[Repair of large defects of the abdominal wall with lyophilized dura mater. Experimental research (author's transl)].

In order to evaluate whether and how far lyophilised human dura mater deserves to be preferred in repair surgery of large defects of the abdominal wall, the Authors present and discuss the results they obtained during the course of experimental research. In the light of personal histological documents, they stress the absence of reject phenomena and the peculiar capacity of the prosthesis for substitution by cicatricial tissue, properties which, together with the complete re-epithelialisation of the peritoneal mesothelium and the resistance to mechanical stresses, evidence that lyophilised dura mater must rightly be given preference in plastic reconstruction of large defects of the abdominal wall.

Abdominal wall actinomycosis associated with an IUD. A case report.

Abdominal wall actinomycosis without pelvic organ involvement in users of intrauterine contraceptive devices (IUDs) has not been reported on previously. We encountered one such patient, whose uterine cervix was colonized superficially with Actinomyces. We suggest that systemic actinomycosis be included in the differential diagnosis of pain in IUD users when Actinomyces is found on Papanicolaou smears or in endocervical curettings. Such patients should be treated with appropriate antibiotic therapy, especially prior to any surgical intervention.

Reconstruction of abdominal wall and mons pubis in females with bladder exstrophy.

We report on 3 patients with bladder exstrophy who had considerable scar deformities of the lower abdomen after primary closure of the bladder and/or urinary diversion. The scar tissue was excised, and augmentation of the abdominal wall and mons veneris was achieved by the use of a pedicled, vascularized groin flap with integrated bone from the iliac crest. This procedure is recommended for patients with faulty closure of the pelvic ring and severe defect of the lower abdominal wall.

[New method of abdominal wall incision in autopsy].

The incision of the anterior abdominal wall proposed by the author is begun (after dissection of thoracic tissues on the median line) from processus xyphoideus sterni and led toward left regio iliacae (on the straight line or first on the left regio hypogastricae to its middle, then on liniae pararectalis) approximately till the middle of ligamentum Pouparti. Then from the lower end of this incision a transversal incision of superpubica is made at an angle, about 4--6 cm above simphysis ossium pubis, in adults 15--20 cm long. This incision provides a wide access to the organs of the small pelvis, demonstration of their changes on the spot, goes aside from median wounds or scars, and permits to penetrate from the transversal incision along the subcutaneous cellular tissue to the organs and tissues of regio subpubica.

[Traumatic abdominal-wall hernia in childhood].

In recent years an increased occurrence of posttraumatic abdominal-wall hernias, i. e., subcutaneous abdominal ruptures, has been observed in children. The causal trauma is a fall on a scooter or bicycle handlebar. The predilectional place of injury lies near the linea alba or lateral of the rectus sheath. After several days of observation in order to exclude the possibility of an additional intra-abdominal injury, the hernial gap is operatively closed. An important safety measure would be remodelling bicycle bars.

Cellulitis and necrotizing fasciitis of the abdominal wall in pediatric patients.

Soft tissue infections of the abdominal wall in 14 children were classified as cellulitis (8), necrotizing fasciitis (5), or myositis/myonecrosis (1). These 3 categories were characterized by increasing anatomic depth of infection, clinical severity, and need for more radical surgical treatment. Ten of the 14 children were neonates. The most frequent associations were omphalitis (5), necrotizing enterocolitis (4), and urachal anomalies (3). The severest infections were usually polymicrobial and contained both aerobic and anaerobic bacteria. Important clinical findings in children with necrotizing fasciitis and myositis/myonecrosis were tachycardia, systemic toxicity, severe edema, and, in older children, pain out of proportion to the apparent degree of infection. None of the children had fever or crepitation of the wound. An ominous sign, indicative of the need for immediate, radical debridement was the appearance of a patch of dusky or gangrenous skin. There were two deaths associated with delayed diagnosis of necrotizing fasciitis. One child did not receive radical debridement, and the other received it too late to be of benefit. Although these infections are rare in children, their lethal potential and early diagnostic signs must be recognized.

Abdominal wall and inguinal hernias in continuous ambulatory peritoneal dialysis patients.

This retrospective analysis of 140 continuous ambulatory peritoneal dialysis patients followed during a 4 year period revealed a 5 percent incidence of abdominal wall hernias. Inguinal hernias were frequently manifested as unilateral scrotal swelling. Hernias too small to be appreciated by physical examination were easily demonstrable with intraperitoneal instillation of technetium 99m sulfur colloid through the continuous ambulatory peritoneal dialysis catheter. This procedure was also useful when differentiating dialysate leaks from inguinal hernia in the early and late postoperative periods. Recurrences developed in 27 percent of the herniorrhaphies. Factors contributing to the development of abdominal wall hernias in continuous ambulatory peritoneal dialysis patients include uremia, obesity, anemia, and chronically elevated intraperitoneal pressures.

[Abdominal wall prostheses. Biomechanic and histological study].

The best prosthetic material is one which provides the best mechanical resistance with the best biological tolerance. In order to assess the mechanical and histological properties of abdominal wall prostheses, we performed experimental tests in animal models comparing four materials: polypropylene, dacron, polyglactine 910 and a dacron-polyglactine 910 composite. One hundred thirty rabbits were used including 10 controls and 120 test animals. A medial laparotomy was closed with an antemuscular aponevrotic prosthesis in the test animals. Animals were sacrificed at one, two and three months after the operation. Abdominal wall and prosthesis samples were tested to determine resistance to pressure and extension, deformability and elasticity. Histology tests were also done to determine resistance quality and biological tolerance. Dacron was tolerated best and was less resistant than polypropylene, though resistance was satisfactory. There was no advantage with polyglactine compared with non-resorbable prostheses; its only indication would be a septic site. The composite material tested had a resistance comparable with that of dacron but was less well tolerated.

Intermittent edema of the upper and lower extremities and the abdominal wall caused by membranous stenosis of the superior vena cava and membranous obstruction of the inferior vena cava.

We report on a 38-year-old patient with intermittent edema of the lower legs, arms and abdominal wall. The cause for his tendency to develop edema was a membranous obstruction of the inferior vena cava and a membranous stenosis of the superior vena cava. The etiology of these anomalies of the vena cava suggests a congenital malformation. In consideration of the cases of inferior and/or superior vena cava-anomalies published to date the patient received an anticoagulant therapy (coumarin) and treatment with graduated compression stockings. He now complains from time to time of a sensation tension in the lower legs after prolonged standing or sitting. Edema of the upper and lower extremities and the abdominal wall have disappeared.

Accuracy of viscera slide detection of abdominal wall adhesions by ultrasound.

Viscera slide is the normal, longitudinal movement of the intraabdominal viscera caused by respiratory excursions of the diaphragm. By detecting areas of restricted viscera slide, ultrasonic imaging was used to identify anterior abdominal wall adhesions prior to laparotomy or laparoscopy. Transcutaneous ultrasound examination was performed on 110 patients. A prediction of adhesions was made for each patient and then compared to the findings during subsequent laparotomy or laparoscopy. Only patients with previous abdominal surgery or history of peritonitis demonstrated adhesions. Sensitivity and specificity of viscera slide ultrasound in predicting adhesions were 90% and 92%. Nine out of 10 false results involved misinterpretation of ultrasound images of the lower one-third of the abdomen. Ultrasonic imaging of viscera slide is highly accurate in detecting abdominal wall adhesions. This technique is most useful in guiding the insertion of trocar in laparoscopic surgery, and as a noninvasive method in studying the formation of adhesions.

Studying the visceral physiology of tadpoles through their naturally transparent abdominal walls.

We propose using anuran tadpoles with naturally transparent abdominal skin to study the visceral physiology of amphibian larvae under microgravity. The transparency of the abdominal wall in certain tadpoles enables one to evaluate the basal physiological state and temporal changes in viscera from their movements without any invasive treatment. In order to validate our experimental design, the intestinal motility and heart rate of Rhacophorus tadpoles were examined as indices of physiological responses to stepwise changes in temperature.

Mechanism of Abdominal Wall Recurrence After Laparoscopic Resection of Colonic Cancers.

Although abdominal wall recurrence after conventional resection for colon cancer remains a rare event, several reports of trocar site recurrence after laparoscopic oncological procedures have been reported. Although the mechanism is unclear, it appears that local factors are important for trocar recurrence after colorectal cancer procedures. Hematogenous dissemination to the trocar site does not appear to be a primary mechanism. The full realization of port-site recurrence has yet to be uncovered because only a relatively small number of colonic resections have performed laparoscopically for cancer. Prospective studies must include opportunities for both the discovery of trocar site recurrence and documenting this entity carefully.

Randomized comparison of conventional carbon dioxide insufflation and abdominal wall lifting for laparoscopic cholecystectomy.

BACKGROUND: Gasless laparoscopy using abdominal wall lifting (AWL) has been developed in an attempt to avoid the adverse effects of carbon dioxide pneumoperitoneum that may occur in conventional laparoscopy. However, lifting has been criticized for its poor operative space and surgical invasiveness. This study compared the AWL method with conventional CO2 pneumoperitoneum for laparoscopic cholecystectomy with respect to operation performance, postoperative course, and stress response. PATIENTS AND METHODS: During a 6-month period, 95 patients with symptomatic gallstones were randomly assigned to receive laparoscopic cholecystectomy with conventional CO2 pneumoperitoneum (CO2 group; N = 47) or the AWL method (AWL group; N = 48). Operative results and operative time were recorded. Cardiopulmonary functions were assessed, and arterial blood gases were analyzed during surgery. Urinary cortisol, vanillylmandelic acid, metanephrines, and nitrogen loss; serum complement 3, C-reactive protein, and interleukin-6; postoperative pain; and the presence of nausea and vomiting were assessed for 48 hours after surgery. Postoperative time to recovery of flatus, tolerance of a full oral diet, and full activity were also determined. RESULTS: Only three significant differences were found. First, intraoperative ventilatory function deteriorated significantly less in the AWL group. Second, arterial blood gas determinations and capnography showed a greater decrease in intraoperative arterial pH and compliance with CO2 retention and an increase in peak airway pressure in the CO2 group (P < 0.05), reflecting poorer ventilatory performance. Third, preparation time and total operating time were significantly greater with the AWL method (P < 0.05). CONCLUSIONS: Although AWL required a longer operation time, our results suggest that the technique may still have value in high-risk patients with cardiorespiratory diseases.

Outcome of prenatally diagnosed anterior abdominal wall defects.

One hundred consecutive cases of confirmed anterior abdominal wall defect, identified prenatally in the Oxford Prenatal Diagnosis Unit over 11 years, were studied. Fifty nine per cent of cases were suspected omphaloceles and 41% suspected gastroschisis. Fifty four per cent of omphaloceles were accompanied by other defects compared with 5% of those with gastroschisis. Overall, 29% of fetuses with omphalocele had an abnormal karyotype, and of those with another abnormality identified on scan (excluding four cases with no karyotype performed), 54% had an abnormal karyotype. Of the 27 cases with suspected isolated omphalocele, 14 were live born, all of whom have survived. If the 11 whose parents opted for termination of pregnancy are excluded, survival to birth was 88%. Six of the suspected isolated omphaloceles have Beckwith Wiedemann syndrome (BWS). Eight (57%) of the live born babies with omphaloceles had major problems up to the age of 2, but only one (7%) has long term major problems. This child has BWS and is deaf. Of the 39 cases of suspected isolated gastroschisis, 33 (85%) pregnancies resulted in live birth and one in neonatal death after surgery. Survival rate (excluding terminated pregnancies) was 97%. Gastroschisis was associated with a younger maternal age than omphalocele (p < 0.001) and lower birthweight centile (p < 0.01). Fifteen per cent of the gastroschisis babies had major problems up to the age of 2 years and 12% long term developmental problems. Ninety three per cent of the omphalocele babies and 88% of those who had gastroschisis have no long term problems. Over the study period there have been major changes in scanning equipment and expertise. Since 1991 no woman with a suspected isolated lesion has opted for termination of pregnancy.

Fetal anterior abdominal wall herniations: ultrasonographic diagnosis.

Gastroschisis and omphalocele are congenital abdominal wall herniations. Both are characterized by evisceratin of bowel loops, and additionally, especially in omphalocele, liver and occasionally other organs. The bowel loops present ultrasonographically as cystic masses in relation to the fetal abdomen. Sometimes the walls are thickened due to the inflammation from exposure to amniotic fluid. Ultrasonographic identification of herniated liver (omphalocele) indicates potential complex abnormalities of other organ systems, as opposed to gastroschisis, which is usually an isolated abnormality. The two entities are frequently difficult to distinguish ultrasonographically, and in fact, the surgical treatment is the same for both entities. Early diagnosis will facilitate team planning, and probable Cesarean section to avoid damage to exposed bowel loops. A case of gastroschisis and 2 cases omphalocele are presented.

Changes in abdominal wall after mesh implantation in rats.

On an incisional hernia model, we evaluated tissue reactions to three types of non-absorbable foreign materials, Prolene, Gore-Tex and flax, used for covering defects of the abdominal wall muscles in Wistar strain rats. The examinations were carried out in five 14-days intervals between the 35th and 91st days after the intervention. Our results with Gore-Tex showed the lowest tissue response, the lowest inflammatory cellular as well as fibroplastic reaction, it also completely covers the artificially made wall defect and induces no considerable peritoneal adhesion. In defects filled with Prolene mesh, we also observed no considerable cellular response and scarring. However, considerable peritoneal adhesions were found and the defect was filled to a great extent with lipidic tissue with irregularly distributed Prolene fibres. The use of flax material is least suitable since it induces extensive inflammatory reactions, which occur even after a very long time after the operation. Prolene was, as a matter of fact, second to Gore-Tex in the experimental evaluation of the biological tolerance. However, with respect to its ten times lower price, it can be recommended as a material of the first choice for covering defects of the abdominal wall in clinical use.
