Objective To study the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) and early endoscopic management for acute biliary pancreatitis. Methods Ninety-one patients with acute biliary pancreatitis were divided into ERCP group (46 cases) and control group (45 cases) according to the therapy methods. All patients were given positive conventional treatment, the patients of the ERCP group accepted endoscopic therapy within 48 h after hospitalization. The curative effects of two groups were observed, and the related indexes, such as time of abdominal pain relief, temperature to normal, leukocytes to normal, liver function to normal, average time in hospital, and mortality were compared between two groups. Results Among 46 patients by ERCP diagnosis, there were 27 cases of common duct stone (CDS), 6 cases of cholecystolithiasis, 3 cases of great diverticulum at duodenal papilla side, 4 cases of suppurative cholangitis, 3 cases of stenosis in bile common duct inferior segment and 3 cases of no abnormality. Among 27 cases of CDS, 20 patients had endoscopic sphincterotomy (EST), 4 had duodenal papilla artifistulation, 20 had calculus removed by once basket and aerocyst, and 7 patients with suppurative cholangitis and great stone saccepted EST or macadam after stabilization. The cases of great diverticulum at duodenal papilla side and cases of stenosis in bile common duct inferior segment accepted EST, the cases of suppurative cholangitis accepted endoscopic nasobiliary drainage (ENBD), and all accepted ENBD. The time of abdominal pain relief, temperature to normal, leukocytes to normal, liver function to normal, and the average time in hospital in the ERCP group were significantly shorter than those in the control group (Plt;0.05). The blood amylase to normal time and mortality had no significant differences between two groups (Pgt;0.05). Conclusion The early endoscopic management for patients with acute biliary pancreatitis can clear etiology, reduce the time in hospital and be minimally invasive, safe, and effective.
ObjectiveTo compare the curative effects and complications between endoscope-assisted treatment and scalp coronal incision for zygomatic complex fractures. MethodFifty zygomatic complex fracture patients treated between January 2008 to May 2014 were randomly divided into trial group (n=30) treated through endoscope-assisted procedure and control group (n=20) treated through scalp coronal incision. In the trial group, functional reduction and fixation of the fractures under endoscope were performed, and the control group was treated with coronal incision and internal fixation of the fractures. After the operation, all the patients were evaluated on the effects and complications through physical examination and CT review. ResultsThe number of grade-Ⅰ, -Ⅱ and-Ⅲ curative effects were respectively 24 (80.0%), 5 (16.7%), and 1 (3.3%) in the trial group, while those numbers in the control group were respectively 16 (80.0%), 3 (15.0%), and 1 (5.0%). There was no significant difference in the curative effects between the two groups (P>0.05). There were no cases of complications in the trial group, but there were 4 cases (20.0%) of facial nerve injury, 5 cases (25.0%) of hair loss, 4 cases (20.0%) of temporal sag, and 5 cases (25.0%) of scalp hematoma in the control group. The complication rate in the control group was significantly higher than that in the trial group (P<0.05). ConclusionsWhile the curative effects between endoscope-assisted treatment and scalp coronal incision for zygomatic complex fractures are not significantly different, endoscope-assisted technology can reduce the complications of the operation, which is a minimally invasive surgery and can promote good aesthetic appearance.
Objective To study the effect of surgical treatment of carpal tunnel syndrome (CTS) by endoscope through a transparent combined with dilation conductor to cut the transverse carpal l igament. Methods Between April 2003 and April 2008, 56 patients with CTS were treated with endoscopic carpal tunnel release through a transparent combined with dilation conductor. There were 8 males and 48 females with an average age of 50 years (range, 38-65 years). CTS was caused bywrist injury in 5 cases, by forearm fracture in 12 cases, and by wrist strain in 39 cases. The locations were left hand in 14 cases and right hand in 42 cases with a disease duration range of 2-7 years (4 years on average). According to Hamada classification of CTS, 38 cases were classified as stage I, 12 cases as stage II, and 6 cases as stage III. Results All cases achieved the primary heal ing of incision. All patients were followed up 14-68 months (40 months on average). According to Kelly’ s evaluation, the results were excellent in 25 cases, good in 22 cases, fair in 4 cases, and poor in 5 cases with an excellent and good rate of 83.93%. The distal motor latency of median nerve was (4.48 ± 0.50) ms at 1 months, (4.06 ± 0.35) ms at 3 months, (3.79 ± 0.25) ms at 6 months, and (3.42 ± 0.24) ms at 12 months after operation, showing significant differences when compared with the preoperative one [(5.09 ± 0.61) ms, P lt; 0.05]. There were significant differences among different time points after operation (P lt; 0.05). Conclusion The method of endoscope through a transparent combined with dilation conductor to cut the transverse carpal l igament is a simple and effective surgical procedure for treament of CTS, which can precisely cut the transverse carpal l igament and completely release the pressure of carpal tunnel.
Objective To compare vein graft patency after endoscopic great saphenous vein harvesting (EVH) and conventional open saphenous veinharvesting (OVH) in coronary artery bypass grafting (CABG), and to identify risk factors for vein graft stenosis. Methods The great saphenous vein was harvested using an EVH method in 60 patients, 34 males and 26 females, who underwent CABG in the General Hospital of PLA between May 2006 and May 2009. The mean patient age was 66.6±9.2 years in the EVH group.The OVH group had 60 patients (40 males and 20 females with a mean age of 65.7±10.6 years), chosen to match the clinical characteristics of the EVH group. 64multislice computed tomography (64MSCT) was used to evaluate vein graft patency at six months and two years postoperatively. We also collected and analyzeddata on possible risk factors for vein graft stenosis. Results The harvesting time was longer in the EVH group than in the OVH group (52.5±13.3 minutes vs. 36.1±18.0 minutes, t=2.13, P＜0.05). The EVH group requireda greater number of repairs to veins than did the OVH group (2.2±13 vs. 0.9±0.6,t=2.60, P＜0.05). There were no statistically significant differences invein length, number of vein grafts, or vein graft flow between the two groups. There was also no significant difference in vein graft patency between the EVH and OVH groups at six months postoperatively (96.2% vs. 94.5%) or at two years postoperatively (90.2% vs. 91.5%). The average of vein graft blood flow was a riskfactor for vein graft stenosis(t=2.61, P=001). Conclusion The EVH vein graft had a good patency rate at six months and two years after the surgery.
ObjectiveTo explore the safety, effectiveness, and cosmetic advantage of endoscopic thyroidectomy for differentiated thyroid cancer in the cT1N0 stage. MethodsThe clinical data of 148 patients underwent thyroidectomy for the cT1N0 differentiated thyroid cancer in the First Affiliated Hospital of PLA General Hospital and the PLA General Hospital from September 2010 to September 2013 were analyzed retrospectively, including 36 patients by total endoscopic thyroidectomy (TET group), 41 patients by endoscopic-assisted thyroidectomy (EAT group), and 71 patients by open thyroidectomy (OT group). The intraoperative status, early complications, late complications, and cosmetic result were compared among these three groups. ResultsAll the procedures were accomplished successfully.①In the intraoperative status: The operation time of the TET group was significantly longer than that of the EAT group(P < 0.05)or OT group (P < 0.05), drainage on the first day after operation in the TET group was significantly more than that in the EAT(P < 0.05)or OT group (P < 0.05), the intraoperative bleeding of the TET group or EAT group was significantly less than that of the OT group (P < 0.05), there were no statistical significances in the total number of lymph nodes dissection and number of positive lymph nodes among three groups (P > 0.05).②In the early complications: The postoperative pain score of the TET group was significantly lower than that of the EAT group (P < 0.05)or OT group (P < 0.05), there were no statistical significances in the postoperative bleeding, seroma, infection, transient recurrent laryngeal nerve paralysis, or transient hypoparathyroidism among three groups (P > 0.05).③In the late complications: there was no statistical significance in the perpetual recurrent laryngeal nerve paralysis, perpetual hypoparathyroidism, or thyroid cancer relapse among three groups (P > 0.05).④The best cosmetic result was obtained by the patients underwent TET as compared with the patients underwent EAT(P < 0.05)or OT (P < 0.05). ConclusionsEndoscopic procedure has the same effectiveness and safety with open procedure for differentiated thyroid cancer in the cT1N0 stage, but endoscopic procedure has a better cosmetic result than that open procedure. Compared with EAT, TET has more advantages in the cosmetic result.
ObjectiveTo analyze and explore the thyroid defunctionalization method for preoperative preparation of hyperthyroidism patients in endoscopic thyroid surgery. MethodsThe clinical data of 45 cases of hyperthyroidism treated with endoscopic surgery in this hospital from June 2009 to June 2014 were analyzed retrospectively. These patients were divided into study group (n=20) and control group (n=25) according to the preoperative preparation method, the study group was prepared with thyroid defunctionalization method, the control group was prepared with antithyroid drugs and iodine. The intraoperative blood loss, conversion to open surgery, and postoperative complications were compared in these two groups. ResultsThe intraoperative blood loss and the operation time of the study group were significantly less than those of the control group﹝intraoperative blood loss: (120.32±50.26) mL versus (200.63±60.95) mL, P < 0.05; operation time: (120.43±40.56) min versus (180.76±50.92) min, P < 0.05﹞. There was no case of conversion to open surgery in the study group, there were three cases of conversion to open surgery in the control group. The incidence of postoperative complications of the study group was significantly lower than that of the control group﹝10% (2/20) versus 24% (6/25), P < 0.05﹞. ConclusionThyroid defunctionalization method is more suitable as compared with the traditional method for the preoperative preparation of hyperthyroidism in endoscopic thyroid surgery.
ObjectiveTo evaluate the clinical experiences and treatment effectiveness of chronic venous insufficiency with venous ulcer in lower limb. MethodsSeventy-eight patients (88 limbs) suffering lower limb chronic venous insufficiency with venous ulcer from May 2004 to April 2011 in this hospital were analyzed retrospectively. All the patients had undergone high ligation for great saphenous vein plus endovenous laser treatment plus subfascial endoscopic perforator vein surgery (SEPS). ResultsPostoperative complications included 3 cases of subfascial haematoma; 2 cases of pneumohypoderma; 3 cases of numbness in anterior tibial and ankle areas. All the ulcers healed between 4 to 6 weeks. Follow up period was between 6 months to 5 years. There was only one recurrence due to residual varicose from ankle area. The mean operation time was 20 min (15－30 min) in SEPS, the average blood loss was 2 ml (1－5 ml), and the mean duration of postoperative hospitalization was 5 d (2－8 d). ConclusionsSEPS is a first treatment choice for CVI with venous ulcer. It has less invasiveness, lower chances for bleeding, shorter operation time, quicker recovery, and fewer complications.
Objective To evaluate the efficacy and safety of traditional Chinese medicine (TCM) in treating Chronic Rhinosinusitis (CRS) after Functional Endoscopic Sinus Surgery (FESS). Methods The following databases and periodicals such as PubMed (Jan. 1980 to Jan. 2009), MEDLINE (1980 to 2009), EBSCOhost (Jan. 1975 to Jan. 2009), CALIS (1984 to 2009), CNKI (1979 to 2007), VIP (1989 to 2009), CBM (1978 to 2009); Chinese Journal of Otorhinolaryngology Head and Neck Surgery (1990 to 2008), Journal of Clinical Otorhinolaryngology Head and Neck Surgery (1988 to 2008), Otorhinolaryngology Head and Neck Surgery (1990 to 2008), and Chinese Journal of Otorhinolaryngology of Integrated Traditional and Western Medicine (1996 to 2008) were searched by computer and handwork for randomized controlled trials (RCTs) about TCM to treat CRS after ESS. The trial screening, quality assessment, and the data extraction of the included trials were conducted before performing statistical analyses by using RevMan 4.2.10 software. Results A total of 32 RCTs in three sub-groups in Chinese literatures were identified with meta-analyses in comparisons of the cure rate (OR=1.99, 95%CI 1.78 to 2.23), total effective rate (OR=2.66, 95%CI 2.20 to 3.22), degree I postoperative improvement rate (OR=2.22, 95%CI 1.60 to 3.06), total postoperative improvement rate (OR=8.77, 95%CI 1.09 to 70.64), postoperative clean time (OR=2.54, 95%CI 1.70 to 3.79), postoperative epithelization time (OR= –29.46, 95%CI –37.73 to –21.18), and mucociliary transport rate (OR=1.14, 95%CI 0.22 to 2.06). A total of 4 RCTs were meta-analyzed to evaluate the safety in comparisons of gastrointestinal reaction (OR=0.25, 95%CI 0.00 to 33.78) and local reaction (OR=0.03, 95%CI 0.01 to 0.12). Conclusion The current evidence shows TCM in treating CRS after ESS tends to improve the clinical efficacy and reduce the cure time without obvious adverse reaction. Due to the low methodological quality of included trials, more RCTs with high quality and large scale are required.
The incidence, mortality, and disability rate of spontaneous intracerebral hemorrhage (SICH) are high, and its surgical and medical treatment is still controversial. With the development of micro-neurosurgical technology, minimally invasive surgery (MIS) has made great progress in the treatment of SICH. It can remove intracerebral hematoma in the early stage after SICH and minimize or eliminate secondary brain injury, which is of great significance to reducing the mortality and disability rate. For many years, due to its continuous progress, MIS has been more and more widely used in the treatment of SICH. This article mainly reviews the progress of MIS in SICH and related clinical research at home and abroad, and briefly describes several innovative techniques related to MIS, which aims to promote the exchange of clinical experience in MIS of SICH.
To evaluate the effectiveness of interrupt percutaneous endoscopy lumbar discectomy (PELD) through interlaminar approach for L5, S1 disc protrusion. Methods Between November 2006 and August 2010, 115 patients with L5, S1 disc protrusion were treated, including 79 males and 36 females with an average age of 38 years (range, 14-79 years). All patients showed the dominated symptom of the S1 nerve root. The working channel was establ ished by puncturing through interlaminar approach under the local anesthesia. After the needle was used to make sure no nerve root or dural sac on working face, the disc tissue was excised directly by bl ind sight. Then the nerve root decompression was observed through the endoscope. In patients with free type, fragment compression was observed through the endoscope, and the disc tissue around the nerve roots was removed, then the free disc tissue around intervertebral space was excised. Results One patient who failed to puncture changed to miniopen discectomy; 3 patients who failed changed to post lateral approach; and the others underwent interrupt PELD through interlaminar approach. Eighty patients were followed up 18 months on average (range, 12-36 months). The average Oswestry Disabil ity Index (ODI) was reduced to 13% ± 5% at 12 months after operation and to 12% ± 8% at last follow- up from 73% ± 12% at preoperation, showing significant differences (P lt; 0.01). According to modified Macnab ,s criterion, the results were excellent in 59 cases, good in 15 cases, fair in 3 cases, and poor in 3 cases at last follow-up, and the excellent and good rate was 92.5%. Conclusion For the treatment of disc protrusion at the L5, S1 level, interrupt PELD through interlaminar approach should be ideal with short operation time, small trauma, and quick recovery.
