A rare case of Amyand's hernia in a 67-year-old male. A case report and review of the literature.

AIM: The aim of the study is to indicate the Amyand's hernia as a possible complication during surgery for hernia repair performed in emergency CASE REPORT: A case Amyand's hernia complicated by the presence of acute gangrenous appendicitis perforated at the base is reported. DISCUSSION: Amyand's hernia is an hernia which is the vermiform appendix inside. This condition may remain asymptomatic and behave like a normal inguinal hernia or can simulate strangulated hernia when the hernia contains inflamed appendix. CONCLUSION: Acute appendicitis in an incarcerated inguinal hernia is a rare event. The preoperative diagnosis is very difficult because it simulates the behavior of a strangulated inguinal hernia. The treatment depends on the severity of appendicitis. The appendicitis status influences the type of surgery and the type of access.

The measurement of amylase in drain fluid for the detection of pancreatic fistula after gastric cancer surgery: an interim analysis.

BACKGROUND: Pancreatic fistula is still one of the most serious and potential complications after D2-D3 distal and total gastrectomy (4% to 6%). Despite their importance, pancreatic fistulas still have not been uniformly defined. Amylase concentration of the drainage fluid after surgery for gastric cancer can be considered as a predictive factor of the presence of pancreatic fistula. METHODS: From January 2009 to April 2013, 53 patients underwent surgery for gastric cancer. Amylase concentration in the drainage fluid was measured on the first postoperative day and if it was ≥1,000 UI, it was measured again on the third postoperative day. Pancreatic fistula occurred in four cases (7.5%). Pancreatic fistulas were classified using the International Study Group on Pancreatic Fistula (ISGPF) criteria into different grades of severity. Two fistulas were Grade A, one was Grade B, and one was Grade C. RESULTS: Management of drainage tubes is still crucial after gastrectomy, not only for the likelihood of anastomotic leaks but also the eventual diagnosis and management of pancreatic fistula. High amylase drainage content and then the presence of the pancreatic fistula may be due to several causes: the operation itself when it includes splenectomy or pancreatic tail-splenectomy, the extended lymphadenectomy but even the 'gently and softly' pancreatic manipulation, according literature, may be a risk factor. CONCLUSIONS: The authors assessed amylase concentration in the drainage fluid collected from the left subphrenic cavity on POD1 and POD3 in 53 patients who had undergone curative gastrectomy for cancer and concluded that amylase drainage content >3 times the serum amylase was a useful predictive risk factor for pancreatic fistula. Our work is an interim analysis and the aim of this study is to increase the accrual of the number of patients to have a significant number. For this reason, a protocol for a multicenter trial will be designed to verify whether the systematic measurement of amylase in drain fluid is better than abdominal ultrasound for the detection of pancreatic fistula after gastric cancer surgery.

Breast cancer micrometastasis and axillary sentinel lymph nodes frozen section. Our experience and review of literature.

BACKGROUND: Sentinel lymph node (SLN) biopsy plays a major role in the surgical management of primary breast cancer. The aim of this study was to assess the diagnostic accuracy of the assessment of axillary frozen sections of SLNs for micrometastasis diagnosis. PATIENTS AND METHODS: This study focused on 250 SLNs from 137 patients. Each lymph node was fully analyzed by frozen section. After fixation, serial sections were cut and stained by hematoxylin and eosin (HE) and for pan-cytokeratins by immunohistochemistry (IHC). RESULTS: Tumor cells were detected in 57 SLNs, 37 on frozen sections and 20 on controls. Of these 57 positive SLNs, 38 contained metastases, 9 contained micrometastases and 10 contained isolated tumor cells. The specificity and positive predictive value of SLN frozen sections for micrometastasis was 100%. The sensitivity was 83.3% for metastasis, 40% for micrometastasis; the false-negative rate was 16.7% for metastasis and 60% for micrometastasis. CONCLUSION: Analysis of frozen section of SLNs is an accurate method for metastasis detection, allowing concurrent axillary dissection when positive. The protocol for SLN analyses described herein shows good sensitivity for micrometastasis detection.

Requirement for a standardised definition of advanced gastric cancer.

Each year, ~988,000 new cases of stomach cancer are reported worldwide. Uniformity for the definition of advanced gastric cancer (AGC) is required to ensure the improved management of patients. Various classifications do actually exist for gastric cancer, but the classification determined by lesion depth is extremely important, as it has been shown to correlate with patient prognosis; for example, early gastric cancer (EGC) has a favourable prognosis when compared with AGC. In the literature, the definition of EGC is clear, however, there is heterogeneity in the definition of AGC. In the current study, all parameters of the TNM classification for AGC reported in each previous study were individually analysed. It was necessary to perform a comprehensive systematic literature search of all previous studies that have reported a definition of ACG to guarantee homogeneity in the assessment of surgical outcome. It must be understood that the term 'advanced gastric cancer' may implicate a number of stages of disease, and studies must highlight the exact clinical TNM stages used for evaluation of the study.

Synchronous colorectal neoplasias: our experience about laparoscopic-TEM combined treatment.

Synchronous colorectal neoplasias are defined as 2 or more primary tumors identified in the same patient and at the same time. The most voluminous synchronous cancer is called "first primitive" or "index" cancer. The aim of this work is to describe our experience of minimally invasive approach in patients with synchronous colorectal neoplasias.Since January 2001 till December 2009, 557 patients underwent colectomy for colorectal cancer at the Department of General and Emergency Surgery of the University of Perugia; 128 were right colon cancers, 195 were left colon cancers while 234 patients were affected by rectal cancers. We performed 224 laparoscopic colectomies (112 right, 67 left colectomies and 45 anterior resections of rectum), 91 Transanal Endoscopic Microsurgical Excisions (TEM) and 53 Trans Anal Excisions (TAE). In the same observation period 6 patients, 4 males and 2 females, were diagnosed with synchronous colorectal neoplasias. Minimal invasive treatment of colorectal cancer offers the opportunity to treat two different neoplastic lesions at the same time, with a shorter post-operative hospitalization and minor complications. According to our experience, laparoscopy and TEM may ease the treatment of synchronous diseases with a lower morbidity rate.

A severe case of hemobilia and biliary fistula following an open urgent cholecystectomy.

BACKGROUND: Cholecystectomy has been the treatment of choice for symptomatic gallstones, but remains the greatest source of post-operative biliary injuries. Laparoscopic approach has been recently preferred because of short hospitalisation and low morbidity but has an higher incidence of biliary leakages and bile duct injuries than open one due to a technical error or misinterpretation of the anatomy. Even open cholecystectomy presents a small number of complications especially if it was performed in urgency. Hemobilia is one of the most common cause of upper gastrointestinal bleeding from the biliary ducts into the gastrointestinal tract due to trauma, advent of invasive procedures such as percutaneous liver biopsy, transhepatic cholangiography, and biliary drainage. METHODS: We report here a case of massive hemobilia in a 60-year-old man who underwent an urgent open cholecystectomy and a subsequent placement of a transhepatic biliary drainage. CONCLUSION: The management of these complications enclose endoscopic, percutaneous and surgical therapies. After a diagnosis of biliary fistula, it's most important to assess the adequacy of bile drainage to determine a controlled fistula and to avoid bile collection and peritonitis. Transarterial embolization is the first line of intervention to stop hemobilia while surgical intervention should be considered if embolization fails or is contraindicated.
