Filter by:Repair of inguinal hernia is the most common operation of the general surgeon. In recent years, it was recognized that chronic postoperative pain is as important for postoperative outcome as recurrent hernia. The incidence of pain or discomfort ranges up to 60% of operated patients. Despite the fact that laparoscopic hernia repair has been shown to reduce postoperative pain compared to open hernia repair, up to 5% of patients suffer from persistent discomfort. During that operation the mesh is either fixed using a stapler or tissue adhesive glue. With the current study we compare postoperative pain between patients undergoing laparoscopic inguinal hernia repair with either mesh fixation using a stapler or tissue adhesive. The use of von Frey monofilaments allows to describe pain with a high sensitivity.
The purpose of the present study is to investigate whether or not the use of mesh is indicated in the repair of all size umbilical hernias as to reduce the rate of recurrence. This method is regularly used in umbilical hernia reconstruction although most surgeons repair small hernias using suture repair (fascia adaptation). Especially risk factors for hernia recurrence such as hernia size and BMI > 30 kg/m2 need to be evaluated and correlated to the method of hernia repair.
The aim of this study is to compare laparoscopic total extraperitoneal and open mesh repair of inguinal hernia, with regard to hospital stay, postoperative pain, quality of life, postoperative recovery and return to daily activities, complications and recurrences
Mesh repair for open incisional hernia repair with fibrin sealant or with drainage
Hernia of the abdominal wall occur frequently after various surgical procedures of the abdomen and are increasingly performed by laparoscopic means. Different mesh fixation techniques are applied, but the influence of mesh fixation on shrinkage is not known in human patients. Therefore, mesh shrinkage was assessed using two different techniques for fixation.
Isolated Congenital Diaphragmatic Hernia (CDH) can be diagnosed in the prenatal period, and remains associated with a 30 % chance of perinatal death and morbidity mainly because of pulmonary hypoplasia and pulmonary hypertension. In addition, in the survivors there is a high rate of morbidity with evidence of bronchopulmonary dysplasia in more than 70% of cases. The risk for these can be predicted prenatally by the ultrasonographic measurement of the observed/expected lung area to head circumference ratio (O/E LHR) which is a measure of pulmonary hypoplasia. Also position of the liver is predictive of outcome. The proposing consortium has developed a prenatal therapeutic approach, which consists of percutaneous fetoscopic endoluminal tracheal occlusion (FETO) with subsequent removal of the balloon. Both procedures are performed percutaneously, there is now experience with more than 150 cases and it has been shown to be safe for the mother. We have witnessed an improvement of survival in fetuses with a predicted chance of survival of less than 30% (referred to as fetuses with severe pulmonary hypoplasia; O/E LHR <25% and liver herniation) to 55% on average. Also there is an apparent reduction in morbidity with the rate of bronchopulmonary dysplasia decreasing from the estimated rate of more than 70% to less than 40% in the same severity group. Further we have shown that results of FETO are predicted by LHR measurement prior to the procedure, so that better results can be expected in fetuses with larger lung size. Therefore we now aim to offer FETO to fetuses with moderate CDH (=O/E LHR 25-34.9%, irrespective of the liver position as well as O/E LHR 35-44.9% with intrathoracic herniation of the liver). When managed expectantly the estimated rate of postnatal survival is 55%. This trial will test whether temporary fetoscopic tracheal occlusion rather than expectant management during pregnancy, both followed by standardized postnatal management increases survival or decrease oxygen dependency at 6 months of age. The balloon will be placed between 30 and 31+6 weeks, and will be removed between 34 and 34+6 weeks.
Incisional hernia is the most frequently seen long term complication in surgery causing much morbidity and even mortality in patients. Despite studies on the optimal closing technique for laparotomies, the risk for incisional hernia after midline incision remains about 5-20 %. Major risk factors for incisional hernia after a laparotomy, like obesity, steroid use, malnutrition, smoking and connective tissue disorders, are known. Despite this knowledge, there has not yet been developed a sufficient method for prevention. One specific group of high risk patients are patients with an abdominal aortic aneurysm (AAA). The relationship between aortic aneurysm and other abdominal wall hernias, like inguinal hernias, has been reported. Retrospective and prospective studies have shown an average risk for incisional hernia after AAA repair of 31.6 %. Another high risk group is the group of obese patients. Patients with a BMI of more than 27 have a high risk of developing an incisional hernia after midline incision with an incidence of 22% after 12 months. Considering only 50 % of incisional hernia will be clinically evident in the first 12 months, the total incidence will be above 30%. This high risk group of patients with obesitas and aneurysmatic disease can benefit most from prevention. Some small studies have been performed to evaluate the usefulness and safety of primary laparotomy wound closure with the aid of prosthetic mesh. These studies show a very low risk for incisional hernias and a low infection rate, even when used in contaminated wounds such as colostomal surgery. However, there has not been performed an adequate randomized controlled trial to study the prevention of incisional hernias. Our hypothesis is that incisional hernia prevention with use of prosthetic mesh after laparotomy is effective in patients with aortic aneurysm and in obese patients with a BMI of more than 27.
The objective of this study is to assess pain that occurs following hernia repair that is related to mesh fixation. The study is designed to see if there is any difference in pain after surgery between absorbable and permanent methods of mesh fixation in inguinal and ventral hernia repair.
Laparoscopic techniques have been applied widely to the management of various common pediatric surgical diseases. Current evidence lacks sufficient quality to justify the widespread adoption of the laparoscopic approach to the repair of inguinal hernias within children. It is important to critically evaluate the efficiency and the potential risks of these new techniques before they can supplant open techniques as the treatment modality of choice. Numerous large case series of laparoscopic inguinal hernia repair have been reported with average length of stay, complication rates, recurrence rates and pain management scores that mirror those of open inguinal hernia repair. Only one randomized controlled trial has been performed to compare the open versus laparoscopic technique which has not provided answers regarding the potential benefits on young infants. Benefits of an open approach in children includes a shorter operative time, while the laparoscopic procedure is associated with less pain and a better cosmetic result. This study will compare open versus laparoscopic repairs of inguinal hernias. The primary outcome variable will be total dose of acetaminophen administered postoperatively for pain management. Secondary outcome variables include 1) Incidence of intraoperative complications such as compromise of testicular vessels, perforation of abdominal viscera; 2) Short-term outcomes such as operative time, rate of conversion from open to laparoscopic procedure, requirement for reoperation within 30 days, wound infection, acute hydroceles and post-operative length of stay; 3) Long-term outcomes such as recurrent inguinal hernia, testicular atrophy and; 4) Cost of hospitalization will be compared between the open and laparoscopic groups. Comparisons will be made in two groups of patients- patients with 1) unilateral hernias and 2) bilateral hernias and will last for 2 years. 102 patients in the unilateral arm and 50 patients in the bilateral arm will be randomized to each treatment group and each subject will be followed for up to 12 months following the surgical intervention. Two study evaluations by telephone (in addition to a single outpatient clinic visit already required as part of standard post-operative care) will be required of each research subject and his/her parent/guardian. The telephone evaluations will occur at 3 and 12 months following surgery. The standard post-operative clinic visit is scheduled at 2 weeks following surgery.
Randomized, controlled, prospective study of 54 patients receiving surgery for cancer of the lower third of the rectum with a permanent end colostomy. The aim of the study was to reduce parastomal hernia (PH) occurrence by implanting a lightweight mesh in the sublay position. Patients were followed up a) clinically and b) radiologically by means of abdominal CT. In the clinical follow-up, hernias were observed in four out of 27 patients (14.8%) in the study group and in eleven out of 27 (40.7%) in the control group (p=0.03). The implantation of the mesh reduces the appearance of PH, is well tolerated, and does not increase morbidity
