BACKGROUND: The profile and management of self-inflicted abdominal stab wounds (SI-ASW) patients is still obscure. METHODS: The National Trauma Data Bank (2012) was queried for adults with abdominal stab wounds (n = 9544). Patients with SI-ASW (n = 1724) and non-SI-ASW (n = 7820) were compared. Predictors for non-therapeutic laparotomy/laparoscopy (non-TL) in SI-ASW patients were identified. RESULTS: SI-ASW patients were older, had more females and behavioral disorders, similar physiology, but a lower Injury Severity Score...

OBJECTIVE: The aim of the present study was to compare the outcomes of conservative versus surgical treatment for acute appendicitis. BACKGROUND: Although acute appendicitis is a common disease, great debate exists regarding the appropriate management of patients. Conservative treatment has shown positive results in several RCTs, eliciting questions about indications to surgery, therapeutic appropriateness and ethical conduct. METHODS: Data were prospectively collected; a Propensity Score-based matching method was implemented in order to reduce bias arising from characteristics of the patients; a proportion of patients (69 in total) were excluded to obtain two comparable groups of study (1a)...

BACKGROUND: Even though most patients who undergo resection of pancreatic adenocarcinoma have T3 disease with extra-pancreatic tumor extension, T3 disease is not currently classified by tumor size. The aim of this study was to modify the current TNM classification of pancreatic adenocarcinoma to reflect the influence of tumor size. METHODS: A total of 847 consecutive pancreatectomy patients were recruited from multiple centers. Optimum tumor size cutoff values were calculated by receiver operating characteristics analysis for tumors limited to the pancreas (T1/2) and for T3 tumors...

BACKGROUND: Organ dysfunction is common after neurologic determination of death (NDD) but before organ collection. Reliable markers for graft success following transplant of these organs would be useful. We sought to determine the relationship between the donor after neurologic determination of death (DNDD) pathophysiology and successful organ donation. METHODS: Donor information was obtained through the local organ procurement organization. Donor demographics and clinical data points for cardiovascular, renal, respiratory, hepatic, hematological and neuroendocrine systems were reviewed 12 h before and 12 h after neurologic determination of death was declared...

BACKGROUND: Hidradenitis suppurativa is a painful and disfiguring chronic inflammatory condition affecting both men and women. Medical treatments, such as antibiotics and immunosuppressive agents, are often ineffective. Over time, patients can suffer from recurrent abscesses, chronic purulent drainage, scarring, and contractures that can only be corrected by surgical excision. There is no agreement, however, on the best way for the surgeon to manage this condition. The purpose of this review is to describe the results of surgical treatment of this condition in a large cohort of patients managed by local excision of hidradenitis, healing by secondary intention and reoperation as needed...

BACKGROUND: Platinum resistance enhances DNA damage repair through nucleotide excision repair mechanisms involving the excision repair cross-complementing group 1 (ERCC1), X-ray cross-complementing group 1 (XRCC1), and excision repair cross-complementing group 2 (ERCC2). We evaluated the correlation between the expression of these three DNA repair genes and clinical outcomes in patients with rectal cancer receiving FOLFOX-based preoperative chemoradiotherapy (CRT). METHODS: Using immunohistochemistry, we examined the expression of ERCC1, ERCC2, and XRCC1 in pre-CRT cancer tissues from 86 patients with rectal cancer who had undergone curative resection and preoperative CRT with FOLFOX-4 to identify potential predictors of clinical outcomes...

BACKGROUND: Pancreatic texture is one of the key predictors of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Currently, the "gold standard" for assessment of pancreatic texture is surgeon's subjective evaluation through manual palpation. AIM: To evaluate a new "durometer" that is able to assess quantitatively the pancreatic stiffness by measuring its elastic module (i.e., the resistance offered by the pancreatic stump when elastically deformed expressed in mPa)...
