Filter by:Congenital diaphragmatic hernia (CDH) occurs when the diaphragm, the muscle that separates the chest cavity from the abdominal cavity, does not form properly. When an opening is present in the diaphragm, organs that are normally found in the abdomen can move up into the chest cavity. The primary objective of this study is to generate information about the hereditary basis of congenital diaphragmatic hernia and abnormal lung development. Our long-term goal is to identify ways to treat babies in utero with effective but safe drugs to speed up lung development before birth.
The aim of this study was to analyze the shrinkage of two different screens in the repair of inguinal hernias in men . 32 patients with unilateral inguinal hernia were assigned randomly. A Lichtenstein tension-free hernia repair was accomplished by emplacing heavy weight versus ultralight weight polypropylene meshes for repair of incisional hernia, marked next to the lips with six titanium clips (LT200).
This is a new inguinal hernia repair technique.
Analysis of collagen subtype subcutaneously and genetic analysis of patients from families with a tendency to hernias. Furthermore circulating biomarkers and biomarkers extracted from the subcutaneously tissue such as MMP's (matrix metallo proteinases) and TIMP's (tissue inhibitor of metallo proteinases) will be measured.
The investigators are performing a genetic study of patients with multiple hernias (at least 3 primary hernias) versus a healthy control group. This genetic information is compared with circulating and subcutaneously biomarkers such as matrix-metalloproteinases (MMP's). The hypothesis is that patients with multiple hernias have different expression of specific genes compared to the healthy control group.
The goal of this study is to identify genes that convey susceptibility to congenital diaphragmatic hernia in humans. The identification of such genes, and examination of their structure and function, will enable a delineation of molecular pathogenesis and, ultimately, prevention or treatment of congenital diaphragmatic hernia. There are many different possible modes of inheritance for congenital anomalies, including autosomal dominant, autosomal recessive, and multifactorial. Multi-factorial inheritance is responsible for many common medical disorders, including hypertension, myocardial infarction, diabetes and cancer. This type of inheritance pattern appears to involve environmental factors as well as a combination of genetic variations that together can predispose to or produce congenital anomalies, such as congenital diaphragmatic hernia. Our study is designed to establish a small, well-defined genetic resource consisting of 1) Nuclear families suitable for linkage analysis by parametric,non-parametric (e.g. sib pairs, TDT) and association techniques, 2) Individuals with congenital diaphragmatic hernia who can be directly screened for allelic variation in candidate genes, and 3) Individuals who can serve as controls (are unaffected by congenital diaphragmatic hernia). Neonates and their families will be collected from homogenous and heterogeneous populations. By characterizing diverse populations, it should be possible to increase the likelihood of demonstration of genetic variation in selected candidate genes that can then be used in association and linkage studies in individual subjects with congenital diaphragmatic hernia.
The purpose of this study is to determine if the device is supplying sufficient diagnosis results of an internal rectal prolapse, of a pelvic floor ptosis and for the determination of an interal hernia into the Douglas pouch, as well as to determine the technical success of using the device at the patient.
Laparoscopic inguinal hernia repair (LIHR) has got comparable results in comparison to open hernia repair (OHR). Many studies have shown that LIHR gives similar results in terms of recurrence as compared with OHR but with the added advantage of less chances of post operative, pain, wound infection and early return to activity. LIHR was started using the transabdominal preperitoneal (TAPP) approach. Another technique of LIHR that has evolved is totally extra peritoneal (TEP) repair. There is only one study of 52 patients comparing TAPP with TEP repair and thus there is insufficient information as to which of the 2 techniques is better. Therefore, we have designed the present study to compare the transabdominal preperitoneal (TAPP) technique with totally extra peritoneal (TEP) technique of laparoscopic inguinal hernia repair. The advantages of TEP may include - no breach of peritoneum so less risk of bowel injury and post-operative adhesions. We will be using a modified technique of TEP repair where we will not use tacker to fix the mesh to reduce the cost of the procedure. On the other hand, TAPP is easy to perform and probably better for irreducible hernia. There is no such comparative study reported in the literature. We have been performing both TAPP and TEP procedures for hernia repair regularly in the department. RESEARCH HYPOTHESIS: TEP repair of inguinal hernia is better than TAPP repair in terms of reduced cost and avoidance of peritoneal incision. OBJECTIVE: To compare the Transabdominal preperitoneal (TAPP) vs. Totally extra peritoneal (TEP) techniques of laparoscopic inguinal hernia repair.
Background: Large acceptance of mesh reinforcement techniques in groin hernia repair lowered recurrence rates for all techniques. Recurrence rate alone is not the main quality criterion for hernia repair anymore. Chronic significant post operative pain is a common, clinically relevant, poorly understood and poorly studied entity which is 3 to 5 times more common than hernia recurrence. As a subgroup to chronic significant post operative pain or as a separate entity, sexual dysfunction due to ejaculatory and genital pain after inguinal hernia repair may happen in approximately 2.5% of patients. Patient's preoperative psychological profile as well as pain exposure history is showed to be important in the development of chronic significant post operative pain. The objective of this study is to analyse chronic significant post operative pain and the functional outcome status of patients after laparoscopic repair compared to open repair. Methods: A randomized controlled non-blinded clinical trial is designed to compare open inguinal hernia mesh repair with laparoscopic totally extraperitoneal repair on chronic significant post operative pain, pain related sexual function disorders, complications, health related quality of life outcomes, recurrence rates, and cost. Volunteers will be recruited in Geneva University Hospital, department of surgery, visceral surgery unit. Eligibility criteria is male patient aged over 21 years, with reducible inguinal unilateral or bilateral primary hernia who are candidates for elective surgery and medically fit for general anesthesia.130 patients will be enrolled for each group to achieve an α-Level of 0.05 and a power of 80%. Follow-up will take place at 10th, 30th days as well as 3 12 and 24 post operative months by questionnaires and by clinical exam by independent expert. An overall cost-analysis will be realized. Patient enrollment in the study will start in April 2008 and estimated to end in may 2009.
Background: Midline incisional hernia is reported from 0,5 to 11% after abdominal operations. Primary repair without mesh reinforcement is almost abandoned because of high recurrence rates (24 to 46%). Use of prosthetic mesh in incisional hernia repair lowered the recurrence rates under 10%. Recurrence rate alone is not the main quality criterion for incisional hernia repair anymore. Large series and meta-analyses confirmed the value of laparoscopic repair as at least equal if not better compared with open repair. Discomfort, pain, diminished quality of life and body image alteration influences functional well being. No baseline information exists in any of these fields treating pre- or post-operative phases in patients with incisional hernia. Respiratory functions and medico-economic evaluation are other rarely investigated fields that we consider in our trial. The objective of this study is to analyse the functional outcome status of patients after laparoscopic incisional hernia repair compared to open repair. Methods: A randomized controlled non-blinded clinical trial is designed to compare laparoscopic incisional hernia mesh repair with open repair on post operative pain, health related quality of life outcomes, body image and cosmetic measurements, respiratory functions, recurrence rates, and cost. Volunteers will be recruited in Geneva University Hospital, department of surgery, visceral surgery unit. Eligibility criteria is male patient aged over 18 years, with reducible incisional hernia who are candidates for elective surgery and medically fit for general anesthesia.30 patients will be enrolled for each group. Follow-up will take place at 10th, 30th days as well as 3 12 and 24 post operative months by questionnaires and by clinical exam by independent expert. An overall cost-analysis will be realized. Patient enrollment in the study will start in April 2008 and estimated to end in september 2009.
