To investigate the microsurgical management of cranionasal tumors and the method of the reconstruction of the skull base. Methods From June 2005 to October 2007, 20 patients with cranionasal tumor were treated. There were 10 males and 10 females, aged between 13 and 77 years (median 49 years). The disease course was 2 months to 13 years.The cranionasal tumors, proved by MRI and CT scans, located in the anterior skull base, paranasal sinus, nasal and/or orbit cavity. And their cl inical presentations were l isted as follows: dysosphresia in 14 patients, headache in 11 patients, nasal obstruction in 9 patients, epistaxis in 8 patients, visual disorder in 4 patients, exophthalmos in 4 patients and conscious disturbance in 2 patients. All 20 patients underwent transbasal surgery combined with transnasal surgery, and tumors were resected by one-stage operation. The skull base was reconstructed by surgical technique “Pull Down Sandwich” with pedicle periosteum flap. Results Tumors were resected by one-stage operation, and the anterior skull bases were reconstructed. Pathological examination showed 8 cases of mal ignant tumors and 12 cases of benign tumors. The total surgical excision was complete in 16 patients, and 4 patients with subtotal excision. There was no operative death. Eighteen patients were followed up 3 months to 2 years and 6 months. Transient cerebrospinal fluid rhinorrhea was found in 2 cases which were cured by lumbar drainage. And recurrence of tumor was observed in 5 patients 3 months to 2 years after operation. Conclusion Microsurgical operation via subfrontal approach assisted bytransnasal endoscopy is an effective method in management of cranionasal tumors, with the advantages of econstruction of the skull base with pedicle periosteum flap or “Pull Down Sandwich” and low compl ication rate.
ObjectiveTo explore and compare the therapeutic effects of neuro-endoscopic and craniotomic hematoma evacuation for hypertensive hematomas in the basal ganglia region. MethodsEighty-six patients with hypertensive hematomas in the basal ganglia regions treated between January 2010 and September 2014 were divided into neuro-endoscopy and craniotomy groups randomly with 43 in each. Hematoma was removed directly under neuro-endoscope in the endoscopic group, while it was removed under the operating microscope in the craniotomy group. The average operation bleeding amount, residual hematoma after operation, hematoma evacuation rate, the changes of National Institutes of Health Stroke Scale (NIHSS) and Barthel index (BI) scores before operation, 1 and 3 months after operation were compared between the two groups. All data were analyzed statistically. ResultsThe average amount of operation bleeding was (127±26) mL, postoperative residual hematoma was (6±4) mL, and the hematoma clearance rate was (86±9)% in the neuro-endoscopy group, while those three numbers in the craniotomy group were respectively (184±41) mL, (11±6) mL, and (72±8)%, with all significant differences (P < 0.05). The NIHSS and BI scores were not significantly different between the two groups before surgery (P > 0.05). Seven days, one month and three months after surgery, the NIHSS score was significantly lower, and the BI score was significantly higher in the neuro-endoscopy group than the craniotomy group (P < 0.05). ConclusionNeuro-endoscopic surgery for hypertensive hematomas in basal ganglia region is proved to have such advantages as mini-invasion, direct-vision, complete clearance and good neural function recovery after surgery, which is a new approach in this field.
Objective To explore the protection of the structure and function around the upper pole of the thyroid gland by endoscopic thyroidectomy combined with nerve detection through the gasless unilateral axillary approach. Methods From January 2019 to June 2020, 48 thyroid patients who underwent the gasless unilateral axillary approach combined with the endoscopy and nerve detection technology in the Department of Head and Neck Surgery of Zhejiang Provincial People’s Hospital were reviewed as the endoscopic group, and 53 thyroid patients underwent open surgery combined with the endoscopy and nerve detection technology as the open group. The protection of the functional structure of the suprathyroid pole were compared. Results In terms of operation time, the endoscopic group was longer than that of the open group (67.5 min vs. 54.1 min, P=0.001). There was no statistical difference between the two groups in terms of postoperative hospital stay and blood loss (P>0.05). Forty-seven patients with the endoscopic thyroid surgery through the gasless unilateral axillary approach effectively detected the superior laryngeal nerve (47/48, 97.9%), which was higher than that of the open group (40/53, 75.5%), P=0.003, and the exposure rate of hypoglossal nerve descending branch in the endoscopic group was also higher [31.3% (15/48) vs. 3.8% (2/53), P=0.001]. In the endoscopic group, the superior parathyroid gland was kept in situ during the operation, and there was no change of voice and cough after the operation. In the open group, there were 2 cases of autologous transplantation of the upper pole parathyroid gland, 2 patients had voice changes, and 1 case had partial upper pole banded muscle incision. There was no significant difference in the incidence of nerve injury complications, the rate of autologous transplantation of the upper pole parathyroid gland and the rate of anterior cervical banded muscle injury between the two groups (P>0.05). In addition, there was no significant difference in the levels of parathyroid hormone, blood calcium, blood magnesium and blood phosphorus between the two groups before/after operation (P>0.05). Conclusion During the endoscopic thyroidectomy through the gasless unilateral axillary approach, the nerve monitoring technology is combined with the exploration and protection of the superior laryngeal nerve on the surface of the medial cricothyroid muscle of the upper pole of the thyroid, and the fine capsule anatomy technology is used to protect the superior parathyroid gland in situ, which can more effectively expose the external branch of the superior laryngeal nerve. It is conducive to the protection of the structures around the upper pole.
【Abstract】Objective To evaluate the application of duct endoscopy in the diagnosis of breast diseases characterized by nipple discharge. Methods One hundred and sixtynine consecutive cases from October 2003 to September 2004 who had duct endoscopy for nipple discharge were reviewed and followed up. Results Of 169 cases, 79 ductitis, 62 intraductal papilloma, 9 intraductal carcinoma in situ, 19 without breast diseases were diagnosed under duct endoscopy. During following up, the diagnostic accuracy of intraductal papilloma and intraductal carcinoma in situ with duct endoscopy was 89.8%(44/49) and 55.6%(5/9),respectively. There was only one patient who had breast pain and mild skin redness which was cured with oral antibiotics for 3 days. Conclusion Duct endoscopy is an only technique to explore the etiology for duct discharge under vision. It is direct, safe and effective, with a high accuracy.
Objective To evaluate the cl inical results of posterior microendoscopic foraminotomy in the treament of cervical radiculopathy and cervical intervertebral disc protrusion. Methods From February 2004 to June 2007, 24 cases of cervical radiculopathy received posterior microendoscopic foraminotomy. There were 16 males and 8 females, aging 42-68 years (59 years on average), including 16 cases of cervical radiculopathy and 8 cases of cervical intervertebral disc protrusion.The course of disease was 6-15 months. The affected intervertebral discs were C4, 5 in 8 cases, C5, 6 in 12 cases, and C6, 7 in 4 cases. The radiological examinations showed that 8 protrusions included 6 soft tissue protusions and 2 rigid tissue protusions, and that cervical radiculopathy were caused by yellow l igament hypertrophy, Luschka’s joint hyperplasia, and abnormal position of facet joint. According to Japanese Orthopedic Association (JOA), the score before operation was (12.60 ± 1.52) points. Results The operation time was 90 to 120 minutes (100 minutes on average), the bleeding during operation was 100 to 150 mL (120 mL on average). Nerve root pain were rel ieved completely in 19 cases and were rel ieved partly in 4 cases. One case of calcified nucleus pulposus had neurological traction injury and recovered completely after 3 months. All cases were followed up 24-36 months (28 months on average). The radiological examinations after operation showed the intervertebral disc site was decompressed completely and the height of intervertebral disc and the cervical segmental al ignment were normal. At 24 months postoperatively, the JOA score was (16.10 ± 0.29) points, showing significant difference when compared with that of preoperation (P lt; 0.01). Conclusion The posterior microendoscopic foraminotomy can get to the operation site with miniincision, decrease tissue damage during operation, and avoid narrow intervertebral space, so it has satisfactory cl inical results.
Objective To compare the clinical and radiological outcomes of unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) and minimally invasive tubular TLIF (MT-TLIF) in treatment of lumbar degenerative diseases. Methods A clinical data of 75 patients with lumbar degenerative diseases, who met the selection criteria between August 2019 and August 2020, was retrospectively analyzed, including 35 patients in the UBE- TLIF group and 40 patients in the MT-TLIF group. There was no significant difference in general data such as gender, age, body mass index, disease type and duration, and surgical segment between the two groups (P>0.05), which was comparable. The operation time, intraoperative blood loss, hemoglobin (Hb) before operation and at 1 day after operation, the length of hospital stay, incidence of complications, and visual analogue scale (VAS) score of low back and leg pain, Oswestry Disability Index (ODI), Short-Form 36 Health Survey Scale (SF-36 scale), intervertebral disc height (IDH), sagittal Cobb angle, lumbar lordosis (LL), and the intervertebral fusion were compared between the two groups. Results Compared with MT-TLIF group, UBE-TLIF group had significantly longer operation time but less intraoperative blood loss and shorter length of hospital stay (P<0.05). The Hb levels in both groups decreased at 1 day after operation, but there was no significant difference in the difference before and after operation between the two groups (P>0.05). All patients were followed up, and the follow-up time was (14.7±2.5) months in the UBE-TLIF group and (15.0±3.4) months in the MT-TLIF group, with no significant difference (t=0.406, P=0.686). In both groups, the VAS score of low back pain, VAS score of leg pain, SF-36 scale, and ODI after operation significantly improved when compared with those before operation (P<0.05). There was no significant difference between 1 month after operation and last follow-up (P>0.05). There was no significant difference in the VAS score of low back pain, VAS score of leg pain, and SF-36 scale between the two groups before and after operation (P>0.05). At 1 month after operation, the ODI in the UBE-TLIF group was significantly better than that in the MT-TLIF group (P<0.05). At 1 month after operation, IDH, Cobb angle, and LL in both groups recovered when compared with those before operation (P<0.05), and were maintained until last follow-up (P>0.05). There was no significant difference in the IDH, Cobb angle, and LL between the two groups at each time point (P>0.05). Thirty-three cases (89.2%) in the UBE-TLIF group and 35 cases (87.5%) in the MT-TLIF group achieved fusion, and the difference was not significant (χ2=0.015, P=0.901). In the UBE-TLIF group, 1 case of intraoperative dural tear and 1 case of postoperative epidural hematoma occurred, with an incidence of 5.7%. In the MT-TLIF group, 1 case of intraoperative dural tear, 1 case of postoperative epidural hematoma, and 1 case of superficial infection of the surgical incision occurred, with an incidence of 7.5%. There was no significant difference in the incidence of complications between the two groups (χ2=1.234, P=1.000). Conclusion Compared with MT-TLIF, UBE-TILF can achieve similar interbody fusion in the treatment of lumbar degenerative diseases, and has the advantages of smaller incision, less bleeding, and shorter length of hospital stay.
ObjectiveTo explore the surgical technique and clinical effect of endoscopic assisted transaxillary breast tumor resection in the treatment of benign and malignant breast tumors. MethodsThe clinical data of 18 patients received endoscopic breast tumor resection from September 2020 to December 2021 in the Department of Breast Surgery, West China Hospital, Sichuan University, were retrospectively analyzed to evaluate the feasibility, tumor safety and postoperative cosmetic effect. There were 7 patients with benign breast tumors (a benign breast tumor group) and 11 patients with early breast cancer (a malignant breast tumor group). Breast-Q and Scar-Q questionnaires were used to evaluate postoperative quality of life and satisfaction of patients. ResultsEndoscopic breast tumor resection was performed successfully in 18 female patients, among whom 12 patients received day surgery. The mean age of benign and malignant breast tumor groups was 29.6±11.6 years and 46.7±14.3 years, the mean tumor size in pathological examination was 3.3±2.1 cm and 2.0±0.8 cm, and the operative time was 138.9±57.0 min and 177.3±46.3 min, respectively. One patient had positive resection margin and underwent intraoperative extended resection in the malignant breast tumor group. All the patients were successfully followed up, and the mean follow-up time of benign and malignant breast tumor groups was 6.8±4.0 months and 8.7±4.9 months, respectively. No complications or tumor recurrence occurred. The scores of psychosocial status, sexual well-being, chest wall status and breast satisfaction decreased one month after surgery and basically recovered to the preoperative level in one year, and the score of scar appearance increased to 64.6±5.9 points one year postoperatively. ConclusionEndoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.
Objective To investigate the effectiveness of unilateral biportal endoscopic discectomy (UBED), percutaneous endoscopic lumbar discectomy (PELD), and traditional fenestration discectomy (FD) in the treatment of lumbar disc herniation (LDH). Methods The clinical data of 347 LDH patients who met the selection criteria and underwent discectomy between January 2017 and December 2021 were retrospectively analyzed. They were divided into FD group (160 cases), PELD group (86 cases), and UBED group (101 cases) according to operation methods. There was no significant difference in gender, age, surgical level distribution, disease duration, and preoperative visual analogue scale (VAS) score and Oswestry disability index (ODI) between groups (P>0.05). The operation time, hospitalization stay, treatment cost, and incidence of surgery-related complications were recorded and compared between groups. The patients’ pain and functional recovery were evaluated by VAS score and ODI before and after operation. Results The operation time of FD group was significantly shorter than that of PELD group and UBED group, and the hospitalization stay was significantly longer than that of PELD group and UBED group (P<0.05); there was no significant difference between PELD group and UBED group (P>0.05). The treatment cost in UBED group was significantly higher than that in PELD group, and in PELD group than in FD group (P<0.05). All the patients were followed up 6-24 months, with an average of 14.6 months. VAS score of lower extremity and ODI in 3 groups significantly improved after operation when compared with that before operation (P<0.05). At 1 day after operation, VAS score of lower extremity of UBED group was significantly better than that in PELD group and FD group (P<0.05), but there was no significant difference between PELD group and FD group (P>0.05). There was no significant difference in VAS scores of lower extremity between the 3 groups at 1 and 3 months after operation (P>0.05). The difference of ODI before and after operation in FD group and UBED group was slightly better than that in PELD group (P<0.05), and there was no significant difference between FD group and UBED group (P>0.05). Incidence of surgery-related complications in FD group (20.0%) was significantly higher than that in PELD group (12.8%) and UBED group (6.9%), and PELD group was significantly higher than UBED group (P<0.05). All the incision infection occurred in FD group (12 cases), symptomatic disc cyst and myeloid hypertension-like occurred in 1 case each in PELD group.Conclusion UBED, PELD, and FD have similar effectiveness on lower extremity pain in early LDH. Compared with FD, UBED and PELD have the advantage of shorter hospitalization stay and fewer complications.
Objective To summarize the progress of percutaneous endoscopic lumbar interbody fusion in the treatment of lumbar degenerative diseases. Methods The relevant literature about percutaneous endoscopic lumbar interbody fusion at home and abroad in recent years was reviewed, the approaches, technical characteristics, short- and long-term effectiveness, and complications of different surgical procedures were summarized.
