Objective To summarize the efficacy of percutaneous endoscopic transforaminal unilateral decompression for the treatment of lumbar spinal stenosis, and to investigate the incidence and possible reasons for lower extremity symptoms of non-surgical side after surgery. Methods The clinical data of 46 patients who underwent percutaneous endoscopic transforaminal unilateral decompression for lumbar lateral recess stenosis between February 2016 and March 2018 were retrospectively analysed. There were 22 males and 24 females with an average age of 56.9 years (range, 21-90 years). The disease duration was 6 months to 12 years (mean, 4.8 years). There were 37 cases of single-segment lumbar lateral recess stenosis and 9 cases of multi-segment stenosis. All patients underwent single-segment surgery, including 2 cases of L3, 4, 35 cases of L4, 5, and 9 cases of L5, S1. For patients with multi-segment lumbar lateral recess stenosis, the single segment consistent with radicular symptom was selected for surgery. The visual analogue scale (VAS) scores of low back pain and sciatica and Oswestry disability index (ODI) scores were recorded preoperatively and at last follow-up to evaluate the relief of symptoms. Postoperative symptoms on non-surgical side of lower extremity including new or aggravated radiation pain and numbness were recorded. The surgical effectiveness was evaluated according to modified MacNab score at last follow-up. Results All the 46 patients underwent successful operations without postoperative complications such as wound infection, permanent nerve root injury, and deep vein thrombosis. The patients were followed up 12-37 months (mean, 23.8 months). Four patients suffered from radioactive pain and numbness for the non-surgical side of lower extremities at 1-3 months postoperatively, and the symptoms were improved after conservative treatment without revision surgery. VAS scores of low back pain and sciatica and the ODI scores were significantly improved at last follow-up when compared with preoperative ones (P<0.01). According to the criteria of modified MacNab scores, 25 cases were excellent, 17 cases were good, 3 cases were fair, and 1 case was poor. The excellent and good rate was 91.3%. Conclusion Percutaneous endoscopic transforaminal unilateral decompression for lumbar spinal stenosis would be able to relieve pain effectively and achieve good results. Lower extremity symptoms of non-surgical side may be observed postoperatively. Although the symptoms can be relieved by conservative treatment, further investigation should be carried out for the long-term result of those cases.
Objective To summarize the experience of sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst under ultrasound guided percutaneous catheter drainage combined with endoscopic technique. Methods The clinical data of 30 patients with aged and high risk pancreatic pseudocyst treated from January 2009 to January 2012 in this hospital were analyzed retrospectively. Results Percutaneous tubes were successfully placed in 30 patients， cystic liquid was sufficiently drained， and the compression symptom of cyst was relieved immediately. After stable disease， 12 patients with communicating cysts were diagnosed by using endoscopic retrograde cholangiopancreatography. Pancreatic duct stents were inserted in 12 patients with communicating cysts for 60-90d （with an average 70d） after endoscopic sphincterectomy and endoscopic pancreatic sphincterectomy. Cysts disappeared in the other 18 cases receiving external drainage with external drainage tubes， the drainage time was 15-90 d with an average 30d. Neither recurrence nor complications were found in all the cases during 12-21 months （with an average 18 months） follow-up. Conclusion Interventional ultrasound combined with endoscopic technique sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst has superiorities in little trauma， fewer complications， and exact effect.
ObjectiveTo evaluate the safety and effect of balloon sinuplasty for the treatment of chronic sphenoid sinusitis.
MethodsFrom November 2011 to March 2013, 17 patients received balloon catheter dilation of sinus ostia. All the patients were followed up for 12 months postoperatively and the therapeutic effect was evaluated.
ResultsAt the end of the following-up, the clinical symptoms of all the patients got relieved. Through nasal endoscopic examination, we found that apertura sphenoidalis developed well in 15 cases, sinus mucosa edema in one case, sinus stenosis in one case, and no postoperative complications occurred. The mean visual analogue scale (VAS) scores were 5.21±1.51 preoperatively and 3.23±1.34, 3.35±1.41, 3.58±1.46 at 3, 6 and 12 months postoperatively. The mean sino-nasal outcome test-20 scores were 12.50±1.96 preoperatively and 7.30±1.79, 7.64±1.93, 7.77±2.02 at 3, 6, 12 months postoperatively. The mean Lund-Kennedy endoscopic mucosal morphology scores were 3.51±1.47 preoperatively and 1.77±1.11, 1.88±1.01, 2.00±0.97 at 3, 6, 12 months postoperatively. The mean CT scores were 1.57±1.06 preoperatively and 0.85±0.62 at 12 months postoperatively. Compared with the preoperative scores, the postoperative scores were significantly different.
ConclusionBalloon sinuplasty is worthy of clinical application for its advantages of good clinical effect and safety.
Objective To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). Methods The recent l iterature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. Results There were two techniques of minimally invasive approach for CSR at peresent: percutaneous puncture techniques and endoscopic techniques. The degenerate intervertebral disc was resected or nucleolysis by percutaneouspuncture technique if CSR was caused by mild or moderate intervertebral disc herniations. The cervical microendoscopicdiscectomy and foraminotomy was an effective minimally invasive approach which could provide a clear view. The endoscopy techniques were suitable to treat CSR caused by foraminal osteophytes, lateral disc herniations, local l igamentum flavum thickening and spondylotic foraminal stenosis. Conclusion The minimally invasive procedure has the advantages of simple handl ing, minimally invasive and low incidence of compl ications. But the scope of indications is relatively narrow at present.
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.
Gastric tumors are neoplastic lesions that occur in the stomach, posing a great threat to human health. Gastric cancer represents the malignant form of gastric tumors, and early detection and treatment are crucial for patient recovery. Endoscopic examination is the primary method for diagnosing gastric tumors. Deep learning techniques can automatically extract features from endoscopic images and analyze them, significantly improving the detection rate of gastric cancer and serving as an important tool for auxiliary diagnosis. This paper reviews relevant literature in recent years, presenting the application of deep learning methods in the classification, object detection, and segmentation of gastric tumor endoscopic images. In addition, this paper also summarizes several computer-aided diagnosis (CAD) systems and multimodal algorithms related to gastric tumors, highlights the issues with current deep learning methods, and provides an outlook on future research directions, aiming to promote the clinical application of deep learning methods in the endoscopic diagnosis of gastric tumors.
ObjectiveTo explore the feasibility and clinical efficacy of laparoscopic sentinel lymph node biopsy combined with endoscopic submucosal dissection(ESD) for patients with early gastric cancer(EGC).
MethodsThe clinical data of 26 cases who received ESD combined with laparoscopic sentinel lymph node biopsy for EGC between March 2009 to August 2013 in Affiliated Hospital of Jiangnan University were analyzed retrospectively. These patients first underwent laparoscopic sentinel lymph node(SLN) biopsy. If frozen sectioning examination suggested there was lymph node metastasis, laparoscopic D2 radical gastrectomy would be operated. However, the ESD would be operated if the frozen sectioning examination was negative.
ResultsThe total numbers of SLN were 95, and mean numbers of SLN were 3.7±1.4(range from 1 to 6). Two patients with positive SLN underwent laparoscopic-assisted distal gastrectomy and 24 patients with negative SLN underwent ESD. The disease free survival(DFS) and local recurrence rate after ESD for EGC was 91.7%(22/24) and 4.2%(1/24), respectively. And the total DFS for all patients was 96.2% (25/26).
ConclusionESD for EGC is a safe and feasible procedure, combined with laparoscopic sentinel lymph node biopsy conforms more to the concept of principle of radical operation.
Objective To analyze and explain how to treat 1 patient with post-ERCP hemobilia based on best clinical evidence. Methods We used EST and EPBD, ENBD, Hemobilia as key words to search MEDLINE （1978 ～ 2004） and CBMdisc（1978 ～ 2004） to find the best clinical evidence and evaluated the quality of evidence. Results According to the evidence, we found that endoscopic papillary balloon dilation （EPBD） or endoscopic nasobiliary drainage （ ENBD ） may be more effective and better tolerated in the treatment ofpost-ERCP hemobilia. Our patient did not receive sufficient medical treatment after hemobilia. He was not given a general assessment before surgery including liver function tests. As a result, the patient died of liver failure and its complications. Conclusions We should treat such patients promptly and efficiendy after hemobilia. We should also evaluate their general condition properly before the operation.
Objective To evaluate the clinical effectiveness of ERCP/S+LC and LC+LCBDE in cholecystolithiasis and choledocholithiasis. Methods A fully recursive literature search was conducted in MEDLINE, EMbase, Cochrane Central Register of Controlled Trials in any language. By using a defined search strategy, both the randomized controlled trials (RCTs) and controlled clinical trials on comparing ERCP/ S+LC with LC+LCBDE in cholecystolithiasis and choledocholithiasis were identified. Data were extracted and evaluated by two reviewers independently. The quality of the included trials was evaluated. Meta-analyses were conducted using the Cochrane Collaboration’s RevMan 5.0.2 software. Results Fourteen controlled clinical trials (1 544 patients) were included. The results of meta-analyses showed that: a) There were no significant difference in the stone clearance rate between the two groups (RR=0.96, 95%CI 0.92 to 1.01, P=0.14); b) There were no significant difference in the residual stone rate between the two groups (OR=1.05, 95%CI 0.65 to 1.72, P=0.83); c) There were no significant difference in the complications morbidity between the two groups (OR=1.12, 95%CI 0.85 to 1.55, P=0.48); d) There were no significant difference in the mortality during follow-up visit between the two groups (RD= 0.00, 95%CI –0.03 to 0.03, P=0.84); e) The length of hospital stay in the LC+LCBDE group was shorter than that of the ERCP/S+LC group with significant difference (WMD= 1.78, 95%CI 0.94 to 2.62, Plt;0.000 1); and f) The LC+LCBDE group was superior to the ERCP/S+LC group in the aspects of procedure time and total hospital charges. Conclusion Although there aren’t differences in the effectiveness and safety between the ERCP/S+LC group and the LC+LCBDE group, the latter is superior to the former in procedure time, length of hospital stay and total hospital charges. For the influencing factors of lower quality and astable statistical outcomes of the included studies, this conclusion has to be verified with more strictly designed large scale RCTs.
ObjectiveTo compare postoperatively clinical effect of endoscopic total thyroidectomy via breast approach versus traditional total thyroidectomy via neck in treatment of thyroid papillary carcinoma on postoperative function of parathyroid gland.
MethodsRetrospective study performed on 124 thyroid papillary carcinoma patients who were hospitalized between June 2014 and December 2015 in Department of General Surgery of The First Affiliated Hospital of General Hospital of PLA. All patients underwent total thyroidectomy plus central Ⅵ lymphadenectomy. Endoscopic total thyroidectomy via breast were applied on 48 patients and traditional total thyroidectomy via neck were applied on 76 patients. Serum intact parathyroid hormone (iPTH) and calcium on postoperative day 1 were monitored for all patients. Then comparison of the serum iPTH and calcium between the 2 groups was performed.
ResultsSerum iPTH and calcium for all 124 patients were within the normal range before surgery, and there was no significant difference between the endoscopic total thyroidectomy via breast group and traditional total thyroidectomy via neck group in the serum iPTH and calcium (P > 0.05). On 1 day after surgery, the level of iPTH in endoscopic total thyroidectomy via breast group was lower than that of traditional total thyroidectomy via neck group[(20.8±5.7) pg/mL vs. (28.3±4.9) pg/mL], and ratio of lower iPTH than normal of endoscopic total thyroidectomy via breast group was higher[43.8% (21/48) vs. 22.4% (17/76)], P < 0.05; but there was no significant difference in serum calcium between 2 groups[(2.1±0.3) mmol/L vs. (2.0±0.5) mmol/L], P > 0.05. In addition, the incidence of perioral, chiral and pedal numbness was higher in endoscopic total thyroidectomy via breast group than that of traditional total thyroidectomy via neck group[47.9% (23/48) vs. 27.6% (21/76)], P < 0.05.
ConclusionsComparably, endoscopic total thyroidectomy via breast approach is more prone to lowly postoperative serum iPTH and calcium. Patients are more prone to exhibit clinical symptom such as perioral numbness, chiral and pedal numbness.
