Comparison of salpingectomy and tubal detorsion procedures after experimental ischemia-reperfusion injury in a rat fallopian tube model: biochemical and histopathological evaluation.

OBJECTIVE: To compare salpingectomy and detorsion procedures and investigate the biochemical and histopathological changes in the fallopian tubes in the experimentally isolated fallopian tube torsion model in rats. DESIGN: Experimental study. SETTING: Experimental surgery laboratory in a training and research hospital. ANIMAL(S): Twenty-seven Sprague-Dawley rats in the reproductive period. INTERVENTION(S): Group 1, control group (n = 6); group 2, bilateral total salpingectomy group after 4 hours of tubal ischemia (n = 7); group 3: 4 hours of bilateral tubal ischemia plus 1 week of reperfusion (n = 7); and group 4, 4-hour period of bilateral tubal ischemia plus 30 days of reperfusion (n = 7). A 22-gauge catheter was administered before and after surgery using methylene blue through the uterine horn of the rat to evaluate tubal patency. MAIN OUTCOME MEASURE(S): Preoperative and postoperative serum antimüllerian hormone (AMH) levels, histopathological examination of the rat tuba uterine and histopathological damage scores, antioxidant compounds (superoxide dismutase [SOD], catalase, and glutathione peroxidase [GSH-Px]), and oxidative stress end product levels (malondialdehyde [MDA] and 8-hydroxy-2'-deoxyguanosine [8-OHdG]). RESULT(S): Although a significant difference was observed in the tissue SOD, GSH-Px, MDA, and 8-OHdG values, no significant difference was observed between the groups in serum samples. The tissue SOD and tissue GSH-Px levels in group 2 significantly decreased, and a significant increase was observed in the tissue MDA and 8-OHdG values in group 2. Among the histopathological parameters, epithelial changes, vascular congestion, and the total fallopian tube mean damage score of 4 showed a significant decrease in group 4. When the methylene blue transitions before and after ischemia-reperfusion injury were compared, the values of the methylene blue transition after ischemia-reperfusion injury in groups 2-4 significantly decreased. When the serum AMH levels were analyzed, the postoperative AMH value in group 2 significantly increased. CONCLUSION(S): This study reveals that biochemical and histopathological improvement is observed in the fallopian tube tissues gradually when the detorsion procedure is performed for the necrotized tubal tissue instead of salpingectomy. Although there is restoration of epithelial integrity after reperfusion, tubal passage remains absent. CLINICAL TRIAL REGISTRATION NUMBER: This study was approved by the Local Ethics Committee for Animal Experiments of the Health Sciences University, Istanbul Hamidiye Medicine Faculty (approval number 27.05.2022-9269). The study followed the ethics standards recommended by the Declaration of Helsinki.

Pseudo-pseudo Meig's syndrome presenting as an acute surgical abdomen: A rare entity and review of the literature.

AIM: Pseudo-pseudo Meigs' syndrome is a rare entity of systemic lupus erythematosus, which is defined with the combination of pleural effusion, elevated serum CA-125 levels, and ascites. It has similar clinical aspects with gynecological malignancies which may lead gynecologists to perform unnecessary surgeries and lab workouts. This review seeks to point out the importance of diagnosing pseudo-pseudo Meig's syndrome (PPMS) and endeavors to inform gynecologists about the differential diagnoses. METHODS: This article includes a review of the literature on different cases of PPMS. We searched the PubMed database using the search terms in various combinations "Pseudo-pseudo Meig's syndrome," "Tjalma syndrome," and "SLE." RESULTS: According to the current literature, a majority of internal medicine specialists recognized this clinical condition in the past few years and discussed PPMS as a new onset of systemic lupus erythematosus. PPMS is one of the disregarding entities where gynecologists do not consider it as a differential diagnosis in case of less awareness. When a gynecologist evaluates ascites manifesting as acute abdomen; ectopic pregnancy, ovarian hyperstimulation syndrome, cyst rupture, and malignancy come to mind first. Four-thirds of those patients evaluated by gynecologists were performed hysterectomy leading to unnecessary interventions and economic burden on the health system. CONCLUSION: Although the mechanism is unrevealed and remains unclear, PPMS has been noticed in the literature for the past few years. In order to prevent unnecessary interventions, this syndrome should be considered as a differential diagnosis.
