The Effect of the Mode of Delivery to the Pelvic Floor Function
IncontinencePelvic Organ ProlapseThe childbirth is one of the risk factors for pelvic organ prolapse. In order to prevent the pelvic organ prolapse, the physicians do not routinely advice any exercises after deliveries. The investigators wondered if the mode of deliveries such as ceserean section, vaginal route delivery with episiotomy or vaginal route delivery without episiotomy effect the pelvic floor function differently or not. In order to evaluate this, the investigators are planning to measure the muscle tonus in primiparous women.
Patient Specific Mitral Valve Modeling for Surgical Planning and Training
Mitral Valve ProlapseMitral Regurgitation1 moreMitral valve disease is a common pathologic problem occurring in approximately 2% of the general population but climbing to 10% in those over the age of 75 in Canada[1]. This project has three primary goals all of which will positively affect cardiac patient care. 1) Create patient specific MV models for complex repairs that will allow surgeons the opportunity to practice the repair. 2) Potentially predict the outcomes following minimally invasive repair techniques such as transcatheter treatments (e.g., MitraClip). 3) Provide a model to train individuals on mitral valve repair techniques.

Pelvic Organ Prolapse RecurrenceBased on a prospective study, to evaluate how pre-operative pelvic floor status - the presence of injury to the musculus levator ani - may influence the results of laparoscopic sacrocolpopexy. The investigators hope to confirm or disprove the hypothesis that the presence of such injury increases the risk of post-operative prolapse recurrence
Comparison Between Two Types of Meshes Used in Pelvic Organs Prolapse Procedures
Postoperative ComplicationsUsing partially absorbed meshes in pelvic reconstructive surgery will involve fewer postoperative complications especially less pain caused by the mesh mass.
Post-operative Voiding Dysfunction: the Preferred Method for Catheterization
Voiding Dysfunction After Pelvic Organ Prolapse SurgeryThis study is divided into two parts. The first part is a prospective observational study of patients undergoing pelvic organ prolapse (POP) surgery. The goal is to determine patient preference between 3 different methods of bladder drainage in case of post-operative voiding dysfunction (POVD): transurethral indwelling catheterization (TIC), clean intermittent self-catheterization (CISC), and suprapubic tube (SPT). The second part of the study will be for those that choose CISC as their preferred method, whereby these patients will be randomized to receive CISC instruction either pre- or post-operatively to determine whether there is a difference in overall patient satisfaction based on timing of teaching. The investigators hypothesize that patients that receive informed consent pre-operatively will favour the use of SPT over TIC and CISC to manage potential POVD. Among those patients who opted for CISC in management of their post-operative voiding dysfunction, patients that are taught how to perform CISC pre-operatively in the clinic will have a higher level of satisfaction compared to those that are taught post-operatively in the hospital.
Pelvic Floor Study: Biomechanical Properties of the Female Pelvic Floor
Pelvic Organ ProlapsePelvic floor dysfunction in the form of pelvic organ prolapse or urinary and fecal incontinence is a sequela for some women who experience injuries during birth. It affects adult women of all ages. The life time risk for women by age of 80 years for undergoing surgical correction is shown to be 11.1 % , and 29 % of them will undergo re-operation for recurrences later on. Still, even today the biomechanics of the pelvic floor is not understood enough. The aim of our study is to investigate the biomechanical properties of the female pelvic floor, i.e. the vaginal wall, by means of clinical, sonomorphometric (ultrasound), histological and elastomechanical examinations. In principle, the elasto-mechanical properties of the vaginal wall will be examined by the new and innovative so called aspiration device, developed at the Eidgenoessische Technische Hochschule (ETH) Zurich, Switzerland. This tool generates a low-pressure of -25 mbar at the vaginal wall, aspirating it under visual control by aid of an integrated video camera and therefore allowing to measure the difference of its convexity under aspiration and at rest. In case of prolapse surgery, this allows us to take a biopsy of the measured vaginal wall and analyze it at the Institute of Anatomy at the University of Zurich-Irchel by means of histological (e.g. connective tissue, extracellular matrix) and molecular biological examination. With an increasing elderly population, more and more women will need surgery for pelvic organ prolapse. While effective in restoring anatomy, sometimes by aid of meshes made out of polypropylene, the functional outcomes and quality of life are not always restored satisfactorily. This interdisciplinary project intends to add a contribution to this for our patient still bothersome situation and to help to detect risk factors for developing pelvic floor dysfunction.
The Immune Reactivity of Biofilms in Vaginal Mesh Erosion.
Uterine ProlapseUrinary Incontinence1 moreAging, birth trauma and extensive pelvic surgery are the causes known to cause advanced pelvic organ prolaspe, fecal as well as urinary incontinence. Surgical treatment is the last resort to manage the above-mentioned clinical manifestations of pelvic floor disorders except the subject is too frail to receive operation. In order to improve the outcome of reconstructive pelvic surgery, reinforcement with synthetic mesh or biological material is the modern trend in pelvic repair. Unfortunately no prosthesis including synthetic or biological is ideal because vaginal erosion with mesh extrusion which is the subject of this protocol and other complications were reported continuously. As per the literature, the rate for mesh vaginal extrusion ranged between 2.4 and 17% when polypropylene which is the most popular synthetic material used for the mid-urethral sling or pelvic reconstructive surgery to date. The causes of this complication are still controversial which include rejection, poor quality of tissue, surgical artifact, material of mesh and etc. A prospective controlled study for the investigation of the cause for mesh vaginal erosion was conducted and the results revealed evidences of immune reactivity after mesh implantation, albeit the evidence was not solid (Am J Obstet Gynecol 2004; 191(6): 1868-1874 ). As per the pilot study initially done by us to determine the biofilm-related-infection, we have found bacterial biofilm could adhere to surfaces and interfaces, i.e. bacteria located in the cells just beneath the contacting surfaces in the electron microscopic (EM) analysis. In addition, soon after bacteria infection, proteins in biofilm undergo conformational changes, making them immunogenic and triggers a typical inflammatory response leading to activation of the complement system. Thus, we plan to use CD (clusters of differentiation) antigens - 4, 8, 20, 25, 40, 68 and quantitative analysis of FoxP3 to determine the function of regulatory T cells in the immune response. In addition, bacterial culture and EM analysis of the excised mesh with surrounding vagina tissue will be performed for further analysis of biofilms.

Colon CancerColon Polyp6 moreThe purpose of this study is to evaluate the safety and feasibility of using the Single Port (SP) robot (daVinci, Intuitive Surgical) to perform single port robotic colon surgery and transanal robotic surgery. The hypothesis of the study is that the SP robot will prove a safe effective modality to perform these procedures.
