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 explore the safety, effectiveness and minimally invasive cosmetic evaluation results of treatment for papillary thyroid carcinoma (PTC) by video-assisted lateral neck dissection (VALND) or open lateral neck dissection (OLND).MethodsThe clinical data of patients with PTC who received surgical treatment in the Affiliated Hospital of Nanjing University Medical School from June 2015 to December 2019 were retrospectively analyzed. The data of 94 cases in the VALND group (n=47) and the OLND group (n=47) were finally included in this study, and perioperative conditions and minimally invasive cosmetic evaluation results between the two groups were studied.ResultsThere were no statistical differences of lateral metastatic lymph node numbers, operative time, postoperative drainage volume, drainage tube removal time and postoperative hospitalization days between the two groups (P>0.05). The lateral retrieved lymph node numbers, intraoperative blood loss, the degree of cervical paresthesia and the degree of cosmetic satisfaction in the VALND group were significantly better than those in the OLND group (P<0.05). There was no significant difference of surgical complications between the two groups (P>0.05).ConclusionWithout sacrificing surgical safety and effectiveness, VALND has better cosmetic effect and less neck trauma than OLND, which is worthy of clinical application and promotion.
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 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 investigate the perioperative efficacy and safety of all-port robotic lobectomy versus thoracoscopic lobectomy in stageⅠA non-small cell lung cancer. MethodsThe clinical data of patients with stageⅠA non-small cell lung cancer who underwent lobectomy with lymph node dissection performed by the same operator in our center from June 2019 to June 2022 were retrospectively analyzed. The patients were divided into a robotic group and a thoracoscopic group according to different procedures. We compared the relevant indexes such as operation time, intraoperative bleeding, number of lymph node dissection stations, number of lymph node dissection, postoperative tube time, postoperative hospitalization time, closed chest drainage volume, postoperative pain, postoperative complications and hospitalization cost between the two groups. ResultsThere were 83 patients in the robotic group, including 34 males and 49 females with a median age of 60.0 (53.0, 67.0) years, and 94 patients in the thoracoscopic group, including 36 males and 58 females with a median age of 60.5 (54.0, 65.3) years. There was no conversion to thoractomy or death in postoperative 90 days in both groups. No statistical difference was seen in the operation time, total postoperative drainage volume and postoperative complication rates between the two groups (P>0.05). Patients in the robotic group had less intraoperative bleeding (P<0.001), more lymph node dissection stations (P=0.002) and numbers (P=0.005), less postoperative pain (P=0.002), and shorter postoperative time with tubes (P=0.031) and hospital stay (P<0.001). However, the surgery was more expensive in the robotic group (P<0.001). ConclusionAll-port robotic surgery is safe and effective for patients with early-stage non-small cell lung cancer with less intraoperative bleeding, more lymph node dissection, less postoperative pain, and shorter hospital stay compared with the thoracoscopic surgery.
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.
ObjectiveTo systematically review the prognostic efficacy and safety of patients with ovarian cancer treated with systemic lymphadenectomy (SL). MethodsPubMed, The Cochrane Library, Web of Science, CNKI, WanFang Data, and CBM databases were electronically searched to collect randomized controlled trials (RCTs) and cohort studies on the prognostic outcomes of patients with ovarian cancer treated with SL from inception to December 16th, 2020. Six reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.4 software. ResultsA total of 5 RCTs and 23 cohort studies involving 6 166 patients were included. The results of meta-analysis showed that there were no significant differences in the 3-year survival rate, 5-year survival rate, 3-year progression-free survival rate, and 5-year progression-free survival rate between SL group and the no systemic lymphadenectomy (NSL) group. The results of the subgroup analysis showed that pelvic and para-aortic lymph node dissection combined with large omentum resection had a better prognosis for patients. ConclusionsCurrent evidence shows that SL has no significant efficacy on survival and progression-free survival in patients with ovarian cancer. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
ObjectiveTo investigate the cause and treatment for chyle fistula after neck radical dissection using harmonic scalpel. MethodsFrom January 2005 to April 2009, 105 patients with thyroid carcinoma underwent thyroidectomy by harmonic scalpel (harmonic scalpel group) and 110 patients with thyroid carcinoma by conventional procedures (conventional group). Postoperative chyle fistula in all the cases was studied retrospectively. ResultsThe incidence of chyle fistula was 5.71% (6 of 105 patients) in the harmonic scalpel group and 0.91% (1 of 110 patients) in the conventional group. The difference was significant between two groups (Plt;0.05). ConclusionsHarmonic scalpel increases the risk of chyle fistula in neck radical dissection. The conventional procedures with exposing and preserving or ligating the thoracic duct can reduce the risk significantly.
ObjectiveTo compare the differences of curative effect, cosmetic effect, and shoulder-neck function protection effect between video-assisted lateral neck dissection (VALND) and traditional open thyroid surgery (OTS) in the treatment of papillary thyroid carcinoma (PTC) with lateral cervical lymph node metastasis. MethodsFifty patients with unilateral PTC accompanied by ipsilateral cervical lymph node metastasis who underwent sternal incision approach VALND at Cancer Hospital Affiliated to Fudan University and Pudong Hospital Affiliated to Fudan University from January 2013 to December 2019 were collected. And 100 patients with unilateral PTC and ipsilateral cervical lymph node metastasis who underwent OTS during the same period were randomly selected at a ratio of 1∶2 using the random number method. All patients underwent unilateral thyroid lobectomy (or total thyroid lobectomy) + isthmus resection + central area (zone Ⅵ) and cervical lymph node dissection on the affected side (zones Ⅱ–Ⅴ). The therapeutic effect was compared between the two groups. ResultsCompare to OTS group, the operation time of VALND group was longer ［(218.3±86.6) min vs. (185.7±42.8) min, P=0.002］, but the hospital stay was shortened ［(6.1±2.2) d vs. (7.3±1.6) d, P<0.001］. In terms of surgical efficacy, there were no statistically significant differences between VALND group and OTS group in the number of lymph node dissections, the number of lymph node metastases, and the postoperative tumor recurrence rate (P>0.05). As for surgical safety, the two groups had similar rates of postoperative complications including recurrent laryngeal nerve injury, hypoparathyroidism, postoperative hematoma and infection(P>0.05). In terms of postoperative recovery, the scar color, vascular distribution, thickness, and softness, as well as in shoulder stiffness, tightness, pain, and numbness scores of VALND group were significantly lower than those in OTS group (P<0.05). ConclusionsFor PTC patients with lateral cervical lymph node metastasis, there is no significant difference in surgical efficacy and safety between VALND and OTS. However, VALND shows obvious advantages in reducing the length of cervical incisions, improving cosmetic effects, and protecting cervical and shoulder functions. Therefore, VALND through the sternal notch approach has certain promotion and application value in clinical practice.
