[Clinical and functional results after restorative proctocolectomy with ileal J reservoir in the treatment of ulcerative colitis]. / Risultati clinici e funzionali dopo proctocolectomia restaurativa con serbatoio ileale a J nel trattamento della colite ulcerosa.

PURPOSE: Restorative proctocolectomy is the procedure of choice in the treatment of ulcerative colitis. The operation is successful in removing all diseased mucosa while preserving a normal bowel function and a good quality of life for the patient. In this article are presented the clinical and functional results obtained in 28 patients, 19 males (68%) and 9 females (32%) after stapled restorative proctocolectomy with ileal J pouch-anal anastomosis. RESULTS: There were no perioperative deaths. The overall morbidity rate was 31%. Six patients (21%) presented pelvic abscess; 2 (7%) pelvic hematoma, 4 patients (14%) ileo-anal anastomotic stricture, 1 patient (3.6%) pouch-vagina fistula, three patients (11%) intestinal obstruction and 7 (25%) pouchitis. All patients were able to evacuate their pouches spontaneously. The mean bowel movements were 6-9/24 hours at the first postoperative month and 3-5/24 hours at the sixth month. Infrequent nocturnal seepage occurred in 6 patients (21%). Stool consistency returned to normal within 3-6 months. The mean pouch capacity was 210 cc. The mean resting pressure was diminished in 11 patients (39%), the men and maximal squeeze pressures were improved in 9 (32%); the ileo-rectal-anal inhibitory reflex was normal in 5 patients (18%), not defined in 12 (43%). Impotence or impaired bladder function was not present. CONCLUSION: The use of staplers in the surgical technique of restorative proctocolectomy with J shaped ileo-anal pouch is associated with low morbidity and better long-term results. The procedure requires a good selection of patients, a correct surgical timing, a very carefully technique and a low pre and postoperative treatment with steroids.

[Aspects of the complications after restorative proctocolectomy in the treatment of ulcerative colitis. Review of the literature and personal experience]. / Aspetti delle complicanze dopo proctocolectomia restaurativa nel trattamento della colite ulcerosa. Revisione della letteratura ed esperienza personale.

PURPOSE: Analysis of complications and causes of failure after stapled restorative proctocolectomy with ileal J pouchanal anastomosis in patients with ulcerative colitis is presented. PATIENTS AND METHODS: The procedure was performed in 28 patients, 19 males (68%) and 9 females (32%); diverting ileostomy was always performed. RESULTS: There was no perioperative mortality. The overall morbidity rate was 31%. Six patients (21%) had pelvic abscess, 2 (7%) pelvic hematoma, 4 patients (14%) presented ileo-anal anastomotic stricture, 1 patient (3.6%) had pouch-vaginal fistula, three patients (11%) presented intestinal obstruction and 7 (25%) pouchitis. Reoperation was necessary in patients with small bowel obstruction and with pouch-vaginal fistula. Septic complications and pouchitis were resolved with medical treatment. Stenosis of the anastomosis required anal dilation. No patient underwent pouch excision for pouch failure. CONCLUSION: The main significant complications of ileal pouch-anal anastomosis for ulcerative colitis were pelvic sepsis, intestinal obstruction and pouchitis. Our results suggest that the use of stapling technique is safer and has fewer early septic complications and sepsis-related pouch removals. Success in ileo-anal construction increases with experience. The selection of patients with exclusion of Crohn disease, a correct surgical timing, a carefully technique, a delayed ileostomy closure and a low pre and postoperative regimen of steroids are important factors of success.

[Aneurysms of the visceral arteries: report of 5 cases]. / Gli aneurismi delle arterie viscerali: presentazione di cinque casi.

Visceral artery aneurysms are uncommon and usually result from atherosclerosis, periarteritis nodosa and fibromuscular dysplasia. Hepatic artery aneurysms were detected in two patient, splenic artery aneurysms in three. In four patients rupture occurred. In the two patients with hepatic artery aneurysm hemobilia from arterial rupture into the common bile duct and intraperitoneal bleeding in lesser sac was assessed. Ruptured aneurysms of the splenic artery with free intraperitoneal bleeding occurred in two patients, one patient had an asymptomatic splenic artery aneurysm. In four patients the diagnosis was made by contrast-TC and/or celiac and mesenteric angiography. In four patients excision of the aneurysm was successfully performed. One patient with ruptured hepatic artery aneurysm and in which resection and revascularization was made died.

[Short bowel syndrome: etiologic, pathogenetic aspects and principles of treatment]. / La sindrome da intestino corto: considerazioni etio-patogenetiche e principi di trattamento.

A significant problem in surgery following massive intestinal resection is the short bowel syndrome characterized by severe fluid and electrolyte loss, watery diarrhoea and malnutrition. Total parenteral nutrition and enteral nutrition are essential in the clinical course of the syndrome; their use for prolonged periods results in the gradual intestinal adaptation and greater absorptive and reservoir capacities of the intestinal remnant. Adjunctive surgery can slow rapid intestinal transit and induce growth of neo-small-bowel mucosa but is not recommended for routine use. The early results of intestinal transplantation in the treatment of short bowel syndrome are encouraging. Furthermore chronic rejection and systemic sepsis with failure of the graft must be considered and indicate that at present this procedure cannot be offered to every patient but will be a potential form of therapy in future.

[Familial adenomatous polyposis. Problems encountered with rectum preservation in surgical treatment and life expectancy]. / La poliposi adenomatosa familiare. Problemi offerti dalla conservazione del retto nel trattamento chirurgico ed aspettative di vita.

Familial adenomatous polyposis is a genetically inherited disease with very high risk of colorectal cancer and with a large expression of multiple extracolonic malignancies. In recent years two surgical options are available for the treatment of FAP: total colectomy with ileorectal anastomosis and restorative proctocolectomy with ileoanal reservoir. The preservation of the rectum offers good quality of life and good functional results, but needs an accurate surveillance of the rectal stump and screening for the development of cancer. Restorative proctocolectomy is reserved for patients with large or confluent polyps of the rectum, for older patients and for those who had already had an ileorectal anastomosis and who develops subsequently large adenomas at increased risk for rectal cancer. Prophylactic procedures of surveillance, screening and surgery have reduced in patients at risk the incidence of colorectal cancer. But recently an increased number of malignant extracolonic tumors (gastric cancer, duodenal and periampullary cancer, small intestinal cancer, adrenal and thyroid cancer) and abdominal desmoid tumors, that causes a significant mortality, has been documented. The knowledge of the extracolonic features of FAP suggests a careful follow-up of the patients and the prevention and treatment of upper gastrointestinal cancers and desmoid disease.

[Use of a gonadoliberin agonist with or without gonadoliberin pulses for ovulation induction in ovarian dystrophies]. / Utilisation d'un agoniste de la gonadolibérine suivie ou non de gonadolibérine pulsatile pour l'induction d'ovulation dans les dystrophies ovariennes.

OBJECTIVES: Determine whether ovulation in dystrophic ovaries treated with GnRH agonist followed by GnRH pulses is due to the GnRH pulse or is patient-dependent. SITE. Endocrinology department, CHU Purpan, Toulouse, France. METHODS: Fifteen infertile patients, age range 22 to 35 years, with ovarian dystrophy were given GnRH agonist (Decapeptyl, 3.75 mg IM on day 3 of the cycle). In 5 patients, an IV pulse of GnRH was then given (6 micrograms/90 min). STATISTICAL ANALYSIS: Mann-Whitney U test, corrected chi 2 test. RESULTS: Ovulation was achieved in 8/15 cases (3/5 with and 5/10 without pulsatile GnRH p = NS) and 3 pregnancies (without pulsatile GnRH). Before treatment LH was higher in patients who had an ovulation. CONCLUSION: Ovulation can be achieved after GnRH agonist treatment in patients with dystrophic ovaries, with or without pulsatile GnRH, particularly if the initial LH levels are high.

[Massive hemorrhage caused by colonic diverticulosis]. / L'emorragia massiva da diverticolosi colica.

Massive hemorrhage from diverticular disease of the colon is a very difficult problem in abdominal emergency surgery. The pathogenesis of bleeding colonic diverticulosis is strictly correlated to the angioarchitecture of the colonic diverticular wall. Here the vasa recta penetrate the colonic wall from the serosa to the submucosa through connective tissue septa. Injurious factors arising from the colonic or diverticular lumen can produce an eccentric damage to the luminal side with intimal thickening, segmental weakening of the artery and its rupture with massive bleeding. Conventional barium enema is not able to show the source of the hemorrhage in the majority of the bleeding patients; colonoscopy, as primary emergency procedure, has significant positive findings in 41.5%-83.7% of patients. Radionuclide bleeding scans have a sensitivity rate of 86%-94%. Emergency arteriography localizes the bleeding source in higher rates ranging from 58% to 86% and is successful after intraarterial infusion of vasopressin or embolization in 47%-92% of patients. Surgical treatment for continued bleeding from diverticular disease is controversy. Segmental resection should be performed on patients with localized bleeding sources (positive arteriogram). Laparotomy, anterograde irrigation and intraoperative colonoscopy are indicated in patients with multiple bleeding sites and negative arteriography. Because the right colon is the most common site of bleeding in same cases is necessary to perform a subtotal colectomy with ileorectal anastomosis. Blind resections particularly in the elderly patients present high rebleeding rate (> 60%) and high mortality (30%) with sepsis accounting for the majority of deaths.

[Large abdominal incisional hernias, use of prosthesis. Our experience]. / Considerazioni sui grandi laparoceli addominali, l'utilizzo di protesi. La nostra esperienza.

Retrospective analysis of risk-factors in 241 patients with large abdominal incisional hernia collected in a 16-year period at the Department of Surgery, University of Pavia, allows the Authors to identify the aetiological mechanism of herniation and to discuss the fundamental technical skills in wall reconstruction. The recurrence rate after primary repair was 30% (63/209 patients). In 32 patients (13.3%) plastic prosthesis was used. The side of recurrent herniation was upper midline in 12 patients (37.5%), lower midline in 6 patients (19%), right lower quadrant in 8 patients (25%), right and left flank in 4 (12.5%) and in 2 patients (6.25%) respectively. Plastic repair was performed with a polytetrafluoroethylene graft (PTFE) in 19 patients (59%), with a polypropylene mesh in 7 patients (22%); woven polyethylene mesh was used in 6 patients (19%). Recurrence after prosthetic repair was seen in 5/32 patients (15.6%) and was correlated to local sepsis in patients with poor nutritional status. The PTFE mesh was considered useful to reduce the recurrence rate of hernias and the postoperative disability. It was associated with good elasticity, adequate strength, satisfactory tissue acceptance and minimal risk of infection. However the best results need a careful preoperative evaluation, no tension on the suture line, the prevention and properly treatment of postoperative complications.

Analysis of recurrence following curative low anterior resection and stapled anastomoses for carcinoma of the middle third and lower rectum.

In a series of 93 patients with middle and lower rectal cancer, who underwent potentially curative surgery by low anterior resection (LAR) with EEA stapled anastomosis or by abdominoperineal excision (APE) between January 1977 and December 1981, the incidence of recurrence and survival rate was compared. LAR with stapler was performed in 61 patients: 55 (90.2 percent) with tumors of the middle third and six (9.8 percent) for tumors of the lower third of the rectum. APE was performed in 32 patients: 13 (40.6 percent) with cancer of the midrectum and 19 (59.4 percent) of the lower rectum. Tumor site, Dukes' distribution, grade of malignancy, and extent of local spread were recorded. The tumor stages for LAR with stapler and for APE, respectively, were Dukes' A 7/1; Dukes' B 27/10; Dukes' C 25/18; Dukes' D 2/3. In a follow-up period of four years (range, 6 to 52 months) the overall recurrence rates were 20.4 percent in the LAR with stapled anastomosis group and 21 percent in the APE group. Local recurrence percentages were 9.8 percent after LAR and 14 percent after APE (P = N.S.). Distant recurrences were 12 percent and 14 percent, respectively. The four-year overall survival rates were 76.7 percent after LAR and 65.5 percent after APE (P = N.S.) The clinical and pathologic factors correlated with recurrence in low rectal carcinoma were reanalyzed and the controversial points of the surgical management for and against LAR with stapled anastomosis and APE were discussed. It is concluded that LAR with the EEA stapler can be carried out in the middle and lower rectum with the prospect of ultimate cure, when performed with proper technical skills in selected patients.

[Treatment with LH-RH in female sterility]. / Traitement par le LH-RH dans les stérilités féminines.

The discovery that LH/RH was secreted in a pulsatile manner has made it possible to use the substance therapeutically in certain endocrine conditions of female sterility. 29 patients had sterility because of ovarian dysfunction. 3 of these were polycystic ovaries, 13 unexplained malfunction of ovulation and 30 hypothalamic in cause. They were treated with LH/RH intravenously. The dose used with each pulse was 6-18 micrograms. The patients were treated for between 18 and 30 days. In the 9 pregnancies that occurred (30%) one was in a patient with polycystic ovaries, 8 (70%) were in patients with hypothalamic ovarian failure. In each case the dose of LH/RH had been administered either at a level of less than 10 micrograms/pulse throughout the follicular phase with an injection of 5000 IU of HCG after ovulation or throughout the whole cycle. 77% of the pregnancies were obtained during the two first cycles of treatment. This work shows that hypothalamic female sterility is the proper indication for treatment using LH/RH. The protocol of dosage should be as economical as possible by administering 5-10 micrograms pulses intravenously up to the time that ovulation has been achieved. This takes note of the difficulties of obtaining supplies of the substance.
