Colonic diverticular disease is a common condition, affecting 50% of the population aged above 80. In contrast, rectal diverticular disease is a rare condition with very few cases reported, while symptomatic rectal diverticular disease is even rarer. We present a case of a symptomatic large rectal diverticulum presenting with a retrorectal abscess. A 49-year-old Caucasian female was brought to the emergency department complaining of abdominal pain and weakness in the lower limbs. She was found to have obstructive uropathy and unilateral sciatic neuropathy. She rapidly developed acute abdomen and emergency laparotomy revealed a giant purulent rectal diverticulum. The patient underwent exploratory laparotomy and a loop colostomy was made to decompress the colon., Highlights • Colonic diverticular disease is a common condition, affecting 50% of the population aged above 80. • In contrast, rectal diverticular disease is a rare condition with very few cases reported, while symptomatic rectal diverticular disease is even rarer.

There is discrepancy and failure to adhere to current international guidelines for the management of metastatic colorectal cancer (CRC) in hospitals in Greece and Cyprus. The aim of the present document is to provide a consensus on the multidisciplinary management of metastastic CRC, considering both special characteristics of our Healthcare System and international guidelines. Following discussion and online communication among the members of an executive team chosen by the Hellenic Society of Medical Oncology (HeSMO), a consensus for metastastic CRC disease was developed. Statements were subjected to the Delphi methodology on two voting rounds by invited multidisciplinary international experts on CRC. Statements reaching level of agreement by ≥80% were considered as having achieved large consensus, whereas statements reaching 60-80% moderate consensus. One hundred and nine statements were developed. Ninety experts voted for those statements. The median rate of abstain per statement was 18.5% (range: 0-54%). In the end of the process, all statements achieved a large consensus. The importance of centralization, care by a multidisciplinary team, adherence to guidelines, and personalization is emphasized. R0 resection is the only intervention that may offer substantial improvement in the oncological outcomes.

In rectal cancer management, accurate staging by magnetic resonance imaging, neo-adjuvant treatment with the use of radiotherapy, and total mesorectal excision have resulted in remarkable improvement in the oncological outcomes. However, there is substantial discrepancy in the therapeutic approach and failure to adhere to international guidelines among different Greek-Cypriot hospitals. The present guidelines aim to aid the multidisciplinary management of rectal cancer, considering both the local special characteristics of our healthcare system and the international relevant agreements (ESMO, EURECCA). Following background discussion and online communication sessions for feedback among the members of an executive team, a consensus rectal cancer management was obtained. Statements were subjected to the Delphi methodology voting system on two rounds to achieve further consensus by invited multidisciplinary international experts on colorectal cancer. Statements were considered of high, moderate or low consensus if they were voted by ≥80%, 60-80%, or

To evaluate the necessity of metallic stenting of the sphincter of Oddi in malignant obstructive jaundice when the tumor is more than 2 cm from the papilla of Vater.Sixty-seven self-expandable biliary stents were used in 60 patients with extrahepatic lesions of the common hepatic or common bile duct and with the distal margin of the tumor located more than 2 cm from the papilla of Vater. Stents were placed above the papilla in 30 cases (group A) and in another 30 with their distal part protruding into the duodenum (group B).The 30-day mortality was 15%, due to the underlying disease. The stent occlusion rate was 17% after a mean period of 4.3 months. No major complications were noted. Average survival was 132 days for group A and 140 days for group B. In group A, 19 patients survivedor = 90 days and in eight of these, cholangitis occurred at least once. Of 11 patients in group A with survival90 days, only two developed cholangitis. In group B, 13 patients who survivedor = 90 days had no episodes of cholangitis and in 17 with survival90 days, cholangitis occurred in three. There is a statistically significant difference (p0.05) regarding the incidence of cholangitis in favor of group A.In patients with extrahepatic lesions more than 2 cm from the papilla and with a relative poor prognosis (or = 3 months), due to more advanced disease or to a worse general condition, the sphincter of Oddi should also be stented in order to reduce the postprocedural morbidity.
