Factors influencing long-term survival in 100 cases of small intestine primary adenocarcinoma

BACKGROUND

Factors influencing long-term survival in patients undergoing operation for adenocarcinoma of the small intestine are poorly recognized.

METHODS

Retrospective study of 100 cases culled within a 10-year period by questionnaire, including 59 males and 41 females, median age 61 years (range 30 to 86). No patients were lost to follow-up (median 27 months). All patients underwent operation: curative in 65% and palliative in 35%.

RESULTS

Overall actuarial 5-year survival was 38%, 0% after palliative treatment and 54% after curative resection. In patients undergoing curative resection, 5-year survival was 63% when the lymph nodes were not involved, and 52% when they were; 57% when the serosa was not involved, and 53% when it was; 56% when the tumor was well or moderately well differentiated and 40% when it was undifferentiated. Other factors influencing long-term survival were the emergency setting, the site, the multiplicity, and the size of tumor (none with statistically significant differences). Five and 10-year survival was 78% and 69%, respectively, when the patient was anemic compared with 35% and 17%, respectively when the patient was not (P <0.01). There were 14 patients with previous carcinoma, 2 with Crohn's disease, and 1 each with celiac disease and ileal tuberculosis. There were also 8 patients with associated duodenal and proximal jejunal polyps. Thirteen patients sustained a total of 14 further cancers.

CONCLUSIONS

Patients should be followed up closely because the possibility of sustaining another abdominal carcinoma is high (16%). As associated polyps are nearly always duodenal or jejunal, preoperative or intraoperative endoscopy of the upper gastrointestinal tract including the initial portion of the jejunum should be able to detect their presence and reduce the risk of early recurrence.

Shouldice inguinal hernia repair in the male adult: the gold standard? A multicenter controlled trial in 1578 patients

BACKGROUND

Hernia repair is the second most frequently performed operation in France and in the United States, the prevalence being 36 for every 1000 males. Lowering the recurrence rate by 1% would mean 1000 fewer operations for hernia repair per year in France.

METHODS

Between 1983 and 1989, 1578 adult males with a total of 1706 nonrecurrent inguinal hernias were prospectively and randomly allotted to undergo either a Bassini's repair, Cooper's ligament, or Shouldice repair with polypropylene or a Shouldice repair with stainless steel for determination of which technique was associated with the lowest recurrence rate. Fifty-nine hernia repairs were withdrawn after inclusion. Of the 1647 remaining hernias, 52.2% were indirect, 25.6% were direct, and 23.2% were combined. Patients were seen every 6 months for 3 years and then every year. Median follow-up was 5 years 8 months (range, 3 months-8.5 years).

RESULTS

At 8.5 years, 5.6% of hernias were lost to follow-up. Ninety-seven hernia repairs failed, 50% during the first 2 years. The actuarial recurrence rate was 7.94% at 8.5 years. The Shouldice repair (stainless steel or polypropylene) was associated with fewer recurrences (6.1%) than either the Bassini's (8.6%) or Cooper's ligament repair (11.2%) technique (p < 0.001). This difference remained significant even when the maximal bias test was used. Fewer recurrences (5.9%) were observed with the stainless steel wire Shouldice repair than with polypropylene version (6.5%), but the difference was not significant.

CONCLUSIONS

Shouldice hernia repair provides the patient with the best chances of nonrecurrence regardless of the anatomical type of hernia. The Shouldice hernia repair should be the gold standard for inguinal hernia repair in men and serves as the basis for comparison with all other techniques, be they prosthetic or laparoscopic.
