Purpose

Postoperative superficial surgical site infection is a major complication in hepatobiliary-pancreatic surgery. We aimed to compare the efficacy of subcuticular sutures versus staples for skin closure in preventing superficial surgical site infection in hepatobiliary-pancreatic surgery.

Methods

Consecutive patients who underwent hepatobiliary-pancreatic surgery at our hospital from October 2006 to March 2011 and from April 2012 to March 2015 were reviewed retrospectively. Superficial surgical site infection incidence was evaluated in patients who received subcuticular sutures and those who received staples for skin closure. Propensity score matching analysis was used to adjust bias from confounding factors.

Results

A total of 691 patients were included. Patients with skin staple closures (n?=?346) were compared with patients with subcuticular suture closures (n?=?345). After a propensity score matching analysis, a significant difference in superficial surgical site infection incidence was found between the skin stapler group (11.3%) and subcuticular sutures group (2.6%). The same comparison was performed by a subgroup analysis and supported this finding in patients after hepatectomy without biliary reconstruction, pancreatoduodenectomy, or open laparotomy surgeries and in patients with body mass index <?25.

Conclusions

Subcuticular suturing after hepatobiliary-pancreatic surgery was more efficacious in reducing postoperative superficial surgical site infection incidence than staples for skin closure.

Several characteristics of neointimal tissues, including neoatherosclerotic progression, have been reported in lesions with in-stent restenosis (ISR). However, the effects of these characteristics on outcomes after percutaneous coronary intervention (PCI) for ISR lesions remain unclear. We assessed the relationships between neointimal tissue characteristics and the occurrence of periprocedural myonecrosis (PMN) after PCI in ISR lesions. We investigated 72 ISR lesions in 72 patients with stable angina pectoris (SAP) who underwent pre- and post-revascularization optical coherence tomography (OCT) and coronary angioscopy (CAS). All lesions were classified as with PMN, defined by an elevated peak high-sensitivity cardiac troponin-T level during the 24-h post-PCI period, and without PMN. PMN was observed in 23 (31.9?%) lesions. PMN lesions had higher frequencies of OCT-derived thin-cap fibroatheroma (26.1 vs. 6.1?%, P?=?0.03), CAS-derived intensive yellow neointima (30.4 vs. 10.2?%, P?=?0.04), neointima with complex surface (60.9 vs. 28.6?%, P?=?0.01), and CAS-derived atheromatous appearance (CAS-AAP), defined as yellow plaque including complex thrombi underneath disrupted neointimal coverage after ballooning (47.8 vs. 16.3?%, P?=?0.008) at the most stenotic sites inside stents, compared to lesions without PMN. Multivariate logistic regression analysis identified CAS-AAP (odds ratio: 3.568, 95?% confidence interval: 1.109–11.475, P?=?0.033) as an independent predictor of PMN. For ISR lesions in SAP patients, an OCT- and CAS-based assessment of neointimal tissue characteristics might help to predict the occurrence of PMN.  相似文献

We report herein a rare case of gastrointestinal stromal tumor (GIST) type, arising from the greater omentum. A 65-year-old man who had a large abdominal tumor was referred to our hospital. Ultrasonography (US) and computed tomography (CT) scans showed a mass occupying almost the entire abdomen anterior to the bowel loops. Abdominal angiography showed that the main feeding artery of the tumor was the right gastroepiploic artery. The preoperative diagnosis was suspected gastric leiomyosarcoma. Laparotomy revealed a large mass arising from the greater omentum, and the tumor seemed to be completely excised. Histopathological and immunohistochemical studies indicated the tumor had the same characteristics as GIST. Twelve months after the operation, the tumor recurred in the peritoneal cavity at the site of the stomach, and was associated with multiple liver metastases. The patient died of hypovolemic shock. Necropsy revealed that rupture of one of the metastatic liver tumors had resulted in a massive intraperitoneal hemorrhage.  相似文献

BACKGROUND: The current study aimed to investigate the effect of ablation therapy on the quality of life (QOL) in patients with atrial fibrillation (AF) by using a questionnaire specific for AF. METHODS AND RESULTS: A total of 86 patients (paroxysmal/chronic, 61/25) with drug-resistant AF undergoing extensive pulmonary vein isolation were recruited for the study. The QOL was quantitatively assessed by the Atrial Fibrillation Quality of Life Questionnaire at baseline, and 1, 3 and 6 months after the ablation. Sinus rhythm was maintained in 48/61 (79%) of the paroxysmal AF group, and 15/25 (60%) of those in the chronic AF group during 6 months after the initial ablation procedure. Among the patients without any AF recurrences, patients with chronic AF exhibited a substantial improvement in the QOL at 1 month after the procedure, and it remained unchanged until the end of the follow-up period. However, in the patients with paroxysmal AF, the QOL level gradually increased over a 6-month period. The patients with recurrent AF exhibited no improvement in the QOL. CONCLUSION: Although the clinical course of the QOL improvement was different, both paroxysmal and chronic AF patients gained better QOL to maintain sinus rhythm by means of catheter ablation.  相似文献
