Introduction In general surgery, open abdomen treatment (OAT) is used to treat abdominal compartment syndrome (ACS) and sepsis, often after a primary surgical procedure associated with complications. The results achieved in this patient population may depend on factors that are yet unknown. This study evaluates independent patient-related prognostic factors after OAT. Methods 38 clinical parameters and survival data of 165 consecutive general surgery patients after OAT were entered into a prospective database according to a defined algorithm in order to analyse the underlying surgical pathology, predictors of survival and important aspects of OAT-related morbidity...

Stereotactic body radiotherapy (SBRT) is an alternative to surgery for patients with early stage non-small cell lung cancer (NSCLC) who are inoperable due to comorbid disease or who refuse surgery. SBRT results in an excellent local control rate of more than 90%, which is comparable to surgery, while short and long-term overall toxicity is low. Surgically treated patients are often more extensively staged pre-operatively, e.g. with endobronchial ultrasound and/or mediastinoscopy, and typically undergo intra-operative lymph node dissection or sampling...

BACKGROUND: Most groin masses are first suspected to be groin hernias. More than 80% of bulging groin lesions are reportedly diagnosed as hernias by ultrasonography. Establishment of the correct diagnosis of hernia among all differential diagnoses is not easy. We herein describe a very rare case of groin eosinophilic funiculitis that presented as an irreducible groin hernia. CASE PRESENTATION: A 59-year-old man presented to our hospital with suspicion of a right groin hernia...

The incidence of lateral patella dislocations is high, particularly in young females. Beside traumatic cases, many patients present with specific anatomical factors that predispose to lateral patella dislocations (torsional abnormalities of the femur or the tibia, trochlea dysplasia, patella alta, etc). It is of utmost importance to correct those pathologic factors during concomitant procedures as isolated reconstructions of the medial patellofemoral ligament would fail in the presence of severe anatomic risk factors...

We present a rational, scientific, low-risk approach to patellofemoral pain (anterior knee pain) based on an understanding of tissue homeostasis. Loss of tissue homeostasis from overload and/or injury produces pain. Bone overload and synovial inflammation are common sources of such pain. Chondromalacia and malalignment are findings that almost always do not need to be "corrected" to relieve pain. Patience and persistence in nonoperative care results in consistent success. Surgery should be rare and done only after extensive nonoperative management and in the setting of clearly defined pathology...

STUDY DESIGN: Retrospective chart review. OBJECTIVE: To determine the long-term efficacy of 2-stage total en bloc spondylectomy (TES). SUMMARY OF BACKGROUND DATA: TES is a well-described technique to achieve tumor-free margins, but it is a highly destabilizing procedure that necessitates spinal reconstruction. A 2-stage anterior/posterior approach for tumor resection and instrumentation has been shown to be biomechanically superior to the single-stage approach in achieving rigid fixation, but few clinical studies with long-term outcomes exist...

OBJECTIVE: The aim of the current study was to assess symptomatic outcome and need for surgical reintervention for patients identified with pathological esophageal acid exposure by routine postoperative 24-hour pH-monitoring. BACKGROUND: Although laparoscopic fundoplication is associated with excellent short- and midterm results, recurrent symptoms pose an important challenge. Postoperative pH-monitoring is considered the "gold standard" for diagnosing recurrent GERD and frequently used for routine postoperative follow up...

BACKGROUND: The objective of surgical management of spinal metastases is to reduce pain and improve the patient's quality of life. The operation should restore spinal stability and decompress neural structures. One surgical technique is corpectomy followed by vertebral body reconstruction and stabilisation of the spine. The procedure may be performed in patients in overall good health and a good survival prognosis. The aim of this paper is to present the outcomes of surgical management of spinal metastases in patients who underwent corpectomy followed by vertebral body reconstruction and stabilisation of the spine...

INTRODUCTION: Evidence has demonstrated that tumor size is related to adverse oncologic outcomes in small renal tumors (≤ 4 cm). We evaluated the association of adverse pathologic features (APF) with tumor size and survival in patients with a small renal mass (SRM). MATERIALS AND METHODS: We retrospectively reviewed the pathologic characteristics of 380 surgically resected SRMs from a single institution. APFs included lymphovascular invasion, coagulative necrosis, sarcomatoid/rhabdoid features, papillary type II histology, and perinephric fat/renal sinus invasion...

REVIEW
Jessica Figueroa, John G DeVine
Review the current literature regarding spontaneous spinal epidural hematomas (SSEHs) and report on the known risk factors, evaluation, and treatment of this rare entity. A literature search was performed using PubMed and Ovid to identify articles pertaining to SSEHs. Due to the rarity of the pathologic entity, only scattered case reports and associated reviews are available. SSEHs are a rare yet potentially life-altering event. The underlying risk factors are poorly understood, and SSEHs present with minimal or no antecedent trauma...

Primary cardiac malignancies are rare entities. Although sarcomas enclosed the main group of malignant heart neoplasms, primary cardiac leiomyosarcomas are extremely rare and constitutes less than 8% of cardiac tumors. Leiomyosarcoma usually originates from the pulmonary veins and have a worm-like shaped structure. In this article, we present a case of a 40-year-old Hispanic man diagnosed with a cardiac tumor who underwent surgical resection, during pathological examination the tissue samples were consistent with a malignancy of mesenchymal origin that contained irregular bundles of spindle cells...

Primary papillary tumors of the pineal region (PTPR) are rare entities with distinct histopathological characteristics. Most common surgical approaches include the supra-cerebellar infratentorial corridor or the occipital interhemispheric approach. Gamma knife radiosurgery (GKRS) is an acceptable treatment modality for parenchymal tumors of the pineal gland, and often used as a primary treatment modality for asymptomatic and indolent lesions, and as an adjunct to surgical resection. In this presentation, we describe the surgical nuances of posterior interhemispheric approach in an elderly male with a previously failed empirical GKRS...

Small invasion into ductal carcinoma in situ (DCIS) can easily be overlooked in resected breast specimens. To disclose useful markers predictive of invasive foci within preoperatively diagnosed DCIS lesions, a retrospective histopathological comparison was made between postoperatively diagnosed invasive ductal carcinoma with a predominant intraductal component (IDCPIC) (n=43) and pure DCIS (n=82). Through a multivariate logistic regression analysis model, 5 variables (DCIS grade, "tumor thickness", extent of retraction cleft, presence of lymph node metastasis, and HER2 score) were found to be significantly associated with the presence of invasive foci within DCIS; with a cutoff point of 0...

Despite remarkable progress in imaging modalities and surgical management, persistence or recurrence of primary hyperparathyroidism (PHPT) still occurs in 2.5-5% of cases of PHPT. The aim of this review is to expose the management of persistent and recurrent hyperparathyroidism. A literature search was performed on MEDLINE using the search terms "recurrent" or "persistent" and "hyperparathyroidism" within the past 10 years. We also searched the reference lists of articles identified by this search strategy and selected those we judged relevant...
