RESUMEN
AIM OF THE STUDY: Right colonic Diverticulitis (RD) is rare in Europe; few studies have focused on it and its management is not standardised. The aim of this study was to analyse the clinical presentation (complicated, uncomplicated), acute phase management and long-term outcome of RD in western countries. PATIENTS AND METHODS: From 2003 to 2017, 93 consecutive patients who presented with RD were retrospectively included at 11 French Hospital Centres. RESULTS: The study population consisted of two groups: Uncomplicated Right Diverticulitis (URD) group (63.5%, (n=59)) and Complicated Right Diverticulitis (CRD) group (36.5%, [n=34]). 84.7% (n=50/59) of URD were treated conservatively. 41.2% (n=14/34) of patients with CRD had emergency surgery (mostly laparotomy) for Hinchey III peritonitis, clinical intolerance or hemodynamic instability. Altogether 5.2% (n=2/34) patients with CRD had surgery after a cooling off period (initially abscess). The overall rate of severe postoperative complications was low (8%). Recurrence rate was low and comparable in both groups: 6.8% (n=4/59) for URD and 8.8% (n=3/34) for CRD, all recurrences occurred in the same locations with an uncomplicated form, 42.9% (n=3/7) of them had elective laparoscopic surgery and the rest were conservatively treated. Median follow up was 33.2 months. CONCLUSION: Conservative treatment can be proposed safely and efficiently for URD and for selected patients with CRD. Surgery should be reserved for unstable patients or patients with severe forms of complicated diverticulitis in emergency.

Iron/sulfur clusters are key cofactors in proteins involved in a large number of conserved cellular processes, including gene expression, DNA replication and repair, ribosome biogenesis, tRNA modification, central metabolism and respiration. Fe/S proteins can perform a wide range of functions, from electron transfer to redox and non-redox catalysis. In all living organisms, Fe/S proteins are first synthesized in an apo-form. However, as the Fe/S prosthetic group is required for correct folding and/or protein stability, Fe/S clusters are inserted co-translationally or immediately after translation by specific assembly machineries. These systems have been extensively studied over the last decade, both in prokaryotes and eukaryotes. The present review covers the basic principles of the bacterial housekeeping Fe/S biogenesis ISC system, and related recent molecular advances. Some of the most exciting recent highlights relating to this system include structural and functional characterization of binary and ternary complexes involved in Fe/S cluster formation on the scaffold protein IscU. These advances enhance our understanding of the Fe/S cluster assembly mechanism by revealing essential interactions that could never be determined with isolated proteins and likely are closer to an in vivo situation. Much less is currently known about the molecular mechanism of the Fe/S transfer step, but a brief account of the protein-protein interactions involved is given. This article is part of a Special Issue entitled: Fe/S proteins: Analysis, structure, function, biogenesis and diseases.

Port-site metastasis is a rare but serious complication of laparoscopic surgery. The etiologies are poorly identified and multiple. We report the case of port-site metastasis after laparoscopic retroperitoneal lymphadenectomy for endometrial adenocarcinoma. In the literature, three cases of port-site metastasis after laparoscopic retroperitoneal lymphadenectomy are reported: two cases concerning cervical cancer and one case concerning a kidney cancer. To our knowledge, this is the only case about port site metastasis after laparoscopic retroperitoneal lymphadenectomy for endometrial adenocarcinoma.

OBJECTIVE: To evaluate feasibility of single laparoscopic access with LESS(®) system. PATIENTS AND METHODS: We conducted an open study from 1/7/2009 to 1/10/2010 in a single gynaecologic department. All procedures were performed by four operators. Procedures evaluated were total hysterectomy, adnexectomy and ovarian cystectomy. Feasibility, per- and postoperative data were reported. RESULTS: We performed completely 24/25 (96 %) total hysterectomies by single laparoscopic access. Traditional laparoscopy and finally laparotomy was necessary for one patient. Bladder injury repaired by vaginal approach was reported in one patient. We performed 29 adnexectomies in 19 patients (nine unilaterals et 10 bilaterals) and six ovarian cystectomies in four patients (four unilaterals et two bilaterals). All procedures were performed successfully by single laparoscopic access. Parietal haematoma were reported in two patients. DISCUSSION AND CONCLUSION: Laparoscopic gynaecologic surgery by single access seems feasible with LESS(®) system for these procedures. Further study including larger number of patients and operators were necessary to confirm risks and advantages of this technique.

The idea that pelvic cancers can be treated by laparoscopy is now commonly admitted among gynaecological surgeons. Literature shows a lower morbidity than laparotomy, with similar prognostic results. Metastatic invasion of para-aortic lymph nodes is a major prognostic factor in gynaecological malignancies. It modifies the therapeutic plan and requires retroperitoneal lymphadenectomy in many indications. Laparoscopy is an interesting technical procedure in this situation: it allows both staging and curative surgery. Two laparoscopic ways are eligible: transperitoneal lymphadenectomy and retroperitoneal lymphadenectomy.

RESUMEN
Over the last 20 years, the treatment of acute appendicitis has been transformed by the development of the laparoscopic approach. And yet the net value of this approach continues to be debated. Laparoscopic appendectomy is associated with a lower complication rate and a shorter period of disability in the general population. While operative costs are higher, the global cost of laparoscopic appendectomy is lower than for open appendectomy. There is a somewhat higher rate of abdominal abscess for the laparoscopic route. Laparoscopic appendectomy shows clear advantages in obese patients and in those with gangrenous or ruptured appendicitis. The laparoscopic approach is contra-indicated during pregnancy due to a higher incidence of miscarriage. Treatment of the appendiceal stump by ligature decreases the expense associated with the use of a surgical stapler. When Meckel's diverticulum is encountered during appendectomy, it should be removed in all pediatric patients; in adults, Meckel's diverticulectomy in adults should be performed only for clear-cut pathology. Surgeons continue to innovate and refine appendectomy techniques but many questions remain to be answered.

INTRODUCTION: For non-invasive intraductal papillary and mucinous neoplasm (IPMN) with limited extent, pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) seem excessive due to the risk of pancreatic insufficiency. Enucleation (EN) or medial pancreatectomy (MP) are not commonly performed for IPMN. The aim of this study was to evaluate the feasibility and results of EN and MP for non-invasive IPMN. PATIENTS AND METHODS: Of 249 patients with IPMN, we attempted a limited resection in 50 (20%) EN (n=31) or MP (n=20) with routine intra-operative frozen section pathology. One attempted EN was converted to MP. Indications for surgery were pain/pancreatitis (44%), suspicion of main duct involvement (28%), mural nodules in branch duct (14%), branch duct>30 mm (8%) or suspicion of mucinous cystadenoma (6%). Follow-up clinical assessment and MRI were performed on a yearly basis. RESULTS: Of the 31 attempted enucleations, 5 (13%) were immediately converted (4 PD, 1 MP) due to technical reasons (n=3) or due to findings on frozen section (n=2). At definitive pathological examination (accuracy of frozen sectioning=98%), branch ducts were involved by mild (n=21), moderate (n=7) or high grade dysplasia (n=2). One patient underwent a double EN. Of 20 attempted medial pancreatectomies, 8 (40%) required additional segmental resection due to significant IPMN lesions at pancreatic margins; 3 of the additional resection margins were tumor-free, and 5 were involved by IPMN (4 conversions to PD or DP, one contra-indication to PD). Overall, 49 pancreatic margins were analyzed by frozen sectioning with 98% accuracy. Resected specimens of 16 MP showed involvement by mild (n=7), moderate (n=7) or high grade dysplasia (n=2). There was no postoperative mortality. Median length of stay was 21 and 30 days respectively after EN and MP. Pancreatic fistula rate was 54% and 81% respectively after EN and MP. Three patients underwent early re-operation for hemorrhage. Overall median follow-up was 24 months (3-121). All patients are alive, 2 patients (5%) have presented with recurrent pain and 4 have developed tumor recurrence on imaging follow-up (4/33=12%). Two patients (5%) developed de novo diabetes (one after EN combined with DP) and a third patient developed worsening of pre-existing diabetes plus exocrine insufficiency. No patient had surgery for recurrence. CONCLUSIONS: EN and MP are feasible for non-invasive IPMN. Their significant early morbidity is counterbalanced by low rates of both long-term functional disorders and tumor recurrence.

OBJECTIVE: The purpose of the study was to report surgical techniques for pelvic organ prolapse and complications in women aged more than 70 years. PATIENTS AND METHODS: A Medline search was made for articles indexed between 2000 and 2006 and dealing with operative techniques for pelvic organ prolapse. Seven articles in English and French were included. RESULTS: Three hundred and ninety-four women were treated for pelvic organ prolapse. Transvaginal repairs were reported in 97% (384 women). Vaginal function was preserved in 57% (207 women) and vaginal obliteration techniques represented 40% (145 women) of all prolapse surgery. The death rate was 1% (four deaths). The blood transfusion rate was 12%. The mean complication rate was 3.8% with cardiovascular prevalence (seven pulmonary embolisms, two myocardial infarctions, two congestive heart failures, one prolonged angina, two transient arrhythmias, one cerebrovascular accident, one acute renal failure). The temporospatial disorientation rate was 4.6%. DISCUSSION AND CONCLUSION: Vaginal hysterectomy with colpo-perineorrhaphy and sacrospinous ligament fixation are alternative procedures instead of colpocleisis to treat pelvic organ prolapse in women aged more than 70 years. For all pelvic prolapse surgery, the overall perioperative morbidity and mortality rate in elderly women are acceptable. This surgery needs a good collaboration between anesthetist and surgeon team and vigilance during postoperative follow-up.

OBJECTIVE: The traditional access of perineum for the treatment of the pelvic organ prolapse by vaginal route is probably responsible for the risk of mesh exposure and a longer convalescence. So, endoscopic access to perinemeum needs to be evaluated. PATIENTS AND METHODS: Feasibility study on cadavers. Details of the procedure: opening of the pararectal space by digital dissection first after incision on the level of the posterior commissure. Introduction of an optical trocart to the level of the perineum incision; dissection of pararectal space with optics and CO(2); individualization of the various elements; installation of a transobturator trocart and a transgluteal trocart; dissection of the rectovaginal septum and visualization of the sacrospinous ligament and pudendal nerve. The measured variables were: operational incidents, possibility of creation of working space, dissection of the rectovaginal septum; finally, visualization of the sacrospinous ligament and pudendal pedicle. RESULTS: On the 4 studied cadavers, we could carry out a dissection of pelvirectal space in all the cases. On the 8 pararectal fosses, in all the cases we could carry out a cavity of dissection and to open the recto vaginal septum, visualization of the sacrosciatic ligament and pudendal pedicle was possible in 6 cases out of 8. There were one rectal injury, two vaginal injuries and one lesion of the pudendal pedicle. DISCUSSION AND CONCLUSION: This endoscopic access allows in the majority of cases to see the structures necessary to the realization of a vaginal sacrospinofixation or the installation of posterior mesh without a colpotomy and a traumatic exposure. The incidents are probably due to our inexperience and should disappear in time. The pelvi-perineoscopy is an endoscopic access of perineum which should be evaluated.

OBJECTIVE: The aim of this study was to assess the role of cervical length measurement in predicting successful treatment, by misoprostol administration, of early (first-trimester) pregnancy failure. METHOD: A prospective study was conducted of all patients who agreed to medical treatment of pregnancy failure. Cervical length and other sonographic variables were measured using pelvic ultrasound before medical treatment began. Measurements were compared between the group with successful medical treatment and the group in whom treatment failed. RESULTS: In 125 women included in the study, the success rate of misoprostol treatment was 64.8%. There were no significant differences between the groups with successful and failed treatment for cervical length (29.9 +/- 9.3 vs. 30.4 +/- 6.8 mm, P = 0.75), distance between gestational sac and 'virtual' cervical internal os (23.9 +/- 13 vs. 26.6 +/- 13 mm, P = 0.26), crown-rump length (8.7 +/- 9.7 vs. 6.7 +/- 8.6 mm, P = 0.25), or gestational sac diameter (31.3 +/- 14 vs. 30.1 +/- 15 mm, P = 0.73). CONCLUSION: Cervical length does not predict the success of misoprostol treatment of first-trimester pregnancy failure.

OBJECTIVE: The aim of this study was to compare the Joel-Cohen method for cesarean section to the traditional transrectal incision. METHOD: Fifty-two patients requiring a caesarean section were enrolled in this prospective study. Overall morbidity and post-operative pain was assessed. Four surgeons participated to this study, each included 13 patients. The main judgement criterion was post-operative pain on the first day. RESULTS: Post-operative pain on the first day was less important (50 vs 23% p=0.04) in Joel-Cohen's. This method was shorter compared to the transrectal incision (33.6+6.4 min vs 51.2+8 min p<0.0001). There was no difference in overall morbidity between the two groups. CONCLUSION: Joel-Cohen's method decrease post-operative pain and is a shorter procedure compared to the transrectal incision.

OBJECTIVE: To assess the impact of the surgical route on the management and outcome of early borderline ovarian tumors (BOT). PATIENTS AND METHODS: We have retrospectively analysed BOT operated on between January 1st 1985 and December 31st 2001. We included cases with clinical stages Ia to Ic. We compared the prevalence of deleterious acts according to the surgical access, as well as the quality of staging. Univariate and multivariate analysis assessed the impact of factors on quality of staging. Survival was also compared according to the initial surgical access. Data were computed and analysed using SPPS 7.5 and STATA 8. RESULTS: 118 cases have been included, 48 (41%) have been operated on by laparoscopy, 54 (45%) by laparotomy and 16 (14%) had a conversion. A conservative treatment has been done in 57% of patients, with increased frequency in case of laparoscopy (P<0.05) and in aged patients (P<0.001). A tumor rupture occurred in 9% of cases, without difference between accesses (P=0.1). A bag was used for the specimen delivery in only 40% of cases of laparoscopy. Most of patients (73%) had an incomplete staging. Year of treatment, and a radical treatment were associated with a better staging. Survival curves showed no detrimental effect of laparoscopy. DISCUSSION AND CONCLUSION: Despite an incomplete staging, this series does not show any detrimental effect of laparoscopy on the outcome of early BOT.

Vaginoscopic hysteroscopy permits to avoid several painful gestures of classical office hysteroscopy. The aim of this article is to describe the advantages such vaginoscopic approach. Six studies were thus selected, dealing with vaginoscopic hysteroscopy. The diameter of the hysteroscope, always a rigid one, was between 3.5 and 5 mm, and CO(2) or saline infusions were indifferently used. Failure rate is inferior to 5%. One study, comparing pain induced by vaginoscopic versus classical hysteroscopy, concluded that vaginoscopic approach was less painful.

The aim of this study was to compare staging by laparoscopy and laparotomy, and to compare survival in patients with laparoscopy versus laparotomy as the first surgical access. We conducted a retrospective analysis of patients with stage I ovarian cancer treated surgically between 1985 and 2001, and we included those patients with stage I epithelial cancer for whom follow-up data were available. For each patient, we recorded whether initial surgical staging was by laparoscopy or by laparotomy, the procedures done at initial staging surgery, and the outcomes. The data were evaluated by analysis of variance, Chi-square test or Fisher's exact test, logistic regression, Cox model, and log-rank test, using SPSS 7.5 and STATA. Initial staging was by laparoscopy in 34 patients, laparotomy in 114 patients, and laparoscopy converted to laparotomy in 30 patients. In the laparotomy group, patient age was significantly greater and tumor size significantly larger, as compared to the laparoscopy group. Staging after first surgery was often inadequate; most notably para-aortic lymph node dissection was done in 0% of laparoscopy patients, 18% of laparotomy patients, and 33% of conversion patients. Restaging surgery has been indicated in 88% of laparoscopy patients, 48% of laparotomy patients, and 46% of conversion ones. After a mean follow-up of 40 months, survival rates were not significantly different among the three patient groups. No deleterious influence of laparoscopy as first surgical access was detected by univariate or multivariate analysis. Despite of inaccurate radicality and staging during initial laparoscopy, this study found no harmful influence of laparoscopy as first initial access on outcomes of patients with stage I ovarian cancer.
