[Traditional cholecystectomy in a patient with situs viscerum inversus partialis]. / Colecistectomia per via tradizionale in paziente con situs viscerum inversus partialis.

The authors discuss the etiology of situs viscerum inversus partialis (SVIP), the associated anomalies and the malformations and the relative clinical problems, reviewing the international literature. The present a case of a 51 years old female with a diagnosis of umbilical hernia and cystocele. During hospitalization the patient complained a typical acute cholecystitis pain. The patient underwent ultrasonography, CT scan, and MNR that allowed us to diagnosis a calculous cholecystitis with SVIP and was elected for an open cholecystectomy. The Authors describe the surgical technique in relation to the anatomic anomalies, in particular vascular ones, that were discovered with the imaging studies and confirmed at laparotomy.

[Our experience in the recurrence of rectal cancer operated with radical intention in light of a case load treated in a homogeneous manner]. / La nostra esperienza delle recidive di cancri rettali operati con intento radicale alla luce dei risultati di una casistica trattata in maniera omogenea.

A reappraisal of the results obtained after potentially curative resection for rectal cancer compared with "historical" results is reported. An increase of the overall survival rates was registered as well as a corresponding lowering of the pelvic recurrences: 4.54% in the group of patients with a-two-year follow up. As for relapse surgery, however, reviewing the series from January 1991 to December 1994, the results are still poor because relapses were not resectable in 85.7% of the cases.

[The endoscopic treatment of postoperative stenoses of the upper digestive tract]. / Trattamento endoscopico delle stenosi post-operatorie del tratto digestivo superiore.

The authors compare their experience in dilatation of postoperative benign esophageal strictures. A total of 60 patients (37 males, 23 females: mean age 52), all with severe dysphagia, from January 1985 to September 1995, underwent endoscopic dilatation: 32 of these with Savary dilators and 28 with balloon dilators. Dilatation was effective in 93% in both groups. Two severe complications were recorded (1 heart attack and 1 perforation) in the group that underwent endoscopic dilatation with Savary dilators. During endoscopic management, pain recurred in 43% and 87% of cases after balloon or Savary dilatations, respectively. The authors believe balloon dilators are more effective, better tolerated and with less complications than Savary dilators. They reserve the management with Savary dilators to the extremely severe esophageal strictures.

[The intraoperative visualization of the bile ducts by the use of fluorescent substances. A feasibility study]. / Visualizzazione intraoperatoria delle vie biliari mediante impiego di sostanze fluorescenti. Studio di fattibilità.

Iatrogenic bile duct injury during cholecystectomy is the most serious complication of this surgical procedure. Initial reports suggest that this complication is particularly problematic during laparoscopic cholecystectomy. Proper identification of biliary anatomy in the subhepatic region is the only way to avoid this severe complication. The potential benefit from a simple, reliable method for intraoperative delineation of biliary anatomy is self-evident. In this experimental work the Authors-study the possibility and the feasibility of intraoperative biliary tree imaging with two fluorescent molecules (rolitetracyclin and fluorescin).

[Cholecystectomy and colorectal cancer: a retrospective study of a sample of 285 operated patients]. / Colecistectomia e cancro colo-rettale: studio retrospettivo su un campione di 285 pazienti operati.

A review of 285 patients operated for colo-rectal cancer in order to evaluate cholecystectomy rate in their pathologic history is reported. A surprisingly high rate (9.47%) was registered also when compared with Literature data. Although not definitely conclusive for a positive correlation between cholecystectomy and colo-rectal cancer, the Authors believe that this study identifies a subgroup of patients potentially at risk for colo-rectal cancer. In these subjects a prophylactic, periodic colonoscopy could be useful.
