Effect of ultrasound-guided intercostobrachial nerve blockade in patients with post-mastectomy pain syndrome / 临床麻醉学杂志

Objective To investigate and evaluate the feasibility and analgesic effect of ultrasound guided intercostobrachial nerve (ICBN) blockade in patients with persistent pain after radical mastectomy with ICBN preservation.Methods In a total of 53 following-up female cases,aged 18-55 years,ASA Ⅰ or Ⅱ,receiving radical mastectomy with ICBN preservation during January,2014 to February,2016,19 patients complained persistent pain in the lateral chest,axilla and/or upper arm more than 3 months after the surgery were enrolled.ICBN blockade was performed using 0.5% ropivacine 10 mL injected in the potential space between the superior of pectoralis minor muscle and the inferior of serratus anterior muscle in the second intercostal space guided by ultrasound.Visual analogue scale (VAS) was applied to assess the pain intensity at rest,on movement,and with 100 kPa pressure before blockage and 30 min thereafter,and then the pain intensity (SPI) was calculated.All nerve blockade-related adverse events including local anesthetic-related allergy,central nervous system and cardiovascular toxicity were recorded.Seven-day follow-ups were required in all patients to assess the pain intensity.Results All 19 cases completed ICBN blockade guided by ultrasound,of which 17 cases completed the seven-day follow-ups.The mean difference in SPI was-9.19 VAS points (95%CI-11.24--7.14,P<0.01).Compared with each mean VAS and SPI before block,all that after block at day 1-6 were significantly decreased (P<0.01 or P<0.05).There were 14(82.4%),13(76.5%),7(41.2%) and 3(17.6%)cases that SPI was decreased over 5 points after block at day 1-4.No nerve blockade-related adverse event was observed.Conclusion Ultrasound guided ICBN blockade can relieve persistent post-mastectomy pain safely and effectively.

Effect of intercostobrachial nerve preserving in axillary lymph node dissection on sensory disturbance for breast cancer / 国际生物医学工程杂志

Objective To explore the effect of preserving intercostobrachial nerve (ICBN) in axillary lymph node dissection on sensory disturbance for breast cancer.Methods Clinical data of 146 cases of stage Ⅰ,Ⅱ and Ⅲa breast cancer patients treated by modified radical mastectomy was analyzed.The patients were randomly divided into two groups.Retention group included 67 patients who were performed axillary lymph node dissection preserving ICBN,and 79 cases undergoing axillary lymph node dissection were taken as control group.Data of the two groups were assessed to compare the operation time,nunber of lymph nodes dissection and sensory abnormalities of upper arms.Results In the follow-up of 1,3 and 6 months,the incidence rate of the lateral upper ann sensory disturbance were 17.9％ and 74.9％,11.9％ and 60.7％,7.4％ and 59.5％ respectively in the retention and control group,and the difference was statistically significant (x2=46.78,P＜0.001;x2=36.54,P＜0.001;x2=42.80,P＜0.001).Meanwhile,there was no obvious difference between the retention and control group in operation time and number of lymph nodes(P＞0.05).No local recurrence after operation occurred in the follow-up of 8 months to 5 years.Conclusions For stage Ⅰ,Ⅱ and Ⅲ a breast cancer patients undergoing axillary lymph node dissection,retaining ICBN can significantly reduce the chance of the postoperative medial upper arm sensory disturbance,improve the quality of life with no increase of local recurrence rate.

Lymph node dissection under the intercostobrachial nerve level in early breast cancer / 中华内分泌外科杂志

Objective To investigate the extent of axillary lymph node dissection which can not only ef-fectively evaluate the axillary status but also reduce the complications to the minimum in early stage breast can-cer. Methods 331 patients with early breast cancer surgically treated from Jan. 2011 to Dec. 2013 were retro-spectively analyzed. Their preoperative axillary state was evaluated. They undertook sentinel lymph node biopsy (SLNB) by pure methylene blue dye method and frozen section examination during surgery. According to the ex-tent of axillary lymph nodes dissection, patients were divided into SLNB group (98 cases) and intercostobrachial nerve level lymph node dissection (ILND) group (233 cases). The pros and cons of the operation were compared. Results The sentinel lymph nodes (SLN) labeled by methylene blue were located under the intercostobrachial nerve level. The average number of SLN and intercostobrachial nerve level lymph nodes were 5.64+1.68 and 13.34+3.61 respectively. The detection rate and the false negative rate of SLNB was 97.42% and 2.58% respec-tively. The medium follow-up was 27.5 months. There was no significant difference in postoperative complications including upper limb paresthesia, swelling or limitation of shoulder activity between the two groups. Conclusion ILND is an effective and suitable surgical method in early breast cancer patients with failed intraoperative SLN labeling or with one SLN metastasis.

Modified procedure and clinical value for preserving intercostobrachial nerve in breast cancer operation / 局解手术学杂志

Objective To study the method and clinical value of preservation of intercostobrachial nerve( ICBN) by fat dissolving meth-od during breast cancer operation. Methods The clinical data of 50 cases withⅠ~Ⅲa stage breast cancer from January 2013 to June 2013 were analyzed. Fifty patients were randomly divided into two groups,there were 26 patients in preservation group,whose ICBN were preserved by fat dissolving method during axillary lymph nodes dissection,and 24 patients in resection group,whose ICBN were not preserved by routine method during axillary lymph nodes dissection. Comparison of operation times,bleeding volume,the number of axillary lymph nodes dissection and upper arm sensory function of patients after operation between both groups was done. Results The mean time of operation was (102. 3 ± 15. 6) min in preservation group and(95. 6 ± 12. 4) min in resection group,while the number of axillary lymph nodes dissection was (19. 5 ± 8. 8 ) in preservation group and ( 19. 2 ± 9. 5 ) in resection group, with no significant difference between both groups (P>0. 05). Bleeding volume was (51. 2 ± 11. 5)mL in preservation group and (98. 5 ± 13. 4)mL in resection group,with significant differ-ences(P<0. 05). After postoperative one month,we observed upper arm sensory function of patients. It showed that 3 cases of sensory numb-ness or pain occurred in preservation group (11. 5%),20 cases of sensory abnormality occurred in resection group (83. 3%),mainly as sen-sory loss,numbness,pain or burning sensation,there was significant difference between both groups (P<0. 05). All patients were followed up half a year,patients with sensory abnormality in preservation group recovered,and recovery in resection group was not obvious,it still showed sensory abnormality in varying degrees. During the follow-up,no local recurrence or distant metastasis was found in both groups. Conclusion Preserving intercostobrachial nerve by fat dissolving method in breast cancer operation is based on conventional operation and made a few of improvements. It is simple and feasible. During the operation,we find that the axillary neurovascular is clearer,preservation of ICBN is easier. It does not affect the axillary lymph node dissection and operation time,while it can reduce incidence of postoperative sensory abnormality and improve the quality of life of patients,therefore it is worthy of clinical application.

Morbidade entre a pós-biópsia de linfonodo sentinela e a dissecção axilar no câncer de mama / Morbidity after sentinel node biopsy and axillary dissection in breast cancer

OBJETIVO: O objetivo deste estudo foi avaliar a morbidade cirúrgica pós-biópsia de linfonodo sentinela (BLS) ou dissecção axilar com (DA-NP) e sem preservação do nervo intercostobraquial (DA-NS). MÉTODOS: Fez-se estudo coorte prospectivo com 108 pacientes divididas em três grupos: BLS (n=35), DA-NP (n=36) e DA-NS (n=37). Foram avaliadas ocorrência de déficit sensorial, dor, linfedema, seroma e infecção no membro superior homolateral à cirurgia. Monofilamentos de Semmes-Weinstein foram usados para avaliar o déficit sensorial, perimetria braquial foi feita para avaliação da presença de linfedema e aplicado questionário de dor. Para análise estatística foram utilizados os testes ANOVA e Kruskal-Wallis. Foi feita análise bivariada e multivariada. RESULTADOS: Pelo menos uma complicação pós-cirúrgica, imediata ou tardia, ocorreu em 45/108 (41,7 por cento) pacientes avaliadas. A complicação mais comum foi dor. Houve diferença estatisticamente significante entre os três grupos somente quanto ao déficit sensorial (p=0,04). Dor, linfedema e déficit sensorial ocorreram com maior freqüência no grupo DA-NS. As pacientes dos grupos BLS e DA-NP não apresentaram diferenças estatisticamente significantes para nenhuma das variáveis analisadas. A pesquisa com os monofilamentos mostrou sensibilidade cutânea preservada em 28/35 pacientes do grupo BLS, em 25/36 pacientes do grupo DA-NP e em 10/37 pacientes do grupo DA-NS (p<0,001). CONCLUSÃO: A secção do nervo está relacionada a maior déficit sensorial havendo diferença estatisticamente significante entre os três grupos, o que não demonstrou ser significante com os demais critérios avaliados dentre os grupos analisados.

BACKGROUND: The aim of this study was to evaluate the morbidity after sentinel node biopsy (SNB) and axillary dissection with (AD-NS) or without sparing the intercostobrachial nerve (AD-NOS). Methods: A prospective cohort study was performed on 108 patients divided into three groups: SNB (n=35), AD-NS (n=36) and AD-NOS (n=37). We evaluated the incidence of sensory loss, pain, lymphedema, seroma formation and infection in the arm homolateral to the breast surgery. Semmes-Weinstein monofilaments were used to assess the sensory loss; brachial perimetry was used to evaluate presence of lymphedema and a pain questionnaire was administered. ANOVA and Kruskal-Wallis statistical tests were used. Bivariate and Multivariate analyses were performed. RESULTS: After surgery at least one complication was reported by 45/108 (41.7 percent) patients. Pain was the outcome more often reported by patients. In the three groups a significant difference was observed only regarding sensory loss (p=0.04). Pain, lymphedema, and sensory loss were more frequently found in the AD-NOS group. No significant difference was observed between SNB and AD-NS groups. Semmes-Weinstein monofilaments showed preservation of cutaneous sensitivity in 28/35 patients from the SNB group, in 25/36 patients from AD-NS group but in only 10/37 patients from AD-NOS group (p<0.001). CONCLUSION: The ICB section is associated with higher sensory loss, with statistically significant difference between the groups that were not shown to be significant with the others complications.
