Versatility of nasolabial flaps in oral cavity reconstructions
2014
Objectives: Describe the techniques involved and the results obtained witn nasolabial flaps in small and medium- sized defects of the oral cavity. The procedure is an easy resconstructive option with a high success rate and with very good aesthetic and functional outcomes. Study Design: A retrospective analysis of 16 nasolabial flap reconstructions in 15 oncological patients with oral cavity defects undergoing single-stage surgical interventions. We evaluate the tumor type, its location, size, the resective and reconstructive techniques involved, as well as any complications. Results: Out of 15 patients, 9 were male and 6 female, with ages ranging from 60-85 years. The primary tumor was loc…
The changes in resting anal pressure after performing full-thickness rectal advancement flaps.
2017
Background: Advancement flap is an accepted approach for treating complex fistula-in-ano. The purpose was to evaluate the changes in resting pressure along the anal canal after performing a full-thickness flap. Methods: Manometric review of patients who have undergone a full-thickness rectal advancement flap procedure for complex anal fistulas of cryptoglandular origin. Recurrence and continence were evaluated. Resting Anal Pressure was assessed along the anal canal by two measures: maximum resting pressure(MRP) and inferior resting pressure(IRP) at 0.5 cm from the anal verge. Results: 119 patients were evaluated. Overall recurrence rate was5.9%. Anal continence was maintained intact in 76.…
Further application of the bilobed flap: the split bilobed flap for reconstruction of composite posterior auricular and mastoid defects
2006
In this article a modified bilobed flap from mastoid and lateral neck skin for reconstruction of complex defects of the posteromedial surface of the auricle and mastoid skin, with the preservation of the retroauricular sulcus, is described. Reconstruction of the postero-medial auricular surface has almost never been a concern for reconstructive surgeons. It is in fact a shaded area with little aesthetic relevance and direct closure, skin grafting and even secondary healing are used for skin cancer defects repair. Also mastoid skin defects can be repaired with simple techniques such as skin grafts or transposition flaps from the remaining mastoid skin or from the neck. On the other hand, can…
Long-Term Followup of Children with Colon Conduit Urinary Diversion and Ureterosigmoidostomy
1977
Sixty-four children underwent colon conduit urinary diversion because of a neurogenic bladder owing to myelomeningocele and 39 children required a ureterosigmoidostomy because of bladder exstrophy. The average length of followup was 4.6 years after colon conduit and 5.6 years after ureterosigmoidostomy. Colon conduit diversion was secondary in 3 children and ureterosigmoidostomy was secondary in 5. Of the children with a colon conduit 9.4% and of those with ureterosigmoidostomy 12.8% had postoperative surgical complications. Late surgical complications were encountered after colon conduit in 14.5% and after ureterosigmoidostomy in 20%. Of the children with normal renal function preoperative…
Preemptive hydrocelectomy in subinguinal varicocelectomy
2008
<i>Background/Aims:</i> The hydrocele rate is very low after microsurgical subinguinal varicocelectomy, but microsurgical expertise is not always available in pediatric centers. We describe a modified technique to reduce the hydrocele rate after subinguinal varicocelectomy performed without an operating microscope. <i>Methods:</i> A retrospective review was performed of 142 non-microsurgical subinguinal varicocelectomies performed at a single pediatric center. In 96 patients, varicocelectomy was combined with the excision and eversion of the tunica vaginalis (‘pre-emptive hydrocelectomy’) while in the remaining 46 cases the vaginalis was left untouched. <i>Resu…
Towards a glioma model for surgical technique evaluation in the rat.
2013
Evaluation of new surgical techniques in animal models is frequently challenging. This article describes the pitfalls, peculiarities and the final best applicable model for evaluating surgical techniques for glioma resection.The C6 glioma cell line and the Sprague-Dawley rat strain were selected. Fifty-thousand glioma cells were stereotactically transplanted in the left hemisphere of 137 male adult rats. Evaluation of solid tumour formation, tumour growth and scheduling of surgical resection was performed by MR scanning at 1, 2, and 4 weeks after transplantation and 3 and 6 months after tumour resection. Microsurgical tumour resection was performed with conventional techniques or with the w…
Safety of Reconstructive Microsurgery in the Elderly Population: a Multicentric Prospective Study
2021
Background: Safety of reconstructive microsurgery in elderly patients is still a topic of debate, because no conclusive evidence exists that provides indications and risk evaluation in elderly patients. The purpose of this study, which the Italian Society for Plastic, Reconstructive, and Aesthetic Surgery (SICPRE) has promoted, is to evaluate the safety and the complication risk of elective reconstructive microsurgery in elderly patients as well as to identify patient- or procedure-related risk factors. The secondary aim is to evaluate the predictive role for complications of the Geriatric 8 score (G8). Methods: A total of 194 consecutive patients from 18 centers, aged 65 or older, who rece…
Acute Kidney Injury After Percutaneous Edge-to-Edge Mitral Repair.
2020
BACKGROUND In catheter-based procedures, acute kidney injury (AKI) is a frequent, serious complication ranging from 10% to 30%. In MitraClip (Abbott Vascular, Santa Clara, California), a usually contrast-free procedure, there is scarce data about its real incidence and impact. OBJECTIVES This study aimed to evaluate incidence, predictive factors, and midterm outcomes of AKI in patients with significant mitral regurgitation (MR) undergoing transcatheter valve repair with MitraClip. METHODS A total of 721 patients undergoing MitraClip were included. AKI was defined as an absolute or a relative increase in serum creatinine of >0.3 mg/dl or >= 50%, respectively, or the need for hemodialysis dur…
Impact of perceptual ability and mental imagery training on simulated laparoscopic knot-tying in surgical novices using a Nissen fundoplication model.
2011
Background: Performing minimally invasive surgery requires training and visual-spatial intelligence. The aim of our study was to examine the impact of visual-spatial perception and additional mental training on the simulated laparoscopic knot-tying task performed by surgical novices. Methods: A total of 40 medical students randomly assigned to two groups underwent two sessions of laparoscopic basic training on a VR simulator (SimSurgery®, Oslo, Norway). The variables time and tip trajectory (total path length of the instrument tip trajectory) were used to assess the performance of the intracorporeal knot-tying task using a laparoscopic Nissen fundoplication model. The experimental group com…
Mycotic Aneurysm of Both Internal Iliac Arteries due to Candida albicans.
2013
International audience; : We report the case of a 21-year-old man, with a Candida-related endocarditis causing multiple emboli and bilateral false aneurysms of the internal iliac arteries. As the distal runoff vasculatures of both internal iliac arteries were occluded, these arteries required ligation. Although there were few consequences with the procedure, multiple emboli and recurrence of endocarditis after cardiac surgery led to the patient's death.
