Anorectal melanoma: systematic review of the current literature of an aggressive type of melanoma.

Anorectal melanoma (ARM) is a rare malignancy often associated with a poor prognosis due to its late diagnosis and aggressive biological behavior. This review aims to comprehensively investigate ARM's diagnosis, management, and treatment, emphasizing its clinical characteristics, laboratory findings, and implications for patient prognosis. A systematic literature search was conducted in PubMed, Embase, and Cochrane CENTRAL databases from inception to 1 July 2024.

Topical metronidazole after haemorrhoidectomy to reduce postoperative pain: a systematic review.

Excisional haemorrhoidectomy is the gold standard for operating haemorrhoids, but it is accompanied by a significant problem: postoperative pain. Several strategies have been adopted to minimize this condition. Oral metronidazole has been proven to reduce postoperative pain but with some complications.

Indocyanine Green Tattooing During Colonoscopy as a Guide to Laparoscopic Colorectal Cancer Surgery: A Literature Review.

Background: Endoscopic tattooing of colorectal lesions has been performed employing several markers. The indocyanine green (ICG) that uses near infrared fluorescence technology, has been recently adopted in laparoscopic colorectal cancer surgery. This study aims to systematically review the international literature to validate the ICG in laparoscopic colorectal surgery, in order to include the ICG in the therapeutic protocol.

Sizzling Fat-Curative Endoscopic Resection of a Giant Lipoma Causing Colo-Colic Intussusception.

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.

Transperineal excision of malignant peripheral nerve sheath tumors of the ischiorectal fossa: Case report of a rare tumor in a frequently forgotten anatomical region.

Introduction And Importance: Malignant peripheral nerve sheath tumor is an aggressive tumor that arises from peripheral nerves. Frequently associated with neurofibromatosis, its common localization is in the extremities, trunk (with paravertebral regions), neck and head. Some cases have been found in the pelvis or uterus.

Collagen treatment of complex anorectal fistula: 3 years follow-up.

Fistula in ano is a common anorectal disease in adults. Currently, surgery remains the definitive therapeutic approach, but in some cases, it can lead to serious complications as faecal or gas incontinence. Therefore, sphincter sparing treatments should be considered for complex fistulas.

Pesky Pesce: A Forgettable Fish Dinner with a Late Surprise, a Perianal Abscess.

Clinical presentation after ingestion of foreign body is a common finding in surgical practice. Perianal sepsis due to a foreign body is, usually, secondary to introduction via the trans-anal route. The case here reported is extremely rare since an ingested fishbone passed asymptomatically through most of the gastrointestinal tract, with resultant late-onset ischiorectal abscess.

Mesenchymal Stem Cells for Cryptoglandular Anal Fistula: Current State of Art.

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.

Coincidental or Causal? Concurrence of Colorectal Carcinoma with Primary Breast Cancer.

Multiple primary malignant neoplasms (MPMN) represent the occurrence of a second malignancy in the same patient within 6 months after the detection of first primary (synchronous) tumor, or > 6 months after primary detection (metachronous). We present a case of a patient treated for carcinoma of the breast who developed a metachronous primary malignancy in the colorectal tract. These tumors were histologically different with distinct immune-histochemical parameters.

Expression and Clinical Utility of Transcription Factors Involved in Epithelial-Mesenchymal Transition during Thyroid Cancer Progression.

The transcription factors involved in epithelial-mesenchymal transition (EMT-TFs) silence the genes expressed in epithelial cells (e.g., E-cadherin) while inducing those typical of mesenchymal cells (e.

Self-Mechanical Anal Dilatation: A Simple Trick to Minimize Postoperative Pain and Stenosis Following Hemorrhoidectomy With Radiofrequency.

Hemorrhoidectomy is still the most effective surgical treatment for hemorrhoidal disease, but it is, however, associated with complications such as pain and stenosis. We proposed to break the "vicious circle" of "pain-sphincteric spasm-stenosis-pain" with the postoperative use of self-mechanical anal dilation. We retrospectively analyzed patients with hemorrhoidal disease presenting with a minimum of piles of three quadrants, treated with radiofrequency hemorrhoidectomy between January 2018 and December 2019.

Thyroid Nodule Characterization: How to Assess the Malignancy Risk. Update of the Literature.

Ultrasound (US) is the first imaging modality for thyroid parenchyma evaluation. In the last decades, the role of ultrasound has been improved with the introduction of new US software, such as contrast-enhanced ultrasound (CEUS) and US-elastography (USE). USE is nowadays recognized as an essential part of the multiparametric ultrasound (MPUS) examination, in particular for the indeterminate thyroid nodule with possible fine-needle aspiration cytology (FNAC) number reduction; even if further and larger studies are needed to validate it.

Anal excision of perianal fibroadenoma: Expect the unexpected.

Breast fibroadenomas are a common benign tumour in women that may need to be surgically excised. A mammary-like fibroadenoma can exceptionally be found in the pathological report after an anal polyp removal. A 60-year-old woman presented with huge anal polyp of 25 mm.

A case report of a colouterine fistula treatment: when the patient chooses the steeplechase.

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: "Mucosectomy or Not Only Mucosectomy, This Is the Problem".

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.

Difficult biliary stones in the elderly: Endoscopic retrograde cholangiography - A single surgical tertiary centre experience with follow-up.

Background: Pancreaticobiliary diseases and choledocholithiasis are common in elderly patients. Endoscopic treatment of biliary stones represents a well-established mini-invasive technique. However, limited data are available regarding the treatment of 'difficult' biliary stones, especially in the elderly population.

Dermatome Mapping Test in the analysis of anatomo-clinical correlations after inguinal hernia repair.

Background: Nerve identification is recommended in inguinal hernia repair to reduce or avoid postoperative pain. The aim of this prospective observational study was to identify nerve prevalence and find a correlation between neuroanatomy and chronic neuropathic postoperative inguinal pain (CPIP) after 6 months.

Material: A total of 115 patients, who underwent inguinal hernia mesh repair (Lichtenstein tension-free mesh repair) between July 2018 and January 2019, were included in this prospective observational study.

Improvement in Hemorrhoidal Disease Surgery Outcomes Using a New Anatomical/Clinical-Therapeutic Classification (A/CTC).

 The introduction and diffusion of new techniques for hemorrhoidal surgery have made it clear how much Goligher classification is inadequate in the modern times, lacking in any correlation between anatomical and clinical features to a surgical procedure. The aim of the study was to evaluate if the application of a new classification of hemorrhoidal diseases might lead to an improvement in the postoperative surgical outcomes.  From January 2014 to December 2015, all patients undergoing surgery for hemorrhoidal disease were enrolled.
