Markedly elevated levels of vascular endothelial growth factor, fibroblast growth factor, and interleukin 6 in Meigs syndrome.

Analysis of serum and peritoneal and pleural fluid from a patient with Meigs' syndrome revealed high levels of vascular endothelial growth factor, fibroblast growth factor, and interleukin 6. Serum levels declined after removal of the ovarian tumor, along with resolution of ascites and hydrothorax. These findings suggest the involvement of these vasoactive factors in ascites and pleural fluid formation in Meigs' syndrome.

Surgical shunts and TIPS for variceal decompression in the 1990s.

BACKGROUND: In the 1990s, liver transplantations and transjugular intrahepatic portosystemic shunts (TIPS) have become the most common methods to decompress portal hypertension. This center has continued to use surgical shunts for variceal bleeding in good-risk patients who continue to bleed through endoscopic and pharmacologic treatment. This article reports this center's experience with surgical shunts and TIPS shunts from 1992 through 1999. METHODS: Sixty-three patients (Child A, 43 patients; Child B, 20 patients) received surgical shunts: distal splenorenal, 54 patients; splenocaval, 4 patients; coronary caval, 1 patient; and mesocaval, 4 patients. Sixty-two patients had refractory variceal bleeding, and 1 patient had ascites with Budd-Chiari syndrome. Two hundred patients (Child A, 24 patients; Child B, 62 patients; Child C, 114 patients) received TIPS shunts. One hundred forty-nine patients had refractory variceal bleeding, and 51 patients had ascites, hydrothorax, or hepatorenal syndrome. Data were collected by prospective databases, protocol follow-up, and phone contact. RESULTS: The 30-day mortality rate was 0% for surgical shunts and 26% for TIPS shunts; the overall survival rate was 86% (median follow-up, 36 months) for surgical shunts and 53% (median follow-up, 40 months) for TIPS shunts. For surgical shunts, the portal hypertensive rebleeding rate was 6.3%; the overall rebleeding rate was 14.3%. For TIPS shunts, the overall rebleeding rate was 25.5% (30-day, 9.4%; late, 22.4%). There were 4 reinterventions for surgical shunts (6.3%); the reintervention rate for TIPS shunts in the bleeding group was 33%, and the reintervention rate in the ascites group was 9.5%. Encephalopathy was severe in 3.1% of the shunt group and mild in 17.5%; this was not systematically evaluated in the TIPS shunts patients. CONCLUSIONS: Surgical shunts still have a role for patients whose condition was classified as Child A and B with refractory bleeding, who achieve excellent outcomes with low morbidity and mortality rates. TIPS shunts have been used in high-risk patients with significant early and late mortality rates and have been useful in the control of refractory bleeding and as a bridge to transplantation. The comparative role of TIPS shunts versus surgical shunt in patients whose condition was classified as Child A and B is under study in a randomized controlled trial.

Percutaneous nephrolithotomy: spinal cord injury vs. ambulatory patients.

One hundred patients, 35 with spinal cord injury (SCI) and 65 who were ambulatory, underwent percutaneous nephrolithotomy (PNL). Success of complete stone excision, operative morbidity and mortality were compared in the two patient populations. Stone size and complexity were evaluated by X-ray and a single-stage PNL was done using general anesthesia, bi-planar C-arm fluoroscopy, Amplatz renofascial dilators, and two guide wires. Eleven percent of the patients had previously-placed percutaneous nephrostomy tubes for hydronephrosis and/or pyonephrosis. In the ambulatory group, 98.5% (64/65) were stone-free after the procedure as compared to 85.7% (31/35) in the SCI group. The success rate in those patients who followed postoperative instructions exceeded 96% in both groups of patients. One operative mortality, related to infectious complications, occurred in the SCI group. Major morbidity in the SCI population consisted of three perirenal abscesses, a hydrothorax, an aspiration pneumonia, a respiratory arrest and a nephro-colonic fistula for a rate of 20% (7/35), or 7% of all patients. One major complication, a nephroduodenal fistula, occurred in the ambulatory population. Four patients, three of whom were SCI, required open surgery related to infectious complications. Other significant complications consisted of hemorrhage requiring transfusion, and fever (101.5 degrees F). Minor complications included dislodged nephrostomy tubes, retained stones, and ureteral edema causing obstruction. These complications were three times more common in the SCI population. Percutaneous nephrolithotomy is an effective surgical means for stone removal for SCI and ambulatory patients. The SCI patient has a high incidence of infectious complications causing increased morbidity and mortality.

Chemohyperthermia for advanced abdominal malignancies: a new procedure with closed abdomen and previously performed anastomosis.

ChemoHyperthermic Peritoneal Perfusion (CHPP) after cytoreductive surgery is a relatively new procedure in the treatment of abdominal carcinomatosis or sarcomatosis. An assessment of the CHPP technique performed on 20 patients suffering from abdominal malignancies was carried out. After surgical debulking and gastrointestinal anastomosis, two Tenckhoff catheters were positioned for the immediate performance of CHPP, which was carried out at 42-43 degrees C for 1 h, after closing the abdomen. In 19 assessable patients, 47.3% and 36.8% complete responses (CR) were recorded at 1 and 6 months, respectively, with responses of 37.5% in patients affected with gastrointestinal cancer and 50% in patients affected with ovarian cancer. CR were obtained only in patients who had undergone accurate peritoneal debulking. Survival rate for gastrointestinal and ovarian cancer was 68% at 12 months. Patients who underwent radical cytoreductive surgery are all alive at a follow-up median time of 17 months. Two anastomotic leakages with spontaneous recovery were observed, along with one hydrothorax, which was immediately drained during the procedure, three cases of chemotherapic gastrointestinal toxicity, one sepsis, one renal failure that required a transient dialysis, and one cholecystitis that required cholecystectomy. One patient died 30 days after CHPP of a cardiac ischaemia not strictly related to the surgical procedure. In the authors' experience, CHPP with closed abdomen after reconstructive gastrointestinal surgery is a safe and feasible treatment with acceptable side effects.

Complications associated with percutaneous nephrostomies. A retrospective study.

PURPOSE: To determine the morbidity and mortality associated with radiologically guided percutaneous nephrostomy (PCN). MATERIAL AND METHODS: A retrospective analysis of 401 patients treated with 569 PCN over a 5-year period was performed. Using the Seldinger technique, the catheters (6-10 F) were placed under fluoroscopic, ultrasonographic, or CT guidance. Data on underlying disease, complications, subsequent management, and long-term management were collected. RESULTS: PCN was successful in 558 of the 569 attempts (98%). There were 22 major complications (4%) in 569 procedures, including cardiac arrest, bleeding requiring transfusion or embolization, septicemia, hydrothorax or pneumothorax. There were 38% minor complications, including urinary tract infection, catheter dislodgement, catheter obstruction by debris, urinary leakage, and inflammation of the skin at the site of insertion of the percutaneous catheter. Seventy-seven (14%) of the procedures were followed by urinary tract infection during the PCN treatment. Seventy-nine (14%) catheters slipped out unintentionally. CONCLUSION: Percutaneous nephrostomy is a gentle procedure associated with high technical success and low morbidity. However, the risk of the procedure has to be weighed against the expected benefit.

Hydrops foetalis caused by hepatic haemangioma.

The authors report a moderately premature baby with Down's syndrome and hydrops, the latter probably caused by a large hepatic haemangioma which was diagnosed only after birth. At birth the baby was affected by massive right hydrothorax, ascites, hypoalbuminaemia and severe respiratory distress. With the use of modern neonatal intensive care, the baby survived. Corticosteroid treatment (prednisolone 2 mg kg(-1) d(-1) i.v. in divided doses) was associated with a very rapid resolution of the haemangioma and the baby was healthy at follow-up. Although hepatic angiomas are not uncommon in the neonatal period, the association with hydrops is a rare finding.

Etiology and outcome of hydrops fetalis.

OBJECTIVES: To identify the etiology and pregnancy outcome of hydrops fetalis in a cohort of pregnancies referred to a tertiary maternal fetal medicine center in the UK. These data allow the review of a large series of pregnancies affected by hydrops fetalis and emphasize the importance of investigation and then treatment of individual cases. This provides parents with improved information and especially specific prognostic information. METHODS: A retrospective review of 63 consecutive cases of hydrops fetalis managed between September 1996 and March 1999. RESULTS: Of the pregnancies, 12.7% (n = 8) were associated with an 'immune' etiology. Of these, 62.5% (n = 5) had fetal anemia due to anti-D, 25% (n = 2) anti-Kell and 12.5% (n = 1) anti-c antibodies. The remaining 55 cases (87.3%) had a non-immune cause. Eight (14.5%) were due to human parvovirus B19 infection. Fourteen cases (25.5%) were associated with aneuploidy and, in four (7.3%), a primary hydrothorax was the cause of the non-immune hydrops fetalis. A cardiac cause was found in five (9.1%) cases. Three of these had supraventricular tachycardia and one had congenital complete heart block. Cystic hygroma was associated with hydrops fetalis in six cases. Twin-twin transfusion syndrome was the cause for hydrops in two cases. Massive transplacental hemorrhage was identified in one case. Fetal akinesia and muscular dystrophy caused hydrops in one case each. In 14.5% (8/55) of cases no obvious cause was identified and these were classified as 'idiopathic'. Three other cases could not be classified because parents declined investigations (unclassified). In the pregnancies with non-immune hydrops fetalis, the outcome was favorable in 27.3% (15/55) of cases. CONCLUSION: The prognosis of hydrops fetalis differs markedly between different etiological groups. Etiologies range from treatable causes with a good outcome and probably no long-term side-effects (as in case of parvovirus B19), to others which are incompatible with life or are associated with considerable perinatal morbidity and mortality.

Single upper-pole percutaneous access for treatment of > or = 5-cm complex branched staghorn calculi: is shockwave lithotripsy necessary?

BACKGROUND AND PURPOSE: Percutaneous nephrolithotomy for staghorn calculi is reported to have a residual stone rate of 28%, while shockwave lithotripsy alone results in residual stones in approximately 50% of cases. Combination therapy, sandwich therapy, and multiple percutaneous accesses have also been advocated for staghorn stones. We believe these stones can often be removed with a staged procedure via a single upper-pole percutaneous access using flexible nephroscopy and the holmium:YAG laser. Our experience is reviewed. PATIENTS AND METHODS: The hospital records of patients having a cumulative stone burden > or =5 cm who underwent percutaneous nephrolithotripsy (PCNL) for a single complex staghorn calculus were reviewed. There were 15 male and 34 female patients having 45 complete and 7 partial staghorn calculi constituting a mean stone burden of 6.7 cm (range 5.0-10.0 cm). A calix was punctured that would provide access to the majority of the involved calices. Thirty-five renal units were approached through a single upper-pole percutaneous access, and four and six renal units were accessed through single middle or lower-pole calices, respectively. The remaining seven renal units were treated with multiple percutaneous accesses. RESULTS: In the renal units having only a single access, a mean of 1.6 (range 1-3) procedures were required to achieve stone-free status. The mean operating room time was 2.9 hours (range 2.0-3.5 hours). For the second PCNL, the mean operating room time was 63 minutes (range 30-90 minutes). Two patients (two renal units) had residual stones <1 cm in diameter. One refused additional surgery, and the other is awaiting further treatment. The mean estimated blood loss was 238 mL (range 50-800 mL), with only one procedure (2.2%) necessitating a blood transfusion. One (2.8%) hydrothorax developed among the 35 upper-pole puncture cases. Six patients had transient oral temperature readings >101 degrees F with negative blood cultures. Other early complications included single cases of leg cellulitis, atrial fibrillation, and noncardiac chest pain. There were no delayed surgical complications. Patients were discharged from the hospital a mean 2 days (range 1-10 days) after the first PCNL. CONCLUSION: Use of flexible nephroscopy with holmium:YAG laser lithotripsy and Nitinol basket stone extraction has allowed us to render staghorn-containing renal units stone free in a mean of 1.6 procedures. Of the 45 renal units treated through a single percutaneous access, 43 (95%) were rendered stone free. The holmium:YAG laser appears to be a safe lithotrite for the kidney, as no complications occurred from its use.

Safety and efficacy of supracostal access in tubeless percutaneous nephrolithotomy.

PURPOSE: To evaluate the feasibility and safety of supracostal access in tubeless percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: From September 2004 to November 2005, tubeless PCNL using supracostal access was done for 72 patients at our institute. Patients requiring more than two percutaneous tracts or with significant intraoperative bleeding or residual stone burden were excluded from the study. The outcome of these patients was compared with that of a historic cohort of similar patients having supracostal access with routine placement of a nephrostomy tube. The two groups had comparable demographic data. RESULTS: The differences in the mean drop in hemoglobin concentration, transfusion requirement, and complication rate in the two groups were not statistically significant, with three patients in the study group and four patients in the control group requiring blood transfusion. Patients undergoing tubeless PCNL required less analgesia (P = 0.000) and were discharged a mean of 19 hours earlier (P = 0.000) than those in the control group. Complete stone clearance was achieved in 90.27% of the renal units in the study group and 86.11% of the renal units in the control group. Two patients in the study group and three patients in the control group had postoperative hydrothorax, all of whom, except for one in the control group, were managed conservatively. CONCLUSION: Supracostal access in tubeless PCNL appears to be feasible, safe, and effective, offering the advantages of a lower analgesic requirement and shorter hospital stay without increasing thoracic complications. Studies with larger numbers of patients are needed to confirm these initial findings.

Upper-pole access for percutaneous nephrolithotomy: comparison of supracostal and infracostal approaches.

BACKGROUND AND PURPOSE: The advantage of upper-pole access for nephrolithotomy is direct access to most of the intrarenal collecting system and upper ureter. Upper-pole access can be achieved either supracostally and subcostally. Because of the anatomic location of the kidneys, the supracostal approach is associated with a higher rate of pulmonary complications. We compared the efficacy and safety of the supracostal and infracostal upper-pole approaches. PATIENTS AND METHODS: A total 464 patients were treated with percutaneous nephrolithotomy (PCNL) via the upper pole, of which 170 punctures (group I) were performed supracostally and 294 (group II) subcostally. In both groups, PCNL was done by the standard technique with fluoroscopic guidance. The operative time, success rate, hospital stay, and complications in the two groups were compared. RESULTS: Patients were stone free in 82.2% and 77.1% of the cases in groups I and II, respectively, and had stone fragments <4 mm in 10.7% and 14.7%, respectively. The operative time, success rate, and septic and hemorrhagic complications were not significantly different in the two groups. Hydrothorax was found in 26 patients (15.3%) of group I and 4 (1.4%) of group II. Only 9 patients (5.3%) in group I needed intercostal drainage. CONCLUSION: Percutaneous nephrolithotomy via the upper pole is effective using both supracostal and infracostal approaches, with acceptable rates of complications. The rate of pulmonary complications is higher with the supracostal approach. If the supracostal approach is indicated, it should be used with caution.

A pressure overload model of congestive heart failure in rats.

Approximately 32% of the rats used as animal models showed an elevated heart weight/body weight ratio (0.432[SEM 0.022] g.100 g-1 compared to 0.293[0.009] g.100 g-1 for sham-operated rats), a hydrothorax, pulmonary and liver congestion, and specific histological changes 82-93 weeks after surgically induced aortic constriction. The histological changes were comparable to those observed in hearts of people suffering from long term hypertension. Cardiac failure was also confirmed by depressed contractility as measured by maximum and minimum dP/dt (first derivative of left ventricular pressure), which were 4604(346) and 3627(526) mm Hg.sec-1, respectively, compared with 9165(745) and 5835(268) mm Hg.sec-1 respectively in rats that did not develop left ventricular hypertrophy and failure (CLIP rats). Systolic and left ventricular blood pressures measured under anaesthesia were also decreased: 71.6(5.0) and 88.1(6.3) mm Hg respectively in rats with congestive heart failure, compared with 83.6(2.4) and 109.5(3.6) mm Hg in CLIP rats. Except for a prolonged mean PQ interval associated with a lower heart rate and for a slightly shorter QRS interval in the conscious state, the electrocardiograms of rats with congestive heart failure did not show any major abnormalities specific to ventricular hypertrophy and/or failure. This model could be useful for studying the pathology and adaptative mechanisms in compensated pressure overload induced congestive heart failure as well as in studies comparing pathological changes and means of treatment of congestive heart failure with different aetiologies encountered in the human population.

Surgical treatment of Boerhaave's syndrome: when, how and why?

Ten cases of Boerhaave's syndrome have been treated in this hospital from 1983-1998. Nine patients underwent surgery resulting in complete recovery in seven cases and two postoperative deaths. One was treated with a satisfactory outcome. Vomiting was considered to be the determinative factor for the illness in eight cases. The relationship between the rupture of the esophagus and vomiting and the mechanism of its occurrence based on anatomy and pathophysiology is discussed. It is believed that the most beneficial time to perform surgery is based on the general condition of the patient. The surgical procedure should consist of closure of the lacerated esophagus, a complete clearance of the fibrinous coating on the surface of the pleura, mobilization of a pedicled omentum pad and a gastrostomy. The chest should be entered from the side where the esophagus was lacerated or the X-ray examination showed hydrothorax or hydropneumothorax. The most important factor to guarantee a successful outcome for surgery is a complete clear off of the empyema and early expansion of the lung in addition to effective nutritional support.

Severe ovarian hyperstimulation syndrome (OHSS) and icterus.

Severe ovarian hyperstimulation syndrome (OHSS) leads to changes in laboratory analyte concentrations. Whereas elevated aminotransferase activity is often observed, a cholestatic course with hyperbilirubinaemia and icterus seldom occurs. In this report, the case of a 33 year old patient with polycystic ovary syndrome (PCOS) is described who, after stimulation with human menopausal gonadotrophin (HMG), developed severe OHSS with haemoconcentration, ascites, hydrothorax, elevated aminotransferases, hyperbilirubinaemia and icterus. The patient did not become pregnant and the OHSS regressed, together with the normalization of laboratory and clinical parameters and disappearance of the icterus. During the course of an OHSS cholestasis with icterus may occur, which could be explained by a reactive cholestatic hepatosis as a reaction to the hormonal changes induced by the stimulation therapy.

Acute massive postoperative pleural effusion associated with asymptomatic hepatitis C-induced cirrhosis of the liver.

The development of an acute pleural effusion during the immediate postoperative period after abdominal or pelvic surgery is not uncommon. In symptomatic patients, pleural effusions often are thought to result from a complication of pulmonary embolism or parapneumonic effusion. We present a patient in whom an acute unilateral hepatic hydrothorax developed after elective total abdominal hysterectomy. Pleural effusion continued to reaccumulate for several days. After extensive efforts failed to reveal the cause of effusion, intraperitoneal radioisotope study confirmed a peritoneopleural communication associated with unsuspected and asymptomatic hepatitis C-induced cirrhosis of the liver with portal hypertension.

Portal hypertension.

Portal hypertension is the main complication of cirrhosis and is responsible for its most common complications: variceal hemorrhage, ascites, and portosystemic encephalopathy. Portal hypertension is the result of increased intrahepatic resistance and increased portal venous inflow. Vasodilatation (splanchnic and systemic) and the hyperdynamic circulation are hemodynamic abnormalities typical of cirrhosis and portal hypertension. Gastroesophageal varices result almost solely from portal hypertension, although the hyperdynamic circulation contributes to variceal growth and hemorrhage. Ascites results from sinusoidal hypertension and sodium retention, which is in turn secondary to vasodilatation and activation of neurohumoral systems. Hepatic hydrothorax results from the passage of ascites across the diaphragm and into the pleural space. The hepatorenal syndrome represents the result of extreme vasodilatation with an extreme decrease in effective blood volume that leads to maximal activation of vasoconstrictive systems, renal vasoconstriction, and renal failure. Spontaneous bacterial peritonitis is a potentially lethal infection of ascites that occurs in the absence of a local source of infection. Portosystemic encephalopathy is a consequence of both portal hypertension (shunting of blood through portosystemic collaterals) and hepatic insufficiency resulting in the accumulation of neurotoxins in the brain.

Proliferative and histologically malignant struma ovarii: a clinicopathologic study of 54 cases.

We reviewed 54 cases of struma ovarii with histologic features diverging from the normal pattern of benign thyroid tissue. These 54 lesions were divided into proliferative struma (41 cases) and malignant struma (13 cases). The patients diagnosed with proliferative struma ovarii ranged in age from 18 to 84 years (average, 44 years). The most common clinical findings among the proliferative struma patients were a mass (58%) and acute abdominal pain (12%). Preoperative evidence of hyperthyroidism was noted in three of the patients with proliferative struma, whereas one additional patient presented with ascites and hydrothorax ("pseudo-Meigs' syndrome"). Proliferative struma differed from the usual struma ovarii in that they comprised areas of densely packed follicles or papillary formations that raised the possibility of malignancy. However, none of the lesions that we have designated as proliferative struma ovarii showed histologic evidence of overlapping "ground glass" nuclei, vascular space invasion, or mitotic activity that would have supported an unequivocal diagnosis of malignancy. None developed metastases or recurrent disease. The 14 malignant struma ovarii manifested the classical features of thyroid carcinoma (including the presence of overlapping "ground glass" nuclei lining papillary formations and vascular space invasion). Patients with malignant struma ovarii ranged in age from 30 to 77 years (average, 50 years). Their clinical presentations included a mass (78%) and acute abdominal pain (22%). One patient had clinical and laboratory evidence of hyperthyroidism. On follow-up, one patient had persistent disease with peritoneal involvement, but distant metastases did not develop in any of these patients. A diagnosis of malignant struma ovarii should be reserved for lesions that exhibit the full range of changes seen in thyroid carcinoma arising in the cervical thyroid. By requiring that these rigid criteria be adhered to, the diagnosis of malignant struma ovarii will probably become less frequent as the more commonly encountered proliferative struma ovarii are recognized.

Transjugular intrahepatic portosystemic shunts (TIPS): a decade later.

Since the introduction of transjugular intrahepatic portosystemic shunt (TIPS) 10 years ago, it has been used increasingly in the management of portal hypertension and its complications. TIPS is now considered the procedure of choice for management of refractory variceal bleeding. Its role in the management of refractory ascites, hepatic hydrothorax, hepatorenal syndrome, and hepatopulmonary syndrome still awaits further prospective studies. The two main complications of TIPS are hepatic encephalopathy and shunt malfunction. Generally, TIPS stenosis or occlusion is a major drawback requiring routine surveillance of TIPS with doppler ultrasound. Venography with balloon dilation of the stent or placement of serial or parallel stents may be required in some cases. Promising modalities of preventing TIPS malfunction (e.g., brachy-therapy, covered stents, or anti-platelet derived growth factor) are currently being investigated.

Perforations of the esophagus from gunshot wounds.

Fifteen cases of gunshot wounds of the esophagus seen between the years 1970 and 1978 were reviewed, eight involving the cervical esophagus and seven involving the thoracic portion. Most common symptoms were pain, neck tenderness, dyspnea, and dysphagia. Signs observed were subcutaneous emphysema, crepitations, fever, and leukocytosis. Plain X-rays showed pneumomediastinum, hydrothorax, and pneumothorax. Perforations were confirmed by barium studies in 12 patients. Injuries in the cervical portion were treated by prompt exploration, closure of the defect, and drainage. There were no deaths in this group. Thoracic injuries were treated by prompt thoracotomy except in one patient, for whom the diagnosis was not made until 22 hours after the injury; his was the only death in this series. Because of the extensive tissue involvement in gunshot wounds, primary repairs of thoracic esophageal perforations have a high incidence of failure. Defunctionalization of the esophagus, through ligation of the distal esophagus, gastrostomy, and cervical esophagostomy, has provided a safer method. Use of a double strand of absorbable Dexon to ligate the distal esophagus made a second thoracotomy for removal of the ligature unnecessary. We have adopted routine use of hyperalimentation, avoiding the need for feeding jejunostomy.
