["Telescopic" terminoterminal pancreatico-jejunal anastomosis after duodenocephalopancreatectomy].

Pancreaticojejunostomy represents the most important step of the reconstructive process following pancreaticoduodenectomy. Anastomotic dehiscence at this level accounts for two thirds of total postoperative mortality. In order to reduce the incidence of anastomotic complications, we have recently adopted a new technique of "telescopic" end-to-end-pancreaticojejunostomy where, differently from our previous technique, we are not any longer invaginating the small bowel over the pancreatic stump. Our preliminary results obtained in 5 consecutive patients appear to be promising.

Adenocarcinoma

[Knight-Griffen ileo-proctostomy after total colectomy].

The double stapled colo-rectal anastomosis according to Knight e Griffen is currently used following an anterior resection of the rectum. The technical feasibility and the reduced risk of contamination represent the major advantages of the procedure. Accordingly, the Authors have adopted this technique to perform an ileo-rectal anastomosis following total colectomy. Furthermore, the use of a circular stapler with a small diameter allows to create a pseudo-valvular mechanism between the ileum and the rectum. Preliminary results obtained in 7 patients are presented.

Endoscopic approach to patients with portal hypertension: a complex diagnosis. A retrospective study based on 10 years' experience.

We analyzed the endoscopic findings in 788 patients with esophageal and gastric varices who underwent upper gastrointestinal endoscopy between 1 January 1979 and 31 December 1988. Of these, 154 patients (19.6%) had gastric varices associated in various patterns with esophageal varices. Congestive gastropathy, occurring with esophageal and gastric varices (43.4%), was the most frequent pathology detected in our patients. Esophagitis was present in 15.8% of patients, but did not correlate with variceal bleeding. Endoscopy performed at 1 day to 1 week post-hemorrhage in 313 patients accurately identified the source of bleeding in only 57.2% of patients. This figure increased to 98.2% when we performed the examination within the first 24 h of hemorrhage. In this group varices were the source of hemorrhage in 72.3% of patients while the hemorrhage came from other sources, such as erosive gastritis, duodenal and gastric ulcer in 27.6% of patients.

Endoscopic dilation of colonic postoperative strictures.

After the use of surgical staplers had become widespread, the number of colonic postoperative stenoses was observed to have increased. Nevertheless, the clinical relevance of this observation is minimal since only 2-5% of the patients complain of chronic constipation or obstruction symptoms. In such cases medical therapy is somewhat troublesome, and surgical treatment always implies a major operation. Endoscopic dilation has proved to be a reliable, simple, and safe therapeutic alternative. Forty-two patients with evidence of stenosis of either colocolic or colorectal anastomosis underwent mechanical or pneumatic dilation in our unit: 19 patients with a temporary diverting stoma were dilated before the colostomy was removed; in the remaining 23 cases, treatment was given according to the patients' symptoms or because it was not possible to pass the anastomosis with an endoscope. The overall failure rate was 2.4%, and no morbidity or mortality was found. When the percentages of patients successfully treated in one session alone were compared (76.9% versus 51.8%), balloon dilation was found to be more effective than bougienage. In our opinion, endoscopic dilation represents the mainstay of treatment of colonic anastomotic strictures, with surgery being reserved for the rare failures, when recurrence of cancer should be suspected.

[Integrated anastomosis using the Knight and Griffen technique].

The widespread use of mechanical staplers in gastrointestinal surgery has recently resulted in a simpler and faster operative technique. The double-stapled anastomosis (Knight and Griffen, 1980) seems to further simplify the technique of colo-rectal anastomosis, with reduced risks of pelvic contamination. Moreover, this technique can be used to reconstitute bowel continuity following an Hartmann's procedure or to perform an ileo-rectal anastomosis. The results obtained in 21 patients treated by this technique are presently reported.

Impact of biliary tract endoscopy on benign and malignant diseases.

In the last 15 years, the management of patients affected with obstructive jaundice has been greatly improved by the introduction into clinical practice of diagnostic and therapeutic biliary tract endoscopy. This method has provided better knowledge of the pathophysiology of diseases of the common bile duct (CBD), with enormous benefit for surgical decision making. Moreover, it has reduced morbidity and mortality in emergency patients as well as in high-risk patients with CBD stones. Even the incidence of retained stones has been reduced to almost 1%-2%. The impact of endoscopy on diseases of the biliary tract has been tremendous.

Biliary Tract Diseases

Morphological appearance of low-level echoes in the gallbladder. Interpretation with microscopic biliary analysis and clinical correlation.

A total of 743 patients affected by various gastrointestinal disorders were examined by ultrasound. The presence in the gallbladder bile of low-level echoes (LLE) was observed in 56 (7.5%). Twenty-six of these patients had surgery: 24 underwent cholecystectomy for important biliary-like painful symptomatology, and 2 had cephalopancreatectomy for pancreatic head carcinoma. Both macro- and microscopic controls of the bile were carried out in all 26 patients. In 20 cases, only microscopic cholesterol crystals and calcium bilirubinate granules were observed in the bile. The microscopic evidence of these crystals was associated in four cases with macroscopic evidence of so-called "biliary sludge" and in four cases with macroscopic evidence of highly viscous bile. In the other 6 cases these crystals were associated with the presence of cholesterol stones. The authors consider that the observation of LLE in the gallbladder bile is an important index of the presence of cholesterol crystals and/or calcium bilirubinate granules. These LLE can assume polymorphic aspects, described by the authors, which may simulate other pathologies and lead to incorrect echographic diagnosis. The high incidence of LLE in an alithiasic population (5.1%), together with the elevated frequency, according to the authors, of association of these echoes with a painful biliary-like symptomatology (52.6%), underlines the diagnostic importance of an accurate ultrasound investigation in this type of pathology.

Transrectal ultrasonography: three years' experience.

Since 1983 we have used radial and linear ultrasound probes in the laboratory and clinical examination of the rectum. Normal endosonographic appearances have been characterised by examining polyethylene membranes and resection specimens. Twenty normal subjects and 11 patients with rectal cancer have been examined, and of these 9 were correctly staged.

Humans

[Transgastric lymphadenography].

The transgastric lymphadenography technique carried out by the endoscopic route in 52 patients at the Digestive Endoscopy Centre of the 3rd Surgical Clinic of Rome University is described. On the basis of personal results it is considered that transgastric lymphadenography represents an interesting technique for the study of perigastric lymphnodes in normal and pathologic conditions. It is thought that it could also be useful in the study of the abdominal lymphatics although further verification and a larger series are necessary.

ERCP and EPT: Italian experience.

The use of endoscopy has had a satisfactory development in Italy and today at least 70% of Italian hospitals have a fiberscope. Most of the examinations performed are in the diagnosis of diseases of the oesophagus, stomach or duodenum, whilst only a small percentage are represented by coloscopy which is usually carried out in specialized units. One of the examinations, that is most rarely performed, is ERCP, even if some hospitals have a duodenoscope suitable for catheterization of the papilla of Vater. Regardless of the fact that the usefulness of this method has been recognized and that positive results are being reported from various centers throughout the world, ERCP in Italy is performed by very few endoscopists and only in very highly specialized centres. In Rome, for example, ERCP is performed only in our Centre of Digestive Endoscopy which furthermore has the only important experience in Italy in endoscopic papillo-sphincterotomy (EPT); this type of operation has, in fact, so far been carried out only in a very limited number of patients, in a few other endoscopy units.

ERCP, endoscopic papillotomy and gallstone removal by JFB2 Olympus and PFSB 1200 Machida.

ERCP is now used as routine technique and has provided a useful tool for both diagnostic and therapeutic purposes in diseases of the biliary tract. Until now this examination has been performed throughout the world including Italy, using preferably an Olympus JF and JF B2 sideviewing duodenoscope. In addition to 727 ERCP and 55 papillotomies performed using this instrument we have also employed a convertible endoscope Machida PFSB 1200; this fiberscope, with which front and side views are possible, can be used in the study of the oesophagus, stomach, duodenum, cannulation of the papilla of Vater and papillotomy. They results obtained and advantages offered by this instrument will be discussed. Since this endoscope is not usually employed, at least in Europe, for these purposes, we considered it of interest to report on the 251 ERCP and 9 papillotomies including stone removal performed in our department with the Machida PFSB 1200.
