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 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.

ObjectiveTo investigate the indications and clinical effect of pancreatoduodenectomy with extended lymphadenectomy for pancreatic head carcinoma. MethodsThe clinical data of 21 patients with pancreatic head carcinoma that performed pancreatoduodenectomy with extended lymphadenectomy between June 2010 to June 2011 in Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology were retrospective analyzed. The 21 patients included 15 men and 6 women with an age range of 36-57 years and an average age of 47.8 years. ResultsThere were 3 cases(14.3%), 9 cases(42.9%), 8 cases(38.1%), and 1 case(4.8%) in stageⅠ, ⅡA, ⅡB, andⅢ, respectively. Eighteen cases had a R0 resection(85.7%) and 3 cases had a R1 resection. The total number of resected lymph nodes were 14-43 with an average of 27.4. Lymph node invasion occurred in 10 cases(47.6%). The average operative time was 6.8 h(5-8.5 h) and the average amount of blood transfusion was 5.6 U(3-8 U). There was no death in this group and 5 cases(23.8%) had postoperative complications. Tree cases(14.3%) developed pancreatic fistula, 1 case(4.8%) developed bile leakage, 1 case(4.8%) developed abdominal hemorrhage, 1 case(4.8%) developed gastrointestinal bleeding, and 2 cases(9.5%) developed intractable diarrhea. Postoperative pathological results in high, medium, and low differentiated adenocarcinoma was 6 cases(28.6%), 10 cases(47.6%), and 5 cases(23.8%), respec-tively. Twenty one cases were followed-up, the follow-up time ranged from 5 to 40 months with a median time of 19 months. 1-, 2-, and 3-year cumulative survival rates was 66.7%, 38.1%, and 19%, respectively. ConclusionSelective application of pancreatoduodenectomy with extended lymphadenectomy in resectable pancreatic head carcinoma is conducive to increase the proportion of the radical resection and improve the prognosis, but the postoperative complications is higher.
ObjectiveTo summarize the complications after supraclavicular lymph node dissection for invasive breast cancer patients with ipsilateral supraclavicular lymph node metastasis but without distant metastasis, and to analyze its safty. MethodsA retrospectively clinical analysis of the complications of 98 invasive breast cancer patients with ipsilateral supraclavicular lymph node metastasis but without distant metastasis, who underwent supraclavicular lymph node dissection in our hospital from Jan. 2014 to Dec. 2015 was performed. ResultsThere were 20 cases of lymphedema (20.4%, 20/98), 4 cases of hypaesthesia (4.1%, 4/98), and 4 cases of abduction restriction of shoulder joint (4.1%, 4/98). No other serious complications occurred. There was no shape change of shoulder and upper arm abduction, facial edema, head and neck disorders, pleural effusion or chylothorax happened. The extubation time of drainage tube at axillary and chest wall in 78 cases was in 1 month after the operation, 18 cases was in 1-2 months, and 2 cases was in 2-3 months. There were 14 cases (14.3%) suffered from the ipsilateral axillary or pleural effusion after extubation. The extubation time of supraclavicular drainage tube in 98 cases was 3-7 days after the surgery, with the median of 4.5 days, including 3 cases (3.1%) of chyle leakage. ConclusionThe supraclavicular lymph node dissection has no serious postoperative complications, and is safe to patients with ipsilateral supraclavicular lymph node metastasis but without distant metastasis.
Objective To investigate and evaluate prevention and treatment of seroma by transposition of tissue flaps and Arista hemostatic powder after regional lymph node resection in patients with malignant tumors. Methods Twelve patients (6 males, 6 females; aged 31-81 years, with metastatic tumors underwent prevention and treatment of seroma with the tissue flaps and Arista hemostatic powder spray after regional lymph node resection. The metastatic tumors involved the axilla in 1 patient with breast carcinoma, the iliac and inguinal regions in 2 patients with carcinomas of theuterine cervix and the rectum, and the inguinal region in 9 patients, including4 patients with malignant fibrous histiocytoma（3 in the thigh, 1 in the leg）,2 patients with squamous carcinomas in the leg, 1 patient with synovial sarcomain the knee, 1 patient with epithelioid sarcoma in the leg, and 1 patient with malignant melanoma in the foot. As for the lymph node removal therapy. 1 patientunderwent axillary lymph node removal, 2 palients underwent lymph node removal in theiliac and inguinal regions, and 9 patients underwent lymph node removal inthe inguinal region. Meanwhile, of the 12 patients, 6 patients underwent transpostion of sartourius flaps with Arista hemostatic powder, 3 patients underwent transposition of the rectus abdominis myocutaneous flaps (including 2 patients treatedwith Arista spray befor the wound closure and 1 patient treated by transposition of local skin flaps with Arista spray used again),and 3 patients underwent only the suturing of the wounds combined with Arista. At the same time, of the 12 patients,only 4 patient underwent the transplantation of artificial blood vessels. Results The follow-up for 2-10 months after operation revealed that 10 patients, who had received the transposition of tissue flaps and the spray of Arista hemostatic powder, had the first intention of the incision heal with seroma cured. Nine patients were given a preventive use of Arista hemostaticpowder and therefore no seroma developed. The combined use of the transpositionof tissue flaps and Arista hemostatic powder spray achieved a success rate of 100% in the prevention or treatment of seroma. However, 1 patient developed microcirculation disturbance 24 hours after operation and underwent disarticulation of the hip; 1 patient developed pelvic cavity hydrops and died 10 months after operation. Conclusion The combined use of transposition of tissue flaps and Arista hemostatic powder spray can effectively prevent or treat seroma after regional lymph node removal in a patient with malignant tumor.
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 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.
