Pelvic pain and differential diagnosis

  1. 1. Acute Pelvic Pain History,Examination,Differential Diganosis and Pelvic Pain
  2. 2. Introduction • Pelvic pain is discomfort in the lower abdomen – Below the umbilicus • may originate in – reproductive organs (cervix, uterus, uterine adnexa) – or other organs ● Urological ● Gastrointestinal ● Musculoskeletal ● Neuropathic ● Other • Sometimes the cause is unknown
  3. 3. Objectives 1. Understand the definition & terminology 2. Identify the causes & form a differential diagnosis 3. Clinically evaluate a patient with this problem
  4. 4. Causes Pelvic pain 1. Gynae cause • Cyclical • Discrete 2. Non-gynae cause • Other organs
  5. 5. • Pelvic region
  6. 6. • Female pelvis
  7. 7. • Vulva
  8. 8. Definitions • Acute pelvic pain: symptom of underlying tissue injury. • Chronic pelvic pain: pain becomes the disease – Recurrent, unrelated to menses, intercourse, pregnancy Chronic pain: pain lasting 6 months or longer. • Chronic pelvic pain syndrome: chronic pelvic pain causing emotional and behavioral changes.
  9. 9. Pelvic Inflammatory Disease • Upper genital tract infection – Endometritis – Salpingitis – Oophritis – Parametritis – Tubo-ovarian abscess – Pelvic peritonitis
  10. 10. Types • Acute – Mild – Moderate – Severe • Chronic
  11. 11. Causes • Primary – STI: chlamydia, trachomatis, neisseria gonorrhoea – Ascending endogenous anaerobes: bacteria, mycoplasma hominis – Latrogenic: IUD insertion, D & C, manual removal of placenta – Following delivery or miscarriage • Secondary – Frrom nearby organs – Through blood stream
  12. 12. Defence mechanism against ascending infection • Vulva – Closure of introitus by labia – Secretion of apocrine gland of vulva has fungicidal effect • Vagina – Closure of apposition of its anterior and posterior walls – Well developed stratified squamous epithelium,unbroken by entrance of glands – Mucosal immune response
  13. 13. • Cervix – Functional closure by cervical mucous • Uterus – Periodic shadding of endometrium – Harbour non-pathogenic anaerobic streptococci
  14. 14. Patient Identification • Name: • Age: • Gravida , Parity • Address • Marrietal status • Her Husband name and work
  15. 15. History Example • Date and time of admission • Complaint: Pain over abdomen especially on LIF, pain: intermittent, gripping, and then sudden severe on LIF and radiate to back • Aggreviate by lying and relieve by lateral position • No history of relivant pain before • Mass over LIF but not notice until pain
  16. 16. • Vaginal White Discharge: 5 days before pain • No post coital pain • LMP: • EDD: • MBD: • Age of menache: ___ year, no history of amenorrhoea, or dysmenorrhoea • No history of AN care, and ATT
  17. 17. • No fever, no fating attack, no labour pain • No bowel and urinary symptoms: no frequency,urgency, dysuria, UTI • No associate with BPV • No loss PV • History of constipation off and on(+)
  18. 18. • Before 2nd pregnancy, OC pill x 5 year , and stopped x 1 year with regular menstruation • POH: – P1- year, NVD at home, alive, birth weight about 1 kg, no complication 1st,2nd,3rd stage complication – G2- unexpected but wanted
  19. 19. Investigation • Blood for CP • USG scan: twisted tumour over LIF and EGA 14 weeks gestation(viable single fetus)
  20. 20. • Mass: urgently surgeried, no complication after surgery such as rupture scar, haemorrhage, or infevtion • To differentiate other differential: – Loss of appitide(+) but no significant weight loss – No infection, or PID disorder: UTI – No history of miscarriage, no vaginal ulcer, no vaginal bleeding – No foul smelling discharged • Provisional Dx: year, G2, P1+0, twisted ovarian cyst with viable 14 weeks pregnancy
  21. 21. Examination Example • Well alert, and good cooperation, no dysponea, no anaemia and jaundice • Abdomen: soft, uterus 14 weeks size, mass(10x8cm) in Lt lower abdomen, mobile, firm, no tender • No FF, No RT • Bowel sound (+) • No loss PV
  22. 22. • VE: – Cervix- firm, close. – Uterus- 14 weeks size, cleft between mass and uterus(+) – Lower pole of mass: felt in Rt cul, tender Lt cul, POD- clear – No loss PV • Provisional Dx: year, G2, P1+0, twisted ovarian cyst with viable 14 weeks pregnancy
  23. 23. Clinical Feature(Acute) • Abdominal and pelvic pain • Deep dyspareunia • Chronic vaginal and cervical white discharge • Heavy and intermenstrual bleeding per vagina • Urinary symptoms-frequency,urgency,dysuria • Constitutional symptom- fever,malaise,nausea,vomitting,constipation
  24. 24. • General: Pyrexia • Abdominal examination: – Distension of lower abdomen – Tenderness, rebound tenderness – Rigidity, guarding • VE: – Mucopurulent discharge through cervix – Cervical motion tenderness – Uterine tenderness – Adnexal tenderness – Unilateral or bilateral adnexal swelling
  25. 25. Complication – Cervicitis – Endometritis – Salpinitis – Salpingo-oophritis – Pelvic peritonitis – Peritubal and peri-ovarian adhesion – Inflammatory tubo-ovarian mass with omental adhesion – Tubo-ovarian abscess
  26. 26. Differential Diagnosis • Ectopic pregnancy • Endometriosis • Ovarian accident – Torsion – Rupture • Appendicitis • Ovulation pain(bleeding corpus luteum) • UTI - Pyelitis, cystitis • Other cause of acute abdomen - inflammatory bowel disease, bowel torsion • Psychosomatic pain
  27. 27. Rule out pregnancy! REPRODUCTIVE AGE GROUP
  28. 28. Pain related to menstrual cycle • Pain related to menstrual cycle • Primary dysmenorrhoea • Endometriosis • Pelvic inflammatory disease • Mittleschmerz • Unrelated to menstruation • Pelvic inflammatory disease • Endometriosis • Fibroids • Cysts
  29. 29. • ENDOMETRIOSIS
  30. 30. • Sites

  39. 39. • ADENOMYOSIS
  40. 40. Definition • Ectopic endometrial tissue within the myometrium • Older age group than endometriosis patients • Associated with any sort of uterine trauma that may break the barrier between the endometrium and myometrium
  41. 41. Symptoms • Similar to endometriosis and other pelvic pathology – Pain more likely to be suprapubic – More likely to have abnormal bleeding • Usually older patient • Less likely to be infertile • May have secondary infertility • Previous pregnancies or procedures to uterus • Mimic fibroids – frequently coexist

  47. 47. • FIBROIDS
  48. 48. Definition • Noncancerous growths of the uterus • Often appear during childbearing years • Also called fibromyomas, leiomyomas or myomas • Mostly discovered incidentally
  49. 49. • Locations
  50. 50. Symptoms • Heavy menstrual bleeding – Usually cyclical – Prolonged menstrual periods – seven days or more of menstrual bleeding – More likely to be associated with anaemia • Pelvic pressure or pain • Frequent urination • Constipation• Backache or leg pains
  51. 51. • Subserosal
  52. 52. • Multiple fibroids
  53. 53. Pain • Rarely, a fibroid can cause acute pain – when it outgrows its blood supply • Deprived of nutrients, the fibroid degenerates • Causing pain and fever • Pedunculated fibroids can trigger pain by twisting on its stalk and cutting off its blood supply
  54. 54. • Pelvic inflammatory disease/pelvic infectionPID
  55. 55. Definition • Pelvic inflammatory disease (PID) - infection of the female reproductive organs• Occurs when sexually transmitted bacteria spread from the vagina to the uterus and upper genital tract • Important to avoid because it can result in infertility or ectopic pregnancy • Prompt treatment of a sexually transmitted disease can help prevent PID.
  56. 56. Causes • Unsafe sexual practices • IUDs may increase risk of PID • Barrier method, such as a condom, reduces the risk • Bacteria may also enter the reproductive tract as a result of an IUD insertion, childbirth, miscarriage, abortion or endometrial biopsy • Most common – Chlamydia – Gut organisms – Fungal
  57. 57. • Liver adhesions
  58. 58. • Uterine adhesions
  59. 59. Complications • EP • Infertility • Chronic pelvic pain
  60. 60. • PID
  61. 61. Symptoms • Pain in the lower abdomen and pelvis • Heavy vaginal discharge with an unpleasant odor • Irregular menstrual bleeding • Dyspareunia • Low back pain • Fever, fatigue, diarrhea or vomiting• Painful or difficult urination
  62. 62. PID
  63. 63. • EVALUATION
  64. 64. • Differential Diagnosis for Chronic Pelvic Pain – Gynecologic • Endometriosis • Adhesions – Endometriosis – PID • Adenomyosis • Leiomyomata – Gastrointestinal • Irritable bowel • Inflammatory bowel disease • Chronic appendicitis •Diverticulosis •Meckel’s diverticulum
  65. 65. HOCI • Rule out pregnancy • Gynecologic history – onset, duration, location, and character of pain – gravity, parity, menstrual history, history of STI – Severity of pain & its relationship to the menstrual cycle • Important associated symptoms – include vaginal bleeding – vaginal discharge – symptoms of hemodynamic instability (eg, dizziness, light- headedness, syncope or near- syncope)
  66. 66. Types of pain • Visceral pain • Referred Pain • Somatic Pain • Myalgia • Hyperalgesia • Neuroinflammation
  67. 67. System review • Seek symptoms suggesting possible causes – morning sickness, breast swelling or tenderness, or missed menses (pregnancy) – fever and chills (infection) – abdominal pain, nausea, vomiting, or change in stool habits (GI disorders) – urinary frequency, urgency, or dysuria (urinary disorders)
  68. 68. Past history • Note history of – Infertility – ectopic pregnancy – pelvic inflammatory disease – Urolithiasis – Diverticulitis/GI prolems • Any previous abdominal or pelvic surgery should be noted
  69. 69. Physical examination • Begins with review of vital signs for signs of instability – eg, fever, hypotension • Focus on abdominal and pelvic examinations • Begin with inspection
  70. 70. • Thrombosis of the Inferior Vena Cava and Dilated Veins of the Trunk
  71. 71. Abdominal examination • Palpation for – Tenderness – Masses – peritoneal signs • Location of pain and any associated findings may provide clues to the cause • Rectal examination is done to check for tenderness, mass, and occult blood.
  72. 72. Pelvic examination • Inspection of external genitals, speculum examination, and bimanual examination • Cervix - inspected for discharge, uterine prolapse, and cervical stenosis or lesions • Bimanual examination - assess cervical motion tenderness, adnexal masses or tenderness, and uterine enlargement or tenderness
  73. 73. Investigations • Pregnancy tests • Urinalysis • Ultrasonography • Blood tests
  74. 74. • Ultrasound hydosalpinx
  75. 75. • Lap endometriosis
  76. 76. • KEY POINTS
  77. 77. Key points 1. Pelvic pain is common and may have a gynecologic or nongynecologic cause. 2. Pregnancy should be ruled out in women of childbearing age. 3. Quality, severity, and location of pain and its relationship to the menstrual cycle can suggest the most likely causes. 4. Dysmenorrhea is a common cause of pelvic pain but is a diagnosis of exclusion
