The importance of submalleolar deformity in determining leg length discrepancy

Background and purposeThe association of leg length discrepancy (LLD) with a number of clinical disorders has made its determination a significant part of the physical examination. We believe that submalleolar causes of LLD may be under-acknowledged. The most common clinical method used to measure LLD is by tape from the anterior superior iliac spine (ASIS) to medial malleolus which disregards the potential for LLD arising from asymmetry in the foot distal to the tibiotalar joint.MethodsThe present pilot study involves a group of 5 volunteers (experimental group) and a group of 3 patients with flexible flat feet (clinical study). The differences in tibial tubercle height from the ground between full pronation and full supination were measured using the CODA MPX 30^® system (Charnwood Dynamics Limited, Leicestershire, England). Correlations of the patterns within each group were produced.ResultsA significant relationship with leg lengths was found in the experimental group when they induced maximum pronation (R-squared = 0.62, p = 0.007) while an inverse relationship occurred with supination, although marginally significant (R-squared = 0.37, p = 0.064).ConclusionsWe have demonstrated that significant leg length discrepancy can occur in patients who do not have obvious deformity when non weight bearing. We recommend using the blocks method routinely. Appropriately measuring LLD is of vital importance to properly diagnosing and treating patients with unequal leg lengths or related symptoms.     

Minilaparoscopic appendectomy using a new spiral needle

Background

Acute appendicitis is the most frequent abdominal disease and requires urgent surgery. At the present time, laparoscopic appendectomy is a well-accepted emergency procedure at most centers. In this study, we used a new spiral needle to facilitate the procedure, making it easy, minimally invasive, and cost effective.

Methods

The study included 70 patients of both sexes with acute appendicitis that was treated by laparoscopic appendectomy using a new spiral needle. These cases were treated at the General Surgery Department, Zagazig University, Egypt, from May 2012 to August 2013. In the procedure we used only two ports (a 10-mm port directly below the umbilicus for the camera and a 5-mm port at the left iliac fossa at the midclavicular line). The new spiral needle was used to hold the appendix during the procedure and was inserted into the right iliac fossa depending on the site of the appendix.

Results

The mean age of the patients was 27.3 years, mean operative time was 40 min, and mean hospital stay was 1.3 days. Ten patients (14 %) had minimal bleeding at the site of needle passage into the mesoappendix. Wound infection at the site of umbilical port occurred in four patients (5.7 %) postoperatively.

Conclusion

Laparoscopic appendectomy using our new spiral needle is easy, minimally invasive, and cost effective.     

Volume of Resected Stomach as a Predictor of Excess Weight Loss After Sleeve Gastrectomy

Background

Laparoscopic sleeve gastrectomy (LSG) is gaining popularity for the treatment of obesity. The objective of this study was to evaluate the volume of the resected stomach (VRS) as a predictor of the percentage of excess weight loss (%EWL) 1 year after LSG.

Methods

This was a single-surgeon study of prospectively collected data of patients who underwent LSG at Jordan University Hospital (February 2009 to February 2012). The VRS was measured using a standardized technique. The %EWL was calculated at 3, 6, and 12 months postoperatively. The correlation between the VRS and %EWL was statistically evaluated.

Results

Ninety patients underwent LSG during the study period. Of these, 73 patients (57 female) completed at least 1 year of follow-up and were analyzed; their body mass index was 45?±?7.6 kg/m² (33–81). The VRS was 1,337.4?±?435.2 ml (600–2,800). The %EWL was 33.6?±?11.1 % at 3 months, 48.6?±?15.5 % at 6 months, and 56.8?±?18.9 % at 12 months. A significant correlation was observed between the VRS and %EWL at 1 year (p?=?0.003). Patients with a VRS of >1,100 ml (n?=?43) achieved significantly greater %EWL at 12 months than did those with a VRS of ≤1,100 (n?=?30). Removal of >1,100 ml of gastric volume was associated with a sensitivity and specificity of 75.5 and 46.2 %, respectively, for achieving a %EWL of ≥50 %.

Conclusion

The VRS can be used as an indicator of excess weight loss 1 year after LSG.     

Surgeon-performed ultrasound in the ICU setting

Evaluation of critically ill patients is often challenging due to altered sensorium, underlying disease, and the presence of multiple drains or monitoring devices. In such circumstances, the ability of physicians to perform ultrasound examinations in the intensive care unit provides a useful diagnostic and therapeutic adjunct. In this article,we review the application of surgeon-performed ultrasonography in the evaluation and management of critically ill patients.     

Cemented bipolar hemiarthroplasty with a cerclage cable technique for unstable intertrochanteric hip fractures in elderly patients

Aim

The purpose of this study is to evaluate the clinical and radiological outcomes of cemented bipolar arthroplasty as a primary treatment for unstable intertrochanteric fracture in the elderly patients.

Methods

Twenty hips with unstable intertrochanteric fractures were followed for more than 2 years after cemented bipolar hemiarthroplasty. The mean age was 69 years, and the mean follow-up period was 30.5 months. We evaluated the results by Harris hip score, complications, and radiologic findings.

Results

At the last follow-up, the mean Harris hip score was 83.3 points. Radiologically, there was no case of osteolysis. All stems were stable without significant changes in alignment or progressive subsidence.

Conclusions

Bipolar hemiarthroplasty with calcar reconstruction is a good option for unstable intertrochanteric fractures in elderly patients with severe osteoporosis with strict indication selection. Longer-term studies with larger numbers of patients are required to address the issues of late complications.     

Relationship between peripheral and central venous pressures in different patient positions, catheter sizes, and insertion sites

OBJECTIVE: To investigate the relationship between peripheral and central venous pressures in different patient positions (supine, prone, lithotomy, Trendelenburg, and Fowler), different catheter diameters (18 G and 20 G), and catheterization sites (dorsal hand and forearm) during surgical procedures. DESIGN: Prospective clinical study. SETTINGS: University hospital. PARTICIPANTS: Five hundred adult patients. INTERVENTIONS: Peripheral over-the-needle intravenous catheters were placed in the dorsal hand or forearm. Central venous catheters were inserted via the internal jugular or subclavian vein after induction of anesthesia. MEASUREMENTS and MAIN RESULTS: Simultaneous measurements of central and peripheral venous pressures were made during stable conditions at random time points in surgery; 1953 paired measurements were performed. Mean central venous pressure was 11 +/- 3.7 mmHg and peripheral venous pressure was 13 +/- 4 mmHg (p = 0.0001). The overall correlation between central venous and peripheral venous pressures was found to be statistically significant (r = 0.89, r(2) = 0.8, p = 0.0001). Mean difference between peripheral and central venous pressure was 2 +/- 1.8 mmHg. Ninety-five percent limits of agreement were 5.6 to -1.6 mmHg. CONCLUSION: It has been assumed that replacing central venous pressure by peripheral venous pressure would cause problems in clinical interpretation. If the validity of this data is confirmed by further studies, the authors suggest that central venous pressure could be estimated by using regression equations to compare the 2 methods.     

Comparative Study of Conventional Lateral Internal Sphincterotomy, V-Y Anoplasty, and Tailored Lateral Internal Sphincterotomy with V-Y Anoplasty in the Treatment of Chronic Anal Fissure

Background

Lateral internal sphincterotomy has been proven highly effective in curing anal fissure but with a high incidence of postoperative incontinence.

Objective

We compared conventional lateral internal sphincterotomy, V-Y advancement flap, and combined tailored lateral internal sphincterotomy with V-Y advancement flap in treating anal fissure.

Patients

Consecutive patients treated for anal fissure at our colorectal unit were evaluated for inclusion. Participants were randomly allocated to receive conventional sphincterotomy (GI), V-Y advancement flap (GII), or combined tailored lateral sphincterotomy with V-Y advancement l flap (GIII).

Main Outcome Measures

The primary outcome measure was the incontinence rate; secondary outcomes included healing rate, operative time, anal manometery, and recurrence rate.

Results

One hundred fifty patients with chronic anal fissure were randomized. Healing rate after 1?year was 84?% in GI, 48?% in GII, and 94?% in GIII, respectively (P?=?0.001). The recurrence rate was 4?% in G1, 22?% in GII, and 2?% in GIII (P?=?0.01). Incontinence rate was 14?% in GI, 0?% in GII, and 2?% in GIII (P?=?0.03).

Conclusion

Although all three procedures are simple and easy to perform, tailored lateral internal sphincterotomy with V-YF appears to produce the greatest healing rate, with the fewest complications and less rate of recurrence.     

Management of Failed and Infected First Metatarsophalangeal Joint Implant Arthroplasty by Reconstruction with an Acellular Dermal Matrix: A Case Report

Management of failed first metatarsophalangeal joint implant arthroplasty, especially in the face of infection, is an area of debate without a clear consensus. The purpose of the present report was to explore a new option of reconstructing the joint with an acellular dermal matrix substance in a single case study during a 12-month follow-up period. A staged approach that began with removal of the failed 2-component great toe implant, Koenig^®, excisional debridement of the wound with resection of the necrotic bone (proximal phalanx and distal portion of the first metatarsal bones), and culture-specific antibiosis therapy. The final stage included incorporating the acellular dermal matrix, Graftjacket^® into the joint in an accordion-type fashion, and reconstruction of the joint capsule. Postoperative radiographs revealed a more rectus joint with some improvement in length. At 6 months postoperatively, magnetic resonance imaging revealed incorporation of the graft material into the joint. Finally, at the 1-year mark, the patient was pain free with satisfactory function at the first metatarsophalangeal joint during gait. This is the first reported case of salvaging failed and infected first metatarsophalangeal joint implant arthroplasty with incorporation of the acellular dermal matrix and provides a new option to consider in the future.     

Highly unstable complex C3-type distal femur fracture: can double plating via a modified Olerud extensile approach be a standby solution?

Background

Multiplanar complex C3-type unstable distal femoral fractures present many challenges in terms of approach and fixation. This prospective study investigates a possible solution to these problems through double plating with autogenous bone grafting via a modified Olerud extensile approach.

Materials and methods

Twelve patients with closed C3-type injuries were included; eight of them were male, and their mean age was 33.5 years (range 22–44 years). Mechanism of injury was road traffic accident (RTA) in nine patients and fall from height in the other three cases. Eight cases were operated during the first week and four cases during the second week after injury. Mean follow-up was 13.7 months (range 11–18 months).

Results

Mean radiological healing time was 18.3 weeks (range 12-28 weeks), and all cases had good radiological healing without recorded nonunion or malunion. Clinically, two cases (16.7 %) had excellent results, five cases (41.7 %) had good results, three cases (25 %) had fair results, and two cases (16.7 %) had poor results. No cases developed skin necrosis, deep infection, bone collapse, or implant failure. However, two cases (16.7 %) had limited knee flexion to 90° and required subsequent quadricepsplasty.

Conclusions

Use of this modified highly invasive approach facilitated anatomical reconstruction of C3-type complex distal femoral fractures with lower expected complication rate and acceptable clinical outcome, especially offering good reconstruction of the suprapatellar pouch area. It can be considered as a standby solution for managing these difficult injuries.     

Hepatitis C Positive Grafts may be used in Orthotopic Liver Transplantation: A Matched Analysis

Hepatitis C (HCV)-positive liver grafts have been increasingly used in patients with decompensated liver disease from HCV because of critical shortage of available organs. Fifty-nine recipients of HCV-positive grafts were matched to patients who received HCV-negative grafts. All recipients were transplanted for HCV liver disease. Matching variables were (1) status, (2) pre-transplant creatinine, (3) recipient age, (4) donor age, (5) warm ischemia time, and (6) year of transplantation. Both unmatched and matched analyses were performed on patient survival, graft survival, and time to HCV recurrence. There was no significant statistical difference in patient, graft, or HCV recurrence-free survival between recipients of HCV-positive and HCV-negative grafts with matched and unmatched analyses (p > 0.05). The 3-year estimates of HCV disease-free survival were 12% (+/- 9%) and 19% (+/- 7%) using HCV-positive and -negative grafts, respectively. The use of HCV-positive grafts in recipients with HCV does not appear to affect patient survival, graft survival, or HCV recurrence when compared with the use of HCV-negative grafts. Our results suggest that HCV-positive grafts can be used in a HCV liver transplant recipient.
