Objective To introduce a new approach of neurotization to treatment of the shoulder syndrome after the radical neck dissection by using transpositional anastomosis of C7 posterior root and the spinal accessory nerve to reconstruct the function of trapezius muscle. Methods From March 1999 to February 2001, 10 patients underwent the neurotization during the radical neck dissection. In the operation, the apo-cranial part of spinal accessory nerve was preserved from the trapezius muscle (gt;3.0 cm in length) and anastomosed to C7 posterior root. Objective physical examinations and electromyography were conducted before and after operation.One, 6 and 12 months after operation the trapezius muscle function after the transpositional anastomosis was evaluated. Results One, 6 and 12 months after operation, the recovery rates of each part were as follows: 9.8%, 68.9% and 73.5% in upper part; 4.7%, 73.6% and 69.4% in middle part; and 6.2%, 70.5% and 70.3% in lower part. The range of abduction motion of upper arm in 7 cases (70%) exceeded 90°. The mean maximal abduction angle was more than 95°. Evaluation of the shoulder function showed that myoatrophy was mild and the disability of abduction was classified as grade Ⅱ in 7 cases and grade Ⅲ in 3 cases. Conclusion Transpositional anastomosis of the C7 posterior root to thespinal accessory nerve after radical neck dissection can well reconstruct the function of trapezius muscle. This approach provides a wide indication in comparison with the functional neck dissection without impairment of arm function afterthe cutting of C7.
ObjectiveTo study the significance, methods, and technique of group No.6 lymphadenectomy of the laparoscopic gastrectomy with D2 lymph node dissection for distal gastric cancer. MethodsThe relevant data of the 141 examples of group No.6 lymphadenectomy of the laparoscopic gastrectomy with D2 lymph node dissection for distal gastric cancer from Jan.1, 2008 to Dec.31, 2011 were retrospectively analysized. ResultsOne hundred and forty-one patients were successfully completed the group No.6 lymphadenectomy of laparoscopic distal gastrectomy with D2 lymph node dissection. With the number of cases of operation increasing, the operation time, bleeding volume, incidence rate of complication, and the number of operation transit cases stepped down year by year, and the number of the lymph node dissection stepped up (P < 0.000 1). No case died of the lymphadenectomy of the group No.6 lymph node. The medium vessels of colon, pancreas, and the gastroduodenal artery were the anatomic landmarks of the group No.6 lymphadenectomy. The space between the anterior lobe and the posterior lobe of transverse mesocolon and the prepancreatic space were the important surgical plane to carry out the group No.6 lymphadenectomy. ConclusionsOnly a team shall complete a certain amount of the operation, take the medium vessels of colon, pancreas, and the gastroduodenal artery as the anatomic landmark, accurately identify the space between the anterior lobe and the posterior lobe of transverse mesocolon, and the prepancreatic space, and take operation on the correct surgical plane, shall the group No.6 lymphadenectomy conform to the principle of the radical cure of the tumour and achieve the aim of the minimal invasion.
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.
OBJECTIVE To introduce a method to repair the vagina following pelvic exenteration for carcinoma of rectum in which the posterior wall of the vagina and cervix of the uterus were often involved. METHODS From 1990 to 1997 segment of the vascularized ileum was used to repair the vagina in 5 cases, and in 2 of which the whole vagina was repaired while in the other 3 cases only the posterior wall of the vagina was repaired. RESULTS All of the patients had successful results after operation repair. CONCLUSION Vascularized graft was an ideal material for the repair of vagina defect following pelvic exenteration for carcinoma of rectum, because this material was easily accessible, and its vascular pedicle was long enough for its transferring to the perineal region and the ileum had good blood supply which made healing easy. The vagina following repair had a thick posterior wall, good elasticity and very little scar tissue surrounded.
Objective To study the application of ultracision harmonic scalpel in laparoscopic radical gastrectomy. Methods Ten patients with gastric cancer were given laparoscopic-assisted radical gastrectomy by using ultracision harmonic scalpel. Results All operations were successfully performed with ultracision harmonic scalpel, and none of which converted into open surgery. The operation time was 300-492 min, mean (385±64) min. The blood loss was 100-500 ml, mean (401±70) ml. The number of harvested lymph nodes was 21-43, mean 31±6. The time for gastrointestinal function recovery was 3-6 d, mean (4.2±1.0) d. The time of patients’ taking out-of-bed activity was 3-７ d, mean (4.5±1.3) d. The time of taking liquid food was 4-６ d, mean (5.0±0.9) d. No case had relapse or metastasis after 4-20 months (mean 12.6 months) of follow-up. Conclusions Laparoscopic radical gastrectomy by using ultracision harmonic scalpel is safe and feasible. Ultracision harmonic scalpel has the advantage of minimal invasion, less bleeding and shorter operation time, which is a very important equipment and useful for laparoscopic gastrointestinal surgery.
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 explore the feasibility of breast cancer patients in China with 1–2 positive sentinel lymph nodes (SLN) to avoid axillary lymph node dissection (ALND). Methods A total of 328 patients who received sentinel lymph node biopsy (SLNB) in our hospital from 2010 to 2016 were collected retrospectively, and patients met the criteria of Z0011 clinical trials (which required no acceptance of neoadjuvant therapy, clinical tumor size was in T1/T2 stage, two or less positive SLNs were detected, received breast-conservation surgery, acceptance of whole breast radiotherapy after surgery and neoadjuvant systemic treatment) were enrolled to breast-conservation group. Patients met the criteria of Z0011 clinical trials, excepting the surgery (received non-breast-conservation surgery), were enrolled to non- breast-conservation group. Comparison of clinicopathological features between the breast-conservation group/non-breast-conservation group and the Z0011 ALND group was performed. Results Among the 328 patients, only 29 patients (8.8%) completely correspond with the results of Z0011 clinical trials. There was no statistical significance between the breast-conservation group and the Z0011 ALND group in the age, clinical T stage, expression of estrogen (ER), expression of progesterone (PR), pathological type, histological grade, number of positive lymph nodes, and incidence of non-sentinel node metastasis (P>0.05). A total of 81 patients were included in the non-breast-conservation group. It showed no statistical significance between the non-breast-conservation group and the Z0011 ALND group in expressions of ER and PR, and histological grade (P>0.05), while there was statistically significant difference in age, clinical T stage, pathological type,number of positive lymph nodes, and incidence of non-sentinel node metastasis (P<0.05). Patients in the non-breast-conservation group showed a lower age, higher percentage of lobular carcinoma and T2 stage, more positive lymph nodes, and high incidence of non-sentinel node metastasis. Conclusion It’s feasible for Z0011 clinical trials results to be used in the clinical practice of our country, but the actual situation of breast conservation in our country may lead to low adaptive population.
Objective To provide a current language for clinical and pathological discription of gastric cancer. Methods The literature in recent years on the distribution of lymph nodes and staging of gastric cancer were reviewed. Results The lymph nodes of gastric cancer are distributed near the blood vessel and organs of gastric milieu. To ensure radical gastrectomy rational and scientific, the anatomic structure of gastric milieu should be familiarized. Conclusion The excellent outcome of surgery will be achieved by the effective dissection and removel of lymph nodes in gastric cancer.
