Le reflux gastro-oesophagien: l'apport de l'endoscopie dans l'indication opératoire et les contrôles postopératoires [Gastroesophageal reflux: importance of endoscopy in surgical indications and postoperative control].

Endoscopy constitutes an important investigation in the presence of a gastro-oesophageal reflux. The primary intention is to exclude the possibility of an organic pathology, for example cancer, which has not been demonstrated by other investigative procedures. Accordingly it must provide a detailed exploration of the whole superior digestive tract, from the mouth to the duodenum. Secondly, endoscopy must establish the consequence of the reflux on the mucosa of the lower oesophagus both by a macroscopic and a detailed microscopic description. Peptic lesions are classified according to 4 degrees of severity. The difficulty in evaluating the very early lesions (1st degree) and the advanced stages (4th degree) necessitates systematic biopsies of the lesions. The erythroplasic type of carcinoma in situ can present the same endoscopic changes as a 1st degree peptic lesion, whereas the exclusion of an adenocarcinoma constitutes the major preoccupation at the time of endoscopy of a 4th degree oesophagitis.

Lésions traumatiques rachidiennes et indications au traitement chirurgical [Surgical indications in spinal trauma]

Surgical indications in spinal trauma remain a controversial topic. In general, unstable cervical injuries such as displaced odontoid fractures, burst fractures or tear drop fractures require surgical intervention. Thoracolumbar compression injuries without posterior wall involvement or significant kyphosis can be treated conservatively. Surgery is indicated in fractures-dislocations and burst fractures with significant canal narrowing and/or major kyphosis. The role of emergency decompression as well as that of steroids remain uncertain since no study to date has convincingly proven their efficacy.

Laryngotracheal reconstruction for pediatric glotto-subglottic stenosis.

BACKGROUND: The management of pediatric laryngotracheal stenosis (LTS) can be challenging, and laryngotracheal reconstruction (LTR) with cartilage interposition grafting remains the mainstay of surgical treatment for pediatric LTS in most experienced centers. The purpose of this study was to report the results of this procedure in a center where primary cricotracheal resection is frequently performed. METHODS: A retrospective chart review was performed on 45 patients who underwent LTR in our hospital between October 1997 and July 2012. Demographic characteristics and information on the preoperative status, stenosis, and operation were collected. Primary outcomes were measured as overall (ODR) and operation-specific (OSDR) decannulation rates and secondary outcomes as morbidity, mortality, and postoperative functional results. RESULTS: ODR and OSDR were 86.7% (39/45) and 66.7% (30/45), respectively. Re-stenosis was observed in 11/45 (24%) patients, all of whom were endoscopically or surgically treated. Revision surgery was performed in 10 patients, 6 for re-stenosis and 2 for peristomial tracheomalacia. Two children died of mucous obstruction of tracheostomy tube at 3 and 6 months postoperatively (4.4%). Respiratory, voice, and swallowing functions were excellent or good in 86, 75, and 84% of patients, respectively. CONCLUSIONS: LTR for pediatric LTS has high decannulation rates with acceptable morbidity and mortality in selected patients. Most LTR procedures were double-stage for lower grade subglottic stenoses associated with glottic involvement that required stenting. Careful preoperative evaluation and adequate surgical indications are extremely important to achieve high decannulation rates.

Chirurgie viscérale. Chirurgie thyroïdienne et parathyroïdienne: place de la chirurgie minimale invasive [Update in thyroid and parathyroid surgery: the role for minimally invasive surgery].

Thyroid and parathyroid surgery takes an important place in general surgery. Preservation of essential cervical structures and cosmetic of outcomes of cervical incisions are major concern. Several minimally invasive strategies have been developed recently but their acceptance in the surgical community is low. Their main advantages are focused tissue dissection and improved cosmetics. In this review, management and surgical indications of thyroid nodules and parathyroid adenomas are discussed. The various minimally invasive techniques are described and their current indications are reviewed.

Quand faut-il opérer une rupture de la coiffe des rotateurs [When to operate a rotator cuff tear?]

Rotator cuff disease is the most common pathology causing shoulder pain with an overall prevalence rate of 30%. There is a significant association between increasing age and the presence of rotator cuff tears. Spontaneous healing of clinically relevant tears has not been observed. Although satisfactory pain relief is possible without rotator cuff tendon healing, functional outcome is better for healed repairs. Operative treatment must be considered in the context of the reasonable expectations for success. Repairability and potential of surgically tendon construct to heal are important considerations in surgical indications. There is no difference of outcomes between the arthroscopic and the open techniques.

L'hépatectomie réglée. A propos de 18 cas opérés dans un hôpital périphérique [Standardized hepatectomy. 18 cases operated in a peripheral hospital]

Hepatectomy has long been a formidable surgical procedure because the risk of hemorrhage it can involve. With a better understanding of hepatic anatomy, left hepatectomy, right hepatectomy and segmental hepatic resections have been standardized. Between January 1989 and December 1992, 18 hepatectomies were performed on 16 patients in the Department of Surgery, General Hospital, La Chaux-de-Fonds, Switzerland. The mean age of the patients was 65. The surgical indications were: hepatic metastases 11 (61%); gallbladder or biliary duct neoplasm 4 (22%); hydatic cyst 3 (17%). 11 segmental resection, 3 left hepatectomies, 2 right hepatectomies, 2 pericystectomies were performed. Blood loss during these operations averaged 2800 ml. Surgical complications appeared in 6 cases (hemorrhage 1, postoperative effusion 4, sepsis 1). One patient died within 30 days (mortality 5%). Hepatectomy is nowadays a safe procedure. It can be performed in a general hospital with a trained surgical team and an efficient intensive care unit

Four-corner bone arthrodesis with dorsal rectangular plate: series and personal technique.

Controversy exists about the best method to achieve bone fusion in four-corner arthrodesis. Thirty-five patients who underwent this procedure by our technique were included in the study. Surgical indications were stage II-III SLAC wrist, stage II SNAC wrist and severe traumatic midcarpal joint injury. Mean follow-up was 4.6 years. Mean active flexion and extension were 34 degrees and 30 degrees respectively; grip strength recovery was 79%. Radiological consolidation was achieved in all cases. The mean DASH score was 23 and the postoperative pain improvement by visual analogue scale was statistically significant. Return to work was possible at 4 months for the average patient. Complications were a capitate fracture in one patient and the need for hardware removal in four cases. Four-corner bone wrist arthrodesis by dorsal rectangular plating achieves an acceptable preservation of range of motion with good pain relief, an excellent consolidation rate and minimal complications.

Percutaneous biopsy through the foramen ovale for parasellar lesions: surgical anatomy, method, and indications.

Knowledge of the pathological diagnosis before deciding the best strategy for treating parasellar lesions is of prime importance, due to the relative high morbidity and side-effects of open direct approaches to this region, known to be rich in important vasculo-nervous structures. When imaging is not evocative enough to ascertain an accurate pathological diagnosis, a percutaneous biopsy through the transjugal-transoval route (of Hartel) may be performed to guide the therapeutic decision.The chapter is based on the authors' experience in 50 patients who underwent the procedure over the ten past years. There was no mortality and only little (mostly transient) morbidity. Pathological diagnosis accuracy of the method revealed good, with a sensitivity of 0.83 and a specificity of 1.In the chapter the authors first recall the surgical anatomy background from personal laboratory dissections. They then describe the technical procedure, as well as the tissue harvesting method. Finally they define indications together with the decision-making process.Due to the constraint trajectory of the biopsy needle inserted through the Foramen Ovale, accessible lesions are only those located in the Meckel trigeminal Cave, the posterior sector of the cavernous sinus compartment, and the upper part of the petroclival region.The authors advise to perform this percutaneous biopsy method when imaging does not provide sufficient evidence of the pathological nature of the lesion, for therapeutic decision. Goal is to avoid unnecessary open surgery or radiosurgery, also inappropriate chemo-/radio-therapy.

Implications of Objective vs Subjective Delirium Assessment in Surgical Intensive Care Patients.

Background Delirium is an independent predictor of increased length of stay, mortality, and treatment costs in critical care patients. Its incidence may be underestimated or overestimated if delirium is assessed by using subjective clinical impression alone rather than an objective instrument. Objectives To determine frequency of discrepancies between subjective and objective delirium monitoring. Methods An observational cohort study was performed in a surgical-cardiosurgical 31-bed intensive care unit of a university hospital. Patients' delirium status was rated daily by bedside nurses on the basis of subjective individual clinical impressions and by medical students on the basis of scores on the objective Confusion Assessment Method for the Intensive Care Unit. Results Of 160 patients suitable for analysis, 38.8% (n = 62) had delirium according to objective criteria at some time during their stay in the intensive care unit. A total of 436 paired observations were analyzed. Delirium was diagnosed in 26.1% of observations (n = 114) with the objective method. This percentage included 6.4% (n = 28) in whom delirium was not recognized via subjective criteria. According to subjective criteria, delirium was present in 29.4% of paired observations (n = 128), including 9.6% (n = 42) with no objective indications of delirium. A total of 8 patients with no evidence of delirium according to the objective criteria were prescribed haloperidol and lorazepam because the subjective method indicated they had delirium. Conclusions Use of objective criteria helped detect delirium in more patients and also identified patients mistakenly thought to have delirium who actually did not meet objective criteria for diagnosis of the condition.

Cardiac perforation after surgical repair of pectus excavatum.

Five days after surgical repair of pectus excavatum, this 7-year-old boy had a right-sided Kirschner wire protruding beneath the skin. The wire was repositioned blindly. Severe congestive heart failure developed. Surgical exploration showed a pierced right atrium, a torn septal leaflet of the tricuspid valve and noncoronary aortic cusp, and a large traumatic ventricular septal defect. The outcome and the indications and possible complications of surgery are discussed.

Indicazioni e risultati della laparostomia retroperitoneale nel trattamento della pancreatite acuta necrotizzante infetta [Indications and results of retroperitoneal laparostomy in the treatment of infected acute necrotizing pancreatitis]

The aim of this study is to describe personal experience with retroperitoneal laparostomy in the management of infected acute necrotizing pancreatitis. The presence of an infected phlegmon requires surgical debridement and drainage. The surgical approach can be either an anterior laparotomy with irrigation and drainage (which can be either an open or closed laparotomy) or a posterior laparostomy. Three patients (2 men and 1 woman) presented with an unfavourable course of their acute necrotizing pancreatitis despite the administration of broad spectrum antibiotics. A posterior laparostomy with necrosectomy and drainage was performed. The postoperative course was slowly favorable in all 3 cases. Abdominal CT is the best modality for the detection and follow-up of pancreatic necrosis. CT-guided fine needle aspiration can detect superinfection of areas of necrosis. Posterior laparostomy presents several advantages compared to an anterior approach. There is no contamination of the peritoneal cavity; the integrity of the abdominal wall is respected. The necrosectomy is equally complete and the drainage is better as it is direct and posterior.

Development of appropriateness criteria for the surgical treatment of symptomatic lumbar degenerative spondylolisthesis (LDS).

PURPOSE: Spine surgery rates are increasing worldwide. Treatment failures are often attributed to poor patient selection and inappropriate treatment, but for many spinal disorders there is little consensus on the precise indications for surgery. With an aging population, more patients with lumbar degenerative spondylolisthesis (LDS) will present for surgery. The aim of this study was to develop criteria for the appropriateness of surgery in symptomatic LDS. METHODS: A systematic review was carried out to summarize the current level of evidence for the treatment of LDS. Clinical scenarios were generated comprising combinations of signs and symptoms in LDS and other relevant variables. Based on the systematic review and their own clinical experience, twelve multidisciplinary international experts rated each scenario on a 9-point scale (1 highly inappropriate, 9 highly appropriate) with respect to performing decompression only, fusion, and instrumented fusion. Surgery for each theoretical scenario was classified as appropriate, inappropriate, or uncertain based on the median ratings and disagreement in the ratings. RESULTS: 744 hypothetical scenarios were generated; overall, surgery (of some type) was rated appropriate in 27 %, uncertain in 41 % and inappropriate in 31 %. Frank panel disagreement was low (7 % scenarios). Face validity was shown by the logical relationship between each variable's subcategories and the appropriateness ratings, e.g., no/mild disability had a mean appropriateness rating of 2.3 ± 1.5, whereas the rating for moderate disability was 5.0 ± 1.6 and for severe disability, 6.6 ± 1.6. Similarly, the average rating for no/minimal neurological abnormality was 2.3 ± 1.5, increasing to 4.3 ± 2.4 for moderate and 5.9 ± 1.7 for severe abnormality. The three variables most likely (p < 0.0001) to be components of scenarios rated "appropriate" were: severe disability, no yellow flags, and severe neurological deficit. CONCLUSION: This is the first study to report criteria for determining candidacy for surgery in LDS developed by a multidisciplinary international panel using a validated method (RAM). The panel ratings followed logical clinical rationale, indicating good face validity. The work refines clinical classification and the phenotype of degenerative spondylolisthesis. The predictive validity of the criteria should be evaluated prospectively to examine whether patients treated "appropriately" have better clinical outcomes.

Sténose de l'artère rénale: indications pour une revascularisation [Atherosclerotic renal stenosis: indications for revascularisation]

La sténose de l'artère rénale (SAR) est souvent associée à une maladie athéromateuse diffuse et, en conséquence, à une morbidité et une mortalité cardiovasculaires accrues. Le nombre de revascularisations de l'artère rénale a considérablement augmenté ces dernières années. Mais les succès rapportés par cette procédure, par rapport à un traitement médical seul, semblent modestes tant sur le contrôle de la pression artérielle que sur la progression de l'insuffisance rénale. La mise en évidence d'une SAR ne représente pas systématiquement une indication à une revascularisation. Plusieurs critères doivent être pris en compte, dont la localisation de la sténose, son retentissement hémodynamique, la fonction rénale, la sévérité de l'hypertension artérielle et la facilité avec laquelle le traitement antihypertenseur parvient à normaliser la pression artérielle. Atherosclerotic renal artery stenosis is often associated with diffuse atherosclerotic disease and consequently an increased cardiovascular morbidity and mortality. Despite evidence of only moderate clinical benefit in comparison with medical treatment to control the blood pressure and to prevent renal failure, renal endovascular revascularisation has become more and more popular. The decision to treat an atherosclerotic renal stenosis by revascularisation should be taken only after a close examination of the hemodynamic impact of the stenosis, the renal function, the severity of hypertension and the quality of blood pressure control achieved by the medical treatment

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of the practice in a surgical ward

Introduction The benefit of stress ulcer prophylaxis (SUP) in noncriticallyill patients has not been proved. Over-prescription of SUP isnot devoided of risks (i.e. drug-drug interactions, adverse events).This prospective study aimed to evaluate the use of proton pumpinhibitors (PPIs) for SUP in a visceral surgery ward.Materials & Methods Data collection was performed prospectivelyduring a 8-week period on patients hospitalized in a visceral surgeryward (58 beds). Patients with a PPI prescription for the treatment ofulcers, gastroesophageal reflux disease, esophagitis or epigastralgiawere excluded as well as patients hospitalized twice during the studyperiod. The American Society of Health-System Pharmacists guidelineson SUP were used to assess the appropriateness of de novo PPIprescriptions.Results Among 255 patients in the study, 138 (54.1%) received aprophylaxis with PPI, of which 86 (62.3%) were de novo PPI prescriptions.93.5% of patients received esomeprazole (according to thehospital drug formulary) mainly orally at 40 mg qd. 79.1% of patientshad no risk factors for SUP. 17.9% and 3.0% had one and two riskfactors, respectively. 95% of the patients with PPI were not hospitalizedin the intensive care unit (ICU) before their stay in the visceralsurgery ward. At discharge, PPI therapy was continued in 34.2% ofpatients with a de novo PPI prescription.Discussion & Conclusion This study highlights the over-utilizationof PPIs in non-ICU patients and the inappropriate continuation of PPIprescriptions at discharge. The PPI dosage prescribed for prophylaxiswas probably too high compared with the data of the literature.Treatment recommendations for SUP are needed to restrict PPIuse for justified indications.

Pontages veineux in situ. Indications, technique et résultats. A propos d'une étude prospective de 26 cas consécutifs [In situ venous grafts. Indications, technique and results. Prospective study of 26 consecutive cases].

The in situ saphenous vein bypass has been introduced in our department since 1989. A total of 26 bypasses in 22 patients have been followed prospectively. Indications for revascularisation have been severe arterial insufficiency in 73% of the cases (stage III or IV). With the exception of one postoperative death (myocardial infarction), all the patients have recovered uneventfully, with a regression to stage I. No amputation has been necessary. Morbidity has been 30%, with mainly minor local complications. The primary patency rate is 83% at one year and 78% after 2 and 3 years, whereas the secondary patency rate is 91% at one year, and remains constant thereafter up to 3 years. Considering our results and those from the literature, we believe that the in situ technique is very valuable, especially for below-knee vascular reconstruction. Technical difficulties of the method are analysed.
