Chirurgie de l'incontinence urinaire a l'effort féminine par voie transobturatrice: dehors-dedans ou dedans-dehors? Etude anatomique comparative

OBJECTIVE: Transobturator route is now largely used for the positioning of the supporting sub uretral tape in the surgical treatment of female urinary incontinence. This operation can be done using the original technique from the outside to the inside or by inside to outside. Our anatomic study evaluates the specific dangers of each MATERIAL AND METHODS: Our study is based on the dissection of seven fresh bodies, therefore 14 obturator regions. The dissections were done after the positioning of the tape from outside to inside on one side and inside to outside on the other side. We particularly studied the distances separating the tape from the inferior pudendal vascular bundle and the posterior branch of the obturator nerve. RESULTS: With the inside - outside technique there is a greater proximity between the path of the tape and the studied structures, therefore the risk of damage is greater. CONCLUSIONS: The two techniques are not equivalent. There are less vascular and neurological risk using the original outside to inside technique.

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.

Chirurgie de l'ongle incarné [Surgery for ingrowing toenails].

Ingrown toenail is a relatively frequent condition of the great toe affecting usually young adults. Surgery is most often required but the rate of recurrences is high with the risk of definitive functional and esthetical consequences. Among the numerous surgical procedures described, none is unanimously considered as the most effective. As for all dermatological surgery, the procedure must be not only curative but also esthetically acceptable. The surgeon's skills and experience are determining factors. A review of the most common procedures is presented.

Prise en charge de l'hémorragie du post-partum [Management of postpartum haemorrhage].

Today, postpartum hemorrhage remains a leading cause of maternal morbidity and mortality. Medical treatment, various surgical procedures and/or uterine artery embolisation have considerably reduced the risk of hysterectomy. It is important to identify the different risk factors of hemorrhage after delivery and to take the precautions to avoid it. A clear strategy defined by the obstetrical team is essential to decrease the delay in the management of this complication in order to increase the chances of a successful treatment.

Partial cricotracheal resection for pediatric subglottic stenosis: long-term outcome in 57 patients.

OBJECTIVE: We sought to assess the long-term outcome of 57 pediatric patients who underwent partial cricotracheal resection for subglottic stenosis. METHODS: Eighty-one pediatric partial cricotracheal resections were performed in our tertiary care institution between 1978 and 2004. Fifty-seven patients had a minimal follow-up time of 1 year and were included in this study. Evaluation was based on the last laryngotracheal endoscopy, the responses to a questionnaire, and a retrospective review of the patient's data. The following parameters were analyzed: decannulation rates, breathing, voice quality, and deglutition. RESULTS: A single-stage partial cricotracheal resection was performed in 38 patients, and a double-stage procedure was performed in 19 patients. Sixteen patients underwent an extended partial cricotracheal resection (ie, partial cricotracheal resection combined with another open procedure). At a median follow-up time of 5.1 years, the decannulation rates after a single- or double-stage procedure were 97.4% and 95%, respectively. Two patients remained tracheotomy dependent. One patient had moderate exertional dyspnea, and all other patients had no exertional dyspnea. Voice quality was found to improve after surgical intervention for 1 +/- 1.34 grade dysphonia (P < .0001) according to the adapted GRBAS grading system (Grade, Roughness, Breathiness, Asthenia, and Strain). CONCLUSIONS: Partial cricotracheal resection provides good results for grades III and IV subglottic stenosis as primary or salvage operations. The procedure has no deleterious effects on laryngeal growth and function. The quality of voice significantly improves after surgical intervention but largely depends on the preoperative condition.

Serum anticholinergic activity and postoperative cognitive dysfunction in elderly patients.

BACKGROUND: Cerebral cholinergic transmission plays a key role in cognitive function, and anticholinergic drugs administered during the perioperative phase are a hypothetical cause of postoperative cognitive dysfunction (POCD). We hypothesized that a perioperative increase in serum anticholinergic activity (SAA) is associated with POCD in elderly patients. METHODS: Seventy-nine patients aged >65 years undergoing elective major surgery under standardized general anesthesia (thiopental, sevoflurane, fentanyl, and atracurium) were investigated. Cognitive functions were assessed preoperatively and 7 days postoperatively using the extended version of the CERAD-Neuropsychological Assessment Battery. POCD was defined as a postoperative decline >1 z-score in at least 2 test variables. SAA was measured preoperatively and 7 days postoperatively at the time of cognitive testing. Hodges-Lehmann median differences and their 95% confidence intervals were calculated for between-group comparisons. RESULTS: Of the patients who completed the study, 46% developed POCD. Patients with POCD were slightly older and less educated than patients without POCD. There were no relevant differences between patients with and without POCD regarding gender, demographically corrected baseline cognitive functions, and duration of anesthesia. There were no large differences between patients with and without POCD regarding SAA preoperatively (pmol/mL, median [interquartile range]/median difference [95% CI], P; 1.14 [0.72, 2.37] vs 1.13 [0.68, 1.68]/0.12 [-0.31, 0.57], P = 0.56), SAA 7 days postoperatively (1.32 [0.68, 2.59] vs 0.97 [0.65, 1.83]/0.25 [-0.26, 0.81], P = 0.37), or changes in SAA (0.08 [-0.50, 0.70] vs -0.02 [-0.53, 0.41]/0.1 [-0.31, 0.52], P = 0.62). There was no significant relationship between changes in SAA and changes in cognitive function (Spearman rank correlation coefficient preoperatively of 0.03 [95% CI, -0.21, 0.26] and postoperatively of -0.002 [95% CI, -0.24, 0.23]). CONCLUSIONS: In this panel of patients with low baseline SAA and clinically insignificant perioperative anticholinergic burden, although a relationship cannot be excluded in some patients, our analysis suggests that POCD is probably not a substantial consequence of anticholinergic medications administered perioperatively but rather due to other mechanisms.

Postoperative cognitive dysfunction POCD, serum anticholinergic activity and intraoperative cerebral perfusion in geriatric patients

Background: Inadequate intraoperative cerebral perfusion and increased serum anticholinergic activity (SAA) have been suggested as possible causes of postoperative cognitive dysfunction (POCD). Methods: 53 patients aged >65 yrs undergoing elective major surgical procedures under standardized general anaesthesia. Cerebral perfusion was monitored with transcranial Doppler and near-infrared spectroscopy. Mx, an index of cerebral autoregulation was calculated based on the correlation of spontaneous changes inmean arterial blood pressure (MAP) and cerebral blood flow velocity. Cognitive function was measured preoperatively and 7 days postoperatively using the CERAD-Neuropsychological Battery. A postoperative decline >1 z-score in at least 2 cognitive variables was defined as POCD. SAA was measured preoperatively and 7 days postoperatively (data available for 38 patients). CRP was measured at the same time points and 2 days postoperatively. Results: Age was 75_7 yrs (mean_SD). 23 patients (43%) developed POCD. There were no statistical significant differences between patients with POCD and without POCD in age (77_7 vs 73_6 yrs), MAP (74_12 vs 78_11 mmHg), cerebral tissue oxygenation indices (67_6 vs 69_4 %) SAA preoperatively (1.74_1.52 vs 1.74_1.21) and 7 days postoperatively (1.90_1.63 vs 1.84_1.39) and CRP preoperatively (32_72 vs 7_9), 2 days postoperatively (176_129 vs 111_69) and 7days postoperatively (53_43 vs 48_25). Patients with POCD had less efficient autoregulation than patients without POCD (Mx 0.55_0.15 vs 0.45_0.20, p = 0.046). However, the percentage of patients with clearly impaired autoregulation (ie, Mx>0.5) was statistically not different between groups (with POCD: 65%; without POCD: 38%; p = 0.06) but there seems to be a trend. Conclusions: Our data on the association between cerebral perfusion and POCD in elderly patients are inconclusive and more patients need to be investigated. In this small group of patients SAA seems not to be associated with POCD.

Atrial fibrillation and minimally invasive coronary artery bypass grafting: risk factor analysis.

Atrial fibrillation (AF) is a frequent arrhythmia after conventional coronary artery bypass grafting. With the advent of minimally invasive technique for left internal mammary artery-left anterior descending coronary artery (LIMA-LAD) grafting, we analyzed the incidence and the risk factors of postoperative AF in this patient population. This prospective study involves all patients undergoing isolated LIMA-LAD grafting with minimally invasive technique between January 1994 and June 2000. Twenty-four possible risk factors for postoperative AF were entered into univariate and multivariate logistic regression analyses. Postoperative AF occurred in 21 of the 90 patients (23.3%) analyzed. Double- or triple-vessel disease was present in 12/90 patients (13.3%). On univariate analysis, right coronary artery disease (p <0.01), age (p = 0.01), and diabetes (p = 0.04) were found to be risk factors for AF. On multivariate analysis, right coronary artery disease was identified as the sole significant risk factor (p = 0.02). In this patient population, the incidence of AF after minimally invasive coronary artery bypass is in the range of that reported for conventional coronary artery bypass grafting. Right coronary artery disease was found to be an independent predictor, and this may be related to the fact that in this patient population the diseased right coronary artery was not revascularized at the time of the surgical procedure. For the same reason, this risk factor may find a broader application to noncardiac thoracic surgery.

Is the GraftConnector a valid alternative to running suture in end-to-side coronary arteries anastomoses?

BACKGROUND: An animal study was carried out to compare long-term patency rates of coronary anastomoses performed with the GraftConnector versus running suture technique. METHODS: 10 sheep, 45 to 55 kg, underwent off-pump coronary artery bypass grafting (right internal mammary artery to left anterior descending artery). In 5 animals, the anastomosis was performed with a GraftConnector and in 5 animals with 7-0 running suture. Intraoperative fluoroscopy and a fluoroscopic control at 6 months were performed. After 6 months, the animals were sacrificed and the anastomoses were examined histologically. RESULTS: All animals survived at 6 months with 100% anastomosis patency rates in both groups. In the GraftConnector group, the anastomosis diameter at 6 months fluoroscopy was 118% of native left anterior descending artery versus 97% of the control group. Luminal anastomotic width at histology was 1.7 +/- 0.2 mm in the device group versus 1.6 +/- 0.1 mm in the control group. Mean intimal hyperplasia thickness was 0.21 +/- 0.1 mm in the device group versus 0.01 mm in the control group. CONCLUSIONS: The GraftConnector provides a consistent and reproducible coronary artery anastomosis and reduces technical demand and manual dexterity in coronary operations. Long-term results demonstrate that off-pump coronary artery bypass grafting performed with the GraftConnector had the same patency rate and luminal width as those performed with running suture.
