[Interdigital pilonidal sinus in barbers].

Three cases of barber's hair sinus of the hand are presented. The lesion is produced by the penetration of extraneous short hairs into the interdigital spaces of the hand. The hairs produce an inflammatory reaction and foreign body granuloma. The clinical picture is usually benign but can be complicated by repeated infection which may require surgery. The structure of the lesions varies from epithelial-lined tract, cyst with surrounding foreign body reaction, to fibrotic cicatricial tissue. The exact reasons for the lesion are not known, but several theories are offered. It is, however, clear that since the 1970's Italian barbers have changed their methods of cutting hair, using their hands more than the customary instruments, i.e., combs, brushes, etc. The authors discuss the occupational problems due to the complications of disabling lesions.

[Rare malformation of the bile ducts of surgical interest].

Variations from normal anatomy of extrahepatic biliary tract, especially if on the basis of a congenital defect, are often dangerous for the surgeon, as hidden cause of a possible injury during surgery. During a cholecystectomy performed for lithiasis in non functioning gallbladder, whose preoperative cholangiogram revealed nothing of suspect, the dissection of cystic duct was regular at its normal junction with the Common Bile Duct (CBD). Because of the scheduled intraoperative cholangiogram, it was however not severed but only dissected free. The gallbladder was therefore detached from the liver in anterograde progression, after hemostasis and section of a normal cystic artery. During the detaching of gallbladder from the liver what seemed a very large "hepato-cystic" duct coming to the infundibulum was met: for caution the cholangiogram was then made proximally to such "hepato-cystic" duct that instead revealed to be the main right hepatic duct coming to the infundibulum of gallbladder without confluence with the left hepatic duct. The biliary tract going from the gallbladder to the supposed CBD was in fact the cystic duct, as the Heister's valvulae clearly show on the cholangiograms. Cholecystectomy was therefore performed proximally to the confluence of right hepatic duct, and the postoperative course was uneventful. Such kind of extrahepatic tract derangement must be very rare, because of the apparent lacking in literature of any similar case, also if the possibility is mentioned.(ABSTRACT TRUNCATED AT 250 WORDS)

[Correlation between post-cholecystectomy syndrome and biliary reflux gastritis. Endoscopic study].

Experimental reports have proved that bile acids damage the gastric mucosa. Moreover it is now accepted that duodenogastric reflux occurs in 20-30% of cholecystectomized persons. The Authors, with the purpose of defining a correlation between gastric mucosa damage by duodeno-gastric reflux and postcholecystectomy syndrome have taken into consideration two groups of 14 patients each. To the first group belonged cholecystectomized patients, who had episodic, often postprandial pain, constant heart burn, with associated vomiting and Hypochromic anemia. To the second group belonged asymptomatic patients with previous cholecystectomy. All these patients were endoscoped (EGDS), and their endoscopic biopsy specimens were surveyed. 99Tc HIDA cholescintigraphy was performed in all the groups of patients, after endoscopy. In 85% of symptomatic patients we found, during endoscopy, reflux of bile into the stomach with associated reddish and inflammatory change of antral mucosa vs. 7.14% of the control group. Atrophic chronic gastritis was found in 71.43% of endoscopic biopsy specimens of Symptomatic vs. 14.28% of asymptomatic patients. Superficial chronic gastritis was found in 28.57% of symptomatic vs. 50% of asymptomatic patients. At last we found active atrophic or superficial antral gastritis (Whitehead) in 90% of symptomatic patients vs. 0% of asymptomatic people. The Authors conclude that there is a positive correlation between duodenogastric reflux and postcholecystectomy syndrome when biliary reflux is correlated with an histological finding of antral active chronic gastritis.
