Abstract Introduction Long-gap esophageal atresia represents a distinct entity among the esophageal atresia spectrum. In many patients, achieving a reasonable anastomosis depends on some millimeters of tissue. We aimed to determine what effect the suturing technique would have on esophageal ex vivo elongation as it may determine the strength of a primary anastomosis. Materials and Methods In an analysis of porcine esophagi from animals for slaughter (100–120 days old with a weight of 100–120 kg), we determined esophageal length gain of simple continuous and simple interrupted suture anastomoses subjected to linear traction until linear breaking strength was reached. Statistical power of 80% was ensured based on an a priori power analysis using five specimens per group in a separate exploratory experiment. Results The simple continuous suture anastomosis in 15 porcine esophagi (  = 4.47 cm, 95% confidence interval: 4.08–4.74 cm) outperformed the simple interrupted suture anastomosis in another 15 esophagi (  = 3.03 cm, 95% confidence interval: 2.59–3.43 cm) in length gain (Δ = 1.44 cm, 95% confidence interval: 0.87–2.01 cm, p < 0.0001). Conclusion Simple continuous anastomoses achieved higher length gain compared with simple interrupted suture anastomoses. This effect warrants an experimental assessment in vivo to assess its potential merits for clinical applicability.

<b><i>Background:</i></b> Anastomotic leak is regarded as one of the most feared complications of bowel surgery; avoiding leaks is a major priority. Attempts to reduce or eliminate leaks have included alternate anastomotic techniques. Human oral mucosa stem cells (hOMSC) are self-renewing and expandable cells derived from buccal mucosa. Studies have shown that hOMSC can accelerate tissue regeneration and wound healing. The objective of this study was to evaluate whether hOMSC can decrease anastomotic leak rates in a murine model of colon surgery. <b><i>Methods:</i></b> Two experiments were performed. In the first study, mice underwent colonic anastomosis using five interrupted sutures. hOMSC (<i>n</i> = 7) or normal saline (NS; <i>n</i> = 17) was injected into the colon wall at the site of the anastomosis. To evaluate whether hOMSC can impact anastomotic healing, the model was stressed by repeating the first experiment, reducing the number of sutures used for the construction of the anastomosis from five to four. Either hOMSC (<i>n</i> = 8) or NS (<i>n</i> = 20) was injected at the anastomosis. All mice that survived were sacrificed on postoperative day 7. Anastomotic leak rate, mortality, daily weight, and daily wellness scores were compared. <b><i>Results:</i></b> In the five-suture anastomosis, there were no differences in anastomotic leak rate, mortality, or daily weight. Mice that received hOMSC had significantly higher wellness scores on postoperative day 2 (<i>p</i> &#x3c; 0.05). In the four-suture anastomosis, there was a significant decrease in leak rate (70% [NS] vs. 25% [hOMSC], <i>p</i> = 0.029) and higher wellness scores in mice that received hOMSC (<i>p</i> &#x3c; 0.05). <b><i>Conclusion:</i></b> Our study suggests that injecting hOMSC at the colonic anastomosis can potentially reduce anastomotic leak and improve postoperative wellness in a murine model of colon surgery.

AbstractThe surgical education environment has been changing significantly due to restricted work hours, limited resources, and increasing public concern for safety and quality, leading to the evolution of simulation-based training in surgery. Of the various simulators, low-fidelity simulators are widely used to practice surgical skills such as sutures because they are portable, inexpensive, and easy to use without requiring complicated settings. However, since low-fidelity simulators do not offer any teaching information, trainees do self-practice with them, referring to textbooks or videos, which are insufficient to learn open surgical procedures. This study aimed to develop a new suture training system for open surgery that provides trainees with the three-dimensional information of exemplary procedures performed by experts and allows them to observe and imitate the procedures during self-practice. The proposed system consists of a motion capture system of surgical instruments and a three-dimensional replication system of captured procedures on the surgical field. Motion capture of surgical instruments was achieved inexpensively by using cylindrical augmented reality (AR) markers, and replication of captured procedures was realized by visualizing them three-dimensionally at the same position and orientation as captured, using an AR device. For subcuticular interrupted suture, it was confirmed that the proposed system enabled users to observe experts’ procedures from any angle and imitate them by manipulating the actual surgical instruments during self-practice. We expect that this training system will contribute to developing a novel surgical training method that enables trainees to learn surgical skills by themselves in the absence of experts.

Abstract: Female genital tract anomalies have important effects on reproductive function, and usually recognized after puberty. The membrane canalization process end to various hymenal forms. Microperforate hymen appears as a partial obstruction depending on its  size. Most often, patient will present with menstrual disorders, dyspareunia, and infertility. The aim of this research was to report a case of spontaneous pregnancy in postoperative microperforated hymen in form of case report. A 27-year-old woman, P0A0, complained of pain during intercouse. Patient had been married for 1,5 years, had reguler menstrual cycles without any contraceptive method, but not conceived yet. Inspection showed an obstructed vaginal introitus with a small opening laterally at 3 o’clock, consistent witn microperforate hymen. During surgery, short vaginal introitus was observed and no vaginal canal was seen. A sound was inserted through a small opening of 1 mm in diameter laterally at 3 o'clock, followed by sufficient incision and excision of the distal vaginal tissue. Interrupted suture of the proximal and distal mucosa was performed. The vaginal portion as well as uterus appeared normal. Postoperative tissue healing was good. A spontaneous pregnancy occurred 56 days after the surgery and a healthy term baby was born by caesarean section. In the case of microperforated hymen, menstrual flow can be normal. The patient complained of dyspareunia or impaired sexual penetration leading to infertility, although the presence of a small opening may allow passage of sperm and spontaneous pregnancy may occur before the surgery. Surgery can reduce psychological stress and improve reproductive function, allowing pregnancy to occur. Keywords:Abstract: Female genital tract anomalies have important effects on reproductive function, and usually recognized after puberty.
