BackgroundEntrapped anorectal foreign bodies are being encountered more frequently in clinical practice. Although entrapped foreign bodies are most often related to sexual behavior, they can also result from ingestion or sexual assault.MethodsBetween 1999 and 2009, 15 patients with foreign bodies in the rectum were diagnosed and treated, at Izmir Training and Research Hospital, in Izmir. Information regarding the foreign body, clinical presentation, treatment strategies, and outcomes were documented. We retrospectively reviewed the medical records of these unusual patients.ResultsAll patients were males, and their mean age was 48 years (range, 33–68 years). The objects in the rectum of these 15 patients were an impulse body spray can (4 patients), a bottle (4 patients), a dildo (2 patient), an eggplant (1 patient), a brush (1 patient), a tea glass (1 patient), a ball point pen (1 patient) and a wishbone (1 patient, after oral ingestion). Twelve objects were removed transanally by anal dilatation under general anesthesia. Three patients required laparotomy. Routine rectosigmoidoscopic examination was performed after removal. One patient had perforation of the rectosigmoid and 4 had lacerations of the mucosa. None of the patients died.ConclusionsForeign bodies in the rectum should be managed in a well-organized manner. The diagnosis is confirmed by plain abdominal radiographs and rectal examination. Manual extraction without anaesthesia is only possible for very low-lying objects. Patients with high- lying foreign bodies generally require general anaesthesia to achieve complete relaxation of the anal sphincters to facilitate extraction. Open surgery should be reserved only for patients with perforation, peritonitis, or impaction of the foreign body.

Carcinosarcoma of the breast, also known as metaplastic carcinoma, is rare with very few cases reported in the literature. A 46-year old female patient presented with a mass in her left breast. Physical examination, ultrasonography and mammography findings were consistent with malignancy. The mass was totally removed. Histopathological examination revealed carcinosarcoma of the breast. Histologic grade of the tumour was III. Ki67 proliferation index was found 40% positive. Tumour cells were positive for p53 (70% positive), c-erb-B2 (5% positive), pancytokeratin and EMA in carcinomatous areas, and vimentin in sarcomatous areas. There was no metastasis in axillary lymph node and distant metastasis. The patient is receiving chemotherapy and is under follow-up in the 54th month. Along with a review of the literature, we present the information regarding the clinical and histological findings and treatment of the patient who was operated due to breast carcinosarcoma.

OBJECTIVE To investigate the relation between fruit seeds, plants residuals and appendicitis. METHODS Among cases that underwent appendectomy, the appendicitis cases having fruit seeds and undigested plant residuals in their etiology were examined retrospectively. Also, histopathological features, age, sex, and parameters of morbidity and mortality were used. RESULTS Fruit seed was found in one case (0.05%) with presence of pus in appendix lumen, undigested plant residuals in 7 cases (0.35%). It was determined that there were appendix inflammation in 2 of the plant residuals cases, while there were obstruction and lymphoid hyperplasia in the appendix lumen of 5 cases. No mortality was observed. CONCLUSIONS The ratio of acute appendicitis caused by plants is minimal among all appendectomised patients, but avoidence of eating undigested fruit seeds and chewing plants well may help to prevent appendicitis.

CONTEXT Carcinosarcoma of the pancreas is a rare entity comprising a small subset of all pancreatic neoplasms. Diagnosis is usually established by immunohistochemical examination of the resected specimen. Prognosis is limited to several months after resection. CASE REPORT We review the current literature on this rare type of neoplasia, considering histopathological and clinical features. The pathologic findings revealed areas of both adenocarcinoma and sarcoma of the pancreas. The adenocarcinomatous areas localized to the tumor within the head of the pancreas whereas the sarcomatous areas localized to regions of the intraductal component. DISCUSSION Carcinosarcoma of the pancreas is a rare disease having a dismal prognosis. To our knowledge, this carcinosarcoma is the very rare reported case of a primary pancreatic neoplasm with mixed carcinomatous and sarcomatous components.

Purpose Appendectomy applied from the diagnosis of acute appendicitis is one the most common operations in surgery. The rates of negative appendectomy are still high. The rates of negative appendectomy in males and females differ and are higher in females. In our study, these differences, particularly in females, were studied and possible solutions were discussed. Methods Between October 2002 and October 2009, among women receiving urgent appendectomies, those whose primary cause was gynecological pathology were studied retrospectively. All our women subjects were examined by preoperative gynecologists. After gynecological consultation, the patients were evaluated by a general surgeon due to lack of urgent ultrasonography, computed tomography (CT) and diagnostic laparoscopy and the patient received appendectomy due to acute appendicitis. Results In our series of 1,969 appendectomies, the rate of female/male is 811/1,158. It was determined that the primary cause in 47 (47/811; 5.8%) women with applied appendectomy was gynecological pathology. As a gynecological pathology, it was observed that the most common cause was ovarian cyst ruptures at a rate of 72.3%. The negative appendectomy rate in males was found to be 14.94% (173/1,158), and in females it was 22.56% (183/811). The difference between them is significant (P < 0.01). Of these women, 5.8% were gynecologically-induced and 16.76% were unrelated to gynecological causes. Conclusion We believe that gynecological consultation before appendectomy in women is necessary, but not sufficient. It is also important that at least one of the facilities, such as us, CT, magnetic resonance imaging, and diagnostic laparoscopy should be available in surgical use for the diagnosis of negative appendicitis.

Introduction Laparoscopic cholecystectomy has become the gold standard for the surgical treatment of gallbladder disease. Severe inflammation makes laparoscopic dissection technically more demanding in acute cholecystitis. Conversion to open cholecystectomy due to adverse conditions is still required in some patients. Aim To evaluate predictive risk factors associated with conversion to open cholecystectomy in acute cholecystitis. Material and methods A retrospective analysis was performed on 165 patients who underwent a laparoscopic cholecystectomy for acute cholecystitis in our clinic. Patients who completed laparoscopic cholecystectomy and required conversion to open cholecystectomy were compared in terms of age, sex, fever, laboratory and USG findings, operation timing, complications, and duration of hospital stay. Results There were 53 (32%) male and 112 (68%) female patients; the mean age was 52.4 ±12.5 years. Forty-six (27.9%) of the 165 patients were converted to open cholecystectomy. Male sex of the patients who underwent conversion (47.1%) was found to be statistically significant (p < 0.001). Preoperative white blood count, blood glucose and amylase values, morbidity rate, and hospital stay were raised in patients who underwent conversion, and all were found to be statistically significant (p < 0.05). Conclusions Male sex, blood leucocyte, glucose, and raised amylase emerged as the effective factors for conversion cholecystectomy in our study. These factors should help the clinical decision-making process when planning laparoscopic cholecystectomy in acute cholecystitis. By predicting these risk factors for conversion, preoperative patient counselling can be improved.

Elastofibroma dorsi is a slow-growing, noncapsulated, benign, solid, and soft tissue tumor. It is usually located in the infrascapular region, between the thorax wall and serratus anterior and latissimus dorsi. Although elastofibroma dorsi is usually unilateral, it is also bilateral in 10% of the cases. The pathogenesis of the lesion still remains unclear. Elastofibroma dorsi should be considered in differential diagnosis of soft tissue tumors due to their specific location. As it exhibits benign behavior, it should be surgically removed only in symptomatic patients. A case bilateral elastofibroma dorsi is described and presented.

A clinical case of the penile metastasis from the rectal carcinoma Background. Penile metastases are rare and usually secondary to genitourinary and colorectal cancer. Case report. We present a case of a 77-year-old man with penile metastasis who was operated for rectal carcinoma. He was referred to our clinic for penile ulcerous lesion, semierectile penis and voiding dysfunction. Imaging studies showed nodular lesion at glans penis and multiple bone metastases. He did not respond to chemoradiotherapy and he had bad prognosis. Conclusions. Imaging methods and biopsy may help to clarify the diagnosis but the treatment modalities are insufficient in these patients.

Objective: To present a case of small bowel perforation due to metastatic lung cancer. Case Presentation and Intervention: A 78-year-old male patient, who had been diagnosed with lung cancer 3 months earlier, presented to our clinic with acute abdominal pain. He underwent emergency laparotomy. At surgery, there was a circumferential lesion encompassing the ileum with complete transection. There was no obvious macroscopic appearance of metastatic disease. The involved bowel segment was resected and an ileostomy was performed. Postoperative pathologic analysis confirmed metastatic squamous cell carcinoma metastasis to the ileum, arising from the patient’s lung cancer. Conclusion: This case report showed that small bowel metastases should always be considered in the differential diagnosis of lung cancer patients presenting with acute abdominal pain.
