Intramural colonic hemorrhage is rare and often secondary to trauma or anticoagulation therapy. Idiopathic intramural hemorrhages in the alimentary tract have rarely been reported. While several reports of spontaneous perforation of an intramural rectal hematoma have been published, no reports of spontaneous perforation in the ascending colon due to a hematoma have. We describe a patient with an ascending colonic perforation secondary to spontaneous intramural hemorrhage. The patient is a 35-year-old male, who presented with acute abdominal pain and no history of trauma...

An endoscopic mucosal resection (EMR) is an effective and safe therapeutic technique for treating a patient with a laterally-spreading tumor (LST). Colonoscopic-procedure-related complications are noted to be about 2.8% worldwide, and a perforation is the most common. Most colon perforations cause pneumoperitoneum. However, a perforation within the retroperitoneal portion of the colon (rectum and some of sigmoid colon) may cause an extraperitoneal perforation, and the leaking free air may induce pneumoretroperitoneum, pneumomediastinum, and subcutaneous emphysema, depending on the amount of discharged air...

PURPOSE: This study assessed optimal management of colonic diverticulitis as functions of disease location and severity and factors associated with complicated diverticulitis. METHODS: This retrospective review analyzed 202 patients diagnosed between 2007 and 2014 at Chonbuk National University Hospital, South Korea, with colonic diverticulitis by using abdominopelvic computed tomography. Diverticulitis location was determined, and disease severity was categorized using the modified Hinchey classification...

PURPOSE: An intestinal perforation is a rare condition, but has a high mortality rate, even after immediate surgical intervention. The clinical predictors of postoperative morbidity and mortality are still not well established, so this study attempted to identify risk factors for postoperative morbidity and mortality after surgery for an intestinal perforation. METHODS: We retrospectively analyzed the cases of 117 patients who underwent surgery for an intestinal perforation at a single institution in Korea from November 2008 to June 2014...

PURPOSE: This study compared a subtotal colectomy to self-expandable metallic stent (SEMS) insertion as a bridge to surgery for patients with left colon-cancer obstruction. METHODS: Ninety-four consecutive patients with left colon-cancer obstruction underwent an emergency subtotal colectomy or elective SEMS insertion between January 2007 and August 2014. Using prospectively collected data, we performed a retrospective comparative analysis on an intention-to-treat basis...

PURPOSE: Previous studies have demonstrated the prognostic impact of the prognostic nutritional index (PNI), a proposed indicator of immunonutritional statuses of surgical patients, on patients with various gastrointestinal cancers. Although the prognostic impact of the PNI on patients with colorectal cancer has been well established, its value has not been studied in patients treated with preoperative chemoradiation (pCRT). This study aimed to evaluate the prognostic impact of PNI on patients receiving pCRT for locally advanced rectal cancer (LARC)...

Stapled transanal rectal resection (STARR) and stapled hemorrhoidopexy (SH) are well-established techniques for treating rectal prolapse and obstructed defecation syndrome (ODS). Occasionally, they can be associated with severe complications. We describe the case of a 59-year-old woman who underwent STARR for ODS and developed a postoperative pelvic hemorrhage. A computed tomography (CT) scan revealed a vast pelvic, retroperitoneal hematoma and free gas in the abdomen. Laparoscopy ruled out any bowel lesions, but identified a hematoma of the pelvis...

A primary anorectal malignant melanoma is a rare tumor. Moreover, cases involving a synchronous anorectal melanoma and colon adenocarcinoma are extremely rare. The authors report a case of a synchronous anorectal melanoma and sigmoid adenocarcinoma in an 84-year-old man. The regions of the anorectal melanoma showed melanocytic nevi in the adjacent mucosa of the anal canal and rectum. A dysplastic nevus was also identified in the anal mucosa. This case demonstrates that an anorectal melanoma can arise from pre-existing anorectal melanocytic lesions...

PURPOSE: The Korean Society of Coloproctology holds its annual colorectal awareness month every September. This study analyzed the users and the contents of Korean tweets regarding colorectal cancer and estimated the transmissibility of the awareness campaign among Twitter users. METHODS: Prospective data collection was employed to accumulate Korean tweets containing the keywords "colorectal cancer," "colorectal cancer awareness campaign," "gold ribbon," and/or "love handle," from August 1 to September 30, 2014...

PURPOSE: Optimal management of colonoscopic perforation (CP) is controversial because early diagnosis and prompt management play critical roles in morbidity and mortality. Herein, we evaluate the outcomes and clinical characteristics of patients with CP according to treatment modality to help establish guidelines for managing CP. METHODS: Our retrospective analysis included 40 CP patients from January 1, 2003, to December 31, 2014. Patients with CP were categorized into 2 groups according to therapeutic modality: operation (surgery) and nonoperation (endo-luminal clip application or conservative treatment) groups...

PURPOSE: Anismus is a functional disorder featuring obstructive symptoms and paradoxical contractions of the pelvic floor. This study aims to establish diagnosis agreement between physiology and radiology, associate anismus with morphological outlet obstruction, and explore the role of sphincteric pressure and rectal volumes in the radiological diagnosis of anismus. METHODS: Consecutive patients were evaluated by using magnetic resonance imaging proctography/fluoroscopic defecography and anorectal physiology...

PURPOSE: This study was conducted to identify the effectiveness of a preoperative comprehensive geriatric assessment (CGA) for predicting postoperative morbidity in elderly patients who underwent surgery for colorectal cancer. METHODS: Elderly patients (≥70 years old) who underwent surgery for colorectal cancer at a tertiary hospital in Korea were identified, and their cases were analyzed using data from a prospectively collected database to establish an association between major postsurgical complications and 'high-risk' patient as defined by the CGA...

Acute ischemia of the rectum or anal canal resulting in necrosis is extremely uncommon because both the rectum and the anal canal have excellent blood supplies. We present a case with spontaneous necrosis of the anal canal without rectal involvement. Surgical debridement was accomplished, and the recovery was uneventful. The patient was elderly, with probable atherosclerotic arterial disease, and presented with hypotension. Due to the lack of other precipitating factors, the hypoperfusion hypothesis seems to be the most suitable in this case...
