Introduction: We evaluate the impact of COVID-epidemic in colorectal cancer (CRC) diagnosis during Spain's state of emergency.
Methods: We compared newly diagnosed patients with patients diagnosed in the same period of 2019.
Results: A new diagnosis of CRC decreased 48% with a higher rate of patients diagnosed in the emergency setting (12.
Background And Objetives: Due to the potential risks associated with stent placement, European Society Gastrointestinal Endoscopy does not recommend prophylactic insertion of stents in patients without symptoms. The aim was to compare complication rates, need of surgery, colostomy formation, and survival between stent placement prior to start of chemotherapy (SEMS group) and upfront ChT (ChT group) in patients with endoscopically non-transverable metastatic left-sided colorectal cancer.
Methods: Gender, age, CEA, tumor location, sites of metastatic disease, peritoneal involvement, liver involvement, and angiogenesis inhibitors administration, were recorded.
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).
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.
Objective: This multicentre observational study examines variation between hospitals in postoperative mortality after elective surgery in the Rectal Cancer Project of the Spanish Society of Surgeons and explores whether hospital volume and patient characteristics 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 rectal adenocarcinomas operated by an anterior resection or an abdominoperineal excision at 84 surgical departments from 2006 to 2013. The following variables were included in the analysis; demographics, American Society of Anaesthesiologists classification, tumour location and stage, administration of neoadjuvant treatment, and annual volume of surgical procedures.
Background: A surgical teaching and auditing program has been implemented to improve the results of treatment for patients with rectal cancer.
Objective: The aim of this study was to assess the treatment and outcome in patients resected for rectal cancer, focusing on differences relating to the type of resection.
Design: This was an observational study.
Purpose: The aim of this study was to compare one-stage colectomy of the descending colon without mechanical preparation in emergency and elective surgery.
Methods: From January 2004 to September 2009, 327 consecutive patients underwent surgery in a coloproctology unit for several conditions of the descending colon, 122 on an emergency basis and 205 as elective surgery. In the emergency surgery group, patients with septic shock, multiorgan failure, immunodeficiency or corticoid treatment, ASA IV stage, generalized fecal peritonitis (Hinchey IV stage), nonviable cecum or unresectable tumors were excluded (n = 54).
Objective: To evaluate the presence of psychiatric alterations in patients with fecal incontinence.
Patients And Method: Eighty consecutive patients (67 women) with fecal incontinence were evaluated. All the patients completed the the specific GHQ-28 questionnaire to evaluate psychiatric symptoms.
Introduction: The application of the laparoscopic approach to the treatment of rectal cancer is controversial. The aim of the present study was to evaluate whether the introduction of this technique in a coloproctology unit modified the quality of rectal cancer surgery.
Material And Method: We performed a prospective, nonrandomized study of all patients with rectal cancer who underwent surgery with curative intent in 2003 and 2004.
Surgery is the most effective treatment in patients with symptomatic grade III-IV hemorrhoids who have not responded to outpatient treatment, when there is associated abnormalities (anal fissure, anal fistula, skin tags) and in thrombosed hemorrhoids. Hemorrhoidectomy is currently the "gold standard" treatment. Randomized controlled trials comparing open with closed hemorrhoidectomy show no significant differences in pain scores.

Materials And Methods: Forty-seven patients undergoing Nissen 360 degrees fundoplication for gastroesophageal reflux were studied with pH recording and esophageal manometry before and 1 year after fundoplication. Amplitude of contraction of the distal third of the esophagus (ACDTE) and the presence of primary propulsive waves were studied.
