ABSTRACT

Introduction: Around 20% of population in western countries is under anticoagulant treatment. However, there is paucity of evidence about the treatment of HD in patients under anticoagulant/antiplatelet therapy, although both suspension and continuation in the perioperative period may increase the risk of severe complications. The aim of this pilot study was to confirm the feasibility and safety of sclerobanding (Combined Rubber Band Ligation with 3% Polidocanol Foam Sclerotherapy), an office-based procedure, for the treatment of second-and third-degree HD in patients under anticoagulant/antiplatelet therapy without suspension. Materials and methods: Patients affected by second-third-degree haemorrhoids unresponsive to conservative treatment and under anticoagulant/antiplatelet were enrolled between November 2019 and October 2021. Postoperative complications, readmission, mortality and reintervention during the follow-up were evaluated. Results: Fifty-one patients were recruited, 23 female (45.1%) and 28 male (54.9%), with an average age of 65 years ± 11.4 SD (range 42-90). Twenty-seven patients (52.9%) had II-degree haemorrhoidal disease, and 24 (47.1%) had grade III-degree. The most frequently taken medications were dual antiplatelet therapy (51%) and new oral anticoagulants (NOACs) (21.6%). The mean follow-up was 23 months. No intraoperative complications were recorded. The rate of complications in the first postoperative month was 13.7%, represented by mild complications: 6 cases of moderate to severe pain and 1 case (2%) of thrombosis of a residual haemorrhoidal nodule, all regressing after conservative therapy. No severe complications were reported. Postoperative complications were not statistically significantly associated with the number of nodules treated (1, 2, or 3), the disease grade (2nd vs. 3rd) or the specific anticoagulant/antiplatelet regimen. During follow-up, 2 patients (4%) required a new procedure for recurrent bleeding: one an infrared photocoagulation as outpatient, and another a haemorrhoidectomy after 3 months. No cases of intraoperative or postoperative mortality occurred. Conclusions: Sclerobanding is a safe and effective technique in treating intermediate-grade haemorrhoidal disease in patients at high risk on anticoagulant/antiplatelet therapy. Sclerobanding is repeatable, usually does not require anaesthesia, and is cost-effective. Observational multicentre studies with a larger number of patients and controlled clinical trials will be needed to confirm these results.

ABSTRACT

Oligometastatic disease has been described as an intermediate clinical state between localized cancer and systemically metastasized disease. Recent clinical studies have shown prolonged survival when aggressive locoregional approaches are added to systemic therapies in patients with oligometastases. The aim of this review is to outline the newest options to treat oligometastatic colorectal cancer (CRC), also considering its molecular patterns. We present an overview of the available local treatment strategies, including surgical procedures, stereotactic body radiation therapy (SBRT), thermal ablation, as well as trans-arterial chemoembolization (TACE) and selective internal radiotherapy (SIRT). Moreover, since imaging methods provide crucial information for the early diagnosis and management of oligometastatic CRC, we discuss the role of modern radiologic techniques in selecting patients that are amenable to potentially curative locoregional treatments.

ABSTRACT

BACKGROUND: The identification of metastatic lymph nodes is one of the most important prognostic factors in gastrointestinal (GI) cancers. Near-infrared fluorescence (NIRF) imaging has been successfully used in GI tumors to detect the lymphatic pathway and the sentinel lymph node (SLN), facilitating fluorescence image-guided surgery (FIGS) with the purpose to achieve a correct nodal staging. The aim of this study was to analyze the current results of NIRF SLN navigation and lymphography through data collected in the EURO-FIGS registry. METHODS: Prospectively collected data regarding patients and ICG-guided lymphadenectomies were analyzed. Additional analyses were performed to identify predictors of metastatic SLN and determinants of fluorescence positivity and nodal metastases outside the boundaries of standard lymphadenectomies. RESULTS: Overall, 188 patients were included by 18 surgeons from 10 different centers. Colorectal cancer was the most reported pathology (77.7%), followed by gastric (19.1%) and esophageal tumors (3.2%). ICG was injected with higher doses (p < 0.001) via extraparietal side (63.3%), and with higher volumes (p < 0.001) via endoluminal side (36.7%). Overall, NIRF SLN navigation was positive in 75.5% of all cases and 95.5% of positive SLNs were retrieved, with a metastatic rate of 14.7%. NIRF identification of lymph nodes outside standard lymphatic stations occurred in 52.1% of all cases, 43.8% of which were positive for metastatic involvement. Positive NIRF SLN identification was an independent predictor of metastasis outside standard lymphatic stations (OR = 4.392, p = 0.029), while BMI independently predicted metastasis in retrieved SLNs (OR = 1.187, p = 0.013). Lower doses of ICG were protective against NIRF identification outside standard of care lymphadenectomy (OR = 0.596, p = 0.006), while higher volumes of ICG were predictive of metastatic involvement outside standard of care lymphadenectomy (OR = 1.597, p = 0.001). CONCLUSIONS: SLN mapping helps identifying potentially metastatic lymph nodes outside the boundaries of standard lymphadenectomies. The EURO-FIGS registry is a valuable tool to share and analyze European surgeons' practices.

ABSTRACT

Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. On the other hand, useful complementary information is provided by hyperon decay measurements. We summarize the relevant phenomenological models and the status of the searches in a comprehensive list of kaon and hyperon decay channels. We identify new search strategies for under-explored signatures, and demonstrate that the improved sensitivities from current and next-generation experiments could lead to a qualitative leap in the exploration of light dark sectors.

ABSTRACT

OBJECTIVE: To investigate the predictive role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the assessment of response to total neoadjuvant therapy (TNT) in patients with locally advanced rectal cancer (LARC). METHODS: In this single-center retrospective study, patients with LARC who underwent staging MRI and TNT were enrolled. MRI-based staging, tumor volume, and DWI-ADC values were analyzed. Patients were classified as complete responders (pCR) and non-complete responders (non-pCR), according to post-surgical outcome. Pre-treatment ADC values were compared to pathological outcome, post-treatment downstaging, and reduction of tumor volume. The diagnostic accuracy of DWI-ADC in differentiating between pCR and non-pCR groups was calculated with receiver operating characteristic (ROC) analysis. RESULTS: A total of 36 patients were evaluated (pCR, n = 20; non-pCR, n = 16). Pre-treatment ADC values were significantly different between the two groups (p = 0.034), while no association was found between pre-TNT tumor volume and pathological response. ADC values showed significant correlations with loco-regional downstaging after therapy (r = -0.537, p = 0.022), and with the reduction of tumor volume (r = -0.480, p = 0.044). ADC values were able to differentiate pCR from non-pCR patients with a sensitivity of 75% and specificity of 70%. CONCLUSIONS: ADC values on pre-treatment MRI were strongly associated with the outcome in patients with LARC, both in terms of pathological response and in loco-regional downstaging after TNT, suggesting the use of DW-MRI as a potential predictive tool of response to therapy. KEY POINTS: • ADC values of pre-TNT MRI examinations of patients with LARC were significantly associated with a pathological complete response (pCR) and with post-treatment regression of TNM staging. • An ADC value of 1.042 ×10-3 mm2/s was found to be the optimal cutoff value for discriminating between pCR and non-pCR patients, with a sensitivity of 75% and specificity of 70%. • DW-MRI proved to have a potential predictive role in the assessment of response to therapy in patients with LARC, throughout the analysis of ADC map values.

ABSTRACT

(1) Background: Fluorescence cholangiography has been proposed as a method for improving the visualization and identification of extrahepatic biliary anatomy in order to possibly reduce injuries and related complications. The most common method of indocyanine green (ICG) administration is the intravenous route, whereas evidence on direct ICG injection into the gallbladder is still quite limited. We aimed to compare the two different methods of ICG administration in terms of the visualization of extrahepatic biliary anatomy during laparoscopic cholecystectomy (LC), analyzing differences in the time of visualization, as well as the efficacy, advantages, and disadvantages of both modalities. (2) Methods: A total of 35 consecutive adult patients affected by acute or chronic gallbladder disease were enrolled in this prospective case−control study. Seventeen patients underwent LC with direct gallbladder ICG injection (IC-ICG) and eighteen subjects received intravenous ICG administration (IV-ICG). (3) Results: The groups were comparable with regard to their demographic and perioperative characteristics. The IV-ICG group had a significantly shorter overall operative time compared to the IC-ICG group (p = 0.017). IV-ICG was better at delineating the duodenum and the common hepatic duct compared to the IC-ICG method (p = 0.009 and p = 0.041, respectively). The cystic duct could be delineated pre-dissection in 76.5% and 66.7% of cases in the IC-ICG and IV-ICG group, respectively, and this increased to 88.2% and 83.3% after dissection. The common bile duct could be highlighted in 76.5% and 77.8% of cases in the IC-ICG and IV-ICG group, respectively. Liver fluorescence was present in one case in the IC-ICG group and in all cases after IV-ICG administration (5.8% versus 100%; p < 0.0001). (4) Conclusions: The present study demonstrates how ICG-fluorescence cholangiography can be helpful in identifying the extrahepatic biliary anatomy during dissection of Calot's triangle in both administration methods. In comparison with intravenous ICG injection, the intracholecystic ICG route could provide a better signal-to-background ratio by avoiding hepatic fluorescence, thus increasing the bile duct-to-liver contrast.

ABSTRACT

BACKGROUND/AIM: To compare clinical outcomes following intensified total neoadjuvant therapy (TNT) and intensified neoadjuvant chemoradiotherapy (CRT) in patients with locally advanced rectal cancer (LARC). PATIENTS AND METHODS: Of the 79 patients with LARC admitted to our department, 51 received intensified neoadjuvant CRT (CRT group) and 28 received intensified TNT (TNT group). Intensified TNT was defined as multi-agent chemotherapy, including FOLFOXIRI regimen plus bevacizumab (mutated Ras-BRAF) or panitumumab/cetuximab (wild-type Ras-BRAF) followed by oxaliplatin-5-fluorouracil-based CRT and surgery. Kaplan-Meier and Log rank test were used for survival analysis. Survival rates of the two groups were compared using propensity score matching. RESULTS: Data from 28 TNT patients and 28 CRT patients were analyzed after a 1:1 propensity matching with replacement. Kaplan-Meier curve showed that overall survival (OS), disease-free survival (DFS) and distant metastasis-free survival (DMFS) rates with TNT were comparable to those with CRT. The 5-year DMFS rates for TNT and CRT were 61.5% versus 63.0% (p=0.82), respectively. In the TNT group, 32.1% patients (n=9) achieved pathological complete response (pCR), whereas 21.4% patients (n=6) achieved pCR with CRT (p=0.37). CONCLUSION: Intensified TNT and CRT resulted in similar survival outcomes, while intensified TNT led to higher pCR, albeit not statistically significant.

ABSTRACT

BACKGROUND: Sentinel lymph node (SLN) mapping using near-infrared fluorescence (NIRF) imaging is a recent technique to improve nodal staging in several tumors. The presence of colorectal cancer (CRC) micro-metastases has recently been defined as N1 disease and no longer as N1mi, determining the need for adjuvant chemotherapy. In CRC, the reported rate of SLN micro-metastases detected by ultrastaging techniques is as high as 30%. The aim of this prospective study is to report the preliminary results of the sensitivity analysis of NIRF imaging for ex vivo SLN mapping and the research of micro-metastases in CRC, in patients with node-negative disease (NND). MATERIAL AND METHODS: On the specimen of 22 CRC patients, 1 mL of ICG (5 mg/mL) was injected submucosally around the tumor to identify SLNs. NND SLNs were further investigated with ultrastaging techniques. RESULTS: Three-hundred and sixty-three lymph nodes were retrieved (59 SLNs; mean per case: 2.7). The detection, sensitivity and false-negative rate were 100%, 100% and 0% respectively. Ultrastaging investigations showed no micro-metastases in the NND SLNs. CONCLUSIONS: The ex vivo SLN fluorescence-based detection in CRC was confirmed to be easy to perform and reliable. In this preliminary results report of an ongoing study, the SLN assay was congruent with the nodal status, as confirmed by histological investigations.

ABSTRACT

Bruno da Longobucco (1200-1286) was born at the turn of the 13th Century in Longobucco (Calabria, Italy), at that time named Longoburgo. He was the first academic surgeon of the Middle Ages, a period when surgery was disregarded by mainstream physicians and was the practice of barbers, charlatans and phlebotomists. After training at the medical school of Salerno and the University of Boulogne, he was one of the founders of the University of Padua and became the first Professor of Surgery. His books Chirurgia Magna and Chirurgia Parva, were ones of the most disseminated surgical texts of the Middle Ages and it is argued helped surgery regain its reputation. Despite his importance to late medieval period, he has been essentially overlooked in the records of the history of surgery. Currently, there are no articles in English about his life indexed on PubMed, Scopus or Embase. One solitary article on Bruno's life and influence was published in 1960s in a small journal in Italian, but this is no longer active and there is no electronic means to access the original article. The aim of this article is to provide education and rediscovery of the impact of this critical figure, his works and his historic role to the development and renaissance of surgery for contemporary surgeons.

ABSTRACT

Hemorrhoidal disease (HD) is the symptomatic enlargement and/or distal displacement of the normal hemorrhoidal cushions and is one of the most frequent diseases in colorectal surgery. Several surgical or office-based therapies are currently available, with the aim of being a more tailored approach. This article aimed to elucidate the historical evolution of surgical therapy for HD from ancient times, highlighting the crucial steps, controversies, and pioneers in the field. In contrast with the previous literature on the topic that is often updated to the 1990s, with the introduction of stapled hemorrhoidopexy and transanal hemorrhoidal dearterialization, this article describes all new surgical and office-based treatments introduced in the first 20 years of the 2000s.

ABSTRACT

BACKGROUND: Anastomotic leakage (AL) is one of the dreaded complications following surgery in the digestive tract. Near-infrared fluorescence (NIRF) imaging is a means to intraoperatively visualize anastomotic perfusion, facilitating fluorescence image-guided surgery (FIGS) with the purpose to reduce the incidence of AL. The aim of this study was to analyze the current practices and results of NIRF imaging of the anastomosis in digestive tract surgery through the EURO-FIGS registry. METHODS: Analysis of data prospectively collected by the registry members provided patient and procedural data along with the ICG dose, timing, and consequences of NIRF imaging. Among the included upper-GI, colorectal, and bariatric surgeries, subgroup analysis was performed to identify risk factors associated with complications. RESULTS: A total of 1240 patients were included in the study. The included patients, 74.8% of whom were operated on for cancer, originated from 8 European countries and 30 hospitals. A total of 54 surgeons performed the procedures. In 83.8% of cases, a pre-anastomotic ICG dose was administered, and in 60.1% of cases, a post-anastomotic ICG dose was administered. A significant difference (p < 0.001) was found in the ICG dose given in the four pathology groups registered (range: 0.013-0.89 mg/kg) and a significant (p < 0.001) negative correlation was found between the ICG dose and BMI. In 27.3% of the procedures, the choice of the anastomotic level was guided by means of NIRF imaging which means that in these cases NIRF imaging changed the level of anastomosis which was first decided based on visual findings in conventional white light imaging. In 98.7% of the procedures, the use of ICG partly or strongly provided a sense of confidence about the anastomosis. A total of 133 complications occurred, without any statistical significance in the incidence of complications in the anastomoses, whether they were ICG-guided or not. CONCLUSION: The EURO-FIGS registry provides an insight into the current clinical practice across Europe with respect to NIRF imaging of anastomotic perfusion during digestive tract surgery.

ABSTRACT

BACKGROUND: Sclerobanding is a novel technique combining rubber band ligation with 3% polidocanol foam sclerotherapy for the treatment of hemorrhoidal disease (HD). The aim of this study is to evaluate the feasibility, safety and short-term outcomes of sclerobanding in the treatment of second- and third-degree HD. METHODS: A retrospective analysis of second- and third-degree HD cases from November 2017 to August 2021 was performed. Patients on anticoagulants or with other HD degrees were excluded. Follow-up was conducted at 1 month, 3 months, 6 months, 1 year and then every 12 months. RESULTS: 97 patients with second- (20 pts; 20.6%) and third-degree (77 pts; 79.4%) HD with a mean age of 52 years (20-84; SD ± 15.5) were included. Fifty-six patients were men (57.7%) and forty-one women (42.3%). Median follow-up was 13 months (1-26 months). No intraoperative adverse events or drug-related side effects occurred. Minor complications occurred in four patients (4.1%) in the first 30 postoperative days and all resolved after conservative treatment at the 3-month follow-up visit. No mortality or readmissions were observed. CONCLUSIONS: Sclerobanding is a safe technique with a low rate of minor postoperative complications. Further studies on larger samples are necessary to establish the effectiveness and long-term outcomes of the technique.

ABSTRACT

BACKGROUND: In the past three decades, different High Energy Devices (HED) have been introduced in surgical practice to improve the efficiency of surgical procedures. HED allow vessel sealing, coagulation and transection as well as an efficient tissue dissection. This survey was designed to verify the current status on the adoption of HED in Italy. METHODS: A survey was conducted across Italian general surgery units. The questionnaire was composed of three sections (general information, elective surgery, emergency surgery) including 44 questions. Only one member per each surgery unit was allowed to complete the questionnaire. For elective procedures, the survey included questions on thyroid surgery, lower and upper GI surgery, proctologic surgery, adrenal gland surgery, pancreatic and hepatobiliary surgery, cholecystectomy, abdominal wall surgery and breast surgery. Appendectomy, cholecystectomy for acute cholecystitis and bowel obstruction due to adhesions were considered for emergency surgery. The list of alternatives for every single question included a percentage category as follows: " < 25%, 25-50%, 51-75% or > 75%", both for open and minimally-invasive surgery. RESULTS: A total of 113 surgical units completed the questionnaire. The reported use of HED was high both in open and minimally-invasive upper and lower GI surgery. Similarly, HED were widely used in minimally-invasive pancreatic and adrenal surgery. The use of HED was wider in minimally-invasive hepatic and biliary tree surgery compared to open surgery, whereas the majority of the respondents reported the use of any type of HED in less than 25% of elective cholecystectomies. HED were only rarely employed also in the majority of emergency open and laparoscopic procedures, including cholecystectomy, appendectomy, and adhesiolysis. Similarly, very few respondents declared to use HED in abdominal wall surgery and proctology. The distribution of the most used type of HED varied among the different surgical interventions. US HED were mostly used in thyroid, upper GI, and adrenal surgery. A relevant use of H-US/RF devices was reported in lower GI, pancreatic, hepatobiliary and breast surgery. RF HED were the preferred choice in proctology. CONCLUSION: HED are extensively used in minimally-invasive elective surgery involving the upper and lower GI tract, liver, pancreas and adrenal gland. Nowadays, reasons for choosing a specific HED in clinical practice rely on several aspects, including surgeon's preference, economic features, and specific drawbacks of the energy employed.

ABSTRACT

Following the spread of the infection from the new SARS-CoV2 coronavirus in March 2020, several surgical societies have released their recommendations to manage the implications of the COVID-19 pandemic for the daily clinical practice. The recommendations on emergency surgery have fueled a debate among surgeons on an international level.We maintain that laparoscopic cholecystectomy remains the treatment of choice for acute cholecystitis, even in the COVID-19 era. Moreover, since laparoscopic cholecystectomy is not more likely to spread the COVID-19 infection than open cholecystectomy, it must be organized in such a way as to be carried out safely even in the present situation, to guarantee the patient with the best outcomes that minimally invasive surgery has shown to have.

ABSTRACT

Transanal endoscopic microsurgery (TEM) is a type of natural orifice transluminal endoscopic surgery, developed for rectal tumors and used also to treat other rectal diseases. Anastomotic complications after colorectal surgery, including stenosis, represent a challenging problem. We present the case of a 36-year-old woman with a diagnosis of Hirschsprung disease that was submitted to a modified Duhamel operation. A postoperative barium enema showed a complete stricture of the anastomosis that was impossible to resolve by flexible endoscopic approach. Then an intraoperative endoscopic approach to facilitate the localization of preanastomotic colon (proximal colon from the anastomosis) was performed by a small colotomy and the colonic recanalization was obtained by the creation of a neo-anastomosis by TEM, under fluoroscopic-endoscopic control. The patient underwent a control barium enema showing regular retrograde transit of contrast medium without evidence of stenosis. In our experience, transanal approach by TEM-colonoscopy assisted is safe and feasible and represents a model of combined minimally invasive technique.

ABSTRACT

A correct lymph node (LN) staging is essential in oncological surgery. Indocyanine green (ICG) near-infrared fluorescence (NIRF) guided sentinel lymph node (SLN) navigation is a relatively novel technique. The aim of this review is to analyze the impact of ICG-NIRF on identification of LN metastases of gastrointestinal tumors. The Scopus and PubMed/MEDLINE literature databases were searched and 20 studies were included. The ICG-NIRF navigation of LN has been shown to enable and improve LN detection in gastrointestinal tumors; however, the mean detection, sensitivity, accuracy and false negative rates show substantial variation. This could be due to both the heterogeneous techniques applied and to the low retention of ICG by lymph nodes. Fluorescence imaging to identify LN drainage is a promising tool to improve oncological outcomes. Nonetheless, the technique requires further development in terms of hardware, software and fluorophores, which are currently being investigated.

ABSTRACT

BACKGROUND: Endoluminal loco-regional resection (ELRR) by transanal endoscopic microsurgery (TEM) may be an alternative treatment option to Laparoscopic total mesorectal excision (LTME), in selected patients with N0 rectal cancer. Post-operative quality of life (QoL) evaluation is an important parameter of outcomes related to high percentage of functional sequelae. We reported, in a previous paper, the short and medium term results of QoL in patients who underwent ELRR or LTME. The aim is to evaluate the 3 year QoL in patients with iT2-T3 N0/+ rectal cancer who underwent ELRR by TEM or LTME after neoadjuvant radio-chemotherapy (nChRT) in a retrospective analysis of prospectively collected data. METHODS: We enrolled in this study, 39 patients with iT2-T3 rectal cancer who underwent ELRR (n = 19) or LTME (n = 20), according to predefined criteria. QoL was evaluated by EORTC QLQ-C30 and QLQ-CR38 questionnaires at admission, after n-RCT and 1, 6, 12, and 36 months after surgery. RESULTS: No statistically significant differences in QoL evaluation were observed between the two groups, both at admission and after n-RCT. In short term (1-6 months) period, significantly better results were observed in ELRR group by QLQ-C30 in global health status (p = 0.03), physical functioning (p = 0.026), role functioning (p = 0.04), emotional functioning (p = 0.04), cognitive functioning, fatigue (p < 0.05), dyspnoea (p < 0.001), insomnia (p < 0.05), appetite loss (p < 0.05), constipation (≤ 0.05), and by QLQ-CR38 in: body image (p = 0.03) and defecation (p = 0.025). At 1 year, the two groups were homogenous as assessed by QLQ-C30, whereas the QLQCR38 still showed better results of ELRR versus LTME in body image (p = 0.006), defecation problems (p = 0.01), and weight loss (p = 0.005). At 3 years, no statistically significant differences were observed between the two groups.
