Colonic leiomyosarcoma with lung metastasis or lung cancer: A case report.

Colonic leiomyosarcoma is a tumor with a very low incidence and a high metastasis rate, mainly lung metastasis. This report provides insights into the future treatment. Thoracic puncture is necessary for patients with pulmonary nodules.

The safety and short-term effect of mixed approach in laparoscopic right hemicolectomy for right colon cancer compared with middle approach: a retrospective study.

Purpose: To investigate whether the mixed approach is a safe and advantageous way to operate laparoscopic right hemicolectomy.

Methods: A retrospective study was performed on 316 patients who underwent laparoscopic right hemicolectomy in our center. They were assigned to the middle approach group (n = 158) and the mixed approach group (n = 158) according to the surgical approaches.

Serum and peritoneal biomarkers for the early prediction of symptomatic anastomotic leakage in patients following laparoscopic low anterior resection: A single-center prospective cohort study.

Background: Anastomotic leakage (AL) is one of the common complications after rectal cancer surgery. This study aimed to evaluate the combination of biomarkers for the early prediction of symptomatic AL after surgery.

Methods: A prospective cohort study evaluated the serum and peritoneal biomarkers of patients who underwent laparoscopic low anterior resection (Lap LAR) from November 1, 2021, to May 1, 2022.

Effect of the transanal drainage tube on preventing anastomotic leakage after laparoscopic surgery for rectal cancer: a systematic review and meta-analysis.

Purpose: Anastomotic leakage (AL) is a common postoperative complication of rectal cancer, and transanal drainage tube (TDT) efficacy is still contentious. This study aimed to evaluate the TDT effect on AL prevention.

Methods: All relevant papers were searched by using a predefined search strategy (two randomized controlled trials (RCTs), one prospective study, and four retrospective studies).

Peritoneal Cytokines as Early Biomarkers of Colorectal Anastomotic Leakage Following Surgery for Colorectal Cancer: A Meta-Analysis.

Background: Postoperative colorectal anastomotic leakage (CAL) is a devastating complication following colorectal resection. However, the diagnosis of anastomotic leakage is often delayed because the current methods of identification are unable to achieve 100% clinical sensitivity and specificity. This meta-analysis aimed to evaluate the predictive value of peritoneal fluid cytokines in the detection of CAL following colorectal surgery.

Comparison of neoadjuvant chemotherapy followed by surgery vs. surgery alone for locally advanced gastric cancer: a meta-analysis.

Background: The neoadjuvant chemotherapy is increasingly used in advanced gastric cancer, but the effects on safety and survival are still controversial. The objective of this meta-analysis was to compare the overall survival and short-term surgical outcomes between neoadjuvant chemotherapy followed by surgery (NACS) and surgery alone (SA) for locally advanced gastric cancer.

Methods: Databases (PubMed, Embase, Web of Science, Cochrane Library, and Google Scholar) were explored for relative studies from January 2000 to January 2021.

Extralevator abdominoperineal excision versus abdominoperineal excision for low rectal cancer: a meta-analysis.

Background: Extralevator abdominoperineal excision (ELAPE) has become a popular procedure for low rectal cancer as compared with abdominoperineal excision (APE). No definitive answer has been achieved whether one is superior to the other. This study aimed to evaluate the safety and efficacy of ELAPE for low rectal cancer with meta-analysis.

[Analysis of risk factors for pulmonary metastasis after curative resection of colorectal cancer].

Objective: To explore the risk factors for pulmonary metastasis after curative resection of colorectal cancer in order to improve the effectiveness of follow-up and the rate of early diagnosis for the high-risk patients.

Methods: The clinicopathological and follow-up data of 268 patients with colorectal cancer undergoing radical resection from January 2004 to December 2006 in the Beijing Cancer Hospital were analyzed retrospectively. Patients were divided into study group including 16(6.

[Application of transorally inserted anvil (OrVil(TM)) in laparoscopic-assisted radical resection for Siewert type II adenocarcinoma of the esophagogastric junction].

Objective: To study the safety and feasibility of transorally inserted anvil (OrVil(TM)) in laparoscopic-assisted radical resection for Siewert type II adenocarcinoma of the esophagogastric junction (AEG).

Methods: Clinical data (operative time, rate of thoracotomy, residual cancer in the proximal margin, and postoperative recovery) of 72 patients suffered from Siewert type II AEG were analyzed retrospectively, including 46 cases of applying OrVil(TM) in digestive tract reconstruction for laparoscopic-assisted radical resection and 26 cases of applying pouch clamp embedding anvil, between May 2009 and August 2012 in Department of Minimally Invasive Gastrointestinal Surgery at the Peking University Cancer Hospital and Institute.

Results: The length between proximal margin and superior border of tumor was (2.

[Application of matrix assisted laser desorption ionization-time of flight-mass spectrometry in detecting K-ras gene mutation of colorectal cancer].

Objective: To investigate the clinical value of matrix assisted laser desorption ionization-time of flight-mass spectrometry (MALDI-TOF-MS) in detecting K-ras gene mutation.

Methods: Sixty-one paraffin-embeded specimens of colorectal cancer were selected. MALDI-TOF-MS and regular sequencing were used to test the mutation of codon 12 and 13 in K-ras exon 2.

[Recent advances and some consideration about laparoscopic surgery in patients with gastric cancer].

Laparoscopy-assisted distal gastrectomy for gastric cancer was first reported in 1994. Since then, the laparoscopic approach is rapidly becoming the preferred method of treatment for patients with early gastric cancer (EGC) due to the many advantages of minimally invasive surgery. Many retrospective comparative trials and randomized-controlled trials (RCT) have confirmed that laparoscopic gastrectomy (LG) is safe and feasible, and that short-term outcomes are better than those of open gastrectomy in patients with EGC.

D2 dissection in laparoscopic and open gastrectomy for gastric cancer.

Aim: To evaluate the radicalness and safety of laparoscopic D2 dissection for gastric cancer.

Methods: Clinicopathological data from 209 patients with gastric cancer, who underwent radical gastrectomy with D2 dissection between January 2007 and February 2011, were analyzed retrospectively. Among these patients, 131 patients underwent laparoscopy-assisted gastrectomy (LAG) and 78 underwent open gastrectomy (OG).
