Abdominal Surgery

A prospective, randomized clinical study with a blinded evaluator to compare a post-surgical abdominal scar care protocol using Ozoaqua products versus standard care in patients undergoing open abdominal surgery. The primary objective is to assess whether the use of Ozoaqua, initiated in the immediate postoperative period according to wound evolution, improves abdominal scar quality at 3 months compared with usual care. The proposed design is an initial single-center study at the Clínica Universidad de Navarra, with 1:1 random allocation to two parallel arms: an intervention group receiving standard care plus Ozoaqua ozonated soap and oil, and a control group receiving standard care only. The primary scar assessment will be performed by a blinded evaluator, while treatment will be open-label due to the nature of the topical intervention. The target population consists of adult patients undergoing scheduled open abdominal surgery, with primary wound closure and an assessable linear abdominal scar. Follow-up will be integrated into routine clinical care, including an in-hospital phase during the first postoperative days and outpatient visits at approximately 2 weeks, 1 month and 3 months, with the latter being the main study visit. The primary endpoint will be scar quality at 3 months, assessed using the POSAS scale, particularly the blinded observer score. Secondary endpoints will include the patient POSAS score, scar evolution, wound complications, pain, pruritus, satisfaction, cutaneous adverse events, rescue treatments and adherence.

Postoperative pain after laparoscopic major upper abdominal surgery (e.g., gastric, hepatic, gallbladder, pancreatic surgery) is often severe, and inadequate analgesia may lead to increased opioid use, opioid dependence, and poor functional recovery. Current analgesic techniques such as neuraxial block have safety concerns (e.g., hypotension, neurological injury), while transversus abdominis plane (TAP) block is ineffective for blocking the lateral cutaneous branches of intercostal nerves in the upper abdomen. The External Oblique Intercostal Plane Block (EOIB) is a novel regional block technique that has shown promise in reducing postoperative opioids and pain in small-scale studies, but evidence for its use in major upper abdominal surgery is limited. This randomized controlled trial (RCT) aims to evaluate the analgesic efficacy and safety of bilateral EOIB combined with standard multimodal analgesia versus standard multimodal analgesia alone in patients undergoing elective laparoscopic major upper abdominal surgery. The primary outcome is the total postoperative opioid consumption (measured as Morphine Milligram Equivalents, MME) within 24 hours. Secondary and additional outcomes include pain scores (Verbal Rating Scale, VRS), recovery quality (QoR-15 scale), incidence of adverse events, and hospital stay.

Postoperative respiratory failure (PRF) is a dreaded complication that imposes a significant burden through unplanned admission to the ICU, post discharge disability and mortality. Despite widespread implementation of intraoperative lung-protective ventilation strategies over the past decade, results remain inconsistent. Interventions targeting individual parameters like tidal volume or positive end-expiratory pressure (PEEP) have shown equivocal results. The use of high PEEP and recruitment maneuvers raises safety concerns by possible negative hemodynamic effects. Recent studies suggest that individualizing ventilation strategies based on mechanical power-a composite parameter integrating tidal volume, plateau pressure, PEEP, and ventilator frequency-may better predict and help prevent PRF, independently of patients' baseline respiratory system compliance. These studies identified this parameter as interventional targets to reduce lung injury during mechanical ventilation. However, no multicenter randomized controlled trial has been performed in the field of ventilatory settings titration during invasive mechanical ventilation in operating room. The investigators hypothesize that a ventilation strategy aimed at decreasing mechanical power will reduce the incidence of PRF and mortality in patients undergoing abdominal surgery, compared with a standard strategy using fixed tidal volume and PEEP

Major abdominal surgery often leads to significant postoperative pain, anxiety, and prolonged hospital stays, which can delay overall recovery. This study aims to evaluate the effectiveness of immersive Virtual Reality (VR) as a non-pharmacological intervention to enhance the quality of recovery and reduce the length of hospital stay. Patients in the intervention group will engage in standardized VR sessions featuring guided relaxation and mindfulness-based stress reduction, starting from the evening before surgery through the third postoperative day. The study compares this VR-enhanced protocol against standard perioperative care within an Enhanced Recovery After Surgery (ERAS) framework. The findings are expected to determine if VR can serve as a feasible and effective tool to improve clinical outcomes and patient well-being in surgical wards.

This is a bicentric, prospective, non-pharmacological, randomized study designed to compare the efficacy and safety of awake neuraxial anesthesia with sedation versus general anesthesia in frail patients undergoing elective major laparoscopic or robotic abdominopelvic surgery. A total of 100 frail patients aged over 60 years, with ASA physical status \>2 and evidence of frailty and/or cognitive vulnerability, will be randomized to receive either standard general anesthesia with mechanical ventilation or thoracic neuraxial anesthesia combined with non-GABAergic sedation while maintaining spontaneous breathing. The primary objective is to evaluate the feasibility in terms of recruitment of a RCT conducted in a population of frail or cognitively impaired patients undergoing major laparoscopic abdominal surgery, randomized to a neuraxial or general anesthetic approach in which the effects on the onset of postoperative delirium and postoperative cognitive dysfunction (POCD) will be determined. Secondary outcomes include the occurrence of postoperative organ dysfunction (respiratory, cardiovascular, renal, and metabolic), length of hospital stay, time to recovery after surgery, and postoperative mortality. Patients will undergo comprehensive perioperative clinical, laboratory, and ultrasound assessments, including lung and renal ultrasound evaluations. Neurological and functional status will be assessed during hospitalization, at 1 month, and via telephone follow-up at 1 year after surgery. The aim of the study is to evaluate the feasibility and safety of performing two different anesthetic techniques on fragile patients.

Recent research suggests a significant link between gut microbiota and anastomotic leakage (AL) in colorectal surgery. Patients who develop AL have a higher abundance of bacteria from the Lachnospiraceae family and lower microbial diversity. Considering the bibliographic data, our main interest is to analyze the microbial population of patients in our social environment and then look for differences in the microbiome between those who have suffered an anastomotic dehiscence (around 8-9% according to the results of our hospital's Surgery Department) and those who have not.

The aim of the planned study is the development of surgical assistance functions on the basis of clinical routine data and the evaluation of the technical feasibility of an intraoperative demonstration and visualization of such assistance functions in visceral surgery. Furthermore, this trial aims to provide preliminary data on the clinical outcome of such assistance systems.

This randomized controlled study aims to evaluate the effect of preoperative abdominal superficial effleurage training on the development of postoperative constipation in patients undergoing abdominal surgery. Participants will be randomly assigned to an intervention group receiving abdominal superficial effleurage training in addition to routine care or to a control group receiving routine care only. The effleurage technique will be taught preoperatively and performed by patients postoperatively. Postoperative constipation will be assessed on the 10th postoperative day using the Bristol Stool Form Scale. The findings of this study are expected to contribute to non-pharmacological nursing interventions for the prevention of postoperative constipation.

This randomized controlled trial aims to compare the outcomes of Polyglactin (Vicryl) versus Polypropylene (Prolene) sutures for rectus sheath closure in patients undergoing midline laparotomy. The study will evaluate the rates of incisional hernia, surgical site infection (SSI), wound dehiscence, chronic pain, and suture sinus formation. Participants aged 18-70 years, undergoing either elective or emergency laparotomy, will be randomly assigned to receive either Polyglactin or Polypropylene sutures. The primary outcome measure is the incidence of incisional hernia at 6 months, with secondary outcomes including SSI, wound complications, and chronic pain. The study is particularly important in the context of Pakistan, where such comparative data is limited, and aims to provide evidence-based recommendations for optimal suture material selection in general surgery.

Pip Care is developing a personalized, interactive surgical journey platform with a live health coach that works directly with health systems to optimize the perioperative care process. Our Health Insurance Portability and Accountability Act (HIPAA)-compliant platform, Pip, can be integrated into any electronic medical record (EMR), thus alleviating the administrative burden by making operational workflows more efficient. The PIP empowers patients and their families to be more involved in their care by breaking down a patient's healthcare plan into definable, easy-to-understand, and easy-to-complete tasks. Additionally, a health coach completes a health intake to create a personalized perioperative care plan, meets regularly with the patient to encourage goal accomplishment, and facilitates care coordination. This project has 2 phases; Phase I is to assess usability of the Pip Care platform in surgical patients, Phase II is a RCT (Randomized Controlled Trial) to assess surgical clinical outcomes while using Pip compared to standard of care.

The aim of the study is to evaluate the effect of a new care strategy, including earlier and more intensive mobilization and individually adapted breathing exercises, regarding length of stay, recovery, complications and which factors predict interventions early in the postoperative course after various abdominal surgical procedures.

According to the statistical data of the Ministry of Health for the year 2021 in Türkiye, approximately 4.7 million surgical interventions are performed annually. According to the 2017 data from the National Health Service-Associated Infections Surveillance Network, the Surgical Site Infection (SSI) rate in our country is 0.72%, and it is stated that it can be prevented by approximately 60%. Dressing application holds an important place in surgical wound management, wound healing, and preventing complications. Patients may experience pain, anxiety, and fear due to unknown factors and previous experiences during the dressing change which holds an important place in wound care management. The aim is to minimize patients\' negative emotions/situations during dressing changes by diverting their attention elsewhere using virtual reality (VR) glasses and stress balls. Upon reviewing the literature, no study was found that examines the effect of applying VR glasses and stress balls during abdominal surgery dressing changes on pain, vital signs, anxiety, fear, comfort, and satisfaction levels in adults. In this regard, the aim of the research is; to examine the effects of VR glasses and stress ball application on pain, vital signs, anxiety, fear, comfort, and satisfaction levels during dressing changes in patients undergoing abdominal surgery. The study was designed as a pre-test post-test control group randomized experimental model. The sample of the study consists of adult patients who underwent abdominal surgery in Isparta City Hospital General Surgery Service-1. In the study sample, 120 individuals were included in total 40 with VR glasses, 40 individuals using stress balls, and 40 in the control group. Patient Information Form, Visual Analog Scale, and State-Trait Anxiety Scale will be used in data collection. Data from the study will be analyzed with number, percent, average, x-square, variance, and t-test in a computer environment. In consideration of the data, it is believed that important findings will be obtained in increasing satisfaction and comfort by eliminating pain, anxiety, and fear during dressing changes in patients.

A postoperative pulmonary complication (PPC) is the most common serious complication after Abdominal surgery under GA which lead to longer hospital stays and have deleterious outcomes on lung volumes, mucociliary clearance, accumulation of mucus, saliva and cough reflex. Chest physiotherapy for airway clearance which includes postural drainage, chest percussion, vibrations, Along with these, breathing exercises such ACBT and Blow bottle technique are recommended to clear secretion which aid in enhancing pulmonary function by effectively mobilizing and eliminating excess bronchial secretions. This study of randomized clinical trial will check the comparative effect of ACBT and Blow Bottle Technique in patients with abdominal surgeries under GA by taking a sample of 44 patients through non probability convenience sampling technique. Subject of both gender will be included between the age of 30 to 50 years who will undergoes with elective abdominal surgeries under GA (Cholecystectomy, Hysterectomy ,Appendectomy, Hemorrhoidectomy) and Laparoscopic /open. Elective surgeries under spinal anesthesia, emergency surgeries, cardiothoracic surgeries and hemodynamically unstable subjects will be excluded. 22 subjects will receive ACBT and other 22 subjects will receive Blow bottle technique for 20 minutes duration per session, two sessions per day for a period of 5 days. The status of airway clearance, oxygen saturation and lungs volumes will be measured pre and post intervention on day 1 and at the end of 5th day by using BCSS, Pulse oximeter and Spirometer.
