Arterial vasculature of the stomach and oncologic gastrectomies.
Preoperative knowledge of the gastric arterial blood-supply with special regard to anatomic anomalies is desirable for a correct surgical approach to this viscus and for the reduction of intra- and postoperative complication rates. The authors report their experience with the use of preoperative digital angiography in the evaluation of 46 consecutive patients undergoing gastric cancer surgery. Twenty of these (43.5%) presented a vascular anatomy different from the normal pattern. In 6 (13%), a double arterial anomaly was detected. Some anatomic anomalies of the celiac axis and superior mesenteric artery are described in relation to operative procedures during oncologic gastrectomies.

Senior versus proctored young and resident surgeons' experience in laparoscopic cholecystectomy: is there any need of previous exposure to open biliary surgery?
Since its introduction in 1987 laparoscopic cholecystectomy (LC) has gained rapid acceptance as the preferred management of symptomatic cholelithiasis. In our department, during the past 3 years, the number of open cholecystectomies (OCs) has dramatically decreased. The impact of the introduction of LC as a part of the overall surgical procedures performed by residents is analyzed. To date junior-level residents have already more experience in LC than in OC. Indeed in our teaching unit junior-level residents performed only 5% of biliary surgical procedures in open surgery. Residents participated in the "surgeon's" position in 47.9% of the LCs and as either surgeon or first assistant in 100%. We analyzed both the cases where residents acted as surgeons and where they did not. It appeared that there was no difference in the complication and conversion rates. More intraoperative cholangiographies (IOCs) were performed by residents. This was probably due to the anxiety of making a mistake because of their lack of experience. This report suggests that the decrease in the number of OCs is not a drawback and that it is possible to acquire an adequate knowledge of biliary anatomy and surgery from LC training, if strict proctoring criteria are respected.

Laparoscopic management of volvulated Meckel's diverticulum.
Laparoscopy in the emergency setting is a logical extension of this technique. Open laparoscopy is particularly useful in the management of the acute abdomen. In our institution, after a sequential work-out that includes physical examination, laboratory data, plain abdominal roentgenograms and ultrasonography, diagnostic laparoscopy is advocated. We present the laparoscopic treatment of an intestinal obstruction caused by a volvulus around Meckel's diverticulum. The efficacy and safety of the diagnostic and/or therapeutic laparoscopic procedures in the emergency setting are discussed.

[Diagnostic accuracy of computerized tomography. Preoperative staging of gastric cancer].
"Imaging techniques" have assumed greater clinical value in the further assessment of an endoscopically or radiologically verified neoplastic lesion of the stomach through the ability to evaluate its extent of invasion, metastatic involvement of lymphnodes and/or distant organs. US, CT, and more recently NMR are non-invasive modalities that provide an accurate preoperative assessment of potential surgery decision making. Common current practice of preoperative CT in gastric cancer and relevant results documented in letterature, have inclined many clinicians in its use in staging this disease. The aim of the study is to evaluate and assign the efficacy of CT imaging in the preoperative staging of gastric cancer by comparing the results obtained with this imaging technique with the postoperative histopatologic findings of 25 patients with adenocarcinoma of the stomach. CT demonstrates the primitive lesion as a gastric wall differentiate T1 (parietal invasion extending to the lamina propria and submucosa) and T2 (invasion of the muscolaris propria and the submucosa). The performance values of CT in detecting tumor extension to the sierosa were as follows: sensitivity of 78%, specificity of 63%; and overall accuracy of 72%. The sensitivity and specificity of CT in demonstrating adjacent organ involvement were approximately 75% and 85% respectively, and overall accuracy of 84%. In the detection of metastatic involvement of lymphnodes CT demonstrated to be 70% sensitive, 62% specific with an efficacy of 68%. In terms of M-stage, CT imaging identified liver metastases in 3 patients (2 located in the VII segment and 1 in the IV) and 1 metastasis to the adrenal gland. All were confirmed by specimen histopathologic findings.

[Long-term results of surgical treatment of early cancers of the stomach].
The postoperative course of 172 patients with early gastric cancer operated between 1974 and 1987 was reviewed with a median follow-up of 7 years. The survival probability at the end of 1989 was 0.916 (excluding operative mortality and other causes of death) or 0.876 when the operative mortality was included. Univariate analysis showed a significant survival difference according to the presence or absence of submucosal invasion (p = 0.02, Log-Rank test) and lymph node invasion (p = 0.04, age greater than or less than 50 years (p = 0.03) and according to the type of resection performed (total gastrectomy with gastric and perigastric lymph node dissection or subtotal gastrectomy with incomplete lymph node dissection (p = 0.05). Eleven patients died from cancer recurrence, one is still alive with a recurrence of the gastric stump. The other deaths were due to cancers of other organs (6), cardiovascular disease (2), pneumonia (3), septicaemia (1) and a car accident. Although the prognosis of early gastric cancer is relatively favourable in European countries, patients must be carefully followed for a long period because of recurrences and the high incidence of cancers in other organs.

Surgical anatomy of the papilla of Vater and biliopancreatic ducts.
The present research was aimed at defining the surgical anatomy of the biliopancreatic ducts and of Oddi's sphincter. The numerous anatomic variations of the papilla, the millimetric distribution of its muscle fibres, and any morphological detail of clinical significance have been investigated. An integrated analysis of radiographic, tridimensional (casts), and histologic findings has been carried out in 49 of 64 autoptic bilio-duodenopancreatic specimens. Exact limits of the choledocus and Wirsung sphincters were defined. A consistent accumulation of circular muscle fibres could be seen, on the choledocus duct side, up to a mean distance of 13.6 mm from the papillary pore. However, more rarefied fibres were present up to 20.5 mm. Muscle fibres were seen to stop roughly on the pancreatic duct side at 7.3 mm from the papillary pore. The beginning of the sphincter was observed 2-3 mm above the papillary pore. There was no evidence suggesting the presence of upper, middle, and lower biliary sphincters. Five anatomic diversities of the Wirsung-choledocus confluence were found. The Y type was the most frequent (61.2%), followed by the U type (22.4%), V (14.3%), and II (2.1%). Santorini's duct with a normal papilla was present in 16 per cent of the cases. These data along with other interesting observations on antireflux mechanisms (Santorini's valves) and on the ductal space orientation appear to be useful guidelines for a physiopathological understanding of bilio-pancreatic diseases and for any therapeutic procedure on these structures.

[Laparoscopic diverticulectomy for ileal volvulus on Meckel's diverticulum].
Laparoscopy in the emergency setting is a logical extension of this technique. Open laparoscopy is particularly useful in the management of acute abdomen. In fact, after a sequential work-out that includes physical examination, laboratory data, plain abdominal x-rays and ultrasonography, diagnostic laparoscopy is advocated. The Authors herein report a case of intestinal obstruction (volvulus due to Meckel's diverticulum) treated with laparoscopy. The efficacy and safety of the diagnostic and/or therapeutic laparoscopic procedure in the emergency setting are discussed.

[Surgical treatment of 4th-stage hemorrhoids: the role of anatomical techniques].
Surgical options for fourth-degree hemorrhoids are still matter of debate. The high incidence of the disease encouraged research and brought to technical improvements able to achieve a painless, reliable, harmless and well tolerated surgical treatment. The Authors report a retrospective study of 193 patients who underwent surgery for fourth-degree hemorrhoids. In these cases the Authors advise anatomic techniques using local anaesthesia with i.v. administration of sedatives, thus allowing a 24-hour hospitalization.

Early gastric cancer: follow-up after gastrectomy in 159 patients.
The postoperative course of 159 patients with early gastric cancer operated on between 1974 and 1987 was followed for a median of 7.3 years. The cumulative 10-year survival rate(s.e.) calculated using follow-up data to the end of 1989 was 90.6(2.7) per cent excluding operative death and that from causes other than gastric cancer, or 86.3(3.0) per cent when operative mortality was included. The overall 10-year survival rate(s.e.) was 77.3(3.7) per cent. Univariate analysis showed a significant difference in survival rates between cancers confined to the mucosa and those with submucosal invasion (P = 0.02), between patients with and without lymph node metastases (P = 0.05) and between those < or = 50 and > 50 years of age (P = 0.02). Using Cox multivariate analysis and a stepwise procedure for eight variables (sex, age, depth of invasion, lymph node metastases, presence of ulceration, location, histological type, type of surgery), age and histological type had the most significant effect on survival. Seven operative deaths were recorded. Eleven patients died from recurrent cancer and one is still alive with a gastric remnant recurrence. Other causes of death were metachronous primary cancer (six patients), cardiovascular disease (two), pneumonia (three), sepsis (one) and car accident (one). Although the prognosis of early gastric cancer is relatively good in western countries, patients should be carefully followed over a long period for late recurrence and for metachronous cancer, which has a high incidence.

Lost intraperitoneal stones after laparoscopic cholecystectomy: harmless sequela or reason for reoperation?
Laparoscopic cholecystectomy has become the "gold standard" in the therapy of noncomplicated cholelythiasis. Gallbladder perforation with bile and calculi spreading in the abdominal cavity is one of the most frequent intraoperative complications of laparoscopic cholecystectomy. When not recognized during surgery or unproperly treated, it may lead to intraperitoneal abscess formation and may require a reoperation. We report a case of an intraperitoneal abscess with a cutaneous fistula, a site of a mucopurulent exudate, and stone spillage after an unrecognized gallbladder perforation and residual lithiasis in the peritoneal cavity found 3 months after laparoscopic cholecystectomy.

Primary adenocarcinoma arising in the jejunal limb of a Roux-en-Y esophagojejunostomy: a case report.
Adenocarcinoma of the small bowel is uncommon. Due to the paucity and lack of specificity of symptoms, patients are usually seen late in the course of their illness when curative therapy, mainly represented by wide surgical resection, is unlikely. The authors report a case of primary adenocarcinoma arising in the jejunal limb transposed for a Roux-en-Y esophagojejunostomy reconstruction eight years after a total gastrectomy performed for an advanced gastric cancer (pT2N1M0), with mixed histological pattern (tubular-mucinous) and negative CEA staining of cancer cells. Evidence for excluding the possibility of a recurrence of the primitive gastric cancer was based on the different histologic pattern, positive CEA staining of cancer cells and other features of the second neoplasm. Early diagnosis of the neoplasm was made possible by its favorable anatomic location and the early onset of symptoms, which prompted effective surgical therapy (wide resection). The authors, furthermore, analyze and discuss the possible pathogenesis of the neoplasm, based on the evidence of slow jejunal limb emptying, elevated concentration of N-Nitroso compounds and contamination by N-nitrosating bacteria in the jejunal limb juice, suggesting that each of these factors could have had a role to play in the development of the jejunal malignancy.

[The drug treatment of postoperative pain].
The study, conducted on 40 patients with pain resulting from "minor" general surgery, for the purpose of evaluating the efficacy and tolerability of ST-679 (administered in a single oral dose of 1200 mg in 20 patients) and to compare them with those of paracetamol (administered in a single oral dose of 1000 mg in 20 patients), demonstrated that the new drug was active on all recorded parameters and superior to the reference drug. The evaluation of the evolution of pain, performed using the Scott-Huskisson visual analog scale, evidenced that the maximum analgesic efficacy of ST-679 is reached after 1 hour and 15 minutes from assumption and remains unaltered until the final observation (6 hours). The paracetamol registers maximum analgesic efficacy after 30 minutes, but does not remain constant for the entire observation period. All the other parameters evaluated (variation in pain intensity, peak of analgesic activity and total remission of pain) are significantly favorable to ST-679. The tolerability of ST-679 was very good and better than the reference drug.

Low anterior resection versus abdominoperineal excision: a comparison of local recurrence after curative surgery for "very low" rectal cancer.
In the controversy regarding whether sphincter-saving resection (SSR) or abdominoperineal resection (APER) is more appropriate for the treatment of very low rectal cancer, local recurrence rates seem to play a fundamental role in patient outcome. In order to operate an effective patient selection, very low rectal cancer is defined herein as being located within 4.5 to 7.5 cm from the anal verge. This retrospective report investigates the incidence of local recurrence after curative surgery for very low rectal carcinoma in 24 consecutive patients treated by the same surgical team over a 15-year period using the above surgical procedures. In the APER group, the local recurrence rate was 45.5%, occurring in 5 of 11 cases; and in the SSR group 46.1%, occurring in 6 of 13 cases, with no significant difference between the two groups. Recurrence was found within one year of surgical treatment in all except one case. Despite the strict follow-up program, it was only possible to perform reoperation in two recurrent cases, both previously submitted to SSR and diagnosed by means of transanal ultrasonography and macrobiopsy. The high incidence of local recurrence in this series is explained by the advanced stage of disease in the majority of cases. Thus, as the choice between APER and SSR does not seem to affect the incidence of local recurrence, which is related more to tumor size, site, stage, and grading, preservation of the sphincters and restoration of digestive continuity should be achieved whenever technically possible.

Retrograde jejunogastric intussusception: is endoscopic or surgical management more appropriate?
Jejunogastric intussusception (JGI) is a rare complication which can develop after partial gastrectomy, gastroenteroanastomosis or enteroanastomosis. Although its management is usually surgical, an endoscopic reduction can alternatively be attempted. We present herein a case of acute JGI in which failure of endoscopic reduction required surgical resection and reconstruction. This is followed by a discussion based on the current available literature.

A rare cause of digestive hemorrhage: an aneurysm of the superior pancreaticoduodenal artery rupturing into the duodenal stump of a Billroth II partial gastrectomy.
We report herein a case of an iatrogenic superior pancreaticoduodenal arterial aneurysm which ruptured into the duodenal stump of a Billroth II partial gastrectomy. Superselective angiography was used for the diagnosis, and successful embolization performed nonoperatively. A review of the literature revealed both the etiology and site of rupture in this case to be extremely uncommon.

[Technique and immediate results of the Moreno Gonzalez-Carboni reconstruction after total gastrectomy].
Reconstruction following total gastrectomy for gastric cancer is still matter of debate. The Roux-en-Y esophagojejunostomy and the interposed loop esophago-jejunoduodenostomy are the techniques commonly employed. The Authors describe their modification of Henley's jejunal interposition and report early results achieved in a series of 60 consecutive patients.
