AbstractAfter surgery, the most common foreign bodies retained in the abdominal cavity are the surgical sponges. The aim of the present study was to emphasize the importance of gossypiboma, which is a serious and medicolegal problem. The records of 12 patients with a confirmed diagnosis of gossypiboma after abdominal surgery at Dicle University Hospital were retrospectively reviewed between January 1994 and December 2009. Eight of the 12 patients were females, and 4 were males. Previously, 7 patients had been operated on electively, and 5 had undergone operations on an emergency basis. Abdominal ultrasonography clearly demonstrated gossypibomas in 5 patients, and computed tomography demonstrated a more precise image of retained surgical sponges in 3 patients. One patient died because of ventricular fibrillation; the other 11 patients were discharged in good health. To eliminate the risk of gossypibomas, all sponges should be counted at least twice (once preoperatively and once postoperatively); use of small sponges should be avoided during laparotomy, and only sponges with radiopaque markers should be used. The surgeon should explore the abdomen before closure. In cases in which the sponge count is uncertain, an abdominal x-ray should be performed before closure.

Duplication cysts are rare gastrointestinal congenital abnormalities and can occur anywhere within the gastrointestinal tract. Duplication cysts are firmly attached to or share the wall of the alimentary tract and have a common blood supply with the adjacent segment of the bowel. Completely isolated duplication cysts are an extremely rare variety of gastrointestinal duplications with their own exclusive blood supply, and they do not communicate with the intestine. These cysts are usually diagnosed during early childhood, and very rarely detected in adults, mostly incidentally, due to a lack of symptoms. A 28-year-old male was admitted to our hospital with a chief complaint of lower abdominal pain and distention and a palpable mass for 1 month. Based upon computed tomography and sonographic findings, a small bowel duplication cyst was tentatively diagnosed. The cyst had no connection to the gastrointestinal tract. Herein we report the case of a noncommunicating isolated ileal duplication cyst in an adult. Resection of the cyst was performed safely without requiring bowel resection.

Background: The aim of this study was to investigate the possible protective role of antioxidant treatment with ellagic acid (EA) on lung injury after intestinal ischemia-reperfusion (I/R) injury using biochemical and histopatological approaches. Materials and Methods: Forty rats were divided into four groups as control, control + EA, I/R, and I/R + EA. The control and control + EA groups were also anesthetized and subjected to laparotomy, but without clamp application. The control + EA and I/R + EA groups were given EA (85 mg/kg) orally prior to experiment. The I/R and I/R + EA groups underwent 30 minutes of intestinal ischemia and 1 hour of reperfusion. In all groups, serum total antioxidant capacity (TAC) and malondialdehyde (MDA) levels were determined. TAC, total oxidative status (TOS), and oxidative stress index (OSI) in lung tissue were measured. Lung tissue histopathology was also evaluated by light microscopy. Results: TAC levels were higher in control, EA, and I/R + EA groups while TOS, OSI, and MDA levels were lower in these groups compared with I/R group. Serum MDA levels were significantly higher in I/R + EA group than that of control group. Lung tissue TAC levels were lower in I/R + EA group while OSI values were higher in that groups compared with EA group. Histological tissue damage was milder in the EA treatment group than in the I/R group. Conclusion: These results suggest that EA treatment protected the rats lung tissue against intestinal I/R injury.

BACKGROUND A wandering spleen, defined as a spleen without peritoneal attachments, is a rare entity characterized by splenic hypermobility due to laxity or maldevelopment of the supporting splenic ligaments. Patients with a wandering spleen may be asymptomatic, or may present with a palpable mass in the abdomen, or with acute, chronic, or intermittent symptoms due to torsion of the wandering spleen. Because early clinical diagnosis is difficult, imaging modalities play an important role in the diagnosis. Treatment should be planned according to the vitality of the spleen. CASE REPORT A 22-year-old woman presented with an acute abdomen that was found to be due to a wandering spleen with 720° anti-clockwise torsion around the pedicle. CONCLUSIONS Splenectomy is advocated in the presence of torsion, splenic vein thrombosis, or splenic infarction. Conversely, when a viable wandering spleen is found at laparotomy, detorsion with splenopexy is preferred.

Background: Blue dye used for sentinel lymph node biopsy (SLNB) in breast cancer patients may cause prolonged skin discoloration at the site of injection. The aim of this study was to assess the duration of such skin discoloration. Patients and Methods: 236 consecutive patients who had undergone breast conserving surgery and SLNB for breast cancer were reviewed prospectively from January 2007 to December 2009. Results: Of the 236 patients, 2 had undergone bilateral surgery, and 41 had been examined in consecutive yearly reviews. Blue discoloration remained visible at the injection site after 12, 24, and > 36 months in 36.5, 23.6, and 8.6% of the patients, respectively. Conclusion: The use of patent blue for identification of the sentinel lymph node in patients undergoing breast cancer surgery may result in prolonged discoloration of the skin at the injection site.

OBJECTIVES The present study aimed to present the clinical and multidetector computed tomography (MDCT) findings of patients who were diagnosed with the median arcuate ligament (MAL) syndrome on MDCT retrospectively. METHODS Seven hundred forty-four patients in whom MDCT angiography was performed were retrospectively analyzed for investigating incidental MAL syndrome. RESULTS Twenty-one patients were shown to have MAL syndrome. Of 21 patients, 18 with MAL syndrome were asymptomatic. Three patients had some symptoms. On MDCT angiography, proximal narrowing of the arteries was observed in 21 patients. CONCLUSIONS MDCT is a minimally invasive and useful tool for the diagnosis of MAL syndrome.

PURPOSE The purpose of this study was to identify the factors that may have an impact on upgrading atypical ductal hyperplasia (ADH) lesions to malignancy. MATERIALS AND METHODS Between February 1999 and December 2010, the records of 150 ADH lesions that had been biopsied were retrospectively reviewed. The biopsy types included 11-gauge stereotactic vacuum-assisted biopsy (SVAB) (n=102) and ultrasonography (US)-guided 14-gauge automated biopsy (n=48). The patients were divided into two groups: those who had cancer in the final pathology and those who did not. Variables associated with underestimation of ADH lesions were compared between the groups. RESULTS The underestimation rates according to the biopsy types were 41.7% (20/48) for the US-guided 14-gauge automated biopsy and 20.6% (21/102) for the 11-gauge SVAB (P = 0.007). The rate of underestimation was significantly higher in lesions greater than 7 mm than it was in smaller lesions, with both US-guided 14-gauge automated biopsy and 11-gauge SVAB (P = 0.024 and P = 0.042, respectively). The rate of underestimation was significantly higher with the 11-gauge SVAB (P = 0.025) in lesions that were suspicious (R4) and highly suggestive of malignancy (R5) than in those that were probably benign (R3). CONCLUSION The underestimation rate in ADH lesions was significantly higher with US-guided 14-gauge automated biopsy compared to the 11-gauge SVAB. The underestimation rate was also significantly higher in lesions greater than 7 mm regardless of the biopsy type, and in lesions biopsied using SVAB that were regarded as suspicious (R4) or highly suggestive of malignancy (R5) on imaging.

We aimed to present our clinical experience with FG treatment. Fourniers gangrene (FG) is a rare but serious disease characterized by progressive necrosis in the genitourinary and perineal region. The retrospective study included 43 patients. Patients were divided into 2 groups as survivors and nonsurvivors. Included in the analysis were data pertaining to demographics, predisposing factors, comorbidities, results of bacteriologic analyses, number of debridements, duration of treatment, FG Severity Index (FGSI) score, fecal diversion methods (trephine ostomy or Flexi-Seal Fecal Management System-FMS), and dressing methods (wet or negative aspiration system). In the nonsurvivor group, urea, WBC, and age were significantly higher, whereas albumin, hematocrit, platelet count, and length of hospital stay (LOHS) were significantly lower compared to the survivor group. Mean FGSI was lower in survivors in comparison with nonsurvivors (5.00 ± 1.86 and 10.00 ± 1.27, respectively; P < 0.001). We conclude that FGSI is an important predictor in the prognosis of FG. Vacuum-assisted closure (VAC) should be performed in compliant patients in order to enhance patient comfort by reducing pain and the number of dressings. Fecal diversion should be performed as needed, preferably by using FMS. The trephine ostomy should be the method of choice in cases where an ostomy is necessary.

PurposeRectal injuries, which are rarely encountered because of the anatomic characteristics, occur due to penetrating traumas. In the current study, we aimed to present experiences gleaned from our clinic concerning rarely encountered unusual rectal injuries, including those cases presented for the first time.MethodsEleven patients who had been treated for unusual rectal injuries in the General Surgery Clinic of Dicle University between 2004 and 2011 were retrospectively reviewed.ResultsThe reasons for rectal injuries included foreign bodies in four cases, sexual intercourse in three cases, iatrogenic injuries in two cases, electric shock in one case, and animal horns in one case. All cases had extraperitoneal rectal injuries and all injuries were grade 2 injuries, except for the electrical burn. Primary repair was adequate for the treatment of six patients. Four patients underwent primary repair and ostomy, whereas one of the patients underwent debridement and an ostomy. The patients recovered without complications, except for one patient with sphincter insufficiency.ConclusionThe results of the current study suggested that primary repair is adequate in the patients with low-energy injuries and early presentation, whereas an ostomy is required for those with late presentation and for those with high-energy and destructive injuries.

PURPOSE The aim of this study was to determine the causes and rate of failure in removing calcification in microcalcification-only lesions using 11-gauge stereotactic vacuum-assisted breast biopsy. MATERIALS AND METHODS In total, 1365 microcalcification-only lesions were included in this study. The breast biopsy database was reviewed retrospectively. The biopsies were divided into two groups based on whether the specimen X-ray showed calcium within the cores. Breast composition, lesion size, calcification distribution, density on mammography, and the number of specimens were compared between the two groups. RESULTS In 11 (0.8%) biopsies, no calcium in the specimen radiography could be identified. Re-biopsy was performed in five cases. The initial biopsy result was unchanged at the second biopsy in three cases containing calcium, while in the other two cases, a benign biopsy result was upgraded to atypical ductal hyperplasia and ductal carcinoma in situ, respectively. In six cases, the biopsy was not repeated despite the absence of calcium in the specimen X-ray. In three of these cases, calcifications were reported histopathologically and deemed to be too small to be identified on specimen X-ray. In two of six patients, sufficient information was found in the cores without microcalcification to indicate the need for surgery. One patient refused re-biopsy. A statistically significant higher failure rate was observed in low-density calcification compared with intermediate or high-density calcification on mammography. CONCLUSION The failure to retrieve microcalcification is uncommon when an 11-gauge vacuum-assisted breast biopsy is used. Low-density calcifications have a higher rate of failure. In cases in which no calcium is observed in specimen radiography, repeated biopsy is recommended.
