[A Case of Intussusception Caused by Descending Colon Cancer].

A46 -year-old male presented with bloody stool and a descending colon tumor, as identified using colon fiberscopy. The patient did not complain of any remarkable abdominal symptoms. Computed tomography revealed descending colon tumor intussusception. We performed partial resection of the descending colon and D2 lymphadenectomy without intraoperative reduction. The descending colon was barely attached to the retroperitoneum and was mobile. The underlying tumor was type 1 and measured 8.3×5.8 cm. The pathology report indicated a mucinous adenocarcinoma with extension through the submucosa into the subserosa, and metastasis in 6 nearby lymph nodes(n2). Intussusception is relatively rare in adults, particularly in portions of the colon fixed to the retroperitoneum, such as the descending colon. In contrast to previous reports of descending colon intussusception caused by age-related tissue dysfunction, we report our experience with a young patient and present the results obtained.

Incarcerated Small Bowel Herniation in a Stoma Mimicking Sigmoid End Colostomy Prolapse.

Introduction: A stoma prolapse is easy to diagnose by visual examination, and it rarely incarcerates. Therefore, manual reduction is usually performed as soon as the diagnosis is made. In this report, we describe a case of stoma prolapse that could not be reduced manually and ruptured because an incarcerated parastomal hernia occurred in the stoma, mimicking stoma prolapse. Case Presentation: A 66-year-old woman underwent total hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, omentectomy, resection of dissemination, and low anterior resection with formation of a sigmoid end colostomy for endometrial cancer with infiltration of the rectum. Fourteen months after the initial operation, she presented with stoma prolapse and multiple episodes of vomiting. The prolapsed stoma was 20 cm in length, appeared swollen and edematous, and was somewhat firm. Although it looked viable, some of the mucosa was darkish red, indicating congestion. Therefore, the diagnosis was sigmoid end colostomy prolapse with an ischemic component. An attempt at manual reduction resulted in rupture, so an emergency laparotomy was performed. Intraoperatively, we found that the ileum was incarcerated in the aperture created where the colostomy had been formed. When the incarcerated ileum was released, the stoma prolapse could be reduced easily. The end colostomy was refashioned in the left upper quadrant of the abdomen. Conclusion: An incarcerated parastomal hernia can mimic stoma prolapse. If the findings differ from those of typical stoma prolapse, imaging should be performed to confirm whether another clinical entity is involved in the stoma prolapse.

[Eighty-five-year-old patient with recurrent rectal cancer effectively treated with CapeOX chemotherapy].

We report a case of a super-elderly patient with recurrent rectal cancer effectively treated with CapeOX chemotherapy. A 85-year-old man who had a low anterior resection was diagnosed with rectal cancer in July 2009. Although peritoneal dissemination near the main tumor was disclosed during the operation, a R0 and Cur B operation was performed. After the operation, an elevation of tumor markers was detected in October. A chest-abdominal-pelvic CT scan revealed multiple liver metastases of the bilateral lobe and a metastasis of the right iliac bone. We attempted CapeOX chemotherapy from November. After 3 courses of CapeOX chemotherapy, the multiple liver metastases shrank and the bone metastasis changed to a consolidation. Although grade 1 chronic peripheral neuropathy appeared after 8 courses of chemotherapy, no other adverse event appeared. After 10 courses of CapeOX chemotherapy, the chemotherapy was changed to capecitabine at the patient's request. A chest-abdominal-pelvic CT scan after 10 courses of CapeOX chemotherapy revealed that the multiple liver metastases were shrinking. As of September 2010, the patient's PS score is 0, and he has been under treatment as an outpatient.

Celiac axis stenosis in pancreaticoduodenectomy.

BACKGROUND/PURPOSE: Celiac axis (CA) stenosis is a fairly common condition in candidates for upper abdominal surgery. In this report, we have documented 5 patients with CA stenosis or occlusion who underwent pancreaticoduodenectomy, and we have discussed the surgical strategy for this condition. METHODS: We reviewed the records of 126 patients who had undergone resection of the pancreatic head during the past 10 years, and a search was made for obstructive lesions of the CA. RESULTS: Among these 126 patients, there were 5 cases (4%) of CA stenosis or occlusion. Three of them were interpreted as typical CA compression syndrome, based on arteriographic or operative findings, and an excision of the median arcuate ligament dramatically improved the blood flow of the celiac branches after division of the main collaterals. The remaining 2 patients, with organized occlusion of the CA, successfully underwent pancreaticoduodenectomy through preservation of the collateral pathway between the superior mesenteric artery and the celiac branch. In one of these 2 patients, the main collateral pathway, which ran across immediately behind the pancreatic head, was skeletonized and preserved. All 5 patients had uneventful postoperative courses. CONCLUSIONS: We conclude that, in pancreaticoduodenectomy for patients with organized CA occlusion, precise assessment of the vascular anatomy and preservation of the main collateral pathway are essential for carrying out a successful operation. Celiac axis (CA) stenosis is a fairly common condition in candidates for upper abdominal surgery. In this report, we have documented 5 patients with CA stenosis or occlusion who underwent pancreaticoduodenectomy, and we have discussed the surgical strategy for this condition.

An early cancer of the gastric cardia arising from carditis after long-term gastroesophageal reflux disease in the absence of Helicobacter pylori infection.

We describe an early gastric cardiac cancer in a patient who had suffered long-term gastroesophageal reflux disease (GERD) but showed no evidence of infection with Helicobacter pylori. Proximal gastrectomy and partial resection of the lower esophagus was performed. Histological examination revealed the lesion to be a gastric cardiac adenocarcinoma, which had partially invaded the submucosal layer. Intestinal metaplasia was also found in some areas. Inflammation, however, appeared to be limited to the gastric cardia. This cancer may have arisen via a sequence of carditis and cardiac intestinal metaplasia, due primarily to the GERD and not to H. pylori infection.

Endoscopic findings of adenocarcinoma arising from short-segment Barrett's esophagus.

Adenocarcinoma arising from short-segment Barrett's esophagus (SSBE) is rare in Japan, although the incidence of this condition is increasing in Western countries. Four cases of early adenocarcinoma arising from SSBE were diagnosed and treated at Niigata-prefectural Yoshida Hospital. All patients were male, variously 55, 71, 73 and 79 years of age. All four patients had long-term gastroesophageal reflux disease, although one patient had erosive esophagitis and three patients did not have erosive esophagitis. Three patients were diagnosed as having Helicobacter pylori-free stomach. All adenocarcinomas occurred close to the squamocolumnar junction. Patients with SSBE should undergo detailed endoscopic examination of the squamocolumnar junction in order to detect early adenocarcinoma arising from SSBE.
