Enteric fistulas are a common problem in gastrointestinal tract surgery and remain associated with significant mortality rates, due to complications such as sepsis, malnutrition, and electrolyte imbalance. The increasingly widespread use of open abdomen techniques for the initial treatment of abdominal sepsis and trauma has led to the observation of so-called entero-atmospheric fistulas. Because of their clinical complexity, the proper management of enteric fistula requires a multidisciplinary team. The main goal of the treatment is the closure of enteric fistula, but also mortality reduction and improvement of patients’ quality of life are fundamental. Successful management of patients with enteric fistula requires the establishment of controlled drainage, management of sepsis, prevention of fluid and electrolyte depletion, protection of the skin, and provision of adequate nutrition. Many of these fistulas will heal spontaneously within 4 to 6 weeks of conservative management. If closure is not accomplished after this time point, surgery is indicated. Despite advances in perioperative care and nutritional support, the mortality remains in the range of 15 to 30%. In more recent years, the use of negative pressure wound therapy for the resolution of enteric fistulas improved the outcomes, so patients can be successfully treated with a non-operative approach. In this review, our intent is to highlight the most important aspects of negative pressure wound therapy in the treatment of patients with enterocutaneous or entero-atmospheric fistulas.

Gastrosplenic fistula (GSF) is an unusual event that might occur in patients with various gastric or splenic diseases. While GSF related to gastric and splenic malignancies is well-documented in the literature, cases of GSF due to a splenic abscess are extremely rare. We experienced the case of a 49-year-old man with a medical history of tricuspid cardiac valve replacement for infective endocarditis who presented with a sudden onset of anemia and melena. With the assistance of imaging and endoscopy, a primary splenic abscess complicated by spontaneous GSF was diagnosed. A prompt splenectomy with partial gastrectomy was performed. GSF is a serious occurrence associated with a high risk of morbidity and mortality. The early recognition of GSF related to a splenic abscess is crucial to prevent major complications. Surgical resection with splenectomy and partial gastrectomy is frequently preferred for the treatment of large abscesses with GSF.

Background and Objectives: Acute appendicitis is a common surgical emergency, and while appendectomy typically results in good outcomes, post-operative complications, like intra-abdominal abscesses, can occur. Traditional biomarkers, such as white blood cells count and C-reactive protein, often lack the accuracy needed for early detection. Procalcitonin is emerging as a potential marker for predicting post-operative infections. This pilot study evaluates the role of kinetics of procalcitonin, measured via point-of-care testing, in predicting abscess formation in patients with non-complicated appendicitis. Materials and Methods: The study involved 33 patients undergoing appendectomy for non-complicated acute appendicitis. The levels of procalcitonin were measured at four time points: pre-operatively (T0), post-operatively (T1), on the first post-operative day (T2), and at discharge (T3). The primary outcome was the development of post-operative abscesses, confirmed by imaging or intervention. Results: Four patients (12%) developed abscesses. The levels of procalcitonin were significantly higher in the abscess group at all time points compared to the non-abscess group (p < 0.05). The levels of procalcitonin in the abscess group plateaued after an initial post-operative decline, while levels steadily decreased in the non-abscess group. Conclusions: Procalcitonin, particularly its kinetic profile, may serve as a valuable early marker for predicting post-operative abscess formation. Point-of-care testing for procalcitonin can enable timely intervention, improving outcomes. Kinetics of procalcitonin show promise as a predictor for post-operative abscesses after appendectomy, though larger studies are needed to confirm these findings.
