Intramural hematoma of the intestine is a rare complication of anticoagulant therapy. We evaluated 7 nontrauma patients with intramural hematoma of the intestine diagnosed at our institution between May 1998 and June 2001. All of the patients were receiving long-term anticoagulant therapy for previous diseases. All 7 patients had abdominal pain, 6 had additional symptoms of nausea and vomiting, and 4 had melanotic stools at admission. Six of the patients had abnormal coagulation parameters. Both abdominal ultrasonography (US) and computerized tomography (CT) showed the exact pathology in all patients. Five of the 7 patients were treated, nonoperatively, and the other patients underwent surgery. All of the patients were followed with abdominal US and CT (mean 12 = months), with complete resolution of their intramural hematomas. Abdominal US and CT evaluation performed together will help the accuracy of diagnosis of intramural hematoma, but nonoperative therapy is the treatment of choice, with surgery indicated if generalized peritonitis or intestinal obstruction develops.

Abstract: Seroma formation is a frequently occurring complication in patients operated on because of breast cancer. This complication can be the cause of flap necrosis, can lead to infection, and can prolong the hospital stay. It can also cause a delay in chemotherapy and radiotherapy. In order to prevent seroma formation, various methods such as external compression dressings, immobilization of the arm, sclerotherapy, and suction drainage have been used, without much success. In animal models and some clinical studies, it has been stated that fibrin glue reduces seroma formation, and these statements generated high expectations. For this reason, a prospective study was planned to test this in patients who underwent modified radical mastectomy (MRM) because of breast cancer. Of the 54 patients studied, 27 patients had fibrin glue (4 ml) applied to wound surfaces and under the flap (study group); the remaining 27 patients were the control group. Daily drainage volumes, total amount of drainage, drain removal time, and seroma formation were recorded and compared between the two groups. The first‐day drainage was significantly lower in the study group (p < 0.05, Students t‐test). There were no significant differences in daily drainage volumes, drain removal time, seroma formation frequency, and the number of seromas between the two groups (p > 0.05). In conclusion; fibrin glue application had no significant benefit on axillary lymphatic drainage, drain removal time, or seroma formation.

Background: Percutaneous drainage with alcohol injection for hydatid cysts has been commonly used in the last two decades. Albendazole is the drug of choice in the medical treatment of hydatidosis, and has also been used as an intraoperative scolicidal solution. The side‐effects of its local application are not well known and have not been investigated. The purpose of the present study was to investigate the effects of the intracystic injections of alcohol and albendazole solutions on the hydatid cysts and hepatobiliary system of rabbits.

Background: Hepatic hydatidosis still remains as a serious problem in general surgery. Recurrence and/or secondary hydatidosis rates are up to 25% in the cases treated with surgery alone. Albendazole is the most commonly used drug in the medical treatment of echinococcosis. The aim of the present study was to evaluate the effect of albendazole using the intraoperative and perioperative periods as dual therapy.

Objective: The aim of this study was to investigate gallbladder motility in children with Down syndrome by measuring gall-bladder volume and contraction index. Methods: This study, performed between January 2001 and December 2002 at the Ondokuz Mayis University, School of Medicine, Department of Paediatric Neurology, Samsun, Turkey, included 21 patients with Down syndrome (study group) and 22 healthy children (control group). After an 8-hour fast, gallbladder diameters in both groups were measured in length, width, and height by ultrasonography before and 30 minutes after a test meal. The volume of gallbladder before and after a test meal was determined, and the contraction index was calculated. Blood triglyceride and cholesterol levels were measured, and 5-hydroxyindoleacetic acid (5-HIAA) levels in urine were determined. Results: Mean gallbladder volume before test meal in the study group and controls was 8,412.4 ± 5,174 mm3 and 16,516.8 ± 6,796.1 mm3 (P < 0.001), respectively. The mean contraction index of the study group was 41.2% ± 19.4% and of controls, 75.0% ± 12.3% (P < 0.001). The mean triglyceride level of the study group was significantly higher than controls (P < 0.05). The mean urine 5-HIAA level of the study group was lower than controls (P < 0.05). Conclusion: CI was lower in patients with Down syndrome, suggesting gallbladder hypomotility. Hypomotility may be a feature associated with the high prevalence of gallstones in Down syndrome.

Objective: To examine the effect of silymarin (SM), a mixture of flavonoids and polyphenols extracted from Silybum marianum, on mesenteric ischemia-reperfusion (I-R) injury in a rat model. Materials and Methods: Fifty rats were randomly divided into 5 groups (n = 10). Group 1 was sham operated, while groups 2-5 were subjected to mesenteric I-R lasting 1 h. Group 2 received isotonic sodium chloride, group 3 received SM (100 mg/kg/day) for 7 days before I-R, group 4 received SM for 7 days after I-R, and group 5 received SM for 7 days both before and after I-R. The rats were sacrificed by exsanguination in groups 1-3 at the 24th hour and groups 4 and 5 were sacrificed on the 7th day of reperfusion. Blood and intestinal specimens were taken for biochemical and pathological evaluations. Results: Serum superoxide dismutase (SOD) and heat shock protein 70 levels were significantly higher in group 2 (5.24 ± 1.76 U/l and 261.4 ± 16.8 ng/ml) compared to the sham group (2.08 ± 1.76 U/l and 189.9 ± 28.7 ng/ml) (p < 0.001 and p < 0.0001, respectively). However, SOD activity and the extent and severity of the histopathological lesions were significantly less in groups 3 [3.11 ± 1.18 U/l, 1.0 (range 0.0-2.0)], 4 [2.15 ± 0.87 U/l, 1.0 (range 1.0-3.0)], and 5 [1.80 ± 0.61 U/l, 0.5 (range 0.0-2.0)], treated with SM, than in group 2 [5.24 ± 1.76 U/l, 2.0 (range 2.0-3.0)] (p = 0.002, p < 0.001, and p = 0.0001; p < 0.001, p = 0.007, and p = 0.0001, respectively). Also, TNF-α levels were lower in the SM-supplemented groups compared to group 2. Serum thiobarbituric acid-reactive substance concentrations were low in the pre-/posttreatment groups treated with SM compared to group 2. No statistical difference was observed for protein carbonyls between the groups. Conclusion: Our findings suggest that SM therapy may attenuate the oxidative and intestinal damage induced by I-R injuries.

Principles. Coumadin-induced renal and retroperitoneal hemorrhages are rare. Clinical and laboratory findings are not specific for the diagnosis. Computed tomography (CT) has some advantages in the evaluation of these patients. The aim of this study is to report our experience regarding renal and retroperitoneal hemorrhage due to Coumadin, and describe clinical and CT findings, treatment, and prognosis of the patients. Methods. We reviewed our CT archive to search patients with renal and retroperitoneal hemorrhage caused by Coumadin treatment retrospectively. A total of seven patients with Coumadin-induced renal and retroperitoneal hemorrhages were included in this study. Results. Four patients had abdominal pain, two patients had hematuria, and one patient had abdominal pain and hematuria. There was retroperitoneal hemorrhage in three patients on abdominal CT. One patient had hemorrhage in the renal pelvis and the jejunum, another had hemorrhage in the renal pelvis and the perirenal area, and another had hemorrhage in the perirenal area and the retroperitoneal region. In the last patient with hematuria, there was no hemorrhage. None of the patients had a lesion-causing hemorrhage. Coumadin was stopped, and vitamin K and fresh-frozen plasma were given to patient. One patient with massive retroperitoneal hemorrhage died, whereas other patients were successfully treated using conservative approaches. Conclusions. Hematuria and abdominal pain are the most common complaints in Coumadin-induced renal and retroperitoneal hemorrhage. CT can be the first imaging modality in these patients due to its ability to directly evaluate all peritoneal and retroperitoneal structures. It also allows evaluation of any underlying lesion that can cause hemorrhage from the renal area and the urinary tract. Conservative treatment is the first choice, and prognosis is good when diagnosed early.

BACKGROUND Flap techniques are acceptable for the surgical treatment of pilonidal sinuses. This study assessed a new modification of the rhomboid flap technique. METHODS The study included 133 patients with pilonidal disease who were treated between April 2004 and April 2009. The pilonidal sinus was removed with an oval excision, and an oval head rhomboid flap was prepared to reduce flap necrosis. RESULTS The mean age of the patients was 27.4 ± 4.6 years (range, 13-80). The rate of minor postoperative complications was 11.3%. The mean hospital stay was 2.3 ± .8 days (range, 1-6). The rate of recurrence was 1.5%. Regarding cosmetic results, 116 (87%) patients were very pleased, 15 (11.2%) were pleased, and 5 (3%) were displeased. The mean follow-up period was 22.5 ± 12.4 months (range, 5-57). CONCLUSIONS The oval flap reconstruction method is a recommended procedure that produces fewer ischemic flaps with a low rate of recurrence and acceptable cosmesis.

Background and Aim. There are no accurate methods of differentiating acute biliary pancreatitis. Obstructions of biliary ducts, idiopathic pancreatitis may be related with biliary origin which needs identification for acute treatment. We searched for the predictivity of biochemical markers in early acute biliary pancreatitis. Patients and Methods. Serum levels of AST (Aspartate Transaminase),ALT (Alanine Transaminase), ALP (Alkaline Phosphatase), GGT (Gamma Glutamyl Transferase), total bilirubin, direct bilirubin, LDH (Lactate Dehydrogenase), amylase, lipase, CRP (C-Reactive Protein) and WBC (White Blood Cell) were measured in 157 patients with acute pancreatitis. Biliary and nonbiliary pancreatitis were differentiated by Magnetic Resonance Cholangiopancreatography (MRCP), Endoscopic Retrograde Cholangiopancreatography (ERCP), Intraoperative Cholangiopancreatography (IOC). Cut-off points of admission biochemical markers with sensitivity, specifity, positive predictive value and negative predictive value were determined after identification of significant variables. Receiver Operator Curves were plotted for each biochemical marker. Results. Serum Alkaline Phosphatase, total bilirubin, direct bilirubin, amylase and lipase levels were significantly higher in biliary pancreatitis with a positive predictive value of 80.8%, 83.9%, 81.6%, 78.8%, 79.7%. Conclusion. Increased Alkaline Phosphatase,total bilirubin, direct bilirubin, amylase and lipase levels may be used in prediction of biliary pancreatitis.
