While anal sphincter neurogenic injury documented by needle electromyography (EMG) has been implicated to cause fecal incontinence (FI), most studies have been uncontrolled. Normal values and the effects of age on anal sphincter motor unit potentials (MUP) are ill defined. The functional significance of anal sphincter neurogenic injury in FI is unclear. Anal pressures and EMG were assessed in 20 asymptomatic nulliparous women (age, 38 ± 5 yr; mean ± SE) and 20 women with FI (54 ± 3 yr). A computerized program quantified MUP duration and phases. These parameters and MUP recruitment were also semiquantitatively assessed by experienced electromyographers in real time. Increasing age was associated with longer and more polyphasic MUP in nulliparous women by quantitative analysis. A higher proportion of FI patients had prolonged (1 control, 7 patients, P = 0.04) and polyphasic MUP (2 controls, 9 patients, P = 0.03) at rest but not during squeeze. Semiquantitative analyses identified neurogenic or muscle injury in the anal sphincter (11 patients) and other lumbosacral muscles (4 patients). There was substantial agreement between quantitative and semiquantitative analyses (κ statistic 0.63 ± 95% CI: 0.32–0.96). Anal resting and squeeze pressures were lower ( P ≤ 0.01) in FI than controls. Anal sphincter neurogenic or muscle injury assessed by needle EMG was associated ( P = 0.01) with weaker squeeze pressures (83 ± 10 mmHg vs. 154 ± 30 mmHg) and explained 19% ( P = 0.01) of the variation in squeeze pressure. Anal sphincter MUP are longer and more polyphasic in older than younger nulliparous women. Women with FI have more severe neurogenic or muscle anal sphincter injury, which is associated with lower squeeze pressures.

Operative Vaginal Delivery

Background: Anal incontinence is an embarrassing condition that is largely underreported. Obstetric anal sphincter injuries are the most important etiological factors. Anal sphincter injury during delivery is considered to be one of the major risk factors for fecal incontinence in women. After anal sphincter injury at the time of delivery, up to 50% women have complaints of fecal incontinence, mainly because of persisting sphincter defects. Objectives: To evaluate the risk factors for the occurrence of obstetric anal sphincter injuries during vaginal delivery. To evaluate the outcome of patients with obstetric anal sphincter injuries. Methodology: A retrospective descriptive study was conducted from 2014 to 2016. Data of all patients with Obstetric Anal Sphincter Injuries (OASIS) over 3 years was collected from the medical record section after ethical clearance from Institutional Review Committee (IRC), BPKIHS. The data was entered in the excel sheet and analyzed using SPSS 17. Results: The Most important risk factor of OASIS was operative vaginal delivery (vacuum assisted vaginal delivery), followed by birth weight of the baby greater than 3.5 Kg and primigravida. Conclusion: Patients undergoing operative vaginal delivery, primigravida and birth weight greater than 3 kg are the important risk factors for OASIS. So, patients with these conditions should be handled carefully during second stage of labor to prevent the occurrence of OASIS.
