Hysteroscopic surgery is a minimally invasive procedure for the treatment of intrauterine pathologies. However, it can result in fatal complications. We herein report a case of symptomatic hyponatremia and hyperglycemia during hysteroscopic resection of severe intrauterine adhesion with 5% dextrose in water as the distension medium. Because of the difficulty of the incision, the infusion pressure was 100 to 150 mmHg, and surgery was continued for 70 minutes. A total of 19 L of 5% dextrose in water was used as an irrigating fluid. Large-scale absorption of irrigating fluid (3 L) induced dilutional hyponatremia (120 mmol/L) and hyperglycemia (30 mmol/L). Initial signs were abnormal flatulence and postoperative coma. Hypertonic saline, diuretics, insulin, and liquid restriction were the prevailing treatment strategies for hyponatremia and hyperglycemia. Ionized calcium and potassium levels decreased during treatment. We emphasize the importance of prevention, recognition, and a meticulous perioperative treatment standard. Surgical teams must be vigilant in fluid deficit monitoring and serum electrolyte analysis.

The pathogenesis and therapeutic treatment of intrauterine adhesions (IUAs) remain unsolved, highlighting the need for stable and effective experimental animal models. In this study, uterine electrocoagulation of twenty-one female New Zealand White rabbits was carried out to establish an IUA model. As rabbits have two completely separate uterine horns, each rabbit had its own internal control: one uterine horn was given an electrothermal injury (Group A, n=21), and the contralateral uterine horn received no treatment and served as the control (Group B, n=21). The endometrial morphology, number of endometrial glands, area of endometrial fibrosis, and number of implanted fetuses were compared between the two groups. In Group A, the numbers of endometrial glands on Days 7 and 14 and the number of implanted fetuses were significantly lower than those in Group B (P<0.05, P<0.05, and P<0.01, respectively), while the ratio of the area with endometrial stromal fibrosis to the total endometrial area was significantly increased (P<0.01). These results suggest that this method of electrothermal injury is effective for the establishment of a rabbit IUA model between 7 and 14 d after surgery.

OBJECTIVETo establish a rabbit double uterine horn model for assessing the time-course of pelvic adhesions and evaluating the effectiveness of different anti-adhesive materials in reducing adhesions.

METHODSA total of 330 Japanese white rabbits underwent laparotomy, followed by uterine horn incision. Animals were euthanized after 3, 7, 14, 28, and 42 days, respectively.

RESULTSThe surgical procedure was smooth. Rabbit double uterine horn model was applied for the evaluation of pelvic adhesions in a three-dimension fashion. Each of the three means-gauze abrasion, needle holder clamping, and direct uterine incision induced postoperative pelvic adhesions, among which direct uterine incision was the best to mimic conditions after gynecological operations. Under normal circumstances, degradation of filmy fibrinous adhesions by locally released proteases of the fibrinolytic system occurred within 3 days of injury. The regeneration of the mesothelium was completed within 7 days. Collagen reached its peak by day 14. Anti-adhesive materials were supposed to be completely absorbed by day 28, and their effectiveness in preventing pelvic adhesions was confirmed at this time point. Whether their effect can be maintained after the absorption of the anti-adhesive materials was investigated in 42 days.

CONCLUSIONSThe animal model was successfully established. It well mimics the postoperative pelvic adhesions after direct uterine horn injury and thus is a suitable model for studying site-specific adhesions. Observations on the 3rd, 7th, 14th, 28th, and 42nd post-operative days provided a full picture of the adhesion formation process.

OBJECTIVE: To depict the cell landscape and molecular biological characteristics of human intrauterine adhesion (IUA) so as to better understand its immune microenvironment and provide new inspirations for clinical treatment. METHODS: Four patients with IUA who underwent hysteroscopic treatment at Dongguan Maternal and Child Health Care Hospital from February 2022 to April 2022 were selected as the study subjects. Hysteroscopy was used to collect the tissues of IUA, which were graded based on the patient's medical history, menstrual history and status of IUA. Library construction, sequencing, single cell data comparison and gene expression matrix construction were carried out in strict accordance with the single cell RNA sequencing process. Thereafter, the UMAP dimension reduction analysis of cell population and genetic analysis were carried out based on the cell types. RESULTS: A total of 27 511 cell transcripts were obtained from four moderately graded IUA tissue samples and assigned to six cell lineages including T cells, mononuclear phagocytes, epithelial cells, fibroblasts, endothelial cells and erythrocytes. Compared with normal uterine tissue cells, the four samples showed different cell distribution, and the proportions of mononuclear phagocytes and T cells in sample IUA0202204 were significantly increased, suggesting a strong cellular immune response. CONCLUSION The cell diversity and heterogeneity of moderate IUA tissues have been described. Each cell subgroup has unique molecular characteristics, which may provide new clues for further study of the pathogenesis of IUA and heterogeneity among the patients.

OBJECTIVETo assess the abdominal cocoon complicated with infertility using laparoscope and its clinical management.

METHODSSix cases of abdominal cocoon treated in our hospital from January 1998 to December 2002 were retrospectively reviewed.

RESULTSOf the 6 patients all with primary and tubal infertility, 3 received routine closed laparoscope operation, and other 3 failed for laparoscopy and were transferred to laparotomy. During the surgery it was found that the abdomen and pelvis were filled with multiple layer fibrous tissue which enveloped the bowel and reproductive organs, making exploration nearly impossible. It was difficult to ablate the envelope.

CONCLUSIONAbdominal cocoon can be diagnosed in those primary and tubal infertile patients when the charge is hindered in the process of laparoscope. The optimal treatment of the infertility for those patients is in vitro fertilization-embryo transfer.

OBJECTIVE: To explore the better operational methods by the laser surgery to treat diseases involving the laryngeal anterior commissure. It can excise the diseases as well as avoid anterior commissure adhesion, laryngostenosis and dyspnea after operations. METHOD: Twelve dogs were divided into 4 groups at random. There were three dogs in one group. A: excising experimental dog's anterior commissure by twice operations, the interval time was two weeks; B: excising experimental dog's anterior commissure in one time, at the same time suturing the silica gel sheet on the anterior commissure; C: excising experimental dog's anterior commissure in one time and then applying MMC on the wound of the anterior commissure; D: excising experimental dog's anterior commissure in one time, without any treatment. RESULT: All of the dog's surgery were completed successfully by laser. Four weeks later, we observed the raw surfaces. A: the neonatal membrane covered the wound, inflammatory reaction slight, we could not see obvious adhesion in the anterior commissure. B: the membrane covered the wound, appearing the dark chronic inflammation, we could see the adhesion in the anterior commissure slight. C: the membrane covered the wound, edematization, we could see the moderate adhesion in the anterior commissure. D: edematization, we could see the adhesion in the anterior commissure obviously. Four groups were all appeared hoarsenesses, the most slightly in group A, secondly in B and C, the worst in D. The analysis of vocal cord length of 4 groups, we used matched-pairs t-test, A, B, C groups' P>0.05, the vocal cord length didn't become shorter than before obviously. Group D's P<0.01, that meant the vocal cord length became shorter obviously. Between each group,we used reiterature-measurement analysis of variance (P<0.05), the change of vocal cord length had disparity in different groups. The comparison in two groups suggested that group A is the best. B and C are inferior ,but no disparity between them. The analysis of glottis area of 4 groups, as the same method above, A,B groups' P>0.05, the glottis area didn't shrink than before obviously. C and D groups' P<0.05, that meant having statistical significance and glottis area shrinked obviously. Between each group, we used reiterature-measurement analysis of variance (P>0.05), we could not think that the changes of four groups have disparity. CONCLUSION Excising the experimental dog's anterior commissure by laser, compared the 4 different operation methods, group A is the best method. B and C are inferior. The results are valuable in clinic when we perform operations by laser to treat the disease involving the anterior commissure.
