The histopathology of 110 cases of tubal gestation was reviewed. No evidence was found of the development of the gestation into the tubal muscularis and beneath the overlying peritoneum. The localized tubal mass identified clinically was secondary to luminal distention. It was clear that tubal rupture occurred secondary to localized distention and vascular compromise with hemorrhagic necrosis and was not secondary to invading chorionic villi. With conservative linear salpingostomy, the localized tubal damage histologically appeared to be about the same as that seen in spontaneous rupture. Difficulty in controlling bleeding in conservative surgical procedures may well be a reflection of the viability of the villi and implantation of the more vascular, mesenteric side of the tubal lumen.
回顾了110例输卵管妊娠的组织病理学情况。未发现妊娠发展至输卵管肌层及覆盖的腹膜下方的证据。临床上确定的局限性输卵管包块是管腔扩张的继发表现。显然，输卵管破裂是局限性扩张和血管受损继发出血性坏死所致，而非绒毛侵入继发。采用保守性输卵管线性造口术时，组织学上局限性输卵管损伤似乎与自然破裂所见损伤大致相同。保守性手术中控制出血困难很可能反映了绒毛的活力以及输卵管腔血管更丰富的肠系膜侧的着床情况。
