Background/Aims: Patients with postoperative pulmonary complications after esophagectomy often have increased mortality. The purpose of the study was to examine the efficacy of preventing postoperative pulmonary complications by an intensive preoperative respiratory rehabilitation (PR) program for esophageal cancer patients. Methods: This study was a prospective randomized controlled study. Thirty patients in the PR group and 30 patients in the no preoperative respiratory rehabilitation (NPR) group were included. The PR group received preoperative rehabilitation for more than 7 days, while the NPR group did not receive any preoperative rehabilitation. All patients underwent postoperative rehabilitation from the first postoperative day. The postoperative pulmonary complications were evaluated using the Clavien-Dindo classification (CDC) and the Utrecht Pneumonia Scoring System (UPSS). Results: The CDC grade in the PR group was significantly lower than that in the NPR group (p = 0.014). The UPSS score in the PR group was significantly lower than that in the NPR group at postoperative day 1 (p = 0.031). In the multivariate analysis, NPR was an independent risk factor for postoperative pulmonary complications greater than CDC grade II (OR: 3.99, 95% CI: 1.28-12.4, p = 0.017). Conclusions: This study showed that the intensive PR program was capable of reducing the postoperative pulmonary complications in esophageal cancer patients.

Abstract. The aim of the present study was to estimate the effect of the perioperative administration of probiotics in patients undergoing colorectal cancer (CRC) surgery. The study focused on a total of 156 consecutive surgeries carried out from among all the elective CRC surgeries performed between

Aim: The aim of the present study was to evaluate the superiority of the high-sensitivity modified Glasgow prognostic score (HS-mGPS) before surgery in patients with gastric cancer. Patients and Methods: The participants of this retrospective study comprised 552 patients with gastric cancer who underwent gastrectomy at the Fukuoka University Hospital. The HS-mGPS was calculated before surgery based on cutoff values of 0.3 mg/dl for C-reactive protein and 3.5 g/dl for albumin, and correlations between the HS-mGPS and the clinicopathological parameters and prognosis were evaluated. In addition, the superiority of the HS-mGPS to the mGPS as a prognostic indicator was examined in detail. Results: The mGPS was 0 in 494 patients, 1 in 24 patients and 2 in 34 patients. In contrast, the HS-mGPS was 0 in 411 patients, 1 in 75 patients and 2 in 66 patients. Both the mGPS (p < 0.0001) and HS-mGPS (p < 0.0001) were good prognostic predictors in gastric cancer patients who underwent gastrectomy. Of the 494 patients with an mGPS of 0 before surgery, 51 and 32 exhibited an HS-mGPS of 1 and 2, respectively. The patients who exhibited migration in the HS-mGPS demonstrated a significantly more unfavorable prognosis than the patients with an HS-mGPS of 0 (p < 0.0001). The prognostic impact of the HS-mGPS was especially clear in stage I and IV patients (p = 0.0027, p = 0.017). The HS-mGPS was found to be a superior prognostic predictor compared to the mGPS in a multivariate analysis (p = 0.0002). Conclusions: The HS-mGPS before surgery is a superior prognostic predictor in patients with gastric cancer.

Gastric stump carcinoma was initially reported by Balfore in 1922, and many reports of this disease have since been published. We herein review previous reports of gastric stump carcinoma with respect to epidemiology, carcinogenesis, Helicobacter pylori (H. pylori) infection, Epstein-Barr virus infection, clinicopathologic characteristics and endoscopic treatment. In particular, it is noteworthy that no prognostic differences are observed between gastric stump carcinoma and primary upper third gastric cancer. In addition, endoscopic submucosal dissection has recently been used to treat gastric stump carcinoma in the early stage. In contrast, many issues concerning gastric stump carcinoma remain to be clarified, including molecular biological characteristics and the carcinogenesis of H. pylori infection. We herein review the previous pertinent literature and summarize the characteristics of gastric stump carcinoma reported to date.

Background: The Geriatric Nutritional Risk Index (GNRI) is a new index recently introduced for predicting the risk of nutrition-related complications. The GNRI has mainly been reported as a simple and accurate tool to assess the nutritional status and prognosis of elderly patients. So far, there have been no reports of the GNRI in patients with gastrointestinal cancer. Our objective was to examine the association between the GNRI and short-term outcomes, especially postoperative complications, in patients with esophageal cancer who underwent esophagectomy and gastric tube reconstruction. Materials and Methods: The present study enrolled 122 consecutive patients with esophageal cancer who underwent esophagectomy and gastric tube reconstruction. The GNRI at admission to the hospital was calculated as follows: (1.489 × albumin in g/l) + (41.7 × present/ideal body weight). The characteristics and short-term outcomes were compared between two groups: the high (GNRI ≥90) and the low (GNRI <90) GNRI group. The mortality and morbidity rates, especially the rates regarding respiratory complications and anastomotic leakage, were investigated. Results: The mean age of the 122 patients was 63.9 ± 9.1 years (range 43-83). There were no significant differences in either patient or operative characteristics. The low GNRI group had a significantly higher rate of respiratory complications (p = 0.002). A multivariate analysis demonstrated that the GNRI was the only independent significant factor predicting respiratory complications (hazard ratio 3.41, 95% confidence interval 1.19-9.76; p = 0.022). Conclusion: The GNRI is considered to be a clinically useful marker that can be used to assess the nutritional status and predict the development of postoperative respiratory complications in patients with esophageal cancer undergoing esophagectomy and gastric tube reconstruction.
