ABSTRACT
Paraduodenal hernias are a rare congenital malformation, but they are the most common internal hernias. They develop secondary to a failure in midgut rotation, which may lead to small bowel obstruction or other clinical manifestations. The authors recently experienced a case of a left paraduodenal hernia presenting with unusual symptoms of left flank pain and vomiting.

Gallbladder torsion, also known as volvulus, is a rare condition that can be fatal unless surgery is performed expediently.AWe report a case of gallbladder torsion. A 92-year-old woman presented with acute abdominal pain. Laboratory parameters were all within normal limits, with the exception of leukocytosis. Plain abdominal radiography showed no remarkable findings. Abdominal CT revealed an abnormal gallbladder with wall thickening, suggesting the presence of acute cholecystitis. At operation, the gallbladder was twisted, and the wall of was thickened with acute inflammation. We report the details of this case along with a review of the literature.

A neuroendocrine carcinoma of the anal canal is a very rare entity; however, this type of tumor is known for its aggressive progression and poor prognosis. We describe the case of a 58-year-old female with a neuroendocrine carcinoma arising in the anal canal. The tumor was found in the anal canal with multiple liver metastases. The patient died due to massive liver metastases 11months after diagnosis and operation. For its rarity and clinical significance, we report the case with a review of the literature.

Gastrointestinal stromal tumors are the most common subset of mesenchymal tumors that arise from the gastrointestinal tract. They most commonly arise in the stomach, followed by the small bowel and, rarely, the rectum, esophagus and colon. Gastrointestinal stromal tumors and the specific c-kit protein (CD117)-positive mesenchymal tumors, have been sporadically reported in the rectum. We report here on a 12-year-old boy who underwent low anterior resection of huge gastrointestinal stromal tumor of the rectum. The diagnosis was confirmed by immunohistochemical staining of the tumor. The specimen was revealed to be a polypoid fungating tumor that, measured 6.0 x 6.0 cm in size, which consisted histologically of spindle-shaped cells. The tumor cells were positive for c-kit, vimentin, S-100, desmin, and SMA, although the results of the CD34 test were negative. In general, Gastrointestinal stromal tumors of the rectum predominantly occur between the sixth and seventh decades and they are rarely seen in individuals less than 40 years of age. To the best of our knowledge, our case is the youngest reported patient in the English literature who had as gastrointestinal stromal tumor of the rectum.

The amyloid deposition observed in secondary amyloidosis frequently involves the thyroid gland, but rarely is a goiter responsible for this. We report here the pathologic findings of a case of amyloid goiter with involvement of a parathyroid gland in an euthyroid patient. The patient presented with an enlarged thyroid, symptoms of upper airway obstruction and dysphagia.

Metastases from lung cancer to the gastrointestinal tract are not exceptional findings, but their clinical manifestations are rare. We report a new case of multiple metastases to the small bowel from primary lung cancer. A 67 year-old man presented with acute abdominal pain and vomiting. The laboratory investigations were all within normal limits except leukocytosis. Lung radiography was done and it showed infiltration at the right upper lung field without any mass. Abdominal CT-scan demonstrated a small bowel mass with ileoileal intussusception and the patient underwent emergency surgery. The postoperative lung studies and pathological analysis confirmed primary lung cancer with small bowel metastasis.

Insular carcinoma of the thyroid is a rare thyroid malignancy, and this was named in 1984 by Carcangiu when he described its characteristic histology. Histologically, insular carcinoma is characterized by uniform cells arranged in distinct nests or an insular pattern that contain variable numbers of small follicles. Clinically and morphologically, it is considered to be in an intermediate position between well-differentiated carcinoma of the thyroid (papillary or follicular) and undifferentiated or anaplastic carcinoma of the thyroid. This thyroid malignancy is distinctive, aggressive and often lethal. However, most authors believe it to be an independent entity. The prognosis of this tumor is worse than that of classic differentiated thyroid carcinoma, and most authors advise aggressive therapy, which can achieve pro-longed survival in some cases. We describe here a patient (a 42 years-old woman) who was managed with completion thyroidectomy after unilateral lobectomy of the thyroid with confirmation of the permanent pathology as insular carcinoma. I-131 ablation (175 mCi) was performed on the remnant thyroid tissues after follow-up of I~131 whole-body scanning.

PURPOSE: Local recurrence after curative resection of colorectal cancer has an important influence on both survival and quality of life. The ability to predict local recurrence after a curative resection of colorectal cancer may be useful for an intensive follow-up program and for a decision on adjuvant radiation or chemotherapy. The aim of this study was to analyze the factors affecting the incidence of local recurrence after a curative resection of colorectal cancer. METHODS: A retrospective review of 390 patients who had a curative resection for a primary colorectal cancer by a single surgeon at the Department of Surgery, Inha University Hospital, between June 1996 and July 2002 was done. The medical records of patients diagnosed with a local recurrence were reviewed. Local recurrence was defined as any recurrence within the field of resection, regardless of the presence or absence of distant metastasis, that was diagnosed by using colonoscopy with biopsy and/or radiologic imaging. RESULTS: Local recurrences were detected in 40 patients (10.3%). The gender distribution of patients with local recurrence was 24 males and 16 females with a mean age of 59.8 years. The median time to local recurrence was 15 months. The most common site of local recurrence was the anastomosis site, followed by a regional lymph node, the pelvicoperineal area, and the presacral area. Local recurrence was related to the depth of the primary tumor (P=0.027), lymphatics or vascular invasion (P=0.003), perineural invasion (P= 0.000), nodal status (P=0.000), and distant metastasis (P= 0.002). However, there was no statistically significant relation between local recurrence and primary tumor location (P=0.053), primary tumor size (P=0.982), tumor differentiation (0.256), and preoperative CEA level (P=0.481). CONCLUSIONS: The depth of the primary tumor, lymphatics or vascular invasion, and perineural invasion were significant clinicopathologic factors of local recurrence, but tumor location, tumor size, tumor differentiation, and preoperative serum CEA level were not.

Extramammary Paget's disease occurs commonly on the external female genitalia and rarely occurs in the perianal region. Recently, we experienced a case of perianal extramammary Paget's disease associated with an anal duct adenocarcinoma. The patient was a 60-year-old man. The perianal skin lesion was eczematous and encircled the anus. A wide-excision, split-thickness skin graft and temporal T-loop colostomy were performed. Histopathologically, the tumor was a well-differentiated anal duct adenocarcinoma. There was a prominent pagetoid spread of about 6x4 cm. The tumor cell was positive for carcinoembryonic antigen, but the paget cell was negative. The patient was treated with radiation therapy and with single 5-FU chemotherapy six times. Five months later, the perianal region was nearly normal.

PURPOSE: The anorectal function after a low anterior resection for rectal cancer recovered progressively by 6 12 months after the operation, but the mechanisms and the recovery process are not well understood. The aim of this study was to correlate postoperative anorectal function after low anterior resection with physiologic parameters. METHODS: Sixty-seven patients who underwent a low anterior resection for rectal cancer were studied. The control group was consisted of normal persons. Anorectal physiologic studies were conducted for 6 months postoperatively by using defecographys, anorectal manometry and electomyogram of pudendal nerve. RESULTS: The postoperative anorectal function was gradully improved with time. Defecograms showed that the resting, squeezing, and straining anorectal angles were not significantly increased. Anorectal manometry showed that the threshold volume and the urgency volume were not significantly decreased but the maximal tolerable volume was decreased remarkably. The maximal resting pressure significantly decreased but the maximal squeezing pressure were not. The pudendal nerve electromyograms were not significantly different between the two groups. The patients were divided by based on the anastomosis level. The short anastomosis group showed more impairment in the urgency volume and the maximal resting pressure than that of the long anastomosis group. CONCLUSION: The neorectal volume and the level of anastomosis were important for changes in the anorectal function after a low anterior resecton. Gradual improvement of symptoms resulted from a resected rectal adapted to a neorectal volum.
