[Therapeutic effect of excision of hypomere esophagus and proximal stomach on portal hypertension and upper gastrointestinal bleeding].

OBJECTIVE: To analyze the therapeutic effect of excision of hypomere esophagus and proximal stomach (Phemister operation) on portal hypertension and upper gastrointestinal bleeding. METHODS: Retrospectively analyze the clinical data of 136 cases treated with the Phemister operation for portal hypertension and upper gastrointestinal bleeding from August 1999 to May 2005. RESULTS: Varication of the patients improved markedly, 50.8% of the varication disappeared completely, incidence of complications was 5.0%, rebleeding rate was 4.4%, mortality rate was 0.7%. CONCLUSIONS: The Phemister operation could treat the upper gastrointestinal bleeding and prevent rebleeding effectively in portal hypertension, it is a radical, precise and secure disconnection for portal hypertension with varication in fundus of stomach and esophagus.

[Endoscopic thyroid surgery: a comparison of the trans-subclavian and the trans-areolar approach].

OBJECTIVE: To compare the advantages and shortcomings of the endoscopic thyroid surgery by trans-subclavian approach and trans-areolar approach. METHODS: Twelve patients received the trans-areolar approach and 10 patients were given the trans-subclavian approach procedure. RESULTS: With the trans-areolar approach: the mean size of tumor was 1.8 cm, the mean operating time was 115 min, the mean blood loss during operation was 63 ml. Two patients converted to the conventional operation. With the trans-subclavian procedure: the mean size of tumor was 4.2 cm, the mean operating time was 85 min, the mean blood loss during operation was 66 ml. No complications were found in all of the patients and they were satisfied with the cosmetic effects of the procedures. There were significant differences in tumor size and operating time between the two operation types. CONCLUSIONS: Compared with the trans-areolar approach, the trans-subclavian approach comes with less trauma, higher success rate and it fits for bigger tumor.

[Thyroid nodules with calcification and thyroid carcinoma].

OBJECTIVE: To investigate the significance of thyroid calcification for diagnosis of thyroid carcinoma. METHODS: Retrospective analysis of 817 thyroid nodules' pre-operative ultrasonic and postoperative pathologic results. RESULTS: Total ultrasonic thyroid calcification ratio was 18.1% (148/817). Total pathologic thyroid calcification ratio was 19.6% (160/817), which in benign samples was lower than that in malignant samples (13.1% vs 53.5%, P < 0.01). Micro-calcification ratio in benign samples was lower than that in malignant samples (2.9% vs 38.6%, P < 0.01). CONCLUSIONS: Thyroid nodules with calcification especially micro-calcification is considered to be the most specific sign of thyroid carcinoma, so the detection of it should be an important diagnostic criterion.
