Inguino-crural hernias: preoperative diagnosis and post-operative follow-up by high-resolution ultrasonography. A personal experience.

BACKGROUND: Hernia is an important pathology with an incidence of 5% in world population. The more affect region is the inguino-femoral. Normally the diagnosis was based on the clinical exam. A short time ago the high resolution ultrasonographic study was introduced. The purpose of our study was to value the sensitivity of US-HR in the preoperative diagnosis, in the postoperative follow-up and to compare the results to clinical exam. METHODS: 140 patients affect by inguino-femoral hernia underwent this study, 112 inguinal hernias, 28 femoral, 8 pediatric patients. 106 patients underwent repair through the prosthesis, in 34 Halstad-Postempsky's technique was carried out. Ultrasonography studied: a) inguino-femoral region, cord and scrotum (the study was effected in basal condition and through Valsalva's manoeuver, decubitus changes); b) hernia content (omenutm, bowel); c) hernial orifice and of hernial content's transit (direct or indirect); d) the relation with the inguinal ligament; e) the vascularization (power-doppler) and the pathological situation (presence or absence of liquid in the sac, parietal thickness, presence/absence of peristalsis), in case of hernia complication; f) the presence/absence of simultaneous pathologies (hydrocele, varicocele, cord's cyst). The postoperative study was effected after 7 days, 1-6-12 months we have observed: a) haematomas and seromes (under the skin, under the aponeurosis, scrotal); b) prosthesis displacement; c) prosthesis infection; d) prosthesis reject; e) recurrence (importance, site); f) we have carried out the treatment of the complications (echoguided drainage of serous and hematic collection). RESULTS: The sensitivity of US-HR in the diagnosis of hernia was 87.5%. The clinical exam arrived at an average of 72%, the comparison was favourable to US-HR (15.5%). The sensitivity in the diagnosis of complication arrived at an average of 85.5% for US-HR, and of 36% for clinical exam; the gap between the two techniques was elevated (49.5%). CONCLUSIONS: The US-HR showed an important accuracy and sensitivity thus to cover today an important role, after the clinical exam, in the preoperative diagnosis and in the postoperative follow-up of the inguino-femoral hernias.

[Palliative treatment of neoplasms of the bilio-pancreatic area. Surgical diversion treatment versus endoscopic-percutaneous approach]. / Trattamento palliativo delle neoplasie del distretto bilio-pancreatico. Terapia derivativa chirurgica versus approccio endoscopico-percutaneo.

Bilio-pancreatic (BPD) tumours are pathologies with an overall resectability rate of 20-25%, with a high percentage of patients directed towards palliative treatment (70-90%). One hundred and twenty-eight patients underwent palliative treatment for BPD tumours. The M:F ratio was 1:1.5 and the mean age 61 years. The tumours were topographically divided into: 84 (63%) localised in the pancreatic head region; 34 (25%) biliary duct tumours and 6 arising in the ampulla of Vater. 42 patients (30%) underwent palliative surgical treatment (group 1) and 86 (70%) received non-surgical treatment (endoscopic percutaneous) (group 2). We also performed 6 gastrointestinal by-passes (GEA). The early morbidity rate was 36% in the first group and 12.8% in the second. The incidence of late morbidity in the first group was nil, with a mean survival of 10 months. Mortality was nil in both groups. Surgical by-pass is advisable in the presence of patients with a longer life expectancy and in good clinical condition but presents a high rate of early morbidity and a low percentage of late complications. The authors conclude that validity of the methods is similar. They believe that, in selected cases, surgical treatment remains the therapy of choice for BPD tumours.

[Preoperative diagnosis using color Doppler flowmetry in focal and diffuse thyroid pathology]. / Diagnostica preoperatoria mediante flussimetria color-Doppler delle patologie focali e diffuse della tiroide.

Color-doppler was first used in the study and classification of specific pathologies in 1992. One hundred and eighteen patients with focal and diffuse thyroid pathologies underwent color-doppler, flowmetry analysis and peak systolic velocity measurement (CD-FM-PSV). The PSV results allowed us to identify two subclasses a and b in class three and four (a: = < or = 30 cm/sec., b: = > 30 cm/sec.). Class 3a and 3b lesions are the most likely to represent neoplastic nodules. Based on our results, we assigned 58 patients to type 2 (follicular hyperplasia), 20 patients to type 3a (follicular adenoma and carcinomas), 16 patients to type 3b (carcinomas and Plummer's adenoma), 15 patients to type 4a (autoimmune thyroiditis and hypothyroidism) and 12 patients to type 4b (Graves' disease). Preliminary results were compared with FNAB, intra-operative and post-operative histological data. The specificity of CD-FM-PSV in diagnosis is 86%. We have concluded that CD-FM-PSV is an effective imaging technique for pre-operative diagnosis of thyroid pathologies and along with FNAB, a adequate predictive tool for thyroid nodules.

[Echo-guided percutaneous drainage of abscesses and abdominal fluid collections]. / Drenaggio percutaneo ecoguidato degli ascessi e delle raccolte fluide addominali.

Abdominal abscesses are pathologies characterized by an high decree of mortality and morbidity. The pathology was once dealt with surgery evacuation the percentage of success reaches 60% while mortality runned around 24%. Today this technic has been substituted by the echo-guided treatment. The minimal invasive approach reduced dramatically the cases of complications (4-6%) and mortality (4%); it is highly suggested in the majority of the cases of visceral or endoperitoneal abscesses. Our study case counts 57 echo-guided drainages due to multiply surgery pathologies. The number of successful ends runs on 93%, this perfect agrees with the data given by literature that states a decree of success around 90%. We did no test an higher or lower decree of complications nor mortality. According to our opinion the echo-guided drainage is a primary technic in abdominal septic collections. Surgery drainage has to be aside for patients with general good health or for collections accompanied with divertcular disease of the large intestine, crohn disease, rectocolitis ulcerosis and periappendix abscess.

[Abdominal compartment syndrome in video laparoscopic surgery. Etiopathogenetic aspects, physiopathology and personal experience]. / La sindrome addominale compartimentale in chirurgia videolaparoscopica. Considerazioni etiopatogenetiche, fisiopatologia ed esperienza personale.

The abdominal compartment syndrome (ACS) is a very seven pathology, consequence oh abdominal injuries and traumatism, acute pancreatitis, aortic aneurism rupture, acute peritonitis. The etiopatogenesis is the increase of intra-abdominal pressure with systemic consequences for cardiorespiratory and renal failure. The authors after careful physiopathologic consideration, describe, a case report of ACS in the laparoscopic cholecystectomy for acute cholecystitis. To conclusion, we report very important the accurate intraoperative monitoring of vital parameters (PCO2, PO2, Pa, Fc, PVC, Ph, Diuresis) and immediate decision at laparotomic conversion for abdominal decompression.

[Gynecomastia: diagnosis and therapy update]. / La ginecomastia: attualità diagnostiche e terapeutiche.

The Authors report their experience in the management of gynaecomastia. Physiologic, pathologic and iatrogenic causes of the lesion, as well as possible interfering mechanisms, and diagnostic protocol are examined. When there is no spontaneous regression or when the precipitating factors are eliminated surgery is the therapeutical choice, also because it helps in resolving the related psychological problems affecting these patients.

[Current trends in the treatment of perforated colonic diverticulitis]. / Attualità nel trattamento della diverticolite perforata del colon.

The authors, after having examined the cases of complicated diverticulitis operated between 1985 and 1993, confirm that the surgical treatment for this particular pathology is strictly dependent on the local or general seriousness. In the light of this they consider an operation for resection and anastomosis 1st stage justifiable only in selected cases; colostomy and drainage in particularly serious cases, preferring Hartmann's method of operation for the 3rd and 4th stages of Chappuis and Chon. The results obtained agree in a satisfactory manner with the data in the literature.
