The occurrence of a fistula between the duodenum and the colon is very rare, although these two structures commonly lie in intimate relationship to each other. It is not uncommon for tumor of the right colon and proximal transverse colon to involve the duodenum by continuity, but fistulous connection between the duodenum and colon are infrequent In most of the reported malignant cases, the fistulas follow carcinomas of the transverse colon or the hepatic flexure of the colon. We report a rare case of malignant duodenocolic fistula which was first suspected by endoscopic examination and confirmed by operation.

When patients present with malignant cologastric fistulas, the tumor stage is often advanced and management is only palliative. We report the case of a 75-year-old man with a symptomatic cologastric fistula arising from an advanced tumor in the transverse colon, previously stented owing to malignant obstruction. An 8-cm-long covered self-expanding metal stent (COMVI enteral colonic stent; Taewoong Medical) was placed inside the primary stent, which sealed the fistula and completely alleviated the symptoms. Considering the successful outcome, we propose that insertion of a covered stent be considered in the palliative management of patients with malignant cologastric fistulas.

A colon lipoma is a remarkably rare tumor. In most cases, the tumors are asymptomatic and small in size, need to be differentiated from malignant tumors, and do not need any special treatment. Selection of the right surgical strategy depends on the status of bowel, as well as the size and the location of tumor. We encountered two patients with giant submucosal lipomas that had induced intussusceptions: one with a lipoma in the transverse colon and the other with a lipoma in the ascending colon. The diagnoses were made by using histological examinations. We report the clinical features, diagnoses, and treatments of, as well as our experience with, these two uncommon cases, and we present a review of the literature on this subject.

The association of congenital colonic atresia with imperforate anus is extremely rare. The authors were able to find only three case on our investigation of the English literature. We have recently managed a female infant with imperforate anus associated with atresia of the transverse colon.

Intestinal intussusception in adults is a rare disease. Most of the cases of adult intussusception are secondary to a definable lesion, and so surgical treatment generally needed. Intussusception that occurs after colonoscopic polypectomy is apparently a rare malady. A 77-year old man undergoing colonoscopic polypectomy was diagnosed as having colonic intussusception at the hepatic flexure. As there was no clinical improvement with conservative treatment, he underwent segmental resection of the ascending and transverse colon. Pathologic examination revealed that the colonoscopic polypectomy site was a leading point of the intussusception.

Percutaneous cecostomy is an uncommon procedure but is reported as an effective temporising measure to achieve acute decompression of bowel obstruction. It has been reported as a safe procedure in the setting of bowel obstruction providing relief of symptoms. The insertion of a cecostomy in the distal colon is not routinely advised as it will not allow passage of formed faeces. Cases of antegrade stenting of proximal colonic obstruction via cecostomy have been described; however, antegrade stenting of the distal colon from access in the ascending colon can be technically challenging. We describe a case of a percutaneous colostomy inserted temporally at the splenic flexure, which provided close access to an obstructing descending colonic tumour, allowing definitive management with placement of a colonic stent. This technical feasibility case provides evidence that a temporary cecostomy placed in the distal colon can be performed as a measure to facilitate definitive management.

It is well known that total colonoscopy is one of the essential procedure to make diagnosis of colonic and terminal ileal diseases, to detect early atage of colonic cancer and to do prophylactic removal of premalignant polyp. Previously commonly used longer colonoscope has been reached to ileocecal area with patients much discomfort arising from excessive loop formation at sigmoid or transverse colon because of no limitation of the length.

Anisakiasis refers to the infestation of humans by a species of marine nematode larvae belonging to the subfamily Anisakidae, and this condition is seen in people who eat inadequately prepared or raw salt-water fish and squid. Because Koreans like to eat raw fish, anisakiasis of the stomach has been reported occasionally, but involvement of the small bowel or colon is relatively rare. In the case of the colon, anisakiasis of the ascending colon or the transverse colon has been only infrequently reported, and the incidence of rectal anisakiasis is very rare. The present case is a 58-year-old man with no definite abdominal symptoms who visited our hospital for a medical checkup. A 2 cm sized whitish linear live larva was revealed in the rectum and it was removed by colonoscopy.

PURPOSE: The purpose of this study is to evaluate the clinical features that necessitate a temporary stoma for the treatment of colonoscopic perforations. RESULTS: Between January 2000 and July 2006, 30 patients were treated for colonoscopic perforation. Based on the perforation sites, we classified these patients into the following groups: proximal colon, sigmoid colon, and rectum; we then reviewed clinical data, including the time to operation and management. RESULTS: Seventeen patients had a perforation during the diagnostic colonoscopy. Of these patients, 14 patients had sigmoid colon perforation. Six underwent an operation within 10 hours after perforation. Of these six, four were managed by primary repair or resection with anastomosis, one sigmoid colon cancer patient by anterior resection, and one rectal cancer patient by low anterior resection with diverting ileostomy. Eight patients underwent more than 12 hours after perforation. Of these eight, three were managed by resection with anastomosis and diverting ileostomy and five by resection with end colostomy. Thirteen patients had a perforation during the therapeutic colonoscopy. Of these patients, 10 patients had a proximal colon perforation. Of these 10, 3 without fever or peritonitis symptom were managed by conservative management, 6 by primary repair or resection with anastomosis, and 1 transverse colon cancer patient by right hemicolectomy. Three patients had sigmoid colon perforation. Of these three, one was managed by primary repair, one by resection with anastomosis, and one sigmoid colon cancer patient by anterior resection. CONCLUSIONS: The mechanism of perforation, the site of the perforation, and the time to operation are associated with intraperitoneal contamination and have an influence on surgical treatment.

We report herein three cases of inflammatory myoglandular polyp (IMGP) presenting as hematochezia. The polyps had pedunculated, red, and smooth features, and were 12, 12, and 15 mm in diameter and located in the sigmoid colon, transverse colon, and rectum, respectively. Endoscopic polypectomies were performed. Histologic examination of the recovered specimens revealed inflammatory granulation in the lamina propria mucosa, proliferation of smooth muscle, and hyperplastic glands with cystic dilatation. The three colon polyps were finally diagnosed both clinically and histologically as IMGP. Endoscopists should bear in mind that a polyp featuring endoscopic findings of pedunculation or semipedunculation; a red, smooth, spherical, and hyperemic surface; and patchy mucosa exudation and erosion is likely to be an IMGP.
