Risk factors for conversion to laparotomy during laparoscopic management of an ectopic pregnancy.

OBJECTIVE: To identify risk factors for conversion to laparotomy during laparoscopic management of ectopic pregnancy. METHODS: A retrospective chart review of patients who underwent laparoscopy for treatment of ectopic pregnancy, during a 32-month period (6/1999-2/2002), at the University of Miami Jackson Memorial Hospital. We identified 229 patients; 201 had a successful laparoscopy (non-converted group) and 28 who were converted to laparotomy (converted group). Variables analyzed between the two groups were demographic data, patient-related risk factors available to the surgeon prior to the surgery (previous laparotomy, previous laparoscopy, history of PID, history of endometriosis, diameter of ectopic pregnancy as measured by ultrasound, amount of free fluid on ultrasound, BMI), and surgeons' experience. RESULTS: Out of the 229 laparoscopies, 28 were converted to laparotomy (12.2%). The rate of conversion was significantly higher for less experienced compared to experienced surgeon (OR = 6.1, 95% CI = 2.35-15.88). Significantly more women had a BMI > 30 kg/m2 in the converted group compared to the non-converted group (42% vs. 14%; OR = 4.28, 95% CI = 1.7-10.75) and the converted group had significantly higher rate of large free fluid reported on ultrasound compared to the non-converted group (21.42% vs. 7.46%; OR = 3.38, 95% CI = 1.04-10.61). CONCLUSION: Less experienced surgeon, BMI > 30 kg/m2, and large amount of free fluid on ultrasound increase the risk of conversion to laparotomy during laparoscopic management of ectopic pregnancy.

Ectopic pregnancy.

Ectopic pregnancy is a implantation occurring elsewhere than in the cavity of the uterus, whereas ninety-nine percent of extrauterine pregnancies occur in the fallopian tube. The incidence of extrauterine pregnancy has increased from 0.5% thirty years ago, to a present day 1-2%. The most frequent cause of tubal pregnancy is previous salpingitis. Mortality rates for tubal pregnancies used to be approximately 1.7% in the 1970s but dropped to 0.3% in 1980s. DIAGNOSIS: Using transvaginal ultrasound it is possible to obtain positive evidence of an ectopic pregnancy at a very early stage. In cases of hCG titers>2,000 IU/l, intrauterine pregnancy can be diagnosed with certainty. The most important differential diagnosis of ectopic pregnancy is early intrauterine pregnancy. CLINICAL MANAGEMENT AND THERAPY: Regardless of the therapeutic strategy selected by the physician, informing the patient is a major aspect of the management of ectopic pregnancy. If surgery is considered appropriate, the patient must be informed about the nature, side effects and complications of the procedure. However, it should be remembered that in some cases, the actual chances of cure first become apparent at surgery. In asymptomatic patients with a serum hCG titer <1,000 IU/l that is falling, it is appropriate to wait and watch. In clinically stable patients with an unruptured tubal pregnancy and steady hCG levels, systemic treatment with methotrexate might also be considered. In unruptured tubal pregnancy with a hCG titer between 1,000 and 2,500, a further therapeutic alternative is intratubal injection of prostaglandins, hyperosmolar glucose of NaCl. Generally speaking, the currently widespread laparoscopic surgical treatment of the fallopian tube hardly influences the risk of recurrence. If the gestational mass is larger, the serum hCG titer higher than the approximate limit of 2,500 mU/ml and/or the tube already ruptured, surgery is usually required. PREVENTION: The most effective prevention is to avoid tubal inflammation or, in cases of preexisting inflammation, to administer effective therapy.

Somatostatin receptor scintigraphy: its value in tumor localization in patients with Cushing's syndrome caused by ectopic corticotropin or corticotropin-releasing hormone secretion.

PURPOSE: To assess the feasibility of somatostatin receptor scintigraphy for patients with Cushing's syndrome caused by tumors secreting ectopic corticotropin or corticotropin-releasing hormone (CRH). PATIENTS AND METHODS: Ten patients with Cushing's syndrome, nine with ectopic corticotropin-secreting tumors and one with a CRH-secreting tumor, were consecutively studied. For comparison purposes, eight patients with corticotropin-secreting pituitary tumors and one patient with an autonomous adrenal adenoma were investigated. In vivo tumor localization was performed for all patients using a radionuclide-coupled somatostatin analog. The results obtained with this technique were compared with those obtained with conventional imaging techniques. For some patients, the clinical effects of octreotide therapy were evaluated. RESULTS: Somatostatin analog scintigraphy successfully identified the primary ectopic corticotropin-secreting and CRH-secreting tumors or their metastases, or both, in 8 of 10 patients; in 2 patients with corticotropin-secreting bronchial carcinoids, the tumors could not be visualized. Normal scans were obtained for the 8 patients with corticotropin-secreting pituitary tumors and the one patient with an adrenal adenoma. CONCLUSION: Somatostatin analog scintigraphy can be included as a diagnostic step in the workup of Cushing's syndrome patients with a suspected ectopic corticotropin-secreting tumor or a CRH-secreting tumor.

Rh immunoglobulin utilization after ectopic pregnancy.

To assess the use of Rh immunoglobulin (RhIG) after ectopic pregnancy, we reviewed the charts of 305 patients treated from 1975 through 1978 at a large metropolitan hospital. We compared these patients with 389 who had had spontaneous abortions and been treated at the same hospital in 1975. The rate of ascertainment of Rh type was significantly higher for the group with ectopic pregnancy than for the group with spontaneous abortion (98.4% versus 95.1%; p less than 0.05). Nevertheless, presumable fertile RhIG candidates after ectopic pregnancy were 3.3 times more likely not to receive RhIG than candidates after spontaneous abortion (64.3% versus 19.4%;; p less than 0.01). Patients with ectopic pregnancy are an important part of the "RhIG utilization gap"; the mechanism for providing prophylaxis for patients needs to be improved.

Vaginal douching as a potential risk factor for tubal ectopic pregnancy.

The incidence of ectopic pregnancy in the United States has more than doubled in the past decade. Because a previous study has suggested that the practice of vaginal douching may increase the risk of pelvic inflammatory disease, a condition known to predispose to ectopic pregnancy, and because the sale of commercial douching products in the United States has more than tripled since 1974, we investigated this practice as a possible risk factor. We interviewed 155 women who had a tubal ectopic pregnancy treated at five Seattle hospitals between 1975 and 1979 as to their reproductive, contraceptive, and medical histories, demographic characteristics, and personal hygiene practices. During the same period, 456 women who were delivered of a baby in King County were identified from Vital Records and interviewed as controls. A higher proportion of cases than controls reported ever having douched in the past. Cases also douched more frequently than controls. After simultaneous adjusting for confounding factors in our data by means of a multiple logistic regression technique, the risk of tubal ectopic pregnancy for women who douched at least weekly was twice that of women who never douched (95% confidence interval = 1.03 to 4.00). The risk for women who used commercial douches on a weekly basis was 4.4 (95% confidence interval = 1.6 to 12.7) the risk for women who never douched.

Tubal conservation in ectopic pregnancy: a study of 200 cases.

There have been 1152 cases of ectopic pregnancy at Kaiser Permanente Hospital from 1953 to 1980. In 200 cases the involved tube was preserved with no surgical complications. There have been 122 subsequent pregnancies, 24 of which were repeat ectopic pregnancies. Twelve were in the involved tube and 12 were in the opposite tube, demonstrating conclusively that both tubes are at equal risk of ectopic pregnancy. Conserving the involved tube does not increase the incidence of ectopic pregnancy but does increase the chances for intrauterine pregnancy in this subfertile population.

Ectopic tubal pregnancy treated by operative laparoscopy.

Between July 1986 and May 1988, all 23 patients with ectopic tubal pregnancies of 5 to 10 1/2 weeks' gestation and with serum beta-human chorionic gonadotropin levels between 51 and 92,610 mIU/ml (first international reference preparation) were treated by operative laparoscopy. Twenty-two (96%) of the ectopic pregnancies were unruptured or leaking and one (4%) was ruptured. Fifteen patients (65%) were treated with electrosurgical linear salpingotomy, and three of these patients (20%) later needed subsequent operative procedures. Six patients (26%) were treated with laparoscopic partial or total salpingectomy, and two patients were treated with either fimbrial expression of the pregnancy or completion of a partial abortion. Twenty patients (87%) spent less than 24 hours in the hospital for successful treatment of the ectopic pregnancy. It is concluded that operative laparoscopy should be considered an alternative to laparotomy or minilaparotomy for the treatment of ectopic pregnancy.

Reproductive performance after methotrexate treatment of ectopic pregnancy.

The purpose of this study was to examine return of reproductive potential, hysterosalpingographic findings, and time to conception in patients treated with methotrexate and citrovorum factor for unruptured ectopic pregnancy. Fifty-seven patients with unruptured ectopic pregnancies less than 3.0 cm in greatest dimension were treated with methotrexate and citrovorum factor. The mean time from resolution of the ectopic pregnancy to return of menses was 26.0 (0 to 157) days. Forty-four patients were available for follow-up (2 to 15 months). Nineteen of 23 patients who had hysterosalpingograms demonstrated patency in the ipsilateral tube. Fourteen patients desired pregnancy; 11 of 14 (78.6%) were successful, with 10 of 11 (90.9%) having an intrauterine pregnancy, whereas one of 14 (9.1%) were extrauterine gestations. The mean time from first attempt to achieving pregnancy was 2.3 (1 to 4) months. We conclude that methotrexate and citrovorum factor treatment of unruptured ectopic pregnancy is associated with subsequent tubal patency and does not impair return of menses. Most importantly, the pregnancy rates after this form of therapy appear to be better than those achieved by traditional surgical methods, and are comparable to results after laparoscopic salpingostomy.

Human chorionic gonadotropin in the ectopic gestation.

The ectopic pregnancy is a relatively common condition in the south African black patients. The beta-specific subunit radioimmunoassay for human chorionic gonadotrophin (HCG) was utilized in procuring information in our series of 30 patients. Levels of the hormone were significantly lower when compared to normal gestation of similar duration, never exceeding 2000 mIU/ml. The clearance rate of HCG following normal vaginal delivery was about 24 h and less variable than that of ectopic gestation. The half-life clearance rate of HCG in the ectopics could be divided into three phases, suggestive of HCG compartmentalization. The possible buffering effect of this hormone in the maintenance of the receptor-saturated pregnancy is discussed. The possibility that the HCG produced by the normal pregnancy is dissimilar to that of ectopic is speculated upon.

Bilateral ectopic gestations.

Bilateral ectopic gestations are a rare form of double ovum pregnancy. The following case report of a patient with a ruptured ectopic gestation of the left fallopian tube and an unruptured ectopic gestation of the right fallopian tube is presented to demonstrate the importance of thoroughly examining the entire pelvis at the time of exploratory laparotomy undertaken for suspicion of ectopic pregnancy.

Ectopic pregnancy and chlamydial serology.

OBJECTIVES: To determine the prevalence of humoral IgG antibodies to Chlamydia trachomatis in women with tubal pregnancies. METHODS: A study was made of 49 women with tubal pregnancies. The control group consisted of 50 pregnant women without any known fertility problems. RESULTS: Compared with the pregnant group of women, a statistically significant higher prevalence of chlamydial IgG antibody titer > or = 64 was observed among the patients with gross abnormalities in the fallopian tube contralateral to the ectopic gestation (P = 0.002). The differences in geometric mean titer (GMT) were also statistically significant (P = 0.0004) between those two groups. The recall frequency of past pelvic inflammatory disease (PID) was increased 5-6-fold in patients with ectopic pregnancy, compared with the intrauterine pregnant women. Twenty-five of 30 patients (83%) with ectopic pregnancy and macroscopic tubal sequelae recalled a history of PID. The prevalence of chlamydial IgG antibody titer > or = 64 among women with a past history of PID was 75.6% (34/45), compared with 44.4% (24/54) among the women without any history of past PID history (P = 0.002). Concerning GMT, the numbers were 27 and 154 among women with and without a past history of PID, respectively (Fig. 2). CONCLUSIONS: These findings suggest that C. trachomatis is a major cause of oviductal damage, which predisposes to ectopic pregnancy.

Diagnosis of intrauterine and ectopic pregnancy at 5-7 postmenstrual weeks.

OBJECTIVES: The potential of the combined use of vaginosonography and serum beta-hCG levels for early diagnosis of intrauterine and ectopic pregnancies (5-7 weeks postmenstrual) was investigated in a multicentric study. METHODS: Three hundred and forty-nine patients underwent vaginosonographic examination and determination of serum beta-hCG. When the first examination failed in establishing a precise diagnosis, repeat examinations were performed on alternate days. RESULTS: During the first 3 weeks after the missed menses, vaginosonography can detect practically all viable intrauterine pregnancies, half of the nonviable intrauterine and viable ectopic pregnancies, and one quarter of nonviable ectopic pregnancies, respectively. It was not possible to differentiate intrauterine and ectopic pregnancies by serum beta-hCG levels. CONCLUSIONS: Vaginosonographic screening, ideally at 2 weeks after the missed menses, permits detection, localization, and dating in 80%-90% of suspected pregnancies.

Diagnosing unruptured ectopic pregnancy.

OBJECTIVE: A retrospective analysis of the management of ectopic pregnancy at Korle Bu Teaching Hospital in Accra, Ghana, to assess the impact of the introduction of ultrasonography as a diagnostic tool. METHODS: All charts of patients with ectopic pregnancies from 1 January 1986 to 31 December 1990 were analyzed. The management of those patients who had transabdominal ultrasonography was compared with those who had not. RESULTS: The use of ultrasonography increased the number of unruptured ectopic pregnancies from 0.3% to 8.5% (P < 0.001). This also reflected a reduction in misdiagnoses, blood transfusions, and maternal deaths. CONCLUSIONS: The reasonable use of modern technology can be of great assistance even in developing countries, as shown by the positive impact of the use of ultrasonography to aid in the diagnosis of ectopic pregnancy in Ghana, West Africa.

Previous cesarean delivery and the risk of ectopic pregnancy.

OBJECTIVE: To determine whether previous cesarean delivery is an independent risk factor for ectopic pregnancy. METHODS: We analyzed data collected between October 1988 and August 1990 from a case-control study of ectopic pregnancy among parous, black, non-Hispanic women, 18-44 years old, at a major metropolitan hospital in Georgia. Cases were 138 women with confirmed ectopic pregnancy; controls were 842 women either seeking abortion or delivering an infant. Unconditional logistic regression was used to estimate the relative risk while controlling for the effects of potential confounders selected a priori. RESULTS: Adjusted for age, parity, marital status, history of pelvic inflammatory disease, infertility, douching, and smoking, the odds ratio was 0.6 (95% confidence interval 0.4-1.1), indicating no significant association. CONCLUSION: We found no evidence of an increased risk of ectopic pregnancy related to previous cesarean delivery.

Low-dose oral methotrexate with expectant management of ectopic pregnancy.

OBJECTIVE: To investigate recovery times and need for laparoscopy in women with ectopic pregnancy who were treated for 5 days 2.5 mg/day of oral methotrexate or placebo. METHODS: Sixty women with ectopic pregnancy among patients of an outpatient clinic specializing in early pregnancy disorders were selected for medical treatment in a double-blind, placebo-controlled study. The diagnosis was made by transvaginal sonography and serum hCG determinations, either at admission or after repeated examinations. Women were recruited for the study if they had mild symptoms: the hCG increase was less than 50% within 2 days, the diameter of the ectopic pregnancy was less than 40 mm, there were no signs of intra-abdominal bleeding by transvaginal sonography, and there were no secondary reasons for laparoscopy. Either 2.5 mg of methotrexate or placebo was given orally for 5 days. Serum hCG was determined after 2 days, and hCG, red blood cell count, white blood cell count, platelet count, and serum glutamic-oxaloacetic transaminase were measured; transvaginal sonography was performed after 5 and 12 days. Expectant management was continued individually with check-ups at 1-3-week intervals. Laparoscopy was performed if the patient developed abdominal pain or intra-abdominal hemorrhage, as seen by transvaginal sonography. Statistical analysis was by paired or unpaired t test, Mann-Whitney U test, regression analysis, and repeated measures analysis of variance. RESULTS: Seventy-seven percent of the patients recovered without the need for laparoscopy in both groups, and there were no significant differences in recovery times or the need for laparoscopy between groups. CONCLUSION: Oral methotrexate, 2.5 mg for 5 days, does not appear to be more effective than placebo in the treatment of ectopic pregnancy in women eligible for expectant management.

Ectopic pregnancy and laparoscopy: review of 1197 patients treated by salpingectomy or salpingotomy.

The past few decades have witnessed such a rapid rise in the incidence of ectopic pregnancy that it verges on the point of an 'epidemic disease'. Its early detection, with the aid of serum beta-hCG, high resolution ultrasound and the more liberal use of laparoscopy, has dramatically altered the clinical presentation of this disease and permits the use of more conservative methods of management directed towards preserving fertility and reducing morbidity. In this review of 1197 patients, compiled from the English literature, various conservative or tubectomy operative laparoscopic procedures have been employed, with 93% and 98% respectively, being able to avoid further surgery. Among the group treated by the conservative approach, a 6% post-operative complication rate was reported, of which 4% were persistent ectopic, 48% intra-uterine, and 18% repeated ectopic pregnancies. Among the radically treated patients, 2 intra- and 1 post-operative complications necessitated laparotomies. The fertility work-up and performance outcome are less obvious among this group. The benefits, safety and efficacy of each of the laparoscopic options, with appropriate recommendations for their use, are discussed. However, despite the aforementioned dramatic progress, women with previous ectopic pregnancies still have reduced fertility potential. Preventive measures aimed at reducing its overall occurrence therefore seem to be the major factor towards preserving a patient's future fertility potential.

Resorption of maxillary lateral incisors caused by ectopic eruption of the canines. A clinical and radiographic analysis of predisposing factors.

Factors predisposing to resorption of adjacent permanent lateral incisors caused by ectopic eruption of maxillary canines were evaluated. The subjects consisted of two groups: one with 40 lateral incisors with resorption caused by ectopic eruption and a control group of 118 ectopic eruption cases with no lateral incisor resorption. The mean age of the children in the two groups differed by only 0.7 of a year and ranged from 10.0 to 15.0 years, covering the normal eruption period of the maxillary canine. Resorption of lateral incisors was three times as common in girls as in boys. The resorption cases showed a more advanced dental development, a more medial canine position in the dental arch, and a slightly more mesial horizontal path of eruption (an average of 10 degrees) than that of the control cases. Factors such as the width of the dental follicle and proclination or distal tilting of the lateral incisor showed no correlation to the resorption. Potential resorption cases are always those in which the canine cusp in periapical and panoramic films is positioned medially to the midline of the lateral incisor. Such situations should be carefully investigated with polytomography if necessary. The risk of resorption also will increase with a more mesial horizontal path of eruption. From 10 years of age or younger, annual clinical examination by palpation of the canine eruption path is recommended. This clinical examination should be supplemented with a stepwise extended radiographic procedure in cases in which ectopic eruption of the maxillary canines is suspected.

Diagnosis and surgical treatment of ectopic atrial tachycardia.

Eighty-two patients with ectopic atrial tachycardia (EAT) were subjected to radical closed heart surgery (without cardiopulmonary bypass). The age of the patients ranged from 1 to 51 years. Permanent EAT was present in 19 patients, incessant EAT in 14, and paroxysmal EAT in 49 patients. Preoperative electrophysiological study included computed analysis of the P wave vector. Ectopic foci were established in the right atrium in 34 patients, in the left atrium in 11, in the interatrial septum in 32, and extracardially in 5 patients. For ablation or isolation of the foci, the cryogenic technique was used in 74 patients, cryo- and laser techniques in 4, and the laser technique alone in 1 patient. In 3 patients resection of the atrial auricles including the ectopic focus was undertaken. In 4 patients complete AV block was induced and a cardiac pacemaker implanted. After primary surgery, favourable results were obtained in 71 patients. In 11 patients recurrences were observed; 8 of these patients underwent successful repeat surgery. In 3 patients medical treatment was effective. Finally, the follow-up results have been promising-79 patients (96.4%) (including 4 patients in whom a complete AV block was created) have become arrhythmia-free. When EAT is resistant to medical treatment, closed heart ablation of the ectopic focus has proved to be safe (no mortality or morbidity) and effective. It can therefore be recommended not only for the termination of EAT but also for the prevention of dilated cardiomyopathy.
