- Objective: To analyze reoperation rates for recurrent and primary groin hernia repair documented in the Swedish Hernia Register from 1996 to 1998, and to study variables associated with increased or decreased relative risks for reoperation after recurrent hernia.Methods: Data were retrieved for all groin hernia repairs prospectively recorded in the Swedish Hernia register from 1996 to 1998. Actuarial analysis adjusted for patients' death was used for calculating the cumulative incidence of reoperation. Relative risk for reoperation was estimated using the Cox proportional hazards model.Results: From 1996 to 1998, 17,985 groin hernia operations were recorded in the Swedish Hernia Register, 15% for recurrent hernia and 85% for primary hernia. At 24 months the risk for having had a reoperation was 4.6% after recurrent hernia repair and 1.7% after primary hernia repair. The relative risk for reoperation was significantly lower for laparoscopic methods and for anterior tension-free repair than for other techniques. Postoperative complications and direct hernia were associated with an increased relative risk for reoperation. Day-case surgery and local infiltration anesthesia were used less frequently for recurrent hernia than for primary hernia.Conclusions: Recurrent groin hernia still constitutes a significant quantitative problem for the surgical community. This study supports the use of mesh by laparoscopy or anterior tension-free repair for recurrent hernia operations.

- Objectives: To compare a colonic J-pouch or a side-to-end anastomosis after low-anterior resection for rectal cancer with regard to functional and surgical outcome.Summary beckground data: A complication after restorative rectal surgery with a straight anastomosis is low-anterior resection syndrome with a postoperatively deteriorated anorectal function. The colonic J-reservoir is sometimes used with the purpose of reducing these symptoms. An alternative method is to use a simple side-to-end anastomosis.Methods: One-hundred patients with rectal cancer undergoing total mesorectal excision and colo-anal anastomosis were randomized to receive either a colonic pouch or a side-to-end anastomosis using the descending colon. Surgical results and complications were recorded. Patients were followed with a functional evaluation at 6 and 12 months postoperatively.Results: Fifty patients were randomized to each group. Patient characteristics in both groups were very similar regarding age, gender, tumor level, and Dukes' stages. A large proportion of the patients received short-term preoperative radiotherapy (78%). There was no significant difference in surgical outcome between the 2 techniques with respect to anastomotic height (4 cm), perioperative blood loss (500 ml), hospital stay (11 days), postoperative complications, reoperations or pelvic sepsis rates. Comparing functional results in the 2 study groups, only the ability to evacuate the bowel in <15 minutes at 6 months reached a significant difference in favor of the pouch procedure.Conclusions: The data from this study show that either a colonic J-pouch or a side-to-end anastomosis performed on the descending colon in low-anterior resection with total mesorectal excision are methods that can be used with similar expected functional and surgical results.

- OBJECTIVE: The aim of this randomized multicenter trial was to assess the rate of symptomatic anastomotic leakage in patients operated on with low anterior resection for rectal cancer and who were intraoperatively randomized to a defunctioning stoma or not. SUMMARY BACKGROUND DATA: The introduction of total mesorectal excision surgery as the surgical technique of choice for carcinoma in the lower and mid rectum has led to decreased local recurrence and improved oncological results. Despite these advances, perioperative morbidity remains a major issue, and the most feared complication is symptomatic anastomotic leakage. The role of the defunctioning stoma in regard to anastomotic leakage is controversial and has not been assessed in any randomized trial of sufficient size. METHODS: From December 1999 to June 2005, a total of 234 patients were randomized to a defunctioning loop stoma or no loop stoma. Loop ileostomy or loop transverse colostomy was at the choice of the surgeon. Inclusion criteria for randomization were expected survival >6 months, informed consent, anastomosis ≤7 cm above the anal verge, negative air leakage test, intact anastomotic rings, and absence of major intraoperative adverse events. RESULTS: The overall rate of symptomatic leakage was 19.2% (45 of 234). Patients randomized to a defunctioning stoma (n = 116) had leakage in 10.3% (12 of 116) and those without stoma (n = 118) in 28.0% (33 of 118) (odds ratio = 3.4, 95% confidence interval, 1.6-6.9, P < 0.001). The need for urgent abdominal reoperation was 8.6% (10 of 116) in those randomized to stoma and 25.4% (30 of 118) in those without (P < 0.001). After a follow-up of median 42 months (range, 6-72 months), 13.8% (16 of 116) of the initially defunctioned patients still had a stoma of any kind, compared with 16.9% (20 of 118) those not defunctioned (not significant). The 30-day mortality after anterior resection was 0.4% (1 of 234) and after elective reversal a defunctioning stoma 0.9% (1 of 111). Median age was 68 years (range, 32-86 years), 45.3% (106 of 234) were females, 79.1% (185 of 234) had preoperative radiotherapy, the level of anastomosis was median 5 cm, and intraoperative blood loss 550 mL, without differences between the groups. CONCLUSION: Defunctioning loop stoma decreased the rate of symptomatic anastomotic leakage and is therefore recommended in low anterior resection for rectal cancer.

- Objective: To analyze mortality following groin hernia operations.Summary Background Data: It is well known that the incidence of groin hernia in men exceeds the incidence in women by a factor of 10. However, gender differences in mortality following groin hernia surgery have not been explored in detail.Methods: The study comprises all patients 15 years or older who underwent groin hernia repair between January 1, 1992 and December 31, 2005 at units participating in the Swedish Hernia Register (SHR). Postoperative mortality was defined as standardized mortality ratio (SMR) within 30 days, ie, observed deaths of operated patients over expected deaths considering age and gender of the population in Sweden.Results: A total of 107,838 groin hernia repairs (103,710 operations), were recorded prospectively. Of 104,911 inguinal hernias, 5280 (5.1%) were treated emergently, as compared with 1068 (36.5%) of 2927 femoral hernias. Femoral hernia operations comprised 1.1% of groin hernia operations on men and 22.4% of operations on women. After femoral hernia operation, the mortality risk was increased 7-fold for both men and women. Mortality risk was not raised above that of the background population for elective groin hernia repair, but it was increased 7-fold after emergency operations and 20-fold if bowel resection was undertaken. Overall SMR was 1.4 (95% confidence interval, 1.2-1.6) for men and 4.2 (95% confidence interval, 3.2-5.4) for women, in accordance with a greater proportion of emergency operations among women compared with men, 17.0%, versus 5.1%.Conclusions: Mortality risk following elective hernia repair is low, even at high age. An emergency operation for groin hernia carries a substantial mortality risk. After groin hernia repair, women have a higher mortality risk than men due to a greater risk for emergency procedure irrespective of hernia anatomy and a greater proportion of femoral hernia.

- Objective: To analyze the relative risk of reoperation for recurrence using 3 anesthetic alternatives, general anesthesia (GA), regional (spinal-, epidural-) anesthesia (RA), and local anesthesia (LA), and to study time trends for various anesthetic and operative methods, as well as other risk factors regarding reoperation for recurrence.Background: The method of anesthesia used for hernia repair is generally assumed not to affect the long-term outcome. The few studies on the topic have rendered conflicting results.Methods: Data from the Swedish Hernia Register was used. Relative risk was first estimated using univariate analysis for assumed risk variables and then selecting variables with the highest or lowest univariate risk for multivariate analysis.Results: From 1992 through 2001, 59,823 hernia repairs were recorded. Despite the fact that univariate analysis showed a somewhat lower risk for reoperation in the LA group, the multivariate analysis showed that LA was associated with a significantly increased risk for reoperation in primary but not in recurrent hernia repair. The Lichtenstein technique carried a significantly lower reoperation risk than any other method of operation.Conclusions: LA was associated with a higher risk of reoperation for recurrence after primary hernia repair. The use of mesh techniques has increased considerably, and among these the Lichtenstein repair was associated with a significantly lower risk for reoperation than any other repair.
