The aim of this study was to determine whether the use of prophylactic antibiotics had any effects on the development of postoperative surgical wound infections between laparoscopic cholecystectomy patients. Patients who received a single dose of prophylactic antibiotics prior to surgery were included in the prophylaxis group, and those who did not receive preoperative and postoperative intravenous and/or oral antibiotics were included in the no prophylaxis group. A total of 206 patients who underwent laparoscopic cholecystectomy were examined; the infection rate in patients who received prophylaxis was 4.5%, while it was 4.2% in the non‐prophylactic group. There was no statistically significant difference between the groups in terms of infection development rates (P > .05). We suggest that antibiotics should not be given for prophylaxis before low‐risk laparoscopic cholecystectomy as there is no statistically significant difference in the rate of postoperative wound infection among patients who were either given or not given prophylaxis.

Appendectomy is one of the most common surgical procedures. 1 The lifetime risk of developing appendicitis is higher in the second and third decades of life; it is 8.6% in males and 6.7% in females. 2 While acute appendicitis is primarily a disease of the younger population, 5-10% of the cases occur in the elderly population. The probability of developing appendicitis is increasing with the increase in the average life expectancy. 3 The diagnosis of appendicitis is primarily based on the history and physical examination. The differential diagnoses of acute appendicitis are significant. There may be a delay in diagnosis and treatment of elderly patients presenting with abdominal pain since they may have different clinical findings compared to those of younger patients. As a consequence, high morbidity and mortality can occur. 4 Prompt diagnosis and surgical referral will reduce the risk of perforation and prevent complications. Despite all these; in elderly patients, the risk of perforation due to appendicitis is up to 70% and the morbidity and mortality rates are 28-60% and 10%, respectively. 3 Therefore, an exact examination and avoidance of delayed diagnosis are highly important for morbidity and mortality.

Patients who followed-up by observation should be explained that IGM is a chronic disease and that it may recur in certain periods. Clinical, radiological and pathological examinations should be performed together for breast cancer developing due to the chronical progresses of IGM or concurrent breast cancer.

INTRODUCTIONİn this paper, we present a rare case of primary dedifferantiated liposarcoma (DDLS) of the colon, management of which is unclear and difficult to cope with.PRESENTATION OF CASE71 year old female patient with complaints of abdominal pain and swelling was referred to our clinic with the diagnosis of intraabdominal mass. 23 cm × 19 cm × 18 cm tumor starting from the neighborhood of left liver lobe and extending toward pelvic floor was detected on computed tomography. At laparotomy, a multilobulated, soft and yellowish mass was arising from transvers colon and invading greater curvature of stomach. En-bloc removal of the tumor including segmental colon and gastric wedge resection was performed. Postoperative histopathological diagnosis was consistent with dedifferentiated liposarcoma.DISCUSSIONLiposarcomas are rarely encountered in the gastrointestinal tract. Previously, only ten cases of primary liposarcoma of the colon have been reported worldwide and to our knowledge DDLS of transverse colon is the first case reported in the literature. DDLS is a high-grade aggressive tumor carrying the ability to metastasize. Despite complete removal of tumor recurrence is common in DDLS.CONCLUSIONThe constellation of findings in our patient demonstrates that liposarcomas which histologically exhibit dedifferentiation are associated with a poor clinical prognosis and advocating surgery alone is not recommended.

The aim of this study was to investigate the effects of laparoscopic and open surgery on the development of postoperative surgical wound infection and wound healing between complicated appendicitis patients. Patients with complicated appendicitis were divided into those underwent laparoscopic and open surgical procedures according to the surgical method. Patients were followed up with regard to development of any postoperative wound infection, and medical, radiological, and surgical treatment methods and results were recorded. A total of 363 patients who underwent appendectomy were examined, of which 103 (28.4%) had complicated appendicitis. Postoperative wound infection rate in patients who underwent open surgery was 15.9%, while it was 6.8% in the laparoscopic surgery group. There was no statistically significant difference between the two groups in terms of infection development rates (P > .05). The rate of surgical drainage use and rehospitalisation was significantly higher in the group with wound infection than in the group without wound infection. (P < .05). We suggest that in terms of wound infection and wound healing, laparoscopic surgery should be the method of choice for patients with complicated appendicitis. In order to reduce the frequency of wound infection, drains should not be kept for a long time in patients undergoing appendectomy.
