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,...
Laparoscopic cholecystectomy for acute inflammation of the gallbladder is safe and is associated with a significantly shorter postoperative stay compared to open surgery. A greater number of patients required conversion to open operation compared to those with no obvious inflammation. Conversion to open operation was most frequent for empyema and gangrenous cholecystitis, suggesting that once this diagnosis is made, excessive time should not be spent in laparoscopic trial dissection before converting to an open operation.
The surgical approach to oesophagectomy was not an important determinant of morbidity and long-term survival in patients with oesophageal carcinoma. Transhiatal oesophagectomy was associated with a higher incidence of anastomotic complications and recurrent laryngeal nerve injury. Ivor-Lewis oesophagectomy had a higher mortality. In order to demonstrate a significant difference in morbidity or long-term survival between the two techniques 3100 patients would be required in each arm of a prospective randomized trial.
The traditional on-call system for the management of acute general surgical admissions is inefficient and outdated. A new model, Acute Surgical Unit (ASU), was developed at Nepean Hospital in 2006. The ASU is a consultant-driven, independent unit that manages all acute general surgical admissions. The team has the same make up 7 days a week and functions the same every day, including weekends and public holidays. The consultant does a 24-h period of on-call, from 7 pm to 7 pm. They are on remote call from 7 pm to 7 am and are in the hospital from 7 am to 7 pm with their sole responsibility being to the ASU. The ASU has a day team with two registrars, two residents and a nurse practitioner. All patients are admitted and stay in the ASU until discharge or transfer to other units. Handover of the patients at the end of each day is facilitated by a comprehensive ASU database. The implementation of the ASU at Nepean Hospital has improved the timing of assessment by the surgical unit. There has been significant improvement in the timing of operative management, with an increased number and proportion of cases being done during daylight hours, with an associated reduction in the proportion of cases performed afterhours. There is greater trainee supervision with regard to patient assessment, management and operative procedures. There has been an improvement in the consultants' work conditions. The ASU provides an excellent training opportunity for surgical trainees, residents and interns in the assessment and management of acute surgical conditions.
SUMMARY BackgroundCoeliac disease has been associated with an increased risk of mortality and malignancy. However, the strength of this association is conflicting among different studies.
Local recurrence (LR) continues to be a major problem following surgical treatment for rectal cancer, and proposed ways of reducing this remain controversial. The aim of this study was to review results from published surgical series in which adjuvant therapies were not used. A Medline search identified series published between January 1982 and December 1992 with follow-up on at least 50 patients with rectal cancer treated surgically for cure, without adjuvant therapy. Fifty one papers reported follow-up on 10,465 patients with a median LR rate of 18.5%. LR was 8.5%, 16.3% and 28.6% in Dukes' A, B and C patients respectively, 16.2% following anterior resection and 19.3% following abdominoperineal resection. Nine papers (1,176 patients) reported LR rates of 10% or less. LR was 7.1% in 1,033 patients having total mesorectal excision and 12.4% in 476 patients having extended pelvic lymphadenectomy. Routine cytocidal stump washout in 1,364 patients was associated with 12.2% LR, however a higher proportion (41%) also underwent total mesorectal excision. In 52% of cases, LR was reported to have occurred with no evidence of disseminated disease. Surgical technique is an important determinant of LR risk. LR rates of 10% or less can be achieved with surgery alone in expert hands.
Postoperative adhesions account for 64–79% of admissions with small bowel obstruction (SBO). The aim of this study was to identify the operative procedures and the types of adhesions that cause SBO. A retrospective analysis of all patients with an admission diagnosis of acute adhesive SBO between January 1982 and December 1990 was performed. One hundred and nineteen patients had 144 admissions with an initial diagnosis of acute SBO due to adhesions. The previous operations were: appendicectomy 23.3%; colorectal resection 20.8%; gynaecological surgery 11.7%; upper gastrointestinal (gastric, biliary or splenic) surgery 9.2%; small bowel surgery 8.3%; and more than one previous abdominal operation 23.6%. Sixty‐one admissions required surgery to relieve the SBO. Eighteen patients had strangulated small bowel. All but two of these patients had a single band adhesion causing the SBO and associated strangulation. Band adhesions were commonly found following appendicectorny, colorectal resections or gynaecological operations. Seventeen of the 21 patients with previous surgery for a colorectal malignancy had benign adhesions causing the SBO, while four of the six patients with either previous ovarian or previous gastric carcinoma had recurrent malignancy causing the SBO. Five patients had previously undiagnosed carcinomas (three ovarian and two caecal) as the cause of the SBO.
A prospective, randomized trial was performed to compare open appendectomy with laparoscopic appendectomy in men with a clinical diagnosis of acute appendicitis. Sixty-four patients with a median age of 25 years (range 18-84 years) were randomized to open appendectomy (n = 31) or laparoscopic (n = 33) appendectomy. Of the 64 men, 56 (87.5%) had appendicitis (27 open, 29 laparoscopic procedures). The mean operating times were 50.6 +/- 3.7 minutes (+/- SEM) for open and 58.9 +/- 4.0 minutes for laparoscopic appendectomy (p = 0.13). Five (15%) patients randomized to laparoscopic appendectomy had an open operation. The mean postoperative hospital stay was significantly longer for open appendectomy (3.8 +/- 0.4 days) than for laparoscopic appendectomy (2.9 +/- 0.3 days) (t = 2. 05,df = 62,p = 0.045). The complication rate after open appendectomy (25.8%) was not significantly different from that after laparoscopic appendectomy (12.1%). There was a single postoperative death due to a pulmonary embolus in the laparoscopic group and a single death due to cardiac and renal failure in the open group. The mean time to return to normal activities was significantly longer following open appendectomy (19.7 +/- 2.4 days) than after laparoscopic appendectomy (10.4 +/- 0.9 days), (t = 3.75,df = 49,p = 0.001). In conclusion, laparoscopic appendectomy in men has significant advantages in terms of a more rapid recovery compared to open appendectomy. There were no significant disadvantages to laparoscopic appendectomy compared to open appendectomy.
