Two women with a ventriculoperitoneal shunt had primary infertility. At laparoscopy they both had extensive peritoneal adhesions that made evaluation of pelvic organs impossible and increased the risk of bowel injury. History of ventriculoperitoneal shunt should be considered a contraindication of laparoscopy.
The analysis of records of amoebal infection in various hospitals in Kilimanjaro indicated frequent occurrence of amebiasis. The population over the age of five years had higher rate of amoebal infection compared to less than that of a five-year-old population; however, both age groups had similar patterns of amebiasis during January 1999 to June 2001. To investigate misdiagnosis of amebiasis, 226 patients (passive cases) in three hospitals and 616 individuals (active cases) from three different localities in Kilimanjaro were examined. In passive cases, the prevalences of Entamoeba histolytica and Entamoeba dispar were 1% and 7.3%, respectively. Among active cases, 1% were infected with E. histolytica, and 15% were infected with E. dispar. There were no significant differences in amoebal infection between the male and female populations. A pool of 842 stool samples was used for diagnosis of E. histolytica and E. dispar by microscopic examination or ELISA kits. The microscopic examination indicated 8.7% amoebal infection; however, using ELISA as the gold standard, the prevalence of histolytica/dispar was 0.8% and 7.4%, respectively. This study indicated that E. dispar infection was 14.5 times more prevalent than E. histolytica infection.

We performed an innovative technique of temporary ovarian suspension after operative laparoscopy for stage 3 and 4 endometriosis and evaluated the results in a retrospective study. Subjects were 20 women who underwent operative laparoscopy for infertility. Temporary ovarian suspension to the anterior abdominal wall was performed as the last step in the surgical procedure. It was done in an attempt to separate adhesiogenic surfaces during the initial phase of tissue healing (5-7 days). No complications occurred. After excluding patients who had additional infertility factors and/or were of advanced reproductive age, nine women tried to conceive spontaneously. Of these, five conceived (55%): three delivered, one pregnancy continues (80%), and one woman had an ectopic pregnancy (20%). Of the remaining 15 patients who failed to conceive spontaneously, 5 had a second-look laparoscopy. In four patients (80%), we found no evidence of recurrent adhesions. The remaining 20% had minimal adhesions. Temporary ovarian suspension appears to be simple and safe, and may be effective in preventing postoperative adhesions near the ovaries after operative laparoscopy for advanced endometriosis.
STUDY OBJECTIVE: The presence of fimbrial pathology in advanced endometriosis is clearly understood. However, little is known about the prevalence of fimbrial pathology in early stages of endometriosis. The purpose of this study is to determine the prevalence of fimbrial pathology in patients with infertility with early stages of endometriosis. DESIGN: Historical cohort study (Canadian Task Force classification II/III). SETTING: Tertiary referral center. PATIENTS: The study group (Group 1) consisted of 315 infertile women who were found to have stage I or stage II endometriosis, and the control group (Group 2) consisted of 152 infertile women without endometriosis (Group 2). INTERVENTION: Laparoscopic evaluation for the presence and type of fimbrial pathology. MEASUREMENTS AND MAIN RESULTS: The prevalence of fimbrial pathology was significantly higher in infertile patients with early stages of endometriosis (50.2%) compared with infertile patients with no endometriosis (17.8%, p <.0001). CONCLUSION: These preliminary data suggest the presence of fimbrial pathology in many patients with early stages of endometriosis. Such pathology may act as a mechanical factor interfering with the ovum pick-up mechanism.
