Abstract
Background Local excision (LE) after chemoradiotherapy is a new option in low rectal cancer, but morbidity has never been compared prospectively with total mesorectal excision (TME). Early and late morbidity were compared in patients treated either by LE or TME after neoadjuvant chemoradiotherapy for rectal cancer. Method This was a post-hoc analysis from a randomized trial. Patients with clinical T2/T3 low rectal cancer with good response to the chemoradiotherapy and having either LE, LE with eventual completion TME, or TME were considered. Early (1 month) and late (2 years) morbidities were compared between the three groups. Results There were no deaths following surgery in any of the three groups. Early surgical morbidity (20 per cent LE versus 36 per cent TME versus 43 per cent completion TME, P = 0.025) and late surgical morbidity (4 per cent versus 33 per cent versus 57 per cent, P < 0.001) were significantly lower in the LE group than in the TME or the completion TME group. of LE, was associated with the lowest rate of early (10 versus 18 versus 21 per cent, P = 0.217) and late medical morbidities (0 versus 7 versus 7 per cent, P = 0.154), although this did not represent a significant difference between the groups. The severity of overall morbidity was significantly lower at 2 years after LE compared with TME or completion TME (4 versus 28 versus 43 per cent grade 3–5, P < 0.001). Conclusion The rate of surgical complications after neoadjuvant chemoradiotherapy in the LE group was half that of TME group at 1 month and 10 times lower at 2 years. LE is a safe approach for organ preservation and should be considered as an alternative to watch-and-wait in complete clinical responders and to TME in subcomplete responders.

Abstract
AIMS OF THE STUDY The presence of colostomy has a major impact on quality of life that could potentially be improved by performing colonic irrigation (CI), yet few studies have assessed the impact of this technique on quality of life. The aim of this study was to assess the quality of life between two groups of patients having a colostomy; those practicing CI vs those not practicing CI. PATIENTS AND METHODS The French Federation of Ostomy (FFO) members were evaluated by a self-questionnaire assessing their experience of CI. Quality of life as assessed by the Stoma-QOL questionnaire was compared between patients practicing CI or not. RESULTS In total 752 patients were eligible for the study. The median age was 75 years, and 47.26% were men. The median duration between stoma surgery and questionnaire completion was 12.3 years. Forty-one percent of the patients practiced CI. The median quality of life score was significantly higher for the patients practicing the CI: (69.26 vs 58.33, P<0.001). In multivariable analysis, the risk factors for not performing CI were age, obesity, the presence of colostomy for less than six years, and a non-oncologic indication for operation. CONCLUSIONS CI appeared to improve the quality of life of patients with colostomy. This care is a therapeutic education issue and should be proposed to all patients. Supervision by the enterostomal therapy nurse is recommended especially for patients with a high risk of failure.

Abstract
BACKGROUND Intraoperative management based on thoracoscopy, prone position and two-lung ventilation could decrease the rate of postoperative pulmonary complications after esophagectomy. The aim of this study was to compare this multifaceted approach (MIE-PP) and conventional thoracotomy for Ivor Lewis procedure after a systematic laparoscopic dissection. METHODS Data from 137 consecutive patients undergoing Ivor Lewis procedures between 2010 and 2017 at two tertiary centers was analyzed retrospectively. The outcomes of patients who underwent MIE-PP (n = 58; surgeons group 1) were compared with those of patients undergoing conventional approach (n = 79; surgeons group 2). Our primary outcome was major postoperative pulmonary complications. Our main secondary outcomes were anastomotic leak, quality of resection and mortality. RESULTS Female patients were more prevalent in the MIE-PP group (p = 0.002). Other patient characteristics, cTNM staging and neoadjuvant treatment rate were not different between groups. Major postoperative pulmonary complications were significantly lower in the MIE-PP group compared to Conventional group (24 vs. 44%; p = 0.014). Anastomotic leak occurred in 31 versus 18% in MIE-PP group and Conventional groups, respectively (p = 0.103). Complete resection rate (98 vs. 95%; p = 0.303) and mean number of harvested lymph nodes (16 (4-40) vs. 18 (3-37); p = 0.072) were similar between the two groups. Postoperative mortality rates were 0 versus 2% at day 30 (p = 0.508) and 0 versus 7.6% at day 90 (p = 0.038). CONCLUSION Short-term outcomes of minimally invasive Ivor Lewis using thoracoscopy, prone position and two-lung ventilation are at least equivalent to the hybrid approach. Anastomotic leak after MIE-PP remains a major concern.

European Hernia Society guidelines on prevention and treatment of parastomal hernias. Hernia 2017; 22:183-198.

Abstract
BACKGROUND International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project. METHODS The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AGREE II standards and the GRADE methodology. The databases of MEDLINE, CINAHL, CENTRAL and the gray literature through OpenGrey were searched. Quality assessment was performed using Scottish Intercollegiate Guidelines Network checklists. The guidelines were presented at the 38th European Hernia Society Congress and each key question was evaluated in a consensus voting of congress participants. RESULTS End colostomy is associated with a higher incidence of parastomal hernia, compared to other types of stomas. Clinical examination is necessary for the diagnosis of parastomal hernia, whereas computed tomography scan or ultrasonography may be performed in cases of diagnostic uncertainty. Currently available classifications are not validated; however, we suggest the use of the European Hernia Society classification for uniform research reporting. There is insufficient evidence on the policy of watchful waiting, the route and location of stoma construction, and the size of the aperture. The use of a prophylactic synthetic non-absorbable mesh upon construction of an end colostomy is strongly recommended. No such recommendation can be made for other types of stomas at present. It is strongly recommended to avoid performing a suture repair for elective parastomal hernia. So far, there is no sufficient comparative evidence on specific techniques, open or laparoscopic surgery and specific mesh types. However, a mesh without a hole is suggested in preference to a keyhole mesh when laparoscopic repair is performed. CONCLUSION An evidence-based approach to the diagnosis and management of parastomal hernias reveals the lack of evidence on several topics, which need to be addressed by multicenter trials. Parastomal hernia prevention using a prophylactic mesh for end colostomies reduces parastomal herniation. Clinical outcomes should be audited and adverse events must be reported.

Abstract
Abstract
Background
The benefit of neoadjuvant chemotherapy (NCT) for early-stage oesophageal cancer is unknown. The aim of this study was to assess whether NCT improves the outcome of patients with stage I or II disease.
Methods
Data were collected from 30 European centres from 2000 to 2010. Patients who received NCT for stage I or II oesophageal cancer were compared with patients who underwent primary surgery with regard to postoperative morbidity, mortality, and overall and disease-free survival. Propensity score matching was used to adjust for differences in baseline characteristics.
Results
Of 1173 patients recruited (181 NCT, 992 primary surgery), 651 (55·5 per cent) had clinical stage I disease and 522 (44·5 per cent) had stage II disease. Comparisons of the NCT and primary surgery groups in the matched population (181 patients in each group) revealed in-hospital mortality rates of 4·4 and 5·5 per cent respectively (P = 0·660), R0 resection rates of 91·7 and 86·7 per cent (P = 0·338), 5-year overall survival rates of 47·7 and 38·6 per cent (hazard ratio (HR) 0·68, 95 per cent c.i. 0·49 to 0·93; P = 0·016), and 5-year disease-free survival rates of 44·9 and 36·1 per cent (HR 0·68, 0·50 to 0·93; P = 0·017).
Conclusion
NCT was associated with better overall and disease-free survival in patients with stage I or II oesophageal cancer, without increasing postoperative morbidity.

Abstract
PURPOSE OF THE STUDY The management of the severe blunt splenic injuries remains debated. The aim of this study is to evaluate the morbidity and mortality of splenic injury according to severity and management (surgery, embolization, non-operative management [NOM]). METHODS A prospective multicenter study was conducted including patients aged 16 years and older with diagnosed splenic injury. We evaluated severity according to the AAST classification, the presence of hemoperitoneum or a contrast blush on initial CT scan. The initial hemodynamic status, patients co-morbidities, the ISS (injury severity score), management and morbidity were also noted. RESULTS Between May 2010 and May 2012, 91 patients were included. Thirty-seven patients (41%) had mild splenic injury (AAST I or II and a small hemoperitoneum) while 54 patients (59%) had severe splenic injury (AAST III or greater). The management included 18 splenectomies (20%), 15 embolizations (16%). Among 67 patients undergoing NOM without initial embolization, five (7%) developed secondary bleeding, five required surgery and nine underwent secondary embolization. No patient died and morbidity was 44% (n=40), 13% for mild injuries vs. 65% for severe injuries (P<0.01). For severe injuries, total morbidity was 58% after NOM, 73% after embolization and 70% after surgery. Specific morbidity related to the management was 10% after NOM vs. 47% after embolization (P=0.02). Specific morbidity after surgery was 15%. CONCLUSION Embolization, because of its important specific morbidity, should not be performed as a prophylactic measure, but only in presence of clinical or laboratory signs of bleeding.

Abstract
AIM Curative surgery is the standard treatment for colorectal cancer. The ligation level of the inferior mesenteric artery (IMA) is still debated, as neither low tie (LT) nor high tie ligation (HT) has shown any benefit on the patients' overall survival. We examined whether LT is standardizable and easily reproducible from an anatomical point of view. METHOD One hundred CT angiographies of healthy patients were analysed for the anatomy of the IMA and its division branches: left colic artery (LCA), sigmoid arteries trunk and superior rectal artery. Data analysed comprised angles between the IMA and the aorta, diameters of the IMA and its branches, repartition of the branches and distances between the origin of the branches and the origin of the IMA. RESULTS IMA anatomy showed no variation. In contrast, its division branches showed important variability in terms of distance to the origin and repartition: in 19.9% of the patients, the IMA directly splits into three branches, and in 17.6% of the patients, the LCA originated at more than 5 cm from the origin of the IMA. These frequent variations led us to assume that the standardization of LT is very difficult in a context of neoplasm, where the quality of the lymphadenectomy is fundamental. CONCLUSION The division branches of the IMA are extremely subject to interindividual variations, making it difficult if not impossible to reproduce identically a surgical procedure based on their anatomy. HT appears to us as the only relevant procedure for colorectal cancer.

Abstract
AIM Genito-urinary complications are frequent after rectal surgery and are often due to nerve damage. The relationship between the pelvic nerves and surgical planes are unclear. The aim of the study was to determine the relationship between the inferior hypogastric plexus and the fascia of the lateral pelvic wall and between Denonvilliers' fascia and the efferent branches of the inferior hypogastric plexus. METHOD Computer-assisted anatomical dissection was used. Serial histological sections were made from six human foetuses and a male adult. Sections were stained with haematoxylin and eosin, Masson's trichrome and immunostainings. The sections were then digitalized and reconstructed in three dimensions. RESULTS The inferior hypogastric plexus was situated in a virtual space between the fascia propria of the rectum and the fascia on the upper surface of the levator ani. During the lateral dissection, the optimal surgical plane is the plane of the fascia propria of the rectum. We located Denonvilliers' fascia in three dimensions. It plays the role of a protective sheet for the neurovascular bundle. The optimal plane for nerve preservation is situated behind Denonvilliers' fascia. CONCLUSION This study has enabled a clear visualization of the optimal planes to perform total mesorectal excision while ensuring nerve preservation. Three-dimensional visualization clearly helps to bridge the gap between histological examination and the findings of surgery.

Abstract
GOAL OF STUDY Treatment of splenic injury is not standardized. We conducted an inventory of splenic injury treatment modalities of splenic injury in the Languedoc-Roussillon region of France. METHODS A questionnaire was sent by e-mail to 33 surgeons practicing in 10 hospitals in that region. Surgeons were asked: how many cases were treated per year (PMSI databank for the last three years), local resources (resuscitation bay or intensive care unit, availability of CT and interventional radiology), indications (surgery, embolization, nonoperative management [NOM]), prognostic criteria, NOM modalities (duration of bed rest, hospital stay, restriction of physical activity, thromboembolic prophylaxis, and imaging schedule). RESULTS Thirty-one surgeons replied. An average of 185 patients were treated per year. There was consensus concerning the indication for urgent splenectomy, NOM was practiced in the stable patient (even with diffuse hemoperitoneum) and splenic artery embolization was performed for active bleeding (blush on CT) (for the six centers who have interventional radiology at their disposal). Disparities existed between centers concerning the modalities of NOM excepting imaging monitoring, initial surveillance in resuscitation bay or intensive care and in the therapeutic indications when bleeding persisted. CONCLUSION Based on the consensus observed in this study and an analysis of the literature, a uniform treatment policy can be proposed.

Abstract
BACKGROUND Few studies have estimated Chlamydia trachomatis (CT) prevalence in the general population, most prevalence studies being based on people already attending healthcare settings. OBJECTIVES To estimate the prevalence of CT in France, assess the feasibility of home sampling without any face-to-face intervention and identify risk factors associated with CT infection using data from the Contexte de la Sexualité (CSF) survey on sexual behaviour; a national population-based survey, carried out by telephone in 2006. METHODS A random subsample of sexually experienced people aged 18-44 (N=4957) were invited to participate in a CT home-sampling study (NatChla study). Participants' samples were tested for CT by PCR. Percentages were weighted for unequal selection probabilities and post-stratified based on French population census data. Independent risk factors were identified by logistic regression. RESULTS CT prevalence in people aged 18-44 was estimated at 1.4% (95% CI 0.8% to 2.6%) for men, and 1.6% (95% CI 1.0% to 2.5%) for women. Increased rates were found in subjects aged 18-29: 2.5% (95% CI 1.2% to 5.0%) for men and 3.2% (95% CI 2.0% to 5.3%) for women. CT infection was associated, for both genders, with having their last sexual intercourse with a casual partner. Other risk factors were for men, having last intercourse with a new partner, living in the Paris area, and for women, multiple partners during the previous year, same sex partners and a low level of education. CONCLUSIONS CT prevalence in France is similar to that in other developed countries. Home sampling proved feasible and useful to reach members of the population with limited access to traditional care.

Pim-selective inhibitor DHPCC-9 reveals Pim kinases as potent stimulators of cancer cell migration and invasion. Mol Cancer 2010; 9:279. [PMID: 20958956 PMCID: PMC2978147 DOI: 10.1186/1476-4598-9-279] [Citation(s) in RCA: 56] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2010] [Accepted: 10/19/2010] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Pim family kinases are small constitutively active serine/threonine-specific kinases, elevated levels of which have been detected in human hematopoietic malignancies as well as in solid tumours. While we and others have previously shown that the oncogenic Pim kinases stimulate survival of hematopoietic cells, we now examined their putative role in regulating motility of adherent cancer cells. For this purpose, we inhibited Pim kinase activity using a small molecule compound, 1,10-dihydropyrrolo[2,3-a]carbazole-3-carbaldehyde (DHPCC-9), which we had recently identified as a potent and selective inhibitor for all Pim family members. RESULTS We now demonstrate that the Pim kinase inhibitor DHPCC-9 is very effective also in cell-based assays. DHPCC-9 impairs the anti-apoptotic effects of Pim-1 in cytokine-deprived myeloid cells and inhibits intracellular phosphorylation of Pim substrates such as Bad. Moreover, DHPCC-9 slows down migration and invasion of cancer cells derived from either prostate cancer or squamocellular carcinoma patients. Silencing of Pim expression reduces cell motility, while Pim overexpression enhances it, strongly suggesting that the observed effects of DHPCC-9 are dependent on Pim kinase activity. Interestingly, DHPCC-9 also abrogates NFATc-dependent migration of cancer cells, implying that NFATc factors mediate at least part of the pro-migratory effects of Pim kinases. CONCLUSIONS Altogether, our data indicate that DHPCC-9 is not only a powerful tool to investigate physiological effects of the oncogenic Pim family kinases, but also an attractive molecule for drug development to inhibit invasiveness of Pim-overexpressing cancer cells.

Abstract
Coloproctectomy with ileo-anal anastomosis (CP-IAA) has been in use for 30 years. This intervention is the standard technique when surgery is indicated for familial adenomatous polyposis (FAP) and for ulcerative colitis (UC). Although the surgery is safe with mortality of less than 1%, it is associated with a morbidity of 18-70%. We thought a literature review about long-term complications would be enlightening. Pouchitis is the most common complication; it occurs in 70% of patients over 20 years follow-up; small bowel obstruction affects 25% of patients and pelvic sepsis occurs in 20-30% within 10 years. CP-IAA can impact the patient's sexual life due to erectile and ejaculatory dysfunction, dyspareunia, and incontinence of stool during sexual intercourse. Nevertheless, patients with long-standing UC describe an overall improvement in their sexual function after surgery. The failure rate varies from 3.5 to 15%; major causes of failure are sepsis, unrecognized Crohn's disease, and poor functional results. Cases of dysplasia and cancer have been reported in the reservoir, but more particularly when there is retained colonic glandular mucosa. The transitional zone should be monitored whenever there are risk factors for colon neoplasia. The relatively high morbidity of CP-IAA should not overshadow the good functional results of this technique.

Abstract
OBJECTIVE To study anatomical risks after posterior sacrospinous ligament fixation using the CAPIO needle driver. SUBJECTS AND METHODS A simplified bilateral posterior sacrospinous ligament fixation was performed on seven fresh female cadavers using the CAPIO needle driver. Cadavers were installed in gynaecologic position then dissected by the abdominal route. The posterior sacrospinous ligament fixation was performed after a posterior vaginal wall incision on the midline and a simplified dissection of both pararectal fossae. The abdominal dissection was focused on the sacrospinous ligament area. We measured the distance between the neurovascular elements adjacent to the sacrospinous ligament from the suture site. RESULTS Thirteen sacrospinous ligaments were available for analysis. The mean length (+/-SD) of the ligament was 51+/-9.2 mm and the mean width at the level of fixation (+/-SD) was 23.5+/-5.7 mm. No rectal injury was observed. Fixations were in the deeper (ligament) and medium (muscle) part of the SSL in eight (61%) and five (39%) cases respectively. The ischial spine was 21.6 mm (range: 13-30). The mean distances between fixation and pudendal nerve and artery were 16.1 mm (range: 4-32) and 20 mm (range: 12-37) respectively. CONCLUSION Mini-invasive posterior sacrospinous ligament fixation using the CAPIO needle driver seemed to be reproducible with low anatomical risks. However, the fixation should be at least at 20 mm medially to the ischial spine in order to reduce neurological risks.

Abstract
AIM OF THE STUDY Lymph node involvement is one of the most significant prognostic factors of patients with rectal cancer. Despite major advances in our understanding of the propagation of the rectal cancer, the lymphatic drainage of the rectum remains unclear. This study was designed to assess the number of lymph nodes located around the superior rectal artery and to assess the frequency of Mondor's lymph nodes. PATIENTS AND METHODS Twenty-five anatomic subjects were studied. All resections were performed using total mesorectal excision. Lymph nodes were sought in the tissue surrounding the superior rectal artery up to 2 cm under the ending of the superior rectal artery by manual dissection and were submitted for histological examination. The correlation between the number of lymph nodes, and the volume and weight of the tissue surrounding the superior rectal artery was evaluated by non-parametric Spearman test. RESULTS The mean number of lymph nodes per specimen was 2.7 +/- 1.4. The size of the lymph nodes varied between 1 and 7 mm. The lymph nodes were mostly smaller than 3 mm (56%). The number of lymph nodes in the superior rectal mesentery was independent of its volume and its weight. Seven subjects had a Mondor's lymph node. The mean size of Mondor's lymph node was 3.4 +/- 2.1 cm. CONCLUSIONS The number of NL located around the superior rectal artery is small, varying between 1 and 5. The Mondor's lymph node is an inconstant rectal NL. Its only characteristic is its location in the bifurcation or trifurcation of the superior rectal artery.

Abstract
Members of the Pim kinase family have been identified as promising targets for the development of antitumor agents. After a screening of pyrrolo[2,3-a]- and [3,2-a]carbazole derivatives toward 66 protein kinases, we identified pyrrolo[2,3-a]carbazole as a new scaffold to design potent Pim kinase inhibitors. In particular, compound 9 was identified as a low nM selective Pim inhibitor. Additionally, several pyrrolo[2,3-a]carbazole derivatives showed selectivity for Pim-1 and Pim-3 over Pim-2. In vitro antiproliferative activities of 9 and 28, the most potent Pim inhibitors identified, were evaluated toward three human solid cancer cell lines (PA1, PC3, and DU145) and one human fibroblast primary culture, revealing IC50 values in the micromolar range. Finally, the crystal structure of Pim-1 complexed with lead compound 9 was determined. The structure revealed a non-ATP mimetic binding mode with no hydrogen bonds formed with the kinase hinge region and explained the selectivity of pyrrolo[2,3-a]carbazole derivatives for Pim kinases.
