ABSTRACT
Leiomyosarcomas (LMSs) are rare tumors originating from the muscular layer. We performed a literature review of cases of confirmed rectal leiomyosarcomas (rLMSs) to clarify the history of such an infrequent tumor arising at such an uncommon location. In this research local recurrence was related to poorly differentiated rLMS and no other association between recurrence and any criteria was found. Concerning overall survival (OS), rLMS patients developing recurrence presented shorter longevity compared with the group without.

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.

Introduction: Intussusception represents a rare form of bowel obstruction in the adult, which is defined as the telescoping of a proximal segment of the gastrointestinal tract into the lumen of the adjacent distal segment of the GI tract Case Report: We report the case of a 50-year-old woman was admitted in our hospital with acute bowel obstruction. CT showed intestinal occlusion secondary to intussusception. the patient underwent emergency surgery. Surgery confirmed intussusception at the level of the distal ileum (about 30 cm from the ileocecal valve) due to a 3-4 oval mass of hard consistency that appeared to be suspicious for GIST. Was performed a resection of the ileal segment involved associated with oncologically radical lymphadenectomy. The histological examination reported benign ileal mesenchymal neoformation compatible with inflammatory fibroid polyp. Patient had a regular course Discussion: In adults, 90% of invaginations manifest as a result of an organic lesion caused by benign or malignant tumors. The clinical presentation in adults is generally chronic or nonspecific. The emergence of acute symptoms due to complete intestinal obstruction occours in fewer than 20% of patients. Abdominal computed tomography (CT) is the most sensitive radiologic method to confirm intussusception. As many cases are secondary to organic pathologies with malignant potential, surgical resection of the affected bowel segment with oncological procedures is the primary method of treatment Conclusion: Due to the fact that adult intussusception is often frequently associated with organic lesions, surgical intervention is necessary. Treatment usually requires formal resection of the involved bowel segment. (www.actabiomedica.it).

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.

INTRODUCTION: A pandemic outbreak of novel coronavirus, named SARS-CoV-2 and responsible of Coronavirus Disease 2019 (COVID-19), has rapidly spread from China to Europe, being Northern Italy the first focus outside Asia. Little is known about the evolution of SARS-CoV-2 infection in patients undergoing surgery. PRESENTATION OF CASE: Here we report the first confirmed case of early postoperative SARS-CoV-2 infection in a patient recovering after Hartmann's procedure for acute diverticulitis. After an otherwise unevenful postoperative course, on post-operative day 8, the patient suddenly presented hyperpyrexia and cough, rapidly evolving to respiratory failure and death 36 h after symptoms onset. CT-scan identified bilateral, diffuse, interstitial pneumonitis and oropharyngeal swab test confirmed the presence of SARS-CoV-2. A previous contact with the partner, developing the same symptoms, remained unrecognized until ICU admission. DISCUSSION: During a pandemic outbreak, the early identification of SARS-CoV-2 infection of an inside patient initially considered to be infection-free has a pivotal importance not only for the prompt patient's management, but also to avoid infection spreading to other patients and hospital personnel.In the reported case, a more precise information to the patient regarding the imperative necessity to inform the medical personnel of any person of his entourage presenting, at any time, any tell-tale sign, symptom or examination which may be attributed to COVID-19, may have had allowed to anticipate patient's isolation and examinations and procedures aimed at identifying such an infection. CONCLUSION: Persistent hyperleucocytosis and increased CRP serum level in spite of uneventful postoperative course were the only, aspecific markers of an ongoing SARS-CoV-2 infection before symptoms' onset, and should be considered in future clinical practice in order to adopt the prompt and appropriate patient management and limit COVID-19 contagion in surgical units.
ABSTRACT
INTRODUCTION: Near-infrared fluorescence cholangiography (NIRF-C) is a popular application of fluorescence image-guided surgery (FIGS). NIRF-C requires near-infrared optimized laparoscopes and the injection of a fluorophore, most frequently Indocyanine Green (ICG), to highlight the biliary anatomy. It is investigated as a tool to increase safety during cholecystectomy. The European registry on FIGS (EURO-FIGS: www.euro-figs.eu ) aims to obtain a snapshot of the current practices of FIGS across Europe. Data on NIRF-C are presented. METHODS: EURO-FIGS is a secured online database which collects anonymized data on surgical procedures performed using FIGS. Data collected for NIRF-C include gender, age, Body Mass Index (BMI), pathology, NIR device, ICG dose, ICG timing of administration before intraoperative visualization, visualization (Y/N) of biliary structures such as the cystic duct (CD), the common bile duct (CBD), the CD-CBD junction, the common hepatic duct (CHD), Visualization scores, adverse reactions to ICG, operative time, and surgical complications. RESULTS: Fifteen surgeons (12 European surgical centers) uploaded 314 cases of NIRF-C during cholecystectomy (cholelithiasis n = 249, cholecystitis n = 58, polyps n = 7), using 4 different NIR devices. ICG doses (mg/kg) varied largely (mean 0.28 ± 0.17, median 0.3, range: 0.02-0.62). Similarly, injection-to-visualization timing (minutes) varied largely (mean 217 ± 357; median 57), ranging from 1 min (direct intragallbladder injection in 2 cases) to 3120 min (n = 2 cases). Visualization scores before dissection were significantly correlated, at univariate analysis, with ICG timing (all structures), ICG dose (CD-CBD), device (CD and CD-CBD), surgeon (CD and CD-CBD), and pathology (CD and CD-CBD). BMI was not correlated. At multivariate analysis, pathology and timing remained significant factors affecting the visualization scores of all three structures, whereas ICG dose remained correlated with HD visualization only. CONCLUSIONS: The EURO-FIGS registry has confirmed a wide disparity in ICG dose and timing in NIRF-C. EURO-FIGS can represent a valuable tool to promote and monitor FIGS-related educational and consensus activities in Europe.

Recently, Indocyanine Green (ICG)-enhanced fluorescence has been introduced in laparoscopic colorectal surgery to provide detailed anatomical informations. The aim of our study is the application of ICG imaging during laparoscopic colorectal resections: to assess anastomotic perfusion to reduce the risk of anastomotic leak, to facilitate vascular dissection when vascular anatomy of tumor site is unclear, and to identify ureter to prevent iatrogenic injury. After the transection, 5 ml of ICG solution is intravenously injected. A Full HD IMAGE1S camera, switching to NIR mode, in few seconds provides a real-time angiography of colonic perfusion. After anastomosis, another bolus is injected to confirm the anastomotic perfusion. When the tumor is localized in difficult site, the fluorescence provides a real-time angiography of tumor area vascularization to perform the vascular dissection. When the tumor is tightly attached to the ureter, the ICG solution injection through the catheter allows ureter identification. From November 2016, 38 patients were enrolled: ten left colectomies, 22 right colectomies, three transverse resections, and three splenic flexure resections. In five cases, intraoperative angiography led to the identification of vascular anatomy. In one case the surgical strategy was changed. In one procedure, ureter identification allowed to prevent injury. Three postoperative complications that required surgical reoperation occured, of which one anastomotic leak, due to a mechanical problem. ICG-enhanced fluorescence imaging is a safe, cheap and effective tool to increase visualization during surgery. It can be employed also in small hospitals without learning curve. It is recommended to obtain additional information on anatomy and perfusion in colorectal surgery.

INTRODUCTION: De Garengeot Hernia is described as the presence of an appendix within a femoral hernia. CASE REPORT: We report the case of an elderly woman, who presented with incarcerated femoral hernia without signs of bowel obstruction. CT showed a femoral hernia with appendix in the femoral canal with signs of strangulation. the patient underwent emergency surgery. Diagnostic laparoscopy revelead a non-reducible appendix in the femoral canal, in the absence of signs of peritonitis. An infrainguinal incision was performed. An gangrenous appendix within the sac was revealed, detached from the sac and reintroduced into the abdomen through the femoral canal. The laparoscopic appendectomy was then performed. The hernia repair was performed by suturing the iliopubic tract to Cooper's ligament. Patient had a regular course. DISCUSSION: De Garengeot's hernia is a rare occurrence. After the year 2000 a total of 32articles, wich presented 34 cases of de Garengeot's hernia have been published. Due to the rarity of this disease there is not standard procedure; laparoscopy may be a valid technique for determining the condition of the hernia, but due to the difficulty of preoperative diagnosis it is unlikely to be the first choice for the surgical approach. The use of CT can therefore be decisive to help the surgeon in the choice of the approach. CONCLUSION: De Garengeot's hernia can be approached in urgent laparoscopy even in the complicated forms of appendicular inflammation. (www.actabiomedica.it).

BACKGROUND: The authors report a single-access transumbilical laparoscopic splenectomy (SATLS) performed with curved reusable instruments. METHODS: A 23-year-old female consulted for steroid-resistant idiopathic thrombocytopenic purpura and clinical evidence of secondary Cushing syndrome. Preoperative workup showed a normal-sized spleen and thrombocytopenia. The umbilicus was incised and a purse-string suture was applied. A reusable 11-mm trocar was inserted for a 10-mm, 30° angled scope. Curved reusable instruments (Karl Storz-Endoskope, Tuttlingen, Germany) were advanced without trocars transumbilically. After opening the splenocolic and gastrosplenic ligaments, the main splenic artery and vein were dissected off at the level of the hilum, clipped with 5-mm clips introduced transumbilically, and sectioned. Posterior splenic attachments were freed at the hilum cranially and caudally. The spleen was finally retrieved transumbilically in a plastic bag. RESULTS: Addition of supplementary trocars or incisions was not necessary. Operative time was 180 min and final umbilical scar 16 mm. The patient was discharged on postoperative day 3, and after 6 months she was doing well. CONCLUSIONS: SATLS was feasible and safe to be performed using curved reusable instruments. The curves of the instruments permitted the surgeon to work in an ergonomic position, without the instruments clashing thanks to the obtained triangulation. Since only reusable instruments were used, the cost of SATLS remained similar to that of standard laparoscopy.

BACKGROUND: The umbilicus can be considered as the embryological opening for single-access laparoscopic procedures. We report on single-access transumbilical laparoscopic appendectomy (SATLA) and cholecystectomy (SATLC), performed using new curved reusable instruments. PATIENTS AND METHODS: A retrospective review of a prospectively maintained database of 30 patients who underwent SATLA and 20 patients who underwent SATLC between May and November 2009 was undertaken. All procedures were performed with an 11-mm nondisposable trocar for the scope, and curved reusable instruments (Karl Storz-Endoskope, Tuttlingen, Germany) placed transumbilically without trocars. Outcome measures were conversion to standard laparoscopy, operative time, scar length, complications, hospital stay, and use of pain medication. RESULTS: All SATLA patients had acute appendicitis, and SATLC patients had symptomatic gallstones (15), chronic cholecystitis (3), and acute cholecystitis (2). No extraumbilical trocars were necessary. Mean total operative times were 57.3 ± 15.9 min (SATLA) and 73.9 ± 20.1 min (SATLC). Mean laparoscopic times were 39 ± 13.1 min (SATLA) and 57.5 ± 18.9 min (SATLC). Mean scar lengths were 14.8 ± 2.2 mm (SATLA) and 15.8 ± 2.3 mm (SATLC). Five SATLA patients and one SATLC patient developed postoperative complications. Mean hospital stay was 2.9 ± 1.3 days for SATLA patients and 1.8 ± 0.8 days for SATLC patients. Pain medication used was minimal. At the minimum follow-up of 3 months no late complications were registered. CONCLUSIONS: SATLA and SATLC can be performed safely using curved reusable instruments, which helps avoid the conflict between the surgeon's hands or between the instruments' tips and allows the surgeon to operate in an ergonomic position. The reusable instruments kept the cost similar to that of classic laparoscopy.

In recent years, laparoscopic surgery underwent a huge investment from both the clinical and research points of view to perform classic procedures through a single (S) incision or single port, resulting in the development of different instruments and ports. The main advantage of the S-access laparoscopy (SAL) is cosmesis. Future investigations will provide other potential advantages, such as improvement in postoperative pain and patient satisfaction. We report our initial experience on 115 patients utilizing a SAL (appendectomy, cholecystectomy, incisional hernia repair, Nissen fundoplication, upper gastrointestinal surgery, diagnostic laparoscopy, hepatic resection, splenectomy), along with the new curved reusable instruments (Karl Storz-Endoskope, Tuttlingen, Germany). The curves of the instruments enable the surgeon to work in an ergonomic position similar to classic laparoscopy, establishing a working triangulation inside the abdomen as well as outside. The cost of SAL is similar to classic laparoscopy as only reusable products are used.
