RESUMO
There are several therapeutic options for fecal incontinence but often they do not achieve good results in the long run. This study dealt with sacral nerve modulation, a new therapeutic option. Twenty-one patients underwent pudendal nerve evaluation (PNE) at our institution. Nine patients were affected by both fecal and urinary incontinence, 3 had fecal incontinence and anal pain, 5 had fecal incontinence and pelvic floor dyssynergia, and 4 had isolated fecal incontinence. They underwent morphological, functional and psychological tests prior to PNE, showing no sphincter rupture, almost normal anal pressures, impaired rectal sensation and deficient psychological pattern. All patients underwent at least two nerve evaluations. Four of 21 patients (19%) were selected to receive a permanent sacral electrode, as PNE seemed to have improved their symptoms by >75%. A median follow-up of 15 months (range, 6-24 months) showed that this method decreases weekly episodes of incontinence and increases maximal squeeze pressure. We demonstrated an increase in basal pressure in 3 of 4 patients (all with isolated fecal incontinence). Rectal sensation threshold decreased in three patients; urge threshold decreased in two patients and increased in two patients, but in each patient we got a stabilization. We evaluated the quality of life by applying the Short Form Health Survey test (SF-36). All 4 patients showed a significant increase in the scores of physical, emotional and social role functioning after the permanent implant. In conclusion, sacral nerve modulation may improve physical, physiological and social quality of life in selected groups of incontinent patients without gross sphincter lesions and with impaired rectal sensation.

Impaired gallbladder motility may contribute to gallstone pathogenesis by providing time for nucleation and aggregation of cholesterol crystals. Simultaneous scintigraphic-ultrasonographic techniques have been proposed to assess alternating phases of gallbladder emptying and filling. To evaluate patterns of gallbladder motility and of postprandial bile flow by means of a single ultrasonographic technique, 12 healthy volunteers and 20 gallstone patients underwent minute-by-minute gallbladder ultrasonography for 3 h postprandially. Mathematical analysis of volume measurements was used to estimate hepatic and cholecystic bile flux through the gallbladder. Compared to controls, gallstone patients showed greater amounts of unexchanged cholecystic-to-hepatic bile (11% vs. 1%, p <.001) and most of them showed impaired gallbladder washout efficacy. Utrasonographic values of bile exchanges were similar to those derived from scintigraphic-sonographic studies in comparable groups of subjects. This study provides new ultrasonographic variables, which better express gallbladder bile retention in gallstone patients and strongly discriminate gallstone patients from controls.

A 73 years-old woman presented with locally advanced breast cancer (cT4b cN1 M0, stage IIIB) and atrial flutter. Because of the arrhythmia, chemotherapy or tamoxifen, although malignancy was hormone-sensitive, were discarded. Letrozole was started. Two months later, the breast nodule and skin ulceration cleared up. Surgery was performed. Nowadays, 24 months later, patient does fine, continuing letrozole as adjuvant treatment.

A case of a 32-years old man with a long lasting history of inflammatory bowel disease (IBD) is described. He was treated in the past with adequate medical therapy with considerable improvement of the symptoms. However, after the resolution of the last episode of abdominal pain and diarrhoea, because of multiple protruding masses and sub-stenotic regions found during a colonoscopy, the patient underwent a right enlarged hemicolectomy with jejunal resection. During the surgical procedure 16 enlarged lymphnodes were removed. The histological examination of the surgical specimen showed the presence of numerous Reed-Sternberg cells, compatible with a diagnosis of Hodgkin's disease (HD). None of the removed lymphnodes showed the presence of tumor cells, and in addition the systemic staging procedure was negative. After staging, the ABVD regimen was started, achieving a complete clinical and pathological response. This is a rare case of primary extranodal HD localized to the colon, in a patient with a long standing history of IBD, who showed an optimal response to chemotherapy. The case and the differential diagnosis with other pathological entities of the bowel is discussed.

PURPOSE: There are several options in the treatment of fecal incontinence; it is often difficult to choose the most appropriate, adequate treatment. The consolidated experience gained in the urologic field suggests that sacral nerve stimulation may be a further option in the choice of treatment. The aim of our study was to evaluate the preliminary results of the peripheral nerve evaluation test obtained in a multicenter collaborative study on patients with defecatory and urinary disturbances. METHODS: Forty patients (9 males; mean age, 50.2; range, 26-79 years) underwent the peripheral nerve evaluation test, 28 (70 percent) for fecal incontinence and 12 (30 percent) for chronic constipation. Fourteen (35 percent) patients also had urinary incontinence; six had urge incontinence, two had stress incontinence, and six had retention incontinence. Associated diseases were scleroderma (2 patients), spinal injuries (4 patients), and syringomyelia (1 patient). All the patients underwent preliminary investigations with anorectal manometry, pudendal nerve terminal motor latency testing, anal ultrasound, defecography, and if required, urodynamic tests. The electrode for sacral nerve stimulation was positioned percutaneously under local anesthesia in the S2 (4), S3 (34), or S4 (1) foramen unilaterally (1 patient not accounted for because of no response to acute test), based on the best motor and subjective responses of paresthesia of the pelvic floor. Stimulation parameters were average amplitude, 2.8 (range, 1-6) V and average frequency, 15 to 25 Hz. RESULTS: The mean duration of the tests was 9.9 (range, 7-30) days; tests lasting fewer than seven days were not evaluated. There were four early displacements of the electrode. In 22 of the 25 evaluable patients with fecal incontinence, there was an improvement of symptoms (88 percent), and 11 (44 percent) were completely continent to liquid or solid stools, whereas in 7 symptoms were unchanged. Mean number of episodes of liquid or solid stool incontinence per week was 8.1 (range, 4-18) in the prestimulation period and 1.7 (range, 0-12) during the peripheral nerve evaluation test. (P = 0.001; Wilcoxon's signed-rank test). The most important manometric findings were: increase of maximum rest pressure (39.4 +/- 7.3 vs. 54.3 +/- 8.5 mmHg; P = 0.014, Wilcoxon's test) and maximum squeeze pressure (84.7 +/- 8.8 vs. 99.5 +/- 1.1 mmHg; P = 0.047), reduction of initial threshold (63.6 +/- 5.2 vs. 42.4 +/- 4.7 ml; P = 0.041) and urge sensation (123.8 +/- 0.6 vs. 78.3 +/- 8.9 ml; P = 0.05). An improvement was also found in patients with constipation, with reduction in difficulty emptying the rectum, with prestimulation at 7 (range, 2-21) episodes per week and end of peripheral nerve evaluation test at 2.1 (range, 0-6) episodes per week, P < 0.01) and in the number of unsuccessful visits to the toilet, which dropped from 29.2 (7-24) to 6.7 (0-28) per week (P = 0.01). The most important manometric findings in constipated patients were an increase in amplitude of maximum squeeze pressure during sacral nerve stimulation (prestimulation, 63 +/- 0 mm Hg; end of peripheral nerve evaluation test, 78 +/- 1 mm Hg; P = 0.009) and a reduction in rectal volume for urge threshold (prestimulation, 189 +/- 52 ml; end of peripheral nerve evaluation test, 139 +/- 45 ml; P = 0.004). CONCLUSIONS: In functional bowel disorders short-term sacral nerve stimulation seems to be a useful diagnostic tool to assess patients for a minor invasive therapy alternative to conventional surgical procedure.

PURPOSE: Sacral nerve modulation appears to offer a valid treatment option for some patients with fecal incontinence and functional defects of the internal anal sphincter or of the striated muscle. METHODS: Sixteen patients with fecal incontinence (4 males; mean age, 51.4 (range, 27-79) years) with intact or surgically repaired (n = 1) anal sphincter underwent permanent sacral nerve stimulation implant. Cause was traumatic in two patients, and associated disorders included scleroderma (2 patients) and spastic paraparesis (1 patient); eight (50 percent) of the patients also had urinary incontinence, and two (12.5 percent) had nonobstructive urinary retention. All patients were selected on the basis of positive findings from at least one peripheral nerve evaluation. The stimulating electrode was positioned in the S2 (1 patient), S3 (14 patients), or S4 (1 patient) sacral foramen. RESULTS: Mean follow-up was 15.5 (range, 3-45) months. Mean preimplant Williams score decreased from 4.1 +/- 0.9 (range, 2-5) to 1.25 +/- 0.5 (range, 1-2) (P = 0.01, Wilcoxon test), and the number of incontinence accidents for liquid or solid stool in 14 days decreased from 11.5 +/- 4.8 (range, 2-20) before implant to 0.6 +/- 0.9 (range, 0-2) at the last follow-up. Important manometric data were an increase in mean maximal pressure at rest of 37.7 +/- 14.9 mmHg (implantable pulse generator 49.1 +/- 18.7, P = 0.04) and in mean maximal pressure during squeeze (prestimulation 67.3 +/- 21.1 mmHg, implantable pulse generator 82.6 +/- 21.0, P = 0.09). CONCLUSIONS: Neuromodulation can be considered an option for fecal incontinence. However, an accurate clinical and instrumental evaluation and careful patient selection are required to optimize outcome.

Inflammatory pseudotumor of the liver is a rare entity of unknown etiology; fewer than 80 cases have been reported in the world literature. Its appearance on the computerized tomography, ultrasound and magnetic resonance have been previously described as nonspecific, and clinical presentation is not helpful in the diagnosis. This is why the diagnosis usually is made after laparotomy and often after the excision of the tumor. Several recent reports show that drug therapy is effective and lead to tumor regression, while other authors believe that an aggressive approach should be taken, due to the potential adverse impact of its vascular invasive and biliary obstructive nature. Herein we describe a case of this clinical entity, which occurred in a 52 years old patient, where the operative examination showed bilobar involvement, treated with right hepatectomy and contra-lateral tumor excision in the clinical suspect of hepatocellular carcinoma. The detailed clinical, radiological and pathological picture is described. At 6 months follow-up the patient conditions are excellent. On the basis of the available literature, we discuss the clinical features and the therapeutical problems of such rare clinical entity, and propose a selected use of liver biopsy when the clinical suspicion of pseudotumor can be considered, in order to achieve a preoperative diagnosis and therefore to avoid surgery.

Haemorroidal disease has often typical presentation with rectal bleeding, anal prolapse and pain. Practitioners and patients usually underestimate the symptoms; in adults and older people the same symptoms may suggest neoplastic disease, which may be synchronous. Proctoscopy is the main diagnostic test for staging; endoscopic examination with biopsy is helpful to differentiate neoplastic, granulomatous and inflammatory anorectal lesions. In our mind, a complete study of anorectal function and morphology is necessary for a correct diagnosis.

Many new surgical and nonsurgical approaches to the treatment of hemorrhoids have been described: sclerotherapy, rubber band ligation, cryosurgery, anal dilatation, infrared photocoagulation, bipolar diathermy, and electrocoagulation. Which one is most effective depends on the size and degree of hemorrhoids, but surely depends as well on the experience of each proctologist. In the modern treatment, fast and painless procedures that can be carried out in the office practice under local anesthesia will be more and more indicated.

Anastomosis dehiscences after gastrectomy are a major post-operative complication often resulting in the death of the patient. 13 patients with dehiscences resulting in enterocutaneous fistulae have been treated with parenteral and/or enteral nutrition. Spontaneous closure rate was 84.6% and mean time for fistula closure was 22.4 days from the onset of nutritional treatment. On the base of nutritional effectiveness no difference could be found between enteral and parenteral nutrition in this series.
RESUMO
A computerised program devised to manage patients undergoing TPN has been operating in the Parenteral and Enteral Nutrition Unit of the II Clinica Chirurgica of the University of Rome. The program includes sections to manage information, monitoring and therapy. The package was compiled using the new Language C, which is well adapted to our model. In a pilot study the program was successfully applied to the management of 15 patients. Computers and information technology have developed to the point where they are well suited to this type of biological application. Language C, which in this study, was used for the first time in this field, offers practically unlimited possibilities for development.
RESUMO
One hundred and seventeen patients with chronic anal fissure were submitted to subcutaneous internal lateral sphincterotomy. Immediate pain relief was observed in all patients except two, in whom sphincterotomy was incomplete. One hundred and ten patients had their first painless bowel movement 24 to 48 hours after the operation. Temporary incontinence to flatus was reported by 38 patients, whereas fecal incontinence was never observed. Healing time of the wound was six days, that of the fissure four weeks. In the 98 patients followed at six months and one year, no complications or recurrences were reported. If particular technical precautions are taken, this type of operation presents several advantages over other procedures, namely posterior midline sphincterotomy and anal stretching.

Lymphatic fistula is a rare surgical complication, which mainly occurs after cervical or retroperitoneal lymph node dissection and which frequently requires a surgical repair. A small series of nine postoperative lymphatic fistulas treated conservatively with total parenteral nutrition (TPN) is reported. All the patients were malnourished at the beginning of the TPN, and all exhibited an objective improvement of their nutritional status after completion of the treatment. Due to the interruption of the enteral alimentation or to the nutritional repletion, spontaneous closure of the fistula was achieved in eight of nine patients treated with TPN longer than 1 week. The authors conclude that whenever the immediate surgical repair is not recommended, or it is not successful, a 2- to 3-week course of TPN may be used with the chance of spontaneous healing. In any case, patients conservatively treated by TPN can undergo a delayed operation with minimal risk because of the improved nutritional status.
