Anal melanoma: a clinical challenge without therapeutic consensus.

Anal melanoma is a rare malignancy, accounting for 0.4% to 1.6% of all melanomas.

Fulminant amoebic colitis: a challenging diagnosis for the surgeon.

Fulminant amoebic colitis is a rare complication of amoebiasis that carries a high mortality rate. Its diagnosis is challenging and requires a high index of suspicion, and its early recognition is a priority to provide timely medical and surgical treatment. We present the case of a male patient who came to the emergency department with unspecific clinical presentation of abdominal pain, systemic inflammatory response and imaging study showing intestinal perforation of the right colon.

LIFT procedure: postoperative outcomes, risk factors for fistula recurrence and continence impairment.

Ligation of the intersphincteric fistula tract has been recently employed as definitive treatment of anal fistulas. However, it carries a potential risk of continence impairment, fistula recurrence, and repeated operations. This study aimed to assess postoperative outcomes related to this procedure and evaluate the potential influence of preoperative and intraoperative features.

An uncommon case of right hepatic duct entering cystic duct associated to multiple complications of biliary tract disease: acute pancreatitis, hepatolithiasis, acute cholecystitis and hepatic abscess.

Anatomical variations of the biliary tree pose diagnostic and treatment challenges. While most are harmless and often discovered incidentally during procedures, some can lead to clinical issues and biliary complications, making knowledge of these variants crucial to prevent surgical mishaps. Here, we present an unusual and clinically significant case.

Adult intussusception: still a challenging diagnosis for the surgeon.

Introduction And Aim: Intussusception is rare in adults and can occur in the small bowel and colon. Its atypical presentation makes the diagnosis difficult. The aim of the present study was to evaluate the causes, clinical characteristics, and treatment outcomes of adult intussusception and to determine whether there was an association between etiology and clinical presentation.
