Anterior Approach (anterior + approach)
Selected AbstractsPREPERITONEAL GROIN HERNIA REPAIR WITH KUGEL PATCH THROUGH AN ANTERIOR APPROACHANZ JOURNAL OF SURGERY, Issue 10 2008Junsheng Li Kugel hernia repair is classically carried out through the posterior approach; in this study we investigated the effectiveness and invasiveness of a Modified Kugel (Bard-Davol Inc., RI, USA) hernia repair procedure carried out through an anterior approach. A prospective series covering a 2-year period, including 122 patients (142 hernias) were carried out using the anterior approach. Patient comfort, complications and recurrence were evaluated. A total of 142 inguinal hernias were repaired, median age was 67 years, the mean operation time was 51 ± 23 min and the average incision was 4.5 cm. There was one case recurrence 5 months after repair. Other complications were few and not severe, only slight groin discomfort was observed in two patients during follow up. This Modified Kugel hernia through anterior approach is effective, mini-invasive and easy to learn with fewer complications.

Wiegel Background: Anterior sciatic nerve blocks can be complicated by several problems. Pain can be caused by bony contacts and, in obese patients, identification of the landmarks is frequently difficult. Methods: In a first step, 100 normal anterior-posterior pelvic X-rays were analyzed. The landmarks of the classical anterior approach were drawn on these X-rays and assessed for their sufficiency. Then, in a prospective case study, 200 consecutive patients undergoing total knee replacement were investigated. These patients received femoral and sciatic nerve catheters for postoperative pain management. Using modified anatomical landmarks, sciatic nerve catheters were inserted 5 cm distal from the insertion site of the femoral nerve block perpendicularly in the midline of the lower extremity. This midline connected the insertion site of the femoral nerve catheter to the midpoint between the medial and lateral epicondyle. Correct catheter positioning was verified by magnetic resonance imaging (MRI) in six patients. Results: Evaluation of pelvic X-rays showed that puncture following the classical landmarks pointed in 51% at the lesser trochanter, in 5% medial to the lesser trochanter and in 42% directly at the femur. In the latter patients, location of the sciatic nerve would have been difficult or even impossible. Using our modified anterior approach, the sciatic nerve could be blocked in 196 patients (98%). In nine patients (4.5%) blockade of the posterior femoral cutaneous nerve failed. Vascular puncture happened in 10 (5%) and bony contact in 35 patients (17.5%). Median puncturing depth was 9.5 (7.5,14) cm. Correct sciatic nerve catheter positioning was verified in all patients who underwent MRI. Conclusion: Our landmarks for locating the sciatic nerve help to avoid bony contacts and thereby reduce pain during puncture. Our method reliably enabled catheter placement. [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] Right hepatectomy by the anterior method with liver hanging versus conventional approach for large hepatocellular carcinomasBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 7 2010T.-J. Wu Background: The aim was to compare short-term results of right hepatectomy using the anterior approach (AA) and liver hanging manoeuvre with the conventional approach (CA) for large hepatocellular carcinoma (HCC). Methods: This was a retrospective review of 71 consecutive patients with HCC at least 5 cm in diameter who underwent curative right hepatectomy using either the AA with the liver hanging manoeuvre (33) or the CA (38) between January 2004 and December 2008. Clinical data, operative results and survival outcomes were analysed. Results: The groups had similar clinical, laboratory and pathological parameters. The AA group had larger tumours than the CA group (P = 0·039), but comparable grade and stage distribution. The operative results were similar except for an increased blood transfusion requirement with the conventional procedure (P = 0·001). The AA group had a lower recurrence rate (P = 0·003) and better disease-free survival (DFS) (P = 0·001) than the CA group, but overall survival rates were not significantly different (P = 0·091). Presence of tumour encapsulation, absence of tumour microvascular invasion and AA were predictive of DFS, whereas tumour stage was the only independent predictor of overall survival. Conclusion: The AA right hepatectomy with liver hanging manoeuvre for large HCC is associated with reduced blood transfusion requirement and lower recurrence rates in the short term.

[source] Prospective study of open preperitoneal mesh repair for recurrent inguinal hernia,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 1 2002M. Kurzer Background: Recurrent inguinal hernia presents a significant clinical problem with high re-recurrence and complication rates, particularly when an anterior approach is used. This study evaluated the open preperitoneal approach for repair of recurrent inguinal hernia. Methods: This was a prospective cohort study of 101 consecutive patients with 114 recurrent inguinal hernias. All were operated on using an open preperitoneal technique and prosthetic mesh by the method of Stoppa or Wantz. Follow-up was at 2,6 weeks, 15 and between 42 and 54 months. Results: There were no major complications. There was one infection and one case of retention of urine. There were no testicular complications. There were five recurrences, all within 6 months of operation, four of which were among the first 20 cases. Modifications to the original technique were made, and one recurrence occurred in the remaining 81 patients (1 per cent) or 106 hernias (1 per cent). Conclusion: Preperitoneal mesh repair gives results far superior to those of the commonly used anterior approach. It is safer and easier to learn than laparoscopic repair and is the procedure of choice for complex multirecurrent inguinal hernia. © 2002 British Journal of Surgery Society Ltd [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] 1353: Cryo-assisted anterior approach for surgery of retro-ocular orbital tumoursACTA OPHTHALMOLOGICA, Issue 2010N ROSEN Purpose The aim of this course is to share our experience with transconjunctival or transcutaneous anterior orbitotomy using surgical microscope and cryoextraction approach for surgery of retroocular orbital tumors. Methods Data regarding the used of this anterior surgical approach to retro-ocular orbital tumors was collected from our case series of 103 patients who, over 16 years, were operated on for retroocular orbital tumors and from a newer case series of 24 patients who, over the last 5 years were operated on for orbital cavernous hemangioma. Results A cryo-assisted, minimally invasive, anterior approach was employed in most patients. During more than 20 years lateral orbitotomy was needed only in 3 patients. The operations with anterior approach lasted 57.9 + 15.0 minutes. In none there was need for transformation into lateral orbitotomy and there were no intra-operative complications. No post operative deterioration of visual acuity was evident. Conclusion In contrast to other reports on treatment of orbital lesions, in our experience, surgery of most solid tumors and of many other cystic or infiltrative lesions can be achieved via an anterior, cryo-assisted approach, and thus with minimal trauma to the orbit. This approach warrants more favorable consideration as it can yield successful results even in cases with large or deeply located tumors. In most cases it obviates the need for extra-ocular muscle disinsersion and lateral or transcranial orbitotomies with bone flaps. [source] The applied anatomy of anterior approach for minimally invasive hip joint surgeryCLINICAL ANATOMY, Issue 2 2009Li Hua Chen Abstract The anterior approach for minimally invasive hip joint surgery is one of the common approaches utilized in hip joint surgery. Here, we report the results of dissections in 60 sides of human adult cadavers. We observed and measured the branches of the superficial circumflex iliac artery, the lateral femoral cutaneous nerves, the lateral circumflex femoral artery, and the superior gluteal nerves in the experiment via the anterior approach for minimally invasive hip joint surgery. The relationship between these structures and the anterior approach was studied. The present study provides important data demonstrating the location, path of dominant structures that might be encountered during the surgery and their relationships with the surgical incision. These data may allow surgeons performing the anterior approach for hip joint surgery to minimize the risk of neurovascular injury. Clin. Anat. 22:250,255, 2009. © 2008 Wiley-Liss, Inc. [source] Vocal Fold Paralysis After Anterior Cervical Spine Surgery: Incidence, Mechanism, and Prevention of Injury,THE LARYNGOSCOPE, Issue 9 2000Mark D. Kriskovich MD Abstract Objective Vocal fold paralysis is the most common otolaryngological complication after anterior cervical spine surgery (ACSS). However, the frequency and etiology of this injury are not clearly defined. This study was performed to establish the incidence and mechanism of vocal fold paralysis in ACSS and to determine whether controlling for endotracheal tube/laryngeal wall interactions induced by the cervical retraction system could decrease the rate of paralysis. Study Design Retrospective review and complementary cadaver dissection. Methods Data gathered on 900 consecutive patients undergoing ACSS were reviewed for complications and procedural risk factors. After the first 250 cases an intervention consisting of monitoring of endotracheal tube cuff pressure and release of pressure after retractor placement or repositioning was employed. This allowed the endotracheal tube to re-center within the larynx. In addition, anterior approaches to the cervical spine were performed on fresh, intubated cadavers and studied with videofluoroscopy following retractor placement. Results Thirty cases of vocal fold paralysis consistent with recurrent laryngeal nerve injury were identified with three patients having permanent paralysis. With this technique temporary paralysis rates decreased from 6.4% to 1.69% (P = .0002). The cadaver studies confirmed that the retractor displaced the larynx against the shaft of the endotracheal tube with impingement on the vulnerable intralaryngeal segment of the recurrent laryngeal nerve. Conclusion The study results suggest that the most common cause of vocal fold paralysis after anterior cervical spine surgery is compression of the recurrent laryngeal nerve within the endolarynx. Endotracheal tube cuff pressure monitoring and release after retractor placement may prevent injury to the recurrent laryngeal nerve during anterior cervical spine surgery. [source] | ||||||||||
