The role of colorectal stent placement in the management of acute malignant obstruction.

BACKGROUND: In recent decades, the use of colorectal stents for palliation or as a bridge to surgery in acute malignant colorectal obstruction has increased. We aimed to evaluate the technical and clinical efficacy, safety and clinical outcomes of endoscopic stenting for the relief of acute colorectal obstruction secondary to cancer. METHODS: From March 2006 to December 2012, among 100 patients with acute malignant colorectal obstruction, stenting procedures were performed on 42 patients for relief of obstruction. Uncovered self-expanding metal stents (SEMS) were placed endoscopically under fluoroscopic guidance in all patients. Using the patient database, a review was conducted to determine the effectiveness of the procedure and the short- and long-term complications. RESULTS: Stent placement was technically successful in 39/42 (92.8%) and clinically successful in 38/42 (90.4%) patients. Sixteen patients later underwent an elective surgical resection, and in 26 patients with metastatic disease or comorbidity, stent placement was palliative. Complications occurred in 10 (23.8%) patients, and the most common was tenesmus (n=3). Migration, bleeding, and recto-sigmoid perforation occurred in two patients each. Stent obstruction due to fecal impaction was seen in one case. CONCLUSION: Stent placement for colorectal obstruction is an effective and relatively safe procedure, with minor complications. It not only allows subsequent elective resection, but is also definitive for palliative treatment in patients with obstructive colorectal cancer.

Predominant causes and types of orofacial injury in children seen in the emergency department.

BACKGROUND: The aim of this study is to determine the type and cause of traumatic orofacial injuries in children up to 18 years of age. METHODS: This retrospective study involved data collected from 12055 patients that came to Istanbul University, Medical Faculty, Department of Emergency in 2011. The patients' data were evaluated with regard to age, gender, etiologic factor of the trauma, type and localization of the injury, and time interval between injury and treatment. RESULTS: A total of 1296 children in 12055 patients with orofacial trauma were evaluated. Trauma incidence was higher in boys (65%). The major etiologic factor of injury was falls (56%) and primary localization was in the frontal region (41%). The most frequent types of injury were laceration (30.1%) and hematoma (18.6%). 4% of the injuries were found in the orodental region including lips, teeth, tongue and oral mucosa of the mouth. 38% of the patients came to the emergency department within 30-60 minutes after the injury and 68% were sent home with symptomatic treatment. CONCLUSION: Considering the high percentage of orofacial traumas, effective education is necessary regarding the appropriate diagnostic approach, emergency management and prevention of traumatic dental injuries.

Falling television related child injuries in Turkey: 10-year experience.

BACKGROUND: We reviewed retrospectively TV-related injuries to determine the risk factors, type of injuries, and operative intervention(s) required in children injured by falling TVs. METHODS: This was a retrospective descriptive study conducted on 42 pediatric patients who were admitted to Istanbul University, Istanbul Medical Faculty, Emergency Surgery Department. Case notes included all demographic and injury details, TV and TV-related furniture type, mechanism of injury, Pediatric Trauma Score (PTS), Pediatric Glasgow Coma Scale (PGCS), length of hospital stay, need for intensive care unit assessments, and management plans. RESULTS: More than 65% of the children were aged 1 to 3 years. The injury rate was higher for boys (66.7%) than girls (33.3%). Of the 42 patients identified, 17 (40.5%) sustained only head injuries, with almost half of these having a definite traumatic brain injury; 6 (14.3%) had only thoracic injury, and 4 (9.5%) had only limb injury. The PGCS ranged from 3 to 15, with a mean of 7. The PTS ranged from -6 to 12, with a mean of 9. Five children (11.9%), all aged 2 years or younger, died in the hospital as a result of the TV-related injury, all sustaining head and thorax injuries, which are reflected in a significantly lower PTS and lower PGCS on admission compared with older children. TV falls on to children often occur because of unstable supports, with dressers and shelves being the most common. The most common mechanism of injury (71.4%) among all age groups was fall/tipping of furniture. Pulling the furniture onto oneself (19%) was the second most frequent mechanism of injury. CONCLUSION: Injuries related to TV falls can lead to significant morbidity and mortality in children. As they are preventable injuries, restricted activity and improved supervision of children around the TV can potentially lead to fewer incidences.

The value of potassium, pH and D-dimer levels in early diagnosis of acute mesenteric ischemia: an experimental study on rats.

INTRODUCTION: The aim of this randomized controlled experimental study was to evaluate the efficacy of potassium, pH and D-dimer levels in blood, as well as potassium and pH levels in peritoneal lavage fluid, in the early diagnosis of acute mesenteric ischemia. MATERIAL AND METHODS: This study was conducted at the Istanbul University Center of Experimental Medicine after having received approval from the Istanbul University animal testing ethics committee. Male albino Wistar rats (n = 24; 250 to 350 g) were divided into two control groups and two ischemic groups. Levels of potassium, pH, and D-dimer in blood and levels of potassium and pH in peritoneal lavage fluid were analyzed for 1 h and 2 h after the induced acute mesenteric ischemia procedure. The degree of ischemic injury was determined using the histopathological damage score in tissue samples taken from the terminal ileum. RESULTS: Ischemic groups had statistically significant differences in potassium and pH in blood and peritoneal lavage fluid compared to non-ischemic groups (p < 0.05). There was no significant difference between control and ischemic groups in terms of D-dimer and histologic grading results after 1 h (p = 0.132, p = 0.475 respectively), while there was a significant difference between control and ischemic groups after 2 h (p < 0.05). CONCLUSIONS: The levels of potassium, pH, and D-dimer could be useful in daily practice for the early diagnosis of acute mesenteric ischemia.

[Evaluation of "life-threatening" definition and negligence in children treated in the emergency surgery service burn unit (from the viewpoint of forensic medicine)]. / Acil cerrahi yanik ünitesinde tedavi edilen çocuklarda yasamsal tehlike taniminin ve ihmalin adli tip açisindan irdelenmesi.

BACKGROUND: The aim of this study is to outline the sociodemographic and traumatic characteristics of children who were referred to the Burn Unit of Emergency Service with burn injuries, to discuss the doctors' approach to these cases, and to compare the prognosis of patient groups with and without life-threat. METHODS: This epidemiological study was carried out between 14 October 2004 and 31 December 2006 and included a total of 134 pediatric patients aged between 0-18 years. A semi-structured questionnaire form was designed to obtain the information from the study population. The obtained data were statistically evaluated. RESULTS: 66.2% (n=90) of the cases were male and 33.8% (n=46) were female. The mean age of the study population was 3.9+/-4.1 years and the mean percentage of burned body area was 22.47+/-17.37. The main cause of burn was scalding with hot water, with a frequency of 77.2% (n=105). When the percentage of burn area of the body was lower than 20%, the mortality was 6.3% (n=6), whereas it was 61% (n=25) when the burn area exceeded 20% of the body (p=0.0001). While the mortality was 21.0% (n=25) among the cases with first-degree burns, it was 35.3% (n=6) among those with second- and third-degree burns (p=0.189). Mortality ratio among the cases with life-threat was higher than those without life-threat, and this difference was statistically significant (p=0.033). CONCLUSION: Extent of burn is a determinative factor for prognosis in children. Evaluation of all burn cases in children should be approached as cases of neglect/abuse; protection of these children in this manner will serve as an important practice of preventive medicine.

Femoral artery occlusion secondary to a spontaneously "migrated" hip prosthesis: case report.

A 77-year-old male patient was admitted to the hospital with a worsening acute ischemia of the left lower extremity. The patient, who had a coxarthrosis and was being followed by the orthopedic clinic, had undergone a total hip prosthesis, with a revision performed at the sixth month of its placement. The physical examination revealed the absence of the femoral, popliteal and distal pulses of the left lower extremity. The left hip movements were painful and limited in external rotation posture. Doppler ultrasonography showed an acute occlusion of the left common femoral artery due to the dislocated hip prosthesis, and right-to-left femorofemoral expanded polytetrafluoroethylene graft bypass was carried out. After successful surgery and an uneventful postoperative period with palpable femoral and popliteal pulses, the patient was put on low molecular weight heparin and referred to orthopedics once the ischemia had subsided with the intervention. Case reports regarding occlusions due to migration of total hip prosthesis are rare in the literature. The emphasis of this case report is to describe one such case.

Discussing treatment strategies for acute mechanical intestinal obstruction caused by phytobezoar: A single-center retrospective study.

BACKGROUND: This study aims to discuss management strategies regarding phytobezoar induced ileus based upon clinical results. METHODS: In the present study, between December 2012 and December 2018, a total of 25 patients who were diagnosed with phytobezoar were evaluated retrospectively. Patients who had acute mechanical intestinal obstruction due to phytobezoars at different segments of gastrointestinal (GI) tract were included in this study. The clinical data (such as clinical findings, laboratory results, radiological evaluations, treatment methods) of the patients were examined. RESULTS: Twenty five patients were included in this study. Of the 25 patients, 13 were women (52%). The median age was 60 (31-84) years, and the overall median length of the stay was 7 (2-28) days. Previous abdominal surgery had been recorded for 13 patients (72%). Two patients (8%) were followed up conservatively, whereas 20 (80%) patients had needed surgical intervention. One (4%) patient underwent surgery for distal ileal obstruction due to the pieces of bezoar that crumbled with previous endoscopic intervention. Three of the patients had complications, such as surgical site infection, wound dehiscence and paralytic ileus in the postoperative period. There were no differences between milking and gastrotomy/enterotomy groups according to the length of stay and postoperative complications. One patient died on the 13th postoperative day due to multi-organ failure. The mortality rate was 4%. CONCLUSION: Phytobezoars, which are common with many other different surgical entities, can be located at any segment of the gastrointestinal tract and may cause obstruction, strangulation and/or even perforation. Contrast-enhanced CT scan must be performed in case of suspicion and to rule out any other causes of acute mechanical intestinal obstruction. Conservative and endoscopic procedures may be useful for selected patients, but the surgical treatment may be needed for the vast majority of the patients with phytobezoar. The surgery is safe for phytobezoar if the enterotomy site is chosen wisely.

Nonoperative treatment of multiple intra-abdominal solid organ injury after blunt abdominal trauma.

BACKGROUND: A number of large series' have attempted to examine the management of blunt solid organ injuries; however, only a few studies regarding multiple injuries exist. The aim of this study is to analyze whether multiple solid organ injury affects nonoperative management (NOM) and to look for predictive factors of NOM. METHODS: All patients admitted with a diagnosis of blunt solid organ injury between January 1, 1999 and January 1, 2005 were included in this prospective observational study. Of the 468 patients who had solid organ injury, 46 patients met the inclusion criteria of multiple solid organ injuries. Presentation, mechanism of injury, injury grade, Abbreviated Injury Scale score, management, and outcomes were analyzed. Independent predictive factors of NOM failure were identified. Patients managed nonoperatively were compared with patients who had had emergent laparotomy and patients for whom NOM failed. RESULTS: Fifteen patients (33%) underwent emergency laparotomy because of hypovolemic shock that was unresponsive to aggressive resuscitation, and 31 (66%) were selected for NOM. Among the 31 patients, NOM was successful in 23 (75%). No specific organ injury combination was found to affect NOM failure. Admission lactate level [odds ratio(OR), 1.44; 95% confidence interval (CI), 1.05-1.98; p = 0.025], a drop in the hematocrit greater than 20% in the first hour after admission (OR, 1.13; 95% confidence interval CI, 1.04-1.24; p = 0.007), and solid viscus score (OR, 1.67; 95% CI, 1.03-2.80; p = 0.04) were significant independent risk factors in those patients for whom NOM failed. In logistic regression analysis, hypotension at admission (OR, 0.96; 95% CI, 0.92-0.99; p = 0.014) and transfusion in the first 6 hours after admission (OR, 1.03; 95% CI, 1.00-1.05; p = 0.015) were found to significantly affect the success rate of nonoperative management. CONCLUSION: Lactate levels at admission, solid viscus score, necessity of transfusion, crystalloid resuscitation, and a drop in the hematocrit in the first hour after admission are useful parameters for judging the failure of NOM. Although there is a higher failure rate of NOM in multiple solid organ injury, NOM can still be considered in these cases with extra caution.

Burn and vital risk criteria in industrial accidents (as forensic medicine approach).

BACKGROUND: Burn traumas resulting from industrial accidents may generate a death risk. In such cases a forensic report should be filled up. In forensic findings, the death risk which is associated with the degree of trauma, of the victim is as important as the treatment of the subject. The aim of our research was to investigate what degree of burns causes fatality and which type of industrial accidents cause them. METHODS: This research was done between the dates October 2004 and December 2006 with the descriptive epidemiology method by the evaluation of all data entered emergency surgical room- burn unit. The results of the study were analyzed with respect to its socio-demographic characteristics clinical findings of the type of burn and the type of the event which caused the burn. Categorical variables were assessed using Chi-square test, continuous variables were tested by Pearson's correlation. RESULTS: For the total 128 incidents, 69.5% (n=89) were males and 30.5% (n=39) females. 28.9% (n=37) of the incidents were industrial accidents. 48.6% (n=18) of the burns were caused by boiling water, 32.4% (n=12) due to contact by flame, 10.8% (n=4) electrocution and %8.2 (n=3) due to burns by contact with chemicals. The 19.50% (n=25) of the incidents had ended up by loss of life, 80.5% (n=103) were cured and discharged. The incidents which had resulted under 20%, the mortality rate was 1.3% (n=1), the incidents which had above 20%, the mortality rate was 49.0% (n=24) (p=0.0001). CONCLUSION: The degree of burn was found to be valuable in determining the death risk but the extent of the burned area was found to be more deterministic in assessing this particular risk.

Drain amylase monitoring for early diagnosis of anastomotic leakage in sleeve gastrectomy An animal study.

BACKGROUND: Sleeve gastrectomy(SG) is a popular bariatric surgery procedure with rare but dreaded complications. Although drain amylase levels are a reliable early predictor of anastomosis leakage in oesophagectomy and pancreaticoduodenectomy, for SG have not yet been studied. We aimed to monitor drain amylase levels to ascertain their applicability for early diagnosis of gastric leakage in SG. METHODS: Twenty-four rats were randomly divided into three groups: Group A: only laparotomy and abdominal drain; Group B: laparotomy, SG, and drain; Group C: laparotomy, SG with fistula,and drain. On postoperative days 0,1,2,3, and 4, drain lavage samples were collected to measure amylase. RESULTS: Groups were compared in pairs. Preoperative weights were not significantly different in any comparison. On postoperative days 0,1,2,3, and 4, drain amylase levels were found to be significantly lower in Group A than in Group B as well as in Group A than in Group C but were significantly higher in Group C than in Group B. For postoperative day 1, a receiver operating characteristic curve was done. Drain amylase levels over 1514 IU were statistically significant for leakage. CONCLUSIONS: Drain amylase levels were significantly high in sleeve gastrectomy with fistula. This indicates that drain amylase level monitoring might be an easy and cheap alternative for determining staple-line leakage for high risk patients with Body Mass Index(BMI)>50kg/m2 in whom we cannot use radiological imaging. KEY WORDS: Animal Experimental Study, Bariatric Surgery, Drain amylase, Sleeve gastrectomy, Staple-line leakage.

Importance of knowledge of the management of traumatic dental injuries in emergency departments.

BACKGROUND: Hospital emergency departments (EDs) are confronted with managing dental emergencies of both traumatic and non-traumatic origin. However, the literature suggests inadequate knowledge of the management of traumatic dental injuries (TDIs) among medical professionals. The aim of this study was to investigate the knowledge and attitudes regarding management of TDIs among Istanbul ED physicians. METHODS: Surveys were distributed to emergency departments (ED) directors and their physicians. The survey contained questions about their characteristics and tested their knowledge of managing dental trauma. RESULTS: A total of 126 surveys (13 ED directors and 113 physicians) were returned and included in the analysis. ED physician's knowledge of the appropriate management of crown fractures and avulsion was generally good (p=0.221), but poor for luxation injuries (p=0.0001). Physicians were more likely to have a better knowledge about permanent teeth than about primary teeth (p=0.027). CONCLUSION: Education, monitoring, improved availability of resources, and disciplinary measures in cases of poor compliance are necessary to improve TDI management in hospitals, especially among physicians.

Protective effects of pentoxifylline in small intestine after ischemia-reperfusion.

Objective This study was performed to determine the healing effects of pentoxifylline on molecular responses and protection against severe ischemic damage in the small intestine. Methods Thirty-six Wistar albino rats were divided into six groups. The superior mesenteric artery was clamped for 120 minutes, and reperfusion was performed for 60 minutes. Saline (0.4 mL), pentoxifylline (1 mg/kg), and pentoxifylline (10 mg/kg) were intraperitoneally administered to the rats in the C1, P1, and P3 groups, respectively, 60 minutes before ischemia and to the rats in the C2, P2, and P4 groups, respectively, during reperfusion onset. Malondialdehyde, myeloperoxidase, tumor necrosis factor alpha, interleukin-1 beta, and interleukin-6 in serum and tissue were measured by enzyme-linked immunosorbent assay. Intestinal ischemic injury was histopathologically evaluated by the Chiu score and immunohistochemical staining. Results All serum and tissue molecular responses were significantly blunted in the pentoxifylline-treated groups compared with the controls. Significant improvement in ischemic damage was demonstrated in the pentoxifylline-treated groups by histological grading and immunohistochemical scoring. Conclusions The protective effects of pentoxifylline were confirmed by molecular responses and histopathological examination.

Planned second-look laparoscopy in the management of acute mesenteric ischemia.

AIM: To investigate the role of second-look laparoscopy in patients with acute mesenteric ischemia (AMI). METHODS: Between January 2000 and November 2005, 71 patients were operated for the treatment of AMI. The indications for a second-look were low flow state, bowel resection and anastomosis or mesenteric thromboembolectomy performed during the first operation. Regardless of the clinical course of patients, the second-look laparoscopic examination was performed 72 h post-operatively at the bed side in the ICU or operating room. RESULTS: The average time of admission to the hospital after the initiation of symptoms was 3 d (range, 5 h-9 d). In 14 patients, laparotomy was performed. In 11 patients, small and/or large bowel necrosis was detected and initial resection and anastomosis were conducted. A low flow state was observed in two patients and superior mesenteric artery thromboembolectomy with small bowel resection was performed in one patient. In 13 patients, a second-look laparoscopic examination revealed normal bowel viability, but in one patient, intestinal necrosis was detected. In two of the patients, a third operation was necessary to correct anastomotic leakage. The overall complication rate was 42.8%, and in-hospital mortality rate was 57.1% (n = 6). CONCLUSION: Second-look laparoscopy is a minimally invasive, technically simple procedure that is performed for diagnostic as well as therapeutic purposes. The simplicity and ease of this method may encourage wider application to benefit more patients. However, the timing of a second-look procedure is unclear particularly in a patient with anastomosis.

An infrequent cause of upper gastrointestinal tract bleeding: "Dieulafoy's lesion".

BACKGROUND/AIMS: Dieulafoy's lesions are uncommon sources of upper gastrointestinal tract bleeding. Endoscopists must be aware of these lesions when evaluating patients with upper gastrointestinal tract bleeding. METHODOLOGY: The aim of this study is to analyze the results of active bleeding or recurrently bleeding Dieulafoy's lesions treated either by endoscopic injection therapy (EIT) or endoscopic band ligation (EBL). Fifteen patients who had active bleeding due to Dieulafoy's lesions were evaluated retrospectively with respect to demographic properties, comorbidities, endoscopic therapy procedures, and the success rate of the procedure. RESULTS: The incidence of Dieulafoy's lesions was 4.5% in all cases of upper gastrointestinal tract bleeding. Among the 15 patients there were nine men and six women with a median age of 52 years (25-84 years). Eleven of these lesions were located in the stomach, two were in the duodenum, and two were in the distal esophagus. Eight patients were initially treated by EIT and seven patients had EBL therapy. There was no recurrent bleeding in any of the patients treated with EBL, but five patients (62.5%) treated with EIT bled again and were treated secondarily with EBL. Two of these patients required surgical intervention and one died on the 15th day of surgery due to myocardial infarction. No endoscopy-related complications were detected. CONCLUSIONS: Endoscopic methods should be the first choice in treating bleeding Dieulafoy's lesions. Both EIT and EBL are successful methods for achieving initial hemostasis. However, EIT therapy has a higher re-bleeding rate. EBL is a safe and effective method for the treatment of bleeding Dieulafoy's lesions.

What is the clinical yield of capsule endoscopy in the management of obscure bleeding in emergency service?

BACKGROUND: The aim of this study was to investigate the efficacy of capsule endoscopy (CE) performed on patients who presented to emergency room with clinically evident gastrointestinal (GI) bleeding from unknown source and were hospitalized for follow-up. METHODS: Total of 38 patients who underwent CE and were followed-up for evaluation of clinically perceptible GI bleeding with no obvious etiology in Istanbul Medical Faculty emergency surgery department were included in the study. Patient data, which were collected between January 1, 2007 and June 1, 2015, were reviewed retrospectively. RESULTS: Of the 38 patients included in this study, 12 (32%) patients were women and 26 (68%) were men. Average age was 55.57 years (range: 20-88 years). Nine patients were using anticoagulants. Ten patients were followed-up in intensive care, and 7 patients underwent angiography. Angioembolization was performed for 1 patient who was diagnosed as having active bleed with CE. Average erythrocyte suspension replacement was 20.7 units. Total of 13 patients underwent surgery for bleeding found with CE. Eleven (34%) patients underwent double-balloon endoscopy, during which 5 patients were treated with cauterization and sclerotherapy was performed on 2. Four (18%) patients died during the study period: 2 died as result of bleeding from unknown source, 1 died of cholangiocarcinoma recurrence, and 1 died of anastomotic leakage. One patient was readmitted to hospital due to recurrence of bleeding. Nineteen (50%) patients were treated successfully based on CE findings. Diagnostic yield of CE was determined to be 78.9%. Average length of hospital stay was 32.68 days (range: 3-153 days). CONCLUSION: CE is an effective tool to detect source of GI bleeding. CE should be first choice of evaluation method for patients admitted to emergency room with obscure overt GI bleeding once radiological imaging determines absence of obstruction.

Comparison of contrast-enhanced CT with diffusion -weighted MRI in the Evaluation of patients with acute biliary pancreatitis.

OBJECTIVE: The aim of this study was to compare contrast-enhanced computed tomography with diffusion-weighted magnetic resonance imaging in the evaluation of patients with acute biliary pancreatitis. MATERIAL AND METHODS: Fifty-three patients diagnosed with acute biliary pancreatitis, between February 2012 and July 2015, were evaluated using diffusion-weighted magnetic resonance imaging and magnetic resonance cholangiopancreatography to explain the elevation of cholestasis enzymes and bilirubin levels at "stanbul University. Contrast-enhanced computed tomography imaging was applied within 8 h following first evaluation. Demographic data, severity of pancreatitis, pancreatic apparent diffusion coefficient, and computed tomography severity index were compared. The significance of the results was evaluated using Statistical Package for the Social Sciences 21.0 program. RESULTS: Median age was 53.39 (22-90) years in these 53 patients (26 were males and 27 were females). The mean Ranson criterion was 0.96 (0-4) and mean hospitalization duration was 16.02 (3-100) days. Twenty-eight patients were evaluated to have mild acute pancreatitis, whereas 16 were moderately severe and nine were severe based on the Revised Atlanta Classification. Mild pancreatitis score was 0.89, moderately severe pancreatitis score was 3.50, and severe pancreatitis score was 5.78 using the Balthazar score. Elevated C-reactive protein levels were not correlated with necrosis and the clinical severity score (p>0.05). There was no significant difference among the Balthazar score, magnetic resonance cholangiopancreatography-apparent diffusion coefficient score, and Revised Atlanta score in the evaluation of the severity of pancreatitis when the two techniques were compared. A statistically insignificant difference was found between the Balthazar score and magnetic resonance imaging results of clinically confirmed necrosis and non-necrosis patients. CONCLUSION: It can be concluded that diffusion-weighted magnetic resonance imaging might be better than contrast-enhanced computed tomography in the diagnosis of acute pancreatitis as it avoids radiation exposure as well as the development of renal failure and pancreatitis aggravation due to the use of contrast for computed tomography. These results need to be confirmed with randomized prospective controlled studies.

Ultrasound guided percutaneous cholecystostomy in high-risk patients for surgical intervention.

AIM: To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia. METHODS: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. RESULTS: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 13 x 10(3)+/-1 x 10(3) microg/L, P < 0.05 for 24 h after PC; 13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 8.3 x 10(3)+/-1.2 x 10(3) microg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2+/-18.5 mg/L vs 27.3+/-10.4 mg/L, P < 0.05 for 24 h after PC; 51.2+/-18.5 mg/L vs 5.4+/-1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38+/-0.35 centigrade vs 37.3+/-0.32 centigrade, P < 0.05 for 24 h after PC; 38+/-0.35 centigrade vs 36.9+/-0.15 centigrade, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recovered with medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter. CONCLUSION: As an alternative to surgery, percutaneous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity. Delayed cholecystectomy and ERCP, if needed, can be performed after the acute period has been resolved by percutaneous cholecystostomy.

Rupture of abdominal aortic aneurysm into sigmoid colon: a case report.

Primary aorto-colic fistula is rarely reported in the literature. Although infrequently encountered, it is an important complication since it is usually fatal unless detected. Primary aorto-colic fistula is a spontaneous rupture of abdominal aortic aneurysm into the lumen of the adjacent colon loop. Here we report a case of primary aorto-colic fistula in a 54-year old male. The fistulated sigmoid colon was repaired by end-to-end anastomosis. Despite inotropic support, the patient died of sepsis and multiorgan failure on the first postoperative day.

[A different approach to trauma scoring]. / Travma skorlamasina farkli yaklasim.

BACKGROUND: We have compared the Injury Severity Score (ISS) at admission to Emergency Surgery and Trauma Center (ES&TC) with the ISS during autopsy. Cases with ISS less than 14 (defined as preventable deaths) were evaluated and the results were compared with those in other countries. METHODS: The study was performed between January 1, 2000 and December 31, 2002 at Istanbul Medical Faculty TS&ES and the Turkish Council of Forensic Medicine. The 160 autopsies of trauma deaths which could have been performed within this three year period were evaluated. RESULTS: The average age of trauma victims in the study was 32,9+/-15,6 (r=1-79); the majority of victims were males 78,1% (n=125). In four autopsies (3%) ISS were rated as "preventable death" (ISS < or =14). The severely injured (ISS: 16-66) patients with lower survival rates were 96% (n=155). In addition, one case (1%) had an ISS score of 75. In clinical evaluations, ISS scores were found to be between 16-66 (68%), 75 (20%, n=32), and < or =14 (12%; n=19). CONCLUSION: Although it is widely used, difficulties in the applications of ISS still exist. Alcohol, drug, pregnancy and the presence of underlying diseases are the factors contributing to death but not being reflected by ISS. Moreover a difficulty exists in the evaluation of anatomical injuries which are not accompanied by physiological changes. ISS should be improved according to updates. In this way, evaluation of clinics' care quality and standardization of trauma centers can be done more accurately.
