Laparoscopic tubal anastomosis: fertility outcome in 202 cases

Objective: To evaluate the fertility outcome after laparoscopic tubal anastomosis for reversal of sterilization.

Design: Retrospective clinical study.

Setting: A private practice affiliated with a university medical school.

Patient(s): Two hundred two women who desired reversal of tubal sterilization.

Intervention(s): Laparoscopic tubal anastomosis.

Main Outcome Measure(s): The cumulative pregnancy rate (PR) and factors that influenced the fertility outcome.

Result(s): The cumulative PR in the 186 patients for whom follow-up data were available was 60.3%, 79.4%, and 83.3% at 6, 12, and 18 months after operation, respectively. Five patients (3.2%) had ectopic pregnancies; one of these patients subsequently conceived normally. There were no statistically significant differences in the PR according to the sterilization method used, the site of the tubal anastomosis, or the length of the fallopian tube after surgery. The intrauterine PR was 87.1% (149/171) with bilateral anastomosis and 60% (9/15) with unilateral anastomosis. The PR decreased with increasing patient age (mean [±SD], 35 ± 3.6 years) but was still 70.6% (12/17) in patients aged 40–45 years.

Conclusion(s): Our findings suggest that laparoscopic tubal anastomosis is a highly successful procedure. This less invasive approach could be considered the procedure of choice in patients who desire reversal of tubal sterilization.     

Fertility outcomes following laparoscopic tubal re-anastomosis post tubal sterilisation

OBJECTIVE: To determine fertility outcomes following laparoscopic tubal re-anastomosis. DESIGN: Retrospective mail follow-up. SETTING: Specialised private gynaecological endoscopy practice. POPULATION OR SAMPLE: 19 women who underwent laparoscopic tubal reanastomosis following tubal sterilisation. MAIN OUTCOME MEASURES: Pregnancy rate and 'take home baby' rate. RESULTS: 15 (78.9%) of women became pregnant, and 13 (68.4%) carried pregnancies to viability. The mean operating time was 115 minutes (range 90-200 minutes). The mean reversal to pregnancy interval was 8.3 months (1-24 months). CONCLUSIONS: This study suggests that the pregnancy and 'take home baby' rates after laparoscopic reversal of tubal sterilisation compare favourably with open microsurgical reversal and in vitro fertilisation.     

Laparoscopic microsurgical tubal re-anastomosis: the two-stitch technique

The objective of this study was to determine the effectiveness of the two-stitch unilateral laparoscopic sterilization reversal. Thirty-three patients who had undergone unilateral laparoscopic sterilization reversal between December 2001 and October 2006 were examined. Twenty patients (60.6%) who had had laparoscopic unilateral tubal sterilization reversal achieved an ongoing pregnancy within 1 year of the operation. In vitro fertilization (IVF) was recommended to the other 13 patients, including one patient (3%) who had an ectopic pregnancy. In conclusion, in our study, the pregnancy rate after unilateral two-stitch laparoscopic tubal reversal was 60.6%. In this IVF era, tubal anastomosis will become more popular, causing fewer women to resort to IVF and experience a completely natural conception, making surgery complementary to ART. The number of surgeons skilled in laparoscopic tubal surgery must, therefore, be increased.     

Microsurgical reversal of tubal sterilization: a report on 1,118 cases

Objective: To review and evaluate a series of patients who underwent microsurgical anastomosis of previously sterilized fallopian tubes.Design: Retrospective clinical study.Setting: Tertiary care academic center.Patient(s): In the 134–month span from January 1980 to February 1991, 1,118 women were evaluated for microsurgical reversal of previous tubal sterilization.Main Outcome Measure(s): Clinical characteristics of patients, pregnancy rates (PRs), and factors influencing the outcome.Result(s): Of 1,118 patients, 633 (56.6%) had been sterilized by laparoscopic cautery. Loss of children was a leading reason for requesting tubal reversal. The mean interval between tubal sterilization and reversal was 51.9 months. Nine hundred twenty-two (82.5%) patients were followed up for > 5 years. The overall PR after microsurgical tubal anastomosis was 54.8% (505 of 922) with a delivery rate of 72.5% (366 of 505), and the estimated anatomical success rate was 88.2% (814 of 922). There was no statistically significant difference in the PR or in the interval from tubal reversal to conception among the different operative procedure groups. In addition, no statistically significant difference in the PR was observed regardless of the postoperative tubal length. However, the interval from operation to pregnancy decreased significantly as the postoperative tubal length increased. The pregnant patients (n = 505) were younger and had a longer postoperative tube than the nonpregnant patients (n = 417); these differences were statistically significant.Conclusion(s): The pregnancy rate after microsurgical reversal of tubal sterilization was not significantly correlated with the method and duration of sterilization, the operative procedure, or the postoperative tubal length.     

Outpatient laparoscopic tubal anastomosis and subsequent fertility.

OBJECTIVE: To determine the reproductive outcome of women who undergo laparoscopic tubal anastomosis. DESIGN: Observational prospective study. SETTING: University-affiliated infertility medical center. PATIENT(S): One hundred two patients seeking reversal of tubal sterilization. INTERVENTION(S): Laparoscopic tubal anastomosis was performed with a one-suture technique. MAIN OUTCOME MEASURE(s): Pregnancy rate. RESULT(S): There were 69 isthmic-isthmic, 16 isthmic-ampullary, 12 cornual-isthmic, and 5 ampullary-ampullary anastomoses. The mean operative time was 71.35 minutes. Eight patients had bilateral tubal obstruction on postoperative hysterosalpingography. Sixty-nine patients (70%) conceived. Sixty-four (65.3%) had ongoing intrauterine pregnancies, 15 (21.7%) had spontaneous abortions, and 5 (7.2%) had ectopic pregnancies. CONCLUSION(S): This study demonstrates that laparoscopic tubal anastomosis can be done safely and successfully on an outpatient basis, reducing costs and postoperative morbidity while accelerating the patient's return to normal activities.     

Laparoscopic microsurgical tubal reanastomosis: a preliminary study.

OBJECTIVE: To determine the effect of laparoscopic reversal of tubal sterilization on pregnancy rate. METHODS: Eight patients who underwent laparoscopic tubal reversal between March 1999 and 31 December 2001 were evaluated. RESULTS: Four of eight patients who had had laparoscopic tubal reversal became pregnant. Three have delivered; pregnancy in the fourth woman is ongoing. To date, the other four patients are still not pregnant. Two ofthese four cases have tubal patency but have not achieved pregnancy; in the other two cases, the operation was unsuccessful and tubal patency did not occur. CONCLUSION: In our preliminary study, the pregnancy rate was 50%.     

Fertility outcome after tubal anastomosis by laparoscopy and laparotomy

STUDY OBJECTIVE: To evaluate fertility outcome and benefit of laparoscopic tubal anastomosis compared with laparotomy. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: Eighty-one women requesting reversal of sterilization. Fertility outcome was analyzed in 76 patients for a minimum of 6 months. INTERVENTION: Laparoscopic tubal anastomosis in 37 women and abdominal tubal anastomosis in 44. MEASUREMENTS AND MAIN RESULTS: In both groups anastomosis was performed in two layers with four stitches using microsurgical technique. Overall pregnancy rates were 80.5% in the laparoscopy and 80.0% in the laparotomy group. The mean interval from operation to pregnancy was similar in the two groups (p = 0.9). Mean operating time was significantly longer for laparoscopy (201.9 +/- 33.8 min) than for laparotomy (148.7 +/- 32.5 min), including diagnostic laparoscopy. However, mean hospital stay was shorter for laparoscopy than for laparotomy (3.3 +/- 2.0 vs 6.1 +/- 0.6 days, p <0.05). CONCLUSION: Laparoscopic tubal anastomosis is less invasive and could be an alternative to laparotomy for reversal of tubal sterilization. Advanced laparoscopic equipment and much experience could enhance the pregnancy rate and reduce operating time.     

Robotic-assisted laparoscopic microsurgical tubal anastomosis: a human pilot study

OBJECTIVE: To evaluate the feasibility and safety of a robotic device to perform a laparoscopic tubal anastomosis. DESIGN: Prospective pilot study. SETTING: Tertiary care medical center. PATIENT(s): Ten patients with previous tubal ligations underwent laparoscopic tubal ligation reversal using a robotic suturing device. INTERVENTION(s): Tubal surgery was performed with a robotic system. A two-layered closure was used for all tubes. Four stitches of 8-0 polygalactin sutures were used for each layer. MAIN OUTCOME MEASURE(s): Tubal patency; secondary measures were pregnancy rates, complications, and operative time. RESULT(s): The procedure was completed successfully in all 10 patients. No patient required conversion to an open procedure. The mean time (+/-SD) required to complete the anastomosis of both tubes was 159 +/- 33.8 minutes. Chromotubation at the end of the procedure showed patency in all tubes anastomosed. A postoperative hysterosalpingogram 6 weeks after surgery demonstrated patency in 17 of the 19 (89%) tubes anastomosed. There have been five pregnancies so far. There were no complications. CONCLUSION(s): Robotic technology can be used safely to create laparoscopic microsurgical anastomoses with adequate patency rates. Robotic technology has the potential to make laparoscopic microsuturing easier.     

Ectopic pregnancy following tubal sterilization

Over a 5 year period 232 ectopic pregnancies were recorded at Ullevaal Hospital in Oslo, Norway. There had been 10,294 births during this July 1976 to June 1981 period. In 3 cases tubal sterilization had been performed prior to the development of the extrauterine pregnancy. A total of 1047 female tubal sterilizations were performed during these 5 years. Almost all the sterilizations were done by laparoscopy. Different methods of sterilization were used: unipolar diathermy; spring clips according to Hulka; silicone rings; and endotherm coagulation. Each case of the 3 ectopic pregnancies, observed following tubal sterilization, is reviewed. A 36 year old patient became pregnant 3 years after diathermy sterilization. The right tube was found normal, and the pregnancy located in the lateral part of the divided left tube. 14 months following silicone ring sterilization a 26 year old patient had an ectopic pregnancy in the lateral right tube. The silicone ring was in perfect position on the left side. The medial right tube showed fibrous scarring after the ring application, but the ring was located in the mesosalpinx. A 37 year old patient was admitted to the hospital after a tubal pregnancy 10 months after diathermy sterilization. The pregnancy was in the lateral part of the tube. Both tubes had been transected, and there was a diastase of about 2 centimeters. The etiology of ectopic pregnancies is complex. It is only recently that previous sterilization has been recognized as a factor in this condition. Luteal phase pregnancies are because of a failure in the timing of the procedure and are unrelated to the procedure itself. Pregnancies resulting from operative failure range from 0-2.4/1000 sterilizations in different series. Technical failure may be caused by recanalization, fistula formation, and product failure. An important cause of ectopic pregnancy after laparoscopic sterilization is probably fistula formation that allows sperm to pass out of the uterus. Such fistulas have frequently been documented. Thus, if it is considered necessary to confirm tubal occlusion by salpingogram, this should be delayed for at least 12 weeks. As fistula formation probably is a major cause in this entity, division of the tube at the time of sterilization is neither necessary nor desirable. It is important to damage the tube in the isthmic segment and to minimize the involvement of the parametrium in the destructive process.     

输卵管绝育后复通手术十年总评

我们随访１９８２年４月至１９９３年６月在我院行显微输卵管复通手术后的１０２９例妇女，发现宫内妊娠率为９３．２９％（９６０／１０２９），术后第一年受孕率最高，为７３．７８％（７５４／１０２９）；术后第一年内前６个月受孕率５４．８１％（５６４／１０２９）明显高于后６个月者４０．８６％（９０／４６５）；前６个月内的前３个月受孕率３７．４１％（３８５／１０２９）又明显高于后３个月２７．８０％（１７９／６４４）。术后各时期宫外孕的发生率均无明显差别；宫内妊娠率与绝育至复通的时间无关；术后的早期通液反而降低宫内妊娠率；抽芯包埋法及夹绝育后复通的宫内妊娠率较高；输卵管峡部吻合后宫内妊娠率最高。因此，我们认为输卵管峡部的抽芯包埋法或夹绝育在目前不失为一种理想的可逆性绝育方法。     

Can open tubal microsurgery still be helpful in tubal infertility treatment?

In 30 years, 1,669 patients underwent open microsurgery for tubal diseases. Several techniques like adhesiolysis, reanastomosis, fimbrioplasty, salpingoneostomy, proximal reconstruction, isthmo-ostial anastomosis and reimplantation are described. Results were excellent for patients with a favourable prognosis (1,517 patients) and with very high pregnancy rate: 80% pregnancies with delivery for tubal reversal, 68% for proximal diseases, 75.1% for fimbrioplasty and 55% for salpingoneostomy. Risks of ectopic pregnancy were very low: 1.5% for tubal reversal (because the tubes were healthy), 4% for proximal diseases, 4% for fimbrioplasty and 6.7% for salpingoneostomy. Results were very low for patients with a poor prognosis (152 patients): 10% pregnancies with delivery for distal diseases, less than 20% for proximal diseases and 22% ectopic pregnancies. Open microsurgery can still be helpful in treating tubal infertility: results are better than those obtained with laparoscopic reconstructive surgery and better than those obtained with in vitro fertilization for patients with a favourable prognosis. Patients are only operated one time and can have several pregnancies. Open tubal microsurgery is a minimal invasive surgery and saves costs (it requires a small number of instruments and minimises sutures; patients can return home 4 days after surgery, at the latest). Results on fertility are very favourable.     

The effect of tubal ligation scoring and sterilization counseling on the request for tubal reanastomosis

Objective?The aim of this study is to emphasize the role of counseling methods that are meant to decrease the request for tubal ligation reversal, such as tubal ligation scoring.

Method?This study covers 389 patients who were admitted for tubal sterilization to Çukurova University, Faculty of Medicine, Obstetrics and Gynecology Department, between 1 January 1990 and 31 December 1999. We have used the ‘Tubal ligation score’ on these 389 patients. Four hundred and seventeen patients who underwent bilateral Pomeroy type tubal ligation during cesarean section without having undergone tubal ligation scoring in the same time interval, were accepted as the control group.

Results?Laparoscopic tubal ligation (with a Yoon ring) was performed on 368 patients who had a score of 6 or higher. Twenty-one patients who got a score of 6 or lower were recounseled and another family planning method was prescribed to them. None of the 368 patients to whom tubal ligation scoring was done previous to laparoscopic tubal ligation returned to our clinic for tubal reanastomosis. Fifteen of the 417 patients (3.6%) in the control group returned to our clinic for tubal reanastomosis.

ConclusionTubal ligation scoring may decrease the ratio of patients who request a tubal ligation reversal.     

Fertility outcome after reversal of sterilization

OBJECTIVE: The study was designed to evaluate the fertility outcome in sterilization reversals and a variety of factors that have been suggested to influence the successful outcome of sterilization reversal procedures. METHOD: It is a retrospective study involving all sterilization reversals performed between January 1991 and December 1995 in our hospital. A total of 58 cases were treated. Tubal anastomosis was performed according to rules of microsurgery. The loupe microsurgical technique with 4 x magnification comprising two main phases, preparation of healthy tubal segments and anastomosis carried out in two layers. RESULTS: It was possible to study subsequent fertility of 50 patients in all, as 8 patients were lost to follow-up (13.76%). The overall conception rate was 68% (34 cases), out of which intrauterine pregnancy rate was 62% (31 cases), ectopic pregnancy rate was 6% and the abortion rate was 6%. Fifty percent of patients conceived within first 12 months of reversal of sterilization. The isthmic-isthmic type of anastomosis has maximum incidence of pregnancies (88.88%). CONCLUSION: Laparoscopic (Falope ring) sterilization should be preferred in women who are willing for interval sterilization and it should be done at isthmic segment of the tube, whereas the Pomeroy's method is to be reserved for occasional postpartum procedure. Reversal of sterilization should be done with strict adherence to principles of microsurgery.     

Reproductive outcome in patients treated by oral methotrexate or laparoscopic salpingotomy for the management of tubal ectopic pregnancy

OBJECTIVE: To determine the reproductive outcome of women who have received methotrexate or been treated by laparoscopic salpingotomy (LS) for ectopic tubal pregnancy. STUDY DESIGN: The study consisted of 123 participants, all women with tubal pregnancies, who had been treated either by methotrexate per os or by laparoscopic salpingotomy. The reproductive outcome of these women was estimated after a follow-up time-period of ten years. RESULTS: In the methotrexate group, consisting of 34 women, the fertility rate was 82% with a mean interval time to conceive of 9.4 months after the treatment. In the group treated by LS, consisting of 89 women, the fertility rate was 82.6% and the mean interval time to conceive was 11.7 months. CONCLUSION: The reproductive outcome of the women who received either per os treatment of methotrexate or LS for tubal pregnancy, remains high. Both therapeutic methods constitute reliable solutions for managing ectopic pregnancy.

开腹与腹腔镜下输卵管吻合术回顾性队列研究及术后妊娠影响因素分析#br#

【Abstract】?Objective?To evaluate the safety and effectiveness of laparotomic and laparoscopic tubal anastomosis, and evaluate the influencing factors of pregnancy rate. Methods?The clinical data of 356 ligation patients who underwent tubal anastomosis in the First Affiliated Hospital of Zhengzhou University from March 2012 to October 2017 were analyzed retrospectively, including 85 cases of laparotomy and 271 cases of laparoscopy. The differences of perioperative status and postoperative pregnancy rate between the two groups were analyzed, and the independent influencing factors of postoperative pregnancy rate were analyzed. Results?①There was no significant difference in operation time, postoperative fever and exhaust time between the two groups (P>0.05), but laparoscopic bleeding was less[(18.1±12.1) ml, (33.4±22.1) ml], and the pain score was lower[(3.6±0.9), (4.5±0.9) score], duration of hospital stay was shorter[(5.9±0.6) d, (7.1±0.7) d](P<0.05). 2 cases of laparotomic group had abdominal wall incision infection, cases of laparoscopic group all healed well. The cost of laparotomic group was lower than that in laparoscopic group[(9 524±881), (12 903±1 162) yuan](P<0.05).② There was no significant difference in the patency rate of intraoperative anastomosis, residual tube length and ectopic pregnancy rate between the two groups (P>0.05). The uterine pregnancy rate two years after anastomosis was higher in laparoscopic group (76.4%) than in laparotomic group(61.2%)(P<0.05). The postoperative gestation time of the laparoscopic group was (7.6±4.9) months, and the postoperative gestation time of the open group was (8.3±5.3) months, with no statistically significant difference(P>0.05).③ Anastomotic procedure (OR=1.847, 95%CI: 1.028~3.320, P=0.040), age (OR=3.673, 95%CI: 1.690~7.984, P=0.001), multiple pelvic operation history (OR=3.092, 95%CI: 1.650~5.796, P=0.000), and length of residual tube (OR=4.716, 95%CI: 2.552~8.714, P=0.000) were independent factors influencing intrauterine pregnancy rate after anastomosis. There was no significant correlation between body mass index (BMI), length of ligation, method of ligation and site of ligation and pregnancy rate. Conclusion?Compared with open surgery, laparoscopic tubal anastomosis is a better treatment option for patients with tubal ligation. Anastomosis mode, age, history of multiple pelvic surgeries and length of remaining fallopian tubes were the influencing factors of pregnancy rate after anastomosis.     

Fertility outcomes subsequent to treatment of tubal ectopic pregnancy in younger Turkish women

Study Objective

The assessment of future fertility in patients that were hospitalized with diagnosis of tubal ectopic pregnancy.

Design

Between January 1998 and September 2008, we retrospectively reviewed 219 tubal ectopic pregnancy patients who were hospitalized. The patients using contraceptive methods, underwent previous pelvic or tubal surgery, pregnancy after in vitro fertilization, over the age of 28, and extratubal ectopic pregnancies were excluded. Patients who actively attempted to conceive were included. We called all the patients to see whether they had pregnancy in 24 months, and how long they had waited for this after the operation. Overall, we could not reach 14 patients who were treated surgically (n = 9) or medically (n = 5).

Setting

Department of Obstetrics and Gynecology, Ege University, Izmir, Turkey.

Participants

Women aged between 18 and 28 years that were treated because of tubal ectopic pregnancy and have concerns about infertility.

Interventions

Medical treatment with methotrexate (n = 34), salpingectomy (n = 62) salpingostomy (n = 37).

Main Outcome Measures

Intrauterine pregnancy rates, ectopic pregnancy rates and mean time to pregnancy after interventions.

Results

After questionnaire: in the methotrexate group; six of 29 (20%) had no pregnancy; 23 (79%) of them conceived, but three (10%) of the pregnancies were extrauterine. Thirty-seven patients received salpingostomy and 62 patients composed the salpingectomy group. Intrauterine pregnancy rates up to 24 months were established as 65.2% in salpingectomy (n = 55) and 60.1% in the salpingostomy (n = 35) groups respectively. No significant difference was noticed when pregnancy rates were compared among three groups (P = 0.942). Mean time to pregnancy in methotrexate group was 7.8 ± 2.2 months, and in salpingostomy and salpingectomy groups was 8.7 ± 2.2 and 9.3 ± 3.1 months respectively (P = 0.841).

Conclusion

Since we found no difference in terms of pregnancy rates among three groups, medical treatment appears to be more favored with early and accurate diagnosis. After salpingectomy, patients may conceive later in life when compared with other groups so selected patients should be assessed according to their age for the decision of assisted reproductive techniques.     

Surgical management of cornual-isthmic tubal obstruction

Objective: To examine the efficacy of microsurgical tubal anastomosis among patients having failed attempts to correct cornual-isthmic tubal obstruction by hysteroscopic tubal catheterization.Design: An open observational trial.Setting: A tertiary referral reproductive medicine practice.Patient(s): Forty-three patients with laparoscopically confirmed bilateral cornual-isthmic obstruction and otherwise normal fallopian tubes. Thirty-three control patients with a history of elective sterilization presenting for tubal anastomosis.Intervention(s): All patients with bilateral cornual-isthmic obstruction underwent attempted hysteroscopic tubal cannulation. Those unsuccessfully catheterized proceeded with microsurgical resection and anastomosis. Candidates for reversal of sterilization underwent microsurgical repair in standard layered technique.Main Outcome Measure(s): Mean time to achieve pregnancy, as well as cumulative pregnancy rates for all three groups using life-table analysis, were calculated.Result(s): Cumulative pregnancy rates for patients with successful tubal catheterization, for those requiring microsurgical repair, and for reversal of elective sterilization were 0.68%, 0.56%, and 0.29%, respectively, at 12 months. Mean duration to achieve pregnancy was similar for both cornual-isthmic blockage-treated groups and was shorter than that for the sterilization-reversal group.Conclusion(s): Patients with cornual-isthmic obstruction and otherwise normal fallopian tubes who are treated successfully by either tubal catheterization or resection and microsurgical anastomosis demonstrate high pregnancy rates, short interval to achieve pregnancy, and similar obstetric outcome. If no pregnancy is achieved within 1 year of surgery, reevaluation and consideration for possible IVF and ET is indicated.     

Tubal anastomosis for reversal of sterilization with microsurgical technic in 246 women

Tubal anastomosis for reversal of sterilization was performed with microsurgical technique in 246 women, from January 1985 to June 1987. The operation time after tubal sterilization averaged 43.5 months. The patients (99.6%) were followed-up for 3-33 months. Intrauterine pregnancies occurred in 178 cases, the rate being 72.4%. The factors which influence success rate are the tubal length after anastomosis and the mode of original tubal ligation. Postoperative instillation of fluids into fallopian tubes should be performed early to prevent adhesions and early intercourse should also be encouraged.
