    Abstract Jejunal diverticulosis is a rare case that is diagnosed incidental. Although it is generally asymptomatic, it can cause non-spesific symptoms like stomachache, nausea, diarrhoea, malabsorption, bleeding, obstruction and / or perforation. Perforated jejunal diverticulitis is a very rare acute abdomen cause. The acute complications of jejunal diverticulosis can be cause of significant morbidity and mortality especially in old patients. In this text, we report a 81 year old woman case that was operated emergently because of perforated jejunal diverticulitis and was lost in postoperation term because of multiple organ failure.

    Abstract Breast cancer is the most common cancer in women. One in eight women reached at the age of 85 (13,4 %), are at risk of developing breast cancer. 5-10% of breast cancers inherited and passes germline mutations such as BRCA-1 and BRCA-2. In mutation carriers, lifetime risk of developing breast cancer is 90%, the risk of developing ovarian cancer is 40%. In existing protection ways, prophylactic mastectomy is the most effective way to reduce risk of breast cancer occurrence. In this study, we aimed to present a 39 years old woman case who detected high risk of developing lifetime breast and ovarian cancer after BRCA genes analyze and performed prophylactic bilateral oophorectomy and bilateral mastectomy.

    Abstract Ectopic adrenal tissue is a benign lesion generally determined incidentally during a surgical intervention applied for another reason. This tissue may be present along the path of the testicles and groin discovered during surgery. While the condition has been mainly reported in the pediatric population, it is very rarely reported in adults. The aim of this study was to present an adult patient with ectopic adrenal tissue which was determined incidentally within an indirect inguinal hernia sac.

    Abstract Endometriosis is characterized by the presence of histologically normal endometrial tissue outside the uterine cavity. Endometriotic implants are usually located in the pelvic organs, but they have been described in almost every location of the female body. It may also be present after cesarean section or other gynecological operations. In this study, we reported a rare case of endometriosis located in an indirect inguinal hernia sac.

    Abstract The most frequent postoperative complication after breast surgery is seroma formation. Seroma occurs due to lymphatic and vascular fluid leakage into the dead space created by surgical dissection. The objective of the research was to evaluate the effects of local fibrin glue, tetracycline, talc applications, and flap fixation technique on reducing seroma formation after mastectomy and axillary dissection. In addition, we aimed to determine the level of efficacy for these applications, as well as to identify the most appropriate method to be used in operations with high risk of seroma formation. Materials and Methods. This experimental study was conducted using a total of 60 female Wistar albino rats. They were allocated into six groups and each comprised ten rats. Unilateral mastectomy and axillary dissection were performed on all the rats. Local applications of fibrin glue, tetracycline, talc, and alcoholic iodine were performed in four separate groups. Flap fixation technique was applied in one group and those rats that did not receive any intervention constituted the control group. On the 10th postoperative day, seroma was aspirated under anesthesia, and the amount of seroma fluid was recorded. Seroma fluid was analyzed for interleukin 1-β, vascular endothelial growth factor, and C-reactive protein levels. Tissue samples were obtained from the skin overlaying the dissection area, the axilla, and the thoracic wall. Wound healing was evaluated with histopathological examination. Results. Seroma volume was lower and the wound healing scores were the highest in the flap fixation group and the tetracycline group as compared to the control group. However, the alcoholic iodine group and the talc group had a greater amount of seroma (p < 0.05). There was no difference between the fibrin glue group and the control group. Conclusions. In our mastectomy model, local application of alcoholic iodine and talc substances caused more wound site problems and postoperative seroma formation. While fibrin glue did not cause ...

    Abstract Spontaneous extrahepatic bile duct perforation is generally seen in infants. Although rarely seen in adults, it may be seen with fatal bile peritonitis. Therefore, for a patient presenting with acute abdominal symptoms, differential diagnosis must be made with radiological imaging such as abdominal ultrasonography or computed tomography, without any loss of time. In these imaging tests, in cases of gallstone disease together with perihepatic free fluid or choledocus which can not be monitored, it should be considered in the differential diagnosis. An emergency surgical intervention should be planned to avoid serious complications. The aim of this paper was to present the rare cause of acute abdomen which developed associated with spontaneous common hepatic canal perforation in an adult.

    Abstract Breast cancer is the most frequently seen cancer in females but primary neuroendocrine carcinoma of the breast, which was defined as a separate entity in the 2003 World Health Organisation tumour classification, is seen extremely rarely. This entity, which is still not well-defined and has not been well-researched, demonstrates a more aggressive course than invasive ductal carcinoma. As metastatic breast neuroendocrine tumours are more widespread and the treatment strategy is different, preoperative differential diagnosis is important. The basic diagnostic method is pathological examination. If a neuroendocrine pattern is determined in microscopy, then immunohistochemical study of neuroendocrine markers should be made. It is necessary to be vigilant in terms of synchronous tumours and metachronous tumours which may develop in the postoperative period as the incidence of synchronous and metachronous cancers in patients with neuroendocrine tumours is higher compared to the general population. The case presented here is of a 73-year old patient who presented with complaints of a breast lump, which was thought to be invasive breast cancer, and as a result of the operation with pathological and immunohistochemical examination, primary neuroendocrine carcinoma of the breast was determined. With more advanced evaluations, no synchronous or metachronous tumours were determined.

    Abstract Although it is mostly observed in childhood, swallowing foreign bodies causes morbidity and mortality of a high percentage in the adult age group. Swallowed foreign bodies can be both harmless as well as life-threatening. The number, shape, size, and time of the swallowed foreign body to get deposited in the specific location determines the type of treatment. Late diagnosis and treatment is an important problem that causes perforation and obstruction. In this article, we presented a 39-year-old male patient who swallowed his denture while sleeping.

    Abstract BACKGROUND We evaluated the hematological, biochemical, and histopathological effects of Montelukast on pancreatic damage in an experimental acute pancreatitis model created by cerulein in rats before and after the induction of pancreatitis. MATERIAL AND METHODS Forty rats were divided into 4 groups with 10 rats each. The study groups were: the Cerulein (C) group, the Cerulein + early Montelukast (CMe) group, the Cerulein + late Montelukast (CMl) group, and the Control group. The pH, pO2, pCO2, HCO3, leukocyte, hematocrit, pancreatic amylase, and lipase values were measured in the arterial blood samples taken immediately before rats were killed. RESULTS There were statistically significant differences between the C group and the Control group in the values of pancreatic amylase, lipase, blood leukocyte, hematocrit, pH, pO2, pCO2, HCO3, and pancreatic water content, and also in each of the values of edema, inflammation, vacuolization, necrosis, and total histopathological score (P<0.05). When the CMl group and C group were compared, no statistically significant differences were found in any parameter analyzed. When the CMe group was compared with the C group, pancreatic amylase, lipase, pH, PO2, pCO2, HCO3, pancreatic water content, histopathological edema, inflammation, and total histopathological score values were significantly different between the groups (P<0.05). Finally, when the CMe group and the Control group were compared, significant differences were found in all except 2 (leukocyte and pO2) parameters (P<0.05). CONCLUSIONS Leukotriene receptor antagonists used in the late phases of pancreatitis might not result in any benefit; however, when they are given in the early phases or prophylactically, they may decrease pancreatic damage.
