BACKGROUND: Melanoma metastatic to the large bowel (colon, rectum, and anus) is rarely diagnosed, with more than 95% of large bowel metastases identified post-mortem. The incidence, natural history, and survival rates of patients with large bowel melanoma metastases are poorly documented in the literature. OBJECTIVE: This study aimed to identify the incidence, clinical characteristics, and survival of patients with large bowel melanoma metastases. METHODS: A review was undertaken of all patients with melanoma treated over a 50-year period (1964-2014) at a tertiary referral center...

Approximately 10-20% of inflammatory bowel disease (IBD) cases are diagnosed after 60 years of age. Due to the high prevalence of conditions mimicking IBD at older age - including bowel disease associated with non-steroidal anti-inflammatory drugs, diverticulitis, and microscopic colitis - differential diagnosis of IBD among older adults is frequently delayed. Late-onset IBD is characterized by a predominance of colonic disease and an overall milder disease course; disease progression and new intestinal manifestations are rare...

REVIEW
Lily S Cheng, Allan M Goldstein
Constipation is a common childhood problem, but an anatomic or physiologic cause is identified in fewer than 5% of children. By definition, idiopathic constipation is a diagnosis of exclusion. Careful clinical evaluation and thoughtful use of imaging and other testing can help exclude specific causes of constipation and guide therapy. Medical management with laxatives is effective for the majority of constipated children. For those patients unresponsive to medications, however, several surgical options can be employed, including anal procedures, antegrade colonic enemas, colorectal resection, and intestinal diversion...

BACKGROUND: Colorectal cancer is the fourth most diffuse cause of death in the world and local recurrence is associated with a reduced long-term life expectancy, with a reduced quality of life. Rectal washout at the anastomosis site leads to a statistically significant reduction of local recurrences. METHODS: We developed the idea of a new laparoscopic stapler with an integrated washout system that could decontaminate the rectal stump before resection, without the need to enlarge the standard surgical incision or even to distort the incision site, closing the rectal stump just below the inferior part of the cancer, and then proceeding with the resection and stapling of the distal part of the tumor...

Importance: Patients with familial adenomatous polyposis (FAP) are at markedly increased risk for colorectal polyps and cancer. A combination of sulindac and erlotinib led to a 71% reduction in duodenal polyp burden in a phase 2 trial. Objective: To evaluate effect of sulindac and erlotinib on colorectal adenoma regression in patients with FAP. Design, Setting, and Participants: Prespecified secondary analysis for colorectal adenoma regression was carried out using data from a double-blind, randomized, placebo-controlled trial, enrolling 92 patients with FAP, conducted from July 2010 to June 2014 in Salt Lake City, Utah...

Anal metastasis of colorectal cancer is rare, and no standardized effective therapeutic strategy exists. We report a case of abdominoperineal resection for anal metastasis of rectal cancer. A 65-year-old man underwent laparoscopic low anterior resection for rectal cancer in August 2013. Histopathological examination revealed a moderately differentiated adenocarcinoma( tub2, pSS, ly3, v2, pN1, H0, P0, M0, Stage III a, Cur A). In February 2015, he complained of anal discomfort, and tumor markers were elevated...

Clinical investigation in minimally invasive gastrointestinal surgery has been developed by leaps and bounds in 2017. Standardizations of port placement, surgical approaches, lymphadenectomy, reconstruction, total laparoscopic surgery, incision-free technique, 3D laparoscope, as well as robotic surgeries, have been established. In the treatment for gastric cancer, the first-hand data of the laparoscopic technique for advanced gastric cancer will be released soon. Therefore, the research hotspots have been moved forward to lymphadenectomy, resection range, and reconstruction in laparoscopic advanced gastric cancer surgery...

Background: The role of surgery in treating children with functional constipation (FC) is controversial, because of the efficacy of bowel management programs. This case series is comprised of failures: 43 children, spanning 25 years' practice, who had megarectosigmoid (MRS) and unremitting constipation. Purpose: To determine whether these children were helped by surgery, and to contribute to formulating a standard of care for children with megarectum (MR) and/or redundancy of the sigmoid colon (MS) who fail medical management...

Mutations in the BRCA1/2 genes were recently shown to be associated with an increased risk for colorectal cancer. We characterized the largest cohort available of BRCA1/2 mutation carriers with colorectal cancer. We analyzed 32 patients with lower gastrointestinal cancers and germline BRCA1/2 mutations from two large academic hospital registries; 91% of patients were of Ashkenazi ancestry, 78% were women, and 62.5% were carriers of BRCA1 gene mutations. A high percentage of colorectal tumors (34.5%) had a mucinous histology and were located atypically in the left colon...

AIMS: Hepatic progenitor cells (HPCs) are activated in various liver diseases, but their role in the carcinomatous environment remains unknown. We aimed to identify the possible presence and topography of HPCs in liver metastases. METHODS AND RESULTS: We examined 14 liver resection specimens for colorectal adenocarcinoma (n = 13) and anal squamous cell carcinoma (n = 1) metastases. Immunohistochemical markers of colonic origin (keratin 20 and CDX2) and squamous cell origin (p63), HPC [keratin 19 (K19) and CD56] and stem cell (CD44) markers, and the biliary marker keratin 7 (K7), which may also highlight HPCs, were applied on routinely processed tissue sections...

Diverticular colitis is chronic inflammation of the colon where diverticula are present. The endoscopic and histopathological findings of this disease are sometimes similar to those of ulcerative colitis, and several reports describe cases of diverticular colitis that progressed to typical ulcerative colitis. A 77-year-old woman with intramesenteric penetration of the sigmoid diverticulum underwent low anterior resection. One month later, the patient experienced anastomotic leakage, and transverse colostomy was performed...

REVIEW

Most common hepatobiliary manifestation of inflammatory bowel disease (IBD) are primary sclerosing cholangitis (PSC) and autoimmune hepatitis, ranking them as the main cause of liver transplantation (LT) in IBD setting. Course of pre-existing IBD after LT differs depending on many transplant related factors. Potential risk factors related to IBD deterioration after LT are tacrolimus-based immunosuppressive regimens, active IBD and cessation of 5-aminosalicylates at the time of LT. About 30% patients experience improvement of IBD after LT, while approximately the same percentage of patients worsens...

Lipomas of the sigmoid colon are rare entities. The present case describes a 27-year-old Caucasian woman who underwent a laparoscopic sigmoidectomy following the detection of a giant lipoma. The young patient was referred to the Emergency Department of the University Hospital of Heraklion (Crete, Greece) in May 2013 after experiencing intermittent abdominal cramping during defecation, and altering episodes of diarrhea and constipation. In addition, the patient described the protrusion of a solid tissue mass shaped like a 'champagne bottle cork' from the anus following defecation...

Colonic angiosarcoma is a rare malignancy representing only 0.0012% of all colorectal malignancies. Due to its non-specific symptoms, diagnosis is often delayed. However, because of the aggressive nature of this malignancy, it is important to keep it in the differential diagnosis of rectal bleeding, pelvic discomfort, chronic diarrhea, and weight loss in patients with risk factors. We present a case of angiosarcoma of the colon in a 74-year-old female with a remote history of chemo-radiation for anal squamous cell carcinoma (ASCC)...

A 67-year-old man with a slow-growing, asymptomatic perianal lesion was presented to the colorectal clinic. Physical examination and radiological investigation were suggestive of an externally prolapsing colonic polyp. However, intraoperative findings of a cystic lesion containing a thick brown substance questioned the initial diagnosis. After complete surgical resection of the encapsulated lesion, histological examination revealed a tailgut cyst (cystic hamartoma). These uncommon lesions originate from an embryological remnant of the hindgut...

BACKGROUND AND AIMS: Despite evidence that most nonmalignant colorectal polyps can be managed endoscopically, a substantial proportion of patients with a nonmalignant colorectal polyp are still sent to surgery. Risks associated with this surgery are not well characterized. We describe 30-day postoperative morbidity and mortality and explore risk factors for adverse events in patients undergoing surgical resection for nonmalignant colorectal polyps. METHODS: We analyzed data collected prospectively as part of the National Surgical Quality Improvement Program...

Background and Aims: The extent of lymph node harvesting during surgery for colorectal neoplasm [dysplasia and/or cancer] complicating inflammatory bowel disease [IBD] is a matter of debate. This study aimed to assess the risk of invasive rectal cancer in patients undergoing ileal pouch-anal anastomosis [IPAA] for colonic neoplasm complicating IBD, and thus to clarify whether a systematic total mesorectal excision [TME] should be systematically performed, or not, in those patients. Methods: From 1998 to 2015, all patients who underwent IPAA for colorectal neoplasm complicating IBD were included...

Mohamad Abdelaziz, Motaz Sayed
Laterally spreading tumors (LSTs) are generally defined as superficial lesions ≥10 mm in diameter that typically extend laterally rather than vertically along the colonic wall. Such lesions are now increasingly reported because of increased awareness and the introduction of chromo and magnifying colonoscopy. Although the clinicopathological characteristics and the efficacy of endoscopic management of LSTs have been defined in Japanese cohorts, reports from the Middle East are lacking where surgical resection is the mainstay of treatment...

BACKGROUND: Approximately 28% of patients with gastrointestinal (GI) cancers will receive targeted therapy (TT) because of the associated increases in survival. Only four studies have examined the symptom experience of these patients. To date, no studies have evaluated for differences in symptom occurrence, severity, and distress between patients who received chemotherapy (CTX) alone (n=304) or CTX with TT (n=93). METHODS: Patients completed self-report questionnaires, approximately one week after they received CTX...

143 Background: Managing physicians (medical oncologist, radiation oncologist, surgeons) have a responsibility to clinically stage patients prior to the initiation of cancer treatment. Clinical staging not only directs the treatment plan, but identifies appropriate clinical trials and estimates prognosis. We sought to determine whether engagement of managing physicians would result in increased clinical staging for various types of cancer. METHODS: Baseline data on clinical staging for breast, colorectal (colon, rectal, anal, rectosigmoid junction)*, thoracic (lung esophageal)†, genitourinary (prostate, penis, testes)‡, and pancreatic primary cancers were obtained...
