    Abstract Introduction: Intravascular papillary endothelial hyperplasia (IPEH), originally described by Pierre Masson in 1923, is a benign vascular lesion characterised by the reactive proliferation of endothelial cells. This tumour typically manifests on the fingers, head, neck, or trunk. However, involvement of other organ systems, including abdominal organs, is possible although exceedingly rare.
    Case presentation: A 57-year-old male patient presented to the emergency department with a 24-h history of recurrent light-headedness. The patient was haemodynamically stable, and physical examination showed no abdominal pain. Digital rectal examination unveiled melena. Initial blood analysis indicated a haemoglobin level of 10.5 g/dL. Comprehensive workup with abdominal computed tomography, upper and lower endoscopy, and gastrointestinal lumen MRI failed to yield significant findings.
    Discussion: On the fourth day of hospitalisation, persistent melena and transfusion of four units of blood triggered a new upper endoscopy. This endoscopy extended to the jejunum, revealing a submucosal lesion measuring 20 mm, situated approximately 40 cm distal to the ligament of Treitz. Due to ongoing intraluminal bleeding with decreased haemoglobin levels, a segmental jejunal resection was performed. Pathological examination confirmed the diagnosis of a completely resected submucosal IPEH.
    Conclusion: IPEH, also known as Masson's tumour, is an uncommon vascular lesion within the intestinal tract, occasionally resulting in persistent haemorrhage. The preferred treatment is total surgical resection, with a low likelihood of recurrence. Currently, postoperative surveillance is not recommended. To the best of our knowledge, no cases of recurrence have been documented for Masson's tumour localised in the gastrointestinal tract in the existing literature.

    Abstract Aim: This paper describes a robotic approach to combined gastrointestinal continuity restoration and complex abdominal wall reconstruction after Hartmann's procedure complicated by large midline and parastomal hernias.
    Methods: A robotic Hartmann reversal is performed, followed by robotic retromuscular abdominal wall reconstruction of all ventral defects with bilateral posterior component separation using the double-docking approach. Surgical steps are thoroughly described, and the accompanying video highlights critical steps of the procedure, anatomical landmarks and technical details relevant to successful completion.
    Results: Complete restoration of the anatomy was achieved with an operative time of 6.5 h. Mobilization occured on day 1, and bowels were opened on day 3. Surgical discharge was possible on day 5. No intra-operative surgical complication occurred and follow-up at 6 months showed no recurrence or mid-term complication.
    Conclusion: Combined minimally invasive reconstruction of the gastrointestinal tract and abdominal wall was feasible using a robotic system. In addition, potential advantages of postoperative rehabilitation and reduced surgical site complications are suggested. Prospective evaluation of the technique is ongoing.

    Abstract Robotics may facilitate the realization of fully minimally invasive right hemicolectomy, including intra-corporeal anastomosis and off-midline extraction, when compared to laparoscopy. Our aim was to compare laparoscopic right hemicolectomy with robotic right hemicolectomy in terms of peri-operative outcomes. MEDLINE was searched for original studies comparing laparoscopic right hemicolectomy with robotic right hemicolectomy in terms of peri-operative outcomes. The systematic review complied with the PRISMA 2020 recommendations. Variables related to patients' demographics, surgical procedures, post-operative recovery and pathological outcomes were collected and qualitatively assessed. Two-hundred and ninety-three publications were screened, 277 were excluded and 16 were retained for qualitative analysis. The majority of included studies were observational and of limited sample size. When the type of anastomosis was left at surgeon's discretion, intra-corporeal anastomosis was favoured in robotic right hemicolectomy (4/4 studies). When compared to laparoscopy, robotics allowed harvesting more lymph nodes (4/15 studies), a lower conversion rate to open surgery (5/14 studies), a shorter time to faeces (2/3 studies) and a shorter length of stay (5/14 studies), at the cost of a longer operative time (13/14 studies). Systematic review of existing studies, which are mostly non-randomized, suggests that robotic surgery may facilitate fully minimally invasive right hemicolectomy, including intra-corporeal anastomosis, and offer improved post-operative recovery.

    Abstract BACKGROUND Amyand hernia is a rare condition described as the presence of the appendix within an inguinal hernia. The clinical presentation of can be atypical, depending on the length of the defect's history and the size of the hernia. As inguinal hernia repair is considered a routine surgical procedure, giant hernias are mostly encountered in countries with limited medical care or with patient rejection of surgical management. CASE REPORT We report a case of a 56-year-old patient with a history of a chronic giant inguinal-scrotal hernia for more than 10 years who presented himself to the Emergency Department with acute pain in the scrotum and fever. Computed tomography revealed a perforated appendicitis located in the inferior part of the scrotum. The patient underwent a surgical procedure with an inguinal and middle laparotomy approach, revealing a full incarceration of the right and traverse colon, terminal ileal loop, and omentum, along with evidence of a perforated appendicitis. Standard appendectomy and direct hernia repair were successfully performed. CONCLUSIONS To the best of our knowledge, this is the first case of a perforated appendicitis within a right giant inguinal hernia described in the modern English-language literature. Rare in our daily practice, giant hernias are a real challenge regarding their surgical management during and after surgery, making this case with a perforated appendicitis even more arduous.

    Abstract RECENT ADVANCES IN FECAL INCONTINENCE TREATMENT. Anal incontinence is a chronic condition that affects nearly 10% of the general population. When anal leakage concerns the stool and is frequent, the impact on the quality of life is very important. Recent advances in non-invasive medical treatments and in operative approaches make it possible to provide for most patients an anorectal comfort compatible with a social life. The three main challenges for the future lie in the organization of screening for this condition which is still taboo and for which patients do not easily confide, in a better selection of patients to offer the most suitable treatments, and therefore a better understanding of the pathophysiological mechanisms; and finally in the establishment of algorithms which prioritize treatments according to their side effects and their effectiveness.

    Abstract Rectovaginal fistula (RVF) occurring during the course of Crohn's disease (CD) constitutes a therapeutic challenge and is characterized by a high rate of recurrence. To optimize the outcome of CD-related RVF repair, the best conditions for correct healing should be obtained. Remission of CD should be achieved with no active proctitis, the perianal CD activity should be minimized, and local septic complications should be controlled. The objective of surgical repair is to close the fistula tract with minimal recurrence and functional disturbance. Several therapeutic strategies exist and the approach should be tailored to the anatomy of the RVF and the quality of the local supporting tissues. Herein, we review the medical and surgical management of CD-related RVF.

    Abstract Two years after a Hartmann's procedure, an 85-year-old woman was admitted at our emergency department with abdominal bloating and severe constipation for 5 days. Abdominal CT showed a large rectal stump mucocele associated with compression of surrounding structures, causing a mechanical ileus and a bilateral pyelocaliceal dilatation. Successful transanal drainage with a rectal catheter allowed rapid recovery.

    Abstract BACKGROUND Desmoid tumor (DT), also known as aggressive fibromatosis or desmoid-type fibromatosis, is a rare disease. It can occur in anyone at any age, and is more likely to appear in female patients. DTs are sometimes associated with familial adenomatous polyposis and rare syndromes such as Gardner syndrome. Arising from specific cells, fibroblasts, they tend to develop in patients with a history of abdominal surgery and rarely produce metastases. CASE REPORT We present a case of a 41-year-old man who was referred for abdominal discomfort with no digestive or general symptoms. An abdominal CT scan revealed a mass in the left hypochondrium, corresponding to an intraperitoneal tumor extending to left colon. Based on MRI, we suspected a gastrointestinal stromal tumor. Colonoscopy showed no intraluminal tumor in the colon. A PET-CT scan revealed tumor hypermetabolism and no metastases. The mass was diagnosed as a DT after percutaneous biopsy. Six weeks after diagnosis and as the tumor continued increasing despite pharmacological treatment, the patient underwent surgical pancreatic tail resection with splenectomy and left colonic segmentectomy. Histological examination revealed a 7.047-g DT with severe infiltration of pancreatic parenchyma and transmural colic barrier, with no high-grade differentiation and negative resection margins. The postoperative recovery was uneventful, and we proposed surveillance with MRI. CONCLUSIONS The DT was surgically removed and patient remains under MRI surveillance. Other reported management approaches consist of radiotherapy, tyrosine kinase inhibitors, anti-hormonal therapies/non-steroidal anti-inflammatory drugs, chemotherapy, or close surveillance only. This is, to our knowledge, the largest and heaviest DT reported in the modern literature.
