Purpose: Symptomatic rectocele results in obstructed defecation and constipation. Surgical repair may provide symptomatic relief. A variety of surgical procedures have been used in the rectocele repair to enhance anatomical and functional results and to improve long-term outcomes. Methods: In this prospective study, we treated 25 selected women suffering from simple symptomatic rectocele with transperineal repair using porcine dermal acellular collagen matrix Biomesh (Permacol®). Watson score and SF-36 questionnaire were used to evaluate postoperative outcomes and quality of life.

Abstract
BACKGROUND:
In recent years, stapled transanal resection (STARR) has been adopted worldwide with convincing short-term results. However, due to the high recurrence rate and some major complications after STARR, there is still controversy about when the procedure is indicated. The aim of this study was to assess the safety, efficacy and feasibility of STARR performed with a new dedicated device for tailored transanal stapled surgery.

Aim: The management of haemorrhoids has changed significantly in the last two decades as a result of new insights into their pathophysiology and the availability of new surgical devices. The aim of this survey was to evaluate changes in the management of haemorrhoids in Italy over the last 17 years. Method: An electronic database which recorded details of management relating to the severity of haemorrhoids between 2000 and 2016 was obtained from 18 of 34 colorectal surgeons who were invited to participate.

Background: Gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal tumours in the digestive tract. The duodenal GIST (dGIST) is the rarest subtype, representing only 4–5% of all GIST, but up to 21% of the resected ones. The diagnostic and therapeutic management of dGIST may be difficult due to the rarity of this tumor, its anatomical location, and the clinical behavior that often mimic a variety of conditions; moreover, there is lack of consent for their treatment.

Background: Primary biliary cholangitis is an autoimmune disease affecting the interlobular bile ducts. Limited information is available on its epidemiology and treatment in Italy. Aims: To describe primary biliary cholangitis epidemiology and investigate treatment patterns for Italian patients with this disease. Methods: Electronic medical records from 900 general practitioners (part of the QuintilesIMS™ Longitudinal Patient Databases) were examined. Demographics were compared with those from the Italian National Institute of Statistics dataset.

AIM: To perform a systematic review and meta-analysis on platelet-to-lymphocyte ratio (PLR) as a risk factor for post-transplant hepatocellular cancer (HCC) recurrence. METHODS: A systematic literature search was performed using PubMed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria: (1) studies comparing pre-transplant low vs high PLR values; (2) studies reporting post-transplant recurrence rates; and (3) if more than one study was reported by the same institute, only the most recent was included.

AIM To perform a systematic review and meta-analysis on donor-to-recipient gender mismatch as a risk factor for post-transplant graft loss. METHODS A systematic literature search was performed using PubMed, Cochrane Library database and EMBASE. The primary outcome was graft loss after liver transplantation. Odds ratios and 95% confidence intervals were calculated to compare the pooled data between groups with different donor-to-recipient gender matches.

Donor steatosis represents a well-known risk factor for primary non-function, early allograft dysfunction, and biliary complications after liver transplantation (LT). Recently, machine perfusion (MP) technology has been implemented in the clinical practice, with the primary intent to assess the graft quality and to optimize the organ selection process. A limited number of articles has been published specifically investigated the role of MP in steatotic livers, with few of them looking at the role of hypothermic MP.

Prognosticating outcomes in liver transplant (LT) for hepatocellular carcinoma (HCC) continues to challenge the field. Although Milan Criteria (MC) generalized the practice of LT for HCC and improved outcomes, its predictive character has degraded with increasing candidate and oncological heterogeneity. We sought to validate and recalibrate a previously developed, preoperatively calculated, continuous risk score, the Hazard Associated with Liver Transplantation for Hepatocellular Carcinoma (HALTHCC), in an international cohort.
