BACKGROUND/AIMS: The authors are interested in determining the diagnostic and surgical approach followed in different Italian institutions in the treatment of adenocarcinoma of the head of the pancreas, whenever the spleno-mesenteric-portal confluence is invaded. METHODOLOGY: A 10-item questionnaire was sent to 21 Italian Centers of Surgical Oncology and a total of 1185 patients treated with pancreaticoduodenectomy were collected from 15 centers. Among them, 164 spleno-mesenteric-portal vein (SMPV) resections were performed. RESULTS: In all collaborative centers, the diagnostic work-up is comparable with what is reported in the literature. An accurate pre- and intra-operative staging and a differential diagnosis between inflammatory and neoplastic involvement of the vessel walls is universally considered essential for its surgical and oncological implications. If vessel involvement is ruled out, 7 centers proceed to pancreasectomy anyway. Direct end-to-end vein reconstruction is used as the primary procedure, but interposition of PTFE and autologous vein grafting may be used. An overall 4.8% post-operative complications only have been reported. Mean perioperative mortality reported is 3.8% (0-11.5%) and morbidity is 22.8% (4.7-57%). Survival rate is 10 months overall. The mean actuarial 5-year survival is 12%. CONCLUSIONS: The attitude of the collaborative centers in cases of SMPV involvement varies, with a slight majority favoring a conservative behavior. Surgical resection extended to the vessels is still uncommon, even in centers mostly experienced in surgery of the pancreas. We believe that vascular resections can be safely performed in both of the different conditions: localized tumors locally invading the vessels and neoplasms with massive invasion of the peripancreatic structures. We share with others the opinion that, in experienced centers, extensive resections should have a role for palliation of carcinoma of the pancreas whenever they offer a better quality of life, although life expectancy may not be positively influenced.

[2 cases of choledochal calculosis associated with juxtapapillary diverticulum in patients with gastric resection: submesocolon approach].

Although laparoscopy and endoscopy have reduced the need for laparotomies in biliary tract surgery, open surgery is sometimes still needed. One case in particular is when previous operations have significantly distorted normal upper abdomen anatomy. We chose an inframesocolic entrance to the posterior peritoneum in two patients with bile duct stones, juxtapapillary duodenal diverticulum and a history of cholecystectomy and partial gastric resectioning. The duodenum was reached at the junction between the second and third section by entering the posterior peritoneum through the inferior sheet of the mesocolon, a relatively avascular area. The diverticulum was incised, the sphincter and papilla operation was performed and the bile duct stones removed. The diverticulum was then resected. Our conclusion is that in certain cases, an inframesocolic entrance can significantly reduce technical difficulties involved in re-operating through dense adhesions, minimize surgical time and blood loss and, when operating through the open diverticulum, spare an unnecessary duodenotomy.

Hepatocarcinoma: considerations on surgical treatment in a personal series of 23 patients.

BACKGROUND/AIMS: Surgical treatment of primary liver tumors has undergone significant changes in recent years because of improved surgical and anesthesiological techniques and better pre- and post-operative care. We review our personal series from 1987-1995. METHODOLOGY: Of 31 cases of hepatocellular carcinoma (HCC) observed in the years 1987-1995, 23 underwent curative resective surgery for a total of 24 liver resections: 6 hepatectomies; 10 segmentectomies; 4 atypical subsegmentectomies; 2 extended resections, with excision of neoplastic thrombi within the portal vein; 1 orthotopic liver transplantation in another institution, and 1 limited segmental resection for tumor recurrence. In 7 recent cases, pre-operative transcatheter arterial chemoembolization (TAE) was used. RESULTS: The mean survival of the 13 patients that are known to be deceased is 27 months (range: 7-114 months). Perioperative mortality was nil. Actuarial 5-year survival rate is 27%. Pre-operative TAE was used in 7 patients: 4 out of 7 lesions were significantly reduced at computed tomography (CT) scan control 21 days following TAE, while in 3 the tumor size was unchanged. CONCLUSIONS: Liver surgery, even major resections, has become safe with no perioperative mortality in our series. In our experience, pre-operative TAE has often produced significant reduction of the mass, but its real efficacy is still the subject of debate. TAE and percutaneous ethanol injection (PET) should be evaluated as part of combined multimodality treatment in the therapy of large lesions previously considered inoperable.

[The conservative surgery of Crohn's disease: the long-term results].

INTRODUCTION: Patients with Crohn's disease (CD) receive one or more surgical interventions throughout their clinical history. Conservative surgery has recently been proposed as a safe and effective option for the treatment of complicated CD and for the prevention of short bowel syndrome and stoma. PATIENTS AND METHODS: One hundred nineteen patients affected by CD were treated with stricture plasty and mini-resection in our Department between January 1993 and January 1998. At admission, the prior complete clinical and surgical history of each patient was collected and then inserted in a prospectively maintained data base. Analysis of recurrence was made using the Kaplan-Meier function and the influence of certain variables on the risk of recurrence was analyzed using a Cox proportional hazard model. RESULTS: Perioperative mortality was nil, postoperative complications occurred in 8 patients (6.7%). Overall long term surgical recurrence at 5 years was 28%, 35% in patients operated on within one year and 15% in those treated after one year from the diagnosis (p < .05). CONCLUSIONS: Stricture plasty and minimal resections show lower perioperative mortality and postoperative complications similar to resective surgery. From risk factor analysis, a group of patients with high risk of surgical recurrence emerged. In this group and whenever technically possible, we consider stricture plasty and minimal resection the gold standard in the treatment of complicated CD.

[Surgical treatment of ulcerative rectocolitis: technical aspects of total restorative proctocolitis with S pouch].

Restorative proctocolectomy with an ileal-pouch-anal anastomosis seems to be the treatment of choice for ulcerative colitis. The aim of this study was to discuss a number of technical and functional aspects of the procedure that still appear to be controversial such as the shape of the pouch, the mucosectomy and the type of anastomosis. The authors report on their experience with the surgical treatment of ulcerative colitis with an "S" pouch. The technique reported, however, differs from the original method proposed by Parks and Nicholls in 1978 and the reasons for this surgical choice are discussed. A six-year experience (1993-1999) regarding 35 patients undergoing this approach is reported. No perioperative deaths were observed. The early and long-term complication rates were 8.5% and 11.4%, respectively. The average number of daily evacuations was 4. Mucosectomy affords complete resolution of the disease, while the particular shape of the pouch guarantees good functional results.

Impact of the introduction of laparoscopic cholecystectomy on the population aged 70 and over.

BACKGROUND/AIMS: Laparoscopic cholecystectomy is reported to be better tolerated than open cholecystectomy by patients aged 70 and over. We evaluate its impact on patients aged 70 and over, from one single center. METHODOLOGY: We review 427 cholecystectomies performed in one single centre, from November 1992 through November 1999. We consider 23 patients, 70 years old or older at the time of surgery. The following objective parameters were considered and compared with the younger population: length of stay in the hospital; mean preoperative stay; mean postoperative stay; incidence of risk factors; postoperative complications. A questionnaire was also mailed to all individual 427 patients. RESULTS: Length of stay in the hospital declined in both population, during the time interval considered. The incidence of risk factors, both major and minor, increases consistently with age from less than 1% below the age of 30 to about 62% in the eighth decade and over. Major postoperative complications were 4.34% in patients > or = 70 vs. 2.8% in patients < 70 years of age. Mortality was nil in both groups. Ninety percent reported complete disappearance of preoperative symptoms. CONCLUSIONS: Laparoscopic cholecystectomy in geriatric patients is safe and risks are reasonably low. Selection of patients must be done on strict indications.

[Preoperative staging of gastric carcinoma using endosonography (EUS)].

Accurate staging of gastric malignancy can only be obtained at surgery and after detailed histological examination of the resection specimen. Endoscopic ultrasonography may provide accurate detection and staging of gastric cancer because of its ability to visualize both the intramural and extramural extent of the lesion and any adjacent lymph node involvement. From february 90 to april 91, 29 patients with a gastric carcinoma were studied endosonographically before surgery. All studies were performed with an Olympus EU-M3. Preoperative TNM classification and a prediction of the resectability of gastric cancer were done in every patient. The results were matched with those obtained with the histology of resected specimens according to the TNM classification 1987. Endoscopic ultrasonography was accurate in assessing the extent and depth of tumor infiltration. The overall accuracy rate was 90.5% (19 out of 21 patients). Overstaging occurred in 9.5% of the cases (2 patients); none understaging occurred. EUS was less accurate in assessment of lymph node metastasis; the overall accuracy rate was 57.1%. Distinction between reactive lymph node and small micrometastatic lymph node involvement could be hard. Local resectability was correctly diagnosed with EUS in each of 23 patients; in two patients an intramural mass with a deep infiltration into the surrounding tissue was correctly diagnosed. In our opinion EUS is an essential diagnostic procedure in the clinical staging of the gastric cancer.

[Surgical options in the treatment of perianal Crohn's disease].

INTRODUCTION: About 40% of patients with Crohns disease (CD) have a perianal involvement. Despite the recent introduction of anti-TNF antibody, this therapy has uncertain long-term results and surgery still remains a major treatment option. AIMS & METHODS: This study relates our experience in surgical management of perianal CD without anti-TNF treatment. From July 92 to February 02, 37 patients with perianal Crohns disease were treated, 43 underwent local operations or faecal diversion for fistulas and/or abscesses. Patients not requiring surgery or in therapy with anti-TNF. were excluded from the study. We analysed the outcome of surgical treatment for perianal CD. RESULTS: Male to female ratio was 1:0.6, median age was 36,9 years (range 17-62). Perianal disease included 32 fistulas (16 trans-sphincteric, 2 superficial, 2 ano-vaginal, 10 multiple and complex, 2 horseshoe) and 7 abscesses (5 perianal, 2 ischio-rectal). Local surgery included 1 abscess drainage, 5 abscess drainage and fistula incision with seton insertion, 2 fistulotomy, 9 partial fistulectomy and seton insertion. At surgery, 40% of patients were ongoing a medical treatment with 5-ASA and/or antibiotics, 40% with steroids and/or immunosoppressors, 15% only with 5-ASA and 5% no ongoing treatment. The horseshoe fistulas were managed with a fistulotomy and seton insertion. One patient with ano-vaginal fistula required proctectomy and the other one total proctocolectomy. Patients treated by diverting colonostomy (3) had fistula recurrence after its closure in 100%. 20% of patients required total proctocolectomy and ileostomy for extensive intestinal disease. Of the 27 patients undergoing seton insertion or fistulotomy none had faecal incontinence due to the operation and 38% had a 1 year recurrence. CONCLUSIONS: Perianal CD is a heterogeneous entity, therefore its management is still controversial. Moreover, a high percentage of patients (18% in our series) requires a major surgery due to the extension and seriousness of rectal involvement. In our survey only 12 patients (39%), with trans-sphincteric fistula, could have been theoretically treated with anti-TNF. We wonder if the cost-and-benefit of this medical treatment justifies its application on patients that could undergo a surgical treatment with good long-term results.
