Traumatic Lumbar hernia (TLH) is a very rare clinical entity with about 100 cases reported worldwide. It is a difficult challenge when encountered and there is no consensus on the best management: early or delayed, open or laparoscopic. We report the clinical case of a 28-year-old man who suffered from a TLH after a 6- meter-high fall. The diagnosis was based on CT imaging showing a defect in the postero-lateral abdominal wall by disinsertion of the lumbar origin of transverse, internal and external oblique muscles. A few months after the trauma, it became gradualy more painful, the hernia was clinically increased with a large swelling on the right flank majored by valsalva. CT imaging showed herniation of the right colic flexure through the defect. Eight months after the trauma, we performed an intra-abdominal laparoscopic approach. Herniated structures were reduced and we opened the peritoneum. The defect was repaired by placing a pre-peritoneal polypropylene mesh fixed by laparoscopic staples before closing the peritoneum. The patient had an uneventful recovery. Ten weeks after the surgery the result was clinically very good. The CT scanner showed a good recovery of parietal continuity. [less ▲]

In order to prevent postoperative adhesions often present after CO 2 laser vaporization of large endometriomas, 62 patients with endometriomas greater than 3 cm diameter were treated with a new procedure. Partial cystectomy was performed using the CO 2 laser. Residual endometrial cyst was then vaporized. After laparoscopic vaporization of the interior cyst wall, a fibrin glue (Tissucol) was injected onto the vaporized area to close laparoscopically the ovarian cyst cavity. When performed, second-look laparoscopy demonstrated healing of the ovary without any periovarian adhesions. The incidence of periovarian adhesions was significantly lower (p less than 0.01) than in the group of women treated by laparoscopy and in whom the glue was not used to close the ovarian cyst cavity.

Laparoscopic myomectomy can be carried out in cases of subserosal and intramural fibroids. Laparoscopic myolysis can be proposed as an alternative to laparoscopic myomectomy in cases of large or multiple intramural fibroids in women aged over 40 or not desiring to bear more children but wishing to avoid a future hysterectomy. The authors report the technique and the long-term results in a series of 48 women with fibroids treated by myolysis. Because of the risk of bowel adhesions, further studies with another type of laser fiber are required. [less ▲]

This review will focus on the different techniques and the long-term effects of the technique called myolysis on myoma growth. Indications for myolysis are essentially pelvic pain, compression symptoms and global uterine volume in order to avoid hysterectomy. In the late 1980s, myolysis was performed laparoscopically with the help of the neodynium: yttrium aluminium garnet (Nd:YAG) laser. Later, bipolar needles were developed as an alternative to the Nd:YAG laser. Diathermy and cryomyolysis were also proposed but series are small in the literature. Very recently, myoma interstitial thermo-therapy (MITT) was performed using the diode laser and a specific optical light diffuser that is designed to transmit laser light in all directions. Laparoscopic myolysis was proved to be effective in provoking myoma shrinkage, with a dramatic decrease in size and a marked devascularization of the myoma and this technique can be proposed as an alternative to myomectomy in selected patients: only those aged >40 years or those not desiring to bear any more children.

Until now, the need for wide exposure and nonmanipulative dissection of pheochromocytoma has dictated the use of a large intraperitoneal transabdominal approach, which unfortunately results in a significant incidence of morbidity. A unilateral retroperitoneal approach guided by the refinements of new imaging techniques is less invasive but is associated with a small risk of incomplete cure. In one case report, we tested the hypothesis that laparoscopic surgery could combine the beneficial effects of both operative strategies without their respective side effects. We concluded that a laparoscopic approach combined with exclusive intraoperative infusion of nicardipine, a calcium-channel blocker, can be used to surgically remove pheochromocytoma under stable hemodynamic conditions. This provides better exposure of the anatomical structures than open surgery and allows a visual exploration of the entire abdominal cavity to exclude tumor multicentricity or ectopic sites in the case of inconclusive preoperative imaging investigations. Moreover, conversion to open surgery is always possible if needed. [less ▲]

BACKGROUND: Scientific evidence demonstrating interest in the laparoscopic approach for surgical repair of colonoscopic perforations is still lacking. The authors retrospectively reviewed the records of 43 patients who suffered from colonic perforations after colonoscopy between 1989 and 2008 in two tertiary centers in order to compare the results of the laparoscopic and the open approaches to repair. METHODS: The patients' demographic data, perforation location, therapy, and outcome were recorded from the medical charts. Forty-two patients were managed operatively (19 laparoscopies and 23 laparotomies). In three patients who underwent explorative laparoscopy, the procedure had to be converted to laparotomy due to surgical difficulties. The patients who underwent laparotomy management had a longer period between the colonoscopy and the surgery (P = 0.056) and more stercoral contaminations. RESULTS: The mean hospital stay was shorter for the laparoscopy group (P = 0.02), which had fewer postoperative complications (P = 0.01) and no mortality (NS). CONCLUSION: This series demonstrates that early laparoscopic management of colonoscopic perforation is safe. Laparoscopic management may lead to reduced surgical and psychological stress for the patient because of its low morbidity and mortality rates and shorter hospital stay. However, the procedure should be converted to a laparotomy if necessary. [less ▲]

PURPOSE: Nowadays laparoscopic colorectal surgery has demonstrated its advantages, including reduced postoperative pain, decreased duration of ileus, and shorter hospital stay. Few studies report results of laparoscopic surgery in complicated diverticulitis. This study was designed to analyze the results of laparoscopic sigmoidectomy in patients with fistulized sigmoiditis. METHODS: The authors retrospectively reviewed 16 patients who had laparoscopic sigmoidectomy for fistulized diverticulitis between 1992 and 2003 in a series of 247 laparoscopic colectomies. Eleven patients presented with colovesical, four with colovaginal, and one with colocutaneous fistulas; all were caused by sigmoiditis. The procedure always consisted of celioscopic sigmoidectomy with stapled transanal suture and, when indicated, closure of the cystic or vaginal fistula orifice. RESULTS: Mean age was 60 (range, 39-78) years. Mean number of episodes of diverticulitis before operation was three (range, 1-5). Mean time between the last episode and operation was 46 (range, 2-250) weeks. In our first three years of experience, three cases (18.7 percent) were converted to laparotomy. Reasons for conversion were the necessity for intestinal resection, splenectomy, and a wound of the anterior rectum. The mean operative time was 172 (range, 100-280) minutes. Mean hospital stay was 5.7 (range, 3-12) days. There was no mortality. Postoperative morbidity (2 patients, 12.5 percent) consisted of one pulmonary infection and one splenectomy. Long-term follow-up revealed no recurrence of diverticulitis and one incisional hernia. CONCLUSIONS: In experienced hands, laparoscopic sigmoidectomy may be a safe and effective procedure for fistulized sigmoiditis. [less ▲]

The use of laparoscopically assisted vaginal hysterectomy with or without annexectomy has been widely discussed. We report the technique of laparoscopic supracervical (subtotal) hysterectomy (LASH), which was first performed in 1990. Laparoscopic supracervical hysterectomy was carried out in a series of 36 women. The duration time was 60 min in experienced hands. There were no major complications. The feasibility and low morbidity rate of this laparoscopic approach led us to propose LASH in certain indications, particularly in cases of a uterus with multiple submucosal myomas where hysteroscopic therapy is less successful.

Reports of laparoscopy in heart graft recipients are scarce and, to our knowledge, laparoscopic colectomy has not yet been reported in heart transplant patients. The magnitude and the tolerance of the hemodynamic changes induced by pneumoperitoneum are unknown in heart graft recipients, who have a denervated heart and are "preload-dependent". The authors report the clinical courses of 2 heart graft recipients who developed acute diverticulitis without perforation or peritonitis and who underwent laparoscopic-assisted colectomy without complications.

La séduisante archéologue Lara Croft, protagoniste de la série de jeux Tomb Raider, est aujourd'hui l'une des icônes les plus célèbres du jeu vidéo, si bien qu'elle a même dépassé les limites de ce médium pour se faire connaître à un public élargi (à travers des adaptations au cinéma, en comics ou encore à travers des publicités). Toutefois, ce personnage est aussi une figure complexe qui a été reçue de manières très diverses : tantôt envisagée comme un symbole féministe (Lara Croft est une héroïne forte et indépendante, loin de la demoiselle en détresse à laquelle se cantonnaient généralement les premiers jeux vidéo), elle a aussi pu être interprétée comme une représentation caricaturale et réifiante de la femme. C'est donc d'un personnage chargé de contradictions que cette conférence propose de faire le portrait. [less ▲]

We present a summary of important computational issues and opportunities that arise from the use of semi-aggregate data (where the explanatory data for choice scenarios are not necessarily unique for each decision-maker) in discrete choice models. This data feature is commonly encountered with large transactional databases that have limited consumer information, such as itinerary choice modeling. We developed a software package called Larch, written in Python and C++, to take advantage of this kind of data to greatly speed the estimation of discrete choice model parameters. Benchmarking experiments against Stata (a commonly used commercial package) and Biogeme (a commonly used freeware package) based on an industry dataset for airline itinerary choice modeling applications shows that the size of the input estimation files are 50 to 100 times larger in Stata and Biogeme, respectively. Estimation times are also much faster in Larch; e.g., for a small itinerary choice problem, a multinomial logit model estimated in Larch converged in less than one second whereas the same model took almost 15 seconds in Stata and more than three minutes in Biogeme. For more complex discrete choice models, such as the ordered generalized extreme value model, estimation times were two seconds in Larch and four to five days in Biogeme. [less ▲]
