AI Article Synopsis

  • The study aimed to determine if preserving the cervix during hysterectomy can help prevent vaginal vault prolapse later on.
  • The research involved performing supracervical hysterectomies on 12 unembalmed cadavers while measuring how far the cervical stump moved under different weights.
  • Results indicated that both total and supracervical hysterectomy showed similar resistance to pressure applied to the vaginal apex, suggesting that cervical preservation may not significantly impact the risk of prolapse.

Article Abstract

Objective: The objective of the study was to assess whether cervical preservation at the time of hysterectomy may help prevent subsequent apical vaginal vault prolapse.

Study Design: Supracervical hysterectomies were performed in 12 unembalmed cadavers. Successive hanging weights of 1, 2, 3, and 4 kg were loaded against the cervical stump and distances moved were recorded. The same process was repeated after completion of a total hysterectomy.

Results: Average distances pulled with 1, 2, 3, and 4 kg of traction against the cervical stump were 17.8 +/- 1.9, 24.1 +/- 2.5, 29.0 +/- 2.8, and 34.3 +/- 3.5 mm, respectively. After total hysterectomy, these distances were 17.5 +/- 2.5, 23.5 +/- 2.6, 29.3 +/- 3.1, and 34.5 +/- 3.6 mm, respectively.

Conclusion: In unembalmed cadavers, it appears that total abdominal hysterectomy and supracervical hysterectomy provide equal resistance to forces applied to the vaginal apex.

Article Synopsis
  • The study compares total laparoscopic hysterectomy (TLH) and laparoscopic supracervical hysterectomy (LSCH) during minimally invasive sacrocolpopexy for treating uterovaginal prolapse.
  • Results showed no significant difference in overall recurrence of prolapse between the two methods, but TLH had lower odds of recurrence in multivariable analysis.
  • TLH had a higher proportion of mesh exposures with lightweight mesh, but this finding wasn't significant after adjusting for other factors.

Objectives: Failures and complications associated with treatments comprising laparoscopic sacrohysteropexy (SHP) for advanced pelvic organ prolapse (POP) are unclear. We compared failure rates associated with SHP and laparoscopic supracervical hysterectomy (SCH)/sacrocolpopexy (SCP) for advanced POP to determine whether they differed.

Methods: Clinical data of patients who underwent SHP (n = 52) and SCH/SCP (n = 209) were retrospectively examined.

  • Uterine leiomyomas can sometimes lead to serious conditions like deep vein thrombosis (DVT) and pulmonary embolism (PE), even in patients with no known risk factors.
  • A 38-year-old woman experienced leg swelling, pain, and breathing difficulties and was diagnosed with DVT and PE, which were confirmed through imaging.
  • The treatment involved mechanical thrombectomy and hysterectomy, resulting in a full recovery with no recurrence of thromboembolic events after 11 months.

Placenta percreta, a rare variant of placenta accreta spectrum (PAS) disorders, poses a significant risk of life-threatening hemorrhage associated with the adherent placenta. Bladder involvement signifies an even rarer incidence and may sometimes present solely with gross hematuria. Therefore, it is imperative to consider both microscopic and gross hematuria during pregnancy as alarming signs.

We report the sudden onset of dyspnea and loss of consciousness and fetal bradycardia in a middle-aged obese nulliparous woman at 39 weeks of gestation during first stage of labor leading to the decision for emergency cesarean section. Still during surgery, the mother underwent cardiac arrest. Transesophageal echocardiography during resuscitation showed right ventricular failure leading to the diagnosis of pulmonary embolism.
