In our article we discussed about fecaliths, fecalith formation, and its aetiological value. Patients which have been operated on for acute appendicitis between 2009-2010 are analysed retrospectively. The average age was 29,3. The number of cases with fecalith was 261 (36,1%). Out of these, 19 acute appendicites, 95 phlegmons, and 30 perforations were detected. Intraluminal pathologies probably play a major role in the development of acute appendicitis. Intraluminal pathological findings may also be seen in healthy persons without necessarily pointing to acute appendicitis. Disease progresses from intraluminal fecalith with no inflammation to perforation from the beginning. There are many explanations regarding the formation of fecaliths. Diagnosis of the fecalith may be decided with ultrasonography, computed tomography and magnetic ...

The case report is important to accumulate knowledge of very rare cases. The diagnosis of the case was established pre-operatively with abdominal computerized tomography (CT) On CT examination, the mass in the hernia sac was not connected with the intestines and a tubal structure on the right side of the uterus was shown to extend out of the abdomen. In the operation, the right uterine tube(RUT) was reduced into the abdomen after its blood supply was shown to be normal. A hernia repair was performed. Sometimes in obese patients, incarcerated femoral or inguinal hernias may not been noted. Ultrasonography, CT and magnetic resonance imaging (MRI) is used frequently to diagnose abdominal wall hernias. The organs in the incarcerated sac must be examined carefully and the viability must be checked. The surgeon must decide whether or not to resect the organs. In our case, strangulation was not found and polypropylene mesh was not used for hernia repair due to a fear of infection of the prosthesis. Incarceration of the uterine tube in the sac is traumatic and this condition may lead to infection. Such conditions may lead to ectopic pregnancy. The patient must be informed about ectopic pregnancy due to a previous incarceration of the tube because ectopic pregnancy may be fatal.

This cell proliferation is not unlimited. Cells take their place in the normal structure depending on macroscopic and microscopic anatomic features of an organ. Cancer develops as the result of mutation of the genes that are responsible for the differentiation and regulation of cell growth. Multiple genes are affected in most tumors. Tumor suppressor genes may lose their function or oncogenes may be activated as a result. Cell proliferation is uncontrolled and unlimited in cancer; it does not comply with the features of the tissue or organ and continues to grow by impairing the structure of the organ. This proliferation exceeds the limits of the organ and continues to proceed toward neighboring organs. After reaching a certain size, a cancer needs vessels for nutrition. Angiogenesis is the main requirement for tumorigenesis. Vascular endothelial growth factor A takes part in this process. All organs and tissues of the body have blood and lymph vessels. Cancer cells grow and impair the wall structure of these vessels. The cells that enter the vessels proceed to distant organs via the vascular structure, reside there, and begin to proliferate, which leads to distant metastasis.
