Higher Complication Rates In Patients Research Articles

Higher modified frailty index score is associated with 30-day postoperative complications following simultaneous bilateral total knee arthroplasty

BackgroundThere is no clear consensus regarding patient populations at highest risk for complications from simultaneous bilateral total knee arthroplasty (TKA). The purpose of this study was to determine whether the comorbidities comprising the modified Frailty Index (mFI) were correlated with poor outcomes following simultaneous bilateral TKA. MethodsFrom 2006 to 2019, patients undergoing bilateral TKA aged 50 years or older were identified in a national database. The 5-item mFI was calculated based on the presence of five comorbidities: diabetes, congestive heart failure, hypertension, chronic obstructive pulmonary disease, and dependent functional status. Chi-squared and multivariable regression analyses were used to evaluate the association of mFI scores with postoperative complications. ResultsThe study analyzed 8,776 patients with an average age of 65 years. After adjustment on multivariable regression analysis, compared to patients with a mFI score of 0, those with a score of 1 had an increased risk of pulmonary complication (OR 3.14; p = 0.011), renal problem (OR 12.86; p = 0.022), sepsis complication (OR 2.82; p = 0.024), postoperative transfusion (OR 1.19; p = 0.012), and non-home discharge (OR 1.17; p = 0.002).Patients with a score of 2 compared to 0 had similar complications when compared. These patients had an increased risk of cardiac complication (OR 4.84; p = 0.009) and prolonged hospital stay (OR 4.06; p < 0.001). ConclusionIncreased mFI scores were associated with significantly higher complication rates in patients undergoing simultaneous bilateral TKA compared to unilateral TKA. Our results can be used to identify which patients may need a staged bilateral TKA or preoperative optimization to safely undergo a simultaneous bilateral TKA.Level of Evidence: III.

Abdominal Hypertension after Abdominal Plication in Postbariatric Patients: The Consequence in the Postoperative Recovery.

Background Abdominoplasty with abdominal plication increases intra-abdominal pressure (IAP) and has been previously associated with limited diaphragmatic excursion and respiratory dysfunctions. Many factors found in abdominoplasties and among postbariatric patients predispose them to a higher occurrence. This study aims to evaluate the impact of abdominal plication among postbariatric patients, assess whether the plication increases their IAP, and analyze how these IAP correlate to their postoperative outcome. Methods This prospective study was performed on all patients who underwent circumferential Fleur-De-Lis abdominoplasty. For this intended study, the IAP was measured by an intravesical minimally invasive approach in three stages: after the initiation of general anesthesia, after a 10-cm abdominal wall plication and skin closure, and 24 hours after the procedure. Results We included 46 patients, of which 41 were female and 5 were male. Before the bariatric procedure, these patients had an average maximum weight of 121.4 kg and an average maximum body mass index of 45.78 kg/m 2 ; 7 were grade I obese patients, 10 were grade II, and 29 were grade III. Only three patients were operated on with a gastric sleeve and 43 with gastric bypass. We presented six patients with transitory intra-abdominal hypertension in the first 24 hours, all of them from the grade I obesity group, the highest presented was 14.3 mm Hg. We presented 15% (7/46) of complication rates, which were only four seroma and five dehiscence; two patients presented both seroma and wound dehiscence. Conclusion Performing a 10-cm abdominal wall plication or greater represents a higher risk for intra-abdominal hypertension, slower general recovery, and possibly higher complication rate in patients who presented a lower degree of obesity (grade I) at the moment of the bariatric surgery.

Comparison of safety and efficacy of one shot dilation vs. gradual dilation technique in supine percutaneous nephrolithotomy.

To compare the efficacy and safety of gradual dilation (GD) and one-shot dilation (OSD) techniques in patients who underwent supine percutaneous nephrolithotomy (PCNL). The data of 176 patients who underwent supine PCNL were reviewed. Eighty-seven patients who underwent OSD were defined as group 1, and 89 patients who underwent GD were defined as group 2. Both surgical techniques were compared with each other in terms of various parameters. Then, regression analysis of factors predicting stone-free status and complications in patients who underwent supine PNL were performed. Then, regression analysis of factors predicting success rate and complications in patients who underwent supine PNL were performed. No statistical difference was found in terms of stone-free rate, Clavien-Dindo complication grade and operation time. No statistical difference was found in terms of success rate, Clavien-Dindo complication grade and operation time. However, the fluoroscopy time was found to be significantly shorter in group 1 (p < 0.001). In the analysis of factors predicting stone-free status, the presence of calyceal stones, increased stone size and number were associated with a decrease in stone-free rate. In the analysis of factors predicting success, the presence of calyceal stones, increased stone size and number were associated with a decrease in success rate. Increased fluoroscopy and operation time, increased complication rates were found to be significantly associated with residual stone. Analysis of factors predicting complications found a higher complication rate in patients with low BMI and severe hydronephrosis. Increased complication was associated with increased time to nephrostomy removal and hospital stay, decrease in stone-free rate, decrease in Hb and increase in Cre value at the postoperative 24th hour. When comparing OSD and GD in patients undergoing supine PCNL, both techniques have similar stone-free and complication rates. When comparing OSD and GD in patients undergoing supine PCNL, both techniques have similar success and complication rates. Compared to GD, the OSD technique can be preferred primarily due to its shorter fluoroscopy time.

Mid-term results of total hip arthroplasty with subtrochanteric Z-osteotomy in Crowe type 3-4 developmental hip dysplasia

Background/aim Total hip arthroplasty (THA) is technically more difficult and has higher complication rates in patients with Crowe type 3–4 developmental dysplasia of the hip (DDH). Due to the difficulties and different treatment options, there is still no consensus on the optimal treatment. We aimed to evaluate the mid-term results of our patients who had undergone subtrochanteric femoral shortening Z-osteotomy.Materials and methods This study included 37 hips of 29 patients with the diagnosis of Crowe 3-4 DDH between June 2010 and December 2016 and who underwent femoral shortening Z-osteotomy with cementless total hip arthroplasty. Acetabular component was determined according to the patient’s age and functional capacity and all patients were operated with a posterior approach. Functional results, postoperative complications, Harris and visual analogue scale (VAS) scores were evaluated. Results The average Harris hip score was 41.3 ± 3.1 preoperatively and 84.7 ± 4.3 postoperatively (p < 0.05). The mean preoperative hip pain score on the VAS was 7.9 (range: 6–9) and this was significantly lower at the last follow-up (mean: 3.4; range: 2–4) (p < 0.05). The final mean limb-length discrepancy was 1.3 cm. The average amount of femoral shortening was 3.2 cm. Regarding complications, 3 (10.3%) patients had dislocations. These patients underwent closed reduction. Sciatic palsy developed in 1 (3.4%) patient. The patient was reoperated on for sciatic nerve dissection in the early period.Conclusion Subtrochanteric shortening Z-osteotomy combined with cementless total hip replacement can be considered an effective and successful method in selected patients with Crowe 3-4 coxarthrosis.

The Feasibility of Early Closure of Defunctioning Loop Ileostomy after Low Anterior Resection for Rectal Cancer

Background: The advantages of defuctioning loop ileostomy in some cases of rectal carcinoma is not questionable, but many patients experience serious stoma related complications and impaired quality of life. Early closure of the defunctioning ileostomy could mitigate these problem. Methods: This is a controlled randomized study done on 100 patients suffering of rectal cancer who had low anterior resection of the rectum and covering ileostomy at Menofiya University Hospital between April 2016 to august 2019. The patients were randomly divided (by closed envelope method) in two equal groups, Group A (Early group) and Group B (Late group). Results: As regards the pre-closure ileostomy complications: skin infection and maceration occurred in 4 pts. In early group and in 15 pts.in late group while dehydration and electrolyte imbalance occurred in 3 pts. In early group and in11 pts. In the late one, with both complications were significantly higher in late group (P value; 0.009 and 0,04 respectively). The health related quality of life was found to be higher in early group at 2 and 6 months than that in late group, but this did not yet reach significant difference, and at 12 month, the results were almost the same. Conclusion: Early ileostomy closure is safe, and not associated with higher complication rates in patients with an uncomplicated postoperative course and radiologically verified intact distal loopogram study.

Safety of early ileostomy closure: a systematic review and meta-analysis of randomized controlled trials.

Patients with a defunctioning ileostomy after rectal resection experience substantial ileostomy-related morbidity and decreased quality of life. Early reversal of the defunctioning ileostomy has been proposed as a method of mitigating these problems. We aimed to evaluate the safety of early ileostomy closure within 6 weeks. Randomized controlled trials investigating the safety of early ileostomy closure were identified through a systematic search and review of the current literature. Meta-analysis of the extracted outcome data was performed, and the methodological quality of the individual studies was assessed. The search identified six eligible studies yielding a total of 528 patients, with 269 in the early closure (EC) group and 259 in the standard closure (SC) group. Major complications in the EC group was 5.2% compared with 3.6% in the SC group (RR = 1.12, 95% CI 0.33-3.79). Anastomotic leakage in the EC group was 3.3% compared with 3.5% in the SC group (RR = 0.89, 95% CI 0.29-2.75). The meta-analysis resulted in no statistically significant differences between the groups in any of the primary or secondary outcomes. This review was not able to discern a statistically significant difference in postoperative complications when comparing early and standard ileostomy closure. The current literature indicates that early ileostomy closure is not associated with higher complication rates in patients with an uncomplicated postoperative course and radiologically verified intact distal anastomosis after index surgery.

Surgical Interventions for Cervical Radiculopathy without Myelopathy: A Systematic Review and Meta-Analysis.

The effectiveness of surgical interventions for cervical degenerative disorders has been investigated in multiple systematic reviews. Differences in study population (e.g., patients with myelopathy and/or radiculopathy) were often neglected. Therefore, the objective of this study was to investigate the effectiveness of surgical interventions for patients with symptoms of cervical radiculopathy without myelopathy by conducting a systematic review and meta-analysis based on randomized controlled trials (RCTs). A comprehensive systematic search was conducted in MEDLINE, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) to identify RCTs that investigated the effectiveness of surgical interventions using an anterior or posterior approach compared with other interventions for patients with pure cervical radiculopathy. Outcomes were success rates (Odom criteria, similar rating scales, or percentage of patients who improved), complication and reoperation rates, work status, disability (Neck Disability Index), and pain (arm and neck). The Cochrane risk-of-bias tool was used to assess the likelihood of the risk of bias. A random-effects model was used. Heterogeneity among study results (I2 ≥ 50% or p < 0.05) was explored by conducting subgroup analyses. Funnel plots were used to assess the likelihood of publication bias. A total of 21 RCTs were included, comprising 1,567 patients. For all outcomes, among all surgical techniques, only 1 pooled estimate showed a significant effect on success rate, which was in favor of anterior cervical discectomy with fusion compared with anterior cervical discectomy without an intervertebral spacer (p = 0.02; risk ratio [RR] = 0.87; 95% confidence interval [CI] = 0.77 to 0.98). Complication rates were higher when autologous bone graft from the iliac crest was used as an intervertebral spacer (p < 0.01; RR = 3.40; 95% CI = 1.56 to 7.43), related to donor-site morbidity. This meta-analysis demonstrated consistent results regarding clinical outcome for pure cervical radiculopathy among all studied interventions. Complication and reoperation rates were also similar, with the exception of higher complication rates in patients in whom autologous bone grafts were used. On the basis of clinical outcome and safety, there is no superior surgical intervention for pure cervical radiculopathy. Therapeutic Level I.

Reverse Shoulder Arthroplasty in Patients with Rheumatoid Arthritis: Early Outcomes, Pitfalls, and Challenges.

ObjectiveTo evaluate the early outcomes and risk factors of reverse shoulder arthroplasty (RSA) in patients with rheumatoid arthritis (RA).MethodsA retrospective study was performed on RA patients who had undergone RSA between January 2016 and January 2018. Preoperative glenohumeral joint damage was evaluated according to two radiographic classification systems. The severity of joint damage was estimated using Larsen's method, while the Levigne‐Franceschi method was used to assess the type of destruction. Further, we recorded intra‐ and postoperative complications. Visual Analogue Scale (VAS) was used to assess the degree of shoulder pain while shoulder function was evaluated with the American Shoulder and Elbow Surgeons (ASES) Shoulder Score. In addition, patients' subjective outcome and range of shoulder motion were recorded. Radiographs were taken and examined during the follow‐up period. Paired t‐test was used to determine the difference in measurement data between preoperative and the last follow‐up. VAS was analyzed using the Wilcoxon matched‐pairs signed‐rank test.ResultsA total of 14 patients with 14 shoulders were included. All the patients were female with an average age of 60.29 years (range, 49–71 years) at the time of surgery and an average RA disease duration of 24.57 years (range, 5–40 years). Seven of the 14 patients had a history of joint surgery related to RA. Meanwhile, 11 of the 14 shoulders showed glenoid bone defect, and eccentric reaming was performed intraoperatively to avoid base plate malposition. The mean follow‐up period for the 14 patients was 2.76 years (range, 2–4 years). The mean VAS decreased from a value of 5.71 ± 1.10 preoperatively to 1.36 ± 0.61 postoperatively (P < 0.001). On the contrary, the ASES score showed an increase from 33.93 ± 6.89 to 76.67 ± 5.23 (P < 0.001). An increase in active forward elevation, abduction, and external rotation with the arm in 90° of abduction from 85.71° ± 17.61°, 77.14° ± 19.43°, and 17.14° ± 10.97° to 126.43° ± 5.23°, 106.42° ± 11.72°, and 38.57° ± 14.57°, respectively, was observed (P < 0.001). Subjective outcome assessment showed that 13 of the 14 patients were very satisfied or satisfied with the operation, while one patient was uncertain due to co‐existing ipsilateral elbow lesion. Notably, one patient acquired a humeral periprosthetic fracture during the operation. In this study, no major complications such as periprosthetic joint infection and dislocation or implant loosening were observed. Further, no patients underwent revision for any reason at the end of the follow‐up.ConclusionsRSA could achieve good early outcomes without high complication rates in patients with RA. Glenoid bone defects and adjacent joints involvement were common in this patient group, which might increase the risk of surgery and affect postoperative satisfaction.

Smoking and bladder cancer: review of the recent literature.

This review summarizes the current knowledge regarding the relationship between smoking and bladder cancer (BCa), especially with respect to treatment outcomes for muscle and nonmuscle-invasive BCa (MIBC/NMIBC). PubMed/Medline databases were searched for recent reports investigating the association of smoking with BCa. Smoking is associated with an increased risk of recurrence in patients with NMIBC and may impair Bacillus Calmette-Guerin treatment efficacy. Moreover, smoking is associated with poor responses to neoadjuvant chemotherapy, poor survival outcomes and high complication rates in patients undergoing radical cystectomy. Smoking cessation mitigates these negative effects, especially. However, the amount of patient counselling provided regarding this important matter and patient knowledge regarding smoking and BCa risk are inadequate. Currently, the impact of secondhand smoke on BCa risk remains uncertain. Tobacco smoking is responsible for approximately half of BCa cases, and is associated with poor oncological outcomes for both NMIBC and MIBC. Despite smoking being a well known risk factor, counselling and knowledge in this area are insufficient. Appropriate smoking cessation interventions and patient information are required to improve patient health and optimize BCa survival.

Predicting Mortality Due to SARS-CoV-2: A Mechanistic Score Relating Obesity and Diabetes to COVID-19 Outcomes in Mexico.

BACKGROUNDThe SARS-CoV-2 outbreak poses challenge to healthcare systems due to high complication rates in patients with cardiometabolic diseases. Here, we identify risk factors and propose a clinical score to predict COVID-19 lethality, including specific factors for diabetes and obesity and its role in improving risk prediction.METHODSWe obtained data of confirmed and negative COVID-19 cases and their demographic and health characteristics from the General Directorate of Epidemiology of Mexican Ministry of Health. We investigated specific risk factors associated to COVID-19 positivity and mortality and explored the impact of diabetes and obesity on modifying COVID-19 related lethality. Finally, we built a clinical score to predict COVID-19 lethality.RESULTSAmong 177,133 subjects at May 18th, 2020, we observed 51,633 subjects with SARS-CoV-2 and 5,332 deaths. Risk factors for lethality in COVID-19 include early-onset diabetes, obesity, COPD, advanced age, hypertension, immunosuppression, and CKD; we observed that obesity mediates 49.5% of the effect of diabetes on COVID-19 lethality. Early-onset diabetes conferred an increased risk of hospitalization and obesity conferred an increased risk for ICU admission and intubation. Our predictive score for COVID-19 lethality included age ≥65 years, diabetes, early-onset diabetes, obesity, age <40 years, CKD, hypertension, and immunosuppression and significantly discriminates lethal from non-lethal COVID-19 cases (c-statistic=0.823).RESULTSHere, we propose a mechanistic approach to evaluate risk for complications and lethality attributable to COVID-19 considering the effect of obesity and diabetes in Mexico. Our score offers a clinical tool for quick determination of high-risk susceptibility patients in a first contact scenario.

Complication Rates During Endoscopic Microvascular Decompression Surgery Are Low With or Without Petrosal Vein Sacrifice

Endoscopic-microvascular decompression (E-MVD) is a well-described treatment for trigeminal neuralgia (TGN), but there has been debate on the safety of intraoperative sacrifice of the petrosal vein (PV) due to concern for subsequent venous insufficiency. Our objective was to investigate the risk of PV sacrifice during E-MVD in TGN and subsequent postoperative complications and pain outcomes. 5 five-year review yielded 201 patients who underwent MVD for TGN. PV sacrifice, vascular compressive anatomy, and postoperative complications attributable to venous insufficiency were analyzed. Preoperative and postoperative pain outcomes were analyzed. PV was sacrificed in 118 of 201 (59%) of patients, with 43 of 201 (21%) patients undergoing partial sacrifice versus 75 of 201 (37%) with complete sacrifice. No cases of venous infarction, cerebellar swelling, or fatal complications were noted in either cohort. Non-neurologic complications occurred in 1.69% (2 of 118) of patients with PV sacrifice and 0% (0 of 83) of patients with PV preservation. Neurologic deficits (facial palsy, conductive hearing loss, gait instability, memory deficit) occurred in equal proportions in PV preservation and sacrifice groups (2.41% vs. 1.69%) Overall, 87.3% (145 of 166) patients reported their pain as "very much improved" or "much improved" at 1 month, and no difference between groups was identified. This study did not find higher complication rates in patients undergoing petrosal vein sacrifice during E-MVD for trigeminal neuralgia. In this series where petrosal vein was sacrificed only 59% of the time, it appears to be a safe technique, but larger studies will be needed to determine true incidence of complications after PV sacrifice.

Abstract No. 500 Cryoprobe factors associated with higher complication rates in patients undergoing percutaneous image-guided liver tumor cryoablation

The goal of this study was to evaluate possible associations between cryoablation probe factors and high-grade adverse events (AE) in patients undergoing percutaneous image-guided hepatic tumor cryoablation. In this IRB-approved retrospective study, a total of 204 patients were studied. Inclusion criteria included (1) age>18 years, (2) pathology-proven hepatic malignancy, and (3) and image-guided hepatic cryoablation performed between October 1998 and December 2018. The standard cryoablation protocol utilized the SeedNet system (Galil Medical, Inc) and included two 15-minute freeze applications separated by a 10-minute thaw. Procedure-related AE were graded using the CTCAE grading system. High-grade postprocedural AE were defined as CTCAE grades 3 or higher. Chi-squared analysis and ANOVA analysis were used to assess for statistically significant differences for categorical variables and continuous variables, respectively. Univariate analysis was used to assess the clinical and technical factors associated with high-grade AE. Factors assessed included demographic data, tumor type, number of cryoablation probes used and probe insulation. A total of 204 patients met inclusion criteria (52% female, age range 29 to 91, mean 62.4). Average tumor diameter was 2.4 ± 1.1 cm (range, 0.4-5 cm). 25% of tumors were primary hepatic malignancies with the remaining consisting of metastatic hepatic lesions. Insulated probes were used in 50% of the cases. The mean number of probes used was 3.6 ± 2.7. We observed an overall 28% AE rate during the study period, the high-grade AE rate was 6%. There were a total of 22 grade 1, 24 grade 2, 8 grade 3 and 3 grade 4 AE. No grade 5 AE occurred. A higher number of cryoablation probes (OR = 1.42, P <0.001) and lack of probe insulation (OR = 5.1, P = 0.042) were associated with increased likelihood of high-grade AE. None of the other assessed factors were associated with high-grade AE. The use of insulated cryoablation probes and the use of fewer probes (when feasible) may reduce the likelihood of high-grade AE in patients undergoing hepatic cryoablation.

Longitudinal clinical outcomes after full-endoscopic lumbar discectomy for recurrent disc herniation after open discectomy

ObjectiveFull-endoscopic lumbar discectomy (FELD) is a minimally invasive surgical option for recurrent lumbar disc herniation (LDH). Nonetheless, patients’ clinical outcomes may be poorer after surgery for recurrent LDH than for primary LDH. Therefore, we compared patients’ longitudinal clinical outcomes after FELD for recurrent LDH or primary LDH. MethodsThe medical records of patients who underwent FELD for primary LDH (group A) or recurrent LDH (group B) were retrospectively reviewed. The inclusion criteria were: 1) single-level LDH or recurrent LDH at L4-5 or L5-S1, 2) age ≤60 years, 3) previous open discectomy (group B), and 4) ≥6 months of follow-up. In total, 244 patients (group A, 211; group B, 33) were included. Clinical outcomes (Oswestry Disability Index [ODI]; visual analogue pain score for the back and leg [VAS-B] and [VAS-L]) over 24 months of follow-up were compared between groups with a linear mixed-effects model. ResultsAll clinical outcomes significantly improved from pre-operation to 3 months postoperatively (p < 0.01), and the improvement was maintained for 24 months postoperatively in both groups. The clinical outcomes of groups A and B were not significantly different during 24 months follow-up (ODI, p = 0.94; VAS-B, p = 0.11; and VAS-L, p = 0.48). The reoperation rate was 3.3% in group A and 3.0% in group B, but the overall complication rate was higher in group B (9.8%) than in group A (6.6%). ConclusionThe longitudinal clinical outcomes after FELD for recurrent LDH may not be poor as feared. However, the higher complication rate in patients undergoing FELD for recurrent LDH should be noted.

The impact of preoperative biliary stenting in pancreatic cancer: A case-matched study from the German nationwide pancreatic surgery registry (DGAV StuDoQ|Pancreas)

Background/ObjectiveThe impact of preoperative biliary stenting (PBS) before pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) is controversial. MethodsPatients undergoing PD with or without PBS for PDAC were identified from the German DGAV-StuDoQlPancreas registry. The impact of PBS on perioperative complications was analyzed. Results1133 patients undergoing PD for PDAC were identified from the registry. After matching, 480 PBS patients vs. 480 patients without PBS were analyzed. Postoperative complications Clavien-Dindo classification (CDC) grade IIIa-IVb were higher in PBS patients (PBS 27% vs. no PBS 22%, p = 0.027). 320 PBS patients (66%) had no history of jaundice. In these patients, PBS was associated with higher morbidity. In contrast, PBS was not associated with higher complication rates in patients with history of jaundice. Serum bilirubin levels of 15 mg/dl and higher lead to more CDC IIIa-IVb (24% vs. 28%, p = 0.053) and higher mortality (3% vs. 7%, p < 0.001). PBS in patients with serum bilirubin levels of >15 mg/dl increased CDC IIa-IVb complications (21% vs. 50%, p = 0.001), mortality was equivalent. ConclusionMost PBS procedures were performed in patients with no history of jaundice and increased morbidity. Serum bilirubin levels >15 mg/dl lead to higher morbidity and mortality. PBS correlated with higher complication rates in these patients.

Prognostic risk factors for complications associated with tibiotalocalcaneal arthrodesis with a nail

BackgroundTibiotalocalcaneal (TTC) arthrodesis with a nail can be an effective salvage procedure for several foot and ankle pathologies, but has a relatively high complication rate. The purpose of this study is to investigate risk factors associated with complications after TTC arthrodesis with a nail. MethodsClinical and radiographic outcomes for 82 patients from 2012 to 2016 who underwent TTC arthrodesis with a nail were retrospectivelyevaluated to determine if patient or surgeon specific variables offered prognostic value in predicting negative outcomes. ResultsDiabetes, diabetic neuropathy, high (>2) American Society of Anesthesiologists (ASA) classification, and Charcot neuroarthropathy all were predictive of developing a nonunion in either the subtalar ortibiotalar joints (p<0.05). Diabetic neuropathy was predictive ofreoperation, and along with HbA1C >7.5 was also predictive of hardwarefailure. The odds ratio (OR) for diabetic neuropathy was 2.99 (p<0.05)for nonunion in the tibiotalar or subtalar joints, 3.46 (p<0.05) for reoperation,and 4.11 (p<0.05) for hardware failure. High ASAclassification had an odds ratio of 3.93 (p<0.05) for nonunion in the tibiotalar or subtalar joints as well. Diabetes had an odds ratio of 2.57 (p<0.05) for nonunion. ConclusionsPatients with diabetic neuropathy, Charcot neuroarthropathy, elevated HbA1C, and ASA classification >2 demonstrated a higher complication rate in patients undergoing TTC arthrodesis with a nail.

Vertebrectomy in metastatic spinal tumours: A 10 year, single-centre review of outcomes and survival

Metastatic disease to the vertebral column can cause spinal instability, neurological deterioration and pain. The present study was designed to provide insight into the cohort undergoing vertebrectomy for metastatic disease to the spinal column, assessing the associated morbidity, functional outcomes and survival. A retrospective review of 141 consecutive vertebrectomies for metastatic disease was undertaken. The procedures were performed between 2006 and 2016 at a single institution. Medical records were reviewed and data was obtained regarding primary malignancy, presenting symptoms, pre-operative chemotherapy or radiotherapy, Spinal Instability Neoplastic Score, neurological function, operative approach and duration, blood loss, transfusion requirement, complications, survival, delayed neurological deterioration and construct failure. Long-term follow-up data was available for 123 patients. Forty-two patients were alive at the time of review with a mean survival of 464 days. Post-operative neurological function was preserved or improved in 96.5% of patients. Five patients suffered a neurological deterioration post-operatively. The major complication rate was 19.8% with the most frequent complication being wound infection or dehiscence requiring revision. There were four inpatient deaths. Mean operative time was 240 min. Mean blood loss was 1490 mls. When assessing results by age, no significant difference with respect to complications, neurological outcomes or survival was demonstrated in patients over age 65. There was a significant reduction in survival and higher complication rates in patients who were non-ambulatory following vertebrectomy. Vertebrectomy is a safe and effective means of providing circumferential neural decompression and stabilization with an acceptable complication rate in patients with vertebral metastases, irrespective of age.

Abstract: Effects of Radiation on Risks and Patient-Reported Outcomes in Expander-Implant Reconstruction: Is There a “Best” Time to Radiate?

INTRODUCTION: The oncologic benefit of radiation therapy for node positive breast cancer is well-known. However, studies have also shown poorer aesthetic outcomes, lower satisfaction, and higher complication rates in patients undergoing breast reconstruction with post-mastectomy radiation therapy (PMRT), compared to non-radiated patients.1,2 The timing of radiation treatment in two-staged, expander-implant reconstruction, whether to radiate before or after expander-implant exchange, has been a subject of contention. Previous research attempting to answer this question has been limited by small sample sizes and single center designs. In the current study, we evaluated the effects of radiation timing on patient reported outcomes (PROs) and complications in patients undergoing immediate expander-implant reconstruction. METHODS: Patients receiving immediate expander-implant reconstruction and PMRT at 11 Mastectomy Reconstruction Outcomes Consortium (MROC) study sites were assessed preoperatively and two years following expander placement. Demographic and clinical data (age, BMI, diabetes, race, laterality, mastectomy type, extent of disease, acellular dermal matrix use, and chemotherapy) were collected. Patient-reported outcomes were assessed with BREAST-Q, PROMIS, and EORTC QLQ-BR23 surveys. Complications and reconstructive failures within two years were also recorded, with complications requiring reoperation or rehospitalization designated as “major”. Survey scores and complication rates were compared across cohorts using multivariate regressions, controlling for demographic and clinical variables. RESULTS: Of the 3120 patients recruited in the MROC study, 317 met inclusion criteria. Of those, 237 patients received radiation treatment before expander-implant exchange (TE-XRT), and 80 received radiation treatment after exchange (Implant-XRT). Controlling for covariates, radiation timing had no significant effects on PRO subscale scores at two years postoperatively. Compared with preoperative assessments, two year PRO scores were significantly lower in both cohorts for satisfaction with breast, physical well-being, and sexual well-being subscales of BREAST-Q (p < 0.05). In addition, for the TE-XRT cohort, the two year PRO scores were significantly lower in the body image subscale of EORTC as well (p < 0.05). Finally, timing of radiation had no significant effects on odds of overall complications, major complications or reconstructive failure. CONCLUSION: In this multicenter, prospective analysis, the timing of radiation (before or after exchange) appeared to have no significant effects on either PROs or complication risks in immediate expander-implant reconstruction. Regardless of radiation timing, two year measures of satisfaction and other PROs did not appear to return to preoperative levels among women undergoing immediate expander-implant reconstruction in conjunction with PMRT. These findings provide patients and providers with additional evidence for treatment decision-making.

Prognostic risk factors for complications associated with Tibiotalocalcaneal fusion with a nail

Category: Ankle Introduction/Purpose: Tibiotalocalcaneal (TTC) fusion with a nail is an effective salvage procedure for several foot and ankle pathologies, but it is associated with a relatively high complication rate and often performed on patients with multiple medical comorbidities. There is a paucity of literature that aids in predicting outcomes for patients undergoing TTC fusion with a nail. Methods: Clinical and radiographic outcomes for 82 patients from 2012-2016 who underwent TTC fusion with intramedullary nailing were retrospectively evaluated. Postoperative complications of nonunion, infection, reoperation, and hardware failure were included for comparison. Patient dependent variables and surgeon dependent variables were evaluated for association with these postoperative complications. Results: The overall complication rate for TTC fusion with a nail was 47/82 (57.3%). Diabetes (p=.049), diabetic neuropathy (p=.031), ASA classification (p=.005), and Charcot neuropathy (p=.003) were associated with nonunion of either the tibiotalar or subtalar joints in 29/82 (35.3%) patients. Diabetic neuropathy was associated with need for reoperation (p=.016) in 21/82 (25.6%) patients. Diabetic neuropathy (p=.022) and HbA1C &gt;7.5 (p=.047) was associated with hardware failure in 13/82 (15.9%) patients. The odds ratio (OR) for diabetic neuropathy was 2.99 (p=0.038) for nonunion in the tibiotalar or subtalar joints, 3.46 (p=0.021) for re-operation, and 4.11 (p=0.035) for hardware failure. High ASA classification had an odds ratio of 3.93 (p=0.006) for nonunion in the tibiotalar or subtalar joints. Conclusion: Patients with diabetic neuropathy, Charcot neuropathy, elevated HbA1C, and higher ASA classification demonstrated a higher complication rate in patients undergoing TTC fusion with a nail.

Peripherally Inserted Central Venous Catheters Are Associated With High Complication Rates in Patients With Inflammatory Bowel Disease

Introduction: Patients with inflammatory bowel disease (IBD) develop perforating complications and utilize total parenteral nutrition (TPN) as a form of treatment. Central venous catheter (CVC) placement is needed to administer TPN and/or antibiotics. The aim of this study was to identify factors associated with complications in IBD patients undergoing CVC placement. Methods: IBD patients that underwent long-term (>14 days) CVC placement from 2004 until 2013 were identified. Clinical information was extracted from a data repository and review of the medical record. CVC were categorized as ports, Hickman catheters (HC), and peripherally inserted central catheters (PICC). Modifications including antiseptic coatings, cuffs, tunneling and antibiotic/anticoagulant flushes were recorded. Development of CVC-related complications was recorded. Results: 93 patients underwent CVC placement. 74% were Caucasian, 70% were women, and 83% had CD. 47, 36, and 17% of CD patients had ileocolonic, ileal, and colonic disease location. 28% had perianal disease and 74% had perforating behavior. 77% of UC patients had pancolitis. 48 underwent HC, 45 underwent PICC, and none had a port. 24 (26%) developed a complication, including 20 line infections, 3 thrombotic events, and 1 septic thrombosis. 2 patients died. 96% of patients with complications underwent CVC placement to receive TPN. 19 (31%) patients undergoing PICC placement had a complication compared to 5 (19%) patients undergoing HC placement (p < 0.18). Modifications to CVC placement did not decrease the rate of CVC-complications. Patients with an abscess or treated with antibiotics at admission and those that developed post-operative infections were more likely to develop complications (p < 0.05). Methotrexate (MTX) was associated with complications (p < 0.05); however the number of patients treated with MTX was small (n=6). 13 (72%) patients with a history of MRSA, VRE, or CRE developed complications compared to 18% of patients without resistant bacteria (p=0.03). A history of prior CVC-related infection was associated with complications (56 vs. 19%, p=0.001). Patients with peripheral vascular disease and connective tissue diseases were more likely to develop complications (p=0.02). Conclusion: Providers should advocate strongly for HC placement if considering long term CVC use in IBD patients, especially if concurrent infection, prior CVC-related infection, or a history of resistant organisms is present.

Lead Burden as a Factor for Higher Complication Rate in Patients With Implantable Cardiac Devices

Lead revisions have increased over the last decade. Patients who do not undergo lead extraction face an increased lead burden. Consequences of increased lead burden have not been fully defined. We sought to characterize the complication rate and outcomes in patients with sterile redundant leads.
