RESUMO
AIM: Data regarding the operative management of presacral tumours present various dilemmas due to their rarity and heterogeneous nature. The aim of this study was to evaluate the management strategy, factors associated with operative morbidity and long-term postoperative outcomes in a large group of patients undergoing surgery for presacral tumours. METHOD: This study was designed as a multicentre retrospective cohort study. Records of patients who underwent surgery for presacral tumours at 10 tertiary colorectal centres between 1996 and 2017 were evaluated. RESULTS: One hundred and twenty seven patients (44 men) with a mean age of 46 years and body mass index of 27 kg/m2 were included. Fifty eight per cent of the patients had low sacral lesions (below S3). The operative approaches were transabdominal (17%), transsacral (65%) and abdominosacral (17%). The postoperative morbidity was 19%. Thirty per cent of the patients had a malignant tumour. Longer duration of symptoms (p = 0.001), higher American Society of Anesthesiologists score (p = 0.01), abdominosacral operations (p = 0.0001) and presacral tumours located above S3 (p = 0.004) were associated with an increased risk of postoperative morbidity. Overall long-term postoperative recurrence and mortality were 6% and 5%, respectively, within a 3-year mean follow-up period in patients with presacral malignant tumours. CONCLUSION: Reduced physical condition, omission of symptoms prior to surgery, combined resections and high sacral tumours are the risk factors associated with postoperative complications in patients undergoing surgery for presacral tumours. Meticulous planning of the operation and intensified perioperative care may improve the outcomes in high-risk patients.
RESUMO
INTRODUCTION: Hemorrhage is a challenging complication of pelvic surgery. This study aimed to analyze the causes, management, and factors associated with morbidity in patients experiencing major pelvic hemorrhage during complex abdominopelvic surgery. METHODS: Patients who had major intraoperative pelvic hemorrhage during complex abdominopelvic surgery at 11 tertiary referral centers between 1997 and 2017 were included. Patient characteristics, management strategies to control bleeding, short- and long-term postoperative outcomes were evaluated retrospectively. RESULTS: There were 120 patients with a mean age of 56.6 ± 2.4 years and a mean BMI of 28.3 ± 1 kg/m2. While 104 (95%) of the patients were operated for malignancy, 16 (5%) of the patients had surgery for a benign disease. The most common bleeding site was the presacral venous plexus 90 (75%). Major pelvic hemorrhage was managed simultaneously in 114 (95%) patients. Electrocauterization 27 (23%), pelvic packing 26 (22%), suturing 7 (6%), thumbtacks application 7 (6%), muscle welding 4 (4%), use of energy devices 2 (2%), and topical hemostatic agents 2 (2%) were the management tools. Combined techniques were used in 43 (36%) patients. Short-term morbidity and mortality rates were 48 (40%) and 2 (2%), respectively. High preoperative CRP levels (p = 0.04), history of preoperative radiotherapy (p = 0.04), longer bleeding time (p = 0.006), and increased blood transfusion (p = 0.005) were the factors associated with postoperative morbidity. CONCLUSION: Postoperative morbidity related to major pelvic hemorrhage can be reduced by optimizing the risk factors. Prehabilitation prior to surgery to moderate inflammatory status and prompt action with proper technique to control major pelvic hemorrhage can prevent excessive blood loss in complex abdominopelvic surgery.

BACKGROUND: Long-term bowel dysfunction after resection for rectal cancer, known as low anterior resection syndrome (LARS), is observed in many patients. The LARS score was developed to assess this syndrome and its impact on the quality of life in Danish patients. Recently versions in English and many other languages have been validated. The aim of this study was to validate the Turkish translation of the LARS score in patients who have undergone treatment for rectal cancer. METHODS: Rectal cancer patients who underwent low anterior resection in May 2000- May 2018 in three Turkish centers received the LARS score questionnaire, the European Organisation for Research and Treatment Of Cancer Core Quality of Life questionnaire [Ed.11] (EORTC QLQ-C30), and a single ad hoc quality of life question. The test-retest reliability of the LARS score was evaluated by asking a randomly selected subgroup of patients to repeat the assessment of the LARS score 2 to 4 weeks after their initial response. RESULTS: A total of 326 patients were reviewed and contacted for the study, and 222 (68%) were eligible for the analyses (129 males, 93 females, median age 64 years [range:24-87 years, IQR = 14]) There was a strong association between the LARS score and quality of life (p < 0.01) and the test-retest reliability was high. The intraclass correlation coefficient was 0.78 (95% CI 0.73-0.83) for the whole study group and 0.79 (95% CI 0.68-0.87) for the subgroup, indicating strong reliability. CONCLUSIONS: The Turkish translation of the LARS score has psychometric properties comparable with previously published results in similar studies. The Turkish version of the LARS score can be considered a valid and reliable tool for measuring LARS in Turkish rectal cancer patients. CLINICAL TRIAL REGISTRATION: NCT05289531.

AIM: To investigate the anal component of the anogenital Human Papillomavirus (HPV) related disease during surveillance of patients treated for cervical intraepithelial neoplasia (CIN). METHODS: Patients were analyzed within two groups according to the histopathological examination of the cervical biopsies: Low-Grade Squamous Intraepithelial Lesion (LSIL) and High-Grade Squamous Intraepithelial Lesion (HSIL) groups. Anal specimens were also collected in the first-year follow-up visit. RESULTS: All patients had cervical high-risk HPV (HR HPV) infection at admission. At the first-year follow-up, positive HR HPVs were found in 47% of cervical samples. Despite this clearance, the anal HPV infection rate after the first year was 42.5% and 39.6% in LSIL and HSIL groups. Amongst the HSIL group, anal HR HPV positivity was observed in 29.6% of cases without any cervical HPV infection. CONCLUSION: A group of women cured of high-grade lesions have ongoing anal HPV infection. It is reasonable to propose that detecting anal HPV could impact the patient's treatment process. Therefore, prospective studies are needed to investigate this group of women's clinical outcomes and define the clearance rate of cervical HPV infection when anal HPV persists.
RESUMO
BACKGROUND: Currently, the lateral internal sphincterotomy is the treatment of choice for a chronic anal fissure (CAF). However, the length of the internal sphincter incision varies, due to lack of standardization. Insufficient length increases the risk of recurrence. To compare a new ultra-modified internal sphincterotomy (UMIS) to the closed lateral internal sphincterotomy (CLIS) for treating CAF, based on internal anal sphincter function and postoperative complications. The primary endpoint was continence after UMIS. The secondary outcomes were CAF healing complications, visual analog scale pain scores, and sphincter pressures. METHODS: This was a prospective, randomized, controlled trial (block randomization method). 200 patients with CAFs were randomly assigned to receive either UMIS (n = 100) or the closed lateral internal sphincterotomy (CLIS) (n = 100). Follow-up was 2 years. RESULTS: All (100%) patients in both groups showed clinical improvement at 1 month post-surgery. Recurrences were accompanied by deteriorations in Cleveland Clinic Florida Fecal Incontinence scores at 12 months and 2 years (P < .05). The groups showed significant differences in fissure healing rates and pain scores. After 1 and 2 years, incontinence rates were significantly higher, and patient satisfaction scores were significantly lower in the CLIS group than the UMIS group (P < .05). CONCLUSION: UMIS provided a faster healing rate and fewer side effects than the CLIS for treating CAFs. These results might lead to a standardized treatment among surgeons.

Aim: The current standard treatment of locally advanced rectal carcinoma is total mesorectal excision and postoperative adjuvant chemotherapy after neoadjuvant concurrent chemoradiotherapy (NCRT). Many studies have shown that pathological complete response (pCR) is an important prognostic factor for patients receiving NCRT. Many studies have therefore been conducted to increase pCR rates by changing the perioperative treatment strategies. Prolonging the chemotherapy time may be a reasonable way to increase the effectiveness of NCRT, pCR, and survival rates. We investigated whether neoadjuvant consolidation chemotherapy had an effect on tumor response and survival. Methods: The data of 163 patients diagnosed with locally advanced rectal carcinoma were evaluated. The data of 107 patients (Group 1) who were radiologically T3-T4 and/or N+ and received chemotherapy after NCRT until their operations were compared with the data of 56 patients (Group 2) who were operated after NCRT. Results: Group 1 patients had tumor and node downstaging. Their pCR was found significantly higher than in Group 2 (p = 0.005). In Group 1 patients with T3, pCR was significantly higher than for those with T4. The elapsed time between NCRT and surgery was significantly longer in patients with pCR (respectively, p = 0.012 and p = 0.008). Conclusion: Neoadjuvant consolidation chemotherapy after NCRT is a safe approach that can lead to higher pathological complete response rates. The time until surgery with neoadjuvant consolidation chemotherapy may provide the chance to follow the patient without surgery in addition to increasing pCR.
RESUMO
INTRODUCTION: This pilot study aimed to document our results of treating anorectal abscesses with drainage plus loose seton for possible coexisting high fistulas or drainage plus fistulotomy for low tracts at the same operation. METHODS: Drainage plus fistulotomy were performed only in cases with subcutaneous mucosa, intersphincteric, or apparently low transsphincteric fistula tracts. For all other cases with high transsphincteric fistula or those with questionable sphincter involvement, a loose seton was placed through the tract. Drainage only was carried out in 17 patients. RESULTS: Twenty-three patients underwent drainage plus loose seton. Drainage plus fistulotomy were performed in four cases. None of the patients developed recurrent abscess during a follow-up of 12 months. Not surprisingly, the incontinence scores were similar pre and post-operatively (p=0.564). Only minor complications occurred in 4 cases (14.8 percent). Secondary interventions following loose seton were carried out in 13 patients (48.1 percent). At 12 months, drainage only was followed by 10 recurrences (58.8 percent; p<0.0001, compared with concomitant surgery). CONCLUSION: Concomitant loose seton treatment of high fistula tracts associated with anorectal abscess prevents abscess recurrence without significant complications or disturbance of continence. Concomitant fistulotomy for associated low fistulas also aids in the same clinical outcome. Concomitant fistula treatment with the loose seton may suffice in treating the whole disease process in selected cases. Even in patients with high fistula tracts, the loose seton makes fistula surgery simpler with a mature tract. Abscess recurrence is high after drainage only.

BACKGROUND: The aim of this study was to assess whether subjective global assessment (SGA) is useful in identifying malnutrition and outcomes in the intensive care unit (ICU). METHODS: After obtaining institutional approval, 124 consenting patients were enrolled in this study. Patients were evaluated at admission using clinical data, SGA, height, weight, triceps skinfold thickness (TSF), mid-arm circumference (MAC), Acute Physiology and Chronic Health Evaluation (APACHE II), and Simplified Acute Physiologic Score (SAPS). Patients were classified as well nourished, moderately malnourished, or severely malnourished with SGA. RESULTS: According to SGA, 62% (n = 77) of the patients were classified as well nourished, 26% (n = 33) as moderately malnourished, and 11% (n = 14) as severely malnourished. Body weight, body mass index (BMI), MAC, TSF, and mid-arm muscle circumference (MAMC) were lower, whereas APACHE II and SAPS II scores and mortality were higher in the malnourished groups compared with the well-nourished group. The SGA rating correlated significantly with age, body weight, percentage of weight loss, serum albumin level, APACHE II and SAPS II scores, and mortality. Anthropometrics data were correlated with SGA. Mortality rate was correlated with high APACHE II score, SAPS II score, days in the ICU and low BMI, MAMC, and serum albumin level. CONCLUSIONS: The results support that SGA is simple and may predict the patient's outcomes in the ICU.

BACKGROUND: Mirizzi syndrome is a rare complication of cholelithiasis, characterized by the narrowing of the common hepatic duct as a result of mechanical compression and/or inflammation due to biliary calculus impacted in the infundibula of the gallbladder or in the cystic duct. In this study, we aimed to describe the clinical presentations, investigations, operative details, and complications of seven patients who underwent endoscopic retrograde cholangiopancreatography and were finally diagnosed with Mirizzi syndrome in our center. METHOD: We performed a retrospective analysis of the records of 7 patients with Mirizzi syndrome who underwent endoscopic retrograde cholangiopancreatography. RESULTS: The incidence of Mirizzi syndrome was 1.07% of 656 patients given endoscopic retrograde cholangiopancreatography. Ultrasonography was able to diagnose one case. Endoscopic retrograde cholangiopancreatography suggested the diagnosis in five cases and helped further in the management of these patients. Four patients had cholecystectomy and T-tube placement, and two had cholecystectomy and choledochoduodenostomy. One patient with type I Mirizzi syndrome according to the Csendes classification successfully underwent laparoscopic cholecystectomy. CONCLUSIONS: In the study, the incidence of Mirizzi syndrome was 1.07% of patients who underwent endoscopic retrograde cholangiopancreatography. Preoperative diagnosis of Mirizzi syndrome by endoscopic retrograde cholangiopancreatography is important to prevent complications.

The systemic inflammatory response of the body to invading microorganisms, called sepsis, leads to profound activation of the complement (C3 and C4) system. The present study was conducted to compare the use of serum C3 and C4 levels with C-reactive protein (CRP) and thrombocyte and leukocyte counts in differentiating patients with systemic inflammatory response syndrome (SIRS) from those with sepsis. Over a 6-mo period, all patients with SIRS or sepsis who stayed in the intensive care unit for >24 h were enrolled in the study. At admission, each patient's clinical status was recorded, and blood was taken for laboratory analysis (complete blood count, CRP, C3, and C4). A total of 58 patients with SIRS and 41 patients with sepsis were admitted to the study. The mean+/-SD thrombocyte count was found to be significantly lower in septic patients (179,975+/-95,615) than in those with SIRS (243,165+/-123,706) (P=.005); no difference in plasma concentrations of CRP and levels of C3 and C4 was noted between groups. The thrombocyte count was determined to be the most reliable parameter for differentiating between SIRS and sepsis (highest area under the curve=0.656).

OBJECTIVES: To evaluate the effects of certolizumab, a pegylated monoclonal antibody to tumor necrosis factor α (TNF-α), on experimentally induced acute pancreatitis. METHODS: Healthy Wistar Albino male rats (n = 36) were randomly divided into 4 groups (9 rats in each group): group 1, control group; group 2, certolizumab group; group 3, cerulein group; and group 4, cerulein + certolizumab group. Acute edematous pancreatitis was induced via intraperitoneal injection of 80-µg/kg cerulein (20 µg/kg, 4 times at 1-hour intervals) in groups 3 and 4. Certolizumab (10 µg) was intraperitoneally administered in groups 2 and 4. Serum levels of amylase, lipase, TNF-α, and lactate dehydrogenase were evaluated. Histopathology and immunohistochemistry of the pancreatic tissue for assessing the activities of malondialdehyde, myeloperoxidase, TNF-α, and caspase-3 were also performed after 72 hours. RESULTS: Certolizumab treatment significantly decreased the serum levels of amylase, lipase, and lactate dehydrogenase. Histopathological edema, hemorrhage, parenchymal necrosis, and infiltration scores were also decreased, along with a decrease in malondialdehyde, myeloperoxidase, TNF-α, and caspase-3 activities. CONCLUSION: This study suggests that certolizumab is a beneficial treatment mode for reducing the severity of acute pancreatitis.

BACKGROUND: Mesenteric ischemia-reperfusion (I/R) is a well-known event causing both local and remote organ injuries, including the lungs. Recently, several studies indicated that activated leukocyte-endothelial cell interactions play an important role in the mechanisms of these injuries. As a natural inhibitor of serine proteases, antithrombin was shown previously to attenuate the tissue damage after local I/R in several organ systems. Here, we examined the effects of antithrombin on pulmonary injury after mesenteric I/R. METHODS: Wistar albino rats underwent median laparotomy and were randomized into 3 groups: (1) sham-operated control (n = 12), (2) 60 minutes of mesenteric ischemia and 3 hours of reperfusion (n = 12), and (3) antithrombin-pretreated (250 U/kg) group before the I/R (n = 12). At the end of reperfusion, animals were killed and neutrophil sequestration, myeloperoxidase (MPO) activity, and Evans blue dye extravasation in the lung parenchyma were assessed and compared. RESULTS: There was a statistically significant increase in the quantity of Evans blue dye concentration, leukocyte sequestration, and MPO activity in the I/R group when compared with the control group. The pretreatment of animals with antithrombin significantly decreased the pulmonary injury characterized by increased Evans blue dye extravasation, leukocyte sequestration, and MPO activity. CONCLUSION: The data of the present study suggest that mesenteric ischemia and reperfusion induces pulmonary injury characterized by activated neutrophil sequestration and increased microvascular leakage in the lungs. A significant attenuation of intestinal I/R-related lung injury with the use of antithrombin concentrate warrants further studies to elucidate the potential role of this natural serine protease inhibitor in clinical settings.

BACKGROUND: The aim of the current prospective study was to examine the prognostic value of APACHE II, APACHE III (Acute Physiology and Chronic Health Evakuation II and III) and SOFA (Sepsis-related Organ Failure Assessment) scores and platelet counts in septic and nonseptic patients hospitalized and treated in ICU units. METHODS: One hundred and twenty ICU patients were included in this study. Patients were grouped as septic survivors, septic nonsurvivors, nonseptic survivors and nonseptic nonsurvivors. The SOFA, APACHE II and III scores, and platelet counts were recorded at the admission in the ICU units and discharge.from the hospital. RESULTS: Patients were grouped as septic survivors (n=42), septic nonsurvivors (n=14), nonseptic survivors (n=48) and nonseptic nonsurvivors (n=16). The highest SOFA, APACHE II and III scores and the lowest platelet counts were observed in septic nonsurvivors when compared with the other patient groups. All score values and platelet counts were found to be significant in prediction of mortality in septic patients. CONCLUSIONS: According to our results obtained in septic and non-septic patients, we concluded that SOFA, APACHE II and III scores and platelet counts might be used in the prediction of mortality in septic patients.

BACKGROUND: Hepatic hydatid cysts rarely invade portal veins causing portal cavernomatosis as a secondary complication. CASE REPORT: We report the case of a patient with direct invasion of the right portal vein by hydatid cysts causing portal cavernomatosis diagnosed via magnetic resonance imaging (MRI). CONCLUSION: The presented case highlights the useful application of MRI with T2-weighted images and gadolinium-enhanced T1-weighted images in the diagnosis of hepatic hydatid lesions presenting with a rare complication of portal cavernomatosis.
RESUMO
AIM: We aimed to investigate the effects of Tempol on local organ damage in an experimental acute pancreatitis model. METHODS: This experimental study was conducted on 40 male Wistar- albino rats. The animals were randomly allocated into four groups: (i) Sham-operated group, laparotomies and cannulations of the pancreatic duct without acute necrotizing pancreatitis (ANP) (n=10); (ii) Sham + Tempol group, identical to group 1 except for intravenous tempol treatment for 4 hours (n = 10); (iii) ANP group, glycodeoxycholic acid was infused into the pancreatic duct and cerulein was infused intravenously for 6 hours for development of ANP (n=10); and (iv) ANP + Tempol treated group, in addition to the procedure in group 3, rats were administered tempol intravenously for 4 hours (n = 10). Injury of the pancreas was evaluated histopathologically. Malondialdehyde and myeloperoxidase levels of the pancreatic tissue, blood gas analysis, leukocyte and hematocrit levels were measured. Wet/dry weight of pancreatic tissue was also measured. RESULTS: Serum amylase levels, pancreatic tissue malondialdehyde and myeloperoxidase levels, wet/dry weight ratio, pancreatic edema, acinar necrosis, fat necrosis and hemorrhage, inflammation and perivascular infiltration were significantly lower in the ANP + Tempol group compared with the ANP group. CONCLUSION: Tempol infusion reduced local organ damage due to acute necrotizing pancreatitis in this experimental study. These findings demonstrate that tempol has protective effects on local organ damage due to acute necrotizing pancreatitis in rats.

The limited efficacy of standard medical therapies for inflammatory bowel diseases has resulted in a continuing search for alternative treatments. Growth hormone (GH) has shown to have mutagenic and proliferative effects on intestinal cells. This study was designed to identify the effect of growth hormone on trinitrobenzene slfonic acid-induced colitis (TNBSIC) in rats. This study was carried out on 30 rats, divided in 3 groups: group 1: TNBSIC+ GH, group 2: TNBSIC, group 3: saline enema. Colitis was induced in male Sprague-Dawley rats (200 g-250 g) by intracolonic installation of 2, 4, 6-trinitrobenzene sulphonic acid in 50% ethanol. GH treatment has been started and continued throughout the study after inducing colitis. All rats were killed after 5 weeks and colonic segments were examined histopathologically. Microscopic and macroscopic damage scores were caulculated. Intestinal damage scores were found higher in Goups II when compared with treatment group (P < 0.05). There was no damage in group 3 as expected. Both macroscopic and microscopic scores were highest in group 2 (P < 0.05). The myloperoxidase activity was found lower comparing to group 2 (P < 0.05). In conclusion, growth hormone replacement had protective effects against colonic inflammation while reducing intestinal damage on TNB-induced colitis.

BACKGROUND: Antithrombin III is known as the most important natural inhibitor of thrombin activity and has been shown to attenuate local harmful effects of ischemia-reperfusion injury in many organs. In recent animal studies, delaying effect of remote organ ischemia-reperfusion injury on healing of intestinal anastomoses has been demonstrated. In this study, we investigated whether antithrombin III reduces deleterious systemic effects of ischemia-reperfusion injury on healing of colonic anastomoses in rats. METHODS: Anastomosis of the left colon was performed in 24 rats that were divided into three groups: sham operated control (group I, n = 8), 30 minutes of intestinal ischemia-reperfusion by superior mesenteric artery occlusion (group II, n = 8), antithrombin III treated group (250 U/kg before and after the ischemia-reperfusion, group III, n = 8). On postoperative day 6, all animals were sacrificed, and bursting pressure and tissue hydroxyproline content of the anastomoses were assessed and compared. RESULTS: On postoperative day 6 the mean bursting pressures were 149.6 +/- 4.8, 69.8 +/- 13.5, and 121.8 +/- 8.7 mm Hg for groups I, II, and III, respectively (P = 0.000). Mean tissue hydroxyproline concentration values were 389.5 +/- 29.6, 263.1 +/- 10.0, and 376.0 +/- 33.8 microg/mg for groups I, II, III respectively (P = 0.005). CONCLUSIONS: This study showed that, antithrombin III treatment significantly prevented the delaying effect of remote organ ischemia-reperfusion injury on anastomotic healing in the colon. Further clinical studies are needed to clarify whether antithrombin may be a useful therapeutic agent to increase the safety of the anastomosis during particular operations where remote organ ischemia-reperfusion injury takes place.

OBJECTIVE: Different methods have been used to assess nutritional status in hospitalized patients, and there is no agreement as to which index best reflects nutritional status. The aim of this study was to determine the prevalence of malnutrition and compare the Subjective Global Assessment, Nutrition Risk Index, and non-nutritional factors in hospitalized patients. METHODS: This prospective study was done in the teaching hospital of Pamukkale University Medical School, Denizli, Turkey. Two hundred fifty-one consecutive patients hospitalized in medical and surgical wards were studied. On admission, the Subjective Global Assessment, Nutrition Risk Index, anthropometric measurements, and laboratory data were assessed. Differences between independent groups were assessed with Student's t test and one-way analysis of variance. Spearman's rank correlation coefficients were calculated for associations between scores and variables. Agreement between two assessment methods was analyzed by the K statistic. RESULTS: On admission, 30% of patients were malnourished according to the Subjective Global Assessment and 36% according to the Nutrition Risk Index. Body weight, albumin, lymphocyte, total cholesterol, and anthropometric data were lower in the malnourished patients according to both assessments (P < 0.01). Body weight loss and length of stay were higher in the malnourished patients according to both assessments (P < 0.01). Body weight, anthropometric data, albumin, and total cholesterol correlated inversely with nutritional status according to both techniques. Concordance was observed in 203 of the 251 (81%) patients with both assessments (K = 0.57, P = 0.000). CONCLUSIONS: Both tests correlated with each other with respect to age, length of stay, and anthropometric and laboratory data in hospitalized patients. Therefore, these two techniques can be used for nutritional assessment in hospitalized patients.

BACKGROUND: Infected necrosis in acute pancreatitis is the main factor in determining the prognosis of the disease. Early and accurate diagnosis of infected pancreatic necrosis might decrease mortality. The aim of the present study is to identify a reliable marker for the onset infection in three different experimentally induced pancreatitis models. METHODS: Ninety female Wistar albino rats were randomly divided into nine groups. In three different experimental models, including cerulein induced acute oedematous pancreatitis (AEP), sterile pancreatic necrosis due to taurocholate-induced acute pancreatitis (SPN) and infected pancreatic necrosis taurocholate-induced acute pancreatitis (IPN). Serum levels of procalcitonin (PCT), C-reactive protein (CRP), tumour necrosis factor a (TNF-alpha), interleukin 6 (IL-6) and interleukin 8 (IL-8), amylase were measured. The degree of pancreatic damage also evaluated pathologically. RESULTS: Procalcitonin levels were increased significantly in AEP, SPN and IPN compared to control groups (P < 0.05). PCT and IL-6 level were the highest in the IPN group (P < 0.05). Serum amylase, CRP, TNF-alpha, IL-2, and IL-8 levels were similar between IPN and SPN groups (P > 0.05), but higher than in other groups. The results of histological evaluation also correlated with the advent of the disease. CONCLUSION: Procalcitonin and IL-6 acts as reliable acute phase reactant in an experimental model of AEP, SPN and IPN in the rat. PCT and IL-6 combination might be surrogate marker of infected pancreatic necrosis and should be preferred to other markers assay especially in severe pancreatitis.
