ABSTRACT
INTRODUCTION: Reported rates of subcarinal lymph node (LN) metastases for esophageal carcinoma vary from 20% to 25% and the relevance of subcarinal lymph node dissection (LND) for gastroesophageal junction (GEJ) adenocarcinoma is poorly defined. This study aimed to evaluate rates of subcarinal LN metastasis in GEJ carcinoma and determine their prognostic significance. METHODS: Patients with GEJ adenocarcinoma undergoing robotic minimally invasive esophagectomy from 2019 to 2021 were retrospectively assessed within a prospectively maintained database. Baseline characteristics and outcomes were examined with attention to subcarinal LND and LN metastases. RESULTS: Among 53 consecutive patients, the median age was 62, 83.0% were male, and all had Siewert type I/II tumors (49.1% and 50.9%, respectively). Most patients (79.2%) received neoadjuvant therapy. Three patients had subcarinal LN metastases (5.7%) and all had Siewert type I tumors. Two had clinical evidence of LN metastases preoperatively and all three additionally had non-subcarinal nodal disease. A greater proportion of patients with subcarinal LN disease had more advanced (T3) tumors compared to patients without subcarinal metastases (100.0% versus 26.0%; P = 0.025). No patient with subcarinal nodal metastases remained disease free at 3 y after surgery. CONCLUSIONS: In this consecutive series of patients with GEJ adenocarcinoma undergoing minimally invasive esophagectomy, subcarinal LN metastases were found only in patients with type I tumors and were noted in just 5.7% of patients, which is lower than historical controls. Subcarinal nodal disease was associated with more advanced primary tumors. Further study is warranted to determine the relevance of routine subcarinal LND, especially for type 2 tumors.

Despite decreasing overall morbidity with minimally invasive esophagectomy (MIE), conduit functional outcomes related to delayed emptying remain challenging, especially in the immediate postoperative setting. Yet, this problem has not been described well in the literature. Utilizing a single institutional prospective database, 254 patients who underwent MIEs between 2012 and 2020 were identified. Gastric conduit dilation was defined as a conduit occupying >40% of the hemithorax on the postoperative chest X-ray. Sixty-seven patients (26.4%) demonstrated acute conduit dilation. There was a higher incidence of conduit dilation in the patients who underwent Ivor Lewis esophagectomy compared to those with a neck anastomosis (67.2% vs. 47.1%; P = 0.03). Patients with dilated conduits required more esophagogastroduodenoscopies (EGD) (P < 0.001), conduit-related reoperations within 180 days (P < 0.001), and 90-day readmissions (P = 0.01). Furthermore, in 37 patients (25.5%) undergoing Ivor Lewis esophagectomy, we returned to the abdomen after intrathoracic anastomosis to reduce redundant conduit and pexy the conduit to the crura. While conduit dilation rates were similar, those who had intraabdominal gastropexy required EGD significantly less and trended toward a lower incidence of conduit-related reoperations (5.6% vs. 2.7%). Multivariable analysis also demonstrated that conduit dilation was an independent predictor for delayed gastric conduit emptying symptoms, EGD within 90 days, conduit-related reoperation within 180 days, and 30-day as well as 90-day readmission. Patients undergoing MIE with acute gastric conduit dilation require more endoscopic interventions and reoperations.

Minimally invasive esophagectomy (MIE) is becoming more widespread with a documented improvement in postoperative morbidity based on level I evidence. However, there is a lack of consensus regarding the optimal MIE approach, conventional thoracoscopy/laparoscopy vs robotics as well as the ideal anastomotic technique. All patients who underwent MIE via an Ivor Lewis approach with a side-to-side stapled anastomosis were included. The thoracoscopy-laparoscopy (TL) group was compared to the robotic group with respect to perioperative outcomes using the entire cohorts and after 1:1 propensity score matching. Comparisons were made using the Mann-Whitney U and Fisher's exact tests. Between July 2013 and November 2020, 72 TL and 67 robotic Ivor Lewis MIE were performed. After comparing the two unadjusted cohorts and 51 propensity matched pairs, there was a decrease in Clavien-Dindo Grade 2 or above complications in the robotic vs TL group (59.7% vs 41.8% [P = 0.042], (62.7% vs 39.2% [P = 0.029]), respectively. In both analyses, there was a reduction in hospital length of stay (median of 8 vs 7 days, P < 0.001) and a trend toward less anastomotic leaks in the robotic group (Unadjusted: 12.5 vs 3% [P = 0.057], Propensity-matched analysis: 13.7% vs 3.9% [P = 0.16]), respectively. A clinically significant decrease in overall morbidity, cardiac complications and hospital length of stay was observed in the robotic Ivor Lewis cohort when compared with the TL group at a high volume MIE program. Side-to-side stapled thoracic anastomoses utilizing a robotic platform provides the best outcomes in this single institution experience.

In this multimedia article, we demonstrate transabdominal robotic enucleation of a large, multilobulated leiomyoma at the gastroesophageal junction (GEJ). The robotic platform provides stereoscopic visualization and wristed motion, which improved ease of an organ-sparing resection in a challenging anatomic location. Alternative minimally invasive approaches to tumors in this location have been reported including endoscopic, endoscopic with laparoscopic assistance, laparoscopic, and thoracoscopic approaches, with choice of approach dependent upon the location and configuration of the tumor Milito et al. in J Gastrointest Surg 24:499-504, 2020;Li et al. in Dis Esophagus. 22:185-189, 2009;Armstrong et al. in Am Surg. 79:968-972, 2013;Kent et al. in J Thorac Cardiovasc Surg. 134:176-181, 2007.

BACKGROUND: Few studies have compared the survival advantage of complete pathologic response (cPR) achieved through neoadjuvant chemotherapy (nCT) versus neoadjuvant chemoradiotherapy (nCRT) in gastric adenocarcinoma. Our study utilizes a large national cancer database to address this question. PATIENTS AND METHODS: This is a retrospective review of patients with clinical stage I to III gastric adenocarcinoma from 2004 to 2013 who received nCT or nCRT. Patients who achieved cPR were selected. Associations were evaluated using Mann-Whitney U and Fisher's exact tests. Survival information was summarized using standard Kaplan-Meier methods, where estimates of the median and 5-year survival rates were estimated with 95% confidence intervals. RESULTS: A total of 413 patients who had cPR were identified. Eighty-four patients received nCT and 329 patients received nCRT. Patients in the nCRT group had higher clinical stage (88.4% vs. 75.0%) and more proximal location of tumors (95.4% vs. 45.2%). The nCT group (n = 84) had a 94% 5-year survival rate, while the nCRT group's (n = 329) rate was 60% (p < 0.001). On Cox regression modeling using a propensity-weighted approach, nCT treatment was an independent predictor of improved overall survival (nCRT vs. nCT; HR 10.44, p < 0.001). CONCLUSIONS: The use of nCT leads to a significant increase in overall survival in patients when compared with nCRT for those who achieved cPR in gastric adenocarcinoma. While this study is limited in identifying the cause for this difference in overall survival, this important finding nonetheless requires further investigation and should be considered in the development of future gastric cancer trials.

BACKGROUND AND OBJECTIVES: Pasireotide was shown in a randomized trial to decrease the rate of postoperative pancreatic fistula (POPF). However, retrospective series from other centers have failed to confirm these results. METHODS: Patients who underwent pancreatoduodenectomy or distal pancreatectomy between January 2014 and February 2019 were included. Patients treated after November 2016 routinely received pasireotide and were compared to a retrospective cohort. Multivariate analysis was performed for the outcome of clinically relevant POPF (CR-POPF), with stratification by fistula risk score (FRS). RESULTS: Ninety-nine of 300 patients received pasireotide. The distribution of high, intermediate, low, and negligible risk patients by FRS was comparable (P = .487). There were similar rates of CR-POPF (19.2% pasireotide vs 14.9% control, P = .347) and percutaneous drainage (12.1% vs 10.0%, P = .567), with greater median number of drain days in the pasireotide group (6 vs 4 days, P < .001). Multivariate modeling for CR-POPF showed no correlation with operation or pasireotide use. Adjustment with propensity weighted models for high (OR, 1.02, 95% CI, 0.45-2.29) and intermediate (OR, 1.02, CI, 0.57-1.81) risk groups showed no correlation of pasireotide with reduction in CR-POPF. CONCLUSIONS: Pasireotide administration after pancreatectomy was not associated with a decrease in CR-POPF, even when patients were stratified by FRS.

BACKGROUND: The purpose of this study was to determine whether neoadjuvant and/or perioperative chemotherapy (NAC) has an overall survival (OS) benefit for patients with T2N0 gastric adenocarcinoma. STUDY DESIGN: We performed retrospective analyses using the National Cancer Data Base, 2004-2013. Patients with T2N0 gastric adenocarcinoma were divided into two treatment groups: (1) NAC plus surgery (NA + S) and (2) surgery alone (S). RESULTS: Of 1,704 patients included, 277 (16.3%) received NAC, and 1,427 (83.7%) were treated with surgery alone. Patients in the NA + S group were more likely to be younger, have fewer comorbidities, and have larger tumors located in the proximal stomach. Although in an unadjusted analysis of OS, the NA + S group had improved survival compared to the S group (HR = 0.81, 95% CI 0.67-0.99, P < 0.0001), this was not maintained in a propensity adjusted analysis (HR = 0.89, 95% CI 0.68-1.18, P = 0.42). Similarly, propensity adjusted analyses accounting for potential bias from clinical misstaging or treatment effect from NAC did not show any OS benefit from NAC. CONCLUSION: Based on the largest cohort of clinically staged T2N0 gastric adenocarcinoma, there was no OS benefit derived from NAC compared to surgery alone. For select patients with reliable preoperative staging, NAC may be omitted.

BACKGROUND: Surgical resection remains the mainstay of treatment for tumors of the gastroesophageal junction (GEJ). However, contemporary analyses of the Western experience for GEJ adenocarcinoma are sparsely reported. METHODS: Patients with GEJ adenocarcinoma undergoing resection between 2012 and 2022 at a single institution were grouped based on Siewert subtype and analyzed. Pathologic and treatment related variables were assessed with relation to outcomes. RESULTS: A total of 302 patients underwent resection: 161 (53.3%) with type I, 116 (38.4%) with type II, and 25 (8.3%) with type III tumors. Most patients received neoadjuvant therapy (86.4%); 86% of cases were performed in a minimally invasive fashion. Anastomotic leak occurred in 6.0% and 30-day mortality in only 0.7%. The rate of grade 3+ morbidity was lower for the last 5 years of the study than for the first 5 years (27.5% vs 49.3%, P < .001), as was median length of stay (7 vs 8 days, P < .001). There was a significantly greater number of signet ring type tumors among type III tumors (44.0%) than type I/II tumors (11.2/12.9%, P < .001). Otherwise, there was no difference in the distribution of pathologic features among Siewert subtypes. Notably, there was a significant difference in 3-year overall survival based on Siewert classification: type I 60.0%, type II 77.2%, and type III 86.3% (P = .011). Siewert type I remained independently associated with worse survival on multivariable analysis (hazard ratio, 4.5; P = .023). CONCLUSIONS: In this large, single-institutional series, operative outcomes for patients with resected GEJ adenocarcinoma improved over time. On multivariable analysis, type I tumors were an independent predictor of poor survival.

The incidence of bilateral adrenal hemorrhage (BAH) in the postoperative setting is rare, but potentially life threatening. A literature review of postoperative BAH reveals that there is limited data on BAH following abdominal surgery. We present a case of BAH following pancreaticoduodenectomy, which has not been previously documented in the literature. A 70-year-old male patient with no previous history of adrenal disease underwent an uncomplicated pancreaticoduodenectomy and was discharged after a typical postoperative course. He was readmitted with abdominal pain and ileus on POD 8 and a computed tomography (CT) scan was initially unremarkable, but a repeat CT scan on POD 11 demonstrated BAH. He was found to have adrenal insufficiency and was successfully treated with steroids. Clinicians should be aware of the possibility of adrenal hemorrhage postoperatively as it can potentially be a fatal surgical complication. To enhance patient outcomes, early detection and appropriate treatment are essential.
ABSTRACT
OBJECTIVES: Patients with diabetes are at particularly high risk for adverse outcomes after hospitalization. The goals of this study were to design, implement, and evaluate a multipronged transitional care intervention among hospitalized patients with diabetes. METHODS: We randomly assigned inpatients likely to be discharged home on insulin to an intensive transitional care intervention or usual care. The primary outcome was 90-day postdischarge insulin adherence, using prescription refill information to calculate a medication possession ratio. Unadjusted analyses were conducted using Wilcoxon rank sum; adjusted analyses used multivariable linear regression and weighted propensity scoring methods, with general estimating equations to account for clustering by admitting physician. RESULTS: One hundred eighty patients participated. The mean (SD) medication possession ratio to all insulin types was 84.5% (22.6) among intervention and 76.4% (25.1) among usual care patients (difference = 8.1, 95% confidence interval = -1.0 to 17.2, P = 0.06), with a smaller difference for adherence to all medications (86.3% versus 82.0%). A1c levels decreased in both groups but was larger in the intervention arm (1.09 and 0.11, respectively) (difference = -0.98, 95% confidence interval = -2.03 to -0.07, P = 0.04). Differences between study arms were not significant for rates of hypoglycemic episodes, 30-day readmissions, or emergency department visits. In adjusted/clustered analyses, the difference in A1c reduction remained statistically significant, whereas differences in all other outcomes remained nonsignificant. CONCLUSIONS: The intervention was associated with improvements in glycemic control, with nonsignificant trends toward greater medication adherence. Further research is needed to optimize and successfully implement interventions to improve patient safety and health outcomes during care transitions.

BACKGROUND: Gastric schwannomas are uncommon among a broad range of possible diagnoses in the work up of a gastric mass. Regional lymphadenopathy associated with gastric schwannoma is an even less common occurrence and one would otherwise suspect a malignant neoplasm. CASE PRESENTATION: We present two non-consecutive cases from a signle academic center depicting Caucasian females in their 5th and 6th decades of life with gastric schwannoma and adjacent lymphadenopathy. Multiple lymph node excisions were performed without evidence of neoplasia. DISCUSSION: Lymphadanopathy in the presence of a gastric mass typically represents malignant neoplasm. A less than likely presentation of gastric schwannoma with reactive regional lymph nodes poses a challenge to adequate preoperative diagnosis and increases risk for a more aggressive than necessary surgical approach with lymphadenectomy. CONCLUSION: While the correlation between gastric schwannoma and lymphadenopathy is uncertain, this ought to be considered. If diagnosis can be confirmed preoperatively, omission of lymphadenectomy is appropriate.
