Cesarean wound healing is influenced by surgeon experience, suture type, and technique. This study utilized a simulation model to quantify these effects. Obstetricians-gynecologists and junior residents performed two-layer continuous suturing on uterine models, forming eight groups based on experience level (expert, novice), suture type (conventional, barbed), and technique (Albert-Lembert, layer-to-layer). The ideal wound condition was defined as that achieved by an expert using barbed sutures and the layer-to-layer technique. Wound characteristics were quantified and compared to this ideal. Experts using barbed sutures in Albert-Lembert suturing showed higher wound density but greater deformation and larger endometrial openings (both P < 0.01). Novices using barbed sutures in Albert-Lembert suturing showed similar wound density but significantly greater deformation and opening (both P < 0.01). Novices using conventional sutures in layer-to-layer suturing showed the lowest wound density and longest suturing time (both P < 0.01). Notably, novices using barbed sutures achieved wound characteristics comparable to experts using conventional sutures in Albert-Lembert suturing and results closer to the ideal in layer-to-layer suturing. These findings establish a quantifiable standard for cesarean suturing and suggest that optimizing suture types and techniques may help compensate for differences in surgical expertise.

ABSTRACT

Aims/Introduction

Maternal hyperglycemia is associated with heavy for date (HFD) infants. Considering the association between body composition and hyperglycemia, we investigated the changes in maternal body composition and their relationship with HFD infants in pregnant women with diabetes.

Materials and Methods

Body composition was measured during pregnancy using a bioelectrical impedance analysis system. This retrospective study included 151 pregnant women; 27 women had type 1 diabetes mellitus (DM), 21 had type 2 DM, 101 were diagnosed with gestational DM, and 2 had overt DM. The number of HFD infants was 40.

Results

In the non‐type 1 DM group, change in fat mass (ΔFM) ( P  &lt; 0.01) and pre‐pregnancy BMI ( P  &lt; 0.05) were risk factors for HFD. In the insulin group, ΔFM, pre‐pregnancy BMI, and age (all P  &lt; 0.05) were risk factors for HFD. The area under the curve was 0.813 for the predictive model combined with ΔFM and pre‐pregnancy BMI in the non‐type 1 DM group and 0.818 for the model combined with ΔFM, pre‐pregnancy BMI, and age in the insulin group.

Conclusions

The combination of body composition parameters and clinical data may predict HFD in pregnant women with diabetes.

Abstract

Intramural pregnancy is a rare form of ectopic pregnancy, and the optimal treatment remains uncertain. We describe a 33‐year‐old woman (gravida 2, para 0) who visited our hospital with suspected ectopic pregnancy. The patient was asymptomatic and hemodynamically stable. Transvaginal ultrasonography revealed pregnancy at 6 weeks of gestation and a gestational sac and fetal heartbeat in the anterior muscular layer of the uterus, away from the endometrium. The fetal sac measured 26 mm. The serum human chorionic gonadotropin (hCG) level had increased to 27 655 mIU/mL. Accordingly, the patient was diagnosed with an intramural ectopic pregnancy and underwent total laparoscopic wedge resection using intraoperative ultrasonography. The postoperative course was uneventful, and she was discharged after 4 days. Her serum hCG level normalized at 26 days postoperatively. This case indicates that intraoperative laparoscopic ultrasonography seems viable for treating intramural pregnancies.
