    <p>Background: Laparoscopic wedge resection (LWR) is widely performed for managing gastric submucosal tumors (SMTs). Despite the development of novel procedures such as laparoscopy–endoscopy cooperative surgery (LECS) and nonexposed endoscopic wall-inversion surgery (NEWS), the most appropriate surgical intervention for gastric SMTs remains unclear. Methods: We retrospectively reviewed patient characteristics, surgical outcomes, postoperative courses, results of histopathological examinations, and surgical costs of 71 consecutive patients who underwent LWR, LECS, or NEWS for gastric SMTs from January 2010 to June 2016 in our institute. Results: LWR, LECS, and NEWS were performed in 31, 14, and 26 cases, respectively. Patient backgrounds were comparable between groups. LWR was not performed for esophagogastric (E–G) junction tumors to avoid postoperative stricture, and LECS was not performed for ulcerated tumors to prevent tumor dissemination. NEWS was considered for tumors smaller than 3 cm for transoral extraction. Resected specimen area of the LWR group was significantly larger than that of the other groups. Further, the LWR group had a significantly higher complication rate. Compared to the LECS group, postoperative serum C-reactive protein level was significantly lower and postoperative hospitalization was significantly shorter in the NEWS group. Also, operation costs were significantly lower in the NEWS group. Conclusions: The surgical procedure for gastric SMTs must be carefully chosen according to tumor size, location, and presence or absence of ulceration. For selected patients, NEWS is suggested to be an appropriate option for the treatment of gastric SMTs.</p>

  • Prognostic Impact of Change in the Fibrinogen and Albumin Score During Preoperative Treatment in Esophageal Cancer Patients

    <p>Background: For resectable advanced esophageal cancer, a transthoracic esophagectomy following preoperative treatment is recognized as one of the standard treatments. Therefore, predictive markers which can be identified before surgery need to be established to identify patients with a poor prognosis. Methods: We retrospectively reviewed 102 consecutive patients who underwent curative transthoracic esophagectomy following preoperative treatment in our institution between 2004 and 2013. Based on plasma fibrinogen and serum albumin levels, the pretreatment and preoperative fibrinogen and albumin score (FA score) were investigated and the prognostic significance of the FA score change was compared with RECIST. Results: The patients were classified according to whether the FA score had remained unchanged or decreased (n = 77) or the FA score increased (n = 25). When the correlation between the response rate and change in the FA score was investigated, the response rate was significantly lower in the group with the increased FA score. In the survival analysis, patients in the increased FA score group exhibited a significantly worse recurrence-free survival (RFS) (P = 0.038). A multivariate analysis using the clinical stage and the change in the FA score as covariates revealed that a change in the FA score (HR 1.802; P = 0.047; 95% CI 1.008–3.221) was shown to be a significant independent predictive factor for RFS. Conclusions: A change in the FA score was shown to be an independent prognostic factor for postoperative recurrence in esophageal cancer patients who have undergone transthoracic esophagectomy following preoperative treatment.</p>

    <p>Objective and design: An animal experiment was performed to demonstrate the anti-inflammatory effects of an alpha-lipoic acid (ALA) derivative, dihydrolipoyl histidinate zinc complex (DHLHZn) for acute lung injury (ALI) and to investigate the mechanism of action. Material: Rats were randomly divided into three experimental groups: control group (n = 17), DHLHZn(−) group (n = 11, ALI model rats), and DHLHZn(+) group (n = 12, ALI model rats treated by DHLHZn). Treatment: Lipopolysaccharides (LPS, 10 mg/kg) were administered intratracheally in the DHLHZn(−) group and the DHLHZn(+) group. For the DHLHZn(+) group, DHLHZn (100 mg/kg) was administered intraperitoneally 2 h prior to LPS administration. Methods: Four hours after LPS administration, bronchoalveolar lavage fluid (BALF) and lung tissue were collected. The findings were analyzed using the Mann–Whitney U test. Results: Total number of cells, number of neutrophils and lymphocytes, levels of various inflammatory cytokines, and NF-kB p65 concentration of BALF were significantly lower in the DHLHZn(+) group than in the DHLHZn(−) group (p &lt; 0.05). ALI pathology scores were significantly lower in the DHLHZn(+) group than in the DHLHZn(−) group (p &lt; 0.001). Conclusions: Anti-inflammatory effects of DHLHZn for ALI were demonstrated by BALF and histopathological findings. The mechanism of action of DHLHZn was considered to be via inhibition of the NF-kB signaling pathway. DHLHZn is thus suggested to be a new prophylactic agent for ALI.</p>

  • Laparoscopy-assisted distal gastrectomy in a case of gastric cancer with situs inversus totalis

     View Summary

    <p>Situs inversus totalis (SIT) is a rare congenital condition in which abdominal and thoracic organs are transposed from normal positions. Laparoscopy-assisted distal gastrectomy for situs inversus totalis is technically difficult and has rarely been reported. Here, we report the case of man in his 40s with situs inversus totalis and a preoperative diagnosis of stage IA gastric cancer (cT1b, cN0, cM0). We successfully performed laparoscopy-assisted distal gastrectomy with D1+ lymph node dissection and Billroth I reconstruction. To ensure a safe procedure, we evaluated the vessels preoperatively with 3-D CT angiography. Furthermore, we performed the surgery by reversing our surgical positions, using a two-monitor method, and then reconstructing under direct vision through the incision. The surgery was performed with minimal blood loss, and no severe postoperative complications were observed. Histopathological examination revealed poorly to moderately differentiated stage IA (pT1b, pN0, pM0) adenocarcinoma. No recurrence has been observed as of 2 years postoperatively.</p>
