RESUMEN
BACKGROUND: Laparoscopic surgery offers patients with rectal cancer short-term benefits and similar survival rates as open surgery. However, selecting patients who are suitable candidates for laparoscopic surgery is essential to prevent intra-operative conversion from laparoscopic to open surgery. Clinical and pathological variables were studied among patients who had converted laparoscopic surgeries within the COLOR II trial to improve patient selection for laparoscopic rectal cancer surgery. METHODS: Between January 20, 2004, and May 4, 2010, 1044 patients with rectal cancer enrolled in the COLOR II trial and were randomized to either laparoscopic or open surgery. Of 693 patients who had laparoscopic surgery, 114 (16 %) were converted to open surgery. Predictive factors were studied using multivariate analyses, and morbidity and mortality rates were determined. RESULTS: Factors correlating with conversion were as follows: age above 65 years (OR 1.9; 95 % CI 1.2-3.0: p = 0.003), BMI greater than 25 (OR 2.7; 95 % CI 1.7-4.3: p < 0.001), and tumor location more than 5 cm from the anal verge (OR 0.5; CI 0.3-0.9). Gender was not significantly related to conversion (p = 0.14). In the converted group, blood loss was greater (p < 0.001) and operating time was longer (p = 0.028) compared with the non-converted laparoscopies. Hospital stay did not differ (p = 0.06). Converted procedures were followed by more postoperative complications compared with laparoscopic or open surgery (p = 0.041 and p = 0.042, respectively). Mortality was similar in the laparoscopic and converted groups. CONCLUSIONS: Age above 65 years, BMI greater than 25, and tumor location between 5 and 15 cm from the anal verge were risk factors for conversion of laparoscopic to open surgery in patients with rectal cancer.

Unequivocal international guidelines regarding the diagnosis and management of patients with acute appendicitis are lacking. The aim of the consensus meeting 2015 of the EAES was to generate a European guideline based on best available evidence and expert opinions of a panel of EAES members. After a systematic review of the literature by an international group of surgical research fellows, an expert panel with extensive clinical experience in the management of appendicitis discussed statements and recommendations. Statements and recommendations with more than 70 % agreement by the experts were selected for a web survey and the consensus meeting of the EAES in Bucharest in June 2015. EAES members and attendees at the EAES meeting in Bucharest could vote on these statements and recommendations. In the case of more than 70 % agreement, the statement or recommendation was defined as supported by the scientific community. Results from both the web survey and the consensus meeting in Bucharest are presented as percentages. In total, 46 statements and recommendations were selected for the web survey and consensus meeting. More than 232 members and attendees voted on them. In 41 of 46 statements and recommendations, more than 70 % agreement was reached. All 46 statements and recommendations are presented in this paper. They comprise topics regarding the diagnostic work-up, treatment indications, procedural aspects and post-operative care. The consensus meeting produced 46 statements and recommendations on the diagnostic work-up and management of appendicitis. The majority of the EAES members supported these statements. These consensus proceedings provide additional guidance to surgeons and surgical residents providing care to patients with appendicitis.

BACKGROUND: Surgical-site infection (SSI) and anastomotic leakage (AL) are major complications following surgical resection of colorectal carcinoma (CRC). The beneficial effect of prophylactic oral antibiotics (OABs) on AL in particular is inconsistent. We investigated the impact of OABs on AL rates and on SSI. METHODS: A systematic review and meta-analysis of recent RCTs and cohort studies was performed including patients undergoing elective CRC surgery, receiving OABs with or without mechanical bowel preparation (MBP). Primary outcomes were rates of SSI and AL. Secondarily, rates of SSI and AL were compared in broad-spectrum OABs and selective OABs (selective decontamination of the digestive tract (SDD)) subgroups. RESULTS: Eight studies (seven RCTs and one cohort study) with a total of 2497 patients were included. Oral antibiotics combined with MBP was associated with a significant reduction in SSI (RR = 0.46, 95% confidence interval (CI) 0.31-0.69), I2 = 1.03%) and AL rates (RR = 0.58, 95% CI 0.37-0.91, I2 = 0.00%), compared to MBP alone. A subgroup analysis demonstrated that SDD resulted in a significant reduction in AL rates compared to broad-spectrum OABs (RR = 0.52, 95% CI 0.30 to 0.91), I2 = 0.00%). CONCLUSION: OABs in addition to MBP reduces SSI and AL rates in patients undergoing elective CRC surgery and, more specifically, SDD appears to be more effective compared to broad-spectrum OABs in reducing AL.
RESUMEN
INTRODUCTION: Infectious complications and especially anastomotic leakage (AL) severely impede the recuperation of patients following colorectal cancer (CRC) surgery. When the normal gut barrier fails, as in AL, pathogenic microorganisms can enter the circulation and may cause severe sepsis which is associated with substantial mortality. Moreover, AL has a negative impact on the CRC prognosis. Selective decontamination of the digestive tract (SDD) employs oral nonabsorbable antibiotics to eradicate pathogenic microorganisms before elective tumour resection. METHODS: In this multicentre randomised clinical trial, perioperative SDD in addition to standard antibiotic prophylaxis is compared with standard antibiotic prophylaxis alone in patients with CRC who undergo elective surgical resection with a curative intent. The SDD regimen consists of colistin, tobramycin and amphotericin B. The primary objectives of this randomised clinical trial are to evaluate if perioperative SDD reduces the incidence of clinical AL and its septic consequences as well as other infectious complications. A main secondary objective is improvement of the cancer-free survival. A total of 762 patients will be included in total for sufficient power. CONCLUSION: It is hypothesised that SDD will reduce clinical AL thereby reducing the morbidity and the mortality in CRC patients. FUNDING: The trial is investigator-initiated, investigator-driven and supported by the Dutch Digestive Foundation (WO 11-06) and the private Posthumus Meyes Fund. TRIAL REGISTRATION: The trial is registered at ClinicalTrials.gov: NCT01740947.

INTRODUCTION: Gastrointestinal surgery is associated with a high incidence of infectious complications. Selective decontamination of the digestive tract is an antimicrobial prophylaxis regimen that aims to eradicate gastrointestinal carriage of potentially pathogenic microorganisms and represents an adjunct to regular prophylaxis in surgery. MATERIAL AND METHODS: Relevant studies were identified using bibliographic searches of MEDLINE, EMBASE, and the Cochrane database (period from 1970 to November 1, 2012). Only studies investigating selective decontamination of the digestive tract in gastrointestinal surgery were included. RESULTS: Two randomized clinical trials and one retrospective case-control trial showed significant benefit in terms of infectious complications and anastomotic leakage in colorectal surgery. Two randomized controlled trials in esophageal surgery and two randomized clinical trials in gastric surgery reported lower levels of infectious complications. CONCLUSION: Selective decontamination of the digestive tract reduces infections following esophageal, gastric, and colorectal surgeries and also appears to have beneficial effects on anastomotic leakage in colorectal surgery. We believe these results provide the basis for a large multicenter prospective study to investigate the role of selective decontamination of the digestive tract in colorectal surgery.
