Pneumoperitoneum is often caused by visceral perforation, and usually manifests with symptoms of peritonitis requiring surgical intervention. Non-surgical spontaneous pneumoperitoneum (ie. not associated with organ perforation) is a rare entity due to intrathoracic, intra-abdominal, gynecologic, iatrogenic or other reasons, and is usually treated conservatively. Idiopathic spontaneous pneumoperitoneum is even rarer than visceral perforation or other causes of free intra-abdominal air. In this report, we present a case of idiopathic spontaneous pneumoperitoneum. A seventy-five-year-old female patient presented with acute abdominal pain, low-grade fever, and nausea. Her abdominal examination findings were vague, and she did not have leukocytosis. Free intra-abdominal air was detected on plain X-ray, she was followed-up with cessation of oral intake, nasogastric tube, fluid resuscitation and prophylactic antibiotics for one day. There were no signs of acute abdomen except diffuse abdominal tenderness by deep palpation on the first day examination. There was a mild leukocytosis with a shift to the left in leukocytes, and pneumoperitoneum on abdominal X-ray. The abdominal computed tomography revealed free intra-abdominal air and minimal free fluid in Douglas pouch. Her past medical history revealed cholecystectomy (10 years ago) with no chronic diseases, regular medications, smoking, or alcohol consumption. The patient underwent emergency laparotomy. Despite lack of an identifiable cause and uncertainty of etiology, the patient was discharged on postoperative day 5. A thorough medical history, appropriate laboratory tests and radiological techniques and physical examination should be combined for identification of patients with non-surgical pneumoperitoneum, and avoid unnecessary laparotomy, while minimally invasive techniques such as laparoscopy should be considered as part of evaluation.

Objective: In line with advances in diagnostic methods and expectation of a decrease in the number of negative laparotomies, selective non-operative management of abdominal gunshot wounds has been increasingly used over the last three decades. We aim to detect the possibility of treatment without surgery and present our experience in selected cases referred from Syria to a hospital at the Turkish-Syrian border. Material and Methods: Between February 2012 and June 2014, patients admitted with abdominal gunshot wounds were analyzed. Computed tomography was performed for all patients on admission. Patients who were hemodynamically stable and did not have symptoms of peritonitis at the time of presentation were included in the study. The primary outcome parameters were mortality and morbidity. Successful selective non-operative management (Group 1) and unsuccessful selective non-operative management (Group 2) groups were compared in terms of complications, blood transfusion, injury site, injury severity score (ISS), and hospital stay. Results: Of 158 truncal injury patients, 18 were considered feasible for selective non-operative management. Of these, 14 (78%) patients were treated without surgery. Other Four patients were operated upon progressively increasing abdominal pain and tenderness during follow-up. On diagnostic exploration, all of these cases had intestinal perforations. No mortality was observed in selective non-operative management. There was no statistically significant difference between Group 1 and Group 2, in terms of length of hospital stay (96 and 127 h, respectively). Also, there was no difference between groups in terms of blood transfusion necessity, injury site, complication rate, and injury severity score (p>0.05). Conclusion: Decision making on patient selection for selective non-operative management is critical to ensure favorable outcomes. It is not possible to predict the success of selective non-operative management in advance. Cautious clinical examination and close monitoring of these patients is vital; however, emergency laparotomy should be performed in case of change in vital signs and positive symptoms concerning peritonitis.

(1) Background: In our study, we aimed to determine the accuracy rates of imaging methods for sigmoid, rectosigmoid colon, and rectum cancer. (2) Methods: Patients with tumors located in the rectosigmoid colon, sigmoid colon, and rectum who were operated on were included. Upon admission, we examined the patients’ first diagnostic colonoscopies and their preoperative repeat control colonoscopies and computed tomography (CT) report. (3) Results: In this study, 23 patients (57.5%) were male. The overall accuracy rates were 80.0% (32/40) in colonoscopy, 65.0% (26/40) in preoperative CT, and 87.5% (35/40) in retro CT, and the differences among the examination methods were statistically significant (p = 0.049). The sensitivity levels decreased to 50.0% for colonoscopy and preoperative CT and 75.0% for retro CT in rectosigmoid colon tumors. In rectal tumors, the sensitivity levels were 75.0% in colonoscopy, 60.0% in preoperative CT, and 80.0% in retro CT. In two patients, the tumor location was given incorrectly, and postoperative pathological evaluations indicated T3N0 tumors; the initially planned treatment was thus changed to include radiotherapy in addition to chemotherapy in the postoperative period because the tumor was located in the middle rectum. (4) Conclusions: Accuracy in tumor localization in sigmoid, rectosigmoid, and rectum tumors still needs to be improved, which could be accomplished with prospective studies. CT evaluations for cancer localization in this patient group should be re-evaluated by a radiologist.

The use of mammography (MM) in breast cancer screening programs has been increasing in recent years. Thus, increasing the number of detected nonpalpable breast cancer patients, through early diagnosis and treatment also increased survival rates. In our study, we wanted to share the factors about imaging-guided exicional biopsies for non-palpable breast lesions in postoperative proven breast carcinoma patients. The surgical data were reviewed for 83 patients with non-palpabl high-risk breast lesions undergoing imaging-guided surgery in our department between January, 2006 and May, 2011. Histopathologic results and age, ultrasound(US) results, MM image results, BI-RADS categorization, localization of lesion(quadrant) were assessed and factors for predicting malignity were detected. Median age was 52 (age range 32–80 years). 29 (34,9%) of patients were malign in histopathologic results. In four patient, re-excision performed because of positive surgical margins. Axillary examination results were normal in 24 (82,7%) of malignant patients. In MM examination; microcalcifications and nodular opasity were diagnosed in 74,6% of patients before surgery. There were no differance about malignity in these groups after surgery (p:0,428). 59% and 32,7% of patients were BI-RADS 4 and 3, respectively. Postoperative diagnosed malignancies in BI-RADS 4 group were significantly higher than BI-RADS 3 group (p:<0,001). In our study; we concluded that, preoperative BI-RADS categorization (US and MM) is correlated with histopathologic findings after surgery and imaging-guided breast surgery is effective for diagnosis of early-stage breast carcinoma.

One of the causes of invagination in adults is primary small bowel lymphoma. Primary small bowel lymphomas are rare, present themselves with complications due to diagnostic difficulties. and are diagnosed only after surgical intervention, In case of invagination, one of the complications of these tumors, namely primary small bowel lymphoma, should also be considered as a cause in the diagnosis, In this paper, the diagnosis and therapy of a rare case of primary polypoid-type small intestinal lymphoma demonstrating findings of obstruction clue to invagination have been presented and discussed in the light of the literature.
