Wound dehiscence is a surgical complication in which the wound ruptures along the surgical suture with abdominal cavity bowel displacement. It is observed in 0.2-6% of operated patients. The extensive wound is a gateway for infection. Moreover, increased secretion of serous fluid induces a hygienic problem and may lead to secondary skin infections or bedsores. The negative pressure wound therapy (NPWT) system is an innovative therapeutic method. It perfectly executes the TIME strategy, receiving more and more recognition. The study presented a case of a 62-year old male patient after several consecutive wound dehiscence episodes who was primarily treated for rectal cancer by means of low anterior resection of the rectum. Due to acute respiratory insufficiency after several operations, wound necrosis with dehiscence was observed. Considering the high risk of perioperative death we abandoned surgical treatment and introduced conservative management using negative pressure wound therapy until the patient's health improved. Literature regarding the above-mentioned issue was also reviewed. [ABSTRACT FROM AUTHOR]

Accurate diagnosis of acute appendicitis (AA) is still a problem and is not always easy, even for experienced surgeons. Studies have shown that 20 to 30% of the appendices removedwere normal. Therefore, various scoring systems have been developed to aid in the diagnosis of doubtful cases and reduce the number of unnecessary appendectomies. The aim of this study was to assess the diagnostic value of different scoring systems in acute appendicitis. Material and methods. The study involved 94 patients who underwent laparotomy due to suspected acute appendicitis. Medical examination at hospital admission was performed by a resident and a general surgery specialist. The probability of AA was evaluated using six different scoring systems: Alvarado, Fenyo, Eskelinen, Ohman, Tzankis, and RIPASA. The resident calculated the results in individual systems. The decision to perform the operation was taken by a specialist surgeon who did not know the results. Results. Normal appendix was removed in 26% of cases. Eskelinen, RIPASA and Alvarado systems showed highest sensitivity (99%, 88% and 85%, respectively). Tzankis and Fenyo systems showed highest specificity (62% and 50%, respectively). Conclusions. Our study has shown limited value of scoring systems for the diagnosis of acute appendicitis. The systems may improve diagnostic accuracy as they require obtaining a more detailed medical history, and making a more thorough and organized data analysis. However, the scoring systems should be treated only as an aid to diagnosis [ABSTRACT FROM AUTHOR]
