General GYN Flashcards
What is the difference between anal incontinence and fecal incontinence?
Anal incontinence: loss of flatus with or without stool
Fecal incontinence: recurrent involuntary loss of solid/liquid stool from the rectum
How common is fecal incontinence?
What are causes and risk factors?
7-15%.
Causes:
- increased parity
- higher order perineal laceration
- chronic constipation
- incomplete repair of 3rd/4th degree laceration
- pelvic floor weakness
- Neurologic: spinal cord injury, CVA
- Non-neurologic: more common. Lacerations, IBD, chronic diarrhea, constipation w/ overflow, rectal prolapse/hemorrhoids, systemic dz (DM, urinary incontinence)
What are risk factors for fecal incontinence?
What are meds associated with it?
obesity, smoking, increased age, hx anal intercourse, chronic illness, increased parity, hx 3rd/4th degree laceration, use of forceps, midline episiotomy
Meds associated with loose stool/fecal incontinence: antibiotics (fluoquinolones, cephalosporins), prostaglandins (hemabate/misoprostol), laxatives, metformin
What is the treatment for fecal incontinence?
correct underlying issue. PFPT, pads/diapers, dietary changes (identify triggers), adjust meds, anti-diarrheal, sacral nerve stimulation or surgery.
Which distension media are available:
Electrolyte-containing: LR, NS. Cannot use with monopolar bc they conduct electrical current.
- max deficit is 2500
Electrolyte-poor:
Dextrose, glycine, sorbitol, mannitol (not metabolized=iso-osmolar).
- can cause hyponatremia if large volume used.
- deficit is 1500L
How would you evaluate a confused/disoriented pt after hysteroscopic myomectomy?
Concern for hyponatremia, pulm edema (Crackles), fluid overload w/ hyponatremia. Vitals w/ O2 sats. Stat CBC, BMP, CXR. Check op report for fluid deficit
If electrolyte imbalances, correct those.
If crackles on exam, CXR w/ pulm edema, start diuretic
What fluid deficit would concern you? 1000 for glycine/sorbitol/mannitol.
How would you manage the patient with hyponatremia after hysteroscopy?
Admit for observation for fluid overload and hyponatremia (due to use of hypo-osmotic fluid media or non-electrolyte fluids if using electrosurgical monopolar energy)
Check for hyperammonia (if 3% glycine used as opposed to Sorbitol or Mannitol for fluid media)
Can still have significant fluid volume overloads using isotonic fluids with bipolar energy resectoscopes as well
Follow I&Os, place Foley catheter
Give Lasix to begin diuresis
Check electrolytes, especially sodium – If low, start NS. If significantly low sodium (<110) consider 3% saline given very slowly to replace
- replace sodium slowly 1-2mEq/hr.
Pulse oximetry, if <90% consider CXR, diureses
Follow neurological symptoms; seizures, CNS changes
How would patient present if you used isotonic fluid?
How could you prevent this in future procedures?
Fluid overload (CHF). Less common w/ electrolyte abnormalities.
Hyponatremia is more common w/ hyper-osmolar fluids. So use NS or LR. Limit surgery to less than 1 hr. Monitor the quantity of fluid absorbed, limit IVF. Max is 2500, stop sooner if pt older.
Risks of hysteroscopy: uterine perforation, hyponatremia, infection, creating false passage.
Discuss the steps of a hymenectomy
When is hymenectomy indicated?
Dorsal lithotomy position, perineum prepped draped. stellate/cruciate incision to open hymen. Gentle irritation. Hymenal tags grasped w/ tissue forceps. Each hyental tag elevated and excised at introital level. Base sutured w/ interrupted 3-0 synthetic absorbable suture.
See steps of transverse vaginal septum!!!
Indicated if imperforate hymen (causing hematocolpos) or perforated hymen w/ hymenal hypertrophy obstructing intercourse (can cause hemorrhage 2/2 lateral pudendal artery).
Oliguria after TAH w/ EBL 2L and transfusion.
What diagnostic studies would you order and why?
CBC, BMP.
- Cr to evaluate for kidney injury to rule out AKI (>1.0).
- Orthostatics.
- UA (muddy brown casts)
- FeNA. pre-renal <1.0. ATN >2.0. 1-2 is inconclusive.
- Renal US.
What is ATN and how is it diagnosed and treated?
Loss of concentrating ability. Early finding.
- Renal ischemia (most common causes), sepsis, nephrotoxins.
- Ischemic ATN lasts 7-21d, return to baseline usually. Diuretics don’t help renal perfusion.
- Supportive management w/ adequate perfusion, avoid hypovolemia. Discontinue nephrotoxic meds, non-contrast imaging only. May require temporary dialysis.
What are causes of oliguria?
Pre-renal: IVF resuscitation.
Intrinsic renal issue
Post-renal obstruction
How do patients with necrotizing fasciitis present?
What antibiotics cause it?
What is management?
Infection of deep soft tissues, progressive destruction of muscle, fascia. Muscle tissue spared 2/2 good blood supply.
2/2 E. Coli, Klebsiella, enterococci, clostridium, bacteroides
Erythema w/o sharp margins, edema, severe pain out of proportion to exam, fever, crepitus, necrosis
Labs: nonspecific.
Diabetes and trauma increase risk
Broad spectrum antibiotics (vanc/zosyn), to OR for debridement as this is a surgical emergency. Can lead to limb loss/death. Early recognition=critical.
What is GTD?
Gestational trophoblastic disease
- spectrum of cell proliferations arising from placental villous trophoblast:
1. Hydatidiform mole (complete and partial)
2. Invasive mole
3. Choriocarcinoma
4. Placental site trophoblastic tumor (PSTT)
Describe a partial vs complete mole
PARTIAL
- karyotype 69 XXX or 69 XXY
- maybe fetus present
- uterine size SGA
- rare theca-lutein cysts
- GTN risk rare (<5%)
COMPLETE
- karyotype 46 XX or 46 XY
- absent fetus (on villi w/ POCs)
- LGA uterine size
- common theca lutein cysts (2/2 high hCG levels0
- GTN risk 15-20%
*molar pregnancies associated w/ associated w/ anemia, infection, hyperthyroid and coagulopathy
When is there concern for post molar GTN?
If post evacuation HCG levels plateau at 10-20 mIU/ml. What is your management?
increasing hcg >10% across 3 values
Plateauing hcg 4 measurements within 10% of each other across 3 weeks.
Plateau at low levels is consistent with “phantom HCG”, which are nonspecific heterophilic antibodies. They are not excreted in the urine, so check a UPT to exclude a false + HCG before subjecting patient to chemotherapy for GTN.
What is treatment of molar pregnancy?
- Suction D&C + sharp curettage or hyst if no desired fertility
- HYST if: age <40, S>D, hCG >100K, bilateral theca lutein cysts >6cm (bc all incr risk GTN)
- early US for all future pregnancies (recurrence risk 1% after 1 and 15% after 2 prior moles)
Post-op follow up:
- reliable contraception
- weekly HCG until negative (for partial stop when first negative obtained, for complete once neg, do monthly x 3 mo)
What is GTN?
What is the treatment?
gestational trophoblastic neoplasia. Malignant proliferation of placental trophoblastic tissue
- invasive mole, choriocarcinoma, placental site trophoblastic tumor, epithelioid trophoblastic tumor
- FIGO staging system (first 3 are indicators of hcg level)
- age
- duration from prior pregnancy
- type of prior pregnancy (abortion vs full term)
- pre-treatment HCG level
- largest tumor size
- site/number of mets
- history of failud chemo
Treatment:
- single agent MTX vs. actinomycin d for low-risk disease.
- multiagent EMACO (etoposide, MTX, actinomycin d, cyclophosphamide, vincristine) for high risk
How would you manage black implants in posterior cul de sac on laparoscopy?
management of implant disease.
- remove small implants but avoid managing advanced disease (implants near bowel serous, vascular structures or ureter)
- I would remove implants using bipolar cautery or excision biopsy.
- Post op management: suppression w/ OCPs, progestin only methods, LN-IUD
What are indications for inpatient management of PID?
- acute peritoneal signs on exam
- pregnancy
- failure of outpatient management
- TOA
- pt inability to comply w/ outpatient management
- pt N/V and unable to tolerate oral meds
What should you consider when choosing an abdominal incision?
Prior operation w/ suspected adhesion/scarring
Presence of large mass in operative field
Body habits
- prior operation w/ graft (hernia repair) in area of incision
