Aim: To verify the expected benefit on usage of IHSI (intra-operative hypertonic saline irrigation) in aspect of decreasing subcutaneous fluid secretion and decreased hospital stay in patients undergoing various abdominal wall reconstruction procedures.

Recommendations for modern perioperative care for elective surgery: consensus of panel of exerts.

Introduction: Correct surgical technique and perioperative care are two factors that can reduce the number of complications, improve treatment outcomes and shorten the length of hospital stay. The introduction of enhanced recovery protocols has changed the approach to patient care in some centers. However, there are significant differences among centers, and in some the standard of care has remained unchanged.

The Legal nature of guidelines of scientific societies in the light of the Polish legal system.

Introduction: The paper aims to establish the legal nature of the guidelines in the Polish legal system and the possible formal consequences of introducing such guidelines (litigation, professional responsibility) as well as practical implications concerning the method of treating patients.

Methods: Analysis is clarifying fundamental issues that largely determine the content of the study. The basic assumption is to analyze the legal nature of the prepared guidelines from the point of view of public law, i.

Is mesh fixation necessary in laparoendoscopic techniques for M3 inguinal defects? An experimental study.

Background: Although international guidelines recommend not fixing the mesh in almost all cases of laparoendoscopic repairs, in case of large direct hernias (M3) mesh fixation is recommended to reduce recurrence risk. Despite lack of high-quality evidence, the recommendation was upgraded to strong by expert panel. The authors conducted a research experiment to verify the hypothesis that it is possible to preserve the mesh in the operating field in large direct hernias (M3) without the need to use fixing materials.

Post-partum abdominal wall insufficiency syndrome (PPAWIS): lessons learned from a single surgeon's experience based on 200 cases.

Background: Post-partum abdominal wall insufficiency (PPAWI) with rectus diastasis is present in over 30% of women after pregnancy. Little is known about how PPAWI affects the social, sexual life and self-esteem of patients. This study was designed to evaluate the safety of onlay mesh combined with abdominoplasty and its impact on the well-being of the patients.

In vivo performance of intraperitoneal onlay mesh after ventral hernia repair.

Background: Ventral hernia repair needs to be improved since recurrence, postoperative pain and other complications are still reported in many patients. The behavior of implants in vivo is not sufficiently understood to design a surgical mesh mechanically compatible with the human abdominal wall.

Methods: This analysis was based on radiological pictures of patients who underwent laparoscopic ventral hernia repair.

Minimally invasive techniques and indocyanine angiography in anterior abdominal wall reconstruction after multiple laparotomies.

Anterior abdominal wall reconstruction surgery in patients who have undergone multiple laparotomies is associated with a high risk of complications. For this reason, minimally invasive surgery techniques are used to avoid abdominal compartment syndrome, to enhance wound healing and to reduce postoperative pain and blood loss. This paper presents a case of a patient who was admitted to the Department of General Surgery in Puck Hospital as a result of extensive anterior abdominal wall deformation with an end descending colostomy.

Do we need changes in the organization of training in the hernia treatment in Poland? A survey on the acknowledgment of the recommendations of international hernia societies by surgeons.

In the therapy of an inguinal hernia, there is a huge variety in the way of treating and the choice of surgical technique. Practice shows that the intraoperative improvisation and surgeons' own modifications of the original techniques have become part of routine procedure.
