Two patients with papillary tumors of the pancreas are reported. In both cases, the tumors occurred in women (62 and 60 years of age) who presented with upper abdominal mass and abdominal fullness. The resected tumors were 14 X 16 cm and 13 X 10.5 X 8.3 cm, respectively. Their histology resembled that of the papillary tumor of the pancreas reported by Frantz (1959). The ultrastructural details, including numerous mitochondria, basement membrane and no evidence of secretory or zymogen granules, suggest pancreatic duct cell origin. The first patient died of colon cancer six years and 10 months postoperatively. The second patient is without signs of recurrence five months after resection.

The purpose of this study was to evaluate the pattern of recovery of intestinal motility using manometric and clinical assessment in the postoperative ileus following abdominal surgery. We reviewed the charts of 18 patients who underwent partial colectomy for colon cancer (group A, without vagotomy) and compared them to those of 15 patients who underwent gastrectomy with truncal vagotomy and reconstruction by the Billroth I technique (group B, with vagotomy). A three-lumen catheter was inserted via the nose into the proximal jejunum for drainage of intestinal fluids and to record intestinal motility at laparotomy. The first appearance of a burst activity following a silent period and a migrating motor complex (MMC) was at 3.8 hours (mean) and 16.4 hours, respectively, in group A, and at 2.5 and 14.3 hours, respectively, in group B. The first audible bowel sounds and the time of feeling abdominal fullness and passage of flatus was at 34.8, 47.5, and 62.9 hours (group A), and at 43.0, 53.8, and 77.9 hours (group B), respectively. The peak volume of nasointestinal drainage was recorded at 16 to 24 hours in group A and 40 to 48 hours in group B (p < 0.05). As measured by manometric examination, an MMC reappeared within a few hours after surgery. Physiologic postoperative ileus was ended when MMCs extended throughout the gastrointestinal (GI) tract with forwarding GI fluids.

A 72-year-old woman was admitted with a complaint of a sensation of abdominal fullness. Cytologic examination of ascites revealed many poorly differentiated adenocarcinoma cells. Barium enema study and colonoscopy revealed IIa+IIc-type carcinoma of the descending colon. Endoscopic mucosal resection was performed to determine the histological type and the depth of invasion. The resected tumor was 7 x 6 mm in size, and an amorphous pit pattern was observed in the depressed area by stereomicroscopy. Poorly differentiated adenocarcinoma with signet-ring cells had diffusely infiltrated into the deeper part of the submucosal layer. Immunohistochemical findings showed this tumor to have mucin derived from gastric foveolar epithelium, suggesting that the signet-ring cell carcinoma of the colon showed gastric differentiation. Primary signet-ring cell carcinoma of the colon and rectum is a rare form of adenocarcinoma of the large intestine and shows more malignant biological behavior than ordinary colorectal carcinoma. Early diagnosis and curative operation are important.

We report an extremely rare case of pseudo-Meigs' syndrome caused by ovarian metastases from colon cancer, and review the literature on this unusual entity. A 41-year-old woman was admitted for investigation of abdominal fullness and dyspnea. Preoperative examinations revealed a huge pelvic tumor, adenocarcinoma of the sigmoid colon, marked ascites, and bilateral pleural effusion. Laparotomy confirmed that the huge mass was comprised of bilateral ovarian tumors. Resection of the sigmoid colon and bilateral oophorectomies were performed. Although short-term intrathoracic drainage was required, the hydrothorax and ascites rapidly resolved in the postoperative period. The patient died of disseminated liver and bone metastases 8 months after her operation; however, ascites and hydrothorax were not clinically noted until death. This and five other reported cases demonstrate that ovarian metastasis from colorectal cancer may occasionally cause pseudo-Meigs' syndrome, and that resection of the ovarian lesions could improve the prognosis.

Colonic perforation caused by upper gastrointestinal (GI) endoscopy is extremely rare. A 69-year-old woman was referred to our hospital because of abdominal fullness. Colonoscopy could be performed only up to the hepatic flexure due to an elongated colon and residual stools. Because her symptoms improved, upper GI endoscopy was performed 11 days later. The patient developed severe abdominal pain two hours after the examination. Abdominal X-ray and computed tomography showed massive free air. Immediate laparotomy was performed for the intestinal perforation. After removal of stool, a perforation site was detected in the cecum with an invasive ascending colon cancer. Therefore, a right hemicolectomy, ileostomy, and transverse colostomy were performed. Although she developed postoperative septicemia, the patient was discharged 38 days after admission. Seven months postoperatively, the patient died of lung, liver, and brain metastases. Even in cases with a lesion that is not completely obstructed, it is important to note that air insufflations during upper GI endoscopy can perforate the intestinal wall in patients with advanced colon cancer.

A 64-year-old woman visited our outpatient clinic because of bloody stools and abdominal fullness. Digital rectal examination revealed a 6 x 4-cm oval mass. Abdominal CT scans demonstrated a concentric, multilayered structure in the rectum. Colonoscopy showed segments of the bowel were dark-purplish, and intussusception. Deeper insertion of the colonoscope through the lumen revealed a type 1 lesion. Under a diagnosis of sigmoid colon cancer with intrarectal intussusception, emergency surgery was performed. The resected specimen showed a type 1 advanced cancer and two early cancers at the base of the intussuscepted colon, all of which appear to have contributed to the intussusception.

A 44-year-old female was referred to our hospital with a complaint of abdominal fullness. Computed tomography(CT) showed multiple liver masses and a huge ovarian tumor. Colonoscopy revealed a type 4 advanced cancer in the sigmoid colon. She was diagnosed with unresectable liver and ovarian metastases from advanced sigmoid colon cancer, for which we were obliged to select chemotherapy. As the first line, FOLFOX was applied and performed for 6 cycles, followed by FOLFOX plus bevacizumab(BV)for 5 cycles. While no deterioration of liver and ovarian metastases was observed during the course of those chemotherapy regimens, the patient developed a considerable level of acute sensorimotor neuropathic symptoms associated with oxaliplatin-induced peripheral neurotoxicity, forcing us to replace FOLFOX plus BV with FOLFIRI plus BV. Three cycles of FOLFIRI plus BV, however, turned out to be progressive disease with deterioration of liver and ovarian metastases. Since her oxaliplatin-induced neurotoxicity was improved, a regimen of FOLFOX plus BV was once again applied to her for 3 cycles, which failed to prevent her from having a progressive disease. The sequencing of K-RAS genes from the biopsy specimens of sigmoid colon cancer revealed an expression of a wild-type K-RAS. Thus, an addition of panitumumab to FOLFOX was made. Surprisingly, after 3 cycles of the chemotherapy regimen over 3 months, a significant reduction in the size of liver and ovarian metastases was observed. Her sense of abdominal fullness was apparently reduced and was even lower than what it was at admission. Panitumumab has great potential for effective treatment of patients with unresectable stage IV colorectal cancer, even after having acquired resistance to prior chemotherapy regimens.

A 68-year-old woman presented to our hospital with abdominal fullness. Computed tomography(CT)revealed ascites and massive tumors in the abdominal cavity. She was diagnosed with ascending colon cancer with peritoneal dissemination and ovarian metastasis. After ileostomy, panitumumab plus mFOLFOX6 therapy was initiated, but it was discontinued due to adverse events. As the ascites rapidly increased, her chemotherapy was changed to bevacizumab(BV)plus FOLFIRI. BV combination therapy resulted in a dramatic decrease in ascites and improved her quality of life, whereas the therapy did not reduce the primary and metastatic lesions. Our case suggested that BV could decrease ascites by inhibiting vascular endothelial growth factor(VEGF)-induced vascular permeability.

We report here a rare case of gastric metastasis after resection ofa transverse colon cancer in which eating ability was restored following mFOLFOX6 (folinic acid plus fluorouracil plus oxaliplatin) plus cetuximab (Cet) chemotherapy. A 56-year-old man with chief complaints of constipation and abdominal fullness was referred to our hospital. In February 2013, he was diagnosed with transverse colon cancer via enema and colonoscopy. We performed transverse colon cancer resection followed by a 6-month course of capecitabine chemotherapy. In July 2014, the patient's serum carcinoembryonic antigen level increased, in October, he was again referred to our hospital with complaints of appetite loss and vomiting. He was diagnosed with multiple lymph node and gastric metastases via ultrasonography, computed tomography, and endoscopy, as well as multiple lung metastases via computed tomography. As the gastric metastases and vomiting rendered him unable to eat, a nasogastric tube was inserted and was administered mFOLFOX6 plus Cet chemotherapy. After 2 courses of chemotherapy his ability to eat was restored. As of March 2015, the patient remains alive following 12 courses of chemotherapy.

The patient was a 41-year-old woman. When she was 39 years old, she had undergone laparoscopic high anterior resection for sigmoid colon cancer without adjuvant chemotherapy. Histologically, the surgical specimen was type 2, tub2, pT4a (SE), pN0, int, INF b, ly1, v1, and pStage II. Nine months after the operation, she suffered from abdominal fullness. Laborato- rydata showed elevation of tumor markers: the CEA level was 6.48 ng/mL, the CA19-9 level was 89.70 U/mL, and the CA125 level was 662 U/mL. Computed tomographyrevealed bilateral ovarian tumors and lung and peritoneal nodules with massive ascites. Chemotherapywas started with a regimen consisting of capecitabine plus oxaliplatin(CapeOX)that included bevacizumab. After 4 courses, the sizes of the lung and peritoneal nodules had decreased and the amount of ascites was almost zero. However, the ovarian tumors had increased in size and her sense of abdominal fullness had not improved. Bilateral oophorectomy with hysterectomy was performed to alleviate her symptom. Immunohistochemically, the resected ovarian tumors were negative for cytokeratin 7 and positive for cytokeratin 20. CapeOX with bevacizumab was then resumed. However, the lung tumor had graduallyincreased in size, and therefore, she underwent partial resection of the lung for the metastatic lung tumor.
