The influence of specific technical maneuvers utilized in the creation of diverting loop-ileostomies on stoma-related morbidity.

PURPOSE: The association between technical maneuvers in fashioning a diverting loop-ileostomy and stoma-related complications remains unclear. Thus, this study aimed to evaluate their relevance to stoma-related morbidity. METHODS: This retrospective multicenter study was designed to collect data from 37 institutions. We evaluated the perioperative outcomes of consecutive patients who underwent surgery to create a diverting loop-ileostomy in 2013. RESULTS: A total of 4137 patients with colorectal disease underwent colorectomy, 279 of whom received an ileostomy. The results of these 279 patients were analyzed. The most common complications were parastomal dermatitis (n = 132) followed by ileus (n = 36), mucocutaneous separation (n = 24), parastomal hernia (n = 16), stoma retraction (n = 15), and stoma prolapse (n = 9). The technical maneuvers used in the creation of ileostomies were heterogeneous and some had a great deal of relevance to the complications. A long distance from the ileocecal valve to the ileostomy was associated with a low risk of stoma retraction and a high risk of ileus. Additionally, the height of the distal limb of the ileostomy significantly affected the incidence of parastomal dermatitis and mucocutaneous separation. CONCLUSIONS: Specific technical maneuvers that are utilized in the creation of diverting loop-ileostomies had a significant influence on the incidence of stoma-related morbidities. Our findings emphasize the possibility of minimizing stoma-related complications with appropriate surgical techniques.

[Damage Control Surgery for Perforation of Colon Cancer].

Perforation due to colon cancer maycause peritonitis and septic shock. In these cases, we maynot be able to rescue the patients in spite of emergencysurgical intervention; in these conditions, owing to limitations of operation time, it is difficult for us to assess the state or extent of the disease and to perform an ideal oncological surgerywith dissection of lymph nodes. To overcome these limitations, we introduce the concept of "damage control surgery" developed in the trauma region to treat perforations of colon cancer. There are 3 steps: first, the perforated intestine is resected and the peritoneal cavityis lavaged to control contamination. Open abdominal management is used as a temporaryabdominal closure; second, sepsis is treated in the ICU; and third, based on the treatment strategydecided upon after consulting a colorectal surgeon and the patient's family, a colostomy, anastomosis, and extra dissection of lymph node are performed before abdominal closure. We report the fatal case of a 92-year-old woman who had developed severe shock to indicate the significance of this strategy.

[A case of unresectable cholangiocellular carcinoma treated with surgery followed by combination chemotherapy].

The patient was a 44-year-old man, who was investigated for lateral abdominal pain and liver dysfunction, and subsequently referred to our department with a diagnosis of unresectable intrahepatic cholangiocellular carcinoma (CCC). Radiological examinations revealed the huge mass in the right lobe of the liver with intrahepatic metastasis in the left lobe. The main tumor was surgically removed, but the metastases were not removed. A month after the operation, a subcutaneous implant reservoir was indwelled for repeated transcatheter hepatic arterial chemo infusion therapy (5-fluorouracil 500 mg/day continuous infusion, day 1-5, and CDDP 10 mg/day, day 1) from the right femoral artery. After 15 courses of home anti-cancer chemotherapy, abdominal CT revealed that the size of intrahepatic metastasis in the left lobe of the liver had not shown growth, whereas other metastitic sites popped up in the caudate lobe, which were free of chemical agent flow. There was no major complication related to the chemotherapy throughout the post-treatment course. Although he maintained a good level of QOL, he refused further chemotherapy due to depression. He died of liver failure 7 months after the operation. In conclusion, volume reduction surgery followed by transcatheter hepatic arterial chemo infusion might be promising as an effective therapy for non resectable CCC.
