM nails and SHS in the treatment of transverse/reverse oblique trochanteric and subtrochanteric fractures using data from the Norwegian Hip Fracture Register (NHFR). Data on 2716 operations for acute transverse/reverse oblique trochanteric or subtrochanteric fractures were collected from the NHFR from 2005 to 2010. Surgeons reported patient characteristics and details from initial surgery and reoperations, and patients answered questionnaires about pain, satisfaction, and quality of life (EQ-5D) 4, 12, and 36 months postoperatively. Reoperation rates were calculated using Kaplan-Meier analyses. Primary outcome measures were pain (Visual Analogue Scale (VAS)), satisfaction (VAS), quality of life (EQ-5D), and reoperation rates at one year. The treatment groups were similar regarding age, gender, ASA-class, cognitive impairment, and preoperative EQ-5Dindex score. At one year reoperation rates were 6.4% and 3.8% for SHS and IM nails, respectively (p=0.011). Patients treated with SHS also had slightly more pain (VAS 30 vs. 27, p=0.037) and were less satisfied (VAS 31 vs. 36, p=0.003) compared to patients treated with IM nail. There was no statistically significant difference in the EQ-5Dindex score, but the mobility was significantly better for the IM nail group. 12 months postoperatively patients with transverse/reverse oblique trochanteric and subtrochanteric fractures operated with a SHS had a higher reoperation rate compared to those operated with an IM nail. Small differences regarding pain, satisfaction, quality of life, and mobility were

From 1991 through 2001, 21 Marfan patients underwent aortic operations in our hospital. They received a total of 36 aortic operations, 31 by ourselves including 4 non-elective operations and 2 operations before 1991. Extent of replacement was Bentall + total arch (4), Bentall (8), valve sparing aortic root (reimplantation) (2), re-anastomosis + coronary aortic bypass grafting (CABG) after Bentall (1), ascending + total arch (3), ascending (1), total arch (1), total thoracoabdominal (10), thoracoabdominal (1), descending thoracic (2), distal arch (1), abdominal (2). Multiple operations were required in 11 patients (2 operations in 7, 3 operations in 4). Eight reoperations in 6 patients were for adjacent lesion, 5 reoperations were for remote lesion, and 2 others were for complication of Bentall (initial operation elsewhere). Among the 8 reoperations for adjacent lesion, 3 were scheduled operation (2 with elephant trunk), 4 were for residual dissection, and 1 was for annulo-aortic ectasia (AAE). Total aortic replacement was achieved in 4 and subtotal replacement excluding the root in 2. There was no hospital mortality. Paraparesis occurred in 1 who died 4.7 years after operation. The remaining patients are currently alive. No other aortic event occurred. Aortic reoperation-free survival was 83% at 5 year and 28% at 10 year.

OBJECT.: While transsphenoidal surgery is associated with low morbidity, the degree to which morbidity increases after reoperation remains unclear. The authors determined the morbidity associated with repeat versus initial transsphenoidal surgery after 1015 consecutive operations. The authors conducted a 5-year retrospective review of the first 916 patients undergoing transsphenoidal surgery at their institution after a pituitary center of expertise was established, and they analyzed morbidities. The authors analyzed 907 initial and 108 repeat transsphenoidal surgeries performed in 916 patients (9 initial surgeries performed outside the authors' center were excluded). The most common diagnoses were endocrine inactive (30%) or active (36%) adenomas, Rathke's cleft cysts (10%), and craniopharyngioma (3%). Morbidity of initial surgery versus reoperation included diabetes insipidus ([DI] 16% vs 26%; p = 0.03), postoperative hyponatremia (20% vs 16%; p = 0.3), new postoperative hypopituitarism (5% vs 8%; p = 0.3), CSF leak requiring repair (1% vs 4%; p = 0.04), meningitis (0.4% vs 3%; p = 0.02), and length of stay ([LOS] 2.8 vs 4.5 days; p = 0.006). Of intraoperative parameters and postoperative morbidities, 1) some (use of lumbar drain and new postoperative hypopituitarism) did not increase with second or subsequent reoperations (p = 0.3-0.9); 2) some (DI and meningitis) increased upon second surgery (p = 0.02-0.04) but did not continue to increase for subsequent reoperations (p = 0.3-0.9); 3) some (LOS) increased upon second surgery and increased again for subsequent reoperations (p surgery (p = 0.3) but went on to increase upon subsequent reoperations (p = 0.001-0.02). Multivariate analysis revealed that operation number, but not sex, age, pathology, radiation therapy, or lesion size, increased the risk of CSF leak, meningitis, and increased LOS.

Autograft dilatation is the main long-term complication following the Ross procedure using the freestanding root replacement technique. We reviewed our 25-year experience with the Ross procedure with a special emphasis on valve-sparing reoperations. From 1991 to 2016, 153 patients (29.6 ± 16.6 years; 29.4% pediatric) underwent a Ross operation at our institution with implantation of the autograft as freestanding root replacement. The follow-up is 98.7% complete with a mean of 12.2 ± 5.5 years. Mortality at 30-days was 2.0%. Echocardiography documented no or trivial aortic regurgitation in 99.3% of the patients at discharge. Survival probability at 20 years was 85.4%. No case of autograft endocarditis occurred. Autograft deterioration rate was 2.01% per patient-year, and freedom from autograft reoperation was 75.3% at 15 years. A reoperation for autograft aneurysm was required in 35 patients (22.9%) at a mean interval of 11.1 ± 4.6 years after the Ross procedure. A valve-sparing root replacement was performed in 77% of patients, including 10 David and 17 Yacoub procedures with no early mortality. Three patients required prosthetic valve replacement within 2 years after a Yacoub operation. At latest follow-up, 92% of all surviving patients still carry the pulmonary autograft valve. Freedom from autograft valve replacement was 92.1% at 15 years. Using the David or Yacoub techniques, the autograft valve can be preserved in the majority of patients with root aneurysms after the Ross procedure. Reoperations can be performed with no early mortality, a good functional midterm result, and an acceptable reintervention rate. Copyright © 2018 The American Association for Thoracic Surgery.

Full Text Available Background: Mitral regurgitation is one of the leading causes of cardiovascular morbidity in pediatric patients with Marfan syndrome. The purpose of this study was to contribute to determining the appropriate surgical strategy for these patients. Methods: From January 1992 to May 2013, six patients with Marfan syndrome underwent surgery for mitral regurgitation in infancy or early childhood. Results: The median age at the time of surgery was 47 months (range, 3 to 140 months and the median follow-up period was 3.6 years (range, 1.3 to 15.5 years. Mitral valve repair was performed in two patients and four patients underwent mitral valve replacement with a mechanical prosthesis. There was one reoperation requiring valve replacement for aggravated mitral regurgitation two months after repair. The four patients who underwent mitral valve replacement did not experience any complications related to the prosthetic valve. One late death occurred due to progressive emphysema and tricuspid regurgitation. Conclusion: Although repair can be an option for some patients, it may not be durable in infantile-onset Marfan syndrome patients who require surgical management during infancy or childhood. Mitral valve replacement is a feasible treatment option for these patients.

Although there have been reports of single-surgeon outcomes with highly cohesive, form-stable silicone gel implants in women undergoing primary breast augmentation, there has been only one study published that compares the outcomes between the Allergan 410 and the Mentor CPG devices. The goal of the study is to compare outcomes in each cohort and to determine if quality systems and processes would have an impact on lowering the surgical revision rate, as compared to published reports for round gel implants and form-stable implants. Patients selected for the study were required to meet predefined inclusion criteria and general indications for breast augmentation. All subjects were treated uniformly with extensive informed consent prior to surgery. The entire process of breast augmentation (patient assessment, informed consent, the surgical procedure itself and postoperative instructions) was identical between the two groups. Patients were not randomized, as the studies did not start at the same time. The process for management of each patient was based on adaptation of the Toyota Production System and Lean Manufacturing, with emphasis on achieving operational excellence in the use of planning templates for surgery, including accurate management of patient expectations regarding size outcome. Outcomes data included physical breast measurements, quality of life metrics, and patient/surgeon satisfaction assessment. Adverse events were compared against published data for breast implants. Follow-up ranged between 20-77 months (Allergan 410) and 16-77 months (Mentor CPG). The outcome data indicate that these devices produce natural-appearing breasts with extremely low aggregate reoperation rate (4.2%). Only 0.8% of the reoperations were attributable to surgeon-related factors. There were no reoperations to correct mismanaged size expectations during the course of each study. There were 13 pregnancies and no difficulties with lactation were reported. Rippling (lateral

Association between biomarkers and clinical characteristics in chronic subdural hematoma patients assessed with lasso regression.

Full Text Available Chronic subdural hematoma (CSDH is characterized by an "old" encapsulated collection of blood and blood breakdown products between the brain and its outermost covering (the dura. Recognized risk factors for development of CSDH are head injury, old age and using anticoagulation medication, but its underlying pathophysiological processes are still unclear. It is assumed that a complex local process of interrelated mechanisms including inflammation, neomembrane formation, angiogenesis and fibrinolysis could be related to its development and propagation. However, the association between the biomarkers of inflammation and angiogenesis, and the clinical and radiological characteristics of CSDH patients, need further investigation. The high number of biomarkers compared to the number of observations, the correlation between biomarkers, missing data and skewed distributions may limit the usefulness of classical statistical methods. We therefore explored lasso regression to assess the association between 30 biomarkers of inflammation and angiogenesis at the site of lesions, and selected clinical and radiological characteristics in a cohort of 93 patients. Lasso regression performs both variable selection and regularization to improve the predictive accuracy and interpretability of the statistical model. The results from the lasso regression showed analysis exhibited lack of robust statistical association between the biomarkers in hematoma fluid with age, gender, brain infarct, neurological deficiencies and volume of hematoma. However, there were associations between several of the biomarkers with postoperative recurrence requiring reoperation. The statistical analysis with lasso regression supported previous findings that the immunological characteristics of CSDH are local. The relationship between biomarkers, the radiological appearance of lesions and recurrence requiring reoperation have been inclusive using classical statistical methods on these data

Full Text Available BackgroundSurgery in combination with radiotherapy (RT has become the standard of care for most soft tissue sarcomas. The choice between pre- and postoperative RT is controversial. Preoperative RT is associated with a 32–35% rate of major wound complications (MWC and 16–25% rate of reoperation. The role of vascularized soft tissue “flaps” in reducing complications is unclear. We report the outcomes of patients treated with preoperative RT, resection, and flap reconstruction.Patients and methods122 treatment episodes involving 117 patients were retrospectively reviewed. All patients were treated with 50.4 Gy of external beam radiation. Surgery was performed at 4–8 weeks after completion of RT by the same combination of orthopedic oncology and plastic reconstructive surgeon. Defects were reconstructed with 64 free and 59 pedicled/local flaps.Results30 (25% patients experienced a MWC and 17 (14% required further surgery. 20% of complications were exclusively related to the donor site. There was complete or partial loss of three flaps. There was no difference in the rate of MWC or reoperation for complications with respect to age, sex, tumor site, previous unplanned excision, tumor grade, depth, and type of flap. Tumor size ≥8 cm was associated with a higher rate of reoperation (11/44 vs 6/78; P = 0.008 but the rate of MWC was not significant (16/44 vs 14/78; P = 0.066.ConclusionThe use of soft tissue flaps is associated with a low rate of MWC and reoperation. Our results suggest that a high rate of flap usage may be required to observe a reduction in complication rates.

Risk Factors for Reoperation and Performance-Based Outcomes After Operative Fixation of Foot Fractures in the Professional Athlete: A Cross-Sport Analysis.

Science.gov (United States)

Singh, Sameer K; Larkin, Kevin E; Kadakia, Anish R; Hsu, Wellington K

Professional athletes are predisposed to fractures of the foot due to large stresses placed on the lower extremity. These players are concerned with efficiently returning to play at a high level. Return-to-play rates after operative treatment have been previously reported, yet performance outcomes after such treatment are generally unknown in this population. Overall, professional athletes sustaining a foot fracture would return to play at high rates with little impact on postoperative performance or league participation. However, National Football League (NFL) athletes would have a significantly greater decline in performance due to the high-impact nature of the sport. Case series. Level 4. Athletes in the National Basketball League (NBA), NFL, Major League Baseball (MLB), and National Hockey League (NHL) undergoing operative fixation of a foot fracture were identified through a well-established protocol confirmed by multiple sources of the public record. Return-to-play rate and time to return were collected for each sport. League participation and game performance data were collected before and after surgery. Statistical analysis was performed, with significance accepted as P ≤ 0.05. A total of 77 players undergoing 84 procedures met the inclusion criteria. Overall, 98.7% (76/77) of players were able to return to play, with a median time to return across all sports of 137 days. Players returned to preoperative performance levels within 1 season of surgery. Six players (7.8%) sustained refracture requiring reoperation, all of whom were in the NBA. Percentage of games started during the season after primary operative treatment was a predictive factor for reinjury (99% vs 40%, P = 0.001). Athletes returned to play at a high rate after foot fracture fixation, with excellent postoperative performance levels, regardless of sport and fracture location. NBA athletes sustaining fifth metatarsal and navicular fractures are at greater risk of reinjury compared with other

We report our experience with aortic valve-sparing procedures in patients with Marfan syndrome and aortic root aneurysm. Between August 2003 and July 2007, we performed aortic valve-sparing procedures in 20 patients with aortic root aneurysm resulting from Marfan syndrome. Mean age was 28 +/- 10 years (range, 10 to 57 years), and there were 9 females and 11 males. A reimplantation technique was used in 9 cases, a remodeling technique in 8 and a patch technique in 3 cases. Additional procedures included total aorta replacement in 1 patient, and aortic arch replacement plus stented elephant trunk in 2 patients. The mean follow-up time was 46 +/- 16 months (range, 17 to 64 months). No in-hospital or late death occurred. Reexploration for bleeding was required in one case on postoperative day 1. No valve-related complications occurred during the follow-up period. At the end of follow-up, trivial or no aortic regurgitation was demonstrated in 14 patients, mild in 4 patients, moderate in 1 and severe in 1. Two patients with moderate and severe aortic regurgitation required reoperation. The early and mid-term results of the valve-sparing operations were favorable, and the durability of the preserved valve should encourage use of this technique in patients with Marfan syndrome.

The current prospective study aimed at assessing skeletal stability and complications arising from transantral maxillary distraction adopted for advancements of less than 12 mm in patients with cleft lip, alveolus, and palate malformations.The recruited patients with cleft lip, alveolus, and palate were followed up for 12 months. Lateral skull radiographs were obtained before surgery (T0), at the end of the activation period of the distractors (T1), and after completion of the follow-up interval (T2). Length and height of the maxilla were assessed at the different points of time. The relapse rate of maxillary advancement was calculated. Complications such as infections, distractor breakage and loosening, nonunions, and the need for reoperation were documented.Seven patients were included in this study (mean [SD] age, 19.5 [2.6] y). The length of the maxilla significantly increased by 6.4 ± 1.1 mm at T1 (P = 0.018) but showed a significant relapse by 7.5% at T2 (P = 0.018). As a complication, a case of infection of the cheek occurred during the consolidation period, which could be treated conservatively. In an additional patient, there was a loosening of a distractor at the end of the distraction period, which required reoperation with conventional fixation of the maxilla in the intended position. At the time of removal of the distractors and the conventional osteosynthesis plates, no cases of nonunion could be identified.It seems that the low horizontal relapse rate of transantral maxillary distraction in patients with cleft lip and palate outweighs the possible complications of this procedure in cases of limited distances of advancement of less than 12 mm.

Operative repair of obstructive gastric volvulus is challenging. In high-operative risk patients with obstructive gastric volvulus, we perform laparoscopic reduction of gastric volvulus and anterior abdominal wall sutured gastropexy. This case series reports our experience with this operation. We reviewed the charts of all patients who presented with obstructive gastric volvulus and underwent laparoscopic gastropexy between 2007 and 2013. Eleven patients underwent laparoscopic gastropexy. Median age was 83 years (50 to 92). Six patients presented with chronic obstruction; 5 presented with acute obstruction. Median postoperative hospitalization was 2 days (1 to 39). Two patients required reoperation for displaced gastrostomy tubes. At median follow-up of 3 months (2 weeks to 57 months), all patients remained free of gastric obstructive symptoms and recurrent episodes of volvulus. Only 1 patient received nutrition via gastrostomy tube. Laparoscopic gastropexy can treat obstructed gastric volvulus in highoperative risk patients. Because of associated morbidity, gastrostomy tubes should be placed selectively. Copyright © 2015 Elsevier Inc. All rights reserved.

Effective design of health information technology (HIT) for patient-centered care requires consideration of workflow from the patient's perspective, termed 'patient-oriented workflow.' This approach organizes the building blocks of work around the patients who are moving through the care system. Patient-oriented workflow complements the more familiar clinician-oriented workflow approaches, and offers several advantages, including the ability to capture simultaneous, cooperative work, which is essential in care delivery. Patient-oriented workflow models can also provide an understanding of healthcare work taking place in various formal and informal health settings in an integrated manner. We present two cases demonstrating the potential value of patient-oriented workflow models. Significant theoretical, methodological, and practical challenges must be met to ensure adoption of patient-oriented workflow models. Patient-oriented workflow models define meaningful system boundaries and can lead to HIT implementations that are more consistent with cooperative work and its emergent features.

The aim of this study was to explore the nature and rate of surgical intervention after transvaginal Prolift mesh repair for pelvic organ prolapse. This was a retrospective study of all patients who underwent Prolift mesh repair between January 2005 and January 2009. Patient data were obtained from medical records, and patients were telephoned to check if they had surgery in other hospitals. A total of 600 consecutive patients were identified. Of these, 524 patients (87.3%) were included in the study, with a median follow-up duration of 38 months (range, 15-63). Global reoperation rate was 11.6%. Indications of intervention were surgery for urinary incontinence (6.9%), mesh-related complications (3.6%), or prolapse recurrence (3%). The global reoperation rate after transvaginal Prolift mesh repair was 11.6%, with urinary incontinence surgery being the most common indication. Rates of mesh complications and prolapse recurrence are relatively low in an experienced team. Copyright © 2012 Mosby, Inc. All rights reserved.

Transverse colon conduit urinary diversion in patients treated with very high dose pelvic irradiation

Ravi, R.; Dewan, A.K.; Pandey, K.K.

1994-01-01

Urinary diversion may be required in patients receiving pelvic irradiation for gynaecological or genitourinary cancers either as part of a planned or salvage surgical procedure or for urological complications of irradiation. Records were reviewed for 30 such patients who underwent transverse colon conduit as a primary form of urinary diversion. Most of the conduits were constructed using refluxing ureterocolic anastomoses with stents. The results showed no operative mortality. Although the procedure was associated with a complication rate of 37% and a re-operation rate of 20%, there were no bowel or urinary anastomotic leaks. The operation could be safely performed on patients with renal failure, with 83% of such patients showing normal or improved serum creatinine levels post operatively. The advantages of transverse colon conduit urinary diversion are the use of non-irradiated bowel and ureters for diversion. It is recommended as a primary form of urinary diversion in these high risk cases. (Author)

Caloric requirement of the critically ill septic patient

International Nuclear Information System (INIS)

Shizgal, H.M.; Martin, M.F.

1988-01-01

The caloric requirement of the critically ill septic patient was determined by measuring body composition, by multiple isotope dilution, before and at 2-wk intervals while receiving total parenteral nutrition (TPN) in 86 septic and 57 nonseptic malnourished patients. All patients received a TPN solution containing 25% dextrose and 2.75% crystalline amino acids. The body composition of the nonseptic patients, who received 51.9 +/- 1.5 kcal/kg.day, improved significantly, while that of the septic patients, receiving 46.8 +/- 1.1 kcal/kg.day was only maintained. The relationship between caloric intake and the restoration of a malnourished body cell mass (BCM) was determined for each group by correlating, using multiple linear regression, the mean daily change in the BCM with the caloric intake and the nutritional state, as determined by body composition. According to the resultant regressions, an intake of 35.1 and 50.7 kcal/kg.day was required to maintain the BCM of the septic and nonseptic patients, respectively. To restore a depleted BCM, caloric intakes in excess of this amount are required

We investigated our surgical strategy and clinical results in patients from active infective endocarditis (AIE) complicated by paravalvular involvement to determine the risk factors of early and late death and reoperation. From October 1979 to December 2014, 955 patients underwent operations for AIE; among them 207 had AIE with paravalvular extension. The patients were a mean age of 59.9 ± 15.4 years, and 162 (78%) were male. Of these patients, 137 (66%) had isolated aortic valve endocarditis, and 138 (67%) had native valve endocarditis. Follow-up was 99% complete. The operative mortality of the cohort was 16% (n = 34). Abnormal communication, mechanical valve implantation, and renal failure were independent predictors of 30-day death. Survival at 1, 5, 10, and 15 years was 90.3% ± 2.3%, 62.4% ± 3.7%, 49.3% ± 4.1%, and 37.9% ± 4.4%, respectively. Streptococcus endocarditis (all species), complex annular repair, and preoperative heart failure were independent predictors of long-term death. A reoperation was required in 29 patients (14%). Streptococcus pneumoniae endocarditis was the only independent predictor of early reoperation (within 30 days after the operation or during the same hospitalization). Freedom from reoperation at 1, 5, 10, and 15 years was 91.9% ± 2.2%, 89.6% ± 2.6%, 89.6% ± 2.6%, and 87.0% ± 3.5%, respectively. Independent predictors of late reoperation were urgent/emergency operation, prosthetic valve endocarditis, and complex annular repair. AIE complicated by paravalvular involvement remains a surgical challenge. Valve replacement (particularly using bioprosthesis) associated with ad hoc reconstruction seems to be a reliable option and showed very encouraging results in this context.

Since 1988, a modified repair technique has been used at the authors' institution to treat patients with Ebstein's anomaly. This technique restructures the valve mechanism at the level of the true tricuspid annulus by using the most mobile leaflet for valve closure, without plication of the atrialized chamber. A total of 19 patients had additional attachment of the anterior right ventricular wall to the interventricular septum (Sebening's stitch) and reconstruction of the tricuspid valve as a double-orifice valve. The long-term results of the study are presented. Between 1988 and 2008, tricuspid valve repair was performed in 50 patients with Ebstein's anomaly (33 females, 17 males; median age 22 years; range: 0.6 to 60 years), at the authors' institution. The median follow up was 68 months (range: 5 to 238) months. Details of the survival rate, reoperations, NYHA class, maximal VO2, right ventricular function (velocity-time integral pulmonary artery (VTI-PA)), and tricuspid valve insufficiency were documented. No patient deaths occurred during surgery; the early mortality was 7.1%, and late mortality 2.4%. Those patients who died were all aged > 50 years, and in NYHA class III or IV. No additional patient deaths have occurred since 2004. Four reoperations were necessary. Both, the NYHA class and tricuspid valve insufficiency were improved significantly (from 3.1 to 1.8; p tricuspid repair, without plication of the right ventricle, even in cases where tricuspid valve replacement was discussed. Modifications seemed to support these results. Surgery in older patients with a progressive NYHA class seemed to carry a higher operative mortality.

Peptic ulcer perforations are a common emergency, but available literature is silent on the exact definition, incidence, management, and complications of peritonitis due to omental patch leakage. Retrospective data were collected on 422 patients who underwent omental patch repair of perforated peptic ulcer between March 20, 1999 and March 20, 2006. The definitive diagnosis of perforated peptic ulcer and omental patch leakage was obtained at surgery. Seventeen (4%) patients experienced generalized peritonitis due to omental patch leakage. Mean age was 60.6 years. Mortality rate was 29.4%, and the mean hospital stay was 23.6 days. Delay in surgical approach, shock on admission, and age were all significantly associated with increased mortality. Peritonitis due to omental patch leakage can result in significant morbidity and mortality. The most common causes of omental patch leakage and operative procedures were unknown and reinsertion of omentum, respectively. Factors such as shock on admission or delayed surgery, have significantly contributed to fatal outcomes and need careful attention.

Postoperative intracranial infectious complications are one of the most topical problems of neurosurgical intensive care due to theirs significant capability to impair outcomes of the main disease. To define the risk factors of postoperative meningitis in patients with chiasm-sellar tumors. 1. to define the effect of somatic and intracranial risk factors on occurrence of postoperative meningitis in patients after transsphenoidal and transcranial approaches to the tumor. 2. To define the effect of postoperative meningitis on outcomes of treatment in patients after transsphenoidal and transcranial approaches to the tumor. Somatic and intracranial risk factors of occurrence of postoperative meningitis (pneumonia, urinary tract infection, sepsis, intra-abdominal hypertension, the presence of external ventricular and lumbar drainage, monitoring of intracranial pressure, cerebrospinal fluid, and reoperation) were fixed every day. The study was conducted in the ICU of the Burdenko from October, 2010 to July, 2012. The 34 patients (19 males, 15 females) were included in the study (average age 47.5 years). The patients were divided into two groups; 17 patients each group. The group-1 included patients after transcranial approach to the tumor and the group-2 included patients after transsphenoidal approach. In the group-1 a meningitis occurred in 3 patients (17.6% +/- 9.2%, DI [-0.4 - 35.6]). In the group-2 a meningitis occurred in 7 patients (41.2% +/- 11.9) DI 95% [17.8 - 64.4]. Accumulation of cerebrospinal fluid under the skin flap authentically increased a risk of a meningitis occurrence in patients after transcranial approach to the tumor (p = 0.031). There was no defined statistical significance of other risk factors. But there was defined a trend of the increasing of meningitis occurrence in patients after transsphenoidal approach in case of lumbar drainage or reoperation. Duration of mechanical ventilation and ICU stay in patients with meningitis was authentically

The study aim was to evaluate the long-term clinical outcomes of the modified Bentall procedure (MBP) with a mechanical conduit. Between 1993 and 2014, a total of 249 patients (mean age 62 ± 12 years; range: 25-87 years) underwent a MBP at the authors' institution. The main indication was annuloaortic ectasia in 102 patients (41%), followed by acute aortic dissection in 82 patients (33%); moderate to severe aortic regurgitation was present in 79% of cases. A bicuspid aortic valve was found in 17% of patients, and Marfan syndrome in 7%. The mean NYHA functional class was 2.5 ± 1.1. Concomitant procedures were performed in 36 patients (14%). The mean follow up was 8.7 ± 5.0 years (range: 0.3-21.5 years) and was 99% complete. The total follow up was 6.475 patient-years (pt-yr). Operative mortality was 3% in elective cases. Age, prolonged cardiopulmonary bypass times and mechanical ventilation >96 h were independent risk factors for early mortality. Actuarial survival at 15 and 20 years was 62% and 60%, respectively. Risk factors for late mortality were age and emergency operation. Actuarial freedom from thromboembolism (linearized incidence 0.93%/pt-yr) was 82% at 15 years, and 74% at 20 years. Seven patients required reoperation (0.38%/pt-yr), with an actuarial freedom from reoperation of 91% at 15 years and 87% at 20 years. The incidence of overall valve-related complications was 0.32%/pt-yr, with actuarial freedoms of 94% at 15 and 20 years. The MBP has shown excellent long-term results with a low incidence of procedure-related complications up to 20 years postoperatively. For this reason, it is considered to be a valid option for the treatment of aortic root disease, whenever valvesparing procedures are not indicated.

Although implementation of temozolomide (TMZ) as a part of primary therapy for glioblastoma multiforme (GBM) has resulted in improved patient survival, the disease is still incurable. Previous studies have correlated various parameters to survival, although no single parameter has yet been identified. More studies and new approaches to identify the best and worst performing patients are therefore in great demand. This study examined 225 consecutive, non-selected GBM patients with performance status (PS) 0–2 receiving postoperative radiotherapy with concomitant and adjuvant TMZ as primary therapy. At relapse, patients with PS 0–2 were mostly treated by reoperation and/or combination with bevacizumab/irinotecan (BEV/IRI), while a few received TMZ therapy if the recurrence-free period was >6 months. Median overall survival and time to progression were 14.3 and 8.0 months, respectively. Second-line therapy indicated that reoperation and/or BEV/IRI increased patient survival compared with untreated patients and that BEV/IRI was more effective than reoperation alone. Patient age, ECOG PS, and use of corticosteroid therapy were significantly correlated with patient survival and disease progression on univariate analysis, whereas p53, epidermal growth factor receptor, and O 6 -methylguanine-DNA methyltransferase expression (all detected by immunohistochemistry), tumor size or multifocality, and extent of primary operation were not. A model based on age, ECOG PS, and corticosteroids use was able to predict survival probability for an individual patient. The survival of RT/TMZ-treated GBM patients can be predicted based on patient age, ECOG PS, and corticosteroid therapy status

A central challenge of integrated water management is the design and implementation of policies to allocate water to both humans and the environment in a sustainable manner. This study uses the results from a reach-scale water-planning model to quantify and compare the economic benefits of two water management policies: (1) a business as usual (Baseline) policy and (2) a proposed reservoir re-operation policy to provide environmental flows (EFs). Results show that the EF policy would increase water supply profit, slightly decrease recreational activities profit, and reduce costs from flood damage and environmental restoration compared to the Baseline policy. In addition to supporting ecological objectives, the proposed EF policy would increase the economic benefits of water management objectives.

Nutritional requirements of the critically ill patient.

Chan, Daniel L

2004-02-01

The presence or development of malnutrition during critical illness has been unequivocally associated with increased morbidity and mortality in people. Recognition that malnutrition may similarly affect veterinary patients emphasizes the need to properly address the nutritional requirements of hospitalized dogs and cats. Because of a lack in veterinary studies evaluating the nutritional requirements of critically ill small animals, current recommendations for nutritional support of veterinary patients are based largely on sound clinical judgment and the best information available, including data from experimental animal models and human studies. This, however, should not discourage the veterinary practitioner from implementing nutritional support in critically ill patients. Similar to many supportive measures of critically ill patients, nutritional interventions can have a significant impact on patient morbidity and may even improve survival. The first step of nutritional support is to identify patients most likely to benefit from nutritional intervention. Careful assessment of the patient and appraisal of its nutritional needs provide the basis for a nutritional plan, which includes choosing the optimal route of nutritional support, determining the number of calories to provide, and determining the composition of the diet. Ultimately, the success of the nutritional management of critically ill dogs and cats will depend on close monitoring and frequent reassessment.

To describe the complications associated with heart surgery, compare them to a reference population, and identify mortality risk factors. Retrospective and descriptive study. All patients who underwent surgery at Hospital Garrahan in the 2013-2015 period were included. Age, weight, procedure, mechanical ventilation, length of stay in days, morbidity, and course were recorded. Renal failure requiring dialysis, neurological deficit, permanent pacemaker, circulatory support, phrenic nerve or vocal cord palsy, reoperation, wound infection, chylothorax, and tracheotomy were considered morbidities. A descriptive, statistical analysis by risk category was done using the Society of Thoracic Surgeons (STS) morbidity score. 1536 patients, median age: 12 months (interquartile range [IQR] 25-75: 3-60), weight: 8 kg (IQR 25-75: 4.4 to 17.5), mortality: 5%. A total of 361 events were recorded in 183 patients. An unplanned reoperation was the most common event (7.2%); the rest occurred in < 3% of patients. Compared to patients without complications, patients who had events required more days on mechanical ventilation: 9.95 (IQR 25-75: 7.6512.24) versus 1.8 (IQR 2575: 1.46-2.14), p< 0.00001; a longer length of stay: 28.8 (IQR 25-75: 25.1-32.5) versus 8.5 (IQR 25-75: 7.9-9.2), p< 0.0001; and had a higher mortality: 19.6% versus 3.1% (RR: 4.58, 95% CI: 3.4 to 6.0), p< 0.0001. Circulatory support and renal failure were associated with a higher mortality. An unplanned reoperation was the most common event. Patients with complications required more days on mechanical ventilation and a longer length of stay and had a higher mortality. Circulatory support and renal failure were associated with a higher mortality. Sociedad Argentina de Pediatría

Polyetheretherketone (PEEK) Rods in Lumbar Spine Degenerative Disease: A Case Series.

Retrospective case series. The purpose of our study was to retrospectively review the results of posterior lumbar fusion using polyetheretherketone (PEEK) rods. Pedicle screw and rod instrumentation has become the preferred technique for performing stabilization and fusion in the lumbar spine for degenerative disease. Rigid fixation with titanium rods leads to high fusion rates, but may also contribute to stress shielding and adjacent segment degeneration (ASD). Thus, some have advocated using semirigid rods made of PEEK. Although the biomechanical properties of PEEK rods have shown improved stress-shielding characteristics and anterior load-sharing properties, there are very few clinical studies evaluating their application in the lumbar spine. We evaluated a retrospective cohort of 42 patients who underwent posterior lumbar fusion from 2007 to 2009 for the treatment of lumbar spine degenerative disease using PEEK rods. Reoperation rate was the primary outcome evaluated. Fusion rate was also evaluated. Eight of the 42 patients with PEEK rods required reoperation. Reasons for reoperation mainly included ASD (5/8) and nonunion with cage migration (3/8). Radiographically, documented fusion rate was 86%. Mean follow-up was 31.4 months. No statistical differences were found in fusion rates or reoperation between age above 55 years and younger than 55 years (P=1.00), male and female (P=0.110), single or multilevel fusion (P=0.67), and fusion with and without an interbody graft (P=0.69). Smokers showed a trend towards increased risk of reoperation for ASD or instrumentation failure (P=0.056). PEEK rods demonstrate a similar fusion and reoperation rate in comparison to other instrumentation modalities in the treatment of degenerative lumbar spine disease.

Williams syndrome is an uncommon genetic disorder associated with supravalvular aortic stenosis (SVAS) in childhood. We reviewed outcomes of children with Williams syndrome who underwent repair of SVAS during a 30-year period at a single institution. Between 1982 and 2012, 28 patients with Williams syndrome were operated on for SVAS. Mean age at operation was 5.2 years (range, 3 months to 13 years), and mean weight at operation was 18.6 kg (range, 4.1 to 72.4 kg). Associated cardiac lesions in 11 patients (39.3%) were repaired at the time of the SVAS repair. The most common associated cardiac lesion was main pulmonary artery stenosis (8 of 28 [28%]). A 3-patch repair was performed in 10 patients, a Doty repair in 17, and a McGoon repair in 1 (3.6%). There were no early deaths. Follow-up was 96% complete (27 of 28). Overall mean follow-up was 11.2 years (range, 1 month to 27.3 years). Mean follow-up was 5 years (range, 1 month to 14.3 years) for the 3-patch repair patients and 14.7 years (range, 6 weeks to 27 years) for the Doty repair patients. Of the 17 Doty patients, there were 4 (24%) late deaths, occurring at 6 weeks, 3.5 years, 4 years, and 16 years after the initial operation. There were no late deaths in the 3-patch repair patients. Overall survival was 86% at 5, 10, and 15 years after repair. Survival was 82% at 5, 10 and 15 years for the Doty repair patients. Overall, 6 of 27 patients (22%) patients required late reoperation at a mean of 11.2 years (range, 3.6 to 23 years). No 3-patch repair patients required reoperation. Overall freedom from reoperation was 91% at 5 years and 73% at 10 and 15 years. Freedom from reoperation for the Doty repair patients was 93% at 5 years and 71% at 10 and 15 years. Surgical repair of SVAS in children Williams syndrome has excellent early results. However, significant late mortality and morbidity warrants close follow-up.

To measure the proportion of women with transvaginal prolapse mesh complications and their association with surgeon volume. We conducted a retrospective, population-based cohort study of all women who underwent a mesh-based prolapse procedure using administrative data (hospital procedure and physician billing records) between 2002 and 2013 in Ontario, Canada. The primary outcome was surgical revision of the mesh. Primary exposure was surgeon volume: high (greater than the 75th percentile, requiring a median of five [interquartile range 5-6] procedures per year) and very high (greater than the 90th percentile, requiring a median of 13 [interquartile range 11-14] procedures per year) volume mesh implanters were identified each year. Primary analysis was an adjusted Cox proportional hazards model. A total of 5,488 women underwent mesh implantation by 1 of 368 unique surgeons. Median follow-up time was 5.4 (interquartile range 3.0-8.0) years. We found that 218 women (4.0%) underwent mesh reoperation a median of 1.17 (interquartile range 0.58-2.90) years after implantation. The hazard of reoperation for complications was only lower for patients of very high-volume surgeons (3.0% [145/3,001] compared with 4.8% [73/2,447], adjusted hazards ratio 0.59, 95% confidence interval 0.40-0.86). In multivariable modeling, younger age, concomitant hysterectomy, blood transfusion, and increased medical comorbidity were all associated with vaginal mesh reoperation. Approximately 5% of women who underwent mesh-based prolapse surgery required reoperation for a mesh complication within 10 years. The risk of reoperation was lowest for surgeons performing 14 or more procedures per year.

Hypersensitivity to stainless steel sternal sutures are an uncommon occurrence. We present a case of such a patient who developed chronic tissue overgranulation over a sternotomy wound eight weeks post-operatively. Primary suspicion was infection, a more common complication however radiological and laboratory investigation showed otherwise. Conservative management provided limited ephemeral success. After ensuring adequate sternal bone healing, the sutures and granulation tissue were eventually surgically removed without complication and the reoperated wound healed well.

Although mid-urethral slings (MUS), have been extensively used for the treatment of female stress urinary incontinence (SUI), no published data exists for the efficiency and the complications of these methods in large patient series. This is a retrospective analysis on patients who underwent MUS surgery since 1999. 531 patients were studied and the results of preoperative assessment, perioperative, early postoperatively and each follow up were registered. Patients were classified in three groups according to the MUS used. Efficacy of each method was evaluated in terms of early postoperative course, late complications and patient's symptoms improvement based questioners, pad test, uroflowmetry, filling cystometry and ultrasonography. Evaluation took place at 7th and 30th postoperative day, 3rd and 12th month and then annually. Each patient was characterized as cured, improved or failed. Trans Obturator (TO) group prevailed in efficiency with no significant differences between trans obturator route with inside-out (TVT-O) and outside-in (TOT). Success rate at 30th month evaluation, was higher in the TO group than in Tension-free Vaginal Tape (TVT) or Single-Incision Mini Slings (SIMS) group (93.4% vs 89.5%, 93.4% vs. 91.7%). None TVT patient required reoperation for remaining/reoccurring SUI, while 1.04% of TO group and 5.48% of SIMS group did. Patients of TVT group underwent reoperation for tape related complications in 2.25%, while 2.07% of TO group and none of SIMS group did. The potential limitation of the study is its retrospective character. Even though TO tapes and SIMS seem more efficient than TVT, they carry a risk of SUI re-occurrence that must be weighted towards the risk of potential complications after TVT.

Resective epilepsy surgery has been shown to have up to 70-80% success rates in patients with intractable seizure disorder. Around 20-30% of patients with Engel Classification III and IV will require reevaluation for further surgery. Common reasons for first surgery failures include incomplete resection of seizure focus, incorrect identification of seizure focus and recurrence of tumor. Clinical chart review of seventeen patients from a single adult comprehensive epilepsy program who underwent reoperation from 2007 to 2014 was performed. High resolution Brain MRI, FDG-PET, Neuropsychometric testing were completed in all cases in both the original surgery and the second procedure. Postoperative outcomes were confirmed by prospective telephone follow up and verified by review of the patient's electronic medical records. Outcomes were classified according to the modified Engel classification system: Engel classes I and II are considered good outcomes. A total of seventeen patients (involving 10 females) were included in the study. The average age of patients at second surgery was 42 (range 23-64 years). Reasons for reoperation included: incomplete first resection (n=13) and recurrence of tumor (n=4). Median time between the first and second surgery was 60 months. After the second surgery, ten of the seventeen patients (58.8%) achieved seizure freedom (Engel Class I), in agreement with other published reports. Of the ten patients who were Engel Class I, seven required extension of the previous resection margins, while three had surgery for recurrence of previously partially resected tumor. We conclude that since the risk of complications from reoperation is low and the outcome, for some, is excellent, consideration of repeat surgery is justified. Copyright © 2017 Elsevier B.V.

Conclusions: In contrast to children and adults with TOF/APV, infants carry significant early mortality. But the mid-term outcome for patients who survive the initial repair of TOF/APV is acceptable. However, these patients require constant surveillance and irrespective of the methods of RVOT management, the reoperation rates are expected to be high as more of these patients survive into adulthood.

Low anastomotic leak rate after colorectal surgery: a single-centre study.

Jones, O M; John, S K P; Horseman, N; Lawrance, R J; Fozard, J B J

2007-10-01

Anastomotic leak after colorectal surgery is a serious event associated with significant morbidity and mortality. There is little consensus regarding 'acceptable' rates of leakage, however. This study describes the experience of anastomotic leakage after both elective and emergency colorectal surgery in a district general hospital. A prospectively collected database of all patients with a diagnosis of colorectal cancer in a single hospital formed the basis of the study. Leak was defined as breakdown of the anastomosis contributing to death or requiring reoperation or reintervention. A total of 949 patients underwent surgery with an anastomosis between 1996 and 2004, including 331 patients treated with anterior resection. Anastomotic leaks requiring reoperation occurred in eight patients (0.8%). Thirty-day and in-hospital mortality was 4%. A very low rate of anastomotic leakage after colorectal surgery is possible in a district general hospital setting. Given the impact of anastomotic leakage on function, tumour recurrence and long-term survival, it should be considered as a marker of surgical quality when evaluating surgical performance.

Factors determining the recurrence of chronic subdural hematomas (CSDHs) are not clear. Whether opening the so-called internal hematoma membrane is useful has not been investigated. To investigate whether splitting the inner hematoma membrane influences the recurrence rate in patients undergoing burr-hole craniotomy for CSDH. Fifty-two awake patients undergoing surgery for 57 CSDHs were prospectively randomized to either partial opening of the inner hematoma membrane (group A) or not (group B) after enlarged burr-hole craniotomy and hematoma evacuation. Drainage was left in situ for several days postoperatively. Groups were comparable with regard to demographic, clinical, and imaging variables. Outcome was assessed after 3-6 weeks for the combined outcome variable of reoperation or residual hematoma of one third or more of the original hematoma thickness. Fourteen patients underwent reoperation for clinical deterioration or residual hematoma during follow-up (n = 6 in group A, 21%; n = 8 in group B, 28 %) (P = 0.537). Residual hematoma of ≥ one third not requiring surgery was present in 7 patients in group A (25%) and 10 patients in group B (36%) (P = 0.383). The overall cumulative failure rate (reoperation or hematoma thickness ≥ one third) was 13/28 (46%) in group A and 18/28 in group B (P = 0.178; relative risk, 0.722 [95% confidence interval, 0.445-1.172]; absolute risk reduction -16% [95% confidence interval, -38% to 8%]). Opening the internal hematoma membrane does not alter the rate of patients requiring revision surgery and the number of patients showing a marked residual hematoma 6 weeks after evacuation of a CSDH.

Stewart, Andrew D; Abdelbary, Hesham; Beaulé, Paul E

2017-09-01

Greater trochanteric fracture/nonunion can be a devastating complication with significant functional impact after total hip arthroplasty, and their fixation remains a challenge because of the significant forces being transmitted as well as the poor bone quality often associated with these fractures. The objective of this study is to investigate the rates of reoperation and trochanteric nonunion using a third-generation cable-plate system at one center. Thirty-five patients, mean age 72.9 years (range 46-98 years) with 24 women and 11 men, underwent fixation of their fractured greater trochanter using a third-generation cable-plate system. The indications were: periprosthetic fracture (n = 17), complex primary arthroplasty (n = 5), and complex revision arthroplasty (n = 13). Primary outcomes included rates of reoperation and radiographic union. At a mean follow-up of 2.5 years, trochanteric union rate was 62.9% with nonunion rate of 31.4%, and fibrous union in 5.7%. In regard to quality of initial apposition, only 40% achieved a perfect bone on bone reduction. Ten patients (28.6%) had evidence of wire breakage. Five patients (14.3%) required reoperation and removal of the internal fixation because of lateral hip pain. Fixation of the trochanteric fractures remains a challenge with a relatively high reoperation rate. Poor bone quality and capacity to maintain a stable reduction continue to make this complication after total hip arthroplasty a difficult problem to solve. Copyright © 2017.

Rheumatoid patients may develop a retrodental lesion (atlantoaxial rheumatoid pannus) that may cause cervical instability and/or neurological compromise. The objective is to characterize clinical and radiographic outcomes after posterior instrumented fusion for atlantoaxial rheumatoid pannus. We retrospectively reviewed all patients who underwent posterior fusions for an atlantoaxial rheumatoid pannus at a single institution. Both preoperative and postoperative imaging was available for all patients. Anterior or circumferential operations, non-atlantoaxial panni, or prior C1-C2 operations were excluded. Primary outcome measures included Nurick score, Ranawat score (neurologic status in patients with rheumatoid arthritis), pannus regression, and reoperation. Pannus volume was determined with axial and sagittal views on both preoperative and postoperative radiological images. Thirty patients surgically managed for an atlantoaxial rheumatoid pannus were followed for a mean of 24.43 months. Nine patients underwent posterior instrumented fusion alone, while 21 patients underwent posterior decompression and instrumented fusion. Following a posterior instrumented fusion in all 30 patients, the pannus statistically significantly regressed by 44.44%, from a mean volume of 1.26cm(3) to 0.70cm(3) (ppannus radiographically regressed by 44.44% over a mean of 8.02 months, and patients clinically improved per the Nurick score. The Ranawat score did not improve, and 20% of patients required reoperation over a mean of 13.18 months. The annualized reoperation rate was approximately 13.62%. Copyright © 2015 Elsevier B.V.

The use of surgical drains in patients undergoing thyroid surgery is standard surgical teaching. Life-threatening complications, arising from post-operative haematomas, mandates their utilization. There is increasing evidence to suggest that this is an outdated practice. This paper determines whether thyroid surgery can be safely performed without the routine use of drains. A retrospective review of patients undergoing thyroid surgery, over a three year period was performed and post-operative complications documented. One hundred and four thyroidectomies were performed. 63 (60.6%) patients had a partial thyroidectomy, 27 (25.9%) had a total thyroidectomy and 14 (13.5%) had a sub-total thyroidectomy. Suction drains were not inserted in any patient. A cervical haematoma did not develop in any patient in this series and no patient required re-operation. There is no evidence to suggest the routine use of surgical drains following uncomplicated thyroid surgery reduces the rate of haematoma formation or re-operation rates and indeed is now unwarranted.

The aortic valve-sparing David procedure has been applied to the elective treatment of patients with aortic aneurysms with excellent results. The use of this technique in patients with acute aortic dissection type A (AADA) is still a matter of debate. We present our long-term experience with 109 patients with AADA who had the valve-sparing David I procedure. Between July 1993 and October 2015, 109 patients with AADA had the valve-sparing David I procedure at our centre. We conducted a retrospective review with follow-up. The mean age was 54 ± 12 years; 78 (72%) patients were men. Marfan syndrome was present in 6 (5%) patients and bicuspid aortic valve in 3 (3%). Only 4 (4%) patients received the isolated David procedure; 50 (46%) underwent additional proximal, 13 (12%) subtotal and 42 (39%) total aortic arch replacement. The in-hospital mortality rate was 11% ( n  = 12). Intraoperative/discharge echocardiography showed aortic insufficiency ≤ I° in 93 of 97 patients (96%). Mean follow-up time was 8.3 ± 5.7 years. The survival rate after discharge at 1, 5 and 10 years was 94%, 90% and 78%, respectively. Thirteen percent ( n  = 13) of patients underwent valve-related reoperation. Freedom from valve-related reoperation at 1, 5 and 10 years was 96%, 88% and 85%, respectively. Compared to patients who underwent the David I procedure for any reason other than AADA, there were no significant differences in long-term survival rates ( P  = 0.29) and freedom from a valve-related reoperation ( P  = 0.39). The valve-sparing David I procedure has acceptable long-term results even in emergent operations for AADA and is not inferior when performed in elective settings. © The Author 2017.

Full Text Available Infective endocarditis (IE is an infection of the endocardium that involves valves and adjacent mural endocardium or a septal defect. Local complications include severe valvular insufficiency, which may lead to intractable congestive heart failure and myocardial abscesses. If left untreated, IE is generally fatal. Diagnosing IE can be straightforward in patients with the typical oslerian manifestations such as bacteremia, evidence of active valvulitis, peripheral emboli, and immunologic vascular phenomena. In the acute course, however, the classic peripheral stigmata may be few or absent, particularly among intravenous drug abuse (IVDA patients in whom IE is often due to a S. aureus infection of right-sided heart valves. We present a complicated case of a very aggressive native aortic valve MSSA (methicillin sensitive Staphylococcus aureus IE in a young adult male with a past medical history of bicuspid aortic valve and IV drug abuse. His clinical course was complicated by aortic valve destruction and development of third-degree AV block, as well as an aorto-left atrial fistula requiring emergent operation for AV replacement and patch repair. The patient required two reoperations for recurrent endocarditis and its complications.

A patient accounting system is a subsystem of a hospital information system. This system like other information systems should be carefully designed to be able to meet users' requirements. The main aim of this research was to investigate users' requirements and to determine whether current patient accounting systems meet users' needs or not. This was a survey study, and the participants were the users of six patient accounting systems used in 24 teaching hospitals. A stratified sampling method was used to select the participants (n = 216). The research instruments were a questionnaire and a checklist. The mean value of ≥3 showed the importance of each data element and the capability of the system. Generally, the findings showed that the current patient accounting systems had some weaknesses and were able to meet between 70% and 80% of users' requirements. The current patient accounting systems need to be improved to be able to meet users' requirements. This approach can also help to provide hospitals with more usable and reliable financial information.

Despite the controversy, the aortic homograft is supposedly the best option in acute infective endocarditis (AIE), due to its resistance to reinfection. However, the technical complexity and the risk of structural deterioration over time have limited its utilization. The aim of this study was to evaluate the long-term results of aortic homograft for the treatment of infective endocarditis in our institution with particular attention to predictors of survival and homograft reoperation. The cohort includes 112 patients who underwent aortic valve replacement with an aortic homograft for AIE between January 1990 and December 2014. Fifteen patients (13.4%) died during the first 30 days after the operation. Two patients were lost to follow-up after discharge from the hospital; therefore, 95 patients were available for long-term analysis. The median duration of follow-up was 7.8 years (IQR 4.7-17.6). Five patients (5.3%) suffered a recurrence of infective endocarditis (1 relapse and 4 new episodes). Sixteen patients (16.8%) were reoperated for structural valve degeneration (SVD; n = 14, 87.5%) or for infection recurrence (n = 2, 12.5%). Freedom from homograft reoperation for infective endocarditis or structural homograft degeneration at 10 and 15 years postoperatively was 86.3 ± 5.5 and 47.3 ± 11.0%, respectively. For patients requiring homograft reoperation, the median interval to reintervention was 11.6 years (IQR 8.3-14.5). Long-term survival was 63.6% (95% CI 52.4-72.8%) and 53.8% (95% CI 40.6-65.3%) at 10 and 15 years, respectively. The use of aortic homograft in acute aortic valve endocarditis is associated with a remarkably low risk of relapsing infection and very acceptable long-term survival. The risk of reoperation due to SVD is significant after one decade especially in young patients. The aortic homograft seems to be ideally suited for reconstruction of the aortic valve and cardiac structures damaged by the infective process especially in early surgery. �

Aortic root replacement after a previous operation on the aortic valve, aortic root, or ascending aorta remains a major challenge. Records of 56 consecutive patients (44 men; mean age, 56.4 +/- 13.6 years) undergoing reoperative aortic root replacement between June 1994 and June 2005 were reviewed retrospectively. Reoperation was performed 9.4 +/- 6.7 years after the last cardiac operation. Indications for reoperation were true aneurysm (n = 14 [25%]), false aneurysm (n = 10 [18%]), dissection or redissection (n = 9 [16%]), structural or nonstructural valve dysfunction (n = 10 [18%]), prosthetic valve-graft infection (n = 12 [21%]), and miscellaneous (n = 1 [2%]). Procedures performed were aortic root replacement (n = 47 [84%]), aortic root replacement plus mitral valve procedure (n = 5 [9%]), and aortic root replacement plus arch replacement (n = 4 [7%]). In 14 (25%) patients coronary artery bypass grafting had to be performed unexpectedly during the same procedure or immediately after the procedure to re-establish coronary perfusion. Hospital mortality reached 17.9% (n = 10). Multivariate logistic regression analysis revealed the need for unplanned perioperative coronary artery bypass grafting as the sole independent risk factor for hospital death (P = .005). Actuarial survival was 83.8% +/- 4.9% at 1 month, 73.0% +/- 6.3% at 1 year, and 65.7% +/- 9.0% at 5 years after the operation. One patient had recurrence of endocarditis 6.7 months after the operation and required repeated homograft aortic root replacement. Reoperative aortic root replacement remains associated with a high postoperative mortality. The need to perform unplanned coronary artery bypass grafting during reoperative aortic root replacement is a major risk factor for hospital death. The optimal technique for coronary reconstruction in this setting remains to be debated.

There is preliminary evidence to suggest that some published warfarin dosing algorithms produce biased maintenance dose predictions in patients who require higher than average doses. We conducted a meta-analysis of warfarin dosing algorithms to determine if there exists a systematic under- or overprediction of dose requirements for patients requiring ≥7 mg/day across published algorithms. Medline and Embase databases were searched up to September 2015. We quantified the proportion of over- and underpredicted doses in patients whose observed maintenance dose was ≥7 mg/day. The meta-analysis included 47 evaluations of 22 different warfarin dosing algorithms from 16 studies. The meta-analysis included data from 1,492 patients who required warfarin doses of ≥7 mg/day. All 22 algorithms were found to underpredict warfarin dosing requirements in patients who required ≥7 mg/day by an average of 2.3 mg/day with a pooled estimate of underpredicted doses of 92.3% (95% confidence interval 90.3-94.1, I 2 = 24%). © 2017 American Society for Clinical Pharmacology and Therapeutics.

The purpose of this study is to understand preliminary education. Level of understanding and the degrees of educational requirement for cancer patients on radiotherapy and to present the preliminary data to development of effective and practical patients treatment programs. Based on the above mentioned results of this study. Relationship between degrees of knowledge and demand for educational requirement for patients who are undertaking radiotherapy could be varied with different factors such as educational background, ages, regions of treatment, experience of symptoms. In general, patients do not have enough information, on the other hand, have very high demand for educational requirement. Customized education patients by patients would not be possible in reality. However, if we could provide standard for patients and establish systematic sessions during treatment based on this study, more and better patients satisfaction and results of treatments could be achieved.

Refractory bleeding after complex cardiovascular surgery often leads to increased length of stay, cost, morbidity, and mortality. Recombinant activated factor VII administered in the intensive care unit can reduce bleeding, transfusion, and surgical re-exploration. We retrospectively compared factor VII administration in the intensive care unit with reoperation for refractory bleeding after complex cardiovascular surgery. From 1501 patients who underwent cardiovascular procedures between December 2003 and September 2007, 415 high-risk patients were identified. From this cohort, 24 patients were divided into 2 groups based on whether they either received factor VII in the intensive care unit (n = 12) or underwent reoperation (n = 12) for refractory bleeding. Preoperative and postoperative data were collected to compare efficacy, safety, and economic outcomes. In-hospital survival for both groups was 100%. Factor VII was comparable with reoperation in achieving hemostasis, with both groups demonstrating decreases in chest tube output and need for blood products. Freedom from reoperation was achieved in 75% of patients receiving factor VII, whereas reoperation was effective in achieving hemostasis alone in 83.3% of patients. Prothrombin time, international normalized ratio, and median operating room time were significantly less (P factor VII. Both groups had no statistically significant differences in other efficacy, safety, or economic outcomes. Factor VII administration in the intensive care unit appears comparable with reoperation for refractory bleeding after complex cardiovascular surgical procedures and might represent an alternative to reoperation in selected patients. Future prospective, randomized controlled trials might further define its role. Copyright © 2011 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

The morbidity of anastomotic dehiscence may be mitigated by a defunctioning stoma, but it is unclear if it is required for most low rectal anastomoses. Preoperative risk factors leading to anastomotic complications and the indications for faecal diversion have yet to be clearly defined. Using the American College of Surgeons-National Surgical Quality Improvement Project (ACS-NSQIP) participant-use file, patients were identified who underwent low anterior resection with anastomosis for cancer at the 211 participating hospitals in 2005-08. A total of 1791 patients underwent low anterior resection. Patients were subdivided into two groups based on the level of the anastomosis. Of these 1266 patients had a low pelvic anastomosis (LPA) and 525 a coloanal anastomosis (CAA). In the LPA group, 606 patients had a stoma and 660 had no stoma. There were no differences in wound complications, sepsis or septic shock. Patients who had a stoma were more likely to have postoperative acute renal failure (1.7 vs 0.5%, P = 0.0485, OR 3.674). In the CAA group, 352 had a stoma and 173 had no stoma. In patients without faecal diversion, there was a significantly greater incidence of sepsis (8.7 vs 3.7%, P = 0.022, OR 2.47), septic shock (3.5 vs 0.57%, P = 0.018, OR 6.29) and need for reoperation (11 vs 1.7%, P = 0.0001, OR 7.11). Hospital length of stay was significantly longer with CAA and no stoma. On multivariate analysis, not having a stoma with a CAA was a risk factor for serious postoperative morbidity. While a defunctioning stoma with a coloanal anastomosis seems to protect from postoperative sepsis, septic shock and need for reoperation, it is likely that it is overused in rectal cancer surgery.

Editorial Commentary: Graft Removal Versus Retention for Septic Arthritis After Anterior Cruciate Ligament Reconstruction: Accounting for Patient Preference Flips the Script on Current Practice.

Science.gov (United States)

Cote, Mark P

2018-03-01

Septic arthritis is a rare but potentially devastating complication after anterior cruciate ligament (ACL) reconstruction. Studies examining surgical treatment options including graft retention and removal are largely inconclusive. Although the literature indicated that 43.8% of patients who have the graft removed later go on to have a revision ACL reconstruction compared with only 6.5% among those whose graft is retained, this expected-value decision analysis found removal to be the optimal treatment for patients with septic arthritis after ACL reconstruction. This is largely based on patient preference to avoid a late reoperation for residual knee infection. These findings support the concept of utility when considering treatment options for patients with a septic knee. For some, avoiding a late reoperation for a persistent infection is the most important factor and as such graft removal may be the most appropriate treatment to produce a positive outcome among these patients despite the fact that currently, an attempt at graft retention could represent the generally preferred treatment option among practicing surgeons.

Healing of complete, atypical femoral fractures is thought to be impaired, but the evidence is weak and appears to be based on the delayed healing observed in patients with incomplete atypical fractures. Time until fracture healing is difficult to assess, therefore we compared the reoperation rates between women with complete atypical femoral fractures and common femoral shaft fractures. We searched the orthopaedic surgical registry in Östergötland County for patients with subtrochanteric and femoral shaft fractures (ICD-10 diagnosis codes S72.2, S72.3 and M84.3F) between January 1st 2007 and December 31st 2013. Out of 895 patients with surgically treated femoral shaft fractures, 511 were women 50 years of age or older. Among these we identified 24 women with atypical femoral shaft fractures, and 71 with common shaft fractures. Reoperations were performed in 6 and 5 patients, respectively, odds ratio 4.4 (95% CI 1.2 to 16.1). However, 5 reoperations in the atypical fracture group could not be ascribed to poor healing. In 3 patients the reoperation was due to a new fracture proximal to a standard intramedullary nail. In 2 patients the distal locking screws were removed due to callus formation that was deemed incomplete 5 months post-operatively. The one patient with poor healing showed faint callus formation at 5 months when the fracture was dynamised and callus remained sparse at 11 months. Among patients with common shaft fractures, 2 reoperations were performed to remove loose screws, 2 because of peri-implant fractures and 1 reoperation due to infection. Reoperation rates in patients with complete atypical femoral fractures are higher than in patients with common shaft fractures. The main reason for failure was peri-implant fragility fractures which might be prevented with the use of cephalomedullary nails at the index surgery. Fracture healing however, seems generally good. A watchful waiting approach is advocated in patients with fractures that appear to

Thyroid disease and hyperparathyroidism are the most common endocrine disorders. The incidence of thyroid disease in patients with hyperparathyroidism ranges in the different series from 17 to 84%, and thyroid cancer occurs with an incidence ranging from 2 to 15%. The aim of our study was to analyze the management of elderly patients with concomitant thyroid and parathyroid disease in order to define the best surgical therapeutic strategy and avoid reoperations associated with a higher risk of complications. All consecutive patients (64 patients, age range 60-75 years), undergoing surgery for hyperparathyroidism, from January 2011 to June 2014, were retrospectively evaluated. Enrolled patients were divided into two study groups of patients affected by hyperparathyroidism with or without a concomitant thyroid disease. Out of 64 patients enrolled in our study (24 men, age range 60-75 years), affected by hyperparathyroidism, 34 had an associated thyroid disease and were treated with total thyroidectomy and parathyroidectomy. The group, who underwent parathyroidectomy associated with thyroidectomy, had no greater complications than the group receiving only parathyroidectomy. Thyroid disease must be excluded in patients affected by hyperparathyroidism. It is difficult to determine whether hyperparathyroidism can be considered a risk factor for thyroid disease, but an accurate preoperative study is essential for a surgery able to treat both thyroid and parathyroid disease. In this way, we avoid the elderly patient, with associated morbidity and increased surgical risk, to undergo a reoperation for thyroid disease, burdened with major complications.

The radiologic evaluation of Hirschsprung disease is well described in the literature. However, there is a paucity of literature describing the appearance of the neo-rectum and colon after repair, specifically describing findings in patients with poor functional outcome, which would suggest the need for reoperation. We describe findings on contrast enema and correlate them with surgical findings at reoperation in children with poor functional outcome after primary repair for Hirschsprung disease who suffer from bowel dysfunction that can manifest with either soiling or obstructive symptoms such as enterocolitis. Children were identified from our colorectal surgery database. At the time of abstract submission, 35 children had contrast enemas prior to reoperation. Additional children continue to present for evaluation. The majority of children included in the study had their primary repair performed elsewhere. The initial procedures included: Duhamel (n = 11), Soave (n = 20) or Swenson (n = 3). One child had undergone a primary Soave repair and subsequently had a Swenson-type reoperation but continued to have a poor outcome. One child's initial surgical repair could not be determined. Images were reviewed by a staff pediatric radiologist and a pediatric radiology fellow. Findings encountered on contrast enema in these children include a distal narrowed segment due to stricture or aganglionic/transitional zone segment (8), dilated/hypomotile distal segment (7), thickened presacral space due to compressing Soave cuff (11), dilated Duhamel pouch (8), active enterocolitis (3) and partially obstructing twist of the pull-through segment (1). Multiple anatomical and pathological complications exist that can lead to bowel dysfunction in children after repair of Hirschsprung disease. Little recent literature exists regarding the radiographic findings in children. We had the opportunity to review a substantial series of these children, describe the contrast enema

Purpose: To examine factors associated with one step surgery in case of non-palpable breast cancer. Materials and methods: Clinical data of 152 consecutively diagnosed patients with breast cancer were analyzed retrospectively. Preoperative diagnostic findings were divided in subgroups: mammographically visible mass/microcalcifications/sonographically visible mass/sonographically visible architectural distortion. Correlation between tumor-size, radiologic tumor morphology, quality of localization and number of operation was evulated. For localization exact wire position was defined less than 3 mm apart from the lesion. Results: One hundred and thirty-six patients attempted breast conservation and underwent preoperative tumor localization. Fourteen of 16 patients had mastectomy without preoperative localization. Average tumor size was 12 mm for one-operation, and 17 mm for re-operation. Significant correlation (p < 0.001) was found between one operation and masses visible in mammograms (55/62 (89%) patients) or sonography (53/64 (83%) patients). Significant correlation was found (p < 0.001) between more re-operation and microcalcifications in mammograms (33/89 (37% patients). In 123/138 (89%) cases wire position was central, in 15/138 (11%) cases distance was maximally 10 mm. No significant correlation was found between number of operation and wire position. Re-operation was required in 38 cases. Conclusion: Mammographically or sonographically visible mass, small size of tumors, preoperative percutaneous biopsy and exact preoperative localization are important for a single step procedure for definite surgical treatment, that we found in 74% of the patients

Chest wall masculinization by means of mastectomy is an important gender affirming surgery for transmasculine and non-binary patients. Limited data exist comparing commonly used techniques in masculinizing top surgery, and most are single institution studies. A systematic review was performed on primary literature dedicated specifically to the technical aspects and outcomes of mastectomy for masculinizing top surgery. For each study, patient demographics and surgical outcomes were compared. Eight studies met inclusion criteria. There were 2138 breasts with an average patient age of 28.6 years and the average breast weight was 353 g. The most commonly reported techniques are those without skin resection (8.0%), those with periareolar skin resection (34.1%), inferior pedicle mammoplasty (15.7%), and inframammary fold skin excision with free nipple grafting (FNG, 42.2%). In total, 6.0% of all breasts required acute reoperation for hematoma and 26.5% required secondary operations. Acute reoperation occurred significantly less often in the FNG cohort (4.8%) compared with both the inferior pedicle mammaplasty cohort (8.9%, P < 0.05) and techniques without skin resection cohort (10.3%, P < 0.05). Secondary operations occurred significantly more often in the periareolar skin resection cohort (37.5%) than techniques without skin resection cohort (19.0%, P < 0.01), inferior pedicle mammaplasty cohort (27.9%, P < 0.01), and FNG cohort (20.3%, P < 0.05). In addition, secondary operations occurred significantly more often in inferior pedicle mammaplasty cohort (27.9%) compared with FNG cohort (20.3%, P < 0.01). This analysis notes several significant differences with regard to percentage requiring acute reoperation and percentage requiring secondary revision based on technique. Candidates for masculinizing top surgery should be educated on these differences.

Effect of preoperatively continued aspirin use on early and mid-term outcomes in off-pump coronary bypass surgery: a propensity score-matched study of 1418 patients.

Full Text Available To date, effect of preoperatively continued aspirin administration in off-pump coronary artery bypass grafting (CABG is less known. We aimed to assess the effect of preoperatively continued aspirin use on early and mid-term outcomes in patients receiving off-pump CABG.From October 2009 to September 2013 at the Fuwai Hospital, 709 preoperative aspirin users were matched with unique 709 nonaspirin users using propensity score matching to obtain risk-adjusted outcome comparisons between the two groups. Early outcomes were in-hospital death, stroke, intra- and post-operative blood loss, reoperation for bleeding and blood product transfusion.

The purpose of this study was to determine failure rates, functional outcomes, and risk factors for failure after revision anterior shoulder stabilization surgery in high-risk adolescent athletes. Adolescent athletes who underwent primary anterior shoulder stabilization were reviewed. Patients undergoing subsequent revision stabilization surgery were identified and analyzed. Failure rates after revision surgery were assessed by Kaplan-Meier analysis. Failure was defined as recurrent instability requiring reoperation. Functional outcomes included the Marx activity score; American Shoulder and Elbow Surgeons score; and University of California, Los Angeles score. The characteristics of patients who required reoperation for recurrent instability after revision surgery were compared with those of patients who required only a single revision to identify potential risk factors for failure. Of 90 patients who underwent primary anterior stabilization surgery, 15 (17%) had failure and underwent revision surgery (mean age, 16.6 years; age range, 14 to 18 years). The mean follow-up period was 5.5 years (range, 2 to 12 years). Of the 15 revision patients, 5 (33%) had recurrent dislocations and required repeat revision stabilization surgery at a mean of 50 months (range, 22 to 102 months) after initial revision. No risk factors for failure were identified. The Kaplan-Meier reoperation-free estimates were 86% (95% confidence interval, 67% to 100%) at 24 months and 78% (95% confidence interval, 56% to 100%) at 48 months after revision surgery. The mean final Marx activity score was 14.8 (range, 5 to 20); American Shoulder and Elbow Surgeons score, 82.1 (range, 33 to 100); and University of California, Los Angeles score, 30.8 (range, 16 to 35). At 5.5 years' follow-up, adolescent athletes had a high failure rate of revision stabilization surgery and modest functional outcomes. We were unable to convincingly identify specific risk factors for failure of revision surgery. Level IV

Recurrent Volvulus of an Ileal Pouch Requiring Repeat Pouchopexy: A Lesson Learnt

Full Text Available Introduction. Restorative surgery for ulcerative colitis with ileal pouch anal anastomosis (IPAA is frequently accompanied by complications. Volvulus of the ileal pouch is one of the most rarely reported late complications and to our knowledge no report exists on reoperative surgery for this condition. Case Report. A 58-year-old woman who previously had undergone restorative proctocolectomy due to ulcerative colitis with an IPAA presented with volvulus of the pouch. She was operated with a single row pouchopexy to the presacral fascia. Two months later she returned with a recurrent volvulus. At reoperation, the pouch was found to have become completely detached from the fascia. A new pexy was made by firmly anchoring the pouch with two rows of sutures to the presacral fascia as well as with sutures to the lateral pelvic walls. At follow-up after five months she was free of symptoms. Conclusion. This first report ever on reoperative surgery for volvulus of a pelvic pouch indicates that a single row pouchopexy might be insufficient for preventing retwisting. Several rows seem to be needed.

Full Text Available OBJECTIVE - To analyze the immediate and late results of mitral valve repair with quadrangular resection of the posterior leaflet without the use of a prosthetic ring annuloplasty. METHODS - Using this technique, 118 patients with mitral valve prolapse who underwent mitral repair from January '84 through December '96 were studied. Age ranged from 30 to 86 (mean = 59.1±11.8 years and 62.7% were males. An associated surgery was performed in 22% of the patients, and coronary artery bypass graft was the most frequently performed surgery (15 patients - 12.7%. In 20 (16.9% patients other associated techniques of mitral valve repair were used and shortening of elongated chordae tendineae was the most frequent one (6 patients. RESULTS - Immediate mortality was 0.9% (one patient. Long-term rates for thromboembolism, endocarditis, re-operation and death in the late postoperative period were 0.4%, 0.4%, 1.7% and 2.2% patients/year, respectively. The actuarial curve of survival was 83.8±8.6% over 12 years; survival free from re-operation was 91.8±4.3%, free from endocarditis was 99.2±0.8% and free from thromboembolism was 99.2±0.8%. In the late postoperative period, 93.8% of the patients were in functional class 1 (NYHA, with a complete follow-up in 89.7% of the patients. CONCLUSION - Patients with mitral valve prolapse who undergo mitral valve repair using this technique have a satisfactory prognosis over 12 years.

Reoperations of the mitral valve have a higher rate of complications when compared with the first surgery. With the field of video-assisted techniques for the first surgery of mitral valve became routine, reoperation cases began to arouse interest for this less invasive procedures. To assess the results and the technical difficulties in 10 patients undergoing minimally invasive redo mitral valve surgery. Cardiopulmonary bypass was installed through a cannula placed in the femoral vessels and right internal jugular vein, conducted in 28 degrees of temperature in ventricular fibrillation. A right lateral thoracotomy with 5 to 6 cm in the third or fourth intercostal space was done, pericardium was displaced only at the point of atriotomy. The aorta was not clamped. Ten patients with mean age of 56.9 ± 10.5 years, four were in atrial fibrilation rhythm and six in sinusal. Average time between first operation and reoperations was 11 ± 3.43 years. The mean EuroSCORE group was 8.3 ± 1.82. The mean ventricular fibrillation and cardiopulmonary bypass was respectively 70.9 ± 17.66 min and 109.4 ± 25.37 min. The average length of stay was 7.6 ± 1.5 days. There were no deaths in this series. Mitral valve reoperation can be performed through less invasive techniques with good immediate results, low morbidity and mortality. However, this type of surgery requires a longer duration of cardiopulmonary bypass, especially in cases where the patient already has prosthesis. The presence of a minimal aortic insufficiency also makes this procedure technically more challenging.

Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), although estimates of LPDT range from 0.6 to 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT. This investigation is the largest yet conducted on LPDT, and sought to identify incidence, risk factors for, and complications associated with LPDT. This observational cohort study employed the American College of Surgeons National Surgical Quality Improvement Program dataset (years 2012-2015). Patients who underwent spine surgery were identified based on presence of primary listed Current Procedural Terminology (CPT) codes corresponding to spinal fusion or isolated posterior decompression without fusion. The primary variable in this study was occurrence of LPDT, identified as reoperation or readmission with durotomy-specific CPT or International Classification of Diseases, Ninth Revision, Clinical Modification codes but without durotomy codes present for the index procedure. Descriptive statistics were generated. Bivariate and multivariate analyses were conducted using chi-square tests and multiple logistic regression, respectively, generating both risk factors for LPDT and independent association of LPDT with postoperative complications. Statistical significance was defined as p<.05. In total, 86,212 patients were analyzed. The overall rate of reoperation or readmission without reoperation for LPDT was 2.0 per 1,000 patients (n=174). Of LPDT patients, 97.7% required one or more unplanned reoperations (n=170), and 5.7% of patients (n=10) required two reoperations. On multivariate analysis, lumbar procedures (odds ratio [OR] 2.79, p

Acute dysfunction of mechanical aortic valve prostheses is a life-threatening adverse event. Pannus overgrowth, which is fibroelastic hyperplasia originating from the periannular area, is one cause of dysfunction. The aim of this study was to determine the annual incidence of readmittance resulting from acute obstruction caused by pannus during 30 years of observation in patients with Medtronic-Hall aortic valve prostheses and to analyze the risk factors associated with pannus development. From 1982 to 2004, 1,187 patients in our department underwent aortic valve replacement with Medtronic-Hall mechanical monoleaflet valve prostheses. As of December 31, 2012, 27 of these patients (2.3%) had presented with acute valve dysfunction caused by pannus obstruction. The annual incidence of pannus was 0.7 per 1,000. The median time from the primary operation to prosthetic dysfunction was 11.1 years (range, 1.2 to 26.8 years). Of the 20 patients who underwent reoperation, 2 died. Seven patients died before reoperation. Women had a higher risk for the development of obstructing pannus, and patients with pannus obstruction were younger. Valve size was not an independent risk factor. Women and younger patients are at higher risk for pannus development. When acute dysfunction by pannus is suspected in a mechanical aortic valve, an immediate echocardiogram and an emergency aortic valve replacement should be carried out because of the potential of a fatal outcome.

Low serum albumin levels (hypoalbuminemia) have classically been used to identify malnutrition. The effect of increasing severity of malnutrition on postoperative outcomes in patients undergoing hip fracture surgery has not been well delineated on a large scale. Retrospective. Multicenter. A total of 12,373 patients undergoing hip fracture surgery from 2006 to 2013 National Surgery Quality Improvement Project data were identified. Patient demographic, comorbidity, and preoperative laboratory data and complication, reoperation, and readmission data were collected. Multivariate logistic regression was used to determine the effect of increasing severity of malnutrition on rates of 30-day postoperative complications, readmissions, and reoperations. A total of 12,373 hip fractures met inclusion criteria. A total of 6506 (52.6%) patients had normal albumin levels (albumin ≥3.5 g/dL), 3205 (25.9%) patients were mildly malnourished (albumin 3.1-3.49 g/dL), 2265 (18.3%) were moderately malnourished (albumin 2.4-3.1 g/dL), and 397 (3.2%) patients were severely malnourished (albumin malnutrition was associated with a 2-fold increase in the odds of postoperative complications and mortality when compared with mild malnutrition (P malnutrition was associated with significantly longer lengths of stay and higher odds of experiencing a related readmission (P hip fracture surgery.

We reviewed our experience with aortic valve-sparing operations in Marfan syndrome during last 5 years. Between March 2004 and June 2009, 94 patients with aortic root aneurysms underwent valve-sparing operations. Of these, 37 (68% male) were diagnosed with Marfan syndrome, according to the Ghent diagnostic criteria. Mean age was 30 +/- 10 years (range, 11 to 59 years). Moderate/severe aortic regurgitation was present in 13%, and the mean diameter of the Valsalva sinuses was 50 +/- 4 mm (range, 42 to 62 mm). The David V modification was performed in the last 28 patients. Additional procedures were mitral valve repair in 6, tricuspid valve repair in 3, closure of septal atrial defect in 2, and closure of a patent foramen ovale in 13. Mean follow-up was 27 +/- 16 months (range, 1 to 61 months). There were no in-hospital deaths and no major adverse outcomes. One patient required implantation of a mechanical prosthesis during the same procedure because of moderate aortic regurgitation. One late death occurred. No patients required reoperation. In the last follow-up, 23 patients did not have aortic regurgitation, 12 had grade I, and 1 had grade II. No thromboembolic complications have been documented, and 97% of the patients are free from anticoagulation. Short-term and midterm results with the reimplantation technique for aortic root aneurysms in Marfan patients are excellent. If long-term results are similar, this technique could be the treatment of choice for these patients. 2010 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

This study was undertaken to assess the frequency and outcome of cardiovascular surgery in children with Marfan or Loeys-Dietz syndrome. A retrospective review from 2 regional Marfan subspecialty clinics was performed. Between 1997 and 2007, 204 children with Marfan syndrome and 17 children with Loeys-Dietz syndrome were followed serially. Of these patients, 35 were identified who had undergone cardiovascular surgery at 18 years of age or less. Demographic, echocardiographic, and surgical data were collected. Surgery was performed at a median of 3 years (0-15 years) after diagnosis and a mean age of 11.5 +/- 6.2 years. Aortic root replacement was the initial surgery in 30 patients, and mitral valve surgery was the initial surgery in 8 patients, with 3 patients undergoing both. Aortic root replacement was performed using a composite root replacement in 9 patients and valve-sparing techniques in 21 patients (remodeling in 8 patients and reimplantation in 13 patients). Eight patients underwent reoperation at a mean of 4.7 +/- 3.0 years after aortic surgery: 3 for aortic insufficiency, 2 for dissection, 2 for valve thrombosis, and 1 for a distal aneurysm. Adverse outcomes included reoperation in 8 patients, aneurysm in 1 patient, and death due to dissection or stroke in 3 patients. Variables associated with an adverse outcome included preoperative aortic insufficiency, valve replacement, and absence of angiotensin-converting enzyme inhibitor therapy. Patients with Marfan or Loeys-Dietz syndrome requiring surgery during childhood have a favorable long-term outcome. Those undergoing valve-sparing root replacement or mitral valve repair have a low risk for reoperation. Postoperative angiotensin-converting enzyme inhibitor therapy confers clinical benefit.

We retrospectively analyzed 28 years of experience with the Bentall procedure in patients with aortic valve, aortic root, and ascending aortic disease. Between March 1982 and December 2010, a total of 218 patients underwent the Bentall procedure using a composite valved conduit. The "inclusion technique" was used in 30 patients (13.8%), the "open-button technique" in 181 patients (83.0%), and the Cabrol technique in 7 patients (3.2%). The early mortality rate was 5.5% (12/218). The mean follow-up duration was 108.0±81.0 months (range: 1-329 months). Seven patients required re-operation, and 1 patient required stent graft insertion at the descending thoracic aorta for progression of aortic arch or descending thoracic aortic dissection or aneurysm after the first operation, and 5 of them had Marfan syndrome. Kaplan-Meier estimated survival rates at 1, 5, 10, 20, and 25 years were 90.4%, 82.7%, 77.6%, 65.3%, and 60.3%, respectively. Freedom from reoperation rates at 1, 5, 10, 20, and 25 years were 99.0%, 98.3%, 95.5%, 90.8%, and 90.8%, respectively. In our experience, the Bentall procedure provided optimal survival with improved functional status. The disease of the aorta may progress, especially in patients with Marfan syndrome. Therefore, careful follow-up with regular computed tomography angiograms should be performed in these patients.

In patients undergoing the Ross procedure, the right ventricular outflow tract (RVOT) conduit is inserted in an orthotopic position rather than in the more heterotopic position used in the repair of complex congenital RVOT obstruction. The study aim was to compare the authors' institutional mid-term experience of large-sized homografts (>19 mm) in patients with Ross and non-Ross RVOT reconstructions. The outcome was reviewed of all homografts implanted for Ross (n = 72) or non-Ross (n = 64) RVOT reconstruction at a single center between 1993 and 2012. Echocardiographic data were reviewed to evaluate valve performance. Homograft dysfunction was defined as RVOT obstruction with peak echo-Doppler gradient >40 mmHg and/or grade >III/IV conduit valve regurgitation. Homograft failure was defined as the need for conduit replacement or catheter or surgical reintervention. The age, body weight, conduit diameter and previous surgery were significantly higher in patients with Ross compared to the non-Ross group (p = 0.002, 0.003 and Ross, n = 17; non-Ross, n = 18). The data acquired showed actuarial survival, freedom from conduit dysfunction and conduit failure to be similar in both cohorts. Freedom from any type of reoperation was worse for the Ross group (58%) than for the non-Ross group (72%) (p = 0.05). During the first 15 years after Ross or non-Ross pulmonary homograft implantation, the survival rate, freedom from failure and dysfunction, and RVOT gradient were statistically similar. Freedom from any type of reoperation was significantly higher in the non-Ross group, however.

Modelling elderly cardiac patients decision making using Cognitive Work Analysis: identifying requirements for patient decision aids.

2015-06-01

Patients make various healthcare decisions on a daily basis. Such day-to-day decision making can have significant consequences on their own health, treatment, care, and costs. While decision aids (DAs) provide effective support in enhancing patient's decision making, to date there have been few studies examining patient's decision making process or exploring how the understanding of such decision processes can aid in extracting requirements for the design of DAs. This paper applies Cognitive Work Analysis (CWA) to analyse patient's decision making in order to inform requirements for supporting self-care decision making. This study uses focus groups to elicit information from elderly cardiovascular disease (CVD) patients concerning a range of decision situations they face on a daily basis. Specifically, the focus groups addressed issues related to the decision making of CVD in terms of medication compliance, pain, diet and exercise. The results of these focus groups are used to develop high level views using CWA. CWA framework decomposes the complex decision making problem to inform three approaches to DA design: one design based on high level requirements; one based on a normative model of decision-making for patients; and the third based on a range of heuristics that patients seem to use. CWA helps in extracting and synthesising decision making from different perspectives: decision processes, work organisation, patient competencies and strategies used in decision making. As decision making can be influenced by human behaviour like skills, rules and knowledge, it is argued that patients require support to different types of decision making. This paper also provides insights for designers in using CWA framework for the design of effective DAs to support patients in self-management. Copyright © 2015 Elsevier Ireland Ltd.

Intraoperative digital angiography is the procedure of choice for the peripheral vascular surgeon who wishes to evaluate his results before terminating anesthesia. Two operating suites at the John L. McClellan Memorial Veterans Hospital are equipped with permanent ceiling-mounted Philips C-arm fluoroscopes and share an ADAC 4100 digital angiographic system. In the last 18 months, 40 peripheral vascular intraoperative digital angiographic procedures have been performed, in all but two cases using direct arterial puncture. In 65% of cases, the intraoperative study showed no significant abnormality. In 12.5%, minor abnormalities not requiring reoperation were seen. In 22.5% of cases, the intraoperative digital angiogram revealed a significant abnormality requiring immediate operative revision. None of the patients who underwent reoperation experienced postoperative sequelae. Intraoperative digital angiography is useful in identifying complications of peripheral vascular operations

Thrombotic complications after percutaneous coronary intervention procedures have decreased in past years mainly due to the use of clopidogrel antiplatelet therapy. However, the risk of bleeding due to enhanced and irreversible platelet inhibition in patients who will require surgical coronary revascularization instead has not been adequately addressed in the literature. The purpose of this study was to evaluate the effect of pre-operative clopidrogel exposure in haemorrhage-related re-exploration rates, peri-operative transfusion requirements, morbidity, and mortality in patients undergoing coronary artery bypass grafting (CABG) surgery. A study population of 2359 patients undergoing isolated CABG between January 2000 and June 2002 was reviewed. Of these, 415 (17.6%) received clopidogrel prior to CABG surgery, and 1944 (82.4%) did not. A risk-adjusted logistic regression analysis was used to assess the association between clopidogrel pre-medication (vs. no) and haemostatic re-operation, intraoperative and post-operative blood transfusion rates, and multiple transfusions received. Haemorrhage-related pre-operative risk factors identified from the literature and those found significant in a univariate model were used. Furthermore, a sub-cohort, matched-pair by propensity scores analysis, was also conducted. The clopidogrel group had a higher likelihood of haemostatic re-operation [OR = 4.9, (95% CI, 2.63-8.97), P < 0.01], an increase in total packed red blood cell transfusions [OR = 2.2, (95% CI, 1.70-2.84), P < 0.01], multiple unit blood transfusions [OR = 1.9, (95% CI, 1.33-2.75), P < 0.01] and platelet transfusions [OR = 2.6, (95% CI, 1.95-3.56), P < 0.01]. Surgical outcomes and operative mortality [OR = 1.5, (95% CI, 0.36-6.51), P = 0.56] were not significantly different. Pre-operative clopidogrel exposure increases the risk of haemostatic re-operation and the requirements for blood and blood product transfusion during, and after, CABG surgery.

Previous work has suggested a failed irrigation and debridement (I&D) before a 2-stage exchange negatively impacts the outcome of the subsequent 2-stage revision. This was a retrospective review of 132 patients who underwent a 2-stage exchange without prior I&D (2-Stage), and 45 patients had a failed I&D before their 2-stage exchange (I&D+2Stage) between April 2009 and April 2015. Charts were reviewed for patient demographics, presenting inflammatory laboratory values, type of antibiotic spacer used, surgical details, microbiology data, length of postoperative antibiotic treatment, and reoperation. A logistic regression was used to assess the association between I&D and reoperation. The I&D+2Stage group had an 82.2% success rate, and the 2-Stage group had an 82.5% success rate (P = .95). The odds of reoperation for infection with the use of greater than 2 grams of vancomycin was 0.33 (P = .01, 95% confidence interval 0.14-0.79) as compared with having less than 2 grams of vancomycin in the construct. Spacer type, having a prior I&D to the 2-stage procedure, being infected with an antibiotic resistant organism, total grams of aminoglycoside were not associated with a risk of failure. Success rates between the I&D+2Stage group and the 2-Stage group were similar. The use of greater than 2 grams of vancomycin in the spacer construct decreased the odds of reoperation. I&D before a 2-stage exchange may not negatively influence the outcomes of a subsequent 2-stage revision procedure and requires further investigation. Copyright © 2017 Elsevier Inc.

Radiation therapy (RT) may pose acute and long-term risks for patients with cardiac implantable electronic devices (CIEDs), including pacemakers (PMs) and implantable cardioverter-defibrillators (ICDs). However, the frequency of these problems has not been accurately defined. The purpose of this study was to determine the prevalence of CIEDs among patients requiring RT and report the common CIED-related problems when patients are managed according to a standard clinical care path. In a single tertiary-care center, we prospectively screened all patients requiring RT and identified patients with ICDs or PMs. We collected clinical data about their cancer, RT treatment plan, and CIED. Radiation dose to the device was estimated in all patients, and any device malfunction during RT was documented. Of the 34,706 consecutive patients receiving RT, 261 patients (0.8%, mean age 77.9 ± 9.4 years) had an implantable cardiac device: 54 (20.7%) ICDs and 207 (79.3%) PMs. The site of RT was head and neck (27.4%), chest (30.0%), and abdomen/pelvis (32.6%). Using our care path, 63.2% of patients required continuous cardiac monitoring, 14.6% required device reprogramming, 18.8% required magnet application during RT, and 3.4% required device repositioning to the contralateral side before RT. Four patients (1.5%) had inappropriate device function during RT: 3 experienced hemodynamically tolerated ventricular pacing at the maximum sensor rate, and 1 experienced a device power-on-reset. No patient died or suffered permanent device failure. Nearly 1% of patients receiving RT in this series has a PM or ICD. However, with a systematic policy of risk assessment and patient management, significant device-related complications are rare. Copyright © 2015 Heart Rhythm Society. Published by Elsevier Inc.

Enabling Patient-Centred (PC) care in modern healthcare requires the flow of medical information with the patient between different healthcare providers as they follow the patient's treatment plan. However, PC care threatens the stability of the balance of information security in the support systems since legacy systems fall short of attaining a security balance when sharing their information due to compromises made between its availability, integrity, and confidentiality. Results show that the main reason for this is that information security implementation in discrete legacy systems focused mainly on information confidentiality and integrity leaving availability a challenge in collaboration. Through an empirical study using domain analysis, observations, and interviews, this paper identifies a need for six information security requirements in legacy systems to cope with this situation in order to attain the security balance in systems supporting PC care implementation in modern healthcare.

Premedication with clopidogrel has reduced thrombotic complications after percutaneous coronary revascularization procedures. However, because of the enhanced and irreversible platelet inhibition by clopidogrel, patients requiring surgical revascularization have a higher risk of bleeding complications and transfusion requirements. A principal benefit of surgical coronary revascularization without cardiopulmonary bypass is its lower hemorrhagic sequelae. The purpose of this study was to evaluate the effect of preoperative clopidogrel administration in the incidence of hemostatic reexploration, blood product transfusion rates, morbidity, and mortality in patients undergoing off-pump coronary artery bypass graft surgery using a large patient sample and a risk-adjusted approach. Two hundred eighty-one patients (17.9%) did and 1291 (82.1%) did not receive clopidogrel before their surgery, for a total of 1572 patients undergoing isolated off-pump coronary artery bypass graft surgery between January 2000 and June 2002. Risk-adjusted logistic regression analyses and a matched pair analyses by propensity scores were used to assess the association between clopidogrel administration and reoperation as a result of bleeding, intraoperative and postoperative blood transfusions received, and the need for multiple transfusions. Hemorrhage-related preoperative risk factors identified in the literature and those found significant in a univariate model were used. The clopidogrel group had a higher likelihood of hemostatic reoperations (odds ratio [OR], 5.1; 95% confidence interval [CI], 2.47 to 10.47; P<0.01) and an increased need in overall packed red blood cell (OR, 2.6; 95% CI, 1.94 to 3.60; P<0.01), multiple unit (OR, 1.6; 95% CI, 1.07 to 2.48; P=0.02), and platelet (OR, 2.5; 95% CI, 1.77 to 3.66; P<0.01) transfusions. Surgical outcomes and operative mortality (1.4% versus 1.4%; P=1.00) were not statistically different. Clopidogrel administration in the cardiology suite increases

The Ross/Ross-Konno procedure is considered a good option for irreparable aortic valve disease in pediatric patients because of its hemodynamic performance and potential for growth of the pulmonary autograft. This study is a review of the long-term results of our 20-year experience with the Ross and Ross-Konno operations in a single institution. Between June 1995 and January 2016, 16 consecutive patients (mean age, 6.0±5.9 years; range, 16 days to 17.4 years) underwent either a Ross operation (n=9) or a Ross-Konno operation (n=7). The study included 12 males and 4 females, with a median follow-up period of 47 months (range, 6 to 256 months). There were no cases of in-hospital or late mortality. Six reoperations were performed in 5 patients. Four patients underwent right ventricular-pulmonary artery (RV-PA) conduit replacement. Two patients underwent concomitant replacement of the pulmonary autograft and RV-PA conduit 10 years and 8 years after the Ross operation, respectively. The rate of freedom from adverse outcomes of the pulmonary autograft was 88% and 70% at 5 and 10 years, respectively. The rate of freedom from valve-related reoperations was 79% and 63% at 5 and 10 years, respectively. Pulmonary autografts demonstrated good durability with low mortality. The Ross/Ross-Konno procedure is a good option that can be performed safely in pediatric patients with aortic valve disease, even in a small-volume center.

This study aims to compare mid-long-term clinical outcomes between patients younger than 60 years of age undergoing bioprosthetic and mechanical aortic valve replacement. From January 2002 to December 2009, patients younger than 60 years of age who received Medtronic Hancock II porcine bioprostheses were selected and compared with those who received mechanical bi-leaflet valves in the aortic position. A stepwise logistic regression propensity score identified a subset of 112 evenly matched patient-pairs. Mid-long-term outcomes of survival, valve-related reoperations, thromboembolic events and bleeding events were assessed. The follow-up was only 95.1% complete. Fourteen measurable variables were statistically similar for the matched cohort. Postoperative in-hospital mortality was 3.6% (bioprosthetic valves) and 2.7% (mechanical valves) (P = 0.700). Survival at 5 and 10 years was 96.3 and 88.7% for patients receiving bioprosthetic valve replacement versus 96.3 and 87.9% for patients receiving mechanical valve replacement (P = 0.860), respectively. At 5 and 10 years after operations, freedom from valve-related reoperation was 97.2 and 94.8% for patients receiving mechanical valve replacement, and 96.3 and 90.2% for patients receiving bioprosthetic valve replacement (P = 0.296), respectively. There was no difference between freedom from thromboembolic events (P = 0.528) and bleeding events (P = 0.128) between the matched groups during the postoperative 10 years. In patients younger than 60 years of age undergoing aortic valve replacement, mid-long-term survival rate was similar for patients receiving bioprosthetic versus mechanical valve replacement. Bioprosthetic valves were associated with a trend for a lower risk of anticoagulation treatment and did not have significantly greater likelihood of a reoperation. These findings suggest that a bioprosthetic valve may be a reasonable choice for AVR in patients younger than 60 years of age. © The Author 2015. Published by

We sought to determine perioperative patterns of narcotic use and the prevalence of postoperative doctor shopping among patients with nephrolithiasis requiring operative management. We retrospectively reviewed the records of consecutive patients residing in Tennessee who required ureteroscopy with laser lithotripsy for nephrolithiasis at a single institution from January to December 2013. Using the Tennessee CSMD (Controlled Substances Medication Database) patients were categorized by the number of postoperative narcotic providers. Doctor shopping behavior was identified as any patient seeking more than 1 narcotic provider within 3 months of surgery. Demographic and clinical characteristics associated with doctor shopping behavior were identified. During the study period 200 eligible patients underwent ureteroscopy with laser lithotripsy for nephrolithiasis, of whom 48 (24%) were prescribed narcotics by more than 1 provider after surgery. Compared to those receiving narcotics from a single provider, patients with multiple narcotic providers were younger (48.1 vs 54.2 years, p shopping is common among patients with nephrolithiasis who require operative management. Urologists should be aware of available registry data to decrease the likelihood of redundant narcotic prescribing. Copyright © 2016 American Urological Association Education and Research, Inc.

Parkinson disease is the second most common neurodegenerative condition. The literature on patients with Parkinson disease and spine surgery is limited, but increased complications have been reported. All patients with Parkinson disease undergoing lumbar spine surgery between 2002 and 2012 were identified. Patients' charts, radiographs, and outcome questionnaires were reviewed. Parkinson disease severity was assessed with use of the modified Hoehn and Yahr staging scale. Complications and subsequent surgeries were analyzed. Risk for reoperation was assessed. Ninety-six patients underwent lumbar spine surgery. The mean patient age was 63.0 years. The mean follow-up duration was 30.1 months. The Parkinson disease severity stage was Parkinson disease severity stage of ≥3 (p Parkinson disease is good, with improvement of spine-related pain. A larger prospective study is warranted.

In primary hyperparathyroidism (PHPT) the predictive value of technetium 99m sestamibi single emission computed tomography (Tc99m-MIBI-SPECT) for localizing pathological parathyroid glands before a first parathyroidectomy (PTx) is 83-100%. Data are scarce in patients undergoing reoperative parathyroidectomy for persistent hyperparathyroidism. The aim of the present study was to determine the value of Tc99m-MIBI-SPECT in localizing residual hyperactive parathyroid tissue in patients with persistent primary hyperparathyroidism (PHPT) after initial excision of one or more pathological glands. We retrospectively evaluated the localizing accuracy of Tc99m-MIBI-SPECT scans in 19 consecutive patients with persistent PHPT who had a scan before reoperative parathyroidectomy. We used as controls 23 patients with sporadic PHPT who had a scan before initial surgery. In patients with persistent PHPT, Tc99m-MIBI-SPECT accurately localized a pathological parathyroid gland in 33% of cases before reoperative parathyroidectomy, compared to 61% before first PTx for sporadic PHPT. The Tc99m-MIBI-SPECT scan accurately localized intra-thyroidal glands in 2 of 7 cases and a mediastinal gland in 1 of 3 cases either before initial or reoperative parathyroidectomy. Our data suggest that the accuracy of Tc99m-MIBI-SPECT in localizing residual hyperactive glands is significantly lower before reoperative parathyroidectomy for persistent PHPT than before initial surgery for sporadic PHPT. These findings should be taken in consideration in the preoperative workup of patients with persistent primary hyperparathyroidism.

Endovascular treatment of the subclavian artery aneurysm in high-risk patient - a single-center experience

2016-01-01

Full Text Available We present our first experience with endovascular treatment of 6 subclavian artery aneurysms (SAA occurring in five male and one female patient. All patients, in our studies, according to ASA classification were high risk for open repair of SAA. The etiology of the all aneurysms was atherosclerosis degeneration of the artery. Two aneurysms were of intrathoracic location, then the other were extrathoracic. Symptoms related to subclavian artery aneurysms were present in two patients, compression and chest pain in one, and hemorrhage shock in second, while the remaining patients were asymptomatic. We preferred the Viabhan endoprosthesis for endovascular repair in 5 cases. In one patient with ruptured of subclavian artery aneurysm who was high-risk for open repair we made combined endovascular procedure. First at all, we covered the origin of left subclavian artery with thoracic stent graft and after that we put two coils in proximal part of subclavian artery. There was no operative mortality, and the early patency rate was 100%. The follow-up period was from 3 months to 3 years. During this period, one patient died of heart failure and one patient required endovascular reoperation due to endoleak type I. Endovascular treatment is recommended for all patients with subclavian artery aneurysm whenever this is possible due to anatomical reasons especially in high-risk patient with intrathoracic localization of aneurysm, to prevent potential complications.

The impending burden of revision shoulder arthroplasty has increased interest in outcomes of revision procedures. Painful glenoid arthrosis following hemiarthroplasty is a common cause of reoperation, and conversion to anatomic total shoulder arthroplasty is one option. We identified patients who underwent revision of painful hemiarthroplasty to total shoulder arthroplasty over a 15-year period in a single tertiary-care health system. Presurgical and operative data were analyzed for 28 patients who met the inclusion and exclusion criteria. Patients were contacted at a minimum of 2 years' follow-up after revision surgery for functional outcome scores, reoperations, and implant survival. The 2- and 5-year implant survival rates were 93% and 86%, respectively. Functional outcomes were obtained from 21 patients with surviving implants. The mean American Shoulder and Elbow Surgeons score, visual analog scale score for pain, and Single Assessment Numerical Evaluation score were 78 ± 20, 2.3 ± 2.6, and 71 ± 24, respectively. The mean Short Form 12 mental and physical scores were 49 ± 10 and 43 ± 9, respectively. Of the patients, 17 (81%) were either satisfied or very satisfied with their outcome. Complications were seen in 10 patients (36%), and 6 patients (21%) required reoperation. Anatomic total shoulder arthroplasty following hemiarthroplasty can achieve successful outcomes and implant survival rates. Given our poor understanding of reverse shoulder arthroplasty longevity, this procedure should remain an option for patients with glenoid arthrosis and an intact rotator cuff.

Wound infection remains a major source of postoperative morbidity leading to prolonged hospital stays and increased total cost, including indirect expenses related to the wound infection. We examined whether there is any higher risk of wound infection in patients undergo a reoperation after an initial operation or excision/incision biopsy. A retrospective review of medical charts of patients with breast operations between January 1990 and July 2008 was carried out. The overall incidence of wound infection was 18.2% (231/1267). The rate of wound infection was (32%) when reoperation was done after previous modified radical mastectomy, 18.9% and 16.8% when the previous operations were lumpectomy/segmenectomy with axillary dissection and simple mastectomy without axillary dissection, respectively and (10.8%) when reoperation was performed after previous biopsy. Reoperation involving axillary dissection was associated with significantly higher rates of wound infection (pprocedure affects the risk of wound infection in subsequent operation in patients with breast cancer. Significantly higher risks of wound infection are seen in those patients who had undergone axillary dissection or modified radical mastectomy.

Background and purpose: To report an early analysis of prospective study exploring preoperative radiotherapy and local excision in rectal cancer. Materials and methods: Mucosa at tumour edges was tattooed. Patients with cT1-3N0 tumour <3-4 cm were treated with either 5 x 5 Gy + 4 Gy boost (N = 31) or chemoradiation (50.4 Gy + 5.4 Gy boost, 1.8 Gy per fraction + 5-fluorouracyl and leucovorin; N = 13). Thirteen patients from the short-course group were unfit for chemotherapy. The interval from radiation to full-thickness local excision was 6 weeks. The protocol called for conversion to a transabdominal surgery in case of ypT2-3 disease or positive margin. Results: The postoperative complications requiring hospitalization were recorded in 9% of patients. The rate of pathological complete response was 41%. The rate of patients requiring conversion was 34%; however, 18% actually underwent conversion and the remaining 16% refused or were unfit. During the 14 months of median follow-up, local recurrence was detected in 7% of patients and all underwent salvage surgery. Of 19 patients in whom initially anterior resection was likely, 16% had abdominoperineal resection performed for a conversion or as a rescue procedure. Conclusion: Our study suggests that the short-course radiation prior to local excision is a treatment option for high-risk patients.

To evaluate the success rate of adjustable suture techniques in horizontal eye muscle surgery in children ≤15 years of age over a 19-year period by a single surgeon. The medical records of all consecutive patients in this age group who underwent horizontal eye muscle surgery from 1989 through 2012 were reviewed retrospectively. Patients were divided into two groups: those in whom a nonadjustable suture technique was used and those in whom adjustable sutures were used. The following data were collected: type of strabismus, preoperative measurements, postoperative results, and reoperation rates. A total of 116 cases in the nonadjustable group and 521 cases in the adjustable group were included. In the adjustable group, adjustment was performed in 63% of the cases, because of either an under- (41%) or overcorrection (22%). The adjustment procedure was performed under topical proparacaine in 15% of cases and under intravenous propofol in 85%. For the adjustable group, 3-5 minutes more per muscle intraoperatively and 15-20 minutes for adjustment were required. No complications were encountered during the adjustment procedures. Early success rate, defined as alignment within 8 Δ of straight at 3 to 6 months' postoperative follow-up, was significantly greater in the adjustable group than in the nonadjustable group (77.7% vs 64.6% [P ≤ 0.03]). Of the adjustable patients, 15% required reoperation compared with 21% of the nonadjustable patients. Use of adjustable sutures in horizontal eye muscle surgery in children ≤15 years of age provided an improved success rate and fewer reoperations compared with nonadjustable sutures.

Hickson, M; Fearnley, L; Thomas, J; Evans, S

2007-10-01

It has been consistently observed that a significant proportion of hospital inpatients are malnourished and many actually develop malnutrition in hospital. The NHS provides over 300 million meals each year at a cost of pound 500 million, yet there is relatively little research evaluating how well different catering systems provide for the needs of hospital inpatients. The aim of the study was to: (i) evaluate whether a new steam meal catering system (Steamplicity) enables patients in theory to meet their energy requirements in hospital and (ii) compare energy and protein intake using Steamplicity with a traditional bulk cook-chill system. Patients not at nutritional risk had their food intake at one lunchtime assessed. Energy intake was compared with the patients' energy requirements and energy and protein intake were compared with previous data from a bulk system. Fifty-seven patients had a median daily energy requirement of 7648 kJ (1821 kcal) [inter-quartile range (IQR): 6854-9164 kJ]. Assuming 30% [2293 kJ (546 kcal)] should be supplied by the lunch meal the average intake of 1369 kJ (326 kcal) fell short by 40%. Patients served meals from Steamplicity ate less energy [1369 kJ versus 1562 kJ (326 kcal versus 372 kcal) P = 0.04] but similar protein (18 g versus 19 g P = 0.34) to the bulk system. The largest difference was the energy provided by the dessert since the bulk system served more hot high-calorie desserts. Patient intakes did not meet their estimated requirements. The patients in this study were eating well and not at nutritional risk, thus patients with a poor appetite will be even less likely to meet their nutritional requirements. Steamplicity meals result in a lower energy intake than meals from a bulk cook-chill system, but similar protein intakes.

The search for an optimal patch material for aortic valve reconstruction (AVR) is an ongoing challenge. In this study, we report our experience of AVR using decellularized bovine pericardial patch material in congenital heart surgery. Data of 40 consecutive patients who underwent AVR using the CardioCel® patch (Admedus Regen Pty Ltd, Perth, WA, Australia) between February 2014 and August 2016 were retrospectively reviewed. The median age of the patients at operation was 9 (2-34) years, and 18 patients were younger than 7 years. Twenty-six patients initially presented with aortic valve insufficiency (AI) and 14 with stenosis. Clinical and echocardiographic data were available until August 2017 for a median postoperative follow-up (FU) of 22 (6-42) months. Nine of 40 (23%) patients experienced an event during FU (death: n = 1, 2.5%; reoperation: n = 8, 20%). Overall, the probability of freedom from reoperation or death was 97 ± 3%, 76 ± 9% and 57 ± 12% at 12, 24 and 36 months of FU, respectively. Reason for reoperation was stenosis in 3 (37.5%) patients, insufficiency in 4 (50%) patients and 1 (12.5%) patient was diagnosed with aortic valve endocarditis. Of the remaining 31 patients, 2 patients are scheduled for reoperation (aortic valve stenosis: n = 1 and AI: n = 1) and 9 patients exhibit worsening of aortic valve function with moderate AI. Freedom from developing combined end point [death/reoperation/moderate degree of aortic valve dysfunction (aortic valve stenosis, AI)] after AVR was 92 ± 5%, 55 ± 9% and 28 ± 9% at 12, 24 and 36 months, respectively. AVR using decellularized bovine pericardial patch material in patients with congenital aortic valve disease show unsatisfactory results within the first 3 years of FU.

The use of antithrombotic agents such as anticoagulants and antiplatelet agents is widespread, and the opportunities to treat patients with chronic subdural hematoma (CSDH) under antithrombotic therapy are growing. However, whether antithrombotic therapy contributes to postoperative complications and recurrences of CSDH and how these agents should be managed in the surgical treatment of CSDH remains unclear. We retrospectively analyzed 150 consecutive patients with CSDH who underwent neurosurgical interventions at Kyushu Rosai Hospital from 2011 to 2015 and followed them for more than 3 months. Of the 150 study patients, 44 received antithrombotic therapy. All anticoagulants and 76% of the antiplatelet agents were discontinued before surgical treatment of CSDH and resumed within 1 week except in 4 patients whose treatment was terminated and 7 patients who developed postoperative complications or underwent reoperations before resumption of these agents. Postoperative hemorrhagic complications associated with surgical treatment of CSDH occurred in 8 patients (5.3%), and there was no significant difference in the incidence of these complications between patients with and without antithrombotic therapy (6.8% vs. 4.7%, respectively; p=0.90). Postoperative thromboembolic complications occurred in 5 patients (5.4%), including 4 patients with antithrombotic therapy; these complications developed before resumption of antithrombotic agents in 2 patients. There was a significant difference in the incidence of postoperative thromboembolic complications between patients with and without antithrombotic therapy (9.1% vs. 0.9%, respectively; p=0.04). There were no significant differences in the incidence of radiographic deterioration or reoperation of ipsilateral or contralateral hematomas between patients with and without antithrombotic therapy after surgical treatment of unilateral CSDH. A history of antithrombotic therapy was significantly correlated with the incidence of

Full Text Available BACKGROUND: After cardiomyotomy for the treatment of megaesophagus, recurrence of symptoms occur in up to 15% of the patients, but only some require a reoperation. AIM: To evaluate the results of reoperation - cardioplasty with Roux-en-Y partial gastrectomy, a technique proposed by Serra-Dória. CASUISTIC AND METHODS: Twenty patients with achalasia previously treated by cardiomyotomy, were retrospectively studied. The etiology of symptoms recurrence was reflux esophagitis in nine (45.0% patients, healing of the myotomy in five (25.0%, end staging megaesophagus in five (25.0% and incomplete myotomy in one (5%. Intra and postoperative complications were analyzed. The patients were studied by clinical (dysphagia, regurgitation, heartburn and weight gain, radiological and endoscopic evaluation, in the pre- and postoperative period. RESULTS: Five (25.0% patients had complications in the immediate postoperative period. No deaths were observed. Dysphagia improved in all the patients. Regurgitation and heartburn almost disappeared in the whole group. Weight was maintained or increased in 64.7% of the patients. Radiological studies showed a decrease in the caliber of the esophagus in 53.0%, while the remaining patients maintained the pre-operative diameter. Endoscopy, performed during the late postoperative period in 17 patients, showed that 6 among the 9 with reflux esophagitis improved; 2 among the 8 with a normal esophagus during the preoperative period, developed esophagitis. CONCLUSIONS: The Serra-Dória procedure for the treatment of megaesophagus in patients who had already undergone cardiomyotomy and whose symptoms recurred, presented a low morbidity and no mortality. It offered a significant relief of symptoms with a decrease of the caliber of the esophagus in several patients. The patients also improved with regards to reflux esophagitis. In some cases reflux was still present after surgery. Others with normal esophagus in the preoperative

Patients with intracranial tumour are usually on anticonvulsants. Patients on phenytoin therapy demonstrate rapid metabolism of nondepolarising muscle relaxants secondary to enzyme induction. Infusion dose requirement of rocuronium in such patients has been sparingly studied. We studied the continuous infusion dose requirement of rocuronium bromide in patients on phenytoin therapy and its correlation with serum levels of phenytoin. Seventy-five patients scheduled for supratentorial tumour surgery were included in the study. Patients not on phenytoin were taken as control. The primary outcome variable studied was the infusion dose requirement of rocuronium in patients on phenytoin. Based on pre-operative serum phenytoin levels, study group patients were divided into two groups: sub-therapeutic level group (phenytoin level 10 μg/mL). Following anaesthesia induction, rocuronium bromide 0.6 mg/kg was administered to achieve tracheal intubation. Rocuronium infusion was titrated to maintain zero response on the train-of-four response. Demographic data were comparable. Patients receiving phenytoin required higher infusion dose compared to the control group (0.429 ± 0.2 mg/kg/h vs. 0.265 ± 0.15 mg/kg/h, P rocuronium (0.429 ± 0.205 mg/kg/h vs. 0.429 ± 0.265 mg/kg/h ( P = 0.815). The recovery was faster in the phenytoin group compared to the control group. Haowever, it was not clinically significant. The infusion dose requirement of rocuronium bromide in patients on phenytoin is higher and the serum levels of phenytoin does not influence the dose required.

The objectives of the present study were to find out the results and the factors affecting survival after primary knee arthroplasty with a cruciate-retaining prosthesis in severe valgus deformity. Forty-eight patients (52 knees) participated in the current follow-up study. All patients were followed at least 5 years or to first revision. Mean follow-up time was 9 years (range, 1 to 17 years).The Kaplan-Meier analysis revealed 79% (95% CI 68% to 91%) survival rate with revision for any reason and 81% (95% CI 70% to 93%) survival rate with revision for instability as an endpoint at 10 years. Preoperatively TFA was 23° (range, 15°-51°) in valgus and 7° (range, 21° valgus-4° varus) in valgus postoperatively. Of the 14 re-operated patients, eight were revised because of progressive postoperative medial collateral ligament instability. All re-operations were performed during the first 4 years of the follow-up. The mean TFA was 15.5° valgus postoperatively for those eight and the odds ratio for a revision was 2 (95% CI 1-3, p = 0.025) when compared to the rest of the study population. The residual valgus deformity increases the risk of re-operation and it should be avoided. If proper soft-tissue balance cannot be achieved or there is no functional medial collateral ligament present more constrained implants should be used. In selected cases where both bony correction and ligament balancing have properly been achieved the use of a cruciate-retaining type of prosthesis is justified. Copyright © 2010 Elsevier B.V.

We assessed the outcome in patients with Marfan syndrome operated on exclusively with the aortic valve-sparing reimplantation technique for aortic root aneurysms during more than a decade. Between July 1993 and April 2005, the aortic valve-sparing reimplantation technique (David I) was used in 325 patients. In 59 patients with clinical evidence of Marfan syndrome, procedures were done for aortic root aneurysm (n = 55) or aortic dissection type A (n = 4). Their mean age was 30 +/- 12 years (range, 9 to 62 years), and 37 (63%) were male. Additional procedures were arch replacement in 4 patients, coronary artery bypass grafting in 1, mitral valve surgery in 9, and closure of atrial septal defect in 3. Mean follow-up was 54 +/- 37 months (range, 0 to 139 months). No patient died during the first 30 days postoperatively. Mean bypass time was 163 +/- 34 minutes (range, 99 to 248 minutes), and mean aortic cross clamp time was 126 +/- 28 minutes (range, 78 to 202 minutes). Four patients (6.8%) required rethoracotomy for postoperative bleeding. Five late deaths (8.5%) occurred during follow-up. Reoperation of the reconstructed valve was required in 7 patients. Freedom from reoperation was 88% +/- 5% at 5 years and 80% +/- 9% at 10 years. Mean grade of aortic insufficiency was 1.81 preoperatively compared with 0.20 early postoperatively (p valve should encourage use of this technique in patients with Marfan syndrome.

Full Text Available Objective: The objective of the present study is to determine the incidence of delirium and the associated factors in patients undergoing open heart surgery. Methods: This is an Analytic-descriptive study conducted on 404 patients undergoing elective open heart surgery in Fatemeh Zahra Heart Center, Sari, over the period of 6 months from July to December 2011. Sampling was achieved in a nonrandomized targeted manner and delirium was assessed using NeeCham questionnaire. A trained nurse evaluated the patients for delirium and completed the risk factor checklist on days 1 to 5 after surgery. Data analyses were accomplished using survival analysis (Kaplan-Meier and Cox regression on SPSS software version 15. Results: We found that variables, including ventilation time, increased drainage during the first 24 hours, the need for re-operation in the first 24 hours, dysrhythmias, use of inotropic agents, increased use of analgesics, increased arterial carbon dioxide, lack of visitors, and use of physical restrainers were associated with the development of delirium. In addition, we found a delirium incidence of 29%. Conclusion: Diagnosis of cognitive disorders is of utmost value; therefore, further studies are required to clarify the risk factors because controlling them will help prevent delirium.

Enhancing requirements engineering for patient registry software systems with evidence-based components.

Patient registries are instrumental for medical research. Often their structures are complex and their implementations use composite software systems to meet the wide spectrum of challenges. Commercial and open-source systems are available for registry implementation, but many research groups develop their own systems. Methodological approaches in the selection of software as well as the construction of proprietary systems are needed. We propose an evidence-based checklist, summarizing essential items for patient registry software systems (CIPROS), to accelerate the requirements engineering process. Requirements engineering activities for software systems follow traditional software requirements elicitation methods, general software requirements specification (SRS) templates, and standards. We performed a multistep procedure to develop a specific evidence-based CIPROS checklist: (1) A systematic literature review to build a comprehensive collection of technical concepts, (2) a qualitative content analysis to define a catalogue of relevant criteria, and (3) a checklist to construct a minimal appraisal standard. CIPROS is based on 64 publications and covers twelve sections with a total of 72 items. CIPROS also defines software requirements. Comparing CIPROS with traditional software requirements elicitation methods, SRS templates and standards show a broad consensus but differences in issues regarding registry-specific aspects. Using an evidence-based approach to requirements engineering for registry software adds aspects to the traditional methods and accelerates the software engineering process for registry software. The method we used to construct CIPROS serves as a potential template for creating evidence-based checklists in other fields. The CIPROS list supports developers in assessing requirements for existing systems and formulating requirements for their own systems, while strengthening the reporting of patient registry software system descriptions.

The importance of adequate nutritional support is well established, but characterising what 'adequate nutrition' represents remains contentious. In recent years there has been increasing interest in the concept of 'permissive underfeeding' where patients are intentionally prescribed less nutrition than their calculated requirements. The aim of this study was to evaluate the effect of permissive underfeeding on septic and nutrition related morbidity in patients requiring short term parenteral nutrition (PN). This was a single-blinded randomised clinical trial of 50 consecutive patients requiring parenteral nutritional support. Patients were randomized to receive either normocaloric or hypocaloric feeding (respectively 100% vs. 60% of estimated requirements). The primary end point was septic complications. Secondary end points included the metabolic, physiological and clinical outcomes to the two feeding protocols. Permissive underfeeding was associated with fewer septic complications (3 vs. 12 patients; p = 0.003), and a lower incidence of the systemic inflammatory response syndrome (9 vs. 16 patients; p = 0.017). Permissively underfed patients had fewer feed related complications (2 vs. 9 patients; p = 0.016). Permissive underfeeding in patients requiring short term PN appears to be safe and may results in reduced septic and feed-related complications.

Controversy persists regarding the perioperative management of clopidogrel among patients undergoing carotid endarterectomy (CEA). This study examined the effect of preoperative dual antiplatelet therapy (aspirin and clopidogrel) on in-hospital CEA outcomes. Patients undergoing CEA in the Vascular Quality Initiative were analyzed (2003-2014). Patients on clopidogrel and aspirin (dual therapy) were compared with patients taking aspirin alone preoperatively. Study outcomes included reoperation for bleeding and thrombotic complications defined as transient ischemic attack (TIA), stroke, or myocardial infarction. Secondary outcomes were in-hospital death and composite stroke/death. Univariate and multivariable analyses assessed differences in demographics and operative factors. Propensity score-matched cohorts were derived to control for subgroup heterogeneity. Of 28,683 CEAs, 21,624 patients (75%) were on aspirin and 7059 (25%) were on dual therapy. Patients on dual therapy were more likely to have multiple comorbidities, including coronary artery disease (P < .001), congestive heart failure (P < .001), and diabetes (P < .001). Patients on dual therapy were also more likely to have a drain placed (P < .001) and receive protamine during CEA (P < .001). Multivariable analysis showed that dual therapy was independently associated with increased reoperation for bleeding (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.20-2.42; P = .003) but was protective against TIA or stroke (OR, 0.61; 95% CI, 0.43-0.87; P = .007), stroke (OR, 0.63; 95% CI, 0.41-0.97; P = .03), and stroke/death (OR, 0.66; 95% CI, 0.44-0.98; P = .04). Propensity score matching yielded two groups of 4548 patients and showed that patients on dual therapy were more likely to require reoperation for bleeding (1.3% vs 0.7%; P = .004) but less likely to suffer TIA or stroke (0.9% vs 1.6%; P = .002), stroke (0.6% vs 1.0%; P = .04), or stroke/death (0.7% vs 1.2%; P = .03).

Patients with Noonan syndrome often require surgery at young ages. They are at high risk of perioperative bleeding from coagulation defects that might not have been detected by routine screening. These risks are rarely described in the oral and maxillofacial surgery (OMS) literature. The aim of this study was to evaluate the perioperative bleeding risks associated with Noonan syndrome and to propose preoperative guidelines. This report describes a retrospective case series of patients with Noonan syndrome who underwent OMS procedures during a continuous observational period (2013 through 2016) in the authors' center. Clinical data, blood screening test results, and perioperative bleeding were analyzed. Five patients (age, 4 to 20 yr) with Noonan syndrome who underwent OMS procedures were included in this study. One patient presented a spontaneous bleeding tendency (epistaxis requiring cauterization). Blood screening showed clotting defects in 3 patients. One patient presented abnormal perioperative bleeding owing to a mild defect in factor XI. Patients with Noonan syndrome must be referred to a hematologist for specific preoperative investigations and for adapted perioperative management.

To compare selected outcomes (30-day reoperation and total length of hospital stay) following emergency appendectomy between populations from New York State and England. This retrospective cohort study used demographic and in-hospital outcome data from Hospital Episode Statistics (HES) and the New York Statewide Planning and Research Cooperative System (SPARCS) administrative databases for all patients aged 18+ years undergoing appendectomy between April 2009 and March 2014. Univariate and adjusted multivariable logistic regression were used to test significant factors. A one-to-one propensity score matched dataset was created to compare odd ratios (OR) of reoperations between the two populations. A total of 188,418 patient records, 121,428 (64.4%) from England and 66,990 (35.6%) from NYS, were extracted. Appendectomy was completed laparoscopically in 77.7% of patients in New York State compared to 53.6% in England (P New York State, respectively. All 30-day reoperation rates were higher in England compared to New York State (1.2 vs. 0.6%, P New York State. Increasing the numbers of appendectomy completed laparoscopically may decrease length of stay and reoperations.

The optimal prosthesis option for aortic valve replacement in adult patientsreplacement (n=190; 86%) or the subcoronary technique (n=31; 14%). There were 169 patients with bicuspid valves and 33 redo operations including previous aortic valve repair (n=6) and replacement (n=9) for severe AS. Demographic, preoperative, postoperative and longitudinal clinical and echocardiographic data were collected prospectively. The median and mean follow-up were 11.4 years (range: 1-20.1 years) and 10.1±5.9 years, respectively. The follow-up was complete in all patients. Kaplan-Meier actuarial survival analysis was performed to assess long-term survival, freedom from reoperation for autograft and/or homograft failure and freedom from autograft valve insufficiency. Cox regression risk analysis was performed to identify factors associated with autograft or homograft reoperations. The perioperative mortality rate was 0.9% (n=2). The incidence rate of early reoperation for bleeding was 5.9%. The actuarial survival rate at 10 and 15 years following surgery was 92.1 and 90.5%, respectively. Ross-related reoperations occurred in 21 patients during follow-up: autograft dysfunction (n=9), homograft dysfunction (n=6) and both (n=6). The rate of freedom from Ross-related reoperation was 94.7 and 87.7% at 10 and 15 years, respectively. The rate of freedom from reoperation for autograft failure was 97.6 and 91.5%, the rate of freedom from reoperation for homograft failure was 95.7 and 90.8%, and the rate of freedom from moderate or severe autograft regurgitation was 94.1 and 85.6% at 10 and 15 years, respectively. Compared with available aortic bioprosthetic alternatives in young adults with severe AS, the Ross procedure provides an excellent long-term option for patients with predominant severe AS who seek a durable operation without anticoagulation. © The Author 2014.

Purpose: Treatment of 131I thyroid cancer patients who also require regular hemodialysis (HD) treatments requires consideration of the administered activity and the HD schedule. In this work the red bone marrow is considered the dose limiting organ and the treatment plan optimized the HD schedule with the amount of radioactivity administered. Methods: The ‘Safe’ dose was considered to be 2 Gy (200 rad) to the red bone marrow.1 131Iodine doses of 50 mCi to 100 mCi were modeled and found to require a range of HD schedules. In order to achieve the safe dose to the red marrow, more aggressive HD schedules are required. 100 mCi required an aggressive HD treatment of every 24 hours for at least one week to achieve the ‘safe’ dose and an exposure appropriate for release from the hospital. A more normal schedule of HD beginning at 18 hours then every 48 hours allowed for up to 60 mCi administered dose allowed for a safe dose and expected release after less than one week.2In addition room was equipped with video cameras cameras for monitoring the patient and their vital signs from an adjacent room during HD. In this way the dialysis nurses were able to monitor the patient closely from an adjoining room. Results: Two HD patients were administered adjusted doses of about 50 mCi. The medical and nursing staff were exposed to no more than 4 mR for the entire treatment. The residual Iodine in the patient appeared to be normal after 4 to 6 days when the patient was released. Conclusion: With careful treatment planning 131Iodine treatments can be performed safely for patients needing HD and treatments appear to be as effective as those for patients with normal renal function.

The aim of the present study was to investigate the rate of post-tonsillectomy hemorrhage (PTH) in a single institution and to evaluate the clinical risk factors for PTH. We reviewed the records of 692 patients who underwent tonsillectomy (TE) at Yokohama Minami Kyosai Hospital in Japan. PTH grades were grouped into three categories according to the severity of the hemorrhagic episode: (I) minimal hemorrhage that stopped after noninvasive treatment, (II) hemorrhage requiring treatment with local anesthesia, and (III) hemorrhage requiring reoperation under general anesthesia in the operating room. Clinical risk factors such as sex, age (adults vs. children), TE indication, surgeon's skill level, operative time, ligature type, and duration of antibiotic administration for PTH were investigated. Among the 692 patients, 80 (11.6%) showed PTH, with primary and secondary hemorrhage accounting for 1.6% and 10.0%, respectively. A category III PTH was observed in 18 patients; thus, the overall risk of reoperation was 2.6%. The PTH episode most frequently occurred on postoperative days 5 and 6. The frequency of PTH was significantly higher in male patients and in adults (Pdefinition of PTH. Clinical risk factors for PTH were adult age and male gender. The surgeon's skill level was an additional risk factor for category III PTH. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

We aimed to characterize the occurrence of postoperative hematoma (POH) after neurosurgery overall and according to procedure type and describe the prevalence of possible confounders. Patient data between 2010 and 2012 at the Department of Neurosurgery in Helsinki University Hospital were retrospectively analyzed. A data search was performed according to the type of surgery including craniotomies; shunt procedures, spine surgery, and spinal cord stimulator implantation. We analyzed basic preoperative characteristics, as well as data about the initial intervention, perioperative period, revision operation and neurologic recovery (after craniotomy only). The overall incidence of POH requiring reoperation was 0.6% (n = 56/8783) to 0.6% (n = 26/4726) after craniotomy, 0% (n = 0/928) after shunting procedure, 1.1% (n = 30/2870) after spine surgery, and 0% (n = 0/259) after implantation of a spinal cord stimulator. Craniotomy types with higher POH incidence were decompressive craniectomy (7.9%, n = 7/89), cranioplasty (3.6%, n = 4/112), bypass surgery (1.7%, n = 1/60), and epidural hematoma evacuation (1.6%, n = 1/64). After spinal surgery, POH was observed in 1.1% of cervical and 2.1% of thoracolumbar operations, whereas 46.7% were multilevel procedures. 64.3% of patients with POH and 84.6% of patients undergoing craniotomy had postoperative hypertension (systolic blood pressure >160 mm Hg or lower if indicated). Poor outcome (Glasgow Outcome Scale score 1-3), whereas death at 6 months after craniotomy was detected in 40.9% and 21.7%. respectively, of patients with POH who underwent craniotomy. POH after neurosurgery was rare in this series but was associated with poor outcome. Identification of risk factors of bleeding, and avoiding them, if possible, might decrease the incidence of POH.

OBJECTIVE Previous meta-analysis has demonstrated that the most important factor in seizure freedom following surgery for focal cortical dysplasia (FCD) is completeness of resection. However, intraoperative detection of epileptogenic dysplastic cortical tissue remains a challenge, potentially leading to a partial resection and the need for reoperation. The objective of this study was to determine the role of intraoperative MRI (iMRI) in the intraoperative detection and localization of FCD as well as its impact on surgical decision making, completeness of resection, and seizure control outcomes. METHODS The authors retrospectively reviewed the medical records of pediatric patients who underwent iMRI-assisted resection of FCD at the Children's National Health System between January 2014 and April 2015. Data reviewed included demographics, length of surgery, details of iMRI acquisition, postoperative seizure freedom, and complications. Postsurgical seizure outcome was assessed utilizing the Engel Epilepsy Surgery Outcome Scale. RESULTS Twelve consecutive pediatric patients (8 females and 4 males) underwent iMRI-guided resection of FCD lesions. The mean age at the time of surgery was 8.8 years ± 1.6 years (range 0.7 to 18.8 years), and the mean duration of follow up was 3.5 months ± 1.0 month. The mean age at seizure onset was 2.8 years ± 1.0 year (range birth to 9.0 years). Two patients had Type 1 FCD, 5 patients had Type 2A FCD, 2 patients had Type 2B FCD, and 3 patients had FCD of undetermined classification. iMRI findings impacted intraoperative surgical decision making in 5 (42%) of the 12 patients, who then underwent further exploration of the resection cavity. At the time of the last postoperative follow-up, 11 (92%) of the 12 patients were seizure free (Engel Class I). No patients underwent reoperation following iMRI-guided surgery. CONCLUSIONS iMRI-guided resection of FCD in pediatric patients precluded the need for repeat surgery. Furthermore, it resulted

Laparoscopy is increasingly utilised in the trauma setting. However, its safety and reliability in evaluating and managing retroperitoneal injuries are not known. The aim of this study was to analyse our experience with laparoscopic management of retroperitoneal injuries due to penetrating abdominal trauma (PAT) and to investigate its feasibility, safety and accuracy in haemodynamically stable patients. Over a 4-year period, patients approached laparoscopically with retroperitoneal injuries were analysed. Mechanism, location and severity of injuries were recorded. Surgical procedures, conversion rate and reasons for conversion and outcomes were described. Of the 284 patients with PAT, 56 patients had involvement of retroperitoneum. Stab wounds accounted 62.5% of patients. The mean Injury Severity Score was 7.4 (4-20). Among retroperitoneal injuries, the colon (27%) was the most commonly involved hollow viscera followed by duodenum (5%). The kidney (5%) and the pancreas (4%) were the injured solid organs. The conversion rate was 19.6% and was mainly due to active bleeding (73%). Significantly more patients with gunshot wound were converted to laparotomy (38% vs. 9%). Therapeutic laparoscopy was performed in 36% of patients. There were no recorded missed injuries or mortality. Five (9%) patients developed the Clavien-Dindo Grade 3 complications, three were managed with reoperation, one with drainage/debridement and one with endovascular technique. Laparoscopic management of retroperitoneal injuries is safe and feasible in haemodynamically stable patients with PAT. However, a high conversion rate indicates difficulties in managing these injuries. The requirements are the dexterity in laparoscopy and readiness to convert in the event of bleeding.

The study aim was to compare long-term results of Marfan syndrome (MFS) patients affected by aortic root disease undergoing aortic root replacement with the Bentall or David operation. Since 1994, a total of 59 patients has been followed at the authors' Marfan Center, having undergone either a Bentall operation (Bentall group, n = 30) or a David operation (David group, n = 29). No operative mortality was recorded. After 20 years (mean follow up 97 ± 82 months; range 1 to 369 months) no prosthesis-related major bleeding or thromboembolic events had been observed; the 20-year survival was 94 ± 6% in the Bentall group, and 100% in the David group (p = 0.32). Freedom from reintervention for aortic valve dysfunction was 100% in the Bentall group, and 75 ± 13% in the David group (p = 0.04). This inter-group difference became relevant after the first eight-year period of follow-up, and was mainly associated with a particular familiar genetic phenotype involving three out of four reoperated patients. Freedom from all-cause death, myocardial infarction, stroke, prosthetic valve-related complications, and reintervention on any aortic segment was 69 ± 12% in the Bentall group, and 67 ± 14% in the David group (p = 0.33). The Bentall and David operations are both associated with satisfactory long-term results in MFS patients. The low rate of valve prosthesis-related complications suggested that the Bentall operation would continue to be a standard surgical treatment. The reimplantation technique, adopted for less-dilated aortas, provides satisfactory freedom from reoperation. Careful attention should be paid to the reimplantation technique in patients affected by a serious familiar genetic phenotype.

Nitrogen Balance and Protein Requirements for Critically Ill Older Patients

Full Text Available Critically ill older patients with sarcopenia experience greater morbidity and mortality than younger patients. It is anticipated that unabated protein catabolism would be detrimental for the critically ill older patient. Healthy older subjects experience a diminished response to protein supplementation when compared to their younger counterparts, but this anabolic resistance can be overcome by increasing protein intake. Preliminary evidence suggests that older patients may respond differently to protein intake than younger patients during critical illness as well. If sufficient protein intake is given, older patients can achieve a similar nitrogen accretion response as younger patients even during critical illness. However, there is concern among some clinicians that increasing protein intake in older patients during critical illness may lead to azotemia due to decreased renal functional reserve which may augment the propensity towards worsened renal function and worsened clinical outcomes. Current evidence regarding protein requirements, nitrogen balance, ureagenesis, and clinical outcomes during nutritional therapy for critically ill older patients is reviewed.

The David aortic valve-sparing reimplantation (AVr-D) operation is increasingly being used in patients with aortic root aneurysmal disease and pliable aortic cusps. The objective of this study was to assess our early and medium-term outcomes with the AVr-D operation. Between 2003 and 2011, a total of 179 patients underwent AVr-D procedures. The mean patient age was 49.7 ± 15.1 years, and 23.5% (n = 42) were females. Marfan syndrome was present in 17.3% of patients (n = 31), and acute Type A aortic dissection in 15.6% (n = 28). Clinical follow-up was 100% complete and was 1.8 ± 1.6 years (0 days to 7.5 years) long. Echocardiographic follow-up was performed 2.2 ± 1.5 years (0 days to 7.5 years) postoperatively and was 77% complete. Early mortality was 1.1% (n = 2), with both deaths occurring in patients with Type A dissection. Pre-discharge echocardiography revealed no patients with >2+ aortic insufficiency (AI), 19.6% of patients (n = 34) with 1+ or 2+ AI and 80.4% of patients (n = 145) with trace or no AI. Left ventricular end-diastolic diameters decreased significantly from 5.6 ± 0.9 to 5.1 ± 0.8 cm early postoperatively (P valve re-replacement during follow-up, two due to early endocarditis and two due to non-coronary leaflet prolapse in Marfan patients. Five-year freedom from aortic valve reoperation was 95.9 ± 2.0%. AVr-D is associated with a low mortality and morbidity rate, even in patients with Type A aortic dissection. Although a slightly higher rate of recurrent AI may be present in patients with Marfan syndrome, freedom from recurrent AI and reoperation remains excellent during medium-term follow-up. The David operation should be considered the gold standard for patients with proximal aortic root pathology (aneurysm or dissection) and pliable aortic cusps.

Several patient-, procedure-, and prescriber-related factors are thought to influence the decision to administer allogeneic blood products. We reexamine a number of assertions applied commonly to the practice of transfusion in cardiac operations. More than 50 original articles including a total of more than 10,000 patients from 70 centers were reviewed. Data from 5,426 patients operated on between 1990 and 1994 at the Montreal Heart Institute are presented. From our review of the literature, we conclude that postoperative mediastinal fluid drainage averages 917 mL and that aspirin therapy increases drainage by less than 300 mL in most studies, which should not increase use of blood products, insofar as a strict transfusional protocol is adhered to. Across centers, transfusions can vary eightfold for the same postoperative drainage. Data from our institution show that postoperative mediastinal drainage per se is not influenced by reoperation or by the type of operation. However, total blood losses and transfusion requirements remain increased in reoperative and complex procedures. Excessive mediastinal drainage resulting in increased transfusions occurs in 29% of patients. Exposure to allogeneic transfusions remains institution dependent. Constant reevaluation of local practice is essential to implement efficient blood conservation strategies.

There is controversy about whether the dietary protein requirement of 1.2 g/kg/d for hemodialysis (HD) patients, in the nutritional guidelines recommended by the National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI), is reasonable. A cross-sectional study was conducted in 129 stable HD patients without diabetes (84 men, 45 women) to investigate the association between the protein equivalent of nitrogen appearance normalized by ideal body weight (nPNAibw), an index of protein intake, and skeletal muscle mass or other metabolic consequences. Patients were divided into 5 groups according to nPNAibw index. Midthigh muscle area (TMA), midthigh subcutaneous fat area (TSFA), abdominal muscle area (AMA), abdominal subcutaneous fat area (ASFA), and visceral fat area (AVFA) were measured using computed tomography, and various nutritional parameters were compared among these groups. TMA and AMA values increased with increasing dietary protein intake from less than 0.7 g/kg/d to 0.9-1.1 g/kg/d and showed a plateau at greater than 0.9 to 1.1 g/kg/d of dietary protein intake. Conversely, fat mass, including TSFA, ASFA, and AVFA, and serum potassium concentration increased with graded protein intake, and no plateau was formed. Patients with nPNAibw greater than 1.3 g/kg/d satisfied the criterion of visceral obesity. Although serum prealbumin levels showed a trend similar to that of muscle mass, there was no significant difference in serum albumin levels among the study groups. Optimal dietary protein requirement for patients undergoing maintenance HD in a stable condition appears to be less than the level recommended by the NKF-KDOQI nutritional guidelines.

To assess the ability of the recently developed adult spinal deformity frailty index (ASD-FI) to predict odds of perioperative complications, odds of reoperation, and length of hospital stay after adult spinal deformity (ASD) surgery using a database other than the one used to create the index. We used the ASD-FI to calculate frailty scores for 266 ASD patients who had minimum postoperative follow-up of 2 years in the European Spine Study Group (ESSG) database. Patients were enrolled from 2012 through 2013. Using ASD-FI scores, we categorized patients as not frail (NF) ( 0.5 points). Multivariable logistic regression, adjusted for preoperative and surgical factors such as operative time and blood loss, was performed to determine the relationship between ASD-FI category and odds of major complications, odds of reoperation, and length of hospital stay. We categorized 135 patients (51%) as NF, 90 patients (34%) as frail, and 41 patients (15%) as SF. Overall mean ASD-FI score was 0.29 (range 0-0.8). The adjusted odds of experiencing a major intraoperative or postoperative complication (OR 4.5, 95% CI 2.0-10) or having a reoperation (OR 3.9, 95% CI 1.7-8.9) were higher for SF patients compared with NF patients. Mean hospital stay was 2.1 times longer (95% CI 1.8-2.4) for SF patients compared with NF patients. Greater patient frailty, as measured by the ASD-FI, is associated with longer hospital stays and greater odds of major complications and reoperation.

Cancer patients requiring mechanical ventilation are widely viewed as poor candidates for intensive care unit (ICU) admission. We designed a prospective study evaluating a new admission policy titled The ICU Trial. Prospective study. Intensive care unit. One hundred eighty-eight patients requiring mechanical ventilation and having at least one other organ failure. Over a 3-yr period, all patients with hematologic malignancies or solid tumors proposed for ICU admission underwent a triage procedure. Bedridden patients and patients in whom palliative care was the only cancer treatment option were not admitted to the ICU. Patients at earliest phase of the malignancy (diagnosis ventilation, vasopressors, or dialysis after 3 days in the ICU died. Survival was 40% in mechanically ventilated cancer patients who survived to day 5 and 21.8% overall. If these results are confirmed in future interventional studies, we recommend ICU admission with full-code management followed by reappraisal on day 6 in all nonbedridden cancer patients for whom lifespan-extending cancer treatment is available.

To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy. Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005. 547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy. This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.

Post-operative weight bearing after meniscal repair is a point of debate among physicians. This study sought to evaluate whether patients adhering to an immediate WBAT rehabilitation programme have a higher failure rate compared to those adhering to a more traditional, protected, NWB status following meniscal repair. The null hypothesis was that there would be no difference in failure between the two groups. A retrospective review of meniscal repair patients greater than 5 years from surgery was performed for patients receiving meniscal repair treatment. Patients were categorized by post-surgical weight-bearing status, either NWB or WBAT, and then analysed for failure of repair. Failure was defined as re-operation on the torn meniscus. The study controlled for variables including age at surgery, sex, height, weight, and BMI, classification of tear type, acuity of the tear, repair location (medial or lateral), repair location within the meniscus, repair technique, and concomitant procedures. Re-operations were performed in 61 of 157 patients [38.9%]. There was no difference between weight-bearing groups for failure of meniscus repair (n.s.). The tears were acute vertical tears located in the posterior horn and body. For the 61 patients with re-operation, the average time to re-operation was 2.2 years with 10 [16%] > 5 years from surgery, 17 [28%] 2-5 years from surgery, and 34 [56%] bearing groups for rate of re-operation (n.s.). Weight bearing as tolerated after meniscal repair for peripheral, vertical tears does not result in a higher failure rate than traditional, non-weight bearing over a five-year follow-up period. The clinical relevance is that, based on these data, it may be appropriate to allow weight bearing as tolerated following meniscal repair of peripheral, vertical tears.

Background. The need for psychosocial support in cancer patients is estimated in the literature at 14-50%. At the Department of Radiation Oncology, Medical University of Vienna, approximately 3,000 patients are seen annually. Due to limited staff resources, highly distressed patients need to be selected for focused support. A multidisciplinary screening questionnaire covering physical, social and psychological problems and needs was successfully implemented in clinical routine. We present the results of a representative sample of 1,500 heterogeneous cancer patients before beginning radiotherapy. Patients and methods. The prevalence rates of physical, social and psychological problems and needs were evaluated. Independent risk factors for critical psychological distress were analyzed in a multivariate logistic regression model, in order to identify vulnerable subgroups for focused psychosocial support. Results. Critical psychological distress was found in 22% of the overall cohort, of whom only 26% reported a need for psychological information. Clinically relevant pain was suffered by 31%. Patients' most frequent complaints were weakness, sleeping difficulties and exhaustion. Consequently, 40% were impaired in activities and 35% reported a requirement for support in daily life. A need for further information was expressed by 37% of patients. Significant risk factors for critical psychological distress included pain, functional status, support requirements and patient-reported symptoms. Differences in tumor type, metastases and sociodemographic variables had no impact on critical psychological distress. Conclusion. Approximately one third of all patients beginning radiotherapy have physical, social and psychological problems and should receive focused psychosocial support. Multivariate analysis reveals that patients with impaired ''physical integrity'' are at a significantly higher risk of experiencing critical psychological distress. (orig.)

The authors retrospectively analyzed early and late results of surgical treatment for 79 Marfan patients with aneurysms and dissection of the proximal aorta. From September 1979 to February 1996, 79 patients with Marfan syndrome underwent aortic root replacement using composite grafts (n=68, Bentall-technique 63, button-technique 5), and ascending aortic replacement with a valve-sparing procedure (n=11). There were 12 patients (15.2%) who simultaneously received partial or total arch replacement. 55 patients (69.6%) were male, and 24 female (30.4%). The average age was 33.8 years. Forty-one patient (51.9%) had non-dissecting aneurysms while the remaining 38 patients suffered from either acute (24.0%) or chronic aortic dissection (24.0%). The aortic valve was involved in 97.5% of all cases. The total early mortality (valve-sparing operation and in those with chronic aortic dissection. The follow-up rate was 98.7%. During a mean follow-up of 68+/-25 months 10 patients (13.3%) died and cardiac complications were a common cause of the late deaths. There was no late mortality in the valve-sparing operations during a mean follow-up period of 8+/-6 months, however, 1 required valve replacement. 19 (25.3%) of the 75 patients surviving late have undergone 25 secondary operations on the cardiovascular system. Reoperations at aortic sites distant from the original were much more frequent after primary repair for acute and chronic dissection when compared to non-dissecting aneurysms (pMarfan-patients with non-dissecting and dissecting aneurysms of the aortic root. Our early experience in 11 patients with valve-sparing procedures indicated that this,variant may be the better choice in selected patients.

Assessing decision quality in patient-centred care requires a preference-sensitive measure

A theory-based instrument for measuring the quality of decisions made using any form of decision technology, including both decision-aided and unaided clinical consultations is required to enable person- and patient-centred care and to respond positively to individual heterogeneity in the value...... aspects of decision making. Current instruments using the term 'decision quality' have adopted a decision- and thus condition-specific approach. We argue that patient-centred care requires decision quality to be regarded as both preference-sensitive across multiple relevant criteria and generic across all...

Cavity Shaving plus Lumpectomy versus Lumpectomy Alone for Patients with Breast Cancer Undergoing Breast-Conserving Surgery: A Systematic Review and Meta-Analysis.

Directory of Open Access Journals (Sweden)

Ke Wang

Full Text Available The margin status is a well-established prognostic predictor for patients undergoing breast-conserving surgery (BCS. Recent data suggested that cavity shaving in addition to lumpectomy might be a promising approach for improving the clinical outcomes. We aimed to compare the efficacy and safety between cavity shaving plus lumpectomy and lumpectomy alone with a systematic review and meta-analysis. We searched the PubMed, Embase, and Cochrane CENTRAL databases for studies comparing cavity shaving with lumpectomy before June 10, 2016. Both comparative studies and self-control studies were included. A random-effects model was used to estimate the odds ratios (ORs for positive margin rate, reoperation rate, recurrence rate, and weighted mean difference (WMD for excised tissue volume. Twenty-six studies were included in the meta-analysis. The cavity shaving group had a significantly lower positive margin rate than the BCS-alone group (16.4% vs. 31.9%; OR = 0.41, 95% CI 0.32-0.53, P < 0.05. Cavity shaving was associated with a significantly decreased rate of reoperation (OR = 0.42, 95% CI 0.30-0.59, P < 0.05. The overall locoregional rate was low for cavity shaving and BCS-alone (3% vs. 4%. Cavity shaving had no significant effect on the risk of locoregional recurrence (OR = 0.86, 95% CI 0.32-2.35; P = 0.78. The excised tissue volume did not differ substantially between cavity shaving and BCS alone (WMD = -23.88, 95% CI -55.20 to 7.44, P = 0.14. For patients undergoing BCS, additional cavity shaving was an effective method to decrease the positive margin rate and avoid reoperation. The addition of cavity shaving did not appear to have excessive excised tissue volume compared with partial mastectomy alone.

Peptic ulcer perforation (PUP) is a very serious condition that leads to excessive complications and mortality. This study aimed to explore the possible prognostic factors and complications in patients with perforated peptic ulcer operation. A 6-year retrospective cohort study in Nakornping Hospital between January 1, 2005 and December 31, 2010 was conducted. The study included 912 patients who underwent PUP surgery. Patient characteristics were analyzed by using frequency, percentage, mean (standard deviation) and median (range). A comparison between groups was made. The Pearson's Chi-squared or Fisher's exact test was used for categorical variables, as appropriate. The Student's t test was used for continuous variables with normal distribution, and Wilcoxon rank sum test was performed for continuous variables with non-normal distributions. Exponential risk regression analysis was performed to estimate the relative risk (RR) for the prognostic factors with a probability value of 3 h (RR: 9.83; 95% CI: 1.61-59.66); unplanned admission to ICU (RR: 9.22; 95% CI: 1.55 - 54.68); and prolonged ventilation > 24 h (RR: 9.02; 95% CI: 0.42 - 9.98) were associated with post-operative PUP complications. Post-operative complications developed in 87 (9.54%) patients with 135 complications: 11 (1.21%) patients underwent re-operation, 32 (3.51%) patients suffered with surgical site infection, 74 (8.11%) patients encountered with pneumonia and 18 (1.97%) patients died. Post-operative complications including surgical site infection (incidence rate ratio (IRR): 2.00; 95% CI: 0.76 - 5.27), re-operation (IRR: 2.65; 95% CI: 0.73 - 9.62) and pneumonia (IRR: 6.97; 95% CI: 6.30 - 7.70) tend to be associated with mortality. The risk ratio showed a trend towards an increased risk for post-operative mortality with smaller values. However, this trend was not statistically significant. The findings might have clinical importance as to optimize the surgical management of PUP and to minimize the

Comparing nutritional requirements, provision and intakes among patients prescribed therapeutic diets in hospital: An observational study.

Rattray, Megan; Desbrow, Ben; Roberts, Shelley

Nutrition is an important part of recovery for hospitalized patients. The aim of this study was to assess the nutritional adequacy of meals provided to and consumed by patients prescribed a therapeutic diet. Patients (N = 110) prescribed a therapeutic diet (texture-modified, low-fiber, oral fluid, or food allergy or intolerance diets) for medical or nutritional reasons were recruited from six wards of a tertiary hospital. Complete (24-h) dietary provisions and intakes were directly observed and analyzed for energy (kJ) and protein (g) content. A chart audit gathered demographic, clinical, and nutrition-related information to calculate each patient's disease-specific estimated energy and protein requirements. Provisions and intake were considered adequate if they met ≥75% of the patient's estimated requirements. Mean energy and protein provided to patients (5844 ± 2319 kJ, 53 ± 30 g) were significantly lower than their mean estimated requirements (8786 ± 1641 kJ, 86 ± 18 g). Consequently, mean nutrition intake (4088 ± 2423 kJ, 37 ± 28 g) were significantly lower than estimated requirements. Only 37% (41) of patients were provided with and 18% (20) consumed adequate nutrition to meet their estimated requirements. No therapeutic diet provided adequate food to meet the energy and protein requirements of all recipients. Patients on oral fluid diets had the highest estimated requirements (9497 ± 1455 kJ, 93 ± 16 g) and the lowest nutrient provision (3497 ± 1388 kJ, 25 ± 19 g) and intake (2156 ± 1394 kJ, 14 ± 14 g). Hospitalized patients prescribed therapeutic diets (particularly fluid-only diets) are at risk for malnutrition. Further research is required to determine the most effective strategies to improve nutritional provision and intake among patients prescribed therapeutic diets. Copyright © 2017 Elsevier Inc.

To compare the 1-year results after aortic valve-sparing (AVS) or valve-replacing (AVR) aortic root replacement from a prospective, international registry of 316 patients with Marfan syndrome (MFS). Patients underwent AVS (n = 239, 76%) or AVR (n = 77, 24%) aortic root replacement at 19 participating centers from 2005 to 2010. One-year follow-up data were complete for 312 patients (99%), with imaging findings available for 293 (94%). The time-to-events were compared between groups using Kaplan-Meier curves and Cox proportional hazards models. Two patients (0.6%)--1 in each group--died within 30 days. No significant differences were found in early major adverse valve-related events (MAVRE; P = .6). Two AVS patients required early reoperation for coronary artery complications. The 1-year survival rates were similar in the AVR (97%) and AVS (98%) groups; the procedure type was not significantly associated with any valve-related events. At 1 year and beyond, aortic regurgitation of at least moderate severity (≥2+) was present in 16 patients in the AVS group (7%) but in no patients in the AVR group (P = .02). One AVS patient required late AVR. AVS aortic root replacement was not associated with greater 30-day mortality or morbidity rates than AVR root replacement. At 1 year, no differences were found in survival, valve-related morbidity, or MAVRE between the AVS and AVR groups. Of concern, 7% of AVS patients developed grade ≥2+ aortic regurgitation, emphasizing the importance of 5 to 10 years of follow-up to learn the long-term durability of AVS versus AVR root replacement in patients with MFS.

Steroid-induced hyperglycemia is common in hospitalized patients with diabetes mellitus. Guidelines for glucose management in this setting are lacking. We conducted a retrospective chart review of non-critically ill patients with diabetes receiving steroids, hospitalized from January 2009 to October 2012. Fifty-eight patients were identified from 247 consults. Multivariable linear regression was used to assess median daily insulin requirements of normoglycemic patients compared with hyperglycemic patients. Of the 58 total patients included in our study, 20 achieved normoglycemia during admission (patient-day weighted mean blood glucose [PDWMBG] level = 154 ± 16 mg/dL) and 38 remained hyperglycemic (PDWMBG level = 243 ± 39 mg/dL; P < 0.001). There were no differences between the 2 patient groups in age, sex, race, body weight, renal function, HbA1c level, glucose-altering medications, diabetes type, or disease duration. Following multivariable adjustment, compared with hyperglycemic patients, normoglycemic patients required similar units of basal insulin (median interquartile range [IQR])(23.6 [17.9, 31.2] vs 20.1 [16.5, 24.4]; P = 0.35); higher units of nutritional insulin (45.5 [34.2, 60.4] vs 20.1 [16.4, 24.5]; P < 0.001]; and lower units of correctional insulin (5.8 [4.1, 8.1] vs 13.0 [10.2, 16.5]; P < 0.001]). Patients achieving normoglycemia required a significantly lower percentage of correction insulin (total daily dose [TDD]: 7.4% vs 23.4%; P < 0.001) and a higher percentage of nutritional insulin (TDD: 58.1% vs 36.2%; P <0.001) than hyperglycemic patients. There was no difference in the TDD per kilogram, TDD per milligram hydrocortisone dose, or TDD per milligram hydrocortisone dose per kilogram weight between the 2 groups. The data suggest that non-critically ill patients with hyperglycemia receiving steroids require a higher percentage of TDD insulin therapy as nutritional insulin to achieve normoglycemia.

Multi-institutional retrospective case series of 8887 patients who underwent anterior cervical spine surgery. Anterior decompression from discectomy or corpectomy is not without risk. Surgical morbidity ranges from 9% to 20% and is likely underreported. Little is known of the incidence and effects of rare complications on functional outcomes following anterior spinal surgery. In this retrospective review, we examined implant extrusions (IEs) following anterior cervical fusion. A retrospective multicenter case series study involving 21 high-volume surgical centers from the AOSpine North America Clinical Research Network. Medical records for 17 625 patients who received cervical spine surgery (levels from C2 to C7) between January 1, 2005, and December 31, 2011, were reviewed to identify occurrence of 21 predefined treatment complications. Following anterior cervical fusion, the incidence of IE ranged from 0.0% to 0.8% across 21 institutions with 11 cases reported. All surgeries involved multiple levels, and 7/11 (64%) involved either multilevel corpectomies or hybrid constructs with at least one adjacent discectomy to a corpectomy. In 7/11 (64%) patients, constructs ended with reconstruction or stabilization at C7. Nine patients required surgery for repair and stabilization following IE. Average length of hospital stay after IE was 5.2 days. Only 2 (18%) had residual deficits after reoperation. IE is a very rare complication after anterior cervical spine surgery often requiring revision. Constructs requiring multilevel reconstruction, especially at the cervicothoracic junction, have a higher risk for failure, and surgeons should proceed with caution in using an anterior-only approach in these demanding cases. Surgeons can expect most patients to regain function after reoperation.

In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment. Different treatment protocols are used by two similar Swedish regional emergency care hospitals. Dynamic hip screw is used for fractures considered as stable within the respective treatment protocol, whereas one treatment protocol (Medoff sliding plate/dynamic hip screw) uses biaxial Medoff sliding plate for unstable pertrochanteric fractures and uniaxial Medoff sliding plate for subtrochanteric fractures, the second (intramedullary nail/dynamic hip screw) uses intramedullary nail for subtrochanteric fractures and for pertrochanteric fractures with intertrochanteric comminution or subtrochanteric extension. All orthopedic surgeries are registered in a regional database. All consecutive trochanteric fracture operations during 2011-2012 (n = 856) and subsequent technical reoperations (n = 40) were derived from the database. Reoperations were analysed and classified into the categories adjustment (percutaneous removal of the locking screw of the Medoff sliding plate or the intramedullary nail, followed by fracture healing) or minor, intermediate (reosteosynthesis) or major (hip joint replacement, Girdlestone or persistent nonunion) technical complications. The relative risk of intermediate or major technical complications was 4.2 (1.2-14) times higher in unstable pertrochanteric fractures and 4.6 (1.1-19) times higher in subtrochanteric fractures with treatment protocol: intramedullary nail/dynamic hip screw, compared to treatment protocol: Medoff sliding plate/dynamic hip screw. Overall rates of intermediate and major technical complications in unstable pertrochanteric and subtrochanteric fractures were with biaxial Medoff sliding plate 0.68%, with uniaxial Medoff sliding plate 1.4%, with dynamic hip screw 3.4% and with intramedullary nail 7.2%.

This article provides a summary of currently available information from a broad range of disciplines aimed at guiding the physician caring for the pregnant patient who requires nonobstetric surgery. An understanding of the anatomic and physiologic alterations that occur during pregnancy will allow such procedures to be accomplished with morbidity and mortality approaching those of nonpregnant surgical patients. The presence of the fetus does impose some restraint; however, this should rarely impair appropriate diagnosis and treatment of maternal disease. This obtains from the broad range of diagnostic and therapeutic alternatives available, and from the fact that what is beneficial for maternal health is generally best for the fetus. 64 references

Background Dysfunction of mechanical heart valve prostheses is an unusual but potentially lethal complication after mechanical prosthetic valve replacement. We seek to report our experience with mechanical valve dysfunction regarding etiology, surgical techniques and early outcomes. Methods Clinical data of 48 patients with mechanical valve dysfunction surgically treated between October 1996 and June 2011 were analyzed. Results Mean age was 43.7±10.9 years and 34 were female (70.8%). The median interval from primary valve implantation to dysfunction was 44.5 months (range, 1 hour to 20 years). There were 21 emergent and 27 elective reoperations. The etiology was thrombosis in 19 cases (39.6%), pannus in 12 (25%), thrombosis and pannus in 11 (22.9%), improper disc orientation in 2 (4.1%), missing leaflet in 1 (2.1%), excessively long knot end in 1 (2.1%), endogenous factor in 1 (2.1%) and unidentified in 1 (2.1%). Surgical procedure was mechanical valve replacement in 37 cases (77.1%), bioprosthetic valve replacement in 7 (14.9%), disc rotation in 2 (4.2%) and excision of excessive knot end in 1 (2.1%). Early deaths occurred in 7 patients (14.6%), due to low cardiac output in 3 (6.3%), multi-organ failure in 2 (4.2%) and refractory ventricular fibrillation in 2 (4.2%). Complications occurred in 10 patients (20.8%). Conclusions Surgical management of mechanical valve dysfunction is associated with significant mortality and morbidity. Earlier identification and prompt reoperation are vital to achieving better clinical outcomes. The high incidence of thrombosis in this series highlights the need for adequate anticoagulation and regular follow-up after mechanical valve replacement. PMID:26793354

This retrospective study of medical records, surgical protocols, patient observation cards, and imaging files of 100 patients treated for subdural hematoma analyzed the type of hematoma, patient age and sex, operative technique, neurological status, cause of injury, duration of hospital stay, mortality rate, and the number of and reasons for reoperations to determine the effects on treatment outcomes. The time between the head injury and onset of neurological symptoms was analyzed versus the type of hematoma determined from computed tomography (CT) scans. Acute hematomas accounted for 38% of the cases, with subacute hematomas representing 20%, and chronic ones accounting for 42%. In trauma patients, the mean time interval between the injury and onset of neurological symptoms was 0.38 days for acute hematomas, 13.8 days for subacute hematomas, and 23.75 days for chronic hematomas. Repeat surgery was carried out in 26% of the cases. Improvement was obtained in 44% of cases, deterioration in 20%, and no change in neurological status in 36%. Timing of the operations was between 15:00 and 23:00 in 45%, between 23:00 and 7:00 in 33%, and between 7:00 and 15:00 in 22%. The classification of hematomas based on CT presentation corresponds to the classification based on the time elapsed between injury and onset of symptoms, and appears to be appropriate and useful in everyday practice. No preceding injury was identified in 31.6% of acute hematomas, 50% of subacute hematomas, and 61.9% of chronic hematomas. Analysis of reoperations indicates that trepanation may be superior to craniotomy as primary surgery for subacute and chronic hematomas. Subdural hematoma surgeries take place at all times of the day, with most carried out outside the usual working hours.

Over the past decade, osteochondral allograft transplantation has soared in popularity. Advances in storage techniques have demonstrated improved chondrocyte viability at longer intervals and allowed for potential of increased graft availability. Recent studies have stratified outcomes according to location and etiology of the chondral or osteochondral defect. Unipolar lesions generally have favorable outcomes with promising 10-year survival rates. Though those undergoing osteochondral allograft transplantation often require reoperation, patient satisfaction remains high.

Blood transfusion has well-documented adverse effects. As part of a blood conservation initiative at our center, we began routine use of cell saver for all congenital heart surgery performed on cardiopulmonary bypass since 2014. This study aimed to compare transfusion rates prior to, and in the first and second year after this initiative. We hypothesized that cell saver use would decrease transfusion requirements in second year after use of the cell saver compared to the pre cell saver group. Consecutive patients under 18 years undergoing congenital heart surgery on cardiopulmonary bypass were retrospectively analyzed as 3 one-year cohorts defined above. We excluded patients who required mechanical support or reoperation at index admission. Baseline characteristics, and use of blood intraoperatively and postoperatively were compared between groups. The 3 groups had similar baseline characteristics. Blood use was significantly lower in year 2 after cell saver initiation as compared to the pre cell saver group both intra- and postoperatively. The median difference in volume of intraoperative blood transfusion was lower by 138 mL/m 2 (-266, -10 mL/m 2 ) in year 2 when compared to the pre cell saver group. Similarly, the proportion of subjects requiring red blood cell transfusion postoperatively on day of surgery was lower by 10% (-15%, -6%). Standardized use of cell saver significantly decreased perioperative blood use in children undergoing cardiac surgery at our center. A risk-adjusted transfusion threshold for children undergoing heart surgery needs to be developed to further decrease exposure to blood products and associated costs. © 2018 John Wiley & Sons Ltd.

Temporary abdominal closure with zipper-mesh device for management of intra-abdominal sepsis

Directory of Open Access Journals (Sweden)

Edivaldo Massazo Utiyama

Full Text Available OBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years; 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

A best evidence topic was written according to a structured protocol. The clinical question investigated was: is low serum albumin associated with postoperative complications in patients undergoing cardiac surgery? There were 62 papers retrieved using the reported search strategy. Of these, 12 publications embodied the best evidence to answer this clinical question. The authors, journal, date and country of the publication, patient group investigated, study design, relevant outcomes and results of these papers were tabulated. This paper includes a total of 12 589 patients, and of the papers reviewed, 4 were level 3 and 8 level 4. Each of the publications reviewed and compared either all or some of the following postoperative complications: mortality, postoperative bleeding requiring reoperation, prolonged hospital stay and ventilatory support, infection, liver dysfunction, delirium and acute kidney injury (AKI). Of the studies that examined postoperative mortality, all except for three established a significant multivariate association with low preoperative albumin level. Some scepticism is required in accepting other results that were only present in univariate analysis. While three studies examined multiple levels of serum albumin, most dichotomized the serum albumin levels into normal and abnormal groups. This led to differing classifications of hypoalbuminaemia, ranging from less than 2.5 to 4.0 g/dl. The available evidence, however, suggests that low preoperative serum albumin level in patients undergoing cardiac surgery is associated with the following: (i) increased risk of mortality after surgery and (ii) greater incidence of postoperative morbidity. While the evidence supports the use of preoperative albumin in assessing post-cardiac surgery complications, a specific level of albumin considered to be abnormal cannot be concluded from this review. © The Author 2015.

Anticoagulation with warfarin affects approximately 140,000 post-cardiac surgery patients every year, yet there remains limited published data in this patient population. Dosing remains highly variable due to intrinsic risk factors that plague cardiac surgery candidates and a lack of diverse literature that can be applied to those who have undergone a cardiac surgery alternative to heart valve replacement (HVR). In the present study, our aim was to compare the warfarin requirements between HVR and non-HVR patients. This was a single-center, retrospective study of post-cardiac surgery patients initiated on warfarin at Mayo Clinic Hospital, Rochester, from January 1st, 2013 to October 31st, 2016. The primary outcome was the maintenance warfarin dose at the earliest of discharge or warfarin day 10 between patients with HVR and non-HVR cardiac surgeries. A total of 683 patients were assessed during the study period: 408 in the HVR group and 275 in the non-HVR group. The mean warfarin maintenance doses in the HVR and non-HVR groups were 2.55 mg [standard deviation (SD) 1.52] and 2.43 mg (SD 1.21), respectively (adjusted p = 0.65). A multivariable analysis was performed to adjust for gender, age, body mass index and drug interactions. This was the largest study to evaluate warfarin dose requirements in post-cardiac surgery patients and is the first to compare warfarin requirements between HVR and non-HVR patients during the immediate post-operative period. Both groups had similar warfarin requirements, which supports expanding the initial warfarin dosing recommendations of the 9th edition Chest guideline to include non-HVR patients as well as HVR patients.

Renal cell carcinoma (RCC) with cavoatrial extension is a rare and complex problem. Complete resection is difficult but correlates with favorable patient outcomes. We present 2 cases of successful reoperative resections of recurrent RCC in patients with level III-IV cavoatrial involvement. We used a thoracoabdominal approach, peripheral cannulation, and hypothermic circulatory arrest. We advocate this novel approach as a successful means of avoiding a more difficult reoperation.

Chen, Stephanie; Jarboe, Marcus D; Teitelbaum, Daniel H

2012-03-01

Although laparoscopic Nissen fundoplication is the standard surgical treatment for gastroesophageal reflux disease (GERD), surgical complications and post-operative pain are not uncommon, especially for those patients who are neurologically impaired (NI) or undergoing re-operative procedures. To address this challenge, we utilized the transoral incisionless fundoplication (TIF) procedure to treat GERD via an endoscopic approach. Eleven TIF patients were included with an average age of 16.5 ± 5.1 years and weight of 45.7 ± 13.3 kg. NI was present in nine patients (82%), including a predominant number of patients with a history of seizures and gastrostomy tube feeding. Five patients had a history of a previous failed fundoplication requiring a re-operative procedure (45%). A retrospective chart review evaluated patient outcomes and post-operative complications. The length of the TIF procedure was 113.3 ± 31.3 min with minimal blood loss. The length of stay was 1.2 ± 0.4 days, although one TIF patient was re-admitted for endoscopic clipping for gastric bleeding. At a follow-up of 8.2 ± 4.2 months, TIF effectively resolved GERD in 10 out of 11 children. A few of the patient's families reported complaints of gagging or dysphagia (30%, 3/11); however it was difficult to determine if complaints were due the procedures itself or baseline NI. All patients who had a follow-up upper GI or pH probe study showed no evidence of reflux. One TIF patient had no recurrent reflux but required an esophago-gastric disconnection for retching. The TIF procedure can complement the current surgically and medically available options for children with GERD, especially in complicated patients such as those with NI. However, complications including hemorrhage emphasize the potential risk of the procedure. Further studies with more patients and a longer follow-up course must be conducted to better assess efficacy.

Oral vitamin C supplementation reduces erythropoietin requirement in hemodialysis patients with functional iron deficiency.

Sultana, Tanjim; DeVita, Maria V; Michelis, Michael F

2016-09-01

Functional iron deficiency (FID) is a major cause of persistent anemia in dialysis patients and also contributes to a suboptimal response to erythropoietin (Epo) administration. Vitamin C acts as an enzyme cofactor and enhances mobilization of the ferrous form of iron to transferrin thus increasing its bioavailability. High-dose intravenous vitamin C has been shown to decrease the Epo requirement and improve hemoglobin levels in previous studies. This study assessed the effect of low-dose oral vitamin C on possible reduction in Epo dose requirements in stable hemodialysis patients with FID. This prospective study included 22 stable hemodialysis patients with FID defined as transferrin saturation (T sat) 100 mcg/L with Epo requirement of ≥4000 U/HD session. Patients received oral vitamin C 250 mg daily for 3 months. Hemoglobin, iron and T sat levels were recorded monthly. No one received iron supplementation during the study period. There was a significant reduction in median Epo dose requirement in the 15 patients who completed the study, from 203.1 U/kg/week (95 % CI 188.4-270.6) to 172.8 U/kg/week (95 % CI 160.2-214.8), (P = 0.01). In the seven responders, there was 33 % reduction in Epo dose from their baseline. Despite adjustment of Epo dose, the mean hemoglobin level was significantly increased from 10.1 ± 0.6 to 10.7 ± 0.6 mg/dL (P = 0.03). No adverse effects of oral vitamin C were observed. Daily low-dose oral vitamin C supplementation reduced Epo dose requirements in hemodialysis patients with FID. Limitations of this study include a small sample size and the lack of measurements of vitamin C and oxalate levels. Despite concerns regarding oral vitamin C absorption in dialysis patients, this study indicates vitamin C was well tolerated by all participants without reported adverse effect.

What does respect for the patient's autonomy require?

Science.gov (United States)

Cheng, Kam-Yuen

2013-11-01

Personal autonomy presupposes the notion of rationality. What is not so clear is whether, and how, a compromise of rationality to various degrees will diminish a person's autonomy. In bioethical literature, three major types of threat to the rationality of a patient's medical decision are identified: insufficient information, irrational beliefs/desires, and influence of different framing effects. To overcome the first problem, it is suggested that patients be provided with information about their diseases and treatment choices according to the objective standard. I shall explain how this should be finessed. Regarding the negative impact of irrational beliefs/desires, some philosophers have argued that holding irrational beliefs can still be an expression of autonomy. I reject this argument because the degree of autonomy of a decision depends on the degree of rationality of the beliefs or desires on which the decision is based. Hence, to promote patient autonomy, we need to eliminate irrational beliefs by the provision of evidence and good arguments. Finally, I argue that the way to smooth out the framing effects is to present the same information in different perspectives: it is too often assumed that medical information can always be given in a complete and unadorned manner. This article concludes with a cautionary note that the protection of patient autonomy requires much more time and effort than the current practice usually allows. © 2012 John Wiley & Sons Ltd.

to evaluate functional results of reoperation performed according to the CIRCLE technology and using the VisuMax femtosecond laser and MEL-80 excimer laser in cases of regression of the refractive effect after SMILE surgery. We studied a group of post-SMILE patients. In those, who showed regression of the refractive effect at 1 year, reoperation was performed according to the CIRCLE technology and using the VisuMax femtosecond laser. The corneal flap was separated from the stromal bed and turned aside. Excimer laser ablation of the stromal bed was performed with the MEL 80 machine. The corneal flap was then placed back and rinsed from both sides. Uncorrected (UCVA) and corrected (BCVA) visual acuity as well as spherical equivalent (SE) were estimated before reoperation, on day 1, and at 1 month. After reoperation, BCVA and UCVA improved. Patient refraction became close to emmetropia. Specifically, UCVA was 0.23±0.18 at baseline (i.e. 1 year after SMILE) and 0.93±0.11 after the CIRCLE procedure (pstatistically significant - from 0.95±0.1 to 0.93±0.11 (p>0.05). Reoperation performed according to the CIRCLE technology and using the VisuMax femtosecond laser and MEL-80 excimer laser provides an increase in visual acuity in case of post-SMILE regression of the refractive effect.

The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Full Text Available Continuous renal replacement therapy (CRRT has proved to be beneficial for the treatment of critically ill patients with acute renal failure (ARF. The aim of this study is to determine the outcome and identify the predictors of mortality of critically ill patients treated with CRRT for ARF in the intensive care unit (ICU. This prospective cohort study of critically ill patients with ARF requiring CRRT admitted to the ICU was carried out at a tertiary care hospital in Saudi Arabia from 2002 to 2008. A total of 644 of 7173 patients with ARF required CRRT were studied. About 9% of the ARF patients required CRRT and comprised mainly those with medical causes, carrying a mortality of 64%. Multivariate analysis found high serum creatinine as an independent factor for better outcome and requirement of mechanical ventilation (MV as an independent factor for worse outcome. In our cohort study, ARF requiring CRRT in the ICU was associated with a high mortality.

The objective of our study was to identify the incidence and risk factors of anastomotic leaks following transhiatal esophagectomy (THE). A prospective study was conducted on 61 patients treated for carcinoma of the esophagus between 2006 and 2007. We examined the following variables: age, gender, preoperative cardiovascular function, intraoperative complications such as hypotension, arrhythmia, mediastinal manipulation period, blood loss volume, blood transfusion, duration of surgery, postoperative complications such as anastomotic leak, anastomotic stricture, requiring reoperation, respiratory complications, and total morbidity and mortality. Variables were compared between the patients with and without anastomotic leak. T-test for quantitative variables and Chi-square test for qualitative variables were used to find out any relationship. P value less than 0.05 was considered significant. Out of 61 patients, anastomotic leaks occurred in 13 (21.3%). Weight loss, forced expiratory volume (FEV1) < 2 lit, preoperative albumin, intaoperative blood loss volume, and respiratory complication were associated with the anastomotic leak in patients undergoing THE. Anastomotic leaks were the leading cause of postoperative morbidity, anastomotic stricture, and reoperation. Anastomotic leakage is a life-threatening postoperative complication. Careful attention to the factors contributing to the development of a leak can reduce the incidence of anastomotic complications postoperatively. (author)

2013-01-01

Objective To analyze the characteristics of patients who needed a blood transfusion due to epistaxis-caused anemia and to define potential risk factors. Design Retrospective cohort study. Setting A total cohort of 591 epistaxis patients, prospectively included between March 2007 and April 2008 at the ENT department of the University Hospital of Zurich, was evaluated concerning the need for blood transfusions. Methods The clinical charts and medical histories of these patients were evaluated. Main outcome measures Common parameters that increase the risk for severe anemia due to epistaxis. Results Twenty-two patients required blood transfusions due to their medical condition. 22.7% suffered from traumatic nosebleeds. Another 27.3% had a known medical condition with an increased bleeding tendency. These proportions were significantly higher than in the group of patients without need of blood transfusion. The odds ratio for receiving a blood transfusion was 14.0 in patients with hematologic disorders, 4.3 in traumatic epistaxis and 7.7 in posterior bleeders. The transfusion-dependent epistaxis patients suffered significantly more often from severe posterior nosebleeds with the need for a surgical therapeutic approach. Conclusions Patients with severe nosebleeds either from the posterior part of the nose or with known hematologic disorders or traumatic epistaxis should be closely monitored by blood parameter analyses to evaluate the indication for hemotransfusion. The acronym THREAT (Trauma, Hematologic disorder, and REAr origin of bleeding → Transfusion) helps to remember and identify the factors associated with an increased risk of receiving blood transfusion.

Corno, Antonio F.; Smith, Paul; Bezuska, Laurynas; Mimic, Branko

2018-01-01

Introduction: We reviewed our experience with decellularized porcine small intestine sub-mucosa (DPSIS) patch, recently introduced for congenital heart defects. Materials and Methods: Between 10/2011 and 04/2016 a DPSIS patch was used in 51 patients, median age 1.1 months (5 days to 14.5 years), for aortic arch reconstruction (45/51 = 88.2%) or aortic coarctation repair (6/51 = 11.8%). All medical records were retrospectively reviewed, with primary endpoints interventional procedure (balloon dilatation) or surgery (DPSIS patch replacement) due to patch-related complications. Results: In a median follow-up time of 1.5 ± 1.1 years (0.6–2.3years) in 13/51 patients (25.5%) a re-intervention, percutaneous interventional procedure (5/51 = 9.8%) or re-operation (8/51 = 15.7%) was required because of obstruction in the correspondence of the DPSIS patch used to enlarge the aortic arch/isthmus, with median max velocity flow at Doppler interrogation of 4.0 ± 0.51 m/s. Two patients required surgery after failed interventional cardiology. The mean interval between DPSIS patch implantation and re-intervention (percutaneous procedure or re-operation) was 6 months (1–17 months). While there were 3 hospital deaths (3/51 = 5.9%) not related to the patch implantation, no early or late mortality occurred for the subsequent procedure required for DPSIS patch interventional cardiology or surgery. The median max velocity flow at Doppler interrogation through the aortic arch/isthmus for the patients who did not require interventional procedure or surgery was 1.7 ± 0.57 m/s. Conclusions: High incidence of re-interventions with DPSIS patch for aortic arch and/or coarctation forced us to use alternative materials (homografts and decellularized gluteraldehyde preserved bovine pericardial matrix).

To determine if postoperative urinary retention and urinary tract infections (UTIs) were predictors of future mesh complications requiring surgical intervention after midurethral sling (MUS). Administrative data in Ontario, Canada, between 2002 and 2013 were used to identify all women who underwent a mesh-based MUS. The primary outcome was revision of the transvaginal mesh sling (including mesh removal/erosion/fistula, or urethrolysis). Two potential risk factors were analyzed: postoperative retention (within 30 days of procedure) and number of postoperative emergency room visits or hospital admissions for UTI symptoms. A total of 59,556 women had a MUS, of which 1598 (2.7%) required revision surgery. Of the 2025 women who presented to the emergency room or were admitted to hospital for postoperative retention, 212 (10.5%) required operative mesh revision. Of the 11,747 patients who had at least one postoperative UTI, 366 (3.1%) patients required operative mesh revision. In adjusted analysis, postoperative retention was significantly predictive of future reoperation (hazard ratio [HR] 3.46, 95% confidence interval [CI] 2.97-4.02), and this difference persisted when urethrolysis was excluded as a reason for sling revision (HR 3.08, 95% CI 2.62-3.63). Similarly, in adjusted analysis, each additional postoperative hospital visit for UTI symptoms increased the risk for surgical intervention for mesh complications (HR 1.74, 95% CI 1.61-1.87). Postoperative urinary retention and hospital presentation for UTI symptoms are associated with an increased risk of reoperation for MUS complications. These patients should be followed and investigated for mesh complications when appropriate. Copyright © 2016 Elsevier Inc. All rights reserved.

Purpose: Radiotherapy brings a tumor patient into a special life situation in which different variables play a role of often unknown importance. The goal of this study was to investigate disease specific stress of tumor patients at the beginning of radiotherapy with established psychodiagnostic questionnaires and to evaluate the effect on psychosocial support requirement in order to reduce stress and to improve quality of life and compliance during radiotherapeutical treatment. Patients and Methods: 732 patients were screened, of whom 446 (60.9%) fulfilled the criteria for inclusion (refusals 21.0%, low Karnofsky performance status 6.6%, management problems 3.4%, language barriers 3.0%, cognitive restrictions 2.6%, death 2.5%). Disease specific aspects of stress in the questionnaire (Fragebogen zur Belastung von Krebspatienten, FBK), life situation (LS) and self-defined care requirements (BB) were self-rated by patients with different tumor types before radiotherapy. Medical and sociodemographic data were also documented. We investigated 446 patients (262 male, 184 female; median age 60.0 years) with different diagnoses. Results: Stress was observed mainly due to reduction of efficiency, anxiety and pain on the subscales. Women had a significant higher stress on subscales of pain (p=0.016) and anxiety (p=0.009), patients younger than 45 years in the subscale information (p=0.002) and patients older than 45 and younger than 60 years in the subscale anxiety (p=0.002) and the total score (p=0.003). Patients with mamma carcinoma had the highest stress. The maximum percentages of patients under high stress were found for the subscales of efficiency (43%) and anxiety (40%). The support requirement was characterized by the need of more medical information and dialogue with the doctor. We saw a significant correlation of high stress and high care requirement. Conclusions: Psychosocial support should be founded on psychosocial stress diagnostic and self-defined care

Full Text Available Objectives: 1. To study transfusion requirements in the Department of Gastroenterology of a Tertiary Referral Hospital, and their evolution over the last seven years. 2. To analyze risk factors associated with greater erythrocyte transfusion requirements. Patients and methods: erythrocyte transfusion requirements were compared for patients admitted to the Department of Gastroenterology at Hospital Virgen del Rocío, Seville, from 1999 to 2005. Clinical data of interest have been analyzed in order to determine factors associated with greater transfusion requirements. Results: 1,611 patients with a mean age of 60.45 years (59.7-61.2 were included in this study; 76.41% were males. Gastric ulcers were the cause of bleeding in 18.4% of cases (with 69% requiring transfusions; duodenal ulcers caused 22.2% of cases (with 52.9% requiring transfusions, and portal hypertension caused 33.6% of cases (with 90.2% requiring transfusions. Upper and lower gastrointestinal bleeding of unknown origin requires transfusions in 88.9 and 96.2% of cases, respectively. A multivariate logistic regression analysis showed that clinical presentations such as hematemesis (odds ratio = 3.12, hematochezia (odds ratio = 33.17, gastrointestinal hemorrhage of unknown origin (odds ratio = 6.57, and hemorrhage as a result of portal hypertension (odds ratio = 3.43 were associated with greater transfusion requirements for erythrocyte concentrates. No significant differences were observed between the percentages of patients who received transfusions from 1999 to 2005. Conclusions: 1. No differences have been observed between the percentages of patients who received transfusions over the last seven years at our Department of Gastroenterology. 2. Patients presenting with hematemesis or hematochezia, in addition to those with bleeding of unknown origin or from portal hypertension, are prone to have greater transfusion requirements.

Valve repair for aortic insufficiency requires a tailored surgical approach determined by the leaflet and aortic disease. Over the past decade, we have developed a functional classification of AI, which guides repair strategy and can predict outcome. In this study, we analyze our experience with a systematic approach to aortic valve repair. From 1996 to 2007, 264 patients underwent elective aortic valve repair for aortic insufficiency (mean age - 54 +/- 16 years; 79% male). AV was tricuspid in 171 patients bicuspid in 90 and quadricuspid in 3. One hundred fifty three patients had type I dysfunction (aortic dilatation), 134 had type II (cusp prolapse), and 40 had type III (restrictive). Thirty six percent (96/264) of the patients had more than one identified mechanism. In-hospital mortality was 1.1% (3/264). Six patients experienced early repair failure; 3 underwent re-repair. Functional classification predicted the necessary repair techniques in 82-100% of patients, with adjunctive techniques being employed in up to 35% of patients. Mid-term follow up (median [interquartile range]: 47 [29-73] months) revealed a late mortality rate of 4.2% (11/261, 10 cardiac). Five year overall survival was 95 +/- 3%. Ten patients underwent aortic valve reoperation (1 re-repair). Freedoms from recurrent Al (>2+) and from AV reoperation at 5 years was 88 +/- 3% and 92 +/- 4% respectively and patients with type I (82 +/- 9%; 93 +/- 5%) or II (95 +/- 5%; 94 +/- 6%) had better outcomes compared to type III (76 +/- 17%; 84 +/- 13%). Aortic valve repair is an acceptable therapeutic option for patients with aortic insufficiency. This functional classification allows a systematic approach to the repair of Al and can help to predict the surgical techniques required as well as the durability of repair. Restrictive cusp motion (type III), due to fibrosis or calcification, is an important predictor for recurrent Al following AV repair.

Robotic technology is increasingly adopted in urologic surgery and a variety of techniques has been described for minimally invasive treatment of upper tract urothelial cancer (UTUC). To describe a simplified surgical technique of robot-assisted nephroureterectomy (RANU) and to report our single-center surgical outcomes. Patients with history of UTUC treated with this modality between April 2010 and August 2013 were included in the analysis. Institutional review board approval was obtained. Informed consent was signed by all patients. A simplified single-step RANU not requiring repositioning or robot redocking. Lymph node dissection was performed selectively. Descriptive analysis of patients' characteristics, perioperative outcomes, histopathology, and short-term follow-up data was performed. The analysis included 31 patients (mean age: 72.4±10.6 yr; mean body mass index: 26.6±5.1kg/m(2)). Twenty-six of 30 tumors (86%) were high grade. Mean tumor size was 3.1±1.8cm. Of the 31 patients, 13 (42%) had pT3 stage disease. One periureteric positive margin was noted in a patient with bulky T3 disease. The mean number of lymph nodes removed was 9.4 (standard deviation: 5.6; range: 3-21). Two of 14 patients (14%) had positive lymph nodes on final histology. No patients required a blood transfusion. Six patients experienced complications postoperatively, with only one being a high grade (Clavien 3b) complication. Median hospital stay was 5 d. Within the follow-up period, seven patients experienced bladder recurrences and four patients developed metastatic disease. Our RANU technique eliminates the need for patient repositioning or robot redocking. This technique can be safely reproduced, with surgical outcomes comparable to other established techniques. We describe a surgical technique using the da Vinci robot for a minimally invasive treatment of patients presenting with upper tract urothelial cancer. This technique can be safely implemented with good surgical outcomes

Although chronic subdural hematoma (CSH) can be treated by surgery, little is known about age-dependent symptoms and age-adjusted rates of restoring functional integrity. To evaluate the clinical symptoms and the course of CSH in patients of different age groups (AGs), we reviewed patients with CSH treated at our department over the past 22 years. This retrospective analysis included 697 patients with CSH (461 men, 236 women; mean age 70.1 years). Subgroup analysis was done according to AG 1) 95 years. Most patients had been treated with burr-hole trephination and implantation of a subdural drain (96.5%; n = 673). No significant difference concerning surgical morbidity and mortality was found between the AGs, but patients >75 years more frequently required reoperation (P = 0.001). Preoperatively, the most common symptoms were headache in AGs 1 and 2 (56.3% and 48.5%) and mnestic deficits in AGs 3-5 (54.9%, 51.9%, and 50.0%). After surgery, the clinical symptoms of CSH had significantly abated in all age groups. The most common clinical residuals were motor deficits in AG 1 (10.4%), mnestic deficits in AG 2 (10.7%), AG 4 (24.1%), and AG 5 (50.0%), and organic brain syndrome in AG 3 (15.0%). CSH predominantly caused unspecific symptoms such as headache and cognitive decline. CSH surgery immediately relieved symptoms in patients of all AGs. However, improvement rates significantly depended on patient age. This should be taken into consideration when advising on surgical treatment of CSH. Copyright © 2016 Elsevier Inc.

Our goal was to evaluate the operative outcomes of the frozen elephant trunk technique using the E-Vita Open Plus® hybrid prosthesis in chronic aortic arch diseases and report clinical and radiological outcomes at the 1-year follow-up. As determined from a prospective multicentre registry, 94 patients underwent frozen elephant trunk procedures using the E-Vita Open Plus hybrid device for the treatment of chronic aortic conditions, including 50% chronic aortic dissections, 40% degenerative aneurysms and 10% miscellaneous indications. Fifty percent of the cases were reoperations. The perioperative mortality rate was 11.7%. Spinal cord ischaemia and stroke rates were 4% and 9.6%, respectively. The mean cardiopulmonary bypass time was 252 ± 97 min, cardiac ischaemia time was 152 ± 53 min and cerebral perfusion time was 82 ± 22 min. Concomitant procedures were observed in 15% of patients. Among the 83 surviving patients, the survival rate after the 1-year follow-up was 98%. Eleven percent of patients underwent endovascular completion, whereas 4% of patients required aortic reintervention at 1 year. The E-Vita Open Plus hybrid device confirms the favourable short- and mid-term outcomes offered by its predecessor in frozen elephant trunk procedures in patients with chronic aortic arch disease. Implantation of the E-Vita Open Plus is associated with good 1-year survival rates, good rates of favourable aortic remodelling in both chronic dissection and degenerative aneurysms and a reproducible technique in a multicentre registry. Continued follow-up is required due to the risk of evolution at the downstream aorta. © The Author 2017.

2017-07-01

OBJECTIVE During the mini-open posterior corpectomy, percutaneous instrumentation without fusion is performed above and below the corpectomy level. In this study, the authors' goal was to compare the perioperative and long-term implant failure rates of patients who underwent nonfused percutaneous instrumentation with those of patients who underwent traditional open instrumented fusion. METHODS Adult patients who underwent posterior thoracic corpectomies with cage reconstruction between 2009 and 2014 were identified. Patients who underwent mini-open corpectomy had percutaneous instrumentation without fusion, and patients who underwent open corpectomy had instrumented fusion above and below the corpectomy site. The authors compared perioperative outcomes and rates of implant failure requiring reoperation between the open (fused) and mini-open (unfused) groups. RESULTS A total of 75 patients were identified, and 53 patients (32 open and 21 mini-open) were available for followup. The mean patient age was 52.8 years, and 56.6% of patients were male. There were no significant differences in baseline variables between the 2 groups. The overall perioperative complication rate was 15.1%, and there was no significant difference between the open and mini-open groups (18.8% vs 9.5%; p = 0.359). The mean hospital stay was 10.5 days. The open group required a significantly longer stay than the mini-open group (12.8 vs 7.1 days; p open and mini-open groups at 6 months (3.1% vs 0.0%, p = 0.413), 1 year (10.7% vs 6.2%, p = 0.620), and 2 years (18.2% vs 8.3%, p = 0.438). The overall mean follow-up was 29.2 months. CONCLUSIONS These findings suggest that percutaneous instrumentation without fusion in mini-open transpedicular corpectomies offers similar implant failure and reoperation rates as open instrumented fusion as far out as 2 years of follow-up.

The study objective was to determine whether recurrent or residual mild aortic regurgitation, which occurs after valve-sparing aortic root replacement, progresses over time. Between 2003 and 2008, 154 patients underwent Tirone David-V valve-sparing aortic root replacement; 96 patients (62%) had both 1-year (median, 12 ± 4 months) and mid-term (62 ± 22 months) transthoracic echocardiograms available for analysis. Age of patients averaged 38 ± 13 years, 71% were male, 31% had a bicuspid aortic valve, 41% had Marfan syndrome, and 51% underwent aortic valve repair, predominantly cusp free margin shortening. Forty-one patients (43%) had mild aortic regurgitation on 1-year echocardiogram. In 85% of patients (n = 35), mild aortic regurgitation remained stable on the most recent echocardiogram (median, 57 ± 20 months); progression to moderate aortic regurgitation occurred in 5 patients (12%) at a median of 28 ± 18 months and remained stable thereafter; severe aortic regurgitation developed in 1 patient, eventually requiring reoperation. Five patients (5%) had moderate aortic regurgitation at 1 year, which did not progress subsequently. Two patients (2%) had more than moderate aortic regurgitation at 1 year, and both ultimately required reoperation. Although mild aortic regurgitation occurs frequently after valve-sparing aortic root replacement, it is unlikely to progress over the next 5 years and should not be interpreted as failure of the valve-preservation concept. Further, we suggest that mild aortic regurgitation should not be considered nonstructural valve dysfunction, as the 2008 valve reporting guidelines would indicate. We need 10- to 15-year follow-up to learn the long-term clinical consequences of mild aortic regurgitation early after valve-sparing aortic root replacement.

We aimed to determine long-term disability and quality of life in patients with Guillain-Barré syndrome (GBS) who required mechanical ventilation (MV) in the acute phase. Our retrospective cohort study included 110 GBS patients admitted to an intensive care unit and requiring MV (01/1999-08/2010) in nine German tertiary academic medical centers. Outcome was determined 1 year or longer after hospital admission using the GBS disability scale, Barthel index (BI), EuroQuol-5D (EQ-5D) and Fatigue Severity Scale. Linear/multivariate regression analysis was used to analyze predicting factors for outcome. Mean time to follow up was 52.6 months. Hospital mortality was 5.5 % and long-term mortality 13.6 %. Overall 53.8 % had a favorable outcome (GBS disability score 0-1) and 73.7 % of survivors had no or mild disability (BI 90-100). In the five dimensions of the EQ-5D "mobility", "self-care", "usual activities", "pain" and "anxiety/depression" no impairments were stated by 50.6, 58.4, 36.4, 36.4 and 50.6 % of patients, respectively. A severe fatigue syndrome was present in 30.4 % of patients. Outcome was statistically significantly correlated with age, type of therapy and number of immunoglobulin courses. In GBS-patients requiring MV in the acute phase in-hospital, and long-term mortality are lower than that in previous studies, while long-term quality of life is compromised in a large fraction of patients, foremost by immobility and chronic pain. Efforts towards improved treatment approaches should address autonomic dysfunction to further reduce hospital mortality while improved rehabilitation concepts might ameliorate long-term disability.

Full Text Available AIMS: Spontaneous ruptured hepatocellular adenoma (SRHA is a rare life-threatening condition that may require surgical treatment to control hemorrhaging and also stabilize the patient. We report a series of emergency surgeries performed at our institution for this condition. METHODS: We reviewed medical records and radiology files of 28 patients (from 1989 to 2006 with a proven diagnosis of hepatocellular adenoma (HA. Three (10.7% of 28 patients had spontaneous ruptured hepatocellular adenoma, two of which were associated with intrahepatic hemorrhage while one had intraperitoneal bleeding. Two patients were female and one was male. Both female patients had a background history of oral contraceptive use. Sudden abdominal pain associated with hemodynamic instability occurred in all patients who suffered from spontaneous ruptured hepatocellular adenoma. The mean age was 41.6 years old. The preoperative assessment included liver function tests, ultrasonography and computed tomography. RESULTS: The surgical approaches were as follows: right hemihepatectomy for controlling intraperitoneal bleeding, and right extended hepatectomy and non-anatomic resection of the liver for intrahepatic hemorrhage. There were no deaths, and the postoperative complications were bile leakage and wound infection (re-operation, as well as intraperitoneal abscess (re-operation and pleural effusion. CONCLUSION: Spontaneous ruptured hepatocellular adenoma may be treated by surgery for controlling hemorrhages and stabilizing the patient, and the decision to operate depends upon both the patient's condition and the expertise of the surgical team.

The Changing Role for Tracheostomy in Patients Requiring Mechanical Ventilation.

Mahmood, Kamran; Wahidi, Momen M

2016-12-01

Tracheostomy is performed in patients who require prolonged mechanical ventilation or have upper airway instability. Percutaneous tracheostomy with Ciaglia technique is commonly used and rivals the surgical approach. Percutaneous technique is associated with decreased risk of stomal inflammation, infection, and bleeding along with reduction in health resource utilization when performed at bedside. Bronchoscopy and ultrasound guidance improve the safety of percutaneous tracheostomy. Early tracheostomy decreases the need for sedation and intensive care unit stay but may be unnecessary in some patients who can be extubated later successfully. A multidisciplinary approach to tracheostomy care leads to improved outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

Complications of treating terrible triad injury of the elbow: a systematic review.

Directory of Open Access Journals (Sweden)

Hong-wei Chen

Full Text Available Terrible triad injury of the elbow (TTIE, comprising elbow dislocation with radial head and coronoid process fracture, is notoriously challenging to treat and has typically been associated with complications and poor outcomes. The objective of this systematic review was to summarize the most recent available evidence regarding functional outcomes and complications following surgical management of TTIE.Medline, EMBASE, Cochrane Library, and Google Scholar were searched to identify relevant studies, which were included if they were retrospective or prospective in design, involved participants who had TTIE, and were published in English. Outcomes of interest were functional outcomes and complications.Sixteen studies, involving 312 patients, were included in the systematic review. Mean follow up after surgery was typically 25 to 30 months. Mean Mayo elbow performance scores ranged from 78 to 95. Mean Broberg-Morrey scores ranged from 76 to 90. Mean DASH scores ranged from 9 to 31. The proportion of patients who required reoperation due to complications ranged from 0 to 54.5% (overall  = 70/312 [22.4%]. Most of these complications were related to hardware fixation problems, joint stiffness, joint instability, and ulnar neuropathy. The most common complications that did not require reoperation were heterotopic ossification (39/312 [12.5%] patients and arthrosis (35/312 [11.2%] patients.The results of this systematic review indicate that functional outcomes after surgery for TTIE are generally satisfactory and that complications are common. Further research is warranted to determine which surgical techniques optimize functional outcomes and reduce the risk of complications.

Thrombocytopenia is the most common coagulation disorder in critically ill patients. No studies have investigated the epidemiology and clinical impact of this condition in emergency department (ED) patients. We aimed to investigate epidemiological features, incidence of bleeding, and diagnostic and therapeutic requirements of patients with thrombocytopenia admitted to the ED. We performed a retrospective observational study enrolling all patients admitted to the medical-surgical ED of the "Città della Salute e della Scienza di Torino" Hospital with a platelet count <150×10(9) PLTs/L, during four non-consecutive months. There were no exclusion criteria. The study included 1218 patients. The percentage of patients with severe (<50×10(9) PLTs/L) or very severe (<20×10(9) PLTs/L) thrombocytopenia was about 12%. Thrombocytopenia associated with liver cirrhosis was the most represented etiology. On the contrary, the most frequent cause in patients with newly recognized low platelet count was disseminated intravascular coagulation/sepsis. The incidence of bleeding and hypovolemia, as well as the need of transfusional support and mechanical, surgical or endoscopic hemostasis progressively increased with the severity of thrombocytopenia. Our results suggest that the detection of a platelet count lower than 50×10(9) PLTs/L may help to identify patients with higher bleeding risk in the ED setting. Additional studies are required to evaluate whether, in this setting, thrombocytopenia may represent an independent risk factor for bleeding episodes and increased mortality.

This paper compares five patients treated with 10-MV photons with 12 patients treated with a combination of 10-MV photons and 160-MV protons. From 1978 to 1986, 17 patients with craniopharyngioma have ben treated with surgery and radiation therapy. Comparison is made of dose distribution and does volume histograms for these patients treated with different techniques. Four of five patients treated with photons alone are disease free 4-13 years after treatment and one died of recurrent tumor at 6 years. Patients receiving protons have been followed up for 39-90 months; eight have tumor control, and one patient with cystic tumor, which required drainage 4 months after treatment, remains well at 47 months. One patient with substantial residual tumor who received 54 CGE developed bilateral visual loss 5 months later, but this condition improved markedly after reoperation. One patient with a large tumor who received 61.88 CGE had tumor control but severe short-term memory loss and required nursing care

2014-09-01

The TVT-Secur was introduced in 2006 as a less invasive alternative to retropubic and transobturator suburethral slings. This retrospective cohort study evaluated objective and subjective results in a series of 158 consecutive patients as well as complications and the reoperation rate after TVT-Secur procedure. Between November 2006 and June 2010 a total of 158 patients underwent a TVT-Secur procedure at a single institution. All patients underwent preoperative urodynamic testing. All patients were invited for follow-up including physical examination, urodynamic studies and subjective evaluation. A total of 96 patients (61%) were available for follow-up with a mean follow-up of 29.8 months (range 5-50, median 30). At follow-up, eight (8%) of 96 patients had reoperations for stress incontinence. There were no reoperations for bleeding/hematoma, tape erosions or obstructed micturition and there were no tape erosions or exposures. 29 patients (30%) had a negative cough stress test and 44 patients (46%) subjectively considered themselves "cured". Nine of 43 patients (21%) without urgency symptoms preoperatively developed de novo urgency; 24 of 35 patients (69%) with preoperative urgency complaints were free of urgency symptoms. At 2.4 years, the TVT-Secur appears to have a low adverse events profile but inferior results compared with traditional midurethral slings. Copyright © 2014 Elsevier Ireland Ltd.

Yan, Jingliang; Cohen, Ricardo; Aminian, Ali

Primary bariatric surgery has been proven to be effective in weight loss and improvement of weight-related metabolic co-morbidities. However, a small proportion of patients after bariatric surgery either have persistent hyperglycemia or relapse after initial remission of their metabolic disease. Revisional bariatric surgery has been evaluated extensively for weight recidivism and postoperative complications. However, there has not been any high-level evidence validating the utility of revisional bariatric surgery on recurrent metabolic diseases, especially diabetes. In this review of 30 studies, we aimed to summarize the evidence and determine whether revisional surgery can have a positive impact on metabolic diseases that were not reversed by initial bariatric intervention. Overall, 14-38% of patients had residual diabetes at the time of revisional surgery. Depending on the index surgery and subsequent reconstruction, revisions induced 20-80% additional excess weight loss, or further decrease of body mass index by 10-30%. Improvement of diabetes was seen in 65-100% of patients. Specifically, conversion to Roux-en-Y gastric bypass (RYGB) yielded improvement of diabetes in 79%, 72%, and 62% of patients who previously had vertical banded gastroplasty (VBG), adjustable gastric banding (AGB), or sleeve gastrectomy (SG), respectively. Converting AGB to SG improved diabetes in 65% of patients, and SG to duodenal switch improved diabetes in 79% of patients. Revision of the gastric pouch or stoma in RYGB yielded improvement of diabetes in 79% of patients. Further clinical and mechanistic research is needed to better delineate the role of revisional bariatric surgery in patients with residual metabolic disease.

Gouda, Biswanath P; Nelson, Thomas; Bhoyrul, Sunil

2012-08-01

Surgical myotomy is the gold standard in therapy for achalasia, but treatment failures occur and require revisional surgery. A MEDLINE search of peer-reviewed articles published in English from 1970 to December 2008 was performed using the following terms: esophageal achalasia, Heller myotomy, and revisional surgery. Thirty-three articles satisfied our inclusion criteria. A total of 12,727 patients, with mean age of 43.3 years (males 46% and females 50%), underwent Heller myotomy (open 94.8% and laparoscopic 5.2%). Revisional surgery was performed in 6.19%. Procedures performed included revision of the original myotomy or creation of a new myotomy with or without an antireflux procedure or esophagectomy. Reasons for reoperation were incomplete myotomy (51.8%), onset of reflux (34%), megaesophagus (16.2%), and esophageal carcinoma (3.04%). Systematic review of the literature for revisional surgery following Heller myotomy revealed a 6.19% rate of reoperation with a low mortality rate.

by ultrasound a small titanium seed containing typically 1-10 MBq of radioactive iodine-125 is placed in the centre of the nonpalpable breast lesion. During the operation the seed is located with a hand-held gamma probe. To date, only few cohort studies exist on the feasibility of RSL, and the method has only...... of patients with insufficient resection margin. These patients require a reoperation. New methods in the field of radioguided surgery (RGS) have been developed including radioguided occult lesion localization (ROLL) and radioactive seed localization (RSL). Especially RSL is a very promising technique. Guided...

An anaesthetic pre-operative assessment clinic reduces pre-operative inpatient stay in patients requiring major vascular surgery.

LENUS (Irish Health Repository)

O'Connor, D B

2012-02-01

BACKGROUND: Patients undergoing major vascular surgery (MVS) require extensive anaesthetic assessment. This can require extended pre-operative stays. AIMS: We investigated whether a newly established anaesthetic pre-operative assessment clinic (PAC) would reduce the pre-operative inpatient stay, avoid unnecessary investigations and facilitate day before surgery (DBS) admissions for patients undergoing MVS. PATIENT AND METHODS: One year following and preceding the establishment of the PAC the records of patients undergoing open or endovascular aortic aneurysm repair, carotid endarterectomy and infra-inguinal bypass were reviewed to measure pre-operative length of stay (LoS). RESULTS: Pre-operative LoS was significantly reduced in the study period (1.85 vs. 4.2 days, respectively, P < 0.0001). Only 12 out of 61 patients in 2007 were admitted on the DBS and this increased to 33 out of 63 patients (P = 0.0002). No procedure was cancelled for medical reasons. CONCLUSION: The PAC has facilitated accurate outpatient anaesthetic assessment for patients requiring MVS. The pre-operative in-patient stay has been significantly reduced.

Two patients with Björk Shiley mitral valve replacement had migration and embolization of the occluding disc. One patient suffered migration of the disc a few hours after surgery and the other had a strut fracture with disc translocation six years after the initial operation. Clinical signs in both cases were pulmonary edema, cardiogenic shock, and absence of prosthetic sounds. Both patients were reoperated on an emergency basis, recovering after a complicated postoperative course. They are on functional Class I, 8 and 1 years later, respectively, with their dislodged discs still in the abdominal aorta. The only hope for survival in these patients is emergency reoperation, once the prosthetic mitral valve dysfunction is confirmed.

Twenty-three surviving patients who were weaned from cardiopulmonary bypass with intraaortic balloon pump assistance returned for follow-up radionuclide left ventricular (LV) function and thallium 201 perfusion studies at a mean of 23 +/- 3 months following operation. It was found that despite profound intraoperative myocardial depression requiring intraaortic balloon assistance, 13 patients had no change (within 10%) in the resting LV ejection fraction compared with the preoperative measurement. Among all 23 patients, there was no difference between mean (+/- standard error of the mean) preoperative and postoperative resting LV ejection fraction (48 +/- 4 vs 46 +/- 4%, p . not significant [NS]). Only 11 patients had perioperative myocardial infarction documented by new Q waves in the electrocardiogram, by elevation of creatine kinase-MB fraction, or by defects on thallium 201 imaging not explained by documented myocardial infarction before operation. Overall, postoperative resting LV ejection fraction was not different from the preoperative value in patients with perioperative myocardial infarction (44 +/- 7 vs 47 +/- 5%, p . NS). Postoperative resting LV ejection fraction rose by greater than 10% compared with preoperative values in 4 patients (3 with aortic valve replacement), remained within the 10% limit in 9 patients, and fell by greater than 10% in 10 patients (7 with perioperative myocardial infarction). Only 4 out of 16 patients studied at follow-up with exercise radionuclide studies demonstrated a normal LV response to exercise (greater than 5% increase in LV ejection fraction). Thus, among survivors requiring intraaortic balloon pump assistance for weaning from cardiopulmonary bypass, LV performance at rest is frequently preserved. In addition, 11 of the 23 patients had evidence of perioperative myocardial infarction, indicating a component of reversible intraoperative LV dysfunction

Haemodilution and auto-transfusion were carried out in 103 consecutive patients having major orthopaedic surgery. The records of 99 patients were available for retrospective assessment of this technique. Fifty-six per cent of the patients did not require any homologous blood transfusion. Homologous blood transfusion was given to 44% of the patients, who used up 99 units of blood in their entire hospital stay. There was no morbidity such as transfusion reaction, infection, decrease in platelets or re-operation for bleeding associated with the procedure, although there was one death secondary to myocardial infarction. This technique offered an alternative method to reduce the use of homologous blood transfusion in major orthopaedic operations.

Radial retinotomy in the macula.

Bovino, J A; Marcus, D F

1984-01-01

Radial retinotomy is an operative procedure usually performed in the peripheral or equatorial retina. To facilitate retinal attachment, the authors used intraocular scissors to perform radial retinotomy in the macula of two patients during vitrectomy surgery. In the first patient, a retinal detachment complicated by periretinal proliferation and macula hole formation was successfully reoperated with the aid of three radial cuts in the retina at the edges of the macular hole. In the second patient, an intraoperative retinal tear in the macula during diabetic vitrectomy was also successfully repaired with the aid of radial retinotomy. In both patients, retinotomy in the macula was required because epiretinal membranes, which could not be easily delaminated, were hindering retinal reattachment.

Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders.

Despite the ongoing decrease in the frequency of complications after hepatectomy, biliary fistulas still occur and are associated with high morbidity and mortality rates. Here, we report on an unusual technique for managing biliary fistula following left hepatectomy in a patient in whom the right posterior segmental duct joined the left hepatic duct. The biliary fistula was treated with a combined radiologic and endoscopic procedure based on the “rendezvous technique”. The clinical outcome was good, and reoperation was not required.

Mechanical complications of prosthetic valves are increasing. The following report describes a case of fracture of a Björk-Shiley mitral prosthetic strut with dislogment of the valve occluder into the thoracic aorta. At the reoperation a new prosthesis was implanted but the patient died of acute heart failure. The diagnosis of valve disfunction must be made non invasively, because the time required for cardiac catherization usually constitutes a lethal delay. The only hope for survival is prompt surgical treatment.

Treatment of hidradenitis suppurativa (HS) is a difficult undertaking, especially as there is no consensus on what surgical technique is preferred. At our centre severe HS (Hurley II/III) is operated under general anaesthesia, mostly with the STEEP procedure. To investigate characteristics, surgical outcomes and patient satisfaction of HS patients who underwent deroofing or STEEP under general anaesthesia. A clinical records-based retrospective analysis was conducted of all patients who had surgery under general anaesthesia between 1999 and 2013. Patient satisfaction was retrospectively investigated with questionnaires. A total of 482 operations (363 primary operations and 119 re-operations) were performed during the study period. The proportion of women in the included population was 68%. The median diagnostic delay (patient's and doctor's delay) was 6.5 years. Relapses occurred after 29.2% of primary operations. Women had higher relapse rates than men [odds ratio 2.85 (1.07;7.61)]. Hypergranulation of the wound was the most common complication and occurred in 7% of all operations. The median score patients attributed to the medical effect of surgery was eight of 10 (zero corresponding to very dissatisfied and 10 to very satisfied). The diagnostic delay in HS is long due to a lack of knowledge in both patients and health care professionals, indicating that there is a need for education. Deroofing and the STEEP are effective surgical procedures in severe cases of HS and lead to a relatively high patient satisfaction. The postoperative relapse risk is higher in women. Prospective studies are required for the development of clear guidelines on the appropriate choice of surgery. © 2015 European Academy of Dermatology and Venereology.

Persistent variation in practice surrounds preoperative clopidogrel management at the time of vascular surgery. While some surgeons preferentially discontinue clopidogrel citing a perceived risk of perioperative bleeding, others will proceed with surgery in patients taking clopidogrel for an appropriate indication. The purpose of this study was to determine whether preoperative clopidogrel use was associated with significant bleeding complications during peripheral arterial surgery. We reviewed a prospective regional vascular surgery registry recorded by 66 surgeons from 15 centers in New England from 2003 to 2009. Preoperative clopidogrel use within 48 hours of surgery was analyzed among patients undergoing carotid endarterectomy (CEA), lower extremity bypass (LEB), endovascular abdominal aortic aneurysm repair (EVAR), and open abdominal aortic aneurysm repair (oAAA). Ruptured AAAs were excluded. Endpoints included postoperative bleeding requiring reoperation, as well as the incidence and volume of blood transfusion. Statistical analysis was performed using analysis of variance, Fisher exact, χ(2), and Wilcoxon rank-sum tests. Over the study interval, a total of 10,406 patients underwent surgery, including 5264 CEA, 2883 LEB, 1125 EVAR, and 1134 oAAA repair. Antiplatelet use among all patients varied, with 19% (n = 2010) taking no antiplatelet agents, 69% (n = 7132) taking aspirin (ASA) alone, 2.2% (n = 229) taking clopidogrel alone, and 9.7% (n = 1017) taking both ASA and clopidogrel. Clopidogrel alone or as dual antiplatelet therapy was most frequently used prior to CEA and least frequently prior to oAAA group (CEA 16.1%, LEB 9.0%, EVAR 6.5%, oAAA 5%). Reoperation for bleeding was not significantly different among patients based on antiplatelet regimen (none 1.5%, ASA 1.3%, clopidogrel 0.9%, ASA/clopidogrel 1.5%, P = .74). When analyzed by operation type, no difference in reoperation for bleeding was seen across antiplatelet regimens. There was also no

AIM: To analyze the difference in disease course and need for surgery in patients with Crohn’s disease (CD). METHODS: Data of 506 patients with incident CD were analyzed (age at diagnosis: 31.5 ± 13.8 years). Both hospital and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database, which includes incident CD patients diagnosed between January 1, 1977 and December 31, 2008. Follow-up data were collected until December 31, 2009. All patients included had at least 1 year of follow-up available. Patients with indeterminate colitis at diagnosis were excluded from the analysis. RESULTS: Overall, 73 patients (14.4%) required resective surgery within 1 year of diagnosis. Steroid exposure and need for biological therapy were lower in patients with early limited surgery (P < 0.001 and P = 0.09). In addition, surgery rates during follow-up in patients with and without early surgery differed significantly after matching on propensity scores (P < 0.001, HR = 0.23). The need for reoperation was also lower in patients with early limited resective surgery (P = 0.038, HR = 0.42) in a Kaplan-Meier and multivariate Cox regression (P = 0.04) analysis. However, this advantage was not observed after matching on propensity scores (PLogrank = 0.656, PBreslow = 0.498). CONCLUSION: Long-term surgery rates and overall exposure to steroids and biological agents were lower in patients with early limited resective surgery, but reoperation rates did not differ.

Valve-sparing root replacement (VSRR) is an established therapy for aortic root pathology. However, late aortic valve dysfunction requiring reoperation remains a primary concern of this procedure. This study examines risk factors for late aortic insufficiency (AI) and aortic stenosis (AS) after David V VSRR. A retrospective review from 2005 to 2015 at a US academic center identified 282 patients who underwent VSRR. Cox proportional hazards regression analysis was used to identify risk factors for late AI and AS after VSRR. The mean age was 46.4 years. Sixty-four patients (22.7%) had bicuspid valves, and 41 patients (14.5%) had Marfan syndrome. The incidence of reoperations was 27 (9.6%), and 42 cases (14.9%) presented with acute type A dissection. Operative mortality was 8 (2.8%). Seven-year survival was 90.9%. Seven-year cumulative incidence of reoperation, greater than 2+ AI and greater than moderate AS were 3.1%, 2.2%, and 0.8%, respectively. Multivariable analysis showed aortic root size 55 mm or larger (hazard ratio 3.44, 95% confidence interval: 1.27 to 9.29, p = 0.01) to be a risk factor for late AI whereas bicuspid valve (hazard ratio 16.07, 95% confidence interval: 3.12 to 82.68, p = 0.001) and cusp repair were found to be risk factors (hazard ratio 5.91, 95% confidence interval: 1.17 to 29.86, p = 0.03) for late AS. Valve-sparing root replacement can be performed with low operative risk and good overall long-term survival even in complex clinical settings. Durable valve function can be expected; however, aortic root size 55 cm or more, bicuspid valve anatomy, and cusp repair represent independent risk factors for late aortic valve dysfunction after these procedures.

The colostomy may be terminal or lateral, temporary or permanent. It may have psychological, medical or surgical complications. reporting the incidence of surgical complications of colostomies, their therapeutic management and trying to identify risk factors for their occurrence. A retrospective study for a period of 5 years in general surgery department, Habib Bourguiba hospital, Sfax, including all patients operated with confection of a colostomy. Were then studied patients reoperated for stoma complication. Among the 268 patients who have had a colostomy, 19 patients (7%) developed surgical stoma complications. They had a mean age of 59 years, a sex ratio of 5.3 and a 1-ASA score in 42% of cases. It was a prolapse in 9 cases (reconfection of the colostomy: 6 cases, restoration of digestive continuity: 3 cases), a necrosis in 5 cases (reconfection of the colostomy), a plicature in 2 cases (reconfection of the colostomy) a peristomal abscess in 2 cases (reconfection of the colostomy: 1 case, restoration of digestive continuity: 1 case) and a strangulated parastomal hernia in 1 case (herniorrhaphy). The elective incision and the perineal disease were risk factors for the occurrence of prolapse stomial. Surgical complications of colostomies remain a rare event. Prolapse is the most common complication, and it is mainly related to elective approach. Reoperation is often required especially in cases of early complications, with usually uneventful postoperative course.

Lung volume reduction surgery (LVRS) can benefit patients with severe emphysema. The aim of this study was to evaluate the outcome of LVRS performed in Iceland. A prospective study of 16 consecutive patients who underwent bilateral LVRS through median sternotomy between January 1996 and December 2008. All patients had disabling dyspnea, lung hyperinflation, and emphysema with upper lobe predominance. Preoperatively all patients underwent pulmonary rehabilitation. Spirometry, lung volumes, arterial blood gases and exercise capacity were measured before and after surgery. Mean follow-up time was 8.7 years. Mean age was 59.2 ± 5.9 years. All patients had a history of heavy smoking. There was no perioperative mortality and survival was 100%, 93%, and 63% at 1, 5, and 10 years, respectively. The forced expiratory volume in 1 second (FEV1) and the forced vital capacity (FVC) improved significantly after surgery by 35% (plung capacity, residual volume and partial pressure of CO2 also showed statistically significant improvements but exercise capacity, O2 consumption and diffusing capacity of the lung for CO did not change. Prolonged air leak (≥ 7 days) was the most common complication (n=7). Five patients required reoperation, most commonly for sternal dehiscence (n=4). In this small prospective study, FEV1 and FVC increased and lung volumes and PaCO2 improved after LVRS. Long term survival was satisfactory although complications such as reoperations for sternal dehiscence were common and hospital stay therefore often prolonged.

Laparoscopic subtotal hysterectomy in the era of minimally invasive surgery

Directory of Open Access Journals (Sweden)

2015-02-01

Full Text Available According to a nation-wide population-based study in Taiwan, along with the expanding concepts and surgical techniques of minimally invasive surgery, laparoscopic supracervical/subtotal hysterectomy (LSH has been blooming. Despite this, the role of LSH in the era of minimally invasive surgery remains uncertain. In this review, we tried to evaluate the perioperative and postoperative outcomes of LSH compared to other types of hysterectomy, including total abdominal hysterectomy (TAH, vaginal hysterectomy, laparoscopic-assisted vaginal hysterectomy, and total laparoscopic hysterectomy (TLH. From the literature, LSH has a better perioperative outcome than TAH, and comparable perioperative complications compared with laparoscopic-assisted vaginal hysterectomy. LSH had less bladder injury, vaginal cuff bleeding, hematoma, infection, and dehiscence requiring re-operation compared with TLH. Despite this, LSH has more postoperative cyclic menstrual bleeding and re-operations with extirpations of the cervical stump. LSH does, however, have a shorter recovery time than TAH due to the minimally invasive approach; and there is quicker resumption of coitus than TLH, due to cervical preservation and the avoidance of vaginal cuff dehiscence. LSH is therefore an alternative option when the removal of the cervix is not strictly necessary or desired. Nevertheless, the risk of further cervical malignancy, postoperative cyclic menstrual bleeding, and re-operations with extirpations of the cervical stump is a concern when discussing the advantages and disadvantages of LSH with patients.

The purpose of this study was to demonstrate the feasibility of performing peroral endoscopic myotomy (POEM) in the management of recurrent achalasia after failed myotomy. Eight patients presented to our institution between October 2010 and June 2013 with recurrent/persistent symptoms after prior laparoscopic Heller myotomy. Three patients underwent redo laparoscopic Heller myotomy, and five patients consented to redo myotomy with POEM. Demographics were similar between the groups with exception of age (POEM 69.5 vs. laparoscopic Heller myotomy (LHM) 34.5, p = 0.003). Preoperative Eckardt scores, motility, and prior interventions were not significantly different. Three patients who underwent POEM and two who underwent laparoscopic Heller myotomy had prior fundoplication. There was one perforation identified after laparoscopic Heller myotomy and one patient with persistent subcutaneous emphysema after POEM. Both POEM and laparoscopic Heller myotomy demonstrated significant improvement in symptoms and Eckardt scores at average follow-up of approximately 5 months (p myotomy even in the presence of prior fundoplication. The procedure can be performed safely using a similar technique as for primary myotomy with the exception of creating the myotomy laterally along the right side of the esophagus and lesser curvature avoiding the previous anterior myotomy.

To determine the contribution of cytochrome P4502C9 (CYP2C9), vitamin K epoxide reductase (VKORC1) and factor VII genotypes, age, body mass index (BMI), international normalized ratio (INR) and other individual patient characteristics on warfarin dose requirements in an adult Turkish population. Blood samples were collected from 101 Turkish patients. Genetic analyses for CYP2C9*2 and *3, VKORC1 -1639 G>A and factor VII -401 G>T polymorphisms were performed. Age, INR, BMI values and other individual patient characteristics were also recorded. The mean daily warfarin dosage was significantly higher in patients with the CYP2C9*1/*1 genotype than in the CYP2C9*2/*2 and CYP2C9*1/*3 groups (p ≤ 0.05). With respect to the VKORC1 -1639 G>A polymorphism, the mean warfarin daily dose requirement was higher in the wild type group compared to the heterozygous group (p≤0.001). The mean daily dose requirement for patients with the GG form of factor VII was significantly higher than that of patients with the TT genotype (p ≤ 0.05). Age, gender, BMI, INR had no statistically significant correlation with warfarin dose (p ≥ 0.05). Polymorphisms in CYP2C9, VKORC1 and factor VII did partially affect daily warfarin dose requirements, while age, gender, BMI and INR do not. However, further case-control studies with a larger study size and different genetic loci are needed to confirm our study.

Durability of mitral valve repair for mitral regurgitation due to degenerative mitral valve disease.

Science.gov (United States)

David, Tirone E

2015-09-01

Degenerative diseases of the mitral valve (MV) are the most common cause of mitral regurgitation in the Western world and the most suitable pathology for MV repair. Several studies have shown excellent long-term durability of MV repair for degenerative diseases. The best follow-up results are obtained with isolated prolapse of the posterior leaflet, however even with isolated prolapse of the anterior leaflet or prolapse of both leaflets the results are gratifying, particularly in young patients. The freedom from reoperation on the MV at 15 years exceeds 90% for isolated prolapse of the posterior leaflet and it is around 70-85% for prolapse of the anterior leaflet or both leaflets. The degree of degenerative change in the MV also plays a role in durability of MV repair. Most studies have used freedom from reoperation to assess durability of the repair but some studies that examined valve function late after surgery suggest that recurrent mitral regurgitation is higher than estimated by freedom from reoperation. We can conclude that MV repair for degenerative mitral regurgitation is associated with low probability of reoperation for up to two decades after surgery. However, almost one-third of the patients develop recurrent moderate or severe mitral regurgitation suggesting that surgery does not arrest the degenerative process.

A consecutive series of 47 adult patients with chronic subdural hematoma was studied in respect to postoperative follow-up CT after burr hole evacuation. In 15 of our patients, the CT scan was normalized within 60 days. Six patients required reoperation because of reaccumulation or of poor re-expansion, and in 13 patients the follow-up CT showed a persisting subdural fluid collection even after 60 postoperative days. Further studying the correlation between the prognosis on follow-up CT and various factors, such as patient's age, preoperative neurological condition and CT findings or others, authors found that the elderly, especially older than 70 years, had a poor prognosis, and that the prognosis was correlated to the density and the thickness of hematoma on preoperative CT scan.

Purpose: A phase I dose escalation of hypofractionated stereotactic radiotherapy (H-SRT) in recurrent or persistent malignant gliomas as a means of increasing the biologically effective dose and decreasing the high rate of reoperation due to toxicity associated with single-fraction stereotactic radiosurgery (SRS) and brachytherapy. Materials and Methods: From November 1994 to September 1996, 25 lesions in 20 patients with clinical and/or imaging evidence of malignant glioma persistence or recurrence received salvage H-SRT. Nineteen patients at the time of initial diagnosis had glioblastoma multiforme (GBM) and one patient had an anaplastic astrocytoma. All of these patients with tumor persistence or recurrence had received initial fractionated radiation therapy (RT) with a mean and median dose of 60 Gy (44.0-72.0 Gy). The median time from completion of initial RT to H-SRT was 3.1 months (0.7-45.5 months). Salvage H-SRT was delivered using daily 3.0-3.5 Gy fractions (fxs). Three different total dose levels were sequentially evaluated: 24.0 Gy/3.0 Gy fxs (five lesions), 30.0 Gy/3.0 Gy fxs (10 lesions), and 35.0 Gy/3.5 Gy fxs (nine lesions). Median treated tumor volume measured 12.66 cc (0.89-47.5 cc). The median ratio of prescription volume to tumor volume was 2.8 (1.4-5.0). Toxicity was judged by RTOG criteria. Response was determined by clinical neurologic improvement, a decrease in steroid dose without clinical deterioration, and/or radiologic imaging. Results: No grade 3 toxicities were observed and no reoperation due to toxicity was required. At the time of analysis, 13 of 20 patients had died. The median survival time from the completion of H-SRT is 10.5 months with a 1-year survival rate of 20%. Neurological improvement was found in 45% of patients. Decreased steroid requirements occurred in 60% of patients. Minor imaging response was noted in 22% of patients. Using Fisher's exact test, response of any kind correlated strongly to total dose (p = 0.0056). None

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

Full Text Available Background. The management and outcomes of occult hemopneumothorax in blunt trauma patients who required mechanical ventilation are not well studied. We aimed to study patients with occult hemopneumothorax on mechanical ventilation who could be carefully managed without tube thoracostomy. Methods. Chest trauma patients with occult hemopneumothorax who were on mechanical ventilation were prospectively evaluated. The presence of hemopneumothorax was confirmed by CT scanning. Hospital length of stay, complications, and outcome were recorded. Results. A total of 56 chest trauma patients with occult hemopneumothorax who were on ventilatory support were included with a mean age of 36 ± 13 years. Hemopneumothorax was managed conservatively in 72% cases and 28% underwent tube thoracostomy as indicated. 29% of patients developed pneumonia, 16% had Acute Respiratory Distress Syndrome (ARDS, and 7% died. Thickness of hemothorax, duration of mechanical ventilation, and development of ARDS were significantly associated with tube thoracostomy in comparison to no-chest tube group. Conclusions. The majority of occult hemopneumothorax can be carefully managed without tube thoracostomy in patients who required positive pressure ventilation. Tube thoracotomy could be restricted to those who had evidence of increase in the size of the hemothorax or pneumothorax on follow-up chest radiographs or developed respiratory compromise.

Patients may perceive resident procedural participation as detrimental to their outcome. Our objective is to investigate whether otolaryngology-head and neck surgery (OHNS) housestaff participation is associated with surgical morbidity and mortality. Case-control study. OHNS patients were analyzed from the American College of Surgeons National Surgical Quality Improvement Program 2006 to 2013 databases. We compared the incidence of 30-day postoperative morbidity, mortality, readmissions, and reoperations in patients operated on by resident surgeons with attending supervision (AR) with patients operated on by an attending surgeon alone (AO) using cross-tabulations and multivariable regression. There were 27,018 cases with primary surgeon data available, with 9,511 AR cases and 17,507 AO cases. Overall, 3.62% of patients experienced at least one postoperative complication. The AR cohort had a higher complication rate of 5.73% than the AO cohort at 2.48% (P < .001). After controlling for all other variables, there was no significant difference in morbidity (odds ratio [OR] = 1.05 [0.89 to 1.24]), mortality (OR = 0.91 [0.49 to 1.70]), readmission (OR = 1.29 [0.92 to 1.81]), or reoperation (OR = 1.28 [0.91 to 1.80]) for AR compared to AO cases. There was no difference between postgraduate year levels for adjusted 30-day morbidity or mortality. There is an increased incidence of morbidity, mortality, readmission, and reoperation in OHNS surgical cases with resident participation, which appears related to increased comorbidity with AR patients. After controlling for other variables, resident participation was not associated with an increase in 30-day morbidity, mortality, readmission, or reoperation odds. These data suggest that OHNS resident participation in surgical cases is not associated with poorer short-term outcomes. 3b Laryngoscope, 126:2263-2269, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

Objective To compare the safety and efficacy of hysteroscopic sterilization with the “Essure” device with laparoscopic sterilization in a large, all-inclusive, state cohort. Design Population based cohort study. Settings Outpatient interventional setting in New York State. Participants Women undergoing interval sterilization procedure, including hysteroscopic sterilization with Essure device and laparoscopic surgery, between 2005 and 2013. Main outcomes measures Safety events within 30 days of procedures; unintended pregnancies and reoperations within one year of procedures. Mixed model accounting for hospital clustering was used to compare 30 day and 1 year outcomes, adjusting for patient characteristics and other confounders. Time to reoperation was evaluated using frailty model for time to event analysis. Results We identified 8048 patients undergoing hysteroscopic sterilization and 44 278 undergoing laparoscopic sterilization between 2005 and 2013 in New York State. There was a significant increase in the use of hysteroscopic procedures during this period, while use of laparoscopic sterilization decreased. Patients undergoing hysteroscopic sterilization were older than those undergoing laparoscopic sterilization and were more likely to have a history of pelvic inflammatory disease (10.3% v 7.2%, P<0.01), major abdominal surgery (9.4% v 7.9%, P<0.01), and cesarean section (23.2% v 15.4%, P<0.01). At one year after surgery, hysteroscopic sterilization was not associated with a higher risk of unintended pregnancy (odds ratio 0.84 (95% CI 0.63 to 1.12)) but was associated with a substantially increased risk of reoperation (odds ratio 10.16 (7.47 to 13.81)) compared with laparoscopic sterilization. Conclusions Patients undergoing hysteroscopic sterilization have a similar risk of unintended pregnancy but a more than 10-fold higher risk of undergoing reoperation compared with patients undergoing laparoscopic sterilization. Benefits and risks of both procedures

The aim of this study was to determine the long-term clinical efficacy and complications of neuromodulation with a unilateral sacral foramen electrode in 36 patients with chronic voiding dysfunction. Following a positive effect of a percutaneous nerve evaluation test, patients underwent open surgery. A permanent electrode was implanted in 24 patients with urge incontinence, in 6 with urgency-frequency syndrome, and in 6 with nonobstructive urinary retention. After an average follow-up period of 37.8 months, 19 patients (52.8%) continue to benefit from the neuromodulation with a significant improvement of symptoms and urodynamic parameters. The median duration of the therapeutic effect for the total study population was longer than 60 months. No significant difference in the median duration of therapeutic effect with regard to sex, the type of voiding disorder, or the implant pulse generator was found. However, in patients with previous psychological disorders the median duration of therapeutic effect was only 12 months (P = 0.008). Complications were mild. In the group of patients in whom the therapeutic effect remains, 37 reoperations have had to be performed. We conclude that although reoperations were needed to overcome technical problems, patients can achieve lasting symptomatic improvement. Since technical changes in the equipment have reduced the number of complications, even better results can be expected in terms of the reoperation rate.

Full Text Available Background. The aim of this study was to investigate patient outcomes and nutritional deficiencies following sleeve gastrectomy (SG during a follow-up of two years. Methods. Over a period of 56 months, all consecutive patients who underwent SG were documented in this prospective, single-center, observational study. The study endpoints included operative time, complication rates, nutritional deficiencies and percentage of excess weight loss (%EWL. Results. From September 26, 2005 to May 28, 2009, 82 patients (female : male = 48 : 34 with a mean age of 43.3 years (range: 22–64 and a preoperative BMI of 52.5 kg/m² (range: 36.8–77.0 underwent SG. Major complications were observed in 9.8% of the patients, with 1 death. During follow up 51.2% of patients were supplemented with iron, 36.6% with zinc, 37.8% with calcium, 26.8% with vitamin D, 46.3% with vitamin B12 and 41.5% with folic acid. %EWL was 54.3, 65.3 and 62.6% after 6, 12 and 24 months. Conclusion. SG as a single step procedure is an effective bariatric intervention. Nutritional deficiencies after SG can be detected by routine nutritional screening. Our results show that Vitamin B12 supplementation should suggest routinely after SG.

Autologous osteochondral mosaicplasty and TruFit Bone graft substitute plugs are methods used to repair symptomatic articular cartilage defects in the adult knee. There have been no comparative studies of the two techniques. This retrospective study assessed functional outcome of patients using the EQ-5D, Knee Injury and Osteoarthritis Outcome Score (KOOS) and Modified Cincinnati scores at follow-up of 1-5 years. There were 66 patients in the study (35 TruFit and 31 Mosaicplasty): 44 males and 22 females with a mean age of 37.3 years (SD 12.6). The mean BMI was 26.8. Thirty-six articular cartilage lesions were due to trauma, twenty-six due to osteochondritis dissecans and three due to non-specific degenerative change or unknown. There was no difference between the two groups age (n.s.), sex (n.s.), BMI (n.s.), defect location (n.s.) or aetiology (n.s.). The median follow-up was 22 months for the TruFit cohort and 30 months for the mosaicplasty group. There was no significant difference in the requirement for re-operation (n.s). Patients undergoing autologous mosaicplasty had a higher rate of returning to sport (p = 0.006), lower EQ-5D pain scores (p = 0.048) and higher KOOS activities of daily living (p = 0.029) scores. Sub-group analysis showed no difference related to the number of cases the surgeon performed. Patients requiring re-operation had lower outcome scores regardless of their initial procedure. This study demonstrated significantly better outcomes using two validated outcome scores (KOOS, EQ-5D), and an ability to return to sport in those undergoing autologous mosaicplasty compared to those receiving TruFit plugs.

Pannus formation after aortic valve replacement is not common, but obstruction due to chronic pannus is one of the most serious complications of valve replacement. The causes of pannus formation are still unknown and effective preventive methods have not been fully elucidated. We reviewed our clinical experience of all patients who underwent reoperation for prosthetic aortic valve obstruction due to pannus formation between 1973 and 2004. We compared the initial 18-year period of surgery, when the Björk-Shiley tilting-disk valve was used, and the subsequent 13-year period of surgery, when the St. Jude Medical valve was used. Seven of a total of 390 patients (1.8%) required reoperation for prosthetic aortic valve obstruction due to pannus formation. All seven patients were women; four patients underwent resection of the pannus and three patients needed replacement of the valve. The frequency of pannus formation in the early group was 2.4% (6/253), whereas it was 0.73% (1/137) in the late group (P Pannus was localized at the minor orifice of the Björk-Shiley valve in the early group and turbulent transvalvular blood flow was considered to be one of the important factors triggering its growth. We also consider that small bileaflet valves have the possibility of promoting pannus formation and that the implantation of a larger prosthesis can contribute to reducing the occurrence of pannus.

A Preoperative Medical History and Physical Should Not Be a Requirement for All Cataract Patients.

Science.gov (United States)

Schein, Oliver D; Pronovost, Peter J

2017-07-01

Cataract surgery poses minimal systemic medical risk, yet a preoperative general medical history and physical is required by the Centers for Medicare and Medicaid Services and other regulatory bodies within 1 month of cataract surgery. Based on prior research and practice guidelines, there is professional consensus that preoperative laboratory testing confers no benefit when routinely performed on cataract surgical patients. Such testing remains commonplace. Although not yet tested in a large-scale trial, there is also no evidence that the required history and physical yields a benefit for most cataract surgical patients above and beyond the screening performed by anesthesia staff on the day of surgery. We propose that the minority of patients who might benefit from a preoperative medical history and physical can be identified prospectively. Regulatory agencies should not constrain medical practice in a way that adds enormous cost and patient burden in the absence of value.

Rapid progress has been made in the treatment of Marfan syndrome. Today, the treatment is relatively established and the results have also improved. Even if surgery is performed, however, vascular lesions may recur late after operation and late prognosis is poor considering the age of patients. Issues such as whether a reoperation should be conducted or how the late results might be improved are subjects of debate. Based on an analysis of recent late data, we have performed operations according to the new treatment policy, and here report the results. A total of 203 consecutive operations were conducted in 141 patients with Marfan syndrome who underwent surgery for aortic aneurysm at our department between February 1973 and August 2001. The mean age of patients was 39 (11 years with a male/female ratio of 95:46. At the first operation, 72 patients were diagnosed with annuloaortic ectasia (AAE), 17 patients with AAE + chronic dissection (DeBakey I), 14 patients with AAE + chronic dissection (DeBakey II), 6 patients with AAE + acute dissection (Stanford A), 11 patients with AAE + dissection (DeBakey III), 9 patients with dissection (DeBakey III) only, 3 patients with AAE + abdominal aortic aneurysm only, and 2 patients with abdominal aortic aneurysm only. The cause of reoperation were a new lesion in 17 patients, dissection in 13 patients and a true aneurysm in 4 patients. In 36 patients, an increase in the remaining lesion occurred or a scheduled stage 2 operation was performed. Reoperation was performed following the Bentall operation in 7 patients, dehiscence of the anastomotic region of the coronary artery in 5 patients, aneurysm of the anastomotic region of the coronary artery in 1 patients, and infection of the artificial valve with aneurysm of the anastomotic region of the coronary artery in 1 patient. Hospital deaths were reported in 8 (6%) patients who underwent composite valve graft replacement (including simultaneous arch replacement) for AAE. Hospital

Video-assisted thoracoscopic surgery for acute thoracic trauma

Directory of Open Access Journals (Sweden)

Michael Goodman

2013-01-01

Full Text Available Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13% following blunt injury and 20 (87% after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury.

Cerebrospinal fluid leakage into the subdural space: possible influence on the pathogenesis and recurrence frequency of chronic subdural hematoma and subdural hygroma.

The purpose of this study was to clarify whether cerebrospinal fluid (CSF) leakage into the subdural space is involved in the genesis of chronic subdural hematoma (CSDH) and subdural hygroma (SH) and to clarify whether this leakage of CSF into the subdural space influences the postoperative recurrence rate of CSDH and SH. In this prospective observational study, 75 cases involving patients treated surgically for CSDH (67 patients) or SH (8 patients) were evaluated with respect to clinical and radiological findings at presentation, the content of beta -trace protein (beta TP) in the subdural fluid (betaTPSF) and serum (betaTPSER), and the CSDH/SH recurrence rate. The betaTPSF was considered to indicate an admixture of CSF to the subdural fluid if betaTPSF/betaTPSER>2. The median beta TPSF level for the whole patient group was 4.29 mg/L (range 0.33-51 mg/L). Cerebrospinal fluid leakage, as indicated by betaTPSF/betaTPSER>2, was found to be present in 93% of the patients with CSDH and in 100% of the patients with SH (p=0.724). In patients who later had to undergo repeated surgery for recurrence of CSDH/SH, the betaTPSF concentrations (median 6.69 mg/L, range 0.59-51 mg/L) were significantly higher (p=0.04) than in patients not requiring reoperation (median 4.12 mg/L, range 0.33-26.8 mg/L). As indicated by the presence of betaTP in the subdural fluid, CSF leakage into the subdural space is present in the vast majority of patients with CSDH and SH. This leakage could be involved in the pathogenesis of CSDH and SH. Patients who experience recurrences of CSDH and SH have significantly higher concentrations of betaTPSF at initial presentation than patients not requiring reoperation for recurrence. These findings are presented in the literature for the first time and have to be confirmed and expanded upon by further studies.

Current surgical indications for Graves' disease include intractability to medical and/or radioablative therapy, compressive symptoms, and worsening ophthalmopathy. Total thyroidectomy for Graves' disease may be technically challenging and lead to untoward perioperative outcomes. This study examines outcomes in patients with Graves' disease who underwent total thyroidectomy and assesses its safety for this patient population. A retrospective cross-sectional analysis was performed using the Nationwide Inpatient Sample database from 2006 to 2011. Total thyroidectomy performed in patients with Graves' disease, benign multinodular goiter (MNG), and thyroid cancer was identified. Demographic factors, comorbidities, and postoperative complications were evaluated. Chi-square, one-way analysis of variance, and risk-adjusted multivariable logistic regression were performed. Of 215,068 patients who underwent total thyroidectomy during the study period, 11,205 (5.2%) had Graves' disease, 110,124 (51.2%) MNG, and 93,739 (43.6%) thyroid malignancy. Patients with Graves' disease were younger than MNG and thyroid cancer patients (M age  = 42.8 years vs. 55.5 and 51.0 years; p Graves' disease group included a higher proportion of women (p Graves' disease was independently associated with a higher risk of vocal-cord paralysis (odds ratio [OR] = 1.36 [confidence interval (CI) 1.08-1.69]), tracheostomy (OR = 1.35 [CI 1.1-1.67]), postoperative hypocalcemia (OR = 1.65 [CI 1.54-1.77]), and hematoma requiring reoperation (OR = 2.79 [CI 2.16-3.62]) compared to MNG patients. High-volume centers for total thyroidectomy were independently associated with lower risk of postoperative complications, including in patients with Graves' disease. Despite low overall morbidity following total thyroidectomy, Graves' disease patients are at increased risk of postoperative complications, including bleeding, vocal-cord paralysis, tracheostomy, and hypocalcemia. These risks appear

Anastomotic configurations may be a predictor of postoperative recurrence for Crohn's disease. One previous meta-analysis showed side-to-side anastomosis was associated with fewer anastomotic leaks but did not reduce postoperative recurrence rates. After 2007, more articles that found distinct results were published. We aimed to update the meta-analysis comparing outcomes between side-to-side anastomosis and other anastomotic configurations after intestinal resection for patients with Crohn's disease. A literature search that included PubMed, EMBASE, the Science Citation Index, and the Cochrane Library was conducted to identify studies up to May 2012. Trials comparing side-to-side anastomosis with other anastomotic configurations for Crohn's disease were analyzed. Sensitivity analysis and heterogeneity assessment were also performed. Eleven trials compared side-to-side with other anastomotic configurations were included. Overall, results showed a significant reduction in the overall postoperative complications [n = 777; odds ratio (OR) = 0.60; P = 0.01], but side-to-side anastomosis did not reduce the anastomotic leak rate (n = 879; OR = 0.48; P = 0.07), complications other than anastomotic leak (n = 777; OR = 0.72; P = 0.13), endoscopic recurrence rates [hazard ratio (HR) = 0.73; P = 0.07], symptomatic recurrence rates (HR = 0.74; P = 0.20), and reoperation rates for recurrence (HR = 0.37; P = 0.06). Sensitivity analysis including two randomized controlled trials found no significant differences in short-term complications between the two groups. Sensitivity analysis including nine trials comparing only stapled side-to-side anastomosis with other anastomotic configurations showed stapled side-to-side anastomosis could reduce reoperation rates (HR = 0.38; P = 0.01). Side-to-side anastomosis did not reduce short-term complications and postoperative recurrence for Crohn's disease. Stapled side-to-side anastomosis may lead to fewer reoperations needed for recurrence

Skin grafts can be used effectively to cover burn injuries. A critical element of this treatment is the adherence of the graft to the wound bed. Honey has been shown to increase the adherence of skin grafts to wound beds and have antibacterial and anti-inflammatory effects and increase healing rate of wounds. We therefore devised a clinical trial to determine the effect of honey on skin graft fixation in burn injuries. Sixty patients were included in this study (in 30 patients, graft was fixed with medical honey, and in 30 patients, it was fixed with dressing or suturing). All patients in two groups were evaluated for infection, graft loss, graft contraction, severity of pain, and need for re-operation. The most common cause of burn was kerosene. Honey significantly decreased infection rate on fifth day and reduced the patient pain. The mean hospital stay was shorter in honey group. Contraction of graft was significantly less in honey group. Honey has strong adhesive properties for skin graft fixation. Medical honey is a natural material, not synthetic. For this reason, we can advise the application of medical honey for the fixation of split thickness skin graft.

Since 1986 403 patients have been treated according to the following programme: successive preparation for surgery, the operative intervention chosen individually for each patient, the purposeful medical rehabilitation. Different types of vagotomy with draining operations were performed in 85.6% of the cases, stomach resection--in 14.4% of the patients. The mortality rate was 0%. The indications for various types of vagotomy, stomach resection and different types of draining operations were determined. Rehabilitation of 55% of the patients after the operative treatment took place at the gastroenterological department, the others--at an outpatient department. The indications for rehabilitation, its volume and time were established. The best remote results in the follow-up periods up to five years were obtained after truncal vagotomy and stomach resection. Ulcer recurrences were noted in 3.5% and 5.2% of the cases respectively. Recurrences of the disease were noted in 7.8% after combined vagotomy and in more than 20% after SPV. Nine patients out of 34 with recurrent ulcers were reoperated with good results, the others were successfully treated by conservative therapy.

A primary measure of the success of a procedure is the whether or not additional surgery may be necessary. Multi-institutional studies regarding the need for reoperation after bariatric surgery are scarce. The purpose of this study is to evaluate the rate of revisions/conversions (RC) after 3 common bariatric procedures over 10 years in the state of New York. University Hospital, involving a large database in New York State. The Statewide Planning and Research Cooperative System database was used to identify all patients undergoing laparoscopic adjustable gastric banding (LAGB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB) between 2004 and 2010. Patients were followed for RC to other bariatric procedures for at least 4 years (up to 2014). Multivariable cox proportional hazard regression analysis was performed to identify risk factors for additional surgery after each common bariatric procedure. Multivariable logistic regression was used to check the factors associated with having ≥2 follow-up procedures. There were 40,994 bariatric procedures with 16,444 LAGB, 22,769 RYGB, and 1781 SG. Rate of RC was 26.0% for LAGB, 9.8% for SG, and 4.9% for RYGB. Multiple RC ( = />2) were more common for LAGB (5.7% for LAGB, .5% for RYGB, and .2% for LSG). Band revision/replacements required further procedures compared with patients who underwent conversion to RYGB/SG (939 compared with 48 procedures). Majority of RC were not performed at initial institution (68.2% of LAGB patients, 75.9% for RYGB, 63.7% of SG). Risk factors for multiple procedures included surgery type, as LAGB was more likely to have multiple RC. Reoperation was common for LAGB, but less common for RYGB (4.9%) and SG (9.8%). RC rate are almost twice after SG than after RYGB. LAGB had the highest rate (5.7%) of multiple reoperations. Conversion was the procedure of choice after a failed LAGB.

To determine the value of aortic valve repair rather than replacement for valve dysfunction, we assessed late outcomes of various repair techniques in the contemporary era. From January 2001 to January 2011, aortic valve repair was planned in 1,124 patients. Techniques involved commissural figure-of-8 suspension sutures (n = 63 [6.2%]), cusp repair with commissuroplasty (n = 481 [48%]), debridement (n = 174 [17%]), free-margin plication (n = 271 [27%]) or resection (n = 75) or both, or annulus repair with resuspension (n = 230 [23%]), root reimplantation (n = 252 [25%]), or remodeling (n = 35 [3.5%]). Planned repair was aborted for replacement in 115 patients (10%); risk factors included greater severity of aortic regurgitation (AR; p = 0.0002) and valve calcification (p < 0.0001). In-hospital outcomes for the remaining 1,009 patients included death (12 [1.2%]), stroke (13 [1.3%]), and reoperation for valve dysfunction (14 [1.4%]). Freedom from aortic valve reoperation at 1, 5, and 10 years was 97%, 93%, and 90%, respectively. Figure-of-8 suspension sutures, valve resuspension, and root repair and replacement were least likely to require reoperation; cusp repair with commissural sutures, plication, and commissuroplasty was most likely (p < 0.05). Survival at 1, 5, and 10 years was 96%, 92%, and 83%. Immediate postoperative AR grade was none-mild (94%), moderate (5%), and severe (1%). At 10 years after repair, AR grade was none (20%), mild (33%), moderate (26%), and severe (21%). Patients undergoing root procedures were less likely to have higher-grade postoperative AR (p < 0.0001). Valve repair is effective and durable for treating aortic valve dysfunction. Greater severity of AR preoperatively is associated with higher likelihood of repair failure. Commissural figure-of-8 suspension sutures and repair with annular support have the best long-term durability. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

MEN1 patients requiring resection of neuroendocrine tumors (pNET) are frequently young, active patients in whom a minimal access approach minimizes perioperative morbidity and splenic preservation decreases the risk of post-splenectomy sepsis. Laparoscopic spleen preserving distal pancreatectomy can be performed with removal (Warshaw's technique) or preservation of the splenic vessels, the later having a higher rate of successful splenic preservation. This is an active, 16-year-old Jehovah's Witness with trifocal nonfunctioning neuroendocrine tumor in the proximal body and tail of the pancreas as part of MEN1 syndrome. A spleen preserving distal pancreatectomy was performed with the final pathology showing three pNET with low mitotic count and three lymph nodes free of cancer (final stage pT2pN0). This video demonstrates patient and trocar positioning as well as operative tactics for a laparoscopic distal pancreatectomy with preservation of splenic vessels. Intraoperative ultrasound is crucial in assessing pNETs' relation to critical vessels, pancreatic duct, and to exclude synchronous lesions. The video focuses on safe laparoscopic creation of the retropancreatic tunnel and dissecting the pancreas off the splenic vessels using novel energy devises to control direct splenic venous branches into the pancreas. Improvements in laparoscopic techniques and technology have enabled surgeons to preserve the major splenic vessels to avoid splenic infarcts, abscesses and re-operations, and minimize the risk of left-sided portal hypertension. Splenic preservation is particularly important in young MEN1 patients undergoing laparoscopic pancreatectomy for pNET due to the increased risk of overwhelming post-splenectomy sepsis.

The Solo Smart pericardial aortic valve has been widely used in Europe as an option for aortic valve replacement (AVR). We are reporting early and midterm clinical outcomes of AVR with the Solo Smart valve in a single North America center. This is a retrospective study of 270 consecutive patients who had AVR at Mazankowski Alberta Heart Institute from February 2011 to March 2015. Follow-up and echocardiographic data were collected retrospectively from electronic and paper charts. Univariate and multivariate analysis were performed to evaluate the results. The mean age was 71.2±10.0 years, 67.4% were male, and 79.3% had combined procedures. Mean STS Score was 4.18±3.91. Early mortality was 3.7% for the entire group and 0% for isolated aortic valve replacement group. Mean cross-clamp time for isolated AVR and AVR with concomitant procedure was 70.8±12.7min and 117.0±45.0min, respectively. Permanent pacemaker implantation was necessary in 2.2% of patients. Echocardiography demonstrated a reduction in mean gradients from 40.8±17.4mmHg to 7.6±3.7 mmHg and peak gradient from 72.5 ± 48.8 mmHg to 15.5±7.5 mmHg. The 1-, 3-, and 5- year overall survival was 93.0%, 86.5% and 75.9%, respectively. At 5 years, freedom from valve-related death was 92.4%, freedom from structural valve deterioration and freedom from aortic valve reoperation were 96.4% and 98%, respectively. The Solo Smart valve is safe and has excellent hemodynamic performance. Aortic valve reoperation and rates of valve-related adverse events during midterm follow-up were low.

To assess the intraocular pressure control (IOP), changes in visual acuity, complications, reoperation rates and risk factors for failure following Ahmed glaucoma valve implantation in pediatric eyes with glaucoma. The medical records of consecutive patients with glaucoma who underwent Ahmed glaucoma valve implantation from January 2000 to December 2009) were retrospectively reviewed. Only one eye of each patient was included. Subgroup analysis was performed in three groups; group 1 included phakic eyes with primary congenital glaucoma, juvenile open-angle glaucoma, or glaucoma associated with ocular anomalies; group 2 included eyes with glaucoma in aphakia or pseudophakia; group 3 included eyes with other diagnoses. A successful outcome was defined as final IOP between 6 mm Hg and 18 mm Hg without loss of light perception or reoperation for glaucoma. A total of 71 eyes in 71 patients: 15 (21%) in group 1, 47 (66%) in group 2, and 9 (13%) in group 3 were included Successful IOP control was achieved in 44 eyes of 44 patients (62%). Cumulative probabilities of success by Kaplan-Meier analysis at 12 and 24 months was 97% and 80% for the entire group, 100% and 82% for group 1, 95% and 86% for group 2, and 90% and 42% for group 3. Reoperation was necessary for 18 patients (25%), either for tube-related complications or for IOP control. The only significant risk factor for failure was the category of diagnosis (P = 0.029). Ahmed glaucoma valve implantation is an option in the management of pediatric glaucoma; however, reoperations for tube related complications or for persistent elevated IOP is frequently needed.

A competent aortic valve is essential to providing effective left ventricular assist device support. We have adopted a practice of central aortic valve closure by placing a simple coaptation stitch at left ventricular assist device implantation in patients with significant aortic insufficiency. We conducted a follow-up study to evaluate the efficacy and durability of this procedure. The study included patients who had undergone continuous flow left ventricular assist device implantation. The patients were divided into 2 groups, those who did not require any aortic procedure because the valve was competent and those who underwent central aortic valve closure for mild or greater aortic regurgitation. The clinical endpoints were mortality, progression or recurrence of aortic insufficiency, and reoperation for aortic valve pathologic features. Aortic insufficiency was measured qualitatively from mild to severe on a scale of 0 to 5. A total of 123 patients received continuous flow left ventricular assist devices from February 2007 to August 2011. Of those, 18 (15%) underwent central aortic valve closure at left ventricular assist device implantation because of significant aortic insufficiency (1.8 ± 1.4) and 105 who did not (competent aortic valve, 0.15 ± 0.43; P assist device-supported patients, with follow-up extending into 2 years. Although aortic insufficiency progressed over time in those with minimal native valve regurgitation initially, no such progression was noted in those with central aortic valve closure. Additional investigation is needed to evaluate whether prophylactic central aortic valve closure should be performed at left ventricular assist device implantation to avoid problematic aortic regurgitation developing over time, in particular in patients undergoing left ventricular assist device implantation for life-long (destination therapy) support.

2012-02-03

Although it is widely accepted that aspirin will increase the risk of intra- and post-operative bleeding, clinical studies have not consistently supported this assumption. We aimed to assess the effect of pre-operative aspirin on blood loss and transfusion requirements in patients undergoing emergency fixation of femoral neck fractures. A prospective case-control study was undertaken in patients presenting with femoral neck fractures. Parameters recorded included intra-operative blood loss, post-operative blood loss, transfusion requirements and peri-operative reduction in haemoglobin concentration. Of 89 patients presenting with femoral neck fractures 32 were on long-term aspirin therapy. Pre-operative aspirin ingestion did not significantly affect peri-operative blood loss, or change in haemoglobin concentration or haematocrit. However those patients taking aspirin pre-operatively had a significantly lower haemoglobin concentration and haematocrit and were more likely to be anaemic at presentation than those who were not receiving aspirin. Patients taking aspirin were also more likely to receive blood transfusion post-operatively.
