BACKGROUND AND STUDY AIM:  The role of colorectal endoscopic submucosal dissection (ESD) is standardized in Japan and East Asia, but technical difficulties hinder its diffusion. The aim was to identify predictors of difficulty for each neoplasm type. METHODS:  A competent operator performed all procedures. ESD difficulty was defined as: en bloc with a slow speed (< 0.07 cm (2) /min; 30 × 30 mm neoplasm in > 90 min), conversion to endoscopic mucosal resection, or resection abandonment...

PURPOSE: Transanal minimally invasive surgery (TAMIS) is gaining worldwide popularity as an alternative for the transanal endoscopic microsurgery (TEMS) method for the local excision of rectal polyps and selected neoplasms. Data on patient reported outcomes regarding short-term follow-up are scarce; data on functional outcomes for long-term follow-up is non-existent. METHODS: We used the fecal incontinence severity index (FISI) to prospectively assess the fecal continence on the intermediate-term follow-up after TAMIS...

Transanal endoscopic microsurgery (TEM) is currently the only one-port system in endoscopic surgery, which a direct endoluminal approach can lead to the target organ through a natural opening of human body. TEM has been applied in colorectal surgery for over 3 decades. Compared with radical surgery, TEM has the advantages, such as quicker recovery, shorter hospital stay and fewer complications. One perfect TEM surgical system, which mainly consists of three parts, namely peculiar rectoscope for surgery, special surgical instruments and imaging system, is the foundation of standardized development of TEM...

Biological tissues often experience drastic changes in their microstructure due to their pathophysiological conditions. Such microstructural changes could result in variations in mechanical properties, which can be used in diagnosing or monitoring a wide range of diseases, most notably cancer. This paves the avenue for non-invasive diagnosis by instrumented palpation although challenges remain in quantitatively assessing the amount of diseased tissue by means of mechanical characterization. This paper presents a framework for tissue diagnosis using a quantitative and efficient estimation of the fractions of cancerous and non-cancerous tissue without a priori knowledge of tissue microstructure...

BACKGROUND AND AIMS: Minimally invasive techniques are available to safely and efficaciously remove even the largest rectal polyps. This study aimed to investigate the magnitude of cases still referred for radical rectal surgery, the reasons for theses referrals, and to perform a re-evaluation of cases potentially suitable for endoscopic therapy. METHODS: A retrospective analysis of data from the Dutch Pathology Registry (PALGA) was performed using the records of patients who underwent major surgical treatment for a histologically proven benign rectal polyp between 2005 to 2014 in the Netherlands...

EDITORIAL

Attenuated adenomatous polyposis (AAP) is a poorly understood syndrome, that can be defined as the presence of 10-99 synchronous adenomas in the large bowel, and it is considered a phenotypic variant of familial adenomatous polyposis (FAP). This definition has the advantage of simplicity, but it may include sporadic multiple adenomas of the large bowel at an extreme, or FAP cases on the other side. AAP shows a milder phenotype than FAP, with an older age of onset of adenomas and cancer, and less frequent extracolonic manifestations...

AIM: To compare high definition white light endoscopy and bright narrow band imaging for colon polyps' detection rates. METHODS: Patients were randomised to high definition white light endoscopy (HD-WLE) or the bright narrow band imaging (bNBI) during withdrawal of the colonoscope. Polyps identified in either mode were characterised using bNBI with dual focus (bNBI-DF) according to the Sano's classification. The primary outcome was to compare adenoma detection rates (ADRs) between the two arms...

We investigated the feasibility of using ultrasound colonography (USC) to visualize the healthy colon and rectum and detect colorectal polyps. Eight healthy volunteers underwent USC after standard bowel preparation. The feasibility and image quality of USC in different segments were evaluated. Then, USC was conducted on eight patients with known colonic neoplasms using colonoscopy as the reference standard. For volunteers, USC examinations were successfully performed on four (50.0%) ascending, three (37.5%) transverse and eight (100%) descending colons, as well as all sigmoid colons and rectums...

Peutz-Jeghers syndrome (PJS) is an autosomal dominant hamartomatous polyposis of the gastrointestinal tract, with pigmentation around lips, the buccal mucosa, and anal area. Patients have a strong family history. Patients of PJS present with abdominal pain, blood in stools, and occasionally melena because of polyps, along with classical mucocutaneous pigmentation. Very rarely a sporadic case of Peutz-Jeghers syndrome occurs in early childhood and adolescent. The case of a 14-year boy is reported, who presented with intussussception and bleeding per rectum due to jejunal polyp and a rectal polyp...

INTRODUCTION: Transanal endoscopic microsurgery (TEM) was developed as a less aggressive alternative treatment for rectal lesions (mainly adenomas and adenocarcinomas). However, its use for other rectal lesions has become more frequent, trying to reduce the morbidity associated with more invasive techniques. The aim of this study is to describe our experience in the use of TEM in other rectal lesions. METHODS: Retrospective and descriptive study including patients operated with TEM (from June 2008 to December 2016) for the treatment of rectal lesions different from adenomas or adenocarcinomas...

AIM: Transanal minimal invasive surgery has been practiced for several years for excision of rectal tumors however there is no standard consensus about its applications. This minimally invasive approach helps in avoiding major rectal resections and its associated risk of mortality and morbidity.The aim of this study is to describe a single center experience with transanal glove port excision of rectal tumors which are not amenable to colonoscopic excision. MATERIALS AND METHODS: Between the years 2011 and 2014, 9 patients underwent glove port excision of rectal tumors located within 15 cm from the anal verge...

Radiation-associated colon cancer is a rare clinical entity. We herein describe the case of a patient with radiation-associated colon cancer who had undergone low anterior resection for rectal cancer following preoperative radiotherapy. Certain characteristics of radiation-associated colon cancer are highlighted. The patient was a 48-year-old man who had undergone low anterior resection for rectal cancer following preoperative radiotherapy at a total dose of 50 Gy, at the age of 29 years. When the patient presented at the University of Tokyo Hospital, 19 years after the surgery, he complained of severe anal pain and frequent defecation...

BACKGROUND: It is often stated that if a patient presents with 'painless rectal bleeding' then a rectal polyp is the probable diagnosis. The aim of this study is to review our experience of children undergoing endoscopy to assess if the above statement is correct. METHODS: The senior author keeps a prospective database of every child undergoing flexible sigmoidoscopy or colonoscopy. As part of this database, the symptoms and signs that the patient presents with, specifically abdominal pain, diarrhoea, mucous per rectum and rectal bleeding, are recorded...

REVIEW
Mark J Pidala, Marianne V Cusick
Difficult colorectal polyps represent lesions that pose a challenge to traditional endoscopic snare polypectomy. These polyps have historically been managed by surgical resection. Currently, several less invasive options are available to avoid colectomy. Repeat colonoscopy and snare polypectomy by an expert endoscopist, endoscopic mucosal resection, endoscopic submucosal dissection, and combined endoscopic and laparoscopic surgery have been developed to remove difficult polyps without the need for formal surgical resection...

CASE SUMMARY: A 17-year-old female neutered domestic shorthair cat presented for several days of reduced faecal volume and a rectal prolapse. Physical examination revealed a 2 cm rectal prolapse, hepatomegaly and a low body condition score of 3/9. Haematology and biochemistry revealed a mild non-regenerative anaemia (haematocrit 24.5%; reference interval [RI] 30.3-52.3%), a mild mature neutrophilia (16.21 × 10(9)/l; RI 1.48-10.29 × 10(9)/l) and a mild increase in alanine aminotransferase activity (222 IU/l; RI 12-130 IU/l)...

Anorectal melanoma is a rare disorder. There have only been a few cases reported and there is no consensus of treatment. We report a case of 50-year-old Caucasian man presenting intermittent prolapse of an anorectal mass during 6 months with occasional bleeding. Biopsies came up with the diagnosis of malignant melanoma. No distant metastases were found. He underwent an abdominoperineal resection due to internal sphincter invasion. A second tumour was diagnosed in final histologic examination: a dysplastic rectal polyp invaded by the melanoma (collision tumour)...

We describe a highly unusual case of solitary rectal ulcer syndrome (SRUS) that presented as a large polyp protruding from the anal canal. A 67-year-old man presented with rectal bleeding and mucus discharge. At examination under anaesthesia, a large pedunculated polypoidal lesion was found, measuring 25 × 20 mm, arising posterolaterally from the anorectal junction and protruding externally 50 mm in size. SRUS can be a misnomer as the condition can present in a number of different ways and only a minority of patients has a solitary ulcer...
