Prognostic impact of postoperative management by an intensive care unit intensivist after colonic perforation.

Purpose: Postoperative management for colonic perforation is an important prognostic factor, but whether intensivists perform postoperative management varies between institutions.

Methods: We investigated 291 patients with colonic perforation between 2018 and 2022. Patients were divided into those managed by an intensivists (ICU group; n = 40) and those not managed by an intensivists (non-ICU group; n = 251).

Laparoscopic colectomy for patients with poor American Society of Anesthesiology classifications.

Introduction: The American Society of Anesthesiologists (ASA) classification is used to assess the fitness of a patient for surgery. Whether laparoscopic surgery is appropriate for colorectal cancer patients with poor ASA performance status (PS) remains unclear.

Methods: Among 4585 patients who underwent colorectal surgery between 2016 and 2023, this study retrospectively reviewed all 458 patients with ASA-PS ≥3.

The C-reactive protein-albumin-lymphocyte (CALLY) index is a useful predictor of postoperative complications in patients with a colonic stent for obstructive colorectal cancer: a Japanese multicenter study.

Purpose: The C-reactive protein-albumin-lymphocyte (CALLY) index is a novel score that offers a good reflection of nutritional status, inflammatory response, and immune system status. The CALLY index is reported to correlate with the prognosis of various carcinomas. The purpose of the present study was to investigate the association between the CALLY index and the short-term prognosis of obstructive colorectal cancer managed with a colonic stent.

Effect of the lymphocyte-to-monocyte ratio on the prognosis of patients with obstructive colorectal cancer with a colonic stent: a retrospective multicenter study in Japan.

Purpose: The prognostic value of the lymphocyte-to-monocyte (LMR) ratio has been reported for various cancers, including colorectal cancer (CRC). The insertion of colonic stents is considered effective for patients with surgically indicated obstructive CRC, but their LMR can vary depending on factors such as inflammation associated with stent dilation and improvement of obstructive colitis. However, the usefulness of the LMR in patients with obstructive CRC and colonic stents and the optimal timing for its measurement remain unclear.

Risk factors for pulmonary complications after colorectal cancer surgery: a Japanese multicenter study.

Purpose: Pulmonary complications (PC) are a serious condition with a 20% mortality rate. However, few reports have examined risk factors for PC after colorectal surgery. This study investigated the frequency, characteristics, and risk factors for PC after colorectal cancer surgery.

Short- and Long-term Outcomes After Colonic Stent Insertion as a Bridge to Surgery in Elderly Colorectal Cancer Patients.

Background/aim: Colonic stents have been inserted as a bridge to surgery in patients with resectable colorectal cancer, allowing bowel decompression for systemic assessment and better preparation to avoid stoma construction. However, reports of short- and long-term prognoses for elderly patients remain limited.

Patients And Methods: This retrospective study reviewed 175 consecutive patients who underwent colonic stent insertion for bowel obstruction followed by curative colectomy.

Prognostic value of lymph node distribution after laparoscopic colectomy with Japanese D3 dissection.

Purpose: Positive pathologic lymph nodes in colorectal cancer represent an important prognostic indicator. Whether lymph node distribution or the number of metastatic nodes is more strongly associated with survival prediction remains controversial.

Methods: Among 3449 colorectal cancer surgeries performed at Nagasaki University Hospital and five affiliated institutions from April 2016 to March 2022, we investigated 604 patients who underwent laparoscopic radical resection and were diagnosed with pathological stage III cancer.

Usefulness of the endoscopic surgical skill qualification system for laparoscopic colectomy for transverse colon cancer: a Japanese multicenter analysis.

Purpose: Laparoscopic colectomy for transverse colon cancer (TCC) can be technically demanding due to the anatomical complexity of the region. In Japan, the Endoscopic Surgical Skill Qualification System (ESSQS) was established to improve the skill of laparoscopic surgeons and further develop surgical teams. We examined the safety and feasibility of laparoscopic colectomy for TCC and evaluated the effects of the Japanese ESSQS in facilitating this approach.

Colorectal cancer in Crohn's disease: a series of 6 cases.

Background: Colorectal cancer (CRC) is the most malignant complication in patients with Crohn's disease (CD). We report 6 cases of CD-related CRC treated surgically at our hospital.

Case Presentation: From 2010 to 2016, six CD patients were diagnosed with CRC.

Single-incision laparoscopic total colectomy using an organ retractor: A case report.

Introduction: Single-incision laparoscopic surgery (SILS) has benefits, including less postoperative pain, a shorter incision, and improved cosmesis. However, SILS is technically difficult because of the limited movement. An organ retractor is an instrument that has the potential to overcome these limitations.
