Preoperative difficulty factors in delayed laparoscopic cholecystectomy: Tokyo Guidelines 2018 surgical difficulty score analysis.

Introduction: Tokyo Guidelines 2018 (TG18) recommend early laparoscopic cholecystectomy (LC) for low-risk acute cholecystitis (AC); however, some patients undergo delayed LC (DLC) after conservative treatment. DLC, influenced by chronic inflammation, is a difficult procedure. Previous studies on LC difficulty lacked objective measures.

[Two Cases of Stage Ⅳ Colorectal Cancer with Long-Term Survival following Single-Agent Chemotherapy with Capecitabine-A Case Reports].

We experienced 2 cases of Stage Ⅳ colorectal cancer obtained long-term survival by chemotherapy with only capecitabine. Case 1: Seventy-one-years-old male was performed open sigmoid colectomy, D2 dissection for sigmoid colon cancer. Pathological diagnosis was pT4aN2aM0, pStage Ⅲc.

Total Steroid Intake is Associated With Hospital Mortality in Patients With Pan-Peritonitis due to Colorectal Perforation.

Background: Patients with pan-peritonitis (PP) due to colorectal perforation have high mortality rate because colorectal perforation causes septic shock. The association between total steroid intake (TSI) and hospital mortality of such patients is not clear.

Methods: One hundred forty-two patients who underwent surgery for PP due to colorectal perforation were reviewed.

Laparoscopic surgery reduced frequency of postoperative small bowel obstruction, and hospital stay compared with open surgery in a cohort of patients with colorectal cancer: a propensity score matching analysis.

Background: Laparoscopic surgery (LS) is reported to reduce postoperative complications and hospital stay compared with open surgery (OP). Because patient selection may have been biased in previous studies, propensity score matching (PSM) analysis was used in this study to test the benefits of LS compared with OP.

Methods: A total of 759 patients with stage I-III colorectal cancer undergoing curative surgery were retrospectively reviewed.

The preoperative pan-immune-inflammation value is a novel prognostic predictor for with stage I-III colorectal cancer patients undergoing surgery.

Purpose: The pan-immune-inflammation value (PIV) is useful for stratifying outcomes in patients with metastatic colorectal cancer. However, it is unclear whether preoperative PIV can predict the surgical outcomes of patients with stage I-III colorectal cancer who receive surgery.

Methods: The records of 758 patients with stage I-III colorectal cancer who received surgical treatment were retrospectively reviewed.

Appendectomy Does Not Increase the Risk of Future Emergence of Parkinson's Disease: A Meta-analysis.

Objective: To explore the impact of appendectomy history on emergence of Parkinson's disease (PD).

Background: Although there are several studies to investigate the relationship between appendectomy history and emergence of PD, the results are still controversial.

Methods: We performed a comprehensive electronic search of the literature (the Cochrane Library, PubMed, and the Web of Science) up to April 2020 to identify studies that had employed databases allowing comparison of emergence of PD between patients with and those without appendectomy history.

Impact of Primary Tumor Location on Survival After Curative Resection in Patients with Colon Cancer: A Meta-Analysis of Propensity Score-Matching Studies.

Background: Recent retrospective subgroup analyses of patients with unresectable colon cancer (CC) receiving systemic chemotherapy have demonstrated that there is a significant difference in treatment outcome between patients with right-sided CC (RSCC) and those with left-sided CC (LSCC). However, it is impossible to divide patients with CC randomly into RSCC and LSCC groups before surgery. Therefore, the aim of this study is to explore the impact of primary tumor location (PTL) on survival after curative surgery for patients with CC using propensity score-matching (PSM) studies instead of randomization.
