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.

Pigmented basal cell carcinoma of the anus: a rare entity with diagnostic challenges.

Anal cancer is uncommon, comprising 2.2% of gastrointestinal cancers. Squamous cell carcinoma (SCC) is the most common; while perianal basal cell carcinoma (BCC) is rare, representing only 0.

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.

Prognostic and predictive value of neutrophil-to-lymphocyte ratio after curative rectal cancer resection: A systematic review and meta-analysis.

Background: Neutrophil-to-lymphocyte ratio (NLR) has been shown to be associated with poor prognosis in numerous solid malignancies. Here, we quantify the prognostic value of NLR in rectal cancer patients undergoing curative-intent surgery, and compare it with platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR).

Methods: A comprehensive search of several electronic databases was performed through January 2021, to identify studies evaluating the prognostic impact of pretreatment NLR in patients undergoing curative rectal cancer resection.

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.

Sarcopenia predicts worse postoperative outcomes and decreased survival rates in patients with colorectal cancer: a systematic review and meta-analysis.

Purpose: Previous studies have shown an association of sarcopenia with adverse short- and long-term outcomes in multiple gastrointestinal cancer types. We aimed to investigate the prognostic value of sarcopenia on the postoperative outcomes and survival rates of patients with colorectal cancer (CRC).

Methods: A systematic literature search was performed using the PubMed, Embase, Cochrane, Google Scholar, and Scopus databases.

Assessment of quality-of-care indicators for colorectal cancer surgery at a single centre in a developing country.

Background: The implementation of quality-of-care indicators aiming to improve colorectal cancer (CRC) outcomes has been previously described by Cancer Care Ontario. The aim of this study was to assess the quality-of-care indicators in CRC at a referral centre in a developing country and to determine whether improvement occurred over time.

Methods: We performed a retrospective study of our prospectively collected database of patients after CRC surgery from 2001 to 2016.

A systematic review and meta-analysis of diverting loop ileostomy versus total abdominal colectomy for the treatment of Clostridium difficile colitis.

Background: Clostridium difficile is an increasingly common source of in-patient morbidity and mortality. We aim to assess the effects of diverting loop ileostomy (DLI) versus total abdominal colectomy (TAC) for Clostridium difficile colitis (CDC), in terms of mortality and morbidity.

Methods: Systematic literature search was performed using PubMed, Embase, Cochrane, and Web of Science databases for randomized and non-randomized studies comparing DLI and TAC for fulminant CDC.

Sarcopenia in patients with colorectal cancer: A comprehensive review.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer globally and the second cancer in terms of mortality. The prevalence of sarcopenia in patients with CRC ranges between 12%-60%. Sarcopenia comes from the Greek "sarx" for flesh, and "penia" for loss.
