A 51-year-old gravida 5 para 5 (5005) presented with an increasing abdominal girth and a palpable abdominal mass. She was initially diagnosed with ovarian new growth and underwent exploratory laparotomy. Intraoperatively, the uterus, Fallopian tubes, and ovaries were grossly normal and a large mass was seen attached to the cecum where the appendix should be referral to surgery service was done. Right hemicolectomy and ileostomy were performed. The histopathology report was “suggestive of a Müllerian adenosarcoma (MAS) involving the appendix and cecum.” Microscopic examination showed evidence of endometriosis with no evidence of sarcomatous overgrowth, features that are favorable prognostic factors associated with higher disease-free survival. Postoperatively, the plan of management was hormonal therapy. Extragenital MAS is rare. This case is the fourth case to be reported in the literature to arise from the colon. Although there is still no standard of treatment, accurate diagnosis is imperative for appropriate management.

From Feb. 1993 to Nov. 1996 at Viet Duc Hospital, 4 cases of ileum-cecum annatomosis and 7 cases of ileum-cecum intubation were performed. In 4 cases of annatomosis 3 had good result, 1 case had post operative peritonitis at the 8th day later due to anatomotic dehiscence, the two ends were exposed out of abdomen and the operation was repeated 1 month later. Right colon was cut and an end-end anastomosis was carried out, good result attained. The 7 cases of ileum-cecum intubation had good results

Appendiceal mucoceles are rare lesions. There has been only one report of a mucocele of the remnant appendix not communicating with the cecum. We report a remnant appendiceal mucocele following an incomplete incidental appendectomy, which presented as a lobulated cystic mass on ultrasonography and a cystic mass with an irregular wall on computed tomography. A borderline malignant mucinous tumor of the appendix was diagnosed.

Carcinosarcoma of the colon is rare. Seventeen cases have been reported in the English literature. Most cases occurred in the left side of the colon. Indeed, there is only one reported case of cecal carcinosarcoma. Carcinosarcoma has a tendency to distantly metastasize and shows dismal prognosis. We report a case of carcinosarcoma in the cecum and review the literature describing colonic carcinosarcoma.

Colorectal fecaloma is a mass of accumulated feces that is much harder in consistency than a fecal impactation. The rectosigmoid area is the common site for fecalomas and the cecum is the most unusual site. Diagnosis is usually made by distinctive radiographic findings of a mobile intraluminal mass with a smooth outline and no mucosal attachment. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, endoscopic procedures or a surgical intervention may be needed. We report here that a cecal fecaloma caused by intestinal tuberculosis scar was successfully removed by endoscopic procedures.

Duplications of the alimentary tract are relatively rare congenital malformations usually present during infancy or young childhood. They can occur anywhere in the intestinal tract. The most common site is the terminal ileum, and the least common site is the colon. Duplication of the cecum is very rare. The importance of these congenital lesions lies in the fact that they mimic other surgical disease processes and may result in significant morbidity if left untreated. Prompt recognition and treatment using combined radiologic and surgical management are associated with an excellent outcome. We experienced a case of cystic duplication in the cecum, which gave rise to partial intestinal obstruction and bleeding. We performed a resection of the cecum, including a part of the terminal ileum, and anastomosed in end-to-end fashion with a good result.

Stercoraceous ulcerations of the colon are produced by hard fecaloma that collect in the coton. Bleeding and more seriously perforation are complications of these ulcerations. These are generally thought to be rare, but this may reflect the difficulty of establishing the diagnosis, both before and during operation. This disease is relatively neglected as well. This is reflected by the small number of case reported in the literature. Authors report a case of stercoraceous ulcer of cecum which confirmed under the colonofiberscopy and managed in the Department of General Surgery, College of Medicine, Ewha Womans University,

BACKGROUND/AIMS: Loop formation during colonoscopy can adversely effect on completion rates, speed of intubation and patient tolerance of the procedure. The ability to vary endoscope shaft flexibility may help insertion to the cecum. The aim was to compare a variable colonoscope with adjustable shaft stiffness to a conventional colonoscope (CC). METHODS: Consecutive patients attending for day case colonoscopy were randomized for examination with either the conventional colonoscope (Olympus CF200Z) or a variable stiffness (VS) colonoscope (CFQ240AL). The time to the cecum, inserted length of scope at cecum, need for abdominal compression, need for rotation of body position and pain scores of patient were analyzed. RESULTS: Of 158 cases, 69 were performed with the CC, and 89 with VS. There was no difference in intubation time between VS (mean 5.15+/-2.61 min) and CC (6.01+/-3.31 min) in experienced group. However, intubation time was quicker with VS than with CC (VS: 8.48+/-5.59, CC: 11.58+/-4.70, p=0.039) and number of loop formation was less with VS (mean 1.20) than with CC (mean 1.84) (p=0.043) in trainee group. There were no significant differences in inserted length of scope at cecum, need for abdominal compression, pain score or need for patient rotation between VS and CC in two groups. CONCLUSIONS: There was no significant difference in cecal intubation time between two groups in experienced group. However, in trainee group, the intubation time was quicker and the number of loop formation were lower in VS group than CC group.

PURPOSE: To evaluate the usefulness of CT features of appendiceal mucocele in the diagnosis and evaluation of complications. MATERIALS AND METHODS: We retrospectively reviewed CT findings and compared with operative findings in 7 cases of pathologically proven appendiceal mucocele. CT findings such as location and extent of the lesion, Issue density, thickness or calcification of the wall, presence of adjacent inflammatory infiltration, and visualization of normal vermiform appendix were analyzed. RESULTS: Appendiceal mucocele was found as homogeneous low density cystic mass adjacent to the cecum, which has no surrounding inflammatory infiltration except in one case of perforation and one case of intussusception. Mean CT number measured in 4 cases was 21 Hounsfield unit. Thin curvilinear calcifications were noted along the cystic wall in 2 cases. Normal vermiform appendix couldn't be demonstrated in all cases. CONCLUSION: Appendiceal mucocele is characterized by homogeneously low density and thin walled cystic tumor adjacent to cecum without surrounding inflammatory infiltration, and absence of normal vermiform appendix on CT. Therefore, CT is valuable in preventing operative complications of appendiceal mucocele.
