Background: French laws governing end-of-life medical practices forbid euthanasia and affirm patients' right to deep and continuous sedation until death. Cultural traditions and disparities in health care provision, as in overseas France, could limit the enforcement of such laws and modify end-of-life medical practices.

Aim: This research aims to describe end-of-life medical decisions in overseas France and to compare with those described in mainland France.

Article Synopsis
  • The study looked at patients with diverticular disease (DD) and how their bowel movements, like constipation and diarrhea, relate to the seriousness of their condition.
  • Researchers measured the severity using different tools and checked how changes in bowel habits might predict future health problems.
  • They found that people with worse constipation or diarrhea had more severe DD and were more likely to develop a serious illness called acute diverticulitis over three years.

Article Synopsis
  • The French National Authority for Health (HAS) has released new guidelines for patient blood management (PBM) during surgeries, focusing on three key areas: optimizing red blood cell count, minimizing blood loss, and managing anemia tolerance.
  • Preoperative recommendations include identifying anemia and iron deficiency early, especially for surgeries with a higher risk of bleeding.
  • Intraoperative strategies involve using tranexamic acid and certain surgical techniques to control bleeding, while postoperative guidance emphasizes reducing blood sampling and monitoring for anemia to determine if treatments like intravenous iron are needed.

Giant colonic lipomas, tumors that infrequently occur in the gastrointestinal tract, can manifest as bleeding, abdominal pain and, in few cases, obstruction with intussusception. Surgery is usually the treatment of choice. We report the case of a 78 years-old woman with abdominal pain, constipation, and bleeding due to a giant lipoma of the sigmoid colon causing intussusception.

Article Synopsis
  • Diverticular disease (DD) management is complicated by an unclear understanding of its causes, highlighting the need for better treatments.
  • Research found that DD patients exhibit low antioxidant levels and increased markers related to oxidative stress and inflammation, suggesting a link between these markers and the disease's severity.
  • This study indicates that circulating biomarkers could be crucial for tracking DD progression and developing new treatments, such as antioxidant supplements.

Article Synopsis
  • A study examined the occurrence and effects of segmental colitis linked to diverticulosis (SCAD) in patients with newly diagnosed diverticulosis over three years, involving 2,215 patients.
  • Out of these patients, 44 were diagnosed with SCAD, resulting in a prevalence rate of 1.99%, with most patients being around 64.5 years old.
  • While SCAD often has mild effects, types B and D of the condition were related to more severe symptoms and poorer outcomes, such as higher steroid use and lesser chances of complete recovery.

Article Synopsis
  • A novel endoluminal device called the Disposable Rigid Scope Introducer (DRSI) has been developed to assess the integrity of colorectal anastomoses during surgery, enhancing evaluation techniques beyond basic methods.
  • The DRSI enables visualization of tissue perfusion using indocyanine green (ICG) fluoroangiography and is compatible with standard laparoscopic cameras, facilitating intraoperative assessments.
  • In a study with 16 patients, the DRSI effectively detected complications such as anastomotic bleeding, contributing to decisions on surgical procedures and showing promise for reducing postoperative risks; further research is needed to confirm its potential benefits.

Non-alcoholic fatty liver disease (NAFLD) represents a predominant hepatopathy that is rapidly becoming the most common cause of hepatocellular carcinoma worldwide. The close association with metabolic syndrome's extrahepatic components has suggested the nature of the systemic metabolic-related disorder based on the interplay between genetic, nutritional, and environmental factors, creating a complex network of yet-unclarified pathogenetic mechanisms in which the role of insulin resistance (IR) could be crucial. This review detailed the clinical and pathogenetic evidence involved in the NAFLD-IR relationship, presenting both the classic and more innovative models.

In recent years, the role of gastric and duodenal microbiota has acquired increasing importance in the homeostasis of the host, although, to date, most evidence concern the faecal microbiota. Indeed, the gastric, and duodenal microbiota are challenging to study, due to gastric acid, bile, digestive enzymes, and rapid transit time. Specifically, the gastric acid environment may influence their bacterial composition since the acid barrier protects against orally ingested microorganisms and leads to their inactivation before reaching the intestine.

Anal fistula is a common disease that needs surgical treatment to be resolved. Despite a variety of surgical options, the major problem is still to cure complex fistulas without any recurrence in the long-term follow-up but, at the same time, to avoid an impairment of continence. In recent years, one solution has been the application of mesenchymal stem cells derived from adipose tissue, especially in association with other treatments, such as the use of fibrin glue or the previous application of a seton.

Objectives: Pain and fear of colonoscopy are inter-related; they make the colonoscopy experience unpleasant and impede adherence to colorectal cancer screening and prevention campaigns. According to previous research, fear and pain have been found to depend on patients' maladaptive cognitions and exaggerated emotional responses. The present study investigated whether emotional processing difficulties predicted colonoscopy pain and the associated catastrophising thoughts.

Colouterine fistula is a rare disease that is primarily treated using surgical approaches. Although invasive surgery is controversial in terms of techniques and results, minimally invasive endoscopic treatments have not been widely described. However, because it is rare for these fistulas to close spontaneously, surgical treatment is often mandatory.

Stapled hemorrhoidopexy was originally defined as a rectal mucosectomy. The aims of our retrospective, single-center study were to demonstrate if the excised specimen comprises only the mucosa or more wall rectal layers and if the latter excision should be considered a technical mistake with an increase in complications. We histopathologically analyzed surgical samples from patients who underwent stapled hemorrhoidopexy performed between 2014 and 2019.
