A Comparative Study of Transvaginal Tape, Transobturator Tape Outside-in, and Transvaginal Tape-obturator Inside-out Surgical Procedures in the Treatment of Stress Urinary Incontinence

The aim of this work was to use the Urinary Distress Inventory (UDI-6) and Incontinence Impact Quality of Life (IIQ-7) questionnaires to compare 3 surgical techniques for stress urinary incontinence: the transvaginal tape (TVT) (105 women), the transobturator tape outside-in (TOT) (43 women), and the transvaginal tape-obturator inside-out (TVT-O) (54 women). There were no significant differences in frequent urination, urine leakage related to the feeling of urgency, urine leakage related to physical activity, or small amounts of urine leakage. TVT-operated women had a lower percentage of micturition difficulties compared with TOT women. TVT-O-operated women described slight discomfort in the genital area compared with the TVT technique, but this difference was not significant when compared with the TOT technique. When utilizing the UDI-6 and IIQ-7 scoring modifications before and after surgery, no difference among these 3 techniques is apparent.

Hypertension and intra-operative incidents : a multicentre study of 125000 surgical procedures in Swiss hospitals

Rapport de synthèse : Bien que les complications sévères de l'anesthésie soient actuellement rares, des informations contradictoires existent à propos du rôle et de l'importance de l'hypertension artérielle chronique sur la survenue de complications en cours d'anesthésie. En raison de la prévalence élevée de l'hypertension artérielle dans la population et du grand nombre d'anesthésies effectuées, il est important de clarifier cette relation. Le but de l'étude était d'évaluer si les personnes hypertendues étaient à risque accru de présenter des complications lors d'anesthésies à partir de données collectées de routine lors d'anesthésies usuelles réalisées en Suisse. Nous avons utilisé les données figurant dans le registre ADS (Anesthésie Données Suisse) correspondant à des anesthésies, générales ou locorégionales, réalisées pour chirurgie élective chez des adultes, entre 2000 et 2004 dans 24 hôpitaux suisses. L'attention était portée principalement sur les incidents cardio-vasculaires, mais les autres incidents relevés de routine ont aussi été évalués. La présence d'une hypertension artérielle chronique était définie par la présence d'un traitement antihypertenseur ou par l'anamnèse d'une hypertension artérielle, combinée à la mesure d'une pression artérielle élevée (systolique >160 mm Hg ou diastolique >100 mm Hg) lors de l'examen préopératoire de l'anesthésiste. Les incidents relevés en cours d'anesthésie ont été définis a priori et sont enregistrés de routine sur la feuille d'anesthésie et reportés dans une base de données centralisée. En raison de la structure des données, des analyses hiérarchiques ont été effectuées incluant des variables individuelles (niveau 1), liées aux groupes d'interventions chirurgicales (niveau 2) et à l'hôpital (niveau 3). Parmi les 124 939 interventions, 27 881 (22%) concernaient des patients connus pour une hypertension artérielle chronique. Au moins un incident est survenu dans 16,8% des interventions (95% Cl 16,6 -17,0%). Chez 7 549 patients, au moins un incident cardio- vasculaire est survenu, soit dans 6% des anesthésies (95% Cl 5.9-6.2%). Le rapport des cotes (odds ratio) moyen ajusté pour les incidents cardio-vasculaires chez les patients hypertendus était de 1.38 (95% Cl 1.27-1.49), indiquant une augmentation du risque chez les patients hypertendus. Cependant, l'hypertension n'était pas liée à un risque augmenté de survenue d'un autre incident. Les rapports de cotes ajustés de la survenue d'une complication cardiovasculaire en présence d'une hypertension artérielle variaient selon les hôpitaux entre 0.41 et 2.25. Ainsi, cette étude confirme la présence d'un risque accru de survenue d'une complication cardiovasculaire chez un patient hypertendu lors d'une anesthésie pour chirurgie élective. Il s'agissait le plus souvent d'une arythmie ou d'une perturbation hémodynamique. Cette augmentation du risque proche de 40% a aussi été trouvée dans une revue systématique avec méta-analyse. L'hétérogénéité des institutions -qui persiste même en tenant compte des ajustements pour le type d'intervention chirurgicale et des variables individuelles (case-mix) - suggère des différences de pratique de l'anesthésie selon l'hôpital.

Palliative surgical procedures to restore shoulder function in obstetric brachial palsy. Critical analysis of Narakas' series.

Dr. Narakas intended to study a series of 61 cases of shoulder sequelae of obstetric palsy. His vast experience would have enriched our clinical knowledge of this ailment. The authors carry on with that study to clarify his therapeutic approach and share the benefit of his experience.

HMG CoA reductase inhibitors (statins) for preventing acute kidney injury after surgical procedures requiring cardiac bypass.

BACKGROUND: Acute kidney injury (AKI) is common in patients undergoing cardiac surgery among whom it is associated with poor outcomes, prolonged hospital stays and increased mortality. Statin drugs can produce more than one effect independent of their lipid lowering effect, and may improve kidney injury through inhibition of postoperative inflammatory responses. OBJECTIVES: This review aimed to look at the evidence supporting the benefits of perioperative statins for AKI prevention in hospitalised adults after surgery who require cardiac bypass. The main objectives were to 1) determine whether use of statins was associated with preventing AKI development; 2) determine whether use of statins was associated with reductions in in-hospital mortality; 3) determine whether use of statins was associated with reduced need for RRT; and 4) determine any adverse effects associated with the use of statins. SEARCH METHODS: We searched the Cochrane Renal Group's Specialised Register to 13 January 2015 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA: Randomised controlled trials (RCTs) that compared administration of statin therapy with placebo or standard clinical care in adult patients undergoing surgery requiring cardiopulmonary bypass and reporting AKI, serum creatinine (SCr) or need for renal replacement therapy (RRT) as an outcome were eligible for inclusion. All forms and dosages of statins in conjunction with any duration of pre-operative therapy were considered for inclusion in this review. DATA COLLECTION AND ANALYSIS: All authors extracted data independently and assessments were cross-checked by a second author. Likewise, assessment of study risk of bias was initially conducted by one author and then by a second author to ensure accuracy. Disagreements were arbitrated among authors until consensus was reached. Authors from two of the included studies provided additional data surrounding post-operative SCr as well as need for RRT. Meta-analyses were used to assess the outcomes of AKI, SCr and mortality rate. Data for the outcomes of RRT and adverse effects were not pooled. Adverse effects taken into account were those reported by the authors of included studies. MAIN RESULTS: We included seven studies (662 participants) in this review. All except one study was assessed as being at high risk of bias. Three studies assessed atorvastatin, three assessed simvastatin and one investigated rosuvastatin. All studies collected data during the immediate perioperative period only; data collection to hospital discharge and postoperative biochemical data collection ranged from 24 hours to 7 days. Overall, pre-operative statin treatment was not associated with a reduction in postoperative AKI, need for RRT, or mortality. Only two studies (195 participants) reported postoperative SCr level. In those studies, patients allocated to receive statins had lower postoperative SCr concentrations compared with those allocated to no drug treatment/placebo (MD 21.2 µmol/L, 95% CI -31.1 to -11.1). Adverse effects were adequately reported in only one study; no difference was found between the statin group compared to placebo. AUTHORS' CONCLUSIONS: Analysis of currently available data did not suggest that preoperative statin use is associated with decreased incidence of AKI in adults after surgery who required cardiac bypass. Although a significant reduction in SCr was seen postoperatively in people treated with statins, this result was driven by results from a single study, where SCr was considered as a secondary outcome. The results of the meta-analysis should be interpreted with caution; few studies were included in subgroup analyses, and significant differences in methodology exist among the included studies. Large high quality RCTs are required to establish the safety and efficacy of statins to prevent AKI after cardiac surgery.

Hypertension and intra-operative incidents: a multicentre study of 125000 surgical procedures in Swiss hospitals

Background: It is debated whether chronic hypertension increases the risk of cardiovascular incidents during anaesthesia. Methods: We studied all elective surgical operations performed in adults under general or regional anaesthesia between 2000 and 2004, in 24 hospitals collecting computerised clinical data on all anaesthetia since 1996. The focus was on cardiovascular incidents, though other anaesthesia-related incidents were also evaluated. Results: Among 124 939 interventions, 27 881 (22%) were performed in hypertensive patients. At least one cardiovascular incident occurred in 7549 interventions (6% [95% CI 5.9-6.2%]). The average adjusted odds ratio of cardiovascular risk in patients with chronic hypertension was 1.38 (95% CI 1.27-1.49). However, across hospitals, adjusted odd ratios varied from 0.41 up to 2.25. Hypertension did not increase the risk of other incidents. Conclusions: Hypertensive patients are still at risk of intra-operative cardiovascular incidents. The heterogeneity of the risk to develop cardiovascular incidents varied across hospitals, despite taking into account casemix and hospital characteristics. These variations suggest that anaesthetic practices differ across anesthesia services

Are patients with non-invasive papillary thyroid carcinoma, follicular variant (niFV-PTC) and minimally invasive follicular thyroid carcinoma with capsular invasion only (miFTC-CIO) overtreated?An institutional experience

Background. Recently several meetings and position papers advocate a change in terminology regarding thyroid neoplasms with indolent behavior, proposing the term "tumor" instead of "carcinoma". This change concerns non-invasive papillary thyroid carcinoma, follicular variant (niFV-PTC) and minimally invasive follicular thyroid carcinoma with capsular invasion only (miFTC-CIO). The aim of our study was to evaluate the impact of considering niFV-PTC and miFTC-CIO as lesions of low malignant potential, and to see how this change would influence patient management at our institution. Methods. A 32 months retrospective review of all well differentiated thyroid carcinomas (WDTC) (papillary and follicular carcinomas) diagnosed at our institution was performed, excluding tumors of uncertain malignant potential as well as poorly differentiated and anaplastic carcinomas. We retrieved cases of niFV-PTC and miFTC-CIO, reviewed histological slides to confirm diagnosis and recorded patient treatment. Results. A total of 9 (7.3%) niFV-PTC (4 males and 5 females, aged between 30 and 68 years, mean: 50.8 years old) and 2 (1.6%) cases of miFTC-CIO (2 females, 31 and 51 years old) were identified out of 122 WDTC diagnosed in the study period. The initial treatment consisted in 5 lobectomies and 6 total thyroidectomies (3 because of a compressive goiter, 2 because of a fine-needle aspiration diagnosis of suspicious for papillary thyroid carcinoma and 1 because of a fine-needle aspiration diagnosis of papillary carcinoma). The treatment following the histological diagnosis consisted in 4 thyroidectomy completions among patients who underwent simple lobectomy (4/5, 80%) and 9/11 (82%) radioablations with I131. Conclusions. The incidence of niFV-PTC is low at our institution, probably because we apply strict diagnostic criteria for this lesion. Simple lobectomy with negative margins is the treatment of choice in cases diagnosed as niFV-PTC and miFTC-CIO, due to the indolent course of these neoplasms. All cases with thyroidectomy completions and radioablations could have been avoided. As a consequence, the change of such terminology heavily impacts the malignancy risk evaluated cytologically as well as patients' management.

Successful minimally invasive surgery for primary hyperparathyroidism: influence of preoperative imaging and intraoperative parathyroid hormone levels.

PURPOSE: Adenoma is the main parathyroid disorder leading to primary hyperparathyroidism (PHP). Minimally invasive parathyroidectomy (MIP) is recognized as a valid procedure for adenoma-related PHP. It requires precise preoperative localization combining Tc-99m-MIBI (methoxy-isobutyl-isonitrile) scintigraphy and single-photon emission computed tomography (SPECT) with x-ray computed tomography (CT) and intraoperative confirmation of successful excision by change in intact parathormone (iPTH) levels. The study aim was to assess the surgery success in relation to these two parameters. METHODS: All patients operated on for PHP from 2005 to mid-2014 at our institution were retrospectively reviewed. MIP was performed in case of precise preoperative adenoma localization on scintigraphy, absence of past cervical surgery, and absence of concomitant thyroid resection necessity. In these patients, iPTH levels were monitored intraoperatively. Confirmation criteria for iPTH values were a return to normal level or a decrease >50 % of basal iPTH level. RESULTS: There were 197 PHP operations during the study period: 118 MIP and 79 bilateral neck explorations (BNEs). The MIP success rate was 95 % (112/118) with a preoperative MIBI scan ± CT accurate in 94 % (111/118) of the patients and with correct iPTH in 90 % (106/118) of the cases. Among the 12 iPTH levels that did not meet the confirmation criteria, 10 returned to normal range by postoperative day 2. Treatment failure appeared in three patients (one BNE, two MIPs). CONCLUSIONS: Tc-99m-MIBI dual-phase scintigraphy with SPECT/CT is the key examination for functional and morphological parathyroid adenoma localization. If preoperative scintigraphy is obvious and intraoperative assessment is clear, one could possibly safely omit iPTH, as it may lead to unnecessary BNE in primary PHP.

Laparoscopic and open colorectal surgery in everyday practice : retrospective study

Résumé Introduction: La plupart des études disponibles sur la chirurgie colorectale par laparoscopie concernent des patients hautement sélectionnés. Le but de cette étude est d'analyser les résultats à court et à long terme de l'ensemble des patients traités dans un service de chirurgie générale. Méthodes: Il s'agit d'une analyse rétrospective d'un registre prospectif interne au service, dans lequel tous les patients consécutifs opérés pour la première fois du colon et du rectum entre mars 1993 et décembre 1997 ont été enregistrés. Les informations concernant le suivi ont été collectées par questionnaire. Résultats: Un total de 187 patients ont été opérés par laparoscopie et 215 patients par chirurgie ouverte durant la période d'étude. Les informations concernant le suivi ont pu être collectées dans 95% des cas avec une évolution de 1-107 mois (médiane 59 mois), respectivement de 1-104 mois (médiane 53 mois). Une conversion fut nécessaire dans 28 cas (15%) mais ceux-ci restent inclus dans le groupe laparoscopie pour l'analyse par intention de traitement. Dans le groupe laparoscopie, les opérations ont duré plus longtemps (205 vs 150 min, p<0.001) mais l'hospitalisation a été plus courte (8 vs 13 jours, p<0.001). La reprise du transit a été plus rapide après laparoscopie, mais uniquement après intervention sur le colon gauche (3 vs 4 jours, p<0.01). Cependant, la sélection préopératoire (nombre plus élevé d'urgences et de patients avec un risque anesthésiologique élevé dans le groupe de la chirurgie ouverte) a été favorable à la laparoscopie. Le taux de complications (global ainsi que pour chaque complication chirurgicale) a été similaire dans les deux groupes, avec un taux global de 20% environ. Conclusions: Malgré une sélection favorable des cas, uniquement très peu d'avantages à la laparoscopie sur la chirurgie ouverte ont pu être observés. Abstract Background: Most studies available on laparoscopic colorectal surgery focus on highly selected patient groups. The aim of the present study was to review short- and long-term outcome of everyday patients treated in a general surgery department. Methods: Retrospective review was carried out of a prospective database of all consecutive patients having undergone primary laparoscopic (LAP) or open colorectal surgery between March 1993 and December 1997. Follow-up data were completed via questionnaire. Results: A total of 187 patients underwent LAP resection and 215 patients underwent open surgery. Follow up was complete in 95% with a median of 59 months (range, 1-107 months) and 53 months (range, 1-104 months), respectively. There were 28 conversions (15%) in the LAP group and these remained in the LAP group in an intention-to-treat analysis. The LAP operations lasted significantly longer for all types of resections (205 vs 150 min, P<0.001) and hospital stay was shorter (8 vs 13 days, P<0.001). Recovery of intestinal function was faster in the LAP group, but only after left-sided procedures (3 vs 4days, P<0.01). However, preoperative patient selection (more emergency operations and patients with higher American Society of Anesthesiologists (ASA) score in the open group) had a major influence on these elements and favours the LAP group. Surprisingly, the overall surgical complication rate (including long-term complications such as wound hernia) was 20% in both groups with rates of individual complications also being comparable in both groups. Conclusion: Despite a patient selection favourable to the laparoscopy group, only little advantage in postoperative outcome could be shown for the minimally invasive over the open approach in the everyday patient.

Chirurgie [Surgery].

In 2012, an innovative approach for staged in situ liver transection was proposed that could allow for even more aggressive major hepatectomies. Otherwise, after 25 years, laparoscopy became "traditional" and other minimally invasive techniques continue to be developed but their indications deserve further investigation. Less aggressive treatment in non-complicated diverticulitis becomes more popular, and even antibiotic treatment has been challenged by a randomized study. In colorectal oncology, local resection or observation only seems to become a valuable approach in selected patients with complete response after neo adjuvant chemoradiation. Finally, enhanced recovery pathways (ERAS) have been validated and is increasingly accepted for colorectal surgery and ERAS principles are successfully applied in other surgical fields.

Chirurgie [Surgery].

The evolution of visceral surgery is characterized by defining with ever increasing precision the real role of new techniques. Hernia repair, abdominal compartment syndrome, pancreatic and colorectal cancers, as well as haemorrhoids, confirm this reality. Although laparoscopy has clear indications in hernia repairs, many still prefer open approach. The abdominal compartment syndrome, now better understood thanks to laparoscopy, is increasingly important in intensive care. The role of laparoscopy for pancreatic and colorectal cancers is still limited. The development of minimally invasive techniques has led to a reduced morbidity of surgery for haemorrhoids and better results. The economic impact of new technologies must remain a primary concern.

3D virtual rendering before laparoscopic partial splenectomy in children.

INTRODUCTION: Partial splenectomy in children is a good surgical option for hematological diseases and focal splenic tumors because it allows the preservation of the spleen's immunological function. Furthermore, it can be performed by laparoscopy in children as it is a safe procedure, offering the benefits of a minimally invasive approach. MATERIALS AND METHODS: The software VR-render LE version 0.81 is a system that enables the visualization of bidimentional 3D images with magnification of anatomical details. We have applied this system to five cases of non-parasitic splenic cysts before laparoscopic partial splenectomy. RESULTS: The images obtained with VR rendering software permitted the preoperative reconstruction of the vascularization of the splenic hilum, allowing the surgeon safe vessel control during laparoscopic procedures. All five partial splenectomies were carried out with no complications or major blood loss. CONCLUSIONS: Laparoscopic partial splenectomy should be a first choice procedure because it is feasible, reproducible, and safe for children; furthermore, it preserves enough splenic tissue thereby preventing post-splenectomy infections. Volume rendering provides high anatomical resolution and can be useful in guiding the surgical procedure.

Guidelines for perioperative care after radical cystectomy for bladder cancer: enhanced Recovery After Surgery (ERAS(®)) society recommendations.

PURPOSE: Enhanced recovery after surgery (ERAS) pathways have significantly reduced complications and length of hospital stay after colorectal procedures. This multimodal concept could probably be partially applied to major urological surgery. OBJECTIVES: The primary objective was to systematically assess the evidence of ERAS single items and protocols applied to cystectomy patients. The secondary objective was to address a grade of recommendation to each item, based on the evidence and, if lacking, on consensus opinion from our ERAS Society working group. EVIDENCE ACQUISITION: A systematic literature review was performed on ERAS for cystectomy by searching EMBASE and Medline. Relevant articles were selected and quality-assessed by two independent reviewers using the GRADE approach. If no study specific to cystectomy was available for any of the 22 given items, the authors evaluated whether colorectal guidelines could be extrapolated. EVIDENCE SYNTHESIS: Overall, 804 articles were retrieved from electronic databases. Fifteen articles were included in the present systematic review and 7 of 22 ERAS items were studied. Bowel preparation did not improve outcomes. Early nasogastric tube removal reduced morbidity, bowel recovery time and length of hospital stay. Doppler-guided fluid administration allowed for reduced morbidity. A quicker bowel recovery was observed with a multimodal prevention of ileus, including gum chewing, prevention of PONV and minimally invasive surgery. CONCLUSIONS: ERAS has not yet been widely implemented in urology and evidence for individual interventions is limited or unavailable. The experience in other surgical disciplines encourages the development of an ERAS protocol for cystectomy.

Traitement des varices et des télangiectasies [Treatment of varicose veins and telangiectasias].

Dermatologic surgery has evolved enormously within the past few years especially for the treatment of varicose veins and telangiectasias. New minimally-invasive techniques have been developed: lasers, echo-sclerosis, surgery with tumescent anesthesia and endovascular treatment of saphenous veins. Most interventions can be performed with local anesthesia in the office setting. These new treatments are intended to decrease the risks of surgery, reduce medical costs and the necessity for hospitalization, and improve functional and esthetic results.

Disc degeneration: current surgical options.

Chronic low back pain attributed to lumbar disc degeneration poses a serious challenge to physicians. Surgery may be indicated in selected cases following failure of appropriate conservative treatment. For decades, the only surgical option has been spinal fusion, but its results have been inconsistent. Some prospective trials show superiority over usual conservative measures while others fail to demonstrate its advantages. In an effort to improve results of fusion and to decrease the incidence of adjacent segment degeneration, total disc replacement techniques have been introduced and studied extensively. Short-term results have shown superiority over some fusion techniques. Mid-term results however tend to show that this approach yields results equivalent to those of spinal fusion. Nucleus replacement has gained some popularity initially, but evidence on its efficacy is scarce. Dynamic stabilisation, a technique involving less rigid implants than in spinal fusion and performed without the need for bone grafting, represents another surgical option. Evidence again is lacking on its superiority over other surgical strategies and conservative measures. Insertion of interspinous devices posteriorly, aiming at redistributing loads and relieving pain, has been used as an adjunct to disc removal surgery for disc herniation. To date however, there is no clear evidence on their efficacy. Minimally invasive intradiscal thermocoagulation techniques have also been tried, but evidence of their effectiveness is questioned. Surgery using novel biological solutions may be the future of discogenic pain treatment. Collaboration between clinicians and basic scientists in this multidisciplinary field will undoubtedly shape the future of treating symptomatic disc degeneration.

Prevention and management of potential adverse events during transapical aortic valve replacement.

BACKGROUND AND AIM OF THE STUDY: Transapical transcatheter aortic valve replacement (TAVR) is a new minimally invasive technique with a known risk of unexpected intra-procedural complications. Nevertheless, the clinical results are good and the limited amount of procedural adverse events confirms the usefulness of a synergistic surgical/anesthesiological management in case of unexpected emergencies. METHODS: A review was made of the authors' four-year database and other available literature to identify major and minor intra-procedural complications occurring during transapical TAVR procedures. All implants were performed under general anesthesia with a balloon-expandable Edwards Sapien stent-valve, and followed international guidelines on indications and techniques. RESULTS: Procedural success rates ranged between 94% and 100%. Life-threatening apical bleeding occurred very rarely (0-5%), and its incidence decreased after the first series of implants. Stent-valve embolization was also rare, with a global incidence ranging from 0-2%, with evidence of improvement after the learning curve. Rates of valve malpositioning ranged from 0% to < 3%, whereas the risk of coronary obstruction ranged from 0% to 3.5%. Aortic root rupture and dissection were dramatic events reported in 0-2% of transapical cases. Stent-valve malfunction was rarely reported (1-2%), whereas the valve-in-valve bailout procedure for malpositioning, malfunctioning or severe paravalvular leak was reported in about 1.0-3.5% of cases. Sudden hemodynamic management and bailout procedures such as valve-in-valve rescue or cannulation for cardiopulmonary bypass were more effective when planned during the preoperative phase. CONCLUSION: Despite attempts to avoid pitfalls, complications during transapical aortic valve procedures still occur. Preoperative strategic planning, including hemodynamic status management, alternative cannulation sites and bailout procedures, are highly recommended, particularly during the learning curve of this technique.
