Implantation of the zygote outside the uterine cavity occurs in 2% of all pregnancies. The product of conception can be removed safely by laparoscopic surgery and be submitted for histological examination. The rate of ectopic pregnancies has increased from 0.5% in 1970 to 2% today. The prevalence of ectopic pregnancy in all women presenting to an emergency department with first-trimester bleeding, lower abdominal pain, or a combination of the 2 is between 6% and 16%. DESIGNATION: Workup of all localizations of ectopic pregnancies at a university department of obstetrics and gynecology. Comparison of diagnostic and therapeutic modalities from the surgical laparoscopic approach to nonsurgical, medical options. Tubal pregnancies: (1) to preserve tubal function, salpingotomy, partial salpingectomy followed by laparoscopic anastomosis, or fimbrial milking is performed. (2) Tubectomy or salpingectomy is performed only in severely damaged or ruptured tubes or if the patient does not desire further pregnancies. Nontubal ectopic pregnancies (ovarian pregnancy, ectopic abdominal pregnancy, interstitial or cornual pregnancy/rudimentary horn, intraligamental and cervical pregnancies) all require their own specific treatment. The predominant drug is methotrexate, but other systemic drugs, such as actinomycin D, prostaglandins, and RU 486, can also be applied. Tubal rupture is a complication of late diagnosed tubal pregnancy that is more difficult to treat conservatively and often indicates tubectomy or segmental resection. In 5% to 15% of treated ectopic pregnancy cases, remnant conception product parts may require a final methotrexate injection. This article is a review to aid clinical diagnosis of ectopic pregnancies that now can be diagnosed earlier and treated effectively by laparoscopic surgery.

Genital prolapse is frequent in postmenopausal women; it describes the loss of support to the pelvic organs, resulting in a herniation of these into the vaginal channel. This problem affects 50% of parous women, and at least 50% of all women develop a mild form of genital prolapse after pregnancy. An extensive literature review from 1990 to 2008 was performed on prolapse etiology and its risk factors; analyzing the data, we reviewed the genetic and biological aspects, age-related prolapse, biological tissue modifications, surgical problems, pelvic musculature modifications, and neuropathy. Data suggested that aging, pelvic trauma, and surgery evoke tissue denervation and devascularization, anatomic alterations, and increased degradation of collagen; all of these may lead to a decrease in mechanical strength and predispose an individual to prolapse. It has been demonstrated that there is a reduction in protein content and estrogens in uterosacral ligaments, in the vagina, and in the parametrium of women with prolapse. This is a possible explanation for why many surgical procedures to correct prolapse fail and recurrences after surgical correction are frequent. Even if the etiology of pelvic prolapse is poorly defined and multifactorial, aging risk factors, such as biomechanical abnormalities in connective tissue composition, hormonal deficiency, and irregular tissue metabolism, are nonmodifiable and therefore largely stated in clinical practice. Regardless of future developments, based on the reported findings, prolapse therapy will be more influenced by genetics, biological pelvic changes, changes in tissue homeostasis, and topical hormones, rather than general pelvic corrective surgical anatomy.

Myomas are the most common benign tumors of the genital organs in women of childbearing age, causing significant morbidity and impairing their quality of life. In our investigation, we have reviewed the epidemiological data related to the development of myomas in order to homogenize the current data. Therefore, a MEDLINE and PubMed search, for the years 1990-2013, was conducted using a combination of keywords, such as "myoma," "leiomyoma," "fibroids," "myomectomy," "lifestyle," "cigarette," "alcohol," "vitamins," "diet," and "hysterectomy". Randomized controlled studies were selected based upon the authors’ estimation. Peer-reviewed articles examining myomas were sorted by their relevance and included in this research. Additional articles were also identified from the references of the retrieved papers and included according to authors’ estimation.

Our aim was to assess surgical complaints and reproductive outcomes of laparoscopic intracapsular myomectomies by a prospective observational study run in University affiliated hospitals. Between 2005 and 2010, 235 women underwent subserous and intramural laparoscopic myomectomy of fibroids (4–10 cm in diameter) for indications of pelvic pain, menstrual disorders, a large growing myoma or infertility. The main outcome measures were post-surgical parameters, including complications, the need for subsequent surgery or symptomatic relief, resumption of normal life and reproductive outcome. Pelvic pain occurred in 27%, menorrhagia or metorrhagia in 21%, a large growing myoma in 10% and infertility in 42% of women. Single fibroids occurred in 51.9% of patients while 48.1% had multiple myomas. Of all patients, 58.2% had subserosal and 41.8% had intramural myomas. No laparoscopies were converted to laparotomy. In 3 years, 1.2% of patients had a second laparoscopic myomectomy for recurrent fibroids. The mean total operative laparoscopic time was 84 min (range 25–126 min), with mean blood loss of 118 ± 27.9 ml. By 48 h after surgery, 86.3% were discharged with no major post-operative complications. No late complications, such as bleeding, urinary tract infections or bowel lesions, occurred. Of the women who underwent myomectomy for infertility, 74% finally conceived. At term, 32.9% of patients underwent Caesarean section, 24.8% delivered by vacuum extractor and 42.2% had spontaneous deliveries. No case of uterine rupture occurred. Intracapsular subserous and intramural myomectomy saving the fibroid pseudocapsule showed few early and no late surgical complications, enhanced healing by preserving myometrial integrity and allowed a good fertility rate and delivery outcome. In young patients suffering fibroids, laparoscopic intracapsular myomectomy is a potential recommended surgical treatment.

A critical analysis of the surgical treatment of fibroids compares all available techniques of myomectomy. Different statistical analyses reveal the advantages of the laparoscopic and hysteroscopic approach. Complications can arise from the location of the fibroids. They range from intermittent bleedings to continuous bleedings over several weeks, from single pain episodes to severe pain, from dysuria and constipation to chronic bladder and bowel spasms. Very seldom does peritonitis occur. Infertility may result from continuous metro and menorrhagia. The difficulty of the laparoscopic and hysteroscopic myomectomy lies in achieving satisfactory haemostasis using the appropriate sutures. The hysteroscopic myomectomy requires an operative hysteroscope and a well-experienced gynaecologic surgeon.
