Correção laparoscópica de hérnia diafragmática traumática crônica

Diaphragmatic hernia secondary to blunt or penetrating trauma is rarely by itself a fatal event. However, if unpercieved, it may lead to severe complications caused by herniation of abdominal contents to the ethorax. Blunt trauma related to car accidents is the most frequent cause of diaphragmatic hernias. Associated injuries are frequently observed, provoked by severe traumas of great impact. These blunt trauma hernias occur mainly on the left side due to abdominal anatomy, since the liver is usually located on the right side. When injuries are observed on the right they tend to be more severe, generally related to major trauma of solid organs. Less frequently diaphragmatic hernias may be bilateral. The management of diaphragmatic injury would appear to be a simple matter of suturing the defect. However, peroperative diagnosis can be difficult and even at the time of surgery some diaphragmatic injuries can be overlooked if carefull exploration is not done. Associated injuries tend to divert attention from the diaphragmatic injury. Laparoscopic diagnosis and repair have been described with successfull. Laparotomy or thoracotomy can be employed for surgical repair of traumatic diaphragmatic hernias. Standard (laboratory/imaging) examinations may fail to make the diagnosis. Recently, the laparoscopic approach has proved useful for more precise evaluation of such injuries, very often allowing immediate repair of these lesions.

Hérnia diafragmática traumática crônica e fístula gastropleurocutânea

Traumatic diaphragmatic hernia is defined as a laceration of the diaphragm with an abdominal viscera herniation into the thorax. It is usually asymptomatic, with the exception of the cases with obstruction, strangulation, necrosis or perforation of the herniaded viscera. It is classified as acute, latent or chronic, in accordance with the evolutive period. At the latent phase, symptoms are indefinite and the radiological signals, which are suggestive of thoracic affections, are frequent and can induce a diagnosis error, leading to inadequate treatment.This article presents a case of chronic traumatic diaphragmatic hernia which was complicated by a gastricpleuralcutaneous fistula, due to an inadequate thoracic drainage. Considering that this is a chronic affection with an unquestionable surgical indication, due to the complications risk, it is essential to have a detailed diagnostic investigation, which aims at both avoiding an intempestive or inadequate therapeutics behaviour and reducing the affection morbimortality. Recently, the videolaparoscopic approach has proved to be more precise when compared to the other diagnostic methods, by direct visualization of the diaphragmatic laceration, allowing its correction by an immediate suture.

Banda gástrica ajustável laparoscópica: alternativa técnica

In these paper we are presenting a technical alternative to laparoscopic adjustable gastric banding. From January 1999 to April 2000, 60 patients with mean body mass index (BMI) of 40,7 kg/m2 underwent laparoscopic adjustable gastric banding. The new technique is performed in two steps. In the first step, an isolation instrument (laparoscopic finger) is inserted through the lesser sac, next to the junction of diaphragmatic crura, including the lesser omentum in order to pull the band catheter. The second step separates the lesser omentum from the right side of the stomach.There was no mortality and the morbidity was 11,6% (1 slippage of the band and 6 trocar port seroma). The new technique was performed in all patients with no conversion to open procedure. We didn't have respiratory complications. This technical alternative is safe and easily performed, helping to prevent transoperative perforations.

Hérnia diafragmática traumática

Traumatic diaphragmatic hernia is an uncommon but important problem in the patient with multiple injuries. Since diaphragmatic injuries are difficult to diagnose, those that are missed may present with latent symptoms of bowel obstruction and strangulation. The same may occur in the patients with stab wounds to the lower chest. Traumatic diaphragmatic hernia should be suspected on the basis of an abnormal chest radiograph in the trauma victim with multiple injuries. This article discuss about history, epidemiology, clinical signs and symptoms, diagnostic modalities, treatment and complications.

Videolaparoscopia no trauma abdominal

Despite the use of laparoscopy in abdominal trauma for several decades, it was only after the advent of video chip camera that an explosion of interest ocurred, giving rise to possibilities and perspectives not only in diagnosis but also in therapeutics. In trauma, its use has been gradually defined and experience has shown the benefits of the method in early diagnosis of visceral injuries as well as avoiding unnecessary laparotomies. Trauma laparoscopy is a safe method, can reduce negative and nontherapeutic laparotomies. The worrisome failure of laparoscopy to detect gastrintestinal injuries, specially small bowel lesions can be avoided with a mandatory and apropriated "run bowel" exploration. We believe that in hemodinamically stable patients, video laparoscopy is safely indicated in some situations in trauma, such as evaluation of diaphragmatic injuries in thoraco abdominal stab wounds and tangential gunshot wounds of anterior abdominal wall.

Hérnia de Morgagni simulando lipoma torácico

The Morgagni hernia is the rarest kind of diaphragmatic hernia , occurring in 3% of all cases. It consists of the protrusion of the abdominal content into the thoracic cavity including omentum and transverse colon, among others. It is more common in the right side and appears more frequently after 40 years of age or after a raise in the intra-abdominal pressure. Patients with Morgagni hernia are usually asymptomatic. In the X-ray it appears like an opaque image in the cardiophrenic angle.Surgical correction is the treatment of choice for this conditions. We present one case of Morgagni hernia successfully treated.

Hérnia de bochdalek em adulto

Bochdalek´s hernia is a congenital malformation of the posterolateral diaphragm region. It is more common on the left and more frequently seen in newborns and rare in adults, with over a few 100 reported cases. We present a case of Bochdalek´s hernia in a 49-year-old patient with long term dyspeptic symptoms. The upper endoscopy showed a gastric fundus herniation sliding into the chest through the diaphragmatic defect. The patient also presented with a rare pulmonary malformation diagnosed during surgery. It was corrected through thoracic approach with no other complications.

Hérnia intercostal transdiafragmática após fratura espontânea de costelas secundária à crise de tosse

One case of transdiafragmatic intercostal hernia after intense coughing fit followed by rib fractures in patient with history of pneumonia is presented. He had a severe coughing fit, developed a right toracoabdominal hematoma and then a tumor that was gradually enlarging. Image exams confirmed the diagnosis. Treatment consisted of surgical repair with the use of a polypropylene prosthetic mesh. It is a rare type of hernia. Only four cases were found in literature. The sooner the disease is diagnosed and treated the better the prognoses will be since it will prevent hernia from strangulation and incarceration.

Submandibular gland excision

OBJECTIVE: to analyze the value of fine needle aspiration and the rates of postoperative complications in patients undergoing resection of the submandibular gland. METHODS: we analyzed the records of patients treated with resection of the gland from January 1995 to December 2008. The data collected included age, gender, findings on clinical history, surgical procedure, results of fine needle aspiration (FNA), pathological diagnosis and complications. RESULTS: 117 patients were studied, aged 12-89 years (mean 48), 70 women and 47 men. Thirty-nine patients (33.3%) were affected by inflammatory diseases (28 patients with lithiasis), 70 had benign tumors, and malignant tumors, eight. Regarding FNA, the sensitivity and specificity were 85.7% and 100%, respectively. Nine patients (7.7%) had temporary paralysis of the marginal mandibular nerve and one had permanent paralysis. CONCLUSION: resection of the submandibular gland is a safe procedure, with low complication rates.

Spinal cord compression in cattle after the use of an oily vaccine

An outbreak of compressive myelopathy in cattle associated with the improper use of an oil vaccine is described. Neurological signs were observed in 25 out of 3,000 cattle after 60 days of being vaccinated against foot and mouth disease. The clinical picture was characterized by progressive paralysis of the hind limbs, difficulty in standing up, and sternal recumbency during the course of 2-5 months. A filling defect between the L1 and L3 vertebrae was seen through myelography performed in one of the affected animals. A yellow-gray, granular and irregular mass was observed in four necropsied animals involving the spinal nerve roots and epidural space of the lumbar (L1-L4) spinal cord; the mass was associated with a whitish oily fluid. This fluid was also found in association with necrosis of the longissimus dorsi muscle. Microscopic changes in the epidural space, nerve roots, and spinal musculature were similar and consisted of granulomas or pyogranulomas around circular unstained spaces (vacuoles). These spaces were located between areas of severe diffuse hyaline necrosis of muscle fibers and resembled the drops of oil present in the vaccine.

Type C botulism in swine fed on restaurant waste

The paper addresses the epidemiologic data of the death of pigs during the period of 2002 to 2009 following the ingestion of botulinum neurotoxin type C. This neurotoxin was present in food residues originating from restaurant and hotel kitchens, stored in barrels without shelter from the sun and administered in a collective trough without prior thermal treatment. Animals which died at different ages showed clinical signs of botulism characterized by flaccid paralysis, weight loss, anorexia, weakness, lack of coordination, locomotion difficulties with the evolution of lateral recumbency with involuntary urination and defecation. No alterations were observed at postmortem and histological examination. The bioassay with serum neutralization in mice was carried out on samples of intestinal contents from pigs affected and revealed the presence of large quantities of botulinum toxin type C.

Acute fasciolosis in cattle in southern Brazil

This study describes the epidemiological and pathological aspects of an outbreak of acute fasciolosis in cattle in southern Brazil. Fifteen out of 70 three-year-old pregnant cows lost weight in the 30-40 days prior to calving. Clinical signs included diarrhea, weakness, mild anemia and jaundice. Dark yellow fluid in the abdominal cavity was observed at necropsy. Fibrin and clotted blood were adhered to the pericardium and lung, primarily in the diaphragmatic lobes. The liver was enlarged, and the capsular surface was irregular with clear areas and petechiae. At the cut surface, the liver was irregular, firm and edematous, and several hemorrhagic channels could be observed. Areas of fibrosis through the parenchyma and whitish thrombi occluding the great vessels were also observed. The livers of 10 cows that not died were condemned at slaughter for lesions of fasciolosis similar to those observed at necropsy. Microscopically, the liver showed areas of coagulation necrosis, extensive hemorrhages in the streaks or foci and disruption of the parenchyma with neutrophil and eosinophil infiltration. Fibrosis and bile duct proliferation were also observed. Immature Fasciola hepatica flukes were observed in the parenchyma surrounded by degenerated hepatocytes, neutrophils, eosinophils, and hemorrhages. The outbreak occurred on a farm located in an area endemic for fasciolosis, although the acute form of the disease is not common in cattle in this region. It is likely that the cows were infected by F. hepatica metacercariae released in the late fall or early spring in the rice stubble where the herd was grazing prior to calving. Although mortality due to fasciolosis in cattle is infrequent, outbreaks can occur and treatments that are effective in both the immature and adult forms of the parasite should be administered to prevent economic losses.

Transitional cell carcinoma of urinary bladder with metastasis in lumbar vertebrae and spinal cord compression in an ocelot(Leopardus pardalis)

This paper reports a case of nonpapillary and infiltrative transitional cell carcinoma (TCC) of the urinary bladder with metastasis of lumbar vertebrae and spinal cord compression in an adult female ocelot (Leopardus pardalis), from the Mato Grosso state, Brazil. The ocelot had pelvic limb paralysis and skin ulcers in the posterior region of the body and was submitted to euthanasia procedure. At necropsy was observed a multilobulated and irregular shaped, yellowish to white nodule in the urinary bladder. The nodule had a soft consistency and arised from the mucosa of the urinary bladder extending throughout the muscular layers and the serosa. Nodules of similar appearance infiltrating the vertebral column the at L6 and L7 vertebrae with corresponding spinal canal invasion were also observed. The histological evaluation showed epithelial neoplastic proliferation in the urinary bladder with characteristics of nonpapillary and infiltrative TCC, with positive immunohistochemical staining for pancytokeratin, and strong immunostaining for cytokeratin of low molecular weight, and weak or absent labeling for high molecular weight cytokeratin. This is the first report of TCC of urinary bladder in ocelot in Brazil.

Rare adverse events associated with oral poliovirus vaccine in Brazil

Oral poliovirus vaccine (OPV) developed by A. Sabin has been effectively used to control poliomyelitis in Brazil, and the last case with the isolation of a wild poliovirus strain occurred in March 1989. Although the vaccine controlled the circulation of wild strains and poliomyelitis cases associated with these strains were not detected during the last eight years, rare cases classified as vaccine-associated paralytic poliomyelitis (VAPP) have been detected. Molecular characterization studies of poliovirus strains isolated from VAPP cases and from healthy contacts have confirmed that the isolates are derived from the Sabin vaccine strains and also detected genomic modifications known or suspected to increase neurovirulence such as mutations and recombination. The molecular characterization of polioviruses isolated during the last eight years from paralysis cases classified as Guillain-Barré (GBS) syndrome and transverse myelitits (TM), and from facial paralysis (FP) cases also confirmed the vaccine origin of the strains and demonstrated mutations known to increase neurovirulence. Analysis of the epidemiologic data of these GBS, TM and FP cases demonstrated that in most of them the last OPV dose was given months or years before the onset of the disease and the isolation of the polioviruses. The temporal association between the isolation of these strains and the GBS, TM and FP suggested that the Sabin vaccine-derived poliovirus strains could also rarely trigger the diseases.
