Congenital soft tissue necrosis of the right anterior abdominal wall.

A rare case of congenital soft tissue necrosis of the right anterior abdominal wall in a newborn baby is described. The defect, which measured 10 X 8 cm at birth, appeared spontaneously and healed completely within 8 weeks with conservative management. Only one other similar case is known to have been reported in the literature hitherto, but in that patient the "ulcer" was presumed to have been caused by faulty technique in fetoamniography: the fetus was traumatized by the needle used to inject the contrast material. In the present case, the etiology was unknown.

Warm receptors in the dorsal abdominal wall of the rabbit.

Warm stimulation of a circumscribed region of the dorsal abdominal wall of the rabbit evoked discharges in splanchnic afferent single fibers. They showed positive temperature coefficients of their static activities and of their dynamic responses to temperature changes. They were not excited by mechanical stimuli. Cooling from static conditions caused a transient inhibition of impulse frequency. Two populations were found, one having a static and dynamic maximum at 46 degrees C, the other one at about 40 degrees C. Both types were found to be C-fibers, with a conduction velocity of 0.6 - 1.1 m/sec.

The encircling mesh in abdominal wall surgery: rationale and technical details of a dorso-ventral physiological restoration.

We describe a new, functional surgical technique, known as 'encircling mesh', designed to address abdominal wall problems. The rationale of the procedure is to connect the anterior and posterior trunk muscle compartments by means of a purpose built polypropylene mesh that encloses a belt shifted posteriorly across the spine subcutaneously, through use of a disposable introducer. The technical details and a case presentation, with specific references to the cosmetic and functional outcomes are described.

Synovial sarcoma of the abdominal wall. Light microscopic, histochemical and electron microscopic investigations.

A synovial sarcoma of the abdominal wall in a 56-year old woman showed the typical features of this tumor type. Histologically a characteristic biphasic cellular pattern with epithelium-like cell complexes and sarcomatous spindle cell areas was found. The histochemical examination revealed that tumor cells synthesize glycoproteins and weakly acid glycosaminoglycans (mainly hyaluronic acid). Electron microscopically the tumor cells in epithelium-like cell islets were sometimes arranged in gland-like formations with microvilli at the luminal side, specialized intercellular junctions and a peripheral basement membrane-like condensation of the ground substance. There was no fundamental cytological difference between cells of epithelium-like and spindle cell areas. Generally the tumor cells imitated cells of the synovial membrane and we found no evidence for origin from cells of the nerve sheath. Because of the submicroscopic relationship and histochemical similarities of synovial sarcomas and mesotheliomas we suggest that they should be united in a group of sarcomas with possible biphasic cellular pattern, while preserving their clinicopathologic definition.

Femoral hernia with upward extension into abdominal wall: CT diagnosis.

The usefulness of computed tomography (CT) in identifying the nature of abdominal masses is well documented. A rare form of femoral hernia was observed extending upward within the abdominal wall. CT was helpful in determining that this was a hernia and not an intraabdominal mass.

The relative merits of various methods of indirect measurement of intraabdominal pressure as a guide to closure of abdominal wall defects.

Visceral ischemia secondary to increased intraabdominal pressure (IAP) following closure of abdominal wall defects presents a serious postoperative problem. Currently, the method of closure and postoperative management are determined by clinical impressions rather than measurement of IAP. In this study various methods of indirectly measuring IAP were compared in 17 rabbits in which IAP was sequentially increased with an intraabdominal balloon. Vesical and inferior vena caval (IVC) pressures were found to have good statistical correlation with IAP. Other methods tested were gastric, rectal, superior vena caval, femoral and brachial artery, and rectus compartment pressures. All were found to be poor indicators of actual IAP. In nine of the rabbits, radiolabeled microspheres were used to assess cardiac output and visceral blood flow. Renal blood flow was very sensitive to increased IAP with dramatic impairment at IAP above 10 to 15 mmHg. Small intestinal flow was less sensitive and did not become significantly diminished until IAP exceeded 25 to 30 mmHg. Our studies suggest that vesical and IVC pressure monitoring should be used to evaluate IAP in the clinical setting. If IAP is in excess of 10 to 15 mmHg surgical intervention is indicated to prevent the development of renal ischemia.

Gastroesophageal reflux in children with a congenital abdominal wall defect.

BACKGROUND/PURPOSE: Gastroesophageal reflux (GER) is considered common in patients with congenital abdominal wall defects (CAWD). The aim of this study was to find out the frequency of GER in children with CAWD and, in particular, whether there is difference between patients with omphalocele and gastroschisis. METHODS: Forty-two children, 19 with gastroschisis and 23 with omphalocele were examined for GER at the median age of 12.0 months (range, 1 to 132). Esophagoduodenoscopy with biopsies was performed on all patients. Eighteen patients underwent 18-hour esophageal pH-monitoring. RESULTS: GER was detected in 13 patients. All but one patient of the 13 had either macroscopic or microscopic esophagitis. One patient had pathological pH monitoring only. In children with omphalocele, the incidence of GER was 43% (10 of 23), whereas in gastroschisis patients the incidence was 16% (3 of 19), (P value, not significant). The median age of omphalocele patients with GER was significantly lower (7 months) than the median age of those without GER (72 months; P = .01). In patients with gastroschisis age made no difference. Six of 32 patients (19%) with primary fascial closure (small defects) had GER, whereas 7 of 10 patients (70%) in which primary fascial closure was impossible (large defects) had GER (P < .01). CONCLUSION: CAWD patients, especially those with omphalocele and a large defect have a high incidence of GER complicated by esophagitis during the first few years of life.

[Early embryonal maldevelopment of the umbilical cord with defect of the abdominal wall and severe body malformations (dysplasia umbilico-fetalis) (author's transl)].

A case of dysplasia umbilico-fetalis is demonstrated. The malformation comprises a rare and strange reduction anomaly of the feto-umbilical unit, which is caused during early embryonic life (around the 7 mm stage, corresponding to the end of the third week of gestation). The cause of the damage is not known. The folding off of the embryo from the yolk sac and the development of the abdominal stalk are impaired. No abdominal wall is formed, and the umbilicus and umbilical cord are not developed. The abdominal organs are enclosed in a short amnion-mesoderm tube, which is bordered by the retroperitoneum at the fetal side and by the chorionic plate at the placenta side. The umbilical vessels are only a few centimeters long and traverse in the mesodermal layer of the amnion-mesoderm tube. The thin wall of the tube usually ruptures before birth, thus causing an abacterial fibrinoid peritonitis by the chemical irritation of the peritoneum through the constituents of the amniotic fluid. The lower extremities of the fetus reveal varying degrees of reduction deformities. One leg and large parts of the pelvis may be entirely missing, if the side of origin of the extremity is included in the amnion-mesoderm tube. Severe kyphoscoliosis is probably a secondary phenomenon. In addition, malformations of the inner organs occur such as caudal displacement and hernia of the diaphragma, hypoplasia of the lungs, dysplasia of the genito-urinary tract and non-rotation of the gut. The pathophysiology of the rare developmental defect and its secondary implications are discussed with special reference to related malformations such as omphalocele and infraumbilical defect of the abdominal wall.

Massive incisional hernia: abdominal wall replacement with Marlex mesh.

Marlex (polypropylene) mesh was used to replace the abdominal wall in massive incisional herniation in 50 patients. Seventeen unsuccessful attempts at primary repair had previously been made on nine patients. Patient follow-up ranged from 6 to 120 months (mean = 45 months). There was minor hernia recurrence in four (8 per cent) patients. In each instance it was due to partial detachment of the peripheral fixation of the patch. Complications were: wound infection, four (8 per cent); wound seroma, two (4 per cent); wound haematoma, one (2 per cent); and wound sinus, six (12 per cent). Complications did not necessitate removal of the patch in any case. Inadequate peripheral attachment of the patch has been the only cause of hernia recurrence and should be avoidable.

Accurate diagnosis of detrusor areflexia using combined uroflowmetry and abdominal wall electromyography.

Twenty-three patients who previously demonstrated no detrusor contraction during cystometry were evaluated using a combined uroflowmetry and abdominal wall electromyography. Ten patients voided without abdominal straining (normal detrusor reflexia), 11 could not void without abdominal straining (detrusor areflexia, detrusor weakness, or bladder outlet obstruction), and 2 had equivocal findings with the method.
