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.

The Educational Quality of Laparoscopic Right Hemicolectomy Videos on YouTube.

Surgical technique videos are an important part of surgical fellows' education. YouTube has been identified as the preferred source of educational videos among trainees The aim of this article is to objectively evaluate the quality of the 50 most viewed videos on YouTube concerning right laparoscopic hemicolectomy using LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS). We hypothesized that the number of likes or views will not necessarily reciprocate with the educational content.

Sociodemographic factors related with emergency colorectal cancer surgery at a referral center in Mexico.

Background: Diagnosis of colorectal cancer (CRC) after emergency presentation is associated with a worse prognosis.

Aim: The aim of the study was to determine the sociodemographic factors related with emergency CRC surgery at our institution.

Methods: From January 2009 to December 2017, patients that underwent CRC surgery at our institution were included in the study.

Thrombocytosis and Hyponatremia as Predictors of Complicated Acute Appendicitis: Predictors of Appendicitis.

Background: Multiple serologic markers have been studied to predict complicated acute appendicitis (CAA) (C-reactive protein and procalcitonin); these increase health care costs and are not always available in medical centers in Mexico. There is a need for low-cost serologic markers to predict CAA and guide the preoperative management of patients. Our objective was to analyze the predictive value of hyponatremia and thrombocytosis for complicated acute appendicitis.

Conversion from laparoscopic to open cholecystectomy: Risk factor analysis based on clinical, laboratory, and ultrasound parameters.

Introduction And Aims: The standard of care for gallbladder disease is laparoscopic cholecystectomy. Difficult dissection of the hepatocytic triangle and bleeding can result in conversion to open cholecystectomy, which is associated with increased morbidity. Identifying risk factors for conversion in the context of acute cholecystitis will allow patient care to be individualized and improve outcomes.

Laparoscopic Roux-en-Y gastric bypass in the treatment of obesity: evidence based update through randomized clinical trials and meta-analyses.

Bariatric surgery was introduced in 1953, but during the last 20 years its popularity has increased after the development of significant Romaevidenced based breakthroughs in the field. Currently, approximately 150 long-term randomized clinical trials and 40 meta-analyses support and give credibility to the surgical approaches for the treatment of obesity and its related metabolic disturbances. Bariatric surgery has demonstrated improved outcomes compared to medical treatment, conduct therapy, and endoscopic procedures.

Contrast-enhanced swallow study sensitivity for detecting esophagojejunostomy leakage.

Introduction And Aim: Sixty percent of the patients with gastric carcinomas are candidates for surgical resection through total gastrectomy and esophagojejunostomy, the latter of which is associated with leaks in up to 12.3% of cases. There is no standardized procedure for diagnosing anastomotic leaks.
