Regarding “Complete Resection of Retroperitoneal Ectopic Pregnancy Adherent to the Inferior Vena Cava by Laparoscopy”

Abstract

Tong et al [ 1 Tong A Pu Y Ye J Qi X. Complete resection of retroperitoneal ectopic pregnancy adherent to the inferior vena cava by laparoscopy. J Minim Invasive Gynecol. 2022; 29: 810-811 Abstract Full Text Full Text PDF PubMed Scopus (2) Google Scholar ] shot an excellent article describing an accurate surgical dissection of a retroperitoneal ectopic pregnancy (EP) on the inferior vena cava and the approach to treating the unusual EP site. This article asserts how the laparoscopic approach represents safe and effective management of unconventional EP sites. We considered that, in this context, it would have been interesting to also evaluate a recent work in which we described a case of laparoscopically treated retroperitoneal pregnancy [ 2 Di Lorenzo G Romano F Mirenda G et al. “Nerve-sparing” laparoscopic treatment of parametrial ectopic pregnancy.

Authors’ ReplyJournal of Minimally Invasive GynecologyVol. 29Issue 8PreviewDi Lorenzo et al [1] suggested that it was important to recognize the retroperitoneal ectopic pregnancy (REP) early and identify its risk factors, such as endometriosis. However, there was no sign of endometriosis in our case, but consolidation of the right fallopian tube lumen that was found suggested that the dysfunction of transportation for fertilized eggs might lead to ectopic implantation [2]. There are 3 main hypotheses of REP: (1) the retroperitoneal sinus hypothesis, (2) the peritoneal erosion hypothesis, and (3) the intralymphatic migration hypothesis [3]; our case seemed to meet the second hypothesis given that the fertilized eggs were unable to enter the uterine cavity and were implanted in the retroperitoneum instead.

Laparotomy is recommended for REP removal because it is difficult to control bleeding and remove lesions completely with laparoscopy [2]. However, few successful laparoscopic resections have been reported in recent years [3,4]. To share the experience of diagnosis and surgery, we present a rare case of REP adherent to the inferior vena cava, which was completely resected by laparoscopy. Full-Text PDF
