    Full Text Available 550 cases of acute abdomen have been analysed in detail includ-ing their clinical presentation and operative findings. Males are more frequently affected than females in a ratio of 3: 1. More than 45% of patients presented after 48 hours of onset of symptoms. Intestinal obstruction was the commonest cause of acute abdomen (47.6%. External hernia was responsible for 26% of cases of intestinal obstruction. Perforated peptic ulcer was the commonest cause of peritonitis in the present series (31.7% while incidence of biliary peritonitis was only 2.4%.. The clinical accuracy rate was 87%. The mortality in operated cases was high (10% while the over-all mortality rate was 7.5%.

    Acute abdomen can be defined as a medical emergency in which there is sudden and severe pain in abdomen with accompanying signs and symptoms that focus on an abdominal involvement. It accounts for about 8 % of all children attending the emergency department. The goal of emergency management is to identify and treat any life-threatening medical or surgical disease condition and relief from pain. In mild cases often the cause is gastritis or gastroenteritis, colic, constipation, pharyngo-tonsilitis, viral syndromes or acute febrile illnesses. The common surgical causes are malrotation and Volvulus (in early infancy), intussusception, acute appendicitis, and typhoid and ischemic enteritis with perforation. Lower lobe pneumonia, diabetic ketoacidosis and acute porphyria should be considered in patients with moderate-severe pain with little localizing findings in abdomen. The approach to management in ED should include, in order of priority, a rapid cardiopulmonary assessment to ensure hemodynamic stability, focused history and examination, surgical consult and radiologic examination to exclude life threatening surgical conditions, pain relief and specific diagnosis. In a sick patient the initial steps include rapid IV access and normal saline 20 ml/kg (in the presence of shock/hypovolemia), adequate analgesia, nothing per oral/IV fluids, Ryle's tube aspiration and surgical consultation. An ultrasound abdomen is the first investigation in almost all cases with moderate and severe pain with localizing abdominal findings. In patients with significant abdominal trauma or features of pancreatitis, a Contrast enhanced computerized tomography (CECT) abdomen will be a better initial modality. Continuous monitoring and repeated physical examinations should be done in all cases. Specific management varies according to the specific etiology.

    Full Text Available Objective: To evaluate the etiology, clinical profile and outcome of acute abdomen presentation in Dengue Fever (DF. Methods: This clinical prospective study was done on confirmed cases of DF admitted in the department of medicine during recent epidemic (September 2015 to November 2016. All patients were evaluated clinically and by laboratory and imaging investigations and followed-up during hospital stay till discharge. The cause of pain abdomen was ascertained by blood tests (amylase, lipase and liver function test etc, radiology (Flat plate abdomen-erect, Ultrasonography of abdomen, CECT abdomen and/or endoscopy. Results: Out of the 501 patients diagnosed as DF, 165 (32.93% presented with acute abdomen. Some patients presented in other departments like surgery, gastroenterology and emergency, were later diagnosed as DF on laboratory evaluation. Various causes of acute abdomen in our study were nonspecific severe pain abdomen (67 cases, acute hepatitis (46 one had acute fulminant hepatitis, acute acalculous cholecystitis (31, ascitis (12, acute hyperemic gastritis with malena (5, acute pancreatitis (2, and 1 case each of acute appendicitis and acute jejuno-ileal intussuception. All patients were managed conservatively. One patient of acute pancreatitis died of multi-organ failure. Conclusion: Our study concludes that clinical vigilance about such type of presentations is important as timely recognition can influence outcome and may prevent unwanted surgery.

    Acute abdomen caused by abdominal tuberculosis is a rare manifestation, and includes bleeding of a gastric or ileal ulcer, obstruction of the small bowel by an adhesive band, perforation of the ileum, ileocolic intussusception and fistula, and mesenteric abscesses caused by necrotic lymph nodes. The clinical and radiologic features of these complicated tuberculosis may mimic other acute abdominal diseases. Although not definitive, careful evaluation of the radiologic findings of the bowel wall, mesenteric fat infiltration, and lymph node enlargement may provide useful diagnostic clues to the presence of acute abdomen due to tuberculosis.

    Authors analyzed the distribution of diseases and compared ultrasonographic conclusions with confirmed diagnoses of emergency abdominal ultrasonographies in acute abdominal conditions. We evaluated the role of emergency abdominal ultrasonography especially in the decision of emergency operation. In one hundred and forty five patients, emergent abdominal ultrasonography was performed within on admission. We compared the sonographic conclusion with postoperative pathology and analyzed the diagnoses of medically treated diseases. Twenty-eight patients underwent surgery and 117 patients were treated conservatively. Among the surgically treated patients, 19 patients (70.4%) were correctly diagnosed by preoperative ultrasonography.These included acute appendicitis (N = 8), acute cholecystitis (n = 7), ovarian cyst torsion (n = 2), and liver abscess (n = 1). Correct preoperative diagnosis was not made in 9 patients, including acute appendicitis (n = 4), peritonitis due to bowel perforation (n = 2), ectopic pregnancy (n = 1), colonic diverticulitis (n = 1) and pelvic inflammatory disease (n = 1). Clinical follow up was possible in 50 patients among the non-operative patient group, and the clinical diagnoses were chronic liver disease (n = 14), acute pyelonephritis (n = 10), and biliary stone (n = 10). Emergent ultrasonography plays an important role in acute abdominal conditions by supporting the differential diagnosis of medical and surgical disease

  20. Patent Urachus Presenting as Acute Abdomen

    Full Text Available The urachus is an epithelial tubular structure located in the midline that spreads from the anterosuperior part of the bladder to the navel, connecting the apex of the urinary bladder with the allantois in the fetus, and is involved in forming the umbilical structures. When the urachal tract is not completely obliterated during embryonic development, bladder diverticulum, urachal cyst, umbilical polyp, or patent urachus may result. Therefore, making a differential diagnosis prior to surgery is not easy. A 30-year-old woman presented to the outpatient clinic with severe abdominal pain in the suprapubic and infraumbilical regions of 12 hours of evolution. There were no urinary symptoms, and she was afebrile. Physical examination revealed periumbilical tenderness and intense pain on abdominal palpation in the suprapubic and abdominal regions. An ultrasound scan revealed a patent urachus. The striated structure was present between the bladder and the umbilicus. After undergoing preoperative examinations, the patient was submitted to surgical treatment, and the final pathology of the resected segment confirmed the ultrasound diagnosis. Urachal pathology in adulthood is rare. Often its presentation as acute abdominal pain is nonspecific and, as such, may cause many diagnostic problems. Differential diagnosis should include acute appendicitis and other inflammatory disorders. The patient's history and physical examination are crucial for the correct diagnosis. It is important to have a thorough understanding of the embryology, anatomy, presentation, and relevant investigations for these anomalies. Ultrasound can be helpful for diagnosing the pathology of urachal remnants.

    Full Text Available Omental torsion leading on to omental infarction is an unusual cause of acute abdominal pain in adults. Often the condition mimics common causes of acute abdomen like acute cholecystitis, acute appendicitis or acute pancreatitis. A review of literature reveals that this enigmatic condition has been managed both non - operatively and by surgery in the past. We report the case of a 46 - year - old man who presented with a 4 - day history of severe right - sided abdominal pain mimicking acute cholecystitis. Abdominal CT scan revealed a right upper quadrant mass with a whirl - like appearance, suspicious for omental infarction. He was started on conservative management with analgesics and antibiotics. He improved symptomatically and was discharged

    A wandering spleen, defined as a spleen without peritoneal attachments, is a rare entity characterized by splenic hypermobility due to laxity or maldevelopment of the supporting splenic ligaments. Patients with a wandering spleen may be asymptomatic, or may present with a palpable mass in the abdomen, or with acute, chronic, or intermittent symptoms due to torsion of the wandering spleen. Because early clinical diagnosis is difficult, imaging modalities play an important role in the diagnosis. Treatment should be planned according to the vitality of the spleen. A 22-year-old woman presented with an acute abdomen that was found to be due to a wandering spleen with 720° anti-clockwise torsion around the pedicle. Splenectomy is advocated in the presence of torsion, splenic vein thrombosis, or splenic infarction. Conversely, when a viable wandering spleen is found at laparotomy, detorsion with splenopexy is preferred. Copyright © 2012 Elsevier Inc. All rights reserved.

    Lassa fever, an endemic zoonotic viral infection in West Africa, presents with varied symptoms including fever, vomiting, retrosternal pain, abdominal pain, sore-throat, mucosal bleeding, seizures and coma. When fever and abdominal pain are the main presenting symptoms, and a diagnosis of acute abdomen is entertained, Lassa fever is rarely considered in the differential diagnosis, even in endemic areas. Rather the diagnosis of Lassa fever is suspected only after surgical intervention. Therefore, such patients often undergo unnecessary surgery with resultant delay in the commencement of ribavirin therapy. This increases morbidity and mortality and the risk of nosocomial transmission to hospital staff. We report 7 patients aged between 17 months and 40 years who had operative intervention for suspected appendicitis, perforated typhoid ileitis, intussuception and ruptured ectopic pregnancy after routine investigations. All seven were post-operatively confirmed as Lassa fever cases. Four patients died postoperatively, most before commencement of ribavirin, while the other three patients eventually recovered with appropriate antibiotic treatment including intravenous ribavirin. Surgeons working in West Africa should include Lassa fever in the differential diagnosis of acute abdomen, especially appendicitis. The presence of high grade fever, proteinuria and thrombocytopenia in patients with acute abdomen should heighten the suspicion of Lassa fever. Prolonged intra-operative bleeding should not only raise suspicion of the disease but also serve to initiate precautions to prevent nosocomial transmission.

    Full Text Available Jejunal diverticulosis is a rare case that is diagnosed incidental. Although it is generally asymptomatic, it can cause non-spesific symptoms like stomachache, nausea, diarrhoea, malabsorption, bleeding, obstruction and / or perforation. Perforated jejunal diverticulitis is a very rare acute abdomen cause. The acute complications of jejunal diverticulosis can be cause of significant morbidity and mortality especially in old patients. In this text, we report a 81 year old woman case that was operated emergently because of perforated jejunal diverticulitis and was lost in postoperation term because of multiple organ failure.

    An acute abdomen is one of the main topics among emergency practice for children. We have experienced about 300 acute abdomen cases per year at our Children's Hospital since 1970. Radiological technologists provide a 24-hour emergency service using special knowledge and techniques in our radiological investigation. In the noenatal period esophageal atresia should be diagnosed by plain up-right film with a coiled-up rubber tube, and a contrast examination is contraindicated to prevent severe aspiration pneumonia. In the cases with intestinal atresia, the contrast examination is not necessary again, because the findings of plain film such as the distribution of air-filled intestinal loops, dilated bowel with air-fluid level gives us enough information for the diagnosis of these congenital anomalies. On the contrary, barium enema is useful and harmless for the neonatal age group. It is practical for diagnosing Hirschsprung's disease, midgut malrotation with volvulus, ileal and colonic atresia and necrotizing enterocolitis. An imperforate anus should be classified into the high and low type in the neonatal period to define the treatment. Invertogram is an only way for the differentiation of a baby without external fistula, and we have established the technique for this. The level is diagnosed by the relationship between the gas-filled rectal pouch and ischiac bone. In the infant group intussusception is the most common and urgent acute abdomen. We use a special device to fix the bady, dilute the barium with warm saline (to avoid water intoxication), limit the water pressure to within one meter, and avoid abdominal manipulation and longtime exposure. The successful reduction rate that our team has obtained is almost 85%.

  8. Hotel NHS and the acute abdomen - admit first, investigate later.

    2009-12-01

    To determine the financial consequences of a policy of admission first, followed by definitive investigation for patients with an admission diagnosis of suspected acute abdomen. Over a 1-month period, 122 patients were admitted with a suspected surgical diagnosis of acute abdomen (55 men, 67 women); age range 16-95 years (median: 56.5). Based on surgical operation required (n = 36), death after admission (n = 6, three postoperative deaths) and/or severe surgical illness (n = 17), 56 required surgical inpatient admission, while 66 did not. The patients who did not require admission spent significantly shorter time in hospital than those who required admission (median: 5 days vs. 8.5 days; p = 0.0000). Total hospital hotel and investigation cost (not including ITU or theatre costs) for all 122 patients was 330,468 pounds. Overall, 205,468 pounds was consumed by these 56 patients who required admission, while 125,000 pounds was spent on 66 patients whose clinical course did not justify admission; 92% of which was spent on hospital hotel costs and 8% on the cost of imaging and/or endoscopy. On a national basis, emergency General Surgery admissions account for 1000 Finished Consultant Episodes per 100,000 population. The findings of this study suggest that this equates to a national NHS spend of 650 million pounds each year, for the hotel costs of patients that could arguably avoid surgical admission altogether. Continuing to admit patients with a suspected acute abdomen first and then requesting definitive investigation makes neither clinical nor economic sense.

    Full Text Available Background: Acute tuberculous appendicitis is a rare disease. It constitutes from 0.001 % to 0.01 % of the clinical forms of tuberculosis. We present cases of such disease as probably cause for surgical acute abdomen. Case report: Male aged 29 with mild to moderate diffuse abdominal pain, which intensified and localized in the right lower quadrant of the abdomen, fever, vomiting, malaise, leukocytosis (11,300/µL and 91 % neutrophils. Appendectomy was performed, the histopathological report was acute appendicitis, Ziehl-Neelsen stain was positive. Three days later he returned home and had no short- or long term complications. Conclusion: Acute tuberculous appendicitis is a rare disease that may cause acute abdomen, patients should receive drug treatment to eradicate the cause and have proper epidemiological monitoring.

    Jejunal pseudo-diverticulosis is a rare acquired herniation of the mucosa and submucosa through weakened areas of the muscularis mucosa of the mesenteric aspect of the bowel. They are asymptomatic in the majority of cases; however, they can present with a wide spectrum of non-specific symptoms such as chronic abdominal discomfort, postprandial flatulence, diarrhoea, malabsorption and steattorhoea. In up to 15% of cases, more serious acute complications may arise such as the development of intestinal obstruction, haemorrhage or as in our case, localized peritonitis secondary to perforation. Perforation carries an overall mortality rate of up to 40% and exploratory laparotomy followed by copious lavage with segmental resection and primary anastomosis remains the mainstay of managing such sequalae of jejunal pseudo-diverticulosis. Our case report highlights the importance of maintaining a high clinical suspicion of a perforated jejunal diverticulum in an elderly patient presenting with an acute abdomen. PMID:27765806

    Uterus bicornuate unicollis is one of the various congenital abnormalities of the female genital tract caused by partial fusion of the mullerian ducts on both sides. A case of acute abdomen resulting from missed diagnosed bicornuate unicollis uterus in a 42-year infertile women was presented. The ultrasonographic diagnosis of twisted complex left adnexial cyst was made prior to exploratory laparotomy. However, findings at laparotomy revealed a non-communicating bicornuate unicollis uterus with damaged right tube (hyrosalpinx) and normal ovaries and left tube. A blind-ended rudimentary left sided uterine horn was excised with the ovary spared and the right sided hydrosalpinx disconnected using chromic 1. Patient was however counselled for in vitro fertilization.

    Acute epiploic appendagitis is a relatively rare cause of lower abdominal pain that clinically mimics other acute abdomen conditions that require surgery such as acute diverticulitis or appendicitis. Here, we report a case of a 50-year-old lady who presented with an unusual lower abdominal pain. Awareness of such a clinical condition with its characteristic imaging findings is important to avoid costly hospitalization, unnecessary antibiotic courses, and the morbidity and mortality associated with surgical procedures.

    To obtain the characteristic sonographic findings of ovarian hemorrhage and investigate the usefulness of ultrasonography in the diagnosis. Forty-nine cases presenting acute abdomen diagnosed as ovarian hemorrhage by ultrasonography or surgicopathological confirmation. We observed the size and margin of the ovary, size, pattern, shape, wall and internal echogenecity of the masses and the amount of hemoperitoneum. We also performed a color Doppler study to evaluate the blood flow pattern and resistive index (RI). The age of patients were between 21-41. Most symptoms occurred from days 14 to 30 of her menstrual cycle and were presented for less than 24 hours. Twenty patients had a history of intercourse shortly before the onset of the symptom. Thirty two cases involved the right ovary while the other 17 cases involved the left. All patients had a negative urine or serum hCG test except for 4 pregnant women. The size of the ovary was measured as mean 5.1 cm and marginal irregularly was noted in 36 cases. Mixed echoic solid masses were observed in 6 cases and variable echogenecity of cystic masses were seen in 43 cases. Maximal diameter of adnexal masses were measured as mean 3.95 cm. Internal echogenecity of cystic masses appeared as mainly heterogeneous (21). Twenty two cystic masses had a thick irregular wall and 17 had a thin smooth wall. Hypoechoic rim like halo surrounding was noted in 17 cystic masses. 17 cases seemed to have a small amount of hemoperitoneum, a moderate amount in 22 cases and a large amount in 9 cases. The blood flow pattern of cystic masses showed a rim (29) and spotty (8) pattern in the color Doppler study. Measured RI was 0.41 (mean). Fertile women with the complaint of acute abdominal pain, who has the laboratory data of negative hCG test, ultrasonographic findings of enlargement of ovary with irregular margin, heterogeneous echoic cystic mass, peripheral halo surrounding the mass, hemoperitoneum and low resistance index of peripheral blood

    Notwithstanding the significant advantages compared to open surgery, laparoscopic surgery was considered to be contraindicated in pregnant patients. Currently, there are opposing views on the safety of laparoscopic surgery during pregnancy, especially in last trimester. The aim of this study was to examine feasibility of laparoscopic surgery in pregnant women with acute abdomen. We retrospectively reviewed records of all patients who were admitted to the Emergency Department of Cerrahpasa Medical Faculty between January 1995 and January 2013. All clinical data of pregnant patient who underwent laparoscopic surgery were analyzed including inpatient records, operative reports, pathology records, and delivery information. Fourteen pregnant patients (mean gestational age 19.2 weeks, ranged from 9 to 33 weeks) who underwent laparoscopy for appendectomy (n=11), cholecystectomy (n=2), and diagnostic reasons (n=1) were included. Average time of delivery was 37.4 gestational weeks (range 35-40 weeks). Two patients had preterm labor. No complications such as uterine injury, fetal death, or maternal mortality were encountered during laparoscopic procedures Laparoscopic surgery can be safely performed at all trimesters of pregnancy. Laparoscopy may be useful in differentiation of acute abdominal pain in pregnancy and may decrease fetal loss due to delay in diagnosis. shorter operative time reduces negative effects of surgery on mother and fetus.

    Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding. (orig.) [German] Vaskulaere Pathologien sind seltene Ursachen fuer den klinischen Zustand eines akuten Abdomens. Liegt eine vaskulaere Erkrankung vor, ist jedoch aufgrund der hohen Mortalitaet eine zuegige Diagnostik von grosser Wichtigkeit. Bei den Erkrankungen der abdominellen Gefaesse sind arterielle von venoesen Ursachen zu unterscheiden. Ein Verschluss der A. mesenterica superior ist die haeufigste Ursache fuer die akute Mesenterialischaemie, daneben sind Blutungen in den abdominellen Gefaessprovinzen des arteriellen Gefaessbaums von Bedeutung. Venoese Pathologien betreffen thrombotische Verschluesse der Pfortader, der V. mesenterica und der V. cava.

    During the last three years 172 diagnostic laparoscopies (DL) were performed at our department in patients with an acute abdomen of unclear causes. This corresponds to 17% of all patients who underwent operation due to an acute abdomen in the same period. Always the indication for a diagnostic laparoscopy arose then, when the cause or the localization of the acute abdomen could not be found by conventional diagnostic methods. The advantages of DL were either the confirmation (93%) or the exclusion (7%) of the diagnosis "acute abdomen", the exact localization and simultaneously a definitive operative treatment of the cause by minimal invasive interventions (n = 109/65%). In these patients with acute abdomen the main causes were acute inflammations of gallbladder (n = 48) and appendix (n = 29), ulcus perforations (n = 9) and ileus (n = 9). The conversion rate amounted to 2.7%, the postoperative complication rate to 11% and the lethality rate to 1.8% in these patients. A new indication is the so-called "bedside laparoscopy" as means to control the postoperative course of mesenteric embolism (n = 9) and diffuse peritonitis (n = 3) in order to avoid the stress of a second-look operation for these seriously ill patients or to secure the indication for relaparotomy.

    Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup. Appendicitis and complicated biliary pathology are the most frequent causes of non-obstetric acute abdomen in the pregnant patient. The decision to operate, the timing, and the surgical approach are essential for a correct management of this pathology. The aim of this paper is to perform a review and update on the diagnosis and treatment of non-obstetric acute abdomen in pregnancy. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U.

    In patients with acute thrombo-embolic occlusion of the superior mesenteric artery, catheter-assisted thrombolytic therapy represents a procedure of increasing importance in addition to surgery and intensive care treatment. The thrombolytic drugs utilized for this purpose are urokinase, streptokinase and recombinant tissue plasminogen activator (rtPA). Therapeutic embolization is predominantly used in the treatment of arterial bleeding from the gastro-intestinal tract, the liver, the intestines (due to an aneurysm or vascular malformation) and in bleeding from intestinal anastomoses. Polyvinyl alcohol particles, embospheres, gelfoam and microcoils can be utilized as embolic agents. Percutaneous transhepatic cholangiodrainage and stent implantation are applied in patients with biliary obstructions caused by inoperable tumors of the gall bladder or bile ducts, of the pancreatic head or duodenum and by metastases located in the liver parenchyma or hepatic hilum. Image-guided percutaneous drainage is a valuable option in the management of abscesses in the peritoneal cavity; less common indications are lymphoceles, biliomas, urinomas, hematomas, necrosis and pseudocysts.

    Full Text Available Wandering spleen is a rare condition that accounts for less than 0.25% of all indications for splenectomy. It is characterized by ectopic localization of the spleen owing to the lack or weakening of its ligaments. Torsion is the most common complication due to its long pedicle and high mobility, which may result in acute abdomen. We report a case of torsion in a wandering spleen in a 28-year-old male presenting with an acute abdomen that was treated by splenectomy.

    Visceral involvement in acute non-lymphocytic leukemia (ANLL) seldom precedes hematological manifestation. We report on a patient with M4 - ANLL presenting with acute abdomen without any evidence of blood disorder. Laparotomy revealed only ileal wall oedema. Postoperative clinical deterioration led to a second-look operation combined with intraoperative endoscopy. Biopsied tissues were diffusely infiltrated by blasts characterised as HLA-DR (+), PGM1 (50% +), MPO (50% +) and CD 34 (-). Bone marrow reconfirmed these findings and showed positivity for CD4 (44%), CD11b (50%), CD11c (42%), CD13 (33%), CD34 (32%), and CD56 (54%). Chemotherapy achieved a complete but short remission. Relapse occurred 7 months later. Immediately after consolidation chemotherapy the profoundly immunosuppressed patient passed away after a lower respiratory tract infection. We discuss the contrast between histology and short disease duration, the unusual presentation and the bad prognosis, and attempt to correlate the clinical course with the coexpression of markers.

    To assess the incidence and diagnostic role of hyperechoic inflammatory fatty tissue (HIFT) in transabdominal ultrasonography (TAUS) for acute abdomen. With TAUS, we examined 98 consecutive patients (68 women, 30 men: mean age, 32 years: age range, 4-84 years) having acute abdominal pain. We examined the abdomen and pelvis by TAUS to determine the cause of acute abdomen, to check for the presence of HIFT, and to investigate whether it was easier and earlier to find the main cause and HIFT presence. We also prospectively evaluated the shape, distribution, and diagnostic role of HIFT. Final diagnoses consisted of 47 cases of acute appendicitis, 14 of enterocolitis, 13 of PID, 7 of gynecological hemoperitoneum, 5 of colonic diverticulitis, 3 of ovarian torsion, 2 of colon perforation, 2 of only presence of non-specific HIFT, 1 of mesenteric lymphadenitis, and 4 of normal. HIFT were seen in 67 patients (68.4%), including 44/47(93.6%) of acute appendicitis, 2/14(14.3%) of enterocolitis, 11/13(84.6%) of PID, 0/7 of hemoperitoneum, 5/5 of colonic diverticulitis, 0/3 of ovarian torsion, 2/2 of colon perforation, and 1/1 mesenteric lymphadenitis. HIFT were detected earlier than the main cause in 17/44 of acute appendicitis, 6/11 of PID, and 4/5 of colonic diverticulitis. In acute appendicitis, the shape of HIFT appeared as fat thickening along the mesoappendix in 12/44, fat thickening along the mesoappendix and the opposite side in 13/44, fat encircled appendix in 6/44, fatty mass wrapping abscess in 10/44, and diffuse intraperitoneal fat thickening in 3/44. In PID, HIFT appeared as a single fatty mass in the pelvis and lower abdomen in 6/11, wrapping pelvic abscess in 2/11, and multiple fatty masses scattered in abdomen and pelvis in 3/11. In colonic diverticulitis, all 5 cases appeared as hyperechoic hemispheric mass covering the inflamed diverticulum. HIFT are a usual US finding in patients with acute abdomen, particularly on abdominal and pelvic inflammatory conditions

    Full Text Available It is known that lower lobe pneumonia may result in a picture of acute abdomen; however, it can be easily overlooked when there are no signs or symptoms of the respiratory system. This case has been reported to remind the reader of the possibility of lower lobe pneumonia in patients presenting with a picture of acute abdomen. A ten-year-old male patient presented to our emergency outpatient clinic with the symptom of severe stomach ache that had started 2 days previously. The abdominal examination showed sensitivity, rebound, and defense. The examination results for his respiratory system and other systems were normal. The anterior-posterior pulmonary x-ray and direct abdominal x-ray in standing position were normal. No signs of acute abdomen could be seen in his abdominal ultrasonography. Lower lobe pneumonia was identified in his abdominal CT. It is difficult to diagnose pneumonia in patients who present with a picture of acute abdomen if there are no symptoms and x-ray signs related to the respiratory system. Anamnesis and physical examination are key to reaching an accurate diagnosis in such patients; however, any delay in diagnosis can be prevented by requesting further studies such as CT if the diagnosis cannot be ascertained by physical examination.

The patient had been complaining of mild abdominal pain for several months that had suddenly become severe. Early diagnosis at the emergency room was acute appendicitis, but definitive diagnosis was bilateral ovarian teratoma. We therefore recommend considering ovarian teratomas in the differential diagnosis of acute abdomen in young women in an emergency care setting.

    We present the case of a 58-year old male patient admitted in the surgery section of the University Emergency Hospital of Bucharest and diagnosed with acute abdomen. The minimal clinical-paraclinical investigation (i.e., thorax-pulmonary Xray, biological probes) raises questions as to the differentiated diagnosis and other associated diseases, also suggesting the existence of voluminous diaphragmatic hernia. The CT thorax-abdomen examination confirms the diaphragmatic hernia suspicion, with intra-thorax ascent of the colon up to the anterior C4 level, but does not explain the abdominal suffering; thus we suspected a biliary ileus or acute appendicitis. Medial laparotomy was imperative. Intrasurgically peritonitis was noticed located by gangrenous acute apendicitis, perforated, with coprolite, for which apendictomy and lavage-drainage pf the peritoneal cavity was performed. Post-surgical status: favourable to recovery.

  14. Acute Abdomen Due to Uncontrolled Use of Warfarin: Spontaneous Intra-abdominal

    2017-12-01

    Full Text Available Warfarin is an oral anticoagulant, which is commonly used in the treatment and prophylaxis of thromboembolic conditions. Bleeding is the primary adverse effect associated with warfarin. The majority of warfarin-related bleedings are spontaneous minor hemorrhages occurring in the subcutaneous or intramuscular tissues and can be treated by decreasing the dose of oral anticoagulants. However, although rare, it is possible to encounter spontaneous major bleedings with increased risk of mortality. Conservative approach is the preferred initial therapy for hemodynamically stable patients with major intra-abdominal hemorrhages that we define as the intermediate group patients. Nevertheless, surgery is required for hemodynamically unstable patients with acute abdominal pain in cases of ongoing active hemorrhage, generalized peritonitis, obstruction, acute abdomen, intestinal ischemia, and perforation. In this article, we present a rare case of acute abdomen and spontaneous intra-abdominal hemorrhage resulting from uncontrolled use of warfarin and a new classification requirement.

    Full Text Available Background: Acute abdomen in children has been aptly described as Pandora′s box. Unlike computerized tomography (CT scan, ultrasonography (USG has no radiation hazard and the present study analyses the diagnostic yield of the USG in acute abdomen in children. Materials and Methods: Between September 2001 to October 2003, 75 patients with acute abdomen underwent clinical examination, routine biochemical tests, erect X-ray abdomen, USG and CT scan. Laparotomy and histological examination established final diagnosis. Results: The accuracy of correct diagnosis was 60%, 66.6%, 64%, 98.7% with clinical examination alone, USG alone, clinical examination combined with conventional radiography, and clinical evaluation combined with conventional radiography and USG respectively. USG helped to prevent unnecessary laparotomy in 16.3% of patients. Conclusions: USG is good investigative modality in the management of acute abdomen in children.

    Full Text Available Idiopathic isolated cecal necrosis is a clinical problem characterized by right-sided inferior abdominal pain. It is rarely seen, develops due to decreased blood flow to the colon and, imitates acute appendicitis. Its clinical signs are similar to many illnesses causing sensitivity in the right inferior quadrant and, the diagnosis is generally determined during surgery. An 86-year-old male patient presented with the complaints of abdominal pain, trichiniasis, nausea and vomiting. Surgical intervention was decided when physical examination and laboratory results were taken into consideration. After diagnostic laparoscopy, right hemicolectomy was performed because of cecal necrosis. While the mortality and morbidity rates for ischemic bowel disease are high, prognosis for early diagnosed patients with isolated cecal necrosis is better, provided that timely surgical treatment is decided.

    Full Text Available Spontaneous perforation of the uterus is rare, its incidence being about 0.01%–0.05%. We report a rare case of diffuse peritonitis caused by spontaneously perforated pyometra. A 63-year-old woman with severe abdominal pain was admitted to our hospital. Laparotomy was performed because of the suspicion of gastrointestinal perforation with generalized peritonitis. At laparotomy, about 900 mL of pus was found in the peritoneal cavity. There were no abnormal findings in the alimentary tract, liver, or gallbladder. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Pathological investigation of the surgical specimen revealed endometritis and myometritis of the uterus; but there was no evidence of malignancy, and the cervical canal was patent. Although spontaneously perforated pyometra is rare, a perforated pyometra should therefore also be considered when elderly women present with acute abdominal pain.

    Full Text Available Spontaneous spleen rupture is a rare complication of infectious diseases and it can become a potentially life-threatening condition if not diagnosed in time. A 17-year-old Greek female presented to the ER due to acute abdominal pain, mainly of the left upper quadrant. She had no recent report of trauma. The patient was pale, her blood pressure was 90/70 mmHg, and her pulse was 120 b/min. Clinical examination of the abdomen revealed muscle contraction and resistance. The patient was submitted to an ultrasound of the upper abdomen and to a CT scanning of the abdomen that revealed an extended intraperitoneal hemorrhage due to spleen rupture. Due to the patient’s hemodynamic instability, she was taken to the operation room and splenectomy was performed. Following a series of laboratory examinations, the patient was diagnosed to be positive for current cytomegalovirus infection. The postoperative course was uneventful, and in a two year follow-up the patient is symptom-free. Spontaneous spleen rupture due to Cytomegalovirus infection is a rare clinical entity, described in few case reports in the world literature and should always be taken into consideration in differential diagnosis of acute abdomen, especially in adolescents with no recent report of trauma.

Sonography is the method of choice for the assessment of cholecystitis, whereas magnetic resonance cholangiopancreaticography (MRCP) is the standard technique to detect stones in the common bile duct. Multi-detector computed tomography (MDCT) is ideal for detection of associated complications, including abscess formation and gall stone ileus. Pyogenic, amebic and fungal liver abscesses are reliably diagnosed with MDCT which can also be used for interventional radiologic therapy of liver abscesses by percutaneous aspiration or drainage procedures. The second most common cause of liver rupture after blunt trauma is spontaneous rupture of hypervascular liver tumors (i.e., HCC, adenoma, angiosarcoma) and due to medical procedures. Multi-phase contrast-enhanced MDCT can reliably detect active bleeding to guide further therapy in these cases. (orig.)

    Full Text Available The present case report demonstrates a laparoscopic approach to treat interstitial cornual pregnancy in emergency. Interstitial ectopic pregnancy develops in the uterine portion of the fallopian tube which accounts for 2–4% of all ectopic pregnancies and has the potential to cause life-threatening hemorrhage at rupture. The mortality rate for a woman diagnosed with such a pregnancy is 2–2.5%. Diagnosis of interstitial pregnancy is made by ultrasound. In this case a 32 year-old woman, Gravida 0 Parity 0 Living 0 Ectopic 1, presented to the emergency obstetrical room complaining acute abdominal pain. There was a history of 10 weeks of pregnancy but no pelvic ultrasound scan was performed before the access. A transvaginal ultrasound scan immediately performed demonstrated a gestational sac with viable fetus in the right interstitial region. Moreover there was an ultrasound evidence of hemoperitoneum. She was transferred to the operating room and an emergency laparoscopy surgery was performed. The postoperative course was uneventful and the patient was discharged two days after the surgery. Interstitial pregnancies present a difficult management problem with no absolute standard of care in literature. Laparoscopic technique is under study with favorable results. For our personal point of view a treatment via laparoscopy could be performed both in elective and in emergency cases.

    Pyometra is an uncommon and potentially lethal disease that occurs mainly in postmenopausal women. Spontaneous perforation of pyometra presenting as acute abdomen is an extremely rare complication of pyometra, and the patients are always admitted to the emergency department. An additional case is reported herein. In addition, a literature review was performed between 1949 and 2015. A correct preoperative diagnosis was made in 21.05% of all the cases. Of all cases, 25.71% were associated with malignant disease. The mortality rate of spontaneous perforation of pyometra is 31.88%. Thus, it should be considered in the differential diagnosis of acute abdomen in elderly women. Total hysterectomy along with bilateral salpingo-oophorectomy is the preferred treatment. Administration of broad-spectrum antibiotics and postoperative intensive care support are essential to reduce the high mortality.

    Rhabdomyolysis is characterized by muscle necrosis and release of intracellular constituents, causing muscle pain, weakness, and myoglobinuria. This can be attributed to muscle injury after strenuous exercise. If the abdominal wall is involved, clinical presentation may resemble an acute abdomen. A 27-year-old woman, gravida 4 para 2, presented with swelling and pain of the mons pubis and abdominal pain after intense powerlifting 2 days prior. A computed tomography scan was performed, revealing abdominal wall inflammation. Although myoglobinuria was absent, there was high suspicion for rhabdomyolysis, which was confirmed by an elevated creatine kinase level. The patient improved after receiving intravenous fluids and abstaining from physical activity. Abdominal wall muscle injury resulting in rhabdomyolysis can imitate an acute abdomen in a healthy woman presenting with abdominal pain and swelling.

    Cystic lymphangioma of the small bowel mesentery is a rare clinical entity, especially after childhood. Medical literature reveals a limited number of such cases presenting as acute abdomen due to bowel obstruction, small bowel volvulus and bleeding into the tumour. We present the management experience of an 18-year-old woman who presented with rapid onset diffuse peritonism and raised inflammatory markers. Computed tomography showed a mass in the small bowel mesentery with suspicion of segmental bowel ischaemia. Emergency laparotomy revealed a mass in the mid-jejunal mesentery close to the bowel wall with no bowel ischaemia. The patient made an uncomplicated recovery after segmental bowel resection and end-to-end anastomosis. Histology confirmed the mass as a cystic lymphangioma involving the jejunal mesentery and two small jejunal polyps. Lymphangioma could be considered in the differential diagnosis of an acute abdomen in a young adult when the presentation is atypical.

    We report the case of an immunocompromised 15-year-old boy who presented with symptoms mimicking an ``acute abdomen`` related to necrotizing myofasciitis of the anterior abdominal wall. CT demonstrated the abdominal wall process as the cause of the patient`s symptoms and sonographically guided aspiration confirmed the diagnosis. Despite prompt diagnosis and aggressive surgical debridement, the infection continued to progress and the patient died within 24 h of presentation. (orig.) With 1 fig., 16 refs.

    Full Text Available Abdominal pain continues to pose diagnostic challenges for emergency clinicians. A 56-year-old Japanese woman was referred to our hospital due to severe abdominal pain which presented as occasional epigastric pain five months before and intermittent abdominal pain. She had a past history of ileus twice, for both of which laparotomy was performed without an alimentary tract resection. The wall thickening with marked three-wall structure from terminal ileum to sigmoid colon was seen and bladder wall was irregularly thick and enhanced irregularly. Among the differential diagnosis of the acute abdomen, autoimmune diseases were suspected, especially lupus erythematosus and Henoch-Schönlein purpura. On the second day of admission, abdominal pain worsened. The results of examinations of antinuclear antibody, anti-double-stranded DNA antibody, ANCA, and the complements were not obtained at that time; however, we started 1-g steroid pulse treatment for three days with success. With the results obtained later, the patient was given a diagnosis of probable systemic lupus erythematosus (SLE. The present case shows that SLE can present with acute abdomen and should be included in the wide range of the differential diagnosis of acute abdomen.

  7. A rare cause of acute abdomen – Spontaneous rectus sheath hematoma

    Full Text Available Spontaneous rectus sheath hematoma (SRSH is a rare entity that mimics acute abdomen. Rectus sheath hematoma is the accumulation of blood in rectus sheath due to muscle or epigastric vessel injury. However, SRSH without a trauma or anticoagulation is rare. It frequently mimics acute abdomen and it may lead to misdiagnosis and unnecessary laparotomy. In this article, we described two cases of SRSH with their diagnostic and therapeutic strategy. Both of our patients in report were neither consumed antiplatelet nor coagulopathy. They both had abdominal muscle straining before their symptoms presentation. We hypothesized that the SRSH may be induced by rectus muscle injury secondary to inappropriate straining or posture. To diagnose SRSH, clinical findings are important but radiologic imaging such as computed tomography, can be diagnostic. In expanding SRSH, percutaneous arterial embolization of epigastric artery is useful to secure the bleeding. If embolization is not feasible, surgical exploration hemostasis is curative. In non-expanding SRSH, it can be managed nonoperatively. SRSH is an important initial differential for acute abdomen. Radiologic imaging helps in diagnosis. Stable SRSH can be managed conservatively with good outcome.

    Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis (OHVIRA) or Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital urogenital anomaly. A 13-year-old female presented with acute abdominal pain and dysmenorrhea. Ultrasonography and magnetic resonance imaging showed uterus didelphys, hematometrocolpos, obstructed hemivagina, and right renal agenesis. Hemivaginal septal resection and anastomosis between the obstructed hemivagina and the normal vagina was tried, but it was not possible. Unilateral hysterectomy was performed. HWW syndrome may present with acute abdomen and is usually treated with vaginal septum resection and drainage of the hematometrocolpos. Copyright © 2014 Elsevier Inc. All rights reserved.

    1994-12-01

    As a cause of small intestine occlusion, volvulus is often a consequence of a band or adhesions. Except in infants, it is rarely the primary cause of symptomatology. Between January 1976 and December 1992, 13 patients (7 women and 6 men, mean age of 56.8 years) were admitted in our department for an acute abdomen due to a spontaneous primary volvulus of the small bowel. Clinical examination and laboratory tests did not help in preoperative diagnosis. All patients underwent an explorative laparotomy. Six patients had had prior abdominal surgery but none of them presented adhesion or band. In 8 patients (62%), detorsion was sufficient. Resection of a segment of small bowel was necessary in 4 patients. Gangrenous of the entire bowel was observed in one patient who rapidly died. Two patients presented minor complications. One patient with Down syndrome died of bronchoaspiration. One patient has been reoperated on one year later for recurrence of the volvulus, and underwent a Noble procedure. We conclude that volvulus of the small bowel is a rare cause of acute abdomen that must be remembered. Early surgery is mandatory to reduce the risk of gangrene, which is known to double the mortality. Laparoscopy will be helpful in early diagnosis and therapy.

    Full Text Available Acute abdomen with hemoperitoneum is a very rare entity in postmenopausal women due to gynecologic conditions. A 54-year-old, postmenopausal woman was brought to emergency department with severe abdominal pain. Physical examination revealed acute abdomen findings with 15 cm pelvic mass on the right adnexal region. Immediate exploratory laparotomy was performed. During laparotomy 1000 cc of bloodstained fluid, ruptured and actively bleeding large mass arising from right ovary was observed. Right salpingo-oopherectomy was performed in emergency conditions, and pathology report revealed an adult type of granulosa cell tumor. After this result, staging surgery was performed and patient was diagnosed as granulosa cell tumor stage 1 c. Cisplatin, etoposide, and bleomycin chemotherapy was given. Clinicians should be aware of granulosa cell tumors which may occur at any age and prone to rupture. Frozen section will be helpful in order to avoid incomplete surgeries especially in postmenopausal women presented with intra-abdominal bleeding.

    Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract, occurring in 2-3% of the population. Enterolith formation associated with MD is a rare entity. We present the case of a 35-year-old active duty sailor who presented with a 24-hour history of worsening abdominal pain and nausea. His exam revealed lower abdominal peritonitis. An abdominal and pelvic CT scan revealed a fluid-filled structure in the pelvis adjacent to the distal small bowel with associated calcifications. Exploratory laparotomy was performed, which revealed an acutely inflamed MD associated with enterolith formation. Consideration of this condition in the differential upon presentation of an acute abdomen is essential, secondary to the morbidity that can accompany it when misdiagnosed.

    Two different series collected at the University Hospital of Freiburg are presented as a basis for the critical appraisal of available imaging tests and their correlation with anatomic pain sites. The first series comprises 284 patients of non-traumatic acute abdomen admitted to the emergency department during 1990. The radiological approach revealed an increased use of immediate ultrasound (58%) followed by plain film radiography (53%), contrast studies (15%), and computed tomography (9.8%). Five groups of entities were identified according to the diagnostic imaging procedure prior to surgery. In a second series, the clinical presentation, the distribution and the efficacy of imaging studies for the confirmation of acute mesenteric ischemia were evaluated in 55 patients over a period of 14 years. A reduced mortality rate emphasizes the value of early and agressive diagnosis and angiographic management. (orig.)

    Full Text Available BACKGROUND The most common causes of the acute abdomen are acute appendicitis which may be perforated, typhoid ileal perforation, acute intestinal obstruction, gastroduodenal perforations, nonspecific abdominal pain, abdominal injuries, and acute cholecystitis. A summary of all the acute complications taken together will be the fact that all are associated with post-surgical complications. A sincere effort has been made to study the post-operative complications that a surgeon encounters while treating the acute abdomen cases. This study is intended to help the practising surgeons who deal with such complications. It also is intended to help the doctors who practice to identify such complications and thus refer the patients for immediate intervention. METHODS This study was conducted in the Department of General Surgery, Government Medical College, Nizamabad, Telangana. This study was done from June 2013 to May 2016. One hundred sixty patients who were admitted in the hospital after surgery for acute abdominal conditions were considered for the study. Thorough clinical examination was conducted and the complications that were encountered were noted and the complications were treated as per the need of the hour. The complications faced by the treating surgeon in each and every entity that was discussed earlier was duly noted and statistical analysis was conducted. All the statistical analysis was done using the latest SPSS software 2015 (California. RESULT In our study, the mean age of the study population was found to be 29.8 years. That means the majority of the patients who turn up in the Department of Emergency is young and generally in the third decade of life. In Acute Intestinal Obstruction and blunt abdominal injuries, significance of mortality is high (p<0.05. CONCLUSION The study was successful in proving that abdominal injuries are the main factors of causing morbidity and mortality in the younger generation. The surgical mode of

    Full Text Available Meckel’s diverticulum is the most common congenital anomaly of the gastrointestinal tract. In this report, we aimed to represent a case of intestinal perforation, caused by double Meckel’s diverticulum, which is a very rare entity in surgical practice. The patient was a 20-year-old Caucasian man, admitted to hospital with complaints of abdominal pain, nausea, and vomitting during the last 3 days. Physical examination indicated tenderness, rebound, and guarding in the right lower quadrant of abdomen. Abdominal X-ray revealed a few air-liquid levels in the left upper quadrant. In the operation, 2 Meckel’s diverticula were observed, one at the antimesenteric side, at 70 cm distance to the ileocecal valve, approximately in 3 cm size, and the other between the mesenteric and antimesenteric sides, approximately in 5 cm size. The first one had been perforated at the tip and wrapped with omentum. A 30 cm ileal resection, including both diverticula with end-to-end anastomosis, was performed. The diagnosis of symptomatic Meckel’s diverticulum is considerably hard, especially when it is complicated. Diverticulectomy or segmentary resections are therapeutic options. In patients with acute abdomen clinic, Meckel’s diverticulum and its complications should be kept in mind, and the intestines should be observed for an extra diverticulum for caution although it is a very rare condition.

    Full Text Available Introduction: Heterotopic pregnancy is a life threating condition of intrauterine and extrauterine gestations which occur at the same time. We report a delayed diagnosed case of heterotopic pregnancy. Case: A 31 year-old primigravida was referred to our Emergency Gynaecology Service complicated by acute abdomen. She had been treated with clomiphene citrate and on admission intrauterine a missed abortus of about 8 weeks complicated by a large subchorionic hematoma was detected. Emergency laparotomy was performed because of diffuse intra-abdominal haemorrhage. A right-sided ectopic focus was recognized and excised, and dilatation - curettage was performed. Coclusion: Delay in diagnosing the condition can be fatal to both the mother and the intrauterine fetus. [J Contemp Med 2013; 3(3.000: 207-208

    Introduction Hemangioma is the most common benign tumor of the liver. Most cases are asymptomatic and do not require treatment. A hemangioma can rarely be pedunculated; as a result, it may undergo torsion and infarction, which can make it symptomatic. Case Presentation We report the case of a 45-year-old woman with acute abdominal pain due to torsion of a giant pedunculated hepatic hemangioma around its vascular stalk. Conclusions Pedunculated hemangioma of the liver is an uncommon benign tumor, a rare differential diagnosis for a mass located in the upper abdomen. All incidentally detected pedunculated hemangiomas must be surgically managed, as these have a tendency to become torsioned, and there is also a risk of malignancy or rupture. PMID:27781125

    Full Text Available Gastrointestinal (GI perforation accounts for over 90% of acute abdomen and pneumoperitoneum. The presence of pneumoperitoneum secondary to spontaneously perforated pyometra is an interesting yet confusing finding given the absence of gastrointestinal (GI perforation, because pyometra is more common in postmenopausal women. We report an instructive case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 70-year-old postmenopausal female was admitted to surgical emergency with signs of diffuse peritonitis. After resuscitation, an emergency laparotomy was performed because of suspicion of GI perforation. At laparotomy, about 2,000 mL of purulent fluid was found to be present in peritoneal cavity, while GI tract was intact. A rent with a diameter of 5 mm was found on anterior fundus of uterus. A total abdominal hysterectomy with a bilateral salpingo-oophorectomy was performed. Despite intensive care and a course of antibiotics, the patient died of multiple organ failure resulting from sepsis on postoperative day 16. Our case illustrates the importance of clinical knowledge of acute gynecological diseases, which are not uncommonly encountered by the general surgeon. Moreover, good appreciation of pelvic anatomy and close collaboration with gynecology and GI surgery colleagues is essential as operative intervention is often required.

    Full Text Available Bowel perforation is an emergency problem, it presents as an acute abdomen. Computurize tomography (CT is important imaging modality used to evaluate patients with acute abdomen. CT shows anatomical detail and intestinal wall, evaluating secondary signs of bowel disease within the surrounding mesentery and detecting even small amounts of extraluminal air or oral contrast leakage into the peritoneal cavity. The aim of this article is to illustrate acute abdominal CT findings due to FOLFIRI therapy of a patient with colorectal cancer. Interestingly, this patient was an emergency case based on radiologic findings, but he felt good, had no emergency problem clinically. [Cukurova Med J 2016; 41(0.100: 88-91

    Summary Background Jejunal diverticulosis is a rare, usually asymptomatic disease. Its incidence increases with age. If symptomatic, diverticulosis may cause life-threatening acute complications such as diverticulitis, perforation, intestinal hemorrhage and obstruction. In this report, we aimed to present a 67-year-old male patient with jejunal diverticulitis accompanying with abdominal pain and vomiting. Case Report A 67-year-old male patient complaining of epigastric pain for a week and nausea and fever for a day presented to our emergency department. Ultrasonographic examination in our clinic revealed diverticulum-like images with thickened walls adjacent to the small intestine loops, and increase in the echogenicity of the surrounding mesenteric fat tissue. Contrast-enhanced abdominal computed tomography showed multiple diverticula, thickened walls with showing contrast enhancement and adjacent jejunum in the left middle quadrant, increased density of the surrounding mesenteric fat tissue, and mesenteric lymph nodes. The patient was hospitalized by general surgery department with the diagnosis of jejunal diverticulitis. Conservative intravenous fluid administration and antibiotic therapy were initiated. Clinical symptoms regressed and the patient was discharged from hospital after 2 weeks. Conclusions In cases of diverticulitis it should be kept in mind that in patients with advanced age and pain in the left quadrant of the abdomen, diverticular disease causing mortality and morbidity does not always originate from the colon but might also originate from the jejunum.

    Full Text Available Background. Mayer-Rokitansky-Kuster-Hauser (MRKH syndrome is a malformation of female genital tract (incidence 1 in 4000 female newborn children. It appears as a result of a disorder in the development of Millerian cannals. Etiology is unknown. Syndrome MRKH is the most frequent cause of primary amenorrhoea (90%. Patients with MRKH have a normal female phenotype, with normal pubic hairness and thelarche, and female karyotype (46XX followed by primary amenorrhoea. Hormonal status corresponds to healthy women, where the appearance of ovarian tumors and tumors on rudiment parts of uterus is possible. Case report. We presented a case of acute abdomen in a patient with previously not diagnosed MRKH. The diagnosis was done during the operation. Small pelvis and an abdominal part were filled with torquated tumor lump, where ovaries, oviducts, uterus or something resembling rudiment of uterus were not recognized through careful examination. Furthemore, the patient had a short, dead-end vagina. Tumorectomy was done and hystopathological finding showed the presence of vascular leiomyoma. Conclusion. The diagnosis of complex syndromes, such as MRKH, can, despite modern diagnostics, be absent for non-medical and psycho-social reasons. We can expect ovarian and uterine pathology on hypoplastic structures in these patients, as well as in healthy women. Vascular leiomyoma in the patients with MRKH was not found in the available literature.

    Full Text Available Ingestion of foreign bodies is not an uncommon occurrence, but most of them will pass through the gastrointestinal tract without consequences. Complication such as perforation is rare. We present a case of small bowel perforation secondary to the accidental ingestion of a chicken bone. The patient presented with abdominal pain, constipation and vomiting. Clinical examination confirmed generalized abdominal tenderness and rebound tenderness. Abdominal radiography showed multiple dilated loops of small bowel, and abdominal ultrasound (US showed inflammatory changes on small bowel loops, with free fluid and fluid collection around intestinal loops. The patient underwent an emergency laparotomy. Intra operative findings revealed diffuse fibro purulent peritonitis with abscess between central small bowels loops. At about 60 cm from Bauchini valve we found a perforation of ileum at the anti-mesenteric site caused by a sharp chicken wishbone. The patient was treated with resection of the ileum segment (10 cm and primary end-to-end anastomosis. Even that intestinal perforation by a foreign body is rare, physicians should consider possibility of intestinal perforation by a foreign body in the differential diagnosis of acute abdomen in patients presenting with abdominal pain.

    Lung cancer represents the leading cause of tumor death in the world with 50% of patients presenting metastatic disease at the time of diagnosis. Gastrointestinal (GI) lung cancer metastasis were thought to be extremely rare, but a much higher incidence has been noted in several autoptic reports. Clinical relevance of GI metastasis is low, but can increase with the higher number of newly diagnosed patients and with the efficacy of systemic chemotherapy in advanced stages. Prognosis of complicated GI lung cancer metastasis seems to be worse than the natural course of the disease and acute bleeding or perforation of metastatic site can be accelerated by chemotherapy. We describe the clinical case of a patient presenting with acute abdomen due to small bowel perforation from GI lung cancer metastasis. A review of the most recent published literature on GI lung cancer metastasis was performed. GI metastasis from lung cancer may occur within the clinical course of the disease and require surgical treatment followed by a poor outcome. Percentage of lung cancer patients with GI metastasis can reach level of 14%. Large cells carcinomas causing kidney and adrenal metastasis are more likely associated with GI localization of the disease. Complications of GI metastases, although rare, must be considered as possible cause of acute abdomen in patients with lung cancer. Identification of clinical indicators of GI metastasis may help in the therapeutic strategy.

    A leading cause of maternal mortality in the first trimester is hemorrhage due to a ruptured ectopic pregnancy. With the advent of tube salvage surgery, ectopic pregnancies can be removed while ensuring hemostasis and preserving the integrity of the fallopian tube. A major drawback of tube salvage surgery is the significant risk of persistent trophoblastic tissue being left behind. We report a case of a 30year old female who presented to the ED with acute abdomen and hemoperitoneum due to a ruptured ectopic pregnancy. She was treated with salpingostomy and the pathologic report confirmed removal of the ectopic pregnancy. After an initially uneventful post-operative recovery, she presented to the ED 27days later with signs of acute abdomen and hemoperitoneum. Surgical intervention confirmed a ruptured ectopic pregnancy in the same site as previous, and salpingectomy was performed, after which the patient recovered without complications. The increased risk of persistent trophoblastic tissue associated with tube salvage surgery can lead to subsequent reoperation for tubal rupture. Patients undergoing these procedures should be closely monitored in the following weeks and undergo serial β-hCG testing in order to confirm successful removal of the ectopic.

  6. Meckel’s Diverticulitis as a Cause of an Acute Abdomen in the Second Trimester of Pregnancy: Laparoscopic Management

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Introduction. Meckel’s diverticulitis is an extremely rare cause of an acute abdomen in pregnancy. Its clinical presentation tends to be rather unusual and therefore commonly delaying diagnosis. The surgical method of exploration can be either by laparoscopy or through an open incision. Case Report. We report a case of a 34-year-old, P1 with previous Caesarean section, who presented at 20 weeks with worsening right-sided abdominal pain, distention, and peritonism. Ultrasound scan showed an area of a possibly thickened loop of bowel inconsistent with an appendicitis. The findings at laparoscopy were purulent fluid in the pelvis, a congested appendix, and inflamed Meckel’s diverticulum. An appendectomy and excision of the diverticulum was performed using stapler technique. Discussion. Meckel’s diverticulitis in pregnancy can have nonspecific presentation and poses difficulties for preoperative diagnosis. Delay in diagnosis and management poses significant maternal and fetal risks. The use of laparoscopy if the gestational age and uterine size permit its use allows a thorough exploration of the abdominal cavity and management of rarer and unexpected pathology. Laparoscopic management of acute abdomen in the midtrimester of pregnancy has been found to be safe and effective.

    2012-09-01

    Full Text Available Introduction: Acute surgical abdomen is one of the most common emergency surgical causes all over the world and also one of the most important abdominal pain causes which is sometimes intolerable for the patients referring to the emergency departments. Diagnosis and planning for operation in these cases is based on time-demanding serial examinations and results of paraclinical data. In this waiting period, patients have to tolerate pain.Therefore, we aimed to study the hypothesis that relieving pain has no influence on valuable findings in physical examination. Methods: This double blind randomized clinical trial was carried out on 120 patients above 12 years old referred to an emergency department of a referral hospital with acute abdomen. Patients were divided into two groups of receiving intravenous placebo and Morphine randomly. Pain score, change in tenderness as well as change in rebound tenderness before and after receiving morphine or placebo were measured based on Numeric Pain Assessment Scale. Results: Statistically significant difference was observed between both groups regarding the mean pain score. Prevalence of tenderness and rebound tenderness after medication administration revealed a significant difference between two groups. Furthermore, pain and tenderness showed a significant decrease in patients receiving morphine also a significant difference occurred in rebound tenderness between two groups. Conclusion: Despite the fact that opioid analgesics decrease pain in patients with acute surgical abdomen, they do not tend to eliminate required diagnostic data being obtained from physical examination like tenderness and rebound tenderness. Surprisingly, all the acute abdomen cases had rebound tenderness after morphine administration. Therefore, this research advises a cautious usage of morphine in patients with acute abdomen.

    Full Text Available Retroperitoneal haemorrhage (or retroperitoneal haematoma refers to an accumulation of blood found in the retroperitoneal space. It is a rare clinical entity with variable aetiology including anticoagulation, ruptured aortic aneurysm, acute pancreatitis, malignancy, and bleeding from renal aneurysm. Diagnosis of retroperitoneal bleed is sometimes missed or delayed as presentation is often nonspecific. Multislice CT and arteriography are important for diagnosis. There is no consensus about the best management plan for patients with retroperitoneal haematoma. Stable patients can be managed with fluid resuscitation, correction of coagulopathy if any, and blood transfusion. Endovascular options involving selective intra-arterial embolisation or stent-grafts are clearly getting more and more popularity. Open repair is usually reserved for cases when there is failure of conservative or endovascular measures to control the bleeding or expertise is unavailable and in cases where the patient is unstable. Mortality of patients with retroperitoneal haematoma remains high if appropriate and timely measures are not taken. Haemorrhage from a benign renal tumour is a rarer entity which is described in this case report which emphasizes that physicians should have a wide index of suspicion when dealing with patients presenting with significant groin, flank, abdominal, or back pain, or haemodynamic instability of unclear cause. Our patient presented with features of acute abdomen and, being pregnant, was thought of having a ruptured ectopic pregnancy.

    Full Text Available Abstract Introduction Pneumoperitoneum is most commonly the result of a visceral perforation and usually presents with signs of acute peritonitis requiring an urgent surgical intervention. Non-surgical spontaneous pneumoperitoneum (not associated with a perforated viscus is an uncommon entity related to intrathoracic, intra-abdominal, gynecologic, iatrogenic and other miscellaneous causes, and is usually managed conservatively. Idiopathic spontaneous pneumoperitoneum is an even more rare condition from which both perforation of an intra-abdominal viscus and other known causes of free intraperitoneal gas have been excluded. Case presentation We present the case of an idiopathic spontaneous pneumoperitoneum. A 69-year-old Greek woman presented with acute abdominal pain, fever and vomiting. Diffuse abdominal tenderness on deep palpation without any other signs of peritonitis was found during physical examination, and laboratory investigations revealed leukocytosis and intraperitoneal air below the diaphragm bilaterally. Her medical history was unremarkable except for previous cholecystectomy and appendectomy. The patient did not take any medication, and she was not a smoker or an alcohol consumer. Emergency laparotomy was performed, but no identifiable cause was found. A remarkable improvement was noticed, and the patient was discharged on the seventh postoperative day, although the cause of pneumoperitoneum remained obscure. Conclusion A thorough history and physical examination combined with the appropriate laboratory tests and radiologic techniques are useful tools in identifying patients with non-surgical pneumoperitoneum and avoiding unnecessary operations.

    2016-01-01

    Full Text Available A 34-year-old woman with primary antiphospholipid syndrome was admitted to the Gastroenterology Department of our hospital with fever, acute abdomen, watery diarrhea, and extremely high levels of inflammatory parameters. She had a history of left lower limb deep vein thrombosis and pulmonary embolism and was taking warfarin potassium. Acute gastroenteritis was suspected and an antibiotic was administered, but symptoms progressed. Abdominal ultrasonography showed occlusion of the left hepatic vein and the middle hepatic vein and her D-dimer level was high. Accordingly, Budd-Chiari syndrome was diagnosed and high-dose intravenous infusion of heparin was initiated. Her abdominal symptoms improved and the levels of inflammatory parameters and D-dimer decreased rapidly. It is known that antiphospholipid syndrome can be complicated by Budd-Chiari syndrome that usually occurs as subacute or chronic onset, but acute onset is rare. It is difficult to diagnose acute Budd-Chiari syndrome complicating antiphospholipid syndrome and this complication generally has a poor outcome. However, the present case can get early diagnosis and successful treatment with tight anticoagulant therapy.

    Full Text Available Background. Inflammatory Fibroid Polyp (IFP of the colon is an exceedingly rare condition. Since 1952 till now only 32 cases have been reported worldwide of which only 5 were giant (>4 cm polyps mostly found in the caecum (15 cases with only 3 in the descending colon. Case Presentation. A 36-year-old female with no previous illness presented to the emergency unit with an acute onset pain over the right hypochondrium for 3 days associated with intermittent fever and anorexia. As she had evidence of localized peritonitis she underwent a diagnostic laparoscopy and subsequently an exploratory laparotomy. A mass measuring 8 × 7 × 5 cm arising from the hepatic flexure of colon was noted. Right hemicolectomy with ileotransverse anastomosis was performed. The mass was subsequently reported to be IFP. Conclusion. IFP is a very rare condition with clinical presentation depending upon its size and location. Definitive diagnosis is possible with histopathological examination of tissue aided by immunohistochemical studies. Surgical resection has been the most common method of treatment especially for large and giant colonic IFPs owing to challenges in terms of diagnosis and technical difficulties associated with endoscopic methods.

    Full Text Available Aim and Objective: The purpose of this study was to determine the spectrum of disease on abdominal ultrasound (US and the diagnostic efficacy of US in adult patients with nontraumatic acute abdomen at Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC, Ile-Ife. Materials and Methods: The study population included consecutive 150 adult patients aged 15 years and above presenting with nontraumatic acute abdomen via the adult emergency unit or as inpatients referred to the Radiology Department of OAUTHC, Ile-Ife for abdominal US. MINDRAY D.C-6 real-time US scanner with 3.5, 5.0, and 7.5 MHz probes and Doppler facilities were used to assess the intra-abdominal organs and the findings were compared with the clinical and surgical findings in those cases that were operated. Results: The common spectrum of diseases encountered on US in this study included appendicitis (66 [44%], ectopic pregnancy (34 [22%], intestinal obstruction (13 [8.7%] while the least finding was renal abscess 1 (0.7%. The correlation of US findings with surgical findings in this study showed sensitivity, specificity, and kappa agreement for appendicitis of 83.3%, 100.0%, and 0.808; ectopic pregnancy of 100.0%, 97.8%, and 0.958; acute cholecystitis of 100.0%, 100.0%, and 1.0. However, perforated viscus showed the least sensitivity (60.0%, specificity (99.2%, and kappa agreement 0.654. All the disease entities showed good kappa agreement beyond chance, and they were all statistically significant (P < 0.001. Conclusions: This study has shown a relatively high sensitivity, specificity and diagnostic accuracy of US in cases of nontraumatic acute abdomen in a careful hand. We, therefore, recommended that these advantages of US should be capitalized upon in settings where other advanced diagnostic modalities are not available.

    Health professionals often manage medical problems in critical situations under time pressure and on the basis of vague information. In recent years, dual process theory has provided a framework of cognitive processes to assist students in developing clinical reasoning skills critical especially in surgery due to the high workload and the elevated stress levels. However, clinical reasoning skills can be observed only indirectly and the corresponding constructs are difficult to measure in order to assess student performance. The script concordance test has been established in this field. A number of studies suggest that the test delivers a valid assessment of clinical reasoning. However, different scoring methods have been suggested. They reflect different interpretations of the underlying construct. In this work we want to shed light on the theoretical framework of script theory and give an idea of script concordance testing. We constructed a script concordance test in the clinical context of "acute abdomen" and compared previously proposed scores with regard to their validity. A test comprising 52 items in 18 clinical scenarios was developed, revised along the guidelines and administered to 56 4(th) and 5(th) year medical students at the end of a blended-learning seminar. We scored the answers using five different scoring methods (distance (2×), aggregate (2×), single best answer) and compared the scoring keys, the resulting final scores and Cronbach's α after normalization of the raw scores. All scores except the single best answers calculation achieved acceptable reliability scores (>= 0.75), as measured by Cronbach's α. Students were clearly distinguishable from the experts, whose results were set to a mean of 80 and SD of 5 by the normalization process. With the two aggregate scoring methods, the students' means values were between 62.5 (AGGPEN) and 63.9 (AGG) equivalent to about three expert SD below the experts' mean value (Cronbach's α : 0.76 (AGGPEN

We report the management of a septic Open Abdomen (OA patient by the help of negative pressure therapy (NPT and abdominal reapproximation anchor (ABRA system in pregnant woman with spontaneous jejunal perforation after emergent cesarean section (C/S with confounding factor of mild acute pancreatitis (AP. Presentation of Case. A 29-year-old and 34-week pregnant woman with AP underwent C/S. She was arrested after anesthesia induction and responded to cardiopulmonary resuscitation (CPR. There were only ash-colored serosanguinous fluid within abdomen during C/S. After C/S, she was transferred to intensive care unit (ICU with vasopressor support. On postoperative 1st day, she underwent reoperation due to fecal fluid coming near the drainage. Leakage point could not be identified exactly and operation had to be deliberately abbreviated due to hemodynamic instability. NPT was applied. Two days later source control was provided by conversion of enteroatmospheric fistula (EAF to jejunostomy. ABRA was added and OA was closed. No hernia developed at 10-month follow-up period. Conclusion. NPT application in septic OA patient may gain time to patient until adequate source control could be achieved. Using ABRA in conjunction with NPT increases the fascial closure rate in infected OA patient.

    Neonatal intestinal masses with spindle cell morphology have broad differential diagnoses and require a multidisciplinary approach to make the final diagnosis. Spindle cell masses with heterotopic cartilage in the gastrointestinal tract are very rare, and, to our knowledge, have not previously been reported in the neonate. Here we present a case of intestinal primitive spindle cell neoplasm with extensive heterotopic cartilage that manifested initially as acute abdomen in a 6-day-old term infant. Plain radiography demonstrated pneumoperitoneum, prompting diagnostic laparotomy that identified a perforated mass involving the midileum. Histologic and immunohistochemical examination demonstrated an infiltrative spindle cell tumor most compatible with infantile fibrosarcoma (IFS) by a process of exclusion, with nodules of mature heterotopic cartilage. Additional staging studies did not reveal any evidence of residual or metastatic disease. Recognition of this rare variant of IFS will aid in differentiation from other neonatal intestinal mesenchymal tumors.

    This study is intended to ascertain if outcome of acute abdominal surgery among elderly patients with acute abdominal pain have improved. Altogether 456 patients aged >65 years underwent emergency abdominal surgery between the years 2007 and 2009 in our hospital. After excluding emergency reoperations of elective surgery, a total of 430 consecutive patients were included in this retrospective audit. The key factors under analysis in this study were the occurrence of major complications and death from any cause within 30 days after the operation. In addition, we compared our results to our previously published data some 20 years ago. The most common diagnoses were cholecystitis (n = 139, 32.3 %, incidence of 125 per 100,000 elderly persons), incarcerated hernia (n = 60, 13.9 %, 54/100,000), malignancy related (n = 50, 11.6 %, 45/100,000), or acute appendicitis (n = 46, 10.7 %, 41/100,000). The majority of operations (80.7 %) were performed using open technique. Of all 112 laparoscopic procedures, 25.9 % were converted to open surgery. Reoperations were rare and postoperative surgical complications were not associated with statistically significant increase in mortality, even if reoperation was needed. The 30-day mortality and morbidity rates were 14.2 and 31.9 %, respectively. Logistic regression analysis showed that patient's age (p = 0.014), atrial fibrillation (p = 0.017), low body mass index (p = 0.001), open surgery (p = 0.029), ASA grade III or more (p abdominal surgery still have relatively high morbidity and mortality as reported in earlier studies.

  8. MDCT of the abdomen

    Multi-detector row computed tomography (MDCT) enables fast and thin acquisition of the abdominal anatomy. This allows multi-pass multi-planar studies that can be obtained during defined circulatory phases. When bolus timing is adequate, arterial phases with high contrast levels provide 'free lunch' CT angiographies eliminating the need for diagnostic angiographies in most cases. In addition to established clinical indications for abdominal CT such as preoperative MDCT of the liver or pancreas, MDCT of the abdomen is especially gaining ground in the work up for acute abdominal pain and abdominal trauma and is opening new indications for MDCT of the gastrointestinal tract. Indications for gastrointestinal MDCT include tumors, bleeding and ischemia of the small and large bowel as well as diverticulitis. The question of whether to use positive or negative contrast material for bowel distention for MDCT of the gastrointestinal tract is still a controversial issue. In selected cases, modifying the protocol to perform a 'CT enteroclysis' might improve sensitivity and specificity in depicting small bowel tumors or inflammatory changes such as in Crohn's disease. The most common gastrointestinal mesenchymal tumor is the gastrointestinal stromal tumor (GIST). MDCT may show hypervascular submucosal masses. Acute gastrointestinal (GI) bleeding is common with patients presenting with melena, hematemesis or hematochezia. In addition to the established initial work-up MDCT is beginning to establish itself for this indication. It may be especially helpful in the work up of obscure bleeding. Another relatively rare but important cause for acute abdominal pain is mesenteric ischemia. It may be caused by many conditions and may mimic various intestinal diseases. Bowel ischemia severity ranges from transient superficial changes of the intestinal mucosa to life-threatening transmural bowel wall necrosis. CT can demonstrate changes in ischemic bowel segments

    dyspnea, dehydration (++/4++, blood pressure= 70X40mmHg, anicteric, tense abdomen, diffusely painful, distended and hypertympanic, hydroaerial sounds absent. The thorax X-ray evidenced cardiac dextroversion, pneumoperitoneum bilaterally with gastric bubble on the right. Due to the general serious condition and confirmed diagnosis of acute abdomen perforation, a hydroelectrolytic vein replacement was held and the patient was submitted to an exploratory celiotomy, observing fecaloid diffuse peritonitis and perforation of sigmoid colon for foreign body taken away followed by mechanical cleaning, washing peritoneal cavity, Hartmann retossigmoidectomy, and bilateral drainage. CONCLUSION: Although a rare entity, the diagnosis of situs inversus totalis must be suspected in a physical examination and confirmed through image examinations, since the anatomic variations can disrupt the performance of clinical surgery.

    We report on a 54-year-old male patient with an aggressive T cell non-Hodgkin's lymphoma with abdominal manifestation undergoing autologous peripheral blood stem cell transplantation after high-dose chemotherapy in April 2003. About 4 months after transplantation, he developed severe upper abdominal pain. Ultrasound examination, X-ray, computed tomography of the abdomen and cardiac diagnostics could not explain the symptoms. While empiric therapy with high-dose acyclovir was started, we could document herpetic lesions in the gastric antrum by endoscopy. The epigastric pain rapidly decreased within several days after the start of acyclovir therapy. No herpetic skin lesions were observed at any time during the disease. This report demonstrates the importance of viral-induced gastritis in the differential diagnosis of severe abdominal pain in patients receiving autologous peripheral blood stem cell transplantation.

  17. Surgical Tips in Frozen Abdomen Management: Application of Coliseum Technique

    Directory of Open Access Journals (Sweden)

    Ioannis D. Kyriazanos

    2015-01-01

    Full Text Available Wound dehiscence is a serious postoperative complication, with an incidence of 0.5–3% after primary closure of a laparotomy incision, and represents an acute mechanical failure of wound healing. Relatively recently the concept of “intentional open abdomen” was described and both clinical entities share common pathophysiological and clinical pathways (“postoperative open abdominal wall”. Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as “frozen abdomen,” where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the “Coliseum technique” for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of “malignant” frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

  18. How to deal with an open abdomen?

    LENUS (Irish Health Repository)

    De Waele, Jan J

    2015-01-01

    Appropriate open abdomen treatment is one of the key elements in the management of patients who require decompressive laparotomy or in whom the abdomen is left open prophylactically. Apart from fluid control and protection from external injury, fluid evacuation and facilitation of early closure are now the goals of open abdomen treatment. Abdominal negative pressure therapy has emerged as the most appropriate method to reach these goals. Especially when combined with strategies that allow progressive approximation of the fascial edges, high closure rates can be obtained. Intra-abdominal pressure measurement can be used to guide the surgical strategy and continued attention to intra-abdominal hypertension is necessary. This paper reviews recent advances as well as identifying the remaining challenges in patients requiring open abdomen treatment. The new classification system of the open abdomen is an important tool to use when comparing the efficacy of different strategies, as well as different systems of temporary abdominal closure.

  19. [Anterolateral hernias of the abdomen].

    2007-01-01

    Anterolateral hernias of the abdomen group together umbilical, epigastric, and spigelian hernias and diastasis of the abdominal rectus. In spigelian hernias, 90% are located in the subumbilical region at the Monro line. They are asymptomatic in 90% of cases. The risk of strangulation is 10%-25% and requires surgical treatment. A herniorrhaphy is sufficient if the ring is less than 2 cm in diameter. Beyond 2 cm, open or celioscopic mesh repair is necessary. The risk of recurrence is less than 2%. Umbilical hernias result from progressive enlargement of the umbilical ring. The risk of strangulation is higher than 10%. The morbidity and mortality rate reaches 15% in large strangulated hernias. All umbilical hernias should therefore be treated surgically. If their diameter is under 2 cm, a simple herniorrhaphy can be done; otherwise mesh repair is required. In the cirrhosis patient, hernia treatment is part of the ascites treatment. The indication for surgery depends on liver function. Epigastric hernias are most often symptomatic: 80% have a ring smaller than 25 mm and 20% are multifocal. The risk of strangulation is low. If the ring is less than 20 mm, these hernias can be treated by herniorrhaphy. Recurrence is frequent - more than 10% - and always difficult to treat. Diastasis of the recti does not lead to complication, and treatment is not necessary. Cosmetic surgery can be used to manage diastasis.

    Abstract Background The infected abdomen poses substantial challenges to surgeons, and often, both temporary and definitive closure techniques are required. We reviewed the options available to close the abdominal wall defect encountered frequently during and after the management of complicated intra-abdominal infections. Methods A comprehensive review was performed of the techniques and literature on abdominal closure in the setting of intra-abdominal infection. Results Temporary abdominal closure options include the Wittmann Patch, Bogota bag, vacuum-assisted closure (VAC), the AbThera™ device, and synthetic or biologic mesh. Definitive reconstruction has been described with mesh, components separation, and autologous tissue transfer. Conclusion Reconstructing the infected abdomen, both temporarily and definitively, can be accomplished with various techniques, each of which is associated with unique advantages and disadvantages. Appropriate judgment is required to optimize surgical outcomes in these complex cases. PMID:23216525

  6. A CLINICAL STUDY ON BLUNT INJURY ABDOMEN

    Directory of Open Access Journals (Sweden)

    G. Kishore Babu

    2016-10-01

    Full Text Available BACKGROUND Abdominal trauma continues to account for a large number of trauma-related injuries and deaths. Motor vehicle accidents and urban violence, respectively, are the leading causes of blunt and penetrating trauma to this area of the body. Unnecessary deaths and complications can be minimized by improved resuscitation, evaluation and treatment. The new techniques and diagnostic tools available are important in the management of abdominal trauma. These improved methods, however, still depend on experience and clinical judgment for application and determination of the best care for the injured patient. The aim of the study is to 1. Analyse the incidence, clinical characteristics, diagnosis, indications for laparotomy, therapeutic methods and morbidity & mortality rates. 2. To study nature of blunt abdominal trauma. 3. To assess patient for surgical intervention and to avoid negative laparotomy. 4. To assess morbidity rate in different organs injury. 5. To evaluate modalities of treatment, complications and prognosis. MATERIALS AND METHODS This study is a prospective study on 97 patients with Blunt injuries to the abdomen admitted in S.V.R.R.G.G. Hospital, Tirupati during October 2013-15. Inclusion Criteria Patients > 13 years, with Blunt injury to abdomen either by RTA, fall, object contact, assault giving written informed consent. Exclusion Criteria Patients <13 yrs. Blunt injuries due to blasts, patients with severe cardiothoracic and head injuries who are hemodynamically unstable. CONCLUSION Blunt Trauma to abdomen is on rise due to excessive use of motor vehicles. It poses a therapeutic and diagnostic dilemma for the attending surgeon due to wide range of clinical manifestations ranging from no early physical findings to progression to shock. So, the Trauma surgeon should rely on his physical findings in association with use of modalities like x-ray abdomen, USG abdomen and abdominal paracentesis. Hollow viscus perforations are

    This article describes the different basic nonvascular interventional techniques in the abdomen that all general radiologists should be familiar with. It explains the indications and approaches for the different procedures (punctures, biopsies, drainage of collections, cholecystostomies, and nephrostomies). It also discusses the advantages and disadvantages of the different imaging techniques that can be used to guide these procedures (ultrasound, CT, and fluoroscopy) as well as the possible complications that can develop from each procedure. Finally, it shows the importance of following up patients clinically and of taking care of catheters. Copyright © 2016 SERAM. Published by Elsevier España, S.L.U. All rights reserved.

    Campbell, A M; Kuhn, W P; Barker, P

    2010-11-01

    We describe our experience of developing a modified vacuum-assisted closure (VAC) dressing for open abdomens. We see a high volume of trauma in our department. Massive delays in presentation of patients with acute abdomen are common. Closure at initial laparotomy is not possible in many cases, either because the patient has or will develop abdominal compartment syndrome, or because several re-look laparotomies will be required. A significant proportion of our patients who have undergone laparotomy therefore spend some of their stay in hospital with an open abdomen. The management of these patients is particularly labour intensive for nursing staff. The Opsite sandwich or Bogota bag invariably leaks, and sometimes needs changing daily. If a patient also has a temporary ileostomy, application can be difficult. The commercial VAC dressing is an improvement on the Opsite sandwich, but is prohibitively expensive. Financial constraints and the volume of abdominal trauma and sepsis we see mean that commercial VAC dressings for laparostomy are not affordable in our setting. We describe our adapted VAC dressing. It is inexpensive and easy to apply, has made a big difference in the nursing of patients with an open abdomen, and has enabled us to increase the rate of delayed primary closure (i.e., we have reduced the rate of ventral hernia). The modified VAC dressing is now our department's method of choice for temporary abdominal closure.

    Full Text Available Pyometra is the accumulation of pus in the uterine cavity, and spontaneous perforation of pyometra resulting in generalized diffuse peritonitis is extremely uncommon. We report a rare case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 66-year-old postmenopausal woman with diffuse abdominal pain and vomiting was admitted to our institution. She had a history of mixed connective-tissue disease and had been taking steroids for 20 years. Under a diagnosis of generalized peritonitis secondary to perforation of the gastrointestinal tract or uterus, supravaginal hysterectomy and bilateral salpingo-oophorectomy were performed. Unfortunately, wound dehiscence and infection occurred during the postoperative course, which were exacerbated by her immunocompromised state. Despite intensive care and a course of antibiotics, the patient died of multiple organ failure resulting from sepsis on the 36th postoperative day. Although correct diagnosis, early intervention, and proper treatment can reduce morbidity and mortality of spontaneous perforation of pyometra, if severe infection occurs, this disease can be life threatening for immunocompromised hosts.

    Full Text Available BACKGROUND Penetrating abdominal injuries forms an important component of surgical emergencies. It remains one of the commonest reasons for preventable deaths in any trauma systems. 1 Abdominal injuries may be parietal or visceral or perforating through and through injury. Unnecessary exploration leads to increased morbidity. The goal in managing penetrating abdominal injuries is to identify and treat all the damages caused by the weapon and to reduce negative laparotomy and avoid missed injuries. MATERIALS AND METHODS A retrospective study that was carried out in 53 patients in Government Kilpauk Medical College and Government Royapettah Hospital from May 2007 to July 2009 on penetrating injuries abdomen. RESULTS Among 53 patients, maximum number of cases were in the age group of 30-40 years. Assault injuries account for 87% of cases of penetrating abdominal injuries. Small bowel was the commonly injured organ in this study. Laparotomy was therapeutic in 94% of the cases (64% of the cases underwent laparotomy. CONCLUSION Careful and serial clinical examination and appropriate diagnostic investigations leads to successful treatment in these patients. Computed tomography is highly sensitive in predicting both peritoneal penetration and intra-abdominal visceral injuries.

She was initially diagnosed with ruptured ectopic pregnancy and ruptured corpus luteal cyst as the differential diagnosis. However she then, was finally diagnosed as acute hemorrhagic pancreatitis with spontaneous complete miscarriage. This is followed by review of literature on this topic. Acute pancreatitis in pregnancy is not uncommon. The emphasis on high index of suspicion of acute pancreatitis in women who presented with acute abdomen in pregnancy is highlighted. Early diagnosis and good supportive care by multidisciplinary team are crucial to ensure good maternal and fetal outcomes.

    Computed tomography (CT) scans usually include some disadvantages due to the nature of the imaging procedure, and these handicaps prevent accurate abdomen segmentation. Discontinuous abdomen edges, bed section of CT, patient information, closeness between the edges of the abdomen and CT, poor contrast, and a narrow histogram can be regarded as the most important handicaps that occur in abdominal CT scans. Currently, one or more handicaps can arise and prevent technicians obtaining abdomen images through simple segmentation techniques. In other words, CT scans can include the bed section of CT, a patient's diagnostic information, low-quality abdomen edges, low-level contrast, and narrow histogram, all in one scan. These phenomena constitute a challenge, and an efficient pipeline that is unaffected by handicaps is required. In addition, analysis such as segmentation, feature selection, and classification has meaning for a real-time diagnosis system in cases where the abdomen section is directly used with a specific size. A statistical pipeline is designed in this study that is unaffected by the handicaps mentioned above. Intensity-based approaches, morphological processes, and histogram-based procedures are utilized to design an efficient structure. Performance evaluation is realized in experiments on 58 CT images (16 training, 16 test, and 26 validation) that include the abdomen and one or more disadvantage(s). The first part of the data (16 training images) is used to detect the pipeline's optimum parameters, while the second and third parts are utilized to evaluate and to confirm the segmentation performance. The segmentation results are presented as the means of six performance metrics. Thus, the proposed method achieves remarkable average rates for training/test/validation of 98.95/99.36/99.57% (jaccard), 99.47/99.67/99.79% (dice), 100/99.91/99.91% (sensitivity), 98.47/99.23/99.85% (specificity), 99.38/99.63/99.87% (classification accuracy), and 98

    Diffusion-weighted magnetic resonance imaging (DW-MRI) provides qualitative and quantitative information of tissue cellularity and the integrity of cellular membranes. Since DW-MRI can be performed without ionizing radiation exposure and contrast media application, DW-MRI is a particularly attractive tool for patients with allergies for gadolinium-based contrast agents or renal failure. Recent technical developments have made DW-MRI a robust and feasible technique for abdominal imaging. DW-MRI provides information on the detection and characterization of focal liver lesions and can also visualize treatment effects and early changes in chronic liver disease. In addition DW-MRI is a promising tool for the detection of inflammatory changes in patients with Crohn's disease. (orig.) [German] Die diffusionsgewichtete (DW-)MRT ermoeglicht die Erfassung qualitativer und quantitativer Informationen bzgl. der Gewebezellularitaet und Membranintegritaet. Die DW-MRT ist insbesondere bei Patienten mit einer Allergie gegen gadoliniumhaltige Kontrastmittel oder eingeschraenkter Nierenfunktion attraktiv, da ihr Einsatz nicht mit Strahlenexposition oder Kontrastmittelgabe verbunden ist. Durch technische Weiterentwicklungen ist die robuste Anwendung der DW-MRI in der Bildgebung des Abdomens seit einiger Zeit moeglich geworden. In der Leberdiagnostik lassen sich Zusatzinformationen zur Detektion und Charakterisierung von Leberlaesionen gewinnen, aber auch Therapieerfolge dokumentieren und fruehe chronische Leberveraenderungen visualisieren. Neben ihrer Rolle bei hepatologischen und onkologischen Fragestellungen erscheint der Einsatz der DW-MRT zudem bei entzuendlichen Fragestellungen wie dem Morbus Crohn sehr viel versprechend. (orig.)

    The origin of abdominal pain may be extra-abdominal, caused by a thoracic illness. This article illustrates the various thoracic disorders that may present with acute abdominal pain. An erroneous focus on the abdomen alone can easily lead to misdiagnosis and incorrect treatment. In cases of unexplained acute abdominal pain, radiologists should be aware of also viewing beyond the borders of the abdomen. The key to most of these thoracic diagnoses is detection of pulmonary consolidation, pleural fluid or pericardial fluid. (orig.)

    Acute abdomen is a clinical diagnosis and not a definitive one. The use of ultrasound in management and diagnosis of acute abdomen is rarely invoked in our environment. The importance of definite diagnosis in surgical and medical management cannot be overemphasized To report a case of ultrasound diagnosis of retrocaecal appendicitis. A nine-year-old male child presented with vomiting, vague abdominal pain, diarrhoea, and fever, which led to the following differential diagnoses; acute food poison gastro-enteritis, typhoid enteritis, malaria and acute appendicitis. He was investigated along these lines. He had abdominal ultrasonography and CT scan . The ultrasound showed evidence of acute appendicitis. The findings on CT and surgery confirmed the diagnosis. Post-operatively, he made uneventful recovery. The use of ultrasound in acute abdomen is rarely invoked in our environment which may lead to unquantifiable consequences both in management and complications.

She was referred to our hospital at 42 weeks of gestation with breathlessness and oligohydramnios. She had worked in a glass and talc powder factory for 11 years and was diagnosed as having silicosis 2 years prior; she was on treatment. Following admission, she was evaluated for dyspnoea and underwent emergency Caesarean section for poor cervical dilation. She developed a burst abdomen on the third postoperative day with loops of gangrenous bowel protruding outside the abdomen. Emergency laparotomy with ileal resection and ileostomy was carried out. She was discharged on day 14 and is on follow-up. To the best of our knowledge, this is the first case of silicosis in pregnancy presenting with an unusual complication. 2015 BMJ Publishing Group Ltd.

    Butterfly's forward flight with periodic flapping motion is longitudinally unstable, and control of the thoracic pitching angle is essential to stabilize the flight. This study aims to comprehend roles which the abdominal motion play in the pitching stability of butterfly's flapping flight by using a two-dimensional model. The control of the thoracic pitching angle by the abdominal motion is an underactuated problem because of the limit on the abdominal angle. The control input of the thorax-abdomen joint torque is obtained by the hierarchical sliding mode control in this study. Numerical simulations reveal that the control by the abdominal motion provides short-term pitching stabilization in the butterfly's flight. Moreover, the control input due to a large thorax-abdomen joint torque can counteract a quite large perturbation, and can return the pitching attitude to the periodic trajectory with a short recovery time. These observations are consistent with biologists' view that living butterflies use their abdomens as rudders. On the other hand, the abdominal control mostly fails in long-term pitching stabilization, because it cannot directly alter the aerodynamic forces. The control for the long-term pitching stabilization will also be discussed.

    Currently, the open abdomen technique is the widely recognised method for treatment of life-threatening trauma, intra-abdominal sepsis, abdominal compartment syndrome and wound dehiscence. The techniques for temporary closure using negative pressure have gained increasing popularity. Although negative pressure wound therapy has been proved as an effective method in trauma, the results in diffuse peritonitis are contradictory. Overall, 108 patients with diffuse peritonitis and open abdomen were prospectively enrolled from January 2006 to December 2013--69 treated with mesh-foil laparostomy without negative pressure and 49 with vacuum-assisted closure (VAC(®)) The primary endpoints were the rate of primary fascial closure and mortality. The secondary outcomes were the rate of complications--enteroatmospheric fistulas, intra-abdominal abscesses, wound infection and necrotising fasciitis, intensive care unit (ICU) and overall hospital stay. VAC was associated with higher overall (73% vs 53%) and late primary fascial closure rates (31% vs 7%), lower rates of necrotising fasciitis (2% vs 15%, p=0.012), intra-abdominal abscesses (10% vs 20%), enteroatmospheric fistulas (8% vs 19%), overall mortality (31% vs 53%, pperitonitis. However, to a large extent, our results might be attributed to the combination of VAC with dynamic fascial closure. Published by the BMJ Publishing Group Limited.

    2011-01-01

    Variations in the venous architecture of the retro peritoneum is not uncommon, mostly those of Inferior Vena Cava (IVC). In this report we describe an extremely rare anatomical entity, where the IVC is formed by the union of the right common iliac vein and the left internal iliac vein. This is associated with a parallel venous channel which is the upward continuation of the left external iliac vein, which finally drains into the IVC at the level of renal veins. Awareness of such unusual variation of abdominal venous channels is helpful during retroperitoneal and laparoscopic surgeries of the abdomen, in staging of abdominal neoplasm, in radiological interpretation as well as therapeutic intervention in cases of recurrent pulmonary embolism.

    The subserous space is a large, anatomically continuous potential space that interconnects the chest, abdomen, and pelvis. The subserous space is formed from areolar and adipose tissue, and contains branches of the vascular, lymphatic, and nervous systems. As such, it provides one large continuous space in which many disease processes can spread between the chest, abdomen, and the pelvis.

    A resource allocation trade-off is expected when resources from a common pool are allocated to two or more traits. In holometabolous insects, resource allocation to different functions during metamorphosis relies completely on larval-derived resources. At adult eclosion, resource allocation to the abdomen at the expense of other body parts can be seen as a rough estimate of resource allocation to reproduction. Theory suggests geographic variation in resource allocation to the abdomen, but there are currently no empirical data on it. We measured resource allocation to the abdomen at adult eclosion in four geometrid moths along a latitudinal gradient. Resource (total dry material, carbon, nitrogen) allocation to the abdomen showed positive allometry with body size. We found geographic variation in resource allocation to the abdomen in each species, and this variation was independent of allometry in three species. Geographic variation in resource allocation to the abdomen was complex. Resource allocation to the abdomen was relatively high in partially bivoltine populations in two species, which fits theoretical predictions, but the overall support for theory is weak. This study indicates that the geographic variation in resource allocation to the abdomen is not an allometric consequence of geographic variation in resource acquisition (i.e., body size). Thus, there is a component of resource allocation that can evolve independently of resource acquisition. Our results also suggest that there may be intraspecific variation in the degree of capital versus income breeding.

    A part of damage-control laparotomy is to leave the fascial edges and the skin open to avoid abdominal compartment syndrome and allow further explorations. This condition, known as open abdomen (OA), although effective, is associated with severe complications. Our aim was to develop evidence-based recommendations to define indications for OA, techniques for temporary abdominal closure, management of enteric fistulas, and methods of definitive wall closure. The literature from 1990 to 2014 was systematically screened according to PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-analyses] protocol. Seventy-six articles were reviewed by a panel of experts to assign grade of recommendations (GoR) and level of evidence (LoE) using the GRADE [Grading of Recommendations Assessment, Development, and Evaluation] system, and an international consensus conference was held. OA in trauma is indicated at the end of damage-control laparotomy, in the presence of visceral swelling, for a second look in vascular injuries or gross contamination, in the case of abdominal wall loss, and if medical treatment of abdominal compartment syndrome has failed (GoR B, LoE II). Negative-pressure wound therapy is the recommended temporary abdominal closure technique to drain peritoneal fluid, improve nursing, and prevent fascial retraction (GoR B, LoE I). Lack of OA closure within 8 days (GoR C, LoE II), bowel injuries, high-volume replacement, and use of polypropylene mesh over the bowel (GoR C, LoE I) are risk factors for frozen abdomen and fistula formation. Negative-pressure wound therapy allows to isolate the fistula and protect the surrounding tissues from spillage until granulation (GoR C, LoE II). Correction of fistula is performed after 6 months to 12 months. Definitive closure of OA has to be obtained early (GoR C, LoE I) with direct suture, traction devices, component separation with or without mesh. Biologic meshes are an option for wall reinforcement if bacterial

  6. VALIDITY OF PARACENTESIS IN DIAGNOSING BLUNT TRAUMA ABDOMEN

    Full Text Available BACKGROUND Blunt abdominal trauma is a common case that comes to an emergency department and it is the most easily missed diagnosis resulting in catastrophic consequences. Delay in diagnosing a case is due to the nonspecific character of the symptoms with which it presents. Clinical signs that could be elicited in blunt trauma abdomen are equally nonspecific. Thus, to avoid delay and save the life of the patient, a doctor has to depend on various investigations to rule out blunt trauma abdomen. The modalities which help include paracentesis, diagnostic peritoneal lavage, Focused Abdominal Sonography for Trauma (FAST and ContrastEnhanced Computed Tomography (CECT. To choose the right investigation for the right patient helps in saving precious lives. Validity of each investigation, availability, condition of the patient are the main points to look into before deciding on the right investigative modality. Paracentesis is the simplest investigation that could be done in emergency department and also at the site of accident to triage the patient. Paracentesis has low sensitivity to detect blunt trauma. FAST is a better investigation with higher validity rates than paracentesis. This study aims to validate paracentesis, which is the simplest and commonest investigation used to identify blunt abdominal trauma. MATERIALS AND METHODS In this study, 106 patients who fulfilled the inclusion and exclusion criteria were followed up by detailed history, clinical examination, paracentesis and FAST to identify blunt abdominal trauma and then compared with a gold standard investigation, which was assigned as CECT for haemodynamically stable patients and laparotomy for haemodynamically unstable patients. Commonest organs injured in blunt trauma and their management was noted. Patients were followed up till discharge or death. Subsequently, the data were compiled using excel sheet and evaluated using tables and charts. RESULTS Paracentesis is found to have a

    Full Text Available Leukemic and lymphomatous infiltration of the appendix is a rare complication. We present the case of a 31-year-old male with acute promyelocytic leukemia who developed acute abdomen on day 11 of induction chemotherapy with idarubicin and cytarabine. After appropriate work-up, a clinical diagnosis of acute appendicitis was made. Despite severe pancytopenia, he successfully underwent laparoscopic appendectomy. The final pathology revealed leukemic infiltration of the appendix. It is hypothesized that the leukemic infiltration may play a role in the development of acute appendicitis. Further, this case demonstrates the need to maintain a high index of suspicion and prompt surgical intervention for surgical pathologies in neutropenic patients.

    Computed tomography (CT) scanning is recognised as a high-radiation dose modality and estimated to be 17 % of the radiological procedure and responsible for 70 % of medical radiation exposure. Although diagnostic X rays provide great benefits, their use involves some risk for developing cancer. The objectives of this study are to estimate radiation doses during chest, abdomen and pelvis CT. A total of 51 patients were examined for the evaluation of metastasis of a diagnosed primary tumour during 4 months. A calibrated CT machine from Siemens 64 slice was used. The mean age was 48.0 ± 18.6 y. The mean patient weight was 73.8 ± 16.1 kg. The mean dose-length product was 1493.8 ± 392.1 mGy cm, Volume CT dose index (CTDI vol) was 22.94 ± 5.64 mGy and the mean effective dose was 22.4 ± 5.9 mSv per procedure. The radiation dose per procedure was higher as compared with previous studies. Therefore, the optimisation of patient's radiation doses is required in order to reduce the radiation risk. © The Author 2015. Published by Oxford University Press. All rights reserved.

    2015-01-01

    Full Text Available Stereo feature matching is a technique that finds an optimal match in two images from the same entity in the three-dimensional world. The stereo correspondence problem is formulated as an optimization task where an energy function, which represents the constraints on the solution, is to be minimized. A novel intelligent biological network (Bio-Net, which involves the human B-T cells immune system into neural network, is proposed in this study in order to learn the robust relationship between the input feature points and the output matched points. A model from input-output data (left reference point-right target point is established. In the experiments, the abdomen reconstructions for different-shape mannequins are then performed by means of the proposed method. The final results are compared and analyzed, which demonstrate that the proposed approach greatly outperforms the single neural network and the conventional matching algorithm in precise. Particularly, as far as time cost and efficiency, the proposed method exhibits its significant promising and potential for improvement. Hence, it is entirely considered as an effective and feasible alternative option for stereo matching.

    Various measures of image quality were compared from adult abdomen scans obtained with a subsecond computed tomographic (CT) scanner (Imatron Ultrafast C-100) and a conventional third-generation whole-body scanner (GE9800). Forty images from 13 patients scanned within 2 hours of each other on both scanners were evaluated with techniques standardized as much as possible for CT exposure factors and contrast enhancement. Two observers in consensus evaluated matched anatomic levels using standard window width and level settings. Each image was graded on a scale of 1 (worst) to 5 (best) for spatial resolution, image noise, and presence and type of artifacts. Overall image quality also was graded. Averaged scores were compared between the two scanners. In all categories, scores were slightly higher for the GE9800. However, the differences in spatial resolution, presence of artifacts, overall image quality were not significant using the sign test. There was a significant difference, in favor of the GE9800, in image noise. The types of artifacts differed; the GE9800 produced more motion artifacts from bowel and surgical clips and the Imatron C-100 produced more rib shadow artifacts projecting on the liver and spleen. While the GE9800 produced abdominal images of slightly superior quality in adults, the Imatron Ultrafast C-100 was shown to produce images suitable for routine abdominal imaging in adults.

    To examine the methods and results of treatment in patients with an open abdomen (OA) at a single institution where an absorbable mesh closure (AMC) is most commonly used. A retrospective study was performed in OA patients from January 2001 to June 2007. Outcomes were analyzed in terms of enteroatmospheric fistula (EAF) formation and survival. There were 73 OA patients receiving definitive closures (40 trauma and 33 nontrauma). Twenty-four patients were able to undergo a delayed primary fascial closure (DPFC) after initial vacuum pack closure (DPFC rate 33%). The DPFC rate was significantly lower in patients with an associated infection or contamination (9% vs 44%, P = 0.002). The EAF and mortality rates of the DPFC group were 0% and 13%, respectively. Absorbable mesh closure was used in 41 of 49 patients who failed DPFC (84%). There were 9 patients who had EAF (overall EAF rate 12%), 6 of whom were in the AMC group (EAF rate 15%). The overall and AMC group mortality rates were 29% and 37%, respectively. Absorbable mesh closure carries high EAF and mortality rates. Therefore, DPFC should be considered as the primary closure method. Absorbable mesh closure should be reserved for patients who fail DPFC, especially those with peritonitis or contamination.

    Aim of the study: The influence of weight-adjusted current application in spiral CT of the abdomen on noise was investigated in a clinical study. Patients and methods: In 77 routine abdominal CT investigations (120 kV, 8 mm, pitch 1.5) the patients were divided into three body-weight groups A (<60 kg), B (60-80 kg), and C (>80 kg). The tube current was randomized prospectively in low weight group A, either 125 mA or 150 mA, in middle and high weight groups B and C, 150, 175 or 200 mA, with a tube revolution time of one second. The noise was measured in liver, skeleton muscle, fat tissue, and bladder content for evaluation of image quality. Results: The bodyweight groups differ significantly in noise, e.g., in the liver (150 mA): Group A: 15.8 HU, group B: 18.9 HU, group C: 21.5 HU. The increase of tube current (150, 175, 200 mA) within a body weight group resulted in a minor decrease of noise (18.9 HU, 17.6 HU, 17.5 HU, respectively, in group B). There is a good correlation of noise with body weight, body mass index and body cross section, but not with body size. Conclusion: A body weight adjusted reduction of tube current is possible without an increase of noise. (orig.)

    The purpose of this study was to develop a methodology to quantitatively measure the thorax-to-abdomen breathing ratio from a 4DCT dataset for breathing motion modeling and breathing motion studies. The thorax-to-abdomen breathing ratio was quantified by measuring the rate of cross-sectional volume increase throughout the thorax and abdomen as a function of tidal volume. Twenty-six 16-slice 4DCT patient datasets were acquired during quiet respiration using a protocol that acquired 25 ciné scans at each couch position. Fifteen datasets included data from the neck through the pelvis. Tidal volume, measured using a spirometer and abdominal pneumatic bellows, was used as breathing-cycle surrogates. The cross-sectional volume encompassed by the skin contour when compared for each CT slice against the tidal volume exhibited a nearly linear relationship. A robust iteratively reweighted least squares regression analysis was used to determine η(i), defined as the amount of cross-sectional volume expansion at each slice i per unit tidal volume. The sum Ση(i) throughout all slices was predicted to be the ratio of the geometric expansion of the lung and the tidal volume; 1.11. The Xiphoid process was selected as the boundary between the thorax and abdomen. The Xiphoid process slice was identified in a scan acquired at mid-inhalation. The imaging protocol had not originally been designed for purposes of measuring the thorax-to-abdomen breathing ratio so the scans did not extend to the anatomy with η(i) = 0. Extrapolation of η(i)-η(i) = 0 was used to include the entire breathing volume. The thorax and abdomen regions were individually analyzed to determine the thorax-to-abdomen breathing ratios. There were 11 image datasets that had been scanned only through the thorax. For these cases, the abdomen breathing component was equal to 1.11 - Ση(i) where the sum was taken throughout the thorax. The average Ση(i) for thorax and abdomen image datasets was found to be 1.20

    Introduction In general surgery, open abdomen treatment (OAT) is used to treat abdominal compartment syndrome (ACS) and sepsis, often after a primary surgical procedure associated with complications. The results achieved in this patient population may depend on factors that are yet unknown. This study evaluates independent patient-related prognostic factors after OAT. Methods 38 clinical parameters and survival data of 165 consecutive general surgery patients after OAT were entered into a prospective database according to a defined algorithm in order to analyse the underlying surgical pathology, predictors of survival and important aspects of OAT-related morbidity. Independent predictors of survival, OAT-related morbidity and duration of hospital stay were identified. Results Common indications for OAT were peritonitis, haemorrhage and ACS. Median age was 60 years and > 80 % of patients were ASA III/IV; median follow-up was 23 months. Oncologic surgery was performed in 19 % of cases. 30-day and 1-year mortality was 11 % and 34 %, respectively. Malignancy was a negative predictor (OR: 4.63, 95 % CI: 2.00-10.7) while mild obesity (BMI 25-35) and primary fascial closure, which was achieved in 82 % of patients, improved survival (OR: 0.2, 95 % CI: 0.07-0.55; OR: 0.19, 95 % CI: 0.06-0.57). Enteroatmospheric fistula (EAF) and giant hernia with impossible fascial closure were frequent after OAT (19 and 18 %), and malignancy was an independent risk factor for EAF (OR 3.47, CI [95 %]: 1.41-8.53). Vacuum-assisted wound closure or polyglactin mesh interposition did not affect EAF incidence. Conclusions General surgery patients after OAT differ significantly from trauma patients, and mortality as well as long-term morbidity is high. Outcome is greatly determined by independent patient-related factors after OAT. A tailored surgical approach based on objective evidence is needed to further improve the results after OAT.

    The goal after open abdomen treatment is to reach primary fascial closure. Modern negative pressure wound therapy systems are sometimes inefficient for this purpose. This retrospective chart analysis describes the use of the 'components separation' method in facilitating primary fascial closure after open abdomen. A total of 16 consecutive critically ill surgical patients treated with components separation during open abdomen management were analyzed. No patients were excluded. Primary fascial closure was achieved in 75% (12/16). Components separation was performed during ongoing open abdomen treatment in 7 patients and at the time of delayed primary fascial closure in 9 patients. Of the former, 3/7 (43%) patients reached primary fascial closure, whereas all 9 patients in the latter group had successful fascial closure without major complications (p = 0.019). Components separation is a useful method in contributing to successful primary fascial closure in patients treated for open abdomen. Best results were obtained when components separation was performed simultaneously with primary fascial closure at the end of the open abdomen treatment. © The Finnish Surgical Society 2015.

  20. Unusual side effect of cannabis use: acute abdomen due to duodenal perforation.

    2016-12-01

    The chronic use of synthetic cannabinoids (SCs) which has become an increasingly prevalent problem can rarely cause gastric and duodenal ulcer because of their effects on gastric secretion and emptying. Since peptic ulcer disease (PUD) is a rarely seen entity in patients who consult to the emergency service with complaints of abdominal pain, most of the physicians do not suspect of this clinical diagnosis. Perforation is a mortal complication of PUD, and early diagnosis and emergency surgery are life-saving procedures. A 16-year-old male patient was referred to our emergency service from another center with abdominal distension, complaints of abdominal pain, and bilious vomiting. His medical history revealed that he had been regularly using bonsai for the past 3 years. Plain abdominal radiograms of standing position revealed subdiaphragmatic free air, then we performed laparotomy which disclosed perforation of the first part of the duodenum. Surgical intervention with omental patch and primary closure (Graham patch) was successful. The patient who underwent nasogastric decompression and received antibiotherapy had not experienced any complication during the postoperative follow-up period. Herein, as an unusual manifestation, a patient who developed duodenal perforation following chronic SC use has been reported. In adolescent patients admitted with PUD or its complications to the emergency services, it is important to inquire for the use of addictive substances which are increasingly prevalent in order to determine the etiology.

    The purpose of this study was to sonographically evaluate the diagnosis of localized Castleman disease in the abdomen and pelvis. This was a retrospective analysis of 18 cases of Castleman disease localized in the abdomen and pelvis. The following features of the lesions were assessed on sonography (US): location, size, margin, echogenicity, echotexture, intralesional cystic necrosis, intralesional calcification, posterior acoustic enhancement, and blood supply. Of the 18 tumors, 16 were located in the abdomen and 2 were located in the pelvis close to iliac vessels. The most frequent appearance of localized Castleman disease in the abdomen and pelvis on US was of a single, well-defined, hypoechoic solid mass with no intralesional cystic necrosis. The internal echotexture was homogeneous in 4 cases and heterogeneous in 14 cases, with thin hyperechoic septa (n = 14) or calcifications (n = 3). Posterior acoustic enhancement was seen in 17 of the 18 cases (94%). Ninety-four percent of the lesions (17/18) had marked vascularity on color Doppler US. Localized Castleman disease in the abdomen and pelvis usually appears on US as a heterogeneously hypoechoic lesion containing thin septa, and more commonly than not, demonstrates posterior acoustic enhancement and marked vascularity. © 2014 Wiley Periodicals, Inc.

    In this study, we evaluate the dosimetry and image quality of computed tomography multislice abdomen protocols for different tube current modulation techniques (ATCM). We used the 16-slice Toshiba Activion CT scanner with the 'SureExposure3D' ATCM system. Thermoluminescent dosimeters were placed inside the anthropomorphic phantom Alderson-Rando for dosimetric assessments. An analytical phantom was used for the objective evaluation of image quality. It is observed that the higher standard deviation technique (SD) has the lowest value of effective dose. The use of different tube current modulation techniques showed significant reduction of radiation doses for the abdomen exams in computed tomography. The ATCM protocols can be an excellent alternative to dose reduction in CT scans, since it does not impair the diagnostic image quality. (author)

    2013-11-01

    The use of animals for testing and validating new medical devices and surgical techniques has raised ethical issues for a long time. Following the introduction of the Three Rs principle, significant efforts have been made to achieve a reduction in the numbers of animals used in testing. Nevertheless, the number of large animals used for testing purposes is still too high. This article describes a potential alternative to the use of large animals in the early phase of the development of surgical equipment -- a high-definition phantom pig abdomen. The phantom pig abdomen was developed from computed tomography scans by using affordable materials, and it was used with two different robotic platforms. It permitted the testing of minimally-invasive robotic pancreatic enucleation, with or without intraoperative ultrasound guidance. The phantom pig abdomen has proven to be a realistic tool, with the potential to reduce the cost and time-frame of the experiments. 2013 FRAME.

    Introduction The need for open abdomen in the treatment of severely ill neonates will increase in time as more complex abdominal procedures are undertaken. However, the experience of temporary closure of an open abdomen using vacuum-assisted closure (VAC) system is still relatively limited in premature and term neonates. The aim of this study is to describe and review our experience in the use of temporary VAC of the open abdomen for neonates with varying pathological processes. Materials and Methods A retrospective folder review of all neonates treated with VAC for open abdomen over the study period of 2010 to 2014 at our institution was performed. Results A total of 15 neonates were included in this study. Mean gestational age and postbirth age at VAC application were 33.6 ± 4.1 (28-40) weeks and 14 ± 10.2 (2-30) days, respectively. Mean weight at VAC application was 1,797.7 ± 730.8 (960-3,200) g. Initial diagnoses were necrotizing enterocolitis (seven), intestinal perforation (three), gastroschisis (two), congenital diaphragmatic hernia (two), and primary abdominal compartment syndrome (ACS) (one). Reasons for VAC application included confirmed ACS (2) and application to prevent ACS (13). Duration of VAC use was 4 ± 3.4 (0-13) days during which 2 ± 1.2 (1-5) applications were performed. Overall survival rate was 80% (12 of 15 patients). One patient with primary ACS died from sepsis with an open abdomen. The only potential VAC-related complication was an enterocutaneous fistula. Conclusion Temporary VAC of the open abdomen is a safe method of temporary abdominal closure to prevent ACS in high-risk postoperative conditions in neonates of any gestational age and birth weight.

    Three cases of acute intermittent porphyria are reported. While in first case severe pain in abdomen with intermittent exacerbation was the only presentation, the second patient presented as accelerated hypertension and acute abdominal crises in whom the clinical course was characterized by development of deep coma due to inappropriate secretion of antidiuretic hormone before she made complete recovery. The third patient, initially manifested as acute encephalitic syndrome. After initial improvement, she developed features of acute intermittent porphyria i.e. acute abdomen, neuropsychiatric symptoms, and rapidly progressing acute motor neuropathy leading to respiratory and bulbar paralysis. In addition, she developed severe and fluctuating dysautonomia leading to cardiac arrest and fatal termination. The importance of early diagnosis, recognition of autonomic disturbances, prompt treatment and counseling for avoidance of precipitating factors is stressed.

    To evaluate the efficacy of a simple and novel cardiopulmonary resuscitation (CPR) technique, nasopharyngeal oxygen with intermittent nose-close and abdomen-compression (NPO(2) -NC-AC) in an animal model. Prospective piglet study. In an animal physiology laboratory of a medical university. PIGLETS: Six healthy piglets <14 days old. Spontaneous breathing of the anesthetized piglets (n = 6) was medically ceased until severe bradycardia (<20 beat/min). NPO(2) -NC-AC CPR trial was then initiated by delivering NPO(2) at 1.0-1.5 L/kg/min and intermittently performing the NC-AC maneuver: (1) NC for inspiration, occluded nostrils for 1 sec; and (2) AC for expiration, released nostrils, and compressed the abdomen for 1 sec. NC-AC was repeated at a rate of 30/min for 5 min. This CPR trial was repeated three times in each piglet. Cardiopulmonary variables were monitored, recorded, and compared. A total of 18 CPR trials were performed. All of these acute life-threatening asphyxia events rapidly improved within 1 min of CPR. Cardiopulmonary variables recovered to the baseline levels and oxygenation continually increased. The intratracheal pressure (P(tr) ) values of positive end expiratory pressure and peak inspiratory pressure values were 4.3 ± 0.8 cmH(2) O and 26.2 ± 4.1 cmH(2) O, respectively. Chest wall movement was observed when the P(tr) reached 17.5 ± 3.1 cmH(2) O. All six piglets fully recovered after 63.8 ± 7.2 min of experiment without additional support. NPO(2) -NC-AC is a simple and effective CPR technique for severe acute cardiopulmonary asphyxia in piglets. It may be clinically applicable for supportive or rescue use.

    Differential diagnosis of acute abdomen in pregnant patients is one of the greatest challenges for the clinician. Occurrence of Familial Mediterranean Fever (FMF) paroxysm of peritonitis and acute cholecystitis during pregnancy is a unique clinical entity that leads to serious diagnostic and therapeutic dilemmas. We present the case of a 33-year-old Armenian patient at 16 weeks' gestational age with a history of FMF, who was admitted twice within 1 month with acute abdomen. The first episode was attributed to FMF and successfully treated conservatively with colchicine. The second episode was diagnosed as acute cholecystitis and led to emergent laparoscopic cholecystectomy and lysis of peritoneal adhesions from previous FMF attacks. The patient presented an uneventful postoperative clinical course and had a normal delivery of a healthy infant at the 39th week of gestation. Pregnant patients with acute abdomen should be evaluated with open mind. To the best of our knowledge, this is the first published report of the coexistence of 2 different causes of acute abdomen during pregnancy. Meticulous history and thorough physical, laboratory, and radiologic examination are the keys to reach a correct diagnosis. Treatment of pregnant patients with acute abdomen should be individualized. Administration of colchicine should be continued during conception, pregnancy, and lactation in patients with FMF history. Laparoscopic intervention in pregnant patients with surgical abdomen such as acute cholecystitis is the optimal method of treatment.

    The purpose of the study was to determine if abdomen/pelvis computed tomography (CT) can be safety omitted in the initial staging of a subgroup of children affected by Hodgkin Lymphoma (HL). Every participating center of A.I.E.O.P (Associazione Italiana di Ematologia ed Oncologia Pediatrica) sent local staging reports of 18F-fluorodeoxyglucose positron emission tomography (PET) and abdominal ultrasound (US) along with digital images of staging abdomen/pelvis CT to the investigation center where the CT scans were evaluated by an experienced pediatric radiologist. The local radiologist who performed the US was unaware of local CT and PET reports (both carried out after US), and the reviewer radiologist examining the CT images was unaware of local US, PET and CT reports. A new abdominal staging of 123 patients performed on the basis of local US report, local PET report, and centralized CT report was then compared to a simpler staging based on local US and PET. No additional lesion was discovered by CT in patients with abdomen/pelvis negativity in both US and PET or isolated spleen positivity in US (or US and PET), and so it seems that in the initial staging, abdomen/pelvis CT can be safety omitted in about 1/2 to 2/3 of children diagnosed with HL. © 2016 The Authors.

    Background: Vertebral fractures are commonly associated with osteoporosis and have significant morbidity and mortality rates. Osteoporotic vertebral fractures are presently considered as a treatable and preventable condition, and early detection is vital for further management. The evaluation of vertebral compression on multidetector computed tomography (MDCT) scans of the abdomen has, to our knowledge, not been reported before. Purpose: To assess the prevalence of vertebral collapse on routine abdominal CT scans, and to evaluate the usefulness of the multiplanar reconstruction (MPR) capability of MDCT scans in accurately identifying vertebral abnormalities such as vertebral collapse, spondylolisthesis, and retrolisthesis. Material and Methods: A retrospective review of 307 MDCT scans of the abdomen was carried out at a university teaching hospital. Identifiable patient information was anonymized for data protection. All images were reviewed on a picture archiving and communications system (PACS) using sagittal MPR and bone window for the assessment of the vertebrae. Data were collected from the Computerized Radiology Information System (CRIS). Results: Vertebral collapse was seen in 42 (13.6%) of the 307 patients undergoing routine MDCT of the abdomen. Multilevel and single-level collapses were seen in 24 and 18 patients, respectively. Spondylolisthesis was identified in 5.5% (n=17), and retrolisthesis was seen in 0.6% (n=2). All patients with vertebral fracture were older than 50 years. Women were more commonly affected than men. Conclusion: A significant number of patients with vertebral collapse were diagnosed using MPR on MDCT routine scans of the abdomen

    As part of the development of a noninvasive treatment for BPH using histotripsy, this study aimed to measure acoustic access for extracorporeal ablation of the prostate. Both transabdominal and transperineal approaches were considered. The objective was to measure the size and shape of a transducer aperture that could target the prostate without obstruction. CT images obtained from 17 subjects >56 years of age were used to create 3D reconstructions of the lower abdomen and pelvis. Target locations on the urethra at the base, mid, and apex in the prostate were marked along with a transrectal imaging probe. Evenly space rays spanning were traced from each target location towards the perineum and separately towards the abdomen with the maximum x-ray density encountered along each path recorded. The overall free aperture through the perineum was found to be a triangular shaped region bounded by the lower bones of the pelvis and the transrectal probe varying significantly in size between subjects. The free aperture through the abdomen was wedge shaped limited by the pubis also with great subject to subject variability. Average unblocked fractions of an f/1 transducer to target base, veru, and apex through the perineum were 77.0%, 94.4%, and 99.6%, respectively. Averages targeting through the abdomen were 86.1%, 52.3%, and 11.0%. Acoustic access to the prostate for through the perineum was judged to be feasible.

    Full Text Available Background. Failure to achieve delayed primary fascial closure (DPFC is one of the main complications of open abdomen (OA, certainly when abdominal sepsis is present. This retrospective cohort study aims to evaluate the effect of combined therapy of vacuum-assisted mesh-mediated fascial traction and topical instillation (VAWCM-instillation on DPFC in the open septic abdomen. Methods. The patients with abdominal sepsis who underwent OA using VAWCM were included and divided into the instillation and noninstillation (control groups. The DPFC rate and other outcomes were compared between the two groups. Results. Between 2007 and 2013, 73 patients with open septic abdomen were treated with VAWCM-instillation and 61 cases with VAWCM-only. The DPFC rate in the instillation group was significantly increased (63% versus 41%, P=0.011. The mortality with OA was similar (24.6% versus 23%, P=0.817 between the two groups. However, time to DPFC (P=0.003 and length of stay in hospital (P=0.022 of the survivals were significantly decreased in the instillation group. In addition, VAWCM-instillation (OR 1.453, 95% CI 1.222–4.927, P=0.011 was an independent influencing factor related to successful DPFC. Conclusions. VAWCM-instillation could improve the DPFC rate but could not decrease the mortality in the patients with open septic abdomen.

    Full Text Available Background : Damage control surgery and the open abdomen technique have been widely used in trauma. These techniques are now being utilized more often in non-trauma patients but the outcomes are not clear. We hypothesized that the use of the open abdomen technique in non-trauma patients 1 is more often due to peritonitis, 2 has a lower incidence of definitive fascial closure during the index hospitalization, and 3 has a higher fistula rate. Methods : Retrospective case series of patients treated with the open abdomen technique over a 5-year period at a level-I trauma center. Data was collected from the trauma registry, operating room (OR case log, and by chart review. The main outcome measures were number of operations, definitive fascial closure, fistula rate, complications, and length of stay. Results : One hundred and three patients were managed with an open abdomen over the 5-year period and we categorized them into three groups: elective (n = 31, urgent (n = 35, and trauma (n = 37. The majority of the patients were male (69%. Trauma patients were younger (39 vs 53 years; P < 0.05. The most common indications for the open abdomen technique were intraabdominal hypertension in the elective group (n = 18, severe intraabdominal infection in the urgent group (n=19, and damage control surgery in the trauma group (n = 28. The number of abdominal operations was similar (3.1−3.7 in the three groups, as was the duration of intensive care unit (ICU stay (average: 25−31 days. The definitive fascial closure rates during initial hospitalization were as follows: 63% in the elective group, 60% in the urgent group, and 54% in the trauma group. Intestinal fistula formation occurred in 16%, 17%, and 11%, respectively, in the three groups, with overall mortality rates of 35%, 31%, and 11%. Conclusion : Intra-abdominal infection was a common reason for use of the open abdomen technique in non-trauma patients. However, the definitive fascial closure and

    The technique factors and X-ray output from the X-ray units of three Nigerian hospitals were obtained and used to calculate doses delivered to patients during chest, abdomen, skull and neck examinations. DoseCal software was used to calculate the entrance skin dose (ESD) and effective dose (E) based on the values of technique factors employed. The result obtained for inter-hospital comparison showed wide variation of mean hospital ESD, from a factor of 1.3 for chest posteroanterior (PA) in hospital 2 (H2) to a factor of 63 for the same chest X-ray projection in hospital 1 (H1). A comparison of ESD obtained in this work with established reference doses in the United Kingdom (UK 2005 review), International Atomic Energy Agency (IAEA), Community of European Commission (CEC), Ghana and Sudan shows that the values of ESD obtained in H1 for five examinations; namely: chest (PA) and lateral (LAT), abdomen anteroposterior (AP) and skull (PA and LAT) are higher. In H2, the dose value for chest PA is about 50% higher than that of UK but comparable with CEC and less than IAEA and Ghanaian values. The dose values obtained in H3 chest PA are higher than UK, IAEA and CEC values but comparable with that of Ghana. For abdomen AP, the dose is a factor of 1.2 less than IAEA and CEC values but greater than the UK, Ghanaian and Sudanese values by a factor of 2.1, 1.2 and 4.5, respectively. Reference data for abdomen LAT and neck AP were not available for comparison. Higher effective doses are being delivered to patients in chest PA (H1 and H3) and abdomen AP (H1) when compared with the range of values reported in the literature. This trend is an indication that patients examined are at higher health risks.

    The use of ultrasound in veterinary medicine is widespread as a diagnostic supplement in the clinical routine of small animals, but there are few reports in wild animals. The objective of this study was to describe the anatomy, topography and abdominal sonographic features of coatis. The urinary bladder wall measured 0.11 ± 0.03 cm. The symmetrical kidneys were in the left and right cranial quadrant of the abdomen and the cortical, medullary and renal pelvis regions were recognized and in all sections. The medullary rim sign was visualized in the left kidney of two coatis. The liver had homogeneous texture and was in the cranial abdomen under the rib cage. The gallbladder, rounded and filled with anechoic content was visualized in all coatis, to the right of the midline. The spleen was identified in the left cranial abdomen following the greater curvature of the stomach. The parenchyma was homogeneous and hyperechogenic compared to the liver and kidney cortex. The stomach was in the cranial abdomen, limited cranially by the liver and caudo-laterally by the spleen. The left adrenal glands of five coatis were seen in the cranial pole of the left kidney showing hypoechogenic parenchyma without distinction of cortex and medulla. The pancreas was visualized in only two coatis. The left ovary (0.92 cm x 0.56 cm) was visualized on a single coati in the caudal pole of the kidney. The uterus, right adrenal, right ovary and intestines were not visualized. Ultrasound examination of the abdomen of coatis may be accomplished by following the recommendations for dogs and cats. It is possible to evaluate the anatomical and topographical relationships of the abdominal organs together with the knowledge of the peculiarities of parenchymal echogenicity and echotexture of the viscera.

    To evaluate the tolerability and maximum tolerated dose (MTD) of sorafenib administered concurrently with palliative radiotherapy. In patients with incurable cancer, sorafenib was escalated independently in three cohorts based on irradiation site: thorax, abdomen or pelvis. Sorafenib was administered days 1-28 and radiotherapy (30Gy in 10 fractions) was delivered days 8-12 and 15-19. Dose-limiting toxicities (DLT) were acute grade 3+ toxicities attributable to radiotherapy. For the thorax, abdomen and pelvis cohorts, 14, 16 and 4 patients were recruited, and Dose Levels 3, 3 and 2 were reached, respectively. Sorafenib-related systemic toxicity led to significant sorafenib interruption in 10 patients. There were 3 DLTs in total, one per cohort: grade 3 oesophagitis (thoracic), transaminase elevation (abdominal) and grade 5 bowel perforation (pelvic; patient with tumour invading bowel). Grade 2 radiation dermatitis developed in 12 patients. The trial was terminated early as slow accrual and sorafenib-related systemic toxicity prevented efficient evaluation of RT-related DLTs. The MTD of sorafenib when used with 30Gy in 10 fractions was not established due to sorafenib-related systemic toxicity. Severe radiotherapy-related toxicities were also observed. These events suggest this concurrent combination does not warrant further study. Copyright © 2017 Elsevier B.V. All rights reserved.

    This paper describes a method designed to model the repaired herniated human abdomen just after surgery and examine its static mechanical response to the maximum intra-abdominal pressure provoked by a physiological movement (standing cough). The model is based on the real geometry of the human abdomen bearing a large incisional hernia with several anatomical structures differentiated by MRI. To analyze the outcome of hernia repair, the surgical procedure was simulated by modeling a prosthesis placed over the hernia. Three surgical meshes with different mechanical properties were considered: an isotropic heavy-weight mesh (Surgipro®), a slightly anisotropic light-weight mesh (Optilene®), and a highly anisotropic medium-weight mesh (Infinit®). Our findings confirm that anisotropic implants need to be positioned such that the most compliant axis of the mesh coincides with the craneo-caudal direction of the body.

    The biogenic magnetic properties of the honeybee Apis mellifera were investigated with a view to understanding the bee's physiological response to magnetic fields. The magnetisations of bee abdomens on one hand, and heads and thoraxes on the other hand, were measured separately as functions of temperature and field. Both the antiferromagnetic responses of the ferrihydrite cores of the iron storage protein ferritin, and the ferrimagnetic responses of nanoscale magnetite (Fe{sub 3}O{sub 4}) particles, were observed. Relatively large magnetite particles (ca. 30 nm or more), capable of retaining a remanent magnetisation at room temperature, were found in the abdomens, but were absent in the heads and thoraxes. In both samples, more than 98% of the iron atoms were due to ferritin.

    Physical examination of the abdomen is an essential skill. Knowledge of its clinical anatomy and application is vital for making diagnoses. Misinterpretation of anatomy during examination can have serious consequences. This review addresses understanding of the anatomy, methodology, and complications of abdominal physical examination. It includes particular reference to modern technology and investigations. Physical examination is performed for diagnostic purposes. However, the art of physical examination is declining as more and more clinicians rely on newer technology. This can have regrettable consequences: negligence, waste of time and resources, and deterioration of clinical skills. With a sound knowledge of clinical anatomy, and realization of the importance of physical examination of the abdomen, clinician, and patients alike can benefit. Clin.

    This study evaluates the diagnostic accuracy of [F-18]-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) of the chest/upper abdomen compared to the generally performed scan from head to upper thighs, for staging and management of (suspected) lung cancer in patients with no history of malignancy or complaints outside the thorax. FDG-PET/CT scans of 1059 patients with suspected or recently proven lung cancer, with no history of malignancy or complaints outside the thorax, were analysed in a retrospective multi-centre trial. Suspect FDG-avid lesions in the chest and upper abdomen, the head and neck area above the shoulder line and in the abdomen and pelvis below the caudal tip of the liver were noted. The impact of lesions detected in the head and neck area and abdomen and pelvis on additional diagnostic procedures, staging and treatment decisions was evaluated. The head and neck area revealed additional suspect lesions in 7.2%, and the abdomen and pelvis in 15.8% of patients. Imaging of the head and neck area and the abdomen and pelvic area showed additional lesions in 19.5%, inducing additional diagnostic procedures in 7.8%. This resulted in discovery of additional lesions considered malignant in 10.7%, changing patient management for lung cancer in 1.2%. In (suspected) lung cancer, PET/CT limited to the chest and upper abdomen resulted in correct staging in 98.7% of patients, which led to the identical management as full field of view PET in 98.8% of patients. High value of FDG-PET/CT for staging and correct patient management is already achieved with chest and upper abdomen. Findings in head and neck area and abdomen and pelvis generally induce investigations with limited or no impact on staging and treatment of NSCLC, and can be interpreted accordingly.

    The lower abdominal obesity is more resistant to absorption as compared to that of upper abdomen. Differences in the physicochemical properties of the subcutaneous fat of the upper and lower abdomen may be responsible for this variation. There is paucity of the scientific literature on the physicochemical properties of the subcutaneous fat of abdomen. The present study was undertaken to create a database of physicochemical properties of abdominal subcutaneous fat. The samples of subcutaneous fat from upper and lower abdomen were collected from 40 fresh autopsied bodies (males 33, females 7). The samples were prepared for physicochemical analysis using organic and inorganic solvents. Various physicochemical properties of the fat samples analysed were surface tension, viscosity, specific gravity, specific conductivity, iodine value and thermal properties. Data was analysed by paired and independent sample t-tests. There was a statistically significant difference in all the physicochemical parameters between males and females except surface tension (organic) and surface tension (inorganic) of upper abdominal fat, and surface tension (organic) of lower abdominal fat. In males, viscosity of upper abdominal fat was more compared to that of lower abdomen (both organic and inorganic) unlike the specific conductivity that was higher for the lower abdominal fat as compared to that of the upper abdomen. In females there were statistically significant higher values of surface tension (inorganic) and specific gravity (organic) of the upper abdomen fat as compared to that of lower abdomen. The initial and final weight loss of the lower abdominal fat as indicated by Thermo Gravimetric Analysis was significantly more in males than in female. The difference in the physicochemical properties of subcutaneous fat between upper and lower abdomen and between males and females could be responsible for the variant behaviour of subcutaneous abdominal fat towards resorption.

    Whether for insects or for aircrafts, landing is one of the indispensable links in the verification of airworthiness safety. The mechanisms by which insects achieve a fast and stable landing remain unclear. An intriguing example is provided by honeybees (Apis mellifera ligustica), which use the swinging motion of their abdomen to dissipate residual flying energy and to achieve a smooth, stable, and quick landing. By using a high-speed camera, we observed that touchdown is initiated by honeybees extending their front legs or antennae and then landing softly on a wall. After touchdown, they swing the rest of their bodies until all flying energy is dissipated. We suggested a simplified model with mass-spring dampers for the body of the honeybee and revealed the mechanism of flying energy transfer and dissipation in detail. Results demonstrate that body translation and abdomen swinging help honeybees dissipate residual flying energy and orchestrate smooth landings. The initial kinetic energy of flying is transformed into the kinetic energy of the abdomen's rotary movement. Then, the kinetic energy of rotary movement is converted into thermal energy during the swinging cycle. This strategy provides more insight into the mechanism of insect flying, which further inspires better design on aerial vehicle with better landing performance.

    The aim of this study was to evaluate the manual compression of the abdomen (MCA) during expiration as a simple bedside method to detect expiratory flow limitation (EFL) during daily clinical practice of mechanical ventilation (MV). We studied 44 semirecumbent intubated and sedated critically ill patients. Flow-volume loops obtained during MCA were superimposed upon the preceding breaths and recorded with the ventilator. Expiratory flow limitation was expressed as percentage of expiratory tidal volume without any increase in flow during MCA (MCA [%V(T)]). In the first 13 patients, MCA was validated by comparison with the negative expiratory pressure (NEP) technique. Esophageal pressure changes during MCA and intrinsic positive end-expiratory pressure were also recorded in all the patients. Manual compression of the abdomen and NEP agreed in all cases in detecting EFL with a bias of -0.16%. Percentage of expiratory tidal volume without any increase in flow during MCA is highly correlated with percentage of expiratory tidal volume without any increase in flow during NEP (n = 13, P respiratory disease. Manual compression of the abdomen provides a simple, rapid, and safe bedside reliable maneuver to detect and quantify EFL during mechanical ventilation. Copyright © 2012 Elsevier Inc.

Therefore, the threat of viral outbreaks in wild and cultured shrimp via frozen commodity shrimp exists. Because frozen shrimp are imported with and without the cephalothorax, more knowledge is needed concerning the infectivity of a cephalothorax relative to that of an abdomen. We compared the mortality rates from shrimp exposed to a WSSV-infected cephalothorax, abdomen, or whole shrimp cadaver. Estimates of transmission coefficients from the exposures to the infected cephalothorax, abdomen, or whole shrimp were also calculated because the transmission coefficients account for differences in the initial doses. In addition, we compared the variability in infectivity of pieces of shrimp by feeding 24 equal-sized pieces of cephalothorax and abdomen to 24 individually isolated shrimp. In Expt 1, susceptible shrimp did not completely consume the infected abdomen, and a significant difference was detected among shrimp exposed to the abdomen (mortality rate = 0.40), cephalothorax (mortality rate = 0.75), and whole shrimp cadaver (mortality rate = 0.67). The calculated transmission coefficients were 0.95 from an infected cephalothorax, 0.59 from an infected abdomen, and 0.69 from an infected whole shrimp cadaver. In Expt 2, susceptible shrimp were starved to ensure complete ingestion of each dose. No significant difference was observed in the estimated mortality rates from an infected cephalothorax (0.58), abdomen (0.63), or whole shrimp (0.67). The calculated transmission coefficients were 0.84 from an infected cephalothorax, 0.83 from an infected abdomen, and 0.60 from an infected whole shrimp cadaver. In Expt 3, no difference was observed in the mortality rates resulting from exposures to pieces of infected cephalothorax (0.57) or abdomen (0.58). Our results suggested that there was no difference in the viral loads of a WSSV-infected cephalothorax or abdomen, but

    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.

    Acute vascular occlusion within the mesenteric circulation leads to ischemic damage of the corresponding bowel segment, which starts on the mucosal level and progresses transmurally. Report on pathogenesis, clinical picture and treatment of various forms of intestinal ischemia. Analysis of the available literature taking into consideration our own experience. Frequently, predisposing diseases and risk factors are present (e.g., cardiac diseases, hypercoagulability, status post cardiac surgery, circulatory failure, or administration of vasoconstrictive drugs). Acute small bowel ischemia-caused by either mesenteric embolism, mesenteric artery thrombosis, nonocclusive mesenteric ischemia (NOMI) or mesenteric venous thrombosis-represents an acute emergency. If this condition is suspected clinically, the diagnosis must be established immediately by computed tomography of the abdomen with intravenous administration of contrast medium in order to prevent irreversible damage to the small bowel. Medical treatment is supportive. If possible, occluded vessels may be re-opened either by radiologic intervention or surgically. Irreversibly damaged bowel segments must be surgically removed. Ischemic colitis has a benign course in most cases if limited to reversible mucosal damage. The diagnosis is based mainly on colonoscopy and computed tomography findings, and treatment is symptom oriented. Rarely, severe manifestations with a worse prognosis due to considerable comorbidities occur. In such cases, surgical removal of the ischemic bowel is frequently required. Even today, acute mesenteric ischemia is associated with a poor prognosis. To improve survival and to reduce long-term morbidity, a rapid and systematic diagnostic workup is mandatory.

    Full Text Available Acute appendicitis of amebic origin is considered a rare cause of acute appendicitis. We report a case of amebic appendicitis presenting with fever, severe pain in the right lower quadrant of the abdomen and rebound tenderness. Lab investigations revealed neutrophilic leukocytosis. The patient underwent appendectomy. Histopathological examination revealed numerous Entameba histolytica trophozoites in the mucosa of the appendix. Acute appendicitis of amebic origin does not appear frequently. Appendicular amebiasis can give the clinical features of acute appendicitis and should be treated accordingly.

    Objective: The goal of this report is to examine the success of vacuum-assisted fascial closure (VAFC) under a carefully applied protocol in abdominal closure after open abdomen. Summary Background Data: With the development of damage control techniques and the understanding of abdominal compartment syndrome, the open abdomen has become commonplace in trauma patients. If the abdomen is not closed in the early postoperative period, the combination of adhesions and fascial retraction frequently make primary fascial closure impossible and creation of a planned ventral hernia is required. We have previously reported our experience with the development of a technique for VAFC that allowed for closure of the fascia in many such patients long after initial operation. During this previous study, during which the technique was being developed, VAFC was successful in 69% of patients in whom it was applied, and 22 patients were successfully closed at ≥ 9 days after initial surgery (range, 9 to 49 days). A protocol for the use of VAFC in patients with open abdomen was developed on the basis of these data and has been employed since October 2001. The outcome of this protocol's use is examined. Methods: This is a prospective evaluation of all trauma patients admitted to Wake Forest University Baptist Medical Center over a 19-month period who required management with an open abdomen. VAFC employs suction applied to a large polyurethane sponge under an occlusive dressing in the wound and allows for constant medial traction of the abdominal fascia. It is attempted in all patients in whom the rectus muscles and fascia are intact. Studied variables include fascial closure rate, time to closure, incidence of wound dehiscence, and hernia development after closure. Results: From November 1, 2001, through May 31, 2003, 212 laparotomies were performed in injured patients; 53 (25%) of these patients required open abdomen management. Mean injury severity score for the group was 34, with

    Vascular structures in the abdomen can compress or be compressed by adjacent structures. Classic imaging findings of vascular compressions, including median arcuate ligament syndrome, superior mesenteric artery syndrome, nutcracker syndrome, portal biliopathy, May-Thurner syndrome, and ureteropelvic junction obstruction will be discussed here. It is important to correlate imaging findings and clinical data to identify asymptomatic vascular compression which requires no treatment, intermittent vascular compression with nonspecific or vague clinical manifestation, and the subset of patients with true syndromes who will benefit from treatment.

    The recently developed MAX (Male Adult voXel) and the FAXht (Female Adult voXel) head and trunk phantoms have been used to calculate organ and tissue equivalent dose conversion coefficients for X-ray radiographs of the chest and the abdomen as a function of source and field parameters, like voltage, filtration, field size, focus-to-skin distance, etc. Based on the equivalent doses to twenty three organs and tissues at risk, the effective dose has been determined and compared with corresponding data for others phantoms. The influence of different radiation transport codes, different tissue compositions and different human anatomies have been investigated separately. (Author)

    Peculiar features of surgical treatment of gunshot, non-lethal arm, and cold steel wounds are formulated based on the 20-year experience with managing 20,000 injured subjects having multiple and combined injuries to neck, chest, and abdomen of suicidal and criminal character. The growth in the number of patients with suicidal wounds and hemocontact viral infections (hepatitis, HIV) is emphasized. It is concluded that assessment of the state of gas exchange, lipid peroxidation, antioxidative, and immune systems does not give full idea of pathogenetic mechanisms of traumatic diseases.

    other levels of the system. Acute surgical abdomen is a health problem to be faced immediately to avoid complications, even fatal, in our patients. A pedagogic method for acquiring with quality the necessary knowledge and orienting the correct behaviour to each patient is the method of invariants. The concept of Invariant covers the identification of essential and necessary questions to arrive at a diagnosis. When the Comprehensive General Physician knows the invariants of an entity, then he/she can take decisions with a high margin of safety. An Acute Surgical Abdomen may be caused by hundreds of diseases, therefore, it will be impossible to study them, one by one. Since this is a serious entity, any mistake made in managing this disease can be fatal. We have identified seven (7 Invariant signs in Acute Surgical Abdomen, which can be recognized in 9 out of 10 patients that go to the doctor’s with acute abdominal pain. There are difficulties due to the identification of these signs just in a small number of patients to whom we call "Special Situations"

Among all cases of acute renal failure, the incidence of renal cortical necrosis was 3.8% in one of the study in North India. Till date, only eight cases of bilateral cortical necrosis following acute pancreatitis were reported in the literature. We report a case of a 27-year-old male patient with abdominal pain, nausea and vomiting since 2 days duration and anuria since 24 h. Serum amylase and lipase were raised, and elevated serum creatinine was noted on admission. Contrast-enhanced computed tomography scan of the abdomen revealed changes of acute pancreatitis with hypoenhancement of renal cortex compared to medulla on both sides (reverse rim sign-stronger enhancement of the renal medulla compared to cortex, suggest an acute renal cortical necrosis.

    Full Text Available We report a case of acute appendagitis in a patient who presented initially with typical features of acute appendicitis. The diagnosis of acute appendagitis was made on pathognomonic signs on computed tomography (CT scan. Abdominal pain is a common surgical emergency. CT is not always done if there are clear features of acute appendicitis. The rare but important differential diagnosis of acute appendagitis must be borne in mind when dealing with patients with suspected acute appendicitis. A CT scan of the abdomen may avoid unnecessary surgery in these patients.

    To evaluate diagnostic accuracy of a noise-optimized virtual monoenergetic imaging (VMI+) reconstruction technique for detection of active arterial abdominal bleeding on dual-energy (DE) CT angiography compared with standard image reconstruction. DE CT angiography data sets of 71 patients (46 men; age 63.6 y ± 13.3) with suspected arterial bleeding of the abdomen or pelvis were reconstructed with standard linearly blended (F_0.5), VMI+, and traditional virtual monoenergetic imaging (VMI) algorithms in 10-keV increments from 40 to 100 keV. Attenuation measurements were performed in the descending aorta, area of hemorrhage, and feeding artery to calculate contrast-to-noise ratios (CNRs) in patients with active arterial bleeding. Based on quantitative image quality results, the best series for each reconstruction technique were chosen to analyze the diagnostic performance of 3 blinded radiologists. DE CT angiography showed acute arterial bleeding in 36 patients. Mean CNR was superior in 40-keV VMI+ compared with VMI series (all P < .001), which showed highest CNRs in 70-keV VMI and F_0.5 (21.6 ± 7.9, 12.9 ± 4.7, and 10.4 ± 3.6) images. Area under the curve analysis for detection of arterial bleeding showed significantly superior (P < .001) results for 40-keV VMI+ (0.963) compared with 70-keV VMI (0.775) and F_0.5 (0.817) series. Diagnostic accuracy in patients with active arterial bleeding of the abdomen can be significantly improved using VMI+ reconstructions at 40 keV compared with standard linearly blended and traditional VMI series in DE CT angiography.

    Full Text Available Acute gastric dilatation can have multiple etiologies which may lead to ischemia of the stomach. Without proper timely diagnosis and treatment, potentially fatal events such as gastric perforation, haemorrhage, and other serious complications can occur. Here we present a 36-year-old man who came to the casualty with pain abdomen and distension for 2 days. Clinically, abdomen was asymmetrically distended more in the left hypochondrium and epigastrium region. Straight X-ray abdomen showed opacified left hypochondrium with nonspecific gaseous distension of bowel. Exploratory laparotomy revealed dilated stomach with patchy gangrene over lesser curvature and fundic area. About 4 litres of brownish fluid along with semisolid undigested food particles was sucked out (mainly undigested pieces of meat. Limited resection of gangrenous areas and primary repair were done along with feeding jejunostomy. Necrosis of the stomach was confirmed on histopathology. The patient recovered well and was discharged on the tenth postoperative day.

    Full Text Available Abstract Background Penetrating injuries of the abdomen and spinal canal that involve organic material of animal origin are extremely rare and derive from domestic and wild animal attacks or fish attacks. Case presentation In this case report we present the unique, as far as the literature is concerned, unprovoked woman's injury to the abdomen by a swordfish. There are only four cases of swordfish attacks on humans in the literature - one resulted to thoracic trauma, two to head trauma and one to knee trauma, one of which was fatal - none of which were unprovoked. Three victims were professional or amateur fishermen whereas in the last reported case the victim was a bather as in our case. Our case is the only case where organic debris of animal's origin remained in the spinal canal after penetrating trauma. Conclusions Although much has been written about the management of penetrating abdominal and spinal cord trauma, controversy remains about the optimal management. Moreover, there is little experience in the management of patients with such spinal injuries, due to the fact that such cases are extremely rare. In this report we focus on the patient's treatment with regard to abdominal and spinal trauma and present a review of the literature.

    Full Text Available Background. Peritoneal carcinomatosis (PC is associated with a poor prognosis. Cytoreductive surgery (CRS and HIPEC play an important role in well-selected patients with PC. The aim of the study is to present the differences in the intraoperative parameters in patients who received HIPEC in two different manners, open versus closed abdomen. Patients and Methods. The population includes 105 patients with peritoneal carcinomatosis from colorectal, gastric, and ovarian cancer, sarcoma, mesothelioma, and pseudomyxoma peritonei. Group A (n=60 received HIPEC using the open technique and Group B (n=45 received HIPEC with the closed technique. The main end points were morbidity, mortality, and overall hospital stay. Results. There were two postoperative deaths (3.3% in the open group versus no deaths in the closed group. Twenty-two patients in the open group (55% had grade III-IV complications versus 18 patients in the closed group (40%. There are more stable intraoperative conditions in the closed abdomen HIPEC in CVP, pulse rate, and systolic pressure parameters. Conclusions. Both methods are equal in the HIPEC procedures. Perhaps the closed method is the method of choice for frail patients due to more stable hemodynamic parameters.

    The authors have carried out an experimental study on the reaction of an animal's organism to the presence of an open copper intra-uterine device when placed in the abdomen. The study was carried out on two groups each of 10 rabbits and two bitches. The intra-uterine device was placed in the pouch of Douglas by laparotomy, directly in one group and after contamination with genital secretions in the other. The state of the animals was checked six weeks after the initial laparotomy. Trauma caused by the operation was minimal because there were no adhesions found on the parietal peritoneum. On the other hand in experimental conditions that are very similar to those found when an intra-uterine device goes through the uterus in a human subject and involves contamination with genital secretions, in 50 per cent of cases the intra-uterine device migrated within the abdominal cavity. It was picked up by the omentum and this underwent such a strong fibrous reaction that it brought about multiple intestinal adhesions. Though the authors admit that experimental results in animals cannot be extrapolated to women, they believe that these results should be taken into consideration and that it would be imprudent to leave an intra-uterine device in the abdomen in a woman when there is proof that it has migrated, because there would then be a major risk of intestinal obstruction due to an adhesion that as formed a band.

    The aim of this work was to reduce the influence of motion on diffusion-weighted MR images of the abdomen by pulse triggering of single-shot sequences. Five healthy volunteers were examined both without and with finger pulse-triggering of a diffusion-weighted single-shot echo planar MR imaging sequence at 1.5 T. Series of diffusion-weighted images were acquired at different phases of the cardiac cycle by varying the time delay between finger pulse and sequence acquisition. The measurements were repeated three times. The diffusion weighted images were analysed by measuring the signal intensities and by determining the ADC values within the spleen, kidney and liver. The magnitude of motion artifacts on diffusion weighted images shows a strong dependence on the trigger delay. The optimum trigger delay is found to be between 500 and 600 ms. For these values the abdominal organs appear homogeneous on all diffusion weighted images and the strongest signal intensities are detected. At optimum triggering the accuracy of the apparent diffusion coefficients is up to 10 times better than without triggering. Moreover, the standard deviation of the repeated measurements is smaller than 12% for all volunteers and for all organs. Without triggering the standard deviation is larger by a factor of 4 on average. Pulse triggering of single-shot sequences leads to significant reduction of motion related artifacts on diffusion weighted images of the abdomen and provides more accurate and reproducible ADC values.

  1. Closed hyperthermic intraperitoneal chemotherapy with open abdomen: a novel technique to reduce exposure of the surgical team to chemotherapy drugs

    Exposure of the surgical team to toxic drugs during hyperthermic intraperitoneal chemotherapy (HIPEC) remains a matter of great concern. In closed-abdomen HIPEC operating room staffs are not exposed to drugs, but the distribution of the heated liquid within the abdomen is not optimal. In open-abdomen HIPEC, the opposite is true. Even though the open-abdomen method is potentially more effective, it has not become a standard procedure because of the risk of exposure of members of the team to drugs. We present a new technique (closed HIPEC with open abdomen) which ensures protection against potentially contaminating exposure to liquids, vapours and aerosols, and allows permanent access to the whole abdominal cavity. Its principle is to extend the abdominal surgical wound upwards with a sort of “glove-box”. The cutaneous edges of the laparotomy are stapled to a latex «wall expander». The expander is draped over a special L-section metal frame placed above the abdomen. A transparent cover containing a « hand-access » port like those used in laparoscopic surgery is fixed inside the frame. In 10 patients, this device proved to be hermetic both for liquids and vapours. Intra-abdominal temperature was maintained between 42 and 43°C during most of the procedure. The whole abdominal cavity was accessible to the surgeon allowing optimal exposure of all peritoneal surfaces. This technique allows optimal HIPEC while limiting the potential toxic effects for the surgical, medical and paramedical teams. PMID:17929098

    Full Text Available Abstract Solitary caecal diverticulum is an uncommon entity and therefore difficult to diagnose except at surgery. Caecal diverticulitis is an infrequent cause of acute abdomen and usually presents in a manner similar to acute appendicitis. It is extremely difficult to differentiate it preoperative from acute appendicitis and such distinction is usually made in the operating room. The optimal management of this clinical condition is still controversial, ranging from conservative treatment with antibiotics to aggressive surgical resections. We report a case of a 61 year old Caucasian who presented with acute onset right iliac fossa pain indistinguishable from acute appendicitis. The true diagnosis of a perforated acute caecal diverticulitis with an abscess mass was only made at operation in the presence of a macroscopically normal appendix. We reviewed the literature to highlight the difficulty of a preoperative diagnosis and the need for a high index of suspicion especially in the older age group presenting in manner similar to acute appendicitis.

    Non-contrast chest CT scans are commonly performed while CT scans of the abdomen and pelvis are performed in a select subset of patients; those with limited renal function, an allergy to iodinated contrast, in the setting of suspected renal calculus, retroperitoneal hematoma, common duct calculus, abdominal aortic aneurysm with or without rupture, and in patients undergoing a PET-CT scan. In the absence of intravenous contrast, vascular structures may prove challenging to evaluate, yet their assessment is an important component of every non-contrast CT examination. We describe the key imaging features of both arterial and venous pathology, and review clues and common associated non-vascular findings, which can help the radiologist identify vascular disorders at non-contrast CT. Briefly, alternative imaging options are discussed.

    Human Blastocystis hominis were isolated from diarrhea patients' feces and cultured in vitro. Then the cultures were inoculated intraperitoneally to laboratory mice. The B. hominis in living mice were collected and inoculated again to healthy mice. The B. hominis showed dose-dependent pathogenicity in the primary inoculation. No pathogenicity was observed in the secondary inoculation. The protozoan existed in the living mice abdomen cavity for more than 6 months and the cyst was the only form. These results showed that encystation enable the parasite to avoid the immune attack in competent host and simultaneously decrease the pathogenicity to host. Intraperitoneal inoculation to laboratory mice is a good method to maintain and propagate B. hominis. This is also a good model to study the interaction of B. hominis and immune system.

    A suspected case of localized visceral hyperpigmentation was described for a breed of broiler in China. Using optical microscopy, the accumulation of pigments in the abdominal skin and visceral peritoneum was observed. Electron microscopy was used to further study the ultrastructure of the pigmented peritoneum, and pigment granules resembling melanosomes at different stages were found, and melanocytes were present in this tissue. Infrared spectroscopy was used to analyze the physical-chemical properties of pigments extracted from these broilers. Using synthetic melanin as a reference and the melanin from the peritoneum of Silkie fowls as a control, the pigments in the peritonea of these broilers were found to be melanin, and it had a chemical structure similar to that of melanin from the Silkie fowl peritoneum. In this way, the black abdomens of these broilers were found to have been caused by accumulation of melanin produced by melanocytes in visceral peritonea.

    Full Text Available Background: Patients with Sickle cell trait (SCT are usually asymptomatic. They are usually unaware of their condition unless they have a family history. There are specific situations, where these people suffer from the effects of sickle cell trait. Splenic syndrome at high altitude is one of the specific problems. It is usually seen after a patient with SCT has been inducted to high altitude like in case of mountaineers and military personnel deployed in high altitude warfare. Pain abdomen due to splenic infarction in individuals with SCT is one of the manifestations. These patients, if diagnosed in time, they can be spared from unnecessary surgical interventions. We present herewith our experience of splenic infarction due to SCT in high altitude and their management.

    2015-08-01

    Conclusion: Ovarian hyperstimulation during IVF–embryo transfer treatment is a risk factor for developing adnexal torsion. Early diagnosis and prompt surgical intervention is the only way to protect the ovary and preserve the pregnancy. Laparoscopic surgery in early pregnancy causes no harm to the fetus and should be encouraged once the diagnosis is confirmed. Delaying surgery may induce serious infection and jeopardize the lives of both the fetus and mother.

    2015-11-01

    Ultrasound examination of trauma patients is increasingly performed in prehospital services. It is unclear if prehospital sonographic assessments change patient management: providing prehospital diagnosis and treatment, determining choice of destination hospital, or treatment at the receiving hospital. This review aims to assess and grade the evidence that specifically examines whether prehospital ultrasound (PHUS) of the thorax and/or abdomen changes management of the trauma patient. A systematic review was conducted of trauma patients who had an ultrasound of the thorax or abdomen performed in the prehospital setting. PubMed, MEDLINE, Web of Science (CINAHL, EMBASE, Cochrane Central Register of Controlled Trials) and the reference lists of included studies were searched. Methodological quality was checked and risk of bias analysis performed, a level of evidence grade was assigned, and descriptive data analysis performed. 992 unique citations were identified, which included eight studies that met inclusion criteria with a total of 925 patients. There are no reports of randomised controlled trials. Heterogeneity exists between the included studies which ranged from a case series to retrospective and prospective non-randomised observational studies. Three studies achieved a 2+ Scottish Intercollegiate Guidelines Networks grade for quality of evidence and the remainder demonstrated a high risk of bias. The three best studies each provided examples of prehospital ultrasound positively changing patient management. There is moderate evidence that supports prehospital physician use of ultrasound for trauma patients. For some patients, management was changed based on the results of the PHUS. The benefit of ultrasound use in non-physician services is unclear. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Motor vehicle collisions are the leading cause of death for children ages 5 to 14. Enhancement of child occupant protection is partly dependent on the ability to accurately assess the interaction of child-size occupants with restraint systems. Booster seat design and belt fit are evaluated using child anthropomorphic test devices, such as the Hybrid III 6-year-old dummy., A biofidelic abdomen for the Hybrid III 6-year-old dummy is being developed by the Ford Motor Company to enhance the dummy’s ability to assess injury risk and further quantify submarining risk by measuring abdominal deflection. A practical measurement system for the biofidelic abdominal insert has been developed and demonstrated for three dimensional determination of abdominal deflection. Quantification of insert deflection is achieved via differential signal measurement using electrodes mounted within a conductive medium. Signal amplitude is proportional to the distance between the electrodes. A microcontroller is used to calculate distances between ventral electrodes and a dorsal electrode in three dimensions. This system has been calibrated statically, and its performance demonstrated in a series of sled tests. Deflection measurements from the instrumented abdominal insert indicate performance differences between two booster seat designs, yielding an average peak anterior to posterior displacement of the abdomen of 1.0 ± 3.4 mm and 31.2 ± 7.2 mm for the seats, respectively. Implementation of a 6-year-old abdominal insert with the ability to evaluate submarining potential will likely help safety researchers further enhance booster seat design and interaction with vehicle restraint systems , and help to further understand child occupant injury risk in automobile collisions.

    2017-01-01

    Soft-tissue sarcomas occurring in the abdomen and pelvis are an uncommon but important group of malignancies. Recent changes to the World Health Organization classification of soft-tissue tumors include the movement of gastrointestinal stromal tumors (GISTs) into the soft-tissue tumor classification. GIST is the most common intraperitoneal sarcoma. Liposarcoma is the most common retroperitoneal sarcoma, and leiomyosarcoma is the second most common. GIST, liposarcoma, and leiomyosarcoma account for the majority of sarcomas encountered in the abdomen and pelvis and are discussed in part 1 of this article. Undifferentiated pleomorphic sarcoma (previously called malignant fibrous histiocytoma), dermatofibrosarcoma protuberans, solitary fibrous tumor, malignant peripheral nerve sheath tumor, rhabdomyosarcoma, extraskeletal chondro-osseous sarcomas, vascular sarcomas, and sarcomas of uncertain differentiation uncommonly arise in the abdomen and pelvis and the abdominal wall. Although these lesions are rare sarcomas and their imaging features overlap, familiarity with the locations where they occur and their imaging features is important so they can be diagnosed accurately. The anatomic location and clinical history are important factors in the differential diagnosis of these lesions because metastasis, more-common sarcomas, borderline fibroblastic proliferations (such as desmoid tumors), and endometriosis have imaging findings that overlap with those of these uncommon sarcomas. In this article, the clinical, pathologic, and imaging findings of uncommon soft-tissue sarcomas of the abdomen and pelvis and the abdominal wall are reviewed, with an emphasis on their differential diagnosis.

    To quantify changes in private insurance payments for and utilization of abdominal/pelvic computed tomography scans (CTs) after 2011 changes in CPT coding and Medicare reimbursement rates, which were designed to reduce costs stemming from misvalued procedures. TruvenHealth Analytics MarketScan Commercial Claims and Encounters database. We used difference-in-differences models to compare combined CTs of the abdomen/pelvis to CTs of the abdomen or pelvis only. Our main outcomes were inflation-adjusted log payments per procedure, daily utilization rates, and total annual payments. Claims data were extracted for all abdominal/pelvic CTs performed in 2009-2011 within noncapitated, employer-sponsored private plans. Adjusted payments per combined CTs of the abdomen/pelvis dropped by 23.8 percent (p pelvis decreased in 2011 despite the increased utilization. Private insurance payments for combined CTs of the abdomen/pelvis declined and utilization accelerated significantly after 2011 policy changes. While growth in total annual payments was contained in 2011, it may not be sustained if 2011 utilization trends persist. © Health Research and Educational Trust.

    Full Text Available Abstract Background The aim was to determine the incidence of seed migration not only to the chest, but also to the abdomen and pelvis after transperineal interstitial prostate brachytherapy with loose 125I seeds. Methods We reviewed the records of 267 patients who underwent prostate brachytherapy with loose 125I seeds. After seed implantation, orthogonal chest radiographs, an abdominal radiograph, and a pelvic radiograph were undertaken routinely to document the occurrence and sites of seed migration. The incidence of seed migration to the chest, abdomen, and pelvis was calculated. All patients who had seed migration to the abdomen and pelvis subsequently underwent a computed tomography scan to identify the exact location of the migrated seeds. Postimplant dosimetric analysis was undertaken, and dosimetric results were compared between patients with and without seed migration. Results A total of 19,236 seeds were implanted in 267 patients. Overall, 91 of 19,236 (0.47% seeds migrated in 66 of 267 (24.7% patients. Sixty-nine (0.36% seeds migrated to the chest in 54 (20.2% patients. Seven (0.036% seeds migrated to the abdomen in six (2.2% patients. Fifteen (0.078% seeds migrated to the pelvis in 15 (5.6% patients. Seed migration occurred predominantly within two weeks after seed implantation. None of the 66 patients had symptoms related to the migrated seeds. Postimplant prostate D90 was not significantly different between patients with and without seed migration. Conclusion We showed the incidence of seed migration to the chest, abdomen and pelvis. Seed migration did not have a significant effect on postimplant prostate D90.

    A pathologic splenic rupture refers to a rupture without trauma. A splenic rupture as the initial manifestation of acute myeloid leukemia is extremely rare. In this study, we described a rare case of acute myeloid leukemia presenting principally as an acute abdomen due to a pathologic splenic rupture in a 35-year old male patient. We can assert that a pathologic splenic rupture in hematologic diseases is a potentially life-threatening complication, which necessitates immediate operative intervention. Any such patient complaining about left upper abdominal tenderness should be closely observed, and further diagnostic investigations (ultrasonograph of the abdomen, abdominal CT scan) should be initiated in order to rule out a splenic rupture. The oncologist should be aware of this rare initial presentation of acute myeloid leukemia (AML) M2, as the condition generally necessitates a prompt splenectomy.

    To assess the effect of varying iodine flow rate (IFR) and iodine concentration on the quality of virtual unenhanced (VUE) images of the abdomen obtained with dual-energy CT. 94 subjects underwent unenhanced and triphasic contrast-enhanced CT scan of the abdomen, including arterial phase, portal venous phase, and delayed phase using dual-energy CT. Patients were randomized into 4 groups with different IFRs or iodine concentrations. VUE images were generated at 70 keV. The CT values, image noise, SNR and CNR of aorta, portal vein, liver, liver lesion, pancreatic parenchyma, spleen, erector spinae, and retroperitoneal fat were recorded. Dose-length product and effective dose for an examination with and without plain phase scan were calculated to assess the potential dose savings. Two radiologists independently assessed subjective image quality using a five-point scale. The Kolmogorov-Smirnov test was used first to test for normal distribution. Where data conformed to a normal distribution, analysis of variance was used to compare mean HU values, image noise, SNRs and CNRs for the 4 image sets. Where data distribution was not normal, a nonparametric test (Kruskal-Wallis test followed by stepwise step-down comparisons) was used. The significance level for all tests was 0.01 (two-sided) to allow for type 2 errors due to multiple testing. The CT numbers (HU) of VUE images showed no significant differences between the 4 groups (p > 0.05) or between different phases within the same group (p > 0.05). VUE images had equal or higher SNR and CNR than true unenhanced images. VUE images received equal or lower subjective image quality scores than unenhanced images but were of acceptable quality for diagnostic use. Calculated dose-length product and estimated dose showed that the use of VUE images in place of unenhanced images would be associated with a dose saving of 25%. VUE images can replace conventional unenhanced images. VUE images are not affected by varying iodine

    CT plays an important role in depicting gunshot wounds in parenchymal and hollow organs in the abdomen. Relative to other techniques and to emergency laparotomy, CT permits good assessment of abdominal content, major injuries and changes in other districts, such as chest, pelvis and skull. We investigated the yield and role of CT in diagnosing abdominal gunshot wounds, with their rich and varied radiological signs and associated injuries. We retrospectively reviewed the findings of 30 patients with abdominal gunshot wounds examined in 4 years at Loreto-Mare Hospital, Naples. All patients were men, age ranging 19-54 years (mean: 35); 6 of them were not from the European Union. Examinations were carried out from diaphragm to pubis with i.v. contrast injection and the CT angiography technique. CT was integrated with chest studies in 6 cases and with skull studies in 5. Subsequent CT follow-ups were necessary in 12 cases submitted to conservative treatment. Liver was the most damaged parenchyma, with hemorrhage and lacerocontusion in 7 cases and mashed in 1 case; spleen was involved in 4 cases; hemoperitoneum was found in 18 cases. Diaphragm was involved in 5 cases and pancreas in 2; gallbladder, stomach and duodenum were involved in 1 case each and jejunum-ileum and colon in 3 and 6 cases, respectively. CT showed renal injury in 3 cases and bladder injury in 2. Eight patients had vertebral gunshot damage. Pneumothorax, hemothorax and lacerocontusion were found in 7 cases; brain was injured in 4 cases and limbs in 16. Tissue damage extent depends on the speed and kinetic energy the bullet carries into the abdomen. Abdominal radiography shows the bullet and its site, pneumoperitoneum from gastrointestinal perforation, crash bone injuries, vertebral trauma and subcutaneous emphysema. Instead, CT depicts early parenchymal damage and vascular injury and thus becomes a complete and necessary tool for imaging gunshot wounds. CT provides early diagnostic information which

    To develop and refine qualitative mapping and quantitative analysis techniques to define 'thermal territories' of the post-partum abdomen, the caesarean section site and the infected surgical wound. In addition, to explore women's perspectives on thermal imaging and acceptability as a method for infection screening. Prospective feasibility study undertaken at a large University teaching hospital, Sheffield UK. Infrared thermal imaging of the abdomen was undertaken at the bedside on the first two days after elective caesarean section. Target recruitment: six women in each of three body mass index (BMI) categories (normal, 18.5-24.9 kg/m²; overweight 25-29.9 kg/m²; obese ≥30 kg/m²). Additionally, women presenting to the ward with wound infection were eligible for inclusion in the study. Perspectives on the use of thermal imaging and its practicality were also explored via semi-structured interviews and analysed using thematic content analysis. We recruited 20 women who had all undergone caesarean section. From the booking BMI, eight women were obese (including two women with infected wounds), seven women were overweight and five women had a normal BMI. Temperature (ºC) profiling and pixel clustering segmentation (hierarchical clustering-based segmentation, HCS) revealed characteristic features of thermal territories between scar and adjacent regions. Differences in scar thermal intensity profiles exist between healthy scars and infected wounds; features that have potential for wound surveillance. The maximum temperature differences (∆T) between healthy skin and the wound site exceed 2º C in women with established wound infection. At day two, two women had a scar thermogram with features observed in the 'infected' wound thermogram. Thermal imaging at early and later times after caesarean birth is feasible and acceptable. Women reported potential benefits of the technique for future wound infection screening. Thermal intensity profiling and HCS for pixel

    Full Text Available The presence of nanoparticles on the body of the honeybee Apis dorsata Fabricius, was investigated for the first time to better understand the bee’s behaviour. These have been observed by using Scanning Electron Microscopy (SEM, Transmission Electron Microscopy (TEM and confirmed by Atomic Force Microscopy (AFM. Our study clearly denotes that the Indian rock honey bee Apis dorsata possess calcium silicate and calcium phosphate nanoparticles on its body surface of 5-50 nm in diameter. In particular, the nanoparticles on the abdomen and thorax of A. dorsata have an average diameter of about 10 nanometers and they are smaller than those found on wings of the same bees which are about 20 nanometers. The nanoparticles found are different of the ones previously observed on honey bees or other insects. The origin and role of these natural nanoparticles on the body of the Indian rock bee need to be to be further investigated; more research in the subject might raise important aspects in relation to the conservation of these unique pollinators.

    2011-01-01

    Venous injuries as a result of blunt trauma are rare. Even though current protocols for multidetector computed tomography (CT) of patients with trauma are designed to evaluate primarily the solid organs and arteries, blunt venous injuries may nevertheless be identified, or at least suspected, on the basis of the multidetector CT findings. Venous injuries are associated with high morbidity and mortality rates. Diagnosis of a possible venous injury is crucial because the physical findings of a venous injury are nonspecific and may be absent. This article aims to make the radiologist aware of various venous injuries caused by blunt trauma and to provide helpful hints to aid in the identification of venous injuries. Multidetector CT technology, in combination with interactive manipulation of the raw dataset, can be useful in the creation of multiplanar reconstructed images and in the identification of a venous injury caused by blunt trauma. Familiarity with direct and indirect signs of venous injuries, as well as with examples of blunt traumatic venous injuries in the chest, abdomen, and pelvis, will help in the diagnosis of these injuries.

    Postpregnancy full-length diastasis of the recti abdominis muscles is a common condition occasionally associated with atrophy of the subcutaneous fat located at the midline above and below the umbilicus. The authors report a preliminary clinical experience with the suprapubic flap to prevent the late postoperative contour deformities of the postpregnancy abdomen. Between January 2005 and January 2015, all female patients undergoing abdominoplasty with the suprapubic flap were included in the present study. Electronic clinical records were reviewed to analyze the patients' ages, body mass index (BMI) scores, pregnancies, risk factors, and operative times, followed by a telephone-based survey to measure patient satisfaction. Twenty-two patients were included. Their ages ranged from 19 to 36 years (mean, 27 years) and their BMI ranged from 17.5 to 22.5 kg/m2 (mean, 20.5 kg/m2). Postoperative follow up ranged from 12 months to 10 years (mean, 89 months). All patients had experienced at least one pregnancy and many of them multiple or twin pregnancies. Umbilical hernias were present in 18 patients. There were 5 unusual cases: one hematoma, one seroma, and three cases of hypertrophic scarring. Thirteen additional minutes were required, on average, to associate the flap. All patients were satisfied or very satisfied with the results. The suprapubic dermoadipose flap is an effective option to prevent the midline depression that would otherwise remain on the hypogastric region of postpregnant slim women with midline fat tissue atrophy. 4.

    To compare the image quality between fine focal spot size (FFSS) and standard focal spot size (SFSS) in computed tomography of the abdomen and pelvis (CTAP) This retrospective review included all consecutive adult patients undergoing contrast-enhanced CTAP between June and September 2014. Two blinded radiologists assessed the margin clarity of the abdominal viscera and the detected lesions using a five-point grading scale. Cohen's kappa test was used to examine the inter-observer reliability between the two reviewers for organ margin clarity. Mann-Whitney U testing was utilised to assess the statistical difference of the organ and lesion margin clarity. 100 consecutive CTAPs were recruited. 52 CTAPs were examined with SFSS of 1.1 x 1.2 mm and 48 CTAPs were examined with FFSS of 0.6 x 0.7 mm. Results showed that there was substantial agreement for organ margin clarity (mean κ = 0.759, p < 0.001) among the reviewers. FFSS produces images with clearer organ margins (U = 76194.0, p < 0.001, r = 0.523) and clearer lesion margins (U = 239, p = 0.052, r = 0.269). FFSS CTAP improves image quality in terms of better organ and lesion margin clarity. Fine focus CT scanning is a novel technique that may be applied in routine CTAP imaging. (orig.)

    Full Text Available Bladder rupture is a rare condition associated with significant morbidityand mortality. It is classified into traumatic, nontraumatic or idiopathic andspontaneous. The nonspecific initial clinical presentation is followed bydiscomfort in the lower abdomen, oliguria, hematuria and ascitis. Laboratoryabnormalities simulate the picture of acute renal failure and occurs by amechanism called auto reverse dialysis, with absorption of excreta throughthe peritoneal membrane. The authors describe a case of bladder rupturein morphologically and functionally normal urinary bladder associated withalcohol intake in young healthy man, manifested by abdominal discomfort,pseudo renal failure and massive ascitis. The diagnosis was made by anabdominal multidetector computed tomography confirmed by the finding of7 cm laceration at laparotomy.

    Purpose: To analysis the impact of scan length on patient doses in abdomen/pelvis CT diagnosis of each hospital. Methods: Scan length of 7 hospitals from abdomen/pelvis CT diagnosis was surveyed in Korea. Surveyed scan lengths were additional distance above diaphragm and distance below pubic symphysis except for standard scan range between diaphragm and pubic symphysis. Patient dose was estimated for adult male and female according to scan length of each hospital. CT-Expo was used to estimate the patient dose under identical equipment settings (120 kVp, 100 mAs, 10 mm collimation width, etc.) except scan length. Effective dose was calculated by using tissue weighting factor of ICRP 103 recommendation. Increase rate of effective dose was calculated comparing with effective dose of standard scan range Results: Scan lengths of abdomen/pelvis CT diagnosis of each hospital were different. Also effective dose was increased with increasing the scan length. Generally increasing the distance above diaphragm caused increase of effective dose of male and female, but increasing the distance below pubic symphysis caused increase of effective dose of male. Conclusion: We estimated the patient dose according to scan length of each hospital in abdomen/pelvis CT diagnosis. Effective dose was increased by increasing the scan length because dose of organs with high tissue weighting factor such as lung, breast, testis were increased. Scan length is important factor on patient dose in CT diagnosis. If radiologic technologist interested in patient dose, decreasing the unnecessary scan length will decrease the risk of patients from radiation.

    The morphologic aspect of abdominal tuberculosis are evaluated by C.T. The necrotising tuberculosis of the genitourinary tract presents course cystic lesions of fluid density. Similar morphologic criteria are seen in ileocecal tuberculosis. The peritoneal tuberculosis is characterized by large soft tissue masses of a high density which can be found in nearly all areas of the abdomen. The increased morbidity of tuberculosis in people from foreign countries living in the Federal Republic of Germany is pointed out.

    Definitive abdominal closure may not be possible for several days or weeks after laparotomy in damage-control surgery, abdominal compartment syndrome and intraabdominal sepsis, until the patient has stabilized. Vacuum-assisted closure (VAC therapy(®), KCI, San Antonio, TX, USA) and abdominal re-approximation anchor system (ABRA, Canica, Almonte, Ontario, Canada) are novel techniques in delayed closure of open abdomen. Our aim is to present the use of these strategies in the management of 7 patients with open abdomen. Between August 2010 and December 2011, 7 patients with severe peritonitis were stabilized by laparotomy and treated with either ABRA system or ABRA system in conjunction with VAC dressing. VAC dressing applied to 4 patients initially and followed by ABRA. ABRA was applied alone to remaining 3 patients. Demographic data and patient characteristics, timing of VAC dressing and ABRA system were recorded. ICU and hospital stay and development of incisional hernia were also recorded. Stage of open abdomen, width of abdominal defect, extent to damage to fascia, and pressure sores were staged. The mean duration with VAC dressing before ABRA application was 18 days. The mean duration of ABRA application was 53 days. The average width of the abdominal defect was 18 cm. The average length of defect was 20.8 cm. Delayed primary abdominal closure was accomplished in 6 patients without further surgery. Incisional hernia with a small abdominal defect developed in 2 patients. Abdominal re-approximation anchor system and VAC dressing can be used separately or in conjunction with each other for closure of delayed open abdomen successfully.

    The aim of this paper was to review the literature on vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) in open abdomen therapy. It was designed as systematic review of observational studies. A Pub Med, EMBASE and Cochrane search from 2007/01-2016/07 was performed combining the Medical Subject Headings "vacuum", "mesh-mediated fascial traction", "temporary abdominal closure", "delayed abdominal closure", "open abdomen", "abdominal compartment syndrome", "negative pressure wound therapy" or "vacuum assisted wound closure". Eleven original studies were found including patients numbering from 7 to 111. Six studies were prospective and five were retrospective. Nine studies were on mixed surgical (n = 9), vascular (n = 6) and trauma (n = 6) patients, while two were exclusively on vascular patients. The primary fascial closure rate per protocol varied from 80-100%. The time to closure of the open abdomen varied between 9-32 days. The entero-atmospheric fistula rate varied from 0-10.0%. The in-hospital survival rate varied from 57-100%. In the largest prospective study, the incisional hernia rate among survivors at 63 months of median follow-up was 54% (27/50), and 16 (33%) repairs out of 48 incisional hernias were performed throughout the study period. The study patients reported lower short form health survey (SF-36) scores than the mean reference population, mainly dependent on the prevalence of major co-morbidities. There was no difference in SF-36 scores or a modified ventral hernia pain questionnaire (VHPQ) at 5 years of follow up between those with versus those without incisional hernias. A high primary fascial closure rate can be achieved with the vacuum-assisted wound closure and meshmediated fascial traction technique in elderly, mainly non-trauma patients, in need of prolonged open abdomen therapy.

    The open abdomen has become an accepted treatment option of critically ill patients with severe intra-abdominal conditions. Fascial closure is a particular challenge in patients with peritonitis. This study investigates whether fascial closure rates can be increased in peritonitis patients by using an algorithm that combines vacuum-assisted wound closure and mesh-mediated fascial traction. Moreover, fascial closure rates for patients with peritonitis, trauma or abdominal compartment system (ACS) are compared. Data were collected prospectively from all patients who underwent open abdomen management at our institution from 2006 to 2012. All patients were treated under a standardised algorithm that combines vacuum-assisted closure and mesh placement at the fascial level. During the study period, 53 patients (mean age 53 years) underwent open abdomen management for a mean duration of 15 days. Indications for leaving the abdomen open were peritonitis (51 %), trauma (26 %), and ACS or abdominal wall dehiscence (23 %). The fascial closure rate was 79 % in an intention-to-treat analysis and 89 % in a per-protocol analysis. Mortality was 13 %. No patient developed an enteroatmospheric fistula or abdominal wall dehiscence after closure. The mean duration of treatment was significantly longer in peritonitis patients (20 days) than in patients without peritonitis (10 days) (p = 0.03). There were no significant differences in fascial closure rates between patients with peritonitis (87 %), trauma (85 %), and ACS or abdominal wall dehiscence (100 %) (p = 0.647). Regardless of the underlying pathology, high fascial closure rates can be achieved using a combination of vacuum-assisted closure and mesh-mediated fascial traction.

    The purpose of this study was to investigate the imaging characteristics of solitary fibrous tumor (SFT) in the abdomen and pelvis. Nine cases of SFT confirmed by surgery and pathology were retrospectively analyzed in terms of computed tomography (CT, eight cases) and magnetic resonance imaging (MRI, one case). SFT were located in the retroperitoneum (4/9), abdominal cavity (1/9), pelvis (4/9). Eight cases were single (8/9) and one case (1/9) with three tumors. The average tumor size of 11 lesions was 9.7 cm (4.7-20 cm). Nine tumors were round or ovoid, and two lesions were irregular. The CT value of the plain scans ranged from 33 to 43 Hounsfield units (HU, mean 37.6 HU) in five cases. Arterial-phase CT found solid parts demonstrate avid enhancement (eight cases) and five of them presented with multiple circuitous vessels along the periphery with a CT value of 68-89 HU (mean 76.6 HU). In the venous and delayed phases, enhancement was strengthened progressively. The CT values at venous (eight cases) and delayed phases (five cases) were 108-115 and 112-123 HU respectively, with averages of 109.8 and 114.8 HU. Patch or nodular no-enhanced areas were observed in eight cases during the enhanced phases. One case showed isointensity on T1-weighted images and high signal intensity on T2-weighted images accompanied by linear or curvilinear hypointense lines. Intense enhancements along with linear no-enhancement areas are seen in the arterial and venous phases. The possibility of SFT should be considered when a single or multiple masses with sharp border, inhomogeneous density or signal are detected, especially, with inhomogeneous intense enhancement in the arterial phase being maintained in the venous and delayed phases.

    Communication by substrate-borne mechanical signals is widespread among animals but remains one of their least understood communication channels. Past studies of vibrational communication in insects have been oriented predominantly to communication during mating, showing that species- and sex-specific vibrational signals enable recognition and localization of potential mates on continuous solid substrates. No special attention has been paid to vibrational signals with less obvious specificity as well as to the possibility of vibrational communication across substrates that are not in physical contact. We aimed to reinvestigate emission of the aforementioned vibrational signals transmitted through a plant in the stink bug Euschistus heros (Pentatomidae: Pentatominae) and to check whether individuals are able to communicate across adjecent, physically separated substrates. We used laser vibrometry for registration of substrate-borne vibrational signals on a bean plant. Using two bean plants separated for 3 to 7 cm between two most adjacent leaves, we investigated the possibility of transmission of these signals through air. Our study showed that males and females of E. heros communicate using tremulatory, percussion and buzzing signals in addition to the previously described signals produced by vibrations of the abdomen. Contrary to the latter, the first three signal types did not differ between sexes or between pentatomid species. Experiments with two physically separated plants showed significant searching behaviour and localization of vibrational signals of an E. heros male or a female, in response to abdominal vibration produced signals of a pair duetting on the neighbouring plant, in comparison to control where no animals were on the neighbouring plant. We also confirmed that transmission through air causes amplitude and frequency decay of vibrational signals, which suggests high-amplitude, low-frequency tremulatory signals of these stink bugs their most

    The diseases affecting the large intestine represent a diagnostic problem in adult patients with acute abdomen, especially when clinical symptoms are not specific. The role of the diagnostic imaging is to help clinicians and surgeons in differential diagnosis for an efficient early and prompt therapy to perform. This review article summarizes the imaging spectrum of findings of colonic acute disease, from mechanical obstruction to inflammatory diseases and perforation, offering keys to problem solving in doubtful cases as well as discussing regarding the more indicated imaging method to use in emergency, particularly MDCT.

    The present study was aimed at describing key computed tomography and magnetic resonance imaging findings in patients with acute abdominal pain derived from pelvic inflammatory disease. Two radiologists consensually selected and analyzed computed tomography and magnetic resonance imaging studies performed between January 2010 and December 2011 in patients with proven pelvic inflammatory disease leading to presentation of acute abdomen. Main findings included presence of intracavitary fluid collections, anomalous enhancement of the pelvic excavation and densification of adnexal fat planes. Pelvic inflammatory disease is one of the leading causes of abdominal pain in women of childbearing age and it has been increasingly been diagnosed by means of computed tomography and magnetic resonance imaging supplementing the role of ultrasonography. It is crucial that radiologists become familiar with the main sectional imaging findings in the diagnosis of this common cause of acute abdomen (author)

    Inflammatory changes of the intestine leading to acute abdomen could represent a frequent diagnostic challenge for radiologists actively involved in the emergency area. MDCT imaging findings needs to be evaluated considering the clinical history and symptoms and other abdominal findings that could be of help in differential diagnosis. Several protocols have been suggested and indicated in the imaging of patient with acute intestine. However, a CT protocol in which the precontrast scanning of the abdomen is followed by i.v. administration of contrast medium using the 45-55 s delay could be effective for an optimal visualization of the bowel wall. It is important to learn to recognize how the intestine reacts to the injury and how it 'talks', in order to become aware of the different patterns of disease manifestation related to an acute intestinal condition, for an effective diagnosis of active and acute inflammatory bowel disease.

    Full Text Available The emergent abdominal surgeries from either of traumatic or non traumatic causes can result in situations in which the abdominal wall cannot initially be closed. Many techniques have been reported for temporary coverage of the exposed viscera, but the result of various techniques remains unclear. During 94 months, 19 critically ill patients whit an open abdomen underwent surgery using plastic bags (Bogotá bag. The study population comprised of 11 (57.9% male and 8 (42.1% female with an average age of 32.26+14.8 years. The main indications for temporary abdominal coverage were as follows: planned reoperation in 11 (57.9% patients, subjective judgment that the fascia closure is too tight in 6 (31.6% patient's damage control surgery in one patient (5.3% and development of abdominal compartment surgery in one patient (5.3%. Surgical conditions requiring temporary abdominal closure was severe post operative peritonitis in 9 (47.4% patients, post operative intestinal fistula in 4 (21.1% patients, post traumatic intra abdominal bleeding in 3 (15.8% patients and intestinal obstructions in 3 (15.8% patients. Length of hospitalization was 45+23.25 days and the mean total number of laparotomies was 6.2+3.75 times per patient. Three bowel fistulas occurred due to a missed injury at the time of initial operation that was discovered during changing the plastic sheet. They were unrelated to coverage technique. All of them were treated by repair of the defect and serosal patch by adjacent bowel loop. Only one (10.0% patient underwent definitive closure within 6 months of initial operation. The remaining survivor has declined to have hernia repaired. There were 4 (%21.1 early postoperative deaths that were not related to the abdominal coverage technique.

    The great anterior radiculomedullary artery, also known as the artery of Adamkiewicz (AKA), is a small-caliber vessel which arises from the intercostal or lumbar arteries branching out from the aorta. The aim of this study was to evaluate detection of the AKA, as well as its level and side of origin, with multi-slice contrast enhanced computed tomography (MSCT) of the abdomen and thorax performed during everyday clinical practice, and to compare the results with the literature. The study retrospectively evaluated 200 consecutive MSCT images of the thoracic and thoracoabdominal aorta performed at Wroclaw Medical University's Department of General and Interventional Radiology and Neuroradiology as part of normal clinical work-ups. The CT examinations were performed with a 64-slice CT scanner. Arterial-phase images were analyzed for detection of the AKA and for anatomical variants of the AKA. Recognition of the AKA was achieved in 43 of 200 patients (21.5%). Out of these 43 cases, the AKA originated on the left side in 36 instances (83.7%) - a significantly higher number than on the right side (only in 6 cases, 14%); in one case (2.3%) it arose from both sides (p < 0.05, T-test). Most of the AKAs (24 cases, 55.8%) originated on the left side at level T11 or T12. In 13 patients (30.2%) the AKA arose from T11 or from T12 intercostal arteries. The origin of the AKA varied greatly and ranged from T5 (2.3%) to L2 (2.3%). The AKA is characterized by left-side lateralization and is associated with a wide range of origin, from T5 to L2. Detection of the AKA is, relatively speaking, rarely possible in routine clinical CT in the arterial phase - only in 1/5 of the patients. Therefore it is necessary to perform dedicated, individual arterial phase bolus tracking enhancement CT scans from the T5 to L3 level.

    Full Text Available Background: The furosemide drip (FD, in addition to improving volume overload respiratory failure, has been used to decrease fluid in attempts to decrease intra-abdominal and abdominal wall volumes to facilitate fascial closure. The purpose of this study is to evaluate the FD and the associated rate of primary fascial closure following trauma damage control laparotomy (DCL. Materials and Methods: From January 2004 to September 2008, a retrospective review from a single institution Trauma Registry of the American College of Surgeons dataset was performed. All DCLs greater than 24 h who had a length of stay for 3 or more days were identified. The study group (FD+ and control group (FD- were compared. Demographic data including age, sex, probability of survival, red blood cell transfusions, initial lactate, and mortality were collected. Primary outcomes included primary fascial closure and primary fascial closure within 7 days. Secondary outcomes included total ventilator days and LOS. Results: A total of 139 patients met inclusion criteria: 25 FD+ and 114 FD-. The 25 FD+ patients received the drug at a median 4 days post DCL. Demographic differences between the groups were not significantly different, except that initial lactate was higher for FD- (1.7 vs 4.0; P=0.03. No differences were noted between groups regarding successful primary fascial closure (FD+ 68.4% vs FD- 64.0%; P=0.669, or closure within 7 days (FD+13.2% vs FD- 28.0%; P=0.066 of original DCL. FD+ patients suffered more open abdomen days (4 [2-7] vs 2 [1-4]; P=0.001. FD+ did not demonstrate an association with primary fascial closure [Odds ratio (OR 1.5, 95% confidence interval (CI 0.260-8.307; P=0.663]. FD+ patients had more ventilator days and longer Intensive Care Unit (ICU/hospital LOS (P<0.01. Conclusion: FD use may remove excess volume; however, forced diuresis with an FD is not associated with an increased rate of primary closure after DCL. Further studies are warranted to

    High intensity focused ultrasound (HIFU) enables highly localized, non-invasive tissue ablation and its efficacy has been demonstrated in the treatment of a range of cancers, including those of the kidney, prostate and breast. HIFU offers the ability to treat deep-seated tumours locally, and potentially bears fewer side effects than more invasive treatment modalities such as resection, chemotherapy and ionizing radiation. There remains however a number of significant challenges which currently hinder its widespread clinical application. One of these challenges is the need to transmit sufficient energy through the ribcage to ablate tissue at the required foci whilst minimizing the formation of side lobes and sparing healthy tissue. Ribs both absorb and reflect ultrasound strongly. This sometimes results in overheating of bone and overlying tissue during treatment, leading to skin burns. Successful treatment of a patient with tumours in the upper abdomen therefore requires a thorough understanding of the way acoustic and thermal energy is deposited. Previously, a boundary element approach based on a Generalized Minimal Residual (GMRES) implementation of the Burton-Miller formulation was developed to predict the field of a multi-element HIFU array scattered by human ribs, the topology of which was obtained from CT scan data (Gélat et al 2011 Phys. Med. Biol. 56 5553-81). The present paper describes the reformulation of the boundary element equations as a least-squares minimization problem with nonlinear constraints. The methodology has subsequently been tested at an excitation frequency of 1 MHz on a spherical multi-element array in the presence of ribs. A single array-rib geometry was investigated on which a 50% reduction in the maximum acoustic pressure magnitude on the surface of the ribs was achieved with only a 4% reduction in the peak focal pressure compared to the spherical focusing case. This method was then compared with a binarized apodization approach

    Full Text Available Up to the present, the optimal time to close an open abdomen remains controversial. This study was designed to evaluate whether early fascial abdominal closure had advantages over delayed approach for open abdomen populations. Medline, Embase, and Cochrane Library were searched until April 2013. Search terms included “open abdomen,” “abdominal compartment syndrome,” “laparostomy,” “celiotomy,” “abdominal closure,” “primary,” “delayed,” “permanent,” “fascial closure,” and “definitive closure.” Open abdomen was defined as “fail to close abdominal fascia after a laparotomy.” Mortality, complications, and length of stay were compared between early and delayed fascial closure. In total, 3125 patients were included for final analysis, and 1942 (62% patients successfully achieved early fascial closure. Vacuum assisted fascial closure had no impact on pooled fascial closure rate. Compared with delayed abdominal closure, early fascial closure significantly reduced mortality (12.3% versus 24.8%, RR, 0.53, P<0.0001 and complication incidence (RR, 0.68, P<0.0001. The mean interval from open abdomen to definitive closure ranged from 2.2 to 14.6 days in early fascial closure groups, but from 32.5 to 300 days in delayed closure groups. This study confirmed clinical advantages of early fascial closure over delayed approach in treatment of patients with open abdomen.

    ICRP 103 specifies reference dose levels to be used during radiographic exams. Usually, the radiographer qualitative determines the best radiographic technique (kV and mAs) in order to obtain better image quality with the lowest dose. The objective of this study was to evaluate the doses used in examination of the chest, abdomen and skull in patients of different physical sizes, and infer about the amount of dose required to maintain acceptable radiological contrast in patients of different physical sizes. Techniques used by experienced radiographers of HC-FMB-UNESP for examinations of the chest (PA), abdomen (AP) and skull (AP) for patients of different thickness (small, medium and thick body) were obtained. Dose measurements were performed referring to all kV/mAs combinations. PMMA phantoms were placed below the ionization chamber. The Signal Difference Noise Ratio (SDNR) of the images of the phantoms were calculated from an area of contrast and a region of normal tissue. The Figure of Merit (FoM) was calculated for each of the exam modality. Measured FoM decreased according to the thickness of the chest and abdomen, indicating the need to increase the dose level to maintain the same level of image contrast. Patients thicker usually end up getting more than twice the dose of lean patients. Required image quality levels for correct diagnosis should be obtained using dose levels as low as reasonably practicable examination. These factors highlight the need for a program of quality assurance and effective dose studies in actual service. (author)

    The use of three physical image quality metrics, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and mean effective noise equivalent quanta (eNEQm) have recently been examined by our group for their appropriateness in the calibration of an automatic exposure control (AEC) device for chest radiography with an Agfa computed radiography (CR) imaging system. This study uses the same methodology but investigates AEC calibration for abdomen, pelvis and spine CR imaging. AEC calibration curves were derived using a simple uniform phantom (equivalent to 20 cm water) to ensure each metric was held constant across the tube voltage range. Each curve was assessed for its clinical appropriateness by generating computer simulated abdomen, pelvis and spine images (created from real patient CT datasets) with appropriate detector air kermas for each tube voltage, and grading these against reference images which were reconstructed at detector air kermas correct for the constant detector dose indicator (DDI) curve currently programmed into the AEC device. All simulated images contained clinically realistic projected anatomy and were scored by experienced image evaluators. Constant DDI and CNR curves did not provide optimized performance but constant eNEQm and SNR did, with the latter being the preferred calibration metric given that it is easier to measure in practice. This result was consistent with the previous investigation for chest imaging with AEC devices. Medical physicists may therefore use a simple and easily accessible uniform water equivalent phantom to measure the SNR image quality metric described here when calibrating AEC devices for abdomen, pelvis and spine imaging with Agfa CR systems, in the confidence that clinical image quality will be sufficient for the required clinical task. However, to ensure appropriate levels of detector air kerma the advice of expert image evaluators must be sought.

    Multiple techniques have been introduced to obtain fascial closure for the open abdomen. Vacuum-assisted closure has reduced but not eliminated the use of either split-thickness skin grafts to cover the exposed bowel or mesh (prosthetic or biological) approximation of the fascia. We hypothesized that a sequential closure technique performed by a systematic protocol would achieve a higher rate of primary fascial closure than other described techniques. Our technique of sequential fascial closure was initiated in 2005. Patients with a postinjury open abdomen undergoing the technique were compared with those patients who did not follow the protocol. In brief, vacuum-assisted closure white sponges cover the bowel; the fascia is placed under moderate tension over the white sponges with no. 1-polydioxanone sutures; the black sponge is placed on top of this with the standard occlusive dressing; patients undergo partial fascial closure and replacement of the sponge sandwich every 2 days until completely closed. Protocol violations were defined as not returning to the operating room every other day and absence of fascial retention sutures. Patients who died before return to the operating room in the first 48 hours were excluded. One hundred consecutive patients underwent damage control surgery during the five-year study period and survived to second laparotomy; 49 patients attained fascial closure at the second laparotomy. Fifty-one patients required an open abdomen after the second laparotomy and comprise the study population. The majority were men (80%) with a mean age of 34.7 years ± 2.0 years, mean injury severity score of 37.1 ± 2.4, and mean abdominal trauma index of 26.4 ± 2.1. Average initial base deficit was 15.7 ± 0.6 and 24-hour red cell transfusions were 20.4 ± 2.4 units. Of the 51 patients, 29 followed the protocol and 100% had fascial closure. Of the 22 patients who did not follow the protocol, 12 (55%) attained fascial closure. There were no significant

    Full Text Available Gastric volvulus, especially cases with an acute onset, may result in strangulation, perforation, peritonitis, shock and death. The disease is rarely seen in children, but early diagnosis and treatment is essential due to its life-threatening potential. In patients with acute gastric volvulus, the clinical Borchardt triade may be observed, which is characterized by acute severe pain and distension in the upper abdomen or lower thoracic region, retching and the inability to pass a nasogastric tube. In this article, We  aimed to emphasize the Borchardt’s triad by presenting a pediatric case who was diagnosed with Borchardt’s triad and who had acute mesenteric axial gastric volvulus which diaphragmatic hernia and mobile (wandering spleen were accompanied.

    2013-12-27

    The so-called "burst abdomen" has been described for many years and is a well-known clinical condition, whereas the concept of the "open abdomen" is relatively new. In clinical practice, both nosological entities are characterized by a complex spectrum of symptoms apparently disconnected, which in many cases poses a great challenge for surgical repair. In order to assess the management of these disorders in a more comprehensive and integral fashion, the concept of "acute postoperative open abdominal wall" (acute POAW) is presented, which in turn can be divided into "intentional" or planned acute POAW and "unintentional" or unplanned POAW. The understanding of the acute POAW as a single clinical process not only allows a better optimization of the therapeutic approach in the surgical repair of abdominal wall-related disorders, but also the stratification and collection of data in different patient subsets, favoring a better knowledge of the wide spectrum of conditions involved in the surgical reconstruction of the abdominal wall.

    Mismatches in the thickness of subcutaneous fat at the level of the umbilicus and suprapubic region can result in an unsightly bulge and an unfavourable result following standard abdominoplasty. This problem can be avoided by thinning the abdominoplasty flap. This study was carried out to assess the thickness of the subcutaneous fat layer at the level of the umbilicus and the supra-pubic region. Measurements of full thickness fat and the depth of Scarpa's fascia separating superficial and sub-Scarpa fat layers were taken from the CT scans in 69 women; mean age 52 years (range 30-79). The thickness of the skin and abdominal wall fat was an average of 7 mm thicker (max 22 mm; p superficial to Scarpa's fascia was an average of 19 mm at mid abdomen and 22 mm in the lower abdomen (p tension layer.

    To develop an ultrafast T1 mapping method for high-resolution, volumetric T1 measurements in the abdomen. The Look-Locker method was combined with a stack-of-spirals acquisition accelerated using three-dimensional (3D) through-time spiral GRAPPA reconstruction for fast data acquisition. A segmented k-space acquisition scheme was proposed and the time delay between segments for the recovery of longitudinal magnetization was optimized using Bloch equation simulations. The accuracy of this method was validated in a phantom experiment and in vivo T1 measurements were performed with 35 asymptomatic subjects on both 1.5 Tesla (T) and 3T MRI systems. Phantom experiments yielded close agreement between the proposed method and gold standard measurements for a large range of T1 values (200 to 1600 ms). The in vivo results further demonstrate that high-resolution T1 maps (2 × 2 × 4 mm(3)) for 32 slices can be achieved in a single clinically feasible breath-hold of approximately 20 s. The T1 values for multiple organs and tissues in the abdomen are in agreement with the published literature. A high-resolution 3D abdominal T1 mapping technique was developed, which allows fast and accurate T1 mapping of multiple abdominal organs and tissues in a single breath-hold. © 2015 Wiley Periodicals, Inc.

  10. Image-based guidance of percutaneous abdomen intervention based on markers for semi-automatic rigid registration.

    2014-12-01

    For percutaneous abdomen intervention (e.g. liver radiofrequency (RF) tumor ablation, liver biopsy), surgeons lack real-time visual feedback about the location of the needle on planning images, typically computed tomography (CT). One difficulty lies in tracking and synchronizing both the tool movement and the patient breathing motion. To verify the correspondence between rigid registration fiducial registration error signal and breathing phase. Designed markers that are clearly visible both in planning CT and on the patient during the intervention are proposed. Registration and breathing synchronization is then performed by a point-based approach. The method was tested in a clinical environment on 10 patients with liver cancer using 3D abdominal CT in the exhale position. Median rigid fiducial registration error (FRE) in the breathing cycle was used as a criterion to distinguish the inhale and exhale phase. The correlation between breathing phase and FRE value can be observed for every patient. We obtained mean median FRE equal to 9.37 mm in exhale positions and 15.56 mm in the whole breathing cycle. The presented real time approach, based on FRE calculation, was integrated in the clinical pipeline, and can help to select the best respiratory phase for needle insertion for percutaneous abdomen intervention, in cases where only 3D CT is performed. Moreover, this method allows semi-automated rigid registration to establish the correspondence between preoperative patient anatomical model and patient position.

    In spite of the improved MR-diagnosis of the abdomen, MRI is not used as a routine method for the diagnosis of inflammatory small bowel disease. The aim of this study was--after optimazation of the bowel opacification--the correlation of the findings obtained with enteroclysis and MRI in patients with known Crohns' disease. 60 patients between 17 and 72 years of age were investigated. First, an enteroclysis was performed in typical manner. The applicated methylcellulosis was blended with positive oral MR contrast media (Magnevist oral, Schering). After enteroclysis, MRI of the abdomen was performed using T1- and T2-weighted breathhold sequences (Flash 2D pre- and postcontrast and TSE) in axial and coronal planes. The length of the affected bowel and the stenosis seen with enteroclysis correlated well with the visible thickening of the small bowel wall and the stenosis seen in MRI. Using MRI, additional findings could be obtained in 28 patients, such as fistulas, abscesses or a hydronephrosis, or a better assessment of the stenosis was possible with MRI, because of the avoidance of overshadowing of the affected bowel loop with MRI. A brilliant MR-tomographic imaging of the small bowel is possible under the condition, that the small bowel contrast is optimal. The main prerequisite is a large filling volume of the small bowel to reach a homogeneous contrast and a good distension of the small bowel lumen.

    This paper presents an estimate of the effective dose from CTDI{sub vol} for exams of skull and abdomen in adult patients. Thereafter, measurements were taken of CTDI using an ionization chamber type pencil (Radcal Corportation, model 10 x 5 - 3CT) and cylindrical phantom of PMMA equivalent to regions of the skull (diameter = 16 cm) and abdomen (diameter = 32 cm). The results of effective dose for abdomen varied between 7,3 and 12,1 mSv and for skull between 1,4 and 5,0 mSv. Comparing with the literature data, for abdomen exams between 5 and 7 mSV and skull exams between 1 and 2 mSv, it is shown that it is possible to optimize these protocols, aiming to reduce the doses to patients.

    Full Text Available Acute portomesenteric venous thrombosis is a rare but life-threatening complication of laparoscopic surgery that has been described in literature. Prompt diagnosis and early initiation of treatment are vital to prevent life-threatening complications such as mesenteric ischemia and infarction. A 51-year-old lady had laparoscopic small bowel resection and primary anastomosis with ventral hernia repair 4 weeks earlier for partial small bowel obstruction. Her postoperative period was uneventful and she was discharged home. Four weeks after surgery she developed watery diarrhea and generalized abdominal pain for four-day duration. A computed tomography of the abdomen revealed portomesenteric venous thrombosis although a computed tomography of abdomen before surgery 4 weeks back did not show any portomesenteric venous thrombosis. We are reporting a case of acute portomesenteric venous thrombosis as a complication of laparoscopic surgery.

    2015-09-01

    Porphyrias are a group of eight metabolic disorders characterized by defects in heme biosynthesis. Porphyrias are classified into two major categories: 1) the acute or inducible porphyrias and 2) the chronic cutaneous porphyrias. The acute hepatic porphyrias are further classified into acute intermittent porphyria (AIP), hereditary coproporphyria, variegate porphyria, and porphyria due to severe deficiency of delta-aminolevulinic acid (ALA) dehydratase (ALADP). AIP is the most common, and ALADP is the least common acute porphyria. The clinical presentations of acute porphyrias are nonspecific. There are no pathognomonic signs or symptoms. The most frequent presenting symptom is abdominal pain, but pain in the chest, back, or lower extremities may also occur. Hyponatremia is the most common electrolyte abnormality during acute attacks, and hypomagnesemia is also common. Both are risk factors for development of seizures, which occur in ∼ 20-30% of acute attacks. Once suspected, the diagnosis of porphyria can be rapidly established by checking random urinary porphobilinogen. Initial management of acute porphyria includes discontinuation of all potentially harmful drugs and management of symptoms. Acute attacks should be treated emergently with intravenous heme and glucose to avoid considerable morbidity and mortality. Acute attacks last a few days, and the majority of patients are asymptomatic between attacks. Prognosis is good if the condition is recognized early and treated aggressively.

    Full Text Available Introduction. A patent urachus is a rare congenital or acquired pathology, which can lead to complications later in life. We describe a case of urachal cystitis as the etiology of small bowel obstruction in an adult without prior intra-abdominal surgery. Case Report. A 64-year-old male presented to the acute care surgery team with a 5-day history of right lower quadrant abdominal pain, distention, nausea, and vomiting. He had a two-month history of urinary retention and his past medical history was significant for benign prostate hyperplasia. On exam, he had evidence of small bowel obstruction. Computed tomography revealed high-grade small bowel obstruction secondary to presumed ruptured appendicitis. In the operating room, an infected urachal cyst was identified with adhesions to the proximal ileum. After lysis of adhesions and resection of the cyst, the patient was subsequently discharged without further issues. Conclusion. Although rare, urachal pathology should be considered in the differential diagnosis when evaluating a patient with small bowel obstruction without prior intraabdominal surgery, hernia, or malignancy.

    After studying two rural communities with varing endemicity of urinary schistosomiasis by total cross-sectional population survey, a stratified sample was obtained using defined criteria. Plain X-ray abdomen and intravenous pyelogram were carried out on the sample. Findings on plain X-ray of the abdomen, using the usual parameters of psoas and kidney shadows in the Nigerian, indicate that the two communities studied are similar but urinary calculi and urinary tract distortion are significantly more prominent in the community with the higher endemicity of urinary schistosomiasis.

    Mutilating injury on pelvis may be complicated by urinary bladder ruptures and soft-tissue avulsion of the lower abdominal wall or perineum. With retraction of the avulsed abdominal wall or perineum, as well as bladder tissue loss secondary to trauma or infection, direct closure the injured bladder often leads to excessive tension, resulting in ischemia and eventual failure of repair. The authors successfully managed 4 patients with such injuries using the pedicled vastus lateralis myocutaneous flap. No major complications occurred and intact bladders were confirmed with cystograms. Three (75%) of them were able to void normally within 1 year. It is concluded that the pedicled vastus lateralis myocutaneous flap is an ideal option for posttraumatic bladder reconstruction and soft-tissue coverage of the lower abdomen or perineum; whereas the undersurface of the muscle serves as a substitute for the missing bladder wall, the remaining part of the muscle, as well as the subcutaneous fat, provide sufficient bulk for dead space obliteration.

    Purpose: The aim of this work was to reduce the influence of motion on diffusion-weighted MR images of the abdomen by pulse triggering of single-shot sequences. Methods: Five healthy volunteers were examined both without and with finger pulse-triggering of a diffusion-weighted single-shot echo planar MR imaging sequence at 1.5 T. Series of diffusion-weighted images were acquired at different phases of the cardiac cycle by varying the time delay between finger pulse and sequence acquisition. The measurements were repeated three times. The diffusion weighted images were analysed by measuring the signal intensities and by determining the ADC values within the spleen, kidney and liver. Results: The magnitude of motion artifacts on diffusion weighted images shows a strong dependence on the trigger delay. The optimum trigger delay is found to be between 500 and 600 ms. For these values the abdominal organs appear homogeneous on all diffusion weighted images and the strongest signal intensities are detected. At optimum triggering the accuracy of the apparent diffusion coefficients is up to 10 times better than without triggering. Moreover, the standard deviation of the repeated measurements is smaller than 12% for all volunteers and for all organs. Without triggering the standard deviation is larger by a factor of 4 on average. Conclusion: Pulse triggering of single-shot sequences leads to significant reduction of motion related artifacts on diffusion weighted images of the abdomen and provides more accurate and reproducible ADC values.

    Full Text Available Introduction: Our clinical experience showed that there has been no decrease in pediatric cases of acute viral hepatitis in Kathmandu. The objective of the study was to analyze the etiology, clinical features, laboratory parameters, sonological findings and other to determine the probable prognostic factors of Acute Viral Hepatitis in pediatric population. Methods: Consecutive patients of suspected Acute Viral Hepatitis, below the age of 15 years, attending the liver clinic between January 2006 and December2010were studied. After clinical examination they were subjected to blood tests and ultrasound examination of abdomen. The patients were divided in 3 age groups; 0–5, 5–10 and 5–15 years. Clinical features, laboratory parameters, ultrasound findings were compared in three age groups. Results: Etiology of Acute Viral Hepatitis was Hepatitis A virus 266 (85%, Hepatitis E virus in 24 (8%, Hepatitis B virus in 15 (5%. In 7(2% patients etiology was unknown. Three patients went to acute liver failure but improved with conservative treatment. There was no statistical difference in most of the parameters studied in different age groups. Ascites was more common in 5-10 years age group. Patients with secondary bacterial infection, ultrasound evidence of prominent biliary tree and ascites were associated with increased duration of illness. Patients with history of herbal medications had prolonged cholestasis. Conclusions: Hepatitis A is most common cause of Acute Viral Hepatitis in pediatric population. Improper use of herbal medications, secondary bacterial infection and faulty dietary intake was associated with prolonged illness. Patients with prominent biliary radicals should be treated with antibiotics even with normal blood counts for earlier recovery.

    To highlight the problems of diagnosis and management of acute abdomen in patients with lassa fever. And to also highlight the need for high index of suspicion of lassa fever in patients presenting with acute abdominal pain in order to avoid surgical intervention with unfavourable prognosis and nosocomial transmission of infections, especially in Lassa fever-endemic regions. A review of experiences of the authors in the management of lassa fever over a 4-year period (2004-2008). Literature on lassa fever, available in the internet and other local sources, was studied in November 2010 and reviewed. Normal plain chest radiographic picture can change rapidly due to pulmonary oedema, pulmonary haemorrhage and acute respiratory distress syndrome. Plain abdominal radiograph may show dilated bowels with signs of paralytic ileus or dynamic intestinal obstruction due to bowel wall haemorrhage or inflamed and enlarged Peyer's patches. Ultrasound may show free intra-peritoneal fluid due to peritonitis and intra-peritoneal haemorrhage. Bleeding into the gall bladder wall may erroneously suggest infective cholecystitis. Pericardial effusion with or without pericarditis causing abdominal pain may be seen using echocardiography. High index of suspicion, antibody testing for lassa fever and viral isolation in a reference laboratory are critical for accurate diagnosis. Patients from lassa fever-endemic regions may present with features that suggest acute abdomen. Radiological studies may show findings that suggest acute abdomen but these should be interpreted in the light of the general clinical condition of the patient. It is necessary to know that acute abdominal pain and vomiting in lassa fever-endemic areas could be caused by lassa fever, which is a medical condition. Surgical option should be undertaken with restraint as it increases the morbidity, may worsen the prognosis and increase the risk of nosocomial transmission.

    Ecchymosis and/or haematoma are the most common adverse events after subcutaneous administration of low molecular weight heparin. There is no strong recommendation as to the puncture site. To evaluate the adverse events, ecchymosis and/or haematoma after the administration of prophylactic subcutaneous enoxaparin in the abdomen vs the arm in the critically ill patient. A randomised, two-arm clinical trial (injection in the abdomen vs the arm), performed between July 2014 and January 2017, in an 18-bed, polyvalent intensive care unit. Patients receiving prophylactic enoxaparin, admitted >72h, with no liver or haematological disorders, a body mass index (BMI) >18.5, not pregnant, of legal age and with no skin lesions which would impede assessment were included. We excluded patients who died or who were transferred to another hospital before completing the evaluation. We gathered demographic and clinical variables, and the onset of ecchymosis and/or haematomas at the injection site after 12, 24, 48 and 72hours. A descriptive analysis was undertaken, with group comparison and logistic regression. The study was approved by the ethics committee with the signed consent of patients/families. 301 cases (11 excluded): 149 were injected in the abdomen vs 141 in the arm. There were no significant differences in demographic and clinical variables, BMI, enoxaparin dose or antiplatelet administration [ecchymosis, abdomen vs arm, n(%): 66(44) vs 72(51), P=.25] [haematoma abdomen vs arm, n(%): 9(6) vs 14(10), P=.2]. Statistical significance was found in the size of the haematomas after 72h: [area of haematoma (mm 2 ) abdomen vs arm, median (IQR): 2(1-5.25) vs 20(5.25-156), P=.027]. In our patient cohort, prophylactic subcutaneous enoxaparin administered in the abdomen causes fewer haematomas after 72hours, than when administered in the arm. The incidence rate of ecchymosis and haematoma was lower than the published incidence in critically ill patients, although patients receiving

    The open abdomen technique is a standard procedure in the treatment of intra-abdominal catastrophe. Achieving primary abdominal closure within the initial hospitalization is a main objective. This study aimed to analyze the success of closure rate and the effect of negative pressure wound therapy, mesh-mediated medial traction, and component separation on the results. We present the treatment algorithm used in our institution in open abdomen situations based on these findings. Open abdomen patients (n = 61) treated in Tampere University Hospital from May 2005 until October 2013 were included in the study. Patient characteristics, treatment prior to closure, closure technique, and results were retrospectively collected and analyzed. The first group included patients in whom direct or bridged fascial closure was achieved, and the second group included those in whom only the skin was closed or a free skin graft was used. Background variables and variables related to surgery were compared between groups. Most of the open abdomen patients (72.1%) underwent fascial defect repair during the primary hospitalization, and 70.5% of them underwent direct fascial closure. Negative pressure wound therapy was used as a temporary closure method for 86.9% of the patients. Negative pressure wound therapy combined with mesh-mediated medial traction resulted in the shortest open abdomen time (p = 0.039) and the highest fascial repair rate (p = 0.000) compared to negative pressure wound therapy only or no negative pressure wound therapy. The component separation technique was used for 11 patients; direct fascial closure was achieved in 5 and fascial repair by bridging the defect with mesh was achieved in 6. A total of 8 of 37 (21.6%) patients with mesh repair had a mesh infection. The negative pressure wound therapy combined with mesh-mediated medial traction promotes definitive fascial closure with a high closure rate and a shortened open abdomen time. The component

    This work had the objective to achieve the knowledge of the dosimetric quantities related to chest and abdomen computed tomography (CT) examinations of pediatric patients, in Belo Horizonte city. The reason of this work is based on the fact that the probability of health detriment in children, which it may be caused by radiation, is higher than in adults. Besides, although in many countries the knowledge and control of patient doses is a normal procedure, this safety culture does not exist in Brazil. Another objective of this work was to compare the dosimetric quantity values with the Diagnostic Reference Levels (DRLs); when it was needed, an optimization process was applied and the quality of the diagnostic image obtained with the optimized technical parameters was analyzed. This study was carried out in five hospitals, where the weighted air kerma index (Cw), the volumetric air kerma index (Cvol), the air kerma - length product (PKL,CT), the Effective Dose (E) and the Normalized Effective Dose (En) were determined; three methods were adopted for measurements: the ionization chamber inside a chest pediatric phantom, radiochromic films and the CT-EXPO software. The optimization process was applied to a single hospital through variations in the current (mA) and voltage (kV) of the x-ray tube for the protocols used for abdomen CT examinations. The analysis of the quality of the diagnostic image was done by Normal Distribution and ROC analysis; spatial resolution analysis was used through MTF determination and the noise level was judged in terms quantitative and qualitative. Results of the dosimetric quantities showed that they significantly differed between single-slice and multi-slice tomography units, but their values were always below the recommended DRLs. The optimized values of the dosimetric quantities obtained after the optimization process showed that it was possible to reduce the radiation exposure of pediatric patient without losing the image quality

    Proper management of abdominal compartment syndrome and open abdomen is important for improving the survival of critically ill patients. However, in cases requiring a prolonged period of open abdomen, it is frequently difficult to perform definitive fascial closure due to lateralization of the abdominal musculature. We herein present a novel combined technique for managing open abdomen. A 74-year-old male with diffuse peritonitis was transferred to our department, after which a long period of open abdomen made it difficult to achieve fascial closure. Polypropylene mesh was sutured to the fascial edges to reduce the gap, which was then serially tightened under negative pressure wound therapy. However, since it was not possible to accomplish definitive fascial closure, abdominal closure was performed using the bilateral anterior rectus abdominis sheath turnover flap method after removing the mesh, without any complications. This combined technique may be an effective alternative in patients requiring open abdomen with subsequent difficulty in achieving definitive fascial closure.

CASES AND APPROACHES: During the period 1998-2008 56 patients were hospitalized (31 women and 25 men) at the Surgical department of the University hospital "Alexandrovska". They had different forms of colonic diverticulosis. The average age of the patients was 66.7. The retrospective analysis divides the patients into three clinical groups: 1st group--peritonitis and pericolic abscess caused by diverticulosis--present in 49 patients. 2nd group--chronic non-specific inflammatory infiltrate and fistula--present in 5 patients. 3rd group--severe haemorrhage and anaemic syndrome--present in 2 patients Mortality-rate is 12.5% (7 patients). 10 patients with complications were registered--5 with suppuration of the surgical wound and 5 with pneumonia and pleural effusion. Colonic diverticulosis is a disease of great surgical interest because of its complicated forms requiring conventional or surgical treatment. Various forms of peritonitis which are part of the emergency surgical abdomen domain are relatively frequent complication of the gastrointestinal (in particular of the colon) diverticulosis. They are difficult to diagnose in the pre-operative period and its not easy to take a decision about the particular operative approach. All that is related with the relatively high morbidity and mortality.

    The radiation protection has recently gained considerable attention in human medicine. In veterinary medicine has been some advances in radiodiagnostic and therapy for domestic animal like dogs and cats. It is notable the increase of the costs with domestic animals that are considered, by many people in the whole world, like members of family. However, an important parameter that must be taken into account is the increasing use of computed tomography and other equipment s that uses ionizing radiation, which may lead to comparatively high exposure of critical organs. The radiation dose is determined by the balance between therapeutic benefit and possible damage to surrounding normal tissues. This study aimed the evaluation of entrance surface-skin doses in dogs submitted to radiodiagnostic procedures of abdomen using the technique of thermoluminescent dosimetry (TLD). The radiation doses were measured using thermoluminescent dosimeters of LiF:Mg,Ti (TLD 100) and a dog phantom made with a plastic container, proportional to the dog size, fulfilled with water.

    Reports of catastrophic neurologic injuries following lumbar transforaminal epidural steroid injections are rare but serious potential complications. The traditional method of performing lumbar transforaminal epidural steroid injections is in the "safe triangle" to avoid contact to the spinal nerve. Some authors advocate an alternative approach by placing the needle inferiorly in a region referred to as "Kambin's triangle" to avoid incurring arteries. This study aimed to determine the location of arteries within the L1-L4 intervertebral foramen in vivo, specifically if they lie within or in close proximity to the "safe triangle" or Kambin's triangle using CT angiograms of the abdomen and pelvis. The authors retrospectively evaluated the location in vivo of arterial vessels in the intervertebral foramen from L1 to L4 in patients who underwent abdominopelvic CT angiograms for aortic vascular disease. The data were reanalyzed to confirm inter-rater reliability. Arteries were found in both the safe triangle and Kambin's triangle at a statistically significant rate (P triangle or in Kambin's triangle frequently, suggesting the location of these arteries can be quite variable. Physicians performing these procedures should use universal precautions to avoid inadvertent injection into the lumbar spinal arteries and minimize potential complications regardless of the approach.

    Significant percentage of today's knowledge of ancient Egyptian medicine has been acquired from papyri left behind from various periods of Egyptian history. The longest and the most comprehensive is the Ebers papyrus, kept at the University Museum of Leipzig, which was written more than one thousand years before Hippocrates (c. 460-377 BC). One of the riddles among the prescriptions of the Ebers papyrus Eb20 has been used in order to remove the so called "wemyt" weremit from the abdomen with the help of a drink, which consists of "jnnk", Conyza dioscoridis in milk or sweet beer. The authors assume that the disease could be an infection of Schistosoma haematobium and/or Schistosoma mansoni. Nowadays the tea of Conyza dioscoridis is widely used as an important part of traditional medicine against rheumatism, intestinal distention and cramps, as well as an antiperspirant, and with external use for wound healing. The authors' intent is to interpret the efficacy of the above-mentioned ancient prescription with the help of modern medical and pharmaceutical knowledge.

    This study investigated the alleviating effects of aromatherapy massage and acetaminophen on menstrual pain in Korean high school girls. Subjects were divided into two groups: the aromatherapy massage (treatment) group (n = 32) and the acetaminophen (control) group (n = 23). Aromatherapy massage was performed on subjects in the treatment group. The abdomen was massaged once using clary sage, marjoram, cinnamon, ginger, and geranium in a base of almond oil. The level of menstrual pain was assessed using a visual analogue scale at baseline and twenty-four hours afterward. The reduction of menstrual pain was significantly higher in the aromatherapy group than in the acetaminophen group. Using multiple regression, aromatherapy massage was found to be more highly associated with reduction in the level of menstrual pain than acetaminophen. These finding suggest that aromatherapy massage may be an effective treatment for menstrual pain in high school girls. However, it could not be verified whether the positive effects derived from the aromatherapy, the massage, or both. Further rigorous studies should be conducted using more objective measures.

    In order to provide a precise radiography for diagnosis, it is required that we avoid radiography with defects by having enough evaluation. Conventionally, evaluation was performed only by observation of a radiological technologist (RT). The evaluation support system was developed for providing a high quality assurance without depending on RT observation only. The evaluation support system, called as the Image Quality Assurance Support System (IQASS), is characterized in that "image recognition technology" for the purpose of diagnostic radiography of chest and abdomen areas. The technique of the system used in this study. Of the 259 samples of posterior-anterior (AP) chest, lateral chest, and upright abdominal x-rays, the sensitivity and specificity was 93.1% and 91.8% in the chest AP, 93.3% and 93.6% in the chest lateral, and 95.0% and 93.8% in the upright abdominal x-rays. In the light of these results, it is suggested that AIQAS could be applied to practical usage for the RT.

    Computed tomographic (CT) scanning is increasingly prevalent in emergency departments (EDs). It is a moderate- to high-radiation diagnostic technique that exposes more than 1 million children per year to unnecessary radiation. Repeat CT of the abdomen and pelvis (CTAP) among pediatric patients who return to the ED within 1 year may be an example of unnecessary pediatric radiation exposure. The objectives of this study were to identify the incidence of pediatric patients who undergo more than 1 CTAP within 1 year and to detect the incidence of significant pathology on these repeat scans. This was a retrospective review of subjects younger than 18 years with an initial CTAP as an ED patient, inpatient, or outpatient and a second CTAP within 12 months and during an ED visit. During the observation period, 172 pediatric ED admissions had at least 1 repeat admission involving an abdominal CT scan. Thirty-seven of the CT scans (19.3%) were positive. Sixty percent of the positive cases (n = 22) were attributable to the 3 most prevalent diagnoses: appendicitis in 8 cases (21.6%), kidney stone in 8 cases (21.6%), and colitis in 6 cases (16.2%). Approximately, one third of repeat CT scans occurred within the first month of the initial CT scan, and two thirds occurred within 6 months of the initial CT scan. A substantial percentage of pediatric patients undergo more than 1 CTAP within a 1-year time frame. Among these patients, a large portion were diagnosed significant pathology.

    To demonstrate the technical feasibility and the potential interest of using a digital optical camera inside the MR magnet bore for monitoring the breathing cycle and subsequently gating the PRFS MR thermometry, MR-ARFI measurement, and MRgHIFU sonication in the upper abdomen. A digital camera was reengineered to remove its magnetic parts and was further equipped with a 7 m long USB cable. The system was electromagnetically shielded and operated inside the bore of a closed 3T clinical scanner. Suitable triggers were generated based on real-time motion analysis of the images produced by the camera (resolution 640 × 480 pixels, 30 fps). Respiratory-gated MR-ARFI prepared MRgHIFU ablation was performed in the kidney and liver of two sheep in vivo, under general anaesthesia and ventilator-driven forced breathing. The optical device demonstrated very good MR compatibility. The current setup permitted the acquisition of motion artefact-free and high resolution MR 2D ARFI and multiplanar interleaved PRFS thermometry (average SNR 30 in liver and 56 in kidney). Microscopic histology indicated precise focal lesions with sharply delineated margins following the respiratory-gated HIFU sonications. The proof-of-concept for respiratory motion management in MRgHIFU using an in-bore digital camera has been validated in vivo.

    Open abdomen (OA) treatment is sometimes necessary after surgery for aortic aneurysm (AA), to prevent or treat abdominal compartment syndrome (ACS). A multicentre study evaluating vacuum-assisted wound closure (100-150 mmHg) and mesh-mediated fascial traction (VAWCM) was performed. All patients treated with OA after AA repair (2006-2009) were prospectively registered at four centres; those treated closure; primary delayed fascial closure was achieved in all survivors. One-year mortality was 50%. Ten (33%) had bowel ischaemia requiring bowel resection. Late potential OA-related infectious complications occurred in five (17%), all of whom first developed intestinal ischaemia: entero-atmospheric fistulae (two), graft infections (two), aorto-enteric fistula (one). One year follow-up with clinical evaluation and CT showed no signs of graft infection. Incisional hernias occurred in 9 of 15 patients (60%); only three were symptomatic. VAWCM provided high fascial closure rate after AA repair and long-term OA treatment. Infectious complications occur after intestinal ischaemia and prolonged OA treatment, and are often fatal. The poor prognosis among patients needing OA after AA surgery may be improved by using VAWCM, permitting earlier closure. Copyright © 2013 European Society for Vascular Surgery.

Se revisaron las historias clínicas de 97 pacientes portadores del VIH que cursaron con un cuadro de AA y que fueron atendidos en el período 2006-2011 en el Hospital Nacional Cayetano Heredia en Lima, Perú. Se encontró que el 1,6% de los pacientes inmunosuprimidos ingresó a sala de operaciones. La apendicectomía fue el procedimiento quirúrgico más frecuentemente (33,3%. La morbilidad fue de 28,1%, y la mortalidad posoperatoria de 9,4%. La infección por Mycobacterium tuberculosis fue la causa más común de dolor abdominal agudo con el 26,8%. Los datos sugieren que una pronta decisión quirúrgica frente a un cuadro compatible con AA en pacientes con VIH podría evitar una importante morbimortalidad.

    The paper presents 44 cases of small intestine perforation caused by blunt abdominal trauma in a period of 12 years. 34 patients were men and 10 were women. The patients were aged from 10 to 82 years which gives an average age of 39 years. The average incidence of cases was 4 per year. In 23 patients associated injuries were diagnosed, namely: 5 spleen ruptures, 3 liver ruptures, 5 colon perforations, 1 pancreas injury and 1 kidney injury. Associated injuries in which the dominant syndrome was intraabdominal hemorrhage presented no diagnostical difficulties seeing that the results of punction or abdomen lavage indicated immediate laparotomy. In patients with isolated injury of the small intestine and clinical signs of peritonitis laparotomy was treated with a two layer suture in 32 patients; in 12 patients resection with T-T or L-L anastomosis was made. Associated injuries were treated in the same act. Of 44 patients treated in our Clinic 37 were treated successfully, while 7 died.

  10. The Narrow Abdomen Ion Channel Complex Is Highly Stable and Persists from Development into Adult Stages to Promote Behavioral Rhythmicity

    Full Text Available The sodium leak channel NARROW ABDOMEN (NA/ NALCN is an important component of circadian pacemaker neuronal output. In Drosophila, rhythmic expression of the NA channel regulator Nlf-1 in a subset of adult pacemaker neurons has been proposed to contribute to circadian regulation of channel localization or activity. Here we have restricted expression of Drosophila NA channel subunits or the Nlf-1 regulator to either development or adulthood using the temperature-inducible tubulin-GAL80ts system. Surprisingly, we find that developmental expression of endogenous channel subunits and Nlf-1 is sufficient to promote robust rhythmic behavior in adults. Moreover, we find that channel complex proteins produced during development persist in the Drosophila head with little decay for at least 5–7 days in adults. In contrast, restricting either endogenous or transgenic gene expression to adult stages produces only limited amounts of the functional channel complex. These data indicate that much of the NA channel complex that functions in adult circadian neurons is normally produced during development, and that the channel complex is very stable in most neurons in the Drosophila brain. Based on these findings, we propose that circadian regulation of NA channel function in adult pacemaker neurons is mediated primarily by post-translational mechanisms that are independent of Nlf-1.

    Objectives of this study were to compare radial time-resolved phase contrast magnetic resonance imaging (4D Flow-MRI) with perivascular ultrasound (pvUS) and to explore a porcine model of acute pre-hepatic portal hypertension (PHTN). Abdominal 4D Flow-MRI and pvUS in portal and splenic vein, hepatic and both renal arteries were performed in 13 pigs of approximately 60 kg. In six pigs, measurements were repeated after partial portal vein (PV) ligature. Inter- and intra-reader comparisons and statistical analysis including Bland-Altman (BA) comparison, paired Student's t tests and linear regression were performed. PvUS and 4D Flow-MRI measurements agreed well; flow before partial PV ligature was 322 ± 30 ml/min in pvUS and 297 ± 27 ml/min in MRI (p = 0.294), and average BA difference was 25 ml/min [-322; 372]. Inter- and intra-reader results differed very little, revealed excellent correlation (R 2 = 0.98 and 0.99, respectively) and resulted in BA differences of -5 ml/min [-161; 150] and -2 ml/min [-28; 25], respectively. After PV ligature, PV flow decreased from 356 ± 50 to 298 ± 61 ml/min (p = 0.02), and hepatic arterial flow increased from 277 ± 36 to 331 ± 65 ml/min (p = n.s.). The successful in vivo comparison of radial 4D Flow-MRI to perivascular ultrasound revealed good agreement of abdominal blood flow although with considerable spread of results. A model of pre-hepatic PHTN was successfully introduced and acute responses monitored. • Radial 4D Flow-MRI in the abdomen was successfully compared to perivascular ultrasound. • Inter- and intra-reader testing demonstrated excellent reproducibility of upper abdominal 4D Flow-MRI. • A porcine model of acute pre-hepatic portal hypertension was successfully introduced. • 4D Flow-MRI successfully monitored acute changes in a model of portal hypertension.

    Acute appendiceal diverticulitis is an unusual cause of acute abdomen, considered clinically indistinguishable from acute appendicitis. In a historic cohort study with 27 cases of appendiceal diverticulitis and 54 cases of acute appendicitis, we compared clinical characteristics, diagnostic tests and pathology findings of the two processes. Mean age at presentation was lower in acute appendicitis (37.24 +/- 19.98 vs. 54.81 +/- 17.55 years, p diverticulitis group, 48.15 % had leukocytosis vs. 81.48 % in the appendicitis group (p = 0.02); there was no difference in leukocyte count (13770.37 +/- 4382.55 vs. 14279.63 +/- 4268.59, p = 0.61). Patients with appendiceal diverticulitis had a higher incidence of appendiceal mucocele (p = 0.01) and a lower proportion of appendiceal gangrene (p = 0.03). There were no differences in appendiceal perforation or ulceration. Symptom duration before emergency department attendance (71.61 +/- 85.25 hours vs. 36.84 +/- 33.59 hours; Z = -3.1 p = 0.002), duration of surgery (85 +/- 40 minutes vs. 60 +/- 21 minutes, Z = -3.2, p = 0.001) and the presence of appendicular plastron was higher in patients with diverticulitis vs. appendicitis (8 vs. 5 patients [p = 0.01, Odds ratio 2.2]). Appendiceal diverticulitis presents a series of clinical, epidemiological and pathological differences with respect to acute appendicitis. The former shows a more indolent course with delayed diagnosis.

It is characterized by a purulent inflammation that can affect the entire gastrointestinal tract and presents a high mortality rate. We are reporting a case of phlegmonous gastritis in an HIV-seropositive man successfully treated with antibiotics. Moreover, a review of the English and Spanish literature is carried out, from 1980 to the present time. The most frequently involved microorganism is Streptococcus spp. (57 %, but the polimicrobial infection is also frequent (17 %. The most important symptom is the intensive epigastric pain associated with vomits and most cases were diagnosed by CT and/or fibrogastroscopy. There are many existing risk factors described. The main one is the immunesuppression, although in 40 % of the cases no risk factors were identified. The global mortality is 27 % without identifying significant differences between antibiotics and surgical treatment, for that reason it is recommended to initiate antibiotic treatment right from the beginning and postponing surgery for the refractory cases and complications.

    Ovarian vein thrombosis is a known complication in the peri- and postpartum phase. Its incidence is documented as 1:600 to 1:2000. Concerning ovarian vein thrombosis in earlier stages of pregnancy there are only very few case reports. We report on a woman in her third pregnancy who presented with acute abdominal pain in the 27th week of gestation. After a long car drive she felt an acute pain in the upper right abdomen which moved down to the right lower abdomen. On admission the obstetrical examination showed no pathology. There were no contractions. Clinical and sonographic examination could not reveal the cause of the pain. As adequate analgesia failed to relieve the pain, an explorative laparotomy was performed. It showed a dilated right ovarian vein of 3 cm diameter with a thrombus reaching the confluence to the vena cava. The ovarian vessels were resected and the adnectomy on the right side performed. Anticoagulation was initiated. There were no complications during the postoperative course. The pregnancy proceeded normally. After 10 days the patient could be dismissed in good condition. Laboratory diagnostic showed an deficiency in protein C. At 39 weeks of gestation a planned caesarean section was performed without any complications.

    The first objective of the study was to determine the thorax and abdomen deflection time corridors using the equal stress equal velocity approach from oblique side impact sled tests with postmortem human surrogates fitted with chestbands. The second purpose of the study was to generate deflection time corridors using impulse momentum methods and determine which of these methods best suits the data. An anthropometry-specific load wall was used. Individual surrogate responses were normalized to standard midsize male anthropometry. Corridors from the equal stress equal velocity approach were very similar to those from impulse momentum methods, thus either method can be used for this data. Present mean and plus/minus one standard deviation abdomen and thorax deflection time corridors can be used to evaluate dummies and validate complex human body finite element models.

    A 23-year-old male with a history of bone marrow transplant for acute myeloid leukemia. He presented a large mass in the right inguinal region 5 years ago. Upon physical examination, right-sided cryptorchidism was observed. The tumor markers alpha-fetoprotein and beta-HCG were within normalcy range and lactate dehydrogenase was raised. Computed tomography of the abdomen and pelvis revealed right testicular mass in contiguity with the inguinal canal to the ipsilateral retroperitoneum, associated with right hydronephrosis. Due to the risk of germ-cell tumor in undescended testicle, the patient underwent radical right orchiectomy. The pathological examination showed recurrence of acute myeloid leukemia in the testis. He was referred to oncology for adjuvant therapy. Our literature review found no similar cases described.

    Breast cancer has high metastatic potential with distant metastases involving mainly lungs, liver and bones. Less frequently it gives distant spread to other organs. Herein we would like to present a very rare case of an acute cholecystitis which turned out to be a metastatic breast cancer in previously healthy woman. A female patient, 64-years old, presented to the emergency department with symptoms of biliary colic and acute abdomen. During the emergency cholecystectomy, we diagnosed the gallbladder empyema with thickened wall. There were also multiple metastatic nodules in the peritoneal cavity and an excessive amount of free fluid. The emergency physicians diagnosing female patient with the acute abdominal symptoms and a breast cancer history might suspect malignant spread into abdominal organs including gallbladder. On the other hand, acute cholecystitis symptoms might be the first symptoms of metastatic process in the gallbladder from the unknown primary source, which may be breast.

    Full Text Available Abstract Background The acute abdomen is a frequent entity at the Emergency Department (ED, which usually needs rapid and accurate diagnostic work-up. Diagnostic work-up with imaging can consist of plain X-ray, ultrasonography (US, computed tomography (CT and even diagnostic laparoscopy. However, no evidence-based guidelines exist in current literature. The actual diagnostic work-up of a patient with acute abdominal pain presenting to the ED varies greatly between hospitals and physicians. The OPTIMA study was designed to provide the evidence base for constructing an optimal diagnostic imaging guideline for patients with acute abdominal pain at the ED. Methods/design Thousand consecutive patients with abdominal pain > 2 hours and Discussion This study aims to provide the evidence base for the development of a diagnostic algorithm that can act as a guideline for ED physicians to evaluate patients with acute abdominal pain.

    Open abdomen management has become a well-established strategy in the treatment of serious intra-abdominal pathologies. Key objectives are fistula prevention and high fascial closure rates. The current level of evidence on laparostoma is insufficient. This is due to the rareness of laparostomas, the heterogeneity of study cohorts, and broad diversity of techniques. Collecting data in a standardised, multicentre registry is necessary to draw up evidence-based guidelines. In order to improve the level of evidence on laparostomy, CAMIN (surgical working group for military and emergency surgery) of DGAV (German Society for General and Visceral Surgery), initiated the implementation of a laparostomy registry. This registry was established as the Open Abdomen Route by EuraHS (European Registry of Abdominal Wall Hernias). Key objectives include collection of data, quality assurance, standardisation of therapeutic concepts and the development of guidelines. Since 1 May 2015, the registry is available as an online database called Open Abdomen Route of EuraHS (European Registry of Abdominal Wall Hernias). It includes 11 categories for data collection, including three scheduled follow-up examinations. As part of this pilot study, all entries of the first 120 days were analysed, resulting in a review of 82 patients. At 44%, secondary peritonitis was the predominant indication. The mortality rate was 22%. A comparison of methods with and without fascial traction reveals fascial closure rates of 67% and 25%, respectively (intention-to-treat analysis, p high fascial closure rates is possible. The method that ensures the best possible outcome-based on current evidence-would involve fascial traction, visceral protection and negative pressure. The laparostomy registry is a useful tool for quickly generating sufficient evidence for open abdomen treatment.

    Unprovoked venous thromboembolism (VTE) can be the first manifestation of cancer. It is unclear if extensive screening for occult cancer including a comprehensive computed tomography (CT) scan of the abdomen/pelvis is cost-effective in this patient population. To assess the health care related costs, number of missed cancer cases and health related utility values of a limited screening strategy with and without the addition of a comprehensive CT scan of the abdomen/pelvis and to identify to what extent testing should be done in these circumstances to allow early detection of occult cancers. Cost effectiveness analysis using data that was collected alongside the SOME randomized controlled trial which compared an extensive occult cancer screening including a CT of the abdomen/pelvis to a more limited screening strategy in patients with a first unprovoked VTE, was used for the current analyses. Analyses were conducted with a one-year time horizon from a Canadian health care perspective. Primary analysis was based on complete cases, with sensitivity analysis using appropriate multiple imputation methods to account for missing data. Data from a total of 854 patients with a first unprovoked VTE were included in these analyses. The addition of a comprehensive CT scan was associated with higher costs ($551 CDN) with no improvement in utility values or number of missed cancers. Results were consistent when adopting multiple imputation methods. The addition of a comprehensive CT scan of the abdomen/pelvis for the screening of occult cancer in patients with unprovoked VTE is not cost effective, as it is both more costly and not more effective in detecting occult cancer.

    To assess the benefit and limits of iterative reconstruction of paediatric chest and abdominal computed tomography (CT). The study compared adaptive statistical iterative reconstruction (ASIR) with filtered back projection (FBP) on 64-channel MDCT. A phantom study was first performed using variable tube potential, tube current and ASIR settings. The assessed image quality indices were the signal-to-noise ratio (SNR), the noise power spectrum, low contrast detectability (LCD) and spatial resolution. A clinical retrospective study of 26 children (M:F = 14/12, mean age: 4 years, range: 1-9 years) was secondarily performed allowing comparison of 18 chest and 14 abdominal CT pairs, one with a routine CT dose and FBP reconstruction, and the other with 30 % lower dose and 40 % ASIR reconstruction. Two radiologists independently compared the images for overall image quality, noise, sharpness and artefacts, and measured image noise. The phantom study demonstrated a significant increase in SNR without impairment of the LCD or spatial resolution, except for tube current values below 30-50 mA. On clinical images, no significant difference was observed between FBP and reduced dose ASIR images. Iterative reconstruction allows at least 30 % dose reduction in paediatric chest and abdominal CT, without impairment of image quality. • Iterative reconstruction helps lower radiation exposure levels in children undergoing CT. • Adaptive statistical iterative reconstruction (ASIR) significantly increases SNR without impairing spatial resolution. • For abdomen and chest CT, ASIR allows at least a 30 % dose reduction.

    Failure to definitively close the open abdomen (OA) after damage control laparotomy leads to considerable morbidity and mortality. We have developed a novel technique, the "chemical components separation," which incorporates injection of botulinum toxin A (BTX), a long-term flaccid paralytic, into the lateral abdominal wall musculature. This is a retrospective review of all OA patients (age ≥18) from December 2009-June 2010 who underwent BTX injection. Under ultrasound guidance, a total of 300 units of BTX were injected into the external oblique, internal oblique and transversus abdominus. A total of 18 patients were injected with a median age of 66 years (56 % male). Indications for OA treatment included questionable bowel viability (39 %), shock (33 %), loss of abdominal domain (6 %) and feculent contamination (17 %). Median ASA score was 3 with an APACHE 3 score of 85. Patients underwent a median of 4 serial abdominal explorations. The primary fascial closure rate was 83 % with a partial fascial closure rate of 6 % and planned ventral hernia rate of 11 %. Of the 9 patients injected within 24 h of their initial OA procedure, 89 % achieved primary fascial closure. Mortality was 11 %; death was unrelated to BTX injection. The overall complication rate was 67 %; specific complications rates included fascial dehiscence (11 %), enterocutaneous fistula development (0 %), intra-abdominal abscess (44 %) and deep surgical site infection (33 %). The "chemical components separation" technique described is safe and avoids the extensive dissection necessary for mechanical components separation in critically ill patients with infected/contaminated abdominal domains. While further evaluation is required, the described technique provides potential to improve delayed primary fascial closure rates in the OA setting.

    To assess the feasibility of high-resolution 3D-gradient-recalled echo (GRE) fat-suppressed T1-weighted images using controlled aliasing acceleration technique (CAIPIRINHA-VIBE), and compare image quality and lesion detection to standard-resolution 3D-GRE images using conventional acceleration technique (GRAPPA-VIBE). Eighty-four patients (41 males, 43 females; age range: 14-90 years, 58.8 ± 15.6 years) underwent abdominal MRI at 1.5 T with CAIPIRINHA-VIBE [spatial resolution, 0.76 ± 0.04 mm] and GRAPPA-VIBE [spatial resolution, 1.17 ± 0.14 mm]. Two readers independently reviewed image quality, presence of artefacts, lesion conspicuity, and lesion detection. Kappa statistic was used to assess interobserver agreement. Wilcoxon signed-rank test was used for image qualitative pairwise comparisons. Logistic regression with post-hoc testing was used to evaluate statistical significance of lesions evaluation. Interobserver agreement ranged between 0.45-0.93. Pre-contrast CAIPIRINHA-VIBE showed significantly (p acceleration technique is feasible and yields sharper images compared to standard-resolution images using standard acceleration, with higher post-contrast image quality and trend for improved hepatic lesions detection. • High-resolution imaging of the upper abdomen is clinically feasible using 2D-controlled aliasing acceleration technique. • High-resolution imaging yields significantly sharper images and increased hepatic lesions conspicuity. • High-resolution imaging yields significantly less respiratory motion and residual aliasing artefacts. • Controlled-aliasing offers substantial acquisition-time reduction in patients with breath-holding difficulties.

    We report a case of an atypical presentation of acute appendicitis in an adult due to an undiagnosed congenital gut malrotation. The obvious benefit of observation with serial examinations followed by the use of computed tomography (CT) is discussed in aiding in the diagnosis for atypical presentations of appendicitis. A 45-year-old man who presented with epigastric pain and vomiting was diagnosed with acute left-sided appendicitis on CT scan. The patient's appendix was located in the left lower quadrant of the abdomen due to undiagnosed congenital gut malrotation, thus resulting in an atypical presentation of a common illness. Observation with serial examinations, followed by CT scanning if indicated, is an invaluable strategy to use in diagnosing atypical presentations of common pathology. Copyright © 2013 Elsevier Inc.

    Full Text Available Percutaneous endoscopic gastrostomy (PEG is a standard procedure for enteral feeding tube placement in the stomach for patients with nonobstructive dysphagia. Major and minor complications have been described in early and delayed phase. We describe a 57-year-old hypertensive male patient who underwent PEG for nonobstructive dysphagia after an acute cerebro-vascular accident that presented as right hemiplegia due to pontine hemorrhage. Patient went on to develop nonobstructive spontaneous acute colon dilation from cecum to rectum 72 h after the procedure. Computed tomography scan of the abdomen was undertaken to rule out mechanical obstruction or colon entrapment. Injection Neostigmine was used on day 10 after PEG as there was a recurrence after initial partial resolution. Thereafter patient had an uneventful recovery.

    The widespread use of computed tomography (CT) has increased the medical radiation exposure and cancer risk. We aimed to evaluate the impact of AIDR 3D in CT abdomen-pelvic examinations based on image quality and radiation dose in low dose (LD) setting compared to standard dose (STD) with filtered back projection (FBP) reconstruction. We retrospectively reviewed the images of 40 patients who underwent CT abdomen-pelvic using a 80 slice CT scanner. Group 1 patients (n=20, mean age 41 ± 17 years) were performed at LD with AIDR 3D reconstruction and Group 2 patients (n=20, mean age 52 ± 21 years) were scanned with STD using FBP reconstruction. Objective image noise was assessed by region of interest (ROI) measurements in the liver and aorta as standard deviation (SD) of the attenuation value (Hounsfield Unit, HU) while subjective image quality was evaluated by two radiologists. Statistical analysis was used to compare the scan length, CT dose index volume (CTDIvol) and image quality of both patient groups. Although both groups have similar mean scan length, the CTDIvol significantly decreased by 38% in LD CT compared to STD CT (psuperior image quality in LD CT abdomen-pelvis.

    Abdominal wall hernia secondary to open abdomen management represents a surgical challenge. The hernia worsens due to lateral muscle retraction. Our objective was to evaluate if Botulinum Toxin Type A (BTA) application in lateral abdominal wall muscles modifies its thickness and length. A clinical trial of male trauma patients with hernia secondary to open abdomen management was performed from January 2009 to July 2011. Thickness and length of lateral abdominal muscles were measured by a basal Computed Tomography and 1 month after BTA application. A dosage of 250 units of BTA was applied at five points at each side between the external and internal oblique muscles under ultrasonographic guidance. Statistical analysis for differences between basal and after BTA application measures was performed by a paired Student's t test (significance: p muscle measure modifications in all the patients. Left muscle thickness: mean reduction of 1 ± 0.55 cm (p muscle thickness: mean reduction of 1.00 ± 0.49 cm (p muscle length: mean increase of 2.44 ± 1.22 cm (p muscle length: mean increase of 2.59 ± 1.38 cm (p follow-up of 49 months were observed. BTA application in lateral abdominal muscles decreases its thickness and increases its length in abdominal wall hernia patients secondary to open abdomen management.

    The aim of this study was to assess pain associated with subcutaneous injection into the abdomen and thigh of different combinations of injection speeds and volumes. The study was a single-centre, one-visit, double-blinded, randomized controlled trial in 82 adults with type 1 or type 2 diabetes receiving daily injections of insulin or glucagon-like peptide-1 (GLP-1) agonists. Participants received 17 subcutaneous injections (12 in abdomen, 5 in thigh) of saline at different injection speeds (150, 300 and 450 µl/s), with different volumes (400, 800, 1200 and 1600 µl), and two needle insertions without any injection. Pain was evaluated on a 100-mm visual analogue scale (VAS) (0 mm no pain, 100 mm worst pain) and on a yes/no scale for pain acceptability. Injection speed had no impact on injection pain (p = 0.833). Injection of larger volumes caused significantly more pain [VAS least square mean differences 1600 vs. 400 µl, 7 · 2 mm (95% confidence interval - CI; 4.6-9.7; p pain occurred in the thigh versus the abdomen [9.0 mm (6.7-11.3; p pain, whereas higher injection volumes caused more pain. The results of this study may be of value for guiding patients to use the appropriate injection site and technique to reduce their injection pain. Furthermore, these findings may have important implications for the development of new injection devices and drug formulations for clinical practice. © 2014 John Wiley & Sons Ltd.

    Acute vascular injuries are the second most common cause of fatalities in patients with multiple traumatic injuries; thus, prompt identification and management is essential for patient survival. Over the past few years, multidetector CT (MDCT) using dual-phase scanning protocol has become the imaging modality of choice in high-energy deceleration traumas. The objective of this article was to review the role of dual-phase MDCT in the identification and management of acute vascular injuries, particularly in the chest and abdomen following multiple traumatic injuries. In addition, this article will provide examples of MDCT features of acute vascular injuries with correlative surgical and interventional findings.

    Full Text Available Background: Use of damage control surgery techniques has reduced mortality in critically injured patients but at the cost of the open abdomen. With the option of delayed definitive management of enteric injuries, the question of intestinal repair/anastomosis or definitive stoma creation has been posed with no clear consensus. The purpose of this study was to determine outcomes on the basis of management of enteric injuries in patients relegated to the postinjury open abdomen.Methods: Patients requiring an open abdomen after trauma from January 1, 2002 to December 31, 2007 were reviewed. Type of bowel repair was categorized as immediate repair, immediate anastomosis, delayed anastomosis, stoma and a combination. Logistic regression was used to determine independent effect of risk factors on leak development.Results: During the 6-year study period, 204 patients suffered enteric injuries and were managed with an open abdomen. The majority was men (77% sustaining blunt trauma (66% with a mean age of 37.1 years±1.2 years and median Injury Severity Score of 27 (interquartile range=20-41. Injury patterns included 81 (40% small bowel, 37 (18% colonic, and 86 (42% combined injuries. Enteric injuries were managed with immediate repair (58, immediate anastomosis (15, delayed anastomosis (96, stoma (10, and a combination (22; three patients died before definitive repair. Sixty-one patients suffered intra-abdominal complications: 35 (17% abscesses, 15 (7% leaks, and 11 (5% enterocutaneous fistulas. The majority of patients with leaks had a delayed anastomosis; one patient had a right colon repair. Leak rate increased as one progresses toward the left colon (small bowel anastomoses, 3% leak rate; right colon, 3%; transverse colon, 20%; left colon, 45%. There were no differences in emergency department physiology, injury severity, transfusions, crystalloids, or demographic characteristics between patients with and without leak.

    Acute pancreatitis is a common disease most frequently caused by gallstone disease or excess alcohol ingestion. Diagnosis is usually based on characteristic symptoms, often in conjunction with elevated serum pancreatic enzymes. Imaging is not always necessary, but may be performed for many reasons, such as to confirm a diagnosis of pancreatitis, rule out other causes of abdominal pain, elucidate the cause of pancreatitis, or to evaluate for complications such as necrosis or pseudocysts. Though the majority of patients will have mild, self-limiting disease, some will develop severe disease associated with organ failure. These patients are at risk to develop complications from ongoing pancreatic inflammation such as pancreatic necrosis, fluid collections, pseudocysts, and pancreatic duct disruption. Validated scoring systems can help predict the severity of pancreatitis, and thus, guide monitoring and intervention.Treatment of acute pancreatitis involves supportive care with fluid replacement, pain control, and controlled initiation of regular food intake. Prophylactic antibiotics are not recommended in acute pancreatitis if there is no evidence of pancreatic infection. In patients who fail to improve, further evaluation is necessary to assess for complications that require intervention such as pseudocysts or pancreatic necrosis. Endoscopy, including ERCP and EUS, and/or cholecystectomy may be indicated in the appropriate clinical setting. Ultimately, the management of the patient with severe acute pancreatitis will require a multidisciplinary approach. (c) 2010 Society of Hospital Medicine.

    2016-10-01

    Cough is the most common illness-related reason for ambulatory care visits in the United States. Acute bronchitis is a clinical diagnosis characterized by cough due to acute inflammation of the trachea and large airways without evidence of pneumonia. Pneumonia should be suspected in patients with tachypnea, tachycardia, dyspnea, or lung findings suggestive of pneumonia, and radiography is warranted. Pertussis should be suspected in patients with cough persisting for more than two weeks that is accompanied by symptoms such as paroxysmal cough, whooping cough, and post-tussive emesis, or recent pertussis exposure. The cough associated with acute bronchitis typically lasts about two to three weeks, and this should be emphasized with patients. Acute bronchitis is usually caused by viruses, and antibiotics are not indicated in patients without chronic lung disease. Antibiotics have been shown to provide only minimal benefit, reducing the cough or illness by about half a day, and have adverse effects, including allergic reactions, nausea and vomiting, and Clostridium difficile infection. Evaluation and treatment of bronchitis include ruling out secondary causes for cough, such as pneumonia; educating patients about the natural course of the disease; and recommending symptomatic treatment and avoidance of unnecessary antibiotic use. Strategies to reduce inappropriate antibiotic use include delayed prescriptions, patient education, and calling the infection a chest cold.

    Acute gastrointestinal bleeding-massive acute bleeding from gastrointestinal section is one of the most frequent forms of acute abdomen. The mortality degree in emergency surgery is about 10%. It's very difficult to identify the place of bleeding and etiology. The important purpose of this research is to present the cases of acute gastrointestinal bleeding from the patients which were monitored and treated at The University Clinical Center of Kosova-Emergency Center in Pristina. These inquests included 137 patients with acute gastrointestinal bleeding who were treated in emergency center of The University Clinical Center in Pristina for the period from January 2005 until December 2006. From 137 patients with acute gastrointestinal bleeding 41% or 29% was female and 96% or 70.1% male. Following the sex we gained a high significant difference of statistics (p < 0.01). The gastrointestinal bleeding was two times more frequent in male than in female. Also in the age-group we had a high significant difference of statistics (p < 0.01) 63.5% of patients were over 55 years old. The mean age of patients with an acute gastrointestinal bleeding was 58.4 years SD 15.8 age. The mean age for female patients was 56.4 age SD 18.5 age. The patients with arterial systolic pressure under 100 mmHg have been classified as patients with hypovolemic shock. They participate with 17.5% in all prevalence of acute gastrointestinal bleeding. From the number of prevalence 2 {1.5%} patients have been diagnosed with peptic ulcer, 1 {0.7%} as gastric perforation and 1 {0.7%} with intestine ischemia. Abdominal Surgery and Intensive Care 2 or 1.5% died, 1 at intensive care unit and 1 at nephrology. As we know the severe condition of the patients with gastrointestinal bleeding and etiology it is very difficult to establish, we need to improve for the better conditions in our emergency center for treatment and initiation base of clinic criteria.

    2011-04-01

    Full Text Available Abstract Acute gallbladder volvulus continues to remain a relatively uncommon process, manifesting itself usually during exploration for an acute surgical abdomen with a presumptive diagnosis of acute cholecystitis. The pathophysiology is that of mechanical organo-axial torsion along the gallbladder's longitudinal axis involving the cystic duct and cystic artery, and with a pre-requisite of local mesenteric redundancy. The demographic tendency is septua- and octo-genarians of the female sex, and its overall incidence is increasing, this being attributed to increasing life expectancy. We discuss two cases of elderly, fragile women presenting to the emergency department complaining of sudden onset right upper quadrant abdominal pain. Their subsequent evaluation suggested acute cholecystitis. Ultimately both were taken to the operating room where the correct diagnosis of gallbladder torsion was made. Pre-operative diagnosis continues to be a major challenge with only 4 cases reported in the literature diagnosed with pre-operative imaging; the remainder were found intra-operatively. Consequently, a delay in diagnosis can have devastating patient outcomes. Herein we propose a necessary high index of suspicion for gallbladder volvulus in the outlined patient demographic with symptoms and signs mimicking acute cholecystitis.

    2009-10-01

    Full Text Available Abstract Background For the establishment of functional neural circuits that support a wide range of animal behaviors, initial circuits formed in early development have to be reorganized. One way to achieve this is local remodeling of the circuitry hardwiring. To genetically investigate the underlying mechanisms of this remodeling, one model system employs a major group of Drosophila multidendritic sensory neurons - the dendritic arborization (da neurons - which exhibit dramatic dendritic pruning and subsequent growth during metamorphosis. The 15 da neurons are identified in each larval abdominal hemisegment and are classified into four categories - classes I to IV - in order of increasing size of their receptive fields and/or arbor complexity at the mature larval stage. Our knowledge regarding the anatomy and developmental basis of adult da neurons is still fragmentary. Results We identified multidendritic neurons in the adult Drosophila abdomen, visualized the dendritic arbors of the individual neurons, and traced the origins of those cells back to the larval stage. There were six da neurons in abdominal hemisegment 3 or 4 (A3/4 of the pharate adult and the adult just after eclosion, five of which were persistent larval da neurons. We quantitatively analyzed dendritic arbors of three of the six adult neurons and examined expression in the pharate adult of key transcription factors that result in the larval class-selective dendritic morphologies. The 'baseline design' of A3/4 in the adult was further modified in a segment-dependent and age-dependent manner. One of our notable findings is that a larval class I neuron, ddaE, completed dendritic remodeling in A2 to A4 and then underwent caspase-dependent cell death within 1 week after eclosion, while homologous neurons in A5 and in more posterior segments degenerated at pupal stages. Another finding is that the dendritic arbor of a class IV neuron, v'ada, was immediately reshaped during post

    Full Text Available A pesar de los grandes avances en la cardiología en el siglo XX y XXI, la insuficiencia cardiaca sigue suponiendo la principal causa de hospitalización en las personas ancianas y presentando un pronóstico ominoso. Además, a pesar de los múltiples estudios sobre nuevas dianas farmacológicas, apenas hemos avanzado en el campo del tratamiento, tal vez porque aún existen lagunas en su fisiopatología. No debemos olvidar que la insuficiencia cardiaca es un compendio de signos y síntomas que engloban múltiples órganos y sistemas.  Mucho se está investigando sobre la relación entre riñón y corazón en forma de síndrome cardiorrenal.  Algo cada vez más en boga es el papel del abdomen en la disfunción orgánica de la insuficiencia cardiaca. En ese sentido, el sistema venoso contiene el 70% del volumen sanguíneo, siendo almacenado en su mayor parte dentro de las vísceras abdominales. Un aumento del tono simpático supone aumento intenso del retorno venoso tan importante como para  aumentar las presiones de llenado y justificar una descompensación cardiaca. La congestión sistémica determina un aumento en la presión intraabdominal que está correlacionada con la disfunción renal en la insuficiencia cardiaca avanzada. La hipoperfusión tisular intestinal supone microtraslocación bacteriana promoviendo el status proinflamatorio típico de este síndrome. La visión holística e integrada de la insuficiencia cardiaca puede suponer un avance tanto en la estratificación del riesgo como en las estrategias terapéuticas. Grandes pasos se están dando en este sentido con estudios sobre la ultrafiltración, paracentesis, diálisis peritoneal, suero hipertónico o fármacos adsorbentes del sodio.

    Full Text Available Introduction. Acute intermittent porphyria emerges as a result of partial defect of porphobilinogen deaminase and is manifested by repeated episodes of somatic, psychiatric and neurological disorders. The disease is conducted via the autosomaldominant gene of variable penetration, so most of the carriers never experience seizures. Timely making of diagnosis, screening of blood relatives of the patient and education of patients on avoidance of provoking factors are the key to adequate treatment. Case Outline. A 23-year-old patient having born the third child was hospitalized due to pains in the abdomen and convulsive seizures nine days after the vaginal delivery. At admittance, she suffered a generalized convulsive seizure of clonic-tonic type. The patient immediately underwent a complete clinical, laboratory, bacteriological and ultrasound examination. Bearing in mind the fact that the patient had several convulsive seizures even after the given neurological therapy, haem-arginate was introduced into therapy during four days. The administration of haem-arginate led to the normalization of blood pressure, pulse and bowel function. The administration of haem-arginate led to the normalization of blood pressure, pulse and bowel function. The patient was treated by a team of doctors, in the intensive care ward, with the use of medicaments, which are allowed in the case of acute porphyria. Sixteen days after the admittance, with clean neurological status and gynaecological and ultra-sound findings, she was released for ambulatory treatment. Conclusion. The presented case exhibits the gravity of making a diagnosis of acute intermittent porphyria in puerperium and the necessity of multi-disciplinary approach in treating this disease. Acute intermittent porphyria should be considered in cases of ambiguous abdominal pain, as well as in patients having abdominal pains followed by neuro-psychiatric disorders.

    A case of acute lead poisoning in an infant without overt clinical manifestations of encephalopathy is reported for the first time in Oman. The case was diagnosed at Rustaq Hospital on the basis of (i) history by the mother of giving the child a traditional remedy for treating constipation (ii) X-ray of abdomen showing radio-opaque speckles and (iii) detection of high blood lead levels (83.3 µg/dL) at the toxicology laboratory of the poison control centre. The source of lead was confirmed by high content of inorganic lead (20.2%) found in the sample of the traditional remedy (bint al dahab). The blood lead levels significantly decreased, after the intravenous calcium edetate (EDTA) therapy was given to the baby. The case highlights that early detection and treatment of acute lead poisoning in children can prevent morbidity and sequelae associated with encephalopathy. It also indicated the need for awareness and prevention programme for parents on this issue.

    Between 62 and 90% of cases of acute generalized exanthematous pustulosis are caused by drugs. Its onset is rapid with generalized pustules, fever, and blood neutrophil count over 7000; pustules resolve spontaneously in less than 15 days. A case associated with piroxicam described. A 36-year-old with initial erythema of the thorax and abdomen, accompanied by burning, without fever, which later spread to his forearms, upper arms, and thighs, with face edema. A week earlier he had taken piroxicam for low back pain; at the time of hospitalization he received antihistamines, and topical and systemic steroids. Full blood count showed leukocytes at 8920, eosinophils at 600, neutrophils at 6600, total serum IgE at 188 UI, C-reactive protein at 2.9 mg/L, and no liver, kidney, or lung involvement. Treatment was initiated with intravenous antihistamines and ranitidine, saline, topical Vaseline plus topical mupirocin, and systemic steroids. On the second day of hospitalization neutrophils increased to 9000 and PCR to 3.3. The score to evaluate acute exanthematous pustulosis in the patient was 8, giving a definitive diagnosis. The differential diagnosis should be established primarily with pustular psoriasis. The prognosis is generally good, as reported.

    Gavrilescu, S; Rădulescu, D

    1991-01-01

    In analysis of a group of 48 patients, the authors describe an entity they call acute cholangio-cholecystitis (or acute cholecystitis of choledochal origin) and define it by 4 obligatory criteria: 1. vesicular lesion of acute cholecystitis type; 2. the obstruction of the main bile duct in the direction of its junction with the cystic duct; 3. free duct communication between the gallbladder and the main bile ducts; 4. fluid content (purulent gallbladder) found identical over the whole biliary territory (the gallbladder the main bile ducts the intrahepatic bile ducts). This entity represents 7.6% of the total of acute cholecystitis and was met in 2.8% of the total of the interventions for the main bile ducts obstruction. The deficient biological background of the patients (60% over 60 years old), and other seriousness factors--vesicular destructive lesions associated with biliary peritonitis (7/48), the existence of the duct obstruction, usually calculous (42/48), but also hydatic (3/48) or tumoural (3/48), the multitude and seriousness of the associated lesions are emphasized. The surgery, performed in over 80% emergent cases, was directed to the decomprimation of the main biliary axis to which the increase of the gangrenous cholecyst, treatment of the duct obstructive factor, repair of the internal biliary fistulas, treatment of the consequent peritonitis were added. The results, very often good (71%), were shadowed by a series of complications (29%) which ended in deaths (14.5%). The paper pleads for the early surgery of the lithiasic biliary disease, before the appearance of the inevitable complications.

    2008-01-01

    Introduction Acute sinusitis is defined pathologically, by transient inflammation of the mucosal lining of the paranasal sinuses lasting less than 4 weeks. Clinically, it is characterised by nasal congestion, rhinorrhoea, facial pain, hyposmia, sneezing, and, if more severe, additional malaise and fever. It affects 1−5% of the adult population each year in Europe. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments in people with clinically diagnosed acute sinusitis, and with radiologically or bacteriologically confirmed acute sinusitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to August 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides, different doses [amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides], long-course regimens), antihistamines, cephalosporins or macrolides, decongestants (xylometazoline, phenylephrine, pseudoephedrine), doxycycline, saline nasal washes, steam inhalation, and topical corticosteroids (intra-nasal).

    Acute bronchitis affects over 40/1000 adults a year in the UK. The causes are usually considered to be infective, but only around half of people have identifiable pathogens. The role of smoking or of environmental tobacco smoke inhalation in predisposing to acute bronchitis is unclear. One third of people may have longer-term symptoms or recurrence. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute bronchitis in people without chronic respiratory disease? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 21 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: analgesics, antibiotics (macrolides, tetracyclines, cephalosporins, penicillins, or trimethoprim-sulfamethoxazole [co-trimoxazole]), antihistamines, antitussives, beta(2) agonists (inhaled or oral), and expectorants/mucolytics.

  17. An investigation of human body model morphing for the assessment of abdomen responses to impact against a population of test subjects.

    2017-05-29

    Human body models have the potential to better describe the human anatomy and variability than dummies. However, data sets available to verify the human response to impact are typically limited in numbers, and they are not size or gender specific. The objective of this study was to investigate the use of model morphing methodologies within that context. In this study, a simple human model scaling methodology was developed to morph two detailed human models (Global Human Body Model Consortium models 50th male, M50, and 5th female, F05) to the dimensions of post mortem human surrogates (PMHS) used in published literature. The methodology was then successfully applied to 52 PMHS tested in 14 impact conditions loading the abdomen. The corresponding 104 simulations were compared to the responses of the PMHS and to the responses of the baseline models without scaling (28 simulations). The responses were analysed using the CORA method and peak values. The results suggest that model scaling leads to an improvement of the predicted force and deflection but has more marginal effects on the predicted abdominal compressions. M50 and F05 models scaled to the same PMHS were also found to have similar external responses, but large differences were found between the two sets of models for the strain energy densities in the liver and the spleen for mid-abdomen impact simulations. These differences, which were attributed to the anatomical differences in the abdomen of the baseline models, highlight the importance of the selection of the impact condition for simulation studies, especially if the organ location is not known in the test. While the methodology could be further improved, it shows the feasibility of using model scaling methodologies to compare human models of different sizes and to evaluate scaling approaches within the context of human model validation.

    The objective of this study was to compare the image quality of a dual-energy nonlinear image blending technique at reduced load of contrast medium with a simulated 120-kVp linear blending technique at a full dose during portal venous phase MDCT of the abdomen. Forty-five patients (25 men, 20 women; mean age, 65.6 ± 9.7 [SD] years; mean body weight, 74.9 ± 12.4 kg) underwent contrast-enhanced single-phase dual-energy CT of the abdomen by a random assignment to one of three different contrast medium (iomeprol 400) dose injection protocols: 1.3, 1.0, or 0.65 mL/kg of body weight. The contrast-to-noise ratio (CNR) and noise at the portal vein, liver, aorta, and kidney were compared among the different datasets using the ANOVA. Three readers qualitatively assessed all datasets in a blinded and independent fashion. Nonlinear blended images at a 25% reduced dose allowed a significant improvement in CNR (p images at a full dose. No statistically significant difference existed in CNR and noise between the nonlinear blended images at a 50% reduced dose and the simulated 120-kVp linear blended images at a full dose. Nonlinear blended images at a 50% reduced dose were considered in all cases to have acceptable image quality. The dual-energy nonlinear image blending technique allows reducing the dose of contrast medium up to 50% during portal venous phase imaging of the abdomen while preserving image quality.

    To evaluate the prevalence and clinical features of Celiac disease among children with severe acute malnutrition (SAM). This prospective observational study was conducted in PBM Children Hospital, Bikaner from July 2012 through December 2013. All consecutively admitted children with SAM were recruited. All subjects were screened for Celiac disease by serological test for IgA-anti tissue Transglutaminase (IgA tTG) antibodies. All seropositive children underwent upper gastrointestinal endoscopy for small bowel biopsy for the confirmation. Clinical features of patients with and without celiac disease were compared. The sero-prevalence (IgA tTg positivity) of Celiac disease was found to be 15.38% while prevalence of biopsy confirmed Celiac disease was 14.42% among SAM children. Abdominal distension, diarrhea, anorexia, constipation, pain in abdomen, vitamin deficiencies, edema, clubbing and mouth ulcers were more common in patients of Celiac disease compared to patients without Celiac disease but the difference was statistically significant only for abdominal distension and pain abdomen. There is a high prevalence of Celiac disease in SAM. Screening for Celiac disease (especially in presence of pain abdomen and abdominal distension) should be an essential part of work-up in all children with SAM.

  20. Evaluation of Absorbed Dose of Critical Organ in Rando Phantom under Head, Abdomen and Pelvis Spiral CT Scan by Thermo Luminescent Dosimetery - TLD

    Full Text Available Background & Objectives: Computed tomography (CT represents 11% of all diagnostic radiology procedures but it contributes to almost 67% of the total effective dose to the human population. In head and neck CT which consist of 1/3 of total CT scans, other critical organs such as lenses and thyroid are in the radiation field. Also in the abdomen and pelvis scan, irradiation of ovaries is unavoidable. Because of high sensitivity of these organs, the probability of abnormality and cancer in these organs has increased. Therefore the dose assessment in these organs is very important. The aim of this study is to estimate the absorbed dose in critical organ of patient undergoing common head, neck, abdomen and pelvic spiral CT scan. Materials & Methods: In this study, Lithium fluoride thermo luminescent dosimeters (TLD-100, Harshaw were used to determine the absorbed dose of critical organ of tissue equivalent rando phantom (Alderson research industries, Inc, Stanford, Conn, U.S.A. The phantom was sectional in design and manufactured with a 2.5 cm slab thickness. Each section contained some holes that allowed accommodation of TLDs. At least two crystals were placed in each hole. The average value of the TLD readings was taken as the organ dose. Readouts were obtained on a Harshaw 4500 reader (Harshaw, Ohio, USA. For calibration, the annealed dosimeters were exposed to an X-ray beam resulting from 120 kVp tube voltage and calibration curve was plotted. Results: result of this study showed during head CT scan the maximum absorbed dose belongs to occipital bones skin. Which were about 11.45 mGy and the minimum absorbed dose belong to thyroid gland which was 0.5 mGy. During abdomen & pelvic spiral CT, the maximum absorbed dose of abdomen skin was 23.32 mGy and the minimum absorbed dose in the eye region was 0.15 mGy. The readout results are correlated with the results of spiral CT detector with the “ALARA” principle, we recommend suitable techniques

    The abnormal abdomen (aa) syndrome in Drosophila mercatorum depends on the presence of R1 inserts in a third or more of the X-linked 28S rDNA genes and the absence of selective underreplication of inserted repeats in polytene tissues that is controlled by an X-linked locus (ur) half a map unit from the rDNA complex. This syndrome affects both life history and morphology in the laboratory. Because abnormal morphologies are rarely encountered in nature, the purpose of this study is to see if th...

    An 82-year-old woman was admitted to our hospital with a provisional diagnosis of acute cholecystitis. Abdominal ultrasonography and colour Doppler imaging played the most important role in confirming a diagnosis of gallbladder torsion preoperatively, and we decided to treat it laparoscopically. Operative findings showed that gallbladder was rotated 360° counterclockwise around the cystic duct and artery. This was a complete torsion of a gross type I wandering gallbladder. The patient had an uneventful postoperative course and was discharged. Laparoscopic cholecystectomy has recently been recommended for treating gallbladder torsion. Because the gallbladder is typically minimally adherent to the liver bed, cholecystectomy can be performed easily with minimal invasion. Gallbladder torsion is a relatively rare cause of an acute abdomen and is difficult to diagnose preoperatively, but we could diagnose complete, acute gallbladder torsion preoperatively with ultrasonography and colour Doppler imaging in this case, allowing for safe and completely curative laparoscopic cholecystectomy.

    Acute pancreatitis in children is an uncommon, little known, poorly defined disease and thus is rarely considered in diagnosis of pediatric abdominal pain. It is rare but is being recognized more frequently, and differs from the disease in the adult both in etiology and therapeutic approach. Fifty children with acute pancreatitis were managed. Their history and postoperative course were analyzed in a retrospective study. The clinical presentation was unremarkable; all patients had abdominal pain, specially in epigastrium, and vomiting was the only other clinical sign exhibited by > 80%. More than 40 biliary diseases were the cause of pancreatitis; trauma was the cause in 30%. Diagnosis could be difficult and unnecessary laparotomy was performed in 16 cases (32.0%) instances of suspected acute abdomen. Morbidity included sepsis, diabetic cetoacidosis, and pancreatic pseudocyst. Biliary disease is a frequent cause of both pediatric and adult pancreatitis. They are differences in clinical course and prognosis. In children, pancreatitis is usually confused with appendicitis.

    An 86 year-old woman with a past medical history significant for abdominal hernia and Alzheimer dementia presented to the Emergency Department with a 24 hour history of acute right upper quadrant pain associated with nausea and non-bilious emesis. Physical exam revealed right sided abdominal tenderness with associated mass. All laboratory values were within normal ranges. Both abdominal ultrasound and computed tomography of the abdomen/pelvis revealed a large distended gallbladder with wall thickening and gallstones. Based on presentation and radiologic findings, the emergency general surgery service was consulted for suspected acute cholecystitis. The patient was then admitted for intravenous antibiotics and scheduled for laparoscopic cholecystectomy the following day. Intra-operative findings revealed volvulus with acute necrosis of the entire gallbladder. The gallbladder had a long pedunculated cystic duct and artery that was detorsed before proceeding with resection. Postoperatively, the patient did well and was discharged a few days later tolerating a regular diet.

    Full Text Available Isolated tubal torsion -a rare cause of acute abdomen in children-is usually difficult to diagnose because of non-specific findings. Surgical salphingectomy is required in delayed diagnosis in most cases. Three sexual inactive adolescents diagnosed in isolated tubal torsion (ITT were discussed for its diagnostic features and surgical management. Laboratory tests and radiological studies including ultrasonography (US, color doppler ultrasound were performed in all patients after evaluation for acute lower abdominal pain in emergency department and they underwent surgical intervention with laparotomy (n:2 and laparoscopy (n:1. One of the patients in this study had salpingectomy. Detorsion of the fallopian tube and cyst excision were performed in the remaining two patients who also had paratubal cysts. There was no recurrence in these patients during the follow-up for 3 and 2 years. The isolated tubal torsion should be kept in mind and early surgical management is essential in order to preserve fallopian tube because of its importance in fertility.

    Full Text Available Appendiceal mucocele is a rare cause of acute abdomen. Mucinous appendiceal neoplasms represent 0.2–0.7% of all appendix specimens. The aim of this study is to report a case of a mucinous appendiceal neoplasm presented as acute appendicitis, discussing the clinical and surgical approach in the emergency setting. A 72-year-old female patient was admitted to the emergency department with a clinical examination indicative of acute abdomen. The patient underwent abdominal computed tomography scan which revealed a cystic lesion in the right iliac fossa measuring 8.3 × 5.2 × 4.1 cm, with calcified walls, and a mean density indicative of high protein content. The patient was taken to the operating room and a right hemicolectomy was performed. The postoperative course was unremarkable. The histopathological examination revealed a low-grade mucinous appendiceal neoplasm with negative regional lymph nodes. Ultrasound and CT are useful in diagnosing appendiceal mucocele and synchronous cancers in the emergency setting. The initial operation should include appendectomy and resection of the appendicular mesenteric fat along with any fluid collection for cytologic examination. During urgent appendectomy it is important to consider every mucocele as malignant in order to avoid iatrogenic perforation causing pseudomyxoma peritonei. Although laparotomy is recommended, the laparoscopic approach is not contraindicated.

    Although great progress has been made in the understanding and treatment of acute leukemia, this disease has not been conquered. For emergency providers (EPs), the presentation of these patients to an emergency department presents a host of challenges. A patient may present with a new diagnosis of leukemia or with complications of the disease process or associated chemotherapy. It is incumbent on EPs to be familiar with the manifestations of leukemia in its various stages and maintain some suspicion for this diagnosis, given the nebulous and insidious manner in which leukemia can present.

    Phlegmonous gastritis (PG) is a nonspecific suppurative inflammation disease arising from the submucosal layer, and extending to the full thickness of the stomach. We herein report on a case of acute PG which was diagnosed with abdominal ultrasonography. A 64-year-old man presented at a hospital after having recently undergone pacemaker implantation for the treatment of complete atrioventricular block. He was admitted as an emergency due to a fever of 39 degrees C. He showed anorexia, epigastralgia, vomiting of coffee-ground emesis on the second hospital day, and abdominal ultrasonography (AUS) performed on the third hospital day showed the disappearance of the normal laminated structure and hypoechoic thickening of the stomach walls. Upper gastrointestinal endoscopy revealed significant hyperplasia of the stomach walls, an erythrogenic mucosa, and poor extension. On the fourth hospital day, computed tomography revealed concentric thickening of the stomach walls. Streptococcus pyogenes was cultured from his blood sample. Based on those findings, the patient was diagnosed as having acute phlegmonous gastritis. His clinical symptoms improved and the abnormal ultrasonographic examination findings thereafter returned to normal following the administration of antibiotics. PG should therefore be included in the differential diagnosis when encountering patients with acute abdomen. We experienced a rare case of acute phlegmonous gastritis and AUS was useful for making an early diagnosis.

    Full Text Available The most common casues of acute abdomen during pregnancy are acute appendicitis followed by acute cholecystitis. The case presented is a 33-year-old patient in 16 weeks′ in vitro fertilization and embryo transfer pregnacy who developed acute cholecystitis. Previously there were two unsuccessful cycles, one complicated with ovarian hyperstimulation syndrome. Due to clinical deterioration during intravenous antibiotic therapy laparoscopic cheolecystecomy was performed and acute cholecystitis found. The postoperative course was uneventful. During the first 24 h tocolysis with intravenous fenoterol in addition to peroral atenolol 2 Χ 50 mg was administered. Postoperative course was uneventuful with further normal pregnancy. Elective cesarean section was made in term pregnancy (39 weeks with singleton with Apgar 10/10. Current guidelines do not recommend prophylactic tocolysis in pregnant population with acute abdomen but there is no mention of the IVF-ET subpopulation of patients. Also, there are no guidelines for thromboprophylaxis in such patients with increased risk of thromboembolic accidents. To our knowledge this is the first case report of a laparoscopic cholecystectomy during IVF-ET gestation.

This manuscript reviews key aspects which support understanding the development of pediatric chronic pain, points to the current pediatric chronic pain terminology, addresses effective treatment strategies, and discusses the evidence-based use of pharmacology. Common symptoms of an underlying pain vulnerability present in the three most common chronic pain disorders in pediatrics: primary headaches, centrally mediated abdominal pain syndromes, and/or chronic/recurrent musculoskeletal and joint pain. A significant number of children with repeated acute nociceptive pain episodes develop chronic pain in addition to or as a result of their underlying medical condition “chronic-on-acute pain.” We provide description of the structure and process of our interdisciplinary, rehabilitative pain clinic in Minneapolis, Minnesota, USA with accompanying data in the treatment of chronic pain symptoms that persist beyond the expected time of healing. An interdisciplinary approach combining (1 rehabilitation; (2 integrative medicine/active mind-body techniques; (3 psychology; and (4 normalizing daily school attendance, sports, social life and sleep will be presented. As a result of restored function, pain improves and commonly resolves. Opioids are not indicated for primary pain disorders, and other medications, with few exceptions, are usually not first-line therapy.

    To establish an artificial bladder reflex arc in dogs via an abdominal reflex pathway above the level of spinal cord injury to reinnervate the neurogenic bladder and restore controllable micturition. Ten beagles were used in the experiment. We anastomosed the proximal end of the right T12 ventral root and distal end of the right S2 ventral root by performing autogenous nerve grafting to build an abdomen-to-bladder reflex, whereas the right T12 dorsal root was kept intact. The early function of the reflex arc was evaluated by performing electrophysiological studies as well as by the measurement of intravesicular pressure and histological examination. Single focal stimulation of the right T12 intercostal nerves elicited evoked action potentials at the right vesicular plexus before and after horizontal spinal cord transaction between the L4 and S3 levels. Bladder contraction was successfully initiated by trains of stimuli targeting the right T12 intercostal nerves. The bladder pressures and amplitude of the complex action potentials at the bladder smooth muscles were unchanged after paraplegia was induced; they were comparable to those of the control. Prominent axonal sprouting was observed in the distal part of the nerve graft. Our data showed the effectiveness of bladder innervation above the level of spinal cord injury in inducing micturition by abdomen-to-bladder reflex contractions and, therefore, might provide a new clinical approach for restoring bladder function in individuals with paraplegia.

    The aim of this study was to evaluate the efficacy of vacuum-assisted closure therapy in patients with open abdomen due to secondary peritonitis and to identify possible risk factors of fistula formation. The hospital OPS-database (time period 2005-2014) was searched to identify patients treated with an open abdomen due to secondary peritonitis, who underwent vacuum-assisted closure therapy. Medical records were retrospectively analyzed for patients' characteristics, cause of peritonitis, duration of vacuum therapy, number of relaparotomies, fascial closure rates, and risk factors of fistula formation. Forty-three patients (19 male, 24 female) with a median age of 65 years (range 24-90 years) were identified. The major cause of secondary peritonitis was anastomotic leakage after intestinal anastomosis or bowel perforation, the median APACHE II score was 11. Median duration of VAC treatment was 12 days (range 3-88 days). Twenty of 43 (47 %) patients died from septic complications. Delayed fascial closure was obtained by suturing in 20 of 43 patients (47 %). Overall 16 of 43 (37 %) patients developed enteroatmospheric fistulas. Re-explorations after starting VAC treatment and duration of VAC therapy were significantly associated with the occurrence of enteroatmospheric fistulas (p peritonitis results in a relatively low fascial closure rate and a high risk of fistula formation.

    Acute diarrhea is the second leading cause of under-five mortality in India. It is defined as the passage of frequent watery stools (>3/24 h). Recent change in consistency of stools is more important than frequency. Acute diarrhea is caused by variety of viral, bacterial and parasitic agents. The common ones are: Rotavirus, E. coli, Shigella, Cholera, and Salmonella. Campylobacter jejuni, Giardia and E. histolytica are also not uncommon. The most important concern in management of acute diarrhea in Emergency room (ER) is fluid and electrolyte imbalances and treatment of underlying infection, wherever applicable. It includes, initial stabilization (identification and treatment of shock), assessment of hydration and rehydration therapy, recognition and treatment of electrolyte imbalance, and use of appropriate antimicrobials wherever indicated. For assessment of hydration clinical signs are generally reliable; however, in severely malnourished children sunken eyes and skin turgor are unreliable. Oral Rehydration Therapy is the cornerstone of management of dehydration. Intravenous fluids are not routinely recommended except in cases of persistent vomiting and/or shock. Majority of cases can be managed in ER and at home. Hospitalization is indicated in infants <3 mo, children with severe dehydration, severe malnutrition, toxic look, persistent vomiting and suspected surgical abdomen. Supplementations with zinc and probiotics have been shown to reduce severity and duration of diarrhea; however evidence does not support the use of antisecretary, antimotility and binding agents. Education of parents about hand hygiene, safe weaning and safe drinking water etc., can help in reducing incidence of this important health problem in the country.

    BACKGROUND: The classification of acute appendicitis (AA) into various grades is not consistent, partly because it is not clear whether the perioperative or the histological findings should be the foundation of the classification. When comparing results from the literature on the frequency...... patients were included. In 116 (89 %) of these cases, appendicitis was confirmed histological. There was low concordance between the perioperative and histological diagnoses, varying from 16 to 76 % depending on grade of AA. Only 44 % of the patients receiving antibiotics postoperatively had a positive...... peritoneal fluid cultivation. CONCLUSION: There was a low concordance in clinical and histopathological diagnoses of the different grades of appendicitis. Perioperative cultivation of the peritoneal fluid as a standard should be further examined. The potential could be a reduced postoperative antibiotic use...

    Full Text Available A two-year-old spayed female mixed-breed dog was presented with a five-day history of hemorrhagic gastroenteritis and fever. On physical examination, the dog was lethargic and clinically dehydrated. The skin of the entire ventral abdomen extending to both flanks was erythematous, swollen and painful on palpation. Histopathological examination of skin biopsies revealed a severe diffuse neutrophilic dermatitis and panniculitis, resembling the subcutaneous form of Sweet’s syndrome in humans. A large part of the skin lesion developed full-thickness necrosis. After intensive care, three surgical wound debridements and wound adaptations, the wound healed by secondary intention within ten weeks. In the absence of infection of the skin or neoplasia, a diagnosis of neutrophilic dermatosis and panniculitis, resembling the subcutaneous form of acute febrile neutrophilic dermatosis, was made.

    Full Text Available BACKGROUND Acute appendicitis remains the most common cause of acute abdomen requiring surgical intervention. Diagnosis of appendicitis is done on clinical grounds. The aetiology and pathogenesis of appendicitis are poorly understood. The cause of pain in the cases with clinical diagnosis of acute appendicitis but intraoperatively normal looking appendix remains controversial. The present study aims at determining the cause of pain in these cases by combining routine histopathology, IHC to investigate the status of the enteric nervous system in normal and inflamed appendices. MATERIALS AND METHODS In the present study, 694 patients who underwent appendicectomy with diagnosis of acute appendicitis were included. In 89 cases, there were no signs of inflammation intraoperatively. These appendix specimens were followed by histopathological examination by H&E staining. 69 out of 89 specimens did not have signs of inflammation in histological examination by H&E staining. Cases which are diagnosed as acute appendicitis but histologically negative in H&E staining are taken as study cases. 49 acute appendicitis cases- histologically positive acute appendicitis (HPAA and 20 appendices from right hemicolectomy specimens were taken as controls. All these specimens were subjected to; 1 Routine Haematoxylin & Eosin staining. 2 Toluidine blue stain for mast cell evaluation. 3 Immunohistochemistry by S-100 stain for evaluating size and number of the ganglia. OBSERVATION The mean mast cell count was more in the histologically negative acute appendicitis group when compared to histologically positive acute appendicitis and control group. The mean size and number of the ganglia were more in the histologically negative acute appendicitis group when compared to histologically positive acute appendicitis and control groups. CONCLUSION Neuronal hypertrophy and mast cells may play a role in the pathogenesis of “appendicitis like pain” in patients with

    Full Text Available Introduction: Acute appendiceal diverticulitis is an unusual cause of acute abdomen, considered clinically indistinguishable from acute appendicitis. Material and methods: In a historic cohort study with 27 cases of appendiceal diverticulitis and 54 cases of acute appendicitis, we compared clinical characteristics, diagnostic tests and pathology findings of the two processes. Results: Mean age at presentation was lower in acute appendicitis (37.24 ± 19.98 vs. 54.81 ± 17.55 years, p < 0.001, with significant differences between men (33.33 ± 15.89 vs. 57 ± 18.02 years, p < 0.001 but not between women (41.76 ± 24.87 vs. 50.44 ± 16.69 years, p = 0.34. In the diverticulitis group, 48.15 % had leukocytosis vs. 81.48 % in the appendicitis group (p = 0.02; there was no difference in leukocyte count (13770.37 ± 4382.55 vs. 14279.63 ± 4268.59, p = 0.61. Patients with appendiceal diverticulitis had a higher incidence of appendiceal mucocele (p = 0.01 and a lower proportion of appendiceal gangrene (p = 0.03. There were no differences in appendiceal perforation or ulceration. Symptom duration before emergency department attendance (71.61 ± 85.25 hours vs. 36.84 ± 33.59 hours; Z = -3.1 p = 0.002, duration of surgery (85 ± 40 minutes vs. 60 ± 21 minutes, Z = -3.2, p = 0.001 and the presence of appendicular plastron was higher in patients with diverticulitis vs. appendicitis (8 vs. 5 patients (p = 0.01, Odds ratio 2.2. Conclusions: Appendiceal diverticulitis presents a series of clinical, epidemiological and pathological differences with respect to acute appendicitis. The former shows a more indolent course with delayed diagnosis.

    The purpose of this study was to evaluate the image quality of T2-weighted (T2w) imaging of the abdomen and pelvis based on the acquisition of rotating rectangular stripes of k-space data after successive radiofrequency excitation (BLADE technique) in comparison to T2w turbo-spin-echo (TSE) sequences with Cartesian k-space sampling. A total number of 107 patients with MR imaging of the abdomen or the pelvis were included in this retrospective interindividual study. All exams were performed in the clinical routine at 1.5T. The T2w images were randomly performed in BLADE technique or as TSE sequences. Two blinded radiologists assessed the images, presented in a random order, concerning the delineation of the abdominal and the musculoskeletal structures, the artifacts of these structures, and the overall image qualities. For the abdomen the mean overall image quality of the T2w-BLADE was rated 3.2 vs. 3.1 for T2w-TSE (p=0.871). The mean musculoskeletal/visceral artifacts of the T2w-BLADE were scored as 2.9/3.0 vs. 3.2/2.6 for the T2w-TSE (p=0.101/p=0.051). The delineation of the musculoskeletal, respectively of the visceral structures was assessed for the T2w-BLADE as 3.0/3.4 vs. 3.2/3.1 for the T2w-TSE (p=0.263; p=0.185). For the pelvis the mean overall image quality of the T2w-BLADE was 3.4 vs. 2.9 for the T2w-TSE (p=0.005). Furthermore the musculoskeletal/visceral artifacts were assessed with a mean of 3.6/3.3 for the T2w-BLADE vs. 3.0/2.8 for the T2w-TSE (p=0.005; p=0.011). The musculoskeletal/visceral delineation of the T2w-BLADE was rated 3.6/3.4 vs. 3.0/2.8 for the T2w-TSE sequence (p<0.001; p=0.008). In imaging of the pelvis the overall quality of T2w sequences with k-space sampling in BLADE technique was rated significantly superior compared with the standard Cartesian sampling. Similar results were assessed for the reduction of the amount of artifacts and blurring. By contrast, no significant benefit could be demonstrated for the T2w-BLADE in the abdomen

    Our aim was to compare histological and biomechanical effects of polypropylene (PP) mesh and porcine-derived, cross-linked urinary bladder matrix (cUBM) graft materials using a rabbit vaginal and abdominal model. Forty rabbits were implanted with PP mesh (n = 20) or cUBM (n = 20) in the vagina and abdomen. Two grafts (PP or cUBM) of the same type were placed into each site, so each rabbit had four grafts. Grafts were harvested 12 weeks later and processed for histologic analysis and biomechanical testing. There were high rates of two types of grafts missing in the vagina. Vaginal PP was associated with erosion reaction (67%), whereas abdominal PP and cUBM showed no sign of erosion. All patches adhered to rectus abdominis or vaginal mucosa and shrank to varying degrees, especially for PP grafts. Compared with vaginal PP, vaginal cUBM induced milder chronic inflammation response, had lower scores (P = 0.000) for inflammation response, and showed higher scores for neovascularization (P = 0.000) and fibroblastic proliferation (P = 0.002). In the abdomen, both histopathological parameters were insignificantly different (P > 0.05) between cUBM and PP. The mechanical properties of UBM did not deteriorate following implantation, whereas the ultimate tensile strength and elastic modulus of vaginal PP increased. PP had higher scores for tensile and break strength than did cUBM (P vagina, and maintains mechanical properties in vivo. It may be a promising material for pelvic floor reconstruction.

    Objective In this study we aimed to assess the image quality and degree of vascular enhancement using low-concentration contrast media (LCCM) (300 mg I ml–1) and high-concentration contrast media (HCCM) (370 mg I ml–1) on 64-slice multidetector row CT (MDCT) abdominal CT angiography (CTA). In addition, we aimed to study the feasibility of using HCCM with a reduced total iodine dose. Methods CTA of the abdomen on a 64-slice MDCT was performed on 15 anaesthetised pigs. Study pigs were divided into three groups of five each based on the iodine concentration and dose received: Group A (LCCM; 300 mg I ml–1), Group B (HCCM; 370 mg I ml–1) and Group C HCCM with 20% less iodine dose. The total iodine injected was kept constant (600 mg kg–1) in Groups A and B. Qualitative and quantitative analyses were performed to study and compare each group for image quality, visibility of the branch order of the superior mesenteric artery (SMA), artefacts, degree of enhancement in the aorta and main stem arteries and uniformity of enhancement in the aorta. Groups were compared using the analysis of variance test. Results The image quality of 64-slice MDCT angiography was excellent with a mean score of 4.63 and confident visualisation of the third to fifth order branches of the SMA in all groups. Group B demonstrated superior vascular enhancement, as compared with Groups A and C (p≤0.05). Uniform aortic enhancement was achieved with the use of LCCM and HCCM with 20% less iodine dose. Conclusion 64-slice MDCT angiography of the abdomen was of excellent quality. HCCM improves contrast enhancement and overall CTA image quality and allows the iodine dose to be reduced. PMID:21081582

    Soft-tissue sarcomas are a diverse group of rare mesenchymal malignancies that can arise at any location in the body and affect all age groups. These sarcomas are most common in the extremities, trunk wall, retroperitoneum, and head and neck. In the adult population, soft-tissue sarcomas arising in the abdomen and pelvis are often large masses at the time of diagnosis because they are usually clinically silent or cause vague or mild symptoms until they invade or compress vital organs. In contrast, soft-tissue sarcomas arising from the abdominal wall come to clinical attention earlier in the course of disease because they cause a palpable mass, abdominal wall deformity, or pain that is more clinically apparent. The imaging features of abdominal and pelvic sarcomas and abdominal wall sarcomas can be nonspecific and overlap with more common pathologic conditions, making diagnosis difficult or, in some cases, delaying diagnosis. Liposarcoma (well-differentiated and dedifferentiated liposarcomas), leiomyosarcoma, and gastrointestinal stromal tumor (GIST) are the most common intra-abdominal primary sarcomas. Any soft-tissue sarcoma can arise in the abdominal wall. Knowledge of the classification and pathologic features of soft-tissue sarcomas, the anatomic locations where they occur, and their cross-sectional imaging features helps the radiologist establish the diagnosis or differential diagnosis so that patients with soft-tissue sarcomas can receive optimal treatment and management. In part 1 of this article, the most common soft-tissue sarcomas (liposarcoma, leiomyosarcoma, and GIST) are reviewed, with a discussion on anatomic locations, classification, clinical considerations, and differential diagnosis. Part 2 will focus on the remainder of the soft-tissue sarcomas occurring in the abdomen and pelvis.

    Open abdomen (OA) treatment in patients with peritonitis is increasing worldwide. Various temporary abdominal closure devices are being used. This study included patients with complicated diffuse secondary peritonitis, OA, and vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM). The aim of this study was to describe mortality and major morbidity in terms of delayed primary fascial closure and enteroatmospheric fistula rates. This was a single-academic-center retrospective study of consecutive patients with diffuse peritonitis, OA, and VAWCM between years 2008 and 2016. Descriptive and univariate analyses were performed. Forty-one patients were identified and analyzed. Median age was 59 years, preoperative septic shock was diagnosed in 54% (n = 22), and 59% (n = 24) had a postoperative peritonitis. Mortality was 29% (n = 12), and 76% (n = 31) of patients were admitted in the intensive care unit. The median duration of OA was 7 days with a median of two dressing changes. Delayed primary fascial closure rate among survivors was 92% (n = 33), and enteroatmospheric fistulas developed in 7% (n = 3). In a subgroup analysis, patients with OA in the primary laparotomy for peritonitis (n = 27) were compared with patients with OA in the subsequent laparotomies (n = 14). There were no significant differences between groups. The VAWCM technique in patients with complicated secondary diffuse peritonitis and OA yields excellent results in terms of delayed primary fascial closure rate and a low number of enteroatmospheric fistulas. It seems to be safe to close the abdomen at the index laparotomy, if possible, even if there is a risk of a need of OA later. Therapeutic/care management study, level IV.

    Full Text Available Abstract Introduction Saw palmetto is a phytotherapeutic agent commercially marketed for the treatment of benign prostatic hyperplasia. Evidence suggests that saw palmetto is a safe product, and mild gastrointestinal adverse effects have been reported with its use. We report a case of acute pancreatitis, possibly secondary to the use of saw palmetto. Case presentation A 61-year-old Caucasian man with a history of benign prostatic hyperplasia and gastroesophageal reflux disease developed epigastric pain associated with nausea 36 hours prior to presentation. He denied drinking alcohol prior to the development of his symptoms. His home medications included saw palmetto, lansoprazole and multivitamins. Laboratory results revealed elevated lipase and amylase levels. An abdominal ultrasound demonstrated a nondilated common bile duct, without choledocholithiasis. Computed tomography of his abdomen showed the pancreatic tail with peripancreatic inflammatory changes, consistent with acute pancreatitis. Our patient's condition improved with intravenous fluids and pain management. On the fourth day of hospitalization his pancreatic enzymes were within normal limits: he was discharged home and advised to avoid taking saw palmetto. Conclusion It is our opinion that a relationship between saw palmetto and the onset of acute pancreatitis is plausible, and prescribers and users of saw palmetto should be alert to the possibility of such adverse reactions.

    L.F.F. Botelho

    2010-06-01

    Full Text Available Acute generalized exanthematous pustulosis (AGEP is a rare cutaneous rash characterized by widespread sterile nonfollicular pustules. Cefepime is a fourth generation cephalosporin, used to treat severe infections. A 67-year-old man was admitted with acute gastroenterocolitis. On the seventh day, the patient developed a nosocomial pneumonia and cefepime was initiated. On the fourth day of cephalosporin treatment, he presented with a maculopapular, pruritic eruption affecting the face, neck, abdomen and limbs. One day later he developed disseminated pustular lesions and his temperature was 37°C. Laboratory analysis evidenced leukocytosis and skin biopsy showed subcorneal pustule, edema in the papillary dermis, perivascular inflammatory infiltrate consisting of neutrophils, leukocytoclasia and red cell extravasation in the epidermis. Cefepime was suspended and within 4 days the non-follicular pustules cleared following a desquamation. AGEP is a disease attributed to a variety of causes, but in 90% of the cases it is due to an adverse drug reaction. Antibiotics are implicated in 80% of these cases, mostly penicillins and macrolides. There are few cases associated with cephalosporins. It is very important to consider AGEP in cases of acute pustular rashes and drugs should be investigated as causative agents.

    Acute mesenteric ischemia is an abdominal catastrophe. This has been described as a complex of diseases rather than a single clinical entity. The incidence in United States is 1 in 1000 hospital admissions. The objective of this descriptive study was to determine the clinical presentations and out come after surgery of patients with acute mesenteric ischemia. It was conducted at Dubai Hospital, Dubai, United Arab Emirates. All patients having per operative or histopathological diagnosis of acute mesenteric ischemia from 2002 to 2006 were included. There were 16 patients in all. Their mean age was 51 years, 12 were male and 4 were female. Abdominal pain was present in 16 patients, vomiting in 12 and anorexia in 9 patients. Abdominal tenderness was present in 16 patients, abdominal distension and rebound tenderness in 12 patients. Five patients had hypertension, 4 had myocardial infarction and 4 had diabetes mellitus as risk factors. X-Ray abdomen was done in 13 patients, Ultrasound in 9 and CT Scan in one patient. Resection of bowel was done in 14 patients. Post operatively 5 patients developed pneumonia, 3 had wound dehiscence, 3 had sepsis, and 3 had Lower GI bleeding. Five patients were expired after surgery in the hospital. Four patients were lost to follow up. We should have a high index of suspicion for mesenteric ischemia in patients with unexplained abdominal pain. Early diagnosis and prompt surgical intervention improves the outcome.

  15. Managing acute abdominal pain in pediatric patients: current perspectives

    Full Text Available Nadia M Hijaz, Craig A Friesen Division of Gastroenterology, Hepatology, and Nutrition, Children’s Mercy Kansas City, Kansas City, MO, USA Abstract: Acute abdominal pain in pediatric patients has been a challenge for providers because of the nonspecific nature of symptoms and difficulty in the assessment and physical examination in children. Although most children with acute abdominal pain have self-limited benign conditions, pain may be a manifestation of an urgent surgical or medical condition where the biggest challenge is making a timely diagnosis so that appropriate treatment can be initiated without any diagnostic delays that increase morbidity. This is weighed against the need to decrease radiation exposure and avoid unnecessary operations. Across all age groups, there are numerous conditions that present with abdominal pain ranging from a very simple viral illness to a life-threatening surgical condition. It is proposed that the history, physical examination, laboratory tests, and imaging studies should initially be directed at differentiating surgical versus nonsurgical conditions both categorized as urgent versus nonurgent. The features of the history including patient’s age, physical examination focused toward serious conditions, and appropriate tests are highlighted in the context of making these differentiations. Initial testing and management is also discussed with an emphasis on making use of surgeon and radiologist consultation and the need for adequate follow-up and reevaluation of the patient.

  16. Acute otitis externa

    OpenAIRE

    Hui, Charles PS

    2013-01-01

    Acute otitis externa, also known as ‘swimmer’s ear’, is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

    Full Text Available Clostridium perfringens bacteremia is associated with adverse outcomes. Known risk factors include chronic kidney disease, malignancy, diabetes mellitus, and gastrointestinal disease. We present a 74-year-old man admitted with confusion, vomiting, and abdominal pain. Exam revealed tachycardia, hypotension, lethargy, distended abdomen, and cold extremities. He required intubation and aggressive resuscitation for septic shock. Laboratory data showed leukocytosis, metabolic acidosis, acute kidney injury, and elevated lipase. CT scan of abdomen revealed acute pancreatitis and small bowel ileus. He was started on vancomycin and piperacillin-tazobactam. Initial blood cultures were positive for C. perfringens on day five. Metronidazole and clindamycin were added to the regimen. Repeat CT (day 7 revealed pancreatic necrosis. The patient developed profound circulatory shock requiring multiple vasopressors, renal failure requiring dialysis, and bacteremia with vancomycin-resistant enterococci. Hemodynamic instability precluded surgical intervention and he succumbed to multiorgan failure. Interestingly, our isolate was beta lactamase producing. We review the epidemiology, risk factors, presentation, and management of C. perfringens bacteremia. This case indicates a need for high clinical suspicion for clostridial sepsis and that extended spectrum beta lactam antibiotic coverage may be inadequate and should be supplemented with use of clindamycin or metronidazole if culture is positive, until sensitivities are known.

  18. Laparoscopic Cholecystectomy for Severe Acute Cholecystitis in a Patient with Situs Inversus Totalis and Posterior Cystic Artery

    Full Text Available Situs inversus totalis is an inherited condition characterized by a mirror-image transposition of thoracic and abdominal organs. It often coexists with other anatomical variations. Transposition of the organs imposes special demands on the diagnostic and surgical skills of the surgeon. We report a case of a 34-year-old female patient presented with left upper quadrant pain, signs of acute abdomen, and unknown situs inversus totalis. Severe acute cholecystitis was diagnosed, and an uneventful laparoscopic cholecystectomy was performed. A posterior cystic artery was identified and ligated. Laparoscopic cholecystectomy is feasible in patients with severe acute calculus cholecystitis and situs inversus totalis; however, the surgeon should be alert of possible anatomic variations.

    To improve the understanding of acute obstructive anuria at upper urinary tract in order to cope properly with corresponding clinical problems. The clinical problems of acute obstructive anuria at upper urinary tract in 55 patients was summarized and analysed. Anuria, lumbago, edema and progressive increase of blood creatinine and ureal nitrogen were the main bases of diagnosis. B-typed ultrasonography and plain film of abdomen (KUB) were the first choice in examinations. The treatment principles lied in prompt removal of obstruction as well as effective prevention and treatment of infection to protect renal function to maximum extent. Forty-three cases (78.2%) recovered normal renal function. Ten cases (18.2%) still had azotemia three months after treatment. Two cases gave up treatment. The reason of tumor for anuria should be paid attention to. The first choice in treatments is ureteral intubation by cystoscope. Diuretic should be used cautiously.

    ABSTRACT Strangulated intestinal obstruction is one of the most common types of acute abdomen and requires urgent surgical treatment. Herein, we report a very rare case of strangulated intestinal obstruction caused by an ileo-ileal knot. An 80-year-old woman was admitted to our hospital with suspicion of strangulation ileus and underwent emergency laparotomy after investigation by exploratory single-port laparoscopy. During surgery, a small bowel gangrene caused by an ileo-ileal knot was found. The gangrenous segment was resected, and primary anastomosis was performed. Post-operative recovery was uneventful except for a minor wound infection. Our extensive search of the literature found only 7 case reports of ileo-ileal knot including ours. An ileo-ileal knot should be considered in the differential diagnosis of acute intestinal obstruction, because this rare phenomenon requires urgent surgical treatment; and some complications should be considered during or after surgery.

    Full Text Available Acute pancreatitis occasionally presents as pancreatic abscess with complications like pleural effusion and ascites. There are several pre-disposing factors, the most common being cholelithiaisis, alcohol abuse, infective causes, trauma, and metabolic causes such as diabetic ketoacidosis, while some cases are idiopathic. Here, we report a rare case of acute necrotizing pancreatitis in a 40-year-old male who presented with pain in the abdomen, ascites and left basal pleural effusion. A computerized tomography (CT scan showed findings suggestive of pancreatic necrosis, with abscess formation and free-fluid surrounding area. The aspirated pus sample was processed for Gram staining and culture, which yielded growth of Prevotella species in an anaerobic culture. Exploratory laparotomy was performed and intra-abdominal collection drained. Necrosectomy of the distal tail and body of the pancreas was performed. The patient was started on antibiotics and along with supportive treatment, responded well.

    Midgut malrotation occurs as a result of failure in normal intestinal rotation and fixation during early pregnancy. Pathological conditions reported in the literature involving midgut malrotation predominantly relate to infants and children. In adults malrotation is often revealed as an incidental finding on computed tomography (CT), or the associated altered anatomy can be the cause of atypical clinical symptoms of relatively common intestinal disorders. An unusual presentation of acute appendicitis, with fever and recurrent pain in left iliac fossa is reported. Underlying intestinal malrotation delayed the correct clinical diagnosis of acute appendicitis. It was not until a CT scan was performed that a malrotation was identified. The predominant appearances of malrotation are the siting of the ascending colon, caecum (and appendix) in the left side of the abdomen and the right-sided placement of the duodenojejunal junction.

  3. Dientamoeba fragilis infection presenting to the emergency department as acute appendicitis.

    2003-07-01

    Dientamoeba fragilis is a non-enteroinvasive, protozoan parasite of the human large intestine with a worldwide prevalence. Considered for years to be a non-pathogenic organism, more recent studies suggest that up to 25% of adult hosts and up to 90% of infested children may manifest clinical disease. D. fragilis infestation has been implicated in chronic gastrointestinal syndromes characterized by protean complaints such as post-prandial abdominal pain, chronic diarrhea, flatulence, fatigue, anorexia, and weight loss. Rarely, D. fragilis infestation is the etiology of acute abdominal pain, mimicking a surgical abdomen. A case report is presented that details a patient with a 1-month history of vague abdominal complaints who presented to the Emergency Department with an apparent episode of acute appendicitis.

  4. Blunt abdominal trauma with handlebar injury: A rare cause of traumatic amputation of the appendix associated with acute appendicitis

    Full Text Available We describe traumatic appendicitis in a 7-year-old boy who presented after sustaining blunt abdominal trauma to his right lower abdomen secondary to bicycle handlebar injury. With diffuse abdominal pain following injury, he was admitted for observation. Computed axial tomography (CT obtained at an outside hospital demonstrated moderate stranding of the abdomen in the right lower quadrant. The CT was non-contrasted and therefore significant appendiceal distention could not be confirmed. However, there was a calcified structure in the right pelvis with trace amount of free fluid. Patient was observed with conservative management and over the course of 15 h his abdominal pain continued to intensify. With his worsening symptoms, we elected to take him for diagnostic laparoscopy. In the operating room we found an inflamed traumatically amputated appendix with the mesoappendix intact. We therefore proceeded with laparoscopic appendectomy. Pathology demonstrated acute appendicitis with fecalith. It was unclear as to whether the patient's appendicitis and perforation were secondary to fecalith obstruction, his blunt abdominal trauma or if they concurrently caused his appendicitis. Acute appendicitis is a common acute surgical condition in the pediatric population and continues to be a rare and unique cause of operative intervention in the trauma population.

    Full Text Available Introduction: Primary omental infarction (POI has a low incidence worldwide, with most cases occurring in adults. This condition is rarely considered in the differential diagnosis of acute abdominal pain in childhood. Material and methods: We present 2 cases of omental infarction in an obese 8-year-old boy and a 5-year-old boy who presented with acute abdominal pain in the right abdomen. Both patients were initially treated with intravenous fluids and analgesics with no improvement. Abdominal ultrasound of the first patient showed free intraperitoneal fluid, meteorism and distended bowel loops. The appendix was not visualized. With a presumptive clinical diagnosis of appendicitis the child underwent laparotomy.On entering the peritoneal cavity an omental infarction was seen and a portion of the omentum was resected. Appendectomy was performed.The second patient presented with acute abdominal pain in the right upper quadrant, which started 2 days before. There was a history of possible abdominal trauma about 3 weeks earlier. The patient had repeated ultrasound examinations and a CT scan of the abdomen which showed a omental infarction. He underwent laparoscopy and resection of the omental infarction, as well as incidental appendectomy. Results: The postoperative period was uneventful. The first patient was discharged on day 3, the second patient on day 4 after surgery. Histology showed a normal vermiform appendix and an omental infarction in both cases. Conclusion and discussion: Since the omental infarction as etiology of acute abdominal pain is uncommon in children, we emphasize the importance of accurate diagnosis and appropriate treatment of omental infarction.

    Postoperative hemorrhage is a significant cause of morbidity and mortality following liver resection. It typically presents early within the postoperative period, and conservative management is possible in the majority of cases. We present a case of late post-hepatectomy hemorrhage associated with overt abdominal compartment syndrome resulting from a localized functional compartment within the abdomen. A 68-year-old white man was readmitted with sudden onset of upper abdominal pain, vomiting, and hemodynamic instability 8 days after an uneventful hepatic resection for metachronous colon cancer metastasis. A frozen abdomen with adhesions due to complicated previous abdominal surgeries was encountered at the first intervention, but the surgery itself and initial recovery were otherwise unremarkable. Prompt response to fluid resuscitation at admission was followed by a computed tomography of his abdomen that revealed active arterial hemorrhage in the liver resection site and hemoperitoneum (estimated volume compartment syndrome. Surgical exploration confirmed a small volume of ascites and blood clots (1.2 L) under significant pressure in his supramesocolic region, restricted by his frozen lower abdomen, which we evacuated. Dramatic improvement in his ventilatory pressure was immediate. His abdomen was left open and a negative pressure device was placed for temporary abdominal closure. The fascia was formally closed after 48 hours. He was discharged home at postoperative day 6. Intra-abdominal pressure and radiologic findings of intra-abdominal hemorrhage should be carefully interpreted in patients with extensive intra-abdominal adhesions. A high index of suspicion and detailed understanding of abdominal compartment mechanics are paramount for the timely diagnosis of abdominal compartment syndrome in these patients. Clinicians should be aware that abnormal anatomy (such as adhesions) coupled with localized pathophysiology (such as hemorrhage) can create a so

  8. The Appropriateness of the Length of Insulin Needles Based on Determination of Skin and Subcutaneous Fat Thickness in the Abdomen and Upper Arm in Patients with Type 2 Diabetes

    Full Text Available BackgroundLonger needle and complicated insulin injection technique such as injecting at a 45-degree angle and making skinfolds may decrease patient compliance to insulin injection therapy. In this light, shorter insulin needles have been recently developed. However, it is necessary to ascertain that such shorter needles are appropriate for Korean patients with diabetes as well.MethodsFirst, the diverse demographic and diabetic features of 156 Korean adults with diabetes were collected by a questionnaire and a device unit of body fat measurement. The skin and subcutaneous fat thicknesses of each subject were measured by Ultrasound device with a 7- to 12-MHz probe. Data were analyzed using analysis of variance and multiple linear regression.ResultsThe mean skin thickness was 2.29±0.37 mm in the abdomen and 2.00±0.34 mm in the upper arms, and the mean subcutaneous fat thickness was to 10.15±6.54 mm in the abdomen and 5.50±2.68 mm in the upper arms. Our analysis showed that the factors affecting the skin thickness of the abdomen and upper arms were gender and body mass index (BMI, whereas the factors influencing the subcutaneous fat thickness in the abdomen were gender and BMI, and the factors influencing the subcutaneous fat thickness in the upper arms were gender, BMI, and age. Insulin fluids may not appear to be intradermally injected into the abdomen and upper arms at any needle lengths. The risk of intramuscular injection is likely to increase with longer insulin needles and lower BMI.ConclusionIt is recommended to fully inform the patients about the lengths of needles for insulin injections. As for the recommended needle length, the findings of this study indicate that needles as short as 4 mm are sufficient to deliver insulin for Korean patients with diabetes.

  14. Feature-based respiratory motion tracking in native fluoroscopic sequences for dynamic roadmaps during minimally invasive procedures in the thorax and abdomen

    Fluoroscopic image guidance for minimally invasive procedures in the thorax and abdomen suffers from respiratory and cardiac motion, which can cause severe subtraction artifacts and inaccurate image guidance. This work proposes novel techniques for respiratory motion tracking in native fluoroscopic images as well as a model based estimation of vessel deformation. This would allow compensation for respiratory motion during the procedure and therefore simplify the workflow for minimally invasive procedures such as liver embolization. The method first establishes dynamic motion models for both the contrast-enhanced vasculature and curvilinear background features based on a native (non-contrast) and a contrast-enhanced image sequence acquired prior to device manipulation, under free breathing conditions. The model of vascular motion is generated by applying the diffeomorphic demons algorithm to an automatic segmentation of the subtraction sequence. The model of curvilinear background features is based on feature tracking in the native sequence. The two models establish the relationship between the respiratory state, which is inferred from curvilinear background features, and the vascular morphology during that same respiratory state. During subsequent fluoroscopy, curvilinear feature detection is applied to determine the appropriate vessel mask to display. The result is a dynamic motioncompensated vessel mask superimposed on the fluoroscopic image. Quantitative evaluation of the proposed methods was performed using a digital 4D CT-phantom (XCAT), which provides realistic human anatomy including sophisticated respiratory and cardiac motion models. Four groups of datasets were generated, where different parameters (cycle length, maximum diaphragm motion and maximum chest expansion) were modified within each image sequence. Each group contains 4 datasets consisting of the initial native and contrast enhanced sequences as well as a sequence, where the respiratory motion is

    Purpose: To characterize potential advantages of online-adaptive magnetic resonance (MR)-guided stereotactic body radiation therapy (SBRT) to treat oligometastatic disease of the non-liver abdomen and central thorax. Methods and Materials: Ten patients treated with RT for unresectable primary or oligometastatic disease of the non-liver abdomen (n=5) or central thorax (n=5) underwent imaging throughout treatment on a clinical MR image guided RT system. The SBRT plans were created on the basis of tumor/organ at risk (OAR) anatomy at initial computed tomography simulation (P{sub I}), and simulated adaptive plans were created on the basis of observed MR image set tumor/OAR “anatomy of the day” (P{sub A}). Each P{sub A} was planned under workflow constraints to simulate online-adaptive RT. Prescribed dose was 50 Gy/5 fractions, with goal coverage of 95% planning target volume (PTV) by 95% of the prescription, subject to hard OAR constraints. The P{sub I} was applied to each MR dataset and compared with P{sub A} to evaluate changes in dose delivered to tumor/OARs, with dose escalation when possible. Results: Hard OAR constraints were met for all P{sub Is} based on anatomy from initial computed tomography simulation, and all P{sub As} based on anatomy from each daily MR image set. Application of the P{sub I} to anatomy of the day caused OAR constraint violation in 19 of 30 cases. Adaptive planning increased PTV coverage in 21 of 30 cases, including 14 cases in which hard OAR constraints were violated by the nonadaptive plan. For 9 P{sub A} cases, decreased PTV coverage was required to meet hard OAR constraints that would have been violated in a nonadaptive setting. Conclusions: Online-adaptive MRI-guided SBRT may allow PTV dose escalation and/or simultaneous OAR sparing compared with nonadaptive SBRT. A prospective clinical trial is underway at our institution to evaluate clinical outcomes of this technique.

    Small bowel diverticulitis is a rare cause of an acute abdomen. Originating from acquired diverticula of the jejunum, less often of the ileum, or Meckel diverticulum, the symptoms are non-specific, simulating other acute inflammatory disorders, such as appendicitis, cholecystitis or colonic diverticulitis. The diagnosis of small bowel diverticulitis is solely based on radiologic findings, with computed tomography (CT) regarded as the method of choice. In recent years, a number of case reports have described the spectrum of the CT features in acute small bowel diverticulitis and its dependence on the severity of the inflammatory process. Typical findings are an inflamed diverticulum, inflammatory mesenteric infiltration, extraluminal gas collection and mural edema of adjacent small bowel loops with resultant separation of bowel loops. An enterolith is rarely found in an inflamed diverticulum. Complications include abscesses, fistulae, small bowel obstruction and free perforation with peritonitis. Small bowel diverticulitis can be a diagnostic problem if it involves the terminal ileum or Meckel's diverticulum. For preoperative confirmation of the presumed diagnosis of small bowel diverticulitis on CT, an enteroclysis for acquired diverticula or a technetium scan for Meckel's diverticulum should be performed. We present the CT findings in three patients of acute small bowel diverticulitis, two affecting the jejunum and one a Meckel's diverticulum. (orig.) [German] Die akute Duenndarmdivertikulitis ist eine seltene Ursache eines akuten Abdomens.

    To evaluate the diagnostic value of the T1 bright appendix sign for the diagnosis of acute appendicitis in pregnant women. This retrospective study included 125 pregnant women with suspected appendicitis who underwent magnetic resonance (MR) imaging. The T1 bright appendix sign was defined as a high intensity signal filling more than half length of the appendix on T1-weighted imaging. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the T1 bright appendix sign for normal appendix identification were calculated in all patients and in those with borderline-sized appendices (6-7 mm). The T1 bright appendix sign was seen in 51% of patients with normal appendices, but only in 4.5% of patients with acute appendicitis. The overall sensitivity, specificity, PPV, and NPV of the T1 bright appendix sign for normal appendix diagnosis were 44.9%, 95.5%, 97.6%, and 30.0%, respectively. All four patients with borderline sized appendix with appendicitis showed negative T1 bright appendix sign. The T1 bright appendix sign is a specific finding for the diagnosis of a normal appendix in pregnant women with suspected acute appendicitis. • Magnetic resonance imaging is increasingly used in emergency settings. • Acute appendicitis is the most common cause of acute abdomen. • Magnetic resonance imaging is widely used in pregnant population. • T1 bright appendix sign can be a specific sign representing normal appendix.

  1. Antibiotics versus appendectomy in the management of acute appendicitis: a review of the current evidence

    Background Acute appendicitis remains the most common cause of the acute abdomen in young adults, and the mainstay of treatment in most centres is an appendectomy. However, treatment for other intra-abdominal inflammatory processes, such as diverticulitis, consists initially of conservative management with antibiotics. The aim of this study was to determine the role of antibiotics in the management of acute appendicitis and to assess if appendectomy remains the gold standard of care. Methods A literature search using MEDLINE and the Cochrane Library identified studies published between 1999 and 2009, and we reviewed all relevant articles. The articles were critiqued using the Public Health Resource Unit (2006) appraisal tools. Results Our search yielded 41 papers, and we identified a total of 13 papers within the criteria specified. All of these papers, while posing pertinent questions and demonstrating the role of antibiotics as a bridge to surgery, failed to adequately justify their findings that antibiotics could be used as a definitive treatment of acute appendicitis. Conclusion Appendectomy remains the gold standard of treatment for acute appendicitis based on the current evidence. PMID:21651835

    Background The aim of this study was to assess the prevalence and clinical significance of extra-vascular findings in patients undergoing magnetic resonance angiography of the abdomen, pelvis and lower extremities. Materials and methods Three hundred fifty-two patients underwent abdominal, pelvic and lower extremity 1.5 T magnetic resonance angiography. Clinically relevant vascular and extra-vascular findings were identified. Relevant vascular findings were classified as stenosis, occlusion, aneurysm, sclerosis, dissection or vasculitis. Relevant extra-vascular findings were categorized as 'safe' (Group A), intermediate - requiring additional investigation - (Group B) and malignant/endangering - requiring change of therapy (Group C). Results A total of 2152 clinically relevant vascular findings was identified (6.1/patient). The most frequent vascular finding was femoral artery stenosis (10.6%). Four hundred fifty-one extra-vascular findings were observed (1.3/patient) and classified into Group A (78%), Group B (19.5%) and Group C findings (2.4%). The most frequent malignant findings were lung cancer, lymphoma, osteosarcoma, hepatocellular carcinoma and renal cell carcinoma (7/352 patients). Conclusions Extravascular findings are frequently encountered in magnetic resonance angiography performed for vascular indications. Clinically relevant findings are seen in a substantial part of patients and should prompt further diagnostic work-up.

    The aim of our study was to develop a method that allows the vizualiation and evaluation of implanted mesh in patients after incisional hernia repair with MRI. Furthermore, we assessed problems typically related with mesh implantation like adhesions and muscular atrophy. We enrolled 28 patients after incisional hernia repair. In 10 patients mesh implantation was done by laparoscopy (expanded polytetrafluoroethylene=ePTFE mesh) and in 18 by laparotomy (polypropylene mesh). Functional MRI was performed on a 1.5-T system in supine position. Sagittal and axial TrueFISP images of the entire abdomen were acquired with the patient repeatedly straining. Evaluation included: correct position and intact fixation of the mesh, furthermore visceral adhesions, recurrent hernia and atrophy of the rectus muscle. The ePTFE mesh was visible in all cases; the polypropylene mesh was not detectable. In seven of the ten ePTFE meshes the fixation was not intact; two recurrent hernias were detected. Twenty of 28 patients had intraabdominal adhesions. In 5 cases mobility of the abdominal wall was reduced, and 16 patients showed an atropy of the rectus muscle. Functional cine MRI is a suitable method for follow-up studies in patients after hernia repair. ePTFE meshes can be visualized directly, and typical complications like intestinal adhesions and abdominal wall dysmotility can be assessed reliably.

    Computed tomography (CT) findings of the liver, spleen and intestines of five healthy calves during six examinations in the first 105 days of life were compared with corresponding cadaver slices. The liver was located in the right hemiabdomen adjacent to the diaphragm and right abdominal wall. The caudal vena cava was seen dorsomedially and the portal vein further ventrally. The umbilical vein was seen running from the navel to the liver in all calves in the first scan and in four calves in the second scan. The spleen ran dorsoventrally adjacent to the costal part of the left abdominal wall and appeared sickle-shaped on transverse images. Differentiation of small and large intestines was only possible when the former contained fluid content and the latter gaseous content. The small intestine was in the left hemiabdomen dorsal to the abomasum and caudodorsal to the rumen at the first two examinations. Growth of the forestomachs caused displacement of the small intestine to the right and toward the ventral abdomen caudal to the liver and adjacent to the right abdominal wall. The large intestine was located caudodorsally, and the typical features of the spiral colon were apparent in the dorsal plane. The location of the caecum varied from dorsal to the spiral colon to adjacent to the right abdominal wall with the apex always pointing caudally. The rectum was easily identified in the pelvic region. The size, volume and density of the described organs throughout the study are shown in several tables.

    Time to source control plays a determinant prognostic role in patients having severe intra-abdominal infections (IAIs). Open abdomen (OA) management became an effective treatment option for peritonitis. Aim of this study was to analyze the correlation between time to source control and outcome in patients presenting with abdominal sepsis and treated by OA. We retrospectively analyzed 111 patients affected by abdominal sepsis and treated with OA from May 2007 to May 2015. Patients were classified according to time interval from first patient evaluation to source control. The end points were intra-hospital mortality and primary fascial closure rate. The in-hospital mortality rate was 21.6% (24/111), and the primary fascial closure rate was 90.9% (101/111). A time to source control ≥6 h resulted significantly associated with a poor prognosis and a lower fascial closure rate (mortality 27.0 vs 9.0%, p = 0.04; primary fascial closure 86 vs 100%, p = 0.02). We observed a direct increase in mortality (and a reduction in closure rate) for each 6-h delay in surgery to source control. Early source control using OA management significantly improves outcome of patients with severe IAIs. This damage control approach well fits to the treatment of time-related conditions, particularly in case of critically ill patients.

    To report initial experience of upper abdominal perfusion measurement with 320-detector row CT (CTP) for assessment of liver diseases and therapeutic effects. Thirty-eight patients who were suspected of having a liver disease underwent CTP. There were two patients with liver metastases, two with hemangiomas, and four with cirrhosis (disease group). CTP was repeated for four patients with cirrhosis or hepatocellular carcinoma (HCC) after therapy. Hepatic arterial and portal perfusion (HAP and HPP) and arterial perfusion fraction (APF), and arterial perfusion (AP) of pancreas, spleen, stomach, and intra-portal HCC were calculated. For disease-free patients (normal group), the values were compared among liver segments and among pancreatic and gastric parts. The values were compared between groups and before and after therapy. No significant differences were found in the normal group except between APFs for liver segments 3 and 5, and fundus and antrum. Mean HAP and APF for the disease group were significantly higher than for the normal group. APF increased after partial splenic embolization or creation of a transjugular intrahepatic portosystemic shunt. HPP increased and AP of intra-portal HCC decreased after successful radiotherapy. 320-Detector row CT makes it possible to conduct perfusion measurements of the whole upper abdomen. Our preliminary results suggested that estimated perfusion values have the potential to be used for evaluation of hepatic diseases and therapeutic effects. Copyright © 2011 Elsevier Ireland Ltd.

    Full Text Available Thrombotic thrombocytopenic purpura (TTP is a rare blood disorder with an estimated incidence of 4–5 cases per million people per year. It is characterized by small-vessel platelet-rich thrombi that cause thrombocytopenia, microangiopathic hemolytic anemia and organ damage. There are reports in literature that TTP and acute pancreatitis are associated, indicating each can be the cause of the other. However, acute pancreatitis triggering TTP is very rare. A 71 years old female presented with abdominal pain of 3 days, followed by dark urine. She had icteric sclera, petechial rash and mild epigastric tenderness. Lab findings were significant for hemolytic anemia, thrombocytopenia and elevated lipase. CT of abdomen showed evidence of pancreatitis and cholelithiasis. After admission, patient developed symptoms of stroke. Further investigation showed elevated lactate dehydrogenase and normal coagulation studied with peripheral blood smear showed 5–6 schistocytes/high power field. Disintegrin and metalloproteinase with thrombospondin motifs-13 (ADAMTS13 activity showed less than 3% with high ADAMTS13 inhibitor 2.2. Patient required 6–7 weeks of daily plasmapheresis until she showed complete response. Our patient presented with clinical features of pancreatitis prior to having dark urine and petechial rash. Therefore, we strongly believe that our patient had pancreatitis which was followed by TTP. Patient's ADMTS13 activity was 6% after 10 plasma exchanges, signifying refractory TTP and higher risk for morbidity and mortality. There are limited data and consensus on the management of refractory TTP. TTP and acute pancreatitis are associated. However, refractory TTP following acute pancreatitis is rarely mentioned in the literature. We would like to emphasize the importance of having higher clinical suspicion of the association of both disease entities.

    Pancreatitis is a flogistic disease, caused by activation and digestion of pancreas by its enzymes. Diagnosis is based on integrated evaluation of clinical and laboratoristic data and morphological imaging. To evaluate the severity of pancreatitis there is a clinical classification in interstitial--mild pancreatitis and severe--necrotic one. The evaluation of severity is basic, because it is strictly correlated to the prognosis of the patient. CT has revealed the best method for diagnosis, staging and for evaluate the complications and follow-up and in some cases it is useful for therapeutic change.The abdomen X-Ray in orthostatism is performed in every situation suspected for acute abdominal disease, also if aspecific; the ultrasound can be used as first instance method in patient with clinical suspect of acute pancreatitis; the MR has actually a secondary role for the diagnosis, with only except for dubious cases to exclude primitive tumor of pancreas and pancreatic shock, but it represents, instead, first instance method in patients with adverse reaction to contrast medium. The CPRE has, like angiography, a selective indication.

    The aim of this study was to determine whether hyperechoic fatty tissue (HFT) at transabdominal and transvaginal ultrasonography in women with acute pelvic pain has a diagnostic role. We studied 201 women (mean age, 32 years) with acute pelvic and lower abdominal pain; we performed ultrasonography (US) in all them. Of the 201, 94 with gynecological problems were included., They were divided into two groups: with pelvic inflammatory disease (PID: n = 45) and without PID (n = 49). We evaluated the presence and distribution of HFT and its role in differential diagnosis between PID and non-PID groups. We found, using US, HFT in 36/45 (80%) patients with PID by US. Of the 36, single-center HFT was observed in 12/36 (33.3%) patients and multicentric HFT was detected in 24/36 (66.7%). HFT was present adjacent to inflammatory foci, tuboovarian abscesses or inflamed salpinx in 30 women: HFT was present outside the pelvic cavity in 24. Among the latter 24, HFT was present only in the lower abdomen, and not in the pelvic cavity in 6. In the non-PID group, HFT was found in the lower abdomen and pelvic cavity in 7 women. Four of the seven were misdiagnosed with PID. One of seven women with a hemorrhagic corpus luteal cyst rupture with underlying PID and two with ectopic pregnancy with HFT were correctly diagnosed. The presence of HFT may be a reliable US finding for the diagnosis of PID. HFT distinguishes PID from other acute gynecological problems

    The purpose of this study was to determine the effectiveness of four traditional motor games (“the tunnel”, “the chicken battle”, “the drunk” and “the wheelbarrow race” for strengthening the abdominal muscles. Electromyography (EMG was collected from rectus abdominis (RA, external oblique (EO, and internal oblique (IO from twelve healthy volunteers during the performance of the games and the trunk curl-up exercise. The EMG amplitude was averaged and normalized using maximal voluntary isometric contractions. A two-way ANOVA (muscle / task was used to compare the level of contraction activity and the way the abdominal muscles co-activated during the different tasks. For EO and IO, the EMG amplitudes during the games were equal or greater than the EMG amplitudes of the curl up. The wheelbarrow race produced the highest intensity of contraction for all muscles. The curl up principally activated RA and IO. On the other hand, the games activated the oblique muscles with higher intensity than RA. On the basis of these results, the motor games are effective for abdominal conditioning.

    To compare fused gadoxetate-enhanced Ga-68-DOTANOC PET/MRI and Ga-68-DOTANOC PET/DWI (diffusion-weighted imaging) for the assessment of abdominal neuroendocrine tumours (NETs). Eighteen patients with suspected or histologically proven NETs of the abdomen were enrolled in this retrospective study. All patients underwent Ga-68-DOTANOC PET/CT for a primary search, staging, or restaging, and received an additional MRI, including dynamic gadoxetate-enhanced T1-weighted sequences and DWI (b-values 50, 300 and 600). Co-registered gadoxetate-enhanced PET/MRI and PET/DWI were separately analysed for NET lesions by a nuclear medicine physician and a radiologist in consensus. Sensitivity and specificity were calculated on a per-region, per-organ and per-patient basis. Eighty-seven out of 684 anatomical regions, and 23 out of 270 organs, were NET-positive in 14 out of 18 patients. Region-based sensitivities and specificities were 97.7 % and 99.7 % for gadoxetate-enhanced PET/MRI and 98.9 % and 99.7 % for PET/DWI. Organ-based sensitivities and specificities were 91.3 % and 99.6 % for gadoxetate-enhanced PET/MRI and 95.7 % and 99.6 % for PET/DWI. Finally, patient-based sensitivities and specificities were 100 % and 100 % for gadoxetate-enhanced PET/MRI and 100 % and 75 % for PET/DWI. Sensitivities and specificities of the two methods did not differ significantly. Gadoxetate-enhanced Ga-68-DOTANOC PET/MRI and Ga-68-DOTANOC PET/DWI are equally useful for the assessment of abdominal NETs. (orig.)

  17. UNC79 and UNC80, putative auxiliary subunits of the NARROW ABDOMEN ion channel, are indispensable for robust circadian locomotor rhythms in Drosophila.

    Directory of Open Access Journals (Sweden)

    Bridget C Lear

    Full Text Available In the fruit fly Drosophila melanogaster, a network of circadian pacemaker neurons drives daily rhythms in rest and activity. The ion channel NARROW ABDOMEN (NA, orthologous to the mammalian sodium leak channel NALCN, functions downstream of the molecular circadian clock in pacemaker neurons to promote behavioral rhythmicity. To better understand the function and regulation of the NA channel, we have characterized two putative auxiliary channel subunits in Drosophila, unc79 (aka dunc79 and unc80 (aka CG18437. We have generated novel unc79 and unc80 mutations that represent strong or complete loss-of-function alleles. These mutants display severe defects in circadian locomotor rhythmicity that are indistinguishable from na mutant phenotypes. Tissue-specific RNA interference and rescue analyses indicate that UNC79 and UNC80 likely function within pacemaker neurons, with similar anatomical requirements to NA. We observe an interdependent, post-transcriptional regulatory relationship among the three gene products, as loss of na, unc79, or unc80 gene function leads to decreased expression of all three proteins, with minimal effect on transcript levels. Yet despite this relationship, we find that the requirement for unc79 and unc80 in circadian rhythmicity cannot be bypassed by increasing NA protein expression, nor can these putative auxiliary subunits substitute for each other. These data indicate functional requirements for UNC79 and UNC80 beyond promoting channel subunit expression. Immunoprecipitation experiments also confirm that UNC79 and UNC80 form a complex with NA in the Drosophila brain. Taken together, these data suggest that Drosophila NA, UNC79, and UNC80 function together in circadian clock neurons to promote rhythmic behavior.

    The open abdomen has become a standard technique in the management of critically ill patients undergoing surgery for severe intra-abdominal conditions. Negative pressure and mesh-mediated fascial traction are commonly used and achieve low fistula rates and high fascial closure rates. In this study, long-term results of a standardised treatment approach are presented. Fifty-five patients who underwent OA management for different indications at our institution from 2006 to 2013 were enrolled. All patients were treated under a standardised algorithm that uses a combination of vacuum-assisted wound closure and mesh-mediated fascial traction. Structured follow-up assessments were offered to patients and included a medical history, a clinical examination and abdominal ultrasonography. The data obtained were statistically analysed. The fascial closure rate was 74 % in an intention-to-treat analysis and 89 % in a per-protocol analysis. The fistula rate was 1.8 %. Thirty-four patients attended follow-up. The median follow-up was 46 months (range 12-88 months). Incisional hernias developed in 35 %. Patients with hernias needed more operative procedures (10.3 vs 3.4, p = 0.03) than patients without hernia formation. A Patient Observer Scar Assessment Scale (POSAS) of 31.1 was calculated. Patients with symptomatic hernias (NAS of 2-10) had a significantly lower mean POSAS score (p = 0.04). Vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) seem to result in low complication rates and high fascial closure rates. Abdominal wall reconstruction, which is a challenging and complex procedure and causes considerable patient discomfort, can thus be avoided in the majority of cases. Available results are based on studies involving only a small number of cases. Multi-centre studies and registry-based data are therefore needed to validate these findings.

    The aim of this study was to evaluate the usefulness of abdomen-to-thorax ratio (ATR) measured by antenatal ultrasonography for predicting neonatal survival of fetuses with congenital diaphragmatic hernia (CDH). We identified 75 fetuses who were prenatally diagnosed with CDH and delivered in Seoul National University Hospital from 1998 to 2012, retrospectively. Of these, 40 cases who met the following criteria were included: (i) singleton pregnancy; (ii) a case that had available ultrasonographic images; and (iii) a neonate in whom follow-up until discharge from the hospital was available. ATR was measured as follows: each anteroposterior distance (APD) in the abdominal and thoracic cavity was measured in the same midsagittal plane with the fetal neutral position. A thoracic APD was measured from the back to the distal end of the sternum and an abdominal APD from the back to the most protruding abdominal surface. ATR is the ratio of the abdominal APD versus the thoracic APD. Survival rates were 57.5%. There were significant differences in ATR, lung-head ratio (LHR), observed/expected-LHR, quantitative lung index and intrathoracic liver between survivors and non-survivors. Regression analysis demonstrated that only ATR and intrathoracic position of the liver were independent predictors of survival. ATR by multivariate analysis had the most influence on survival rate (P = 0.002). The area under the receiver-operator curve for prediction of survival from ATR was 0.770 (P = 0.004). The diagnostic cut-off value for ATR was 0.96. Because ATR is effective to predict neonatal survival in CDH fetuses and is easy to measure, it can be used as another powerful parameter for managing CDH fetuses. © 2014 The Authors.

The protocol included physical examination, patient interview, chart review, questionnaires on abdominal wall and stoma complaints and the SF-36 questionnaire. Fifty-five (12 women, 43 men; median age 70 years) of 111 included patients were alive. Follow-up rate was 91 %. Cumulative IH incidence during the whole study was 62 %. One-third of the IHs was repaired. At 5-year follow-up 59 % of IHs were clinically detectable. AW symptoms were equivalent in patients with (15/23) and without (11/21) IH (p = 0.541). SF-36 scores were lower than population mean for component scores and all subscales except bodily pain. Patients with major co-morbidity had lower physical component score [31.6 (95 %, CI 25.6-37.4)] compared to those without [48.9 (95 %, CI 46.2-51.4)]. Major co-morbidity was not associated with IH (p = 0.56), AW symptoms (p = 0.54) or stoma (p = 0.10). Patients with IH or other AW symptoms had similar SF-36 results compared to those without, whereas patients with a stoma had >5 point lower mean scores for general health, social function and physical component score compared to those without. VAWCM treatment results in high incidence of IH. However, at five years, there was no detectable difference in abdominal wall complaints and QoL in patients with IH compared to those without. Lower QoL appeared mainly to be associated with the presence of major co-morbidity.

    The abnormal abdomen (aa) syndrome in Drosophila mercatorum depends on the presence of R1 inserts in a third or more of the X-linked 28S rDNA genes and the absence of selective underreplication of inserted repeats in polytene tissues that is controlled by an X-linked locus (ur) half a map unit from the rDNA complex. This syndrome affects both life history and morphology in the laboratory. Because abnormal morphologies are rarely encountered in nature, the purpose of this study is to see if the female life history traits are still affected under more natural genetic backgrounds and environmental conditions. Two outbred stocks were extracted from the natural population living near Kamuela, Hawaii: KaaX that has only X chromosomes with uraa alleles, and K+X that has only ur+ alleles. These two stocks have nonoverlapping distributions of insert proportions, indicating strong disequilibrium between the ur locus and the rDNA complex. The KaaX stock had almost no morphological penetrance of uraa, indicating that genetic background is important. KaaX expressed longer female egg-to-adult developmental times, increased early adult female fecundity, and decreased female adult longevity compared with K+X. By bagging natural rots of the cactus Opuntia megacantha near Kamuela, Hawaii, it was shown that egg-to-adult developmental time is slowed down by 0.92 days in females bearing uraa alleles in nature, with no detectable slowdown in uraa males. The bagged rot data also indicate that females bearing uraa alleles have a strong fecundity advantage in nature under some ecological conditions but not others.

    Full Text Available With the purpose to evaluate diagnostic efficacy of some clinical symptoms of acute appendicitis 75 women in different terms of pregnancy were examined. Informative content of such symptoms as Kocher- Volkovich, Rovsing, Bartomje - Michelson, Sitkovsky, Gabay, Brendo, Michelson, Ivanov was studied. Pain syndrome was fixed in all examined women. Pain localization was various and depended on the pregnancy term. During the I trimester of pregnancy the most often pain was manifestated in epigastrium and right lower quadrant, rarely in other abdomen regions. In the II trimester in majority of cases pain occurred in right lower quadrant. During III trimester pain prevailed in right upper quadrant of abdomen. Analyzing informative component of researching symptoms there was noted significant decrease (р<0,05; р<0,01; р<0,001 of their diagnostic value with growth of pregnancy term. Therefore Kocher – Volkovich and Rovsing symptoms were the most informative in the I trimester of pregnancy. Diagnostic efficacy of Brendo(67,3%, Michelson(55,7%, Ivanov(59,6% symptoms was higher than that of Kocher – Volkovich (36,5%, Rovsing (28,8%, Sitkovsky (51,9%, Bartomje – Michelson (55,7% symptoms, their value was diminishing together with increase of pregnancy terms.

    2011-05-01

    Rhinosinusitis is one of the most common conditions for which patients seek medical care. Subtypes of rhinosinusitis include acute, subacute, recurrent acute, and chronic. Acute rhinosinusitis is further specified as bacterial or viral. Most cases of acute rhinosinusitis are caused by viral infections associated with the common cold. Symptomatic treatment with analgesics, decongestants, and saline nasal irrigation is appropriate in patients who present with nonsevere symptoms (e.g., mild pain, temperature less than 101°F [38.3°C]). Narrow-spectrum antibiotics, such as amoxicillin or trimethoprim/sulfamethoxazole, are recommended in patients with symptoms or signs of acute rhinosinusitis that do not improve after seven days, or that worsen at any time. Limited evidence supports the use of intranasal corticosteroids in patients with acute rhinosinusitis. Radiographic imaging is not recommended in the evaluation of uncomplicated acute rhinosinusitis. Computed tomography of the sinuses should not be used for routine evaluation, although it may be used to define anatomic abnormalities and evaluate patients with suspected complications of acute bacterial rhinosinusitis. Rare complications of acute bacterial rhinosinusitis include orbital, intracranial, and bony involvement. If symptoms persist or progress after maximal medical therapy, and if computed tomography shows evidence of sinus disease, referral to an otolaryngologist is warranted.

    This review shows the diagnostic potential of computed tomography (CT) in the diagnosis and differential diagnosis of acute left-sided colonic diverticulitis. Using a single detector spiral CT, standard examination of the entire abdomen is performed after oral and rectal administration of diluted iodinated contrast medium with collimation of 8 mm, pitch of 1.5, and reconstruction increment of 8 mm before and after intravenous contrast injection. Intravenous administration of spasmolytic agents, various patient positions, and the thin-section technique with 3-5 mm slices are beneficial in difficult cases. The differential diagnosis of acute left-sided colonic diverticulitis includes tumorous, inflammatory, and ischemic diseases of the colon as well as infarctions of epiploic appendages and the omentum majus. The knowledge of the various CT criteria of acute colonic diverticulitis and their differential diagnoses helps to establish a correct diagnosis in a wide majority of cases. At present, CT is the diagnostic procedure of choice for assessing acute diverticulitis. Distinct knowledge of the CT features helps to differentiate the various entities accurately.

    Acute pancreatitis is a common cause of acute abdomen in pregnant women. The purpose of this study was to determine the frequency at our institution and its management and outcomes. A retrospective analysis of a database of cases presented in 7 consecutive years at a tertiary center was performed. Between December 2002 and August 2009, there were 19 cases of acute pancreatitis in pregnant women, 85% with a biliary etiology. The highest frequency was in the third trimester of pregnancy (62.5% cases). In cases of gallstone pancreatitis, 43.6% of pregnant women had had previous episodes before pregnancy. A total of 52.6% of the patients were readmitted for a recurrent episode of pancreatitis during their pregnancy. Overall, 26.3% of the patients received antibiotic treatment and 26.3% parenteral nutrition. Laparoscopic cholecystectomy was performed during the 2nd trimester in two patients (10.5%). There was no significant maternal morbidity. Acute pancreatitis in pregnant women usually has a benign course with proper treatment. In cases of biliary origin, it appears that a surgical approach is suitable during the second trimester of pregnancy. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    To investigate the usefulness of magnetic resonance imaging (MRI) in the evaluation of pregnant women with acute abdominal and pelvic pain after sonographically (US) indeterminate findings. Forty pregnant patients with acute abdominal and/or pelvic pain, in whom ultrasound was indeterminate, were included in this study. Multiplanar MR images of the abdomen and pelvis were obtained and independently reviewed by two radiologists with discrepancies were resolved by consensus. Correlation of prospective clinical MR interpretations with surgical and obstetric records and clinical follow-up showed correct identification of disease entities in all 40/40 patients. The following disease processes were correctly identified using MRI in 21/40 patients: appendicitis (n = 5), ileal volvulus (n = 1), common bile duct lithiasis (n = 2), pubic chondrosarcoma (n = 1), uterine dehiscence (n = 1), placental hematoma (n = 3), iliac venous thrombosis (n = 2), ulcerative colitis (n = 1), acute pancreatitis (n = 1), hydronephrosis (n = 1), ovarian dermoid (n = 1), and ovarian torsion (n = 2). 19 of the 40 patients had normal findings on MR examinations and unremarkable follow-up. Interobserver agreement for lesion detection was excellent (0.95 k). Magnetic resonance imaging (MRI) is an accurate investigation in detecting the cause of acute abdominal and pelvic pain during pregnancy and should be considered after US indeterminate findings.

    The acute abdomen is a frequent entity at the Emergency Department (ED), which usually needs rapid and accurate diagnostic work-up. Diagnostic work-up with imaging can consist of plain X-ray, ultrasonography (US), computed tomography (CT) and even diagnostic laparoscopy. However, no evidence-based guidelines exist in current literature. The actual diagnostic work-up of a patient with acute abdominal pain presenting to the ED varies greatly between hospitals and physicians. The OPTIMA study was designed to provide the evidence base for constructing an optimal diagnostic imaging guideline for patients with acute abdominal pain at the ED. Thousand consecutive patients with abdominal pain > 2 hours and post hoc assignment of the final diagnosis by an expert panel. The focus of the analysis will be on the added value of the imaging modalities over history and clinical examination, relative to the incremental costs. This study aims to provide the evidence base for the development of a diagnostic algorithm that can act as a guideline for ED physicians to evaluate patients with acute abdominal pain.

    Acute disseminated encephalomyelitis is an inflammatory demyelinating disease of the central nervous system that usually occurs following an antecedent infection or vaccination. Children and young adults are predominantly affected, but it has low incidence in children younger than 3 years. The disease manifests with a wide range of neurological abnormalities and a variable combination of fever, headache, meningism, convulsion and cranial nerve palsies, and there are no pathognomonic clinical or laboratory findings. So, establishment of definitive diagnosis is challenging in infants. This challenge may result in delayed diagnosis and consequently delayed treatment of acute disseminated encephalomyelitis, which may cause permanent neurological disability. Herein, we report an infant with acute disseminated encephalomyelitis, who mimicked the symptoms of meningoencephalitis and the correct diagnosis and treatment were delayed till the development of a severe phase of the disease.

    Acute Renal Failure (RF) is a rare but well recognized complication of Dengue Infection (DI). There has been paucity of published data regarding renal involvement in DI. The aim of the present study was to elucidate different clinical presentations, disease outcomes of DI. To study the frequency, severity and predictors of RF in DI. Patients diagnosed either as Dengue Fever (DF) or Dengue Haemorrhagic Fever/Dengue Shock Syndrome (DHF/DSS) respectively were enrolled for this study. The diagnostic criteria for DI were febrile illness associated with one of the following: 1) detection of dengue-specific IgM capture antibody or Non-Structural Protein1 (NS1) antigen; or 2) a four-fold or greater increase of dengue-specific IgG capture antibody by ELISA and haemoagglutination inhibition assay. Patients were diagnosed as having Acute RF, if serum creatinine was >1.2 mg/dl or who showed improvement by 50% in serum creatinine from the initial value. It is an observational study of medical charts, data of age, gender, and medical history of any underlying diseases in association with the severity of DI of each patient recorded. All of the laboratory results were collected. Parameters that influenced the clinical presentations and outcomes for development of classical DF or DHF/DSS in patients with or without RF were analysed and compared. Descriptive and inferential statistical analysis was carried. The Statistical software namely SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0 and R environment ver.2.11.1 were used. Most common symptoms were fever followed by headache and pain in abdomen. Among the patients with RF, all patients had recovery. The patients with DHF/DSS were more susceptible to develop renal failure compared to DF group. There were statistically significant higher frequencies of renal failure, haemoconcentration, thrombocytopenia, low serum cholesterol. Patients in the RF group also had significantly higher percentages of shock, haemoconcentration

    The authors present one case of acute mesenteric ischemia appeared to the patient 70 years old, with HTA and coronary heart disease with heart arrhythmia treated with angiotensin-converting-enzyme inhibitor, anti arrhythmia agents and antithrombin therapy (trombostop). Acute mesenteric ischemia is not an isolated clinical entity, but a complex of diseases, including acute mesenteric arterial embolus and thrombus, mesenteric venous thrombus and nonocclusive mesenteric ischemia. These diseases have common clinical features caused by impaired blood perfusion of the intestine, bacterial translocation and systemic inflammatory response syndrome. Reperfusion injury is another important feature of nonocclusive mesenteric ischemia. We discuss about the nonocclusive mesenteric ischemia is the most lethal form of acute mesenteric ischemia because of the poor understanding of its pathophysiology and its nonspecific symptoms, which often delay its diagnosis. Although acute mesenteric ischemia is still lethal and in-hospital mortality rates have remained high over the last few decades, accumulated knowledge on this condition is expected to improve its prognosis.

    The present article reports the most recent evidence on the latest advances in the definition, diagnosis and treatment of acute pancreatitis. The concept of acute pancreatitis and its complications is changing and the presence of persistent organ failure is essential to classify a patient as having severe disease. In this context, increased intestinal permeability is seen as an early phenomenon with important prognostic repercussions. Endoscopic ultrasonography is confirmed as the investigation of choice in patients with idiopathic acute pancreatitis or suspected acute biliary pancreatitis. Aggressive water and electrolyte replacement in the first few hours after onset is the key to a favorable clinical course. Conservative treatment and the use of endoscopic necrosectomy are replacing surgery as the treatment of choice of infected pancreatic necrosis. Lastly, the present article discusses the latest evidence on the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) acute pancreatitis.
