The importance of rectal contrast in CT assessment to detect anastomotic leakage after colorectal surgery.

AIM: Computed tomography (CT) is currently the diagnostic tool most often used to detect anastomotic leakage (AL) after colorectal surgery. The aim of this study was to investigate the value of rectal contrast. METHOD: All patients who underwent colorectal surgery with a primary anastomosis between 2009 and 2018 were identified from a prospectively maintained database. Patients who underwent postoperative CT scanning in suspicion of AL were included. The clinical and radiological outcomes of patients with and without rectal contrast were compared. RESULTS: A total of 1183 patient records were reviewed; 225 patients underwent CT-abdomen in suspicion of AL. Of these patients, 175 (77.8%) received rectal contrast. Sensitivity and specificity in this group were 78% and 94%, respectively. The positive predictive value (PPV) was 0.78 and the negative predictive value (NPV) was 0.94. In the group without rectal contrast (n = 50), sensitivity was 47%, specificity 88%, PPV 0.66 and NPV 0.76. In patients who received rectal contrast, contrast reached the anastomosis in 81.7% compared with 26.0% in patients who were given only oral contrast (p < 0.001). The sensitivity increased to 93% in the group of patients with contrast at the anastomosis, the specificity to 97%, the PPV to 0.88 and the NPV to 0.98. No adverse events were observed after the use of rectal contrast. CONCLUSION: The use of rectal contrast led to a significant increase in the predictive value of CT scanning for AL, especially when it reached the anastomosis. This suggests that rectal contrast is a safe and useful adjunct to CT-abdomen in the detection of AL.

Complications and Functional Outcome Following Operative Treatment of Talus Neck and Body Fractures: A Systematic Review.

Background: Central talar fractures are rare and often associated with impaired functional outcome. Despite recent advances in diagnosis and management of talus fractures, complications rates remain high and functional outcome is generally poor. This study aims to provide an overview of complication rates and functional outcome following operative treatment of talar neck and body fractures. This may help in clinical decision making by improving patients' expectation management and tailored treatment strategies. Methods: A systematic review of the literature was conducted of studies published from January 2000 to July 2021 reporting functional outcome and/or complications following operative treatment of talar neck, body, or combined neck and body fractures. Keywords used were (Talar fracture) or (Talus fracture). Data on complication rates and functional outcome was extracted from selected articles. Results: A total of 28 articles were included in our analysis reporting 1086 operative treated talar fractures (755 neck [70%], 227 body fractures [21%], and 104 combined body and neck fractures [9%]). The mean follow-up was 48 (range 4-192) months. Complications occurred frequently with; 6% surgical site infection, 8% nonunion, 29% avascular necrosis, 64% osteoarthritis, and in 16% a secondary arthrodesis was necessary. A wide variety in functional outcome was reported; however, there seems to be a correlation between fracture classification and postoperative complications. Conclusion: Operative treatment of central talar fractures is associated with a high incidence of early and late complications and often leads to an impaired functional outcome. Standardization of talar fracture classification and scoring systems in combination with large sample-sized prospective studies are warranted to detect further predictive factors influencing tailormade treatment strategies and patient expectation management. Level of Evidence: Level III, Systematic review of case series and case-control studies.

Fractures of the Cuboid Bone: A Critical Analysis Review.

Cuboid fractures rarely occur in isolation, and a high index of suspicion for the presence of Chopart, Lisfranc, or complex midfoot injuries should be raised. The cuboid is the cornerstone of the lateral column and acts as a bridge between the lateral column and the transverse plantar arch. Its most important role is maintenance of lateral column length and associated motion in the midtarsal and tarsometatarsal joints. To date, a classification system that is validated for clinical practice (i.e., guidance for management and prediction of outcome and prognosis) is lacking. The principles of operative treatment are restoration of articular congruity, lateral column length, and stability of the Chopart and Lisfranc joints. Nonoperative management is reserved for nondisplaced articular fractures (<1 mm) or avulsion fractures that are caused by low-energy trauma.

Functional Outcome and Quality of Life After Nonoperative Treatment of Posterior Process Fractures of the Talus.

BACKGROUND: Fractures of the posterior process of the talus are frequently overlooked, possibly leading to nonunion, arthritis, and chronic pain. Given the rare occurrence, previous case series have been small and without functional outcome scores. Therefore, we aimed to provide evidence on outcomes after nonoperative and operative management of posterior process fractures of the talus. METHODS: All patients treated at a level 1 trauma center between 2012 and 2018 were retrospectively evaluated. Patient, fracture, and treatment characteristics were collected, and functional outcome as well as quality of life were assessed. Twenty-nine patients with posterior process fractures of the talus were identified in our database. RESULTS: The most frequently seen mechanism of trauma was fall from height in 13 patients (44.8%). Twenty-two patients underwent primary arthrodesis or operative reduction and fixation of the fracture (75.9%). Eighty-two percent of the patients returned the questionnaires with a mean follow-up of 6 years. The 2 patients with primary arthrodesis were excluded from outcome analysis. The mean Foot Function Index score was 1.8 (range 0.0-10). The mean American Orthopaedic Foot & Ankle Society (AOFAS) score was 78.7 points (range 0-100). The mean quality of life EuroQol-5D (EQ-5D) index score was 0.78 (range -0.26 to 1). The mean visual analog scale (VAS) on overall patient satisfaction was 8.2 (range 1-10). CONCLUSION: Operative management of extended posterior talar fractures was found to provide good functional outcome, quality of life, and patient satisfaction. Although the patients treated nonoperatively were found to have less severe injuries, they demonstrated worse overall outcome, which is supportive of surgical management. Nonoperative treatment is therefore only justified in selected patients. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Gastrointestinal histoplasmosis mimicking peritonitis carcinomatosis: a rare case of an emergent surgical presentation of HIV de novo.

Gastrointestinal perforation due to infection, including disseminated histoplasmosis, is a rare cause of the surgical acute abdomen, especially in an apparently healthy patient. We describe a rare case of gastrointestinal histoplasmosis-induced small intestine perforation as the first manifestation of acquired immune deficiency syndrome in a healthy patient. Remarkably, the disease mimicked peritonitis carcinomatosis during explorative laparoscopy.
