| 2 | Role of one-step nucleic acid amplification in colorectal cancer lymph node metastases detection显示文摘Current histopathological staging procedures in colorectal cancer(CRC)depend on midline division of the lymph nodes(LNs)with one section of hematoxylin and eosin staining.Cancer cells outside this transection line may be missed,which could lead to understaging of Union for International Cancer Control Stage II high-risk patients.The one-step nucleic acid amplification(OSNA)assay has emerged as a rapid molecular diagnostic tool for LN metastases detection.It is a molecular technique that can analyze the entire LN tissue using a reversetranscriptase loop-mediated isothermal amplification reaction to detect tumorspecific cytokeratin 19 mRNA.Our findings suggest that the OSNA assay has a high diagnostic accuracy in detecting metastatic LNs in CRC and a high negative predictive value.OSNA is a standardized,observer-independent technique,which may lead to more accurate staging.It has been suggested that in stage II CRC,the upstaging can reach 25%and these patients can access postoperative adjuvant chemotherapy.Moreover,intraoperative OSNA sentinel node evaluation may allow early CRC to be treated with organ-preserving surgery,while in more advanced-stage disease,a tailored lymphadenectomy can be performed considering the presence of aberrant lymphatic drainage and skip metastases. | Francesco Crafa Serafino Vanella Onofrio A Catalano Kelsey L Pomykala Mario Baiamonte | 2022 | World Journal of Gastroenterology2022，28，30： | 0 |
| 3 | Non-exposed endoscopic wall-inversion surgery with one-step nucleic acid amplification for early gastrointestinal tumors:Personal experience and literature review显示文摘BACKGROUND Laparoscopic and endoscopic cooperative surgery is a safe,organ-sparing surgery that achieves full-thickness resection with adequate margins.Recent studies have demonstrated the safety and efficacy of these procedures.However,these techniques are limited by the exposure of the tumor and mucosa to the peritoneal cavity,which could lead to viable cancer cell seeding and the spillage of gastric juice or enteric liquids into the peritoneal cavity.Non-exposed endoscopic wallinversion surgery(NEWS)is highly accurate in determining the resection margins to prevent intraperitoneal contamination because the tumor is inverted into the visceral lumen instead of the peritoneal cavity.Accurate intraoperative assessment of the nodal status could allow stratification of the extent of resection.One-step nucleic acid amplification(OSNA)can provide a rapid method of evaluating nodal tissue,whilst nearinfrared laparoscopy together with indocyanine green can identify relevant nodal tissue intraoperatively.AIM To determine the safety and feasibility of NEWS in early gastric and colon cancers and of adding rapid intraoperative lymph node(LN)assessment with OSNA.METHODS The patient-based experiential portion of our investigations was conducted at the General and Oncological Surgery Unit of the St.Giuseppe Moscati Hospital(Avellino,Italy).Patients with early-stage gastric or colon cancer(diagnosed via endoscopy,endoscopic ultrasound,and computed tomography)were included.All lesions were treated by NEWS procedure with intraoperative OSNA assay between January 2022 and October 2022.LNs were examined intraoperatively with OSNA and postoperatively with conventional histology.We analyzed patient demographics,lesion features,histopathological diagnoses,R0 resection(negative margins)status,adverse events,and follow-up results.Data were collected prospectively and analyzed retrospectively.RESULTS A total of 10 patients(5 males and 5 females)with an average age of 70.4±4.5 years(range:62-78 years)were enrolled in this study.Five patients were diagnosed with gastric cancer.The remaining 5 patients were diagnosed with early-stage colon cancer.The mean tumor diameter was 23.8±11.6 mm(range:15-36 mm).The NEWS procedure was successful in all cases.The mean procedure time was 111.5±10.7 min(range:80-145 min).The OSNA assay revealed no LN metastases in any patients.Histologically complete resection(R0)was achieved in 9 patients(90.0%).There was no recurrence during the follow-up period.CONCLUSION NEWS combined with sentinel LN biopsy and OSNA assay is an effective and safe technique for the removal of selected early gastric and colon cancers in which it is not possible to adopt conventional endoscopic resection techniques.This procedure allows clinicians to acquire additional information on the LN status intraoperatively. | Francesco Crafa Serafino Vanella Aristide Morante Onofrio A Catalano Kelsey L Pomykala Mario Baiamonte Maria Godas Alexandra Antunes Joaquim Costa Pereira Valentina Giaccaglia | 2023 | World Journal of Gastroenterology2023，29，24： | 0 |
| 4 | Minimally invasive colorectal surgery learning curve显示文摘The learning curve in minimally invasive colorectal surgery is a constant subject of discussion in the literature.Discordant data likely reflects the varying degrees of each surgeon’s experience in colorectal,laparoscopic or robotic surgery.Several factors are necessary for a successful minimally invasive colorectal surgery training program,including:Compliance with oncological outcomes;dissection along the embryological planes;constant presence of an expert tutor;periodic discussion of the morbidity and mortality rate;and creation of a dedicated,expert team. | Serafino Vanella Enrico Coppola Bottazzi Giancarlo Farese Rosa Murano Adele Noviello Tommaso Palma Maria Godas Francesco Crafa | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，11： | 0 |
| 5 | Multimodal treatments of “gallstone cholangiopancreatitis”显示文摘Gallstone cholangiopancreatitis is a potentially life-threatening pathology which requires quick intervention involving endoscopists,interventional radiologists,anesthesiologists and surgeons in relation to clinical conditions.Treatment possibilities are varied,especially with current progress in advanced endoscopy,interventional radiology,and minimally invasive surgery.The following treatments are available:endoscopic sphincterotomy(ES)with stone extraction followed by laparoscopic cholecystectomy;simultaneous endoscopic stone extraction with laparoscopic cholecystectomy(rendezvous technique);combined laparoscopic cholecystectomy and common bile duct(CBD)exploration;open CBD exploration;ES post-cholecystectomy;percutaneous placement of biliary drains for unstable patients,followed by percutaneous cholangioscopy;and lithotripsy with different approaches,including a laser and balloon dilation of the sphincter of Oddi.Each technique has its strengths and weaknesses,and there is great discussion in the literature on choosing the ideal approach based on the patient’s clinical conditions. | Serafino Vanella Mario Baiamonte Francesco Crafa | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，7： | 0 |
| 6 | Laparoscopic and endoscopic cooperative surgery for full-thickness resection and sentinel node dissection for early gastric cancer显示文摘The endoscopic submucosal dissection(ESD)technique has become the gold standard for submucosal tumors that have negligible risk of lymph node metastasis(LNM),due to its minimal invasiveness and ability to improve quality of life.However,this technique is limited in stage T1 cancers that have a low risk of LNM.Endoscopic full thickness resection can be achieved with laparoscopic endoscopic cooperative surgery(LECS),which combines laparoscopic gastric wall resection and ESD.In LECS,the surgical margins from the tumor are clearly achieved while performing organ-preserving surgery.To overcome the limitation of classical LECS,namely the opening of the gastric wall during the procedure,which increases the risk of peritoneal tumor seeding,non-exposed endoscopic wall-inversion surgery was developed.With this full-thickness resection technique,contact between the intra-abdominal space and the intragastric space was eliminated. | Serafino Vanella Maria Godas Joaquim Costa Pereira Ana Pereira Ivano Apicella Francesco Crafa | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，8： | 0 |
