Aim: To investigate the distribution of tubal endometriosis (EM) in the right and left sides and four parts of the fallopian tube. Methods: A retrospective, cross‐sectional study was conducted on patients with tubal EM at the Fourth Affiliated Hospital of Guangxi Medical University from October 2011 to September 2021. Chi‐square and binomial tests were used for analysis. Results: Thirty‐four patients (53.97%) had tubal resection due to EM (EM group). Twenty‐nine patients (46.03%) had tubal resection due to non‐EM (non‐EM group). Thirty‐two patients (50.80%) had left fallopian tube EM, 21 (33.33%) had right fallopian tube EM, and 10 (15.87%) had bilateral fallopian tube EM, with significant differences among them (p = 0.000). In the EM group, 15 patients (44.12%) had left fallopian tube EM, 13 (38.23%) had right fallopian tube EM, and 6 (17.65%) had bilateral fallopian tube EM (p = 0.052). In the non‐EM group, statistically different (p = 0.001) diagnoses of left fallopian tube EM, right fallopian tube EM, and bilateral fallopian tube EM were 17 (58.62%), 8 (27.59%), and 4 (13.79%), respectively. In the EM group, 18 patients (52.94%) were in the ampullary region; 16 (47.06%) were in the nonampullary region (p = 0.864). In the non‐EM group, 22 cases (75.86%) were in the ampullary region and 7 (24.14%) were in the nonampullary region, with a significant difference between them (p = 0.008). Conclusions: The incidence of left fallopian tube EM was higher than that of right and bilateral fallopian tube EM. The incidence of tubal ampullary EM was higher than that of nonampullary region.

Aim: Ectopic pregnancy implantation on the tubal stump after salpingectomy is a rare location for extrauterine pregnancy, whose pathogenesis is still unknown. The purpose of this study was to examine whether the time interval elapsed from salpingectomy may predispose the embryo to implantation on the tubal stump in the next pregnancy subsequent to tube removal. Methods: Nine women operated for stump pregnancy (study group) between 2008 and 2019 were retrospectively identified. For each case in the study group, 12 consecutive cases that underwent laparoscopic salpingectomy constituted the control group. A sample size of 100 control patients was calculated to achieve statistical power (97.8%) and an α of 0.05. The control groups were triple‐matched with the study group for patients' age, indications for salpingectomy (tubal pregnancy or hydrosalpinx prior to in vitro fertilization treatment) and mode of conception of the subsequent pregnancy following salpingectomy. Results: Nine women underwent surgery for stump pregnancy during the study period. All women had a surgical history of laparoscopic salpingectomy. The time interval from prior salpingectomy to subsequent pregnancy was significantly shorter in study group than in the control group (4.3 ± 2.1 months vs. 15.6 ± 13.7 months, respectively, p = 0.016). Conclusion: A possible association between the short time interval from prior salpingectomy to ectopic implantation on the tubal stump in the subsequent pregnancy was found. The clinical implications of these findings and in particular whether patients should be advised to wait at least 4 months from the salpingectomy to the subsequent pregnancy remain unclear.

Aim: To present our experiences in isolated fallopian tubal torsion (IFTT) case series, which are difficult to diagnose, in light of the literature. Methods: The data of the patients diagnosed with IFTT surgically in our tertiary hospital between 2018 and 2019 were evaluated. Results: Abdominal lower quadrant pain was present in all nine cases. Abdominal pain was accompanied by nausea in five of the nine cases with vomiting in four of the nine cases. Seven of the patients had pain radiating to the vagina. Only one case of IFTT was diagnosed with transvaginal ultrasonography where left tubal dilation and free fluid in the abdomen was found. Two of the nine cases were operated on with a preoperative diagnosis of IFTT. Seven cases were approached laparoscopically and two cases underwent a laparotomy. During the treatment, two of the nine cases underwent detorsion, while seven of the patients underwent a salpingectomy. Conclusion: IFTT is a very rare condition. Therefore, it is difficult to diagnose as it does not come to mind at first glance. Delay of the operation reduces the chance of preserving the tube. [ABSTRACT FROM AUTHOR]
