Prediction of successful primary closure of congenital abdominal wall defects using intraoperative measurements.

To determine whether intragastric pressure (IGP) and central venous pressure (CVP) would reliably predict successful primary closure of congenital abdominal wall defects (omphalocele/gastroschisis) in newborn infants, we developed the following prospective intraoperative management protocol. Following a temporary trial of fascial closure, infants who had an IGP less than 20 mm Hg or an increase in CVP of less than 4 mm Hg were primarily closed. If IGP was greater than 20 mm Hg or if CVP increased by more than 4 mm Hg, the temporary closure of the abdomen was reopened and a prosthetic silo was placed. Ten infants who were less than 24 hours old and averaged 2.7 kg (range, 1.4 to 4.2 kg) and 37-weeks gestation (range, 32 to 41 weeks) were studied. Eight infants met criteria for primary closure. Their IGP averaged 14 +/- 4 mm Hg (+/- SD) (range, 8 to 19 mm Hg), and their increase in CVP averaged 1 +/- 2 mm Hg (range, -2 to 3 mm Hg). In the two infants who required staged repair, IGP averaged 25 +/- 1 mm Hg (+/- SD) (range, 24 to 25 mm Hg), and the increase in CVP averaged 7 +/- 1 mm Hg (range, 6 to 8 mm Hg). All patients were anesthetized with fentanyl (12.5 micrograms/kg) and paralyzed with metocurine (0.3 mg/kg) intraoperatively. There were no postoperative complications in either group of patients related to increased intraabdominal pressure, and all patients were extubated within 48 hours of the initial surgery. We conclude that the intraoperative measurement of changes in IGP and CVP can serve as a guide to the operative management of congenital abdominal wall defects and can reliably predict successful outcome following repair.

Abdominal wall competence after free transverse rectus abdominis musculocutaneous flap harvest: a prospective study.

A prospective study was designed to evaluate the possible changes in abdominal wall strength following free transverse rectus abdominis musculocutaneous (TRAM) flap surgery for breast reconstruction. Twenty-two patients were examined 1 day before surgery, and at 3, 6, and 12 months postoperatively. Trunk muscle strength was measured by the same physiotherapist using an isokinetic dynamometer (Lido Multi Joint II, Loredan Biomedical Inc., Davies, CA). The peak torque and average torque for both flexion and extension at 60 degrees per second angular velocity were recorded from the curves obtained. There was a significant reduction in trunk flexion strength at 3 months postoperatively (peak torque mean, 92% of the preoperative value; p = 0.04), but this was corrected by 6 months (mean, 96%), and improved to 98% by 12 months. The patient's ability to do curled trunk sit-ups was evaluated by the same physiotherapist and graded on a scale from 1 to 6. In 9 of 19 patients the operation had no effect on sit-up performance during follow-up. In 10 of 19 patients there was a reduction of one or two grades at 3 months that did not improve by 12 months. Magnetic resonance imaging of the abdominal wall was performed on 9 patients. The mean area of the upper third of both rectus muscles was measured on the axial images. At 3 months postoperatively the mean area of the upper third of the donor muscle was significantly larger than the contralateral (p = 0.03). There was no difference in size at 6 months, and by 12 months the donor side was smaller. This prospective study shows that harvesting of a free TRAM flap can cause a subclinical reduction in abdominal strength, although this was not noticed by the patients themselves.

Abdominal wall hernias: cross-sectional imaging signs of incarceration determined with sonography.

OBJECTIVE: The aim of this study was to determine with sonography whether distinct cross-sectional imaging signs exist that may differentiate between incarcerated and nonincarcerated abdominal wall hernias. SUBJECTS AND METHODS: The sonographic appearance of 149 consecutive abdominal wall hernias was prospectively investigated and correlated with subsequent surgical results. Commercially available 4- to 10-MHz linear transducers and 2- to 5-MHz curved transducers were used to evaluate the hernias. RESULTS: Surgery revealed 126 nonincarcerated and 23 incarcerated hernias. The sonographic signs suggestive of incarceration that we identified included free fluid in the hernia sac, which was observed in 91% of the incarcerated hernias and in 3% of the nonincarcerated hernias; bowel wall thickening in the hernia, which was detected in 88% of the incarcerated hernias and in none of the nonincarcerated hernias; fluid in the herniated bowel loop, which was detected in 82% of the incarcerated hernias and in 3% of the nonincarcerated hernias; and dilated bowel loops in the abdomen, which occurred in 65% of the incarcerated hernias and in none of the nonincarcerated hernias. These imaging findings allowed the identification of incarceration in all 23 cases and led to a false-positive result in two of 126 nonincarcerated hernias. CONCLUSION: Cross-sectional imaging signs indicating hernial incarceration included free fluid in the hernial sac, bowel wall thickening in the hernia, fluid in the herniated bowel loop, and dilated bowel loops in the abdomen. Sonography is an appropriate cross-sectional imaging modality for detecting these signs that are helpful in diagnosing patients with atypical clinical presentations.

Abdominal wall hernias as a complication of peritoneal dialysis.

Home peritoneal dialysis has recently become an important addition to the therapy of chronic renal failure. Abdominal wall hernias have become more apparent as complications of this mode of dialysis, with isolated instances of incarcerations and one fatality. Results of our review of 276 patients receiving peritoneal dialysis revealed seven with hernias, an incidence of 2.5 per cent. Six patients with hernias were receiving c.a.p.d.; one patient was receiving c.c.p.d., and none was receiving i.p.d., for incidences of 17, 5 and zero per cent, respectively. All hernias found at presentation occurred within two to 20 months after peritoneal catheter placement. Most were ventral or umbilical, and all were repaired electively without serious complications. All patients with hernias had associated problems with leaks, peritonitis or predialysis hernias. In two of four patients with predialysis hernias, herniorrhaphy without catheter removal resulted in two recurrences. Abdominal wall hernias are a more frequent complication of c.a.p.d. and c.c.p.d., modalities which require large volumes of peritoneal dialysate during ambulatory hours. Review of the literature reveals that wound tensile strength and healing are decreased in those patients having renal disease with uremia, anemia and malnutrition. However, these factors do not increase the over-all incidence of hernias. Patients should be screened for hernias, and hernias should be repaired prior to catheter placement. Hernias presenting during dialysis are best treated by herniorrhaphy and hemodialysis postoperatively or low volume peritoneal dialysis to optimize the metabolic state.

Subcutaneous emphysema of the abdominal wall from diverticulitis with necrotizing fasciitis.

The case history of a patient with subcutaneous emphysema of the abdomen from sigmoid diverticulitis is presented. The mechanisms for developing abdominal wall emphysema are reviewed. Thus when the gas originates from the gastrointestinal tract, mechanical factors are mainly responsible for this phenomenon. These inculde a direct communication through a colonocutaneous fistula. Gas may, however, also be spread into the abdominal wall by high intraintestinal pressures. Infection with gas-producing organisms may be associated with subcutaneous emphysema. This is particularly true when the emphysema develops 48 h or longer after onset of symptoms. Infection, however, is not the major cause for gas in these tissues.

Abdominal wall implantation of an endocervical-like mucinous borderline tumor.

We present the case of a 21-year-old woman in whom development of a bulky abdominal wall metastasis in a laparotomy scar led to discovery of bilateral endocervical-like mucinous borderline tumors in normal-sized ovaries. Tumor implants were also present in the mesosalpinx and a pelvic lymph node. We hypothesize that the abdominal wall metastasis resulted from seeding at the time of a prior exploratory laparotomy for trauma, before the ovarian tumors were discovered. We present evidence to support our theory of mechanical implantation of borderline tumor and explore other mechanisms leading to extraovarian mucinous neoplastic involvement.

A radical approach to bacterial panniculitis of the abdominal wall in the morbidly obese.

The morbidly obese patient, although at risk for many perioperative complications of radical surgery, paradoxically presents the opportunity for wide excision of abdominal soft-tissue infections. This report describes the successful radical surgical management of bacterial panniculitis of the abdominal wall occasioned by a variety of extrafascial and intraperitoneal sources in 13 patients. All patients were followed up for a minimum of 2 years, except for one patient who died 2 months after hospital discharge. The remainder are alive with intact fascial closure and no pannicular infection. A radical approach to the infected abdominal wall, incorporating wide en-bloc excision of skin, subcutaneous tissue, muscle, and strangulated intestine, facilitates successful fascial and skin closure in a noninfected field in the morbidly obese.

Laparoscopic exposure in obese high-risk patients with mechanical displacement of the abdominal wall.

BACKGROUND: Patients with morbid obesity or pulmonary disease are at a higher risk for complications during advanced laparoscopic procedures. Higher intraperitoneal carbon dioxide pressures required to elevate the pannus can negatively impact hemodynamic and respiratory parameters. CASES: We describe a technique that uses a combination of a mechanical retractor and a Foley catheter inserted midway between the umbilicus and the pubic symphysis that assists in elevating the anterior abdominal wall. In 3 cases this technique allowed for a low-pressure pneumoperitoneum during advanced laparoscopic pelvic surgery, which resulted in improved hemodynamic parameters and pulmonary function in these high-risk patients. CONCLUSION: The Foley Lap-Lift facilitated laparoscopy through mechanical abdominal wall elevation and allowed for a lower-pressure pneumoperitoneum. This technique is an addition to traditional operative laparoscopy in select high-risk patients.

Impact of demographic factors on prenatal diagnosis and elective pregnancy termination because of abdominal wall defects, Hawaii, 1986-1997.

OBJECTIVE: The intent of this study was to investigate the impact of various demographic factors on the antenatal diagnosis and elective termination of abdominal wall defect pregnancies. METHOD: Data were obtained from a birth defects registry in Hawaii between 1986 and 1997. RESULTS: The antenatal diagnosis rate was higher for gastroschisis than for omphalocele (76 vs. 60%). However, gastroschisis pregnancies were substantially less frequently electively terminated than omphalocele pregnancies (8 vs. 29%). Factors such as year of diagnosis and delivery, maternal age, race/ethnicity, residence, and maternal serum alpha-fetoprotein screening affected the prenatal diagnosis and/or elective termination of both omphalocele and gastroschisis pregnancies, but frequently in different ways. CONCLUSION: This investigation determined that antenatal diagnosis and elective termination varied with the type of abdominal wall defect and selected demographic factors.

[Prenatal diagnosis of neural tube and abdominal wall defects in the 2d trimester].

Combined alpha-fetoprotein screening in serum and specified sonographic examination has proved useful in prenatal diagnosis of neural tube and abdominal wall malformations. 207 amniocenteses were performed within a period of 3 years due to pathologic serum alpha-fetoprotein values and/or abnormal sonographic findings. 101 amniotic fluid specimens showed an increase of alpha-fetoprotein of more than 2.5 times the average value. 60 malformed neural tubes, 17 foetuses with abdominal wall defects, as well as 2 other malformations, were diagnosed. "Open" defects, as well as 17 false positive AFP values, were discovered through the electrophoretic presence of ZNS-specific acetylcholinesterase in the amniotic fluid.

Diffuse abdominal wall cellulitis in ascending omphalitis--a lethal association in neonatal necrotizing fasciitis.

Necrotizing fasciitis is a grave complication of ascending omphalitis in the neonate, but because it is rare some of the signs are not well documented. Rapidly progressive anterior abdominal wall edema and cellulitis were noted in 16 patients who were clinically diagnosed with necrotizing fasciitis. Fifteen of these patients died soon after emergence of anterior abdominal wall edema and cellulitis. The appearance of anterior abdominal edema and cellulitis in a patient with ascending omphalitis has serious implications and demands intensive care if the patient is to survive.

Degree of fetal umbilical venous constriction at the abdominal wall in a low-risk population at 20-40 weeks of gestation.

OBJECTIVES: To determine the degree of constriction of the umbilical vein at the abdominal wall in the second half of pregnancy. METHODS: A total of 283 low-risk singleton pregnancies were recruited for a cross-sectional study, and examined once at 20-40 weeks of gestation. Two sets of ultrasound measurements of the umbilical vein were taken: one at the fetal end of the umbilical cord and another at the inlet through the abdominal wall, the umbilical ring. The diameter was determined as an average of >or=5 repeat measurements. The blood velocity was recorded at the same site. RESULTS: The time-averaged maximum venous blood velocity in the cord was low (mean 13-19 cm/s during 20-40 weeks of gestation), and the corresponding mean diameter 3.6-8.2 mm. In contrast, the mean of the venous blood velocity at the umbilical ring was 34-41 cm/s and the diameter was 2.8-5.9 mm during the same period. Of 191 pairs of observations, 41 (21%) had a velocity increment of >or=300 %, which corresponds to a diameter reduction to half or more at the umbilical ring. CONCLUSION: Constriction of the umbilical ring is a common phenomenon in the second half of pregnancy.
