1/187. Colonic obstruction due to sigmoid muscular hyperplasia.We report a case of acute colonic obstruction initially presumed to be secondary to acute diverticulitis, necessitating emergent surgical intervention. Pathologic examination failed to reveal evidence of inflammation, fibrosis or neoplasia. Marked hypertrophy of the sigmoid circular muscle layer was documented and thought to be the etiology of the colonic obstruction.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
2/187. Renal fibrohistiocytic sarcoma. Three cases and a review of the literature.The purpose of this paper is to report three unpublished cases of so-called "renal malignant fibrous histiocytoma" which should be more appropriately called "renal fibrohistiocytic sarcoma", and to review and analyze the data concerning 41 cases collected from the literature and our three new cases, making a total of 44 cases. Our third case is very interesting; in addition to the fact that this condition is rare, this particular patient also had concomitant nonmalignant ascites and compression of the descending colon, both conditions being rarely associated with renal cancer. The average age of the patients was 58 years; in 66% of the cases the tumor involved the left kidney; 57% of the patients were males; the average tumor size was 12 cm; nephrectomy was performed in 93% of the cases; the average survival was 16 months. In none of the cases was a preoperative diagnosis correctly made. It is concluded that a triad of symptoms and signs (renal pain, weight loss, and large tumor size) as well as a triad of imaging characteristics (areas of low density on the CT scan, hypoechoic areas on ultrasound, and hypovascularity on angiography) may hold the promise of a preoperative diagnosis. It is suggested that the tumor arises from the system of Gerota's fascia-renal capsule.- - - - - - - - - - ranking = 8.0090477813606keywords = cancer (Clic here for more details about this article) |
3/187. ileus with incarceration of Spigelian hernia.An 85 year-old female with ileus due to incarceration of Spigelian hernia, which was diagnosed pre-operatively with the findings of the abdominal computed tomography and plain radiographic pictures, is reported. A simple hernioplasty was made by suturing the internal oblique and transverse muscles to the rectus sheath. The post-operative condition is satisfactory without any recurrence of hernia.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
4/187. Intestinal blockage by carcinoma and blastocystis hominis infection.We detected heavy infections of blastocystis hominis in four individuals with intestinal obstruction due to cancerous growths. After surgery, the infections spontaneously resolved, without specific chemotherapy. It appears that the B. hominis infection was coincidental and not related to the neoplastic growth. We suggest that intestinal obstruction and concomitant stool retention, plus hemorrhage from cancerous lesions, may have permitted the more abundant growth of B. hominis. This is the first report of a possible relationship between intestinal obstruction and a concomitant B. hominis infection.- - - - - - - - - - ranking = 16.018095562721keywords = cancer (Clic here for more details about this article) |
5/187. Small bowel obstruction secondary to herniation through a 5-mm laparoscopic trocar site following laparoscopic lymphadenectomy.Incisional hernias occur in <1% of women undergoing operative laparoscopy and are mostly limited to trocar sites > or =10 mm. This is a report of a 54-year-old woman with endometrial cancer who presented with nausea, vomiting and abdominal pain 1 week following laparoscopically-assisted vaginal hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy. Abdominal radiographs and computed tomography demonstrated small bowel obstruction and herniation through a 5-mm trocar site. Reduction of the hernia and closure of the fascial incision were performed at exploratory laparotomy with normal recovery. Bowel herniation can occur through 5-mm trocar sites following prolonged operative laparoscopy. The peritoneum and fascia of these incisions should be closed.- - - - - - - - - - ranking = 8.0090477813606keywords = cancer (Clic here for more details about this article) |
6/187. Localized AL amyloidosis of the colon and clinical features of intestinal obstruction. A case report.The term amyloidosis refers to a group of disorders characterized by the extracellular accumulation of insoluble, fibrillar proteins (i.e. amyloid) in various organs and apparatuses. Local deposition of amyloid without systemic involvement is a rather uncommon form that gives rise to an amyloid pseudo-tumor or "amyloidoma". This paper describes the clinical features of an intestinal subocclusion observed in an elderly patient with localized primary amyloidosis of the transverse colon. The endoscopic picture indicated a stenosing neoplasm. Segmentary colectomy, however, followed by histological examination (characteristic green color in polarized light after staining with congo red) and immunohistochemical analysis of the resected tissue, revealed massive deposits of amyloid composed of lambda light chains in the interstitial connective, and perivascular tissue and muscular tunic, and resulted in a diagnosis of AL amyloidosis. This was successfully treated with a combination of melphalan and prednisone.- - - - - - - - - - ranking = 0.13438062840431keywords = neoplasm (Clic here for more details about this article) |
7/187. Intrauterine volvulus without malrotation associated with segmental absence of small intestinal musculature.A case of intrauterine intestinal volvulus without malrotation is presented, and 9 other cases from the world literature are reviewed. Bloody diarrhea, bluish discoloration of the abdominal wall (Cullen's sign), and a tense abdomen in neonates suggest midgut volvulus requiring prompt surgical management. On pathological examination, the neck of the twisted bowel in this case showed a half-circle defect of the intestinal muscle. This suggests that a segmental defect of the intestinal musculature could be secondary to volvulus.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
8/187. Case report: adenocarcinoma arising in a Crohn's stricture of the jejunum.patients with Crohn's disease affecting the small intestine appear to have an increased risk of developing adenocarcinoma. However, it remains an uncommon complication of an uncommon disease. The diagnosis is difficult to make both pre- and intra-operatively, and is most commonly made postoperatively on histopathology. Hence, at laparotomy, consideration should be given to performing a frozen section on all small bowel strictures due to Crohn's disease to define the presence of dysplasia or cancer. This will assist the surgeon in deciding whether to perform a stricturoplasty or a resection.- - - - - - - - - - ranking = 8.0090477813606keywords = cancer (Clic here for more details about this article) |
9/187. Recurrent mesenteric desmoid tumors with multiple peritoneal dissemination: a case report and review of desmoid in japan.We report, herein, on the first case of a mesenteric desmoid tumor with multiple peritoneal dissemination. A 73 year-old Japanese woman, who had a history of uterine cancer that was treated with hysterectomy followed by a high dose of irradiation 25 years ago, had an unknown stenosis of the sigmoid colon, which was treated with partial resection of the stenosed colon 6 years ago, and then resulted in multiple small bowel obstructions due to the recurrence of mesenteric desmoids. The clinical behavior of this tumor is considered to be unpredictable. We emphasize that mesenteric desmoid tumors should be considered as one of the causes of stenosis of the colon and small bowel, and patients should receive careful follow-up after unknown stenosis.- - - - - - - - - - ranking = 8.0090477813606keywords = cancer (Clic here for more details about this article) |
10/187. Malar metastasis from rectal carcinoma: a case report.Facial metastasis from colorectal carcinoma is extremely rare. Only two cases have been reported in the literature. This is the first reported case of malar metastasis from colon carcinoma. The patient was a 64-year-old, white woman who underwent a low anterior resection for a nearly obstructive carcinoma at 20 cm. Her chest X-ray revealed lung metastases. Postoperatively she was treated with fluorouracil and leucovorin. Twenty months later, she presented with left facial edema, which progressively increased in size. CT scan and magnetic resonance imaging with gadolinium showed a large soft tissue mass centered about the left anterior zygomatic arch. The platysma muscle was displaced laterally, and the masseter muscle was involved. There was extension into the masticator space and bony involvement of the zygomatic arch. True-cut biopsy of the left cheek revealed metastatic adenocarcinoma. histology was similar to that of the primary rectal adenocarcinoma. Metastasis to the malar region is extremely rare. It is a grave prognostic sign, as it is associated with advanced terminal disease. Because of the widespread metastases, only palliative treatment can be provided.- - - - - - - - - - ranking = 2keywords = muscle (Clic here for more details about this article) |
