Endoscopic Features of Postoperative Anastomotic Lesions in Patients with Crohn's Disease Compared with Right-side Colon Cancer: Are Anastomotic Linear Superficial Ulcers Recurrent in Crohn's Disease?

Objectives: Many patients have endoscopic evidence of recurrent Crohn's disease (CD) 1 year after intestinal resection, and endoscopic lesions predict future clinical recurrence. The aim of this study was to describe some anastomotic lesions including changes in endoscopic features in CD patients and to discuss recurrence. We also compared anastomotic lesions in CD patients and in right-side colon cancer (rt-CC) patients.

A detailed comparison between the endoscopic images using blue laser imaging and three-dimensional reconstructed pathological images of colonic lesions.

Blue laser/light imaging (BLI) is an image-enhanced endoscopy (IEE) technique that can provide an accurate diagnosis by closely observing the surface structure of various colonic lesions. However, complete correspondence between endoscopic images and pathological images has not been demonstrated. The aim of this study was to accurately compare endoscopic images and the pathological images using a three-dimensionally (3D) reconstructed pathological model.

Long-Term Survival After Pelvic Exenteration for Locally Recurrent Rectal Cancer Associated With Crohn's Disease With, Adjuvant Chemotherapy, and Immunosuppressive Therapy.

Crohn's disease (CD) is associated with an increased risk of developing colorectal cancer. In particular, cases in which long-term survival is achieved by patients with local recurrence of CD-associated rectal cancer are rare. We report a case in which curative resection was achieved for a 47-year-old man with long-standing CD and locally recurrent rectal cancer.

A 41-year-old man presented with abdominal fullness in late August 2012. Abdominal CT showed ileus caused by stenosis of the ileum and an enlargement of the ileocecal lymph nodes. Colonoscopy showed a steep elevated protruding tumor in the cecum, with multiple ulcerative lesions on top.

Intraluminal lavage to remove exfoliated tumor cells after colorectal endoscopic submucosal dissection.

Background: Endoscopic submucosal dissection (ESD) involves dissection of tumors and manipulation of them in an exposed condition for prolonged periods. A large number of tumor cells are exfoliated into the intestinal lumen after colorectal ESD. The aim of this study was to determine whether lavage volume has an influence on tumor cell clearance after colorectal ESD.

[A case of idiopathic portal vein obstruction identified by severe bleeding after a routine hemorrhoid operation].

We report our experiences of a case of repeated bleeding after hemorrhoid ligation. A 53-year-old man underwent hemorrhoid ligation for internal hemorrhoids at another hospital. Postoperatively, he developed severe and repeated bleeding.

Erythropoietin attenuates intestinal inflammation and promotes tissue regeneration.

Background: The prevalence of inflammatory bowel disease (IBD) is increasing. Since patients usually need long-term treatment and suffer from reduced quality of life, there is a need to develop new therapeutic strategy. The aim of this study was to investigate the therapeutic potential of erythropoietin (EPO) for the treatment of IBD.

Factors associated with treatment outcome, and long-term prognosis of patients with ulcerative colitis undergoing selective depletion of myeloid lineage leucocytes: a prospective multicenter study.

Background: Patients with ulcerative colitis (UC) have elevated/activated myeloid lineage leucocytes and may respond favorably to adsorptive granulocyte/monocyte apheresis (GMA). However, there are patients who respond well to GMA, and patients who do not benefit. Therefore, predictive factors of GMA efficacy need to be defined.

Visualization of Lymph/Blood Flow in Laparoscopic Colorectal Cancer Surgery by ICG Fluorescence Imaging (Lap-IGFI).

Purpose: In laparoscopic colorectal cancer (Lap-CRC) surgery, determination of a suitable mesentery division line and the appropriate degree of lymphadenectomy by tracing the blood supply is critical. We performed visualization of the lymph and blood flow by laparoscopic indocyanine green (ICG) fluorescence imaging (Lap-IGFI).

Methods: ICG is injected into the submucosa near the tumor via colonoscopy, and the lymph flow is observed.

HVEM expression contributes to tumor progression and prognosis in human colorectal cancer.

Background: Herpesvirus entry mediator (HVEM) has been recently suggested to play certain roles in cancer biology. We examined HVEM expression in human colorectal cancer (CRC) to reveal its clinical importance.

Materials And Methods: Immunohistochemical staining was carried-out in normal epithelium, benign and malignant lesions.

Mucinous adenocarcinoma associated with a chronic perianal fistula - a review of cases from a single institution.

Purpose: The purpose of this study was to evaluate the clinicopathological features of mucinous adenocarcinoma associated with perianal fistulas (MAF), to assess the importance of preoperative MRI analysis, and to determine the optimal surgery.

Methods: We performed a retrospective analysis of the data from seven patients with MAF treated at our hospital between 2000 and 2013, and herein discuss the importance of preoperative magnetic resonance imaging (MRI) and of radical surgery.

Results: The male to female ratio was 5:2, and the mean age of the patients was 63 years old (28-70).

The authors present a case of rectal carcinoid tumor with lateral lymph node metastases and liver metastases that was successfully treated by 4 resections. A 70-year-old man was diagnosed with a rectal carcinoid tumor (20 mm in diameter) with submucosal (SM) invasion. Radical resection was performed at 25 months, 38 months, and 57 months, when abdominal computed tomography (CT) revealed metachronous liver metastases of the rectal carcinoid tumor.

Prophylactic laparoscopic lateral pelvic lymph node dissection for lower rectal cancer: remarking on the vesicohypogastric fascia.

Objective: To introduce the prophylactic laparoscopic lateral pelvic lymph node dissection performing by remarking the vesicohypogastric fascia following total mesorectal excision for patients with advanced lower rectal cancer without radiological evidence of lymph node involvement.

Surgical Method: We set 5 ports for conventional laparoscopic rectal surgery. During the prophylactic laparoscopic lateral pelvic lymph node dissection, we retrieved the lymph nodes from the internal iliac area and obturator area.

Laparoscopic surgery after endoscopic resection for rectal cancer and neuroendocrine tumors.

Background: Endoscopic resection (ER) of tumors causes inflammation, edema, fibrosis, and adhesions in the surrounding tissue. However, little is known about the effect of ER on subsequent laparoscopic surgery for rectal tumors. The objective of this retrospective study was to analyze the effect of ER on subsequent laparoscopic surgery for rectal tumors.

Exfoliated Tumor Cells in Intraluminal Lavage Samples after Colorectal Endoscopic Submucosal Dissection: A Pilot Study.

Endoscopic submucosal dissection involves dissecting manipulation performed with tumors in an exposed condition for a long period of time. Thus, there is a risk for implantation of tumor cells. The objectives of this study were to examine exfoliated tumor cells after colorectal endoscopic submucosal dissection and to elucidate the effectiveness of intraluminal lavage to remove these cells.

Local recurrence after rectal endoscopic submucosal dissection: a case of tumor cell implantation.

We report a case of local recurrence of cancer after rectal endoscopic submucosal dissection (ESD). A 52-year-old male underwent a curative resection with ESD for rectal intramucosal cancer. Seventy-four months after ESD, surveillance colonoscopy showed an elevated lesion on the ESD scar, suspicious of a recurrence.

Clinical outcomes of pelvic exenteration for locally advanced primary or recurrent non-colorectal pelvic malignancies.

Objective: The aim of this study was to evaluate the outcomes of patients who underwent extensive pelvic surgery for locally advanced primary or recurrent non-colorectal pelvic malignancies.

Patients And Methods: We performed a retrospective review of the medical records of 19 patients with non-colorectal pelvic malignancies who underwent extensive surgery at our institution between January 2005 and May 2013. Overall survival and progression-free survival were estimated using the Kaplan-Meier method and compared using the logrank test.

The "sliding door" technique for closure of abdominal wall defects after rectus abdominis musculocutaneous flap transposition.

Radical surgery is often necessary in patients with local recurrence of rectal cancer or in those with carcinoma associated with an anal fistula. The surgery may include extended excision of the perineal area and can create a large dead space in the pelvis and a large skin defect, often necessitating reconstruction of the pelvic floor using rectus abdominis musculocutaneous (RAM) flap transposition. Wound dehiscence and incisional hernia are common complications of RAM flap transposition.
