ABSTRACT
AIMS: Retrorectal tumors are rare, mostly benign tumors and named due to their localization. Diagnoses of these tumors are usually delayed because of nonspecific complaints and symptoms. Magnetic resonance imaging has beneficial uses both for diagnosis and treatment. In this study, we reviewed a case series of retrorectal tumors. SUBJECTS AND METHODS: The patients who were diagnosed with retrorectal tumors between 2008 and 2015 were analyzed. This investigation was conducted at a Tertiary Education and Research Hospital. Sixteen patients were included in this study. Patients' demographic data, imaging workups, surgical operation reports, pathologic examination results, postoperative complications, and follow-up results were examined. Descriptive statistics, median, and standard deviation for continuous variables were used. The primary outcomes measured were diagnostic conflict, knowledge, and preference for surgery. STATISTICAL ANALYSIS USED: Definitive statistical methods (mean, standard deviation, median, frequency, and percentage) were used to evaluate the study data. RESULTS: One patient refused operation and one was in preoperative preparation period. Fourteen of sixteen patients were operated. Two (14.3%) of operated patients have malignant histopathological result (one gastrointestinal stromal tumor, one ganglioneuroblastoma). Rest of the operated patients' histopathological reports was as follows: Four schwannomas, three epidermoid cysts, two tailgut cyst, one dermoid cyst, one teratoma, and one angiomyolipoma. Eight patients were operated by posterior incision, five patients with transabdominal approach, and one patient with combined approach. CONCLUSIONS: Retrorectal tumors are rare cases, and treatment of retrorectal tumors is surgery and should be operated in referenced hospitals to avoid diagnostic and therapeutic problems.

CONTEXT: Colorectal cancers are frequent among cancers of gastrointestinal system. Whether there are any differences between survival in rectum and colon cancer patients is controversial. AIMS: In this study, we aimed to compare survival in surgically treated rectum and colon cancers and determine the factors affecting survival. SUBJECTS AND METHODS: The patients with colon and rectum cancer operated between 2009 and 2013 were examined retrospectively using prospective database. Patients were categorized as colon and rectum according to the tumor's location. Survival was identified as the primary outcome. Kaplan-Meier survival analysis and log-rank tests in survival assessment were used. RESULTS: One hundred and sixty-one patients with a mean age of 62.8 ± 12.7 years were included in the study. Male/female ratio was 1.6. Colon and rectum patients were counted as 92 (%57.1) and 69 (%42.9), respectively. Both groups were similar in demographic data (P > 0.05). It was observed that in 46 months (mean) of follow-up, 39.7% (n: 64) died, and 60.3% (n: 97) survived. Median survival time was 79 months, and 5-year cumulative survival rate was 60.8%. Five-year cumulative survival rates in stages for 1, 2, 3 and 4 were 88.2%, 64.7%, 48.5%, and 37.0%, respectively. It was noted that median survival time for colon cancer was 78 months and for rectum cancer was 79 months. Five-year cumulative survival rates for colon and rectum cancers were calculated as 56.7% and 63.4%, respectively. There were no significant differences in colon and rectum cancers in the means of survival rate (P: 0.459). CONCLUSIONS: While location of colorectal cancers shows no significant effect on survival, treatment in the early stages increases survival rate.

Hydatid disease is caused by Echinococcus granulosus. Hydatid cysts are commonly located in the liver and lungs. The occurrence of pancreatic hydatid cysts is very rare, even in endemic areas. Sinistral portal hypertension, which is rarely seen, occurs when a pathological process causes splenic vein occlusion. A 26-year-old male patient presented with abdominal pain. He had a history of operation for hydatid cyst of the lung 15 years ago. A left thoracotomy incision scar was observed during his physical examination. Laboratory findings revealed no abnormalities. Abdominal ultrasonography revealed a 96×69-mm lobular, contoured, well-circumscribed cystic lesion with thickened septation. Abdominal magnetic resonance imaging revealed a 100×76-mm smooth, bordered cystic lesion containing septations in the body and tail of the pancreas compressing the splenic artery and vein, causing sinistral portal hypertension. Dilatation was noted in the left gastroepiploic vein. The patient underwent cystotomy. Pancreatic fistula developed during the postoperative follow-up. The patient was discharged in 20 days without postoperative complications. No complications were observed during the follow-up period of 7 months. Surgery should be considered as a more conservative approach.
