"ABSTRACTPurpose: Whether or not gastrectomy is feasible for very elderly gastric cancer patients is unclear. This study aimed to clarify the feasibility and safety of surgical treatment for patients in this age group.Method: The study included 55 very elderly patients with resectable gastric cancer who underwent gastrectomy (≥ 85 years of age; very-E group). The surgical outcomes were compared with those of 611 elderly patients (75-84 years old; E group).Results: Female sex, a poor physical and performance status, and a low serum albumin level patients were more frequent in the very-E group than in the E group. Lymphadenectomy was less aggressive in the very-E group than in the E group (P < 0.001). The overall postoperative complication rate was not significantly different between the groups (46 vs 33%; P = 0.073). A multivariate analysis to predict the overall survival identified male sex (hazard ratio 1.75, 95% confidence interval 1.30-2.36), low body mass index (2.19, 1.52-3.16), poor performance status (2.14, 1.60-2.86), low serum albumin level (1.84, 1.37-2.48), and advanced tumor stage (1.71, 1.29-2.27) but not age (1.31, 0.84-2.03) as independent prognostic factors.Conclusion: Chronological age alone is not a contraindicative factor for gastrectomy in very elderly patients."

"PURPOSE: To assess the safety and feasibility of laparoscopic gastrectomy (LG) for gastric cancer patients with a history of abdominal surgery (HAS).METHODS: This retrospective study analyzed data collected from gastric cancer patients with HAS, who underwent LG between 2004 and 2015. We compared the clinicopathological features that correlated with conversion to open surgery and the development of severe postoperative complications (Clavien-Dindo classification of grade III or higher).RESULTS: Of the 41 patients identified, 6 (14.6%) required conversion to open surgery. The incidence of conversion to open surgery was associated with a history of lower gastrointestinal tract surgery (p = 0.009), attempted laparoscopic total gastrectomy (p = 0.002), and excessive blood loss (p < 0.001). Severe postoperative complications developed in six patients (14.6%). Although the development of complications was associated with high postoperative serum C-reactive protein, the type of past abdominal surgery was not significantly correlated with severe complications.CONCLUSIONS: LG was feasible for gastric cancer patients with a HAS, but for those with a history of lower abdominal surgery or those who require total gastrectomy, surgeons should carefully consider the indications for LG."

"ABSTRACTPurposesLaparoscopic gastrectomy using ultrasonic devices occasionally causes postoperative pancreatic fistula. Robotic gastrectomy using monopolar scissors may reduce intraoperative injury to the pancreas. We evaluated the safety and feasibility of robotic gastrectomy.MethodsA multicenter prospective study was conducted to evaluate the surgical outcomes of robotic gastrectomy. The primary endpoints were the incidence of intraoperative and postoperative complications and operative mortality.ResultsA total of 115 patients were enrolled. The clinical T stages were T1 in 68 patients and T2 or higher in 47 patients. The types of surgery included distal gastrectomy (n = 72), total gastrectomy (n = 39), and proximal gastrectomy (n = 4). Two patients developed intraoperative complications (1,7%), but no cases required conversion to open surgery. The amylase concentration in drainage fluid was higher in cases with pancreatic compression, especially in those with compression for longer than 20 min. Postoperative complications of Clavien-Dindo grade ≥ II occurred in 11 patients (9,6%). There was no mortality. A multivariate analysis indicated that a high body mass index and pancreatic compression by an assistant for longer than 20 min were independent risk factors for postoperative complications (P = 0,029 and P = 0,010). Conclusions Robotic gastrectomy using monopolar scissors is safe and feasible. Robotic dissection without compression of the pancreas may reduce postoperative complications."

"Purpose: This multicenter, randomized controlled study evaluates the safety of early oral feeding following gastrectomy, and its effect on the length of postoperative hospital stay.Methods: The subjects of this study were patients who underwent distal gastrectomy (DG) or total gastrectomy (TG) for gastric cancer between January 2014 and December 2015. Patients were randomly assigned to the early oral feeding group (intervention group) or the conventional postoperative management group (control group) for each procedure. We evaluated the length of postoperative hospital stay and the incidence of postoperative complications in each group.Results: No significant differences in length of postoperative stay were found between the intervention and control groups of the patients who underwent DG. The incidence of postoperative complications was significantly greater in the DG intervention group. In contrast, the length of postoperative stay was significantly shorter in the TG intervention group, although the TG group did not attain the established target sample size.Conclusion: Early oral feeding did not shorten the postoperative hospital stay after DG. The higher incidence of postoperative complications precluded the unselected adoption of early oral feeding for DG patients. Further confirmative studies are required to definitively establish the potential benefits of early oral feeding for TG patients."

"ABSTRACTPurposeTo classify the shape of the remnant stomach after Billroth-I (B-I) reconstruction and evaluate the relationship between the shape of the remnant stomach and the postoperative clinical outcomes.MethodsOne hundred and ninety-five consecutive patients with gastric cancer underwent distal gastrectomy with B-I reconstruction between May 2006 and October 2014. We retrospectively reviewed their medical records and radiological findings. Finally, the shapes of the remnant stomach of 150 patients were classified as either straight type (type A) or stagnant type (type B). The clinical outcomes were compared with respect to the types of remnant stomach.ResultsThe incidence of anastomotic leakage was significantly higher in the type A group than in the type B group (9.4 vs. 1.5%, p = 0.044). The body weight change ratio after surgery was significantly lower in the type B group than in the type A group [p = 0.0068, two-way repeated measures analysis of variance (ANOVA)], while the serum albumin levels showed marginally significant improvement in the type B group compared with the type A group (p = 0.0542, two-way repeated measures ANOVA).ConclusionThe shape of the remnant stomach after distal gastrectomy with B-I reconstruction might influence the degree of anastomotic leakage and long-term nutritional status."

"PURPOSE: A triplet regimen of docetaxel, cisplatin, and S-1(DCS) is highly effective against metastatic gastric cancer. We performed this study to clarify the safety and efficacy of surgical resection in patients with initially unresectable gastric cancer, after down-staging or disease control was achieved by DCS chemotherapy.METHODS: The subjects of this retrospective study were 31 consecutive patients with initially unresectable gastric cancer, who underwent surgical resection between October, 2006 and December, 2012, after downstaging or disease control was achieved by DCS chemotherapy. We evaluated the clinicopathological factors and clinical outcomes and assessed radiographic response based on the RECIST criteria, not by central review.RESULT: Before DCS chemotherapy, 18 patients had extraregional lymph node metastasis, 5 had liver metastasis, 8 had macroscopic peritoneal metastasis, and 8 had pancreatic head invasion. Twenty-three (74.2%) of the 31 patients underwent R0 resection. Postoperative morbidity and mortality rates were 16.1 and 0%. During chemotherapy, grade 3/4 toxicities included neutropenia (54.8%), leukopenia (32.3%), and anemia (16.1%). Median progression-free survival and median overall survival (OS) were 42.1 and 56.1 months, respectively. These results were similar for all patients, except those with locally advanced disease alone. In the multivariate analysis for OS, ypN remained an independent negative prognostic factor (p = 0.018).CONCLUSION: Surgical resection after DCS chemotherapy for initially unresectable gastric cancer was safe and provided a reasonable R0 resection rate and good midterm survival."

"The first laparoscopy-assisted gastrectomy for gastric cancer was performed in Japan in 1991. In the ensuing 20 years, at first through a process of trial and error, then through the sharing of master surgeons’ accumulated experience, the procedure has been honed and refined to its current high level. From the beginning, it soon became evident that this much less invasive form of gastrectomy, in comparison with traditional open surgery, led to improved quality of life for postsurgical patients, and use of the procedure spread rapidly among gastric surgeons. Early on, however, there were calls for the establishment of standard techniques and procedures to be followed, with a recognized need to improve the level of safety and the quality of lymph node dissection for local control in cancer treatment. Toward that end, the Laparoscopy-Assisted Gastrectomy Club was formed in 1999. In the following year, because both Japan and Korea experience a high rate of gastric cancer, specialists from those two nations came together to form the Japan–Korea Laparoscopic gastrectomy joint seminar, to facilitate and encourage the exchange of vital information. The result has been to achieve an evolving consensus among specialists in the field of endoscopic surgery in Japan and Korea with expertise that can be shared worldwide. A compilation of the current state-of-the-art is now presented in this volume, with accompanying DVD, which will be of great value to all endoscopic surgeons who perform laparoscopic gastrectomy."

"Pasien dengan tumor lambung post operasi gastrektomi total memiliki risiko malnutrisi karena akan ada perubahan asupan nutrisi pada pasien. Dalam rangka mencegah terjadinya malnutrisi, pasien perlu mendapat edukasi nutrisi yang intensif agar efikasi diri, kepuasaan diri, dan asupan nutrisi pasien tidak mengalami penurunan. Penulisan karya ilmiah ini bertujuan untuk mengidentifikasi pengaruh edukasi nutrisi secara intensif terhadap status nutrisi dan kemunculan dumping syndrome pada pasien post operasi gastrektomi. Hasil evaluasi menggunakan instrumen Malnutrition Screening Tools (MST) menunjukan bahwa pasien tidak berisiko malnutrisi (skor= 2), IMT dalam kategori normal (25 kg/m²), hasil lab menunjukan Hb= 12,8 g/dL, Ht= 36%, dan GDS= 138 mg/dL, dan gejala dumping syndrome tidak muncul. Intervensi edukasi nutrisi secara intensif ini dapat diaplikasikan oleh tenaga kesehatan seperti perawat, dokter, dan ahli gizi sebagai upaya untuk mencegah terjadinya malnutrisi pada pasien post operasi gastrektomi.

Patients with gastric tumor after total gastrectomy have a risk of malnutrition because there will be changes in nutritional intake. In order to overcome malnutrition, patients need to receive intensive nutrition education so that self-efficacy, self-satisfaction and nutritional intake of patients do not decrease. This paper aims to identify the effect of nutrition education on nutritional status in patients postoperative total gastrectomy. The evaluation results using the Malnutrition Screening Instrument (MST) showed that patients were not at risk of malnutrition (score = 2), BMI in the normal category (25 kg / m2), result of biochemical showed Hb = 12.8 g / dL, Ht = 36%, and GDS = 138 mg / dL, and the dumping symptom syndrome did not occur. This intensive nutrition education intervention can be applied by health workers such as nurses as an effort to prevent the use of malnutrition in patients after total gastrectomy. "

"PurposeThe association between the preoperative absolute neutrophil count (NC), lymphocyte count (LC), and monocyte count (MC) in the peripheral blood and the prognosis of gastric cancer (GC) patients has not been investigated widely.MethodsWe enrolled 445 patients who underwent surgery for GC between January, 2005 and April, 2013 to analyze the correlations among NC, LC, and MC and their prognoses.ResultsBased on cut-off values calculated by ROC analysis, patients were sub grouped as having: NC ≥ 4477 (NCHigh), NC < 4477 (NCLow); and as LC ≥ 1447 (LCHigh), LC < 1447 (LCLow); and as MC ≥ 658,5 (MCHigh), MC < 658,5 (MCLow). Each group was assigned as follows; NCHigh group = 1, NCLow group = 0, LCHigh group = 0, LCLow group = 1, MCHigh group = 1, MCLow group = 0, and the sum of each score was defined as the lymphocyte-monocyte-neutrophil score (LMN score). The overall 5-year survival rates were 89%, 74%, 57,8%, and 53,3% for LMN scores of 0, 1, 2, and 3, respectively (P = 0,0004). Multivariate analysis indicated that the LMN score was an independent prognostic indicator.ConclusionsThe combination of preoperative NC, LC, and MC appears to be a useful indicator of GC prognosis."
