Application of meticulous anatomy skills with straight bipolar electric coagulation forceps in thyroid surgery / 中华耳鼻咽喉头颈外科杂志

To compare the efficacies of the two techniques of "micro-hemostasis and micro-cutting" with straight bipolar electrocoagulation forceps and traditional clamp-ligation for hemostasia in thyroid surgery. A total of 228 patients who underwent surgical treatment for thyroid neoplasms in our hospital between January 2015 and December 2018 were retrospectively analyzed, including 50 males and 178 females, aged 23-68 years old. Of those, 150 cases as electric knife group received traditional thyroid surgery between January 2015 and December 2018 and 78 cases as bipolar electrocoagulation group received thyroid surgery by using the technique of bipolar electrocoagulation with meticulous anatomy between January 2018 and December 2018. The total operation time, single operation time, intraoperative hemorrhage, postoperative drainage volume on the first day, postoperative hoarseness and hypocalcemia were compared between the two groups. SPSS 16.0 was used to analyze the data. The total operation time and intraoperative hemorrhage in the bipolar electrocoagulation group were significantly lower than those in the electric knife group ((59.33±18.29)min (77.21±25.39)min, (14.83±9.22)ml (36.86±11.80)ml, all 0.01). The single operation time of the bipolar electrocoagulation group was shorter than that of the electric knife group((10.25±6.16) min (20.34±7.24)min, (16.25±7.15)min (35.68±8.25)min, (12.12±5.25)min (20.68±7.26)min, value was 3.948,16.262,8.238, all 0.01).There was no significant difference between the two groups in postoperative drainage volume on the first day (0.05) and the incidence of postoperative hoarseness (0.05), while the incidence of hypocalcemia in the bipolar electrocoagulation group(10.26%) was lower than that in the electric knife group(21.33%,χ(2)=4.353, 0.05). The fine dissection for thyroid operation can be achieved by using straight bipolar electrocoagulation tweezers. The use of "micro-hemostasis" and "micro-cutting" technique with bipolar electrocoagulation tweezers can greatly reduce intraoperative bleeding, operation time and postoperative complication.

Effect of Steaming Time and Pressure on Contents of Six Ginsenosides in Ginseng Radix et Rhizoma by UPLC-QqQ-MS/MS / 中国实验方剂学杂志

Objective::The processing method of red ginseng was determined by comparing the effects of different steaming time and pressure on the total content of six ginsenosides. Method::The contents of ginsenoside Rg1, Re, Rf, Rb1, Rc and Rb2 were determined by ultra high performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-QqQ-MS/MS). The Waters ACQUITY UPLC BEH C8 column (2.1 mm×100 mm, 1.7 μm) was used. The mobile phase was 0.1% formic acid aqueous solution (A) and 0.1% formic acid acetonitrile solution (B) for gradient elution (0-4 min, 81%-79%A; 4-6.3 min, 79%-75%A; 6.3-6.5 min, 75%-71%A; 6.5-9.5 min, 71%A; 9.5-16.5 min, 71%-68.5%A; 16.5-16.6 min, 68.5%-60%A; 16.6-19 min, 60%-100%A). The flow rate was set at 0.4 mL·min-1 and the column temperature was set at 35 ℃. The mass spectrographic analysis employed electrospray ionization (ESI) and negative ion collection mode with capillary ionization voltage of 2.5 kV, desolvation temperature of 350 ℃, desolvation gas flow of 700 L·h-1 and cone gas flow of 50 L·h-1. Multiple reaction monitoring (MRM) mode was used to collect information, the collection range was m/z 100-1 500, detection was performed by MRM mode at m/z 799.59-637.49 for ginsenoside Rg1, m/z 945.54-475.79 for ginsenoside Re, m/z 799.59-475.49 for ginsenoside Rf, m/z 1 107.59-783.97 for ginsenoside Rb1, m/z 1 077.58-783.96 for ginsenoside Rc, m/z 1 077.75-191.19 for ginsenoside Rb2. Result::When the steaming time was 3 hours, the total mass fraction of six ginsenosides in each sample group was 7.099 8-16.768 5 mg·g-1, and the total amount of the six ginsenosides in atmospheric steaming was 2.5-12.6 times of that in pressurized steaming, which was obviously better than that in pressurized steaming. Conclusion::Under the conditions of this experiment, the best processing method of red ginseng is atmospheric steaming for 3 hours with fresh ginseng.

Endoscope-assisted thyroidectomy with minimal incision in neck / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To explore the feasibility of endoscope-assisted thyroidectomy with minimal neck incision.</p><p><b>METHODS</b>Endoscope-assisted thyroid surgeries had been accomplished through incision above sternal notch and in submental area respectively from August 2003 to August 2005, including 11 partial lobectomy, 3 lobectomy, 2 two-sides partial lobectomy, 1 isthmectomy.</p><p><b>RESULTS</b>In this group, 12 cases approached through above sternal notch, 5 cases approached through the submental area, and all were successful. The mean length of incisions was 2.3 cm (range from 1.5 cm to 3.0 cm). No one was converted to open surgery. The mean time of operation was 61.3 minutes (range from 30 minutes to 120 minutes). The mean volume of hemorrhage during the operation was 15.6 ml (range from 10 to 40 ml). The mean volume of drainage of post-operation was 22.5 ml (range from 6 ml to 40 ml). The mean length of stay was 4. 5 days (range from 3 days to 6 days). There were no hoarseness and no low serum calcium. Following visits were performed after operation from 1 month to 12 months, and there were no stiff feelings on skin. The cosmetic outcomes of the incisions were good, except 1 case for scar physique.</p><p><b>CONCLUSIONS</b>Endoscope-assisted thyroidectomy was safe and feasible with good cosmetic outcome. The selection of approach with minimal incision depends on the location of neoplasm.</p>

Diagnosis and reoperation for thyroid carcinoma / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To analysis the reasons of the reoperation of thyroid neoplasm and the efficiency of the surgery and to explore the diagnosis of thyroid neoplasm in order to choose the rational surgical method.</p><p><b>METHODS</b>Reoperation of thyroid cancers were performed in 128 patients from Oct. 1992 to Oct. 2000. The causes of reoperation were thyroid cancer remnants and persistence of the micro carcinoma The type of reoperation includes: 1. completion of lobectomy and isthmectomy or subtotal thyroidectomy. Radical neck dissection or modified neck dissection were indicated for the neck of lymph node metastasis. 2. completion of lobectomy and isthmectomy and modified neck dissection or selective neck dissection for patient with thyroid micro carcinoma. Preoperative fine needle aspiration (FNA) (10 cases), intra-operative frozen section (FS) (55 cases), FNA and FS (13 cases) were done in 78 patients who first visited our hospital, with pure (solitary) thyroid nodule suspected thyroid carcinoma clinically. The results of the above examinations were compared with postoperative pathological results.</p><p><b>RESULTS</b>For the patients with reoperation, the rate of remained cancer was 68.8% (88/128) which was confirmed by pathological results. The occurring of complication was 23.4% (30/128). Laryngeal recurrent nerve paralysis was accounted for 2. 3% and transient postoperative hypocalcemia occurred in 19.5%. Five patients developed local recurrence and 3 had neck metastasis the following up. The 5-, 10-year survival rates of these patients were 92.0% (101/110) and 86.9% (17/20) respectively. The diagnostic accuracy of preoperative FNA, intra-operative FS, FNA and FS were 90.0%, 87.3% and 92.3% respectively.</p><p><b>CONCLUSIONS</b>The rate of postoperative residual carcinoma in thyroid was relatively higher because of misdiagnosis and inadequate operation. It was necessary to take active and reasonable reoperation. Reoperation added to surgical complications. Increasing preoperative diagnostic accuracy & carrying out standard, adequate surgical treatment are the essence to decrease surgical complication.</p>

Clinical study of extranodal NK-T cell lymphoma-nasal type / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To discuss how the diagnosis, misdiagnosis and different treatment modalities affect the prognosis of the patients with extranodal NK-T cell lymphoma-nasal type.</p><p><b>METHODS</b>A retrospective study was made on the clinical characteristics, treatment modality, short-term effect, and survival rate of 68 patients with extranodal NK-T cell lymphoma-nasal type. Among them,60 patients staged I(E) were subdivided into single therapy group of 20 cases( radiation therapy 9 cases, chemotherapy 11 cases) and combined therapy group of 40 cases (9 cases with radiation therapy + chemotherapy, 12 cases with chemotherapy + radiation therapy,19 cases with chemotherapy + radiation therapy + chemotherapy). Eight patients staged IV(E) included 3 cases with radiation therapy alone and 5 cases with chemotherapy and radiation therapy.</p><p><b>RESULTS</b>The rate of misdiagnosis of whole group is 66. 2% (45/68), and the rate of misoperated patients accounted for 52. 9% (36/68). The CR rate of radiation therapy was 94. 4% (17/18) for limited disease in I(E) group compared 61.9% (26/42) for out-cavity disease in I(E) group, of which the difference is significant (P =0. 012). The 1-years, 3-years and 5-years survival rate of the I(E) intra-cavity group were 100%, 77.8%, 59.8%, and those of ex-cavity group were 80.1%, 48.5% and 14.6%, respectively. The 1, 3 and 5-years survival rate of IV(E) group were 17.5%, 0.0% and 0.0%. The difference of survival was significance among the above 3 groups (P = 0. 000). The 1, 3, 5-years survival rate of 60 I(E) patients with single therapy were 68.4%, 22.8% and 7.6% respectively; and that of combined therapy group were 94.9%, 81.1% and 52.4% respectively, which was significant difference (P = 0. 000). The survival difference among the radiation therapy + chemotherapy group, chemotherapy + radiation therapy group and chemotherapy + radiation therapy + chemotherapy group were not significant (P = 0.088).</p><p><b>CONCLUSIONS</b>The early clinical manifestation of extranodal NK-T cell lymphoma-nasal type is not typical,which is easy to be misdiagnosed and mistreated. Early therapy is the key,which can achieve good location control. Diseased stage I(E) out-cavity and above should be treated with combined therapy.</p>
