Development and validation of a home-based, mirrored, gynecologic laparoscopy trainer.

STUDY OBJECTIVE: To develop and evaluate the usefulness of a home-based laparoscopy practice tool in terms of skills acquisition and practice pattern. DESIGN: Six mirrored laparoscopy trainers were designed and built. Participants were enrolled in a prospective randomized controlled trial and performed a series of skills with a video-endoscopic training tower and laparoscopic training box in timed pre- and post-tests over 5 weeks. Control and experimental cohorts practiced skills tests in different settings with different equipment. Data analysis used the t test and Wilcoxon rank-sum test. Analysis of variance/analysis of covariance models were used for independent variables. (Canadian Task Force classification I.) SETTING: Midwestern tertiary care teaching hospital. PARTICIPANTS: Third-year medical students rotating through their obstetrics and gynecology clerkship. INTERVENTIONS: Control cohort participants (n = 13) practiced the skills in the video-endoscopic laboratory while the experimental cohort (n = 13) received mirrored training boxes and practiced at home. MEASUREMENTS AND MAIN RESULTS: Both groups demonstrated significant improvement, with a trend favoring the control group (p = .08). Randomization group and number of practice sessions were significant variables favoring the control group and experimental group, respectively. CONCLUSION: Home-based practice on a mirrored laparoscopy trainer improves hand-eye coordination in inexperienced surgeons and results in more frequent practice.

A laparoscopy-assisted surgical approach to esophageal carcinoma.

BACKGROUND: Surgical resection is the treatment of choice for esophageal carcinoma. Over the past decade, laparoscopy has proven an accurate staging modality for detecting peritoneal carcinosis and small metastatic liver deposits unsuspected at preoperative investigation. This has led to a change in surgical strategy in up to 20% of patients. In addition, by means of laparoscopic techniques, it is possible to mobilize the stomach and perform a safe transhiatal mediastinal dissection at least up to the level of the inferior pulmonary veins. PATIENTS AND METHODS: Laparoscopy-assisted esophagectomy was attempted in 43 patients over the past 3 years. The esophagectomy was performed via laparoscopy combined with right thoracotomy (group A) or with left cervicotomy and transmediastinal endodissection (group B). RESULTS: The overall conversion rate to laparotomy was 11.6%. No hospital deaths occurred. The morbidity rate was 20% in group A and 30.7% in group B. The mean hospital stay was 11 in group A and 10 days in group B. Five patients died between 11 and 19 months after surgery with recurrent disease. No port-site metastases were recorded during follow-up. CONCLUSIONS: This approach has proven feasible and safe in the medium-term follow-up. Further experience and a longer follow-up are needed to assess the impact of these procedures on long-term survival.

Anterior resection of rectal cancer through a one hand-size incision with or without laparoscopy: proposal of one hand-size incision surgery (OHaSIS).

BACKGROUND: One hand-size incision surgery (OHaSIS) is a surgery that is carried out through one hand-size incision with or without laparoscopy. Safety, feasibility and recovery advantage of the anterior resection of rectal cancer by the OHaSIS were studied. STUDY DESIGN: Nineteen consecutive patients with rectal cancer, consisting of seven rectosigmoid, six upper rectal, and six lower rectal cancers, were treated with anterior resection, including seven high, six low, three super-low, and three partial intersphincteric resections, through a suprapubic longitudinal one hand-size incision. The initial 11 patients were treated in combination with laparoscopy and the following eight patients were treated without laparoscopy. RESULTS: All anterior resections with mesorectal excision were completed in a safe manner with acceptable operative time (average 245 min), blood loss (average 280 g), and postoperative complications without any elongation of the initial incision. When compared with 12 previous high and low anterior resections by conventional open surgery (OS), the 13 high and low anterior resections by the OHaSIS showed equivalent operative time, blood loss, anastomotic procedures of single stapling, lymph node numbers dissected, surgical margin of the anal side of the tumor, and complications. Moreover, analysis of perioperative parameters for surgical invasiveness, including a body temperature >37 degrees C, days of bed rest, and days of use of parenteral narcotics, revealed a recovery advantage in the OHaSIS group compared with that in the OS group. CONCLUSIONS: These results suggest that anterior resection for patients with rectal cancer by the OHaSIS is safe, feasible, and less invasive than conventional OS, and has sufficient operative performance. Although the survival benefit and recurrence rate by this approach must be ensured in a future trial, we would like to propose the new concept of OHaSIS for treating rectal cancer.

Laparoscopy versus dorsal lumbotomy for ureteropelvic junction obstruction repair.

PURPOSE: Laparoscopic pyeloplasty offers similar success rates compared to open surgery. However, the advanced laparoscopic skills required may limit its widespread application. In select patients the dorsal lumbotomy approach can provide similar postoperative advantages to minimally invasive surgery. We analyze the perioperative management of laparoscopy vs dorsal lumbotomy for the repair of ureteropelvic junction obstruction. MATERIALS AND METHODS: In a retrospective review 13 patients who underwent dorsal lumbotomy pyeloplasty were compared to 19 patients who underwent laparoscopic pyeloplasty between 1998 and 2003. Preoperative confirmation of obstruction was obtained through excretory urogram or renal Lasix scan. All 13 patients undergoing dorsal lumbotomy had a dismembered pyeloplasty. Of the 19 laparoscopic cases 16 had a dismembered pyeloplasty and 3 had a Fenger procedure. Average followup was 12 months for the open group and 13.3 months for the laparoscopic group. Postoperative results were evaluated with excretory urogram or renal Lasix scan as well as subjective outcomes by the patients. RESULTS: Operative time was slightly longer for the laparoscopy group at 231 minutes vs 200 minutes. Estimated blood loss and postoperative morphine requirements were also similar. Hospital stay was 3.3 days for the dorsal lumbotomy group compared to 2.4 for the laparoscopy group. The overall success rate for the laparoscopic group was 94.7% compared to 100% for the dorsal lumbotomy group. Each group had 1 complication, paresthesia of anterior/medial thigh that resolved by 6 months. CONCLUSIONS: Our preliminary results show that a dismembered dorsal lumbotomy pyeloplasty is comparable to laparoscopic dismembered pyeloplasty with regard to intraoperative and postoperative hospital course.

Incidence of occult inguinal and Spigelian hernias during laparoscopy of other reasons.

BACKGROUND: A true incidence of occult inguinal and Spigelian hernias in adult population is unknown. The frequency of incipient hernias was studied during laparoscopy of other abdominal diseases. METHODS: The 201 laparoscopic procedures included 104 cholecystectomies, 55 fundoplications, 36 diagnostic, and 6 miscellaneous operations. There were 133 females and 68 males with a mean age of 53 +/- 14 years. The orifices of all inguinal and Spigelian hernias were carefully recorded at the beginning of laparoscopy by using 30 degrees optic. RESULTS: The overall frequency of unexpected hernias was 43 of 201 (21%) including 36 (18%) inguinal hernias, 5 (2%) Spigelian hernias and 2 (1%) ventral hernias. The number of hernias was higher in males than in females (P = .003). The most common finding was indirect inguinal hernia in 27 (13%) subjects. Usually hernia orifices were insignificant and only 5 of 201 laparoscopic hernioplasties were undertaken without any complications. CONCLUSIONS: Occult hernia orifices are commonly found in laparoscopic operation. Usually the defects are asymptomatic and hernioplasty is not needed. Herniation of Spigelian fascia is rare (<2%) in adults during laparoscopy.

[Ultrasonographic laparoscopy of the liver].

SITUATION: In spite of recent progress in medical imagery, the findings of preoperative investigations of the liver are not always accurate and precise. Since the development of surgical laparoscopy, advantages of the laparoscopic examination are associated with advantages of laparoscopic ultrasonography. OBJECTIVE: The purpose of this work is to report the technique of staging laparoscopy with laparoscopic contact ultrasonography in the intraoperative assessment of patients with liver tumors, and to analyse its impact on the selection of patients for hepatic resection with curative intent. METHODS: The basic exploration follows at first portal branches and then hepatic veins. During the course of vascular exploration, the corresponding liver parenchyma is examined. A mobilization of the probe with clockwise or anticlockwise rotation movements allows full exploration of the liver. RESULTS: The association of laparoscopic examination and laparoscopic ultrasonography allows to localize with accuracy malignant and benign lesions and to perform ultrasound guided biopsy. Liver tumors not visible on preoperative imagery may be identified, relationships with adjacent vessels and presence of tumoral thrombi in major vascular structures may be assessed. Resectability of the liver tumors is at the best specified. CONCLUSION: Staging laparoscopy with laparoscopic ultrasonography improves selection of patients for liver resection and facilitates choice and performance of the most appropriate resection.

[Evaluation of pancreatic cancer by combined laparoscopy and echolaparoscopy].

STUDY AIM: This prospective study was undertaken to evaluate the efficiency of staging laparoscopy associated with laparoscopic ultrasonography in the assessment of tumoural extension and surgical resectability in patients with carcinoma of the pancreatic head. PATIENTS AND METHODS: From June 1995 to March 1997, 26 consecutive patients (11 male and 15 female patients), with a mean age of 62.5 years, were included in this study. The lesion was located in the pancreatic head with jaundice. Four staging methods were used: percutaneous ultrasonography (n = 26) computed tomography (n = 26), endoscopic ultrasonography (n = 26). The assessment of resectability by each procedure was verified by surgical exploration and histologic examination. RESULTS: Results of percutaneous ultrasonography and computed tomography were similar, predicting unresectability in 50% of the patients. Endoscopic ultrasonography performed in the 16 patients without visible metastases according to the previous procedures predicted surgical resectability in seven patients only. With staging laparoscopy associated with laparoscopic ultrasonography, undiscovered metastases were found and unresectability was predicted in 21 patients out of 26; the sensitivity was 100% for liver metastases, peritoneal metastases and vascular involvement, 90% for lymph node involvement and 88% for diagnosis of the primitive lesion. A Whipple procedure was performed in five patients and a palliative bypass in all the other patients except one. An unnecessary laparotomy was avoided in 12 patients. CONCLUSIONS: Staging laparoscopy associated with laparoscopic ultrasonography is superior to all other staging methods. It should be the first step of a potentially curative surgical treatment (five cases only in this series) or of a palliative bypass. Laparotomy was avoided in 12 cases.

[A survey of the contralateral inguinal hernial sac in infants less than 1 year of age using laparoscopy with anatomic verification using peritoneal radiography or surgery].

STUDY AIM: The aim of this prospective study was to evaluate the laparoscopic diagnosis of contralateral patent processus vaginalis in children with unilateral inguinal hernia. PATIENTS AND METHOD: Between November 1995 and February 1998, 91 consecutive children (78 boys, 13 girls) under the age of 1 year were operated on for a unilateral inguinal hernia. A contralateral hernia was diagnosed by a laparoscopy through the inguinal hernia sac before ligation. Results of this technique were correlated with those of herniography (79 cases) or with inguinal exploration (12 emergency). RESULTS: Laparoscopy was performed in 88 patients. Laparoscopy was impossible in three cases: one inguinal sac too thin, two cases of ectopic testis in the inguinal canal. Sensitivity was 73% and specificity 92%. The only complication arising from the procedure was wound infection in two patients. CONCLUSION: This method is a simple, safe and accurate procedure in order to select children for contralateral surgical exploration.

A four-year experience with laparoscopy in the management of appendicitis.

BACKGROUND: The study was conducted to determine the influences of laparoscopy in the management and outcome of patients with appendicitis. METHODS: A retrospective analysis of 154 consecutive patients who were treated for suspected appendicitis. The pre-operative diagnosis included appendicitis, right lower quadrant pain of unknown etiology, and generalized peritonitis. RESULTS: Laparoscopy was used in 108 patients, including 70 laparoscopic appendectomies (LA) and 31 LAs converted to open appendectomy (OA). Forty-six patients had OA. The average operating time for LA was 74.3 minutes and 48.8 minutes with OA. Postoperative complications for LA (7%) included 1 trochar wound hemorrhage, 2 wound infections, and 2 intra-abdominal sepsis; and for OA (9%) were 1 post-operative intra-abdominal hemorrhage, 4 wound infections, 1 wound dehiscence, and 1 intra-abdominal sepsis. Post-operative stay for LA averaged 2.5 days and for OA averaged 4.5 days (P = .0049). LA patients had a considerably faster return to work and/or normal activity than OA patients (P = .00065). CONCLUSIONS: Laparoscopy influenced the management of 29% of patients presenting with suspected appendicitis. LA resulted in shorter hospitalization and a more rapid return to work and/or normal activity than OA.

Treatment of female infertility due to tubal obstruction by operative laparoscopy.

The advent in recent years of safe endocoagulation (thermocoagulation within the abdomen) has permitted operative laparoscopic treatment of the tubal factor in infertility in selected cases. This paper reviews the results of operative laparoscopy in 223 cases treated for infertility between 1971 and 1976. Tubal occlusion was present in 133 patients before surgical intervention. Following operative laparoscopy, tubal patency was demonstrated in 67% on testing at the time of operation and in 12% at the first postoperative hydrotubation. In only 21% of cases was tubal patency not achieved by these methods. Those cases requiring isthmic salpingostomy, ampullary or isthmic-tubal implantation, or end-to-end anastomosis were further treated by laparotomy and microsurgery. Ninety cases of pelvic endometriosis were treated by a combination treatment of thermocoagulation, ovarian cyst resection, and the antigonadotropin agent, danazol. Ovariolysis, salpingolysis, fimbrioplasty, and salpingostomy can easily be performed using operative laparoscopy as the method of choice with a minimum of complications, shortened hospitalization time (2 days), and the potential for a repeat procedure or a follow-up laparotomy should this be necessary. The pregnancy rate following laparoscopic treatment for the correction of distal tubal occlusion was 30.5% and for endometriosis genitalis externa, 40%. These rates compare favorably with the rates following procedures involving laparotomy and microsurgery for correction of similar lesions.

Combined laparoscopy and hysteroscopy in the investigation of the ovulatory infertile female.

A previous study had demonstrated the superiority of hysteroscopy over hysterosalpingography for the detection of intrauterine lesions in infertile patients. One hundred and sixty-nine patients were examined by a combined laparoscopic and hysteroscopic technique as the means of detecting tubal, peritubal, peritoneal, or intrauterine causes of infertility. Laparoscopy was successful in 168 and hysteroscopy in 162. The rate of diagnosis by laparoscopy of 49.4% was increased to 66% when the hysteroscopic findings were included. Only one serious complication was recorded, the inadvertent visualization of an intrauterine pregnancy. Arguments are advanced for the replacement of hysterosalpingography with combined laparoscopy and hysteroscopy as the primary means of investigating the ovulatory infertile female.

Operative laparoscopy for the treatment of ovarian remnant syndrome.

OBJECTIVE: To present the technique and assess the efficacy of operative laparoscopy to manage ovarian remnant syndrome. DESIGN: Observational with a follow-up of 6 to 32 months. SETTING: Private subspecialty practice with a large referral base. PATIENTS: Thirteen women, 9 with previous bilateral salpingo-oophorectomy and 4 with previous unilateral salpingo-oophorectomy and pain on the ipsilateral side. INTERVENTIONS: Multipuncture advanced operative laparoscopy. MAIN OUTCOME MEASURES: Patient pain relief was assessed through return examinations, telephone interviews, or contact with referring physicians. RESULTS: Nine patients reported complete pain relief. One reported incomplete but satisfactory pain relief. Two required bowel resection by laparotomy to obtain pain relief, and one, despite subsequent laparotomy, had persistent pain. No intraoperative or postoperative complications were noted. CONCLUSION: Laparoscopy can be effective in managing ovarian remnant syndrome when performed by an experienced laparoscopist.

Laparoscopy diagnosis of chlamydial salpingitis using a tubal cytobrush.

This is a report of our nontraumatic technique using a tubal cytobrush for epithelial tubal cell recovery during laparoscopy diagnosis of C. trachomatis salpingitis. We performed a three-way laparoscopy in 95 women and inserted a long flexible fallopian tube brush through one of the trocars. This technique showed that it is possible to reach the infection site avoiding vaginal contamination and that sufficient tubal cells can be obtained for isolation of intracellular pathogens. The technique also allowed rapid antigen detection directly on tubal cells by IFA and C. trachomatis isolation on cell culture. Tubal scraping did not cause bleeding or adhesions as later observed in a matched group of women who underwent further laparoscopy during GIFT.

Prospective, randomized, double-blind, controlled trial of laser laparoscopy in the treatment of pelvic pain associated with minimal, mild, and moderate endometriosis.

OBJECTIVE: To assess the efficacy of laser laparoscopic surgery in the treatment of pain associated with minimal, mild, and moderate endometriosis. DESIGN: A prospective, randomized, double-blind, and controlled clinical study. SETTING: Royal Surrey County Hospital, Guildford, United Kingdom, a referral center for the laser laparoscopic treatment of endometriosis. PATIENTS: Sixty-three patients with pain (dysmenorrhoea, pelvic pain, or dyspareunia) and minimal to moderate endometriosis. INTERVENTIONS: The patients were randomized at the time of laparoscopy to laser ablation of endometriotic deposits and laparoscopic uterine nerve ablation or expectant management. Pain symptoms were recorded subjectively and by visual analogue scale. The women were unaware of the treatment allocated as was the nurse who assessed them at 3 and 6 months after surgery. MAIN OUTCOME MEASURE: Improvement or resolution of pain symptoms assessed subjectively and by visual analogue score. RESULTS: Laser laparoscopy results in statistically significant pain relief compared with expectant management at 6 months after surgery. Sixty-two and a half percent of the lasered patients reported improvement or resolution of symptoms compared with 22.6% in the expectant group. Results were poorest for minimal disease and, if patients with mild and moderate disease only are included, 73.7% of patients achieved pain relief. There were no operative or laser complications. CONCLUSIONS: Laser laparoscopy is a safe, simple, and effective treatment in alleviating pain symptoms in women with stages I, II, and III endometriosis.

Operative laparoscopy versus open abdominal surgery: a comparative study on postoperative adhesion formation in the rat model.

The aim of this study was to compare the occurrence of adhesions after a standard uterine injury inflicted by laparoscopy or by laparotomy during which microsurgical principles were observed. The cross-sectional areas of adhesions involving the uterus were assessed and the 31 rats operated upon laparoscopically were compared with the 30 rats subjected to a laparotomy. The mean area of uterine adhesions formed in the laparotomy group was 4.29 mm2 and 8.88 mm2 in the laparoscopy group. The difference was not statistically significant. The results imply that a standard tissue injury to uterine tissue, whether conducted by laparoscopy or via laparotomy, carries the same potential to induce postoperative adhesions.

Removal of surgical barriers of expanded polytetrafluorethylene at second-look laparoscopy was not associated with adhesion formation.

OBJECTIVE: To evaluate whether the surgical trauma required for the laparoscopic removal of a polytetrafluoroethylene (PTFE) surgical barrier would cause postoperative adhesions. DESIGN: Two case reports. SETTING: Tertiary academic medical center. PATIENT(S): Two women who had undergone myomectomy with placement of a PTFE surgical barrier and who were free of adhesions with the barrier in place. INTERVENTION(S): Removal of the PTFE barrier by laparoscopy 11 days after myomectomy. MAIN OUTCOME MEASURE(S): Adhesions at the site of removal of the PTFE barrier at the time of incidental laparoscopy several years later. RESULT(S): Adhesions were not present at the site of PTFE barrier removal. CONCLUSION(S): The surgical trauma required to remove PTFE barriers at early second-look laparoscopy was not associated with postoperative adhesions.

Laparoscopy versus laparotomy in the management of adnexal masses during pregnancy.

OBJECTIVE: To compare the outcome of pregnancy after operative laparoscopy or laparotomy for the management of adnexal pathology during pregnancy. DESIGN: Retrospective comparative study. SETTING: University tertiary care referral center for endoscopic surgery. PATIENT(S): Eighty-eight pregnant women who underwent 93 operations for suspected adnexal pathology at our institute. Laparoscopy was performed during the first trimester in 39 patients. The remaining 54 patients underwent laparotomy, 25 during the first trimester and 29 during the second trimester. INTERVENTION(S): Laparoscopy or laparotomy for the management of adnexal masses during pregnancy. MAIN OUTCOME MEASURE(S): Operative and postoperative maternal complications, miscarriage, congenital malformations, and newborn long-term outcome. RESULT(S): No operative or postoperative maternal complications occurred in the pregnant women who underwent laparoscopic surgery. In this group of 39 women, 5 women had a first-trimester miscarriage and 2 newborns had congenital malformations (hypospadias and cleft lip and palate). Two miscarriages occurred in the first-trimester laparotomy group, and 1 congenital malformation (transposition of the great vessels) was diagnosed in the second-trimester laparotomy group. CONCLUSION(S): Laparoscopic gynecologic surgery appears to be safe during pregnancy, although prospective controlled studies and national registries encompassing larger numbers of cases are needed.
