RESUMO
Background The diagnosis of acute mesenteric ischemia is variable. Early diagnosis is important for reducing the mortality and morbidity rates. Aim This experimental study aims to investigate the diagnostic utility of D-dimer and neopterin as a marker for the early stage of acute mesenteric ischemia caused by occlusion of superior mesenteric artery. Methods The levels of D-dimer and neopterin were measured using an animal acute mesenteric ischemia model in 21 male rabbits. Superior mesenteric artery occlusion (Group 1, n = 14) and control (Group 2, n = 7) groups were identified. Blood samples at different times are collected from each rabbits. Blood samples from superior mesenteric artery occlusion group were taken 30 min after anesthesia but before laparotomy, 1, 2, and 3 h after superior mesenteric artery ligation. Blood samples from control group were taken 1 h before, 1 and 3 h after anesthesia and laparotomy. The D-dimer and neopterin levels of each blood sample were measured. Results The probability of acute mesenteric ischemia was found to be 36 times higher when the D-dimer level was over 0.125 ng/L, whereas the probability was 19.2 times higher when the neopterin level was over 1.25 nmol/L. Conclusions In this experimental study, the combined elevation of two significant markers, D-dimer and neopterin, may be helpful for the early diagnosis of acute mesenteric ischemia.

PURPOSE: The study aims to evaluate the changes between body mass index (BMI) and ghrelin levels after laparoscopic Nissen fundoplication (LNF). METHODS: Twenty-four consecutive patients with gastroesophageal reflux disease who were scheduled for LNF consented to participate in the study. The participants' age, sex, preoperative (phase 0), postoperative 1st week (phase 1) and postoperative 4th week (phase 2) dysphagia scores, plasma ghrelin levels, and BMI were recorded. RESULTS: Compared to the preoperative level (phase 0), ghrelin was decreased in both phase 1 and phase 2. A strong correlation in the changes in the ghrelin values and BMI between phase 0 and phase 2 was detected. There was a strong, statistically significant difference in the changes in the BMI values between phase 1 and phase 2. CONCLUSIONS: Total plication of the fundus impairs its ghrelin-secreting functions for up to 4 weeks and is accompanied by weight loss.

BACKGROUND: We aimed in this study to investigate the relationship between Injury Severity Score (ISS) and transfusion strategies required during medical intervention in patients wounded by high kinetic energy (HKE) gunshot, and to analyze end-mode mortality. METHODS: The medical data of patients were included in the study. We evaluated whether there was any significant correlation in terms of demographic characteristics, HKE weapon type, ISSs, and transfusion strategy options and transfusion requirements. RESULTS: Causes of mortality in cases resulting in mortality during hospitalization were evaluated. One hundred and eight consecutive patients were included in the study. All patients except one were male, with an average age of 25 years. 64.8% of them were injured by long-barreled firearms, whereas 35.2% were injured by explosives. Average ISS was 13.9. ISS values for the patients with and without transfusion were 16 (5-48) and 9 (3-36), respectively. Causes of mortality were evaluated in terms of systemic inflammatory response syndrome (SIRS), sepsis, and multiorgan dysfunction syndrome (MODS). DISCUSSION: It was determined that there was a significant correlation between increase in ISS values in cases with HKE weapon wounds and their transfusion requirements, whereas this requirement was independent of the ISS value in cases with explosive wounds.

BACKGROUND: The diagnosis of acute appendicitis, even for experienced surgeons, can sometimes be complex. A delay in diagnosis increases the complication rate. This experimental study aimed to investigate the suitability and significance of neopterin as a marker for acute appendicitis. METHODS: The levels of neopterin were measured using an acute appendicitis animal model in 35 New Zealand male rabbits. They were divided into 5 groups as Group 1= control; Group 2= sham; and Groups 3 (12-hour); 4 (24-hour); and 5 (48-hour) (based on the elapsed time period before their appendectomies). The neopterin levels of each group were measured by neopterin enzyme immunoassay kit in blood samples (taken before the appendectomies in Groups 3, 4 and 5). RESULTS: For the diagnosis of acute appendicitis, the optimal cut-off point was 34.475 nmol/L. The probability of acute appendicitis was found to be 4.667 times higher when the neopterin level was greater than 34.475 nmol/L. CONCLUSION: This study was an experimental animal study; however, it provides valuable clues useful in clinical assessment. Neopterin seems to have great potential as a new diagnostic marker for the diagnosis of acute appendicitis.

Our study reviewed nine patients who were treated with the VAC™ Abdominal Dressing System after suffering pelvic fractures and soft tissue loss after high-energy pelvic trauma. Between March 2008 and August 2009, our clinic treated nine patients with complicated perineal injuries from high-energy pelvic trauma with multiple irrigation and debridement procedures and broad-spectrum antibiotics. Protective ostomies were created for all nine patients. Required interventions were made for associated injuries, and VAC™ application was started. All patients were male, with an average age of 24·3 (range 21-32) years, and a mean injury severity score of 36·4 (range 16-59). Wound diameters ranged from 15 to 30 cm, and wound depths ranged from 5 to 25 cm. The injuries included one traumatic bilateral hemipelvectomy, and three unilateral and two bilateral lower extremity amputations. Intensive care unit length of stay averaged 12 (6-19) days, and average hospital length of stay was 44·12 (31-64) days. Beginning at an average of day 17 (±5·9 days) post-injury, wound cultures detected no bacterial colonisation. One patient died on the sixth day after injury from septic complications. Two patients' wounds were closed by primary closure, and six patients' wounds were closed by split thickness grafts after an average of 31·4 (17-50) days. Optimal treatment of high-energy perineal injuries requires early and extensive debridement and rich irrigation. The application of the VAC™ system as temporary coverage of large complex wounds in the pelvic region enhances wound healing and facilitates an early grafting process.

Hardy and colleagues carried out 'Renal autotransplantation' for the first time in 1963 to treat severe ureter injury and it has evolved as a method used for complex treatment of trauma, renal artery diseases or ureteral stenosis. In case of proximal ureter injury, approximately 2/3 of which is iatrogenic, if the end-to-end anastomosis is not possible, renal autotransplantation, ileal ureter interposition or nephrectomy are alternative treatments. As technology advances, the use of ureterorenoscopy (URS) increases and in parallel with this iatrogenic injuries that occur during the process have increased as well. These types of injuries are generally in form of simple perforations (2-6%), but from time to time ureter avulsions are also observed (0.3%). In this article, a case is presented where renal autotransplantation is made following development of ureter avulsion during ureterorenoscopy process carried out due to right ureteral calculi and treatment options are discussed in the light of literatures.

BACKGROUND: Tramadol is an analgesic drug, and its mechanism of action is believed to be mediated by the mu-opioid receptor. A further action of tramadol has been identified as blocking the reuptake of serotonin (5-HT). One of the most recently identified subtypes of 5-HT receptor is the 5-HT7 receptor. Thus, the authors aimed to examine the potential role of serotonergic descending bulbospinal pathways and spinal 5-HT7 receptors compared with that of the 5-HT2A and 5-HT3 receptors in the antinociceptive and antihyperalgesic effects of tramadol and its major active metabolite O-desmethyltramadol (M1) on phasic and postoperative pain models. METHODS: Nociception was assessed by the radiant heat tail-flick and plantar incision test in male Balb-C mice (25-30 g). The serotonergic pathways were lesioned with an intrathecal injection of 5,7-dihydroxytryptamine. The selective 5-HT7, 5-HT2, and 5-HT3 antagonists; SB-269970 and SB-258719; ketanserin and ondansetron were given intrathecally. RESULTS: Systemically administered tramadol and M1 produced antinociceptive and antihyperalgesic effects. The antinociceptive effects of both tramadol and M1 were significantly diminished in 5-HT-lesioned mice. Intrathecal injection of SB-269970 (10 microg) and SB-258719 (20 microg) blocked both tramadol- and M1-induced antinociceptive and antihyperalgesic effects. Ketanserin (20 mumicrog) and ondansetron (20 microg) were unable to reverse the antinociceptive and antihyperalgesic effects of tramadol and M1. CONCLUSIONS: These findings suggest that the descending serotonergic pathways and spinal 5-HT7 receptors play a crucial role in the antinociceptive and antihyperalgesic effects of tramadol and M1.

BACKGROUND: The increase in terrorist attacks has brought a profound and new knowledge of blast injuries. In order to improve our knowledge regarding the mechanisms of blast injuries, we analyzed the effects of shock waves. METHODS: 100 g TNT and 1000 g C4 were detonated and recorded by high-speed camera. Blast wind, shock wave and shrapnel speeds were calculated, and final condition of the target was examined. RESULTS: A flash ball appeared first followed by the shock wave. Finally, blast wind occurred and shrapnel was distributed. The macroscopic structure of targets was not affected by the shock wave but was affected by shrapnel and blast wind. Shock waves created a transparent ballistic gel inside the target mat by changing its microscopic structure. The speed of the shock wave was 6482-7194 m/sn and shrapnel speed was 1420-1752 m/sn. CONCLUSION: Shock waves especially affect the air-filled organs and cause lung injury, acute respiratory distress syndrome, and intestinal and eardrum perforation. Blast wind destroys targets due to its high speed and high density. The main cause of mortality is shrapnel injury. The high temperature created by the explosion causes thermal injuries. Being informed of the mechanisms of blast injuries will assist in providing better treatment. Additionally, consideration of all mechanisms of blast injuries will facilitate lower mortality and morbidity rates.

INTRODUCTION: In this study, we investigated D-dimer serum level as a diagnostic parameter for acute appendicitis. MATERIALS AND METHODS: Forty-nine patients were enrolled in the study. Patients were classified according to age; sex; duration between the beginning of pain and referral to a hospital or clinic; Alvarado scores; and in physical examination, presence of muscular defense, the number of leukocytes, preoperative ultrasonography, and D-dimer levels of histopathologic study groups were analyzed. RESULTS: Of the patients enrolled in the study, 26.5% were females and 73.5% males. The average age was 21 years (range, 16-38 years) and 81.7% acute appendicitis (AA). According the duration of pain, 63.2% of the patients were referred to the hospital within the first 24 hours, 26.5% of the patients were referred to the hospital within 24 to 48 hours, and 10.3% were referred to the hospital within a period of more than 48 hours. No statistically significant difference was determined regarding D-dimer levels between the histopathologic study groups (P > .05). Alvarado scores lower than 7 were found in 36.7% and 7 or higher in 63.3% of the patients. There was no statistically significant difference related with D-dimer levels between histopathologic study groups (P > .05). The ratio of cases with a number of leukocytes below the upper limit were determined respectively as 32.7% and 67.3%, and no statistically significant difference was found regarding d-dimer levels between histopathologic study groups (P > .05). CONCLUSION: Increased D-dimer levels should not be considered as a diagnostic parameter in diagnosis of acute appendicitis.

PURPOSE: Acute appendicitis is one of the most common surgical emergencies. Diagnosis is usually made depending on the presenting history, clinical evaluation, and laboratory tests. The aim of this study was to investigate the role of urinary 5-hydroxyindoleacetic acid (U-5-HIAA) in the early diagnosis of acute appendicitis. METHODS: Thirty-five pigmented male rabbits were divided into 5 groups. Group 1 is the control (n = 7); group 2 is the sham (n = 10). The appendix was ligated from its base, and an appendectomy was performed after 12, 24, 36 hours in group 3 (n = 7), group 4 (n = 7), and group 5 (n = 7), respectively. Spot urine samples were obtained for U-5-HIAA determination, and appendectomy tissues were examined histopathologically. RESULTS: Acute appendicitis was diagnosed in all animals in group 3, group 4, and group 5, and the mean levels of U-5-HIAA in group 3 were higher than in the other groups. The mean of U-5-HIAA levels between animals with appendicitis and those without showed a significant difference (P = .003). The U-5-HIAA cutoff point of 4.15 mg/g creatinine had a sensitivity of 85%, a specificity of 64.29%, and an accuracy of 76% (area under curve = 0.805) for acute appendicitis. The probability of acute appendicitis is found to be 10, 2 times more when the U-5-HIAA level is greater than 4.15 mg/g creatinine. CONCLUSION: We have concluded that spot U-5-HIAA level increases significantly in the early stages of acute appendicitis.

Diaphragmatic rupture occurs in 0.8% to 3.6% of patients after blunt or penetrating thoracoabdominal trauma, and the preoperative diagnosis is difficult. The diagnosis of traumatic diaphragmatic rupture may be made on initial presentation or at any time later. Right-sided diaphragmatic rupture is rare and occurs in approximately 5% to 20% of all diaphragmatic disruptions. The incidence of herniation of the intra-abdominal organs into the pleural cavity is also low, observed in only about 19% of right-sided diaphragmatic ruptures. We present a case of right-sided traumatic rupture of the diaphragm diagnosed 15 years after the initial blunt trauma. A 22-year-old male patient fell 15 years before and was symptom-free since then. He was referred to our hospital with the signs of herniation of the right diaphragm, which was manifested in the chest x-rays. The definite diagnosis was made through thoracoabdominal computed tomography. The diaphragmatic rupture was repaired via abdominal approach.

Lightning strike is an unusual form of trauma in terms of being one of the leading causes of death from natural phenomenon. Lightning strike can cause severe damage to many systems and results in a high mortality. The most common cause of death in the lightning strike victim is cardiopulmonary arrest. The most vulnerable subjects for lightning strike are individuals who work in open fields, farmers, and swimmers. The cardiac and neurological injuries are the most serious injuries. Burns, tinnitus, blindness, and secondary blunt trauma have also been reported. Gastrointestinal complications have been documented very rarely. In this study, we present a case of gastric perforation after lightning strike. No report related to gastric perforation caused by lightning strike has been identified in the literature.

Negative pressure wound closure system facilitates wound closure via wound contraction. In this article, we report a successful application of thoracic negative pressure wound closure system to fill the thoracic defect, control infection, and expand the lung in a 35-year-old male patient with threerib defect, lung parenchyma injury, empyema, left complete pneumothorax, and visible pericardium after gunshot injury. The excellent result obtained in our patient demonstrates that negative pressure wound closure system is a good choice for treating high-energy thoracic injuries by reducing wound infection and enabling early wound closure.
RESUMO
Stump viscera caused by an incomplete operation can present the same symptoms as before the first operation. Furthermore, as an acute clinical event, these incomplete resections may sometimes cause acute abdomen and may need emergency surgical intervention. A 34-year-old woman with a history of laparoscopic cholecystectomy 5 days before was admitted with acute abdominal symptoms. Abdominal exploration revealed that she had undergone incomplete resection of the gallbladder. Another patient, a 21-year-old man, was admitted with complaints of fluid drainage from his appendectomy incision scar. He was diagnosed as having enterocutaneous fistula. Abdominal exploration revealed a stump appendix fistulizing to the abdominal wall. The third patient was a 32-year-old man with an appendectomy scar who was admitted with complaints of acute appendicitis. The patient was diagnosed as having acute appendicitis and underwent an appendectomy. A stump appendix was removed during the operation. Surgeons should be aware of stump pathologies and keep in mind a possible incomplete operation to prevent delayed diagnosis and treatment.

PURPOSE: Anastomotic leaks following intestinal operations may cause devastating effects on patients. Ischemia may also occur at the intestinal walls in the presence of strangulations. In this study, we examined the effects of human recombinant (Hr)-epidermal growth factor (EGF) given at a single intramural dose into the intestinal walls and daily intraperitoneal cavity on ischemia and the healing process of anastomosis. MATERIALS AND METHODS: Sixteen male New Zeland white rabbits were randomly divided into four groups (n = 4 in each group). In Group 1, two different segments of ileum were identified and, then, transected and the free ends were sutured each other. In the other groups, ischemia was induced by ligating the mesenteric vascular arcade. After the ischemic induction, Group 2 received intramural injections of %0.9 saline, Group 3 received intramural injections of a single dose of EGF, and Group 4 received intramural and intraperitoneal injections of EGF. Bursting pressures and tissue hydroxyproline levels were analyzed. Necrosis, fibroblastic activity, collagen deposition and neovascularization were also studied. RESULTS: The mean levels of bursting pressures in Group 4 (148.6 ± 25.3 mmHg) were higher than Group 2 (70 ± 21.5 mmHg) (p = 0.001). The mean level of bursting pressures was not statistically significant between Group 1 (170.1 ± 35 mmHg) and Group 4 (p = 0.073). Hydroxyproline levels in Group 2 were lower than Groups 3 and 4. There was a statistically significant difference in the mucosal ischemia, mucosal healing and degree of adhesion, but not in the mural anastomotic healing among the groups. CONCLUSIONS: Intramural injection with daily intraperitoneal administration of low-dose EGF enhances the bursting pressure and collagen accumulation in ischemic anastomosis, improving many histological variables associated with ischemic intestinal anastomosis.

BACKGROUND/AIMS: Heterotopy is defined as abnormal localization of well-differentiated tissue. Heterotopic tissues usually tend to be asymptomatic and noncomplicated but sometimes may cause serious clinical problems. Malignancy potential is the most important issue in this clinical entity. In this study we reviewed medical records of 24 patients with heterotopic tissues. METHODS: Between 1995-2004, 24 patients with heterotopic tissues who were diagnosed during gastrointestinal system or abdominal wall surgery or upper gastrointestinal endoscopy were included in this study. Patients' medical data were retrospectively reviewed. RESULTS: Sixteen patients with heterotopy were younger than 30 years and eight patients were older than 30 years. Nineteen (0.21%) heterotopic tissues were diagnosed in 8,945 patients who underwent gastrointestinal system surgery or upper gastrointestinal endoscopy, whereas five (0.21%) heterotopic tissues were diagnosed in 2,320 patients who underwent abdominal wall surgery. Overall, 24 (0.21%) heterotopic tissues were found in a total of 11,265 patients. The majority were pancreatic heterotopy, followed in decreasing order by gastric, adrenal and osseous heterotopy. In patients who underwent gastrointestinal surgery-endoscopy, pain was the main symptom (n=13)(68.4%), followed by dyspepsia (n=3)(15.7%) and vomiting- nausea (n=2)(10.5%). The main symptom in patients who underwent abdominal wall surgery was palpable mass. heterotopic tissues presented as wall thickening in 13, polypoid mass in five and whole solitary mass or intraparenchymal lesion in six patients. CONCLUSION: Although incidence of heterotopic tissues is low, in case of its suspicion or diagnosis, early treatment should be performed by surgical or endoscopic resection or patients must be followed up carefully due to risk of malignancy.

BACKGROUND: The aim of the present study was to investigate the diagnostic value of alkaline phosphatase (ALP) intestine-isomerase, plasma lactate dehydrogenase (LDH), and D-dimer levels in acute mesenteric ischemia. METHODS: Thirty Wistar rats were divided into 5 groups of 6 rats each. In Group 1, blood samples were obtained to determine normal parameter levels. In the sham group, Group 2, blood samples were obtained following laparotomy. In Group 3, blood samples were obtained 2 hours after ligation. In Groups 4 and 5, blood samples were obtained at 4 and 6 hours after ligation, respectively. Ischemic damage was assessed using a pathological scoring system. Blood samples were analyzed for hourly changes in parameters. RESULTS: No statistically significant difference in D-dimer levels was found between ischemia groups (p=0.337). A statistically significant difference in LDH levels was found between the control group, Group 1, and Group 4 (p=0.018). ALP intestine-isomerase enzyme levels were not statistically significant in other groups (p=0.077). CONCLUSION: Findings indicate that plasma LDH levels higher than 1900 IU/L may be a useful marker in the early diagnosis of acute mesenteric obstruction. However, ALP intestine-isomerase enzyme and D-dimer plasma levels were not found to contribute to the diagnosis.

BACKGROUND: Treatment of colorectal injuries (CRIs) remains a significant cause of morbidity and mortality. The aim of the present study was to analyze treatment trends of Turkish surgeons and effects of the American Association for the Surgery of Trauma (AAST), Injury Severity (ISS), and Penetrating Abdominal Trauma Index (PATI) scoring systems on decision-making processes and clinical outcomes. METHODS: Data regarding high velocity missile (HVM)-related CRIs were retrospectively gathered. Four patient groups were included: Group 1 (stoma), Group 2 (no stoma in primary surgery), Group 2a (conversion to stoma in secondary surgery), and Group 2b (remaining Group 2 patients). RESULTS: Groups 1, 2, 2a, and 2b included 39 (66%), 20 (34%), 6 (30%), and 14 (70%) casualties, respectively. Ostomies were performed in casualties with significantly higher AAST scores (p<0.001). However, PATI and ISS scores were not decisive factors in the performance of ostomy (p=0.61; p=0.28, respectively). Ostomy rates of civilian and military surgeons were 62% and 68%, respectively (p=0.47). Receiver operating characteristic (ROC) analysis showed that AAST score was a more accurate guide for performing ostomy, with sensitivity and specificity rates of 80% and 92.9%, respectively. CONCLUSION: Clinical significance of diversion in HVM-related CRIs remains. Stomas were associated with lower complication rates and significantly higher AAST colon/rectum injury scores.

BACKGROUND/AIM: Postoperative pain control constitutes a major problem and studies have focused on reducing opioid requirements using regional techniques. We aimed to investigate the efficacy of wound infiltration with lornoxicam on postoperative pain control following thyroidectomy. MATERIALS AND METHODS: In this prospective, randomized-controlled study, 80 patients scheduled for thyroidectomy were randomly assigned to 2 groups. After the thyroidectomy was performed, patients in group I underwent wound infiltration with 4 mg of lornoxicam and patients in group II received the same amount of saline. Rescue analgesia was provided with additional doses oflornoxicam delivered by an on-demand patient-controlled analgesia device. Total analgesic consumption during the postoperative 24 h, and pain intensities assessed using a visual analog scale score at 0, 2, 4, 8, 12 and 24 h postoperatively were recorded. RESULTS: Pain scores during the postoperative 24 h were slightly lower in group I than in group II, but the difference was not significant (P > 0.05). The mean analgesic consumption was 8.87 ± 1.87 mg and 10.33 ± 1.25 mg in groups I and II, respectively (P > 0.05). CONCLUSION: Wound infiltration with lornoxicam neither improved postoperative pain control nor decreased total analgesic consumption.

Prevention of secondary infection is currently the main goal of treatment for acute necrotizing pancreatitis. Colon was considered as the main origin of secondary infection. Our aim was to investigate whether prophylactic total colectomy would reduce the rate of bacterial translocation and infection of pancreatic necrosis. Forty-two Sprague-Dawley rats were used. Pancreatitis was created by ductal infusion of sodium taurocholate. Rats were divided into four groups: group-1, laparotomy + pancreatic ductal infusion of saline; group-2, laparotomy + pancreatic ductal infusion of sodium taurocholate; group-3, total colectomy + pancreatic ductal infusion of saline; and group-4, total colectomy + pancreatic ductal infusion of sodium taurocholate. Forty-eight hours later, tissue and blood samples were collected for microbiological and histopathological analysis. Total colectomy caused small bowel bacterial overgrowth with gram-negative and gram-positive microorganisms. Bacterial count of gram-negative rods in the small intestine and pancreatic tissue in rats with colectomy and acute pancreatitis were significantly higher than in rats with acute pancreatitis only (group-2 versus group-4; small bowel, p = <0.001; pancreas, p = 0.002). Significant correlation was found between proximal small bowel bacterial overgrowth and pancreatic infection (r = 0,836, p = 0.001). In acute pancreatitis, prophylactic total colectomy (which can mimic colonic cleansing and reduction of colonic flora) induces small bowel bacterial overgrowth, which is associated with increased bacterial translocation to the pancreas.
