Background: Transanal dissection of the rectum has been recently introduced for ileal pouch-anal anastomosis (IPAA) in UC showing promising results. Thanks to the precise identification of the rectotomy site the risk of long rectal stump is avoided, and a single stapled anastomosis is performed easily. The aim of this study is to analyze our initial experience of transanal IPAA (Ta-IPAA), considering postoperative complications and medium-term functional outcomes. Methods: Our Center has experienced the transanal approach for proctectomy and IPAA since October 2018. All patients underwent Enhanced Recovery After Surgery (ERAS) protocol. Postoperative complications occurring within 30 days after surgery were taken into consideration. Results: Until March 2019, 8 patients underwent Ta-IPAA. In all cases the laparoscopic approach was performed during the transabdominal phase; abdominal drainage was never used. At the time of the pouch construction a defunctioning ileostomy was created in all patients. Stoma closure was performed in all cases at a median time of 6 months after surgery. Postoperative complications occurred in only one patient, who showed rectal bleeding. There were no cases of anastomotic leakage. Medium-term functional outcomes were determined prospectively by a validated questionnaire (Cleveland Global Quality of Life). Fecal incontinence for liquid or solid stool, restriction in work and social genitourinary and sexual functions were also investigated. Conclusions: In our experience, Ta-IPAA provided good short and medium-term functional results in UC. Background Restorative proctocolectomy is widely adopted in the treatment of ulcerative colitis ,, , as well as in other inflammatory and neoplastic conditions, requiring an ileal pouch-anal anastomosis (IPAA) to reconstruct gastrointestinal continuity to the anus. Conventionally, either the laparoscopic or the open approach can be employed to gain rectal dissection and creation of ileal pouch-anal anastomosis. Pouch-anal anastomosis is usually made using a stapler, leaving a 2 cm rectal cuff in order to preserve continence and to reduce the risk of inflammatory recurrence or dysplasia. The dissection of the last centimeters of the rectum, rectum resection and ileal pouch-anal anastomosis could be demanding from a technical point of view due to narrow pelvic space and cross stapling of the distal part of the rectum is often challenging for surgeons. Transanal total mesorectal excision (TaTME) has been recently described in rectal cancer treatment, with potential technical and oncologic advantages compared to transabdominal approach. The transanal approach for the proctectomy has been described also in IPAA since 2015, showing feasibility and potential technical advantages; some series ,,, and initial comparative studies have been published , , showing a not increased rate of postoperative morbidity, equivalent quality of life and functional results. The aim of our study is to analyze a single centre experience of transanal IPAA (Ta-IPAA), examining e...

Background This review aims to present a consensus for optimal perioperative care in colonic surgery and to provide graded recommendations for items for an evidencedbased enhanced perioperative protocol. Methods Studies were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts. For each item of the perioperative treatment pathway, available English-language literature was examined, reviewed and graded. A consensus recommendation was reached after critical appraisal of the literature by the group. Results For most of the protocol items, recommendations are based on good-quality trials or meta-analyses of goodquality trials (quality of evidence and recommendations according to the GRADE system). Conclusions Based on the evidence available for each item of the multimodal perioperative care pathway, the Enhanced

Improved adherence to the standardized multimodal ERAS protocol is significantly associated with improved clinical outcomes following major colorectal cancer surgery, indicating a dose-response relationship.

High adherence to the ERAS protocol may be associated with improved 5-year cancer-specific survival after colorectal cancer surgery.

Background-Two acyl-coenzyme A:cholesterol acyltransferase (ACAT) genes, ACAT1 and ACAT2, have been identified that encode 2 proteins responsible for intracellular cholesterol esterification. Methods and Results-In this study, immunohistology was used to establish their cellular localization in human liver biopsies. ACAT2 protein expression was confined to hepatocytes, whereas ACAT1 protein was found in Kupffer cells only. Studies with a highly specific ACAT2 inhibitor, pyripyropene A, in microsomal activity assays demonstrated that ACAT2 activity was highly variable among individual human liver samples, whereas ACAT1 activity was more similar in all specimens. ACAT2 provided the major cholesterol-esterifying activity in 3 of 4 human liver samples examined. Conclusions-The data suggest that in diseases in which dysregulation of cholesterol metabolism occurs, such as hypercholesterolemia and atherosclerosis, ACAT2 should be considered a target for prevention and treatment.

Postoperative hyperglycaemia is common among patients with no history of diabetes, even within an enhanced-recovery protocol. Preoperative measurement of HbA1c may identify patients at higher risk of poor glycaemic control and postoperative complications.

Type 2 diabetic patients showed no signs of delayed gastric emptying, suggesting that a carbohydrate-rich drink may be safely administrated 180 min before anaesthesia without risk of hyperglycaemia or aspiration pre-operatively.
