Nowadays, surgical innovations incorporate new technological conquests and must be validated by evidence-based medicine. The use of augmented reality-assisted indocyanine green (ICG) fluorescence has generated a myriad of intraoperative applications such as demonstration of key anatomical landmarks, sentinel lymph nodes, and real-time assessment of local blood flow. This paper presents a systematic review of the clinical evidence regarding the applications of ICG near-infrared (NIR) fluorescence in colorectal surgery. After we removed duplicate publications and screened for eligibility, a total of 36 articles were evaluated: 23 on perfusion assessment, 10 on lymph node mapping, and 3 on intraoperative identification of ureters. Lack of homogenous studies, low statistical power, and confounding evidence were found to be common amongst publications supporting the use of ICG in colorectal surgery, raising concerns over this seductive technique′s cost efficiency and redundancy. The compiled data showed that ICG NIR fluorescence may be a game-changer in particular situations, as proven for low colorectal anastomosis or lateral pelvic lymph node dissection, but it remains controversial for routine use and sentinel lymph node assessment. Further randomized studies are needed to confirm these conclusions. Future research directions include tumor-targeted fluorescence imaging and digital software for quantitative evaluation of fluorescence.

Bariatric surgery is an emerging therapeutic approach for obese type 2 diabetes mellitus (T2DM) patients, with proven benefits for achieving target glucose control and even remission of diabetes. However, the effect of bariatric surgery upon diabetic retinopathy is still a subject of debate as some studies show a positive effect while others raise concerns about potential early worsening effects. We performed a systematic review, on PubMed, Science Direct, and Web of Science databases regarding the onset and progression of diabetic retinopathy in obese T2DM patients who underwent weight-loss surgical procedures. A total of 6375 T2DM patients were analyzed. Most cases remained stable after bariatric surgery (89.6%). New onset of diabetic retinopathy (DR) was documented in 290 out of 5972 patients (4.8%). In cases with DR at baseline, progression was documented in 50 out of 403 (12.4%) and regression in 90 (22.3%). Preoperative careful preparation of hemoglobin A1c (HbA1c), blood pressure, and lipidemia should be provided to minimize the expectation of DR worsening. Ophthalmologic follow-up should be continued regularly in the postoperative period even in the case of diabetic remission. Further randomized trials are needed to better understand the organ-specific risk factors for progression and provide personalized counseling for T2DM patients planned for bariatric surgery.

The prevalence of diabetic foot complications is continuously increasing as diabetes has become one of the most important “epidemics” of our time. The main objective of this study was to describe the appropriate surgical intervention for the complicated neuropathic diabetic foot; the secondary goal was to find the risk factors associated with minor/major amputation and good or adverse surgical outcomes. This is an observational, retrospective study conducted between 1 January 2018 and 31 December 2019, which included 251 patients from the General Surgery Department at the Dr I. Cantacuzino Clinical Hospital in Bucharest with type II diabetes mellitus and neuropathic diabetic foot complications. The surgical conditions identified at admission were the following: osteitis (38.6%), infected foot ulcer (27.5%), gangrene (20.7%), infected Charcot foot (3.6%), non-healing wound (3.6%), necrosis (3.2%), and granulated wound (2.8%). We found that a minor surgical procedure (transmetatarsal amputation of the toe and debridement) was performed in 85.8% of cases, and only 14.2% needed major amputations. Osteitis was mainly associated with minor surgery (p = 0.001), while the gangrene and the infected Charcot foot were predictable for major amputation, with OR = 2.230, 95% CI (1.024–4.857) and OR = 5.316, 95% CI (1.354–20.877), respectively. Admission anemia and diabetic nephropathy were predictive of a major therapeutical approach, with p = 0.011, OR = 2.975, 95% CI (1.244–8.116) and p = 0.001, OR = 3.565, 95% CI (1.623–7.832), respectively. All the major amputations had a good outcome, while only several minor surgeries were interpreted as the adverse outcome (n = 24). Osteitis (45.8%) and admission anemia (79.2%) were more frequently associated with adverse outcomes, with p = 0.447 and p = 0.054, respectively. The complicated neuropathic diabetic foot requires a surgical procedure mainly associated with a good outcome.

Radio-ulnar synostosis is a rare complication which develops following forearm trauma, the main manifestation being stiffness and leading to the loss of pronation and supination. For the patient, it is a very frustrating experience due to the impairment of the normal function of the forearm, whereas for the surgeon the treatment is difficult as, unfortunately, there is no consensus regarding the best way to approach it. Many surgical techniques and other kinds of adjuvant therapies have been developed in an effort to solve this disability. This paper presents an overview of the principal factors which contribute to the development of synostosis and the best therapeutic approach methods found in the literature.

(1) Background: The COVID-19 pandemic put a great burden on national healthcare systems, causing delays and disruptions in the medical care of non-COVID-19 patients. This paper aims to analyze the COVID-19 pandemic impact upon the quality of care in colorectal surgery. (2) Materials and Methods: We performed a retrospective study on the colorectal cancer cases operated in the Fourth Department of General Surgery, Emergency Hospital Bucharest Romania, over the period March 2020–February 2021 (pandemic group) vs. March 2019–February 2020 (non-pandemic group). (3) Results: The number of patients in the pandemic group decreased by 70% (36 vs. 118 patients), with lower accessibility from rural areas (11.1% vs. 37.2%, p = 0.035). Most cases in the pandemic group were emergencies (69% vs. 37.3%, p = 0.009), admitted for bowel obstruction (63.8% vs. 27.9%, p = 0.008). There was no in-hospital COVID-19 infection in patients operated for colorectal cancer. The 30-day mortality was significantly higher in the pandemic group (25% vs. 6.7%, p = 0.017), mostly due to septic shock (36.1% vs. 5%, p = 0.0001). (4) Conclusions: Colorectal cancer surgery may be performed safely during the COVID-19 pandemic, with strict adherence to the SARS-CoV-2 prevention protocols. However, the significant increase in colorectal cancers in the emergency was associated with worse outcomes and higher mortality during the COVID-19 pandemic.

In recent decades, antibiotic-resistant bacteria have become an increasingly urgent public health concern. The uncontrolled use of antibiotics, along with inadequate implementation of prevention and control measures, is the primary factor contributing to this issue. The hospital environment is a major source of multidrug-resistant bacteria, and in recent years, there has been growing concern about hospital wastewater, which acts as a significant reservoir for these bacteria and their resistance genes. This situation leads to the spread of multidrug-resistant bacteria in the environment. One particular concern is Acinetobacter, especially Acinetobacter baumannii, which has emerged as a pathogenic threat in healthcare-associated infections. This bacterium is found in high densities in hospital wastewater. Most strains of A. baumannii express resistance not only to carbapenems but also to several other classes of antibiotics, including tetracyclines, fluoroquinolones, and aminoglycosides. These strains must be combated through effective measures. Bacteriophages represent a potential mitigation strategy for antibiotic-resistant Acinetobacter spp. originating from hospital wastewater. This review summarizes studies from online databases regarding the identification and characterization of Acinetobacter strains in hospital wastewater worldwide, and presents progress in isolating and characterizing bacteriophages against A. baumannii found in hospital wastewater.
