The role of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of ovarian cancer relapse.

Nowadays the standard clinical management for advanced epithelial ovarian cancer is constituted by primary cytoreductive surgery associated to adjuvant systemic chemotherapy. Even if this first-line chemotherapy shows a high rate of complete responses, the disease recurrences occur especially in stage-III patients. Actually an option for this subset of patients is represented by secondary cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy that represents a promising therapy, having shown positive results in terms of median overall survival, progression free survival and overall survival. However, a much more research is still required especially by prospective randomised trials to improve outcomes in recurrent ovarian cancer.

Local repair of a trans-stomal ileocecal prolapse by stapler device.

The creation of a stoma, although considered a simple surgical procedure, is burdened by various complications, one of the most common being prolapse. Usually prolapse increases gradually, involving generally limited functional disorders and it can be well managed with non-operative measures. Occasionally it requires major surgery, for severe skin excoriation, bleeding or incarceration of the bowel. However, for critical clinical conditions of patients, often is not possible to use classical techniques, as bowel-pexy fixation or resection of the prolapse. Maeda has described a simple method for the correction of prolapse of the transverse colon using a stapler device that can be applied in this type of patients. In this report, we describe the first application of this technique to treat the prolapse of the ileocecal loop in an 81-year old woman, suffering from Parkinson's disease. A definitive ciecum stoma was performed the previous year for an Olgivie syndrome. At 6 months, follow-up showed no recurrence of prolapse with a functional stoma and without any skin irritation. In conclusion, this approach is recommended especially for high-risk patients who cannot be submitted to a much more invasive treatment. In fact, the main advantages consist of a minimally invasive technique, with minimal blood loss and with a rapid recovery of a normal quality of life.

Secondary cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for recurrent epithelial ovarian cancer: a multi-institutional study.

OBJECTIVE: To assess the efficacy and morbidity and mortality of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in recurrent epithelial ovarian cancer (EOC). DESIGN: A retrospective study conducted using information extracted from a multi-institutional prospective database on peritoneal surface malignancies (PSMs). Setting Four Italian centres specializing in locoregional treatment of PSM. POPULATION: Patients with recurrent EOC. METHODS: Fifty-six patients underwent 57 combined procedures. CRS was performed using peritonectomy procedures and HIPEC using the closed-abdomen technique with cisplatin and doxorubicin or cisplatin and mitomycin-C. MAIN OUTCOME MEASURES: Overall survival (OS), progression-free survival (PFS), morbidity and mortality rates. RESULTS: The median age of the patients was 55.2 years (range 30-75 years). The median peritoneal cancer index was 15.2 (range 4-30). Forty-seven patients had microscopic residual disease (completeness of cytoreduction, CC-0), seven had residual disease ≤2.5 mm (CC-1) and one had residual disease >2.5 mm (CC>2). Major complications occurred in 15 patients (26.3%), and procedure-related mortality occurred in three patients (5.3%). The median follow-up time was 23.1 months. The median OS and PFS were 25.7 (95% CI 20.3-31.0) and 10.8 (95% CI 5.4-16.2) months, respectively. The 5-year OS and PFS were 23% and 7%, respectively. Independent prognostic factors affecting OS according to the multivariate analysis were Eastern Cooperative Oncology Group performance status, preoperative serum albumin, and completeness of cytoreduction. CONCLUSIONS: Patients with recurrent EOC treated with CRS and HIPEC showed promising results in terms of outcome. The combined treatment strategy could benefit subsets of patients wider than that defined for conventional secondary debulking surgery without HIPEC. These data warrant further evaluation in randomised clinical trials.

[Intestinal perforation by ingested foreign bodies in the digestive tract: an insidious pathology always of interest. Our experience]. / La complicanza perforativa da ingestione di corpi estranei alimentari: una patologia insidiosa sempre attuale. Nostra esperienza.

The authors want to present five cases (from May 1999 to May 2009) of acute abdomen from perforation of the foreign body introduced with food. They highlight how the accidental ingestion is very common but the perforation is rare. The preoperative diagnosis, in these cases, is always very difficult and the radiological examinations are not always able to resolve the diagnostic doubt with other acute intestinal diseases that are responsible of perforation. Then, the surgery procedure is, necessarily, the only possible diagnostic and therapeutic means. The mortality and the morbidity remain still high first of all for the delay in the diagnosis and the advanced age of patients.

Massive bleeding from a Dieulafoy's lesion of the duodenum successfully treated with "adjuvant" transarterial embolization and endoscopic laser coagulation.

Dieulafoy's lesions, very rare in the duodenum, are considered uncommon causes of gastrointestinal bleeding and occur from pinpoint non-ulcerated arterial lesions. We report a case of Dieulafoy's lesion of the duodenum, in which a first diagnostic approach by using endoscopy and angiography was not successful; then, due to a high operative risk, we performed an "adjuvant" embolization of the gastroduodenal artery with the aim of reduce the flow through the artery, allowing the endoscopic localization of the site of bleeding and subsequent effective treatment. To our knowledge, this is the first case reported in the literature, in which, without aetiological diagnosis, an "adjuvant" embolization of the gastroduodenal artery was performed with the aim of reduce the blood flow in the duodenal wall, permitting an easier endoscopic diagnosis of Dieulafoy's duodenal lesion and successful treatment with laser coagulation.

Quintuple primitive malignant neoplasms. A case report.

The authors describe the case of a patient who developed during 31 months, five malignant tumours, three synchronous and two metachronous. The primitive origin and the long interval of time between the occurrence of each tumour, allow to set them in the group of Multiple Primitive Malignant Neoplasm. The authors, reviewing the classifications and the pathogenesis of these tumours, underline the importance of the follow-up in oncology patients and emphasize the role of nosographic setting in order to plan the most suitable therapeutic approach.

Evaluation of quality of life of patients submitted to cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal carcinosis of gastrointestinal and ovarian origin and identification of factors influencing outcome.

BACKGROUND: The prognosis of patients with peritoneal tumors has been improved by the association of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy, though still with an unclear impact on patients' quality of life. The purpose of our study was to evaluate the quality of life in 18 cases submitted to cytoreductive surgery and hyperthermic intraperitoneal chemotherapy and particularly to identify the factors that influence it. PATIENTS AND METHODS: Quality of life was evaluated using the functional assessment of cancer therapy; the results were correlated with 25 parameters. RESULTS: The study demonstrated that the patients'quality of life was not modified by treatment with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy; the dose of mitomycin C, the site of the primary tumor, gastrointestinal, renal and neurological toxicity, adjuvant chemotherapy, the patients' age and leukopenia were factors that influenced the quality of life. CONCLUSION: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy allows conservation of preoperative quality of life.

Hemorrhage from primitive rectal varices in patient with idiophatic thrombosis of portal vein: case report.

INTRODUCTION: Rectal varices, primitive or secondary to hypertensive or thrombotic disorders of mesenteric-portal circle, represent an uncommon cause of lower digestive bleeding. The presence of rectal varices associated to idiopathic venous portal thrombosis represents a distinct nosologic entity, with important clinical and therapeutic problems related to it. CASE REPORT: Patient of young age, with positive anamnesis for primitive rectal varices, admitted to our department for a serious recttorragy. The laboratory underlined moderate anaemia and the endoscopy documented the presence of multiple rectal varices, without evident signs of bleeding; the endoscopy documented the presence of two esophageal small varicose cords F1. The hepatobiliary sonography and the portography showed the massive thrombosis of the portal vein. The new serious episode of rectal bleeding induced us to subject the patient to a surgical operation of Hartmann recto-sigmoid resection. CONCLUSION: Because of the slight number of reported cases of primitive rectal varices and because of the scattering of many dates it is difficult to draw an univocal diagnostic and therapeutic algorithm. Clinical framing and subsequent therapeutic approach rise often up from personal experience rather than well defined guidelines. The treatment is controversial, time by time many therapeutic options are reported either conservative or interventionist. The failure of conservative therapy and the recurrent episodes of bleeding give indication to surgical treatment, that is represented by Hartmann colonic resection and/or the porto-systemic shunts in the cases of portal hypertension; in our case we made colonic resection sec. because of lapsed performing status of the patient.

Serum levels of interleukin 1beta, interleukin 8 and tumour necrosis factor alpha as markers of gastric cancer.

Despite the efforts made, a serum marker reliable for the screening and follow-up of patients with gastric cancer has not yet been identified. The aim of this preliminary study was to test the role of pro-inflammatory cytokines interleukin 1beta, interleukin 8 and tumour necrosis factor alpha in patients with gastric cancer and in control groups. The statistical analysis of cytokines serum levels in the group with gastric cancer versus control groups has shown considerable differences (p < 0.001) in their mean rates. The results indicate that the cytokines interleukin 1beta, interleukin 8 and tumour necrosis factor alpha might perhaps act as diagnostic markers in patients with gastric cancer. Therefore, it is hypothesized that after more extended trials, their use in the screening and prognostic assessment of these patients could be a possibility.

New model of liver regeneration induced through use of vascular endothelial growth factor.

INTRODUCTION: Vascular endothelial growth factor (VEGF) is an endothelial cell mitogen. The objective of this study was to verify the proregenerative effects of VEGF in an experimental model of acute liver failure. MATERIALS AND METHODS: Sixty four rats that underwent intraperitoneal injection of carbon tetrachloride (CCl(4)) were randomly divided into two groups: group B animals received intravenous injection of VEGF(164) 1 hour following CCl(4) poisoning. Group A hosts were untreated. To obtain daily liver function tests (LFTs) and histological samples, on each day up to 8 days we sacrificed four rats in each group. RESULTS: The laboratory examinations showed notable alteration of LFTs in group A, while group B revealed only slight changes. The histological examination showed greater liver damage in group A compared with group B. CONCLUSION: Our results suggest that administration of exogenous VEGF protects the liver from CCl(4)-induced acute hepatic failure. Further studies are underway to assess whether exogenous VEGF is effective in other liver injuries.

Acute gallstone cholecystitis in the elderly: treatment with emergency ultrasonographic percutaneous cholecystostomy and interval laparoscopic cholecystectomy.

BACKGROUND: The treatment of acute cholecystitis in the elderly is still a subject of debate, particularly with reference to the timing of surgery and the role of laparoscopy. PATIENTS: From January 1994 to June 2002 we observed 27 patients aged over 70 years with acute calcolous cholecystitis. The patients were submitted to ultrasonographic percutaneous cholecystostomy within 12 h of the acute attack. For two patients (7.4%) at high operative risk, we chose a conservative treatment. Twenty-five patients (92.6%) were submitted, in 15 cases (60%) within 5 days and in 10 patients (40%) within 8 days, to a laparoscopic cholecystectomy. Statistical significance was accepted when the value of p was less than 0.05. RESULTS: Ultrasonographic percutaneous cholecystostomy was performed successfully in all patients, without major morbidity or mortality, and complete resolution of clinical symptoms was obtained within 48 h. The conversion rate of laparoscopy was 20% (13.3% in patients submitted to surgery within 5 days and 30% in the group submitted within 8 days--p > 0.05). The postoperative morbidity rate was 24%; it was higher (40% versus 15%) in patients converted to laparotomy (p > 0.05); mortality was 4%. The period of hospitalization was 11 days in patients operated laparoscopically and 21 days in those converted to open cholecystectomy (p < 0.001). CONCLUSIONS: The more rational treatment of acute calcolous cholecystitis in elderly patients is represented by ultrasonographic percutaneous cholecystostomy followed, within 5 days, by laparoscopic cholecystectomy using an abdominal insufflation maximum to 12 mmHg and a limited 10-15 degrees head-up tilt.

[Diagnostic and therapeutic implications in two cases of pancreatic cystic tumours: mucinous and serous]. / Implicazioni diagnostiche e terapeutiche in due casi di tumori cistici del pancreas: mucinoso e sieroso.

Cystic tumours of the pancreas include a pathologically heterogeneous and rare group of tumours, which however have many common clinical features. They represent about 10% of pancreatic cystic lesions and 1% of all forms of neoplasms, thus having a certain relevance in organ surgery. So far two distinct categories of cystic tumours have been identified, the basically benign serous form and the potentially malign mucinous form, which may sometimes show malignant features as early as the diagnostic stage. As neoplasms are very difficult to interpret before operation, it is essential that diagnosis is as accurate as possible in order to streamline surgery, which will have to be carried out after histological tests have been performed on an adequate number of tumour sections. Basing on these two cases of cystic tumours of the pancreas and on current literature, the Authors discuss the effectiveness of imaging techniques, such as contrast echography, dosage of specific tumour markers and histological tests backed up by immunohistochemistry in identifying these neoplasms, in order to study this rare but interesting pathology more accurately.

Combined antegrade and retrograde ureteral stenting: the rendezvous technique.

Ureteral stenting is a routine procedure in endourology. To increase the success rate in difficult cases, it may be helpful to use the rendezvous technique, a combined antegrade and retrograde approach. We performed 16 urological rendezvous in 11 patients with ureteral strictures or urologic lesions. The combined approach was successful in all patients, without morbidity or mortality. In our experience the rendezvous technique increased the success rate of antegrade ureteral stenting from 78.6 to 88.09% (p > 0.05). This procedure is a valid option in case of failure of conventional ureteral stenting.

[Innovative use of the vascular endothelial growth factor in an experimental model of acute liver failure]. / Utilizzo innovativo del fattore di permeabilità vascolare in un modello sperimentale di insufficienza epatica acuta.

Vascular Endothelial Growth Factor (VEGF) is an endothelial cell mitogen and an important stimulator of sinusoidal endothelial cell proliferation. The aim of this research was to study the effects of exogenous VEGF in a rat model of acute liver failure. The study was conducted on 64 rats (240-300 g). All rats underwent intraperitoneal injection (5 ml/kg) of 25% carbon tetrachloride (CCl4) and 75% paraffin oil. This dosage of CCl4 was devised to induce nonfatal acute liver failure with spontaneous recovery in 7 days. The animals were randomly divided into 2 groups. Group B animals underwent i.v. injection of 200 ng of VEGF165 one hour following intra-peritoneal injection of CCl4. To obtain daily liver functional tests (LFTS) and histological liver samples, 4 rats in each group were sacrificed daily up to 8 days. In group A, the liver histology showed massive periportal hepatocyte necrosis associated with portal lymphocytic infiltrates. The peak of the damage was documented at 72 hours following CCl4. Group B showed minimal necrosis, moderate periportal edema and a minimum periportal steatosis. At 48 hours steatotic changes had disappeared and the periportal edema was resolving. LFTs demonstrated severe liver damage in rats in group A. In group A the peak AST (mean 322.5 IU/L) and ALT (mean 250.25 IU/L) were recorded at 72 hours. In group B, at 72 hours the mean AST was 137 IU/L (normal < 95 IU/L) and ALT 68 IU/L(normal < 45 IU/L). The maximum levels of AST and ALT, in group B, were 152.3 IU/L and 72.3 IU/L, at 24 hours. According to our results exogenous VEGF successfully protects the liver from CCl4 induced acute liver failure. Further studies will demonstrate if exogenous VEGF can be effective in other liver injuries.

[Hemorrhage and gastric perforation in patients with percutaneous endoscopic gastrostomy (PEG)]. / Emorragia e perforazione gastrica in paziente con gastrostomia endoscopica percutanea (PEG).

INTRODUCTION: PEG is more and more used for those patients who need a medium and above all long term enteral nutrition, especially at home. This is the closest technical system to the requirements to have an ideal nutritional access; however it is burdened, on average in 32.5% of cases, with complications linked to technical mistakes of positioning or to a wrong management, such as haemorrhage and gastric perforation. CASE REPORT: A patient, subjected to supraglottic laryngectomy, to removal of tongue's base and to bilateral laterocervical lymphadenectomy and PEG carrier for 4 months, has arrived to our observation for a clinical outline of acute abdomen for perforation of hollow internal organ, preceded by progressive anaemia due to high digestive haemorrhage. Performed an exploratory laparotomy, it was discovered on the gastric fore face, between body and antrum, in proximity to the small curvature and in front of the PEG gastric access, a perforation with max 2 cm of diameter, crossed by probe's internal disk of retention. They proceeded to remove that, to unstick the gastric stoma from the parietal peritoneum, to suture the access of gastrostomy and the perforation by omentoplasty. Finally they carried out a jejunostomy for enteral feeding. DISCUSSION: We think we can pathogenetically identify the cause of the haemorrhage and of the stomach's perforation, occurred in a short time in the case we have examined, in the probe's movement for incorrect fixing of the plate of external anchorage or for excessive slimming of the patient due to not balanced nutritional supply, as well as in the consequent extension of its intraluminal part with continuous rubbing by internal disk on the gastric wall and with onset decubitus ulcer. Physiopathologic moments, connected with the supposed etiological factor, make both occurred complications as an unique pathologic entity, which has to be observed in the PEG carriers, in order to be able to diagnose it and treat it precociously and above all in order to be able to prevent it. Only a correct technique of positioning and of nursing and of management of nutritional supply is able not to thwart the finality of the PEG device which can be considered, in the elective indications and for the favourable requisites that marks it, a valid access to enteral nutrition realization.

Pneumaturia in a patient with ectopic vas deferens opening in the bladder and agenesis of the ipsilateral seminal vesicle. Case report.

Ectopia of the vas deferens (EVD) combined with agenesis of the seminal vesicle, is a rare congenital abnormality. We describe a case of EVD with agenesis of the ipsilateral seminal vesicle, presenting with pneumaturia and frequent urinary tract infection.

Endoscopic clipping of a colocutaneous fistula following necrotizing pancreatitis: case report.

The case described here is of a 73-year-old male patient who developed a colocutaneous fistula following necrotizing pancreatitis, diagnosed by imaging and treated endoscopically by the application of an endoclip. Pancreatic and gastrointestinal fistulas, common complications of surgery for necrotizing pancreatitis, frequently require surgical treatment. Colonic perforations are the most difficult to treat surgically on account of the risk of peritonitis. A technique, namely, endoscopic clips application, has recently been developed to close anastomotic leakages and perforations of the oesophagus, stomach and colon. In the patient described here, endoscopic repair was technically easy and the good result was confirmed within a few days. In order to repair colonic fistulas following pancreatitis, application of endoclips could, in our opinion, provide a useful therapeutic option, feasible in selected patients.
