BACKGROUNDEndoscopic submucosal dissection of the esophagogastric junction is the most difficult gastric and esophageal dissection procedure. No reports of endoscopic submucosal dissection for Siewert type II carcinoma of the esophagogastric junction have compared the outcomes of endoscopic submucosal dissection for all three Siewert types of adenocarcinoma. This study aimed to evaluate the efficacy and safety of endoscopic submucosal dissection for intraepithelial neoplasia of the esophagogastric junction.
METHODSFrom October 2008 to June 2013, 73 patients underwent endoscopic submucosal dissection for intraepithelial neoplasia of the esophagogastric junction. The patients were prospectively evaluated regarding the executability of the technique, short-term results of the procedure, en bloc resection rate, curative resection rate, complications and additional treatment after endoscopic submucosal dissection, and follow-up outcomes.
RESULTSSixty-eight of the 73 patients (93.2%) underwent en bloc resection; the mean maximum specimen diameter was 33.7 mm. Fifty-seven of 61 patients (93.4%) who underwent curative resection were successfully followed-up for 1.0 to 56.0 months (average, 24.1 months). Local recurrence developed in one patient with high-grade intraepithelial neoplasm. Twelve patients underwent noncurative resection, including lateral resection margin residues in three, vertical resection margin residues in one, signet ring cell carcinoma or undifferentiated adenocarcinoma in four, lymphatic or vessel invasion in one, vertical residual margin residues combined with signet ring cell carcinoma in one, and undifferentiated adenocarcinoma with lymphatic or vessel invasion in two. In the noncurative resection group, one patient was lost to follow-up, seven underwent additional surgery, and the remaining four were periodically followed up; none had local recurrence or distant metastases. The only complication was delayed bleeding in three patients, which was successfully controlled by conservative treatment or endoscopic therapy.
CONCLUSIONSEndoscopic submucosal dissection is safe and effective for intraepithelial neoplasia of the esophagogastric junction. R0 en bloc resection is possible and can avoid the risk of local recurrence.

OBJECTIVETo approach reasonable operational mode of differentiated thyroid cancer.
METHODSRetrospectively review 546 differentiated thyroid cancer patients who received bilateral thyroidectomy with or without cervical lymph node excision from January 2001 to December 2006.
RESULTSNo death case happened during operation and hospitalization. The positive percentage of cervical lymph node metastasis was 76.2% (358/470). The incidence rate of single lateral recurrent laryngeal nerve injury was 1.1% (6 cases), parathyroid gland partly injury was 0.4% (2 cases), superior laryngeal nerve injury was 0.7% (4 cases), bleeding was 0.6% (3 cases) and esophagus injury after operation was 0.2% (1 case). There were no bilateral recurrent laryngeal nerve injury found.
CONCLUSIONSTotal thyroidectomy is an essential operational mode for differentiated thyroid cancer. It is necessary to excise cervical lymph node when the tumor's diameter exceeds 1 cm.

OBJECTIVETo evaluate the regional anatomy between the abdominal autonomic nerves including the abdominal aortic plexus (AAP) and the inferior mesenteric artery (IMA), and explore the safe ligation point on the IMA and the optimal dissection method to avoid autonomic nerve injuries.
METHODS AND RESULTSDissections and observation were carried out on 16 fixed male cadavers. The AAP located in the thin fascia layer covering the surface of the aorta and its branches. No autonomic nerves were found in the area around the root of the IMA, and the point where the IMA and the left trunk of the AAP intersected was highly variable. The left trunk of the AAP adhered more closely to the IMA than to the aorta.
CONCLUSIONSIn view of autonomic nerve preservation, the only safe site for ligation of the IMA is at its origin, and no other such sites are available along the IMA trunk and its branches. The IMA and the posterior fascia layer containing the autonomic nerves constitute the optimal surgical plane for IMA ligation, which should be performed following skeletonization of the IMA with careful preservation of the integrity of the posterior fascia layer.

OBJECTIVETo study the surgical management of fatal hemorrhage following head and neck surgery for cancer.
METHODSThe clinical data of 32 cases of fatal hemorrhage following head and neck surgery from 1976 to 2008 in our department were analyzed retrospectively.
RESULTSHemorrhage was caused by carotid blowout in 20 cases. The carotid ligation was performed in 13 cases, only 6 cases got long-term survival. In 12 cases, hemorrhage was caused by tracheo-innominate artery fistula, only 2 cases received surgical management, and no long-term survivors.
CONCLUSIONFatal hemorrhage following head and neck surgery is an uncommon but frequently fatal complication, and the successful management of it depends on early diagnosis and correct treatment.

OBJECTIVETo explore a cosmetic incision in the neck dissection for differentiated thyroid carcinoma.
METHODSAn extended collar incision was used for neck dissection in 82 consecutive patients with thyroid carcinoma from May 1999 to December 2006. The incision was designed to start as a conventional thyroid collar incision, and then to extend it along the skin crease to the anterior border of trapezium, so to avoid the vertical limb of conventional hockey stick incision. There were 60 females and 22 males in this series, with a median age of 40.5 years (range, 10 to 80 years). Ninety-six procedures of neck dissection were performed in 82 patients, including one radical neck dissection, one type I modified neck dissection, 8 type II modified neck dissections, and 86 type III modified neck dissections.
RESULTSThe average time of anesthesia was 197 minutes. The average dissected lymph nodes were 37.5, with average metastasis in 8.8 nodes. Eight patients (9.8%) developed complications related to neck dissection. The follow-up period in these patients were 1 to 96 months with a median follow-up time of 23 months. Cervical recurrence was found in only one patient (1.2%). Neither death nor distant metastasis was observed in this series.
CONCLUSIONIt is feasible to perform a modified neck dissection for differentiated thyroid cancer through the extended collar incision. The preliminary results show that the above described incision is not only oncologically safe, but also offers a cosmetic benefit for the patient with thyroid carcinoma.

OBJECTIVETo investigate the effect of recurrent laryngeal nerve (RLN) identification on the complications after total thyroidectomy and lobectomy.
METHODSTotal 134 consecutive patients undergoing total thyroidectomy or thyroid lobectomy from January 2003 to November 2004 were investigated retrospectively. Patients were divided into two groups: RLN identified (Group A) or not (Group B). The two groups were compared for RLN injury and hypocalcaemia.
RESULTSThe numbers of patients and nerves at risk were 71 and 129 in Group A, and 63 and 121 in Group B, respectively. RLN injury in Group A (0) was significantly lower than that in Group B (5 [7.9%]) patients, 7 [5.8%] nerves) for the numbers of patients (P=0.016) and nerves at risk (P=0.006). Temporary hypocalcaemia was significantly higher in Group A than in Group B (14 [24.1%] vs 6 [10.3%], P=0.049). Permanent complications in Group B were significantly higher than those in Group A (13 [20.6%] vs 4 [5.6%], P=0.009).
CONCLUSIONRLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy.

BACKGROUND/AIMS: Endoscopic resection (ER) of superficial esophageal neoplasm (SEN) is a technically difficult procedure. We investigated the clinical outcomes of ER for SEN to determine its feasibility and effectiveness. METHODS: Subjects who underwent ER for SEN at Asan Medical Center between December 1996 and December 2010 were eligible. The clinical features of patients and tumors, histopathological characteristics, adverse events, ER results and survival were investigated. RESULTS: A total of 129 patients underwent ER for 147 SENs. En bloc resection (EnR) was performed in 118 lesions (80.3%). Complete resection (CR) was accomplished in 128 lesions (86.5%), and curative resection (CuR) was performed in 118 lesions (79.7%). The EnR, CR, and CuR rates were significantly greater in the endoscopic submucosal dissection group when compared to those in the endoscopic resection group. Adverse events occurred in 22 patients (17.1%), including bleeding (n=2, 1.6%), perforation (n=12, 9.3%), and stricture (n=8, 6.2%). Local tumor recurrence occurred in 2.0% of patients during a median follow-up of 34.8 months. The 5-year overall and disease-specific survival rates were 94.0% and 97.5%, respectively. CONCLUSIONS: ER is a feasible and effective method for the treatment of SEN as indicated by favorable clinical outcomes.

OBJECTIVETo investigate the clinical characteristics and prognosis of second primary tumor of tongue (SPTr) after nasopharyngeal carcinoma (NPCR) treated with radiotherapy.
METHODSClinical data of 53 patients with SP7T after NPCR (group A) and 252 patients with primary tongue carcinoma (group B) were analyzed retrospectively with regard to clinical characteristics and survival rate (Kaplan-Meier); and multivariate analysis was performed using Cox proportional hazards model.
RESULTSThere was no significant difference between group A and group B ( P > 0. 05) in the presenting age, sex, tumor size, cTNM stage, tumor differentiation and the rate of distant metastasis. The overall 5-year survival rates were 41.6% in group A and 56.3% in group B (chi2 = 4.40, P = 0.0359) with a statistically significant difference between two groups. The differences of tumor location (chi2 = 61.18, P = 0.000) and rate of clinical (cN+, chi2 = 6.846, P = 0.009) or pathological lymph node metastasis (pN+, X2 = 3.993, P = 0.046) were also statistically significant between group A and group B, respectively. Multivariate analysis showed that age at presence, cTNM stage and with or without neck lymph node dissection were independent risk factors affecting survival.
CONCLUSIONSecond primary tongue carcinoma after radiotherapy for nasopharyngeal carcinoma is likely to occur on the dorsal aspect of the tongue with worse prognosis but with a lower rate of lymph node metastasis than that of primary tongue carcinoma. However, radiotherapy history is not an independent influencing factor on prognosis. Surgical resection or combined modality therapy may give a better prognosis.

OBJECTIVETo summarize the experience in diagnosis and surgical treatment of parathyroid adenoma and carcinoma (PTA and PTC) in our department.
METHODSThe clinical and pathological data of 48 cases admitted in our department from Jan 1995 to Dec 2005 were reviewed. Among the 48 cases, 46 cases were of parathyroid adenoma and 2 cases of parathyroid carcinoma. The average clinical history of the 48 cases was 3.65 +/- 2.83 years. The serum calcium and PTH levels were elevated in all the 48 cases. In 31 cases ultrasonographic results were consisted with that of 99mTc-MIBI scintigraphy. Unilateral neck exploration was performed in 18 cases and no case with post-operative tumor remnants was found. In other 13 cases bilateral exploration was performed but no one case was found to be tumor positive in the opposite side of the glands. Tumors resection was performed in all the 48 cases, among which in the 2 cases with PTC, ipsilateral thyroid lobe excision and modified neck dissection were also performed.
RESULTSClinical symptoms of all the patients were relieved after operation. No recurrent case was found during the follow-up periods (from 1 month to 10 years). The average level of serum calcium and PTH declined significantly after operation. The post-operational serum calcium and PTH levels at 3 days after operation were even lower than normal. Transient post-operational hypocalcemia was found in almost all the patients. The serum calcium and PTH levels in all patients recovered to normal level within a periods from 1 week to 3 months after operation. The sensitivity and positive prediction value of localization methods were 97.0% and 94.1% of ultrasonography, respectively, and 100% and 97.3% of 99mTc-MIBI scintigraphy, respectively.
CONCLUSIONPatients with chronic bone diseases, repeatedly recurrent nephrolithiasis, peptic ulcer disease or pancreatitis should be regarded as suspicious cases of PTA and PTC, and serum calcium assay should be performed as a routine screening procedure. Serum calcium and PTH assays are both reliable methods for the diagnosis of PTA and PTC. A combination of ultrasonography and 99mTc-MIBI scintigraphy is sufficient for locating adenomas. Accompanied by intraoperative pathological examination, unilateral neck exploration is an acceptable approach for patients with definitely preoperative confirmed adenoma localization.
