Selected AbstractsCurettage prior to Mohs' Micrographic Surgery for Previously Biopsied Nonmelanoma Skin Cancers: What Are We Curetting?DERMATOLOGIC SURGERY, Issue 1 2005Comparative Study, Prospective, Retrospective Background Curettage prior to excision and Mohs' micrographic surgery for nonmelanoma skin cancer is performed based on the assumption that the curette will remove softer, more friable tumor-infiltrated dermis and leave structurally intact normal skin. This assumption, however, has not been objectively examined in the dermatologic surgery literature. Objective We performed a study to examine the ability of curettage to selectively remove and delineate nonmelanoma skin cancer prior to Mohs' micrographic surgery. Methods The study included 150 previously biopsied basal cell and squamous cell carcinomas less than 1.5 cm in size. We conducted (1) a retrospective study of 50 tumors curetted prior to Mohs' surgery by a surgeon who routinely curettes preoperatively; (2) a prospective study in which a surgeon who routinely does not curette preoperatively curetted 50 tumors prior to Mohs' surgery; and (3) a comparative historical group of 50 noncuretted tumors treated with Mohs' surgery by the latter surgeon. All curetted tissue was evaluated histologically. Results Only 50% of the curetted tissue demonstrated the presence of tumor in the curettings, but in 76% of these, the curette left residual tumor at the surgical margins. Of the other 50% in which the curette removed only non,cancer-containing skin, 34% had tumor present at the surgical margin. Overall, the curette removed tumor, leaving no residual tumor at the surgical margins in only 12% of lesions. Comparison with historical noncuretted tumors operated on by the same surgeon showed that curettage did not affect the mean number of stages or the proportion of tumors requiring more than one stage for histologic clearance. Conclusion Although curettage may be helpful in debulking friable skin prior to Mohs' micrographic surgery, it does not reliably delineate the extent of a tumor. MING H. JIH, MD, PHD, PAUL M.

[source] Myopexy (Faden) results in more postoperative vomiting after strabismus surgery in childrenACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2001M. Saiah Background: Strabismus correction in children is associated with a high incidence of postoperative nausea and vomiting. The purpose of this prospective, double-blind study was to examine the influence of the surgical method for correction of squint on the incidence of postoperative vomiting. Methods: One hundred and twenty consecutive children aged 2,12 years, scheduled for elective strabismus surgery, were enrolled in this prospective, double-blind study. A standardised total intravenous anaesthesia was given to all children. The development of perioperative oculocardiac reflex was noted and the number of episodes of vomiting during the first 48 h postoperatively was recorded. At the completion of the study, the children who were operated with myopexy according to Faden, were allocated to a Faden group, those without a myopexy to the non-Faden group. All the patients included in this study were operated on by the same surgeon with standardised techniques. Results: The Faden group was younger, lighter and the operation time was longer (P<0.05). The incidence of vomiting was greater in the Faden group; 53% versus 12% (P<0.05). The incidence of oculocardiac reflex was similar in both groups; 40% in the Faden versus 28% in the non-Faden group, respectively. The total dose of propofol and alfentanil was similar between the groups. Requirement of analgesics for postoperative pain was similar in both groups. The only independent risk factor for postoperative vomiting was the Faden operation. Conclusion: The surgical method used for strabismus correction in children has a great influence on the incidence of postoperative vomiting. The Faden operation is associated with a very high incidence of postoperative vomiting; this particular group of patients has to be considered as a high risk group for postoperative vomiting and deserves an antiemetic prophylaxis. [source] The Surgical Learning Curve in Aural Atresia SurgeryTHE LARYNGOSCOPE, Issue 1 2007FRACS, Nirmal Patel MBBS (Hons) Abstract Objective: The objective of this retrospective case review is to examine the effect of surgical learning on hearing outcomes and complications in congenital aural atresia surgery. Patients: Sixty-four consecutive ears (in 60 patients) operated on during the period of 1994 to 2004 at a tertiary referral center were studied. Intervention)s): Intervention consisted of aural atresiaplasty through an anterior approach by the same surgeon (C.S.). Main Outcome Measure)s): Hearing outcomes and complication rates were compared between four temporally sequential groups of 16 ears. Acceptable hearing and complication rate outcomes were defined as results comparable to larger series in the literature. Results: Hearing results, in the short term, comparable to larger series were achieved during the first group of ears (nos. 1,16). A plateau in the learning curve for short-term hearing outcomes was achieved after the first two groups, that is, after 32 ears. Hearing outcomes, in the long term (>1 year) comparable to larger series, were achieved in the second group of ears (nos. 16,32). The learning curve for long-term hearing demonstrated a significant improvement in outcomes in the final group of 16 ears compared with the first 48 ears. Long-term hearing results for the final group show closure of the postoperative air-bone gap to less than 30 dB in 94% of cases. Postoperative complication rates were equivalent to larger series in the first group of 16 ears and showed no statistically significant difference between the four groups. There was one patient with sensorineural hearing loss after surgery; there were no anacoustic ears and no facial palsies in the study group. Conclusions: A learning curve of at least 32 ears was required to achieve stable short-term hearing results. To achieve stable long-term hearing results required a learning curve of at least 48 patients in our series. Complication rates remained stable throughout the study period. [source] Anal stenosis: use of an algorithm to provide a tension-free anoplastyANZ JOURNAL OF SURGERY, Issue 5 2010Zeev Duieb Abstract Background:, Anal stenosis is a debilitating condition that often is iatrogenic in cause. Various surgical procedures to manage this problem have been described. The present study evaluates the use of different anoplasty techniques in a series of 11 patients with anal stenosis. To the best of the authors' knowledge, this is the first study to provide a stepwise algorithm for the anoplasty techniques used. Methods:, A series of 11 patients were evaluated for presenting symptoms, cause of anal stenosis, type of anoplasty used, complications and post-operative success in relieving symptoms. All operations were performed by one surgeon in three hospitals, and were followed up by the same surgeon and by a surgical registrar. Results:, The most common presenting symptoms were constipation and decreasing calibre of stool. The main causes of anal stenosis were previous surgery, neoplasia and fissure. Transverse closure, Y-V and diamond advancement flaps were used in an escalating manner to deal with increasing severity of stenosis. All 11 patients had some level of improvement in symptoms post-operatively. There were no long-term complications. Conclusion:, Anoplasty is a safe and successful option in the treatment of anal stenosis, and this stepwise algorithm takes the guesswork out of choosing the most appropriate procedure for each patient. [source] Cryo-assisted anterior approach for surgery of retroocular orbital tumours avoids the need for lateral or transcranial orbitotomy in most casesACTA OPHTHALMOLOGICA, Issue 6 2010Nachum Rosen Acta Ophthalmol. 2010: 88: 675,680 Abstract. Purpose:, To describe and evaluate a cryo-assisted, minimally invasive, anterior approach for orbital tumour surgery. Methods:, Retrospective, non-comparative, consecutive, interventional case series of 103 patients who were operated on by the same surgeon for retroocular orbital tumours over the last 16 years. Results:, A cryo-assisted, minimally invasive, anterior approach was employed in 63 out of the 103 patients (61.2%). In 37 patients (35.9%), anterior orbitotomy without the use of cryoprobe was employed for biopsy or excision of small, anteriorly located lesions. Lateral orbitotomy was used in three patients (2.9%). In a subgroup of 61 patients with circumscribed lesions (mainly cavernous haemangiomas and schwannomas), cryoextraction was used in 51 (83.6%). None of the procedures required conversion to lateral orbitotomy and there were no intraoperative complications. Conclusion:, In contrast to other reports on the treatment of orbital lesions, in the current case series surgery of most solid tumours and many other cystic or infiltrative lesions was achieved here via an anterior, cryo-assisted approach, and thus with minimal trauma to the orbit. This approach warrants more favourable consideration because the combination of the anterior approach with the use of cryoprobe and surgical microscope can yield successful results, even in patients with large or deeply located tumours , obviating in most of them the need for lateral or transcranial orbitotomies with bone flaps. [source] 23G versus 20G for macular hole surgery.ACTA OPHTHALMOLOGICA, Issue 2009Efficacy, patient satisfaction, safety Purpose To compare the 20gauge and 23gauge vitreoretinal surgical system and equipment in macular hole surgery. Methods We randomly assigned 38 patients in two different groups. Group 1. Used 20g surgical equipment and instrumentation. Group 2. Used 23g surgical equipment and instrumentation. All cases were operated by the same surgeon. The efficacy, the safety and the patient comfort were evaluated. Results No statistically significant difference found between the two groups regarding efficacy and complications. Group 2 was superior to group 1 regarding patient satisfaction (p<0.005). Conclusion 23g surgical equipment offers similar efficacy to the established 20g equipment for macular hole surgery. Though reduces the intraoperative time and patient overall satisfaction is greater. [source] Micro Incisional Vitrectomy (MIVS): a new device for trocar insertionACTA OPHTHALMOLOGICA, Issue 2008S RIZZO Purpose Despite its clinical advantages, MIVS poses significant challenges in performing airtight incisions especially dealing with 23-gauge system. Aim of this paper was to assess the feasibility of performing 23-g MIVS using an injector system for trocar insertion. Methods 60 consecutive eyes of 56 patients underwent 23-g pp vitrectomy and gas endotamponade for the treatment of Regmatogenous Retinal detachment and Diabetic Prolipherative Retinopathy by the same surgeon (SD). 30 eyes were operated on with standard one-step 23-g and 30 using a prototype of injector holding the same 23-g trocar cannula system. The trocar squeezed into the plunger of the injector. The device had a metallic terminal oriented with a fix angle, allowing the insertion in the settled direction, able to fix the globe and displace the conjunctiva at the same time.Main outcome measure were sclerotomies airtightness, surgical time and complications. Results In the 30 eyes operated with the 23-g ones step system 9 sclerotomies were sutured, in 5 refilling was required. Mean surgical time were 54 minutes. In the 30 eyes operated with the new device, the inserter was easy to apply in all cases and was useful especially in the nasal quadrant. Also dealing with sunken eyes the inclination of the system 5-10° tangential to the sclera was easily achieved. No suture was placed, refilling was needed in 3 cases. Mean surgical time was 45 minutes. No complications due to these device were highlighted. Conclusion The new injector was safe and effective. The device facilitates the insertion manoeuvre allowing easier and quicker trocar positioning helping the airtight wound construction. MIVS success lie in the surgeon's skill but also in the development of the technology and instrumentations. [source] | ||||||||||
