Isoperistaltic versus antiperistaltic ileocolic anastomosis. Does it really matter? Results from a randomised clinical trial (ISOVANTI)
BackgroundRight hemicolectomy is a very common surgery. Many studies compare different options for laparoscopic ileocolic anastomoses: intra- or extracorporeal; handsewn or stapled; side-to-side or end-to-side. However, there are no studies about the influence that peristalsis could have on this anastomosis. The aim of this study is to compare safety and feasibility of isoperistaltic and antiperistaltic anastomosis in terms of postoperative morbidity and mortality between both groups. The secondary endpoint is to compare long-term functional outcomes (chronic diarrhoea) and quality of life (GIQLI questionnaire) after a 1-year follow-up period.MethodsA double-blind, randomised, prospective trial in patients undergoing scheduled surgery for right colon cancer with laparoscopic right hemicolectomy and isoperistaltic (ISO) or antiperistaltic (ANTI) ileocolic anastomoses.ResultsHundred and eight patients were included in the study. Patients were randomised either to isoperistaltic or antiperistaltic configuration (54 ISO/ANTI). No significant differences in baseline variables were found. No differences in surgical time (130 [120–150] min ISO vs. 140 [127–160] ANTI, p = 0.481), nor in anastomotic time (19 [17–22] vs. 20 [16–25], p = 0.207) and nor in postoperative complications: 37.0% ISO versus 40.7% ANTI, (p = 0.693) were found. There were no differences in postoperative ileus (p = 0.112) nor in anastomotic leakage (3.7% vs. 5.56%, p = 1.00). Differences in “time to first flatus” and “time to first deposition” were found in favour of the antiperistaltic group (p = 0.004 and p = 0.017). Anastomotic configuration did not influence hospital stay (3 days [2–6] isoperistaltic vs. 3 [2–4] antiperistaltic, p = 0.236). During follow-up, there were no differences between the two groups at 1, 6 and 12 months (p = 0.154, p = 0.498 and p = 0.683), nor in chronic diarrhoea rates in GIQLI scores (24% ISO vs. 31.4% ANTI, p = 0.541).ConclusionsThe isoperistaltic and antiperistaltic ileocolic anastomosis present similar results in terms of performance, safety and functionality. However, further studies must be carried out in order to assess relationship between postoperative ileus and anastomosis configuration.Trial registrationRandomised Clinical trial (Identifier: NCT02309931).

Whistleblowers : Chelsea Manning, Edward Snowden and others
Whistleblowers are both celebrated and reviled. They expose illegal or unconscionable actions by a government official or organization, the dangerous practices or financial fraud of a corporation, or the perjury of a high-profile witness. The reasons that motivate whistleblowers are as diverse as the crimes and misdeeds they expose. Through articles written at the time of events, this book introduces readers to some of the most famous whistleblowers in recent history. These include Mark Felt, aka \"Deep Throat,\" whose information helped uncover the Watergate scandal; Chelsea Manning, who, as Bradley Manning, shared classified documents revealing unsavory, untruthful, and potentially illegal activity by the United States government in the Middle East; and Grigory Rodchenkov, the doctor who exposed Russia's state-sponsored doping program.

Technical considerations depending on the level of vascular ligation in laparoscopic rectal resection
AimIn addition to ischemia there is also anastomotic ends tension proven to be a risk factor for anastomotic leak. HT vascular ligation is accepted as a rule, in attempt to achieve tension-free anastomosis. LT is a preferred option, based on the more accurate preservation of proximal intestinal segment microperfusion and lower risk of damage to the hypogastric plexus. The aim of this study is evaluation of comparative indicators in high tie (HT) and low tie (LT) laparoscopic rectal resections.MethodsA prospective nonrandomized comparative cohort study of patients in our department with cancer of the rectum in clinical stage I–III, operated on in laparoscopic approach over a 6-years period.ResultsFor the period 2015–2020, a number of 208 laparoscopic surgeries have been done for rectal cancer. Patients were divided into three groups—group A with HT vascular ligation 116 pts. (69%), group B—53 pts. (25%), underwent low ligation—LT and group C—39pts. (19%) low tie plus lymph node dissection of the apical LN group (LT-appic LND). The distribution was made without randomization, based on the operators’ expertise. Anastomotic leaks were 3.8% in group A, 3.0% in group B and 2.9% in group C (p > 0.05) with no significance difference. There is no significant difference in the number of lymph nodes obtained in group A and group B, while in group C the number of the harvested lymph nodes was higher (p < 0.05). The indicators for intestinal / defecation dysfunction, as well as for urinary/sexual dysfunction, according to our data, are significantly more favorable in patients with LT, in contrast to the other two groups.ConclusionHT vascular ligation attempts to achieve tension-free anastomosis and more harvested lymph nodes. However, LT could be a preferred option, based on the lack of significant evidence for a difference in specific oncological survival and due to more accurate preservation of proximal intestinal segment microperfusion to prevent anastomosis dehiscence, also for its lower risk of damage to the hypogastric plexus. Splenic flexure mobilization provides elongation of the proximal intestinal segment, but has no proven effect on anastomotic leakage incidence. It increases surgical duration and is in fact necessary in up to 30% of the cases. At the present moment there is no precise data whether LT has an advantage in terms of prevention of autonomic nervous and urogenital dysfunction. New prospective randomized and highly probative studies are needed to standardize the procedures in specific clinical situations.

Edward Snowden
In June 2013, the news organization The Guardian first published articles revealing the shocking revelations that the National Security Agency (NSA) was conducting mass surveillance on all American citizens in secretive bulk-data collection programs. Hundreds of thousands of top-secret documents were leaked from the NSA by a computer programmer named Edward Snowden. This enlightening biography examines the life of Edward Snowden, his reasons for leaking classified documents, his ongoing controversy as a whistleblower, and the revelations and changes in data collection laws that resulted from the massive disclosure.

Endoscopic or combined management of post-surgical biliary leaks: a two-center recent experience
Background and AimsPost-surgical biliary leaks (PSBL) are one of the most prevalent and significant adverse events emerging after liver or biliary tract surgeries. Endoscopic retrograde cholangiopancreatography (ERCP) alone or combined with another approach (Rendez Vous) as treatment of PSBL obtains optimal outcomes due to the possibility of modifying the resistances in the biliary tree.MethodsA retrospective double-center study was conducted in two tertiary centers. Consecutive patients who underwent at least one attempt of PSBL correction by ERCP or Rendez Vous procedure between January 2018 and August 2023 were included. The primary outcome was overall endoscopic clinical success. In contrast, the secondary outcomes were hospital stay exceeding five days and endoscopic clinical success with the first endoscopic procedure at the tertiary center. Both univariate and multivariate analyses were used to assess outcomes.Results65 patients were included. Patients with one or multiple) leaks had more possibility to achieve the endoscopic clinical success compared to those affected by the association of leaks and stricture (96% vs 67%, p value 0.005). Leaks occurring in the main biliary duct had less probability (67%) to achieve the overall endoscopic clinical success compared to those in the end-to-end anastomosis (90%), in the resection plane or biliary stump (96%) or first or secondary order biliary branches (100%, p value 0.038). A leak-bridging stent positioning had more probability of achieving the endoscopic clinical success than a not leak-bridging stent (91% vs 53%, p value 0.005).ConclusionsERCP and Rendez Vous procedures are safe and effective for treating PSBL, regardless of the type of preceding surgery, even if technical or clinical success was not achieved on the first attempt. A stent should be placed, if feasible, leak-bridging to enhance treatment efficacy.

Emerging Trends in the Etiology, Prevention, and Treatment of Gastrointestinal Anastomotic Leakage
Anastomotic leaks represent one of the most alarming complications following any gastrointestinal anastomosis due to the substantial effects on post-operative morbidity and mortality of the patient with long-lasting effects on the functional and oncologic outcomes. There is a lack of consensus related to the definition of an anastomotic leak, with a variety of options for prevention and management. A number of patient-related and technical risk factors have been found to be associated with the development of an anastomotic leak and have inspired the development of various preventative measures and technologies. The International Multispecialty Anastomotic Leak Global Improvement Exchange group was convened to establish a consensus on the definition of an anastomotic leak as well as to discuss the various diagnostic, preventative, and management measures currently available.

Efficacy and safety of anastomotic leak testing in gastric cancer: a randomized controlled trial
BackgroundAnastomosis-related complications such as bleeding, leakage, and strictures, continue to be serious complications of gastric cancer surgery. Presently, these complications have yet to be reliably prevented. Here we design a comprehensive leak testing procedure which combines gastroscopy, air, and methylene blue (GAM) leak testing. We aimed to evaluated the efficacy and safety of the GAM procedure in patients with gastric cancer.MethodsPatients aged 18–85 years without an unresectable factor as confirmed via CT were enrolled in a prospective randomized clinical trial at a tertiary referral teaching hospital and were randomly assigned to two groups: intraoperative leak testing group (IOLT) and no intraoperative leak testing group (NIOLT). The primary endpoint was the incidence of postoperative anastomosis-related complications in the two groups.Results148 patients were initially randomly assigned to the IOLT group (n = 74) and to the NIOLT group (n = 74) between September 2018 and September 2022. After exclusions, 70 remained in the IOLT group and 68 in the NIOLT group. In the IOLT group, 5 patients (7.1%) were found to have anastomotic defects intraoperatively, which included anastomotic discontinuity, bleeding, and strictures. The NIOLT group had a higher incidence of postoperative anastomotic leakage compared to the IOLT group: 4 patients (5.8%) vs 0 patients (0%), respectively. No GAM-related complications were observed.ConclusionThe GAM procedure is an intraoperative leak test that can be performed safely and efficiently after a laparoscopic total gastrectomy. GAM anastomotic leak testing may effectively prevent technical defect-related anastomotic complications in patients with gastric cancer who undergo a gastrectomy.Trial registration: Clinical Trials.gov Identifier: NCT04292496.
