[Surgical resection and survival of clear cell renal cancer metastases to the pancreas].

Introduction: Pancreas is considered one of the organs most frequently affected by recurrence after nephrectomy secondary to renal cell carcinoma reporting an incidence of 20%, 85% of these occur within the first 3 years.

Objective: The objective of the study is to evaluate overall survival and disease-free survival in patients with renal cancer and pancreatic metastases who underwent surgical treatment.

Methods: A retrospective cross-sectional study of patients with histological diagnosis of renal cancer associated with pancreatic metastasis was performed and included those treated by pancreatoduodenectomy or distal pancreatectomy during the period 1987-2020.

Timely Access to Essential Surgery, Surgical Workforce, and Surgical Volume: Global Surgery Indicators in Mexico.

Introduction: The Lancet Commission on Global Surgery seeks to improve surgical care outcomes and equity for the world population through 6 indicators outlined in its 2030 Global Surgery Report. Our study aimed to estimate the percentage of the Mexican population with access to surgical care within the 2-hour distance range (indicator 1), the surgical workforce density (indicator 2), and the number of surgical procedures performed per 100,000 inhabitants (indicator 3) during the year 2020. Knowing these indicators can help to design and implement policies to increase surgical care access coverage and equity in our country.

Changes in chronic idiopathic ulcerative colitis epidemiological pattern in Mexico in a tertiary care hospital.

Background: Chronic idiopathic ulcerative colitis (CIUC) is a disease with multifactorial chronic inflammation of the colonic mucosa. Its prevalence ranges from 37.5-250/100,000 in North America to 10-500/100,000 in Europe.

Histopathologic Parameters at Diagnosis as Early Predictors of Histologic Remission along the Course of Ulcerative Colitis.

Background: Currently, the treatment goal in ulcerative colitis (UC) is to achieve clinical and endoscopic remission; nevertheless, histologic remission is a potential new treatment goal since it is associated with favorable long-term clinical outcome lower rates of hospitalization, complications, and colectomies.

Aim: Evaluate clinical and histopathologic characteristics at diagnosis as potential predictors of histologic remission in patients with ulcerative colitis.

Methods: This is a retrospective cohort study from 2007 to 2014, including 260 patients.

Factors Associated with the Presence of Extraintestinal Manifestations in Patients with Ulcerative Colitis in a Latin American Country.

Background And Aim: Ulcerative colitis (UC) is a subtype of inflammatory bowel disease that can develop extraintestinal manifestations (EIMs) in a subgroup of patients. The aim of this work was to study the frequency and clinical factors associated with the development of EIMs.

Methods: We evaluated a total of 260 Mexican patients with confirmed UC who were followed retrospectively in order to identify the factors associated with the presence of EIMs.

Clinical characteristics and surgical treatment of schwannomas of the esophagus and stomach: A case series and systematic review.

Background: Gastrointestinal schwannomas are slow-growing benign mesenchymal neoplasms that originate from Schwann cells of the nerve sheath of Auerbach´s plexus or less frequently from Meissner´s plexus. The main differential diagnosis of gastric schwannomas are the gastrointestinal stromal tumors (GISTs), which are classified by their immunohistochemistry. The treatment of choice for gastric schwannomas is surgery where laparoscopy plays an important role.

Acute cholecystitis in neutropenic patients.

Backgrounds/aims: The frequency of acute cholecystitis reported in neutropenic patients is between 0.4-1.65%.

Hand Ischemia due to Steal Syndrome Associated with Multiple Arteriovenous Malformations in a Patient with Parkes-Weber Syndrome.

Parkes Weber Syndrome (PWS) is a congenital disorder characterized by the presence of arteriovenous malformations (AVMs) in upper or lower extremities. We herein present a 35 year-old male with PWS with complex AVMs in the right upper extremity; he had been previously treated with multiple sessions of vessel embolization, sclerotherapy and AVM resections. The patient presented to our clinic with two month history of progressive hand ischemia, digit necrosis and infection.
