Robotic gastrectomy is more beneficial for advanced than early-stage gastric cancer: a comparison with laparoscopic gastrectomy using propensity score matching.

Background: Gastric cancer is the fifth most prevalent malignancy globally and the fourth major contributor to cancer-related mortality. The comparative effectiveness of robotic gastrectomy (RG) versus laparoscopic gastrectomy (LG) at different stages of gastric cancer is unclear regarding surgical and survival outcomes. We compared surgical and survival outcomes between RG and LG in early-stage (cStage I) and advanced (cStage II/III) gastric cancers to elucidate the difference in the efficacy of RG across various stages of gastric cancer.

Macroscopic type is implicated in the prognostic impact of initial chemotherapy on peritoneal lavage cytology-positive gastric cancer with no other noncurative factors.

Background: Initial chemotherapy (Initial-C) followed by surgery is a promising treatment strategy for peritoneal lavage cytology-positive gastric cancer (CY1 GC) with no other noncurative factors. The aim of this study was to investigate the survival advantage of Initial-C compared to initial surgery (Initial-S) for this disease according to the macroscopic type, which was associated with prognosis and the efficacy of chemotherapy in GC.

Methods: One hundred eighty-nine patients who were diagnosed with CY1 GC with no other noncurative factors at four institutions from January 2007 to December 2018 were enrolled.

Comparison of Surgical and Oncological Outcomes of Laparoscopic and Open Gastrectomy for Pathologically Serosa-Invasive (pT4a) Advanced Gastric Cancer-Retrospective Propensity Score-Matched Analysis.

We aimed to clarify the operative feasibility and oncological efficacy of a laparoscopic gastrectomy (LG) for pT4a gastric cancer through comparison with open gastrectomy (OG). We compared surgical and oncological outcomes in 178 patients with pT4a gastric cancer who underwent LG or OG between 2002 and 2016; the background was adjusted using propensity score matching. After score matching, 45 patients were included in each group.

Is radiological psoas muscle area measurement a predictor of postoperative complications after rectal resection for rectal cancer? A retrospective study.

Purpose: Previous studies have reported that sarcopenia increases the risk of postoperative complications following colorectal resection. This retrospective study assessed the postoperative complications of rectal resection associated with sarcopenia.

Methods: We retrospectively analyzed 262 patients who underwent curative low anterior resection for primary rectal cancer from January 2008 to May 2020 at our institution.

Ileo-right colonic reconstruction preserving all four colonic vessels after esophagectomy for cancer.

When colonic graft is used as an esophageal substitute after esophagectomy, one or two feeding vessels of the colon are cut to obtain sufficient length, the graft is passed via the subcutaneous route, and microvascular anastomosis is often used to avoid fatal complications. Sixteen consecutive ileo-right colonic reconstructions via the posterior mediastinal or retrosternal route with preservation of all four colonic vessels were performed in the past eight years. We presented the surgical technique and evaluation of this surgical method.

Comparison of surgical smoke between open surgery and laparoscopic surgery for colorectal disease in the COVID-19 era.

Background: Surgical smoke during operation is a well-known health hazard for medical staff. This study aimed to investigate the dynamics of surgical smoke during open surgery or laparoscopic surgery for colorectal disease.

Methods: This study quantitated particulate matter (PM) counts as part of surgical smoke in 31 consecutive patients who underwent colectomy at the Niigata City General Hospital using a laser particle counter.

Influence of Suture Materials on Incisional Hernia Rate after Laparoscopic Colorectal Cancer Surgery: A Propensity Score Analysis.

Objectives: Incisional hernia is a common problem after colorectal surgery, and a laparoscopic approach does not reduce the incisional hernia rate. Previous reports have described the risk factors for incisional hernia; however, the impact of suture materials remains unclear. As such, this study compared the incisional hernia rate using different suture materials for abdominal wall closure after laparoscopic colorectal cancer surgery.

Gastrointestinal stromal tumor of the stomach with lymph node metastasis treated by laparoscopic and endoscopic cooperative surgery with lymph node pick-up resection: A case report and literature review.
