In the surgical correction of large incisional hernias, the use of a prosthesis is essential in most cases regardless of the technique chosen. The preference is for the polypropylene prosthesis.
To compare the onlay and Rives-Stoppa techniques in the correction of incisional hernias, their immediate results, complications, advantages, and disadvantages.
Two groups of patients with incisional hernias were analyzed, submitted to the onlay (19 patients) and Rives-Stoppa (17 patients) techniques, and that used polypropylene prostheses. General epidemiological variables, perioperative data variables, and postoperative complications were assessed.
The patients’ epidemiologic profile was similar between both groups. The majority were women (58.4%), with a mean age of 65.5 years and a previous mean body mass index of 41.5 kg/m². The Rives-Stoppa technique was employed in most patients (52.7%). Those submitted to the onlay technique had longer abdominal drainage time and longer hospital stay, as well as a higher incidence of seromas and surgical wound infection.
The incisional herniorrhaphy technique with the placement of a pre-peritoneal polypropylene mesh by the Rives-Stoppa technique was superior to the onlay due to lower rates of drain use, hospital stay, and postoperative complications.
Lumbar hernias are rare. Usually manifest with reducible volume increase in the post-lateral region of the abdomen and may occur in two specific anatomic defects: the triangles of Grynfelt (upper) and Petit (lower). Despite controversies with better repair, laparoscopic approach, following the same principle of the treatment of inguinal hernias, seems to present significant advantages compared to conventional/open surgeries. However, some technical and anatomical details of the region, non usual to general surgeons, are fundamental for proper repair.
To present systematization of laparoscopic transabdominal technique for repair of lumbar hernias with emphasis on anatomical details.
: Patient is placed in the lateral decubitus. Laparoscopic access to abdominal cavity is performed by open technique on the left flank, 1.5 cm incision, followed by introduction of 11 mm trocar for a 30º scope. Two other 5 mm trocars, in the left anterior axillary line, are inserted into the abdominal cavity. The peritoneum of the left paracolic gutter is incised from the 10th rib to the iliac crest. Peritoneum and retroperitoneal is dissected. Reduction of all hernia contents is performed to demonstrate the hernia and its size. A 10x10 cm polypropylene mesh is introduced into the retroperitoneal space and fixed with absorbable staples covering the defect with at least 3-4 cm overlap. Subsequently, is carried out the closure of the peritoneum of paracolic gutter.
This technique was used in one patient with painful increased volume in the left lower back and bulging on the left lumbar region. CT scan was performed and revealed left superior lumbar hernia. Operative time was 45 min and there were no complications and hospitalization time of 24 h.
As in inguinal hernia repair, laparoscopic approach is safe and effective for the repair of lumbar hernias, especially if the anatomical details are adequately respected.
Obesity changes the anatomy of the patient. In addition to the aesthetic change, the high percentage of fat determines evident functional changes. Anthropometric normality in measuring abdominal circumference and height can serve as a basis for measuring cardiometabolic risks of obesity.
To verify if it is possible to determine parameters of normality between waist and height in people with normal BMI and fat percentages, to serve as a basis for assessing risks for obesity comorbidities.
A sample of 454 individuals with BMI and percentages of fat considered within the normal range was extracted. It was divided into age groups for both men and women between 18 and 25; 26 to 35; 36 to 45; 46 to 55; 56 to 65. A total of 249 men and 205 women were included.
Regarding the percentage of height as a measure of the abdominal perimeter, the total female sample had an average of 44.2±1.1% and the male 45.3%+1.5. For women, this percentage determined the equation of the waist-height ratio represented by X=(age+217) / 5.875, and for men X=(age+190.89) / 5.2222. “X” represents the percentage of the height measurement so that the individual falls into the category of adequate percentage of fat and BMI.
Between the stature of adult men and women with normal fat percentage and BMI, there is a common numerical relationship, with is on average 44% for women and 45% for men.
