ABSTRACT
<p><b>OBJECTIVE</b>To discuss surgical treatment of right colon carcinoma of hepatic flexure invading the duodenum.</p><p><b>METHODS</b>Sixty-five patients with right colon carcinoma of hepatic flexure invading the duodenum, treated in our department from 1987 to 2007, were included in this study. Their clinicopathological data were retrospectively reviewed and analyzed. All the cases were divided into three types (local invasion, regional invasion, and cancer with internal fistula) according to duodenal defect, including local invasion (< 2.0 cm), wide invasion (> 2.0 cm) and the presence of internal fistula.</p><p><b>RESULTS</b>25 patients with local invasion underwent en bloc resection of the duodenal wall. Pedicled ileal flap was used to cover the large duodenal defect measuring 2.0 - 3.0 cm in 5 patients. Dudenojejunostomy was used to reconstruct the large defect measuring more than 5 cm in 3 patients. Conservative resection of right-sided colon was performed in 18 patients with wide invasion. 4 patients underwent pancreaticoduodenectomy combined with right hemicolectomy for colon cancer involving the pancreatic head. 10 underwent duodenal diverticularization. One patient with anastomotic leakage healed within 3 weeks. Other patients were cured without postoperative complications. The total 3-year and 5-year survival rates after surgery were 53.8% and 9.2%, respectively.</p><p><b>CONCLUSION</b>The surgical procedure to be performed is usually decided according to the cancer location, extent, and duodenal defect and invasion, which are important for prolonging life time, improving of quality of life and prognosis in these patients.</p>

Objective To summarize the diagnosis and surgical treatment for intractable constipation caused by adult dolichocolon.Methods Clinical data of 82 adult dolichocolon cases suffering from intractable constipation were analyzed retrospectively.Results Of the 82 patients,intractable constipation were found in 66 patients(80%),abdominalgia,abdominal distension in 28 patients(34%) and constipation alternatively with diarrhea in 16 patients(19%).Diagnosis was established in 74 patients by barium enema while 8 during the emergency operation.Dolichocolon was divided into 3 types as type Ⅰ in 35 cases,type Ⅱ in 19 and type Ⅲ in 28,in which there were 18 cases of total dolichocolon syndrome. Surgery performed including sigmoidectomy(32 patients),right hemicolectomy(3 patients),right hemicolon and transvers colon resection(4 patients),left side of transvers colon and splenic flexure colon resection(4 patients),descending colon and sigmoid colon resection(15 patients),transvers,descending and sigmoid colon resection(6 patients),pancolectomy with anastomosis of terminal ileum and upper rectum (18 patients).There were no severe postoperative complications such as anastomotic leakage and the recovery was uneventful in all 82 patients.The curative effect was graded as well and up in all 72 cases followed up from 3 months to 4 years,with a follow-up rate of 88%(72/82).Conclusion A history of intractable constipation and barium enema are the mainstay for the diagnosis of dolichocolon,and operation is the effective treatment for intractable constipation caused by adult dolichocolon.
