The differential diagnosis for lower abdominal and pelvic pain following Cesarean section includes many causes, such as endometritis, abscess, pelvic hematoma, wound complications, pelvic vein thrombophlebitis, gastrointestinal dysfunction and obstruction. Colonic obstruction secondary to intussusception is a rare cause. We present a case of post-Cesarean section pain in a 26-year-old patient due to obstructing colonic intussusception secondary to colonic adenocarcinoma. Review of the literature failed to identify a previous case report of colonic adenocarcinoma with intussusception presenting early in the postpartum period. The diagnosis was initially made by ultrasound, and later corroborated by computed tomography, barium enema and laparotomy.

Two adult patients with intussusception were both diagnosed by colonoscopic investigation. The first patient, a woman aged 39, suffered from persisting abdominal discomfort with nausea and vomiting. Ultimately an ileo-ileocolic intussusception caused by an inflammatory fibroid polyp of the ileum was found. The other patient, a man of 79 years, complained of subacute cramping pain in the right lower abdomen. This was due to an ileocolic intussusception caused by an adenocarcinoma of the cecum. Both patients underwent an ileocecal resection; their postoperative courses were uneventful.

The unusual occurrence of an "inside-out" appendix reported here is a case of complete intussusception of the appendix of a 45-year-old woman with Peutz-Jeghers syndrome in whom the diagnosis of intussusception was made preoperatively. At laparotomy, the lead point of intussusceptum was revealed to be a Peutz-Jeghers syndrome polyp of the appendix. There was also a cystic lesion in the pancreas, and subsequent distal pancreatectomy revealed a cystadenocarcinoma of the pancreas. Two jejunal Peutz-Jeghers syndrome polyps and two duodenal Peutz-Jeghers syndrome polyps were found via intraoperative endoscopies. The duodenal polyps were endoscopically removed, whereas a jejunal wedge resection was performed for the adjoining jejunal polyps. One of the two duodenal polyps possessed an adenocarcinoma focus. To our knowledge, this is the first report of complete intussusception of the appendix caused by a Peutz-Jeghers syndrome polyp.

We report a case of lung cancer metastatic to the stomach and the jejunum. Adenocarcinoma of the lingula (T 4 N 2 M 0) was diagnosed in a 45-year-old man, who then underwent chemoradiotherapy. Bowel obstruction later developed due to jejunal metastasis. Another metastasis was detected in the stomach. Laparotomy revealed jejuno-jejuno-jejunal intussusception caused by the two lesions. The jejunal and gastric lesions were identified as metastatic large cell carcinoma arising from the lung. One month postoperatively, the patient died due to disease. The literature has demonstrated that large cell carcinoma of the lung tends to metastasizes. However, the complex bowel invagination and gastric metastasis seen in our case are rare.

We present herein a case report of vanishing colon cancer with intussusception. A 70-year-old man with hematochezia was admitted to our hospital. Preoperative images showed ileus due to a colonic tumor. At operation, normograde intussusception without any tumor was recognized at the sigmoid colon. Interestingly, the regional lymph nodes were found to be invaded by tubular adenocarcinoma cells, thus suggesting that the colon cancer existed before the necrosis of the wall took place.

The authors present the case of a 17-year-old girl with tuberous sclerosis (TS) who presented with symptoms of intussusception. Although endoscopically diagnosed with multiple colonic polyps, presumed to be hamartomas, and an invasive rectal adenocarcinoma, postoperative pathology findings confirmed the rectal cancer and showed multiple colonic adenomas. Multiple colonic adenomatous polyps in a young girl with tuberous sclerosis is extremely rare. Furthermore, we believe that this is the first report of an invasive adenocarcinoma of the large intestine occurring in a patient with TS.

Appendiceal intussusception is an uncommon pathologic condition; however, villous adenoma of the appendix is a distinctly rare entity. We report herein a case of appendiceal intussusception induced by tubulovillous adenoma with carcinoma in situ. A 67-year-old man was admitted to our hospital with a 1-year history of lower abdominal pain for investigation. Barium enema showed a filling defect with an irregular surface in the cecum, and colonoscopy revealed a cecal tumor with a granular surface. Pathological examination of biopsy samples revealed tubulovillous adenoma with well-differentiated adenocarcinoma, and a diagnosis of cecal cancer in tubulovillous adenoma was made. Surgery was performed and the resected specimen was found to contain a tumor arising from the appendix. The tumor was 5.5 x 4.5 cm in size in the cecal cavity, and the appendix had invaginated into the cecum at its base. The cut surface of the appendix showed the villous tumor filling the appendiceal lumen and projecting into the cecal cavity. Microscopic examination revealed well-differentiated adenocarcinoma in tubulovillous adenoma. To the best of our knowledge, this is the first report of appendiceal intussusception caused by tubulovillous adenoma with carcinoma of the appendix.

Although small bowel obstruction is a common occurrence, it is essential that this clinical condition be treated properly, that the site, level, and cause of obstruction be determined accurately, and that a tentative prognosis be formulated prior to surgery. The diagnosis of small bowel obstruction is based on a comprehensive approach that includes clinical background, patient history, and results of physical examination and laboratory tests. A variety of radiologic procedures are available to aid in the diagnosis of small bowel obstruction. Recent studies have demonstrated the superiority of CT in revealing the site, level, and cause of obstruction and in demonstrating threatening signs of bowel inviability. CT has proved useful in characterizing small bowel obstruction from extrinsic causes (adhesions, closed loop, strangulation, hernia, extrinsic masses), intrinsic causes (adenocarcinoma, Crohn disease, tuberculosis, radiation enteropathy, intramural hemorrhage, intussusception), intraluminal causes (eg, bezoars), or intestinal malrotation. Conventional radiography was the modality of choice for many years and should remain the initial imaging method in patients with suspected small bowel obstruction. However, the unique capabilities of CT in this setting make this modality an important additional diagnostic tool when specific disease management issues must be addressed.

Intussusception accounts for almost all cases of intestinal obstruction in children. In contrast, intussusception in adults is relatively rare. An 86-year-old Japanese female with rectal bleeding came to our hospital via ambulance. At first, colonoscopy findings revealed the sigmoid colon cancer. Ultrasonography showed a hypoechoic mass with a multiple concentric ring sign. Computed tomography showed a round fluid-filled cystic structure. Colon contrast studies demonstrated stenosis in the rectosigmoid colon. A laparotomy was performed. The sigmoid colon was intussuscepted to the rectosigmoid colon. We employed both rectosigmoid and sigmoid colon resection. The resected specimen showed that the disease was advanced sigmoid colon cancer with ulcer formation due to an ischemic change. Tumor was 4.5 cm x 2.0 cm in size. The disease was histopathologically diagnosed as advanced sigmoid colon cancer, well-differentiated adenocarcinoma. We report here a case of adult intussusception due to the sigmoid colon cancer.

Small intestinal neoplasms are uncommonly encountered in clinical practice. They may occur sporadically, in association with genetic diseases (e.g., familial adenomatous polyposis coli or Peutz-Jeghers syndrome), or in association with chronic intestinal inflammatory disorders (e.g., Crohn's disease or celiac sprue). Benign small intestinal tumors (e.g., leiomyoma, lipoma, hamartoma, or desmoid tumor) usually are asymptomatic but may present with intussusception. Primary malignancies of the small intestine-including adenocarcinoma, leiomyosarcoma, carcinoid, and lymphoma-may present with intestinal obstruction, jaundice, bleeding, or pain. Extraintestinal neoplasms may involve the intestine via contiguous spread or peritoneal metastasis. Hematogenous metastases to the intestine from an extraintestinal primary are unusual and are most typical of melanoma. Because the small intestine is relatively inaccessible to routine endoscopy, diagnosis of small intestinal neoplasms is often delayed for months after onset of symptoms. When the diagnosis is suspected, enteroclysis is the most useful imaging study. Small bowel endoscopy (enteroscopy) is increasingly widely available and may permit earlier, nonoperative diagnosis.
