Accuracy of endoscopic ultrasound in rectal cancer and its use in transanal endoscopic microsurgery.

This study evaluated the accuracy of endoscopic ultrasound (EUS) for preoperative staging of rectal cancer and guiding the treatment of transanal endoscopic microsurgery (TEM) in early rectal cancer. One-hundred-twenty-six patients with rectal cancer were staged preoperatively using EUS and the results were compared with postoperative histopathology results. Radical surgeries, including low anterior resection (LAR), abdominal-perineal resection (APR) and Hartmann surgeries, were performed on patients with advanced rectal cancers, and TEM was performed on patients with stage T1.

Madelung's Disease: Is Insobriety the Chief Cause?

Background: Madelung's disease (MD) is a rare disease of unknown etiology that is characterized by massive fatty deposits distributed in a symmetrical pattern mainly in the head, neck, and upper trunk. Here, we sought to explore the pathogeny and treatment of MD.

Methods: We enrolled ten patients who underwent surgical operations and one patient who refused an operation at our hospital between January 2009 and December 2016.

Rupture of sigmoid colon caused by compressed air.

Compressed air has been generally used since the beginning of the 20(th) century for various applications. However, rupture of the colon caused by compressed air is uncommon. We report a case of pneumatic rupture of the sigmoid colon.

Spontaneous perforation of pyometra presenting as acute abdomen: a rare condition with considerable mortality.

Pyometra is an uncommon and potentially lethal disease that occurs mainly in postmenopausal women. Spontaneous perforation of pyometra presenting as acute abdomen is an extremely rare complication of pyometra, and the patients are always admitted to the emergency department. An additional case is reported herein.

[Expression of ZBTB8A in gastric cancer and its clinical significance].

Objective: To investigate the expression of ZBTB8A (zinc finger and BTB domain containing 8A) in gastric cancer tissues and its clinical significance.

Methods: Level of ZBTB8A mRNA in human normal gastric cell line GES-1, human gastric cancer cell line SGC7901 and MGC803 was detected by real-time PCR. Levels of ZBTB8A mRNA and protein in cancer tissues, adjacent cancer tissues from 104 cases with primary gastric cancer and normal gastric mucosal tissues from 40 cases without malignant gastric diseases were detected by RT-PCR and immunohistochemistry, respectively.

[Analysis of the protein expression and gene amplification of HER2 in gastric cancer].

Objective: To explore the clinical significance of protein expression and gene amplification of HER2 in gastric cancer.

Methods: Immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH) method were used to detect protein expression and gene amplification of HER2 in 80 specimens of gastric cancer patients.

Results: Protein expression of HER2 was negative in 51 cases, (+) in 12 cases, (++) in 12 cases, (+++) in 5 cases, and the positive expression rate was 21.

[Analysis of prognostic factors for gastric stump cancer].

Objective: To investigate the independent prognostic factors of long-term survival for gastric stump cancer after radical resection.

Methods: The clinicopathological and follow-up data of 63 patients with gastric stump cancer undergoing surgical treatment from January 1996 to December 2006 in our hospital were analyzed retrospectively, including age, gender, types of reconstruction, tumor location, histological types, TNM stages, surgical treatment, prognosis and etc. The survival was estimated using Kaplan-Meier method and compared using log-rank test.

[Surgical treatment and prognostic factors for obstructing left colorectal cancer].

Objective: To investigate the outcomes of surgical treatment and the prognostic factors of long-term survival for obstructing left colorectal cancer.

Methods: Clinicopathological and follow-up data of 93 patients with obstructing left colorectal cancer undergoing surgical treatment from January 2001 to December 2006 in the Affiliated Hospital of Medical College of Qingdao University were analyzed retrospectively.

Results: There were 53 males and 40 females.
