Application of double circular suturing technique (DCST) in repair of giant incision hernias.

Background: Our study aims to explore the feasibility and safety of a double circular suturing technique (DCST) in the repair of giant incision hernias.

Methods: The clinical data of 221 patients (95 men and 126 women; the average age was 61.6 years) receiving DCST in the repair of giant incision hernia between January 2010 and December 2018 was analyzed retrospectively.

Application of double circular suturing technique (DCST) in the repair of large abdominal wall defects after resection of abdominal wall tumor.

Background: The aim of this study was to investigate the clinical effects of repairing large defects using the double circular suturing technique (DCST) after resection of abdominal wall tumor.

Methods: The clinical data of 62 patients (25 men, 37 women; average age 41.7±22.

[Expression of phosphatase of regeneration liver-3 in human colorectal carcinoma and its prognosis value].

Objective: To investigate the expression of phosphatase of regeneration liver-3(PRL-3) protein and its relationship with tumor invasion and metastasis in human colorectal carcinoma,and elucidate prognostic value.

Methods: Immunohistochemistry method was applied to detect the PRL-3 expression in the primary tumor specimens and paired paratumor normal tissues from 46 colorectal carcinoma patients, the adenoma tissues from 6 patients with colorectal adenoma, all the metastatic lymph nodes from 29 cases and the metastatic liver lesions from 6 cases. The relationship between PRL-3 expression and clinicopathologic parameters was analyzed and a survival curve was achieved according to Kaplan-Meier method.

[Lateral pelvic metastasis and micrometastasis in low rectal cancer].

Objective: To study lateral pelvic metastasis and micrometastasis of low rectal cancer and elucidate their prognostic value.

Methods: Whole-mount slice and tissue microarray of dissected lateral pelvic specimen from 67 cases of low rectal cancer were examined, and the included cases were followed up.

Results: Twelve specimens were diagnosed as lateral metastasis, while another 10 were proved to bear micrometastasis.

Distribution and patterns of lymph nodes metastases and micrometastases in the mesorectum of rectal cancer.

Background And Objectives: Facts buried in the mesorectum remain to be unveiled. This study investigated the number, size, and detailed distribution of lymph nodes metastases and micrometastases within the mesorectum of rectal cancer.

Methods: Thirty-one patients who underwent total mesorectal excision (TME) were treated with lymph node revealing solution to retrieve lymph nodes, which were submitted to hematoxylin and eosin (HE) examination and immunohistochemical (IHC) staining.

[Expression of phosphatase of regenerating liver-3 mRNA and its clinical implications in human colorectal carcinoma].

Objective: To investigate the expression of phosphatase of regenerating liver-3 (PRL- 3) mRNA and evaluate its relationship with tumor invasion and metastasis in human colorectal carcinoma.

Methods: The expression level of PRL-3 mRNA was examined semi-quantitatively in surgically resected tumor specimens, paired paratumor normal tissues from 46 CRC patients, metastatic lymph nodes and liver metastases from 18 cases with metastasis,adenoma tissues from 6 patients with colorectal adenoma (CRA). In addition,the mutation of PRL-3 gene was examined by PCR-SSCP.

[Evaluation of clinical necessity of gastrointestinal decompression after excision and anastomosis of lower digestive tract].

Objective: To evaluate the clinical necessity of postoperative gastrointestinal decompression after operation on lower digestive tract.

Methods: Three hundred and sixty-eight patients who required excision and anastomosis of lower digestive tract were randomly divided into two groups, with or without receiving gastrointestinal decompression after operation. Clinical therapeutic efficacy and complications were compared between two groups.

Pathological study of distal mesorectal cancer spread to determine a proper distal resection margin.

Aim: Local recurrence after curative surgical resection for rectal cancer remains a major problem. Several studies have shown that incomplete removal of cancer deposits in the distal mesorectum contributes a great share to this dismal result. Clinicopathologic examination of distal mesorectum in lower rectal cancer was performed in the present study to assess the incidence and extent of distal mesorectal spread and to determine an optimal distal resection margin in sphincter-saving procedure.

Gastrointestinal decompression after excision and anastomosis of lower digestive tract.

Aim: To discuss the clinical significance of postoperative gastrointestinal decompression in operation on lower digestive tract.

Methods: Three hundred and sixty-eight patients with excision and anastomosis of lower digestive tract were divided into two groups, i.e.

Laparoscopic total mesorectal excision of low rectal cancer with preservation of anal sphincter: a report of 82 cases.

Aim: To assess the feasibility and efficacy of laparoscopic total mesorectal excision (LTME) of low rectal cancer with preservation of anal sphincter.

Methods: From June 2001 to June 2003, 82 patients with low rectal cancer underwent laparoscopic total mesorectal excision with preservation of anal sphincter. The lowest edge of tumors was below peritoneal reflection and 1.
