The year of 1999 marks the 75th anniversary of Viktor von Hacker's retirement as chairman of the Department of Surgery at Karl-Franzens University School of Medicine in Graz. He was a favored pupil of Theodor Billroth (1829-1894). When he took his professorship at Graz in 1903, the present hospital, then as now one of the largest in Europe, was still in planning, and he immediately involved himself in all the subsequent developmental stages. Now we are again living through a stage of major reconstruction and expansion within the context of the "LKH 2000" project which also encompasses the surgical department and wards, most of which have generally remained unchanged since Hacker's time. During his 21 years as chairman of the department, Hacker made major contributions in the fields of gastro-intestinal surgery, esophageal surgery and especially esophagoscopy, as well as plastic surgery. Towards the end of his career, 70 years ago, Viktor von Hacker was named an honorary member of the German Society of Surgery. For these reasons, the man and his work should be recalled.

Full Text Available Little is known about the long term occurrence and prevalence of upper abdominal complaints after previous partial gastrectomy. Therefore, a retrospective, uncontrolled, cross-sectional, descriptive, clinical, endoscopic study was done. A questionnaire was mailed to patients who had undergone partial gastrectomy and been sent for upper gastrointestinal endoscopy. Eight questions were scored on a five-point Likert scale, and a symptom score was calculated. During the five-year study period, 189 patients (137 men, 52 women were identified as having had a partial gastrectomy -- 143 (76% received the Billroth II operation and 46 (24% received the Billroth I operation. The questionnaire was mailed to 124 patients, of whom 79 (64% responded. Eighty-eight per cent of patients had undergone surgery more than 15 years earlier. Fifty-nine patients (75% suffered from upper abdominal symptoms. Regurgitation of food, retrosternal heartburn and bile reflux occurred significantly more often in patients who underwent the Billroth II operation. The mean symptom score of patients who underwent Billroth I resection was significantly lower (4.5 [SD 3.6] than that of patients who underwent Billroth II resection (7.1 [SD 4.4](P=0.04. One or more symptoms indicative of dumping were found in 70% of patients who underwent Billroth II resection and in 59% of patients who underwent Billroth I resection (not significant. Many patients who had undergone a partial gastrectomy developed upper abdominal symptoms during long term follow-up that were not specifically linked to dumping.

Laparoscopy-Assisted Billroth I Gastrectomy for Ectopic Pancreas in the Prepyloric Region

Full Text Available Ectopic pancreatic tissue is an uncommon developmental anomaly. The condition mostly occurs in the gastrointestinal tract and is usually asymptomatic. It rarely causes symptoms of inflammation, bleeding and perforation, and has potential for malignant change. Though it is an uncommon condition, cases of ectopic pancreas have been reported worldwide. Preoperative diagnosis of ectopic pancreas is challenging because of its nonspecific symptoms and signs. Owing to the revolution of minimally invasive surgery, submucosal tumors of the stomach can be resected by laparoscopic techniques. We have earlier reported on a case of ectopic pancreas in the stomach treated by robotics-assisted laparoscopic wedge resection. Herein, we report a case of ectopic pancreas in the prepyloric region of the stomach. A 44-year-old female presented with a two-week history of epigastralgia with radiation to the back. She received endoscopy check-up which disclosed a mass in the stomach. By endoscopic findings, a submucosal lesion in the prepyloric region with umbilical folding on the mucosa was identified. The umbilical folding on the mucosa hint the orifice of the duct of ectopic pancreas into the gastric mucosa suggestive of ectopic pancreas. Contrast-enhanced abdominal computed tomography showed a 5 cm cystic mass with heterogeneous content. To sum it up, the patient was diagnosed as ectopic pancreas in the stomach. She underwent laparoscopy-assisted antrectomy with Billroth I anastomosis (excision of the antrum and prepyloric region with reconstruction of gastrointestinal continuity by gastroduodenostomy and had an uneventful hospitalization course. The histopathology of the resected tumor demonstrated ectopic pancreatic tissue in the gastric wall. To the best of our knowledge, excision of gastric ectopic pancreas using laparoscopy-assisted antrectomy with Billroth I anastomosis has never been reported in the literature.

In the present study, the Billroth-I anastomosis with the biofragmentable anastomosis ring was examined in dogs. 24 dogs were randomized into a group of manual suturing (n = 12) and a BAR-group (n = 12). In the group of manual suturing, a distal gastric resection and gastroduodenostomy with sero-submucous suture was performed. In the BAR-group, the distal gastric resection was done with the linear stapler PLC-75, whereby the BAR gastroduodenostomy crossed the stapling line. The dogs were evaluated on p.o. days 4, 14, and 30 and tested for bursting strength and bursting location, appearance of mucosa, hydroxyprolin concentration, and histologic features. There was no functional disorder in the gastrointestinal transit in any animal; in summary with regard to the various parameters, the crossing of BAR and stapling line does not represent any additional risk factor in the Billroth-I anastomosis in dogs.

to analyze the surgical treatment results in the complicated duodenal or gastric chronic peptic ulcer over 15 years. METHODS: A retrospective and descriptive study was conducted in patients presenting with complicated peptic ulcer by exeresis. Patients (n=45 were seen by some of us in the "Amalia Simoni" Clinical Surgical of Camaguey province from January, 1989 to December, 2004. RESULTS: Disease was more frequent in male sex (82,22% and in ages from 36 to 50 years (46,67%. The 95,56% of patients treated suffered from duodenal ulcer and the main criterion for surgery was its unmanageable condition (62,22%. Endoscopy was very useful for diagnosis of this entity. All operated on underwent vagotomy with antrectomy; in the 68,89% we performed a Billroth's II anastomosis and in remainder (31,11% it was of Billroth I type. There was a similar figure of early complications related to techniques used and among them prevails the anastomosis bleeding and delay evacuation. There were more late complications in type Billroth II anastomosis than in the Billroth I. Surgical results were excellent and very good in the 89% of cases. The enterocolitis variant has the great percentage of non-satisfactory results (9,09%. Only two patients had poor results, although there wasn't operative mortality. CONCLUSIONS: This kind of surgery is indicated only in cases of complicated peptic ulcer. It is not the choice method in ulcer patients, but in its use it is necessary to know about different techniques and its use. Thus, we must to know a lot about this procedure.

Full Text Available Introduction. This study aims to investigate the reasons that discourage the patients affected by OSAS to undergo orthognathic surgery and compares the postoperative discomfort of phase I (soft tissue surgery and phase II (orthognathic surgery procedures for treatment of OSAS. Material and Methods. A pool of 46 patients affected by OSAS was divided into two groups: “surgery patients” who accepted surgical treatments of their condition and “no surgery patients” who refused surgical procedures. The “surgery patients” group was further subdivided into two arms: patients who accepted phase I procedures (IP and those who accepted phase II (IIP. To better understand the motivations behind the refusal of II phase procedures, we asked the patients belonging to both the IP group and “no surgery” group to indicate the main reason that influenced their decision to avoid II phase procedures. We also monitored and compared five parameters of postoperative discomfort: pain, painkiller assumption, length of hospitalization, foreign body sensation, and diet assumption following IP and IIP procedures. Results. The main reason to avoid IIP procedures was the concern of a more severe postoperative discomfort. Comparison of the postoperative discomfort following IP versus IIP procedures showed that the former scored worse in 4 out of 5 parameters analyzed. Conclusion. IIP procedures produce less postoperative discomfort. IIP procedures, namely, orthognathic surgery, should be the first choice intervention in patients affected by OSAS and dentoskeletal malformation.

The aim was to examine the influence of different modalities of peptic ulcer surgery on the gastric emptying (GE) pattern and related serum level changes of selected gut hormones. Fifty eight subjects were examined. In 48 of them peptic ulcer surgery was performed at least six months before the examination: Billroth I (B1) in 11, Billroth II (B2) in 16, B1 with the selective vagotomy - Harkins 1 (H1) in 9 and B2 with the selective vagotomy - Harkins 2 (H2) in 12. Ten healthy volunteers (C) were also examined. The results of gastric emptying showed that the lag phase duration was inversely related to the GE rates, and the GE pattern was linear in both controls (C) and in operated patients, except in B2 group, in which the GE pattern was exponential. In comparison with C group, GE was slower in B1, H1 and H2 groups, and faster in B2 group. The plasma gastrin values in C group, showing two peaks, were higher in relation to other groups. In relation to C group, higher values of motilyn were obtained in patients after the selective vagotomy. The plasma somatostatin values recorded in B1 and H1 groups, showing the marked peaks, were higher in relation to C group. In relation to C group the highest plasma neurotensin values were obtained in B2 group. In order to understand entirely the influence of peptic ulcer surgery on the GI function, further research of the role of specific hormones and neuropeptides is needed, which would enable more precise selection of the therapy in order to prevent postvagotomy and postgastrectomy syndromes.

We have reported the short-term results of pylorus reconstruction gastrectomy (PRG) that prevents duodenogastric reflux (DGR) and remnant gastritis after distal gastrectomy. We herein report the long-term results of the PRG. PRG was performed in 37 patients (age 31 to 86 [mean 67.8 ± 12.3] years, male:female = 22:15) with gastric cancer from June 2006 through December 2013. We examined the long-term outcome in 28 patients (age 41 to 86 [mean 67.0 ± 10.7] years, male:female = 18:10) that passed over 3 years after surgery (LTR 44.1 ± 11.7 months), and compared with their short-term result after the operation (STR 13.1 ± 6.9 months). The adverse events of gastric surgery evaluated in this study consisted of the degree of remnant gastritis, the presence of dumping syndrome, and degree of weight loss (%). There was no difference in the degree of DGR and remnant gastritis by gastroscopic finding between LTR and STR after PRG (P = 0.21). Statistically, there was no difference in the bile acid concentration of remnant gastric juice between LTR and STR (108.4 ± 254.1 vs. 94.0 ± 208.6 μmol/L, P = 0.33), and weight loss of LTR was the same as that of STR (5.67 ± 7.08 vs. 4.59 ± 5.63%, P = 0.34). There were few morphological changes in the reconstructed pylorus by the long-term course, but 2 patients showed mild atrophy. The form of reconstructed pylorus and the effect that reduces side effects of Billroth I seem to last for a long time.

Facial asymmetry is one of the main concerns in patients with a dentofacial deformity. The aims of the study were to (1) evaluate the changes in facial asymmetry after bimaxillary surgery for asymmetric skeletal class II deformity and (2) compare preoperative and postoperative facial asymmetry of class II patients with normal controls. The facial asymmetry was assessed for 30 adults (21 women and 9 men, mean age: 29.3 years) who consecutively underwent bimaxillary surgery for asymmetric skeletal class II deformity using cone-beam computed tomography before and at least 6 months after surgery. Thirty soft tissue and two dental landmarks were identified on each three-dimensional facial image, and the asymmetry index of each landmark was calculated. Results were compared with those of 30 normal control subjects (21 women and 9 men, mean age: 26.2 years) with skeletal class I structure. Six months after surgery, the asymmetric index of the lower face and total face decreased significantly (17.8 ± 29.4 and 16.6 ± 29.5 mm, respectively, both p class II patients had residual chin asymmetry. The postoperative total face asymmetric index was positively correlated with the preoperative asymmetric index (r = 0.37, p class II deformity resulted in a significant improvement in lower face asymmetry. However, approximately 50% of the patients still had residual chin asymmetry. The total face postoperative asymmetry was moderately related to the initial severity of asymmetry. These findings could help clinicians better understand orthognathic outcomes on different facial regions for patients with asymmetric class II deformity.

Advantages of the formation of gastroduodenal anastomosis using the microsurgical precision technique as compared to the two-row interrupted Albert-Lembert suture and the one-row suture of Pirogov-Mateshuk were established in an experimental investigation in 63 dogs. The article describes the precision suture technique proposed by the authors which was used in Billroth-I resection of the stomach in 15 patients. It was shown that the use of the precision suture resulted in healing by the first intention type, without motor evacuatory disorders and with shorter time of hospital treatment.

Objective: To assess the systemic stress reaction in patients with open chest surgery through measurement of the changes of serum cortisol and plasma AT-II levels during peri-operative stage. Methods: Serum cortisol and plasma AT-II levels were measured with RIA in 35 patients underwent open chest surgery both before and after the operative procedure. Results: The serum level of cortisol and plasma levels of AT-II were significantly higher after operation than those before operation ( P < 0.05 ). Also, the systolic pressure and heart rate were increased significantly (P<0.05). The post-operative heart rate was significantly positively correlated with both cortisol and AT-II levels (P<0.05). Conclusion: Stress reaction is evident in patients after open chest surgery with increase of serum cortisol and plasma AT-II levels. The stress reaction, if excessive, should be properly dealt with.

2012-05-01

Full Text Available Abstract Background This retrospective study compared the clinicopathological results among three groups divided by time sequence to evaluate the impact of introducing laparoscopic surgery on long-term oncological outcomes for right-sided colon cancer. Methods From April 1986 to December 2006, 200 patients who underwent elective surgery with stage II and III right-sided colon cancer were analyzed. The period for group I referred back to the time when laparoscopic approach had not yet been introduced. The period for group II was designated as the time when first laparoscopic approach for right colectomy was carried out until we overcame its learning curve. The period for group III was the period after overcoming this learning curve. Results When groups I and II, and groups II and III were compared, overall survival (OS did not differ significantly whereas disease-free survival (DFS in groups I and III were statistically higher than in group II (P = 0.042 and P = 0.050. In group III, laparoscopic surgery had a tendency to provide better long-term OS ( P = 0.2036 and DFS ( P = 0.2356 than open surgery. Also, the incidence of local recurrence in group III (2.6% was significantly lower than that in groups II (7.4% and I (12.1% ( P = 0.013. Conclusions Institutions should standardize their techniques and then provide fellowship training for newcomers of laparoscopic colon cancer surgery. This technique once mastered will become the gold standard approach to colon surgery as it is both safe and feasible considering the oncological and technical aspects.

To (1) evaluate rates of surgery for clinical stage I-II pancreatic ductal adenocarcinoma (PDAC), (2) identify predictors of not undergoing surgery, (3) quantify the degree to which patient- and hospital-level factors explain differences in hospital surgery rates, and (4) evaluate the association between adjusted hospital-specific surgery rates and overall survival (OS) of patients treated at different hospitals. Curative-intent surgery for potentially resectable PDAC is underutilized in the United States. Retrospective cohort study of patients ≤85 years with clinical stage I-II PDAC in the 2004 to 2014 National Cancer Database. Mixed effects multivariable models were used to characterize hospital-level variation across quintiles of hospital surgery rates. Multivariable Cox proportional hazards models were used to estimate the effect of adjusted hospital surgery rates on OS. Of 58,553 patients without contraindications or refusal of surgery, 63.8% underwent surgery, and the rate decreased from 2299/3528 (65.2%) in 2004 to 4412/7092 (62.2%) in 2014 (P < 0.001). Adjusted hospital rates of surgery varied 6-fold (11.4%-70.9%). Patients treated at hospitals with higher rates of surgery had better unadjusted OS (median OS 10.2, 13.3, 14.2, 16.5, and 18.4 months in quintiles 1-5, respectively, P < 0.001, log-rank). Treatment at hospitals in lower surgery rate quintiles 1-3 was independently associated with mortality [Hazard ratio (HR) 1.10 (1.01, 1.21), HR 1.08 (1.02, 1.15), and HR 1.09 (1.04, 1.14) for quintiles 1-3, respectively, compared with quintile 5] after adjusting for patient factors, hospital type, and hospital volume. Quality improvement efforts are needed to help hospitals with low rates of surgery ensure that their patients have access to appropriate surgery.

Surgical management of ophthalmic Graves' disease traditionally involves, in order, orbital decompression, followed by strabismus surgery and eyelid surgery. Nunery et al. previously described two distinct sub-types of patients with ophthalmic Graves' disease; Type I patients exhibit no restrictive myopathy (no diplopia) as opposed to Type II patients who do exhibit restrictive myopathy (diplopia) and are far more likely to develop new-onset worsening diplopia following medial wall and floor decompression. Strabismus surgery involving extra-ocular muscle recession has, in turn, been shown to potentially worsen proptosis. Our experience with Type II patients who have already undergone medial wall and floor decompression and strabismus surgery found, when additional decompression is necessary, deep lateral wall decompression (DLWD) appears to have a low rate of post-operative primary-gaze diplopia. A case series of four Type II ophthalmic Graves' disease patients, all of whom had already undergone decompression and strabismus surgery, and went on to develop worsening proptosis or optic nerve compression necessitating further decompression thereafter. In all cases, patients were treated with DLWD. Institutional Review Board approval was granted by the University of Kansas. None of the four patients treated with this approach developed recurrent primary-gaze diplopia or required strabismus surgery following DLWD. While we still prefer to perform medial wall and floor decompression as the initial treatment for ophthalmic Graves' disease, for proptosis following consecutive strabismus surgery, DLWD appears to be effective with a low rate of recurrent primary-gaze diplopia.

Arpad Gerster and Max Thorek contributions to American surgery.

The legacy and the influence on American surgery is discussed of two Hungarian born surgeons: Arpad Gerster (1848-1923) and Max Thorek (1880-1960). Both of them were born in Northern Hungary, then part of the Austro-Hungarian Monarchy, today Slovakia. Gerster got his medical education in Vienna The influence of Theodor Billroth left everlasting impressions in him. In 1874 he arrived in New York and became the first doctor in town who practiced exclusively surgery. He became an attending surgeon in The German Hospital and later at Mount Sinai Hospital. Gerster modernized the hospital's functions and services, introducing the rotation system, and also made the original observation that dissemination of cancer may be caused by surgery. His aseptic methods were revolutionary at the time. Max Thorek arrived in Chicago in 1897. With a fantastic endurance he overwhelmed all barriers and became a doctor. He started his practice in one of Chicago's poor immigrant neighborhoods, but stepwise he could excel and in 1911 he co-founded The American Hospital. His ideas of modernizing surgery became reality. Thorek is one of the first who practiced plastic surgery, and his contribution by writing about surgical errors and safeguards became a great success. He founded the International College of Surgeons, a result of his widespread relations among surgeons all over the world. The parallels in the lives of these great surgeons: solid education, knowledge of languages, talent for music, literature, and arts, creative thinking combined with hard work, good humor, as well as a social conscience led them to make groundbreaking contributions to American and international surgery.

Surgery-induced hippocampal angiotensin II elevation causes blood-brain barrier disruption via MMP/TIMP in aged rats

Full Text Available Reversible BBB disruption has been uniformly reported in several animal models of postoperative cognitive dysfunction (POCD. Nevertheless, the precise mechanism underlying this occurrence remains unclear. Using an aged rat model of POCD, we investigated the dynamic changes in expression of molecules involved in BBB disintegration, matrix metalloproteinase-2 (MMP-2 and -9 (MMP-9, as well as three of their endogenous tissue inhibitors (TIMP-1, -2, -3, and tried to establish the correlation between MMP/TIMP balance and surgery-induced hippocampal BBB disruption. We validated the increased hippocampal expression of angiotensin II (Ang II and Ang II receptor type 1 (AT1 after surgery. We also found MMP/TIMP imbalance as early as 6 h after surgery, together with increased BBB permeability and decreased expression of Occludin and zonula occludens-1 (ZO-1, as well as increased basal lamina protein laminin at 24 h postsurgery. The AT1 antagonist candesartan restored MMP/TIMP equilibrium and modulated expression of Occludin and laminin, but not ZO-1, thereby improving BBB permeability. These events were accompanied by suppression of the surgery-induced canonical nuclear factor-κB (NF-κB activation cascade. Nevertheless, AT1 antagonism did not affect nuclear receptor peroxisome proliferator-activated receptor-γ expression. Collectively, these findings suggest that surgery-induced Ang II release impairs BBB integrity by activating NF-κB signaling and disrupting downstream MMP/TIMP balance via AT1 receptor.

Time-to-surgery from cancer diagnosis has increased in the United States. We aimed to determine the association between time-to-surgery and oncologic outcomes in patients with resectable pancreatic ductal adenocarcinoma undergoing upfront surgery. The 2004-2012 National Cancer Database was reviewed for patients undergoing curative-intent surgery without neoadjuvant therapy for clinical stage I-II pancreatic ductal adenocarcinoma. A multivariable Cox model with restricted cubic splines was used to define time-to-surgery as short (1-14 days), medium (15-42), and long (43-120). Overall survival was examined using Cox shared frailty models. Secondary outcomes were examined using mixed-effects logistic regression models. Of 16,763 patients, time-to-surgery was short in 34.4%, medium in 51.6%, and long in 14.0%. More short time-to-surgery patients were young, privately insured, healthy, and treated at low-volume hospitals. Adjusted hazards of mortality were lower for medium (hazard ratio 0.94, 95% confidence interval, .90, 0.97) and long time-to-surgery (hazard ratio 0.91, 95% confidence interval, 0.86, 0.96) than short. There were no differences in adjusted odds of node positivity, clinical to pathologic upstaging, being unresectable or stage IV at exploration, and positive margins. Medium time-to-surgery patients had higher adjusted odds (odds ratio 1.11, 95% confidence interval, 1.03, 1.20) of receiving an adequate lymphadenectomy than short. Ninety-day mortality was lower in medium (odds ratio 0.75, 95% confidence interval, 0.65, 0.85) and long time-to-surgery (odds ratio 0.72, 95% confidence interval, 0.60, 0.88) than short. In this observational analysis, short time-to-surgery was associated with slightly shorter OS and higher perioperative mortality. These results may suggest that delays for medical optimization and referral to high volume surgeons are safe. Published by Elsevier Inc.

Bilateral sagittal split osteotomy: Surgery first approach for correction of skeletal Class II

Full Text Available Most of the skeletal malocclusions which require orthognathic surgeries are treated by traditional approach which requires time-consuming and unesthetic presurgical orthodontic phase. Surgery first approach (SFA avoids these disadvantages of the traditional approach. A 24-year-old female patient with skeletal and dental class II malocclusion due to retrognathic mandible was treated with SFA. Bilateral sagittal split osteotomy with mandibular advancement was done immediately after initial alignment and closure of the existing spaces in the maxillary arch. Angle's class I molar and canine relation was achieved after surgery. Bonding of the mandibular arch was done after 1 month of orthognathic surgery and treatment was completed within 13 months. A wrap-around retainer was placed in upper arch, and bonded lingual retainer was given in the lower arch.

Sodium pertechnetate Tc 99m antral scan in the diagnosis of retained gastric antrum

Lee, C.H.; P'eng, F.K.; Yeh, P.H.

1984-01-01

Retained gastric antrum (RGA) is a major factor in recurrent peptic ulcer. We studied 121 patients with proven anastomotic ulcers following subtotal gastrectomy and Billroth II reconstruction with sodium pertechnetate Tc 99m to determine the presence of RGA. Of the patients, 59 required surgery, 22 had RGA, and 16 had a positive scan for RGA. This noninvasive examination has 100% specificity. If RGA is identified before operation, minimal time is wasted in exploration of the abdomen, which is especially important in dealing with emergency cases. When an antral scan is negative for RGA, the surgeon is still advised to search for this condition

Full Text Available Objectives. The pectoral nerve block type II (PECS II block is widely used for postoperative analgesia after breast surgery. This study evaluated the analgesic efficacy of PECS II block in patients undergoing breast-conserving surgery (BCS and sentinel lymph node biopsy (SNB. Methods. Patients were randomized to the control group (n=40 and the PECS II group (n=40. An ultrasound-guided PECS II block was performed after induction of anesthesia. The primary outcome measure was opioid consumption, and the secondary outcome was pain at the breast and axillary measured using the Numerical Rating Scale (NRS 24 hours after surgery. Opioid requirement was assessed according to tumor location. Results. Opioid requirement was lower in the PECS II than in the control group (43.8 ± 28.5 µg versus 77.0 ± 41.9 µg, p<0.001. However, the frequency of rescue analgesics did not differ between these groups. Opioid consumption in the PECS II group was significantly lower in patients with tumors in the outer area than that in patients with tumors in the inner area (32.5 ± 23.0 µg versus 58.0 ± 29.3 µg, p=0.007. The axillary NRS was consistently lower through 24 hr in the PECS II group. Conclusion. Although the PECS II block seemed to reduce pain intensity and opioid requirements for 24 h after BCS and SNB, these reductions may not be clinically significant. This trial is registered with Clinical Research Information Service KCT0002509.

Focal cortical dysplasia (FCD) is one important cause of drug-resistant epilepsy potentially curable by epilepsy surgery. We investigated the options of using neuronavigation and intraoperative magnetic-resonance tomographical imaging (MRI) to avoid residual epileptogenic tissue during resection of patients with FCD II to improve seizure outcome. Altogether, 24 patients with FCD II diagnosed by MRI (16 female, 8 male; mean age 34 ± 10 years) suffered from drug-resistant electroclinical and focal epilepsy for a mean of 20.7 ± 5 years. Surgery was performed with preoperative stereoelectroencephalography (in 15 patients), neuronavigation, and intraoperative 1.5T-iopMRI in all 24 investigated patients. In 75% of patients (18/24), a complete resection was performed. In 89% (16/18) of completely resected patients, we documented an Engel I seizure outcome after a mean follow-up of 42 months. All incompletely resected patients had a worse outcome (Engel II-III, P < 0.0002). Patients with FCD IIB had also significant better seizure outcome compared with patients diagnosed as having FCD IIA (82% vs. 28%, P < 0.02). In 46% (11/24) of patients, intraoperative second-look surgeries due to residual lesions detected during the intraoperative MRI were performed. In these 11 patients, there were significant more completely seizure free patients (73% vs. 38% Engel IA), compared with 13 patients who finished surgery after the first intraoperative MRI (P < 0.05). Excellent seizure outcome after surgery of patients with FCD II positively correlated with the amount of resection, histologic subtype, and the use of intraoperative MRI, especially when intraoperative second-look surgeries were performed.

The benefits of cardiac surgery are sometimes difficult to predict and the decision to operate on a given individual is complex. Machine Learning and Decision Curve Analysis (DCA) are recent methods developed to create and evaluate prediction models. We conducted a retrospective cohort study using a prospective collected database from December 2005 to December 2012, from a cardiac surgical center at University Hospital. The different models of prediction of mortality in-hospital after elective cardiac surgery, including EuroSCORE II, a logistic regression model and a machine learning model, were compared by ROC and DCA. Of the 6,520 patients having elective cardiac surgery with cardiopulmonary bypass, 6.3% died. Mean age was 63.4 years old (standard deviation 14.4), and mean EuroSCORE II was 3.7 (4.8) %. The area under ROC curve (IC95%) for the machine learning model (0.795 (0.755-0.834)) was significantly higher than EuroSCORE II or the logistic regression model (respectively, 0.737 (0.691-0.783) and 0.742 (0.698-0.785), p machine learning model, in this monocentric study, has a greater benefit whatever the probability threshold. According to ROC and DCA, machine learning model is more accurate in predicting mortality after elective cardiac surgery than EuroSCORE II. These results confirm the use of machine learning methods in the field of medical prediction.

Full Text Available Background This is a validation study comparing the European System for Cardiac Operative Risk Evaluation (EuroSCORE II with the previous additive (AES and logistic EuroSCORE (LES and the Society of Thoracic Surgeons’ (STS risk prediction algorithm, for patients undergoing valve replacement with or without bypass in Pakistan. Patients and Methods Clinical data of 576 patients undergoing valve replacement surgery between 2006 and 2013 were retrospectively collected and individual expected risks of death were calculated by all four risk prediction algorithms. Performance of these risk algorithms was evaluated in terms of discrimination and calibration. Results There were 28 deaths (4.8% among 576 patients, which was lower than the predicted mortality of 5.16%, 6.96% and 4.94% by AES, LES and EuroSCORE II but was higher than 2.13% predicted by STS scoring system. For single and double valve replacement procedures, EuroSCORE II was the best predictor of mortality with highest Hosmer and Lemmeshow test (H-L p value (0.346 to 0.689 and area under the receiver operating characteristic (ROC curve (0.637 to 0.898. For valve plus concomitant coronary artery bypass grafting (CABG patients actual mortality was 1.88%. STS calculator came out to be the best predictor of mortality for this subgroup with H-L p value (0.480 to 0.884 and ROC (0.657 to 0.775. Conclusions For Pakistani population EuroSCORE II is an accurate predictor for individual operative risk in patients undergoing isolated valve surgery, whereas STS performs better in the valve plus CABG group.

Patients undergoing minimally invasive cardiac surgery have the potential for significant pain from the thoracotomy site. We report the successful use of pectoral nerve block types I and II (Pecs I and II) as rescue analgesia in a patient undergoing minimally invasive mitral valve repair. In this case, a 78-year-old man, with no history of chronic pain, underwent mitral valve repair via right anterior thoracotomy for severe mitral regurgitation. After extubation, he complained of 10/10 pain at the incision site that was minimally responsive to intravenous opioids. He required supplemental oxygen because of poor pulmonary mechanics, with shallow breathing and splinting due to pain, and subsequent intensive care unit readmission. Ultrasound-guided Pecs I and II blocks were performed on the right side with 30 mL of 0.2% ropivacaine with 1:400,000 epinephrine. The blocks resulted in near-complete chest wall analgesia and improved pulmonary mechanics for approximately 24 hours. After the single-injection blocks regressed, a second set of blocks was performed with 266 mg of liposomal bupivacaine mixed with bupivacaine. This second set of blocks provided extended analgesia for an additional 48 hours. The patient was weaned rapidly from supplemental oxygen after the blocks because of improved analgesia. Pectoral nerve blocks have been described in the setting of breast surgery to provide chest wall analgesia. We report the first successful use of Pecs blocks to provide effective chest wall analgesia for a patient undergoing minimally invasive cardiac surgery with thoracotomy. We believe that these blocks may provide an important nonopioid option for the management of pain during recovery from minimally invasive cardiac surgery.

The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular joint symptoms of skeletal CI II patients by means of magnetic resonance imaging. For this purpose, fifteen patients with skeletal CI II malocclusion, aged 19-32 years (mean 23 years), 10 women and 5 men, from the Isfahan Department of Oral and Maxillofacial Surgery were studied. All received LeFort I and bilateral sagittal split osteotomy (BSSO) osteotomies and all patients received pre- and post-surgical orthodontic treatment. Magnetic resonance imaging was performed 1 day preoperatively and 3 month postoperatively. Descriptive statistics and Wilcoxon and Mc-Nemar tests were used for statistical analysis. P surgery (mean=5.74±1.21). After surgery disc position range was 4.36 to 7.40 (mean=5.65±1.06). Statistical analysis proved that although TM disc tended to move anteriorly after BSSO surgery, this difference was not statistically significant ( p valuesurgery does not alter the disc and condyle relationship. Therefore, it has minimal effects on intact and functional TM joint. Key words: Orthognathic surgery, skeletal class 2, magnetic resonance imaging, temporomandibular disc.

The function of intestinal absorption and gastric and pancreatic secretion were observed to evaluate several factors affected to intestinal absorption in cases of carcinoma of esophagus and gastric cardia after operation. To compare fat absorption and assimilation between medium chain triglyceride (MCT) and long chain triglyceride (LCT), /sup 14/C-labeled fats were used. The effect of different types of anastomosis; i.e. Billroth I and Billroth II type-pathway, and also the effect of truncal vagotomy on digestion and absorption of fats was studied. In results, the types of anastomosis and truncal vagotomy had no significant effect on digestion and absorption of carbohydrate, but the digestion and absorption of protein and fat were impaired after operation, especially in fat. In Billroth I type-pathway, the impaired digestion and absorption were slight. In Billroth II type-pathway, imbalance in the mixing time of the diet and the digestive juice according to the dumping of ingested food into jejunum and quick passage through the jejunum; so called pancreatico-cibal asynchrony, probably caused impaired digestion of fat. It was considered that truncal vagotomy had caused steatorrhea in the early stage of postoperation. Gastric remnant and reconstructive stomach almost lost its secretory function after operation of esophageal cancer, but pancreatic exocrine secretory function remained after vagotomy. Intestinal absorption of MCT was better than it was of LCT even in cases of postoperative malabsorption. So MCT administration is considered as effective method for caloric intake in cases of esophageal cancer and cancer of gastric cardia, which have operative risk and take long time for the recovery in the function of digestion and absorption after operation.

Billroth-I (BI) is a simple, physiological method of reconstruction following distal gastrectomy. In actuality, postoperative QOL is by no means favorable due to the high incidence of post-gastrectomy syndrome. The aim of this study is to assess the safety and efficacy of boomerang-shaped jejunal interposition (BJI) after distal gastrectomy. Sixty-six patients with early gastric cancer underwent the BI procedure (n = 33) or BJI (n = 33) after distal gastrectomy, following which they were compared for 5 years. Tumor characteristics, operative details, postoperative complications and complaints, number of meals, and body weight were analyzed. Patients were followed up by endoscopy every 12 months. There were no significant differences in the incidence of postoperative complications. The incidence of heartburn (30 vs. 0 %, P = 0.0009) and oral bitterness (33 vs. 6 %, P = 0.0112) were significantly lower in the BJI cases. Endoscopic findings revealed significantly lower incidences of reflux esophagitis (24 vs. 0 %, P = 0.0051) and remnant gastritis (70 vs. 3 %, P < 0.0001) in the BJI group. The incidence of food stasis was low in both groups (12 vs. 15 %). In the BJI group, 30 patients (90 %) were eating 3 meals/day within 12 months, whereas in the BI group, 16 patients (48 %) were still eating 5 meals/day at 12 months or later. BJI is as safe as BI, but is better in terms of improvement in bile reflux and food intake without stasis. This procedure, therefore, appears to be a useful method for reconstruction after distal gastrectomy.

A systematic review of the European System for Cardiac Operative Risk Evaluation (euroSCORE) II performance for prediction of operative mortality after cardiac surgery has not been performed. We conducted a meta-analysis of studies based on the predictive accuracy of the euroSCORE II. We searched the Embase and PubMed databases for all English-only articles reporting performance characteristics of the euroSCORE II. The area under the receiver operating characteristic curve, the observed/expected mortality ratio, and observed-expected mortality difference with their 95% confidence intervals were analyzed. Twenty-two articles were selected, including 145,592 procedures. Operative mortality occurred in 4293 (2.95%), whereas the expected events according to euroSCORE II were 4802 (3.30%). Meta-analysis of these studies provided an area under the receiver operating characteristic curve of 0.792 (95% confidence interval, 0.773-0.811), an estimated observed/expected ratio of 1.019 (95% confidence interval, 0.899-1.139), and observed-expected difference of 0.125 (95% confidence interval, -0.269 to 0.519). Statistical heterogeneity was detected among retrospective studies including less recent procedures. Subgroups analysis confirmed the robustness of combined estimates for isolated valve procedures and those combined with revascularization surgery. A significant overestimation of the euroSCORE II with an observed/expected ratio of 0.829 (95% confidence interval, 0.677-0.982) was observed in isolated coronary artery bypass grafting and a slight underestimation of predictions in high-risk patients (observed/expected ratio 1.253 and observed-expected difference 1.859). Despite the heterogeneity, the results from this meta-analysis show a good overall performance of the euroSCORE II in terms of discrimination and accuracy of model predictions for operative mortality. Validation of the euroSCORE II in prospective populations needs to be further studied for a continuous

We conducted a multi-center pilot Phase II study to examine the safety of robotic rectal cancer surgery performed using the da Vinci Surgical System during the introduction period of robotic rectal surgery at two institutes based on surgical outcomes. This study was conducted with a prospective, multi-center, single-arm, open-label design to assess the safety and feasibility of robotic surgery for rectal cancer (da Vinci Surgical System). The primary endpoint was the rate of adverse events during and after robotic surgery. The secondary endpoint was the completion rate of robotic surgery. Between April 2014 and July 2016, 50 patients were enrolled in this study. Of these, 10 (20%) had rectosigmoid cancer, 17 (34%) had upper rectal cancer, and 23 (46%) had lower rectal cancer; six underwent high anterior resection, 32 underwent low anterior resection, 11 underwent intersphincteric resection, and one underwent abdominoperineal resection. Pathological stages were Stage 0 in 1 patient, Stage I in 28 patients, Stage II in 7 patients and Stage III in 14 patients. Pathologically complete resection was achieved in all patients. There was no intraoperative organ damage or postoperative mortality. Eight (16%) patients developed complications of all grades, of which 2 (4%) were Grade 3 or higher, including anastomotic leakage (2%) and conversion to open surgery (2%). The present study demonstrates the feasibility and safety of robotic rectal cancer surgery, as reflected by low morbidity and low conversion rates, during the introduction period. © The Author 2017.

BACKGROUND: This article reports on patient-reported sexual dysfunction and micturition symptoms following a randomized trial of laparoscopic and open surgery for rectal cancer. METHODS: Patients in the COLOR II randomized trial, comparing laparoscopic and open surgery for rectal cancer, completed...... laparoscopic and open approaches. An improvement in sexual dysfunction was seen in the first year, but some male sexual problems persisted. Before operation 64·5 per cent of men in the laparoscopic group and 55·6 per cent in the open group reported some degree of erectile dysfunction. This increased to 81...... radiotherapy, did not change these results. CONCLUSION: Sexual dysfunction is common in patients with rectal cancer, and treatment (including surgery) increases the proportion of patients affected. A laparoscopic approach does not change this.

The late postoperative complications in patients after gastrectomy include anemia and metabolic bone disorders. We studied to determine whether gastric surgery is associated with metabolic bone disease. Vertebral BMD was measured in 55 patients after gastric resection by using DEQCT (dual energy quantitative CT). Forty patients were symptomatic, having bone or joint pain, history of bone fracture, or dental caries. The control group consisted of 161 patients without metabolic bone disorders. Forty percent of the patients with either the symptoms or history of bone fracture or dental caries, and 20% of the patients without the symptoms or the history showed decreased BMD. BMD was significantly lower in males in their 60s and in females in their 50s and 70s than BMD in age-matched control groups. When male subjects were grouped according to the years following the operation (1-5, 6-10, 11-15, 16-20 years), BMD was found to be decreased in 27%, 29%, 40% and 50% of the patients in each group, respectively, and the degree of the decrease tended to be greater with increasing time after surgery. Higher incidence of decreased BMD was found in the patients after total gastrectomy when compared with those after subtotal gastrecotmy. Among the patients with subtotal gastrectomy, the incidence of decreased BMD was higher in patients with Billroth II anastomosis than in those with Billroth I anastomosis. In cases with compression fracture on thoracolumbar radiographs, BMD was significantly lower in comparison with cases with no fracture. It was difficult to differentiate between osteomalacia and osteoporosis only by the thoracolumbar radiographs. While the clinical information such as patients' complaints, histories of fracture and laboratory findings are important to evaluate the bone changes following gastric resection. BMD measurement is most useful in quantitatively determining the degree of bone loss after gastrectomy. (author)

Labral repair and biceps tenodesis are routine operations for superior labrum anterior posterior (SLAP) lesion of the shoulder, but evidence of their efficacy is lacking. We evaluated the effect of labral repair, biceps tenodesis and sham surgery on SLAP lesions. A double-blind, sham-controlled trial was conducted with 118 surgical candidates (mean age 40 years), with patient history, clinical symptoms and MRI arthrography indicating an isolated type II SLAP lesion. Patients were randomly assigned to either labral repair (n=40), biceps tenodesis (n=39) or sham surgery (n=39) if arthroscopy revealed an isolated SLAP II lesion. Primary outcomes at 6 and 24 months were clinical Rowe score ranging from 0 to 100 (best possible) and Western Ontario Shoulder Instability Index (WOSI) ranging from 0 (best possible) to 2100. Secondary outcomes were Oxford Instability Shoulder Score, change in main symptoms, EuroQol (EQ-5D and EQ-VAS), patient satisfaction and complications. There were no significant between-group differences at any follow-up in any outcome. Between-group differences in Rowe scores at 2 years were: biceps tenodesis versus labral repair: 1.0 (95% CI -5.4 to 7.4), p=0.76; biceps tenodesis versus sham surgery: 1.6 (95% CI -5.0 to 8.1), p=0.64; and labral repair versus sham surgery: 0.6 (95% CI -5.9 to 7.0), p=0.86. Similar results-no differences between groups-were found for WOSI scores. Postoperative stiffness occurred in five patients after labral repair and in four patients after tenodesis. Neither labral repair nor biceps tenodesis had any significant clinical benefit over sham surgery for patients with SLAP II lesions in the population studied.

In patients with high risk stage II and stage III colon cancer (CC), curative surgery followed by adjuvant FOLFOX-4 chemotherapy has become the standard of care. However, for 20 to 30% of these patients, the current curative treatment strategy of surgical excision followed by adjuvant chemotherapy fails either to clear locoregional spread or to eradicate distant micrometastases, leading to disease recurrence. Preoperative chemotherapy is an attractive concept for these CCs and has the potential to impact upon both of these causes of failure. Optimum systemic therapy at the earliest possible opportunity may be more effective at eradicating distant metastases than the same treatment given after the delay and immunological stress of surgery. Added to this, shrinking the primary tumor before surgery may reduce the risk of incomplete surgical excision, and the risk of tumor cell shedding during surgery. PRODIGE 22--ECKINOXE is a multicenter randomized phase II trial designed to evaluate efficacy and feasibility of two chemotherapy regimens (FOLFOX-4 alone and FOLFOX-4 + Cetuximab) in a peri-operative strategy in patients with bulky CCs. Patients with CC deemed as high risk T3, T4 and/or N2 on initial abdominopelvic CT scan are randomized to either colectomy and adjuvant chemotherapy (control arm), or 4 cycles of neoadjuvant chemotherapy with FOLFOX-4 (for RAS mutated patients). In RAS wild-type patients a third arm testing FOLFOX+ cetuximab has been added prior to colectomy. Patients in the neoadjuvant chemotherapy arms will receive postoperative treatment for 4 months (8 cycles) to complete their therapeutic schedule. The primary endpoint of the study is the histological Tumor Regression Grade (TRG) as defined by Ryan. The secondary endpoints are: treatment strategy safety (toxicity, primary tumor related complications under chemotherapy, peri-operative morbidity), disease-free and recurrence free survivals at 3 years, quality of life, carcinologic quality and

Sevoflurane, an inhalational hypotensive anesthetic agent with a vasodilatory property, has been commonly used as a single agent to induce hypotension and effectively decrease blood loss in orthognathic surgery. However, it is common for patients to receive other hypotensive anesthetic agents in combination with sevoflurane. The purpose of our retrospective cohort study is to investigate whether administering an additional hypotensive agent has greater effect at reducing mean arterial pressure (MAP), estimated blood loss (EBL) and surgery time during orthognathic surgery. 57 subjects, aged 0-89 of both genders, who underwent orthognathic surgery were investigated in this study. Each patient's anesthesia records were reviewed to record the following variables of interest: EBL, duration of surgery, and MAP reduction in %. 41 subjects were placed in Group I and they received sevoflurane alone. 16 subjects were placed in Group II and they received sevoflurane plus a "supportive" agent. These "supportive" agents were esmolol, labetalol, metoprolol, nicardipine, and dexmedetomidine. The significant differences between two groups were assessed by using ANCOVA and p surgery time. Subjects in Group II experienced a greater reduction in MAP during surgery than subjects in Group I, 27.30% and 20.44%, respectively (p = 0.027). There was no significant difference for sex (p = 0.417) or age group (p = 0.113) in estimated blood loss, however. The mean surgery time in Group I was 1.93, 2.77, and 4.54 h with respect to LeFort, BSSO/IVRO, and double jaw surgery. Patients in Group II had a mean surgery time of 1.73, 2.07, and 5.64 h with respect to LeFort, BSSO/IVRO, and double jaw surgery. No statistically significant difference was demonstrated in surgery time between Group I vs. Group II (p > 0.05). Subjects in Group II experienced, on average, more blood loss than subjects in Group I, 355.50 ml and 238.90 ml, respectively. The use of multi-drug combination may offer

These studies were conducted to determine the relationship between quantitative tumor gene expression and risk of cancer recurrence in patients with stage II or III colon cancer treated with surgery alone or surgery plus fluorouracil (FU) and leucovorin (LV) to develop multigene algorithms to quantify the risk of recurrence as well as the likelihood of differential treatment benefit of FU/LV adjuvant chemotherapy for individual patients. We performed quantitative reverse transcription polymerase chain reaction (RT-qPCR) on RNA extracted from fixed, paraffin-embedded (FPE) tumor blocks from patients with stage II or III colon cancer who were treated with surgery alone (n = 270 from National Surgical Adjuvant Breast and Bowel Project [NSABP] C-01/C-02 and n = 765 from Cleveland Clinic [CC]) or surgery plus FU/LV (n = 308 from NSABP C-04 and n = 508 from NSABP C-06). Overall, 761 candidate genes were studied in C-01/C-02 and C-04, and a subset of 375 genes was studied in CC/C-06. A combined analysis of the four studies identified 48 genes significantly associated with risk of recurrence and 66 genes significantly associated with FU/LV benefit (with four genes in common). Seven recurrence-risk genes, six FU/LV-benefit genes, and five reference genes were selected, and algorithms were developed to identify groups of patients with low, intermediate, and high likelihood of recurrence and benefit from FU/LV. RT-qPCR of FPE colon cancer tissue applied to four large independent populations has been used to develop multigene algorithms for estimating recurrence risk and benefit from FU/LV. These algorithms are being independently validated, and their clinical utility is being evaluated in the Quick and Simple and Reliable (QUASAR) study.

Although maxillomandibular advancement (MMA) is an orthognathic surgical procedure used to manage obstructive sleep apnea (OSA) in individuals who are noncompliant with continuous positive airway pressure therapy, simple MMA encounters problems in terms of aesthetic outcomes in Asian populations with preexisting dentoalveolar protrusion. Our current prospective investigation describes changes in posterior pharyngeal space and aesthetic outcomes after counterclockwise rotational orthognathic surgery, which is known to be quite difficult in terms of the maintenance of the skeletal stability in skeletal class II patients with OSA. This prospective study investigated the surgical outcome of patients who suffered from OSA following counterclockwise rotational orthognathic surgery. The patients were skeletal class II patients who underwent orthognathic surgery between March 2013 and December 2014. Cephalometric posterior airway analysis and a questionnaire for facial perception were used to assess pharyngeal airway and patient perception of facial appearance. A total of 14 patients were included. Satisfactory results were achieved without complications in all OSA patients. The airway parameters for anteroposterior length significantly increased. Thirteen patients answered a questionnaire on their facial appearance, and the visual analog scale averaged 7.31 points, indicating a favorable facial appearance. Counterclockwise rotational orthognathic surgery without maxilla advancement for the correction of OSA can effectively increase the posterior pharyngeal space, with favorable aesthetic results. With thoughtful application, this novel approach may be an alternative to standard approaches for the correction of OSA using orthognathic surgery.

In patients with high risk stage II and stage III colon cancer (CC), curative surgery followed by adjuvant FOLFOX-4 chemotherapy has become the standard of care. However, for 20 to 30 % of these patients, the current curative treatment strategy of surgical excision followed by adjuvant chemotherapy fails either to clear locoregional spread or to eradicate distant micrometastases, leading to disease recurrence. Preoperative chemotherapy is an attractive concept for these CCs and has the potential to impact upon both of these causes of failure. Optimum systemic therapy at the earliest possible opportunity may be more effective at eradicating distant metastases than the same treatment given after the delay and immunological stress of surgery. Added to this, shrinking the primary tumor before surgery may reduce the risk of incomplete surgical excision, and the risk of tumor cell shedding during surgery. PRODIGE 22 - ECKINOXE is a multicenter randomized phase II trial designed to evaluate efficacy and feasibility of two chemotherapy regimens (FOLFOX-4 alone and FOLFOX-4 + Cetuximab) in a peri-operative strategy in patients with bulky CCs. Patients with CC deemed as high risk T3, T4 and/or N2 on initial abdominopelvic CT scan are randomized to either colectomy and adjuvant chemotherapy (control arm), or 4 cycles of neoadjuvant chemotherapy with FOLFOX-4 (for RAS mutated patients). In RAS wild-type patients a third arm testing FOLFOX+ cetuximab has been added prior to colectomy. Patients in the neoadjuvant chemotherapy arms will receive postoperative treatment for 4 months (8 cycles) to complete their therapeutic schedule. The primary endpoint of the study is the histological Tumor Regression Grade (TRG) as defined by Ryan. The secondary endpoints are: treatment strategy safety (toxicity, primary tumor related complications under chemotherapy, peri-operative morbidity), disease-free and recurrence free survivals at 3 years, quality of life, carcinologic quality and

Model surgery is an integral part of the planning procedure in orthognathic surgery. Most concepts comprise cutting the dental cast off its socket. The standardized spacer plates of the KD-MMS provide for a non-destructive, reversible and reproducible means of maxillary and/or mandibular plaster cast separation. In the course of development of the system various articulator types were evaluated with regard to their capability to provide a means of realizing the concepts comprised of the KD-MMS. Special attention was dedicated to the ability to perform three-dimensional displacements without cutting of plaster casts. Various utilities were developed to facilitate maxillary displacement in accordance to the planning. Objectives of this development comprised the ability to implement the values established in the course of two-dimensional ceph planning. The system - KD-MMS comprises a set of hardware components as well as a defined procedure. Essential hardware components are red spacer and blue mounting plates. The blue mounting plates replace the standard yellow SAM mounting elements. The red spacers provide for a defined leeway of 8 mm for three-dimensional movements. The non-destructive approach of the KD-MMS makes it possible to conduct different model surgeries with the same plaster casts as well as to restore the initial, pre-surgical situation at any time. Thereby, surgical protocol generation and gnathologic splint construction are facilitated. The KD-MMS hardware components in conjunction with the defined procedures are capable of increasing efficiency and accuracy of model surgery and splint construction. In cases where different surgical approaches need to be evaluated in the course of model surgery, a significant reduction of chair time may be achieved.

Diospyrobezoar as a Cause of Small Bowel Obstruction

Full Text Available Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki. We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel obstruction. The patient had a previous history of Billroth II hemigastrectomy associated with truncal vagotomy to treat a chronic duodenal ulcer 14 years earlier. Since intestinal obstruction was suspected, he underwent emergency laparotomy that revealed an ileal obstruction with small bowel perforation and local peritonitis due to a phytobezoar that was impacted 15 cm above the ileocecal valve. After segmental intestinal resection, the patient had a good recovery and was discharged on the 6th postoperative day. This report provides evidence that diospyrobezoar should be considered as a possible cause of small bowel obstruction in patients who have previously undergone gastric surgery.

Studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) anastomosis are still lacking and inconsistent. The aim of this trial was to compare the quality of life (QoL) of B-I with R-Y reconstruction after curative distal gastrectomy for gastric cancer. A total of 140 patients were randomly assigned to the B-I group (N = 70) and R-Y group (N = 70) with the comparable baseline characteristics. The overall postoperative morbidity rates were 18.6% and 25.7% in the B-I group and R-Y group without significant difference. More estimated blood loss and longer surgical duration were found in the R-Y group. At the postoperative 1 year time point, the B-I group had a higher score in pain, but lower score in global health. However, the R-Y anastomosis was associated with lower incidence of reflux symptoms at postoperative 6 months (P = 0.002) and postoperative 9 months (P = 0.007). The multivariable analyses of variance did not show any interactions between the time trend and grouping. For the results of endoscopic examination, the degree and extent of remnant gastritis were milder significantly in the R-Y group. The stronger anti-reflux capability of R-Y anastomosis contributes to the higher QoL by reducing the reflux related gastritis and pain symptoms, and promotes a better global health.

Perspectives and reflections on integrated digestive surgery.

2002-12-01

The history of the integration of surgery is both extensive and complex involving internecine machinations that have, over time, variously encompassed the alchemical, religious, technological and biological phases of societal development. Thus, the discipline has evolved from a mystic rite through a guild phase to its current eristic status as a therapeutic modality considered by some as an art form as opposed to a quasi-scientific endeavour of often unpredictable beneficial effect. This brief prolepsis provides an exposition of the evolution of surgeons and surgical thought proceeding from Galen in 3rd century Rome through Paré of Renaissance France, Billroth of fin de siècle Vienna, to Kocher and Whipple of Bern and New York respectively. It is apparent that in surgery, ontogeny may not readily recapitulate phylogeny and thus the need for a contemporary revaluation of integration within a novel educational nexus that encompasses the burgeoning matrix of biotechnological, ethical and fiduciary revolution is a critical requirement. Such an exercise must embody contemporary scientific and educational advance with evolving societal goals that include ethical variances, fiduciary issues and alterations in individual perceptions of life quality at both the medical and personal level. An incorporation of the basic tenets of digestive surgery as well as a delineation of its potential direction is both a vital and necessary exercise to ensure the attainment of appropriate future goals of medical, ethical, societal, scientific and educational validity. Current medical and surgical training programmes and the sub-specialization system are archaic, cumbersome, cost ineffective and, for the most part, represent endless computations and permutations of intellectually antiquated and stultifying processes designed more than a hundred years ago. As such, the maieutic skills as well as the clinical vista available for the delivery of visceral disease care bear little relation to

METHODS: The rats were submitted to partial gastrectomy (Billroth II or laparotomy (sham-operated control, in groups of 20 and 20 each respectively. The animals were fed with a control diet (AIN-93M without polydextrose or a diet containing polydextrose (50g/Kg of diet for eight weeks. They were divided into four subgroups: sham-operated and Billroth II gastrectomy and with or without polydextrose. Two animals died during the experiment. All rats submitted to gastrectomy received B-12 vitamin (intramuscular each two weeks. The hematocrit and hemoglobin concentration were measured at the start and on day 30 and 56 after the beginning of the experimental period. At the end of the study, the blood was collected for determination of serum iron concentration. RESULTS: The diet with polydextrose reduced the excretion of iron. Apparent iron absorption was higher in the polydextrose fed groups than in the control group. The haematocrit and haemoglobin concentration were lower after Billroth II gastrectomy rats fed the control diet as compared to the polydextrose diet groups.

Type II thyroplasty, or laryngeal framework surgery, is based on the hypothesis that the effect of adductor spasmodic dysphonia (AdSD) on the voice is due to excessively tight closure of the glottis, hampering phonation. Most of the previous, partially effective treatments have aimed to relieve this tight closure, including recurrent laryngeal nerve section or avulsion, extirpation of the adductor muscle, and botulinum toxin injection, which is currently the most popular. The aim of this study was to assess the effects of type II thyroplasty on aerodynamic and acoustic findings in patients with AdSD. Case series. University hospital. Ten patients with AdSD underwent type II thyroplasty between August 2006 and December 2008. Aerodynamic and acoustic analyses were performed prior to and six months after surgery. Mean flow rates (MFRs) and voice efficiency were evaluated with a phonation analyzer. Jitter, shimmer, the harmonics-to-noise ratio (HNR), standard deviation of the fundamental frequency (SDF0), and degree of voice breaks (DVB) were measured from each subject's longest sustained phonation sample of the vowel /a/. Voice efficiency improved significantly after surgery. No significant difference was found in the MFRs between before and after surgery. Jitter, shimmer, HNR, SDF0, and DVB improved significantly after surgery. Treatment of AdSD with type II thyroplasty significantly improved aerodynamic and acoustic findings. The results of this study suggest that type II thyroplasty provides relief from voice strangulation in patients with AdSD.

Robotic surgery is increasingly used to resect lung cancer. However costs are high. We compared costs and outcomes for robotic surgery, video-assisted thoracic surgery (VATS), and open surgery, to treat non-small cell lung cancer (NSCLC). We retrospectively assessed 103 consecutive patients given lobectomy or segmentectomy for clinical stage I or II NSCLC. Three surgeons could choose VATS or open, the fourth could choose between all three techniques. Between-group differences were assessed by Fisher's exact, two-way analysis of variance (ANOVA), and Wilcoxon-Mann-Whitney test. P values open surgery. Age, physical status, pulmonary function, comorbidities, stage, and perioperative complications did not differ between the groups. Pathological tumor size was greater in the open than VATS and robotic groups (P=0.025). Duration of surgery was 150, 191 and 116 minutes, by robotic, VATS and open approaches, respectively (Popen groups. Estimated costs were 82%, 68% and 69%, respectively, of the regional health service reimbursement for robotic, VATS and open approaches. Robotic surgery for early lung cancer was associated with shorter stay and more extensive lymph node dissection than VATS and open surgery. Duration of surgery was shorter for robotic than VATS. Although the cost of robotic thoracic surgery is high, the hospital makes a profit.

The purpose of this study was to identify factors that contribute to migraine headache surgery failure and success. A retrospective chart review was conducted of patients who underwent surgery for migraine headaches performed by the senior author (B.G.) and had at least 11 months of follow-up. The study population included three groups: migraine surgery success, improvement, and failure. Thirty-six unique data points were collected for each patient. A total of 169 patients met inclusion criteria. Of these, 66 patients comprised the migraine surgery success group (S, complete elimination of migraine headaches); 67 comprised the migraine surgery improvement group (I, >50 percent reduction in migraine frequency, intensity, or duration); and 36 comprised the migraine surgery failure group (F, I, p=0.02), migraine frequency (SI, p=0.003; S>F, p=0.04), history of head or neck injury (SI, p=0.02), increased intraoperative bleeding (SF, p=0.0006; I>F, p=0.0004), site II (S>F, p=0.015), single operative site (SI, p=0.05; S>F, p=0.04). Factors associated with migraine surgery failure include increased intraoperative bleeding and surgery on fewer trigger sites. Factors associated with migraine surgery success are older age of migraine onset, higher rate of visual symptoms versus improvement group, surgery at site I or II, and deactivating all four operative sites.

Full Text Available Purpose: This study aimed to evaluate the changes in macular thickness following inferior oblique muscle recession surgery. Materials and Methods: Thirty-eight eyes from 21 patients undergoing ocular muscle surgery were included. Patients were grouped into three groups based on the type of surgical intervention: Group I (n = 12, inferior oblique recession surgery alone; Group II (n = 12, inferior oblique plus horizontal muscle surgery; Group III (n = 14, horizontal muscle surgery alone. Each eye was scanned using the optical coherence tomography (OCT device preoperatively and on the first postoperative day to measure macular thickness. Results: Following surgery, a significant increase in foveal thickness occurred in Group I (P < 0.05 and Group II (P < 0.01. In addition, a statistically significant difference was observed between the groups with regard to the increase in foveal thickness (P = 0.016, with significantly lower changes in Group III. Conclusion: Our findings suggested that inferior oblique muscle recession surgery is associated with an increase in macular thickness.

Full Text Available Obesity is increasing globally and represents a significant global health problem because it predisposes towards various diseases, such as type 2 diabetes mellitus, cardiovascular disease, degenerative joint disease, and certain types of cancer. Numerous studies have shown that bariatric surgery reduces body mass and ameliorates obesity-related complications, such as hypertension and hyperglycemia, suggesting that surgery is the most effective therapeutic option for severely obese and obese diabetic patients. Recent international guidelines recommend surgical treatment for diabetic patients with class III obesity (body mass index [BMI] >40 kg/m2, regardless of their level of glycemic control or the complexity of their glucose-lowering regimens, and for patients with class II obesity (BMI 35.0 to 39.9 kg/m2 and hyperglycemia that is poorly controlled despite appropriate lifestyle and pharmacological therapy. The most popular procedures are Roux-en-Y gastric bypass and sleeve gastrectomy, but new procedures with better outcomes have been reported. For optimal surgical outcome, comprehensive management including assessments of a medical condition, nutrition, mental health, and social support is needed before and after surgery. However, there is still a lack of understanding regarding metabolic surgery in Korea. Therefore, this article reviews indications for metabolic surgery in patients with a specific focus on the situation in Korea.

Full Text Available Background and Aim. Perforation after endoscopic retrograde cholangiopancreatography (ERCP is a rare complication, but it is associated with significant mortality. This study evaluated the early management experience of these perforations. Patients and Methods. Between November 2003 and December 2011, a total of 8504 ERCPs were performed at our regional endoscopy center. Sixteen perforations (0.45% were identified and retrospectively reviewed. Results. Nine of these 16 patients with perforations were periampullary, 3 duodenal, 1 gastric fundus, and 3 patients had a perforation of an afferent limb of a Billroth II anastomosis. All patients with perforations were recognized during ERCP by X-ray and managed immediately. One patient with duodenal perforation and three patients with afferent limb perforation received surgery, others received medical conservative treatment which included suturing lesion, endoscopic nasobiliary drainage (ENBD, endoscopic retrograde pancreatic duct drainage (ERPD, gastrointestinal decompression, fasting, broad-spectrum antibiotics, and so on. All patients with perforation recovered successfully. Conclusions. We found that: (1 the diagnosis of perforation during ERCP may be easy, but you must pay attention to it. (2 Most retroperitoneal perforations can recover with only medical conservative treatment in early phase. (3 Most peritoneal perforations need surgery unless you can close the lesion up under endoscopy in early phase.

The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II was developed to improve the overestimation of surgical risk associated with the original (additive and logistic) EuroSCOREs. The purpose of this study was to evaluate the significance of the EuroSCORE II by comparing its performance with that of the original EuroSCOREs in Japanese patients undergoing surgery on the thoracic aorta. We have calculated the predicted mortalities according to the additive EuroSCORE, logistic EuroSCORE and EuroSCORE II algorithms in 461 patients who underwent surgery on the thoracic aorta during a period of 20 years (1993-2013). The actual in-hospital mortality rates in the low- (additive EuroSCORE of 3-6), moderate- (7-11) and high-risk (≥11) groups (followed by overall mortality) were 1.3, 6.2 and 14.4% (7.2% overall), respectively. Among the three different risk groups, the expected mortality rates were 5.5 ± 0.6, 9.1 ± 0.7 and 13.5 ± 0.2% (9.5 ± 0.1% overall) by the additive EuroSCORE algorithm, 5.3 ± 0.1, 16 ± 0.4 and 42.4 ± 1.3% (19.9 ± 0.7% overall) by the logistic EuroSCORE algorithm and 1.6 ± 0.1, 5.2 ± 0.2 and 18.5 ± 1.3% (7.4 ± 0.4% overall) by the EuroSCORE II algorithm, indicating poor prediction (P algorithms were 0.6937, 0.7169 and 0.7697, respectively. Thus, the mortality expected by the EuroSCORE II more closely matched the actual mortality in all three risk groups. In contrast, the mortality expected by the logistic EuroSCORE overestimated the risks in the moderate- (P = 0.0002) and high-risk (P < 0.0001) patient groups. Although all of the original EuroSCOREs and EuroSCORE II appreciably predicted the surgical mortality for thoracic aortic surgery in Japanese patients, the EuroSCORE II best predicted the mortalities in all risk groups.

Although bariatric surgery has become a recognized treatment for obesity, its utility among patients with severe psychiatric disorders has not been extensively studied. A few studies have reported similar weight loss outcomes in these patients, but psychiatric status after bariatric surgery has been studied only minimally, and it is unknown if exacerbation of the mental illness affects weight loss. The aim of this study was to shed greater light on the issue of serious mental illness and bariatric surgery. Specifically, do patients with a diagnosis of schizophrenia, bipolar I, and bipolar II have poorer weight loss outcomes postbariatric surgery than the general bariatric surgery population? Also, do patients with these diagnoses experience an exacerbation of psychiatric symptoms after bariatric surgery, and if so, is the exacerbation of these disorders linked to poorer weight loss results? Midwest university medical center. A medical record review of approximately 1500 bariatric patients in a Midwest university medical center was conducted to identify those patients with diagnoses of schizophrenia, bipolar I, and bipolar II. Information was gathered on bariatric surgery outcomes and changes in psychiatric status postsurgery. Eighteen patients were identified as undergoing bariatric surgery and having a diagnosis of schizophrenia, bipolar I, or bipolar II. Weight loss in this group was significant and comparable to expected outcomes of absolute weight lost, changes in body mass index, and percentage excess weight loss for patients in the typical bariatric population. Postsurgery psychiatric status was known on 10 patients. All 10 patients experienced some exacerbation of psychiatric problems yet weight loss outcomes were still as expected. Bariatric surgery is a viable obesity treatment option for patients with schizophrenia, bipolar I, and bipolar II disorders. Symptom exacerbations occurred postsurgery, although it is not clear if these were due to the surgery or

The European System for Cardiac Operative Risk Evaluation (EuroSCORE) has been established as a tool for assisting decision-making in surgical patients and as a benchmark for quality assessment. Infective endocarditis often requires surgical treatment and is associated with high mortality. This study was undertaken to (i) validate both versions of the EuroSCORE, the older logistic EuroSCORE I and the recently developed EuroSCORE II and to compare their performances; (ii) identify predictors other than those included in the EuroSCORE models that might further improve their performance. We retrospectively studied 128 patients from a single-centre registry who underwent heart surgery for active infective endocarditis between January 2007 and November 2014. Binary logistic regression was used to find independent predictors of mortality and to create a new prediction model. Discrimination and calibration of models were assessed by receiver-operating characteristic curve analysis, calibration curves and the Hosmer-Lemeshow test. The observed perioperative mortality was 16.4% (n = 21). The median EuroSCORE I and EuroSCORE II were 13.9% interquartile range (IQ) (7.0-35.0) and 6.6% IQ (3.5-18.2), respectively. Discriminative power was numerically higher for EuroSCORE II {area under the curve (AUC) of 0.83 [95% confidence interval (CI), 0.75-0.91]} than for EuroSCORE I [0.75 (95% CI, 0.66-0.85), P = 0.09]. The Hosmer-Lemeshow test showed good calibration for EuroSCORE II (P = 0.08) but not for EuroSCORE I (P = 0.04). EuroSCORE I tended to over-predict and EuroSCORE II to under-predict mortality. Among the variables known to be associated with greater infective endocarditis severity, only prosthetic valve infective endocarditis remained an independent predictor of mortality [odds ratio (OR) 6.6; 95% CI, 1.1-39.5; P = 0.04]. The new model including the EuroSCORE II variables and variables known to be associated with greater infective endocarditis severity showed an AUC of 0

Abdominal Non-Hodgkin lymphomas (NHL) are the most common extra nodal presentation of pediatric NHL. Our aim is to assess the role of surgery as a risk factor and to evaluate the impact of risk-adjusted systemic chemotherapy on survival of patients with stages II and III disease. This study included 35 pediatric patients with abdominal NHL treated over five years at South Egypt Cancer Institute (SECI), Assiut University, between January 2005 and January 2010. The data of every patient included: Age, sex, and presentation, staging work up to determine extent of the disease and the type of resection performed, histopathological examination, details of chemotherapy, disease free survival and overall survival. The study included 25 boys and 10 girls with a median age of six years (range: 2.5:15). Thirty patients (86%) presented with abdominal pain, 23 patients (66%) presented with abdominal mass and distention, 13 patients (34%) presented with weight loss, and intestinal obstruction occurred in six patients (17%). The ileo-cecal region and abdominal lymph nodes were the commonest sites (48.5%, 21% respectively). Burkitt's lymphoma was the most common histological type in 29 patients (83%). Ten (28.5%) stage II (group A) and 25 (71.5%) stage III (group B). Complete resections were performed in 10 (28.5%), debulking in 6 (17%) and imaging guided biopsy in 19 (54%). A11 patients received systemic chemotherapy. The median follow up duration was 63 months (range 51-78 months). The parameters that significantly affect the overall survival were stage at presentation complete resection for localized disease. In conclusion, the extent of disease at presentation is the most important prognostic factor in pediatric abdominal NHL. Surgery is restricted to defined situations such as; abdominal emergencies, diagnostic biopsy and total tumor extirpation in localized disease. Chemotherapy is the cornerstone in the management of pediatric abdominal NHL.

2010-01-01

Purpose: The goal of this study was to determine the role of radiotherapy after curative-intent surgery in the management of extrahepatic bile duct (EHBD) cancers. Methods and Materials: From 1997 through 2005, 78 patients with EHBD cancer were surgically staged. These patients were stratified by the absence of adjuvant radiation (n = 47, group I) versus radiation (n = 31, group II) after resection. Pathology examination showed 27 cases in group I and 20 cases in group II had microscopically positive resection margins. The patients in group II received 45 to 54 Gy of external beam radiotherapy. The primary endpoints of this study were overall survival, disease-free survival, and prognostic factors. Results: There were no differences between the 5-year overall survival rates for the two groups (11.6% in group I vs. 21% in group II). However, the patients with microscopically positive resection margins who received adjuvant radiation therapy had higher median disease-free survival rates than those who underwent surgery alone (21 months vs. 10 months, respectively, p = 0.042). Decreasing local failure was found in patients who received postoperative radiotherapy (61.7% in group I and 35.6% in group II, p = 0.02). Outcomes of the patients with a positive resection margin and lymph node metastasis who received postoperative radiation therapy were doubled compared to those of patients without adjuvant radiotherapy. Resection margin status, lymph node metastasis, and pathology differentiation were significant prognostic factors in disease-free survival. Conclusions: Adjuvant radiotherapy might be useful in patients with EHBD cancer, especially for those patients with microscopic residual tumors and positive lymph nodes after resection for increasing local control.

There has been considerable debate on the cost-effectiveness of bariatric surgery within larger population groups. Despite the recognition that morbid obesity and its comorbidities are best treated surgically, insurance coverage is not universally available. One of the more costly comorbidities of obesity is Type II diabetes mellitus (T2DM). We propose a model that demonstrates the cost-effectiveness of increasing the number of bariatric surgical operations performed on patients with T2DM in the United States. We applied published population cost estimates (2012) for medical care of T2DM to a retrospective cohort of morbidly obese patients in South Carolina. We compared differences in 10-year medical costs between those having bariatric surgery and controls. Resolution of T2DM in the bariatric cohort was assumed to be 40 per cent. Considering only the direct medical costs of T2DM, the 10-year aggregate cost savings compared with a control group is $2.7 million/1000 patients; the total (direct and indirect) cost savings is $5.4 million/1000 patients. When considering resolution of T2DM alone, increasing the number of bariatric operations for a given population leads to a substantial cost savings over a 10-year period. This study adds to the growing body of evidence suggesting that bariatric surgery is a cost-effective means of caring for the obese patient.

The purpose of this paper is to present a long- term electroclinical and employment follow up in temporal lobe epilepsy (TLE) patients in a comprehensive epilepsy surgery program. Forty adult patients with pharmacoresistant TLE underwent detailed presurgical evaluation. Electroencephalogram (EEG) and clinical follow up assessment for each patient were carried out. The occurrence of interictal epileptiform activity (IEA) and absolute spike frequency (ASF) were tabulated before and after 1, 6, 12, 24 and 72 months surgical treatment. Employment status pre- to post-surgery at the last evaluated period was also examined. Engel scores follow-up was described as follows: at 12 months 70% (28) class I, 10% (4) class II and 19% (8) class III-IV; at 24 months after surgery 55.2% (21) of the patients were class I, 28.9% (11) class II and 15.1% (6) class III-IV. After one- year follow up 23 (57.7%) patients were seizure and aura-free (Engel class IA). These figures changed to 47.3%, and 48.6% respectively two and five years following surgery whereas 50% maintained this condition in the last follow up period. A decline in the ASF was observed from the first year until the sixth year after surgery in relation to the preoperative EEG. The ASF one year after surgery allowed to distinguish “satisfactory” from “unsatisfactory” seizure relief outcome at the last follow up. An adequate social functioning in terms of education and employment in more than 50% of the patients was also found. Results revealed the feasibility of conducting a successful epilepsy surgery program with favorable long term electroclinical and psychosocial functioning outcomes in a developing country as well.

To find out the occurrence of postoperative nausea and vomiting (PONY) in oral and maxillofacial surgery done under general anaesthesia and to evaluate the purpose of using prophylactic antiemetic drugs. Design: Observational study. Place and Duration of the Study: Oral and Maxillofacial Department, KEMU / Mayo Hospital Lahore, from September 20 II to June 2012. Method: The number of patients who were operated in oral and maxillofacial surgery ward irrespective of age and gender for this study were 240. Risk factors related with PONY including gender, anesthetic drug used, surgical procedure, approach' used, total time of surgery and postoperative use of opioids were investigated. A wait and watch scheme was followed in patients with complaint of PONY. Antiemetics to be given in those cases where more than 2 episodes of vomiting took place. Results: It was found out that only II patients experienced from nausea and vomiting in post operative period. A notable relation was seen between PONY and female population, total time of surgery, anesthetic drug, surgery of tumor and temporomandibular joint. The surgical approach and opioids in postoperative period for PONY were found to be insignificant. Conclusion: PONY is not a significant finding in oral and maxillofacial surgery. We find out that there is no logic for the use of prophylactic antiemetic drugs in maxillofacial surgery. (author)

The aim of this study was to determine the ability of undenatured native chicken type II collagen (UC-II) to prevent excessive articular cartilage deterioration in a rat model of osteoarthritis (OA). Twenty male rats were subjected to partial medial meniscectomy tear (PMMT) surgery to induce OA. Immediately after the surgery 10 rats received vehicle and another 10 rats oral daily dose of UC-II at 0.66 mg/kg for a period of 8 weeks. In addition 10 naïve rats were used as an intact control and another 10 rats received sham surgery. Study endpoints included a weight-bearing capacity of front and hind legs, serum biomarkers of bone and cartilage metabolism, analyses of subchondral and cancellous bone at the tibial epiphysis and metaphysis, and cartilage pathology at the medial tibial plateau using histological methods. PMMT surgery produced moderate OA at the medial tibial plateau. Specifically, the deterioration of articular cartilage negatively impacted the weight bearing capacity of the operated limb. Immediate treatment with the UC-II preserved the weight-bearing capacity of the injured leg, preserved integrity of the cancellous bone at tibial metaphysis and limited the excessive osteophyte formation and deterioration of articular cartilage. Study results demonstrate that a clinically relevant daily dose of UC-II when applied immediately after injury can improve the mechanical function of the injured knee and prevent excessive deterioration of articular cartilage.

Background and purpose: To evaluate whether preoperative hyperfractionated accelerated radiotherapy (RT) combined with major radical surgery is feasible and successful in the treatment of advanced primary head and neck cancer. Patients and methods: Ninety four patients with histologically confirmed head and neck squamous cell cancer (HNSCC) in the oral cavity (41/96; 43%), supraglottis (14/96; 15%), glottis (5/96; 5%), oropharynx (16/96; 17%), nasal cavity/paranasal sinuses (8/96; 8%), nasopharynx (3/96; 3%), hypopharynx (7/96; 7%) and two (2%) with unknown primary tumour and large cervical lymph nodes entered into the study. 21/96 patients (22%) had stage II, 17/96 (18%) stage III and 58/96 patients (60%) stage IV disease. The patients received preoperative hyperfractionated RT 1.6 Gy twice a day, 5 days a week to a median tumour dose of 63 Gy with a planned break for 11 days (median) after the median dose of 37 Gy. Then, after a median of 27 days the patients underwent major radical surgery of the primary tumour and metastatic lymph nodes including reconstructions with pedicled or microvascular free flaps when indicated as a part of the scheduled therapy. 12/96 patients had only ipsilateral or bilateral neck dissections. Results: After a median follow-up time of 37.2 mos 77/96 (80.2%) patients had complete locoregional control. All but 2 patients had complete histological remission after surgery. 40/96 pts were alive without disease, two of them after salvage surgery. 32/96 patients had relapsed; 15 had locoregional and 13 distant relapses, 4 patients relapsed both locoregionally and distantly. Fifty patients have died; 29 with locoregional and/or distant relapse, eight patients died of second malignancy, and 19 had intercurrent diseases. Disease-specific and overall survival at 3 years was 67.7 and 51%, respectively. Acute grade three mucosal reactions were common, but transient and tolerable. Late grade 3-4 adverse effects were few.

This study primarily aimed to investigate the short- and long-term remission rates of type 2 diabetes (T2D) in patients who underwent surgical treatment for gastric cancer, especially patients who were non-obese, and secondarily to determine the potential factors associated with remission. We retrospectively reviewed the clinical records of patients with T2D who underwent radical gastrectomy for gastric cancer, from January 2008 to December 2012. T2D improved in 39 out of 70 (55.7%) patients at the postoperative 2-year follow-up and 21 of 42 (50.0%) at the 5-year follow-up. In the 2-year data analysis, preoperative body mass index (BMI) (P=0.043), glycated hemoglobin (A1C) level (P=0.039), number of anti-diabetic medications at baseline (P=0.040), reconstruction method (statistical difference was noted between Roux-en-Y reconstruction and Billroth I; P=0.035) were significantly related to the improvement in glycemic control. Unlike the results at 2 years, the 5-year data analysis revealed that only preoperative BMI (P=0.043) and A1C level (P=0.039) were statistically significant for the improvement in glycemic control; however, the reconstruction method was not. All types of gastric cancer surgery can be effective in short- and long-term T2D control in non-obese patients. In addition, unless long-limb bypass is considered in gastric cancer surgery, the long-term glycemic control is not expected to be different between the reconstruction methods.

Malignant pleural mesothelioma is an aggressive tumor that has a poor prognosis and is resistant to unimodal approaches. Multimodal treatment has provided encouraging results. Phase II, open-label study of the combination of chemotherapy (pemetrexed 500 mg/m 2 +cisplatin 75 mg/m 2 IV every 21 days × 3 cycles), followed by surgery (en-bloc extrapleural pneumonectomy, 3–8 weeks after chemotherapy) and hemithoracic radiation (total radiation beam 54 Gy, received 4–8 weeks post-surgery). The primary endpoint was event-free survival, defined as the time from enrollment to time of first observation of disease progression, death due to any cause, or early treatment discontinuation. Fifty-four treatment-naïve patients with T1-3 N0-2 malignant pleural mesothelioma were enrolled, 52 (96.3%) completed chemotherapy, 45 (83.3%) underwent surgery, 22 (40.7%) completed the whole treatment including 90-day post-radiation follow-up. The median event-free survival was 6.9 months (95%CI: 5.0-10.5), median overall survival was 15.5 months (95%CI 11.0-NA) while median time-to-tumor response was 4.8 months (95%CI: 2.5-8.0). Eighteen (33.3%) and 13 (24.1%) patients were still event-free after 1 and 2 years, respectively. The most common treatment-emergent adverse events were nausea (63.0%), anemia (51.9%) and hypertension (42.6%). Following two cardiopulmonary radiation-related deaths the protocol was amended (21 [38.9%] patients were already enrolled in the study): the total radiation beam was reduced from 54 Gy to 50.4 Gy and a more accurate selection of patients was recommended. The combination of pemetrexed plus cisplatin followed by surgery and hemithoracic radiation is feasible and has a manageable toxicity profile in carefully selected patients. It may be worthy of further investigation. Clinicaltrial.com registrationID #NCT00087698

Full Text Available The following article recommends guidelines for epilepsy surgery for India. This article reviews the indications, the various surgical options available and the outcome of surgery for drug resistant epilepsy based on current evidence. Epilepsy surgery is a well-established option for patients who have been diagnosed to have drug resistant epilepsy (DRE (on at least two appropriate, adequate anti-epileptic drugs (AEDs (either in monotherapy or in combination with continuing seizures, where the presurgical work-up has shown concordance of structural imaging (magnetic resonance imaging and electrical mapping data (electroencephalography (EEG, video EEG. There may be a requirement of functional imaging techniques in a certain number of DRE like positron emission tomography (PET, single photon emission tomography, (SPECT. Invasive monitoring should be restricted to a few when all noninvasive investigations are inconclusive, there is a dual pathology or there is a discordance of noninvasive data. The types of surgery could be curative (resective surgeries: amygdalo hippocampectomy, lesionectomy and multilobar resections; functional surgeries: hemispherotomy and palliative (multiple subpial transaction, corpus callosotomy, vagal nerve stimulation. Epilepsy surgery in indicated cases has a success range from 50 to 86% in achieving seizure freedom as compared with < 5% success rate with AEDs only in persons with DRE. Centers performing surgery should be categorized into Level I and Level II.

2011-01-01

The introduction of the Duke criteria and transesophageal echocardiography has improved early recognition of infective endocarditis but patients are still at high risk for severe morbidity or death. Whether an exclusively antibiotic regimen is superior to surgical intervention is subject to ongoing debate. Current guidelines indicate when surgery is the preferred treatment, but decisions are often based on physician preferences. Surgery has shown to decrease the risk of short-term mortality in patients who present with specific symptoms or microorganisms; nevertheless even then it often remains unclear when surgery should be performed. In this review we i) systematically reviewed the current literature comparing medical to surgical therapy to evaluate if surgery is the preferred option, ii) performed a meta-analysis of studies reporting propensity matched analyses, and iii), briefly summarized the current indications for surgery.

2013-01-01

Full Text Available Objectives: This study was conducted to evaluate the effect of tranexamic acid (TA on the intra-operative bleeding during the functional endoscopic sinus surgery (FESS in children. Methods: A total of 100 children recruited to undergo FESS were randomized into two groups. Group I: Was given just after induction, intra-venous 25 mg/kg TA diluted in 10 ml of normal saline. Group II: Was given 10 ml of normal saline. Non-invasive blood pressure, heart rate, and quality of the surgical field were estimated every 15 min. Volume of bleeding and duration of the surgical procedure were recorded. Results: Surgical field quality after 15 min revealed that seven patients in group I had minimal bleeding versus no one in group II, P=0.006. Meanwhile, 35 patients in group I had mild bleeding versus 26 patients in group II, P=0.064. Higher number of patients in group II than in group I had moderate bleeding, P=0006. Also, at 30 min, revealed that 10 patients in group I had minimal bleeding versus one patient in group II, P=0.004. Meanwhile, 37 patients in group I had mild bleeding versus 28 patients in group II, P=0.059. Higher number of patients in group II than in group I had moderate bleeding, P<0001. Duration of the surgeries and volume of bleeding were significantly less in tranexamic group than the placebo group, P<0.0001. Conclusion: Single intra-venous bolus dose of tranexamic in children during the FESS improves quality of surgical field, reduces intra-operative bleeding, and duration of surgery.

This study involved a retrospective evaluation of patients subjected to surgery for dentofacial deformities treated without induced controlled hypotension (group I, n=50) and a prospective evaluation of patients who were subjected to surgery under hypotensive general anaesthesia (group II, n=50). No statistical differences were found between the study groups with regard to the duration of surgery. However, there were statistically significant differences in the need for blood transfusion and the occurrence of bradycardia during the maxillary down-fracture. Hypotensive anaesthesia decreased the need for a blood transfusion and the occurrence of bradycardia, and is therefore considered highly beneficial for patients undergoing orthognathic surgery.

Fistula gastrocólica

Directory of Open Access Journals (Sweden)

Alexandre Cruz Henriques

Full Text Available A case of gastrocolic fistula(GCF in a patient with duodenal stenosis who had previously undergone gastroenteric anastomosis is reported. The patient went through hemigastrectomy, partial colectomy and segmental enterectomy with bloc resection. Reconstruction was carried out through Billroth II gastrojejunostomy, jejunojejunostomy and end-to-end anastomosis of the colon. The patient had good post-operative evolution and was discharged from hospital seven days after surgery. GCF should be suspected in patients presenting weight loss, diarrhea and fecal vomiting, mainly with history of peptic ulcer surgery, gastric or colonic malignancy and use of steroidal and nonsteroidal antiinflamatory drugs. Barium enema is the choice test for diagnosis, however, the benign or malignant nature of the lesion should always be evaluated through high digestive endoscopy. Clinical treatment with oral H2-antagonists and discontinuing ulcerogenic medications might be indicated in some cases; surgical treatment is indicated in cases of malignant disease and might be indicated in cases of peptic disease as it treats GCF and also the baseline disease. Some advise upwards colostomy at first. The most used technique is bloc resection, including the fistulous tract, hemigastrectomy and partial colectomy. Gastrectomy, fistulous tract excision and colon suturing may be performed in some cases. The mortality rate is related to metabolic disorders and the recurrence with the use of antiinflammatory drugs.

To study the relationship between cerebral oxygen saturation changes and postoperative neurologic complications. Seventy two adult patients with ASA class II, III who were scheduled for elective cardiac surgery, were randomized into three groups: Group I: with CPB (on -pump) Group II: without CPB (off- pump) Group III: valve surgery. Neuropsychological outcome was assessed by the Mini-Mental State Examination (MMSE). Cerebral oxygen saturation was also measured. There was no statistical difference in desaturation of more than 20% among three groups (P=0.113) but it was significant between group I and II (P=0.042). Changes of rSo/sub 2/ in different hours of surgery was significant in group I and group II (P=0.0001 in both) but it was not significant in group III ( P=0.075) . Although cerebral oximetry is a noninvasive and useful method of monitoring during cardiac surgery, it has low accuracy to determine postoperative neurologic complications. (author)

This study was designed to establish the essential hand surgery procedures that should be mastered by graduating plastic surgery residents. This framework can then be used as a guideline for developing Objective Structured Assessment of Technical Skill to teach technical skills in hand surgery. Ten expert hand surgeons were surveyed regarding the essential hand surgery procedures that should be mastered by graduating plastic surgery residents. The top 10 procedures from this survey were then used to survey all 89 Accreditation Council for Graduate Medical Education-approved plastic surgery program directors. There was a 69 percent response rate to the program director survey (n = 61). The top nine hand surgery procedures included open carpal tunnel release, open A1 pulley release, digital nerve repair with microscope, closed reduction and percutaneous pinning of metacarpal fracture, excision of dorsal or volar ganglion, zone II flexor tendon repair with multistrand technique, incision and drainage of the flexor tendon sheath for flexor tenosynovitis, flexor tendon sheath steroid injection, and open cubital tunnel release. Surgical educators need to develop objective methods to teach and document technical skill. The Objective Structured Assessment of Technical Skill is a valid method for accomplishing this task. There has been no consensus regarding which hand surgery procedures should be mastered by graduating plastic surgery residents. The authors have identified nine procedures that are overwhelmingly supported by plastic surgery program directors. These nine procedures can be used as a guideline for developing Objective Structured Assessment of Technical Skill to teach and document technical skills in hand surgery.

Many bariatric surgery programs require that candidates undergo a preoperative mental health evaluation. Candidates may be motivated to suppress or exaggerate psychiatric symptoms (i.e., engage in impression management), if they believe doing so will enhance their chances of receiving a recommendation to proceed with surgery. 237 candidates for bariatric surgery completed the Beck Depression Inventory-II (BDI-ll) as part of their preoperative psychological evaluation (Time 1). They also completed the BDI-II approximately 2-4 weeks later, for research purposes, after they had received the mental health professional's unconditional recommendation to proceed with surgery (Time 2). There was a small but statistically significant increase in mean BDI-II scores from Time 1 to Time 2 (11.4 vs 12.7, Ppsychological "clearance" for surgery. Possible explanations for these findings include measurement error, impression management, and true changes in psychiatric status.

Our study is a prospective, randomized study on patients undergoing arthroscopic shoulder surgery in the beach-chair position to evaluate the effects of positive end-expiratory pressure (PEEP) on hemodynamic stability, providing a bloodless surgical field and surgical satisfaction. Fifty patients were divided into two groups. Group I (n=25) had zero end-expiratory pressure (ZEEP) administered under general anesthesia, and group II (n=25) had +5 PEEP administered. During surgery, intraarticular hemorrhage and surgical satisfaction were evaluated on a scale of 0-10. During surgery, at the 5th, 30th, 60th, and 90th minutes and at the end of surgery, heart rate, mean arterial pressure (MAP), and positive inspiratory pressure were recorded. At the end of the surgery, the amount of bleeding and duration of the operation were recorded. In group I, the duration of operation and amount of bleeding were found to be significantly greater than those in group II (pshoulder surgery in the beach-chair position reduces the amount of hemorrhage in the surgical field and thus increases surgical satisfaction without requiring the creation of controlled hypotension.

Remnant gastric cancer, most frequently defined as cancer detected in the remnant stomach after distal gastrectomy for benign disease and those cases after surgery of gastric cancer at least 5 years after the primary surgery, is often reported as a tumor with poor prognosis. The Task Force of Japanese Gastric Cancer Association for Research Promotion evaluated the clinical impact of remnant gastric cancer by systematically reviewing publications focusing on molecular carcinogenesis, lymph node status, patient survival, and surgical complications. A systematic literature search was performed using PubMed/MEDLINE with the keywords "remnant," "stomach," and "cancer," revealing 1154 relevant reports published up to the end of December 2014. The mean interval between the initial surgery and the diagnosis of remnant gastric cancer ranged from 10 to 30 years. The incidence of lymph node metastases at the splenic hilum for remnant gastric cancer is not significantly higher than that for primary proximal gastric cancer. Lymph node involvement in the jejunal mesentery is a phenomenon peculiar to remnant gastric cancer after Billroth II reconstruction. Prognosis and postoperative morbidity and mortality rates seem to be comparable to those for primary proximal gastric cancer. The crude 5-year mortality for remnant gastric cancer was 1.08 times higher than that for primary proximal gastric cancer, but this difference was not statistically significant. In conclusion, although no prospective cohort study has yet evaluated the clinical significance of remnant gastric cancer, our literature review suggests that remnant gastric cancer does not adversely affect patient prognosis and postoperative course.

Postoperative antimicrobial therapy is generally administered as standard prophylaxis against postoperative infection, despite a lack of sufficient evidence for its usefulness. This study was a phase II study to evaluate the necessity of postoperative antibiotic prophylaxis in patients undergoing a colectomy. Patients received 1 g cefmetazole or flomoxef immediately after anesthetic induction, every 3 h during surgery, and then later once again on the next day. They were randomly assigned to receive either cefmetazole or flomoxef. Ninety-one patients were enrolled in the study. A surgical site infection (SSI) occurred in 7.7% (7/91) of patients. All cases were superficial incisional infections. When comparing the two drugs, SSI occurred in 8.3% (4/48) of patients treated with cefmetazole and in 7.0% (3/43) treated with flomoxef, showing no significant difference (P > 0.99). Antimicrobial prophylaxis was well tolerated when used on the day of a colectomy and once again on the next day.

before surgery. RESULTS: The final results show that most of the patients had very good and good clinical evolution (Visick I e II in 96%. The most common symptoms on late postoperative are mild dyspepsia with or without Helicobacter pylori, and diarrhea, anemia and dumping occurred in, respectively, 11 (18.6%, 2 (3.4% and 2 (3.4% cases. The Billroth I reconstruction had the best clinical results on statistical rate. The endoscopic finding showed normal results in the most number of cases, and reflux alkaline gastritis or erosive gastritis in a few cases. Ulcer recurrences were diagnosed in two patients (3.4%, and both had positive Helicobacter pylori. Most of the patients had Helicobacter pylori (86% before surgery and also in the postoperative time (89.9%. CONCLUSIONS: The patients had a very good clinical evolution after the gastrectomy. The Billroth I reconstruction had the best clinical results. The Helicobacter pylori is still present on gastric stump in late postoperative time, and we believe that it does not bring any negative influence to surgical results.

These interventions usually aimed at the correction of the skeletal discrepancy by mandibular retrognatism with an advancement of the distal portion of the mandible after mandibular osteotomy. The position of the condyle is determined during the osteosynthesis with miniplates. Condyles are set back in relation with the supine position of the patient and the weakness of his (her) curarized muscle. All studies show that surgery of mandibular advancement causes a lateral, torque and backward movement of the condyles, all harmful to the condyles. Factors that predispose to condylar resorption are "the patient": a woman, young (between 15 and 40), high mandibular angle, with a history of temporo-mandibular disorders and surgical overload applied to the condyles. What are the possible solutions to avoid failures? Patient preparation before surgery and surgery simulation with an articulator, condylar position control during surgery, working with surgeons to achieve a condylar portion stabilization system (with the CAD), quickly set up a mobilization of the mandible by physiotherapy. © EDP Sciences, SFODF, 2016.

Human papillomavirus-positive oropharyngeal squamous cell carcinoma is increasing in incidence worldwide. Current treatments are associated with high survival rates but often result in significant long-term toxicities. In particular, long-term dysphagia has a negative impact on patient quality of life and health. The aim of PATHOS is to determine whether reducing the intensity of adjuvant treatment after minimally invasive transoral surgery in this favourable prognosis disease will result in better long-term swallowing function whilst maintaining excellent disease-specific survival outcomes. The study is a multicentre phase II/III randomised controlled trial for patients with biopsy-proven Human papillomavirus-positive oropharyngeal squamous cell cancer staged T1-T3 N0-N2b with a primary tumour that is resectable via a transoral approach. Following transoral surgery and neck dissection, patients are allocated into three groups based on pathological risk factors for recurrence. Patients in the low-risk pathology group will receive no adjuvant treatment, as in standard practice. Patients in the intermediate-risk pathology group will be randomised to receive either standard dose post-operative radiotherapy (control) or reduced dose radiotherapy. Patients in the high-risk pathology group will be randomised to receive either post-operative chemoradiotherapy (control) or radiotherapy alone. The primary outcome of the phase II study is patient reported swallowing function measured using the MD Anderson Dysphagia Inventory score at 12 months post-treatment. If the phase II study is successful, PATHOS will proceed to a phase III non-inferiority trial with overall survival as the primary endpoint. PATHOS is a prospective, randomised trial for Human papillomavirus-positive oropharyngeal cancer, which represents a different disease entity compared with other head and neck cancers. The trial aims to demonstrate that long-term dysphagia can be lessened by reducing the intensity

Prevention of visual field defects after macular hole surgery.

BACKGROUND\\/AIM: The pathogenesis of visual field loss associated with macular hole surgery is uncertain but a number of explanations have been proposed, the most convincing of which is the effect of peeling of the posterior hyaloid, causing either direct damage to the nerve fibre layer or to its blood supply at the optic nerve head. The purpose of this preliminary prospective study was to determine the incidence of visual field defects following macular hole surgery in cases in which peeling of the posterior hyaloid was confined only to the area of the macula. METHODS: 102 consecutive eyes that had macular hole surgery had preoperative and postoperative visual field examination using a Humphrey\\'s perimeter. A comparison was made between two groups: I, those treated with vitrectomy with complete posterior cortical vitreous peeling; and II, those treated with a vitrectomy with peeling of the posterior hyaloid in the area of the macula but without attempting a complete posterior vitreous detachment. Specifically, no attempt was made to separate the posterior hyaloid from the optic nerve head. Eyes with stage II or III macular holes were operated. Autologous platelet concentrate and non-expansile gas tamponade was used. Patients were postured prone for 1 week. RESULTS: In group I, 22% of patients were found to have visual field defects. In group II, it was possible to separate the posterior hyaloid from the macula without stripping it from the optic nerve head and in these eyes no pattern of postoperative visual field loss emerged. There were no significant vision threatening complications in this group. The difference in the incidence of visual field loss between group I and group II was significant (p=0.02). The anatomical and visual success rates were comparable between both groups. CONCLUSION: The results from this preliminary study suggest that the complication of visual field loss after macular surgery may be reduced if peeling of the posterior hyaloid is

To assess local recurrence, disease-free survival, and overall survival in magnetic resonance imaging (MRI)-predicted good prognosis tumors treated by surgery alone. The MERCURY study reported that high-resolution MRI can accurately stage rectal cancer. The routine policy in most centers involved in the MERCURY study was primary surgery alone in MRI-predicted stage II or less and in MRI "good prognosis" stage III with selective avoidance of neoadjuvant therapy. Data were collected prospectively on all patients included in the MERCURY study who were staged as MRI-defined "good" prognosis tumors. "Good" prognosis included MRI-predicted safe circumferential resection margins, with MRI-predicted T2/T3a/T3b (less than 5 mm spread from muscularis propria), regardless of MRI N stage. None received preoperative or postoperative radiotherapy. Overall survival, disease-free survival, and local recurrence were calculated. Of 374 patients followed up in the MERCURY study, 122 (33%) were defined as "good prognosis" stage III or less on MRI. Overall and disease-free survival for all patients with MRI "good prognosis" stage I, II and III disease at 5 years was 68% and 85%, respectively. The local recurrence rate for this series of patients predicted to have a good prognosis tumor on MRI was 3%. The preoperative identification of good prognosis tumors using MRI will allow stratification of patients and better targeting of preoperative therapy. This study confirms the ability of MRI to select patients who are likely to have a good outcome with primary surgery alone.

This pictorial essay reviews the computed tomography (CT) findings of afferent loop syndrome (ALS) in various pathological conditions to demonstrate the contribution of a common imaging modality-that is, abdominal CT, used nowadays for various abdominal complaints-to the diagnosis of ALS. ALS is caused by obstruction of the duodenum and jejunum proximal to a gastrojejunostomy anastomosis. It is a rare complication after Billroth II subtotal gastrectomy and even more rare after total or subtotal gastrectomy with Roux-en-Y reconstruction. Although currently advanced medical treatment and endoscopic interventions have dramatically decreased the necessity of surgery for peptic ulcer disease, ALS may appear years after previously common operations. Alternatively, the use of surgical resection for early gastric cancer nowadays leads to an increasing rate of malignancy-related ALS. Clinically, ALS may be difficult to diagnose as its presentation may be vague and nonspecific, but it has a characteristic appearance on CT. Clinicians and radiologists should therefore be familiar with this rare complication. Prompt recognition and correct diagnosis of this syndrome and its probable etiology are important as a guide for treatment. This review illustrates the CT features of ALS in various conditions.

The European System for Cardiac Operation Risk Evaluation (EuroSCORE) II has not been tested yet for predicting long-term mortality. This study was undertaken to evaluate the relationship between EuroSCORE II and long-term mortality and to develop a new algorithm based on EuroSCORE II factors to predict long-term survival after cardiac surgery. Complete data on 10,033 patients who underwent major cardiac surgery during a 7-year period were retrieved from three prospective institutional databases and linked with the Italian Tax Register Information System. Mortality at follow-up was analyzed with time-to-event analysis. The Kaplan-Meier estimates of survival at 1 and 5 were, respectively, 95.0% ± 0.2% and 84.7% ± 0.4%. Both discrimination and calibration of EuroSCORE II decreased in the prediction of 1-year and 5-year mortality. Nonetheless, EuroSCORE II was confirmed to be an independent predictor of long-term mortality with a nonlinear trend. Several EuroSCORE II variables were independent risk factors for long-term mortality in a regression model, most of all very low ejection fraction (less than 20%), salvage operation, and dialysis. In the final model, isolated mitral valve surgery and isolated coronary artery bypass graft surgery were associated with improved long-term survival. The EuroSCORE II cannot be considered a direct estimator of long-term risk of death, as its performance fades for mortality at follow-up longer than 30 days. Nonetheless, it is nonlinearly associated with long-term mortality, and most of its variables are risk factors for long-term mortality. Hence, they can be used in a different algorithm to stratify the risk of long-term mortality after surgery. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc.

The purpose of this study was to determine the effect of orthognathic surgery on psychological status. The subjects were 119 patients (38 males and 81 females, mean age 25.5±9.4 years) who underwent orthognathic surgery. They were divided into class III (84 patients), class II (20 patients), and class I (15 patients) groups according to the anteroposterior skeletal pattern, and they were also divided into an asymmetry group (51 patients) and a symmetry group (68 patients). We assessed psychological status using the Minnesota Multiphasic Personality Inventory (MMPI) before surgery and at more than 6 months after surgery. The MMPI scores for the depression, hysteria, psychasthenia, and social introversion scales were significantly higher than standard values before surgery, and the hypomania scale significantly lower. The cannot say scale, depression scale, and hysteria scale decreased significantly after surgery. A comparison of MMPI scores among the groups showed the depression scale in the class III group to be higher than those in the class I and II groups; there was no significant difference between the asymmetry and symmetry groups. In conclusion, orthognathic surgery has a positive influence on the psychological status of patients with jaw deformities, especially patients with skeletal class III malocclusion.

In nonrandomized trials, neoadjuvant treatment was reported to prolong survival in patients with pancreatic cancer. As neoadjuvant chemoradiation is established for the treatment of rectal cancer we examined the value of neoadjuvant chemoradiotherapy in pancreatic cancer in a randomized phase II trial. Radiological staging defining resectability was basic information prior to randomization in contrast to adjuvant therapy trials resting on pathological staging. Patients with resectable adenocarcinoma of the pancreatic head were randomized to primary surgery (Arm A) or neoadjuvant chemoradiotherapy followed by surgery (Arm B), which was followed by adjuvant chemotherapy in both arms. A total of 254 patients were required to detect a 4.33-month improvement in median overall survival (mOS). The trial was stopped after 73 patients; 66 patients were eligible for analysis. Twenty nine of 33 allocated patients received chemoradiotherapy. Radiotherapy was completed in all patients. Chemotherapy was changed in 3 patients due to toxicity. Tumor resection was performed in 23 vs. 19 patients (A vs. B). The R0 resection rate was 48 % (A) and 52 % (B, P = 0.81) and (y)pN0 was 30 % (A) vs. 39 % (B, P = 0.44), respectively. Postoperative complications were comparable in both groups. mOS was 14.4 vs. 17.4 months (A vs. B; intention-to-treat analysis; P = 0.96). After tumor resection, mOS was 18.9 vs. 25.0 months (A vs. B; P = 0.79). This worldwide first randomized trial for neoadjuvant chemoradiotherapy in pancreatic cancer showed that neoadjuvant chemoradiation is safe with respect to toxicity, perioperative morbidity, and mortality. Nevertheless, the trial was terminated early due to slow recruiting and the results were not significant. ISRCTN78805636; NCT00335543. (orig.) [de

Full Text Available Abstract Background Laparoscopic gastrectomy has recently been gaining popularity as a treatment for cancer; however, little is known about the benefits of intracorporeal (IC gastrointestinal anastomosis with pure laparoscopic distal gastrectomy (LDG compared with extracorporeal (EC anastomosis with laparoscopy-assisted distal gastrectomy (LADG. Methods Between June 2000 and December 2011, we assessed 449 consecutive patients with early-stage gastric cancer who underwent LDG. The patients were classified into three groups according to the method of reconstruction LADG followed by EC hand-sewn anastomosis (LADG + EC (n = 73, using any of three anastomosis methods (Billroth-I (B-I, Billroth-II (B-II or Roux-en-Y (R-Y; LDG followed by IC B-I anastomosis (LDG + B-I (n = 248; or LDG followed by IC R-Y anastomosis (LDG + R-Y (n = 128. The analyzed parameters included patient and tumor characteristics, operation details, and post-operative outcomes. Results The tumor location was significantly more proximal in the LDG + R-Y group than in the LDG + B-I group (P P P  Conclusions Intracorporeal mechanical anastomosis by either the B-I or R-Y method following LDG has several advantages over at the LADG + EC, including small wound size, reduced invasiveness, and safe anastomosis. Although additional randomized control studies are warranted to confirm these findings, we consider that pure LDG is a useful technique for patients with early gastric cancer.

While surgery is proned in low-grade glioma (LGG), the invasion of functional areas frequently prevents a complete resection. We report the first case of a patient operated on for a left frontal LGG, diagnosed because of seizures, with partial resection due to an invasion of the controlateral hemisphere. Chemotherapy enabled a regression of this controlateral extension. Postchemotherapy surgery performed with intraoperative functional mapping then allowed a complete resection, without sequelae. The patient has a normal socio-professional life, with no seizure. No other treatment was given. There was no recurrence, with a follow-up of 2 years since the second surgery (3.5 years since the first symptom). We propose a new therapeutic strategy in unresectable LGG, with preoperative chemotherapy, to make a radical surgery possible in a second step, while preserving the quality of life.

A dramatic increase in the incidence of the diffuse form of gastric adenocarcinomas and particularly signet ring cell carcinomas has been observed in Western countries. Evidence is accruing that signet ring cell carcinomas may have inherent chemo resistance leaving many clinicians unsure of the benefits of delaying surgery to pursue a neoadjuvant approach. PRODIGE-19-FFCD1103-ADCI002 is a prospective multicentre controlled randomised phase II/III trial comparing current standard of care of perioperative chemotherapy (2x3 cycles of Epirubicin, cisplatin, 5-fluorouracil) with a strategy of primary surgery followed by adjuvant chemotherapy (6 cycles of Epirubicin, cisplatin, 5-fluorouracil) in patients with a stage IB-III gastric signet ring cell tumour. The principal objective of the phase II study (84 patients) is to determine if the experimental arm (primary surgery followed by adjuvant chemotherapy) has sufficient interest in terms of percentage of living patients at 24 months to be evaluated in a phase III trial. If 7 or less patients in the experimental arm are alive at 24 months, phase III will not be initiated. The primary objective of phase III (230 additional patients) is to demonstrate superiority of the experimental arm in terms of overall survival. Secondary endpoints include overall survival at 36 months, disease free survival at 24 and 36 months, R0 resection rates, treatment tolerance, postoperative mortality and morbidity evaluated by Clavien-Dindo severity index, the prognostic impact of positive peritoneal cytology and the assessment of quality of life. An ancillary study will assess the emotional and cognitive impact of surgery and perioperative chemotherapy for both the patient and their partner. As inherent chemo resistance of signet ring cell tumours and delay in definitive surgery may favour tumour progression we hypothesise that a policy of primary surgery followed by adjuvant chemotherapy will improve overall survival compared to a standard

Several outcomes of pregnancy after bariatric surgery are currently being studied. This cross-sectional, retrospective study evaluated the obstetric and perinatal outcomes of pregnancies in 19 women who underwent bariatric surgery, as well as the growth and development of their children, in the Southern Brazil. Among these women, 11 children were born prior to surgery and 32 were born post-surgery. The mean time between the surgery and the first pregnancy was 42.96 months. Preterm newborns were more common among the pre-surgery childbirths. Regarding growth, normal weights were observed in 27.3 % of the children in the pre-surgery births and obesity was observed in 54.5 %. In contrast, normal weights were observed in 59.4 % of the children born during the postoperative period and obesity was observed in 31.2 %. The average excess weight that the women lost prior to pregnancy was 64.88. Speech delays were found in three male children evaluated using the Denver Developmental Screening Test II. A statistical association was found between the interval from the surgery to the pregnancy and the outcome of the questionable Denver II test results (p = 0.011). Except for the large index of low birth weight, it can be concluded that pregnancy after bariatric surgery is safe. The growth rate was found to be adequate in the children born after the surgery, with reduced obesity. Although changes in speech development were detected, no factors were supported an association with pregnancy after bariatric surgery.

To analyze critically the effectiveness and value of bibliometric indicators in journals of Surgery or Cardiovacular Surgery in the context of the postgraduate programs of CAPES Medicine III. A sampling with 16 academic programs and one professional master of Medicine III, encompassing the General and Digestive System Surgery, Cardiovascular Surgery and Multidisciplinary courses with such contents, was evaluated. Thomson Reuters/ISI (JCR), Elsevier/Scopus (SJR), and also Scielo databases were used. Only in seven programs, the teachers had an average of Qualis A1 articles greater than the others strata. Eleven journals in the surgical area are in stratum A1 (5%) and it reaches 25% in Cardiovascular Surgery. Among the six journals with the largest number of publications Qualis A1 in area Medicine III, five are from non-specific areas. The Acta Cirúrgica Brasileira represented 58% of the publications in the stratum A2. There are some obstacles in the Qualis classification with little uniformity among the Medicine areas I, II and III. A permanent committee should be set to update the Qualis, composed by the three medical areas. It should be considered using other index databases and the unification of the Qualis criteria for journals in medicine. Rating criteria of multi and transdisciplinary journals need to be reviewed. It is essential an institutional financial support for national journals chosen by peers aiming to provide a full computerization process and a professional reviewer of the English language, in order to increase the impact factor.

To analyze recurrence patterns in patients with cancer of the esophagus or gastroesophageal junction treated with either preoperative chemoradiotherapy (CRT) plus surgery or surgery alone. Recurrence pattern was analyzed in patients from the previously published CROSS I and II trials in relation to radiation target volumes. CRT consisted of five weekly courses of paclitaxel and carboplatin combined with a concurrent radiation dose of 41.4 Gy in 1.8-Gy fractions to the tumor and pathologic lymph nodes with margin. Of the 422 patients included from 2001 to 2008, 418 were available for analysis. Histology was mostly adenocarcinoma (75%). Of the 374 patients who underwent resection, 86% were allocated to surgery and 92% to CRT plus surgery. On January 1, 2011, after a minimum follow-up of 24 months (median, 45 months), the overall recurrence rate in the surgery arm was 58% versus 35% in the CRT plus surgery arm. Preoperative CRT reduced locoregional recurrence (LRR) from 34% to 14% (P < .001) and peritoneal carcinomatosis from 14% to 4% (P < .001). There was a small but significant effect on hematogenous dissemination in favor of the CRT group (35% v 29%; P = .025). LRR occurred in 5% within the target volume, in 2% in the margins, and in 6% outside the radiation target volume. In 1%, the exact site in relation to the target volume was unclear. Only 1% had an isolated infield recurrence after CRT plus surgery. Preoperative CRT in patients with esophageal cancer reduced LRR and peritoneal carcinomatosis. Recurrence within the radiation target volume occurred in only 5%, mostly combined with outfield failures.

It is well known that the organizational model of day surgery, concerning surgical problems defined by the literature as minor, has the aim of optimising the use of hospital resources and facilitating patients and their families, from a psychological and social point of view, by reducing hospitalisation time and the associated complications, and ensuring the same efficacy and more appropriateness of treatment. This study is firstly aimed at analysing the impact that the healthcare policy of the Emilia Romagna Region has had on the development of day surgery practice. Secondly, it compares the patients treated in orthopaedic day surgery in the hospitals of Bologna, Modena, Ferrara, Parma, Reggio Emilia, Maggiore hospital of Bologna and Rizzoli Orthopaedic Institute of Bologna (II.OO.R). In the period 1997-2000 there was a marked increase in the number of operations carried out in day surgery in all of the above-mentioned hospitals. Also in the unispecialistic orthopaedic hospital there was a surprising increase in the percentage of operations carried out in day surgery with respect to the total number of operations performed. The aim of the Rizzoli Orthopaedic Institute and the Emilia Romagna Region is to further implement this form of healthcare, contextually potentiating the appropriateness of hospital admission and avoiding, when not necessary, other forms of healthcare.

Malignant gliomas of the brain managed by radiotherapy after surgery

Energy Technology Data Exchange (ETDEWEB)

Fichardt, T.; Sandison, A.G. (Pretoria Univ. (South Africa). Dept. of Radiotherapy)

The article reviews the literature and gives an account of the authors' experience during a 20-year period (1960-1980) of the value of radiotherapy after surgery in the management of 76 patients suffering from brain gliomas classified into 3 grades according to the degree of anaplasia present in the histological sections, viz. grades II, III and IV. Radiotherapy was not given to grade I malignant gliomas as they are treated by surgery only. The period is divided into 2 subperiods. The first is from 1960-1972 when part-brain, high-dose irradiation following surgery was used on 33 patients in various age groups. The second period covers whole-brain, low-dose irradiation following surgery and was used on 43 patients in various age groups.

Infective endocarditis (IE) is a serious disease whose prognosis depends on early management. Aortic location is characterized by its evolution toward myocardial failure and the high number of complications reasons for early surgery. To compare the short- and mid-terms results of surgery for aortic infective endocarditis (IE) in the active phase and the healed phase. We analyzed retrospectively the data of 48 consecutive patients operated for aortic infective endocarditis between January 2000 and January 2012. The data on operative mortality, morbidity and major cardiovascular events (mortality, recurrent endocarditis, reintervention, and stroke) were analyzed. Twenty-three patients (48%) underwent surgery during the active phase (group I), 19 on native and 4 on prosthetic valves, and 25 patients (52%) were operated during healed endocarditis (group II) only on native valve. Mean age was 39 years (12-81) with a male predominance (83%). Rheumatic valvular disease was the main etiology of underlying valvular disease in both groups (85%). The clinical feature was dominated by signs of cardiogenic shock in group I and dyspnea exertion stage III-IV NYHA in group II. Streptococcus and Staphylococcus germs were most frequently encountered. Indication for surgery was heart failure in group I, it was related to the symptoms, the severity of valvular disease and its impact on the left ventricle in group II. An aortic valve replacement with a mechanical prosthesis was performed in the majority of cases (83%). Postoperative mortality concerned only one patient in group I. Twenty-one patients (44%) were followed for a mean of 30 months (1-72). One patient in group II died following cerebral hemorrhagic stroke related to accident with vitamin K antagonist. In both groups, there was an improvement in the functional class. No recurrence of endocarditis was noted in both groups during follow-up. The prognosis of infective endocarditis of the aortic valve is severe due to the fast

Although more than 1500 publications on hallux valgus can be found in the current literature, none of them have reported on the course of pain resolution after hallux valgus surgery. Thus, this study aimed to investigate pain resolution after hallux valgus surgery and to identify predictive factors associated with residual pain at 6 months after surgery. We prospectively followed up 308 patients who underwent hallux valgus surgery at a tertiary hospital at 6 months and 2 years after surgery. Multivariate logistic regression analysis was performed to evaluate the risk factors associated with residual pain after surgery. Ninety-four patients (31%) had some degree of residual pain at 6 months after surgery. After excluding 4 patients who developed osteoarthritis of the first metatarsophalangeal joint over the next 18 months, 73 of the remaining 90 (81%) experienced improvement in visual analog scale (VAS) by the 2-years follow-up. Their median VAS improved from 4 (interquartile range [IQR] 3, 5) at 6 months to 0 (IQR 0, 3) at 2 years (P < .001). A higher preoperative VAS increased the risk of having persistent pain at 6 months after sugery (odds ratio [OR] 1.388, 95% confidence interval [CI] 1.092, 1.764, P = .007), whereas a higher preoperative Mental Component Score of SF-36 (MCS) reduced this risk (OR 0.952, 95% CI 0.919, 0.987, P = .007). As much as 31% of patients will have residual pain at 6 months after surgery. Preoperative VAS and MCS are predictors for residual pain. However, these patients will continue to improve over the next 18 months, with 71% of them being pain free at 2 years after surgery. Level II, prospective comparative study. © The Author(s) 2016.

METHODS: In this prospective cohort study, we recruited patients in a 2-month period and included consecutive patients scheduled for bilateral small-incision phacoemulsification cataract surgery....... The exclusion criteria were (i) corneal and/or retinal pathology that could lead to automated refraction miscalculation and (ii) surgery complications. Automated refraction was measured 1 week and 1 month after surgery. RESULTS: Ninety-five patients met the in- and exclusion criteria and completed follow......-up. The mean refractive shift in spherical equivalent was -0.02 dioptre (D) between 1 week and 1 month after surgery and not statistical significant (p = 0.78, paired t-test). The magnitude of refractive shift in either myopic or hyperopic direction was neither correlated to age, preoperative corneal...

The aim of this study was to compare evaluations of the aesthetic outcome of class II orthognathic patients, as performed by observers with varying expertise using three-dimensional (3D) facial images, and to examine the relationship of aesthetic ratings in relation to quantitative surgical changes. Pre- and postoperative 3D facial images of 20 surgically treated class II patients (13 female, 7 male) were assessed for aesthetics by orthodontists, maxillofacial surgeons, and laypeople. Attractiveness ratings for the lips, chin, and overall facial aesthetics were evaluated on a 5-point Likert scale. Correlation between the aesthetic scores was obtained and quantitative surgical changes were examined. For all groups of observers, significant improvements in attractiveness scores were found, especially for the chin assessment. Orthodontists perceived the greatest improvement and laypeople the smallest. Overall, laypeople scored higher with less variability, but with lower intra- and inter-observer agreement. No significant correlation was found between the aesthetic improvement and soft tissue surgical changes. To avoid patient dissatisfaction, it is important to bear in mind that the demands and perception of aesthetic improvement after orthognathic surgery are higher for clinicians than for the general public.

To investigate the efficacy of suspension laryngoscopic surgery for benign laryngotracheal stenosis (LTS). Thirty-two patients (aged from 5 to 70 years with a median of 36 years) with benign LTS were studied retrospectively who were treated by suspension laryngoscopic surgery with or without assistance of CO₂ Laser for LTS. Stents were placed in 17 cases. Among 32 patients, 13 cases were with LST in Cotton I, 8 cases in Cotton II, and 11 cases in Cotton III; 23 were with single level narrow, and 9 cases with multi-level narrow; the average narrow length was 1.3 cm and the average diameter at maximum stenosis was 0.5 cm; and 19 cases underwent tracheostomy before surgery. Follow-up period ranged from 1 to 18 years with median time of 10 years. Twenty-six patients (81.2%) were successfully decannulated with good airway patency and effective phonation. Six cases failed and 1 case of them was changed to open surgery. Among 17 cases with stent placement, 4 cases were applied additionally with T tube (effective rate of 50.0%), 1 case with laryngeal keel, 12 cases with stents alone (effective rate of 66.7%). Stent-related complications occurred in 2 cases. Patients with cotton I-II had a successful rate of 100% (21/21), while patients with Cotton III showed poor effectiveness (5/11), with a statistical significant difference between two groups (χ² = 14.098, P = 0.001). The patients with single level LTS were successfully treated by suspension laryngoscopic surgery with 100% successful rate (23/23), while the patients with multi-level LTS showed poor effectiveness (3/9), with a statistical significant difference between two groups (χ² = 18.872, P = 0.000) . Suspension laryngoscopic microsurgery can treat single level LTS with good results and also can be used as a pre-surgery in treatment of multi-level LTS with the virtue of minimal trauma and short recovery time. Application of stents can be helpful for suspension laryngoscope surgery for LST.

To report the results of minimally invasive surgery in patients with stage I or II thymoma in the Masaoka classification. The reference technique is partial or complete thymectomy by sternotonomy. A retrospective single-center study of a prospective database including all cases of thymoma operated from April 2009 to February 2015 by minimally invasive techniques: either videosurgery (VATS) or robot-assisted surgery (RATS). The surgical technique, type of resection, length of hospital stay, postoperative complications and recurrences were analysed. Our series consisted of 22 patients (15 women and 7 men). The average age was 53 years. Myasthenia gravis was present in 12 patients. Eight patients were operated on by VATS and 14 patiens by RATS. There were no conversions to sternotomy and no perioperative deaths. The mean operating time was 92min for VATS and 137min for RATS (P<0.001). The average hospital stay was 5 days. The mean weight of the specimen for the VATS group was 13.2 and 45.7mg for the RATS group. Twelve patients were classified Masaoka stage I and 10 were stage II. According to the WHO classification there were 7 patients type A, 5 type AB, 4 type B1, 4 type B2 4 and 2 type B3. As proposed by the Group ITMIG-IASLC in 2015 all patients corresponded to group I. The mean follow-up period was 36 months. We noted 3 major perioperative complications according to the Clavien-Dindo classification: one pneumonia, one phrenic nerve paralysis and one recurrent laryngeal nerve palsy. We observed one case of local recurrence at 22 months. Following surgery 4 patients were treated with radiotherapy and 2 patients with chemotherapy. The minimally invasive route is safe, relatively atraumatic and may be incorporated in the therapeutic arsenal for the treatment of Masaoka stage I and II thymoma as an alternative to conventional sternotomy. RATS and VATS are two minimally invasive techniques and the results in the short and medium term are

Indications and contraindications for surgery in esophageal cancer

International Nuclear Information System (INIS)

Carriquiry, G.

2004-01-01

In this story we will present the main problems that we have as a surgeons at the moment to decide the indication for surgery in patients with esophageal cancer. Undoubtedly, the patient that will be submitted to surgery must have strict criteria in order to obtain good results. The patient must be compensated from respiratory, cardiovascular, hepatic and renal point of view with a (IMC) above 20, with Karnofsky index above 80% (wanders well), that declares the acceptance of surgery as well as the conserved appetite. After deciding the surgery according to the general conditions, should be discuss the type of procedure, based primarily on tumor topography, because there are different results both morbidity and long-term survival. The indications for resection or palliative surgery depend on the tumor stage. The indications for resection surgery with conventional or eventual extended lymphadenectomy require a patient in good condition, good experience the surgical team and a good hospital support. In tumor stage I the indication is a supposedly curative surgery. The tumor stages II b, III and IV are the heritage of palliative surgery, with or without tumor resection. The age is not an absolute contraindication for surgery, but the hypertension, liver cirrhosis, respiratory diseases with severe functional impact, ischemic heart disease, dilated heart with lowered LVEF, severe psychological disorders and the loss of appetite are contraindication. The morbidity and mortality has declined markedly due to technological advances and specialization of surgical groups, so that surgery is still the best treatment for selected patients

Since improvement of facial aesthetics after orthognathic surgery moves increasingly into the focus of patients, prediction of soft tissue response to hard tissue movement becomes essential for planning. The aim of this study was to assess the facial soft tissue response in skeletal class II and III patients undergoing orthognathic surgery and to compare the potentials of cephalometry and two-dimensional (2-D) photogrammetry for predicting soft tissue changes. Twenty-eight patients with class II relationship and 33 with class III underwent bimaxillary surgery. All subjects had available both a traced lateral cephalogram and a traced lateral photogram taken pre- and postsurgery in natural head position (median follow-up, 9.4 ± 0.6 months). Facial convexity and lower lip length were highly correlated with hard tissue movements cephalometrically in class III patients and 2-D photogrammetrically in both classes. In comparison, cephalometric correlations for class II patients were weak. Correlations of hard and soft tissue movements between pre- and postoperative corresponding landmarks in horizontal and vertical planes were significant for cephalometry and 2-D photogrammetry. No significant difference was found between cephalometry and 2-D photogrammetry with respect to soft to hard tissue movement ratios. This study revealed that cephalometry is still a feasible standard for evaluating and predicting outcomes in routine orthognathic surgery cases. Accuracy could be enhanced with 2-D photogrammetry, especially in class II patients.

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

Key textbooks in the development of modern american plastic surgery: the first half of the twentieth century.

Science.gov (United States)

Haddock, Nicholas T; McCarthy, Joseph G

2013-07-01

A number of historical texts published during the first half of the twentieth century played a pivotal role in shaping and defining modern plastic surgery in the United States. Blair's Surgery and Diseases of the Mouth and Jaws (1912), John Staige Davis's Plastic Surgery: Its Principles and Practice (1919), Gillies's Plastic Surgery of the Face (1920), Fomon's Surgery of Injury and Plastic Repair (1939), Ivy's Manual of Standard Practice of Plastic and Maxillofacial Surgery, Military Surgery Manuals (1943), Padgett and Stephenson's Plastic and Reconstructive Surgery (1948), and Kazanjian and Converse's The Surgical Treatment of Facial Injuries (1949) were reviewed. These texts were published at a time when plastic surgery was developing as a distinct specialty. Each work represents a different point in this evolution. All were not inclusive of all of plastic surgery, but all had a lasting impact. Four texts were based on clinical experience from World War I; one included experience from World War II; and two included experience from both. One text became a military surgical handbook in World Wars I and II, playing an important role in care for the wounded. History has demonstrated that times of war spark medical/surgical advancements, and these wars had a dramatic impact on the development of reconstructive plastic surgery. Each of these texts documented surgical advancements and provided an intellectual platform that helped shape and create the independent discipline of plastic surgery during peacetime. For many future leaders of plastic surgery, these books served as their introduction to this new field.

Mortality after surgery is frequent and severity of disease scoring systems are used for prediction. Our aim was to evaluate predictors for mortality after non-cardiac surgery. Adult patients admitted at our surgical intensive care unit between January 2006 and July 2013 was included. Univariate analysis was carried using Mann-Whitney, Chi-square or Fisher's exact test. Logistic regression was performed to assess independent factors with calculation of odds ratio and 95% confidence interval (95% CI). 4398 patients were included. Mortality was 1.4% in surgical intensive care unit and 7.4% during hospital stay. Independent predictors of mortality in surgical intensive care unit were APACHE II (OR=1.24); emergent surgery (OR=4.10), serum sodium (OR=1.06) and FiO 2 at admission (OR=14.31). Serum bicarbonate at admission (OR=0.89) was considered a protective factor. Independent predictors of hospital mortality were age (OR=1.02), APACHE II (OR=1.09), emergency surgery (OR=1.82), high-risk surgery (OR=1.61), FiO 2 at admission (OR=1.02), postoperative acute renal failure (OR=1.96), heart rate (OR=1.01) and serum sodium (OR=1.04). Dying patients had higher scores in severity of disease scoring systems and longer surgical intensive care unit stay. Some factors influenced both surgical intensive care unit and hospital mortality.

The euroSCORE II is a widely used pre-coronary artery bypass graft surgery (CAGS) risk score, but its predictive power lacks the specificity to predict outcomes in high-risk patients (surgery case mix, revascularisation techniques and related outcomes in recent years. We investigated the utility of Cardiac Magnetic Resonance Imaging (CMRI) in predicting immediate and six-week outcomes after CAGS. Fifty-two consecutive patients with high euroSCORE II (>16) and left ventricular (LV) dysfunction (magnetic resonance imaging parameters were assessed in patients who either had complications immediately post-surgery (n=35), six weeks post-surgery (n=20) or were uncomplicated. The average age of patients recruited was 69±5 years with high euroSCORE II (22±4) and low 2D-echocardiography LV ejection fraction (38%±2%). Cardiac magnetic resonance imaging results demonstrated that those with immediate complications had higher LV scar/infarct burden as a proportion of LV mass (17±3% vs 10±3%; p=0.04) with lower circumferential relaxation index (2.5±0.46 vs 2.8±0.56; p=0.05) compared to those with no complications. Early mortality from surgery was 17% (n=9) and was associated with lower RV stroke volume (55±12 vs 68±18; p=0.03) and higher LV infarct scar/burden (18±2% vs 10±2%, p=0.04). Cardiac magnetic resonance imaging showed patients with complications at six weeks post-surgery had higher LV scar/infarct burden (14.5±2% vs 6.8±2%, p=0.03) compared to those without complications. Cardiac magnetic resonance imaging preoperative LV and RV parameters are valuable in assessing the likelihood of successful outcomes from CAGS in high-risk patients with LV dysfunction.

Purpose: To determine whether patients with Masaoka stage II thymoma benefit from adjuvant radiation therapy after complete tumor resection. Methods and Materials: A total of 107 patients with stage II thymoma who underwent complete resection of their tumors between September 1964 and October 2006 were retrospectively analyzed. Sixty-six patients were treated with adjuvant radiotherapy, and 41 patients received surgery alone. Results: Eight patients (7.5%) had a relapse of their disease, including two patients (4.5%) who had surgery alone, and 6 patients (9.5%) who had adjuvant radiation therapy. Disease-free survival rates at 5 and 10 years were 92.3% and 82.6%, respectively, for the surgery-plus-radiation group, and 97.6% and 93.1%, respectively, for the group that underwent surgery alone (p = 0.265). Disease-specific survival rates at 5 and 10 years were 96.4% and 89.3%, respectively, for the surgery-plus-radiation group and 97.5% and 97.5% for the surgery group (p = 0.973). On univariate analysis, patients with type B3 thymomas had the lowest disease-free survival rates among all subtypes (p = 0.001), and patients with large thymomas (>7 cm) had lower disease-specific survival rates than those with small tumors (<7 cm) (p = 0.017). On multivariate analysis, histological type (type B3) thymoma was a significant independent prognostic factor. Conclusions: Adjuvant radiotherapy after complete tumor resection for patients with stage II thymoma did not significantly reduce recurrence rates or improve survival rates. Histological type (type B3) thymoma was a significant independent prognostic factor. Further investigation should be carried out using a multicenter randomized or controlled study.

The aim was to evaluate the effect of diquafosol on tear film parameters and corneal aberrations after cataract surgery. This retrospective, comparative, observational case series included patients who underwent cataract surgery with or without peri-operative use of diquafosol three per cent ophthalmic solution. Patients in group I (31 eyes) were treated with diquafosol three per cent ophthalmic solution six times a day from one week before surgery to three months after surgery. Patients in group II (33 eyes) underwent cataract surgery without being administered diquafosol. Tear film break-up time (BUT), the ocular surface disease index (OSDI), the Oxford Scheme score, Schirmer's test I and corneal aberrations were determined before and at one and three months post-surgery. In group I, the BUT, OSDI and Oxford Scheme score showed significant improvement at one and three months post-surgery (p = 0.002 for BUT at one month and three months, p = 0.023 and p = 0.049 for OSDI at one month and three months and p = 0.001 and p = 0.026 for Oxford Scheme at one month and three months), compared to baseline. In group II, the BUT, OSDI and Oxford Scheme score did not show any significant improvement during the follow-up period. In both groups, Schirmer's test I significantly decreased at three months post-surgery (p = 0.011 for group I and p = 0.034 for group II), compared to baseline. There were significant differences in the BUT and OSDI between the groups at three months post-surgery (p = 0.037 for BUT and p = 0.011 for OSDI). Regarding the corneal aberration, there were no significant differences between the groups at three months post-surgery. Peri-operative application of diquafosol three per cent ophthalmic solution may prevent dry eye-related ocular surface changes accompanied by improvement of ocular symptom. No definite changes in corneal aberrations were noted. © 2017 Optometry Australia.

Purpose: We retrospectively compared the survival rate in patients with non-small-cell lung cancer (NSCLC) treated with radiofrequency ablation (RFA), surgery, or chemotherapy according to lung cancer staging. Materials and Methods: From 2000 to 2004, 77 NSCLC patients, all of whom had WHO performance status 0–2 and were >60 years old, were enrolled in a cancer registry and retrospectively evaluated. RFA was performed on patients who had medical contraindications to surgery/unsuitability for surgery, such as advanced lung cancer or refusal of surgery. In the RFA group, 40 patients with inoperable NSCLC underwent RFA under computed tomography (CT) guidance. These included 16 patients with stage I to II cancer and 24 patients with stage III to IV cancer who underwent RFA in an adjuvant setting. In the comparison group (n = 37), 13 patients with stage I to II cancer underwent surgery; 18 patients with stage III to IV cancer underwent chemotherapy; and 6 patients with stage III to IV cancer were not actively treated. The survival curves for RFA, surgery, and chemotherapy in these patients were calculated using Kaplan–Meier method. Results: Median survival times for patients treated with (1) surgery alone and (2) RFA alone for stage I to II lung cancer were 33.8 and 28.2 months, respectively (P = 0.426). Median survival times for patients treated with (1) chemotherapy alone and (2) RFA with chemotherapy for stage III to IV cancer were 29 and 42 months, respectively (P = 0.03). Conclusion: RFA can be used as an alternative treatment to surgery for older NSCLC patients with stage I to II inoperable cancer and can play a role as adjuvant therapy with chemotherapy for patients with stage III to IV lung cancer.

As, quest for beauty has always been an aim. There is a need to define the "ideal" beautifull breast with objective caracteristics, usable in plastic, reconstructive and aesthetic surgery. After, we have defined the necessary parameters usable in breast surgery. We realized an anthropomorphic study including 70 volunteer women and one molded model. Multiple pictures have been taken for each volunteer, that were evaluated and noted by five plastic surgeon, five doctors from other speciality, five women, five men. A twenty notation was used for this study. The main values for the ten women that obtained best notation (>or=14/20) were used in order to defined the ideal measures for surgery. Breast arrow and breast arrow over the trunck height were the most significant factors. According statistical studies, this fraction is about 0,387 (P=0,000969). The nice breast has a round shape and look like juvenile breast. Bra size, cup size, base, segments II and III, fraction II/III are not significant in our series of (non operated) natural breast. The ideal breast is in harmony and proportional to the trunck height, with the main fraction of breast arrow on the trunck height about 0,387 in our serie.

The aims of this study were to determine whether ectopic pacemakers are present after meals in the Roux limbs of dogs after vagotomy and Roux gastrectomy, whether these pacemakers slow gastric emptying of liquids or solids, and whether abolishing the pacemakers with electric pacing might speed any slow emptying that occurs. In six dogs that underwent vagotomy and Roux gastrectomy and in four dogs that underwent vagotomy and Billroth gastrectomy (controls), myoelectric activity of the Roux limb or duodenum was measured during gastric emptying of a 500 kcal mixed meal of 99mTc-labeled cooked egg and 111In-labeled milk. Roux dogs were tested with and without pacing of the Roux limb. Roux dogs showed ectopic pacemaker in the Roux limb that drove the pacesetter potentials of the limb in a reverse, or orad, direction during 57% of the postprandial recordings. Billroth dogs had no ectopic pacemakers (p less than 0.05). Liquids emptied more slowly in Roux dogs (half-life (t1/2) = 121 +/- 15 minutes) than in Billroth dogs (t1/2 = 43 +/- 9 minutes; p less than 0.05), but solids emptied similarly in both groups of dogs (t1/2 approximately 8 hours). Pacing the Roux limb abolished the ectopic pacemakers, restored the slow emptying of liquids to the more rapid rate found in the Billroth dogs (t1/2: paced Roux, 72 +/- 15 minutes; Billroth, 43 +/- 9 minutes; p greater than 0.05) and did not change emptying of solids. The conclusion was that ectopic pacemakers present in the Roux limb after vagotomy and Roux gastrectomy drove the limb in a reverse direction and slowed emptying of liquids after the operation. The defect was corrected by pacing the Roux limb in a forward direction

A patient-based outcome measure with good measurement properties is urgently needed for use in clinical trials of foot surgery. We evaluated an existing foot pain and disability questionnaire (the Manchester Foot Pain and Disability Questionnaire) for its suitability as an outcome measure in the context of hallux valgus corrective surgery. Interviews with patients led to initial changes, resulting in 20 candidate questionnaire items with five response categories each. These were tested in a prospective study of 100 patients (representing 138 foot operations) undergoing hallux valgus corrective surgery. Analysis of underlying factor structure, dimensionality, internal reliability, construct validity and responsiveness of the questionnaire items in relation to (i) SF-36 general health survey and (ii) American Orthopaedic Foot & Ankle Society (AOFAS) hallux clinical scale resulted in a final 16 item questionnaire (the 'Manchester-Oxford Foot Questionnaire' (MOXFQ)), consisting of three domains/scales: 'Walking/standing' (seven items), 'Pain' (five items) and 'Social interaction' (four items) each having good measurement properties. All three domains were unidimensional. The new 16-item MOXFQ has good measurement properties in the context of outcomes assessment of surgery for hallux valgus. Future studies should assess the MOXFQ in the context of surgery for other foot and ankle conditions.

Full Text Available OBJECTIVE: To evaluate early and mid-term results in patients undergoing proximal thoracic aortic redo surgery. METHODS: We analyzed 60 patients (median age 60 years, median logistic EuroSCORE 40 who underwent proximal thoracic aortic redo surgery between January 2005 and April 2012. Outcome and risk factors were analyzed. RESULTS: In hospital mortality was 13%, perioperative neurologic injury was 7%. Fifty percent of patients underwent redo surgery in an urgent or emergency setting. In 65%, partial or total arch replacement with or without conventional or frozen elephant trunk extension was performed. The preoperative logistic EuroSCORE I confirmed to be a reliable predictor of adverse outcome- (ROC 0.786, 95%CI 0.64-0.93 as did the new EuroSCORE II model: ROC 0.882 95%CI 0.78-0.98. Extensive individual logistic EuroSCORE I levels more than 67 showed an OR of 7.01, 95%CI 1.43-34.27. A EuroSCORE II larger than 28 showed an OR of 4.44 (95%CI 1.4-14.06. Multivariate logistic regression analysis identified a critical preoperative state (OR 7.96, 95%CI 1.51-38.79 but not advanced age (OR 2.46, 95%CI 0.48-12.66 as the strongest independent predictor of in-hospital mortality. Median follow-up was 23 months (1-52 months. One year and five year actuarial survival rates were 83% and 69% respectively. Freedom from reoperation during follow-up was 100%. CONCLUSIONS: Despite a substantial early attrition rate in patients presenting with a critical preoperative state, proximal thoracic aortic redo surgery provides excellent early and mid-term results. Higher EuroSCORE I and II levels and a critical preoperative state but not advanced age are independent predictors of in-hospital mortality. As a consequence, age alone should no longer be regarded as a contraindication for surgical treatment in this particular group of patients.

Ultrasound description of Pecs II (modified Pecs I): a novel approach to breast surgery.

Science.gov (United States)

Blanco, R; Fajardo, M; Parras Maldonado, T

2012-11-01

The Pecs block (pectoral nerves block) is an easy and reliable superficial block inspired by the infraclavicular block approach and the transversus abdominis plane blocks. Once the pectoralis muscles are located under the clavicle the space between the two muscles is dissected to reach the lateral pectoral and the medial pectoral nerves. The main indications are breast expanders and subpectoral prosthesis where the distension of these muscles is extremely painful. A second version of the Pecs block is described, called "modified Pecs block" or Pecs block type II. This novel approach aims to block at least the pectoral nerves, the intercostobrachial, intercostals III-IV-V-VI and the long thoracic nerve. These nerves need to be blocked to provide complete analgesia during breast surgery, and it is an alternative or a rescue block if paravertebral blocks and thoracic epidurals failed. This block has been used in our unit in the past year for the Pecs I indications described, and in addition for, tumorectomies, wide excisions, and axillary clearances. The ultrasound sequence to perform this block is shown, together with simple X-ray dye images and gadolinium MRI images to understand the spread and pathways that can explain the benefit of this novel approach.

Full Text Available ABSTRACT OBJECTIVE: To evaluate the progression of the contralateral hip after unilateral reconstruction of hip dislocation in patients classified as GMFCS IV-V; and to identify potential prognostic factors for their evolution. METHODS: This was a retrospective study on 17 patients with spastic cerebral palsy, who were classified on the GMFCS scale (Gross Motor Functional Classification System as degrees IV and V, and who underwent unilateral reconstruction surgery to treat hip dislocation (adductor release, femoral varus osteotomy and acetabuloplasty. The minimum postoperative follow-up was 30 months. The clinical parameters evaluated were sex, age at time of surgery, length of follow-up after surgery and range of abduction. The treatment parameters were use/nonuse of femoral shortening, application of botulinum toxin and any previous muscle releases. The radiographic parameters were Reimer's extrusion index (REI, acetabular angle (AA and the continuity of Shenton's line. RESULTS: Among the 17 patients evaluated, eight presented dislocation (group I and nine did not (group II. Group I comprised three males and five females; group II comprised one male and eight females. The mean age at the time of surgery among the group I patients was 62 months and the mean follow-up was 62 months. In group II, these were 98 and 83 months, respectively. There was a trend in which patients of greater age did not evolve with contralateral dislocation. Among the nine patients with the combination of REI < 30% and AA < 25°, only one presented dislocation during the follow-up. Contralateral subluxation occurred within the first two years after the surgery. CONCLUSION: Hips presenting REI < 30° and AA < 25° do not tend to evolve to subluxation and can be kept under observation. Preoperative clinical and radiographic measurements alone are not useful for indicating the natural evolution of non- operated hips. The critical period for subluxation is the first two

Myocardial injury after surgery is a risk factor for weaning failure from mechanical ventilation in critical patients undergoing major abdominal surgery.

Full Text Available Myocardial injury after noncardiac surgery (MINS is a newly proposed concept that is common among adults undergoing noncardiac surgery and associated with substantial mortality. We analyzed whether MINS was a risk factor for weaning failure in critical patients who underwent major abdominal surgery.This retrospective study was conducted in the Department of Critical Care Medicine of Peking University People's Hospital. The subjects were all critically ill patients who underwent major abdominal surgery between January 2011 and December 2013. Clinical and laboratory parameters during the perioperative period were investigated. Backward stepwise regression analysis was performed to evaluate MINS relative to the rate of weaning failure. Age, hypertension, chronic renal disease, left ventricular ejection fraction before surgery, Acute Physiologic and Chronic Health Evaluation II score, pleural effusion, pneumonia, acute kidney injury, duration of mechanical ventilation before weaning and the level of albumin after surgery were treated as independent variables.This study included 381 patients, of whom 274 were successfully weaned. MINS was observed in 42.0% of the patients. The MINS incidence was significantly higher in patients who failed to be weaned compared to patients who were successfully weaned (56.1% versus 36.5%; P<0.001. Independent predictive factors of weaning failure were MINS, age, lower left ventricular ejection fraction before surgery and lower serum albumin level after surgery. The MINS odds ratio was 4.098 (95% confidence interval, 1.07 to 15.6; P = 0.04. The patients who were successfully weaned had shorter hospital stay lengths and a higher survival rate than those who failed to be weaned.MINS is a risk factor for weaning failure from mechanical ventilation in critical patients who have undergone major abdominal surgery, independent of age, lower left ventricular ejection fraction before surgery and lower serum albumin levels after

The purpose of this study was to compare changes in temporomandibular joint (TMJ) and ramus morphology between class II and III cases before and after sagittal split ramus osteotomy (SSRO) and Le Fort I osteotomy. The subjects were 39 patients (78 sides) who underwent bi-maxillary surgery. They consisted of 2 groups (18 class II cases and 21 class III cases), and were selected randomly from among patients who underwent surgery between 2012 and 2016. The TMJ disc tissue and joint effusion were assessed by magnetic resonance imaging (MRI) and the TMJ space, condylar height, ramus height, ramus inclination and condylar square were assessed by computed tomography (CT), pre- and post-operatively. The number of joints with anterior disc displacement in class II was significantly higher than that in class III (p bi-maxillary surgery. The findings of the numerical analysis also demonstrated that reduction of condylar volume occurred frequently in class II, although TMJ disc position classification did not change significantly, as previously reported.

To evaluate the impact of enhanced recovery after surgery (ERAS) programs on postoperative complications of pancreatic surgery. Computer searches were performed in databases (including PubMed, Cochrane Library and Embase) for randomized controlled trials or case-control studies describing ERAS programs in patients undergoing pancreatic surgery published between January 1995 and August 2017. Two researchers independently evaluated the quality of the studies' extracted data that met the inclusion criteria and performed a meta-analysis using RevMan5.3.5 software. Forest plots, demonstrating the outcomes of the ERAS group vs the control group after pancreatic surgery, and funnel plots were used to evaluate potential publication bias. Twenty case-control studies including 3694 patients, published between January 1995 and August 2017, were selected for the meta-analysis. This study included the ERAS group ( n = 1886) and the control group ( n = 1808), which adopted the traditional perioperative management. Compared to the control group, the ERAS group had lower delayed gastric emptying rates [odds ratio (OR) = 0.58, 95% confidence interval (CI): 0.48-0.72, P < 0.00001], lower postoperative complication rates (OR = 0.57, 95%CI: 0.45-0.72, P < 0.00001), particularly for the mild postoperative complications (Clavien-Dindo I-II) (OR = 0.71, 95%CI: 0.58-0.88, P = 0.002), lower abdominal infection rates (OR = 0.70, 95%CI: 0.54-0.90, P = 0.006), and shorter postoperative length of hospital stay (PLOS) (WMD = -4.45, 95%CI: -5.99 to -2.91, P < 0.00001). However, there were no significant differences in complications, such as, postoperative pancreatic fistulas, moderate to severe complications (Clavien-Dindo III- V), mortality, readmission and unintended reoperation, in both groups. The perioperative implementation of ERAS programs in pancreatic surgery is safe and effective, can decrease postoperative complication rates, and can promote recovery for patients.

Vascular function is very important for maintaining circulation after cardiac surgery. Circulating microparticles (MPs) generated in various diseases play important roles in causing inflammation, coagulation, and vascular injury. However, the impact of MPs generated from patients who have valvular heart disease (VHD), before and after cardiac surgery, on vascular function remains unknown. This study is designed to investigate the impact of such MPs on vasodilation. Microparticles were isolated from age-matched healthy subjects and patients who had VHD, before cardiac surgery, and at 12 hours and 72 hours afterward. The number of MPs was measured and compared. Effects evaluated were of the impact of MPs on: vasodilation of mice aorta; the phosphorylation and expression of Akt, endothelial nitric oxide synthase (eNOS), protein kinase C-βII (PKC-βII), and p70 ribosomal protein S6 kinase (p70S6K); expression of caveolin-1; the association of eNOS with heat shock protein 90 (HSP90); and generation of nitric oxide and superoxide anion of human umbilical vein endothelial cells. Compared with the healthy subjects, VHD patients had significantly higher levels of circulating MPs and those MPs before cardiac surgery can: impair endothelium-dependent vasodilation; inhibit phosphorylation of Akt and eNOS; increase activation of PKC-βII and p70S6K; enhance expression of caveolin-1; reduce the association of HSP90 with eNOS; decrease nitric oxide production, and increase superoxide anion generation. These deleterious effects were even stronger in postoperative MPs. Our data demonstrate that MPs generated from VHD patients before and after cardiac surgery contributed to endothelial dysfunction, by uncoupling and inhibiting eNOS. Circulating MPs are potential therapeutic targets for the maintenance of vascular function postoperatively. Copyright © 2015 The American Association for Thoracic Surgery. Published by Elsevier Inc.

Superficial temporal artery - middle cerebral artery (STA-MCA) bypass surgery might improve the cerebral blood flow (CBF) but fail to reduce the risk of post-surgical events such as ischaemic stroke. In this study, we studied retrospectively whether the risk of post-surgical events corresponded to the change in resting CBF and/or the change in vasoreactivity observed before and after STA-MCA surgery using N-isopropyl-I-123-p-iodoamphetamine ( 123 I-IMP) brain single-photon emission tomography (SPET). 123 I-IMP brain SPET images obtained at rest and following acetazolamide challenge both before and after STA-MCA surgery were studied in 30 patients. Resting CBF was estimated semiquantitatively using the resting count ratios of the middle cerebral artery (MCA) area to the cerebellum. Acetazolamide challenge was assumed to result in an average increase in flow of 40% in the cerebellum. The vasoreactive response was then estimated as the ratio of the change in counts (acetazolamide - rest) to the resting cerebellar counts multiplied by 1.4. We classified 14 patients (50.5±19.3 years) into group I, who had a change in their resting CBF from before to after surgery of >10%, and 16 patients (54.0±18.8 years) into group II, who had a change in their resting CBF from before to after surgery of ≤10%. Oxygen-15 positron emission tomography (PET) studies were performed in five patients from group I and five patients from group II. One post-surgical event occurred in group I while there were eight post-surgical events in group II (P<0.05). Resting CBF improved by 20.4%±7.5% in group I and by 0.9%±6.9% in group II patients after surgery (P<0.001). No significant difference in the improvement in vasoreactivity was observed between group I patients (32.6%±17.7%) and group II patients (24.6%±15.6%) following surgery. Patients in the group I PET subset showed normalization of oxygen extraction fraction (OEF) from 0.59±0.09 before surgery to 0.46±0.06 after surgery (P<0

The purpose of the study was to implement accelerated partial breast irradiation (APBI) by means of image-guided intensity-modulated radiotherapy (IG-IMRT) following breast-conserving surgery (BCS) for low-risk early invasive breast cancer. Between July 2011 and March 2014, 60 patients with low-risk early invasive (St I-II) breast cancer who underwent BCS were enrolled in our phase II prospective study. Postoperative APBI was given by means of step and shoot IG-IMRT using 4 to 5 fields to a total dose of 36.9 Gy (9×4.1 Gy) using a twice-a-day fractionation. Before each fraction, series of CT images were taken from the region of the target volume using a kV CT on-rail mounted in the treatment room. An image fusion software was used for automatic image registration of the planning and verification CT images. Patient set-up errors were detected in three directions (LAT, LONG, VERT), and inaccuracies were adjusted by automatic movements of the treatment table. Breast cancer related events, acute and late toxicities, and cosmetic results were registered and analysed. At a median follow-up of 24 months (range 12-44) neither locoregional nor distant failure was observed. Grade 1 (G1), G2 erythema, G1 oedema, and G1 and G2 pain occurred in 21 (35%), 2 (3.3%), 23 (38.3%), 6 (10%) and 2 (3.3%) patients, respectively. No G3-4 acute side effects were detected. Among late radiation side effects G1 pigmentation, G1 fibrosis, and G1 fat necrosis occurred in 5 (8.3%), 7 (11.7%), and 2 (3.3%) patients, respectively. No ≥G2 late toxicity was detected. Excellent and good cosmetic outcome was detected in 45 (75%) and 15 (25%) patients. IG-IMRT is a reproducible and feasible technique for the delivery of APBI following conservative surgery for the treatment of low-risk, early-stage invasive breast carcinoma. Preliminary results are promising, early radiation side effects are minimal, and cosmetic results are excellent.

The study included 421 patients who underwent a routine hysterectomy. The patients were divided into 3 groups with respect to analgesic method. The method of multimodal balanced analgesia was used in all cases. Group I patients additionally received epidural analgesia. Group II patients did not receive epidural analgesia (the control group. Group III patients received 600 mg of gabapentin as an adjuvant to opioid analgesia. Results. A significant difference in pain intensity within the first 72 hours after surgery between 3 groups of patients was found. Oral gabapentin as an adjunct to patient-controlled epidural analgesia provided efficient pain relief, reduction in the need for opioid analgesics in the perioperative period, as well as reduction in the incidence of postoperative nausea and vomiting after surgery.

Laryngeal cleft (LC) is a rare congenital anomaly manifesting in a variety of symptoms, including swallowing disorders and aspirations, dyspnea, stridor and hoarseness. The mild forms (types I-II) may be underdiagnosed, leading to protracted symptomatology and morbidity. To evaluate the diagnostic process, clinical course, management and outcome in children with type I-II laryngeal clefts. We conducted a retrospective case analysis for the years 2005-2012 in a tertiary referral center. Seven children were reviewed: five boys and two girls ranging in age from birth to 5 years. The most common presenting symptoms were cough, aspirations and pneumonia. Evaluation procedures included fiber-optic laryngoscopy (FOL), direct laryngoscopy (DL) and videofluoroscopy. Other pathologies were seen in three children. Six children underwent successful endoscopic surgery and one child was treated conservatively. The postoperative clinical course was uneventful in most of the cases. Types I-II LC should be considered in the differential diagnosis of children presenting with protracted cough and aspirations. DL is crucial for establishing the diagnosis. Endoscopic surgery is safe and should be applied promptly when conservative measures fail.

Acute ischemia reperfusion (I/R injury of lower extremities occurs especially when a temporary cross-clamp is applied to the abdominal aorta during aortic surgery. Research regarding the treatment of I/R injury has been increasing day-by-day. In this study, we aimed to investigate the effect of picroside II on skeletal muscle of rats experiencing simulated I/R.Materials and methods: Twenty-four male Wistar albino rats weighing between 210 and 300 g were used in this study. Rats were randomly divided into 4 groups of 6 rats each (control, I/R, control + picroside II, and I/R + picroside II. The infrarenal section of the abdominal aorta was occluded with an atraumatic microvascular clamp in I/R group. The clamp was removed after 120 minutes and reperfusion was provided for a further 120 minutes. Picroside II (10 mg kg–1 was administered intraperitoneally to the animals in control + picroside II and I/R + picroside II groups. At the end of the study, skeletal muscle tissue was obtained for the determination of total oxidant status (TOS and total antioxidant status (TAS levels

High resolution MRI is very important in the evaluations of patients with intractable temporal lobe epilepsy in preoperative investigations. Morphologic abnormalities on cranial MRI usually indicate the epileptogenic focus. Intractable TLE patients who have normal cranial MRI or bilateral hippocampal atrophy may have a chance for surgery if a certain epileptogenic focus is determined. We evaluated the patients who were monitorized in Gazi University Medical Faculty Epilepsy Center from October 1997 to April 2004. Seventy three patients, who had a temporal epileptogenic focus, underwent anterior temporal lobectomy at Ankara University Medical Faculty Department of Neurosurgery. Twelve of them (16, 4%), did not have any localizing structural lesion on cranial MRI. Of the 12 patients examined 6 had normal findings and 6 had bilateral hippocampal atrophy. Of these 12 patients, 6 (50%) were women and 6 (50%) were men. The ages of patients ranged from 7 to 37 (mean: 24.5). Preoperatively long-term scalp video-EEG monitoring, cranial MRI, neuropsychological tests, and Wada test were applied in all patients. Five patients, whose investigations resulted in conflicting data, underwent invasive monitoring by the use of subdural strips. The seizure outcome of patients were classified according to Engel with postsurgical follow-up ranging from 11 to 52 (median: 35.7) months. Nine patients (75%) were classified into Engel's Class I and the other 3 patients (25%) were placed into Engel's Class II. One patient who was classified into Engel's Class II had additional psychiatric problems. The other patient had two different epileptogenic foci independent from each other in her ictal EEG. One of them localized in the right anterior temporal area, the other was in the right frontal lobe. She was classified in Engel's Class II and had no seizure originating from temporal epileptic focus, but few seizures originating from the frontal region continued after the surgery. In conclusion

We aimed to identify prognostic factors affecting clinical outcomes in emergent primary resection. A retrospective analysis of prospectively acquired data of 230 consecutive emergent patients between August 1994 and January 2005 were evaluated in this study. Sixty-nine patients applied with right colon obstruction and 161 patients with left. Resection and primary anastomosis was carried out in 128 patients and resection and stoma in 102 patients. The patients were divided into two cohorts: patients who developed poor outcome within 30 days after surgery and those who did not. Major morbidity or mortality were reported in 60 (26.1%) patients. Analysis revealed that the most important prognostic factors for poor outcome were American Anesthesiology Association (ASA) grade ≥3, Acute Physiology and Chronic Health Evaluation II (APACHE II) score ≥11, age >60 years, presence of peritonitis, and surgery during on-call hours. Age >60 years and on-call surgery were determinant factors in right-sided obstructions, whereas ASA grade ≥3, APACHE II score ≥11, and presence of peritonitis were determinant factors in left-sided obstructions. All these factors but the timing of the operation emphasize the pivotal role of the patient's physiological condition on admission. Accurate preoperative evaluation might predict the clinical outcome and help in establishing the most appropriate treatment.

Surgery or radiation therapy for Stage I and IIA carcinoma of the cervix

International Nuclear Information System (INIS)

Brady, L.W.

1979-01-01

The choice of treatment in carcinoma of the cervix is best decided after careful individual appraisal has been carried out. For best results, a long-term view must be agreed upon initially and careful followup by the same team is obligatory. At present, surgery, radiation therapy, and a combination of these two modalities have been employed successfully to manage carcinoma of the cervix. To a great extent, the facilities, the experience, and the interest of the personnel involved influence the type of therapy that will be employed. Generally speaking, the choice of treatment is determined primarily by the stage of the disease process. Radical surgery in the management of patients with Stage I and Stage II-A carcinoma of the cervix must be planned to include within the en bloc dissection the uterus, tubes, ovaries, and regional lymph node drainage from those organs. Therefore, a radical lymphadnectomy is an integral and important part of the overall management program when radical surgery is performed. In most institutions, radiation therapy is used most frequently to treat carcinoma of the cervix in Stages I and II-A. The data from various institutions indicate significant survival potential from radiation therapy treatment programs that are appropriately devised. In Stages I and II-A the complications are minimal in character (primarily proctitis and cystitis); generally, they involve a potential incidence of about six percent

Full Text Available Purpose: To evaluate the feasibility and stability of ocular alignment after single-stage adjustable strabismus surgery (SSASS performed under topical anesthesia. Materials and Methods: Forty-five patients of concomitant exodeviations were randomized into three groups of 15 cases each and were operated with three different techniques: Group I - conventional surgery, Group II - two-stage adjustable suture technique with suture adjustment performed 6h postoperatively and Group III- SSASS under topical anesthesia and intravenous conscious sedation with midazolam and fentanyl. Intraoperative suture adjustment was done by giving a cross target to the patient on the ceiling at the end of the procedure. Surgical results were compared among the three groups at three months follow-up. Intraoperative hemodynamic parameters and patients′ experience of the surgery (by questionnaire were also compared. Results: Mean preoperative deviation for distance in Groups I, II, III was -41.67 prism diopter (pd ±9.0, -38.93 pd ±11.05 and -41.87 pd ±8.91 ( P =0.6 respectively. At three months, mean correction achieved for distance was +31.87 pd ±11.71, +35.47 pd ±10.86 and +42.80 pd ±10.71 respectively which was significantly different between Group III and Group I ( P =0.03. Intraoperatively all hemodynamic parameters remained stable and comparable ( P =0. 5 in all groups. Intraoperative pain ( P < 0.001 and time taken for surgery ( P < 0.001 was more in the SSASS group. Amount of exodrift was 10-12 pd, comparable in all three groups ( P = 0.5. Conclusions: SSASS, performed under topical anesthesia, is safe and has better outcomes than conventional recession-resection surgery for concomitant exodeviation. An overcorrection of about 10-12 pd is recommended to check the exodrift and achieve stable alignment.

The purpose of our study was to determine the effects of anesthetic technique and ambient temperature on thermoregulation for patients undergoing lower extremity surgery. Our study included 90 male patients aged 18-60 years in American Society of Anesthesiologists Physical Status groups I or II who were scheduled for lower extremity surgery. Patients were randomly divided into three groups according to anesthetic technique: general anesthesia (GA), epidural anesthesia (EA), and femoral-sciatic block (FS). These groups were divided into subgroups according to room temperature: the temperature for group I was 20-22 °C and that for group II was 23-25 °C. Therefore, we labeled the groups as follows: GA I, GA II, EA I, EA II, FS I, and FS II. Probes for measuring tympanic membrane and peripheral temperature were placed in and on the patients, and mean skin temperature (MST) and mean body temperature (MBT) were assessed. Postoperative shivering scores were recorded. During anesthesia, tympanic temperature and MBT decreased whereas MST increased for all patients. There was no significant difference between tympanic temperatures in either the room temperature or anesthetic method groups. MST was lower in group GA I than in group GA II after 5, 10, 15, 20, 60 and 90 min whereas MBT was significantly lower at the basal level (p temperature affected thermoregulation in Group GA.

Full Text Available A workshop of experts from France, Germany, Italy and the United States took place at Humanitas Research Hospital Milan, Italy, on 10-11 February 2016, to examine techniques for and applications of robotic surgery to thoracic oncology. The main topics of presentation and discussion were: robotic surgery for lung resection; robot-assisted thymectomy; minimally invasive surgery for esophageal cancer; new developments in computer-assisted surgery and medical applications of robots; the challenge of costs; and future clinical research in robotic thoracic surgery. The following article summarizes the main contributions to the workshop. The Workshop consensus was that, since video-assisted thoracoscopic surgery (VATS is becoming the mainstream approach to resectable lung cancer in North America and Europe, robotic surgery for thoracic oncology is likely to be embraced by an increasing numbers of thoracic surgeons, since it has technical advantages over VATS, including intuitive movements, tremor filtration, more degrees of manipulative freedom, motion scaling, and high definition stereoscopic vision. These advantages may make robotic surgery more accessible than VATS to trainees and experienced surgeons, and also lead to expanded indications. However the high costs of robotic surgery and absence of tactile feedback remain obstacles to widespread dissemination. A prospective multicentric randomized trial (NCT02804893 to compare robotic and VATS approaches to stage I and II lung cancer will start shortly.

The redefinition of aging in American surgery.

Neuman, Mark D; Bosk, Charles L

2013-06-01

Adults aged sixty-five and over account for a large fraction of all surgeries performed in the United States each year. While historical growth in rates of surgery in this population is commonly attributed to financial incentives and technological innovations, the shifts in thought that underpinned the spread of surgery among the U.S. elderly remain largely unexplored. We examined changing perspectives on aging over time in American surgery through two case studies: the expansion of general surgical procedures among older U.S. adults between 1945 and 1965, and the spread of coronary artery bypass grafting (CABG) among the U.S. elderly between 1975 and 1995. For this article, we used close readings of historical journal articles, textbook excerpts, survey reports, and government documents related to surgery and aging. Similar perspectives on aging informed the spread of both general surgical procedures among older adults after World War II and CABG in the elderly from the mid-1970s onward. In each case, surgeons argued against earlier views that surgery was contraindicated in old age using rhetoric that negated the relevance of age to medical decisions. Furthermore, surgeons elevated other types of information-such as the presence or absence of chronic diseases-to supplant age as an explanation for the high operative mortality rates seen among older patients. By stressing the modifiability of operative risk in the elderly, surgeons' arguments positioned old age itself as a new surgical "frontier." Surgeons' arguments for the expansion of surgery among the U.S. elderly over time worked to negate the relevance of age to medical decisions and to portray the wider use of surgery in the elderly as uniformly beneficial. While potentially promoting broader access to surgical care, such perspectives may also have contributed to ongoing health policy challenges by normalizing surgery at any stage in the life-course, with implications for current patterns of surgical

The success of pharyngeal surgery in the treatment of obstructive sleep apnea syndrome depends on the appropriate selection of patients. To propose a new staging for indication of pharyngeal surgery in obstructive sleep apnea syndrome. A total of 54 patients undergoing extended tonsillectomy were retrospectively included, divided into six stages. Stage I: patients with palatine tonsils grade 3/4 and modified Mallampati index 1/2; stage II: palatine tonsils 3/4 and modified Mallampati index 3/4; stage III: palatine tonsils 1/2 and modified Mallampati index 1/2; stage IV: palatine tonsils 1/2 and modified Mallampati index 3/4; stage V: body mass index ≥40 kg/m(2) with palatine tonsils 3/4 and modified Mallampati index 1, 2, 3, or 4. Stage VI: body mass index ≥40 with palatine tonsils 1/2 and modified Mallampati index 1, 2, 3, or 4. The surgical success rates were 88.9%, 75.0%, 35.7%, 38.5%, and 100.0% in stages I-V. The presence of hypertrophic palatine tonsils was the anatomical factor in common in the most successful stages (I, II, and V), regardless of body mass index. Although the modified Mallampati index classes 3 and 4 reduced the success rate of surgery in patients with hypertrophic tonsils (stage II), the presence of modified Mallampati index classes 1 and 2 did not favor surgical success in patients with normal tonsils (stage III).

Enterogastric reflux and gastric clearance of refluxate in normal subjects and in patients with and without bile vomiting following peptic ulcer surgery

International Nuclear Information System (INIS)

Mackie, C.; Hulks, G.; Cuschieri, A.

1986-01-01

A noninvasive scintigraphic technique was used to estimate enterogastric reflux and subsequent gastric evacuation of refluxate in 35 normal, healthy subjects and 55 patients previously treated by vagotomy or partial gastrectomy. Reflux was provoked by a milk drink and quantitated by counting 99Tcm-EHIDA activity within the gastric area during gamma camera imaging. Seven normal subjects (20%) showed reflux of 5-18% of initial activity (mean: 10%), with peak values occurring at 5-30 minutes (mean: 14 minutes) following the milk. Gastric evacuation of activity in these subjects was monoexponential (r = 0.993, T1/2 = 24.1 minutes). Reflux occurred more frequently than normal in patients with truncal vagotomy and drainage (22/28 patients) and partial gastrectomy (20/21 patients). All of 16 patients with Billroth II anastomoses exhibited reflux, which was excessive compared with refluxing normal subjects (mean: 25%; p less than 0.01) and occurred later into the study (mean: 34 minutes; p less than 0.01). Ten of 11 asymptomatic patients showed reflux of similar amounts of activity (mean: 21%) compared with 16 patients who complained of bile vomiting (mean: 22%). However, asymptomatic patients exhibited gastric evacuation of refluxate at a rate similar to that of refluxing normal subjects, while bile vomiters showed significant gastric retention of refluxate at 25-30 minutes following peak gastric activity (p less than 0.05). This result confirms that post-operative bile vomiting is essentially a problem of gastric emptying

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.

Published studies on laparoscopic surgery for transverse colon cancer are scarce. More studies are necessary to evaluate the feasibility, safety, and long-term oncologic outcomes of laparoscopic surgery for transverse colon cancer. From April 1996 to December 2010, 102 consecutive patients with stage II or III disease who had undergone curative resection for transverse colon cancer were enrolled. Seventy-nine patients underwent laparoscopy-assisted colectomy (LAC), whereas 23 patients underwent conventional open colectomy (OC). Short- and long-term outcomes of the two groups were compared. The OC group had a larger tumor size (7.6 ± 3.4 cm versus 5.2 ± 2.3 cm, P = .004) and more retrieved lymph nodes (26.4 ± 11.6 versus 17.5 ± 9.4, P = .002), without differences in resection margins. In the LAC group, return to diet was faster (4.5 ± 1.2 days versus 5.4 ± 1.8 days, P = .013), and postoperative hospital stay was shorter (12.1 ± 4.2 days versus 15.9 ± 4.8 days, P = .000). There were no differences in occurrence of intra- or postoperative complications. There were no statistically significant differences in overall survival rate (OS) or disease-free survival rate (DFS) between the two groups (5-year OS, 90.4% versus 90.5%, P = .670; 5-year DFS, 84.2% versus 90.7%, P = .463). Laparoscopic surgery for transverse colon cancer has better short-term outcomes compared with open surgery, with acceptable long-term outcomes. As in colorectal cancer of other sites, laparoscopic surgery can be a feasible alternative to conventional surgery for transverse colon cancer.

Orthognathic surgery is widely used to correct dentofacial discrepancies. However, this procedure presents numerous possible complications. The aim of our study is to review intraoperative and postoperative complications related to orthognathic surgery based upon a 10-year period in the Maxillofacial Surgery Department of Federico II University of Naples. Medical records of 423 patients who undergone orthognathic surgery in a 10-year period were retrospectively analyzed and complications was noted. Statistical analysis was conduced in order to understand if the type of surgical procedure influenced complications rate. One hundred eighty-five complications in 143 (33.8%) of the 423 treated patients were reported. Complications detected were nerve injury (49 cases, 11.9%), infections (10 cases, 2.4%), complications related to fixation plates or screws (30 cases, 7.1%), bad split osteotomy (8 cases, 1.9%), secondary temporo-mandibular joint disorders (36 cases, 8.5%), dental injuries (21 cases, 5%), condilar resorption (2 cases, 0.5%), and necessity of a second-time surgery (24 cases, 5.7%). Serious complications seem to be quite rare in orthognathic surgery. Some of the surgical complications found are related to the surgeon experience and not strictly to the risks of the operation itself. Understanding potential complications allows the surgeon to guarantee safe care through early intervention and correctly inform the patient in the preoperative colloquy.

The afferent loop syndrome corresponds to an acute or chronic obstruction of the afferent loop following a partial gastrectomy with Billroth II gastro-jejunal anastomosis. We describe the case of a 77-year-old man with history of partial gastrectomy for peptic ulcer disease performed 31 years ago and currently admitted for jaundice and poor general status. MR imaging showed dilatation of biliary and pancreatic ducts and showed a soft tissue mass between the afferent loop and the residual stomach. Endoscopy showed complete obstruction of the afferent loop by a biopsy-proven adenocarcinoma. The patient died of sepsis shortly after endoscopy of septicemia. (authors)

Myocardial protection in heart surgery.

Science.gov (United States)

Mentzer, Robert M

2011-01-01

One of the unmet clinical needs in heart surgery is the prevention of myocardial stunning and necrosis that occurs as a result of ischemia-reperfusion. Myocardial stunning, a frequent consequence after heart surgery, is characterized by a requirement for postoperative inotropic support despite a technically satisfactory heart operation. In high-risk patients with marginal cardiac reserve, stunning is a major cause of prolonged critical care and may be associated with as much as a 5-fold increase in mortality. In contrast, the frequency of myocardial necrosis (myocardial infarction [MI]) after cardiac surgery is less appreciated and its consequences are much more subtle. The consequences may not be apparent for months to years. While we now have a much better understanding of the molecular mechanisms underlying myocardial stunning and MI, we still have no effective way to prevent these complications, nor a consistently effective means to engage the well-studied endogenous mechanisms of cardioprotection. The failure to develop clinically effective interventions is multifactorial and can be attributed to reliance on findings obtained from subcellular and cellular studies, to drawing conclusions from preclinical large animal studies that have been conducted in a disease-free state, and to accepting less than robust surrogate markers of injury in phase II clinical trials. These factors also explain the disappointing failure to identify effective adjuvant therapy in the setting of percutaneous coronary revascularization for acute MI (AMI) and reperfusion injury. These issues have contributed to the disappointing outcomes of large and costly phase III trials, resulting in a lack of enthusiasm on the part of the pharmaceutical industry to engage in further drug development for this indication. The purpose of this review is to (1) define the scope of the clinical problem; (2) summarize the outcomes of selected phases II and III clinical trials; and (3) identify the gap that

To determine the long-term functional outcomes of type II thyroplasty using titanium bridges for adductor spasmodic dysphonia (AdSD) by perceptual analysis using the Voice Handicap Index-10 (VHI-10) and by acoustic analysis. Fifteen patients with AdSD underwent type II thyroplasty using titanium brides between August 2006 and February 2011. VHI-10 scores, a patient-based survey that quantifies a patient's perception of his or her vocal handicap, were determined before and at least 2 years after surgery. Concurrent with the VHI-10 evaluation, acoustic parameters were assessed, including jitter, shimmer, harmonic-to-noise ratio (HNR), standard deviation of F0 (SDF0), and degree of voice breaks (DVB). The average follow-up interval was 30.1 months. No patient had strangulation of the voice, and all were satisfied with the voice postoperatively. In the perceptual analysis, the mean VHI-10 score improved significantly, from 26.7 to 4.1 two years after surgery. All patients had significantly improved each score of three different aspects of VHI-10, representing improved functional, physical, and emotional well-being. All acoustic parameters improved significantly 2 years after surgery. The treatment of AdSD with type II thyroplasty significantly improved the voice-related quality of life and acoustic parameters 2 years after surgery. The results of the study suggest that type II thyroplasty using titanium bridges provides long-term relief of vocal symptoms in patients with AdSD. Copyright © 2013 Elsevier Ireland Ltd.

The Cerebral Palsy Computerized Adaptive Test (CP-CAT) is a parent-reported outcomes instrument for measuring lower and upper-extremity function, activity, and global health across impairment levels and a broad age range of children with cerebral palsy (CP). This study was performed to examine whether the Lower Extremity/Mobility (LE) CP-CAT detects change in mobility following orthopaedic surgery in children with CP. This multicenter, longitudinal study involved administration of the LE CP-CAT, the Pediatric Outcomes Data Collection Instrument (PODCI) Transfer/Mobility and Sports/Physical Functioning domains, and the Timed "Up & Go" test (TUG) before and after elective orthopaedic surgery in a convenience sample of 255 children, four to twenty years of age, who had CP and a Gross Motor Function Classification System (GMFCS) level of I, II, or III. Standardized response means (SRMs) and 95% confidence intervals (CIs) were calculated for all measures at six, twelve, and twenty-four months following surgery. SRM estimates for the LE CP-CAT were significantly greater than the SRM estimates for the PODCI Transfer/Mobility domain at twelve months, the PODCI Sports/Physical Functioning domain at twelve months, and the TUG at twelve and twenty-four months. When the results for the children at GMFCS levels I, II, and III were grouped together, the improvements in function detected by the LE CP-CAT at twelve and twenty-four months were found to be greater than the changes detected by the PODCI Transfer/Mobility and Sports/Physical Functioning scales. The LE CP-CAT outperformed the PODCI scales for GMFCS levels I and III at both of these follow-up intervals; none of the scales performed well for patients with GMFCS level II. The results of this study showed that the LE CP-CAT displayed superior sensitivity to change than the PODCI and TUG scales after musculoskeletal surgery in children with CP.

OBJECTIVE Majewski osteodysplastic primordial dwarfism Type II (MOPD II) is a rare genetic disorder. Features of it include extremely small stature, severe microcephaly, and normal or near-normal intelligence. Previous studies have found that more than 50% of patients with MOPD II have intracranial vascular anomalies, but few successful surgical revascularization or aneurysm-clipping cases have been reported because of the diminutive arteries and narrow surgical corridors in these patients. Here, the authors report on a large series of patients with MOPD II who underwent surgery for an intracranial vascular anomaly. METHODS In conjunction with an approved prospective registry of patients with MOPD II, a prospectively collected institutional surgical database of children with MOPD II and intracranial vascular anomalies who underwent surgery was analyzed retrospectively to establish long-term outcomes. RESULTS Ten patients with MOPD II underwent surgery between 2005 and 2012; 5 patients had moyamoya disease (MMD), 2 had intracranial aneurysms, and 3 had both MMD and aneurysms. Patients presented with transient ischemic attack (TIA) (n = 2), ischemic stroke (n = 2), intraparenchymal hemorrhage from MMD (n = 1), and aneurysmal subarachnoid hemorrhage (n = 1), and 4 were diagnosed on screening. The mean age of the 8 patients with MMD, all of whom underwent extracranial-intracranial revascularization (14 indirect, 1 direct) was 9 years (range 1-17 years). The mean age of the 5 patients with aneurysms was 15.5 years (range 9-18 years). Two patients experienced postoperative complications (1 transient weakness after clipping, 1 femoral thrombosis that required surgical repair). During a mean follow-up of 5.9 years (range 3-10 years), 3 patients died (1 of subarachnoid hemorrhage, 1 of myocardial infarct, and 1 of respiratory failure), and 1 patient had continued TIAs. All of the surviving patients recovered to their neurological baseline. CONCLUSIONS Patients with MMD

Duodenal phytobezoar, an unusual cause of acute duodenal obstruction, is rarely seen. The most common cause of this type of bezoar is persimmon. It frequently arises from underlying gastrointestinal tract pathologies (gastric surgery, etc.). Here, we report the case of a 66-year-old man who had undergone distal gastrectomy with Billroth I reconstruction for gastric cancer and experienced severe epigastric discomfort, abdominal pain, and vomiting for a few days. The abdominal computed tomography scan showed a large-sized mass in the horizontal portion of the duodenum. On following endoscopic examination, a large phytobezoar was revealed in the duodenum. He was treated with endoscopic fragmentation combined with nasogastric Coca-Cola. The patient tolerated the procedure well and resumed a normal oral diet 3 days later.

Obesity represents a vast and rapidly increasing global burden. Bariatric surgery is the only intervention achieving sustained weight loss, among its wide-ranging benefits. In this article, we describe the growing challenges presented by adolescents with severe obesity and review the literature on surgical and other treatment options. Outcomes in terms of weight loss, metabolic and quality of life improvement, reversal of obstructive sleep apnea, insulin resistance, type II diabetes mellitus, hypertension, and dyslipidemia appear comparable to those seen in adults. However, long-term data on safety and sustainability are lacking. There is a growing acceptance of the need for surgery as a treatment for the morbidly obese adolescent population, and the number of studies reporting outcomes after adolescent bariatric surgery is increasing. Accumulating evidence suggests that the benefits seen in adult bariatric surgery can be reproduced in adolescents. Thus, adolescent bariatric surgery appears to be safe and effective in achieving benefits desired in terms of weight control and improvements in metabolic health and quality of life. However, particular care must be taken when treating a young population, and long-term outcomes are awaited to properly define indications and limitations. © The Finnish Surgical Society 2014.

The optimal surgical approach (wide local excision (WLE) vs. Mohs micrographic surgery (MOHS)) for treating Merkel cell carcinoma (MCC) is yet to be determined. To compare survival outcomes in patients with early stage MCC treated with MOHS versus WLE. A retrospective review of all cases in the National Cancer Data Base (NCDB) of MCC of clinical Stage I-II MCC treated with WLE or MOHS was performed. 1,795 cases of Stage I-II MCC were identified who underwent WLE (N=1,685) or MOHS (N=110). There was no difference in residual tumor on surgical margins between the two treatment groups (p=0.588). On multivariate analysis, there was no difference in overall survival between the treatment modalities (adjusted HR 1.02; 95% CI 0.72-1.45, p=0.897). There was no difference in overall survival between the two groups on propensity score matched analysis. Disease specific survival was not reported as this data in not available in the NCDB. MOHS appears to be as effective as WLE in treating early stage MCC. Copyright © 2018. Published by Elsevier Inc.

Intra-abdominal surgical intervention can cause the development of intra-peritoneal adhesions. To reduce this problem, different agents have been tested to minimize abdominal adhesions; however, the optimal adhesion prophylaxis has not been found so far. Therefore, the A-Part(®) Gel was developed as a barrier to diminish postsurgical adhesions; the aim of this randomized controlled study was a first evaluation of its safety and efficacy. In this prospective, controlled, randomized, patient-blinded, monocenter phase I-II study, 62 patients received either the hydrogel A-Part-Gel(®) as an anti-adhesive barrier or were untreated after primary elective median laparotomy. Primary endpoint was the occurrence of peritonitis and/or wound healing impairment 28 ± 10 days postoperatively. As secondary endpoints anastomotic leakage until 28 days after surgery, adverse events and adhesions were assessed until 3 months postoperatively. A lower rate of wound healing impairment and/or peritonitis was observed in the A-Part Gel(®) group compared to the control group: (6.5 vs. 13.8 %). The difference between the two groups was -7.3%, 90 % confidence interval [-20.1, 5.4 %]. Both treatment groups showed similar frequency of anastomotic leakage but incidence of adverse events and serious adverse events were slightly lower in the A-Part Gel(®) group compared to the control. Adhesion rates were comparable in both groups. A-Part Gel(®) is safe as an adhesion prophylaxis after abdominal wall surgery but no reduction of postoperative peritoneal adhesion could be found in comparison to the control group. This may at least in part be due to the small sample size as well as to the incomplete coverage of the incision due to the used application. NCT00646412.

Directory of Open Access Journals (Sweden)

Paulo Antonio Chiavone

Full Text Available CONTEXT: The high-complexity features of intensive care unit services and the clinical situation of patients themselves render correct prognosis fundamentally important not only for patients, their families and physicians, but also for hospital administrators, fund-providers and controllers. Prognostic indices have been developed for estimating hospital mortality rates for hospitalized patients, based on demographic, physiological and clinical data. OBJECTIVE: The APACHE II system was applied within an intensive care unit to evaluate its ability to predict patient outcome; to compare illness severity with outcomes for clinical and surgical patients; and to compare the recorded result with the predicted death rate. DESIGN: Diagnostic test. SETTING: Clinical and surgical intensive care unit in a tertiary-care teaching hospital. PARTICIPANTS: The study involved 521 consecutive patients admitted to the intensive care unit from July 1998 to June 1999. MAIN MEASUREMENTS: APACHE II score, in-hospital mortality, receiver operating characteristic curve, decision matrices and linear regression analysis. RESULTS: The patients' mean age was 50 ± 19 years and the APACHE II score was 16.7 ± 7.3. There were 166 clinical patients (32%, 173 (33% post-elective surgery patients (33%, and 182 post-emergency surgery patients (35%, thus producing statistically similar proportions. The APACHE II scores for clinical patients (18.5 ± 7.8 were similar to those for non-elective surgery patients (18.6 ± 6.5 and both were greater than for elective surgery patients (13.0 ± 6.3 (p < 0.05. The higher this score was, the higher the mortality rate was (p < 0.05. The predicted death rate was 25.6% and the recorded death rate was 35.5%. Through the use of receiver operating curve analysis, good discrimination was found (area under the curve = 0.80. From the 2 x 2 decision matrix, 72.2% of patients were correctly classified (sensitivity = 35.1%; specificity = 92.6%. Linear

Focal Cortical Dysplasias (FCDs) represent a common architectural cortical disorder underlying drug-resistant focal epilepsy. So far, studies aimed at evaluating whether age at surgery is a factor influencing surgical outcome are lacking, so that data on the comparison between patients harboring Type II FCD operated at younger age and those operated at adult age are still scarce. We compared presurgical clinical features and surgical outcomes of patients with histopathologically diagnosed Type II FCD undergoing surgery at an earlier age with those operated after 20 years of age. We retrospectively analyzed 1660 consecutive patients operated at the "Claudio Munari" Epilepsy Surgery Centre. There were 289 patients (17.4%) with a neuropathological diagnosis of Type II FCD. We included two different groups of patients, the first one including patients operated on at less than 6years, the second sharing the same seizure onset age but with delayed surgery, carried out after the age of 20. Seizure characteristics and, neuropsychological and postoperative seizure outcomes were evaluated by study group. Forty patients underwent surgery before the age of 6 and 66 patients after the age of 20. Surgical outcome was favorable in the whole population (72.6% were classified in Engel's Class Ia+Ic), independently from age at surgery. In the children group, 32 patients were classified in Class I, including 30 (75%) children in classes Ia and Ic. In the adult group, 53 belonged to Class I of whom 47 (71%) were in classes Ia and Ic. The percentage of permanent complications, the surgical outcomes, and AED withdrawal did not significantly differ by study group. Our results indicate that there is no difference between the groups, suggesting that outcome depends mainly on the histological findings and not on timing of surgery. Copyright © 2017 Elsevier Inc.

In nonrandomized trials, neoadjuvant treatment was reported to prolong survival in patients with pancreatic cancer. As neoadjuvant chemoradiation is established for the treatment of rectal cancer we examined the value of neoadjuvant chemoradiotherapy in pancreatic cancer in a randomized phase II trial. Radiological staging defining resectability was basic information prior to randomization in contrast to adjuvant therapy trials resting on pathological staging. Patients with resectable adenocarcinoma of the pancreatic head were randomized to primary surgery (Arm A) or neoadjuvant chemoradiotherapy followed by surgery (Arm B), which was followed by adjuvant chemotherapy in both arms. A total of 254 patients were required to detect a 4.33-month improvement in median overall survival (mOS). The trial was stopped after 73 patients; 66 patients were eligible for analysis. Twenty nine of 33 allocated patients received chemoradiotherapy. Radiotherapy was completed in all patients. Chemotherapy was changed in 3 patients due to toxicity. Tumor resection was performed in 23 vs. 19 patients (A vs. B). The R0 resection rate was 48 % (A) and 52 % (B, P = 0.81) and (y)pN0 was 30 % (A) vs. 39 % (B, P = 0.44), respectively. Postoperative complications were comparable in both groups. mOS was 14.4 vs. 17.4 months (A vs. B; intention-to-treat analysis; P = 0.96). After tumor resection, mOS was 18.9 vs. 25.0 months (A vs. B; P = 0.79). This worldwide first randomized trial for neoadjuvant chemoradiotherapy in pancreatic cancer showed that neoadjuvant chemoradiation is safe with respect to toxicity, perioperative morbidity, and mortality. Nevertheless, the trial was terminated early due to slow recruiting and the results were not significant. ISRCTN78805636; NCT00335543. (orig.)

Full Text Available Introduction: Despite recent advances in anesthesia, cardiopulmonary bypass and surgical techniques, children undergoing congenital heart surgery require postoperativemechanical ventilation. Early extubation was definedas ventilation shorter than 12 hours. Aim of this study is to identify factors associated with successful early extubation after pediatric cardiac surgery.Methods: The study was performed during period from January 2006 to January 2011 at Pediatric Clinic and Heart Center University Clinical center Sarajevo. One hundred children up to 5 years of age, who have had congenital heart disease, with left–right shunt and obstructive heart disease were included in the study. Patients were divided into two groups: Group I - patients extubated within 12 hours after surgery and Group II - patients extubated 12 or more hours after surgery. Results: The most frequently encountered preoperative variables were age with odds ratio 4% 95%CI (1-7%, Down's syndrome 8.5 95%CI (1.6-43.15, failure to thrive 4.3 95%CI( 1-18. Statistically significant postoperative data included lung disease (reactive airways, pneumonia, atelectasis, pneumothorax and with odds ratio 35.1 95 %CI (4-286 and blood transfusion with odds ratio 4.6 95%CI (2-12. Blood transfusion (p=0.002 (Wald=9.2 95%CI (2-12, during as well as after operation procedure has statistically significant influence on prediction time of extubation. Proven markers were age with cut of 21.5 months (sensitivity 74% and specificity 70% and extracorporeal circulation (ECC with cut-of 45.5 minutes (sensitivity 71% and specificity 65%.Conclusion: Early extubation is possible in many children undergoing congenital heart surgery. Younger age and prolonged ECC time are markers associated with prolonged mechanical ventilation.

Integration of robotic surgery into routine practice and impacts on communication, collaboration, and decision making: a realist process evaluation protocol

Science.gov (United States)

2014-01-01

Background Robotic surgery offers many potential benefits for patients. While an increasing number of healthcare providers are purchasing surgical robots, there are reports that the technology is failing to be introduced into routine practice. Additionally, in robotic surgery, the surgeon is physically separated from the patient and the rest of the team, with the potential to negatively impact teamwork in the operating theatre. The aim of this study is to ascertain: how and under what circumstances robotic surgery is effectively introduced into routine practice; and how and under what circumstances robotic surgery impacts teamwork, communication and decision making, and subsequent patient outcomes. Methods and design We will undertake a process evaluation alongside a randomised controlled trial comparing laparoscopic and robotic surgery for the curative treatment of rectal cancer. Realist evaluation provides an overall framework for the study. The study will be in three phases. In Phase I, grey literature will be reviewed to identify stakeholders’ theories concerning how robotic surgery becomes embedded into surgical practice and its impacts. These theories will be refined and added to through interviews conducted across English hospitals that are using robotic surgery for rectal cancer resection with staff at different levels of the organisation, along with a review of documentation associated with the introduction of robotic surgery. In Phase II, a multi-site case study will be conducted across four English hospitals to test and refine the candidate theories. Data will be collected using multiple methods: the structured observation tool OTAS (Observational Teamwork Assessment for Surgery); video recordings of operations; ethnographic observation; and interviews. In Phase III, interviews will be conducted at the four case sites with staff representing a range of surgical disciplines, to assess the extent to which the results of Phase II are generalisable and to

OBJECTIVE In this study, the authors investigated long-term clinical and visual outcomes of patients after occipital lobe epilepsy (OLE) surgery and analyzed the relationship between visual cortical resection and visual function after OLE surgery. METHODS A total of 42 consecutive patients who were diagnosed with OLE and underwent occipital lobe resection between June 1995 and November 2013 were included. Clinical, radiological, and histopathological data were reviewed retrospectively. Seizure outcomes were categorized according to the Engel classification. Visual function after surgery was assessed using the National Eye Institute Visual Functioning Questionnaire 25. The relationship between the resected area of the visual cortex and visual function was demonstrated by multivariate linear regression models. RESULTS After a mean follow-up period of 102.2 months, 27 (64.3%) patients were seizure free, and 6 (14.3%) patients had an Engel Class II outcome. Nineteen (57.6%) of 33 patients had a normal visual field or quadrantanopia after surgery (normal and quadrantanopia groups). Patients in the normal and quadrantanopia groups had better vision-related quality of life than those in the hemianopsia group. The resection of lateral occipital areas 1 and 2 of the occipital lobe was significantly associated with difficulties in general vision, peripheral vision, and vision-specific roles. In addition, the resection of intraparietal sulcus 3 or 4 was significantly associated with decreased social functioning. CONCLUSIONS The authors found a favorable seizure control rate (Engel Class I or II) of 78.6%, and 57.6% of the subjects had good visual function (normal vision or quadrantanopia) after OLE surgery. Lateral occipital cortical resection had a significant effect on visual function despite preservation of the visual field.

BACKGROUND: A relationship between patients with a genetic predisposition to and those who develop postoperative delirium has not been yet determined. The aim of this study was to determine whether there is an association between apolipoprotein E epsilon 4 allele (APOE4) and delirium after major surgery. METHODS: Of 230 intensive care patients admitted to the post anesthesia care unit (PACU) over a period of 3 months, 173 were enrolled in the study. Patients' demographics and intra- and postoperative data were collected. Patients were followed for the development of delirium using the Intensive Care Delirium Screening Checklist, and DNA was obtained at PACU admission to determine apolipoprotein E genotype. RESULTS: Fifteen percent of patients developed delirium after surgery. Twenty-four patients had one copy of APOE4. The presence of APOE4 was not associated with an increased risk of early postoperative delirium (4% vs. 17%; P = 0.088). The presence of APOE4 was not associated with differences in any studied variables. Multivariate analysis identified age [odds ratio (OR) 9.3, 95% confidence interval (CI) 2.0-43.0, P = 0.004 for age ≥65 years), congestive heart disease (OR 6.2, 95% CI 2.0-19.3, P = 0.002), and emergency surgery (OR 59.7, 95% CI 6.7-530.5, P < 0.001) as independent predictors for development of delirium. The Simplified Acute Physiology Score II (SAPS II) and The Acute Physiology and Chronic Health Evaluation II (APACHE II) were significantly higher in patients with delirium (P < 0.001 and 0.008, respectively). Hospital mortality rates of these patients was higher and they had a longer median PACU stay. CONCLUSIONS: Apolipoprotein e4 carrier status was not associated with an increased risk for early postoperative delirium. Age, congestive heart failure, and emergency surgery were independent risk factors for the development of delirium after major surgery.

Bibliometric study of current literature. To catalog the most important minimally invasive spine (MIS) surgery articles using the amount of citations as a marker of relevance. MIS surgery is a relatively new tool used by spinal surgeons. There is a dynamic and evolving field of research related to MIS techniques, clinical outcomes, and basic science research. To date, there is no comprehensive review of the most cited articles related to MIS surgery. A systematic search was performed over three widely used literature databases: Web of Science, Scopus, and Google Scholar. There were four searches performed using the terms "minimally invasive spine surgery," "endoscopic spine surgery," "percutaneous spinal surgery," and "lateral interbody surgery." The amount of citations included was averaged amongst the three databases to rank each article. The query of the three databases was performed in November 2015. Fifty articles were selected based upon the amount of citations each averaged amongst the three databases. The most cited article was titled "Extreme Lateral Interbody Fusion (XLIF): a novel surgical technique for anterior lumbar interbody fusion" by Ozgur et al and was credited with 447, 239, and 279 citations in Google Scholar, Web of Science, and Scopus, respectively. Citations ranged from 27 to 239 for Web of Science, 60 to 279 for Scopus, and 104 to 462 for Google Scholar. There was a large variety of articles written spanning over 14 different topics with the majority dealing with clinical outcomes related to MIS surgery. The majority of the most cited articles were level III and level IV studies. This is likely due to the relatively recent nature of technological advances in the field. Furthermore level I and level II studies are required in MIS surgery in the years ahead. 5.

To evaluate the effect of severe malocclusion requiring orthognathic surgery on the self-esteem (SE) and quality of life (QOL) of female adult patients undergoing orthognathic surgery compared with a group with minor malocclusions seeking only orthodontic treatment. Female patients, aged 18 to 30 years, who had presented for an orthodontic consultation for correction of a malocclusion were enrolled during an 18-month period. In group 1, all the patients required 2-jaw surgery, and they were subdivided into those with a Class II or Class III malocclusion. This group was further subdivided into those with and without clinically significant asymmetry. A second comparison group was selected. These patients had minor malocclusion. Group 2 (the minor malocclusion group; MMG) included patients with a Class I molar relationship with less than 5 mm on the irregularity index in the upper anterior teeth. Each participant completed the Rosenberg's self-esteem scale (RSE) and the Orthognathic Quality of Life Questionnaire (OQLQ) before starting treatment. The RSE and OQLQ measurements were compared using 1-way analysis of variance and Scheffe's multiple comparison. The level of statistical significance was set at P < .05. The MMG group (n = 52) showed significantly better RSE and OQOL values compared with those with Class II (n = 37) and Class III (n = 47) malocclusion (P < .01). In the OQLQ measurements, the social aspects, aesthetics, and oral function scores were also better in the MMG group (P < .01). Only the awareness component did not reveal a significant difference. No significant differences were found in QOL or SE between those with Class II and Class III malocclusion. The influence of asymmetry on the RSE and OQLQ results was not significant in the Class II and III patients. Female adult orthognathic patients showed significant impairments in QOL and SE compared with those with mild malocclusion. Copyright © 2016 The American Association of Oral and

Pressure ulcers are an important perioperatory care quality indicator This is a longitudinal case series study, performed with the following objectives: to estimate the incidence of pressure ulcers in patients submitted to medium and large surgeries; rate them according to the stage and location; verify the association with the variables: gender, age, body mass index (BMI), co-morbidities, surgical position, duration of surgery, anesthesia type and use of positioning devices, with presence or absence of pressure ulcers. Data collection took place in 2007 in São Paulo, with 199 patients, 20.6% of which presented pressure ulcers, and most (98.6%) in stages I and II, and the main location was the trunk (35.1%). The variables: position, surgery time, general anesthesia, and device use had a statistically significant association. In conclusion, there is a high incidence of pressure ulcers among surgical patients, requiring actions aimed at reducing this type of injury.

The role of laparoscopic surgery in management of transverse and descending colon cancer remains controversial. The aim of the present study is to investigate the short-term and oncologic long-term outcomes associated with laparoscopic surgery for transverse and descending colon cancer. This cohort study analyzed 245 patients (stage II disease, n = 70; stage III disease, n = 63) who underwent resection of transverse and descending colon cancers, including 200 laparoscopic surgeries (LAC) and 45 conventional open surgeries (OC) from December 1996 to December 2010. Short-term and oncologic long-term outcomes were recorded. The operative time was longer in the LAC group than in the OC group. However, intraoperative blood loss was significantly lower and postoperative recovery time was significantly shorter in the LAC group than in the OC group. The 5-year overall and disease-free survival rates for patients with stage II were 84.9% and 84.9% in the OC group and 93.7% and 90.0% in the LAC group, respectively. The 5-year overall and disease-free survival rates for patients with stage III disease were 63.4% and 54.6% in the OC group and 66.7% and 56.9% in the LAC group, respectively. Use of laparoscopic surgery resulted in acceptable short-term and oncologic outcomes in patients with advanced transverse and descending colon cancer.

Most regional anesthesia in breast surgeries is performed as postoperative pain management under general anesthesia, and not as the primary anesthesia. Regional anesthesia has very few cardiovascular or pulmonary side-effects, as compared with general anesthesia. Pectoral nerve block is a relatively new technique, with fewer complications than other regional anesthesia. We performed Pecs I and Pec II block simultaneously as primary anesthesia under moderate sedation with dexmedetomidine for breast conserving surgery in a 49-year-old female patient with invasive ductal carcinoma. Block was uneventful and showed no complications. Thus, Pecs block with sedation could be an alternative to general anesthesia for breast surgeries.

Transcatheter mitral valve-in-valve/valve-in-ring procedures (TM-VIVoR) are increasing. The authors aimed to identify independent predictors for hospital mortality in redo mitral valve surgery as possible future selection criteria for TM-VIVoR. Retrospective multicenter registry. Tertiary university and community hospitals. Two-hundred and sixty patients (out of 920 enrolled) who are potentially candidates for TM-VIVoR undergoing redo-surgery. Redo mitral surgery. Regression analyzes and receiver operating characteristic (ROC) curves identified independent predictors of death. Patients potentially candidates for TM-VIVoR reported significant hospital mortality (9.2%; EuroSCORE II: 13.2 ± 13.1, Society of Thoracic Surgeons [STS] score: 6.2 ± 3.1) and major morbidity (3.8% acute myocardial infarction, 5% stroke, 16.9% perioperative respiratory failure, 16.5% acute renal insufficiency, 25% massive transfusions). EuroSCORE II (odds ration [OR] 1.06; confidence interval [CI] 1.01-1.10; p = 0.005), STS score (OR 1.58; CI 1.27-1.97; p = 0.001), age at surgery (OR 1.05; CI 1.00-1.15; p = 0.05), preoperative dialysis (OR 2.5; CI 1.8-12.6; p = 0.042), left ventricular ejection fraction (LVEF) 13.1; 70.8% sensitivity and 68.2% specificity) and better prediction for STS score (AUC: 0.81; cut-off value: 7.4; 75.0% sensitivity and 66.2% specificity). Quintiles stratification identified EuroSCORE II ≥18.7 (5th quintile, observed mortality: 19.3%) and STS score >9.1 as strong predictors of death within each risk-categorization (OR 5.9 and 12.1, respectively). High EuroSCORE II and STS scores, advanced age at surgery, LVEF indications for TM-VIVoR in the redo-mitral surgery scenario. Copyright © 2017 Elsevier Inc. All rights reserved.

ABSTRACT: BACKGROUND: Emergency abdominal surgery carries a 15% to 20% short-term mortality rate. Postoperative medical complications are strongly associated with increased mortality. Recent research suggests that timely recognition and effective management of complications may reduce mortality....... The aim of the present trial is to evaluate the effect of postoperative intermediate care following emergency major abdominal surgery in high-risk patients.Methods and design: The InCare trial is a randomised, parallel-group, non-blinded clinical trial with 1:1 allocation. Patients undergoing emergency...... laparotomy or laparoscopic surgery with a perioperative Acute Physiology and Chronic Health Evaluation II score of 10 or above, who are ready to be transferred to the surgical ward within 24 h of surgery are allocated to either intermediate care for 48 h, or surgical ward care. The primary outcome measure...

Iron absorption after antrectomy with gastroduodenostomy

Magnusson, B.E.O.

1976-01-01

Haematological values were studied in 177 unselected patients 3-6 years after antrectomy with gastroduodenostomy. The majority (76%) had been operated upon for duodenal ulcer, 20% for gastric ulcer and the remaining patients had had both a duodenal and a gastric ulcer before the operation. In 65 patients a vagotomy had been added to the resection. 10% of the males and 15% of the females had a haemoglobin concentration below 13.0 or 12.0 g/100 ml, respectively. The corresponding frequencies for iron defifiency, defined as absence or only traces of haemosiderin in bone marrow smears, were 7% and 15%. The absorption of a small test dose of inorganic iron (0.56 mg Fe ++ as ferrous ascorbate) was studied in all the antrectomized patients. The absorption was also investigated in normal men and in patients who had had a Billroth II partial gastrectomy. No malabsorption of inorganic iron could be found in any of the groups. An inverse relationship between iron absorption and the grading of haemosiderin in bone marrow smears was found in normal subjects as well as in operated patients. Thus, an adequate increase of the absorption of ferrous iron was found even in operated patients with iron deficiency. Gastric acid secretion, measured as the peak acid output (PAO) after stimulation, was determined in all antrectomized patients. In patients having the same grading of haemosiderin (grade II) a slight but significant positive correlation was found between PAO and the absorption from the test dose (Fe ++ ). The absorption of food iron from a composite meal and the absorption from an iron salt (3.0 mg Fe ++ as ferrous ascorbate) was studied in 4 different groups: 1) normal males, 2) non-operated patients with peptic ulcer, 3) antrectomized patients with gastroduodenostomy and 4) patients operated upon with Billroth II partial gastrectomy. The range and mean absorption values from the test dose of inorganic iron were about the same in all groups. The absorption of food iron

The aim of this study was to review the feasibility of selective sentinel lymph node biopsy in patients with previous surgery for breast cancer, as well as to examine the factors that may interfere with sentinel node detection. A retrospective review was performed on 91 patients with breast cancer and previous breast surgery, and who underwent sentinel lymph node biopsy. Patients were divided into two groups according to their previous treatment: aesthetic breast surgery in 30 patients (group I) and breast-conserving surgery in 61 (group II). Lymphoscintigraphy was performed after an intra-tumour injection in 21 cases and a peri-areolar injection in 70 cases. An analysis was made of lymphatic drainage patterns and overall sentinel node detection according to clinical, pathological and surgical variables. The overall detection of the sentinel lymph node in the lymphoscintigraphy was 92.3%, with 7.7% of extra-axillary drainages. The identification rate was similar after aesthetic breast surgery (93.3%) and breast-conserving surgery (91.8%). Sentinel lymph nodes were found in the contralateral axilla in two patients (2.2%), and they were included in the histopathology study. The non-identification rate in the lymphoscintigraphy was 7.7%. There was a significantly higher non-detection rate in the highest histological grade tumours (28.6% grade III, 4.5% grade I and 3.6% grade II). Sentinel lymph node biopsy in patients with previous breast surgery is feasible and deserves further studies to assess the influence of different aspects in sentinel node detection in this clinical scenario. A high histological grade was significantly associated with a lower detection. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

1988-01-01

A retrospective analysis was performed of 118 surgically treated mammary recurrences, occurring following primary conservative excision and radiation therapy for clinical Stages I and II breast cancer. Actuarial cancer-specific survival following salvage surgery was 72% at 5 years and 58% at 10 years. With a median followup of 7 years, further local-regional recurrences were observed in 20 of the 118 patients, many of whom could be treated by further surgery. Actuarial survival after recurrence was significantly influenced by initial clinical stage, as well as by the disease-free interval following primary therapy, but was similar for both premenopausal and postmenopausal patients and for patients treated by radical or breast-conserving salvage operations. For recurrences after the fifth year, actuarial survival following salvage surgery was 83% and 68% at 5 and 10 years, respectively. Survival for Stage I patients was favorable regardless of disease-free interval. It is concluded that recurrences in the breast following primary treatment with limited surgery and irradiation have a considerably more favorable prognosis than that of local failures after primary radical surgery. Suggestions for the management of these recurrences are presented

International Nuclear Information System (INIS)

Maingon, P.; Belichard, C.; Horiot, J.C.; Barillot, I.; Fraisse, J.; Collin, F.

1996-01-01

The AIM of this retrospective study is to analyse the indications and the results of treatment of endometrial carcinomas by preoperative radiotherapy. MATERIAL: From 1976 to 1995, 183 patients FIGO stage I or II were treated by preoperative radiotherapy consisting in 95 cases of external radiotherapy (XRT) and brachytherapy (BT) followed by surgery (S) and, in 88 cases of BT alone before surgery, XRT was indicated in cases of grade 2 or 3 and/or cervical involvement. METHODS: XRT was delivered with a 4-fields technique to 40 Gy in 20 fractions with a medial shielding at 30 Gy. BT was done with low dose rate Cs137 and Fletcher-Suit-Delclos applicators with two intra-uterine tubes and vaginal ovoieds. Complications were scored using the French-Italian syllabus. RESULTS: Five-year actuarial survival rates per stage are: Ia=91%, Ib=83%, II=71%, and per grade: G1=80%, G2=79%, G3=90%. Failures were pelvic in 5/183 (2.7%), vaginal in 4 cases (2%) and nodal in 2 cases (1%). Twelve patients developed metastases (6.5%). Complications were analysed during the radiotherapy, after the surgery and with unlimited follow-up. After BT/S, 12 grade 1, 1 grade 2 and 1 grade 3 complications were observed. In the group of patients treated by RT/BT/S, 22 grade 1, 11 grade 2, 4 grade 3 occurred. There is no statistical correlation between complications and parameters of treatment (XRT, hwt, HWT, reference dose to the bladder and rectum, dose rate of brachytherapy). SUMMARY: Preoperative irradiation is an effective and safe treatment of high risk stage I/II endometrial carcinomas. Results seem independent of the pathology grade

The role of high-frequency oscillations in epilepsy surgery planning.

Epilepsy is a serious brain disorder characterized by recurrent unprovoked seizures. Approximately two-thirds of seizures can be controlled with antiepileptic medications (Kwan 2000). For some of the others, surgery can completely eliminate or significantly reduce the occurrence of disabling seizures. Localization of epileptogenic areas for resective surgery is far from perfect, and new tools are being investigated to more accurately localize the epileptogenic zone (the zone of the brain where the seizures begin) and improve the likelihood of freedom from postsurgical seizures. Recordings of pathological high-frequency oscillations (HFOs) may be one such tool. To assess the ability of HFOs to improve the outcomes of epilepsy surgery by helping to identify more accurately the epileptogenic areas of the brain. For the latest update, we searched the Cochrane Epilepsy Group Specialized Register (25 July 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online (CRSO, 25 July 2016), MEDLINE (Ovid, 1946 to 25 July 2016), CINAHL Plus (EBSCOhost, 25 July 2016), Web of Science (Thomson Reuters, 25 July 2016), ClinicalTrials.gov (25 July 2016), and the World Health Organization International Clinical Trials Registry Platform ICTRP (25 July 2016). We included studies that provided information on the outcomes of epilepsy surgery for at least six months and which used high-frequency oscillations in making decisions about epilepsy surgery. The primary outcome of the review was the Engel Class Outcome System (class I = no disabling seizures, II = rare disabling seizures, III = worthwhile improvement, IV = no worthwhile improvement). Secondary outcomes were responder rate, International League Against Epilepsy (ILAE) epilepsy surgery outcome, frequency of adverse events from any source and quality of life outcomes. We intended to analyse outcomes via an aggregated data fixed-effect model meta-analysis. Two studies representing

To prospectively validate the SYNTAX Score II and forecast the outcomes of the randomized Evaluation of the Xience Everolimus-Eluting Stent Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) Trial. Evaluation of the Xience Everolimus Eluting Stent vs. Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization is a prospective, randomized multicenter trial designed to establish the efficacy and safety of percutaneous coronary intervention (PCI) with the everolimus-eluting stent compared with coronary artery bypass graft (CABG) surgery in subjects with unprotected left-main coronary artery (ULMCA) disease and low-intermediate anatomical SYNTAX scores (EXCEL, the SYNTAX Score II was prospectively applied to predict 4-year mortality in the CABG and PCI arms. The 95% prediction intervals (PIs) for mortality were computed using simulation with bootstrap resampling (10 000 times). For the entire study cohort, the 4-year predicted mortalities were 8.5 and 10.5% in the PCI and CABG arms, respectively [odds ratios (OR) 0.79; 95% PI 0.43-1.50). In subjects with low (≤22) anatomical SYNTAX scores, the predicted OR was 0.69 (95% PI 0.34-1.45); in intermediate anatomical SYNTAX scores (23-32), the predicted OR was 0.93 (95% PI 0.53-1.62). Based on 4-year mortality predictions in EXCEL, clinical characteristics shifted long-term mortality predictions either in favour of PCI (older age, male gender and COPD) or CABG (younger age, lower creatinine clearance, female gender, reduced left ventricular ejection fraction). The SYNTAX Score II indicates at least an equipoise for long-term mortality between CABG and PCI in subjects with ULMCA disease up to an intermediate anatomical complexity. Both anatomical and clinical characteristics had a clear impact on long-term mortality predictions and decision making between CABG and PCI. Published on behalf of the European Society of Cardiology.

Natarajan, S K; Chua, D; Anbalakan, K; Shelat, V G

2017-10-01

Marginal ulcer (MU) is defined as ulcer on the jejunal side of the gastrojejunostomy (GJ) anastomosis. Most MUs are managed medically but those with complications like bleeding or perforation require intervention. It is recommended that GJ anastomosis be revised in patients with MU perforation (MUP). The aim of this case series is to study the clinical presentation and management of MUP. Three hundred and thirty-two patients who underwent emergency surgery for perforated peptic ulcer at a single center were studied over a period of 5 years. Nine patients (2.7 %) presented with MUP. GJ was previously done for either complicated peptic ulcer (n = 4) or for suspected gastric malignancy (n = 5). Two patients had previously completed H. pylori therapy. None of the patients presented with septic shock. MU was on the jejunal side of GJ in all patients. The median MUP size was 10 mm. Four patients (44.4 %) had omental patch repair, three (33.3 %) had primary closure, and one each had revision of GJ and jejunal serosal patch repair. There were no leaks, intra-abdominal abscess or reoperation and no malignancies. MUP patients do not present with septic shock. Omental patch repair or primary closure is sufficient enough. Revision of Billroth-II-GJ into Roux-en-Y-GJ is not mandatory.

Full Text Available The objective of this study was to evaluate the effectiveness of acute normovolemic hemodilution (ANH as a sole method of reducing allogenic blood requirement in patients undergoing primary elective valve surgery. One hundred eighty eight patients undergoing primary elective valve surgery were prospectively randomized into two groups: Group I (n=100 acted as control and in Group II (n=88 autologous blood was removed (10% of estimated blood volume in patients with hemoglobin (Hb > 12g% and 7% when the Hb was < 12g% in the pre-cardiopulmonary bypass (CPB period for subsequent re-transfusion after protamine administration. The autologous blood withdrawn was replaced simultaneously with an equal volume of hydroxyl-ethyl starch solution. Banked blood was transfused in both the groups when Hb was ≤6g % on CPB and ≤8g% after CPB. Platelets were transfused when the count fell to < 100´10 9 /L and fresh frozen plasma (FFP was transfused whenever there was diffuse bleeding with laboratory evidence of coagulopathy. The two groups were comparable as regards demographic data, type of surgical procedures performed, duration of CPB and ischemia, duration of elective ventilation and re-exploration for excessive bleeding. The autologous blood withdrawn in patients with Hb≥12g% was 288.3±69.4 mL and 244.4±41.3 mL with Hb < 12g% (P=NS. The Hb concentration (g % was comparable pre-operatively (Group I= 12.1±1.6, Group II= 12.4±1.4, on postoperative day 1 (Group I =10.3±1.1, Group II= 10.6±1.2 and day 7 (Group I = 10.9±1.5, Group II=10.4±1.5. However, the lowest Hb recorded on CPB was significantly lower in Group II (Group I =7.7±1.2, Group II=6.7±0.9, P < 0.05. There was no difference in the chest tube drainage (Group I =747.2±276.5 mL, Group II=527.6±399.5 mL, blood transfusion (Group I=1.1±1.0 units vs. Group II=1.3±1.0 units intra-operatively and Group I=1.7±1.2 units vs. Group II=1.7±1.4 units post-operatively and FFP transfusion (Group I

We aimed to evaluate (i) the effectiveness of combined surgery (coronary artery bypass grafting with restrictive mitral valve annuloplasty) and (ii) the late gadolinium enhancement cardiovascular magnetic resonance-based predictors of ischaemic mitral regurgitation (IMR) recurrence. The prospective analysis included 40 patients with multivessel coronary artery disease, IMR >II° and left ventricular (LV) dysfunction undergoing combined surgery. The degree of IMR and LV parameters were assessed preoperatively by transthoracic echocardiography, 3D transoesophageal echocardiography and cardiovascular magnetic resonance and postoperatively by transthoracic echocardiography. The effective mitral valve repair group (n = 30) was defined as having recurrent ischaemic mitral regurgitation (RIMR) ≤II° at the end of follow-up (25 ± 11 months). The surgery was effective: freedom from RIMR >II° at 1 and 2 years after surgery was 80% and 75%, respectively. Using multivariable logistic regression, 2 independent predictors of RIMR >II° were identified: ≥3 non-viable LV segments (odds ratio 22, P = 0.027) and ≥1 non-viable segment in the LV posterior wall (odds ratio 11, P = 0.026). Using classification trees, the best combinations of cardiovascular magnetic resonance-based and 3D transoesophageal echocardiography-based predictors for RIMR >II° were (i) posterior mitral valve leaflet angle >40° and LV end-systolic volume index >45 ml/m2 (sensitivity 100%, specificity 89%) and (ii) scar transmurality >68% in the inferior LV wall and EuroSCORE II >8 (sensitivity 83%, specificity 78%). There is a clear relationship between the amount of non-viable LV segments, especially in the LV posterior and inferior walls, and the recurrence of IMR after the combined surgery.

The objective of this work was to investigate the possible relationship between perceived family support, levels of cortisol and post surgery recovery. The study sample comprised 42 patients that were due to undergo open cholecystectomy surgery in a Regional Health Authority Reference Centre of the Autonomous Community of Extremadura in Spain. The FACES-II questionnaire was used for the evaluation of perceived family support and to measure the three fundamental dimensions of perceived family behaviour: cohesion, adaptability and family type. The day before surgery, a sample of saliva was taken from each subject in order to determine the level of cortisol. Results showed a clear relationship between family support and recovery. Patients with higher scores on the Cohesion Scale demonstrated better post surgery recovery (F = 8.8; gl = 40; p = .005). A relationship between levels of cortisol, perceived family support and recovery was also revealed. Patients with lower scores on the Cohesion scale and higher cortisol levels demonstrated poorer post surgery recovery (F = 10.96; gl = 40; p = .006). These results are coherent with other studies that have highlighted the beneficial effects of perceived family support on mental and physical health.

The Plastic Surgery In-Service Training Exam is written by the American Society of Plastic Surgeons. Examinees reasonably infer that tested material reflects the Society's vision for the core curriculum in plastic surgery. The purpose of this study was to determine the levels of evidence on which credited answers to the examination questions are based. Two recent Plastic Surgery In-Service Training Exams (2014 and 2015) were analyzed. Questions were categorized using a taxonomy model. Recommended journal article references for Level III (decision-making) questions were assigned a level of evidence. Exam sections were analyzed for differences in question taxonomy distribution and level of evidence. To look for studies with higher levels of evidence, a PubMed search was conducted for a random sample of 10 questions from each section. One hundred three Level I (25.8 percent), 138 Level II (34.5 percent), and 159 Level III (39.8 percent) questions were analyzed (p < 0.001). The hand and lower extremity section had the highest percentage of Level III questions (50.0 percent; p = 0.005). Journal articles had a mean level of evidence of 3.9 ± 0.7. The number of articles with a low level of evidence (IV and V) (p = 0.624) and the percentage of questions supported by articles with a high level of evidence (I and II) (p = 0.406) did not vary by section. The PubMed search revealed no instances of a higher level of evidence than the recommended reading list. A significant percentage of Plastic Surgery In-Service Training Exam questions test clinical management, but most are supported with a low level of evidence. Although that is consistent with low level of evidence of plastic surgery literature, educators should recognize the potential for biases of question writers.

The Raven-II is a platform for collaborative research on advances in surgical robotics. Seven universities have begun research using this platform. The Raven-II system has two 3-DOF spherical positioning mechanisms capable of attaching interchangeable four DOF instruments. The Raven-II software is based on open standards such as Linux and ROS to maximally facilitate software development. The mechanism is robust enough for repeated experiments and animal surgery experiments, but is not engineered to sufficient safety standards for human use. Mechanisms in place for interaction among the user community and dissemination of results include an electronic forum, an online software SVN repository, and meetings and workshops at major robotics conferences.

The objective of this Chapter was to investigate the feasibility and outcome of gasless laparoscopy under regional anesthesia. A prospective evaluation of Lift-(gasless) laparoscopic procedures under regional anesthesia (Canadian Task Force classification II-1) was done at three endoscopic gynecology centers (franchise system of EndGyn(r)). Sixty-three patients with gynecological diseases comprised the cohort. All patients underwent Lift-laparoscopic surgery under regional anesthesia: 10 patients for diagnostic purposes, 17 for surgery of ovarian tumors, 14 to remove fibroids, and 22 for hysterectomies. All patients were operated without conversion to general anesthesia and without perioperative or anesthesiologic complications. Lift-laparoscopy under regional anesthesia can be recommended to all patients who desire laparoscopic intervention without general anesthesia. For elderly patients, those with cardiopulmonary risks, during pregnancy, or with contraindications for general anesthesia, Lift-laparoscopy under regional anesthesia should be the procedure of choice.

The purposes of this study were to determine the occurrence of undiagnosed "silent" obstructive sleep apnea (OSA) in dentofacial deformity (DFD) patients at initial surgical presentation and to report on the level of daytime sleepiness in DFD patients with OSA and chronic obstructive nasal breathing (CONB) after undergoing bimaxillary, chin, and intranasal surgery. A retrospective cohort study of patients with a bimaxillary DFD and CONB was implemented. Patients were divided into those with no OSA (group I) and those with OSA (group II). Group II was further subdivided into patients referred with polysomnogram (PSG)-confirmed OSA (group IIa) and those with a diagnosis of OSA only after surgical consultation, airway evaluation, and a positive PSG (group IIb). Group II patients were analyzed at a minimum of 1 year after surgery (range, 1 to 10 years) for daytime sleepiness with the Epworth Sleepiness Scale. Patients with postoperative excessive daytime sleepiness were assessed for risk factors and continued need for OSA treatment. Patients in group II were studied to determine which DFD patterns were most associated with OSA. We compared the prevalence of OSA between our study population and the general population. Two hundred sixty-two patients met the inclusion criteria. Of these, 23% (60 of 262) had PSG-confirmed OSA (group II). This rate was much higher than that found in the general population. Of the patients, 7% (19 of 262) were known to have OSA at initial surgical consultation (group IIa). An additional 16% (41 of 262) were later confirmed by PSG to have OSA (group IIb). Patients with primary mandibular deficiency and short face DFDs were most likely to have OSA (P surgery. A significant association was found between group II patients with postoperative excessive daytime sleepiness ("sleepy" or "very sleepy") and a preoperative body mass index category of overweight (P = .026). Our study found silent OSA to be frequent in the DFD population. The

Full Text Available Near-infrared spectroscopy (NIRS is used to monitor regional cerebral oxygenation (rScO2 during cardiac surgery but is less established during non-cardiac surgery. This systematic review aimed i to determine the non-cardiac surgical procedures that provoke a reduction in rScO2 and ii to evaluate whether an intraoperative reduction in rScO2 influences postoperative outcome. The PubMed and Embase database were searched from inception until April 30, 2013 and inclusion criteria were intraoperative NIRS determined rScO2 in adult patients undergoing non-cardiac surgery. The type of surgery and number of patients included were recorded. There was included 113 articles and evidence suggests that rScO2 is reduced during thoracic surgery involving single lung ventilation, major abdominal surgery, hip surgery, and laparascopic surgery with the patient placed in anti-Tredelenburg’s position. Shoulder arthroscopy in the beach chair and carotid endarterectomy with clamped internal carotid artery also cause pronounced cerebral desaturation. A >20% reduction in rScO2 coincides with indices of regional and global cerebral ischemia during carotid endarterectomy. Following thoracic surgery, major orthopedic and abdominal surgery the occurrence of postoperative cognitive dysfunction might be related to intraoperative cerebral desaturation. In conclusion, certain non-cardiac surgical procedures is associated with an increased risk for the occurrence of regional cerebral oxygenation. Evidence for an association between cerebral desaturation and postoperative outcome parameters other than cognitive dysfunction needs to be established.

To date, the genetic basis of Dubowitz syndrome (short stature, microcephaly, facial abnormalities, eczema) is unknown and vascular complications are not known to be associated with this syndrome. In microcephalic osteodysplastic primordial dwarfism type II (MOPD II; disproportionate short statue, microcephaly, facial abnormalities), however, cerebral aneurysms and other vascular abnormalities are frequent complications. MOPD II is a genetic disorder caused by mutations in the pericentrin (PCNT) gene (21q22). We report on a patient who came to our attention as a 22-year-old with subarachnoid bleeding due to a ruptured cranial aneurysm. Until then, the patient was thought and published to have Dubowitz syndrome; previously, he was treated with coronary bypass surgery for extensive coronary angiopathy. Consecutive genetic testing revealed MOPD II. After clinical stabilization, the patient was discharged to a specialized rehabilitation center where he died due to re-rupture of a cranial aneurysm. In patients with short stature-especially when clinical features are accompanied by vascular complications-MOPD II should be considered as a differential diagnosis leading to consecutive genetic testing. After detection of mutations in the PCNT gene, a full vascular status including cerebral imaging and cardiac evaluation needs to be determined in order to analyze vascular abnormalities and initiate prophylactic treatment.

Influence of Bariatric Surgery on Remission of Type 2 Diabetes

Full Text Available The plague of obesity afflicts an increasing group of people. Moreover type 2 diabetes, which is the most serious illness accompanying excessive weight, is becoming more and more common. Traditional methods of obesity treatment, such as diet and physical exercise, fail. This applies especially to people with class III obesity. The only successful way of treating obesity in their case is bariatric surgery. There are three types of bariatric surgery: restrictive procedures (reducing stomach volume, malabsorptive procedures, and mixed procedures, which combine both methods. In spite of the risk connected with the surgery and complications after it, bariatric procedures are advised to patients with class III obesity and class II with an accompanying illness which increases the probability of death. It has been proved that bariatric surgery not only eliminates obesity but also very frequently (in 90�0of cases leads to the remission of type 2 diabetes. Moreover, the remission occurs very fast – it takes place a long time before the patients reduce their weight, even within a few days after surgery. Detailed studies have shown that the remission of diabetes is caused mostly by the change of the gastro-intestinal hormones’ profile, resulting from the surgery. These hormones include GLP-1, GIP, peptide YY, ghrelin and oxyntomodulin. Additionally, the change of the amount of adipose tissue after the surgery influences the level of adipokines, i.e. the hormones of the adipose tissue, among which the most important are leptin, adiponectin and resistin. Thus, bariatric surgery not only changes the shape of the gastrointestinal tract but it also modulates the hormonal activity. Bariatric surgery is considered as therapy not only for the obese but also for diabetic patients.

Patients with Marfan syndrome are referred for cardiac surgery due to root aneurysm with or without aortic valve regurgitation. Because these patients are young and frequently present with normal-appearing aortic cusps, valve sparing is often recommended. However, due to the genetic nature of the disease, the durability of such surgery remains uncertain. Between February 2004 and June 2012, 100 patients in our department suffering from aortic aneurysm with aortic valve regurgitation underwent elective aortic valve-sparing surgery. Of them, 30 had Marfan syndrome, were significantly younger (30 +/- 13 vs. 53 +/- 16 years), and had a higher percentage of root aneurysm, compared with ascending aorta aneurysm in their non-Marfan counterparts. We evaluated the safety, durability, clinical and echocardiographic mid-term results of these patients. While no early deaths were reported in either group, there were a few major early complications in both groups. At follow-up (reaching 8 years with a mean of 34 +/- 26 months) there were no late deaths, and few major late complications in the Marfan group. Altogether, 96% and 78% of the patients were in New York Heart Association functional class I-II in the Marfan and non-Marfan groups respectively. None of the Marfan patients needed reoperation on the aortic valve. Freedom from recurrent aortic valve regurgitation > 3+ was 94% in the Marfan patients. Aortic valve-sparing surgery in Marfan symdrome patients is safe and yields good mid-term clinical outcomes.

The aim of the study was to study the feasibility, safety, and efficacy of transesophageal echocardiography-guided intraoperative left ventricular lead placement via a video-assisted thoracoscopic surgery approach in patients with failed conventional biventricular pacing. Twelve patients who could not have the left ventricular lead placed conventionally underwent epicardial left ventricular lead placement by video-assisted thoracoscopic surgery. Eight patients had previous chest surgery (66%). Operative positioning was a modified far lateral supine exposure with 30-degree bed tilt, allowing for groin and sternal access. To determine the optimal left ventricular location for lead placement, the left ventricular surface was divided arbitrarily into nine segments. These segments were transpericardially paced using a hand-held malleable pacing probe identifying the optimal site verified by transesophageal echocardiography. The pacing leads were screwed into position via a limited pericardiotomy. The video-assisted thoracoscopic surgery approach was successful in all patients. Biventricular pacing was achieved in all patients and all reported symptomatic benefit with reduction in New York Heart Association class from III to I-II (P = 0.016). Baseline ejection fraction was 23 ± 3%; within 1-year follow-up, the ejection fraction increased to 32 ± 10% (P = 0.05). The mean follow-up was 566 days. The median length of hospital stay was 7 days with chest tube removal between postoperative days 2 and 5. In patients who are nonresponders to conventional biventricular pacing, intraoperative left ventricular lead placement using anatomical and functional characteristics via a video-assisted thoracoscopic surgery approach is effective in improving heart failure symptoms. This optimized left ventricular lead placement is feasible and safe. Previous chest surgery is no longer an exclusion criterion for a video-assisted thoracoscopic surgery approach.

Current practice guidelines for antimicrobial prophylaxis in surgery recommend a cephamycin or cefazolin plus metronidazole for various abdominal surgeries. In February 2016, cephamycin drug shortages resulted in a change in The Johns Hopkins Hospital's (JHH) recommendation for peri-operative antibiotic prophylaxis in abdominal surgeries from cefotetan to cefazolin plus metronidazole. The primary objective of this study was to quantify the percentage of abdominal surgeries adherent to JHH peri-operative antibiotic prophylaxis guidelines. A sub-group analysis investigated whether prophylaxis with cefazolin plus metronidazole was associated with a lower rate of surgical site infections (SSIs) versus cefotetan. This retrospective cohort study included adult inpatients who underwent an abdominal surgery at JHH in September 2015 (Study Period I: cefotetan) or February to March 2016 (Study Period II: cefazolin plus metronidazole). Two hundred abdominal surgery cases were included in the primary analysis. A subset of 156 surgical cases were included in the sub-group analysis. The overall adherence rate to JHH guidelines was 75% in Study Period I versus 17% in Study Period II (p operative administration time (87% vs. 23%, p site infections occurred in 14% (12/83) of surgeries with cefotetan versus 8.2% (6/73) with cefazolin plus metronidazole for prophylaxis (p = 0.19). Adherence to an institution-specific peri-operative antibiotic prophylaxis guideline for abdominal surgeries was limited primarily by the longer infusion time required for pre-operative metronidazole. A higher percentage of SSIs occurred among abdominal surgeries with cefotetan versus cefazolin plus metronidazole for prophylaxis.

Brachial plexus block is often utilised for proximal arm arteriovenous access creation. However, the medial upper arm and axilla are often inadequately anaesthetised, requiring repeated, intraoperative local anaesthetic supplementation, or conversion into general anaesthesia. We hypothesised that the addition of a PECS II block would improve anaesthesia and analgesia for proximal arm arteriovenous access surgery. In this prospective, double-blinded, randomised proof-of-concept study, 36 consenting adults with end-stage renal disease aged between 21 and 90 years received either a combined supraclavicular and PECS II block (Group PECS, n = 18), or combined supraclavicular and sham block (Group SCB, n = 18) for proximal arm arteriovenous access surgery. Primary outcome was whether patients required intraoperative local anaesthetic supplementation by the surgeon. In Group PECS, 33.3% (6/18) needed local anaesthetic supplementation vs. 100% (18/18) in Group SCB. Group SCB had three times (RR 3.0, 95% CI 1.6-5.8; P PECS required lower volume of supplemental local anaesthetic compared to Group SCB (0.0 ml, IQR 0.0-6.3 ml vs. 15.0 ml, IQR 7.4-17.8 ml; P PECS II block to a supraclavicular block improves regional anaesthesia for patients with end-stage renal disease undergoing proximal arm arteriovenous access surgery. © 2018 The Acta Anaesthesiologica Scandinavica Foundation.

Background Blood eosinophil and basophil levels have recently been considered for the purpose of endotyping chronic rhinosinusitis with nasal polyps (CRSwNP). Histologically, eosinophilic-type CRSwNPs have been associated with high recurrence rates after treatment. Objective The present study was the first to compare blood eosinophil and basophil counts in eosinophilic-type CRSwNP patients before and after endoscopic sinus surgery. Methods The study concerned 79 consecutive patients with histologically confirmed eosinophilic-type CRSwNP treated with endoscopic sinus surgery. Results A significant drop in mean blood eosinophil counts and percentages occurred from before to after endoscopic sinus surgery in the cohort as a whole. Mean blood eosinophil counts and percentages were also reduced after surgery in the subcohorts of CRSwNP patients with (i) asthma, (ii) aspirin-exacerbated respiratory disease (AERD), and (iii) no allergy. Although blood eosinophil and basophil counts correlated directly before and after surgery, a statistical reduction in blood basophil counts and percentages after surgery emerged only in the subcohort of nonallergic CRSwNP patients. Conclusion Endoscopic sinus surgery can clear polyps, remove inflammatory tissue, and reduce inflammatory cytokine levels. Consistently with the biological mechanism described, endoscopic sinus surgery could coincide with a reduction in blood eosinophils in eosinophilic-type CRSwNP.

Matthews, Jemma H; Terrill, Alexander J; Barwick, Alex L; Butterworth, Paul A

2018-01-01

The extent to which podiatric surgeons follow venous thromboembolism guidelines is unknown. The aim of this study therefore, was 2-fold: (a) to determine the rate of venous thromboembolism following podiatric surgery and (b) to investigate the factors that influence the use of thromboprophylaxis. Data from 4238 patients who underwent foot and ankle surgery over 2 years were analyzed. Venous thromboembolism within the first 30 days following surgery was recorded using the Australasian College of Podiatric Surgeons surgical audit tool. Logistic regression analyses were undertaken to determine the factors that influenced thromboprophylaxis. Of the 4238 patient records, 3677 records (87%) provided complete data (age range 2-94 years; mean ± SD, 49.1 ± 19.7 years; 2693 females). A total of 7 venous thromboembolic events (0.2% rate) were reported. Operative duration and age (OR 12.63, 95% CI 9.47 to 16.84, P < 0.01), postoperative immobilization (OR 6.94, 95% CI 3.95 to 12.20, P < 0.01), and a prior history of VTE (OR 3.41, 95% CI 1.01 to 11.04, P = 0.04) were the strongest predictors of thromboprophylaxis. Podiatric foot and ankle surgery is associated with a low rate of venous thromboembolism. This may be due in part to the thromboprophylaxis regime implemented by podiatric surgeons, which closely aligns with current evidence-based guidelines. Level II: Prospective cohort study.

Richard von Volkmann (1830-1889), one of the most important surgeons of the 19(th) century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867-1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

We aimed to examine differences in MPT by age, following recovery phase II cardiac rehabilitation (CR. Methods: This longitudinal observational study assessed 50 consecutive cardiac patients who were divided into the middle-aged group (<65 years, n = 29 and older-aged group (≥65 years, n = 21. MPTs were measured at 1 and 3 months after cardiac surgery, and were compared. Results: The duration of MPT increased more significantly from month 1 to month 3 in the middle-aged group (19.2 ± 7.8 to 27.1 ± 11.6 s, p < 0.001 than in the older-aged group (12.6 ± 3.5 to 17.9 ± 6.0 s, p < 0.001. However, no statistically significant difference occurred in the % change of MPT from 1 month to 3 months after cardiac surgery between the middle-aged group and older-aged group, respectively (41.1% vs. 42.1%. In addition, there were no significant interactions of MPT in the two groups for 1 versus 3 months (F = 1.65, p = 0.20. Conclusion: Following phase II, CR improved MPT for all cardiac surgery patients.

To evaluate the efficiency of Roux-en-Y reconstruction (RY) after distal gastrectomy we compared postoperative physiological functions and disorders among patients who underwent RY, conventional Billroth I reconstruction (BI), or Billroth II reconstruction (BII). The subjects were 91 patients who had undergone distal gastrectomy for gastric cancer more than 1 month earlier. To examine the severity of gastroesophageal reflux, acid reflux and alkali reflux were assessed, and to examine the severity of duodenal reflux into the remnant stomach, biliary scintigraphy was performed. The degree of inflammation in the esophagus and remnant stomach was examined by endoscopy. Questionnaires on postoperative complaints were sent out to the patients to determine how serious their reflux symptoms were. Both acid and alkali reflux were mild in the RY group. Biliary reflux into the remnant stomach, as assessed by biliary scintigraphy, was significantly less severe in the RY group than in the BI and BII groups. Endoscopy showed that inflammation of the lower esophagus and remnant stomach was much less severe in the RY group than in the BI and BII groups. According to the questionnaire survey, none of the patients in the RY group reported any reflux symptoms. In this series, RY was found to be a superior reconstruction method after distal gastrectomy since it was rarely accompanied by the reflux of duodenal juice into the remnant stomach or gastric reflux into the lower esophagus.

Pectoral plane blocks (PECs) are increasingly used in analgesia for patients undergoing breast surgery, and were recently found to be at least equivalent to single-shot paravertebral anaesthesia. However, there are no data comparing PECs with the popular practice of continuous local anaesthetic wound infusion (LA infusion) analgesia for breast surgery. Therefore, we compared the efficacy and safety of PECs blocks with LA infusion, or a combination of both in patients undergoing non-ambulatory breast-cancer surgery. This single-centre, prospective, randomised, double-blind trial analysed 45 women to receive either PECs blocks [levobupivacaine 0.25%, 10 ml PECs I and levobupivacaine 0.25%, 20 ml PECs II (PECs group); LA infusion catheter (levobupivacaine 0.1% at 10 ml h -1 for 24 h (LA infusion group); or both (PECs and LA infusion)]. The primary outcome measure was area under the curve of the pain verbal rating score whilst moving vs time (AUC) over 24 h. Secondary outcomes included total opioid consumption at 24 h. AUC moving was mean (SD) 71 (34) mm h -1 vs 58 (41) vs 23 (20) in PECs, LA infusion, and both, respectively; P=0.002. AUC at rest was also significantly lower in patients receiving both. The total 24 h opioid consumption [median (25-75%)] was 14 mg (9-26) vs 11 (8-24) vs 9 (5-11); P=0.4. No adverse events were observed. The combination of both pre-incisional PECs blocks and postoperative LA infusion provides better analgesia over 24 h than either technique alone after non-ambulatory breast-cancer surgery.

2010-07-01

Full Text Available Abstract Background Postoperative adhesions occur when fibrous strands of internal scar tissue bind anatomical structures to one another. The most common cause of intra-abdominal adhesions is previous intra-abdominal surgical intervention. Up to 74% of intestinal obstructions are caused by post surgical adhesions. Although a variety of methods and agents have been investigated to prevent post surgical adhesions, the problem of peritoneal adhesions remains largely unsolved. Materials serving as an adhesion barrier are much needed. Methods/Design This is a prospective, randomised, controlled, patient blinded and observer blinded, single centre phase I-II trial, which evaluates the safety of A-Part® Gel as an adhesion prophylaxis after major abdominal wall surgery, in comparison to an untreated control group. 60 patients undergoing an elective median laparotomy without prior abdominal surgery are randomly allocated into two groups of a 1:1- ratio. Safety parameter and primary endpoint of the study is the occurrence of wound healing impairment or peritonitis within 28 (+10 days after surgery. The frequency of anastomotic leakage within 28 days after operation, occurrence of adverse and serious adverse events during hospital stay up to 3 months and the rate of adhesions along the scar within 3 months are defined as secondary endpoints. After hospital discharge the investigator will examine the enrolled patients at 28 (+10 days and 3 months (±14 days after surgery. Discussion This trial aims to assess, whether the intra-peritoneal application of A-Part® Gel is safe and efficacious in the prevention of post-surgical adhesions after median laparotomy, in comparison to untreated controls.

In addition, this study attempts to identify factors associated with receiving primary RT. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB, 2004-2013). Subjects and Methods Reviewing the NCDB from 2004 to 2013, patients with early stage I to II OCSCC were identified. Kaplan-Meier estimates of survival, Cox regression analysis, and propensity score matching were used to examine differences in OS between primary surgery and primary RT. Multivariable logistic regression analysis was performed to identify factors associated with primary RT. Results Of the 20,779 patients included in the study, 95.4% (19,823 patients) underwent primary surgery and 4.6% (956 patients) underwent primary RT. After adjusting for covariates, primary RT was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 1.97; 99% confidence interval [CI], 1.74-2.22). On multivariable analysis, factors associated with primary RT included age ≥70 years, black race, Medicaid or Medicare insurance, no insurance, oral cavity subsite other than tongue, clinical stage II disease, low-volume treatment facilities, and earlier treatment year. Conclusion Primary RT for early stage OCSCC is associated with increased mortality. Approximately 5% of patients receive primary RT; however, this percentage is decreasing. Patients at highest risk for receiving primary RT include those who are elderly, black, with public insurance, and treated at low-volume facilities.

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 investigate capsular outcomes 12 months after pediatric cataract surgery without intraocular lens implantation via qualitative classification and quantitative measurement.This study is a cross-sectional study that was approved by the institutional review board of Zhongshan Ophthalmic Center of Sun Yat-sen University in Guangzhou, China.Digital coaxial retro-illumination photographs of 329 aphakic pediatric eyes were obtained 12 months after pediatric cataract surgery without intraocular lens implantation. Capsule digital coaxial retro-illumination photographs were divided as follows: anterior capsule opening area (ACOA), posterior capsule opening area (PCOA), and posterior capsule opening opacity (PCOO). Capsular outcomes were qualitatively classified into 3 types based on the PCOO: Type I-capsule with mild opacification but no invasion into the capsule opening; Type II-capsule with moderate opacification accompanied by contraction of the ACOA and invasion to the occluding part of the PCOA; and Type III-capsule with severe opacification accompanied by total occlusion of the PCOA. Software was developed to quantitatively measure the ACOA, PCOA, and PCOO using standardized DCRPs. The relationships between the accurate intraoperative anterior and posterior capsulorhexis sizes and the qualitative capsular types were statistically analyzed.The DCRPs of 315 aphakic eyes (95.8%) of 191 children were included. Capsular outcomes were classified into 3 types: Type I-120 eyes (38.1%); Type II-157 eyes (49.8%); Type III-38 eyes (12.1%). The scores of the capsular outcomes were negatively correlated with intraoperative anterior capsulorhexis size (R = -0.572, P PCOA increased in size from Type I to Type II, and the PCOO increased from Type II to Type III (all P < 0.05).Capsular outcomes after pediatric cataract surgery can be qualitatively classified and quantitatively measured by acquisition, division, definition, and user

Full Text Available Surgery in patients with neuromuscular scoliosis is associated with a higher rate of complications. It is still controversially discussed whether the patients truly benefit from deformity correction. The purpose of this study is to investigate if the quality of life has been improved and if the patients and their caregivers are satisfied with the results of surgery. This is a retrospective clinical outcome study of 46 patients with neuromuscular scoliosis which were treated with primary stable posterior pedicle screw instrumentation and correction. To achieve fusion only autologous bone was used. Follow up was minimum 2 years and maximum 5 years with an average of 36 months. The patients and/or their caregivers received a questionnaire based on the PEDI (pediatric disability inventory and the GMFS (gross motor function score. The patients (and their caregivers were also asked if the quality of life has improved after surgery. Only 32 of 46 patients answered the questionnaire. The answers showed a high approval-rate regarding the patients satisfaction with the surgery and the improvement of quality of life. The questionnaire could be answered from 1 (I do not agree to 4 (I completely agree. The average agreement to the following statements was: i the quality of life has improved: 3.35; ii I am satisfied with surgery: 3.95; iii the operation has fulfilled my expectations: 3.76. The average age at surgery was 12.7 years. The mean pre-operative cobb-angle of the main curve was 83.1° with a correction post-operatively to a mean of 36.9° and 42.6° at final follow-up. That is an average correction of 56.9%. Although spinal fusion in neuromuscular scoliosis is associated with a higher rate of complications our results show that the patients and their caregivers are satisfied with the operation and the quality of life has improved after surgery.

Many insurance companies have considerable prebariatric surgery requirements despite a lack of evidence for improved clinical outcomes. The hypothesis of this study is that insurance-specific requirements will be associated with a decreased progression to surgery and increased delay in time to surgery. Retrospective data collection was performed for patients undergoing bariatric surgery evaluation from 2010-2015. Patients who underwent surgery (SGY; n = 827; mean body mass index [BMI] 49.1) were compared with those who did not (no-SGY; n = 648; mean BMI: 49.4). Univariate and multivariate analysis were performed to identify specific co-morbidity and insurance specific predictors of surgical dropout and time to surgery. A total of 1475 patients using 12 major insurance payors were included. Univariate analysis found insurance requirements associated with surgical drop out included longer median diet duration (no-SGY = 6 mo; SGY = 3 mo; Psurgery dropout. Additionally, surgical patients had an average interval between initial visit and surgery of 5.8±4.6 months with significant weight gain (2.1 kg, Psurgery insurance requirements were associated with lack of patient progression to surgery in this study. In addition, delays in surgery were associated with preoperative weight gain. Although prospective and multicenter studies are needed, these findings have major policy implications suggesting insurance requirements may need to be reconsidered to improve medical care.

The National Institute of Clinical Excellence states that bariatric surgery may be considered for adolescents with severe obesity in 'exceptional circumstances'. However, it is not clear what is deemed to be exceptional, and there is a lack of long-term outcomes data or research, which would inform patient selection. This is an in-depth qualitative study involving five adolescents who had previously undergone bariatric surgery (between 1 and 3 years postoperatively) and four who were being assessed for the treatment. All patients were from one tertiary NHS weight management service offering bariatric surgery to adolescents. Participants were interviewed to explore how young people decide whether bariatric surgery is an appropriate intervention for them. Of the nine adolescents recruited, four were male and five female, aged between 17 and 20 years at the time of interview. Participants who had already undergone surgery did so between the ages of 16 and 18. The data were analysed using interpretative phenomenological analysis, and key themes were identified, such as (i) wanting a different future, (ii) experiences of uncertainty, (iii) managing the dilemmas and (iv) surgery as the last resort. The findings suggest that young people are prepared to accept a surgical solution for obesity despite numerous dilemmas. Young people choose this intervention as a way of 'normalizing' when they perceive there is nothing better available. It is argued that these findings may have implications for the counselling of young people living with overweight and obesity and for government policy. © 2018 World Obesity Federation.

The American College of Surgeons has developed a verification program for children's surgery centers. Highly specialized hospitals may be verified as Level I, while those with fewer dedicated resources as Level II or Level III, respectively. We hypothesized that more specialized children's centers would utilize more resources. We performed a retrospective study of the Maryland Health Services Cost Review Commission (HSCRC) database from 2009 to 2013. We assessed total charge, length of stay (LOS), and charge per day for all inpatients with an emergency pediatric surgery diagnosis, controlling for severity of illness (SOI). Using published resources, we assigned theoretical level designations to each hospital. Two hospitals would qualify as Level 1 hospitals, with 4593 total emergency pediatric surgery admissions (38.5%) over the five-year study period. Charges were significantly higher for children treated at Level I hospitals (all P<0.0001). Across all SOI, children at Level I hospitals had significantly longer LOS (all P<0.0001). Hospitals defined as Level II and Level III provided the majority of care and were able to do so with shorter hospitalizations and lower charges, regardless of SOI. As care shifts towards specialized centers, this charge differential may have significant impact on future health care costs. Level III Cost Effectiveness Study. Copyright © 2018 Elsevier Inc.

To compare toric intraocular lens (IOL) alignment assisted by image-guided surgery or manual marking methods and its impact on visual quality. This prospective comparative study enrolled 80 eyes with cataract and astigmatism ≥1.5 D to undergo phacoemulsification with toric IOL alignment by manual marking method using bubble marker (group I, n=40) or Callisto eye and Z align (group II, n=40). Postoperatively, accuracy of alignment and visual quality was assessed with a ray tracing aberrometer. Primary outcome measure was deviation from the target axis of implantation. Secondary outcome measures were visual quality and acuity. Follow-up was performed on postoperative days (PODs) 1 and 30. Deviation from the target axis of implantation was significantly less in group II on PODs 1 and 30 (group I: 5.5°±3.3°, group II: 3.6°±2.6°; p =0.005). Postoperative refractive cylinder was -0.89±0.35 D in group I and -0.64±0.36 D in group II ( p =0.003). Visual acuity was comparable between both the groups. Visual quality measured in terms of Strehl ratio ( p image-guided surgery group. Significant negative correlation was observed between deviation from target axis and visual quality parameters (Strehl ratio and MTF) ( p Image-guided surgery allows precise alignment of toric IOL without need for reference marking. It is associated with superior visual quality which correlates with the precision of IOL alignment.

To evaluate the effect of introducing a robotic program on cost and patient outcome. This was a prospective evaluation of clinical outcome and cost after introducing a robotics program for the treatment of endometrial cancer and a retrospective comparison to the entire historical cohort. Consecutive patients with endometrial cancer who underwent robotic surgery (n=143) were compared with all consecutive patients who underwent surgery (n=160) before robotics. The rate of minimally invasive surgery increased from 17% performed by laparoscopy to 98% performed by robotics in 2 years. The patient characteristics were comparable in both eras, except for a higher body mass index in the robotics era (median 29.8 compared with 27.6; Probotics had longer operating times (233 compared with 206 minutes), but fewer adverse events (13% compared with 42%; Probotics compared with the historical group (Can$7,644 compared with Can$10,368 [Canadian dollars]; Psurgery, the short-term recurrence rate appeared lower in the robotics group compared with the historic cohort (11 recurrences compared with 19 recurrences; Probotics for endometrial cancer surgery increased the proportion of patients benefitting from minimally invasive surgery, improved short-term outcomes, and resulted in lower hospital costs.

A 12-year-old mixed-breed male dog was referred to the Clinica Medica Veterinaria of Bologna University for recurrent episodes of seizures due to hypoglycemia with abnormally low plasma insulin levels (18 pmol/l). Resection of a large leiomyoma (780 g) of the gastric wall resulted in a permanent resolution of the hypoglycemic episodes. Insulin-like growth factors I and II (IGF-I and -II) were measured by RIA in serum before and after surgery and in tumor tissue. Results were compared to the serum concentration of 54 normal and to the tissue concentration observed in eight non-hypoglycemic dog gastric wall extracts. Before surgery, circulating immunoreactive IGF-I was 0.92 nmol/l, which is significantly lower than the control values (16.92 +/- 8.44 nmol/l, range 3.53-35.03), while IGF-II was 152 nmol/l, which is significantly higher than the control values (42.21 +/- 3.75, range 31.99-50.74). After surgery, IGF-I increased to 6.80 nmol/l while IGF-II decreased to 45.52 nmol/l. Tumor tissue IGF-II concentration was higher than normal (5.66 nmol/kg tissue as compared to a range in normal gastric wall tissue of 1.14-3.72 nmol/kg), while IGF-I was 0.08 nmol/kg tissue, which is close to the lowest normal value (range in controls, 0.08-1.18 nmol/kg). Partial characterization of IGF-II immunoreactivity extracted from tissue evidenced a molecular weight similar to that of mature IGF-II, thus excluding that peptide released by the tumor is a precursor molecule.(ABSTRACT TRUNCATED AT 250 WORDS)

Strabismus surgery is a frequently performed pediatric ocular procedure. A frequently occurring major problem in patients receiving this treatment involves the oculocardiac reflex. This reflex is associated with an increased incidence of postoperative nausea, vomiting, and pain. The aim of this study was to investigate the effects of a sub-Tenon's block on the oculocardiac reflex, pain, and postoperative nausea and vomiting. Forty patients aged 5-16 years with American Society of Anesthesiologists status I-II undergoing elective strabismus surgery were included in this study. Patients included were randomly assigned into two groups by using a sealed envelope method. In group 1 (n=20), patients did not receive sub-Tenon's anesthesia. In group 2 (n=20), following intubation, sub-Tenon's anesthesia was performed with the eye undergoing surgery. Atropine use, pain scores, oculocardiac reflex, and postoperative nausea and vomiting incidences were compared between groups. There were no significant differences between groups with regard to oculocardiac reflex and atropine use (p>0.05). Pain scores 30min post-surgery were significantly lower in group 2 than in group 1 (p<0.05). Additional analgesic needed during the postoperative period was significantly lower in group 2 compared to group 1 (p<0.05). In conclusion, we think that a sub-Tenon's block, combined with general anesthesia, is not effective and reliable in decreasing oculocardiac reflex and postoperative nausea and vomiting. However, this method is safe for reducing postoperative pain and decreasing additional analgesia required in pediatric strabismus surgery. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

To classify the cerebral cavernous malformations and to investigate the natural history of cavernous malformations according to the classification, 41 patients with 61 cavernous malformations (40 cavernous malformations from 22 patients treated with gamma knife surgery) were regularly followed up using MR imaging for a mean period of 25.5 months in treated cavernous malformations and 20.7 months in untreated cavernous malformations, respectively. Cavernous malformations were classified into four types. Follow-up MR images were analyzed to evaluate changes in size, signal intensity, rebleeding, and perilesional adverse reaction of irradiation. A total of 61 cavernous malformations including 17 in type I, 23 in type II, 10 in type III, and 11 in type IV showed usual degradation of blood product in 22 cavernous malformations, no change in shape and signal intensity in 31 cavernous malformations, and eight cavernous malformations with rebleedings in the serial MR images. In these eight cavernous malformations with rebleedings, six occurred in type II and two in type III, but none in type I or IV. Rebleedings were more frequent in type II than in other types. Adverse reaction of irradiation was observed in five of 22 patients treated with gamma knife surgery. Although most cerebral cavernous malformations showed evolution of hemorrhage or no change in size or shape on follow-up MR images, cerebral cavernous malformations represented as mixture of subacute and chronic hemorrhage with hemosiderin rim (type II) have a higher frequency to rebleed than other types of cerebral cavernous malformations. Cerebral cavernous malformations represented as hemosiderin deposition without central core (type IV) have a lower tendency to rebleed than other types and do not need any treatment. Most of the adverse reaction of irradiation after gamma knife surgery around cavernous malformations are transient findings and are considered to be perilesional edema. (K.H)

Who is at increased risk for acute kidney injury following noncardiac surgery?

Murray, Patrick

2009-01-01

Abelha and colleagues evaluated the incidence and determinants of postoperative acute kidney injury (AKI) after major noncardiac surgery in patients with previously normal renal function. In this retrospective study of 1,166 patients with no previous renal insufficiency, who were admitted to a postsurgical intensive care unit (ICU) over a 2-year period, the incidence of AKI was 7.5%. Multivariate analysis identified American Society of Anesthesiologists physical status, Revised Cardiac Risk Index, high-risk surgery and congestive heart disease as preoperative AKI risk factors. AKI was an independent risk factor for hospital mortality (odds ratio = 3.12, 95% confidence interval = 1.41 to 6.93; P = 0.005), and was associated with higher severity of illness scores (Simplified Acute Physiology Score II and Acute Physiology and Chronic Health Evaluation II), longer ICU length of stay, higher ICU mortality, increased hospital mortality and higher mortality at 6-month follow up. Although the study design excluded 121 patients with significant preoperative renal insufficiency by design, the relatively crude serum creatinine cut-offs used certainly permitted inclusion of numerous patients with preoperative renal impairment. Accordingly, the study design failed to quantify the impact of preoperative renal impairment on risk and outcomes of perioperative AKI in noncardiac surgery, and this should be a goal of such studies in the future. Nonetheless, the study is an important addition to the literature in an under-studied population of patients at high risk for AKI.

2015-01-01

Full Text Available Background: Sympathetic ophthalmitis (SO has been reported following vitrectomy; however, there is a lack of data on the role of antecedent penetrating ocular trauma impacting the disease manifestation in eyes developing SO following vitrectomy. Aim: To report differences in the presentation and outcomes of SO in eyes with or without a history of antecedent penetrating trauma; SO being diagnosed after vitreoretinal (VR surgery. Design: Comparative case series. Methods: Seventeen consecutive patients presenting with SO following VR surgery, diagnosed between 1995 and 2011 were included. Eyes with and without prior penetrating injury were included in Group I (n = 7 and Group II (n = 10, respectively. All Group I patients had received systemic steroids prior to presentation. Demographic and clinical parameters were evaluated. Results: Differences were observed between Group I and Group II mainly with regards to time interval between VR surgery and diagnosis of SO (1.5 months vs. 8 months, P = 0.10, presence of neurosensory detachments (100% vs. 30%, P = 0.01, and the inciting eye vision at presentation (nil light perception in 28.5% vs. 80%, P = 0.049. Other differences observed though not statistically significant were optic disc and retinal vessel involvement (42% vs. 70%, P = 0.28, Dalen-Fuchs nodules (localized vs. diffuse and leaks on fundus fluorescein angiography (pin-head vs. pin-point leak. Conclusion: SO in patients with antecedent penetrating ocular trauma present early with the central serous chorioretinopathy-like picture. Prior use of systemic steroids might have a bearing on the differences in presentation and the visual acuities between the two groups.

Type II Intertrochanteric Fractures: Proximal Femoral Nailing (PFN Versus Dynamic Hip Screw(DHS

Cyril Jonnes

2016-01-01

Full Text Available Background: Intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. Dynamic Hip Screw (DHS is still considered the gold standard for treating intertrochanteric fractures by many. Not many studies compare the DHS with Proximal femoral nail (PFN, in Type II intertrochanteric fractures (Boyd and Griffin classification. This study was done to compare the functional and radiological outcome of PFN with DHS in treatment of Type II intertrochanteric fractures.   Methods: From October 2012 to March 2015, a prospective comparative study was done where 30 alternative cases of type II intertrochanteric fractures of hip were operated using PFN or DHS. Intraoperative complications were noted. Functional outcome was assessed using Harris Hip Score and radiological findings were compared at 3, 6, and 12 months postoperatively. Results: The average age of the patients was 60 years. In our series we found that patients with DHS had increased intraoperative blood loss (159ml, longer duration of surgery (105min, and required longer time for mobilization while patients who underwent PFN had lower intraoperative blood loss (73ml, shorter duration of surgery (91min, and allowed early mobilization. The average limb shortening in DHS group was 9.33 mm as compared with PFN group which was only 4.72 mm. The patients treated with PFN started early ambulation as they had better Harris Hip Score in the early post-op period. At the end of 12th month, there was not much difference in the functional outcome between the two groups. Conclusion: PFN is better than DHS in type II inter-trochanteric fractures in terms of decreased blood loss, reduced duration of surgery, early weight bearing and mobilization, reduced hospital stay, decreased risk of infection and decreased complications.

Advances in early management of congenital heart disease (CHD) have led to an exponential growth in adults with CHD (ACHD). Many of these patients require cardiac surgery. This study sought to examine outcome and its predictors for ACHD cardiac surgery. This is an observational cohort study of prospectively collected data on 1090 consecutive adult patients with CHD, undergoing 1130 cardiac operations for CHD at the Royal Brompton Hospital between 2002 and 2011. Early mortality was the primary outcome measure. Midterm to longer-term survival, cumulative incidence of reoperation, other interventions and/or new-onset arrhythmia were secondary outcome measures. Predictors of early/total mortality were identified. Age at surgery was 35±15 years, 53% male, 52.3% were in New York Heart Association (NYHA) class I, 37.2% in class II and 10.4% in class III/IV. Early mortality was 1.77% with independent predictors NYHA class ≥ III, tricuspid annular plane systolic excursion (TAPSE) <15 mm and female gender. Over a mean follow-up of 2.8±2.6 years, 46 patients died. Baseline predictors of total mortality were NYHA class ≥ III, TAPSE <15 mm and non-elective surgery. The number of sternotomies was not independently associated with neither early nor total mortality. At 10 years, probability of survival was 94%. NYHA class among survivors was significantly improved, compared with baseline. Contemporary cardiac surgery for ACHD performed at a single, tertiary reference centre with a multidisciplinary approach is associated with low mortality and improved functional status. Also, our findings emphasise the point that surgery should not be delayed because of reluctance to reoperate only. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Full Text Available The surgery-first approach in orthognathic surgery has recently created a broader interest in completely eliminating time-consuming preoperative orthodontic treatment. Available evidence on the surgery-first approach should be appraised to support its use in orthognathic surgery. A MEDLINE search using the keywords "surgery first" and "orthognathic surgery" was conducted to select studies using the surgery-first approach. We also manually searched the reference list of the selected keywords to include articles not selected by the MEDLINE search. The search identified 18 articles related to the surgery-first approach. There was no randomized controlled clinical trial. Four papers were excluded as the content was only personal opinion or basic scientific research. Three studies were retrospective cohort studies in nature. The other 11 studies were case reports. For skeletal Class III surgical correction, the final long-term outcomes for maxillofacial and dental relationship were not significantly different between the surgery-first approach and the orthodontics-first approach in transverse (e.g., intercanine or intermolar width dimension, vertical (e.g., anterior open bite, lower anterior facial height dimension, and sagittal (e.g., anterior-posterior position of pogonion and lower incisors dimension. Total treatment duration was substantially shorter in cases of surgery-first approach use. In conclusion, most published studies related to the surgery-first approach were mainly on orthognathic correction of skeletal Class III malocclusion. Both the surgery-first approach and orthodontics-first approach had similar long-term outcomes in dentofacial relationship. However, the surgery-first approach had shorter treatment time.

Full Text Available Orthognathic surgery in conjunction with fixed orthodontics is a common indication for interdisciplinary management of severe skeletal Class III malocclusion. A thorough analysis of pretreatment investigations and development of a surgical visual treatment objective is essential to plan the type of surgical technique required. Bimaxillary orthognathic surgery is the most common type of surgical procedure for severe skeletal discrepancies. The present case report is a combined ortho-surgical team management of a skeletally Class III patient. The severity of the case required bilateral upper first premolar extraction for dentoalveolar decompensation and simultaneous “Two-jaw surgery” with maxillary advancement of 4 mm and mandibular setback of 7 mm. Postsurgery, a pleasing good facial profile was achieved with Class II molar relation and positive overjet.

Frozen shoulder is a potential complication after shoulder surgery. It is a clinical condition that is often associated with marked disability and can have a profound effect on the patient's quality of life. The incidence, etiology, pathology and prognostic factors of postoperative frozen shoulder after shoulder surgery are not known. The purpose of this explorative study was to determine the incidence of postoperative frozen shoulder after various operative shoulder procedures. A second aim was to identify prognostic factors for postoperative frozen shoulder after shoulder surgery. 505 consecutive patients undergoing elective shoulder surgery were included in this prospective cohort study. Follow-up was 6 months after surgery. A prediction model was developed to identify prognostic factors for postoperative frozen shoulder after shoulder surgery using the TRIPOD guidelines. We nominated five potential predictors: gender, diabetes mellitus, type of physiotherapy, arthroscopic surgery and DASH score. Frozen shoulder was identified in 11% of the patients after shoulder surgery and was more common in females (15%) than in males (8%). Frozen shoulder was encountered after all types of operative procedures. A prediction model based on four variables (diabetes mellitus, specialized shoulder physiotherapy, arthroscopic surgery and DASH score) discriminated reasonably well with an AUC of 0.712. Postoperative frozen shoulder is a serious complication after shoulder surgery, with an incidence of 11%. Four prognostic factors were identified for postoperative frozen shoulder: diabetes mellitus, arthroscopic surgery, specialized shoulder physiotherapy and DASH score. The combination of these four variables provided a prediction rule for postoperative frozen shoulder with reasonable fit. Level II, prospective cohort study.

The aim of this longitudinal study was to assess and compare the oral health-related quality of life (OHRQoL) of patients with class II and III deformities during and after orthodontic-surgical treatment. Thirty class III and 28 class II patients were evaluated at baseline (T0), just prior to surgery (T1), at 6 months after surgery (T2), and at 12 months after debonding (T3). OHRQoL was assessed using the Oral Health Impact Profile (OHIP-14). Friedman two-way analysis of variance and the Wilcoxon signed-rank test were performed to compare the relative changes in OHRQoL during treatment. Significant changes in the overall OHIP-14 scores were observed during and after orthodontic-surgical treatment in both groups. During the pre-surgical stage, psychological discomfort and psychological disability decreased in class III patients, and class II patients experienced a significant deterioration in psychological discomfort during the same period. Six months after surgery, patients in both groups showed improvements in psychological discomfort, social disability, and handicap. Physical disability and functional limitation showed further improvement at 12 months after debonding in class II patients. This study reaffirms that orthodontic-surgical treatment has a significant effect on the OHRQoL of class III and class II patients.

Retinal detachment is a rare complication in patients with retinitis pigmentosa. A case is reported of tractional retinal detachment in a patient with retinitis pigmentosa and sensorineural hearing loss, which was diagnosed as Usher syndrome type II. Because of the poor visual prognosis, the patient refused surgery in that eye. Tractional retinal detachment should be added to the differential diagnoses of visual loss in patients with retinitis pigmentosa.

Timing of surgery in the management of infective endocarditis is controversial, and there is still no definite conclusion on how early the surgery should be performed. This study focuses on the outcomes of surgery during the active period of infective endocarditis in consideration of the duration after diagnosis. One hundred and thirty-four patients with active native valve infective endocarditis who underwent surgery from January 2006 to December 2013 were reviewed retrospectively. They were divided in 2 groups based on timing of surgery: early group (first week after diagnosis, n = 37) and delayed group (2 to 6 weeks after diagnosis, n = 97). Compared to the delayed group, the early group had significantly more patients in New York Heart Association class IV (81% vs. 43.3%), more mechanically ventilated (54.1% vs. 18.6%), more on inotropic support (62.2% vs. 38.1%), and hence a worse EuroSCORE II (14.8% vs. 8.8%). Operative mortality was comparable (5.4% vs. 10.3%) and 7-year survival was similar (77.4% vs. 74.6%). On multivariable regression analysis, delayed surgery did not impact on short- and long-term outcomes. Preoperative cardiac arrest and infection with Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, or Kingella were risk factors for higher operative mortality. Predictors of poor 7-year survival were diabetes mellitus and acute renal failure. Delayed surgery is not associated with worse outcomes. Both early and delayed approaches are safe and provide acceptable results. Timing of surgery should be tailored to each patient's clinical status, not based on duration of endocarditis alone. © The Author(s) 2016.

Efforts to standardize hand surgery training during plastic surgery residency remain challenging. We analyze the variability of operative hand experience at U.S. plastic surgery residency programs. Operative case logs of chief residents in accredited U.S. plastic surgery residency programs were analyzed (2011-2015). Trends in fold differences of hand surgery case volume between the 10th and 90th percentiles of residents were assessed graphically. Percentile data were used to calculate the number of residents achieving case minimums in hand surgery for 2015. Case logs from 818 plastic surgery residents were analyzed of which a minority were from integrated (35.7%) versus independent/combined (64.3%) residents. Trend analysis of fold differences in case volume demonstrated decreasing variability among procedure categories over time. By 2015, fold differences for hand reconstruction, tendon cases, nerve cases, arthroplasty/arthrodesis, amputation, arterial repair, Dupuytren release, and neoplasm cases were below 10-fold. Congenital deformity cases among independent/combined residents was the sole category that exceeded 10-fold by 2015. Percentile data suggested that approximately 10% of independent/combined residents did not meet case minimums for arterial repair and congenital deformity in 2015. Variable operative experience during plastic surgery residency may limit adequate exposure to hand surgery for certain residents. Future studies should establish empiric case minimums for plastic surgery residents to ensure hand surgery competency upon graduation. Copyright © 2017 Association of Program Directors in Surgery.

To assess diagnostic performance of routine CT for detecting anastomotic leak after gastric surgery, and analyse the relationship between recovery period and CT findings. We included 179 patients who underwent immediate CT and fluoroscopy after gastric surgery. Two reviewers retrospectively rated the possibility of leak on CT using a five-point scale focused on predefined CT findings. They also evaluated CT findings. Patients were categorised as: Group I, leak on fluoroscopy; Group II, possible leak on CT but negative on fluoroscopy; Group III, no leak. We analysed the relationship between recovery period and group. Area under the curve for detecting leak on CT was 0.886 in R1 and 0.668 in R2 with moderate agreement (k = 0.482). Statistically common CT findings for leak included discontinuity, large amount of air-fluid and wall thickening at anastomosis site (p < 0.05). Discontinuity at anastomosis site and a large air-fluid collection were independently associated with leak (p < 0.05). The recovery period including hospitalisation and postoperative fasting period was longer in Group I than Group II or III (p < 0.05). Group II showed a longer recovery period than Group III (p < 0.05). Postoperative routine CT was useful for predicting anastomotic leak using specific findings, and for predicting length of recovery period. (orig.)

The number of obese young people continues to rise, with a corresponding increase in extreme obesity and paediatric-adolescent bariatric surgery. We aimed to (i) systematically review the literature on bariatric surgery in children and adolescents; (ii) meta-analyse change in body mass index (BMI) 1-year post-surgery and (iii) report complications, co-morbidity resolution and health-related quality of life (HRQoL). A systematic literature search (1955-2013) was performed to examine adjustable gastric band, sleeve gastrectomy, Roux-en-Y gastric bypass or biliopancreatic diversions operations among obese children and adolescents. Change in BMI a year after surgery was meta-analysed using a random effects model. In total, 637 patients from 23 studies were included in the meta-analysis. There were significant decreases in BMI at 1 year (average weighted mean BMI difference: -13.5 kg m(-2) ; 95% confidence interval [CI] -14.1 to -11.9). Complications were inconsistently reported. There was some evidence of co-morbidity resolution and improvements in HRQol post-surgery. Bariatric surgery leads to significant short-term weight loss in obese children and adolescents. However, the risks of complications are not well defined in the literature. Long-term, prospectively designed studies, with clear reporting of complications and co-morbidity resolution, alongside measures of HRQol, are needed to firmly establish the harms and benefits of bariatric surgery in children and adolescents. © 2013 The Authors. obesity reviews © 2013 International Association for the Study of Obesity.

The treatment of congenital scoliosis associated with split cord malformation (SCM) raises the issue of how to best manage such patients to avoid neurological deficit while achieving a satisfactory correction. This prospective clinical study was performed at our center from March 2000 through June 2013. We enrolled a total of 214 patients (61 male and 153 female) with congenital scoliosis associated with SCM who were undergoing spinal correction surgery. The mean age at surgery was 14.1 years. The inclusion criteria were congenital scoliosis with confirmed SCM; status as neurologically intact or stable over the preceding 2 years; and no neurological deterioration as evidenced on traction, side-bending, or fulcrum-bending radiographs. Patients with unstable neurological status or for whom vertebral column resection surgery was planned were excluded. All patients underwent scoliosis surgery without prophylactic detethering. On the basis of the Pang classification, 73 patients were in the type-I SCM group, and 141 were in the type-II SCM group. The groups did not differ significantly with respect to preoperative characteristics, operative time, blood loss, or number of levels fused. The mean follow-up was 37 months (range, 24 to 108 months). The rate of scoliosis correction was lower in the type-I group than in the type-II group (p patients experienced transient neurological complications, with no significant difference between the groups (p = 0.415). No patient experienced permanent neurological deficit during surgery or follow-up. Patients with congenital scoliosis associated with SCM, regardless of type, can safely and effectively undergo spinal deformity correction and achieve spinal balance without neurological intervention. For such patients with intact or stable neurological status, prophylactic detethering prior to scoliosis surgery may not be necessary. Therapeutic Level II.

According to the Guidelines for breast-conserving therapy of the Japanese Breast Cancer Society, the surgical margin is ''negative'' when the minimum distance between the tumor edge and the margin of the resected specimen is more than 5 mm. The value of boost radiation for early breast cancer with a 5-mm negative margin remains unclear. A total of 137 patients with stage I-II breast cancer underwent breast-conserving surgery between July 1987 and August 2002. All of the patients had negative margins according to the Japanese guidelines. Their median age was 50 years and the median follow-up period was 62 months. The entire ipsilateral breast was irradiated to a total dose of 50 Gy (25 fractions). Then an additional 10 Gy (5 fractions) was given to 79 patients, using 6- to 12-MeV electrons (boost group), while 58 patients (no-boost group) received no further radiation. Factors influencing local recurrence were evaluated by univariate and multivariate analyses. For the entire population, the 5-year overall survival, cause-specific survival, disease-free survival, and local recurrence rates were 96.0%, 96.8%, 94.2%, and 1.67%, respectively. Boost radiation reduced local recurrence, but the improvement was not significant (P=0.070). Univariate and multivariate analyses failed to detect any factors that were significantly associated with local control. There were no severe complications in either group and there were no differences between the groups in the cosmetic outcome. Boost radiation can be performed for stage I-II breast cancer with negative margins (Japanese guidelines), and showed a tendency to decrease local recurrence. A large randomized controlled study is necessary to establish final conclusions. (author)

Total knee replacement (TKR) surgery is one of the most frequent and the most extensive procedures in orthopedic surgery, accompanied with some serious complications. Perioperative blood loss is one of the most serious losses, so it is vital to recognize and treat such losses properly. Autologous blood transfusion is the only true alternative for the allogeneic blood. The aim of this study was to to examine if autologous blood transfusion reduces usage of allogenic blood in total knee replacement surgery, as well as to examine possible effect of autologous blood transfusion on postoperative complications, recovery and hospital stay of patients after total knee replacement surgery. During the controlled, prospective, randomised study we compared two groups of patients (n = 112) with total prosthesis implanted in their knee. The group I consisted of the patients who received the transfusion of other people's (allogeneic) blood (n = 57) and the group II of the patients whose blood was collected postoperatively and then given them [their own (autologous) blood] (n = 55). The transfusion trigger for both groups was hemoglobin level of 85 g/L. In the group of patients whose blood was collected perioperatively only 9 (0.9%) of the patients received transfusion of allogeneic blood, as opposed to the control group in which 98.24% of the patients received the transfusion of allogeneic blood (p blood was collected stayed in hospital for 6.18 days, while the patients of the control group stayed 7.67 days (p blood transfusion is a very effective method for reducing consumption of allogenic blood and thus, indirectly for reducing all complications related to allogenic blood transfusion. There is also a positive influence on postoperative recovery after total knee replacement surgery due to the reduction of hospital stay, and indirectly on the reduction of hospital costs.

It has been demonstrated that an extensive resection (total or subtotal) may significantly increase the overall survival in patients with WHO Grade II gliomas (low-grade gliomas [LGGs]). Yet, recent data have shown that conventional MR imaging underestimates the spatial extent of LGG, since tumor cells were found up to 20 mm around MR imaging abnormalities. Thus, it was hypothesized that an extended resection with a margin beyond MR imaging-defined abnormalities-a "supratotal" resection-might improve the outcome of LGG. However, because of the frequent location of LGG within "eloquent" brain areas, it is often difficult to achieve such a supratotal resection. This could nevertheless be possible when LGGs involve "noneloquent" areas, even in the left dominant hemisphere. The authors report on their use of awake electrical mapping to tailor the resection according to functional boundaries, that is, to pursue the resection beyond MR imaging-defined abnormalities, until corticosubcortical eloquent structures are encountered. Their aim was to apply this reliable surgical technique to LGGs located not within eloquent areas but distant from eloquent areas, to take a margin around the LGG visible on MR imaging while preserving brain function. Fifteen right-handed patients with a total of 17 tumors underwent resection of WHO Grade II gliomas involving nonfunctional areas within the left dominant hemisphere. In all patients, seizures were the initial manifestation of the tumors. Awake surgery with intraoperative electrostimulation was performed in all cases. The resection was continued until the surgeon reached cortical and subcortical areas crucial for brain function, especially language, as defined by the intrasurgical electrical mapping. The extent of resection was evaluated on postoperative FLAIR-weighted MR images. Despite transient neurological worsening in 60% of cases, all patients recovered and returned to a normal life. Seizure control was obtained in all patients

C. Politis

2018-06-01

Full Text Available Orthognathic surgery may affect or cause temporomandibular joint (TMJ complaints. This study evaluated the need for TMJ surgery after orthognathic surgery.A retrospective cohort study was carried out on 630 consecutive patients undergoing at least a Le Fort I or bilateral sagittal split osteotomy (BSSO. The mean follow-up time was 2,3 years. Clinical, surgical and radiographic findings were collected.Ten of the 630 patients (1.6% had additional arthroscopic TMJ-surgery in one (9 or in both (1 joints because of internal derangement, resistant to conventional therapy. Only 4/10 patients had successful outcomes following arthroscopic surgery. One patient with unsuccessful outcome required multiple additional open TMJ-surgeries, all remaining ineffective to relieve pain and restricted mouth opening. If arthroscopy failed to relieve symptoms (5/10 patients, further conservative management was opted. Arthroscopy seemed effective mainly in patients without pre-existing TMJ complaints.A further five of the 630 patients (0.8% required more treatment because of bilateral postoperative condylar resorption, but none of them required TMJ-surgery.In contrast to patients with bilateral condylar resorption where the skeletal relapse remained the issue of concern, patients with internal derangement/osteoarthrosis exhibited major occlusal changes in one patient only (1/10, leaving the TMJ complaints as the main concern.

Eighty-five female patients with early stage breast cancer, i.e., Stage I and II were treated by limited surgery followed by radical radiation therapy at Massachusetts General Hospital between January, 1956 and December, 1974. Patients included those who were medically inoperable or who refused mastectomy. The 5-year survival rate was 83% and 76% for Stage I and II, respectively. The corresponding disease free survival (absolute) was 67% and 42%. Although the number of patients so treated is small, there was no significant difference in survival from the results of the radical mastectomy series at the same institution. No major complications were encountered. Seventeen of eighty-five patients developed minor problems; mostly fibrosis and minimal arm lymphedema stemmming from older orthovoltage equipment and treatment techniques. With the current availability of megavoltage equipment, improvements in techniques and dosimetry, complications should decrease. Combined limited surgery and radical radiation therapy should be considered in those patients where a radical mastectomy is not feasible because of psychological or medical problems. Since this procedure results in a cosmetically acceptable breast, radical radiation in early stage breast cancer seems a reasonable alternative to radical mastectomy

The aim of this study was to evaluate the effectiveness of submucosal application of tramadol, for acute postoperative facial pain, following the extraction of impacted third molar teeth. This prospective, double-blind, randomised placebo-controlled study included 60 ASA I-II patients undergoing impacted third molar surgery under local anaesthesia. Following the surgical procedure, patients were randomly divided into two groups; group T (1 mg/kg tramadol) and group S (2-mL saline). Treatments were applied submucosally after surgery. Pain after extraction was evaluated using a visual analogue scale (VAS) 0.5, 1, 2, 4, 6, 12, 24, and 48 h postoperatively. The time at which the first analgesic drug was taken, the total analgesic dose used, and adverse tissue reactions were also evaluated. In group T, postoperative VAS scores were significantly lower compared to that in group S (p pain after impacted third molar surgery.

Afferent loop syndrome: Role of sonography and CT

Energy Technology Data Exchange (ETDEWEB)

Lee, Dong Ho; Lim, Jae Hoon; Ko, Young Tae [Kyung Hee University Hospital, Seoul (Korea, Republic of)

1992-03-15

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of study is to ascertain the sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The cause of ALS, established at surgery, included cancer recurrence (n=4), internal hernia (n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site (n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out often patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The cause of ALS were predicated on the basis of the sonograms in three of the five patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen.Our experience suggests that the diagnosis of afferent syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

Bariatric Surgery as Potential Treatment for Nonalcoholic Fatty Liver Disease: A Future Treatment by Choice or by Chance?

Directory of Open Access Journals (Sweden)

Shuja Hafeez

2013-01-01

Full Text Available Morbid obesity is strongly associated with nonalcoholic fatty liver disease (NAFLD which is one of the most common causes of chronic liver disease worldwide. The current best treatment of NAFLD and NASH is weight reduction through life style modifications, antiobesity medication, and bariatric surgery. Importantly, bariatric surgery is the best alternative option for weight reduction if lifestyle modifications and pharmacological therapy have not yielded long-term success. Bariatric surgery is an effective treatment option for individuals who are grossly obese and associated with marked decrease in obesity-related morbidity and mortality. The most common performed bariatric surgery is Roux-en-Y gastric bypass (RYGB. The current evidence suggests that bariatric surgery in these patients will decrease the grade of steatosis, hepatic inflammation, and fibrosis. NAFLD per se is not an indication for bariatric surgery. Further research is urgently needed to determine (i the benefit of bariatric surgery in NAFLD patients at high risk of developing liver cirrhosis (ii the role of bariatric surgery in modulation of complications of NAFLD like diabetes and cardiovascular disease. The outcomes of the future research will determine whether bariatric surgery will be one of the recommended choice for treatment of the most progressive type of NAFLD.

Prognostic factors for perioperative pulmonary events among patients undergoing upper abdominal surgery

Directory of Open Access Journals (Sweden)

Rafael Luis Sakai

Full Text Available CONTEXT AND OBJECTIVE: The significant relationship between upper abdominal surgery and early (perioperative pulmonary events was investigated among patients with preoperative pulmonary conditions undergoing general anesthesia. DESIGN AND SETTING: Retrospective study for which data were obtained prospectively from 1999 to 2004, at a tertiary university hospital. METHODS: We retrospectively studied 3107 patients over 11 years old presenting American Society of Anesthesiologists (ASA status I, II or III who underwent upper abdominal surgery under general anesthesia and were discharged to the recovery room. The preoperative conditions analyzed using logistic regression were: age, sex, ASA physical status, congestive heart failure, asthma, chronic obstructive pulmonary disease (COPD, respiratory failure and smoking. The outcomes or dependent variables included intraoperative and postoperative events: bronchospasm, hypoxemia, hypercapnia, prolonged intubation and airway secretion. RESULTS: Among these patients (1500 males, 1607 females, mean age 48 years, 1088 ASA I, 1402 ASA II and 617 ASA III, there were 80 congestive heart failures, 82 asthmatics, 122 with COPD, 21 respiratory failures and 428 smokers. Logistic regression analysis showed that female sex (p < 0.001, age over 70 years (p < 0.01, smoking (p < 0.001 and COPD (p < 0.02 significantly influenced pulmonary event development, particularly hypoxemia and bronchospasm, at both times but not in the same patients. Asthma and congestive heart failure cases did not present pulmonary events in the recovery room. CONCLUSION: In upper abdominal surgery under general anesthesia, female sex, age over 70, smoking and COPD were independent risk factors for intra and postoperative pulmonary events.

Abstract The objective of this study was to investigate capsular outcomes 12 months after pediatric cataract surgery without intraocular lens implantation via qualitative classification and quantitative measurement. This study is a cross-sectional study that was approved by the institutional review board of Zhongshan Ophthalmic Center of Sun Yat-sen University in Guangzhou, China. Digital coaxial retro-illumination photographs of 329 aphakic pediatric eyes were obtained 12 months after pediatric cataract surgery without intraocular lens implantation. Capsule digital coaxial retro-illumination photographs were divided as follows: anterior capsule opening area (ACOA), posterior capsule opening area (PCOA), and posterior capsule opening opacity (PCOO). Capsular outcomes were qualitatively classified into 3 types based on the PCOO: Type I—capsule with mild opacification but no invasion into the capsule opening; Type II—capsule with moderate opacification accompanied by contraction of the ACOA and invasion to the occluding part of the PCOA; and Type III—capsule with severe opacification accompanied by total occlusion of the PCOA. Software was developed to quantitatively measure the ACOA, PCOA, and PCOO using standardized DCRPs. The relationships between the accurate intraoperative anterior and posterior capsulorhexis sizes and the qualitative capsular types were statistically analyzed. The DCRPs of 315 aphakic eyes (95.8%) of 191 children were included. Capsular outcomes were classified into 3 types: Type I—120 eyes (38.1%); Type II—157 eyes (49.8%); Type III—38 eyes (12.1%). The scores of the capsular outcomes were negatively correlated with intraoperative anterior capsulorhexis size (R = −0.572, P PCOA increased in size from Type I to Type II, and the PCOO increased from Type II to Type III (all P < 0.05). Capsular outcomes after pediatric cataract surgery can be qualitatively classified and quantitatively measured by acquisition, division

The aim of this study was to evaluate the effect of hybrid technology (laparoscopy and open surgery) for treatment of ovarian cysts in small babies and infants. Between January 2002 and November 2012, we have performed 11 operation for neonatal ovarian cysts repaired through standard circumumbilical incision (Group I) and 16 operation with using combined hybrid laparoscopic-assisted technique (Group II). The circumumbilical incision utilized at our institution is a classic Bianchi procedure. The hybrid approach combined 2 technique - laparoscopic and open. The trocar for optic telescope was inserted through a circumumbilical incision. The one working instrument was introduced into the peritoneal cavity direct through umbilicus. Afterwords, ovarian cyst was deflated with using transabdominal needle aspiration, delivered by an extended umbilical incision and enucleated as in standard open surgery. The two groups were compared for patients demographics, operative report and early postoperative outcomes. All procedures were performed successfully with no complications rate. There were no differences in the preoperative parameters between the two groups. The differences between groups for operative and postoperative results were statistically significant (p<0.05). The mean operative time in Group I was 30.91 min. In contrast, the mean duration of the operation in the Group II was 21.56 min. The mean time to beginning and time of full enteral feeding for patients with hybrid approach were significantly shorter as for patients with umbilical incision (4.06 hours vs 10.91 hours; 13 hours vs 20.55 hours). Prolonged mean postoperative hospital stay were registered in patients of the Group I (6.36 days vs 3.19 days; p<0.05). The postoperative course and follow up was uneventful in the all patients. The experience described in this study confirms that hybrid operation can be applied for treatment of neonatal ovarian cysts with outcomes better than standard open surgery.

Huang, E.-Y.; Sung, C.-C.; Ko, S.-F.; Wang, C.-J.; Yang, Kuender D.

2007-01-01

Purpose: To evaluate the effect of abdominal surgery on the volume effects of small-bowel toxicity during whole-pelvic irradiation in patients with gynecologic malignancies. Methods and Materials: From May 2003 through November 2006, 80 gynecologic patients without (Group I) or with (Group II) prior abdominal surgery were analyzed. We used a computed tomography (CT) planning system to measure the small-bowel volume and dosimetry. We acquired the range of small-bowel volume in 10% (V10) to 100% (V100) of dose, at 10% intervals. The onset and grade of diarrhea during whole-pelvic irradiation were recorded as small-bowel toxicity up to 39.6 Gy in 22 fractions. Results: The volume effect of Grade 2-3 diarrhea existed from V10 to V100 in Group I patients and from V60 to V100 in Group II patients on univariate analyses. The V40 of Group I and the V100 of Group II achieved most statistical significance. The mean V40 was 281 ± 27 cm 3 and 489 ± 34 cm 3 (p 3 and 132 ± 19 cm 3 (p = 0.003). Multivariate analyses revealed that V40 (p = 0.001) and V100 (p = 0.027) were independent factors for the development of Grade 2-3 diarrhea in Groups I and II, respectively. Conclusions: Gynecologic patients without and with abdominal surgery have different volume effects on small-bowel toxicity during whole-pelvic irradiation. Low-dose volume can be used as a predictive index of Grade 2 or greater diarrhea in patients without abdominal surgery. Full-dose volume is more important than low-dose volume for Grade 2 or greater diarrhea in patients with abdominal surgery

Enhanced recovery after surgery is a multimodal perioperative strategy according to the evidence-based medicine and multidisciplinary collaboration, aiming to improve the restoration of functional capacity after surgery by reducing surgical stress, optimal control of pain, early oral diet and early mobilization. Compared with other sub-specialty in general surgery, pancreatic surgery is characterized by complex disease, highly difficult procedure and more postoperative complications. Accordingly, pancreatic surgery shares a slow development in enhanced recovery after surgery. In this review, the feasibility, safety, application progress, prospect and controversy of enhanced recovery after surgery in pancreatic surgery are discussed.

2008-01-01

Richard von Volkmann (1830–1889), one of the most important surgeons of the 19th century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867–1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the “antiseptic technique” to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann’s contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children’s fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

An unstable slipped capital femoral epiphysis (SCFE) is associated with a high rate of avascular necrosis (AVN). The etiology of AVN seems to be multifactorial, although it is not thoroughly known. The aims of our study were to determine the rate of AVN after an unstable SCFE and to investigate the risk factors for AVN, specifically evaluating the notion of an "unsafe window", during which medical interventions would increase the risk for AVN. This retrospective multicenter study included 60 patients with an unstable SCFE diagnosed between 1985 and 2014. Timing of surgery was evaluated for three time periods, from acute onset of symptoms to surgery: period I, 7 days. Multivariate logistic regression analysis was used to identify risk factors for AVN. Closed reduction and pinning was performed in 43 patients and in situ pinning in 17. Among these cases, 16 patients (27%) developed AVN. The rate of AVN was significantly higher in patients treated by closed reduction and pinning (15/43, 35%) than in those treated by in situ pinning (1/17, 5.9%) (p = 0.022). In patients treated by closed reduction and pinning, the incidence of AVN was 2/11 (18%) in period I, 10/13 (77%) in period II and 3/15 (20%) in period III, showing the significantly higher rate in period II (p = 0.002). The surgery provided in period II was identified as an independent risk factor for the development of AVN. Our rate of AVN was 27% using two classical treatment methods. Time-to-surgery, between 24 h and 7 days, was independently associated with AVN, supporting the possible existence of an "unsafe window" in patients with unstable SCFE treated by closed reduction and pinning.

The hierarchy of stability and predictability in orthognathic surgery with rigid fixation: an update and extension

Directory of Open Access Journals (Sweden)

Phillips Ceib

2007-04-01

Full Text Available Abstract A hierarchy of stability exists among the types of surgical movements that are possible with orthognathic surgery. This report updates the hierarchy, focusing on comparison of the stability of procedures when rigid fixation is used. Two procedures not previously placed in the hierarchy now are included: correction of asymmetry is stable with rigid fixation and repositioning of the chin also is very stable. During the first post-surgical year, surgical movements in patients treated for Class II/long face problems tend to be more stable than those treated for Class III problems. Clinically relevant changes (more than 2 mm occur in a surprisingly large percentage of orthognathic surgery patients from one to five years post-treatment, after surgical healing is complete. During the first post-surgical year, patients treated for Class II/long face problems are more stable than those treated for Class III problems; from one to five years post-treatment, some patients in both groups experience skeletal change, but the Class III patients then are more stable than the Class II/long face patients. Fewer patients exhibit long-term changes in the dental occlusion than skeletal changes, because the dentition usually adapts to the skeletal change.

Proteolysis of IGFBP-3 is generally believed to increase IGF bioavailability due to a diminished affinity of the IGFBP-3 fragments for IGFs. We have investigated 18 patients...... undergoing elective ileo-anal J-pouch surgery. Patients were randomized to treatment with GH (12 IU/day; n = 9) or placebo (n = 9) from 2 days before to 7 days after operation. Free IGF-I and IGF-II were measured by ultrafiltration of serum, and IGFBP-3 proteolytic activity was determined by a [125I...

Postoperative cardiovascular complications might be difficult to assess and are known to be associated with longer hospital stay and increased costs as well as higher morbidity and mortality rates. The aim of this study was to evaluate the predictors for major cardiac events (MCE) after non-cardiac surgery. The study included 4398 patients who were admitted to the Surgical Intensive Care Unit between January 1, 2006 and July 19, 2013. Acute physiology and chronic health evaluation II score and simplified acute physiology score (SAPS II) were calculated, and all variables entered as parameters were evaluated independently. Multivariate logistic regression analysis was performed to assess the independent factors for MCE. A total of 107 people experienced MCE. The independent predictors for postoperative MCE were higher fraction of inspired oxygen (FiO2) (odds ratio [OR] 38.97; 95 % confidence interval [CI] 10.81-140.36), history of ischemic heart disease (OR 3.38; 95 % CI 2.12-5.39), history of congestive heart disease (OR 2.39; 95 % CI 1.49-3.85), history of insulin therapy for diabetes (OR 2.93; 95 % CI 1.66-5.19), and increased SAPS II (OR 1.03; 95 % CI 1.01-1.05). Having a MCE was associated with a longer length of stay in the surgical intensive care unit (OR 1.01, 95 % CI 1.00-1.01). FiO2, ischemic heart disease, congestive heart disease, insulin therapy for diabetes, SAPS II, and length of stay in the surgical intensive care unit were independent predictors for MCE.

Full Text Available Objectives: Peribulbar anesthesia is associated with delayed and/or incomplete orbital akinesia compared with retrobulbar anesthesia. This study examined the effects of adding rocuronium 5 mg to two different concentrations of lidocaine-bupivacaine mixture on onset time of orbital and eyelid akinesia in patients undergoing cataract surgery. Methods: In a double-blind study, 90 patients were equally randomized to receive a mixture of 0.5 ml normal saline, 4 ml lidocaine 2%, and 4 ml bupivacaine 0.5% (group I, a mixture of rocuronium 0.5 ml (5 mg, 4 ml lidocaine 2%, and 4 ml bupivacaine 0.5% (group II, or a mixture of rocuronium 0.5 ml (5 mg, 4 ml lidocaine 1%, and 4 ml bupivacaine 0.25% (group III. Orbital akinesia was assessed on a 0-8 score (0 = no movement, 8 = normal at 2 min intervals for 10 min. Time to adequate anesthesia was also recorded. Results are presented as mean±SD. Results: Ocular movement score decreased during the assessment period in all groups. However, at 2 min after block administration, the score decreased to 4±2 (95% CI 3,5 in groups II and III compared with 5±2 (95% CI 4,6 in group I (P<0.01. Time to adequate condition to begin surgery was 9.8±2.9 vs. 6.9±4.1 vs. 7.9±3.9 min for groups I, II, and III, respectively (P=0.01. Conclusion: The addition of rocuronium 5 mg to a mixture of lidocaine 2% and bupivacaine 0.5% shortened the onset time of peribulbar anesthesia in patients undergoing cataract surgery without causing adverse effects.

This study assessed loss of control (LOC) eating and eating disorders (EDs) in adolescents undergoing bariatric surgery for severe obesity. Preoperative baseline data from the Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) multisite observational study (n = 242; median BMI = 51 kg/m 2 ; mean age= 17; 76% female adolescents; 72% Caucasian) included anthropometric and self-report questionnaires, including the Questionnaire of Eating and Weight Patterns-Revised (QEWP-R), the Night Eating Questionnaire (NEQ), the Beck Depression Inventory (BDI-II), and the Impact of Weight on Quality of Life-Kids (IWQOL-Kids) RESULTS: LOC eating (27%) was common and ED diagnoses included binge-eating disorder (7%), night eating syndrome (5%), and bulimia nervosa (1%). Compared to those without LOC eating, those with LOC eating reported greater depressive symptomatology and greater impairment in weight-related quality of life. Before undergoing bariatric surgery, adolescents with severe obesity present with problematic disordered eating behaviors and meet diagnostic criteria for EDs. LOC eating, in particular, was associated with several negative psychosocial factors. Findings highlight targets for assessment and intervention in adolescents before bariatric surgery. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:947-952). © 2016 Wiley Periodicals, Inc.

The purpose of this study was to clarify the impact of orthognathic surgery on oral health-related quality of life (OHRQOL) in patients with jaw deformities. The subjects were 65 patients (21 males and 44 females) who underwent orthognathic surgery. The mean age of the patients was 23.6 years. Forty-seven patients had skeletal class III malocclusions, eight patients had skeletal class II, and 10 patients had skeletal class I with facial asymmetry and/or open bite. OHRQOL was assessed using the Japanese version of the Oral Health Impact Profile (OHIP-J54) before and 6 months after surgery. While OHIP-J54 scores in the patients before surgery were significantly higher than those in the control subjects, OHIP-J54 scores after surgery were significantly lower than those before surgery. OHIP-J54 scores in older patients were significantly higher than those in younger patients. In conclusion, most patients with jaw deformities have lower OHRQOL than individuals with normal occlusion, and orthognathic surgery has a positive impact on OHRQOL. The determination of OHRQOL in patients with jaw deformities seems to be very useful for understanding the patients' problems and for assessing the extent of changes in terms of patient well-being.

Patients suffering from body dysmorphic disorder (bdd) are preoccupied with a slight or imagined defect in appearance. First of all, to review the literature on the prevalence of bdd in cosmetic surgery and thereafter to review the literature on psychiatric comorbidity and the outcome of surgical interventions. We based our search strategy on Embase, Medline and PubMed, using the search terms 'body dysmorphic disorder', 'cosmetic surgery', 'prevalence', 'comorbidity' and 'outcome'. Our search covered English and Dutch literature published after the introduction of bdd in dsm-iii-r and before 1 November, 2013. A study of the relevant articles enabled us to access additional articles mentioned in these texts. Our initial search strategy turned out to be too narrow. It was therefore broadened to include 'body dysmorphic disorder', 'cosmetic surgery', and 'prevalence'. Eventually we included 23 original articles. In 11 of these the prevalence of bdd varied from 3.2 to 53.6%. Twelve articles on psychiatric comorbidity revealed predominantly mood and anxiety disorders on axis I and cluster C personality disorders on axis II. Only two studies reported on the outcome of cosmetic surgery performed on bdd patients; surgical interventions, however, seemed to result in new preoccupations with the prolongation of psychiatric comorbidity. bdd is a common psychiatric disorder that can sometimes lead to cosmetic surgery. However, pre-operative screening of bdd patients is vital so that efficient psychiatric treatment can be initiated and patients are not subjected to surgical interventions which may be ineffective or even harmful.

Enhanced Recovery After Surgery Protocols in Major Urologic Surgery

Full Text Available The purpose of the reviewThe analysis of the components of enhanced recovery after surgery (ERAS protocols in urologic surgery.Recent findingsERAS protocols has been studied for over 20 years in different surgical procedures, mostly in colorectal surgery. The concept of improving patient care and reducing postoperative complications was also applied to major urologic surgery and especially procedure of radical cystectomy. This procedure is technically challenging, due to a major surgical resection and high postoperative complication rate that may reach 65%. Several clinical pathways were introduced to improve perioperative course and reduce the length of hospital stay. These protocols differ from ERAS modalities in other surgeries. The reasons for this are longer operative time, increased risk of perioperative transfusion and infection, and urinary diversion achieved using transposed intestinal segments. Previous studies in this area analyzed the need for mechanical bowel preparation, postoperative nasogastric tube decompression, as well as the duration of urinary drainage. Furthermore, the attention has also been drawn to perioperative fluid optimization, pain management, and bowel function.SummaryNotwithstanding partial resemblance between the pathways in major urologic surgery and other pelvic surgeries, there are still scarce guidelines for ERAS protocols in urology, which is why further studies should assess the importance of preoperative medical optimization, implementation of thoracic epidural anesthesia and analgesia, and perioperative nutritional management.

Anesthesia for arthroscopic shoulder surgery is challenging due to the need for oligaemic surgical field as well as a good postoperative recovery profile. The present study was prospective, randomized to evaluate the efficacy of dexmdetomidine infusion compared to that of fentanyl in patients undergoing arthroscopic shoulder surgery under general anesthesia. A total of 60 patients aged from thirty to fifty years, American Society of Anesthesiologists Class I/II of either sex for arthroscopic shoulder surgery, were included. The patients were divided into two groups of 30 patients each. Group I received dexmedetomidine loading 1 μg/kg over 10 min followed by maintenance 0.5 μg/kg/h and Group II Fentanyl loading 1 μg/kg followed by maintenance 0.5 μg/kg/h. Hemodynamic readings (Heart rate HR, and mean arterial blood pressure MAP) were recorded after the start of the study drug infusion (T1), after intubation (T2), then every 15 minutes till the end of surgery (T15, T30, T45, T60, T75, T90). In the PACU, MAP, and HR were recorded on arrival, after 30 min, 1 hr, and 2 hrs (R0, R30, R1 hr, R2 hr) Postoperative analgesia was assessed by visual analogue scale (VAS), Modified Observers's Assessment of Alertness and Sedation OAA/S was recorded on arrival to PACU. This study showed that in the dexmedatomidine group there was statistically significant decrease of MAP and HR after drug infusion up to two hours in the recovery period, more sedation, better control of pain and surgeon satisfaction. Iv infusion of dexamedatomidine may be an attractive option during arthroscopic shoulder surgery as it provided a better hypotensive anesthesia by lowering MAP and HR which leads to better surgical field and surgeon satisfaction than iv infusion fentanyl along with a better postoperative VAS.

Ignaz Philipp Semmelweis, the prophet of bacteriology.

Although by 1931 I. Ph. Semmelweis' achievements and the tragedy of his life had been given their due place in the history of mankind, Alexander Fränkel, formerly Theodor Billroth's assistant and later his biographer, critically stated that the discoverer of the causes of puerperal fever should have defended his discovery with facts rather than with fanaticism. It was only a few years after Semmelweis' death, for instance, that Billroth made laborious experiments. Billroth's work on Coccobacteria had important implications and even influenced Robert Koch, although his hypotheses did not really predict the pathogenic and specific nature of microbes. In 1847 Semmelweis postulated his theory; ie, that the pathological-anatomical changes which he observed in the bodies of the women who died in childbed, in their newborn infants, and in the autopsy findings on his friend Jakob Kolletschka were an entity, morphologically and clinically. He summed them up under the concept of pyemia. Even though Semmelweis was continually abhorred by the evident statistics and would have been able to prove his discovery through animal experiments, he primarily took to the pen to defend his opinion vehemently. Only the clinical facts proved him right during his lifetime; the triumph of bacteriology which began after his death made him not only the "savior of mothers" but also a genial ancestor of bacteriology.

Piezosurgery (piezoelectric bone surgery) devices were developed to cut bone atraumatically using ultrasonic vibrations and to provide an alternative to the mechanical and electrical instruments used in conventional oral surgery. Indications for piezosurgery are increasing in oral and maxillofacial surgery, as in other disciplines, such as endodontic surgery. Key features of piezosurgery instruments include their ability to selectively cut bone without damaging adjacent soft tissue, to provide a clear operative field, and to cut without generating heat. Although piezosurgery instruments can be used at most stages of endodontic surgery (osteotomy, root-end resection, and root-end preparation), no published data are available on the effect of piezosurgery on the outcomes of endodontic surgery. To our knowledge, no study has evaluated the effect of piezosurgery on root-end resection, and only 1 has investigated root-end morphology after retrograde cavity preparation using piezosurgery. We conducted a search of the PubMed and Cochrane databases using appropriate terms and keywords related to the use and applications of piezoelectric surgery in endodontic surgery. A hand search also was conducted of issues published in the preceding 2 years of several journals. Two independent reviewers obtained and analyzed the full texts of the selected articles. A total of 121 articles published between January 2000 and December 2013 were identified. This review summarizes the operating principles of piezoelectric devices and outlines the applications of piezosurgery in endodontic surgery using clinical examples. Piezosurgery is a promising technical modality with applications in several aspects of endodontic surgery, but further studies are necessary to determine the influence of piezosurgery on root-end resection and root-end preparation.

Brilhault, Jean; Noël, Vincent

2012-10-01

The decision to offer surgery for Stage II posterior tibial tendon deficiency (PTTD) is a difficult one since orthotic treatment has been documented to be a viable alternative to surgery at this stage. Taking this into consideration we limited our treatment to bony realignment by a lengthening calcaneus Evans osteotomy and tendon balancing. The goal of the study was to clinically evaluate PTT functional recovery with this procedure. The patient population included 17 feet in 13 patients. Inclusion was limited to early Stage II PTTD flatfeet with grossly intact but deficient PTT. Deficiency was assessed by the lack of hindfoot inversion during single heel rise test. The surgical procedure included an Evans calcaneal opening wedge osteotomy with triceps surae and peroneus brevis tendon lengthening. PTT function at follow up was evaluated by an independent examiner. Evaluation was performed at an average of 4 (range, 2 to 6.3) years. One case presented postoperative subtalar pain that required subtalar fusion. Every foot could perform a single heel rise with 13 feet having active inversion of the hindfoot during elevation. The results of this study provide evidence of PTT functional recovery without augmentation in early Stage II. It challenges our understanding of early Stage II PTTD as well as the surgical guidelines recommending PTT augmentation at this specific stage.

To report the results of a phase II trial combining celecoxib and preoperative chemoradiotherapy (CRT) for locally advanced rectal cancer. Patients with clinical stage II or III rectal cancer were treated with radiotherapy of 44 Gy in 22 fractions. Concurrent chemotherapy consisted of oral tegafur-uracil and folinate on days 1-30 and 38-65. Celecoxib (400 mg/day) given from days 1 to 65. Surgery was done on day 70. The expression of cyclooxygenase 2 (COX-2) in tumor tissues was evaluated microscopically as a prognostic factor. From 2008 to 2011, 53 patients completed CRT+ celecoxib therapy and 47 received radical surgery. Grade 3 diarrhea developed in 5 (9%). Grade 4 anemia was seen in 2 (4%). Pathological complete response (pCR) was seen in 6 (13%). T or N downstaging found in 38 (81%). Sphincter preservation was achieved in 77% of low-positioned tumors. Patients with tumors expressing high-level COX-2 after CRT + celecoxib treatment had inferior pelvic control (P = 0.01), disease-free survival (P = 0.04), and overall survival (P = 0.03) than those with low-level expression. Celecoxib can be safely combined with preoperative CRT for rectal cancer. More intensified adjuvant therapy may be considered for tumors expressing high-level COX-2 after CRT and surgery. © 2013 Wiley Periodicals, Inc.

Two commonly performed surgical interventions are available for severe (grade II-IV) haemorrhoids; traditional excisional surgery and stapled haemorrhoidopexy. Uncertainty exists as to which is most effective. The eTHoS trial was designed to establish the clinical effectiveness and cost-effectiveness of stapled haemorrhoidopexy compared with traditional excisional surgery. The eTHoS trial was a large, open-label, multicentre, parallel-group, pragmatic randomised controlled trial done in adult participants (aged 18 years or older) referred to hospital for surgical treatment for grade II-IV haemorrhoids. Participants were randomly assigned (1:1) to receive either traditional excisional surgery or stapled haemorrhoidopexy. Randomisation was minimised according to baseline EuroQol 5 dimensions 3 level score (EQ-5D-3L), haemorrhoid grade, sex, and centre with an automated system to stapled haemorrhoidopexy or traditional excisional surgery. The primary outcome was area under the quality of life curve (AUC) measured with the EQ-5D-3L descriptive system over 24 months, assessed according to the randomised groups. The primary outcome measure was analysed using linear regression with adjustment for the minimisation variables. This trial is registered with the ISRCTN registry, number ISRCTN80061723. Between Jan 13, 2011, and Aug 1, 2014, 777 patients were randomised (389 to receive stapled haemorrhoidopexy and 388 to receive traditional excisional surgery). Stapled haemorrhoidopexy was less painful than traditional excisional surgery in the short term and surgical complication rates were similar between groups. The EQ-5D-3L AUC score was higher in the traditional excisional surgery group than the stapled haemorrhoidopexy group over 24 months; mean difference -0·073 (95% CI -0·140 to -0·006; p=0·0342). EQ-5D-3L was higher for stapled haemorrhoidopexy in the first 6 weeks after surgery, the traditional excisional surgery group had significantly better quality of life

With a focus on providing high quality care and reducing facility based expenses there has been an evolution in perioperative care by way of enhanced recovery after surgery (ERAS). ERAS allows for a multidisciplinary and multimodal approach to perioperative care which not only expedites recovery but maximizes patient outcomes. This paradigm shift has been generally accepted by most surgical specialties, including plastic surgery. The goal of this study was to evaluate the impact of ERAS on outcomes in cosmetic plastic surgery. A prospective study consisting of phone call questionnaires was designed where patients from two senior plastic surgeons (N.H.R. and J.D.F.) were followed. The treatment group (n = 10) followed an ERAS protocol while the control group (n = 12) followed the traditional recovery after surgery which included narcotic usage. Patients were contacted on postoperative days (POD) 0 through 7+ and surveyed about a number of outcomes measures. The ERAS group demonstrated a significant reduction in postoperative pain on POD 0, 1, 2, and 3 (all P plastic surgery. The utility lies in the ability to expedite patient's recovery while still providing quality care.

2009-12-01

To identify relevant questions related to sex definition and re-designation and reconstructive surgery in patients with congenital adrenal hyperplasia (CAH), and to understand the role of the psychologist in providing care for these patients. We selected 21 subjects: 7 pediatric endocrinologists from 5 Brazilian Public Health System institutions, 9 parents and 6 patients with CAH, according to a qualitative research model. In this paper, 3 of the studied categories are analyzed: 'sex definition and re-designation', 'reconstructive surgery/vaginal dilation', and 'psychology'. Parents' main anguish relates to the situation of an unnamed sex at birth, whereas sex re-designation was distressful to physicians. A sense of loneliness when dealing with the disease and treatment was a common anguish among patients; dilation procedures were the major complaint. In general, physicians recommend that genital reconstructive surgery be performed early on to avoid future trauma. In such a complex scenario, it is remarkable that not all the reference service staff have a psychologist on duty. Difficulties to deal with questions involving sexuality were evident and dilation procedures are an additional source of trauma for these patients.

This paper describes an adult Saudi male patient who presented with a severe skeletal class II deformity. The case was managed with a combination of presurgical orthodontic treatment followed by a double jaw orthognathic surgery and then another phase of orthodontic treatment for final occlusal detailing. Extraction of the four first premolars was done during the presurgical orthodontic phase of treatment to decompensate upper and lower incisors and to give room for surgical setback of the maxillary anterior segment. Double jaw surgery was performed: bilateral sagittal split ramus osteotomy for 8 mm mandibular advancement combined with three-piece Le Fort I maxillary osteotomy, 6 mm setback of the anterior segment, 8 mm impaction of the maxilla, and 5 mm advancement genioplasty. Although the anteroposterior discrepancy and the facial convexity were so severe, highly acceptable results were obtained, both esthetically as well as occlusally. PMID:23573428

The objective of the study was to assess common practice in pediatric epilepsy surgery in Italy between 2008 and 2014. A survey was conducted among nine Italian epilepsy surgery centers to collect information on presurgical and postsurgical evaluation protocols, volumes and types of surgical interventions, and etiologies and seizure outcomes in pediatric epilepsy surgery between 2008 and 2014. Retrospective data on 527 surgical procedures were collected. The most frequent surgical approaches were temporal lobe resections and disconnections (133, 25.2%) and extratemporal lesionectomies (128, 24.3%); the most frequent etiologies were FCD II (107, 20.3%) and glioneuronal tumors (105, 19.9%). Volumes of surgeries increased over time independently from the age at surgery and the epilepsy surgery center. Engel class I was achieved in 73.6% of patients (range: 54.8 to 91.7%), with no significant changes between 2008 and 2014. Univariate analyses showed a decrease in the proportion of temporal resections and tumors and an increase in the proportion of FCDII, while multivariate analyses revealed an increase in the proportion of extratemporal surgeries over time. A higher proportion of temporal surgeries and tumors and a lower proportion of extratemporal and multilobar surgeries and of FCD were observed in low (epilepsy surgery in Italy between 2008 and 2014, associated with a stable seizure outcome.

Surgical specialty procedures in rural surgery practices: implications for rural surgery training.

Science.gov (United States)

Sticca, Robert P; Mullin, Brady C; Harris, Joel D; Hosford, Clint C

2012-12-01

Specialty procedures constitute one eighth of rural surgery practice. Currently, general surgeons intending to practice in rural hospitals may not get adequate training for specialty procedures, which they will be expected to perform. Better definition of these procedures will help guide rural surgery training. Current Procedural Terminology codes for all surgical procedures for 81% of North Dakota and South Dakota rural surgeons were entered into the Dakota Database for Rural Surgery. Specialty procedures were analyzed and compared with the Surgical Council on Resident Education curriculum to determine whether general surgery training is adequate preparation for rural surgery practice. The Dakota Database for Rural Surgery included 46,052 procedures, of which 5,666 (12.3%) were specialty procedures. Highest volume specialty categories included vascular, obstetrics and gynecology, orthopedics, cardiothoracic, urology, and otolaryngology. Common procedures in cardiothoracic and vascular surgery are taught in general surgical residency, while common procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology are usually not taught in general surgery training. Optimal training for rural surgery practice should include experience in specialty procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology. Copyright © 2012 Elsevier Inc.

Intraoperative hemidiaphragm electrical stimulation reduces oxidative stress and upregulates autophagy in surgery patients undergoing mechanical ventilation: exploratory study

Directory of Open Access Journals (Sweden)

Robert T. Mankowski

2016-10-01

Full Text Available Abstract Background Mechanical ventilation (MV during a cardio-thoracic surgery contributes to diaphragm muscle dysfunction that impairs weaning and can lead to the ventilator- induced diaphragm dysfunction. Especially, it is critical in older adults who have lower muscle reparative capacity following MV. Reports have shown that the intraoperative intermittent hemidiaphragm electrical stimulation can maintain and/or improve post-surgery diaphragm function. In particular, from a molecular point of view, intermittent electrical stimulation (ES may reduce oxidative stress and increase regulatory autophagy levels, and therefore improve diaphragm function in animal studies. We have recently shown in humans that intraoperative ES attenuates mitochondrial dysfunction and force decline in single diaphragm muscle fibers. The aim of this study was to investigate an effect of ES on oxidative stress, antioxidant status and autophagy biomarker levels in the human diaphragm during surgery. Methods One phrenic nerve was simulated with an external cardiac pacer in operated older subjects (62.4 ± 12.9 years (n = 8 during the surgery. The patients received 30 pulses per min every 30 min. The muscle biopsy was collected from both hemidiaphragms and frozen for further analyses. 4-hydroxynonenal (4-HNE, an oxidative stress marker, and autophagy marker levels (Beclin-1 and the ratio of microtubule-associated protein light chain 3, I and II-LC3 II/I protein concentrations were detected by the Western Blot technique. Antioxidant enzymatic activity copper-zinc (CuZnSOD and manganese (MnSOD superoxide dismutase were analyzed. Results Levels of lipid peroxidation (4-HNE were significantly lower in the stimulated side (p  0.05. Additionally, the protein concentrations of Beclin-1 and the LC3 II/I ratio were higher in the stimulated side (p < 0.05. Conclusion These results suggest that the intraoperative electrical stimulation decreases oxidative stress levels

The optimal treatment strategy for stage I-II glottic squamous cell carcinoma (SCC) is not well-defined. This study analyzed treatment results and prognostic factors. This is a single-institution retrospective analysis of 244 patients with T1-2 glottic SCC who underwent normofractionated radiotherapy (RT) and/or surgery between 1990 and 2013. The primary endpoint was relapse-free survival (RFS). Median age was 65 years (range: 36-92 years), the majority (82%) having stage I disease. Definitive RT was used in 82% (median dose: 68 Gy, 2 Gy per fraction). Median follow-up was 59 months. The 5-year RFS rates were 83 and 75% (p = 0.05) for stage I and 62 and 50% (p = 0.47) for stage II in the RT and surgery groups, respectively. Multivariate analyses indicate T1 vs. T2 and RT vs. surgery as independent prognostic factors for RFS, with hazard ratios of 0.38 (95% confidence interval, CI: 0.21-0.72) and 0.53 (95% CI: 0.30-0.99), respectively (p < 0.05). The 5-year overall and cause-specific survival rates in the whole cohort were 92 and 96%, respectively, with no significant differences between treatment groups. Anterior commissure involvement was neither a prognostic nor a predictive factor. The incidence of secondary malignancies was not significantly different between patients treated with and without RT (22 vs. 9% at 10 years, respectively, p = 0.18). Despite a possible selection bias, our series demonstrates improved RFS with RT over surgery in stage I glottic SCC. (orig.)

The disadvantages of having orthodontic interventions both before and after orthognathic surgery include a long treatment time of 7-47 months and temporary worsening of facial appearance. Nowadays, the concept of surgery-first, followed by orthodontic treatment is applied to orthognathic surgery cases in different orthodontic centers in the world. This concept and technique is called "surgery-first-orthognathic-approach" or "surgery-first approach" (SFA) rigid fixation (skeletal anchorage system) of the bony segments and regional acceleratory phenomenon were keys to broad implementation of the SFA. This article is intended to provide an overview of SFA including indications, general and specific guidelines, different protocol variations, success rate and potential problems.

We have developed an intraoperative radiotherapy technique in breast-conserving surgery. Following lumpectomy and axillary dissection up to Level II, the subcutaneous fat layer was lifted from the gland over the entire breast. Electron beams of 25 Gy were irradiated within cylinder, avoiding the skin and subcutaneous tissue. The surface of the gland was covered with cotton swabs saturated with normal saline to equalize the energy depth to the chest wall. This technique has so far been applied to 8 patients, all of whom went through a successful postoperative period without serious complications. The cosmetic results were satisfactory from immediately after the operation. Intraoperative radiotherapy combined with breast-conserving surgery may be helpful in improving the QOL of patients by eliminating the adverse effects associated radiation injury to the skin of the breast and long-term postoperative follow-up.

Primary aim was to modify Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ) to assess pelvic organ prolapse (POP) in Arabic Muslim women. Secondary aim was to compare functional and anatomical outcomes of POP repair. Questionnaire. A characteristic (prayer) was added to PFIQ. Linguistic validation of questionnaires was then done. Twenty cases were enrolled in a pilot study to test internal consistency and reliability. Subsequent study. Prospective study included women with symptomatic POP >or= stage II. History, examination by POP-Q, and administration of PFDI and PFIQ, were done before and 6 months after surgery. Questionnaire. Internal consistency of added question was good (Cronbach alpha = 0.78). Test-retest reliability of individual PFIQ items was variable. Subsequent Study. Between September 2004 and February 2007, 78 consecutive women were included. Cystocele, rectocele, and no site predominated in 74.4%, 17.9% and 7.7% of cases, respectively. Preoperatively 19.2%, 15.4% and 47.4% reported stress, urge, and mixed incontinence, respectively. Overall and individual urinary symptoms scores improved significantly after surgery. There were significant improvements in individual symptoms of constipation, splint to defecate and losing not well formed stools. Low self-esteem was most negative impact of prolapse on quality of life (QoL) followed by prayer. After surgery 90% of subjects had anatomical cure. After surgery, QoL issues are significantly related to anatomic location of prolapse as determined by POP-Q. Modified PFIQ and PFDI are suitable to assess POP among Muslim women. Postoperatively, many prolapse-related symptoms and QoL significantly improve after surgery on the short term with an anatomic cure rate of 90%.

Minimal access surgery has revolutionized surgery practice. Its proven advantages, such as reduced postoperative pain, early return to unrestricted activities, and better cosmesis, have become important drivers for its rapid development. In sub-Saharan Africa this development has been slow. The aim of the current study was to describe the challenges and outcomes of laparoscopic procedures in a public hospital that caters to a predominantly rural population. The first 100 patients who underwent laparoscopic procedure in the Department of Surgery at Federal Medical Centre, Owerri, Nigeria were retrospectively analyzed. Data were retrieved from the medical records department as well as the surgical theater procedure register. The focus of the study was on patient demographics, indication for surgery, procedure performed, length of hospital stay, and morbidity and mortality data. Staff training was done locally and abroad. Altogether, 100 patients had laparoscopic surgery in our general surgery unit from September 2007 through July 2013. The ages of the patients was 5-75 years (median 36.5 years). The three main procedures were cholecystectomy (36 %), diagnostic laparoscopy (29 %), and appendectomy (21 %). The other operations performed included liver abscess drainage (7 %), adhesiolysis (3 %), hernia repair (1 %), and Heller's myotomy (1 %). Four cases were converted to open surgery. There were no deaths. There were 14 grades I and II postoperative complications in nine patients. Our study suggests that basic laparoscopic procedures could be offered safely to our resource-poor rural population. It is a platform on which we can hopefully introduce advanced laparoscopic surgical operations.

Full Text Available Iron(II, cobalt(II, nickel (II, copper (II, zinc(II and cadmium(II complexes of the type ML2Cl2, where M is a metal and L is the Schiff base N-(2-thienylmethylenemethanamine (TNAM formed by the condensation of 2-thiophenecarboxaldehyde and methylamine, were prepared and characterized by elemental analysis as well as magnetic and spectroscopic measurements. The elemental analyses suggest the stoichiometry to be 1:2 (metal:ligand. Magnetic susceptibility data coupled with electronic, ESR and Mössbauer spectra suggest a distorted octahedral structure for the Fe(II, Co(II and Ni(II complexes, a square-planar geometry for the Cu(II compound and a tetrahedral geometry for the Zn(II and Cd(II complexes. The infrared and NMR spectra of the complexes agree with co-ordination to the central metal atom through nitrogen and sulphur atoms. Conductance measurements suggest the non-electrolytic nature of the complexes, except for the Cu(II, Zn(II and Cd(II complexes, which are 1:2 electrolytes. The Schiff base and its metal chelates were screened for their biological activity against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa and the metal chelates were found to possess better antibacterial activity than that of the uncomplexed Schiff base.

Traumatic First Time Shoulder Dislocation: Surgery vs Non-Operative Treatment

Directory of Open Access Journals (Sweden)

Ioannis Polyzois

2016-04-01

Full Text Available Management of first shoulder dislocation following reduction remains controversial. The two main options are immobilisation and arthroscopic stabilisation. The aim of this article is to highlight some of the issues that influence decision making when discussing management options with these patients, including natural history of the first time dislocation, outcomes of surgery and non-operative management particularly on the risk of future osteoarthritis (OA, the effects of delaying surgery and the optimal method of immobilisation. Extensive literature review was performed looking for previous publication addressing 4 points. i Natural history of primary shoulder dislocation ii Effect of surgical intervention on natural history iii Risk of long term osteoarthritis with and without surgical intervention iv Immobilisation techniques post reduction. Individuals younger than 25 years old are likely to re-dislocate with non-operative management. Surgery reduces risk of recurrent instability. Patients with recurrent instability appear to be at a higher risk of OA. Those who have surgical stabilisation do not appear to be at a higher risk than those who dislocate just once, but are less likely to develop OA than those with recurrent instability. Delaying surgery makes the stabilisation more demanding due to elongation of capsule, progressive labro-ligamentous injury, prevalence and severity of glenoid bone loss. Recent studies have failed to match the preliminary outcomes associated with external rotation braces. Defining the best timing and type of treatment remains a challenge and should be tailored to each individual’s age, occupation and degree of physical activity.

Objective: To evaluate the impact of postoperative adjuvant radiotherapy, compared with surgery alone for rectal cancer. Methods: From January 1994 to October 1997, 192 patients with stage II or III rectal cancer were treated by radical resection and postoperative radiotherapy (Group S + R) and 51 patients with the same stage lesions underwent surgery alone (Group S). The median dose of radiation was 50(32-62) Gy. Kaplan-Meier method and Log-rank test were used for analysis. Results: The 5-year overall and disease-free survival rates were 60.3% and 58.3%, respectively. The overall 5-year survival rate was 59.4% in Group S + R and 64.7% in Group S, and the 5-year disease-free survival rates were 57.0% and 66.4%, respectively. There were no significant differences between either group (P=0.601 and P=0.424). The disease-free survival was not significantly prolonged in Group S + R as compared with that of Group S. The local recurrence rate was evidently reduced in Group S + R (15.8% v 26.8%, P=0.043). Conclusion: Local recurrence is a major cause of morbidity and mortality in rectal cancer. Postoperative radiotherapy, though reduces the incidence of local recurrence, does not improve the survival in the treatment of stage II and III diseases

DEVELOPMENT OF PLASTIC SURGERY.

Plastic surgery is a medical specialty dealing with corrections of defects, improvements in appearance and restoration of lost function. Ancient times. The first recorded account of reconstructive plastic surgery was found in ancient Indian Sanskrit texts, which described reconstructive surgeries of the nose and ears. In ancient Greece and Rome, many medicine men performed simple plastic cosmetic surgeries to repair damaged parts of the body caused by war mutilation, punishment or humiliation. In the Middle Ages, the development of all medical braches, including plastic surgery was hindered. New age. The interest in surgical reconstruction of mutilated body parts was renewed in the XVIII century by a great number of enthusiastic and charismatic surgeons, who mastered surgical disciplines and became true artists that created new forms. Modern era. In the XX century, plastic surgery developed as a modern branch in medicine including many types of reconstructive surgery, hand, head and neck surgery, microsurgery and replantation, treatment of burns and their sequelae, and esthetic surgery. Contemporary and future plastic surgery will continue to evolve and improve with regenerative medicine and tissue engineering resulting in a lot of benefits to be gained by patients in reconstruction after body trauma, oncology amputation, and for congenital disfigurement and dysfunction.

Gow, Kenneth W.; Drake, F. Thurston; Aarabi, Shahram; Waldhausen, John H.

2014-01-01

Background General surgery (GS) residents in ACGME programs log cases performed during their residency. We reviewed designated pediatric surgery (PS) cases to assess for changes in performed cases over time. Methods The ACGME case logs for graduating GS residents were reviewed from academic year (AY) 1989–1990 to 2010–2011 for designated pediatric cases. Overall and designated PS cases were analyzed. Data were combined into five blocks: Period I (AY1989–90 to AY1993–94), Period II (AY1994–95 to AY1998–99), Period III (AY1999–00 to AY2002–03), Period IV (AY2003–04 to AY2006–07), and Period V (AY2007–08 to AY2010–11). Periods IV and V were delineated by implementation of duty hour restrictions. Student t-tests compared averages among the time periods with significance at P < .05. Results Overall GS case load remained relatively stable. Of total cases, PS cases accounted for 5.4% in Period I and 3.7% in Period V. Designated pediatric cases declined for each period from an average of 47.7 in Period I to 33.8 in Period V. These changes are due to a decline in hernia repairs, which account for half of cases. All other cases contributed only minimally to the pediatric cases. The only laparoscopic cases in the database were anti-reflux procedures, which increased over time. Conclusions GS residents perform a diminishing number of designated PS cases. This decline occurred before the onset of work-hour restrictions. These changes have implications on the capabilities of the current graduating workforce. However, the case log does not reflect all cases trainees may be exposed to, so revision of this list is recommended. PMID:23932601

The European educational platform on thoracic surgery.

Massard, Gilbert; Rocco, Gaetano; Venuta, Federico

2014-05-01

As the largest scientific organisation world-wide exclusively dedicated to general thoracic surgery (GTS), the European Society of Thoracic Surgeons (ESTS) recognized that one of its priorities is education. The educational platform designed ESTS addresses not only trainees, but also confirmed thoracic surgeons. The two main aims are (I) to prepare trainees to graduation and to the certification by the European Board of Thoracic Surgery and (II) to offer opportunities for continuous medical education in the perspective of life-long learning and continuous professional development to certified thoracic surgeons. It is likely that recertification will become an obligation during the coming decade. At its inception, the platform differentiated two different events. A 6-day course emphasizing on theoretic knowledge was created in Antalya in 2007. The same year, a 2-day school oriented to practical issues with hands-on in the animal lab was launched in Antalya. These two teaching tracks need further development. In the knowledge track, we intend to organize highly specialized 2-day courses to deepen insight into theoretical questions. The skill track will be implemented by specialized courses for high technology such as tracheal surgery, ECMO, robotics or chest wall reconstruction. In order to promote tomorrows' leadership, we created an academic competence track giving an insight into medical communication, methodology and management.

Full Text Available Angle Class II malocclusion associated with anterior open bite in adult patients demands a carefully elaborated orthodontic planning, aiming at restoring not only harmonious dental and facial esthetics, but also a balanced masticatory function. Orthognathic surgery or permanent teeth extraction are often the choice of treatment, therefore, treatment decision is related to all dental, skeletal and functional aspects. The present report discusses orthodontic compensation carried out by means of upper premolar extraction performed to correct the Class II canine relationship and, consequently, the anterior open bite, accepting that the upper incisors be retroclined. This clinical case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO as part of the requirements for obtaining the BBO Certification.

Abstract Introduction Obesity during pregnancy is associated with meta‐inflammation and an increased likelihood of clinical complications. Surgery results in intense, acute inflammatory responses in any individual. Because obese individuals exhibit constitutive inflammatory responses and high rates of Caesarian section, it is important to understand the impact of surgery in such populations. Whether more pronounced pro‐inflammatory cytokine responses and/or counterbalancing changes in anti‐inflammatory immune modulators occurs is unknown. Here we investigated innate immune capacity in vivo and in vitro in non‐obese, term‐pregnant controls versus healthy, term‐pregnant obese women (Class II, BMI 35–40). Methods Systemic in vivo induction of eleven pro‐ and anti‐inflammatory biomarkers and acute phase proteins was assessed in plasma immediately prior to and again following Caesarian section surgery. Independently, innate immune capacity was examined by stimulating freshly isolated PBMC in vitro with a panel of defined PRR‐ligands for TLR4, TLR8, TLR3, and RLR 24 h post‐surgery. Results The kinetics and magnitude of the in vivo inflammatory responses examined were indistinguishable in the two populations across the broad range of biomarkers examined, despite the fact that obese women had higher baseline inflammatory status. Deliberate in vitro stimulation with a range of PRR ligands also elicited pro‐ and anti‐inflammatory cytokine responses that were indistinguishable between control and obese mothers. Conclusions Acute in vivo innate immune responses to C‐section, as well as subsequent in vitro stimulation with a panel of microbial mimics, are not detectably altered in Class II obese women. The data argue that while Class II obesity is undesirable, it has minimal impact on the in vivo inflammatory response, or innate immunomodulatory capacity, in women selecting C‐section.

Previous studies have shown that preincisional epidural morphine, bupivacaine, and ketamine combined with epidural anesthesia (EA) and general anesthesia (GA) provided pre-emptive analgesia for upper abdominal surgery. Recent studies reported that ultralow-dose naloxone enhanced the antinociceptive effect of morphine in rats. This study investigated the benefits of preincisional and postoperative epidural morphine + ropivacaine + ketamine + naloxone (M + R + K + N) treatment for achieving postoperative pain relief in upper abdominal surgery. Eighty American Society of Anesthesiology I-II patients scheduled for major upper abdominal surgery were allocated to four groups in a randomized, single-blinded study. All patients received combined GA and EA with a continuous epidural infusion of 2% lidocaine (6-8 mL/h) 30 minutes after pain regimen. After GA induction, in Group I, an epidural pain control regimen (total 10 mL) was administered using 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg; M + R); in Group II, 1% lidocaine 8 (mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg; M + R + K); in Group III, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + naloxone (2 μg; M + R + N); and in Group IV, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg) + naloxone (2 μg; M + R + K + N), respectively. All patients received patient-controlled epidural analgesia (PCEA) with different pain regimens to control subsequent postoperative pain for 3 days following surgery. During the 3-day period following surgery, PCEA consumption (mL), numerical rating scale (NRS) score while cough/moving, and analgesic-related adverse effects were recorded. Total PCEA consumption for the 3-day observation period was 161.5±17.8 mL, 103.2±21.7 mL, 152.4±25.6 mL, and 74.1±16.9 mL for Groups I, II, III, and IV, respectively.

Dexmedetomidine infusion during middle ear surgery under general anaesthesia to provide oligaemic surgical field: A prospective study

Directory of Open Access Journals (Sweden)

Kumkum Gupta

2015-01-01

Full Text Available Background and Aims: Middle ear surgery requires bloodless surgical field for better operating conditions, deep level of anaesthesia and rapid emergence. Recent studies suggest that α2 agonists could provide desired surgical field, sedation and analgesia. The present study was aimed to evaluate the clinical effects of dexmedetomidine infusion as anaesthetic adjuvant during middle ear surgery using operating microscope. Methods: Sixty four adult patients aged 18-58 years, American Society of Anaesthesiologists Grades I and II, of both gender were randomised into two comparable equal groups of 32 patients each for middle ear surgery under general anaesthesia with standard anaesthetic technique. After induction of general anaesthesia, patients of Group I were given dexmedetomidine infusion of 0.5 μg/kg/h and patients of Group II were given placebo infusion of normal saline. Isoflurane concentration was titrated to achieve a systolic blood pressure 30% below the baseline value. All patients were assessed intra-operatively for bleeding at surgical field, haemodynamic changes, awakening time and post-operative recovery. Results: Statistically significant reduction was observed in the required percentage of isoflurane (0.8 ± 0.6% to maintain the systolic blood pressure 30% below the baseline values in patients receiving dexmedetomidine infusion when compared to those receiving placebo infusion (1.6 ± 0.7%. Patients receiving dexmedetomidine infusion had statistically significant lesser bleeding at surgical field (P < 0.05. The mean awakening time and recovery from anaesthesia did not show any significant difference between the groups. Conclusion: Dexmedetomidine infusion can be safely used to provide oligaemic surgical field for better visualization using operating microscope for middle ear surgery.

Postoperative wound infection also called as surgical site infection (SSI), is a trouble some complication of lumbar spine surgeries and they can be associated with serious morbidities, mortalities and increase resource utilization. With the improvement in diagnostic modalities, proper surgical techniques, antibiotic therapy and postoperative care, infectious complications can result in various compromises afterwards. The objective was to study the relation of surgical site infection in clean lumbar surgeries with the doses of antibiotics. This Retrospective study was conducted at Shifa International Hospital, from January 2006 to March 2008. Methods: Hundred post operated cases of lumber disc prolapse, lumbar stenosis or both studied retrospectively by tracing their operated data from hospital record section for the development of surgical site infection (SSI). The patients were divided into three groups depending upon whether they received single, three or more than three doses of antibiotics respectively. Complete data analyses and cross tabulation done with SPSS version 16. Result: Of 100 cases, only 6% had superficial surgical site infection; only 1 case with co morbidity of hypertension was detected. Twenty-one cases had single dose of antibiotic (Group-I), 59 cases had 3 doses (Group-II) and 20 cases received multiple doses (Group-III). There was no infection in Group-I. Only one patient in Group-II and 5 patients in Group-III developed superficial SSI. While 4 in Group-II, 3 in Group-III, and none of Group-I had >6 days length of stay (LOS). Conclusion The dose of antibiotic directly correlates with the surgical site infection in clean lumbar surgeries. When compared with multiple doses of antibiotics a single preoperative shot of antibiotic is equally effective for patients with SSI. (author)

The study objective was to determine the effects of implementing a blood conservation algorithm on blood product use and outcomes in a community cardiac surgery program. A blood management strategy including lower hemoglobin transfusion threshold and algorithm-driven decisions was adopted. Intraoperatively, point-of-care testing was used to avoid inappropriate component transfusion. A low prime perfusion circuit was adopted. Blood was withdrawn from patients before initiating bypass when possible. Patients undergoing coronary and valve procedures were included. Outlier patients receiving more than 10 units packed red blood cells were excluded. Data were collected for 6 months as a baseline group (group I). A 3-month period of program implementation was allotted. Data were subsequently collected for 6 months and comprised the study patients (group II). Prospective data were collected on demographics, blood use, and outcomes. Group I comprised 481 patients, and group II comprised 551 patients. Group II received fewer units of packed red blood cells, fresh-frozen plasma, and cryoprecipitate than group I. There was no difference in platelets transfused. Total blood product use was reduced by 40% in group II (P conservation algorithm can be rapidly introduced, leading to reductions in blood and component use with no detrimental effect on early outcomes. Point-of-care testing can direct component transfusion in coagulopathic cases, with most coagulopathic patients requiring platelets. Further research will determine the effects of reduced transfusions on long-term outcomes. Copyright © 2012 The American Association for Thoracic Surgery. Published by Mosby, Inc.

Background People with atrial fibrillation (AF) often undergo cardiac surgery for other underlying reasons and are frequently offered concomitant AF surgery to reduce the frequency of short- and long-term AF and improve short- and long-term outcomes. Objectives To assess the effects of concomitant AF surgery among people with AF who are undergoing cardiac surgery on short-term and long-term (12 months or greater) health-related outcomes, health-related quality of life, and costs. Search methods Starting from the year when the first “maze” AF surgery was reported (1987), we searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library (March 2016), MEDLINE Ovid (March 2016), Embase Ovid (March 2016), Web of Science (March 2016), the Database of Abstracts of Reviews of Effects (DARE, April 2015), and Health Technology Assessment Database (HTA, March 2016). We searched trial registers in April 2016. We used no language restrictions. Selection criteria We included randomised controlled trials evaluating the effect of any concomitant AF surgery compared with no AF surgery among adults with preoperative AF, regardless of symptoms, who were undergoing cardiac surgery for another indication. Data collection and analysis Two review authors independently selected studies and extracted data. We evaluated the risk of bias using the Cochrane ‘Risk of bias’ tool. We included outcome data on all-cause and cardiovascular-specific mortality, freedom from atrial fibrillation, flutter, or tachycardia off antiarrhythmic medications, as measured by patient electrocardiographic monitoring greater than three months after the procedure, procedural safety, 30-day rehospitalisation, need for post-discharge direct current cardioversion, health-related quality of life, and direct costs. We calculated risk ratios (RR) for dichotomous data with 95% confidence intervals (CI) using a fixed-effect model when heterogeneity was low (I2 ≤ 50%) and random

Obesity is associated with greater rates of surgical complications. To address these complications after outpatient plastic surgery, obese patients may seek care in the emergency department and potentially require admission to the hospital, which could result in greater health care charges. The purpose of this study was to determine the relationship of obesity, postdischarge hospital-based acute care, and hospital charges within 30 days of outpatient plastic surgery. From state ambulatory surgery center databases in four states, all discharges for adult patients who underwent liposuction, abdominoplasty, breast reduction, and blepharoplasty were identified. Patients were grouped by the presence or absence of obesity. Multivariable regression models were used to compare the frequency of hospital-based acute care, serious adverse events, and hospital charges within 30 days between groups while controlling for confounding variables. The final sample included 47,741 discharges, with 2052 of these discharges (4.3 percent) being obese. Obese patients more frequently had a hospital-based acute care encounter [7.3 percent versus 3.9 percent; adjusted OR, 1.35 (95% CI,1.13 to 1.61)] or serious adverse event [3.2 percent versus 0.9 percent; adjusted OR, 1.73 (95% CI, 1.30 to 2.29)] within 30 days of surgery. Obese patients had adjusted hospital charges that were, on average, $3917, $7412, and $7059 greater (p Obese patients who undergo common outpatient plastic surgery procedures incur substantially greater health care charges, in part attributable to more frequent adverse events and hospital-based health care within 30 days of surgery.

Purpose: Radiotherapy (RT) planning for breast cancer using lung density correction improves dose homogeneity. Its use obviates the need for a medial wedge, thus reducing scatter to the opposite breast. Although lung density correction is used at many centers in planning for early-stage breast cancer, long-term results of local control and survival have not been reported. Since 1984, we have used lung density correction for dose calculations at the University of Michigan. We now present our 10-year and 15-year results. Methods and Materials: The records of 867 patients with Stage I/II breast cancer treated with breast-conserving surgery and RT with or without systemic therapy were reviewed. Tangential fields delivering 45-50 Gy to the whole breast calculated using lung density correction were used. A boost was added in 96.8% of patients for a total median dose of 61.8 Gy. Results: With a median follow-up of 6.6 years (range, 0.2-18.9 years), 5-, 10-, and 15-year actuarial rates of in-breast tumor recurrence as only first failure were 2.2%, 3.6%, and 5.4%, respectively. With surgical salvage, the 15-year cumulative rate of local control was 99.7%. Factors that significantly predicted for increased rate of local recurrence in multivariate analysis were age ≤ 35 years, hazard ratio 4.8 (95% confidence interval [CI], 1.6-13.9) p = 0.004; negative progesterone receptor status, hazard ratio 6.8 (95% CI, 2.3-20.3) p = < 0.001; negative estrogen receptor status, hazard ratio 4.0 (95% CI, 1.5-11.1) p = 0.007; and lack of adjuvant tamoxifen therapy, hazard ratio 7.7 (95% CI, 1.7-33.3) p = 0.008. Relapse-free survival rates at 5, 10, and 15 years were 84.6%, 70.8%, and 55.9%, respectively; breast cancer-specific survival rates were 94.4%, 90.5%, and 86.9%, respectively; and corresponding estimates for overall survival were 89.7%, 75.7%, and 61.3%. Conclusions: Use of lung density correction was associated with high rates of local control, relapse-free survival, breast

Vitamin D deficiency is common among obese patients presenting for bariatric surgery in Europe and North America. The prevalence of vitamin D deficiency in this patient population in Lebanon and the Middle East has not been studied. The aim of this study was to determine the rate of vitamin D deficiency in a cohort of patients presenting for bariatric surgery in Lebanon. American University of Beirut Medical Center, Beirut, Lebanon. Data was extracted from a prospective database of patients presenting for bariatric surgery at the American University of Beirut Medical Center from July 2011 until June 2014. The prevalence of vitamin D deficiency was determined using established cut-offs followed by analysis of the relationship between low vitamin D and certain patient characteristics. More than two thirds of all patients (68.9%) were vitamin D deficient (≤19.9 ng/mL), whereas 22.6% had insufficient levels (20-29.9 ng/mL) and only 8.6 % had sufficient levels (≥30 ng/mL). Vitamin D levels were inversely associated with BMI>50 kg/m(2). Low vitamin D levels were also correlated with younger age, male gender, lack of physical exercise, and nonsunny season. No association was shown between 25-hydroxyvitamin D deficiency and type 2 diabetes mellitus, cardiovascular disease, osteoarticular disease, hypertension, or depression. Vitamin D deficiency is prevalent among patients with Class II or Class III obesity presenting for bariatric surgery in Lebanon. These findings emphasize the need for careful attention when evaluating patients before bariatric surgery and the importance of providing patients with adequate supplementation.

Metoidioplasty presents one of the variants of phalloplasty in female transsexuals. Urethral lengthening is the most difficult part in this surgery and poses many challenges. We evaluated 207 patients who underwent metoidioplasty, aiming to compare two different surgical techniques of urethral lengthening, postoperative results, and complications. The study encompassed a total of 207 patients, aged from 18 to 62 years, who underwent single stage metoidioplasty between September 2002 and July 2011. The procedure included lengthening and straightening of the clitoris, urethral reconstruction, and scrotoplasty with implantation of testicular prostheses. Buccal mucosa graft was used in all cases for dorsal urethral plate formation and joined with one of the two different flaps: I-longitudinal dorsal clitoral skin flap (49 patients) and II-labia minora flap (158 patients). Results were analyzed using Z-test to evaluate the statistical difference between the two approaches. Also, postoperative questionnaire was used, which included questions on functioning and esthetical appearance of participating subjects as well as overall satisfaction. The median follow-up was 39 months (ranged 12-116 months). The total length of reconstructed urethra was measured during surgery in both groups. It ranged from 9.1 to 12.3 cm (median 9.5) in group I and from 9.4 to 14.2 cm (median 10.8) in group II. Voiding while standing was significantly better in group II (93%) than in group I (87.82%) (P lengthening confirmed combined buccal mucosa graft and labia minora flap as a method of choice for urethroplasty in metoidioplasty, minimizing postoperative complications. © 2013 International Society for Sexual Medicine.

Full Text Available Background:Postoperative pain is an important surgical problem. Recent studies in pain pathophysiology have led to the hypothesis that with perioperative administration of analgesics (pre-emptive analgesia it may be possible to prevent or reduce postoperative pain. This study was planned to investigate the efficacy of pre-emptive analgesia on postoperative pain after major gynecologic abdominal surgeries. Methods: In this prospective, double-blinded, randomized, and placebocontrolled trial, 60 ASA physical status I and II patients undergoing major abdominal gynecologic surgeries were randomized to receive 45 mL of bupivacaine 0.375% or 45mL of normal saline; 30 mL and 15 mL of the treatment solution was administered into the peritoneal cavity and incision, respectively, before wound closure. The pain score of the patients was evaluated by the visual analogue scale (VAS on awakening, and at 6, 12, and 24h after surgery. Time to first analgesia request and total analgesic requirements in the first 24h were recorded. Results: Pain scores were significantly higher in the placebo group than in the bupivacaine group on awakening (5.98±1.01 v.s 1.05±1.05; p<0.001, and at 6h after surgery (5.37±0.85 vs. 2.51±1.02; p<0.001. First request to analgesia was significantly longer in the bupivacaine patients than in the placebo group (5.87±3.04 h vs.1.35±0.36; p<0.001.Meperidine consumption over 24h was 96.00 ±17.53 mg in the placebo group compared with 23.28 ±14.89 mg in the bupivacaine patients (p<0.001.Conclusion:A combination of intraperitoneal and incisional bupivacaine infiltration at the end of abdominal gynecologic surgeries reduces postoperative pain on awakening and for 6 hours after surgery, and provides significant opioidsparing analgesia for 24 h after gynecologic abdominal surgeries.

Surgery has been regarded as the standard treatment for patients with non-small cell lung cancer in the early stage, while radiotherapy has become an effective alternative for medically inoperable patients and those who refuse surgery. We reviewed the records of 31 patients with stage I-II non-small cell lung cancer treated by radiotherapy between 1980 and 1997. There were 15 patients in stage I and 16 in stage II. The variables analyzed for influence on cause-specific survival and loco-regional control were: age, performance status, clinical stage, tumor size, tumor site, radiation field, radiation dose, and combination with chemotherapy. The overall and cause-specific 1-, 2-, 3-, and 5-years survival rates were 71% and 77%; 63% and 73%; 34% and 48%; and 17% and 32%, respectively. Five-year survival rate for patients with peripheral tumor in the lung was 72%, with 70% loco-regional control, while the 5-year survival rate of patients whose tumor originated in the central region was 20%, with 25% loco-regional control. These differences had marginal significance on univariate analysis (P=0.07), but only tumor site (central vs peripheral) showed marginal significant influence on cause-specific survival (P=0.08) and loco-regional control (P=0.07) on multivariate analysis. There were no fatal complications, including radiation-induced myelopathy. The present series showed satisfactory results with definitive radiotherapy for patients with medically inoperable stage I-II non-small cell lung cancer, with results similar to those in recent reports of radiotherapy. The only significant variable was that patients with peripheral tumors had a better prognosis than patients with central tumors. (author)

RESULTS: One hundred nineteen patients were enrolled (mean age: 41.23+11.30 years, with a predominance of the female gender (83.2%, non-Caucasian race (55%, married individuals or in a stable union (65.5%, with a high school education (40.3%and active in the job market (37%. Weight and body mass index (BMI were 128.77+25.28Kg and 49.09+9.26Kg/m2,respectively in the preoperative period (class II obesity and 87.19+19.16Kg and 33.04+6.21Kg/m2, respectively in the postoperative period (class I obesity (p<0.001. Hypertension was the most frequent disease in the pre (66.6% and postoperative (36.5% periods. The prevalence of alcohol use was 26.6% in the preoperative period, of which 2.2% of high risk, and 35.1% in the postoperative period, of which 1.4% of probable dependence; this difference did not achieve statistical significance (p=0.337. CONCLUSION: The prevalence of abusive alcohol intake and/or probable dependence was low in both the pre and postoperative periods, with little evidence of risky consumption among the patients submitted to bariatric surgery.

Cataract and glaucoma are leading causes of blindness worldwide, and their co-existence is common in elderly people. Glaucoma surgery can accelerate cataract progression, and performing both surgeries may increase the rate of postoperative complications and compromise the success of either surgery. However, cataract surgery may independently lower intraocular pressure (IOP), which may allow for greater IOP control among patients with co-existing cataract and glaucoma. The decision between undergoing combined glaucoma and cataract surgery versus cataract surgery alone is complex. Therefore, it is important to compare the effectiveness of these two interventions to aid clinicians and patients in choosing the better treatment approach. To assess the relative effectiveness and safety of combined surgery versus cataract surgery (phacoemulsification) alone for co-existing cataract and glaucoma. The secondary objectives include cost analyses for different surgical techniques for co-existing cataract and glaucoma. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 10), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2014), EMBASE (January 1980 to October 2014), PubMed (January 1948 to October 2014), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to October 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en).

The scope of general surgery practice has evolved tremendously in the last 20 years. However, clinical experience in general surgery residency training has undergone relatively little change. To evaluate the current scope of academic general surgery and its implications on surgical residency. The University HealthSystem Consortium and Association of American Medical Colleges established the Faculty Practice Solution Center (FPSC) to characterize physician productivity. The FPSC is a benchmarking tool for academic medical centers created from revenue data collected from more than 90,000 physicians who practice at 95 institutions across the United States. The FPSC database was queried to evaluate the annual mean procedure frequency per surgeon (PFS) in each calendar year from 2006 through 2011. The associated work relative value units (wRVUs) were also examined to measure physician effort and skill. During the 6-year period, 146 distinct Current Procedural Terminology codes were among the top 100 procedures, and 16 of these procedures ranked in the top 10 procedures in at least 1 year. The top 10 procedures accounted for more than half (range, 52.5%-57.2%) of the total 100 PFS evaluated for each year. Laparoscopic Roux-en-Y gastric bypass was consistently among the top 10 procedures in each year (PFS, 18.2-24.6). The other most frequently performed procedures included laparoscopic cholecystectomy (PFS, 30.3-43.5), upper gastrointestinal tract endoscopy (PFS, 26.5-34.3), mastectomy (PFS, 16.5-35.0), inguinal hernia repair (PFS, 15.5-22.1), and abdominal wall hernia repair (PFS, 21.6-26.1). In all years, laparoscopic Roux-en-Y gastric bypass generated the highest number of wRVUs (wRVUs, 491.0-618.2), and laparoscopic cholecystectomy was regularly the next highest (wRVUs, 335.8-498.7). A significant proportion of academic general surgery is composed of bariatric surgery, yet surgical training does not sufficiently emphasize the necessary exposure to technical expertise

Paitients and methods: We retrospectively reviewed a database of 188 patients who underwent resection for colorectal cancer with laparoscopic surgery between July 2007 and March 2015. The prognostic nutrition index(PNI), modified Glas- gow prognostic score(mGPS), controlling nutritional status(CONUT), and neutrophil/lymphocyte ratio(N/L)were measured in these patients. We examined the association between postoperative complications and clinicopathological factors. The study included 110 men and 78 women. Median age was 68 years. The site of the primary lesion was colon in 118 and rectum in 70 patients. Postoperative complications higher than Grade II(Clavien-Dindo classification)were reported in 24(12.8%)patients: Surgical site infection(SSI)in 12, remote infection in 7, ileus in 5, and others in 2 patients. Clinicopathological factors related to complications were rectal surgery, large amount of intraoperative bleeding, and long operative time. The related immunologic and nutritional factors were mGPS 2, PNI below 40, and N/L above 3. CONUT was not associated with complications in ourcases. mGPS, PNI, and N/L are predictive factors for complications in laparoscopic colorectal surgery.

2018-01-01

Background Postoperative pressure ulcers are important indicators of perioperative care quality, and are serious and expensive complications during critical care. This study aimed to identify perioperative risk factors for postoperative pressure ulcers. Methods This retrospective case-control study evaluated 2,498 patients who underwent major surgery. Forty-three patients developed postoperative pressure ulcers and were matched to 86 control patients based on age, sex, surgery, and comorbidities. Results The pressure ulcer group had lower baseline hemoglobin and albumin levels, compared to the control group. The pressure ulcer group also had higher values for lactate levels, blood loss, and number of packed red blood cell (pRBC) units. Univariate analysis revealed that pressure ulcer development was associated with preoperative hemoglobin levels, albumin levels, lactate levels, intraoperative blood loss, number of pRBC units, Acute Physiologic and Chronic Health Evaluation II score, Braden scale score, postoperative ventilator care, and patient restraint. In the multiple logistic regression analysis, only preoperative low albumin levels (odds ratio [OR]: 0.21, 95% CI: 0.05–0.82; P pressure ulcer development. A receiver operating characteristic curve was used to assess the predictive power of the logistic regression model, and the area under the curve was 0.88 (95% CI: 0.79–0.97; P pressure ulcer development after surgery.

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

The findings at preoperative nephroanigiography of 42 hypertensive patients with unilateral renal artery stenosis or occlusion were correlated with the blood pressure response following surgery and also with the preoperative renal vein renin activity ratio. A stenosis reducing luminal area by at least 90 per cent (or occlusion) and the presence of collateral circulation are considered to be highly suggestive of renovascular hypertension.

Simplified Model Surgery Technique for Segmental Maxillary Surgeries

Directory of Open Access Journals (Sweden)

Namit Nagar

2011-01-01

Full Text Available Model surgery is the dental cast version of cephalometric prediction of surgical results. Patients having vertical maxillary excess with prognathism invariably require Lefort I osteotomy with maxillary segmentation and maxillary first premolar extractions during surgery. Traditionally, model surgeries in these cases have been done by sawing the model through the first premolar interproximal area and removing that segment. This clinical innovation employed the use of X-ray film strips as separators in maxillary first premolar interproximal area. The method advocated is a time-saving procedure where no special clinical or laboratory tools, such as plaster saw (with accompanying plaster dust, were required and reusable separators were made from old and discarded X-ray films.

Surgical outcomes of patients with chronic lymphocytic leukemia (CLL) undergoing cardiac surgery are limited. Our objectives were to investigate hospital morbidity and mortality after open cardiac surgery in CLL versus non-CLL patients. From May 1995 to May 2015, 157 patients with CLL and 55,917 without and older than 47 years underwent elective cardiac surgery at Cleveland Clinic. By Rai criteria, 79 CLL patients (56%) were low risk (class 0), 13 (9.1%) intermediate risk (classes I and II), and 38 (27%) high risk (classes III and IV); 12 (8.5%) were in remission. Mean age of CLL patients was 72 ± 9.0 years, and 18% were women. CLL patients were propensity-score matched to 3 non-CLL patients to compare surgical outcomes. High-risk CLL patients received more blood products than matched non-CLL patients (33/38 [87%] versus 74/114 [65%], p = 0.01), but were less likely to receive cryoprecipitate (0% versus 15/114 [13%], p = .02). Intermediate-risk CLL patients received more platelet units, mean 12 versus 4.6 (p = 0.008). Occurrence of deep sternal wound infection (0% versus 5/471 [1.1%]), septicemia (5/157 [3.2%] versus 14/471 [3.0%]), and hospital mortality (4/157 [2.5%] versus 14/471 [3.0%]) were similar (p > 0.3), independent of prior chemotherapy treatment for CLL. Although CLL patients did not have higher hospital mortality than non-CLL patients, high-risk CLL patients were more likely to receive blood products. Risks associated with transfusion should be considered when evaluating CLL patients for elective cardiac surgery. Appropriate preoperative management, such as blood product transfusions, and alternative treatment options that decrease blood loss, should be considered for high-risk patients.

Full Text Available Background Today, with improvements in laparoscopy technique, surgery of rectal cancer is performed by laparoscopy. Objectives This study was performed to evaluate oncologic results of open versus laparoscopic surgery of rectal cancer in terms of resection margins, removal of lymph nodes and recurrence rate. Patients and Methods This descriptive-analytic study was performed on 88 patients with middle and lower rectal cancer in the two equivalent groups of laparoscopic and open surgery in Mashhad Ghaem and Omid hospitals during 2011 - 2013. Information including age, sex, number of removed and involved lymph nodes, proximal, distal, and radial margins, tumor stage and location, recurrence and disease-free survival collected in the questionnaire and analyzed using descriptive statistics and frequency distribution tables and t-test. Results Both groups of open and laparoscopic surgery had similar characteristics of age, sex, recurrence and disease-free survival, tumor margins and one-year mortality. The number of removed and involved lymph nodes was higher in the laparoscopic group (5.16 vs. 3.55, respectively, with P < 0.050, and 1.74 vs. 0.59 with P = 0.023, but the ratio of involved lymph nodes to the total number of removed lymph nodes was not different between the two groups (LNR (P = 0.071. Tumor stage was higher in the laparoscopic group and most were in stages II and III (P < 0.001. Conclusions Laparoscopic surgery is an effective technique for safe margin and removing lymph nodes in rectal cancer.

Platelet-rich plasma (PRP) in dental and oral surgery: from the wound healing to bone regeneration.

Platelet-rich plasma (PRP) is a new approach to tissue regeneration and it is becoming a valuable adjunct to promote healing in many procedures in dental and oral surgery, especially in aging patients. PRP derives from the centrifugation of the patient's own blood and it contains growth factors that influence wound healing, thereby playing an important role in tissue repairing mechanisms. The use of PRP in surgical practice could have beneficial outcomes, reducing bleeding and enhancing soft tissue healing and bone regeneration. Studies conducted on humans have yielded promising results regarding the application of PRP to many dental and oral surgical procedures (i.e. tooth extractions, periodontal surgery, implant surgery). The use of PRP has also been proposed in the management of bisphosphonate-related osteonecrosis of the jaw (BRONJ) with the aim of enhancing wound healing and bone maturation. The aims of this narrative review are: i) to describe the different uses of PRP in dental surgery (tooth extractions and periodontal surgery) and oral surgery (soft tissues and bone tissue surgery, implant surgery and BRONJ surgery); and ii) to discuss its efficacy, efficiency and risk/benefit ratio. This review suggests that the use of PRP in the alveolar socket after tooth extractions is certainly capable of improving soft tissue healing and positively influencing bone regeneration but the latter effect seems to decrease a few days after the extraction. PRP has produced better results in periodontal therapy in association with other materials than when it is used alone. Promising results have also been obtained in implant surgery, when PRP was used in isolation as a coating material. The combination of necrotic bone curettage and PRP application seem to be encouraging for the treatment of refractory BRONJ, as it has proven successful outcomes with minimal invasivity. Since PRP is free from potential risks for patients, not difficult to obtain and use, it can be employed

Full text: Introduction: The focal cortical dysplasias (FCD) are a main cause of drug-resistant epilepsies. The MRI appearance of FCD is specific but some FCD remain hidden for the MRI. Aim: The aim of this study was to investigate the success rate of epilepsy surgery in patients with FCD and especially MRI-negative FCD during the first 6 years of the epilepsy surgery program of University Hospital 'St. Ivan Rilski', Sofia. Material and methods: Fourteen patients with drug resistant epilepsy and focal cortical dysplasias were operated on from January 2006 to april 2012. The mean age at surgery was 13 years (7-35 years) and the mean age of epilepsy onset was 7 years (1 year - 19 years). The presurgical work-up have included preoperative MRI (1.5T, GE) and seizures registration with video- EEG in all patients, PET-CT in 4 patients and invasive EEG in 5 patients. Eleven patients have MRI-positive cortical dysplasia and 3 patients were MRI negative. Results: Complete seizure control (Engel class I) was achieved in 9 patients, significant improvement (Engel class II) was observed in 3 patients and two patients remain without improvement (Engel class IV). In the small group of 3 patients with MRI-negative FCD, complete seizure control was achieved in two patients. No significant improvement was observed in one patient with MRI-negative FCD and one patient with MRI-positive FCD. Discussion: FCD type I are frequently invisible for the MRI and the localization of the epileptogenic zone is a difficult problem. Many studies have demonstrated the negative predictive value of MRI-negative FCD regarding seizure control after epilepsy surgery for drug-resistant epilepsy. Conclusions: Patients with drug-resistant epilepsy and MRI-negative FCD are good candidates for epilepsy surgery but need comprehensive presurgical workup including PET-CT and invasive-EEG.

Full Text Available Background: Deep brain stimulation (DBS surgery is an established therapeutic option for alleviating movement disorders. It represents unique challenges for anaesthesiologists. We retrospectively reviewed the patients, who underwent this surgery at our institution, to study anaesthetic management and perioperative complications. Materials and Methods: After taking approval from the Institutional Ethics Committee, medical, surgical and anaesthesia records of 67 patients who were admitted to undergo DBS surgery during 11 years period (January 2001 to December 2011 were retrieved and reviewed. Sixty-five patients underwent the procedure. Various anaesthetic events and perioperative complications were noted and appropriate statistical analysis was carried out to analyse the data. Results: Electrode placement under monitored anaesthesia care (MAC was the most commonly used technique (86% of patients. Intra-operative complications occurred in 16 patients (24% whereas post-operative complication occurred in 10 patients (15.4%. There was one mortality. Though age >60 years and American Society of Anesthesiologists status > II were found to be the risk factors for post-operative complications in the bivariate analysis; they were not significant in multivariate analysis. Conclusions: We report our experience of DBS surgery, which was performed using MAC in majority of patients, though general anaesthesia is also feasible. Further prospective randomised studies comprising large number of patients are warranted to corroborate our finding and to find out the most suitable sedative agent.

International Nuclear Information System (INIS)

Rossi, Luis Antonio; Bromberg, Sansom Henrique

2005-01-01

Postoperative pleural-pulmonary changes (PPC) are very common following elective abdominal surgery, resolving without clinical manifestations in most patients. The incidence and risk factors associated are unknown. Objective: to determine the incidence of PPC and possible association with risk factors using computerized tomography (CT). Material and method: thirty seven patients submitted to elective abdominal surgery were prospectively analyzed using CT performed in the preoperative period and 48 hours after surgery. The PPC was scored from 0 to III. The risk factors evaluated were: age, sex, obesity, smoking history, alcoholism, comorbid conditions, cancer, ASA classification, duration of surgery, surgical incision type and number of days of hospitalization. Results: Pleura effusion was detected by CT in 70.3% (26/37) of the patients and pulmonary atelectasis in 75.5% (28/37). Grade I and II PPC was found in 59.5% (22/37) of the patients and grade III in 21.6% (8/37). Two (5.4%) of these patients developed serious pulmonary complications whereas one patient died. Surgery due to cancer, class ASA >2, longitudinal incision and > 15 cm showed statistical significance and were associated with pleural effusion. The hospitalization was over 2.4 longer for patients with PPC. Conclusion: PPC is frequently seen in patients submitted to abdominal surgery. The use of the CT for the detection of pulmonary atelectasis and pleural effusion proved to be effective. Most cases of PPC are self-limited, resolving without symptoms. (author)

Bariatric surgery makes up an increasing percentage of general surgery training. The safety of resident involvement in these complex cases has been questioned. We evaluated patient outcomes in resident performed laparoscopic bariatric procedures. Retrospective review of patients undergoing a laparoscopic bariatric procedure over seven years at a tertiary care single center. Procedures were primarily performed by a general surgery resident and proctored by an attending surgeon. Primary outcomes included operative volume, operative time and leak rate with perioperative outcomes evaluated as secondary outcomes. A total of 1649 bariatric procedures were evaluated. Operations included laparoscopic bypass (690) and laparoscopic sleeve gastrectomy (959). Average operating time was 136 min. Eighteen leaks (0.67%) were identified. Graduating residents performed an average of 89 laparoscopic bariatric cases during their training. There were no significant differences between resident levels with concern to operative time or leak rate (p 0.97 and p = 0.54). General surgery residents can safely perform laparoscopic bariatric surgery. When proctored by a staff surgeon, a resident's level of training does not significantly impact leak rate.

To present descriptive epidemiology of cataract surgery among Medicare recipients in the United States. Cataract surgery performed on Medicare beneficiaries in 2003 and 2004. Medicare claims data were used to identify all cataract surgery claims for procedures performed in the United States in 2003-2004. Standard assumptions were used to limit the claims to actual cataract surgery procedures performed. Summary statistics were created to determine the number of procedures performed for each outcome of interest: cataract surgery rates by age, sex, race and state; surgical volume by facility type and surgeon characteristics; time interval between first- and second-eye cataract surgery. The national cataract surgery rate for 2003-2004 was 61.8 per 1000 Medicare beneficiary person-years. The rate was significantly higher for females and for those aged 75-84 years. After adjustment for age and sex, blacks had approximately a 30% lower rate of surgery than whites. While only 5% of cataract surgeons performed more than 500 cataract surgeries annually, these surgeons performed 26% of the total cataract surgeries. Increasing surgical volume was found to be highly correlated with use of ambulatory surgical centers and reduced time interval between first- and second-eye surgery in the same patient. The epidemiology of cataract surgery in the United States Medicare population documents substantial variation in surgical rates by race, sex, age, and by certain provider characteristics.

We conducted a phase II clinical trial of induction chemotherapy followed by surgery ± radiotherapy for squamous cell carcinoma of the oral tongue (SCCOT) in young adults. From September 2001 to October 2004, 23 patients aged 18 to 49 years with clinical T2-3 N0-2 M0 SCCOT and no prior radiotherapy, chemotherapy, or neck dissection underwent induction chemotherapy (paclitaxel, ifosfamide, and carboplatin) followed by glossectomy and neck dissection ± radiotherapy and chemotherapy. On final surgical pathology, 9 patients (39%) had a complete/major (2 complete) histologic response at the primary tumor site; 8 patients (35%) had no response or progression. Similarly, 9 patients (39%) had a complete response in the neck or remained node negative; 6 patients (26%) had an increase in nodal category. No treatment-associated deaths occurred, and toxicity was modest. At a median follow-up from the end of treatment of 52 months (minimum, 23 months), 10 patients (43%) developed recurrence, and all 10 died of cancer. Crude recurrence/cancer death rates were associated with ≤ a partial response at the tongue (p = .029), poor histologic differentiation (p = .012), and multiple adverse features on final surgical pathology (p = .040). Response rates and overall survival with this induction chemotherapy regimen were limited, but complete/major response at the tongue was associated with excellent prognosis. Additionally, improved patient selection and predictive tumor biomarkers will be needed for induction chemotherapy to be routinely incorporated into the treatment of oral tongue cancer in young adults.

2016-01-01

Full Text Available Background: Cancelation of surgery is a constant agonizing dilemma for nearly all healthcare services that has been intensively investigated to find out its roots, consequences, and possible solutions. The rates of cancelation of surgery vary between centers and more so among surgical specialties with numerous reasons standing behind this phenomenon. Patients and Methods: In the current study, analysis of monthly cancelation rates from January 2009 to December 2012, and assessment of establishing new operating rooms (ORs using statistical process control charts was conducted. A detailed review of a total of 1813 cases canceled on the day of surgery from January to December 2012, to examine the various reasons of cancelation among surgical specialties. Results: The average cancelation rate was 11.1%, which dropped to 9.0% after launching of new theaters. Four reasons explained about 80% of cancelations; Patients "no show" was the leading cause of cancelation (27%. One-fourth of cancelations (24.3% were due to the need for further optimization, and the third most prominent cause of cancelation was a lack of OR time (19.5%. Unavailability of staff/equipment/implants accounted for only 0.7% of cancelations. The "no show" was the most common cause of cancelation among all surgical specialties ranging from 21% for plastic surgery to 32% in ophthalmic surgeries. Conclusion: It was confirmed that there is a unique profile of cancelation of surgery problem for every institute, an extension of infrastructure may not be the only solution. Control charts helped to enhance the general picture and are functional in monitoring and evaluating changes in the cancelation of surgery.

Full Text Available Review Objective: To review the recent developments and published literature on laparoendoscopic single-site (LESS surgery in gynaecology. Recent Findings: Minimally invasive surgery has become a standard of care for the treatment of many benign and malignant gynaecological conditions. Recent advances in conventional laparoscopy and robotic-assisted surgery have favorably impacted the entire spectrum of gynaecological surgery. With the goal of improving morbidity and cosmesis, continued efforts towards refinement of laparoscopic techniques have lead to minimization of size and number of ports required for these procedures. LESS surgery is a recently proposed surgical term used to describe various techniques that aim at performing laparoscopic surgery through a single, small-skin incision concealed within the umbilicus. In the last 5 years, there has been a surge in the developments in surgical technology and techniques for LESS surgery, which have resulted in a significant increase in utilisation of LESS across many surgical subspecialties. Recently published outcomes data demonstrate feasibility, safety and reproducibility for LESS in gynaecology. The contemporary LESS literature, extent of gynaecological procedures utilising these techniques and limitations of current technology will be reviewed in this manuscript. Conclusions: LESS surgery represents the newest frontier in minimally invasive surgery. Comparative data and prospective trials are necessary in order to determine the clinical impact of LESS in treatment of gynaecological conditions.

The adsorption of Pb(II), Cu(II), Cd(II), Zn(II), Ni(II), Fe(II) and As(V) onto bacterially produced metal sulfide (BPMS) material was investigated using a batch equilibrium method. It was found that the sulfide material had adsorptive properties comparable with those of other adsorbents with respect to the specific uptake of a range of metals and, the levels to which dissolved metal concentrations in solution can be reduced. The percentage of adsorption increased with increasing pH and adsorbent dose, but decreased with increasing initial dissolved metal concentration. The pH of the solution was the most important parameter controlling adsorption of Cd(II), Cu(II), Fe(II), Ni(II), Pb(II), Zn(II), and As(V) by BPMS. The adsorption data were successfully modeled using the Langmuir adsorption isotherm. Desorption experiments showed that the reversibility of adsorption was low, suggesting high-affinity adsorption governed by chemisorption. The mechanism of adsorption for the divalent metals was thought to be the formation of strong, inner-sphere complexes involving surface hydroxyl groups. However, the mechanism for the adsorption of As(V) by BPMS appears to be distinct from that of surface hydroxyl exchange. These results have important implications to the management of metal sulfide sludge produced by bacterial sulfate reduction.

Full Text Available Aim: In this study we compared the clinical outcomes of the patients who underwent steroid injection and the ones who received additional local adjuvant therapy (cauterization alcohol following open surgery. Material and Method: The retrospective study included 73 patients who were diagnosed with unicameral bone cyst and underwent steroid injection or open surgery between 1995 and 2011. The patients comprised 23 (31.5% females and 50 (68.5% males, with a mean age of 9 (6-18 years and mean follow-up period of 4.71 (2-9 years. Open surgery was performed in 49 and steroid injection in 24 patients. In the open surgery group, local adjuvant treatment was added subsequently. In this group, healing was viewed radiologically. The patients were analyzed in three groups depending on the rate of the filling of the cystic area with a new bone: (I complete healing, (II residual healing, and (III inadequate healing. Results: In the steroid injection group, complete healing was observed in 5 (20.8%, residual healing in 13 (54.1%, and complete failure in 6 (25% patients. Average healing time was 32 (13-45 months. In the open surgery group, complete healing occurred in 24 (48.9%, residual healing in 20 (40.8%, and complete failure in 5 (10.2% patients. Average healing time was 15 (10-29 months. Discussion: Steroid Injection is a practical and minimally-invasive method, yet it leads to a lower success rate when compared to open surgery combined with local adjuvant therapy.

For hardly any other organ can the development of medicine and technical advances in the last 150 years be so clearly illustrated as for the prostate. The history of radical prostatectomy was initially characterised by the problems in approaching this relatively difficulty accessible organ. In 1867, Theodor Billroth in Vienna performed the first partial prostatectomy via a perineal access. In 1904, Hugh Hampton Young and William Stewart Halsted at the Johns Hopkins Hospital in Baltimore / USA carried out the first successful extracapsular perineal prostatectomy and opened up a new era. In Germany, Prof. Friedrich Voelcker in Halle in 1924 developed the so-called ischiorectal prostatectomy. But it was left to Terence Millin to publish in 1945 the first series of retropubic prostatectomies. In 1952, the sacroperineal approach according to Thiermann and the sacral prostatectomy according to were introduced. Finally, in 1991 another new era in prostate surgery started with the first laparoscopic prostatectomy. This development peaked in 2011 with the presentation of the laparoscopic DaVinci prostatectomy by Binder. Originally a stepchild of urological surgery that was to be avoided whenever possible due to the fear of serious complications, the prostate has progressed in the course of time to an obscure object of lust. The stepchild has become the favorite child.

Vitreoretinal (VR) surgery is the third most common intraocular surgery after refractive and cataract surgery. The impact of statin therapy on VR surgery outcomes remains unclear, despite a potentially beneficial effect. We explored the association of preoperative statin therapy and the need for revitrectomy after primary vitrectomy. Our historical, population-based, register-based, VR surgery cohort consisted of 5709 patients operated in a tertiary, academic referral hospital in Finland, during 2008-2014, covering 6.5 years. Subgroup analysis was performed as follows: eyes operated due to (i) rhegmatogenous retinal detachment (RRD), (ii) VR interface diseases (macular pucker/hole), (iii) diabetic maculopathy or proliferative retinopathy, (iv) vitreous haemorrhage, (v) lens subluxation, (vi) vitreous opacities or (vii) other VR indication. The primary end-point event was revitrectomy during a postoperative follow-up period of 1 year due to retinal redetachment, vitreous rehaemorrhage, postoperative endophthalmitis, recurrent pucker or unclosed macular hole. Rhegmatogenous retinal detachment (RRD) was the second most frequent indication of VR surgery, including 1916 patients, with 305 re-operations with rate 0.20 (95% CI 0.18-0.23) per person-year. Statin treatment in time of operation was associated with lower risk of re-operation according to relative scale (incidence rate ratio 0.72, 95% CI 0.53-0.97), but not in absolute scale (incidence rate difference -0.58, 95% CI -4.30 to 3.15 for 100 person-years). No association with statin therapy and vitrectomy outcome was observed in the other VR subgroups. Use of statin treatment was associated with a 28% lower risk of revitrectomy in patients operated due to RRD. Further randomized clinical trials are highly warranted. © 2018 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Problem-based learning (PBL) has been implemented during the clinical years in a few medical schools. The purpose of this study is to determine whether PBL provides a better education than traditional methods. Students in the first and third rotations (n = 42) went through the traditional clerkship, which utilized Socratic teaching (SI), while students in the second and fourth rotations (n = 36) were taught by the PBL method. Two performance measures were used to assess clerkship effectiveness. One was a modified essay examination (MEE) administered as part of the departmental evaluation. The other was the NBME-II exam and its surgery subsection NBME-II-S. The MEE was designed to measure six dimensions of the problem-solving process. The NBME-II was utilized to measure knowledge. Unpaired t tests were used to identify statistically significant group differences. The PBL group performed significantly better on two MEE dimensions: (1) differential diagnosis formation (PBL, 92.5 +/- 0.8; SI, 89.1 +/- 0.5; P < 0.01) and (2) interpretation of clinical data (PBL, 93.3 +/- 0.6; SI, 91.6 +/- 0.4; P < 0.03). A third dimension, ordering appropriate lab and diagnostic studies, approached significance (P = 0.057), and the PBL group performed better. On the NBME-II there was not a significant difference between the two groups. However, the trend (P = 0.059) was for the PBL group to score higher on the NBME-II-S (PBL mean: 502 +/- 15; SI mean: 468 +/- 12). When overall achievement was controlled for, the PBL group performed significantly better than the SI group (P = 0.046) on the NBME-II-S.(ABSTRACT TRUNCATED AT 250 WORDS)

We reviewed results of the surgical outcome of pituitary tumors treated via the transsphenoidal approach between January, 1994 and January, 2010 at our institution. This data included 100 patients (124 procedures) treated through the sublabial transsphenoidal approach and 45 patients (54 procedures) treated through the endoscopic endonasal (bilateral nostrils) transsphenoidal approach performed by a single surgeon. The extent of tumor removal was significantly improved with endoscopic surgery; adjuvant gamma knife radiosurgery was needed for 65% of patients undergoing microsurgery vs. 30% for patients who had endoscopic surgery (p<0.0001). Patients who underwent endoscopic surgery had less intraoperative blood loss (mean volume: 100 mL for microsurgery patients vs. 30 mL for endoscopic surgery patients, p<0.0001), less pain, and less need for postoperative hormone replacement therapy (19% for microsurgery patients vs. 6% for endoscopic surgery patients; p<0.05). Cerebrospinal fluid (CSF) leakage and meningitis were experienced in one microsurgery patient (1%) and one endoscopic surgery patient (2.2%). Endoscopic surgery is a reasonable alternative to microsurgery and our experience supports the concept that an otolaryngologist/neurosurgeon team skilled in endoscopic techniques and pituitary surgery can safely make the transition from microsurgery to endoscopic surgery.

To describe the multi-channel cochlear implantation in patients with Waardenburg syndrome including surgeries, pre and postoperative hearing assessments as well as outcomes of speech recognition. Multi-channel cochlear implantation surgeries have been performed in 12 cases with Waardenburg syndrome type II in our department from 2000 to 2008. All the patients received multi-channel cochlear implantation through transmastoid facial recess approach. The postoperative outcomes of 12 cases were compared with 12 cases with no inner ear malformation as a control group. The electrodes were totally inserted into the cochlear successfully, there was no facial paralysis and cerebrospinal fluid leakage occurred after operation. The hearing threshold in this series were similar to that of the normal cochlear implantation. After more than half a year of speech rehabilitation, the abilities of speech discrimination and spoken language of all the patients were improved compared with that of preoperation. Multi-channel cochlear implantation could be performed in the cases with Waardenburg syndrome, preoperative hearing and images assessments should be done.

Tuberculosis (TB) is still a major public health concern, mostly affecting resource-constrained settings and marginalized populations. The fight against the disease is hindered by the growing emergence of drug-resistant forms whose management can be rather challenging. Surgery may play an important role to support diagnosis and treatment of the most complex cases and improve their therapeutic outcome. We conducted a non-systematic review of the literature based on relevant keywords through PubMed database. Papers in English and Russian were included. The search was focused on five main areas of intervention as follows: (I) diagnosis of complicated cases; (II) elimination of contagious persisting cavities, despite appropriate chemotherapy; (III) treatment of destroyed lung; (V) resection of tuberculomas; (VI) treatment of tuberculous pleural empyema. Although specific practical guidelines concerning surgical indications and approaches are currently unavailable, a summary of the evidence emerged from the scientific literature was elaborated to help the clinician in the management of severely compromised TB patients. The decision to proceed to surgery is usually individualized and a careful assessment of the patient’s risk profile is always recommended before performing any procedure in addition to appropriate chemotherapy.

Global experiences in general surgery suggest that previous abdominal surgery may negatively influence different aspects of perioperative care. As the incidence of bariatric procedures has recently increased, it is essential to assess such correlations in bariatric surgery. To assess whether previous abdominal surgery influences the course and outcomes of laparoscopic bariatric surgery. Seven referral bariatric centers in Poland. We conducted a retrospective analysis of 2413 patients; 1706 patients who underwent laparoscopic sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) matched the inclusion criteria. Patients with no history of abdominal surgery were included as group 1, while those who had undergone at least 1 abdominal surgery were included as group 2. Group 2 had a significantly prolonged median operation time for RYGB (P = .012), and the longest operation time was observed in patients who had previously undergone surgeries in both the upper and lower abdomen (P = .002). Such a correlation was not found in SG cases (P = .396). Groups 1 and 2 had similar rates of intraoperative adverse events and postoperative complications (P = .562 and P = .466, respectively). Group 2 had a longer median duration of hospitalization than group 1 (P = .034), while the readmission rate was similar between groups (P = .079). There was no significant difference between groups regarding the influence of the long-term effects of bariatric treatment on weight loss (percentage of follow-up was 55%). Previous abdominal surgery prolongs the operative time of RYGB and the duration of postoperative hospitalization, but does not affect the long-term outcomes of bariatric treatment.

Real-time vascular imaging that provides both anatomic and hemodynamic information could greatly facilitate the diagnosis of vascular diseases and provide accurate assessment of therapeutic effects. Here, we have developed a novel fluorescence-based all-optical method, named near-infrared II (NIR-II) fluorescence imaging, to image murine hindlimb vasculature and blood flow in an experimental model of peripheral arterial disease, by exploiting fluorescence in the NIR-II region (1000-1400 nm) of photon wavelengths. Because of the reduced photon scattering of NIR-II fluorescence compared with traditional NIR fluorescence imaging and thus much deeper penetration depth into the body, we demonstrated that the mouse hindlimb vasculature could be imaged with higher spatial resolution than in vivo microscopic computed tomography. Furthermore, imaging during 26 days revealed a significant increase in hindlimb microvascular density in response to experimentally induced ischemia within the first 8 days of the surgery (Pimaging make it a useful imaging tool for murine models of vascular disease. © 2014 American Heart Association, Inc.

Direct medical and non-medical costs incurred by those undergoing subsidised cataract surgery at Gusau eye clinic, Zamfara state, were recently determined. The aim of this study was to assess the willingness to pay for cataract surgery among adults with severe visual impairment or blindness from cataract in rural Zamfara and to compare this to actual costs. In three rural villages served by Gusau eye clinic, key informants helped identify 80 adults with bilateral severe visual impairment or blindness (pay for cataract surgery was determined. The proportion willing to pay actual costs of the (i) subsidised surgical fee (US$18.5), (ii) average non-medical expenses (US$25.2), and (iii) average total expenses (US$51.2) at Gusau eye clinic were calculated. Where participants would seek funds for surgery was determined. Among 80 participants (38% women), most (n = 73, 91%) were willing to pay something, ranging from pay US$18.5 (78% men), one-third (n = 26) were willing to pay US$25.2 (77% men); and 11% (n = 9) were willing to pay US$51.2 (all men). Only six participants (8%) already had the money to pay; one quarter (n = 20) would need to sell possessions to raise the funds. Willingness to pay for cataract surgery among adults with operable cataract in rural Zamfara state is far lower than current costs of undergoing surgery. People who were widowed-most of whom were women-were willing to pay least. Further financial support is required for cataract surgery to be universally accessible.

Nihilism: a benign denial.

Skandalakis, John E; Mirilas, Petros

2003-06-01

Nihilism is the belief that all possible knowledge on a given topic has been amassed and codified. Ranging from benign denial to deliberate attempts at excommunication, nihilism is often encountered in the history of medicine. Eustachius, Columbus, and Sylvius strongly criticized Vesalius and defended the authority of Galen. Riolan fervently rejected Harvey's monumental work on the circulation of blood. Gross stated that no honest and sensible surgeon would ever sanction thyroidectomy. Sandstrom's discovery of the parathyroids was met with silence. Transplantation of parathyroids by Mandl was not appreciated when announced. Aristotle's dictum that the heart cannot withstand serious injury led to Paget's statement that cardiac surgery had reached the limits set by nature, which no new techniques could overcome. The first Billroth I operation was welcomed as, "Hopefully, also the last." Pancreatic surgery was opposed because the organ was of no clinical interest and was impossible for surgeons to reach. Pancreatic transplantation was rejected for many years, despite good results. When Blundell used blood transfusion for postpartum hemorrhage, critics averred that his next exploit would be radical removal of the spleen. Bassini stated that it could be risky to publish more about radical treatment of inguinal hernias. Carcinomas of the lower sigmoid and upper rectum were deemed untreatable because of their inaccessibility. Colostomy during pediatric surgery was rejected many times. Although it is difficult for the human mind to move from a familiar point of view, this propensity should not infect science, thereby impeding advancement.

Full Text Available Complexes of Mn(II, Co(II, Ni(II, Pd(II and Pt(II were synthesized with the macrocyclic ligand, i.e., 2,3,9,10-tetraketo-1,4,8,11-tetraazacycoletradecane. The ligand was prepared by the [2 + 2] condensation of diethyloxalate and 1,3-diamino propane and characterized by elemental analysis, mass, IR and 1H NMR spectral studies. All the complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, IR, electronic and electron paramagnetic resonance spectral studies. The molar conductance measurements of Mn(II, Co(II and Ni(II complexes in DMF correspond to non electrolyte nature, whereas Pd(II and Pt(II complexes are 1:2 electrolyte. On the basis of spectral studies an octahedral geometry has been assigned for Mn(II, Co(II and Ni(II complexes, whereas square planar geometry assigned for Pd(II and Pt(II. In vitro the ligand and its metal complexes were evaluated against plant pathogenic fungi (Fusarium odum, Aspergillus niger and Rhizoctonia bataticola and some compounds found to be more active as commercially available fungicide like Chlorothalonil.

Resnick, Cory M; Kaban, Leonard B; Troulis, Maria J

2009-02-01

Minimally invasive surgery is defined as the discipline in which operative procedures are performed in novel ways to diminish the sequelae of standard surgical dissections. The goals of minimally invasive surgery are to reduce tissue trauma and to minimize bleeding, edema, and injury, thereby improving the rate and quality of healing. In orthognathic surgery, there are two minimally invasive techniques that can be used separately or in combination: (1) endoscopic exposure and (2) distraction osteogenesis. This article describes the historical developments of the fields of orthognathic surgery and minimally invasive surgery, as well as the integration of the two disciplines. Indications, techniques, and the most current outcome data for specific minimally invasive orthognathic surgical procedures are presented.

To evaluate the importance and benefits of using gases in vitreoretinal surgery. The gases represent a wide group of substances used in eye surgery for more than 100 years. The role of intraocular gases in vitreoretinal surgery is irreplaceable. Their use is still considered to be the "gold standard". An important step in eye surgery was the introduction of expanding gases--sulfur hexafluoride and perfluorocarbons into routine clinical practice. The most common indications for the use of intraocular gases are: retinal detachment, idiopathic macular hole, complications of vitreoretinal surgery and others. The introduction of intraocular gases into routine clinical practice, along with other modern surgical techniques resulted in significant improvement of postoperative outcomes in a wide range of eye diseases. Understanding the principles of intraocular gases use brings the benefits to the patient and physician as well. Due to their physical and chemical properties they pose far the best and most appropriate variant of intraocular tamponade. Gases also bring some disadvantages, such as difficulties in detailed fundus examination, visual acuity testing, ultrasonographic examination, difficulties in application of intravitreal drugs or reduced possibility of retina laser treatment. The gases significantly change optical system properties of the eye. The use of gases in vitreoretinal surgery has significantly increased success rate of retinal detachment surgery, complicated posterior segment cases, trauma, surgery of the macula and other diseases.

The treatment for the present case consisted of decompensation oflower incisors and extraction oftwo lower premolars, in order to obtain horizontal discrepancy allowing the surgery for mandibular advancement. At the end of treatment, we could clinically observe a Class I molar/canine relationship, normal overbite and overjet, presence of lip seal, type I facial profile with considerable aesthetic improvement. We can conclude that the ortho-surgical treatment is a therapeutic alternative providing the best prognosis in terms of aesthetic correction in patients with unpleasant facial profile.

Health-related quality of life (HRQOL) is an important outcome in pediatric epilepsy surgery, but there are few studies that utilize presurgical ratings to assess the effect of surgery on HRQOL. We collected parental ratings on the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire for 28 children who participated in neuropsychological assessment before and after epilepsy surgery. Our results revealed significant improvements in overall HRQOL after surgery, especially in physical and social activities. These changes were apparent despite generally unchanged intellectual and psychological functioning. Children with better seizure outcome had more improvement in HRQOL; however, improvements were not statistically different among children with Engel class I, II, and III outcomes. Our results suggest that children can experience significant improvements in HRQOL following epilepsy surgery even when neuropsychological functioning remains unchanged. Moreover, improvements in HRQOL appear evident in children who experience any worthwhile improvement in seizure control (Engel class III or better). Copyright © 2013 Elsevier Inc.

The impact of bariatric surgery beyond its effect on weight loss has entailed a change in the way of regarding it. The term metabolic surgery has become more popular to designate those interventions that aim at resolving diseases that have been traditionally considered as of exclusive medical management, such as type 2 diabetes mellitus (T2D). Recommendations for metabolic surgery have been largely addressed and discussed in worldwide meetings, but no definitive consensus has been reached yet. Rates of diabetes remission after metabolic surgery have been one of the most debated hot topics, with heterogeneity being a current concern. This review aims to identify and clarify controversies regarding metabolic surgery, by focusing on a critical analysis of T2D remission rates achieved with different bariatric procedures, and using different criteria for its definition. Indications for metabolic surgery for patients with T2D who are not morbidly obese are also discussed. Copyright © 2013 SEEN. Published by Elsevier Espana. All rights reserved.

Developments in robotic surgery have continued to advance care throughout the field of urology. The purpose of this review is to evaluate innovations in robotic surgery over the past 18 months. The release of the da Vinci Xi system heralded an improvement on the Si system with improved docking, the ability to further manipulate robotic arms without clashing, and an autofocus universal endoscope. Robotic simulation continues to evolve with improvements in simulation training design to include augmented reality in robotic surgical education. Robotic-assisted laparoendoscopic single-site surgery continues to evolve with improvements on technique that allow for tackling previously complex pathologic surgical anatomy including urologic oncology and reconstruction. Last, innovations of new surgical platforms with robotic systems to improve surgeon ergonomics and efficiency in ureteral and renal surgery are being applied in the clinical setting. Urologic surgery continues to be at the forefront of the revolution of robotic surgery with advancements in not only existing technology but also creation of entirely novel surgical systems.

To evaluate the impact of obesity on the outcomes of surgical treatment for endometrial cancer in general and also comparing laparoscopic and open abdominal approach. Retrospective case-control study (Canadian Task Force classification II-1). Obstetrics and Gynecology Department, University of Insubria, Varese, Catholic University of the Sacred Heart, Rome, International School of Surgical Anatomy, Sacred Heart Hospital, Negrar, and Sant'Orsola-Malpighi Hospital, Bologna, Italy. Data of consecutive patients who underwent surgery for endometrial cancer in 4 centers were reviewed. Univariate and multivariable analyses were performed. Adjustment for potential selection bias in surgical approach was made using propensity score (PS) matching. Laparoscopic or open surgical treatment for endometrial cancer. A total of 1266 patients were included, including 764 in the laparoscopy group and 502 in the open surgery group. A total of 391 patients (30.9%) were obese, including 238 (18.8%) with class I obesity, 89 (7%) with class II obesity, and 64 (5.1%) with class III obesity. The total number of complications, risk of wound complications, and venous thromboembolic events were higher in obese women compared with nonobese women. Blood transfusions, incidence/severity of postoperative complications, and postoperative hospital stay were significantly higher in the open surgery group compared with the laparoscopy group, irrespective of obesity. These differences remained significant in both multivariable analysis and PS-matched analysis. The percentage of patients who received lymphadenectomy declined significantly in patients with BMI ≥40 in both the laparoscopy and open surgery groups. Conversions from the initially intended minimally invasive approach to open surgery were 1.1% to 2.2% for women with BMI obese women in the laparoscopic group. Laparoscopy for endometrial cancer retains its advantages over open surgery, even in obese patients. However, operating on obese
