Methods: A total of 116 patients with acute suppurative appendicitis were enrolled in this study. The collection period was from December 2021 to December 2023. The patients were randomly grouped into a control group (surgical treatment) and an observation group (surgical treatment and postoperative anti-infection treatment), of 58 patients each. At the end of the treatment, the results of each index of the two groups were compared. Results: The length of hospitalization time, exhaust time, and incidence of complications in the observation group were shorter than those of the control group (P < 0.05). The total effective rate of the observation group was higher than that of the control group (P < 0.05). Conclusion: It is crucial to perform anti-infective treatment promptly after surgical treatment in patients with acute suppurative appendicitis. It can effectively prevent the occurrence of complications and improve the clinical efficacy. Hence, it is worthy of research and promotion.展开更多

However, inflammatory neutrophils, recruited to the postoperative tumor site, have been shown to exacerbate tumor regeneration and limit the efficacy of cancer vaccines. Consequently, addressing postoperative immunosuppression caused by neutrophils is crucial for improving treatment outcomes. This study presents a combined chemoimmunotherapeutic strategy that employs a biocompatible macroporous scaffold-based cancer vaccine (S-CV) and a sialic acid (SA)-modified, doxorubicin (DOX)-loaded liposomal platform (DOX@SAL). The S-CV contains whole tumor lysates as antigens and imiquimod (R837, Toll-like receptor 7 activator)-loaded PLGA nanoparticles as immune adjuvants for cancer, which enhance dendritic cell activation and cytotoxic T cell proliferation upon localized implantation. When administered intravenously, DOX@SAL specifically targets and delivers drugs to activated neutrophils in vivo, mitigating neutrophil infiltration and suppressing postoperative inflammatory responses. In vivo and vitro experiments have demonstrated that S-CV plus DOX@SAL, a combined chemo-immunotherapeutic strategy, has a remarkable potential to inhibit postoperative local tumor recurrence and distant tumor progression, with minimal systemic toxicity, providing a new concept for postoperative treatment of tumors.展开更多

The majority ...Crohn's disease (CD) is a chronic inflammatory disease of the digestive tract with systemic manifestations. Etiology is unknown, even if immunological, genetic and environmental factors are involved. The majority of CD patients require surgery during their lifetime due to progressive bowel damage, but, even when all macroscopic lesions have been removed by surgery, the disease recurs in most cases. Postoperative management represents therefore a crucial mean for preventing recurrence. Several drugs and approaches have been proposed to achieve this aim. Endoscopic inspection of the ileocolic anastomosis within 1 year from surgery is widely encouraged, given that endoscopic recurrence is one of the greatest predictors for clinical recurrence. A strategy should be planned only after stratifying patients according to their individual risk of recurrence, avoiding unnecessary therapies when possible benefits are reduced, and selecting high-risk patients for more aggressive intervention.展开更多

Approximately 40% of patients with GIBD and 23.6% of patients withCD developed postoperative complications, 50% of patients with GIBD and 38.7%of patients with CD had recurrence postoperatively, and 40% (4/10) of patientswith GIBD and 26.4% (28/106) of patients with CD underwent reoperations. Theaverage period of postoperative recurrence was 7.87 mo in patients with Behçet'sdisease (BD) and 10.43 mo in patients with CD, whereas the mean duration fromfirst surgery to reoperation was 5.75 mo in BD patients and 18.04 mo in CDpatients. Surgical patients with GIBD more often used corticosteroids (6/10 vs7/106, P < 0.001) and thalidomide (7/10 vs 9/106, P < 0.001) postoperatively,whereas surgical patients with CD often used infliximab (27/106), azathioprine,or 6-mercaptopurine (74/106) for maintenance therapy.CONCLUSIONPatients suffering GIBD require surgery mostly under emergency situations,which may be more susceptible to recurrence and reoperation and need moreaggressive postoperative treatment than patients with CD.展开更多

Smokers, those with perforating disease, and those with myenteric plexitis are all at higher risk of recurrence. A number of medical therapies have been shown to reduce this risk in clinical trials. Metronidazole, thiopurines and anti-tumour necrosis factors (TNFs) are all effective in reducing the risk of endoscopic or clinical recurrence of CD. Since these are preventative agents, the benefits of prophylaxis need to be weighed-against the risk of adverse events from, and costs of, therapy. Patients who are high risk for post-operative recurrence should be considered for early medical prophylaxis with an anti-TNF. Patients who have few to no risk factors are likely best served by a three-month course of antibiotics followed by tailored therapy based on endoscopy at one year. Clinical recurrence rates are variable, and methods to stratify patients into high and low risk populations combined with prophylaxis tailored to endoscopic recurrence would be an effective strategy in treating these patients.展开更多

However, chemotherapy intervention after surgery is often unsatisfactory, because residual microtumors are difficult to target and require frequent administration. Here, an all-in-one and oncefor-all drug depot based on in situ-formed hydrogel was applied to fit the irregular surgical trauma, and enable direct contact with residual tumors and sustained drug release. Our immunological analysis after resection of orthotopic breast tumor revealed that postsurgical activation of CXCR4-CXCL12 signal exacerbated the immunosuppression and correlated with adaptive upregulation of PD-L1 in recurrent tumors. Thus, a multifunctional hydrogel toolkit was developed integrating strategies of CXCR4 inhibition,immunogenicity activation and PD-L1 blockade. Our results showed that the hydrogel toolkit not only exerted local effect on inhibiting residual tumor cell “seeds” but also resulted in abscopal effect on disturbing pre-metastatic “soil”. Furthermore, vaccine-like effect and durable antitumor memory were generated, which resisted a secondary tumor rechallenge in 100% cured mice. Strikingly, one single dose of such modality was able to eradicate recurrent tumors, completely prevent pulmonary metastasis and minimize off-target toxicity, thus providing an effective option for postoperative intervention.展开更多
