d. surgical obstruction after partial salpingectomy, tubal ligation
e. tubal surgery:
microsurgery, reversal of sterilization, previous tubal pregnancy
2. Assisted conception: in-vitro fertilization if tubes are damaged but patent
3. Overdevelopment of the ovum: external migration
4. Endometriosis of the tubes and ovaries

Differential diagnosis
1. Threatened or Incomplete abortion - history of amenorrhoea + - bleeding PV - pain varies
2. Bleeding Corpus Luteum - diagnosis difficult - usually no overdue - laparoscopy necessary
3. Accidents to Ovarian Cysts - no overdue

Management of Ectopic Pregnancy
Acute
a. Resuscitation: - keep quiet, flat - injection morphia - IV line - blood rapidly
b. Surgery - immediate laparotomy - autotransfusion - salpingectomy
![Page 15: Ectopic pregnancy : house officer 's presentation](https://reader030.vdocuments.mx/reader030/viewer/2022013100/554b164cb4c90562098b4d4a/html5/thumbnails/15.jpg)
Chronic Cases
- Admission- operative procedures a. laparoscopic surgery
- unruptured ampullary or infundibular
-pregnancy < 3 cm in diameter
- salpingotomy - intratubal methotrexate injection - salpingectomy
![Page 16: Ectopic pregnancy : house officer 's presentation](https://reader030.vdocuments.mx/reader030/viewer/2022013100/554b164cb4c90562098b4d4a/html5/thumbnails/16.jpg)
b. laparotomy
- salpingectomy
- salpingotomy
- milking of the tube
Non- operative procedure Puncture and aspiration of gestational sac,
local PG, KCL, hyperosmolar glucose, methotrexate
Expectant management (non interventional )

Cornual pregnancy - diagnosis difficult - can have profuse intraperitoneal
bleeding - hysterectomy may be necessary
