Experienc of nurtitional treatment to 7 patients with acute renal failure (ARF) and nitrogemia after biliarty (tract) surgery is reported in this article. Nittrogen source inn all cases was obtained from "Renal Amine" and "7% Vamin" etc,which are composed of 8 essential amino acids (EAA), and the nergery sources are mainly supplyed by Intralipid (20 or 10%) and suitable amount of glucose. The nutritional admicture of "all in one" were employed as parenteral nutrition (PN). Satisfactary curative effecs in these patients were obtained. The suthors consider that (a) the nutritional treatment of different casuses of ARF should be providing enough energy and more EAA requirments than in normal need to synthesizw non-essential amino acide (NEAA) and protein from excessive blood urea nitrogen (BUN) for redcuing pritein breakdown and nitrogemia, and (b) 20% Intralipid is an effective low-volume, highly calories nutritional agent specially in ARF patients with restiction of waterr.
Objective To retrospectively analyze the effectiveness of percutaneous anterior odontoid and transarticular screw fixation for type II odontoid fracture treated in the elderly patients. Methods Between October 2009 and March 2012, 5 patients with odontoid fracture were treated with anterior triple screws fixation. There were 4 males and 1 female with an average age of 69.4 years (range, 65-74 years). Fracture was caused by falling injury from height in all cases. The average time between injury and operation was 6.8 days (range, 3-12 days). According to Anderson-D’Alonzo classification system, all 5 cases were classified as type II odontoid fractures; 1 case accompanied by anterior arch fracture. Four cases were rated as grade E and 1 case as grade D on the basis of Frankel classification system on nerve function evaluation. Percutaneous anterior odontoid and transarticular screw fixation were used in all cases. The operation time, intra-operative blood loss, X-ray exposure time, and complications were recorded. The X-ray films were taken to observe atlantoaxial stability and implant conditions. Results All patients were successfully complete the surgery, and no open operation was needed. The average operation time was 103.6 minutes (range, 93-114 minutes). The average intra-operative blood loss was 5.6 mL (range, 3-10 mL). The average X-ray exposure time was 24.2 seconds (range, 17-32 seconds). Good reduction of atlantoaxial joint and primary healing of incision were obtained in 5 patients. The average follow-up duration was 21.4 months (range, 12-35 months). Transient dysphagia occurred in 3 cases, and was cured after 5 days of expectant treatment. No major complications of carotid artery laceration, spinal cord injury, esophageal perforation, airway obstruction, and implant failure occurred. The X-ray films showed odontoid bony union, atlantoaxial stability and good position of screws. The average time of odontoid fracture union was 7 months (range, 5-10 months). Five patients had normal neurological function (Frankel grade E) at last follow-up. Three patients complained of neck discomfort and movement limitation and had normal daily activities without special therapy; the other 2 patients had no clinical symptom of discomfort. Conclusion Percutaneous anterior odontoid and transarticular screw fixation is a safe and effective procedure for treatment of type II odontoid fractures in the elderly patients with minimally invasive surgical advantages.
ObjectiveThe aim of this current meta-analysis is to evaluate the efficacy and safety of selective surgery after colonic stenting versus emergency surgery for acute obstructive colorectal cancer.MethodsThe studies published from January 1, 2000 to July 31, 2018 were searched from Pubmed, Embase, Cochrane Library, CNKI, Wanfang database, and VIP database. RevMan 5.3 software was used for data analysis.ResultsA total of 21 studies were included in this meta-analysis. Compared to emergency surgery, selective surgery after colonic stenting had significant lower mortality rate [OR=0.44, 95% CI was (0.26, 0.73), P<0.05], permanent stoma rate [OR=0.46, 95% CI was (0.23, 0.94), P<0.05], complication rate [OR=0.47, 95% CI was (0.35, 0.63), P<0.05], and wound infection rate [OR=0.40, 95% CI was (0.25, 0.65), P<0.05）], but had significant higher primary anastomosis rate [OR=3.30, 95% CI was (2.47, 4.41), P<0.05] and laparoscopic surgery rate [OR=12.55, 95% CI was (3.64, 43.25), P<0.05]. But there was no significant differences between the two groups as to anastomotic leak rate [OR=0.86, 95% CI was (0.48, 1.55), P>0.05].ConclusionsSelective surgery after colonic stenting can be identified in a reduced incidence of mortality rate, complication rate, permanent stoma rate, and wound infection rate, and also can increase primary anastomosis rate and laparoscopic surgery rate. Thus, for acute obstructive colorectal cancer, selective surgery after colonic stenting is better than emergency surgery.
Objective To explore the clinical effect of different types of free tissue transplantation on repairing tissue defects and reconstructing functions. Methods From November 2001 to September 2004, 14 types of freetissue transplantation and 78 free tissue flaps were applied to repairing tissue defects and reconstructing functions in extremities and maxillofacial region in 69 cases. Of the 69 cases, there were 53 males and 16 females (their ages ranged from 18 to 56, 31 on average). Five cases were repaired because of skin defects in foot, 22 cases were repaired because of skin defects in leg, 36 cases were repaired as the result of skin defects in hand or forearm and finger reconstruction, 3 cases were restored by virtue of ulna or radius defects, and 3 cases were repaired in maxillofacial region. There were 55 cases of open wound, in which 16 cases were infectious wound, 6 cases were osteomyelitis or pyogenic arthritis. There were 14 cases of noninfectious wound. The area of these tissue flaps ranged from 2.0 cm×1.5 cm to 43.0 cm×12.0 cm. The length of bone transplantation ranged from 10 cm to 15 cm. Results Arterial crisis occurred in 2 cases, venous crisis occurred in 2 cases.Seventysix flaps survived completely and 2 flaps survived partially which werelater healed. Fiftytwo cases were healed at stageⅠ, 13 cases were healed at stageⅡ(healing time ranged from 20 to 30 days), purulent infection occurred to 4cases(healing time ranged from 3 to 11 months). Bone healing time ranged from 6 to 8 weeks in finger reconstruction. Bone healing time ranged from 4 to 6 months in fibula transplantation. The function reconstruction and appearance were satisfying. The functions of all regions, where free tissues were supplied, were not disturbed. Conclusion Tissue transplantation and composite tissue transplantation are effective in repairing tissue defects and reconstructing functions.

Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. MethodsWe retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.
Objective To compare the predicted efficiency of macular hole closure index (MHCI) calculated by 2 different methods for postoperative anatomical outcomes after idiopathic macular hole (MH) surgery. Methods This is a prospective exploratory clinical study. A total of 63 patients (63 eyes) with idiopathic MH, who received vitrectomy, inner limiting membrane peeling and gas tamponade, were enrolled in this study. All the patients received optical coherence tomography (OCT) examination at each visit to measure the MHCI using the formula MHCI=（M+N）/BASE, M and N is the distance from outer limiting membrane break points to the beginning points of detached photoreceptor from retinal pigment epithelium of both side of the hole, respectively. BASE is the length of MH base. MHCI1 was measured by built-in caliper of OCT software, MHCI2 was measured by ImageJ software. The minimum macular diameter (MHD) was measured by built-in caliper of OCT software. Based on the OCT images, the anatomical outcomes were classified grade A (bridge-like shape closure), grade B (complete closure) and grade C (poor closure). Grade A and B are considered as good closure, grade C as poor closure. Patients were followed up at 3, 6 and 12 months after surgery. The closure grades at last visit were the final outcome. The relationship between MHCI1, MHCI2 and closure grades was analyzed. And the predicted efficiency of MHD, MHCI1 and MHCI2 for anatomical outcomes after the surgery was studied. Results The mean MHCI1 was 0.68±0.21 (0.30-1.35), MHCI2 was 0.95±0.26 (0.41-1.55), and MHD was (476.24±210.18) μm (127-956 μm). MHCI1 and MHCI2 were both negative correlated with the closure grades (r=?0.665, ?0.691; P＜0.001). The receiver operating characteristic (ROC) curve analysis of MHCI1, MHCI2 and MHD for the prediction of good or poor closure showed that area under the curve (AUC) was 0.928, 0.957 and 0.916 respectively, and 0.505, 0.67 and 559 μm were set as the lower cut-off value. The sensitivity was 96.2%, 92.3% and 90.9% respectively, and specificity was 81.8%, 72.7% and 76.9% respectively. Accordingly, the ROC curve analysis for the prediction of grade A or B closure showed that AUC was 0.840, 0.847 and 0.653 respectively, and 0.705, 0.965 and 364 μm were set as the upper cut-off value. The sensitivity was 80.0%, 82.9%, 63.4% respectively and specificity was 75.0%, 85.7%, 65.9%. Conclusion MHCI1 and MHCI2, measured by built-in caliper of OCT software or ImageJ software, both have good predictive efficiency for the anatomical outcomes of MH surgery.
Objective?To investigate the effectiveness of minimally invasive plate fixation in treatment of unstable pelvic fractures.?Methods?Between May 2006 and December 2009, 21 patients with unstable pelvic fractures were treated. There were 13 males and 8 females with an average age of 39 years (range, 21-66 years). The causes of injury included traffic accident in 9 cases, falling from height in 6 cases, and heavy pound injury in 6 cases. The time from injury to hospitalization was 1 to 4 hours with an average of 2.8 hours. According to Tile’s classification, there were 12 cases of type B and 9 cases of type C. After admission, bone traction and exo fixation were performed, and minimally invasive plate fixation was given at 5-24 days after injury.?Results?All incisions healed by first intention, and no complications of nerve and vessel injuries occurred. According to the reduction criteria of Matta radiography, anatomic reduction was achieved in 16 cases, satisfactory reduction in 4 cases, and fair reduction in 1 case. All patients were followed up 12 months. The X-ray films showed all fractures healed at 2-4 months (mean, 2.6 months). According to Majeed clinical evaluation, the results were excellent in 12 cases, good in 7 cases, and fair in 2 cases.?Conclusion?Minimally invasive plate fixation can provide effective fixation, reconstruct pelvic ring, and reduce perioperative complications in the treatment of unstable pelvic fractures.
ObjectiveTo evaluate clinical outcomes of single utility port video-assisted thoracoscopic surgery (VATS) lobectomy for patients with early-stage peripheral non-small cell lung cancer. MethodsWe retrospectively analyzed the clinical data of 46 consecutive patients with early-stage peripheral non-small cell lung cancer who underwent single utility port complete VATS lobectomy in the First Affiliated Hospital of Hebei north University from December 2012 through November 2014. There were 39 male patients and 7 female patients with their age of 42-76 (60.26±4.38) years (VATS group). There were 58 patients with early-stage peripheral non-small cell lung cancer who underwent lobectomy via traditional thoracotomy including 47 male and 11 female patients with their age of 44-73 (61.42±3.67) years for the same period (conventional thoracotomy group). Clinical outcomes were compared between the two groups. ResultsAll the operations were successful. There was no conversions during single utility port VATS lobectomy, and no periopera-tive death in both groups. The VATS group had significantly less blood loss (126.10±48.56 ml vs. 260.84±69.70 ml), and amount of thoracic drainage (230.52±50.22 ml vs. 380.16±96.24 ml, P<0.05). Hospital stay was significantly shorter in the VATS group than the conventional thoracotomy group (6.42±1.40 days vs. 9.64±2.08 days, P<0.05). However, there was no significant difference between the VATS group and the conventional thoracotomy group with regard to the opera-ting time (146.25±19.68 minutes vs. 139.26±25.39 minutes), number of lymph nodes procured (13.56±2.31 vs. 14.12±3.06), and postoperative complications (13.0% vs. 19.0%, P>0.05). ConclusionSingle utility port VATS lobectomy for patients with early-stage peripheral non-small cell lung cancer is technically feasible, with less blood loss and shorter hospital stays for achieving acceptable standards of lymph node dissection. It is a promising surgical procedures for patients with early-stage peripheral non-small cell lung cancer.
ObjectiveTo compare the effectiveness and changes of sagittal spino-pelvic parameters between minimally invasive transforaminal lumbar interbody fusion and conventional open posterior lumbar interbody fusion in treatment of the low-degree isthmic lumbar spondylolisthesis. MethodsBetween May 2012 and May 2013, 86 patients with single segmental isthmic lumbar spondylolisthesis (Meyerding degree Ⅰ or Ⅱ) were treated by minimally invasive transforaminal lumbar interbody fusion (minimally invasive group) in 39 cases, and by open posterior lumbar interbody fusion in 47 cases (open group). There was no significant difference in gender, age, disease duration, degree of lumbar spondylolisthesis, preoperative visual analogue scale (VAS) score, and Oswestry disability index (ODI) between 2 groups (P>0.05). The following sagittal spino-pelvic parameters were compared between 2 groups before and after operation: the percentage of slipping (PS), intervertebral height, angle of slip (AS), thoracolumbar junction (TLJ), thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), spino-sacral angle (SSA), sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI). Pearson correlation analysis of the changes between pre- and post-operation was done. ResultsPrimary healing of incision was obtained in all patients of 2 groups. The postoperative hospital stay of minimally invasive group [(5.1±1.6) days] was significantly shorter than that of open group [(7.2±2.1) days] (t=2.593, P=0.017). The patients were followed up 11-20 months (mean, 15 months). The reduction rate was 68.53%±20.52% in minimally invasive group, and was 64.21%±30.21% in open group, showing no significant difference (t=0.725, P=0.093). The back and leg pain VAS scores, and ODI at 3 months after operation were significantly reduced when compared with preoperative ones (P<0.05), but no significant difference was found between 2 groups (P>0.05). The postoperative other sagittal spino-pelvic parameters were significantly improved (P<0.05) except PI (P>0.05), but there was no significant difference between 2 groups (P>0.05). The correlation analysis showed that ODI value was related to the SVA, SSA, PT, and LL (P<0.05). ConclusionBoth minimally invasive transforaminal lumbar interbody fusion and conventional open posterior lumbar interbody fusion can significantly improve the sagittal spino-pelvic parameters in the treatment of low-degree isthmic lumbar spondylolisthesis. The reconstruction of SVA, SSA, PT, and LL are related to the quality of life.
