Anesthésie locale par tumescence [Tumescent local anesthesia].

Tumescent anesthesia is a local anesthesia produced by the infiltration of a large volume of very dilute anesthetic solution into the subcutaneous tissue. Many surgical procedures (liposuction, facelift, varicose vein surgery, etc.), which were previously performed under general or locoregional anesthesia, can now be achieved with local tumescent anesthesia. This type of anesthesia has many advantages: reduction of both anesthetic risks and surgical complications (bleeding, hematoma), prolonged anesthesia reducing the need for postoperative analgesia, and costs reduction because all these surgical procedures can be performed on an outpatient basis.

Ulnar nerve transposition at the elbow : local anesthesia should be preferred to general anesthesia

Après la compression du nerf médian au niveau du tunnel carpien, la compression du nerf ulnaire au niveau du coude est le deuxième syndrome compressif le plus fréquent des nerfs périphériques. La chirurgie des nerfs périphériques consiste dans une décompression nerveuse et est caractérisée par un suivi post¬opératoire parfois très douloureux avec des douleurs qui peuvent chroniciser si insuffisamment traitées. Le traitement chirurgical de décompression nerveuse se fait traditionnellement sous anesthésie générale ou régionale. Une analgésie post-opératoire plus efficace et durable avec moindre risque de chronicisation avait justifié ce choix jusqu'à ce jour. Grâce au développement de la chirurgie ambulatoire ces dernières années, un grand nombre d'interventions chirurgicales au niveau de la main sont effectués sous anesthésie locale. Au vu d'une meilleure connaissance de cette technique d'anesthésie, son rôle dans la chirurgie des nerfs périphériques a été remis en question. Alors que plusieurs études ont démontré que l'anesthésie locale est aussi efficace que l'anesthésie générale et régionale au sujet de la chirurgie du tunnel carpien, son utilisation pour la chirurgie du nerf ulnaire reste peu connue. La raison de l'hésitation à l'utilisation de l'anesthésie locale pour le traitement du tunnel ulnaire est due au fait que dans plus de la moitié des cas, une simple décompression n'est pas suffisante et qu'il est souvent nécessaire de transposer le nerf ulnaire devant l'épicondyle ulnaire. La seule publication disponible au sujet de l'utilisation de l'anesthésie locale dans le traitement du tunnel ulnaire considère comme irréalisable d'utiliser cette méthode dans le cas d'une transposition. Malgré cette mise en garde, nous avons, depuis plusieurs années, des excellents résultats avec la transposition du nerf ulnaire sous anesthésie locale. Avec le but d'objectiver notre expérience dans ce domaine nous avons souhaité analyser nos résultats de façon rétrospective avec particulière attention aux douleurs post-opératoires et à la satisfaction des patients. Les dossiers de cinquante patients Consécutifs (26F, 24M) opérés par le même chirurgien dans notre service de 2002 à 2012 ont été analysés rétrospectivement. Les critères suivants ont été récoltés: l'âge du patient, la profession, la main dominante, les détails des techniques opératoires utilisées, le type d'anesthésie, l'intensité du suivi ainsi que les complications, le niveau de douleur dans l'immédiat post-opératorie ainsi que à une année de l'intervention. Les patients ont été divisés en 4 groupes: les opérés sous anesthésie générale avec transposition du nerf (n=17) ou sans transposition (n=10) et les opérés sous anesthésie locale avec transposition (n=12) ou sans transposition (n=11). Au premier jour la douleur était comparable dans tous les groupes. A une semaine, elle était deux fois plus importante lorsque la transposition avait été réalisée sous anesthésie générale par rapport à si une anesthésie locale avait été effectuée (p=0.03). La satisfaction s'est révélée plus élevée mais non significative chez les patients opérés sous anesthésie locale. Ces derniers étaient significativement plus enclins à répéter la chirurgie comparé a ceux opérés sous anesthésie générale (p=0.04). En conclusion, les résultats de cette étude suggèrent que l'anesthésie locale est au moins autant efficace que l'anesthésie générale en termes de complications et de douleurs post-opératoires indépendamment du fait qu'une transposition nerveuse soit effectuée ou pas. Un meilleur contrôle des douleurs à une semaine post-opératoire a contribué à une haute satisfaction des patients de notre étude.

Ulnar Nerve Transposition at the Elbow under Local Anesthesia: A Patient Satisfaction Study.

Background Ulnar nerve decompression at the elbow traditionally requires regional or general anesthesia. We wished to assess the feasibility of performing ulnar nerve decompression and transposition at the elbow under local anesthesia. Methods We examined retrospectively the charts of 50 consecutive patients having undergone ulnar nerve entrapment surgery either under general or local anesthesia. Patients were asked to estimate pain on postoperative days 1 and 7 and satisfaction was assessed at 1 year. Results On day 1, pain was comparable among all groups. On day 7, pain scores were twice as high when transposition was performed under general anesthesia when compared with local anesthesia. Patient satisfaction was slightly increased in the local anesthesia group. These patients were significantly more willing to repeat the surgery. Conclusion Ulnar nerve decompression and transposition at the elbow can be performed under local anesthesia without added morbidity when compared with general anesthesia.

Surgical treatment of ingrown toenail without matricectomy.

BACKGROUND: Partial excision of the nail matrix (matricectomy) is generally considered necessary in the surgical treatment of ingrown toenail. Recurrences may occur, however, and poor cosmetic results are frequently observed. OBJECTIVE: The objective is to present a new surgical procedure for ingrown toenail with complete preservation of the nail matrix. METHODS: Twenty-three patients with ingrown toenail were included in this study. The surgical excision was performed 1 week after the completion of treatment of the initial infection. A large volume of soft tissue surrounding the nail plate was removed under local anesthesia. No matrix excision was performed. RESULTS: Short-term results were excellent. No recurrences or severe complications were observed during the minimum 12-months follow-up period. Cosmetic results were remarkable. CONCLUSIONS: Ingrown toenail results from the compression of the lateral nail folds on the nail plate. This study shows that ingrown toenail can be surgically treated without matricectomy. A large volume of soft tissue surrounding the nail plate should be removed to decompress the nail and reduce inflammation. Cosmetic results are excellent and superior to the classical Emmert plasty. Postoperative nail dystrophies and spicule formation are not observed. The main advantage of this surgical approach is the complete preservation of the anatomy and function of the nail to improve both therapeutic and cosmetic results.

Kératose précancéreuse palpébrale [Eyelid precancerous keratosis].

A 25-year-old-male patient had one keratinized tumor on the inferior right eyelid, first observed 5 months before. Its size had been increasing for the last three weeks. The visual function was normal. Clinical examination disclosed a papillomatous lesion on the cutaneous middle part of the eyelid. A surgical excision was performed under local anesthesia. The histopathological study found a papillomatous epidermal proliferation with both structural and cytological atypias, concluding with a precancerous keratosis of the eyelid.

Cicatrice hypertrophique de la conjonctive palpébrale ou chéloïde de la conjonctive tarsale. A propos d'une observation anatomo-clinique [Hypertrophic eyelid conjunctival scar. A tarsal keloid].

The clinicopathologic case of a 53-year-old female patient with an abnormal tumor growing on the mucous part of the superior right eyelid is reported. The patient was operated on for ten years ago and a whitish mass slowly developed on the conjunctival face of the eyelid disturbing the use of corneal lenses. It was hard, painless and had the shape of a flat mushroom. The removal was performed under local anesthesia and allowed us to resect a hard and fibrous lesion. Histopathology showed that the lesion was made of a fibrous tissue organized like a hypertrophic scar. Surgical treatment of chalazion is frequent and rarely gives rise to abnormal scarring.

Der akute anale Schmerz [Acute anal pain].

Acute anal pain is a common proctological problem. A detailed history together with the clinical examination are crucial for the diagnosis. An acute perianal vein thrombosis can be successfully excised within the first 72 hours. Acute anal fissures are best treated conservatively using stool regulation and topical medications reducing the sphincter spasm. A chronic anal fissure needs surgery. Perianal abscesses can very often be incised and drained in local anesthesia. Proctalgia fugax and the levator ani syndrome are exclusion diagnoses and are treated symptomatically.

Scar asymmetry after abdominoplasty: the unexpected role of seroma.

Achievement of symmetry remains one of the goals of cosmetic procedures. Interestingly, scar asymmetry after abdominoplasty has been rarely considered a complication. However, this can have a significant impact on patient and surgeon satisfaction. This study identifies silent seromas as a potential cause of scar asymmetry.Among abdominoplasty procedures in a university hospital institution over a 30 months' period (October 1, 2007 to April 1, 2010), we retrospectively identified 6 patients who developed abdominal scar asymmetry only 3 months postoperatively and without any early warning complications (hematoma, seroma, or infection). Clinical examination was completed by abdominal diagnostic ultrasonography. Seroma capsulectomy under local anesthesia was performed in all cases.In all patients clinically presenting late abdominal scar asymmetry, ultrasonography confirmed the presence of an encapsulated chronic seroma. Surgical capsulectomy under local anesthesia resulted in reestablishment of former symmetry and high patient satisfaction. No complications such as wound infection, dehiscence, hematoma, or recurrence of seroma were detected after revision surgery.In our experience, fibrous capsule due to chronic seromas resulted in abdominal scar deviation and asymmetry. Surgical capsulectomy followed by wearing of compressive garments resulted to be an effective treatment with pleasant aesthetic outcome and no seroma recurrence. Silent seromas should be considered as a possible etiologic factor of scar asymmetries appearing during late follow-up after abdominoplasty.

Impact of preoperative embolization of the left gastric artery on the rate of anastomotic leakage after esophageal resection

Objective: Impaired blood flow of the gastric tube represents a major cause of anastomotic leakage after esophageal resection. In order to improve local vascularisation, preoperative embolization (PE) of the left gastric artery has recently been proposed. The aimof this study was to assess our initial experience of this novel approach with a particular focus on anastomotic leakage.Methods: A consecutive series of 102 patients (81 male, 21 female, median age 64 years) underwent resection (82 Ivor-Lewis procedures, 9 transhiatal resections, 11 triple incisions) for esophageal malignancies at our institution from 2000 to 2009. Since 2004, PE was used selectively in 19 patients 21 days prior to elective esophagectomy. Selection criteria were normal gastric vascular anatomy, no pre-existing vascular disease, i.e. atheromatosis of the celiac trunk or superior mesenteric artery, and resectability of the tumor. PE was performed under local anesthesia on a dedicated system in a standard fashion. Following percutaneous transfemoral visceral angiography to identify gastric vascular anatomy, embolization was performed either with 5-F or with coaxial 3-F catheters and fibered metal coils. We analyzed retrospectively patient's data, operative data, and outcome from a prospective database.Results: The overall anastomotic leakage rate was 18・6% (19/102 patients); cervical anastomosis had a leak rate of 25% compared to intrathoracic anastomosis leak rate of 18・2%. While 17 of 83 patients without PE developed anastomotic leakage (20・5%), there were only 2 of 19 patients after PE revealing an anastomotic leakage (10・5%). Otherwise, patients with PE had no more other complications. There was only one PE-related complication (i.e. partial splenic necrosis).Mean hospital stay was 25 days versus 27 days for patients with PE and without PE, respectively. The mortality rate was 7・8% (8/102 patients), whereby four deaths were related to anastomotic leakage (1 and 3 patients with PE and without PE, respectively).Conclusion: PE is an interesting novel approach to improve gastric blood flow in order to minimize anastomotic leakage. Its application is safe and technically easy. Our preliminary experience revealed a decrease of the anastomotic leakage rate of almost 50%.

Inflammation d'une pinguécula ectopique [Inflammation of an ectopic pinguecula].

An 80-year-old male patient experienced recently diagnosed swelling of the limbal conjunctiva. In his clinical history were found cataract surgery on the right eye 3 months before, chronic open angle glaucoma effectively treated by local eye drops, treated systemic hypertension and hypercholesterolemia. On ophthalmic examination, a conjunctival mass was present in the inferior lateral conjunctival quadrant next to the limbus, with numerous vessels visible at its top. Treatment with topical corticosteroids failed to obtain regression, but decreased the local inflammatory signs. The persistence of the mass led to its surgical excision under local anesthesia. Histopathology found a subepithelial accumulation of modified collagen bundles typical of elastotic degeneration. Capillary vessels were seen in the superficial subepithelial area, attesting to the high degree of vascularization observed clinically. The final diagnosis was a pinguecula, which was not exactly located on the horizontal meridian area as it is usual.

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.

Holter implantable: reveal [The implantable loop recorder]

The implantable loop recorder developed by Medtronic (Reveal plus) is a small device inserted subcutaneously under local anesthesia in patients with syncope of unexplained origin. This device enables a single lead-ECG recording and has autonomy of two years. Memories are activated during episodes of bradycardia or tachycardia, either automatically or manually. Several studies have shown a high diagnostic rate reaching 50% and demonstrated its cost-effectiveness. There is also a significant reduction in syncopal episodes and a higher quality of life score in patients with syncope of unexplained origin.

Obstetric analgesia and anesthesia in Switzerland in 2007

Introduction: The last twenty years has witnessed important changes in the field of obstetric analgesia and anesthesia. In 2007, we conducted a survey to obtain information regarding the clinical practice of obstetric anesthesia in our country. The main objective was to ascertain whether recent developments in obstetric anesthesia had been adequately implemented into current clinical practice. Methodology: A confidential questionnaire was sent to 391 identified wiss obstetric anesthetists. The questionnaire included 58 questions on 5 main topics: activity and organization of the obstetric unit, practice of labor analgesia, practice of anesthesia for caesarean section, prevention of aspiration syndrome, and pain treatment after cesarean section. Results: The response rate was 80% (311/391). 66% of the surveyed anesthetists worked in intermediate size obstetric units (500-1500 deliveries per year). An anesthetist was on site 24/24 hours in only 53% of the obstetric units. Epidural labor analgesia with low dose local anesthetics combined with opioids was used by 87% but only 30% used patient controlled epidural analgesia (PCEA). Spinal anesthesia was the first choice for elective and urgent cesarean section for 95% of the responders. Adequate prevention of aspiration syndrome was prescribed by 78%. After cesarean section, a multimodal analgesic regimen was prescribed by 74%. Conclusion: When comparing these results with those of the two previous Swiss surveys [1, 2], it clearly appears that Swiss obstetric anesthetists have progressively adapted their practice to current clinical recommendations. But this survey also revealed some insufficiencies: 1. Of the public health system: a. Insufficient number of obstetric anesthetists on site 24 hours/24. b. Lack of budget in some hospitals to purchase PCEA pumps. 2. Of individual medical practice: a. Frequent excessive dosage of hyperbaric bupivacaine during spinal anesthesia for cesarean section. b. Frequent use of cristalloid preload before spinal anesthesia for cesarean section. c. Frequent systematic use of opioids when inducing general anesthesia for cesarean section. d. Fentanyl as the first choice opioid during induction of general anesthesia for severe preeclampsia. In the future, wider and more systematic information campaigns by the mean of the Swiss Association of Obstetric Anesthesia (SAOA) should be able to correct these points.
