Cytopathologic diagnosis of fine needle aspiration biopsies of thyroid nodules

Fine-needle aspiration(FNA) cytology is an important diagnostic tool in patients with thyroid lesions.Several systems have been proposed for the cyropathologic diagnosis of the thyroid nodules.However cases with indeterminate cytological findings still remain a matter of debate.In this review we analyze all literature regarding Thyroid Cytopathology Reporting systems trying to identify the most suitable methodology to use in clinical practice for the preoperative diagnosis of thyroid nodules.A review of the English literature was conducted,and data were analyzed and summarized and integrated from the authors' perspective.The main purpose of thyroid FNA is to identify patients with higher risk for malignancy,and to prevent unnecessary surgeries for benign conditions.The Bethesda System for Reporting Thyroid Cytopathology is the most widely used system for the diagnosis of thyroid FNA specimens.This system also contains guidelines for the diagnosis and treatment of indeterminate or suspicious for malignancy cases.In conclusion,patients who require repeated FNAs for indeterminate diagnoses will be resolved by repeat FNA in a percentage of 72%-80%.

Laparoscopic splenectomy:Current concepts

Since early 1990's,when it was inaugurally introduced,laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications.Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen.However some contraindications still apply.The evolution of the technology has allowed though,cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches.Moreover,the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications.Today,laparoscopic splenectomy is considered safe,with better outcomes in comparison to open splenectomy,and the increased experience of surgeons allows operative times comparable to those of an open splenectomy.In this review we discuss the indications and the contraindications of laparoscopic splenectomy.Moreover we analyze the standard and modified surgical approaches,and we evaluate the short-term and long-term outcomes.

结肠的腺癌和麦芽淋巴瘤的同时的出现: 一系列三个盒子

Simultaneous development of adenocarcinoma and primary B cell lymphoma of mucosa-associated lymphoid tissue(MALT) lymphoma of the colon is rare;only one case has so far been reported out of 13 cases with the coexistence of colonic adenocarcinoma with involvement of the colon by lymphoma.We hereby present three more cases,two females(aged 75 and 71 years) and a male(aged 72 years).All three underwent colectomy based on a preoperative biopsy revealing colonic carcinoma.Histological examination of the resection specimens disclosed a colonic adenocarcinoma in two cases,whereas a tubulovillous adenoma with superficial foci of intraepithelial adenocarcinoma was seen in the thirdcase.Moreover,in all three cases,a coexisting MALT lymphoma was diagnosed in the colon(1 case),in both colon and adjacent lymph nodes(1 case) or in colonic lymph nodes and omentum(1 case).In the last case,a post-operative bone marrow biopsy revealed extensive infiltration of the bone marrow,due to which the patient received postoperative chemotherapy.Diagnostic and treatment issues are briefly discussed.

Improvement of gastric emptying by enhanced recovery after pancreaticoduodenectomy

BACKGROUND： Enhanced recovery after surgery（ERAS） has improved postoperative outcomes particularly in colorectal surgery. This study aimed to assess compliance with an ERAS protocol and evaluate its effect on postoperative outcomes in patients undergoing pancreaticoduodenectomy. METHODS： Fifty patients who had received conventional peri operative management from 2005 to 2009（conventional group）were compared with 75 patients who had received perioperative care with an ERAS protocol（fast-track group） from 2010 to2014. Mortality, complications, readmissions and length of hospital stay were evaluated and compared in the groups.RESULTS： Compliance with each element of the ERAS pro tocol ranged from 74.7% to 100%. Uneventful patients had a significant higher adherence to the ERAS protocol（87.5% vs40.7%; P〈0.001）. There were no significant differences in de mographics and perioperative characteristics between the two groups. Patients in the fast-track group had a shorter time to remove the nasogastric tube, start liquid diet and solid food pass flatus and stools, and remove drains. No difference was found in mortality, relaparotomy, readmission rates and over all morbidity. However, delayed gastric emptying and length of hospital stay were significantly reduced in the fast-track group. The independent effect of the ERAS protocol in reduc ing delayed gastric emptying and length of hospital stay was confirmed by multivariate analysis.CONCLUSION： ERAS pathway was feasible and safe in improving gastric emptying, yielding an earlier postoperative recovery, and reducing the length of hospital stay.

Current Trends in the Management of Inguinal Hernia in Children

Inguinal hernia repairs in one of the most common surgical procedures in the pediatric population. Its diagnosis is made easily and the repair is usually performed by open surgery and with low complications rates. However, a substantial number of topics concerning anesthetic management, the precise time of operation especially in premature and high-risk infants, and the need of contralateral exploration have not yet been resolved. Recently, the introduction of laparoscopic repair seems to play a significant role regarding the safety, the examination and possible simultaneously repair of the contralateral groin, and the better cosmetic results. In this review, the current trends of the above mentioned topics will be discussed.
