Intraluminal washout in rectal and sigmoid colon cancer surgeries with double-stapling technique anastomosis: A single-institution prospective study.

Aim: This study aimed to determine the necessity of intraluminal washout through cytological assessment to prevent implantation of exfoliated cancer cells (ECCs) in patients with rectal and sigmoid cancers.

Methods: We studied 140 patients with either sigmoid or rectal cancer who underwent anastomosis surgery using a double-stapling technique. An intraluminal washout sample was collected before and after irrigation with 1000, 1500, or 2000 mL of physiological saline or distilled water.

Impact of postoperative infectious complications on long-term prognosis after esophagectomy.

Background: Postoperative complications have been reported to be a risk factor for worse oncologic outcomes in patients with esophageal cancer. However, the impact of postoperative complications on prognosis after esophagectomy remains controversial. We aimed to investigate the factors that influence the prognosis of postoperative complications in patients who underwent oncological esophagectomy, focusing on chronic obstructive pulmonary disease (COPD).

New Surgical Criteria for Intraductal Papillary Mucinous Neoplasm Based on the Age-Adjusted Charlson Comorbidity Index Values and Presence of Solid Component.

: The present study aimed to validate the new international guidelines for IPMN and determine the surgical criteria for patients with IPMN exhibiting high-risk stigmata (HRS). : We enrolled 115 IPMN patients exhibiting HRS who were diagnosed between 2004 and 2021. Of the 115 patients, 79 underwent surgery (surgical group) and 36 did not undergo surgery (non-surgical group).

Prognostic significance and risk factors of mediastinal lymph node metastasis in esophagogastric junction cancer: a single-center, retrospective study.

Background: Although the optimal extent of lymph node dissection in esophagogastric junction cancer (EGJC) has been reported, the efficacy of mediastinal lymph node dissection remains unclear. We aimed to identify risk factors for mediastinal lymph node metastasis and its prognostic impact in patients with EGJC.

Methods: A total of 100 consecutive patients who underwent curative surgery for EGJC were eligible.

Inter-prefectural regional disparities in gastric cancer surgery: A Japanese nationwide population-based cohort study from 2014 to 2019.

Aim: This study aimed to investigate the regional disparities in gastric cancer surgery in Japan.

Methods: The annual incidence of gastric cancer and number of gastrectomies, board-certified surgeons in gastroenterology by the Japanese Society of Gastroenterological Surgery, and board-certified surgeons by the Japan Society for Endoscopic Surgery were evaluated by prefecture in Japan during 2014-2019. Medium-sized regional disparities were assessed using the Gini coefficient.
