A Troublesome Complication of Hydatid Cysts; Intra-Abdominal Rupture: A 10-Year Study from a High-Volume Center.

Background: Hydatid cyst is a parasitic infection, often caused by Echinococcus granulosus. Although it is classified as a benign disease, cyst ruptures in the abdomen can be fatal. Ruptures occur spontaneously or after trauma. We aimed to report data from patients who underwent emergency surgery due to spontaneous intra-abdominal hydatid cyst rupture. Methods: Upon a retrospective review of the records at Department of General Surgery, Faculty of Medicine, Harran University, Sanliurfa, Turkey, we found that 34 cases were operated on due to hydatid cyst rupture between January 2012 and October 2022. All patients were operated on in an emergency, and partial cystectomy, intra-abdominal irrigation, and drainage were performed using laparotomy. The patients were evaluated in terms of age, sex, symptoms, radiological findings, laboratory results, intraoperative findings, and postoperative follow-ups. Results: Twenty-two (64.7%) female and 12 (35.3%) male patients were enrolled. The mean age was 39.1 (±17.58) years. All patients experienced spontaneous rupture. The ruptured cyst was found in the liver in 32 patients (94%), the spleen in 1 patient (3%), and the pelvis in 1 patient (3%). The diagnosis was determined using ultrasonography in 12 (35.3%) patients, computed tomography in 21 (61.8%) patients, and magnetic resonance imaging in 1 (2.9%) patient. All patients exhibited acute abdomen and leukocytosis. The average length of hospital stay was 5.14 (±1.37) days. Conclusion: Hydatid cyst rupture should be considered in cases of acute abdomen, particularly in regions where the disease is endemic, as in our region. The ruptured hydatid cyst was primarily observed in the liver (94.11% of cases).

Does one of the two most commonly used scoring systems have a decisive advantage over the other in diagnosing acute appendicitis in pregnant women?

This study aimed to compare the accuracy and reliability of Alvarado Score (AS) and Appendicitis Inflammatory Response Score (AIRS) in pregnant women undergoing surgery for acute appendicitis (AA). The files of 53 pregnant women with a diagnosis of AA who underwent surgery in our clinic between February 2014 and December 2018 were examined retrospectively. The patients were divided into 3 groups as follows: first trimester between 0 and 14 weeks, second trimester between 15 and 28 weeks, and third trimester between 29 and 42 weeks. The AS and AIRS values were calculated according to preoperative physical examination and laboratory results. The mean age of the patients was 28.58 (18-44) years. According to the pathology results, appendicitis was detected in 16 of 23 patients in the first trimester, in 22 of 25 patients in the second trimester, and in 2 of 5 patients in the third trimester. The AIRS was ≥ 9 in 9 patients and the AS was ≥ 7 in 19 of the 23 patients in the 1st trimester, while the AIRS was ≥ 9 in 11 patients and the AS was ≥ 7 in 19 of the 25 patients in the 2nd trimester. However, in the 3rd trimester, the AIRS was ≥ 9 in 2 patients and AS was ≥ 7 in 4 of the 5 patients. In conclusion, when the data obtained from the present study were evaluated, it was determined that both AS and AIRS are effective methods for diagnosing AA in pregnant women.

Changes in cuff pressure of endotracheal tube during laparoscopic and open abdominal surgery.

BACKGROUND: The purpose of this study was to investigate endotracheal tube cuff pressure alteration in patients during laparoscopic cholecystectomy surgery. METHODS: Forty patients with ASA I-II physical status, who were scheduled for elective laparoscopic (group I) or open abdominal surgery (group II) were enrolled in the study. Tracheal intubation was always performed by an experienced anesthesiologist. The endotracheal tube cuff was inflated with air through a 10-ml syringe. The cuff was connected to a manometer. The endotracheal cuff pressure was registered every 5 min after tracheal intubation. At the time of discharge from the Post-Anesthesia Care Unit (PACU) and 12 h after tracheal extubation, patients were asked about their laryngotracheal condition by an independent observer who was uninformed of the patient allocation groups. We investigated laryngotracheal complaints such as sore throat, dysphasia, and hoarseness. RESULTS: The endotracheal cuff pressures in group I were significantly higher than those in the group II at all time points studied (P < 0.05). The endotracheal cuff pressures exceeded the critical pressure of 30 cmH(2)O after 5 min in the group I (intra-abdominal pneumoperitoneum was started). The incidence of sore throat was higher in group I than in group II in the PACU and at 12 h. CONCLUSION: This study indicates that the CO(2) pneumoperitoneum and Trendelenburg position used during laparoscopy increase endotracheal cuff pressure and lead to discomfort in the postoperative patient. Measurement of endotracheal cuff pressure is a simple and inexpensive procedure and should be applied in patients under going laparoscopic surgery.

Protective and therapeutic effects of licorice in rats with acute tubular necrosis.

OBJECTIVES: Various protective and therapeutic effects such as antioxidant, anti-inflammatory, anticancer, antihistaminic, and antibacterial effects have been depicted for licorice. However, its biological effects in the kidney are still not clear. Therefore, we aimed to investigate the efficiency of licorice in rats with gentamicin (GM)-induced acute tubular necrosis. DESIGN AND METHODS: Rats were randomized into the control group (only saline for 12 days), licorice group (licorice for 12 days), GM group (GM for 12 days), GM + licorice group, and licorice-treated GM group (licorice for 12 days after taking GM for 12 days). Blood urea, creatinine, and uric acid levels were measured and histopathological analyses of the kidneys were performed. The oxidative side of oxidant-antioxidant balance was evaluated by detecting lipid peroxidation (LPO) and total peroxide levels, and antioxidative side was determined by measuring total antioxidant capacity (TAC) and reduced glutathione (GSH) levels in plasma and kidney tissues. RESULTS: The oxidant-antioxidant balance seemed to be shifted to the oxidative side in the GM group when compared with the control and GM + licorice groups. In GM group, biochemical profiles showed a remarkable increase in blood uric acid, urea, and creatinine levels, and depletion of renal tissue and plasma TAC and GSH levels. In addition, histopathologic studies revealed severe acute tubular necrosis, congestion, and hyaline casts, verifying GM-induced nephrotoxicity. Licorice was effective in reduction of blood urea, creatinine, and uric acid levels, and also effective in decreasing the tubular necrosis score. Licorice treatment also significantly reduced LPO and total peroxide levels, and increased TAC and GSH levels in both renal tissue and blood. Moreover, these changes in rats subjected to the combined therapy (GM + licorice) were significantly less than those of GM group. CONCLUSIONS: Licorice ameliorates GM-induced nephrotoxicity and oxidative damage by scavenging oxygen free radicals, decreasing LPO, and improving antioxidant defense.

Co-occurrence of diaphragmatic and serratus anterior muscle hydatidosis: an unusual localization.

BACKGROUND: With hydatid cyst, the skeletal muscles and diaphragm are rarely affected, and hepatic and pulmonary hydatid cysts are far more common. We report a case with an unusual localization of diaphragmatic and serratus muscle anterior hydatidosis that occurred simultaneously. CASE REPORT: A 37-year-old developmentally disabled woman presented to the Emergency Department (ED) of Harran University with tachycardia, tachypnea, and dyspnea. On pulmonary auscultation, breath sounds were decreased on the right side. A chest X-ray study revealed a radiopaque right hemithorax with a mediastinal shift and tracheal displacement. Thoracic computed tomography scan revealed a hydatid cyst in the serratus muscle anterior and cystic vesicles in the pleural cavity. The patient underwent chest drainage. During drainage, daughter vesicles within the pus were detected macroscopically. An elective thoracotomy was performed after hemodynamic stabilization of the patient. Postoperative chest X-ray study demonstrated that the lungs had re-expanded. The patient had no postoperative complications and was discharged with relief of all symptoms. CONCLUSION: Hydatid cyst should be considered, especially in endemic regions, in the differential diagnosis in the presence of a rare localization or unexpected clinical presentation. Surgical intervention is the appropriate approach for the treatment of hydatid cyst when there is concomitant intrathoracic involvement.

An incidental solitary fibrous tumour in the retroperitoneum, coexisting with ipsilateral atrophic kidney.

Solitary fibrous tumour (SFT) is a relatively uncommon spindle-cell neoplasm that most commonly arises in the pleura, but which may also arise from other serosal surfaces outside the pleura. However, SFT is now known to affect various serosal surfaces including pericardium, peritoneum, retroperitoneum nasal and paranasal sinuses, thyroid, cavernous sinus or pituitary fossa. The histologic features of this lesion may create diagnostic confusion with a variety of other spindle-cell tumours. To the best our knowledge, no cases with SFT have been previously noted in the retroperitoneum coexisting with atrophic kidney. Herein, we report the unique association of a solitary fibrous tumour in the retroperitoneum coexisting with ipsilateral atrophic kidney in a 60-year-old man and define histopatological findings of this tumour.

Effects of Nigella sativa and albendazole alone and in combination in Toxocara canis infected mice.

OBJECTIVE: Nigella sativa extract has been used in the Middle East as a traditional medicine for several complaints. We aimed to evaluate the biochemical, histopathological and hematologic changes in Toxocara canis-infected mice after treatment with Nigella sativa extract, albendazole or a combination of both. METHODS: This comparative study was conducted between June and July 2008 at the Itarran University Saniturla Turkey. Sixty healthy adult BALB/c male mice were randomly divided into six groups (D0-D5). Mice in groups D1-D5 received 500 embryonated T. canis eggs via esophageal tube. Groups DO and D1 served as a non-infected sham group and an infected control group, respectively. Groups D2 and D3 received 100 and 200 mg/kg N. sativa extract (NSE), respectively. Group D4 received 100 mg/kg albendazole. Group D5 received the combination dose (100+100 mg/kg NSE+albendazole). RESULTS: Treatment with N. sativa of both doses or the combination dose of N. sativa and albendazole reduced the degree of inflammation and necrosis, lead to a reduction in the percentage of eosinophils and decreased the elevated liver enzyme levels. CONCLUSION: These results indicate that N. sativa has a potent effect in protection against organ damage induced by T. canis infection.

A new seton tightening method for anal fistula treatment: sailor's knot.

AIM: There are certain problems experienced while retightening the seton material during the patient follow-ups, such as pain and anaesthesia requirements in perianal fistula. The aim of the present study was to compare a sailor's knot with other seton tightening methods for the surgical treatment of perianal fistulas. MATERIAL AND METHODS: The records of 105 patients who underwent surgeries for perianal fistulas using the seton method between 2016 and 2019 were analysed retrospectively. The demographic characteristics, complaints, fistula localizations, surgery types, hospital stay lengths, postoperative complications and imaging modalities of the patients included in the study were recorded. The patients were divided into two groups according to the surgical treatment method. Those patients who underwent seton procedures with a sailor's knot were included in Group 1. Group 2 included those patients who underwent other seton procedures, including silk and penrose drain procedures. Groups were compared with regard to success rates and postoperative recurrence. RESULTS: There was no statistically significant difference between the groups in terms of the age, gender, fistula type and follow-up duration. Success rate in all patient was 88.6%, 91.2% in group 1 and 87.1% in group 2 (p=0.36). The number of patients with a kind of incontinence was 7 (7.1%), 3 (5.8%) in Group 1 and 4 (7.4%) in Group 2 (p = 0.297). CONCLUSION: There were no statistically significant differences with regard to complications and recurrences between the sailor's knot and the other seton tightening methods used for the treatment of anal fistulas. The sailor's knot is recommended with regard to its easy application and seton retightening with satisfactory outcomes. KEY WORDS: Perianal fistula, Sailor's knot, Seton.

Pneumoperitoneum, pneumoretroperitoneum and bilateral pneumothorax caused by ERCP.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the mainstay procedure treatment of hepatobiliary and pancreatic diseases. Life-threatening complications such as pneumoperitoneum, pneumoretroperitoneum, pneumomediastinum, subcutaneous emphysema and pneumothorax related to this procedure rarely occur and only a few cases are reported in English literature. Herein, we report a patient who developed acute abdominal symptoms with subcutaneous emphysema and bilateral pneumothorax due to duodenal perforation, accompaniment of ERCP that was successfuly treated.

[Post-operative bacteremia caused by multidrug-resistant Aerococcus viridans in a patient with gall bladder cancer]. / Safra kesesi kanseri olan bir hastada operasyon sonrasi gelisen cok ilaca dirençli Aerococcus viridans bakteriyemisi.

Aerococcus viridans is a gram-positive, catalase and oxidase negative, microaerophylic and non-motile coccus which is rarely associated with human infections such as endocarditis, meningitis, artritis and bacteremia. We report a case of bacteremia due to A. viridans in a 61-years-old man with malignant gall bladder neoplasm. The patient underwent a surgical operation and on the 5th day of operation he had severe abdominal pain, vomiting, high fever and discharge from operation site. He was transferred to intensive care unit and blood cultures were obtained. Piperacillin-tazobactam was initiated as empirical therapy. Blood cultures performed in Bactec system (Becton Dickinson, USA) yielded catalase negative, gram-positive cocci in tetrads. The isolate was pyrrolidonyl aminopeptidase (PYR) positive and produced alfa-hemolysis on sheep blood agar. These cocci were identified as A. viridans by Vitek 2 Compact System (BioMerieux, France) and identification was confirmed by using mini API System (BioMerieux, France). Antibiotic susceptibility testing performed with Kirby-Bauer disk diffusion method revealed that the isolate was susceptible to trimethoprim-sulfamethoxazole, tigecycline and vancomycin and resistant to penicillin, ampicillin, piperacillin-tazobactam, ceftriaxone, erythromycin, clindamycin and amikacin. The patient was successfully treated with vancomycin (2 x 1 g/day) and completely recovered without complication. In conclusion, A. viridans should be suspected as an opportunistic pathogen in immunocompromised patients and these patients should be treated according to the antibiotic susceptibility test results.

The clinical characteristics and surgical approach of scar endometriosis: A case series of 14 women.

Scar endometriosis, also referred to as abdominal wall endometriosis (AWE), is a rare form of endometriosis that usually develops in the scar after obstetric or gynecological surgeries, including cesarean section (CS). Recently, the occurrence of scar endometriosis has been increasing together with the increase of CS incidence. Scar endometriosis can be clinically misdiagnosed as hernia, lipoma, or hematoma. Here we retrospectively analyzed the clinical aspects of scar endometriosis and surgical approach in 14 patients from a tertiary hospital, who were treated by surgery, between 2012 and 2017. The mean age was 32.71 ± 8.61 years (range: 19-45). Palpable mass and cyclic pain at the scar site were the most common complaints. Twelve patients had previously undergone CS, and two patients had undergone a surgery of ovarian endometrioma. The preoperative diagnosis was determined with ultrasonography (US), magnetic resonance imaging (MRI), or computed tomography (CT). Preoperatively, scar endometriosis was diagnosed in 12/14 patients (85.7%), while 2 patients (14.3%) were diagnosed with inguinal hernia. The treatment was surgical excision in all patients; in addition, mesh repair surgery was performed in 1 patient with recurrent scar endometriosis. Postoperatively, endometriosis was confirmed by histology in all patients. The average size of endometriomas was 24.71 ± 6.67 mm (range: 11-35). No woman had concurrent pelvic endometriosis. In the follow-up period (mean: 9 months) the recurrence of endometriosis was not observed. Scar endometriosis should be considered in all women of reproductive age presenting with cyclic pain and swelling in their abdominal incision sites.

Investigation of IVS14+ 1G > A polymorphism of DPYD gene in a group of Turkish patients with colorectal cancer.

BACKGROUND: Dihydropyrimidine dehydrogenase (DPD) is a critical enzyme in the catabolism of 5-fluorouracil (5-FU), a drug frequently used in cancer therapy. One of the possible causes of severe 5-FU toxicity is genetic polymorphisms in the DPYD gene, such as IVS14+1G > A. In this study we aimed to investigate the frequency of the IVS14+1G > A mutation in the DPYD gene in Turkish patients with colorectal cancer (CRC) and healthy controls. MATERIALS AND METHODS: Blood samples were collected from 218 individuals (56 patients with CRC and 162 healthy individuals), and the DNA was isolated. A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to detect the frequency of the IVS14+1G > A mutation in our population. RESULTS: The IVS14+1G > A mutation (heterozygous) in the DPYD gene was identified in two healthy subjects in this Turkish population. CONCLUSION: The apparently high prevalence (allele frequency of 0.6%) of the IVS14+1G > A mutation warrants genetic screening for this mutation in cancer patients before the administration of 5-FU.

The effects of isothermic or hypothermic carbon dioxide pneumoperitoneum on arterial blood gases.

OBJECTIVE: To investigate the effects of isothermic or hypothermic carbon dioxide used for pneumoperitoneum during laparoscopic cholecystectomy on blood gases. METHODS: Between 2004 and 2006, 62 patients (American Society of Anesthesiologists grade I, II, and III for elective laparoscopic cholecystectomy) (age between 18 and 70 years), were enrolled in this prospective randomized study. The patients were divided into 2 groups. In the isothermic group, 37 degrees C carbon dioxide was used, and 21 degrees C carbon dioxide was used in hypothermic group. Core body temperature at esophagus and skin temperature were measured at 10-minute intervals beginning just before insufflation and during pneumoperitoneum. Blood arterial pH, arterial carbon dioxide pressure, arterial oxygen pressure, and bicarbonate values were measured just before insufflation, at 30 minutes of pneumoperitoneum, and 30 minutes after desufflation. RESULTS: The mean skin body temperature was significantly higher in the isothermic group than the hypothermic group, no significant difference was observed in core body temperature and blood arterial pH, arterial carbon dioxide pressure, arterial oxygen pressure, and bicarbonate values. CONCLUSION: Warming insufflated carbon dioxide in laparoscopy does not affect blood gases.

Can ultrasonic surgical devices be used to close the appendicular stump?

Laparoscopic appendectomy is increasingly being performed because of its quick recovery time, low instance of wound infection, and early return of patients to home and work. Operating time should be short yet safe. Therefore, in this study, we compared the effects of various sealing systems on the length of surgery and examined whether these systems could be used to separate the appendix from its stump successfully. This prospective and randomized ex vivo study was conducted on 20 consecutive patients diagnosed with acute appendicitis. All patients underwent classical open appendectomy. The patients were classified into two groups according to the type of sealing system used. The LigaSure® system was used for coagulation in Group L and the Harmonic® system in Group H. After coagulation, a pressure system was used to evaluate the closure of the appendix. Results showed that the use of ultrasonic instruments alone to close the appendiceal stump caused an incomplete closure. KEY WORDS: Appendicular stump, Laparoscopic appendectomy.

Incidental gallbladder cancer at cholecystectomy.

BACKGROUND: Gallbladder tumours rank fifth in the world among gastrointestinal system tumours. Coincidental gallbladder tumours are diagnosed during cholecystectomies, or by examining the cholecystectomy material. AIMS: In this study, we aimed to evaluate the incidence of gallbladder cancer among patients undergoing cholecystectomies due to gallbladder disease. STUDY DESIGN: Retrospective study METHODS: The files of 341 patients who had undergone routine cholecystectomy operations between January 2013 and March 2016 were reviewed, and their pathology results were recorded. Those patients with gallbladder carcinomas were evaluated in terms of age, gender, preoperative findings, existing symptoms, radiological findings, surgical findings and follow-up. The cancer invasion depth was classified according to the American Joint Commission on Cancer (AJCC) atlas, and this study was approved by the ethical committee of our university. RESULTS: Among the 341 patients who participated in this study, 253 (74.41%) were female, 88 (25.80%) were male, and their average age was 49.61 years old (17-86). Seven of the patients (2.05%) had gallbladder tumours; six of which were female, one was male and their average age was 67.71 years old (62-76). One tumour was diagnosed as a frozen specimen during the operation, while the others were diagnosed during the postoperation phase. Three of the patients had T1b and four had T2 tumours. CONCLUSION: Gallbladder tumours detected incidentally could extend survival rates with proper surgical intervention and chemotherapy. The possibility of a tumour should not be dismissed in those patients with advanced age, females or patients with gallbladder stones. Frozen specimens should be created during a cholecystectomy, and if there is any doubt about the diagnosis, a postoperative histopathological examination of the gallbladder should be conducted. KEY WORDS: Cholecystectomy, Gall bladder stone, Incidental gallbladder carcinoma.

The effects of lycopene on intestinal injury due to methotrexate in rats.

OBJECTIVE: The aim of this study was to investigate the effects of lycopene (Lyc) on methotrexate (Mtx)-induced intestinal damage in rats. METHOD: Twenty-eight male Sprague Dawley rats were divided into four equal groups: control, Mtx, Lyc, and Mtx-L. CONTROL GROUP: Rats were given only the vehicle. Lyc group: Rats were given Lyc (10 mg/kg) with corn oil by oral gavage for 10 days. Mtx group: Rats were injected intraperitoneally with a single dose of 20 mg/kg of Mtx and given corn oil by oral gavage. Mtx-L group: Rats were treated with Lyc (10 mg/kg) for 10 days after a single dose of Mtx (20 mg/kg). All of the rats were euthanized using terminal anesthesia, and the intestinal tissues were removed for histological examination and for pro-inflammatory cytokine measurement (tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1ß)), total oxidative status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI). RESULTS: Mtx administration increased histopathological damage and increased TNF-α, IL-1ß, TOS, TAC, and OSI levels in the small intestine tissues. Lyc therapy applied to the Mtx-L group provided significant improvement in all parameters of histopathological damage to the small intestine and significantly reduced the levels of IL-1ß, TOS, and OSI in the intestinal tissues. CONCLUSIONS: The results of this study indicate that Lyc might be useful for protecting intestinal damage induced by Mtx in rats by reducing the increased oxidative stress and pro-inflammatory cytokine (IL-1ß) levels.

Minimal effective dose of povidone-iodine in abdominal surgery Our clinical experience.

UNLABELLED: The aim of this study is to evaluate the thyroid function tests in order to examine whether 10 % of Povidone-Iodine(PI), the medication we applied in 1/5 ratio diluted with 0.9 %NaCl, joins the systemic circulation during clean contaminated, contaminated and dirty operations for solid organ hydatid cysts in abdominal area to avoid abscess formation and spreading. 7 men and 6 women were included to the present study, prospectively. The mean age was 33.69(± 13.49). TSH, free T3 (fT3) and free T4 (fT4) hormone levels were measured before the operation and at the third day of postoperative period. Amount of used povidone-iodine for patients was recorded. As a result of statistical analysis applied, the preoperative and post operative values were not significantly different regarding with the measured hormone levels (preTSH vs postTSH: p= 0.984; prefT3 vs postfT3: p= 0.101; prefT4 vs postfT4: p=0.146). Thus, it has been shown that the dose we used is effective, and it does not enters at all or at quite low levels into the systemic circulation. Patients whom this application performed, abscess and intestinal adhesions have not been observed in our clinical experience. We recommend the use of suggested doses of Povidone-Iodine in the presence of intraabdominal perforation and abscess or in cases such as carrying a risk of cyst spreading to intraabdominal area in hydatid cysts. KEY WORDS: Povidone-iodine, Surgical adhesions, Surgical wound infections, Thyroid function tests.

Surgical treatment of hepatic hydatid cysts A retrospective analysis of 425 patients.

BACKGROUND: We aimed to retrospectively analyze patients who underwent surgical treatment in our clinic for hydatid cysts in terms of the surgical methods implemented and their results. METHODS: Archival records of the patients who underwent surgery for the treatment of hydatid cysts between 2007 and 2014 were analyzed retrospectively. RESULTS: The records of 425 patients who underwent surgery with varying ages of 16 to 88 years (mean: 44.5) were obtained. Among the patients, 33.9% (n=144) were male and 66.1% (n=281) were female. The most frequent symptoms were abdominal pain (46.4%) and dyspepsia (30.9%). About 79.5% of the patients had hydatid cysts in their livers, and 66.8% of these cysts were on the right lobe of the liver. Surgical intervention was performed on 513 cysts. The average diameter of these cysts was 8.3 cm. About 85.5% (n= 438) of the interventions implemented were partial cystectomy. Laparotomy was performed through the right subcostal incision on 81% (n=345) of the patients who underwent conventional surgery. The most frequently encountered complication was biliary fistula. The mortality rate was 0%. CONCLUSIONS: The results showed that most of the cases were uncomplicated isolated hepatic hydatid cysts frequently found on the right lobe of the liver. The most frequently implemented surgical procedure was partial cystectomy. This procedure was simple, fast and applicable for uncomplicated hepatic hydatid cysts. KEY WORDS: Hepatic hydatid cyst, Mortality, Partial cystectomy.

Hemostatic efficacy of a traditional medicinal plant extract (Ankaferd Blood Stopper) in bleeding control.

The aim of this study is to assess the in vivo hemostatic effect of Ankaferd Blood Stopper (ABS) on rats using a tail bleeding model. Wistar rats were randomized into 4 groups of 9 each: group 1, control, no pretreatment, irrigated with saline; group 2, no pretreatment, irrigated with ABS; group 3, control, heparin pretreatment, irrigated with saline; and group 4, heparin pretreatment, irrigated with ABS. To control bleeding, compressive dressings were placed after instilling 1 mL of either ABS or saline to the bleeding area. Without heparin pretreatment, ABS shortened hemostasis time by 1.57 minutes and reduced the amount of bleeding by 0.85 g. With heparin pretreatment, ABS shortened hemostasis time by 3.29 minutes and reduced the amount of bleeding by 1.32 g. The ABS was more effective than saline irrigation for treating tail tip bleeding in rats, with or without heparin pretreatment, while also using a compressive dressing.

Efficacy of diffusion-weighted magnetic resonance imaging in follow-up patients treated with open partial cystectomy of liver hydatid cysts.

BACKGROUND AND OBJECTIVE: The aim of this study was to evaluate the efficacy of DWI in differentiation of patients with residual cavity and type 1 hydatid cyst (HC) in the liver. METHODS: 32 patients were included. 12 of these patients had type 1 HC and the remainders (n = 20) had postoperative residual cavities. In all patients, axial T2-weighted and DWI images were obtained. An apparent diffusion coefficient (ADC) map of the images was automatically generated and the ADC values were measured on this map for all patients. Mann-Whitney U test was used for comparison of continuous variables between two groups. RESULTS: The mean diameters of type 1 hydatid cyst and residual cavity groups were 83.42 mm, 49.30 mm, respectively (P = 0.001). There were no significant differences in gender and age between the groups (both P > 0.05). The mean ADC values of type 1 hydatid cyst and residual cavity groups were 2.58 ± 0.13 × 10(-3) s/mm(2), 2.58 ± 0.16 × 10(-3) s/mm(2), respectively (P = 0.953). CONCLUSION: DWI might not be suitable to differentiate the postoperative residual cavity from the type 1 hydatid cyst in the liver due to similarity of ADC values between postoperative residual cavity and type 1 hydatid cyst.
