Enterocutaneous (EC) fistula is an abnormal connection between the gastrointestinal (GI) tract and skin. The majority of EC fistulas result from surgery. About one third of fistulas close spontaneously with medical treatment and radiologic interventions. Surgical treatment should be reserved for use after sufficient time has passed from the previous laparotomy to allow lysis of the fibrous adhesion using full nutritional and medical treatment and until a complete understanding of the anatomy of

SPLS for colon cancer is feasible and can be performed by following oncologic principles. However, surgeons should be aware of the potential for unexpected adjacent organ injury ( ClinicalTrial.gov identifier: NCT01203969).

Abstract Background Prevention and early detection of colorectal cancer (CRC) is a global priority, with many countries conducting population-based CRC screening programs. Although colonoscopy is the most accurate diagnostic method for early CRC detection, adherence remains low because of its invasiveness and the need for extensive bowel preparation. Non-invasive fecal occult blood tests or fecal immunochemical tests are available; however, their sensitivity is relatively low. Syndecan-2 ( SDC2

Situs inversus totalis (SIT) is a very rare condition. Laparoscopic surgery in a patient with SIT is difficult because the surgeon's dexterity is compromised during the procedure, and the patient's anatomy is the mirror image of normal. We present a SIT patient who underwent laparoscopic abdominoperineal resection for rectal cancer. The detailed operative procedures and trocar placement considerations are described.

Recent advances in the management of rectal cancer have dramatically changed the clinical practice of colorectal surgeons because the main focus of rectal cancer treatment has changed from sphincter-saving to an organ-preserving strategies. Modifying the delivery of systemic chemotherapy to improve patients' survival is another progress in colorectal cancer management, known as total neoadjuvant therapy (TNT). TNT is a new strategy used by colorectal surgeons to improve the quality of life and s

The endo-Satinsky clamp is a useful device for rectal transection and irrigation. The use of this device makes it easier to place an endostapler just distal to the clamp and to transect the rectum in a more appropriate position.

INTRODUCTION: Noninvasive stool DNA-based methylation testing has emerged as an effective strategy for the early colorectal cancer (CRC) detection. Syndecan-2 ( SDC2 ) methylation frequently occurs in all stages of CRC; therefore, the aim of this study was to evaluate the clinical performance of a stool DNA-based SDC2 methylation test for detecting CRC in asymptomatic or high-risk CRC populations. METHODS: This multicenter prospective study was conducted to determine the clinical performance of

With the life span of the general population increased, rectal prolapse in elderly patients became a major concern in terms of the decision of the treatment modalities and quality of life of patients. Most elderly patients with rectal prolapse in the past received a perineal approach with the fear of general anesthetic complications rather than the abdominal approach. However, improvement in perioperative care in anesthesiology and minimally invasive surgery, the trend of surgical management of

The current standard of care for treating patients with locally advanced rectal cancer includes preoperative chemoradiation therapy (PCRT) followed by a total mesorectal excision and postoperative adjuvant chemotherapy. A subset of these patients has achieved a pathologic complete response (pCR) and they have shown improved disease-free and overall survival compared to non-pCR patients. Thus, many efforts have been made to achieve a higher pCR through PCRT. In this review, results from various o

The coronavirus disease 2019 (COVID-19) pandemic has dramatically changed our daily lives and medical practices since it was first reported in December 2019 in Wuhan, China. Unlike the usual transmission patterns of other viral diseases, the asymptomatic or presymptomatic transmission of COVID-19 has caused difficulties in disease control around the globe. Surgical smoke or fumes may carry viruses. However, there is no evidence that the severe acute respiratory syndrome coronavirus 2, which caus

Stoma operations are one of the most frequently performed operation by the colorectal surgeons. And the consequences of the stoma operation of the patients are well known. However, most colorectal surgeons who performed stoma operation were not aware of the problems that are part of the rehabilitation of the ostomates. In order to elucidate the current status of the stoma studies in Korea, literature reviews were performed by using the Korean medical literature database. Most of the Korean liter

Pathologic evaluation of the resected specimen is a critical component when managing the patients with rectal cancer, from initial diagnosis through definitive treatment. The best estimation of prognosis in rectal cancer is related to the anatomic extent of disease determined by pathology. Although a large number of staging system has been developed for rectal cancer over the years, use of TNM staging system of the AJCC (American Joint Committee on Cancer) and the UICC (International Union Again
