How can we improve our practices in obstetric anal sphincter injury prevention, diagnosis, and management of symptomatic women?

Obstetric anal sphincter injury (OASI) is strongly associated with a major negative impact on women's health. Due to the consequences of an undiagnosed and therefore unrepaired OASI, it is essential to prevent or at least diagnose OASI at childbirth. We need to promote training of professionals to improve OASI screening at childbirth. High-risk situations such as operative delivery must be identified and preventive strategies such as the choice of a less traumatic instrument (vacuum) and mediolateral episiotomy should be considered. For a woman with OASI and/or symptoms, postnatal consultation with a specialist on pelvic floor disorders is essential to correctly orient her toward an adequate care pathway and to eventually identify occult or underestimated OASI. More data are required on therapeutic approaches for symptomatic women, primarily including physical therapy, sacral neuromodulation, delayed sphincter repair and palliative devices.

A comparison of surgical devices for grade II and III hemorrhoidal disease. Results from the LigaLongo Trial comparing transanal Doppler-guided hemorrhoidal artery ligation with mucopexy and circular stapled hemorrhoidopexy.

PURPOSE: Little is presently known on the impact of device type for Doppler-guided hemorrhoidal artery ligation/mucopexy (DGHAL) or circular stapled hemorrhoidopexy (CSH) when a surgical treatment is considered for hemorrhoidal disease (HD). In this study, we aimed to compare the outcome in terms of adverse events and recurrence rate, of patients included in the multicenter LigaLongo RCT ( ClinicalTrials.gov NCT01240772) according to the type of devices used. METHODS: In the DGHAL arm (N = 193), the procedure was done with transanal hemorrhoidal dearterialization (THD)™ (THD, Correggio, Italy) (104 patients) and with HAL-RAR™ (Agency for Medical Innovations (AMI) GmbH, Feldkirch, Austria) (89 patients). In the CSH arm (N = 184), procedure for prolapse and hemorrhoids (PPH)-03™ (Ethicon Endo-Surgery, Cincinnati OH) and hemorrhoidopexy and prolapse (HEM)™ (Covidien, Inc.) staplers were used in respectively 106 and 78 cases. Surgery-related morbidity at 90 postoperative days (POD) based on the Clavien-Dindo procedure-related complication score and clinical outcome in terms of recurrence and reoperation rate at 12 postoperative months (POM) was collected. RESULTS: Three hundred and seventy-seven patients were randomized according to HD grade. In the DGHAL arm, the number of ligations and mucopexies was higher in the AMI group (p < 0.0001); at 90 POD, the overall morbidity was similar between the two groups. In the CSH arm, donut sizes were similar; at 90 POD, the PPH group had a higher risk of postoperative grade 1 morbidity (anal urgency or incontinence) compared to the HEM group (p = 0.003). At 12 POM, no statistical difference was found between the two groups of each arm in terms of grade III recurrence or reoperation. CONCLUSION: Postoperative morbidity and outcome at 1 year were similar regardless of the type of devices used. These findings suggest that device type has little impact on HD treatment results.

To Drain or Not to Drain Infraperitoneal Anastomosis After Rectal Excision for Cancer: The GRECCAR 5 Randomized Trial.

OBJECTIVE: To assess the effect of pelvic drainage after rectal surgery for cancer. BACKGROUND: Pelvic sepsis is one of the major complications after rectal excision for rectal cancer. Although many studies have confirmed infectiveness of drainage after colectomy, there is still a controversy after rectal surgery. METHODS: This multicenter randomized trial with 2 parallel arms (drain vs no drain) was performed between 2011 and 2014. Primary endpoint was postoperative pelvic sepsis within 30 postoperative days, including anastomotic leakage, pelvic abscess, and peritonitis. Secondary endpoints were overall morbidity and mortality, rate of reoperation, length of hospital stay, and rate of stoma closure at 6 months. RESULTS: A total of 494 patients were randomized, 25 did not meet the criteria and 469 were analyzed: 236 with drain and 233 without. The anastomotic height was 3.5 ±â€Š1.9 cm from the anal verge. The rate of pelvic sepsis was 17.1% (80/469) and was similar between drain and no drain: 16.1% versus 18.0% (P = 0.58). There was no difference of surgical morbidity (18.7% vs 25.3%; P = 0.83), rate of reoperation (16.6% vs 21.0%; P = 0.22), length of hospital stay (12.2 vs 12.2; P = 0.99) and rate of stoma closure (80.1% vs 77.3%; P = 0.53) between groups. Absence of colonic pouch was the only independent factor of pelvic sepsis (odds ratio = 1.757; 95% confidence interval 1.078-2.864; P = 0.024). CONCLUSIONS: This randomized trial suggests that the use of a pelvic drain after rectal excision for rectal cancer did not confer any benefit to the patient.

Safety of laparoscopic ventral rectopexy in the elderly: results from a nationwide database.

BACKGROUND: Laparoscopic ventral rectopexy is an established procedure in the treatment of posterior pelvic organ prolapse. It is still unclear whether this procedure can be performed safely in the elderly. OBJECTIVE: This study aimed to assess the effects of age on the outcome of laparoscopic ventral rectopexy performed for patients with pelvic organ prolapse. DESIGN: This study was a retrospective cohort analysis with data from a national registry. SETTINGS: The study was conducted in a tertiary care setting. PATIENTS: Patients undergoing laparoscopic ventral rectopexy were identified from discharge summaries. Patients were stratified according to age, including patients <70 (group A) and ≥ 70 (group B) years old. MAIN OUTCOME MEASURES: Variables analyzed included sex, age, diagnosis, associated pelvic organ prolapse, comorbidities, length of stay, complications (Clavien-Dindo scale), and mortality. RESULTS: Among 4303 patients (98.2% women) who underwent a laparoscopic ventral rectopexy, 1263 (29.4%) were >70 years old (mean age, 76.2 ± 5.0 years). Main diagnoses were vaginal vault prolapse (53.0% [group A] vs 47.0% [group B]; p value not significant) and rectal prolapse (17.7 vs 26.8%; p value not significant). Comorbidity was significantly increased in group B (mean length of stay, 5.6 ± 3.6 vs 4.7 ± 1.8 days; p < 0.001) and minor complications (8.4% vs 5.0%; p < 0.001) were significantly increased in group B, whereas major complications were not different (group A, 0.7%; group B, 0.9%; p = 0.40) after univariate analysis. Multivariate analysis found no significant differences between groups. The subgroup analysis of patients >80 years old (n = 299) showed no differences. Each group had 1 postoperative mortality. LIMITATIONS: Limitations of the study include its retrospective design, lack of prestudy power calculation, possible inaccuracy of an administrative database, and selection bias. CONCLUSIONS: Laparoscopic ventral rectopexy appears to be safe in select elderly patients.

Acute humoral rejection of renal transplants in alloimmunized pigs.

BACKGROUND: Despite progress in immunosuppression, acute humoral rejection (AHR) remains an unsolved issue in transplantation, with a possible reversibility in only about 50% of cases. AHR is characterized by antidonor antibodies in the recipient circulation and characteristic histological lesions within the graft itself, as well as complement degradation products and immunoglobulins (IgM and IgG) deposition in vascular zones. The lack of a large animal models of AHR in experimental allotransplantation led us to establish such a model in the pig. MATERIALS AND METHODS: Pigs were immunized with peripheral blood mononuclear cells from allogeneic donors and subsequently received a kidney from the same donor, once antidonor antibodies (Ab) had reached a plateau. The efficiency of the alloimmunization, the nature of the induced antibodies and rejection were studied. RESULTS: Six out of seven recipients developed specific antidonor Ab. Three days post-transplantation, characteristic lesions of AHR were observed together with intragraft IgG, IgM, and complement deposition. The AlloAb were found to be cytotoxic and directed against donor MHC class I molecules. CONCLUSIONS: We described, for the first time, a large animal model of AHR, which will enable us to more extensively study phenomena implicated in AHR and to test new strategies aimed at its prevention or cure, as well as improve transplant protocols in the case of presensitized or hyperimmunized patients.
