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.
Objective To determine if laparoscopic assisted Ivor-Lewis cervical stapled esophagogastrostomy via a minor subaxillary incising enables better perioperative and medium-term outcome than Ivor-Lewis cervical stapled esophagogastrostomy via thorax for middle esophageal carcinoma without intumescent lymphnode of neck. Methods The perioperative and medium-term outcome of a series of 55 patients underwent Ivor-Lewis cervical stapled esophagogas-trostomy via thorax between April 2010 and December 2012 were as a historic cohort (group A, 36 males, 19 females at age of 65±8 years). And 46 patients underwent laparoscopic assisted Ivor-Lewis cervical stapled esophagogastrostomy via a minor subaxillary incising between January 2013 and March 2015 were as a prospective cohort (group B, 31males, 15 females at age of 66±7 years). Perioperative indexes, lymphadenectomy, and result at end of one year following up were compared. Results Compared with group A, there was shorter thoracic operation time (t=5.94, P < 0.05), shorter time of restored anus exhaust (t=2.08, P < 0.05), less pulmonary complication (χ2=3.08, P < 0.05) and less total perioperative complications (χ2=4.30, P < 0.05), shorter postoperative hospital stay (t=3.20, P < 0.05) in the group B. While no statistically significant difference was found between the two group in postoperative morbidity of circulation or digestive and associated with surgical techniques (all P>0.05), lymph node metastasis rate of cervico-thoracic (include cervical paraesophageal) or mediastinum or abdominal cavity (χ2=0.03, 0.15, 0.08, all P>0.05), lymph node ratio (LNR) of cervical thoracic (include cervical paraesophageal) or mediastinum or abdominal cavity (χ2=0.01,0.71, 0.01, all P>0.05), recurrence rate of tumour (χ2=0.04, P>0.05), or survival rate (χ2=0.13, P>0.05) one year after the surgery. Conclusion Laparoscopic assisted Ivor-Lewis cervical stapled esophagogastrostomy via a minor subaxillary incising is a more rational surgery of cervicothoracic and cervical paraesophageal lymph nodes dissection via intrathoracic instead of cervical approach for middle esophageal carcinoma.
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 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.
目的探讨胸中上段食管癌淋巴结清扫的合理范围。 方法回顾性分析2010年1月至2013年10月我院134例胸中上段食管癌淋巴结清扫患者的临床资料。将患者分为两组：三野组，56例，男50例、女6例，年龄（55.4±9.6）岁，行三野淋巴结清扫根治术；二野组，78例，男69例、女9例，年龄（56.3±7.3）岁，行完全二野淋巴结清扫根治术。比较两组临床效果。 结果三野组患者淋巴结转移率明显高于二野组（60.7%vs.42.3%，P < 0.05），主要差别在于三野组有较高的颈部淋巴结转移率（21.4%）。三野组与二野组患者上纵隔淋巴结转移率分别为33.9%和30.8%，差异无统计学意义（P>0.05）。三野组及二野组患者术后并发症发生率差异无统计学意义（P>0.05）。三野组及二野组患者术后１年生存率分别为96.3%和85.5%，差异有统计学意义（P < 0.05）；三野组及二野组患者术后1年内颈部淋巴结复发率分别为1.9%和11.8%，差异有统计学意义（P < 0.05）。 结论三野淋巴结清扫根治术有助于提高胸中上段食管癌手术根治性，能减少术后局部复发和转移，提高患者术后生存率，相对于完全二野淋巴结清扫术并不显著增加手术并发症。
Objective To explore the safety of minimally invasive esophagectomy (MIE) with three-field lymphadenectomy (3-FL) for esophageal squamous cell carcinoma (ESCC) by comparing the short-term outcomes between the 3-FL and the two-field lymphadenectomy (2-FL) in MIE. Methods The clinical data of patients with ESCC who underwent minimally invasive McKeown esophagectomy in our hospital from July 2015 to March 2022 were collected retrospectively. Patients were divided into a 3-FL group and a 2-FL group according to lymph node dissection method. And the clinical outcomes and postoperative complications were compared between the two groups. Results A total of 257 patients with ESCC were included in this study. There were 211 males and 46 females with an average age of 62.2±8.1 years. There were 109 patients in the 3-FL group and 148 patients in the 2-FL group. The operation time of the 3-FL group was about 20 minutes longer than that of the 2-FL group (P<0.001). There was no statistical difference between the two groups in the intraoperatve blood loss (P=0.376). More lymph nodes (P<0.001) and also more positive lymph nodes (P=0.003) were obtained in the 3-FL group than in the 2-FL group, and there was a statistical difference in the pathological N stage between the two groups (P<0.001). But there was no statistical difference in the incidence of anastomotic leak (P=0.667), chyle leak (P=0.421), recurrent laryngeal nerve injury (P=0.081), pulmonary complications (P=0.601), pneumonia (P=0.061), cardiac complications (P=0.383), overall complications (P=0.147) or Clavien-Dindo grading (P=0.152) between the two groups. Conclusion MIE 3-FL can improve the efficiency of lymph node dissection and the accuracy of tumor lymph node staging, but it does not increase the postoperative complications, which is worthy of clinical application.
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 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 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.
