Is laparoscopy still the gold standard in infertility assessment? A comparison of fertiloscopy versus laparoscopy in infertility. Results of an international multicentre prospective trial: the 'FLY' (Fertiloscopy-LaparoscopY) study.

BACKGROUND: The aim of this prospective multicentre study was to compare the two endoscopic techniques of laparoscopy and fertiloscopy in routine evaluation of the pelvis in infertile women. METHODS: A total of 92 women was selected in 14 University Hospitals to undergo fertiloscopy followed by transabdominal laparoscopy by a team of two surgeons in each hospital. RESULTS: A high degree of concordance was observed between these two techniques, in that if fertiloscopy did not detect any abnormalities, this was also confirmed by laparoscopy. Discordance was observed in similar numbers of cases: eight after laparoscopy and nine after fertiloscopy. The diagnostic index for fertiloscopy and laparoscopy was calculated; sensitivity (86 and 87% respectively) and negative predictive value (64 and 67% respectively) were similar. The kappa index was also calculated for each of the six structures/regions (right/left tube; right/left ovary; peritoneum of pouch of Douglas; posterior uterus), and concordance (0.78 to 0.91) was considered almost complete. CONCLUSIONS: These results confirm fertiloscopy as a minimally invasive safe procedure that may be considered as an alternative to diagnostic laparoscopy in the routine assessment of women without clinical or ultrasound evidence of pelvic disease. On the basis of the additional advantages of fertiloscopy, namely salpingoscopy or microsalpingoscopy, it is considered that fertiloscopy could replace laparoscopy as a routine procedure in such women.

[Methods for laparoscopy: open laparoscopy or closed laparoscopy? Attitude of the French Central University Hospital].

Standard technique of insufflation of the pneumoperitoneum includes the use of the Veress needle followed by the blind insertion of the umbilical trocar. To avoid blind trocar insertion, numerous techniques for the creation of the pneumoperitoneum have been reported: open-laparoscopy and micro-laparoscopy are the two major alternative methods used in France. The aim of this study was to determine the incidence of open-laparoscopy in the French departments of Gynecology of the University Hospitals. With this purpose, we send to each chief of the department of Gynecology in a University Hospital a simple questionnaire about the methods used in his division for the creation of pneumoperitoneum. Sixty-three chiefs of department have answered to the questionnaire. Thirteen (21%) answered they only used conventional technique. Ten (16%) departments perfonned always open-laparoscopy, and 40 University Hospital mostly used conventional technique combined sometimes when the initial procedure of insufflation failed or seems to be too dangerous (Obesity, previous laparotomy...). Five surgeons used a lateral rather than umbilical insertion for the openlaparoscopy in case of previous laparatomy. Fifteen departments used micro-laparoscopy since 1995, and mostly since 1998. We conclude that no simple technique can claim to be overwhelmingly superior. It seems tous dangerous to impose or to condemn any methods. Keeping the choice of the technique, learning security and organizing the survey of our results remain our recommendations for the approaches of abdominal entry for laparoscopy.

Complications during set-up procedures for laparoscopy in gynecology: open laparoscopy does not reduce the risk of major complications.

OBJECTIVE: To compare the risk of major complications during the set-up procedures for laparoscopy according to whether the classic technique (creation of the pneumoperitoneum followed by introduction of the optics trocar) or open laparoscopy is used. METHODS: Comparison was made of two retrospective series each carried out in a department promoting one of the two techniques. The setting was a university-affiliated hospital. Two groups of patients were compared: group A, classic laparoscopy, n = 8324; group B, open laparoscopy, n = 1562. We investigated the set-up procedures of operative laparoscopy according to the rules of classic or open laparoscopy. RESULTS: The risk of failure requiring conversion to laparotomy is significantly higher in the group of patients who underwent open laparoscopy [three cases (0.19%) vs. 0 case (0.0%); p = 0.004]. The risk of major complications is comparable in the two groups [group A, four cases (0.05%) vs. group B, three cases (0.19%); p = 0.08]. In the classic laparoscopy group there were four major complications: one injury to the aorta and three bowel injuries. In the open laparoscopy group there were three major complications: two bowel injuries and one postoperative occlusion. CONCLUSIONS: Open laparoscopy does not reduce the risk of major complications during the set-up procedures for laparoscopy. Randomized prospective trials are indispensable for comparing the risks involved with the classic technique and those of open laparoscopy.

Utility of staging laparoscopy in subsets of biliary cancers : laparoscopy is a powerful diagnostic tool in patients with intrahepatic and gallbladder carcinoma.

BACKGROUND: The aim of this study was to evaluate the utility of staging laparoscopy in patients with biliary cancers in the era of modern diagnostic imaging. METHODS: From September 2002 through August 2004, 39 consecutive patients with potentially resectable cholangiocarcinoma underwent preoperative staging laparoscopy before laparotomy. Preoperative imaging included ultrasonography and triphasic computed tomography for all patients and magnetic resonance cholangiography in 35 patients (90%). Final pathological diagnosis included 20 hilar cholangiocarcinomas (HC), 11 intrahepatic cholangiocarcinomas (IHC), and eight gallbladder carcinomas (GBC). RESULTS: During laparoscopy, unresectable disease was found in 14/39 patients (36%). The main causes of unresectability were peritoneal carcinomatosis (11/14) and liver metastases (5/14). At laparotomy, nine patients (37%) were found to have advanced disease precluding resection. Vascular invasion and nodal metastases were the main causes of unresectability during laparotomy (eight out of nine). In detecting peritoneal metastases and liver metastases, laparoscopy had an accuracy of 92 and 71%, respectively. All patients with vascular or nodal involvement were missed by laparoscopy. For prediction of unresectability disease, the yield and accuracy of laparoscopy were highest for GBC (62% yield and 83% accuracy), followed by IHC (36% yield and 67% accuracy) and HC (25% yield and 45% accuracy) CONCLUSION: Staging laparoscopy ensured that unnecessary laparotomy was not performed in 36% of patients with potentially resectable biliary carcinoma after extensive preoperative imaging. In patients with biliary carcinoma that appears resectable, staging laparoscopy allows detection of peritoneal and liver metastasis in one third of patients. Both vascular and lymph nodes invasions were not diagnosed by this procedure. Due to these limitations, laparoscopy is more useful in ruling out dissemination in GBC and IHC than in HC.

Peritoneal response to a septic challenge. Comparison between open laparotomy, pneumoperitoneum laparoscopy, and wall lift laparoscopy.

BACKGROUND: Laparoscopic surgery has a lower incidence of surgical infection than open surgery. Differential factors that may modify the bacterial biology and explain this finding to some extent include CO(2) atmosphere, less desiccation of intraabdominal structures, fewer temperature changes, and a better preserved peritoneal and systemic immune response. Previous data suggest that the immune response and acute phase response are better preserved after laparoscopy. Therefore, we designed a study to evaluate the early peritoneal response to sepsis in an experimental peritonitis model comparing open surgery with CO(2) and abdominal wall lift laparoscopy. METHODS: The study subjects comprised 360 mice distributed into the following four groups: group 1, n = 72 (controls); group 2, n = 96 (open surgery), 2-3 cm laparotomy, with abdominal cavity exposed to the air for 30 min; group 3, n = 96, CO(2) laparoscopy (5 mmHg pneumoperitoneum) for 30 min; group 4, n = 96, wall lift laparoscopy for 30 min. Intraabdominal contamination in the four groups was induced with 1 ml of E. coli suspension (1 x 10(4) CFU/ml) 10 min before abdomen closure. Peritoneal fluid and blood samples were obtained 1.5, 3, 24, and 72 h after surgery, and TNF, IL-1, and IL-6 were measured (via ELISA), as well as quantitative culture. RESULTS: The number of CFU (colony-forming units) obtained in peritoneal fluid and positive blood culture rates were significantly lower in the laparoscopic groups than in the open group. IL-1 peritoneal levels were significantly lower after 24 h and 72 h in the laparoscopy groups. IL-6 levels decreased sharply in the laparoscopy groups at 24 h and 72 h. There were no differences between the two types of laparoscopy models (CO(2) and wall lift). CONCLUSIONS: Peritoneal response to sepsis is better preserved after laparoscopy than after open surgery. CO(2) does not seem to influence bacterial growth. According to these findings, laparoscopy entails less local trauma and better preserved intraabdominal conditions.

[Retrospective comparative study of 600 appendectomies carried out by laparotomy (Mac Burney) or laparoscopy. A plea for laparoscopy].

The authors report the results of a retrospective study comparing 305 appendectomies by laparotomy (performed in 1988-1989) with 295 appendectomies by laparoscopy (1990-1991). The appendectomy was performed by the "out" technic in 98% of cases of laparoscopy. The two populations are similar. There was no mortality. There was 1% of conversion, 1.4% of incidents and no major accident after laparoscopy. The post-operative course was smooth in 88.2% of cases after laparotomy and in 98% after laparoscopy. A treatment for pain was necessary in 98% of cases after laparotomy and only 45.4% after laparoscopy. The rates of parietal complications, intra-abdominal complications and reinterventions were respectively 10.8%, 1% and 2.4% after laparotomy and 0%, 2.4% and 2.4% after laparoscopy. The mean hospital stay was 7 days after laparotomy and 4 days after laparoscopy. In conclusion, laparoscopy appears superior to laparotomy for performance of an appendectomy: it allows better abdominal exploration, more simple and shorter post-operative course and suppresses parietal complications provided that it is performed by a surgeon with great experience of laparoscopy and respects classic principles of digestive surgery.

The treatment of failed laparoscopy using open laparoscopy.

There are over 300,000 laparoscopies done each year in the United States, and about 60,000 in England. "Failed laparoscopies" in which the procedure cannot be accomplished, has variously been reported in 0.043-4.3/1000 cases. A reasonable estimate of failed laparoscopy of 0.75% suggest that up to 2250 cases of "failed laparoscopy" occurs each year in the USA and 450 in UK. The translation of such failures into the personal experience of patients and the overall cost is staggering despite the fact that failures are not common. Three cases of "failed laparoscopy" in which the procedure was easily completed by open laparoscopy are reported and discussed. Familiarity with the techniques of open laparoscopy could virtually eliminate the incidence of failed laparoscopies.

Three-dimensional laparoscopy. Gadget or progress? A randomized trial on the efficacy of three-dimensional laparoscopy.

BACKGROUND: This study was designed to compare conventional laparoscopy with three-dimensional (3-D) laparoscopy. METHOD: Thirty candidates, 20 inexperienced and 10 experienced in operative laparoscopy, executed standardized exercises on a pelvitrainer. The candidates were randomized to two groups. Group A executed the exercises first with the conventional and then with the three-dimensional system. Group B accomplished the exercises in the reverse sequence. At the end of the exercises, the candidates answered specific questions about the two systems. RESULTS: A total of 21 h 6 min 6 sec of laparoscopic exercises were analyzed-10 h 8 min 1 sec with the conventional and 10 h 58 min 5 sec with the three-dimensional system (p = 0.38). Group A required 12 h 26 min 56 sec to perform all the exercises. There was no statistically significant difference from group B, where the candidates needed 8 h 39 min 10 sec (p = 0.14). Neither were there any differences in the number of failed attempts between the two groups. There were also no statistical difference when the results obtained from the candidates without experience in laparoscopy and the participants experienced in operative laparoscopy were analyzed separately. Both the inexperienced and the experienced candidates became tired earlier, had more headaches, and needed extra time to adapt to the 3-D system. CONCLUSION: When analyzed in a standardized fashion, 3-D laparoscopy does not have any significant advantages over conventional laparoscopy.

[The diagnosis of liver cirrhosis: a comparative evaluation of standard laparoscopy, mini-laparoscopy and histology].

BACKGROUND: The superiority of laparoscopy with guided biopsy over biopsy alone is established. It is still uncertain if this is also true for midi-/ and mini-laparoscopy. AIM: The aim of this study was to determine the diagnostic gain of laparoscopic-guided biopsy for standard laparoscopy and the use of midi-/mini-laparoscopies. Characteristics of the liver biopsies were investigated with regard to a missed diagnosis of cirrhosis. METHODS: In a consecutive series of 425 patients clinical, laparoscopic and histological findings were investigated. The length and fragmentation of the liver biopsies were investigated with regard to a missed diagnosis of cirrhosis. RESULTS: The sensitivity of laparoscopy in the diagnosis of cirrhosis was 96 %, that of histology 68 %. The sensitivity of histology alone was especially low in macronodular cirrhosis. The sensitivity of both laparoscopy and histology improved from Child A to C. When cirrhosis was apparent, liver biopsies were shorter and more frequently fragmented. However, the diagnosis of cirrhosis was independent of these parameters. CONCLUSION: Mini-laparoscopy may replace standard laparoscopy and appears to be superior compared with histology alone.

[Gil-Vernet anti-reflux operation by united application of television laparoscopy and vesicourethral laparoscopy].

OBJECTIVE: To discuss the possibility of united application of television laparoscopy and vesicourethral laparoscopy in Gil-Vernet operation. METHODS: The animal model of vesicourethral reflux (VUR) was established using rabbits. The Gil-Vernet operation was carried out by united application of television laparoscopy and vesicourethral laparoscopy. RESULTS: The VUR model was successfully established in 13 rabbits, and the reflux was successfully cured by microsurgical methods. CONCLUSIONS: This method had the advantages of television laparoscopy, vesicourethral laparoscopy and the Gil-Vernet such as no dissection of inner part of ureter-bladder wall, small wound, less bleeding, fast recovery, less complication and possible repetitive operation. It can be used in ill children with VUR.

Anesthesia for laparoscopy with emphasis on outpatient laparoscopy.

Laparoscopy has developed extremely rapidly and is currently applicable to virtually every surgical subspecialty. Most of the experience is with gynecologic laparoscopy, which has been performed for many years. Some of these procedures are simple and brief, with minimal gas insufflation. In these cases, respiratory compromise is limited, and spontaneous ventilation appears acceptable. Such procedures therefore can be performed with the patient under local or regional anesthesia, or using the LMA with general anesthesia, because the risk of aspiration is small. As laparoscopy has developed, more prolonged operations have become possible, but these normally require general anesthesia, controlled ventilation, and tracheal intubation. More sophisticated laparoscopic surgery has reduced postoperative morbidity, shortened hospital stays, and moved many procedures into the outpatient arena. These newer laparoscopic operations present many challenges, especially in the provision of adequate analgesia and the minimization of PONV. Analgesia should be multimodal, using local anesthesia and NSAIDs as first-line therapy. This combination may be sufficient for more minor procedures, and the elimination of opioids helps to reduce PONV. For more extensive operations, opioids also are required, but should not be the mainstay of analgesia. PONV should be treated effectively whenever it occurs, with consideration given to the use of prophylactic antiemetics in especially high-risk groups. Laparoscopic surgery clearly offers significant advantages in many cases. Although this technology can make some procedures technically possible on an outpatient basis, the morbidity following operations such as laparoscopic cholecystectomy is considerable. The ever-greater cost savings from the expansion of outpatient surgery is being achieved at the expense of patient discomfort and dissatisfaction. Extended care (23 h) could be a better option in some circumstances. The future will see further developments in laparoscopic surgery. Microlaparoscopy permits simple procedures to be performed with minimal analgesia and sedation in an office setting. At present, this technology allows only diagnostic and minor operative procedures, the stage at which conventional laparoscopy was in the early 1980s. Further developments in optical fibers could reduce the requirements for general anesthesia for other operations and substantially reduce postoperative morbidity. Until then, laparoscopy continues to present many challenges.

A randomized, prospective comparison of pain after gasless laparoscopy and traditional laparoscopy.

STUDY OBJECTIVE: To compare pain after laparoscopic tubal ligation by gasless laparoscopy versus carbon dioxide (CO2) pneumoperitoneum. DESIGN: Prospective, randomized, single-blind comparison (Canadian Task Force classification I). SETTING: Private obstetric-gynecology hospital associated with a university resident teaching program. PATIENTS: Women age 21 to 42. INTERVENTION: Single-puncture laparoscopic tubal ligation was performed with a silicone elastomer band. Gasless laparoscopy was performed with a Laprolift and traditional laparoscopy with CO2 pneumoperitoneum. Postoperative pain in the shoulder and periumbilical and lower pelvic regions was measured by visual analog scale on the day of surgery and postoperative days 1, 2, 3, 7, and 14. MEASUREMENTS AND MAIN RESULTS: Of the 67 patients, 54 provided visual analog scales for analysis, 30 in the gasless group and 24 in the traditional group. No statistical difference was seen in scores for shoulder, periumbilical, and pelvic pain between techniques. CONCLUSION: Patients undergoing gasless laparoscopy and traditional laparoscopy experience similar postoperative pain.

Laparoscopy in surgical treatment of vaginal aplasia: laparoscopy-assisted colpopoiesis and perineal hysterectomy with colpopoiesis.

OBJECTIVE: To optimize methods of surgery in patients with malformations of the genitalia. METHODS: Comparative evaluation of effectiveness of reconstructive plastic operations for malformations of uterus and vagina, performed by conventional methods or via laparoscopy. RESULTS: Laparoscopy permits identification of the pelvic peritoneum plus opening it and using the most mobile portion to create the vaginal fornix. In patients with vaginal and cervical aplasia and non-communicating functional rudimentary uterus, laparoscopy assists hysterectomy performed by the vaginal approach, as well as the last step of colpopoiesis. CONCLUSIONS: Laparoscopy significantly facilitates the procedure, reduces operating time and risks, and makes the operation available to the wide range of surgeons skilled in laparoscopy.

Effect on negative laparoscopy rate in chronic pelvic pain patients using patient assisted laparoscopy.

OBJECTIVE: To determine the value of Patient Assisted Laparoscopy (PAL) in the diagnosis of pelvic pain. METHODS: One hundred patients with pelvic pain were assessed by the procedure of Patient Assisted Laparoscopy to determine the cause of chronic pelvic pain. RESULTS: Of the 100 patients with pelvic pain, 12 patients were not assessed due to technique failure, which included reaction to the carbon dioxide gas, inadequate visualization due to abdominal adhesions or failure to enter peritoneum. Of the remaining 88 patients, 61 had endometriosis; 16 had adhesions not associated with endometriosis; five had hernias; one had occult bowel cancer; one pseudo-stone from previous cholecystectomy; one had pain as a result of staples used at hysterectomy and one patient had chronic Crohn's disease. Two patients had no demonstrated interabdominal cause for their symptoms. CONCLUSION: In contrast to the well published rate of 35% negative laparoscopy in those patients with pelvic pain when examined under general anesthetic, Patient Assisted Laparoscopy decreased the negative laparoscopy rate to less than 3%. This methodology was also of benefit in giving the patient a better understanding of the cause of her pain and the need for therapy.

[Laparoscopy and re-laparoscopy in the diagnosis and treatment of postoperative complications].

Experience of repeated laparoscopic surgeries in early and late postoperative period in 112 patients is analyzed. In early postoperative period repeated laparoscopy was performed in 75 patients for prevention, diagnosis and treatment of postoperative complications. In 54 patients repeated laparoscopy was carried out for programmed control for pathologic process. Laparoscopic surgery for diagnosis and treatment of postoperative complications was performed in 27 patients. In this group complications were seen in 2 patients. Technical features of repeated laparoscopy are demonstrated. Laparoscopic surgeries after laparotomic and laparoscopic operations are a good component of complex treatment and prophylaxis of severe complications in abdominal surgery. Prior performed abdominal operation is not contraindication for laparoscopy.

Postoperative adhesion development after operative laparoscopy: evaluation at early second-look procedures. Operative Laparoscopy Study Group.

To assess the issue of the frequency and severity of adhesion reformation and de novo adhesion formation after operative laparoscopy, this multicenter collaborative report of early second-look procedures after operative laparoscopy was initiated. Sixty-eight subjects underwent operative laparoscopic procedures including adhesiolysis, followed by a second operative procedure within 90 days. The total mean adhesion score decreased from 11.4 +/- 0.7 at the initial operative procedure to 5.5 +/- 0.4 at the second-look procedure, a decrease of 52%. At the time of the second-look procedure, 66 of 68 women (97.1%) had pelvic adhesions. Adhesion reformation occurred in 66 of 68 women and at 230 of 351 sites (66%) at which adhesions were lysed. Despite this high incidence of adhesion reformation, de novo adhesion formation after operative laparoscopy occurred in only 8 of 68 women (12%) and at 11 of 47 available sites in these 8 women. We conclude that adhesion reformation is a frequent occurrence after operative laparoscopy; however de novo adhesion formation appears to occur much less frequently.

Diagnostic laparoscopy v. combined screening laparoscopy and timed follicle aspiration for in vitro fertilisation.

Results from ovulation induction and laparoscopic oocyte retrieval for in vitro fertilisation and embryo transfer were compared in two groups of patients to determine whether oocyte retrieval subsequent to diagnostic laparoscopy had specific advantages over combined screening laparoscopy and timed follicle aspiration. There were no statistically significant differences in any of the factors investigated in the two groups. This study was useful in demonstrating firstly that there are no absolute criteria for selection of patients for either diagnostic or combination laparoscopy. Secondly, the procedure of choice is a combined screening laparoscopy and timed follicle aspiration if a patient is willing to accept a failure rate of 7.4% (2/27 in this study) due to ovarian inaccessibility.
