Predictive value of IL-6 and IL-10 serum levels in anastomotic leakage in elderly patients undergoing surgery for colorectal cancer
2009
Methods The study group is yet represented by 33 patients: 17 males and 16 females (median age 76, range 70–89). The location of cancer was respectively: 5 (15, 15%) in the rectum, 15 (45, 45%) in the left colon, 11 (33, 33%) in the right colon, 1 (3, 3%) in the transverse colon, 1 (3, 3%) synchronous in the caecum and the sigmoid colon. The associated diseases observed were: chronic obstructive pulmonary disease, hypertension, diabetes mellitus, ischemic heart disease arterial vasculopathy.
What are the risk factors of failure of enhanced recovery after right colectomy? Results of a prospective study on 140 consecutive cases
2020
Purpose Nausea and vomiting is the main cause of failure of enhanced recovery protocol (ERP) after right hemicolectomy. Methods From January 2013 to January 2018, all patients undergoing right hemicolectomy were prospectively included. Patients undergoing emergency surgery, additional complex procedure or temporary stoma, nasogastric tube (NGT) maintenance, or abdominal drainage were excluded. Failure of ERP was defined as nausea/vomiting precluding oral feeding after POD3 and/or the occurrence of postoperative ileus requiring NGT and/or length of stay (LOS) ≥ 8 days except for patients awaiting admission in rehabilitation unit. Risk factors of failure of ERP were identified using univariat…
Pan-Asian adapted ESMO Clinical Practice Guidelines for the diagnosis treatment and follow-up of patients with localised colon cancer
2021
The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of localised colon cancer was published in 2020. It was decided by both the ESMO and the Japanese Society of Medical Oncology (JSMO) to convene a special virtual guidelines meeting in March 2021 to adapt the ESMO 2020 guidelines to take into account the ethnic differences associated with the treatment of localised colon cancer in Asian patients. These guidelines represent the consensus opinions reached by experts in the treatment of patients with localised colon cancer representing the oncological societies of Japan (JSMO), China (CSCO), India (…
Pelvic Autonomic Nerve Preservation during Total Mesorectal Excision (TME) from Werner Kneist
2017
According to the German guideline for “Colorectal Cancer,” total mesorectal excision (TME) removes the cancer located at the central and lower thirds of the rectum and the pelvic floor while preserving the superior hypogastric plexus (SHP), the hypogastric nerves, and the inferior hypogastric plexus (IHP) (recommendation level A, level of evidence 1b, strong consensus). Intraoperative nerve damage is to be avoided to preserve postoperative quality of life with the premise of radical surgery. It is particularly necessary to preserve autonomously controlled urogenital and anorectal functions. Among other things, this presumes a fundamental understanding of current events on surgical topograph…
Surgical and anatomical basis of autonomic nerve-preserving mesorectal excision for rectal cancer
2003
Adequate knowledge of the anatomy of the pelvis is a prerequisite to carry out a correct surgical technique in resection of rectal cancer. In this way, we can perform radical surgery, preserve the autonomic nerves and decrease local recurrence and urinary and sexual morbidity. The key to all this and the difference in results depends on a meticulous and detailed surgical technique.
Role of the gastroenterologist in the management of the obese patient.
2017
Obesity is a highly prevalent disease worldwide, and one in which gastroenterologists can play an important role. Some digestive diseases are more common in obese patients, and preoperative evaluation may be required in some cases. Additionally, bariatric surgery can lead to digestive complications in the short and long term that require intervention, and endoscopic treatment can be an important factor in weight loss. The aim of this review is to highlight the role of the gastroenterologist in the management of obese patients who are either scheduled for or have undergone surgical or endoscopic treatment for obesity.
Treatment guidelines of metastatic colorectal cancer in older patients from the French Society of Geriatric Oncology (SoFOG)
2020
International audience; Background: Several guidelines dedicated to metastatic colorectal cancer (mCRC) are available. Since 2013 no recent guidelines are specifically dedicated to older patients and based on a systematic review. Materials and methods: A multidisciplinary Task Force with digestive oncologists, geriatricians and methodologists from the SoFOG was formed in 2016 to update recommendations on medical treatment of mCRC based on a systematic review of publications from 2000 to 2018. Search strategy has followed a standardized protocol from the formulation of clinical questions and definition of a search algorithm to the selection of complete articles for recommendations. Results: …
Nonsurgical treatments for primary liver carcinoma in elderly patients: a 12-year retrospective study
2013
Introduction: Cancer is a leading cause of death. 70 percent of cases develop over the age of 65. Although a few patients with metastatic cancer are potentially resectable for cure (particularly those with isolated metastases), treatment for most patients is palliative and generally consists of systemic chemotherapy asoociated to target therapy. Objectives: To evaluate efficacy, safety and outcome of the addition of bevacizumab to chemotherapy in advanced cancer in elderly patients, a prospective study was carried on the last four years at Gonesse Hospital Group. Methods: Patients older than 65year with advanced metastatic (Stage IV) cancer (fourteen colorectal carcinoma, five breast carcin…
Color discrimination under mesopic conditions in cats and humans
1995
The ability to discriminate colors under various levels of mesopic illumination was studied in three cats using colored papers as stimuli and with a computer controlled training schedule. Discrimination based on brightness differences was prevented using a new method in which illuminant color was varied. The luminance threshold for color discrimination in cats was found to be 0.5 cd/m2, close to the cone threshold reported by others from ganglion cell recordings. The same experiment was carried out with human subjects and revealed a luminance threshold of 0.00042 cd/m2 for color discrimination.
Semi-automatic detection of skin malformations by analysis of spectral images
2013
The multi-spectral imaging technique to reveal skin malformations has been described in this work. Four spectral images taken at polarized monochromatic LED illumination (450nm, 545nm, 660nm and 940 nm) and polarized white LED light imaged by CMOS sensor via cross-oriented polarizing filter were analyzed to calculate chromophore maps. The algorithm based on skin color analysis and user-defined threshold selection allows highlighting of skin areas with predefined chromophore concentration semi-automatically. Preliminary results of clinical tests are presented.
