[Synthetic prostheses used in surgery to repair abdominal wall defects (excluding groin hernias). Characteristics, in situ behaviour and applications].

This study is an updating on synthetic prostheses used today to repair incisional hernias, eviscerations and abdominal wall defects due to a severe infection or a parietal excision of malignant tumours. The present prostheses are the fruits of the constantly developing plastic industry. Their characteristics and types (mesh or patch), together with the materials they are made of, are studied taking this development into account. The tissular reactions caused by prostheses are different depending on whether the material they are made of is an absorbable one or not. Published data on animal experimentation are largely used in this part of the study. A significant part is also allocated to the pathobiology of prostheses infection on which is based prevention of risk infection in the surgical practice. A synthetic prostheses has to be chosen depending on its characteristics and the tissular reactions it generates. In a septic environment, only absorbable prostheses can be used without risk. As for incisional hernias, which allows the authors to refer to their own expérience, the choice also depends on both the surgeon's own conception of the treatment and its purpose. The defect recovery after parietal excision of malignant tumours is eased by the use of a synthetic prostheses. In the future, synthetic prostheses will be even more used than today in the repair of abdominal wall. A present, the materials they are made of keep on being developed.

Anatomical considerations for surgery of the anterolateral abdominal wall.

Closure of large incisional hernias with the Components Separation Method (CSM) could be explained by medial-caudal rotation of the internal and transverse oblique muscles around their centres of origin. In eight human cadavers, the CSM was performed, and translation of the rectus abdominis muscle was measured. Mean unilateral translation of the rectus abdominis in the lateral-medial direction measured 2.2, 3.7, and 3.5 cm. This was 2.7, 4.5, and 4.0 cm after release of the posterior rectus sheath. Mean translation in a caudal direction was 0.5 cm, but seven cadavers showed a mean translation of 1 cm of the uppermost measuring point in a cranial direction. The hypothesis that rotation of separate tissue layers of the abdominal wall largely accounts for the translation effect of the CSM must be rejected. Release of the external oblique muscle produces more benefit to abdominal wall closure than release of the posterior rectus sheath.

Abdominal wall reconstruction after open management of the septic abdomen.

The increasing popularity of open management of the septic abdomen has generated a challenge that the surgeon is forced to face more frequently. The typical presentation is that of a patient with a full-thickness abdominal wall defect occurring after a protracted, severe illness. The various methods of reconstruction of the abdominal wall are reviewed and evaluated. The reconstruction should only be attempted once intra-abdominal sepsis is controlled, re-exploration of the peritoneal cavity is no longer necessary and organ support is discontinued. Although various methods of reconstruction are described, the recommended technique consists of either medial advancement of the rectus abdominis muscle or direct application of split-thickness skin grafts. Mid-line abdominal defects may also be repaired with tensor fasciae latae or rectus femoris flaps.

The vascular anatomy of the lower anterior abdominal wall: a microdissection study on the deep inferior epigastric vessels and the perforator branches.

The deep inferior epigastric artery provides the main blood supply to the lower abdominal wall. Microdissection of the artery, its main branches, and the perforator vessels was undertaken in 20 cadavers. The artery was found to be associated with two veins in most of the cases (90 percent). The lateral division of the deep inferior epigastric artery and the perforator vessels it gives are more dominant (80 percent of cases) than the medial perforators (20 percent of cases). The lateral perforators were greater in number (80) and more consistent than those that arose from the medial division (28). The musculocutaneous perforators are the most important perforators supplying the anterior abdominal wall. An average of 5.4 large perforators (>0.5 mm in diameter) were dissected in each case. These perforators are mostly contained in the area lying laterally and below the umbilicus, with an average distance of 4 cm from the umbilicus. The musculocutaneous perforators may have a direct or indirect course. Larger perforators (>0.5 mm in diameter) were found to have a direct course through the subcutaneous fat to the skin. Smaller perforators do not reach the skin but terminate at the level of the deep fat layer by branching after piercing the rectus sheath. The direct perforator vessels with their associated veins (microdissection) keep a consistent diameter before dividing at the subdermal level and end by contributing to the subdermal plexus.

Evaluation of cutaneous abdominal wall sensibility after abdominoplasty.

Changes in cutaneous sensibility are common after diverse plastic surgical procedures. Although prior studies examined aesthetic results, combined procedures, and new abdominoplasty techniques, few examined the effect of undermining on cutaneous sensibility. This study aimed to analyze and quantify cutaneous sensibility after classic abdominoplasty. Two groups of patients were studied: a control group of 10 patients without surgery and another group of 25 patients who had undergone classic abdominoplasty. The abdominal wall surface was divided into nine regions. Pain sensibility was evaluated by tests with needles, and thermal sensibility by test tubes containing hot and cold water. Superficial tactile sensibility was tested using the Pressure-Specified Sensory Device (PSSD), which is capable of determining the cutaneous pressure threshold. Statistical analysis was conducted using Student's 't-test'. The results showed a decrease in the three types of sensibility. Statistical analysis showed a significant difference (p < 0.05) between the groups for all regions tested. The centermost regions of the abdominal wall presented the highest index of analgesia and thermal anesthesia, as well as higher cutaneous pressure thresholds.

Enoxaparin associated with hugh abdominal wall hematomas: a report of two cases.

Enoxaparin is a low-molecular-weight heparin used for prophylaxis against deep venous thrombosis. Indications include hip and knee replacement surgery, risk of deep venous thrombosis during abdominal surgery, and prevention of ischemic complications of unstable angina and non-Q-wave myocardial infarction. Its efficacy in the prevention of the above complications has been previously studied; however, the liberal use of enoxaparin is not without incident. Complications of enoxaparin include hemorrhage, thrombocytopenia, and local reactions. Since 1993 there have been more than 40 reports of epidural or spinal hematoma formation with the concurrent use of enoxaparin and spinal/epidural anesthesia or spinal puncture. Herein reported are two cases of abdominal wall hematomas in patients receiving prophylaxis with enoxaparin. Both patients sustained an unexplained fall in the hematocrit and abdominal pain. A CT scan confirmed the diagnosis. One patient recovered uneventfully; however, the other patient, on chronic hemodialysis, became hemodynamically unstable and hyperkalemic and sustained a fatal cardiac arrhythmia. An extensive review of the literature revealed no similar cases of abdominal wall hematomas associated with enoxaparin although other complications, including spinal and epidural hematomas, psoas hematomas, and skin necrosis have been reported. The extended use of enoxaparin as an anticoagulant requires the physician to be vigilant of these rare complications. Bleeding can occur at any site during therapy with enoxaparin. An unexplained fall in the hematocrit or blood pressure should lead to a search for a bleeding site.

Infiltration of the abdominal wall with local anaesthetic after total abdominal hysterectomy has no opioid-sparing effect.

We have measured the effect of infiltration of the deep and superficial layers of the abdominal wound on morphine consumption and pain for 48 h after operation, in 40 patients undergoing total abdominal hysterectomy, in a double-blind randomized study. Patients received wound infiltration with 0.9% normal saline 40 ml or 40 ml of 0.25% bupivacaine with epinephrine 1:200,000. There were no significant differences between groups in morphine consumption, linear analogue scores for pain at rest or on movement, nausea or sedation during the first 48 h after operation. We conclude that infiltration of the deep and superficial layers of the wound of a Pfannenstiel incision with local anaesthetic solution did not confer additional analgesia in patients undergoing major gynaecological surgery.

Abdominal wall endometriomas: report of eight cases.

Eight cases of abdominal wall endometrioma were encountered in seven patients from February 1994 through April 1996. The age of the patients ranged from 19 to 36 years, with an average age of 32.8 years. Ten abdominal procedures had been performed on these patients before the diagnosis of endometrioma: six cesarean sections, two diagnostic laparoscopies, one total vaginal hysterectomy, and one ventriculoperitoneal shunt. Symptoms occurred from 6 months to 10 years after their previous surgery. Only one patient had a prior diagnosis of endometriosis. The most common presentation was a cyclic painful abdominal mass. The differential diagnosis included endometrioma in four (50%) of the cases. Diagnostic tests used for preoperative evaluation included ultrasound, fine-needle aspiration, and computed tomography. All patients underwent wide local excision. There was one recurrence, requiring re-excision at 22 months postoperatively. The pathogenesis, diagnosis, treatment, and recent literature are discussed.

[Large abdominal parietectomy for late abdominal wall recurrence of colonic cancer: reconstruction with latissimus dorsi free flap with delayed insertion].

Parietal recurrence following conventional treatment of colorectal cancer is an infrequent event and is usually associated with an intra-abdominal recurrence. The study aim was to report a large solitary abdominal wall recurrence observed 80 months after the resection of a sigmoid adenocarcinoma and treated by a left hemiparietectomy associated with a segmental colectomy. The abdominal wall reconstruction combined a prosthesis and a latissimus dorsi myocutaneous free flap with delayed insertion after initial transfer.

Detachment of the continent ileostomy poucn from the anterior abdominal wall: report of two unusual cases.

The cases of two patients with continent ileostomies are presented. These illustrate the problems encountered with detachment of the pouch from the abdominal wall resulting in angulation of the efferent loop of the pouch in relation to the nipple valve and difficulty intubating the pouch. Both patients required operative correction of the separation. Several suggestions are made in order to prevent or decrease the incidence of the complications. Removal of a peritoneal strip around the efferent loop of the pouch appears to facilitate adequate fixation of the pouch to the anterior abdominal wall.

Rapid prenatal diagnosis of Patau's syndrome in a fetus with an abdominal wall defect by 72 hour culture of cells from amniotic fluid.

A woman in the 32nd week of pregnancy was referred for investigation because of fetal abnormalities, including an abdominal wall defect, detected by ultrasonography. In view of the increased risk of chromosome abnormality, amniocentesis was performed to enable informed decisions about the management of the pregnancy and delivery to be taken. Cells from the liquor were inoculated into standard lymphocyte culture medium and incubated for 72 h. Slides with a high mitotic index and good quality metaphases, comparable to those from a blood culture, were obtained after harvesting. Cytogenetic analysis showed the karyotype to be 46,XY, - 14,+t(13q14q), which is consistent with Patau's syndrome. This technique appears to be an option for rapid karyotyping in cases of abdominal wall defect, where a chromosomal abnormality is suspected.
