[The preoperative staging of rectal cancer. A comparative assessment between endorectal echography and pelvic CT].

The authors report a comparative study between endorectal ultrasonography (EU) and computed tomography (CT) in the preoperative assessment of 94 patients with rectal cancer. In evaluating the depth of wall penetration of rectal tumors EUS and CT offered good results: EUS confirmed a clear superiority with overall accuracy of 88.4% versus 80% of CT. On the contrary, in detecting lymph node metastases both techniques had poor results obtaining a correct diagnosis in 75.6% of the cases with EUS and in 69.4% of the cases with CT. In conclusion, the authors believe that EUS and CT may by very useful in the study of tumor penetration of the rectal wall; while in the study of lymph node involvement new techniques for a more accurate diagnosis are needed.

[Surgical treatment of cervical fistula after esophagogastroplasty (EGP)].

The authors report their experience on cervical anastomosis dehiscence in patients who had total esophagectomy and esophagogastroplasty for esophageal neoplasms. They describe, accurately and step by step, the plastic reconstructive technique (by using a vascularized transposed cutaneous flap), used to treat a symptomatic cervical fistula which occurred in 3 of the 24 patients who had esophagectomy and cervical-esophagogastroplasty. This kind of treatment led to complete healing of the fistulas, without clinical and radiological signs of fistula recurrence in all the patients treated.

Gasless video-assisted reversal of Hartmann's procedure.

More than 60% of patients who are submitted to Hartmann's procedure refuse to undergo reversal. This procedure is in fact a major undertaking associated with significantly mortality and morbidity rates. The authors suggest a minimally invasive approach without pneumoperitoneum. A consecutive series of four male patients, average age 64 years, underwent laparoscopic assisted reversal of Hartmann's procedure in our department. The procedure was performed for intestinal malignant occlusion in two cases and for perforated diverticulitis in the other two. Mobilization was nearly immediate and incisional pain almost absent; peristalsis restarted after 36-48 h. Finally, the patients were discharged on day 6. Neither mortality nor morbidity occurred in the 8-month follow-up period. The authors conclude that this new laparoscopic procedure may lead to shorter hospital stays and increased acceptance by patients, while maintaining the same safety of the traditional open procedure.

[Postoperative biliary calculosis: our experience with therapeutic strategy].

The Authors report their experience in the treatment of 92 cases of post-surgical biliary tract stones: 17 early cases (18.5%) were treated by percutaneous nonsurgical extraction (10 cases) or by operative procedures (7 cases); 75 late cases (81.5%) were surgically treated. The Authors summarize the results of the treatment, discussing advantages and disadvantages of the various techniques.

Malignant lymphoma complicating ulcerative colitis.

Carcinoma of the colon as a complication of chronic ulcerative colitis is relatively common, whereas malignant lymphoma is apparently rare. We report two cases of patients with malignant lymphoma complicating ulcerative colitis, a CD 30 + T-cell lymphoma of the intestine and a low grade B-cell non-Hodgkin's lymphoma of MALT type. It is important to be aware of the possibility of malignant lymphoma in ulcerative colitis in order to evaluate correctly any lymphoid infiltrate seen in a biopsy, especially when anti-inflammatory treatment seems to be ineffective or when symptoms change.

Subcutaneous right leg metastasis from rectal adenocarcinoma without visceral involvement.

The occurrence of cutaneous metastasis from colorectal cancer is rare, with a reported frequency of less than 4 to 5 percent. Typically signifies widespread disease and a poor prognosis. Metastases from adenocarcinoma of the colon-rectum usually occur within two years of resection of the primary tumour, and the average survival of a patient with cutaneous metastasis has been reported as ranging from 3 to 18 months. The case reported here concerns a patient who developed a skin metastasis without evidence of visceral involvement after treatment of rectal carcinoma. It is advisable to implement cutaneous biopsy in patients with a history of carcinoma; this may establish the diagnosis of metastatic disease and change the methods of therapeutic intervention and prognosis.

[Role of surgery in the treatment of primary gastric lymphoma and assessment of new therapeutic approaches].

Controversy remains regarding the best treatment for primary gastric lymphoma (PGL). Recent developments in diagnosis and chemotherapy have changed strategies for this disease. Fourteen patients with primary gastric non-Hodgkin's lymphoma underwent surgery. Before surgery 9/14 patients underwent Helicobacter pylori eradication, and 4/14 were treated with chemotherapy. In two patients chemotherapy was not possible because of risk of perforation recurred. Total gastrectomy with N2 lymphadenectomy, splenectomy, biopsy of mesenteric lymph nodes, and hepatic biopsy were done. Then patients underwent post-operative chemotherapy. Involved-field radiation therapy was made in four patients. The overall survival was 64.2 percent. Surgery was the treatment of choice in cases of gastric lymphoma non-responsive to medical therapy and to control complications or when gastroscopy did not supply correct diagnosis.

Impact of laparoscopy and ultrasonography in gastrointestinal malignancies.

BACKGROUND/AIMS: An adequate preoperative disease staging is highly required before surgical treatment, even in gastrointestinal malignancies. Our study wants to give a contribution in order to define echolaparoscopy weight in gastrointestinal tumors and its impact in surgical therapy. METHODOLOGY: 33 patients were affected by pancreas, 22 by stomach, 16 by extrahepatic biliary tract and 18 by liver cancers; every patient was considered worthy of radical or palliative surgery according to preoperative staging (thorax-abdominal CT and percutaneous ultrasonography). Paired sample t-tests were used to analyze the results of each methodical and probability values of less than 0.05 were considered significant. RESULTS: Preoperative instrumental examinations gave correct evaluations only in 44 of 89 cases (49%) while echolaparoscopic gave correct evaluations in 82 on 89 cases (92%) (P<0.05). So after echolaparoscopic in only 7 cases we performed an explorative laparotomy. CONCLUSIONS: Laparoscopy and ultrasound impact on therapy is worthy of attention. It seems to be able to give advantages in staging gastrointestinal malignancies, except for pancreas cancers, in which some limits and negative aspects have been demonstrated, regarding the possibility of giving correct diagnosis of portal axis infiltration.

The elongation of the internal carotid artery. Diagnosis and surgical treatment.

Cerebro-vascular insufficiency is rarely caused by an abnormal elongation of the internal carotid artery (the ratio is 15% to 17% of symptomatic patients). The anomalies can be defined as: tortuosity, when the artery has a "C" or "S" shape; coiling, when the elongation is more evident and the artery forms one or more loops; kinking, when there is a sharp angulation of the first portion of the internal carotid artery. The etiology of these peculiar arterial modifications seems to be related to a congenital basis which may become exaggerated with ageing of the artery. Surgical correction should include intra-arterial inspection (TEA) as well as eliminating the pathological elongation. The Authors presents their 9 cases surgical experience.
