Is there a relationship between length of resection and lymph-node ratio in colorectal cancer?

Background: The prognosis of colorectal cancer depends on the number of positive lymph nodes (LN+) and the total number of lymph nodes resected (rLN). This represents the lymph-node ratio (LNR). The aim of our study is to assess how the length of the resected specimen (RL) influences the prognostic values of the LNR.

The role of E-cadherin expression in the treatment of western undifferentiated early gastric cancer: Can a biological factor predict lymph node metastasis?

The use of endoscopic techniques to cure small sized, well differentiated early gastric cancer has been adopted worldwide. In the Eastern world, endoscopic resection is being increasingly utilized to treat small undifferentiated early gastric cancer according to the extended criteria proposed by the Japanese Gastric Cancer Associations. However, studies in the Western world reported in these tumors a rate of nodal metastasis ranging between 5% and 20%, that is higher of those observed in Eastern counterparts.

Gastric GIST and prognostic models. Which is the best to predict survival after surgery?

Background: Gastrointestinal Stromal Tumours (GIST) are the most frequent mesenchymal tumour of the alimentary tract. Their prognosis is largely variable as are their size, mitotic rate and site, the stomach being mostly affected. Several risk classifications have been proposed: two developed by the NIH, one proposed by the AFIP and one presented by the AJCC in 2010.

Laparoscopic repair of incisional hernia. Risk factors for the conversion.

Introduction: Some factors may affect the conversion to open of the laparoscopic treatment of incisional hernia. Their presence can help to choose the most appropriate technique identifying patients at high risk conversion.

Methods: A retrospective study has been performed on a cohort of 306 patients, selected among those undergone to elective laparoscopic surgery for post incisional hernia between 2005 and 2015.

Acellular dermal matrix for breast reconstruction after surgery for giant dermatofibrosarcoma protuberans.

Introduction: Dermatofibrosarcoma protuberans (DFSP) is a rare neoplasm that exceptionally can affect the breast, always originating from skin and dermis, so imposing large sacrifice of skin. Only few cases have been reported of intraparenchymal DFS. We describe a unique case of giant intraparenchymal DFS that required removal of all the gland and reconstructive surgery.

Total Thyroidectomy: the first, the best. The recurrent goiter issue.

Background: Redo surgery for recurrent goiter is still now, even in experienced hands, followed by higher morbidity than primary total thyroidectomy. Suppressive Levothyroxine therapy failed to improve the recurrence rate, while inducing a subclinical hyperthyroidism. Aim of this study is to verify morbidity after total thyroidectomy for benign thyroid diseases, both primary and after recurrence.

A pilot study about the oncologic safety of colonic self-expandable metal stents (SEMS) in obstructive colon cancer: is occlusion always better than "silent" perforation?

Objective: To evaluate the oncologic safety of colonic self-expandable metal stents (SEMS) in obstructive colon cancer.

Patients And Methods: We retrospectively reviewed all the patients who were treated with endoscopic placement of a self-expandable metallic stent (SEMS) at our institution.

Results: A total of 26 patients were identified during the study period, of which 24 patients (92.

Immunological reaction and oxidative stress after light or heavy polypropylene mesh implantation in inguinal hernioplasty: A CONSORT-prospective, randomized, clinical trial.

Unlabelled: The relationship between mesh weight and host tissue reaction has, so far, not been fully investigated. Lightweight meshes (LWM) are thought to give less inflammatory response compared with heavyweight meshes (HWM). The present study is a randomized, controlled, double-blind clinical trial performed in 61 patients who underwent an elective inguinal hernioplasty.

Laparoscopic cholecystectomy: ultrasonic energy versus monopolar electrosurgical energy.

Objective: Nowadays, laparoscopic cholecystectomy (LC) is undoubtedly considered the "gold standard" in the surgical treatment of symptomatic gallstones, gallbladder adenomas and acute cholecystitis. Among the alternative energy sources proposed (monopolar, bipolar electric scalpel, radiofrequency sealers) with the aim to dissect and/or seal, the ultrasonic energy has been frequently adopted, however without a widespread acceptance among surgeons for routine or emergency laparoscopic cholecystectomy. This study investigates the possible beneficial aspects of ultrasonic dissection and its efficacy in the closure of the cystic artery and duct.

Lymph node evaluation in gallbladder cancer: which role in the prognostic and therapeutic aspects. Update of the literature.

Objective: The widespread use of laparoscopy has changed the outcome of gallbladder cancer as a consequence of increasing referral and incidental discovering of earlier stages cancer. Nevertheless, GBC is still associated with a poor prognosis and lymphnodal involvement is a main prognostic factor, important both for staging and for evaluating surgery quality. No consensus exists about the extension of lymphadenectomy to be performed nor about contraindications to extensive resection.

Treatment of the pancreatic stump after DCP.

Objective: With improvement in methods, mortality after duodeno-cefalo pancreatectomy (DCP) has decreased to 5% even if complication rate is still high (30-50%). The pancreatic fistula still occurs in 25-50% of cases. Various methods of treating pancreatic stump have been proposed aimed to improve this rate.

The role of HIPEC in the treatment of peritoneal carcinomatosis from gastric cancer: between lights and shadows.

Gastric cancer is one of the most dreadful neoplastic diseases and remains the second cause of cancer death worldwide. Patients who develop peritoneal metastasis have a poor prognosis, with a median survival of less than 6 months. Despite being the cause of 60% of deaths from gastric cancer, peritoneal metastasis can still be considered a local disease and a local multidisciplinary approach can improve the prognosis even in this end-stage disease.

Managing the incidentally detected gallbladder cancer: algorithms and controversies.

Introduction: Gallbladder cancer (GBC) is the fifth most common neoplasm of the gastrointestinal tract and the most common cancer of the biliary tract. GBC is suspected preoperatively in only 30-40% of patients. The other 60-70% are discovered incidentally (IGBC) by the pathologist on a gallbladder specimen following cholecystectomy for benign diseases such as polyps, gallstones, and cholecystitis.

The safety of the Harmonic® FOCUS in open thyroidectomy: a prospective, randomized study comparing the Harmonic® FOCUS and traditional suture ligation (knot and tie) technique.

Since Kocher and Billroth refined an acceptable technique, the thyroidectomy has become one of the most frequent procedures in endocrine surgery and bilateral total thyroidectomy is performed in the majority of thyroid diseases. This work evaluated the use of the Harmonic(®) FOCUS and traditional suture ligation (knot and tie) technique in a prospective, randomized study of open thyroidectomy. Eighty two patients were randomized and divided into two similarly sized groups: the Harmonic(®) FOCUS group (F group) and traditional group (T group).

The role of 68-Ga-DOTATOC CT-PET in surgical tactic for gastric neuroendocrine tumors treatment: our experience: a case report.

Gastric neuroendocrine tumors (g-NETs), which originate from gastric enterochromaffin-like (ECL) mucosal cells and account for 2.4% of all carcinoids, are increasingly recognized due to expanding indications of upper gastrointestinal endoscopy. Often silent and benign, g-NETs may however, be aggressive and sometimes they mimic the course of gastric adenocarcinoma.

Staple line as a cause of unusual early internal hernia after appendectomy.

The use of mechanical stapling devices in laparoscopic appendectomies has become a common practice. Occasionally, the retained staples have been described to cause adhesions that might result in bowel obstruction. Early bowel obstruction after routine abdominal surgery should be closely investigated and might warrant early re-exploration.

Presentation and management of splenic injury after colonoscopy: a systematic review.

This study reviewed all single experience of splenic injuries after colonoscopy in the last 40 years to define the possible risk factors and the management of this complication. A MEDLINE and a PubMed search was undertaken to identify articles in English, French, Spanish, and Italian from 1974 to 2012 using the key words: "splenic injury," "splenic rupture," and "colonoscopy." Data were analyzed using descriptive statistic.

Pharmacokinetics of a new subcutaneous diclofenac formulation administered to three body sites: quadriceps, gluteus, and abdomen.

Objective: To assess the relative bioavailability of a new subcutaneous (SC) diclofenac hydroxypropyl b-cyclodextrin (HPbCD) formulation administered to three body sites: quadriceps, gluteus, and abdomen.

Materials And Methods: This was a pilot, single-dose, randomized, three-way crossover relative bioavailability study. A total of 12 healthy subjects received a single SC injection of diclofenac HPbCD 50 mg/1 mL in the quadriceps, gluteus, or abdomen.

Pharmacokinetic characterization of tizanidine nasal spray, a novel intranasal delivery method for the treatment of skeletal muscle spasm.

Background And Objective: The skeletal muscle relaxant tizanidine is approved by the US FDA and the European Medicines Agency for treating spasticity and is supplied as tablets for oral administration. However, tizanidine has a poor bioavailability, due to extensive first-pass metabolism. Therefore, the nasal route of administration, which bypasses portal circulation, may increase the bioavailability of tizanidine and, possibly, reduce the time to peak plasma concentration, thereby shorting the latency of therapeutic effect.

Giant gastrointestinal stromal tumor (GIST) of the stomach cause of high bowel obstruction: surgical management.

Background: Gastrointestinal stromal tumors (GISTs) represent 85% of all mesenchymal neoplasms that affect the gastrointestinal (GI) tract. These GISTs range in size from small lesions to large masses. Often they are clinically silent until they reach a significant size, so their discovery is usually incidental.

Surgical Site Infection by Corynebacterium macginleyi in a Patient with Neurofibromatosis Type 1.

Corynebacterium (C.) macginleyi is a gram positive, lipophilic rod, usually considered a colonizer of skin and mucosal surfaces. Several reports have associated C.

Abdominal wall reconstruction with intraperitoneal prosthesis in desmoid tumors surgery.

Desmoid tumor (DT), also known as aggressive fibromatosis, is a rare soft tissue neoplasm. For those tumors localized in the anterior abdominal wall, radical resection and reconstruction with mesh are indicated. Due to the rarity of this disease, there have been no randomized trials, but in reported retrospective series, although it is considered a benign lesion, it is clear that local recurrence is not uncommon.

[Venous thromboembolism prophylaxis after general surgery: where are we now?].

Venous thromboembolism (VTE) is a frequent complication in patients undergoing major surgery, with the possibility of long-term disability or fatal outcome. The rationale of the thromboprophylaxis in all patients can be summarized in three points: 1) the VTE is common in some types of surgery; 2) the VTE can be fatal; 3) thromboprophylaxis is highly effective and safe and, besides these clinical benefits, leads to lower total costs of treatment without further diagnostic and a new shelter for treating venous thrombosis. The surgical patients may present at admission one or more risk factors for VTE, The effect of this risk is cumulative, it is important to stratify the risk and to established an adequate prophylactic strategy.

Human pharmacokinetics of the muscle relaxant, eperisone hydrochloride by liquid chromatography-electrospray tandem mass spectrometry.

Eperisone hydrochloride (4'-ethyl-2-methyl-3-piperidinopropiophenone hydrochloride) is a muscle relaxant agent, widely used in the treatment of patients with muscular contractures, low back pain or spasticity. Because of its mechanism of action (inhibition of gamma-efferent firing and local vasodilatation activity), side effects on central nervous system are rarely observed. A sensitive liquid chromatography-electrospray ionization-mass spectrometry method for determination of eperisone in human plasma has been developed, with a lower limit of quantification of 0.
