Objective To study the necessity and feasibility of No.12b lymph node dissection in D2 lymphadenectomy for advanced distal gastric cancer, and the relation between No.12b lymph node metastasis and clinicopathologic factors. Methods Clinical data of sixty cases of advanced distal gastric cancer receiving D2 or D2+ radical correction were collected retrospectively, both of which were all plus No.12b lymph node dissections. The relationships between No.12b lymph node metastasis and clinicopathologic factors were analyzed. Results No death attributed to operation or severe operative complications were found. There were 12 cases (20.00%) with No.12b lymph node metastasis. The rates of No.12b lymph node metastasis in Borrmann Ⅲ-Ⅳ types, N2-3 of lymph node metastasis and T3-4 of tumor infiltration were 31.25% (10/32), 30.30% (10/33) and 29.73% (11/37), which were significantly higher than those in Borrmann Ⅰ-Ⅱ types 〔7.14% （2/28）〕, N0-1 〔7.41% （2/27）〕 and T1-2 〔4.35% （1/23）〕 respectively (Plt;0.05). There was no relationship between tumor size and No.12b lymph node metastasis. Conclusions No.12b lymph node dissection is safe and feasible for advanced distal gastric cancer. Further perspective studies on No.12b lymph node dissection influence on prognosis in more cases are required.
ObjectiveTo assess the efficacy of lymphadenectomy in different regions for esophageal squamous cell carcinomas located differently according to the lymph node grouping by Chinese expert consensus. MethodsThe medical records of 1 061 patients (886 males and 175 females with a median age of 60 (54, 65) years with esophageal cancer from March 2011 to December 2017 in our hospital were retrospectively analyzed. According to the pathological report, the lymph nodes were regrouped according to the Chinese lymph nodes grouping standard of esophageal cancer. The metastasis rate of each group of lymph nodes, the 5-year survival rate of metastatic patients and efficacy index (EI) were calculated. ResultsThe upper thoracic esophageal cancer mainly metastasized to the lymph nodes of C201-203 groups. The middle and lower thoracic tumors mainly metastasized to the lymph nodes of C205-207 groups. The lower thoracic tumor had a higher rate of metastasis to the abdominal lymph nodes. According to the metastasis rate, the mediastinal lymph nodes were divided into three regions: an upper mediastinum (C201-204), a middle mediastinum (C205-206), and a lower mediastinum (C207-209). The EIs of lymph nodes of C201-203 and C205-207 groups were higher. For patients with C201-207 groups metastasis, the 5-year survival rates ranged from 13.39% to 21.60%. For patients with positive lymph nodes in each region, tumors at different primary locations had no statistical difference in long-term survival (P>0.05). Patients with lymph nodes of C205 group in the upper thoracic tumors had lower EI and those in the middle and lower thoracic tumors had higher EIs. ConclusionThe effect of lymph node dissection in each area varies with the location of the tumor. No matter where the tumor is, it is necessary to dissect the upper mediastinal lymph nodes, especially the lymph nodes adjacent to the left and right recurrent laryngeal nerves. Group C205 should be classified into the lower mediastinal lymph nodes.
ObjectiveTo investigate the adequate surgical procedures for well-differentiated thyroid cancer (WDTC) located in the isthmus.MethodsNineteen patients with WDTC located in the isthmus were identified with WDTC and managed by surgery in Department of General Surgery in Xuanwu Hospital of Capital University from Jun. 2013 to May. 2018.ResultsAmong the nineteen cases, fifteen patients had a solitary malignant nodule confined to the isthmus, four patients had malignant nodules located separately in the isthmus and unilateral lobe. One patient received extended isthmusectomy as well as relaryngeal and pretracheal lymphectomy; six patients received isthmusectomy with unilateral lobectomy and central compartment lymph node dissection of unilateral lobe; four patients received isthmusectomy with unilateral lobectomy and subtotal thyroidectomy on the other lobe as well as central compartment lymph node dissection of unilateral lobe; seven patients received total thyroidectomy or isthmusectomy with unilateral lobectomy and nearly total thyroidectomy on the other lobe, as well as central compartment lymph node dissection of both sides; one patient received total thyroidectomy and central compartment lymph node dissection of both sides, as well as lateral thyroid lymph node dissection of both sides. The median operative time was 126 minutes (67–313 minutes), the median intraoperative blood loss was 30 mL (10–85 mL), and the median hospital stay was 6 days (4–11 days). Hypocalcemia occurred in 12 patients. There were no complications of recurrent laryngeal nerve palsy or laryngeal nerve palsy occurred. All the nineteen patients were well followed. During the follow up period (14–69 months with median of 26 months), there were no complications of permanent hypoparathyroidism occurred, as well as the 5-year disease-specific survival rate and survival rate were both 100%.ConclusionsFor patients with well-differentiated thyroid cancer located in the isthmus with different diameters and sentinel node status, individualized surgical procedures should be adopted.
Objective To study the effects of partial axillary lymph node dissection (PALD) on prognosis and upper limb function in patients with breast cancer. Methods Ninety-eight breast cancer patients with stage Ⅰ and Ⅱ were randomly divided into two groups and different surgical procedures following modified mastectomy were performed: partial axillary lymph node (level Ⅰ and Ⅱ) dissection (PALD) group (n=48) and total axillary lymph node (levelⅠ, Ⅱ and Ⅲ) dissection (TALD) group (n=50). The longterm positive relapse rate and upper limb function between 2 groups were compared. Results During the follow-up of 5 to 10 years (average 4.5 years), there were 2 cases (4.2%) of local recurrence on chest wall and one case (2.1%) of recurrence in axillary lymph node and one case (2.1%) of recurrence in supraclavicular lymph node in PALD group, and 2 cases (4.0%) of local recurrence on chest wall and no axillary lymph node recurrence and one case (2.0%) of recurrence in supraclavicular lymph node happened in TALD group. There was no statistical difference between PALD group and TALD group (Pgt;0.05). The incidence of upper limb edema and dysfunction was 4.2% (2/48) in PALD group and 16.0%(8/50) in TALD group (P＜0.01). There was no significant statistical difference of 5year and 10year survival rate between PALD group and TALD group (89.6% vs. 88.0%， 79.2% vs. 78.0%，Pgt;0.05). Conclusion PALD may reduce upper limb dysfunction after operation in patients with stage Ⅰ and Ⅱ breast cancer, and does not increase prognostic risk.
ObjectiveTo investigate the value of central lymph node dissection in patients with cN0 papillary thyroid carcinoma. MethodThe clinical data of 128 patients with cN0 papillary thyroid carcinoma who had been performed central lymph node dissection during their hospitalization from December 2010 to July 2012 in Chinese PLA General Hospital were analyzed retrospectively. ResultsThe central neck lymph node metastasis rate was 35.94%(46/128) in 128 patients with cN0 papillary thyroid carcinoma, which in the patients with aged less than 45 years, with the tumor diameter larger than 1 cm, and with capsule or extrathyroidal invasion were significantly higher than those in the patients with aged larger than 45 years, with the tumor diameter less than 1 cm, and without capsule or extrathyroidal invasion (P < 0.05). After the operation, there were 22(17.19%) patients with temporary hypoparathyroidism as well as 3(2.34%) patients with temporary recurrent laryngeal nerve injury. However, no permanent recurrent laryngeal nerve injury and permanent hypoparathyroidism occurred. During the 14-32 months follow-up with an average 23.4 months, 2 cases of lateral neck lymph node metastases were observed. ConclusionAs an essential, effective, and safe operation to the patients with cN0 papillary thyroid carcinoma, central lymph node dissection should be performed by experienced hands.
ObjectiveTo evaluate the role of the treatment for chylous fistula after neck dissection with adhesive vacuum assisted washing and aspiration. MethodsFrom January 2004 to December 2010, 20 patients with chylous fistula after neck dissection treated with adhesive vacuum assisted washing and aspiration were reviewed. ResultsEighteen of 20 recovered in 10 to 12 days’ treatment without any complications. Drainage volume bagan to decrease noticeably in 5 days. Two patients needed reoperation and were discharged on day 15 and 17 respectively after operation. ConclusionThe treatment with adhesive vacuum assisted washing and aspiration is a safe and effective way for chylous fistula after neck dissection.
ObjectiveTo systemically evaluate safety and effectiveness of laparoscopy-assisted distal gastrectomy (LADG) and conventional open distal gastrostomy(CODG) with D2 lymph node dissection for Chinese patients with distal gastric cancer. MethodsLiterature were searched in PubMed database, the Cochrane Library, China science citation database (CSCD), Wanfang database, China science and technology journal database (CSTJ), China biomedical literature database (CBM), and China academic journal network publishing database (CAJD) to identify clinical random controlled trials, comparing safety and effectiveness of LADG and CODG with D2 lymph node dissection for Chinese patients with distal gastric cancer. The retrieval time was from the inception to Jun. 2013. Meta-analysis was performed by Review Manager 5.2 software. ResultsA total of 7 clinical random controlled trials including 548 patients were analyzed. Compared with CODG group, LADG group had less blood loss (MD=-94.02, 95% CI:-140.96--47.07), shorter postoperative hospital stay(MD=-3.66, 95% CI:-5.76--1.57), earlier postoperative ambulation time(MD=-1.95, 95% CI:-2.74--1.17), earlier postoperative exhaust time (MD=-1.67, 95% CI:-2.05--1.30), lower incidence of complications(OR=0.26, 95% CI:0.14-0.51), P<0.050. But the operation time was longer in LADG group (MD=35.01, 95% CI:10.41-59.61, P=0.005). There was no significant difference between LADG group and CODG group on number of lymph node which were dissected during the operation (MD=-0.24, 95% CI:-0.99-0.51, P=0.530). ConclusionThe short-term outcome and safety of LADG for Chinese patients with distal gastric cancer is superior to CODG, but LADG prolongs the operation time and its long-term outcome should be proved by further outcomes of clinical controlled trials.
Abstract： Objective To investigate the effect of singledirection lobectomy plus systematic lymphnode dissection for primary nonsmall cell lung cancer (NSCLC) in the early stage by videoassisted thoracic surgery (VATS). Methods We retrospectively analyzed the clinical data of 89 patients who received VATS lobectomy plus systematic lymphnode dissection for earlystage primary NSCLC in the Second People’s Hospital of Chengdu between June 2006 and December 2009. Based on the operative approach, the patients were divided into two groups: VATSminithoracotomy group and singledirection lobectomy VATS group. In the former group, there were 46 patients, including 36 males and 10 females, with an age of 58.76±14.78 years. For patients in this group, minithoracotomy was carried out assisted by VATS. In the latter group, there were 43 patients, including 37 males and 6 females, with an age of 61.34±12.56 years, and singledirection lobectomy VATS was performed for patients in this group. Moreover, 42 patients undergoing routine posterior lateral open thoracotomy were chosen to form the control group (thoracotomy group, included 37 males and 5 females with an age of 56.30±15.59 years). The clinical features, such as operative time, operative blood loss, the number of systematic dissected lymph nodes, postoperative drainage quantity, postoperative complications and visual analogue scale (VAS) of chest pain were retrospectively analyzed to evaluate the early outcomes. Results No operative death occurred in all three groups. There were significant differences among the three groups in the postoperative drainage time (P=0.024), postoperative drainage quantity (P=0.019), operative blood loss (P=0.009), early outofbed activity time (P=0.031), and the incidence of cardiopulmonary complications (P=0.048). Compared with the VATSminithoracotomy group, the singledirection lobectomy VATS group was significantly lower or shorter (Plt;0.05) in postoperative drainage quantity (208.33±50.39 ml vs. 245.98±45.32 ml), operative blood loss (78.79±24.23 ml vs. 112.63±64.32 ml), and the early outofbed activity time (2.31±0.27 d vs. 3.56±0.31 d). The rate of using Dolantin in the control group was significantly higher than the other two groups (P=0.046, 0.007). The change of VAS score among the three groups after operation was also statistically significant (F=5.796, P=0.002). A total of 109 patients (37 in the VATSminithoracotomy group, 37 in the singledirection lobectomy VATS group, and 35 in the control group) were followed up after operation with a period of 2 to 48 months. Twentytwo patients were lost in the followup. There were 10, 9, and 8 deaths during the followup in the three groups respectively, and the median survival time was 40 months, 37 months, and 37 months respectively. There was no significant difference among the three groups in survival time (P=0.848). Conclusion VATS, especially VATS assisted single direction lobectomy and systematic lymphnode dissection for primary NSCLC in the early stage has the same surgical efficacy as the traditional open thoracotomy, and is minimally invasive, which contributes to a quick recovery. Consequently, it is a reliable approach for lung cancer in the early stage.
