Ibero-American Consensus for the Management of Peritoneal Sarcomatosis: Updated Review and Clinical Recommendations.

Peritoneal sarcomatosis is a rare malignant disease with a poor prognosis, secondary to peritoneal dissemination of abdominopelvic soft tissue sarcomas. Its rarity, together with the characteristic histological heterogeneity and the historically poor response to systemic treatments, has prevented the establishment of widely accepted treatment criteria with curative intent. In this sense, radical cytoreductive surgery (CRS) with peritonectomy procedures and hyperthermic intraperitoneal chemotherapy (HIPEC), widely used in peritoneal carcinomatosis with excellent results, have not had the same evolutionary development in patients with peritoneal sarcomatosis.

Radical cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal sarcomatosis: Results from a reference center and considerations based on current evidence.

Introduction: Peritoneal sarcomatosis is a rare disease, with multiple histological origins and poor overall prognosis. The option of radical cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is controversial. The results of a surgical team experienced in these procedures are analyzed and discussed based on the available evidence.

Response to treatment and interval to surgery after preoperative short-course radiotherapy in rectal cancer.

Introduction: Preoperative short-course radiotherapy with immediate surgery improves local control in patients with rectal cancer. Tumor responses are smaller than those described with radiochemotherapy. Preliminary data associate this lower response to the short period until surgery.

New trends in the management of diverticulitis and colonic diverticular disease.

Colonic diverticular disease is a chronic disorder presenting with a variety of abdominal symptoms and recurrent episodes of acute diverticulitis. It is close linked to age so its prevalence has risen notably during the last decades in western countries, increasing costs related to medical attention. Recently, several works have provided evidence to a series of measures that could improve the outcomes as well as reduce expenses associated to this process.

Rectothecal fistula secondary to an anterior sacral meningocele.

A rectothecal fistula secondary to anterior sacral meningocele is an extremely rare disease. To the authors' knowledge, only 2 cases have been reported in the English-language literature. It can cause symptoms by compressing adjacent structures, causing urinary difficulties and constipation.
