RESUMO
BACKGROUND: The enhanced recovery after surgery (ERAS) is nowadays a widely accepted multimodal programme of care in colorectal surgery, but still there is some reluctance in its application to very elderly patients. AIM: The aim of this study is to investigate short-term outcomes of laparoscopic resection for colorectal cancer in octogenarian patients within the ERAS programme. METHODS: Data on 162 consecutive patients aged ≥ 80 years receiving elective minimally invasive colorectal resections within ERAS programme were collected in a multicentre, retrospective database in the period 2008-2017 in Italy. Univariate and multivariate analyses were performed to assess possible risk factors for poor clinical outcomes. RESULTS: The postoperative minor morbidity rate (Clavien-Dindo 1 and 2) was 25.9%. The incidence of postoperative major morbidity rate (severe medical and surgical complications defined as Clavien-Dindo 3 and 4) accounted 6.1% and only 1.8% had an anastomotic leakage. Reoperation rate was 5.5%, perioperative 30-day mortality was 1.8%, and 30-day readmission rate was 6.8%. On average, patients were released after 6 days. A univariate analysis showed that possible risk factors for severe medical complications were: low preoperative albumin level, high Charlson Age Comorbidity Index Score and number of days in the intensive care unit (ICU); risk factors for severe surgical complications were: low preoperative albumin level; risk factors for late hospital discharge were: multivisceral resections, number of days in ICU and body mass index (BMI) > 25 kg/m2. The multivariate analysis confirmed a low level of preoperative albumin and a longer ICU stay as independent risk factors for both postoperative severe surgical complications and late hospital discharge. DISCUSSION: The minimal invasive nature of the laparoscopic approach together with a multimodal analgesia therapy, the early resumption to oral diet and mobilisation could minimize the surgical stress and play an essential role in order to reduce medical morbidity in high-risk patients. CONCLUSION: Colorectal surgery within ERAS programme in octogenarians is a safe and flexible treatment in high-volume centres.

OBJECTIVE: True superficial femoral artery aneurysms (SFAAs) are rare and traditionally treated by open repair. However, the endovascular approach excluding the aneurysm sac with a covered stent may be an alternative. This study aimed to compare the outcomes of the open and endovascular repair of SFAAs. METHODS: This is a retrospective, observational, monocentric study. The main endpoints were: technical success, limb salvage and primary patency rate, and hospitalisation time. RESULTS: We identified 49 SFAAs in 40 patients; the mean age was 73.3±10.1 years, the mean diameter of SFAAs was 5.41±3.64cm, and 61.2% were symptomatic for ischaemic or compression-related signs. The indication for open repair was given mainly for complex SFAAs involving the distal third of the superficial femoral artery and with an ipsilateral popliteal aneurysm. Among the 36 open-repair patients, 33 underwent ligation and revascularisation via bypass or graft interposition, and 3 patients underwent simple ligation without revascularisation. The endovascular approach was adopted mainly for aneurysms located in the medial third of the SFAA, which underwent covered stenting in 12 patients and coil embolisation in 1 patient. The technical success was 100% in all cases. There were no statistical differences in terms of primary patency and limb salvage rate between groups at two and four years. The mean hospitalisation time was 10±4 and 3±1 days after open and endovascular treatment, respectively. CONCLUSIONS: The endovascular approach may be a valid alternative for isolating SFAAs offering good results and shorter hospitalisation. Open repair remains a valid approach, particularly in complex aneurysms.
RESUMO
After surgical treatment of Charcot neuro-osteoarthropathy (CNO) complicated by plantar ulcer and midtarsal osteomyelitis, offloading is mandatory to protect the surgical site. Total contact casting is, to date, the standard-of-care to offload the foot during the postoperative period. We have compared the application of external circular fixator, to the standard of care, with regard to surgical wound healing and time to healing. During the time period from January 2020 to December 2021, 71 consecutive patients admitted to our unit with diabetes and CNO complicated by plantar ulceration and midtarsal osteomyelitis were enrolled in our study. All patients were classified as stage 2, according to the Frykberg & Sanders classification. Wifi wound stage was W2 I0 FI2 in 43 of 71 patients (60.6%) and W2 I2 FI2 in 28 of 71 patients (39.4%). In cases where critical limb ischemia occurred, we performed an endovascular procedure to obtain patency in at least one of the tibial arteries. Localization of osteomyelitis was carried out with magnetic resonance imaging studies, and the degree of deformity was assessed using plain X-ray or computed tomography. A localized ostectomy through the ulceration was carried out with a fasciocutaneous flap to cover the surgical site. In 36 patients, an external circular fixator was applied intraoperatively (exfix+ group); the remaining 35 patients received fiberglass cast in the postoperative period (exfix- group). Complete healing of the surgical site was achieved in 36 of 36 patients in the exfix+ arm and in 22 of 35 in the exfix- arm (P < .02). Time to healing was 68 ± 28 days in exfix+ and 102 ± 88 days in exfix- (P = .05). Circular external frames should be considered as an effective offloading device that enhances the healing rate and reduces time to healing after surgical treatment of midfoot osteomyelitis in subjects affected by CNO.
RESUMO
BACKGROUND: Deep infiltrating endometriosis (DIE) is a complex disease that impairs the quality of life and the fertility of women. Since a medical approach is often insufficient, a minimally invasive approach is considered the gold standard for complete disease excision. Robotic-assisted surgery is a revolutionary approach, with several advantages compared with traditional laparoscopic surgery. METHODS: From March 2010 to May 2011, we performed 22 consecutive robotic-assisted complete laparoscopic excisions of DIE endometriosis with colorectal involvement. All clinical data were collected by our team and all patients were interviewed preoperatively and 3 and 6 months post-operatively and yearly thereafter regarding endometriosis-related symptoms. Dysmenorrhoea, dyschezia, dyspareunia and dysuria were evaluated with a 10-point analog rating scale. RESULTS: There were 12 patients, with a median larger endometriotic nodule of 35 mm, who underwent segmental resection, and 10 patients, with a median larger endometriotic nodule of 30 mm, who underwent complete nodule debulking by colorectal wall-shaving technique. No laparotomic conversions were performed, nor was any blood transfusion necessary. No intra-operative complications were observed and, in particular, there were no inadvertent rectal perforations in any of the cases treated by the shaving technique. None of the patients had ileostomy or colostomy. No major post-operative complications were observed, except one small bowel occlusion 14 days post-surgery that was resolved in 3 days with medical treatment. Post-operatively, a statistically significant improvement of patient symptoms was shown for all the investigated parameters. CONCLUSIONS: To our knowledge, this is the first study reporting the feasibility and short-term results and complications of laparoscopic robotic-assisted treatment of DIE with colorectal involvement. We demonstrate that this approach is feasible and safe, without conversion to laparotomy.

After a cerebral stroke, survivors need to follow a neurorehabilitation program including exercises to be executed under a therapist's supervision or autonomously. Technological solutions are needed to support the early discharge of the patients just after the primary hospital treatments, by still providing an adequate level of rehabilitation. The DoMoMEA Project proposes a fully-wearable m-health solution able to administer a neurorehabilitation therapy in the patient's home or every other place established by the patient for a rehabilitation session. The exploitation of magneto-inertial measurement units only, wirelessly connected to an Android-operated device, provides robustness to different operating conditions and immunity to optical occlusion problems, compared to RGB-D cameras. Patients' engagement is fostered by the exploitation of the exergame version of the ten rehabilitation exercises, implemented in Unity 3D. Store-and-forward telemonitoring features, supported by cloud-based storage and by a web application accessible from anywhere by medical personnel and patients, enable constant transparent monitoring of the rehabilitation progresses. The clinical trial of the DoMoMEA telerehabilitation system will involve 40 post-stroke patients with mild impairment and will start as soon as the restrictions due to the COVID-19 pandemic will allow to enroll patients.

PURPOSE: The advantages of biological meshes for ventral hernia repair are still under debate. Given the high financial cost, the proper indications for biological meshes should be clarified to restrict their use to properly selected patients. METHODS: A retrospective database was instituted to register all cases of abdominal wall defect treated with biological meshes from 1/2010 to 3/2016. RESULTS: A total of 227 patients (mean age: 64 years) whose ventral abdominal defects were reconstructed with a biological mesh were included in the study. Patients were divided according to the 2010 four-level surgical-site complication risk grading system proposed by the Ventral Hernia Working Group (VHWG): Grade 1 (G1, 12 cases), Grade 2 (G2, 68 cases), Grade 3 (G3, 112 cases), and Grade 4 (G4, 35 cases). The surgical site complication rate was higher in patients with one or more risk factors (33.6% vs 19% in patients with no risk factors) (P = 0.68). Statistically significant risk factors associated with the onset of one or more postoperative surgical site complications included: diabetes, coronary artery disease, immunosuppression, and obesity. Recurrence was more common in patients with surgical site complications and mainly associated with infection (38.9%) and wound necrosis (44.4%), and in cases of inlay positioning of the mesh (36%). CONCLUSIONS: Due to their high costs, biological mesh should not be used in G1 patients. In infected fields (G4), they should only be used if no other surgical solution is feasible. There is a clear need to prospectively evaluate the performance of biological meshes.

Enhanced Recovery After Surgery (ERAS) pathway is a multi-disciplinary, patient-centered protocol relying on the implementation of the best evidence-based perioperative practice. In the field of colorectal surgery, the application of ERAS programs is associated with up to 50% reduction of morbidity rates and up to 2.5 days reduction of postoperative hospital stay. However, widespread adoption of ERAS pathways is still yet to come, mainly because of the lack of proper information and communication. Purpose of this paper is to support the diffusion of ERAS pathways through a critical review of the existing evidence by members of the two national societies dealing with ERAS pathways in Italy, the PeriOperative Italian Society (POIS) and the Associazione Italiana Chirurghi Ospedalieri (ACOI), showing the results of a consensus development conference held at Matera, Italy, during the national ACOI Congress on June 10, 2019.

Dynamic AngioThermography (DATG) is a contact-plate technique capable of producing a digital representation of breast vascularity. The inception and growth of a tumor are associated with neoangenesis, which may result in a demonstrable alteration in the regional blood flow, while in normal health conditions the vascularity remains unchanged throughout life. DATG, if included in the clinical evaluation for breast cancer, could potentially improve the accuracy of the diagnosis of this disease. Conventional DATG is limited, however, in that it is a projection (i.e. two-dimensional) imaging technique that does not provide any information on the depth and its effect on the pattern of the perfusion revealed by this technique. In fact, the blood pattern is detected by projecting temperature signals on the plate, thus acquiring a digital two-dimensional image. In this article we propose a new approach for extracting information on depth through the inversion of the Fourier heat equation. The idea is to extract the information along the third axis while acquiring and analyzing the temporal sequence during the process of image formation. The method implemented has been tested on a dedicated "electric phantom" and in one in vivo experiment. In spite of the limits of these preliminary tests, the experimental results have shown that this method makes it possible to obtain a 3D representation of the vascularity. Although it appears to be promising, further validation and characterization of our technique are required.

Dual-energy mammographic imaging experimental tests have been performed using a compact dichromatic imaging system based on a conventional x-ray tube, a mosaic crystal, and a 384-strip silicon detector equipped with full-custom electronics with single photon counting capability. For simulating mammal tissue, a three-component phantom, made of Plexiglass, polyethylene, and water, has been used. Images have been collected with three different pairs of x-ray energies: 16-32 keV, 18-36 keV, and 20-40 keV. A Monte Carlo simulation of the experiment has also been carried out using the MCNP-4C transport code. The Alvarez-Macovski algorithm has been applied both to experimental and simulated data to remove the contrast between two of the phantom materials so as to enhance the visibility of the third one.

Physical properties of a position-sensitive camera for the analysis of biodistributions of gamma- and beta-emitting radiopharmaceuticals in small animals have been studied, in order to achieve optimal operating conditions. The camera consisted of a highly segmented yttrium-aluminate perovskite (YAP) scintillator, coupled to a position-sensitive photomultiplier. The energy resolution, the detection efficiency, the spatial resolution, the spatial linearity and the count-rate linearity of the YAP camera have been determined. Images related to initial activity levels and successive biodistribution evolution in mice organs are presented as an illustration of the camera performance.

This work proposes a compact dichromatic imaging system for the application of the K-edge digital subtraction technique based on a conventional x-ray tube and a monochromator system. A quasi-monochromatic x-ray beam at the energy of iodine K-edge is produced by Bragg diffraction on a mosaic crystal. Two thin adjacent beams with energies that bracket the K-edge discontinuity are obtained from the diffracted beam by means of a proper collimation system. They are then detected using an array of Si detectors. A home-made phantom is used to study the image quality as a function of iodine concentration. Signal and signal-to-noise ratio analysis has also been performed. The results are compared with theoretical expectations.

Acute pancreatitis is one of the most serious complications in endoscopic cholangio-pancreatography (ERCP) and endoscopic sphincterotomy (EPT). Many attempts to avoid such complication have proved to be unsuccessful. The aim of this study was to evaluate the therapeutic effect of octreotide acetate in preventing acute pancreatitis following ERCP. The study was carried out over 100 patients, randomly allocated in two groups. The first group of patients (50 pt.) received 0.1 mg of octreotide acetate s.c. 45 minutes before the ERCP, followed by another dose given 6 hours later. The second group received placebo s.c.
