Risk of residual rectal mucosa after proctocolectomy and ileal pouch-anal reconstruction with the double-stapling technique. Postoperative endoscopic follow-up study.

PURPOSE: This study was designed to assess the risk of retained rectal mucosa after proctocolectomy and ileal pouch-anal anastomosis with the double-stapling technique. METHODS: A total of 113 patients underwent proctocolectomy with an ileal pouch-anal reconstruction. In 57 patients the anastomosis between pouch and proximal anal canal was performed using the double-stapling technique. In 26 patients the procedure was carried out without a protecting ileostomy. Of the remaining 31 patients with a proximal ileostomy, 15 underwent endoscopy six weeks postoperatively. Circular biopsies were taken just distal from the pouch-anal anastomosis. RESULTS: Histologic examination revealed rectal mucosa in at least one biopsy in 7 of 15 patients. At follow-up (mean 18 months) no (distal) pouchitis was clinically noticed. In one patient with familial polyposis, a few polyps, distal of the anastomosis, had to be endoscopically removed. CONCLUSIONS: Double-stapled ileal pouch-anal anastomosis has a considerable risk of residual rectal mucosa, because of combined linear transection and circular stapling with bilateral dog-ear formation of rectal mucosa. Residual rectal mucosa did not seem to influence clinical results at follow-up.

Delayed postoperative emptying after esophageal resection is dependent on the size of the gastric substitute.

BACKGROUND: Delayed emptying of the gastric substitute is a common problem after resection and reconstruction of the esophagus. The occurrence of postoperative delayed gastric emptying in patients undergoing resection and reconstruction of the esophagus was studied with regard to the type and size of gastric substitute and the execution of a pyloroplasty. STUDY DESIGN: From 1983 to 1994, one hundred fifty-five patients underwent resection of the esophagus, with a hospital mortality rate of 7 percent. The inability to resume a diet of solid food within one week after a normal esophagography was defined as delayed gastric emptying. One hundred forty patients were studied; group 1, substitution with whole stomach with (1a, n = 9) and without (1b, n = 31) pyloroplasty; group 2, substitution with distal two-thirds stomach with (2a, n = 20) or without (2b, n = 45) pyloroplasty; and group 3, tubulized stomach without pyloroplasty (n = 35). RESULTS: Delayed gastric emptying was seen in 38 percent (15 of 40) of patients in group 1 (1a, 44 percent; 1b, 37 percent), in 14 percent (nine of 65) of patients in group 2 (1a, 10 percent; 2b, 15 percent), and in 3 percent (one of 35) of patients in group 3. The differences between patients in group 1 and group 2, and between patients in group 1 and group 3 were significantly different (p < 0.05). CONCLUSIONS: The type of gastric remnant used for reconstruction is an important determinant of postoperative gastric emptying. Pyloroplasty does not prevent delayed gastric emptying after esophageal substitution.

[Surgical treatment of anorectal disorders in 32 HIV-seropositive patients].

OBJECTIVE: To describe the presentation and surgical treatment of anorectal pathology in HIV seropositive patients. DESIGN: Retrospective study. SETTING: Department of surgery, University Medical Centre, Amsterdam, the Netherlands. METHODS: Retrospective review of the records of 32 HIV seropositive patients surgically treated for anorectal pathology in 1985-1992. RESULTS: The 32 patients, homosexual males, had a total of 46 diagnoses for which they underwent 49 surgical interventions. Sixteen patients had an anorectal ulcer (14 in the anal canal, 2 in the distal rectum); 7 were treated by local excision and 9 with additional advancement of the anal mucosa; there were 4 and 2 recurrences, respectively. Ten patients had a perianal abscess; 5 a fistula, 2 of whom initially presented with a metastatic abscess in liver and brain. Eight patients had perianal warts, which in 2 cases showed severe dysplasia and in one an infiltrating carcinoma. Five patients presented primarily with a malignancy (3 with squamous cell carcinoma of the anus, 1 with cloacogenic carcinoma, 1 with non-Hodgkin lymphoma distally in the rectum). Twelve patients died within 6 months after the first operation. CONCLUSION: In choosing therapy for anorectal disorders, the limited survival of HIV seropositive patients, especially those with an advanced stage of AIDS should be considered. Surgical treatment can improve the quality of life in these patients.

Dermal angiosarcoma of the breast: a complication of primary radiotherapy?

A 70-year-old female developed recurrent disease following radiotherapy for primary inoperable breast cancer 5.5 years previously. Salvage mastectomy was performed. Pathology revealed recurrent breast cancer, along with a second primary malignancy, a dermal angiosarcoma. Radical excision of recurrent angiosarcoma failed. Irradiation combined with hyperthermia showed good palliation. The angiosarcoma's possible relation to the initial radiotherapy is discussed.

What happens to the rectal muscular cuff? An experimental study in dogs.

The anatomy and histology of the rectal muscular cuff was studied in 15 dogs with an ileal pouch-anal anastomosis. Eight channel, three-dimensional anal manometry showed normal maximal squeeze pressure (128 +/- 20 mm Hg) compared to a control group (135 +/- 4 mm Hg). The rectal muscular cuff showed complete absence of the cuff in three cases. In 12 dogs, the rectal cuff was retracted to a length of less than 1 cm, the muscle fibers were degenerated and fibrotic. The results in the canine model and the clinical results of patients with an ileal pouch-anal anastomosis with a cuff demonstrated that a rectal muscular cuff is not essential to maintain continence after ileal pouch-anal anastomosis.

High-vacuum drainage and primary perineal wound closure in abdominoperineal excision of the rectum.

The result of perineal wound healing after rectal excision with primary perineal closure by high-vacuum drainage was studied prospectively. High vacuum drainage was performed via a wide-bore catheter (Ch. 27) placed through a stabwound on the thigh. The method was applied in 114 of 127 patients who had abdominoperineal excision of the rectum (89.7 per cent). Contra-indications were inadequate haemostasis and pre-existing massive perineal sepsis. Primary perineal wound closure was present in 85.9 per cent of patients, delayed healing in 12.3 per cent and a perineal sinus developed in two patients (1.8 per cent).

Leiomyosarcoma of large and small veins: clinical findings and results of treatment in six patients.

Vascular leiomyosarcomas are rare malignant tumours originating from the media of the vessel wall. Six patients (five women and one man, aged 44-66 years) have been treated for a vascular leiomyosarcoma located in the inferior vena cava (three patients), the suprarenal, the external iliac and an antecubital vein. In four patients, the tumour was large and extended beyond the vessel wall giving rise to a retroperitoneal mass. In two patients the tumour was confined to the inner wall of respectively a large and small vein, occluding the lumen; the former was in the inferior vena cava and the latter in an antecubital vein. Block resection was performed in all patients. The tumours showed mitotic indices ranging from 6-32 mitoses/10 high power fields. The five patients with retroperitoneal tumours received additional radiotherapy varying from 50.00-70.00 Gy, on the basis of either macroscopic residual tumour or indefinite radicality. One of these five patients developed distant metastases within 2.5 years without local recurrence, the other four had no evidence of recurrence at follow-up, 3-7 years (mean 4.2 years) after surgery. The results illustrate the role of adjuvant radiotherapy in the control of local recurrence, when resection in this type of tumour proves to be either non-radical or totally radical.

[Ileo-anal anastomosis with ileum reservoir].

Ileo-anal anastomosis with an ileal pouch is a reasonable alternative for patients with ulcerative colitis and adenomatous polyposis coli. The type of the reservoir, the length of the rectal cuff and the level of the anastomosis are still topics of discussion. This operation was performed in 41 patients. A modified J-reservoir (B-reservoir) was constructed in 34 patients in an attempt to improve the function of the neorectum. Twenty patients underwent inter-sphincteric freeing of the rectum and subsequent resection without leaving a rectal cuff. Although this procedure is associated with a considerable morbidity, the ultimate result is satisfactory.

Immunocytochemical study of endocrine cells in pelvic ileal reservoirs.

The distribution and morphology of intestinal endocrine cells was investigated in the mucosa of pelvic ileal reservoirs using immunocytochemical methods. Endoscopic biopsies were obtained from 15 patients after the construction of a modified J-pouch. The mucosa of the reservoir showed a variable degree of colonic metaplasia in all cases. No relevant quantitative variations of gut endocrine cells were detected, as revealed by immunostaining for the general marker, chromogranin, compared with normal ileal mucosa. Immunostaining for different peptide-containing cells resulted in normal number and morphology of serotonin, enteroglucagon, peptide tyrosine-tyrosine, and somatostatin-containing cells. Neurotensin cells were less numerous than in normal mucosa. The role played by gastrointestinal hormones in the adaptive response of the intestine to pouch construction is, presently, unclear. Further studies involving measurements of fasting and meal-stimulated levels of gut hormones in pouch patients might clarify this aspect.

Spontaneous rupture of the oesophagus.

Spontaneous rupture of the oesophagus or Boerhaave syndrome is a rare phenomenon which poses a surgical challenge. Without treatment a mortality has been reported of up to 100 per cent. Early diagnosis and treatment are therefore imperative. An aggressive surgical approach is described. Three patients were treated with good results by closure of the rupture, drainage of the mediastinum, a diverting oesophagostomy, gastric drainage and postoperative enteral feeding via a jejunal catheter.

[Periampullary carcinoma as a second primary tumor following a previously treated adenocarcinoma of the colon].

Three patients are presented who developed periampullary carcinoma after colectomy for adenocarcinoma. The combination of colonic carcinoma and periampullary carcinoma is rare, although wellknown in patients with colonic polyposis or Gardner's syndrome. Perhaps genetic research might help select patients with a high risk of developing multiple carcinomas in the gastrointestinal tract. The five-year survival rate for periampullary carcinoma after subtotal colectomy is higher than for pancreatic carcinoma.

Ileal pouch-anal anastomosis without rectal muscular cuff.

Twenty patients underwent proctocolectomy followed by an ileal pouch-anal anastomosis. The rectum was mobilized in the intersphincteric plane and transected at the level of the dentate line. As a consequence, a rectal cuff, which is considered by some to be important for the maintenance of anal continence, was not left behind. All patients were continent. Manometric data demonstrated no difference compared to a group of 21 patients with a conventional mucosectomy. Nearly half of the patients in both groups had a positive recto-anal inhibitory reflex. As a rectal cuff is not essential for maintaining continence, the receptors of the rectoanal inhibitory reflex are probably located outside the rectal wall.

Long-term follow-up after colectomy and ileorectal anastomosis in familial adenomatous polyposis coli. Is there still a place for the procedure?

Forty-four patients with familial adenomatous polyposis coli treated with colectomy and ileorectal anastomosis were studied. Mean age at operation was 27 years. The mean follow-up period was 10 years (median 8 years). Three patients (7%) developed rectal cancer 1, 4, and 24 years after the initial operation, respectively. Proctectomy with ileostomy was performed in one patient, and 7 patients underwent a conversion to an ileoanal procedure for an increasing number of rectal polyps in the rectum stump. Although frequent bowel actions and episodes of diarrhea were common findings in patients after colectomy and ileorectal anastomosis, almost all patients (96%) were more or less satisfied with their quality of life after the procedure. On the basis of our results and the results reported in the literature, colectomy with ileorectal anastomosis is still the operation of choice in selected patients with familial adenomatous polyposis coli. An initial ileal pouch - anal anastomosis, or a conversion to such a procedure after colectomy and ileorectal anastomosis is indicated, depending on the number and size of rectal polyps.
