Background: Interval colorectal cancer (CRC) accounts for 3% to 8% of all cases of CRC in the United States. Data on interval CRC by race/ethnicity are scant. Objective: To examine whether risk for interval CRC among Medicare patients differs by race/ethnicity and whether this potential variation is accounted for by differences in the quality of colonoscopy, as measured by physicians' polyp detection rate (PDR). Design: Population-based cohort study...

BACKGROUND: The risks of minor adverse events (MAEs) such as abdominal pain and bloating after colon polypectomy (CP) are less clearly documented than major adverse events. However, these complications may cause significant discomfort during the performance of normal activities. We aimed to estimate the incidence of MAE, associated risk factors, and healthcare resource utilization after CP. METHODS: Patients who underwent CP were prospectively enrolled in this study...

Polyps of the lower reproductive tract are found in 7.8-50% of women. It has been hypothesized that cytogenetic modifications on chromosomes 6, 7 and 12 as well as epigenetic factors involving enzyme and metabolic activities may cause polyps to develop. Cervical polyps found in 2-5% of cases are of low clinical significance and can cause, although rarely, post coital bleedings. Cervical polyps grow during pregnancy and mucorrhoea. Trans vaginal ultrasound (TVU) provides an excellent diagnostic technique to diagnose the size and the anatomic location of endometrial polyps (EPs)...

BACKGROUND: Removal of adenomas reduces colorectal cancer incidence and mortality; however, the benefit of surveillance colonoscopy on colorectal cancer risk remains unclear. We examined heterogeneity in colorectal cancer incidence in intermediate-risk patients and the effect of surveillance on colorectal cancer incidence. METHODS: We did this retrospective, multicentre, cohort study using routine lower gastrointestinal endoscopy and pathology data from patients who, after baseline colonoscopy and polypectomy, were diagnosed with intermediate-risk adenomas mostly (>99%) between Jan 1, 1990, and Dec 31, 2010, at 17 hospitals in the UK...

RATIONALE: Peutz-Jeghers syndrome (PJS) is an autosomal dominant genetic syndrome characterized by a unique type of gastrointestinal hamartomatous polyp associated with oral and anal mucocutaneous pigmentations. Peutz-Jeghers polyps occur most numerously in the small intestine but frequently in the colon and stomach, only a few cases have been reported in the duodenum. PATIENT CONCERN: A further family history survey discovered 10 out of 14 members of the family (in 4 generations) had mucocutaneous pigmentations, but many of them were living in rural areas where they had no access to specialized medical services, so none were checked with endoscopy for polyps of hamartoma...

BACKGROUND/PURPOSE: Interval colorectal cancer (CRC) is an emerging issue in CRC screening and surveillance. The frequency of interval CRC and its associated factors have not been well studied in Eastern Asia. We aim to clarify the factors associated with interval CRC. METHODS: CRC patients who had negative colonoscopy results 6-36 months prior to cancer diagnosis were defined as cases of interval CRC. Patient characteristics, past history, colon preparation, colonoscopy findings, and pathology were retrospectively evaluated...

Combined endoscopic laparoscopic surgery (CELS) is a novel technique for resection of benign colon polyps, which are not amenable for endoscopic resection. A review of ten studies including 416 patients shows that polyps were successfully resected in 65-97% of the patients. Polyp recurrence after CELS is low, and the frequency of adenocarcinoma is comparable with the frequency in large polyps (> 2 cm) resected endoscopically. CELS can be performed for a variety of indications but should be done after renewed endoscopy...

Colonoscopy is the standard of care for screening and surveillance of colorectal cancers. Removal of adenomatous polyps prevents the transformation of adenomas to potential adenocarcinoma. While most polyps are amenable to simple endoscopic polypectomy, difficult polyps that are large, broad-based, or located in haustral folds or in tortuous colon segments can present a challenge for endoscopists. Traditionally, patients with endoscopically unresectable polyps have been referred for oncologic surgical resection due to the underlying risk of malignancy within the polyp; however, the majority of these polyps are benign on final pathology...

INTRODUCTION: Intestinal malrotation is a congenital abnormality which occurs due to a failure of the normal 270° rotation of the midgut. The non-rotation type is usually asymptomatic and discovered incidentally on imaging studies. Intestinal malrotation accompanied by colon cancer is extremely rare. PRESENTATION OF CASE: A 53-year-old male presented with postprandial abdominal discomfort. Colonoscopy showed a 14mm polyp in the sigmoid colon and endoscopic polypectomy was performed...

Background and study aims Colonic polyps > 1 cm in size are commonly managed using hot polypectomy techniques. The most frequent adverse events (delayed bleeding, post-polypectomy syndrome, and perforation) are related to electrocautery-induced injury. We hypothesized that cold resection of large polyps may have similar efficacy and improved safety compared to hot polypectomy. Our aims were to evaluate efficacy and safety of piecemeal cold snare resection of colonic polyps > 1 cm. Patients and methods Patients undergoing lift and piecemeal cold snare polypectomy of non-pedunculated colon polyps > 1 cm from October 2013 to September 2015 were identified retrospectively...

A man aged 65 years presented with symptomatic anaemia without overt gastrointestinal bleeding. An oesophagogastroduodenoscopy (EGD) was performed and he was found to have a large ulcerated pedunculated Brunner's gland hamartoma in the duodenal bulb. The polyp was resected using snare cautery in forward and retroflexed positions. Colonoscopy was also performed and a few diminutive polyps were resected. A year later, the patient returned for a surveillance EGD, and no residual polyp was noted. Haemoglobin and iron studies normalised within a few months after polypectomy, with resolution of symptoms...

A colonic arteriovenous malformation (AVM) is a significant vascular lesion of the gastrointestinal tract and a common cause of lower gastrointestinal bleeding. AVMs are usually identified endoscopically as bright red, flat lesions. AVMs with a polypoid appearance are extremely rare in the large intestine. We present two cases of colonic polypoid AVM, which were detected incidentally during screening colonoscopy. Both the patients had no history of gastrointestinal bleeding such as melena or hematochezia. Colonoscopy revealed pedunculated polyps overlaid by hyperemic mucosa in the ascending colon and proximal sigmoid colon...

A 64-year-old woman underwent polypectomy for a rectal polyp(Isp). Pathological findings were invasion of the submucosa( 3,500 mm diameter), and she underwent anterior resection for rectal cancer(RS, pT1b, pN0, cM0, Stage I )without adjuvant chemotherapy. Lung masses were found in her right(8mm)and left lung(7mm). The tumors enlarged during the 4 month follow-up period. We decided to perform left partial pneumonectomy. The tumor was diagnosed as a lung metastasis from colon cancer by pathology. Because the right tumor was located towards the center, performing right pneumonectomy would have been quite invasive and we feared occult metastases...

We report a 27-year-old female who was diagnosed with adenocarcinoma of the uterine cervix associated with Peutz- Jeghers syndrome(PJS). She had undergone 5 surgeries for intestinal intussusception and had been diagnosed with PJS. She was referred to our hospital, complaining of watery vaginal discharge, and was diagnosed with adenocarcinoma of the uterine cervix. Following neoadjuvant chemotherapy, radical hysterectomy and small intestinal polypectomy by intraoperative endoscopy were performed. Among the third-degree relatives of her family, 10 had been diagnosed with PJS; of these 10, uterine cervical adenocarcinoma occurred in 3 relatives, pancreatic cancer in 2, cholangiocellular carcinoma in 1, and colon cancer in 1...

Colonoscopy, either performed as screening or as a therapeutic proceedure, is, in general, very safe with only a few cases of serious complications. Most cases of bleeding after endoscopic polypectomy can be safely managed endoscopically. The rare cases of colonic perforations still have to be managed by surgical intervention. The postpolypectomy-coagulation syndrome and a cecal volvulus are very rare complicatoions after colonoscopy. In the current manuscript, we describe a rare case of a cecal volvulus after routine colonoscopy due to an unknown mobile coecum as a predisposition...
