Machine Learning Predicts the Need for Surgical Intervention in Adhesive Small Bowel Obstruction.

Objectives: To explore the predictive performance on the need for surgical intervention in patients with adhesive small bowel obstruction (ASBO) using machine-learning (ML) algorithms and investigate the optimal timing for transition to surgery.

Methods: One hundred and six patients with ASBO who initially underwent long transnasal intestinal tube (LT) decompression were enrolled in this retrospective study. Traditional logistic regression analysis and ML algorithms were used to evaluate the risk of need for surgical intervention.

[Recurrent Esophageal Cancer Showing Good Response to Nivolumab in a Super-Elderly Patient-A Case Report].

A 91-year-old man with thoracic esophageal cancer(pT3N1M0, pStage Ⅲ)and gastric cancer(pT1b2N0M0, pStage ⅠA)underwent esophagectomy. Three years and 4 months postoperatively, chest computed tomography revealed a mass shadow near the aortic arch. Upper gastrointestinal endoscopy revealed a submucosal tumor-like lesion on the left wall of the gastric tube, which was identified as recurrent esophageal cancer.

[A Case of Pathological Complete Response Achieved with Neoadjuvant DCS Therapy in Gastric Cancer].

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.

The utility of serum osteopontin levels for predicting postoperative complications after colorectal cancer surgery.

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.

Non-Helicobacter pylori Helicobacter (NHPH) positive gastric cancer.

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.

Protein-losing enteropathy caused by a jejunal ulcer after an internal hernia in Petersen's space: A case report.

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.

Treatment of Gastric Cancer in Japan.

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.

Endoscopic Detorsion for Early Postoperative Roux Limb Torsion after Laparoscopic Gastrectomy: A Case Report and Literature Review.

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.

Evaluation of the safety and efficacy of suction-tip forceps, a new tool for laparoscopic surgery, for gastric cancer.

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.

Preoperative lymphocyte-to-monocyte ratio predicts postoperative infectious complications after laparoscopic colorectal cancer surgery.

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.

[Long-Term Complete Response in an Unresectable Advanced Gastric Cancer Patient Treated with Low-Dose S-1].

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.

Pretreatment Neutrophil-to-Lymphocyte Ratio Predicts Survival After TAS-102 Treatment of Patients With Metastatic Colorectal Cancer.

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.

Blood Galectin-3 Levels Predict Postoperative Complications after Colorectal Cancer Surgery.

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.

Colonic stent-induced mechanical compression may suppress cancer cell proliferation in malignant large bowel obstruction.

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.

Placement of a self-expandable metallic stent as a bridge to surgery for large bowel obstruction induced by effective neoadjuvant therapy: report of three cases.

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.

Optimal Interval From Placement of a Self-expandable Metallic Stent to Surgery in Patients With Malignant Large Bowel Obstruction: A Preliminary Study.

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.

Lysophosphatidylcholine as a predictor of postoperative complications after colorectal cancer surgery.

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.

Laparoscopic transabdominal preperitoneal repair for strangulated inguinal hernia.

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).

Life-threatening hemorrhage from the corona mortis after laparoscopic inguinal hernia repair: Report of a case.

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.

Laparoscopic mesh repair for lumbar hernia after iliac crest bone harvest.

Lumbar hernia after iliac crest bone harvest is relatively rare. When it does occur, it presents as a flank abdominal protrusion through a lateroposterior abdominal wall defect. A laparoscopic approach for this type of hernia is reported to have advantages over the classic open method.
