While diverticulosis of the colon is a relatively common disease, a solitary giant colonic diverticulum is rare. Although there exist some theories about the formation of the giant colonic diverticulum, none is really conclusive. The preoperative diagnosis of giant colonic diverticulum is made radiographically with findings of a large, smoothly marginated, round homogeneous radiolucency in the abdomen that is in close apposition to the colon on barium enema examination. Early surgical treatment is necessary since the complication rate is high. One case of giant colonic diverticulum is presented, the clinical, radiologic and pathologic findings are discussed, and the etiology and differential diagnosis, reviewe.

PURPOSE: Diverticular disease of the colon is relatively common in western population and rare in oriental population but in recent years the incidence is steadily increasing in oriental population including Korean, so more concerns and appropriate management are required. METHODS: We reviewed 111cases who had diverticular disease in the colon from January 1988 to May 1998 in the Soonchunhyang University Chunan Hospital. Of 111 cases, 87 cases were treated conservatively and 24 cases received a surgical treatment. RESULTS: The annual incidence increased progressively for the last 10 years. The mean age of the patients at the time of diagnosis was 49.6 years and the most common age-group was forth decades (25%). The diverticula were located in the right colon 89%, left colon 7% and both side 4%. Among 24 surgically treated cases, the most common preoperative diagnosis was acute appendicitis (75%) and the correct preoperative diagnosis was made only 3 cases (13%) who had previous appendectomy history, previous diagnosed history or received barium enema due to recurrent pain attack. The surgical procedures of the colonic diverticulosis were right hemicolectomy (6 cases), ileo-ascending colectomy (6 cases), diverticulectomy (2 cases), segmental resection of transverse colon (1 case), left hemicolectomy (1 case), appendectomy (2 cases), appendectomy with drainage (3 cases), appendectomy with drainage and diverticulectomy (3 cases). The postoperative complication was wound infection in all complicated cases. There was no postoperative mortality. CONCLUSIONS: The outcome of patients in our series is satisfactory despite of diagnostic inaccuracies. Preoperative barium study is recommended in those above the 40 years of age suspected the appendicitis. We recommend surgery for patients after two or three episodes of acute diverticulitis that resolves after medical treatment with antibiotics.

Despite a recent trend toward increased screening and public awareness for colorectal cancer, 30% of patients present with incurable disease. This study was designed to identify objective criteria that might help surgeons decide which patients with incurable colorectal cancer will benefit from palliative resection. Among 33 patients considered incurable colorectal cancer, twenty one patients underwent palliative resection and twelve patients had bypass surgery. Incidence of postoperative complication after palliative resection was 61.9%(13 cases), and after bypass surgery was 58.3%(7 cases). Among patients treated by palliative resection, one patient required reoperation for postoperative bleeding. The operative mortality after palliative resection was 19%(4 cases), and after bypass surgery was 25%(3 cases). The median survival was 11.4 months for patients treated by palliative resection, and was 9.7 months for patients treated by bypass surgery. These results show that palliative resection can be done safely and effectively in patients with incurable colorectal cancer. We believe this approach improved the quality of the remaining life in these patients.

Cell proliferation and differentiation are regulated by a number of hormones, growth factors. These molecules interact with cellular receptors and communicate with the nucleus of the cell through a network of intracellular signal transduction pathways. A great deal of recent work has defined signal transduction pathways that distinguish malignant from normal cells, and hence identified potential targets for cancer therapy. In colorectal cancer cells, key components of these pathways may be altered by oncogenes through overexpression or mutation, leading to dysregulated cell signaling, inhibition of apoptosis, metastasis, and cell proliferation. The molecular mechanisms and signaling pathways that regulate cell proliferation and survival are receiving considerable attention as potential targets for anticancer strategies. This article was reviewed the role of signal transduction in colorectal cancer, introduce promising molecular targets, and outline therapeutic approaches under development.

BACKGROUND: The optimum surgical treatment for rectal prolapse is controversial, and many different operations have been described. The aim of this study is to evaluate the results of a perineal procedure for the treatment of rectal prolapse. METHODS: Between February 1990 and March 1997, 16 consecutive patients underwent perineal rectosigmoidectomy for a complete rectal prolapse. One patient was lost to follow up. The remaining 15 patients were followed up for an average of 58.4 (9~94) months, and clinical and functional outcomes were evaluated. RESULTS: There were 8 males and 7 females, and ages ranged from 18 to 65 years. The mean prolapse duration was 10.7 (0.25~30) years. There were no postoperative deaths. Two patients developed postoperative complications (one wound infection and the other wound hematoma). Five patients had fecal incontinence prior to surgery. Three of the five patients had improved fecal incontinence after the procedure. There were three recurrences (recurrence rate of 20%): one of them underwent a Delorme operation at our institution and others had no treatment. CONCLUSION: A perineal rectosigmoidectomy is a safe and effective operation for the primary treatment of rectal prolapse and has low mortality and morbidity.
