Small bowel involvement by endometriosis occurs in about 0.5% of patients, but nodular endometriosis involving the entire wall of the terminal ileum is extremely rare. Endometriotic nodules protruding into the intestinal lumen may lead to chronic, partial, or acute complete small bowel obstruction and associated clinical changes. If obstruction is partial, preoperative diagnosis is difficult and seldom suspected, and no reliable diagnostic tests are available. At laparoscopic surgery, performed typically for associated pelvic endometriosis, bowel lesions may easily be overlooked, especially in women with abdominal adhesions from earlier surgery. Surgical injury, tension tears, or postoperative edema may contribute in such cases to the development of acute, complete small bowel obstruction, which may be difficult to differentiate from postoperative ileus. The patient may deteriorate rapidly and develop abdominal sepsis and multiple organ failure with high risk of mortality. Because of increased production of tumor necrosis factor-alpha by autologous monocytes, endometriosis may predispose to development of severe sepsis and septic shock.

To evaluate the reliability of diagnosing minimal and mild endometriosis under routine conditions, and to determine to what extent disease activity is taken into account. Retrospective analysis (Canadian Task Force classification II-2). University teaching hospital. Laparoscopy. One hundred eighteen consecutive women with minimal and mild endometriosis undergoing routine surgery between 1994 and 1999. MAIN Analytic parameters were the total number of endometriotic lesions; intraoperative description of pigmented, nonpigmented, and nondefined lesions; and number of extirpated lesions and histologic detection rate. In 118 patients, 311 suspected endometriotic lesions were documented. Nonpigmented lesions were reported in only 27% of women. In 51% of surgical reports no importance was attached to disease morphology or activity. Only 1.2 biopsies/patient were taken. The histologic detection rate was 56%. In 49 patients the assumed intraoperative diagnosis was confirmed by histologic examination. Intraoperative description of endometriotic lesions is inadequate. Little attention is paid to the activity of the illness. There is room for improvement in the number of excisions and histologic detection, and an attempt should be made to find a way out of this diagnostic dilemma.

To determine whether routine clinical examination is sufficient for the diagnosis and establishing the location of deeply infiltrating endometriosis (DIE). Retrospective analysis (Canadian Task Force classification II-2). University-affiliated hospital. Patients. One hundred sixty women with histologically proved deeply infiltrating endometriosis. MAIN Speculum examination allowed endometriotic lesions to be viewed in only 14.4% (23) of patients, and a classic, painful, spheric nodule was palpated in only 43.1% (69). Results of routine clinical examination varied significantly with location of DIE. Whereas a nodule was found in 80.0% (24) of patients with vaginal endometriosis, this rate dropped to only 35.3% (6) and 33.3% (34) in those with DIE of the digestive tract and uterosacral ligaments, respectively (p <0.0001). High locations of DIE lesions at the level of uterosacral ligaments, bottom of the pouch of Douglas, and upper one-third of the posterior vaginal wall explain why results of routine clinical examination are so poor. The term "deep endometriosis infiltrating the rectovaginal septum" is generally incorrect in the true anatomic sense.

To determine the prevalence of reproductive pathology in a group of infertile women thought to be at low risk for altered pelvic anatomy. Retrospective chart review and follow-up (Canadian Task Force classification II-2). Academic-affiliated, private reproductive endocrinology practice. One hundred infertile women. Diagnostic and/or therapeutic laparoscopy. MAIN Of 100 patients with a negative reproductive work-up up to the point of laparoscopy, 68 intrinsic tubal disease 24, peritubal adhesive disease 34, and endometriosis 43, some in combination. Laparoscopy was especially helpful in establishing treatment protocols for older women, who were referred for assisted reproductive techniques earlier than otherwise might have been the case. Women conceived after hormone therapy and after operative intervention. Although the hysterosalpingogram was read as normal in all women, tubal disease was diagnosed laparoscopically, independent of endometriosis, in 27 patients, with 2 having complete obstruction. Endometriosis stage I-II was found in 22 patients, stage III in 13, and stage IV in 6. Even in women thought to be at low risk for significant pelvic pathology affecting reproduction, the yield was high. Although some pregnancies were achieved after operative intervention, frequently laparoscopy was helpful in making a decision to go to assisted reproductive technology, particularly when infertility had been of long duration and in older women. Frequently the degree of pathology was such that a full operating suite was necessary to provide adequate instrumentation and anesthesia for operative intervention, which would not have been the case with office laparoscopy.

Ten women had endometriosis and pelvic peritoneal defects of the posterior leaf of the broad ligament, with the consistent finding of medial displacement of the ureter toward the uterosacral ligament. Ureterolysis at the time of surgery revealed the underlying course of the ureter and its proximity to the uterosacral ligament, making it susceptible to surgical injury. It is important for surgeons to be aware of this anatomic alteration associated with these specific peritoneal defects.
