Timing of resection of synchronous colorectal liver metastasis: A systematic review and meta-analysis.

Introduction: The resection of the primary colorectal tumor and liver metastases is the only potentially curative strategy. In such cases, there is no consensus on whether the resection of the primary tumor and metastases should be performed simultaneously or whether a staged approach should be performed (resection of the primary tumor and after, hepatectomy, or the "liver first" approach). The aim of this study is to evaluate the results of hepatectomy associated with colectomy in colorectal neoplasms, comparing simultaneous and staged resection.

Decision making process in simultaneous laparoscopic resection of colorectal cancer and liver metastases. Review of literature.

Purpose: The benefits of laparoscopic approaches to treat colorectal cancer (CRC) and colorectal liver metastases (CRLM) separately are well established. However, there is no consensus about the optimal timing to approach the primary tumor and CRLM, whether simultaneously or staged. The objective of this review with practical reports is to discuss technical aspects required for patient selection to perform simultaneous laparoscopic approaches for CRC and CRLM.

Incidence of colorectal cancer in young patients.

Sporadic colorectal cancer (CRC) is traditionally diagnosed after de sixth decade of life, although a small percentage of cases are diagnosed in patients under 40 years of age, and incidence is increasing. There exists a great volume of controversy regarding clinical outcome of young patients diagnosed with colorectal cancer (CRC) when compared to elder counterparts. Our aims were to evaluate the rate of CRC in young patients, to review the pertaining literature and to discuss outcomes and clinical prognosis.

Short-term outcomes after laparoscopic colorectal surgery in patients with previous abdominal surgery: A systematic review.

Aim: To perform a systematic review focusing on short-term outcomes after colorectal surgery in patients with previous abdominal open surgery (PAOS).

Methods: A broad literature search was performed with the terms "colorectal", "colectomy", "PAOS", "previous surgery" and "PAOS". Studies were included if their topic was laparoscopic colorectal surgery in patients with PAOS, whether descriptive or comparative.

Doppler-guided hemorrhoidal dearterialization/transanal hemorrhoidal dearterialization: Technical evolution and outcomes after 20 years.

In the setting of Hemorrhoidal Disease treatment, the option of conventional hemorrhoidectomy is highly effective, but it is still associated with postoperative pain and discomfort. For this reason, technical alternatives have been developed in order to reduce complications and to provide better postoperative recovery. To accomplish this aim, non-excisional techniques such as stapled hemorrhoidectomy and Doppler-guided hemorrhoidal ligation have been introduced into clinical practice with high expectations.

Consolidation chemotherapy during neoadjuvant chemoradiation (CRT) for distal rectal cancer leads to sustained decrease in tumor metabolism when compared to standard CRT regimen.

Background: Neoadjuvant CRT may lead to significant tumor regression in patients with rectal cancer. Different CRT regimens with consolidation chemotherapy may lead to increased rates of complete tumor regression. The purpose of this study was to understand tumor metabolic activity following two different neoadjuvant CRT regimens using sequential PET/CT imaging in two different intervals following RT.

Colorectal cancer risk in hamartomatous polyposis syndromes.

Colorectal cancer (CRC) is a major cause of morbidity and mortality around the world, and approximately 5% of them develop in a context of inherited mutations leading to some form of familial colon cancer syndromes. Recognition and characterization of these patients have contributed to elucidate the genetic basis of CRC. Polyposis Syndromes may be categorized by the predominant histological structure found within the polyps.

Transanal local excision for distal rectal cancer and incomplete response to neoadjuvant chemoradiation - does baseline staging matter?

Background: Local excision may offer the possibility of organ preservation for the management of select patients after neoadjuvant chemoradiation. The oncological outcomes of this strategy have been largely associated with the risk of nodal metastases. Therefore, in addition to final ypT status, baseline staging has been suggested to potentially influence the outcomes of this treatment modality.

Surgery for small-bowel neuroendocrine tumors: is there any benefit of the laparoscopic approach?

Background: Surgery of small-bowel neuroendocrine (SBNE) tumors is demanding because of the need for associated extensive node dissection and assessment of possible synchronous lesions. For this reason, possible benefit of laparoscopy in SBNE tumors has not been reported to date.

Methods: From 1996, all patients operated on in Beaujon Hospital for SBNE tumors were retrospectively extracted from a prospectively maintained database of intestinal resections.
