    Abstract Background: Surgical resection is the only curative option for gastric carcinoma (GC). Minimally invasive techniques are gaining popularity.
    Objectives: To present a single-surgeon's experience in transitioning from an open to a minimally invasive approach, focusing on surgical and oncological outcomes.
    Methods: We conducted a retrospective analysis including distal gastrectomy patients 2012-2020 operated by a single surgeon. Two cohorts were compared: open (ODG) and laparoscopic distal gastrectomy (LDG).
    Results: Overall, 173 patients were referred for gastrectomy during the study years. We excluded 80 patients because they presented with non-GC tumors, underwent proximal or total gastrectomy, or underwent palliative surgery. Neoadjuvant treatment was administered to 62 patients (33.3%). Billroth 1 was the preferred method of reconstruction (n=77, 82.8%), followed by Roux-en-Y (n=12, 13%). Fifty-one patients (54.8%) underwent LDG, 42 (45.2%) underwent ODG. The LDG group had significantly shorter lengths of stay (6 days, interquartile range [IQR] 1-3 5-8 vs. 5 days, IQR 1-3 4-6, P = 0.001, respectively), earlier return to oral feeding (1 day, IQR 1-3 1-3 vs. 2 days, IQR 1-3 1-3.2, P < 0.001), and earlier removal of drains (4 days, IQR 1-3 3-5.2 vs. 5 days, IQR 1-3 3.5-6.7, P < 0.001). Overall lymph node yield was 30 (IQR 1-3 24-39) and was similar among groups (P = 0.647).
    Conclusions: Laparoscopic techniques for resection of distal GC are feasible and safe, leading to good perioperative outcomes and adequate lymph node yield.

    Abstract Introduction: Inadvertent thoracic duct injury is common during esophagectomy and may result in postoperative chylothorax. This study's objective is to investigate utility of patent-blue injection as a modality for intraoperative thoracic duct visualization.
    Methods: A prospective, single-arm, interventional study of patients undergoing minimally invasive esophagectomy was performed. Patients were injected with patent-blue dye into both groins prior to thoracic stage of surgery and assessed for duct visualization. Control group was formed by propensity score matching using retrospectively collected data regarding patients who underwent esophagectomy.
    Results: A total of 25 patients were included in analysis, compared to a control of 50 patients after matching. Thoracic duct was visualized in 60% of patients in the study group (15/25 patients). Significant differences were found between study and control groups(p<0.05) with regards to median operative time (422 vs. 285 minutes, respectively), overall complications (16% vs. 34%, respectively) and median postoperative length of stay (13.5 vs. 10 days, respectively). There was a difference in rate of chyle leak between study and control groups, however this was not significant (0% vs. 12%, respectively, p=0.17).
    Conclusion: Patent-blue injection represents a simple method for thoracic duct visualization during minimally invasive esophagectomy which may improve surgical outcomes.

    Abstract Background: Esophagectomy is associated with significant perioperative morbidity. Limited data are available on the process of implementation of minimally invasive techniques in esophagectomy and related outcomes. The authors sought to describe implementation processes and outcomes following the implementation of the first minimally invasive esophagectomy (MIE) program at a high-volume center in Israel under the mentorship of American early adopters.
    Methods: Patients who underwent esophagectomy for esophageal carcinoma 2011-2022 were included. Early and late cohorts were created for learning curve analysis. Secondary analysis included patients who underwent open esophagectomy 1997-2011.
    Results: Overall, 300 patients underwent MIE: three-field MIE (3F-MIE) was performed in 242 (80.7%) patients, two-field MIE (2F-MIE) in 58 (19.3%) patients. Following program implementation in 2012, the number of MIE performed increased during the first 3 years ( n =33, 86.8% in 2015). Among 3F-MIE patients, a higher number of retrieved lymph nodes was reported during later cases (median, IQR1-3 17, 12-23 vs. 12, 8-12, P <0.001) while surgeries required a longer time (median, IQR1-3 300 min, 261-355 vs. 262.5, 239-300, P <0.001). Among 2F-MIE patients, the late cohort had lower rates of prolonged ICU admissions than earlier counterparts ( n =2, 6.9% vs. n =9, 31%, P =0.041), overall and severe 30-day complications ( n =12, 41.4% vs. n =23, 79.3%, P <0.001 and n =7, 24.1% vs. n =23, 79.3%, P =0.003).
    Conclusions: MIE was safely implemented. Nodal yield was higher among MIE patients than open esophagectomy. During the study years, open approach was gradually abandoned in favor of 3F-MIE procedures, while 2F-MIE increased over the course of the last years.

    Abstract Background: Favorable pathologic response(FPR) is a significant predictor for improved survival following Neoadjuvant therapy(NAT) in esophageal and gastroesophageal cancer(GEJ). Preoperative prediction of FPR could modify treatment plans. No reliable method for predicting FPR exists. We sought to identify preoperative predicting factors for FPR.
    Materials and methods: Retrospective analysis of patients with esophageal and GEJ cancer who underwent esophagectomy following (NAT). Univariate and multivariate analysis was used to identify preoperative predicting factors for FPR. A comparison of Tumor Regression Grade(TRG) was used to assess treatment response on overall survival(OS).
    Results: Out of 121 patients, 82(67.8%) had neoadjuvant chemoradiation. FPR was observed in 60(49.6%). Female sex, Radiation therapy(RT), squamous cell carcinoma(SCC), lack of signet ring feature, and FDG avidity posttreatment were associated with FPR on univariate analysis. RT and SCC were associated with FPR (OR=3.9 and 4.0, respectively) on multivariate analysis. OS was lower among patients who did not achieve FPR to NAT(P=0.027).
    Conclusions: FPR is a predictor of improved OS. SCC and radiation therapy-based protocol were identified as major prediction factors of FPR in patients with esophageal and GEJ cancers.

    Abstract Background: While the prognosis of patients with locoregional esophageal adenocarcinoma (EAC) has improved in the neoadjuvant treatment (NAT) era, high-grade histology (G3) is still associated with a limited treatment response. We sought to investigate oncologic outcomes in patients after esophagectomy for G3 EAC and to identify predictors of poor survival among these patients.
    Methods: Patients with EAC who underwent resection with curative intent in 2011-2018 were divided by histologic grade (G3, G1/2) and compared for overall survival (OS). Cox regression was performed to analyze the response to NAT and the predictive role of signet ring cell (SRC) features.
    Results: The cohort included 163 patients, 94 (57.7%) with G3 histology. NAT was administered to 69 (73.4%) patients. Following resection, OS in the G3 EAC group was 30 months (95% confidence interval [CI] 23.9-36.1). On univariate analysis, G3 disease (p = 0.050) and SRC features (p = 0.019) predicted low OS. Median survival in the G3 EAC group was worse in patients with SRC histology (18 months, 95% CI 8.6-27.4) than those without (30 months, 95% CI 23.8-36.1; p = 0.041). No patients with SRC histology were alive at 5 years of follow-up. Among all patients administered NAT, 88.2% of those with SRC showed minimal or no pathologic response and only 27.8% were downstaged.
    Conclusions: High-grade histology was found in most patients with EAC and predicted poor survival and treatment response. SRC features in patients with G3 disease were associated with lower OS. The benefit of NAT for G3 EAC in patients with SRC histology appears limited.

    Abstract Background: Left ventricular assist devices (LVADs) are used more commonly in patients with advanced-stage heart failure. Some of these patients may require elective or urgent abdominal surgical procedures.
    Objectives: To determine the outcomes of the management of LVAD-supported patients who underwent elective and urgent abdominal surgical procedures in our institution.
    Methods: A retrospective review was conducted on 93 patients who underwent LVAD implantation between August 2008 and January 2017. All abdominal surgeries in these patients were studied, and their impact on postoperative morbidity and mortality Ten patients underwent abdominal surgical procedures. Of these procedures, five were emergent and five were elective. The elective cases included one bariatric surgery for morbid obesity, one hiatal hernia repair, two cholecystectomies, and one small bowel resection for a carcinoid tumor. The emergency cases included suspected ischemic colitis, right colectomy for bleeding adenocarcinoma, laparotomy due to intraabdominal bleeding, open cholecystectomy for gangrenous cholecystitis, and laparotomy for sternal and abdominal wall infection. All patients undergoing elective procedures survived. Of the five patients who underwent emergency surgery, three died (60%, P = 0.16) and one presented with major morbidity. One of the two survivors required reintervention. In total, 12 interventions were performed on this group of patientswas evaluated.
    Results: Ten patients underwent abdominal surgical procedures. Of these procedures, five were emergent and five were elective. The elective cases included one bariatric surgery for morbid obesity, one hiatal hernia repair, two cholecystectomies, and one small bowel resection for a carcinoid tumor. The emergency cases included suspected ischemic colitis, right colectomy for bleeding adenocarcinoma, laparotomy due to intraabdominal bleeding, open cholecystectomy for gangrenous cholecystitis, and laparotomy for sternal and abdominal wall infection. All patients undergoing elective procedures survived. Of the five patients who underwent emergency surgery, three died (60%, P = 0.16) and one presented with major morbidity. One of the two survivors required reintervention. In total, 12 interventions were performed on this group of patients.
    Conclusions: It is safe to perform elective abdominal procedures for LVAD-supported patients. The prognosis of these patients undergoing emergency surgery is poor and has high mortality and morbidity rates.

    Abstract Background: Surgical resection is considered to be the best treatment for gastrointestinal stromal tumor (GIST), the most common mesenchymal tumor of the gastrointestinal tract. Tumor size, mitotic rate, and anatomic locations are directly related to the potential malignancy, surgical approach, oncological treatment, and recurrence rate.
    Materials and methods: This was a retrospective study of 40 patients who underwent surgical resection of histologically or immunohistochemistry-proven GIST of the stomach at the Rabin and Kaplan Medical Center between 2004 and 2013. Tumor size, location, margin status, pathologic characteristics, surgical approach, surgical outcome, and long-term follow-up were analyzed from hospital records.
    Results: The most common presentation was upper gastrointestinal bleeding (40%), although 30% of cases were asymptomatic. A laparoscopic approach was the preferred technique whenever feasible; 85% of tumors were localized in the proximal stomach, with a median size of 5.6 cm. Most of the resected tumors revealed a low mitotic rate and thus had low-moderate risks of malignancy. All tumors were completely resected with free surgical margins. The median follow-up period was 40 months with 93% disease-free survival.
    Conclusions: Gastric GIST is a snake in the grass and its diagnosis is often incidental to endoscopy and computed tomographic scan. The most important technical point is to avoid tumor rupture during removal.
