OBJECTIVE: To explore the suitability of conservative management for neonatal ovarian cysts in newborns. METHODS: A retrospective cohort study was conducted, involving infants diagnosed with neonatal abdominal/pelvic cysts at two separate medical institutions from January 2015 through July 2021. Data collection included clinical characteristics, imaging results, pathological findings, and postnatal outcomes. Statistical analyses were performed using the Student's t-test, Mann-Whitney U-test, and receiver operating characteristic (ROC) curve...

BACKGROUND: To determine whether frailty can predict prolonged postoperative ileus (PPOI) in older abdominal surgical patients; and to compare predictive ability of the FRAIL scale, the five-point modified frailty index (mFI-5) and Groningen Frailty Indicator (GFI) for PPOI. METHODS: Patients (aged ≥ 65 years) undergoing major abdominal surgery at our institution between April 2022 to January 2023 were prospectively enrolled. Frailty was evaluated with FRAIL, mFI-5 and GFI before operation...

Uterine leiomyosarcoma is a rare malignant gynecologic tumor that arises from the myometrial or endometrial stromal precursor cells. This tumor has the highest prevalence in the pre- and post-is more frequent between 40 and 60 years old. It has a very unfavorable prognosis: only early-stage tumors have an acceptable prognosis; unfortunately, it is often diagnosed accidentally, typically on an advanced stage, when hematological metastases have already spread. Surgery is the main treatment strategy, while systemic treatment and radiotherapy are not recommended due to the lack of results...

AIM: Acquired post-transplant diaphragmatic hernia (PTDH) is a rare complication of liver transplantation (LT) in children. We aimed to present our experience in PTDH, and a possible causative background is discussed. METHODS: Medical records of patients who had undergone diaphragmatic repair following LT between 2015 and 2023 were reviewed. Demographic information, details of primary diseases necessitating LT, transplantation techniques, and clinical findings associated with PTDH were evaluated...

BACKGROUND: Pulmonary function is impaired after major abdominal surgery and might be less impaired by restrictive fluid administration. Under the assumption of a fluid-sparing effect of colloids, we tested the hypothesis that an intraoperative colloid-based goal-directed fluid management strategy impairs postoperative pulmonary function parameters less compared to goal-directed crystalloid administration. METHODS: We performed a preplanned, single-center substudy within a recently published trial evaluating the effect of goal-directed crystalloids versus colloids on a composite of major complications...

BACKGROUND: The majority of small bowel obstructions (SBO) are caused by adhesion due to abdominal surgery. Internal hernias, a very rare cause of SBO, can arise from exposed blood vessels and nerves during pelvic lymphadenectomy (PL). In this report, we present two cases of SBO following laparoscopic and robot-assisted lateral lymph node dissection (LLND) for rectal cancer, one case each, of which obstructions were attributed to the exposure of blood vessels and nerves during the procedures...

BACKGROUND: Complete mesocolic excision (CME) and central vascular detachment are very important procedures in surgery for colorectal cancer. Preoperative and intraoperative assessments of the anatomy of major colorectal vessels are necessary to avoid massive bleeding, especially in endoscopic surgery. A case with a rare anomaly in which the middle colic artery (MCA) and ileocolic artery (ICA) had a common trunk is reported. CASE PRESENTATION: The patient was a 73-year-old woman diagnosed with ascending colon cancer on colonoscopy...

BACKGROUND: Visceral pain induced by pancreatic cancer seriously affects patients' quality of life, and there is no effective treatment, because the mechanism of its neural circuit is unknown. Therefore, the aim of this study is to explore the main neural circuit mechanism regulating visceral pain induced by pancreatic cancer in mice. METHODS: The mouse model of pancreatic cancer visceral pain was established on C57BL/6N mice by pancreatic injection of mPAKPC-luc cells...

BACKGROUND: In pancreatic ductal adenocarcinoma (PDAC), invasion of connective tissues surrounding major arteries is a crucial prognostic factor after radical resection. However, why the connective tissues invasion is associated with poor prognosis is not well understood. MATERIALS AND METHODS: From 2018 to 2020, 25 patients receiving radical surgery for PDAC in our institute were enrolled. HyperEye Medical System (HEMS) was used to examine lymphatic flow from the connective tissues surrounding SMA and SpA and which lymph nodes ICG accumulated in was examined...

OBJECTIVES: Paraplegia remains one of the major complications of contemporary open thoracoabdominal aortic aneurysm (TAAA) repair. Intraoperative motor-evoked potentials (MEPs) act as a surrogate measure for spinal cord homeostasis. The purpose of this study was to evaluate the results of intraoperative neuromonitoring in contemporary TAAA repair and its association with postoperative spinal cord ischemia. METHODS: Patients who underwent open type 2 or 3 TAAA or completion aortic repair utilizing intraoperative neuromonitoring were identified between May 2006 and November 2023...

INTRODUCTION: Endovascular aortic repair (EVAR) was originally designed as a treatment modality for patients with abdominal aortic aneurysms (AAAs) deemed unfit for open repair. However, the definition of "unfit for open repair" is largely subjective and heterogenous. The purpose of this study was to compare patients deemed unfit for open repair who underwent EVAR to a matched cohort who underwent open repair for infrarenal AAAs. METHODS: The Vascular Quality Initiative (VQI) of the Society for Vascular Surgery (SVS) was queried for patients who underwent EVAR and open infrarenal AAA repair from 2003-2022...

Objectives: Intra-abdominal testes are located in a variety of intra-abdominal positions, most less than 2 cm from the internal ring. Various surgical techniques of laparoscopic orchiopexy have been described to date. The aim of this study was to evaluate the safety and long-term efficacy of a single-stage, vessel-preserving, laparoscopic orchiopexy for intra-abdominal testes in pediatric patients. Methods: A retrospective search of the medical records of 32 children (34 testes) who underwent single-stage, vessel preserving, laparoscopic orchiopexy for intra-abdominal testes between 1 January 2014 and 31 December 2023 was performed...

BACKGROUND: Anaemia following major surgery may be associated with unplanned readmission to hospital. However, the severity-response relationship between the degree of anaemia at discharge and the risk of unplanned readmission is poorly defined. We aimed to describe the severity-response relationship between haemoglobin concentration at the time of discharge and the risk of unplanned readmission in a cohort of patients undergoing different types of major surgery. METHODS: We performed a retrospective cohort study in a single tertiary health service, including all patients who underwent major surgery (orthopaedic, abdominal, cardiac or thoracic) between 1 May 2011 and 1 February 2022...

BACKGROUND: Hospital volume is associated with mortality after open aortic aneurysm repair. Fenestrated and branched endovascular aortic repair (B-FEVAR) has been increasingly used for repair of complex thoracoabdominal and juxtarenal aneurysms but evidence of a center-volume relationship is limited. We aimed to measure the association of center volume with in-hospital mortality, post-operative outcomes and 1-year survival following B-FEVAR. METHODS: Patients undergoing elective endovascular thoracoabdominal and complex abdominal aneurysm repair with branch intervention (2014-2021) listed within the national Vascular Quality Initiative Thoracic Endovascular Aortic Repair (TEVAR)/complex EVAR database were analyzed...

INTRODUCTION: Vascularized Composite Allografts (VCA) are usually performed in a full major histocompatibility complex mismatch setting, with a risk of acute rejection depending on factors such as the type of immunosuppression therapy and the quality of graft preservation. In this systematic review, we present the different immunosuppression protocols used in VCA and point out relationships between acute rejection rates and possible factors that might influence it. METHODS: This systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines...

Impalement injuries are rare and complex problems, often involving multiple organ injuries. An 18-year-old male was admitted to our emergency department after a car accident. Positioned in the right-side recumbent position, he had a 4.5 cm diameter pipe penetrating from his left abdomen to his back. Given the pipe's length exceeding the CT gantry's capacity, further imaging tests were not feasible. Consequently, the patient proceeded directly to the operating room without preoperative imaging. Before laparotomy, a left thoracotomy was conducted for aortic cross-clamping, anticipating uncontrollable bleeding during pipe removal...

STUDY OBJECTIVE: Following robot assisted abdominal surgery, the pain can be moderate in severity. Neuraxial analgesia may decrease the activity of the detrusor muscle, reduce the incidence of bladder spasm and provide effective somatic and visceral analgesia. In this systematic review, we assessed the role of neuraxial analgesia in robot assisted abdominal surgery. DESIGN: Systematic review. SETTINGS: Robot assisted abdominal surgery. PATIENTS: Adults...

AIM: This study aimed to evaluate the effects of Fried Frailty Phenotype Questionnaire (FFPQ) scores on patient-reported postoperative outcomes. METHODS: This secondary analysis of a prospective observational study included 230 inpatients aged ≥65 years undergoing elective abdominal cancer surgery. The primary outcome was the Quality of Recovery-15 score on postoperative days 2, 4 and 7. The secondary outcomes included disability-free survival, defined as a 12-item World Health Organization Disability Assessment Schedule 2...

BACKGROUND: Small-diameter vascular grafts have become the focus of attention in tissue engineering. Thrombosis and aneurysmal dilatation are the two major complications of the loss of vascular access after surgery. Therefore, we focused on fabricating 3D printed electrospun vascular grafts loaded with tetramethylpyrazine (TMP) to overcome these limitations. METHODS: Based on electrospinning and 3D printing, 3D-printed electrospun vascular grafts loaded with TMP were fabricated...

BACKGROUND: The application of resuscitative endovascular balloon occlusion of the aorta (REBOA) in trauma resuscitation, including for profound shock and cardiac arrest, has gained prominence. This study aimed to determine the characteristics of patients who were transported to the trauma resuscitation area (the TTRA group) and those who died at the scene (the DAS group), aiming to identify suitable REBOA candidates and critical contraindications. METHODS: A descriptive research design was used...
