Evidence has been presented to suggest that the patient with an obstructed carcinoma of the colon may have a more malignant form of the disease independent of lymph node status or tumor encirclement of the bowel. Rate of tumor growth is never consistent in patients with this disease. Patients who develop colon obstruction early in the course of the disease seem to have more aggressive tumors with rapid growth and a much poorer long-term prognosis. Perforations frequently accompany obstructions of the colon. Patients in this group have a dismal prognosis. Individuals with obstructed carcinoma of the colon have a higher operative mortality and morbidity and a shorter long-term survival. The higher operative mortality and morbidity may depend entirely on the choice of operative procedures. Tumor location affects prognosis. Obstructing tumors in the left colon have a more favorable prognosis than those in the right colon. Obstructing right colon tumors have a much poorer survival (three times worse) than nonobstructing carcinomas of the right colon. Obstructing tumors in the rectum have a very poor prognosis. Evidence exists that resection of the tumor without preliminary proximal decompression may reduce hospital mortality and morbidity and increase long-term survival. In selected cases, primary resection can be done as safely as staged operative procedures. Primary anastomosis with resection of the left colon carries a higher operative mortality because of anastomotic leaks. Resection without anastomosis is much safer. Primary resection with anastomosis is the procedure of choice in obstructing lesions of the right colon. This has a lower operative mortality and morbidity than a staged procedure. This primary resection with anastomosis is certainly as safe as an ileotransverse colostomy. It is important not to abandon the time-honored surgical principle of never suturing obstructed bowel. Primary resection without anastomosis confirms this surgical principle. Meticulous preoperative and postoperative care employing physiological monitoring, multiple antibiotics, total parenteral hyperalimentation, and respiratory and circulatory support will further reduce the hospital mortality and morbidity. Patients who initially appear to be obstructed on barium enema, but who in truth are only partially obstructed, can be properly managed so that an elective primary resection with anastomosis can be done with the same operative mortality and morbidity as in other elective colon cancer patients.

Clinical and surgical situation and problems of the blood purification as an artificial renal supports, including hemodialysis, hemofiltration and hemoadsorption, were studied especially fields related with treatment of acute renal failure (ARF), surgeries in the patients treated with chronic hemodialysis and supportive care for the cadaveric renal transplantation. ARF: Our experimental data using septic rats showed that hemoadsorption activated host's reticuloendothelial function and consequently increased survival rate of septic rats. Clinically, similar results were observed by the combination of hemodialysis and hemoadsorption, and the survival rate of ARF with multiple organ failure increased to 68% (21 out of 31 cases) from 30% (8 out of 27) in the patients treated with only hemodialysis. Surgery in the chronic hemodialysis patients: One hundred twenty two operations have been done among the patients treated with chronic hemodialysis in our clinic. However, 15 in emergency cases were died within post operative period. There is no operative death in scheduled operations including total esophagectomy and simultanous radical operation of gall bladder cancer and colon cancer. Pre- and post operative supportive management with immunopotentiator, opsonic protein, coagulative factors and intravenous hyperalimentation with branched chain rich amino acid solution should be added routinely to artificial renal supports in pre- and post operative period. Cadaveric renal transplantation: Eighty-seven percent of cadaveric renal transplantation in our clinic were needed artificial renal support in early phase of post transplantation period because of insufficient renal function by acute tubular necrosis. Necessity of the acceptance of brain death category in Japan is strongly pleaded.

Cancer surgery is a major challenge for patients to develop immune depression in postoperative period. Several cytokines can depress immune cell subpopulations. Increased cytokine response after surgery is assumed to arise mainly from lipooxygenase pathway acting on membrane arachidonic acid. Therefore; investigators focused their efforts to alter the membrane fatty acid profile by changing the nutritional regimen with epsilon-3 fatty acid supplementation and encouraging results were obtained after surgery. Despite the theoretical and clinical advantage of enteral nutrition many surgeons remain committed to parenteral nutrition for feeding of patients due to maintain bowel rest and fear of anastomosis leakage at the postoperative period. Several studies investigating role of the postoperative immunonutrition reported that beneficial immunological changes were associated with reduction of infectious complications. Interestingly; these findings were observed at least five days after the surgery in which the highest incidence of complications was seen. In this prospective study including 42 patients eligible for curative gastric or colon cancer surgery; we investigated the beneficial effect of enteral immunonutrition (EEN) compared to total parenteral hyperalimentation (TPN) beginning from the preoperative period. Cortisol and CRP levels as stress parameters significantly increased one day after surgery in both groups but they rapidly returned to (on POD1) preoperative baseline level in EEN group whereas these values remained high in the TPN group. Additionally a significant decrease in natural killer (NK) cells and CD8+ levels were observed in both groups. However they recovered on POD3 in EEN group and on POD6 in TPN group. CD4+ subset remained almost same as preoperative value in the TPN group whereas it increased from (%) 40.14 to 46.40, 51.29 and 54.7 on PO 6th hr, POD3 and POD6 in the EEN group. Our findings suggest that preoperative nutrition via the enteral route provided better regulation of postoperative immune system restoration than parenteral nutrition. On the basis of our findings we recommend enteral immunonutrition to be started at the preoperative period rather than postoperatively before a major operation whenever the enteral route is feasible.

We describe a case of ulcerative colitis (UC) where clinical symptoms began abruptly within a few weeks after colon resection. The patient, a 44-year-old woman, was first referred to our hospital for the treatment of colon cancer. During the past several years, she had not had any inflammatory bowel disease-like clinical symptoms, such as frequent diarrhea or abdominal discomfort. Before the operation, both macroscopic and microscopic examination revealed that no remarkable inflammatory change was associated with the cancer in any area of her colon. At 10 days after the operation, she started to complain of frequent watery diarrhea. Two weeks after the operation, she was readmitted to our hospital because of frequent bloody diarrhea, fever, and abdominal discomfort. Based on endoscopic and histological examinations, she was diagnosed as having severe UC and was treated with hyperalimentation, predonisolone, mesalazine, and granulocyte apheresis. However, she did not respond to this combination therapy. At 45 days after the first operation, owing to sudden onset hemorrhagic shock, she underwent a second colectomy. The resected specimen of the entire colon showed severe pancolitis, and histological examination revealed severe inflammatory changes in the lamina propria together with crypt distortion, all of which were consistent with UC.
