An extremely rare case of an oversized accessory spleen: case report and review of the literature.

BACKGROUND: The accessory spleen is a congenital defect characterized by a separated ectopic splenic parenchyma. The size is rarely more than 4 cm. The preoperative diagnosis is prohibitive preoperatively. The aims of the present manuscript were to present the case of a patient with a rare oversize accessory spleen and a review of the literature. CASE PRESENTATION: A 15-year-old boy was admitted to the emergency department following blunt abdominal trauma. The computed tomographic scan showed a traumatic rupture of the spleen and a 7-cm mass at the left side of the retroperitoneal space. Conservative treatment started and aborted after 4 h due to the onset of haemodynamic instability. Splenectomy was performed. An accessory spleen was discovered. A second large mass in the retroperitoneum was diagnosed as a second large accessory spleen that was also left in place. The postoperative course was uneventful, and the patient was discharged on the 7th postoperative day. Seven months later, the CT scan showed viability of both accessory spleens. CONCLUSION: An accessory spleen can be variously located and the retroperitoneal position is extremely uncommon. Preoperative diagnosis is still difficult, especially in emergency and as in our case, the literature shows the difficulty of reaching a diagnosis before surgery. The main misdiagnosis is neoplastic disease and for this reason accessory spleen can be wrongly removed. An undiagnosed pre or intra operative retroperitoneal mass, closely to the spleen, have to be managed carefully. The diagnosis of accessory spleen needs to be ever considered as if found, represents a great possibility to conduct a normal life after splenectomy (of main spleen) for trauma.

Open conversion for laparoscopically difficult cholecystectomy is still a valid solution with unsolved aspects.

The difficult laparoscopic cholecystectomy remains a surgical challenge for surgeons who must decide between laparoscopic continuation and open conversion. The balance between the lack of open surgery training of young surgeons and the risk of maintaining the laparoscopic approach in difficult laparoscopic cholecystectomy is still an unresolved problem. Furthermore, the time that must be spent in an attempt to complete laparoscopic surgery before conversion is still controversial. The authors in this letter discuss about these and other questions that still require an answer.

Effective of laparoscopy for post-operative small bowel adhesion in children.

AIM: The aim of this paper is to report a case of a child with adhesive small bowel obstruction treated by laparoscopic ap-proach. CASE REPORT: A 13-year old patient developed a small bowel obstruction caused by adhesion. He was successfully treated by laparoscopic adhesiolysis and was discharged from the hospital on the 7th post-operative day in satisfacto-ry condition. DISCUSSION: this disease is treated by laparoscopy very rarely, especially in children. In patients without comorbidities, such as pulmonary or cardiovascular diseases, laparoscopic approach could be considered as the first approach in children because the patient has the advantage of less pain and short hospitalization. CONCLUSION: Until clinical trials will address guidelines, when possible, laparoscopic approach should be attempted.

A new modified Mayo technique: should the surgeons need a new open technique for hernia repair in their armamentarium?

INTRODUCTION: The Mayo technique is one of the most common techniques used to repair incisional, umbilical, and epigastric hernias. A high percentage of recurrences, together with the use of particular expensive types of meshes, are some of the most relevant problems in this surgical field. PATIENTS AND METHODS: This study is a clinical prospective observational and involves all the patients who underwent procedures using a new modified Mayo technique from 2006 through 2013. The general criteria analyzed were age, sex, obesity, smoke abuse, diabetes, chronic diseases, type of hernia, operative time, morbidity and mortality. All the patients involved in this study were followed-up from 6 to 120 months. RESULTS: The types of hernia were 5 epigastic hernia (20,8%), 8 umbilical hernia (33,3%), 11 midline incision hernia (45,9%). Ten patients (41,7%) presented non-complicated hernias; 8 patients (33,3%) presented strangulated hernias and 6 patients (25,0%) presented obstructed hernias. No intestinal resection was necessary in any of the patients. The mean operative time was 55 minutes (range 30-180). The mean hospital stay of the patients' after-post operative procedure was 4.5 days (range, 2 to 8 days). No major complications have been reported. Only one patient present a recurrence. CONCLUSION: These preliminary results suggest that this modified Mayo technique could be useful in the armamentarium of surgeon to repair incisional, umbilical, and epigastric hernias. More studies are needed to validate the technique.

Anemia as One of Presenting Symptoms in an Adult with Cyst and Torsion of the Omentum - A Case Report.

BACKGROUND: Torsion is an uncommon disorder of the omentum and cysts are one of the rarest causes of omental torsion. To our knowledge, this is the first report of a case of an omental cyst presenting with both omental torsion and anemia. CASE PRESENTATION: We herein present a case report of a 41 year old indian female patient who presented with anemia (hemoglobin concentration 6.5 g/dL) and intermittent abdominal pain caused by torsion of a hemorrhagic omental cyst. A computed tomography scan, showed an omental cyst with free fluid in the abdominal cavity. At abdominal exploration, 1.5 L of hemorrhagic fluid was confirmed in the abdominal cavity. The cyst and twisted omentum were removed en bloc. The patient had an uneventful postoperative course and was discharged on day 8. At her 2-month follow-up, she was no longer anemic (hemoglobin concentration 10.7 g/dL). CONCLUSION: Cases of anemia associated with omental torsion have been reported in children; however, to the best of our knowledge, this is the first reported case of such a presentation in an adult. In such patients, surgical removal is the treatment of choice. Persons with recurrent abdominal pain and anemia must be assessed carefully and their differential diagnosis should include omental torsion. Appropriate diagnosis and treatment help avoid complications.

Role of laparoscopic peritoneal biopsy in the diagnosis of peritoneal tuberculosis. A seven-year experience.

The diagnosis of asymptomatic abdominal tuberculosis,without characteristic laboratory and radiologic findings, is difficult. We therefore investigated the role of diagnostic laparoscopy in patients with suspected peritoneal tuberculosis(PTB). Patients admitted to Hamad General Hospital, Qatar,who underwent laparoscopic peritoneal biopsy for suspected PTB from January 2004 to December 2010 were retrospectively analysed. Factors assessed included patient age, sex, symptoms,clinical signs, CT scan findings, laparoscopic findings andhistopathological diagnosis. A total of 41 patients, 33 males(80.5%) and 8 females (19.5%), of mean age 31 years, underwent laparoscopic peritoneal biopsy for suspected PTB duringthe study period. Abdominal pain was the most common presenting symptom, observed in 33 (80.5%) patients.Computerized tomography (CT) of the abdomen showed as citesin 37 patients (90%), bowel nodules in 22 (54%), peritoneal thickening and nodules in 37 (90%) and enlarged mesenteric lymph nodes in 11 (27%). The classical gross laparoscopic appearance of peritoneal tuberculosis was observed in 38 patients (93%), whereas laparoscopic findings were normal in 3 patients (7%). Histopathological results confirmed granulomatous inflammation in 38 patients (93%). The sensitivity and specificity of gross laparoscopic appearance in diagnosing peritoneal TB were both 100%. Two patients experienced complications from laparoscopy (5%), but there were nolaparoscopy-related deaths. Laparoscopic peritoneal biopsy isa rapid and safe method of accurately diagnosing PTB.

Diagnostic and prognostic value of alpha-fetoprotein, des-γ-carboxy prothrombin and squamous cell carcinoma antigen immunoglobulin M complexes in hepatocellular carcinoma.

The hepatocellular carcinoma (HCC) is one of the most common malignant tumors. It carries a poor survival rate and has an increasing incidence worldwide. In most cases, HCC is diagnosed at a late stage. Therefore, the prognosis of patients with HCC is generally poor and has a less than 5% 5-year survival rate. The aim of this study was compare the accuracy of α-fetoprotein (AFP), des-γ- carboxy prothrombin (DCP), squamous cell carcinoma antigen-immunoglobulin M complexes (SCCA-IgM Cs) in the early diagnosis and in the prognosis of HCC. A literature search identified the markers for hepatocellular carcinoma. A search of the literature was made using cancer literature and the PubMed database for the following keywords: "markers and HCC", "α-fetoprotein (AFP) and HCC", "Des-γ-carboxy prothrombin"(DCP) and HCC, "squamous cell carcinoma antigen-immunoglobulin M complexes" (SCCA-IgM Cs). Despite the large number of studies devoted to the immunohistochemistry of HCC, at the present time, the absolute positive and negative markers for HCC are still lacking, and even those characterized by very high sensitivity and specificity do not have an universal diagnostic usefulness. In conclusion none of the three biomarkers (AFP, DCP, SCCA-IgM Cs) is optimal. According to recent reviews, these biomarkers should be measured simultaneously and in combination with imaging techniques to increase the sensitivity, specificity, diagnostic accuracy and to make a reliable prognosis. Currently the recommended screening strategy for patients with cirrhosis includes the determination of serum AFP levels and an abdominal ultrasound every six months to detect HCC at an earlier stage.

[Complex partial seizure in patient with insulinoma: importance of early diagnosis]. / Crisi parziali complesse in un paziente affetto da insulinoma: l'importanza di una diagnosi precoce.

Insulinoma, usually benign (90%), is clinically characterized by symptoms as tremulousness, tachycardia, weakness, sweating, fatigue, hunger, headache, dizziness, disorientation and unconsciousness. However rarely it has an unusual presentation. We present a case of insulinoma misdiagnosed as neurologic disease. A 48-year-old man was admitted to our Emergency Division because of car accident caused by loss of consciousness. A diagnosis of complex partial seizure was made one year before. The patient appeared pale, tachycardic, BP 130/85 mmHg. Laboratory tests showed a severe hypoglycemia (30 mg/dl). He was treated with hypertonic glucose solution and the resolution of symptoms was obtained. Dosages of insulin and C-peptide, CT-scan and RMN confirmed a diagnosis of insulinoma. Seizure disappeared after surgical excision. The diagnosis of insulinoma is sometimes delayed up to more than 20 years. Neurologic or psychiatric presentation like disorientation, personality changes, amnesia, irritability, seizures, bizarre behavior, visual difficulties, neuropathy in patients affected by insulinoma could be cause of misdiagnosis. Diagnosis of insulinoma should always be considered whenever these symptoms occur, especially if unresponsive to specific therapy. Insulinoma is curable in most cases and an early diagnosis can avoid adverse consequences including neurologic damage.

Surgery of the aortoduodenal fistula: two cases with survival.

We report on two cases of aortoduodenal fistula. The patients underwent the positioning of an aortic stent 1.9 and 5 yearly before, respectively. They complained of fever and abdominal pain and were admitted to the hospital. A stent infection was suspected and an angio-CT confirmed the suspicion. Each patient was brought immediately to the operating room, where the fistula was individuated and resected, with closure of the aortic wall and excision of a part of the ulcerated intestinal loop involved. The infected stent was removed and an extra-anatomic bypass was performed. The patients survived and were discharged from hospital 38 and 29 days after the surgery, respectively, with no postsurgical sequelae and in good health. These patients are alive and in good health respectively 18 and 19 months (mo) after the procedure. If performed immediately upon diagnosis, this technique permits achievement of an optimal result.

Use of dissecting sealer may affect the early outcome in patients submitted to hepatic resection.

BACKGROUND: Many technological devices have been used to avoid intraoperative bleeding during hepatic parenchymal transection and to avoid morbidity and mortality, but until now none is complete. The aim of this work is to prospectively analyze hepatic resection patients treated with a water-cooled high frequency monopolar device in order to evaluate its effectiveness. PATIENTS AND METHODS: All consecutive patients who underwent liver resection by use of this device, between January 2003 until December 2007, were analyzed prospectively. The following variables were considered: age, sex, kind of disease, kind of liver resection, number of major/minor resections, total operative time and transection time, number and time of clamping, blood loss, time of hospitalization, morbidity, and mortality. RESULTS: Between January 2003 and December 2007, 26 patients were analyzed prospectively (69% women, 31% men). Ages ranged from 18 to 84 years. Sixty-five percent of patients had a malignant disease; 35%, a benign disease. The procedures performed were two major hepatectomies (7.6%) and 24 minor hepatectomies (92.4%). Hepatic transection was performed in 35 to 150 min. Total operative time range was 120-480 min. The average blood loss was 325 ml (range 50-600 ml). The mean postoperative stays were nine days for all the patient and six days for non-cirrhotic patients. CONCLUSION: The water-cooled high frequency monopolar device is useful for reducing ischemia-reperfusion damage due to the Pringle maneuver and for reducing the risk of morbidity. However, the Kelly forceps remains the only inexpensive instrument really essential for liver surgery.

Cholecystoduodenal fistula in a nonagenarian. Can laparotomy play a role in the era of laparoscopic? Case report.

Cholecystoduodenal fistula, a rare complication of biliary lithiasis, occurs in 0.5% to 3% of patients affected by cholelithiasis. Diagnosis is not easy and is usually incidental at surgery. The literature guidelines call for a laparoscopic approach to treating these patients; here, however, we report a case of a very elderly patient in which, among other reasons, open surgery was the treatment of choice to decrease morbidity and mortality.

Isolated hydatid cyst of the diaphragm without liver or lung involvement: a case report.

The most common targets of the echinococcus are the liver and the lung, but several organs can be affected by this disease. The isolated diaphragmatic location of the cyst, not associated with liver or lung, is very rare. The aim of this work is to report a case of hydatid cyst located in the abdominal side of the diaphragm and to review the literature. The diagnosis was fortuitous and at CT scan the cyst was apparently located on segment VII of the liver. During surgery, after dissection of the adherences with the liver, the cyst remained attached to the diaphragm. Thirty months after the resection, the patient is free of symptoms without any recurrence.

Emergency gastric ulcer complications in elderly. Factors affecting the morbidity and mortality in relation to therapeutic approaches.

AIM: In elderly the incidence of the emergency gastric ulcer complications, perforation and bleeding are increasing, with a difficult management of these patients for their concomitant diseases. The aim of this work is to analyze the therapeutical approach of emergency gastric ulcer complications in elderly patients, in order to establish the factors affecting the morbidity and mortality. METHODS: Patients older than 70 years, presenting gastric ulcer, observed in a tertiary University Hospital from 1995 to 2003, have been considered for the present study. Two groups of diseases have been examined: ulcer perforation and bleeding ulcer. Age, sex, risk factors, comorbidity, methods of diagnosis, ulcer characteristics, treatment, morbidity, mortality, hospitalization time and follow-up have been considered in each group. RESULTS: Thirteen elderly patients with perforated gastric ulcer have been observed: 9 (69.2%) females and 4 (30.8%) males with a mean age of 80.5 years (range 70-90). Four patients were hospitalized in suburban hospital with an average time between the diagnosis and the surgery of 36 h, while the remnants were hospitalized directly in our Department with a medium waiting time of about 2 h. The surgical procedures were: simple closure with omentum patch in 11 cases (84.6%), and antrectomy in 2 cases (15.4%), in which the antrum was multiply perforated. Two patients presented an ulcer larger than 2 cm treated with simple suture and omental patch without morbidity and mortality. Three patients (23%) died postoperatively, due to septic shock, ventricular fibrillation and intraoperative massive haemorrhage, 2 of these patients came from other hospitals. Twenty-eight elderly patients with bleeding gastric ulcer have been observed during the same period: 13 (46.4%) females and 15 (53.6%) males with a mean age of 79.6 years (range 71-91). Except 2 patients submitted to endoscopic treatment both with adrenaline injection, all the remnant patients were managed with medical therapy (H2-receptor antagonist or proton pump inhibitors and in 7 patients [24.1%] antihaemorrhage drugs), and clinical observation, with a endoscopic control 3-4 days after from the first endoscopy. One of the 2 patients endoscopically treated developed a ulcer perforation after 11 days, and the other one rebled, without possibility of any kind of treatment due to his instable condition of health. Three patients (10.7%) died during their hospital stay not for causes strictly due to the gastric haemorrhage. CONCLUSIONS: Our results suggest that the early diagnoses and early treatment are 2 basic factor on the prognosis of elderly patients with perforated gastric ulcer. The choice between simple closure, with or without vagotomy, or gastrectomy depends from preoperative and operative health conditions of the patient. In patients with ulcer larger than 2 cm, Graham's technique can be performed safely if the preoperative and intraoperative conditions are favourable. Elderly patients with gastric ulcer bleeding show an high risk of morbidity and mortality, related to the risk factors like non steroid anti-inflammatory drugs (NSAIDs) intake or smoke. Repeated endoscopy and antiulcer drugs can manage the high stage patients of Forrest's classification with a low rate of morbidity and mortality. According to literature surgical treatment should be reserved after the second failure of endoscopic treatment.

[Assessment of patient's comfort and functioning of a totally implantable venous system placed in the safenous vein]. / Valutazione del comfort del paziente e della funzionalità di un sistema totalmente impiantabile venoso posizionato in vena safena.

BACKGROUND: When venous system of superior vena cava is not useful or when chest wall is not utilizable to place a reservoir, saphenous vein can be utilized for totally implantable venous access device (TIVAD) placement. Aim of this work is to establish the best location of the reservoir for the function and the comfort of the patient. PATIENTS AND METHODS: All the patients submitted to TIVAD placement from January 1995 to October 2004 at the Department of Surgical Science, Organs Transplantations and Advanced Technologies of University of Catania have been considered to the present study. Age, sex, kind of disease, surgical procedure, early and late complications, function of the system and comfort to the patients in relation to the different site of reservoir placement have been studied. RESULTS: 447 TIVAD have been implanted in 258 males and 189 females aged from 31 to 79 years in the period considered for the study. Solid tumors represent the majority of the indications and all the TIVAD have been implanted by surgical cutdown to avoid all the early complications related to the percutaneous approach. Two patients received their TIVAD using saphenous vein by surgical cut-down, and no early complications have been recorded. The reservoirs have been placed respectively: in the chest wall in the first patient; and in the anterior wall of the abdomen, close to the anterosuperior iliac crest, firstly and later in the anterolateral face of the thigh in the second one. The first patient had non complications instead the second one referred discomfort with both reservoir locations. CONCLUSIONS: For the comfort of the patient related to the reservoir position in case of saphenous vein utilization chest wall should represent the best studies are required to validate the appropriate reservoir location.

[Use of the Floating Ball for hepatic resection in cirrhotic patients affected by hepatocellular carcinoma]. / Utilizzo del floating Ball nella chirurgia resettiva del carcinoma epatocellulare in pazienti cirrotici.

Done to the improvement of knowledges in hepatic surgery and postoperative care, hepatocellular carcinoma (HCC) have been treated more and more frequently by hepatic resection. Aim of this study is to report an initial series of patients affected by HCC treated by hepatic resection utilizing a new water-cooled, high-density, monopolar device, the Tissuelink Monopolar Floating Ball (Tissuelink Medical Inc., Dover, NH, U.S.A.), in order to avoid bleeding during hepatic surgery. Sex, age, kind of disease, viral and Child status, type of surgical procedure, in association to lenght of surgical procedure, blood loss, utilization of the vascular clamping of the liver, hospital stay, morbidity and mortality have been analized. Six liver resections have been performed utilizing this new device. No vascular clamping was established except one. No mortality was recorded. Morbidity was ascites in one case and pleural effusion in a second one. In conclusion the Floating Ball reduces the intraoperative bleeding during hepatic resection in patients with HCC.

[Colorectal liver metastases resected with safe margin achieved by tissuelink monopolar floating ball]. / Colorectal liver metastases resected with safe margin achieved by tissuelink monopolar floating ball.

BACKGROUND: Nowadays many technological devices are present in hepatic surgery to permit safer liver resections. Main purpose is decrease the intraoperative blood loss. The aim of this study is to analyze our initial experience in hepatic resections for liver metastasis using the new water-cooled, high-density, monopolar device, the Tissuelink Monopolar Floating Ball and Dissecting Sealer (Tissuelink Medical, Inc., Dover, NH). MATERIALS AND METHODS: We analyzed patients who underwent hepatic surgery for metastases from colorectal cancer between January 2003 and December 2004. Sex, age, type of surgical procedure, duration of the surgical procedure, blood loss, use of vascular clamping of the liver, length of hospital stay, morbidity, and mortality were analyzed. RESULTS: Three liver resection, one segmentectomy and two limited resections were performed with the use of these new devices. In one case the devices was used to increase safe free margin of hepatic resection. Average blood loss was 150 ml (range, 50 to 300 ml). No mortality or morbidity were recorder. CONCLUSIONS: In conclusion, this new device permits a bloodless liver resection avoiding vascular clamping. In plus the effect of radiofrequency waves can be useful to enlarge free resection border in patients submitted to hepatic resection without macroscopically safe margins. Prospective randomized studies are needed in order to establish the effective usefulness.

[Peritonectomy and hyperthermic chemoperfusion in peritoneal carcinomatosis. Preliminary results]. / Peritonectomia e chemioperfusione ipertermica nella carcinomatosi peritoneale. Risultati preliminari.

BACKGROUND: Peritoneal carcinomatosis can be actually treated by new surgical and oncological techniques. Aim of this work is to report preliminary results of a group of patients with peritoneal carcinomatosis, submitted to peritonectomy and intraperitoneal hypertermic chemoperfusion (IPHC). METHODS: Age, sex, type of neoplasm, peritoneal carcinomatosis index (PCI), completeness of cytoreduction (CC), operative time, morbidity and mortality of patients submitted to IPHC have been considered. RESULTS: From May 2001 to December 2004, 10 patients were submitted to peritonectomy and IPHC: 9 (90%) females and 1 (10%) male, aged from 49 to 72 years. Seven patients (70%) were affected of peritoneal carcinomatosis from ovarian tumor, three patients (30%) from colon cancer. The PCI was ranged from 8 to 25. The operative time was ranged from 6 to 14 hours. Two patients with a CC of 2 developed relaps and died respectively after 2 and 4 months. The remaining patients had a CC between 0 and 1. Of these last patients, 1 affected by ovarian cancer died 24 months after, 1 patient died 3 days after surgery for septic shock; the other patients are still alive with a period ranged from 1 to 30 months. CONCLUSIONS: Our preliminary results suggest that the peritonectomy and IPHC can be effective only in patients with CC of 0 or 1, in the remaining cases these therapeutical methods should be avoided.

[Learning curve and early complications of totally implantable venous access devices: is tutoring the solution for the problem?]. / La learning curve e le complicanze immediate dei sistemi totalmente impiantabili venosi: il tutoring come soluzione del problema?

During the last years operators implanting totally implantable venous access devices (TIVADs), type of access, and kind of complications are changed. Aim of this work is to evaluate the incidence of early complications during the learning curve of residents in surgery or inexperienced surgeons, besides considering the tutoring to evaluate its rule to prevent early complications. TIVADs, implanted by residents in surgery or by inexperienced surgeons in the Department of Surgical Science Organ Transplantation and Advanced Technologies of University of Catania from January 1995 to October 2003, have been considered for the present study. Age and sex of the patients, indication, type of surgical access and early complications of the TIVADs have been considered. Early complications are those complications that occur within 30 day after the implant. Ninety-five TIVADs were implanted by surgical approach in 95 patients: 58 males (61%) and 37 females (39%), with a mean age of 55 years (range 31-79). Inexperienced surgeons performed 40 implants (42%) instead resident in surgery implanted 55 TIVADs (58%). The migration out of the vein of a catheter 20 days after the operation was the only complication recorded. TIVADs implant by cut-down technique represent the way to avoid early complications. The learning curve is short and the tutoring is limited at the first phase.
