Surgical Unit volume and 30-day reoperation rate following primary resection for colorectal cancer in the Veneto Region (Italy).

BACKGROUND: The aim of this study was to evaluate the impact of Surgical Unit volume on the 30-day reoperation rate in patients with CRC. METHODS: Data were extracted from the regional Hospital Discharge Dataset and included patients who underwent elective resection for primary CRC in the Veneto Region (2005-2013). The primary outcome measure was any unplanned reoperation performed within 30 days from the index surgery. Independent variables were: age, gender, comorbidity, previous abdominal surgery, site and year of the resection, open/laparoscopic approach and yearly Surgical Unit volume for colorectal resections as a whole, and in detail for colonic, rectal and laparoscopic resections. Multilevel multivariate regression analysis was used to evaluate the impact of variables on the outcome measure. RESULTS: During the study period, 21,797 elective primary colorectal resections were performed. The 30-day reoperation rate was 5.5% and was not associated with Surgical Unit volume. In multivariate multilevel analysis, a statistically significant association was found between 30-day reoperation rate and rectal resection volume (intermediate-volume group OR 0.75; 95% CI 0.56-0.99) and laparoscopic approach (high-volume group OR 0.69; 95% CI 0.51-0.96). CONCLUSIONS: While Surgical Unit volume is not a predictor of 30-day reoperation after CRC resection, it is associated with an early return to the operating room for patients operated on for rectal cancer or with a laparoscopic approach. These findings suggest that quality improvement programmes or centralization of surgery may only be required for subgroups of CRC patients.

[Inguinal endometriosis. Case report and review of the literature]. / L'endometriosi inguinale. Case report e revisione della letteratura.

Endometriosis is a common gynaecological condition which affects women during their reproductive years. It is characterized by ectopic endometrial tissue responding to hormonal changes associated with menstrual cycle. Aetiology is unknown and symptoms are quite aspecific (dysmenorrhoea, pelvic pain, infertility or pelvic mass). Ultrasonography (US) and Magnetic Resonance Imaging (MRI) are accurate diagnostic exams but laparoscopy represents the gold standard in diagnosis and therapy (excision or ablation). Medical treatment pre or postoperatively may be useful prolonging the symptom free interval. In this paper we report the case of a young woman affected by an inguinal mass: diagnostic examinations and histological specimen revealed to be an endometrial focus. We review the literature focusing the diagnostic techniques and relationships between endometriosis and ovarian cancer (endometrioid and clear cell subtypes).

[Mesenteric cyst: case report and review of the literature]. / Cisti mesenteriale: case report e revisione della letteratura.

Mesenteric and retroperitoneal cysts are rare intra-abdominal tumours with an incidence of 1/140.000 in surgery departments and 1/20.000 in paediatric departments. There are no pathognomonic signs or symptoms for the cysts. In the differential diagnosis lymphangiomas, sarcomas, adenocarcinomas and intestinal duplications should be considered. Diagnostic includes abdominal computed tomography, ultrasound and MRI. Barium enema examination or intravenous pyelogram may be used in special cases. Surgical treatment is indicated also in asymptomatic patients; laparoscopic approach is the "gold standard". Laparotomic approach should be used in the cases of impossibility of total enucleation or in the cases of malignant degeneration. Complete enucleation is the treatment of choice for retroperitoneal and mesenteric cysts. If this cannot be accomplished, the alternative should be the excision of the cyst or the marsupialization. In this paper we present a case of young man with a mesenteric cyst mimicking acute appendicitis.

Disaster coordination and management: summary and action plans.

INTRODUCTION: Disaster is a collective responsibility requiring coordinated response from all parts of society. This theme focused on coordination and management issues in a diverse range of scenarios. METHODS: Details of the methods used are provided in the preceding paper. The chairs moderated all presentations and produced a summary that was presented to an assembly of all of the delegates. Although the main points developed in Themes 1 and 4 were different from each other (as reported in the Results section), their implementation was similar. Therefore, the chairs of both groups presided over one workshop that resulted in the generation of a set of Action Plans that then were reported to the collective group of all delegates. RESULTS: The main points developed during the presentations and discussions included: (1) the need for evidence-based assessments and planning, (2) the need for a shift in focus to health-sector readiness, (3) empowerment of survivors, (4) provision of relief for the caregivers, (5) address the incentives and disincentives to attain readiness, (6) engage in joint preparation, response, and training, (7) focus on prevention and mitigation of the damage from events, and (8) improve media relations. There exists a need for institutionalization of processes for learning from experiences obtained from disasters. DISCUSSION: Action plans presented include: (1) creation of an Information and Data Clearinghouse on Disaster Management, (2) identification of incentives and disincentives for readiness and develop strategies and interventions, and (3) act on lessons learned from evidence-based research and practical experience. CONCLUSIONS: There is an urgent need to proactively establish coordination and management procedures in advance of any crisis. A number of important insights for improvement in coordination and management during disasters emerged.

Congenital choledochal cyst: video-guided laparoscopic treatment.

We report our first experience with a laparoscopic treatment of congenital choledochal cysts involving the total cyst resection and the reconstruction of the biliary and gastrointestinal tracts through a transmesocolic hepatic-jejunal Roux-en-Y loop anastomosis. The procedure was carried out in a 14-kg 6-year-old girl with a congenital choledochal cyst of the first type, according to the Alonso-Lej classification. The cyst was divided using a Multifire EndoGIA 30 stapler. Hepatic-jejunal and jejunojejunal anastomoses were made with 4.0 chrome catgut interrupted sutures. Intestinal recanalization occurred on the 2nd postoperative day and the postoperative course was uneventful. The laparoscopic approach affords several advantages: excellent intraoperative visualization of tiny structures and, therefore, great surgical accuracy; early resumption of peristalsis; no postoperative pain; no laparocele; prevention of adhesions; excellent esthetics; and quicker resumption of school and sports activities.

[Laparoscopic cholecystectomy for gallbladder stones]. / Trattamento della calcolosi colecistica con colecistectomia laparoscopica.

The authors describe the technique for the treatment of gallbladder stones using a laparoscopic approach and discuss the diagnostic and operative flow chart stressing complications and ways to avoid them. A total of 2517 non-selected patients underwent surgery since october 1990 up to september 1995. 252 were affected by acute cholecystitis (10%); 172 underwent emergency laparoscopic cholecystectomy. ERCP was performed in 278 patients (11.04%): 177 underwent endoscopic sphincterotomy and laparoscopic cholecystectomy, 21 underwent laparoscopic cholecystectomy before sphincterotomy, 8 laparoscopic cholecystectomy and ESWL. Laparoscopic cholecystectomy was converted into laparotomy in 37 patients (1.4%); surgery was abandoned in 3 patients following to onset of intense bradycardia. Major complications were observed in 0.63%; bile duct injury occurred in four patients (0.15%). One patient died following a massive intraoperative myocardial infarction. Average operative time was 21 minutes. Only 22.8% of patients required mild analgesia on the first day after surgery. The average hospital postoperative stay was 2.6 days. Return to work took place in 98% of non complicated patients within one week of being discharged from hospital.

[Choledochoduodenal anastomosis by laparoscopy]. / L'anastomose cholédoco-duodénale par voie laparoscopique.

Eleven patients underwent choledochoduodenostomy under laparoscopic control: 5 for adenocarcinoma of head of pancreas, including 2 with extension into duodenum, 3 for chronic pancreatitis. 1 for gastric carcinoma with pancreatic infiltration 1 for carcinoma of ampulla and 1 for stenosing papillitis. Mean duration of operation was 97.9 minutes and mean hospital stay 7.8 days. No immediate or delayed postoperative complications were reported. The advantages of this method are the marked reduction in recovery time, especially in severely debilitated elderly patients, and the absence of postoperative pain.

[Laparoscopic cholecystectomy using argon bistoury]. / La colecistectomia laparoscopica con il bisturi ad Argon.

A total of 92 patients were submitted to laparoscopic cholecystectomy during the period Autumn 1990-Spring 1991. The dissection of the gallbladder from the hepatic bed was performed in 40 patients using the Argon beam coagulator, in 25 using the monopolar electrocoagulator and in 27 using the Holmio laser beam. In average, with the Argon beam coagulator time procedure was respectively 2.7 and 5.4 minutes shorter than monopolar electrocoagulator and Holmio laser. Only one complication (pneumomediastinum) was correlated with the use of the Argon beam coagulator.

[Cardiac failure due to isolated pulmonary sequestration. Description of a clinical case in the neonatal period]. / Scompenso cardiaco da sequestro polmonare isolato. Descrizione di un caso clinico in età neonatale.

Pulmonary Sequestration is a congenital anomaly rarely seen in the pediatric age. Clinical manifestations commonly appear with a respiratory symptomatology and less frequently with cardiac signs especially in the case of an associated congenital heart disease. In the presented case, isolated Pulmonary Sequestration manifested itself as a congestive heart failure, and a diastolic overloading of the left ventricle. After surgical removal of the Sequestration was demonstrated a normalization of both clinical and haemodynamic findings.

[Surgical treatment of isthmic coarctation of the aorta by left subclavian artery post-isthmic aortic by-pass]. / Trattamento chirurgico della coartazione istmica dell'aorta mediante by-pass tra arteria succlavia sinistra e aorta post-istmica.

Between May 1978 and July 1981 at the Department of Cardiovascular Surgery, Padua University Medical School in Verona, 10 patients with coarctation of the aorta underwent surgical treatment with a by-pass between the left subclavian artery and the descending aorta. A synthetic fibre graft was employed. The patient's age varied between 20 and 46 years and all were hypertensive: 160-220 mmHg systolic, 90-110 diastolic pressure. No hospital deaths occurred. Blood pressure decreased significantly in all patients as well as their electrocardiographic signs of left ventricular hypertrophy.
