1/21. life-threatening gastrointestinal hemorrhage due to juvenile polyposis.

    A 14-yr-old, previously healthy boy presented with massive lower GI hemorrhage. After the routine endoscopic and radiological evaluation, laparotomy and intraoperative colonoscopy revealed multiple polyps in the colon. A hemicolectomy was performed because of the severity of hemorrhage. A diagnosis of juvenile polyposis was made based upon histological findings and the family history. This is an extremely unusual presentation of juvenile polyposis and has been reported only once before. The clinical features, diagnosis, and therapeutic options for juvenile polyposis are discussed. Juvenile polyposis, although a rare condition in the pediatric population, should be considered in the differential diagnosis of life-threatening GI hemorrhage.

2/21. Laparoscopic management of colonoscopic perforations.

    Colonic perforation is a dangerous complication of colonoscopy, both diagnostic and therapeutic, and its management has become controversial. The question of conservative vs operative treatment is still under debate. Despite the recent expansion and wide acceptance of laparoscopy by surgeons, the feasibility of this technique as a means of treating abdominal emergencies has also been questioned. Of 575 patients admitted to our institution for abdominal emergencies between 1993 and 1998, 365 were treated via a laparoscopic approach. Two of these patients were treated for colonoscopic perforations, one after a diagnostic procedure and one after an operative procedure. Our technique employs an open umbilical approach with two other trocars introduced in the right iliac fossa and left flank. In the first case, a diverticular perforation of the subperitoneal rectum was suspected. The abdomen was copiously irrigated with saline solution and a drain was left in the pelvis. In the second patient, localized peritonitis was found in the left iliac fossa due to a microperforation of the sigmoid colon. It was repaired with a single absorbable suture. The postoperative course was unremarkable in both cases. In patients with an emergency abdomen due to a postcolonoscopy perforation, we consider the laparoscopic approach feasible and safe in experienced hands. It allowed us to avoid an unnecessary laparotomy and other time-consuming and expensive diagnostic investigations. This approach represents an excellent means of managing this type of emergency abdominal situation.

3/21. Laparoscopic-assisted coloscopic polypectomy.

    PURPOSE: patients with colorectal polyps often display a large kink or distinct mucosal fold in the area where the polypectomy is to take place. As a result, there is a higher risk of perforation or partial ablation during an endoscopic polypectomy. Is it safer to perform an endoscopic polypectomy using the control and assistance of a laparoscope? Can a segment resection of the colon that would otherwise be necessary be avoided? methods: An endoscopic polypectomy using a laparoscope was conducted on six patients whose colorectal polyps were in an anatomically unfavorable location. The need for an open or laparoscopic segment resection or colotomy was indicated in all cases. The growth was located in the rectosigmoidal transition in five patients and in the region of the left flexure in one patient. We decided that an endoscopic polypectomy using the assistance of a laparoscope would be the most comfortable and technically elegant method, as well as easy. Except the well-known risks of laparoscopy and endoscopic polypectomy, no other risks have been seen in our patients. The affected area of the colon, the sigma, and the left flexure were mobilized and stretched as much as possible to enable a simultaneous and low-risk endoscopic polypectomy. In one case, we had to conduct a fractionated ablation because of a very wide-based finding. RESULTS: The operation averaged 57 minutes, and no operation-specific complications were observed. Postoperative recovery in the hospital was very short and averaged 2.5 days. The histopathologic findings were benign in all cases, but a serious dysplasia was diagnosed in one patient. CONCLUSIONS: The laparoscopic-assisted polypectomy is a safe method to remove even complicated polyps in anatomically unfavorable locations.

4/21. Giant inflammatory polyposis of the descending colon associated with a Crohn's disease-like colitis.

    A case of giant inflammatory polyposis associated with a localized inflammatory bowel disease of the descending colon in a 49-year-old man is presented. Lower abdominal distension rapidly appeared without any previous history of gastrointestinal disease. Two months later, he underwent a left hemicolectomy. Postoperative recovery was complete and he remains in good health more than 2 years later. The resected colon showed a giant and bizarre polyposis measuring up to 12 cm in length and 2 cm in height and covering the entire circumference of the colon. The polyposis consisted of narrow worm- or noodle-like polyps that bridged over the irregularly shaped ulcers, which sometimes extended into muscularis propria. Although longitudinal ulcers or scars, stricture, and a cobble-stone appearance were not observed, transmural inflammation and deep fissures were found in the interpolypoid area. From these findings, this case seems to be more similar to Crohn's disease than other inflammatory bowel diseases.

5/21. Penetrating atherosclerotic ulcer of the ascending aorta: a delayed complication of coronary artery bypass surgery--a case report.

    A 71-year-old woman, undergoing coronary angiography during preoperative evaluation for a major noncardiac surgery, was fortuitously detected as having penetrating atherosclerotic ulcer of the ascending aorta 5 years after coronary artery bypass surgery. While acute aortic dissections have been described after coronary bypass grafting, penetrating atherosclerotic ulcer of the ascending aorta as a delayed complication of bypass surgery has never been reported. The patient was treated conservatively and closely observed. A brief review of literature is also presented.

6/21. Laparoscopic colon resection with intraoperative polyp localisation with high resolution ultrasonography coupled with colour power Doppler.

    A 40-year-old woman with a 3 cm sigmoid polyp lesion who underwent a laparoscopic colon resection after intraoperative localisation of the lesion using laparoscopic ultrasonography coupled with colour power Doppler is described. She has successful intraoperative detection of the polyp followed by radical laparoscopic removal of the lesion. The advantage of using laparoscopic high resolution ultrasonography coupled with colour power Doppler to locate colonic polyp lesions during a laparoscopic colon resection is that intraoperative colonoscopy can be avoided. Intraoperative ultrasonography of the colon can accurately localise colonic polyp lesions that are not detectable during laparoscopy and represents a quick and effective alternative to other imaging techniques.

7/21. Appendicular intussusception into a polyp.

    intussusception of the appendix is a rare condition. We present the case of a 72-year-old woman with multiple polyps in the colon with an appendix completely intussuscepted into a polyp within the caecum. The clinical features, preoperative diagnosis, classification and treatment of this condition are discussed with reference to literature.

8/21. Small invasive colonic cancer occurring in a hyperplastic polyp.

    We report a case of advanced colon cancer which was supposed to have arisen from a hyperplastic polyp in a 68-year-old man. colonoscopy revealed a depressed reddish area with a surrounding elevated lesion that was of a faded color compared with the normal mucosa. After the mucosal surface had been sprayed with crystal violet dye, magnifying colonoscopy showed an amorphous area in the central depression and the surrounding, slightly elevated lesion had an asteroid pattern. The depressed area was therefore considered to be a colonic cancer surrounded by a hyperplastic polyp. Endoscopic ultrasonography showed that the lesion was infiltrating further than the deep submucosal layer and it was therefore decided to treat the patient by laparoscopically assisted right hemicolectomy. The depressed lesion was found to be a well-differentiated adenocarcinoma invading the muscularis propria (diagnosed as IIc IIa-like advanced adenocarcinoma). The surrounding flat elevated lesion was found to be hyperplastic mucosa. No adenomatous lesions were found. There have been few reported cases in which a preoperative diagnosis of carcinoma in a hyperplastic polyp has been made, but the possibility of carcinogenesis from hyperplastic polyps has come under consideration recently. This case was considered to be important because it raises the possibility that nonpolypoid cancer can develop from a hyperplastic polyp.

9/21. Early colon cancers detected by FDG-pet: a report of two cases with immunohistochemical investigation.

    Increased glucose uptake is one of the metabolic characteristics of tumor cells. 18F-fluorodeoxyglucose (FDG)-positron emission tomography (FDG-PET), a technique that is used widely to study this altered glucose metabolism in tumors, allows the detection of various types of malignancy. We present herein two cases of early colon cancers detected incidentally by FDG-PET. The technique was used as part of the screening examinations for preoperative staging, and for postoperative follow-up. In both cases, the lesions were removed by colonoscopic polypectomy, with no complications. Moreover, we confirmed the existence of altered glucose metabolism in the resected specimen by immunohistochemical staining using an antibody raised against Glut1. Immunohistochemically, Glut1 was expressed in vitro in both of the lesions, supporting the positive FDG-PET result obtained in vivo. To our knowledge, this is the first report to describe in vitro Glut1 expression and in vivo tumor detection using FDG-PET in colorectal carcinoma.

10/21. Diffuse giant inflammatory polyposis: a challenging clinicopathologic diagnosis.

    Giant inflammatory polyposis of the colon is an uncommon manifestation of inflammatory bowel disease. We report a unique case of localized diffuse giant inflammatory polyposis in a 58-year-old white man, which was characterized by recurrence following initial surgical resection. The patient presented with symptoms of abdominal pain and passing blood per rectum. Colonoscopic examination revealed a near-obstructing, "fungating" mass in the sigmoid colon, which clinically was thought to represent colon carcinoma. histology of several colon biopsies revealed marked acute inflammation with microabscess formation of the polyps and the adjacent mucosa. There was no evidence of dysplasia or malignancy. Because malignancy was strongly suspected and to relieve the obstructive symptoms, the patient underwent a segmental colectomy. The histologic features of the resected mass showed giant polyps with acute inflammation diagnostic of giant inflammatory polyposis. Again, there was no evidence of malignancy. Seven months later, following an uneventful initial postoperative recovery, the patient developed a recurrence of the mass with obstructive symptoms and required further surgical resection. The gross and histologic features of the lesion were similar to the previous findings. This case highlights the varied presenting symptoms and deceptive gross colonoscopic and radiologic features of localized diffuse giant inflammatory polyposis. Finally, the presence of inflammation at the resection margins appears to predict recurrence or persistence of the disease.
