who underwent operative hysteroscopy between November 2015 and April 2017.

Methods: A prospective case series was undertaken among all patients with infertility The outcome measures included the frequency and type of operative hysteroscopy and the reproductive outcome. Results: The series included 159 women, 70.4% (n=112) of whom had abnormal findings at hysteroscopy. A total of 162 operative hysteroscopic procedures were performed; the most common procedures were adhesiolysis (76 [46.9%]), polypectomy (28 [17.3%]), and septum resection/incision (17 [10.5%]). The instruments used were mainly scissors (65 [40.1%]) and a resectoscope (52 [32.1%]). Complete removal of the lesions was achieved in 86.4% (n=140) of the procedures and a normal cavity in 87.0% (n=141). The complication rate was 6.8% (n=11); the most common complication was minor hemorrhage (5 [3.1%]). The main challenges included poor distention (10 [6.2%]) and poor vision (8 [4.9%]). Menstrual normalization was achieved in 64 (40.3%) of the patients, the cumulative pregnancy rate was 19.5% (n=31), and the live birth rate was 3.8% (n=6). Conclusion: Operative hysteroscopy was feasible and safe in the present resource-­ poor region. There is a need to build capacity for the performance of hysteroscopy to facilitate the management of infertility in the region. KEYWORDS
