Active clinical trials for "Hernia"

Incisional hernia is a common complication in visceral surgery and varies between 11 and 26% in the general surgical population. Patients requiring emergency laparotomy are at high risk for the development of incisional hernia and fascial dehiscence. Among this population the incidence of incisional hernia in patients undergoing emergency surgery varies between 33-54%. Incisional hernias are associated with a high morbidity rate, such as intestinal incarceration, chronic discomfort, pain, and reoperation and typically require implantation of a synthetic mesh in a later second operation. Fascial dehiscence represents an acute form of dehiscence and has been observed in up to 24.1% and is associated with a mortality rate up to 44%. The gold standard for abdominal wall closure during elective and emergency operations is a running slowly absorbable suture. In the elective situation it has been shown that prophylactic mesh implantation in high risk patients reduced the incidence of incisional hernia significantly. The investigators and others have shown that mesh implantation in patients undergoing emergency laparotomy or in contaminated abdominal cavities are safe . With a randomized controlled trial the investigators now aim to compare the incidence of incisional hernia after prophylactic mesh implantation versus standard of care in patients requiring emergency laparotomy.

This is a prospective multicenter study of patients diagnosed with a medium to giant incisional hernia (transverse defect >7 cm). Patients referred to the surgical outpatient clinic are invited to participate in the study. As a standard, all patients who are examined for incisional hernia undergo CT scan according to a hernia protocol, before planning of surgical repair (baseline scan). After this CT scan, patients are seen in the out-patient clinic once again and either treated conservatively without surgery, or scheduled for elective surgical repair of the hernia. If surgery is planned, the patients participating in the study undergo an additional CT scan in hernia protocol, within two weeks prior to surgery (follow-up scan). If a conservative non-surgical approach is chosen, patients can still participate in the study and will undergo an additional CT scan after 28-32 weeks.

It´s a pilot study, randomized, realized in the Central Hospital "Dr. Ignacio Morones Prieto", SLP, Mexico. Hypothesis: The polyethylene mesh is secure in open ventral repair.

To determine if there is a difference in the quality of life in between patients who undergoes laparoscopic transabdominal pre-peritoneal (TAPP) or modified Lichtenstein hernioplasty

Aim of the work In this study, we will evaluate posterior Evaluation of posterior component separation modified TAR technique "Transversus Abdominids Release" in the treatment of parastomal hernia. The primary outcome will be recurrence while the secondary outcome will be infection, postoperative complications (bleeding and dehiscence), pain score, operative time, hospitalization, need for drain, time for drain removal and pulmonary function test before and after surgery

Lichtenstein technique, inserting a mesh over the inguinal cord in the neurological plane, is considered the standard of inguinal hernia repair, but it has 4% recurrence and 12% chronic postoperative pain. Rives technique inserts the mesh in the preperitoneal space behind the neurological plane and the muscular plane, thus better fulfilling the principle of hydrostatics.

Prospective randomized prospective interventional study with 40 consecutive patients for whom surgical treatment for PH was indicated and who are in postoperative follow-up with the Oncology Surgery group of the Department of Digestive Tract Surgery and Coloproctology, Faculty of Medicine, University of São Paulo . The free and informed consent form will be applied to the patient by the researchers in two copies of equal content and after any doubts related to the research are resolved, the patient will sign the copies together with the researcher. At any time, the patient may opt out of the study. The contacts of the researchers and the institution will be fully available to the research subject to resolve doubts and for any eventuality that may occur.

The European Hernia Society Guidelines of 2018 suggest that laparoscopic surgery should be preferred over open surgery for bilateral inguinal hernia repair even though scientific evidence are scarce. We will conduct a prospective, non randomise control trial, to investigate the superiority of one technique over the other.

Repairing of emergency (strangulated) abdominal wall hernias with mesh may cause infective complications.

The incidence of port-site hernia in patients with risk factors (obesity, elderly, diabetes and lung disorders) can be reduced by the use of a prophylactic mesh in the closure of umbilical port site.
