Reconstruction of an emergency thoracotomy wound with free rectus abdominis flap: Anatomic and radiologic basis for the surgical technique

An alcoholic 50-year-old male patient with a history of schizophrenia sustained stab wounds into both ventricles and left lung, and survived following an emergency department thoracotomy. The EDT wound, however became infected requiring serial debridements of soft tissue, rib cartilage and sternum. Regional flap options such as pectoralis major and latissimus dorsi muscle flaps could not be employed due to inadequate reach of these flaps. Additionally, bilateral transection of the internal mammary arteries during emergency thoracotomy eliminated the use of rectus abdominis muscles as pedicled flaps based on the superior epigastric vasculature. Therefore, the EDT wound was reconstructed by using the right rectus abdominis muscle as a free flap. The deep inferior epigastric vessels of the flap were anastomosed to the right internal mammary vessels proximal to their transection level in the third-forth intercostal space. The flap healed with no further wound complications

Structural Properties, Cytotoxicity, and Anti-Inflammatory Activity of Silver(I) Complexes with tris(p-tolyl)Phosphine and 5-Chloro-2-Mercaptobenzothiazole

The synthesis and characterization of the silver(I) chloride complex of formula {[AgCI(CMBZT)(TPTP)2] · (MeOH)} (1) (CMBZT = 5-chloro-2-mercaptobenzothiazole, TPTP = tris(p-tolyl)phosphine) is described. Also the structure of the hydrate derivative {[AgCI(TPTP)3] · (0.5 · H2O)} (2) of the corresponding known anhydrous silver complex (Zartilas et al., 2009), and the polymorph 3 of the known [AgI(TPTP)3] complex (Zartilas et al., 2009) were determined and compared with the known ones. In addition, the structure of the known one silver(I) cluster {[AgI(TPTP)]4} (4) (Meijboom et al., 2009) was re-determined at 120(2) K and possible Ag-Ag interactions were analyzed. The compounds 1–4 were characterized by X-ray crystallography at r.t (1) and 120 K (2–4). All these complexes and {[(Et3NH)+]2 · [Ag6(μ3-Hmna)4(μ3-mna)2]2− · (DMSO)2 · (H2O)} (5) (Hmna = 2-mercaptonicotinic acid) were evaluated for cytotoxic and anti-inflammatory activity. The in vitro testing of cytotoxic activity of 1–5 against leiomyosarcoma cancer cells (LMS), were evaluated with Trypan Blue and Thiazolyl Blue Tetrazolium Bromide or 3-(4.5-dimethylthiazol-2-yl)-2.5-diphenyltetrazolium bromide (MTT) assays. The flow cytometry assay for complex 1 and showed that at 15 μM of 1, 62.38% of LMS cells undergo apoptosis, while 7% of LMS cells undergo cell necrosis. The antitumor activity of 3 is comparable with that of its reported polymorph (Zartilas et al., 2009). The anti-inflammatory, activity of complexes 1–3 and 5 was also studied. The activity towards cell viability was 2 > 3 > 5 > 1 > 4, while the order of the inhibitory activity in cell growth proliferation follows the order, 2 > 3 > 1 > 4 > 5. The anti-inflammatory activity on the other hand is 1 > 2 > 5 > ⋯ >3

Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

Minimally invasive oesophagectomy for cancer in patients with HIV/AIDS: Considerations and future directions

The impact of HIV/AIDS on the treatment of oesophageal neoplasms remains undefined due to a lack of adequate data. We present our experience in treating patients with HIV/AIDS who have oesophageal cancer using minimally invasive techniques and discuss important key factors during perioperative management. Two men with HIV/AIDS underwent minimally invasive oesophagectomies in our department, with adequate clinical and oncological outcomes. Minimally invasive oesophagectomy can be safe and has the well-established benefits of minimally invasive techniques, offering good perioperative results and oncological outcomes in patients with HIV/AIDS. Multimodality therapy is crucial. © 2020 Royal College of Surgeons of England. All rights reserved

Treatment of fournier's gangrene with vacuum-assisted closure therapy as enhanced recovery treatment modality

Background/Aim: Fournier's gangrene is an uncommon, but extremely serious condition of necrotizing, soft tissue infection. There is a great debate regarding the management of larger defects and wound closure, with various techniques being described in the current literature. We aimed to present the surgical management of extensive Fournier's gangrene treated successfully with Vacuumassisted closure (VAC) therapy, a novel approach to treatment algorithm that can lead to a paradigm shift. Case: A 66-year-old male patient with Fournier's gangrene was treated with extensive surgical debridement, protective colostomy and VAC therapy. Results: After initial extensive surgical debridement, VAC therapy significantly improved the clinical and aesthetic condition of the patient. Conclusion: VAC therapy in Fournier's gangrene patients may be a safe and effective technique with favorable clinical outcomes, by improving and enhancing wound healing and recovery. © 2020 International Institute of Anticancer Research.
