Correction to: Quantifying the extent of fistulotomy. How much sphincter can we safely divide? A three-dimensional endosonographic study.

In the Fig. 1 of the original published version of this article the numbers were switched as well as in the text of Results section, lines 5 and 6. The revised figure and the corrected text are now presented correctly in this article.

[Ambulatory laparoscopic cholecystectomy. A cohort study of 1,600 consecutive cases].

Objective: A descriptive analysis of day-case laparoscopic cholecystectomy (ALC) in a cohort of 1,600 consecutive patients performed in Instituto de Cirugía y Aparato Digestivo (ICAD), Clínica Quirón de Valencia in the period 1997-2010.

Patients And Methods: Prospective observational study of 1,601 consecutive patients undergoing elective laparoscopic cholecystectomy (LC) provided by the regional health service and private health companies.

Main Measures: Conversion rate, non-planned admissions, readmissions, surgery duration and demographics.

[Evaluation of the gastrointestinal quality of life index as a system to prioritize patients on the waiting list for laparoscopic cholecystectomy].

Introduction: We prospectively evaluated health-related quality of life (HRQoL) through the gastrointestinal quality of life index (GIQLI) as a system to prioritize patients on the waiting list for laparoscopic cholecystectomy (LC) and its correlation with a linear prioritization system developed in the General and Gastrointestinal Surgery Institute of Clínica Quirón in Valencia.

Material And Methods: There were 100 consecutive patients who underwent elective outpatient LC. The main outcome measures consisted of: 1) assessment of the impact of the disease, measured through the GIQLI; 2) evaluation of an objective system based on technical scientific criteria; 3) evaluation of the utility of LC in improving HRQoL through the GIQLI by analyzing expected and obtained utility through the change ratio, and 4) analysis of the correlation between the objective linear system, HRQoL and utility.

Quantifying the extent of fistulotomy. How much sphincter can we safely divide? A three-dimensional endosonographic study.

Purpose: To quantify the longitudinal division of the internal anal sphincter (IAS) and external anal sphincter (EAS) after fistulotomy using three-dimensional endoanal ultrasound (3D-EAUS) and correlate the results with postoperative faecal incontinence.

Methods: A prospective, consecutive study was performed from December 2008 to October 2010. All patients underwent 3D-EAUS before and 8 weeks after surgery.

[Pain, analgesic consumption and daily life activities recovery in patients undergoing ambulatory totally extra-peritoneal laparoscopic inguinal hernioplasty versus ambulatory Lichtenstein hernioplasty].

Introduction: Although the unique comparison standard of primary inguinal hernia repair is the Lichtenstein technique (LICH), totally extra-peritoneal (TEP) laparoscopic inguinal hernioplasty shows, although not systematically demonstrated, clear advantages as regards, perceived pain, analgesic use, and recovery of daily life activities.

Objective: To demonstrate the differences in perceived pain, analgesic use, and recovery of daily life activities between Lichtenstein hernioplasty and TEP laparoscopy.

Material And Methods: A prospective, non-randomised observational study was conducted on 169 consecutive patients subjected to LICH vs TEP.

[Evaluation of three-dimensional endoanal endosonography of perianal fistulas and correlation with surgical findings].

Objective: This study aims to assess the accuracy of three-dimensional endoanal ultrasound (3D-US), two-dimensional ultrasound (2D-US) and physical examination (PE) for the diagnosis of perianal fistulas and correlate the results with intraoperative findings.

Materials And Methods: A prospective, observational study with consecutive inclusion of patients was performed between December 2008 and August 2009. Twenty-nine patients diagnosed with a perianal fistula due to undergo surgery were included.

[Intraoperative factors predictive of failure of the ambulatory regimen after laparoscopic cholecystectomy].

Objectives: To determine which intraoperative factors during ambulatory laparoscopic cholecystectomy predict postoperative admission.

Material And Method: Between January 1999 and August 2003, we attempted 410 consecutive laparoscopic cholecystectomies. Intraoperative variables were analyzed using univariate and multivariate methods.

The learning curve in ambulatory laparoscopic cholecystectomy.

Whether laparoscopic cholecystectomy (LC) should be performed as an outpatient procedure is still under discussion. The aim of this study was to evaluate the influence of surgeon's experience in ambulatory management of LC. Three hundred eighty-one consecutive elective LCs were planned as outpatient procedures.
