One hundred and seventy-five patients with gastroesophageal reflux disease (GERD) were treated, 144 (82.2%) of them underwent surgery. In 106 (73.6%) patients laparotomy was used, in 38 (26.4%) -- laparoscopic surgeries. Transabdominal USE of the esophagus, stomach and duodenum, endoscopic ultrasonoraphy (EUS) of the esophagus were used for diagnosis of GERD in addition to standard tests. Based on EUS data, classification of severity of reflux-esophagitis was proposed. New method of laparoscopic creation of artificial lower esophageal sphincter (LES) with super thin (95, 45 mm) and super elastic filaments made of nikelid-titan alloy was developed in experiment and introduced into clinical practice. Thirty-four laparoscopic surgeries were performed, 26 (76.4%) of them -- with creation of artificial LES. In this group 94.4% of patients demonstrated excellent and good results in long-term period. Pressure in the area of LES in these patients increased by 70%, on the average, after surgery.

Torsion and ruptured ovarian cystadenocarcinoma with internal bleeding complicated with retroperitoneal hematoma after tumor transection: A case report.

Rationale: Ovarian tumor torsion is a critical gynecological emergency, predominantly affecting women of reproductive age, with benign teratomas being the most common culprits. In contrast, malignant ovarian tumors, such as mucinous cystadenocarcinoma, infrequently present with torsion due to their invasive and angiogenic characteristics. The occurrence of torsion in malignant tumors complicates diagnosis and management, particularly when associated with complications like congestion, infarction, and internal bleeding.

This prospective observational study aimed to compare abdominal hysterectomy (AH), vaginal hysterectomy (VH), and total laparoscopic hysterectomy (TLH) in terms of oxidative stress (OS) by measuring serum levels of total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI). Of the 3 groups, namely, AH, VH, and TLH, 22 patients were enrolled in each to investigate the aim of the study mentioned above. Patient demographics, clinical and surgical characteristics, and preoperative and postoperative (0th and 24th hours) serum TAS, TOS, and OSI levels were investigated.

In laparoscopy, the absence of ergonomics in the instruments affects the performance and efficiency of the surgeon, increasing the likelihood of developing musculoskeletal injuries. This article presents the development of a laparoscopic needle holder with an ergonomic handle and the experience in its use with surgeons in the intracorporeal suturing task. The handle of the laparoscopic needle holder consists of a semi-spherical piece that easily adapts to the palm of the surgeon's hand and improves the posture and ergonomics of the wrist, allowing the direct transmission of rotational movements around the longitudinal axis of the instrument towards the tip.

Background: Laparoscopy-assisted distal gastrectomy (LADG) with Billroth I (B-I) reconstruction is frequently performed for gastric cancer. However, the difference between the circular stapler technique (CS) and delta-shaped anastomosis (DA) remains unclear, especially regarding the postoperative endoscopic physiological findings.
Methods: Three hundred and one patients including 150 CS patients and 151 DA patients during LADG with B-I reconstruction between 2013 and 2019 at Saitama Medical University International Medical Center were chosen as study subjects.
Introduction: This study explored the effects of four different surgical methods in the treatment of cesarean scar pregnancy (CSP).
Methods: In this multicenter retrospective analysis of 359 patients, the surgical indices, the time taken for the serum human chorionic gonadotropin level to return to normal, the recovery time of menstruation, and the incidence of postoperative adverse reactions were comparatively analyzed. The clinical efficacies of various preoperative treatment methods to block the blood supply to CSP tissues and those of four different surgical methods to treat CSP, namely, curettage, hysteroscopic surgery, laparoscopic surgery, and vaginal surgery, were evaluated in this study.
