The ileoanal pouch procedure in the long-term perspective: a critical review.

An ileo-pouch anal anastomosis (IPAA) has become the gold standard procedure for ulcerative colitis and familial adenomatous polyposis. Clinical results on the pelvic pouch procedure have often been encouraging; when confronted with the different surgical options, the majority of patients select IPAA as the best operation. However, even if IPAA is a great innovation, it is by no means the first choice for all patients. For patients old enough to join in a responsible discussion, the pros and cons of the various operations must be carefully described; the choice of surgical procedure must meet the patient's wishes and appear soundly based to the surgeon. The young age of most patients has to be considered and a long follow-up time is required to establish whether and, if so, to what extent the operation may adversely impact the patient's continence, sex life, fertility, and quality of life. The risk of cancer transformation in the residual rectal mucosa in the muscular or columnar cuff is another important factor that may influence the eventual decision. This article critically reviews our experience and the literature.

Is an ileal pouch an alternative for patients requiring surgery for Crohn's proctocolitis?

BACKGROUND: Most surgeons consider Crohn's colitis to be an absolute contraindication for a continent ileostomy, due to high complication and failure rates. This opinion may, however, be erroneous. The results may appear poor when compared with those after pouch surgery in patients with ulcerative colitis (UC), but the matter may well appear in a different light if the pouch patients are compared with Crohn's colitis patients who have had a proctocolectomy and a conventional ileostomy. METHODS: We assessed the long-term outcomes in a series of patients with Crohn's colitis who had a proctocolectomy and a continent ileostomy (59 patients) or a conventional ileostomy (57 patients). The median follow-up time was 24 years for the first group and 27 years for the second group. RESULTS: The outcomes in the two groups of patients were largely similar regarding both mortality and morbidity; the rates of recurrent disease and reoperation with loss of small bowel were also similar between groups. CONCLUSIONS: The possibility of having a continent ileostomy, thereby avoiding a conventional ileostomy-even if only for a limited number of years--may be an attractive option for young, highly motivated patients.

Injection treatment of hemorrhoids in patients with acquired immunodeficiency syndrome.

PURPOSE: Patients with acquired immunodeficiency syndrome are often in poor general physical condition. Diarrhea and bleeding hemorrhoids frequently contribute to the morbidity, and patients with such problems cause an increasing load on many outpatient clinics. METHODS: Twenty-two patients (17 males) with acquired immunodeficiency syndrome had injection treatment for bleeding second-degree to fourth-degree hemorrhoids according to standard outpatient clinic routines. Mean follow-up was 24 months. RESULTS: No complications were recorded. The treatment was successful in all patients, and no hemorrhoidectomy was necessary. Nineteen patients improved after their first injection, whereas 3 patients required two to six weeks repeated treatments to improve. Four subjects with the longer follow-up (4 years) showed an improvement lasting 12 to 18 months and then required one to two treatments per year to stop recurrent bleeding. CONCLUSIONS: Because of their poor general condition and poor wound healing, a conservative approach is preferable to avoid a formal hemorrhoidectomy in patients with acquired immunodeficiency syndrome. Sclerotherapy seems to be an attractive alternative.

[The functional and manometric results of 2 surgical methods of posterior abdominal rectopexy].

Functional changes after posterior abdominal rectopexy for the treatment of rectal prolapse are not fully understood. We studied the effects of Wells' or Ripstein's rectopexy on functional characteristics as related to anal sphincter function, rectal volume and sensory function in 31 patients with complete or internal rectal prolapse. We have observed an improvement of continence over 70% in both groups. However, an absent or a decreased call to stool, constipation and evacuation difficulties are the aftermath of Wells' rectopexy, while these complaints appear basically unaffected by Ripstein's technique. Maximal squeeze pressure was slightly increased after Ripstein's rectopexy, whereas no significant effects were found on anal pressures. Postoperatively the rectal capacity was reduced by Well's procedure (p < 0.05), while no significant changes were observed with Ripstein's operation. After the Wells procedure patients developed at the threshold for the relaxation of the internal sphincter progressively lower rectal volumes, reaching one year after rectopexy the statistical significance. Sensory thresholds for sense of filling and urge were significantly raised after Wells' rectopexy even one year after operation, whereas after Ripstein's operation sense of filling was not significantly affected and while sense of urge was increased early postoperatively, it was not significantly changed at one hear postoperative control. In conclusion, when fecal incontinence appears associated to a rectal prolapse has good chances to improve postoperatively. Preoperative evacuation difficulties seem to be unaffected by a posterior abdominal rectopexy, Wells or Ripstein, but an extensive dissection of the rectum with the division of the lateral stalks, as it is performed in Wells' operation, seems to be a procedure that can create a further burden of problems the the patient and it seems coupled to a manovolumetric elevation of rectal sensory thresholds.

[Repeated liver resections for metastases from colorectal carcinoma: the experience of 23 cases].

One hundred and thirteen patients with metastases from colorectal carcinoma underwent liver resection. The authors report their experience with respect to 23 repeated hepatic resections (or metastases from colorectal carcinoma). The calculated actuarial survival from the first operations is 100% at 12 months, 67% at 24 months, 48% at 36 months and 26% at 60 months. In 90 patients who underwent a single liver resection during the same period, 76% were alive at 12 months, 40% at 24 months, 27% at 36 months and 14% at 60 months (p = 0.03). Survivals calculated from the second operation were 67% at 12 months, 41% at 24 months and 11% at 35 months. There was no operative mortality with morbidity added to that of the first operation. None patients had extrahepatic disease at the second operation: this was resected. Seven patients were treated with neo adjuvant chemotherapy; six with systemic adjuvant chemotherapy; in one this was associated with loco-regional chemotherapy. The number of lesions (single versus multiple), the presence or absence of extrahepatic disease, neo-adjuvant chemotherapy and adjuvant chemotherapy did not seem to influence the prognosis. Average survival calculated from the appearance of the first metastasis in the liver is better in patients with a synchronous lesion compared to the patients with a metachronous lesion (48.1 months versus 29.3). The authors claim that surgery is indicated, when technically possible, in the hepatic recurrence of disease. The results are not as good as those obtained following the first liver resection, with a probability of earlier recurrence of disease.(ABSTRACT TRUNCATED AT 250 WORDS)

[Spontaneous rupture of the esophagus (presentation of a case)].

The authors describe the case of a 67-year-old patient with spontaneous rupture of the middle third of the oesophagus, occurring apparently without any involvement of intraluminal hypertension. The surgical treatment consisted in the execution of an aspiration drainage of the left pleural cavity, followed by a right thoracotomy with exploration of the mediastinum. A gastrostomy according to Witzel was also performed. Total parenteral nutrition was instituted in the post-operative period. Healing of the oesophageal lesion was confirmed radiologically 2 months after admission to our department.

Bronchopulmonary carcinoids: report of nine surgically treated cases.

Nine cases of bronchial carcinoids treated by surgery are reported. Six of them were females and three males. Their ages ranged from 37 to 68 years (median 52.8 years). Lobectomy was carried out in four instances (bilobectomy in one) and pneumonectomy in three. Based on preoperative histology two conservative operations were performed: one patient underwent segmental resection of the right upper lobe for a peripheral carcinoid and the other sleeve resection of the bronchus. The operations were complicated only in one case in which a broncho-pleural fistula appeared postoperatively and was successfully treated by thorachoplasty. There was no postoperative death. The only patient with an atypical carcinoid died one year after pneumonectomy. The other eight patients, with typical carcinoids are alive and without recurrent disease at 6 months to 8 years from surgery. Lymph node and parenchymal infiltration, observed in 3 patients, were not fatal. It is concluded that carcinoids should now be considered malignancies; typical carcinoids carry a more favorable prognosis than atypical ones and can be managed by conservative operations without affecting the survival rate. The spreading of the tumor to lymph nodes and surrounding tissues was not associated with an increased mortality in the reported cases.

[Malignant schwannoma of the ileum: an extremely rare disease entity (presentation of a case and review of the literature)].

The authors examine a case of malignant ileal schwannoma successfully treated in the Verona Surgical Clinic. They compare their experience with the data reported in the literature, confirming the extreme difficulty encountered in diagnosing the disease. Therapy is discussed, and the authors stress that, in the presence of an intestinal haemorrhage the origin of which traditional diagnostic investigations are unable to establish, one should always bear in mind the possibility of schwannoma despite its rarity.

[Surgical treatment of malignant colorectal neoplasms in the population over (our experience)].

The Authors examine a series of 95 operations in the Verona Surgical Clinic for colorectal carcinoma in patients aged above 75 and discuss the results obtained. The low mortality rate (2.95% for resections) and the acceptable incidence of morbidity confirm the validity of performing radical surgery for malignancies in very elderly patients, as is stressed in most of the relevant literature.

[Colonic hemorrhage caused by vascular dysplasia. Surgical treatment].

On the basis of their own clinical experience and the data provided in the literature, the authors examine the question of the surgical therapy of the two main dysplastic diseases of the colon, i.e. colonic angiodysplasia and angiomatosis. While the larger cavernous angiomas necessarily call for surgery, large-bowel angiodysplasia and capillary angiomas, which are disease falling primarily within the internist's sphere of competence, may be treated conservatively, when symptomatic, by endoscopic electrocoagulation, though a surgical approach may be contemplated in that small percentage of cases presenting coagulopathy or frequent, intense haemorrhages with a severe anaemic tendency.

[Our experience in the surgical treatment of diverticular disease (I: Election)].

The authors review their patient population with regard to the surgical treatment of diverticular disease. This population consists of 76 cases, 30 of which were subjected to elective surgery. They conclude by stating that, in the light of their experience, the most effective elective operation is resection of the tract affected by diverticuli followed by and end-to-end anastomosis with the protection of a decompressive transversostomy.

[Synchronous abdomino-perineal amputation (global evaluation of the intervention in our experience)].

In the light of their experience, the Authors examine the validity of synchronous abdomino-perineal resection. Their study population consists of 224 such operations. On the basis of the results achieved, the conclusion is reached that there is still no realistic alternative today to synchronous abdomino-perineal resection for the treatment of malignancies whose lower borders lie at a distance of less than 6.5 cm from the anal margin.

[Primary lymphoma of the breast (apropos of a clinical case)].

Taking as their starting point the observation of a case of primary lymphoma of the breast, the Authors point out that this tumour constitutes a rare disease in the context of non-Hodgkin lymphomas arising in sites other than the lymph nodes. They emphasize the clinical and instrumental diagnostic difficulties which the disease poses, as well as the uselessness of radical surgical therapy and the need for radio-chemotherapeutic management along with periodic follow-up. The Authors go on to explain how difficult it is to formulate a reliable prognosis for this type of tumour in view of the lack of homogeneity and the limited numbers of cases reported in the literature.
