Is Percutaneous Repair Better Than Open Repair in Acute Achilles Tendon Rupture?

Background  

Open repair of Achilles tendon rupture has been associated with higher levels of wound complications than those associated with percutaneous repair. However, some studies suggest there are higher rerupture rates and sural nerve injuries with percutaneous repair.     

Repair of Giant Midline Abdominal Wall Hernias: “Components Separation Technique” versus Prosthetic Repair

BACKGROUND: Reconstruction of giant midline abdominal wall hernias is difficult, and no data are available to decide which technique should be used. It was the aim of this study to compare the "components separation technique" (CST) versus prosthetic repair with e-PTFE patch (PR). METHOD: Patients with giant midline abdominal wall hernias were randomized for CST or PR. Patients underwent operation following standard procedures. Postoperative morbidity was scored on a standard form, and patients were followed for 36 months after operation for recurrent hernia. RESULTS: Between November 1999 and June 2001, 39 patients were randomized for the study, 19 for CST and 18 for PR. Two patients were excluded perioperatively because of gross contamination of the operative field. No differences were found between the groups at baseline with respect to demographic details, co-morbidity, and size of the defect. There was no in-hospital mortality. Wound complications were found in 10 of 19 patients after CST and 13 of 18 patients after PR. Seroma was found more frequently after PR. In 7 of 18 patients after PR, the prosthesis had to be removed as a consequence of early or late infection. Reherniation occurred in 10 patients after CST and in 4 patients after PR. CONCLUSIONS: Repair of abdominal wall hernias with the component separation technique compares favorably with prosthetic repair. Although the reherniation rate after CST is relatively high, the consequences of wound healing disturbances in the presence of e-PTFE patch are far-reaching, often resulting in loss of the prosthesis.     

Why Repair the Subscapularis? A Logical Rationale

Tears of the subscapularis tendon are now more frequently recognized and are often associated with tears of the posterosuperior rotator cuff tendons. This has been facilitated by arthroscopic approaches, and repair techniques have been developed. In the setting of a rotator cuff repair, when a subscapularis tendon tear is found in continuity with a supraspinatus tendon tear, it is essential to recognize how the repair of both tendon tears can influence the overall security of the entire repair construct. When a repairable subscapularis tendon tear is left unrepaired, the function of the subscapularis muscle will be lost. In addition, the posterosuperior rotator cuff tear will be more difficult to repair, and it will be less securely repaired. When the subscapularis tendon is repaired initially, the posterosuperior rotator cuff repair can be more easily and more reliable achieved.     

Repair of bilateral inguinal hernias--sequential or simultaneous?

INTRODUCTION: Surgery of inguinal hernia has changed dramatically with the introduction of tension-free hernia repair. There is still some controversy regarding the treatment of bilateral inguinal hernia, but simultaneous operation has gained popularity. The purpose of the present paper is to evaluate recent publications regarding treatment of bilateral inguinal hernia. METHODS: For this article, the "Cochrane Database of Systematic Reviews", "BMJ Clinical Evidence", "Pubmed" and "Embase" were searched using the search terms "simultaneous", "bilateral", "inguinal" and "hernia". Number of patients, recurrence rate, complications, study type and authors' conclusions were evaluated. Analysis of the literature showed relevant results in two reviews of the "Cochrane Database", 4 items in "BMJ Clinical Evidence" and 17 clinical studies. RESULTS: No study showed a difference between recurrence and complication rate (simultaneous bilateral vs. unilateral repair). Recurrence rates were from 0.3 to 19 % (bilateral) and from 0.7 to 15 % (unilateral). Complications were defined heterogeneously and were in a range from 2.5 to 26.7 % (bilateral) and from 3 to 21 % (unilateral). All operative procedures (open suture: Shouldice; open mesh: Lichtenstein, Stoppa; laparoscopic techniques: TAPP / TEP) are adequate for the repair of bilateral hernia. CONCLUSION: The simultaneous operation of bilateral hernia is safe and effective. Postoperative pain and length of reconvalescence are comparable to those of the unilateral operation. Only symptomatic bilateral groin hernias should be operated. If no difficulties such as obesity and giant hernia are expected, bilateral hernias should be repaired simultaneously. The choice of the operative method should be made in accordance to the centre's standard procedure. A special operation for bilateral hernias is neither necessary nor justified.     

Barbed Sutures and Tendon Repair—a Review

Introduction

Traumatic tendon lacerations are a common problem encountered by hand surgeons worldwide. Although the use of barbed suture to repair tendon lacerations has gained theoretical popularity in recent years, there is little information available regarding the safety, efficacy, longevity, or complications encountered when used in tenorraphy. In this study, we review the available literature on the use of barbed suture in tendon repair.

Methods

Studies conducted between 1980 and 2014 were identified using several databases, including EMBASE, SCOPUS, MEDLINE, and Web of Science. Keywords used to search for appropriate studies included the following: barbed, v loc, quill, tendon, tendon injuries, suture, tenorraphy, injury, and laceration, in various combinations.

Results

Our initial literature search identified 47 articles, and 8 were deemed appropriate for review after applying our exclusion criteria. The data from each of the articles is reviewed for the following major categories:

1. Maximum load to failure
2. Mode of failure
3. Load to 2-mm gap
4. Change in cross-sectional area
5. Type of repair

Conclusions

Barbed suture tenorraphy has a myriad of theoretical advantages, supported by varying ex vivo studies, as compared to traditional techniques. However, due to the non-uniformity in current studies and the lack of available data in a live model, we are unable to argue for or against barbed suture tenorraphy. We believe our review provides the most in-depth analysis of barbed suture tenorraphy to date, illuminates the potential advantages of using barbed sutures, and highlights the need for further investigation into this technique.     

Proceed? Mesh for Laparoscopic Ventral Hernia Repair

Background and Objectives:

Laparoscopic technique to repair ventral hernia offers advantages over conventional open surgery such as shorter recovery time, decreased pain, and lower recurrence rates. There are a myriad of meshes available for laparoscopic repair of ventral hernias. This study evaluated the outcomes of laparoscopic repair of ventral hernias with Proceed mesh (Ethicon, Somerville, NJ, USA) in a single academic institution.

Methods:

An institutional review board–approved retrospective review was performed for 100 consecutive patients with ventral hernia who underwent a laparoscopic approach at our institution from August 2006 to February 2009. All patients were operated on by a single surgeon using a standard technique with transabdominal suture fixation and tacks.

Results:

The study included 100 consecutive patients (57 female and 43 male patients). The mean age was 55 years (range, 16–78 years), and the mean body mass index was 33.3 kg/m² (range, 19.6–68.9 kg/m²). Of the repairs, 27% were performed for a recurrent hernia. The mean and median size of the defect were 128 cm² and 119.5 cm² (range, 4–500 cm²), respectively. To ensure appropriate mesh overlap, the mean size of mesh was 253 cm² (range, 36–700 cm²). There were 4 conversions. The mean operative time was 117 minutes (range, 35–286 minutes). The mean length of stay was 1.9 days. There were no major abdominal complications. With a mean follow-up period of 50 months (range, 38–68 months), we have not recorded any recurrences. No mesh-related complications have been documented.

Conclusions:

The laparoscopic approach to ventral hernia repairs using Proceed mesh is associated with a low conversion rate and no major complications. At 50 months of follow-up, the recurrence rate is 0%. There were no mesh-related complications.     

Is Therapy Necessary After Distal Biceps Tendon Repair?

The EndoButton technique of distal biceps tendon repair provides strong biomechanical fixation. This strength of fixation may allow earlier postoperative range of motion (ROM). A retrospective review of 15 male patients undergoing single incision EndoButton repairs was used. Six subjects participated in conventional supervised postoperative rehabilitation while nine subjects were allowed unrestricted ROM after 2 weeks. Final ROM, time to full ROM, and Disabilities of Arm Shoulder and Hand (DASH) scores were compared. There was a significant difference for time to full ROM (p < 0.05). The mean time to full ROM was 8.67 weeks for the supervised therapy group and 4.38 weeks for the unrestricted group. There were no reruptures in either group. There were no significant differences in final ROM or DASH scores. These data suggest that unrestricted ROM results in a quicker return to full ROM without an increased risk of rerupture.     

Is Acromioplasty Ever Indicated During Rotator Cuff Repair?

Based on data from a national healthcare insurance carrier in the United States between 2010 and 2012, orthopedic surgeons performed an acromioplasty procedure on 73 to 76% of their arthroscopic rotator cuff repairs. This has remained a prevalent arthroscopic adjunct despite the controversies disputing the role and etiology of external impingement on symptomatic rotator cuff disease. Within the past decade, several randomized studies have demonstrated negligible benefits with acromioplasty performed alongside rotator cuff repair, with no significant differences in either patient-reported outcome scores or retear rates). Conversely, other authors have suggested higher rates of reoperation with rotator cuff repair alone. Critical shoulder angle, an objective measure of lateral acromion extension and glenoid inclination that is considered a gauge of external impingement, has demonstrated an association with rotator cuff tears; Despite this, patient-reported outcomes do not consistently correlate with critical shoulder angle or other variants in acromial morphology after arthroscopic full-thickness rotator cuff repair. Evidenced-based data is currently lacking to support routine use of acromioplasty in all cases of rotator cuff repair. However, the current available studies do present design flaws, namely statistical underpowering, particularly in type III acromion morphology; inadequate short-term follow-up; lack of imaging data to assess cuff healing; and insensitive outcome measures to capture the theorized benefits of subacromial decompression. Additionally, several relevant merits of acromioplasty have been reported, including decreased abrasive wear with prominent type III acromial morphology, release of natural growth factors to improve rotator cuff healing, and improved visualization during rotator cuff repair. Further evaluation is needed to determine the correct indications for acromioplasty in the setting of cuff repair. Current data would indicate that acromioplasty can be used safely at the discretion of the operating surgeon based on preoperative and intraoperative findings.     

Inguinal Hernia Repair: Local or General Anaesthesia?

INTRODUCTION

Specialist hernia centres and public hospitals with a dedicated hernia service (Plymouth Hernia Service) have achieved remarkable results for inguinal hernia repair with the use of local anaesthesia and set the standards for groin hernia surgery. There is minimal data in the literature as to whether such results are reproducible in the National Health Service in the UK.

PATIENTS AND METHODS

A retrospective analysis of all inguinal hernia repairs performed in one district general hospital over a 9-year period was performed. The outcome measures were type of anaesthesia used, early and late postoperative complications and recurrence. A postal questionnaire survey was conducted to obtain satisfaction rates. In addition, a postal questionnaire survey of consultant surgeons in Wales was performed to determine the use of local anaesthesia and day-case rates for inguinal hernia repair.

RESULTS

A total of 577 hernia repairs were performed during the study period. Of these, 369 (64%) repairs were performed under local anaesthesia (LA) and 208 (36%) under general anaesthesia (GA). Day-case repair was achieved in 70% (400) of cases. The day-case rates were significantly higher under LA compared to GA (82.6% versus 42.6%; P < 0.05). Patients operated under LA had lower postoperative analgesic requirements and lower incidence of urinary retention compared with the GA group (P < 0.05). There were 7 (1.2%) recurrences at a median follow-up of 5.1 years (range, 10.3–2.5 years). Postal questionnaire revealed higher satisfaction rates with LA compared to GA repair. Only 15% of surgeons in Wales offer the majority of their patients local anaesthetic repair.

CONCLUSIONS

The use of LA results in increased day-case rates, lesser postoperative analgesic requirements and fewer micturition problems. The excellent results obtained by specialist hernia centres can be reproduced by district general hospitals by increasing the use of LA to repair inguinal hernias.     

Should Elective Repair of Intrathoracic Stomach be Encouraged?

Background  

Given our aging population, patients with an intrathoracic stomach are an increasing clinical problem. The timing of repair remains controversial, and most reports do not delineate morbidity of emergent presentation. The aim of the study was to compare the morbidity and mortality of elective and emergent repair.     

Endovascular Thoracic Aortic Repair and Previous or Concomitant Abdominal Aortic Repair: Is the Increased Risk of Spinal Cord Ischemia Real?

Spinal cord ischemia after endovascular thoracic aortic repair remains a significant risk. Previous or concomitant abdominal aortic repair may increase this risk. This investigation reviews the occurrence of spinal cord ischemia after endovascular repair of the descending thoracic aorta in patients with previous or concomitant abdominal aortic repair. Over an 8-year period, 125 patients underwent endovascular exclusion of the thoracic aorta at the Mount Sinai Medical Center. Twenty-eight of these patients had previous or concomitant abdominal aortic repair. The 27 patients who underwent staged repairs all had cerebrospinal fluid (CSF) drainage during and following repair. This population was analyzed for the complication of spinal cord ischemia and factors related to its occurrence. Mean follow-up was 19.3 months (range 1-61). Spinal cord ischemia developed in four of the 28 patients (14.3%) who underwent endovascular thoracic aortic repair with previous or concomitant abdominal aortic repair, while one of 97 patients (1.0%) developed ischemia among the remaining thoracic endograft population. One patient with concomitant abdominal aortic repair developed cord ischemia that manifested 12 hr following the procedure. The remaining three patients with previous abdominal aortic repair developed more delayed-onset paralysis ranging from the third postoperative day to 7 weeks following repair. Irreversible cord ischemia occurred in three patients, with full recovery in one patient. Major complications from CSF drainage occurred in one patient (3.7%). Spinal cord ischemia occurred at a markedly higher rate in patients with previous or concomitant abdominal aortic repair. This risk continued beyond the immediate postoperative period. The benefit of perioperative and salvage CSF drainage remains to be determined.
