    (2020) BARCHI, Leandro Cardoso; RAMOS, Marcus Fernando Kodama Pertille; DIAS, Andre Roncon; ANDREOLLO, Nelson Adami; WESTON, Antonio Carlos; LOURENCO, Laercio Gomes; MALHEIROS, Carlos Alberto; KASSAB, Paulo; ZILBERSTEIN, Bruno
    Background: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated. Aim: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition. Methods: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers ""fully agree"" and ""partially agree"" was reached. This article presents only the responses of the participating experts. Comments on each statement, as well as a literature review, will be presented in future publications. Results: Of the 67 statements, there was consensus in 50 (74%). In 10 declarations, there was 100% agreement. Conclusion: The gastric cancer treatment has evolved considerably in recent years. This consensus gathers consolidated principles in the last decades, new knowledge acquired recently, as well as promising perspectives on the management of this disease.

    Robotic digestive tract reconstruction after total gastrectomy for gastric cancer: a simple way to do it
    (2016) BARCHI, Leandro Cardoso; JACOB, Carlos Eduardo; FRANCISS, Maurice Youssef; KAPPAZ, Guilherme Tommasi; RODRIGUES FILHO, Edison Dias; ZILBERSTEIN, Bruno
    Background Intracorporeal digestive tract reconstruction after minimally invasive total gastrectomy may be challenging, even when using the da Vinci (R) Surgical System. This may be due to intrinsic difficulties during oesophagojejunal anastomosis (EJA). The aim of this study was to describe a simple way to perform digestive tract reconstruction after robotic total gastrectomy (RTG) for gastric cancer and the results of its application in a small series of cases. Methods In the last 2 years, six patients with gastric adenocarcinoma have been treated by RTG, four male and two female, with mean age of 59.8 (range 48-74) years. The tumour was located in the gastric body in three patients, the gastric antrum in two patients and the fundus in one patient with no need of splenectomy. In all cases, D2 lymphadenectomy was completed. A modified robotic reconstruction technique proposed by the authors was used in these operations, which consists in a latero-lateral EJA using a linear stapler. An entero-enterostomy is also performed in the upper abdomen. Results The mean operative time was 408 (range 340-481) min. The mean time for digestive tract reconstruction was 57 (range 47-68) min. There were no conversions to open or laparoscopic surgery. The number of lymph nodes removed varied in the range 28-52 (average 40). There was no mortality. Postoperative staging showed three T1N0M0s, one T2N0M0, one T3N0M0 and one T3N2M0. Conclusion This series, which despite being small, demonstrates that this robotic reconstruction technique is safe, with no major complications, demands a relatively short time for its accomplishment, even when dealing with initial experience.

    GASTRIC NEUROENDOCRINE TUMOR: REVIEW AND UPDATE
    (2017) DIAS, Andre Roncon; AZEVEDO, Beatriz Camargo; ALBAN, Luciana Bastos Valente; YAGI, Osmar Kenji; RAMOS, Marcus Fernando Kodama Pertille; JACOB, Carlos Eduardo; BARCHI, Leandro Cardoso; CECCONELLO, Ivan; RIBEIRO-JR, Ulysses; ZILBERSTEIN, Bruno
    ABSTRACT Introduction: The frequency of gastric neuroendocrine tumors is increasing. Reasons are the popularization of endoscopy and its technical refinements. Despite this, they are still poorly understood and have complex management. Aim: Update the knowledge on gastric neuroendocrine tumor and expose the future perspectives on the diagnosis and treatment of this disease. Method: Literature review using the following databases: Medline/PubMed, Cochrane Library and SciELO. Search terms were: gastric carcinoid, gastric neuroendocrine tumor, treatment. From the selected articles, 38 were included in this review. Results: Gastric neuroendocrine tumors are classified in four clinical types. Correct identification of the clinical type and histological grade is fundamental, since treatment varies accordingly and defines survival. Conclusion: Gastric neuroendocrine tumors comprise different subtypes with distinct management and prognosis. Correct identification allows for a tailored therapy. Further studies will clarify the diseases biology and improve its treatment.

    Background: Standardized and transparent reporting of surgical technique is the cornerstone of effective dissemination, implementation and improvement. However, current reporting of surgical techniques is inadequate. The existing guidelines potentially applied to guide surgical technique reporting are with a minimal highlight of the surgical technique, lack requirements explaining what extent and dimensions need to be described in detail, or are unlikely to extrapolate to a wide range of surgical techniques. This study aims to formulate a rigorous protocol to develop a surgical technique reporting checklist and standards (SUPER) that defines what a clear, comprehensive and detailed surgical technique report should be contained. Methods: This protocol is designed following the classic guidance for developing reporting guidelines recommended by the EQUATOR network. Results: The development team will consist of surgeons (similar to 80%), methodologists, and journal editors. The draft checklist sources will include a scoping review of existing reporting guidelines related to surgical technique, surgical technique articles from 15 top journals published in the last year, and brainstorming by the multidisciplinary development team. The final SUPER checklist will be formed after three rounds of Delphi surveys, one round of face-to-face meeting, and a month-long pilot test. The SUPER checklist will be published as open-access and be used in combination with existing reporting guidelines related to surgical techniques (e.g., IDEAL). This protocol will steer the SUPER checklist's development, allowing us to further elaborate surgical technique reporting for all surgical specialties, and enabling a more favorable experience for surgeons, nurses, medical students, residents, editors, and reviewers.

    TOTAL OMENTECTOMY IN GASTRIC CANCER SURGERY: IS IT ALWAYS NECESSARY?
    (2019) BARCHI, Leandro Cardoso; RAMOS, Marcus Fernando Kodama Pertille; DIAS, Andre Roncon; YAGI, Osmar Kenji; RIBEIRO-JUNIOR, Ulysses; ZILBERSTEIN, Bruno; CECCONELLO, Ivan
    Background: Traditionally, total omentectomy is performed along with gastric resection and extended lymphadenectomy in gastric cancer (GC) surgery. However, solid evidences regarding its oncologic benefit is still scarce. Alm: To evaluate the incidence of metastatic omental lymph nodes (LN) in patients undergoing curative gastrectomy for GC, as well as its risk factors and patients' outcomes. Methods: All consecutive patients submitted to D2/modified D2 gastrectomy due to gastric adenocarcinoma from March 2009 to April 2016 were retrospectively reviewed from a prospective collected database. Results: Of 284 patients included, five (1.8%) patients had metastatic omental LN (one: pT3N3bM0; two: pT4aN3bM0; one: pT4aN2M0 and one pT4bN3bM0). Four of them deceased and one was under palliative chemotherapy due relapse. LN metastases in the greater omentum significantly correlated with tumor's size (p=0.018), N stage (p<0.001), clinical stage (p=0.022), venous invasion growth (p=0.003), recurrence (p=0.006), site of recurrence (peritoneum: p=0.008; liver: p=0.023; ovary: p=0.035) and death (p=0.008). Conclusion: The incidence of metastatic omental LN of patients undergoing radical gastrectomy due to GC is extremely low. Total omentectomy may be avoided in tumors smaller than 5.25 cm and T1/T2 tumors. However, the presence of lymph node metastases in the greater omentum is associated with recurrence in the peritoneum, liver, ovary and death.

    Simplified technique for reconstruction of the digestive tract after total and subtotal gastrectomy for gastric cancer
    (2014) ZILBERSTEIN, Bruno; JACOB, Carlos Eduardo; BARCHI, Leandro Cardoso; YAGI, Osmar Kenji; RIBEIRO-JR, Ulysses; COIMBRA, Brian Guilherme Monteiro Marta; CECCONELLO, Ivan
    BACKGROUND: Laparoscopic surgery has been increasingly applied to gastric cancer surgery. Gastrointestinal tract reconstruction totally done by laparoscopy also has been a challenge for those who developed this procedure. AIM - To describe simplified reconstruction after total or subtotal gastrectomy for gastric cancer by laparoscopy and the results of its application in a series of cases. METHODS - In the last four years, 75 patients were operated with gastric cancer and two with GIST. Thirty-four were women and 43 men. The age ranged from 38 to 77 years with an average of 55 years. In two patients with GIST a total and a subtotal gastrectomy were performed. In the other 75 patients were done 21 total gastrectomies and 54 subtotal. In all cancers, gastrectomy with D2 lymphadenectomy was completed with at least 37 lymph nodes removed. Was used in these operations a modified laparoscopic technique proposed by the authors consisting in a latero lateral esophagojejunal anastomosis with linear stapler in TG as well in STG, and reconstruction of the digestive continuity also in the upper abdomen. RESULTS - The intraoperative and immediate postoperative course were uneventful, except for one case of bleeding due to an opening clip, necessitating re-intervention. The operative time was 300 minutes, with no difference between total or subtotal gastrectomy. The number of lymph nodes removed varied from 28 to 69, averaging 37. Postoperative staging showed one case in T4 N2 M0; 13 in T2 N0 MO; 27 in T2 N1 M0; 24 in T3 N1 M0 and 10 in T3 N2 M0. Complication in only one case was observed on the 10th postoperative day with a small anastomotic leakage in esophagojejunal anastomose with spontaneous closure. CONCLUSION - The patient's evolution with no complications, no mortality and just one small anastomotic leakage with no systemic repercussions is a strong indication of the liability and feasibility of this innovative technical method.

    Gastric partitioning for the treatment of malignant gastric outlet obstruction
    (2019) RAMOS, Marcus Fernando Kodama Pertille; BARCHI, Leandro Cardoso; OLIVEIRA, Rodrigo Jose de; PEREIRA, Marina Alessandra; MUCERINO, Donato Roberto; RIBEIRO JR., Ulysses; ZILBERSTEIN, Bruno; CECCONELLO, Ivan
    BACKGROUND Gastric outlet obstruction (GOO) is one of the main complications in stage IV gastric cancer patients. This condition is usually managed by gastrojejunostomy (GJ). However, gastric partitioning (GP) has been described as an alternative to overcoming possible drawbacks of GJ, such as delayed gastric emptying and tumor bleeding. AIM To compare the outcomes of patients who underwent GP and GJ for malignant GOO. METHODS We retrospectively analyzed 60 patients who underwent palliative gastric bypass for unresectable distal gastric cancer with GOO from 2009 to 2018. Baseline clinicopathological characteristics including age, nutritional status, body mass index, and performance status were evaluated. Obstructive symptoms were graded according to GOO score (GOOS). Surgical outcomes evaluated included duration of the procedure, surgical complications, mortality, and length of hospital stay. Acceptance of oral diet after the procedure, weight gain, and overall survival were the long-term outcomes evaluated. RESULTS GP was performed in 30 patients and conventional GJ in the other 30 patients. The mean follow-up was 9.2 mo. Forty-nine (81.6%) patients died during that period. All variables were similar between groups, with the exception of worse performance status in GP patients. The mean operative time was higher in the GP group (161.2 vs 85.2 min, P < 0.001). There were no differences in postoperative complications and surgical mortality between groups. The median overall survival was 7 and 8.4 mo for the GP and GJ groups, respectively (P = 0.610). The oral acceptance of soft solids (GOOS 2) and low residue or full diet (GOOS 3) were reached by 28 (93.3%) GP patients and 22 (75.9%) GJ patients (P = 0.080). Multivariate analysis demonstrated that GOOS 2 and GOOS 3 were the main prognostic factors for survival (hazard ratio: 8.90, 95% confidence interval: 3.3823.43, P < 0.001). CONCLUSION GP is a safe and effective procedure to treat GOO. Compared to GJ, it provides similar surgical outcomes with a trend to better solid diet acceptance by patients.

    Development and Validation of a Nomogram for Early Detection of Malignant Gallbladder Lesions
    (2019) CHEN, Mingyu; CAO, Jiasheng; BAI, Yang; TONG, Chenhao; LIN, Jian; JINDAL, Vishal; BARCHI, Leandro Cardoso; NADALIN, Silvio; YANG, Sherry X.; PESCE, Antonio; PANARO, Fabrizio; ARICHE, Arie; KAI, Keita; MEMEO, Riccardo; BEKAII-SAAB, Tanios; CAI, Xiujun
    OBJECTIVES: Preoperative decision-making for differentiating malignant from benign lesions in the gallbladder remains challenging. We aimed to create a diagnostic nomogram to identify gallbladder cancer (GBC), especially for incidental GBC (IGBC), before surgical resection. METHODS: A total of 587 consecutive patients with pathologically confirmed gallbladder lesions from a hospital were randomly assigned to a training cohort (70%) and an internal validation cohort (30%), with 287 patients from other centers as an external validation cohort. Radiological features were developed by the least absolute shrinkage and selection operator logistic regression model. Significant radiological features and independent clinical factors, identified by multivariate analyses, were used to construct a nomogram. RESULTS: A diagnostic nomogram was established by age, CA19.9, and 6 radiological features. The values of area under the curve in the internal and external validation cohorts were up to 0.91 and 0.89, respectively. The calibration curves for probability of GBC showed optimal agreement between nomogram prediction and actual observation. Compared with previous methods, it demonstrated superior sensitivity (91.5%) and accuracy (85.1%) in the diagnosis of GBC. The accuracy using the nomogram was significantly higher in GBC groups compared with that by radiologists in the training cohort (P< 0.001) and similarly in each cohort. Notably, most of the IGBC, which were misdiagnosed as benign lesions, were successfully identified using this nomogram. DISCUSSION: A novel nomogram provides a powerful tool for detecting the presence of cancer in gallbladder masses, with an increase in accuracy and sensitivity. It demonstrates an unprecedented potential for IGBC identification.

    Minimally invasive surgery for gastric cancer in Brazil: current status and perspectives-a report from the Brazilian Laparoscopic Oncologic Gastrectomy Group (BLOGG)
    (2017) KASSAB, Paulo; COSTA JR., Wilson Luiz da; JACOB, Carlos Eduardo; CORDTS, Roberto de Moraes; CASTRO, Osvaldo Antonio Prado; BARCHI, Leandro Cardoso; CECCONELLO, Ivan; CHARRUF, Amir Zeide; COIMBRA, Felipe Jose Fernandez; CURY, Antonio Moris; DINIZ, Alessandro Landskron; FARIAS, Igor Correia de; FREITAS JR., Wilson Rodrigues de; GODOY, Andre Luis de; ILIAS, Elias Jirjoss; MALHEIROS, Carlos Alberto; RAMOS, Marcus Fernando Kodama Pertille; RIBEIRO, Heber Salvador de Castro; DIAS, Andre Roncon; THULER, Fabio Rodrigues; YAGI, Osmar Kenji; LOURENCO, Laercio Gomes; ZILBERSTEIN, Bruno
    The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG. After that there was a significant increase in that type of surgery, especially after the IRCAD opened a branch in Brazil. The growing interest for the subject led some services to begin their own experience with the LG and, since the beginning, the results were similar with those found in the open surgery. Nevertheless, there were some differences with the papers published initially in Japan and Korea. In those countries, the surgeries were laparoscopic assisted, meaning that, in the majority of cases, the anastomoses were done through a mini-incision in the end of the procedure. In Brazil since the beginning it was performed completely through laparoscopic approach due to the skills acquired by Brazilian surgeons in bariatric surgeries. Another difference was the stage. While in the east the majority of cases were done in T1 patients, in Brazil, probably due to the lack of early cases, the surgeries were done also in advanced cases. The initial experience of Zilberstein et al. revealed low rates of morbidity without mortality. Comparing laparoscopic and open surgery, the group from Barretos/IRCAD showed shorter surgical time (216x255 minutes), earlier oral or enteral feeding and earlier hospital discharge, with a smaller number of harvested lymph nodes (28 in laparoscopic against 33 in open surgery). There was no significant difference regarding morbidity, mortality and reoperation rate. In the first efforts to publish a multicentric study the Brazilian Gastric Cancer Association (BGCA) collected data from three institutions analyzing 148 patients operated from 2006 to 2016. There were 98 subtotal, 48 total and 2 proximal gastrectomies. The anastomoses were totally laparoscopic in 105, laparoscopic assisted in 21, cervical in 2, and 20 open (after conversion). The reconstruction methods were: 142 Roux-en-Y, two Billroth I, and three other types. The conversion rate was 13.5% (20/148). The D2 dissection was performed in 139 patients. The mean number of harvested lymph nodes was 34.4. If we take only the D2 cases the mean number was 39.5. The morbidity rate was 22.3%. The mortality was 2.7%. The stages were: IA-59, IB-14, IIA-11, IIB-15, IIIA-9, IIIB-19, IIIC-11 and stage IV-three cases. Four patients died from the disease and 10 are alive with disease. The participating services have already begun the robotic gastrectomy with satisfactory results. The intention of this group is to begin now a prospective multicentric study to confirm the data already obtained with the retrospective studies.
