Sample records for abdominal cavity

  1. Radiography of the abdominal cavity

    Radiography is a very important part of the diagnostic procedure in many small animal diseases. Technically perfect X-rays are essential for the exact diagnosis. The general appearance of the abdominal cavity should be evaluated at first, e.g. the overall contrast and the definition of the visualized organs. Then particular attention should be paid, if there is any peritoneal effusion or free air in the peritoneal cavity. Subsequently each radiographically visible organ has to be evaluated for its position, size, shape and radiographic density

    Full Text Available 85 patients with abscesses of abdominal cavity (AAC at the age from 5 to 15 years old were observed. 37 (43.5% patients had unformed and 48 (56.5% patients had formed intra-abdominal abscesses. Devised methods of complex investigation were used to diagnose postoperative abscesses of the abdominal cavity; they included the index of blood toxicity (IBT and the index of spontaneous agglomeration leukocytes (ISAL in combination with dynamic purposeful using of searching ultrasound sonography and clinical signs. The complex diagnostics including ultrasound sonography, indexes of blood toxicity, spontaneous agglomeration of leucocytes and clinical signs can allow us significantly improve the effectiveness of diagnosis of intra-abdominal abscesses in the early stages after surgical operation regarding to appendicular peritonitis (AP in children and to choose the optimal method of surgical treatment.

  3. Abdominal cavity exploration with kinetic scintimaging

    Nuclear medicine procedures are being utilized in an increasing variety and number of intra-abdominal clinical problems. These non-invasive intra-abdominal exploratory scintimaging procedures are often dynamic or kinetic in nature, i.e. revealing primarily functional information even to the point of employing adjunctive drugs and multiple simultaneous radiotracers. The advent of correlative non-invasive diagnostic imaging modalities has thus far largely complemented abdominal nuclear medicine procedures. The luminal gastro-intestinal tract has yielded to investigation with radiotracers with procedures now widely employed to study gastric function, gastro-oesophagal reflux and intestinal bleeding. The role of hepatic and splenic reticuloendethelial compartment imaging has been strengthened by increased dependability, and remains as the first line screening test for a variety of suspected intrahepatic lesions, especially neoplasia. The recent introduction of improved hepatobiliary radiotracers, mostly iminodiacetic acid derivatives, has considerably expanded the scope of diagnostic investigations of the liver, especially in problems of jaundice and acute cholecystitis. Pancreatic imaging continues to be a disappointment and at best is only adjunctive to correlative imaging procedures. Some hope may be seen in the recent reports of successful pancreatic imaging with positron emission tomography utilizing labelled amino-acid derivatives. Diffuse abdominal processes, especially abcesses and suspected infection, have been efficaciously approached with 67Ga citrate and also, more recently, 111-In-labelled leucocytes. Many of these advances and applications have also been readily applicable to pediatric problems. (author)

    Full Text Available Ectopic hepatocellular carcinoma (HCC is a very rare clinical entity that is defined as HCC arising from extrahepatic liver tissue. This report presents a case of ectopic multiple HCC arising in the abdominal cavity. A 42-year-old otherwise healthy male presented with liver dysfunction at a general health checkup. Both HCV antibody and hepatitis B surface antigen were negative. Laboratory examination showed elevations in serum alpha-fetoprotein and PIVKA-II. Ultrasonography and computed tomography revealed multiple nodular lesions in the abdominal cavity with ascites without a possible primary tumor. Exploratory laparoscopy was performed, which revealed bloody ascites and multiple brown nodular tumors measuring approximately 10 mm in size that were disseminated on the perineum and mesentery. A postoperative PET-CT scan was performed but it did not reveal any evidence of a tumor in the liver. The tumors resected from the peritoneum were diagnosed as HCC. The present case of HCC was thought to have possibly developed from ectopic liver on the peritoneum or mesentery.

  8. The MRI of extraadrenal pheochromocytoma in the abdominal cavity

    The purpose of this study was to summarize the MR appearances of extraadrenal pheochromocytoma in the abdominal cavity and evaluate the capabilities of MRI in diagnosis of the tumor. Eleven consecutive patients with an extraadrenal pheochromocytoma in abdominal cavity who underwent preoperative 0.5 T (n = 5) or 1.5 T (n = 6) superconductor MRI and had a surgical resection were enrolled in the study. The MR scanning protocol included axial T2-weighted imaging with or without fat-suppressed sequences, axial and coronal uncontrast and contrast T1-weighted sequences with or without fat suppression. The extraadrenal pheochromocytomas were found in retroperitoneum (n = 5), the urinary bladder (n = 1), the pelvis (n = 1), the right prerenal area (n = 1), the renal hilus (n = 1), the left paramusculus psoas major (n = 1) and liver (n = 1). The mean maximal diameter of tumors was 55.9 mm (range 17.8-162.2 mm). The high signal intensity was seen on T2-weighted imaging in all tumors compared to muscle or liver, especially with fat suppression. The intratumoral septa and capsules were shown in 63.6% and 72.7% of cases, respectively, which had low signal intensity on T2-weighted imaging. These relative characteristics may be helpful for qualitative diagnosis of extraadrenal pheochromocytomas with MRI. Other usefulness of MRI was to locate the position, to decide the range of tumors and to show well the relationship between the tumor and near structures

  9. The CT findings of non-Hodgkin's lymphoma in the abdominal cavity of children

    Objective: To evaluate CT diagnostic value of non-Hodgkin's lymphoma in the abdominal cavity of children. Methods: CT manifestations of 14 cases of non-Hodgkin's lymphoma in the abdominal cavity of children were retrospectively analyzed. The patients included 8 boys and 6 girls, aging from 3-14 years. Ten cases were confirmed by operation and pathology, and 4 cases were confirmed by biopsy. Results: The main CT signs of non-Hodgkin's lymphoma in the abdominal cavity of children showed as follows: (1) 14 cases showed multiple huge irregular mass in abdominal cavity; (2) Bowel-wall thickened in 6 cases; (3) In 6 cases, enlarged mesenteric and retroperitoneal lymph nodes embodied the vessels of mesenteric and celiac trunk. This finding was so-called 'sandwich' sign; (4) Bowel demonstrated the sign of aneurysmal dilatation in 4 cases; (5) Two cases showed 'air-fluid level' sign in intestinal canal; (6) Three cases involved other adjacent abdominal organs, such as spleen in 1 case, kidney in 1 case, and liver in 1 case; (7) One case showed incomplete intestinal obstruction; (8) After contrast medium administration, the masses in 13 cases showed moderate enhancement; (9) Four cases showed ascites in abdominal cavity. Conclusion: CT is very useful for diagnosing and mapping the extension of non-Hodgkin' s lymphoma in the abdominal cavity of children

    Abdominal enterocele is a result of entering abdominal organs into peritoneal pockets and folds through the holes in mesenterium or into the adjoining cavities through defects in their walls. Enteroceles are localized at the sites where one segment of the gastrointestinal tract passes into another, in a pocket behind the cecum and sigmoid, between mesenteric layers of small intestine and colon, in the holes of mesenterium of vermiform appendage, gastrocolic and falciform ligaments, pockets and holes of broad ligament of the uterine, omental foramen, rectouterine excavation, and diaphragmal defects. We observed a 26 year old woman with enterocele entrapment in the abdominal cavity complicated by necrosis of part of the small intestine. PMID:26031155

    Guyon, Laurie; Claude Lesage, Jean; Betrouni, Nacim; Mordon, Serge

    2012-03-01

    A homogeneous illumination of intra-abdominal organs is essential for successful photodynamic therapy of the abdominal cavity. Considering the current lack of outstanding light-delivery systems, a new illumination procedure was assessed. A rat model of peritoneal carcinomatosis was used. Four hours after intraperitoneal injection of hexaminolevulinate, a square illuminating panel connected to a 635-nm laser source was inserted vertically into the abdominal cavity. The abdominal incision was sutured and a pneumoperitoneum created prior to illumination. Light dosimetry was based on the calculation of the peritoneal surface by MRI. The rats were treated with a light dose of 20, 10, 5 or 2.5 J/cm2 administered continuously with an irradiance of 7 mW/cm2. The homogeneity of the cavity illumination was assessed by quantification of the photobleaching of the tumor lesions according to their localization and by scoring of that of the liver and of the bowel immediately after treatment. Photobleaching quantification for tumor lesions relied on the calculation of the fluorescence intensity ratio (after/before treatment) after recording of the lesions during blue-light laparoscopy and determination of their fluorescence intensity with Sigmascan Pro software. The procedure led to a homogeneous treatment of the abdominal cavity. No statistical difference was observed for the photobleaching values according to the localization of the lesions on the peritoneum (p=0.59) and photobleaching of the liver and of the intestine was homogeneous. We conclude that this procedure can successfully treat the major sites involved in peritoneal carcinomatosis.

    Uterine perforation is a serious problem which can happen after intrauterine device (IUD) insertion. Migration of the IUD to the pelvic and abdominal cavity or adjacent organs may be seen following perforation of the uterus. Migration of an IUD to a far intra-abdominal site is extremely rare. The patient reported here had undergone an IUD placement 30 years previously and had no problems during this period. The IUD was incidentally found at the left upper quadrant of the abdomen in the mesent...

  19. Computer tomography in the diagnosis of disease of the abdominal cavity and retroperitoneal space

    It is ascertained that computer tomography of abdominal cavity organs is a promising diagnostics technique in cases when conventional radiography does not provide required information, especially for the diseases of liver parenchyma. The application of contrast substances enhances the detection of pathological changes. New contrast substances should be seeked for to enhance diagnostic capabilities of the computer tomography and to increase the difference between radiation absorption coefficient

Differences from other avian species and unique features of the ostrich are briefly discussed.

  5. Is It Worthwhile to Fully Evaluate the Stomach in Every Ultrasound Examination of the Abdominal Cavity?

    To evaluate the usefulness of abdominal sonography in the fasting state with no hypotonic agents in the detection and exclusion of gastric lesions. One-hundred patients with normal upper gastrointestinal endoscopy, 94 patients with a major gastric abnormality (including 59 intraluminal tumors, three submucosal masses, 29 ulcers, two polyps and one hypertrophied gastric mucosa) and 75 patients with minor gastric abnormalities (mainly gastritis) were enrolled into the study. Of the 100 normal patients, ultrasound showed four false positive results with 96% specificity of the examination. Within the major gastric lesion group, ultrasound was true positive in 55 of 59 tumors, 15 of 29 ulcers, three of three submucosal masses and the case of giant gastric mucosa. It was negative in the detection of gastric polyps. It could detect only 8% of minor gastric abnormalities. Abdominal sonography in the fasting state, if carefully performed, is sufficiently accurate in detection and exclusion of major gastric lesions. Therefore, although it cannot replace endoscopic and barium studies of the stomach, careful evaluation of the stomach is recommended in every sonographic evaluation of the abdominal cavity

  9. Pathomorphologic aftereffects of chronic irradiation with γ-neutron source incorporated in the abdominal cavity (communication 2)

    The results were presented of radiometric and morphological studies of the viscera of dogs and sheep who lived 5 to 7 years with the Hertz-IR type γ-neutron standard radiation sources, implanted in the abdominal cavity. The most coarse dystrophic and sclerotic changes were found in the visceral sites adjacent to the radiation source or near it. It was suggested that spermatogenesis disorders resulting from chronic low-dose irradiation were due to not only the immediate action of ionizing radiation, but to total disorders of the trophicity of irradiated body as well

    Ozone is an oxidizing agent possessing potent in vitro microbicidal capacity. This study was designed to address the extent to which irrigation of the contaminated abdominal cavity using a saline solution primed with ozone is effective in reducing morbidity and mortality. Gelatin capsules containing different quantities of a premixed slurry of filtered human fecal material were implanted in the peritoneal cavities of a preliminary series of rats. Three inocula concentrations were selected for later experiments, based upon their ability to produce morbid consequences: (1) high (100% 1-day mortality), (2) medium (70% 3-day mortality, 100% abscess rate in survivors), and (3) low (100% 10-day survival, 100% abscess rate). Fecal and abscess bacteriology were similar in all rats. The peritoneal cavities of 240 rats then underwent fecal-capsule implantation (three groups of 80 rats/inoculum concentration). At celiotomy 4 hours later, equal numbers of rats from each group were randomly assigned to one of four protocols: (1) no irrigation, (2) normal saline irrigation, (3) saline-cephalothin irrigation, and (4) ozonated saline irrigation. Each treatment lasted 5 minutes, using 100 ml of irrigation fluid. Mortality was significantly reduced when, in lieu of no irrigation, any of the irrigation solutions were used. Additionally, ozonated saline statistically proved the most effective irrigating solution for reducing abscess formation in survivors.

    2015-10-01

    During 2011 - 2014 yrs in Surgical Clinic of The First City Clinic (Poltava) a relaparotomy was performed in 127 patients. There was established, that relaparotomy constitutes the only one procedure for such life threatening states, as intraabdominal bleeding, ileus in a decompensation stage, eventration, progressing peritonitis, abdominal compartment syndrome stages III - IV. The rate of relaparotomy application after performance of urgent operative interventions is bigger than after planned operations (ratio 4:1). Individual estimation of a state and choice of optimal surgical tactics during primary and secondary operative interventions are needed to improve the results of treatment. PMID:26946667

  13. Fate of gamma-interferon-activated killer blood monocytes adoptively transferred into the abdominal cavity of patients with peritoneal carcinomatosis

    Five patients with colorectal cancer widely metastatic to peritoneal surfaces have been treated i.p. with infusions of autologous blood monocytes made cytotoxic by in vitro incubation with human gamma-interferon. The monocytes were purified by a combination of cytapheresis and counter-current centrifugal elutriation procedures; each week approximately 350 million activated monocytes were given to patients as adoptive immunotherapy by a single i.p. instillation. On the eighth cycle of treatment the trafficking of i.p. infused blood monocytes was studied in two patients by prelabeling the cells with 111In. These activated cells became distributed widely within the peritoneal cavity. Two and 5 days after infusion their position within the peritoneum had not changed. When peritoneal specimens were obtained 36 h after 111In-labeled monocyte infusion, labeled monocytes were demonstrated to be associated with the serosal surfaces by autoradiographic analysis. Scintiscanning structures outside the abdominal cavity revealed that 111In-labeled monocytes infused i.p. did not traffic to other organs during the 5 days of the study. We conclude that i.p. adoptive transfer of autologous killer blood monocytes is an effective way of delivering these cytotoxic cells to sites of tumor burden on peritoneal surfaces in these cancer patients

  14. Content of the canceroembryonal antigen in tumours of the organs of the abdominal cavity and the retroperitoneal space

    The concentration of the canceroembryonal antigen (CEA) has been determined in vitro by the radioimmunological analysis of the blood plasma of 70 donors and 130 patients with malignant tumours of the intestine (6 persons), stomach (77), with relapsing gastric carcinoma (12), tumours of the pancreas (7), retroperitoneal space (18) and with inflammatory disease of the gastrointestinal tract (12). It is established that the radioimmunological test in vitro for CEA can be used not only for primary diagnosis of cancer of the rectum but also as a substantial supplement to the clinical diagnosis of carcinoma of the stomach and the pancreas. A relationship revealed between the rise in the content of CEA and the extent of malignancy provides additional information for correct diagnosing the stage of gastric carcinoma and a choice of an adequate method of treatment. Tolerance of the CEA level in the blood in retroperitoneal tumours and inflammatory diseases of the gastrointestinal tract may serve as a criterion for differential diagnosis of malignant newgrowths in the abdominal cavity

    1999-08-01

    Full Text Available Foram avaliados os resultados tardios da colocação de cálculos biliares humanos, de colesterol, na cavidade peritoneal de ratos. Constituíram-se cinco grupos: cinco ratos foram apenas laparotomizados com manuseio da cavidade; cinco foram laparotomizados e receberam um ponto com fio monofilamentar cinco zeros no sulco paracólico direito e mesentério; dez receberam cálculos que foram deixados livres na cavidade peritoneal; em dez, os clculos foram fixados no sulco paracólico direito e, finalmente, dez tiveram clculos fixados no mesentério. Os animais foram mortos após cinco meses de pós-operatório quando se observou a cavidade abdominal e foi coletado material para estudo histopatológico. Concluiu-se que os cálculos não foram absorvidos, desenvolveram uma reação peritoneal do tipo corpo estranho com formação de plastrão e foram envolvidos por tecido fibroso e células inflamatórias.It was evaluated the late results of human gallstones placed into peritoneal cavity of rats. Five groups were created. In the first (group A five rats were submitted only to laparotomy and handling of abdominal cavity, in the second (group B five rats were submitted to laparotomy and a stitch was placed into right abdominal wall and in mesenterium between the ileus and cecum, in the third (group C ten rats received a gallstone left free into abdomen, in the fourth (group D ten rats received a gallstone fixed into right abdominal wall and in the fifth (group E ten rats received a gallstone fixed in mesenterium between the ileus and cecum. One rat in each group was selected to be use as a pilot and were re-laparotomized after 1 month and 3 months, in order to look for any possible alteration. All rats were dead after five months when the abdominal cavity was observed and specimens were collected around the gallstones to histopathology. ln groups A and B there were not important macroscopic alterations. The gallstones were not absorved in groups C, D

  2. An Improved Approach to External Beam Radiation Therapy for Intra-Abdominal Cavity Lesions for Rural Cancer Centers

    Radiation therapy of abdominal lesions is problematic at best. The proximity of highly critical structures, tumor locations, and necessary margins combine to make prescription dose delivery with conventional 3-dimensional (3D) conformal techniques difficult. Others have tried to overcome these hurdles with newer modalities including intra-operative radiation therapy (IORT), intensity modulated radiation therapy (IMRT), and heavy particle irradiation. These techniques have had moderate success but are not readily available and are therefore limited in application. These factors have lead to the development of a modified, noncoplanar 4-field box technique that demonstrates significant improvement in critical structure sparing, i.e., kidney(s), bowel, and liver doses reduced while simultaneously improving isodose coverage to the target

    Wound dehiscence is a surgical complication in which the wound ruptures along the surgical suture with abdominal cavity bowel displacement. It is observed in 0.2-6% of operated patients. The extensive wound is a gateway for infection. Moreover, increased secretion of serous fluid induces a hygienic problem and may lead to secondary skin infections or bedsores. The negative pressure wound therapy (NPWT) system is an innovative therapeutic method. It perfectly executes the TIME strategy, receiving more and more recognition. The study presented a case of a 62-year old male patient after several consecutive wound dehiscence episodes who was primarily treated for rectal cancer by means of low anterior resection of the rectum. Due to acute respiratory insufficiency after several operations, wound necrosis with dehiscence was observed. Considering the high risk of perioperative death we abandoned surgical treatment and introduced conservative management using negative pressure wound therapy until the patient's health improved. Literature regarding the above-mentioned issue was also reviewed. PMID:26816408

    Abdominal pain is one of the most common complaints by patients, and assessment of abdominal pain and associated symptoms can be challenging for home healthcare providers. Reasons for abdominal pain are related to inflammation, organ distention, and ischemia. The history and physical examination are important to narrow the source of acute or chronic problems, identify immediate interventions, and when necessary, facilitate emergency department care.

  8. Abdominal trauma

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

  9. Abdominal trauma

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

  11. Abdominal Sepsis.

    De Waele, Jan J

    2016-08-01

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    Full Text Available Abdominal compartment syndrome with increased abdominal pressure resulted in multi-organ dysfunctions can be lethal in children. The open abdomen procedure intentionally leaves the abdominal cavity open in patients with severe abdominal sepsis and abdominal compartment syndrome by temporarily relieving the abdominal pressure. We reported our experience of open abdomen procedure in successfully treating a 4-year old boy with abdominal compartment syndrome caused by severe fungal peritonitis and sepsis after gastric perforation.

  16. Abdominal Burkitt lymphoma

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

  17. Abdominal Burkitt lymphoma in children : CT finding

    To evaluate the CT findings of Burkitt's lymphoma involving the abdomen in children We retrospectively analyzed the abdominal CT of ten children who presented with abdominal symptom. They were confirmed by operation in two cases and by fine needle aspiration biopsy in eight to be suffering from Burkitt's lymphoma. We also abdominal ultrasonography(USG)(n=10) and carried out small bowel follow-through examination(SBS)(n=5). Analyses focused on features of the abdominal mass : bowel wall thickening, ascites, lymphadenopathy, and the involvement of intra-abdominal solid organ. Abdominal CT at the time of presentation showed a huge conglomerated mass encasing segments of small bowel and also peripherally displacing bowel loops(n=9), bowel wall thickening(n=10), and ascites(n=10). In three of these cases, we were able to see tumor necrosis and cavity formation. Extensive infiltration into mesenteric fat and obliteration of tissue plane made it impossible to identify on CT the margin of the tumor and the presence of mesenteric lymphadenopathy. In four patients, sonography showed enlarged mesenteric lymph nodes(15-20mm), and in three, retroperitoneal lymph nodes(5mm, 10mm, 12mm in long dimension) were detected on CT and USG. Abdominal CT can reveal the characteristic imaging features of Burkitt's lymphoma in children. These are a huge conglomerate mass with or without cavity formation, that encases the small bowel and infiltrates the mesentery, ascites, and the relatively spared retroperitoneal lymph nodes

  1. Abdominal trauma

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

    con una fuente emisora de calor (resguardo caliente. Diversos autores han descrito la difusión del N2O para cavidades cerradas por métodos como cromatografia gaseosa y analizador de gases, que no permiten un estudio macroscópico detallado del gas. El presente estudio tubo como objetivo la filmación macroscópica en el espectro infrarrojo de la difusión de N2O, utilizado en anestesia inhalatoria, para la cavidad peritoneal de ratones sometidos a pneumoperitoneo de 20 mmHg con aire ambiente. MÉTODO: Los animales fueron divididos en tres grupos, de acuerdo con el anestésico utilizado: I- Control venoso: tiopental intra-peritoneal; II- Control inhalatorio: isoflurano a 1,2% en O2 100%; III- Óxido Nitroso: N2O 66% en oxígeno e isoflurano a 0,6%. Los termogramas provenientes de la descompresión abdominal fueron obtenidos, por medio de un radiómetro AGEMA 550 filmados a 7 cuadros por segundo. RESULTADOS: El N2O se demostró visible al infrarrojo. En el momento de la descompresión abdominal, no hubo en los grupos I y II termogramas con rastros de gases visibles al infrarrojo. Hubo, todavía, rastros de gases visibles al infrarrojo en el grupo III. CONCLUSIONES: Se concluye que el óxido nitroso inhalatorio a 66% se difundió para la cavidad peritoneal de ratones sometidos a pneumoperitoneo de 20 mmHg con aire ambiente, sin aumento de la presión intra-abdominal.BACKGROUND AND OBJECTIVES: Nitrous oxide (N2O, for its tri-atomic asymmetric structure, has high energy emission and absorption characteristics within the infrared spectrum, with maximum absorption at 4.5 µm, what makes it visible at short infrared, when contrasted with a heat emission source (hot support.

  6. [Intestinal occlusion and abdominal compartment syndrome (ACS)].

    Stagnitti, Franco

    2009-01-01

    Intestinal occlusion is defined as an independent predictive factor of intra-abdominal hypertension (IAH) which represents an independent predictor of mortality. Baggot in 1951 classified patients operated with intestinal occlusion as being at risk for IAH ("abdominal blow-out"), recommending them for open abdomen surgery proposed by Ogilvie. Abdominal surgery provokes IAH in 44.7% of cases with mortality which, in emergency, triples with respect to elective surgery (21.9% vs 6.8%). In particular, IAH is present in 61.2% of ileus and bowel distension and is responsible for 52% of mortality (54.8% in cases with intra-abdominal infection). These patients present with an increasing intra-abdominal pressure (IAP) which, over 20-25 mmHg, triggers an Abdominal Compartment Syndrome (ACS) with altered functions in some organs arriving at Multiple Organ Dysfunction Syndrome (MODS). The intestine normally covers 58% of abdominal volume but when there is ileus distension, intestinal pneumatosis develops (third space) which can occupy up to 90% of the entire cavity. At this moment, Gastro Intestinal Failure (GIF) can appear, which is a specific independent risk factor of mortality, motor of "Organ Failure". The pathophysiological evolution has many factors in 45% of cases: intestinal pneumatosis is associated with mucosal and serous edema, capillary leakage with an increase in extra-cellular volume and peritoneal fluid collections (fourth space). The successive loss of the mucous barrier permits a bacterial translocation which includes bacteria, toxins, pro-inflammatory factors and oxygen free radicals facilitating the passage from an intra-abdominal to inter-systemic vicious cyrcle. IAH provokes the raising of the diaphragm, and vascular and visceral compressions which induce hypertension in the various spaces with compartmental characteristics. These trigger hypertension in the renal, hepatic, pelvic, thoracic, cardiac, intracranial, orbital and lower extremity areas, giving

  7. Abdominal MRI in childhood

    MRI provides diagnostic information in multiple abdominal diseases in childhood. Additional information to sonographic findings can be achieved in the diagnosis of abdominal malformation as well as in several inflammatory processes. In childhood cancer imaging MRI is essential at the beginning as well as during therapy to assess response to therapy. Because of radiation protection MRI has to replace CT in abdominal imaging in children. Some technical details have to be considered when children are examined. (orig.)

    Background: Abdominal desmoid tumor is one of the forms of deep (musculoaponeurotic) fibromatosis. It occurs more often as a desmoid tumor in the abdominal wall, less often in various intra-abdominal locations. In this work, we performed retrospective study concerning diagnostic problems of this disease with the use of imaging techniques. Method: Four patients (three females and one male) were examined by postcontrast CT (computed tomography) and one of them also by MR (magnetic resonance). All findings were correlated with the operational findings and histologic examination. Results: The findings were typical only in the case with the lesion located in the abdominal wall, three described cases of the intra-abdominal desmoid provided a broad range of differentially diagnostic possibilities (metastases, GIT tumors, lymphomas, etc.). In particular, the findings in infiltrative processes in intra-abdominal location and retroperitoneal involvement were less typical. Ultimately, the histological findings were decisive. Conclusion: The possibility of the occurrence of intra-abdominal desmoid tumor must be considered particularly in younger individuals with rapidly growing tumorous process, which does not immediately arise from the surrounding organs (digestive tract, internal genitalia, etc.), and is located in the abdominal wall or in the abdominal cavity.

Nowadays laparoscopy has become an accepted practice in hemodynamically stable patient without signs of peritonitis. We report a case of a lower anterior abdominal gunshot patient treated laparoscopically. A 32-year-old male presented to the Emergency Department with complaint of gunshot penetrating injury at left lower anterior abdominal wall. The patient had no symptoms or obvious bleeding and was vitally stable. On examination we identified 1 cm diameter entry wound at the left lower abdominal wall. The imaging studies showed the bullet in the peritoneal cavity but no injured intraperitoneal and retroperitoneal viscera. We decided to remove the bullet laparoscopically. Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically.

    Full Text Available Neonatal abdominal masses have broad spectrum of pathology, ranging from small lesions found incidentally to large masses occupying the entire of peritoneal cavity. These tumors are benign to malignant, and from unilocular cysts to complex solid lesions. Many of these lesions identified and will treat before delivery. Others are discovered during routine examination. These lesions may be life threatening, or cause persistent morbidity. Some of these have no sequel."nDiagnosis began with history. Characteristic of the mass which must be note include location, size, shape, texture, mobility and tenderness. Other findings should be in mind to find out nature of mass, for example hypoplasia of chest wall with oligohydramnios due to GU tract obstruction (potter sequwnce, a bulging hymen due to hydrometrocolpus, skin metastasis due to neuroblastoma. Radiography is the next step that shows organomegaly and calcification. Next step is US which is an excellent screening tool. CT and MRI are occasionally indicated."nThe purpose of this presentation is to review the diagnosis of abdominal masses in neonates.

    1998-07-01

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy. PMID:9737070

    The pulse of a particle accelerator. 128 of these radio frequency cavities were positioned around CERN's 27-kilometre LEP ring to accelerate electrons and positrons. The acceleration was produced by microwave electric oscillations at 352 MHz. The electrons and positrons were grouped into bunches, like beads on a string, and the copper sphere at the top stored the microwave energy between the passage of individual bunches. This made for valuable energy savings as it reduced the heat generated in the cavity.

  19. Abdominal tuberculosis: Imaging features

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis

  1. CT diagnosis of concealed rupture of intestine following abdominal trauma

    Objective: To investigate CT findings of concealed rupture of intestine following abdominal trauma. Methods: CT findings of 11 cases with concealed rupture of intestine following abdominal trauma proved by surgery were identified retrospectively. Results: The main special signs included: (1) Free air in 4 cases, mainly around injured small bowel or under the diaphragm, or in the retroperitoneal space or and in the lump. (2) High density hematoma between the intestines or in the bowel wall (4 cases). (3) Bowel wall injury sign, demonstrated as low density of the injured intestinal wall, attenuated locally but relatively enhanced in neighbor wall on enhanced CT. (4) Lump around the injured bowel wall with obvious ring-shaped enhancement (4 cases). Other signs included: (1) Free fluid in the abdominal cavity or between the intestines with blurred borders. (2) Bowel obstruction. Conclusion: CT is valuable in diagnosing concealed rupture of intestine following abdominal trauma. (authors)

  2. Aggressive malignant abdominal mesothelioma: Clinical report

    A 32-year-old Filipino female, working as an x-ray technician, presented to the Emergency Room (ER) with acute abdominal pain for one day. The pain was mainly on the left side and left hypochondrium. She had recurring abdominal pain before but not significant to worry her. She also complained of abdominal distension, which she noticed one week ago. Abdominal examination revealed fullness in the left hypochondrium with marked tenderness but negative rebound. Abdominal ultrasound (US) showed a huge mass mainly in the left hypochondrium. The origin of the mass cannot be identified by US. A computerized tomography scan showed a mass in the left side of the abdomen crossing the midline with a necrotic centre. The hospital course of the patient runs smoothly, and she was discharged after 7-days and referred to an Oncology Center. Abdominal mesothelioma is a neoplasm arising from the mesothelial surface lining the abdominal cavity. It is less frequent than that of the pleura. It is a rapidly growing and fatal malignancy with a median survival of less than 1-year. The relation between pleural malignant mesothelioma and asbestos is well recognized since it was described in 19602 but implication of asbestos exposure in the etiology of the peritoneal type is less obvious. This patient history is giving no obvious exposure to asbestos but as she is working in the Radiology Department as an x-ray technician she is well exposed to x-ray, but the effect of radioactivity on induction of mesothelioma is still disputed.4 There are several reports linking malignant mesothelioma to radioactivity due to radiation therapy.The fibrous mesothelioma (sarcomatous), as in this case, which is difficult to diagnose microscopically, looks like a fibroma, unless helped by tissue culture. The treatment options of malignant mesothelioma include surgery, intraperitoneal chemotherapy and whole abdominal radiation or multimodality therapy, which were suggested that might prolong the survival in

  3. accelerating cavity

    On the inside of the cavitytThere is a layer of niobium. Operating at 4.2 degrees above absolute zero, the niobium is superconducting and carries an accelerating field of 6 million volts per metre with negligible losses. Each cavity has a surface of 6 m2. The niobium layer is only 1.2 microns thick, ten times thinner than a hair. Such a large area had never been coated to such a high accuracy. A speck of dust could ruin the performance of the whole cavity so the work had to be done in an extremely clean environment.

  4. Childhood abdominal cystic lymphangioma

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two. Conclusions: US

  6. Abdominal Dual Energy Imaging

    Sommer, F. Graham; Brody, William R.; Cassel, Douglas M.; Macovski, Albert

    1981-11-01

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

  7. Abdominal Vascular Catastrophes.

    Singh, Manpreet; Koyfman, Alex; Martinez, Joseph P

    2016-05-01

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

    2006-01-01

    Full Text Available Ectopic pregnancy (EP is a potentially life-threatening condition in which the embryo implants outside the uterine endometrial cavity. Abdominal pregnancy is an atypical site wherein the product of conception lies totally outside the reproductive tract. Primary abdominal pregnancy is a very rare condition with a high mortality rate. Diagnosis is often late or misdiagnosed. The aim of introducing this case report is to present a new case of early primary abdominal pregnancy. Despite regular menstrual bleeding and contraception with IUD (intrauterine device, this pregnancy occurred in a 24-year old woman. Emergency laparotomy was performed because of abdominal pain, unstable condition and positive urine pregnancy test. It revealed more than 1500 ml of blood in the abdominal cavity. The uterus, both fallopian tubes and ovaries were completely intact. A 3X4 cm mass lateral to the left utersacral ligament was observed and resected. Since IUD strings could not be identified, endometrial currettage was performed and then the IUD was removed. Histological report of the mass and tissue of uterine cavity was placental villi and secretory endometrium, respectively, which according to Studdifords criteria is a new case of early primary abdominal pregnancy. To reduce maternal mortality and morbidity, early recognition of ectopic pregnancy is critical. According to review of the literature and the case report, a high index of suspicion is vital for the early diagnosis of ectopic pregnancy because the signs and symptoms of EP overlap with many surgical and gynecologic conditions. With early diagnosis of EP, we can suggest many therapeutic options and also retain fertility (if desired by patient, while minimizing disease and treatment-related morbidity.

  11. Adult abdominal hernias.

    Murphy, Kevin P

    2014-06-01

    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

  14. PET/CT Interpretation: Abdominal Anatomy

    Detail knowledge of abdominal anatomy is essential for accurate interpretation of oncologic PET/CT. The objective of this lecture is to provide the core knowledge and guidance about, peritoneal cavity, vessels, nodal, internal organ, especially liver segmental anatomy, and retroperitoneal spaces to nuclear medicine physicians in their interpretation of oncologic PET/CT. Peritoneal Cavity: The peritoneal spaces are easiest to recognize when there is ascites. The right subphrenic space communicates with anterior and posterior subhepatic (Morrison's) space. The left subphrenic space freely communicate with the left subhepatic space. The right and left subphrenic spaces are separated by falciform ligament and do not communicate directly. The lesser sac is the isolated peritoneal compartment between the stomach and pancreas. It communicates with the rest of the peritoneal cavity (greater sac) through the Foramen of Winslow. The right subphrenic and subhepatic spaces communicate freely with the pelvic peritoneal cavity thru the right paracolic gutter. The phrenicocolic ligament prevents free communication between the left subphrenic / subhepatic space and left paracolic gutter. Free fluid and peritoneal metastases commonly settles in pelvis as the most dependent portion of the peritoneal cavity. The small mesentery suspends the jejunum and ileum and extends obliquely from the left upper quadrant to right lower quadrant. Disease originating above the ligament is directed towards the right lower quadrant and below the ligament can spread to pelvis. The greater omentum hangs from the greater curvature of the stomach and descends in front of the abdominal viscera and serves as a fertile ground for peritoneal metastases. Vessels: The abdominal aorta descends anterior to the left side of the spine to its bifurcation at the level of the iliac crest. The normal aorta does not exceed 3 cm diameter and tapers progressively as it descends distally. The common iliac arteries

  15. [Intra-abdominal infection and new quinolones].

    Gnocchi, C A

    1999-01-01

    Intra-abdominal infection is defined as the presence of an infectious process within the peritoneal cavity. It may be local or have a systemic consequence generating multiple organic disfunction. Most of the studies report a mortality of 30% in severe intra-abdominal infection. Secondary peritonitis is caused by the loss of integrity of the gastrointestinal apparatus, which contaminates with pathogens the peritoneal cavity. Invariably they are polymicrobial infections, mostly due to facultative anaerobic and anaerobic Gram negative bacilli. Prognosis of peritonitis depends on the struggle between two forces: local and systemic immunity of the host and the volume, nature and length of the contamination. Microorganisms and their products estimulate cellular defenses in the host and activate numerous inflammatory mediators responsible for sepsis. Antibiotic treatment of secondary peritonitis must act mainly against Escherichia coli and Bacteroides fragilis. The adequate and early empirical administration of antibiotics against these bacteria is well established. It is necessary to consider if the infection is localized or generalized and if it is accompanied or not by organic disfunction. It also has to be taken into account if peritonitis is community or hospital-acquired when choosing the antibiotic scheme. In community-acquired peritonitis with low to moderate infections a combination of metronidazole-ceftriaxone, metronidazole-gentamycin or a monodrug like ampicillin-sulbactam may be used. In severe hospital-acquired peritonitis imipenem or the combination piperacillin-tazobactam are effective. New quinolones such as trovafloxacin or clinafloxacin, with excellent activity against aerobes and anaerobes producing intra-abdominal infections, may be effective. Future clinical trials are needed to determine their utility. Tertiary peritonitis represent a systemic inflammatory response with multiorganic failure due to the uncontrolled activation of the inflammatory

    The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries. (orig.)

    2005-01-01

    Objective: To explore the characteristics of closed abdominal injury in pregnancy women and its treatment.Methods: The clinical data of 37 pregnancy patients with closed abdominal injury treated in our hospital from June 1993 to June 2003 were collected and analyzed.Results: All the 37 patients were treated with operation. Among them 2 early pregnancy patients with intestinal rupture and 1 patient with retroperitoneal hematoma were treated under laparoscope; in other 34 pregnancy patients laparotomy was performed. Of the 34 patients 8 used cesarean section because premature separation of placenta and enlarged womb interrupted the management of intra-abdominal organ injury. In the 37 patients 33 (89.1%) were cured, 4 (10.8%) die, postoperative complication rate was 16.2% (6/37). Two patients (5.4%) suffered from abdominal cavity infection, 3 (8.1%) from pulmonary infection, and 1 (2.7%) had multi-organ failure.Conclusions: For pregnancy patients with closed abdominal injury, besides obsteric diseases intra-abdominal injury should be given much attention. Accurate diagnosis and timely treatment can gain the time to save the life of both mother and fetus.

    1985-12-15

    Authors analysed CT findings of 8 patients with tuberculous lymphadenitis and one case of tuberculous abscess diagnosed surgically or clinically. The results were as follows; 1. Soft tissue density masses were noted in 8 patients in paraaortic, mesenteric, peripancreatic, celiac, portahepatis, and esophagogastric junction areas in order of frequency, and these correspond to lymph node groups of the same name. On contrast enhanced CT, rim enhancement with multilocular low densities indicating caseous necrosis were not noted in 3 patients, ill defined low densities were seen in 3 patients, and no definite changes were noted in 2 patients. 2. Two or more lymph node groups were involved in 6 patients, and one lymph node group was involved in two patients. 3. A huge cystic mass with relatively irregular rim enhancement and small amount of solid component occupied nearly entire upper abdomen in 1 patient and this was confirmed as tuberculous abscess in peritoneum. 4. In 2 cases, bowel wall thickening was suggested in cecum, ascending colon, and terminal ileum.

  1. Component separation in abdominal trauma.

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

  3. CT of abdominal trauma

    Soon after it became available for clinical use, cranial CT became the method of choice for evaluating head trauma. Only relatively recently have newer generation full-body scanners been installed at major trauma centers, but experience is rapidly being gained in the utilization of CT for abdominal trauma. CT has proved highly accurate in diagnosing a wide variety of injuries to both intra- and retroperitoneal organs in pediatric and adult patient populations. The impact has been evident not only in decreasing utilization of other diagnostic tests, such as angiography, but also in practical management decisions, such as whether to perform exploratory laparotomy. This chapter details the authors' approach to evaluation of abdominal trauma by CT

  4. The blunt abdominal trauma

    Up to 1970 the number of patients suffering from blunt abdominal trauma showed a substantial increase. In more than 50% of all cases there are additional injuries. The most important factor influencing the prognosis of these patients is the early and correct indication for operation and the avoidance of unnecessary laparotomies. As a primary aim in diagnosis one should consider the recognition of an intraperitoneal bleeding without risk for the patient. Peritoneal lavage as an invasive method with low complication rates has proved good. First reports also show good results using the sonography of the abdomen. The recognition of the injured organ allows a carefully directed operation. Concerning the prognosis it is of minor importance. The diagnosis in patients with blunt abdominal trauma at the university clinic of Freiburg consists of: sonography, followed in positive cases by laparotomy or angiography and laparotomy. In cases with questionable results a lavage is done. (orig.)

  5. The abdominal circulatory pump.

    Andrea Aliverti

    Full Text Available Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume does not so that the blood volume shifted between trunk and extremities (Vbs is the difference between changes in trunk and body volume. This is so because both trunk and body volume change identically with breathing and gas expansion or compression. During tidal breathing Vbs was 50-75 ml with an ejection fraction of 4-6% and an output of 750-1500 ml/min. Step increases in abdominal pressure resulted in rapid emptying presumably from the liver with a time constant of 0.61+/-0.1SE sec. followed by slower flow from non-hepatic viscera. The filling time constant was 0.57+/-0.09SE sec. Splanchnic emptying shifted up to 650 ml blood. With emptying, the increased hepatic vein flow increases the blood pressure at its entry into the inferior vena cava (IVC and abolishes the pressure gradient producing flow between the femoral vein and the IVC inducing blood pooling in the legs. The findings are important for exercise because the larger the Vbs the greater the perfusion of locomotor muscles. During asystolic cardiac arrest we calculate that appropriate timing of abdominal compression could produce an output of 6 L/min. so that the abdominal circulatory pump might act as an auxiliary heart.

    2013-01-01

    Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

  8. Abdominal aspergillosis: CT findings

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

  10. Inhibiting Effect of Electroacupuncture at Zusanli on Early Inflammatory Factor Levels Formed by Postoperative Abdominal Adhesions

    Lijian Zhang

    2014-01-01

    Full Text Available We observed the inhibitive effect of electroacupuncture (EA at Zusanli on inflammatory mediators of postoperative intra-abdominal adhesions to find out the relationship between EA and the cholinergic anti-inflammatory pathway. Sixty-four rats were divided into 8 groups (A–H, each = 8: A = sham control; B = abdominal adhesions model; C = abdominal adhesions plus EA; D = sham acupoint control; E = abdominal adhesions plus vagotomy; F = abdominal adhesions plus EA after vagotomy; G = abdominal adhesions plus α-bungarotoxin (BGT; and H = abdominal adhesions plus EA after α-BGT. α-BGT (1 μg/kg was injected into the abdominal cavity after surgery, and the bilateral celiac vagotomy was done during the surgery. On the third day the levels of inflammatory mediators (TNF-α, nitric oxide (NO, and nitric oxide synthase (NOS in tissues were evaluated. The abdominal adhesion groups developed obvious edema. Compared with sham control, the abdominal adhesion resulted in a significant elevation of inflammatory mediators. EA lowered the elevated levels of inflammatory mediators significantly; EA plus α-BGT and vagotomy showed less anti-inflammatory effects. The activation of the cholinergic anti-inflammatory pathway might be one of the mechanisms of EA at Zusanli acupoints to exert the anti-inflammatory effects.

  11. Cavity magnomechanics

    2016-05-01

    Recently, cavity magnonics has attracted much attention for potential applications of coherent information transduction and hybrid quantum devices. The magnon is a collective spin wave excitation in ferromagnetic material. It is magnetically tunability, with long coherence time and non-reciprocical interaction with electro-magnetic fields. We report the coherent coupling between magnon, microwave photon and phonon. First, we demonstrate strong coupling and ultrastrong coupling between the magnon in YIG sphere and microwave photon in three-dimensional cavity. Then, based on the hybridized magnon-photon modes, we observe the triply resonant magnon-mcirowave photon-phonon coupling, where the ultrahigh-Q mechanical vibration of YIG sphere is dispersively coupled with the magnon via magnetostrictive interaction. We observe interesting phenomena, including electromagnetically induced transparency/absorption and parametric amplification. In particular, benefit from the large tunability of the magnon, we demonstrate a tunable microwave amplifier with gain as high as 30 dB. The single crystal YIG also has excellent optical properties, and thus provide a unique platform bridging MHz, GHz and THz information carriers. Finally, we present the latest progress towards coherent magnon to optical photon conversion.

    Full Text Available We report and discuss a case of primary hydatidosis of the pelvic cavity in a woman who presented with severe weight loss and abdominal pain. This unusual presentation was initially considered as a tumor process until surgical exploration and microscopic studies confirmed the diagnosis. The gynecologists should be aware of possibility of primary hydatid cyst of the pelvic cavity and should be considered in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

  14. [Differential diagnosis of abdominal pain].

    Frei, Pascal

    2015-09-01

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain. PMID:26331201

  16. Hypnosis for functional abdominal pain.

    Gottsegen, David

    2011-07-01

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

    2009-04-01

    Full Text Available Abstract Hydatid disease, caused by Echinococcus granulosus, is a common parasitic infection of the liver. Disseminated intra-abdominal hydatid disease may occur following rupture of the hydatid cyst into the peritoneal cavity, producing secondary echinococcosis. Rarely cyst may develop de-novo in the peritoneal cavity without involvement of any other intra-abdominal organs. We present a unique case of 56-year-old woman with a primary intraabdominal hydatid cyst in the right iliac fossa masquerading as appendicular lump.

  19. Practical pediatric abdominal CT

    This course is designed to help the radiologist in a hospital setting successfully approach abdominal CT in the infant and child. Emphasis is placed on techniques necessary for a high-quality examination of the upper abdomen, as applied to common pediatric problems such as trauma, tumor, and infection. Material is presented on technical considerations, including patient sedation, preparation, and potential pitfalls and helpful hints for imaging. An emphasis is placed on dynamic scanning with table incrementation. The section on trauma focuses on an approach to imaging the abdomen in the injured child, typical injuries, patterns of injury in the upper abdomen, and why CT is the best imaging modality for blunt upper abdominal trauma. The discussion of tumor imaging reviews the appearance of typical childhood neoplasia including Wilms tumor, neuroblastoma, non-Hodgkin and Burkitt lymphoma, and disseminated solid tumors such as rhabdomyosarcoma. The authors emphasize what to look for and where, both on initial and on later (for recurrences) examinations. The discussion of infection addresses detection of abscesses and occult infections in children, as well as imaging of abscesses prior to intervention

  20. Management of stab wounds to the anterior abdominal wall

    João Baptista Rezende-Neto

    2014-01-01

    Full Text Available The meeting of the Publication "Evidence Based Telemedicine - Trauma and Emergency Surgery" (TBE-CiTE, through literature review, selected three recent articles on the treatment of victims stab wounds to the abdominal wall. The first study looked at the role of computed tomography (CT in the treatment of patients with stab wounds to the abdominal wall. The second examined the use of laparoscopy over serial physical examinations to evaluate patients in need of laparotomy. The third did a review of surgical exploration of the abdominal wound, use of diagnostic peritoneal lavage and CT for the early identification of significant lesions and the best time for intervention. There was consensus to laparotomy in the presence of hemodynamic instability or signs of peritonitis, or evisceration. The wound should be explored under local anesthesia and if there is no injury to the aponeurosis the patient can be discharged. In the presence of penetration into the abdominal cavity, serial abdominal examinations are safe without CT. Laparoscopy is well indicated when there is doubt about any intracavitary lesion, in centers experienced in this method.

  1. [BIOLOGICAL IMPLANTS IN ABDOMINAL WALL HERNIA REPAIR (REVIEW)].

    Abatov, N; Badyrov, R; Abatova, A; Assamidanov, E; Kaukenov, B

    2016-02-01

    The use of synthetic meshes as a material for abdominal wall hernia repair does not always ensure a recurrence-free treatment outcome and full recovery of the abdominal wall functional activity. There are well-known disadvantages such as poor resistance to infection, the infiltrate formation in the place of implantation, expressed adhesive process in cases of introperitoneal fixation, to create certain restrictions on the using of these implants for abdominal wall reconstruction. The search for alternative materials that could minimize the risk of complications, has led to the study of biological grafts. It is known that various methods for the manufacturing biological implants determine endogenous properties for each material separately, and may be cause a variety of biological responses in vivo after implantation. The question has not been resolved, what the fresh raw material is better to use for derive biological implants. In this review we investigated the interaction of different types of biological implants between the abdominal wall and the organs of abdominal cavity of the recipient, their ability to resist infection and the development of relapses, as a leading indicator of the effectiveness of hernioplasty.

  2. Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

    Marincek, B. [Institute of Diagnostic Radiology, University Hospital Zurich, Raemistrasse 100, 8091 Zurich (Switzerland)

    2002-09-01

    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

    2014-01-01

    A relatively new surgical technique allows for sutureless closure of a gastroschisis defect. Immediately after birth, a long umbilical cord stump is temporarily inverted into the abdominal cavity and later retracted and used to close the abdominal wall defect. Knowledge of this entity is important since the inverted umbilical cord simulates an intra-abdominal mass on cross-sectional imaging. While this procedure is well described in the surgical literature, the imaging features of inverted umbilical cord have yet to be reported. The case presented here highlights the sonographic imaging findings of the umbilical cord during the intestinal decompression phase of sutureless repair of gastroschisis. PMID:23907187

  4. The value of ultrasonography and computed tomography in the blunt abdominal trauma: a prospective study

    From August to December 1988, eleven patients with abdominal trauma, hemodynamically stable, were studied at Souza Aguiar Municipal Hospital in Rio de Janeiro, Brazil. After physical evaluation and initial resuscitation, these patients underwent abdominal paracentesis, basic roentgenographic examination and computed tomography. Either a conservative treatment or an exploratory laparotomy was carried out regarding the results of the examination. The use of ultrasound and computed tomography examination in patients with doubtful diagnosis proved to be effective and enable us to identify not only intra-abdominal and retroperitoneal lesions but also the presence of liquid collections in the peritoneal cavity.

Most of the studied patients were in the age range from 31 to 40 years with 21 patients (51, 2 % the open abdominal trauma with 26 patients prevailed (63, 4 %. The masculine sex prevailed with 38 patients (92,7 % and as much the open trauma as the closed one were more frequent in this sex with 25 patients (96,2 % and 13 patients (86,7 % respectively. They didn't show visceral damage during the laparoscopy 93, 3 % of the patients with closed abdominal trauma by what the surgical treatment was avoided, the same as in the patients with open abdominal trauma which had a non penetrating damage in abdominal cavity (80, 8 %. Conclusion: laparoscopic diagnosis is a useful test in patients with abdominal trauma and it avoids a considerable number of unnecessary conventional surgical treatment.

  6. Cavity magnomechanics

    Zhang, Xufeng; Zou, Changling; Jiang, Liang; Tang, Hong X.

    Mechanical oscillators have been recently widely utilized to couple with optical and microwave photons in a variety of hybrid quantum systems, but they all lack the tunability. The magnetostrictive force provides an alternative mechanism to allow phonon to couple with a different type of information carrier-magnon, the collective excitation of magnetization whose frequency can be tuned by a bias magnetic field. Here, we demonstrate an intriguing hybrid system that consists of a magnonic, a mechanical, and a microwave resonator. The magnon-phonon interaction results in hallmark coherent phenomena such as magnomechanically induced transparency/absorption and magnomechanical parametric amplification. The magnetic field dependence of magnon provides our system with unprecedented tunability. Moreover, the great flexibility of our system allows us to achieve triple resonance among magnon, phonon and photon, which drastically enhances the magnomechanical interaction. Our work demonstrates the fundamental principle of cavity magnetomechanics, opening up great opportunities in various applications, such as tunable microwave filter and amplifier, long-lifetime quantum memories, microwave-to-optics conversion.

  7. Abdominal lymphadenopathy detection using random forest

    Cherry, Kevin M.; Wang, Shijun; Turkbey, Evrim B.; Summers, Ronald M.

    2014-03-01

    We propose a new method for detecting abdominal lymphadenopathy by utilizing a random forest statistical classifier to create voxel-level lymph node predictions, i.e. initial detection of enlarged lymph nodes. The framework permits the combination of multiple statistical lymph node descriptors and appropriate feature selection in order to improve lesion detection beyond traditional enhancement filters. We show that Hessian blobness measurements alone are inadequate for detecting lymph nodes in the abdominal cavity. Of the features tested here, intensity proved to be the most important predictor for lymph node classification. For initial detection, candidate lesions were extracted from the 3D prediction map generated by random forest. Statistical features describing intensity distribution, shape, and texture were calculated from each enlarged lymph node candidate. In the last step, a support vector machine (SVM) was trained and tested based on the calculated features from candidates and labels determined by two experienced radiologists. The computer-aided detection (CAD) system was tested on a dataset containing 30 patients with 119 enlarged lymph nodes. Our method achieved an AUC of 0.762+/-0.022 and a sensitivity of 79.8% with 15 false positives suggesting it can aid radiologists in finding enlarged lymph nodes.

  8. Differential diagnosis of pelvic cavities containing gas and fluids

    Since untreated intra-abdominal abscesses are associated with a high mortality rate, early diagnosis is important. In abscesses involving gas formation, plain radiographs of the abdomen in various projections are sufficient for diagnosis.

  11. Penetrating abdominal trauma.

    Henneman, P L

    1989-08-01

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

  12. Economics of abdominal wall reconstruction.

    Bower, Curtis; Roth, J Scott

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

  13. Automated recognition of body cavities in torso X-ray CT images

    Recently, it has become even more important to understand the normal anatomical structures of the human body in the field of radiological image anatomy. The recognition of body cavities is useful when organ extraction is performed. However, it is difficult to perform organ extraction and to obtain a clear understanding of anatomical structures based on CT values. For example, the distributions of the CT numbers of muscle and organs overlap each other. Therefore, the recognition of the body cavity domain can reduce the range of internal organ extraction and simplify organ segmentation. The purpose of the present study was to develop an automated method for recognizing the body cavities in torso X-ray CT images. Our body cavity recognition method is based on skeletal positions and is performed by extracting the borders of the thoracic cavity, abdominal cavity, and pelvic cavity. This method detects the initial and final points of such borders and searches for the shortest path on the surfaces of the skeletal structures. It then generates the boundary surfaces of the thoracic, abdominal, and pelvic cavities by drawing straight lines between the shortest paths and the centers of the paths. The body cavities located between the superior thoracic aperture and the diaphragm, the diaphragm and the pelvic inlet, and the pelvic inlet and the pelvic outlet are regarded as the thoracic cavity, the abdominal cavity, and the pelvic cavity, respectively. The method was applied to 20 cases in which torso X-ray CT images were obtained. The results showed that the body cavities were extracted correctly in most cases: the thoracic cavity in 17 cases, the abdominal cavity in 19 cases, and the pelvic cavity in 18 cases. We confirmed that our proposed method is effective for recognizing these body cavities. As one of the applications of our study, segmentation of muscle, fat, and the rectum in CT images was performed using the information obtained for body cavity structures. The results

  14. Percutaneous Transhepatic Drainage of Inaccessible Abdominal Abscesses Following Abdominal Surgery Under Real-Time CT-Fluoroscopic Guidance

    This study evaluated the safety, feasibility, and clinical utility of transhepatic drainage of inaccessible abdominal abscesses retrospectively under real-time computed tomographic (CT) guidance. For abdominal abscesses, 12 consecutive patients received percutaneous transhepatic drainage. Abscesses were considered inaccessible using the usual access route because they were surrounded by the liver and other organs. The maximum diameters of abscesses were 4.6-9.5 cm (mean, 6.7 ± 1.4 cm). An 8-Fr catheter was advanced into the abscess cavity through the liver parenchyma using real-time CT fluoroscopic guidance. Safety, feasibility, procedure time, and clinical utility were evaluated. Drainage catheters were placed with no complications in abscess cavities through the liver parenchyma in all patients. The mean procedure time was 18.8 ± 9.2 min (range, 12-41 min). All abscesses were drained. They shrank immediately after catheter placement. In conclusions, this transhepatic approach under real-time CT fluoroscopic guidance is a safe, feasible, and useful technique for use of drainage of inaccessible abdominal abscesses.

  18. Updates on abdominal desmoid tumors

    2007-01-01

    Desmoid tumor is a monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. This connective tissue hyperplasia infiltrates locally, recurs frequentiy after resection but does not metastasize. Abdominal desmoid occurs sporadically, in association with some familial syndromes and often represents a clinical dilemma for surgeons. The enigmatic biology and anatomical location of abdominal desmoids make treatment recommendations difficult. This distinct pathological entity is reviewed with a specific focus on aetiology and management.

    2009-01-01

    Full Text Available Abstract Introduction Abdominal pregnancy is a rare event, but one that represents a grave risk to the health of the pregnant woman. An abdominal pregnancy is defined as an ectopic pregnancy that implants in the peritoneal cavity. Early abdominal pregnancy is self-limited by hemorrhage from trophoblastic invasion with complete abortion of the gestational sac that leaves a discrete crater. Advanced abdominal pregnancy is a rare event, with high fetal and maternal morbidity and mortality. Case presentation This is a case report of a 22-year-old primigravida with an abdominal pregnancy from a ruptured rudimentary horn. She was diagnosed as a case of term pregnancy with placenta previa with a transverse fetal lie and cervical fibroid and was prepared for an elective cesarean section. Intra-operatively, a live term female baby was extracted from the peritoneal cavity and it turned out to be an abdominal pregnancy from a ruptured rudimentary horn of a unicornuate uterus, which is a very rare condition. Mother and baby were in good condition after such a catastrophic event. Conclusion This case illustrates a rare obstetric condition which can be a severe catastrophic condition leading to maternal mortality and morbidity. It is imperative for every obstetrician to have in mind the possibility of abdominal pregnancy, although rare, especially in pregnant patients with persistent abdominal pain and painful fetal movements.

  3. Computer tomography following blunt abdominal trauma

    The computer tomographic appearances of lesions of parenchymatous organs following blunt abdominal trauma are described in 13 patients (five liver, four renal, two splenic and two pancreatic injuries). The value of abdominal computer tomography is discussed in relation to the interval between injury and time of abdominal examination and compared with the diagnostic value of abdominal angiography.

  4. Automatic segmentation of abdominal vessels for improved pancreas localization

    Farag, Amal; Liu, Jiamin; Summers, Ronald M.

    2014-03-01

    Accurate automatic detection and segmentation of abdominal organs from CT images is important for quantitative and qualitative organ tissue analysis as well as computer-aided diagnosis. The large variability of organ locations, the spatial interaction between organs that appear similar in medical scans and orientation and size variations are among the major challenges making the task very difficult. The pancreas poses these challenges in addition to its flexibility which allows for the shape of the tissue to vastly change. Due to the close proximity of the pancreas to numerous surrounding organs within the abdominal cavity the organ shifts according to the conditions of the organs within the abdomen, as such the pancreas is constantly changing. Combining these challenges with typically found patient-to-patient variations and scanning conditions the pancreas becomes harder to localize. In this paper we focus on three abdominal vessels that almost always abut the pancreas tissue and as such useful landmarks to identify the relative location of the pancreas. The splenic and portal veins extend from the hila of the spleen and liver, respectively, travel through the abdominal cavity and join at a position close to the head of the pancreas known as the portal confluence. A third vein, the superior mesenteric vein, anastomoses with the other two veins at the portal confluence. An automatic segmentation framework for obtaining the splenic vein, portal confluence and superior mesenteric vein is proposed using 17 contrast enhanced computed-tomography datasets. The proposed method uses outputs from the multi-organ multi-atlas label fusion and Frangi vesselness filter to obtain automatic seed points for vessel tracking and generation of statistical models of the desired vessels. The approach shows ability to identify the vessels and improve localization of the pancreas within the abdomen.

    2008-06-01

    Full Text Available Endometriosis is described as the presence of functioning endometrial tissue (glands and stroma outside the uterine cavity. The most common location is within the pelvis. However, extra pelvic endometriosis is a fairly uncommon disorder and difficult to diagnose. It can sometimes occur in a surgical scar. Scar endometriosis is a rare condition and difficult to diagnose. It mostly follows obstetrical and gynecological surgeries. It presents as a painful, slowly growing mass in or near a surgical scar. We report two cases of abdominal wall endometriosis following hysterotomy and cesarean section. Consequently the pathogenesis, diagnosis and treatment are discussed.

  8. Detection of abdominal bleeding in blunt abdominal trauma

    Arterial hemorrhage is the most serious immediate complication of blunt abdominal trauma. This paper discusses the detection and localization of active hemorrhage in nonpenetrating injury, as a modification of the technique using technetium-99m sulfur colloid to localize the site of active bleeding in the gastrointestinal tract. Any imaging protocol for suspected hepatosplenic injury can be easily modified to search for active intra-abdominal hemorrhage. The timely detection of unsuspected bleeding improves patient management by allowing the surgeon to reorder his or her treatment priorities. The early detection of clinically unsuspected intra-abdominal, retroperitoneal, or pelvic hemorrhage will identify those patients who may need more definitive diagnostic procedures, interventional angiography for control of bleeding, or surgical intervention. The 500,000-count view of the abdomen and pelvis can be easily incorporated into any existing trauma protocol using technetium-99m sulfur colloid, is of proven value, and adds little additional time to the study

    2003-01-01

    AIM: To evaluate the clinical, radiological and microbiological properties of abdominal tuberculosis (TB) and to discuss methods needed to get the diagnosis.METHODS: Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital,Istanbul, Turkey were evaluated prospectively. Complete physical examination, medical and family history, blood count erythrocyte sedimentation rate, routine biochemical tests,Mantoux skin test, chest X-ray and abdominal ultrasonography (USG) were performed in all cases, whereas microbiological examination of ascites, upper gastrointestinal endoscopy, colonoscopy or barium enema, abdominal tomography, mediastinoscopy, laparoscopy or laparotomy were done when needed.RESULTS: The median age of patients (14 females, 17males) was 34.2 years (range 15-65 years). The most frequent symptoms were abdominal pain and weight loss.Eleven patients had active pulmonary TB. The most common abdominal USG findings were ascites and hepatomegaly. Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2 %). Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients. Colonoscopy performed in 20 patients showed ulcers in 9 (45 %), nodules in 2 (10 %)and, stricture, polypoid lesions, granulomatous findings in terminal ileum and rectal fistula each in one patient (5 %).Laparoscopy on 4 patients showed dilated bowel loops,thickening in the mesentery, multiple ulcers and tubercles on the peritoneum. Patients with abdominal TB were divided into three groups according to the type of involvement.Fifteen patients (48 %) had intestinal TB, L1 patients (35.2 %) had tuberculous peritonitis and 5 (16.8 %)tuberculous lymphadenitis. The diagnosis of abdominal TB was confirmed microbiologically in 5 (16 %) and histopathologically in 19 patients (60.8 %). The

    1993-03-01

    A 26-years-old Indian male was admitted to hospital with loss of weight and vague abdominal pain of several weeks duration. Ultrasonography and computed tomography showed several expansive lesions near the pancreatic head, probably representing enlarged lymph nodes. A few milliliters of yellowish pus were aspirated by ultrasound guided aspiration. Microscopic examination of the pus showed trophozoits, and mycobacterium tuberculosis subsequently grew from the pus culture. Abdominal tuberculosis is a rare condition, particularly in the pancreas and the peripancreatic region. The report stresses the importance of considering the possible coexistance of more than one infectious disease in patients from endemic areas. 21 refs., 2 figs.

  13. Non-traumatic abdominal emergencies: imaging and intervention in sepsis

    Cross-sectional imaging, in particular CT, has become the main method of detecting abdominal collections. Indium-labelled white-cell scintigraphy and gallium scintigraphy are reserved for patients in whom there is a high clinical suspicion of abdominal sepsis but CT has not revealed a source of sepsis. Scintigraphy is also used in patients with suspected vascular graft infections or suspected infected hip prostheses. Percutaneous abscess drainage (PAD) has revolutionised the treatment of abdominal abscesses over the past 20 years, with repeat laparotomy for postoperative abscesses becoming a rare event. Ultrasound or CT can be used to guide PAD. Choosing an access route that does not cross intervening organs is of crucial importance to the safe performance of PAD. The Trocar or Seldinger techniques can be used with equal success. The cavity should be aspirated until dry and irrigated with saline. Repeat imaging after drainage is helpful to detect any undrained locules. PAD endpoints include patient defervescence, reduction in white blood cell count and catheter drainage of less than 10 ml per day. Details regarding PAD in specific abdominal regions are discussed. Success rates for PAD are high (close to 90%) in most abdominal organs. Slightly lower success rates are seen with PAD of pancreatic abscesses and abscesses associated with fistulas (60-85% success rates). Complication rates lie between 0% and 10%. Complications can be minimised by ensuring that the patient has broad spectrum antibiotic coverage before drainage, by carefully planning the access route and by ensuring diligent post-procedure care by radiology staff.

  15. Beam cavity interaction

    Gamp, A

    2011-01-01

    We begin by giving a description of the rf generator-cavity-beam coupled system in terms of basic quantities. Taking beam loading and cavity detuning into account, expressions for the cavity impedance as seen by the generator and as seen by the beam are derived. Subsequently methods of beam-loading compensation by cavity detuning, rf feedback, and feed-forward are described. Examples of digital rf phase and amplitude control for the special case of superconducting cavities are also given. Finally, a dedicated phase loop for damping synchrotron oscillations is discussed.

  16. Abdominal radiation causes bacterial translocation

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa

  18. Contemporary imaging in abdominal emergencies

    Imaging is often a fundamental part in the evaluation of an injured or ill child. A variety of imaging modalities (radiography, angiography/fluoroscopy, sonography, CT, magnetic resonance imaging and scintigraphy) are among the options. CT is worth focused attention because of its usefulness in a variety of emergency department settings, its increasing use, and its potential radiation risks. CT plays an important role in the evaluation of traumatic and nontraumatic abdominal emergencies in children. Therefore, the goal of this paper is to review current imaging approaches and controversies in the evaluation of common acute abdominal emergencies. Through discussion of various modalities, especially CT in evaluation of abdominal pain and trauma, the relative advantages and disadvantages including radiation risk will be reviewed. (orig.)

Conclusion: CT is sensitive and precise in evaluating abdominal trauma, providing important information for treatment. (author)

  1. Cavity turnover and equilibrium cavity densities in a cottonwood bottomland

    Sedgwick, James A.; Knopf, Fritz L.

    1992-01-01

    A fundamental factor regulating the numbers of secondary cavity nesting (SCN) birds is the number of extant cavities available for nesting. The number of available cavities may be thought of as being in an approximate equilibrium maintained by a very rough balance between recruitment and loss of cavities. Based on estimates of cavity recruitment and loss, we ascertained equilibrium cavity densities in a mature plains cottonwood (Populus sargentii) bottomland along the South Platte River in northeastern Colorado. Annual cavity recruitment, derived from density estimates of primary cavity nesting (PCN) birds and cavity excavation rates, was estimated to be 71-86 new cavities excavated/100 ha. Of 180 active cavities of 11 species of cavity-nesting birds found in 1985 and 1986, 83 were no longer usable by 1990, giving an average instantaneous rate of cavity loss of r = -0.230. From these values of cavity recruitment and cavity loss, equilibrium cavity density along the South Platte is 238-289 cavities/100 ha. This range of equilibrium cavity density is only slightly above the minimum of 205 cavities/100 ha required by SCN's and suggests that cavity availability may be limiting SCN densities along the South Platte River. We submit that snag management alone does not adequately address SCN habitat needs, and that cavity management, expressed in terms of cavity turnover and cavity densities, may be more useful.

  2. Radiological evaluation of abdominal trauma

    Simple abdomen film has played an important role in decision of emergency operations in patients with the abdominal trauma. Nowadays, it still acts as a primary and inevitable processes in emergency condition. At the Department of Radiology, Hanil Hospital, 70 patients, who were laparotomied due to penetrating or nonpernetraing abdominal trauma, were observed and analyzed with simple abdomen film after comparison with the operative findings. The results are as follows: 1. Most frequent age distribution was 10 to 39 years and marked 70%. Male was in 90% incidence. 2. Penetrating injury largely involved the small bowel and abdominal wall. Non-penetrating injury usually involved the spleen, small bowel, liver, kidney, pancreas, duodenum. 3. Single organ injury occurred in higher incidence at the small bowel and abdominal wall. Multiple organ injury occurred in higher incidence at the spleen, liver, kidney and pancreas. 4. Organ distribution was 26% in spleen, 22% in small bowel, 14% in liver, 11% in abdominal wall. 7% in pancreas, 7% in kidney. 5% in duodenum, 4% in GB and CBD, 2% in diaphragm, 2% in colon, and 1% in stomach. 5. The specific roentgen findings and their frequency which useful in differential diagnosis at abdominal trauma, were as follows: a) flank fluid; Detectable possibility was 71% in liver laceration, 69% in spleen laceration and 57% in pancreas laceration. b) ipsilateral psoas shadow obliteration; Detectable possibility was 57% in liver laceration, 57% in kidney laceration and 46% in spleen laceration. c) free air; Detactable possibility was 60% in duodenal perforation, and 36% in peroration of upper part of small bowel. d) Reflex ileus; Detectable possibility was 64% in small bowel, 50% in liver laceration and 35% in spleen laceration. e) rib fracture; Detactable possibility was 36% in liver laceration and 23% in spleen laceration. f) pleural effusion; Detectable possibility was 29% in liver laceration and 27% in spleen laceration

    Eighty five children with recurrent abdominal pain(RAP) were studied. Organic cause was noticed in 70 cases and non-organic in 15 cases. Giardiasis was the commonest organic cause in 57 (67.0 percent), either alone or with other parasitic infestations. Other organic causes include gallstones (4.7 percent), urinary infections (4.7 percent), esophagitis/gastritis (3.5 percent) and abdominal tuberculosis (2.3 percent). Single parent, school phobia, sibling rivalry, RAP in other family members and nocturnal enuresis are significant factors associated with nonorganic causes PMID:12368527

    2007-01-01

    Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations. We present an interesting case of secondary implantation of a tubal ectopic pregnancy to highlight the appendix as a possible secondary implantation site after a tubal ectopic pregnancy.

  5. Plain abdominal film and abdominal ultrasound in intestine occlusion

    Plain film of the abdomen is widely used in the diagnostic evaluation of intestinal occlusion. Even though this technique can yield a panoramic and high-resolution view of gas-filled intestinal loops, several factors, such as type and duration of occlusion, neurovascular status of the intestine and general patient condition, may reduce the diagnostic specificy of the plain film relative to the organic or functional nature of the occlusion. From 1987 to 1989, fifty-four patients with intestinal occlusion were studied combining plain abdominal film with abdominal ultrasound (US). This was done in order to evaluate whether the additional information obtained from US could be of value in better determining the nature of the ileus. US evaluation was guided by the information already obtained from plain film which better demonstrates gas-filled loops. The results show that in all 27 cases of dynamic ileus (intestinal ischemia, acute appendicitis, acute cholecistis, acute pancreatitis or blunt abdominal trauma) US demonstrates: intestinal loops slightly increased in caliber, with liquid content, or loops containing rare hyperechoic particles, intestinal wall thickening and no peristalsis. In 27 cases of acute, chronic or complicated mechanical ileus (adhesions, internal hernia, intestinal neoplasm, peritoneal seedings) US shows: 1) in acute occlusion: hyperperistaltic intestinal loops containing inhomogeneous liquid; 2) in chronic occlusion: liquid content with a solid echigenic component; 3) in complicated occlusion: liquid stasis, frequent increase in wall thickness, moderate peritoneal effusion and inefficient peristalsis. In conclusion, based on the obtained data, the authors feel that the combination of plain abdominal film and abdominal US can be useful in the work-up of patient with intestinal occlusion. The information provided by US allows a better definition of the nature of the ileus

  6. Intra-abdominal fat. Part I. The images of the adipose tissue localized beyond organs.

    Smereczyński, Andrzej; Kołaczyk, Katarzyna; Bernatowicz, Elżbieta

    2015-09-01

    Unaltered fat is a permanent component of the abdominal cavity, even in slim individuals. Visceral adiposity is one of the important factors contributing to diabetes, cardiovascular diseases and certain neoplasms. Moreover, the adipose tissue is an important endocrine and immune organ of complex function both when normal and pathological. Its role in plastic surgery, reconstruction and transplantology is a separate issue. The adipose tissue has recently drawn the attention of research institutes owing to being a rich source of stem cells. This review, however, does not include these issues. The identification of fat is relatively easy using computed tomography and magnetic resonance imaging. It can be more difficult in an ultrasound examination for several reasons. The aim of this paper is to present various problems associated with US imaging of unaltered intra-abdominal fat located beyond organs. Based on the literature and experience, it has been demonstrated that the adipose tissue in the abdominal cavity has variable echogenicity, which primarily depends on the amount of extracellular fluid and the number of connective tissue septa, i.e. elements that potentiate the number of areas that reflect and scatter ultrasonic waves. The normal adipose tissue presents itself on a broad gray scale: from a hyperechoic area, through numerous structures of lower reflection intensity, to nearly anechoic regions mimicking the presence of pathological fluid collections. The features that facilitate proper identification of this tissue are: sharp margins, homogeneous structure, high compressibility under transducer pressure, no signs of infiltration of the surrounding structures and no signs of vascularization when examined with the color and power Doppler. The accumulation of fat tissue in the abdominal cavity can be generalized, regional or focal. The identification of the adipose tissue in the abdominal cavity using ultrasonography is not always easy. When in doubt, the

  7. Pulsatile blood flow in Abdominal Aortic Aneurysms

    Salsac, Anne-Virginie; Lasheras, Juan C.; Singel, Soeren; Varga, Chris

    2001-11-01

    We discuss the results of combined in-vitro laboratory measurements and clinical observations aimed at determining the effect that the unsteady wall shear stresses and the pressure may have on the growth and eventual rupturing of an Abdominal Aortic Aneurysm (AAA), a permanent bulging-like dilatation occurring near the aortic bifurcation. In recent years, new non-invasive techniques, such as stenting, have been used to treat these AAAs. However, the development of these implants, aimed at stopping the growth of the aneurysm, has been hampered by the lack of understanding of the effect that the hemodynamic forces have on the growth mechanism. Since current in-vivo measuring techniques lack the precision and the necessary resolution, we have performed measurements of the pressure and shear stresses in laboratory models. The models of the AAA were obtained from high resolution three-dimensional CAT/SCANS performed in patients at early stages of the disease. Preliminary DPIV measurements show that the pulsatile blood flow discharging into the cavity of the aneurysm leads to large spikes of pressure and wall shear stresses near and around its distal end, indicating a possible correlation between the regions of high wall shear stresses and the observed location of the growth of the aneurysm.

  8. Ultrasonic and X-ray computer tomographic examinations in the diagnosis of pyoinflammatory diseases of the abdominal and retroperitoneal organs

    Comprehensive ultrasonic and x-ray computer-aided tomographic (RCAT) examinations were carried out in 97 patients with 120 pyoinflammatory foci in the abdominal cavity of ultrasonic examinations was 68 %, that of RCAT 88 %. RCAT wassuperior to ultrasonic examinations in the diagnosis of extraorganic. Ultrasonic examinations should be widely used as a primary method and should to a certain measure determine the necessity of RCAT use in the diagnosis of pyoinflammatory diseases of the adbominal cavity and retroperitoneal space organs

  9. Dehydration related abdominal pain (drap)

    Objective: To describe the frequency of dehydration as a medical cause of acute abdomen. Subjects and Methods: All the patients reporting with abdominal pain to the surgical outpatient department or the emergency department were reviewed in the study. The clinical findings in all these cases were studied along with the mode of their management and outcome. Results: Of all the patients presenting with abdominal pain, 3.3% (n=68) were suffering from dehydration related abdominal pain. They were predominantly males in a ratio of 8.7: 1, mostly in the 2nd and 3rd decades of their lives. All these cases were suffering from acute or chronic dehydration were provisionally diagnosed by general practitioners as 'acute abdomen' and referred for surgical consultation. Associated symptoms included vomiting in 42.6%, backache in 91.2%, headache in 95.6%, and pain in lower limbs in 97.1 % of the cases. 83.8% required indoor management with intravenous fluids. All the patients became asymptomatic with rehydration therapy. Conclusion: Dehydration is a possible cause of severe abdominal pain. There is a need to educate the general public about the benefits of adequate fluid intake. (author)

  16. Electromagnetic SCRF Cavity Tuner

    Kashikhin, V.; Borissov, E.; Foster, G.W.; Makulski, A.; Pischalnikov, Y.; Khabiboulline, T.; /Fermilab

    2009-05-01

    A novel prototype of SCRF cavity tuner is being designed and tested at Fermilab. This is a superconducting C-type iron dominated magnet having a 10 mm gap, axial symmetry, and a 1 Tesla field. Inside the gap is mounted a superconducting coil capable of moving {+-} 1 mm and producing a longitudinal force up to {+-} 1.5 kN. The static force applied to the RF cavity flanges provides a long-term cavity geometry tuning to a nominal frequency. The same coil powered by fast AC current pulse delivers mechanical perturbation for fast cavity tuning. This fast mechanical perturbation could be used to compensate a dynamic RF cavity detuning caused by cavity Lorentz forces and microphonics. A special configuration of magnet system was designed and tested.

  17. Superconducting cavity development

    Design and development work of the superconducting cavities for the Neutron Science Project is being continued since 1995. In the cavity design work, RF and structural analyses were carried out in order to determine the cavity shape and to obtain the RF and structural parameters. In the cavity development work, preparation of the test facility, fabrication and tests of the two single-cell prototype cavities of β=0.5 were performed. Good performance of the cavity was demonstrated in the test; obtained surface peak electric field of 44 MV/m is much higher than the design value of 16 MV/m. Resonant frequency shifts due to the vacuum load and the Lorentz force were also measured in the test. (author)

  7. Acupuncture Treatment of Abdominal Pain

    胡金生

    2002-01-01

    @@ Case History Mr. Li, a university student aged 23 years, paid his first visit on July 16, 2001, with the chief complaint of abdominal pain for one day. The patient stated that one day before when it happened to be the weekend, he got abdominal pain after supper, which went worse gradually and caused him to roll all over in bed. The pain was slightly alleviated half an hour later after he had taken some pain killers. Upon inquiry, the patient said that because of their newly graduation from the university, he and his classmates were so excited that they went to have a sumptuous lunch with alcoholic drinks. And in the evening he ate again a delicious supper cooked for him by his mother, after which he continued to have some fruit and dessert.

  8. Intestinal contrasting in abdominal CT

    In 56 patients undergoing abdominal CT the gastro-intestinal tract was defined by negative contrast instead of the conventional positive contrast from an iodine containing contrast medium. The contrast material was a 2 1/2% mannitol solution and was used for filling the rectum. Filling of the gastro-intestinal tract was of similar quality to that obtained with positve contrast media. The number of artifacts due to high contrast boundaries was slightly greater with the negative contrast than if would have been with positive contrast. Differentiation of the gastro-intestinal tract from other abdominal organs was equally good for both methods. The negative contrast method was poor in diagnosing cystic tumours but proved much better than positive contrast for evaluating the wall of the gastro-intestinal tract. (orig.)

  9. Sonography of blunt abdominal trauma

    Sonographic examination of the abdomen after blunt abdominal trauma represents a rapid and effective diagnostic method without bothering the patient. It has proved its value not only in the confirmation or exclusion of free fluid in the abdomen caused by liver of spleen rupture, but also in such cases actually it replaces peritoneal lavage or exploratory laparotomy. It is also qualified for diagnosis of intraparenchymal or subcapsular hemorrhages, intraperitoneal as well as retroperitoneal and for follow up. In particualr delayed bleedings including the risk of a retarded organ rupture can be detected early. A failure rate of 1.4% in 282 sonographically examined cases of blunt abdominal trauma further confirms the reliability of this method. (orig.)

    We studied CT findings and interventional radiology including therapeutic procedures in 43 cases with abdominal blunt trauma, retrospectively. All of parenchymal organ's injuries, and injuries of duodenum and retroperitoneum were correctly diagnosed by CT. In 14 cases with only hemoperitoneum or no positive findings on CT, 4 cases were jejunal perforations, and remaining 10 cases were conservatively treated and relieved. We have to take care that the similar CT findings include the opposite results to need surgery and not. (author)

  12. [A case of abdominal wall actinomycosis].

    Kim, Kyung Hoon; Lee, Jin Soo; Cho, Hyeong Jun; Choi, Seung Bong; Cheung, Dae Young; Kim, Jin Il; Lee, In Kyu

    2015-04-01

    Actinomycosis is a chronic suppurative granulomatous infectious disease caused by actinomyces species that is characterized by formation of characteristic clumps called as sulfur granules. Abdominal actinomycosis is a rare disease and is often difficult to diagnose before operation. Abdominal actinomycosis infiltrating into the abdominal wall and adhering to the colon is even rarer. Most abdominal actinomycosis develops after operation, trauma or inflammatory bowel disease, and is also considered as an opportunistic infection in immunocompromised patient with underlying malignancy, diabetes mellitus, human immunodeficiency virus infection, etc. Actinomycosis is diagnosed based on histologic demonstration of sulfur granules in surgically resected specimen or pus, and treatment consists of long-term penicillin based antibiotics therapy with or without surgical resection. Herein, we report an unusual case of abdominal wall actinomycosis which developed in a patient after acupuncture and presented as abdominal wall mass that was first mistaken for abdominal wall invasion of diverticulum perforation.

    Myneni, Ganapati Rao; Hjorvarsson, Bjorgvin; Ciovati, Gianluigi

    2006-12-19

    A niobium cavity exhibiting high quality factors at high gradients is provided by treating a niobium cavity through a process comprising: 1) removing surface oxides by plasma etching or a similar process; 2) removing hydrogen or other gases absorbed in the bulk niobium by high temperature treatment of the cavity under ultra high vacuum to achieve hydrogen outgassing; and 3) assuring the long term chemical stability of the niobium cavity by applying a passivating layer of a superconducting material having a superconducting transition temperature higher than niobium thereby reducing losses from electron (cooper pair) scattering in the near surface region of the interior of the niobium cavity. According to a preferred embodiment, the passivating layer comprises niobium nitride (NbN) applied by reactive sputtering.

  14. Abdominal wound closure: current perspectives

    Williams ZF

    2015-12-01

    Full Text Available Zachary F Williams, William W Hope Department of Surgery, South East Area Health Education Center, New Hanover Regional Medical Center, Wilmington, NC, USA Abstract: This review examines both early and late wound complications following laparotomy closure, with particular emphasis on technical aspects that reduce hernia formation. Abdominal fascial closure is an area of considerable variation within the field of general surgery. The formation of hernias following abdominal wall incisions continues to be a challenging problem. Ventral hernia repairs are among the most common surgeries performed by general surgeons, and despite many technical advances in the field, incisional hernia rates remain high. Much attention and research has been directed to the surgical management of hernias. Less focus has been placed on prevention of hernia formation despite its obvious importance. This review examines the effects of factors such as the type of incision, suture type and size, closure method, patient risk factors, and the use of prophylactic mesh. Keywords: incisional, abdominal, hernia, prevention, wound closure techniques 

  15. Acute Abdominal Pain in Children.

    Reust, Carin E; Williams, Amy

    2016-05-15

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

  17. Apparatus for treating the walls and floor of the pelvic cavity with radiation

    An apparatus for reaing carcinoma of the walls and floor of the pelvic cavity is described. An elongated tube has an inner end adapted to be placed in the pelvic cavity and an outer end adapted to extend through to the outside of the body. Radioactive material is placed at the inner end. An inner balloon above the radioactive material is inflated to hold a body of liquid shielding material such as mercury. A lower balloon portion beneath the inner balloon spaces areas to be treated such as the walls and floor of the pelvic cavity from the radioactive material. An upper balloon portion above the inner balloon keeps the intestines out of the pelvic cavity and away from the radioactive material. The apparatus is inserted into the pelvic cavity through an abdominal incision. When treating a woman for carcinoma in the walls and floor of the pelvic cavity the tube is moved through the vaginal passage from the inside outwardly. When treating a woman with a closed vaginal passage, as may result from surgery, or when treating a man, such as for carcinoma of the bladder, the tube will pass out of the body through a lower abdominal incision. Following treatment, all balloons are deflated so that the apparatus can be withdrawn through the vaginal passage or the lower abdominal incision, as the case may be. (auth)

  19. Detection of abdominal lymph node metastases from esophageal and cardia cancer by computed tomography

    Shima, S.; Sugiura, Y.; Yonekawa, H.; Ogata, T. (National Defence Medical Coll., Tokorosawa, Saitama (Japan))

    1982-03-01

    In order to evaluate the sensitivity of computed tomography (CT) scan in detecting the abdominal lymph node metastases, preoperative CT scan was performed in 16 patients with carcinoma of the esophagus and gastric cardia. Ten patients (62.5%) had pathological evidence of lymph node metastases in the abdominal cavity and 4 of them were identified to involve the para-aortic nodes. CT scan correctly demonstrated the lymph node metastases in the para-aortic and celiac axisis areas, but failed to detect other abdominal lymph node involvements, which were small enough to be excised by operation. The para-aortic nodes on the CT scan showed the following two features; one was nodular mass in shape, which did not obscure the aorta or inferior vena cava, and the other was conglomerated mass, which was difficult to be distinguished from the aorta. The former was resectable and the latter was not.

  20. Panniculitis of the abdominal wall: Diagnosis by In-111-WBC and radiogallium

    Radioindium imaging (In-111-oxine-white blood cells), performed in a massively obese male, revealed a pattern of activity that was thought to represent a ptotic colon. The patient was restudied with Ga-67 citrate and a similar anterior pattern of activity was noted. On the lateral view of the abdomen, markers established that the activity was external to the abdominal cavity. This corresponded to an active panniculitis which was successfully drained. (orig.)

  3. SPS RF Cavity

    1975-01-01

    The picture shows one of the two initially installed cavities. The main RF-system of the SPS comprises four cavities: two of 20 m length and two of 16.5 m length. They are all installed in one long straight section (LSS 3). These cavities are of the travelling-wave type operating at a centre frequency of 200.2 MHz. They are wideband, filling time about 700 ns and untuned. The power amplifiers, using tetrodes are installed in a surface building 200 m from the cavities. Initially only two cavities were installed, a third cavity was installed in 1978 and a forth one in 1979. The number of power amplifiers was also gradually increased: by end 1980 there were 8 500 kW units combined in pairs to feed each of the 4 cavities with up to about 1 MW RF power, resulting in a total accelerating voltage of about 8 MV. See also 7412017X, 7411048X, 7505074.

  6. Hydroforming of elliptical cavities

    Singer, W.; Singer, X.; Jelezov, I.; Kneisel, P.

    2015-02-01

    Activities of the past several years in developing the technique of forming seamless (weldless) cavity cells by hydroforming are summarized. An overview of the technique developed at DESY for the fabrication of single cells and multicells of the TESLA cavity shape is given and the major rf results are presented. The forming is performed by expanding a seamless tube with internal water pressure while simultaneously swaging it axially. Prior to the expansion the tube is necked at the iris area and at the ends. Tube radii and axial displacements are computer controlled during the forming process in accordance with results of finite element method simulations for necking and expansion using the experimentally obtained strain-stress relationship of tube material. In cooperation with industry different methods of niobium seamless tube production have been explored. The most appropriate and successful method is a combination of spinning or deep drawing with flow forming. Several single-cell niobium cavities of the 1.3 GHz TESLA shape were produced by hydroforming. They reached accelerating gradients Eacc up to 35 MV /m after buffered chemical polishing (BCP) and up to 42 MV /m after electropolishing (EP). More recent work concentrated on fabrication and testing of multicell and nine-cell cavities. Several seamless two- and three-cell units were explored. Accelerating gradients Eacc of 30 - 35 MV /m were measured after BCP and Eacc up to 40 MV /m were reached after EP. Nine-cell niobium cavities combining three three-cell units were completed at the company E. Zanon. These cavities reached accelerating gradients of Eacc=30 - 35 MV /m . One cavity is successfully integrated in an XFEL cryomodule and is used in the operation of the FLASH linear accelerator at DESY. Additionally the fabrication of bimetallic single-cell and multicell NbCu cavities by hydroforming was successfully developed. Several NbCu clad single-cell and double-cell cavities of the TESLA shape have been

    2003-01-01

    ""Cavity-Enhanced Spectroscopy"" discusses the use of optical resonators and lasers to make sensitive spectroscopic measurements. This volume is written by the researcchers who pioneered these methods. The book reviews both the theory and practice behind these spectroscopic tools and discusses the scientific discoveries uncovered by these techniques. It begins with a chapter on the use of optical resonators for frequency stabilization of lasers, which is followed by in-depth chapters discussing cavity ring-down spectroscopy, frequency-modulated, cavity-enhanced spectroscopy, intracavity spectr

  8. FULL TERM EXTRAUTERINE ABDOMINAL PREGNANCY

    Neetu

    2014-02-01

    Full Text Available Extrauterine abdominal pregnancy is extremely rare and is frequently missed during antenatal care, despite the routine use of obstetrics ultrasound. A 23 year old primigravida at 39 weeks of gestation was admitted to the department on December 2 , 2012, in routine hour with transverse lie with oligohydramnios. On examination her vitals and laboratory investigation were within normal limits . One of the ultrasonographic scanning done by radiologist at 35 wk. 3 days gestation demonstrated a single live intrauterine fetus of CGA 33 wk. 1 day with transverse lie , fundal gr II placenta and AFI - 10 cm. Ultrasonography done at the department on the day of admission demonstrated single live intrauterine fetus with transverse lie and AFI - 3.8 cm and EFW 2.4 Kg and placenta was right anterior.. She was planned for elective caesarean section on account of transverse lie and oligohydramnios at term. At laparotomy the following findings were made: Secondary abdominal pregnancy arising from right tubal ectopic rupture and making pseudogesta tional sac with meconium stained liquor. Omentum , right tube and ovary were adhered to sac. The uterus and left tube and ovary were healthy and normal . Other abdominal organs were normal. A 1.5 Kg live male baby with good Apgar score and incompletely formed mandible extracted from pseudo gestational sac. There was significant bleeding from pseudogestational sac and patient went in shock during intraoperative period. One unit whole blood transfused during intraoperative period. Placenta was adherent to the pseudogestational sac so Psudogestational sac was removed with placenta in situ and right sided salpingo - o ophrectomy was also done due to their adherence. Hemostasis was secured. The patient and baby progressed well and were discharged on the seventh postoperative day

  9. accelerating cavity from LEP

    This is an accelerating cavity from LEP, with a layer of niobium on the inside. Operating at 4.2 degrees above absolute zero, the niobium is superconducting and carries an accelerating field of 6 million volts per metre with negligible losses. Each cavity has a surface of 6 m2. The niobium layer is only 1.2 microns thick, ten times thinner than a hair. Such a large area had never been coated to such a high accuracy. A speck of dust could ruin the performance of the whole cavity so the work had to be done in an extremely clean environment. These challenging requirements pushed European industry to new achievements. 256 of these cavities are now used in LEP to double the energy of the particle beams.

  10. Moving Detectors in Cavities

    Obadia, N

    2007-01-01

    We consider two-level detectors, coupled to a quantum scalar field, moving inside cavities. We highlight some pathological resonant effects due to abrupt boundaries, and decide to describe the cavity by switching smoothly the interaction by a time-dependent gate-like function. Considering uniformly accelerated trajectories, we show that some specific choices of non-adiabatic switching have led to hazardous interpretations about the enhancement of the Unruh effect in cavities. More specifically, we show that the emission/absorption ratio takes arbitrary high values according to the emitted quanta properties and to the transients undergone at the entrance and the exit of the cavity, {\\it independently of the acceleration}. An explicit example is provided where we show that inertial and uniformly accelerated world-lines can even lead to the same ``pseudo-temperature''.

  11. SPS accelerating cavity

    1976-01-01

    The SPS started up with 2 accelerating cavities (each consisting of 5 tank sections) in LSS3. They have a 200 MHz travelling wave structure (see 7411032 and 7802190) and 750 kW of power is fed to each of the cavities from a 1 MW tetrode power amplifier, located in a surface building above, via a coaxial transmission line. Clemens Zettler, builder of the SPS RF system, is standing at the side of one of the cavities. In 1978 and 1979 another 2 cavities were added and entered service in 1980. These were part of the intensity improvement programme and served well for the new role of the SPS as proton-antiproton collider. See also 7411032, 8011289, 8104138, 8302397.

    2014-01-01

    Abdominal Aortic Aneurysm (AAA) is a common disease with a prevalence of 1.5-2.0% in 65-year old men in Sweden. The risk of having AAA is increased with smoking, high age, family history of AAA and cardiovascular disease. Women have a lower prevalence (0.5%) and develop AAA later in life. An AAA seldom gives any symptom prior to rupture. Untreated rupture is associated with 100% mortality, while surgically treated rupture is associated with 25-70% mortality. Prophylactic sur...

  15. Abdominal manifestations of autoimmune disorders

    Full text: Immunoglobulin G4-related disease was recognized as a systemic disease since various extrapancreatic lesions were observed in patients with autoimmune pancreatitis (AIP). The real etiology and pathogenesis of IgG4-RD is still not clearly understood. Moreover the exact role of IgG4 or IgG4-positive plasma cells in this disease has not yet been elucidated. only some inconsistent biological features such as hypergammaglobulinemia or hypocomplementemia support the autoimmune nature of the disease process. various names have been ascribed to this clinicopathological entity including IgG4-related sclerosing disease, IgG4-related systemic sclerosing disease, IgG4-related disease, IgG4-related autoimmune disease, hyper-IgG4 disease and IgG4-related systemic disease. The extrapancreatic lesions of IgG4-RD also exhibit the same characteristic histologic features including dense lymphoplasmacytic infiltrate, massive storiform fibrosis, and obliterative phlebitis as seen in IgG4-related pancreatitis. Abdominal manifestations include the following organs/systems: Bile ducts: Sclerosing cholangitis; Gallbladder and liver: Acalculous sclerosis cholecytitis with diffuse wall thickening; hepatic inflammatory pseudotumorts; Kidneys: round or wedge-shaped renal cortical nodules, peripheral cortical; lesions, mass like lesions or renal pelvic involvement; Prostate, urethra, seminal vesicle, vas deferens, uterine cervix; Autoimmune prostatitis; Retroperitoneum: Retroperitoneal fibrosis. thin or mildly thick homogeneous soft tissue lesion surrounding the abdominal aorta and its branches but also bulky masses causing hydronephroureterosis; Mesentery: Sclerosing mesenteritis usually involving the root of the mesentery; Bowel: Inflammatory bowel diseases mimicking Crohn’s disease or ulcerative colitis. various types of sclerosing nodular lesions of the bowel wall; Stomach: Gastritis, gastric ulcers and focal masses mimicking submucosal tumor; omentum: Infiltration mimicking

    Although leprosy involves the oral cavity in up to 60% of the patients, examination of the oral cavity in leprosy clinics or oral health science clinics is often neglected. Oral involvement in leprosy can broadly be divided into non-specific and specific lesions. In this review, we discuss various oral manifestations in leprosy patients so as to increase the awareness about this aspect among dermatologists and dental surgeons.

    2009-01-01

    Abstract: During insufflation of the abdomen to create a pneumoperitoneum for laparoscopy, both intra abdominal pressure and insufflated volume can be measured and are used to calculate the abdominal pressure-volume relationship. First, an accurate, linear relationship was identified using a mathematical model with an elastance, E, or its reciprocal the compliance C and with a pressure at zero volume, PV0. This function was stable and could be used to describe the abdominal characteristics of...

  2. Abdominal Wall Abscess due to Acute Perforated Sigmoid Diverticulitis: A Case Report with MDCT and US Findings

    Rafailidis Vasileios

    2013-01-01

    Full Text Available Perforation of the inflamed diverticula is a common diverticulitis complication. It usually leads to the formation of a local abscess. In some rare cases, the inflammatory process may spread towards extra-abdominal sites like the anterior or posterior abdominal wall or the thigh and form an abscess in these sites. We present the case of a 73-year-old man with a history of pain at the lower left quadrant of the abdomen for 20 days and a visible mass in this site. Ultrasonography and computed tomography revealed this mass to be an abscess of the abdominal wall which had been formed by the spread of ruptured sigmoid diverticulitis by continuity of tissue through the lower left abdominal wall. Local drainage of the abscess was performed and the patient was discharged after alleviation of symptoms and an uneventful course. We also discuss causes of abdominal wall abscesses along with the possible pathways by which an intra-abdominal abscess could spread outside the abdominal cavity.

    Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management.

  5. Percutaneous drainage of abdominal abcess

    Men, Sueleyman E-mail: suleyman.men@deu.edu.tr; Akhan, Okan; Koeroglu, Mert

    2002-09-01

    The mortality in undrained abdominal abscesses is high with a mortality rate ranging between 45 and 100%. The outcome in abdominal abscesses, however, has improved due to advances in image guided percutaneous interventional techniques. The main indications for the catheter drainage include treatment or palliation of sepsis associated with an infected fluid collection, and alleviation of the symptoms that may be caused by fluid collections by virtue of their size, like pancreatic pseudocele or lymphocele. The single liver abscesses may be drained with ultrasound guidance only, whereas the multiple abscesses usually require computed tomography (CT) guidance and placement of multiple catheters. The pancreatic abscesses are generally drained routinely and urgently. Non-infected pancreatic pseudocysts may be simply observed unless they are symptomatic or cause problems such as pain or obstruction of the biliary or the gastrointestinal tract. Percutaneous routes that have been described to drain pelvic abscesses include transrectal or transvaginal approach with sonographic guidance, a transgluteal, paracoccygeal-infragluteal, or perineal approach through the greater sciatic foramen with CT guidance. Both the renal and the perirenal abscesses are amenable to percutaneous drainage. Percutaneous drainage provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses as well.

  6. Abdominal ultrasound in AIDS patients

    To analyze the ultrasonography findings in abdomen in the AIDS patients in our hospital, as well as the indications for this exploration, assessing the role of abdominal ultrasound (AU). The ultrasonographic and clinical findings in 527 patients who underwent a total of 715 explorations between 1992 and 1996 were studied. Hepatomegaly and/or splenomegaly, usually homogeneous, were observed in nearly half of the studies (45%); one third of the patients with marked splenomegaly presented visceral leishmaniasis. Focal lesions in liver and/or spleen, corresponding to angiomas, abscesses, lymphomatous lesions and metastasis, were detected in 5.7% of the explorations. Thirty-five percent of the AU revealed the presence of lymphadenopathy; nodes measuring over 2.5 cm were usually related to potential treatable infection or neoplasm. Thickening of the gallbladder wall did not usually indicate the presence of acute cholecystitis unless Murphy''s sign was also detected. Bile duct dilation and wall thickening was related to opportunistic cholangitis, and the increase in the echogenicity of the renal parenchyma was linked to AIDS-related nephropathy. Despite the fact that many of findings with AU are nonspecific, we consider that this approach should be the principal diagnostic technique in AIDS patients with suspected abdominal pathology or fever of unknown origin.

  7. Major abdominal evisceration injuries in dogs and cats: 12 cases (1998-2008).

    Gower, Sara B; Weisse, Chick W; Brown, Dorothy C

    2009-06-15

    OBJECTIVE- To describe the clinical characteristics, treatment, complications, and outcome of dogs and cats treated surgically for major abdominal evisceration. DESIGN- Retrospective case series. ANIMALS- 8 dogs and 4 cats. PROCEDURES- Medical records from January 1998 through March 2008 were reviewed to identify animals that underwent surgery for major abdominal evisceration. Data regarding cause of evisceration, signalment, physiologic variables, and hematologic variables were collected. Details of treatment, duration of hospitalization, and outcome were recorded. Linear regression analysis was performed to evaluate the association of signalment, physiologic variables, and hematologic variables on the number of days of hospitalization. RESULTS- Major abdominal evisceration was secondary to a traumatic event in 4 animals and to postsurgical dehiscence in 8 animals. All animals had evisceration of the intestines and gross contamination with dirt, leaves, or litter. Two animals eviscerated the spleen, and 1 animal had a perforated colon and was leaking feces into the peritoneal cavity. All animals underwent exploratory abdominal surgery. Surgical procedures performed included resection of compromised intestine, body wall repair, diaphragmatic hernia repair, nephrectomy, splenectomy, and primary colonic repair. All animals survived to discharge from the hospital. Median duration of hospitalization was 4 days (range, 1 to 7 days). Factors associated with an increase in duration of hospitalization included evisceration secondary to trauma, high lactate concentration at time of admission, and small body size. CONCLUSIONS AND CLINICAL RELEVANCE- Despite the dramatic appearance of major abdominal evisceration in cats and dogs, prompt and aggressive medical and surgical intervention can provide a favorable outcome.

  8. EVENTRATION OF LEFT HEMIDIAPHRAGM MIMICKING AS CAVITY

    Kansal

    2015-10-01

    Full Text Available Eventration of diaphragm is a condition in which there is abnormal elevation of the diaphragm as a result of thinning of muscular layer. It can be congenital as well as acquired. It is more common left sided. Herniation of the abdominal contents can be there. Clinical manifestations range from asymptomatic to life threatening respiratory distress requiring mechanical ventilator support. Ultrasound provides valuable information regarding the integrity of the diaphragm. Other imaging modalities include fluoroscopy, CT and MRI that provide valuable information when diagnosis is in doubt. We are presenting a case report of 25-year-old male with eventration of left hemidiaphragm mimicking as cavity. After taking detail history, examination and proper investigations we finally reached to this diagnosis.

  9. Abdominal Manifestations of Lymphoma: Spectrum of Imaging Features

    Non-Hodgkin and Hodgkin lymphomas frequently involve many structures in the abdomen and pelvis. Extranodal disease is more common with Non-Hodgkin's lymphoma than with Hodgkin's lymphoma. Though it may be part of a systemic lymphoma, single onset of nodal lymphoma is not rare. Extranodal lymphoma has been described in virtually every organ and tissue. In decreasing order of frequency, the spleen, liver, gastrointestinal tract, pancreas, abdominal wall, genitourinary tract, adrenal, peritoneal cavity, and biliary tract are involved. The purpose of this review is to discuss and illustrate the spectrum of appearances of nodal and extranodal lymphomas, including AIDS-related lymphomas, in the abdominopelvic region using a multimodality approach, especially cross-sectional imaging techniques. The most common radiologic patterns of involvement are illustrated. Familiarity with the imaging manifestations that are diagnostically specific for lymphoma is important because imaging plays an important role in the noninvasive management of disease

  10. Diagnostic application of labelled leukocytes in gastroenterology and abdominal surgery

    A total of 18 patients suspected of inflammatory process or abcessus in the abdominal cavity have been studied by scintiscanning with autologous leukocytes labelled with 111In-oxine (10-12 MBq) or 99mTc-HMPAO (300 MBq). Evaluation of the process activity is done on the ground activity index adopted which is received after the computer processing of the results. Three levels of process activity are determined: 1) when the leukocyte accumulation (LA) corresponds to that in the bone marrow; 2) when the LA corresponds to that in the liver; 3) when the LA corresponds to that in the spleen. The recorded sensitivity, specificity and accuracy of the method amount to 87.5%, 100% and 92.9% respectively. The method allows localization of the inflammatory process and indicates the degree of affecting the intestines. 2 figs., 6 refs

  11. Tomographically computed x-ray studies on the subcutaneous fatty layer of the lower abdominal plane

    (1) The cross-sectional area in the adult lower abdomen increased with age until a certain age and it decreased rapidly with old age in male, but there was little decreasing tendency in old age in female. (2) As for the cross-sectional area of the various tissue layers, that of the abdominal cavity was the greatest for both upper and lower planes, and this was followed by the subcutaneous fatty layer, muscular layer, osseous layer, in terms of size, in the upper plane. On the other hand, the cross-sectional area of the abdominal cavity was followed in size by the muscular layer in males and the subcutaneous fatty layer in females in the lower plane. (3) Concerning the age-related changes of the cross-sectional areas of the various tissue layers, it was observed in the elderly subjects that the males showed decreasing tendencies in the cross-sectional areas of the abdominal cavity and subcutaneous fatty layer, while the females showed increasing tendencies in the abdominal cavity but decreasing tendencies in the subcutaneous fatty layer. (4) As for the subcutaneous fatty layer thicknesses in the cross-sectional area, the gluteal line area was the largest and followed by the lumbar area in the upper plane. In contrast to this, in the lower plane, the thickness in the gluteal region was the largest for both males and females, and this was followed by the lumbar line region in males and the lateral line region in females. (5) As for the female minors, the total cross-sectional areas were 70 % of that of the adults, and the cross-sectional areas of the respective tissue layers also showed the same proportions under 10 years old. In the teenagers, too, the total cross-sectional areas were considerably smaller compared to the adults, but the cross-sectional areas of the various tissue layers were roughly equal to the adults except for the abdominal cavity area which alone was smaller.

    Introduction Negative pressure wound therapy (NPWT) for abdominal surgical site infection (SSI) is becoming increasingly common, although enterocutaneous fistula (ECF) has been reported as a complication. To avoid ECF, we used computed tomography (CT) woundgraphy to evaluate the relationship between the wound and the intestine, and then safely treated the abdominal SSI with NPWT. Case presentation Following a laparoscopic intersphincteric resection for low rectal neuroendocrine tumor and covering ileostomy, a 59-year-old woman underwent stoma closure. Six days after surgery, we diagnosed SSI. We suspected ECF, because the wound was deep and the pus resembled enteric fluid. However, CT woundgraphy showed that the wound was separated from the abdominal cavity and the intestine by the abdominal rectus muscle. Accordingly, we performed NPWT. SSI was cured and the wound was well granulated. Twenty-three days after surgery, the patient was discharged. Eventually, the wound was completely epithelialized. Discussion Although successful NPWT has been reported for open abdominal wounds, ECF is a common complication. ECF can be prevented by separating the wound from the intestine by the omentum or muscle fascia, protecting the intestinal serosa during surgery, and applying low vacuum pressure. The relationships among the wound, the fascia, and the intestine must be evaluated before abdominal SSI treatment. One good method is CT woundgraphy, which evaluates wound extent and depth, closure of muscle fascia, and the relationship between the wound and the intestine. Conclusion We report a case of CT woundgraphy before NPWT for abdominal SSI. CT woundgraphy is a good candidate for evaluating wound condition. PMID:27002290

  13. Secondary abdominal pregnancy and its associated diagnostic and operative dilemma: three case reports

    2009-08-01

    Full Text Available Abstract Introduction Abdominal pregnancy is extremely rare and has historically been defined as an implantation in the peritoneal cavity, exclusive of tubal, ovarian or intraligamentary pregnancy. Case presentations Three cases are reported. All came from a lower middle-income group and all of them were subjected to surgery. The first patient was a 30-year-old woman, who was pregnant for the fourth time, who presented at 16 weeks with an abdominal pregnancy. She was admitted with constant abdominal pain and retention of urine. She was hemodynamically stable and was administered a pre-operative intramuscular injection of methotrexate. During laparotomy she had only minor blood loss, the major part of the placenta was removed easily and she did not require any blood transfusion. Serum beta human chorionic gonadotrophin values and ultrasound follow-up revealed a normal study four weeks after surgery. The second patient was a 26-year-old woman, pregnant for the third time, admitted at 14 weeks with an abdominal pregnancy with hemoperitoneum, and the third patient was a 24-year-old woman, pregnant for the first time, who presented at 36 weeks gestation. She was only diagnosed as having an abdominal pregnancy during surgery, experienced excessive blood loss and required a longer hospital stay. Conclusions We hypothesize that treatment with pre-operative systemic methotrexate with subsequent laparotomy for removal of the fetus and placenta may minimize potential blood loss, and would be a reasonable approach in the care of a patient with an abdominal pregnancy with placental implantation to the abdominal viscera and blood vessels. This treatment option should be considered in the management of this potentially life-threatening condition. During surgery, if the placenta is attached to vital organs it should be left behind. Early diagnosis can help in reducing associated maternal morbidity and mortality.

  14. Retained intra-abdominal artery forceps – An unusual cause of intestinal strangulation

    2011-07-01

    Full Text Available Context: Surgical instruments and materials continue to be retained in the peritoneal cavity despite precautionary measures. Even though uncommon it is also under-reported and carries serious medico-legal consequences. Gauzes and sponges (gossypiboma are the most commonly retained materials and intra-abdominal retained artery forceps are much rarer but when they do occur lead to chronic abdominal pain and can be a rare cause of intestinal obstruction or strangulation with significant morbidity and mortality. Case Report: We present a case of intraabdominal retained artery forceps in a 70-years-old lady who underwent laparotomy with splenectomy for a large spleen in a peripheral hospital. Upon discharge she continued to complain of intermittent abdominal pain of increasing severity. 12 months later she presented to us with an acute (surgical abdomen requiring another laparotomy. At laparotomy she had strangulated/gangrenous lower jejunual and upper ileal bowel loops, the small bowel mesentery of this area being tightly trapped between the jaws of the retained artery forceps. She had gut resection and enteroanastomosis. Unfortunately she died from continuing sepsis on the second post-operative day. Conclusion: Retained instruments in intra-abdominal surgery can cause serious complication and should be treated surgically. High index of suspicion and appropriate investigations like plain abdominal X-ray, abdominal ultrasound and CT and MRI scans should be instituted in patients who develop chronic abdominal symptoms following laparotomy. Preventive measures against retained instruments must follow strict laid down protocols for surgical instruments handling in theatre.

    Yamada, Sohsuke; Tanimoto, Akihide; Matsuki, Yasumasa; Hisada, Yuji; Sasaguri, Yasuyuki

    2009-09-01

    A case of sclerosing encapsulating peritonitis (SEP) associated with liver cirrhosis (LC) and complicated by diffuse large B-cell lymphoma (DLBCL) is reported herein. A 49-year-old Japanese man had undergone peritoneo-venous shunt against refractory ascites due to hepatitis C virus-positive uncompensated LC for 2 years. After he received a diagnosis of DLBCL of the left neck lymph node 3 months before his death, palliative care was given because of his poor general condition. He developed severe abdominal distention and pain over 1 week and was found to have marked ascites and whole bowel lumped together on abdominal CT. At autopsy, the peritoneum was covered with a thick white membrane and the bowel could not be distinguished, which was macroscopically characterized by a cocoon-like appearance. Histology indicated a proliferation of diffusely thickened or hyalinized fibrocollagenous tissue in the entire peritoneum with a slight chronic inflammatory infiltrate and without remarkable change of mucosa. A diagnosis of SEP, also known as abdominal cocoon, was established based on these features. Additionally, in the abdominal cavity, a large amount of serous ascites and multiple peritoneal nodules or masses involved by DLBCL were recognized.

  18. Abdominal Wall Modification for the Difficult Ostomy

    Beck, David E.

    2008-01-01

    A select group of patients with major stomal problems may benefit from operative modification of the abdominal wall. Options may include a modified abdominoplasty (abdominal wall contouring), localized flaps, or liposuction. Although frequently successful, these techniques have the potential for significant morbidity.

  19. Synovial sarcoma of the abdominal wall

    A case report of synovial sarcoma arising in the abdominal wall is presented. A brief review of the clinical and radiological features of synovial sarcoma is made. Pre-operative diagnosis of an abdominal wall synovial sarcoma is virtually impossible, but should be considered when a soft tissue swelling is found to show amorphous stippled calcification X-ray.

  1. Hypoxia inhibits abdominal expiratory nerve activity.

    Our purpose was to examine the influence of steady-state changes in chemical stimuli, as well as discrete peripheral chemoreceptor stimulation, on abdominal expiratory motor activity. In decerebrate, paralyzed, vagotomized, and ventilated cats that had bilateral pneumothoraces, we recorded efferent activity from a phrenic nerve and from an abdominal nerve (cranial iliohypogastric nerve, L1). All cats showed phasic expiratory abdominal nerve discharge at normocapnia [end-tidal PCO2 38 +/- 2 Torr], but small doses (2-6 mg/kg) of pentobarbital sodium markedly depressed this activity. Hyperoxic hypercapnia consistently enhanced abdominal expiratory activity and shortened the burst duration. Isocapnic hypoxia caused inhibition of abdominal nerve discharge in 11 of 13 cats. Carotid sinus nerve denervation (3 cats) exacerbated the hypoxic depression of abdominal nerve activity and depressed phrenic motor output. Stimulation of peripheral chemoreceptors with NaCN increased abdominal nerve discharge in 7 of 10 cats, although 2 cats exhibited marked inhibition. Four cats with intact neuraxis, but anesthetized with ketamine, yielded qualitatively similar results. We conclude that when cats are subjected to steady-state chemical stimuli in isolation (no interference from proprioceptive inputs), hypercapnia potentiates, but hypoxia attenuates, abdominal expiratory nerve activity. Mechanisms to explain the selective inhibition of expiratory motor activity by hypoxia are proposed, and physiological implications are discussed. PMID:3624126

  3. Fetal abdominal magnetic resonance imaging

    This review deals with the in vivo magnetic resonance imaging (MRI) appearance of the human fetal abdomen. Imaging findings are correlated with current knowledge of human fetal anatomy and physiology, which are crucial to understand and interpret fetal abdominal MRI scans. As fetal MRI covers a period of more than 20 weeks, which is characterized not only by organ growth, but also by changes and maturation of organ function, a different MR appearance of the fetal abdomen results. This not only applies to the fetal intestines, but also to the fetal liver, spleen, and adrenal glands. Choosing the appropriate sequences, various aspects of age-related and organ-specific function can be visualized with fetal MRI, as these are mirrored by changes in signal intensities. Knowledge of normal development is essential to delineate normal from pathological findings in the respective developmental stages

    A vertical-external-cavity surface-emitting-laser is demonstrated in the terahertz range, which is based upon an amplifying metasurface reflector composed of a sub-wavelength array of antenna-coupled quantum-cascade sub-cavities. Lasing is possible when the metasurface reflector is placed into a low-loss external cavity such that the external cavity—not the sub-cavities—determines the beam properties. A near-Gaussian beam of 4.3° × 5.1° divergence is observed and an output power level >5 mW is achieved. The polarized response of the metasurface allows the use of a wire-grid polarizer as an output coupler that is continuously tunable.

  7. Experimental investigation of cavity flows

    Loeland, Tore

    1998-12-31

    This thesis uses LDV (Laser Doppler Velocimetry), PIV (Particle Image Velocimetry) and Laser Sheet flow Visualisation to study flow inside three different cavity configurations. For sloping cavities, the vortex structure inside the cavities is found to depend upon the flow direction past the cavity. The shape of the downstream corner is a key factor in destroying the boundary layer flow entering the cavity. The experimental results agree well with numerical simulations of the same geometrical configurations. The results of the investigations are used to find the influence of the cavity flow on the accuracy of the ultrasonic flowmeter. A method to compensate for the cavity velocities is suggested. It is found that the relative deviation caused by the cavity velocities depend linearly on the pipe flow. It appears that the flow inside the cavities should not be neglected as done in the draft for the ISO technical report on ultrasonic flowmeters. 58 refs., 147 figs., 2 tabs.

  8. Imaging of the peritoneal cavity in CAPD.

    Wankowicz, Z; Pietrzak, B; Skrobowska, E

    1996-01-01

    The aim of our study was the use of the optimal imaging of the peritoneal cavity (PC) for continuous ambulatory peritoneal dialysis (CAPD)-related problems. Ultrasonography (USG), direct abdominal radiography (DAR), peritoneoscintigraphy (PSG), and standard peritoneo-computed tomography (PCT) with reconstruction (R-PCT) were performed in 25 patients on CAPD from three to 44 months. Studies were done at the beginning of CAPD (1-3 months) as well as in the noncomplicated and complicated course of CAPD. Group 1 comprised 17 patients in whom 77 PC images were taken in the non-complicated course of CAPD. Group II comprised 15 patients in whom 65 images were taken during or after complications. For USG and DAR we used standard equipment, PSG was done with sulfur colloid labeled with technetium 99m (Tc 99m), PCT, and R-PCT were done with Omnipaque and Somatom HiQ Siemens unit. In PCT, two- and three dimensional reconstruction were done by our own computer program. USG was recommended for imaging of tunnel infections, exit-site infection (ESI), and adhesion. PSG was useful in almost all observed complications of CAPD except thickening of the peritoneal membrane (PM). Standard PCT with R-PCT was more useful than PCT because of a more legible image of the peritoneal cavity, which gives the possibility of monitoring fluid distribution and measuring of intraperitoneal fluid volume.

    1993-01-01

    Two approachs of modelling nonhomogeneous cavity laser are presented. They are based on the beam propagation method which allows the use of fast Fourier transform (FFT). The resulting procedures provide selfconsistent solutions to the Maxwell and diffusion equations. Results are given to illustrate the two methods.
