ObjectiveTo investigate the effectiveness of endoscopic radical mastectomy for breast cancer combined with total pectoral muscle reconstruction with breast implants. Methods The clinical data of 138 female patients with breast cancer who met the selection criteria between April 2019 and December 2023 were retrospectively analyzed. The mean age of the patients was 43.8 years (range, 27-61 years). The maximum diameter of the tumors ranged from 1.00 to 7.10 cm, with an average of 2.70 cm. Pathological examination showed that 108 cases were positive for both estrogen receptor and progesterone receptor, and 40 cases were positive for human epidermal growth factor receptor 2. All patients underwent endoscopic radical mastectomy for breast cancer combined with total pectoral muscle reconstruction with breast implants. The operation time, intraoperative blood loss, prosthesis size, and occurences of nipple-areola complex (NAC) ischemia, flap ischemia, infection, and capsular contracture were recorded. The Breast-Q2.0 score was used to evaluate breast aesthetics, patient satisfaction, and quality of life (including the social mental health score, breast satisfaction score, and chest pain score). Patients were divided into two groups based on the time of operation after the technique was implemented: group A (within 1 year, 25 cases) and group B (after 1 year, 113 cases). The above outcome indicators were compared between the two groups. Furthermore, based on the postoperative follow-up duration, patients were classified into a short-term group (follow-up time was less than 1 year) and a long-term group (follow-up time was more than 1 year). The baseline data and postoperative Breast-Q2.0 scores were compared between the two groups. ResultsThe average operation time was 120.76 minutes, the average intraoperative blood loss was 23.77 mL, and the average prosthesis size was 218.37 mL. Postoperative NAC ischemia occurred in 21 cases (15.22%), flap ischemia in 30 cases (21.74%), infection in 23 cases (16.67%), capsular contracture in 33 cases (23.91%), and prosthesis removal in 2 cases (1.45%). The operation time of group A was significantly longer than that of group B (P<0.05), and there was no significant difference in intraoperative blood loss, prosthesis size, and related complications between the two groups (P>0.05). All patients were followed up 3-48 months (mean, 20 months). There were 33 cases in the short-term group and 105 cases in the long-term group. There was no significant difference in baseline data such as age, body mass index, number of menopause cases, number of neoadjuvant chemotherapy cases, number of axillary lymph node dissection cases, breast cup size, degree of breast ptosis, and postoperative radiotherapy constituent ratio between the two groups (P>0.05). At last follow-up, the breast satisfaction score in the patients’ Breast-Q2.0 score ranged from 33 to 100, with an average of 60.9; the social mental health score ranged from 38 to 100, with an average of 71.3; the chest pain score ranged from 20 to 80, with an average of 47.3. The social mental health score of the long-term group was significantly higher than that of the short-term group (P<0.05); there was no significant difference in breast satisfaction scores and chest pain scores between the two groups (P>0.05). No patient died during the follow-up, and 2 patients relapsed at 649 days and 689 days postoperatively, respectively. The recurrence-free survival rate was 98.62%. Conclusion Endoscopic radical mastectomy for breast cancer combined with total pectoral muscle reconstruction with breast implants has fewer complications and less damage, and the aesthetic effect of reconstructed breast is better.
ObjectiveTo analyze the value of indocyanine green (ICG) fluorescence imaging in the evaluation of blood flown of ipple-areola complex (NAC) and implant selection during single-port endoscopic breast reconstruction. Methods From November 2018 to March 2020, 19 patients who underwent single-port inflatable endoscopic nipple-sparing mastectomy combined with breast reconstruction in Beijing Friendship Hospital were retrospectively collected. ICG fluorescence imaging technology was used to evaluate the blood supply pattern and the risk of ischemic necrosis of NAC, so as to guide the selection of implant. At the same time, 14 patients who underwent single-port inflatable endoscopic nipple-sparing mastectomy combined with breast reconstruction in Beijing Friendship Hospital from February 2017 to October 2018 were selected as the historical control group (control group). NAC ischemic necrosis, breast satisfaction and implant removal were compared between the two groups. Results In the ICG group, there were3 cases of V1 pattern and 2 cases of NAC ischemic necrosis (1 case of grade 1, 1 case of grade 2). There was no NAC ischemic necrosis in 16 patients with V2 mode and V3 mode. No implant loss occurred in any of the patients. In the control group, 5 cases had NAC ischemic necrosis (all were severe ischemic necrosis), and 2 cases had implant loss. The rate of severe NAC ischemic necrosis in the ICG group was lower than that in the control group (P<0.01), but there was no significant difference in implant loss rate between the two groups (P=0.17). The breast satisfaction score of the ICG group was higher than that of the control group (P<0.01), but there were no significant difference in satisfaction scores of chestwell-being, psychological well-being and sexual well-being between the two groups (P>0.05). Conclusions ICG imaging can be used to evaluate the blood supply pattern during the operation of prosthetic body mass reconstruction, guide the choice of implant in immediate breast reconstruction, so as to further improve postoperative breast satisfaction.
ObjectiveTo evaluate the safety and clinical effect of laparoscopic Miles and perineal anal recon-struction operation for patients with low rectal cancer. MethodsOne hundred and two patients underwent Mile's and perineal anal reconstruction operation for rectal cancer in this hospital from April 2006 to February 2010 were analyzed retrospectively, in which 58 patients underwent laparoscopic surgery (laparoscope group) and 44 patients underwent open surgery (laparotomy group).All these data such as the survival time, operative time, intraoperative blood loss, harvested lymph nodes, the first anal exhaust time and liquid diet recovery time after operation, postoperative hospitalization, and postoperative complications were collected and compared between the laparoscope group and laparotomy group. ResultsThe demography and clinicopathologic characteristics were similar between these two groups (P > 0.05).The operation was successfully performed in all the patients.There was no death associated with the operation.Compared with the laparotomy group, the intraoperative blood loss was less (P < 0.05), the first anal exhaust time and liquid diet recovery time after operation, postoperative hospitalization were shorter (P < 0.05), the harvested lymph node was more (P < 0.05) in the laparoscope group.There were no significant differences in the operative time, postoperative complications, and the survival curves between the two groups (P > 0.05). ConclusionsThe clinical effects of laparoscopic and open Miles and perineal anal reconstruction operation are similar for patients with low rectal cancer.But laparoscopic operation is a safe, feasible choice with quicker recover after the operation.
ObjectiveTo observe the effect and significance of autologous fibrin clot on tendon-bone healing after anterior cruciate ligament (ACL) reconstruction.MethodsBetween October 2014 and January 2016, 34 patients (34 knees) with ACL injury were enrolled in the study. During ACL reconstruction, autologous fibrin clot was used in 17 cases (trial group) and was not used in 17 cases (control group). The anterior drawer test, Lachman test, and axial displa-cement test were positive in 2 groups before operation. There was no significant difference in gender, age, causes of injury, injury side, disease cause, and preoperative knee joint activity, Lysholm score, and American Hospital for Special Surgery (HSS) score between 2 groups (P>0.05), with comparable. The results of anterior drawer test, Lachman test, and axial displacement test were recorded and compared between 2 groups after operation. The knee joint activity, Lysholm score, and HSS score were used to evaluate the knee function recovery at 6, 24, and 48 weeks after operation; the graft signal intensity, graft signal to noise ratio, bone tunnel expansion, and graft tendon-bone node T2 value were measured.ResultsAll patients were followed up 48 weeks. Surgical incision healed at stage I. No joint infection and joint adhesion occurred. The drawer test, Lachman test, and axial shift test were negative in 2 groups. At 6, 24, and 48 weeks after operation, the Lysholm score of trial group was significantly higher than that of control group (P<0.05); there was no significant difference in knee joint activity between 2 groups (P>0.05). The HSS score of trial group was significantly higher than that of control group at 24 and 48 weeks (P<0.05), but no significant difference was found at 6 weeks (P>0.05). MRI measu-rement showed that there was significant difference in graft signal intensity, bone tunnel expansion, and graft signal to noise ratio between 2 groups at 6, 24, and 48 weeks after operation (P<0.05). There was no significant difference in graft tendon-bone node T2 value between 2 groups (P>0.05) at 48 weeks after operation, but difference was significant at 6 and 24 weeks (P<0.05).ConclusionAutologous fibrin clot can effectively enhance graft revascularization, and accelerate the process of tendon-bone healing after ACL reconstruction.
ObjectiveTo evaluate the effects of modified left ventricular reconstruction (LVR) and linear repair (LR) to post-infarct left ventricular aneurysm (LVA) and summarize the surgical experience of LVA. MethodsFrom May 2004 to December 2011, 47 patients were admitted in the Department of Cardiovascular Surgery, Renji Hospital Affiliated to Medical College of Shanghai Jiaotong University. There were 25 patients underwent LVR (group LVR, including 21 males and 4 females), 18 patients underwent LR (group LR, including 14 males and 4 females) and 4 patients underwent directly sutured (including 3 males and 1 female). Among them, 42 patients underwent coronary artery bypass grafting (CABG). During 6-24 months'follow-up, left ventricular ejection fraction (LVEF), quality of life and activity were measured. ResultsPostoperative LVEF was significantly higher than preoperative LVEF in group LVR(49.2%±13.6% vs. 32.5%±12.9%, P < 0.05) and group LR (47.5%±11.6% vs. 36.9%±11.6%, P < 0.05). One patient died in LR group (5.5%) and 1 died in LVR group (4.0%), no death occurred in directly sutured surgery. Total mortality was 4.2%. ConclusionLVR and LR are both effective treatment for LVA. Personalized treatment can receive satisfactory short-and long-term outcomes.
【Abstract】 Objective To investigate the feasibility of transpositional anastomosis of C4 anterior trunk and accessory nerve for functional reconstruction of the trapezius muscle so as to provide theoretical basis of repairing accessory nerve defects. Methods Thirty-six adult male Sprague-Dawley rats (weighing 200-250 g) were randomly divided into the experimental group (n=18) and control group (n=18). The transpositional anastomosis of C4 anterior trunk and accessory nerve was performed in the left sides of experimental group; the accessory nerve was transected in the left sides of control group; and the right sides of both groups were not treated as within-subject controls. The electrophysiological and histological changes of the trapezius muscle were measured. The values of the latencies and amplitudes of compound muscle action potential (CMAP) were recorded in the experimental group at 1, 2, and 3 months; the latency delaying rate, amplitude recovery rate, and restoration rate of muscular tension were caculated. The counts of myelinated nerve fibers from distal to the anastomotic site were analyzed. The transverse area of the trapezius muscle was also measured and analyzed in 2 groups. Meanwhile, the muscles and nerves were harvested for transmission electron microscope observation in the experimental group at 1 and 3 months. Results As time passed by, the experimental group showed increased amplitudes of CMAP, shortened latencies of CMAP, and improved muscular tension. At 3 months, the amplitude recovery rates were 63.61% ± 9.29% in upper trapezius muscle and 73.13% ± 11.85% in lower trapezius muscle; the latency delaying rates were 130.45% ± 37.27% and 112.62% ± 19.57%, respectively; and the restoration rate of muscular tension were 77.27% ± 13.64% and 82.47% ± 22.94%, respectively. The passing rate of myelinated nerve fibers was 82.55% ± 5.00%. With the recovery of innervation, the transverse area of the trapezius muscle increased, showing significant differences between experimental group and control group at different time points (P lt; 0.05). The transmission electron microscope showed that the myotome arranged in disorder at 1 month and tended to order at 3 months. Conclusion Transpositional anastomosis of C4 anterior trunk and the accessory nerve can effectively reconstruct the function of the trapezius muscle of rats.

Objective To explore the feasibility and short-term effectiveness of the modified radical resection and reconstruction in the treatment of malignant proximal humerus tumor. Methods The relevant anatomic data from 30 normal adult shoulder joint MRI were measured to analyze the feasibility of modified radical resection and reconstruction surgery in the treatment of malignant proximal humerus tumor. Five patients with malignant proximal humerus tumor were treated by using the modified radical resection and reconstruction surgery between March 2012 and January 2016. There were 1 male and 4 females, aged from 9 to 69 years (median, 46 years). There were 4 cases of osteosarcoma (Enneking IIA in 2 cases and Enneking IIB in 2 cases) and 1 case of metastatic carcinoma (moderately differentiated adenocarcinoma). The disease duration was 7 to 12 months (mean, 9 months). Recurrence of tumor was observed after operation, and the shoulder function was assessed according to Enneking skeletal muscle tumor function scoring system. Results Radiographic results showed that modified radical resection and reconstruction surgery was feasible, which was in allowable range of the maximum longitudinal diameter ( < 29.8 mm) and depth ( < 4 mm). The operation was successfully completed in all 5 cases, and pathological examination suggested that purposes of radical resection had achieved. All patients were followed up 3 to 49 months (mean, 15.6 months). One patient had local recurrence at 12 months after operation, and a shoulder joint amputation was performed; the other 4 patients had good prosthesis survival. At last follow-up, the function of the shoulder joint was obviously recovered when compared with preoperative function; Enneking's skeletal muscle tumor function score was 25.8 points (range, 24 to 27 points). Conclusion Modified radical resection and reconstruction surgery is feasible for the treatment of proximal humerus tumor, and it can maintain a good early shoulder function.
