Laparoendoscopic single site (LESS) has recently gained momentum as feasible techniques for minimal access surgery. Our aim is to describe the current status of laparoendoscopic single site (LESS) in pelvic surgery. A comprehensive revision of the literature in LESS pelvic surgery was performed. References for this manuscript were obtained by performing a review of the available literature in PubMed from 01-01-01 to 30-11-11. References outside the search period were obtained selected manuscripts bibliography. Search terms included: pelvic anatomy, less in gynecology, single port colectomy, urological less, single port, single site, NOTES, LESS and single incision. 314 manuscripts were initially identified. Out of these, 46 manuscripts were selected based in their pelvic anatomy or surgical content; including experimental experience, clinical series and literature reviews. LESS drastically limit the surgeon's ability to perform in the operative field and the latter becomes hardened by the lack of space in anatomical location like the pelvis. Potential advantages of LESS are gained with the understanding that the surgical procedure is more technically challenging. Pelvic surgical procedures related to colorectal surgery, gynecology and urology have been performed with LESS technique and information available is mostly represented by case reports and short case series. Comparative series remain few. LESS pelvic surgery remain in its very beginning and due to the very specific anatomical conditions further development of LESS surgery in the mentioned area can be clearly be facilitated by using robotic technology. Standardization ad reproducibility of techniques are mandatory to further develop LESS in the surgical arena.

To evaluate the clinical presentation, treatment outcome and follow-up of all patients managed with sinonasal papillomas (SP), at a tertiary private otorhinolaryngology centre in Caracas (Venezuela).We reviewed 94 patients with SP that were treated at our otolaryngology center, from July 1st 1993 to June 31st 2015. The demographic data, clinical features, radiological findings, anatomical origin, disease extension into the adjacent structures, surgical approaches performed, histopathology outcomes, recurrent risk, malignant transformation rate and coadjuvant therapies were assessed.Sixty-five patients (69.1%) were male and 29 (30.9%) female with an average age of 44.5 years (range 9-80 years). All patients underwent endoscopic sinus surgery. The most commont histologic subtypes of SP were inverted papilloma (58 patients; 61.7%), fungiform papilloma (35 patients; 37.2%) and oncocytic papilloma (one patient; 1.1%). SP was associated in 2 patients with undifferentiated squamous cell carcinoma. Twelve patients (12.8%) had disease with extension beyond the sinus without associated malignancy. All these patients received adjuvant treatment with advanced techniques of radiotherapy. The mean duration of the follow-up period was 9 years and 2 months. Eighteen patients (19.1%) had recurrent disease during the entire course of follow-up.Complete endoscopic surgical removal of SP is the treatment of choice. In less endoscopically accessible tumours, with peripheral extension or incompletely resected, Intensity Modulated Radiotherapy and Volumetric Modulated Arc Therapy may be indicated. Timely post-operative endoscopic follow-up with biopsy of suspected lesions is important for early detection of recurrences and associated malignancy.

Background: Natural orifice translumenal endoscopic surgery (NOTES) has been used to perform nephrectomy in the laboratory; however, clinical reports to date have used multiple abdominal trocars to assist the transvaginal procedure. Objective: To present our stepwise technique development and the first successful clinical case of NOTES transvaginal radical nephrectomy for tumor with umbilical assistance without extraumbilical skin incisions. Design, setting, and participants: The four transvaginal NOTES procedures were performed at two institutions after obtaining institutional review board approval. Various operative steps were developed experimentally in three clinical cases, and on March 7, 2009, we performed the first successful case of NOTES hybrid transvaginal radical nephrectomy without any extraumbilical skin incisions. Using one multichannel access port in the vagina and one in the umbilicus, laparoscopic visualization, intraoperative tissue dissection, and hilar control were performed transvaginally and transumbilically. The intact specimen was extracted transvaginally. Measurements: All perioperative data were accrued prospectively. A stepwise progression to the successful completion of the fourth case is systematically presented. Results and limitations: Intraoperatively, at incrementally more advanced stages of the procedure, the first three NOTES clinical cases were electively converted to standard laparoscopy because of rectal injury during vaginal entry, of failure to progress, and of gradual bleeding during upper-pole dissection after transvaginal hilar control, respectively. The fourth case was successfully completed via transvaginal and umbilical access without conversion to standard laparoscopy. Operative time was 3.7 h, estimated blood loss was 150 cm3, and hospital stay was 1 d. Final pathology confirmed a 220-g, pT1b, 7-cm, grade 2, clear-cell renal cell carcinoma with negative margins. The patient was readmitted for an intraabdominal collection that responded to drainage and antibiotics. Conclusions: We report our stepwise progression and the initial successful clinical case of NOTES hybrid transvaginal radical nephrectomy for tumor, assisted with only one umbilical trocar. Although transvaginal nephrectomy is feasible in the highly selected patient with favorable intraoperative circumstances, considerable refinements in technique and technology are necessary if this approach is to advance beyond mere anecdote. © 2009.

Urological fistulas are an underestimated problem worldwide and have devastating consequences for patients. Many urological fistulas result from surgical complications and/or inadequate perinatal obstetric healthcare. Surgical correction is the standard treatment. This article reviews minimally invasive surgical approaches to manage urological fistulas with a particular emphasis on the robotic techniques of fistula correction. RECENT FINDINGS: In recent years, many surgeons have explored a minimally invasive approach for the management of urological fistulas. Several studies have demonstrated the feasibility of laparoscopic surgeryand the reproducibility of reconstructive surgery techniques. Introduction of the robotic platform has provided significant advantages given the improved dexterity and exceptional vision that it confers. SUMMARY: Fistulas are a concern worldwide. Laparoscopic surgery correction has been developed through the efforts of several authors, and difficulties such as the increased learning curve have been overcome with innovations, including the robotic platform. Although minimally invasive surgery offers numerous advantages, the most successful approach remains the one with the surgeon is most familiar. © 2015 Wolters Kluwer Health, Inc.

The aim of this study is to analyze the current literature on single port radical prostatectomy (LESS-RP). Single port radical prostatectomy laparoendoscopic (LESS-RP) has established itself as a challenge for urological community, starting with the proposal of different approaches: extraperitoneal, transperitoneal and transvesical, initially described for laparoscopy and then laparoscopy robot-assisted. In order to improve the LESS-RP, new instruments, optical devices, trocars and retraction mechanisms have been developed. Advantages and disadvantages of LESS-RP are controversial, while some claim that it is a non-trustable approach, regarding the low cases number and technical difficulties, others acclaim that despite this facts some advantages have been shown and that previous described difficulties are being overcome, proving this is novel proposal of robotics platform, the Da Vinci SP, integrating the system into Y. The LESS-RP approach gives us a new horizon and opens the door for rapid standardization of this technique. The few studies and short series available can be result of a low interest in the application of LESS-RP in prostate, probably because of the technical complexity that it requires. The new robotic platform, the da Vinci SP, shows that it is clear that the long awaited evolution of robotic technologies for laparoscopy has begun, and we must not lose this momentum.

Objective: We describe the clinical features of a 17-year-old girl with severe asthma exacerbations. On admission to the intensive care unit, she manifested expiratory dyspnea, cyanosis, and an unproductive cough. Her chest x-rays showed extensive pneumomediastinum (PM), mild subcutaneous emphysema at the right anterior triangle of the neck, and right upper-lobe atelectasis. Her PM resulted from the "Macklin effect," which involves a three-step process: overly distended alveolar rupture, air dissection along the bronchovascular sheaths, and air spreading into the mediastinum. Methods: Treatment consisted of oxygen therapy, parenteral corticosteroids, and nebulized bronchodilators. Results: She made a good recovery, and was discharged from the intensive care unit after 2 days. Conclusion: This case illustrates that conservative management strategies in this severe and unusual complication of asthma exacerbation can result in rapid and complete recovery. Nonetheless, every asthma exacerbation should be considered potentially life-threatening, and must be treated promptly and adequately. © 2010 Elsevier Inc.

Purpose: We describe our initial experience with intrafascial robot-assisted simple prostatectomy (IF-RSP). Potential advantages include reduced blood loss, elimination of the need for postoperative bladder irrigation, and elimination of the risk of residual or future prostate cancer, without interrupting potency or continence. Patients and Methods: From June 2011 to March 2012, 10 patients with symptomatic prostatomegaly on transrectal ultrasonography (TRUS) (mean 81 g) underwent IF-RSP. Three patients had acute urinary retention. Demographic perioperative and outcome data were recorded up to 1 month follow-up. Results: Average age was 71.7 years (range 60-79 years), estimated blood loss was 375 mL (range 150-900 mL), operative time was 106 minutes (range 60-180 min), hospital stay was 1 day (range 0-3 days), and Foley catheter duration was 8.9 days (range 6-14 days). The drain was removed at a mean 2.8 days (range 0-8 days). Mean prostate volume on preoperative TRUS was 81 cc (range 47-153 cc). Mean specimen weight was 81 g (range 50-150 g). Improvement was noted in the International Prostate Symptom Score (preoperative vs postoperative 18.8 vs 1.7) and peak flow rate (12.4 vs 33.49 mL/min). Sexual Health Inventory for Men score ranged from 12 to 24. All patients were completely continent within 1 month postoperatively, and sexual function was preserved. One patient had urinary tract infection and one patient needed blood transfusion postoperatively. Conclusions: IF-RSP appears to be a feasible procedure in large-volume prostatomegaly. The entire prostate tissue is removed without compromising continence and potency. Larger series and longer-term follow-up are needed to evaluate the proper place of this approach. © Copyright 2013, Mary Ann Liebert, Inc. 2013.

OBJECTIVE: To analyze results of combined treatment of cervical cancer. METHODS: In 236 medical records were reviewed between the years 2000-2010 at GURVE, Oncological Radiotherapy Unit. The patients received a treatment of external radiotherapy that consisted in 4 500 cGy to pelvis plus 1 000 cGy to parametrium, concurrent with weekly chemotherapy using cisplatin (40 mg/m2), followed by high rate of brachytherapy. RESULTS: The age range was between 26 and 86 years old, with an average of 52.3 and a median of 51 years. The largest group age was between 41 and 60 years old. The most common histological variety was the epidermoid (75.7 %). The 81.7 % of the patients received radiotherapy concurrent with chemotherapy, followed or interspersed with the brachytherapy. It was observed that the 50.6 % of the patients reached the complete treatment time in less than 8 weeks. 110 patients achieved it over the 8 weeks. 223 patients received brachytherapy. At present time, 163 (69.3 %) are alive free of disease, 24 of them continued with disease (10.21 %); 8 patients died for different causes (3.40 %) and 40 patients died with the disease, (17.02 %). The average time of follow-up was of 46.5 months (April 2012). The overall survival was 77.8 % at 5 years. CONCLUSIONS: Our results are similar with international publications. To add cisplatin as standard therapy reduce recurrence and death related disease for all the stages. Treatments appropriate time periods ensure better survival.

The patients with advanced disease and terminal state may have refractory symptoms, producing a great suffering for it palliative sedation therapy is used. But their use is controversial; this is a review attempts to clarify the ethical concepts, the decision making for it use, and so clarify the moral legitimacy.

Introduction: Duplication of the ureter and renal pelvis is the most common anomaly of the upper urinary tract. Upper pole heminephrectomy is a treatment option when duplication anomalies are associated with ureteral ectopia or ureterocele with an associated nonfunctioning or infected upper pole moiety. Material and method: We describe a NOTES hybrid transvaginal upper pole heminephrectomy in a 24 year old with recurrent infections in a poorly functioning right upper pole moiety. The procedure was performed with a bariatric trocar in the vagina, and a multichannel single-port device (Triport, Olympus Surgical) in the umbilicus. An ultrasonic scalpel was used for the heminephrectomy. The specimen was retrieved through the vagina. Results: Operative time was 150 minutes and blood loss 50 cc. One week later the patient developed urinoma at the surgical site and was re-explored laparoscopically. The cut edge of the heminephrectomy defect was fulgurated and a drain placed. The patient recovered uneventfully following re-exploration. Conclusions: We describe the technique for transvaginal Hybrid-NOTES heminephrectomy. This approach requires further development with respect to instrumentation, and surgical expertise. The combined umbilical and vaginal approached restored triangulation and facilitates dissection, but more experience is required to determine safety, efficacy and reproducibility. © 2010 AEU.
