The World Health Organization recommends using wound protector devices in abdominal surgery as a preventive measure to lower the risk of SSIs despite limited evidence.

Objective: To examine the efficacy of a dual-ring, plastic wound protector in lowering the SSI rate in open gastrointestinal (GI) surgery irrespective of intra-abdominal contamination levels.

Outcomes of laparoscopic single-incision caecal pole resection for low-grade appendiceal mucinous neoplasm.

Introduction: Low-grade appendiceal mucinous neoplasm (LAMN) is a rare disease, and its clinical course varies from an incidental finding without symptoms to pseudomyxoma peritonei. Furthermore, there are few established treatment guidelines. This study was designed to confirm the outcomes in patients diagnosed with LAMN who underwent single-incision laparoscopic caecal pole resection.

A comparative study between transanal and transabdominal approaches in treatment of complete rectal prolapse.

Unlabelled: Formulating clear guidelines for the most reliable treatment methods for complete rectal prolapse appears challenging. The authors designed this study to compare the results according to the approaches for female complete rectal prolapse and to suggest a more effective method. The transanal and abdominal groups showed differences in operating time, hospital stay, and recurrence rate.

Recurrent bleeding after posthemorrhoidectomy caused by factor V deficiency: a case report and review of the literature.

Congenital factor V (FV) deficiency is a rare hemorrhagic disorder that can cause excessive bleeding during and after surgery in the affected patient. This report is the case of a patient who had FV deficiency with recurrent posthemorrhoidectomy bleeding treated with the hemostatic procedure and fresh frozen plasma (FFP) transfusions. A 45-year-old male patient had previously undergone hemorrhoidectomy for multiple hemorrhoids at a local hospital.

Purpose: This study aimed to evaluate the relationship between high-output stomas (HOSs), postoperative ileus (POI), and readmission after rectal cancer surgery with diverting ileostomy.

Methods: We included 302 patients with rectal cancer who underwent restorative resection with diverting ileostomy between January 2011 and December 2015. HOSs were defined as stomas with ≥ 2,000 mL/day output.

Tailored treatment of anastomotic leak after rectal cancer surgery according to the presence of a diverting stoma.

Purpose: A variety of clinical features of anastomotic leak occur during the surgical treatment of rectal cancer. However, little information regarding management of leakage is available and treatment guidelines have not been validated. The aim of this study was to evaluate the validity of currently proposed expert opinions on the management of anastomotic leak, after low anterior resection for rectal cancer.

Activation, Deficiency, and Reduced IFN-γ Production of Mucosal-Associated Invariant T Cells in Patients with Inflammatory Bowel Disease.

Mucosal-associated invariant T (MAIT) cells are innate-like T cells that can activate either in response to T-cell receptor (TCR) engagement or through activating cytokines and play an important role in autoimmune disorders. The study examined the level and function of MAIT cells in patients with inflammatory bowel disease (IBD). Circulating MAIT cell levels were significantly reduced in IBD patients.

Surgical approach for acute ischemic colitis after scuba diving: A case report.

The clinical manifestations that may occur due to decompression during scuba diving vary widely, but only mild symptoms have been reported mainly in the gastrointestinal tract. In particular, ischemic colitis caused by air embolism is rare. We report a case of full-thickness ischemic colitis treated with failed conservative treatment but successfully treated surgically.

Is radical surgery for clinical stage I right-sided colon cancer relevant? A retrospective review.

Purpose: Radical lymph node dissection for right-sided colon cancer is technically challenging. No clear guideline is available for surgical resection of clinical stage I right-sided colon cancer. This study was designed to review the pathologic stage of clinical stage I right-sided colon cancer and determine the relevant extent of surgical resection.

A prospective study of discrepancy between clinical and pathological diagnosis of appendiceal mucinous neoplasm.

Purpose: Appendiceal tumoral lesions can occur as benign, malignant, or borderline disease. Determination of the extent of surgery through accurate diagnosis is important in these tumoral lesions. In this study, we assessed the accuracy of preoperative CT and identified the factors affecting diagnosis.

Laparoscopic Resection of a Huge Retrorectal Tumor.

Retrorectal space tumors are rare, and so are frequently unrecognized, misdiagnosed, and mistreated. A 57-year-old man visited the outpatient clinic with the chief complaints of thin stool and lower pelvic heaviness. A smooth, round huge palpable mass on the right posterolateral rectal wall was detected and pelvic computed tomography showed a 7.

Thirty-Day Readmission After Elective Colorectal Surgery for Colon Cancer: A Single-Center Cohort Study.

Purpose: There is a concern that enhanced recovery after surgery may affect other proposed quality measures, including the rate of readmission due to early discharge. We examine the 30-day readmission rate, risk factors associated with readmission after elective colorectal surgery for colon cancer, causes of readmission, disease-free survival (DFS), and overall survival (OS) in a single institution.

Methods: We retrospectively investigated 292 patients who underwent elective colorectal surgery for colon cancer between 2010 and 2015.

The outcome of primary tumor resection in the unresectable stage IV colorectal cancer patients who received the bevacizumab-containing chemotherapy.

Primary tumor resection (PTR) for unresectable metastatic colorectal cancer (mCRC) patients has been documented to be associated with postoperative hyper-neovascularization and enhanced growth of metastases, which may be prevented by bevacizumab. This study aimed to investigate the survival outcome of PTR in patients who received palliative bevacizumab-containing chemotherapy (BCT).From January 2006 to December 2018, medical records of 240 mCRC patients who received palliative BCT at a single tertiary colorectal cancer center were retrospectively reviewed.

Purpose: There are known differences in embryology, clinical symptoms, incidences, molecular pathways involved, and oncologic outcomes of right-sided and left-sided colorectal cancers. However, immunologic study has only been characterized for healthy adults. The present study was designed to identify differences in immune cell populations in patients with right-sided and left-sided colorectal cancers.

Comparison of Right-side and Left-side Colon Cancers Following Laparoscopic Radical Lymphadenectomy.

Purpose: The colon originates from the midgut and hindgut, with subsequent differentiation into the right and left colon. The embryology, clinical symptoms, incidence, molecular pathways, and oncologic outcomes differ between right and left colorectal cancers. However, the differences have not been fully accepted.
