Factors Associated with the Occurrence and Healing of Umbilical Pilonidal Sinus: A Rare Clinical Entity.

OBJECTIVE: Pilonidal sinus disease (PSD) is a chronic inflammatory condition of skin that is thought to be related to implanted loose hair. Although PSD is most frequently seen in the sacrococcygeal region, it can also occur at the axilla, perineum, suprapubic regions, hands, and umbilicus. The aim of this project was to find factors influencing the development and treatment of umbilical PSD. METHODS: In this retrospective study, the authors evaluated 82 patients (19 women, 63 men) with a history of umbilical PSD between 2012 and 2020 to determine predisposing factors and treatment modalities. RESULTS: There was a 20% concordance with intergluteal PSD. Smoking was the only modifying factor for recurrence. The three different treatment methods studied (conservative treatment, surgical treatment, silver nitrate) did not differ in recurrence rate (P = .57). CONCLUSIONS: Because of its rare nature, umbilical PSD can be misdiagnosed or underdiagnosed. Key aspects of treatment include smoking cessation and a conservative approach.

Optimising the outcomes of index admission laparoscopic cholecystectomy and bile duct exploration for biliary emergencies: a service model.

AIMS: The rate of acute laparoscopic cholecystectomy remains low due to operational constraints. The purpose of this study is to evaluate a service model of index admission cholecystectomy with referral protocols, refined logistics and targeted job planning. METHODS: A prospectively maintained dataset was evaluated to determine the processes of care and outcomes of patients undergoing emergency biliary surgery. The lead author has maintained a 28 years prospective database capturing standard demographic data, intraoperative details including the difficulty of cholecystectomy as well as postoperative outcome parameters and follow up data. RESULTS: Over five thousand (5555) consecutive laparoscopic cholecystectomies were performed. Only patients undergoing emergency procedures (2399,43.2% of entire group) were analysed for this study. The median age was 52 years with 70% being female. The majority were admitted with biliary pain (34%), obstructive jaundice (26%) and acute cholecystitis (16%). 63% were referred by other surgeons. 80% underwent surgery within 5 days (40% within 24 h). Cholecystectomies were performed on scheduled lists (44%) or dedicated emergency lists (29%). Two thirds had suspected bile duct stones and 38.1% underwent bile duct exploration. The median operating time was 75 min, median hospital stay 7 days, conversion rate 0.8%, morbidity 8.9% and mortality rate 0.2%. CONCLUSION: Index admission cholecystectomy for biliary emergencies can have low rates of morbidity and mortality. Timely referral and flexible theatre lists facilitate the service, optimising clinical results, number of biliary episodes, hospital stay and presentation to resolution intervals. Cost benefits and reduced interval readmissions need to be weighed against the length of hospital stay per episode.

Achieving the critical view of safety in the difficult laparoscopic cholecystectomy: a prospective study of predictors of failure.

BACKGROUND: Bile duct injury rates for laparoscopic cholecystectomy (LC) remain higher than during open cholecystectomy. The "culture of safety" concept is based on demonstrating the critical view of safety (CVS) and/or correctly interpreting intraoperative cholangiography (IOC). However, the CVS may not always be achievable due to difficult anatomy or pathology. Safety may be enhanced if surgeons assess difficulties objectively, recognise instances where a CVS is unachievable and be familiar with recovery strategies. AIMS AND METHODS: A prospective study was conducted to evaluate the achievability of the CVS during all consecutive LC performed over four years. The primary aim was to study the association between the inability to obtain the CVS and an objective measure of operative difficulty. The secondary aim was to identify preoperative and operative predictors indicating the use of alternate strategies to complete the operation safely. RESULTS: The study included 1060 consecutive LC. The median age was 53 years, male to female ratio was 1:2.1 and 54.9% were emergency admissions. CVS was obtained in 84.2%, the majority being difficulty grade I or II (70.7%). Displaying the CVS failed in 167 LC (15.8%): including 55.6% of all difficulty grade IV LC and 92.3% of difficulty grade V. There were no biliary injuries or conversions. CONCLUSION: All three components of the critical view of safety could not be demonstrated in one out of 6 consecutive laparoscopic cholecystectomies. Preoperative factors and operative difficulty grading can predict cases where the CVS may not be achievable. Adapting instrument selection and alternate dissection strategies would then need to be considered.

How participation in surgical mortality audit impacts surgical practice.

BACKGROUND: Surgical mortality audit is an important tool for quality assurance and professional development but little is known about the impact of such activity on professional practice at the individual surgeon level. This paper reports the findings of a survey conducted with a self-selected cohort of surgeons in Queensland, Australia, on their experience of participating in the audit and its impact on their professional practice, as well as implications for hospital systems. METHODS: The study used a descriptive cross-sectional survey design. All surgeons registered in Queensland in 2015 (n = 919) were invited to complete an anonymous online questionnaire between September and October 2015. 184 surgeons completed and returned the questionnaire at a response rate of 20%. RESULTS: Thirty-nine percent of the participants reported that involvement in the audit process affected their clinical practice. This was particularly the case for surgeons whose participation included being an assessor. Thirteen percent of the participants had perceived improvement to hospital practices or advancement in patient care and safety as a result of audit recommendations. Analysis of the open-ended responses suggested the audit experience had led surgeons to become more cautious, reflective in action and with increased confidence in best practice, and recognise the importance of effective communication and clear documentation. CONCLUSIONS: This is the first study to examine the impact of participation in a mortality audit process on the professional practice of surgeons. The findings offer evidence for surgical mortality audit as an effective strategy for continuous professional development and for improving patient safety initiatives.

Surgical mortality audit data validity.

BACKGROUND: Surgical audits provide constructive feedback to individual surgeons, hospitals and other healthcare sector professionals. Audits identify deficiencies in treatment processes, evaluate practice trends and detect practice gaps. The credibility and validity of the Queensland Audit of Surgical Mortality (QASM) relies on the accuracy of its data. METHODS: To determine the validity of routine reporting of surgical information to QASM, surgical case forms were compared against medical records (considered the gold standard). Data were extracted by a trained medical research assistant. QASM forensically reviewed 896 of a total of 5636 deaths in 20 Queensland public hospitals between 2008 and 2013. Concordance between the surgical case form and the relevant medical record was determined for 27 objective items. RESULTS: Overall concordance was 98.2%. The median concordance was 100% (interquartile range 87-100%). Cases with discordance were few and in these, most had only one discordant item. Discordances were mainly omissions. CONCLUSION: The QASM surgical case form is a reliable data collection tool that provides high-quality data. QASM objective data can be confidently regarded as accurate and therefore reliable for use in publications, reports and case studies.

Surgical care for the aged: a retrospective cross-sectional study of a national surgical mortality audit.

OBJECTIVES: It is assumed that increased age signifies increased surgical care. Few surgical studies describe the differences in care provided to older patients compared with younger patients. We aimed to examine the relationships between increasing age, preoperative factors and markers of postoperative care in adults who died in-hospital after surgery in Australia. DESIGN: This retrospective cross-sectional study extracted data from a national surgical mortality audit--an independent, peer-reviewed process. SETTING: From January 2009 to December 2012, 111 public and 61 private Australian hospitals notified the audit of in-hospital deaths after general anaesthetic surgery or if the patient was admitted under a surgeon. PARTICIPANTS: Notified deaths totalled 19,723. We excluded deaths if patients were brain dead, younger than 17 years or never had an operation (n=11,376). From this baseline population, we divided 11,201 deaths into three patient age groups: youngest (17-64 years), medium (65-79 years) and oldest (≥80 years). OUTCOME MEASURES: Univariable and multivariable logistic regression analyses determined the relationships between increasing age and the measured preoperative factors and postoperative variables. RESULTS: The baseline population's median age was 78 years (IQR 66-85), 43.7% (4892/11,201) were 80 years or older and 83.4% (9319/11,173) had emergency admissions. The oldest group had increased trauma and emergency admissions than the medium and youngest age groups. Seven of the eight measured markers of postoperative care demonstrate strong and significant relationships with increasing age. The oldest group compared with the medium group had decreased rates of: unplanned returns to theatre (11.2% (526/4709) vs 20.2% (726/3586)), unplanned intensive care admissions (16.3% (545/3350) vs 24.0% (601/2504)) and treatment in intensive care units (59.7% (2689/4507) vs 76.7% (2754/3590)). CONCLUSIONS: The oldest patients received lower levels of care than the medium and youngest age groups.

Mortality from acute appendicitis is associated with complex disease and co-morbidity.

BACKGROUND: Studies evaluating mortality in patients with acute appendicitis focus on the outcomes of appendicectomy alone. We hypothesize this may not be representative of what happens in clinical practice as a small proportion of patients with acute appendicitis undergo procedures other than appendicectomy, for example, caecectomy or right hemicolectomy. To clarify the issue, the authors evaluated Australian adult patients who died with a primary diagnosis of acute appendicitis regardless of whether they underwent an operation or the type of operation performed. METHODS: A cross-sectional analysis of systematically collected mortality data from the Australian and New Zealand Audit of Surgical Mortality was conducted on adults who died in hospital with a primary diagnosis of acute appendicitis between January 2009 and December 2012. RESULTS: Twenty-six patients died with a primary diagnosis of acute appendicitis. The median age was 83 years and the median number of co-morbidities was three. Four patients died without surgery due to their family's wishes. Twenty-two patients were treated surgically: five for right hemicolectomy, four for laparoscopic/McBurney appendicectomy, 10 for laparotomy with appendicectomy, two for unknown method of appendicectomy and one for open abscess drainage. CONCLUSION: Most adult patients who died following surgery for acute appendicitis did not undergo simple appendicectomy but underwent more complicated procedures for complex appendicitis.

Ward safety checklist in the acute surgical unit.

BACKGROUND: Deficiencies in daily ward rounds are increasingly identified. A ward safety checklist has recently been devised to improve the fast-paced surgical ward round. METHODS: Over 2 weeks the morning post-take surgical ward round was evaluated using the ward safety checklist. In order to avoid the Hawthorne effect, doctors involved were not aware their performance was being observed. RESULTS: One hundred patient encounters were evaluated. The three phases of the card safety checklist showed statistically significant improvement but for many components compliance was below 100%. CONCLUSION: Implementing this simple checklist has provided our unit with a starting point in how to overcome some of the deficiencies of the post-take surgical ward round.

Walled-off pancreatic necrosis: wishing our pancreatitis nomenclature was correct.

The ultimate reason why pancreatologists have strived to establish definitions for inflammatory pathologies of the pancreas is to improve patient care. Although the Atlanta Classification has been used for around for 17 years, considerable misunderstanding of the key elements of the nomenclature still persists. While a recent article by Stamatakos et al aimed to deal with an entity not clearly defined in the 1993 document, it is replete with factual and conceptual errors as well as contradictory statements.
