A 66-year-old man, who was a passenger in a car involved in a low-speed head-on motor vehicle accident, was rushed to our hospital. His abdomen was tender and distended. An enhanced computed tomography scan showed a massive retroperitoneal hematoma, and its three-dimensional imaging revealed an active leak of the contrast medium from the aortic bifurcation. He went into shock, and was immediately transferred to the operating theater. Through a median laparotomy, a ruptured site measuring 5 mm in diameter was found at the aortic bifurcation and it was closed with sutures under a proximal aortic control. The other organs showed no evidence of injury. Because of the remarkable edema of the bowel, mesentery, and retroperitoneum, the abdomen was temporarily closed with a mesh sheet to prevent the occurrence of abdominal compartment syndrome. A delayed closure was then successfully performed 4 days later, and he was discharged with no residual sequelae 17 days after the initial operation.
PURPOSE: Morgagni hernias are uncommon diaphragmatic hernias that are generally asymptomatic, and so far only limited data have been reported. The objective of this retrospective study was to evaluate the outcome of patients presenting with a complicated Morgagni hernia and who undergo a transabdominal repair. METHODS: Between September 1999 and October 2005, 11 patients with Morgagni hernia were operated on in our department. Eight of them had acute presentations because of a complicated Morgagni hernia. The patient demographics, presenting symptoms, operative approach, and complications were collected. The postoperative course was evaluated for morbidity and mortality. RESULTS: The patients' ages ranged from 42 to 85 years (mean 69.4). Two (18.2%) patients were male and nine (81.8%) patients were female. Chest roentgenograms, computed tomography, and contrast meal studies were used as diagnostic utilities. A transabdominal approach was used for all patients. One patient died due to pulmonary failure. The mean follow-up was 2.8 years. There was no recurrence or symptoms regarding the operation in the remaining patients. CONCLUSION: We recommend the transabdominal approach in patients with Morgagni hernia as it makes it easy to reduce the hernia contents and repair of the hernia sac. Moreover, when complicated with strangulation, incarceration or perforation, a surgical repair through a transabdominal approach is mandatory.
OBJECTIVE: The abdominal compartment syndrome is a potentially life-threatening condition with frequent renal involvement. There are few if any means of inferring subclinical effects before organ dysfunction. Because intrarenal pressure correlates with renal sonographic indices in other renal diseases, the purpose of this study was to determine the relationship between increasing intraabdominal hypertension and renal vascular flow velocities in a porcine model using renal Doppler ultrasound. DESIGN: Animal study. SETTING: University research laboratory. SUBJECTS: Eight anesthetized, mechanically ventilated, well-hydrated, 30-kg female Yorkshire pigs. INTERVENTIONS: Intraabdominal hypertension was induced by instillation of warmed intraperitoneal saline through a midline laparoscopic port. Intraabdominal pressure (IAP) was continuously monitored directly from the peritoneum and indirectly from the bladder. IAP was varied from 0 to 50 mm Hg in increments of 5 mm Hg. At each IAP level, gray-scale, color, and spectral Doppler renal arcuate artery ultrasound was obtained and resistive index (RI) and peak airway pressure calculated. MEASUREMENTS AND MAIN RESULTS: Excellent agreement between direct and indirect IAP was found (bias, 0.032 mm Hg; 95% limits, -5.5 to 5.6 mm Hg). A linear relationship between RI and indirect IAP was observed and was defined by the regression equation: RI = 0.553 + 0.0104 x bladder pressure. There was a trend toward different RIs between left and right kidneys (p = .052) at the same IAP. RI varied in a linear fashion at low peak airway pressure and demonstrated an inflection point with steeper subsequent slope after peak airway pressure of 30 cm H2O. RI values rapidly returned to near baseline after abdominal decompression. CONCLUSIONS: In this model, the renal artery RI correlated strongly and linearly with the severity of intraabdominal hypertension, making renal Doppler ultrasound a potential noninvasive screening tool for the renal effects of intraabdominal hypertension. Further studies are warranted.
