Standardization of the definition of the types of oncological colectomy. Delphi method for consensus of experts of the Spanish Association of Surgeons.

There is no international consensus on the definition of the type of oncological resection that corresponds to each of the colectomies existing in the current literature. The objective is to define for each colectomy described in the literature: embryological dissection plane, vascular pedicles in which to perform central ligation, the extent of the colectomy, and the need for resection of the greater momentum. A consensus of experts is carried out through the Delphi methodology through two rounds from the Coloproctology Section of the Spanish Association of Surgeons.

Surgical treatment of acute diverticulitis. A retrospective multicentre study.

Introduction: To analyze short and medium-term results of different surgical techniques in the treatment of complicated acute diverticulitis (CAD).

Methods: Multicentre retrospective study including patients operated on as surgical emergency or deferred-urgency with the diagnosis of CAD.

Results: A series of 385 patients: 218 men and 167 women, mean age 64.

Effect of hospital caseload on long-term outcome after standardization of rectal cancer surgery in the Spanish Rectal Cancer Project.

Unlabelled: INTRODUCCIóN: The purpose of this prospective multicentre multilevel study was to investigate the influence of hospital caseload on long-term outcomes following standardization of rectal cancer surgery in the Rectal Cancer Project of the Spanish Society of Surgeons.

Methods: Data relating to 2910 consecutive patients with rectal cancer treated for cure between March 2006 and March 2010 were recorded in a prospective database. Hospitals were classified according to number of patients treated per year as low-volume, intermediate-volume, or high volume hospitals (12-23, 24-35, or ≥36 procedures per year).

[Hospital variation in anastomotic leakage after rectal cancer surgery in the Spanish Association of Surgeons project: The contribution of hospital volume].

Objective: This multicentre observational study aimed to determine the anastomotic leak rate in the hospitals included in the Rectal Cancer Project of the Spanish Society of Surgeons and examine whether hospital volume may contribute to any variation between hospitals.

Methods: Hospital variation was quantified using a multilevel approach on prospective data derived from the multicentre database of all adenocarcinomas of the rectum operated by an anterior resection at 84 surgical departments from 2006 to 2013. The following variables were included in the analysis; demographics, American Society of Anaesthesiologists classification, use of defunctioning stoma, tumour location and stage, administration of neoadjuvant treatment, and annual volume of elective surgical procedures.

Impact of a diverting stoma in an enhanced recovery programme for rectal cancer.

Purpose: The association of a loop ileostomy decreases the severity of complications after rectal surgery but can increase the postoperative stay. The aim of this study is to investigate if a diverting ileostomy influences the postoperative outcomes in a series of patients included in a multimodal rehabilitation program (MMRP).

Methods: We analyzed a series of 104 patients that underwent elective surgery with primary anastomosis for rectal adenocarcinoma using a MMRP: 66 men and 38 women, with a median age of 64 (IQR: 55-75) years.
