RESUMO

INTRODUCTION: This study evaluates surgical outcomes of minimally invasive Ivor Lewis esophagectomy (ILE) for esophageal and esophagogastric cancer, with the comparison of the robotic approach (RA) and the conventional minimally invasive approach (CA). METHODS: Selected patients who underwent minimally invasive ILE for esophageal cancer were included between January 2017 and December 2023. We retrospectively investigated the patients' background characteristics and the short-term surgical outcomes. RESULTS: In this period, among a total of 840 esophagectomies, 81 patients (9.6%) underwent minimally invasive ILE, consisting of 24 cases with RA and 57 with CA. The major indications for ILE were adenocarcinoma of the distal esophagus or esophagogastric junction and patients with prior head and neck cancer treatment. Among these thoracic approaches, there were no significant differences in the patients' indications and characteristics, including age, histology, tumor location, clinical TNM stage, and preoperative therapy. Compared with the CA group, no anastomotic leakage was observed in the RA group (17.5% vs. 0, p = .035). Rates of total postoperative complications and length of hospital stay also tended to be reduced in the RA group but did not reach significance. CONCLUSION: In the Ivor Lewis esophagectomy with a side-to-side linear-stapled anastomosis, the fully robotic approach has the potential to powerfully reduce anastomotic leakage compared to the conventional minimally invasive approach.

RESUMO

BACKGROUND: Robotic surgical systems with full articulation of instruments, tremor filtering, and motion scaling can potentially overcome the procedural difficulties in endoscopic surgeries. However, whether robot-assisted minimally invasive esophagectomy (RAMIE) can overcome anatomical difficulties during thoracoscopic esophagectomy remains unclear. This study aimed to clarify the anatomical and clinical factors that influence the difficulty of RAMIE in the thoracic region. METHODS: Forty-five patients who underwent curative-intent RAMIE with upper mediastinal lymph node dissection for esophageal cancer were included. Using preoperative computed tomography images, we calculated previously reported anatomical indices to assess the upper mediastinal narrowness and vertebral body projections in the middle thoracic region. The factors influencing thoracic operative time were then investigated. RESULTS: During the thoracic procedure, the median operative time was 215 (124-367) min and the median blood loss was 20 (5-190) mL. Postoperatively, pneumonia, anastomotic leakage, and recurrent laryngeal nerve palsy occurred in 17.8%, 2.2%, and 6.7% of the patients, respectively. The multiple linear regression model revealed that a narrow upper mediastinum and greater blood loss during the thoracic procedure were significant factors associated with a prolonged thoracic operative time (P = 0.025 and P < 0.001, respectively). Upper mediastinal narrowing was not associated with postoperative complications. CONCLUSIONS: A narrow upper mediastinum was significantly associated with a prolonged thoracic operative time in patients with RAMIE.

RESUMO

BACKGROUND: Minimally invasive esophagectomy (MIE) has been increasingly performed for locally advanced esophageal cancer in place of open transthoracic esophagectomy (OE). This study explored the significance of MIE for esophageal squamous cell carcinoma (ESCC), focusing mainly on the depth of primary esophageal tumors. METHODS: This study retrospectively assessed short- and long-term outcomes of patients who underwent esophagectomy for ESCC from 2005 through 2021. The inverse probability of the treatment-weighting (IPTW) method was used to compare the outcomes between OE and MIE. The outcomes also were evaluated in the subgroups stratified by cT category. RESULTS: Among 1117 patients, 447 (40%) underwent OE and 670 (60%) underwent MIE. After IPTW adjustment, the incidence of any postoperative complications was significantly higher in the OE group than in the MIE group (60.8% vs 53.7%; p = 0.032), whereas the R0 resection rate was significantly higher in the MIE group (98.6% vs 92.7%; p < 0.001). The MIE group showed better 3 year overall and cancer-specific survival than the OE group (p < 0.001). The incidence of locoregional recurrence within the surgical field was significantly more frequent in the OE group (p < 0.001). In the subgroup analysis stratified by cT category, the R0 resection rate was significantly higher and the incidence of locoregional recurrence was lower in the MIE group among the patients with cT3-4 tumors. In the patients with cT1-2 tumors, MIE showed no significant benefit over OE. CONCLUSIONS: For the patients with cT3-4 tumors, MIE showed fewer postoperative complications, better locoregional control, and better prognosis than OE. Compared with OE, MIE is beneficial, especially for locally advanced ESCC.

RESUMO

A high risk of complications still accompanies gastric conduit reconstruction after esophagectomy. In this narrative review, we summarize the technological progress and the problems of gastric conduit reconstruction after esophagectomy. Several types of gastric conduits exist, including the whole stomach and the narrow gastric tube. The clinical outcomes are similar between the two types of conduits. Sufficient blood supply to the conduit is mandatory for a successful esophageal reconstruction. Recently, due to the availability of equipment and its convenience, indocyanine green angiography has been rapidly spreading. When the blood perfusion of the planning anastomotic site is insufficient, several techniques, such as the Kocher maneuver, pedunculated gastric tube with duodenal transection, and additional microvascular anastomosis, exist to decrease the risk of anastomotic failure. There are two different anastomotic sites, cervical and thoracic, and mainly two reconstructive routes, retrosternal and posterior mediastinal routes. Meta-analyses showed no significant difference in outcomes between the anastomotic sites as well as the reconstructive routes. Anastomotic techniques include hand-sewn, circular, and linear stapling. Anastomoses using linear stapling is advantageous in decreasing anastomosis-related complications. Arteriosclerosis and poorly controlled diabetes are the risk factors for anastomotic leakage, while a narrow upper mediastinal space and a damaged stomach predict leakage. Although standardization among the institutional team members is essential to decrease anastomotic complications, surgeons should learn several technical options for predictable or unpredictable intraoperative situations.

RESUMO

BACKGROUND: Increased serum cortisol (COR) concentrations may induce glucocorticoid resistance by down-regulation of glucocorticoid receptor (GCR), resulting in decreased chemotherapy efficacy in dogs with lymphoma. HYPOTHESIS: Investigate the relationship between serum COR concentrations and chemotherapy outcomes in dogs with lymphoma. ANIMALS: Thirty client-owned dogs with lymphoma, with serum COR concentration measured using serum samples collected at diagnosis. METHODS: Retrospective study. Dogs were divided into 2 groups based on serum COR concentrations: a normal group (n = 16) with COR concentrations <6 µg/dL and a high group (14) with COR concentrations ≥6 µg/dL. We compared signalment, clinical signs, stage, type of lymphoma, adrenal gland size, alkaline phosphatase (ALP) activity, response to chemotherapy, progression-free survival (PFS), overall survival (OS), and rate of P-glycoprotein (P-gp)- and GCR-positive cells between the 2 groups. RESULTS: No significant differences were found in the demographic characteristics between the 2 groups. However, the high COR group exhibited a significantly lower response to chemotherapy, PFS, and OS compared with the normal COR group. Serum ALP activity was significantly higher in the high COR group than in the normal COR group. Adrenal gland size was also significantly larger in the high COR group. Although no significant differences were found in the rate of P-gp-positive cells between the 2 groups, the rate of GCR-positive cells was significantly lower in the high COR group. CONCLUSIONS AND CLINICAL IMPORTANCE: Our data suggests that measurement of serum COR concentrations may serve as a potential prognostic factor and evaluation index.

RESUMO

This study aimed to determine the prevalence and risk factors of poor subjective sleep quality in elite judo athletes. A subjective cross-sectional questionnaire survey was conducted with 106 elite judo athletes who participated in the training camp of the Japanese national team. Eighty-six respondents (men: 52.3%; average age: 22.9 ± 3.1 years) with complete responses were included in the analysis (valid response rate: 81.1%). Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). The prevalence of poor sleep quality (PSQI score ≥ 5.5), the mean PSQI score, and subscale scores were investigated. Relationships between poor sleep quality and attributes, lifestyle habits, competition-based activities, and psychological distress were explored using Fisher's exact tests and multivariate logistic regression analysis. Thirty-five respondents (40.7%) reported poor sleep quality. The percentage and subscale scores of the respondents for sleep latency, sleep duration, and daytime dysfunction were higher than those of the population of Japanese national-level athletes. The mean PSQI score of the respondents was similar to that of some elite athlete populations but higher than those of others. Multivariate logistic regression analysis revealed that psychological distress was associated with poor sleep quality. In conclusion, the prevalence of poor subjective sleep quality in elite judo athletes was suggested to be similar or higher among elite athlete population. Sleep latency, sleep duration, and daytime dysfunction status were worse in elite judo athletes than in Japanese national-level athletes. Psychological distress was a risk factor for poor subjective sleep quality in elite judo athletes.
