Spontaneous rupture of giant liver hemangioma: case report.

INTRODUCTION: Hemangioma is the most frequent benign solid tumor of the liver. It is well known that a giant liver hemangioma carries the risk of spontaneous rupture, followed by hemoperitoneum and hemorrhagic shock with possible fatal outcome. CASE OUTLINE: This is a case report of the spontaneous rupture of a giant cavernous hemangioma of the liver in an 85-year old patient.The patient was presented with abdominal pain and hemorrhagic shock. Emergency ultrasonography and computed tomography of the abdomen showed a heterogeneous ruptured solid tumor of the right liver lobe, multiple cysts in the left lobe and massive hemoperitoneum. The patient was successfully managed by immediate exploratory laparotomy, surgical enucleation of the hemangioma under intermittent inflow vascular occlusion, temporary perihepatic packing and planned second look relaparotomy. CONCLUSION: Immediate surgical procedure is indicated mandatory in unstable patients with a ruptured giant hemangioma of the liver. Surgical enucleation under intermittent inflow vascular occlusion and temporary perihepatic packing could be a life-saving procedure in those patients.

Alpha-lipoic acid upregulates antioxidant enzyme gene expression and enzymatic activity in diabetic rat kidneys through an O-GlcNAc-dependent mechanism.

PURPOSE: The combined hyperglycemia lowering and antioxidant actions of α-lipoic acid (LA) contribute to its usefulness in preventing renal injury and other diabetic complications. The precise mechanisms by which LA alters diabetic oxidative renal injury are not known. We hypothesized that LA through its hypoglycemic effect lowers O-GlcNAcylation which influences the expression and activities of antioxidant enzymes which assume important roles in preventing diabetes-induced oxidative renal injury. METHODS: An experimental model of diabetes was induced in rats by the administration of 40 mg/kg streptozotocin (STZ) intraperitoneally (i.p.) for five consecutive days. LA was applied at a dose of 10 mg/kg i.p. for 4 weeks, starting from the last day of STZ administration. RESULTS: An improved glycemic status of LA-treated diabetic rats was accompanied by a significant suppression of oxidative stress and a reduction of oxidative damage of lipids, proteins and DNA. LA treatment normalized CuZn-superoxide dismutase (SOD) and catalase activities in renal tissue of diabetic rats. These changes were allied with upregulated gene expression and lower levels of O-GlcNA glycosylation. The accompanying increase in MnSOD activity was only linked with upregulated gene expression. The observed antioxidant enzyme gene regulation was accompanied by nuclear translocation of Nuclear factor-erythroid-2-related factor 2 (Nrf2), enhanced expression of heat shock proteins (HSPs) and by reduction in O-GlcNAcylation of HSP90, HSP70, and extracellular regulated kinase and p38. CONCLUSION: α-Lipoic acid administration activates a coordinated cytoprotective response against diabetes-induced oxidative injury in kidney tissue through an O-GlcNAc-dependent mechanism.

Distal ileal endometriosis as a cause of ileus: a case report.

INTRODUCTION: Endometriosis is a benign condition affecting females of reproductive age. Although intestinal endometriosis is common, it is rarely manifested as an acute bowel obstruction secondary to ileal endometriosis. Enteric endometriosis should be considered as a differential diagnosis when assessing females of reproductive age with acute small bowel obstruction. CASE OUTLINE: A 41-year-old woman presented with symptoms and signs of an acute small bowel obstruction requiring emergency surgery. A small bowel resection was performed with end-to-end anastomosis. Histological examination demonstrated endometriosis with fibrosis and stricture of the ileal segment. This case is important to report as it highlights the diagnostic difficulty this particular condition pre sents to an emergency surgeon. CONCLUSION: In the differential diagnosis, endometriosis should be taken into consideration when assessing females of reproductive age who present with abdominal pain and small bowel obstruction.

Glissonean pedicle approach in major liver resections.

BACKGROUND/AIMS: Liver resections are still one of the most challenging operations. The aim of this study was to analyze the efficiency and safety of the intrahepatic Glissonean pedicle approach vs. classical Hilar dissection in major hepatectomies. METHODOLOGY: Thirty-four patients were assigned to the Glissonean approach (GA, n=34), while the Hilar dissection were assessed as historical control, matched for the age, gender, comorbidities and Child-Pugh score (HD, n=34). RESULTS: The GA was associated with significantly shorter surgery duration (191.18±41.10 vs. 246.62± 56.55), transection time (38.94±14.56 vs. 56.32±19.40) and ischemic duration (26.03±11.27 vs. 41.18±12.80) than HD (p<0.001 for all). The amount of blood loss was significantly lower in GA (245.59±169.39 vs. 344.71±166.25; p=0.018). The amount of blood transfusion was significantly lower in GA during surgery (322.86±102.07 vs. 414.76±135.48) as well as postoperatively than HD (246.67±5.77 vs. 336.67±120.55) (p=0.038 and p=0.026. respectively). CONCLUSIONS: Major hepatectomy can be performed more easily using the Glissonean pedicle approach than by hilar dissection. En-masse transection of pedicles, as well as hepatic veins, using endo-GIA vascular stapler could be performed safely. Liver surgeons should know the Glissonean pedicle approach.

The efficacy of three transection techniques of the liver resection: a randomized clinical trial.

BACKGROUND/AIMS: Liver resection is a demanding procedure due to the risk of massive blood loss. Different instruments for liver transection are available today. The aim of this randomized clinical trial was to analyze the efficacy of three different parenchyma transection techniques of liver resection. METHODOLOGY: A total of 60 non-cirrhotic patients undergoing hepatectomy were randomly selected for clamp crushing technique (CRUSH), ultrasonic dissection (CUSA) or bipolar device (LigaSure), n=20 in each group. All patients had liver resection under low central venous pressure anaesthesia (CVP), with ischemic preconditioning and intermittent inflow occlusion. Primary endpoints were surgery duration, transection duration, cumulative pedicle clamping time, intraoperative blood loss and blood transfusion. Secondary endpoints included the postoperative liver injury, postoperative morbidity and mortality. RESULTS: Overall surgery duration was 295 vs. 270 vs. 240min for LigaSure, CUSA and Clamp Crushing Technique, respectively. The transection duration was 85 vs. 52.5 vs. 40 minutes, respectively. These three different resection techniques of non-cirrhotic liver produced similar outcome in terms of intraoperative blood loss, blood transfusion, postoperative complications and mortality. CONCLUSIONS: The Clump Crushing Technique, CUSA and Liga Sure are equally safe for resection of non-cirrhotic liver. Liver resections can be performed safely if the entire concept is well designed and the choice of dissection device does not affect the outcome of hepatectomy.

Diagnosis of mesh infection after abdominal wall hernia surgery - role of radionuclide methods.

BACKGROUND/AIMS: The aim of this investigation was to evaluate the role of detection of late mesh infection following incisional hernia repair with radiolabeled antigranulocyte antibodies. METHODOLOGY: Mesh infection diagnoses were set up with clinical examination and laboratory analysis and confirmed by ultrasonography (US), computerized tomography (CT), scintigraphy with 99mTc-antigranulocyte antibodies and microbiological examination. RESULTS: Of the 17 patients investigated, 6 had a late mesh infection, and 11 had both mesh infection and recurrent incisional hernia. Clear clinical signs of late mesh infection were present in 13 patients. Four remaining patients had non-specific discomfort and recurrent incisional hernia without clinical manifestation of mesh infection ('silent infection'). US was positive in 12/17 patients, CT in 13/17 patients, while scintigraphy with antigranulocyte antibodies in 17/17 patients. Therefore, sensitivity of US was 71%, of CT 76% and of scintigraphy 100%. In four patients late mesh infection was confirmed exclusively by 99mTc-antigranulocyte antibody scintigraphy, while US and CT did not indicate the infection. CONCLUSIONS: According to the present results, scintigraphy with 99mTc antigranulocyte antibodies is a useful method for the detection of 'silent' abdominal wall infections after surgery, which is very important for prompt and appropriate therapy.

Decompressive laparotomy with temporary abdominal closure versus percutaneous puncture with placement of abdominal catheter in patients with abdominal compartment syndrome during acute pancreatitis: background and design of multicenter, randomised, controlled study.

BACKGROUND: Development of abdominal compartment syndrome (ACS) in patients with severe acute pancreatitis (SAP) has a strong impact on the course of disease. Number of patients with this complication increases during the years due more aggressive fluid resuscitation, much bigger proportion of patients who is treated conservatively or by minimal invasive approach, and efforts to delay open surgery. There have not been standard recommendations for a surgical or some other interventional treatment of patients who develop ACS during the SAP. The aim of DECOMPRESS study was to compare decompresive laparotomy with temporary abdominal closure and percutaneus puncture with placement of abdominal catheter in these patients. METHODS: One hundred patients with ACS will be randomly allocated to two groups: I) decompresive laparotomy with temporary abdominal closure or II) percutaneus puncture with placement of abdominal catheter. Patients will be recruited from five hospitals in Belgrade during two years period. The primary endpoint is the mortality rate within hospitalization. Secondary endpoints are time interval between intervention and resolving of organ failure and multi organ dysfunction syndrome, incidence of infectious complications and duration of hospital and ICU stay. A total sample size of 100 patients was calculated to demonstrate that decompresive laparotomy with temporary abdominal closure can reduce mortality rate from 60% to 40% with 80% power at 5% alfa. CONCLUSION: DECOMPRESS study is designed to reveal a reduction in mortality and major morbidity by using decompresive laparotomy with temporary abdominal closure in comparison with percutaneus puncture with placement of abdominal catheter in patients with ACS during SAP. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NTC00793715.

SIRS score on admission and initial concentration of IL-6 as severe acute pancreatitis outcome predictors.

BACKGROUND/AIMS: Early recognition of severe form of acute pancreatitis is important because these patients need more agressive diagnostic and therapeutical approach an can develope systemic complications such as: sepsis, coagulopathy, Acute Lung Injury (ALI), Acute Respiratory Distress Syndrome (ARDS), Multiple Organ Dysfunction Syndrome (MODS), Multiple Organ Failure (MOF). To determine role of the combination of Systemic Inflammatory Response Syndrome (SIRS) score and serum Interleukin-6 (IL-6) level on admission as predictor of illness severity and outcome of Severe Acute Pancreatitis (SAP). METHODOLOGY: We evaluated 234 patients with first onset of SAP appears in last twenty four hours. A total of 77 (33%) patients died. SIRS score and serum IL-6 concentration were measured in first hour after admission. RESULTS: In 105 patients with SIRS score 3 and higher, initial measured IL-6 levels were significantly higher than in the group of remaining 129 patients (72 +/- 67 pg/mL, vs 18 +/- 15 pg/mL). All nonsurvivals were in the first group, with SIRS score 3 and 4 and initial IL-6 concentration 113 +/- 27 pg/mL. The values of C-reactive Protein (CRP) measured after 48h, Acute Physiology and Chronic Health Evaluation (APACHE II) score on admission and Ranson score showed the similar correlation, but serum amylase level did not correlate significantly with Ranson score, IL-6 concentration and APACHE II score. CONCLUSION: The combination of SIRS score on admission and IL-6 serum concentration can be early, predictor of illness severity and outcome in SAP.

[Surgical treatment of liver injury--5-year experience].

Due to improved methods of treatment and management of hemorrhage, the mortality from liver injuries has decreased significantly over the past few decades. In spite of that, liver injuries still represent diagnostic and therapeutic challenge. This retrospective study included 197 patients surgically treated because of trauma of the liver at The Clinic for Emergency Surgery, during the period 2004-2009. The results showed significant difference in mortality rates in cases of penetrating wounds compared to blunt trauma and gunshot wounds. The severity of injury evaluated by Organ Injury Scale was significantly higher in gunshot wounds compared to blunt and penetrating trauma. The correlation of severity of injuries and mortality rates showed that the mortality is significantly lower in patients with grade 1, 2, and 3 injuries compared to grades 4 and 5 (p = 0.016). Specific complication rate was 28.4%, while mortality rate was 21.8%. The results reflect diagnostic and treatment problems, as well as the importance of multidisciplinary approach to the patients with liver trauma.

[Operative treatment of flexor pollicis longus tendon with Krackow suture, functional results--preliminary results].

INTRODUCTION: Surgical treatment of the injuried flexor tensons is the important part of hand surgery. Tendon adhesions, ruptures, joint contcatures-stifness are only one part of the problem one is faced during the tendon treatment. In spite of improvement in surgical technique and suture material, the end result of sutured flexor tendons still represent a serious problem. THE AIM: To present of operative treatment of flexor pollicis longus injury with Krakow suture technique. METHODS: All patients are treated in the first 48 hours after the accident. The regional anesthesia was performed with use of turniquet. Beside spare debridement, the reconstruction of digital nerves was done. All patients started with active and pasive movements-excercises on the first postoperative day. Follow-up was from 6 to 24 months. In evaluation of functional recovery the grip strenght, pinch strenght, range of movements of interphalangeal and metacarpophalangeal joiht and DASH score were used. RESULTS: In the last two years there were 30 patients, 25 males (83.33%) and 5 females (16.66%). Mean age was 39.8 years, ranged from 17 to 65 years. According to mechanism of injury the patients were divided in two groups: one with sharp and other with wider zone of injury. Concomitant digital nerve lesions was noticed in 15 patients (50%). CONCLUSION: the Krackow sutrue allowed early rehabilitation, which prevent tendon adhesions, enabled faster and better functional recovery.

[Surgical treatment of pancreatic injuries in severe abdominal trauma].

In spite of its low incidence, pancreatic injuries hold important place in abdominal trauma because of diagnostic difficulties, severe potential complications, therapeutic challenges, and high mortality rates. These injuries are related with specific morbidity and are very often accompanied with injuries of other organs. This retrospective study included 31 patients treated at The Clinic for Emergency Surgery of Clinical Center of Serbia during the period of 2004-2009 with intraoperativelly confirmed diagnosis of pancreatic trauma. The most common mechanism of injury was blunt trauma (83.9%). Among available diagnostic methods, abdominal ultrasound was characterized with high incidence of false-negative findings (33.3%) while for CT it was at 16.6%. The type of surgical procedure was related to degree and severity of injury. Specific complications occurred in 22.6% of patients, while mortality rate was 25.8%. The creation of unambiguous algorithms for optimal treatment of patients with pancreatic trauma require multi-centric prospective studies.

[Laparoscopy in the evaluation of blunt abdominal trauma].

Laparoscopic diagnostics provides fast, reliable, clear, and obvious information on extent and depth of abdominal organs injury with minimizing additional trauma to the patient. It is performed without any specific preparations and, if needed, it may be promptly converted into conventional laparotomy. Through use of optical equipment with various refraction angles and through variable patient positioning, laparoscopic technique enables visualization of whole abdominal cavity. In approximately 20% of cases of unclear findings, and after other performed diagnostic procedures, laparoscopy provides definitive diagnosis. Abdominal surgeons are familiar with this method, making interpretaion of the results very fast and reliable and, what is the most important, this method avoids additional trauma caused by conventional laparotomy.

[Surgical treatment of injuries of the stomach and duodenum in abdominal trauma].

Injuries of the stomach and duodenum have an important place in abdominal trauma, even though that the isolated injuries are rare. This kind of injury is most commonly associated with injuries of other abdominal organs. This retrospective study has been done at the Department of Emergency Surgery, Clinical Centre of Serbia, during the period from January 2004. until January 2009. The study included 36 patients diagnosed intraoperatively with the injury of the stomach and duodenum. The most common mechanism of harming were injuries due to blunt trauma (41.7%), the ones followed by gunshot wounds (30.5%), and the least were stab injuries (27.8%). With the majority of patients has been conducted sutures (46.3%) and serosation (30.6%) of the stomach and duodenum. In 24 (66.7%) patients on admission have been done ultrasound of the abdomen, in 6 (16.7%) abdominal CT was done, in 4 (11.1%) peritoneal lavage have been done and the x-ray of the abdomen was performed in 3 (8.3%) patients. Specific complications had 1 (2.8%) patient, while 14 (29.9%) patients have had non-specific complications. Total mortality has been 33.3%

[Hanging manuever in liver trauma].

The phylosophy of aggressive surgical approach, its complete implementation in liver trauma surgery did not appear efficient. No matter of permanenent development of diagnostic imaging methods, anesthesia, intensive therapy, medical technology and suture materials, operational theater and operative tchniques, major liver resections in trauma had mortality rate up to 60%. With introduction of computerized tomography (CT, 1981) in everyday clinical praxis and with better evaluation of trauma patients, the whole approach to liver trauma patient has been redesigned. Based on AAST-OIS classification, almost 70% of traumatized with grade I, II and III sholud be treated non-operatively, hospitally, with repeating FAST (focused abdominal ultrasound in trauma) and abdominal CT scans. The rest of traumatized patients, with grade IV and V injuries of juxtahepatic structures demand complexive surgical treatment. The modalities of surgical treatment depend on trauma mechanisms, extensivity, anatomical localisation and affection of vascular structures. Hanging Manuevr--the Method of French surgeon Belghiti bases on anterior approach in liver resection is a try for fast solution for fatal bleeding in liver trauma. It consists of placing the elastic cord throughout the anterior surface of VCI or ligamentum venosusm, of upper end of the cord is located in superior part of VCI where hepatic veins are emerging. Lower end of the cord is located in subhepatic part of VCI between 3 Glisonian pedicles. Concerning hepatic veins liver is divided in 3 sections, which derives blood in right hepatic vein RHV, middle hepatic vein MHV and left hepatic vein LHV. Belghiti proposed the usage of hanging maneuver when resecting the right liver, while the cord is placed throughout retrohepatic VCI, lower end between elements of Glisonian pedicle and upper end between hepatic veins. Complications like bleeding from caudal veins are minimal, then speed in liver resection in hemodynamic unstable and ishemic patient, defects like bleeding because compressing tapes or lesions IVC tile mobilazion of liver for conventional resection.

[Damage control surgery--our experience].

Damage control surgery represents widely implemented technique of treatment of seriously injured patients all over the world. In medical facilities with large number of seriously injured patients, type of injuries often imposes method of damage control surgery as ultimate way in treating such patients. In Emergency center from 2005-2009. 895 patients had been operated because of the trauma to the abdomen and thorax. Method of damage control surgery had been implented on 41 patients (4.6% of all operated patients). 18 patients died, and 30 seriously injured patients that hadn't been treated according to this method had died in operating room. Likewise, 11 non-trauma patients were treated according to the principles of damage control surgery because of uncontrolled bleeding. The greatest challenge today is defining criteria for choosing right patients for damage control surgery.

Planned staged reoperative necrosectomy using an abdominal zipper in the treatment of necrotizing pancreatitis.

PURPOSE: The optimal operative treatment for severe necrotizing pancreatitis (SNP) still remains controversial. This article describes the operative approach with a planned staged necrosectomy using the "zipper" technique. METHODS: Between 1996 and 2000, 35 patients with SNP were treated with this approach. The patient demographics, etiology and severity of SNP, hospital course, and outcome were recorded and comparisons of several parameters were made between the patients who survived and those who died. RESULTS: Hospital mortality was 34%. A total of 16 fistulae developed in 11 patients (31%), recurrent intra-abdominal abscesses in 4 (11%), and hemorrhaging in 5 (14%). The patients who died compared with those who survived had a higher Acute Physiology and Chronic Health Evaluation (APACHE)-II score on admission (14.5 vs 9, P < 0.001), extrapancreatic extension of necrosis more often (100% vs 65%, P = 0.02), and developed postoperative hemorrhaging more often (33% vs 4%, P = 0.038). A multivariate logistic analysis revealed an APACHE-II score of > 13 on admission (P = 0.018) and an extension of necrosis behind both paracolic gutters (P < 0.001) to both be prognostic factors for mortality. CONCLUSIONS: Severe necrotizing pancreatitis still carries significant morbidity and mortality. This surgical approach facilitates the removal of all devitalized tissue and seems to decrease the incidence of recurrent intra-abdominal infection requiring reoperation. An APACHE-II score of > or = 13 and an extension of necrosis behind both paracolic gutters was thus found to signify a worse outcome.

[Relation between cytokine IL-6 levels and the occurrence of systemic complications in patients with multiple injuries and blunt abdominal trauma]. / Odnos nivoa citokina IL6 i ucestalosti sistemskih komplikacija kod politraumatizovanih sa tupom abdominalnom traumom.

Severe trauma is the third cause of death and the first one in the most vital and young population. In USA more children die of trauma then of all other causes. Blunt abdominal trauma takes 56% cases of multiple traumas of all etiologies. Among multiple injured patients, near to 50% have some system-complications, more of 60% in the group of critically injured (ISS > 35). Cytokines play the main role in the inflammatory reaction during the early phase response on trauma. Their secretion predicts system-complications as ARDS, SIRS, even MODS. Hypothetically, level of concentration of Interleukin-6 (IL 6) can improve methods of early diagnostic procedures for detecting SIRS and MODS, when scores are still low (preclinical level), at which stages therapy is more powerful and also cheaper. This prospective study includes 35 multiple injured persons with blunt abdominal trauma (75 > ISS > 18). We have used standard diagnostic procedures. Concentration of IL 6 was detected with ELISA-test. Levels of IL 6 were significantly higher in correlation with SIRS score groups. Correlation with MODS score was not significant for the lowest scores, but IL 6 showed significant higher levels in the second and the third MODS score group.
