Contralateral metachronous inguinal hernias in adults: role for prophylaxis during the TEP repair.

PURPOSE: Contralateral exploration during laparoscopic totally extraperitoneal (TEP) inguinal herniorrhaphy allows for the repair of incidentally found hernias. Nonetheless, some patients with a negative contralateral exploration subsequently develop a symptomatic hernia on that side. We pondered the incidence of contralateral metachronous hernia development and whether prophylactic "repair" in these circumstances would be beneficial. METHODS: A retrospective analysis of patients who underwent laparoscopic TEP exploration at our institution was performed. Demographic, operative and follow-up information was obtained through medical record review, physical examination and telephone/mailed survey. RESULTS: From 1995 to 2009, a total of 1,479 inguinal herniorrhaphies on 976 patients were performed by a single staff surgeon. Bilateral exploration was completed in 923 (95%) of these patients, of whom bilateral repair was performed on 503 (55%). The study cohort comprises the 409 (42%) patients having a unilateral repair with a negative contralateral exploration and no previous contralateral hernia repair (n = 11). With a median follow-up of 5.9 years (range 0-14), 33 (8.1%) hernias developed on the previously "healthy" side, yielding incidence rates at 1, 5 and 10 years of 1.6, 5.9 and 11.8%, respectively. The median time to hernia development was 3.7 years (range 0.1-12.4). Of the 30 inguinal hernias that have been repaired, 25 (83%), 3 (10%) and 2 (7%) were of indirect, direct and pantaloon types, respectively. CONCLUSIONS: When considering prophylactic repair during TEP explorations, a yearly risk of 1.2% of developing a contralateral hernia after negative exploration needs to be balanced against the low but potential risk of groin pain following prophylactic repair.

Consequences of endoscopic inguinal hernioplasty with mesh on subsequent open radical prostatectomy.

AIM: To determine the effect of prior endoscopic hernia repair with prosthetic mesh on subsequent open radical prostatectomy. METHODS: A retrospective study from 1990 to 2004 identified nine patients with preperitoneal mesh placement followed by open radical prostatectomy. Case controls (n = 26) were matched for age, type of operation, year of surgery and pathologic stage of prostatic adenocarcinoma. Outcome variables of operating time, number of pelvic lymph nodes excised, duration of hospital stay, duration of urinary catheterization, recurrence rates, and incidence of complications were compared. Data analysis was performed using Wilcoxon's rank sums test. RESULTS: Intraoperatively, subjective difficulty in dissection was documented in all cases by the performing urologist. Duration of hospital stay was significantly increased by 1.3 days (p < 0.05), as compared to the control group. However, no statistically significant increase in mean operating time (173 vs. 172 min, p = 0.925), number of lymph nodes sampled (4.4 vs. 6.6, p = 0.147), duration of urinary catheterization (22 vs. 19 days, p = 0.925), oncologic recurrence (11 vs. 11% at 6.1 and 4.8 years follow-up), or complications was found. CONCLUSIONS: Prior TEP/TAPP did not increase the morbidity or mortality of subsequent prostate surgery. Despite some subjective operative difficulty, open prostatectomy was safe and feasible in all cases with a comparable oncologic outcome. Mesh-associated inflammation may preclude adequate nodal sampling. While endoscopic hernia repair remains an excellent option to fix unilateral, bilateral, and recurrent herniae, consideration of future prostate surgery is important. Inserting less "inflammatory" mesh or using an open, anterior approach may be prudent in some men at high risk for needing subsequent prostate surgery.

Postoperative hematoma following inguinal herniorrhaphy: patient characteristics leading to increased risk.

BACKGROUND: Although relatively infrequent, groin hematoma following inguinal herniorrhaphy is a morbid complication with major ramifications of mesh infection and hernia recurrence. We have sensed an increasing frequency of this complication in our tertiary referral practice and sought to determine whether or not significant risk factors could be identified. METHODS: In this matched case-control study (1995-2003), we identified 53 patients with groin hematomas and paired them with 106 age- and gender-matched controls. Patient and procedure characteristics were analyzed using chi-square and both univariate and multivariable, conditional logistic regression analysis. RESULTS: The 53 patients developing groin hematoma following inguinal hernia repair (mean age=65, range 22-87, 90% male) were well matched with 106 controls (mean age=65, range 22-87, 90% male). There was no significant difference in the location (left, right, bilateral), type (direct, indirect, pantaloon, first repair, or recurrent), or technique of hernia repair (Bassini, Lichtenstein, mesh plug, endoscopic, or McVay) between groups. While univariate analysis identified Coumadin usage (P<0.001, hazard ratio 19.1), valvular disease (P<0.001, hazard ratio 10.9), atrial fibrillation (P=0.02, hazard ratio 4.2), vascular disease (P=0.04, hazard ratio 2.2), blood abnormalities (P=0.02, hazard ratio 3.2), and previous bleeding episodes (P=0.02, hazard ratio 4.9) as significant factors, only preoperative Coumadin usage was important in multivariate analysis. CONCLUSION: The crucial risk factor for groin hematoma developing in patients undergoing inguinal hernia repair is preoperative need for Coumadin therapy. Although the perioperative management of anticoagulation in patients undergoing inguinal herniorrhaphy is not clearly defined, meticulous management of patients requiring Coumadin therapy seems prudent.

AIDS and college students: a survey of knowledge, attitudes and beliefs.

A survey of beliefs about, knowledge of, and attitudes about AIDS was administered to 345 college students. While knowledge was generally high, reported behavior was not always consistent with that knowledge.
