Spontaneous rupture of a hepatic epithelioid angiomyolipoma: damage control surgery. A case report.

BACKGROUND: Angiomyolipoma (AML) is a rare mesenchymal tumor composed by blood vessels, adipose tissue and smooth muscle cells in variable proportions. Although it is most often diagnosed in the kidney, this tumor may originate from any part of the liver. It is often misdiagnosed as hepatocellular carcinoma (HCC) or other benign liver tumor. We describe a case of spontaneous rupture of hepatic angiomyolipoma in a young woman, with evidence of internal hemorrhage and hemoperitoneum. CASE REPORT: Liver tumor rupture is a rare but real surgical emergency. In our case it has been managed according to the trauma principles of the damage control surgery. At the time of the observation, the patient presented an instable condition, so the decision-making was oriented toward a less invasive first step of liver packing instead of a more aggressive intervention such as one shot hepatic resection. CONCLUSION: Damage control surgery with deep parenchymal sutures of the liver and pro-coagulant tissue adhesives packing abbreviates surgical time before the development of critical and irreversible physiological endpoints and permits a more confident second time surgery. This surgical management concept helps to reduce the mortality rate and the incidence of complications not only in traumatic liver damages, it works very well in spontaneous liver ruptures as well.

Massive bleeding in an adult patient suffering from Meckel's diverticulum.

The case of a 22-year-old male who bled from a Meckel's diverticulum is described. The diagnosis was achieved after 99mTechnetium pertechnetate scintigraphy. With the administration of somatostatin very clear images were obtained. The histological examination confirmed the presence of ectopic gastric mucosa. The literature, over the last 10 years, has been reviewed to identify factors associated with bleeding in adults. Ectopic gastric mucosa is the most important factor predicting bleeding. The diagnostic approach to bleeding Meckel's diverticulum and the improvement in the quality of 99mTechnetium pertechnetate scintigraphy, following administration of somatostatin, is discussed.

Immunoscintigraphy in malignant melanoma: a five-year clinical experience.

Immunoscintigraphy (IS) with 99Tcm-labelled anti-melanoma monoclonal antibody F(ab')2 fragments was performed in 135 melanoma patients, 64 males and 71 females, aged 19-82 years (mean 52.3 years) between December 1987 and December 1991. The first group of IS was performed in 50 patients before surgery to assess optimal management: seven true positive and one true negative were obtained in ocular and visceral melanomas, while in cutaneous MM sensitivity, specificity and accuracy in assessing lymph node involvement were, respectively, 61.5, 93.3 and 83.7%. The second group of 128 IS is relative to 85 patients in follow-up: excluding 13 cases with known metastatic disease and 12 inconclusive tests, sensitivity, specificity and accuracy were, respectively, 83.3, 98.8 and 96.1%. Immunoscintigraphy is free of side effects even after repeated administrations and is a useful adjunct to standard diagnostic techniques as a basis for treatment decisions.

Surgical management of ascending saphenous thrombophlebitis.

BACKGROUND: Acute saphenous vein ascending thrombophlebitis is recognised to be a dangerous condition due to the reported high incidence of deep vein thrombus involvement and possibly fatal pulmonary embolism. We assessed the accuracy of duplex scanning in determining the extent of thrombosis as well as the effectiveness of surgical treatment. METHODS: We retrospectively reviewed 146 patients referred to our Vascular Laboratory for acute superficial thrombophlebitis from 1987 to 1997. Duplex scanning identified 85 cases of superficial thrombophlebitis involving at least a segment of the saphenous vein localised below the knee (58.2%); 37 of thrombophlebitis extending into both the superficial and deep venous systems (25.3%), and 24 of saphenous thrombosis extending to within 5 cm of the saphenofemoral junction (16.4%). The latter group underwent saphenofemoral disconnection. We compared the preoperative duplex with the surgical reports and evaluated the surgical results. RESULTS: We did not observe any complication. Return to work and normal activity occurred within 3-5 days. When varicose vein thrombectomy was performed concurrently, the patients had better postoperative pain control. CONCLUSIONS: Duplex scanning showed 100% accuracy both in determining the presence of thrombosis and its extent. Saphenofemoral disconnection for thrombosis involving the saphenofemoral junction is a safe procedure and can be performed on an outpatient basis.

Laparoscopic approach for esophageal achalasia with epiphrenic diverticulum.

We report the case of a 65-year-old woman with a 10-year history of dysphagia, regurgitation, cough, and 10-kg weight loss caused by an epiphrenic diverticulum associated with esophageal achalasia managed with a laparoscopic approach. A preoperative barium swallow showed a dilated sigmoid esophagus with a 6-cm epiphrenic diverticulum. Esophageal manometry confirmed the absence of peristalsis in the esophageal body. We performed a laparoscopic diverticulectomy and a 7-cm distal esophageal myotomy with a Dor fundoplication. The postoperative course was uneventful. On the third postoperative day a barium swallow showed no leak, and the patient started oral intake. She was discharged home 5 days after the operation free of symptoms and tolerating a soft diet. Sixteen months after surgery, she was asymptomatic and had gained 8 kg. A barium swallow showed a normal-size esophagus with regular emptying. We reaffirm the feasibility, safety, and efficacy of the laparoscopic diverticulectomy and distal myotomy with Dor fundoplication to manage epiphrenic diverticula resulting from esophageal achalasia.

[Prospective surgery in the treatment of acute pancreatitis]. / Prospettive chirurgiche in corso di pancreatite acuta.

A series of 65 patients with acute pancreatitis is analyzed with special regard to ethiopatogenesis and therapy. In several cases (68%) surgery has been performed with good results. Results are discussed and confronted with bibliographic report. The main problem, according to Authors, is to diagnose the real cause of pancreatitis for every patient, so that is possible to choose the appropriate may of treatment.

[Laparoscopic treatment of Mirizzi's syndrome]. / Trattamento laparoscopico della sindrome di Mirizzi.

The Mirizzi syndrome is an unusual benign obstructive jaundice due to extrinsic mechanical compression of the common hepatic duct by gallstone impacted within the neck or cystic duct of the gallbladder. This syndrome is described either as an acute form due only to extrinsic compression of the common bile duct (type I) or as a chronic form resulting in an erosive cholecysto-choledochal fistula (type II). Up to date, the syndrome remains a clinically and surgically challenging problem. The anatomic basic of the syndrome (an anomalous relationship between the cystic duct and the common hepatic duct) when associated with inflammation and interbiliary fistula predisposes to a critical situation to be clearly detected and contributes to technical difficulties when surgical management is performed. The operative diagnosis of Mirizzi syndrome remains elusive and requires careful scrutiny of the biliary tract imaging to recognize the diseased duct system and to facilitate the following operative procedures. The surgical treatment requires a skill and careful operative dissection of the duct system, cholecystectomy and a safe biliary exploration and stone clearance, avoiding any iatrogenic damage to common hepatic duct. Laparotomy is commonly advocated as the safer approach to the diseased biliary tract and it is still employed by most authors. The laparoscopic surgery has not yet entered as the first-choice procedure for this syndrome due to jaundice and acute inflammation considered by some as contraindication to mini-invasive treatment. This paper describes successful surgical management by laparoscopic techniques in two patients affected by Mirizzi type I and type II syndrome treated by cholecystectomy alone and cholecystectomy with choledochal fistula flap repair, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

[Simultaneous and independent multifocal neoplasms of the large intestine]. / Neoplasie multifocali, simultanee ed indipendenti del grosso intestino.

The Authors report the presence of two simultaneous neoplasms of the large bowel which are independent of each other from the histological point of view. The Authors point out the more interesting aspects of this particular neoplastic pathology, which creates different clinical syndromes; diagnosis and therapeutic possibilities were investigated. The frequency of these neoplasms is not exceptional, and, therefore, the possible existence even in subjects having a single tumor of the colon or rectum should not be neglected.

[Emergency surgery for complicated colorectal cancer. Retrospective study]. / Trattamento chirurgico del cancro colorettale complicato. Studio retrospettivo.

INTRODUCTION: Emergency surgery for the complications of colorectal cancer poses a significant surgical problem with published mortality rates as hight as 25% to 30%. We reviewed the results of the analysis and quantification of the influence of complications on the outcome of the patients who underwent emergency colectomy for colorectal cancer. MATERIALS AND METHODS: Retrospective study of the clinical features from, a series of 63 patients operated on from 1991 to 1997 (12% of all colorectal cancer operations in the same period). The correlations between complications and cancer stages were estimated by the KW (ANOVA method). RESULTS: Fifty-three patients underwent colorectal resection for intestinal occlusion (84%), 5 for perforation (8%) and 5 for lower gastrointestinal bleeding (8%). When the cancer complications were correlated to the different cancer stage at operation, the complications rate were 32%, 32%, and 36% in the stage II, stage III, and stage IV, respectively. This data was statistically significant: (KW = 58, p = 0.0001). The overall mortality rate was 8% (5 patients) and the total postoperative morbity rate was 32% (21 patients). The overall 5-year, 3-year, and 1-year survival was 47%, 48%, and 76% respectively. CONCLUSIONS: Emergency surgery for complicated colorectal cancer can be performed safely with low postoperative morbidity and mortality rate and can be advocated to realize both short and long-term survival rates comparable to elective surgery; the KW test supports the hypothesis that the a complication in the natural history of colorectal cancer doesn't correlate with the stage of disease.

[The ideal length of hospital stay in the surgical treatment of colorectal cancer]. / La lunghezza ideale del ricovero per il trattamento chirurgico del cancro colo-rettale.

In order to verify the safety of an ideal length of hospital stay (5-6 days) after open colectomy, we reviewed complications after 371 consecutive, elective colorectal resections for cancer at our institution between April 1991 and December 1998. Specifically, age of the patient, length of hospital stay and when the complication was diagnosed were registered. The median postoperative hospital stay was 9 days (range, 4-34 days). No difference in length of hospital stay was detected in patients < or = 65 years old versus > 65 years old (P = NS). All major complications (anastomotic leak, intestinal bleeding, intestinal occlusion, pneumonia, pulmonary embolism, pulmonary edema, stroke, angina pectoris, and fascial dehiscence) were diagnosed before the fifth postoperative day (P < 0.05). Among the minor complications (vomiting, packed red blood cells transfusion, diarrhea, wound infection, urinary tract infection, and pleural effusion), none requiring hospitalization was detected later then 5 days after the operation. We conclude that postoperative length of stay after colorectal resection for cancer can be reduced safely to five to six days after the operation.

[Malignancy: treatment and prognosis of gastrointestinal and pancreatic endocrine neoplasia: retrospective study of a series of 16 cases]. / Malignità: trattamento e prognosi delle Neoplasie Endocrine Gastrointestinali e del Pancreas: studio retrospettivo su una serie di 16 casi.

The aim of this study was to review our experience with endocrine tumours of the gastrointestinal tract and pancreas (ETGIP). Between February 1991 and March 2000, sixteen patients with ETGIP were operated on at our institution. Of these patients we reviewed preoperative symptoms, diagnostic techniques (ultrasound, CT, MRI, radiolabelled octreotide scintigraphy, angiography, immunohistochemical study), treatment (surgical operation, neoadjuvant and adjuvant chemotherapy, and radiometabolic therapy) and survival. Nine patients (56%) had a carcinoid tumour, three (19%) an unspecified endocrine tumour, and four (25%) an endocrine tumour associated with a non-endocrine neoplasm. Only five patients (31%) had a preoperative diagnosis of endocrine tumour. Eight patients (50%) had metastatic disease at the time of the operation. All patients without preoperative metastasis (eight patients, 50%) are still alive without recurrent disease, with a mean postoperative survival of 36 months (12-60 months). Of eight patients with metastatic disease, six (75%) died after a mean of 20.5 months (3-60 months) and two (25%) are still alive with the disease after 3 and 6 months, respectively. These data show that presence of metastasis strongly influence survival. Furthermore, survival of patients with metastatic disease seems to be longer as compared to other gastrointestinal tract malignancies. ETGIP are more common and aggressive than previously believed and, therefore, early diagnosis is crucial for cure. Nowadays, however, new diagnostic tools such as radiolabelled octreotide scintigraphy are available for diagnosis and postoperative follow-up. The optimal treatment for ETGIP is a multimodal approach with surgical operation, chemoradiation, radiometabolic, and genetic therapies.
