PURPOSE: To assess the role of intracavitary contrast-enhanced ultrasound (IC-CEUS) as a focused ultrasound (US) examination aimed at supporting a single physician in the management of interventional procedures for abdominal fluid collections/abscesses. METHODS: In 43 patients (27 M/16 F, median age 68 years, range 35–91), a single physician performed catheter drainage (42) or needle aspiration (3) for the following: 14 infected abdominal fluid collections, 11 non-infected abdominal fluid collections, 9 pyogenic liver abscesses, 8 gallbladder empyema, and 3 infected pancreatic fluid collections. IC-CEUS (0.1–0.2 mL of SonoVue in 20 mL of saline) was carried out during catheter/needle placement and during the follow-up for catheters left in place. RESULTS: Immediate IC-CEUS allowed to verify the (1) correct positioning of the needle/catheter inside the target in all cases and (2) communication with adjacent structures so as to choose a proper treatment in 21% of the cases. Follow-up IC-CEUS aided in the management of 40 catheters left in place. Appropriate treatment was implemented in 19.3% of the cases because of the presence of biliary fistulas and gallbladder perforation. IC-CEUS helped the physician with the appropriate timing of catheter removal by providing information on catheter malfunction (due to obstruction/dislodgement) and the size of residual undrained cavities. No side effects were registered following IC-CEUS. CONCLUSION: Even if not strictly performed at bedside, IC-CEUS may represent an example of point-of-care ultrasound since it allows an interventional clinician to assess needle/catheter placement success, make treatment decisions, and choose the optimal timing for catheter removal with low costs and without side effects.

BACKGROUND The association between bacterial infection and clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreatoduodenectomy (PD) has not been fully elucidated. METHODS Microbiological data for intraoperative bile culture (BC) and drain culture on postoperative day 4 (DC) were collected. The study population was classified into the following three groups: P1 (positive BC and DC), P2 (positive BC and negative DC), and N (negative BC). A total of 209 patients (P1: 38, P2: 72, and N: 99) who underwent PD between May 2013 and May 2018 met the inclusion criteria of the study. RESULTS The rate of CR-POPF was significantly higher in the P1 group (34.2%) than in the P2 (12.5%; P = .007) and N groups (14.1%; P = .008). Between P1 and P2 groups, a significant difference was observed in the proportion of Enterococcus faecalis grown in BC (42.1% vs 4.2%; P

Introduction Intraabdominal fluid collections that previously required surgical intervention can now be drained with less invasive techniques. The use of lumen-apposing metal stents (LAMS) to treat pancreatic pseudocysts and perirectal abscesses has been shown to be a safe and effective technique in adults. We aim to evaluate the indications, outcomes, and complications of the use of LAMS in pediatric patients at our institution. Methods A retrospective chart review was performed to study patients up to 18 years of age at the Children's Hospital at Montefiore who underwent drainage of intraabdominal fluid collections with the use of LAMS. The main outcome measures were technical and clinical success and associated adverse events with LAMS placement. Results Seven patients (2 girls) ranging from 9 to 18 years were identified. Four patients had perirectal abscess postperforated appendicitis and 3 patients had pancreatic pseudocysts. All of the patients had complete resolution of the collections, with no recurrence, and our technical and clinical success rate was 100%. Only 1 patient had mild bleeding after placement that spontaneously resolved. Discussion Our study demonstrates the efficacy and safety of the use of LAMS for the drainage of intraabdominal fluid collections in pediatric patients, although the number of patients included is limited.

Background Ovarian hyperstimulation syndrome (OHSS) is a rare, yet severe, iatrogenic complication of ovulation induction therapy during assisted reproductive procedures. Our group previously detected atypical cells in the ascitic fluid of OHSS patients, although no malignancy developed during follow up. Here, the aim was to perform a comparative analysis of the cytokines present in the abdominal fluid of patients affected by OHSS versus patients with advanced ovarian cancer, a benign adnexal mass, or ovarian endometriosis. Methods This prospective, non-randomized study was conducted at the Clinical Center of the University of Pecs Department of Obstetrics and Gynecology/Reproductive Center between October 2016 and March 2018. Abdominal fluid samples were obtained from 76 patients and subjected to Luminex analysis. The samples were collected from patients with OHSS (OHSS; n = 16), advanced ovarian cancer (OC; n = 22), a benign adnexal mass (BAM; n = 21), or ovarian endometriosis (EM; n = 17). Data were subjected to the non-parametric Kruskal-Wallis test and Spearman’s rank correlation coefficient to identify statistical differences between the four study groups. Results Leukocytosis and hemoconcentration were detected in the peripheral blood of OHSS patients. Abdominal fluid analysis further revealed significantly higher levels of interleukin (IL)-6, IL-8, IL-10, and transforming growth factor (TGF)-β in both the OHSS and OC groups compared to the BAM and EM groups. The highest concentration of vascular endothelial growth factor (VEGF) was detected in the OC group, while a significantly lower level was detected in the OHSS group. Moreover, VEGF levels in OC and OHSS groups were significantly elevated compared to the levels in the BAM and EM groups. Conclusions Vasoactive and hematogenic cytokines were present at higher levels in both the OHSS and OC abdominal fluid samples compared to the fluid samples obtained from the peritoneal cavity of the BAM patients. It is possible that these cytokines play an important role in the formation of ascites.

Background: Little data are available for abscess and non-abscess abdominal fluid collections (AFCs) after gastric cancer surgery and their clinical implications. We sought to analyse the natural history of such collections in a population of patients subject to routine postoperative imaging.Methods: From 1996 to 2012, 1381 patients underwent gastric resections and routine postoperative monitoring with abdominal ultrasound. As a unit protocol, examinations were carried out in all patients prior to drain removal, immediately before discharge, and at follow-up visits.Results: AFCs were diagnosed in 134 (9.7%) patients after a median time from surgery of seven days (interquartile range (IQR) 5-11 days). Sixty-four of the 134 AFCs (48%) were asymptomatic and resolved spontaneously after a median follow-up of 26.5 days (IQR 14-91 days). Seventy (52%) AFCs required interventional drainage. A stepwise logistic regression model demonstrated that interventional treatment was much more likely among patients with enteric fistula (odds ratio (OR) 9.542, 95% CI 1.418-46.224, p=.003) and pancreatic fistula (OR 7.157, 95% CI 1.340-39.992, p=.012).Conclusions: About one half of AFCs after gastric surgery were asymptomatic and eventually resolved spontaneously without any intervention. However, the need for interventional drainage was significantly increased by coexisting pancreatic or enteric fistula.

Endoscopic ultrasonography (EUS) is an established technique for the diagnosis and staging of gastrointestinal (GI) tumors. In the last years, the spread of new devices dedicated to tissue sampling has improved the diagnostic accuracy of EUS fine-needle aspiration (EUS-FNA). The development of EUS-guided drainage of the biliopancreatic region and abdominal fluid collections has allowed EUS to evolve into an interventional tool that can replace more invasive procedures. For instance, techniques using EUS for pancreatic cancer treatment and celiac neurolysis have been described. Moreover, confocal laser endomicroscopy was coupled to EUS for the in vivo histological diagnosis of gastrointestinal, biliopancreatic, and lymph node lesions.

Objective To describe the nonsurgical management of a cat with traumatic pneumoperitoneum. Case series summary A 4-year-old cat was presented following vehicular polytrauma. Thoracic radiographs revealed 4 rib fractures, a scapular fracture, and pneumothorax. Abdominal ultrasound revealed a small volume of free abdominal fluid. Computed tomography showed a mild pneumoretroperitoneum and a pneumoperitoneum in the region of the porta hepatis. The cat was managed conservatively with close monitoring. Exploratory laparotomy was not pursued given patient stability and static serial imaging studies revealing no indications for surgical intervention. After 6 days, the pneumoperitoneum was no longer detectable. New or unique information provided To the authors' knowledge, this is the first report of successful nonsurgical management of traumatic pneumoperitoneum in a cat.

We present a case of an iatrogenic rectothecal fistula in a 34-year-old man who underwent repair of a congenital anterior sacral meningocele, intraoperatively complicated by rectal perforation. Postoperatively, the patient developed symptoms of meningitis prompting concern for the cerebrospinal fluid leak. Subsequent workup with computed tomography (CT) and magnetic resonance imaging demonstrated a postoperative pseudomeningocele and fistulization with an abdominal fluid collection. CT myelography confirmed the fistulous connection was between the pseudomeningocele and the rectum. Clinical suspicion of a rectothecal communication should be elevated for patients who undergo anterior sacral meningocele repair and postoperatively develop symptoms concerning for meningitis. We suggest that CT myelography be considered in the evaluation of viscero-thecal fistulas if clinical or other initial radiologic evaluation suggests the possibility of this diagnosis. Keywords: Iatrogenic rectothecal fistula, Meningocele, Sacral agenesis

Post-operative pancreatic fistula (POPF) following pancreatic resection is a life-threatening surgical complication. Cell sheets were prepared and harvested using temperature-responsive culture dishes and transplanted as patches to seal POPF. Two different mesenchymal stem cell (MSC) sheets were compared in terms of the preventative ability for pancreatic leakage in a rat model. Both rat adipose-derived stem cell (rADSC) and bone marrow-derived stem cell (rBMSC) sheets were transplanted. Those rADSC and rBMSC sheets are created without enzymes and thus maintained their cell-cell junctions and adhesion proteins with intact fibronectin on the basal side, as well as characteristics of MSCs. The rats with post-pancreatectomy rADSC- or rBMSC-sheet patches had significantly decreased abdominal fluid leakage compared with the control group, demonstrated by MR image analysis and measurement of the volume of abdominal fluid. Amylase level was significantly lower in the rats with rADSC-sheet and rBMSC-sheet patches compared with the control groups. The rADSC sheet patches had increased adhesive and immune-cytokine profiles (ICAM-1, L-selectin, TIMP-1), and the rBMSC sheets had reduced immune reactions compared to the control. This is first project looking at the feasibility of tissue engineering therapy using MSC-sheets as tissue patches preventing leakage of abdominal fluid caused by POPF.

Eosinophilic gastroenteritis (EGE) is a rare disorder and eosinophilic infiltration of the gastrointestinal tract is characteristic for it. Eosinophilic ascites may seen in lymphoma, eosinophilic gastroenteritis, peritoneal dialysis, and parasitic infections too. Depending on the dominant layer of infiltration EGE is classified into three types namely, mucosal, muscularis and serosal. Rarest type is the serosal type characterized by primary serosal disease, peripheral eosinophilia and eosinophilic ascites. Here we report a case of serosal EGE. We have discussed clinical cornerstones for diagnosis and response to treatment.A male patient age of 16 presented to the clinic with complaints of self-limiting diarrhea which stop within three weeks and abdominal distension. In physical examination tachypnea, orthopnea and marked abdominal distension were seen. Contrast-enhanced abdominal computed tomography showed the presence of ascites and diffuse thickening of small bowel wall, but did not detect a primary malignancy in the abdominal cavity; and no signs of portal hypertension or liver disease. In laboratory tests significant eosinophilia in blood and abdominal fluid were seen. Leukocyte count was 16680 /mm3 in the hemogram and 60% eosinophil was detected in the peripheral smear. In paracentesis fluid analysis; eosinophilia (70% eosinophil) were detected. Steroid treatment to be completed in six weeks in total was applied to the patient who was diagnosed with eosinophilic ascites. Therapy with corticosteroids resulted in resolution of both the gastrointestinal symptoms and the ascites without hesitation. He had not any complaint during four months follow-up; ascites regressed and examination was normal. EGE is a rare disorder and it should be flashed in patients who presented with unexplained ascites. Since diagnosis of EGE is a diagnosis of exclusion and, apart from malignancies, there are many other secondary causes of eosinophilic intestinal infiltration that must be excluded.

Canine lymphoma is a commonly reported neoplasia and, in most dogs, arises from lymph nodes before spreading to other organs. Renal lymphoma rarely occurs, and kidneys usually are a secondary site of origin. Primary renal lymphoma is infrequently described in the veterinary literature. In this study, we present a rare case of primary renal lymphoma in a dog and a review of similar cases. A 3-year-old male dog was admitted due to anorexia, weakness and vomiting. Clinical examination revealed bilaterally enlarged kidneys. Imaging demonstrated the presence of multiple renal masses. Cytology of abdominal fluid and kidneys led to the diagnosis of large cell lymphoma. Histopathology and immunohistochemistry on tissue samples taken from the kidneys confirmed the cytological diagnosis of lymphoma and categorized it as primary bilateral renal large B-cell lymphoma (LBCL).

Background: Post-operative collections are a recognized source of morbidity after abdominal surgery. Percutaneous drainage is currently considered the standard treatment but not all collections are accessible using this method. Since the adoption of EUS, endoscopic transmural drainage has become an attractive option in the management of such complications. The present study aimed to assess the efficacy, safety and modalities of endoscopic transmural drainage in the treatment of post-operative collections. Methods: Data of all patients referred to our dedicated multidisciplinary facility from 2014 to 2017 for endoscopic drainage of symptomatic post-operative collections after failure of percutaneous drainage or when it was deemed impossible, were retrospectively analyzed. Results: Thirty-two patients (17 males and 15 females) with a median age of 53 years old (range 31-74) were included. Collections resulted from pancreatic (n = 10), colorectal (n = 6), bariatric (n = 5), and other type of surgery (n = 11). Collection size was less than 5 cm in diameter in 10 (31%), between 5 and 10 cm in 17 (53%) ,and more than 10 cm in 5 (16%) patients. The median time from surgery to endoscopic drainage was 38 days (range 6-360). Eight (25%) patients underwent endoscopic guided drainage whereas 24 (75%) patients underwent EUS-guided drainage. Technical success was 100% and clinical success was achieved in 30 (93.4%) after a mean follow-up of 13.5 months (1.2-24.8). Overall complication was 12.5% including four patients who bled following trans-gastric drainage treated with conservative therapy. Conclusions: The present series suggests that endoscopic transmural drainage represents an interesting alternative in the treatment of post-operative collection when percutaneous drainage is not possible or fails.

An intraductal tubulopapillary neoplasm (ITPN) is a very rare pancreatic tumor. Here we report an extremely rare case of an ITPN rupturing and causing acute peritonitis. A 50-year-old woman presented with left flank pain and vomiting. A computed tomography (CT) scan revealed gigantic multilocular cysts in the pancreatic tail and massive fluid collection in the abdominal cavity. The serum, urine, and abdominal fluid amylase levels were highly elevated, so she was conservatively treated with intraperitoneal drainage and antibiotics for a diagnosis of ruptured pancreatic cysts. After this patient recovered, a CT scan revealed a 2-cm low-density mass located in the body of the pancreas. This was diagnosed as a pancreatic ductal adenocarcinoma of the pancreatic body with an intraductal papillary mucinous neoplasm, and a distal pancreatectomy was performed. The tumor was composed of cuboidal high-grade dysplastic cells proliferating in a tubulopapillary growth pattern without mucin production. An immunohistochemical examination revealed that the tumor cells were positive for MUC1 and CK7, but negative for MUC5AC. These features led to the final diagnosis of ITPN. In this case, the solid ITPN growth obstructed the lumen of the main pancreatic duct, and the intraductal pressure of the distal side rose gradually. Then, pancreatic cysts formed and burst into the abdominal cavity when the intraductal pressure was at its maximum. However, an ITPN consists of high-grade atypical cells derived from the pancreatic ductal epithelium in principle, so the rupture may be an independent risk factor for peritonitis carcinomatosa in the future.

Our study aims to investigate the frequency and patterns of delayed manifestations of abdominal and pelvic injuries which may not be identified or which fail to manifest on the initial abdominopelvic CT in posttraumatic patients. For our institutional review board (IRB)-approved retrospective study, our hospital trauma registry was queried for patients with blunt multitrauma and Injury Severity Score (ISS) ≥ 16 between January 2010 and August 2016, yielding 3735 patients. A total of 203 patients received a follow-up abdominopelvic CT within six months from the initial scan and those with new findings on follow-up CT were identified. A retrospective blinded review of the initial CT examinations was performed by two experienced radiologists. The retrospective readings and original reports were compared to categorize the new abnormalities detected on follow-up CT scans. The categories included missed injuries, late presentations and sequelae of trauma, and complications of surgery, hospital admission, and invasive procedures. The patients’ notes were reviewed for the clinical indications, time interval for repeat CT examination, and subsequent clinical management. The software used for statistical analysis of the extracted data was Microsoft Excel for Mac (version 15.33). Out of 3735 patients, 203 patients received 232 follow-up abdominopelvic CTs. The average elapsed time between the initial CT and the follow-up CT was 15 ± 27 days. Evaluation for an abdominal fluid collection was the most common clinical indication, accounting for 40% of the total number (n = 243) of indications. Delayed manifestations and complications of trauma were present in 41 patients due to 47 abnormalities, most commonly related to solid organ injury, followed by abdominal collections and hematoma. Twenty-nine CT findings (62%) were only detectable on follow-up CT, while nine injuries (19%) were missed on initial CT. The findings on repeated CT warranted eight surgical and 15 interventional procedures. A small percentage of traumatic injuries may be unidentified or fail to manifest on the initial CT, resulting in delayed manifestations of abdominopelvic trauma, which may lead to subsequent readmission, delayed management, and more severe medical complications.

Splenic cysts are uncommon, with large cysts and complications being rare. We describe a 6-year-old patient who initially presented 1 day after falling onto her abdomen at the playground with worsening abdominal pain and distention. An ultrasound of the abdomen demonstrated free abdominal fluid in all four quadrants. A subsequent contrast-enhanced computed tomography scan of the abdomen and pelvis was performed which showed a large splenic cyst with open communication to the peritoneal cavity. A congenital primary cyst was confirmed on pathology after partial splenectomy was performed. Although the majority of splenic cysts are asymptomatic, rupture can lead to acute peritoneal signs and mimic other significant causes of abdominal pain such as viscous injury or acute appendicitis.

The ventriculoperitoneal shunt (VPS) is a solution to relieving symptoms of excess cerebral-ventricle cerebrospinal fluid (CSF); draining this extra fluid to the peritoneum. Other forms of shunts exist though less used in relation to VPS; whose choice is mainly determined by patient’s clinical presentation and regressive history. Though rare, VPS is not devoid of complications. Furthermore, primary abdominal complications are rarer, though most present as peritonitis, abscess or shunt catheter dissociation, each with varying short and long term consequences. Recently, abdominal fluid collections are drawing increasing interest, particularly in relation to: encysted collections (abdominal pseudocysts-APC) and excess cerebrospinal fluid (CSF) accumulation (called CSF ascites). We present a case of an abdominal APC diagnosed in an outpatient treated at our referral centre, and explore the involved clinical and surgical aspects. This patient was successfully treated and evolved well post-operatively and up-to-date. Despite vast evolution in neurosurgery, VPS continues being the prima choice in treating hydrocephalus, a procedure prone to complications just like any surgery, though rare. Non-draining shunts usually warrant revision which usually means at least a reoperation. Mechanisms leading to APC formation remain unknown, although a previous bout of sub-clinical peritonitis continues being the dominant hypothesis.

The purpose of this report is to describe 2 cases of chylous ascites (CA) in ferrets. In the first patient, CA was likely secondary to an obstruction of lymphatic drainage due to lymphoma; and in the second patient, CA developed as a postoperative complication of adrenal carcinoma with multiple metastases. In both cases, CA was diagnosed based on the concentration of triglycerides and cholesterol in the abdominal fluid. Medical treatment resulted in partial remission of the CA in the first case; however, the patient suffered an acute death approximately 3 weeks following its initial presenation. In the second patient, multiple abdominocenteses were required to relieve abdominal discomfort and dyspnea. Five days after the adrenal surgery the ferret developed chylothorax and septic peritonitis, and due to its deteriorating condition was humanely euthanatized. Although the final outcomes in the 2 ferret cases were disappointing, advanced neoplastic disease, usually associated with a poor prognosis, was considered the underlying cause of CA in both patients. More studies are required in ferrets diagnosed with CA to determine proper nutritional and medical management, diagnostic tests, and surgical options. Unfortunately, there is little information describing CA in ferrets and the veterinary medical literature as a whole.

Made available in DSpace on 2018-12-11T17:09:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-09-01 A 6-year-old Labrador with history of hyperpnea, respiratory distress, ascites and paraparesis, presented Dirofilaria immitis microfilariae in the blood smear, cytology of the abdominal fluid and urine. The positive samples were confirmed by multiplex-PCR (COI gene) and sequencing, and presented 98% homology to D. immitis (GenBank accession nos. KC107805.1, EU159111.1, EU163945.1, DQ358815.1, and AJ537512-1). Based on the presented results and the physiopathology of the heartworm disease, molecular techniques may be helpful and accurate in the diagnosis of the disease in vertebrates, and microfilaruria, even uncommon, should be considered on a renal failure evaluation.

Cholangiocarcinomas are tumors that arise from the ductal epithelium of the intrahepatic or extra-hepatic bile ducts. Patients are usually asymptomatic or may present with weight loss, fatigue, loss of appetite and abdominal pain (intrahepatic cholangiocarcinomas) or jaundice (extra-hepatic cholangiocarcinomas). Subcapsular bile vessel rupture, due to intrahepatic cholangiocarcinoma, is an extremely rare clinical presentation, which is an emergent and potentially life-threatening complication. We report the case of a 79-year-old female patient suffering from an intrahepatic cholangiocarcinoma that completely obliterated the left main hepatic duct. This obstruction in intrahepatic bile flow had resulted in intraperitoneal rupture of subcapsular bile vessels (not infiltrated by the tumor) of the left liver lobe and formation of spontaneous biloma. The patient was admitted for acute abdominal pain. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) revealed the tumor and an upper abdominal fluid collection. Since the patient was hemodynamically stable and afebrile, a CT-guided percutaneous aspiration of the collection was undertaken, showing a biloma. A left hepatectomy was performed two weeks later and today, sixty months since the incident, the patient enjoys good health, with no signs of local recurrence or distant metastases. Intraperitoneal rupture of bile ducts and subsequent spontaneous biloma formation, due to an intrahepatic cholangiocarcinoma which completely obstructed the left main hepatic duct, is a unique situation and this is the first time to be reported. Prompt surgical management can lead to successful treatment of this rare and difficult entity., Highlights • Spontaneous biloma in the presence of an intrahepatic cholangiocarcinoma is an extremely rare situation. • Spontaneous rupture of bile vessels due an intrahepatic cholangiocarcinoma is an urgent and life-threatening complication. • This is the first case treated with a left hepatectomy and also the first one to report such a long disease-free survival. • Spontaneous bilomas should be considered in patients presented with epigastric pain, hepatic tumor and fluid collection.

Highlights • There is anomaly that bile ducts and portal veins of the Spiegel lobe do not run together. • Incidence of bile leakage after hepatic surgery was reported to be 2.6–15.6%. • A number of treatment strategies for excluded bile leakage have been reported. • Surgical treatment for excluded bile leakage is a quick and reliable procedure., Inroduction The treatments of excluded bile duct leakage after hepatectomy are not easy and various strategies have been reported, such as surgery, ethanol or fibrin glue injection, and portal vein embolization. Presentation of case A 72-year-old man with a surgical history of laparoscopic ileocecal resection for diverticular bleeding was diagnosed as having hepatocellular carcinoma. Right hemihepatectomy was performed, and computed tomography examination on postoperative day 9 showed abdominal fluid collection in the right subphrenic space. Percutaneous intra-abdominal fluid drainage was performed and it was diagnosed as bile leakage. After that it was diagnosed as excluded bile leakage from the Spiegel lobe by drip infusion cholangiographic-computed tomography and endoscopic retrograde cholangiography. To improve this clinical condition, we performed the Spiegel lobe excision on postoperative day 48. The postoperative course was uneventful and the patient was discharged. Discussion According to the postoperative examination, it appeared that the bile duct from the Spiegel lobe joined to the right main bile duct or the bile duct of the right posterior section. This bile duct anomaly was not detected preoperatively on imaging examination. It is most likely that the bile duct from the Spiegel lobe was cut when the hepatoduodenal ligament in the hepatic hilum was peeled. To prevent excluded bile leakage, the hepatoduodenal ligament should be carefully peeled and ligated instead of using energy devices. Conclusion We consider that surgical treatment for postoperative excluded bile leakage is both a quick and reliable procedure in patients with acceptable liver function and anatomical subject.

Hip arthroscopy has become the gold standard for the treatment of femoroacetabular impingement syndrome. Intra-abdominal fluid extravasation is the most commonly reported major complication, with variable rates depending on the measurement method. Little is known about the evolution of the fluid extravasation throughout the surgical procedure, and the risk factors for this complication are in need of validation. We recommend performing mitigating actions including keeping the surgical time to a minimum, monitoring core body temperature, performing psoas release (if planned) last, and keeping inflow fluid pressure as low as possible.

Objectives The aims of this study were to compare the core temperature changes between pediatric patients lying on regular operating room linen drapes and a water-repellent sheepskin rug during living donor liver transplantation (LDLT) and to evaluate the effectiveness of using a water-repellent sheepskin rug in preventing profound hypothermia due to fluid overflow from the abdominal cavity during LDLT. Patients and Methods The operative records of pediatric patients who underwent LDLT from June 1994-September 2003 were reviewed retrospectively. The nasopharyngeal temperature (NT) changes during the LDLT procedure between patients lying on regular operating room drapes (GI) and water-repellent sheepskin rug (GII) were compared and analyzed using the Mann-Whitney U test. A P value Results Thirty-two patients were included in GI and 56 in GII. Profound hypothermia was not observed in any recipients lying on a water-repellent sheepskin rug (GII). The NT after induction and the following 4 hours into the LT procedure were significantly higher in GII than GI. Conclusion Pediatric patients lying on water-repellent sheepskin preserved their core temperature better in comparison to patients lying on linen drapes. The use of a water-repellent sheepskin rug seems to be effective in preventing profound hypothermia related to physical contact with abdominal fluid overflow during the LDLT.

A 12-week-old, crossbreed, male entire dog was evaluated for a three-week history of lethargy, nausea, anorexia, haemorrhagic diarrhoea and free abdominal fluid. Abdominal ultrasound revealed multiple cavitated hepatic masses, abdominal lymphadenopathy and marked abdominal effusion. Fine needle aspiration and culture of the hepatic lesions and lymph nodes identified hepatic abscessation and pyogranulomatous lymphadenitis, with a heavy growth of Escherichia coli. Intravenous fluid therapy and antimicrobial therapy were initiated. Persistent hypotension and hypoglycaemia during hospitalisation, despite intensive treatment, were suggestive of systemic inflammatory response syndrome, septic shock and multiple organ dysfunction syndrome. Due to patient morbidity and poor response to treatment, euthanasia was performed.

Trial Design: The aim of this study was to identify independent risk factors for post-pancreatoduodenectomy (post-PD) abdominal fluid collections (AFCs) and evaluate our management protocol on it. Methods: A retrospective analysis of consecutive 2064 cases who underwent PD over the past decade in 1 single center was conducted. The patients were divided into AFCs and non-AFCs group. Univariable and multivariate logistic regression analysis was performed to identify independent risk factors of AFCs. The AFCs group was compared with the non-AFCs group with respect to the incidence of postoperative outcomes. The characteristics of AFCs were further analyzed in terms of clinical manifestations. Results: Two thousand sixty-four cases with pancreaticoduodenectomy were recruited and 15% of them were found AFCs. Diameter of main pancreatic duct ≤3 mm was found to be an independent predictor of AFCs (P 800 mL (P

Background Acute appendicitis in children is the most common condition requiring urgent evaluation and surgery in the emergency department. At times, despite the appendix being seen on ultrasound (US), there can be discrepancy as to whether a patient has clinical appendicitis. Secondary findings suggestive of appendicitis can be helpful in identifying and evaluating these children. Objective The aim of this study was to determine if specific US findings and/or laboratory results are predictive of appendicitis in children with a visualized appendix on US. Methods A prospective study was conducted on children (birth to 18 years) presenting to the pediatric emergency department with suspected appendicitis who underwent right-lower-quadrant US. Ultrasound findings analyzed appendix diameter, compressibility, increased vascularity, presence of appendicolith, inflammatory changes, right-lower-quadrant fluid near the appendix, lower abdominal fluid, tenderness during US, and lymph nodes. Diagnosis was confirmed via surgical pathology. Results There were 1252 patients who enrolled, 60.8 (762) had their appendix visualized, and 39.1 (490) did not. In children where the appendix was seen, 35.2% (268) were diagnosed with appendicitis. Among patients with a visualized appendix, the likelihood of appendicitis was significantly greater if the appendix diameter was 7 mm or greater (odds ratio [OR], 12.4; 95% confidence interval [CI], 4.7-32.7), an appendicolith was present (OR, 3.9; 95% CI, 1.5-10.3), inflammatory changes were seen (OR, 10.2; 95% CI, 3.9-26.1), or the white blood cell (WBC) count was 10,000/μL (OR, 4.8; 95% CI, 2.4-9.7). A duration of abdominal pain of 3 days or more was significantly less likely to be associated with appendicitis (OR, 0.3; 95% CI, 0.08-0.99). The absence of inflammatory changes, WBC count of less than 10,000/μL, and appendix diameter of 7 mm or less had a negative predictive value of 100%. Conclusions When the appendix is seen on US but diagnosis of appendicitis is questioned, the absence of inflammatory changes, WBC count of less than 10,000/μL, and appendix diameter of 7 mm or less should decrease suspicion for appendicitis.

Background : Cholangiocellular carcinoma is a malignant tumor that occurs mainly in elderly dogs and cats. Primary hepatobiliary neoplasms are considered rare in felines, although cholangiocarcinoma is the most common tumor type among malignant liver tumors in the species. The objective of this work is to report two cases of cholangiocarcinoma in young domestic cats, with three years old, and to approach clinical and pathological aspects to promote awareness of this type of injury in young animals, with a focus on prevention of predisposing factors. Cases : A 3-year-old male domestic cat (cat 1) had a history of progressive weight loss, persistent vomiting, diarrhea, and episodes of seizure. At the clinical examination was noted moderate degree of jaundice. In the biochemical exams it was verified as alteration hypoproteinemia, increase of urea and hyponatremia. Abdominal ultrasonography revealed a formation in the left epigastric region measuring 8.0 x 5.0 cm, with a diffusely heterogeneous parenchyma, suggestive of hepatic neoplasia, in addition to the presence of free abdominal fluid. Cavity fluid analysis was suggestive of carcinoma. A 3-year-old male domestic cat (cat 2), with history of hyporexia, emaciation and vomiting was taken to care. Physical examination showed moderate dehydration, hypocorous mucosa and presence of abdominal mass on palpation. The animal's serum biochemical assessment were verified as changes, increasing AST. Ultrasonographic examination showed an abdominal mass, located caudally to the spleen, with irregular shape, measuring approximately 4.7 cm suggestive of hepatic neoplasia, in addition to the presence of abdominal fluid. The hepatic cytology performed by fine needle aspiration was suggestive of carcinoma. After the clinical worsening of two cats and due unfavorable prognosis, euthanasia and necropsy were performed. In the macroscopic analysis of cat 1, numerous nodules of whitish and sometimes "umbilicate" coloration were observed in the liver, measuring up to three cm in diameter, distributed randomly by the hepatic parenchyma and with a soft consistency at cut. An ovoid-wicking mass, measuring 6.0 x 7.0 x 5.0 cm in diameter and coloring ranging from white to light brown was checked together. In the macroscopic evaluation of cat 2, numerous coalescing masses of whitish coloring measuring up to 6.0 cm in diameter were observed covering almost every hepatic parenchyma and also affecting the pancreas, with a soft consistency at cut. The microscopic findings of both cats were compatible with the diagnosis of cholangiocarcinoma. Considering the immunohistochemical profile, in both cases there was positivity for the CK Pan antibody and CEA and negativity for the CK20, TTF-1, Hepatocyte specific antigen, CD10 and CD56 antibodies. Discussion : Cholangiocarcinomas usually occur in elderly animals, with a mean age of 9 years, so it may be suggested that the cause of the disease in cat 1 and 2 was possibly related to the early and continuous presence of carcinogens. The biliary duct trematod Platynosomum fastosum , the chemical agents plutonium and americium, intestinal parasites such as Ancylostoma spp. and Trichuris vulpis , as well as the occurrence of chronic inflammations independent of etiology are commonly involved in the occurrence of cholangiocarcinoma. Clinical and anatomopathological observations made evident that these two young cats, with three years old, had metastatic cholangiocarcinoma. Thus, veterinary providers should be aware that this tumor type can occur in young animals and is mindful of means of prevention and / or recommended treatment of predisposing factors.

A five-month-old Belgian Blue female calf presented with a 72-hour history of depression, anorexia, muscle weakness and severe abdominal distension. Abdominal ultrasonography and abdominocentesis revealed the presence of uroperitoneum due to bladder rupture. Venous blood gas analysis showed haemoconcentration, hyperkalaemia and metabolic acidosis. Electrolytes and fluid balance were corrected with aggressive fluid therapy and peritoneal drainage overnight, and surgery was scheduled for the following day. Intraoperatively, gradual drainage of abdominal fluid was performed to avoid sudden haemodynamic changes, and despite successful bladder reconstruction, near the end of surgery, the patient developed severe bradycardia, atrial standstill, sine waves and pulseless electrical activity, unresponsive to cardiopulmonary resuscitation. Cardiac arrest in this calf was likely caused by a combination of washout of toxic product from previous ischaemic tissues, severe acidosis, severe hypoxaemia and electrolyte disturbances. Clinicians should be prepared to handle possible complications of uroperitoneum.

Rationale: Spontaneous uterine rupture during pregnancy, occurring most often during labor in the context of a scarred uterus, is a serious obstetric complication. Perhaps even more serious because of its extreme rarity, spontaneous uterine rupture in a primigravid patient with an unscarred gravid uterus would be essentially unexpected. Clinical manifestations of unscarred uterine ruptures are nonspecific and can be confusing, making a correct early diagnosis very difficult. Patient concerns: A primigravid woman at 27 weeks of gestation presented to our hospital with acute oligohydramnios. Ultrasound examination at her local hospital revealed oligohydramnios that had not been present 1 week previously. A specific cause of the acute oligohydramnios, however, was not established. Diagnosis: Upon transfer to our hospital, the patient was hemodynamically stable without abdominal tenderness or peritoneal signs. Transabdominal ultrasound was repeated and confirmed oligohydramnios and seroperitoneum. The fetal heart rate was in the normal range, and blood tests revealed a low hemoglobin level of 91 g/L, which had been normal recently. A repeat sonogram after admission found that there was almost no amniotic fluid within the uterine cavity, and there was increased peritoneal fluid. Repeat hemoglobin showed a further decrease to 84 g/L. The combination of increased free abdominal fluid, lack of intrauterine fluid, and acutely decreasing hemoglobin strongly suggested uterine rupture with active intraperitoneal bleeding. Interventions: Emergent laparotomy was performed, and a male infant was delivered. Comprehensive abdominal exploration revealed a rupture in the right uterine cornua with ongoing slow bleeding, through which a portion of the amniotic sac protruded into the abdominal cavity. Outcomes: The laceration was repaired, the patient and neonate recovered without complications, and were discharged 5 days postoperatively. Lessons: An increased awareness of the rare but real possibility of spontaneous uterine rupture in a primigravid patient with no prior uterine scarring helped to establish an earlier diagnosis. Obstetricians should consider this possibility in pregnant females, even in the absence of risk factors and in early gestational age, when sudden unexplained clinical manifestations, such as acute oligohydramnios, are encountered.

Transvaginal aspiration of oocytes (TVA) in the equine industry has gained more relevance and become a valuable technique to produce offspring from subfertile mares. TVA is a semi-invasive procedure and requires handling the ovaries transrectally to position them closely to an ultrasound probe located in the mare’s vagina. Once the ovary lies in close apposition to the ultrasound probe, a 12G needle is inserted through the needle guide, puncturing, aspirating, and scraping each follicle to recover the oocyte. Potential complications described include rectal tears, puncturing of blood vessels, ovarian abscesses, and peritonitis. Occasionally, problems occur after uneventful procedures, such as colic, peritonitis, pain, and anorexia. However, the source of these complications is not fully known. We hypothesize that blood and peritoneal fluid parameters would differ pre- and post-TVA in mares. A few reports provide some parameters after TVA (e.g. peritoneal protein, neutrophils, nucleated cells) without reference to pre-TVA values. These studies have not identified an effect in peritoneal fluid variables due to multiple abdominocenteses. Therefore, our aim was to analyse blood and peritoneal fluid in mares pre- and post-TVA, and to identify changes in parameters of the procedure (duration, number of pokes, number of follicles) and the mares’ clinical responses. Ten healthy mares were selected to undergo the procedure. Thirty minutes before starting TVA, a blood sample was drawn for complete blood count (CBC) and blood chemistry, and abdominocentesis was performed to obtain abdominal fluid and assess the cytology. This same protocol was repeated 24 hours after TVA. Physical exams were performed pre- and post-TVA. Paired t-tests were used to identify differences between groups (pre- and post-TVA). Spearman correlations (ρ) were used to assess the relationship between variables. There was a significant increase in peritoneal lactate (5.65-fold), peritoneal total protein (2.4-fold), and total nucleated cells (46-fold) between pre- and post-samples. These parameters were not associated with operator, number of times the needle was introduced into the ovaries, or number of aspirated follicles. The remaining parameters evaluated in CBC and blood chemistry did not differ. A positive correlation between total peritoneal protein and blood albumin was found post-TVA (ρ=0.72, P=0.01) but not pre-TVA (ρ=−0.1, P=0.65), suggesting an increase in protein level due to bleeding. Clinically, 9 mares were healthy throughout the study except one that presented signs of pain (facial grimace, anorexia, hyperthermia) the day following TVA. In conclusion, we showed changes in the peritoneal fluid during uneventful TVA procedures. The information provided by this research gives further insight into changes potentially caused by a TVA in abdominal fluid parameters. Further studies are necessary to determine expected standards and the duration of the changes after TVA.

Introduction Intra-abdominal hemorrhage due to blunt abdominal trauma is a major cause of trauma-related mortality. Therefore, any action taken for facilitating the diagnosis of intra-abdominal hemorrhage could save the lives of patients more effectively. The aim of this study was to determine the accuracy of focused assessment with sonography for trauma (FAST) performed by emergency physicians. Methods In this cross-sectional study from February 2011 to January 2012 at 7th Tir Hospital in Tehran (Iran), 120 patients with abdominal blunt trauma were chosen and evaluated for abdominal fluid. FAST sonography was performed for all the subjects by emergency residents and radiologists while they were blind to the other tests. Abdominal CTs, which is the gold standard, were done for all of the cases. SPSS 20.0 was used to analyze the results. Results During the study, 120 patients with abdominal blunt trauma were evaluated; the mean age of the patients was 33.0 ± 16.6 and the gender ratio was 3/1 (M/F). The results of FAST sonography by emergency physicians showed free fluid in the abdomen or pelvic spaces in 33 patients (27.5%), but this was not observed by the results of CT scans of six patients; sensitivity and specificity were 93.1 and 93.4%, respectively. As for tests performed by radiology residents, sensitivity was a bit higher (96.5%) with lower specificity (92.3%). Conclusion The results suggested that emergency physicians can use ultrasonography as a safe and reliable method in evaluating blunt abdominal trauma.

OBJECTIVE To evaluate peripheral blood and abdominal fluid variables as predictors of intestinal surgical site failure in dogs with septic peritonitis following celiotomy and closed-suction abdominal drain (CSAD) placement. DESIGN Prospective study. ANIMALS 26 dogs with septic peritonitis that underwent celiotomy and CSAD placement. PROCEDURES Abdominal fluid and blood samples were collected prior to surgery and daily thereafter until CSAD removal. Abdominal fluid was collected through the CSAD. Analysis of all samples included pH, PCO2, PO2, PCV, WBC count, and total solids, glucose, lactate, and electrolyte concentrations. Abdominal fluid samples also underwent cytologic evaluation and bacterial culture, and the volume of fluid removed through the drain was recorded daily. The blood-to-fluid glucose and lactate differences, fluid-to-blood lactate ratio and blood-to-fluid WBC and neutrophil ratios were determined daily. Dogs were categorized into 2 groups on the basis of whether they had an uneventful recovery (UR) or developed postoperative septic peritonitis (POSP). RESULTS 23 dogs had a UR and 3 developed POSP. On the third day after surgery, the abdominal fluid WBC count was significantly lower and the blood-to-fluid WBC and neutrophil ratios were significantly higher for dogs in the POSP group, compared with those for dogs in the UR group. None of the other blood and abdominal fluid variables assessed differed significantly between the 2 groups. CONCLUSIONS AND CLINICAL RELEVANCE Results failed to identify any objective predictive indicators for POSP in dogs with CSADs. Use of blood-to-fluid WBC and neutrophil ratios as predictive indicators for POSP requires further investigation.

CASE DESCRIPTION A 6-year-old neutered male domestic shorthair cat was evaluated because of signs of abdominal pain and anuria of 12 hours' duration after vehicular trauma. CLINICAL FINDINGS Lethargy, mydriasis, bradycardia, abdominal distension, and signs of pain on abdominal palpation were observed. Abdominal ultrasonography revealed moderate urinary bladder distension without evidence of free abdominal fluid; hematologic evaluation revealed leukocytosis with high BUN and serum creatinine concentrations. TREATMENT AND OUTCOME The patient was hospitalized, medical stabilization was attempted, and an indwelling urinary catheter was placed. Urinary output was < 1 mL/kg/h (< 0.45 mL/lb/h), and signs of abdominal pain persisted despite treatment. The next day, ultrasonographic examination revealed fluid in the retroperitoneal space, and ureteral rupture was suspected. Exploratory laparotomy confirmed retroperitoneal fluid accumulation; a large hematoma surrounded the right kidney and perirenal structures. An abdominal drain was placed to aid patient stabilization. Three days later, IV pyelography revealed rupture of the proximal part of the right ureter. Ureteroneocystostomy was performed with elongated cystoplasty through a Boari flap and caudal transposition of the right kidney (renal descensus). On follow-up examination 18 months after treatment, the cat was free of clinical signs, and results of ultrasonography, CBC, and serum biochemical analysis were unremarkable. CLINICAL RELEVANCE Results suggested that a Boari flap procedure with renal descensus could be a feasible alternative in the management of proximal ureteral rupture in cats, but research is needed in this area.

This is the first reported case of septic peritonitis caused by Anaerobiospirillum succiniproducens in a dog. The infection was associated with marked exfoliation of reactive mesothelial cells into the abdominal fluid mimicking neoplasia. The source of the infection was not determined but was presumed to be of gastrointestinal origin as A succiniproducens is part of the normal gastrointestinal flora of dogs. Anaerobiospirillum spp. have been previously reported as causing diarrhea and bacteremia in people, particularly if immunocompromised; however, there were no indicators for a compromised immune system in this dog.

This paper describes a thrombosis in the vena cava caudalis of a 15 year-old cat with ascites. Trauma and eventually feline enteric corona virus infection in the cat were not detected. In the intrahepatic region, a blockage of vena cava caudalis was brought to light by ultrasonographic imaging. An aspirate of abdominal fluid revealed modified transudate. Liver enzyme levels were increased in the serum sample of the cat. The levels of total oxidant status (TOS) and total antioxidant status (TAS) were elevated in the peritoneal fluid. Liver protection diet with L-carnitine, diuretic therapy and antimicrobial drugs were administrated for treatment of the cat. During the continuous treatment, the amount of abdominal fluid decreased, but never completely absorbed. L-carnitine was administered to the cat during the time of treatment, and subsequently the levels of liver enzymes decreased. However, the cat died because of recurrent ascites and persistent thrombosis. In conclusion, ultrasonographic examination was very reliable, non-invasive and highly useful diagnostic method for BCS and L-carnitine has crucial effects on the quality of life, energy metabolism and liver enzyme levels. However, the blockage of the vena cava caudalis could not completely respond to medical treatment and thrombosis should be eliminated by surgical intervention.

Prompt and accurate diagnosis of perforated appendicitis is crucial for proper and timely treatment. The appendix, however, cannot always be identified with sonography (US). We report the case of a 2-year-old child with atypical clinical presentation, and US detection of a free appendicolith as a sign of perforated appendicitis, without visualization of the appendix itself. Laparoscopy revealed a retrocecal, gangrenous, perforated appendix with autoamputation, fibrinopurulent peritonitis, and a free appendicolith within the abdominal fluid. US detection of a free appendicolith in a child is a very rare, but unequivocal sign of perforated appendicitis, which should be sought. © 2016 Wiley Periodicals, Inc.

The purpose of this study was to determine whether lactate dehydrogenase (LDH) activity in abdominal fluid could be used as a prognostic indicator in horses with colic. Lactate dehydrogenase activity was measured in 27 abdominal effusions from horses with colic presented to Murdoch University Veterinary Teaching Hospital using three different LDH test methods. Lactate in effusions was also measured in 11 of the horses. Lactate dehydrogenase activity was significantly different for each test method used—the ratio of Randox wet chemistry LDH lactate to pyruvate:Randox wet LDH pyruvate to lactate (P-L):IDEXX dry chemistry P-L was approximately 1:2:4. Lactate dehydrogenase activity in the abdominal effusions was significantly higher with all methods in the horses that died or were euthanized because of abdominal sepsis or advanced neoplasia than in those that survived after treatment for colic signs because of mechanical obstructions or nonseptic abdominal inflammation. Lactate dehydrogenase activity showed moderate-to-good correlation ( r = 0.73 to 0.86) with lactate concentration of the fluid. In conclusion, LDH activity in abdominal fluid may be a useful prognostic test in horses with colic. The test method for LDH measurement must be known and remain constant for meaningful interpretation. Significantly higher levels of LDH activity may be present in horses with colic because of sepsis or advanced neoplasia than in those with colic because of nonseptic inflammation or mechanical obstructions that may respond to treatment.

Introduction To analyze the cytomorphology and clinical correlates of pseudomyxoma peritonei (PP), a frequently fatal pathological entity defined by gelatinous ascites caused by slow but relentless accumulation of mucin produced by neoplastic glandular epithelium. Materials and methods A retrospective search of the electronic pathology data systems of three large tertiary care medical institutions revealed 41 cases from 32 patients with PP and corresponding abdominal fluid cytologic specimens. Cytologic material was available for review in 15 cases. Results The primary tumor site was appendix in 25 (78.1%) of the 32 patients, other regions of the gastrointestinal tract in 2 (6.3%) patients, and in 5 (15.6%) patients, the primary could not be entirely identified. Of the 41 cases, only 15 had available cytologic slides to review. Extracellular mucin was a constant feature in all 15 (100%) cases, being abundant in 13 cases and focal in 2 cases. Predominance of mucin-secreting neoplastic epithelial cells were observed in 10 (66.7%) and muciphages in 11 (73.4%) cases. Cytopathologic interpretations were consistent with the subsequent histopathologic diagnosis in 30 of 32 cases (93.8%). There were two false negative cases, both of which showed scant mucinous material on second review. Conclusions PP is uncommonly encountered in routine cytopathology practice. The common denominator is the presence of an often-abundant extracellular mucin. Epithelial (glandular) component is usually scant. An accurate diagnosis in a fluid specimen requires proper identification of free/extracellular mucin as well as distinguishing the often “benign-appearing” epithelial cells from reactive mesothelial cells and histiocytes.

Background and Aim. The aim of this study was to investigate the effects of demographic characteristics, biochemical parameters, amount of blood transfusion, and trauma scores on morbidity in patients with solid organ injury following trauma.Material and Method. One hundred nine patients with solid organ injury due to abdominal trauma during January 2005 and October 2015 were examined retrospectively in the General Surgery Department of Dicle University Medical Faculty. Patients’ age, gender, trauma interval time, vital status (heart rate, arterial tension, and respiratory rate), hematocrit (HCT) value, serum area aminotransferase (ALT) and aspartate aminotransferase (AST) values, presence of free abdominal fluid in USG, trauma mechanism, extra-abdominal system injuries, injured solid organs and their number, degree of injury in abdominal CT, number of blood transfusions, duration of hospital stay, time of operation (for those undergoing operation), trauma scores (ISS, RTS, Glasgow coma scale, and TRISS), and causes of morbidity and mortality were examined. In posttraumatic follow-up period, intra-abdominal hematoma infection, emboli, catheter infection, and deep vein thrombosis were monitored as factors of morbidity.Results. One hundred nine patients were followed up and treated due to isolated solid organ injury following abdominal trauma. There were 81 males (74.3%) and 28 females (25.7%), and the mean age was37.6±18.28(15–78) years. When examining the mechanism of abdominal trauma in patients, the following results were obtained: 58 (53.3%) traffic accidents (22 out-vehicle and 36 in-vehicle), 27 (24.7%) falling from a height, 14 (12.9%) assaults, 5 (4.5%) sharp object injuries, and 5 (4.5%) gunshot injuries. When evaluating 69 liver injuries scaled by CT the following was detected: 14 (20.3%) of grade I, 32 (46.4%) of grade II, 22 (31.8%) of grade III, and 1 (1.5%) of grade IV. In 63 spleen injuries scaled by CT the following was present: grade I in 21 (33.3%), grade II in 27 (42.9%), grade III in 11 (17.5%), and grade IV in 4 (6.3%). The mean length of hospital stay after trauma was 6.46 days in the medically followed patients. This ratio was 8.13 days in 22 patients with morbidity and 5.98 days in 78 patients without morbidity. There was a morbidity in 22 (22%) patients medically followed after trauma. In this study, nonoperative treatment was observed to be performed safely in solid organ injuries after trauma in case of absence of hemodynamic stability and peritoneal irritation. It has been emphasized that injury of both liver and spleen (p<0.01), high respiratory rate (p<0.01), trauma scores (GKS, ISS, RTS) (p<0.0001), and elevation of ALT AST values (p<0.01) are stimulants for morbidity that may occur during follow-up.Conclusion. Medical follow-up can be considered in patients with high grade injuries similar to patients with low-grade solid organ injury after trauma. The injury of both liver and spleen, high respiratory rate, high GCS and ISS, low RTS, and elevation of ALT AST values were found to increase morbidity again in the follow-up of these patients.

Highlights • Spontaneous hepatic rupture is a rare complication of preeclampsia and HELLP syndrome. • It carries a high maternal and perinatal mortality. • Multidisciplinary management is key to optimal outcomes. • Usual management includes perihepatic packing or angioembolization but formal lobectomy may be required in special cases., Introduction Spontaneous hepatic rupture associated with preecalmpsia or HELLP syndrome is a rare and life threatining event, only 200 cases have been reported in the literature. Presentation of case We present a case of a 31 year old female with 28 weeks of gestation that presented with acute abdominal pain, elevated blood pressure and altered liver enzymes an abdominal ultrasound that showed a subcapsular hematoma occupying the whole right lobe and free abdominal fluid, she required emergent laparotomy, C-section, hepatic packing, followed by angioembolization and finally right hepatectomy. Discussion and conslusion Spontaneous hepatic rupture due to preeclampsia or HELLP syndrome is a medical emergency, it requires a prompt and decisive treatment. Multiple treatment modalities are available, from simple hepatic packing to endovascular embolization, but in extreme situations a formal hepatectomy might be required.

Background Acute pancreatitis has been described as potential complication of both abdominal and non-abdominal surgeries. The pathogenetic mechanism underlying acute pancreatitis in spine surgery may include intraoperative hemodynamic instability causing prolonged splanchnic hypoperfusion, as well as mechanical compression of the pancreas due to scoliosis correction, with a higher risk in cases of more extended fusions, especially in young adults with lower body mass index (BMI). Case presentation We report here a case of postoperative acute pancreatitis with benign evolution in a young female patient after the first and second surgery of a two-stage correction of right thoracic idiopathic scoliosis. In December 2017, the patient underwent first-stage T4-L3 posterior arthrodesis with T7-T12 osteotomies and temporary magnetic bar. Intraoperative blood loss required massive transfusion. In the immediate postoperative period, the patient started reporting nausea/vomiting, abdominal pain at pressure, moderate meteorism, abdominal distension, hypoactive bowel sounds, and fever. Laboratory tests indicated a progressive increase in aspartate aminotransferase, alanine aminotransferase, serum amylase, lipase, phospho-creatine kinase, and reactive C-protein. A CT scan showed free abundant abdominal fluid in the hepatic, renal, pancreatic, and pelvic regions. After the diagnosis, a hypolipidic diet was initiated, and good hydration per os was maintained. After gastroenterologic consultation, somatostatin, rifaximin, and ursodehoxycholic acid were initiated and maintained for 8 days. In the following days, laboratory tests showed a slow but consistent decrease in liver and pancreatic enzymes until normalization. In January 2018, the patient underwent second-stage surgery with removal of magnetic bar, definitive posterior fusion, and instrumentation T4-L3. Laboratory tests showed a second, even more significant, increase in the amylase and lipase level and a moderate increase in the reactive C-protein. Therapy was maintained until complete normalization of amylase and lipase levels. Conclusions Early recognition of symptoms plays a key role in preventing severe morbidity after scoliosis surgery. When symptoms suggest abdominal complication, pancreatic and liver enzymes are to be evaluated for posing prompt diagnosis. Gastroenterologic consultation and eventual imaging are further steps in differential diagnosis and treatment of this rare complication.

OBJECTIVE: To estimate the frequency and amount of free peritoneal fluid in juvenile and adult dogs using the abdominal focused assessment with sonography for trauma (AFAST) abdominal fluid scoring system. DESIGN: Prospective case series. ANIMALS: Healthy, privately owned juvenile and adult dogs. PROCEDURES: Dogs undergoing routine surgical sterilization were evaluated at induction with AFAST and assigned measurements and fluid scores. A surgeon scored the degree of peritoneal fluid found during ovariohysterectomy. RESULTS: Ninety‐two dogs were enrolled (46 juveniles and 46 adults). Ninety‐three percent and 52% were AFAST positive for peritoneal fluid, respectively. The AFAST‐positive view frequency for right lateral recumbency in juveniles was diaphragmatico‐hepatic (DH) 100%, spleno‐renal (SR) 20%, cysto‐colic (CC) 40%, and hepato‐renal (HR) 20% versus adults, DH 60%, SR 20%, CC 0%, and HR 0%, respectively. The AFAST‐positive view frequency for left lateral recumbency was DH 93%, SR 44%, CC 24%, and HR 12% in juveniles, and DH 50%, SR 3%, CC 3%, and HR 10% in adults. Overall abdominal fluid scores (AFS) in juvenilles were 0 (n = 3), 1 (n = 14), 2 (n = 22), 3 (n = 6), and 4 (n = 1); and in adults, scores were 0 (n = 22), 1 (n = 18), 2 (n = 6), and 3 and 4 (n = 0). The AFS differed between adults and juveniles (P

Ultrasound (US) and laboratory testing are initial diagnostic tests for acute appendicitis. A diagnostic dilemma develops when the appendix is not visualized on US. Objective: To determine if specific US findings and/or laboratory results predict acute appendicitis when the appendix is not visualized. Methods: A prospective study was conducted on children (birth-18 yrs) presenting to the pediatric emergency department with suspected acute appendicitis who underwent right lower quadrant US. Children with previous appendectomy, US at another facility, or eloped were excluded. US findings analyzed: inflammatory changes, right lower quadrant and lower abdominal fluid, tenderness during US exam and lymph nodes. Diagnoses were confirmed via surgical pathology. Results 1252 subjects were enrolled, 60.8% (762) had appendix visualized and 39.1% (490) did not. In children where the appendix was not seen, 6.7% [33] were diagnosed with appendicitis. Among patients with a non-visualized appendix, the likelihood of appendicitis was significantly greater if: inflammatory changes in the RLQ (OR 18.0, 95% CI 4.5-72.1), CRP0.5 mg/dL (OR 2.64, 95% CI 1.0-6.8), or WBC 10 (OR 4.36, 95% CI 1.66-11.58). Duration of abdominal pain3 days was significantly less likely associated with appendicitis in this model (OR 0.34, 95% CI 0.003-0.395). Combined, the absence inflammatory changes, CRP 0.5 mg/dL, WBC 10, and pain, ≤3 days had a NPV of 94.0%. Conclusion When the appendix is not visualized on US, predictors for appendicitis include the presence of inflammatory changes in the RLQ, an elevated WBC/CRP and abdominal pain3 days.
