RESUMEN
A 77-year-old man with appetite loss was referred to our hospital. Upper gastrointestinal endoscopy and computed tomography(CT)revealed advanced gastric cancer in the antrum with duodenal and pancreatic invasion. After 6 courses of neoadjuvant docetaxel, cisplatin, and S-1(DCS)therapy, CT revealed marked tumor shrinkage. Distal gastrectomy was performed. Histopathological examination showed no residual tumor cells or lymph node metastasis, and thus, finally, pathological complete response was considered to have been achieved. The patient was doing well and disease-free 3 years later. Thus, neoadjuvant DCS therapy can be a promising treatment option for borderline resectable advanced gastric cancer.

BACKGROUND/AIM: Osteopontin (OPN) is a secretory glycoprotein, which is expressed not only in osteoblasts, but immune cells including macrophages and activated T cells. Its pleiotropic immune functions, such as bone remodeling, cancer progression, immune response, and inflammation have been reported previously. However, the association between OPN and postoperative complications (POC) after colorectal cancer (CRC) surgery has not been studied, so far. METHODS: Peripheral blood samples were collected before (pre) and immediately after surgery (post), and on postoperative days (POD) 1, 3, 5, and 7. Serum OPN levels were measured by ELISA. In total, 78 patients who underwent elective CRC surgery were divided into the No-POC (n = 54) and POC (n = 24) groups. RESULTS: The POC group had significantly higher OPN levels than the No-POC group throughout the postoperative observation period. The maximum OPN levels from pre- to postsurgical samples showed the best predictive potential for POCs (cut off: 20.75 ng/mL, area under the curve: 0.724) and were correlated with length of postoperative stays. OPN values were significantly correlated with C-reactive protein on POD3 and were identified as an independent predictive marker for POCs (odds ratio: 3.88, 95% CI: 1.175-12.798, P = 0.026). The severity of POCs was reflected in increased OPN levels. CONCLUSION: Increased postoperative OPN was associated with increased postoperative inflammatory host responses and POC after CRC surgery. Serum OPN level may be a useful biomarker for early prediction of POC and it may provide additional information for treatment decisions to prevent POC.

Genetic analysis and culturing techniques for gastric non-Helicobacter pylori Helicobacter (NHPH) are progressing. NHPH is reported to accompany nodular gastritis, gastric MALT lymphoma, and mild gastritis. However, only a few gastric cancer cases infected by NHPH have been reported. PCR analysis specific for NHPH and H. pylori was performed for DNA from gastric mucosa of 282 Korean gastric cancer patients, who were treated with endoscopic submucosal dissection. For more precise strain detection of NHPH, NHPH-positive mucosa was stained by immunohistochemistry specific for Helicobacter suis. The Cancer Genome Atlas (TCGA) classification was analyzed for these 3 gastric cancer sub-groups by in situ hybridization and immunohistochemistry. Among 281 patients, 3 patients (1.1%) were positive for NHPH. One patient (Patient 1) was also positive for H. pylori by PCR, another patient (Patient 3) was positive for serum IgG for H. pylori, and the other patient (Patient 2) had no evidence for H. pylori infection. Gastric mucosa of Patients 2 and 3 were positive for H. suis staining. All three NHPH-positive gastric cancers were located in the antrum, and belonged to the Chromosomal Instability Type of TCGA classification. Gastric NHPH can be a cause of gastric cancer, although likely with lower pathogenesis than H. pylori.

BACKGROUND/AIM: The impact of clinical response to taxanes plus ramucirumab (RAM) on overall survival (OS) has not been clarified for advanced gastric cancer (AGC), although this type of therapy is already in use as second-line chemotherapy (CTx). This study aimed to investigate the prognostic impact of the clinical response to taxanes plus ramucirumab (RAM) for AGC patients. PATIENTS AND METHODS: This study included AGC patients treated with paclitaxel (PTX) or nab-paclitaxel (nab-PTX) and RAM. A retrospective analysis of response and survival rates in consecutive medical records of patients was performed. RESULTS: Forty-two patients were enrolled. Median progression-free survival and OS were 5.4 months [95% confidence interval (CI)=4.440-6.361] and 11.8 months (95% CI=8.648-15.019), respectively. In Cox-hazard multivariate analysis, peritoneal metastasis [hazard ratio (HR)=2.830; 95% CI=1.320-6.067; p=0.008], and disease control rate (HR=0.310; 95% CI=0.129-0.741; p=0.008) were independent factors. CONCLUSION: The response to taxanes plus RAM CTx had an impact on the survival of patients with AGC.

BACKGROUND: The incidence of internal hernias has recently increased in concordance with the popularization of laparoscopic surgery. Of particular concern are internal hernias occurring in Petersen's space, a space that is surgically created after treatment for gastric cancer and obesity. These hernias cause devastating sequelae, such as massive intestinal necrosis, fatal Roux limb necrosis, and superior mesenteric vein thrombus. In addition, protein-losing enteropathy (PLE) is a rare syndrome involving gastrointestinal protein loss, although its relationship with internal Petersen's hernias remains unknown. CASE SUMMARY: A 75-year-old man with a history of laparotomy for early gastric cancer developed Petersen's hernia 1 year and 5 mo after surgery. He was successfully treated by reducing the incarcerated small intestine and closure of Petersen's defect without resection of the small intestine. Approximately 3 mo after his surgery for Petersen's hernia, he developed bilateral leg edema and hypoalbuminemia. He was diagnosed with PLE with an alpha-1 antitrypsin clearance of 733 mL/24 h. Double-balloon enteroscopy revealed extensive jejunal ulceration as the etiology, and it facilitated minimum bowel resection. Pathological analysis showed extensive jejunal ulceration and collagen hyperplasia with nonspecific inflammation of all layers without lymphangiectasia, lymphoma, or vascular abnormalities. His postoperative course was unremarkable, and his bilateral leg edema and hypoalbuminemia improved after 1 mo. There was no relapse over the 5-year follow-up period. CONCLUSION: PLE and extensive jejunal ulceration may occur after Petersen's hernia. Double-balloon enteroscopy helps identify and resect these lesions.
RESUMEN
Although the incidence of gastric cancer has decreased because of the lower rate of Helicobacter pylori infection, it still accounts for a large number of deaths in Japan. Gastric cancer is mainly treated by resection, and the rate of radical resection is high in Japan because approximately 50% of cases are diagnosed at an early stage. Treatment advances have increased the number of endoscopic submucosal dissections, and development of laparoscopic surgery and robot-assisted surgery as minimally invasive approaches has yielded results similar to those of conventional surgeries, at least in the short term. Cases for which resection is contraindicated are treated with chemotherapy if performance status can be maintained. Although anticancer drugs are continuously under development, treatment outcomes remain unsatisfactory. As Japan becomes a super-aging society, the number of refractory cases is projected to increase. Therefore, evidence of any benefit for minimally invasive surgery and function-preserving surgery needs to be reported quickly. In this paper, we discuss gastric cancer treatment modalities recommended in the fifth edition of the gastric cancer treatment guidelines and describe recent research findings.

INTRODUCTION: Laparoscopic surgery is a minimally invasive surgery; however, obstacles to its functional optimization remain. Surgical ports can accommodate only one instrument at a time so complex exchange manipulations are necessary during surgery which increases operation times and patient risk. We developed a new laparoscopic instrument that functions as both forceps and a suction tube, which renders intraoperative tool exchange unnecessary. This pilot study was undertaken to evaluate the safety and efficacy of this novel dual-function device in laparoscopic surgery for gastric cancer. METHODS: This single-center pilot study assessed patient safety during and after laparoscopic distal gastrectomy for gastric cancer with the suction-forceps using intraoperative video and clinical follow-up, respectively. To evaluate instrument efficacy, we measured the time interval between the start of any bleeding and the start of aspiration ("suction access time") and compared this time with that of a conventional surgical setup. RESULTS: In total 15 patients participated, with all procedures being successful. No excess tissue damage occurred during surgery. Suction access time was significantly shorter in cases of bleeding when the suction-tip forceps were used for aspiration (2.01 seconds) compared to an ordinary suction tube (12.5 seconds; P < .01). CONCLUSION: These findings suggest that our new suction-tip forceps are a useful, safe, and efficacious operative tool. This surgical innovation may considerably simplify gastric laparoscopic surgery. This pilot study was registered with Japan Clinical Trial Registration on 22 June 2017 (registration number: UMIN000027879).

Various types of obstruction can occur after a gastrectomy for gastric cancer. If proper treatment is not performed, such obstructions can lead to serious conditions. Early postoperative Roux limb torsion is a rare complication, and few reports of endoscopic treatment for this complication have been made. In the present report, we describe the endoscopic detorsion of Roux limb torsion in two patients. The first case was a 77-year-old woman who underwent a laparoscopic distal gastrectomy with Roux-en-Y (R-Y) reconstruction for early gastric cancer and a laparoscopic ileocecal resection (ICR) for early colorectal cancer. On the 12th day after the gastrectomy, a Roux limb torsion was observed. Endoscopic detorsion was performed, and the patient recovered. She was discharged on postoperative day 40. The second case was a 73-year-old man who underwent a laparoscopic-assisted total gastrectomy with a R-Y reconstruction for early gastric cancer. On the 8th day after the gastrectomy, a Roux limb torsion occurred at the Y-shaped anastomosis (Y-anastomosis). Endoscopic detorsion was performed, and the patient recovered. He was discharged on postoperative day 17. In summary, we experienced two cases in which an endoscopic reduction of a Roux limb torsion was performed at the Y-anastomosis after gastrectomy with R-Y reconstruction. This study presents a further review of these cases and a summary of the existing literature.

AIM: Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to control postoperative pain; however, their postoperative use has been associated with anastomotic leakage after gastrointestinal surgery. This systematic review and meta-analysis aimed to determine the correlation between the use of NSAIDs and anastomotic leakage. METHODS: We conducted a comprehensive electronic literature search up to August 2018 to identify studies comparing anastomotic leakage in patients with and without postoperative NSAID use following gastrointestinal surgery. We then carried out a meta-analysis using random-effects models to calculate odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Twenty-four studies were included in this meta-analysis, including a total of 31 877 patients. Meta-analysis showed a significant association between NSAID use and anastomotic leakage (OR 1.73; 95% CI = 1.31-2.29, P < .0001). Subgroup analyses showed that non-selective NSAIDs, but not selective cyclooxygenase-2 inhibitors, were significantly associated with anastomotic leakage. However there was no significant subgroup difference between selective and non-selective NSAIDs. CONCLUSION: Results of this meta-analysis indicate that postoperative NSAID use is associated with anastomotic leakage following gastrointestinal surgeries. Caution is warranted when using NSAIDs for postoperative analgesic control in patients with gastrointestinal anastomoses.
RESUMEN
BACKGROUND AND AIM: Postoperative infectious complications (POI), which can increase length of hospital stay, medical cost, and worsen overall survival, are a concern in minimally invasive colorectal cancer (CRC) surgeries. Recent reports showed that relatively new inflammation-based score, lymphocyte-to-monocyte ratio (LMR) is an independent predictor of long-term outcomes after CRC surgeries. In this study, LMR was evaluated as a predictor of short-term postoperative outcomes. PATIENTS AND METHODS: This was a single-institutional retrospective study of 211 consecutive patients who had undergone laparoscopic CRC surgery with primary tumor resection from January 2014 to August 2015 at Nippon Medical School Chiba Hokusoh Hospital. The patients were divided into two groups (no POI; n = 176 and POI; n = 35). The associations between inflammation-based scores, namely neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and LMR, and the occurrence of POI were investigated. Receiving operator characteristic curve analysis was used to determine the cutoff point of preoperative LMR. RESULTS: Low LMR (cut-off 3.46), long operative time, and smoking were found to be independent predictors of POI in a multivariate analysis (LMR: Odds ratio 5.61, 95% confidence interval 1.98-15.9, P = 0.001). Patients with low LMR also appeared to have more advanced and aggressive tumours. CONCLUSION: This is the first study to report that the lower LMR is a predictive factor of POI after laparoscopic CRC surgery, and it may provide additional information for treatment decisions to prevent POI.

After undergoing an upper gastrointestinal endoscopy, a 74-year-old woman with anemia was diagnosed with advanced lower gastric cancer. We performed laparotomy and identified the tumor as unresectable because of the direct invasion to the pancreas. S-1 was administered at 60mg/day for 2 weeks followed by 1-week discontinuation. After 6 weeks, we changed the schedule to the same dosage of S-1 for 1 week followed by 2-week discontinuation. CT and endoscopic findings showed complete response after 64weeks of S-1 administration. Since then, S-1 has been maintained at 60mg/day intermittently for 14 days in 7 weeks accordingto the patient's condition. The patient is currently doingwell with a complete response for more than 5 years.

BACKGROUND/AIM: TAS-102 is recommended as salvage-line therapy for metastatic colorectal cancer (mCRC), but practical predictors for its efficacy are lacking. PATIENTS AND METHODS: In a single-institutional retrospective study of 33 patients treated with TAS-102, we investigated the predictive value of the pretreatment neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR), and lymphocyte-monocyte (LMR) ratios for progression-free (PFS) and overall (OS) survival. Predictive ability using cut-offs of the median value (3.14) and 5 for NLR were compared. RESULTS: In univariate analysis, Eastern Cooperative Oncology Group performance score, NLR, and PLR were negatively significantly associated with PFS and OS. The number of treatment lines was negatively associated with PFS. The NLR cut-off of 5 was superior to the median value. Multivariate analyses showed a significant prognostic impact for NLR at cut-off 5 (hazard ratio(HR)=6.26, p=0.02 for PFS; HR=6.97, p=0.07 for OS). CONCLUSION: The pretreatment NLR is a prognostic biomarker for patients with mCRC who receive TAS-102 treatment.

BACKGROUND: Recent studies suggested that galectin-3 may act as a pro-inflammatory damage-associated molecular pattern. The aim of this study is to investigate the association between blood galectin-3 and postoperative complications (POC) after colorectal cancer (CRC) surgery. METHODS: Blood samples were taken from 35 patients with CRC before surgery, immediately after surgery, and on postoperative days (POD) 1, 3, 5, and 7. Blood galectin-3 and interleukin-6 levels were measured by commercially available ELISA. Patients were divided into those with (POC group) and without POC (no-POC group). RESULTS: Significantly higher galectin-3 levels were observed pre- and postoperatively in the POC group (n=10) compared with those of the no-POC group (n=25). Galectin-3 levels on POD1 showed the best predictive potential for POC (cut-off: 3.18 pg/mL, area under the curve: 0.868). CONCLUSIONS: These results indicate that increased perioperative blood galectin-3 levels may be associated with POC after CRC surgery.

PURPOSE: Preoperative intestinal decompression, using either a self-expandable metallic stent (SEMS) as a bridge to surgery (BTS) or a transanal decompression tube (TDT), provides an alternative to emergency surgery for malignant large-bowel obstruction (MLBO). We conducted this meta-analysis to compare the short-term outcomes of SEMS placement as a BTS vs. TDT placement for MLBO. METHODS: We conducted a comprehensive electronic search of literature published up to March, 2018, to identify studies comparing the short-term outcomes of BTS vs. TDT. Decompression device-related and surgery-related variables were evaluated and a meta-analysis was performed using random-effects models to calculate odd ratios with 95% confidence intervals. RESULTS: We analyzed 14 nonrandomized studies with a collective total of 581 patients: 307 (52.8%) who underwent SEMS placement as a BTS and 274 (47.2%) who underwent TDT placement. The meta-analyses showed that the BTS strategy conferred significantly better technical and clinical success, helped to maintain quality of life by allowing free food intake and temporal discharge, promoted laparoscopic one-stage surgery without stoma creation, and had equivalent morbidity and mortality to TDT placement. CONCLUSIONS: Although the long-term outcomes are as yet undetermined, the BTS strategy using SEMS placement could be a new standard of care for preoperative decompression to manage MLBO.

BACKGROUND: The short-term safety and efficacy of insertion of a self-expandable metallic colonic stent (SEMS) followed by elective surgery, "bridge to surgery (BTS)", for malignant large bowel obstruction (MLBO) have been well described; however, the influence on long-term oncological outcomes is unclear. The aim of this study was to evaluate changes in oncological characteristics in colorectal cancer (CRC) tissues after SEMS insertion, focusing on growth factors, cell cycle and apoptosis. METHODS: From January 2013 to September 2014, a total of 25 patients with MLBO who underwent BTS at our single institution were retrospectively included. Paired CRC tissue samples before (endoscopic biopsy) and after SEMS insertion (surgically resected) were collected from each patient. EGFR, VEGF, Ki-67, p27kip1 and TUNEL expression were determined by immunohistochemistry. RESULTS: No clinical or subclinical perforations evaluated by mechanical ulceration pathologically were observed. Epithelial exfoliation, tumour necrosis, infiltration of inflammatory cells and fibrosis were observed in SEMS-inserted surgically-resected specimens. Overall, 84% (21/25) and 60% (15/25) of patients exhibited no change or a decrease in staining category, respectively, for EGFR and VEGF expression after SEMS insertion. A significant decrease in Ki-67 expression was observed in surgically-resected specimens compared with endoscopic biopsy specimens (P < 0.01). The upstream cell cycle inhibitor, p27kip1, was significantly increased after SEMS insertion (P = 0.049). CONCLUSIONS: Although the long-term safety of BTS should be determined in a future clinical trial, mechanical compression by SEMS may suppress cancer cell proliferation and this result could provide some insights into the issue.

BACKGROUND: Self-expandable metallic stent placement is a widely performed palliative procedure or bridge to surgery for obstructive colorectal cancer. However, the feasibility of this procedure for large bowel obstruction induced by effective neoadjuvant therapy is unclear. CASE PRESENTATION: We herein report three such cases involving a 61-year-old man who underwent neoadjuvant chemoradiotherapy for lower rectal cancer, a 56-year-old woman who underwent neoadjuvant chemotherapy for lower rectal cancer, and a 63-year-old woman who underwent neoadjuvant chemotherapy for lower rectal cancer. All were emergently hospitalized with large bowel obstruction that developed while undergoing neoadjuvant therapy. Colonoscopy revealed smooth strictures caused by effective neoadjuvant therapy. Self-expandable metallic stents were placed across the obstruction as a bridge to surgery, and laparoscopic low anterior resection was uneventfully performed in all patients. CONCLUSIONS: We successfully treated three patients with large bowel obstruction induced by a good response to neoadjuvant therapy using self-expandable metallic stents as a bridge to surgery. Further studies with larger sample sizes are warranted to assess the feasibility of this strategy.
RESUMEN
OBJECTIVES: The aim of this study was to investigate the risk factors for postoperative complications (POCs) and optimal interval between a self-expandable metallic stent (SEMS) placement and elective surgery, "bridge to surgery (BTS)" in patients with malignant large bowel obstruction. MATERIALS AND METHODS: BTS strategy was attempted in 49 patients with malignant large bowel obstruction from January 2013 to March 2017 in our institution. Two of these patients were excluded because they had undergone emergency surgery for SEMS migration. RESULTS: Of these 47 patients, 8 had developed POC (Clavien-Dindo grading ≥II), whereas 39 patients had no such complications. Multivariate analysis identified only the interval between SEMS and surgery as an independent risk factor for POC. Furthermore, a cutoff value of 15 days for interval between SEMS and surgery was identified by receiver operating characteristic curve analysis. CONCLUSIONS: An interval of over 15 days is recommended for minimizing POC in patients undergoing elective surgery in a BTS setting.

PURPOSE: Lysophosphatidylcholine (LPC), which is generated from phosphatidylcholine (PC) and metabolized by autotaxin (ATX), modulates immune responses via its anti-inflammatory property. We investigated the association between LPC and postoperative complications (POCs) after colorectal cancer surgery (CRC). METHODS: The subjects of this study were 43 patients who underwent surgery for CRC. Peripheral blood samples were collected preoperatively and immediately after surgery, and on postoperative days (PODs) 1, 3, 5, and 7. Patients were divided into a No-POC group (n = 33) and a POC group (n = 10). Blood LPC, IL-6, PC, and ATX levels were measured by specific enzymatic assays or ELISA. RESULTS: The postoperative to preoperative LPC ratios were lowest on POD 1 in both groups. The POC group had significantly lower LPC ratios throughout the perioperative period than the No-POC group. The LPC ratios were inversely correlated with IL-6. The predictive impact of LPC ratios on POCs was demonstrated by ROC analysis (cut-off 51.2%, AUC 0.798) and multivariate analysis (OR 15.1, P = 0.01). The postoperative PC ratios decreased more after surgery in the POC group. ATX levels did not change significantly in either group. CONCLUSIONS: Decreased postoperative LPC is associated with increased postoperative inflammatory response and POCs. The decreased PC supply to the circulation is a mechanism of the postoperative LPC decrease.

Along with the increased use of other laparoscopic procedures, laparoscopic inguinal hernia repair has become widely used because of its minimally invasive nature. Here, we report a case of 66-year-old man who underwent transabdominal preperitoneal laparoscopic hernioplasty and developed hemorrhagic shock on postoperative day 1. CT showed postoperative venous hemorrhage from the retropubic space. Successful hemostasis of the massive hemorrhage was achieved laparoscopically. The origin of the hemorrhage was assumed to be the corona mortis vein, which was slightly injured during the operation. Despite the rarity of this complication, surgeons must be aware of the need to carefully dissect and fix the mesh in the retropubic space to avoid injuring the corona mortis. Laparoscopic hemostasis may be an effective alternative to the open approach.

INTRODUCTION: Laparoscopic transabdominal preperitoneal repair (TAPP) is widely accepted in elective inguinal hernioplasty. However, given the scarcity of data, the feasibility and safety of TAPP in strangulated hernia cases have not yet been determined. METHODS: We retrospectively evaluated the data from a consecutive series of 33 patients who had undergone surgery for acute strangulated inguinal hernia associated with suspected visceral ischemic damage by either TAPP (TAPP group, n = 11) or conventional open hernioplasty via the anterior approach (anterior group, n = 22). RESULTS: The TAPP group had a significant longer surgical duration than the anterior group (147 vs 84 min) and relatively less blood loss. Incision and enlargement of the hernial orifice, which enables easy reduction of the strangulated organ, was performed in the last 7 of 11 cases in the TAPP group. The morbidity was lower in the TAPP group, but the difference was not statistically significant (18% vs 23%). The TAPP group had a significantly shorter postoperative hospital stay than the anterior group (7 vs 10 days). CONCLUSION: For surgeons with sufficient knowledge of the anatomy and expertise in reducing the strangulated organ, TAPP for strangulated inguinal hernia is at least comparable to open hernioplasty via the anterior approach in short-term outcomes.
