  2. Mini-laparotomy with abdominal wall lifting for partial gastrectomy in patients with early gastric mucosal cancer at lesser curvature of the middle stomach. (United States)

    Tomita, Ryouichi; Fujisak, Shigeru; Park, Yeong Ji


    Partial gastrectomy (PG) is the most frequently adopted minimally invasive procedure for early gastric cancer (EGC), especially mucosal cancer (MC). The aim of this study was to introduce a minimally invasive procedure, i.e., minilaparotomy with abdominal wall lifting for PG in patients with early mucosal gastric cancer at the lesser curvature of the middle stomach. Well differentiated adenocarcionoma in MC at the lesser curvature of the middle stomach was selected, where no lymph node metastasis (NO) was confirmed using ultrasonic endoscopy, CT, and MRI during the preoperative examinations. PG was also chosen for patients with a tumor size of 2cm or less and non-depressive type in whom endoscopic mucosal resection (EMR) or endoscopic submucosal resection (ESD) was not possible. Five MC patients (3 men and 2 women, aged 44-62 years, mean age 53.3 years) underwent mini-laparotomy with abdominal wall lifting for PG. Our procedure involved a 6 cm upper abdominal median incision made at the beginning of the operation. The upper abdominal wall was lifted by a subcutaneous Kirshner wire. The small wound was also pulled upward and/or laterally by Kent retractors and conventional surgical instruments were used through the wound. The middle stomach could be detected through the small wound and partially resected, approximately 1 cm from the tumor edge under the guide of the endoscope. The resected stomach margin was stitched layer-to-layer. In this way, PG was easily completed. The total surgical time was 71.8 +/- 12.9 min and the mean estimated blood loss was 30.8 +/- 20.5 ml. Day of starting diet was 3 +/- 0.7 days after operation. Post-operative hospitalization was 8.2 +/- 1.3 days. There was no surgical mortality. All subjects were satisfied with this procedure. Mini-laparotomy with abdominal wall lifting is a safe and efficient technique in the treatment of PG for MC with NO at the lesser curvature of the middle stomach when EMR or ESD is impossible.

    Systemic lupus erythematosus(SLE) is a systemic disease of unknown etiology. Its main pathology is vasculitis and serositis, due to deposition of the immune complex or antibodies. Most findings are nonspecific ; abdominal manifestations include enteritis, hepatomegaly, pancreatic enlargement, serositis, lymphadenopathy, splenomegaly, nephritis, interstitial cystitis, and thrombophlebitis. We described radiologic findings of various organ involvement of SLE; digestive system, serosa, reticuloendothelial system, urinary system, and venous system. Diagnosis of SLE was done according to the criteria of American Rheumatism Association. Understanding of the variable imaging findings in SLE may be helpful for the early detection of abdominal involvement and complications.

  8. Abdominal obesity, cardiometabolic risk and endocannabinoid system

    Directory of Open Access Journals (Sweden)

    G. Bittolo Bon


    Full Text Available Abdominal obesity is the most prevalent manifestation of metabolic syndrome and is of central importance in the definition of global cardiometabolic risk. Visceral adipose tissue releases a large number of bioactive mediators, which influence body weight homeostasis, insulin resistance, alterations in lipids, blood pressure, coagulation, fibrinolysis and inflammation, leading to increased risk of cardiovascular events and of type 2 diabetes. Lifestyle modification is the first-line approach to the management of abdominal obesity and metabolic syndrome. However for patients at higher risk, who cannot achieve an appreciable reduction in weight and in global cardiometabolic risk with lifestyle modification alone, an adjunctive long term pharmacotherapy should be considered. The endocannabinoid system activity regulates food intake and metabolic factors through cannabinoid-1 (CB1 receptor located in multiple sites, including hypothalamus and limbic forebrain, adipose tissue, skeletal muscle, liver and the gastrointestinal tract. Evidence suggests that CB1 receptor blockade offers a novel therapeutic strategy. Data from four phase III trials suggest that rimonabant, the first cannabinoid receptor inhibitor, modulates cardiometabolic risk factors, both through its impact on body weight and metabolic parameters such as HDL-cholesterol, tryglicerides, Hb1Ac, through direct pathways that are not related to weight loss.

    Objectives: Trauma is among the leading causes of death. Medical management of blunt abdominal trauma (BAT) relies on judging patients for whom laparotomy is mandatory. This study aimed to determine BAT patients' signs, as well as paraclinical data, and to clarify the accuracy, sensitivity, specificity, positive and negative predictive value of clinical abdominal scoring system (CASS), a new scoring system based on clinical signs, in predicting whether a BAT patient needs laparotomy or not.Methods: Totally 400 patients suspected of BAT that arrived at the emergency department of two university hospitals in Tehran from March 20, 2007 to March 19, 2009 were included in this study. They were evaluated for age, sex,type of trauma, systolic blood pressure, Glasgow coma scale (GCS), pulse rate, time of presentation after trauma, abdominal clinical findings, respiratory rate, temperature, hemoglobin (Hb) concentration, focused abdominal sonography in trauma (FAST) and CASS.Results: Our measurements showed that CASS had an accuracy of 94%, sensitivity of 100%, specificity of 88%,positive predictive value of 90% and negative predictive value of 100% in determining the necessity of laparotomy in BAT patients. Moreover, in our analysis, systolic blood pressure, GCS, pulse rate, Hb concentration, time of presentation after trauma, abdominal clinical findings and FAST were also shown to be helpful in confirming the need for laparotomy (P<0.05).Conclusion: CASS is a promising scoring system in rapid detection of the need for laparotomy as well as in minimizing auxiliary expense for further evaluation in BAT patients, thus to promote the cost-benefit ratio and accuracy of diagnosis.

  12. Size selectivity in field-flow fractionation: lift mode of retention with near-wall lift force. (United States)

    Martin, Michel; Beckett, Ronald


    A simple theoretical model for the size selectivity, S(d), in the lift mode of retention in field-flow fractionation (FFF) is developed on the basis of the near-wall lift force expression. S(d) is made up of two contributions: the flow contribution, S(d,f), arising from the variation of the flow velocity at center of particle due to a change in particle position with particle size, and a slip contribution, S(d,s), arising from the concomitant change in the extent of retardation due to the presence of a nearby channel wall. The slip contribution is minor, but not negligible, and amounts to 10-20% of the overall size selectivity. It contributes to reduce S(d) in sedimentation FFF but to enhance it in flow FFF. S(d) would steadily increase with particle size if the flow profile was linear (Couette flow). Because of the curvature of the flow profile encountered in the classical Poiseuille flow, S(d) exhibits a maximum at some specific particle size. The model predicts a significant difference in S(d) between sedimentation FFF and flow FFF, arising from the different functional dependences of the field force with particle size between these two methods. The predictions are in good agreement with the various S(d) values reported in the literature in both sedimentation and flow FFF. On the basis of the model, guidelines are given for adjusting the operating parameters (carrier flow rate and field strength) to optimize the size selectivity. Finally, it is found that S(d) generally decreases with decreasing channel thickness.

    Percutaneous abdominal puncture is a popular interventional method for the management of abdominal tumors. Image-guided puncture can help interventional radiologists improve targeting accuracy. The second generation of Kinect™ was released recently, we developed an optical navigation system to investigate its feasibility for guiding percutaneous abdominal puncture, and compare its performance on needle insertion guidance with that of the first-generation Kinect™. For physical-to-image registration in this system, two surfaces extracted from preoperative CT and intraoperative Kinect™ depth images were matched using an iterative closest point (ICP) algorithm. A 2D shape image-based correspondence searching algorithm was proposed for generating a close initial position before ICP matching. Evaluation experiments were conducted on an abdominal phantom and six beagles in vivo. For phantom study, a two-factor experiment was designed to evaluate the effect of the operator’s skill and trajectory on target positioning error (TPE). A total of 36 needle punctures were tested on a Kinect™ for Windows version 2 (Kinect™ V2). The target registration error (TRE), user error, and TPE are 4.26  ±  1.94 mm, 2.92  ±  1.67 mm, and 5.23  ±  2.29 mm, respectively. No statistically significant differences in TPE regarding operator’s skill and trajectory are observed. Additionally, a Kinect™ for Windows version 1 (Kinect™ V1) was tested with 12 insertions, and the TRE evaluated with the Kinect™ V1 is statistically significantly larger than that with the Kinect™ V2. For the animal experiment, fifteen artificial liver tumors were inserted guided by the navigation system. The TPE was evaluated as 6.40  ±  2.72 mm, and its lateral and longitudinal component were 4.30  ±  2.51 mm and 3.80  ±  3.11 mm, respectively. This study demonstrates that the navigation accuracy of the proposed system is acceptable

    Wang, Yongzhi; Braun, Oscar Ö; Zhang, Su; Norström, Eva; Thorlacius, Henrik


    Abdominal sepsis is associated with significant changes in systemic inflammation and coagulation. The purpose of the present study was to examine the role of peripheral blood monocytes for systemic coagulation, including thrombin generation and consumption of coagulation factors. Abdominal sepsis was induced by cecal ligation and puncture (CLP) in C57BL/6 mice. Plasma and lung levels of IL-6 and C-X-C motif (CXC) chemokines [chemokine CXC ligand (CXCL)1, CXCL2, and CXCL5], pulmonary activity of myeloperoxidase, thrombin generation, and coagulation factors were determined 6 h after CLP induction. Administration of clodronate liposomes decreased circulating levels of monocytes by 96%. Time to peak thrombin formation was increased and peak and total thrombin generation was decreased in plasma from CLP animals. Monocyte depletion decreased time to peak formation of thrombin and increased peak and total generation of thrombin in septic animals. In addition, monocyte depletion decreased the CLP-induced increase in the levels of thrombin-antithrombin complexes in plasma. Depletion of monocytes increased plasma levels of prothrombin, factor V, factor X, and protein C in septic mice. Moreover, depletion of monocytes decreased CLP-induced levels of IL-6 and CXC chemokines in the plasma and lung by >59% and 20%, respectively. CLP-induced myeloperoxidase activity in the lung was attenuated by 44% in animals depleted of monocytes. Taken together, our findings show, for the first time, that peripheral blood monocytes regulate systemic coagulation. The results of our study improve our understanding of the pathophysiology of sepsis and encourage further attempts to target innate immune cell functions in abdominal sepsis.

    Yan, Xiaopeng; Lv, Yi; Ma, Feng; Ma, Jia; Wang, Haohua; Wang, Shanpei; Li, Dichen; Liu, Yaxiong; Jia, Shenli; Shi, Zongqian; Luo, Ruixue


    A new system of blood flow block for control of bleeding in abdominal operation is composed of an abdominal magnetic blocking unit, an abdominal external electromagnet unit and other non-magnetic operation instrument. The abdominal external electromagnetic unit is placed in advance in the operation bed. The abdominal magnetic blocking unit can be placed directly on the ventral of the large vessels when need to blocking the abdominal large vessels during the operation. According to the non-contact suction characteristics of magnetic materials, the two magnetic units will attract each other and compression the vessels. Using this system for vascular occlusion does not need clear exposure and without separating vessel. There is the advantage of rapid, accurate and reliable for the system.

    Purpose: Abdominal compression is known to be effective but, often makes external-marker-based monitoring of breathing motion not feasible. In this study, we developed and evaluated a system that enables both abdominal compression and monitoring of residual abdominal motion simultaneously. The system can also provide visual-biofeedback capability. Methods: The system developed consists of a compression belt, an abdominal motion monitoring sensor (gas pressure sensor) and a visual biofeedback device. The compression belt was designed to be able to compress the frontal side of the abdomen. The pressure level of the belt is controlled by air volume and monitored in real time using the gas pressure sensor. The system displays not only the real-time monitoring curve but also a guiding respiration model (e.g., a breath hold or shallow breathing curve) simultaneously on the head mounted display to help patients keep their breathing pattern as consistent as possible. Three healthy volunteers were enrolled in this pilot study and respiratory signals (pressure variations) were obtained both with and without effective abdominal compression to investigate the feasibility of the developed system. Two guidance patterns, breath hold and shallow breathing, were tested. Results: All volunteers showed smaller abdominal motion with compression (about 40% amplitude reduction compared to without compression). However, the system was able to monitor residual abdominal motion for all volunteers. Even under abdominal compression, in addition, it was possible to make the subjects successfully follow the guide patterns using the visual biofeedback system. Conclusion: The developed abdominal compression & respiratory guiding system was feasible for residual abdominal motion management. It is considered that the system can be used for a respiratory motion involved radiation therapy while maintaining the merit of abdominal compression. This work was supported by the Radiation Technology R

    Background: Obstructive sleep apnea is strongly associated with obesity, particularly abdominal obesity common in centrally obese males.Previous studies have demonstrated that intra-abdominal pressure (IAP) is increased in morbid obesity, and tracheal traction forces may influence pharyngeal airway collapsibility.This study aimed to investigate that whether IAP plays a role in the mechanism of upper airway (UA) collapsibility via IAP-related caudal tracheal traction.Methods: An abdominal wall lifting (AWL) system and graded CO2 pneumoperitoneum pressure was applied to four supine, anesthetized Guizhou miniature pigs and its effects on tracheal displacement (TD) and airflow dynamics of UA were studied.Individual run data in 3 min obtained before and after AWL and obtained before and after graded pneumoperitoneum pressure were analyzed.Differences between baseline and AWL/graded pneumoperitoneum pressure data of each pig were examined using a Student's t-test or analysis of variance.Results: Application of AWL resulted in decreased IAP and significant caudal TD.The average displacement amplitude was 0.44 mm (P < 0.001).There were three subjects showed increased tidal volume (TV) (P < 0.0l) and peak inspiratory airflow (P < 0.01);however, the change of flow limitation inspiratory UA resistance (Rua) was not significant.Experimental increased IAP by pneumoperitoneum resulted in significant cranial TD.The average displacement amplitude was 1.07 mm (P < 0.001) when IAP was 25 cmH20 compared to baseline.There were three subjects showed reduced Rua while the TV increased (P < 0.01).There was one subject had decreased TV and elevated Rua (P < 0.001).Conclusions: Decreased IAP significantly increased caudal TD, and elevated IAP significantly increased cranial TD.However, the mechanism of UA collapsibility appears primarily mediated by changes in lung volume rather than tracheal traction effect.TV plays an independent role in the mechanism of UA collapsibility.

    Veliev, N A; Ismailov, V F


    In 26 patients in complex of treatment of abdominal sepsis there was applied a 1.5% solution of reamberin intravenously in 400 ml dose during 5 days. The results of treatment were estimated, studying indices of systemic inflammatory reaction (SIR) and hepatic tests. Reamberin application have promoted rapid normalization of the parameters studied. The authors consider, that efficacy of reamberin is caused not only by positive impact on the SIR course, but by hepatoprotective action of the preparation as well.

The target registration error (TRE), user error, and TPE are 4.26  ±  1.94 mm, 2.92  ±  1.67 mm, and 5.23  ±  2.29 mm, respectively. No statistically significant differences in TPE regarding operator's skill and trajectory are observed. Additionally, a Kinect(™) for Windows version 1 (Kinect(™) V1) was tested with 12 insertions, and the TRE evaluated with the Kinect(™) V1 is statistically significantly larger than that with the Kinect(™) V2. For the animal experiment, fifteen artificial liver tumors were inserted guided by the navigation system. The TPE was evaluated as 6.40  ±  2.72 mm, and its lateral and longitudinal component were 4.30  ±  2.51 mm and 3.80  ±  3.11 mm, respectively. This study demonstrates that the navigation accuracy of the proposed system is

    Full Text Available The primo-vascular system (PVS is a novel network identified in various animal tissues. However, the PVS in subcutaneous tissue has not been well identified. Here, we examined the putative PVS on the surface of abdominal subcutaneous tissue in rats. Hemacolor staining revealed dark blue threadlike structures consisting of nodes and vessels, which were frequently observed bundled with blood vessels. The structure was filled with various immune cells including mast cells and WBCs. In the structure, there were inner spaces (20–60 µm with low cellularity. Electron microscopy revealed a bundle structure and typical cytology common with the well-established organ surface PVS, which were different from those of the lymphatic vessel. Among several subcutaneous (sc PVS tissues identified on the rat abdominal space, the most outstanding was the scPVS aligned along the ventral midline. The distribution pattern of nodes and vessels in the scPVS closely resembled that of the conception vessel meridian and its acupoints. In conclusion, our results newly revealed that the PVS is present in the abdominal subcutaneous tissue layer and indicate that the scPVS tissues are closely correlated with acupuncture meridians. Our findings will help to characterize the PVS in the other superficial tissues and its physiological roles.

    Basing on data of analysis of the hemostasis system state in the patients, suffering abdominal aorta aneurysm, a tendency for raising of postoperative soluble fibrin and D-dimer content in the blood plasm and reduction of these indices on the third day was noted. The abovementioned markers content depends on the aneurysm size, the fibrin deposits presence, the terms from clinical signs beginning to the certain therapy administration and anticoagulants application. Information about correlation between content of D-dimer and soluble fibrin in the treatment dynamics is important for determination of activation degree in the patients blood coagulation system and the thrombotic complications prognosis.

  5. In vitro pressure manifolding distribution evaluation of ABThera™ Active Abdominal Therapy System, V.A.C.® Abdominal Dressing System, and Barker’s vacuum packing technique conducted under dynamic conditions

    Directory of Open Access Journals (Sweden)

    Angel Delgado


    Full Text Available Objectives: Temporary abdominal closure methods allow for management of open abdomens where immediate primary closure is not possible and/or where repeat abdominal entries are necessary. We assessed pressure mapping and fluid extraction efficiency of three open abdomen dressing systems: ABThera™ Active Abdominal Therapy System, V.A.C.® Abdominal Dressing System, and Barker’s vacuum packing technique. Methods: An in vitro test model was designed to simulate physical conditions present in an open abdomen. The model consisted of a rigid rest platform with elevated central region and a flexible outer layer with centrally located incision. Constant −125 mmHg negative pressure was applied according to the type of system, under simulated dynamic conditions, using albumin-based solution with a viscosity of 14 cP. Data were collected by pressure sensors located circumferentially into three concentric zones: Zone 1 (closest to negative pressure source, Zone 2 (immediately outside of manifolding material edge, and Zone 3 (area most distal from negative pressure source. Each value was the result of approximately 100 pressure readings/zone/experiment with a total of three experiments for each system. Results: Pressure distribution of ABThera Therapy was significantly (p < 0.05 superior to Barker’s vacuum packing technique in all three evaluated zones. Similarly, V.A.C. Abdominal Dressing System pressure distribution was significantly (p < 0.05 improved compared to Barker’s vacuum packing technique in all zones. There were no pressure distribution differences in Zone 1 between ABThera Therapy and V.A.C. Abdominal Dressing System; however, in Zones 2 and 3, ABThera Therapy was significantly (p < 0.05 superior to V.A.C. Abdominal Dressing System. Conclusions: These data suggest that all approaches to negative pressure therapy for open abdomen treatment are not equal. Additional research should be conducted to elucidate clinical

  6. Role of the endocannabinoid system in abdominal obesity and the implications for cardiovascular risk. (United States)

    Rosenson, Robert S


    Several cardiometabolic factors present in obese and insulin-resistant individuals represent a continuum of increasing risk for the development of type 2 diabetes and cardiovascular disease. The importance of abdominal obesity as an independent risk factor is underscored by its association with adverse endocrine function. Recent evidence from animal and human studies has shown a role for the endocannabinoid system in maintaining energy balance and glucose and lipoprotein metabolism, with overactivity linked to aberrant glycemic and lipoprotein control, and a link to adiposity. Modulation of this system through endocannabinoid-receptor blockade has resulted in an improvement in a number of important risk factors in clinical trials, including visceral and subcutaneous abdominal adipose tissue, glucose tolerance, dyslipidemia and measures of inflammation. These findings may have significant implications for the management of patients at risk of developing cardiovascular and metabolic disease; however, the occurrence of psychiatric adverse events with rimonabant may preclude further development of centrally active endocannabinoid receptor antagonists for the treatment of cardiometabolic disorders. Future research is needed to explore the role of selective peripheral CB(1) receptor antagonists in the treatment of patients at high cardiometabolic risk.

    Martinelli, Thomas; Bressollette, Luc; Pelissier, Franck; Boidard, Eric; Troccaz, Jocelyne; Cinquin, Philippe


    OBJECTIVE: The TER system is a robot-based tele-echography system allowing remote ultrasound examination. The specialist moves a mock-up of the ultrasound probe at the master site, and the robot reproduces the movements of the real probe, which sends back ultrasound images and force feedback. This tool could be used to perform ultrasound examinations in small health care centers or from isolated sites. The objective of this study was to prove, under real conditions, the feasibility and reliability of the TER system in detecting abdominal aortic and iliac aneurysms. METHODS: Fifty-eight patients were included in 2 centers in Brest and Grenoble, France. The remote examination was compared with the reference standard, the bedside examination, for aorta and iliac artery diameter measurement, detection and description of aneurysms, detection of atheromatosis, the duration of the examination, and acceptability. RESULTS: All aneurysms (8) were detected by both techniques as intramural thrombosis and extension to the...

This study is designed to provide a new scoring system for a better diagno- sis of IAI after blunt trauma. Methods: This prospective observational study was performed from April 2011 to October 2012 on patients aged above 18 years and suspected with blunt abdominal trauma (BAT admitted to the emergency department (ED of Imam Hussein Hospital and Shohadaye Hafte Tir Hospital. All patients were assessed and treated based on Advanced Trauma Life Support and ED protocol. Diagnosis was done according to CT scan findings, which was considered as the gold standard. Data were gathered based on patient's history, physical exam, ultrasound and CT scan findings by a general practitioner who was not blind to this study. Chisquare test and logistic regression were done. Factors with significant relationship with CT scan were imported in multivariate regression models, where a coefficient (β was given based on the contribution of each of them. Scoring system was developed based on the obtained total βof each factor. Results: Altogether 261 patients (80.1% male were enrolled (48 cases of IAI. A 24-point blunt abdominal trauma scoring system (BATSS was developed. Patients were divided into three groups including low (score<8, moderate (8≤score<12 and high risk (score≥12. In high risk group immediate laparotomy should be done, moderate group needs further assessments, and low risk group should be kept under observation. Low risk patients did not show positive CT-scans (specificity 100%. Conversely, all high risk patients had positive CT-scan findings (sensitivity 100%. The receiver operating characteristic curve indicated a close relationship between the results of CT scan and BATSS (sensitivity=99.3%. Conclusion: The present scoring system furnishes a

  11. Diagnosis and typing of systemic amyloidosis: The role of abdominal fat pad fine needle aspiration biopsy

    Directory of Open Access Journals (Sweden)

    Halloush Ruba


    Full Text Available Introduction: Systemic amyloidosis (SA has a broad nonspecific clinical presentation. Its diagnosis depends on identifying amyloid in tissues. Abdominal fat pad fine needle aspiration (FPFNA has been suggested as a sensitive and specific test for diagnosing SA. Materials and Methods: Thirty-nine FPFNA from 38 patients (16 women and 20 men, age range 40-88 years during a 15-year period were reviewed. Smears and cell blocks were stained with Congo red (CR. A panel of antibodies (serum amyloid protein, serum amyloid A, albumin, transthyretin, kappa light chain and lambda light chain was used on six cell blocks from five patients. The FNA findings were correlated with clinical and histological follow-up. Results: FPFNAs were positive, confirmed by CR in 5/39 (13%, suspicious in 1/39 (3%, negative in 28/39 (72%, and insufficient for diagnosis in 5/39 (13% of cases. In all the positive cases, SA was confirmed within 2-16 weeks. Among the 28 negative cases, SA was diagnosed in 21, the rest were lost to follow-up. Among the insufficient cases, SA was diagnosed in four and one was lost to follow-up. Specificity was 100%, whereas sensitivity was 19%. SA typing using cell block sections was successful in three, un-interpretable in one, and negative in two cases. Conclusion: FPFNA for SA is not as good as previously reported. This may be due to different practice setting, level of experience, diagnostic technique, or absence of abdominal soft tissue involvement. A negative result of FPFNA does not exclude SA. Immune phenotyping of amyloid is possible on cell block.

    Blüher, Matthias; Engeli, Stefan; Klöting, Nora; Berndt, Janin; Fasshauer, Mathias; Bátkai, Sándor; Pacher, Pál; Schön, Michael R; Jordan, Jens; Stumvoll, Michael


    The endocannabinoid system has been suspected to contribute to the association of visceral fat accumulation with metabolic diseases. We determined whether circulating endocannabinoids are related to visceral adipose tissue mass in lean, subcutaneous obese, and visceral obese subjects (10 men and 10 women in each group). We further measured expression of the cannabinoid type 1 (CB(1)) receptor and fatty acid amide hydrolase (FAAH) genes in paired samples of subcutaneous and visceral adipose tissue in all 60 subjects. Circulating 2-arachidonoyl glycerol (2-AG) was significantly correlated with body fat (r = 0.45, P = 0.03), visceral fat mass (r = 0.44, P = 0.003), and fasting plasma insulin concentrations (r = 0.41, P = 0.001) but negatively correlated to glucose infusion rate during clamp (r = 0.39, P = 0.009). In visceral adipose tissue, CB(1) mRNA expression was negatively correlated with visceral fat mass (r = 0.32, P = 0.01), fasting insulin (r = 0.48, P endocannabinoid system in human obesity. Thus, the endocannabinoid system may represent a primary target for the treatment of abdominal obesity and associated metabolic changes.

  13. Extraction of fetal electrocardiogram (ECG) by extended state Kalman filtering and adaptive neuro-fuzzy inference system (ANFIS) based on single channel abdominal recording

    Indian Academy of Sciences (India)

    D Panigrahy; P K Sahu


    Fetal electrocardiogram (ECG) gives information about the health status of fetus and so, an early diagnosis of any cardiac defect before delivery increases the effectiveness of appropriate treatment. In this paper, authors investigate the use of adaptive neuro-fuzzy inference system (ANFIS) with extended Kalman filter for fetal ECG extraction from one ECG signal recorded at the abdominal areas of the mother’s skin. The abdominal ECG is considered to be composite as it contains both mother’s and fetus’ ECG signals. We use extended Kalman filter framework to estimate the maternal component from abdominal ECG. The maternal component in the abdominal ECG signal is a nonlinear transformed version of maternal ECG. ANFIS network has been used to identify this nonlinear relationship, and to align the estimated maternal ECG signal with the maternal component in the abdominal ECG signal. Thus, we extract the fetal ECG component by subtracting the aligned version of the estimated maternal ECG from the abdominal signal. Our results demonstrate the effectiveness of the proposed technique in extracting the fetal ECG component from abdominal signal at different noise levels. The proposed technique is also validated on the extraction of fetal ECG from both actual abdominal recordings and synthetic abdominal recording.

  14. Indwelling intrathecal catheter with subcutaneous abdominal reservoir: a viable baclofen delivery system in severely cachectic patients. (United States)

    Waqar, Mueez; Ellenbogen, Jonathan R; Kumar, Ram; Sneade, Christine; Zebian, Bassel; Williams, Dawn; Pettorini, Benedetta L


    Intrathecal baclofen (ITB) is a reversible treatment that reduces muscle tone to ameliorate spasticity and dystonia in patients with cerebral palsy (CP). The resulting decrease in energy expenditure allows patients to gain much-needed weight, albeit temporarily. Modern techniques require sufficient abdominal musculature and subcutaneous fat to permit the implantation of an indwelling pump. In patients with extremely low muscle bulk, visceral pumps may be impractical or impossible, with increased risks of dehiscence and infection. The authors describe a variation of the classical procedure in a young patient with severe cachexia. A 10-year-old boy with spastic-dystonic quadriplegic CP was admitted to the neuromedical unit. Numerous drug trials had failed, and surgical intervention was deemed necessary but was complicated by his cachectic body habitus. The authors inserted a lumbar intrathecal catheter and subcutaneously tunneled it to the anterolateral abdomen, where it was connected to a subcutaneous injection port. Baclofen was continuously infused into the subcutaneous port using a noncoring needle connected to an external pump. The needle and line were changed every 5 days to minimize the risk of sepsis. Although other techniques, such as intraventricular baclofen delivery, have been described, these are largely dependent upon sufficient musculature to support a visceral pump. A subcutaneous injection port system represents an alternative approach that reduces the risk of sepsis and may be better tolerated in cachectic patients.

  16. Abdominal actinomycosis. (United States)

    Wagenlehner, F M E; Mohren, B; Naber, K G; Männl, H F K


    Intra-abdominal and extraperitoneal actinomycosis are rare infections, caused by different Actinomyces species. However, they have been diagnosed more frequently in the last ten years. We report three cases of abdominal actinomycosis and a literature review of the last eight years. All three patients were diagnosed by means of histopathologic examination only. In one case, an intrauterine device (IUD) was associated with the infection. Therapy consisted of surgical resection of the inflammatory, infected tissue, and long-term antibiotic therapy. All patients are free of recurrence. Abdominal actinomycosis should be included in the differential diagnosis of an abdominal pathology of insidious onset, especially when an IUD is in place. Even when infection had spread extensively, combined operative and antibiotic therapy cured most of the cases.

  17. A prospective, controlled evaluation of the abdominal reapproximation anchor abdominal wall closure system in combination with VAC therapy compared with VAC alone in the management of an open abdomen. (United States)

    Long, Kristin L; Hamilton, David A; Davenport, Daniel L; Bernard, Andrew C; Kearney, Paul A; Chang, Phillip K


    Dramatic increases in damage control and decompressive laparotomies and a significant increase in patients with open abdominal cavities have resulted in numerous techniques to facilitate fascial closure. We hypothesized addition of the abdominal reapproximation anchor system (ABRA) to the KCI Abdominal Wound Vac™ (VAC) or KCI ABThera™ would increase successful primary closure rates and reduce operative costs. Fourteen patients with open abdomens were prospectively randomized into a control group using VAC alone (control) or a study group using VAC plus ABRA (VAC-ABRA). All patients underwent regular VAC changes; patients receiving VAC-ABRA also underwent concomitant daily elastomer adjustment of the ABRA system. Primary end points included abdominal closure, number of operating room (OR) visits, and OR time use. Eight patients were included in the VAC-ABRA group and six patients in the control group. Primary closure rates between groups were not statistically different; however, the number of trips to the OR and OR time use were different. Despite higher Acute Physiology and Chronic Health Evaluation II scores, larger starting wound size, and higher rates of abdominal compartment syndrome, closure rates in the VAC-ABRA group were similar to VAC alone. Importantly, however, fewer OR trips and less OR time were required for the VAC-ABRA group.

  19. Endovascular treatment of abdominal aortic aneurysms--6 years of experience with Ella stent-graft system

    Energy Technology Data Exchange (ETDEWEB)

    Koecher, Martin E-mail:; Utikal, Petr; Koutna, Jirina; Bachleda, Petr; Buriankova, Eva; Herman, Miroslav; Bucil, Jiri; Benysek, Vladimir; Cerna, Marie; Kojecky, Zdenek


    Purpose: Evaluation of 6-year results of abdominal aortic aneurysm (AAA) treatment by Ella stent-grafts with regard to safety and effectivity in relation to morphology of the aneurysm. Methods: From a group of 172 patients with AAA, in whom elective endovascular treatment was considered, 120 of them (69.8%) were found to be suitable for this type of therapy. The bifurcated type of stent-graft was implanted in 97 patients, uniiliacal type in 19 patients and only four patients were found to be suitable for tubular type of stent-graft. Additional necessary procedures (internal iliac artery occlusion or contralateral common iliac artery occlusion in a group of patients with uniiliacal type of stent-graft) were performed surgically during the stent-graft implantation. CT and US controls were performed at 3, 6 and 12 months after implantation, later every 12 months. Results: Primary technical success was achieved in 109 of the 120 patients (91%). Primary endoleak was recorded in 11 patients (primary endoleak type Ia in seven patients, type Ib in three patients and type IIIa in one patient). Assisted technical success after reintervention or spontaneous seal was 98.3%. Surgical conversion was indicated in two patients (1.7%). Perioperative mortality rate was 3.3%. Total average follow-up period was 20.7 months (range from 2 to 60 months). In nine patients (7.5%) secondary endoleak type II was found at control CT or US, in three patients partial thrombosis of the stent-graft was found. There was no aneurysm rupture during follow-up. Conclusion: Treatment of AAA with Ella stent-graft system is effective and safe. Bifurcated stent-graft is the most frequently used type. Uniiliacal type of stent-graft is used by us only in cases of complicated morphology.

  20. Abdominal Sepsis. (United States)

    De Waele, Jan J


    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.

  1. Texture-learning-based system for three-dimensional segmentation of renal parenchyma in abdominal CT images (United States)

    Peng, Cong-Qi; Chang, Yuan-Hsiang; Wang, Li-Jen; Wong, Yon-Choeng; Chiang, Yang-Jen; Jiang, Yan-Yau


    Abdominal CT images are commonly used for the diagnosis of kidney diseases. With the advances of CT technology, processing of CT images has become a challenging task mainly because of the large number of CT images being studied. This paper presents a texture-learning based system for the three-dimensional (3D) segmentation of renal parenchyma in abdominal CT images. The system is designed to automatically delineate renal parenchyma and is based on the texturelearning and the region-homogeneity-based approaches. The first approach is achieved with the texture analysis using the gray-level co-occurrence matrix (GLCM) features and an artificial neural network (ANN) to determine if a pixel in the CT image is likely to fall within the renal parenchyma. The second approach incorporates a two-dimensional (2D) region growing to segment renal parenchyma in single CT image slice and a 3D region growing to propagate the segmentation results to neighboring CT image slices. The criterion for the region growing is a test of region-homogeneity which is defined by examining the ANN outputs. In system evaluation, 10 abdominal CT image sets were used. Automatic segmentation results were compared with manually segmentation results using the Dice similarity coefficient. Among the 10 CT image sets, our system has achieved an average Dice similarity coefficient of 0.87 that clearly shows a high correlation between the two segmentation results. Ultimately, our system could be incorporated in applications for the delineation of renal parenchyma or as a preprocessing in a CAD system of kidney diseases.

  2. A levonorgestrel-releasing intrauterine system embedded in the omentum in a woman with abdominal pain: a case report

    Directory of Open Access Journals (Sweden)

    Phillips Kevin


    Full Text Available Abstract Introduction The Mirena intrauterine system has been licensed as a contraceptive in the United Kingdom since May 1995. The use of an intrauterine system as a primary method of contraception among women has been slowly increasing over the last few years and they now account for about 3% of contraceptive use in England. The Mirena intrauterine system now also has a license for the management of idiopathic menorrhagia. Women may be informed that the rate of uterine perforation associated with intrauterine contraceptive use is low (0-2.3 per 1000 insertions. The rate of perforation reported with the Mirena intrauterine system in a large observational cohort study was 0.9 per 1000 insertions. Case presentation In this case report, the diagnosis of an intraperitoneal Mirena intrauterine system was noted nearly four years after its insertion, despite the patient having had a vaginal hysterectomy and admissions to hospital in the interim with complaints of abdominal pain. Conclusion This case report demonstrates clearly that whenever there is a question of a intrauterine system having fallen out following an ultrasound scan report showing an empty uterus, clinicians should also perform an abdominal X-ray.

  4. Lysophosphatidic acid receptor 1 antagonist ki16425 blunts abdominal and systemic inflammation in a mouse model of peritoneal sepsis. (United States)

    Zhao, Jing; Wei, Jianxin; Weathington, Nathaniel; Jacko, Anastasia M; Huang, Hai; Tsung, Allan; Zhao, Yutong


    Lysophosphatidic acid (LPA) is a bioactive lipid mediator of inflammation via the LPA receptors 1-6. We and others have previously described proinflammatory and profibrotic activities of LPA signaling in bleomycin- or lipopolysaccharide (LPS)-induced pulmonary fibrosis or lung injury models. In this study, we investigated if LPA signaling plays a role in the pathogenesis of systemic sepsis from an abdominal source. We report here that antagonism of the LPA receptor LPA1 with the small molecule ki16425 reduces the severity of abdominal inflammation and organ damage in the setting of peritoneal endotoxin exposure. Pretreatment of mice with intraperitoneal ki16425 eliminates LPS-induced peritoneal neutrophil chemokine and cytokine production, liver oxidative stress, liver injury, and cellular apoptosis in visceral organs. Mice pretreated with ki16425 are also protected from LPS-induced mortality. Tissue myeloperoxidase activity is not affected by LPA1 antagonism. We have shown that LPA1 is associated with LPS coreceptor CD14 and the association is suppressed by ki16425. LPS-induced phosphorylation of protein kinase C δ (PKCδ) and p38 mitogen-activated protein kinase (p38 MAPK) in liver cells and interleukin 6 production in Raw264 cells are likewise blunted by LPA1 antagonism. These studies indicate that the small molecule inhibitor of LPA1, ki16425, suppresses cytokine responses and inflammation in a peritoneal sepsis model by blunting downstream signaling through the LPA1-CD14-toll-like receptor 4 receptor complex. This anti-inflammatory effect may represent a therapeutic strategy for the treatment of systemic inflammatory responses to infection of the abdominal cavity.

  7. Development and evaluation of a novel, real time mobile telesonography system in management of patients with abdominal trauma: study protocol (United States)


    Background Despite the use of e-FAST in management of patients with abdominal trauma, its utility in prehospital setting is not widely adopted. The goal of this study is to develop a novel portable telesonography (TS) system and evaluate the comparability of the quality of images obtained via this system among healthy volunteers who undergo e-FAST abdominal examination in a moving ambulance and at the ED. We hypothesize that: (1) real-time ultrasound images of acute trauma patients in the pre-hospital setting can be obtained and transmitted to the ED via the novel TS system; and (2) Ultrasound images transmitted to the hospital from the real-time TS system will be comparable in quality to those obtained in the ED.

    Full Text Available Abstract Background Despite the use of e-FAST in management of patients with abdominal trauma, its utility in prehospital setting is not widely adopted. The goal of this study is to develop a novel portable telesonography (TS system and evaluate the comparability of the quality of images obtained via this system among healthy volunteers who undergo e-FAST abdominal examination in a moving ambulance and at the ED. We hypothesize that: (1 real-time ultrasound images of acute trauma patients in the pre-hospital setting can be obtained and transmitted to the ED via the novel TS system; and (2 Ultrasound images transmitted to the hospital from the real-time TS system will be comparable in quality to those obtained in the ED. Methods Study participants are three healthy volunteers (one each with normal, overweight and obese BMI category. The ultrasound images will be obtained by two ultrasound-trained physicians The TS is a portable sonogram (by Sonosite interfaced with a portable broadcast unit (by Live-U.

  9. Nuclear factor of activated T cells regulates neutrophil recruitment, systemic inflammation, and T-cell dysfunction in abdominal sepsis. (United States)

    Zhang, Su; Luo, Lingtao; Wang, Yongzhi; Gomez, Maria F; Thorlacius, Henrik


    The signaling mechanisms regulating neutrophil recruitment, systemic inflammation, and T-cell dysfunction in polymicrobial sepsis are not clear. This study explored the potential involvement of the calcium/calcineurin-dependent transcription factor, nuclear factor of activated T cells (NFAT), in abdominal sepsis. Cecal ligation and puncture (CLP) triggered NFAT-dependent transcriptional activity in the lung, spleen, liver, and aorta in NFAT-luciferase reporter mice. Treatment with the NFAT inhibitor A-285222 prior to CLP completely prevented sepsis-induced NFAT activation in all these organs. Inhibition of NFAT activity reduced sepsis-induced formation of CXCL1, CXCL2, and CXCL5 chemokines and edema as well as neutrophil infiltration in the lung. Notably, NFAT inhibition efficiently reduced the CLP-evoked increases in HMBG1, interleukin 6 (IL-6), and CXCL5 levels in plasma. Moreover, administration of A-285222 restored sepsis-induced T-cell dysfunction, as evidenced by markedly decreased apoptosis and restored proliferative capacity of CD4 T cells. Along these lines, treatment with A-285222 restored gamma interferon (IFN-γ) and IL-4 levels in the spleen, which were markedly reduced in septic mice. CLP-induced formation of regulatory T cells (CD4(+) CD25(+) Foxp3(+)) in the spleen was also abolished in A-285222-treated animals. All together, these novel findings suggest that NFAT is a powerful regulator of pathological inflammation and T-cell immune dysfunction in abdominal sepsis. Thus, our data suggest that NFAT signaling might be a useful target to protect against respiratory failure and immunosuppression in patients with sepsis.

    increasing, and severity is determined by injury to vital structures in the abdomen and associated injuries. AIM: To identify the causes of abdominal trauma, the most frequently injured digestive viscera, the presence of injuries in other anatomic regions and the relationship of abdominal trauma to sex and age group. METHOD: Thirty-four patients from the Sistema Único de Saúde [the public healthcare system] were selected, all diagnosed with abdominal trauma and seen from January 2005 through September 2005 at the Hospital Universitário Evangélico de Curitiba. Data collection was performed with the aid of a previously formulated protocol. RESULTS: It was found that 91% of the victims were males. The most affected age group was in its third decade of life. Regarding the classification of traumatic injuries, 58.82% presented with open trauma wounds and 41.18% with contusions. Falls accounted for 44 % of contusions, followed by traffic accidents with 35%. The most common open wounds were caused by firearms in 56% of cases and by knives in 44%. Small intestine injury occurred in 31% of the open wounds, followed by liver, colon and kidney injury, with 23% each. In contusions, 60% of the patients sustained spleen injuries. The thorax was the region most frequently associated with abdominal trauma (31%. CONCLUSION: The leading causes of abdominal trauma were gunshot wounds (penetrating trauma and falls (blunt trauma. The most frequently injured viscera in blunt trauma were the parenchymatous ones (spleen and liver, and intestines, liver and kidneys in penetrating trauma. Most patients were males, predominantly in their third decade of life.

  13. Penetration-enhancing effect of ethanol-water solvent system and ethanolic solution of carvone on transdermal permeability of nimodipine from HPMC gel across rat abdominal skin. (United States)

    Krishnaiah, Y S R; Bhaskar, P; Satyanarayana, V


    The aim of this investigation was to find the effect of the ethanol-water solvent system and the ethanolic solution of carvone on the permeation of nimodipine across rat abdominal skin in order to select a suitable solvent system and optimal concentration of carvone for the development of membrane-moderated transdermal therapeutic system of nimodipine. The solubility of nimodipine in water, ethanol, and ethanol-water cosolvent systems, or the selected concentration of carvone [2% (w/w) to 12% (w/w)] in 60:40 (v/v) ethanol-water were determined. The effect of these solvents or cosolvent systems on the transdermal permeation of nimodipine was also studied using in vitro permeability studies across the rat abdominal skin. The co-solvent system containing 60:40 (v/v) of ethanol-water showed highest permeability across the rat abdominal skin. Further, the effect of ethanolic solution [60% (v/v) ethanol-water] of carvone [2% (w/w) to 12% (w/w)] on the in vitro permeation of nimodipine across the rat abdominal skin from 2% (w/w) hydroxypropyl methylcellulose (HPMC) gel was also investigated. The transdermal permeability of nimodipine across rat abdominal skin was enhanced further by the addition of carvone to HPMC gel prepared with 60% (v/v) of ethanol. There was a steady effect on the flux of nimodipine (161.02 +/- 4.14 microg/cm2/hr) with an enhancement ratio of 4.56 when carvone was incorporated at a concentration of 10% (w/w) in HPMC gels prepared with 60% (v/v) ethanol. The Fourier transform infrared data indicated that ethanolic solution of carvone increased the transdermal permeability of nimodipine across the rat abdominal skin by partial extraction of lipids in the stratum corneum. The results suggest that 10% (w/w) of carvone in 60% (v/v) ethanol-water, along with HPMC as antinucleating agent may be useful for enhancing the skin permeability of nimodipine from the membrane-moderated transdermal therapeutic system.

  1. From tissue iron retention to low systemic haemoglobin levels, new pathophysiological biomarkers of human abdominal aortic aneurysm. (United States)

    Martinez-Pinna, R; Lindholt, J S; Madrigal-Matute, J; Blanco-Colio, L M; Esteban-Salan, M; Torres-Fonseca, M M; Lefebvre, T; Delbosc, S; Laustsen, J; Driss, F; Vega de Ceniga, M; Gouya, L; Weiss, G; Egido, J; Meilhac, O; Michel, J-B; Martin-Ventura, J


    Iron deposits are observed in tissue of abdominal aortic aneurysm (AAA) patients, although the underlying mechanisms are not completely elucidated. Therefore we explored circulating markers of iron metabolism in AAA patients, and tested if they could serve as biomarkers of AAA. Increased red blood cell (RBC)-borne iron retention and transferrin, transferrin receptor and ferritin expression was observed in AAA tissue compared to control aorta (immunohistochemistry and western blot). In contrast, decreased circulating iron, transferrin, mean corpuscular haemoglobin concentration (MCHC) and haemoglobin concentration, along with circulating RBC count, were observed in AAA patients (aortic diameter >3 cm, n=114) compared to controls (aortic diameter aortic diameter in AAA patients. The association of low haemoglobin with AAA presence or aortic diameter was independent of specific risk factors. Moreover, MCHC negatively correlated with thrombus area in another cohort of AAA patients (aortic diameter 3-5 cm, n=357). We found that anaemia was significantly more prevalent in AAA patients (aortic diameter >5 cm, n=8,912) compared to those in patients with atherosclerotic aorto-iliac occlusive disease (n=17,737) [adjusted odds ratio=1.77 (95% confidence interval: 1.61;1.93)]. Finally, the mortality risk among AAA patients with anaemia was increased by almost 30% [adjusted hazard ratio: 1.29 (95% confidence interval: 1.16;1.44)] as compared to AAA subjects without anaemia. In conclusion, local iron retention and altered iron recycling associated to high hepcidin and low transferrin systemic concentrations could lead to reduced circulating haemoglobin levels in AAA patients. Low haemoglobin levels are independently associated to AAA presence and clinical outcome.

  4. Abdominal epilepsy in chronic recurrent abdominal pain

    Directory of Open Access Journals (Sweden)

    V Y Kshirsagar


    Full Text Available Background: Abdominal epilepsy (AE is an uncommon cause for chronic recurrent abdominal pain in children and adults. It is characterized by paroxysmal episode of abdominal pain, diverse abdominal complaints, definite electroencephalogram (EEG abnormalities and favorable response to the introduction of anti-epileptic drugs (AED. We studied 150 children with chronic recurrent abdominal pain and after exclusion of more common etiologies for the presenting complaints; workup proceeded with an EEG. We found 111 (74% children with an abnormal EEG and 39 (26% children with normal EEG. All children were subjected to AED (Oxcarbazepine and 139 (92% children responded to AED out of which 111 (74% children had an abnormal EEG and 27 (18% had a normal EEG. On further follow-up the patients were symptom free, which helped us to confirm the clinical diagnosis. Context: Recurrent chronic abdominal pain is a common problem encountered by pediatricians. Variety of investigations are done to come to a diagnosis but a cause is rarely found. In such children diagnosis of AE should be considered and an EEG will confirm the diagnosis and treated with AED. Aims: To find the incidence of AE in children presenting with chronic recurrent abdominal pain and to correlate EEG findings and their clinical response to empirical AEDs in both cases and control. Settings and Design: Krishna Institute of Medical Sciences University, Karad, Maharashtra, India. Prospective analytical study. Materials and Methods: A total of 150 children with chronic recurrent abdominal pain were studied by investigations to rule out common causes of abdominal pain and an EEG. All children were then started with AED oxycarbamezepine and their response to the treatment was noted. Results: 111 (74% of the total 150 children showed a positive EEG change suggestive of epileptogenic activity and of which 75 (67.56% were females and 36 (32.43% were male, majority of children were in the age of group of 9

    Afonin, B V; Noskov, V B; Nichiporuk, I A; Sedova, E A; Goncharova, N P


    Ultrasonic investigations of the abdominal organs and splanchnic veins were performed in essentially healthy subjects tilted at 12 degrees and 15 degrees for the period of 12 hrs. and 24 hrs. Tilting produced typical redistribution of venous blood and body liquids toward the cranial end. In its turn, blood redistribution caused excessive venous plethora and abdominal stasis. These were succeeded by expansion of large veins in the abdomen, enlargement of parenchymal organs and contraction of their echogenicity, and thickening of the hollow organs walls. Changes in the gastrointestinal functions before meal included elevated gastric, hepatic and pancreatic secretion, and an increased amount of intestinal content. The investigations demonstrated that stasis of the splanchnic veins altered functioning of the digestive organs in tilted human subjects.

  6. Abdominal Decompression in Children

    Directory of Open Access Journals (Sweden)

    J. Chiaka Ejike


    Full Text Available Abdominal compartment syndrome (ACS increases the risk for mortality in critically ill children. It occurs in association with a wide variety of medical and surgical diagnoses. Management of ACS involves recognizing the development of intra-abdominal hypertension (IAH by intra-abdominal pressure (IAP monitoring, treating the underlying cause, and preventing progression to ACS by lowering IAP. When ACS is already present, supporting dysfunctional organs and decreasing IAP to prevent new organ involvement become an additional focus of therapy. Medical management strategies to achieve these goals should be employed but when medical management fails, timely abdominal decompression is essential to reduce the risk of mortality. A literature review was performed to understand the role and outcomes of abdominal decompression among children with ACS. Abdominal decompression appears to have a positive effect on patient survival. However, prospective randomized studies are needed to fully understand the indications and impact of these therapies on survival in children.

    Bonfante Ramírez, E; Bolaños Ancona, R; Simón Pereyra, L; Juárez García, L; García-Benitez, C Q


    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.

  14. Use of a web-based image reporting and tracking system for assessing abdominal imaging examination quality issues in a single practice. (United States)

    Rosenkrantz, Andrew B; Johnson, Evan; Sanger, Joseph J


    This article presents our local experience in the implementation of a real-time web-based system for reporting and tracking quality issues relating to abdominal imaging examinations. This system allows radiologists to electronically submit examination quality issues during clinical readouts. The submitted information is e-mailed to a designate for the given modality for further follow-up; the designate may subsequently enter text describing their response or action taken, which is e-mailed back to the radiologist. Review of 558 entries over a 6-year period demonstrated documentation of a broad range of examination quality issues, including specific issues relating to protocol deviation, post-processing errors, positioning errors, artifacts, and IT concerns. The most common issues varied among US, CT, MRI, radiography, and fluoroscopy. In addition, the most common issues resulting in a patient recall for repeat imaging (generally related to protocol deviation in MRI and US) were identified. In addition to submitting quality problems, radiologists also commonly used the tool to provide recognition of a well-performed examination. An electronic log of actions taken in response to radiologists' submissions indicated that both positive and negative feedback were commonly communicated to the performing technologist. Information generated using the tool can be used to guide subsequent quality improvement initiatives within a practice, including continued protocol standardization as well as education of technologists in the optimization of abdominal imaging examinations.

  15. [Inflammatory abdominal aortic aneurysm]. (United States)

    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

    Upadhyaya, P; Karak, A K; Sinha, A K; Kumar, B; Karki, S; Agarwal, C S


    Endometriosis of abdominal wall scar following operation on uterus and tubes is extremely rare. The late onset of symptoms after surgery is the usual cause of misdiagnosis. Scar endometriosis is a rare disease which is difficult to diagnose and should always be considered as a differential diagnosis of painful abdominal masses in women. The diagnosis is made only after excision and histopathology of the lesion. Preoperative differentials include hernia, lipoma, suture granuloma or abscess. Hence an awareness of the entity avoids delay in diagnosis, helps clinicians to a more tailored treatment and also avoids unnecessary referrals. We report a case of abdominal endometriosis. The definitive diagnosis of which was established by histopathological studies.

    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.

  20. [The abdominal catastrophe]. (United States)

    Seiler, Christian A


    Patients with an abdominal catastrophe are in urgent need of early, interdisciplinary medical help. The treatment plan should be based on medical priorities and clear leadership. First priority should be given to achieve optimal oxygenation of blood and stabilization of circulation during all treatment-phases. The sicker the patient, the less invasive the (surgical) treatment should to be, which means "damage control only". This short article describes 7 important, pragmatic rules that will help to increase the survival of a patient with an abdominal catastrophe. Preexisting morbidity and risk factors must be included in the overall risk-evaluation for every therapeutic intervention. The challenge in patients with an abdominal catastrophe is to carefully balance the therapeutic stress and the existing resistance of the individual patient. The best way to avoid abdominal disaster, however, is its prevention.

The system, alike others, includes not only determination of the inflammation factors and indices of endotoxicosis, but as well as those, concerning intraabdominal pressure, the anterior abdominal wall rigidity and the tissues elasticity. Among the important indices, needed to determine, were considered those, which categorize the syndrome of intraabdominal, intrathoracic and microregional hypertension as well as the mechanisms of endotoxicosis pathogenesis. The authors recommend to use the indices of pathological consequences of this two factors while doing assessment of the abdominal sepsis severity.

    Kuehn, Jens-Peter; Langner, Soenke; Hegenscheid, Katrin; Hosten, Norbert; Puls, Ralf [Ernst Moritz Arndt University of Greifswald, Department of Radiology, Greifswald (Germany); Evert, Matthias [Ernst Moritz Arndt University of Greifswald, Department of Pathology, Greifswald (Germany); Kickhefel, Antje [Siemens Healthcare, Erlangen (Germany)


    To investigate the feasibility and handling of abdominal MRI-guided biopsies in a 3-T MRI system. Over a 1-year period, 50 biopsies were obtained in 47 patients with tumours of the upper abdominal organs guided by 3-T MRI with a large-bore diameter of 70 cm. Lesions in liver (47), spleen (1) and kidney (2) were biopsied with a coaxial technique using a 16-G biopsy needle guided by a T1-weighted three-dimensional gradient recalled echo volumetric interpolated breath-hold examination (T1w-3D-GRE-VIBE) sequence. Sensitivity, specificity, accuracy, complication rate, interventional complexity, room/intervention time and needle artefacts were determined. A sensitivity of 0.93, specificity of 1.0 and accuracy of 0.94 were observed. Three patients required a rebiopsy. There was a minor complications rate of 13.6%, and no major complications were observed. Histopathology revealed 38 malignant lesions, and 3-month follow-up confirmed 9 benign lesions. Mean lesion diameter was 3.4 {+-} 3.1 cm (50% being smaller than 2 cm). Mean needle tract length was 10.8 {+-} 3.3 cm. Median room time was 42.0 {+-} 19.8 min and intervention time 9.3 {+-} 8.1 min. Needle artefact size was about 9-fold greater for perpendicular access versus access parallel to the main magnetic field. Biopsies of the upper abdomen can be performed with great technical success and easy handling because of the large-bore diameter. The MRI-guided biopsy needle had an acceptable susceptibility artefact at 3 T. However future research must aim to reduce the susceptibility effects of the biopsy systems. (orig.)

  6. Abdominal emergencies in pediatrics. (United States)

    Coca Robinot, D; Liébana de Rojas, C; Aguirre Pascual, E


    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition.

  7. [Intestinal occlusion and abdominal compartment syndrome (ACS)]. (United States)

    Stagnitti, Franco


    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

    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

    Lee, Ser Yee; Pormento, James G; Koong, Heng Nung


    Abdominal paracentesis and thoracocentesis are common bedside procedures with diagnostic, therapeutic and palliative roles. We describe a useful and familiar a useful and familiar technique with the use of a multiple lumen catheter commonly used for central venous line insertion for drainage of ascites or moderate to large pleural effusions. The use of a multiple lumen catheter allows easier and more rapid aspiration of fluid with a smaller probability of the side holes being blocked as compared to the standard needle or single catheter methods. This is particularly useful in situations where the dedicated commercial kits for thoracocentesis and abdominal paracentesis are not readily available.

  10. [Abdominal actinomycosis with IUD]. (United States)

    Kamprath, S; Merker, A; Kühne-Heid, R; Schneider, A


    We report a case of abdominal actinomycosis in a 54 year old woman using an intrauterine device for a period of 8 years. The most important finding was a tuboovarialabscess at the left pelvic side with involvement of the serosa of the jejunum, ileum, sigma, and omentum majus. Intraoperative exploration showed a solid retroperitoneal infiltration between the pelvic side wall and sigma. Another infiltration was found on the left side of the abdominal wall. The diagnosis was confirmed by histopathological examination and the patient was treated by a combination of Aminopenicillin and Metronidazol. After a period of three months we observed a complete regression of the clinical and the MRI findings.

  11. Adult abdominal hernias.

    LENUS (Irish Health Repository)

    Murphy, Kevin P


    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.

    Full Text Available Alberto Palazzuoli, Maddalena Gallotta, Giuseppe Guerrieri, Ilaria Quatrini, Beatrice Franci, et alDepartment of Internal Medicine and Metabolic Diseases, Unit of Aortic Surgery, University of Siena, ItalyBackground: Abdominal aortic aneurysm (AAA is considered a manifestation of atherosclerosis, however there are epidemiologic, biochemical, and structural differences between occlusive atherosclerosis and AAA. The pathogenesis of AAA involves several factors, first of all destruction of collagen and elastin in the aortic wall. Classical risk factors may influence the evolution and development of AAA, though no consistent association has been found. Aims of the study were to evaluate associations between risk factors and to establish the prevalence of carotid, peripheral vascular and coronary atherosclerosis in patients with AAA.Methods: We studied 98 patients with AAA (Group 1 awaiting surgery compared with high cardiovascular risk population having two or more risk factors (n = 82 Group 2. We evaluated traditional risk factors and we studied by eco-doppler and echocardiography the presence of carotid peripheral and coronaric atherosclerosis in two groups.Results: We found a higher incidence of AAA in males (p < 0.01. The prevalence of infrarenal AAA was significantly higher than suprarenal AAA (81 vs 17 p < 0.001. No differences in total cholesterol (199 ± 20 vs. 197 ± 25 mg/dl, low-density lipoprotein (142 ± 16 vs. 140 ± 18 mg/dl, triglycerides (138 ± 45 vs. 144 ± 56 mg/dl, glycemia (119 ± 15 vs. 122 ± 20 mg/dl, and fibrinogen (388 ± 154 vs. 362 ± 92 mg/dl were found between groups.

    Background: Abdominal auscultation has an important position in the physical examination of the abdomen. Little is known about rater agreement. The aim of this study was to describe rater agreement and thus, indirectly, the value of the examination. Methods: In a semi-virtual setup 12 recordings...... of the intestinal sounds from 8 patients with acute abdominal pain and 4 healthy volunteers were presented to 100 physicians. The physicians were asked to characterize the intestinal sounds as normal or pathologic. Fisher's exact test was used for comparison between groups of physicians. Results: Overall, 72......% of the answers with regard to healthy volunteers concluded that the sounds were normal (equalling agreement), whereas 64% of answers with regard to intestinal obstruction concluded that the sounds were pathologic (but agreement was higher due to agreement on wrong diagnosis in one case). Bowel sounds from...

    Sachs, T; Schermerhorn, M


    Ruptured abdominal aortic aneurysm (AAA) continues to be one of the most lethal vascular pathologies we encounter. Its management demands prompt and efficient evaluation and repair. Open repair has traditionally been the mainstay of treatment. However, the introduction of endovascular techniques has altered the treatment algorithm for ruptured AAA in most major medical centers. We present recent literature and techniques for ruptured AAA and its surgical management.

    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.

  18. Abdominal Cavity Eventration Treated by Means of the "Open Abdomen" Technique Using the Negative Pressure Therapy System--Case Report and Literature Review. (United States)

    Trzeciak, Piotr W; Porzeżyńska, Joanna; Ptasińska, Karolina; Walczak, Dominik A


    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.

  19. Implementation of the Continuous AutoTransfusion System (C.A.T.S) in open abdominal aortic aneurysm repair: an observational comparative cohort study.

    LENUS (Irish Health Repository)

    Tawfick, Wael A


    The use of the Continuous AutoTransfusion System (C.A.T.S; Fresenius Hemotechnology, Bad Homburg v.d.H., Germany), which conserves allogenic blood, is reported in 187 patients having abdominal aortic aneurysm repair during a 9-year period. Patients were allocated to C.A.T.S if a Haemovigilance technician was available. A mean of 685 mL of retrieved blood was reinfused in 101 patients receiving C.A.T.S; 61% required 2 U or less. All control patients required 3 U or more of allogenic blood. Allogenic transfusion in C.A.T.S patients decreased significantly (P < .0001). Mean intensive care unit stay was significantly reduced in C.A.T.S patients (P = .042). Mean postoperative hospital stay was 18 days for C.A.T.S group and 25 days in control patients (P = .014). The respective 30-day mortality was 12% versus 19% (P = .199). The C.A.T.S markedly reduced the amount of blood transfused, was associated with reduced intensive care unit and postoperative hospital stay, and was cost-effective.

  20. A Model for Precise and Uniform Pelvic- and Limb-Sparing Abdominal Irradiation to Study the Radiation-Induced Gastrointestinal Syndrome in Mice Using Small Animal Irradiation Systems (United States)

    Brodin, N. Patrik; Velcich, Anna; Guha, Chandan


    Background and Purpose: Currently, no readily available mitigators exist for acute abdominal radiation injury. Here, we present an animal model for precise and homogenous limb-sparing abdominal irradiation (LSAIR) to study the radiation-induced gastrointestinal syndrome (RIGS). Materials and Methods: The LSAIR technique was developed using the small animal radiation research platform (SARRP) with image guidance capabilities. We delivered LSAIR at doses between 14 and 18 Gy on 8- to 10-week-old male C57BL/6 mice. Histological analysis was performed to confirm that the observed mortality was due to acute abdominal radiation injury. Results: A steep dose–response relationship was found for survival, with no deaths seen at doses below 16 Gy and 100% mortality at above 17 Gy. All deaths occurred between 6 and 10 days after irradiation, consistent with the onset of RIGS. This was further confirmed by histological analysis showing clear differences in the number of regenerative intestinal crypts between animals receiving sublethal (14 Gy) and 100% lethal (18 Gy) radiation. Conclusion: The developed LSAIR technique provides uniform dose delivery with a clear dose response, consistent with acute abdominal radiation injury on histological examination. This model can provide a useful tool for researchers investigating the development of mitigators for accidental or clinical high-dose abdominal irradiation. PMID:28203121

  1. [Differential diagnosis of abdominal pain]. (United States)

    Frei, Pascal


    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.

  2. Lower Abdominal Pain. (United States)

    Carlberg, David J; Lee, Stephen D; Dubin, Jeffrey S


    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation.

    The purpose of this article is to provide an up to date review on the spectrum of applications of perfusion computed tomography (CT) in the abdomen. New imaging techniques have been developed with the objective of obtaining a structural and functional analysis of different organs. Recently, perfusion CT has aroused the interest of many researchers who are studying the applicability of imaging modalities in the evaluation of abdominal organs and diseases. Per-fusion CT enables fast, non-invasive imaging of the tumor vascular physiology. Moreover, it can act as an in vivo biomarker of tumor-related angiogenesis.

    A device that generates negative extra-abdominal pressure (ABDOPRE) for treatment of patients with high intra-abdominal pressure was developed. It includes pressure sensors for transducing intra-abdominal pressure through an intra-vesical catheter and negative pressure in the vacuum bell which is placed over the abdomen. By means of a control system, a pattern for reducing IAP is set, according to a clinical protocol. The external negative pressure is generated using a vacuum pump connected to the bell. The system registers the values of interest for the medical history. The system is being tested over ICU patients, registering a satisfactory IAP reduction.

    Energy Technology Data Exchange (ETDEWEB)

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


    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.)

  11. Abdominal migraine in the differential diagnosis of acute abdominal pain. (United States)

    Cervellin, Gianfranco; Lippi, Giuseppe


    Although traditionally regarded as a specific pediatric disease, abdominal migraine may also be observed in adults. Unfortunately, however, this condition is frequently overlooked in the differential diagnosis of abdominal pain in the emergency department (ED). A 30-year-old woman presented to our ED complaining of abdominal pain and vomiting, lasting for 12 hours. The pain was periumbilical, continuous, and not associated with fever or diarrhea. The physical examination and the results of conventional blood tests were normal. The patient was treated with intravenous ketoprofen, metoclopramide, and ranitidine, obtaining a prompt relief of symptoms. She had a history of similar episodes in the last 15 years, with several ED visits, blood test examinations, ultrasonography of the abdomen, and upper gastrointestinal endoscopies. Celiac disease, porphyry, sickle cell disease, and inflammatory bowel disease were all excluded. In July 2012, she became pregnant, and she delivered a healthy baby on April 2013. Until November 2014, she has remained asymptomatic. Based on the clinical characteristics of the abdominal pain episodes, the exclusion of any alternative diagnosis, and the relief of symptoms during and after pregnancy, a final diagnosis of abdominal migraine could be established. A skilled emergency physician should always consider abdominal migraine in the differential diagnosis of patients admitted to the ED with abdominal pain, especially when the attacks are recurrent and no alternative diagnosis can be clearly established.

  12. Pre-eclampsia renamed and reframed: Intra-abdominal hypertension in pregnancy. (United States)

    Sawchuck, Diane J; Wittmann, Bernd K


    This hypothesis proposes pre-eclampsia is caused by intra-abdominal hypertension in pregnancy. Sustained or increasing intra-abdominal pressure ⩾12mmHg causes impaired venous return to the heart, systemic vascular resistance, ischemia reperfusion injury, intestinal permeability, translocation of lipopolysaccharide endotoxin to the liver, cytotoxic immune response, systemic inflammatory response, pressure transmission to thoracic and intra-cranial compartments, and multi-organ dysfunction. This hypothesis is predicated on Pascal's law, evidence founded in the intra-abdominal hypertension literature, and the adapted equation ΔIAP-P=ΔIAVF/Cab, where ΔIAP-P=change in intra-abdominal pressure in pregnancy, ΔIAVF=change in intra-abdominal vector force (volume and force direction) and Cab=abdominal compliance. Factors causing increased intra-abdominal pressure in pregnancy include: progressive uterine expansion, obstetrical factors that increase intra-uterine volume excessively or acutely, maternal anthropometric measurements that affect intra-abdominal pressure thresholds, maternal postures that increase abdominal force direction, abdominal compliance that is decreased, diminished with advancing gestation, or has reached maximum expansion, habitation at high altitude, and rapid drops in barometric pressure. We postulate that the threshold for lipopolysaccharide translocation depends on the magnitude of intra-abdominal pressure, the intestinal microbiome complex, and the degree of intestinal permeability.

    Human body's abdominal fat content can be divided into SFA( Subcutaneous Fat Area) and VFA( Visceral Fat Area)according to the depth,two kinds of fat content has certain effects on human health,in order to avoid the measurement of different depth of abdominal fat content caused by their mutual interference. This paper introduces a design based on the bioimpedance spectroscopy method BIS ( bioimpedance spectroscopy ) for the measurement of the human abdominal fat device. The device adopts four electrodes and multi-frequency bioelectrical impedance measurement system, mainly including the programmable signal generator module and the amplitude and phase detection module. According to the selection of the best relative fixed electrode position and the appropriate measurement scheme,the corresponding depth of abdominal fat content can be calculated. The result indicates that the system is stable and reliable, with sufficient accuracy, precision and good repeatability. So for the traditional impedance analysis measurement systems with BIS which needs only measuring a single depth abdominal fat content has an important reference meaning help.%人体的腹部脂肪含量按深度可以分为皮下脂肪SFA(Subcutaneous Fat Area)和内脏脂肪VFA(Visceral Fat Area),两种脂肪的含量对人体健康具有一定的影响,为了避免测量不同深度的腹部脂肪含量造成的相互干扰.设计了一种基于多频生物电阻抗法BIS(Bioimpedance Spectroscopy)测量人体腹部脂肪的装置,该装置采用四电极多频率的生物电阻抗测量系统,主要包括程控信号发生器模块和幅度相位检测模块.根据选择的最佳的电极相对固定位置及合适的测量方案,可以计算出相应深度的腹部脂肪含量.实测表明该系统稳定可靠,具有足够的测量精度、准确度与重复性好等特点.所以对于传统的借助于生物电阻抗法测量单一深度的腹部脂肪含量的测量系统具有重要的借鉴意义.

    Diagnostic imaging is often an integral component in the workup of a pediatric patient with acute abdominal pain. The purpose of this study was to compare the diagnostic value of a three-view acute abdominal series (AAS) with that of a single supine view (SSV) in children with acute abdominal pain. All subjects aged ≤18 years that underwent an emergency three-view AAS examination for acute abdominal pain at a single urban hospital system were included. Retrospective evaluation of radiological diagnosis, number of radiological images, further imaging, management, and clinical outcomes was performed. "Positive" AAS studies were compared with corresponding SSV images for direct comparison of diagnostic value. Standard nonparametric statistical evaluation was performed. Five hundred forty-one AAS studies were included in the study. Greater than three radiographs were acquired in 29 % (153/541) of the subjects. Two hundred ninety-nine out of 541 AAS studies included a technically adequate SSV of the abdomen and pelvis. Most AAS examinations were categorized as negative (n = 485; 90 %). Of the 56 examinations initially classified as positive, there was no significant statistical difference between diagnostic accuracy between the AAS and SSV on retrospective evaluation. For pediatric subjects with nontraumatic acute abdominal pain, the yield of conventional radiographic study is exceedingly low. If required, a technically adequate single supine anteroposterior (AP) view of the abdomen and pelvis is sufficient for initial radiographic evaluation while reducing unnecessary radiation exposure to the patient.

  16. Effect of functional sympathetic nervous system impairment of the liver and abdominal visceral adipose tissue on circulating triglyceride-rich lipoproteins (United States)

    Cirnigliaro, Christopher M.; Kirshblum, Steven C.; McKenna, Cristin


    Background Interruption of sympathetic innervation to the liver and visceral adipose tissue (VAT) in animal models has been reported to reduce VAT lipolysis and hepatic secretion of very low density lipoprotein (VLDL) and concentrations of triglyceride-rich lipoprotein particles. Whether functional impairment of sympathetic nervous system (SNS) innervation to tissues of the abdominal cavity reduce circulating concentrations of triglyceride (TG) and VLDL particles (VLDL-P) was tested in men with spinal cord injury (SCI). Methods One hundred-three non-ambulatory men with SCI [55 subjects with neurologic injury at or proximal to the 4th thoracic vertebrae (↑T4); 48 subjects with SCI at or distal to the 5th thoracic vertebrae (↓T5)] and 53 able-bodied (AB) subjects were studied. Fasting blood samples were obtained for determination of TG, VLDL-P concentration by NMR spectroscopy, serum glucose by autoanalyzer, and plasma insulin by radioimmunoassay. VAT volume was determined by dual energy x-ray absorptiometry imaging with calculation by a validated proprietary software package. Results Significant group main effects for TG and VLDL-P were present; post-hoc tests revealed that serum TG concentrations were significantly higher in ↓T5 group compared to AB and ↑T4 groups [150±9 vs. 101±8 (p<0.01) and 112±8 mg/dl (p<0.05), respectively]. VLDL-P concentration was significantly elevated in ↓T5 group compared to AB and ↑T4 groups [74±4 vs. 58±4 (p<0.05) and 55±4 μmol/l (p<0.05)]. VAT volume was significantly higher in both SCI groups than in the AB group, and HOMA-IR was higher and approached significance in the SCI groups compared to the AB group. A linear relationship between triglyceride rich lipoproteins (i.e., TG or Large VLDL-P) and VAT volume or HOMA-IR was significant only in the ↓T5 group. Conclusions Despite a similar VAT volume and insulin resistance in both SCI groups, the ↓T5 group had significantly higher serum TG and VLDL-P values than

  17. Economics of abdominal wall reconstruction. (United States)

    Bower, Curtis; Roth, J Scott


    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.

  18. Micromanaging Abdominal Aortic Aneurysms

    Directory of Open Access Journals (Sweden)

    Lars Maegdefessel


    Full Text Available The contribution of abdominal aortic aneurysm (AAA disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta. This work aims to develop novel diagnostic and therapeutic strategies to limit AAA expansion and, ultimately, rupture. Contributions from multiple research groups have uncovered a complex transcriptional and post-transcriptional regulatory milieu, which is believed to be essential for maintaining aortic vascular homeostasis. Recently, novel small noncoding RNAs, called microRNAs, have been identified as important transcriptional and post-transcriptional inhibitors of gene expression. MicroRNAs are thought to “fine tune” the translational output of their target messenger RNAs (mRNAs by promoting mRNA degradation or inhibiting translation. With the discovery that microRNAs act as powerful regulators in the context of a wide variety of diseases, it is only logical that microRNAs be thoroughly explored as potential therapeutic entities. This current review summarizes interesting findings regarding the intriguing roles and benefits of microRNA expression modulation during AAA initiation and propagation. These studies utilize disease-relevant murine models, as well as human tissue from patients undergoing surgical aortic aneurysm repair. Furthermore, we critically examine future therapeutic strategies with regard to their clinical and translational feasibility.

  19. Abdominal aortic feminism. (United States)

    Mortimer, Alice Emily


    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer.

  1. The effect of abdominal massage in reducing malignant ascites symptoms. (United States)

    Wang, Tsae-Jyy; Wang, Hung-Ming; Yang, Tsai-Sheng; Jane, Sui-Whi; Huang, Tse-Hung; Wang, Chao-Hui; Lin, Yi-Hsin


    As many as 50% of end-stage cancer patients will develop ascites and associated symptoms, including pain, tiredness, nausea, depression, anxiety, drowsiness, loss of appetite, dyspnea, perceived abdominal bloating, and immobility. Abdominal massage may stimulate lymph return to the venous system and reduce ascites-related symptoms. The purpose of this study was to test the effect of abdominal massage in reducing these symptoms and reducing ascites itself as reflected in body weight. For a randomized controlled design using repeated measures, a sample of 80 patients with malignant ascites was recruited from gastroenterology and oncology units of a medical center in northern Taiwan and randomly assigned to the intervention or the control group. A 15-minute gentle abdominal massage, using straight rubbing, point rubbing, and kneading, was administered twice daily for 3 days. The control group received a twice-daily 15-minute social interaction contact with the same nurse. Symptoms and body weight were measured in the morning for 4 consecutive days from pre- to post-test. In generalized estimation equation modeling, a significant group-by-time interaction on depression, anxiety, poor wellbeing, and perceived abdominal bloating, indicated that abdominal massage improved these four symptoms, with the greatest effect on perceived bloating. The intervention had no effect on pain, tiredness, nausea, drowsiness, poor appetite, shortness of breath, mobility limitation, or body weight. Abdominal massage appears useful for managing selected symptoms of malignant ascites.

    We report the case of a 15-year-old boy suffering from progressive dyspnea on exertion and painful abdominal protrusion. Final diagnosis of intra-abdominal tuberculosis (TB), including lymphadenopathy and abdominal abscess formation, was made following elective laparotomy. This type of disease is a rare manifestation of extrapulmonary tuberculosis. The imaging findings in unenhanced and contrast-enhanced MRI and laparoscopic images are presented. Differential diagnosis of abdominal abscess formation and other fungal or bacteriological infections, as well as the imaging findings of this type of lesion, are discussed. This case demonstrates that atypical manifestation of TB may remain unrecognized; thus, awareness of this kind of manifestation of tuberculosis may prevent patients from being subjected to inappropriate therapies.

  6. Updates on abdominal desmoid tumors

    Institute of Scientific and Technical Information of China (English)


    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.

  7. Maternal low-protein diet up-regulates the neuropeptide Y system in visceral fat and leads to abdominal obesity and glucose intolerance in a sex- and time-specific manner


    Han, Ruijun; Li, Aiyun; Lijun LI; Kitlinska, Joanna B.; Zukowska, Zofia


    Neuropeptide Y (NPY) mediates stress-induced obesity in adult male mice by activating its Y2 receptor (Y2R) in visceral adipose tissue (VAT). Here, we studied whether the NPY-Y2R system is also activated by maternal low-protein diet (LPD) and linked to obesity in offspring. Prenatal LPD offspring had lower birth weights compared to normal-protein diet (NPD) offspring. Female prenatal and lactation stress (PLS) offspring from mothers fed an LPD developed abdominal adiposity and glucose intoler...

  8. Common abdominal emergencies in children. (United States)

    D'Agostino, James


    Because young children often present to EDs with abdominal complaints, emergency physicians must have a high index of suspicion for the common abdominal emergencies that have serious sequelae. At the same time, they must realize that less serious causes of abdominal symptoms (e.g., constipation or gastroenteritis) are also seen. A gentle yet thorough and complete history and physical examination are the most important diagnostic tools for the emergency physician. Repeated examinations and observation are useful tools. Physicians should listen carefully to parents and their children, respect their concerns, and honor their complaints. Ancillary tests are inconsistent in their value in assessing these complaints. Abdominal radiographs can be normal in children with intussusception and even malrotation and early volvulus. Unlike the classic symptoms seen in adults, young children can display only lethargy or poor feeding in cases of appendicitis or can appear happy and playful between paroxysmal bouts of intussusception. The emergency physician therefore, must maintain a high index of suspicion for serious pathology in pediatric patients with abdominal complaints. Eventually, all significant abdominal emergencies reveal their true nature, and if one can be patient with the child and repeat the examinations when the child is quiet, one will be rewarded with the correct diagnosis.

    Emmanuel Olorundare Ojo


    Full Text Available Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7% males and 20 (18.3% females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years. The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%, colon 48 (44%, and liver 41 (37.6%. Forty-four (40.4% patients had extra-abdominal injuries involving the chest in 17 (15.6%, musculoskeletal 12 (11%, and the head in 9 (8.3%. The most prevalent weapon injuries were gunshot 76 (69.7%, explosives 12 (11%, stab injuries 11 (10.1%, and blunt abdominal trauma 10 (9.2%. The injury severity score varied from 8 to 52 (mean: 20.8 with a fatality rate of 11 (10.1% and morbidity rate of 29 (26.6%. Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

  10. Abdominal leiomyosarcomas: radiologic appearances at various locations

    Energy Technology Data Exchange (ETDEWEB)

    Kurugoglu, Sebuh; Ogut, Gunduz; Mihmanli, Ismail; Korman, Ugur [Department of Radiology, Istanbul University, Cerrahpasa Medical Faculty, 34300 Istanbul (Turkey); Durak, Haydar [Department of Pathology, Istanbul University, Cerrahpasa Medical Faculty, 34300 Istanbul (Turkey)


    Leiomyosarcomas are soft tissue tumors that account for approximately 15% of all soft tissue sarcomas. Leiomyosarcomas may be located at almost any part of the abdomen but especially are more common in the retroperitoneum, followed by gastrointestinal tract and genital system. They develop mainly in adult life and are very rare in children. In this article, imaging findings of leiomyosarcomas in various abdominal locations are presented. Radiologic studies are capable of providing useful information on the localization, size, changes in the internal structure of the tumor, its extension and invasion. Leiomyosarcoma should be considered in the differential diagnosis in case of detection of a large, circumscribed, and heterogenous abdominal mass. Histopathologically, diagnosis of malignancy depends particularly on mitotic counts, size, rate of necrosis, and infiltrating margins. (orig.)

    Li, Q; Zhao, X L; Gilbert, E R; Liu, Y P; Wang, Y; Qiu, M H; Zhu, Q


    Free-range production system is increasingly being used in poultry breeding and feed production in many countries. The objective of the current experiment was to evaluate the effects of different raising systems on fat-related traits and mRNA levels of liver lipogenesis genes in Erlang Mountainous chicken. Each of 10 birds (91 day old) from caged, indoor-floor housed, and free-range housing systems was slaughtered, and fat-related traits, live body weight (BW), subcutaneous fat thickness (SFT), abdominal fat weight (AFW), abdominal fat percentage (AFP), and intramuscular fat content were determined. The mRNA levels of liver X receptor α, carbohydrate response element-binding protein (ChREBP), sterol regulatory element-binding protein-1 (SREBP1), and fatty acid synthase were detected. The caged chicken exhibited significantly higher BW, SFT, and AFW than those of free-ranged chicken (P caged chicken, while the lowest level was found in free-ranged chicken. Association analysis indicated that there were significant (P caged chicken was probably induced by increased gene expression of ChREBP and SREBP1 in the liver.

  12. Maternal low-protein diet up-regulates the neuropeptide Y system in visceral fat and leads to abdominal obesity and glucose intolerance in a sex- and time-specific manner. (United States)

    Han, Ruijun; Li, Aiyun; Li, Lijun; Kitlinska, Joanna B; Zukowska, Zofia


    Neuropeptide Y (NPY) mediates stress-induced obesity in adult male mice by activating its Y2 receptor (Y2R) in visceral adipose tissue (VAT). Here, we studied whether the NPY-Y2R system is also activated by maternal low-protein diet (LPD) and linked to obesity in offspring. Prenatal LPD offspring had lower birth weights compared to normal-protein diet (NPD) offspring. Female prenatal and lactation stress (PLS) offspring from mothers fed an LPD developed abdominal adiposity and glucose intolerance associated with a 5-fold up-regulation of NPY mRNA and a 6-fold up-regulation of Y2R mRNA specifically in VAT, in addition to elevated platelet-rich-plasma (PRP) NPY, compared to control females fed a high-fat diet (HFD). Conversely, PLS male offspring showed lower NPY in PRP, a 10-fold decrease of Y2R mRNA in VAT, lower adiposity, and improved glucose tolerance compared to control males. Interestingly, prenatal LPD offspring cross-fostered to control lactating mothers had completely inverse metabolic and NPY phenotypes. Taken together, these findings suggested that maternal LPD activates the VAT NPY-Y2R system and increases abdominal adiposity and glucose intolerance in a sex- and time-specific fashion, suggesting that the peripheral NPY system is a potential mediator of programming for the offspring's vulnerability to obesity and metabolic syndrome.

  13. The potential participation of abdominal pressure in preeclampsia. (United States)

    Zhang, Andy K


    Preeclampsia is a major cause of maternal and perinatal mortality and morbidity. Regardless of susceptibility or predisposing conditions and risk factors, the degree of increase in abdominal pressure is directly related to the severity of preeclampsia, particularly in women with hydatidiform mole. When increased abdominal pressure is normalized by delivery, preeclampsia is cured. Recent genetic studies highlighted two leading risk factors for preeclampsia: chronic renal disease and T235 homozygosity for the AGT gene. Thus, while there is increased abdominal pressure in pregnancy, an imbalanced renin angiotensin system and renal injuries lead to a vicious cycle of increasing abdominal pressure and further renal injuries. A hypothesis for the potential participation of pressure in preeclampsia is described and the amelioration of preeclampsia through postural intervention and the possible therapeutic effect of angiotensin is suggested.

    Englbrecht, J S; Pogatzki-Zahn, E M


    Abdominal and thoracic surgical procedures can result in significant acute postoperative pain. Present evidence shows that postoperative pain management remains inadequate especially after "minor" surgical procedures. Various therapeutic options including regional anesthesia techniques and systemic pharmacotherapy are available for effective treatment of postoperative pain. This work summarizes the pathophysiological background of postoperative pain after abdominal and thoracic surgery and discusses the indication, effectiveness, risks, and benefits of the different therapeutic options. Special focus is given to the controversial debate about the indication for epidural analgesia, as well as various alternative therapeutic options, including transversus abdominis plane (TAP) block, paravertebral block (PVB), wound infiltration with local anesthetics, and intravenous lidocaine. In additional, indications and contraindications of nonopioid analgesics after abdominal and thoracic surgery are discussed and recommendations based on scientific evidence and individual risk and benefit analysis are made. All therapeutic options discussed are eligible for clinical use and may contribute to improve postoperative pain outcome after abdominal and thoracic surgical procedures.

    Lindstedt, Sandra; Malmsjö, Malin; Hlebowicz, Joanna; Ingemansson, Richard


    This study aimed to compare the changes in microvascular blood flow in the small intestinal wall, wound contraction and fluid evacuation, using the established V.A.C. abdominal dressing (VAC dressing) and a new abdominal dressing, the ABThera open abdomen negative pressure therapy system (ABThera dressing), in negative pressure wound therapy (NPWT). Midline incisions were made in 12 pigs that were subjected to treatment with NPWT using the VAC or ABThera dressing. The microvascular blood flow in the intestinal wall was measured before and after the application of topical negative pressures of −50, −75 and −125mmHg using laser Doppler velocimetry. Wound contraction and fluid evacuation were also measured. Baseline blood flow was defined as 100% in all settings. The blood flow was significantly reduced to 64·6±6·7% (P blood flow was significantly reduced to 39·6±6·7% (P blood flow could be observed between the two groups. The ABThera system afforded significantly better fluid evacuation from the wound, better drainage of the abdomen and better wound contraction than the VAC dressing.

    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

    Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths. We report a case of a patient with 27 years old, and diagnosis of 25.2 weeks of pregnancy, prior placenta and anhidramnios, referred due to difficult in uterine contour delimitation, easy palpation of fetal parts, cephalic pole in left hypochondrious and presence of mass in hypogastria, no delimitations, pain with mobilization, no transvaginal bleed and fetal movements. Interruption of pregnancy is decided by virtue of severe oligohidramnios, retardation in fetal intrabdominal growth, and recurrent maternal abdominal pain. Surgical intervention was carried out for resolution of the obstetrical event, in which was found ectopic abdominal pregnancy with bed placental in right uterine horn that corresponded to a pregnancy of 30 weeks of gestation. Abdominal pregnancy is still a challenge for obstetrics due to its diagnosis and treatment. Early diagnosis is oriented to prevent an intrabdominal hemorrhage that is the main maternal cause of mortality.

No major complications were reported following hernia repair before or during pregnancy. The combined procedure of elective cesarean section and abdominal wall hernia repair was reported...

  1. Abdominal actinomycosis mimicking acute appendicitis. (United States)

    Conrad, Robert Joseph; Riela, Steven; Patel, Ravi; Misra, Subhasis


    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

  2. [Abdominal wall closure by incisional hernia and herniation after laparostoma]. (United States)

    Mischinger, H-J; Kornprat, P; Werkgartner, G; El Shabrawi, A; Spendel, S


    As hernias and abdominal wall defects have a variety of etiologies each with its own complications and comorbidities in various constellations, efficient treatment requires patient-oriented management. There is no recommended standard treatment and the very different clinical pictures demand an individualized interdisciplinary approach. Particularly in the case of complicated hernias, the planning of the operation should focus on the problems posed by the individual patient. Treatment mainly depends on the etiology of the hernia, immediate or long-term complications and the efficiency of individual repair techniques. Abdominal wall repair for recurrent herniation requires direct closure of the fascia generally using the sublay technique with a lightweight mesh. It is still unclear whether persistent inflammation, mesh dislocation, fistula formation or other long-term complications are due to certain materials or to the surgical technique. With mesh infections it has been shown to be advantageous to remove a polytetrafluoroethylene (PTFE) mesh, while the combination of systemic and local treatment appears to suffice for a polypropylene or polyester mesh. Heavier meshes in the sublay position or plastic reconstruction with autologous tissue are indicated as substitutes for the abdominal wall for giant hernias, repeated recurrences and large abdominal wall defects. A laparostoma is increasingly more often created to treat septic intra-abdominal processes but is very often responsible for a complicated hernia. If primary repair of the abdominal wall is not an option, resorbable material or split skin is used for coverage under the auspices of a planned hernia repair.

    Full Text Available OBJETIVO: A implantação de eletrodos intra-abdominais para captura de sinais de onda elétrica constitui instrumento de estudo da atividade mioelétrica do tubo gastrointestinal. O deslocamento destes eletrodos do local de implantação ocorre com certa freqüência em animais de experimentação não anestesiados, devido aos movimentos da musculatura diafragmática, abdominal, do peristaltismo gastrintestinal e sobretudo aos hábitos inerentes à espécie de animal estudada, particularmente presentes em caninos. No referido estudo foi proposto um procedimento que proporciona estabilidade ao referido sistema utilizando-se recursos simples e de custos irrelevantes. MÉTODOS: Os autores apresentam através de diagramas e fotos um sistema de ancoração dos eletrodos elétricos na pele dos animais com botões. RESULTADOS: Foram realizados 5 experimentos, fixando-se em cada animal 3 eletrodos bipolares. Os animais foram mantidos em repouso até a completa recuperação do íleo paralítico. Não foi identificado nos animais estudados nenhuma migração dos eletrodos. CONCLUSÃO: O procedimento proposto é eficiente, simples, de fácil confecção e permite o monitoramento da atividade mioelétrica, em cães não anestesiados, por períodos de tempo prolongado.OBJECTIVE: The use of intra-abdominal electrodes in the study of gastrointestinal electrical wave is an important instrument of the gastrointestinal mioelectric activity.

    The purpose of our study is to demonstrate the value of CT in the emergency department (ED) for patients with non-traumatic abdominal pain. Between August 1998 and April 1999, 536 consecutive patients with non-traumatic abdominal pain were entered into our study. Using a computer order entry system, physicians were asked to identify: (a) their most likely diagnosis; (b) their level of certainty in their diagnosis; (c) if they thought CT would be normal or abnormal; (d) their treatment plan (prior to knowledge of the CT results); and (e) their role in deciding to order CT. This information was correlated with each patient's post-CT diagnosis and subsequent management. Pre- and post-CT diagnoses were concordant in 200 of 536 (37%) patients. The physicians' certainty in the accuracy of their pre-CT diagnosis was less than high in 88% of patients. Prior to CT, the management plan included hospital admission for 402 patients. Following CT, only 312 patients were actually admitted; thus, the net impact of performing CT was to obviate the need for hospital admission in 90 of 536 (17%) of patients with abdominal pain. Prior to CT, 67 of 536 (13%) of all patients would have undergone immediate surgery; however, following CT only 25 (5%) actually required immediate surgery. Among patients with the four most common pre-CT diagnoses (appendicitis, abscess, diverticulitis, and urinary tract stones) CT had the greatest impact on hospital admission and surgical management for patients with suspected appendicitis. For patients with suspected appendicitis, CT reduced the hospital admission rate in 28% (26 of 91) of patients and changed the surgical management in 40% (39 of 91) of patients. Our study demonstrates the advantage of performing abdominal CT in the ED for patients with non-traumatic abdominal pain. (orig.)

    Rifat, Sami F; Gilvydis, Rimas P


    Abdominal injuries are rare in sports, but when they do occur it is important that the physician recognize the warning signs of potentially life-threatening injury to the liver, spleen, or hollow abdominal viscera. Though the sports medicine physician may not always provide definitive treatment of many of these conditions, he or she should be familiar with the preferred diagnostic modalities and latest treatment options. This information is not only essential to appropriately participate in treatment decisions, but is also important in order to make return-to-play determinations.

    Sukkarieh, F; Brasseur, P; Bissen, L


    The authors report the case of a 93-year old woman referred to the emergency department and presenting with an intestinal obstruction. Abdominal CT reveals a biliary ileus caused by the migration and the impaction of a 3 cm gallstone in the small bowel. Surgical treatment by enterolithotomy was successful. In over 90% of cases, gallstone ileus is a complication of cholelithiasis and accounts for 25% of intestinal obstruction in patients over 65 years. To reduce morbidity and mortality, early diagnosis and prompt treatment are essential. Abdominal CT-scan is the gold standard technique.

    The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

    陈哲宇; 齐清会


    Objective: To observe the clinical efficacy and mechanism of Kangyanling (KYL) in treating patients with systemic inflammatory reaction syndrome and multi-organ dysfunction syndrome (SIRS/MODS) after abdominal surgery. Methods: Eighty-two patients of SIRS/MODS after abdominal surgery were divided into two groups according to admission time, the KYL treated group (n=35) and the control group (n=47). The levels of serum C-reactive protein (CRP), plasma tumor necrosis factor α (TNFα) and interleukin-6 (IL-6) were measured at the 1st, 3rd and 7th days post-operationally. Results: The levels of CRP, TNFα and IL-6 decreased gradually after surgical operation in both groups, but the reducing velocity was shorter in the KYL group than that in the control group, so the comparison of the levels in the two groups showed significant difference on the 3rd day after operation. Conclusion:KYL could inhibit the release of inflammatory mediator and relieve the inflammatory response so as to treat post-operational SIRS/MODS effectively.

    Objective: To improve the prognosis of patients with abdominal trauma. Methods: Between January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years ranging from 3-82 years. All abdominal traumas consisted of closed traumas 360 cases, 86.7% and open traumas 55 cases, 13.3%. Results: Atotal of 407 cases 98.1% were fully recovered from trauma and the other 8 cases 1.9% died of multiple injuries. The mean injury severity score ISS of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds 6 cases, pancreatic fistula 2 cases and intestinal fistula 1 case. All these postoperative complications were cured by the conservative treatment. Conclusion: Careful case history inquisition and physical examination are the basic methods to diagnose abdomi- nal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

    Negative pressure wound therapy (NPWT) is an effective treatment for various non-healing wounds, and V.A.C.(®) Therapy was the first-approved NPWT device by the Japanese government in 2009. We report the case of a 19-week pregnant patient where V.A.C.(®) Therapy was applied to her dehisced laparotomy wound with satisfactory results. The patient was a 30-year-old female who was referred to our hospital from her previous doctor because of the presence of an ovarian cyst on the left ovary. The patient presented at 14 weeks into her pregnancy, and surgery was considered because of no reduction in the size of the cyst. An oophorocystectomy was performed, and then the surgical incision was re-opened at postoperative day (POD) 10 due to a surgical site infection. V.A.C.(®) Therapy was initiated on POD 26 (20 weeks of pregnancy) and continued for 28 days. After 28 days of V.A.C.(®) Therapy (POD 54), the wound was sutured for complete closure. The foetus did not experience any adverse affects from the surgery and, subsequently, normal vaginal delivery was achieved. This case is the first report of the use of V.A.C.(®) Therapy over a dehisced abdominal wound on a pregnant patient in our country.

  1. Thermography Examination of Abdominal Area Skin Temperatures in Individuals With and Without Focal-Onset Epilepsy. (United States)

    King, Hollis H; Cayce, Charles Thomas; Herrin, Jeph

    Early osteopathic theory and practice, and the work of the medical intuitive Edgar Cayce suggested that the abdominal areas of individuals with epilepsy would manifest "cold spots." The etiology for this phenomenon was thought to be abdominal adhesions caused by inflammation and viscero-somatic reflexes caused by adhesions or injury to visceral or musculoskeletal system structures. Indeed, until that advent of electroencephalography in the 1930s, medical practice regarding epilepsy focused on abdominal neural and visceral structures. Following two hypotheses were formulated to evaluate any abdominal temperature phenomena: (1) an abdominal quadrant division analysis would find one or more quadrants "colder" in the focal-onset epilepsy group (ICD9-CM 345.4 and 345.5) compared to controls. (2) Total abdominal areas of individuals with focal-onset epilepsy wound be colder than a control group.

    Full Text Available Abdominal actinomycosis is a rare infectious disease, caused by gram positive anaerobic bacteria, that may appear as an abdominal mass and/or abscess (Wagenlehner et al. 2003. This paper presents an unusual case of a hemodynamically stable 80-year-old man who presented to the emergency department with 4 weeks of worsening abdominal pain and swelling. He also complains of a 20-bound weight loss in 2 months. A large tender palpable mass in the right upper quadrant was noted on physical exam. Laboratory studies showed a normal white blood cell count, slightly decreased hemoglobin and hematocrit, and mildly elevated total bilirubin and alkaline phosphatase. A CT with contrast was done and showed a liver mass. Radiology and general surgery suspected malignancy and recommended CT guided biopsy. The sample revealed abundant neutrophils and gram positive rods. Cytology was negative for malignancy and cultures eventually grew actinomyces. High dose IV penicillin therapy was given for 4 weeks and with appropriate response transitioned to oral antibiotic for 9 months with complete resolution of symptoms.

It can be used as a guide for clinicians to differentiate the locations and qualities of diseases, confirm the principles of treatment, guide the usage of medicines, and predict the prognosis, with the rather high theoretic and academic value, deserving further research and analysis for the modern scholars.

  9. Abdominal wound closure: current perspectives

    Directory of Open Access Journals (Sweden)

    Williams ZF


    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 

  10. [Drug therapy of acute and chronic abdominal pain]. (United States)

    Streitberger, Konrad; Stüber, Frank; Kipfer Buchli, Irène; Stamer, Ulrike M


    For drug therapy a differentiation of acute and chronic pain is essential. In emergency situations of acute abdominal pain a fast diagnosis is mandatory. Analgesia should be provided as soon as possible. The different groups of analgesics should be used according to their known effects, side effects and contraindications. Postoperative pain after abdominal surgery has to be considered as a special condition of acute abdominal pain. Main treatment options are non opioid analgesics and opioids. Opioids can be administered intravenously via patient controlled analgesia (PCA) devices. In major abdominal surgery neuroaxial analgesia, preferentially administered via an epidural catheter provides excellent pain relief with positive impact on gastrointestinal motility and patients' recovery. Because of difficulties to allocate chronic abdominal pain to a specific organ, causal treatment often turns out to be difficult. Peripheral and central sensitization, as well as an alteration of the endogenous pain modulation comes to the fore in these chronic pain conditions. Co-analgesics like anticonvulsants and antidepressants are utilized to reduce sensitization and improve the endogenous pain modulating system. Non drug approaches and alternative treatment options might be useful. In contrast, orally or transcutaneously administered opioids are the principal corner stone for the treatment of cancer pain.

    Full Text Available Abstract Background Treatment of a number of complications that occur after abdominal surgeries may require that Urgent Abdominal Re-explorations (UARs, the life-saving and obligatory operations, are performed. The objectives of this study were to evaluate the reasons for performing UARs, outcomes of relaparotomies (RLs and factors that affect mortality. Methods Demographic characteristics; initial diagnoses; information from and complications of the first surgery received; durations and outcomes of UAR(s performed in patients who received early RLs because of complicated abdominal surgeries in our clinic between 01.01.2000 and 31.12.2004 were investigated retrospectively. Statistical analyses were done using the chi-square and Fisher exact tests. Results Early UAR was performed in 81 out of 4410 cases (1.8%.

    The greater omentum is the largest peritoneal fold and can be the origin of primary pathologic conditions, as well as a boundary and conduit for disease processes. Most diseases involving the omentum manifest with nonspecific and overlapping features on computed tomography (CT). In particular, varying benign disease processes of traumatic, inflammatory, vascular, or systemic origin can occur in the omentum during the follow-up period after surgery for intra-abdominal malignancy. It can be challenging for radiologists due to various spectrum of CT findings. Thus, we reviewed the CT findings of various benign omental lesions after surgery for intra-abdominal malignancy.

  14. Support Vector Machine Diagnosis of Acute Abdominal Pain (United States)

    Björnsdotter, Malin; Nalin, Kajsa; Hansson, Lars-Erik; Malmgren, Helge

    This study explores the feasibility of a decision-support system for patients seeking care for acute abdominal pain, and, specifically the diagnosis of acute diverticulitis. We used a linear support vector machine (SVM) to separate diverticulitis from all other reported cases of abdominal pain and from the important differential diagnosis non-specific abdominal pain (NSAP). On a database containing 3337 patients, the SVM obtained results comparable to those of the doctors in separating diverticulitis or NSAP from the remaining diseases. The distinction between diverticulitis and NSAP was, however, substantially improved by the SVM. For this patient group, the doctors achieved a sensitivity of 0.714 and a specificity of 0.963. When adjusted to the physicians' results, the SVM sensitivity/specificity was higher at 0.714/0.985 and 0.786/0.963 respectively. Age was found as the most important discriminative variable, closely followed by C-reactive protein level and lower left side pain.

  15. [Surgical treatment of patients for abdominal sepsis]. (United States)

    Kryvoruchko, I A; Usenko, O Iu; Andreieshchev, S A


    Results of surgical treatment of 201 patients, suffering abdominal sepsis (AS), which have occurred after operations on abdominal organs, were analyzed. Expediency of application of modern scales for the patients state severity estimation, prognostic sign-posts and dynamic of the pathological process course in every patient was substantiated. Existing systems of prognostication (APACHE II, SOFA, MODS) are applied restrictedly for diagnosis of infection in patients, what demands relaparotomy performance in presence of clinical signs of intraabdominal infection, which persists. For prognostication of the treatment result and determination of indications for relaparotomy conduction in patients, suffering severe AS and infectious-toxic shock (ITSH), the most informative is application of the Manheim's index of peritonitis together with analysis of clinico-laboratory indices for formation of groups of patients in risk, to whom reoperation is indicated. Advantages of relaparotomy "on demand" conduction were proved in comparison with "programmed" relaparotomy during the staged surgical treatment of patients, suffering severe AS and ITSH. Complex surgical treatment with substantiation of indications and choice of adequate method of intervention secures improvement of the treatment results in these severely ill patients.

    Constipation in childhood is common and its clinical assessment is often difficult. Plain abdominal radiography is simple and used to quantify constipation. Three scoring systems, those of Barr et al., Leech et al. and Blethyn et al., have been developed to quantify fecal loading on the abdominal radiograph. In order to determine which method is the most useful in clinical practice, we assessed the reproducibility of the three scoring systems. Plain abdominal radiographs from 40 clinically constipated children were retrospectively reviewed by two paediatric radiologists on two separate occasions. The radiographs were scored according to three different systems developed by Barr et al., Leech et al., Blethyn et al. Intraobserver variability and interobserver reproducibility were determined for each system. Kappa coefficients were calculated as indicators of inter- and intraobserver agreement for categorical outcome variables. The Leech score showed the highest reproducibility: the intraobserver agreement was high for both observers ({kappa} values of 0.88 and 1.00, respectively, P<0.05). Furthermore, the interobserver agreement was also high: {kappa} 0.91 in the first round and 0.84 in the second. The Leech score proved to be a highly reproducible tool for assessment of childhood constipation and is of value in clinical practice for systematic assessment of constipation on plain abdominal radiographs in children.

  17. Peritoneoscopy of the liver after abdominal surgery.

    Directory of Open Access Journals (Sweden)



    Full Text Available The incidence of intraperitoneal adhesion after abdominal surgery was studied. Peritoneoscopy was performed in 933 patients with liver diseases over the 6 year 5 month period from March 1974 to July 1980. Of the patients, 352 (37.7% had undergone an abdominal operation, and intraperitoneal adhesion was detected in 205 (58.2% of these patients. The liver was not observable in 5 out of 61 patients with adhesions after upper abdominal operations. Whereas, the liver was clearly observable in patients with lower abdominal operations in spite of adhesions. Out of the 581 patients without any abdominal operations, 30 patients (5.2% had adhesions in the abdominal cavity, and 6 of them had extensive adhesions that partially obscured the observation of liver surface. In all patients, peritoneoscopy was performed without complications by avoiding the surgical scar for puncture sites and ensuring a free air lumen before trocar puncture.

  19. Abdominal pain: a synthesis of recommendations for its correct management

    Directory of Open Access Journals (Sweden)

    Daniela Tirotta


    Full Text Available Abdominal pain represents one of the most important diagnostic challenges for any physician and its correct interpretation and management require a proper systematic approach and sometimes an urgent action. Moreover the guidelines that can be referred to for indications about the most adequate management procedures are few and often focused only on radiologic management. Consequently, the approach to abdominal pain is often empirical. Therefore, we propose a review of the literature on the diagnosis of abdominal pain, which may contribute to improve the diagnosis and treatment of this complex condition through a systematic review of the evidences available in this field. As to our methodology, we conducted an extensive search in the main guideline databases (SIGN, ICSI, NICE, National Guideline Cleringhouse, CMA Infobase, NZ Guidelines Group, National System Guidelines, Clinical Practice Guidelines Portal, eGuidelines, using as key words abdominal pain and abdominalgia. The guidelines were assessed according to the 2010 Italian version of the AGREE (Appraisal of Guidelines, Research and Evaluation II methodology. Afterwards we formulated our main recommendations associated with the corresponding levels of evidence and focused our attention on some grey areas, which we investigated with further research using Medline and the main systematic review databases (Cochrane database. The four main grey areas investigated were: hospital admission criteria, prognostic stratification, need for analgesic treatment and possibility of attributing abdominalgia to an abdominal pain syndrome. We then formulated our consesus-based recommendations on the grey areas. Abdominal pain management remains a complex issue for internists. As with other diagnostic challenges, it would be advisable to develop additional guidelines based on a multidisciplinary approach and not only focused on radiological management.

  3. Abdominal Pain in the Geriatric Patient. (United States)

    Magidson, Phillip D; Martinez, Joseph P


    With an aging population, emergency department clinicians can expect an increase in geriatric patients presenting with abdominal pain. Compared with younger patients, this patient population is less likely to present with classic symptoms, physical examination findings, and laboratory values of abdominal disease. However, the morbidity and mortality associated with elderly patients presenting with abdominal pathologic conditions are significant. For this reason, the clinician must be familiar with some subtle and not so subtle differences when caring for the geriatric patient with abdominal pain to ensure timely diagnosis and appropriate treatment.

    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. Keywords: abdominal migraine, recurrent abdominal pain, abdominal epilepsy, cyclical vomiting

  5. Percutaneous drainage of abdominal abcess

    Men, Sueleyman E-mail:; Akhan, Okan; Koeroglu, Mert


    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.

    The role of magnetic resonance angiography (MRA) in the evaluation of vascular involvement was studied in 55 patients with abdominal neoplasms. A 2-D time-of-flight (TOF) technique was used in all patients. All patients underwent CT and MR examinations before MRA. Also, MR angiograms were compared with digital subtraction angiography in 22 cases, with Doppler US in 13 cases, and with surgical findings in 20 cases. In all patients with liver neoplasms (n=29) MRA demonstrated the absence of flow in the infiltrated segments. Pericapsular neovascularization was observed in 12 patients. Portal vein involvement was correctly detected in 27 patients. In all cases MRA demonstrated in relationship between the tumor and venous structures. Portosystemic shunts were visualized in 20 of 21 patients with portal hypertension. Vena cava thrombosis (3 cases), compression (5 cases), and displacement (2 cases) were correctly demonstrated. In renal (n=6) and adrenal gland (n=3) tumors renal vein compression was correctly detected in 2 cases, displacement in 1 case, and thrombosis in 3 cases, with only 1 false-positive finding. In 7 patients with pancreatic tumors MRA demonstrated splenic vein thrombosis in 2 cases and compression in 2 cases, with one false-positive finding. Our results indicate that MRA provides precise information regarding venous vascular involvement in abdominal neoplasms, but preoperative arterial mapping is still problematic. (orig.)

    Full Text Available

    • Aortic dissection occurs when the layers of the aorta separate as a result of extra luminal cavity of blood through an intimal tear. Dissection limited to the abdominal aorta is rare. Unfortunately, the appropriate management of dissecting aneurysm of abdominal aorta is not documented yet. A 43 years old man was admitted to Al-zahra hospital in Isfahan with sudden onset of periumbilical abdominal pain. CT scan confirmed infrarenal dissection of abdominal aorta. Performing laparotomy, aorta was repaired using bifurcate collagen-coated Dacron graft. Surgical intervention with synthetic graft is recommended in patients with dissecting aortic aneurysm of infrarenal segments where the extent of dissection is limited and accessible.

  17. Pulmonary complications of abdominal wall defects. (United States)

    Panitch, Howard B


    The abdominal wall is an integral component of the chest wall. Defects in the ventral abdominal wall alter respiratory mechanics and can impair diaphragm function. Congenital abdominal wall defects also are associated with abnormalities in lung growth and development that lead to pulmonary hypoplasia, pulmonary hypertension, and alterations in thoracic cage formation. Although infants with ventral abdominal wall defects can experience life-threatening pulmonary complications, older children typically experience a more benign respiratory course. Studies of lung and chest wall function in older children and adolescents with congenital abdominal wall defects are few; such investigations could provide strategies for improved respiratory performance, avoidance of respiratory morbidity, and enhanced exercise ability for these children.

    Kang, Mun Ju; Sim, Min Seob; Shin, Tae Gun; Jo, Ik Joon; Song, Hyoung Gon; Song, Keun Jeong; Jeong, Yeon Kwon


    Abdominal computed tomography (CT) is widely used as a diagnostic tool in emergency medicine (EM) to accurately diagnose abdominal pain. EM residents must be able to offer preliminary interpretations of CT imaging. In this study, we evaluated the preliminary interpretation ability of a sample of emergency residents presented with adult abdominal CT images, and compared their results with those of radiology residents. We conducted a prospective observational study from November 16, 2008 to June 30, 2009. During this time, we gathered preliminary interpretations of consecutive abdominal CT made by emergency and radiology residents. We assessed the discrepancy rates of both samples by comparing their findings to the final reports from attending radiologists. A total of 884 cases were enrolled in the present study. The discrepancy rates of emergency and radiology residents were 16.7% and 12.2%, respectively. When female genital organs, peritoneum, adrenal glands, or the musculoskeletal system were abnormal, we found that emergency residents' preliminary interpretations of CT images were insufficient compared to those of radiology residents. Therefore more formal education is needed to emergency residents. If possible, the preliminary interpretations of radiology attending physicians are ideal until improving the ability of interpretations of emergency residents in abdomen CT.

  1. Radiologic findings of abdominal wall endometriosis

    To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer.

  2. Traumatic abdominal hernia complicated by necrotizing fasciitis. (United States)

    Martínez-Pérez, Aleix; Garrigós-Ortega, Gonzalo; Gómez-Abril, Segundo Ángel; Martí-Martínez, Eva; Torres-Sánchez, Teresa


    Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

  6. Abdominal wall actinomycosis associated with an IUD. A case report. (United States)

    Adachi, A; Kleiner, G J; Bezahler, G H; Greston, W M; Friedland, G H


    Abdominal wall actinomycosis without pelvic organ involvement in users of intrauterine contraceptive devices (IUDs) has not been reported on previously. We encountered one such patient, whose uterine cervix was colonized superficially with Actinomyces. We suggest that systemic actinomycosis be included in the differential diagnosis of pain in IUD users when Actinomyces is found on Papanicolaou smears or in endocervical curettings. Such patients should be treated with appropriate antibiotic therapy, especially prior to any surgical intervention.

    Suarez-Moreno, Roberto; Ponce-Pérez, Luis Virgilio; Margain-Paredes, Miguel Angel; Garza-de la Llave, Heriberto; Madrazo-Navarro, Mario; Espinosa-Álvarez, Arturo


    Antecedentes: la enfermedad de Churg-Strauss es poco común, idiopática, caracterizada por hipereosinofilia en sangre y tejidos, aunada a vasculitis sistémica en pacientes con antecedentes de asma o rinitis alérgica. Las manifestaciones gastrointestinales del síndrome de Churg Strauss se caracterizan por dolor abdominal, seguido de diarrea y hemorragia en 31-45% de los casos. Caso clínico: paciente masculino con antecedente de asma que acudió a consulta por abdomen agudo con probable apendicitis aguda; durante el protocolo de estudio se diagnosticó síndrome de Churg Strauss, con manifestaciones intestinales. Conclusión: el síndrome de Churg Strauss es una vasculitis poco frecuente que puede manifestarse con síntomas intestinales, como en este caso; es importante tenerlo en mente a la hora de los diagnósticos diferenciales. Existen pocos reportes con este síndrome asociado con abdomen agudo, todos ellos con mal pronóstico.

  8. Abdominal Pain: A Comparison between Neurogenic Bowel Dysfunction and Chronic Idiopathic Constipation

    Directory of Open Access Journals (Sweden)

    Pia Møller Faaborg


    Full Text Available Introduction. Most spinal-cord-injured patients have constipation. One-third develop chronic abdominal pain 10 years or more after injury. Nevertheless, very little is known about the nature of abdominal pain after spinal cord injury (SCI. It may be neuropathic or caused by constipation. Aim. To compare characteristics of abdominal pain in SCI with able-bodied with chronic idiopathic constipation (CIC. Subjects and Methods. 21 SCI and 15 CIC patients were referred for treatment of bowel symptoms. Constipation-related symptoms were assessed with the Cleveland Constipation Scoring System and the International Spinal Cord Injury Basic Bowel Function Data Set. Characteristics of abdominal pain were described using the Brief Danish Pain Questionnaire. Total gastrointestinal transit times (GITT were measured by radiopaque markers. Results. Seventeen (81% SCI and 14 (93% CIC patients reported abdominal pain or discomfort within the last month (. Pain was considered more intense by CIC than by SCI patients (. Only minor differences were found in patient’s qualitative description of abdominal pain or in the location of pain. In neither SCI nor CIC was pain associated with GITT. Conclusion. Most characteristics of abdominal pain among SCI patients resemble those of CIC. This indicates that constipation is a major cause of pain after SCI.

  9. Abdominal binders may reduce pain and improve physical function after major abdominal surgery - a systematic review

    DEFF Research Database (Denmark)

    Rothman, Josephine Philip; Gunnarsson, Ulf; Bisgaard, Thue


    INTRODUCTION: Evidence for the effect of post-operative abdominal binders on post-operative pain, seroma formation, physical function, pulmonary function and increased intra-abdominal pressure among patients after surgery remains largely un-investigated. METHODS: A systematic review was conducted....... The PubMed, EMBASE and Cochrane databases were searched for studies on the use of abdominal binders after abdominal surgery or abdominoplasty. All types of clinical studies were included. Two independent assessors evaluated the scientific quality of the studies. The primary outcomes were pain, seroma...... to reduce seroma formation after laparoscopic ventral herniotomy and a non-significant reduction in pain. Physical function was improved, whereas evidence supports a beneficial effect on psychological distress after open abdominal surgery. Evidence also supports that intra-abdominal pressure increases...

  10. Optimal control applied to a thoraco-abdominal CPR model. (United States)

    Jung, Eunok; Lenhart, Suzanne; Protopopescu, Vladimir; Babbs, Charles


    The techniques of optimal control are applied to a validated blood circulation model of cardiopulmonary resuscitation (CPR), consisting of a system of seven difference equations. In this system, the non-homogeneous forcing terms are chest and abdominal pressures acting as the 'controls'. We seek to maximize the blood flow, as measured by the pressure difference between the thoracic aorta and the right atrium. By applying optimal control methods, we characterize the optimal waveforms for external chest and abdominal compression during cardiac arrest and CPR in terms of the solutions of the circulation model and of the corresponding adjoint system. Numerical results are given for various scenarios. The optimal waveforms confirm the previously discovered positive effects of active decompression and interposed abdominal compression. These waveforms can be implemented with manual (Lifestick-like) and mechanical (vest-like) devices to achieve levels of blood flow substantially higher than those provided by standard CPR, a technique which, despite its long history, is far from optimal.

  11. Estimated Probability of Traumatic Abdominal Injury During an International Space Station Mission (United States)

    Lewandowski, Beth E.; Brooker, John E.; Weavr, Aaron S.; Myers, Jerry G., Jr.; McRae, Michael P.


    The Integrated Medical Model (IMM) is a decision support tool that is useful to spaceflight mission planners and medical system designers when assessing risks and optimizing medical systems. The IMM project maintains a database of medical conditions that could occur during a spaceflight. The IMM project is in the process of assigning an incidence rate, the associated functional impairment, and a best and a worst case end state for each condition. The purpose of this work was to develop the IMM Abdominal Injury Module (AIM). The AIM calculates an incidence rate of traumatic abdominal injury per person-year of spaceflight on the International Space Station (ISS). The AIM was built so that the probability of traumatic abdominal injury during one year on ISS could be predicted. This result will be incorporated into the IMM Abdominal Injury Clinical Finding Form and used within the parent IMM model.

  12. Percutaneous Zenith endografting for abdominal aortic aneurysms. (United States)

    Heyer, Kamaldeep S; Resnick, Scott A; Matsumura, Jon S; Amaranto, Daniel; Eskandari, Mark K


    A completely percutaneous approach to infrarenal abdominal aortic aneurysm (AAA) endografting has the theoretic benefits of being minimally invasive and more expedient. Our goal was to demonstrate the utility of this approach using a suprarenal fixation device and a suture-mediated closure system. We conducted a single-institution, retrospective review of 14 patients who underwent percutaneous AAA repair with the Zenith device between August 2003 and March 2007. Immediate and delayed access-related outcomes were examined over a mean follow-up of 12.1+/-2.0 months. Mean AAA size was 5.6 cm. Immediate arterial closure and technical success rate was 96% (27/28 vessels). One immediate hemostatic failure required open surgical repair. Over follow-up, one vessel required operative repair for new-onset claudication. No other immediate or delayed complications (thrombosis, pseudoaneurysm, infection, or deep venous thrombosis) were detected. A percutaneous approach for the treatment of AAA has several advantages over femoral artery cutdown but also has its own unique set of risks in the immediate and late postoperative period. Ultimately, the "preclose technique" can be safely applied for the Zenith device despite its large-bore delivery system.

  13. [Inflammatory aneurysms of the abdominal aorta]. (United States)

    Tovar Martín, E; Acea Nebril, B


    Approximately 10 per cent of abdominal aneurysms have an excessively thick wall that sometimes involve duodenum, cava or colon by an inflammatory process. Between February 1986 and December 1992, 147 patients with abdominal aortic aneurysm (AAA) were treated surgically and in 13 (8.8%) the aneurysms were found to be inflammatory. Their mean age was 67.3 years (70.1 years in non inflammatory group) and all were symptomatics initially (abdominal pain in 53%, rupture in 23%, mass in 15%). The operative mortality for elective resection was 37% in patients with inflammatory abdominal aortic aneurysms (IAAA) decreasing to 9% in the AAA group without inflammatory involvement. We conclude that surgery is indicated in these patients to prevent rupture and to hasten the subsidense of inflammatory process ever with postoperative morbi-mortality increased.

  16. Abdominal Wall Hernias: Various Imaging Features Correlated with the Anatomy of Abdominal Wall at MDCT

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Shin Young; Shin, Hyeong Cheol; Kim, Sang Won; Kim, Il Young; Kim, Young Tong [Soonchunhyang University Cheonan Hospital, Cheonan (Korea, Republic of)


    Abdominal wall hernias are a common condition. However, they may develop acute complications and require surgical correction in most cases. Hence, the correct radiological examination is requisite for an accurate diagnosis. A multi-detector row CT (MDCT) provides an accurate identification of the anatomy of the abdominal wall, precise hernia type, and helps in the detection of early signs of complication. We report various imaging features of abdominal wall hernias via a MDCT.

  17. Dynamic changes in thrombin generation in abdominal sepsis in mice. (United States)

    Wang, Yongzhi; Braun, Oscar O; Zhang, Su; Luo, Lingtao; Norström, Eva; Thorlacius, Henrik


    Systemic inflammatory response syndrome and severe infections are associated with major derangements in the coagulation system. The purpose of this study was to examine the dynamic alterations in thrombin generation in abdominal sepsis. Abdominal sepsis was induced by cecal ligation and puncture (CLP) in C57/Bl6 mice. Cecal ligation and puncture caused a systemic inflammatory response, with neutrophil recruitment and tissue damage in the lung as well as thrombocytopenia and leukocytopenia. Thrombin generation, coagulation factors, lung histology, and myeloperoxidase activity was determined 1, 3, 6, and 24 h after induction of CLP. It was found that thrombin generation was increased 1 h after CLP and that thrombin generation started to decrease at 3 h and was markedly reduced 6 and 24 h after CLP induction. Platelet-poor plasma from healthy mice could completely reverse the inhibitory effect of CLP on thrombin generation, suggesting that sepsis caused a decrease in the levels of plasma factors regulating thrombin generation in septic animals. Indeed, it was found that CLP markedly decreased plasma levels of prothrombin, factor V, and factor X at 6 and 24 h. Moreover, we observed that CLP increased plasma levels of activated protein C at 6 h, which returned to baseline levels 24 h after CLP induction. Finally, pretreatment with imipenem/cilastatin attenuated the CLP-evoked decrease in thrombin generation and consumption of prothrombin 24 h after CLP induction. Our novel findings suggest that thrombin generation is initially increased and later decreased in abdominal sepsis. Sepsis-induced reduction in thrombin generation is correlated to changes in the plasma levels of coagulation factors and activated protein C. These findings help explain the dynamic changes in global hemostasis in abdominal sepsis.

  18. A focus on intra-abdominal infections

    Directory of Open Access Journals (Sweden)

    Sartelli Massimo


    Full Text Available Abstract Complicated intra-abdominal infections are an important cause of morbidity and are frequently associated with poor prognosis, particularly in higher risk patients. Well defined evidence-based recommendations for intra-abdominal infections treatment are partially lacking because of the limited number of randomized-controlled trials. Factors consistently associated with poor outcomes in patients with intra-abdominal infections include increased illness severity, failed source control, inadequate empiric antimicrobial therapy and healthcare-acquired infection. Early prognostic evaluation of complicated intra-abdominal infections is important to select high-risk patients for more aggressive therapeutic procedures. The cornerstones in the management of complicated intra-abdominal infections are both source control and antibiotic therapy. The timing and the adequacy of source control are the most important issues in the management of intra-abdominal infections, because inadequate and late control of septic source may have a negative effect on the outcomes. Recent advances in interventional and more aggressive techniques could significantly decrease the morbidity and mortality of physiologically severe complicated intra-abdominal infections, even if these are still being debated and are yet not validated by limited prospective trials. Empiric antimicrobial therapy is nevertheless important in the overall management of intra-abdominal infections. Inappropriate antibiotic therapy may result in poor patient outcomes and in the appearance of bacterial resistance. Antimicrobial management is generally standardised and many regimens, either with monotherapy or combination therapy, have proven their efficacy. Routine coverage especially against Enterococci and candida spp is not always recommended, but can be useful in particular clinical conditions. A de escalation approach may be recommended in patients with specific risk factors for multidrug

  1. Hérnia traumática da parede abdominal Traumatic abdominal hernia

    Directory of Open Access Journals (Sweden)

    Alexandre Cruz Henriques


    Full Text Available A rare case of blunt traumatic abdominal hernia is presented in which jejunal loops herniated through the abdominal wall. The patient had a serious motor vehicle accident seven years ago, while wearing the seat belt. He developed a traumatic hernia in the anterior lateral abdominal wall, which was operated, and relapsed after some months. The patient was reoperated and we observed the unattachment of the anterior lateral abdominal musculature from the ilium crest. After the hernial sac treatment, the defect was solved with the use of a polypropylene mesh. The postoperative evolution was good and four months later there were no signs of recurrence. Traumatic abdominal hernia remains a rare clinical entity, despite the increase in blunt abdominal trauma. Traumatic abdominal wall hernia falls into two general categories: small lower quadrant abdominal defects, typically the result of blunt trauma with bicycle handlebars, and larger abdominal wall defects related to motor vehicle accidents. The diagnosis may be often established by the physical examination alone. Conventional radiology and computerized tomography usefulness have been proved. In the vast majority of cases, early repair is recommended. The appropriate treatment is the reduction of the herniated bowel into the abdomen, the debridment of nonviable tissues, and a primary tension free closure of the detect.

  2. Abdominal epilepsy and foreign body in the abdomen--dilemma in diagnosis of abdominal pain. (United States)

    Topno, Noor; Gopasetty, Mahesh S; Kudva, Annappa; B, Lokesh


    There are many medical causes of abdominal pain; abdominal epilepsy is one of the rarer causes. It is a form of temporal lobe epilepsy presenting with abdominal aura. Temporal lobe epilepsy is often idiopathic, however it may be associated with mesial temporal lobe sclerosis, dysembryoplastic neuroepithelial tumors and other benign tumors, arterio-venous malformations, gliomas, neuronal migration defects or gliotic damage as a result of encephalitis. When associated with anatomical abnormality, abdominal epilepsy is difficult to control with medication alone. In such cases, appropriate neurosurgery can provide a cure or, at least, make this condition easier to treat with medication. Once all known intra-abdominal causes have been ruled out, many cases of abdominal pain are dubbed as functional. If clinicians are not aware of abdominal epilepsy, this diagnosis is easily missed, resulting in inappropriate treatment. We present a case report of a middle aged woman presenting with abdominal pain and episodes of unconsciousness. On evaluation she was found to have an intra-abdominal foreign body (needle). Nevertheless, the presence of this entity was insufficient to explain her episodes of unconsciousness. On detailed analysis of her medical history and after appropriate investigations, she was diagnosed with temporal lobe epilepsy which was treated with appropriate medications, and which resulted in her pain being relieved.

  5. Mechanical Intestinal Obstruction in a Porcine Model: Effects of Intra-Abdominal Hypertension. A Preliminary Study.

    Directory of Open Access Journals (Sweden)

    L Correa-Martín

    Full Text Available Mechanical intestinal obstruction is a disorder associated with intra-abdominal hypertension and abdominal compartment syndrome. As the large intestine intraluminal and intra-abdominal pressures are increased, so the patient's risk for intestinal ischaemia. Previous studies have focused on hypoperfusion and bacterial translocation without considering the concomitant effect of intra-abdominal hypertension. The objective of this study was to design and evaluate a mechanical intestinal obstruction model in pigs similar to the human pathophysiology.Fifteen pigs were divided into three groups: a control group (n = 5 and two groups of 5 pigs with intra-abdominal hypertension induced by mechanical intestinal obstruction. The intra-abdominal pressures of 20 mmHg were maintained for 2 and 5 hours respectively. Hemodynamic, respiratory and gastric intramucosal pH values, as well as blood tests were recorded every 30 min.Significant differences between the control and mechanical intestinal obstruction groups were noted. The mean arterial pressure, cardiac index, dynamic pulmonary compliance and abdominal perfusion pressure decreased. The systemic vascular resistance index, central venous pressure, pulse pressure variation, airway resistance and lactate increased within 2 hours from starting intra-abdominal hypertension (p<0.05. In addition, we observed increased values for the peak and plateau airway pressures, and low values of gastric intramucosal pH in the mechanical intestinal obstruction groups that were significant after 3 hours.The mechanical intestinal obstruction model appears to adequately simulate the pathophysiology of intestinal obstruction that occurs in humans. Monitoring abdominal perfusion pressure, dynamic pulmonary compliance, gastric intramucosal pH and lactate values may provide insight in predicting the effects on endorgan function in patients with mechanical intestinal obstruction.

  6. Pathogenesis of Intra-abdominal and pelvic adhesion development. (United States)

    Imudia, Anthony N; Kumar, Sanjeev; Saed, Ghassan M; Diamond, Michael P


    Abdominal and pelvic adhesions are a frequent occurrence and are responsible for significant morbidity resulting in abdominal and pelvic pain, infertility, and small bowel obstruction. The process of adhesion development begins when damage to peritoneal surfaces from any source (operative trauma, infection, foreign bodies, desiccation, irradiation, allergic reaction, or chemical injury) induces a series of biochemical/molecular biologic cascades involving different elements. These elements include peritoneal fluid, neutrophils, leukocytes, macrophages, cytokines, mesothelial cells, and tissue and coagulation factors, which teleologically have the intention of peritoneal repair; however, these processes also result in adhesion development. Major pathways that play significant roles in the healing process of peritoneal damage leading to adhesion development are the fibrinolytic system, extracellular matrix deposition, growth factor and cytokines, cell adhesion molecules, angiogenesis, apoptosis and proliferation, and remesothelialization. Greater understanding of the regulation and interaction of these processes provides the potential for reduction of postoperative adhesion development.

    Sanjay Kumar Mandal; Partha Pratim Chakraborty; Rana Bhattacharjee; Subhasis Roy Chowdhury; Shounak Majumdar


    A middle aged, non-addict male presented with right upper abdominal pain and swelling with respiratory distress. Examination revealed central cyanosis, bipedal pitting edema with prominentepigastric and back veins.Liver was enlarged, tender, spanned 20 cm without any splenomegaly or ascites. Other systems were clinically normal. Laboratory investigations showed polymorphonuclear leucocytosis with slightly deranged liver function. Abdominal ultrasonography showed an abscess in the right lobe of the liver with compressed inferior vena cava (IVC), middle and left hepatic veins.Arterial blood gas (ABG) documented hypoxia with orthodeoxia and air-contrast echocardiography was suggestive of an intrapulmonary shunt. A diagnosis of hepato-pulmonary syndrome (HPS) was made with near normal liver function secondary to amebic liver abscess.It reversed completely following successful treatment of the liver abscess.

  8. Osteoprotegerin Prevents Development of Abdominal Aortic Aneurysms.

    Directory of Open Access Journals (Sweden)

    Batmunkh Bumdelger

    Full Text Available Abdominal aortic aneurysms (AAAs, which commonly occur among elderly individuals, are accompanied by a risk of rupture and subsequent high mortality. Establishment of medical therapies for the prevention of AAAs requires further understanding of the molecular pathogenesis of this condition. This report details the possible involvement of Osteoprotegerin (OPG in the prevention of AAAs through inhibition of Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL. In CaCl2-induced AAA models, both internal and external diameters were significantly increased with destruction of elastic fibers in the media in Opg knockout (KO mice, as compared to wild-type mice. Moreover, up-regulation of TRAIL expression was observed in the media by immunohistochemical analyses. Using a culture system, both the TRAIL-induced expression of matrix metalloproteinase-9 in smooth muscle cells (SMCs and the chemoattractive effect of TRAIL on SMCs were inhibited by OPG. These data suggest that Opg may play a preventive role in the development of AAA through its antagonistic effect on Trail.

  10. Implanting intra-abdominal radiotransmitters with external whip antennas in ducks (United States)

    Korschgen, C.E.; Kenow, K.P.; Gendron-Fitzpatrick, A.; Green, W.L.; Dein, F.J.


    We developed and evaluated a surgical procedure for implanting intra-abdominal radiotransmitters with external whip antennas in captive mallards (Anas platyrhynchos). Transmitters were implanted in the abdominal cavity and the antennas exited through the caudal abdominal wall and skin. Birds with implanted transmitters developed mild to moderate localized air sac reactions. These reactions involved adhesions of the right anterior abdominal air sac to the liver with contractions around the transmitters and antenna catheters. The adhesions were reinforced by a proliferation of connective tissue and lined by multinucleated giant cells (foreign body reaction). Casual observation indicated that neither behavior nor activity of the birds was altered by the histological reaction to the transmitter implant. No increase in systemic lesions (particularly liver or kidney) could be correlated with the histological reactions. Our evaluations indicate that the procedure is a reliable method for radiomarking ducks and the technique has been successfully used in 2 field studies.

  11. Lower respiratory tract infection and rapid expansion of an abdominal aortic aneurysm: a case report

    Directory of Open Access Journals (Sweden)

    Puppala Sapna


    Full Text Available Abstract Introduction The rate of abdominal aortic aneurysm expansion is related to multiple factors. There is some evidence that inflammation can accelerate aneurysm expansion. However, the association between pulmonary sepsis and rapid abdominal aortic aneurysm expansion is rarely reported. Case presentation Here we present a case of a rapidly expanding abdominal aortic aneurysm in a 68-year-old Caucasian man with a concomitant lower respiratory tract infection and systemic sepsis requiring intensive monitoring and urgent endovascular intervention. Our patient had an uncomplicated post-operative recovery and a follow-up computed tomography scan at one month demonstrated no evidence of an endoleak. Conclusion This case highlights the potential association between pulmonary sepsis and rapid abdominal aortic aneurysm expansion. In such cases, a policy of frequent monitoring should be adopted to identify those patients requiring definitive management.

    Intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) have shown clinical relevance in monitoring critically ill human beings submitted to abdominal surgery. Only a few studies have been performed in veterinary medicine. The aim of this study was to assess how pregnancy and abdominal surgery may affect IAP and APP in healthy cats. For this purpose, pregnant (n=10) and non-pregnant (n=11) queens undergoing elective spaying, and tomcats (n=20, used as controls) presented for neutering by scrotal orchidectomy were included in the study. IAP, mean arterial blood pressure (MAP), APP, heart rate and rectal temperature (RT) were determined before, immediately after, and four hours after surgery.

    Milanesi, Rafaela; Caregnato, Rita Catalina Aquino


    There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 2012. Twenty articles were identified, in that, 12 literature reviews, 4 descriptive and exploratory studies, 2 expert opinions, one prospective cohort study and one was an experience report. The vesical intra-abdominal pressure measurement was considered gold standard. There are variations in the technique however, but some common points were identified: complete supine position, in absence of abdominal contracture, in the end of expiration and expressed in mmHg. Most research results indicate keeping the transducer zeroed at the level of the mid-axillary line at the iliac crest level, and instill 25mL of sterile saline. Strong evidence must be developed.

    Li Shao

    Full Text Available BACKGROUND: Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS: Patients (n = 160 scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients' nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. RESULTS: When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. DISCUSSION: The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed.

  20. Imaging the Abdominal Manifestations of Cystic Fibrosis

    C. D. Gillespie


    Full Text Available Cystic fibrosis (CF is a multisystem disease with a range of abdominal manifestations including those involving the liver, pancreas, and kidneys. Recent advances in management of the respiratory complications of the disease has led to a greater life expectancy in patients with CF. Subsequently, there is increasing focus on the impact of abdominal disease on quality of life and survival. Liver cirrhosis is the most important extrapulmonary cause of death in CF, yet significant challenges remain in the diagnosis of CF related liver disease. The capacity to predict those patients at risk of developing cirrhosis remains a significant challenge. We review representative abdominal imaging findings in patients with CF selected from the records of two academic health centres, with a view to increasing familiarity with the abdominal manifestations of the disease. We review their presentation and expected imaging findings, with a focus on the challenges facing diagnosis of the hepatic manifestations of the disease. An increased familiarity with these abdominal manifestations will facilitate timely diagnosis and management, which is paramount to further improving outcomes for patients with cystic fibrosis.

    AIM: To study the morphologic and cellular immunologic changes after homologous transplantation of the abdominal aorta in rats after programmed cryopreservation (-196°C).METHODS: Abdominal aorta was harvested from anesthetized Spraque Dawley (SD) rats for cryopreservation (group B) or immediate implantation (group A). The survival rates and apoptotic rates of aortic endothelial cells (ECs)were examined. The patency rates, histology and cellular immunologic changes of the abdominal aorta were examined on days 1, 3, 7, 14, 30, 60 after transplantation respectively.RESULTS: The survival rate of ECs after programmed cryopreservation was 90.1±1.79%, about 3.4% lower than that of uncryopreservation (93.5±1.96%). The apoptotic rates of ECs was increased after cryopreservation (7.15%vs 4.86%, P<0.05). The patency rate of group B was significantly higher than that of group A (91.6±12.9% vs 62.5±26.2%, P<0.01). CD4/CD8 ratio, TCR αβ and CD11b/CD18 ratio of group B were significantly lower than those of group A (P<0.05). Revivification of the cryopreserved abdominal aorta showed normal adventitia and intact smooth muscle cells.CONCLUSION: Cryopreservation can reduce homologous abdominal aortic antigenecity. Even if without administration of immunosuppressive agents, it is still feasible to implement homologous artery grafting in rats.

    Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

  3. Transverse abdominal plane neurostimulation for chronic abdominal pain: a novel technique. (United States)

    Gupta, Mayank; Goodson, Robert


    Management of chronic abdominal pain can be challenging. Sometimes patients fail to get adequate response from multiple medications and nerve blocks. We present a patient case report of chronic abdominal pain with a history of multiple surgeries managed successfully by neuromodulation of the transverse abdominis plane (TAP). The TAP block is a procedure in which local anesthetic is injected into the abdominal fascial plane that carries sensory nerves to the abdominal wall in order to block pain sensation. It has been shown to reduce postoperative pain and analgesic dependence after abdominal and gynecological surgeries. A 60-year-old woman presented to us for chronic abdominal pain for which medications provided little relief. She had an extensive history of abdominal surgeries and was also treated for lower back pain with surgery and less invasive procedures in the past. Under our care, she underwent 2 TAP blocks with almost complete resolution of her abdominal pain. Her pain, however, came back within a few of weeks of the procedures. Since our patient found pain relief from the TAP blocks, we proceeded with neurostimulation of the TAP for long-term pain relief. We placed a dorsal column stimulator 16 contact lead for lower back and leg pain and 8 contact leads placed in the TAP under ultrasound guidance. She has had multiple follow-ups since her TAP lead placement procedure with continued and near complete resolution of her abdominal pain. The TAP lead stimulation was helping her abdominal pain and the dorsal column lead stimulation was helping her back and leg pain.

    Roberta Fernandes Bonfim


    Full Text Available OBJECTIVE: To study the effect of hemodialysis on intra-abdominal pressure. METHODS: Five patients admitted between July and November of 2003 were evaluated in the intensive care unit. Intra-abdominal pressure was measured before and after hemodialysis, maintaining the ventilatory parameters except for PEEP (positive-end expiratory pressure. RESULTS: Intra-abdominal pressure was significantly reduced by hemodialysis in all the 5 patients. CONCLUSION: Hemodialysis significantly reduced intra-abdominal pressure in the 5 patients, an effect which could have influence over other organic systems. This reduction is related to the weight variation before and after hemodialysis, as well as to the loss of volume caused by this procedure.OBJETIVO: Pesquisar o efeito da hemodiálise sobre a pressão intra-abdominal. MÉTODOS: Foram avaliados cinco pacientes internados entre julho e novembro de 2003, na Unidade de Terapia Intensiva do Serviço de Nefrologia do Hospital das Clínicas de São Paulo. Mensurou-se a pressão intra-abdominal antes e após a hemodiálise, mantendo os parâmetros ventilatórios exceto a PEEP (positive end expiratory pressure. RESULTADOS: Constatou-se que a hemodiálise foi capaz de reduzir significativamente a PIA em cinco pacientes na Unidade de Terapia Intensiva CONCLUSÃO: A hemodiálise reduziu a pressão intra-abdominal numa amostra de cinco pacientes, de maneira significativa, o que poderia influenciar os demais sistemas orgânicos. Essa redução está relacionada com a variação de peso pré e pós-hemodiálise, e com a perda de volume promovida pelo procedimento.

  5. Abdominal Wall Endometrioma. Report of Two Cases

    Directory of Open Access Journals (Sweden)

    Tahiluma Santana Pedraza


    Full Text Available Abdominal wall endometrioma is a condition rarely seen by surgeons. It represents a diagnostic challenge due to its similarity with other tumors. This entity occurs in fertile women and often appears two to five years after gynecological and obstetric surgical procedures. It must be considered when dealing with a cyclically painful nodule located in a laparotomy scar. The diagnosis is established by histological examination; most imaging tests determine the characteristics of the lesion, concomitant lesions and the intra-abdominal origin or location in the abdominal wall. The cases of two patients treated at the General Surgery Department of the María Eugenia González Comprehensive Diagnostic Center in the Capital District, Venezuela, are presented. Wide excision of the tissue and histological examination were performed, confirming the diagnosis. The postoperative course was uneventful. This case is presented given the rarity of this condition.

  6. Electromyographic analysis of four popular abdominal exercises. (United States)

    Piering, A W; Janowski, A P; Wehrenberg, W B; Moore, M T; Snyder, A C


    This study was designed to evaluate the effects of four specific sit-up exercises on muscular activity of the rectus abdominis. Pairs of surface electrodes were placed unilaterally on four quadrants of the rectus abdominis, delimited by tendinous inscriptions, in four male subjects. Electromyographic (EMG) recordings were taken while the subjects performed four different abdominal exercises. Each abdominal exercise was hypothesized to have a specific effect on one of the four quadrants of the rectus abdominis. The four exercises analyzed were: 1) long lying crunch, 2) bent knee crunch, 3) leg raise, and 4) vertical leg crunch. Analysis of the standardized EMG recordings demonstrated no significant differences in the mean muscle activity between the four different quadrants, in the mean muscle activity between the four different exercises, and in interactions between the exercises and the quadrants of the rectus abdominis. We conclude that none of the four abdominal exercises studied are specific for strengthening individual muscle quadrants of the rectus abdominis.

  7. Abdominal Wall Desmoid during Pregnancy: Diagnostic Challenges

    Directory of Open Access Journals (Sweden)

    Johnny Awwad


    Full Text Available Background. Desmoids are benign tumors, with local invasive features and no metastatic potential, which have rarely been described to be pregnancy associated. Case. We described the rapid growth of an anterior abdominal wall mass in a 40-year-old pregnant woman. Due to its close proximity to the enlarged uterus, it was misdiagnosed to be a uterine leiomyoma by ultrasound examination. Final tissue diagnosis and radical resection were done at the time of abdominal delivery. Conclusion. Due to the diagnostic limitations of imaging techniques, desmoids should always be considered when the following manifestations are observed in combination: progressive growth of a solitary abdominal wall mass during pregnancy and well-delineated smooth tumor margins demonstrated by imaging techniques. This case emphasizes the importance of entertaining uncommon medical conditions in the differential diagnosis of seemingly common clinical manifestations.

  8. Decompressive laparotomy for abdominal compartment syndrome (United States)

    Kimball, E.; Malbrain, M.; Nesbitt, I.; Cohen, J.; Kaloiani, V.; Ivatury, R.; Mone, M.; Debergh, D.; Björck, M.


    Background The effect of decompressive laparotomy on outcomes in patients with abdominal compartment syndrome has been poorly investigated. The aim of this prospective cohort study was to describe the effect of decompressive laparotomy for abdominal compartment syndrome on organ function and outcomes. Methods This was a prospective cohort study in adult patients who underwent decompressive laparotomy for abdominal compartment syndrome. The primary endpoints were 28‐day and 1‐year all‐cause mortality. Changes in intra‐abdominal pressure (IAP) and organ function, and laparotomy‐related morbidity were secondary endpoints. Results Thirty‐three patients were included in the study (20 men). Twenty‐seven patients were surgical admissions treated for abdominal conditions. The median (i.q.r.) Acute Physiology And Chronic Health Evaluation (APACHE) II score was 26 (20–32). Median IAP was 23 (21–27) mmHg before decompressive laparotomy, decreasing to 12 (9–15), 13 (8–17), 12 (9–15) and 12 (9–14) mmHg after 2, 6, 24 and 72 h. Decompressive laparotomy significantly improved oxygenation and urinary output. Survivors showed improvement in organ function scores, but non‐survivors did not. Fourteen complications related to the procedure developed in eight of the 33 patients. The abdomen could be closed primarily in 18 patients. The overall 28‐day mortality rate was 36 per cent (12 of 33), which increased to 55 per cent (18 patients) at 1 year. Non‐survivors were no different from survivors, except that they tended to be older and on mechanical ventilation. Conclusion Decompressive laparotomy reduced IAP and had an immediate effect on organ function. It should be considered in patients with abdominal compartment syndrome. PMID:26891380

  9. Abdominal Pain: A Comparison between Neurogenic Bowel Dysfunction and Chronic Idiopathic Constipation (United States)

    Finnerup, Nanna Brix; Christensen, Peter


    Introduction. Most spinal-cord-injured patients have constipation. One-third develop chronic abdominal pain 10 years or more after injury. Nevertheless, very little is known about the nature of abdominal pain after spinal cord injury (SCI). It may be neuropathic or caused by constipation. Aim. To compare characteristics of abdominal pain in SCI with able-bodied with chronic idiopathic constipation (CIC). Subjects and Methods. 21 SCI and 15 CIC patients were referred for treatment of bowel symptoms. Constipation-related symptoms were assessed with the Cleveland Constipation Scoring System and the International Spinal Cord Injury Basic Bowel Function Data Set. Characteristics of abdominal pain were described using the Brief Danish Pain Questionnaire. Total gastrointestinal transit times (GITT) were measured by radiopaque markers. Results. Seventeen (81%) SCI and 14 (93%) CIC patients reported abdominal pain or discomfort within the last month (P = 0.38). Pain was considered more intense by CIC than by SCI patients (P GITT. Conclusion. Most characteristics of abdominal pain among SCI patients resemble those of CIC. This indicates that constipation is a major cause of pain after SCI. PMID:24159329

    Ameh, E A; Nmadu, P T


    This is a report of a retrospective study of 24 children managed for penetrating abdominal injury over 10 years, and it represents 34% of all abdominal injuries in children in that period. Falls onto sharp objects within and around the home were responsible for ten of the injuries, seven were injured by animal horns and four were sporting injuries. Violence and road traffic accidents were uncommon. Most patients (67%) had evisceration of omentum or intestine, and one of these was found at laparotomy to have a jejuno-jejunal intussusception. Seven children had injury to hollow viscera. There were three deaths, one each from overwhelming sepsis, tetanus and haemorrhage.

  12. Thrombin generation in abdominal sepsis is Rho-kinase-dependent. (United States)

    Wang, Yongzhi; Braun, Oscar Ö; Zhang, Su; Norström, Eva; Thorlacius, Henrik


    Sepsis causes severe derangements of the coagulation system. However, the signaling mechanisms regulating sepsis-induced thrombin generation remain elusive. Herein, we hypothesized that Rho-kinase might be an important regulator of thrombin generation in abdominal sepsis. Abdominal sepsis was induced by cecal ligation and puncture (CLP) in C57Bl/6 mice. Thrombin generation, coagulation factors, lung histology and myeloperoxidase (MPO) activity were determined 6 h and 24 h after induction of CLP. Induction of CLP triggered a systemic inflammatory response characterized by neutrophil accumulation and tissue injury in the lung as well as thrombocytopenia and leukocytopenia. Administration of Y-27632, a Rho-kinase inhibitor, attenuated these markers of systemic inflammation in CLP animals. Moreover, peak thrombin formation was decreased by 77% and 81% in plasma from mice 6 h and 24 h after induction of CLP. Total thrombin generation was reduced by 64% and 67% 6 h and 24 h after CLP induction, respectively. Notably, administration of Y-27632 increased peak formation by 99% and total thrombin generation by 66% in plasma from septic animals. In addition, CLP markedly decreased plasma levels of prothrombin, factor V and factor X at 6 h and 24 h. Interestingly, Rho-kinase inhibition significantly enhanced levels of prothrombin, factor V and factor X in plasma from septic mice. In addition, inhibition of Rho-kinase decreased CLP-induced elevations of CXCL2 by 36% and interleukin-6 by 38%. These novel findings suggest that sepsis-induced thrombin generation is regulated by Rho-kinase. Moreover, inhibition of Rho-kinase reverses sepsis-evoked consumption of coagulation factors. Thus, our results show that targeting Rho-kinase signaling might protect against coagulation dysfunction in abdominal sepsis.

    Powell; Joseph


    Objective: A retrospective study to determine the success and complications of abdominal sacral colpopexy in correcting massive genital prolapse over an 8-year period between September 1989 and January 1997.Methods: The charts were reviewed for 3 patients with massive procidentia and 15 patients with symptomatic posthysterectomy vaginal vault prolapse, who desired preservation of sexual function and underwent abdominal sacral colpopexy with Marlex mesh at two community teaching hospitals.Results: In 16 of the 18 patients, one or more concurrent procedures were performed at the same time, including three Burch colpocystourethropexies and one Raz bladder neck suspension, which successfully controlled urinary stress incontinence. In three cases, staging procedures were done for ovarian neoplasia. There were no intraoperative complications. One patient developed a superficial abdominal wound infection, one patient had a deep venous thrombosis in her left leg 7 days postoperatively, and one patient experienced a 1 cm area of graft erosion 10 months postoperative requiring partial resection. Duration of follow-up has varied from 8 months to 5 years. One patient died 43 months after surgery of unrelated causes. No patients developed recurrent prolapse.Conclusions: Abdominal sacral colpopexy is a successful operation for the correction of prolapse. Serious complications are infrequent. Photographs of the technique and a review of the literature are presented.

  7. Biomechanical considerations for abdominal loading by seat belt pretensioners. (United States)

    Rouhana, Stephen W; El-Jawahri, Raed E; Laituri, Tony R


    While seat belts are the most effective safety technology in vehicles today, there are continual efforts in the industry to improve their ability to reduce the risk of injury. In this paper, seat belt pretensioners and current trends towards more powerful systems were reviewed and analyzed. These more powerful systems may be, among other things, systems that develop higher belt forces, systems that remove slack from belt webbing at higher retraction speeds, or both. The analysis started with validation of the Ford Human Body Finite Element Model for use in evaluation of abdominal belt loading by pretensioners. The model was then used to show that those studies, done with lap-only belts, can be used to establish injury metrics for tests done with lap-shoulder belts. Then, previously-performed PMHS studies were used to develop AIS 2+ and AIS 3+ injury risk curves for abdominal interaction with seat belts via logistic regression and reliability analysis with interval censoring. Finally, some considerations were developed for a possible laboratory test to evaluate higher-powered pretensioners.

  8. Electromagnetic tracking for abdominal interventions in computer aided surgery. (United States)

    Zhang, Hui; Banovac, Filip; Lin, Ralph; Glossop, Neil; Wood, Bradford J; Lindisch, David; Levy, Elliot; Cleary, Kevin


    Electromagnetic tracking has great potential for assisting physicians in precision placement of instruments during minimally invasive interventions in the abdomen, since electromagnetic tracking is not limited by the line-of-sight restrictions of optical tracking. A new generation of electromagnetic tracking has recently become available, with sensors small enough to be included in the tips of instruments. To fully exploit the potential of this technology, our research group has been developing a computer aided, image-guided system that uses electromagnetic tracking for visualization of the internal anatomy during abdominal interventions. As registration is a critical component in developing an accurate image-guided system, we present three registration techniques: 1) enhanced paired-point registration (time-stamp match registration and dynamic registration); 2) orientation-based registration; and 3) needle shape-based registration. Respiration compensation is another important issue, particularly in the abdomen, where respiratory motion can make precise targeting difficult. To address this problem, we propose reference tracking and affine transformation methods. Finally, we present our prototype navigation system, which integrates the registration, segmentation, path-planning and navigation functions to provide real-time image guidance in the clinical environment. The methods presented here have been tested with a respiratory phantom specially designed by our group and in swine animal studies under approved protocols. Based on these tests, we conclude that our system can provide quick and accurate localization of tracked instruments in abdominal interventions, and that it offers a user-friendly display for the physician.

  9. Complex pathologies of angiotensin Ⅱ-induced abdominal aortic aneurysms

    Institute of Scientific and Technical Information of China (English)

    Alan DAUGHERTY; Lisa A. CASSIS; Hong LU


    Angiotensin Ⅱ (Angll) is the primary bioactive peptide of the renin angiotensin system that plays a critical role in many cardiovascular diseases.Subcutaneous infusion of Angll into mice induces the development of abdominal aortic aneurysms (AAAs).Like human AAAs,Angll-induced AAA tissues exhibit progressive changes and considerable heterogeneity.This complex pathology provides an impediment to the quantification of aneurysmal tissue composition by biochemical and immunostaining techniques.Therefore,while the mouse model of Angll-induced AAAs provides a salutary approach to studying the mechanisms of the evolution of AAAs in humans,meaningful interpretation of mechanisms requires consideration of the heterogeneous nature of the diseased tissue.

  10. Previous Multiple Abdominal Surgeries: A Valid Contraindication to Abdominal Free Flap Breast Reconstruction? (United States)

    Di Candia, Michele; Asfoor, Ahmed Al; Jessop, Zita M.; Kumiponjera, Devor; Hsieh, Frank; Malata, Charles M.


    Presented in part at the following Academic Meetings: 57th Meeting of the Italian Society of Plastic, Reconstructive and Aesthetic Surgery, September 24-27, 2008, Naples, Italy.45th Congress of the European Society for Surgical Research (ESSR), June 9-12, 2010, Geneva, Switzerland.British Association of Plastic Reconstructive and Aesthetic Surgeons Summer Scientific Meeting, June 30-July 2, 2010, Sheffield Hallam University, Sheffield, UK. Background: Patients with previous multiple abdominal surgeries are often denied abdominal free flap breast reconstruction because of concerns about flap viability and abdominal wall integrity. We therefore studied their flap and donor site outcomes and compared them to patients with no previous abdominal surgery to find out whether this is a valid contraindication to the use of abdominal tissue. Patients and Methods: Twenty patients with multiple previous abdominal operations who underwent abdominal free flap breast reconstruction by a single surgeon (C.M.M., 2000-2009) were identified and retrospectively compared with a cohort of similar patients without previous abdominal surgery (sequential allocation control group, n = 20). Results: The index and control groups were comparable in age, body mass index, comorbidities, previous chemotherapy, and RT exposure. The index patients had a mean age of 54 years (r, 42-63) and an average body mass index of 27.5 kg/m2 (r, 22-38). The main previous surgeries were Caesarean sections (19), hysterectomies (8), and cholecystectomies (6). They underwent immediate (n = 9) or delayed (n = 11) reconstructions either unilaterally (n = 18) or bilaterally (n = 2) and comprising 9 muscle-sparing free transverse rectus abdominis muscle and 13 deep inferior epigastric perforator flaps.

    Full Text Available Blunt abdominal trauma constitutes 90% approximately of the abdominal injuries in children. Due to the augmented size of the child trunk in relation to their extremities, the abdominal lesions are extremely frequents. The abdominal trauma is present in 20-30% of the patients with serious trauma. It's the second cause of death for accidents after the cranial traumatism in the pediatric patient. We presented the Good Clinical Practices Guideline for Blunt Abdominal Trauma, approved by consensus in the 2nd National Good Clinical Practices Workshop in Pediatric Surgery (Manzanillo, Cuba, September 31 - October 3, 2002.

  15. Lateral abdominal muscle size at rest and during abdominal drawing-in manoeuvre in healthy adolescents. (United States)

    Linek, Pawel; Saulicz, Edward; Wolny, Tomasz; Myśliwiec, Andrzej; Kokosz, Mirosław


    Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents.

  3. Keratinocyte Growth Factor Combined with a Sodium Hyaluronate Gel Inhibits Postoperative Intra-Abdominal Adhesions

    Directory of Open Access Journals (Sweden)

    Guangbing Wei


    Full Text Available Postoperative intra-abdominal adhesion is a very common complication after abdominal surgery. One clinical problem that remains to be solved is to identify an ideal strategy to prevent abdominal adhesions. Keratinocyte growth factor (KGF has been proven to improve the proliferation of mesothelial cells, which may enhance fibrinolytic activity to suppress postoperative adhesions. This study investigated whether the combined administration of KGF and a sodium hyaluronate (HA gel can prevent intra-abdominal adhesions by improving the orderly repair of the peritoneal mesothelial cells. The possible prevention mechanism was also explored. The cecum wall and its opposite parietal peritoneum were abraded after laparotomy to induce intra-abdominal adhesion formation. Animals were randomly allocated to receive topical application of HA, KGF, KGF + HA, or normal saline (Control. On postoperative day 7, the adhesion score was assessed with a visual scoring system. Masson’s trichrome staining, picrosirius red staining and hydroxyproline assays were used to assess the magnitude of adhesion and tissue fibrosis. Cytokeratin, a marker of the mesothelial cells, was detected by immunohistochemistry. The levels of tissue plasminogen activator (tPA, interleukin-6 (IL-6, and transforming growth factor β1 (TGF-β1 in the abdominal fluid were determined using enzyme-linked immunosorbent assays (ELISAs. Western blotting was performed to examine the expression of the TGF-β1, fibrinogen and α-smooth muscle actin (α-SMA proteins in the rat peritoneal adhesion tissue. The combined administration of KGF and HA significantly reduced intra-abdominal adhesion formation and fibrin deposition and improved the orderly repair of the peritoneal mesothelial cells in the rat model. Furthermore, the combined administration of KGF and HA significantly increased the tPA levels but reduced the levels of IL-6, tumor necrosis factor α (TNF-α and TGF-β1 in the abdominal fluid. The

  5. Logistic considerations for a successful institutional approach to the endovascular repair of ruptured abdominal aortic aneurysms. (United States)

    Mayer, Dieter; Rancic, Zoran; Pfammatter, Thomas; Hechelhammer, Lukas; Veith, Frank J; Donas, Konstantin; Lachat, Mario


    The value of emergency endovascular aneurysm repair (EVAR) in the setting of ruptured abdominal aortic aneurysm remains controversial owing to differing results. However, interpretation of published results remains difficult as there is a lack of generally accepted protocols or standard operating procedures. Furthermore, such protocols and standard operating procedures often are reported incompletely or not at all, thereby making interpretation of results difficult. We herein report our integrated logistic system for the endovascular treatment of ruptured abdominal aortic aneurysms. Important components of this system are prehospital logistics, in-hospital treatment logistics, and aftercare. Further studies should include details about all of these components, and a description of these logistic components must be included in all future studies of emergency EVAR for ruptured abdominal aortic aneurysms.

  6. Ultrasonic research of abdominal organs in conditions of long-term antiorthostatic hypokinesia. (United States)

    Afonin, B V; Nichiporuk, I A; Nesterov, M A; Belousova, I V


    Change in functional activity of digestive system in space flight usually is associated with phenomenon of hypokinesia which takes place in microgravity. However, it is marked that the reorganization of a gastrointestinal tract in space flight occurs on a background of the phenomenon of venous plethora in abdominal cavity, which can also result in changes of functional activity in organs of digestive system. Insignificant amount of studies of venous plethora in abdominal cavity carried out in conditions of space flight does not allow to create a complete picture of this phenomenon. Hemodynamical changes comparable to microgravity are well-simulated in conditions of a long-term antiorthostatic hypokinesia (AH)--bed-rest in a head-down tilt. The present research was performed with the aim to study venous plethora in abdominal cavity in conditions of long-term AH.

  8. The association of mast cells and serotonin in children with chronic abdominal pain of unknown etiology

    Directory of Open Access Journals (Sweden)

    Shankar Ravi


    Full Text Available Abstract Background Abdominal pain of unknown origin affects up to 20% of school-aged children. Evaluation of children is symptom-based without clear guidelines to investigate molecular mechanisms of abdominal pain. Aberrant molecular mechanisms may increase intestinal permeability leading to interactions between the immune and nervous systems, subclinical inflammation, and visceral pain. This study evaluated the association between interleukin-6 (IL-6, mast cell infiltrates, and serotonin (5-HT levels in gastrointestinal (GI biopsies, with perceived abdominal pain in a pediatric cohort. Methods Clinical data and biopsy samples from pediatric patients (n = 48 with chronic abdominal pain, with and without inflammation were included. Formalin-fixed paraffin-embedded GI biopsies were sectioned and immunohistochemistry performed for IL-6 and 5-HT; mast cells were identified with toluidine blue stain. Histological findings were compared to self-reported abdominal pain between groups. Results There was significantly greater IL-6 immunoreactivity in biopsies with confirmed histologic inflammation (p = 0.004. There was a greater number of mast cells per HPF in non-inflammatory biopsies (3.5 ± 2.9 compared to the inflammatory biopsies (2.6 ± 1.8 p = 0.049. The non-inflammatory biopsy group was significantly less likely to respond to standard treatment as evidenced by higher pain reports (p = .018. Mast cells (p = .022 and 5-HT (p = .02 were significantly related to abdominal pain scores. Conclusions A potential association between self-reported abdominal pain, number of mast cells, and 5-HT levels, which may contribute to perceived GI pain in pediatric patients may exist.

    Background Exercise is one of the few treatments that provide significant improvements in chronic low back pain (CLBP). We developed an innovative exercise device for abdominal trunk muscles. This device can be used in a sitting or standing position and contains a built-in system to measure abdominal trunk muscle strength. We examined whether subjects can adequately use the device to perform the exercises and measure their abdominal trunk muscle strength. Methods We collected data on the body height, body weight, body mass index, and girth of 30 healthy male volunteers, and measured their grip power and trunk extensor muscle strength using a dynamometer. The volunteers performed a sit-up test as an indicator of trunk flexor muscle strength, and we measured their abdominal muscle strength using the device. We then evaluated the correlations between abdominal trunk muscle strength and anthropometric parameters as well as the strength of other muscles. In subsequent tests, 5 of the 30 subjects participated in two positron emission tomography (PET) series consisting of examinations after a resting period (control study) and during exercise (exercise study). For the exercise study, the subjects performed 2 sets of exercises for 20 minutes using the device before and after an injection of 18F-fluorodeoxyglucose (FDG). PET-computed tomography images were obtained 60 minutes after FDG injection in each study. We compared the skeletal muscle metabolism of the participants in both studies using the standardized uptake value. Results The muscle strength measured by the device and the 30-second sit-up frequency were correlated. FDG accumulation within the diaphragm and abdominal rectus muscles was significantly higher in the exercise study. Conclusion Our innovative exercise device facilitates a coordinated contraction of the abdominal trunk muscles at the anterior aspect and the roof of the core, and enables subjects to measure the strength of these muscles.

    Rivero Fernández, Miguel; Moreira Vicente, Víctor; Riesco López, José María; Rodríguez Gandía, Miguel Angel; Garrido Gómez, Elena; Milicua Salamero, José María


    Chronic abdominal pain is a common clinical problem in primary care, and is usually referred to gastroenterologists or general surgeons. Although up to 20% of cases of idiopathic abdominal pain arise in structures of the abdominal wall, this is frequently overlooked as a possible cause. It includes pain arising from structures of the abdominal wall including skin, parietal peritoneum, cellular subcutaneous tissue, aponeuroses, abdominal muscles and somatosensorial innervation from lower dorsal roots. The diagnosis is based on anamnesis and physical examination. Carnett's sign is a simple maneuver that discriminates between parietal and visceral pain. Management with topical anesthesia is effective in a majority of patients and can help to confirm the diagnosis.

    Directory of Open Access Journals (Sweden)

    Davood Farsi


    Full Text Available Background: Blunt abdominal injury is a leading cause of death in trauma patients. A reliable test predicting intra-abdominal hemorrhage would be a novel method. The study objective was to assess the diagnostic accuracy of plasma ammonia in detection of intra-abdominal bleeding in patients with blunt abdominal trauma (BAT. Materials and Methods: In this observational study, all patients suffering from BAT, referred to our university teaching hospital included. The levels of ammonia were measured at the time of emergency department admission and 1 h after initial treatment. Demographic data, vital signs, and venous blood gas reports were recorded. Findings of contrast-enhanced abdominopelvic computed tomography scan and laparotomy were assumed as a gold standard for abdominal injuries. Results: A total of 104 patients was enrolled in the study. 15 patients (14.4% had intra-abdominal hemorrhage and the mean plasma ammonia level in this group was significantly higher than the other patients on admission time (101.73 ± 5.41 μg/dL vs. 47.36 ± 26.31 μg/dL, P < 0.001. On receiver-operator characteristic curve analysis, in cutoff point of 89 μg/dL, the sensitivity, specificity, positive and negative likelihood ratios were 100% (95% confidence interval [CI], 79.6-100, 93.26% (95% CI, 86-96.8, 14.83 (95% CI, 6.84-32.12, and 0, respectively. Conclusion: The study findings suggest the measurement of ammonia level at the time of admission in the patients with BAT would be a useful test predicting intra-abdominal hemorrhage. Furthermore, decrease in the ammonia level could be a useful marker for monitoring response to treatment in these patients.

    Abakumov, M M; Smoliar, A N; Barmina, T G; Boĭko, A V; Shalimova, I G


    10 patients with adrenal damage were observed during 2.5 years. It amounted 0.93% of all patients with closed abdominal injuries. The right adrenal gland was traumatized in all cases evidently due to it's compression between right lobe of liver and vertebral column. Adrenal damage is observed quite often in combination with injuries of right liver lobe, right kidney and retroperitoneal hematoma formation. 5 patients underwent laparotomy on account of intra-abdominal bleeding, but adrenal damage was never revealed. Ultrasound and tomographic semiotics of adrenal damage was worked out, which allowed ascertaining diagnosis in 80% on application of ultrasound study and in 100% at computer tomography. Injury of one adrenal gland was not accompanied by adrenal failure and did not require hormonal replacement therapy.

  15. Abdominal pregnancy as a cause of hemoperitoneum

    Directory of Open Access Journals (Sweden)

    Shafi Sheikh


    Full Text Available The coexistence of intrauterine and extrauterine pregnancy, the heterotopic pregnancy, is a rare obstetric phenomenon. The preoperative diagnosis of this condition is very difficult; leading to a higher maternal morbidity and fetal loss. We experienced a case of intrauterine pregnancy and ruptured abdominal pregnancy implanted on the illeocaecal region in a 26-year-old primiparous woman. She was clinically misdiagnosed as a case of ruptured ectopic pregnancy, but ultrasonography showed it to be a case of heterotopic pregnancy. Subsequently, the patient was subjected to laparotomy and the ruptured abdominal pregnancy was evacuated. She continued with the intrauterine pregnancy till term and delivered a healthy female baby. Although this condition is unusual, any general surgeon in the emergency department must be aware of this complication and its management, which is often initially misdiagnosed.

  16. Atrophic coarctation of the abdominal aorta. (United States)

    Wiest, J W; Traverso, L W; Dainko, E A; Barker, W F


    Two cases illustrate the clinical manifestations and angiographic findings associated with segmental stenosis of the abdominal aorta. Such lesions represent the chronic occlusive stage of Takayasu's disease, a nonspecific inflammatory arteritis of uncertain etiology. While the disease is considered autoimmune, an infectious process may be involved. Complications typically associated with stenotic lesions of the abdominal aorta are secondary renal hypertension and ischemic symptoms secondary to vascular insufficiency. Surgical correction, the treatment of choice, has achieved excellent results for these well-localized lesions. Secondary renal hypertension was relieved by a spenorenal shunt and the disease has since been controlled with conservative management in the first patient. An aortofemoral bypass graft successfully alleviated the vascular insufficiency in the second patient, although the patient unfortunately expired from a refractory postoperative cardiac complication.

    Gravity of abdominal vessels traumatisms is secondary to multiple factors. It depends on the type of injured vessels, aetiology and associated lesions. Between September 1984 and March 1995, 22 abdominal vessel traumatisms in 16 patients (mean age: 39 years) were treated. At surgical exploration, 4 aortic and 2 renal vein lesions, 7 iliac artery and 3 renal artery contusions, 2 superior mesenteric artery dissections; 3 infra-renal vena cava ruptures and 1 superior mesenteric vein dilaceration were found. All lesions were caused by penetrant wounds secondary to firearm or blade injury or secondary to injuries due to ski or traffic accidents. In 5 cases, lesions were iatrogenic. There was no mortality in the post-operative period, 14 patients out of the 16 patients operated on have been followed during a period from 1 to 120 months.

    Institute of Scientific and Technical Information of China (English)

    Jenny N Tannoury; Bassam N Abboud


    Abdominal cocoon,the idiopathic form of sclerosing encapsulating peritonitis,is a rare condition of unknown etiology that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a fibrocollagenous membrane.Preoperative diagnosis re quires a high index of clinical suspicion.The early clinical features are nonspecific,are often not recognized and it is difficult to make a definite pre-operative diagnosis.Clinical suspicion may be generated by the recurrent episodes of small intestinal obstruction combined with relevant imaging findings and lack of other plausible etiologies.The radiological diagnosis of abdominal cocoon may now be confidently made on computed tomography scan.Surgery is important in the management of this disease.Careful dissection and excision of the thick sac with the release of the small intestine leads to complete recovery in the vast majority of cases.

    Abdul-Ghaffar, N U; Ramadan, T T; Marafie, A A


    For studying abdominal tuberculosis (TB) in Ahmadi, files off all patients admitted to our hospital with abdominal TB over 15 years (1981-1996) were reviewed. Nineteen patients are reported here. Young adults were predominant in our study. The non-Arab Asians were the most frequently affected group in relation to their population in Ahmadi, and Kuwaitis were the least frequently affected group. Abdominal pain, sweating, anorexia and fever were the most frequent presenting symptoms. Ascites and intestinal obstruction were the most frequent clinical presentations. Two patients presented with acute appendicitis and one patient had tuberculous pancreatitis. Abdominal lymph nodes, peritoneum, ileum and and caecum were the most frequently affected abdominal structures. We found laparoscopy very helpful in diagnosis of abdominal TB and we recommend it as the diagnostic method of choice. All our patients responded well to antituberculous chemotherapy. It should be kept in mind that abdominal TB still affects the indigenous and expatriate population of Kuwait.

  5. Focal epilepsy with ictal abdominal pain: a case report. (United States)

    Cerminara, Caterina; El Malhany, Nadia; Roberto, Denis; Curatolo, Paolo


    Focal epilepsy with ictal abdominal pain is an unusual partial epilepsy characterized by paroxysmal episodes of abdominal or visceral pain, disturbance of awareness and electroencephalographic abnormalities. We describe a new case of ictal abdominal pain in which gastrointestinal complaints were the only manifestation of seizures and review the previously described pediatric patients. In our patient clinical findings, ictal EEG abnormalities, and a good response to antiepileptic drugs allowed us to make a diagnosis of focal epilepsy with ictal abdominal pain. This is a rare epileptic phenomenon that should be suspected in patients with unexplained paroxysmal abdominal pain and migraine-like symptoms. We suggest that, after the exclusion of more common etiologies, focal epilepsy with ictal abdominal pain should be considered in patients with paroxysmal abdominal pain and ictal EEG abnormalities.

    AIM: To estimate the prevalence of inherited and acquired thrombophilic risk factors in patients with abdominal venous thrombosis and to compare the risk factor profiles between Budd-Chiari syndromes (BCS) and splanchnic vein thrombosis (SVT).METHODS: In this retrospective study, 36 patients with abdominal venous thrombosis were studied.The patients were divided into Budd-Chiari group (hepatic vein, IVC thrombosis) and splanchnic venous thrombosis group (portal, splenic, superior mesenteric veins) based on the veins involved. Hereditary and acquired thrombophilic risk factors were evaluated in all patients.RESULTS: Twenty patients had SVT, 14 had BCS,and 2 had mixed venous thrombosis. Ten patients (28%) had hereditary and 10 patients (28%) acquired thrombophilic risk factors. The acquired risk factors were significantly more common in the SVT group (SVT vs BCS:45% vs 7%,x2=5.7,P=0.02) while hereditary risk factors did not show significant differences between the two groups (SVT vs BCS: 25%vs 36%, x2=0.46,P=0.7). Multiple risk factors were present in one (7%) patient with BCS and in 3 patients (15%) with SVT. No risk factors were identified in 57% of patients with BCS and in 45% of patients with SVT.CONCLUSION: Hereditary and acquired risk factors play an important role in the etiopathogenesis of abdominal venous thrombosis. Acquired risk factors are significantly more common in SVT patients while hereditary factors are similar in both groups.

  7. Embarazo ectópico abdominal

    Directory of Open Access Journals (Sweden)

    Karen Luz Torres Rojas


    Full Text Available La incidencia de embarazo ectópico ha aumentado en los últimos años hasta 1:43 recién nacidos. La variedad abdominal es una de las menos frecuentes, su incidencia es de 1:10mil  nacidos vivos. El 1% de los embarazos ectópicos son abdominales y la implantación en el epiplón es una rara entidad. Pueden clasificarse como primarios o secundarios en función de que se originen o no en la cavidad peritoneal. Se presenta un caso de embarazo abdominal primario, localizado en cara posterior del útero y recto, con edad gestacional 16 semanas y feto muerto, en una paciente de 25 años, atendida en el Hospital General “Dr. Ernesto Guevara de la Serna”, con antecedentes de salud, G0 P0 A0, con método anticonceptivo DIU retirado seis meses antes. Se trata de un embarazo abdominal primario, puesto que la anatomía patológica informó ausencia de invasión trofloblástica en la trompa izquierda. El manejo placentario en este caso no permitió realizar la remoción completa de la misma. El seguimiento ecográfico y  control de gonadotropinas evidenció una evolución favorable de la paciente, sin requerir manejo de metotrexate.

    Salas-Lozano, Nereo Guillermo; Meza-Cardona, Javier; González-Fernández, Coty; Pineda-Figueroa, Laura; de Ariño-Suárez, Mauricio


    Antecedentes: el angioedema hereditario es un trastorno inflamatorio episódico, que se hereda de manera autosómica dominante y se caracteriza por episodios de edema periférico. Los pacientes pueden tener edema de la pared de cualquier víscera hueca, incluido el intestino. Caso clínico: se comunica el caso de un paciente masculino de 33 años de edad, sin antecedentes de importancia, con dolor abdominal, localizado en el epigastrio, irradiado al cuadrante inferior derecho, acompañado de 5 vómitos. La tomografía abdominal mostró engrosamiento de la pared de la segunda y tercera porción del duodeno, con infiltración de grasa y líquido libre. Los exámenes de laboratorio mostraron: concentraciones bajas del complemento C4 (5.5 mg/dL) y actividad del inhibidor de C1 del complemento de 30%. Conclusiones: el angioedema hereditario es consecuencia de la deficiencia (tipo I) o disfunción (tipo II) del inhibidor C1 del complemento. El dolor abdominal asociado con angioedema es de inicio súbito, como dolor cólico, recurrente y de intensidad moderada. En la actualidad existen dos medicamentos aprobados por la Food and Drug Administration para el tratamiento de pacientes con esta afección.

    Šarac Momir


    Full Text Available Introduction. Rupture of an abdominal aortic aneurysm (AAA is a potentially lethal state. Only half of patients with ruptured AAA reach the hospital alive. The alternative for open reconstruction of this condition is endovascular repair (EVAR. We presented a successful endovascular reapir of ruptured AAA in a patient with a number of comorbidities. Case report. A 60-year-old man was admitted to our institution due to diffuse abdominal pain with flatulence and belching. Initial abdominal ultrasonography showed an AAA that was confirmed on multislice computed tomography scan angiography which revealed a large retroperitoneal haematoma. Because of patient’s comorbidites (previous surgery of laryngeal carcinoma and one-third laryngeal stenosis, arterial hypertension and cardiomyopathy with left ventricle ejection fraction of 30%, stenosis of the right internal carotid artery of 80% it was decided that endovascular repair of ruptured AAA in local anaesthesia and analgosedation would be treatment of choice. Endovascular grafting was achieved with aorto-bi-iliac bifurcated excluder endoprosthesis with complete exclusion of the aneurysmal sac, without further enlargment of haemathoma and no contrast leakage. The postoperative course of the patient was eventless, without complications. On recall examination 3 months after, the state of the patient was well. Conclusion. The alternative for open reconstruction of ruptured AAA in haemodynamically stable patients with suitable anatomy and comorbidities could be emergency EVAR in local anesthesia. This technique could provide greater chances for survival with lower intraoperative and postoperative morbidity and mortality, as shown in the presented patient.

  10. Midgut malrotation with chronic abdominal pain

    Directory of Open Access Journals (Sweden)

    Anil K Wanjari


    Full Text Available Abnormalities in midgut rotation occur during the physiological herniation of midgut between the 5 th and 10 th week of gestation. The most significant abnormality is narrow small bowel mesentery which is prone to volvulus. This occurs most frequently in the neonatal period, less commonly midgut malrotation presents in adulthood with either acute volvulus or chronic abdominal symptoms. It is the latter group that represents a diagnostic challenge. We report a case of a 17-year-old male patient who presented with 10-year history of nonspecific gastro-intestinal symptoms. After extensive investigation the patient was diagnosed with midgut malrotation following computed tomography of abdomen. The patient was treated with a laparoscopic Ladd′s procedure and at 3 months he was gaining weight and had stopped vomiting. A laparoscopic Ladd′s procedure is an acceptable alternative to the open technique in treating symptomatic malrotation in adults. Midgut malrotation is a rare congenital anomaly which may present as chronic abdominal pain. Abdominal CT is helpful for diagnosis.

  11. [Abdominal multi-organ transplantation in dogs]. (United States)

    Kumagae, T


    Abdominal multi-organ transplantation including the liver, gallbladder, spleen, pancreas, kidneys, adrenal glands and gastrointestinal tract was attempted in 8 dogs. Each experiment was discontinued when the recipient deteriorated. Immersion hypothermia was introduced in both the donor and recipient until the esophageal temperature reached 27-30 degrees C. Whole abdominal organs of the donor were removed in an en-bloc fashion at 20 degrees C of the graft temperature after additional cooling by ice slush scattering into the abdominal cavity. Transplantation was carried out orthotopically in the following sequence: (1) the proximal aorta, (2) suprahepatic vena cava, (3) distal aorta, (4) infrahepatic vena cava. The alimentary tract was reconstructed by gastro-gastrostomy and colo-colostomy. The ureters were implanted in the bladder. Cold ischemic time of the graft was about 40 minutes. Heparin was not used throughout the procedure. Five out of eight dogs were alive for more than 24 hours and two of them survived for 60 hours with good recovery. No immunosuppressant was given. Though the result in the present study was far from satisfaction, the experiment may provide a possibility of a new experimental model for transplantation, especially regarding pathophysiology and interrelationship of the transplanted complex organs.

  12. Sagittal Abdominal Diameter: Application in Clinical Practice

    Directory of Open Access Journals (Sweden)

    Thaís Da Silva-Ferreira


    Full Text Available Excess visceral fat is associated with cardiovascular risk factors. Sagittal abdominal diameter (SAD has recently been highlighted as an indicator of abdominal obesity, and also may be useful in predicting cardiovascular risk. The purpose of the present study was to review the scientific literature on the use of SAD in adult nutritional assessment. A search was conducted for scientific articles in the following electronic databases: SciELO , MEDLINE (PubMed and Virtual Health Library. SAD is more associated with abdominal fat (especially visceral, and with different cardiovascular risk factors, such as, insulin resistance, blood pressure, and serum lipoproteins than the traditional methods of estimating adiposity, such as body mass index and waist-to-hip ratio. SAD can also be used in association with other anthropometric measures. There are still no cut-off limits established to classify SAD as yet. SAD can be an alternative measure to estimate visceral adiposity. However, the few studies on this diameter, and the lack of consensus on the anatomical site to measure SAD, are obstacles to establish cut-off limits to classify it.

    Purpose: The aim of this study is to develop the abdominal compression device which could control pressure level according to the abdominal respiratory motion and evaluate its feasibility. Methods: In this study, we focused on developing the abdominal compression device which could control pressure level at any point of time so the developed device is possible to use a variety of purpose (gating technique or respiratory training system) while maintaining the merit of the existing commercial device. The compression device (air pad form) was designed to be able to compress the front and side of abdomen and the pressure level of the abdomen is controlled by air flow. Pressure level of abdomen (air flow) was determined using correlation data between external abdominal motion and respiratory volume signal measured by spirometer. In order to verify the feasibility of the device, it was necessary to confirm the correlation between the abdominal respiratory motion and respiratory volume signal and cooperation with respiratory training system also checked. Results: In the previous study, we could find that the correlation coefficient ratio between diaphragm and respiratory volume signal measured by spirometer was 0.95. In this study, we confirmed the correlation between the respiratory volume signal and the external abdominal motion measured by belt-transducer (correlation coefficient ratio was 0.92) and used the correlated respiratory volume data as an abdominal pressure level. It was possible to control the pressure level with negligible time delay and respiratory volume data based guiding waveforms could be properly inserted into the respiratory training system. Conclusion: Through this feasibility study, we confirmed the correlation between the respiratory volume signal and the external abdominal motion. Also initial assessment of the device and its compatibility with the respiratory training system were verified. Further study on application in respiratory gated

  14. Management of abdominal sepsis--a paradigm shift? (United States)

    Leppäniemi, Ari; Kimball, Edward J; De Laet, Inneke; Malbrain, Manu L N G; Balogh, Zsolt J; De Waele, Jan J


    The abdomen is the second most common source of sepsis and secondary peritonitis. The most common causes of abdominal sepsis are perforation, ischemic necrosis or penetrating injury to the abdominal viscera. Management consists of control of the infection source, restoration of gastrointestinal tract (GI) function, systemic antimicrobial therapy and support of organ function. Mortality after secondary peritonitis is still high. Excluding patient-related factors such as age or co-morbidities that can not be influenced at the time of intervention, delay to surgical intervention and inability to obtain source control are the main determinants of outcome. In patients with severe physiological derangement or difficult intraperitoneal conditions, where a prolonged operation and complete anatomical repair may not be possible or appropriate, it is becoming increasingly popular to utilize a damage control strategy with abbreviated laparotomy and planned reoperations. The main components of damage control laparotomy for secondary peritonitis are postponing the reconstruction of intestinal anastomoses to a second operation (deferred anastomosis) and leaving the abdomen open with some form of temporary abdominal closure (TAC). Advances in the management techniques of the open abdomen and new negative pressure-based TAC-devices have significantly reduced the previously observed prohibitive morbidity associated with open abdomens. These advancements have led to current fascial closure rates after TAC approaching 90%. The cornerstones of appropriate antimicrobial therapy are the timing, spectrum and dosing of antibiotics. Enteral nutrition should be started as soon as possible in hemodynamically stable patients but withheld when the patient is on a significant dose of vasopressors or whenever GI hypoperfusion is suspected. Timely source control with appropriate use of antimicrobial agents and early intensive care offers the best chance of survival for patients with abdominal

[University of Amsterdam, Department of Clinical Epidemiology, Biostatistics, and Bioinformatics, Academic Medical Center, Amsterdam (Netherlands); Boermeester, Marja A. [University of Amsterdam, Department of Surgery, Academic Medical Center, Amsterdam (Netherlands)


    The level of inter-observer agreement of abdominal computed tomography (CT) in unselected patients presenting with acute abdominal pain at the Emergency Department (ED) was evaluated. Two hundred consecutive patients with acute abdominal pain were prospectively included. Multi-slice CT was performed in all patients with intravenous contrast medium only. Three radiologists independently read all CT examinations. They recorded specific radiological features and a final diagnosis on a case record form. We calculated the proportion of agreement and kappa values, for overall, urgent and frequently occurring diagnoses. The mean age of the evaluated patients was 46 years (range 19-94), of which 54% were women. Overall agreement on diagnoses was good, with a median kappa of 0.66. Kappa values for specific urgent diagnoses were excellent, with median kappa values of 0.84, 0.90 and 0.81, for appendicitis, diverticulitis and bowel obstruction, respectively. Abdominal CT has good inter-observer agreement in unselected patients with acute abdominal pain at the ED, with excellent agreement for specific urgent diagnoses as diverticulitis and appendicitis.

  16. Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

    LENUS (Irish Health Repository)

    Sugrue, Michael


    BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

  17. Significance of residual abdominal masses in children with abdominal Burkitt's lymphoma

    Karmazyn, B.; Horev, G.; Kornreich, L. [Dept. of Diagnostic Radiology, Schneider Children' s Medical Center of Israel, Petah-Tikva (Israel); Ash, S.; Goshen, Y.; Yaniv, I. [Dept. of Hematology and Oncology, Schneider Children' s Medical Center of Israel, Petah-Tikva (Israel)


    Purpose: To evaluate the natural history of children with abdominal Burkitt's lymphoma who had complete clinical remission and residual abdominal mass after treatment. Material and methods: The charts and imaging findings of all children with abdominal Burkitt's lymphoma treated and followed at our medical center between 1988 and 1999 were reviewed for the presence, management, clinical course, and prognosis of residual mass. Results: Only children who achieved complete clinical remission were included. The study group consisted of 33 children (20 boys and 13 girls) aged 2.6-17.6 years (mean 7.2 years). Of these, seven (20.6 %) were found to have a residual abdominal mass. Two underwent second-look operation with no evidence of viable tumor on histology. The remaining five were followed by imaging studies for 2.2-9.1 years (mean 6.1 years); none relapsed. Conclusion: Residual mass is not uncommon in children with abdominal Burkitt's lymphoma. The presence of residual mass in a child with complete clinical remission does not alter the long-term prognosis. Therefore, in children with Burkitt's lymphoma and residual mass with no other signs of disease activity, expectant watching may be appropriate. (orig.)

    Abnormal pain processing in the central nervous system may be related to abdominal pain in patients with Crohn's disease (CD). The purpose of this study was to investigate changes in resting-state brain activity in patients with CD in remission and its relationship with the presence of abdominal pain. Twenty-five patients with CD and with abdominal pain, 25 patients with CD and without abdominal pain, and 32 healthy subjects were scanned using a 3.0-T functional magnetic resonance imaging scanner. Regional homogeneity (ReHo) was used to assess resting-state brain activity. Daily pain scores were collected 1 week before functional magnetic resonance imaging. We found that patients with abdominal pain exhibited lower ReHo values in the insula, middle cingulate cortex (MCC), and supplementary motor area and higher ReHo values in the temporal pole. In contrast, patients without abdominal pain exhibited lower ReHo values in the hippocampal/parahippocampal cortex and higher ReHo values in the dorsomedial prefrontal cortex (all P pain scores for patients with abdominal pain (r = -0.53, P = 0.008 and r = -0.61, P = 0.002, respectively). These findings suggest that resting-state brain activities are different between remissive patients with CD with and without abdominal pain and that abnormal activities in insula and MCC are closely related to the severity of abdominal pain.

  19. Extraction of fetal ECG signal by an improved method using extended Kalman smoother framework from single channel abdominal ECG signal. (United States)

    Panigrahy, D; Sahu, P K


    This paper proposes a five-stage based methodology to extract the fetal electrocardiogram (FECG) from the single channel abdominal ECG using differential evolution (DE) algorithm, extended Kalman smoother (EKS) and adaptive neuro fuzzy inference system (ANFIS) framework. The heart rate of the fetus can easily be detected after estimation of the fetal ECG signal. The abdominal ECG signal contains fetal ECG signal, maternal ECG component, and noise. To estimate the fetal ECG signal from the abdominal ECG signal, removal of the noise and the maternal ECG component presented in it is necessary. The pre-processing stage is used to remove the noise from the abdominal ECG signal. The EKS framework is used to estimate the maternal ECG signal from the abdominal ECG signal. The optimized parameters of the maternal ECG components are required to develop the state and measurement equation of the EKS framework. These optimized maternal ECG parameters are selected by the differential evolution algorithm. The relationship between the maternal ECG signal and the available maternal ECG component in the abdominal ECG signal is nonlinear. To estimate the actual maternal ECG component present in the abdominal ECG signal and also to recognize this nonlinear relationship the ANFIS is used. Inputs to the ANFIS framework are the output of EKS and the pre-processed abdominal ECG signal. The fetal ECG signal is computed by subtracting the output of ANFIS from the pre-processed abdominal ECG signal. Non-invasive fetal ECG database and set A of 2013 physionet/computing in cardiology challenge database (PCDB) are used for validation of the proposed methodology. The proposed methodology shows a sensitivity of 94.21%, accuracy of 90.66%, and positive predictive value of 96.05% from the non-invasive fetal ECG database. The proposed methodology also shows a sensitivity of 91.47%, accuracy of 84.89%, and positive predictive value of 92.18% from the set A of PCDB.

  20. Invasive group A Streptococcus resulting in sepsis and abdominal wall abscess after adenotonsillectomy. (United States)

    Wilson, Paul F; Wannemuehler, Todd J; Matt, Bruce H


    Systemic infectious complications following adenotonsillectomy are exceedingly rare. We describe an otherwise healthy 2-year-old patient who developed group A beta-hemolytic Streptococcus sepsis and presumptive scarlet fever 3 days after an uncomplicated adenotonsillectomy. After resolution of fever, rash, and discharge home on antibiotics, the patient returned on postoperative day 10 with an abdominal wall abscess. This is the first reported case of an abdominal wall abscess as a complication of adenotonsillectomy. This case demonstrates that an awareness of unexpected infectious complications of adenotonsillectomy should be a part of postsurgical management. Laryngoscope, 125:1230-1232, 2015.

  1. [Effect of anaesthesia on incidence of postoperative delirium after major abdominal surgery in elderly patients]. (United States)

    Zabolotskikh, I B; Trembach, N V


    Delirium can be caused by haemodynamics abnormalities during anaesthesia. The main role in delirium appearance is given to decreasing of cerebral perfusion pressure. Especially it can happen in patients with underlying intracranial hypertension. Anaesthetics effects on intracranial pressure are different therefore cerebral hypoperfusion can happens in these patients even without systemic hypotension. Purpose of the study was to define an effect of cerebral perfusion pressure decreasing during different technics of anaesthesia on frequency of delirium in elderly patients after major abdominal surgery. The article deals with results of study of 182 patients (medium age 69 y.o.) underwent elective major abdominal surgery. Delirium frequency was 11%, continuing of delirium was 3 days. The frequency of delirium was higher in patients who had got anaesthesia based on sevoflurane. Additionally these patients had higher frequency of cerebral perfusion pressure decreasing. Conclusions; Anaesthesia based on sevoflurane is characterized by higher frequency of postoperative delirium in elderly patients after major abdominal surgery.

  2. Interaction between intra-abdominal pressure and positive-end expiratory pressure

    Directory of Open Access Journals (Sweden)

    Jamili Anbar Torquato


    Full Text Available OBJECTIVE: The aim of this study was to quantify the interaction between increased intra-abdominal pressure and Positive-End Expiratory Pressure. METHODS: In 30 mechanically ventilated ICU patients with a fixed tidal volume, respiratory system plateau and abdominal pressure were measured at a Positive-End Expiratory Pressure level of zero and 10 cm H2O. The measurements were repeated after placing a 5 kg weight on the patients' belly. RESULTS: After the addition of 5 kg to the patients' belly at zero Positive-End Expiratory Pressure, both intra-abdominal pressure (p<0.001 and plateau pressures (p=0.005 increased significantly. Increasing the Positive-End Expiratory Pressure levels from zero to 10 cm H2O without weight on the belly did not result in any increase in intra-abdominal pressure (p=0.165. However, plateau pressures increased significantly (p< 0.001. Increasing Positive-End Expiratory Pressure from zero to 10 cm H2O and adding 5 kg to the belly increased intra-abdominal pressure from 8.7 to 16.8 (p<0.001 and plateau pressure from 18.26 to 27.2 (p<0.001. Maintaining Positive-End Expiratory Pressure at 10 cm H2O and placing 5 kg on the belly increased intra-abdominal pressure from 12.3 +/- 1.7 to 16.8 +/- 1.7 (p<0.001 but did not increase plateau pressure (26.6+/-1.2 to 27.2 +/-1.1 -p=0.83. CONCLUSIONS: The addition of a 5kg weight onto the abdomen significantly increased both IAP and the airway plateau pressure, confirming that intra-abdominal hypertension elevates the plateau pressure. However, plateau pressure alone cannot be considered a good indicator for the detection of elevated intra-abdominal pressure in patients under mechanical ventilation using PEEP. In these patients, the intra-abdominal pressure must also be measured.

    Introducción: la presión intraabdominal es el estado de equilibrio de la presión de la cavidad abdominal en reposo y puede presentar cambios durante la ventilación mecánica o espontánea. El objetivo fue determinar la presión intraabdominal como predictor de cirugía en el paciente con dolor abdominal agudo. Métodos: se llevó a cabo un estudio de casos y controles anidado en una cohorte de pacientes con dolor abdominal agudo en el servicio de urgencias de un hospital de segundo nivel, en el periodo comprendido entre abril y diciembre de 2013. Se incluyeron 37 pacientes, todos fueron intervenidos quirúrgicamente con previa toma de la presión intraabdominal. Se formaron los grupos con el resultado del estudio anatomopatológico: con evidencia de proceso inflamatorio abdominal agudo (n = 28) y sin evidencia de proceso inflamatorio abdominal agudo (n = 9). Resultados: en los casos el 100 % presentó presión intraabdominal alta con una p = 0.01, RM: 5 (IC 95 %: 2.578-9.699). En los casos la media de la presión intraabdominal fue de 11.46 y en los controles de 9.2 (p = 0.183). Conclusiones: el dolor abdominal que requiere cirugía para su resolución tiene relación directa con una presión intraabdominal > 5 mmHg.

    Kryvoruchko, I A; Ivanova, Iu V; Povelichenko, M S; Andreieshchev, S A


    Investigations were conducted in 53 patients, operated on in 2013 yr for abdominal sepsis (AS). The patients state severity was determined in accordance to the systemic inflammatory reaction and the polyorgan insufficiency severity. In 28 patients (group I) AS was diagnosed, in 14 (group II)--severe AS, in 11 (group III)--a septic shock. Tactics of surgical management of the patients have included two main measures: the infection origin control (source control), and control of the affected organ function and systemic defense mechanisms (damage control). In all the patients in AS the intraabdominal pressure rising was revealed. Syndrome of intraabdominal hypertension was noted in 10 (18.9%) patients (in 4--while presence of severe AS, and in 6--in septic shock). Lethality was the highest in intraabdominal hypertension degrees III and IV (11 of 25 patients have died).

    Cheung Kent Shek


    Full Text Available 【Abstract】Objective: Focused Abdominal Sono-graphy for Trauma (FAST is widely used for the detection of intraperitoneal free fluids in patients suffering from blunt abdominal trauma (BAT. This study aimed at assessing the diagnostic accuracy of this investigation in a designated trauma centre. Methods: This was a retrospective study of BAT pa-tients over a 6 year period seen in a trauma centre in Hong Kong. FAST findings were compared with laparotomy, ab-dominal computed tomography or autopsy findings, which served as the gold standard for presence of intraperi-toneal free fluids. The patients who did not have FAST or gold standard confirmatory test performed, had preexisting peritoneal fluid, died at resuscitation or had imcomplete docu-mentation of FAST findings were excluded. The performance of FAST was expressed as sensitivity, specificity, predic-tive values (PV, likelihood ratios (LR and accuracy. Results: FAST was performed in 302 patients and 153 of them were included in this analysis. The sensitivity, specificity, positive PV, negative PV, positive LR, negative LR and accuracy for FAST were respectively 50.0%, 97.3%, 87.0%, 84.6%, 18.8, 0.5 and 85.0%. FAST was found to be more sensitive in less severely injured patients and more specific in more severely injured patients. Conclusion: FAST is a reliable investigation in the initial assessment of BAT patients. The diagnostic values of FAST could be affected by the severity of injury and staff training is needed to further enhance its effective use.

  9. Diagnostic value of ultrasound in children with recurrent abdominal pain. (United States)

    van der Meer, S B; Forget, P P; Arends, J W; Kuijten, R H; van Engelshoven, J M


    In order to investigate the diagnostic value of ultrasound in children with recurrent abdominal pain and to estimate the clinical relevance of rare organic causes of abdominal pain in these patients, we prospectively examined 93 children aged between 5.5 and 12 years by means of abdominal ultrasound. In 3 patients (3.2%) an anatomic abnormality was detected, which could not account for the abdominal pain. We conclude that many organic abnormalities, that could be diagnosed by ultrasound, are clinically irrelevant as a cause of recurrent abdominal pain in children and therefore ultrasound does not significantly contribute to the diagnosis. However, ultrasound can still play a role in the work-up of children with recurrent abdominal pain in avoiding unnecessary radiologic X-ray procedures.

  10. Recurrent abdominal pain: when an epileptic seizure should be suspected?

    Directory of Open Access Journals (Sweden)

    Franzon Renata C.


    Full Text Available Recurrent episodes of abdominal pain are common in childhood. Among the diagnostic possibilities are migraine and abdominal epilepsy (AE. AE is an infrequent syndrome with paroxystic episodes of abdominal pain, awareness disturbance, EEG abnormalities and positive results with the introduction of antiepileptic drugs. We present one 6 year-old girl who had short episodes of abdominal pain since the age of 4. The pain was followed by cry, fear and occasionally secondary generalization. MRI showed tumor in the left temporal region. As a differential diagnosis, we report a 10 year-old boy who had long episodes of abdominal pain accompanied by blurring of vision, vertigo, gait ataxia, dysarthria, acroparesthesias and vomiting. He received the diagnosis of basilar migraine. In our opinion, AE is part of a large group (partial epilepsies and does not require a special classification. Pediatric neurologists must be aware of these two entities that may cause abdominal pain.

  11. Duodenal perforation as result of blunt abdominal trauma in childhood. (United States)

    Hartholt, Klaas Albert; Dekker, Jan Willem T


    Blunt abdominal trauma may cause severe intra-abdominal injuries, while clinical findings could be mild or absent directly after the trauma. The absence of clinical findings could mislead physicians into underestimating the severity of the injury at the primary survey, and inevitably leads to a delay in the diagnosis. The Blunt Abdominal Trauma in Children (BATiC) score may help to identify children who are at a high risk for intra-abdominal injuries in an early stage and requires additional tests directly. A case of a 10-year-old girl with a duodenal perforation after a blunt abdominal trauma is presented. A delay in diagnosis may lead to an increased morbidity and mortality rate. A low admission threshold for children with abdominal pain after a blunt trauma is recommended.

    In this case we presented a patient who were admitted to surgery department with complaints of abdominal pain and nausea. There were no pathological findings on physical examination, direct abdominal x-ray, chest radiograph and biochemical parameters. At proximal of the celiac trunk, it was shown approximately 3x2 cm in size fusiform aneurysmal dilatation on the patient%u2019s abdominal ultrasonography and turbulence, arterial flow on the patient%u2019s abdominal doppler ultrasonography subsequently. In abdominal computed tomography we detected dense calcifications, dilatation and hypodensities that may belong to a thrombus in the lumen superior mesenteric vein (SMV. At the same time, approximately 3.5 cm segment of trunk celiak we observed aneurysm dilatation which reaching 2 cm at the widest point. Celiac trunk aneurysm is a rare cause of abdominal pain and often noticed after the complicated, thus it must always be kept in mind in the differential diagnosis.

    Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital - including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome) - compressive - including 'nutcracker' syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome. In this article, we aimed to illustrate imaging findings that are characteristic of these syndromes, through studies conducted at our institution, as well as to perform a brief review of the literature on this topic.

    Mallia, Alvin James; Ashwood, Neil; Arealis, George; Galanopoulos, Ilias


    Retroperitoneal abscesses are unusual occurrences with occult and insidious presentations. There is often a lack of abdominal signs, leading to delays in drainage and high mortality rates. We report a case of thigh emphysema in an 88-year-old patient with diabetes. Prior to admission the patient reported a vague 4-week history of left thigh pain and an inability to fully weight bear. She presented to our emergency department with sepsis and acute kidney impairment. An X-ray of her left femur ...

    Directory of Open Access Journals (Sweden)

    Al Soub Hussam


    Full Text Available We describe here a case of abdominal abscesses due to Mycobacterium fortuitum following liposuction. The abscesses developed three months after the procedure and diagnosis was delayed for five months. The clues for diagnosis were persistent pus discharge in spite of broad spectrum antibiotics and failure to grow any organisms on routine culture. This condition has been rarely reported; however, the increasing number of liposuction procedures done and awareness among physicians will probably result in the identification of more cases. Combination antibiotic therapy with surgical drainage in more extensive diseases is essential for cure.

    Full Text Available Roundworm infestation is common in tropical climate population with a low socioeconomic status. We describe a case of a young male with polytrauma accident who presented with small bowel dysfunction with a high gastric residual volume during enteral feeding. While searching the etiology, the intensivist performed bedside abdominal ultrasound (USG as a part of whole body USG screening along with clinical examination using different frequency probes to examine bowel movement and ultimately found ascariasis to be the cause. This case report will boost up the wide use of bedside USG by critical care physicians in their patient workup.

  17. Exercise-related transient abdominal pain (ETAP). (United States)

    Morton, Darren; Callister, Robin


    Exercise-related transient abdominal pain (ETAP), commonly referred to as 'stitch', is an ailment well known in many sporting activities. It is especially prevalent in activities that involve repetitive torso movement with the torso in an extended position, such as running and horse riding. Approximately 70% of runners report experiencing the pain in the past year and in a single running event approximately one in five participants can be expected to suffer the condition. ETAP is a localized pain that is most common in the lateral aspects of the mid abdomen along the costal border, although it may occur in any region of the abdomen. It may also be related to shoulder tip pain, which is the referred site from tissue innervated by the phrenic nerve. ETAP tends to be sharp or stabbing when severe, and cramping, aching, or pulling when less intense. The condition is exacerbated by the postprandial state, with hypertonic beverages being particularly provocative. ETAP is most common in the young but is unrelated to sex or body type. Well trained athletes are not immune from the condition, although they may experience it less frequently. Several theories have been presented to explain the mechanism responsible for the pain, including ischemia of the diaphragm; stress on the supportive visceral ligaments that attach the abdominal organs to the diaphragm; gastrointestinal ischemia or distension; cramping of the abdominal musculature; ischemic pain resulting from compression of the celiac artery by the median arcuate ligament; aggravation of the spinal nerves; and irritation of the parietal peritoneum. Of these theories, irritation of the parietal peritoneum best explains the features of ETAP; however, further investigations are required. Strategies for managing the pain are largely anecdotal, especially given that its etiology remains to be fully elucidated. Commonly purported prevention strategies include avoiding large volumes of food and beverages for at least 2 hours

  18. Surrogate Markers of Abdominal Aortic Aneurysm Progression. (United States)

    Wanhainen, Anders; Mani, Kevin; Golledge, Jonathan


    The natural course of many abdominal aortic aneurysms (AAA) is to gradually expand and eventually rupture and monitoring the disease progression is essential to their management. In this publication, we review surrogate markers of AAA progression. AAA diameter remains the most widely used and important marker of AAA growth. Standardized reporting of reproducible methods of measuring AAA diameter is essential. Newer imaging assessments, such as volume measurements, biomechanical analyses, and functional and molecular imaging, as well as circulating biomarkers, have potential to add important information about AAA progression. Currently, however, there is insufficient evidence to recommend their routine use in clinical practice.

  19. Overview of point-of-care abdominal ultrasound in emergency and critical care. (United States)

    Kameda, Toru; Taniguchi, Nobuyuki


    Point-of-care abdominal ultrasound (US), which is performed by clinicians at bedside, is increasingly being used to evaluate clinical manifestations, to facilitate accurate diagnoses, and to assist procedures in emergency and critical care. Methods for the assessment of acute abdominal pain with point-of-care US must be developed according to accumulated evidence in each abdominal region. To detect hemoperitoneum, the methodology of a focused assessment with sonography for a trauma examination may also be an option in non-trauma patients. For the assessment of systemic hypoperfusion and renal dysfunction, point-of-care renal Doppler US may be an option. Utilization of point-of-care US is also considered in order to detect abdominal and pelvic lesions. It is particularly useful for the detection of gallstones and the diagnosis of acute cholecystitis. Point-of-case US is justified as the initial imaging modality for the diagnosis of ureterolithiasis and the assessment of pyelonephritis. It can be used with great accuracy to detect the presence of abdominal aortic aneurysm in symptomatic patients. It may also be useful for the diagnoses of digestive tract diseases such as appendicitis, small bowel obstruction, and gastrointestinal perforation. Additionally, point-of-care US can be a modality for assisting procedures. Paracentesis under US guidance has been shown to improve patient care. US appears to be a potential modality to verify the placement of the gastric tube. The estimation of the amount of urine with bladder US can lead to an increased success rate in small children. US-guided catheterization with transrectal pressure appears to be useful in some male patients in whom standard urethral catheterization is difficult. Although a greater accumulation of evidences is needed in some fields, point-of-care abdominal US is a promising modality to improve patient care in emergency and critical care settings.

    To assess the outcomes of endovascular aortic aneurysm repair (EVAR) for the treatment of an abdominal aortic aneurysm in patients undergoing curative surgical treatment for concomitant abdominal malignancy. The study included 12 patients with abdominal neoplasia and an abdominal aortic aneurysm (AAA), which was treated by surgery and stent EVAR. The neoplasm consisted of the gastric, colorectal, pancreas, prostate, and gall bladder. The follow up period was 3-21 months (mean 11.8 months). All medical records and imaging analyses were reviewed by CTA and/or color Doppler US, retrospectively. Successful endoluminal repair was accomplished in all twelve patients. The mean interval time between EVAR and surgery was 58.6 days. Small amounts of type 2 endoleaks were detected in two patients (17%). One patient developed adult respiratory distress syndrome after Whipple's operation 20 days after surgery, which led to hopeless discharge. No procedure-related mortality, morbidity, or graft-related infection was noted. Exclusion of AAA in patients with accompanying malignancy show with a relatively low procedure morbidity and mortality. Hence, endoluminal AAA repair in patients with synchronous neoplasia may allow greater flexibility in the management of an offending malignancy

  3. [Abdominal artery aneurysm and associated surgical abdominal diseases: towards optimal timing]. (United States)

    Stilo, Francesco; Mirenda, Francesco; Mandolfino, Tommaso; La Spada, Michele; D'Alfonso, Mario; Carmignani, Amedeo; De Caridi, Giovanni; Benedetto, Filippo; Spinelli, Francesco


    The purpose of this study was to assess which modalities offered the best timing in the treatment of abdominal aortic aneurysms associated with other abdominal surgical diseases. From January 1984 to December 2002, 372 patients underwent surgery for abdominal aortic aneurysms, 350 men (94%) and 22 women (6%), mean age 72 years. Of these 10% were operated on urgently. The traditional open technique was used in 307 patients, and the endovascular method in the remaining 65 cases. In 40 patients (11%) we observed other associated abdominal diseases which were treated during the same operation in 34 cases (85%). We had three deaths in the 34 cases treated in the same operation (9%). In the remaining cases no perioperative mortality was registered. There were no cases of prosthesis infection. The mean hospital stay was 9 days. Simultaneous treatment appears, on the one hand, to carry an increased operative risk and increased mortality and, on the other, to present the advantage of having to perform only one surgical procedure. The advent of the endovascular method allows us to postpone the treatment of the associated disease without increasing the technical difficulty of the second operation.

  4. Facial and abdominal hair growth in hirsutism: a computerized evaluation. (United States)

    Hines, G; Moran, C; Huerta, R; Folgman, K; Azziz, R


    Methods of objectively assessing the growth rate of hairs in hirsute women have generally required some form of shaving and have focused on studying hairs affecting the face, which has reduced the number of patients willing or able to participate in such studies. A possible solution is to assess the terminal hairs on the lower abdomen (ie, the male escutcheon) because these two body areas are the most frequently affected with excess hair growth in hirsute patients. Nonetheless, it is unclear how the growth characteristics (density, diameter, and growth rate) of the hairs on the abdomen and face differ in these patients. We hypothesize that the growth characteristics of terminal hairs on the abdomen and face are similar and that evaluation of either area may be sufficient in assessing the hair growth rate of these patients. To objectively evaluate hair growth in the face and abdomen in hirsute patients, we developed a computer-aided image analysis system capable of measuring several growth parameters. Twenty hirsute women (12 white and 8 black), aged 31.2 +/- 6.1 years, were studied. Facial and abdominal skin areas were shaved, and 3 to 5 days later the areas were photographed through a calibrated glass plate and 5 terminal hairs were plucked from each area. The daily hair growth rate (assessed by photography and by direct measurement of the plucked hair), the density of hairs (number of hairs per surface area assessed by photography), and hair diameter (of the plucked hairs) were determined. The extent of hirsutism was also measured, albeit subjectively, by a modification of the Ferriman-Gallwey method, with each area given a score of 0 (no terminal hairs seen) to 4 (terminal hairs in a pattern similar to that of a very hirsute man). Facial, abdominal, and total Ferriman-Gallwey scores were 1.3 +/- 0.6, 1.8 +/- 0.9, and 12.5 +/- 5.4, respectively. Our results indicated that facial hairs were distributed in greater density and had a greater diameter than abdominal

    @@ Aortic dissection occurs when layers of the aortic walls are separated by the blood flow through an intimal tear. Dissection of the aorta most frequently originates in the ascending aorta (70%), followed by the descending aorta (22%), the aortic arch (7%) and the abdominal aorta (1/%).1 The dissection limited to the abdominal aorta is rare.2 An isolated abdominal aortic dissection (IAAD) concomitant with an abdominal aortic aneurysm (AAA) is uncommon. We present here one patient with IAAD and AAA treated by endovascular therapy.

    Legakis Nikolaos


    Full Text Available Abstract Background Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. We discuss one such rare case, outlining the fact that an intra-operative surprise diagnosis could have been facilitated by previous investigations. Case presentation A 56 year-old man presented in A&E department with small bowel ileus. He had a history of 6 similar episodes of small bowel obstruction in the past 4 years, which resolved with conservative treatment. Pre-operative work-up did not reveal any specific etiology. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. Conclusion Idiopathic sclerosing encapsulating peritonitis, although rare, may be the cause of a common surgical emergency such as small bowel ileus, especially in cases with attacks of non-strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel ileus combined with relevant imaging findings and lack of other plausible etiologies. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a "surprise" upon laparotomy and result in proper management.

  11. Methods for abdominal respiratory motion tracking. (United States)

    Spinczyk, Dominik; Karwan, Adam; Copik, Marcin


    Non-invasive surface registration methods have been developed to register and track breathing motions in a patient's abdomen and thorax. We evaluated several different registration methods, including marker tracking using a stereo camera, chessboard image projection, and abdominal point clouds. Our point cloud approach was based on a time-of-flight (ToF) sensor that tracked the abdominal surface. We tested different respiratory phases using additional markers as landmarks for the extension of the non-rigid Iterative Closest Point (ICP) algorithm to improve the matching of irregular meshes. Four variants for retrieving the correspondence data were implemented and compared. Our evaluation involved 9 healthy individuals (3 females and 6 males) with point clouds captured in opposite breathing phases (i.e., inhalation and exhalation). We measured three factors: surface distance, correspondence distance, and marker error. To evaluate different methods for computing the correspondence measurements, we defined the number of correspondences for every target point and the average correspondence assignment error of the points nearest the markers.

  12. Abdominal manifestations of cystic fibrosis in children

    Energy Technology Data Exchange (ETDEWEB)

    Chaudry, Gulraiz; Navarro, Oscar M.; Levine, Daniel S.; Oudjhane, Kamaldine [University of Toronto, Department of Diagnostic Imaging, Hospital for Sick Children, Toronto, ON (Canada)


    Pulmonary complications remain the main cause of mortality in cystic fibrosis, but the presenting symptoms in children are often related to gastrointestinal or pancreaticobiliary disease. Furthermore, abdominal manifestations are now seen throughout childhood, from infancy to adolescence. The child might present in the neonatal period with meconium ileus or its attendant complications. The older child might present with distal intestinal obstruction syndrome or colonic stricture secondary to high doses of pancreatic enzyme replacement. Less-common gastrointestinal manifestations include intussusception, duodenitis and fecal impaction of the appendix. Most children also show evidence of exocrine pancreatic deficiency. Radiologically, the combination of fat deposition and pancreatic fibrosis leads to varying CT and MR appearances. A higher than normal incidence of pancreatic cysts and calcification is also seen. Decreased transport of water and chloride also increases the viscosity of bile, with subsequent obstruction of the biliary ductules. If extensive, this can progress to obstructive cirrhosis, portal hypertension and esophageal varices. Diffuse fatty infiltration, hypersplenism and gallstones are also commonly seen in these patients. We present a pictorial review of the radiological appearance of these abdominal manifestations. The conditions are dealt with individually, together with typical appearances in various imaging modalities. (orig.)

    Full Text Available BACKGROUND Abdominal wound dehiscence is a preventable complication, but is still seen. When present, it poses problem in the management of the case, increases the morbidity and mortality of the patient. The present study is a prospective study done from January 2010-May 2016 with an objective to find out the incidence of wound dehiscence, the most common pathologies associated with dehiscence and to find out the statistical significance of the difference risk factors causing wound dehiscence and to evaluate the role of tension sutures in prevention of wound dehiscence. MATERIALS AND METHODS 291 major laparotomies were followed from January 2010-September 2016. There were 21 cases of dehiscence and from the remaining 270 cases, 58 patients were chosen as controls who underwent the same procedure, but without dehiscence. 15 factors were analysed and compared between the dehiscence and control groups. RESULTS The incidence was found to be 7.2%. Peritonitis was the most common pathology. The significant factors were age more than 50, wound infection. Tension suture application has shown to reduce the incidence of wound dehiscence. CONCLUSIONS  Intra-abdominal sepsis (peritonitis increases the incidence of wound dehiscence.  Age >50, Uraemic, Jaundiced, Obesity, Malnutrition increases the incidence of wound dehiscence.  Wound infection was a highly significant factor having 8 times more risk of dehiscence.

  14. Spontaneous abdominal wall endometriosis: a case report. (United States)

    Papavramidis, Th S; Sapalidis, K; Michalopoulos, N; Karayanopoulou, G; Raptou, G; Tzioufa, V; Kesisoglou, I; Papavramidis, S T


    Endometriosis is the presence of endometrial glands and stroma outside the uterus. Spontaneous abdominal wall endometriosis (AWE) is any ectopic endometrium found superficial to the peritoneum without the presence of any previous scar. Rarely, endometriosis represents a disease of specific interest to the general surgeon, on account of its extrapelvic localisations. We describe a case with spontaneous AWE presenting as a painful mass with cyclic symptoms. A 28-year-old woman presented to the day-surgery division of our department, suffering from a painful mass in the left lower abdominal quadrant. A mobile mass of 5 x 4 cm was identified. The initial diagnosis was lipoma and excision was planned. During the operation two masses were spotted, very close to one another, and were excised within healthy limits. Pathology revealed endometrial glands surrounded by a disintegrating mantle of endometrial stroma and fibrous scar tissue in which there was a scattering of leucocytes. The woman had no scars. She was discharged from hospital after 2 hours. Two years after the excision she is free of disease and no recurrence has been observed. Spontaneous AWE is rare, accounting for 20% of all AWEs. The triad ; mass, pain and cyclic symptomatology helps in the diagnosis, but unfortunately it is not present in all cases. Spontaneous endometriomas are usually diagnosed by pathology and the treatment of choice is surgical excision.

    Fujiwara H


    Full Text Available To clarify the incidence, background, and progress of hepatic infarction following interventional procedures, cases of hepatic infarction following interventional procedures at our department during the last decade were identified by reviewing the clinical records of 1982 abdominal angiography and interventional procedures and records of abdominal CT. Nine episodes (0.5% in 8 patients were identified as hepatic infarction following an interventional procedure. Five episodes were preceded by embolization of the hepatic or celiac artery at emergency angiography for postoperative bleeding with hemorrhagic shock. Three episodes followed the elected interventional procedure for hepatocellular carcinoma, and the remaining episode occurred after 12 months of chemoinfusion through an indwelling catheter in the hepatic artery and portal vein. Hepatic arterial occlusion in all episodes and portal venous flow abnormality in 5 episodes were observed on angiography. Four patients whose liver function was initially impaired died of hepatic infarction, although the extent of the disease on CT did not appear to be related to the mortality. Multiple risk factors, including arterial insufficiency, were observed in each patient. The incidence of hepatic infarction following interventional procedures in this series was low but sometimes fatal, and occurred most frequently in emergency embolization in hemorrhagic shock.

  16. Abdominal-Pelvic Actinomycosis Mimicking Malignant Neoplasm

    Directory of Open Access Journals (Sweden)

    Teresa Pusiol


    Full Text Available Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.

  17. Fatigue and cardiorespiratory function following abdominal surgery. (United States)

    Christensen, T; Bendix, T; Kehlet, H


    Subjective feelings of fatigue were assessed before operation and 10, 20 and 30 days after uncomplicated elective abdominal surgery in 16 otherwise healthy patients, using a constructed fatigue scale model. In addition, all patients had an orthostatic stress test performed at the same times. Six of the patients also underwent a bicycle ergometer test measuring heart rate and oxygen consumption. Subjective feelings of fatigue were increased (P less than 0.01) at all three postoperative observations, and only 5 of 16 patients returned to their preoperative level. The increased subjective feeling of fatigue correlated positively (RS = 0.53, P less than 0.001) with the increased pulse rate seen during orthostatic stress after operation. Heart rate was about 5 per cent higher (n.s.) after operation when bicycling at the same work loads, while oxygen consumption decreased by about 2 per cent (P less than 0.01) at all three postoperative bicycle tests. It is concluded that even electric uncomplicated abdominal surgery is followed by a pronounced feeling of fatigue, which may persist 1 month after surgery in about one-third of patients. The fatigue scale model seems applicable for future studies on the pathogenesis and treatment of the postoperative fatigue syndrome.

  18. Laparoscopy and Intra-Abdominal Sepsis

    Directory of Open Access Journals (Sweden)



    Full Text Available Context Intra-abdominal sepsis has significant morbidity and mortality. In the developed world, there are many common causes originating from the lower gastrointestinal tract including diverticular disease, appendicitis, perforated cancers, and inflammatory bowel disease. It has a high cost and is associated with high levels of significant morbidity and mortality. Management options include radiologic drainage and surgical options include resection for more widespread sepsis. Laparoscopic surgery has increased and has been useful in elective setting. Its use in the emergency setting is less evaluated. Evidence Acquisition Evidence was acquired by searching online medical databases including Pubmed, Medline and Embase. Results Laparoscopic surgery has been shown to have a role in the acute setting. Studies show it has become the gold standard in the appendicitis. High quality Randomized controlled trials are in short supply but observational and cohort studies have shown equivalence and with increasing experience complication rates are reduced. Evidence is also increasing in the management of diverticular disease, crohn’s and ulcerative colitis as well as post-operative complication management and acute presentations of colorectal cancer. Conclusions Laparoscopic surgery is feasible in the management of intra-abdominal sepsis. It has become the new accepted standard in the management of appendicitis, and is safe, feasible and increasing in the management of complex diverticular disease, acute IBD and colorectal cancer in the emergency and post-operative setting.

  19. The adult abdominal neuromuscular junction of Drosophila: a model for synaptic plasticity. (United States)

    Hebbar, Sarita; Hall, Rachel E; Demski, Sarah A; Subramanian, Aswati; Fernandes, Joyce J


    During its life cycle, Drosophila makes two sets of neuromuscular junctions (NMJs), embryonic/larval and adult, which serve distinct stage-specific functions. During metamorphosis, the larval NMJs are restructured to give rise to their adult counterparts, a process that is integrated into the overall remodeling of the nervous system. The NMJs of the prothoracic muscles and the mesothoracic dorsal longitudinal (flight) muscles have been previously described. Given the diversity and complexity of adult muscle groups, we set out to examine the less complex abdominal muscles. The large bouton sizes of these NMJs are particularly advantageous for easy visualization. Specifically, we have characterized morphological attributes of the ventral abdominal NMJ and show that an embryonic motor neuron identity gene, dHb9, is expressed at these adult junctions. We quantified bouton numbers and size and examined the localization of synaptic markers. We have also examined the formation of boutons during metamorphosis and examined the localization of presynaptic markers at these stages. To test the usefulness of the ventral abdominal NMJs as a model system, we characterized the effects of altering electrical activity and the levels of the cell adhesion molecule, FasciclinII (FasII). We show that both manipulations affect NMJ formation and that the effects are specific as they can be rescued genetically. Our results indicate that both activity and FasII affect development at the adult abdominal NMJ in ways that are distinct from their larval and adult thoracic counterparts

  20. An Intra-Abdominal Pseudocyst around a Ventriculoperitoneal Shunt due to Streptococcus Infection 7 Years after Shunt Surgery

    Arata Tomiyama


    Full Text Available In 1999, a 50-year-old woman underwent ventriculoperitoneal (VP shunt surgery for hydrocephalus after subarachnoid hemorrhage. She was hospitalized for fever and recurrent systemic seizures in November 2006. Head computed tomography (CT showed only old changes. The seizures and fever were controlled by medicinal therapy. However, in December, her consciousness level suddenly decreased, and she showed progressive lower abdominal distension. Head CT showed marked ventriculomegaly, and abdominal CT showed a giant cystic mass at the shunt-tube tip in the lower abdominal cavity. Because thick pus was aspirated from the intra-abdominal mass, we diagnosed the patient with acute obstructive hydrocephalus due to an infected abdominal pseudocyst. Laparotomy and direct cyst drainage were performed, and antibiotic therapy against Streptococcus, the causative pathogen, was administered. The VP shunt tube was replaced. The postoperative course was uneventful, and postoperative CT showed hydrocephalus improvement and no pseudocyst recurrence. Abdominal pseudocysts, which are rare after VP shunt surgeries, usually occur after the subacute postoperative course in younger cerebral hemorrhagic cases. Our case was quite rare because the cyst developed in the chronic phase in an older patient and was caused by streptococcal infection. The cyst components should be examined before cyst drainage when choosing surgical strategies.

    Full Text Available OBJECTIVE AND METHODS: Screening for abdominal aortic aneurysms may be useful to decrease mortality related to rupture. We conducted a study to assess the prevalence of abdominal aortic aneurysms in southern Brazil and to define risk factors associated with high prevalence of this disorder. The screening was conducted using abdominal ultrasound. Three groups were studied: Group 1 - cardiology clinic patients; Group 2 - individuals with severe ischemic disease and previous coronary surgery, or important lesions on cardiac catheterism; Group 3 - individuals without cardiac disease selected from the general population. All individuals were male and older than 54 years of age. The ultrasonographic diagnosis of aneurysm was based on an anteroposterior abdominal aorta diameter of 3 cm, or on an abdominal aorta diameter 0.5 cm greater than that of the supra-renal aorta. RESULTS: A total of 2.281 people were screened for abdominal aortic aneurysms in all groups: Group 1 - 768 individuals, Group 2 - 501 individuals, and Group 3 - 1012 individuals. The prevalence of aneurysms was 4.3%, 6.8% and 1.7%, respectively. Age and cigarette smoking were significantly associated with increased prevalence of aneurysms, as was the diagnosis of peripheral artery disease. DISCUSSION: We concluded that screening may be an important tool to prevent the mortality associated with abdominal aortic aneurysms surgery. Additionally, the cost of screening can be decreased if only individuals presenting significant risk factors, such as coronary and peripheral artery disease, smokers and relatives of aneurysm patients, are examined.OBJETIVO E MÉTODOS: O rastreamento de aneurisma da aorta abdominal infra-renal é importante pois pode diminuir a mortalidade relacionada à ruptura.

    Objective To evaluate the effects of supplementation of glutamine (GLN) on maintaining glutathione (GSH) level, immune system function, liver function, and clinical outcome of patients receiving abdominal operation. Methods Forty patients undergoing elective abdominal surgical treatment were randomly divided into 2 groups: study group (n = 20) and control group (n = 20). All patients received total parenteral nutrition (TPN) for up to 7 days during perioperative period. The study group received TPN supplemented with GLN dipeptide while the control group received TPN without GLN dipeptide. Patients in both groups received equivalent nitrogen and caloric intake. Blood sample was taken on preoperative day, and the 1st, 3rd, 6th postoperative day to measure GSH level, immune indexes, and liver function indexes. Results The decrease of GSH level in plasma and red blood cell (RBC) in study group was less than that in control group during postoperative period. Ratio of GSH/glutathione disulfide (GSSG) in plasma in study group was higher than that in control group on the 3rd postoperative day (52.53 ± 11.46 vs. 31.43 ± 7.27, P = 0.001). Albumin level in study group was higher than that in control group on the 3rd postoperative day (37.7 ± 3.8 g/L vs. 33.8 ± 4.2 g/L, P = 0.02). There was no significant difference in the levels of immunoglobin (IgG, IgM, IgA) or T lymphocyte subgroup (CD4, CD8, CD4/CD8) in both groups during postoperative period. There was one case with infectious complication in control group, while none in study group. A trend of shortened hospital stay was observed in study group compared with control group (22.3 ± 2.1 d vs. 24.9 ± 1.7 d, P = 0.32). Conclusions Supplementation of GLN-enriched TPN has beneficial effects on maintaining GSH levels in plasma and RBC, sustaining GSH/GSSG ratio and albumin level, and keeping antioxidant abilities during postoperative period in patients with abdominal operation, with the trends of decreasing incidence of

  3. Fiber architecture of canine abdominal muscles. (United States)

    Boriek, Aladin M; Ortize, Jaime; Zhu, Deshen


    During respiration, abdominal muscles experience loads, not only in the muscle-fiber direction but also transverse to the fibers. We wondered whether the abdominal muscles exhibit a fiber architecture that is similar to the diaphragm muscle, and, therefore, we chose two adjacent muscles: the internal oblique (IO), with about the same muscle length as the diaphragm, and the transverse abdominis (TA), which is twice as long as the diaphragm. First, we used acetylcholinesterase staining to examine the distribution of neuromuscular junctions on both surfaces of the TA and IO muscles in six dogs. A maximum of four irregular bands of neuromuscular junctions crossed the IO, and as many as six bands crossed the TA, which is consistent with a discontinuous fiber architecture. In six additional dogs, we examined fiber architecture of these muscles by microdissecting 103 fascicles from the IO and 139 from the TA. Each fascicle contained between 20 and 30 muscle fibers. The mean length of nonspanning fibers (NSF) ranged from 2.8 +/- 0.3 cm in the IO to 4.3 +/- 0.5 cm in the TA, and the mean length of spanning fibers ranged from 4.3 +/- 0.5 cm in the IO to 7.6 +/- 1.4 cm in the TA. NSF accounted for 89.6 +/- 1.5% of all fibers dissected from the IO and 99.1 +/- 0.2% of all fibers dissected from the TA. The percentage of NSF with both ends tapered was 6.2 +/- 1.0 and 41.0 +/- 2.3% for IO and TA, respectively. These data show that fiber architecture in either IO or TA is discontinuous, with much more short-tapered fibers in the TA than in the IO. When abdominal muscles are submaximally activated, as during both normal expiration and maximal expiratory efforts, muscle force could be transmitted to the cell membrane and to the extracellular intramuscular connective tissue by shear linkage, presumably via structural transmembrane proteins.

  4. Recent advances in equine abdominal surgery. (United States)

    Smith, C L; Dowling, B A; Dart, A J


    Laparoscopy is a minimally invasive procedure that has applications as a diagnostic, therapeutic and prognostic technique. Specialized equipment is necessary to perform equine laparoscopy, and there is a large range of instruments, both disposable and non-disposable available. Laparoscopic procedures described include ovariectomy, cryptorchidectomy, adhesiolysis and herniorrhaphy. Laparoscopy can be performed in a standing or dorsally recumbent position, depending on surgeon preference, patient status and the procedure to be performed. Stapling equipment is frequently used in gastrointestinal surgery in horses. Advantages include decreased surgical time and a decrease in the risk of contamination. Stapling equipment is often used in creating anastomoses, both in the large and small intestines, as well as in vessel ligation. New surgical techniques intended to decrease adhesion formation include the use of carboxymethylcellulose and bioresorbable patches. Indwelling abdominal drains can be used for peritoneal lavage following surgery and also appear to decrease the risk of adhesion formation. Improvements in post-operative care, including the treatment of post-operative ileus and endotoxaemia can significantly improve the outcome of horses that have undergone surgery for abdominal disorders. Recommendations for the use of prokinetic agents in horses with ileus vary widely. Prokinetic agents include local anaesthetics, macrolide antimicrobials, cholinergic agonists and dopamine antagonists. Endotoxaemia is common in horses following surgery for gastrointestinal disorders. The antibiotic polymyxin B binds to the circulating endotoxin molecule, decreasing its half-life in the intra-vascular space and reducing associated inflammation. This drug appears to be an effective and affordable treatment option for horses with endotoxaemia. The use of specific cyclooxygenase inhibitors in veterinary medicine have been studied recently. Selective cyclooxygenase-2 inhibitors may

    BACKGROUND: Hemoperitoneum is associated with several emergency conditions and is especially evident when it occurs in patients with liver cirrhosis. This study aimed to assess the clinical characteristics of cirrhotic patients who did not have abdominal trauma or tumor but who developed hemoperitoneum. METHODS: Wereviewedtheclinicalrecordsof1276consecutive cirrhotic patients with hemoperitoneum at our center between January 2007 and December 2009. Hemoperitoneum was confirmed by abdominal paracentesis. RESULTS: Of the 1276 cirrhotic patients, 19 were found to have hemoperitoneum, but only 6 did not have abdominal trauma or tumor. The occurrence of spontaneous hemoperitoneum in the cirrhotic patients was therefore 0.5%. Hemoperitoneum can occur spontaneously in severely decompensated cirrhotic patients with intra-abdominal collateral vessels and high scores on the model for end-stage liver disease and Child-Pugh-Turcotte test. Most patients presented with abdominal distension, abdominal pain, increased abdominal girth and hemodynamic instability with a significant drop in the hemoglobin level. Three patients died of hemorrhagic shock within 24 hours, and the other 3 died of hepatic encephalopathy or spontaneous bacterial peritonitis after 5 to 10 days because of further decompensation of the liver. CONCLUSIONS: Hemoperitoneum can occur in cirrhotic patients who do not have abdominal trauma or tumor. It mainly occurs in severely decompensated end-stage cirrhotic patients. Cirrhotic patients with hemoperitoneum have a poor prognosis.

  2. An unusual cause of abdominal pain.

    LENUS (Irish Health Repository)

    Mc Cabe, Aileen


    A 26-year-old man presented to the Emergency Department with abdominal pain, diarrhoea, anorexia and haematemesis. The patient was previously diagnosed with latent tuberculosis (TB). On examination, his abdomen was diffusely tender, with localised guarding in the right iliac fossa. CT imaging of his abdomen and pelvis demonstrated a low volume of ascites, diffuse studding of the peritoneum, omental caking and several bulky low-density lymph nodes in the retroperitoneum. A laparoscopy was performed to obtain a peritoneal biopsy. Histology demonstrated fragments of peritoneum with necrotising granulomatous inflammatory infiltrate in keeping with an infectious process, favouring TB. He was commenced on rifampicin, isoniazid, pyrazinamide, ethambutol and pyridoxine under the direct observed therapy by the infectious diseases team. In view of his extensive peritoneal involvement, he was empirically started on high-dose prednisolone for symptomatic control and to reduce complications related to peritoneal adhesions.

  3. Retroperitoneal abscess: an extra-abdominal manifestation. (United States)

    Mallia, Alvin James; Ashwood, Neil; Arealis, George; Galanopoulos, Ilias


    Retroperitoneal abscesses are unusual occurrences with occult and insidious presentations. There is often a lack of abdominal signs, leading to delays in drainage and high mortality rates. We report a case of thigh emphysema in an 88-year-old patient with diabetes. Prior to admission the patient reported a vague 4-week history of left thigh pain and an inability to fully weight bear. She presented to our emergency department with sepsis and acute kidney impairment. An X-ray of her left femur revealed widespread gas between muscular planes. A retroperitoneal abscess involving the left renal fossa, psoas, iliacus and upper thigh muscles was revealed on an urgent CT scan. The patient was transferred to intensive care unit (ICU) and underwent an emergency drainage. Despite ICU the patient died 2 days after admission.

    Zissin, R.; Osadchy, A. [Sapir Medical Center, Dept. of Diagnostic Imaging, Kfar Saba (Israel)]. E-mail:; Gayer, G. [Assaf Harofe Medical Center, Dept. of Diagnostic Imaging, Zrifin (Israel)


    Despite progress in surgical techniques and modern medical treatment, postoperative complications occur not infrequently and vary according to type of surgery, clinical setting, and time elapsed since surgery. In general, they can be divided into early and delayed complications. Delayed postoperative complications can be classified as specific and nonspecific. The common nonspecific delayed complications are incisional hernia and postoperative bowel obstruction. Bowel obstruction can be further categorized as obstruction related to benign or neoplastic etiology, the latter occurring in oncology patients in whom the primary surgery was related to an underlying abdominal neoplasm. Gossypiboma is another, fortunately rare, postoperative complication. Specific complications appear after specific operations and include the following: Splenosis - following splenectomy. Retained gallstones and spilled gallstones - following cholecystectomy, mainly laparoscopic. Dropped appendicolith and stump appendicitis - following appendectomy, mainly laparoscopic. Obturation obstruction by a bezoar - following gastric surgery. Afferent loop syndrome (ALS) - following Bilroth II gastrectomy. (author)

  7. Abdominal vascular syndromes: characteristic imaging findings* (United States)

    Cardarelli-Leite, Leandro; Velloni, Fernanda Garozzo; Salvadori, Priscila Silveira; Lemos, Marcelo Delboni; D'Ippolito, Giuseppe


    Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital-including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)-or compressive-including "nutcracker" syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome. In this article, we aimed to illustrate imaging findings that are characteristic of these syndromes, through studies conducted at our institution, as well as to perform a brief review of the literature on this topic.

  8. Standardized anatomic space for abdominal fat quantification (United States)

    Tong, Yubing; Udupa, Jayaram K.; Torigian, Drew A.


    The ability to accurately measure subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) from images is important for improved assessment and management of patients with various conditions such as obesity, diabetes mellitus, obstructive sleep apnea, cardiovascular disease, kidney disease, and degenerative disease. Although imaging and analysis methods to measure the volume of these tissue components have been developed [1, 2], in clinical practice, an estimate of the amount of fat is obtained from just one transverse abdominal CT slice typically acquired at the level of the L4-L5 vertebrae for various reasons including decreased radiation exposure and cost [3-5]. It is generally assumed that such an estimate reliably depicts the burden of fat in the body. This paper sets out to answer two questions related to this issue which have not been addressed in the literature. How does one ensure that the slices used for correlation calculation from different subjects are at the same anatomic location? At what anatomic location do the volumes of SAT and VAT correlate maximally with the corresponding single-slice area measures? To answer these questions, we propose two approaches for slice localization: linear mapping and non-linear mapping which is a novel learning based strategy for mapping slice locations to a standardized anatomic space so that same anatomic slice locations are identified in different subjects. We then study the volume-to-area correlations and determine where they become maximal. We demonstrate on 50 abdominal CT data sets that this mapping achieves significantly improved consistency of anatomic localization compared to current practice. Our results also indicate that maximum correlations are achieved at different anatomic locations for SAT and VAT which are both different from the L4-L5 junction commonly utilized.

  9. Abdominal and pelvic computed tomography (CT) interpretation: discrepancy rates among experienced radiologists

    Energy Technology Data Exchange (ETDEWEB)

    Abujudeh, Hani H.; Boland, Giles W.; Kaewlai, Rathachai; Rabiner, Pavel; Thrall, James H. [Massachusetts General Hospital and Harvard Medical School, Department of Radiology, Boston, MA (United States); Halpern, Elkarn F.; Gazelle, G.S. [Massachusetts General Hospital and Harvard Medical School, Department of Radiology, Boston, MA (United States); Massachusetts General Hospital and Harvard Medical School, Institute for Technology Assessment, Boston, MA (United States)


    To assess the discrepancy rate for the interpretation of abdominal and pelvic computed tomography (CT) examinations among experienced radiologists. Ninety abdominal and pelvic CT examinations reported by three experienced radiologists who specialize in abdominal imaging were randomly selected from the radiological database. The same radiologists, blinded to previous interpretation, were asked to re-interpret 60 examinations: 30 of their previous interpretations and 30 interpreted by others. All reports were assessed for the degree of discrepancy between initial and repeat interpretations according to a three-level scoring system: no discrepancy, minor, or major discrepancy. Inter- and intrareader discrepancy rates and causes were evaluated. CT examinations included in the investigation were performed on 90 patients (43 men, mean age 59 years, SD 14, range 19-88) for the following indications: follow-up/evaluation of malignancy (69/90, 77%), pancreatitis (5/90, 6%), urinary tract stone (4/90, 4%) or other (12/90, 13%). Interobserver and intraobserver major discrepancy rates were 26 and 32%, respectively. Major discrepancies were due to missed findings, different opinions regarding interval change of clinically significant findings, and the presence of recommendation. Major discrepancy of between 26 and 32% was observed in the interpretation of abdominal and pelvic CT examinations. (orig.)

  10. Abdominal muscle activity during breathing with and without inspiratory and expiratory loads in healthy subjects. (United States)

    Mesquita Montes, António; Baptista, João; Crasto, Carlos; de Melo, Cristina Argel; Santos, Rita; Vilas-Boas, João Paulo


    Central Nervous System modulates the motor activities of all trunk muscles to concurrently regulate the intra-abdominal and intra-thoracic pressures. The study aims to evaluate the effect of inspiratory and expiratory loads on abdominal muscle activity during breathing in healthy subjects. Twenty-three higher education students (21.09±1.56years; 8males) breathed at a same rhythm (inspiration: two seconds; expiration: four seconds) without load and with 10% of the maximal inspiratory or expiratory pressures, in standing. Surface electromyography was performed to assess the activation intensity of rectus abdominis, external oblique and transversus abdominis/internal oblique muscles, during inspiration and expiration. During inspiration, transversus abdominis/internal oblique activation intensity was significantly lower with inspiratory load when compared to without load (p=0.009) and expiratory load (p=0.002). During expiration, the activation intensity of all abdominal muscles was significantly higher with expiratory load when compared to without load (pmuscle to modulate the intra-abdominal pressure for the breathing mechanics.

  11. Gastroesophageal reflux in children with recurrent abdominal pain. (United States)

    van der Meer, S B; Forget, P P; Kuijten, R H; Arends, J W


    In this study we investigated the presence of gastroesophageal reflux in children with recurrent abdominal pain and its possible relationship to food intolerance-associated duodenal inflammation. Twenty-four-hour intra-esophageal pH monitoring, an endoscopic duodenal biopsy and a small bowel 51Cr-EDTA permeability test were performed in 25 children with recurrent abdominal pain. In 14 cases (56%) the pH monitoring was abnormal, pointing to the presence of pathological gastroesophageal reflux. Treatment of gastroesophageal reflux in the latter patients resulted in resolution or improvement of abdominal pain in 10 cases (71%). Gastroesophageal reflux did not appear to be associated with either intestinal permeability to 51Cr-EDTA or duodenal biopsy findings. We conclude that pathological gastroesophageal reflex is a frequent finding in children with recurrent abdominal pain, that it is unrelated to duodenal inflammation and that there might be a causal relationship between pathological gastroesophageal reflux and recurrent abdominal pain in children.

    Puch-Ceballos, Eduardo Erik; Vázquez-Castro, Rosbel; Osorio-Pérez, Ana Isabel; Ramos-Ayala, Montserrat; Villarreal-Sosa, Conrado Otoniel; Ruvalcaba-Rivera, Everardo


    Abdominal ectopic pregnancy is an extremely rare entity, which represents 1% of all ectopic pregnancies and is associated with high maternal and fetal morbidity and mortality. The maternal mortality risk of an abdominal ectopic pregnancy is seven to eight times greater than the risk of a tubal ectopic pregnancy and is 90 times greater than the risk of intrauterine pregnancy. This is a disease of difficult diagnosis that often takes place late. We report the case of a patient with an abdominal ectopic pregnancy, which was diagnosed by abdominal ultrasound in the second trimester; the patient was suc- cessfully treated with exploratory laparotomy with complete removal of the fetus and placenta. We provide a review of the literature on the risk factors for abdominal ectopic pregnancy, diagnostic tests and therapeutic options.

    Objective: Uterus-to-abdominal-wall fistula is a very rare complication after uterine-incision delivery over the last decades. It can even lead to death. Mainly, the fistula occurs when big tension and critical infection exist within the incision of uterus and abdominal wall. Methods: The authors described the clinical presentation, pathology of uterus-to-abdominal-wall fistula, and reported their experience in 6 cases who underwent Z-plasty operation for this rare complication from January 1998 to January 2008. Results: All flaps survived completely and all the wounds in abdominal walls healed very well. The six cases were followed up for 1 to 5 years, and no fistula recurrence occurred. Conclusion: Z-plasty technique is a very simple and efficient approach to repair uterus to abdominal fistula after uterine-incision delivery.

  14. A New Etiology for the Abdominal Compartment Syndrome: Pseudomyxoma Peritonei

    Directory of Open Access Journals (Sweden)

    Charles Sabbagh


    Full Text Available Pseudomyxoma peritonei (PMP is a rare diagnosis with an incidence of 1-2 per million. Most cases originate from an appendix which ruptures and releases mucin into the peritoneal cavity. The progression of the disease results in obstruction and cutaneous leak. Abdominal compartment syndrome is an uncommon complication of peritoneal pseudomyxoma. In the present article, we report the case of a patient with PMP and abdominal compartment syndrome. A laparotomy to decrease the abdominal pressure was performed. Three months later, a peritonectomy with hyperthermic intraperitoneal chemotherapy was performed. The patient was still alive 1 year after the procedure without any recurrence. In conclusion, acute abdominal pain and respiratory failure in patients with peritoneal PMP should lead to the measurement of the abdominal pressure but are not a contra indication for curative treatment of PMP.

    Kris T Chiles


    Full Text Available A 48 year old male admitted to the intensive care unit after a cardiac arrest complicated by a stroke intra-operatively during automatic implantable cardioverter defibrillator placement. He post-operatively developed a rigid abdomen, elevated peak and plateau pressures, hypoxia and renal insufficiency. He was diagnosed with abdominal compartment syndrome with an intra-abdominal compartment pressure of 40mmHg. The patient was administered 10 mg of intravenous cisatracuriumbesylate in preparation for bedside surgical abdominal decompression. Cisatracurium eliminated the patients need for surgical intervention by reducing his abdominal compartment pressures to normal and improving his hypoxia and renal function. This case illustrates that neuromuscular blockade should be attempted in patients with abdominal compartment syndrome prior to surgical intervention.

    AIM: To evaluate the therapeutic effects of abdominal decompression plus continuous regional arterial infusion (CRAI) via a drug delivery system (DDS) in severe acute pancreatitis (SAP) patients with abdominal compartment syndrome (ACS).METHODS: We presented our recent experience in 8 patients with SAP. The patients developed clinical ACS, which required abdominal decompression. During the operation, a DDS was inserted into the peripancreatic artery (the catheter was inserted from the right gastroepiploic artery until it reached the junction between the pancreaticoduodenal and gastroduodenal artery). Through this DDS, a protease inhibitor, antibiotics and octreotide were infused continuously. The duration of the regional artery infusion ranged from 8 to 41 d. The outcomes and the changes in the APACHE Ⅱ score, computed tomography (CT) severity index and intra-abdominal pressure (IAP) of the patients were retrospectively evaluated.RESULTS: Eight patients with an initial APACHE Ⅱscore of 18.9 (range, 13-27) and a Balthazar CT severity index of 9.1 (range, 7-10) developed severe local and systemic complications. These patients underwent subsequent surgical decompression and CRAI therapy because of intra-abdominal hypertension (IAH). After a mean interval of 131.9 ± 72.3 d hospitalization, 7 patients recovered with decreased APACHE Ⅱ scores, CT severity indexes and IAP. The mean APACHE Ⅱ score was 5.4 (range, 4-8), the CT severity index was 2.3 (range, 1-3), and IAP decreased to 7.7 mmHg (range,6-11 mmHg) 60 d after operation. One patient died of multiple organ failure 1 wk after surgery.CONCLUSION: CRAI and laparotomic decompression might be a therapeutic option for SAP patients with ACS.

    Full Text Available BACKGROUND: Incidence of postoperative pulmonary complications (PPC in patients undergoing non-cardiothoracic surgery remains high and the occurrence of these complications has enormous implications for the patient and the health care system. AIM: The aim of the study was to identify risk factors for PPC in patients undergoing abdominal surgical procedures. MATERIALS AND METHODS: A prospective cohort study in abdominal surgical patients, admitted to the emergency and surgical ward of the UHC of Tirana, Albania, was conducted during the period: March 2014-March 2015. We collected data on the occurrence of a symptomatic and clinically significant PPC using clinical, laboratory, and radiology data. We evaluated the relations between PPCs and various pre-operative or intra-operative factors to identify risk factors. RESULTS: A total of 450 postoperative patients admitted to the surgical emergency and surgical ward were studied. The mean age were 59.85 ±13.64 years with 59.3% being male. Incidence of PPC was 27.3% (123 patients and hospital length of stay was 4.93 ± 4.65 days. Length of stay was substantially prolonged for those patients who developed PPC (7.48 ± 2.89 days versus 3.97± 4.83 days, p 2 (OR 6.37; 95% CI: 1.54-26.36, P = 0.01. CONCLUSION: We must do some efforts in reducing postoperative pulmonary complications, firstly to identify which patients are at increased risk, and then following more closely high-risk patients because those patients are most likely to benefit.

    Edivaldo Massazo Utiyama


    Full Text Available OBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years; 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

  20. Blunt abdominal trauma: The role of focused abdominal sonography in assessment of organ injury and reducing the need for CT

    Directory of Open Access Journals (Sweden)

    Samer Malak Boutros


    Conclusion: Ultrasonography is considered the best modality in initial evaluation of blunt abdominal trauma patients as it is noninvasive, readily available, and requires minimal preparation time. Ultrasonography is very useful in follow up of patients with intra-abdominal injury and decreases use of CT which has the disadvantages of being expensive, high dose radiation.

  1. Changes in lateral abdominal muscles' thickness immediately after the abdominal drawing-in maneuver and maximum expiration. (United States)

    Ishida, Hiroshi; Watanabe, Susumu


    All lateral abdominal muscles contract more strongly during maximum expiration than during the abdominal drawing-in maneuver (ADIM). However, little is known about which of the lateral abdominal muscles is activated during maximum expiration. Thus, the purpose of this study is to quantify changes in the thickness of the lateral abdominal muscles immediately after the ADIM and maximum expiration. The thickness of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles was measured by ultrasound imaging in 30 healthy men before and after the ADIM and maximum expiration. After the ADIM, there was no significant change in the thickness of the lateral abdominal muscles. After maximum expiration, the thickness of the TrA muscle significantly increased, and there was no significant change in the thickness of the IO and EO muscles. Thus, maximum expiration may be an effective method for TrA, rather than IO and EO, muscle training.

  2. A kinematic comparison of four abdominal training devices and a traditional abdominal crunch. (United States)

    Sands, William A; McNeal, Jeni R


    Abdominal exercises are often performed on roller or rocker mechanisms, which have been aggressively promoted through the television and print media. However, justifications are lacking as to why these devices are superior to traditional abdominal exercises such as crunches. This study sought to describe and compare the range of motion (ROM) of several joints during crunches performed on 4 different abdominal conditioning devices (2 roller and 2 pivot types) and a traditional crunch exercise. Ten men (29 +/- 5.87 years, 177.5 +/- 6.46 cm, 80.96 +/- 11.72 kg) and 10 women (33.4 +/- 10.16 years, 162.23 +/- 3.83 cm, 56.99 +/- 7.36 kg) subjects agreed to participate in the study. Subjects were videotaped in the sagittal plane (60 Hz) using standard kinematic methods. Reflective markers were placed on the right temple, auditory meatus, shoulder, hip, knee, ankle, heel, toe, and 2 sternum markers placed on a foam piece strapped to the subject's chest. The videotaped movements were automatically digitized (PEAK5 2-D) and the data smoothed using a Butterworth filter. Relative angular ROMs of the head (temple, auditory meatus, shoulder); neck (auditory meatus, shoulder, hip); trunk (near sternum, shoulder, hip); hip (shoulder, hip, knee); sternum/head (sternum near and sternum far with temple and auditory meatus); sternum/trunk (sternum near and sternum far with shoulder and hip); and a sum of 4 angles (head, neck, trunk, hip) were calculated. Sex by equipment repeated measures analyses of variance (ANOVAs) were calculated on the angles of the 5 exercises. When no main effect for sex was found, the data were collapsed across sex and a one-way ANOVA with repeated measures was calculated on the resulting data. Post hoc analyses of pairwise differences were calculated using Tukey's honestly significant difference statistic. Results showed that crunches performed with the abdominal devices resulted in less ROM in all angles measured when compared with a traditional crunch. The

  3. Development of a new illumination procedure for photodynamic therapy of the abdominal cavity (United States)

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


    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.

  4. Thoraco-abdominal coordination and performance during uphill running at altitude (United States)

    Bernardi, Eva; Pratali, Lorenza; Mandolesi, Gaia; Spiridonova, Maria; Roi, Giulio Sergio; Cogo, Annalisa


    Introduction Running races on mountain trails at moderate-high altitude with large elevation changes throughout has become increasingly popular. During exercise at altitude, ventilatory demands increase due to the combined effects of exercise and hypoxia. Aim To investigate the relationships between thoraco-abdominal coordination, ventilatory pattern, oxygen saturation (SpO2), and endurance performance in runners during high-intensity uphill exercise. Methods Fifteen participants (13 males, mean age 42±9 yrs) ran a “Vertical Kilometer,” i.e., an uphill run involving a climb of approximately 1000 m with a slope greater than 30%. The athletes were equipped with a portable respiratory inductive plethysmography system, a finger pulse oximeter and a global positioning unit (GPS). The ventilatory pattern (ventilation (VE), tidal volume (VT), respiratory rate (RR), and VE/VT ratio), thoraco-abdominal coordination, which is represented by the phase angle (PhA), and SpO2 were evaluated at rest and during the run. Before and after the run, we assessed respiratory function, respiratory muscle strength and the occurrence of interstitial pulmonary edema by thoracic ultrasound. Results Two subjects were excluded from the respiratory inductive plethysmography analysis due to motion artifacts. A quadratic relationship between the slope and the PhA was observed (r = 0.995, p = 0.036). When the slope increased above 30%, the PhA increased, indicating a reduction in thoraco-abdominal coordination. The reduced thoraco-abdominal coordination was significantly related to reduced breathing efficiency (i.e., an increased VE/VT ratio; r = 0.961, p = 0.038) and SpO2 (r = -0.697, pabdominal coordination and consequent reduction in SpO2 were associated with interstitial pulmonary edema. Conclusion Reductions in thoraco-abdominal coordination are associated with a less efficient ventilatory pattern and lower SpO2 during uphill running. This fact could have a negative effect on performance

  5. A comparison of abdominal and vaginal hysterectomies in Benghazi, Libya. (United States)

    Agnaeber, K; Bodalal, Z


    We performed a comparative study between abdominal and vaginal hysterectomies using clinical data from Al-Jamhouria hospital (one of the largest maternity hospitals in Eastern Libya). Various parameters were taken into consideration: the rates of each type (and their subtypes); average age of patients; indications; causes; postoperative complications; and duration of stay in the hospital afterwards. Conclusions and recommendations were drawn from the results of this study. In light of the aforementioned parameters, it was found that: (1) abdominal hysterectomies were more common than vaginal hysterectomies (p < 0.001); (2) patients admitted for abdominal hysterectomies are younger than those admitted for vaginal hysterectomies (p < 0.001); (3) the most common indication for an abdominal hysterectomy was menstrual disturbances, while for vaginal hysterectomies it was vaginal prolapse; (4) the histopathological cause for abdominal and vaginal hysterectomies were observed and the most common were found to be leiomyomas and atrophic endometrium; (5) there was no significant difference between the two routes in terms of postoperative complications; (6) patients who were admitted for abdominal hysterectomies spent a longer amount of time in the hospital (p < 0.01). It was concluded that efforts should be made to further pursue vaginal and laparoscopic hysterectomies as a viable option to the more conventional abdominal route.

  6. Abdominal circumference contributes to absence of wasting in Brazilian children. (United States)

    César, J A; Victora, C G; Morris, S S; Post, C A


    A number of population groups in Latin America show high prevalences of stunting (low height-for-age) despite very low rates of wasting (weight-for-height deficits). One possible explanation for this phenomenon is an increase in abdominal circumference, which would affect children's weights but not their heights. This study was designed to describe the abdominal circumferences of a group of poor children from Northeast Brazil, and to relate these to their weight-for-weight z-score. Children (n = 252) participating in a government growth monitoring program were studied. The prevalence of stunting (below -2 SD) was 26.2%, but only 1.2% were wasted. Abdominal circumferences increased with age up to 36 mo, followed by a slight decline after 48 mo. Abdominal circumference was the anthropometric measurement most closely associated with weight-for-height, with a coefficient of determination of 41%. Even after adjusting for arm circumference, abdominal circumference continued to explain 16% of the variation in weight-for-height. Despite slight differences in measurement techniques, the study children had consistently larger abdominal girths than a sample of North American children. These findings must be verified by replication but highlight a possible contribution of abdominal circumference in the determination of levels of wasting.

  7. Abdominal expiratory muscle activity in anesthetized vagotomized neonatal rats. (United States)

    Iizuka, Makito


    The pattern of respiratory activity in abdominal muscles was studied in anesthetized, spontaneously breathing, vagotomized neonatal rats at postnatal days 0-3. Anesthesia (2.0% isoflurane, 50% O(2)) depressed breathing and resulted in hypercapnia. Under this condition, abdominal muscles showed discharge late in the expiratory phase (E2 activity) in most rats. As the depth of anesthesia decreased, the amplitude of discharges in the diaphragm and abdominal muscles increased. A small additional burst frequently occurred in abdominal muscles just after the termination of diaphragmatic inspiratory activity (E1 or postinspiratory activity). Since this E1 activity is not often observed in adult rats, the abdominal respiratory pattern likely changes during postnatal development. Anoxia-induced gasping after periodic expiratory activity without inspiratory activity, and in most rats, abdominal expiratory activity disappeared before terminal apnea. These results suggest that a biphasic abdominal motor pattern (a combination of E2 and E1 activity) is a characteristic of vagotomized neonatal rats during normal respiration.

  8. The influence of reamberin on oxygen balance, oxidative stress and lung dysfunction in patients with abdominal sepsis

    Directory of Open Access Journals (Sweden)

    A. B. Tolkach


    Full Text Available The investigation was dedicated to the exploration of reamberin influence on oxidative stress and metabolic disturbances in 64 patients with abdominal sepsis. The authors used reamberin for correction of oxidative processes and metabolic disturbances for treatment of the patients with abdominal sepsis. The authors registered that reamberin improved the oxygen-transport function of the blood and metabolic processes during the abdominal sepsis via the hybernation condition — a form of adaptive reaction of organs and systems during the endotoxemia for creation of more effective environment for functioning of main organs and the whole organism. The authors show that the main pathogenetic mechanisms for multiorgan dysfunction are metabolic disturbances and energy deficiency in organs and systems with subsequent tissue hypoxia.

  9. Bullhorn hernia: A rare traumatic abdominal wall hernia

    Directory of Open Access Journals (Sweden)

    Bimaljot Singh


    Full Text Available Traumatic abdominal wall hernia (TAWH is rare despite the high prevalence of blunt abdominal trauma. Bullhorn hernia occurs as a result of a direct blow to the abdominal wall by the horn of a bull, which disrupts the muscles and fascia and leads to hernia formation. We report a rare case of bullhorn TAWH in a 70-year-old patient who presented with swelling at the left lumbar region. The patient was managed by immediate surgical intervention. A surgeon must have high index of suspicion for the diagnosis of this condition as missed hernias in this setting pose a high risk of strangulation and gangrene.

    Full Text Available Epiploic appendagitis (EA is an uncommon cause of abdominal pain. It is a benign condition but may mimic other serious causes of acute abdomen such as appendicitis, diverticulitis, and gynecological emergency in severe cases. Knowledge of this condition in the differential diagnosis of abdominal pain can save unnecessary hospital admission, antibiotics, and surgery. In this article, we present the case of a 43-year-old female who presented to our hospital with a 2-day history of right lower quadrant abdominal pain and diarrhea. She was diagnosed with EA with computed tomography of abdomen with contrast and was managed conservatively with good outcome.

    Full Text Available Abstract Background Desmoid tumors are slow growing deep fibromatoses with aggressive infiltration of adjacent tissue but without any metastatic potential. Case Presentation We report on two female patients with desmoid tumor of the abdominal wall who underwent primary resection. Both patients had a history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, magnetic resonance imaging and computed tomography. The histology in both cases revealed a desmoid tumor. Conclusion Complete surgical resection is the first line management of this tumor entity.

  13. Fournier's gangrene secondary to intra-abdominal processes. (United States)

    Gerber, G S; Guss, S P; Pielet, R W


    We report 2 cases of necrotizing fasciitis of the perineum, perianal area, and male genitalia (Fournier's gangrene) that arose secondary to intra-abdominal infectious processes (ruptured appendicitis and diverticulitis). Management consisted of immediate debridement of necrotic tissue, exploratory laparotomy, and diverting colostomy. The presence of an acute abdominal process was not immediately evident on initial evaluation of either patient. This demonstrates the critical importance of considering intra-abdominal infection in patients with Fournier's gangrene when the more commonly seen urinary tract, perirectal, and traumatic causes are not readily apparent.

    Full Text Available CONTEXT: The lithopedion (calcified abdominal pregnancy is a rare phenomenon and there are less than 300 cases reported in the medical literature. CASE REPORT: In this case, a 40 year-old patient had had her only pregnancy 18 years earlier, without medical assistance since then. She came to our hospital with pain and tumoral mass of approximately 20 centimeters in diameter. Complementary examinations (abdominal X-ray, ultrasonography and computerized tomography demonstrated an extra-uterine abdominal 31-week pregnancy with calcification areas. Exploratory laparotomy was performed, with extirpation of a well-conserved fetus with partially calcified ovular membranes.

    Full Text Available Synovial sarcoma (SS is a malignant mesenchymal neoplasm which commonly occurs in the extremities in close association with tendon sheaths, bursae, joint capsules, and fascial structures. Rarely, SS may be present in unexpected location such as the abdominal wall. Surgical resection with wide margins is the initial standard treatment; however, a multimodal approach including radiotherapy and chemotherapy is often favored. Here, we present a case of SS of the anterior abdominal wall in a 14-year-old patient with a right upper abdominal lump. He underwent wide surgical excision and has received adjuvant chemotherapy. He is doing well on follow-up of six months.

  16. Fetal weight estimation by ultrasonic measurement of abdominal circumference. (United States)

    Kearney, K; Vigneron, N; Frischman, P; Johnson, J W


    The purpose of this study was to compare ultrasonic measurements of fetal abdominal circumference to ultrasonic measurements of fetal biparietal diameter, as a means of estimating fetal body weight. Of 58 fetuses who had abdominal circumferences measured, 48 (82%) of the predicted weights were within 15% of the actual birth weights. Forty-four of the same 58 fetuses had satisfactory biparietal diameter measurements, but only 21 (48%) of the predicted weights were within 15% of the actual birthweights. Ultrasonic measurement of abdominal circumference appears to be a more reliable index of fetal body weight than other currently available techniques.

    R. V. Garyaev


    Full Text Available A prospective randomized clinical trial was performed in 100 patients who underwent abdominal hysterectomy under endotracheal anesthesia based on sevoflurane and fentanyl. Intraoperatively, ketorolac 30 mg was administered intramuscularly after induction of anesthesia and paracetamol 1 g was injected intravenously 30–40 minutes prior to surgical termination in a control group (n = 25. For postoperative anal- gesia, promedol, tramadol, and ketorolac were used intramuscularly and paracetamol was given intravenously. Three study groups (n = 2 in each differed from the control group in that during wound suturing a multiperforated catheter was placed above the peritoneum over a length of 15 cm, through which a 10-ml bolus of 0.75 % ropivacaine was first administered, followed by continuous infusion of 0.2 % ropivacaine at a rate of 8 ml/hour for 36 hours. In one irrigation group, ketorolac 30 mg was injected intramuscularly t.i.d. for 2 days; in another group, the agent was added to a ropivacaine solution calculated with reference to 180 mg for 2 days; in the third group, ketoprofen 100 mg instead of ketorolac was used b.i.d. for 2 days. Pain level (by digital rating scale, 0–10 and the need for analgesics were measured. There was no sta- tistical significant difference in the level of pain and the need for analgesics between the wound irrigation and control groups.

  20. Pulsatile blood flow in Abdominal Aortic Aneurysms (United States)

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


    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.

  1. Prevention of peroperative hypothermia in abdominal surgery. (United States)

    Kristensen, G; Guldager, H; Gravesen, H


    It is important to reduce or prevent heat loss during anaesthesia, especially in patients with restricted cardiopulmonary reserves. To test a specially developed esophageal thermal tube (GK-esophageal thermal tube) for this purpose, 33 patients were randomly divided into two groups: Group A were given heat transferred to the central core during operation, using the GK-tube with circulating 41.7 degrees C warm water. Group B received no active warming. All patients were scheduled for major abdominal operation. In both groups there was a temperature fall in the induction phase. In Group B the temperature continued to fall slowly during operation, resulting in a median end-temperature of 34.9 degrees C. In Group A the temperature rose slowly after induction of heat via the tube, resulting in a median end-temperature of 36.8 degrees C in this actively warmed group. The temperature difference is significant (P less than 0.001). The median operating time was 3h 30 min in both groups. After 2 h of anaesthesia the median temperature in Group A was 36.1 degrees C and in Group B 35.0 degrees C. This difference is also significant (P less than 0.001). The described method was easy to use and without complications. We recommend this method to prevent peroperative hypothermia in all patients suspected to have limited cardiopulmonary reserves. The possible hazards and how to avoid these are described.

  2. Postpartum intra-abdominal haemorrhage: Case report

    Directory of Open Access Journals (Sweden)

    Tubić-Pavlović Aleksandra


    Full Text Available Introduction. The most frequent cause of gynaecological haemoperitoneum is ruptured ectopic pregnancy. Haemoperitoneum after a normal vaginal delivery is rare and it is associated with high maternal mortality. Case report. A 22-year-old primipara had a normal vaginal delivery. She experinced acute abdominal pain and hypovolemic shock ten hours after the delivery and was referred to our hospital twenty one hours after the delivery. An urgent ultrasound profile was done, which revealed free fluid in pelvis and in the whole abdomen. An immediate laparotomy was done and 2 litres of blood were found within the peritoneal cavity. The uterine wall was intact. We found a haematoma on the anterior wall of rectum and livid colours of broad ligament. The peritoneal cavity was cleaned and revised. Any injury of the spleen or liver was excluded. Discussion and conclusion. Haematoperitoneum after a normal vaginal delivery is rare but life threatening to mothers. It is important to recognize this condition to avoid delay in diagnosis and treatment because of high maternal mortality. Our patient was bleeding from superficial rectal vessels. Only a few cases with undefined aetiologies have been reported in literature.

    Full Text Available OBJETIVO: O papel da laparoscopia na redução da taxa de laparotomias não-terapêuticas e da morbidade em pacientes vítimas de trauma abdominal penetrante tem sido amplamente discutido durante os últimos anos. O objetivo do presente estudo é relatar a experiência inicial de um hospital universitário no manejo laparoscópico de pacientes com trauma abdominal penetrante. MÉTODO: Durante um período de três anos, a laparoscopia foi realizada em 37 pacientes vítimas de trauma abdominal penetrante, hemodinamicamente estáveis. Os prontuários médicos foram revisados e os parâmetros analisados foram as indicações do procedimento, lesões associadas, necessidade de conversão, tempo de permanência hospitalar e complicações. RESULTADOS: Houve 18 (48,6% casos de laparoscopias diagnósticas (LD positivas e 19 (51,4% negativas. Dos pacientes com LD positiva, oito (44,4% foram submetidos à laparotomia exploradora com finalidade terapêutica ou para melhor delineamento da lesão. Houve 10 (55,6% LD positivas nas quais não foi realizada conversão para cirurgia aberta. Quatro pacientes apresentaram lesões reparáveis laparoscopicamente, sendo realizado hepatorrafia (n=2 e frenorrafia (n=2. Os outros seis pacientes apresentavam lesões isoladas sem sangramento ativo, e a laparotomia não-terapêutica foi evitada. Os pacientes receberam dieta no primeiro dia de pós-operatório e o tempo médio de hospitalização foi de 3,8 dias. CONCLUSÕES: Nossa experiência inicial confirma que a laparoscopia é um bom método de avaliação e tratamento no trauma penetrante. A morbidade relacionada à laparotomias desnecessárias pode ser minimizada quando o procedimento é bem indicado, e o tratamento pode ser realizado com sucesso em casos selecionados.BACKGROUND: The role of laparoscopy in reducing the rate of non-therapeutic laparotomies and the morbidity in patients sustaining penetrating abdominal trauma has been widely discussed over the last

  5. [Abdominal pregnancy: hormon concentrations during the postpartal period with placenta remaining intra-abdominal (author's transl)]. (United States)

    Gethmann, U; Mönkemeier, D


    It is reported of an abdominal pregnancy at term. The placenta was left in situ because of the high risk of intraabdominal bleedings. Thereby it was possible to measure hormon concentrations of the fetoplacental unit without the fetal compartment. Within 10 days after delivery we determined the plasma levels of estradiol-17 beta, estriol, progesterone, HCS, alpha1fetoprotein, and the excretion of the total estrogens in the urines. There was near the same decrease of hormon concentrations in the post partal time comparable with that of a normal pregnancy. Only the HCS concentrations didn't change in the first 9 days after delivery.

    AIM: To analyze the local and systemic complications of high intensity focused ultrasound (HIFU) for patients with recurrent and metastatic abdominal tumors.METHODS: From Aug 2001 to Aug 2004, 17 patients with recurrent and metastatic abdominal tumors were enrolled in this study. Real-time sonography was taken, and vital signs, liver and kidney function, skin burns, local reactions, and systemic effects were observed and recored before, during, and after HIFU. CT and MRI were also taken before and after HIFU.RESULTS: All 17 patients had skin burns and pAln in the treatment region; the next common complication was neurapraxia of the stomach and intestines to variable degrees. The other local and systemic complications were relatively rare. Severe complications were present in two patients; one developed a superior mesenteric artery infarction resulting in necrosis of the entire small intestines, and the other one suffered from a perforation in terminal ileum due to HIFU treatment.CONCLUSION: Although HIFU is a one of noninvasive treatments for the recurrent and metastatic abdominal tumors, there are still some common and severe complications which need serious consideration.

    Leech, S.C.; Sullivan, P.B. [Dept. of Paediatrics, John Radcliffe Hospital, Oxford (United Kingdom); McHugh, K. [Department of Radiology, John Radcliffe Hospital, Oxford (United Kingdom)


    Background. Childhood constipation is common and assessment is often difficult. Plain abdominal radiography is simple and commonly used to assess constipation. The role of radiography with the use of a simple scoring system has not been fully evaluated. Objective. To assess the reliability of scoring faecal loading on plain abdominal radiographs in children with intractable constipation. Materials and methods. Plain abdominal radiographs from 33 constipated and 67 control children were independently assessed by three observers on two separate occasions. A scoring system was devised with scores from 0 (no stool) to 5 (gross faecal loading with bowel dilatation) in three areas of the colon, giving a total score of 0-15. Results. There were significant differences between the scores of the constipated and control radiographs for each observer (P = 0.05). There was no intra-observer variation (P = 0.12-0.69), but significant inter-observer variation was demonstrated (P = 0.00). Conclusions. We have found this scoring system to be a clinically useful and a reproducible tool in assessing childhood constipation. Assessment of faecal loading is subjective and varies between observers, although one observer will consistently score faecal loading on the same radiograph on successive occasions. To limit exposure to ionising radiation, we recommend that radiography be reserved for the investigation of intractable constipation, and its accuracy is improved if all radiographs are scored by the same observer.

  8. Ethnic differences in anthropometric measures and abdominal fat distribution

    DEFF Research Database (Denmark)

    Rønn, Pernille F.; Andersen, Gregers S.; Lauritzen, Torsten


    BACKGROUND: Ethnic variation in abdominal fat distribution may explain differences in cardiometabolic risk between populations. However, the ability of anthropometric measures to quantify abdominal fat is not clearly understood across ethnic groups. The aim of this study was to investigate...... the associations between anthropometric measures and visceral (VAT) and subcutaneous abdominal adipose tissue (SAT) in Inuit, Africans and Europeans. METHODS: We combined cross-sectional data from 3 studies conducted in Greenland, Kenya and Denmark using similar methodology. A total of 5275 individuals (3083 Inuit......, 1397 Africans and 795 Europeans) aged 17-95 years with measures of anthropometry and ultrasonography of abdominal fat were included in the study. Multiple regression models with fractional polynomials were used to analyse VAT and SAT as functions of body mass index (BMI), waist circumference, waist...

  9. Pylephlebitis: a rare complication of an intra-abdominal infection

    Directory of Open Access Journals (Sweden)

    Katherine Wong


    Full Text Available Pylephlebitis is defined as an inflamed thrombosis of the portal vein. It is a rare complication of an intra-abdominal infection, and the diagnosis is often missed due to its nonspecific clinical presentation. Symptoms may include abdominal pain, fever, chills, fatigue, nausea, and vomiting. It is important to consider this differential when a patient presents with signs of abdominal sepsis since it has a high mortality rate and is often diagnosed postmortem. Pylephlebitis can be diagnosed via abdominal ultrasound or CT demonstrating a thrombus in the portal vein, and it must be treated early and aggressively with broad-spectrum antibiotics. We are presenting a case of pylephlebitis as well as discussing the diagnosis and treatment of this potentially lethal condition.

  10. A case of lipoma of parietal peritoneum causing abdominal pain. (United States)

    Bang, Chang Seok; Kim, Yeon Soo; Baik, Gwang Ho; Han, Sang Hak


    Lipomas are common benign tumors of mature adipose tissue, enclosed by thin fibrous capsules. They can occur on any part of the body; however, peritoneal lipoma is extremely rare. We encountered a case of a 75-year-old man presenting with intermittent abdominal pain, who had undergone right hemicolectomy due to colon cancer. Abdominal computerized tomography showed a well-defined heterogenous fatty mass measuring 4.5 × 3.5 cm in size, suggesting fat necrosis located in the abdominal wall. Laparotomy showed a very large soft mass of peritoneum. Pathologically, the tumor was diagnosed as lipoma containing fat necrosis located in parietal peritoneum not fixed to any organs, but with small bowel adhesion. Due to its rare etiologic origin and obscure cause of development, we report on a case of lipoma of parietal peritoneum causing abdominal pain.

  11. Prosthetics and Techniques in Repair of Animal's Abdominal Wall. (United States)

    Karrouf, Gamal; Zaghloul, Adel; Abou-Alsaud, Mohamed; Barbour, Elie; Abouelnasr, Khaled


    The management of abdominal wall repair continues to present a challenging problem, especially in the repair of major defects. Many abdominal wall defects can be repaired by primary closure; however, if the defect is large and there is a tension on the closure of the wound, the use of prosthetic materials becomes indispensable. Many studies have been performed with various materials and implant techniques, without the comparison of their degrees of success, based on sound meta-analysis and/or inclusive epidemiologic studies. This review covered the effectiveness of recent advances in prosthetic materials and implant procedures used in repair of abdominal wall, based on biomechanical properties and economic aspects of reconstructed large abdominal wall defects and hernias in animals. The presented results in this review helped to reach treatment algorithms that could maximize outcomes and minimize morbidity.

  13. Torsion of a parasitic myoma that developed after abdominal myomectomy. (United States)

    Cho, In Ae; Baek, Jong Chul; Park, Ji Kwon; Song, Dae Hyun; Kim, Wan Ju; Lee, Yoon Kyoung; Park, Ji Eun; Shin, Jeong Kyu; Choi, Won Jun; Lee, Soon Ae; Lee, Jong Hak; Paik, Won Young


    Iatrogenic parasitic myomas are rare. The condition is defined by the presence of multiple smooth-muscle tumorous nodules in the peritoneal cavity. This may be attributable to seeding of myoma particles during uterine surgery. The clinical course is usually indolent. The disease is often asymptomatic and is usually discovered only incidentally. A 38-year-old woman who had undergone abdominal myomectomy 7 months prior presented with acute abdominal pain and a huge pelvic mass. We performed exploratory laparotomy. A parasitic mass 17 cm in diameter with a twisted omental pedicle was identified. En bloc excision of the mass and omentum was performed, followed by total abdominal hysterectomy. Histopathological examination of multiple sections revealed features compatible with an infarcted leiomyoma. Thus, we present a very rare case of an iatrogenic, rapidly growing parasitic myoma complicated by omental torsion (which caused the acute abdominal pain). We also offer a literature review.

  14. Functional abdominal pain causing Scurvy, Pellagra, and Hypovitaminosis A

  17. Ruptured abdominal aortic aneurysm and aortoiliac vein fistula. (United States)

    Gyoten, Takayuki; Doi, Toshio; Yamashita, Akio; Fukahara, Kazuaki; Kotoh, Keiju; Yoshimura, Naoki


    A 67-year-old man was admitted with severe abdominal pain and back pain. Computed tomography showed an infrarenal abdominal aortic aneurysm (8.4 × 8.3 cm) and a large retroperitoneal hematoma. Immediately afterwards, the patient suffered circulatory collapse and was rushed to the operating theater. A fistula communicating with the left iliac vein was found. It was repaired with a Dacron patch while balloon-tipped catheters controlled the bleeding. The abdominal aortic aneurysm was replaced with a bifurcated graft. The postoperative course was uneventful. There have been few reports of successful repair of a ruptured abdominal aortic aneurysm associated with aortoiliac arteriovenous fistula.

  18. Advancements in identifying biomechanical determinants for abdominal aortic aneurysm rupture. (United States)

    Kontopodis, Nikolaos; Metaxa, Eleni; Papaharilaou, Yannis; Tavlas, Emmanouil; Tsetis, Dimitrios; Ioannou, Christos


    Abdominal aortic aneurysms are a common health problem and currently the need for surgical intervention is determined based on maximum diameter and growth rate criteria. Since these universal variables often fail to predict accurately every abdominal aortic aneurysms evolution, there is a considerable effort in the literature for other markers to be identified towards individualized rupture risk estimations and growth rate predictions. To this effort, biomechanical tools have been extensively used since abdominal aortic aneurysm rupture is in fact a material failure of the diseased arterial wall to compensate the stress acting on it. The peak wall stress, the role of the unique geometry of every individual abdominal aortic aneurysm as well as the mechanical properties and the local strength of the degenerated aneurysmal wall, all confer to rupture risk. In this review article, the assessment of these variables through mechanical testing, advanced imaging and computational modeling is reviewed and the clinical perspective is discussed.

  20. Abdominal actinomycosis associated with intrauterine device: CT features. (United States)

    Laurent, T; de Grandi, P; Schnyder, P


    Abdominal actinomycosis is a severe and progressive peritoneal infection, due to an anerobic gram-positive bacterium, Actinomyces israelii. The presence of a long-standing intrauterine device (IUD) is a well-known risk factor in young women. We report two cases of pelviperitoneal actinomycosis appearing in two young women with acute low abdominal pain. Abdominal CT demonstrated multiple solid or encapsulated peritoneal masses with marked contrast enhancement and infiltration of the adjacent mesenteric fat. Laparoscopy confirmed the presence of intraperitoneal abscesses which contained Actinomyces israelii. High doses of amoxicillin and clavulanic acid (Augmentine) were given and following CT scan after 2 and 6 weeks showed a slow, but complete, resolution of the lesions. Although the radiologic presentation of actinomycosis is nonspecific, the diagnosis should be raised in the presence of pseudotumoral mesenteric infiltration, particularly in young women with an IUD. Abdominal CT is a useful method for diagnosis and for follow-up.

  1. Observation of a Flowing Duct in the Abdominal Wall by Using Nanoparticles. (United States)

    Jang, HyunSuk; Yoon, Joohwan; Gil, HyunJi; Jung, Sharon Jiyoon; Kim, Min-Suk; Lee, Jin-Kyu; Kim, Young-Jae; Soh, Kwang-Sup


    The primo vascular system (PVS) is being established as a circulatory system that corresponds to acupuncture meridians. There have been two critical questions in making the PVS accepted as a novel liquid flowing system. The first one was directly to show the flow of liquid in PVS and the second one was to explain why it was not observed in the conventional histological study of animal tissues. Flow in the PVS in the abdominal cavity was previously verified by injecting Alcian blue into a primo node. However, the tracing of the dye to other subsystems of the PVS has not been done. In the current work we injected fluorescent nanoparticles (FNPs) into a primo node and traced them along a primo vessel which was inside a fat tissue in the abdominal wall. Linea alba is a white middle line in the abdominal skin of a mammal and a band of fat tissue is located in parallel to the linea alba in the parietal side of the abdominal wall of a rat. In this fat band a primo vessel runs parallel to the prominent blood vessels in the fat band and is located just inside the parietal peritoneum. About the second question on the reason why the PVS was not in conventional histological study the current work provided the answer. Histological analysis with hematoxyline and eosine, Masson's trichrome, and Toluidine blue could not discriminate the primo vessel even when we knew the location of the PVS by the trace of the FNPs. This clearly explains why the PVS is hard to observe in conventional histology: it is not a matter of resolution but the contrast. The PVS has very similar structure to the connective tissues that surround the PVS. In the current work we propose a method to find the PVS: Observation of mast cell distribution with toluidine blue staining and the PN has a high density of mast cells, while the lymph node has low density.

  3. Massive ovarian oedema: an unusual abdominal mass in infancy. (United States)

    Moon, Rebecca J; Mears, Alice; Kitteringham, Lara J; Gonda, Peter; Kohler, Janice A; Davies, Justin H


    We describe a 13-month-old female who presented with vaginal bleeding, breast and pubic hair development and an abdominal mass. She underwent emergency laparotomy and left-sided salpingoophorectomy. Histological examination of the resected ovary revealed massive ovarian oedema, a rare non-neoplastic enlargement of the ovary. Consideration of this diagnosis in patients with an abdominal mass and endocrine disturbance may allow conservative surgery and preservation of fertility.

    Deniz Özçeker


    Full Text Available Hereditary angioedema (HA is a rare, autosomal-dominant genetic disorder presenting with recurrent attacks of angioedema. The most commonly involved organs include the extremites, face, neck, upper respiratory tract, genital region and the gastrointestinal tract. Edema of the intestinal mucosa can cause temporary obstruction and severe abdominal pain that can be confused with acute abdomen. Pediatricians and emergency physicians should keep in mind this rare disease in the differential diagnosis of severe abdominal pain.

    Full Text Available Extra-abdominal desmoid tumors are a significant cause of morbidity in patients with familial adenomatous polyposis syndrome. Understanding of the basic biology and natural history of these tumors has increased substantially over the past decade. Accordingly, medical and surgical management of desmoid tumors has also evolved. This paper analyzes recent evidence pertaining to the epidemiology, molecular biology, histopathology, screening, and treatment of extra-abdominal desmoid tumors associated with familial adenomatous polyposis syndrome.

  10. Abdominal candidiasis is a hidden reservoir of echinocandin resistance. (United States)

    Shields, Ryan K; Nguyen, M Hong; Press, Ellen G; Clancy, Cornelius J


    FKS mutant Candida isolates were recovered from 24% (6/25) of abdominal candidiasis patients exposed to echinocandin. Candida glabrata (29%) and Candida albicans (14%) mutants were identified. Multidrug-resistant bacteria were recovered from 83% of FKS mutant infections. Mutations were associated with prolonged echinocandin exposure (P = 0.01), breakthrough infections (P = 0.03), and therapeutic failures despite source control interventions (100%). Abdominal candidiasis is a hidden reservoir for the emergence of echinocandin-resistant Candida.

  14. Actinomycosis Presenting as an Abdominal Mass in a Child

    Directory of Open Access Journals (Sweden)

    Rahsan Özcan


    Full Text Available Abdominal actinomycosis in childhood period is very rare and a relation to trauma is not well established. Herein we report a case that appeared subsequent to abdominal trauma. A 17 years old boy presented with left lower quadrant abdominal mass and signs of acute abdomen. The symptoms of abdominal discomfort began after a fall from height 3 months before admission. There were signs of acute abdomen at physical examination. Ultrasound of abdomen demonstrated a mass; CT scan findings pointed to a suspicious “internal hernia”. An emergency laparotomy was performed. During surgery, a mass located over sigmoid colon and infiltrating the lateral abdominal wall was found. It was removed en bloc with the adjacent omentum. Except for the thickened sigmoid colon, no other pathologies were present at laparotomy. The pathology specimen revealed the actinomyces infection. The patient was treated with oral penicillin after discharge and the follow-up was uneventful. We advocate, keeping the actinomyces infection in mind in cases presenting with abdominal mass of unknown origin in childhood period.

  15. Ascariasis as a cause of recurrent abdominal pain. (United States)

    Guzman, Gerly Edson; Teves, Pedro Montes; Monge, Eduardo


    Ascariasis is the most common helminthic infection in developing countries. It may cause chronic abdominal pain, tenderness and bloating. Our aim is to report a case of acute episodic abdominal pain and pancreatitis associated with ascariasis. We report a 59-year-old female patient who was admitted for acute abdominal pain, having had several previous similar events before one of them was diagnosed as acute idiopathic pancreatitis. On admission, her physical exam was normal. Laboratory results showed hemoglobin 12.2 g/dL, white blood cell count 11 900 cells/mm(3), eosinophils 420 cells/mm(3), serum amylase 84 IU/mL, lipase 22 IU/mL and normal liver function tests. Abdominal ultrasound and a plain abdominal X-ray were also normal. An upper endoscopy showed round white worms in the duodenum and the stomach, some of them with bile in their intestines. The intestinal parasites were diagnosed as Ascaris lumbricoides, and the patient was started on albendazole, with full recovery within a week. We believe that ascariasis should be considered in patients with recurrent abdominal pain and idiopathic pancreatitis.

    TU Chang-di; WANG Shao-juan; ZHOU Ri-guang; WEI Yang-yi; TAN Qiang


    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.

The transversus abdominis plane (TAP) block is a recently described approach to providing analgesia to the anterior abdominal wall. We evaluated the analgesic efficacy of the TAP block in patients undergoing total abdominal hysterectomy via a transverse lower abdominal wall incision, in a randomized, controlled, double-blind clinical trial.

  19. Comparison of abdominal muscle thickness according to feedback method used during abdominal hollowing exercise. (United States)

    Lee, Sangyong; Han, Seulki; Lee, Daehee


    [Purpose] This study was intended to examine the most effective feedback method for contracting the musculus transversus abdominis muscle by using basic training, a pressure biofeedback unit, and real-time ultrasonographic imaging during abdominal hollowing exercise training. [Subjects and Methods] The subjects in this study were 30 healthy young students in their twenties. Thirty subjects were divided randomly and equally into the basic training, the pressure biofeedback unit, and real-time ultrasonographic imaging groups. All of the subjects received abdominal hollowing exercise training for 15 minutes. The subjects in the pressure biofeedback unit group were trained by using a pressure biofeedback unit. Those in the real-time ultrasonographic imaging group received training with monitoring of possible contraction of their musculus transversus abdominis muscles on ultrasonography. [Results] In all the three groups, the musculus transversus abdominis became significantly thicker, but more significantly in the real-time ultrasonographic imaging group than in the basic training group. [Conclusion] The feedback method using real-time ultrasonographic imaging may be more effective in thickening the musculus transversus abdominis muscle during exercise than the traditional feedback method with manual contact only. However, it is insufficient in terms of overall qualitative improvement of exercise outcome.

    阐述严重烧伤后围休克期并发腹腔间隙综合征(ACS)与全身炎症反应综合征(SIRS)的相关性.临床分析认为,SIRS是致ACS的主要原因之一,ACS是SIRS未及时有效控制和超量补液导致;另从循证医学角度论证ACS发生机制的新认识,认为"单纯补液过多导致ACS"的论断具有片面性;最后对严重烧伤后围休克期并发ACS的治疗提出了切实可行的思路及展望.%To explain the correlation between abdominal compartment syndrome ( ACS ) and systemic inflammatory response syndrome ( SIRS ) on perishock stage after severe burn. By clinical analysis, we hold that the ACS is secondary to SIRS when SIRS did not get timely and effective control or with excessive fluid infusion, and demonstrate the new mechanism of ACS from the point view evidence-based medicine. We believe " rehydration too much lead to ACS" is the one-sided view. Finally, prospect and practical idea are put forward to the treatment of ACS in patients with serious burn during peri-shock stage.

  1. Medical diagnosis aboard submarines. Use of a computer-based Bayesian method of analysis in an abdominal pain diagnostic program. (United States)

    Osborne, S F


    The medical issues that arise in the isolated environment of a submarine can occasionally be grave. While crewmembers are carefully screened for health problems, they are still susceptible to serious acute illness. Currently, the submarine medical department representative, the hospital corpsman, utilizes a history and physical examination, clinical acumen, and limited laboratory testing in diagnosis. The application of a Bayesian method of analysis to an abdominal pain diagnostic system utilizing an onboard microcomputer is described herein. Early results from sea trials show an appropriate diagnosis in eight of 10 cases of abdominal pain, but the program should still be viewed as an extended "laboratory test" until proved effective at sea.

  2. Management of Accidental Finding of Ascaris Lumbricoides During Emergent Abdominal Surgery: A Case Report and Review of the Literature. (United States)

    Esfehani, Maryam Hassan; Jahanshahi, Abdolhadi; Karimi, Amirhossein


    Ascariasis lumbricoides is the most common soil-transmitted helminth worldwide and most often is asymptomatic, although it can present with abdominal pain, malabsorption and growth failure, complete or partial obstraction in small bowel and biliary system and etc. Accidental encounters with ascaris during emergent abdominal surgeries are very rare and have been reported in less than a handful of papers. In this report, we describe this rare event from a country with low prevalence of this infection, and then review the literatures and clarify the possible challenges for surgeons during operation and postoperative follow-up.

    Vogel, H.; Belz, Buecheler, E.


    The number of transcatheteral occulsion of abdominal arteries reported so far enables us to differentiate between complications, which are specific for the methods used, or which are organ-specific and material-specific. Among the complications specific for the methods concerned are: complications occuring in angiography; tumour embolism in the lung; transport of embolic material into the lung; transport of embolic material into the arteries of the lower half of the body; renal insufficiency; necrosis; and, finally, abscess formation. Among the organ-specific complications are: necrosis (especially of the spleen and in the operated upper gastro-intestinal tract); abscess formation (spleen, kidneys, liver); retroperitoneal phlegmones (kidney); relapsing haemorrhages (gastro-intestinal tract, kidneys); renal insufficiency (in case of pre-existing renal damage); hypertension (described so far as transient blood pressure increase only); hypertensive crisis (after renal artery occulsion for malignant hypertension); hepatic insufficiency and gallbladder infarction (in embolisation of the liver); transport of embolic material into adjacent arteris (in case of embolisation, into the vessels of the truncus coeliacus); and, finally, hypoglycaemia (in embolisation of the liver). Among the material-specific complications are: adhesion of the catheter tip to the vascular wall (Bucrylate); dislocation of Gianturco's spiral; allergic (anaphylactic) reaction to the embolic material (not described so far); recanalisation (in case of absorbable substances such as Fibrospum and Gelfoam); substitutive blood supply via the formation or extension of collaterals; necrosis in peripherally (capillary) occluding substances such as Bucrylate and Ethibloc; and, finally, abscess formation (in case of non-sterile embolic material). Some of these complications can be classified under more than one category.

    Full Text Available Introduction. Kidney anomalies present a challenge even for the most experienced vascular surgeon in the reconstruction of the aortoilliac segment. The most significant anomalies described in the surgery of the aortoilliac segment are a horse-shoe and ectopic kidney. Objective. The aim of this retrospective study was to analyze experience on 40 patients with renal anomalies, who underwent surgery of the aortoilliac segment and to determine attitudes on conventional surgical treatment. Methods. In the period from 1992 to 2009, at the Clinic for Vascular Surgery of the Clinical Centre of Belgrade we operated on 40 patients with renal anomalies and aortic disease (aneurysmatic and obstructive. The retrospective analysis involved standard epidemiological data of each patient (gender, age, risk factors for atherosclerosis, type of anomaly, type of aortic disease, presurgical parameter values of renal function, type of surgical approach (laparatomy or retroperitoneal approach, classification of the renal isthmus, reimplantation of renal arteries and perioperative morbidity and mortality. Results. Twenty patients were males In 30 (70% patients we diagnosed a horse-shoe kidney and in 10 (30% ectopic kidney. In the cases of ruptured aneurysm of the abdominal aorta the diagnosis was made by ultrasound findings. Pre-surgically, renal anomalies were confirmed in all patients, except in those with a ruptured aneurysm who underwent urgent surgery. In all patients we applied medial laparatomy, except in those with a thoracoabdominal aneurysm type IV, when the retroperitonal approach was necessary. On average the patients were under follow-up for 6.2 years (from 6 months to 17 years. Conclusion. Under our conditions, the so-called double clamp technique with the preservation of the kidney gave best results in the patients with renal anomalies and aortic disease.

  5. The effect of abdominal resistance training and energy restricted diet on lateral abdominal muscles thickness of overweight and obese women. (United States)

    Noormohammadpour, Pardis; Kordi, Ramin; Dehghani, Saeed; Rostami, Mohsen


    The role of transabdominal muscles (external oblique, internal oblique and transversus abdominis) on core stability has been shown previously. Energy restricted diet and abdominal resistance training are commonly used by overweight and obese people to reduce their weight. In this study we investigated the impact of 12 weeks concurrent energy restricted diet and abdominal resistance training on the thickness of the lateral abdominal muscles of 19 obese and overweight women employing ultrasonography in resting and drawing-in maneuvers. The results showed significant increase of the muscle thicknesses during drawing-in maneuver after 12 weeks intervention. Based on our findings, it can be concluded that 12 weeks concurrent abdominal resistance training and energy restricted diet in addition to weight loss lead to improvement of transabdominal muscles thickness in obese and overweight people. Considering the role of these muscles in core stability, using this therapeutic protocol in obese people, particularly in those who have weakness of these muscles might be helpful.

  6. Abdominal computed tomography in macroglobulinemia (Waldenstroem's disease). Report of a case

    Energy Technology Data Exchange (ETDEWEB)

    Aspelin, P.; Adielsson, G.; Dimitrov, N.; Nyman, U.; Waldenstroem, J.

    The findings at abdominal computed tomography (CT) in a patient with primary macroglobulinemia (Waldenstroem's disease) are reported. CT was of special value in monitoring the extent of the disease in the abdomen and the response to treatment. At the first examination the patient had changes in both the reticuloendothelial system and the small bowel changes. The prompt disappearance on treatment of the small bowel changes proves that these changes were due to a high plasma viscosity syndrome. The slow response on the liver, spleen and lymph nodes suggests lymphomatous engagement. Although the primary method to diagnose Waldenstroem's disease is through laboratory tests, CT is of use in monitoring the abdominal involvement, especially the response to treatment.

  7. Tuberculous abdominal abscess in an HIV-infected man: Neither infection previously diagnosed

    Directory of Open Access Journals (Sweden)

    Kuo-Yao Kao


    Full Text Available A 38-year-old man had a 1-week history of right lower quadrant abdominal pain; the initial impression was that he had diverticulitis of the ascending colon with an intra-abdominal abscess. Signs of peritonitis mandated an immediate right hemicolectomy. The unusual location of the abscess and the patient’s unusual postoperative course suggested that he might also have a systemic disease. Testing for HIV infection was positive. After 2 weeks in hospital, he was treated as an outpatient for both tuberculosis and HIV with a favourable outcome. In Taiwan a pre-operative HIV test is not performed routinely, and the HIV seroprevalence in surgical patient populations is unknown. Surgeons should keep the possibility of HIV infection in mind in a patient with an unusual clinical course.

  8. Tai Chi Chuan modulates heart rate variability during abdominal breathing in elderly adults. (United States)

    Wei, Gao-Xia; Li, You-Fa; Yue, Xiao-Lin; Ma, Xiao; Chang, Yu-Kai; Yi, Long-Yan; Li, Jing-Cheng; Zuo, Xi-Nian


    Tai Chi Chuan (TCC) practice is currently intentionally applied in clinical populations, especially those with cardiovascular diseases because of its potential benefits on the autonomic nervous system. The long-term effect of TCC practice on heart rate variability (HRV) remains largely unknown. In this study, we recruited 23 TCC practitioners whose experience averaged approximately 21 years and 19 controls matched by age, sex and education to examine the effect of TCC practice on the autonomic nervous system during a resting state and during an abdominal breathing state. HRV was measured by traditional electrocardiogram (ECG) recording. The results showed that the low frequency, total power frequency, and normalized low frequency components and the low-frequency/high-frequency ratio were significantly higher, whereas the normalized high frequency was significantly lower in the TCC practitioners relative to controls during the abdominal breathing state. However, we did not detect any significant difference in the HRV measures during the resting state between the two groups. Additionally, TCC experience did not correlate with HRV components either in the abdominal state or the resting state in the TCC group. Considering all of these findings, we suggest that TCC improves vagal activity and the balance between sympathetic and parasympathetic activity during the relaxation state. This study also provides direct physiological evidence for the role of TCC practice in relaxation.

    Full Text Available Intra-abdominal infections are multifactorial and present an complex inflammatory response of the peritoneum to microorganisms followed by exudation in the abdominal cavity and systemic response Despite advances in management and critical care of patients with acute generalized peritonitis due to hollow viscus perforation, prognosis is still very poor, with high mortality rate. Early detection and adequate treatment is essential to minimize complications in the patient with acute abdomen. Prognostic evaluation of complicated IAI by modern scoring systems is important to assess the severity and the prognosis of the disease. Control of the septic source can be achieved either by nonoperative or operative means. Nonoperative interventional procedures include percutaneous drainages of abscesses. The management of primary peritonitis is non-surgical and antibiotic- treatment. The management of secondary peritonitis include surgery to control the source of infection, removal of toxins, bacteria, and necrotic tissue, antibiotic therapy, supportive therapy and nutrition. "Source control" is sine qua non of success and adequate surgical procedure involves closure or resection of any openings into the gastrointestinal tract, resection of inflamed tissue and drainage of all abdominal and pelivic collections.

  10. Analyzing intra-abdominal pressures and outcomes in patients undergoing emergency laparotomy

    Full Text Available Background : Studies have documented the impact of intra-abdominal hypertension (IAH on virtually every organ. However, it still remains strangely underdiagnosed. The aims of the study were to assess, in patients undergoing emergency laparotomy, whether intra-abdominal pressure (IAP is an independent predictor of morbidity and mortality, to evaluate the effects of IAH, and to identify hidden cases of abdominal compartment syndrome (ACS. Materials and Methods : The study comprised 197 patients undergoing emergency laparotomy. IAP was measured preoperatively and then postoperatively at 0, 6, and 24 hours. Duration of hospital stay, occurrence of burst abdomen, and mortality were noted as outcomes. Results : At admission, incidence of IAH was 80%. No significant association was found between IAP and occurrence of burst abdomen (P > 0.1. IAP was found to be a significant predictor of mortality in patients undergoing laparotomy (P < 0.001. Elevated IAP was found to affect all the organ systems adversely. The incidence of post-op ACS was 3.05% in the general population and 13.16% in trauma patients. The mortality rate for this subgroup was 100%. Conclusions : IAP is a significant predictor of mortality in patients undergoing laparotomy. IAH has detrimental effects on various organ systems. A more frequent monitoring with prompt decompression may be helpful in decreasing the mortality rate. Further studies are required to establish a screening protocol in patients undergoing laparotomy to detect and manage cases of IAH and ACS.

  11. Electromyographic investigation of abdominal exercises and the effects of fatigue. (United States)

    Robinson, Mark; Lees, Adrian; Barton, Gabor

    Abdominal exercises are widely used to develop the anterior muscles of the trunk. These exercises can be undertaken without the aid of equipment, but increasingly manufacturers are developing equipment which purportedly enhances the training effect for abdominal muscles. As there are many different products and exercises used for abdominal muscle development, it is likely that some are more effective than others. This study aimed to investigate the effectiveness of five commonly performed abdominal exercises. A second aim was to investigate the effects of fatigue on these exercises. Five different types of abdominal exercise [standard crunch (sit-up) with bent knees, gym ball crunch, crunch with 5 kg weight held behind the head, legs raised crunch and a commercially manufactured roller crunch] were examined using integrated surface electromyography (IEMG). The lower rectus abdominis (LRA), upper rectus abdominis (URA) and obliquus externus abdominis (EO) of 15 healthy male participants [age (mean +/- SD) 22.2 +/- 6.8 years; height 1.77 +/- 0.06 m; mass 79.3 +/- 10.7 kg] were monitored using a four-channel special purpose EMG data logger. Three trials of each exercise were performed in random order and normalized to enable comparisons between muscles and exercises. At a later date, ten participants were then re-tested when fresh and after a 30 min whole-body fatigue protocol that specifically targeted the abdominal muscles. Two exercises were evaluated, the abdominal roller crunch and legs raised crunch, which were judged to be the least and most effective, respectively, of the five exercises previously used. The normalized IEMG showed significant (p crunch = 86.0 +/- 7.5%; legs raised crunch = 79.9 +/- 5.1%; 5 kg weight crunch = 65.1 +/- 13.4%; standard crunch = 56.2 +/- 3.2%; and roller crunch = 45.0 +/- 11.4%). Post-fatigue, the normalized mean IEMG for both exercises increased significantly (p 0.05). It was concluded that exercises can be constructed to provide

    Introduction: Splenic and renal infarctions are usually related to vascular disease or haematologic abnormalities. Their association is infrequent and rarely observed in trauma. In this study, we analyze our data to look at the occurrence of renal and splenic infarctions based on CT findings in a period of 4 years. Materials and Methods: We retrospectively reviewed the imaging findings of 84 patients admitted to our Department of Diagnostic Imaging from June 1998 to December 2002, who underwent emergency abdominal spiral CT examination and in whom there was evidence of splenic and/or renal infarction. Results: We found 40 cases of splenic infarction and 54 cases of renal infarction, associated in 10 patients. In 26 patients, there was also evidence of intestinal infarction. A traumatic origin was found in 19 cases; non-traumatic causes were found in 65 patients. Association between renal and splenic infarction in the same patient was related to trauma in two cases. Conclusions: Although renal and splenic infarctions are a common manifestation of cardiac thromboembolism, other systemic pathologies, infections or trauma may lead to this occurrence. Renal infarction may be clinically and/or surgically managed with success in most cases. There are potential complications in splenic infarction, such as development of pseudocysts, abscesses, hemorrhage, subcapsular haematoma or splenic rupture; splenectomy in these cases may be necessary. Some patients with splenic and/or renal infarction may be clinically asymptomatic. The high accuracy of CT examination is needed to allow a correct evaluation of infarcted organs.

  13. Extra-abdominal venous thromboses at unusual sites. (United States)

    Martinelli, Ida; De Stefano, Valerio


    Venous thrombosis typically involves the lower extremities. Rarely, it can occur in cerebral, splanchnic, or renal veins, with a frightening clinical impact. Other rare manifestations are upper-extremity deep vein thrombosis, that can complicate with pulmonary embolism and post-thrombotic syndrome, and retinal vein occlusion, significantly affecting the quality of life. This review is focused on venous thromboses at unusual extra-abdominal sites. Local infections or cancer are frequent in cerebral sinus-venous thrombosis. Upper-extremity deep vein thrombosis is mostly due to catheters or effort-related factors. Common risk factors are inherited thrombophilia and oral contraceptive use. Acute treatment is based on heparin; in cerebral sinus-venous thrombosis, local or systemic fibrinolysis should be considered in case of clinical deterioration. Vitamin-K antagonists are recommended for 3-6 months; indefinite anticoagulation is suggested for recurrent thrombosis or unprovoked thrombosis and permanent risk factors. However, such recommendations mainly derive from observational studies; there are no data about long-term treatment of retinal vein occlusion.

  14. Abdominal thromboses of splanchnic, renal and ovarian veins. (United States)

    De Stefano, Valerio; Martinelli, Ida


    Thromboses of abdominal veins outside the iliac-caval axis are rare but clinically relevant. Early deaths after splanchnic vein thrombosis occur in 5-30% of cases. Sequelae can be liver failure or bowel infarction after splanchnic vein thrombosis, renal insufficiency after renal vein thrombosis, ovarian infarction after ovarian vein thrombosis. Local cancer or infections are rare in Budd-Chiari syndrome, and common for other sites. Inherited thrombophilia is detected in 30-50% of patients. Myeloproliferative neoplasms are the main cause of splanchnic vein thrombosis: 20-50% of patients have an overt myeloproliferative neoplasm and/or carry the molecular marker JAK2 V617F. Renal vein thrombosis is closely related to nephrotic syndrome; finally, ovarian vein thrombosis can complicate puerperium. Heparin is used for acute treatment, sometimes in conjunction with systemic or local thrombolysis. Vitamin K-antagonists are recommended for 3-6 months, and long-term in patients with Budd-Chiari syndrome, unprovoked splanchnic vein thrombosis, or renal vein thrombosis with a permanent prothrombotic state such as nephrotic syndrome.

  16. Abdominal wall repair with human acellular dermal autograft

    Directory of Open Access Journals (Sweden)

    Roel E. Genders


    Full Text Available Repair of abdominal wall defects in the presence of contamination or infection is a significant problem. The loss of tissue warrants enforcement of the abdominal wall, preferably by autologous material. However, autologous repair often requires extensive surgery. This paper presents a review of available literature of placement of an acellular human dermis to repair an abdominal fascia defect, in contaminated as well as in non-contaminated surgical fields. It is illustrated with a case report that describes the successful reconstruction of an infected abdominal wall defect with a human acellular dermis allograft. A systematic literature review was undertaken with searches performed in the Pubmed and Cochrane databases for the period up till March 2009, using the search terms Alloderm [Substance Name], Hernia [Mesh] and the key words acellular dermis, acellular dermal matrix, human acellular dermal allograft and abdominal wall defect. To assess methodological quality, each article was subjected to a modification of the methodological index for non-randomized studies (MINORS according to Slim et al. Two items from the original index were not included because none of the studies selected had an unbiased assessment of the study end points and in none of the studies was a prospective calculation of the study size performed. Seventeen studies were included in the review. Data were extracted regarding study design, number of patients, surgical technique, followup period, contaminated or non-contaminated area of the fascia defect, mortality and morbidity (hemorrhage, seroma, wound dehiscence, infection of the operative procedure, the longterm results (removal of the graft, reherniation and bulging and level of evidencey. A total of 169 short-term complications and 151 longterm complications occurred after 643 surgical procedures reconstructing both contaminated and clean abdominal wall defects by implantation of an HADA.

    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.

  18. Does computer-aided clinical decision support improve the management of acute abdominal pain? A systematic review. (United States)

    Cooper, Jamie G; West, Robert M; Clamp, Susan E; Hassan, Tajek B


    Acute abdominal pain is a common reason for emergency presentation to hospital. Despite recent medical advances in diagnostics, overall clinical decision-making in the assessment of patients with undifferentiated acute abdominal pain remains poor, with initial clinical diagnostic accuracy being 45-50%. Computer-aided decision support (CADS) systems were widely tested in this arena during the 1970s and 1980s with results that were generally favourable. Inception into routine clinical practice was hampered largely by the size and speed of the hardware. Computer systems and literacy are now vastly superior and the potential benefit of CADS deserves investigation. An extensive literature search was undertaken to find articles that directly compared the clinical diagnostic accuracy prospectively of medical staff in the diagnosis of acute abdominal pain before and after the institution of a CADS programme. Included articles underwent meta-analysis with a random-effects model. Ten studies underwent meta-analysis that demonstrated an overall mean percentage improvement in clinical diagnostic accuracy of 17.25% with the use of CADS systems. There is a role for CADS in the initial evaluation of acute abdominal pain, which very often takes place in the emergency department setting.

    Full Text Available Objective. To describe a profoundly immunocompromised (panleukopenia child with septic shock who developed abdominal compartment syndrome (ACS and was successfully treated with surgical decompression. Design. Individual case report. Setting. Pediatric intensive care unit of a tertiary children's hospital. Patient. A 32-month-old male with Fanconi anemia who underwent bone marrow transplantation (BMT 5 days prior to developing septic shock secondary to Streptococcus viridans and Escherichia coli ACS developed after massive fluid resuscitation, leading to cardiopulmonary instability. Interventions. Emergent surgical bedside laparotomy and silo placement. Measurements and Main Results. The patient's cardiopulmonary status stabilized after decompressive laparotomy. The abdomen was closed and the patient survived to hospital discharge without cardiac, respiratory, or renal dysfunction. Conclusions. The use of laparotomy and silo placement in an unengrafted BMT patient with ACS and septic shock did not result in additional complications. Surgical intervention for ACS is a reasonable option for high risk, profoundly immunocompromised patients.

  1. Aneurisma de aorta abdominal na infância Abdominal aortic aneurism in childhood

    Directory of Open Access Journals (Sweden)

    Abdo Farret Neto


    Full Text Available The authors report a case of an abdominal aortic aneurism involving all visceral branches minus the Inferior Mesenteric artery in a 4-year-old girl. There was sugestive evidence that the arterial disease had an inflamatory or infectious etiologic factor. The most probable etiological factors could be salmonelas infection of the arterial wall or Takayasu's disease secondary to tuberculosis. The treatment with antibiotic to salmonelas infection during ten days, followed by tuberculostatic therapy for six months was chosen. Concerning the age, the arteries involved and the inflamatory aspect of the aneurysm, the surgical option became an alternative to the clinic treatment in case of any future evidence of the aneurysm enlargement. The patient became asymptomatic as soon as the antibiotic has been started. The control of the aneurysm evolution will be made by ecography each three months.

  2. Morphological description of collateral branches from the abdominal aorta of lesser anteater (Tamandua tetradactyla

    Directory of Open Access Journals (Sweden)

    Breno Costa Macedo


    Full Text Available Tamandua tetradactyla, Xenarthra, is a native species from South America which, due to the few number of studies on its biology, still has many unknown aspects in its morphology. Taking into account the importance of morphological data for various studies, this paper aimed to elucidate the branching of the abdominal aorta in this species to foster the development of further studies. To do this, 4 specimens were used, 2 male and 2 female, all young, from the Bauxite Mine – Paragominas, Para, Brazil, donated after death due to running over to the Animal Morphology Research Laboratory (LaPMA of Universidade Federal Rural da Amazonia (UFRA. The arterial system was filled with contrasted latex and the animals were fixed in a formaldehyde solution (10%, and then dissected, in order to evidence the abdominal aorta and its collateral branches. The parietal branches consisted of 1 pair of caudal phrenic arteries, 2 pairs of intercostal arteries, and 3 pairs of lumbar arteries. Among the visceral branches, stood out: celiac artery; cranial mesenteric artery; adrenal arteries; renal arteries; caudal mesenteric artery; and external, internal, and median sacral iliac arteries, formed from the final portion of the abdominal aorta. Testicular and ovarian arteries originated from the renal arteries, differing from that described in various species.

  3. Thoracic paravertebral blocks in abdominal surgery - a systematic review of randomized controlled trials. (United States)

    El-Boghdadly, K; Madjdpour, C; Chin, K J


    Thoracic paravertebral blocks (TPVBs) have an extensive evidence base as part of a multimodal analgesic strategy for thoracic and breast surgery and have gained popularity with the advent of ultrasound guidance. However, this role is poorly defined in the context of abdominal surgery. We performed a systematic review of randomized controlled trials, to clarify the impact of TPVB on perioperative analgesic outcomes in adult abdominal surgery. We identified 20 published trials involving a total of 1044 patients that met inclusion criteria; however there was significant heterogeneity in terms of type of surgery, TPVB technique, comparator groups and study quality. Pain scores and opioid requirements in the early postoperative period were generally improved when compared with systemic analgesia, but there was insufficient evidence for any definitive conclusions regarding comparison with epidural analgesia or other peripheral block techniques, or the benefit of continuous TPVB techniques. The reported primary block failure rate was 2.8% and the incidence of complications was 1.2% (6/504); there were no instances of pneumothorax. TPVB therefore appears to be a promising analgesic technique for abdominal surgery in terms of efficacy and safety. But further well-designed and adequately powered studies are needed to confirm its utility, particularly with respect to other regional anaesthesia techniques.

    AIM: To assess the value of widely used clinical scores in the early identification of acute pancreatitis (AP) patients who are likely to suffer from intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS). METHODS: Patients ( n = 44) with AP recruited in this study were divided into two groups (ACS and non-ACS) according to intra-abdominal pressure (IAP) determined by indirect measurement using the transvesical route via Foley bladder catheter. On admission and at regular intervals, the severity of the AP and presence of organ dysfunction were assessed utilizing different multifactorial prognostic systems: Glasgow-Imrie score, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE-Ⅱ) score, and Multiorgan Dysfunction Score (MODS). The diagnostic performance of scores predicting ACS development, cut-off values and specificity and sensitivity were established using receiver operating characteristic (ROC) curve analysis. RESULTS: The incidence of ACS in our study population was 19.35%. IAP at admission in the ACS group was 22.0 (18.5-25.0) mmHg and 9.25 (3.0-12.4) mmHg in the non-ACS group ( P 7; MODS > 2 or Glasgow-Imrie score > 3).

  5. [Hematoma of the abdominal wall. A case report: pitfall of Seldinger method via femoral artery]. (United States)

    Hiramatsu, Hisaya; Sugiura, Yasushi; Takeda, Ririko; Nanba, Hiroki


    We reported a case of an abdominal wall hematoma which caused by Seldinger method via the femoral artery. A 48-year-old female, suffered from direct carotid cavernous fistula, was treated by transfemoral transvenous embolization (TVE). The whole procedure was completed without difficulty except minor resistance of guide wire manipulation during left femoral artery catheterization. Four hours later, the patient became hypotensive and showed the sign of impending shock without definitive causes. Nine hours after the embolization a huge hematoma of the abdominal wall was found. It required the total 1200 m/ of blood transfusion before her blood pressure returned to normal. She recovered fully from this event and discharged uneventfully. There is a speculation that a deep circumflex iliac artery (DCIA) was injured with an angle-shaped guide wire and bled into the abdominal wall. And subsequent systemic heparinization prevented the coagulation process, resulting a large hematoma. Anatomically, an angle-shaped guide wire is easily able to migrate into DCIA. To prevent a vascular injury, it is very important to manipulate a guide wire under fluoroscopic control and to select a J-shaped guide wire instead of an angle-shaped one.

    [Purpose] The purpose of the present study was to verify a new method for improving respiratory functions by applying both abdominal stimulation and inspiratory muscle training (IMT) to train the inspiratory muscle and the expiratory muscle simultaneously, to improve the efficiency of IMT of chronic stroke patients. [Subjects] Eighteen stroke patients were randomly assigned to an experimental group (n = 9) and a control group (n = 9). [Methods] The experimental group was administered IMT with abdominal stimulation, and the control group was administered only IMT. During the intervention period, the experimental group and control group received training 20 min/day, 3 times/wk, for 4 weeks. To examine the lung functions of the subjects, FVC, FEV1, PEF, and FEF25-75 were measured using an electronic spirometer. The diaphragm thickness ratio was calculated from measurements made with a 7.5-MHz linear probe ultrasonic imaging system. [Result] The experimental group and the control group showed significant increases in diaphragm thickness ratio on the paretic side, but not on the non-paretic side. With regard to lung function, the experimental group showed significant increases in FEV1, PEF, and FEF25-75. The changes between before and after the intervention in the two groups were compared with each other, and the results showed significant differences in FEV1 and PEF. [Conclusion] The present study identified that IMT accompanied by abdominal stimulation improved the pulmonary function of chronic stroke patients.

    Introduction: paracoccidioidomycosis (PCM) is a polymorphic systemic granulomatous inflammatory disease determined by Paracoccidioides brasiliensis, one of the 10 leading causes of morbidity and mortality among the parasitic diseases endemic in Brazil. Objective: To identify the following aspects of PCM by ultrasound (US) and computed tomography (CT): abdominal changes, intensity and characteristics of the observed images, frequency of changes depending on clinical presentation, differences from other nosological entities. Patients and methods: This was a retrospective, observational, cross-sectional study carried out with 35 patients with PCM treated at the Hospital das Clinicas (HC) at the Universidade Federal de Minas Gerais (UFMG). Patients with tuberculosis, bronchial asthma, generalized chronic obstructive pulmonary disease, or in contact with silica or mines, as well as those with granulomatous diseases at any point in their current or past clinical history and detected through serology, anatomopathology or microbiological exams were excluded. Collected data were transcribed into SPSS for Windows® for statistical analysis. The study was approved by the UFMG Ethics Committee (082/00). Results and conclusion: CT and U.S. showed involvement of abdominal organs in all forms of PCM, including lymphadenopathy (40%), hepatomegaly (37%), splenomegaly (37%) and adrenal involvement (17%). Gallbladder and retroperitoneal musculature involvement were also observed, along with ascites and pleural effusion. Lymph node calcification, adrenal involvement and ascites constituted evidence of high probability of PCM even though these findings are not enough to differentiate PCM from tuberculosis. Chronic and sequelae forms, abdominal involvement is more frequent than indicated by the clinical manifestations. (author)

  8. Contrast-enhanced MR angiography of abdominal vessels: Is there still a role for angiography?

    Vosshenrich, R.; Fischer, U. [Department of Radiology, Georg-August-Universitaet Goettingen (Germany)


    The purpose of this review article is to describe recent advantages in contrast-enhanced (CE) three-dimensional (3D) magnetic resonance angiography (MRA) in comparison with other vascular imaging techniques, and to discuss their current clinical applications for the imaging of abdominal vessels. Principles and technical considerations are presented and clinical applications are reviewed for different vascular diseases. In ruptured aortic aneurysms and acute dissections CT is the method of first choice. Contrast-enhanced 3D MRA can be well used for therapeutic planning and follow-up in patients with stable disease. A comprehensive MR examination including CE 3D MRA, MR urography and MR nephrogram has the potential to replace the conventional studies for the evaluation of renal vascular disease. It is an accurate method for imaging the origins of coeliac and superior mesenteric arteries, although the image resolution is too low for reliable assessment of the inferior mesenteric artery. Contrast-enhanced 3D MRA has emerged as the method of choice for studying the portal venous system in liver transplant recipients, in patients with portal hypertension and in cases with abdominal tumours for preoperative evaluation. Additional non-invasive flow measurements are useful in monitoring portal hypertension. The abdominal veins can be well imaged using unenhanced MR techniques. Imaging may be facilitated with intravascular contrast media. Contrast-enhanced 3D MRA can replace intra-arterial DSA for diagnosis, therapy planning and follow-up in patients with abdominal vascular disease. Catheter-based arteriography will still be used for interventional procedures such as percutaneous transluminal angioplasty, stent placement and embolisation. (orig.)

  9. Influence of exercise training on the oxidative capacity of rat abdominal muscles (United States)

    Uribe, J. M.; Stump, C. S.; Tipton, C. M.; Fregosi, R. F.


    Our purpose was to determine if endurance exercise training would increase the oxidative capacity of the abdominal expiratory muscles of the rat. Accordingly, 9 male rats were subjected to an endurance training protocol (1 h/day, 6 days/week, 9 weeks) and 9 litter-mates served as controls. Citrate synthase (CS) activity was used as an index of oxidative capacity, and was determined in the following muscles: soleus, plantaris, costal diaphragm, crural diaphragm, and in all four abdominal muscles: rectus abdominis, transversus abdominis, external oblique, and internal oblique. Compared to their non-trained litter-mates, the trained rats had higher peak whole body oxygen consumption rates (+ 16%) and CS activities in plantaris (+34%) and soleus (+36%) muscles. Thus, the training program caused substantial systemic and locomotor muscle adaptations. The CS activity of costal diaphragm was 20% greater in the trained animals, but no difference was observed in crural diaphragm. The CS activity in the abdominal muscles was less than one-half of that in locomotor and diaphragm muscles, and there were no significant changes with training except in the rectus abdominis where a 26% increase was observed. The increase in rectus abdominis CS activity may reflect its role in postural support and/or locomotion, as none of the primary expiratory pumping muscles adapted to the training protocol. The relatively low levels of CS activity in the abdominal muscles suggests that they are not recruited frequently at rest, and the lack of an increase with training indicates that these muscles do not contribute significantly to the increased ventilatory activity accompanying exercise in the rat.

    Costa, Sílvia; Gomes, Aline; Graça, Susana; Ferreira, António; Fernandes, Gonçalo; Esteves, Joana; Costa, Alexandre; Fernandes, Paula; Castelões, Paula; Maciel, Jorge


    The Abdominal Compartment Syndrome (ACS) is a clinical entity recognized for over a century, but only recently its risk criteria, monitorization and treatment have been defined by the World Society of the Abdominal Compartment Syndrome (WSACS). The general surgeon's involvement is vital since this syndrome is common in surgical patients and because its treatment may culminate in a laparostomy. 250 questionnaires of 17 questions were distributed among general surgeons attending the XXVIII Portuguese Congress of Surgery. The data were analyzed using SPSS® v16. We received 36,4% (91) of the delivered questionnaires, most of which from male surgeons (63,7%), from central hospitals (75,8%), working 42 h per week (70.3%), whose average of age was 38 years. About half of the respondents received training in Intensive Care Units. All surgeons had already heard about measuring the Intra- abdominal Pressure (IAP), which was being performed at 89% of their hospitals. About 40% of surgeons only admitted intra-abdominal hypertension above 20 mmHg (only 22% indicated the correct value of 12 mmHg). 36,3% of surgeons suggested that a decompressive laparostomy must be carried out for primary ACS if IAP greater then 20 mmHg with new organ failure; 36.3% favoured the "Vacuum-pack"-like system, and 56% only re-operate the patients "as needed". 48,4% of surgeons had already performed decompressive laparostomy, 66% of which had residence training in a ICU (p = 0,005). Respondents also pointed an average mortality related to ACS of 81% without laparostomy, and a reduction to 38,5% after performing that procedure. Only 26% of the surgeons were aware of the WSACS consensus definitions and recommendations, of those, 83% had already performed a laparostomy (Pdivulgation.

    Full Text Available Abstract Introduction Traumatic hernia of the abdominal wall is a rare entity. A large proportion of reported cases are in children with a particular type of injury, i.e. from a handlebar injury. In adults, the presentation can vary substantially and the diagnosis is difficult. We present two cases in adults, with widely varying presentations and management. Case presentations A 40-year-old woman from rural north India presented with a low-velocity blunt injury to the lower abdomen. She was attacked by a bull. She had a clinically evident abdominal fascial disruption with intact skin, and was hemodynamically stable. An emergency mesh repair of the defect was performed, and she recovered well. A 38-year-old man from rural north India presented with blunt trauma to the abdomen following a motor vehicle accident. He was stable, with a central abdominal parietal wall swelling and bruising. A computed tomography scan revealed herniation of bowel loops in the area with minor intra-abdominal injuries. A laparotomy, resection-anastomosis of the ischemic bowel, and primary repair of the defect was performed and he recovered well. Conclusion Following blunt abdominal trauma, particularly high-velocity injuries, a high index of suspicion must be reserved for parietal wall swellings, as missed hernias in this setting have a high risk of strangulation. Computed tomography is the best aid to diagnosis. Management of each case needs to be individualized.

  12. Open abdomen management of intra-abdominal sepsis. (United States)

    Adkins, Amy L; Robbins, James; Villalba, Mario; Bendick, Phillip; Shanley, Charles J


    Despite surgical advances, antimicrobial therapy, and intensive care, the morbidity and mortality of intra-abdominal sepsis remains high. The primary purpose of this study was to determine whether open abdomen management of intra-abdominal sepsis reduces intensive care unit (ICU) and hospital mortality. The records of 81 consecutive patients with open abdomen management for intra-abdominal sepsis admitted to the surgical ICU from January 1998 to April 2002 were retrospectively reviewed. Outcomes were compared to a historical control group with primary abdominal closure, also admitted to the surgical ICU with intra-abdominal sepsis and matched for sex, age, source of sepsis, and APACHE III score. ICU mortality for the open abdomen group was 25 per cent versus 17 per cent for the control group. Hospital mortality was 33 per cent and 25 per cent for the open abdomen patients and historical controls, respectively. Both ICU and hospital length of stay were significantly longer for the open abdomen group. An overall fistula rate of 14.8 per cent was demonstrated in the open abdomen patients. A significant difference in overall ICU and hospital mortality was not demonstrated between patients treated with open abdomen management and historical controls. A prospective randomized study accounting for extent of sepsis may define a role for open abdomen management in selected subgroups of patients.

    Full Text Available Abstract Purpose Appendicitis is the most common abdominal inflammatory process in children which were sometimes followed by complications including intra-abdominal abscess. This later needs classically a surgical drainage. We evaluated the efficacy of antibiotic treatment and surgical drainage. Methods Hospital records of children treated in our unit for intra-abdominal post appendectomy abscesses over a 6 years period were reviewed retrospectively. Results This study investigates a series of 14 children from 2 to 13 years of age with one or many abscesses after appendectomy, treated between 2002 and 2007. Seven underwent surgery and the others were treated with triple antibiotherapy. The two groups were comparable. For the 7 patients who receive medical treatment alone, it was considered efficient in 6 cases (85% with clinical, biological and radiological recovery of the abscess. There was one failure (14%. The duration of hospitalization from the day of diagnosis of intra-abdominal abscess was approximately 10.28 days (range 7 to 14 days. In the other group, the efficacy of treatment was considered satisfactory in all cases. The duration of hospitalization was about 13 days (range: 9 to 20. Conclusion Compared to surgical drainage, antibiotic management of intra-abdominal abscesses was a no invasive treatment with shorter hospitalization.

  14. Supraspinal TRPV1 modulates the emotional expression of abdominal pain. (United States)

    Jurik, Angela; Ressle, Andrea; Schmid, Roland M; Wotjak, Carsten T; Thoeringer, Christoph K


    The transient receptor potential vanilloid receptor type-1 (TRPV1) is critically involved in peripheral nociceptive processes of somatic and visceral pain. However, the role of the capsaicin receptor in the brain regarding visceral pain remains elusive. Here, we studied the contribution of TRPV1 to abdominal pain transmission at different nociceptive pathway levels using TRPV1 knock-out mice, resiniferatoxin-mediated deletion of TRPV1-positive primary sensory neurons, and intracerebral TRPV1 antagonism. We found that constitutive genetic TRPV1 deletion or peripheral TRPV1 deletion reduced acetic acid-evoked abdominal constrictions, without affecting referred abdominal hyperalgesia or allodynia in an acute pancreatitis model of visceral pain. Notably, intracerebral TRPV1 antagonism by SB 366791 significantly reduced chemical and inflammatory spontaneous abdominal nocifensive responses, as observed by reduced expressions of nociceptive facial grimacing, illustrating the affective component of pain. In addition to the established role of cerebral TRPV1 in anxiety, fear, or emotional stress, we demonstrate here for the first time that TRPV1 in the brain modulates visceral nociception by interfering with the affective component of abdominal pain.

  15. Synthetic, biological and composite scaffolds for abdominal wall reconstruction. (United States)

    Meintjes, Jennifer; Yan, Sheng; Zhou, Lin; Zheng, Shusen; Zheng, Minghao


    The reconstruction of abdominal wall defects remains a huge surgical challenge. Tension-free repair is proven to be superior to suture repair in abdominal wall reconstruction. Scaffolds are essential for tension-free repair. They are used to bridge a defect or reinforce the abdominal wall. A huge variety of scaffolds are now commercially available. Most of the synthetic scaffolds are composed of polypropylene. They provide strong tissue reinforcement, but cause a foreign body reaction, which can result in serious complications. Absorbable synthetic scaffolds, such as Dexon™ (polyglycolic acid) and Vicryl™ (polyglactin 910), are not suitable for abdominal wall reconstruction as they usually require subsequent surgeries to repair recurrent hernias. Composite scaffolds combine the strength of nonabsorbable synthetic scaffolds with the antiadhesive properties of the absorbable scaffold, but require long-term follow-up. Biological scaffolds, such as Permacol™, Surgisis(®) and Alloderm(®), are derived from acellular mammalian tissues. Non-cross-linked biological scaffolds show excellent biocompatibility and degrade slowly over time. However, remnant DNA has been found in several products and the degradation leads to recurrence. Randomized controlled trials with long-term follow-up studies are lacking for all of the available scaffolds, particularly those derived from animal tissue. This article provides an overview of the different types of scaffolds available, and presents the key clinical studies of the commercially available synthetic, composite and biological scaffolds for abdominal wall reconstruction.

    compared with the third group, moreover the indicated decline was more pronounced in men of the 1st group. The content of SHBG in serum was also significantly lower in the 1st and 2nd groups in relation to the 3rd group. Comparison of ejaculate indicators revealed significant differences in the 1st and 2nd groups of men, differing in the type of fat distribution, in terms of volume of ejaculate, share of progressively motile sperm and DNA fragmentation level. Differences are identified for some indicators of ejaculate between the 1st and 3rd groups, but the differences between the 2nd and 3rd groups on any indicator are not detected. Conclusion. The revealed differences indicate a negative effect on the ejaculate indicators, particularly of upper type of fat distribution, peculiar to the men of the 1st group. The obtained results justify the assumption that abdominal obesity with upper type fat distribution is an independent risk factor of male fertility reduction.

    OBJECTIVE: To reach an evidence-based consensus on the relative merits of vertical and transverse laparotomy incisions. DESIGN: Review of all published randomised controlled trials that compared the postoperative complications after the two main types of abdominal incisions, vertical and transverse......, and late complications (incisional hernia). RESULTS: Eleven randomised controlled trials and seven retrospective studies were identified. The transverse incision offers as good an access to most intra-abdominal structures as a vertical incision. The transverse incision results in significantly less.......0001), and regarding late incisional hernia the pooled odds ratio was 1.68 (95% confidence interval 1.10 to 2.57. p = 0.02). CONCLUSIONS: Transverse incisions in abdominal surgery are based on better anatomical and physiological principles. They should be recommended, as the early postoperative period is associated...

    López-Cano, Manuel; Pereira, José Antonio; Villanueva, Borja; Vallribera, Francesc; Espin, Eloy; Armengol Carrasco, Manuel; Arbós Vía, María Antonia; Feliu, Xavier; Morales-Conde, Salvador


    The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site. The management of the abdominal wall has different areas that should be analyzed such us how to avoid surgical site infection (SSI), the technique to be used in case of a concomitant hernia at the stoma site or to prevent an incisional hernia in the future, how to deal with the incision when the stoma reversal procedure is performed by laparoscopy and how to close the skin at the stoma site. The aim of this paper is to analyze these aspects in relation to abdominal wall reconstruction during a stoma reversal procedure.

  20. [Mediastino-abdominal lipomatosis. Description of a case]. (United States)

    Potestà, D; Mecenate, F


    The authors describe a case of mediastino-abdominal lipomatosis. The patient, who is 70 years old, was kept under observation, because of her recent state of illness. This state of illness was initially interpreted as angor attacks and a left ventricular failure. Only after the results of a CT examination showing a characteristic disproportion between the endothoracic-endoabdominal adipose tissue and the subcutaneous tissue, a correct interpretation was given. As a result the patient's state of illness was attributed to a compression of the adipose tissue growth in the abdominal and thoracic cavity. The etiology of mediastino-abdominal lipomatosis is still unknown. Therapy consists in removing the lipomas surgically when they cause a compression of the trachea and the upper vena cava.
