Extremely rare presentation of an omphalomesenteric cyst in a 61-year-old patient.

The umbilicus is remaining scar tissue from the umbilical cord in the fetus. If the omphalomesenteric duct in the umbilicus is not properly closed, an ileal-umbilical fistula, sinus formation, cysts, or, most commonly, Meckel's diverticulum can develop. The others are very rare and mostly occur in the pediatric population. We describe herein a 61-year-old female with a giant omphalomesenteric cyst presented as an asymptomatic infraumbilical mass. To our knowledge, this is the oldest patient reported and the largest cyst described in the literature. The diagnosis of a painless abdominal mass frequently suggests malignancy in older patients. But, extremely rare conditions can be detected, such as an omphalomesenteric cyst.

Effects of preoperative nutritional support on colonic anastomotic healing in malnourished rats.

OBJECTIVE: It has been proven that malnutrition increases postoperative morbidity and mortality, and it may also negatively affect wound healing in the gastrointestinal tract. In the literature, there is only one study evaluating the effects of preoperative nutritional support on colonic anastomotic healing under malnourished conditions. In order to improve the data on this topic, an experimental study was planned to evaluate the effects of preoperative nutritional support on colonic anastomotic healing in malnourished rats. MATERIAL AND METHODS: The study included 18 male Wistar albino rats divided into 3 groups. The control (C) group was fed ad libitum for 21 days. The malnutrition (M) group and preoperative nutrition (P) group were given 50% of the daily food consumed by the rats in Group C for 21 days to induce malnutrition. At the end of 21 days, Group P was fed ad libitum for 7 days (preoperative nutritional support). Colonic transection and end-to-end anastomosis was performed at 21 days in Group C and Group M and at 28 days in Group P. The rats were sacrificed at postoperative 4 days, anastomotic bursting pressure was measured, and samples were taken to analyze tissue hydroxyproline levels. RESULTS: Anastomotic bursting pressure was significantly higher in Group C than in Group M and Group P (p<0.05), and it was significantly higher in Group P than in Group M (p<0.05). Tissue hydroxyproline levels in Group P were found to be significantly higher than those in Group M and Group C (p<0.05). CONCLUSION: One week of preoperative nutritional support increases collagen synthesis in the colon and positively affects anastomotic healing under malnourished conditions.
