Full Text Available Objective: To Test the efficacy of single preoperative dose of Cefotaxime 1gm and Metronidazole 500mg in reducing the surgical site infections (SSIs after open appendectomy in patients with non-complicated appendicitis (NCA Place and Duration of Study: Al Hilla General Teaching Hospital, Babel Governorate-Iraq, from January 2013 to January 2014. Patients & Methods: 100 patients, who underwent appendectomy for NCA and fulfilled the selection criteria, were randomized into two groups. The patients in group A received a single dose of pre-operative antibiotics (Cefotaxime sodium and metronidazole, while the group B patients received three more dose of the same antibiotics postoperatively. Patients of both groups were followed-up for 30 days to assess the postoperative infective complications. Results: Group A had 48, while group B comprised of 52 patients. The groups were comparable in the baseline characteristics. Statistically, P value in rates of SSIs between both the groups was 0.9182. None of the patients developed intra-abdominal collection. Conclusion: Single dose of pre-operative antibiotics (Cefotaxime and metronidazole was sufficient in reducing the SSIs after appendectomy for NPA. Postoperative antibiotics did not add an appreciable clinical benefit in these patients.

Unrelieved postoperative pain may impair rehabilitation, compromise functional outcomes, and lead to patient dissatisfaction. Preemptive multimodal analgesic techniques may improve outcomes after surgery. We hypothesized that patients using preoperative cryotherapy plus a standardized postoperative treatment plan will have lower pain scores and require less pain medication compared with patients receiving a standardized postoperative treatment plan alone after arthroscopically assisted anterior cruciate ligament reconstruction (ACLR). A total of 53 consecutive patients undergoing arthroscopically assisted ACLR performed by one of seven surgeons were randomly assigned to one of two groups. Group 1 received no preoperative cryotherapy and group 2 received 30 to 90 minutes of preoperative cryotherapy to the operative leg using a commercial noncompressive cryotherapy unit. Visual analog scale pain scores and narcotic use were recorded for the first 4 days postoperatively. Total hours of cold therapy and continuous passive motion (CPM) use and highest degree of flexion achieved were recorded as well. Group 1 consisted of 26 patients (15 allograft Achilles tendon and 11 autograft bone patellar tendon bone [BPTB]), and group 2 consisted of 27 patients (16 allograft Achilles tendon and 11 autograft BPTB). Group 2 patients reported less pain (average 1.3 units, p cryotherapy, hours of CPM use, or maximum knee flexion achieved. Complications did not occur in either group. This is the first report we are aware of showing the postoperative effects of preoperative cryotherapy. Our results support the safety and efficacy of preoperative cryotherapy in a multimodal pain regimen for patients undergoing ACL reconstruction.

To study preoperative HBV-DNA negative HBV-related hepatocellular carcinoma (HCC) which was reactivated after surgery and could influence liver function and HCC recurrence. Patients were divided into two groups according to preoperative antiviral therapy status. The control group comprised of 102 preoperative HBV-DNA-negative patients who had not undergone antiviral therapy before surgery. In the treatment group, all HBV-DNA-negative patients (n=63) received entecavir 3-5 days before surgery and for 12 months after surgery. Patients were followed-up regularly, during the preoperative period, and at 1, 3, 6, 12, 18, 24, 30 and 36 months postoperatively. The data for the two groups were analyzed including the level of HBV-DNA and HBV-DNA activation; liver function; 1-, 2- and 3-year survival rate; cumulative survival time; and tumor recurrence. Liver function in the treatment group was better than that of the control group12 months after surgery. Compared to the control group, total bilirubin in the treatment group was significantly better at 6 and 12 months after surgery (pHBV-DNA activation while there were 13 cases (12.75%) with HBV-DNA activation in the control group (pHBV-related HCC with negative HBV-DNA is beneficial to liver function, coagulation function, disease control, prevention of tumor recurrence, improvement of patient quality of life, reduces the death rate and prolongs survival duration.

Full Text Available Endale Gebreegziabher Gebremedhn, Vidhya Nagaratnam Department of Anesthesia, School of Medicine, Gondar College of Medicine and Health Sciences, University of Gondar, Gondar, Ethiopia Background: The evaluation of patient satisfaction is a core aspect of the continuous quality improvement in anesthesia service that can be affected by the preoperative anesthetist visit. This visit enables the anesthetist to know about the patient's general health status and the nature of surgery, to choose the type of anesthesia, and to discuss perioperative complications and their management with the patient. Patients have sometimes complained about the information given during the preoperative anesthetic evaluation in the University of Gondar teaching and referral hospital. The aim of this study was to determine the level of patient satisfaction with the preoperative anesthetist visit. Methods: A cross-sectional study was conducted from February 15 to April 15, 2013. All consecutive elective patients who were operated upon under anesthesia during the study period were interviewed 24 hours after operation. A pretested questionnaire and checklists, which were developed based on the hospital's anesthetic evaluation sheet, were used for data collection. Results: A total of 116 elective patients were operated upon under anesthesia during the study period. Of these, 102 patients were included in our study, with a response rate of 87.9%. Anesthetists introduced themselves to ~24% patients; provided information about anesthesia to ~32%, postoperative complications to ~21%, postoperative analgesia to ~18, and postoperative nausea and vomiting to ~21%; and spent adequate time with ~74%. Patients' questions were answered by the anesthetist in ~65% of cases, and ~65% of patients had reduced anxiety after the anesthetist visit. The patients' overall satisfaction with the preoperative anesthetist visit was ~65%. Conclusion and recommendation: Patient satisfaction with the

Patients (176) with potentially operable squamous cell carcinoma or adenocarcinoma of middle or lower thirds of oesophagus were randomly assigned to preoperative radiotherapy or surgery alone. Patients assigned to the radiotherapy arm received 20 Gy in 10 treatments over 2 weeks, using parallel opposed 4 MV beams. The preoperative radiotherapy was not associated with any significant acute morbidity or any increase in operative complications. The median survival of the overall group of 176 patients was 8 moths, and the 5-year survival was 13%. There was no significant difference in the survival of the 90 patients who received preoperative radiotherapy and the 86 who were managed by surgery alone. Proportional hazards analysis identified lymph node involvement, high tumor grade and male sex as significant adverse prognostic features, but the treatment option assigned had no prognostic significance. It was concluded that low dose preoperative radiotherapy offered no advantage over surgery alone. (author). 9 refs.; 3 figs.; 6 tabs

To investigate serum carcinoembryonic antigen (CEA) as a prognostic factor for rectal cancer patients receiving pre-operative chemoradiotherapy (CRT). Between 2000 and 2009, 138 patients with advanced rectal cancer receiving CRT before surgery at our hospital were retrospectively classified into 3 groups: pre-CRT CEA <6 ng/ml (group L; n = 87); pre-CRT CEA ≥ 6 ng/ml and post-CRT CEA <6 ng/ml (group H-L; n = 32); and both pre- and post-CRT CEA ≥ 6 ng/ml (group H-H; n = 19). CEA ratio (defined as post-CRT CEA divided by pre-CRT CEA), post-CRT CEA level and other factors were reviewed for prediction of pathologic complete response (pCR). Five-year disease-free survival (DFS) was better in groups L (69.0%) and H-L (74.5%) than in group H-H (44.9%) (p = 0.024). Pathologic complete response was observed in 19.5%, 21.9% and 5.3% of groups L, H-L and H-H respectively (p = 0.281). Multivariate analysis showed that ypN stage and pCR were independent prognostic factors for DFS and that post-CRT CEA level was independently predictive of pCR. As a whole, post-CRT CEA <2.61 ng/ml predicted pCR (sensitivity 76.0%; specificity 58.4%). For those with pre-CRT CEA ≥6 ng/ml, post-CRT CEA and CEA ratio both predicted pCR (sensitivity 87.5%, specificity 76.7%). In patients with pre-CRT serum CEA ≥6 ng/ml, those with “normalized” CEA levels after CRT may have similar DFS to those with “normal” (<6 ng/ml) pre-CRT values. Post-CRT CEA level is a predictor for pCR, especially in those with pre-CRT CEA ≥6 ng/ml

Full Text Available Previous studies addressing preoperative steroid treatment have revealed that control of myasthenia gravis (MG with steroids prior to surgery appeared to stabilize postoperative status. The purpose of our study was to clarify the clinical benefits of the preoperative programmed high-dose steroid treatment on the long-term outcomes of MG patients. We retrospectively reviewed the records of 171 MG patients who were followed up after undergoing thymectomy in our hospital between 1988 and 2006. One hundred and thirteen patients in the programmed treatment group had received preoperative steroid treatment, while 58 patients received no steroid treatment during the preoperative period. Clinical remission, which was defined as the achievement of the modified pharmacologic remission (PR for at least 1 year, and clinical benefits were compared between the two groups. With regard to the remission after thymectomy, Kaplan-Meier life-table curves for patients in the preoperative steroid treatment group versus those for patients in the no steroid preoperative treatment group revealed a significantly higher probability of the PR in the preoperative steroid treatment group (log-rank test, P<0.01. This study might be the first, as per our knowledge, to indicate that preoperative programmed high-dose steroid treatment has long-term beneficial effects for MG patients.

Preoperative MRI of the breasts has been proven to be the most sensitive imaging modality in the detection of multifocal or multicentric tumor manifestations as well as simultaneous contralateral breast cancer. The aim of the presented retrospective study was to evaluate the benefit of preoperative MRI for patients with breast cancer. Preoperative MRI performed in 121 patients (group A) were compared to 225 patients without preoperative MRI (group B). Patients of group A underwent contrast-enhanced MR imaging of the breast using a 2D FLASH sequence technique (TR/TE/FA 336 ms/5 ms/90diam.; 32 slices of 4-mm thickness, time of acquisition 1:27 min, contrast agent dosage 0.1 mmol Gd-DTPA/kg bw). All patients had histologically verified breast cancer and follow-up for more than 20 months (mean time group A: 40.3 months, group B: 41 months). Both groups received the same types of systemic treatment after breast conserving surgery. The in-breast tumor recurrence rate in group A was 1/86 (1.2%) compared to 9/133 (6.8%) in group B. Contralateral carcinoma were detected within follow-up in 2/121 (1.7%) in group A vs. 9/225 (4%) in group B. All results were statistically significant (P<0.001). Based on these results, preoperative MRI of the breasts is recommended in patients with histopathologically verified breast cancer for local staging

Carroll, Jennifer K

2012-01-01

Prevention of preoperative anxiety with anxiolytic premedication is associated with improved preoperative outcomes in surgical patients. The objective of the authors\\' study was to evaluate the percentage of surgical patients that are prescribed premedication for preoperative anxiety before their anticipated surgical procedure. A prospective study was carried out by theatre nursing staff in the theatre reception bay of a university teaching hospital. A questionnaire was designed to record the number of patients that described symptoms consistent with preoperative anxiety. The number of patients that had been offered anxiolytic premedication for preoperative anxiety was also recorded. Consent was obtained from 115 consecutive surgical patients (male, n=52; female, n=63). Of these, 66% (n=76) reported anxiety before their surgical procedure (male: n=27, female: n=49). Premedication with a low-dose benzodiazepine was prescribed by an anaesthetist in 4% of cases (n=5). Patients that received premedication preoperatively reported effective relief of their anxiety symptoms This study demonstrates that preoperative patient anxiety is highly prevalent. The authors\\' findings suggest that premedication with anxiolytic pharmacological therapy may be an underused therapeutic resource for managing preoperative patient anxiety.

Purpose: To evaluate the local control rates, survival rates, and patterns of failure for esophageal cancer patients receiving preoperative concurrent chemotherapy and hyperfractionated radiotherapy followed by esophagectomy. Methods and Materials: From May 1993 through January 1997, 94 patients with resectable esophageal cancers received continuous hyperfractionated radiation (4,800 cGy/40 fx/4 weeks), with concurrent FP chemotherapy (5-FU 1 g/m 2 /day, days 2-6, 30-34, CDDP 60 mg/m 2 /day, days 1, 29) followed by esophagectomy 3-4 weeks later. If there was evidence of disease progression on preoperative re-evaluation work-up, or if the patient refused surgery, definitive chemoradiotherapy was delivered. Minimum follow-up time was 2 years. Results: All patients successfully completed preoperative treatment and were then followed until death. Fifty-three patients received surgical resection, and another 30 were treated with definitive chemoradiotherapy. Eleven patients did not receive further treatment. Among 91 patients who received clinical reevaluation, we observed 35 having clinical complete response (CR) (38.5%). Pathologic CR rate was 49% (26 patients). Overall survival rate was 59.8% at 2 years and 40.3% at 5 years. Median survival time was 32 months. In 83 patients who were treated with surgery or definitive chemoradiotherapy, the esophagectomy group showed significantly higher survival, disease-free survival, and local disease-free survival rates than those in the definitive chemoradiation group. Conclusion: Preoperative chemoradiotherapy in this trial showed improved clinical and pathologic tumor response and survival when compared to historical results. Patients who underwent esophagectomy following chemoradiation showed decreased local recurrence and improved survival and disease-free survival rates compared to the definitive chemoradiation group

Elevated preoperative levels of alkaline phosphatase (ALP) in patients with refractory secondary hyperparathyroidism are correlated with postoperative hypocalcemia and mortality. The aim of this study was to identify the predictors of preoperative ALP in patients with secondary hyperparathyroidism. From April 2012 to December 2015, 220 patients with refractory secondary hyperparathyroidism undergoing total parathyroidectomy without autotransplantation were reviewed. A total of 164 patients presented with elevated preoperative ALP. Univariate analysis showed that patients with elevated ALP were significantly younger. The elevated ALP group had significantly higher levels of preoperative parathyroid hormone (PTH), lower preoperative serum calcium, higher preoperative phosphorus, lower postoperative hypocalcemia, and a longer hospital stay. Logistic regression analysis showed that elevated preoperative PTH was a significant independent risk factor for elevated preoperative ALP (P = 0.000), and its value of 1624 pg/mL was the optimal cutoff point. Factors predictive of elevated preoperative ALP in patients with secondary hyperparathyroidism include preoperative PTH. Earlier surgery, aggressive calcium supplementation, and more careful or aggressive postoperative care for high-risk patients are needed.

2016-12-01

Nurse-led preoperative assessment clinics (POAC) have been introduced in different specialty areas to assess and prepare patients preoperatively in order to avoid last-minute surgery cancellations. Not all patients are referred to POACs before surgery, and the benefits of nurse-led POACs are not well documented in Hong Kong. The purpose of this systemic review was to identify the best available research evidence to inform current clinical practice, guide health care decision making and promote better care. The Joanna Briggs Institute (JBI) approach for conducting systematic review of quantitative research was used. Data bases searched included all published and unpublished studies in Chinese and English. All studies with adult patients who required elective orthopaedic surgery e.g. total knee replacement, total hip replacement, reduction of fracture or reconstruction surgery etc. in a hospital or day surgery center and attended a nurse-led POAC before surgery were included. Ten studies were critically appraised. Results showed that nurse-led POACs can reduce surgery cancellation rates. These studies suggested a reduction in the rate of postoperative mortality and length of hospital stay. In addition, the level of satisfaction towards services provided was significantly high. Although POACs are being increasingly implemented worldwide, the development of clinical guidelines, pathways and protocols was advocated. The best available evidence asserted that nurses in the POAC could serve as effective coordinators, assessors and educators. The nurse-led practice optimized patients' condition before surgery and hence minimized elective surgery cancellations. Copyright © 2016 American Society of PeriAnesthesia Nurses.

To elucidate the proper length and prognostic value of resection margins in rectal cancer patients who received preoperative chemoradiotherapy (CRT) followed by curative total mesorectal excision (TME). A total of 1476 rectal cancer patients staging cT3-4N0-2M0 were analyzed. All patients received radiation dose of 50.4 Gy in 28 fractions with concurrent 5-fluorouracil or capecitabine. Total mesorectal excision was performed 4 to 8 weeks after radiation therapy. The recurrence-free survival (RFS) at 5 years showed a significant difference between 3 groups: patients with circumferential resection margin (CRM) ≤1 mm, CRM 1.1 to 5 mm, and CRM >5 mm (46.2% vs 68.6% vs 77.5%, P5 mm. Distal resection margin (≤5 vs >5 mm) did not show any significant difference in cumulative incidence of locoregional recurrence (P=.310) and distant metastasis (P=.926). Rectal cancer patients with CRM ≤1 mm are a high-risk group, with the lowest RFS. Patients with CRM 1.1 to 5 mm may be at intermediate risk, with moderately increased distant recurrence. Distal resection margin was not significantly associated with RFS in rectal cancer after neoadjuvant CRT and total mesorectal excision. Copyright © 2017 Elsevier Inc. All rights reserved.

Growing evidence supports the use of multimedia presentations for informing patients. Therefore, we supported preoperative education by adding a multimedia tool and examined the effects in a randomized controlled trial. We randomized German-speaking patients scheduled for radical prostatectomy at our center to receive either a multimedia-supported (MME) or a standard education (SE). Outcomes were measured in a structured interview. Primary outcome was patient satisfaction. In addition, we applied validated instruments to determine anxiety and measures of decision-making. Results were given by mean and standard deviation. For comparison of groups we used t test and chi-square test. For an explorative analysis we applied multivariate logistic regression. We randomized 203 patients to receive MME (n=102) or SE (n=101). Complete satisfaction with preoperative education was more frequent in the MME group (69 vs 52%, p=.016) and patients after MME reported more questions (5.7 vs 4.2, p=.018). There was no difference concerning the duration of talks and the number of recalled risks. However, perceived knowledge was higher after MME (1.3 vs 1.6, p=.037). Anxiety and measures of decision-making were comparable. Patients judged the multimedia tool very positive, and 74% of the MME group thought that their preoperative education had been superior to SE. Multimedia support should be considered worthwhile for improving the informed consent process before surgery (www.germanctr.de; DRKS00000096).

Preoperative radiotherapy was used in the management of selected patients with cancer of the lung or trachea who might subsequently require segmental resection of bronchus or trachea and reconstruction by primary anastomosis. This study was designed to determine the effects of varying dosages of preoperative irradiation on anastomotic healing. Two rings were resected from the cervical trachea of 20 dogs following irradiation with varying doses of cesium. There were no important adverse effects on healing of the trachea or adjacent organs in dogs receiving up to 3,500 rads. All dogs receiving a higher dose than this developed some anastomotic stenosis, which was severe in 6 of 8 animals. Similar adverse effects were observed in 2 patients managed by preoperative radiotherapy (4,000 rads in three weeks) and tracheal resection with primary anastomosis

Thyroidectomy is performed for hyperthyroidism on patients who do not respond to or are not compliant with medical therapy and in patients with very large goiters causing compressive symptoms. All thyrotoxic patients undergoing thyroidectomy usually are first treated with anti-thyroid drugs to normalize free thyroid hormone levels and render them euthyroid before surgery in order to prevent complications particularly thyroid storm and circulatory collapse. In this case series, we describe the clinical outcome during the perioperative (thyroidectomy) period of three severely hyperthyroid patients, two females and one male, with ages ranging from 13 to 38 years. All patients had grade III goiter, and only one had exophthalmos. The mean duration of goiter was 3.6 years. All of them were given preoperative treatment consisting of propylthiouracil (PTU) at 450-600 mg/day; iodone, 3 tablets daily and propranolol at 30-120 mg/day for one month. All of them had normalized preoperative thyroid function tests. In addition to the preoperative medications mentioned above, all three patients received radioactive iodine therapy before surgery. The first two patients received relatively low doses of 8.0 and 7.5 mCi of I-131 respectively. Unfortunately the first patient had supraventricular tachycardia (SVT), post skin cutting and the other one went into thyroid storm. The third patient who received a cumulative dose of 23.5 mCi of I-131 before surgery had an uneventful postoperative course. It is concluded that normalization of thyroid hormone parameters, especially free T4 is not sufficient for an uneventful and uncomplicated peri-thyroidectomy period in severely hyperthyroid patients with large goiters. Effective radioactive iodine therapy might prove to be helpful in inducing thyroid tissue fibrosis, thus leading to true clinical euthyroidism and excellent clinical course postoperatively. (author)

Aim: To determine when preoperative breast MRI will not be more informative than available breast imaging and can be omitted in patients eligible for breast conserving therapy (BCT). Methods: We performed an MRI in 685 consecutive patients with 692 invasive breast tumors and eligible for BCT based on conventional imaging and clinical examination. We explored associations between patient, tumor, and conventional imaging characteristics and similarity with MRI findings. Receiver operating characteristic (ROC) analysis was employed to compute the area under the curve (AUC). Results: MRI and conventional breast imaging were similar in 585 of the 692 tumors (85%). At univariate analysis, age (p < 0.001), negative preoperative lymph node status (p = 0.011), comparable tumor diameter at mammography and at ultrasound (p = 0.001), negative HER2 status (p = 0.044), and absence of invasive lobular cancer (p = 0.005) were significantly associated with this similarity. At multivariate analysis, these factors, except HER2 status, retained significant associations. The AUC was 0.68. Conclusions: It is feasible to identify a subgroup of patients prior to preoperative breast MRI, who will most likely show similar results on conventional imaging as on MRI. These findings enable formulation of a practical consensus guideline to determine in which patients a preoperative breast MRI can be omitted.

Aim: To determine when preoperative breast MRI will not be more informative than available breast imaging and can be omitted in patients eligible for breast conserving therapy (BCT). Methods: We performed an MRI in 685 consecutive patients with 692 invasive breast tumors and eligible for BCT based on conventional imaging and clinical examination. We explored associations between patient, tumor, and conventional imaging characteristics and similarity with MRI findings. Receiver operating characteristic (ROC) analysis was employed to compute the area under the curve (AUC). Results: MRI and conventional breast imaging were similar in 585 of the 692 tumors (85%). At univariate analysis, age (p < 0.001), negative preoperative lymph node status (p = 0.011), comparable tumor diameter at mammography and at ultrasound (p = 0.001), negative HER2 status (p = 0.044), and absence of invasive lobular cancer (p = 0.005) were significantly associated with this similarity. At multivariate analysis, these factors, except HER2 status, retained significant associations. The AUC was 0.68. Conclusions: It is feasible to identify a subgroup of patients prior to preoperative breast MRI, who will most likely show similar results on conventional imaging as on MRI.

Whereas the impact of magnetic resonance imaging (MRI) of the breast on the surgical management of breast cancer patients is well documented, less is known about its effect on health care costs. This study aimed to evaluate whether MRI use for women with invasive lobular carcinoma (ILC) significantly changes the cost of care. Patients with ILC were recruited to a prospective registry study of breast MRI. Women who met the same inclusion criteria but had not undergone breast MRI were retrospectively identified for comparison. A micro-costing analysis using institutional billing records was conducted. Nonparametric bootstrapping was used to compare the unadjusted cost differences between the patients receiving MRI and those receiving no MRI. Of the patients in this study, 51 had preoperative MRI, and 60 did not. Method of diagnostic biopsy, disease stage, oncologic procedure, and rates of contralateral prophylactic mastectomy were similar between the two groups. The patients in the MRI group were younger (median age 55 vs. 64 years; p = 0.01) and more likely to undergo reconstruction (45.1 vs. 25 %; p = 0.03). The median costs of care were significantly higher in the MRI group ($24,781 vs. $18,921; p 1; p < 0.01), and use of reconstruction (p < 0.01). Preoperative breast MRI increases the median total cost of care per patient. However, the contribution to the overall cost of care is modest compared with the cost of other interventions.

The aim of this study was to determine the clinical utility of routine preoperative pelvic and abdominal computed tomography (CT) examinations in patients with endometrial cancer (EC). We retrospectively reviewed records from patients with EC who underwent a preoperative endometrial biopsy and had surgery at our institution from January 1999 through December 2008. In the subset with an abdominal CT scan obtained within 3 months before surgery, we evaluated the clinical utility of the CT scan. Overall, 224 patients (18%) had a preoperative endometrial biopsy and an available CT scan. Gross intra-abdominal disease was observed in 10% and 20% of patients with preoperative diagnosis of endometrioid G3 and type II EC, respectively, whereas less than 5% of patients had a preoperative diagnosis of hyperplasia or low-grade EC. When examining retroperitoneal findings, we observed that a negative CT scan of the pelvis did not exclude the presence of pelvic node metastasis. Alternately, a negative CT scan in the para-aortic area generally reduced the probability of finding para-aortic dissemination but with an overall low sensitivity (42%). However, the sensitivity for para-aortic dissemination was as high as 67% in patients with G3 endometrioid cancer. In the case of negative para-aortic nodes in the CT scan, the risk of para-aortic node metastases decreased from 18.8% to 7.5% in patients with endometrioid G3 EC. Up to 15% of patients with endometrioid G3 cancer had clinically relevant incidental findings that necessitated medical or surgical intervention. In patients with endometrioid G3 and type II EC diagnosed by the preoperative biopsy, CT scans may help guide the operative plan by facilitating preoperative identification of gross intra-abdominal disease and enlarged positive para-aortic nodes that are not detectable during physical examinations. In addition, CT may reveal other clinically relevant incidental findings.

Preoperative radiochemotherapy (RCT) with 5-FU or capecitabine is the standard of care for patients with locally advanced rectal cancer (LARC). Preoperative RCT achieves pathological complete response rates (pCR) of 10-15%. We conducted a single arm phase II study to investigate the feasibility and efficacy of addition of bevacizumab and oxaliplatin to preoperative standard RCT with capecitabine. Eligible patients had LARC (cT3-4; N0/1/2, M0/1) and were treated with preoperative RCT prior to planned surgery. Patients received conventionally fractionated radiotherapy (50.4 Gy in 1.8 Gy fractions) and simultaneous chemotherapy with capecitabine 825 mg/m 2 bid (d1-14, d22-35) and oxaliplatin 50 mg/m 2 (d1, d8, d22, d29). Bevacizumab 5 mg/kg was added on days 1, 15, and 29. The primary study objective was the pCR rate. 70 patients with LARC (cT3-4; N0/1, M0/1), ECOG < 2, were enrolled at 6 sites from 07/2008 through 02/2010 (median age 61 years [range 39–89], 68% male). At initial diagnosis, 84% of patients had clinical stage T3, 62% of patients had nodal involvement and 83% of patients were M0. Mean tumor distance from anal verge was 5.92 cm (± 3.68). 58 patients received the complete RCT (full dose RT and full dose of all chemotherapy). During preoperative treatment, grade 3 or 4 toxicities were experienced by 6 and 2 patients, respectively: grade 4 diarrhea and nausea in one patient (1.4%), respectively, grade 3 diarrhea in 2 patients (3%), grade 3 obstipation, anal abscess, anaphylactic reaction, leucopenia and neutropenia in one patient (1.4%), respectively. In total, 30 patients (46%) developed postoperative complications of any grade including one gastrointestinal perforation in one patient (2%), wound-healing problems in 7 patients (11%) and bleedings in 2 patients (3%). pCR was observed in 12/69 (17.4%) patients. Pathological downstaging (ypT < cT and ypN ≤ cN) was achieved in 31 of 69 patients (44.9%). All of the 66 operated patients had a R0 resection

Fifteen patients undergoing gastric bypass surgery for morbid obesity received preoperatively a standard crystalline amino acid solution containing 15.6% branched-chain amino acids. During the first five postoperative days, the patients were randomized to receive one of three amino acid solutions of different branched-chain amino acid content. Whole-body amino acid appearance and oxidation were estimated using a continuous intravenous infusion of L-(U- 14 C)-tyrosine preoperatively and on the third postoperative day. This study suggests that an adequate nitrogen intake of a balanced amino acid mixture, as well as a solution enriched with branched-chain amino acids, maintains protein homeostasis and supports protein synthesis similarly in well-nourished patients following major abdominal surgery. A diet containing only branched-chain amino acids in isomolar ratios was as effective at maintaining protein retention and whole-body protein synthesis and albumin renewal postoperatively when compared with a standard amino acid formula

To compare the technical aspects of Wilms' tumour (WT) surgery in patients with and without pre-operative chemotherapy. Patients of WT, presenting between January 1999 and December 2001, were treated, using the NWTSG protocol, with primary surgery (group I). Between January 2001 and December 2004, WT patients were treated according to SIOP protocol, with pre-operative chemotherapy followed by surgery (group II). Volume reduction with chemotherapy, duration of surgery, rupture of tumour, extent of excision, adherence and damage to surrounding structures, blood loss, complications, stay in hospital and event-free survival (EFS) were compared in the two groups. Out of 22 patients in group I, 19 (86.4%) underwent primary surgery. Of the 23 patients in group II, 21 (91.3%) received pre-operative chemotherapy followed by surgery. Average volume reduction in this group was 54% with chemotherapy. Difference in duration of surgery and blood loss was significantly low in group II (p=0.003 and p<0.001, respectively). In group I, rupture (6 vs 2), adherence (14 vs 10) and damage to surrounding structures (5 vs 2) were more. Complete macroscopic excision was possible in 90.5% of WT in group II as compared to 73.7% in group I. Immediate postoperative complications and length of hospital stay were similar in both groups. There was no difference in EFS. (author)

The purpose of this study was to compare health-related quality of life (HRQOL) in patients receiving preoperative stoma marking by a certified wound, ostomy and continence nurse (CWOCN) to patients who did not receive preoperative marking. Quasi-experimental, nonrandomized comparison cohort study. The sample comprised 59 patients immediately following creation of a fecal stoma during an 18-month period between 2008 and 2010. The experimental group consisted of 35 patients with a mean age of 49.7 years who received preoperative stoma site marking by a CWOCN. Six of those 35 patients (17%) received preoperative ostomy education and stoma site marking. The control group consisted of 24 patients with a mean age of 60.1 years who did not receive preoperative stoma site marking or preoperative ostomy education. The study setting was a 500-bed Midwest Magnet-designated teaching hospital. Data collection occurred at 2 points: within 72 hours before hospital discharge and 8 weeks after discharge. The Stoma Quality of Life (Stoma-QOL) instrument was used to measure HRQOL. Two CWOCNs and 3 RNs, all members of Memorial's Ostomy & Wound Services, administered the Stoma QOL within 72 hours before hospital discharge. The 2 CWOCNs followed a scripted message to collect functional lifestyle factors and administer the Stoma-QOL, for the second time at 8 weeks after discharge. Groups were compared using analysis of covariance to control for age; analysis demonstrated significantly higher HOQOL in the marked group compared to the unmarked group (F = 4.9, P = .031). Findings demonstrated that patients who underwent stoma site marking reported higher HRQOL than those who did not.

The postoperative growth rates achieved in eight early pubertal adolescent males with Crohn's disease undergoing surgery for obstructive complications is reported as a function of the use of 1 month's preoperative central venous alimentation. All patients had ileal strictures with ileocolitis, bone ages less than 13, Tanner stages 1 or 2, and growth velocities below the 3rd percentile for age. During a 3-year follow-up, those receiving preoperative venous alimentation demonstrated greater oral caloric intake (significant for 1 year) and greater postoperative growth velocity (significant for 2 years) in comparison to those patients who did not receive preoperative venous alimentation. There was no significant difference between the two groups of patients in postoperative weight gain, sexual development, and 3-year disease control.

We evaluated the preoperative CT findings in 10 patients with colon carcinoma in whom peritoneal metastases had been surgically confirmed. Seven patients lacked ascites. No CT findings suggestive of peritoneal metastasis were observed in two patients without ascites even by retrospective evaluation. A large mass was observed in the cul-de-sac in another. In the remaining four patients, small peritoneal metastases ranging from 8 to 11 mm in diameter were observed at the omentum in two, along the falciform ligament in one, and at both the omentum and the iliac fossa in one; three of these patients had received no prospective diagnosis of peritoneal metastasis prior to the surgery. In patients with advanced colon carcinoma with suspected serosal invasion, the entire peritoneal cavity should be carefully examined and interpreted using CT in order to detect small peritoneal implants even when ascites is absent.

The objectification of pain is essential for evaluation, treatment plan and follow-up; therefore, it is necessary to find reliable clinical parameters. The goal of the study was the preoperative screening of a neuropathic component in patients with vertebral compression fracture (WKF), herniated disc (NPP) or spinal cord compression (SKS). Depending on the preoperative condition on admittance, patients were classified into three groups: group 1 WKF, group 2 NPP and group 3 SKS. To characterize the pain we used the painDETECT questionnaire, the Oswestry questionnaire and further questionnaires. All patients were surgically treated according to the diagnosis, e.g. radiofrequency kyphoplasty, nucleotomy or spondylodesis. We evaluated the data from 139 patients (45% WKF, 34% NPP and 21% SKS). There were no differences in preoperative pain intensity (median ordinal scale 0-10) with a mean preoperative score of 7 for all groups. The total score of the painDETECT questionnaire showed significantly higher results in group 2 (median 18) and in group 3 (median 14) than in group 1 (median 9). There was even a significant difference between groups 2 and 3 (p = 0.03). The highest pain intensity was detected in group 1 with a median visual analog scale (VAS) of 71 mm. The total scores in the painDETECT questionnaire and the scores in the Oswestry questionnaire correlated in groups 2 and 3. The painDETECT questionnaire was shown to be a very suitable instrument for evaluating the neuropathic pain component in patients with dorsalgia. This could be very useful in planning further therapy.

Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

Cardiogenic shock after cardiac surgery leads to severely increased mortality. Intra-aortic balloon pumps may be used during the preoperative period to increase coronary perfusion. The purpose of this study was to characterize predictors of postoperative cardiogenic shock in cardiac surgery patients with and without intra-aortic balloon pumps support. We performed a retrospective analysis of our institutional database of the Society of Thoracic Surgeons for patients operated between January 2008 to July 2015. Multivariable logistic regression was used to model postoperative cardiogenic shock in both the intra-aortic balloon pumps and matched control cohorts. Overall, 4,741 cardiac surgery patients were identified during the study period, of whom 192 (4%) received a preoperative intra-aortic balloon pump. Intra-aortic balloon pumps patients had a greater prevalence of diabetes, previous cardiac surgery, congestive heart failure, and an urgent/emergent status (P pumps patients also had greater 30-day mortality and more postoperative cardiogenic shock (9% vs 3%, P pumps cohort, only sex, previous percutaneous coronary intervention and preoperative arrhythmia remained significant on multivariable analysis (all P pumps and those who do not. Further analysis of the effects of prophylactic intra-aortic balloon pumps support is warranted. (Surgery 2017;160:XXX-XXX.). Copyright © 2017 Elsevier Inc. All rights reserved.

Preoperative control of hyperthyroidism in patients with TSH-secreting pituitary adenomas (TSHoma) may avoid perioperative thyroid storm. Perioperative administration of octreotide may control hyperthyroidism, as well as shrink tumor size. The effects of preoperative octreotide treatment were assessed in a large number of patients with TSHomas. Of 81 patients who underwent surgery for TSHoma at Toranomon Hospital between January 2001 and May 2013, 44 received preoperative short-term octreotide. After excluding one patient because of side effects, 19 received octreotide as a subcutaneous injection, and 24 as a long-acting release (LAR) injection. Median duration between initiation of octreotide treatment and surgery was 33.5 days. Octreotide normalized free T4 in 36 of 43 patients (84%) and shrank tumors in 23 of 38 (61%). Length of octreotide treatment did not differ significantly in patients with and without hormonal normalization (p=0.09) and with and without tumor shrinkage (p=0.84). Serum TSH and free T4 concentrations, duration of treatment, incidence of growth hormone (GH) co-secretion, results of octreotide loading tests, form of administration (subcutaneous injection or LAR), tumor volume, and tumor consistency did not differ significantly in patients with and without hormonal normalization and with and without tumor shrinkage. Short-term preoperative octreotide administration was highly effective for TSHoma shrinkage and normalization of excess hormone concentrations, with tolerable side effects.

Preoperative patient education: can we improve satisfaction and reduce anxiety?

2015-02-01

Full Text Available BACKGROUND AND OBJECTIVES: Patients' knowledge deficits concerning anesthesia and the anesthesiologist's role in their care may contribute to anxiety. The objective of this study was to develop anesthesia patient education materials that would help improve patient's satisfaction regarding their knowledge of the perioperative process and decrease anxiety in a community hospital with a large Spanish-speaking population. METHODS: A survey (Survey A in English and Spanish was administered to all adult anesthesiology preoperative clinic patients during a 4-week period. The data were analyzed and then a patient education handout was developed in both English and Spanish to assist with our patients' major concerns. A second survey (Survey B was administered that was completed after the education handout had been put into use at the clinic. The survey asked for basic demographic information and included questions on satisfaction with regard to understanding of anesthesia as well as worries regarding surgery and pain. RESULTS: In the patients who received the handout, statistically significant improvement was found in the questions that asked about satisfaction with regard to understanding of type of anesthesia, options for pain control, what patients are supposed to do on the day of surgery, and the amount of information given with regard to anesthetic plan. There was no difference in anxiety related to surgery in patients who received the educational handout compared to those patients who did not. CONCLUSIONS: Patient education handouts improved patient's satisfaction regarding their knowledge of the perioperative process but did not reduce anxiety related to surgery.

One hundred and nine patients with advanced head and neck cancers (oral cavity: 50, oropharynx: 11, hypopharynx: 18, larynx: 30) received preoperative radiotherapy from 1987 through 1997 in our institute. The median age was 66 years (20-83). Almost all patients had advanced disease (stage II: 17, III: 34, IV: 58). The median dose of preoperative radiotherapy was 40 Gy (20-50). Seventy patients received chemotherapy. The median follow-up time was 30 months. The 5-year overall and disease-free survival rates of all patients were 66% and 56%, respectively. The 5-year locoregional and distant failure rates were 36% and 10%, respectively. The locoregional failure rate of oral cavity cancer (54%) was worse than those of other sites (13-28%) (p=0.0015). The locoregional failure rates of oral cavity cancers according to clinical stage were 59% (II), 57% (III) and 48% (IV), respectively. Incidentally those of other sites were 0% (II), 16% (III) and 30% (IV), respectively. Thirty-eight patients had major complication after surgery. The locoregional failure rates of preoperative radiotherapy following surgery for oral cavity cancers of all stages and other sites of stage IV were high. Preoperative radiotherapy should be stopped and postoperative radiotherapy for these patients should be considered. (author)

Purpose: To investigate the association of high-dose preoperative chemoradiotherapy (CRT) and dose-volume histogram (DVH) parameters of lungs with incidence of postoperative pulmonary complications and to identify predictive clinical factors of pulmonary complications. Methods: Data of 65 patients were collected retrospectively. Thirty-five patients underwent transthoracic esophagectomy (TTE) alone and 30 received cisplatin and 5-fluorouracil, concomitant with radiotherapy, median dose 66 Gy, and followed by TTE. From the DVH for each lung alone and for both lungs together as one organ we generated total lung volume, mean radiotherapy dose, relative and absolute volumes receiving more than a threshold dose, and relative and absolute volumes receiving less than a threshold dose. Postoperative pulmonary complications were defined as pneumonia or respiratory failure. Results: Sixty percent of the patients in the TTE alone group had postoperative pulmonary complications versus 63% in the CRT + TTE group. Postoperative mortality was 8.6% and 16.7% in the respective patient groups (p = NS). None of the DVH parameters was associated with postoperative pulmonary complications. Squamous cell carcinoma was an adverse factor related to increased postoperative pulmonary complications. Conclusion: High-dose preoperative CRT was not associated with increased postoperative pulmonary complications in this cohort of esophageal cancer patients.

Hematotoxicity following anti-cancer treatment is known to be related to treatment efficacy in several malignancies. The purpose of this study was to examine the hematologic parameters related to the tumor response and survival in patients treated with curative surgery following preoperative chemoradiotherapy (CRT) for rectal cancer. Four hundred eighteen patients with rectal cancer who underwent preoperative CRT and curative surgery were analyzed, retrospectively. The main clinical factors and blood cell counts before and after CRT were investigated with respect to their relationships with tumor downstaging and patient survival. The post-CRT leukocyte count was significantly different between the tumor downstaging group and the nondownstaging group (median, 4740/uL vs. 5130/uL; p = 0.013). Multivariate analysis showed that histological grade, circumferential extent, and post-CRT leukocyte count were related to tumor downstaging. In addition, histological grade, post-CRT leukocyte count, and tumor downstaging were related to disease-free survival. The 5-year disease-free survival and overall survival in patients with post-CRT leukocyte count ≤3730/uL, which is the cut-off value derived from the receiver operation characteristic (ROC) curve analysis, were significantly higher than those with higher counts (88.0% vs. 71.6%, p = 0.001; 94.4% vs. 84.1%, p = 0.024). Post-CRT leukocyte count of ≤3730/uL could be regarded as a good prognostic factor for tumor response and survival in rectal cancer patients treated with preoperative CRT.

We counted expedient to include different methods of the soft-laser use in the preoperative medicinal program and in the postoperative period. During the preoperative preparation the basic group patients together with standard treatment received the combined soft-laser therapy, which included intravenous laser blood irradiation (ILBI) by He-Ve laser and external transcutaneous irradiation of the abscess projection by semi-conductorial arrenite-gallium laser. During postoperative treatment with ILBI remarkable changes were observed in the functional activity of the T- and B- cell. The soft-laser use allowed to achieve improvement of quality and shortening of terms of the preoperative preparation of 1,4 times, to level the immunosuppressive influence of surgery to reduce amount of the postoperative complications in 1,8 times and duration of the postoperative period in 1,5 times.

Purpose: Accelerated partial breast irradiation (APBI) after breast-conserving therapy is currently under investigation in prospective randomized studies. Multifocality and multicentricity are exclusion criteria for APBI. Preoperative breast magnetic resonance imaging (MRI) can detect ipsilateral and contralateral invasive tumor foci or ductal carcinoma in situ in addition to conventional diagnostic methods (clinical examination, mammography, and ultrasonography). The objective of this retrospective study was to evaluate the impact of preoperative MRI on patient selection for APBI. Methods and Materials: From 2002 to 2007, a total of 579 consecutive, nonselected patients with newly diagnosed early-stage breast cancer received preoperative breast MRI in addition to conventional imaging studies at the Bonn University Breast Cancer Center. In retrospect, 113 patients would have met the criteria for APBI using conventional imaging workup (clinical tumor size ≤3 cm; negative axillary lymph node status; unifocal disease; no evidence of distant metastases; no invasive lobular carcinoma, ductal and lobular carcinoma in situ, or Paget’s disease). We analyzed the amount of additional ipsilateral and contralateral tumor foci detected by MRI. Results: MRI detected additional tumor foci in 8.8% of patients eligible for APBI (11 tumor foci in 10 of 113 patients), either ipsilateral (n = 7, 6.2%) or contralateral (n = 4, 3.5%). In 1 patient, MRI helped detect additional tumor focus both ipsilaterally and contralaterally. Conclusions: Preoperative breast MRI is able to identify additional tumor foci in a clinically relevant number of cases in this highly selected group of patients with low-risk disease and may be useful in selecting patients for APBI.

Full Text Available Abstract Background There are concerns that pre-operative psychological distress might be associated with reduced patient satisfaction after total hip replacement (THR. Methods We investigated this in a multi-centre prospective study between January 1999 and January 2002. We dichotomised the patients into the mentally distressed (MHS ≤ 56 and the not mentally distressed (MHS > 56 groups based on their pre-operative Mental Health Score (MHS of SF36. Results 448 patients (340 not distressed and 108 distressed completed the patient satisfaction survey. Patient satisfaction rate at five year was 96.66% (415/448. There was no difference in patient satisfaction or willingness to have the surgery between the two groups. None of pre-operative variables predicted five year patient satisfaction in logistic regression. Conclusions Patient satisfaction after surgery may not be adversely affected by pre-operative psychological distress.

Aims To explore the issues and challenges of care transitions in the preoperative environment. Background Ineffective transitions play a role in a majority of serious medical errors. There is a paucity of research related to the preoperative arena and the multiple inherent transitions in care that occur there. Design Qualitative descriptive design was used. Methods Semi-structured interviews were conducted in a 975 bed academic medical center. Results 30 providers and 10 preoperative patients participated. Themes that arose were: (1) Need for clarity of purpose of preoperative care (2) Care coordination (3) Inter-professional boundaries of care (4) Inadequate time and resources. Conclusion Effective transitions in the preoperative environment require that providers bridge scope of practice barriers to promote good teamwork. Preoperative care that is a product of well-informed providers and patients can improve the entire perioperative care process and potentially influence post-operative patient outcomes. Relevance to Clinical Practice Nurses are well positioned to bridge the gaps within transitions of care and accordingly affect health outcomes. PMID:27706872

During the period from 2002 to 2011, a total of 240 consecutive patients with resectable pancreatic cancer received preoperative chemoradiation therapy (CRT). Among 240 patients, 201 patients underwent the subsequent pancreatectomy (resection rate: 84%). The 5-year overall survival of resected cases was 56% and the median survival of 39 unresected cases was 11 months. The 5-year locoregional recurrence rate of resected cases was 15%. The 5-year overall survival of the entire cohort (n=240) was 47%. The preoperative CRT and subsequent pancreatectomy provided a favorable surgical result, which was contributed by several characteristics of preoperative CRT: the prominent locoregional treatment effect with lower incidence of locoregional recurrence, and the discrimination between patients who are likely to benefit from subsequent surgery and those who are not.

Full Text Available Objective: Preoperative anxiety is a prevalent concern with negative effects on perioperative period but is usually ignored. The objectives of this study are to identify the preoperative anxiety levels of surgical patients and to evaluate the associated factors affecting this level. Methods: One hundred volunteer patients scheduled for elective surgery were included the study. Data were collected by using “Personal Information Form “and “State-Trait Anxiety Inventory-I”. Evaluations were based on a significance level of p<0.05. Results: The percentage of female to male patients was 48% and 52%. The mean anxiety levels of both gender were 42.46 ± 8.95 and 42.10 ± 9.49 respectively (p=0.85. There was no difference between females and males in terms of anxiety. Age, occupational condition, marital status, and education level was not found as determinant factors on preoperative anxiety levels. Male individuals of large families were more anxious than the others, but this difference was not significant (p=0.11. Previous surgical experience was not a predictive factor for preoperative anxiety. The anxiety level was significantly high in men using cigarette and alcohol (p<0.01. Fear, apprehension, and stress was highly related with high level of anxiety, but insecurity and inexperience were not a predicting factor. The anxiety levels of cool patients were significantly lower than the others (p<0.01. Conclusions: Preoperative anxiety is a multifactorial issue and must be good handled. The aim must be based on reduction strategies. It must be considered that preoperative information is the best way to decrease preoperative anxiety.

Full Text Available Background: Primary hyperaparathyroidism (pHPT is often accompanied by underlying thyroid pathology that can confound preoperative parathyroid localization studies and complicate intra-operative decision making. The aim of this study was to examine the utility of preoperative thyroid ultrasonography (US in patients prior to undergoing parathyroidectomy for pHPT.Methods: An Institutional Review Board approved prospective study was undertaken from January 2005 through July 2008. All patients with pHPT meeting inclusion criteria (n=94 underwent preoperative thyroid ultrasound in addition to standard 99mTc-sestamibi scintigraphy for parathyroid localization. Demographics, operative management and final pathology were examined in all cases.Results: Fifty-four of the 94 patients (57% were noted to have a thyroid nodule on preoperative US, of which 30 (56% underwent further examination with fine needle aspiration biopsy. Alteration of the operative plan attributable to underlying thyroid pathology occurred in 16 patients (17%, with patients undergoing either total thyroidectomy (n=9 or thyroid lobectomy (n=7. Thyroid cancer was noted in 33% of patients undergoing thyroid resection, and 6% of all patients with HPT.Conclusions: The routine utilization of preoperative thyroid ultrasound in patients prior to undergoing parathyroid surgery for pHPT is indicated. The added information from this non-invasive modality facilitates timely management of co-incidental, and sometimes malignant, thyroid pathology.

Head and neck cancer patients treated with surgery often experience significant postoperative morbidities. Administering preoperative nutritional intervention may improve surgical outcomes, but there is currently a paucity of data reviewing the association between preoperative nutritional status and postoperative outcome. It is therefore of importance to investigate this association among head and neck cancer patients. To assess the association between preoperative nutritional status and postoperative outcome in head and neck cancer patients treated with surgery, a retrospective study of 70 head and neck cancer patients who were surgically treated between 2013 and 2014 in a tertiary referral head and neck surgery center in Hong Kong was conducted. Clinical data regarding preoperative nutritional status and postoperative outcome were retrieved from a computer record system. Logistic and linear regressions were used to analyze the appropriate parameters. A higher preoperative albumin level was associated with lower rates of postoperative complications and better wound healing (P cancer patients, preoperative intervention strategies that boost albumin levels could be considered for improving surgical outcome.

Methods: A retrospective case review of 1,992 eyes (1,364 patients treated between March 2007 and January 2009 was conducted, with a follow up of over 4 years. After identifying cases of ectasia, all the patient charts were examined retrospectively for preoperative findings suggestive of forme fruste keratoconus (FFKC. Results: Five eyes of four patients with post-LASIK ectasia were identified. All eyes passed preoperative screening and received bilateral LASIK. One of the five patients developed ectasia in both eyes. Three patients retrospectively revealed preoperative topography suggestive of FFKC, while one patient had no identifiable preoperative risk factors. Upon review of all the charts, a total 69 eyes, including four of the five eyes with ectasia, were retrospectively found to have topographies suggestive of FFKC. Conclusion: We identified four cases of post-LASIK ectasia that had risk factors for FFKC on reexamination of the chart and one case of post-LASIK ectasia with no identifiable preoperative risk factors. The most conservative screening recommendations would not have precluded this patient from LASIK. The rate of purely iatrogenic post-LASIK ectasia at our center was 0.05% (1/1,992, and the total rate of post-LASIK ectasia for our entire study was 0.25% (1/398. The rate of eyes with unrecognized preoperative FFKC that developed post-LASIK ectasia was 5.8% (1/17. Keywords

There are few data concerning the impact of preoperative renal function, assessed using estimated glomerular filtration rate, on surgical outcomes following acute type A aortic dissection. We investigated the accuracy of estimated glomerular filtration rate (in ml/min/1.73 m(2)) in predicting in-hospital mortality and postoperative renal replacement therapy in such cases. We reviewed 114 consecutive patients with non-dialysis-dependent renal dysfunction who underwent thoracic aortic surgery for acute type A aortic dissection between 1997 and 2012. Preoperative renal function was categorized as normal (estimated glomerular filtration rate >90; n = 15) or as mild (60-89; n = 39), moderate I (45-59; n = 39), moderate II (30-44; n = 14) or severe (15-29; n = 7) renal dysfunction. In-hospital mortality was 14.9%. Eighteen (15.8%) of 114 patients required renal replacement therapy. A more severe stage stratified by preoperative estimated glomerular filtration rate levels could effectively predict postoperative renal replacement therapy (area under the receiver operating characteristic curve 0.786). The best cut-off value of estimated glomerular filtration rate for predicting postoperative renal replacement therapy was 60 (sensitivity 95%, specificity 59%). On multiple regression analysis, the independent preoperative and intraoperative risk factors for postoperative renal replacement therapy were estimated glomerular filtration rate (P replacement (P replacement therapy (OR, 5.47; P regression analysis. Preoperative estimated glomerular filtration rate can effectively predict the need for renal replacement therapy after surgery for acute type A aortic dissection. However, it is not an effective diagnostic tool to predict in-hospital mortality. The complexity of the characteristics of patients who undergo surgical procedures may make prediction of surgical outcomes difficult. Risk models to predict hospital mortality and morbidities are needed to assist clinicians in

To investigate if electrocardiogram (ECG) markers from routine preoperative ECGs can be used in combination with clinical data to predict new-onset postoperative atrial fibrillation (POAF) following cardiac surgery. Retrospective observational case-control study. Single-center university hospital. One hundred consecutive adult patients (50 POAF, 50 without POAF) who underwent coronary artery bypass grafting, valve surgery, or combinations. Retrospective review of medical records and registration of POAF. Clinical data and demographics were retrieved from the Western Denmark Heart Registry and patient records. Paper tracings of preoperative ECGs were collected from patient records, and ECG measurements were read by two independent readers blinded to outcome. A subset of four clinical variables (age, gender, body mass index, and type of surgery) were selected to form a multivariate clinical prediction model for POAF and five ECG variables (QRS duration, PR interval, P-wave duration, left atrial enlargement, and left ventricular hypertrophy) were used in a multivariate ECG model. Adding ECG variables to the clinical prediction model significantly improved the area under the receiver operating characteristic curve from 0.54 to 0.67 (with cross-validation). The best predictive model for POAF was a combined clinical and ECG model with the following four variables: age, PR-interval, QRS duration, and left atrial enlargement. ECG markers obtained from a routine preoperative ECG may be helpful in predicting new-onset POAF in patients undergoing cardiac surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

Between 2 and 8 weeks before surgery, most bariatric surgery groups establish strict dietary treatments with a total caloric intake of less than 1,000 kcal/day in order to maximize weight loss during this period of time. A prospective randomized clinical trial of all the patients undergoing laparoscopic sleeve gastrectomy (LSG) was performed. Patients were randomly assigned into 3 groups: those patients receiving a preoperative regular diet of 900 kcal/day (group 1), those receiving a preoperative balanced energy high-protein formula (group 2) and those receiving preoperative Immunonutrition (group 3). Preoperative weight loss, postoperative pain, complications and analytical acute phase reactants were investigated. Sixty patients were included in the study, 20 in each group. Preoperative excess weight loss was 7.7 % in group 1, 12.3 % in group 2 and 15.3 % in group 3 (p = 0.014). Median postoperative pain was 3.5 in group 1, 3 in group 2 and 2 in group 3 (p = 0.048). C-reactive protein determined 24 h after surgery was significantly lower in group 3 than in the other groups. AST and ALT values were significantly lower in group 3 than in the other groups, without significant differences between groups 1 and 2. Preoperative diet with Immunonutrition formulas during 2 weeks achieves a greater preoperative weight loss, lower postoperative pain and lower values of CRP and liver enzymes than high-protein formulas or regular diet, all of them with similar caloric intake.

Full Text Available Background Disfiguring complications of adolescent idiopathic scoliosis (AIS could significantly affect the patients’ satisfaction. In this regard, shoulder imbalance has recently received much attention in spite of its poorly understood challenge. Objectives While the majority of previous studies have attempted to explore preoperative determinants of postoperative shoulder imbalance, in this study we aimed to investigate the factors correlated with the preoperative shoulder imbalance. Methods A total of 72 AIS patients with no previous history of corrective surgery took part in this study. The study sample comprised 63 females and 9 males with the mean age of 15.72 ± 3.08 years, ranging from 11 to 26 years. Shoulder imbalance parameters including T1 tilt, first rib angle (FRA, and clavicle angle (CA were assessed and their correlation with radiographic characteristics of the curves and patients’ demographic data including age and sex was evaluated. Results T1 tilt was more severe in males (mean -8.2° than females (mean -2.8° (P = 0.04. Moreover, a significant correlation was found between age and FRA (P = 0.04. A significant correlation was also observed between main thoracic (MT curve size and all the three parameters of shoulder imbalance (P < 0.001. The reverse correlation of T5 - T12 kyphosis angle with FRA was also significant (P = 0.04. Conclusions According to our results, in AIS, pre-operative radiographic shoulder imbalance could be affected by some curve parameters including MT and kyphosis size and demographic characteristics of patients including age and gender.

A clinical nursing path (CNP) that encourages patients and their families to become actively involved in healthcare decision-making processes may improve outcomes of pediatric retroperitoneal neuroblastoma (NB) patients. The aim of this study was to evaluate the utility and value of an evidence-based CNP provided to pediatric retroperitoneal NB patients undergoing resection surgery. One hundred twenty NB cases were assigned to a control group or a CNP group. The control group was provided with standard nursing care. The CNP group was provided with nursing care in accordance with an evidence-based CNP. The utility and value of the CNP were compared with standard nursing care. Outcome measures included rates of postoperative complications, lengths of hospital stay, and cost of hospitalization, as well as preoperative and postoperative quality of care and patient satisfaction with care. The rates of postoperative complications, length of preoperative hospitalization, total length of hospital stay, and costs of hospitalization were significantly lower for patients receiving the CNP compared with the control group. Preoperative and postoperative quality of care and patient satisfaction with care were significantly higher in patients receiving the CNP compared with the control group. Adoption of a CNP for preoperative and postoperative care of pediatric retroperitoneal NB patients undergoing resection surgery improves clinical outcomes and patient satisfaction with care. A CNP can increase families' participation in a patient's recovery process, enhance nurses' understanding of the services they are providing, and improve the quality of healthcare received by patients.

Proximal junctional failure (PJF) is a recognized complication of spinal deformity surgery. Acute PJF (APJF) has recently been demonstrated to be 5.6% in the adult spinal deformity (ASD) population. The incidence and rate of return to the operating room for APJF have not been specifically investigated in individuals with sagittal imbalance. The purpose of this study was to report the incidence of APJF in patients with preoperative sagittal imbalance and the rate of return to the operating room for APJF. This study is based on a retrospective review of prospectively collected database of ASD patients. One hundred seventy-three consecutive patients were included with preoperative sagittal imbalance according to one of the following common parameters: sagittal vertical axis (SVA) greater than 50 mm, global sagittal alignment greater than 45°, or pelvic incidence minus lumbar lordosis greater than 10°. Outcome measure was presence and/or absence of APJF defined as fracture at the upper instrumented vertebra (UIV) or UIV+1, failure of UIV fixation, 15° or more proximal junctional kyphosis, or need for extension of instrumentation within 6 months of surgery. We performed radiographic measurements on X-rays at preoperative, immediate postoperative, and 6-month follow-up visits. The APJF rate was reported for the entire patient population with preoperative sagittal imbalance. Acute PJF incidence was calculated postoperatively for each of the accepted sagittal balance parameters and/or formulas. Patients with persistent postoperative sagittal imbalance were compared with the sagittally balanced group. We also assessed for threshold values. Acute PJF was observed in 60 of 173 patients (35%) and was least common in fusions with the UIV in the upper thoracic (UT) spine (p=.035). Of those who developed APJF, 21.7% required surgery. Proximal junctional kyphosis 15° or more was the most common form of APJF in fusions to the UT spine but least likely to need revision (p=.014

To investigate the effects of oral carbohydrate solution consumed until 2 h before the surgery in the patients that would undergo open radical retropubic prostatectomy on postoperative metabolic stress, patient anxiety, and comfort. A total of 50 adult patients, who were in ASA I-II group and would undergo open radical retropubic prostatectomy, were included in the study. While Group 1 = CH (n = 25) received oral glucose solution, Group 2 = FAM (n = 25) was famished starting from 24:00 h. Blood glucose, insulin, and procalcitonin levels of the patients were recorded, and the patients completed state-trait anxiety inventory (STAI) test, which reflects the anxiety level of the patients, both before surgery and on the postoperative 24th hour. In order to evaluate patient comfort, senses of hunger, thirst, nausea, and cold were assessed in the morning prior to the surgery. No difference was observed between the two groups in terms of demographic data and insulin resistance levels (p > 0.05). Comparing with the preoperative levels, insulin resistance showed statistically significant elevation in both groups (p 0.05). With regard to preoperative patient comfort, sense of hunger was present in lesser number of subjects and at lower level in Group 1 (p hunger and thirst in the preoperative period in open radical retropubic prostatectomies.

Sugammadex has steroid-encapsulating effect. This study was undertaken to assess whether the clinical efficacy of sugammadex was altered by the administration of steroids. Sixty patients between 18 and 60 years of age with the American Society of Anesthesiologists I-IV and undergoing elective direct laryngoscopy/biopsy were included in this study. Patients were assigned to two groups based on the intraoperative steroid use: those who received steroid (Group S) and who did not (Group C). After standard general anesthesia, patients were monitored with the train of four (TOF) monitoring. The preferred steroid and its dose, timing of steroid administration, and TOF value before and after sugammadex as well as the time to recovery (TOF of 0.9) were recorded. SPSS software version 17.0 was used for statistical analysis. There is no statistically significant difference between groups in terms of age, gender, preoperative medication use, and TOF ratio just before administering sugammadex. The reached time to TOF 0.9 after sugammadex administration was significantly shorter in Group S than Group C (P sugammadex as well as the dose of sugammadex in those who received prednisolone; time to TOF 0.9 was higher in prednisolone receivers as compared to dexamethasone receivers (P sugammadex was found, in contrast with what one expect. Further studies are required to determine the cause of this effect which is probably due to a potential interaction between sugammadex and steroids.

Abstract Chronic pain after joint replacement is common, affecting approximately 10% of patients after total hip replacement (THR) and 20% of patients after total knee replacement (TKR). Heightened generalized sensitivity to nociceptive input could be a risk factor for the development of this pain. The primary aim of this study was to investigate whether preoperative widespread pain sensitivity was associated with chronic pain after joint replacement. Data were analyzed from 254 patients receiving THR and 239 patients receiving TKR. Pain was assessed preoperatively and at 12 months after surgery using the Western Ontario and McMaster Universities Osteoarthritis Pain Scale. Preoperative widespread pain sensitivity was assessed through measurement of pressure pain thresholds (PPTs) at the forearm using an algometer. Statistical analysis was conducted using linear regression and linear mixed models, and adjustments were made for confounding variables. In both the THR and TKR cohort, lower PPTs (heightened widespread pain sensitivity) were significantly associated with higher preoperative pain severity. Lower PPTs were also significantly associated with higher pain severity at 12 months after surgery in the THR cohort. However, PPTs were not associated with the change in pain severity from preoperative to 12 months postoperative in either the TKR or THR cohort. These findings suggest that although preoperative widespread pressure pain sensitivity is associated with pain severity before and after joint replacement, it is not a predictor of the amount of pain relief that patients gain from joint replacement surgery, independent of preoperative pain severity.

Dipyridamole-thallium imaging has been suggested as a method of preoperatively assessing cardiac risk in patients undergoing major surgery. To define more clearly its proper role in preoperative assessment, we prospectively evaluated 111 patients undergoing vascular surgery. In the first set of 61 patients, our data confirmed the value of preoperative dipyridamole-thallium scanning in identifying the patients who suffered postoperative ischemic events. Events occurred in eight of 18 patients with reversible defects on preoperative imaging, compared with no events in 43 patients with no thallium redistribution (confidence interval for the risk difference: 0.624, 0.256). The results also suggested that clinical factors might allow identification of a low-risk subset of patients. To test the hypothesis that patients with no evidence of congestive heart failure, angina, prior myocardial infarction, or diabetes do not require further preoperative testing, we evaluated an additional 50 patients having vascular procedures. None of the 23 without the clinical markers had untoward outcomes, while ten of 27 patients with one or more of these clinical markers suffered postoperative ischemic events (confidence interval for the risk difference: 0.592, 0.148). In the clinical high-risk subset, further risk stratification is achieved with dipyridamole-thallium scanning

Weight loss and malnutrition are disorders observed in colorectal cancer patients. We sought to evaluate the immediate preoperative nutritional status of patients with colorectal cancer. This is a cross-sectional clinical study conducted at a single center. Sixty-six consecutive patients in preoperative for elective surgical treatment were studied. The clinical history, socio-demographic data and nutritional status of the patients were evaluated using Subjective Global Assessment and objective (anthropometry) methods. The primary outcome measures were nutritional status classification as nourished or malnourished and the relationship between nutritional status and socio-demographic and clinical features. Most of patients exhibited left colon tumors and disease stage II. According to the Subjective Global Assessment, 36.4% of patients were malnourished. Malnutrition ranged from 7.6% to 53% depending on the evaluation method used, with poor correlation to Subjective Global Assessment. The prevalence of malnutrition was significantly greater in females and non-married patients and in those with two or more symptoms of colorectal cancer. More than a third of patients in the immediate preoperative period for colorectal cancer exhibited malnutrition. Therefore, routine nutritional assessment is highly advisable so that appropriate measures may be taken to minimize the potential postoperative complications.

Objectives The relationship between preoperative medical consultations and postoperative complications has not been extensively studied. Thus, we investigated the impact of preoperative consultation on postoperative morbidity following elective abdominal aortic aneurysm repair. Methods A retrospective review was conducted on 469 patients (mean age 72 years, 20% female) who underwent elective abdominal aortic aneurysm repair from June 2007 to July 2014. Data elements included detailed medical history, preoperative cardiology consultation, and postoperative complications. Primary outcomes included 30-day morbidity, consult-specific morbidity, and mortality. A bivariate probit regression model accounting for the endogeneity of binary preoperative medical consult and patient variability was estimated with a maximum likelihood function. Results Eighty patients had preoperative medical consults (85% cardiology); thus, our analysis focuses on the effect of cardiac-related preoperative consults. Hyperlipidemia, increased aneurysm size, and increased revised cardiac risk index increased likelihood of referral to cardiology preoperatively. Surgery type (endovascular versus open repair) was not significant in development of postoperative complications when controlling for revised cardiac risk index ( p = 0.295). After controlling for patient comorbidities, there was no difference in postoperative cardiac-related complications between patients who did and did not undergo cardiology consultation preoperatively ( p = 0.386). Conclusions When controlling for patient disease severity using revised cardiac risk index risk stratification, preoperative cardiology consultation is not associated with postoperative cardiac morbidity.

It has rarely been reported about the changes of hemoglobin (Hb) and hematocrit (Hct) in elderly patients receiving total knee arthroplasty (TKA) or total hip arthroplasty (THA). This study aimed to evaluate the changes of Hb and Hct after TKA or THA in elderly patients, and analyze its relationship with sex and type of arthroplasty. This is a prospective cohort study, including 107 patients receiving TKA or THA without allogeneic blood transfusion. There were 54 males and 53 females, with a mean age of 69.42 years. Levels of Hb and Hct were examined preoperatively and during the 6 months follow-up after operation. Levels of Hb and Hct decreased postoperatively and reached their minimum points on postoperative day 4. Thereafter, Hb and Hct recovered to their preoperative levels within 6-12 weeks. No significant differences in the levels of Hb and Hct were noticed between different sexes. THA patients showed significantly greater drop in Hb and Hct than TKA patients in the first 4 days postoperatively (P < 0.05). Levels of Hb and Hct decreased during the first 4 days after arthroplasty and gradually returned to their normal levels within 6-12 weeks postoperatively. THA may be associated with higher postoperative blood loss than TKA.

Pre-operative anxiety is common and often significant. Ambulatory surgery challenges our pre-operative goal of an anxiety-free patient by requiring people to be 'street ready' within a brief period of time after surgery. Recently, it has been demonstrated that music can be used successfully to relieve patient anxiety before operations, and that audio embedded with tones that create binaural beats within the brain of the listener decreases subjective levels of anxiety in patients with chronic anxiety states. We measured anxiety with the State-Trait Anxiety Inventory questionnaire and compared binaural beat audio (Binaural Group) with an identical soundtrack but without these added tones (Audio Group) and with a third group who received no specific intervention (No Intervention Group). Mean [95% confidence intervals] decreases in anxiety scores were 26.3%[19-33%] in the Binaural Group (p = 0.001 vs. Audio Group, p Binaural beat audio has the potential to decrease acute pre-operative anxiety significantly.

Pre-operative skin preparation, aimed at reducing the endogenous microbial flora, is one of the main preventive measures employed to decrease the likelihood of surgical site infection. National recommendations on pre-operative management of infection risks were issued in France in 2004. To assess compliance with the French national guidelines for pre-operative skin preparation in 2007. A prospective audit was undertaken in French hospitals through interviews with patients and staff, and observation of professional practice. Compliance with five major criteria selected from the guidelines was studied: patient information, pre-operative showering, pre-operative hair removal, surgical site disinfection and documentation of these procedures. Data for 41,188 patients from all specialties at 609 facilities were analysed. Patients were issued with information about pre-operative showering in 88.2% of cases [95% confidence interval (CI) 87.9-88.5]. The recommended procedure for pre-operative showering, including hairwashing, with an antiseptic skin wash solution was followed by 70.3% of patients (95% CI 69.9-70.8); this percentage was higher when patients had received appropriate information (P pre-operative surgical hygiene, 82.3% of cases; and pre-operative site disinfection, 71.7% of cases. The essential content of the French guidelines seems to be understood, but reminders need to be issued. Some recommendations may need to be adapted for certain specialties.

Objective: To evaluate the clinical value of the preoperative intra-arterial embolization of the nasopharyngeal angiofibromas. Methods: The treatment group of 7 male patients with the nasopharyngeal angiofibromas were undergone angiographic evaluation and embolization of tumor-feeding vessels before surgery. All patients were embolized with gelfoam particles and PVA. The control group of 7 patients received surgical treatment without preoperative embolization. The authors compared the volumes of intraoperative bleeding and the blood transfusions during operations between the two groups. Results: All patients achieved symptomatic remission, with no complications. Comparing with the control group, the amount of intraoperative bleeding and the blood transfusions during operations were much less in the treatment group submitted to endovascular embolization. Marked edema in the peripheral region of tumor of the treatment group made the tumor easy to be dissociated. Conclusion: The intraoperative bleeding can be reduced significantly by preoperative embolization of supplying arteries to the nasopharyngeal angiofibromas, therefore it should be used routinely as an adjunct to surgery.

Poor nutrition status is considered a risk factor for postoperative complications in the adult population. In elderly patients, who often have a poor nutrition status, this relationship has not been substantiated. Thus, the aim of this systematic review was to assess the merit of preoperative nutrition parameters used to predict postoperative outcome in elderly patients undergoing general surgery. A systematic literature search of 10 consecutive years, 1998-2008, in PubMed, EMBASE, and Cochrane databases was performed. Search terms used were nutrition status, preoperative assessment, postoperative outcome, and surgery (hip or general), including their synonyms and MeSH terms. Limits used in the search were human studies, published in English, and age (65 years or older). Articles were screened using inclusion and exclusion criteria. All selected articles were checked on methodology and graded. Of 463 articles found, 15 were included. They showed profound heterogeneity in the parameters used for preoperative nutrition status and postoperative outcome. The only significant preoperative predictors of postoperative outcome in elderly general surgery patients were serum albumin and ≥ 10% weight loss in the previous 6 months. This systematic review revealed only 2 preoperative parameters to predict postoperative outcome in elderly general surgery patients: weight loss and serum albumin. Both are open to discussion in their use as a preoperative nutrition parameter. Nonetheless, serum albumin seems a reliable preoperative parameter to identify a patient at risk for nutrition deterioration and related complicated postoperative course.

Bronchial asthma is characterized by chronic airway inflammation. The primary goal of treatment of asthma is to maintain the state of control. According to the Japanese guidelines (JGL2012), long-term management consists of 4 therapeutic steps, and use of inhaled corticosteroids (ICS) is recommended at all 4 steps. Besides ICS, inhalation of long-acting β2-agonist (LABA) is also effective. Recently, omalizumab (a humanized antihuman IgE antibody) can be available for patients with severe allergic asthma. Although there is no specific strategy for preoperative treatment of patients with asthma, preoperative systemic steroid administration seemed to be effective to prevent asthma attack during anesthesia. The most common cause of chronic bronchitis is smoking. Even the respiratory function is within normal limits, perioperative management of patients with chronic bronchitis is often troublesome. The most common problem is their sputum. To minimize perioperative pulmonary complication in these patients, smoking cessation and pulmonary rehabilitation are essential. It is known that more than 1 month of smoking cessation is required to reduce perioperative respiratory complication. However, even one or two weeks of smoking cessation can decrease sputum secretion. In summary, preoperative optimization is most important to prevent respiratory complication in patients with bronchial asthma or chronic bronchitis.

Purpose: The goal of this study was to evaluate dosimetric parameters, acute toxicity, pathologic response, and local control in patients treated with preoperative intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy for localized gastric adenocarcinoma. Methods: Between November 2007 and April 2010, 25 patients with localized gastric adenocarcinoma were treated with induction chemotherapy, followed by preoperative IMRT and concurrent chemotherapy and, finally, surgical resection. The median radiation therapy dose was 45 Gy. Concurrent chemotherapy was 5-fluorouracil and oxaliplatin in 18 patients, capecitabine in 3, and other regimens in 4. Subsequently, resection was performed with total gastrectomy in 13 patients, subtotal gastrectomy in 7, and other surgeries in 5. Results: Target coverage, expressed as the ratio of the minimum dose received by 99% of the planning target volume to the prescribed dose, was a median of 0.97 (range, 0.92-1.01). The median V{sub 30} (percentage of volume receiving at least 30 Gy) for the liver was 26%; the median V{sub 20} (percentage of volume receiving at least 20 Gy) for the right and left kidneys was 14% and 24%, respectively; and the median V{sub 40} (percentage of volume receiving at least 40 Gy) for the heart was 18%. Grade 3 acute toxicity developed in 14 patients (56%), including dehydration in 10, nausea in 8, and anorexia in 5. Grade 4 acute toxicity did not develop in any patient. There were no significant differences in the rates of acute toxicity, hospitalization, or feeding tube use in comparison to those in a group of 50 patients treated with preoperative three-dimensional conformal radiation therapy with concurrent chemotherapy. R0 resection was obtained in 20 patients (80%), and pathologic complete response occurred in 5 (20%). Conclusions: Preoperative IMRT for gastric adenocarcinoma was well tolerated, accomplished excellent target coverage and normal structure sparing, and led to appropriate

From 1984 through 1986, six patients with extrahepatic bile duct tumor were treated preoperatively with intraluminal irradiation of the bile duct. There were no unresectable cases and pathological examination of the surgical specimens showed moderate to remarkable tumor regression in all cases. Postoperative biliary tract hemorrhage occurred in 2 of 3 patients who received 60 Gy at a point 7.5 mm from the center of the source. With accurate preoperative diagnosis of the tumor extent and careful setting of the target area of intraluminal irradiation, improved local tumor control of extrahepatic bile duct tumor can be expected with this method.

Purpose: Preoperative chemoradiation therapy (CRT) has become the standard treatment strategy for patients with resectable esophageal cancer. This multicenter phase 2 study investigated the efficacy of the addition of the epidermal growth factor receptor (EGFR) inhibitor panitumumab to a preoperative CRT regimen with carboplatin, paclitaxel, and radiation therapy in patients with resectable esophageal cancer. Methods and Materials: Patients with resectable cT1N1M0 or cT2-3N0 to -2M0 tumors received preoperative CRT consisting of panitumumab (6 mg/kg) on days 1, 15, and 29, weekly administrations of carboplatin (area under the curve [AUC] = 2), and paclitaxel (50 mg/m{sup 2}) for 5 weeks and concurrent radiation therapy (41.4 Gy in 23 fractions, 5 days per week), followed by surgery. Primary endpoint was pathologic complete response (pCR) rate. We aimed at a pCR rate of more than 40%. Furthermore, we explored the predictive value of biomarkers (EGFR, HER 2, and P53) for pCR. Results: From January 2010 until December 2011, 90 patients were enrolled. Patients were diagnosed predominantly with adenocarcinoma (AC) (80%), T3 disease (89%), and were node positive (81%). Three patients were not resected due to progressive disease. The primary aim was unmet, with a pCR rate of 22%. Patients with AC and squamous cell carcinoma reached a pCR of 14% and 47%, respectively. R0 resection was achieved in 95% of the patients. Main grade 3 toxicities were rash (12%), fatigue (11%), and nonfebrile neutropenia (11%). None of the biomarkers was predictive for response. Conclusions: The addition of panitumumab to CRT with carboplatin and paclitaxel was safe and well tolerated but could not improve pCR rate to the preset criterion of 40%.

Purpose: The secreted protein acidic and rich in cysteine-like 1 (SPARCL1) is expressed in various normal tissues and many types of cancers. The function of SPARCL1 and its relationship to a patient's prognosis have been studied, whereas its relationship to radiation therapy (RT) is not known. Our aim was to investigate the expression of SPARCL1 in rectal cancer patients who participated in a clinical trial of preoperative RT. Methods and Materials: The study included 136 rectal cancer patients who were randomized to undergo preoperative RT and surgery (n=63) or surgery alone (n=73). The expression levels of SPARCL1 in normal mucosa (n=29), primary tumor (n=136), and lymph node metastasis (n=35) were determined by immunohistochemistry. Results: Tumors with RT had stronger SPARCL1 expression than tumors without RT (P=.003). In the RT group, strong SPARCL1 expression was related to better survival than weak expression in patients with stage III tumors, independent of sex, age, differentiation, and margin status (P=.022; RR = 18.128; 95% confidence interval, 1.512-217.413). No such relationship was found in the non-RT group (P=.224). Further analysis of interactions among SPARCL1 expression, RT, and survival showed statistical significance (P=.024). In patients with metastases who received RT, strong SPARCL1 expression was related to better survival compared to weak expression (P=.041) but not in the non-RT group (P=.569). Conclusions: SPARCL1 expression increases with RT and is related to better prognosis in rectal cancer patients with RT but not in patients without RT. This result may help us to select the patients best suited for preoperative RT.

Purpose: To analyze the rate of pathologic response in patients with locally advanced gastric cancer treated with preoperative chemotherapy with and without chemoradiation at our institution. Methods and Materials: From 2000 to 2007 patients were retrospectively identified who received preoperative treatment for gastric cancer (cT3-4/ N+) with induction chemotherapy (Ch) or with Ch followed by concurrent chemoradiotherapy (45 Gy in 5 weeks) (ChRT). Surgery was planned 4-6 weeks after the completion of neoadjuvant treatment. Pathologic assessment was used to investigate the patterns of pathologic response after neoadjuvant treatment. Results: Sixty-one patients were analyzed. Of 61 patients, 58 (95%) underwent surgery. The R0 resection rate was 87%. Pathologic complete response was achieved in 12% of the patients. A major pathologic response (<10% of residual tumor) was observed in 53% of patients, and T downstaging was observed in 75%. Median follow-up was 38.7 months. Median disease-free survival (DFS) was 36.5 months. The only patient-, tumor-, and treatment-related factor associated with pathologic response was the use of preoperative ChRT. Patients achieving major pathologic response had a 3-year actuarial DFS rate of 63%. Conclusions: The patterns of pathologic response after preoperative ChRT suggest encouraging intervals of DFS. Such a strategy may be of interest to be explored in gastric cancer.

Objective: To discuss the perioperative nursing care of patients who is going to receive interventional therapy for hepatic artery stenosis after liver transplantation and to provide useful reference for reducing surgery-related complication and for improving the prognosis of patients. Methods: Based on the patient's condition and operative requirement,we provided effective nursing care for 20 patients who were admitted to receive the interventional therapy for hepatic artery stenosis after liver transplantation. The nursing care included preoperative preparation,postoperative nursing and medical guidance at the time of discharge. Results: Interventional therapy was successfully performed in all 20 cases, and no hemorrhagic tendency or acute thrombosis occurred. Marked symptomatic improvement was obtained in all patients. Conclusion: The interventional therapy is an effective treatment for hepatic artery stenosis after liver transplantation. Intensive perioperative nursing care can well prevent the occurrence of surgery-related complications and can surely improve the therapeutic results. (authors)

We collected data before and after surgery on intraocular pressure (IOP, anterior chamber (AC cells, best-corrected visual acuity (BCVA, morphologic characteristics of the filtering bleb and complications.Results: The mean time between injection and surgery was 7.8±3.88 days. Postoperative IOP level was significantly lower than preoperative level (31.3±11.44 mmHg at all visits (P<0.02. Antiglaucoma medications were decreased from preoperative (4.9±0.88 to 12-month postoperative (0.8±1.31; P-value <0.001 and also discontinued in seven eyes (70%. About 12 months after surgery, eight eyes (80% with qualified success and two eyes (20% with failed treatment were recorded. AC cells and BCVA did not differ significantly from baseline; however, all inflammations were controlled successfully. Most desirable bleb morphology was shown at 12 months as well. Complications were blepharoptosis and hypotony maculopathy in two eyes (20%.Conclusion: A preoperative PSTA may be an effective and safe option in controlling intraocular inflammation and maintaining bleb function after trabeculectomy in noninfectious uveitic patients with secondary glaucoma during a 12-month period.

To assess the clinical effect of cochlear implant programming on tinnitus. Tinnitus patients (n = 234) were divided into 3 groups: (1) preoperative tinnitus (n = 108), (2) postoperative tinnitus occurring before implant switch-on at week 4 (n = 88), and (3) tinnitus occurring more than 1 year postoperatively (n = 44). Patients in each group were randomly allocated into a programming subgroup that received programming for 12 weeks postoperatively or after tinnitus occurrence or a control subgroup. Impedance testing and the Tinnitus Handicap Inventory (THI) were performed preoperatively and at 4, 6, 8, and 12 weeks postoperatively (groups 1 and 2) or after tinnitus occurrence (group 3). Comparisons were performed using t tests and chi-square tests. Impedance was significantly lower in the programming subgroup than in the control subgroup in groups 1 and 2 at 8 and 12 weeks and in group 3 at 12 weeks. The THI scores decreased in both programming and control subgroups in all groups. However, this decrease was pronounced in the programming subgroup, whereas in the control subgroup, it occurred slowly over time. Cochlear implant programming decreases impedance and improves tinnitus symptoms. © The Author(s) 2015.

The prevention of postoperative complications is of prime importance after complex elective abdominal operations. Preoperative patient education may prevent postoperative complications and improve patients' wellbeing, but evidence for its efficacy is poor. The aims of the PEDUCAT trial were (a) to assess the impact of preoperative patient education on postoperative complications and patient-reported outcomes in patients scheduled for elective complex visceral surgery and (b) to evaluate the feasibility of cluster randomization in this setting. Adult patients (age ≥ 18 years) scheduled for elective major visceral surgery were randomly assigned in clusters to attend a preoperative education seminar or to the control group receiving the department's standard care. Outcome measures were the postoperative complications pneumonia, deep vein thrombosis (DVT), pulmonary embolism, burst abdomen, and in-hospital fall, together with patient-reported outcomes (postoperative pain, anxiety and depression, patient satisfaction, quality of life), length of hospital stay (LOS), and postoperative mortality within 30 days after the index operation. Statistical analysis was primarily by intention to treat. In total 244 patients (60 clusters) were finally included (intervention group 138 patients; control group 106 patients). Allocation of hospital wards instead of individual patients facilitated study conduct and reduced confusion about group assignment. In the intervention and control groups respectively, pneumonia occurred in 7.4% versus 8.3% (p = 0.807), pulmonary embolism in 1.6% versus 1.0% (p = 0.707), burst abdomen in 4.2% versus 1.0% (p = 0.165), and in-hospital falls in 0.0% versus 4.2% of patients (p = 0.024). DVT did not occur in any of the patients. Mortality rates (1.4% versus 1.9%, p = 0.790) and LOS (14.2 (+/- 12.0) days versus 16.1 (+/- 15.0) days, p = 0.285) were also similar in the intervention and control groups. Cluster

Non-gastrointestinal stromal tumor sarcomas (NGSs) have heterogeneous histology, and this heterogeneity may lead to uncertainty regarding the prognosis of patients with liver metastases from NGS (NGSLM) and decision regarding their surgical management. Furthermore, the role of preoperative chemotherapy in treatment of NGSLM remains poorly defined. We investigated long-term survival and its correlation to response to preoperative chemotherapy in patients with NGSLM. Patients who underwent liver resection for NGSLM during 1998-2015 were identified. Clinical, histopathologic, and survival data were analyzed. Multivariate analysis was performed using a Cox proportional hazards model. 126 patients [62 (49%) with leiomyosarcoma] were included. Five-year overall survival (OS) and recurrence-free survival (RFS) rates were 49.3 and 14.9%, respectively. Survival did not differ by histologic subtype, primary tumor location, or use of preoperative or postoperative chemotherapy. NGSLM ≥ 10 cm and extrahepatic metastases at NGSLM diagnosis were the only independent risk factors for OS. In the 83 (66%) patients with metachronous NSGLM, disease-free interval > 6 months was associated with improved OS and RFS. Among the 65 patients (52%) who received preoperative chemotherapy, radiologic response according to Choi criteria specifically was associated with improved OS (p = 0.04), but radiologic response according to RECIST 1.1 criteria was not. Resection of NGSLM led to a 5-year OS rate of 49%, independent of histologic subtype and primary tumor location. Choi criteria (which take into account tumor density) are superior to RECIST 1.1 in assessing radiologic response and should be used to assess response to preoperative chemotherapy.

Aim: To ascertain the degree of adherence to the guideline recommendation on pre-operative RT/ChT for stage-II and -III patients in Catalonian public hospitals, and its impact on local recurrence among rectal cancer patients. Methods: Data were derived from a multicentre retrospective cohort study of patients who underwent curative-intent surgery for primary rectal cancer at Catalonian public hospitals in 2005 and 2007. Results: The study covered 1229 patients with TNM stage-II or -III primary rectal cancer. Of these patients, 54.5% underwent pre-operative RT/ChT; 14.9% underwent post-operative RT (± chemotherapy); and 30.6% did not undergo any RT. The crude local recurrence rate at 2 years was 4.1% and the crude distant recurrence rate at 2 years was 6.5%. The results of the univariate analyses showed a local-recurrence hazard ratio of 1.84 for the group of patients that received no RT versus the group that received pre-operative RT/ChT (p < 0.01). Conclusions: This is the first population-based study in Catalonia to support the use of pre-operative RT/ChT in rectal cancer patients because, in line with the results of population-based studies reported from other countries, its application, compared to non-application of RT, was found to lead to a clear reduction in the probability of local recurrence.

To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

The role of magnetic resonance imaging to select patients for preoperative treatment in rectal cancer

Roedel, Claus; Sauer, Rolf; Fietkau, Rainer

2009-01-01

Background: Traditionally, the decision to apply preoperative treatment for rectal cancer patients has been based on the T- and N-category. Recently, the radial distance of the tumor to the circumferential resection margin (CRM) has been identified as an important risk factor for local failure. By magnetic resonance imaging (MRI) this distance can be measured preoperatively with high reliability. Thus, selected groups have started to limit the indication for preoperative therapy to tumors extending to - or growing within 1 mm from - the mesorectal fascia (CRM+). Methods: Pros and cons of this selected approach for preoperative treatment and first clinical results are presented. Prerequisites are the availability of modern high-resolution thin-section MRI technology as well as strict quality control of MRI and surgical quality of total mesorectal excision (TME). Results: By selecting patients with CRM-positive tumors on MRI for preoperative therapy, only approximately 35% patients will require preoperative radiotherapy (RT) or radiochemotherapy (RCT). However, with histopathologic work-up of the resected specimen after primary surgery, the indication for postoperative RCT is given for a rather large percentage of patients, i.e., for pCRM+ (5-10%), intramesorectal or intramural excision (30-40%), pN+ (30-40%). Postoperative RCT, however, is significantly less effective and more toxic than preoperative RCT. A further point of concern is the assertion that patients, in whom a CRM-negative status is achieved by surgery alone, do not benefit from additional RT. Data of the Dutch TME trial and the British MRC (Medical Research Council) CR07 trial, however, suggest the reverse. Conclusion: To omit preoperative RT/RCT for CRM-negative tumors on MRI needs to be further investigated in prospective clinical trials. The German guidelines for the treatment of colorectal cancer 2008 continue to indicate preoperative RT/RCT based on the T- and N-category. (orig.)

To quantify ensuing bone marrow (BM) suppression during postoperative chemotherapy resulting from preoperative chemoradiation (CRT) therapy for rectal cancer. We retrospectively evaluated 35 patients treated with preoperative CRT followed by postoperative 5-Fluorouracil and oxaliplatin (OxF) chemotherapy for locally advanced rectal cancer. The pelvic bone marrow (PBM) was divided into ilium (IBM), lower pelvis (LPBM), and lumbosacrum (LSBM). Dose volume histograms (DVH) measured the mean doses and percentage of BM volume receiving between 5-40 Gy (i.e.: PBM-V5, LPBM-V5). The Wilcoxon signed rank tests evaluated the differences in absolute hematologic nadirs during neoadjuvant vs. adjuvant treatment. Logistic regressions evaluated the association between dosimetric parameters and ≥ grade 3 hematologic toxicity (HT3) and hematologic event (HE) defined as ≥ grade 2 HT and a dose reduction in OxF. Receiver Operator Characteristic (ROC) curves were constructed to determine optimal threshold values leading to HT3. During OxF chemotherapy, 40.0% (n=14) and 48% (n=17) of rectal cancer patients experienced HT3 and HE, respectively. On multivariable logistic regression, increasing pelvic mean dose (PMD) and lower pelvis mean dose (LPMD) along with increasing PBM-V (25-40), LPBM-V25, and LPBM-V40 were significantly associated with HT3 and/or HE during postoperative chemotherapy. Exceeding ≥36.6 Gy to the PMD and ≥32.6 Gy to the LPMD strongly correlated with causing HT3 during postoperative chemotherapy. Neoadjuvant RT for rectal cancer has lasting effects on the pelvic BM, which are demonstrable during adjuvant OxF. Sparing of the BM during preoperative CRT can aid in reducing significant hematologic adverse events and aid in tolerance of postoperative chemotherapy. Copyright © 2016 Elsevier Inc.

Renal failure (RF) represents a major postoperative complication for elderly patients undergoing cardiac surgery. This observational cohort study examines effects of preoperative use of renin-angiotensin system (RAS) inhibitors on postoperative renal failure in aging patients undergoing cardiac surgery. We retrospectively analyzed a cohort of 1287 patients who underwent cardiac surgery at this institution (2003-2007). The patients included were ≥65 years old, scheduled for elective cardiac surgery, and without preexisting RF (defined by the criteria of the Society of Thoracic Surgeons as described in Method). Of all patients evaluated, 346 patients met the inclusion criteria and were divided into two groups: using (n = 122) or not using (n = 224) preoperative RAS inhibitors. A comparison of the two groups showed no significant differences in baseline parameters, including creatinine clearance, body mass index, history of diabetes and smoking, preoperative medicines (except that more patients with RAS inhibitors had a history of hypertension or congestive heart failure, fewer RAS inhibitor patients had chronic lung disease), in intraoperative perfusion and aortic cross-clamp time, and in postoperative complications and 30-d mortality. Multivariate logistic regression analysis demonstrated, however, that preoperative RAS inhibitors significantly and independently reduced the incidence of postoperative RF in the patients undergoing cardiac surgery compared with those not taking RAS inhibitors: 1.6% versus 7.6%, yielding an odds ratio of 0.19 (95 % CI 0.04-0.84, P = 0.029). Preoperative RAS inhibitors may have significant renoprotective effects for aging patients undergoing elective cardiac surgery. Copyright © 2011 Elsevier Inc. All rights reserved.

Aim of this study is the evaluation of the impact of a multimedia CD (MCD) on preoperative anxiety and postoperative recovery of patients undergoing elective laparoscopic cholecystectomy (LC). Sixty consecutive candidates for elective LC were randomly assigned to four groups. Group A included 15 patients preoperatively informed regarding LC through the MCD presented by Registered Nurse (RN). Patients in group B (n = 15) were informed through a leaflet. Patients in group C (n = 15) were informed verbally from a RN. Finally, the control Group D included 15 patients informed conventionally by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, and C. Preoperative assessment of knowledge about LC was performed after each informative session through a questionnaire. Evaluation of preoperative anxiety was conducted using APAIS scale. Postoperative pain and nausea scores were measured using an NRS scale, 16 hours after the patient had returned to the ward. Statistical processing of the results (single linear regression) showed that patients in groups A, B, and C achieved a higher knowledge score, less preoperative anxiety score and less postoperative pain and nausea, compared to Group D. In multiple regression analysis, group A had a higher knowledge score compared to the four groups (p Informative sessions using MCD is an effective means of improving patient's preoperative knowledge, especially in day-surgery cases, like LC.

To evaluate the impact of preoperative biliary drainage on surgical morbidity in hilar cholangiocarcinoma patients underwent surgery. One hundred and eleven consecutive patients with hilar cholangiocarcinoma whose serum total bilirubin (TBIL) level > 85 micromol/L and underwent surgery in the period from June 1998 to August 2007 were enrolled. There were 67 male and 44 female patients, aged from 26 to 82 years old with a mean of 56 years old. Fifty-five patients underwent preoperative biliary drainage with a mean of 11.4 d of drainage period (drainage group), the other (n = 56) were the non-drainage group. The preoperative TBIL level of drainage group was (154 +/- 69) micromol/L, which was significantly lower than the value of pre-drainage (256 +/- 136) micromol/L (P = 0.000) and the value of non-drainage group (268 +/- 174) micromol/L (P = 0.005). ALT and GGT levels could be lowered by preoperative biliary drainage. The postoperative complications of these two groups were comparable (36.3% vs. 28.6%, P = 0.381). Four patients in drainage group and 5 patients in non-drainage group died of liver failure. Multivariate logistic regression indicated that hepatectomy (OR = 0.284, P = 0.003) was the independent risk factor associated with postoperative morbidity. Bismuth-Corlette classification (OR = 0.211, P = 0.028) was the independent risk factor linked to postoperative mortality. Preoperative biliary drainage could alleviate liver injury due to hyperbilirubin, but it could not decrease the surgical morbidity and postoperative mortality. Concomitant hepatectomy and Bismuth-Corlette classification were independent risk factors linked to surgical risks.

Purpose: The German rectal study determined that preoperative radiation therapy (RT) as a component of combined-modality therapy decreased local tumor recurrence, increased sphincter preservation, and decreased treatment toxicity compared with postoperative RT for rectal cancer. We evaluated the use of preoperative RT after the presentation of the landmark German rectal study results and examined the impact of tumor and sociodemographic factors on receiving preoperative RT. Methods and Materials: In total, 20,982 patients who underwent surgical resection for T3-T4 and/or node-positive rectal adenocarcinoma diagnosed from 2000 through 2006 were identified from the Surveillance, Epidemiology, and End Results tumor registries. We analyzed trends in preoperative RT use before and after publication of the findings from the German rectal study. We also performed multivariate logistic regression to identify factors associated with receiving preoperative RT. Results: Among those treated with RT, the proportion of patients treated with preoperative RT increased from 33.3% in 2000 to 63.8% in 2006. After adjustment for age; gender; race/ethnicity; marital status; Surveillance, Epidemiology, and End Results registry; county-level education; T stage; N stage; tumor size; and tumor grade, there was a significant association between later year of diagnosis and an increase in preoperative RT use (adjusted odds ratio, 1.26/y increase; 95% confidence interval, 1.23-1.29). When we compared the years before and after publication of the German rectal study (2000-2003 vs. 2004-2006), patients were more likely to receive preoperative RT than postoperative RT in 2004-2006 (adjusted odds ratio, 2.35; 95% confidence interval, 2.13-2.59). On multivariate analysis, patients who were older, who were female, and who resided in counties with lower educational levels had significantly decreased odds of receiving preoperative RT. Conclusions: After the publication of the landmark German rectal

OBJECTIVE Patient satisfaction is a commonly used metric in the current health care environment. While factors that affect patient satisfaction following spine surgery are complex, the authors of this study hypothesized that specific diagnostic groups of patients are more likely to be satisfied after spine surgery and that this is reflected in patient-reported outcome measures. The purpose of this study was to determine if the preoperative diagnosis-disc herniation, stenosis, spondylolisthesis, adjacent segment degeneration, or mechanical disc collapse-would impact patient satisfaction following surgery. METHODS Patients enrolled in the Quality Outcomes Database, formerly known as the National Neurosurgery Quality and Outcomes Database (N 2 QOD), completed patient-reported outcome measures, including the Oswestry Disability Index (ODI) and Numeric Rating Scale (NRS) for back pain (NRS-BP) and leg pain (NRS-LP) preoperatively and 1-year postoperatively. Patients were stratified by diagnosis and by their response to the satisfaction question: 1) surgery met my expectations; 2) I did not improve as much as I hoped, but I would undergo the same operation for the same results; 3) surgery helped, but I would not undergo the same operation for the same results; or 4) I am the same or worse as compared with before surgery. RESULTS A greater proportion of patients with primary disc herniation or spondylolisthesis reported that surgery met expectations (66% and 67%, respectively), followed by recurrent disc herniation and stenosis (59% and 60%, respectively). A smaller proportion of patients who underwent surgery for adjacent segment degeneration or mechanical disc collapse had their expectations met (48% and 41%, respectively). The percentage of patients that would undergo the same surgery again, by diagnostic group, was as follows: disc herniation 88%, recurrent disc herniation 79%, spondylolisthesis 86%, stenosis 82%, adjacent segment disease 75%, and mechanical collapse

To determine whether mixed-flora preoperative urine cultures, as compared with no-growth preoperative urine cultures, are associated with a higher prevalence of postoperative urinary tract infections (UTIs). This was a retrospective cohort study. Women who underwent urogynecologic surgery were included if their preoperative clean-catch urine culture result was mixed flora or no growth. Women were excluded if they received postoperative antibiotics for reasons other than treatment of a UTI. Women were divided into two cohorts based on preoperative urine culture results-mixed flora or no growth; the prevalence of postoperative UTI was compared between cohorts. Baseline characteristics were compared using χ 2 or Student t tests. A logistic regression analysis then was performed. We included 282 women who were predominantly postmenopausal, white, and overweight. There were many concomitant procedures; 46% underwent a midurethral sling procedure and 68% underwent pelvic organ prolapse surgery. Preoperative urine cultures resulted as mixed flora in 192 (68%) and no growth in 90 (32%) patients. Overall, 14% were treated for a UTI postoperatively. There was no difference in the proportion of patients treated for a postoperative UTI between the two cohorts (25 mixed flora vs 13 no growth, P = 0.77). These results remained when controlling for potentially confounding variables in a logistic regression model (adjusted odds ratio 0.92, 95% confidence interval 0.43-1.96). In women with mixed-flora compared with no-growth preoperative urine cultures, there were no differences in the prevalence of postoperative UTI. The clinical practice of interpreting mixed-flora cultures as negative is appropriate.

Leptomeningeal enhancement (LME) on preoperative brain magnetic resonance imaging (MRI) does not always indicate leptomeningeal seeding (LMS). With Stupp's regimen, authors have treated glioblastoma patients with LME on preoperative brain MRI but here we tried to find the clinical impact of LME. From 2005 to 2015, 290 patients with glioblastoma have been treated with Stupp's regimen at Samsung Medical Center. Among these, 33 patients showed LME on preoperative brain MRI. We compared the clinical outcomes between the patients with or without LME on preoperative brain MRI and analyzed the clinical results according to changes of LME at following MRI. The median survival was 23 months, and 2-year overall survival (OS) and disease-free survival (DFS) rate was 46.3% and 19.6%, respectively. Prognostic factors for OS and DFS were Karnofsky performance status, extent of resection and adjuvant chemotherapy. MGMT promoter methylation status was a significant prognostic factor for DFS. However, LME was not a significant prognostic factor for OS (P = 0.156) or DFS (P = 0.193). Among the 33 patients with LME on preoperative MRI, 21 (63.6%) showed persistent LME at the next MRI. A statistically significant difference in 2-year survival was evident between patients with and without persistent LME (OS, 17.3% and 70.1%, respectively, P = 0.044; DFS, 5.3% and 54.0%, respectively, P = 0.006). The most common pattern of failure was local recurrence. However, patients with persistent LME displayed a higher incidence of LMS than patients without LME. LME on preoperative brain MRI did not affect the clinical results in glioblastoma patients treated with the Stupp's regimen. However, persistence of LME was associated with poor survival and high possibility of LMS. For these patients, the postoperative adjuvant treatment should focus on palliative aim or more aggressive treatment scheme should be followed to overcome the disastrous results. © 2018 John Wiley & Sons Australia, Ltd.

This paper presents the most common disorders of pituitary function: acromegaly, hypopituitarism, diabetes insipidus and syndrome similar to diabetes insipidus, in terms of their importance in preoperative preparation of patients. Pituitary function manages almost the entire endocrine system using the negative feedback mechanism that is impaired by these diseases. The cause of acromegaly is a pituitary adenoma, which produces growth hormone in adults. Primary therapy of acromegaly is surgical, with or without associated radiotherapy. If a patient with acromegaly as comorbidity prepares for non-elective neurosurgical operation, then it requires consultation with brain surgeons for possible delays of that operation and primary surgical treatment of pituitary gland. If operative treatment of pituitary gland is carried out, the preoperative preparation (for other surgical interventions) should consider the need for perioperative glucocorticoid supplementation. Panhypopituitarism consequences are different in children and adults and the first step in diagnosis is to assess the function of target organs. Change of electrolytes and water occurs in the case of pituitary lesions in the form of central or nephrogenic diabetes insipidus as a syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Preoperative preparation of patients with pituitary dysfunction should be multidisciplinary, whether it is a neurosurgical or some other surgical intervention. The aim is to evaluate the result of insufficient production of pituitary hormones (hypopituitarism), excessive production of adenohypophysis hormones (acromegaly, Cushing's disease and hyperprolactinemia) and the influence of pituitary tumours in surrounding structures (compression syndrome) and to determine the level of perioperative risk. Pharmacological suppressive therapy of the hyperfunctional pituitary disorders can have significant interactions with drugs used in the perioperative period.

Purpose: FXYD-3 (MAT-8) is overexpressed in several types of cancers; however, its clinical relevance in rectal cancers has not been studied. Therefore, we examined FXYD-3 expression in rectal cancers from the patients who participated in a Swedish clinical trial of preoperative radiotherapy (RT) to determine whether FXYD-3 was overexpressed in rectal cancers and correlated with RT, survival, and other clinicopathologic variables. Methods and Materials: The study included 140 rectal cancer patients who participated in a clinical trial of preoperative RT, 65 with and 75 without RT before surgery. FXYD-3 expression was immunohistochemically examined in distant (n = 70) and adjacent (n = 101) normal mucosa, primary tumors (n = 140), and lymph node metastasis (n = 36). Results: In the whole cohort, strong FXYD-3 expression was correlated with infiltrative tumor growth (p = 0.02). In the RT group, strong FXYD-3 expression alone (p = 0 .02) or combined with phosphatase of regenerating liver was associated with an unfavorable prognosis (p = 0.02), independent of both TNM stage and tumor differentiation. In tumors with strong FXYD-3 expression, there was less tumor necrosis (p = 0.02) and a trend toward increased incidence of distant metastasis (p = 0.08) after RT. None of these effects was seen in the non-RT group. FXYD-3 expression in the primary tumors tended to be increased compared with normal mucosa regardless of RT. Conclusion: FXYD-3 expression was a prognostic factor independent of tumor stage and differentiation in patients receiving preoperative RT for rectal cancer.

Adults and children are required to fast before anaesthesia to reduce the risk of regurgitation and aspiration of gastric contents. However, prolonged periods of fasting are unnecessary and may cause complications. This study was conducted to evaluate preoperative fasting period in our centre and compare it with the ASA recommendations and factors that influence fasting periods. This is a cross-sectional study of preoperative fasting times among elective surgical patients. A total numbers of 260 patients were interviewed as they arrived at the reception area of operating theatre using questionnaire. Majority of patients (98.1%) were instructed to fast from midnight. Fifteen patients (5.8%) reported that they were told the importance of preoperative fasting. The mean fasting period were 15.9±2.5 h (range 12.0-25.3 h) for solids and 15.3±2.3 h (range 12.0-22.0 h) for liquids. The mean duration of fasting was significantly longer for patients operated after midday compared to those operated before midday, pfasting periods were 7.65 times longer for clear liquid and 2.5 times for solids than the ASA guidelines. It is imperative that the Hospital should establish Preoperative fasting policies and teach the staff who should ensure compliance with guidelines.

Cross-sectional study. To objectively evaluate the ability of International Classification of Diseases, Ninth Revision (ICD-9) codes, which are used as the foundation for administratively coded national databases, to identify preoperative anemia in patients undergoing spinal fusion. National database research in spine surgery continues to rise. However, the validity of studies based on administratively coded data, such as the Nationwide Inpatient Sample, are dependent on the accuracy of ICD-9 coding. Such coding has previously been found to have poor sensitivity to conditions such as obesity and infection. A cross-sectional study was performed at an academic medical center. Hospital-reported anemia ICD-9 codes (those used for administratively coded databases) were directly compared with the chart-documented preoperative hematocrits (true laboratory values). A patient was deemed to have preoperative anemia if the preoperative hematocrit was less than the lower end of the normal range (36.0% for females and 41.0% for males). The study included 260 patients. Of these, 37 patients (14.2%) were anemic; however, only 10 patients (3.8%) received an "anemia" ICD-9 code. Of the 10 patients coded as anemic, 7 were anemic by definition, whereas 3 were not, and thus were miscoded. This equates to an ICD-9 code sensitivity of 0.19, with a specificity of 0.99, and positive and negative predictive values of 0.70 and 0.88, respectively. This study uses preoperative anemia to demonstrate the potential inaccuracies of ICD-9 coding. These results have implications for publications using databases that are compiled from ICD-9 coding data. Furthermore, the findings of the current investigation raise concerns regarding the accuracy of additional comorbidities. Although administrative databases are powerful resources that provide large sample sizes, it is crucial that we further consider the quality of the data source relative to its intended purpose.

To investigate the effect of exposure to a virtual reality (VR) environment preoperatively on patient-reported outcomes for surgical operations. There is a scarcity of well-developed quality improvement initiatives targeting patient satisfaction. We performed a randomized controlled trial of patients undergoing cranial and spinal operations in a tertiary referral center. Patients underwent a 1:1 randomization to an immersive preoperative VR experience or standard preoperative experience stratified on type of operation. The primary outcome measures were the Evaluation du Vecu de l'Anesthesie Generale (EVAN-G) score and the Amsterdam Preoperative Anxiety and Information (APAIS) score, as markers of the patient's experience during the surgical encounter. During the study period, a total of 127 patients (mean age 55.3 years, 41.9% females) underwent randomization. The average EVAN-G score was 84.3 (standard deviation, SD, 6.4) after VR, and 64.3 (SD, 11.7) after standard preoperative experience (difference, 20.0; 95% confidence interval, CI, 16.6-23.3). Exposure to an immersive VR experience also led to higher APAIS score (difference, 29.9; 95% CI, 24.5-35.2). In addition, VR led to lower preoperative VAS stress score (difference, -41.7; 95% CI, -33.1 to -50.2), and higher preoperative VAS preparedness (difference, 32.4; 95% CI, 24.9-39.8), and VAS satisfaction (difference, 33.2; 95% CI, 25.4-41.0) scores. No association was identified with VAS stress score (difference, -1.6; 95% CI, -13.4 to 10.2). In a randomized controlled trial, we demonstrated that patients exposed to preoperative VR had increased satisfaction during the surgical encounter. Harnessing the power of this technology, hospitals can create an immersive environment that minimizes stress, and enhances the perioperative experience.

We assess the role of magnetic resonance (MR) as an imaging method for the preoperative localization of pathological parathyroid glands in a series of 14 patients with primary hyperparathyroidism secondary to parathyroid adenoma who underwent surgical resection. We selected 14 patients diagnosed as having primary hyperparathyroidism who underwent preoperative MR. All the studies were carried out with a toshiba MRT 50 MR unit with a 0.5 T superconductor magnet. MR located the adenoma in nine of the 14 patients (64%), including the only two who had previously undergone surgery. Our results indicate that MR without contrast is not effective in the preoperative localization of parathyroid adenomas and should be performed only in patients with recurrent hyperparathyroidism or that persisting after surgical treatment.

One hundred forty-one liver scans, 137 brain scans, and 112 bone scans were performed in 192 patients with clinical Stage 1 melanoma. One liver scan was interpreted as abnormal; liver biopsy of that patient showed no metastasis. There were 11 suggestive liver scans; three of the patients with suggestive liver scans had negative liver biopsies. The remaining eight patients were followed from 4 to 6 years and none of those patients developed clinical evidence of hepatic metastases. All of the brain scans were normal. Five patients had suggestive bone scans and none of those patients had manifested symptoms of osseous metastases with a follow-up of 2 to 4.5 years. This study demonstrates that the use of preoperative liver, brain and bone scan in the evaluation of patients with clinical Stage 1 melanoma is virtually unproductive

Previous studies have suggested that plasma fibrinogen contributes to tumor cell proliferation, progression and metastasis. The current study was performed to evaluate the prognostic relevance of preoperative plasma fibrinogen in breast cancer patients. Data of 2073 consecutive breast cancer patients, who underwent surgery between January 2002 and December 2008 at the Sun Yat-sen University Cancer Center, were retrospectively evaluated. Plasma fibrinogen levels were routinely measured before surgeries. Participants were grouped by the cutoff value estimated by the receiver operating characteristic (ROC) curve analysis. Overall survival (OS) was assessed using Kaplan-Meier analysis, and multivariate Cox proportional hazards regression model was performed to evaluate the independent prognostic value of plasma fibrinogen level. The optimal cutoff value of preoperative plasma fibrinogen was determined to be 2.83 g/L. The Kaplan-Meier analysis showed that patients with high fibrinogen levels had shorter OS than patients with low fibrinogen levels (p factor for OS in breast cancer patients (HR = 1.475, 95% confidence interval (CI): 1.177-1.848, p = 0.001). Subgroup analyses revealed that plasma fibrinogen level was an unfavorable prognostic parameter in stage II-III, Luminal subtypes and triple-negative breast cancer patients. Elevated preoperative plasma fibrinogen was independently associated with poor prognosis in breast cancer patients and may serve as a valuable parameter for risk assessment in breast cancer patients.

Purpose: Capecitabine (Xeloda) is a new orally administered fluoropyrimidine carbamate that was rationally designed to exert its effect by tumor-selective activation. We attempted to evaluate the efficacy and toxicity of preoperative chemoradiation using capecitabine in locally advanced rectal cancer. Methods and Materials: Between July 1999 and March 2001, 45 patients with locally advanced rectal cancer (cT3/T4 or N+) were treated with preoperative chemoradiation. Radiation of 45 Gy/25 fractions was delivered to the pelvis, followed by a 5.4 Gy/3 fractions boost to the primary tumor. Chemotherapy was administered concurrent with radiotherapy and consisted of 2 cycles of 14-day oral capecitabine (1650 mg/m 2 /day) and leucovorin (20 mg/m 2 /day), each of which was followed by a 7-day rest period. Surgery was performed 6 weeks after the completion of chemoradiation. Results: Thirty-eight patients received definitive surgery. Primary tumor and node downstaging occurred in 63% and 90% of patients, respectively. The overall downstaging rate, including both primary tumor and nodes, was 84%. A pathologic complete response was achieved in 31% of patients. Twenty-one patients had tumors located initially 5 cm or less from the anal verge; among the 18 treated with surgery, 72% received sphincter-preserving surgery. No Grade 3 or 4 hematologic toxicities developed. Other Grade 3 toxicities were as follows: hand-foot syndrome (7%), fatigue (4%), diarrhea (4%), and radiation dermatitis (2%). Conclusion: These preliminary results suggest that preoperative chemoradiation with capecitabine is a safe, well-tolerated, and effective neoadjuvant treatment modality for locally advanced rectal cancer. In addition, this preoperative treatment has a considerable downstaging effect on the tumor and can increase the possibility of sphincter preservation in distal rectal cancer

The aim of this study was to develop an effective surgical site infection (SSI) prediction model in patients receiving free-flap reconstruction after surgery for head and neck cancer using artificial neural network (ANN), and to compare its predictive power with that of conventional logistic regression (LR). There were 1,836 patients with 1,854 free-flap reconstructions and 438 postoperative SSIs in the dataset for analysis. They were randomly assigned tin ratio of 7:3 into a training set and a test set. Based on comprehensive characteristics of patients and diseases in the absence or presence of operative data, prediction of SSI was performed at two time points (pre-operatively and post-operatively) with a feed-forward ANN and the LR models. In addition to the calculated accuracy, sensitivity, and specificity, the predictive performance of ANN and LR were assessed based on area under the curve (AUC) measures of receiver operator characteristic curves and Brier score. ANN had a significantly higher AUC (0.892) of post-operative prediction and AUC (0.808) of pre-operative prediction than LR (both P <0.0001). In addition, there was significant higher AUC of post-operative prediction than pre-operative prediction by ANN (p<0.0001). With the highest AUC and the lowest Brier score (0.090), the post-operative prediction by ANN had the highest overall predictive performance. The post-operative prediction by ANN had the highest overall performance in predicting SSI after free-flap reconstruction in patients receiving surgery for head and neck cancer.

This paper reports on low-dose and high-dose radiation therapy (RT) followed by cystectomy for bladder carcinoma that was evaluated for survival, failure patterns, and complications as these outcomes have been incompletely documented in the past. One hundred five patients with clinical stages T2-T4 (muscle-invading) transitional cell carcinoma of the bladder who completed preoperative RT followed by total cystectomy were evaluated. Eighty-five patients received 20-27 Gy in 4-7 fractions (group A). Twenty patients received 40-50 Gy in 20-28 fractions (group B). Actuarial 5-year survival was 45% and 29% (P = .06) for groups A and B, respectively; 6% of group A was stage T4 compared with 30% of group B. Five-year actuarial survival for patients with stages T2-T3 in groups A and B was 46% and 42%, respectively, while that for T4 was 33% and 0% in groups A and B, respectively. Multivariate analysis revealed that stage, grade, and presence of hydronephrosis independently affected survival. Five-year actuarial local control rates for T2, T3, and T4 were 93%, 93%, and 22%, respectively, with no significant difference between RT groups. Rates of distant metastasis and complications versus preoperative regime and stage were similar

Full Text Available To investigate the relationship between preoperative expectations and actual postoperative outcomes of visual function (VF among patients undergoing first eye cataract surgery.A longitudinal study of 182 patients from hospitals in urban Southern China were surveyed prior to surgery and 3 month after cataract surgery regarding their preoperative, expected postoperative and actual postoperative VF for each of the items on the Catquest-9SF and their satisfaction with cataract surgery. In addition, detailed clinical data were collected preoperatively and postoperatively.The majority of cataract patients in urban Southern China had high expectations for VF outcomes after cataract surgery and in most cases postoperative outcomes achieved the expected level of improvement. The mean (standard deviation, SD preoperative Catquest-9SF score was 15.7 (5.86 and the mean (SD expected postoperative score was 26.3 (2.93. The discrepancy between actual and expected improvement was significantly correlated with patients' health literacy, presence of systemic and ocular comorbidity, preoperative visual acuity of the surgery eye, LOCS III nuclear opalescence and cortical cataract grading.Cataract patients in urban Southern China had high expectations for surgery outcomes. Patients with low level of health literacy and the presence of systemic and ocular comorbidity may need a comprehensive counseling to decrease the discrepancy regarding expected and actual outcomes.

  To compare anthropometric z-scores with incidence of post-operative complications for patients undergoing primary cleft lip or palate repair.   This was a retrospective observational analysis of patients from a surgical center in Assam, India, and includes a cohort from a single surgical mission completed before the opening of the center.   Patients included in the study underwent surgery during an Operation Smile mission before the opening of Operation Smile's Guwahati Comprehensive Cleft Care Center in Guwahati, India. The remaining cohort received treatment at the center. All patients received preoperative assessment and screening; surgery; and postoperative care, education, and follow-up.   Our sample size included 1941 patients and consisted of all patients with complete information in the database who returned for follow-up after receiving primary cleft lip repair or primary cleft palate repair between January 2011 and April 2013.   Preoperative anthropometric measurements.   Postoperative complications.   Anthropometric z-scores were not a significant predictor of adverse surgical outcomes in the group analyzed. Palate surgery had increased risk of complication versus lip repair, with an overall odds ratio of 5.66 (P < .001) for all patients aged 3 to 228 months.   Anthropometric z-scores were not correlated with increased risk of surgical complications, possibly because patients were well screened for malnutrition before surgery at this center. Primary palate repair is associated with an approximate fivefold increased risk of developing postoperative complication(s) compared with primary lip repair.

This study was to evaluate the prognostic significance of serum lipids in esophageal squamous cell carcinoma patients who underwent esophagectomy. Preoperative serum lipids were collected from 214 patients who were diagnosed with esophageal squamous cell carcinoma. All of the patients received esophagectomy in Qilu Hospital of Shandong University from January 2007 to December 2008. The records and data were analyzed retrospectively. We found that low total cholesterol (for T stage, p = 0.006; for TNM stage, p = 0.039) and low-density lipoprotein cholesterol (for T stage, p = 0.031; for TNM stage, p = 0.035) were associated with advanced T stage and TNM stage. Kaplan-Meier survival analysis indicated that low total cholesterol and low-density lipoprotein cholesterol were associated with shorter disease-free survival(for total cholesterol, p = 0.045; for low-density lipoprotein cholesterol, p squamous cell carcinoma patients who underwent esophagectomy. LHR can serve as a promising serum lipids-based prognostic indicator.

The aim of the study was to investigate serum thymidine kinase 1 (S-TK) activity as a diagnostic and prognostic marker for patients with pancreatic ductal adenocarcinoma (PDAC). Using the sensitive TK activity assay DiviTum, preoperative serum samples from 404 PDAC, 28 chronic pancreatitis, and 25 autoimmune pancreatitis patients and 83 healthy volunteers were analyzed. The preoperative S-TK activities of 54 PDAC patients who received neoadjuvant therapy (nTx) were also compared with those of 258 PDAC patients who did not receive nTx. The preoperative S-TK activities of PDAC patients were significantly higher and discriminatory from autoimmune and chronic pancreatitis patients and control groups. The S-TK activity in PDAC patients was associated with overall survival. Patients with S-TK activity of less than 80 Du (DiviTum units)/L demonstrated median survival of 20.3 months with an estimated 18.0% 5-year survival rate; for S-TK activity of 80 Du/L or greater, median survival was 15.1 months with a 6.8% 5-year survival rate. For early-stage PDAC, these differences were even more pronounced. The S-TK activity in the nTx group was significantly higher than that in the group not receiving nTx. Pancreatic ductal adenocarcinomas reveal a significant increase in S-TK activity, which is associated with overall survival, especially in early tumor stages. Serum thymidine kinase 1 activity may be a useful parameter for monitoring nTx efficacy.

Aim: To analyse and compare the risks and benefits of preoperative breast MRI (BMRI) in patients with primary breast cancer (PBC), and to determine the influence of mammographic breast density (BD) and histological tumour type (TT). Materials and Methods: One hundred and nineteen patients who underwent preoperative bilateral breast MRI for staging of PBC during a 1-year period from July 2005 to August 2006 were prospectively evaluated. Changes in clinical management due to BMRI findings were recorded. MRI-detected lesions were correlated with histology. Additional MRI-detected malignant lesions and spared additional biopsies because of negative MRI in case of unclear ultrasound findings were determined as beneficial for the patient. Biopsies of benign MRI detected lesions were defined as disadvantageous. The influence of BD (ACR 1-4) and TT on the change in clinical management and patient benefit was evaluated. Results: The findings of the BMRI examinations changed the clinical management in 48 patients (40.3%). Seventeen women underwent mastectomy instead of breast conservation, eight patients underwent extended excision, 21 additional lesions were clarified by MRI intervention, and two ultrasound-detected lesions were not biopsied because of negative MRI. Histologically malignant additional or extended biopsies (n = 34) and two cases of spared biopsies resulted in 36 (30.3%) women who benefited from preoperative BMRI. Twelve patients (10.1%) had additional biopsies of MRI-detected benign lesions, and therefore, had an unfavourable outcome due to BMRI. The change in clinical management and patient benefit were independent of BD and TT (p > 0.05). Conclusion: Preoperative BMRI was beneficial for 30.3% of 119 patients with PBC. The percentage of additional biopsies of benign lesions (10.1%) seems acceptable

The aim of this study was to investigate the predictive potential of pre-operative regional cerebral blood flow (rCBF) in the pre-supplementary motor area (pre-SMA) and clinical factors in Parkinson's disease (PD) patients treated with subthalamic nucleus (STN) stimulation. Ten patients underwent rCBF SPECT and motor Unified Parkinson's Disease Rating Scale (UPDRS) pre- and post-operatively during stimulation at 5 and 42 months. Statistical parametric mapping (SPM) was used to extract rCBF values in the pre-SMA because it is related with motor improvement. Post-operative outcomes included motor response to stimulation and percent improvement in UPDRS. Pre-operative predictors were explored by correlation test, linear regression and multivariate analyses. Higher pre-operative rCBF in the pre-SMA and younger age were associated with favourable outcomes at 5 and 42 months. Pre-operative rCBF results were significantly associated with baseline clinical factors. This study shows that PD patients with younger age have higher rCBF values in the pre-SMA and better outcome, thus giving the rationale to the hypothesis that STN stimulation could be considered early in the course of disease.

Full Text Available Introduction: Urethral strictures are common in urologic practice of Sub-Saharan Africa including Nigeria. We determine the rate of stricture recurrence following urethroplasty for anterior urethral strictures and evaluate preoperative variables that predict of stricture recurrence in our practice. Subjects and Methods: Thirty-six men who had urethroplasty for proven anterior urethral stricture disease between February 2012 and January 2015 were retrospectively analyzed. Preoperative factors including age, socioeconomic factors, comorbidities, etiology of strictures, stricture location, stricture length, periurethral spongiofibrosis, and prior stricture treatments were assessed for independent predictors of stricture recurrence. Results: The median age was 49.5 years (range 21-90, median stricture length was 4 cm (range 1-18 cm and the overall recurrence rate was 27.8%. Postinfectious strictures, pan urethral strictures or multiple strictures involving the penile and bulbar urethra were more common. Most patients had penile circular fasciocutaneous flap urethroplasty. Following univariate analysis of potential preoperative predictors of stricture recurrence, stricture length, and prior treatments with dilations or urethrotomies were found to be significantly associated with stricture recurrence. On multivariate analysis, they both remained statistically significant. Patients who had prior treatments had greater odds of having a recurrent stricture (odds ratio 18, 95% confidence interval [CI] 1.4-224.3. Stricture length was dichotomized based on receiver operating characteristic (ROC analysis, and strictures of length ≥5 cm had significantly greater recurrence (area under ROC curve of 0.825, 95% CI 0.690-0.960, P = 0.032. Conclusion: Patients who had prior dilatations or urethrotomies and those with long strictures particularly strictures ≥5 cm have significantly greater odds of developing a recurrence following urethroplasty in Nigerian

A complex regional pain syndrome of an extremity that has previously resolved can recur after repeat surgery at the same anatomic site. Complex regional pain syndrome is described as a disease of the autonomic nervous system. The purpose of this study was to evaluate preoperative and postoperative sympathetic function and the recurrence of complex regional pain syndrome type I (CRPS I) in patients after repeat carpal tunnel surgery. Thirty-four patients who developed CRPS I after initial carpal tunnel releases and required repeat open carpal tunnel surgeries were studied. Laser Doppler imaging (LDI) was used to assess preoperative sympathetic function 5-7 days prior to surgery and to assess postoperative sympathetic function 19-22 days after surgery or 20-22 days after resolution of the CRPS I. Sympathetic nervous system function was prospectively examined by testing reflex-evoked vasoconstrictor responses to sympathetic stimuli recorded with LDI of both hands. Patients were assigned to 1 of 2 groups based on LDI responses to sympathetic provocation. Group I (11 of 34) patients had abnormal preoperative LDI studies in the hands that had prior surgeries, whereas group II (23 of 34) patients had normal LDI studies. Each patient in this study had open repeat carpal tunnel surgery. In group I, 8 of 11 patients had recurrent CRPS I, whereas in group II, 3 of 23 patients had recurrent CRPS I. All of the recurrent CRPS I patients were successfully treated with sympathetic blockade, occupational therapy, and pharmacologic modalities. Repeat LDI after recurrent CRPS I resolution was abnormal in 8 of 8 group I patients and in 1 of 3 group II patients. CRPS I can recur after repeat hand surgery. Our study results may, however, identify those individuals who may readily benefit from perioperative therapies. Prognostic I.

Full Text Available Objective: To determine the role of preoperative serum cancer antigen 125 (CA 125 in malignant ovarian germ cell tumors (MOGCTs. Materials and methods: Using information from medical databases of Asan Medical Center (Seoul, Korea, we investigated 161 patients with histologically diagnosed MOGCTs and whose preoperative serum CA 125 had been checked. We determined the optimal cutoff value of CA 125 as > 249.5 U/mL in MOGCTs using a receiver operating characteristic curve. Results: The median patient age was 24 years (range, 6–52 years. The most common histologic type was immature teratoma. Most patients had stage I disease. Thirty-two patients (19.9% had elevated preoperative serum CA 125 levels over 249.5 U/mL. On univariate analysis, tumor size, advanced stage, the presence of ascites, ovarian surface involvement, and tumor rupture were significantly associated with elevated preoperative CA 125 levels (>249.5 U/mL. In the median follow-up time of 87 months (range, 9–271 months, 14 patients had a recurrence, and 5 died of the disease. Patients with an elevated serum preoperative CA 125 level (>249.5 U/mL had poorer disease-free survival, but this was not statistically significant. However, elevated preoperative CA 125 (>249.5 U/mL was significantly associated with poorer overall survival. Conclusions: Elevated preoperative serum CA 125 may have prognostic value in patients with MOGCTs. Keywords: CA-125 antigen, Ovarian germ cell cancer, Prognosis

Infective endocarditis (IE) is still associated with high morbidity and mortality. The impact of pre-operative stroke on mortality and long-term survival is controversial. In addition, data on the severity of neurological disability due to pre-operative stroke are scarce. We analysed the impact of pre-operative stroke and the severity of its related neurological disability on short- and long-term outcome. We retrospectively reviewed our data from patients operated for left-sided IE between 01/2007 and 04/2013. We performed univariate (Chi-Square and independent samples t test) and multivariate analyses. Among 308 consecutive patients who underwent cardiac surgery for left-sided IE, pre-operative stroke was present in 87 (28.2 %) patients. Patients with pre-operative stroke had a higher pre-operative risk profile than patient without it: higher Charlson comorbidity index (8.1 ± 2.6 vs. 6.6 ± 3.3) and higher incidence of Staphylococcus aureus infection (43 vs. 17 %) and septic shock (37 vs. 19 %). In-hospital mortality was equal but 5-year survival was significantly worse with pre-operative stroke (33.1 % vs. 45 %, p = 0.006). 5-year survival was worst in patients with severe neurological disability compared to mild disability (19.0 vs. 0.58 %, p = 0.002). However, neither pre-operative stroke nor the degree of neurological disability appeared as an independent risk factor for short or long-term mortality by multivariate analysis. Pre-operative stroke and the severity of neurological disability do not independently affect short- and long-term mortality in patients with infective endocarditis. It appears that patients with pre-operative stroke present with a generally higher risk profile. This information may substantially affect decision-making.

Postoperative analgesia is important because it prevents the adverse effects of pain. To study the effect of preoperative or intraoperative application of dexketoprofen on postoperative analgesia and patient comfort in patients undergoing septorhinoplasty. A randomized, double-blind, placebo-controlled study. The study included 100 patients randomly assigned to four groups. Patients from group 50/0 got 50 mg dexketoprofen 30 minutes prior to the operation; patients from group 0/50 got 50 mg dexketoprofen 30 minutes after the operation, and patients from group 25/25 got 25 mg dexketoprofen both 30 minutes prior and 30 minutes after the operation. Dexketoprofen was not applied to any of the patients from group C. Once in the recovery room, patient-controlled analgesia was received to all patients. The patients' visual analog scale (VAS), sedation, nausea and vomiting and dyspepsia complaints were recorded at 1, 2, 3, 4, 5, 6, 7, 8, 12 and 24 hours. In addition, patient satisfaction, intraoperative fentanyl and consumption of tramadol in the postoperative 24 hour period were recorded. The VAS, nausea and vomiting, sedation and patient satisfaction scores were lower in patients from all groups that had received dexketoprofen compared to the controls. There was no difference in intraoperative fentanyl consumption between the groups. The consumption of tramadol was significantly higher in group C compared to all other groups. Dexketoprofen provides good postoperative analgesia and patient satisfaction if applied intravenously to septorhinoplasty patients. However, there is no significant difference between preoperative and intraoperative applications of dexketoprofen.

Background and purpose: In a recent study, we demonstrated that the ability of dermal fibroblasts, obtained from soft tissue sarcoma (STS) patients, to undergo initial division in vitro following radiation exposure correlated with the development of wound healing morbidity in the patients following their treatment with preoperative radiotherapy. Transforming growth factor beta (TGF-β) is thought to play an important role in fibroblast proliferation and radiosensitivity both of which may impact on wound healing. Thus, in this study we examined the interrelationship between TGF-β activity, radiosensitivity and proliferation of cultured fibroblasts and the wound healing response of STS patients after preoperative radiotherapy to provide a validation cohort for our previous study and to investigate mechanisms. Patients and methods: Skin fibroblasts were established from skin biopsies of 46 STS patients. The treatment group consisted of 28 patients who received preoperative radiotherapy. Eighteen patients constituted a control group who were either irradiated postoperatively or did not receive radiation treatment. Fibroblast cultures were subjected to the colony forming and cytokinesis-blocked binucleation assays (low dose rate: ∼0.02 Gy/min) and TGF-β assays (high dose-rate: ∼1.06 Gy/min) following γ-irradiation. Fibroblast radiosensitivity and initial proliferative ability were represented by the surviving fraction at 2.4 Gy (SF 2.4 ) and binucleation index (BNI), respectively. Active and total TGF-β levels in fibroblast cultures were determined using a biological assay. Wound healing complication (WHC), defined as the requirement for further surgery or prolonged deep wound packing, was the clinical endpoint examined. Results: Of the 28 patients treated with preoperative radiotherapy, 8 (29%) had wound healing difficulties. Fibroblasts from patients who developed WHC showed a trend to retain a significantly higher initial proliferative ability after

The goal of this study was to evaluate whether preoperative pressure pain sensitivity testing is predictive of postoperative surgical pain. Female subjects undergoing lower abdominal gynecologic surgery were studied. A pressure algometer was used preoperatively to determine the pressure pain threshold and tolerance. A visual analog scale (VAS) was used to assess postoperative pain. A State-Trait Anxiety Inventory was used to assess patients' anxiety. Subjects received intravenous patient-controlled analgesia for postoperative pain control. The preoperative pain threshold and tolerance were compared with the postoperative VAS pain score and morphine consumption. Forty women were enrolled. Their preoperative pressure pain threshold and tolerance were 141 +/- 65 kPa and 223 +/- 62 kPa, respectively. The VAS pain score in the postanesthesia care unit and at 24 h postoperatively were 81 +/- 24 and 31 +/- 10, respectively. Highly anxious patients had higher VAS pain scores in the postanesthesia care unit (P pain tolerance was significantly correlated with the VAS at 24 h postoperatively (P pain tolerance after fentanyl administration (mean, 272 +/- 68 kPa) correlated significantly with morphine consumption in the first 24 h postoperatively (P pain tolerance is significantly correlated with the level of postoperative pain. Pain tolerance assessment after fentanyl was administered and fentanyl sensitivity predicted the dose of analgesics used in the first 24 h after surgery. The algometer is thus a simple, useful tool for predicting postoperative pain and analgesic consumption.

The aim of this study was to define the value of MRI of the pancreas for preoperative local staging of patients with a suspected pancreatic mass. Ninety-four patients (41 women, 53 men; age range 32-87 years) with a suspected pancreatic tumor underwent preoperative staging with MRI on a 1.5-T system. The MRI protocol included breath-hold MR cholangiopancreatography in turbo spin-echo technique, biphasic contrast-enhanced 3D MR angiography, and MRI of the upper abdomen with breath-hold T2-weighted half-Fourier acquired single-shot turbo spin-echo and T1-weighted fast-low-angle-shot (pre- and postcontrast) sequences. Data were collected prospectively and analyzed by two radiologists in agreement modality. Evaluation criteria were vascular involvement, resectability, and a characterization benign vs malignant. Results were compared to histopathology in 78 patients. Sixteen patients were followed-up. In 74 of 94 patients a solid tumor or an inflammation of the pancreas ( n=62) or the papilla ( n=12) was detected. In this group, MRI had a sensitivity of 98%, a specificity of 92%, and an accuracy of 96% in the characterization of malignant tumors. Regarding only the solid tumors, the positive predictive value of MRI was 87% with respect to resectability. Other pathologic findings included adenoma or inflammation of the duodenum ( n=5), carcinoma or benign stenosis of the choledochus duct ( n=7) and carcinoma of the gall bladder ( n=2). In 6 patients MRI did not depict any pathologic findings, and follow-up confirmed this interpretation. Magnetic resonance imaging allows a local preoperative staging in patients with suspected pancreatic tumor. Limitations, however, concern to the diagnostics of peritoneal and/or liver metastases.

Preoperative chemoradiotherapy has been widely used for the prevention of local recurrence of locally advanced rectal cancer, and the effect of chemoradiotherapy is known to be associated with overall survival. We aimed to evaluate the association of the pathologic response grade with tumor recurrence rate after chemoradiotherapy, using radiographic analysis and the Response Evaluation Criteria in Solid Tumors as the parameters. This study was conducted at a single tertiary care institution in Japan. This was a retrospective cohort study of patients undergoing preoperative chemoradiotherapy. A total of 101 low rectal cancer patients receiving preoperative chemoradiotherapy from July 2004 to August 2012 were enrolled. The tumor reduction rate was measured with the use of traditional Response Evaluation Criteria in Solid Tumors, barium enema, and CT volumetry, and the correlation between the reduction rate and the pathologic response grade was examined. The tumor reduction rate assessed according to Response Evaluation Criteria in Solid Tumors showed no association with the pathologic response grade (p =0.61). In contrast, the radiographic response rate by both barium enema and CT volumetry strongly correlated with the pathologic response grade (p volumetry had a lower recurrence rate (p =0.03, p =0.03, p =0.0002, and p =0.001). The difference between high responders and low responders was especially prominent by barium enema and CT volumetry. The study is limited by its retrospective nature. Double-contrast barium enema and CT volumetry were superior to Response Evaluation Criteria in Solid Tumors in evaluating the effect of chemoradiotherapy and predicting the likelihood of tumor recurrence.

To evaluate the effect of preoperative oral ibuprofen (IBU) on the success of inferior alveolar nerve blocks (IANBs) with mepivacaine containing 1 : 100 000 epinephrine for patients with symptomatic irreversible pulpitis (SIP). The present study was a double-blind, randomized, placebo-controlled clinical trial. The study included two study groups each consisting of 25 patients who exhibited symptomatic irreversible pulpitis of a mandibular posterior tooth. The patients presented prolonged moderate or severe pain (>10 s) after cold testing and indicated their pain scores on a Heft-Parker visual analogue scale. The patients received identically appearing capsules containing either 600 mg IBU (IBUg) or gelatin (placebo, PLAg) 1 h before administration of IANB with 2% mepivacaine containing 1 : 100 000 epinephrine. After 15 min, the anaesthetic blockade was assessed by a three-step examination (lip numbness, positive/negative response to cold testing and clinical discomfort during endodontic access). IANB success was defined as the absence of pain during any of these evaluations. The data were analysed using the chi-squared test. All of the patients reported moderate or severe pain before the preoperative procedure. Statistically significant differences were observed between the IBUg and PLAg (P < 0.05); the success rates for the IANB were 72% (IBUg) and 36% (PLAg). Preoperative oral administration of IBU significantly improved the efficacy of IANB in patients with symptomatic irreversible pulpitis. © 2013 International Endodontic Journal.

It is recommended that arteriovenous fistula (AVF) blood flow should be more than 425 ml/min before cannulation. However, the relationship between preoperative radial artery flow (RAF) and postoperative AVF blood flow has still not been examined. Sixty-one patients with end-stage kidney disease (ESKD) were examined. They had an AVF prepared at Juntendo University Hospital from July 2006 through August 2007. Preoperative RAF and postoperative AVF blood flows were measured by ultrasonography. AVF blood flow gradually increased after the operation. AVF blood flow was significantly correlated with preoperative RAF. When preoperative RAF exceeded 21.4 ml/min, AVF blood flow rose to more than 425 ml/min. The postoperative AVF blood flow in the group with RAF of more than 20 ml/min was significantly higher than that in those with less than 20 ml/min. Preoperative RAF of less than 20 ml/min had a significantly high risk of primary AVF failure within 8 months compared with that of more than 20 ml/min. It appears that measurement of RAF by ultrasonography is useful for estimating AVF blood flow postoperatively and can predict the risk of complications in ESKD patients.

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.

Few investigations preoperatively are important for low-risk patients. This study was designed to determine the level of compliance with preoperative investigation guidelines for ASA I patients undergoing elective surgery. Secondary objectives included the following: to identify common inappropriate investigations, to evaluate the impact of abnormal testing on patient management, to determine factors affecting noncompliant tests, and to estimate unnecessary expenditure. This retrospective study was conducted on adult patients over a one-year period. The institute's guidelines recommend tests according to the patients' age groups: a complete blood count (CBC) for those patients aged 18-45; CBC, chest radiograph (CXR) and electrocardiography (ECG) for those aged 46-60; and CBC, CXR, ECG, electrolytes, blood glucose, blood urea nitrogen (BUN), and creatinine (Cr) for patients aged 61-65. The medical records of 1,496 patients were reviewed. Compliant testing was found in only 12.1% (95% CI, 10.5-13.9). BUN and Cr testings were the most frequently overprescribed tests. Overinvestigations tended to be performed on major surgery and younger patients. Overall, overinvestigation incurred an estimated cost of US 200,000 dollars during the study period. The need to utilize the institution's preoperative guidelines should be emphasized in order to decrease unnecessary testing and the consequential financial burden.

Metastatic brain tumors are the most common brain tumors in adults. Patients with metastatic brain tumors have poor prognoses with median survival of 6-12 months. Seizures are a major presenting symptom and cause of morbidity and mortality. In this article, risk factors for the onset of preoperative seizures and postoperative seizure control are examined. Adult patients who underwent resection of one or more brain metastases at a single institution between 1998 and 2011 were reviewed retrospectively. Of 565 patients, 114 (20.2%) patients presented with seizures. Factors independently associated with preoperative seizures were preoperative headaches (P = 0.044), cognitive deficits (P = 0.031), more than 2 intracranial metastatic tumors (P = 0.013), temporal lobe location (P = 0.031), occipital lobe location (P = 0.010), and bone involvement by tumor (P = 0.029). Factors independently associated with loss of seizure control after surgical resection were preoperative seizures (P = 0.001), temporal lobe location (P = 0.037), lack of postoperative chemotherapy (P = 0.010), subtotal resection of tumor (P = 0.022), and local recurrence (P = 0.027). At last follow-up, the majority of patients (93.8%) were seizure-free. Thirty patients (5.30%) in total had loss of seizure control, and only 8 patients (1.41%) who did not have preoperative seizures presented with new-onset seizures after surgical resection of their metastases. The brain is a common site for metastases from numerous primary cancers, such as breast and lung. The identification of factors associated with onset of preoperative seizures as well as seizure control postoperatively could aid management strategies for patients with metastatic brain tumors. Patients with preoperative seizures who underwent resection tended to have good seizure control after surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

Purpose: To compare preoperative chemotherapy (ChT) and preoperative chemoradiotherapy (ChT-RT) in operable Stage III non-small-cell lung cancer. Methods and Materials: This retrospective study analyzed all patients with pathologically confirmed Stage III (N2) non-small-cell lung cancer who initiated preoperative ChT or ChT-RT at Duke University between 1995 and 2006. Mediastinal pathologic complete response (pCR) rates were compared using a chi-square test. The actuarial overall survival, disease-free survival, and local control were estimated using the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox regression analysis was also performed. Results: A total of 101 patients who initiated preoperative therapy with planned resection were identified. The median follow-up was 20 months for all patients and 38 months for survivors. The mediastinal lymph nodes were reassessed after preoperative therapy in 88 patients (87%). Within this group, a mediastinal pCR was achieved in 35% after preoperative ChT vs. 65% after preoperative ChT-RT (p = 0.01). Resection was performed in 69% after ChT and 84% after ChT-RT (p = 0.1). For all patients, the overall survival, disease-free survival, and local control rate at 3 years was 40%, 27%, and 66%, respectively. No statistically significant differences were found in the clinical endpoints between the ChT and ChT-RT subgroups. On multivariate analysis, a mediastinal pCR was associated with improved disease-free survival (p = 0.03) and local control (p = 0.03), but not overall survival (p = 0.86). Conclusion: Preoperative ChT-RT was associated with higher mediastinal pCR rates but not improved survival.

Preoperative atrial fibrillation (AF) is associated with increased morbidity and mortality after open heart surgery. However, the impact of preoperative AF on long-term survival after open heart surgery has not been widely examined in rural populations. Patients from rural regions are less likely to receive treatment for cardiac conditions and to have adequate medical insurance coverage. To examine the influence of preoperative AF on long-term survival following open heart surgery in rural eastern North Carolina. Long-term survival was compared in patients with and without preoperative AF after coronary artery bypass grafting (CABG) and CABG plus valve (CABG + V) surgery between 2002 and 2011. Hazard ratios (HR) and 95% confidence intervals (CI) were computed using a Cox regression model. The study population consisted of 5438 patients. A total of 263 (5%) patients had preoperative AF. Preoperative AF was an independent predictor of long-term survival (open heart surgery: adjusted HR = 1.6, 95% CI = 1.3-2.0; CABG: adjusted HR = 1.6, 95% CI = 1.3-2.1; CABG + V: adjusted HR = 1.6, 95% CI = 1.1-2.3). Preoperative AF is an important predictor of long-term survival after open heart surgery in this rural population. Copyright © 2013 Elsevier Inc. All rights reserved.

To decrease the risk of postoperative complication, improving general and pulmonary conditioning preoperatively should be considered essential for patients scheduled to undergo lung surgery. The aim of this study is to develop a short-term beneficial program of preoperative pulmonary rehabilitation for lung cancer patients. From June 2009, comprehensive preoperative pulmonary rehabilitation (CHPR) including intensive nutritional support was performed prospectively using a multidisciplinary team-based approach. Postoperative complication rate and the transitions of pulmonary function in CHPR were compared with historical data of conventional preoperative pulmonary rehabilitation (CVPR) conducted since June 2006. The study population was limited to patients who underwent standard lobectomy. Postoperative complication rate in the CVPR (n = 29) and CHPR (n = 21) were 48.3% and 28.6% (p = 0.2428), respectively. Those in patients with Charlson Comorbidity Index scores ≥2 were 68.8% (n = 16) and 27.3% (n = 11), respectively (p = 0.0341) and those in patients with preoperative risk score in Estimation of Physiologic Ability and Surgical Stress scores >0.3 were 57.9% (n = 19) and 21.4% (n = 14), respectively (p = 0.0362). Vital capacities of pre- and post intervention before surgery in the CHPR group were 2.63±0.65 L and 2.75±0.63 L (p = 0.0043), respectively; however, their transition in the CVPR group was not statistically significant (p = 0.6815). Forced expiratory volumes in one second of pre- and post intervention before surgery in the CHPR group were 1.73±0.46 L and 1.87±0.46 L (p = 0.0012), respectively; however, their transition in the CVPR group was not statistically significant (p = 0.6424). CHPR appeared to be a beneficial and effective short-term preoperative rehabilitation protocol, especially in patients with poor preoperative conditions.

Full Text Available Antifibrinolytic agents are used during cardiac surgery to minimize bleeding and reduce exposure to blood products. Several reports suggest that tranexamic acid (TA can induce seizure activity in the postoperative period. To examine factors associated with postoperative seizures in patients undergoing cardiac surgery who received TA. University-affiliated hospital. Case-control study. Patients undergoing cardiac surgery with cardiopulmonary bypass (CPB between January 2008 and December 2009 were identified. During this time, all patients undergoing heart surgery with CPB received TA. Cases were defined as patients who developed seizures that required initiation of anticonvulsive therapy within 48 h of surgery. Exclusion criteria included subjects with preexisting epilepsy and patients in whom the convulsive episode was secondary to a new ischemic lesion on brain imaging. Controls who did not develop seizures were randomly selected from the initial cohort. From an initial cohort of 903 patients, we identified 32 patients with postoperative seizures. Four patients were excluded. Twenty-eight cases and 112 controls were analyzed. Cases were more likely to have a history of renal impairment and higher preoperative creatinine values compared with controls (1.39 ± 1.1 vs. 0.98 ± 0.02 mg/dL, P = 0.02. Significant differences in the intensive care unit, postoperative and total lengths of stay were observed. An association between high preoperative creatinine value and postoperative seizure was identified. TA may be associated with the development of postoperative seizures in patients with renal dysfunction. Doses of TA should be reduced or even avoided in this population.

Full Text Available Background and objective Postoperative pulmonary complications (PPCs, especially postoperative pneumonia (POP, directly affect the rapid recovery of lung cancer patients after surgery. Peak expiratory flow (PEF can reflect airway patency and cough efficiency. Moreover, cough impairment may lead to accumulation of pulmonary secretions which can increase the risk of PPCs. The aim of this study is to investigate the effect of preoperative PEF on PPCs in patients with lung cancer. Methods Retrospective research was conducted on 433 lung cancer patients who underwent lobectomy at the West China Hospital of Sichuan University from January 2014 to December 2015. The associations between preoperative PEF and PPCs were analyzed based on patients’ basic characteristics and clinical data in hospital. Results Preoperative PEF value in PPCs group (280.93±88.99 L/min was significantly lower than that in non-PPCs group (358.38±93.69 L/min (P320 L/min group (9.4%(P<0.001. Conclusion Preoperative PEF and PPCs are correlated, and PEF may be used as a predictor of PPCs.

Highlights: • Preoperative MRI displays additional disease in 10.4% of cases in patients with infiltrating ductal carcinoma. • In cases with a complex intraductal-associated component, MRI is helpful in managing the surgical approach, and can potentially reduce reoperation rates. • Preoperative MRI showed a 91.9% agreement with the final histology, but core-needle biopsy cannot be rejected, so as to limit unnecessary surgery. • When MRI shows additional disease, there is often a change in the initial surgical plan. • Evolving surgery techniques, such as oncoplastic procedures, can be safely performed as an alternative to mastectomy in some patients. - Abstract: Objective: The last few years have witnessed a significant increase in the preoperative use of Magnetic Resonance Imaging (MRI) for staging purposes in breast cancer (BC) patients. Many studies have confirmed the improvement that MRI can provide in terms of diagnostic assessment, especially with regard to additional disease foci. In the present study, we address the advantages and disadvantages of MRI in the preoperative setting for BC patients. Patients and methods: There were 1513 consecutive breast MRI studies performed in patients with either primary or recurrent BC, who were scheduled for surgery. Results: Beyond the primary lesion, 10.4% of our cases had additional disease at the final histological assessment. MRI overall sensitivity, when considering tumour size and additional foci together, was 74.3%, and 80.3% when considering additional foci exclusively. MRI specificity for additional disease was 95.3%, positive predictive value was 77.4%, and negative predictive value was 94.6%. Nevertheless, 5% of cases had additional tumours that were missed by MRI or, conversely, had additional foci on MRI that were not confirmed by histology. Age (p = 0.020) and lobular carcinomas (p = 0.030) showed significance in the multivariate analysis by logistic regression, using the presence of additional

Full Text Available Shenelle A Edwards-Hampton,1 Sharlene Wedin2 1Department of General Surgery, Wake Forest Baptist Medical Center, Medical Center Boulevard, Winston-Salem, NC, 2Department of Psychiatry and Behavioral Sciences, Medical University of South Carolina, Charleston, SC, USA Abstract: Preoperative psychosocial assessment is the standard of care for patients seeking weight-loss surgery (WLS. However, the assessment procedure varies widely by surgery site. Comprehensive assessments can provide a wealth of information that assists both the patient and the treatment team, anticipate and prepare for challenges associated with extensive behavioral and lifestyle changes that are required postsurgery. In this review, we provide an overview of the purpose of the preoperative psychosocial assessment and domains to be included. Challenges commonly identified in the assessment are discussed, including maladaptive eating behaviors, psychiatric comorbidities, and alcohol use. Potential solutions and approaches to these challenges are provided. Additionally, patient populations requiring special consideration are presented to include adolescents, those with cognitive vulnerabilities, and aging adults.

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.

Full Text Available Objective: The infections caused by human immunodeficiency virus (HIV, hepatitis B (HBV and C (HCV viruses pose a serious occupational risk for the healthcare workers especially those in emergency services, laboratories and surgery wards. Vaccination and establishment of the strict biosafety procedures are the main principles to prevent blood-borne infections in healthcare workers. Additionally, serological screening of the preoperative patients could decrease the risk for exposure. In this study, we aimed to determine the seroprevalence of HBsAg, anti-HCV, anti-HIV 1/2 in preoperative patients. Methods: Hospital automation records were evaluated retrospectively for 4.367 patients who were scheduled for surgery and scanned for anti-HIV 1/2, HBsAg and anti-HCV as preoperative procedures in the preparation period of operation between January 2012 and December 2012. Results: HBsAg positivity rate was found in 7.7% (n=336, anti-HCV positivity rate was found in 2.3% (n=101. A two (0.05% of five patients were positive for anti-HIV 1/2 was found positive verification test and the other three samples were accepted as false positive test results. Conclusion: All healthcare workers must be trained about occupational diseases and vaccinated against Hepatitis B. Universal precautions must be strictly followed particularly in the operating room. In addition, all patients should be considered as potential carriers regarded as a carrier of the potential for infection. J Clin Exp Invest 2013; 4 (4: 449-452

Maxillary growth in patients with cleft lip and palate is highly variable. The authors' aim was to investigate associations between preoperative cleft lip measurements and maxillary growth determined cephalometrically in patients with complete unilateral cleft lip and palate (cUCLP). Retrospective cross-sectional study. Children with cUCLP. Preoperative cleft lip measurements were made at the time of primary cheiloplasty and available for each patient. Maxillary growth was evaluated on lateral cephalometric radiographs taken prior to any orthodontic treatment and alveolar bone grafting (8.5 ± 0.7 years). The presence of associations between preoperative cleft lip measurements and cephalometric measures of maxillary growth was determined using regression analyses. In the 58 patients included in the study, the cleft lateral lip element was deficient in height in 90% and in transverse width in 81% of patients. There was an inverse correlation between cleft lateral lip height and transverse width with a β coefficient of -0.382 (P = .003). Patients with a more deficient cleft lateral lip height displayed a shorter maxillary length (β coefficient = 0.336; P = .010), a less protruded maxilla (β coefficient = .334; P = .008), and a shorter anterior maxillary height (β coefficient = 0.306; P = .020) than those with a less deficient cleft lateral lip height. Patients with cUCLP present with varying degrees of lateral lip hypoplasia. Preoperative measures of lateral lip deficiency are related to later observed deficiencies of maxillary length, protrusion, and height.

Full Text Available Introduction. Surgery-induced oxidative stress increases the risk of perioperative complications and delay in postoperative recovery. In mice, short-term preoperative dietary and protein restriction protect against oxidative stress. We investigated the feasibility of a calorie- and protein-restricted diet in two patient populations. Methods. In this pilot study, 30 live kidney donors and 38 morbidly obese patients awaiting surgery were randomized into three groups: a restricted diet group, who received a synthetic liquid diet with 30% fewer calories and 80% less protein for five consecutive days; a group who received a synthetic diet containing the daily energy requirements (DER; and a control group. Feasibility was assessed using self-reported discomfort, body weight changes, and metabolic parameters in blood samples. Results. Twenty patients (71% complied with the restricted and 13 (65% with the DER-diet. In total, 68% of the patients reported minor discomfort that resolved after normal eating resumed. The mean weight loss on the restricted diet was significantly greater (2.4 kg than in the control group (0 kg, p = 0.002, but not in the DER-diet (1.5 kg. The restricted diet significantly reduced levels of serum urea and plasma prealbumin (PAB and retinol binding protein (RBP. Conclusions. A short-term preoperative calorie- and protein-restricted diet is feasible in kidney donors and morbidly obese patients. Compliance is high and can be objectively measured via changes in urea, PAB, and RBP levels. These results demonstrate that this diet can be used to study the effects of dietary restriction on surgery-induced oxidative stress in a clinical setting.

Methods Patients with gastroesophageal (GE junction (Siewert type II and III or gastric adenocarcinoma who underwent neoadjuvant CRT followed by planned surgical resection at Duke University between 1987 and 2009 were reviewed. Overall survival (OS, local control (LC and disease-free survival (DFS were estimated using the Kaplan-Meier method. Toxicity was graded according to the Common Toxicity Criteria for Adverse Events version 4.0. Results Forty-eight patients were included. Most (73% had proximal (GE junction, cardia and fundus tumors. Median radiation therapy dose was 45 Gy. All patients received concurrent chemotherapy. Thirty-six patients (75% underwent surgery. Pathologic complete response and R0 resection rates were 19% and 86%, respectively. Thirty-day surgical mortality was 6%. At 42 months median follow-up, 3-year actuarial OS was 40%. For patients undergoing surgery, 3-year OS, LC and DFS were 50%, 73% and 41%, respectively. Conclusions Preoperative CRT for gastric cancer is well tolerated with acceptable rates of perioperative morbidity and mortality. In this patient cohort with primarily advanced disease, OS, LC and DFS rates in resected patients are comparable to similarly staged, adjuvantly treated patients in randomized trials.

Background Patients with obstructive jaundice have various pathophysiological changes that affect the liver, kidney, heart, and the immune system. There is considerable controversy as to whether temporary relief of biliary obstruction prior to major definitive surgery (pre-operative biliary drainage) is of any benefit to the patient. Objectives To assess the benefits and harms of pre-operative biliary drainage versus no pre-operative biliary drainage (direct surgery) in patients with obstructive jaundice (irrespective of a benign or malignant cause). Search methods We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Clinical Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2012. Selection criteria We included all randomised clinical trials comparing biliary drainage followed by surgery versus direct surgery, performed for obstructive jaundice, irrespective of the sample size, language, and publication status. Data collection and analysis Two authors independently assessed trials for inclusion and extracted data. We calculated the risk ratio (RR), rate ratio (RaR), or mean difference (MD) with 95% confidence intervals (CI) based on the available patient analyses. We assessed the risk of bias (systematic overestimation of benefit or systematic underestimation of harm) with components of the Cochrane risk of bias tool. We assessed the risk of play of chance (random errors) with trial sequential analysis. Main results We included six trials with 520 patients comparing pre-operative biliary drainage (265 patients) versus no pre-operative biliary drainage (255 patients). Four trials used percutaneous transhepatic biliary drainage and two trials used endoscopic sphincterotomy and stenting as the method of pre-operative biliary drainage. The risk of bias was high in all trials. The proportion of patients with malignant obstruction varied between 60

Immediate preoperative enteral nutrition (preoperative enteral nutrition

2017-01-01

Full Text Available Nutritional support of surgical patients is a necessary part of the treatment. It alone cannot cure the disease but it significantly affects the recovery of patients and supports surgical interventions. Patients in malnutrition have shown to have significantly more postoperative infectious and non-infectious complications. This significantly prolongs treatment time and increases costs. However, there is one fact that cannot be expressed in money, which is the patient's impression of the surgical intervention. Adequate preoperative patient support, based on the intake of liquid nutritive solutions, reduces preoperative stress and deflects the metabolic response. Now, it is recommended for adults and children older than one year to drink clear liquid up to 2 hours before induction in anesthesia. Appropriate enteral nutrition has a significant place in the postoperative recovery of patients. Enteral nutrition is reducing complications, mainly infectious complications because the function of the digestive system as one large immune system is preserved. Perioperative enteral nutrition is a necessary part of the modern treatment of surgical patients. In addition to the significant effect on the occurrence of postoperative complications, it is also important that this type of diet improves the psychological status of patients.

Introduction Patients and their families are understandably anxious about the risk of complications and unfamiliar experiences following cardiac surgery. Providing information about postoperative care in the intensive care unit (ICU) to patients and families may lead to lower anxiety levels, and increased satisfaction with healthcare. The objectives of this study are to evaluate the effectiveness of preoperative patient education provided for patients undergoing elective cardiac surgery. Methods and analysis 100 patients undergoing elective coronary artery bypass graft, with or without valve replacement surgery, will be recruited into a 2-group, parallel, superiority, double-blinded randomised controlled trial. Participants will be randomised to either preoperative patient education comprising of a video and ICU tour with standard care (intervention) or standard education (control). The primary outcome measures are the satisfaction levels of patients and family members with ICU care and decision-making in the ICU. The secondary outcome measures are patient anxiety and depression levels before and after surgery. Ethics and dissemination Ethical approval has been obtained from the Joint Chinese University of Hong Kong—New Territories East Cluster Clinical Research Ethics Committee (reference number CREC 2015.308). The findings will be presented at conferences and published in peer-reviewed journals. Study participants will receive a 1-page plain language summary of results.

To analyze the operative benefit of preoperative sclerotherapy of facial venous malformations and assess long-term patient outcome. Preoperative sclerotherapy was performed in 24 consecutive patients referred before resection of facial venous malformation. Pretreatment imaging was reviewed for malformation dimensions (length, width, and height), and volumes were estimated. Sclerotherapy was performed with 3% sodium tetradecyl in the first 15 patients and 98% dehydrated alcohol in the remaining 9 patients. Operative blood loss, operative time, transfusion requirement, and hospital stay were recorded. Operative time per lesion volume and operative blood loss per lesion volume were calculated. Results were compared with 15 historical control patients who underwent resection of facial venous malformations without preoperative sclerotherapy. Long-term follow-up of study and control patients was performed. Compared with controls, patients undergoing preoperative venous sclerotherapy were significantly older (P = .0206) and had larger lesions in all three dimensions (height, P = .0002; length, P = .0010; width, P = .0004). Patients receiving sclerotherapy had shorter operative time per lesion volume (P lesion volume (P nerve paresis occurred in 8.3% of cases. Long-term follow-up revealed retreatment was required in 2 of 24 patients (8.3%). Preoperative sclerotherapy of venous malformations was associated with less operative time per lesion volume and less operative blood loss per lesion volume. Long-term follow-up revealed a low need for retreatment. Copyright © 2011 SIR. Published by Elsevier Inc. All rights reserved.

The reported overall accuracy of MRI in predicting the pathologic stage of nonirradiated rectal cancer is high. However, the role of MRI in restaging rectal tumors after neoadjuvant CRT is contentious. Thus, we evaluate the accuracy of restaging magnetic resonance imaging (MRI) for rectal cancer patients who receive preoperative chemoradiotherapy (CRT). We analyzed 150 patients with locally advanced rectal cancer (T3-4N0-2) who had received preoperative CRT. Pre-CRT MRI was performed for local tumor and nodal staging. All patients underwent restaging MRI followed by total mesorectal excision after the end of radiotherapy. The primary endpoint of the present study was to estimate the accuracy of post-CRT MRI as compared with pathologic staging. Pathologic T classification matched the post-CRT MRI findings in 97 (64.7%) of 150 patients. 36 (24.0%) of 150 patients were overstaged in T classification, and the concordance degree was moderate (k=0.33, prectal cancer patients who received preoperative CRT. The diagnostic accuracy of restaging MRI is relatively high in rectal cancer patients who achieved clinical downstaging after CRT. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

The objective of this study was to assess the gait variability of lumbar spinal stenosis (LSS) patients and to evaluate its postoperative progression. The hypothesis was that LSS patients' preoperative gait variability in the frequency domain was higher than the corresponding postoperative. A tri-axial accelerometer sensor was used for the gait measurement and a spectral differential entropy algorithm was used to measure the gait variability. Twelve subjects with LSS were measured before and after surgery. Preoperative measurements were performed 2 days before surgery. Postoperative measurements were performed 6 and 12 months after surgery. Preoperative gait variability was higher than the corresponding postoperative. Also, in most cases, gait variability appeared to decrease throughout the year

Preoperative testing and risk assessment: perspectives on patient selection in ambulatory anesthetic procedures

Full Text Available Tracey L Stierer,1,2 Nancy A Collop3,41Department of Anesthesiology, 2Department of Critical Care Medicine, Otolaryngology Head and Neck Surgery, Johns Hopkins Medicine, Baltimore, MD, USA; 3Department of Medicine, 4Department of Neurology, Emory University, Emory Sleep Center, Wesley Woods Center, Atlanta, GA, USAAbstract: With recent advances in surgical and anesthetic technique, there has been a growing emphasis on the delivery of care to patients undergoing ambulatory procedures of increasing complexity. Appropriate patient selection and meticulous preparation are vital to the provision of a safe, quality perioperative experience. It is not unusual for patients with complex medical histories and substantial systemic disease to be scheduled for discharge on the same day as their surgical procedure. The trend to “push the envelope” by triaging progressively sicker patients to ambulatory surgical facilities has resulted in a number of challenges for the anesthesia provider who will assume their care. It is well known that certain patient diseases are associated with increased perioperative risk. It is therefore important to define clinical factors that warrant more extensive testing of the patient and medical conditions that present a prohibitive risk for an adverse outcome. The preoperative assessment is an opportunity for the anesthesia provider to determine the status and stability of the patient’s health, provide preoperative education and instructions, and offer support and reassurance to the patient and the patient’s family members. Communication between the surgeon/proceduralist and the anesthesia provider is critical in achieving optimal outcome. A multifaceted approach is required when considering whether a specific patient will be best served having their procedure on an outpatient basis. Not only should the patient's comorbidities be stable and optimized, but details regarding the planned procedure and the resources available

This study aimed to find out whether preoperative diffusion tensor imaging (DTI) and probabilistic tractography could help with surgical planning for deep brain stimulation in the periaqueductal/periventricular grey area (PAG/PVG) in a patient with lower leg stump pain. A preoperative DTI was obtained from the patient, who then received DBS surgery in the PAG/PVG area with good pain relief. The postoperative MRI scan showing electrode placement was used to calculate four seed areas to represent the contacts on the Medtronic 3387 electrode. Probabilistic tractography was then performed from the pre-operative DTI image. Tracts were seen to connect to many areas within the pain network from the four different contacts. These initial findings suggest that preoperative DTI scanning and probabilistic tractography may be able to assist surgical planning in the future.

The aim of this prospective double-blind randomized study was to compare the effectiveness of preoperative dexketoprofen trometamol for acute postoperative pain in patients undergoing minor outpatient urologic surgery. Sixty male patients (ASA I and II) undergoing varicocelectomy and testicular sperm extraction (TESE) with standard laryngeal mask airway (LMA) anesthesia were randomly divided into two groups. Patients in Group I (n=30) received 50 mg of dexketoprofen trometamol iv before induction, whereas patients in Group II (n=30) received saline. All patients received standard LMA anesthesia (propofol, sevoflurane and N2O/O2). Analgesic efficacy was evaluated by self-assessment of pain intensity (VAS) at regular intervals. Vital signs, side effects and time to reach a postanesthesia discharge score (PADS) of ≥9 were also recorded. Paracetamol 1 gr iv and tramadol 100 mg iv were used for rescue analgesia. Demographic data and duration of surgery were similar in both groups. There was no significant difference between groups with respect to postoperative pain scores and side effects. Although more patients in Group II (60%) required rescue analgesia compared to Group I (33.3%), the difference did not reach statistical significance. Preoperative IV use of dexketoprofen trometamol iv did not decrease the need for rescue analgesia in patients undergoing minor outpatient urological surgery.

Major burn injury patients commonly fast preoperatively before multiple surgical procedures. The Societies of Anesthesiology in Europe and the United States recommend fasting from clear fluids for two hours and solids for six to eight hours preoperatively. However, at the Royal Adelaide Hospital, patients often fast from midnight proceeding the day of surgery. This project aims to promote evidence-based practice to minimize extended preoperative fasting in major burn patients. A baseline audit was conducted measuring the percentage compliance with audit criteria, specifically on preoperative fasting documentation and appropriate instructions in line with evidence-based guidelines. Strategies were then implemented to address areas of non-compliance, which included staff education, development of documentation tools and completion of a perioperative feeding protocol for major burn patients. Following this, a post implementation audit assessed the extent of change compared with the baseline audit results. Education on evidence-based fasting guidelines was delivered to 54% of staff. This resulted in a 19% improvement in compliance with fasting documentation and a 52% increase in adherence to appropriate evidence-based instructions. There was a notable shift from the most common fasting instruction being "fast from midnight" to "fast from 03:00 hours", with an overall four-hour reduction in fasting per theater admission. These results demonstrate that education improves compliance with documentation and preoperative fasting that is more reflective of evidence-based practice. Collaboration with key stakeholders and a hospital wide fasting protocol is warranted to sustain change and further advance compliance with evidence-based practice at an organizational level.

Full Text Available We investigated the relationship between preoperative comorbidity and postoperative survival after intestinal transplantation. Each patient received a score for preoperative comorbidity. Each comorbidity was given a score based on the degree it impaired function (score range 0–3. A total score was derived from the summation of individual comorbidity scores. Patients (72 adults (M : F, 33 : 39 received an isolated intestinal graft (27 or a cluster graft (45. Mean (standard deviation survival was 1501 (1444 days. The Kaplan-Meier analysis revealed a significant inverse association between survival and comorbidity score (logrank test for trend, . Patients grouped into comorbidity scores of 0 and 1, 2 and 3, 4 and 5, 6, and above had hazard ratios (95% confidence intervals for death (compared to group 0 + 1, which increased with comorbidity scores: 1.945 (0.7622–5.816, 5.075 (3.314–36.17, and 13.77 (463.3–120100, respectively, (. Receiver-operator curves at 1, 3, 5, and 10 years postoperative had “C” statistics of 0.88, 0.85, 0.88, and 0.92, respectively. When evaluating patients for transplantation, the degree of comorbidity should be considered as a major factor influencing postoperative survival.

Full Text Available Background. Few investigations preoperatively are important for low-risk patients. This study was designed to determine the level of compliance with preoperative investigation guidelines for ASA I patients undergoing elective surgery. Secondary objectives included the following: to identify common inappropriate investigations, to evaluate the impact of abnormal testing on patient management, to determine factors affecting noncompliant tests, and to estimate unnecessary expenditure. Methods. This retrospective study was conducted on adult patients over a one-year period. The institute’s guidelines recommend tests according to the patients’ age groups: a complete blood count (CBC for those patients aged 18–45; CBC, chest radiograph (CXR and electrocardiography (ECG for those aged 46–60; and CBC, CXR, ECG, electrolytes, blood glucose, blood urea nitrogen (BUN, and creatinine (Cr for patients aged 61–65. Results. The medical records of 1,496 patients were reviewed. Compliant testing was found in only 12.1% (95% CI, 10.5–13.9. BUN and Cr testings were the most frequently overprescribed tests. Overinvestigations tended to be performed on major surgery and younger patients. Overall, overinvestigation incurred an estimated cost of US 200,000 dollars during the study period. Conclusions. The need to utilize the institution’s preoperative guidelines should be emphasized in order to decrease unnecessary testing and the consequential financial burden.

Objectives  This study aimed at evaluating facial nerve outcomes in vestibular schwannoma patients presenting with preoperative facial nerve palsy. Design  A retrospective review. Setting  Single-institution cohort. Participants  Overall, 368 consecutive patients underwent vestibular schwannoma resection. Patients with prior microsurgery or radiosurgery were excluded. Main Outcome Measures  Incidence, House-Brackmann grade. Results  Of 368 patients, 9 had confirmed preoperative facial nerve dysfunction not caused by prior treatment, for an estimated incidence of 2.4%. Seven of these nine patients had Koos grade 4 tumors. Mean tumor diameter was 3.0 cm (range: 2.1-4.4 cm), and seven of nine tumors were subtotally resected. All nine patients were followed up clinically for ≥ 6 months. Of the six patients with a preoperative House-Brackmann grade of II, two improved to grade I, three were stable, and one patient worsened to grade III. Of the three patients with grade III or worse, all remained stable at last follow-up. Conclusions  Preoperative facial nerve palsy is rare in patients with vestibular schwannoma; it tends to occur in patients with relatively large lesions. Detailed long-term outcomes of facial nerve function after microsurgical resection for these patients have not been reported previously. We followed nine patients and found that eight (89%) of the nine patients had either stable or improved facial nerve outcomes after treatment. Management strategies varied for these patients, including rates of subtotal versus gross-total resection and the use of stereotactic radiosurgery in patients with residual tumor. These results can be used to help counsel patients preoperatively on expected outcomes of facial nerve function after treatment.

Full Text Available Purpose: We aimed to assess whether nerve-sparing radical prostatectomy (nsRP is associated with improved recovery of urinary continence compared to non–nerve-sparing radical prostatectomy (nnsRP in patients with localized prostate cancer and preoperative erectile dysfunction. Methods: A total of 360 patients with organ-confined prostate cancer and an International Index of Erectile Function score of less than 17 were treated with nsRP or nnsRP in Seoul St. Mary’s Hospital. Patients who received neoadjuvant or adjuvant androgen deprivation therapy or had a history of prostate-related surgery were excluded. Recovery of urinary continence was assessed at 0, 1, 3, 6, and 12 months. Postoperative recovery of continence was defined as zero pad usage. The association between nerve-sparing status and urinary continence was assessed by using univariate and multivariate Cox regression analyses after controlling for known predictive factors. Results: Urinary continence recovered in 279 patients (77.5% within the mean follow-up period of 22.5 months (range, 6–123 months. Recovery of urinary continence was reported in 74.6% and 86.4% of patients after nnsRP and nsRP, respectively, at 12 months (P=0.022. All groups had comparable perioperative criteria and had no significant preoperative morbidities. Age, American Society of Anesthesiologists score, and nerve-sparing status were significantly associated with recovery of urinary continence on univariate analysis. On multivariate analysis, age (hazard ratio [HR], 1.254; 95% confidence interval [CI], 1.002–1.478; P=0.026 and nerve-sparing status (HR, 0.713; 95% CI, 0.548–0.929; P=0.012 were independently associated with recovery of urinary continence. Conclusions: nsRP, as compared to nnsRP, improves recovery rates of urinary incontinence and decreases surgical morbidity without compromising pathologic outcomes.

Full Text Available OBJECTIVE: Enhancing immunologic responses, including human leukocyte antigen (HLA class I expression on tumor cells and recognition and elimination of tumor cells by tumor-specific cytotoxic T lymphocyte (CTL, is considered a novel concept of radiotherapy. The present study examined patients who underwent preoperative hyperthermo-chemoradiotherapy (HCRT for locally advanced rectal cancer to assess the correlation between HLA class I expression and clinical outcome. MATERIALS AND METHODS: Seventy-eight patients with locally advanced rectal adenocarcinoma who received preoperative HCRT were enrolled. The median age of the patients was 64 years (range, 33-85 years and 4, 18, and 56 patients had clinical stage I, II and III disease, respectively. Formalin-fixed and paraffin-embedded tissues excised before and after HCRT were subjected to immunohistochemical analysis with an anti-HLA class I-A, B, C antibody. HLA class I expression was graded according to tumor cell positivity. RESULTS: In pre-HCRT, the number of specimens categorized as Grade 0 and 1 were 19 (24% and 58 (74%, respectively. Only 1 patient (1% showed Grade 2 expression. However, 6 (8%, 27 (35%, 7 (9%, and 12 (15% post-HCRT specimens were graded as Grade 0, 1, 2, and 3, respectively. There was a significant increase in HLA class I expression in post-HCRT specimens (p<0.01. However, neither pre- nor post-HCRT HLA class I expression affected overall survival and distant metastasis-free survival in clinical stage III patients. Univariate analysis revealed that Post-HCRT HLA class I expression showed a significant negative relationship with LC (p<0.05. Nevertheless, multivariate analysis showed that there was no correlation between HLA class I expression and clinical outcome. CONCLUSION: HCRT increased HLA class I expression in rectal cancer patients. However, multivariate analysis failed to show any correlation between the level of HLA class I expression and prognosis.

The purpose of this study was to compare selected postoperative complications (including stomal and peristomal complications), hospital length of stay, and readmission rates in a group of patients who attended a preoperative educational intervention to a retrospective group of patients who did not receive the intervention. Retrospective, comparison cohort study. The intervention group comprised 124 patients who attended an educational session for persons with fecal ostomies at a single tertiary care center in the Northeastern United States. They were compared to findings from a group of 94 individuals who underwent ostomy surgery during a 1-year period before initiation of the class. Patients undergoing emergent procedures or who had previous stomas were excluded. We found no significant differences between the 2 cohorts with respect to age, gender, comorbidities, open versus minimally invasive procedures, or colorectal diagnoses. A preoperative 2-hour stoma education class was led by certified WOC nurses for all patients undergoing colorectal surgeries in which the creation of a stoma was anticipated. This session included a didactic portion outlining postoperative expectations in the management of new ostomies (including dietary changes, prevention of dehydration, and an overview of ostomy supplies), as well as a hands-on portion to practice stoma care skills. We compared postoperative complications within 30 days (particularly stoma-related complications, including pouch leakage due to loss of seal, and peristomal skin irritation) between the group attending the education session and the control group. We also compared length of stay and 30-day readmission rates. Patients who participated in the educational intervention experienced significantly fewer peristomal complications than did patients in the historic control group (44.7% vs 20.2%, P = .002). Logistic regression analysis revealed that participation in the group was associated with a lower likelihood of

To evaluate the treatment outcomes of patients with locally advanced rectal cancer treated with preoperative concurrent chemoradiotherapy (CCRT) or combined chemotherapy together with radiotherapy (CMTRT) without surgery. A total of 84 patients with locally advanced rectal adenocarcinoma (stage II or III) between January 1st, 2003 and December 31st, 2013 were enrolled, 48 treated with preoperative CCRT (Gr.I) and 36 with combined chemotherapy and radiotherapy (CMTRT) without surgery (Gr.II). The chemotherapeutic agents used concurrent with radiotherapy were either 5fluorouracil short infusion plus leucovorin and/or capecitabine or 5fluorouracil infusion alone. All patients received pelvic irradiation. There were 5 patients (10.4%) with a complete pathological response. The 3 yearoverall survival rates were 83.2% in Gr.I and 24.8 % in Gr.II (prectal cancer demonstrated that in preoperative CCRT a sphincter sparing procedure can be performed. The results of treatment with preoperative CCRT for locally advanced rectal cancer showed comparable rates of overall survival and sphincter sparing procedures as compared to previous studies.

The objective of this study was to evaluate roles of preoperative lymphoscintigraphy for sentinel lymph node biopsy in breast cancer patients. Five hundred and sixty-five consecutive breast cancer patients were prospectively randomized into groups with or without preoperative lymphoscintigraphy. In a group with lymphoscintigraphy, 238 patients had sentinel lymph nodes spotted in lymphoscintigram. The visualization of sentinel lymph nodes in lymphoscintigram was not associated with patients' age, primary tumor size and location, histopathologic type and time interval from injection of radiocolloid to lymphoscintigraphy. However, patients with axillary metastasis had a lower identification rate of sentinel lymph nodes by lymphoscintigraphy than those without metastasis (P=0.003). The identification rate of axillary sentinel lymph nodes was 99.3% in the group and the rate was similar whether there was sentinel lymph nodes spotted in axillary in lymphoscintigram or not (99.6% vs. 98.1%, P=0.327). The false-negative rate in this group was 4.2%. While in a group without lymphoscintigraphy, the identification rate and the false-negative rate were 99.6% and 4.8%, respectively. There was no significant difference between the two groups in the identification rate of axillary sentinel lymph nodes (P=0.594) and in the false-negative rate (P=1.00). Preoperative lymphoscintigraphy could neither improve the identification rate nor reduce the false-negative rate of breast cancer sentinel lymph node biopsy, and it is not necessary for sentinel lymph node biopsy in breast cancer patients.

Full Text Available BACKGROUND: To decrease the risk of postoperative complication, improving general and pulmonary conditioning preoperatively should be considered essential for patients scheduled to undergo lung surgery. OBJECTIVE: The aim of this study is to develop a short-term beneficial program of preoperative pulmonary rehabilitation for lung cancer patients. METHODS: From June 2009, comprehensive preoperative pulmonary rehabilitation (CHPR including intensive nutritional support was performed prospectively using a multidisciplinary team-based approach. Postoperative complication rate and the transitions of pulmonary function in CHPR were compared with historical data of conventional preoperative pulmonary rehabilitation (CVPR conducted since June 2006. The study population was limited to patients who underwent standard lobectomy. RESULTS: Postoperative complication rate in the CVPR (n = 29 and CHPR (n = 21 were 48.3% and 28.6% (p = 0.2428, respectively. Those in patients with Charlson Comorbidity Index scores ≥2 were 68.8% (n = 16 and 27.3% (n = 11, respectively (p = 0.0341 and those in patients with preoperative risk score in Estimation of Physiologic Ability and Surgical Stress scores >0.3 were 57.9% (n = 19 and 21.4% (n = 14, respectively (p = 0.0362. Vital capacities of pre- and post intervention before surgery in the CHPR group were 2.63±0.65 L and 2.75±0.63 L (p = 0.0043, respectively; however, their transition in the CVPR group was not statistically significant (p = 0.6815. Forced expiratory volumes in one second of pre- and post intervention before surgery in the CHPR group were 1.73±0.46 L and 1.87±0.46 L (p = 0.0012, respectively; however, their transition in the CVPR group was not statistically significant (p = 0.6424. CONCLUSIONS: CHPR appeared to be a beneficial and effective short-term preoperative rehabilitation protocol, especially in patients with poor preoperative conditions.

2018-06-01

The purpose of this study was to identify the incidence of preoperative venous thromboembolism (VTE), and determine if high energy hip fracture affects preoperative VTE occurrence. Three-hundred nine patients (244 low and 61 high energy injuries) treated between March 2015 and March 2017 were included in this study. Indirect multidetector computed tomographic venography for the detection of preoperative VTE was performed at admission. The incidence of preoperative VTE was compared between high and low energy injury hip fractures. Logistic regression analysis was used to identify independent risk factors for preoperative VTE. The overall incidence of preoperative VTE was 18.4% (56 of 305 patients). Preoperative VTE was identified in 17 (27.9%) and 39 (16.0%) patients in the high and low energy injury groups, respectively (p = 0.034). Multivariate logistic regression analysis showed that high energy injury, history of VTE, and myeloproliferative disease were significant predictive factors of preoperative VTE (OR = 2.451; 95% CI = 1.227-4.896, OR = 11.174; 95% CI = 3.500-35.673, OR = 6.936; 95% CI = 1.641-29.321, respectively) CONCLUSION: Because high energy hip fracture is significantly associated with preoperative VTE occurrence, preoperative evaluation and proper thromboprophylaxis should be performed for patients with a high-energy hip fracture.

To assess the potential value of preoperative {sup 18}F-FDG PET to predict postoperative recurrence of solitary localized primary gastrointestinal stromal tumour (GIST) after radical resection. A total of 46 patients with primary GIST who received preoperative {sup 18}F-FDG PET and underwent complete resection without neoadjuvant therapy were retrospectively studied. PET findings, including ring-shaped uptake and intense uptake, were compared with Joensuu risk grades using Fisher's exact test. The prognostic value of the preoperative clinico-imaging variables - age ≥60 years, male, ring-shaped uptake, intense uptake, tumour size >5 cm, heterogeneous CT attenuation and lower gastrointestinal origin - and Joensuu high risk for recurrence-free survival was evaluated using log-rank test and multivariate Cox regression analysis. Ring-shaped uptake and intense uptake were significantly associated with Joensuu high risk. Univariate analysis showed that ring-shaped uptake, intense uptake, size >5 cm and Joensuu high risk were significantly associated with inferior recurrence-free survival. Multivariate analysis showed that ring-shaped uptake (P = 0.004) and Joensuu high risk (P = 0.021) were independent adverse prognostic factors of postoperative recurrence. Ring-shaped uptake on preoperative {sup 18}F-FDG PET may be a potential predictor of postoperative tumour recurrence of localized primary GISTs. (orig.)

The aim of this study was to assess the preoperative nutritional status of patients undergoing thoracic surgery using different nutritional tools. . We conducted a prospective study on a sample of 43 thoracic patients, including 23 with neoplasms and 20 with non-neoplastic pathology who underwent thoracic surgery procedures between July-September 2011, in the Thoracic Surgery Clinic in Iaşi. Weight and height were measured and body mass index (BMI) was calculated. WHO classification for BMI categories was used. Preoperative serum level of transthyretin (TTR) and demographic data (gender, age) were also assessed. All patients were examined by the Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002). After performing SGA, 67.9% of the patients were well-nourished, 21.4% were moderately or suspected of being malnourished and 10.7% were severely malnourished. The level of TTR was significantly lower in the moderately or severely malnourished group, compared to those considered well-nourished. According to NRS-2002, 42.9% of the patients were considered at nutritional risk. The level of TTR of these patients was lower than the level of TTR of the patients without nutritional risk, but without statistical significance. Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002) are useful in identifying patients with nutritional risk, so that appropriate nutritional management could be initialised even before surgery.

To investigate, by a multi-institutional randomized trial, the prognostic significance of the augmentation of tumour-infiltrating lymphocytes (TILs) by preoperative intratumoral injection of OK-432 (OK-432 it), a bacterial biological response modifier, in patients with gastric cancer. The 10-year survival and disease-free survival were examined and analysis of the factors showing survival benefit was performed. 370 patients who had undergone curative resection of gastric cancer were enrolled in this study and followed up for 10 years postoperatively. Patients were randomized into either an OK-432 it group or a control group. Ten Klinishe Einheit (KE) of OK-432 was endoscopically injected at 1 to 2 weeks before the operation in the OK-432 it group. Both groups received the same adjuvant chemoimmunotherapy consisting of a bolus injection of mitomycin C (0.4 mg kg−1i.v.) and administration of tegafur and OK-432 from postoperative day 14 up to 1 year later. Tegafur (600 mg day−1) was given orally and OK-432 (5 KE/2 weeks) was injected intradermally for a maintenance therapy. The TILs grades in resected tumour specimens and presence of metastasis and metastatic pattern in dissected lymph nodes were examined. Multivariate analysis was performed to determine the efficacy of OK-432 it on prognostic factors. All patients were followed up for 10 years. The overall 5- and 10-year survival rates and disease-free survival rates of the OK-432 it group were not significantly higher than those of the control group. However, OK-432 it significantly increased the 5- and 10-year survival rates of patients with stage IIIA + IIIB, moderate lymph node metastasis (pN2), and positive TILs. OK-432 it was most effective at prolonging the survival of patients who had both positive TILs and lymph node metastasis. The OK-432 it group with positive TILs showed a significant decrease in metastatic lymph node frequency and in the number of lymph node micro- metastatic foci when compared to

Clinical and organizational aspects of the preoperative visit can have a significant impact on patient satisfaction. The authors' previous work demonstrated that communication of information from the clinician to the patient was found to be the most positively rated component, whereas organizational issues, particularly waiting time, were the most negative. This study compares two yearly cycles of patient satisfaction surveys to assess the process and impact of implementation of changes. The authors distributed a one-page questionnaire, consisting of elements evaluating satisfaction with clinical providers and with organizational aspects of the visit, to patients in their preoperative clinic during two different time periods. Fourteen different questions had five Likert scale options ranging from excellent to poor. Changes implemented included clerical, scheduling, and clinical changes. The overall collection rate of completed questionnaires was 79%. The scores for each question in Cycle 2 were higher for all questions, with 3 of 14 reaching statistical significance (P customer service, and implementation of changes in provider roles. These modifications resulted in an improvement in patient satisfaction and a reduction in waiting time with minimal economic impact.

The objective is to evaluate the reliability of patients' recall of preoperative pain and function during the immediate postoperation period after total hip arthroplasty. A prospective cohort of 104 patients completed a survey about their quality of life before operation, and recalled preoperative status at 3 days, 6 weeks, and 12 weeks after operation. Quality of life was measured by the Western Ontario and McMaster University Osteoarthritis Index, the Oxford-12 hip score, and the 12-item Short-Form score. The intraclass correlation coefficient and Spearman correlation coefficient were used to compare preoperative quality of life scores to the scores recalled. The reliability of recall remained high up to 3 months postoperation. Patients are able to accurately recall their preoperative function for up to 3 months after total hip arthroplasty.

In clinical trials, use of patient recall data would be beneficial when the collection of baseline data is impossible, such as in trauma situations. We investigated the ability of older patients to accurately recall their preoperative quality of life, function, and general health status at six weeks following total hip arthroplasty. We randomized consecutive patients who were fifty-five years of age or older into two groups. At each assessment, patients completed self-report questionnaires (at four weeks preoperatively, on the day of surgery, and at six weeks and three months postoperatively for Group 1 and at six weeks and three months postoperatively for Group 2). At six weeks postoperatively, all patients completed the questionnaires on the basis of their recollection of their preoperative health status. We evaluated the validity and reliability of recall ratings, the degree of error in recall ratings, and the effects of the use of recall data on power and sample size requirements. A total of 174 patients (mean age, seventy-one years) who were undergoing either primary or revision total hip arthroplasty were randomized and included in the analysis (118 patients were in Group 1 and fifty-six were in Group 2). Agreement between actual and recalled data was excellent for disease-specific questionnaires (intraclass correlation coefficient, 0.86, 0.87, and 0.88) and moderate for generic health measures (intraclass correlation coefficient, 0.48, 0.58, and 0.60). Increased error associated with recalled ratings compared with actual ratings necessitates minimal increases in sample size or results in small decreases in power. Patients undergoing total hip arthroplasty can accurately recall their preoperative health status at six weeks postoperatively.

Full Text Available Background: Infectious complications of hysterectomy remain common despite the use of antibiotic. The usual existing methods of preoperative antisepsis do not control the vaginal bacteria that are the primary cause of contamination at the surgical site. Our goal was to assess whether febrile morbidity after total abdominal hysterectomy is decreased by the addition of povidone-iodine gel at the vaginal apex after the routine vaginal preparation with povidone-iodine solution.Methods: We carried out a prospective randomized trial on women admitted for elective abdominal hysterectomy. Inclusion criteria included planned abdominal hysterectomy for benign or malignant gynecologic conditions. Exclusion criteria consisted of emergency surgery, current treatment for pelvic infection, and known povidone-iodine allergy. A total of 168 patients were randomized to either the control group or the intervention group, who received 20 cc povidone-iodine gel placed at the vaginal apex immediately before the operation. Both groups received the routine preoperative preparation of antimicrobial prophylaxis, abdominal and vaginal scrubbing with povidone-iodine solution prior to the operation. The primary outcome was post-operative febrile morbidity. Other outcomes included abdominal wound infection, vaginal cuff cellulitis or pelvic abscess. Data was analyzed using Fisher's exact test. p<0.05 was considered statistically significant.Results: The overall rate of febrile morbidity was 20.5%. Febrile morbidity occurred in ten of 80 (12.5% women receiving the povidone-iodine gel preparation and 24 of 86 (27.9% women not receiving the gel (p<0.05. The rate of abdominal wound infection was 18.6% (16 in the control group, and 5% (4 in the gel group (p<0.05. Vaginal cuff cellulitis was seen in three patients from the control group versus one woman from the gel group (p>0.05. Pelvic abscess was diagnosed in one patient from the control group and in no patients from the

To systematically assess the physicians' point of view of multimedia support in preoperative patient education for radical prostatectomy. We evaluated the view of physicians performing multimedia supported preoperative educations within a randomized controlled trial. Therein 8 physicians educated 203 patients for radical prostatectomy. All physicians rated multimedia supported education better than the standard procedure. Main reasons were better comprehensibility, the visual presentation, and greater ease in explaining complex issues. Objective time measurement showed no difference between both educations. The major disadvantage was the impression, that multimedia supported education lasted longer. Moreover, they had the impression that some details could be further improved. Given the choice, every physician would decide for multimedia support. Physicians appreciate multimedia support in preoperative education and contrary to their impression, multimedia support does not prolong patient education. Therefore, patients and physicians likewise profit from multimedia support for education and counseling. The readiness of physicians is a possible obstacle to this improvement, as their view is a key factor for the transition to everyday routine. Therefore, our results could alleviate this possible barrier for establishing multimedia supported education in clinical routine. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

2008-01-01

Detailed preoperative staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require preoperative therapy for tumour regression. This information can be used to instigate neoadjuvant therapy in those patients with poor prognostic features prior to disturbing the tumour bed and potentially disseminating disease. The design of trials incorporating MR assessment of prognostic factors prior to therapy has been found to be of value in assessing treatment modalities and outcomes that are targeted to these preoperative prognostic subgroups and in providing a quantifiable assessment of the efficacy of particular chemoradiation treatment protocols by comparing pre-treatment MR staging with post therapy histology assessment. At present, we are focused on achieving clear surgical margins of excision (CRM) to avoid local recurrence. We recommend that all patients with rectal cancer should undergo pre-operative MRI staging. Of these, about half will have good prognosis features (T1-T3b, N0, EMVI negative, CRM clear) and may safely undergo primary total mesorectal excision. Of the remainder, those with threatened or involved margins will certainly benefit from pre-operative chemoradiotherapy with the aim of downstaging to permit safe surgical excision. In the future, our ability to recognise features predicting distant failure, such as extramural vascular invasion (EMVI) may be used to stratify patients for neo-adjuvant systemic chemotherapy in an effort to prevent distant relapse. The optimal pre-operative treatment regimes for these patients (radiotherapy alone, systemic chemotherapy alone or combination chemo-radiotherapy) is the subject of current and future trials.

2009-01-01

Purpose: To evaluate the toxicity and efficacy of preoperative intensity-modulated radiotherapy (IMRT) combined with temozolomide to improve local tumor control in soft-tissue sarcoma (STS). Patients and Methods: A cohort of 15 consecutive patients with nonmetastasized, primary high-grade or locally recurrent Stage III (n = 14) or IIb (n = 1) STS not amenable to surgical resection without significant organ or extremity function loss was prospectively investigated. Median tumor size was 9.8 cm, and most tumors were non-extremity sarcomas. Patients preoperatively received 50 mg/m 2 of temozolomide during IMRT (50.4 Gy). Resection was intended 6 weeks thereafter. Toxicity was assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0, and response was assessed by Response Evaluation Criteria in Solid Tumors. Results: Of 15 patients, 14 completed preoperative treatment. No Grade 4 toxicities occurred. Nausea and vomiting were the most frequent Grade 3 toxicities. The most frequent toxicities of any grade were dermatologic, gastrointestinal, and hematologic. Response was partial response in 5, stable disease in 7, and progressive disease in 2 patients. Ten patients underwent surgery: 7 were resected with clear margins (R0), and 2 patients had an R1 resection; in 1 patient the tumor was not resectable. Postoperative complications occurred in 4 patients. Five patients did not undergo surgery because of intercurrent metastatic disease, unresectable disease, or refusal. Conclusions: Preoperative chemoradiation with temozolomide and IMRT can be administered safely and with promising efficacy in patients with locally advanced STS.

Full Text Available Background. Identification and management of risk factors for stroke following isolated coronary artery bypass grafting (CABG could potentially lower the risk of such serious morbidity. Methods. We retrieved data for 30-day stroke incidence and perioperative variables for patients undergoing isolated CABG and used multivariate logistic regression to assess the adjusted effect of preoperative hematocrit concentration on stroke incidence. Results. In 2,313 patients (mean age 65.9 years, 73.6% men, 43 (1.9%, 95% CI: 1.4–2.5 developed stroke within 30 days following CABG (74.4% within 6 days. After adjustment for a priori defined potential confounders, each 1% drop in preoperative hematocrit concentration was associated with 1.07 (95% CI: 1.01–1.13 increased odds for stroke (men, OR: 1.08, 95% CI: 1.01–1.16; women, OR: 1.02, 95% CI: 0.91–1.16. The predicted probability of stroke for descending preoperative hematocrit concentration exceeded 2% for values <37% (<37% for men (adjusted OR: 2.39, 95% CI: 1.08–5.26 and <38% for women (adjusted OR: 2.52, 95% CI: 0.53–11.98, with a steeper probability increase noted in men. The association between lower preoperative hematocrit concentration and stroke was evident irrespective of intraoperative transfusion use. Conclusion. Screening and management of patients with low preoperative hematocrit concentration may alter postoperative stroke risk in patients undergoing isolated CABG.

The prognostic role of post-chemoradiotherapy (CRT) carcinoembryonic antigen (CEA) level is not clear. We evaluated the prognostic significance of post-CRT CEA level in patients with rectal cancer after preoperative CRT. We reviewed 659 consecutive patients who underwent preoperative CRT and total mesorectal excision for non-metastatic rectal cancer. Patients were categorized into two groups according to post-CRT serum CEA level: low CEA (level was 1.7 ng/mL (range, 0.1-207.0). A high post-CRT level was significantly associated with ypStage, ypT category, tumor regression grade, and pre-CRT CEA level. The 5-year overall survival rate of the 659 patients was 87.8% with a median follow-up period of 57.0 months (range, 1.4-176.4). When the post-CRT CEA groups were divided into groups according to pre-CRT CEA level, the 5-year overall survival rates were significantly different (P level was an independent prognostic factor for overall survival. Multivariate analysis revealed that operation method, differentiation, perineural invasion, postoperative chemotherapy, tumor regression grade, and post-CRT CEA level were independent prognostic factors for overall survival. The level of serum CEA after preoperative CRT was an independent prognostic factor for overall survival in patients with rectal cancer.

Full Text Available The goal of preoperative pharmacotherapy in patients with breast cancer is to enable breast conserving surgery in stage T3N0-1M0 or radical mastectomy in patients with primary inoperative tumors (T1-4N0-3M0. The choice of optimal treatment should be based not only on risk factors resulting from the stage but also on predicted cancer responsiveness to the treatment. The breast cancer subtypes defined by immunohistochemical profile (expression of ER, PR, HER2 and Ki67 are characterized by different responsiveness to therapy. Complete response confirmed by histopathological evaluation after neoadjuvant chemotherapy is a positive prognostic factor in some breast cancer subtypes. This marker is not of value in postmenopausal patients with ER/PR+ HER2– tumors, who are candidates for neoadjuvant hormone therapy. These patients have a good prognosis if in a histopathological report after surgery there are features such as pT1, pN0, Ki67 < 3%, and ER Allred score ≥ 3. The goal of the paper is to present current knowledge about preoperative pharmacotherapy of breast cancer.

Background Preoperative knee function is associated with successful postoperative outcome after ACL reconstruction (ACLR). However, there are few longer-term studies of patients who underwent progressive preoperative and postoperative rehabilitation compared to usual care Objectives To compare preoperative and 2 year postoperative patient-reported outcomes (PROs) in patients undergoing progressive preoperative and postoperative rehabilitation at a sports medicine clinic compared with usual care Methods We included patients aged 16–40 years undergoing primary unilateral ACLR. The preoperative and 2 year postoperative KOOS of 84 patients undergoing progressive pre- and postoperative rehabilitation at a sports medicine clinic (Norwegian Research Center for Active Rehabilitation [NAR] cohort) were compared with the scores of 2690 patients from the Norwegian Knee Ligament Registry (NKLR). The analyses were adjusted for sex, age, months from injury to surgery, and cartilage/meniscus injury at ACLR. Results The NAR cohort had significantly better preoperative KOOS in all subscales, with clinically relevant differences (>10 points) observed in KOOS Pain, ADL, Sports and Quality of Life. At 2 years, the NAR cohort still had significantly better KOOS with clinically relevant differences in KOOS Symptoms, Sports and Quality of Life. At 2 years, 85.7–94.0 % of the patients in the NAR cohort scored within the normative range of the different KOOS subscales, compared to 51.4–75.8 % of the patients in the NKLR cohort. Conclusion Patients in a prospective cohort who underwent progressive pre- and postoperative rehabilitation at a sports medicine clinic showed superior patient-reported outcomes both preoperatively and 2 year postoperatively compared to patients in the Norwegian Knee Ligament Registry who received usual care.

Full Text Available Context: Patients are fasting for inappropriately long duration preoperatively despite the American Society of Anesthesiologists (ASA recommendations for liberal fasting guidelines. There is paucity of data on preoperative fasting duration in the day care patient population from India; hence, we studied the preoperative fasting status in the day care patient population. Aims: This study aims to study the preoperative fasting duration for solids and clear fluids and to compare the fasting times in the patients posted for the morning slot and the afternoon slot. Settings and Design: This was a prospective, observational, cross-sectional study at a tertiary care, teaching institute. Subjects and Methods: All Consenting adults, ASA grade 1 or 2, of either gender, presenting for day care surgery were included in the study. Data collected included the demographic profile, duration of fasting for solids, and clear fluids. The patients rated their hunger and thirst on a ten point numeric rating scale. We compared the fasting durations for solids and clear fluids in the patients presenting for the morning slot and afternoon slot for surgery. Statistical Analysis Used: T-test was used for analysis of continuous data with normal distribution and Mann–Whitney U-test for data with nonnormal distribution. Chi-square test was performed for categorical variables. Differences were considered significant at P < 0.05. Results: The mean duration of preoperative fasting for solids was 12.58 ± 2.70 h and for clear fluids was 9.02 ± 3.73 h. The mean fasting duration for solids in the patients presenting for the afternoon slot was significantly longer (P < 0.0001 than those presenting for the morning slot. The mean preoperative fasting duration for clear fluids was comparable among these patient groups (P = 0.0741. Conclusions: Patients are following inappropriately prolonged fasting routines, and there is a need to enforce liberal preoperative fasting guidelines

Full Text Available BACKGROUND AND OBJECTIVE: To investigate the influence of intraoperative and preoperative positive pressure in the time of extubation in patients undergoing bariatric surgery. METHOD: Randomized clinical trial, in which 40 individuals with a body mass index between 40 and 55 kg/m2, age between 25 and 55 years, nonsmokers, underwent bariatric surgery type Roux-en-Y gastric bypass by laparotomy and with normal preoperative pulmonary function were randomized into the following groups: G-pre (n = 10: individuals who received treatment with noninvasive positive pressure before surgery for 1 h; G-intra (n = 10: individuals who received positive end-expiratory pressure of 10 cm H2O throughout the surgical procedure; and G-control (n = 20: not received any preoperative or intraoperative intervention. Following were recorded: time between induction of anesthesia and extubation, between the end of anesthesia and extubation, duration of mechanical ventilation, and time between extubation and discharge from the post-anesthetic recovery. RESULTS: There was no statistical difference between groups. However, when applied to the Cohen coefficient, the use of positive end-expiratory pressure of 10 cm H2O during surgery showed a large effect on the time between the end of anesthesia and extubation. About this same time, the treatment performed preoperatively showed moderate effect. CONCLUSION: The use of positive end-expiratory pressure of 10 cm H2O in the intraoperative and positive pressure preoperatively, influenced the time of extubation of patients undergoing bariatric surgery.

The transmembrane glycoprotein CA 15-3 is the most widely used serum tumor marker in breast cancer. At present the main uses of CA 15-3 are in pre-clinically detecting recurrent breast cancer and monitoring the treatment of patients with advanced breast cancer. The aim of this study was to define the role of preoperative concentrations of serum CA 15-3a sp rognostic factor and to determine its sensitivity. Serum and plasma samples from breast cancer patients and normal individuals under fasting condition were used to estimate CAlS-3 and lipid profile. The lipid profile was done in order to assess the impact of plasma lipid on the progression of breast cancer. The serum concentration of the tumor marker CAlS-3 in preoperative breast cancer patients was found to be significantly higher (p<0.001) as compared to the normal individuals. The plasma cholesterol (TC), triglyceride (TRG) and total lipid (TL) levels in breast cancer patients were found to be significantly higher (p< O.OI) for TC, TRG and TL as compared to the normal individuals. Moreover, plasma LDL-C levels in breast cancer patients were found to be significantly higher (p< O.OI) compared to the normal individuals. (author)

Impaired postural balance due to somatosensory data loss with mechanical instability has been shown in patients with ACL deficiency. To assess postural balance in patients with ACL insufficiency prior to surgery and following reconstruction with serial evaluations. Thirty patients (mean age of 27.7 ± 6.7 years) who underwent arthroscopic reconstruction of ACL with bone-patellar tendon-bone autograft were examined for clinical and functional variables at preoperative day and postoperative 12th week. Posturographic analysis were performed by using Tetrax Interactive Balance System (Sunlight Medical Ltd, Israel) at preoperative day, at 4th, 8th, and 12th weeks following reconstruction. Data computed by posturographic software by the considerations of the oscillation velocities of body sways is fall risk as a numeric value (0-100, lower values indicate better condition). All of the patients (mean age of 27.7 ± 6.7 years) had significant improvements for clinical, functional evaluations and fall risk (pfall risk was within high-risk category (59.9 ± 22.8) preoperatively. The highest fall risk was detected at postoperative 4th week. Patients had high fall risk at 8th week similar to preoperative value. Mean fall risk decreased to low level risk at 12th week. Preoperative symptom duration had relationships with preoperative fall risk and postoperative improvement of fall risk (p= 0.001, r= -0.632, p= 0.001, r= -0.870, respectively). The improvement of fall risk was higher in patients with symptoms shorter than 6 months (p= 0.001). According to these results, mean fall risk of patients with ACL insufficiency was within high risk category preoperatively, and fall risk improves after surgical reconstruction, but as the duration of complaints lengthens especially longer than 6 months, the improvement of fall risk decreases following reconstruction.

To determine the effect of dextrose containing solution (5% dextrose in 0.45% NaCl) compared to non-dextrose containing solution (lactated Ringer's solution) on plasma glucose level in elective surgical patients. A prospective randomized double-blind control trial was conducted on 60 patients aged 18-60, with ASA physical status I to II, who were scheduled for elective surgery at Maharaj Nakorn Chiang Mai Hospital, Thailand between October; 2007 and September; 2008. The patients received either lactated Ringer's solution (Group L), or 5% dextrose in 0.45% NaCl (Group D) in the morning of the operation day. Blood glucose levels were determined before intravenous fluid administration (T0), at the beginning (T1), after the 1st hr (T2), and at the end of surgery (T3). Mean duration of preoperative fast was almost 11 hrs in both groups; however, none of the patients had preoperative hypoglycemia. The blood sugar levels were significantly higher in the patients receiving 5% dextrose solution compared to the patients receiving lactated Ringer's solution at the beginning, after the 1st hr and at the end of surgery (p-value = 0.06, 0.018 and 0.036 respectively). There were some patients having hyperglycemia after receiving 5% dextrose in 0.45% NaCl during surgery. However, none of the average plasma glucose values in either group was considered as hyperglycemia. Though they fasted many hours before surgery, no patients were found to have hypoglycemia. The large volume of lactate Ringer's solution had minimal effect on the blood sugar levels compared to the levels in 5% dextrose in 0.45% NaCl group. Therefore, lactate Ringer's solution is probably the alternative choice of intravenous fluid for perioperative maintenance and can be used as replacement in healthy patients undergoing elective surgery.

Patients and their families are understandably anxious about the risk of complications and unfamiliar experiences following cardiac surgery. Providing information about postoperative care in the intensive care unit (ICU) to patients and families may lead to lower anxiety levels, and increased satisfaction with healthcare. The objectives of this study are to evaluate the effectiveness of preoperative patient education provided for patients undergoing elective cardiac surgery. 100 patients undergoing elective coronary artery bypass graft, with or without valve replacement surgery, will be recruited into a 2-group, parallel, superiority, double-blinded randomised controlled trial. Participants will be randomised to either preoperative patient education comprising of a video and ICU tour with standard care (intervention) or standard education (control). The primary outcome measures are the satisfaction levels of patients and family members with ICU care and decision-making in the ICU. The secondary outcome measures are patient anxiety and depression levels before and after surgery. Ethical approval has been obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (reference number CREC 2015.308). The findings will be presented at conferences and published in peer-reviewed journals. Study participants will receive a 1-page plain language summary of results. ChiCTR-IOR-15006971.

We evaluated whether pre-emptive analgesia with a pre-operative ultrasound-guided infraclavicular brachial plexus block resulted in better postoperative analgesia than an identical block performed postoperatively. Fifty-two patients undergoing fixation of a fractured radius were included. All patients received general anaesthesia with remifentanil and propofol. Patients were randomly allocated into two groups: a pre-operative block or a postoperative block with 0.5 ml.kg -1 ropivacaine 0.75%. After surgery, all patients received regular paracetamol plus opioids for breakthrough pain. Mean (SD) time to first rescue analgesic after emergence from general anaesthesia was 544 (217) min in the pre-operative block group compared with 343 (316) min in the postoperative block group (p = 0.015). Postoperative pain scores were higher and more patients required rescue analgesia during the first 4 h after surgery in the postoperative block group. There were no significant differences in plasma stress mediators between the groups. Analgesic consumption was lower at day seven in the pre-operative block group. Pain was described as very strong at block resolution in 27 (63%) patients and 26 (76%) had episodes of mild pain after 6 months. We conclude that a pre-operative ultrasound-guided infraclavicular brachial plexus block provides longer and better analgesia in the acute postoperative period compared with an identical postoperative block in patients undergoing surgery for fractured radius. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

To determine the pathologic effectiveness of preoperative chemoradiotherapy (CRT) in patients with advanced rectal carcinoma, we reviewed clinical records of 76 patients who received preoperative pelvic radiation +/- chemotherapy. Since 2 patients refused operation and 2 died before surgery, 72 patients underwent operation with a mean delay of 19.9 days after completion of irradiation. Pathologic tumor regression grade (Grade 0-3) was determined by the amount of viable tumor versus necrosis and fibrosis. Grade 0, 1a, 1b, 2, and 3 (pCR) were observed in 0%, 25.0%, 38.9%, 27.8% and 2.8% of patients, respectively. The pathologic response (PR) rate was 75.0% when PR was defined as greater than grade 1b (tumor regression more than 1/3). Downstaging was observed in 35.8% of patients, in which 5-year overall survival was significantly better than in patients without downstaging (90.0% vs. 50.1%, p<0.05). No correlation could be observed between PR and downstaging. CRT is a useful tool with a high PR rate in patients with advanced rectal cancer. More accurate and careful clinical staging is important to select adequate candidates for CRT. Multi-institutional clinical trials as well as standardizing the surgical procedure including lymph node (LN) dissection are required to validate the advantages of CRT for Japanese patients.

Background and purpose: preoperative radiochemotherapy (RCT) followed by curative surgery is a well-accepted therapeutic option in the treatment of advanced rectal cancer. Usually, the anal sphincter is located in the irradiation area of a preoperative RCT regime. The aim of this study is to evaluate the influence of preoperative RCT on anal sphincter function. Patients and methods: between 1994 and 2000, 102 patients with rectal cancer stage uT3/uT4 were analyzed. All patients underwent radiotherapy with 45 Gy (5 x 1.8 Gy) including two cycles of 5-fluorouracil (5-FU)/leucovorin (folinic acid) chemotherapy. 46 patients were treated additionally with up to five sessions of locoregional hyperthermia. The sphincter function was analyzed by perfusion manometry before preoperative therapy and 4 weeks after pretreatment had been finished. For statistics, the Wilcoxon signed rank test and mann-whitney U-test were used (SPSS 9.0 for Windows trademark). Results: the mean value of all 102 patients showed a significant reduction of the mean maximum resting pressure from 97 to 89 mmHg (p = 0.02). For the mean maximal squeeze pressure no significant difference could be shown (178 vs. 176 mmHg). For patients with distal (≤ 7.5 cm from anal verge) tumors the difference was highly significant (92 vs. 79 mmHg). Locoregional hyperthermia had no additional influence on sphincter function. Conclusion: preoperative RCT impairs sphincter function especially in patients with distal tumors. In addition, RCT could have a negative influence on the continence of patients who received sphincter-preserving surgery. (orig.) [de

Full Text Available BACKGROUND: An elevated preoperative C-reactive protein/albumin (CRP/Alb ratio has been reported to be associated with a poor prognosis for hepatocellular carcinoma. The aim of the present study was to investigate the prognostic value of the preoperative CRP/Alb ratio and compare it with other systemic inflammatory response markers in patients with gastric cancer (GC. METHODS: A retrospective study was performed in 455 patients with GC undergoing curative resection. We investigated the correlations between the preoperative CRP/Alb ratio and overall survival (OS. Kaplan-Meier and Cox regression models were used to assess independent prognostic factors. The area under the curve was used to compare the prognostic value of different markers. RESULTS: On multivariate analysis, the CRP/Alb ratio were independently associated with OS in patients with GC (hazard ratio: 1.626; 95% confidence interval: 1.191-2.219; P = .002, along with age (P = .003, preoperative body weight loss (P = .001, tumor location (P = .008, metastatic lymph node ratio (P < .001, and seventh tumor-nodes-metastasis stage (American Joint Committee on Cancer (P = .007. However, several other systemic inflammation–based prognostic scores (neutrophil lymphocyte ratio, platelet lymphocyte ratio and systemic immune-inflammation index, Glasgow Prognostic Score, modified Glasgow prognostic score, and high-sensitivity modified Glasgow prognostic score were not. In addition, the CRP/Alb ratio had a higher area under the curve value (0.625 compared with several other systemic inflammation–based prognostic scores (P < .001. CONCLUSION: The preoperative CRP/Alb ratio, a system inflammation-based prognostic score, is a superior predictor of OS in patients undergoing curative resection for GC and may help to identify the high-risk patients for treatment decisions.

Preoperative evaluation of patients with suspected or confirmed lung cancer consists of clinical and radiological staging. Malignant pleural effusion is a poor prognosticator in non-small-cell lung cancer. Pleural ultrasound (PU) allows for the assessment of pleural effusion, providing real-time guidance for its aspiration and cytological analysis. Pleural Ultrasonography in Lung Cancer (PULC) as an adjunct to physical examination has the potential to improve preoperative staging of non-small-cell lung cancer during first surgical encounter by allowing the evaluation of previously unassessed pleural effusion. This study consisted of a prospective trial of surgeon-performed PU in the preoperative evaluation of lung cancer patients. All patients evaluated in the thoracic surgery clinic with the new or presumed diagnosis of lung cancer were eligible. A portable ultrasound machine was used to evaluate pleural fluid in the bilateral costophrenic sulci with pleural fluid aspiration for cytological analysis. Forty-five patients were prospectively enrolled over a 3-month period. Thirteen patients had ultrasound evidence of a pleural effusion, of which 3 were significant enough for aspiration. Cytological analysis of these effusions yielded malignant cells in 1 patient. Positive PULC evaluation led to a change in clinical staging (M0 to M1a) in 10 patients and a change in pathological staging (pleural fluid cytology positive) in 1 patient. The time required for PULC examination was 15 ± 7 min. There were no complications related to the procedures. Preoperative pleural ultrasonography is a rapid and effective way to improve precision of staging in patients with lung cancer. More precise staging may allow for more appropriate testing, patient prognostication and operative planning.

The aim of this study was to determine the kind of information patients need preoperatively about postoperative pain (POP) and whether this is affected by previous surgery experience. A descriptive study design using preoperative questionnaires. Questionnaires with fixed questions related to POP and its management were distributed preoperatively to consenting, consecutive surgical patients. Patients were divided into two groups: patients with previous surgery experience (group A) and patients without previous surgery experience (group B). Of the patients who participated in the study, 94.2% wanted information about POP and 77.8% of them believe that they will feel calmer if they get the information they need. The patients' biggest concern relates to pain management issues after discharge. Next, in order of preference is information about the analgesics that they need to take. The patients want to be informed primarily with a personal interview (59.4%). Previous surgery experience has no effect on patients' needs for information. Most of the patients want to be informed about the management of the POP after being discharged. It is remarkable that patients who had previous surgery experience need the same information with those who had no previous surgery. Copyright © 2016 American Society of PeriAnesthesia Nurses.

The aim of our study was to assess the predictive value of preoperative inflammatory markers, such as the neutrophil–lymphocyte ratio (NLR, platelet–lymphocyte ratio, red cell distribution width (RDW, and mean platelet volume, for survival in breast cancer patients. In total, 608 breast cancer patients operated on between January 2009 and December 2011 were included in this observational study. The association between preoperative inflammatory markers and survival outcomes was analyzed. Patients with high NLR (>2.57 or high RDW (>13.45% showed a significantly lower overall survival rate than those with lower NLR (≤2.57 or lower RDW (≤13.45%. NLR and RDW, along with node stage and molecular subtypes, were independent prognostic factors. There was a significant survival difference according to NLR in the luminal A and triple-negative subtypes (93.3% versus 99.3%, P=0.001; 68.8% versus 95.1%, P=0.000, respectively. The triple-negative subtype was the only subtype in which higher RDW patients showed significantly poor prognosis (81.3% versus 95.5%, P=0.025. Pre-operation NLR and RDW is a convenient, easily measured prognostic indicator for patients with breast cancer, especially in patients with the triple-negative subtype.

Preoperative stoma site marking and counseling aim to improve patients' rehabilitation and adaptation to a new medical condition. Objective studies are needed to provide evidence of the impact of care by stoma therapists. Key quality indicators include patients' quality of life, independence, and complication rates as affected by the variable modes of stoma site marking and planning. The aim of this study was to evaluate the impact of preoperative stoma site marking on patients' quality of life, independence, and complication rates. : A validated stoma quality-of-life questionnaire was used as the main assessment tool. Complications were noted on regular postoperative visits. This is a single-center, clinical study. The study was conducted at the Rambam Health Care Campus in Haifa, Israel. Rambam Health Care Campus is a tertiary university hospital. All patients who underwent an elective stoma creation between 2006 and 2008 were included. Evaluated parameters included demographics, stoma type, marking status, complication rates, quality of life, and independence parameters. : One hundred five patients (60 men and 45 women) were included, of whom 52 (49.5%) were preoperatively marked and 53 (50.5%) were not marked. Sixty stomas (57%) were permanent, and 45 (43%) stomas were temporary. The quality of life of patients whose stoma sites were preoperatively marked was significantly better than that of the unmarked patients (p stoma type. Preoperative stoma site marking is crucial for improving patients' postoperative quality of life, promoting their independence, and reducing the rates of postoperative complications. The role of the enterostomal therapist is very important in the ostomates' pre- and postoperative care.

The value of a preoperative chest radiograph is twofold. The examination may reveal unsuspected pathology that would alter the approach to surgery of anesthesia. Secondly, it provides a baseline or reference from which to evaluate subsequent post-operative films. The percentage of detection of unsuspected pathology on preoperative chest radiographs has been shown to be exceedingly small in certain patient populations. The authors do not recommend routine use of preoperative chest radiographs in children or in adults under the age of 40 who do not smoke, unless (1) the surgical disease has chest manifestations; (2) there is historic or clinical evidence of a coexisting disease with chest involvement; or (3) there is a likelihood that post-operative management will require follow-up films

To visualize the posterior portion of eye globe in dense cataract patients with B scan ultrasound, and to find out any posterior segment lesion in such pre-operative cases. We performed diagnostic B-scan ultrasound on 750 cataract patients before surgery. This was a prospective diagnostic study which was conducted in the Department of Opthalmology, Liaquat University Eye Hospital, Hyderabad Sind, Pakistan from January 2007 to July 2007. Detailed history and some basic eye examination techniques, like slit lamp and tonometry were done in two groups of patients, traumatic (71) and non traumatic(679). Patients in the age range of 1 to 79 years of both sexes were included. Patients having already posterior segment lesions and those who had previous history of ocular surgery were excluded from the study. An ultrasound machine Nidek Echo Scan Model US-3300 with a probe of direct contact was used. Out of 750 patients, 90 patients had posterior segment lesions. Among traumatic group of 71 patients, 39 (55%) had positive posterior segment lesions, while in the non traumatic group of 679 patients, only 51 (7%) cases had positive posterior segment lesions. Out of the 90 positive cases, 25 (3%) had retinal detachment, 14 (2%) had posterior vitreous detachment, 24 (3%) had vitreous hemorrhage, 12 (2%) were asteroid hyolosis, while posterior staphyloma and intra-ocular foreign body were found with the frequency of 9 (1.2%) and 6 (1%), respectively. We concluded that two dimensional B-scan ultrasound can be one of the diagnostic tool for the detection of hidden posterior segment lesions and can be performed routinely in pre-operative cataract patients, as this would help in surgical planning. In cases, where a two dimensional B-scan is not sufficient or helpful. a three dimensional ultrasound would be justified.

The results of a study are presented of the basal level of insulin and glucagon in gastric cancer patients, Stages 2-4, and in practically healthy subjects. The examination of the basal level of these hormones in the patients was repeated following preoperative irradiation and radical surgical treatment of the stomach. The function of the ..beta..-cells of the pancreatic insular apparatus was studied in gastric cancer patients using the glucose tolerance test. The basal level of insulin and glucagon before theatment in the entire group of patients did not significantly differ from that in the group of healthy persons. Preoperative irradiation of patients caused changes in the concentration of insulin and glucagon in the blood; 2 types of reactions were revealed: in patients with an initially low level of insulin and a high level of glucagon irradiation caused an increase in the content of blood insulin; in patients with the normal content of these hormones irradiation resulted in a considerable decrease of the insulin content.

Young children who experience high levels of preoperative anxiety often exhibit distress behaviors, experience more surgical complications, and are at a higher risk for developing a variety of negative postoperative consequences. A significant factor in pediatric preoperative anxiety is the level of anxiety present in their caregivers. Active and passive music therapy interventions addressing anxiety prior to invasive procedures have been met with success. The purpose of this study was to investigate the comparative effectiveness of two distraction-based music therapy interventions on reducing preoperative anxiety in young pediatric surgical patients and their caregivers. A total of 40 pediatric patient and caregiver dyads undergoing ambulatory surgery were included in this study. Pediatric preoperative anxiety was measured pre- and post-intervention using the modified Yale Pediatric Anxiety Scale, while caregiver anxiety was measured through self-report using the short-form Strait-Trait Anxiety Inventory-Y6. Participants were randomized to either an active or passive intervention group for a preoperative music therapy session. Results indicated a significant reduction in preoperative anxiety for both patients and their caregivers regardless of intervention type. Neither active nor passive music therapy interventions were significantly more effective than the other. For future studies, the researchers recommend an increased sample size, controlling for various factors such as sedative premedication use, and testing interventions with patients in various stages of development. © the American Music Therapy Association 2017.

To investigate whether malnutrition is associated with poor prognosis of patients who undergo salvage esophagectomy. We examined the association between the preoperative prognostic nutritional index (PNI) and prognosis of patients who undergo salvage esophagectomy. We conducted a single-center retrospective study and reviewed hospital patient records for tumor characteristics and patient outcomes. Univariate and multivariate survival analyses were carried out using the Cox proportional hazards regression model. Thirty-two patients with esophageal squamous cell carcinoma (ESCC) who underwent salvage esophagectomy between 1998 and 2015 at our Institute were included in this study. Univariate analysis revealed that clinical response (p=0.045), preoperative PNI (pnutritional status is associated with the prognosis of patients undergoing salvage esophagectomy.

Provision of preoperative information can alleviate patients' anxiety. However, the ideal method of delivering this information is unknown. Video information has been shown to reduce patients' anxiety, although little is known regarding the effect of preoperative multimedia information on anxiety in patients undergoing regional anaesthesia. We randomized 110 patients undergoing upper or lower limb surgery under regional anaesthesia into the study and control groups. The study group watched a short film (created by the authors) depicting the patient's in-hospital journey including either a spinal anaesthetic or a brachial plexus block. Patients' anxiety was assessed before and after the film and 1 h before and within 8 h after their operation, using the Spielberger state trait anxiety inventory and a visual analogue scale. There was no difference in state and trait anxiety between the two groups at enrollment. Women had higher baseline state and trait anxiety than men (P=0.02). Patients in the control group experienced an increase in state anxiety immediately before surgery (P<0.001), and patients in the film group were less anxious before operation than those in the control group (P=0.04). After operation, there was a decrease in state anxiety from baseline in both groups, but patients in the film group were less anxious than the control group (P=0.005). Preoperative multimedia information reduces the anxiety of patients undergoing surgery under regional anaesthesia. This type of information is easily delivered and can benefit many patients.

An immune-enhancing diet has been used to alter eicosanoid synthesis, cytokine production, and immune function in an attempt to limit the undesired immune reactions after injury from surgery. This prospective randomized study was designed to investigate the effect of preoperative immunonutrition on operative complications, and the participation of prostaglandin E2 (PGE2) on T-cell differentiation in patients undergoing a severely stressful surgery. The enrolled patients who were scheduled to undergo pancreatoduodenectomy were randomized into two groups. Patients in the immunonutrition group (n = 25) received oral supplementation containing arginine, ω-3 fatty acids, and RNA for 5 days before the procedure in addition to a 50% reduction in the amount of regular food. Patients in the control group (n = 25) received no artificial nutrition and were allowed to consume regular food before surgery. All patients received early postoperative enteral infusion of a standard formula intended to provide 25 kcal/kg/day. The primary endpoint was the rate of infectious complications; the secondary endpoint was immune responses. This study is registered with ClinicalTrials.gov (NCT01256034). Infectious complication rate and severity of complications (Clavien-Dindo classification) were lesser in the immunonutrition group than in the control group. mRNA expression levels of T-bet were greater in the immunonutrition group than in the control group (P production and T-cell differentiation and may protect against the aggravation of operative complications in patients undergoing pancreatoduodenectomy.

This study was designed to elucidate the significance of preoperative computed tomography during arterial portography (CTAP) in surgical treatment of hepatocellular carcinoma (HCC). Eighteen patients with HCC whose minute lesions had been pointed out by CTAP preoperatively (CTAP positive group) were compared with another eight patients with HCC having postoperative recurrence in a region at where no tumors had been detected by preoperative CTAP (CTAP negative group) for preoperative location of tumor and postoperative pattern of recurrence. In the CTAP positive group, 11 patients had recurrence and the remaining seven patients had not. Disease-free periods up to recurrences were 8.7 months in an average in the 11 CTAP positive patients and 16.6 months in the CTAP-negative group, showing a significantly shorter interval in the CTAP positive patients. In recurred cases from the CTAP positive group, tumors identified by imaging procedures other than CTAP were solitary in four and multiple in seven cases, while all solitary in non-recurred cases. In the recurred CTAP positive cases, actual recurrence occurred in the same segment where a tumor had been pointed out by CTAP alone in five out of six cases of solitary recurrence; or involved the same segment where CTAP detected tumor (s) in four out of five cases of multiple recurrence. It is indicated that the possibility of postoperative recurrence of HCC is high in cases having minute lesions visualized by CTAP alone in addition to multiple lesions visualized by imaging procedures other than CTAP. We think that periodical imaging methods including CTAP are required for HCC patients. (author)

We reviewed the clinical records of 13 patients who received preoperative chemoradiotherapy (CRT) to evaluate the clinical effectiveness of CRT for T4b rectal cancer. Preoperative radiotherapy consisted of 40-50 Gy delivered in fractions of 1.8-2.0 Gy per day, 5 days per week. Treatment with intravenous 5-fluorouracil, oral tegafur-uracil (UFT-E) with l-leucovorin, oral S-1, or intravenous irinotecan (CPT-11) with oral S-1 was administered during radiotherapy. At 63 days after CRT, 1 patient died because of pelvic abscess. Complete response (CR) or partial response (PR) was observed in 7 patients, 1 month after CRT. Curative surgery was performed in 9 patients. Among 10 patients who underwent surgery 70 days after CRT, 5 who showed PR 1 month after CRT underwent curative surgery; both urinary and anal function were preserved in 4 of these patients. Histological invasion to the adjacent organs was not observed in 6 patients, and 1 patient achieved histological CR. Of the 9 patients who underwent curative surgery, recurrence was observed in 2; however, the other patients survived without recurrence. Preoperative CRT was considered to be effective in improving the resection rate and prognosis in patients with T4b rectal cancer. However, careful attention should be paid to the severe toxicities associated with CRT, such as pelvic abscess. (author)

2017-01-01

Full Text Available Background/Aims: It is well established that obesity is a strongly associated risk factor for post-operative deep vein thrombosis (DVT. Physical effects and pro-thrombotic, pro-inflammatory and hypofibrinolytic effects of severe obesity may predispose to idiopathic DVT (pre-operatively because of which bariatric patients are routinely screened before surgery. The aim of this study was to audit the use of routine screening venous duplex ultrasound in morbidly obese patients before undergoing bariatric surgery. Methods: We retrospectively reviewed 180 patients who underwent bariatric surgery from August 2013 to August 2014 who had undergone pre-operative screening bilateral lower-extremity venous duplex ultrasound for DVT. Data were collected on patient's demographics, history of venous thromboembolism, prior surgeries and duplex ultrasound details of the status of the deep veins and superficial veins of the lower limbs. Results: No patients had symptoms or signs of DVT pre-operatively. No patient gave history of DVT. No patient was found to have iliac, femoral or popliteal vein thrombosis. Superficial venous disease was found in 17 (8%. One patient had a right lower limb venous ulcer. Conclusion: Thromboembolic problems in the morbidly obese before bariatric surgery are infrequent, and screening venous duplex ultrasound can be done in high-risk patients only.

To prevent postoperative local recurrence of rectal cancer, we treated patients using preoperative hyperthermia (5-6 times), irradiation (total 30 Gy) and 5-fluorouracil suppository (2,000-2,500 mg). The subjects were 31 patients given combined treatments and 28 patients given surgery alone. The results were as follows: Histologically, therapeutic effects were recognized in 80.6% of patients receiving combined treatments. The mean distance from the adventitia to the site of cancer infiltration was 6.54 mm in the combined treatments group and 3.35 mm in the surgery alone group. The difference between the two was significant (p<0.05). The rate of local recurrence in the combined treatments group was less than that in the surgery alone group. No systemic side effects nor severe complications were observed during hospitalization in the combined treatments group. The survival rate of the combined treatments group was higher than that of the surgery alone group. It was considered that combined preoperative treatments for rectal cancer were beneficial to survival and local control. (author)

Preoperative transfusion versus no preoperative transfusion Two trials (434 participants) compared a preoperative transfusion plus standard care to a group receiving standard care. Overall, the quality of the evidence was low to very low across different outcomes according to GRADE methodology. This was due to the trials being at high risk of bias due to lack of blinding, and outcome estimates being imprecise. One trial was stopped early because more people in the no transfusion arm developed an acute chest syndrome. There was no difference in all-cause mortality between people receiving preoperative transfusions and those receiving no preoperative transfusions (two trials, 434 participants, no deaths occurred). There was significant heterogeneity between the two trials in the number of people developing an acute chest syndrome, a meta-analysis was therefore not performed. One trial showed a reduced number of people developing acute chest syndrome between people receiving preoperative transfusions and those receiving no preoperative transfusions, risk ratio 0.11 (95% confidence interval 0.01 to 0.80) (65 participants), whereas the other trial did not, risk ratio 4.81 (95% confidence interval 0.23 to 99.61) (369 participants). There were no differences between the preoperative transfusion groups and the groups without preoperative transfusion in the number of people developing: a vaso-occlusive crisis, Peto odds ratio 1.91 (95% confidence interval 0.61 to 6.04) (two trials, 434 participants, very low quality evidence).a serious infection, Peto odds ratio 1.29 (95% confidence interval 0.29 to 5.71) (two trials, 434 participants, very low quality evidence);any perioperative complications, risk ratio 0.24 (95% confidence interval 0.03 to 2.05) (one

Gastric absorption of oral paracetamol (acetaminophen) may be unreliable perioperatively in the starved and stressed patient. We compared plasma concentrations of parenteral paracetamol given preoperatively and oral paracetamol when given as premedication. Patients scheduled for elective ear; nose and throat surgery or orthopaedic surgery were randomised to receive either oral or intravenous paracetamol as preoperative medication. The oral dose was given 30 minutes before induction of anaesthesia and the intravenous dose given pre-induction. All patients were given a standardised anaesthetic by the same specialist anaesthetist who took blood for paracetamol concentrations 30 minutes after the first dose and then at 30 minute intervals for 240 minutes. Therapeutic concentrations of paracetamol were reached in 96% of patients who had received the drug parenterally, and 67% of patients who had received it orally. Maximum median plasma concentrations were 19 mg.l(-1) (interquartile range 15 to 23 mg.l(-1)) and 13 mg.l(-1) (interquartile range 0 to 18 mg.l(-1)) for the intravenous and oral group respectively. The difference between intravenous and oral groups was less marked after 150 minutes but the intravenous preparation gave higher plasma concentrations throughout the study period. It can be concluded that paracetamol gives more reliable therapeutic plasma concentrations when given intravenously.

To compare measurements of motor evoked potential latency stimulated either magnetically (mMEP) or electrically (eMEP) and central motor conduction time (CMCT) made pre-operatively in conscious patients using transcranial and intra-operatively using electrical cortical stimulation before and after successful instrumentation for the treatment of adolescent idiopathic scoliosis. A group initially of 51 patients with adolescent idiopathic scoliosis aged 12-19 years was evaluated pre-operatively in the outpatients' department with transcranial magnetic stimulation. The neurophysiological data were then compared statistically with intra-operative responses elicited by transcranial electrical stimulation both before and after successful surgical intervention. MEPs were measured as the cortically evoked compound action potentials of Abductor hallucis. Minimum F-waves were measured using conventional nerve conduction methods and the lower motor neuron conduction time was calculated and this was subtracted from MEP latency to give CMCT. Pre-operative testing was well tolerated in our paediatric/adolescent patients. No neurological injury occurred in any patient in this series. There was no significant difference in the values of mMEP and eMEP latencies seen pre-operatively in conscious patients and intra-operatively in patients under anaesthetic. The calculated quantities mCMCT and eCMCT showed the same statistical correlations as the quantities mMEP and eMEP latency. The congruency of mMEP and eMEP and of mCMCT and eCMCT suggests that these measurements may be used comparatively and semi-quantitatively for the comparison of pre-, intra-, and post-operative spinal cord function in spinal deformity surgery.

The last few years have witnessed a significant increase in the preoperative use of Magnetic Resonance Imaging (MRI) for staging purposes in breast cancer (BC) patients. Many studies have confirmed the improvement that MRI can provide in terms of diagnostic assessment, especially with regard to additional disease foci. In the present study, we address the advantages and disadvantages of MRI in the preoperative setting for BC patients. There were 1513 consecutive breast MRI studies performed in patients with either primary or recurrent BC, who were scheduled for surgery. Beyond the primary lesion, 10.4% of our cases had additional disease at the final histological assessment. MRI overall sensitivity, when considering tumour size and additional foci together, was 74.3%, and 80.3% when considering additional foci exclusively. MRI specificity for additional disease was 95.3%, positive predictive value was 77.4%, and negative predictive value was 94.6%. Nevertheless, 5% of cases had additional tumours that were missed by MRI or, conversely, had additional foci on MRI that were not confirmed by histology. Age (p=0.020) and lobular carcinomas (p=0.030) showed significance in the multivariate analysis by logistic regression, using the presence of additional foci diagnosed by MRI as a dependent variable. Preoperative MRI seems to have a role in preoperative tumour staging for breast cancer patients, as it discloses additional disease foci in some patients, including contralateral involvement. However, given the lack of absolute accuracy, core-needle biopsy cannot be neglected in the diagnosis of such additional malignant foci, which could result in a change in surgical treatment.

Preoperative localisation of tumour is an essential requirement in laparoscopic colorectal surgery. Since the introduction of laparoscopic colorectal resections in NGH in February 2010, the difficulties of tumour localisation at the time of surgery without tattoo have been highlighted. Furthermore, endoscopic documentation of site of tattoo with respect to the tumour can be inconsistent and at times misleading or difficult to interpret. Tattooing guidelines should be simple to follow and consistent for all lesions irrespective of the location of the tumour. The recommendations were to place at least three spots of tattoo one mucosal fold distal to the lesion and clearly document site of tattoo with respect to tumour in the endoscopy report. We identified 100 patients undergoing elective laparoscopic colorectal cancer resections over a two-year period. Data were collected regarding presence of tattoo preoperatively as documented in the colonoscopy report and subsequently the visibility of the tattoo at time of laparoscopy and its accuracy in relation to the tumour. Abdominoperineal resections and emergency colorectal operations were excluded. Only 59% of the patients had a visible and accurate tattoo. In 17% of the patients, the tattoo was not visible at all, although it was documented in the endoscopy report that it had been administered. In 4% of patients, it was visible but inaccurately placed. In 20% of the patients, there were no tattoos at all, necessitating on table endoscopy and intraoperative specimen analysis to confirm that the tumour/lesion was within the resection specimen. Preoperative tumour localisation is extremely important to correctly identify the site of tumour or lesion at laparoscopy. A standardised departmental protocol should be implemented by all endoscopists to place three spots of tattoo one mucosal fold distal to any significant lesions found. Failure to tattoo lesions/cancers preoperatively can lead to intraoperative delays and

Hypotension is common in patients undergoing surgery in the sitting position under general anesthesia, and the risk may be exacerbated by the use of antihypertensive drugs taken preoperatively. The purpose of this study was to compare hypotensive episodes in patients taking antihypertensive medications with normotensive patients during shoulder surgery in the beach chair position. Medical records of all patients undergoing shoulder arthroscopy during a 44-month period were reviewed retrospectively. The primary endpoint was the number of moderate hypotensive episodes (systolic blood pressure ≤ 85 mmHg) during the intraoperative period. Secondary endpoints included the frequency of vasopressor administration, total dose of vasopressors, and fluid administered. Values are expressed as mean (standard deviation). Of 384 patients who underwent shoulder surgery, 185 patients were taking no antihypertensive medication, and 199 were on at least one antihypertensive drug. The antihypertensive medication group had more intraoperative hypotensive episodes [1.7 (2.2) vs 1.2 (1.8); P = 0.01] and vasopressor administrations. Total dose of vasopressors and volume of fluids administered were similar between groups. The timing of the administration of angiotensin-converting enzyme inhibitors and of angiotensin receptor antagonists (≤ 10 hr vs > 10 hr before surgery) had no impact on intraoperative hypotension. Preoperative use of antihypertensive medication was associated with an increased incidence of intraoperative hypotension. Compared with normotensive patients, patients taking antihypertensive drugs preoperatively are expected to require vasopressors more often to maintain normal blood pressure.

Enhanced magnetic resonance imaging (MRI) and ultrasonography (US) are used to assess residual lesions after preoperative chemotherapy before surgery. However, residual lesion assessments based on preoperative imaging often differ from postoperative pathologic diagnoses. We retrospectively reviewed the accuracy of preoperative residual lesion assessments, including ductal carcinoma in situ (DCIS) cases to find criteria for cases in which surgery can be omitted. We reviewed 201 patients who received preoperative chemotherapy and surgery in our hospital from January 2013 to November 2016. Presurgical evaluations regarding the possible existence of residual lesions, and clinical Complete Response (cCR) or non-cCR, were compared with postoperative pathological diagnoses. Of the 201 patients, 52 were diagnosed with cCR, and 39 with pathological complete response (pCR). Predictions for residual lesions were 86.4% sensitive, 76.9% specific, and 84.6% accurate. When patients were divided into 4 groups by estrogen receptor (ER) and HER2 status, sensitivity in each group was ER + /HER2 - : 91.4%; ER - /HER2 - : 94.1%; ER + /HER2 + : 78.6%; and ER - /HER2 + : 78.5%. Of the 22 patients preoperatively assessed with cCR, but diagnosed with non-pCR, the median invasive residual tumor size was 2 mm (range 0-46 mm); 5 patients (22.7%) had only DCIS. Predicting residual lesions after preoperative chemotherapy by using MRI and US is a reasonable strategy. However, current methods are inadequate for identifying patients who can omit surgery; therefore, a new strategy for detecting small tumors in these patients is needed.

Full Text Available BackgroundSeveral inflammatory biomarkers, especially a high preoperative neutrophil-to-lymphocyte count ratio (NLR and platelet-to-lymphocyte count ratio (PLR, are known to be indicator of poor prognosis in several cancers. However, very few studies have evaluated the significance of the NLR and PLR in papillary thyroid cancer (PTC. We evaluated the association of the preoperative NLR and PLR with clinicopathological characteristics in patients with PTC.MethodsThis study included 1,066 female patients who underwent total thyroidectomy for PTC. Patients were stratified into 4 quartiles by preoperative NLR and PLR. And the combination of preoperative NLR and PLR was calculated on the basis of data obtained value of tertile as follows: patients with both an elevated PLR and an elevated NLR were allocated a score of 2, and patients showing one or neither were allocated a score of 1 or 0, respectively.ResultsThe preoperative NLR and PLR were significantly lower in patients aged ≥45 years and in patients with Hashimoto's thyroiditis. The PLR was significantly higher in patients with tumor size >1 cm (P=0.021.When the patients were categorized into the aforementioned four groups, the group with the higher preoperative PLR was found to have a significantly increased incidence of lateral lymph node metastasis (LNM (P=0.018. However, there are no significant association between the combination of preoperative NLR and PLR and prognostic factors in PTC patients.ConclusionThese results suggest that a preoperative high PLR were significant associated with lateral LNM in female patients with PTC.

The aim of this study was to examine the potential relationship between subjective sleep quality and degree of pain in patients with rotator cuff repair. Thirty-one patients who underwent rotator cuff repair prospectively completed the Pittsburgh Sleep Quality Index, the Western Ontario Rotator Cuff Index, and the Constant and Murley shoulder scores before surgery and at 6 months after surgery. Preoperative demographic, clinical, and radiologic parameters were also evaluated. The study analysed 31 patients with a median age of 61 years. There was a significant difference preoperatively versus post-operatively in terms of all PSQI global scores and subdivisions (p Rotator Cuff Scale and the Constant and Murley shoulder scores (p ˂ 0.001). Sleep disorders are commonly seen in patients with rotator cuff tear, and after repair, there is an increase in the quality of sleep with a parallel improvement in shoulder functions. However, no statistically significant correlation was determined between arthroscopic procedures and the size of the tear and sleep quality. It is suggested that rotator cuff tear repair improves the quality of sleep and the quality of life. IV.

In Germany the predominant standard of preoperative care for elective surgery is fasting after midnight, with the aim of reducing the risk of pulmonary aspiration. However, for the past several years the scientific evidence supporting such a practice has been challenged. Experimental and clinical studies prove a reliable gastric emptying within 2 h suggesting that, particularly for limited intake of clear fluids up to 2 h preoperatively, there would be no increased risk for the patient. In addition, the general incidence of pulmonary aspiration during general anaesthesia (before induction, during surgery and during recovery) is extremely low, has a good prognosis and is more a consequence of insufficient airway protection and/or inadequate anaesthetic depth rather than due to the patient's fasting state. Therefore, primarily to decrease perioperative discomfort for patients, several national anaesthesia societies have changed their guidelines for preoperative fasting. They recommend a more liberal policy regarding per os intake of both liquid and solid food, with consideration of certain conditions and contraindications. The following article reviews the literature and gives an overview of the scientific background on which the national guidelines are based. The intention of this review is to propose recommendations for preoperative fasting regarding clear fluids for Germany as well.

To describe the proportion of patients allergic to β-lactam antibiotics and the prevalence of preoperative conjunctival bacteria among those undergoing cataract surgery in our area. Retrospective cross-sectional study of prevalence of β-lactam allergic patients consecutively scheduled for cataract surgery from 11 July 2005 to November 2012. For studying the prevalence of conjunctival bacteria and clinical characteristics in the patients' preoperative examination, those under 18 years and those with cataract surgery combined with other eye surgeries were excluded. Data from the first preoperative examination of the remaining patients were selected. Clinical data were extracted from the database generated in the evaluation made for anesthetic purposes, and the microbiological data from the laboratory database. Both bases were linked through a patient history code. A comparison was made between the prevalence of conjunctival bacteria and clinical characteristics in allergic and non-allergic patients. From 12,409 adults selected for the bacteriological study, 862 (6.96%) were allergic to β-lactams, their mean age (74.45 years) was higher than that of the non-allergic (P=.005). The proportion of women (71.4%) in the allergic patient group was much higher than that of men. The prevalence of pathogenic bacteria (especially Bacillus spp and Pseudomonas aeruginosa), lung disease and heart failure, was higher in allergic patients. The prevalence of allergy to β-lactams in this study is within the range described in other populations. The higher prevalence of pathogenic bacteria and the predominance of women in those allergic to β-lactams are useful data to guide their surgical prophylaxis.

Noninvasive localization of brain function is used to understand and treat neurological disease, exemplified by pre-operative fMRI mapping prior to neurosurgical intervention. The principal approach for generating these maps relies on brain responses evoked by a task and, despite known limitations, has dominated clinical practice for over 20 years. Recently, pre-operative fMRI mapping based on correlations in spontaneous brain activity has been demonstrated, however this approach has its own limitations and has not seen widespread clinical use. Here we show that spontaneous and task-based mapping can be performed together using the same pre-operative fMRI data, provide complimentary information relevant for functional localization, and can be combined to improve identification of eloquent motor cortex. Accuracy, sensitivity, and specificity of our approach are quantified through comparison with electrical cortical stimulation mapping in eight patients with intractable epilepsy. Broad applicability and reproducibility of our approach is demonstrated through prospective replication in an independent dataset of six patients from a different center. In both cohorts and every individual patient, we see a significant improvement in signal to noise and mapping accuracy independent of threshold, quantified using receiver operating characteristic curves. Collectively, our results suggest that modifying the processing of fMRI data to incorporate both task-based and spontaneous activity significantly improves functional localization in pre-operative patients. Because this method requires no additional scan time or modification to conventional pre-operative data acquisition protocols it could have widespread utility. PMID:26408860

Carotid endarterectomy (CEA) for asymptomatic carotid artery stenosis is among the most common procedures performed in the United States. However, consensus is lacking regarding optimal preoperative imaging, carotid duplex ultrasound criteria, and ultimately, the threshold for surgery. We sought to characterize national variation in preoperative imaging, carotid duplex ultrasound criteria, and threshold for surgery for asymptomatic CEA. The Society for Vascular Surgery Vascular Quality Initiative (VQI) database was used to identify all CEA procedures performed for asymptomatic carotid artery stenosis between 2003 and 2014. VQI currently captures 100% of CEA procedures performed at >300 centers by >2000 physicians nationwide. Three analyses were performed to quantify the variation in (1) preoperative imaging, (2) carotid duplex ultrasound criteria, and (3) threshold for surgery. Of 35,695 CEA procedures in 33,488 patients, the study cohort was limited to 19,610 CEA procedures (55%) performed for asymptomatic disease. The preoperative imaging modality used before CEA varied widely, with 57% of patients receiving a single preoperative imaging study (duplex ultrasound imaging, 46%; computed tomography angiography, 7.5%; magnetic resonance angiography, 2.0%; cerebral angiography, 1.3%) and 43% of patients receiving multiple preoperative imaging studies. Of the 16,452 asymptomatic patients (89%) who underwent preoperative duplex ultrasound imaging, there was significant variability between centers in the degree of stenosis (50%-69%, 70%-79%, 80%-99%) designated for a given peak systolic velocity, end diastolic velocity, and internal carotid artery-to-common carotid artery ratio. Although 68% of CEA procedures in asymptomatic patients were performed for an 80% to 99% stenosis, 26% were performed for a 70% to 79% stenosis, and 4.1% were performed for a 50% to 69% stenosis. At the surgeon level, the range in the percentage of CEA procedures performed for a duplex ultrasound

Language mapping by repetitive navigated transcranial magnetic stimulation (rTMS) is used for resection planning in patients suffering from brain lesions within regions known to be involved in language function. Yet we also need data that show whether patients benefit clinically from preoperative rTMS for language mapping. We enrolled 25 patients with language eloquently located brain lesions undergoing preoperative rTMS language mapping (GROUP 1, 2011-2013), with the mapping results not being available for the surgeon, and we matched these patients with 25 subjects who also underwent preoperative rTMS (GROUP 2, 2013-2014), but the mapping results were taken into account during tumor resection. Additionally, cortical language maps were generated by analyzing preoperative rTMS and intraoperative direct cortical stimulation (DCS) data. Mean anterior-posterior (ap) craniotomy extents and overall craniotomy sizes were significantly smaller for the patients in GROUP 2 (Ap: p = 0.0117; overall size: p = 0.0373), and postoperative language deficits were found significantly more frequently for the patients in GROUP 1 (p = 0.0153), although the preoperative language status did not differ between groups (p = 0.7576). Additionally, there was a trend towards fewer unexpected tumor residuals, shorter surgery duration, less peri- or postoperative complications, shorter inpatient stay, and higher postoperative Karnofsky performance status scale (KPS) for the patients in GROUP 2. The present study provides a first hint that the clinical course of patients suffering from brain tumors might be improved by preoperative rTMS language mapping. However, a significant difference between both groups was only found for craniotomy extents and postoperative deficits, but not for other clinical parameters, which only showed a trend toward better results in GROUP 2. Therefore, multicenter trials with higher sample sizes are needed to further investigate the distinct impact of r

To reduce intraoperative and postoperative complications, using Lugol solution to preoperatively prepare patients with Graves' disease has (1) rapidly reduced the severity of thyrotoxicosis and (2) reduced the vascularity of the thyroid gland. The vascularity reduction normally accompanies reducing the severity of thyrotoxicosis. However, the effects and mechanism of Lugol solution for reducing blood flow have not been well investigated in the patients with euthyroid (normally functioning thyroid) Graves' disease. Twenty-five patients with euthyroid Graves' disease being preoperatively treated with Lugol solution for 10 days were measured, at baseline and on the operative day, for (1) superior thyroid artery blood flow; (2) systemic angiogenic factor (VEGF); and (3) systemic inflammatory factor [interleukin (IL)-16]. All three parameters were significantly (p Graves' disease. We recommend routine preoperative Lugol solution treatment for all patients with Graves' disease.

Optimal perioperative pain control regimens remain challenging and opioid analgesics are commonly used. Preoperative nonsteroidal anti-inflammatory drug (NSAID administration has been shown to reduce postoperative narcotic requirements. This study sought to evaluate the efficacy of perioperative intravenous (IV ibuprofen on postoperative pain level and narcotic use in patients undergoing open or laparoscopic inguinal and/or umbilical hernia repair.Methods: A single center, randomized, double-blind placebo-controlled trial involving patients ≥18 years undergoing inguinal and/or umbilical hernia repair was performed. Patients were randomized to receive 800 mg of IV ibuprofen or placebo preoperatively. Outcomes assessed included postoperative pain medication required and visual analog scale (VAS pain scores.Results: Forty-eight adult male patients underwent inguinal and/or umbilical hernia repair. Patients receiving IV ibuprofen used more oxycodone/acetaminophen (32% vs 13% and IV hydromorphone (12% vs 8.7%, and fewer combinations of pain medications (44% vs 65.2% in the first two postoperative hours compared to placebo (p=0.556.

Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

The role of pre-operative breast MRI is outlined on the basis of the existing evidence in favor of a superior capability in comparison with mammography and sonography to detect ipsilateral and contralateral malignant lesions and to evaluate the disease extent, including the extensive intraductal component associated with invasive cancers. Patients with a potential higher anticipated benefit from pre-operative MRI can be identified as those: with mammographically dense breasts; with a unilateral multifocal/multicentric cancer or a synchronous bilateral cancer already diagnosed at mammography and sonography; with a lobular invasive cancer; at high-risk for breast cancer; with a cancer which shows a discrepancy in size of >1 cm between mammography and sonography; or under consideration for partial breast irradiation. More limited evidence exists in favor of MRI for evaluating candidates for total skin sparing mastectomy or for patients with Paget's disease. Irrespective of whether the clinical team routinely uses preoperative MRI or not: women newly diagnosed with breast cancer should always be informed of the potential risks and benefits of pre-operative MRI; results of pre-operative MRI should be interpreted taking into account clinical breast examination, mammography, sonography and verified by percutaneous biopsy; MRI-only detected lesions require MR-guidance for needle biopsy and pre-surgical localization, and these should be available or potentially accessible if pre-operative MRI is to be implemented; total therapy delay due to pre-operative MRI (including MRI-induced work-up) should not exceed one month; changes in therapy planning resulting from pre-operative MRI should be decided by a multidisciplinary team.

Full Text Available Objective. To determine if routine preoperative and intraoperative urine cultures (UCx are necessary in pediatric vesicoureteral (VUR reflux surgery by identifying their association with each other, preoperative symptoms, and surgical outcomes. Materials and Methods. A retrospective review of patients undergoing ureteral reimplant(s for primary VUR at a tertiary academic medical center between years 2000 and 2014 was done. Preoperative UCx were defined as those within 30 days before surgery. A positive culture was defined as >50,000 colony forming units of a single organism. Results. A total of 185 patients were identified and 87/185 (47.0% met inclusion criteria. Of those, 39/87 (45% completed a preoperative UCx. Only 3/39 (8% preoperative cultures returned positive, and all of those patients were preoperatively symptomatic. No preoperatively asymptomatic patients had positive preoperative cultures. Intraoperative cultures were obtained in 21/87 (24.1% patients; all were negative. No associations were found between preoperative culture results and intraoperative cultures or between culture result and postoperative complications. Conclusions. In asymptomatic patients, no associations were found between the completion of a preoperative or intraoperative UCx and surgical outcomes, suggesting that not all patients may require preoperative screening. Children presenting with symptoms of urinary tract infection (UTI prior to ureteral reimplantation may benefit from preoperative UCx.

Effects of preoperative one week enteral nutrition (EN) support on the postoperative nutritional status, immune function and inflammatory response of gastric cancer patients were investigated. 106 cases of gastric cancer patients were randomly divided into preoperative one week EN group (trial group) and early postoperative EN group (control group), which were continuously treated with EN support until the postoperative 9th day according to different treatment protocols. All the patients were checked for their body weight, skinfold thickness, upper arm circumference, white blood cell count (WBC), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), humoral immunity (IgA, IgG), T cell subsets (CD4, CD8 and CD4/CD8), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), etc. on the preoperative and the postoperative 1st and 10th day, respectively. PA and IgG levels of the experimental group were higher than those of the control group on the postoperative 10th day, whereas IL-6 level of the experimental group was lower than that of the control group. EN support for preoperative gastric cancer patients will improve the postoperative nutritional status and immune function, alleviate inflammatory response, and facilitate the recovery of patients.

Parents feel fear and anxiety before surgery is performed on their child, and those feelings could obstruct their preparation for the surgery. Preoperative information could relieve those feelings. To determine the preoperative information needs of parents of children undergoing elective surgery. A study was conducted on the parents of children who underwent elective surgery. Demographic data of parents were recorded. Preoperative information received or would like to have received was assessed in terms of contents, methods, opportunity, place and informant. Descriptive statistics were used. Thirteen hundred parents were surveyed. More than 80% of them want preoperative information about anaesthesia, surgery, preoperative fasting, drugs and anaesthetic complications, monitoring, intravenous line management, pain treatment, postoperative feeding, anxiety control, hospitalisation room, recovery room, and entertainment in recovery room. Most want to be informed verbally, one to two weeks in advance and not on the same day of surgery. The informant should be the surgeon and in his office. In addition, they want information through leaflets, videos and simulation workshops, or guided tours. Parents need complete preoperative information about anesthesia, surgery and postoperative care, received verbally and in advance. Copyright © 2015 Sociedad Chilena de Pediatría.

Preoperative anxiety is commonly reported by people undergoing surgery. A significant number of studies have found a correlation between preoperative anxiety and post-operative morbidity. Various methods of complementary and alternative medicine (CAM) were found to be effective in alleviating preoperative anxiety. This study examined the relative effectiveness of various individual and generic CAM methods combined with standard treatment (ST) in relieving preoperative anxiety, in comparison with ST alone. Randomized controlled trial. Holding room area Three hundred sixty patients. Patients were randomly divided into 6 equal-sized groups. Group 1 received the standard treatment (ST) for anxiety alleviation with anxiolytics. The five other groups received the following, together with ST (anxiolytics): Compact Disk Recording of Guided Imagery (CDRGI); acupuncture; individual guided imagery; reflexology; and individual guided imagery combined with reflexology, based on medical staff availability. Assessment of anxiety was taken upon entering the holding room area (surgery preparation room) ('pre-treatment assessment'), and following the treatment, shortly before transfer to the operating room ('post-treatment assessment'), based on the Visual Analogue Scale (VAS) questionnaire. Data processing included comparison of VAS averages in the 'pre' and 'post' stages among the various groups. Preoperatively, CAM treatments were associated with significant reduction of anxiety level (5.54-2.32, peffective than individualized CAM (Peffective than generic CDRGI. In light of the scope of preoperative anxiety and its implications for public health, integration of CAM therapies with ST should be considered for reducing preoperative anxiety.

It remains unclear whether the preoperative pulmonary function parameters and prognostic indices that are indicative of nutritional and immunological status are associated with prognosis in lung cancer patients with combined pulmonary fibrosis and emphysema (CPFE) who have undergone surgery. The aim of this study is to identify prognostic determinants in these patients. The medical records of all patients with lung cancer associated with CPFE who had undergone surgery at Shinshu University Hospital were retrospectively reviewed to obtain clinical data, including the results of preoperative pulmonary function tests and laboratory examinations, chest high-resolution computed tomography (HRCT), and survival. Univariate Cox proportional hazards regression analysis showed that a high pathological stage of the lung cancer, a higher preoperative serum carcinoembryonic antigen level, and a higher preoperative composite physiologic index (CPI) were associated with a high risk of death. Multivariate analysis showed that a high pathological stage of the lung cancer (HR: 1.579; p = 0.0305) and a higher preoperative CPI (HR: 1.034; p = 0.0174) were independently associated with a high risk of death. In contrast, the severity of fibrosis or emphysema on chest HRCT, the individual pulmonary function parameters, the prognostic nutritional index, the neutrophil-to-lymphocyte ratio, and the platelet-to-lymphocyte ratio were not associated with prognosis. In the Kaplan-Meier analysis, the log-rank test showed significant differences in survival between the high-CPI and the low-CPI group (p = 0.0234). The preoperative CPI may predict mortality and provide more powerful prognostic information than individual pulmonary function parameters in lung cancer patients with CPFE who have undergone surgery. © 2017 S.

The undetectable supernumerary and ectopic parathyroid glands have a high risk of persistent and recurrent hyperparathyroidism, especially in the patients with secondary hyperparathyroidism. Preoperative image diagnosis, CT scan, echogram and 201 TlCl scintigram were very useful for detecting supernumerary and ectopic parathyroid glands in our 132 patients who underwent parathyroidectomy for secondary hyperparathyroidism. Among these methods the scintigraphy showed the highest detection rate of the glands located in the thyroid gland and those located between the thyroid gland and trachea. The echography was useful in detecting the glands in the thyroid gland, but could not offer easy visualization those located in the mediastinum. Even the ectopic parathyroid glands, weighing more than 500 mg were identifiable at about 90% when all the methods were applied routinely. In our experience, four patients had a supernumerary gland which was detected by the preoperative image diagnostic procedures at the initial surgery. One patient had a supernumerary gland in the mediastinum which was detected by image diagnosis after the initial operation and was removed at reoperation. (author)

Purpose: To define failure patterns and predictive factors in esophageal cancer patients who had a pathologic complete response (pCR) after preoperative concurrent chemoradiotherapy (PCRT). Methods and Materials: We performed a retrospective analysis of 61 esophageal cancer patients who were enrolled in prospective studies and showed pCR after PCRT. All of the patients had squamous cell carcinoma. Of the patients, 40 were treated with hyperfractionated radiotherapy (4,560 cGy in 28 fractions) with 5-fluorouracil (5-FU) and cisplatin (FP), and 21 patients received conventional fractionation radiotherapy with capecitabine and cisplatin (XP). Results: The median follow-up time was 45.2 months (range, 6.5-162.3 months). The 5-year overall survival (OS) and disease-free survival rates (DFS) were 60.2% and 80.4%, respectively. In univariate analysis, age and lymph node (LN) metastasis were poor prognostic factors for OS, and pretreatment weight loss (>2 kg) was a poor prognostic factor for DFS. In multivariate analysis, lymph node metastasis and pretreatment weight loss were independent prognostic factors for OS and DFS. Nine patients (15%) had disease recurrence. Of the nine patients, 5 patients had locoregional failure, 1 patients had distant metastasis, and 3 patients had distant and locoregional failure. In-field failure occurred in 5 patients; out-of-field failure occurred in 1 patient; both in-field and out-of-field failure occurred in 2 patients; and both marginal and out-of-field failure occurred in 1 patient. Conclusions: Even in pCR patients, the most common failure site was within the radiation field, which suggests that more efficient local treatment is needed. Tumor recurrence was more common in patients with older age and with pretreatment weight loss.

The purpose of this study was to investigate the prevalence of preoperative psychological distress and its relationship with coping style and quality of life in Chinese patients with newly diagnosed gastric cancer. Being newly diagnosed with cancer can be a source of psychological distress. Understanding the preoperative psychological distress may contribute to the development of appropriate interventions. This is a descriptive correlational survey study. The study was conducted in two teaching hospitals in Anhui province, China. A total of 165 patients with gastric cancer completed a battery of self-report questionnaires including the Distress Thermometer, the revised Chinese version of the Quality of Life Questionnaire-Stomach 22 and the Cancer Coping Modes Questionnaire. The prevalence of clinically significant preoperative psychological distress was 76·97% in this group. Statistically significant correlations were identified between the distress score and stomach pain, eating restrictions and anxiety subscale. Positive associations were found between the distress scores and four subdimensions of coping (avoidance and suppression, resignation, fantasy and catharsis), whereas a negative association was found between the distress scores and one subdimension of coping (Confrontation). There were also significant differences in the quality of life and coping style of patients who had different psychological distress statuses. These findings indicate a relatively high prevalence of preoperative psychological distress among Chinese patients with gastric cancer. Patients with clinically psychological distress were more likely to have poor quality of life and to demonstrate negative coping styles. Nursing professionals need to carefully assess the psychological status of patients with gastric cancer. Tailored interventions can be administered to help these patients appropriately cope with the disease and to enhance their quality of life. © 2015 John Wiley & Sons Ltd.

Total knee arthroplasty (TKA) is the preferred surgical treatment for end-stage osteoarthritis. However, substantial numbers of patients still experience poor outcomes. Consequently, it is important to identify which patient characteristics are predictive of outcomes in order to guide clinical decisions. Our hypothesis is that preoperative patient-reported outcome measures and radiographic measures may help to predict TKA outcomes. Using cohort data from the Osteoarthritis Initiative, we studied 172 patients who underwent TKA. For each patient, we compiled pre- and postoperative Western Ontario and McMaster University Arthritis Index (WOMAC) scores. Radiographs were measured for knee joint angles, femorotibial angles, anatomical lateral distal femoral angles, and anatomical medial proximal tibial angles; Kellgren and Lawrence (KL) grades were assigned to each compartment of the knee. All studied measurements were compared to WOMAC outcomes. Preoperative WOMAC disability, pain, and total scores were positively associated with postoperative WOMAC total scores (P = .010, P = .010, and P = .009, respectively) and were associated with improvement in WOMAC total scores (P < .001, P < .001, and P < .001, respectively). For radiographic measurements, preoperative joint angles were positively associated with improvements in postoperative WOMAC total scores (P = .044). Combined KL grades (medial and lateral compartments) were negatively correlated with postoperative WOMAC disability and pain scores (P = .045 and P = .044) and were positively correlated with improvements in WOMAC total scores (P = .001). All preoperative WOMAC scores demonstrated positive associations with postoperative WOMAC scores, while among the preoperative radiographic measurements only combined KL grades and joint angles showed any correlation with postoperative WOMAC scores. Higher preoperative KL grades and joint angles were associated with better (lower) postoperative WOMAC scores, demonstrating an

To assess the feasibility of a pre-operative occupational therapy intervention for patients undergoing primary total hip replacement. Single blinded feasibility randomised controlled trial, with data collection prior to the intervention, and at 4, 12, and 26 weeks following surgery. Recruitment from two NHS orthopaedic outpatient centres in the West Midlands, UK. Patients awaiting primary total hip replacement due to osteoarthritis were recruited. Following pre-operative assessment, patients were individually randomised to intervention or control by a computer-generated block randomisation algorithm stratified by age and centre. The intervention group received a pre-surgery home visit by an occupational therapist who discussed expectations, assessed home safety, and provided appropriate adaptive equipment. The control group received treatment as usual. The study assessed the feasibility of recruitment procedures, delivery of the intervention, appropriateness of outcome measures and data collection methods. Health related quality of life and resource use were recorded at 4, 12 and 26 weeks. Forty-four participants were recruited, 21 were randomised to the occupational therapy intervention and 23 to usual care. Analysis of 26 week data included 18 participants in the intervention group and 21 in the control. The intervention was delivered successfully with no withdrawals or crossovers; 5/44 were lost to follow-up with further missing data for participation and resource use. The feasibility study provided the information required to conduct a definitive trial. Burden of assessment would need to be addressed. A total of 219 patients would be required in an efficacy trial. © The Author(s) 2015.

Patients with rectal cancer have issues in adjusting to their permanent colostomy after surgery, and support is required to help them resume normal life. However, few studies have explored the experience and factors that affect a patient's decision-making and maladjustment prior to colostomy surgery. The aim of this study was to explore the experience of rectal cancer patients who have to undergo colostomy surgery. A descriptive, qualitative design was used. We studied a purposive sample of 18 patients who had received a diagnosis of primary rectal cancer and were expecting permanent colostomy surgery. The thematic analysis approach was used to analyze the data collected using semi-structured, open-ended questions. The overriding theme that emerged was 'stoma dilemma: a hard decision-making process'. From this main theme, three themes were derived: the resistance stage, the hesitation stage, and the acquiescence stage. It is hard for preoperative rectal patients to choose to undergo stoma surgery or a sphincter-saving operation. From the initial stage of definitive diagnosis to the final consent to stoma surgery, most patients experience the resistance and hesitation stages before reaching the acquiescence stage. Arriving at a decision is a process that nurses can facilitate by eliminating unnecessary misunderstanding surrounding colostomy surgery and by fully respecting patients' right to choose at the various stages.

Preoperative immobility in general surgery patients has been associated with an increased risk of postoperative complications. It is unknown if immobility affects bariatric surgery outcomes. The aim of this study was to determine the impact of immobility on 30-day postoperative bariatric surgery outcomes. This study took place at a university hospital in the United States. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. Preoperative immobility was defined as limited ambulation most or all the time. Logistic regression analysis was performed to determine if immobile patients are at increased risk (odds ratio [OR]) for 30-day complications. There were 148,710 primary minimally invasive bariatric procedures in 2015. Immobile patients had an increased risk of mortality (OR 4.59, Pbariatric surgery outcomes. Immobile patients have a significantly increased risk of morbidity and mortality. This study provides an opportunity for the development of multiple quality initiatives to improve the safety and perioperative complication profile for immobile patients undergoing bariatric surgery.

Preoperative nutritional status not only correlates with the incidence of postoperative complications but also may be indicative of long-term outcomes for patients with cancer. The impact of preoperative nutritional status on outcomes for patients undergoing gastrectomy for gastric cancer (GC) was investigated. The study reviewed 594 patients treated for GC by gastrectomy at the authors' hospital between January, 2004 and December, 2010. Onodera's prognostic nutritional index (PNI) was invoked, using an optimal cut point to group patients as having high (PNI > 45; n = 449) or low (PNI ≤ 45; n = 145) nutritional status. Clinicopathologic features, perioperative results, and long-term outcomes, including cause of death, were compared. Multivariate analysis of 5-year overall survival (OS) and disease-specific survival (DSS) indicated that low PNI was independently associated with unfavorable outcomes for patients with GC. In subgroup analysis, the 5-year OS and DSS rates for patients with GC at stages 1 and 2 were significantly worse in the low PNI group than in the high PNI group. Although wound and extrasurgical field infections also tended to be more frequent in the low PNI group, postoperative intraabdominal infections did not differ significantly by group. Preoperative PNI may have merit as a gauge of prognosis for patients with GC at stages 1 and 2, but PNI and postoperative morbidity showed no correlation in this setting.

1986-01-01

The effect of adjuvant preoperative treatments with radiation and 5-fluorouracil (5-FU) on rectal carcinomas was investigated. The radiation therapy was administered in the area including the rectum and regional lymph nodes up to the level of the promontorium with 10 doses of 300 rad in three-week periods (a total dose of 3,000 rad). The suppository containing 100 mg of 5-FU was given intrarectally twice daily in the same period (a total dose of 4,000 mg of 5-FU). The surgical procedure with either abdominoperineal excision or anterior resection was performed within 14 days after the last preoperative treatment. The resected specimens were examined microscopically. The mean thickness of excised tumor-free tissue around the rectal wall having the most extended tumor growth was 6.2 mm in 16 patients receiving the treatment with radiation and 5-FU, 3.9 mm in 31 patients with 5-FU alone and 3.7 mm in 19 patients without preoperative treatments. Lymph node metastases were detected in 3 of 17 patients (19 %) with radiation and 5-FU, in 18 of 33 patients (55 %) with 5-FU alone, and in 11 of 24 patients (46 %) without preoperative treatments. The extensive degenerative pictures of cancer cells such as nuclear picnosis, and the growth of collagen fibers in carcinoma foci were observed in resected specimens with radiation and 5-FU treatments. Those findings suggest that preoperative adjuvant therapy with moderate dose of radiation and 5-FU affected significantly rectal carcinomas. There were no adverse effects. It seems likely, thus, that this combined therapy could prevent postoperative local or intrapelvic recurrence, which was the most frequent form of recurrence after curative surgery in rectal cancer.

The goal of this retrospective study was to investigate the efficacy and safety of preoperative chemoradiotherapy (NACR) in patients with Stage 2 or Stage 3 esophageal squamous cell carcinoma (SCC). Between 2004 and 2014, a total of 86 patients underwent surgical resection in conjunction with NACR for esophageal SCC at our institute. Thirty-one patients (36.0%) had Stage 2 disease and 55 patients (64.0%) had Stage 3 disease. The median age was 64 (43-81) years. A total of 78 patients received the full NACR regimen. The most common major Grade 3 hematologic toxic effects of NACR were leukopenia and neutropenia (48 cases), while the most common major Grade 3 non-hematologic toxic effect was anorexia (12 cases). One patient died in the hospital and no patients died within 30 days after surgery. A pathological complete response was achieved in 23 cases. Pathological staging (number of cases) was Stage 0 (23), Stage 1 (8), Stage 2 (28), Stage 3 (25), and Stage 4 (2). The 5-year overall survival rate (OS) was 51.0%, and was 83.2% in Stage 2 patients and 29.9% in Stage 3 patients. Preoperative NACR is safe and may improve OS and down-staging rates in patients with esophageal SCC. (author)

Although the skeletal muscle in the region of the third lumbar vertebra (L3) is generally assessed in order to judge sarcopenia, not every patient with non-small cell lung cancer (NSCLC) undergoes computed tomography including the L3 region. We hypothesized that immuno-nutritional parameters could predict the existence of sarcopenia in patients with NSCLC. The aim of this study was to retrospectively investigate the correlation between preoperative sarcopenia and immuno-nutritional parameters in patients with early-stage NSCLC. We selected 147 of patients with pathological stage I NSCLC who underwent preoperative measurement of immuno-nutritional parameters and CT including the L3 region. Preoperative sarcopenia was significantly associated with female gender (p=0.0003) and poor prognosis (p=0.0322). In Kaplan-Meier analysis of overall survival (OS) by preoperative sarcopenia status, the sarcopenic group had significantly shorter OS than the non-sarcopenic group (5-year OS: 87.27% vs. 77.37%, p=0.0131, log-rank test). In multivariate analysis, the preoperative sarcopenia status (hazard ratio=5.138; 95% confidence interval=2.305-11.676; psarcopenia status was significantly related to controlling nutritional status score (p=0.0071) and Geriatric Nutritional Risk Index (GNRI) (psarcopenia status and GNRI (r=0.348, psarcopenia which was associated with poor outcome in patients with early-stage NSCLC.

Surgical site infection is a major cause of morbidity after colorectal resections. Despite evidence that preoperative oral antibiotics with mechanical bowel preparation reduce surgical site infection rates, the use of oral antibiotics is decreasing. Currently, the administration of oral antibiotics is controversial and considered ineffective without mechanical bowel preparation. The aim of this study is to examine the use of mechanical bowel preparation and oral antibiotics and their relationship to surgical site infection rates in a colorectal Surgical Care Improvement Project cohort. This retrospective study used Veterans Affairs Surgical Quality Improvement Program preoperative risk and surgical site infection outcome data linked to Veterans Affairs Surgical Care Improvement Project and Pharmacy Benefits Management data. Univariate and multivariable models were performed to identify factors associated with surgical site infection within 30 days of surgery. This study was conducted in 112 Veterans Affairs hospitals. Included were 9940 patients who underwent elective colorectal resections from 2005 to 2009. The primary outcome measured was the incidence of surgical site infection. Patients receiving oral antibiotics had significantly lower surgical site infection rates. Those receiving no bowel preparation had similar surgical site infection rates to those who had mechanical bowel preparation only (18.1% vs 20%). Those receiving oral antibiotics alone had an surgical site infection rate of 8.3%, and those receiving oral antibiotics plus mechanical bowel preparation had a rate of 9.2%. In adjusted analysis, the use of oral antibiotics alone was associated with a 67% decrease in surgical site infection occurrence (OR=0.33, 95% CI 0.21-0.50). Oral antibiotics plus mechanical bowel preparation was associated with a 57% decrease in surgical site infection occurrence (OR=0.43, 95% CI 0.34-0.55).

Strontium nitrate Sr-87m bone scans were made preoperatively in a group of women with suspected breast cancer, 35 of whom subsequently underwent radical mastectomy. In 3 of the 35 (9 percent), the scans were abnormal despite the absence of clinical or roentgenographic evidence of metastatic disease. All three patients had extensive axillary lymph node involvement by tumor, and went on to have additional bone metastases, from which one died. Roentgenograms failed to detect the metastases in all three. Occult bone metastases account in part for the failure of radical mastectomy to cure some patients with breast cancer. It is recommended that all candidates for radical mastectomy have a preoperative bone scan. (U.S.)

Purpose: To determine if preoperative radiation therapy allows sphincter preservation in the treatment of rectal cancer. Methods and Materials: Thirty patients with the diagnosis of invasive, resectable, primary adenocarcinoma of the rectum limited to the pelvis were enrolled on a Phase I/II trial of preoperative radiation therapy plus low anterior resection/coloanal anastomosis. By preoperative assessment, all patients had invasive tumors (2: T2, 28: T3) involving the distal half of the rectum and required an abdominoperineal resection. The median tumor size was 4 cm (range: 1.5-6 cm) and the median distance from the anal verge was 4 cm (range: 3-7 cm). The whole pelvis received 46.8 Gy followed by a 3.60 Gy boost to the primary tumor bed. The median follow-up was 43 months (range: 6-82 months). Results: Of the 29 patients who underwent resection, 3 (10%) had a complete pathologic response and 24 (83%) were able to successfully undergo a low anterior resection/coloanal anastomosis. The incidence of local failure was crude: 17% and 4-year actuarial: 23%. The 4-year actuarial survival was 75%. One patient developed a partial disruption of the anastomosis and two developed rectal stenosis. Analysis of sphincter function using a previously published scale was performed at the time of last follow-up in 22 of the 24 patients who underwent a low anterior resection/coloanal anastomosis. Function was good or excellent in 77%. The median number of bowel movements/day was two (range: 1-6). Conclusions: This technique may be an alternative to an abdominoperineal resection in selected patients. Continued follow-up is needed to determine if this approach ultimately has similar local control and survival rates as an abdominoperineal resection

Purpose: To determine if preoperative radiation therapy allows sphincter preservation in the treatment of rectal cancer. Methods and Materials: Thirty patients with the diagnosis of invasive, resectable, primary adenocarcinoma of the rectum limited to the pelvis were enrolled on a Phase I/II trial of preoperative radiation therapy plus low anterior resection/coloanal anastomosis. By preoperative assessment, all patients had invasive tumors (2: T2, 28: T3) involving the distal half of the rectum and required an abdominoperineal resection. The median tumor size was 4 cm (range: 1.5-6 cm) and the median distance from the anal verge was 4 cm (range: 3-7 cm). The whole pelvis received 46.8 Gy followed by a 3.60 Gy boost to the primary tumor bed. The median follow-up was 43 months (range: 6-82 months).

Full Text Available Background. Acupuncture has been shown to reduce preoperative anxiety in several previous randomized controlled trials (RCTs. In order to assess the preoperative anxiolytic efficacy of acupuncture therapy, this study conducted a meta-analysis of an array of appropriate studies. Methods. Four electronic databases (MEDLINE, EMBASE, CENTRAL, and CINAHL were searched up to February 2014. In the meta-analysis data were included from RCT studies in which groups receiving preoperative acupuncture treatment were compared with control groups receiving a placebo for anxiety. Results. Fourteen publications (N = 1,034 were included. Six publications, using the State-Trait Anxiety Inventory-State (STAI-S, reported that acupuncture interventions led to greater reductions in preoperative anxiety relative to sham acupuncture (mean difference = 5.63, P < .00001, 95% CI [4.14, 7.11]. Further eight publications, employing visual analogue scales (VAS, also indicated significant differences in preoperative anxiety amelioration between acupuncture and sham acupuncture (mean difference = 19.23, P < .00001, 95% CI [16.34, 22.12]. Conclusions. Acupuncture therapy aiming at reducing preoperative anxiety has a statistically significant effect relative to placebo or nontreatment conditions. Well-designed and rigorous studies that employ large sample sizes are necessary to corroborate this finding.

Yokukansan (YKS), a Japanese traditional herbal medicine for neurosis and insomnia, is speculated to be useful for perioperative psychiatric symptoms in cancer patients, but there exists little empirical evidence. This study provides preliminary data about the efficacy, feasibility, and side effects of YKS for the treatment of preoperative anxiety and postoperative delirium in cancer patients. We retrospectively reviewed the medical records of colorectal cancer patients who took YKS for preoperative anxiety, evaluating the following: (1) patient characteristics, (2) feasibility of taking YKS, (3) changes in preoperative anxiety based on the Clinical Global Impression (CGI) scale and Edmonton Symptom Assessment System-revised (ESAS-r-anxiety), (4) incidence of postoperative delirium and (5) YKS-related side effects. We reviewed 19 medical records. There was a significant difference between ESAS-r-anxiety scores (P = 0.028) before and after taking YKS, but no difference between CGI scores (P = 0.056). The incidence of postoperative delirium was 5.2% (95% CI = 0.0-14.5). One patient could not complete the course of YKS during the perioperative administration period, but there were no side effects of Grade 2 or worse according to the Common Terminology Criteria for Adverse Events v4. Cancer patients could safely take YKS before surgery. There was a significant improvement in preoperative anxiety after taking YKS, and the incident rate of postoperative delirium was lower than in previous studies. These results suggest that YKS may be useful for perioperative psychiatric symptoms in cancer patients. Further well-designed studies are needed to substantiate our results. © The Author 2017.

Real-time and volumetric acquisition of X-ray CT, MR, and SPECT is the latest trend of the medical imaging devices. A clinical challenge is to use these multi-modality volumetric information complementary on patient in the entire diagnostic and surgical processes. The intraoperative image and patient integration intents to establish a common reference frame by image in diagnostic and surgical processes. This provides a quantitative measure during surgery, for which we have been relied mostly on doctors' skills and experiences. The intraoperative image and patient integration involves various technologies, however, we think one of the most important elements is the development of markerless registration, which should be efficient and applicable to the preoperative multi-modality data sets, intraoperative image, and patient. We developed a registration system which integrates preoperative multi-modality images, intraoperative video image, and patient. It consists of a real-time registration of video camera for intraoperative use, a markerless surface sampling matching of patient and image, our previous works of markerless multi-modality image registration of X-ray CT, MR, and SPECT, and an image synthesis on video image. We think these techniques can be used in many applications which involve video camera like devices such as video camera, microscope, and image Intensifier. (author)

Noninvasive localization of brain function is used to understand and treat neurological disease, exemplified by pre-operative fMRI mapping prior to neurosurgical intervention. The principal approach for generating these maps relies on brain responses evoked by a task and, despite known limitations, has dominated clinical practice for over 20years. Recently, pre-operative fMRI mapping based on correlations in spontaneous brain activity has been demonstrated, however this approach has its own limitations and has not seen widespread clinical use. Here we show that spontaneous and task-based mapping can be performed together using the same pre-operative fMRI data, provide complimentary information relevant for functional localization, and can be combined to improve identification of eloquent motor cortex. Accuracy, sensitivity, and specificity of our approach are quantified through comparison with electrical cortical stimulation mapping in eight patients with intractable epilepsy. Broad applicability and reproducibility of our approach are demonstrated through prospective replication in an independent dataset of six patients from a different center. In both cohorts and every individual patient, we see a significant improvement in signal to noise and mapping accuracy independent of threshold, quantified using receiver operating characteristic curves. Collectively, our results suggest that modifying the processing of fMRI data to incorporate both task-based and spontaneous activity significantly improves functional localization in pre-operative patients. Because this method requires no additional scan time or modification to conventional pre-operative data acquisition protocols it could have widespread utility. Copyright © 2015.

Bariatric surgery is an effective treatment for patients with type 2 diabetes and refractory obesity; however, many patients have nonoptimal glycemic control preoperatively. We created an interprofessional bariatric glycemic optimization clinic. Patients were seen monthly and received weekly phone calls. We analyzed the effectiveness in assisting patients reach a preoperative glycated hemoglobin (A1C) level of weight was 134.4±29.2 kg. Baseline body mass index was 48.2±8.3 kg/m 2 . Duration of diabetes was 9±7.9 years. Baseline A1C level was 9.0±1.2%. Number of antihyperglycemic agents at baseline was 2.7±0.96. Seventy-five percent reached a target A1C level of ≤7.5%, 92% reached a target of ≤8.0% and 95% reached a target of ≤8.5%; 32% had achieved A1C levels ≤7.5% at 1 month, 59% at 2 months, 70% at 3 months, 73% at 4 months and 75% at 5 months. Mean number of antihyperglycemic agents at target A1C levels was 3.6±1.1. Mean absolute decrease in A1C levels from baseline to target A1C levels was 1.7±1.2. Mean absolute change in weight was -1.9±8.0 kg. Percent change in body weight from baseline to target A1C level was -1.3±4.9%. Glycemic optimization for candidates with diabetes for bariatric surgery is possible in a short time by an interprofessional diabetes team and without weight gain. Further research is needed to determine whether better preoperative glycemic control improves bariatric surgery outcomes. Copyright © 2018. Published by Elsevier Inc.

Oligometastasis is defined as a transitional state between localized and widespread systemic metastatic cancers. In colorectal cancer, the prognostic factors and prognostic value of preoperative serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) for patients with colorectal liver oligometastases (CLOM) undergoing hepatic resection have not been well explored. Therefore, the present study included 141 patients with CLOM (≤5 liver metastases) who underwent R0 resection from 2005 to 2012. The association of clinicopathological factors including preoperative CA19-9 and CEA levels with overall survival (OS) was analyzed with univariate and multivariate analyses. Kaplan-Meier analysis showed that patients with high CA19-9 levels tended to have poorer OS than those with low levels (median OS 21.5 vs. 64.0 months, P = 0.002). Preoperative CEA levels were not significantly associated with OS (P > 0.05). Univariate and multivariate analyses demonstrated that larger tumor size of liver metastases (HR 1.911; 95 % CI 1.172-3.114; P = 0.009), bilobar distribution (HR 1.776; 95 % CI 1.097-2.873; P = 0.019), and higher preoperative CA19-9 levels (HR 1.954; 95 % CI 1.177-3.242; P = 0.010) were independent predictors of poor OS for patients with CLOM. Our study identified tumor size, distribution, and preoperative CA19-9 levels as independent prognostic factors for OS of patients with CLOM. In particular, measurement of preoperative CA19-9 levels offers an easy tool that could help identify high-risk patients and aid in improving the management of patients with CLOM.

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.

Background: The prognostic role of restaging rectal magnetic resonance imaging (MRI) in patients with preoperative CRT has not been established. The goal of this study was to evaluate the diagnostic accuracy and prognostic role of radiological staging by rectal MRI after preoperative chemoradiation (CRT) in patients with rectal cancer. Methods: A total of 231 consecutive patients with rectal cancer who underwent preoperative CRT and radical resection from January 2008 to December 2009 were prospectively enrolled. The diagnostic accuracy and prognostic significance of post-CRT radiological staging by MRI was evaluated. Results: The sensitivity, specificity, positive predictive value, and negative predictive value of radiological diagnosis of good responders (ypTNM stage 0–I) were 32%, 90%, 65%, and 69%, respectively. The overall accuracy of MRI restating for good responders was 68%. The 5-year disease-free survival rates of patients with radiological and pathological TNM stage 0, stage I, and stage II–III were 100%, 94%, and 76%, respectively (P = 0.037), and 97%, 87%, and 73%, respectively (P = 0.007). On multivariate analysis, post-CRT radiological staging by MRI was an independent prognostic factor for disease-free survival. Conclusion: Radiological staging by MRI after preoperative CRT may be an independent predictor of survival in patients with rectal cancer

Preoperative fasting is an established procedure to be practiced for patients before surgery, but optimal preoperative fasting time still remains controversial. The aim of this study was to investigate the effect of "shortened preoperative fasting time" on the change in the amount of total body water (TBW) in elective surgical patients. TBW was measured by multi-frequency impedance method. The patients, who were scheduled to undergo surgery for stomach cancer, were divided into two groups of 15 patients each. Before surgery, patients in the control group were managed with conventional preoperative fasting time, while patients in the "enhanced recovery after surgery (ERAS)" group were managed with "shortened preoperative fasting time" and "reduced laxative medication." TBW was measured on the day before surgery and the day of surgery before entering the operating room. Defecation times and anesthesia-related vomiting and aspiration were monitored. TBW values on the day of surgery showed changes in both groups as compared with those on the day before surgery, but the rate of change was smaller in the ERAS group than in the control group (2.4±6.8% [12 patients] vs. -10.6±4.6% [14 patients], pfasting time" and "reduced administration of laxatives" is effective in the maintenance of TBW in elective surgical patients.

We assessed the prognostic significance of preoperative serum carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 242 (CA242) levels in surgically treated colorectal cancer patients. The relationship of preoperative serum CEA, CA19-9 and CA242 levels with disease characteristics was investigated in 310 patients. Correlation between tumor markers was investigated using Pearson correlation test. Univariate and multivariate survival analyses were used to study the relationship between preoperative tumor markers and prognosis [disease free survival (DFS) and overall survival (OS)]. Kaplan-Meier analysis with log rank test was used to assess the impact of tumor marker levels on survival. Positive rate of preoperative serum CEA, CA19-9 and CA242 were 54.84%, 47.42% and 37.10%, respectively. High preoperative CEA level was associated with tumor size (P = 0.038), T stage (P tumor AJCC stage (P = 0.023). Preoperative CA242 positively correlated with CEA (P markers was of independent prognostic value in CRC (HR = 2.532, 95% CI: 1.400-4.579, P = 0.002 for OS; and HR = 2.366, 95% CI: 1.334-4.196, P = 0.003 for DFS). Combined detection of preoperative serum CEA, CA19-9 and CA242 is of independent prognostic value for management of CRC patients treated surgically.

A retrospective study of 44 patients with rectal cancer who received preoperative radiation (42.6 Gy) combined with chemotherapy and 37 who received resection alone (control group) was undertaken to evaluate the effect of preoperative radiation therapy on local recurrence of rectal cancer. The rate of local recurrence in the radiation group was reduced to 4.5% compared with that in the controls (18.9%). From a pathological point of view, factors that have a close association with recurrence, such as depth of invasion, ew (defined as the distance between the external surgical surface and the deepest site of invasion) and lymph nodal involvement, have been successfully changed after radiation therapy. It was also evident that the rate of recurrence in irradiated patients, depth of invasion of a 2 (defined as the invasion of cancer far beyond the muscle layer but without involvement of other organs) or ew less than 2 mm was significantly lower than in patients with the same pathological conditions in whom radiation was not used. However, especially in patients with remote lymph node metastasis, there was no difference in local recurrence rate between the two groups. From these findings, it was concluded that a careful follow up is necessary for patients with remote lymph node involvement even after radiation therapy. (author)

To evaluate safety and efficacy of preoperative administration of enteral nutrition support in gastric cancer patients at risk of malnutrition. A single center randomized controlled clinical trial was performed in 60 gastric cancer patients in West China Hospital from May to October 2012. Thirty patients were given enteral nutrition support(Ensure(R)) manufactured by Abbott Laboratories for ten consecutive days before surgical operation in the treatment group, and 30 patients were given an isocaloric and isonitrogenous homogenized diet in the control group for 10 days as well. The laboratory parameters of nutritional status and hepatorenal function were observed and compared between the two groups on admission, preoperative day 1 and postoperative day 3, respectively. Clinical observations, such as nausea and vomiting, were carried out until patients were discharged. Before the intervention, there were no significant differences in the baseline characteristics between the two groups. The levels of serum albumin [(33.9±5.6) g/L vs. (31.0±5.3) g/L, P0.05). Moreover, two patients with nausea and one with vomiting in each group were found. In clinical observation period, no severe treatment-related adverse event were observed. The enteral supplement with Ensure(R) in gastric cancer patients at risk of malnutrition during preoperative period is effective and safe, which is superior to homogenized diet and an appropriate choice for gastric cancer patients with nutritional risk.

Primary hyperparathyroidism (PHP) is a common endocrine disease, and its most effective treatment is surgery. Postoperative hypocalcemia is a morbidity of parathyroid surgeries, and it may extend hospitalization durations. The purpose of this study is to determine the predictive factors related to the development of hypocalcemia and hungry bone syndrome (HBS) in patients who underwent parathyroidectomy for PHP. Laboratory data comprising parathyroid hormone (PTH), calcium, phosphate, 25-OHD, albumin, magnesium, alkaline phosphatase (ALP), blood urea nitrogen (BUN), and thyroid stimulating hormone (TSH) of the patients were recorded preoperatively, on the 1st and 4th days postoperatively, and in the 6th postoperative month, and their neck ultrasound (US) and bone densitometry data were also recorded. Hypocalcemia was seen in 63 patients (38.4%) on the 1st day after parathyroidectomy. Ten patients (6.1%) had permanent hypocalcemia in the 6th month after surgery. Out of the patients who underwent parathyroidectomy for PHP, 22 (13.4%) had HBS. The incidence of postoperative hypocalcemia was higher in patients who underwent parathyroidectomy for PHP, who had parathyroid hyperplasia, and who had osteoporosis. Preoperative PTH, ALP, and BUN values were higher in those patients who developed HBS. Furthermore, HBS was more common in patients who had osteoporosis, who had parathyroid hyperplasia, and who underwent thyroidectomy simultaneously with parathyroidectomy. As a result, patients who have the risk factors for development of hypocalcemia and HBS should be monitored more attentively during the perioperative period.

Full Text Available OBJECTIVE: The aim of this paper was to compare the efficacy and safety of S-1-based and capecitabine-based preoperative chemoradiotherapy regimens in patients with locally advanced rectal cancer through a retrospective matched-pair analysis. MATERIALS AND METHODS: Between Jan 2010 and Mar 2014, 24 patients with locally advanced rectal cancer who received preoperative radiotherapy concurrently with S-1 were individually matched with 24 contemporary patients with locally advanced rectal cancer who received preoperative radiotherapy concurrently with capecitabine according to clinical stage (as determined by pelvic magnetic resonance imaging and computed tomography and age (within five years. All these patients performed mesorectal excision 4-8 weeks after the completion of chemoradiotherapy. RESULTS: The tumor volume reduction rates were 55.9±15.1% in the S-1 group and 53.8±16.0% in the capecitabine group (p = 0.619. The overall downstaging, including both T downstaging and N downstaging, occurred in 83.3% of the S-1 group and 70.8% of the capecitabine group (p = 0.508. The significant tumor regression, including regression grade I and II, occurred in 33.3% of S-1 patients and 25.0% of capecitabine patients (p = 0.754. In the two groups, Grade 4 adverse events were not observed and Grade 3 consisted of only two cases of diarrhea, and no patient suffered hematologic adverse event of Grade 2 or higher. However, the incidence of diarrhea (62.5% vs 33.3%, p = 0.014 and hand-foot syndrome (29.2% vs 0%, p = 0.016 were higher in capecitabine group. Other adverse events did not differ significantly between two groups. CONCLUSIONS: The two preoperative chemoradiotherapy regimens were effective and safe for patients of locally advanced rectal cancer, but regimen with S-1 exhibited a lower incidence of adverse events.

Background. The optimal care for patients with unresectable, non-metastatic pancreatic adenocarcinoma (PAC) is debated. We treated 17 consecutive cases with preoperative radiochemotherapy (RCT) as a means for downstaging their tumours and compared outcome with 35 patients undergoing direct surgery for primarily resectable PAC during the same time period. Methods. The patients had biopsy proven, unresectable, non-metastatic PAC which engaged ≥ 50% of the circumference of a patent mesenteric/portal vein for a distance ≥ 2 cm and/or 2 d1; capecitabine 2 000 mg/m 2 d1-14 q 3 w) followed by 3-D conformal radiotherapy (50.4 Gy; 1.8 Gy fractions) with reduced Xelox (d1-5 q 1 w X 6). Results. No incident of RCT-related CTC Grade 3-4 haematologic and six cases of non-haematologic side-effects were diagnosed. Sixteen patients completed the RCT and were rescanned with CT and reevaluated for surgery 4 weeks post-RCT. Five cases were diagnosed with new metastases to the liver. Eleven patients were accepted for surgery whereof eight underwent a curative R 0 -resection. The median overall survival for the latter group was 29 months, which compared favourably with our control group of patients undergoing direct curative surgery for primarily resectable PAC (median OS: 16 months; RO-rate: 75%). Perioperative morbidity was similar in the two cohorts but the duration of surgery was longer (576 vs. 477 min) and the op blood loss was greater (3288 vs. 1460 ml) in the RCT-cohort (p < 0.05). The 30-day mortality was zero in both groups. Conclusion. Preoperative RCT in patients with locally advanced PAC resulted in a high rate of curative resections and promising median survival in our treatment series. This trimodality approach merits further exploration in new studies, which are currently underway at our Dept

Purpose: The existing randomized evidence has failed to conclusively demonstrate the benefit or otherwise of preoperative radiotherapy in treating patients with potentially resectable esophageal carcinoma. This meta-analysis aimed to assess whether there is benefit from adding radiotherapy prior to surgery. Methods and Materials: This quantitative meta-analysis included updated individual patient data from all properly randomized trials (published or unpublished) comprising 1147 patients (971 deaths) from five randomized trials. Results: With a median follow-up of 9 years, the hazard ratio (HR) of 0.89 (95% CI 0.78-1.01) suggests an overall reduction in the risk of death of 11% and an absolute survival benefit of 3% at 2 years and 4% at 5 years. This result is not conventionally statistically significant (p 0.062). No clear differences in the size of the effect by sex, age, or tumor location were apparent. Conclusion: Based on existing trials, there was no clear evidence that preoperative radiotherapy improves the survival of patients with potentially resectable esophageal cancer. These results indicate that if such preoperative radiotherapy regimens do improve survival, then the effect is likely to be modest with an absolute improvement in survival of around 3 to 4%. Trials or a meta-analysis of around 2000 patients would be needed to reliably detect such an improvement (15→20%)

Vascular calcifications on the preoperative radiograph of patients scheduled for total knee arthroplasty (TKA) often give rise to concern, as their clinical relevance remains uncertain. The aim of this study was to investigate whether these vascular calcifications - especially medial artery calcifications (MACs), which increase arterial stiffness - were associated with tourniquet failure and thus with increased intraoperative blood loss. A total of 765 patients who underwent primary TKA with a tourniquet (cuff pressure 350 mmHg) between 2009 and 2011 were screened for vascular calcifications on the preoperative radiograph. Vascular calcifications were classified into intimal and medial artery calcifications. Intraoperative blood loss of patients with and without MAC was compared, and a mixed linear regression model was used to adjust for the presence of several confounding factors (e.g., obesity, operating time). None of the 50 (6.5%) patients with MAC showed signs of tourniquet failure. Intraoperative blood loss of patients with MAC was not significantly elevated compared to the overall study group (p = 0.592) even when corrected for the presence of several confounding factors. We found no evidence that vascular calcifications seen on the preoperative radiograph might be associated with tourniquet failure. However, surgeons should be aware of this possibility as tourniquet failure might become more common considering the ongoing trend toward minimizing cuff pressures. (orig.)

To determine whether preoperative CT is helpful in predicting the development of recurrent tumor following surgical resection in patients with esophageal cancer. Thirty patients with esophageal cancer in whom preoperative CT of the chest had been performed were included in the study. All had undergone esophagectomy, esophagogastrostomy and lymph node dissection at our institution between 1995 and 1997. They were divided into two groups according to the development of tumor recurrence during the follow-up period of three years. Sixteen patients (group I) suffered tumor recurrence, while the other 14 (group II) remained tumor-free after surgery. In each group, a review of the preoperative CT scans indicated the length, thickness, location and margin of the tumor, and the presence or absence of lymphadenopathy in the mediastinum and/or upper abdomen. Differences in preoperative CT findings between the two groups were assessed by statistical testing. Lymphadenopathy of the mediastinum and/or upper abdomen was seen in 11 (69%) of 16 patients in group I and three (21%) of 14 in group II (p .05). In group I, five esophageal tumors were located in the middle esophagus and eleven in the lower esophagus. In group II, such tumor was located one in the upper esophagus, six in the middle esophagus, and seven in the lower esophagus (p>.05). Patients with preoperative CT findings of lymphadenopathy and/or and indistinct primary tumor margin are more likely to develop tumor recurrence following surgical resection than those without these findings

Preoperative lung cancer with mediastinal lymph nodes metastasis can be diagnosed by vedio mediastinoscopy (VM) and CT. This study was to explore the value of VM and CT in the diagnosis of N staging of preoperative lung cancer, and to discuss the difference between the two methods. Forty-eight cases diagnosed of lung cancer by CT or PET-CT were examined by VM. The sensitivity, specificity, validity, positive predictive value and negative predictive value of VM and CT were speculated according to the postoperative pathological reports, and the difference between VM and CT in the diagnosis of lung cancer with mediastinal lymph nodes metastasis was discussed. (1)Under the examination of VM, 31 patients with the negative outcome received the direct operation; 14 patients with N2 received 2 courses of neoadjuvant chemotherapy before operation; 3 patients with N3 received chemotherapy and/or radiotherapy. (2)Forty-one cases with final diagnosis of lung cancer were used as samples to speculate the sensitivity, specificity, validity, positive predictive value and negative predictive value of VM. They were 93.3%, 100%, 97.6%, 100%, 96.3%, which of CT were 66.7%, 53.8%, 58.5%, 45.5%, 73.7% (Chi-square=4.083, P=0.039), the difference between VM and CT was statistically significant. (3)In this group, the complications of VM incidence rate was 2.08% (1/48), and the case was pneumothorax. VM is superior to CT in the diagnosis of N staging of preoperative lung cancer; Due to its safety and effectiveness, VM will be wildly used in the field of thoracic surgery.

From January 1976, 50 patients with squamous cell cancer of the head and neck were treated with telecobalt preoperative irradiation followed by appropriate surgery. Another group of 50 patients, who matched in risk factors and stage of disease, were treated with preoperative chemotherapy and surgery. Chemotherapy consisted of bleomycin, vincristine, mitolactol and methotrexate. All patients received 3 courses. Surgery was performed 2-3 weeks post-chemotherapy or 4-6 weeks post-radiotherapy. Forty four percent of the patients in the radiotherapy group showed recurrences, while 30% of the patients had recurrence in the chemotherapy group. The overall 3-year survival rate was 66% in the chemotherapy group and 57% in the radiation therapy group, with no statistical difference. (author)

The techniques and applications of 3-dimensional (3D) printing have progressed at a fast pace. In the last 10 years, there has been significant progress in applying this technology to medical applications. We present a case of osteogenesis imperfecta in which treatment was aided by prospectively using patient-specific, anatomically accurate 3D prints of the calvaria. The patient-specific, anatomically accurate 3D prints were used in the clinic and in the operating room to augment patient education, improve surgical decision making, and enhance preoperative planning. A 41-year-old woman with osteogenesis imperfecta and an extensive neurosurgical history presented for cranioplasty revision. Computed tomography (CT) data obtained as part of routine preoperative imaging were processed into a 3D model. The 3D patient-specific models were used in the clinic for patient education and in the operating room for preoperative visualization, planning, and intraoperative evaluation of anatomy. The patient reported the 3D models improved her understanding and comfort with the planned surgery when compared with discussing the procedure with the neurosurgeon or viewing the CT images with a neuroradiologist. The neurosurgeon reported an improved understanding of the patient's anatomy and potential cause of patient symptoms as well as improved preoperative planning compared with viewing the CT imaging alone. The neurosurgeon also reported an improvement in the planned surgical approach with a better intraoperative visualization and confirmation of the regions of planned calvarial resection. The use of patient-specific, anatomically accurate 3D prints may improve patient education, surgeon understanding and visualization, preoperative decision making, and intraoperative management.

AIM: The purpose of this study was to analyse the results of preoperative short course radiotherapy in a consecutive, national cohort of patients with rectal cancer. METHODS: Through a validated, prospective national database we identified 520 Danish patients who presented with high-risk mobile...... tumours in the lower two thirds of the rectum and were referred for preoperative radiotherapy with 5 x 5 Gy. The inclusion period was 56 months. Radiotherapy data was retrospectively collected. RESULTS: Of the 520 patients, 514 completed radiotherapy and 506 had surgery. Surgery was considered curative...... in 439 patients. The 3-year local recurrence rate was 4.0% (95% CI 2.5-6.5%) and the distant recurrence rate at 3 years was 18.7% (95% CI 15.4-22.5%). The 5-year disease free survival rate was 40.2% (95% CI 27.0-53.1%) and overall survival 50.4% (95% CI 36.1-63.1%). Most tumours (61%) were classified...

The purpose of this study was to determine effect of three different types of music on patients' preoperative anxiety. This randomized controlled trial included 180 patients who were randomly divided into four groups. While the control group didn't listen to music, the experimental groups respectively listened to natural sounds, Classical Turkish or Western Music for 30 min. The State Anxiety Inventory (STAI-S), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and cortisol levels were checked. The post-music STAI-S, SBP, DBP, HR and cortisol levels of the patients in music groups were significantly lower than pre-music time. All types of music decreased STAI-S, SBP, and cortisol levels; additionally natural sounds reduced DBP; Classical Turkish Music also decreased DBP, and HR. All types of music had an effect on reducing patients' preoperative anxiety, and listening to Classical Turkish Music was particularly the most effective one. Copyright © 2018 Elsevier Ltd.

Preoperative computed tomography and scintigraphy to facilitate the detection of accessory spleen in patients with hematologic disorders

International Nuclear Information System (INIS)

Koyanagi, Nobuhiro; Kanematsu, Takashi; Sugimachi, Keizo

1988-01-01

Accessory spleens of 1.5 cm in size were preoperatively identified by the combined use of computerized tomography and splenic scintigraphy in two patients with hematologic diseases. After the accessory spleen had been removed from the first patient, who had persistent hereditary spherocytosis and had undergone a splenectomy 15 months before, a postoperative decrease in hyperbilirubinemia was noted. In the other patient who had idiopathic thrombocytopenic purpura, a successful accessory splenectomy was done at the same time as her splenectomy, and was followed by 6 months' complete remission. These events indicate that preoperative investigations using computerized tomography and scintigraphy are indispensable for ruling out an accessory spleen in those patients for whom splenectomy needs to be done in order to alleviate hematologic disorders.

This study was conducted to provide information regarding prevalence of pain, type of provider managing pain, and use of Internet for information regarding pain, among patients coming for presurgical anesthesia consultation at a major academic institution. With IRB approval, patients were invited to participate in a voluntary and anonymous 14 question survey given to them when they presented for anesthesia consultation prior to their surgical procedure. The qualitative/categorical data were summarized by number (percentage [%]) and analyzed by Chi-square test or Fisher's exact test as appropriate. All data analyses were performed using the statistical software SAS, v9.2. A total of 1039 patients were asked to complete the survey and 670 patients returned their responses (response rate = 64.5%). 83% of patients had a history of prior surgery. 57% were concerned about postoperative pain. 30% of patients had chronic pain for more than 3 months pre-operatively. 16% of patients had looked online for information regarding pain. Pain physicians were involved in pain management only in 3.8% of these patients. Patients are presenting for surgery with significant pre-operative pain issues. Knowing this information pre-operatively will help healthcare personnel manage postsurgical pain more effectively. Patients are also using the Internet to obtain information regarding pain. As providers, there may be value to directing patients to reliable information online during consultation. As all physicians will eventually be managing chronic pain in their patients, pain education should be given priority in medical school curriculum. © 2013 World Institute of Pain.

Background and purpose: preoperative radiochemotherapy has been reported to enhance tumor response and to improve long-term survival in advanced squamous cell carcinoma of the head and neck. This retrospective study evaluates regression rate and long-term survival in 228 patients with primary oral squamous cell carcinoma treated by neoadjuvant radiochemotherapy and radical surgery. Patients and methods: all patients with biopsy-proven, resectable oral squamous cell carcinoma - TNM stages II-IV without distant metastasis - received preoperative treatment consisting of fractioned irradiation of the primary and the regional lymph nodes with a total dose of 40 Gy and additional cisplatin (n = 160) or carboplatin (n = 68) during the 1st week of treatment. Radical surgery and neck dissection followed after a delay of 10-14 days. The study only included cases with histologically negative resection margins. Results: after a median follow-up of 5.2 years, 53 patients (23.2%) had experienced local-regional recurrence. The median 2-year disease-specific survival (DSS) rate was 86.2%. 5-year DSS and 10-year DSS were 76.3% and 66.7%, respectively. Complete histological local tumor regression after surgery (ypTO) was observed in 50 patients (21.9%) and was independent of pretreatment tumor classification. Uni- and multivariate survival analysis revealed that ypT- and ypN-stage were the most decisive predictors for DSS. Conclusion: preoperative radiochemotherapy with cisplatin/carboplatin followed by radical surgery attains favorable long-term survival rates. This applies especially to cases with complete histological tumor regression after radiochemotherapy, which can be assumed for one of five patients. (orig.)

Though the mandibular swing, as an approach to certain upper aerodigestive tract malignancies, has been gaining popularity in recent years, there has been little reported as to the feasibility of this procedure in subjects who have received radical preoperative radiotherapy. We have recently reported the results of 23 such patients, and we now present an update. The results presented are of a retrospective analysis of 44 patients, 50% of whom received radical preoperative radiotherapy to fields including the osteotomy site. As in the previous study, there were no statistically significant differences between the complication rates in the irradiated and nonirradiated patient populations. All the patients were orally rehabilitated

Purpose/Objectives: A prospective study for localized esophageal cancer using hyperfractionated radiotherapy(1.2Gy/fx, BID, 48Gy/4wks) with concurrent chemotherapy FP(CDDP 60mg/M 2 /d, d1 and d29, 5-FU 1gm/M 2 /d, continuous infusion d2-6 and d30-34) followed by esophagectomy has been conducted to evaluate the efficacy and toxicity of chemoradiation followed by surgery and curative potential of transhiatal esophagecomy. We analyze the clinical/pathological response and toxicity of preoperative regimen and report the patterns of failure and the survival of patients in esophagectomy group compared with patients who treated with definitive radiotherapy. Materials and Methods: Since May 1993, 48 patients with localized esophageal cancer entered on this trial and 42 patients were evaluated for response and toxicity in 4 weeks after completion of preoperative regimen. 15 patients underwent surgery and 5 are waiting for surgery. Among 22 patients who refused the surgery, 11 patients received the definitive radiotherapy (≥60Gy) and 11 of them refused further therapy. In 41 men and 1 women with median age of 61 years old (range 41-75 years), 8 patients were staged as SI, 22 SII, and 12 SIII with endoscopic, histologic and radiologic evaluation. Results: Clinical tumor response was observed in 79%((33(42))) and 66%((23(35))) of patients who had histologic evaluation showed complete pathologic response. (13(15)) who underwent surgery achieved complete resection and surgical specimen of 7(47%) patients showed no histologic evidence of disease. 20% ((3(15))) surgical mortality was observed. Among 15 patients who underwent surgery, 53% ((8(15))) are alive NED in 3-19 months (median 7 months), 1 patient is alive with disease in 3 months, 2 patients died of progression, 3 postoperative mortality and 1 patient died of lung cancer in 5 months. Among 11 patients who received curative radiotherapy, 6 are alive with good performance, NED in 9-15 months (median 10 months), 3 are alive

Worldwide, esophageal cancer ranks fifth in the mortality rate regarding tumor locations. EUS is an essential tool in the evaluation of these patients allowing accurate staging and permitting stratified treatment options. AIM. We have studied prospectively the impact of EUS in the evaluation and decision for therapy of patients with esophageal cancer diagnosed in our center. From March 2001 through March 2006, 220 patients were hospitalized at the Center of Gastroenterology and Hepatology, Fundeni Clinical Institute, with the diagnosis of esophageal cancer. Out of the 220 patients, 41 patients, with no major comorbidities contraindicating esophagectomy already having been screened by abdominal and thoracic CT to disclose distant metastases, had EUS with the definite purpose of staging esophageal carcinoma and selecting adequate therapy. Assuming that without preoperative staging by EUS, all 41 patients in the study group would have been offered surgical treatment, we evaluated the number of patients and the modality in which EUS resulted in changes to the therapeutic plan. Depth of invasion was recorded for the 41 patients as follows: T1 in 2 patients (4.9%), T2 in 6 patients (14.6%), T3 in 24 patients (58.5%), and T4 in 10 patients (22%). Regional lymph node (N) status as determined by EUS criteria was as follows: N0 in 7 patients (17%) and N1 in 34 patients (83%). Assessment of distant metastases (M) was recorded showing 4 patients with celiac axis lymph nodes metastases (M1). Preoperative EUS staging changed the decision for surgery in 18 of 41 patients (44%) (p<0.0001) and allowed primary esophagectomy in only 6 patients (15%) (p<0.0001). Compared to histopathology, the overall accuracy of EUS staging for pT1 and pT2 was 80% for staging pT3 and pT4 77% and for lymph node evaluation was approximately 75%. Esophageal EUS offers useful information to clinicians caring for patients with esophageal cancer, impacts clinical decision making, and should be used in

Purpose: Preoperative chemoradiotherapy (CRT) is superior to radiotherapy (RT) in locally advanced rectal cancer, but the survival gain is limited. Late toxicity is, therefore, important. The aim was to compare late bowel, urinary, and sexual functions after CRT or RT. Methods and Materials: Patients (N = 207) with nonresectable rectal cancer were randomized to preoperative CRT or RT (2 Gy Multiplication-Sign 25 {+-} 5-fluorouracil/leucovorin). Extended surgery was often required. Self-reported late toxicity was scored according to the LENT SOMA criteria in a structured telephone interview and with questionnaires European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30), International Index of Erectile Function (IIEF), and sexual function -vaginal changes questionnaire (SVQ). Results: Of the 105 patients alive in Norway and Sweden after 4 to 12 years of follow-up, 78 (74%) responded. More patients in the CRT group had received a stoma (73% vs. 52%, p = 0.09). Most patients without a stoma (7 of 12 in CRT group and 9 of 16 in RT group) had incontinence for liquid stools or gas. No stoma and good anal function were seen in 5 patients (11%) in the CRT group and in 11 (30%) in the RT group (p = 0.046). Of 44 patients in the CRT group, 12 (28%) had had bowel obstruction compared with 5 of 33 (15%) in the RT group (p = 0.27). One-quarter of the patients reported urinary incontinence. The majority of men had severe erectile dysfunction. Few women reported sexual activity during the previous month. However, the majority did not have concerns about their sex life. Conclusions: Fecal incontinence and erectile dysfunction are frequent after combined treatment for locally advanced rectal cancer. There was a clear tendency for the problems to be more common after CRT than after RT.

The objective of this prospective study was to evaluate the relationship between the circulating lymphocyte subpopulation counts during preoperative chemoradiotherapy (CRT) and tumor response in locally advanced rectal cancer. From August 2015 to June 2016, 10 patients treated with preoperative CRT followed by surgery were enrolled. Patients received conventional fractionated radiotherapy (50.4 Gy) with fluorouracil-based chemotherapy. Surgical resection was performed at 4 to 8 weeks after the completion of preoperative CRT. The absolute blood lymphocyte subpopulation was obtained prior to and after 4 weeks of CRT. We analyzed the association between a tumor response and change in the lymphocyte subpopulation during CRT. Among 10 patients, 2 (20%) had evidence of pathologic complete response. In 8 patients with clinically node positive, 4 (50%) had nodal tumor response. All lymphocyte subpopulation counts at 4 weeks after CRT were significantly lower than those observed during pretreatment (p < 0.01). A high decrease in natural killer (NK) cell, count during CRT (baseline cell count - cell count at 4 weeks) was associated with node down staging (p = 0.034). Our results suggest that the change of lymphocyte subset to preoperative CRT may be a predictive factor for tumor response in rectal cancer.

The primary purpose of this study was to determine the effect of the preoperative position of the musculotendinous junction (MTJ) on rotator cuff healing after double-row arthroscopic rotator cuff repair. A secondary purpose was to evaluate how tendon length and MTJ position change when the rotator cuff heals. Preoperative and postoperative magnetic resonance imaging (MRI) scans of 42 patients undergoing arthroscopic double-row rotator cuff repair were reviewed. Patients undergoing repairs with other constructs or receiving augmented repairs (platelet-rich fibrin matrix) who had postoperative MRI scans were excluded. Preoperative MRI scans were evaluated for anteroposterior tear size, tendon retraction, tendon length, muscle quality, and MTJ position with respect to the glenoid in the coronal plane. The position of the MTJ was referenced off the glenoid face as either lateral or medial. Postoperative MRI scans were evaluated for healing, tendon length, and MTJ position. Of 42 tears, 36 (86%) healed, with 27 of 31 small to medium tears (87%) and 9 of 11 large to massive tears (82%) healing. Healing occurred in 94% of tears that had a preoperative MTJ lateral to the face of the glenoid but only 56% of tears that had a preoperative MTJ medial to the glenoid face (P = .0135). The measured tendon length increased an average of 14.4 mm in patients whose tears healed compared with shortening by 6.4 mm in patients with tears that did not heal (P rotator cuff repair. The position of the MTJ with respect to the glenoid face is a reliable, identifiable marker on MRI scans that can be predictive of healing.

Knee osteoarthritis (OA) is a leading cause of disability in older adults (≥60) in the UK. If nonsurgical management fails and if OA severity becomes too great, knee arthroplasty is a preferred treatment choice. Preoperative physiotherapy is often offered as part of rehabilitation to improve postoperative patient-based outcomes. Systematically review whether preoperative physiotherapy improves postoperative, patient-based outcomes in older adults who have undergone total knee arthroplasty (TKA) and compare study interventions to best-practice guidelines. A literature search of Randomized Controlled Trials (RCTs), published April 2004-April 2014, was performed across six databases. Individual studies were evaluated for quality using the PEDro Scale. Ten RCTs met the full inclusion/exclusion criteria. RCTs compared control groups versus: preoperative exercise (n = 5); combined exercise and education (n = 2); combined exercise and acupuncture (n = 1); neuromuscular electrical stimulation (NMES; n = 1); and acupuncture versus exercise (n = 1). RCTs recorded many patient-based outcomes including knee strength, ambulation, and pain. Minimal evidence is presented that preoperative physiotherapy is more effective than no physiotherapy or usual care. PEDro Scale and critical appraisal highlighted substantial methodological quality issues within the RCTs. There is insufficient quality evidence to support the efficacy of preoperative physiotherapy in older adults who undergo total knee arthroplasty.

Despite the recent changes in the treatment of the axilla in selected breast cancer patient, positive sentinel lymph node (SLN) in patients undergoing mastectomy still necessitates axillary lymph node dissection (ALND). In invasive lobular carcinoma (ILC), pre-operative detection of the lymph node metastasis may be demanding due to its unique morphology. The aim of this study was to examine the benefit of preoperative axillary ultrasound (AUS), ultrasound-guided fine-needle aspiration biopsy (US-FNAB), and intra-operative imprint cytology (IIC), in order to avoid two-stage axillary surgery in patients with ILC undergoing mastectomy. The object of this study were 102 patients (median age 52, range 34-73 years) with clinically non-suspicious axilla in whom 108 mastectomies were performed after a pre-operative AUS investigation. Whenever a metastasis was detected in a sentinel lymph node, ALND was done. Reports of the pre-operative AUS investigation, US-FNAB, and IIC were compared with definitive histopathological reports of surgical specimens. In 46 cases lymph node metastases were diagnosed. AUS suspicious lymph nodes were found in 29/108 cases and histopathology confirmed metastases in 22/30 cases. US-FNAB was performed in 29 cases with AUS suspicious lymph nodes. Cytology proved metastases in 11/29 cases. Histopathology confirmed metastases in 10/11 cases with only isolated tumor cells found in one case. IIC investigation was performed in 63 cases and in 10/27 cases metastases were confirmed by histopathology. Pre-operative AUS, US-FNAB, and/or IIC investigation enabled ALND during a single surgical procedure in 20/46 patients with metastases in lymph nodes. Pre-operative AUS, US-FNAB, and/or IIC are/is beneficial in patients with ILC planned for mastectomy in order to decrease the number of two stage axillary procedures.

Objective: To assess the value of preoperative blood oxygen level dependent (BOLD) 3 T functional magnetic resonance imaging (fMRI) to identify motor cortical areas in neurosurgical treatment of intraoperative electrical stimulation for gliomas involving motor areas. Methods: The study included 26 consecutive preoperative BOLD-fMRI sessions in patients with brain gliomas in or near senorimotor cortices. The bilateral hand movement fMRI paradigm was preformed in all patients. The BOLD data were analyzed by the workstation (Leonardo Syngo 2003A, Siemens)to obtain the BOLD-fMRI images, which were used to guide the preoperative neurosurgical planning. With guidance of preoperative mapping, all patients received microsurgery under anaesthesia retaining consciousness using intraoperative motor functional brain mapping with the method of direct electrical stimulations. The brain lesions were removed as far as possible in the case of eloquent areas preservation. The preoperative and postoperative KPS of all patients were operated to evaluate the state of patients. Results: The preoperative mappings of the hand area on primary sensorimotor cortex using BOLD-fMRI were obtained successfully in twenty-three of twenty-six patients. Under anaesthesia retaining consciousness, the primary motor area was monitored by the method of direct electrical stimulations with the guidance of preoperative BOLD-fMRI. There was good correlation between preoperative fMRI findings and intraoperative cortical stimulation. Furthermore, the preoperative mappings could make up for the un-monitored areas during operative cortical stimulation. For the 21 patients of the pre-KPS from 80.0 to 90.0, the pre-KPS and post-KPS are 85.7 and 95.2 respectively, and for the 5 patients of the pre-KPS from 40. 0 to 70.0, the pre-KPS and post-KPS are 68.0 and 90.0 respectively. Conclusion: The preoperative mapping of the hand area on primary sensorimotor cortex using BOLD-fMRI could non-invasively localize the

PurposeSurgical esophagectomy is the gold standard treatment of early-stage esophageal cancer. The procedure is complicated with significant morbidity; the most severe complication being the anastomotic leakage. Anastomotic fistulas are reported in 5–25% of cases and are mainly due to gastric transplant ischemia. Here, we report our experience of ischemic pre-conditioning using preoperative arterial embolization (PreopAE) before esophagectomy.Materials and MethodsThe medical records of all patients who underwent oncologic esophagectomy from 2008 to 2015 were retrospectively reviewed. Patients were divided into two groups: patients who received PreopAE, and a control group of patients who did not benefit from ischemic pre-conditioning. The target arteries selected for PreopAE were the splenic artery, left gastric artery, and right gastric artery. Evaluation of the results was based on anastomotic leakage, postoperative mortality, technical success of PreopAE, and complications related to the embolization procedure.ResultsForty-six patients underwent oncologic esophagectomy with PreopAE and 13 patients did not receive ischemic conditioning before surgery. Thirty-eight PreopAE were successfully performed (83%), but right gastric artery embolization failed for 8 patients. Anastomotic leakage occurred in 6 PreopAE patients (13%) and in 6 patients (46%) in the control group (p = 0.02). The mortality rate was 2% in the PreopAE group and 23% in the control group (p = 0.03). Eighteen patients suffered from partial splenic infarction after PreopAE, all treated conservatively.ConclusionPreoperative ischemic conditioning by arterial embolization before oncologic esophagectomy seems to be effective in preventing anastomotic leakage.

Background: To determine if preoperative radiation therapy allows sphincter preservation in the treatment of rectal cancer. Methods: Thirty six patients with the diagnosis of invasive, resectable, primary adenocarcinoma of the rectum limited to the pelvis were enrolled on a Phase I/II trial of preoperative radiation therapy plus low anterior resection/coloanal anastomosis. By preoperative assessment, all patients had invasive tumors (5,T 2; 31,T 3 ) involving the distal half of the rectum and clinically required an abdominoperineal resection. The median tumor size was 3.8 cm [range: 1.5-7 cm] and the median distance from the anal verge was 4 cm [range: 3-7 cm]. The whole pelvis received 46.80 Gy followed by a 3.60 Gy boost to the primary tumor bed. The median follow-up was 56 months [range: 4-121 months]. Results: Of the 35 patients who underwent resection, 5 (14%) had a complete pathologic response and 27 (77%) were able to successfully undergo a low anterior resection/coloanal anastomosis. The incidence of local failure was crude: 17% and 5-year actuarial: 21%. The 5-year actuarial survival was 64%. Analysis of sphincter function using a previously published scale was performed at the time of last follow-up in the 27 patients who underwent a low anterior resection/coloanal anastomosis. Function was good or excellent in 85%. The median number of bowel movements/day was 2 (range: 0-8). Conclusions: Our data suggest that preoperative radiation therapy allows sphincter preservation in 77% of selected patients who would otherwise require an abdominoperineal resection, and 85% have good to excellent sphincter function. Given the moderate local failure rate, we now routinely use preoperative combined modality therapy plus postoperative chemotherapy for patients with clinical T 3 disease

Full Text Available ObjectiveTo evaluate the effect and predictive value of preoperative neutrophil-lymphocyte ratio (NLR on the prognosis of patients undergoing radical resection for hepatocellular carcinoma (HCC. MethodsThe clinical data of 245 patients who received radical resection for HCC in our hospital from 2004 to 2009 were retrospectively analyzed. The effects of clinicopathological parameters including NLR on overall survival (OS time were assessed by univariate analysis using the log-rank test. The significant variables were further analyzed by multivariate analysis using the Cox regression model. ResultsUsing NLR=1.5, 2, and 3 as cut-off points, the patients were divided into four groups. The median OS time in groups with NLR＜1.5, 1.5≤NLR＜2, 2≤NLR＜3, and NLR≥3 was 39.6, 38.3, 25.4, and 19.9 months, respectively (P=0.003. Multivariate analysis showed that preoperative NLR, levels of alpha-fetoprotein and alanine aminotransferase in peripheral blood, number of tumor nodules, maximum size of tumor, and portal vein tumor thrombus were independent prognostic factors for HCC (P＜0.05. ConclusionPreoperative NLR in peripheral blood is a novel prognostic biomarker for HCC after radical resection.

Preoperative chemoradiotherapy (CRT) has become the standard treatment for patients with locally advanced rectal cancer. However, no specific biomarker has been identified to predict a response to preoperative CRT. The aim of the present study was to assess the gene expression patterns of patients with advanced rectal cancer to predict their responses to preoperative CRT. Fifty-nine rectal cancer patients were subjected to preoperative CRT. Patients were randomly assigned to receive CRT with tegafur/gimeracil/oteracil (S-1 group, n=30) or tegafur-uracil (UFT group, n=29). Gene expression changes were studied with cDNA and miRNA microarray. The association between gene expression and response to CRT was evaluated. cDNA microarray showed that 184 genes were significantly differentially expressed between the responders and the non‑responders in the S-1 group. Comparatively, 193 genes were significantly differentially expressed in the responders in the UFT group. TBX18 upregulation was common to both groups whereas BTNL8, LOC375010, ADH1B, HRASLS2, LOC284232, GCNT3 and ALDH1A2 were significantly differentially lower in both groups when compared with the non-responders. Using miRNA microarray, we found that 7 and 16 genes were significantly differentially expressed between the responders and non-responders in the S-1 and UFT groups, respectively. miR-223 was significantly higher in the responders in the S-1 group and tended to be higher in the responders in the UFT group. The present study identified several genes likely to be useful for establishing individualized therapies for patients with rectal cancer.

We sought to develop a predictive model based exclusively on preoperative factors to identify patients at risk for PrlICULOS following coronary artery bypass grafting (CABG). Retrospective analysis was performed on patients undergoing isolated CABG at a single center between June 1998 and December 2002. PrlICULOS was defined as initial admission to ICU exceeding 72 h. A parsimonious risk-predictive model was constructed on the basis of preoperative factors, with subsequent internal validation. Of 3483 patients undergoing isolated CABG between June 1998 and December 2002, 411 (11.8%) experienced PrlICULOS. Overall in-hospital mortality was higher among these patients (14.4% vs. 1.2%, Prisk predictive model of PrlICULOS in patients undergoing CABG was constructed. Based on preoperative clinical factors, a scorecard was developed allowing identification of these patients prior to surgery and allowing for strategies aimed at optimizing hospital resources.

Full Text Available Objectives: To study the correlation between Wada memory test and neuropsychometric tests which were applied preoperatively to mesialtemporal lobe epilepsy patients associated with hippocampal sclerosis (MTLE-HS who had undergone selective amygdalohippocampectomyand find out the effects of early onset epileptic seizures on atypical memory dominance.Methods: Drug-resistant 27 patients (16 left, 11 right MTLE-HS had video EEG, cranial MRI and Wada test preoperatively. Weschler visualsubtest and verbal memory processing tests were applied to all patients before surgery and the first year after the operation.Results: The number of left hemisphere memory dominant patients was 6 (22.2% and the number of atypical memory dominant patientswas 21 (77.8% according to the Wada test. There was a significant difference between the two groups when compared for epileptic seizureonset age; (p=0.042, and also a significant diffference when compared for HS (right/left side (p=0.002. When we analyzed the correlationbetween preoperative and postoperative verbal and nonverbal tests and left memory Wada dominance; in verbal memory processing tests‘delayed recall’ scores between groups were significant (p=0.042, on the other hand in patients with atypical memory dominance ‘total learning’ scores between groups were significant (p<0.001.Conclusion: As a result, we found that the earlier the onset of seizures, the more atypical the memory dominance (right or bilateral. The Wada test was effective for assessing verbal memory; on the other hand, it was inadequate for assessing visual memory dominance. If the scores of ‘delayed recall’ in verbal memory were high in the patients with typical verbal dominance and ‘total learning’ scores in the patients with atypical verbal dominance, the scores also tended to rise after the operation.

To assess the prevalence of preoperative anemia and the impact of preoperative anemia and blood transfusion requirement on 30- and 90-day complications in a cohort of patients undergoing robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC). IRARC was performed on 166 patients between June 2011 and March 2016. Prospective data were collected for patient demographics, clinical and pathologic characteristics, perioperative variables, transfusion requirements, and hospital length of stay. Thirty- and 90-day complications were classified according to the modified Memorial Sloan Kettering Cancer Center Clavien-Dindo system. Preoperative anemia was common (43.4%) and greatest in patients receiving neoadjuvant chemotherapy (48.6%) (p blood transfusion (p = 0.001). Blood transfusion required in 20.4% of patients with intraoperative and postoperative blood transfusion rate was 10.2% and 13.9%, respectively. The 30-day all complication rate and 30-day major complication rate were 55.4% and 15.7%, respectively, while 90-day all complication rate and 90-day major complication rate were 65.7% and 19.3%, respectively. Intraoperative blood transfusion was not associated with increased complications, but postoperative blood transfusion requirement was independently associated with perioperative morbidity: all 30-day complications (p = 0.003), all 90-day complications (p = 0.009), and 90-day major complications (p = 0.004). The presence of preoperative anemia in patients undergoing iRARC is not associated with increased surgical risk, although preoperative anemic patients were significantly more likely to require blood transfusion. Blood transfusion requirement and specifically postoperative blood transfusion are independently associated with perioperative morbidity and are an important factor for the optimization of postoperative outcomes.

Radionuclide liver scans were obtained in 89 preoperative patients with gastric cancer. Eight showed definite defects on liver scans. At laparotomy, 14 patients were found to have liver involvement secondary to gastric cancer. The sensitivity of liver scans to predict liver involvement is 57% (8/14), and the specificity is 100% (75/75). The patients with definite defects on liver scans had a lower rate of palliative resection of the primary tumors (2/8) than the patients with liver involvement and no scan abnormality (4/6). The patients with advanced lesions but without liver involvement had the highest probability of resecting the primary tumors (57/63 : 47 radical, and 10 palliative). Normal serum levels of liver chemistries did not preclude the presence of defects on liver scans. Additional three patients were found to have cirrhosis of the liver solely based on liver scans, which was confirmed at laparotomy. Radionuclide liver scans can predict liver involvement with very few false positives, and may discriminate patients unsuitable for laparotomy even with palliative intent.

Full Text Available Objective. Ibuprofen and pregabalin both have independent positive effects on postoperative pain. The aim of the study is researching effect of 800 mg i.v. ibuprofen in addition to preoperative single dose pregabalin on postoperative analgesia and morphine consumption in posterior lumbar interbody fusion surgery. Materials and Methods. 42 adult ASA I-II physical status patients received 150 mg oral pregabalin 1 hour before surgery. Patients received either 250 ml saline with 800 mg i.v. ibuprofen or saline without ibuprofen 30 minutes prior to the surgery. Postoperative analgesia was obtained by morphine patient controlled analgesia (PCA and 1 g i.v. paracetamol every six hours. PCA morphine consumption was recorded and postoperative pain was evaluated by Visual Analog Scale (VAS in postoperative recovery room, at the 1st, 2nd, 4th, 8th, 12th, 24th, 36th, and 48th hours. Results. Postoperative pain was significantly lower in ibuprofen group in recovery room, at the 1st, 2nd, 36th, and 48th hours. Total morphine consumption was lower in ibuprofen group at the 2nd, 4th, 8th, 12th, and 48th hours. Conclusions. Multimodal analgesia with preoperative ibuprofen added to preoperative pregabalin safely decreases postoperative pain and total morphine consumption in patients having posterior lumbar interbody fusion surgery, without increasing incidences of bleeding or other side effects.

Full Text Available Introduction: Given the difficulty in accessing to the excluded stomach after gastric bypass and the increase in gastroesophageal reflux after sleeve gastrectomy, it is justified to perform a preoperative fibrogastroscopy. The influence of the fibrogastroscopy (FGS findings in the therapeutic approach is analyzed. Patients and methods: A retrospective study of preoperative FGS findings is performed, from 04/06 to 12/12. The influence of the FGS results on the surgical technique selection, in the endoscopic or medical treatment and its relation to gastric fistula is analyzed by means of multivariate regression (confounding factors: Age, body mass index, arterial hypertension, diabetes mellitus, antiplatelet therapy, surgical technique (bariatric surgery, sleeve gastrectomy. Results: Three hundred thirty one patients are included: 32.6% biopsy of gastric lesion; 27% gastritis; 18.1% hiatal hernia; 3% metaplasia; 0.6% Barrett esophagus; 2.1% esophagitis; 0.3% dysplasia; 0.3 Schatzky's ring; 1.5% incompetent cardia; 2.4% duodenitis; 0.3% gastric erosions; 0.6% gastric xanthoma; 1.8%, gastric polyp; 1.6% duodenal ulcer; 0.6% papulo-erosive gastritis; 0.6% esophageal papilloma; 0.3% submucosal tumor. Helicobacter pylori+ 30.2% (triple therapy eradication in all patients. The FGS findings led to a variation in the surgical technique or to the completion of endoscopic treatment in 22.2% of cases. The gastric lesions did not influence the development of gastric fistula. Independent prognostic factors of fistula: Sleeve gastrectomy (7.9% vs. 2.7%; p = 0.02; OR: 1.38 IC95: 1.01-1.87 and the body mass index > 50 kg/m² (6.7% vs. 2.2%; p = 0.04; OR: 3.7 IC95: 1.12-12.4. Conclusions: The diagnosis of gastroesophageal disease through preoperative FGS motivated variations in the therapeutic approach in 52% of patients, so we consider essential to include the preoperative FGS in bariatric surgery.

Is there a role of whole-body bone scan in patients with esophageal squamous cell carcinoma

Background Correct detection of bone metastases in patients with esophageal squamous cell carcinoma is pivotal for prognosis and selection of an appropriate treatment regimen. Whole-body bone scan for staging is not routinely recommended in patients with esophageal squamous cell carcinoma. The aim of this study was to investigate the role of bone scan in detecting bone metastases in patients with esophageal squamous cell carcinoma. Methods We retrospectively evaluated the radiographic and scintigraphic images of 360 esophageal squamous cell carcinoma patients between 1999 and 2008. Of these 360 patients, 288 patients received bone scan during pretreatment staging, and sensitivity, specificity, positive predictive value, and negative predictive value of bone scan were determined. Of these 360 patients, surgery was performed in 161 patients including 119 patients with preoperative bone scan and 42 patients without preoperative bone scan. Among these 161 patients receiving surgery, 133 patients had stages II + III disease, including 99 patients with preoperative bone scan and 34 patients without preoperative bone scan. Bone recurrence-free survival and overall survival were compared in all 161 patients and 133 stages II + III patients, respectively. Results The diagnostic performance for bone metastasis was as follows: sensitivity, 80%; specificity, 90.1%; positive predictive value, 43.5%; and negative predictive value, 97.9%. In all 161 patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0.009, univariately). In multivariate comparison, absence of preoperative bone scan (P = 0.012, odds ratio: 5.053) represented the independent adverse prognosticator for bone recurrence-free survival. In 133 stages II + III patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0

Harisiadis, L.; Kopelson, G.; Chang, C.H.

1977-01-01

The peripheral blood changes were studied in 67 children who received craniospinal irradiation for posterior fossa tumors. At the completion of a cranial dose of about 3500 rad to the whole brain port, the lymphocytes were reduced to 858/mm 3 from 3084/mm 3 preoperatively. The counts of the remaining leukocytes stayed at a level somewhat higher than preoperatively; the eosinophils rose to 288/mm 3 from 125/mm 3 . With the initiation of the spinal field irradiation, which included a large proportion of the total bone marrow, the numbers of all the leukocytes decreased rapidly; the observed leukopenia was mainly secondary to neutropenia. A mechanism that was operating to restore the number of leukocytes became manifest immediately after the completion of radiotherapy, though the number of lymphocytes had not been totally restored to the preoperative level 6 years later. Irradiation of the lymphocytes that circulate through the vascular bed can explain the lymphopenia observed during cranial radiotherapy. Mild leukopenia observed in patients receiving radiotherapy through a relatively small port may be secondary to lymphopenia, and this does not necessarily indicate impaired bone marrow reserves

With declining reimbursement to health care systems, face-to-face time between patients and providers to optimize preoperative education and counseling may be challenging. Because high patient anxiety prior to surgery has been linked to more severe and persistent pain after joint replacement surgery, the Orthopedic Surgery Department at Mayo Clinic in Florida created a playlist of 16 YouTube videos aimed at creating a virtual hospital experience for primary total hip and knee joint replacement patients. A randomized trial was then performed to evaluate the potential impact of viewing this playlist on preoperative anxiety. Each patient completed a Generalized Anxiety Disorder (GAD) score assessment at the time of the routine preoperative clinic visit and then randomized based on his/her gender, type of surgery, and initial GAD score to either the control group of standard education (education at face-to-face clinical visits as well as printed educational materials) or the treatment group (standard education plus access to the YouTube playlist). On the morning of the patient's surgery, the same survey was repeated. Of the 65 patients who consented to participate in the study, 53 completed the study (82%) with 28 of 29 (97% completed) in the control group and 25 of 36 (69% completed) in the treatment group. Overall, the results showed a trend toward less anxiety in patients who viewed the YouTube videos; this was exhibited by a reduction in the median GAD score by 1 point. This trend is more clearly present in patients with high preoperative anxiety (predominantly women), as seen in the reduction of the median GAD score by 6 points in the treatment group. Although our experience is limited, our results indicate that a series of tailored videos may decrease patient anxiety preoperatively. We recommend further exploration of both this concept and the use of social media tools in preoperative patient education. Clinicaltrials.gov NCT02546180; http

Purpose: To evaluate the accuracy of pre-operative MRI for the detection of optic nerve invasion in retinoblastoma. Materials and methods: Institutional review board approval and informed consent were waived for this retrospective study. A total of 41 patients were included. Inclusion criteria were histologically proven retinoblastoma, availability of diagnostic-quality preoperative MR images acquired during the 4 weeks before surgery, unilateral retinoblastoma, and normal-sized optic nerve. Two radiologists retrospectively reviewed the MR images independently. Five imaging findings (diffuse mild optic nerve enhancement, focal strong optic nerve enhancement, optic sheath enhancement, tumor location, and tumor size) were evaluated against optic nerve invasion of retinoblastoma. The predictive performance of all MR imaging findings for optic nerve invasion was also evaluated by the receiver operating characteristic curve analysis. Results: Optic nerve invasion was histopathologically confirmed in 24% of study population (10/41). The differences in diffuse mild enhancement, focal strong enhancement, optic sheath enhancement, and tumor location between patients with optic nerve invasion and patients without optic nerve invasion were not significant. Tumor sizes were 16.1 mm (SD: 2.2 mm) and 14.9 mm (SD: 3.6 mm) in patients with and without optic nerve involvement, respectively (P = 0.444). P-Values from binary logistic regression indicated that all five imaging findings were not significant predictors of tumor invasion of optic nerve. The AUC values of all MR imaging findings for the prediction of optic nerve invasion were 0.689 (95% confidence interval: 0.499–0.879) and 0.653 (95% confidence interval: 0.445–0.861) for observer 1 and observer 2, respectively. Conclusion: Findings of MRI in patients with normal-sized optic nerves have limited usefulness in preoperatively predicting the presence of optic nerve invasion in retinoblastoma.

Full Text Available Recent studies have shown that the presence of systemic inflammation correlates with poor survival in various of cancers. The aim of this study was to determine the prognostic values of neutrophil lymphocyte ratio (NLR and platelet lymphocyte ratio (PLR in patients with small cell carcinoma of the esophagus (SCCE. Preoperative NLR and PLR were evaluated in 43 patients with SCCE from January 2001 to December 2010. The prognostic significance of both markers was then determined by both uni- and multivariate analytical methods. Receiver operating characteristic (ROC curves were also plotted to verify the accuracy of NLR and PLR for survival prediction. Patients with PLR ≥150 had significantly poorer (relapse-free survival RFS and (overall survival OS compared to patients with PLR <150. However, RFS or OS did not differ according to NLR categories (<3.5 and ≥3.5. The areas under the curve (AUC indicated that PLR was superior to NLR as a predictive factor. The results of the present study conclude that PLR is superior to NLR as a predictive factor in patients with SCCE.

Hypoxia, a prognostic factor in many types of cancer, can be detected by {sup 18}F-fluoromisonidazole (FMISO) positron emission tomography (PET). It is unclear whether hypoxia reflects the response to chemotherapy in patients with oral squamous cell carcinoma (OSCC). The correlations of FMISO-PET and FDG-PET with histological response to preoperative chemotherapy were therefore assessed in patients with OSCC. This study enrolled 22 patients with OSCC undergoing preoperative chemotherapy. The T-stages were T2 in 6 patients, T3 in 3, and T4a in 13, and the N-stages were N0 in 14 patients, N1 in 3, and N2 in 5. Each patient was evaluated by both FMISO-PET and FDG-PET before surgery, and the maximum standardized uptake value (SUV{sub max}) of FDG- and FMISO-PET and tumor-muscle ratio (TMR) of FMISO-PET were measured. The threshold for the hypoxic volume based on TMR was set at 1.25. The histological response to preoperative chemotherapy was evaluated using operative materials. FMISO-PET and FDG-PET detected uptake by primary OSCCs in 15 (68 %) and 21 (95 %) patients, respectively, and median SUV{sub max}s of FMISO- and FDG-PET in the primary site were 2.0 (range, 1.3-3.5) and 16.0 (range, 1.0-32.2), respectively. The median of FMISO TMR was 1.5 (range, 0.99-2.96). There were five cases whose FMISO TMR was less than 1.25. Histological evaluation showed good response to preoperative chemotherapy in 7 patients (32 %) and poor response in 15 (68 %). Good response was significantly more prevalent in patients with negative than positive FMISO uptake (P < 0.001) and without the hypoxic area evaluated by FMISO-PET TMR (P = 0.04), whereas FDG uptake was not significantly correlated with response to chemotherapy response. Multivariate logistic regression analysis showed that FMISO uptake was an independent significant predictor of response to preoperative chemotherapy (P = 0.03, odds ratio = 0.06, 95 % confidence interval = 0.004-0.759).
