Project description:BackgroundAs laparoscopy becomes a standard approach in many urological procedures, researchers strive to make minimally invasive surgery less invasive. Our objective was to apply recent innovations in equipment and surgical approaches to develop the technique and perform laparo-endoscopic single site radical prostatectomy (LESS-RP).MethodsThe technique for LESS-RP was derived by combining existing techniques of standard laparoscopic RP and developing techniques of urological LESS. This incorporated newly available low-profile trocars, flexible instruments and a flexible-tip laparoscope. The procedure was performed through a single 3-cm transverse infra-umbilical incision. LESS-RP was completed successfully via a single operative site without auxiliary needles or trocars. Perioperative variables and postoperative outcomes were recorded and measured.ResultsThe operative time was 424 min and the hospital stay was 10 days because of a vesicourethral leak and ileus. The anastomotic leak resolved and the urethral catheter was removed at 4 weeks after surgery. The final pathology showed negative margins and Gleason 3 + 4 pT2c prostatic adenocarcinoma.ConclusionsLESS-RP is feasible by replicating laparoscopic RP techniques and incorporating the LESS technique with the advent of flexible-tip laparoscopes and flexible instruments. After a learning curve has been overcome, this should be further tested prospectively to compare oncological and functional outcomes with laparoscopic and robotic-assisted RP.

Project description:ObjectiveThe purpose of this review is to assess the efficacy and safety of laparo-endoscopic local resections for colorectal lesions not suitable for endoscopic resection.Summary background dataThe combined laparo-endoscopic approach has been proposed for large colorectal lesions unsuitable for endoscopic resection, in order to reduce morbidity of common laparoscopic resection. However, data on the efficacy and safety of laparo-endoscopic local resections are still controversial.MethodsAn Embase search of papers published during the period 1985-2014 was performed. Published studies that evaluated laparo-endoscopic resections for colorectal lesions were assessed using PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) recommendations by two authors. Forest plots on primary (per-lesion rate of further surgery, including surgery for complications and surgery for oncologic radical treatment) and secondary outcomes were produced based on fixed and random effects models. Heterogeneity was assessed using the I (2) statistic. Risk for within-study bias was ascertained with QUADAS (Quality Assessment of Diagnostic Accuracy Studies) system.ResultsA total of 11 studies provided data on 707 lesions treated with a combined laparo-endoscopic approach. A variety of techniques were reported. The overall per-lesion rate of further surgery was 9.5%, while per-lesion rate of further surgery for oncologic treatment was 7.9%, per-lesion rate of further surgery for complications treatment was 3.5%, incidence of adenocarcinoma was 10.5%, incidence of overall complications was 7.9%, incidence of conversion to open surgery 4.3% and incidence of recurrence was 5.4%.ConclusionsDespite laparo-endoscopic approach ensures limited invasiveness, it is affected by a consistent rate of complications and oncologic inadequacy that often requires further surgical treatment.

Project description:In the current study, we reported our initial experience of gasless transoral endoscopic thyroidectomy vestibular approach (TOETVA) by novel trocars and a suspension system. Between February 2019 to September 2020, thyroid cancer patients with indicated central lymph node metastasis by imaging examination who had received gasless TOETVA by our designed trocars and suspension system in The First Affiliated Hospital of University of Science and Technology of China were reviewed. A total of 95 thyroid cancer patients that received gasless TOETVA were included in this analysis. Of note, 73 cases underwent one-sided lobectomy and the remaining 22 cases underwent total thyroidectomy. All thyroid cancer patients underwent central lymph node dissection (CND). The average total examined lymph nodes number was 8.55 ± 5.67 per individual. No serious complications occurred during or after the operation besides one patient who had a short-term recurrent laryngeal nerve (RLN) deficit and one patient who had delayed postoperative bleeding. In conclusion, the use of novel trocars and a suspension system can effectively improve the safety and efficacy of TOETVA.

Project description:Currently, over 80% of radical prostatectomies have been performed with the da Vinci Surgical System. In order to improve the aesthetic outlook and decrease the morbidity of the operation, the new da Vinci Single Port (SP) system was developed in 2018. However, one major problem is the SP system is still not available in most countries. We aim to present our initial experience and show the safety and feasibility of the single-site robotic-assisted radical prostatectomy (LESS-RP) using the da Vinci Single-Site platform. From June 2017 to January 2020, 120 patients with localized prostate cancer (stage T1-T3b) at Kaohsiung Medical University Hospital were included in this study. We describe our technique and report our initial results of LESS-RP using the da Vinci Si robotic system. Preoperative, intraoperative and postoperative patient variables were recorded. Prostate-specific antigen (PSA)-free survival was also analyzed. A total of 120 patients were enrolled in the study. The median age of patients was 68 years (IQR 63-71), with a median body mass index of 25 kg/m2 (IQR 23-27). The median PSA value before operation was 10.7 ng/mL (IQR 7.9-21.1). The median setup time for creat-ing the extraperitoneal space and ports document was 25 min (IQR 18-34). The median robotic console time and operation time were 135 min (IQR 110-161) and 225 min (IQR 197-274), respectively. Median blood loss was 365 mL (IQR 200-600). There were 11 (9.2%) patients who experienced complications (Clavien-Dindo classification Gr II). The me-dian catheter duration was 8 days (IQR 7-9), with a median of 10 days (IQR 7-11) of hospital stay. The PSA free-survival rate was 86% at a median 19 months (IQR 6-28) of follow up. Robotic radical prostatectomy using the da Vinci Single-Site platform system is safe and feasible, with acceptable outcomes.

Project description:Asymmetric septate uterus, commonly known as Robert's uterus, is an exceedingly rare uterine malformation described for the first time in 1970 by Robert H. Currently, surgery is the therapy of choice for Robert's uterus, with surgical choices ranging from laparotomy to minimally invasive surgery. In this paper, we reported that a 14-year-old girl with primary dysmenorrhea that gradually worsened three months after menarche had surgery after many imaging evaluations, and that the intraoperative diagnosis was Robert's uterus. The diagnostic and therapeutic laparo-endoscopic single site(LESS) combined with hysteroscopy surgery for Robert's uterine abnormality was shown via a step-by-step presentation of the method accompanied by narrated video footage. During the ten-month postoperative follow-up period, the patient had monthly recurrences with normal menstrual volume and no dysmenorrhea, demonstrating that as a minimally invasive treatment, LESS combined with hysteroscopy surgery is a successful methodfor diagnosing and treating this specific malformation.

Project description:Petrous bone cholesteatomas (PBCs) are epidermoid cysts, which have developed in the petrous portion of the temporal bone and may be congenital or acquired. Cholesteatomas arising in this region have a tendency to invade bone and functional structures and the middle and posterior fossae reaching an extensive size. Traditionally, surgery of a giant PBC contemplates lateral transtemporal or middle fossa microscopic surgery; however, in recent years, endoscopic surgical techniques (primary or complementary endoscopic approach) are starting to receive a greater consensus for middle ear and mastoid surgeries. We report the rare case of an 83-year-old Caucasian male affected by a giant cholesteatoma that eroded the labyrinth and the posterior fossa dura and extended to the infralabyrinthine region, going beyond the theca and reaching the first cervical vertebra. The giant cholesteatoma was managed through a combined approach (microscopic and, subsequently, complementary endoscopic approach). In this case report, we illustrate some advantages of this surgical choice.

Project description:IntroductionThe treatment of choice for mediastinal tumours is surgical, with the standard approach being sternotomy. Because of the invasive nature of this procedure, the management of these masses through mini-invasive surgery has become an alternative method.Presentation of caseWe report the case of a woman with a mediastinum tumour and a new technique used for resection, through an inframammary left incision, using a Thoratrak rib spreader and Rultract Skyhook retractor assisted by a video.Discussion/conclusionThis approach allows a complete visualization of the mediastinum and total dissection of the tumour safely around vascular and nervous structures. The pain is minimal because there is no real rib spread but instead an anterior displacement of the upper rib. This is the first reported case of resection of a mediastinum tumour by inframammary approach using a Thoratrak rib spreader and Rultract Skyhook.

Project description:Objective To review our experience in a series of patients who underwent revision endoscopic pituitary surgery. Methods Retrospective chart review. Results A total of 27 patients were included in the study. Of the 21 patients who required nasoseptal flap reconstruction, a left-sided nasoseptal flap was successfully used in 13 patients. Gross total or near-total resection of tumor was achieved in 74.1%. Cavernous sinus invasion and presentation with residual disease were identified as factors limiting extent of resection (p = 0.002 and 0.009, respectively). A statistically significant difference (p = 0.027) was noted between mean largest tumor dimension in patients with gross total resection and those with near-total or subtotal resection. Complications occurred in 22% and included postoperative temporary diabetes insipidus (n = 2), postoperative hypotension (n = 2), new anterior pituitary insufficiency (n = 1), and right-sided abducens palsy (n = 1). Conclusions Revision endoscopic pituitary surgery is advantageous but technically challenging. Cavernous sinus invasion and presentation with residual disease were significant factors limiting extent of resection. Suprasellar extension was not a factor limiting extent of resection and may prove to be an advantage over microscopic speculum-based approaches. Because of the right-sided scarring from prior surgery, a left-sided nasoseptal flap is reliable and advantageous.

Project description:Introductionand importance: Accidental ingestion of foreign bodies (FBs) is common among infants. In case of sharp FBs, the risk of accidental organ damage with potential life-threatening complications constitutes an absolute indication for removal. We present the case of a child, who, following the ingestion of an open safety pin, was successfully treated exclusively with minimally invasive techniques.Case presentationA 9-month-old male patient was admitted for hematemesis. An anteroposterior and lateral X-ray of the thorax and abdomen revealed the presence of an open safety pin in the epi-mesogastric region, without a precise localization. Upper and lower gastrointestinal endoscopy, fluoroscopy, and laparoscopy were combined in the same intervention to localize and safely remove the foreign body. The patient was dismissed on a postoperative day 1.Clinical discussion and conclusionThe two main pitfalls of this scenario were the initially uncertain location of the foreign body and the young age of the patient. A combination of different techniques was used to safely locate and remove the foreign body, reducing hospitalization and avoiding repeated radiological exposure. An experienced team in a tertiary paediatric surgical and endoscopic centre increases the chances of success and minimizes invasiveness and the risk of complications.

Project description:ObjectivesTo understand how physician ownership of ambulatory surgery centers (ASCs) relates to surgery use.Data sourceUsing the State Ambulatory Surgery Databases, we identified patients undergoing outpatient surgery for urinary stone disease in Florida (1998-2002).Study designWe empirically derived a measure of physician ownership and externally validated it through public data. We employed linear mixed models to examine the relationship between ownership status and surgery use. We measured how a urologist's surgery use varied by the penetration of owners within his local health care market.Principal findingsOwners performed a greater proportion of their surgeries in ASCs than nonowners (39.6 percent versus 8.0 percent, p<.001), and their utilization rates were over twofold higher ( p<.001). After controlling for patient differences, an owner averaged 16.32 (95 percent confidence interval [CI], 10.98-21.67; p<.001) more cases annually than did a nonowner. Further, for every 10 percent increase in the penetration of owners within a urologist's local health care market, his annual caseload increased by 3.32 (95 percent CI, 2.17-4.46; p<.001).ConclusionsThese data demonstrate a significant association between physician ownership of ASCs and increased surgery use. While its interpretation is open to debate, one possibility relates to the financial incentives of ownership. Additional work is necessary to see if this is a specialty-specific phenomenon.
