    (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.

    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.

    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.

    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.

    Esophagojejunal anastomotic fistula: a major issue after radical total gastrectomy
    (2019) BARCHI, Leandro Cardoso; RAMOS, Marcus Fernando Kodama Pertille; PEREIRA, Marina Alessandra; DIAS, Andre Roncon; RIBEIRO-JUNIOR, Ulysses; ZILBERSTEIN, Bruno; CECCONELLO, Ivan
    Gastric cancer surgery has evolved considerably over the past years, with substantial improvement on outcomes. Meanwhile, esophagojejunal anastomotic fistula (EJF) continues to impair postoperative results. This study aimed to assess EJF regarding its incidence, risk factors, management and the impact on overall survival. We retrospectively analyzed 258 consecutive patients who underwent total or completion gastrectomy for GC from 2009 and 2017. Clinicopathological characteristics analysis was performed comparing patients who developed EJF with patients with other clinical or surgical complications, as well as patients without any postoperative complications. Fifteen (5.8%) patients had EJF and 81 (31.4%) had other complications (including other surgical fistulas). The median time of EJF diagnosis was on the eighth postoperative day (range 3-76). Completion gastrectomy (p = 0.048) and longer hospital stay (p < 0.001) were associated with the occurrence of EJF. The surgical mortality of patients with EJF was higher than in non-EJF patients (26.7% vs. 4.5%; p < 0.001). Nine patients were treated conservatively and six required surgery. The mortality rate of EJF was 11.1% and 50% in patients who underwent conservative and surgical treatment, respectively. Patients with other complications and patients with EJF had worse survival compared to patients without any complication (p = 0.004 and p = 0.013, respectively). Completion gastrectomy is the main risk factor for EJF occurrence. Still, EJF is associated with high postoperative mortality, longer hospital stay and has a negative impact on long-term survival.

    CONVERSION THERAPY FOR GASTRIC CANCER: EXPANDING THE TREATMENT POSSIBILITIES
    (2019) RAMOS, Marcus Fernando Kodama Pertille; PEREIRA, Marina Alessandra; CHARRUF, Amir Zeide; DIAS, Andre Roncon; CASTRIA, Tiago Biachi de; BARCHI, Leandro Cardoso; RIBEIRO-JUNIOR, Ulysses; ZILBERSTEIN, Bruno; CECCONELLO, Ivan
    Background: Conversion therapy in gastric cancer (GC) is defined as the use of chemotherapy/radiotherapy followed by surgical resection with curative intent of a tumor that was prior considered unresectable or oncologically incurable. Aim: To evaluate the results of conversion therapy in the treatment of GC. Methods: Retrospective analysis of all GC surgeries between 2009 and 2018. Patients who received any therapy before surgery were further identified to define the conversion group. Results: Out of 1003 surgeries performed for GC, 113 cases underwent neoadjuvant treatment and 16 (1.6%) were considered as conversion therapy. The main indication for treatment was: T4b lesions (n = 10), lymph node metastasis (n = 4), peritoneal carcinomatosis and hepatic metastasis in one case each. The diagnosis was made by imaging in 14 cases (75%) and during surgical procedure in four (25%). The most commonly used chemotherapy regimens were XP and mFLOX. Major surgical complications occurred in four cases (25%) and one (6.3%) died. After an average follow-up of 20 months, 11 patients (68.7%) had recurrence and nine (56.3%) died. Prolonged recurrence-free survival over 40 months occurred in two cases. Conclusion: Conversion therapy may offer the possibility of prolonged survival for a group of GC patients initially considered beyond therapeutic possibility.

    Duodenal fistula: The most lethal surgical complication in a case series of radical gastrectomy
    (2018) RAMOS, Marcus Fernando Kodama Pertille; PEREIRA, Marina Alessandra; BARCHI, Leandro Cardoso; YAGI, Osmar Kenji; DIAS, Andre Roncon; SZOR, Daniel Jose; ZILBERSTEIN, Bruno; RIBEIRO-JUNIOR, Ulysses; CECCONELLO, Ivan
    Background: Despite all advances regarding the surgical treatment of gastric cancer (GC), duodenal stump fistula (DF) continues to negatively affect postoperative outcomes. This study aimed to assess DF regarding its incidence, risk factors, management and impact on overall survival. Methods: We retrospectively analyzed 562 consecutive patients who underwent gastrectomy for GC between 2009 and 2017. Clinicopathological characteristics analysis was performed comparing DF, other surgical fistulas and patients with uneventful postoperative course. Results: DF occurred in 15 (2.7%) cases, and 51 (9%) patients had other surgical fistulas. Tumor located in the lower third of the stomach (p=0.021) and subtotal gastrectomy (p=0.002) were associated with occurrence of DF. The overall mortality rate was 40% for DF and 15.7% for others surgical fistulas (p=0.043). The median time of DF onset was on postoperative day 9 (range 1-75). Conservative approach was performed in 8 patients and surgical intervention in 7 cases. Age (OR 7.41, p=0.012) and DF (OR 9.06, p=0.020) were found to be independent risk factors for surgical mortality. Furthermore, patients without fistula had better long-term survival outcomes comparing to patients with any type of fistulas (p=0.006). Conclusion: DF is related with distal tumors and patients submitted to subtotal gastrectomy. It affects not only the postoperative period with high morbidity and mortality rates, but may also have a negative impact on long-term survival.
