RESUMO
BACKGROUND: Chronic anal fissure is a common disease of the anoderm. Botulinum toxin injection has recently been recommended. However, the injection sites are still debatable. AIMS: This study aimed to assess the site-dependent efficacy of Botulinum toxin injection for chronic anal fissure healing. METHODS: Randomized clinical trial was performed, 80 patients were enrolled in two semi groups according to the site of botulinum toxin injection. Lateral sites of internal sphincter muscle were used in group 1, anterior and posterior regions were used in group 2 in lithotomy position. In this prospective study, the effect of injection site preference on the early complications (pain, infection, hematoma, incontinence) and late results (clinical fissure healing) of chronic anal fissure treatment were assessed. RESULTS: There was no statistical significant difference between the number of patients who achieved complete healing at the end of the 12th week. Postoperative pain scores were significantly lower in group 2 at the end of 1st week and they stayed lower at the end of the 2nd week. Thrombosed haemorrhoids were encountered significantly lower in group 2. CONCLUSIONS: Even though there was no statistical difference in the long term healing rate between groups 1 and 2, choosing 6 and 12 o'clock alignments of internal sphincter muscle for botox injection is more advantageous than 3 and 9 o'clock alignments in terms of better postoperative pain and lower complication rate in the early period.

The essential oil composition and in vitro antioxidant and antifungal activity of the Salvia sclarea L. from Munzur Valley in Tunceli, Turkey were evaluated in this research. The in vitro antifungal activity of ethanol, hexane and aqueous extracts of S. sclarea against pathogen fungi Epicoccum nigrum and Colletotrichum coccodes were investigated. The essential oil of aerial parts of S. sclarea was obtained by hydrodistillation and was analysed by GC and GCMS. Total antioxidant status was determined by using Rel assay diagnostics TAS assay kit (Lot.RL024) by Multiscan FC (Thermo). 33 compounds were identified representing the 85.0% of the total oil. The most abundant components (>5%) of the S. sclarea essential oils were caryophyllene oxide (24.1%), sclareol (11.5%), spathulenol (11.4%), 1H-naphtho (2,1,6) pyran (8.6%) and bcaryophyllene (5.1%). The best antifungal and antioxidant effect was seen in ethanolic S. sclarea extract. It can be said that Salvia sclerae could be used as natural antioxidant.

PROBLEM/OBJECTIVE: We compared the effects of preincisional peritonsillar infiltration of 5 ml levobupivacaine hydrochloride (50 mg/10 ml) on bleeding during surgery and pain after tonsillectomy in patients aged 16 years or older. METHODOLOGY: The study was conducted in 44 adult patients who underwent tonsillectomy. These patients were randomized to either the study group (SG) who received levobupivacaine infiltration to the peritonsillary fossae prior to surgery, or a control group (CG) treated with 0.9% sodium chloride infiltration to the peritonsillary fossae prior to incision. The volume of intraoperative bleeding was recorded. Pain was evaluated using a visual analogue scale (VAS). The first pain score was assessed immediately after arriving in the postoperative care unit. VAS scores were subsequently re-assessed 2, 4, 8, 12, and 24 hours postoperatively. The first analgesic requirement was assessed 24 hours postoperatively. RESULTS: The pain relieving effect in the levobupivacaine group was statistically significant 2, 4, 12, and 24 hours postoperatively (p ≤ 0.05), but there was no difference in VAS scores between groups at the first and 8-hour postoperative assessments. There were no differences between the two groups regarding analgesic requirements. The difference between the mean intraoperative blood loss in the SG and CG was statistically significant (p ≤ 0.05). No serious complications were observed in either group. CONCLUSION: Preincisional levobupivacaine infiltration seems to be a safe and easily applied medication for postoperative pain control, and decreased the volume of intraoperative blood loss in adult patients after tonsillectomy.

OBJECTIVE: Quality of life (QOL) assessment in patients with nasal obstruction has not been well studied. The main objectives of this study were to determine the QOL of patients after septorhinoplasty, to measure the efficacy of septorhinoplasty with a validated quality-of-life instrument--the Nasal Obstructive Symptoms Evaluation (NOSE) scale--and with the Glasgow Benefit Inventory (GBI) QOL scores comprising patient assessments of nasal function. PATIENTS AND METHODS: The patient population consisted of a consecutive series of 50 patients who underwent septorhinoplasty at the ages of 18 to 48 years between 2009 and 2011. Quality of life was assessed with the NOSE scale (pre- and postoperatively) and with GBI scores (postoperatively). Demographic data, along with patient assessments of nasal obstruction with a linear analogue scale, were recorded. RESULTS: The mean patient age was 28.3 +/- 14.6 years (age range, 18-48 years). Twenty-eight patients were male (56%) and 22 (44%) were women. Evaluation of each of the 5 items on the NOSE scale individually revealed that patients experienced improvement in all areas. In this study, there was a statistically significant fall in all five parameters (p = 0.000 < 0.05). The mean total GBI score was 34.89 +/- 22.53 and the mean general subscale score was 38.25 +/- 24.31. The mean social support score was 19.67 +/- 33.79 and the mean physical health score was 36.67 +/- 27.97. Each patient had improved QOL scores on the GBI and NOSE scales (P < 0.05). CONCLUSIONS: This study found improved QOL after rhinoplasty in Turkish adult patients. With proper pre-operative assessment and selection, excellent functional and psychosocial outcomes can be expected. NOSE and GBI are valuable tools for the assessment of benefit from nasal septal surgery for nasal obstruction and may be applicable in clinical practice.

Carotid body paragangliomas (CBP) are rare neoplasms arising from the small chemoreceptor organ in the adventitia of the common carotid bifurcation. The aim of this study is to present the diagnostic process, performed treatment and obtained results in patients with carotid body paragangliomas of the Department of Otolaryngology of Istanbul Education and Research Hospital between March 1997 and November 2008. Retrospective analysis was carried out, based on the medical documentation of 5 patients with carotid body paragangliomas (3 women and 2 men), age range 44 to 68 years with a mean of 59.6 years. Four of the patients were diagnosed and treated with Shamblin type II tumor, one of the patients with type I. Physical examination, radiological evaluation, method of the treatment and post-treatment complications were studied. The most common and single symptom was nonspecific neck mass. Preoperative diagnostic evaluation consisted of a color duplex ultrasonography, computerized tomography with contrast enhancement, magnetic resonance imaging and digital subtraction angiography. In all patients with Shamblin type I and II, blunt dissection of the tumor was conducted smoothly in the subadventitial plane. Postoperative vagus nerve and hypoglossal nerve deficit were reported in one case. Carotid body paraganglioma excision has higher risk of cranial nerve paresis and carotid artery injury, so it requires careful handling and good surgical skills to ensure complete removal.

Most of the papers published on spigelian hernia are either case reports or small retrospective series. In this prospective multicenter study, we aimed to outline the specific features of spigelian hernias and patients' characteristics more clearly. Surgeons enrolled patients to be entered into the database as they diagnosed and treated the hernias at will. The baseline and surgical outcome parameters were noted in each patient. A painful mass was the main presenting complaint in half of 34 patients. Accurate preoperative diagnosis was possible in 31 patients. Open intraperitoneal mesh repair was the preferred technique. The mean hospital stay and time until return to normal daily activities were 4.1 and 15.6 days. Although a rare condition, diagnosis of a spigelian hernia is not difficult once remembered. Its surgical repair seems to cause few complications and is very well tolerated by the patient.

BACKGROUND/AIMS: We created a study group in order to investigate the effects of splenectomy and filgrastim. Filgrastim is an immunomodulator granulocyte colony-stimulating factor (G-CSF), that affects bacterial translocation. MATERIALS AND METHODS: We created 3 study groups with 30 male Sprague-Dawley rats; the first group included sham splenectomy, the second group was splenectomy, and the third group was splenectomy+ filgrastim group. RESULTS: The mean bacterial colony count of the cecum were 2.5 x 10(9) in group 1, 1.2 x 10(10) in group 2 and 3.5 x 10(9) in group 3. The differences between these groups were accepted as statistically significant. The mean counts of the terminal ileum were 1.1 x 10(9) in group 1, 5.5 x 10(10) in group 2 and 2.5 x 10(10) in group 3. The p values of group 1-2 were 0.036 (statistically significant) and 0.123 in groups 2-3) were not statistically significant. The mean counts of the liver were 0.2 x 10(4), 1 x 10(10) and 3.4 x 10(5), respectively. In comparison of the groups the p values of the first and last 2 groups were found to be 0.047 (statistically significant). The mean counts of the mesenteric lymph node were 0.7 x 10(3), 1 x 10(10) and 0.9 x 10(6) respectively. The p values were 0.343 for the first and the last 2 groups both. As they were above 0.05, they were not statistically significant. The degrees of liver Kupffer cell hyperplasia were (+) 40%, (+2) 50% and (+3) 10% (group 1), (+) 10%, (+2) 40% and (+3) 50% (group 2), (+2) 60% and (+3) 40% (group 3) (p = 0.0039). The rates of the absence of pathology in mesenteric lymph nodes were 70% (group 1), 90% (group 2) and 100% (group 3) (p = 0.049). These findings were statistically significant. CONCLUSIONS: We found that splenectomy has activated the whole predisposing factors of bacterial translocation and created the latter itself. In addition, we showed that filgrastim, a recently widespread used G-CSF, decreases bacterial translocation significantly.

BACKGROUND/AIMS: Proper wound healing of the alimentary tract is essential for the prevention of the significant mortality and morbidity associated with complications. The effects of omentectomy on the inflammatory phase of anastomotic healing in rats were examined. METHODOLOGY: Sixty male Wistar-Albino rats that weighed about 200-220 g were used in this study. Animals were divided into three groups as colon anastomosis, colon anastomosis + partial omentectomy and colon anastomosis + total omentectomy. On the third postoperative day, all animals were sacrificed under anesthesia. Bursting pressure of anastomosis amounts and types of cells in the anastomosis, and nitric oxide, malondialdehyde, superoxide dismutase levels in the anastomosis and serum was examined. RESULTS: Bursting pressure values were 102.60 +/- 13.41 mm Hg, 105 +/- 10.80 mm Hg and 102.50 +/- 11.12 mm Hg in the colon anastomosis, colon anastomosis + partial omentectomy and colon anastomosis + total omentectomy groups, respectively (P > 0.05). A significant increase in macrophage count was found in the colon anastomosis + total omentectomy group when compared with the colon anastomosis group (P = 0.02). According to the comparisons with percentages, there was a significant difference in lymphocyte counts between colon anastomosis and colon anastomosis + total omentectomy groups (P = 0.04). The blood level of superoxide dismutase was higher in the colon anastomosis + total omentectomy group than the other two groups, and in the colon anastomosis + partial omentectomy group than the colon anastomoses group (P = 0.0001). There was a significant increase in the blood level of nitric oxide when comparing the colon anastomosis + total omentectomy group with colon anastomosis group (P = 0.02). The tissue level of malondialdehyde was higher in the colon anastomosis + total omentectomy group than the other two groups (P < 0.0001). CONCLUSIONS: Omentectomy may influence the outcome of the inflammatory phase of wound healing in rats. But systemic compensatory regulation of body can tolerate these detrimental effects and wound healing continues in its regular manner.

The use of laparoscopic surgery in peritonitis has increased rapidly. The present study examined the effects of pneumoperitoneum on bacterial clearance. Spraque-Dawley rats were divided into six groups of seven animals. In groups 1 and 4, laparotomy with a midline incision was performed and 10(9) E. coli in a volume of 1 ml inserted into the peritoneal cavity. Groups 2, 3, 5, 6 received an identical quantity of E. coli by intraperitoneal injection. Groups 3 and 6 received carbon dioxide pneumoperitoneum at a constant pressure of 5 mmHg for 60 minutes after intraperitoneal injection of E. coli. In one hour groups; the mean bacterial counts per lung from the E. coli injection with laparotomy group was significantly higher than for the E. coli injection with pneumoperitoneum group (p < 0.05). The mean bacterial counts per kidney in the E. coli injection with laparotomy group was higher compared with the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.0001). There was statistically significant difference in quantitative bacteraemia between the E. coli injection with laparotomy group and the E. coli injection or E. coli injection with pneumoperitoneum groups (p < 0.05). In four-hour groups; the mean bacterial counts of lungs and liver-spleen were significantly higher in the E. coli injection with laparotomy group than in the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.05 and p < 0.001 respectively). The quantitative bacteria was significantly higher in the E. coli injection with laparotomy group than in the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.05). This study demonstrates that pneumoperitoneum impairs the clearance of bacteria from the peritoneal cavity in an experimental model of peritonitis. However, we could not detect the deleterious effects of pneumoperitoneum compared with laparotomy.

Surgical trauma (ST) is one of the causative factor of bacterial translocation. In this study we investigated the prevention of bacterial translocation with lactulose in a surgical trauma model. The study was designed in 3 experimental groups consisting of 15 rats in each. Group 1 was sham operated controls, group 2 was ST + physiologic saline treated and group 3 was ST + lactulose treated animals. Lactulose and physiologic saline were given by oro-gastric intubation in a dose of 2 ml of 33.5% solution/d and 2 ml/d respectively starting 3 days prior to surgery. Bacterial translocation was investigated 48 hours after the operations. In sham operated controls only 1 bacterial translocation to the mesenteric lymph nodes (MLN) was observed. In the ST + physiologic saline treated group bacterial translocation to the MLN and portal venous blood (PVB) were significantly increased compared with both sham operated controls and the ST + lactulose treated group (p < 0.001). In rats with lactulose treatment the results of caecal bacterial counts showed a significant decrease in the number of gram-negative aerobes and facultative anaerobe bacteria (p < 0.01) and a significant increase in the number of lactobacilli (p < 0.001) compared to the sham operated controls. Measurement of the mucosal height showed a significant increase at the terminal ileum and the caecum compared with the sham operated controls and the surgical trauma+physiologic saline treated group (p < 0.001). We conclude that oral lactulose treatment 3 days prior to the surgical trauma, reduced the incidence of bacterial translocation to the MLN and PVB.

OBJECTIVE: To see if the prognosis and management differed in patients with carcinoma of colon and rectum above and below 65 years of age. DESIGN: Retrospective study. SETTING: University hospital, Turkey. SUBJECTS: 822 consecutive patients with colorectal carcinoma operated on between 1984 and 1994, 565 of whom were less than 65, and 257 of whom were 65 or more. MAIN OUTCOME MEASURES: Factors that affected prognosis and management. RESULTS: There were no significant differences between the two groups in mode of presentation, site and type of tumour, histological grade, incidence of curative and palliative operations, and postoperative morbidity and mortality. Obstruction and perforation were more common in the elderly group (p<0.0001). The postoperative (30 day) mortality was 3% in the younger group (20/565) and 7% in the older group (17/257). It was higher in those who were operated on as emergencies but was not significantly related to age. The actuarial five- year survival rates for older and younger patients were 33% and 45%, respectively (p<0.05). CONCLUSION: Age alone has no characteristic effect on the treatment of colorectal carcinoma.

The effects of pentoxifylline (PTX) and interferon alpha (IFN-alpha) in the prevention of strictures due to corrosive esophagitis in rats were investigated. Forty rats were randomly divided into four equal groups. Corrosive esophagitis was induced in all groups by application of 37.5% NaOH to the distal esophagus for a period of 90 s followed by saline rinse. Histopathologic damage was significantly lower in the PTX and IFN-alpha-treated groups than in the untreated group. During the study period, PTX and INF-alpha-treated animals showed a significant increase in body weight when compared to controls. However, PTX provided more significant prevention of stricture formation than IFN-alpha. In the PTX-treated group, the wall thickness and quantity of hydroxyprolin were significantly lower than in the untreated and IFN-alpha-treated groups. Stenosis index in the PTX group was significantly reduced compared to the control group. PTX prevents the stricture formation due to corrosive esophagitis in this experimental model. IFN-alpha was also shown to prevent stricture formation when considering amelioration of histopathologic damage and increase in body weight.

Recurrence of pilonidal sinus disease after surgical intervention is not a very rare problem although sophisticated reconstruction procedures have been developed. Recurrence is thought to be related to the anatomical status of the patients, i.e., depth of the intergluteal groove. Obese patients have deeper intergluteal grooves. The aim of this study was to use body mass index (BMI) as an objective indicator of obesity to determine whether there is a relationship between BMI and recurrence of pilonidal sinus disease. BMI was calculated preoperatively in 114 patients with pilonidal sinus disease who were treated by excision and Limberg flap transposition between 1996-1999 in general surgery departments of two university hospital clinics. Fifteen patients were referred to our clinics after surgical intervention carried out at other institutions. Their average BMI was calculated by using their hospital records. The mean follow-up period was 24 months (range 10-36). Six of the 114 patients (5%) had recurrence. The mean BMI of patients with and without recurrence was 29.35 and 27.415, respectively (P<0.05). The mean BMI of 15 patients referred to us because of recurrent disease was 29.41; however, that of patients with primary pilonidal sinus disease was 27.212 (P<0.05). Their BMI before their first operation was 29.30. This was also significantly higher than patients with primary disease (P<0.05). We conclude that obese patients with high BMI have a higher risk of recurrence of pilonidal sinus disease after surgical intervention.

The preventive effects of granulocyte colony-stimulating factor, cefephim, and sucralfate on bacterial translocation in experimentally induced acute pancreatitis were investigated. Forty male Wistar albino rats were used in this study. For each rat, the pancreatobiliary ductus was ligated and hence acute pancreatitis was induced. In the control group, no further procedure was performed. Meanwhile, cefephim as an antibiotic, filgrastim, which is a colony-stimulating factor, and sucralfate were given to the other groups at the specified doses. To inhibit bacterial translocation by preserving the bowel barrier, sucralfate, which is known to have a cytoprotective effect on the gastrointestinal system, was used in high doses. Cefephim 30 mg/kg per day (intramuscularly) in group II, filgrastim 10 mg/kg per day (subcutaneously) in group III, and sucralfate 50 mg/kg per day by 8-F feeding tube gavage into the stomach in group IV were given. The number of bacteria translocated into the mesenteric lymph nodes, pancreas, liver, and spleen in the control group significantly increased in comparison with the other groups (P < 0.05). The average number of leukocytes (per mm3) in the control group was significantly higher than that of other groups (P < 0.0001). Regarding the average serum amylase levels, the values of all groups clearly decreased in comparison with the control group (P < 0.0001). Although in the cefephim, filgrastim, and sucralfate groups, (+) pancreatitis was generally seen, in the control group (+++) pancreatitis was detected. Bacterial translocation to the mesenteric lymph nodes and pancreas was partially prevented by filgrastim and sucralfate, and was completely prevented by cefephim. We conclude that in the management of acute pancreatitis, the use of the prophylactic antibiotics, sucralfate and filgrastim, may be advantageous.

Diaphragmatic rupture following trauma is often an associated and missed injury. The diagnosis is difficult, so is usually made intraoperatively. Twenty-one patients with traumatic rupture of the diaphragm (TRD) who presented between 1995 and 1998 were retrospectively analysed: 12 had penetrating injuries and nine had blunt injuries. Right-sided defects exceeded left (12 vs 9). Only seven patients had signs and symptoms directly referrable to rupture of the diaphragm. All patients were operated on through a midline laparotomy. Diaphragmatic hernia was seen in six patients (28.5%); 20 (95%) patients had concomitant injuries. The liver was the most commonly injured organ (10 patients). The aim of this study was to report our experiences with TRD and review the literature. We conclude that correct preoperative diagnosis of TRD needs a high index of suspicion. It can be diagnosed intraoperatively by explorative laparotomy. Most ruptures can be repaired by the abdominal approach.

BACKGROUND/AIM: The omentum has an important role as part of peritoneal defense mechanisms. The aim of this study is to show the bactericidal activity of peritoneal fluid and the role of the omentum as a peritoneal defense mechanism in experimental animals with intra-abdominal infections. METHODS: 40 male Spraque-Dawley rats weighing between 250 and 300 g were used in this study. The rats were randomly divided into four groups consisting of 10 animals. The operative procedures were done under sterile conditions. In group I sham laparotomy was done. In group II, the distal part of the cecum was ligated, and cecum perforation was performed. In group III, total omentectomy was performed after cecal ligation and perforation. In group IV only omentectomy was performed. Baseline and 2- and 4-hour peritoneal fluid samples were taken using a Pasteur pipette during laparotomy under anesthesia. Total peritoneal cells counts, bactericidal activity of peritoneal fluid, and types of phagocytic cells in the peritoneal fluid were assessed. RESULTS: As compared with baseline values, the total peritoneal cell counts were increased at the 2nd and 4th h in all groups (p < 0.05). A significant increase was observed after 4 h as compared with 2 h in sham laparotomy, cecal ligation+perforation+omentectomy, and omentectomy groups (p < 0.05). A significant increase in the cell counts after 2 h was found in the other groups when compared to the sham laparotomy group (p = 0.0001). After 4 h, there was a significant difference between the groups, but especially prominent in the cecum ligation+perforation+omentectomy group (p = 0.0001). Proliferating colony counts of Escherichia coli and Pseudomonas Aeruginosa decreased after 2 h, and there was no proliferation in the subsequent cultures. It was observed that the macrophage counts significantly increased after 2 and 4 h as compared with baseline in intragroup assessments (p = 0.0001). In the intergroup assessment, an increase was observed in the macrophage counts at baseline and after 2 and 4 h, and this was significant in the cecal ligation+perforation+omentectomy group (p = 0.0001). In the omentectomy group, a significant decrease was observed in the macrophage counts between the 2nd and 4th h (p = 0.0001). CONCLUSION: Removal of the omentum in the presence of intra-abdominal infections causes the peripherally derived macrophages to take over the defensive role of macrophages of peritoneal origin as a compensatory mechanism, thus the peritoneal bactericidal activity against E. COLI, the major pathogen in intra-abdominal infections, does not change after omentectomy.

OBJECTIVE: To assess the safety and efficacy of diagnostic laparoscopy in patients with tuberculous peritonitis. DESIGN: Retrospective clinical study. SETTING: University hospital, Turkey. SUBJECTS: 8 patients (2 women, 6 men; mean age 26 years) who presented with tuberculous peritonitis between January 1994 and January 1996. INTERVENTION: Laparoscopy under local anaesthesia with sedation (the 4 who presented with ascites) and laparotomy (the 4 who presented with an acute abdomen). MAIN OUTCOME MEASURES: Clinical and laboratory findings, biochemical and microbiological analysis of ascites, histopathological examination of specimens, morbidity, and mortality. RESULTS: 4 patients presented with ascites, and 4 with adhesions. Ascites; adhesions between liver and diaphragm, liver and intestines, and intestines and the abdominal wall; miliary nodes on the peritoneal surface; and inflamed haemorrhagic areas on the peritoneum could all be seen at laparoscopy. One of the 8 patients who underwent laparotomy developed a spontaneous enterocutaneous fistula during the early postoperative period. Two of eight patients died, one of an early enterocutaneous fistula and the other of cor pulmonale 3 1/2 months later. The remaining 6 patients survived without complications after antituberculous medical treatment. CONCLUSIONS: Laparoscopy is a safe and accurate method of diagnosis of tuberculous peritonitis.

BACKGROUND: Malnutrition is known to affect wound healing but it is not known with certainty whether or not postoperative hyperalimentation can reverse this defect. The present study was designed to examine the effects of recombinant human growth hormone (hGH) on left colonic anastomoses in malnourished rats. METHODS: Experimental animals were allocated randomly into four groups. In groups 1 and 2 animals were fed with normal diet for 10 days before surgery. In groups 3 and 4 animals were fed with a low-protein diet. Left colonic anastomoses were performed in all animals. Following surgery, rats in groups 1 and 3 received hGH whereas rats in groups 2 and 4 were injected with saline as control. Bursting pressure and hydroxyproline levels on day 4 after operation were used to determine anastomotic healing. RESULTS: Bursting pressure was lower in the malnourished rats than those fed with normal diet (P< 0.05). Bursting pressure was higher in normally fed rats which were given hGH. No significant differences could be noted between malnourished control rats and those receiving hGH. CONCLUSION: These results suggest that hGH strengthened the left colonic anastomoses in rats fed a normal diet, but could not reverse the negative effects of malnutrition on colonic anastomoses.

BACKGROUND: Laparoscopy is increasingly used in conditions complicated by peritonitis. A theoretical concern is that carbon dioxide pneumoperitoneum may increase bacteremia. METHOD: In 60 rats peritonitis was induced by cecostomy. Animals were randomly allocated to pneumoperitoneum (PP) and control groups. Blood cultures and intraabdominal swabs were assessed. A peritonitis severity score (PSS) was computed based on histology from peritoneal biopsy. RESULTS: One hour after cecostomy neither in abdominal swabs nor in blood samples bacteria were reproduced in PP and control groups. Three hours after cecostomy the frequency of positive blood cultures was 80% and 20% in PP and control groups, respectively (p < 0.0001). Six hours after cecostomy the frequency of positive blood cultures was 100% in each group (p > 0.05). One hour after cecostomy the mean peritoneal severity score was significantly higher in the PP group than in the control group, but there was not any significant difference between groups 3 and 6 h after cecostomy. The mean peritoneal severity scores were found to be significantly increased with time when the PP groups compared with each other. CONCLUSION: In rats, pneumoperitoneum can't cause a more severe peritonitis but it does induce an increase in the rate of bacteremia within the early 6-h period of peritonitis.
