Recommended strategies to screen for Lynch syndrome in colorectal cancer are not applied in daily practice and most of Lynch cases remain undiagnosed.<br/><br/>Delphine Bonnet, Janick Selves, Christine Toulas, Marie Danjoux, Jean Pierre Duffas, Guillaume Portier, Sylvain Kirzin, Laurent Ghouti, Nicolas Carrère, Bertrand Suc, Laurent Alric, Karl Barange, Louis Buscail, Thierry Chaubard, Kamran Imani, Rosine Guimbaud (2012) <i>Dig Liver Dis</i> <i></i> <i></i> 44: 6 515-522<br/>

Aim:  The study aimed to assess, for the first time, the effectiveness of Interferential Therapy (IFT) in the treatment of slow-transit constipation in adults and its impact on the quality of life. Method:  All consecutive patients with slow-transit constipation diagnosed by symptomology and a colonic transit time (CTT) of >100 hours (h) measured with radiopaque markers were included in this p...<br/><br/>Michel Queralto, Véronique Vitton, Michel Bouvier, Anne Abysique, Guillaume Portier (2012) <i>Colorectal Dis</i> <i></i> <i></i> : <br/>

Optimal treatment of anal incontinence in a patients with a normal anal sphincter is controversial, as is the role of intra-anal rectal intussusception in anal incontinence. We evaluated the results of abdominal ventral rectopexy on anal continence in such patients.<br/><br/>G Portier, S Kirzin, P Cabarrot, M Queralto, F Lazorthes (2011) <i>Colorectal Dis</i> <i></i> <i></i> 13: 8 914-917<br/>

In human pathology, the "creeping fat" (CF) of the mesentery is unique to Crohn's disease (CD). CF is usually referred to as an ectopic extension of mesenteric adipose tissue (MAT). However, since no animal model developing CF has ever been established, very little is known about this type of fat-depot expansion and its role in the development of the disease.<br/><br/>Isabelle Olivier, Vassilia Théodorou, Philippe Valet, Isabelle Castan-Laurell, Hervé Guillou, Justine Bertrand-Michel, Christel Cartier, Valérie Bezirard, Robert Ducroc, Jean-Pierre Segain, Guillaume Portier, Sylvain Kirzin, Jacques Moreau, Jean-Pierre Duffas, Laurent Ferrier, Hélène Eutamène (2011) <i>Inflamm Bowel Dis</i> <i></i> <i></i> 17: 3 747-757<br/>

BACKGROUND: The aim of this randomized controlled trial was to assess the possible benefit of using a new haemostatic agent (Hémoionic) in the pelvic cavity in sphincter-saving surgery for rectal cancer. METHODS: Eighty-five patients undergoing elective sphincter-saving rectal resection for cancer were randomized into Hémoionic (41 patients) and control (44) groups. In both groups, a pelvic suct...<br/><br/>L Maggiori, E Rullier, C Meyer, G Portier, J L Faucheron, Y Panis (2010) <i>Br J Surg</i> <i></i> <i></i> 97: 4 479-484<br/>

PURPOSE: Abdominoperineal resection has a high rate of postoperative morbidity of the perineal wound. This study aimed to determine the effects of perineal colostomy on perineal morbidity after abdominoperineal resection. METHODS: All patients who underwent an abdominoperineal resection for rectal adenocarcinoma between 1993 and 2007 were studied. Two groups were identified and compared who had un...<br/><br/>S Kirzin, F Lazorthes, H Nouaille de Gorce, M Rives, R Guimbaud, G Portier (2010) <i>Dis Colon Rectum</i> <i></i> <i></i> 53: 9 1265-1271<br/>

In France, seton drainage followed by fistulotomy is currently the standard treatment for high cryptoglandular fistula-in-ano. Biological or synthetic glues, such as Glubran(®) 2, have been recently proposed for sealing the fistula tract. The purpose of this study is to determine the healing rate with glubran 2 and to assess the functional outcome after cure of fistula-in-ano.<br/><br/>M Queralto, G Portier, G Bonnaud, J-P Chotard, P Cabarrot, F Lazorthes (2010) <i>Gastroenterol Clin Biol</i> <i></i> <i></i> 34: 8-9 477-482<br/>

AIMS: The aim of the present study was to assess the clinical fate of, and to gain new insights into, branch duct and mixed (predominantly main duct type) forms of intraductal papillary mucinous neoplasia of the pancreas (IPMN). METHODS: During a 17-year period, 99 successive IPMN patients (52 men, 47 women; mean age, 64 years) were included and divided into two groups for further comparison: one ...<br/><br/>Barbara Bournet, Sylvain Kirzin, Nicolas Carrère, Guillaume Portier, Philippe Otal, Janick Selves, Carole Musso, Bertrand Suc, Jacques Moreau, Gilles Fourtanier, Bernard Pradère, Franck Lazorthes, Jean Escourrou, Louis Buscail (2009) <i>J Gastroenterol Hepatol</i> <i></i> <i></i> 24: 7 1211-1217<br/>

OBJECTIVE: Since the first paper published by Matzel et al., in 1995, on the efficacy of sacral nerve stimulation (SNS) in patients with faecal incontinence, the indications, the contraindications, the stimulation technique and follow up of implanted patients have changed.

PURPOSE: To assess the rate of R(0) resection of liver metastases achieved after chemotherapy with FOLFIRINOX.

The prognosis of patients with colorectal cancer is largely determined by the tumor stage. In this respect, colorectal cancer with lymph node metastases has the worst prognosis. Accordingly, there is considerable clinical interest in understanding the genetic mechanisms underlying metastasis formation. The short arm of chromosome 8 is often lost in colorectal cancer and has been associated with th...<br/><br/>Najat Mourra, Guy Zeitoun, Guillaume Portier, Hélène Blanche, Emmanuel Tubacher, Laetitia Gressin, Jean-François Flejou, Emmanuel Tiret, Gilles Thomas, Sylviane Olschwang (2008) <i>Diagn Mol Pathol</i> <i></i> <i></i> 17: 2 90-93<br/>

PURPOSE: Adjuvant systemic chemotherapy administered after surgical resection of colorectal cancer metastases may reduce the risk of recurrence and improve survival, but its benefit has never been demonstrated.

BACKGROUND: The value of ultra-low coloanal anastomosis (CAA) for rectal cancer is dependent on the oncological and functional results. The aim of this comparative study was to evaluate the long-term oncological outcome of CAA with or without intersphincteric resection (ISR) for low-lying rectal tumours.

Local recurrence (LR) after curative surgery for rectal cancer occurs in 4 to 33% of cases especially if surgery is sub-optimal (without total excision of the mesorectum). In many cases, diagnosis of LR is made at a late stage because of the high rate of asymptomatic patients, 56% in the experience of the Mayo Clinic. MRI and PETscan are most effective for assessing local and general extension, wi...<br/><br/>Laurent Ghouti, Guillaume Portier, Sylvain Kirzin, Rosine Guimbaud, Franck Lazorthes (2007) <i>Gastroenterol Clin Biol</i> <i></i> <i></i> 31: 1 55-67<br/>

PURPOSE: Complete resection of liver metastases of colorectal origin is the only potentially curative treatment. In order to decrease recurrences, the use of adjuvant systemic chemotherapy after liver resection is controversial because no randomized study demonstrated its benefit.

PURPOSE: Abdominal rectopexy is the preferred surgical technique for the treatment of total rectal prolapse. In many reported series, its results are impaired by induced constipation. Lateral rectal ligaments preservation could prevent constipation but increase recurrence rates.

The determination ofmicrosatellite instability (MSI) is an important step in the identification of familial colorectal cancer such as hereditary nonpolyposis colon cancer. It could also be of interest in the therapeutic management of sporadic cancer. International criteria for the determination of MSI have been published, recommending the use of microdissection.

PURPOSE: Few therapeutic tools are available for treating idiopathic anal incontinence.

Proctectomy followed by straight coloanal anastomosis (CAA) often results in poor functional outcome known as the anterior resection syndrome. It is now based on evidence that a colonic J-pouch CAA improves outcome in the first 2 years. We assessed the very late functional outcome of CAA patients with or without a pouch. These results show that the functional benefit of the J-pouch anastomoses is ...<br/><br/>Guillaume Portier, Ivan Platonoff, Frank Lazorthes (2005) <i>Recent Results Cancer Res</i> <i></i> <i></i> 165: 191-195<br/>

PURPOSE: Abdominoperineal resection, with iliac colostomy, remains the gold standard treatment for very low-lying rectal cancer, but it alters patients' quality of life. Alternatives to iliac colostomy need to be experimented. Antegrade enemas via a cecal access (Malone operation) obtains a colonic emptying and improves continence for incontinent patients.
