Can failure of percutaneous drainage of postoperative abdominal abscesses be predicted?

BACKGROUND: Percutaneous drainage (PD) of complex postoperative abscesses associated with a variety of factors such as multiple location or enteric fistula remains a matter of debate. Accordingly, this retrospective study was designed to determine the predictive factors for failure of PD of postoperative abscess, in order to better select the patients who may benefit from PD. METHODS: From 1992 to 2000, the data of 73 patients who underwent computed tomography (CT)-guided PD for postoperative intra-abdominal abscess, were reviewed. PD was considered as failure when clinical sepsis persisted or subsequent surgery was needed. The possible association between failure of PD and 27 patient-, abscess-, surgical-, and drainage-related variables were assessed using univariate and multivariate analysis. RESULTS: Successful PD was achieved in 59 of 73 (81%) patients. The overall mortality was 3% but no patient died after salvage surgery. Multivariate analysis showed that only an abscess diameter of less than 5 cm (P = 0.042) and absence of antibiotic therapy (P = 0.01) were significant predictive variables for failure of PD. CONCLUSIONS: CT-guided PD associated with antibiotic therapy could be attempted as the initial treatment of postoperative abdominal abscesses even in complex cases such as loculated abscess or abscess associated with enteric fistula.     

Implementation of percutaneous dilation tracheotomy – value of preincisional ultrasonic examination?

BACKGROUND: In this observational study we have evaluated the implementation of percutaneous dilation tracheotomy (PDT), using the forceps dilation technique (Portex) in a multidisciplinary ICU. METHODS: We included a preincisional ultrasonic evaluation of the neck in order to visualise the isthmus glandula thyroidea and major vessels. The observational period comprised one year. PDT was performed in 28 patients. RESULTS: Implementation of PDT was uneventful. Duration of insertion was 10 min (4-40 min). Total time of tracheostomy was 8 days (1-65 days). In nine cases, the proximal end of the isthmus was overlying the space between the 1st and 2nd tracheal ring, which was considered the optimal insertion site. This resulted in seven cases of insertion between the cricoidea and the 1st tracheal ring and in two cases in a more distal insertion. Nineteen tracheotomies were performed in the interstice between the 1st and 2nd tracheal ring. In nine patients, major vessels were overlying the trachea. In none of the patients did this information result in an altered insertion site. Two cases of minor bleeding were observed; both stopped upon compression. In two patients the primary tube size (8.0) was too big and a smaller tube had to be inserted. In one patient the tube was maladapted to the stoma and had to be interchanged with an ordinary tracheostomial tube on the 5th day of tracheostomy. CONCLUSION: Based on the experience gathered in this study and information from the literature, we have abandoned the routine use of ultrasonic examination of the neck prior to PDT. In order to achieve and maintain routine, we suggest that the procedure is performed by a restricted number of doctors.     

Management of hangman’s fracture with percutaneous transpedicular screw fixation

Purpose

This study describes a percutaneous technique for C2 transpedicular screw fixation and evaluates its safety and efficacy in the treatment of patients with hangman’s fracture.

Methods

Ten patients with hangman’s fracture were treated by percutaneous C2 transpedicular screw fixation. There are six males and four females, who were, based on the classification of Levine and Edwards, sorted as follows: type I fracture, three cases; type II, five cases; type IIa, two cases. The causes of injury were road traffic accident in six patients and falling injury in four patients. Other associated lesions included rib fractures (7 patients), head injuries (4 patients), and fractures of extremities (6 patients).

Results

The new technique was performed successfully in all cases. The average operation time was 98 min (range 60–130 min) and the estimated blood loss was 25 ml (range 15–40 ml). No complications such as vascular or neural structures injuries were found intraoperatively. Postoperative CT scans demonstrated that 17 (85 %) of 20 screws were placed satisfactorily, and 3 (15 %) screws showed perforations of the pedicle wall (<2 mm). These patients were asymptomatic and no further intervention was required postoperatively. After 8–25 months follow-up (mean 15.3 months), solid fusion was demonstrated by computed tomography. All cases got well-sagittal alignment and no angulation or dislocation was found at the segment of C2–C3. There was no loss of fixation. Clinical examination showed a full range of motion in the neck in all patients.

Conclusions

The fluoroscopically assisted percutaneous C2 transpedicular screw fixation method is a technically feasible and minimally invasive technique for hangman’s fracture.     

Gastrostomy insertion in children: percutaneous endoscopic or percutaneous image-guided?

Background/Purpose

Gastrostomy insertion in children can be performed in many ways, but which is the best technique remains uncertain. This study evaluates the outcome of percutaneous endoscopic gastrostomy (PEG) and image-guided gastrostomy (IG).

Methods

We reviewed children who had either PEG (n = 136) inserted by pediatric surgeons or IG (n = 195) inserted by interventional radiologists in our hospital between May 2004 and July 2008. Gastrostomy-related complications were given scores ranging from 20 for major complications (eg, peritonitis, gastrointestinal bleed, and visceral injury) to 1 for minor (eg, site infection and tube migration), and total score per month of follow-up was calculated per patient.

Results

Conversion to laparoscopic or open gastrostomy was more frequent in PEG versus IG (P = .001). Fewer PEG patients (28%) had complications than did IG (47%) (P = .001). One PEG patient developed a gastrocolic fistula. In the IG group, 2 patients had transverse colon puncture, 1 had intraperitoneal tube detachment, and 1 had upper gastrointestinal bleeding. When scored and adjusted by length of follow-up, PEG had lower scores compared with IG, indicating a better outcome (P = .03). These findings were supported by zero-inflated Poisson regression analysis.

Conclusion

Major complications were rare and observed more frequently after IG. Minor complications were observed in both procedures but were significantly less common in PEG.     

Does previous open nephrolithotomy affect the outcome of percutaneous nephrolithotomy?

PURPOSE: To determine the effects of previous open nephrolithotomy on the results and morbidity of subsequent percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: Between March 2005 and January 2006, 89 patients underwent PCNL at our institution. We compared the patients who had had previous open surgery on the same kidney (group 1; n = 27) with those who had had no previous surgery (group 2; n = 62). The two groups did not differ significantly in age (45.4 v 44 years), stone burden (361.3 mm(2) v 482.4 mm(2) ), stone number, or laterality. Operative time, hospital stay, success rate, visual analog pain scores 8 hours after surgery, analgesic doses (diclofenac sodium), and intraoperative and postoperative complications were compared. RESULTS: There were no differences in operating time, postoperative analgesic doses, pain scores, intraoperative and postoperative complications, the number of accesses, or the stone-free rate. CONCLUSIONS: The morbidity and efficacy of PCNL are similar in patients who have had previous open nephrolithotomy and those having no previous surgery. Previous open surgery does not affect the success of PCNL.     

A National comparison of surgical versus percutaneous drainage of pancreatic pseudocysts: 1997–2001

Case series results indicate that a surgical approach is superior to percutaneous drainage of pancreatic pseudocysts. To determine if this surgical advantage is persistent, national outcomes for both approaches were compared from 1997 through 2001. The National Inpatient Sample, a 20% sample of all nonfederal hospital discharges, was searched for patients who had a pancreatic pseudocyst diagnosis, an ICD-9 diagnosis code 577.2, and an ICD-9 procedure code of 52.01 for percutaneous drainage (PD) or 52.4 and 52.96 for the surgical approaches. Variables were compared by using either t test or x² analysis. Confounding variables were controlled for by linear or logistic regression models. No clinically significant demographic, comorbidity, and disease-specific severity-of-illness differences existed between the two groups. Significant differences in complications, length of stay (15 ± 15 versus 21 ± 22 days, P < 0.0001), and inpatient mortality (5.9% versus 2.8%, P < 0.0001) favored the surgical approach. In addition, endoscopic retrograde cholangiopancreatography use had a protective effect on mortality (odds ratio, 0.7), whereas percutaneous drainage had an increased risk of mortality (odds ratio, 1.4). This populationbased study suggests that surgical drainage of pancreatic pseudocysts, particularly when coupled with use of endoscopic retrograde cholangiopancreatography, leads to decreased complications, length of stay, and mortality in comparison with percutaneous drainage.

Utility of the Guy’s Stone Score in predicting different aspects of percutaneous nephrolithotomy

Objective

To evaluate Guy’s scoring system (GSS) as a grading system for complexity of kidney stone before percutaneous nephrolithotomy (PCNL) as a predictor for different items of outcome.

Is percutaneous repair of the Achilles tendon a safe technique? A study of 124 cases

Ma and Griffith first described in 1977 a percutaneous technique for the repair of acute Achilles tendon rupture. In 1992, Delponte popularised a new percutaneous technique with Tenolig. The authors report a series of 124 cases of Achilles tendon rupture treated with Tenolig in their institution from 1993 to 1998. There were 79 men and 45 women. The mean age was 41.5 years, with a peak from 30 to 39 years. The rupture occurred during sports activities in 69 cases. The mean duration of follow-up was 1.9 years. Surgical complications noted were: unbending of one of the harpoon wires in 5 cases, rupture of the harpoon wire in one case and tendon re-rupture in 12 cases. The rate of re-rupture was similar to the rate noted with conservative treatment (10%). Skin necrosis at the entrance wound was noted in 10 cases, and injury of the sural nerve in 8 cases. Full weight-bearing without crutches was regained for 95% of patients within 3 months. In conclusion, this report shows a high rate of re-rupture and sural nerve entrapment with percutaneous surgery (Tenolig). The high rate of re-rupture can be due to the progressive but immediate weight-bearing allowed without an orthosis, or to inadequate apposition of the tendon ends, or to delay before repair. The high rate of sural nerve entrapment is due to its proximity to the Achilles tendon. We believe that a limited open technique is more reliable and has the advantage of allowing direct visualisation of the repair site and controlling adequate apposition of the tendon ends.     

Management of afferent loop obstruction: Reoperation or endoscopic and percutaneous interventions?

Afferent loop obstruction is a purely mechanical complication that infrequently occurs following construction of a gastrojejunostomy. The operations most commonly associated with this complication are gastrectomy with Billroth II or Roux-en-Y reconstruction, and pancreaticoduodenectomy with conventional loop or Roux-en-Y reconstruction. Etiology of afferent loop obstruction includes: (1) entrapment, compression and kinking by postoperative adhesions; (2) internal herniation, volvulus and intussusception; (3) stenosis due to ulceration at the gastrojejunostomy site and radiation enteritis of the afferent loop; (4) cancer recurrence; and (5) enteroliths, bezoars and foreign bodies. Acute afferent loop obstruction is associated with complete obstruction of the afferent loop and represents a surgical emergency, whereas chronic afferent loop obstruction is associated with partial obstruction. Abdominal multiple detector computed tomography is the diagnostic study of choice. CT appearance of the obstructed afferent loop consists of a C-shaped, fluid-filled tubular mass located in the midline between the abdominal aorta and the superior mesenteric artery with valvulae conniventes projecting into the lumen. The cornerstone of treatment is surgery. Surgery includes: (1) adhesiolysis and reconstruction for benign causes; and (2) by-pass or excision and reconstruction for malignant causes. However, endoscopic enteral stenting, transhepatic percutaneous enteral stenting and direct percutaneous tube enterostomy have the principal role in management of malignant and radiation-induced obstruction. Nevertheless, considerable limitations exist as a former Roux-en-Y reconstruction limits endoscopic access to the afferent loop and percutaneous approaches for enteral stenting and tube enterostomy have only been reported in the literature as isolated cases.     

Chronic rupture of Achilles tendon: is the percutaneous suture technique effective?

Background We report the long-term results of the surgical treatment of chronic rupture of the Achilles tendon using percutaneous suturing under local anesthesia. Patients and methods We operated on 22 patients with median age of 50 years (29–72) with chronic rupture of Achilles tendon between 1991 and 2005. The median time from injury to surgery was 7.1 weeks (4–40). We used percutaneous surgical technique similar to a technique described by Ma and Griffith (1977, Clin Orthop Relat Res 128:247–255) and Kosanović (1994, Arch Orthop Trauma Surgery 113:177–179). Eighteen (82%) patients attended the clinical review at a mean of 67 months (14–176). During follow up, patients were asked about pain, stiffness, weakness of the calf, footwear restrictions, occupation and level of activity before and after injury (Tegner score), influence of injury on ADL activities and satisfaction with treatment. The passive and active range of movement of the ankle and the power of isometric plantar flexion were measured, and the endurance test was performed. Functional assessment was performed using a Leppilahti clinical scoring scale and a modified Merkel score Results Complete healing of the tendon was achieved in 21 patients (95%). In 17 patients (77%) the postoperative course was complications free. There were no reruptures during the observation period. All were able to stand on the tiptoe of the injured leg. The operated leg had a mean of 87.5% of the isometric power compared with the uninjured leg (p = NS). On an average they could stand on toes and raise the heel 13 times on side with the ruptured tendon. The Leppilahti scoring scale revealed a result that was excellent for 11 patients (62%), good for 2 (11%), fair for 5 (28%) and no one had poor result. The average score was 83.3 (60–100). Eighty-three percent of patients stated that the result of surgery was very good and 11% rated it as good. Fourteen patients (78%) returned to same level of activity at median 7 months after surgery. Conclusions Our series is one of the largest to be reported for the treatment of chronic rupture. Our technique offers a considerable advantage; it is minimal invasive, easy to perform with no associated harvesting morbidity and increased patient acceptance. We recommend this technique for the treatment of chronic rupture of Achilles tendon.

A nationwide examination of outcomes of percutaneous cholecystostomy compared with cholecystectomy for acute cholecystitis, 1998–2010

Background

Improvements in percutaneous drainage techniques combined with the recognized advantages of avoiding surgery in critically ill patients have rendered cholecystostomy an attractive treatment option, particularly in those patients with acute acalculus cholecystitis. However, robust data to guide surgeons in choosing cholecystostomy versus cholecystectomy have been lacking.

Methods

Retrospective analysis of the Nationwide Inpatient Sample (NIS) database from 1998–2010 was performed. Patients identified as having acute cholecystitis (calculus and acalculus) were identified by ICD-9 diagnosis codes and further classified as having undergone cholecystostomy or cholecystectomy. Patients with both procedures were included in the cholecystectomy group. Patients with neither procedure and those younger than age 18 years were excluded. Multivariate analyses examined mortality, length of stay, total charges, gallbladder/gastrointestinal complications, or any complication. Results were adjusted for age, race, gender, Charlson comorbidity index, and teaching-hospital status. Subset analyses were performed among patients who survived and patients who died.

Results

A total of 248,229 calculus and 58,518 acalculus acute cholecystitis patients were analyzed. On unadjusted analysis, mortality, length of stay, and total charges were higher, but complication rates were lower, in patients with a cholecystostomy. Adjusted analysis showed lower odds of complications [calculus: odds ratio (OR) 0.3, p < 0.001; acalculus: OR 0.4, p < 0.001] but higher odds of mortality, total charges, and LOS (calculus: mortality OR 5.2, p < 0.001, $29,113, p < 0.001, +5.1 days, p < 0.001; acalculus: mortality OR 3.7, p < 0.001; $43,771, p < 0.001, +6.2 days, p < 0.001) among patients who received cholecystostomy. Results were similar in subset analyses.

Conclusions

Patients receiving cholecystostomy were more likely to be older and have more comorbidities. Among patients with calculus or acalculus cholecystitis, patients with cholecystostomy had decreased complication rates compared with patients with cholecystectomy. However, patients who received cholecystostomy had increased odds of death, longer length of stay, and higher total charges.     

Efficacy of TiRobot-assisted minimally invasive percutaneous screw fixation for pelvic fractures北大核心CSCD

Objective To investigate the clinical efficacy of TiRobot-assisted minimally invasive percutaneous screw fixation for pelvic fractures. Methods The clinical data of 44 patients with pelvic fracture were retrospectively analyzed who had undergone TiRobot-assisted minimally invasive percutaneous screw fixation from May 2018 to April 2021 at Department of Orthopedic Traumatology, The First Hospital of Jilin University. There were 30 males and 14 females, aged from 11 to 78 years (average, 40. 6 years). According to the Tile classification, there were 20 type CI fractures, 23 type C2 fractures and one type C3 fracture. The time from injury to operation averaged 8. 2 days (from 1 to 41 days). The minimally invasive percutaneous screw fixation was assisted by the orthopaedic TiRobot in all patients. Operation time, fluoroscopy time, reduction quality, complications and functional recovery at the final follow-up were recorded and analyzed. Results A total of 96 screws were implanted in this cohort. The total fluoroscopy time ranged from 17 to 66 s, with an average of 17. 8 s for each single screw. The operation time ranged from 50 to 355 min, averaging 179. 7 min. According to the Matta criteria, the reduction quality was rated as excellent in 36 cases, as good in 5 and as fair in 3, yielding an excellent and good rate of 93. 2% (41/44). All the 44 patients were followed up for 6 to 42 months (average, 20. 4 months). The fracture healing time ranged from 2 to 6 months, averaging 3. 3 months. The Majeed scores at the final follow-up ranged from 51 to 100 points (average, 83. 7 points); there were 28 excellent, 8 good, 7 fair and one poor cases, giving an excellent to good rate of 81. 8% (36/44). Follow-up found no such complications as iatrogenic neurovascular injury, incision infection, malunion, implant loosening or fracture re-displacement in all the 44 patients. Conclusion TiRobot-assisted minimally invasive internal fixation can result in fine clinical efficacy for pelvic fractures, showing advantages of accuracy, minimal invasion and safety. © The Author(s) 2023.     

Is the bleeding time predictive of bleeding prior to a percutaneous renal biopsy?

The bleeding time is used by many nephrologists to predict risk of hemorrhage before percutaneous kidney biopsy. Developed in 1910, the bleeding time is a nonspecific test that may be prolonged in multiple disease states. When accompanied by a platelet count, hematocrit, and a thorough investigation of family or personal history of bleeding, the bleeding time is the best predictor of hemorrhagic risk in patients with kidney disease. Because there is a small but significant risk of bleeding with percutaneous kidney biopsy, a prolonged bleeding time should be treated with 1-deamino-8-D-arginine vasopressin, cryoprecipitate, estrogens, or dialysis as indicated before biopsy. Treating all patients with 1-deamino-8-D-arginine vasopressin without checking bleeding times may be cost-ineffective when compared with treating only those patients with prolonged bleeding times.     

Higher incidence of new vertebral fractures following percutaneous vertebroplasty and kyphoplasty--fact or fiction?

New vertebral fractures after percutaneous vertebroplasty or kyphoplasty are said to result from biomechanical changes induced by cementation. Fact or fiction? The reported incidences for new vertebral fractures after cementation or after conservative therapy vary widely. This is mainly due to differences in their design, more specifically as to the duration of followup. Therefore a systematic review of the literature was performed, searching for comparable publications to assess the potential risk of new vertebral fractures following vertebroplasty and kyphoplasty versus conservative treatment. Studies were only included if they granted a standardized one-year radiological follow-up, so improving comparability. However, a high degree of heterogeneity was still seen among the results, which made it impossible to state that cement augmentation is as safe as conservative treatment with respect to new fractures. In other words, it was impossible to separate facts from fiction with the studies available to-day. The combined odds ratio of vertebroplasty and kyphoplasty versus conservative treatment, namely 0.96, gave a hint that there might be little difference. Large scale randomized studies will be necessary.     

What is the relevance of percutaneous endoscopic gastrostomy on the survival of patients with amyotrophic lateral sclerosis?

Percutaneous endoscopic gastrostomy (PEG) is a standard procedure for feeding dysphagic amyotrophic lateral sclerosis (ALS) patients. Nevertheless, the effect of prognostic factors influencing survival after PEG remains unclear. We aimed to evaluate the prognostic value of several clinical features on survival after PEG placement. This study investigated 151 patients with ALS, in whom a PEG was inserted over the last 16 years in our centre. Survival curves were determined by Kaplan-Meier and the analysis of potential prognostic factors was performed by a Cox regression model. The overall median survival was 32 months, longer in spinal-onset disease patients - 42 vs. 29 months in bulbar-onset patients (p 相似文献
