the opacities were tablets trapped in the right colon by a neoplastic stricture (Fig. 2). At laparotomy a tumour was found encircling and obstructing the colon 12 cm above the ileocaecal valve. A right hemicolectomy was performed. The tumour was 8 cm long and was invading but not perforating the muscle coat. The lymph nodes were not involved. Several of the tablets were enmeshed in the papillae of

We present a case report of a patient with imaging findings of right colon diverticulitis that mimics colon cancer. The computed tomography showed a segment of narrowing with shoulder formation at ascending colon suggesting cancer. The colonoscopy and the follow-up imaging clarify the diagnosis of diverticulitis. We assess the value of computed tomography findings of acute diverticulitis in exc...

although splenic metastasis is fairly common in disseminated cancer, solitary splenic metastasis in the absence of diffuse dissemination is rare. we report a case of 44 year-old man who developed isolated splenic metastasis of colon cancer. the patient had undergone right sided hemicolectomy for colon cancer in 1988. in 2001, he underwent reoperation because of local recurrence of tumor in the ...

from june 1989, to june 1991, 58 patients with gi polyps were reviewed. except two patients who had multiple polyps, 56 had only one polyp. the size of polyps were 0.5 to 3 em in diameter. 51 (75%) of polyps were located in the rectosigmoid region, 25 (37%) were in the rectum and 26 (38%) in the sigmoid. (seventeen) (25%) polyps (two in right colon, four in transverse, and 11 in descending colo...

BACKGROUND Although colonoscopy is the criterion standard for detecting colorectal adenomas and cancers, a significant percentage of adenomas are missed. OBJECTIVE To compare forward-viewing with ultrawide-viewing colonoscopy in the detection of simulated colon polyps in an in vitro colon model. DESIGN Prospective, multicenter. SETTING Six endoscopy units (3 in the United States and 3 in ...

BACKGROUND Laparoscopically-assisted right hemicolectomy (LRH) is an acceptable alternative to open surgery for right-sided colon cancer which offers patients less pain and faster recovery. However, special equipment and substantial surgical experience are required. The aim of the study is to compare the short-term surgical outcomes of LRH and open right hemicolectomy through right transverse s...

BACKGROUND Alterations in epithelial proliferation and apoptosis in colonic mucosa are associated with an increased risk of colon cancer. It is unclear if these alterations represent a generalised "field defect". AIMS To analyse segmental patterns of cell proliferation and apoptosis in the colon of subjects with a high and no apparent risk of colon cancer. METHODS Pancolonoscopy was perform...

Methods The study group is yet represented by 33 patients: 17 males and 16 females (median age 76, range 70–89). The location of cancer was respectively: 5 (15, 15%) in the rectum, 15 (45, 45%) in the left colon, 11 (33, 33%) in the right colon, 1 (3, 3%) in the transverse colon, 1 (3, 3%) synchronous in the caecum and the sigmoid colon. The associated diseases observed were: chronic obstructiv...

Colorectal cancer is extremely rare in children. We report a case of a 12-year-old boy who presented with a five-month history of weight loss and anorexia, associated with vomiting episodes, dizziness, fatigue, and dyspnea. On physical examination, a palpable abdominal mass was noticed on the right hypochondrium and flank. An imaging study was performed, which showed a solid mass on the right c...

Schwannoma, (also called neurilemoma, neurinoma) is a benign tumor originating from nerve sheath of the Schwann cells. They rarely occur in gastrointestinal tract. We report a rare case of colonic schwannoma in a 38-year-old woman presenting with worsening right-sided pelvic pain, discovered after laparoscopic right-colon resection performed after the detection of a atypical polypoid mass in th...
