Today, total knee arthroplasty (TKA) is one the most commonly performed surgeries worldwide. The purpose of this article is to review the appearance of normal post-TKA roentgenographs and describe the correct sequence for their interpretation. It is unwise to depend solely on patients' symptoms when diagnosing TKA complications because serial radiographs can foresee failures well before they manifest clinically. Ideal post-TKA radiographs comprise whole lower extremity anteroposterior and lateral views taken under weight bearing conditions along with a skyline view of the patellofemoral joint. Among other things, weight bearing exposes the true alignment, ligamentous laxity and polyethylene wear. On the basis of follow-up of our TKA cases, we have drawn up a protocol for assessing postoperative X-ray films after TKAs. Following the proposed sequence, surgeon can easily decide how to proceed with follow-up and foresee complications. Careful interpretation of postoperative radiographs after TKA is essential to careful monitoring of patients and implant survival.
BACKGROUND Jaundice is a frequent manifestation of biliary tract disorders and the evaluation and management of obstructive jaundice is a common problem faced by the general surgeon. During the last decade significant advances have been made in our understanding with regards to the pathogenesis, diagnosis, staging, and efficacy of surgical and nonsurgical management of obstructive jaundice. To diagnose the cause, site of obstruction, and management of a case of surgical jaundice is indeed a challenging task for the surgeon. Hence, a comprehensive study of the aetiology, clinical presentation, and management of obstructive jaundice is of paramount importance in the appropriate management of these patients. AIM This study evaluates the age and sex distribution, clinical presentation, aetiology, and the different modalities of treatment of obstructive jaundice. MATERIALS AND METHODS This prospective study was conducted in MKCG Medical College and Hospital, Berhampur, Odisha from September 2013-August 2015. Out of all surgical admissions from September 2013 to August 2015 in our hospital, 80 cases of surgical jaundice of different age group were selected randomly. A detailed history and clinical examination was done and appropriate investigations recorded. Patients were assessed preoperatively and later subjected to surgery or palliative procedure depending on the need. Postoperatively, patients' condition was assessed and complications were documented. Patients were followed up for mean period of 6 months where patients underwent surgical intervention/ERCP, any tissue removed was subjected for histopathological examination. RESULTS The occurrence of surgical jaundice was maximum in the 31-70 year age group. All patients presented with icterus and ultrasonogram was the most common investigation of choice. Most common cause of obstruction was choledocholithiasis followed by malignancy. CONCLUSION Commonest symptom of surgical jaundice in this study was pain abdomen and jaundice as per history. Commonest cause for surgical jaundice was found to be choledocholithiasis. Open exploration of common bile duct under experienced hands was found to be a good treatment modality in the management of obstructive jaundice.
BackgroundSeveral past clinical studies have demonstrated that frequent and unnecessary right ventricular pacing in patients with sick sinus syndrome and compromised atrio-ventricular conduction (AVC) produces long-term adverse effects. The safety and efficacy of two pacemaker algorithms, Ventricular Intrinsic Preference™ (VIP) and Ventricular AutoCapture (VAC), were evaluated in a multi-center study in pacemaker patients.MethodsWe evaluated 80 patients across 10 centers in India. Patients were enrolled within 15 days of dual chamber pacemaker (DDDR) implantation, and within 45 days thereafter were classified to either a compromised AVC (cAVC) arm or an intact AVC (iAVC) arm based on intrinsic paced/sensed (AV/PV) delays. In each arm, patients were then randomized (1:1) into the following groups: VIP OFF and VAC OFF (Control group; CG), or VIP ON and VAC ON (Treatment Group; TG). Subsequently, the AV/PV delays in the CG groups were mandatorily programmed at 180/150 ms, and to up to 350 ms in the TG groups. The percentage of right ventricular pacing (%RVp) evaluated at 12-month post-implantation follow-ups were compared between the two groups in each arm. Additionally, in-clinic time required for collecting device data was compared between patients programmed with the automated AutoCapture algorithm activated (VAC ON) vs. the manually programmed method (VAC OFF).ResultsPatients randomized to the TG with the VIP algorithm activated exhibited a significantly lower %RVp at 12 months than those in the CG in both the cAVC arm (39±41% vs. 97±3%; p=0.0004) and the iAVC arm (15±25% vs. 68±39%; p=0.0067). In-clinic time required to collect device data was less in patients with the VAC algorithm activated. No device-related adverse events were reported during the year-long study period.ConclusionsIn our study cohort, the use of the VIP algorithm significantly reduced the %RVp, while the VAC algorithm reduced in-clinic time needed to collect device data.
BackgroundIndian patients undergoing surgical aortic valve replacement (SAVR) differ from western populations with respect to aortic annulus size and valve disease morphology. The purpose of this post-market, non-randomized observational study was to evaluate the early hemodynamic performance of the Trifecta™ bioprosthesis (Abbott, previously St. Jude Medical, Minneapolis, US) in an Indian patient population.MethodsFrom January 2014 to September 2015, 100 patients (mean age 64.4 ± 7.1 years, 62% male) undergoing SAVR for valve disease (68% stenosis, 7% insufficiency, 25% mixed pathology) were enrolled across 10 centers in India. Patients implanted with a 19–27 mm Trifecta™ valve were eligible to participate and were prospectively followed for 12-months post-implantation. Echocardiographic hemodynamic performance was evaluated at pre-implant, pre-discharge and at 12-months by an independent core laboratory. Adverse events were adjudicated by the study sponsor. Functional status at 12-months was assessed according to NYHA classification. Continuous data was summarized using descriptive statistics (mean &standard deviation,) and categorical data was summarized using frequencies and percentages.ResultNinety patients (mean age 64.5, 62.2% male) completed the 12-month follow up. Significant improvements in hemodynamic valve performance were reported in 81 patients with available echocardiographic data at 12 months. Compared to baseline at 12-month follow up visit, mean effective orifice area increased from 0.75cm2 to 1.61cm2 (p < 0.0001), mean pressure gradient reduced to 10.42 mmHg from 51.47 mmHg (p < 0.0001), cardiac output increased from 4.46 l/min to 4.85 l/min (P 0.9254). Compared to baseline, functional status improved by ≥1 NYHA class in 75% of patients at 12 months (95% Clopper-Pearson (Exact) confidence limit [64.6%, 83.6%]). No instances of early mortality (< 30 days from index procedure) or structural valve dysfunction were reported.ConclusionIn an Indian patient population, implantation of the Trifecta™ bioprosthesis is shown to be safe and associated with favorable early hemodynamic performance and improved functional status at 12 months.Trial registrationThe clinical study has been registered under Clinical Trial Registry-India (http://www.ctri.nic.in) and registration number is CTRI/2014/02/004434 registered on 25 February 2014 retrospectively registered.
