Purpose: The aim of this study was to examine the usefulness of positron emission tomography (PET)-computed tomography (CT) in the pre-operative staging of gastric cancer. Materials and Methods: Between February 2006 and August 2008, PET-CT and CT were performed on 70 patients diagnosed with gastric cancer by gastrofiberscopic biopsy. The sensitivities, specificities, Positive predictive value (PPV), and negative predictive value (NPV) of PET-CT and CT imaging for the detection of gastric cancer TNM staging were compared. Results: The detection rates for the primary tumor were as follows: PET-CT, 81.4% (57/70); and CT, 42.9% (30/70). For both early gastric cancer (EGC) and advanced gastric cancer (AGC), PET-CT was more accurate than CT in detecting the lesions. As the size of the tumor exceeded 3 cm, the detection rate increased. The sensitivities, specificities, PPV, and NPV of PET-CT for lymph node staging were 55.6%, 81%, 86.2%, and 45.9%, while the sensitivities, specificities, PPV, and NPV of CT were 40.0%, 85.7%, 85.7% and 40%, respectively. One case of multiple liver metastasis and two cases of dual primary cancer (rectal and pancreatic cancers) were detected by PET-CT. PET-CT also had a higher detection rate for all histologic types of primary tumors. PET-CT was more accurate than CT in detecting primary gastric cancer lesions. The detection of nodal metastasis by PET-CT was similar to CT; small-sized tumors or EGC detection rates were not high. However, PET-CT provided additional information to detect distant metastases and dual primary cancers and reduced unnecessary laparotomies to detect peritoneal seeding or carcinomatosis. Conclusion: It would be useful to make a pre-operative diagnosis of gastric cancer and determine treatment if PET-CT were added to other routine pre-operative studies.

Background: Traumatic aortic rupture is a highly fatal condition in which a patient's outcome is strongly affected by other associated injuries. Selection of the appropriate surgical timing and the management plan is important. Material and Method: The medical records of the 15 traumatic descending thoracic aortic rupture patients who underwent the clamp & sew technique were retrospectively reviewed and checked for the presence of associated injuries and the postoperative course. Result: The hospital mortality was 6.07% (one patient). This patient died intra-operatively and the cause of the death was delayed hemoperitoneum. The mean operative time and aortic clamp time were $231{\pm}53.1$ and $13.1{\pm}5.3$ minutes, respectively. One patient complained the bowel obstructive symptoms at postoperative 10 days. We found the mechanical bowel obstruction on computed tomography of the abdomen, and segmental bowel resection was done. Conclusion: Although several surgical strategies may be appropriate for managing traumatic aortic rupture, the clamp & sew technique is a safe and effective method for the treatment of traumatic aortic injury.

Purpose: This study aim to determine the effect of chewing gum on the reduction of postoperative ileus and recovery after surgery. Methods: The study was conducted as a randomized controlled trial among 82 patients who underwent spine surgery between May 2015 and October 2015. Patients in experimental group chewed sugarless gum 3 times daily for 30 minutes each time until POD 5. Abdominal discomfort, the first defecation, and CAS score (Constipation Assessment Scale) were monitored. Results: After the experiment, abdominal discomfort was significantly decreased in the experimental group compared to that of the control group (F=2.46, p=.044). However, the first defecation occurred on postoperative hour 69.6 in the chewing gum group and on hour 60.2 in the control group (t=-1.63, p=.107). CAS was significantly decreased in the experimental group compared to that of the control group (F=3.51, p=.012). Conclusion: Chewing gum is expected to help patient recover after surgery as safe nurse intervention which can reduce abdominal discomfort and constipation during early postoperative days after spine surgery.

Spontaneous intraperitoneal extravasation of urine is rare. Perirenal urinoma may develop when obstruction to urinary flow creates sufficient back pressure to produce extravasation of urine. Urinary ascites most commonly indicate a disruption to the integrity of the urinary tract. We report a case of urinary ascites with urinoma resulting from an ureteropelvic junction obstruction in a neonate.

A peritoneal loose body is reported to develop because of torsion and separation of the epiploic appendages. The condition is usually symptomless and may be incidentally during abdominal surgery or autopsy. It usually occurs in middle-aged and elderly adults and is very rare in children. In this paper, we report a case of a peritoneal loose body in the pelvic cavity of a 10-year old-girl who presented with urinary frequency and left lower abdominal discomfort. A second plain X-ray film of the abdomen, obtained before surgery, in a different view than the first, revealed that the calcified mass had migrated to a lower position. The mass was laparoscopically resected, and histological examination revealed it to be a fibrotic nodule with central liquefaction and calcification.

The development of different entities of soft tissue sarcoma in one patient is rare. It usually affects head and neck or abdominal region, whereas those affecting the extremities are much rarer. We describe a patient with double primary presentation of liposarcoma and Ewing's sarcoma in extremity. This case implies that sarcoma patients are at increased risk of a second malignancy, and this implies a need to search for occult tumors during follow up.

A successful resection of dissecting thoracoabdominal aortic aneurysm is presented in a patient who had undergone kidney transplantation 20 months previously. Because the transplanted kidney is more sensitive to ischemia than the normal kidney, a femoro-femoral bypass with a pump oxygenator was used for perfusion of the transplanted kidney during crossclamping. During the clamping time of 1)8 minutes, kidney perfusion was maintai ed with a perfusion pressure of (19 to 31) 27mmHg and the flow was 0.53 to 0.81 L/min. 32mm sized Hemashield (22 Cm in length) was interposed. The postoperative course was uncomplicated. We believe that performing the femoro- femoral bypass with a pump oxygenator is an effective and simple method for renal and spinal protection in such operations.

We have experienced two cases of mycotic aneurysms of the superior mesenteric artery The first case originated from septic embolism of Infective endocarditis and the second case originated from salmonella enteritis eight months before The aneurysms were diagnosed by abdominal ultrasonography and comflrmed by computed tomogram and dngiography but the blood culture was negative in both cases at the time of the surgery. Both patient ere successfully treated by resection only and the restorations of vdsculdr continuity were not neccesary because of adequate collateral circulations to the intestine. Both pd.tient's postoperative courses were uneventful after the follow up of one year and nine months, respectively.

Primary peritoneal psammocarcinoma is a rare type of serous carcinoma that is characterized by the massive formation of psammoma bodies and the invasion of adjacent organs. A 55-year-old female who previously underwent a hysterectomy presented to the emergency room with severe abdominal pain. Contrast-enhanced CT revealed an intra-abdominal calcific mass. Initially, it was thought to be a heterotopic ossification due to the previous pelvic surgery with intact ovaries. However, this was diagnosed as a primary peritoneal psammocarcinoma. Primary peritoneal psammocarcinoma is a very rare disease entity that should be considered a differential diagnosis in patients with normal ovaries, massive ossification in the pelvic cavity, and calcific peritoneal nodules.

Background: Intralobar and extralobar pulmonary sequestrations have been considered as congenital lesions that occur at different stages of embryonic life. However, most cases of intralobar pulmonary sequestration (IPS) seem to have an acquired origin, as they are absent in infants and associated anomalies are relatively, uncommon among them. Material and Method: The cases of 25 patients who were diagnosed as IPS after surgical resection from December, 1985 to July, 2002 were included in this study. The medical records wire retrospectively reviewed and the clinical characteristics were age at operation; gender; symptoms at presentation; presence of congenital anomalies; combined diseases; preoperative studies and diagnosis; location of the lesion; method of surgical resection; origin, size and numbers of aberrant artery; histopathological findings; and postoperative complications. Result: There were 17 (68%) female patients and 8 (32%) male patients, their ages ranged from 1 to 57 and mean value was 23 years old. Though 14 patients (56%) complained of respiratory symptoms such as pneumonia and recurrent respiratory infections, a large number of patients (44%) were asymptomatic or had chest pain only when the lesion was discovered. Only 8 patients (32%) were diagnosed as pulmonary sequestration preoperatively and 8 (32%) were suspected as mediastinal or lung tumor, 5 (20%) were congenital or acquired cystic lung disease, and 4 (16%) were lung abscess or bronchiectasis, respectively. The majority of aberrant arteries (86.4%) confirmed during the operation were originated from thoracic aorta and 2 were thoracic and abdominal aorta, 1 was abdominal aorta, respectively. The younger patients (less than 10 years old) had more other congenital anomalies (30% vs 6.7%) but the proportion of congenital IPS was not significantly different (10% vs 6.7%, p>0.05) compared with elder patients. Histopathologically, almost all lesions showed chronic inflammation, cystic changes and similar pleural adhesions regardless of age. Conclusion: The large portion of the patients with IPS (44%) was clinically asymptomatic or presented non-respiratory symptoms at diagnosis and likely to be diagnosed as mediastinal or lung tumor especially in elder patients. Though the younger patients had more other congenital anomalies, most cases of IPS proved to be acquired lesions in terms of the histopathlogical findings and the proportion of congenital evidences.
