In Japan, colorectal endoscopic submucosal dissection (ESD) is being conducted safely and effectively as shown by the increased number of the cases, however, it is still regarded as a complicated and challenging procedure. Therefore, piecemeal endoscopic mucosal resection (p-EMR) is still regarded as an appropriate treatment, rather than ESD for large colorectal tumors, especially in Western countries. Areas covered: There are several factors that are responsible for colorectal ESD difficulty. Firstly, there is no adequate traction or counter-traction in colorectal ESD...

BACKGROUND AND AIMS: Early esophageal squamous cell neoplasia (ESCN) can be successfully treated by endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), or radiofrequency ablation (RFA). A new portable, battery-powered cryotherapy system using nitrous oxide (cryoballoon focal ablation system (CbFAS) has been used for Barrett's esophagus. It consists of a small hand-held device containing liquid nitrous oxide, which converts to gas within a low-pressure-compliant through-the-scope balloon and freezes targeted mucosa in contact with the balloon...

Intestinal tuft cells are one of 4 secretory cell linages in the small intestine and the source of IL-25, a critical initiator of the type 2 immune response to parasite infection. When Raptor, a critical scaffold protein for mammalian target of rapamycin complex 1 (mTORC1), was acutely deleted in intestinal epithelium via Tamoxifen injection in Tritrichomonas muris (Tm) infected mice, tuft cells, IL-25 in epithelium and IL-13 in the mesenchyme were significantly reduced, but Tm burden was not affected. When Tm infected mice were treated with rapamycin, DCLK1 and IL-25 expression in enterocytes and IL-13 expression in mesenchyme were diminished...

BACKGROUND AND AIMS: Endoscopic resection of extensive esophageal lesions has become more common as endoscopic resection techniques and equipment has developed. However, extensive esophageal endoscopic resections can cause postoperative esophageal strictures, which have a negative impact on the quality of life of patients. We aimed to review current treatments and innovative approaches to prevent esophageal strictures after widespread endoscopic resection of esophageal lesions. METHODS: We performed a comprehensive literature search using predetermined search terms from 2000 to 2016 to identify relevant articles and summarized their results as a narrative review...

Cancer invasion of the lamina propria is an important pathological finding. However, the clinicopathologic features and diagnostic accuracy of intramucosal carcinoma assessment in colorectal carcinoma (CRC) are unknown. In this study, intramucosal CRCs were reviewed in institutions affiliated with the Japanese Society for Cancer of the Colon and Rectum, and 32 cases with invasion of the lamina propria were identified. Next, a consensus meeting was held to select cases with a high consensus about the presence of invasion, which were reviewed by one Western pathologist for confirmation...

PURPOSE OF REVIEW: Most of small tumours in gastrointestinal tract are easily removed by endoscopic mucosal resection (EMR). However, EMR are sometimes not reliable to ensure the complete resection for large tumours. Although endoscopic submucosal dissection (ESD) was developed, it had a higher risk for complications such as perforation and bleeding. The techniques and clinical outcomes of EMR and ESD are reviewed. RECENT FINDINGS: ESD is more effective for early gastric and oesophageal cancer with higher en-bloc resection rate and lower local recurrence in comparison to EMR...

INTRODUCTION: Primary anorectal malignant melanoma is a rare and aggressive tumor that carries a poor prognosis. Anorectal melanoma (ARM) is often misdiagnosed as hemorrhoids adenocarcinoma polips and rectal cancer. ARM spreads along sub-mucosal planes and is often to wide-spread for complete resection at time of diagnosis and almost all patients die because of metastases. PRESENTATION OF THE CASE: A 77-year-old male patient presented a history of recurrent rectal bleeding and whose histopathological diagnosis was melanoma...

Resection of buccal mucosa tumors may occasionally involve the labial angle and peripheral skin. Reconstruction is required when the resection involves more than one-third of the lip. We describe a single-stage reconstruction using a facial artery musculomucosal (FAMM) flap and a vermilion advancement flap after buccal mucosa resection including the labial angle. A 62-year-old woman with carcinoma in situ of the buccal mucosa underwent tumor resection. The resection included the right labial angle and peripheral skin...

BACKGROUND: The rectum is a relatively uncommon site for lymphoma compared with other gastrointestinal sites; no consensus regarding management of primary rectal lymphoma (PRL) has been formed due to its limited frequency. We aimed to investigate clinical characteristics and treatment outcomes in patients with PRL in a single center patient cohort. METHODS: We retrospectively analyzed the results of 16 consecutive patients with PRL, identified and treated at the Asan Medical Center, Seoul, Korea between January 1993 and December 2014...

Meckel's diverticulum (MD) is the most common gastro-intestinal congenital malformation (approximately 2% in the overall population). The lifetime risk of related complications is estimated at 4%. These include gastro-intestinal bleeding, obstruction or diverticular inflammation. Diagnosis is difficult and rarely made, and imaging, especially in the case of complicated disease, is often not helpful; however exploratory laparoscopy is an important diagnostic tool. The probability of onset of complication decreases with age, and the diagnosis of MD in the adult is therefore often incidental...

The multi-step progression of colorectal cancer through precancerous lesions (adenoma and dysplasia) is associated with cumulative molecular alterations, a number of which have also been demonstrated to be present in morphologically normal transitional mucosa adjacent to colorectal cancer. The cytoskeletal protein cytokeratin 7 (CK7) and the receptor tyrosine kinase, KIT proto-oncogene receptor tyrosine kinase (CD117), encoded by the proto-oncogene c-Kit, are lacking in normal colorectal crypt epithelium and are aberrantly expressed in a subset of colorectal cancer...

A 65-year-old man presented with bloody stool. Colonoscopy revealed a raised tumor in the rectum, above the peritoneal reflection. He underwent endoscopic mucosal resection, but the pathological findings suggested the possibility of residual cancer. We performed laparoscopic low anterior resection using a circular stapling instrument for additional curative surgery. However, we could not insert the shaft of the endoscopic circular stapler from the anus because of anal stenosis due to Whitehead's hemorrhoidectomy the patient had undergone 20 years earlier...

REVIEW
Richard B Cannon, Jeffrey J Houlton, Eduardo Mendez, Neal D Futran
Head and neck cancer surgery is often a complex multi-step procedure that includes major resections, vascularised tissue reconstruction, and extensive neck dissection. The upper aerodigestive tract mucosal lining is often disrupted during surgery, which requires the management of a clean-contaminated field and the need to reconstruct the mucosal lining. With bacterial contamination, surgical site infections (SSI) are a serious complication that can result in delayed wound healing, wound breakdown, fistula formation, and compromised tissue reconstruction...

Gustavo Maluf, Rogério Jardim Caldas, Paulo Sérgio Silva Santos
Lesions associated with medication-related osteonecrosis of the jaws (MRONJ) are refractory to different treatment approaches. Hence, auxiliary approaches capable of improving patient outcomes should be explored. Leukocyte- and platelet-rich fibrin (LPRF) is a second-generation platelet concentrate (natural autologous fibrin matrix). It shows anti-infectious activity through immune regulation and accelerates the angiogenesis and multiplication of fibroblasts and osteoblasts; in consequence, it stimulates soft tissue healing and prevents exposure of the alveolar bone in the oral cavity...

OBJECTIVES: In Western countries ESD (Endoscopic Submucosal Dissection) has not prevailed due to training issues and a target patient population. We reported a hybrid ESD technique, SEMR (submucosal endoscopy with mucosal resection), in which the submucosal dissection is performed chiefly by blunt balloon dissection. We have reported successful application in the porcine colon. In this study we compared the safety and efficacy between SEMR with ESD in the porcine esophagus and stomach...
