This novel technique seems to be safe and effective in the treatment of outlet obstruction caused by the combination of intussusception and rectocele. Randomized trials are required to confirm these findings.
SummaryBackgroundSurgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.MethodsThis international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.FindingsBetween Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001).InterpretationCountries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.FundingDFID-MRC-Wellcome Trust Joint Global Health Trial Development Grant,...
Stapled hemorrhoidectomy (SH), a new approach to the treatment of hemorrhoids, removes a circumferential strip of mucosa about four centimeters above the dentate line. A review of 1,107 patients treated with SH from twelve Italian coloproctological centers has revealed a 15% (164/1,107) complication rate. Immediate complications (first week) were: severe pain in 5.0% of all patients, bleeding (4.2%), thrombosis (2.3%), urinary retention (1.5%), anastomotic dehiscence (0.5%), fissure (0.2%), perineal intramural hematoma (0.1%), and submucosal abscess (0.1%). Bleeding was treated surgically in 24%, with Foley insertion 15%; and by epinephrine infiltration in 2%; 53% of patients with bleeding received no treatment and 6% needed transfusion. One patient with anastomotic dehiscence needed pelvic drainage and colostomy formation. The most common complication after 1 week was recurrence of hemorrhoids in 2.3% of patients, severe pain (1.7%), stenosis (0.8%), fissure (0.6%), bleeding (0.5%), skin tag (0.5%), thrombosis (0.4%), papillary hypertrophy (0.3%) fecal urency (0.2%), staples problems (0.2%), gas flatus and fecal incontinence (0.2%), intramural abscess, partial dehiscence, mucosal septum and intussusception (each <0.1%). Recurrent hemorrhoids were treated by ligation in 40% and by Milligan-Morgan procedure in 32%. All hemorrhoidal thromboses were excised. Anal stenoses were treated by dilatation in 55% and by anoplasty in 45%. Fissure was treated by dilatation in 57%. Most complications (65%) occurred after the surgeon had more than 25 case experiences of stapled hemorrhoidectomy. The most common complication in the first 25 cases of the surgeon's experience was bleeding (48%). Even though SH appears to be promising, we feel that a multicenter randomized study with a long-term follow-up comparing SH and banding is necessary before recommending the procedure. Most complications can be avoided by respecting the rectal wall anatomy in the execution of the procedure.
A grading system of anal incontinence (AI) is described that takes into account both degree and frequency of symptoms. A, B, and C indicate AI for flatus/mucus, liquid stool, and solid stool, respectively; 1, 2, and 3 indicate occasional, weekly, and daily AI. A scoring system, ranging from 0 (continence) to 6 (severe AI, i.e., daily AI for solid stool or C3) also is reported. Three hundred thirty-five patients have been evaluated by this method in our institution: 30 percent had severe AI, graded as C3; only 9 percent had mild symptoms graded as A. Both males and females could not control diarrhea (Grade B) in 44 percent of cases. Nearly half of the 110 patients who underwent surgery had a C3 incontinence before treatment. Positive results were achieved in 75 percent of cases after surgery: e.g., AI score significantly improved from 4.2 +/- 1.6 to 1.5 +/- 1.9 (P less than 0.001) in those with AI and rectal prolapse. Most of the failures were the patients with idiopathic C3 incontinence. In conclusion, this grading and scoring system allowed a satisfactory assessment of patients' AI before and after treatment. It may also be used to achieve an objective comparison between different series.
Stapled transanal rectal resection achieved acceptable results at the cost of a high reoperation rate. Patients with puborectalis dyssynergia and lower bowel frequency may do worse because surgery does not address the causes of their constipation. Patients with large rectoceles, enteroceles, digitation, and a sense of incomplete evacuation may have more advanced pelvic floor disease for which stapled transanal rectal resection, which simply removes redundant tissue, may not be adequate. This, together with the complications observed in patients referred after stapled transanal rectal resection, suggests that this procedure should be performed by colorectal surgeons and in carefully selected patients.
