BACKGROUND: Since its introduction, robotic surgery has been applied actively in several fields of minimally invasive surgery, and its use in the field of colorectal surgery is also increasing. In the studies to date, feasibility and safety have been the main focus, but the economics involved are important to examine. We compared the economics of robotic surgery with those of laparoscopic surgery for rectal cancer. MATERIAL AND METHODS: We analyzed the clinical characteristics, total hospital ch

BACKGROUND: Bone metastasis in patients with colorectal cancer (CRC) is very rare, and data are extremely lacking. We aimed to evaluate the characteristics of bone metastasis in patients with CRC. MATERIALS AND METHODS: We performed a chart review of 63 patients (1.1 %) with bone metastasis among 5479 patients who underwent surgery for CRC. RESULTS: Most patients were stage 3 (17.5 %) or 4 (73.0 %), and 32 patients (50.8 %) were diagnosed with bone metastasis at initial diagnoses of CRC. Thirty-

BACKGROUND/AIMS: Diversion colitis is the inflammation of the excluded segment of the colon in patients undergoing ostomy. It has been suggested that a change in colonic flora may lead to colitis; however, direct evidence for this disease progression is lacking. The aim of this study was to evaluate the relationship between the severity of diversion colitis and the composition of colonic bacteria. METHODS: We used culture methods and polymerase chain reaction to analyze the colonic microflora of

Trans-anal reinforcing sutures may reduce the need for diverting ileostomy. A randomized prospective study with a larger population should be performed in the future to demonstrate the efficacy of trans-anal reinforcing sutures.

Since its introduction, robotic surgery has been rapidly adopted to the extent that it has already assumed an important position in the field of general surgery. This rapid progress is quantitative as well as qualitative. In this review, we focus on the relatively common procedures to which robotic surgery has been applied in several fields of general surgery, including gastric, colorectal, hepato-biliary-pancreatic, and endocrine surgery, and we discuss the results to date and future possibilit

Patients treated surgically for intestinal Behçet disease frequently have postoperative complications and the need for a stoma and have a high risk of recurrence.

BACKGROUND: Preoperative chemoradiotherapy (CXRT) is performed to reduce local recurrence and improve the rate of radical resection for rectal cancer. Currently, it is recommended for all suspected T3 rectal cancers. However, the survival benefit of this procedure is controversial, and complications of RT are often overlooked. The present study was designed to assess the validity of our institutional policies regarding selective use of preoperative CXRT for T3 rectal cancer. METHODS: From Septem

BACKGROUND: Incidental visualization of indeterminate pulmonary nodules is considered a clinical dilemma. METHODS: We identified patients for inclusion in this study by searching for the term "indeterminate nodules" in the radiology database of rectal cancer patients who underwent surgery. Patients with definite metastatic disease were excluded. RESULTS: In total, 224 patients underwent chest computerized tomography (CT) and 59 of these patients had indeterminate pulmonary nodules detected more

Here, we present the case of a 53-year-old man with a hepatothorax due to a right diaphragmatic rupture related to duodenal ulcer perforation. On admission, the patient complained of severe acute abdominal pain, with physical examination findings suspicious for a perforated peptic ulcer. Of note, the patient had no history of other medical conditions or recent trauma, and the initial chest radiography and laboratory findings were not specific. A subsequent abdominal computed tomography revealed
